Description

Technical Field

[0001] The present application relates to the field of automated adhesive bonding equipment, and in particular to an LCD adhesive bonding machine. Background Art

[0002] In the production and processing steps of LCD displays, the bonding and fixing between the backlight module and the LCD housing is one of the more important processes. The common fixing method is to bond the backlight module and the LCD housing with adhesive.

[0003] The adhesive backing is a long strip of tape, with discontinuity between adjacent adhesive backings. The adhesive backing includes a sticky layer and oil paper. Both sides of the sticky layer are sticky, and the oil paper is set on one side of the sticky layer. During storage or transportation, a release film is usually used. The side of the sticky layer away from the oil paper is adhered to the release film, and then wound on the film supply roll through the release film. When installing the backlight module and LCD housing, the user can separate the adhesive backing from the film supply roll, adhere the adhesive layer of the adhesive backing to a specific position on the surface of the backlight module, and then tear off the oil paper on the surface of the adhesive layer, and adhere the LCD housing through the other side of the adhesive layer.

[0004] Regarding the above-mentioned related technologies, the inventors believe that there are defects such as low production efficiency and high labor costs. Summary of the invention

[0005] In order to improve production efficiency, the present application provides an LCD back glue machine.

[0006] The present application provides an LCD back glue machine, which adopts the following technical solution:

[0007] A LCD adhesive machine comprises a workbench and a workpiece carrier for moving the workpiece, wherein the workbench is provided with an assembly line transport mechanism for placing the workpiece on the workpiece carrier, a back glue feeding mechanism for providing back glue, a back glue laminating mechanism for bonding the back glue to the workpiece, a glue peeling mechanism for separating the adhesive layer from the oil paper, and a carrier transport mechanism for moving the workpiece carrier.

[0008] By adopting the above technical solution, during the production and processing process, the workpiece carrier first waits for the workpiece to be fed, and then the assembly line transportation mechanism transports the workpiece that has completed the previous step to the workpiece carrier, and then the carrier transportation mechanism moves the workpiece carrier to the adhesive bonding mechanism. At the same time, the adhesive feeding mechanism provides the adhesive to be pasted, and the adhesive bonding mechanism takes the adhesive and pastes it on the surface of the workpiece. Then the carrier transportation mechanism moves the workpiece carrier to the glue tearing mechanism, and the glue tearing mechanism can tear off the oil paper on the surface of the adhesive layer to complete the adhesive bonding operation. In the next process, the workpiece can be directly bonded to the LCD shell through the adhesive layer. The LCD adhesive machine can automatically stick the adhesive to the surface of the workpiece, and automatically tear off the oil paper of the adhesive through the adhesive tearing mechanism, eliminating the steps of manual adhesive bonding and manual tearing of oil paper, reducing labor costs and improving production efficiency.

[0009] Optionally, the glue peeling mechanism includes a glue peeling bracket installed on the workbench, a clamping assembly for separating the adhesive layer and the oil paper, and a glue peeling displacement assembly for driving the clamping assembly to move;

[0010] The clamping assembly comprises a pneumatic clamping jaw, and a clamping piece for clamping oil paper is arranged in pairs at the output end of the pneumatic clamping jaw.

[0011] By adopting the above technical solution, the glue tearing bracket supports the glue tearing displacement component, and the pneumatic clamp can clamp the edge of the oil paper through the two clamping parts, and then the pneumatic clamp is driven to move by the glue tearing displacement component to tear the oil paper off the sticky layer.

[0012] Optionally, the clamping member includes a pointed mouth portion for clamping the oil paper, one side of the pointed mouth portion forms a contact surface for contacting the oil paper; a side of the pointed mouth portion away from the abutment surface forms an inclined surface, and the inclined surface gradually inclines in a direction away from the pneumatic clamp and approaching the abutment surface.

[0013] By adopting the above technical solution: the two clamping parts are respectively clamped on the two sides of the oil paper through the abutting surface, thereby driving the oil paper to move away from the sticky layer. When the backing adhesive is attached to the surface of the workpiece, the gap between the oil paper and the workpiece is small, and the inclined surface can reduce the thickness of the tip close to the end of the oil paper, so that the tip is easier to accommodate in the gap between the oil paper and the workpiece.

[0014] Optionally, the abutting surface is provided with a plurality of tooth grooves, each of which is spaced apart along the abutting surface, and teeth for abutting against the oil paper are formed between adjacent tooth grooves.

