[0002] Solar photovoltaic modules are widely used as a new energy source. During the production process, glass sheets are typically used as the carrier for the thin-film solar cell modules. The incoming glass sheets are typically stacked. Before they are added to the photovoltaic module production line, the packaging structure surrounding the stacked glass sheets must be removed.

[0003] Currently, there is a type of stacked glass sheet incoming material. Each incoming material unit contains two stacking units. Plastic-steel belts are installed on the outer periphery of the incoming material unit to bundle the two stacking units together.

[0043] Example 1:

[0044] Please refer to Figures 1-12 The present embodiment is an automatic unpacking production line 100 for photovoltaic module glass, which includes a conveyor line 1, a glass loading station, a glass tray station, an outer layer wrapping film removal station, a strapping tape and wood slat removal station, and a glass unloading station sequentially arranged along the conveyor line 1; the glass tray station is provided with a tray unpacking unit 2, the outer layer wrapping film removal station is provided with an outer layer wrapping film removal unit 3, and the strapping tape and wood slat removal station is provided with a strapping tape and wood slat removal unit 4; the glass loading station is provided with a correction mechanism 5 for correcting the position of a whole tray of incoming glass and a scanning gun 6 for identifying material information; the glass unloading station is provided with a second tray lifting mechanism 7 for lifting a single tray of glass on the conveyor line 1.

[0045] The correction mechanism 5 includes a plurality of correction modules 51 arranged on the left and right sides of the conveyor line 1. The correction module 51 includes a servo electric cylinder 511 and a correction plate 512 driven by the servo electric cylinder 511 to perform telescopic movement.

[0046] The scanning gun 6 is arranged at the front end of the conveyor line 1. The incoming glass is a double-support glass plate, which is taken out from the unloading platform by a forklift 8 and moved to the glass loading station, and then placed on the conveyor line 1.

[0047] The tray unpacking unit 2 is mainly used to split the incoming glass materials of multi-tray glass plates into single-tray stacking units. It includes a first tray lifting mechanism 21 located on the left and right sides of the conveyor line 1, a strapping recovery mechanism 22 located on the left side of the conveyor line 1, and a strapping cutting mechanism 23 located on the right side of the conveyor line 1.

[0048] The number and location of the strapping cutting mechanisms 23 correspond to the location and number of strapping tapes around the incoming double-tray glass stock. In this embodiment, two strapping tapes are provided around the incoming double-tray glass stock. Therefore, two strapping cutting mechanisms 23 are provided, located on the front and rear sides of the first palletizing and lifting mechanism 21. The strapping cutting mechanisms 23 include a first motor 231, a first support plate 232 driven by the first motor 231 for forward and backward movement, a second motor 233 fixed to the first support plate 232, and a first pneumatic shear 234 driven by the second motor 233 for left and right movement. The strapping cutting mechanisms 23 are used to cut the strapping tape around the incoming double-tray glass stock before the first palletizing and lifting mechanism 21 performs the palletizing operation, allowing the first palletizing and lifting mechanism 21 to separate the multiple stacking units. The front and rear positions of the first pneumatic shear 234 can be adjusted by the configuration of the first motor 231, thereby meeting the strapping tape cutting requirements at various locations and improving the versatility of the production line.

[0049] The strapping tape recovery mechanism 22 is mainly used to pull out and recycle the strapping tape after it is cut off from the outer periphery of the double-support glass incoming material. The strapping tape recovery mechanism 22 is arranged opposite to the strapping tape cutting mechanism 23 on the left and right, and the number and position of the two are corresponding. One strapping tape cutting mechanism 23 is configured with one strapping tape recovery mechanism 22. In this embodiment, the strapping tape recovery mechanism 22 is provided with two, respectively located on the front and rear sides of the first tray lifting mechanism 21, and includes a first recovery bin 221, a recovery and feeding module 222 arranged on one side of the top of the first recovery bin 221, a first pulling and recovery module 223 that moves horizontally in the space above the first recovery bin 221 and clamps and pulls the strapping tape from the outer periphery of the double-support glass incoming material to above the first recovery bin 221, and a first visual camera 224 that obtains the position of the strapping tape on the periphery of the double-support glass incoming material.

[0050] The recovery and feeding module 222 includes a pair of feed rollers 2221 facing each other vertically, and a first cylinder 2222 that drives the feed rollers 2221 up and down to achieve opening and clamping motions. The first cylinder 2222 drives the two feed rollers 2221 to switch between an open state and a clamping state. In the open state, the first pulling and recovery module 223 extends to clamp the cut strapping tape, straightening it above the first recovery bin 221. The feed rollers 2221 then switch to a clamping state. The rotation of the feed rollers 2221 transports the strapping tape toward the first recovery bin 221, ultimately delivering all the strapping tape to the first recovery bin 221, thereby achieving strapping tape recovery. In this embodiment, to achieve the rotational motion of the feed rollers 2221, the feed rollers 2221 are motorized rollers.

[0051] The first material recovery module 223 is primarily used to straighten the strapping tape cut from the outer periphery of the incoming double-panel glass material above the first recovery bin 221. It comprises an XYZ transfer module 2231 positioned above the first recovery bin 221, a second support plate 2232 positioned at the movable end of the XYZ transfer module 2231, and a first clamping jaw 2233 mounted on the second support plate 2232. When the two feed rollers 2221 are open, the second support plate 2232, with the first clamping jaw 2233, can pass through the space between the two feed rollers 2221 to clamp the strapping tape. Before clamping the cut strapping tape, the first material recovery module 223 uses a first vision camera 224 to identify the strapping tape's position. The XYZ transfer module 2231 then drives the first clamping jaw 2233 into position based on the strapping tape's position, ensuring that the first clamping jaw 2233 accurately grasps the strapping tape.

