[0036] The adsorption platform 15 with the upper diaphragm positioned and adsorbed moves in the X and Z axis directions, and the soft support surface 22 moves in the Y axis direction, so that the upper diaphragm and the lower diaphragm are coaxially aligned and continuously approach each other to form a gap arrangement, and then the lifting roller pressing assembly 23 located on the lower bonding platform 2 works, and the lifting roller pressing wheel 43 of the rolling group 4 rises to lift the lower diaphragm located on the soft support surface 22, so that the lower diaphragm continuously approaches the upper diaphragm, and then the rolling group 4 moves laterally to drive the lifting roller pressing wheel 43 to roll and press the lower diaphragm to the bottom surface of the upper diaphragm, and there is a soft support surface 22 between the lifting roller pressing wheel 43 and the lower diaphragm, and the lifting roller pressing wheel 43 will not directly contact the diaphragm, which can reduce the probability of damage, ensure the bonding stability and protect the diaphragm at the same time.

[0037] Specifically, the upper bonding platform 1 includes a bonding gantry 11 arranged horizontally along the X-axis direction, the bonding gantry 11 is provided with a first X-axis linear module 12 along the X-axis direction, the first X-axis linear module 12 is provided with a first Z-axis linear module 13 arranged longitudinally, the first Z-axis linear module 13 is provided with a Z-axis sliding seat 14, an adsorption platform 15 is provided on the Z-axis sliding seat 14, and a plurality of adsorption holes for vacuum adsorption of the upper diaphragm are formed on the bottom surface of the adsorption platform 15.

[0038] The adsorption platform 15 can move in the X-axis direction of the bonding gantry 11 to adsorb the upper film to be bonded, and transfer it to the vicinity of the lower bonding platform 2.

[0039] The lower bonding platform 2 also includes a first Y-axis linear module 16 arranged along the Y-axis direction, and a Y-axis driving seat 17 is installed at the driving end of the first Y-axis linear module 16.

Move the Y-axis driving seat 17 so that the lower film and the upper film located on the soft support surface 22 are close to each other for coaxial alignment and waiting for bonding.

[0040] The laminating box 20 is formed with a driving cavity 21, and the lifting roller pressing assembly 23 also includes a guide rail assembly arranged along the length direction of the driving cavity 21. The rolling group 4 includes a rolling bottom plate 27 installed on the guide rail assembly, and the rolling bottom plate 27 moves along the length direction of the guide rail assembly. The rolling group 4 moves along the length direction of the guide rail assembly, so that the lifting roller pressing wheel 43 installed in the rolling group 4 can roll the lower film to the upper film along the length direction of the guide rail assembly for laminating. The lifting roller pressing wheel 43 will not directly contact the film, which can reduce the probability of damage, ensure the laminating stability and protect the film at the same time.

[0041] Furthermore, a blast hole 28 is provided at the bottom of the bonding box 20, and the blast hole 28 is connected to a blower. Under the blowing of the blower, the soft support surface 22 on the top of the bonding box 20 always remains slightly bulging or flush with the bonding box 20, preventing the soft support surface 22 from being concave and causing deformation of the lower diaphragm.

[0042] Specifically, the guide rail assembly includes a pair of guide rail support plates 24 arranged in parallel and spaced apart, and a guide rail 25 arranged along the length direction of the guide rail support plate 24. The guide rail 25 is slidably mounted with a guide rail sliding seat 26, and a rolling base plate 27 is mounted on the guide rail sliding seat 26. The guide rail sliding seat 26 moves along the length direction of the guide rail 25, and the sliding stability is good. In addition, the design of two parallel and spaced arrangements is adopted, and the rolling base plates 27 are mounted on the two guide rails 25, which further increases the sliding stability and further improves the fitting accuracy.