[0015] By adopting the above technical solution, the teeth can reduce the contact area between the sharp mouth and the oil paper, increase the pressure between the sharp mouth and the oil paper, make the sharp mouth grab the oil paper more stable, and reduce the risk of the oil paper automatically detaching from the sharp mouth during movement. On the other hand, the abutment surface contacts the oil paper through the teeth, reducing the contact area between the sharp mouth and the oil paper, and after the sharp mouth is opened, it is easy for the oil paper to detach from the sharp mouth, reducing the oil paper residue.

[0016] Optionally, the glue tearing displacement assembly includes a glue tearing fixed seat for driving the clamping assembly to move, a glue tearing transmission belt for driving the glue tearing fixed seat to move in a horizontal direction, a glue tearing lifting member for driving the clamping assembly to move in a vertical direction, and a glue tearing driving motor for driving the glue tearing transmission belt to work;

[0017] The glue tearing displacement assembly is arranged on the glue tearing bracket, and the glue tearing lifting member is arranged between the glue tearing fixing seat and the clamping assembly.

[0018] By adopting the above technical solution, in the working state, the glue peeling driving motor drives the glue peeling transmission belt to work, so that the glue peeling transmission belt drives the follower to move, and the follower drives the glue peeling fixed seat to move, so as to realize the horizontal displacement of the clamping assembly. When the clamping assembly moves above the position to be peeled, the glue peeling lifting member can drive the clamping assembly to move downward in the vertical direction, and after the clamping assembly contacts the oil paper, it moves upward to tear the oil paper.

[0019] Optionally, the workpiece carrier is provided with a fixed block, an abutment block for applying force to the workpiece so that the workpiece abuts against the fixed block, and a limiting cylinder for pushing the abutment block; the fixed block and the abutment block are spaced apart and arranged relative to each other so that a limiting space for accommodating the workpiece is formed between the fixed block and the abutment block.

[0020] By adopting the above technical solution, after the workpiece is placed in the limiting space, the limiting cylinder can move the abutment block to make the workpiece abut between the abutment block and the fixed block, so that the workpiece and the workpiece carrier are relatively fixed, reducing the position deviation of the workpiece during movement and improving the position accuracy when the adhesive backing is pasted.

[0021] Optionally, the workpiece carrier is provided with a clearance groove for the pointed mouth to contact the oil paper, and the fixing blocks are arranged on both sides of the clearance groove.

[0022] By adopting the above technical solution, one side of the workpiece abuts against the fixed block, so that the gluing position of the workpiece is close to the clearance groove, and the clearance groove increases the operable space of the sharp mouth, making the action of tearing the oil paper smoother.

[0023] Optionally, the workpiece carrier transport mechanism includes a first transport mechanism and a second transport mechanism that alternately completes processing steps with the first transport mechanism;

[0024] The first transport mechanism includes a first support plate for driving the workpiece carrier to move, a first transport guide rail for guiding the movement of the first support plate, and a first transport drive assembly for driving the first support plate to move; the workbench is provided with a guide rail support plate for raising the first transport guide rail;

[0025] The second transport mechanism includes a second support plate for driving the movement of another workpiece carrier, a second transport guide rail for guiding the movement of the second support plate, a second transport drive assembly for driving the second support plate to move, and a lifting member for driving the second support plate to rise and fall.

[0026] By adopting the above technical solution, the first support plate can support the workpiece carrier, and the first transport drive assembly can drive the first support plate to move along the first transport guide rail, thereby transporting the workpiece carrier; the second support plate can support the workpiece carrier, and the second transport drive assembly can drive the second support plate to move along the second transport guide rail, thereby transporting the workpiece carrier. The first support plate and the second support plate can support different workpiece carriers when working, and the second support plate is always located below the first support plate when moving, so that the first support plate does not interfere with the second support plate when moving. The lifting member can drive the second support plate to rise and fall, so that the workpiece carrier on the second support plate is at a height that can cooperate with the processing equipment.

[0027] Optionally, the adhesive feeding mechanism comprises a peeling bracket installed on the workbench, the workbench is provided with a plurality of feeding stations for the peeling bracket to be installed, and the feeding station is provided with a station base detachably connected to the peeling bracket and a feeding guide rail for supporting the station base;

[0028] The station base is slidably connected to the feeding guide rail, the feeding station is provided with a chassis positioning block, and the station base is provided with a spring latch component for limiting the movement of the station base by engaging with the chassis positioning block.

[0029] By adopting the above technical solution, the user can install the stripping bracket on at least one feeding station according to actual needs. When the stripping bracket is in the working state, the user can make the positioning pin cooperate with the chassis positioning block to fix the stripping bracket relative to the workbench; when the stripping bracket is not in the working state, the user can remove the positioning pin from the chassis positioning block, then move the stripping bracket to a suitable position, and then operate the stripping bracket.
