Patent Application
20130139475
The invention relates to the field of liquid crystal displays, and more particularly to a packing bag of a liquid crystal display (LCD) and a packing method thereof.
A TFT-LCD liquid crystal display includes a backlight module, a liquid crystal panel, a bezel, etc. The liquid crystal display can be formed by assembling those components. Thereafter, a worker puts the liquid crystal display into a packing bag, and then put the packing bag into a carton for final package and shipment. Conventional packing methods generally include two types:
One is that the worker puts the liquid crystal display into the packing bag, which is further sealed by a sealing machine. The method uses the sealing machine to seal the packing bag, thus increasing equipment cost, reducing production efficiency, and being inconvenient for reuse and recovery.
The other is that a packing bag is folded for easy sealing. The packing bag is made of antistatic material. Sealed by the folding method, the packing bag shall be designed such that the overall dimensions of the packing bag are significantly larger than those of the module. Therefore, the material cost is increased, wrinkles and damage easily occur, and recovery and reuse are difficult. The packing bag often stretches due to its tension after folding, so external particles easily enter the module and cause contamination, or the stretched packing bag is effected by moisture, which is adverse to dust and damp prevention.
The aim of the invention is to provide a packing bag of a liquid crystal display (LCD) and a packing method thereof that has a low cost and can be recovered.
The purpose of the invention is achieved by the following technical schemes:
A packaging bag of a liquid crystal display comprises a bag body and an opening, wherein a sealing structure which can be repeatedly unsealed/sealed is disposed at the opening.
Preferably, the sealing structure is a sealed structure, with advantages of dust and damp prevention and improvement of yield rate of the liquid crystal display.
Preferably, the sealing structure comprises a first chain and a second chain which are arranged on both sides of the opening. The first chain is provided with male parts or female parts. The second chain is provided with female parts or male parts matched with and secured to the first chain. This is a specific form of the sealing structure. The male parts are inserted into the female parts to fasten the sealing structure. Therefore, the sealing structure of the packing bag has favorable sealing performance, and can effectively prevent dust and moisture from entering the packing bag to avoid damage to the liquid crystal display.
Preferably, the sealing structure is provided with a zipper puller. Both sides of the zipper puller clamp the outsides of the first chain and the second chain. The zipper puller is convenient for sealing or unsealing the opening. Both sides of the zipper puller clamp the outsides of the first chain and the second chain to press the male parts into the female parts and realize sealing.
Preferably, the middle of the zipper puller is provided with a boss for unsealing the opening. The boss is located between the male parts and the female parts. When the opening is unsealed, the zipper puller is moved in the unsealing direction to separate the male parts from the female parts and realize unsealing.
Preferably, the packing bag is provided with one zipper puller. One zipper puller can save cost, and is located at one end of the opening when the opening is sealed. The sealing structure has favorable sealing performance.
Preferably, the packing bag is provided with two zipper pullers. When a large liquid crystal display is packed, the two zipper pullers can be moved to the canter from both ends of the sealing structure thereby saving the operation time.
Preferably, the sealing structure is made of plastic material. The sealing structure made of plastic material has certain elasticity and favorable sealing performance, improves the dust and damp prevention effect, and does not easily scratch the liquid crystal display.
Preferably, the sealing structure is made of antistatic material. Friction between the sealing structure and the packing bag occurs when the liquid crystal display is put into or removed from the packing bag; the friction causes static discharge. Therefore, the sealing structure made of the antistatic material can inhibit static discharge and further reduce the possibility that the liquid crystal display is damaged by the static discharge.
A packing method of a liquid crystal display using the packing bag comprises the following steps:
A: Putting the liquid crystal display into the packing bag, and zipping up the sealing structure to seal the opening of the packing bag; and
B: Taking out the liquid crystal display from the packing bag for use, recovering the packing bag, and returning to step A.
Preferably, the step A includes:
A1: Clamping the liquid crystal display with antistatic mechanical arms, and putting the liquid crystal display into the packing bag; and
A2: Sealing the sealing structure with the antistatic mechanical arms.
The mechanical arms can improve degree of automation in the packing process and increase productivity. The antistatic mechanical arms can ensure electrostatic prevention in the whole packing process.
The invention uses the sealing structure at the opening of the packing bag to conveniently seal/unseal the opening of the packing bag. Therefore, the packing bag can be circularly reused, and the cost is decreased. The packing bag is sealed by the sealing structure without folding to reduce the material of the packing bag and further decrease the cost.
Wherein: 100. bag body; 200. sealing structure; 210. zipper puller; 211. boss; 221. first chain; 222. male part; 223. second chain; 224. female part.
The invention is further described by figures and the preferred embodiments as follows.
As shown in
As shown in
The sealing structure 200 is provided with two zipper pullers 210; both sides of each of the zipper pullers 210 clamp the outsides of the first chain 221 and the second chain 223; and the middle of each of the zipper pullers 210 is provided with a boss 211 for unsealing the opening. The two zipper pullers 210 are convenient for sealing or unsealing the opening. Both sides of each of the zipper pullers 210 clamp the outsides of the first chain 221 and the second chain 223 to press the male parts 222 into the female parts 224 and realize sealing. The boss 211 is located between the male parts 222 and the female parts 224. When the opening is unsealing, the zipper puller 210 moves in the unsealing direction and the boss 211 can separate the male parts 222 from the female parts 224 to realize unsealing. When a large liquid crystal display is packed, two zipper pullers 210 can move to the canter from both ends of the sealing structure 200 to save the operation time. Also, the packing bag can be provided with one zipper puller to save the cost, and the zipper puller 210 is located at one end of the opening when the opening is sealed. The sealing structure has favorable sealing performance The sealing structure 200 can be made of plastic material, with advantages of certain elasticity and favorable sealing performance, improves the dust and damp prevention effect, and does not easily scratch the liquid crystal display.
Furthermore, the sealing structure is made of antistatic material. Friction between the sealing structure and the packing bag occurs when the liquid crystal display is put into or taken out from the packing bag. The friction causes static discharge. Therefore, the sealing structure made of the antistatic material can inhibit static discharge to further reduce the possibility that the liquid crystal display is damaged by the static discharge.
A packing method of a liquid crystal display using the packing bag comprises the following steps:
A: Putting the liquid crystal display into the packing bag, and zipping up the sealing structure 200 to seal the opening of the packing bag;
