[0040] The protective film feeding mechanism 20 includes a coil feeding mechanism and a protective film stripping and placing station 21. The width of the protective film stripping and placing station 21 covers two protective films 300. Two rows of cross-spaced circular protective films 300 are arranged in the width direction of the coil. The coil feeding mechanism conveys a single protective film to the protective film stripping and placing station 21 in a stepwise manner.

[0041] A double suction head pick-and-place mechanism 30 is installed on the lower surface of one side of the upper assembly plate 80 relative to the protective film feeding mechanism 50. The double suction head pick-and-place mechanism 30 includes a third guide rail 31. A double suction head device 32 is arranged on the third guide rail 31. Two suction heads 33 of the double suction head device 32 are arranged downward. The two suction heads 33 are respectively used to absorb the corresponding protective film 300. Each suction head 33 is connected to an independent X-direction moving mechanism and a Z-direction moving mechanism. The double suction head device 32 stops at the protective film stripping and placement station 21 and the film attaching station 500 along the third guide rail 31.

[0042] An automatic film tearing mechanism 50 is fixedly installed at one end of the upper assembly plate 80 away from the product feeding mechanism 10.

The input end of the precision module 15 is connected to a first stepping motor 16. The lifting support rod 14 drives the product in the first clip 11 or the second clip 12 to be transported upward in a stepping direction in terms of height.

[0046] Since the protective film 300 is circular and arranged in a stack relative to the center of the product 200, the feeding setting can be quickly switched by rotating the cylinder 13;

[0047] A product height optical sensing device 17 is arranged on the outer periphery of the magazine on the upper part of the lifting support rod 14. When the product height optical sensing device 17 detects that there is no product in the corresponding magazine, the rotary cylinder rotates, the magazine is switched, and the empty magazine is quickly filled with products;

[0048] The coil feeding mechanism 20 includes a protective film feeding mechanism 22, a carrier film receiving mechanism 23, a tensioning assembly 24, a peeling platform 25, and a protective film peeling and placing station 21.

The coil is placed in the feeding mechanism through the protective film feeding mechanism 22, and the material belt passes through the peeling platform 25 and the tensioning assembly 24 and is connected to the carrier film receiving mechanism 23. The tensioning mechanism 24 is tightened and the stepping is started to peel off the protective film 300 and the carrier film. After the protective film 300 is peeled in place, it is placed in the protective film peeling and placing station 21, and the stepping motor 26 stops. After waiting for the double suction head pick-up and placement mechanism to take it away, the stepping motor 26 works again to place the protective film.

[0049] The protective film stripping and placing station 21 is provided with a material placing sensor. When the protective film 300 is placed on the protective film stripping and placing station, the stepping motor 26 stops working and waits until the protective film 300 is sucked away before stepping again.

Each suction head seat 37 is respectively connected to a corresponding linear bidirectional motor 38. The linear bidirectional motor 38 drives the corresponding suction head seat 37 to move in the X direction. Each suction head seat 37 is respectively provided with a Z-direction servo module 39. The lower output end of each group of Z-direction servo modules 39 is connected to a suction head 33. The suction head 33 is specifically an angle adjustment servo suction head, which ensures that the two suction heads are adjusted in the X direction according to the actual interval of the protective film 300, so that the subsequent bonding can be formed in one time.

[0051] The double-Tab mobile transfer mechanism 40 includes two first guide rails 41 arranged in parallel, and two support workbenches 42 arranged on both sides. Each support workbench 42 is respectively embedded in the corresponding first guide rail 41. The two first guide rails 41 are respectively arranged on both sides of the mounting plate 43. Each support workbench 42 is independently arranged with a servo motor module 44. The servo motor module 44 independently drives the corresponding support workbench 42 to move and arrange, so as to ensure that the device can still work normally when a group of support workbenches 42 fails.

[0052] A backlight source 45 is provided at the center of the length direction of the mounting plate 43 corresponding to the attachment position of the two protective films, and a CCD camera (obstructed in the figure, belonging to the existing mature installation technology) is provided at the position corresponding to the film attachment station of the upper assembly plate 80. The CCD camera and the lower convex plate 35 do not interfere with each other, and the CCD camera and the backlight source are used for accurate positioning of attachment;

[0053] The product handling mechanism 60 includes two vacuum suction cups 62 arranged at intervals, each vacuum suction cup 62 is connected to a Z-direction driving mechanism, and the arrangement of the two vacuum suction cups 62 shortens the overall stroke, one vacuum suction cup is used for loading materials, and the other vacuum suction cup is used for outputting finished products, thereby improving production efficiency;

[0054] The automatic film tearing mechanism 50 is installed on the connecting plate 52, and the connecting plate 52 is fixedly connected to the corresponding end of the upper assembly plate 80. One end of the connecting plate 52 is connected to a rodless cylinder 53, and the output end of the rodless cylinder 53 is fixedly connected to a mechanism mounting frame 54. Two spaced-apart film tearing assemblies 51 are arranged at the bottom of the mechanism mounting frame 54. The film tearing assemblies 51 are driven and connected by a servo motor module 55. The rodless cylinder 53 drives the mechanism mounting frame to move horizontally along the precision track 56, which is used to adjust the corresponding working position of the automatic film tearing mechanism 50 after the two supporting workbenches 42 are switched and to transfer the film to the waste box.

[0055] The beneficial effects of the specific embodiments are as follows: the product conveyor is a double-station magazine bin, and material can be changed without stopping the machine; the automatic material feeder automatically sucks after optical fiber sensing, has double suction heads, and has a CCD camera function; the double Tab bonding platform, the vacuum fixture is accurately positioned, has a film tearing function, and is inspected after bonding and automatically sorted.

[0056] Its working principle is as follows: the product feeding mechanism steps the product in the height direction, and at the same time, the protective film roll is stepped onto the protective film. After the double suction head pick-and-place mechanism adjusts the corresponding position to adsorb the two protective films, the distance between the two suction heads is adjusted and moved to the film pasting station. The product handling mechanism automatically transports the product to the supporting workbench of the feeding station of the double Tab mobile transfer mechanism. Then, the supporting workbench of the double Tab mobile transfer mechanism moves to the film pasting station. The double suction head pick-and-place mechanism falls in the Z axis to paste the protective film to the corresponding position of the product. After the double suction heads are in contact and adsorbed, the Z axis rises.
