Description

Technical Field

[0001] The present invention relates to the technical field of hot pressing and laminating, and more particularly to an automatic hot pressing transfer and laminating integrated device. Background Art

[0002] The main equipment for light guide plates is a hot press, which is used to perform heat transfer operations to complete the important step of light guide plate processing. It is necessary to perform a lamination operation after hot pressing transfer on the entire part to protect the entire part.

[0003] According to existing references, the invention patent with patent publication number CN114872432B discloses that the feeding mechanism and conveying mechanism designed by the invention can cooperate to achieve the alignment of the plate, preventing the plate from deflecting during placement. The designed conveying mechanism has an alignment component that can assist in aligning the plate to prevent the plate from deflecting during transportation. The alignment component is controlled by a curved track and a motor, which can be raised to assist in aligning the plate when in use and lowered to avoid affecting maintenance and loading when not in use. The rotating cutting component of the designed laminating mechanism can press the film during cutting to prevent the film from being damaged due to cutting. At the same time, the rotating cutting component can trim and compact the edge of the plate to improve the quality of lamination.

[0004] According to the above-mentioned laminating device, the entire part needs to be laminated after hot pressing and then cut. In this way, only the parts can be laminated one by one during the laminating process, and batch multi-directional cutting cannot be achieved during cutting. The overall processing efficiency is low, which is not conducive to efficient lamination. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an automated hot pressing transfer and laminating integrated device.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: an automated hot pressing transfer and laminating integrated device, comprising a collar-linked support plate, one side of which is provided with a film-laying roller and a film-collecting roller arranged equidistantly from left to right, and one end of each of the film-collecting roller and the film-laying roller is provided with a laminating mechanism;

[0007] The laminating and coating mechanism includes a servo reduction motor fixedly connected to one end of the film-collecting roller, an upper limit screw ring is threadedly connected to the outer wall of the film-discharging roller and away from the position of the ring linkage support plate, a rectangular guide frame is installed on one side of the ring linkage support plate and near the middle position thereof, and a sleeve ring block is connected to the interior of the rectangular guide frame, a guide pillar with a sliding connection is inserted through the interior of the sleeve ring block, a linkage spring is fixedly connected to the outer wall of the guide pillar and on the upper surface of the sleeve ring block, and a cutting assembly is provided at the middle position between the film-collecting roller and the film-discharging roller.

[0008] Preferably, the sleeve ring block slides vertically along the inside of the rectangular guide frame plate, and the inner wall of the rectangular guide frame plate and the outer wall of the sleeve ring block are polished and ground. The output ends of the two film-releasing rollers are rotatably connected to the sleeve ring linkage support plate through bearings, and the sleeve ring linkage support plate is made of stainless steel.

[0009] Preferably, a linkage push rod is installed on the lower surface of the sleeve ring block and at a position on one side of the outer wall of the guide pillar, and a pushing cylinder is coaxially fixed to the bottom end of the linkage push rod. A conveyor belt is installed below the film-releasing roller, and a driving motor is coaxially fixed to a rotating shaft inside the conveyor belt. A sliding support ring frame is mounted on the output end of the driving motor, and a control button is fixed on one side of the support ring frame.

[0010] Preferably, the cutting assembly includes a central lower cutter arranged at the middle position between the film-collecting roller and the film-discharging roller, and connecting blocks are connected to both sides of the central lower cutter, and side lower cutters are provided on opposite sides of the two connecting blocks. A downward pressure cylinder for vertically pushing the central lower cutter is welded on the upper surface of the central lower cutter, and the pushing end of the downward pressure cylinder is provided with a slidingly connected L-shaped ring bracket. The lower surfaces of the central lower cutter and the side lower cutters are both chamfered and polished.

[0011] Preferably, the connecting support blocks are respectively welded and fixed to the side lower cutters and the middle lower cutter, and the side lower cutters and the middle lower cutter are both made of stainless steel.

[0012] Preferably, a leveling limit assembly is installed on one side of the side lower cutter, and the leveling limit assembly includes a leveling roller installed on one side of the side lower cutter, and a linkage support rod is rotatably connected to the inside of the leveling roller through a bearing, and a threaded ring bracket for downward movement is welded to one end of the linkage support rod, and a threaded transmission screw is inserted into the inside of the threaded ring bracket, and a servo drive motor is coaxially fixed to the top of the transmission screw. A heating box is installed on one side of the outer wall of the film placing roller, and a group of resistance heating rods for heating the film are fixed on the inner wall of the heating box at equal distances from left to right, and guide rollers rotatably connected to the heating box are provided on both sides of a group of resistance heating rods.

[0013] The technical effects and advantages of the present invention are as follows:

[0014] 1. The present invention adopts a laminating mechanism. Under the action of the extrusion and rebound force of the linkage spring, the sleeve ring block drives the sleeve ring linkage support plate to move downward along the inner wall of the rectangular guide frame plate, and the entire film can be laminated to the upper surface of the part for a limited laminating operation. Then the servo reduction motor is started to drive the film-releasing roller to rotate the film, and the other film-releasing roller drives the film-rewinding roller to rewind the film. In this way, the film can be automatically laminated to the upper surface of the part for laminating and feeding, forming a continuous laminating process with higher laminating efficiency.

[0015] 2. The present invention uses a cutting assembly to position three parts equidistantly below two side lower cutters and one middle lower cutter. Then, the downward pressure cylinder can be activated to drive the middle lower cutter to move downward, and the supporting block drives the side lower cutters to move downward. The middle lower cutter and the two side lower cutters cut downward on the edge of the parts, achieving edge-fitting cutting, making the cutting smoother and more efficient.

[0016] 3. The present invention adopts a flat limiting component to place the film cylinder at the outer position of the film placing roller, and the limiting screw ring and the film placing roller are rotated to limit the film cylinder under the action of the thread, and the servo drive motor is started to drive the transmission screw to rotate. The transmission screw drives the threaded collar bracket to drive the linkage support rod downward under the action of the thread, and the flat roller can be squeezed on the film, so that the film moves downward and is parallel to the film on the film placing roller, and parallel lamination avoids bubbles. Moreover, the same angle of limited lamination can be achieved in batches, and the film lamination is more uniform, avoiding rework and repair caused by bubbles, thereby improving processing efficiency.

[0017] In summary, through the mutual influence of the above-mentioned multiple effects, the film can be automatically bonded to the upper surface of the part for bonding and feeding, forming a continuous coating, achieving edge bonding and cutting, making the cutting smoother, and the coating more uniform, avoiding bubbles that cause rework and repair, and effectively improving the efficiency of transfer coating.
