[0024] A system for continuous multiple pressing of double-sided adhesive tape for a touch panel, the system comprising: a workbench 3, a carrier 4, a material shifting mechanism and a pressing mechanism, an assembly line 2 is provided on one side of the workbench 3, the carrier 4 is mounted on the table top of the workbench 3, four pressing and positioning jigs 5 are evenly arranged on the carrier 4, the four pressing and positioning jigs 5 are arranged in a straight line, the distance between any two adjacent pressing and positioning jigs 5 is equal, the first of the four pressing and positioning jigs 5 is a loading jig, the last of the four pressing and positioning jigs 5 is a discharging jig, the assembly line 3 is located on the outside of the discharging jig; the pressing mechanism and the material shifting mechanism are arranged on both sides of the carrier 4 relatively, the pressing mechanism 4 comprises a cylinder bracket 6 and a plurality of synchronous pressing cylinders 7, there are three synchronous pressing cylinders 7, all of which are mounted in parallel on the cylinder bracket 6 and are respectively located on the loading Directly above the three pressing and positioning jigs 5 other than the material jig, a pressing mold 704 is provided on the top of the telescopic rod 702 of each synchronous pressing cylinder 7, and when the telescopic rod 702 is extended, the pressing mold 704 can just be pressed on the corresponding pressing and positioning jig 5; the material moving mechanism includes four vacuum suction claws 14, a suction claw seat 13 and a suction claw seat driving structure, and the four vacuum suction claws 14 are all installed in parallel on the suction claw seat 13, and the suction claw seat 13 is installed on the suction claw seat driving structure. The distance between any two adjacent vacuum suction claws 14 is equal to the distance between any two adjacent pressing and positioning jigs 5 and all vacuum suction claws 14 are directly above the carrier 4, and the suction claw seat driving structure can drive the suction claw seat 13 to move vertically up and down and to move back and forth in a straight line parallel to the arrangement direction of the pressing and positioning jig, thereby driving the vacuum suction claw 14 to complete the synchronous grasping and releasing action and the synchronous horizontal position transfer action of the four touch panels.

[0025] Two telescopic rods 702 are provided on each synchronous pressing cylinder body 701, and the top ends of the two telescopic rods 702 are connected by a top block 703, and the pressing mold 704 is fixed on the top block 703. The surface of the pressing mold 704 is covered with a layer of silicone cushion 705, and the hardness of the silicone cushion 705 is between 65 and 75 degrees Shore. By providing the silicone cushion 705, the damage caused by the impact force of the synchronous pressing cylinder 7 on the touch panel 1 due to excessive speed during the pressing process can be effectively reduced, the surface of the touch panel 1 can be prevented from being scratched, and the safety of the pressing action can be improved.

[0026] The object carrier 4 is a frame structure, including an upper frame plate 401 and a lower frame plate 402, wherein the upper frame plate 401 and the lower frame plate 402 are connected via a support column 403, and a positioning column 404 is provided on the surface of the upper frame plate 401 according to the arrangement position of the pressing and positioning fixture 5, and the pressing and positioning fixture 5 is installed on the positioning column 404.

[0027] A touch panel sensor is provided in the middle of the pressing and positioning fixture 5, and the touch panel sensor is electrically connected to the suction claw seat driving structure. In this way, when the touch panel sensors all sense the touch panel 1, the suction claw driving structure will start to drive the suction claw seat to drive the vacuum suction claw to move to complete the grabbing and moving action. If any touch panel sensor does not sense the touch panel 1, the suction claw seat driving structure will not move.

[0028] The suction claw driving structure includes an X-axis driving module, a Y-axis driving module and a base plate 17. The base plate 17 is fixed on the table surface of the workbench 3.

The longitudinal drive cylinder 1201 is installed in the middle of the suction claw bracket 12. Two limit slide bars 1202 are symmetrically installed on both sides of the suction claw bracket 12. The top of the telescopic rod of the longitudinal drive cylinder 1201 and the top of the two limit slide bars 1202 are connected to the suction claw seat 13 at the same time. When the telescopic rod of the longitudinal drive cylinder 1201 is extended and retracted, it can drive the suction claw seat 13 to move vertically up and down as a whole. In this way, the vacuum suction cup 14 can be driven by the drive motor 15 and the longitudinal drive cylinder 1201 to complete longitudinal reciprocating motion and horizontal reciprocating motion, thereby completing the grabbing and moving action of the touch panel.

[0029] A guiding slope 8 is provided between the workbench 3 and the assembly line 2, the top of the guiding slope 8 is connected to the carrier 4, and the bottom of the guiding slope 8 is located in the area directly above the assembly line 2. In this way, when the touch panel 1 is moved from the unloading fixture to the assembly line 1, the guiding slope 8 can prevent the touch panel 1 from falling directly onto the assembly line 2 and causing damage to the touch panel 1 due to a large drop distance, and can also prevent the touch panel 1 from falling between the assembly line 2 and the workbench 3 when moving and being unable to be automatically taken out.

[0030] Two protective gratings 16 are also provided on the workbench 3. The two protective gratings 16 are on the same side as the pressing mechanism. The sensing surfaces of the two protective gratings 16 are respectively located on the front and rear sides of the loading jig, separating the loading jig from the second pressing and positioning jig 5.

[0031] The working principle of this embodiment during lamination is as follows:

[0032] In the first step, the touch panel 1 to be processed is loaded into the loading fixture of the four pressing and positioning fixtures 5. At this time, the touch panel 1 has also been loaded into the other three pressing and positioning fixtures 5.

[0033] In the second step, the driving motor 15 first drives the transmission screw 9 to rotate and drive the four vacuum claws 14 on the claw seat 13 to translate as a whole, so that the four vacuum claws 14 are respectively located directly above the four pressing and positioning fixtures 5, and then the telescopic rod of the longitudinal driving cylinder 1201 is extended to make the vacuum claws 14 grab the touch panel 1 in the corresponding pressing and positioning fixture 5, and the telescopic rod of the longitudinal driving cylinder 1201 is reset to lift the touch panel 1 out of the pressing and positioning fixture 5.

[0034] In the third step, the driving motor 15 drives the transmission screw 9 to rotate and drive the four vacuum suction claws 14 on the suction claw seat 13 to move forward as a whole by a distance between adjacent jigs, so that the touch panel 1 taken out of the discharge jig in the four pressing and positioning jigs 5 reaches above the guide slope 8, and the remaining three touch panels 1 move forward one position respectively, and then the telescopic rod of the longitudinal driving cylinder 1201 is extended so that the touch panel 1 is just placed in the corresponding pressing and positioning jig 5, and the vacuum suction claw 14 is released. At this time, the touch panel 1 taken out of the discharge jig falls into the guide slope 8, and a vacant space appears in the loading jig;

[0035] In the fourth step, the telescopic rod of the longitudinal driving cylinder 1201 is reset, and the driving motor 15 drives the driving screw 9 to rotate and drive the suction claw seat 13 to translate half the distance between adjacent fixtures in the loading direction, so that the vacuum suction claw 14 is just offset from the synchronous pressing cylinder 7, and then the telescopic rods 702 of all the synchronous pressing cylinders 7 are extended to complete the pressing action;

[0036] Step 5: Repeat the contents of Steps 1 to 4 above until all the touch panels 1 to be processed have completed the pressing process.

[0037] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
