The present invention relates generally to an auto-assembling system, and more specifically to an auto-assembling system that combines the motor and the machine utilized to auto-assemble and collect the frames and the covers of the electronic devices.
The mobile phone industry of Taiwan can be substantially divided into two segments. One is the up stream industry for providing the components and another segment involves the manufacture of the mobile phone. As to the up stream industry, for examples, includes the printed circuit board (PCB), connecter, the housing, the key board, the panel, etc. Because of the product quality is better than other areas, the manufacture costs in Taiwan are also lower than the one of the supplier in Europe, America and Japan, thus, the goods made by Taiwan is graced by the overseas merchants. In the manufacture of the mobile phone, owing to the reduction of the selling price of the mobile phone in GSM at present, and the prices of mobile phone still decline every year forced the mobile phone factories to lower the overhigh manufacture and its costs.
Under the circumstance of the growing sales of the mobile phone with each passing day, the demands of the amounts every year are about at least six hundred million, and the demands in Taiwan are ten millions. To face the huge amounts of products, every electronics and information factory is conscious of the lack of the employees, the human resources and the increasing of the production costs, and transfers the manufacture factories to abroad.
As to the regard of the competition, the Taiwan factories receive the orders of the foreign factories under the trend of the low price in the mobile phone, consequently, the ability of lowering the costs is naturally important. Hence, Taiwan manufacture factories are enforced to urgently improve their production ability, such that they can consolidate their pass orders and not snatched by China which having the predominance in manufacture.
In the past, the part of the assembling production was almost operated by the manpower. The traditional assembling production line and the collecting operation of the devices are low efficiency, a lot of working space and taking the wrong collection by personal negligence, such that they always receive the complaints from customers or the factories suffer the damages. And many workers are needed in a production line and these will raise the costs of manufacture. As know in art, the efficiency of the assembling operation by manual is about one product per two seconds. That is to say, working for eight hours every day can accomplish the production amounts of 8 (hours)×60 (minutes)×60 (seconds)/2 (seconds)=14,400 products/day, an ideal amount of the production calculated by a nonstop worker, but actually each worker always needs to take rest. Nevertheless, each works needs working space and will be paid.
However, under the consideration of high quality products, the automatic equipments are adopted in production testing processes to improve the yields of the products through the changes of the manufacture flows. The yields improvement is the key to the costs reduction. If the production is transferred to abroad, they must face the problems of the retraining of the employees and the improvement of the learning curve. These problems are the obstructers of the improvement of the yield.
In view of above-mentioned, the efficiency of the traditional laboring work is not high and a large number of operators are needed at the same time. These reflect on the manufacture cost. However, lowering the cost, saving the space and reaching the same capability for production are not achieved by the management of manpower. Therefore, take a step to automatize the production can qualify and improve the capacity for production, lower the production cost and raise the profit.
Corresponding to the division of labor of the information industry, the manufacture industry of the mobile phone is a highly integrated sunrise industry. Thereof, the automated operation mode of manufacture is fit for the demands of the product production in modern industry (various product, short life time, product qualification and various and a few product) to improve the capability of competition.
The object of the present invention is to provide an auto-assembling system integrating the above-mentioned demands and utilized to auto-assemble the devices to improve the whole production efficiency. That can be used on the auto-assembling system in the production line, and molded upon on the production of the various shell devices to overcome the overhigh problems of the manpower and the production costs.
Some sample embodiments of the invention will now be described in greater detail. Nevertheless, it should be recognized that the present invention can be practiced in a wide range of other embodiments besides those explicitly described, and the scope of the present invention is expressly not limited except as specified in the accompanying claims. Then, the components of the different elements are not shown to scale. Some dimensions of the related components are exaggerated and meaningless portions are not drawn to provide a more clear description and comprehension for the present invention.
In view of above-mentioned, the object of the present invention is to disclose an auto-assembling system for assembling the frames and the covers of the devices by combining the motor and the control circuit.
Another object of the present invention is to disclose a conveniently auto-assembling system for assembling the frames and the covers of the devices, collecting efficiently and lowering the risk of gaining not equal to the production corresponding to the placement of the a number of labors.
The present invention discloses an auto-assembling system for assembling the frames and the covers of devices. The auto-assembling system configured on a platform includes a transportation device, a lateral assembling power module, a buffer, a control circuit and a power source. The above-mentioned transportation device has a fillister for receiving a frame and a cover of a device. A lateral assembling power module responds to the transportation device to drive the frames and the covers in the transportation device, so that the frames and the covers are substantially combined with each other. A buffer is used as a cushion for a lateral assembling power module, when the lateral assembling power module move to the buffer, the frames and the covers are assembled. A control circuit connects to the lateral assembling power module for controlling the activating timing of the lateral assembling power module. A power source connects to the lateral assembling power module and the control circuit to provide the power for the lateral assembling power module and the control circuit.
