RGV (Rail Guided Vehicle) is a common transfer tool in liquid injection and formation apparatus, and the RGV can transfer a liquid injection jig from a liquid injection device to a standing device, and after standing, the RGV transfers the liquid injection jig to a discharging station. At present, most common RGVs have a single-sided transfer structure, that is, the liquid injection jig can only be transferred on the same side of the RGV, which affects the transportation efficiency of the RGV, and limits the spatial distribution of the liquid injection and formation apparatus.

Of course, as for the transfer auxiliary fixing assembly, it can be understood that: in some examples, a plurality of transfer auxiliary fixing assemblies are provided, and are arranged on the bidirectional transfer base 1000 at an interval along the transfer direction, so as to fix the position of the liquid injection jig more firmly.
The bidirectional transfer device comprises a first transfer positioning sensor 4100. The first transfer positioning sensor 4100 is connected to the bidirectional transfer base 1000 and configured for detecting a moving position of the liquid injection jig on the bidirectional transfer device. Specifically, the first transfer positioning sensor 4100 is implemented by an opposed photoelectric sensor or an opposed grating.
In some examples, two first transfer positioning sensors 4100 are provided. Along the transfer direction, the two first transfer positioning sensors 4100 are arranged at an interval on the bidirectional transfer base 1000. It can be understood that the position of the liquid injection jig is detected by using the two first transfer positioning sensors 4100, which is convenient to change the position of the bidirectional transfer auxiliary assembly 3000 relative to the liquid injection jig to realize handover of the bidirectional auxiliary push-pull component 3100.
In some examples, the bidirectional transfer device comprises a second transfer positioning sensor. The second transfer positioning sensor is implemented by an opposed photoelectric sensor or an opposed grating. The second transfer positioning sensor is configured for detecting a moving position of the bidirectional transfer arm assembly 2000. Specifically, if the second transfer positioning sensor is triggered during the outward protruding of the bidirectional transfer arm assembly 2000, it means that the bidirectional transfer arm assembly 2000 is protruded in place.
In some examples, the bidirectional transfer device comprises a third transfer positioning sensor. The third transfer positioning sensor is implemented by an opposed photoelectric sensor or an opposed grating. The third transfer positioning sensor is configured for monitoring a moving position of the bidirectional transfer auxiliary assembly 3000. Specifically, when the bidirectional transfer arm assembly 2000 is protruded in place, the bidirectional auxiliary push-pull component 3100 moves to the protruded position relative to the bidirectional transfer arm assembly 2000 in order to pull or push out the liquid injection jig. If the third transfer positioning sensor is triggered, it means that the bidirectional auxiliary push-pull component 3100 is protruded in place.
In the following, the process of conveying the liquid injection jig by the bidirectional transfer device in the disclosure is described in detail with a specific embodiment. It should be noted that the following description is only an example, and is not a specific limitation of the disclosure.
With reference to
A liquid injection jig to be transferred is located at one side of the bidirectional transfer device. If the liquid injection jig to be transferred is far away from the bidirectional transfer device, the bidirectional transfer arm assembly 2000 protrudes along the first direction.
After the bidirectional transfer arm assembly 2000 protrudes in place, the bidirectional transfer auxiliary assembly 3000 moves along the first direction, and the bidirectional transfer auxiliary assembly 3000 protrudes relative to the bidirectional transfer arm assembly 2000, so that the bidirectional auxiliary push-pull component 3101 at a first end of the auxiliary push-pull component 3100 is connected to the liquid injection jig. It can be understood that before or during the movement of the bidirectional transfer auxiliary assembly 3000 along the first direction, the bidirectional auxiliary push-pull component 3100 is in a descended position, and after the bidirectional transfer auxiliary assembly 3000 protrudes in place, the bidirectional auxiliary push-pull component 3100 ascends, so that the auxiliary push-pull connecting component 3101 can be connected to the lower side of the liquid injection jig.
After the auxiliary push-pull connecting component 3101 is connected to the liquid injection jig, the bidirectional transfer auxiliary assembly 3000 moves along the second direction to pull the liquid injection jig onto the bidirectional transfer arm assembly 2000.
The bidirectional transfer arm assembly 2000 moves along the second direction to transfer the liquid injection jig along the second direction. It can be understood that in this process, the bidirectional transfer auxiliary assembly 3000 is stationary relative to the bidirectional transfer arm assembly 2000, and the auxiliary push-pull connecting component 3101 keeps connected to the liquid injection jig, which facilitates to fix the position of the liquid injection jig.
While the bidirectional transfer arm assembly 2000 transfers the liquid injection jig along the second direction, the first transfer positioning sensor 4100 monitors a moving distance of the liquid injection jig, and if the moving distance of the liquid injection jig reaches a first set distance, the transfer auxiliary fixing assembly clamps and fixes the liquid injection jig.
The bidirectional auxiliary push-pull component 3100 descends, the bidirectional transfer auxiliary assembly 3000 moves along the first direction to reach below the liquid injection jig, the bidirectional auxiliary push-pull component 3100 ascends, and the auxiliary push-pull connecting component 3101 of the bidirectional auxiliary push-pull component 3100 is connected to the liquid injection jig.
The transfer auxiliary fixing assembly releases the fixing of the liquid injection jig, and the bidirectional transfer auxiliary assembly 3000 moves along the second direction to push the liquid injection jig to move on the bidirectional transfer arm assembly 2000. The first transfer positioning sensor 4100 monitors the moving distance of the liquid injection jig, and if the moving distance of the liquid injection jig reaches a second set distance, the transfer auxiliary fixing assembly clamps and fixes the liquid injection jig.
The bidirectional auxiliary push-pull component 3100 descends, the bidirectional transfer auxiliary assembly 3000 moves along the first direction, and the bidirectional auxiliary push-pull component 3100 ascends, so that the auxiliary push-pull connecting component 3101 at a second end of the bidirectional auxiliary push-pull component 3100 is connected to the liquid injection jig.
The transfer auxiliary fixing assembly releases the fixing of the liquid injection jig, and the bidirectional transfer arm assembly 2000 moves along the second direction to transfer the liquid injection jig along the second direction.
After the bidirectional transfer arm assembly 2000 protrudes in place, the bidirectional transfer arm assembly 2000 stops moving, and the bidirectional transfer auxiliary assembly 3000 moves along the second direction to push the liquid injection jig out of the bidirectional transfer arm assembly 2000.
It should be noted that two first transfer positioning sensors 4100 are used to obtain the first set distance and the second set distance. Specifically, the liquid injection jig moves by the first set distance to trigger the first transfer positioning sensor 4100, and the liquid injection jig continues to move by the second set distance to trigger the other first transfer positioning sensor 4100.
In some examples, if the RGV is moved by means of the RGV transport rail 7100, the liquid injection jig is transferred from one end to the other on the same side of the RGV transport rail 7100. In this case, after the bidirectional transfer auxiliary assembly 3000 pulls the liquid injection jig on one side of the RGV to the bidirectional transfer arm assembly 2000, the RGV moves in place, and the bidirectional transfer auxiliary assembly 3000 pushes the liquid injection jig out to the same side of the RGV.