[0052] The outer layer stretch film removal unit 3 is mainly used to remove the stretch film on the outer periphery of the single-pallet stacking unit, and includes several film cutting modules 31 arranged near the four corners of the stacking unit, a second recovery bin 32 located next to the conveyor line 1, a stretch film adsorption module 33 above the conveyor line 1 that adsorbs the stretch film and moves to the side of the second recovery bin 32, and a second material pulling recovery module 34 in the second recovery bin 32 that moves horizontally above the second recovery bin 32 and clamps and straightens the stretch film on the stretch film adsorption module 33.

[0053] The film cutting module 31 includes a first bracket 311, a third motor 312 mounted on the first bracket 311 and capable of adjusting its front-to-back position, a third support plate 313 driven by the third motor 312 for vertical movement, and a film cutting assembly 314 mounted on the third support plate 313 and capable of adjusting its left-to-right position. The film cutting assembly 314 can be a hot air gun or a blade. If a blade is used, the blade is configured with a horizontal movement function, such as a cylinder mounted on the third support plate 313 to drive the blade toward or away from the palletizing unit, allowing the blade to switch between a working position and a standby position. By making the third motor 312 adjustable in front-to-back position, the front-to-back position of the film cutting assembly 314 can be flexibly adjusted according to the size of the glass sheets in the palletizing unit. Furthermore, by making the film cutting assembly 314 adjustable in left-to-right position, it can also be adapted to palletizing units of various sizes. The third motor 312 drives the film cutting assembly 314 to move up and down, cutting the stretch film from top to bottom or from bottom to top, so that the stretch film adsorption module 33 can smoothly remove the stretch film from the periphery of the stacking unit.

[0054] The stretch film suction module 33 includes a fourth motor 331, a fourth support plate 332 driven by the fourth motor 331 to move left and right above the conveyor line 1, a second cylinder 333 fixed to the fourth support plate 332, a second bracket 334 driven by the second cylinder 333 to move up and down, and a plurality of suction cups 335 mounted on the second bracket 334. The stretch film suction module 33 absorbs the stretch film that has been cut from the outer periphery of the palletizing unit and then moves it horizontally to the side and above the second recovery bin 32 to remove the stretch film.

[0055] The second material recovery module 34 includes a fifth motor 341, a fifth support plate 342 driven by the fifth motor 341 to move left and right above the second recovery bin 32, and a second clamping jaw 343 secured to the fifth support plate 342. After the stretch film suction module 33 absorbs the stretch film that has been cut from the outer periphery of the palletizing unit and moves it horizontally to the side and above the second recovery bin 32, the second material recovery module 34 grasps the stretch film on the suction cup 335 at the far left and moves to the right, pulling the entire stretch film straight into the second recovery bin 32, completing the stretch film recovery process.

[0056] In other embodiments, the transfer range of the stretch film adsorption module 33 may be directly extended to above the second recovery bin 32 to achieve the release and recovery of the stretch film, and the second material recovery module 34 may be eliminated.

[0057] The strapping strip removal unit 4 primarily cuts and removes the strapping tape around the outer perimeter of the single-pallet stacking unit, as well as the protective strips. For some stacking units covered with an inner layer of wrapping film, the unit also cuts and removes the inner wrapping film. The strapping strip removal unit 4 includes a robot 41 located adjacent to the conveyor line 1, with its working range covering the entire strapping strip removal station; a shearing and clamping mechanism 42 located at the movable end of the robot 41; strip fixing mechanisms 43 located on the left and right sides of the conveyor line 1 to secure and compress the protective strips on the exterior of the stacking unit; and third and fourth recovery bins 44, 45 located adjacent to the robot 41. The third recovery bin 44 is used to recycle strapping tape, and the fourth recovery bin 45 is used to recycle protective strips.

[0058] The shearing and clamping mechanism 42 includes a sixth support plate 421 fixed to the movable end of the robot 41 , a second visual camera 422 fixed to the sixth support plate 421 , a wood slat clamping module 423 , a second pneumatic scissors 424 and a strap clamping module 425 .

[0059] The second visual camera 422 is used to obtain the positions of the strapping tape and the protective wooden slats on the palletizing unit.

[0060] The number and position of the slat fixing mechanisms 43 correspond to the number and position of the protective slats on the stacking unit. In this embodiment, the slat fixing mechanisms 43 include a third cylinder 431 and a pressing plate 432 that is moved left and right by the third cylinder 431 and presses the protective slats.

[0061] In this embodiment, a rail-type conveyor trolley 11 is provided at the tail section of the conveyor line 1. The rail-type conveyor trolley 11 reciprocates between the strapping and wood slat removal station and the glass unloading station. After the single-tray palletizing unit is completed at the strapping and wood slat removal station, it is moved to the glass unloading station by the rail-type conveyor trolley 11. The single-tray palletizing unit is then lifted by the second-tray lifting mechanism 7, and the rail-type conveyor trolley 11 returns to the strapping and wood slat removal station. The AGV trolley 9 moves to the glass unloading station, and the second-tray lifting mechanism 7 descends, placing the palletizing unit onto the AGV trolley 9, which is then transported to the photovoltaic module production line.

[0062] The structure of the second support-dividing lifting mechanism 7 is the same as that of the first support-dividing lifting mechanism 21 .