[0043] The driving chamber 21 is provided with a bottom driving member 3 parallel to the guide rail assembly, and the driving end of the bottom driving member 3 moves along the length direction of the driving chamber 21. The bottom driving member 3 includes a rotatable driving screw 31 and a screw sleeve seat 32 slidably mounted on the driving screw 31, and the screw sleeve seat 32 is connected to the rolling bottom plate 27. When the driving screw 31 rotates, the screw sleeve seat 32 moves along the length direction of the driving screw 31, and the rolling bottom plate 27 connected to the screw sleeve seat 32 moves along the length direction of the driving screw 31 at the same time, so as to realize rolling.

[0044] Specifically, the bottom driving member 3 also includes a servo motor 34 arranged in the driving cavity 21, bearing seats 33 are respectively installed at both ends of the driving screw rod 31, and a transmission synchronous wheel 36 is installed at one end of the driving screw rod 31 through the bearing seat 33. A driving synchronous wheel 35 is installed at the driving end of the servo motor 34, and a synchronous belt 37 is installed between the driving synchronous wheel 35 and the transmission synchronous wheel 36. The servo motor 34 is connected to the transmission synchronous wheel 36 installed on the driving screw rod 31 through the driving synchronous wheel 35. Under the transmission of the synchronous belt 37, the driving screw rod 31 can rotate in the driving cavity 21, ensuring that the rolling group 4 can automatically move back and forth.

[0045] Furthermore, the rolling group 4 also includes a rolling drive plate 41 installed on the rolling base plate 27, and the rolling drive plate 41 is equipped with a pair of spaced drive rollers 42, and a lifting roller pressure wheel 43 is installed on the top of the drive roller 42. The lifting roller pressure wheel 43 and the drive roller 42 roll together, and after the lifting roller pressure wheel 43 presses the lower diaphragm against the upper diaphragm, the lifting roller pressure wheel 43 will roll the lower diaphragm. At the same time, the drive roller 42 rolls at the same time to provide rolling support for the lifting roller pressure wheel 43, thereby improving the rolling stability of the lifting roller pressure wheel 43 and further improving the accuracy of the lamination.

[0046] Preferably, rolling vertical plates 44 are installed at both ends of the rolling drive plate 41, and the driving roller 42 can be rotatably installed between the two rolling vertical plates 44. A semicircular groove 45 is formed on the top of the rolling vertical plate 44 for installing the end of the lifting roller pressure wheel 43. The driving roller 42 is installed on the rolling vertical plate 44 through a bearing member, and both ends of the lifting roller pressure wheel 43 are installed in the semicircular groove 45 through bearing members. The design of the semicircular groove 45 allows the lifting roller pressure wheel 43 to be quickly replaced, so as to adapt to diaphragms of different sizes.

[0047] Furthermore, the rolling bottom plate 27 is installed with a bottom lifting cylinder 46, and the driving end of the bottom lifting cylinder 46 is connected to the rolling driving plate 41. Under the drive of the bottom lifting cylinder 46, the lifting roller 43 installed on the rolling driving plate 41 can push the lower diaphragm against the upper diaphragm, and roll the lower diaphragm to the bottom surface of the upper diaphragm for bonding and covering.

[0048] Preferably, the rolling drive plate 41 is provided with a bottom movable hole for the piston rod of the bottom lifting cylinder 46 to move through, the piston rod is connected to the rolling drive plate 41, the bottom lifting cylinder 46 is installed at the bottom of the rolling base plate 27, the rolling drive plate 41 is provided with a guide shaft 47, the rolling base plate 27 is provided with a guide hole coaxially aligned with the guide shaft 47, a linear bearing sleeve 48 is installed in the guide hole, and a stop sleeve 49 limitedly matched with the linear bearing sleeve 48 is installed at the bottom of the guide shaft 47. When the bottom lifting cylinder 46 drives the rolling base plate 27 to rise and fall, the guide shaft 47 installed on the rolling drive plate 41 slides longitudinally along the linear bearing sleeve 48 installed in the guide hole, thereby ensuring that the lifting roller 43 installed on the rolling drive plate 41 can rise and fall linearly, and when lifting the lower diaphragm, the coaxiality is always maintained, and the upper diaphragm is accurately fitted, thereby improving the fitting accuracy.
