[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 5 This utility model provides a technical solution: a photovoltaic module pallet palletizing machine, comprising: a support frame 1; a first linear module 2 installed inside the support frame 1 by bolts, and a second linear module 3 installed on the moving slide of the first linear module 2; a bottom adjustment frame 7 installed on the moving slide of the second linear module 3, and a first cylinder 8 installed inside the bottom adjustment frame 7 by bolts; an adjustment support box 9 located at the output end of the first cylinder 8, and a bottom sliding frame 10 symmetrically slidably arranged at the bottom of the adjustment support box 9, and a second cylinder 11 installed inside the bottom sliding frame 10 by bolts; an adjustment support plate 12 fixed to the output end of the second cylinder 11, and a bottom fixing seat 13 installed at the bottom of the adjustment support plate 12 by bolts, an outer mounting seat 15 installed on the outside of the bottom fixing seat 13, and an inner support block 16 symmetrically fixed to one side of the outer mounting seat 15; an inner fixing box 14 installed inside the bottom fixing seat 13 by bolts, and a palletizing positioning plate 26 symmetrically slidably arranged on the inner side of the inner fixing box 14.

[0025] It should be noted that, in this embodiment, after the device is started, the external controller obtains the slide position information of the first linear module 2 and the second linear module 3 in real time through the encoder. Combined with the set vision sensor to identify the tray size and initial position deviation, the adjustment support box 9 is moved to the top of the tray through the X / Y axis linkage of the two linear modules, providing a reference coordinate for subsequent gripping. The first servo motor 20 drives the first bidirectional lead screw 21 to rotate, and through the threaded transmission, the symmetrically arranged first slider 22 slides in opposite directions along the guide rail inside the adjustment support box 9. The bottom of the first slider 22 is fixed to the bottom sliding frame 10, driving it to move synchronously. The sliding cooperation between the first limit rod 23 and the first slider 22 forms a double guide structure to ensure adjustment stability. The first cylinder 8 drives the adjustment support box 9 to press down as a whole, so that the bottom slide... As the moving frame 10 approaches the pallet, the second cylinder 11 drives the adjusting support plate 12 and the bottom fixed seat 13 to move further down, contacting the bottom of the pallet through the outer mounting seat 15 and the inner support block 16. The cylinder end is equipped with a pressure sensor. When the contact force reaches the preset value, the controller automatically stops pressing down to prevent damage to the pallet or photovoltaic modules. The second servo motor 28 drives the second bidirectional lead screw 24 to rotate, and through the threaded transmission, the symmetrically arranged second slider 25 slides along the guide rail in the inner fixed box 14. The bottom fixed seat 13 is slidably connected to the bottom sliding frame 10 through four sets of first limit slide rods 29. The top limit block 4 at the top of the second linear module 3 cooperates with the inner limit rod 5 to improve the stability of the adjustment. When the encoder detects that the servo motor is stalled or the current exceeds the limit, the controller immediately cuts off the power and alarms to avoid damage to the mechanical structure.

[0026] The specific architecture and operation logic of the cylinder, servo motor and linear module in this application to achieve coordinated control through an external controller are consistent with the existing technology in this field. The servo motors used are all equipped with encoders, which can provide real-time feedback on the speed, position and other information of the servo motor. This control method has been maturely applied in many similar industrial scenarios, so it will not be discussed in detail here.

[0027] The linear module includes a bracket for mounting guide rails, a movable slide table that slides on the guide rails, a lead screw system consisting of a lead screw and a nut, and a servo motor that drives the lead screw. The nut is connected to the movable slide table, and the servo motor drives the lead screw to rotate. The lead screw and nut convert the rotation into linear motion, which drives the slide table to move. It is also equipped with a protective cover to protect the internal components from dust and impurities, extend service life, and ensure operating accuracy. The helical motion of the lead screw and nut can convert rotational motion into linear motion, which drives the lead screw to rotate through the servo motor. The lead screw drives the movable slide table to move on the guide rails.

[0028] In one embodiment, such as Figures 3 to 5 As shown, a first bidirectional lead screw 21 is rotatably installed inside the adjusting support box 9. A first slider 22 is symmetrically installed on the outside of the first bidirectional lead screw 21. The first slider 22 is slidably connected to the adjusting support box 9. The bottom of the first slider 22 is fixedly connected to the bottom sliding frame 10. A first servo motor 20 is installed on one side of the adjusting support box 9 by bolts. The output end of the first servo motor 20 is fixedly connected to the first bidirectional lead screw 21. A first limit rod 23 is symmetrically slidably installed inside the first slider 22. The first limit rod 23 is fixedly connected to the adjusting support box 9.

[0029] It should be noted that in this embodiment, the first slider 22 slides to a limit outside the first limiting rod 23, thereby improving the adjustment stability of the first slider 22 and the bottom sliding frame 10 and significantly reducing the risk of stacking skewing.

[0030] In one embodiment, such as Figure 4 and Figure 5 As shown, a second bidirectional lead screw 24 is rotatably installed inside the inner fixed box 14. A second slider 25 is symmetrically installed on the outside of the second bidirectional lead screw 24. The second slider 25 is slidably connected to the inner fixed box 14. One side of the second slider 25 is fixedly connected to the stacking positioning plate 26. A second limiting rod 27 is symmetrically slidably installed inside the second slider 25. The second limiting rod 27 is fixedly connected to the inner fixed box 14. A second servo motor 28 is installed on one side of the inner fixed box 14 by bolts. The output end of the second servo motor 28 is fixedly connected to the second bidirectional lead screw 24.

[0031] It should be noted that in this embodiment, by using the flexible start of the servo motor and the synchronous drive of the bidirectional lead screw, the clamping force fluctuation range of the palletizing positioning plate 26 on the photovoltaic module is controlled within ±5N, thereby reducing the breakage rate. The output end of the second servo motor 28 drives the second bidirectional lead screw 24 to rotate, and the second bidirectional lead screw 24 drives the outer symmetrical second slider 25 to move, thus completing the movement adjustment of the palletizing positioning plate 26.

[0032] In one embodiment, such as Figures 3 to 5 As shown, the inner support block 16 has multiple fixing screws 17 fixed inside, and the bottom fixing seat 13 has multiple limiting mounting holes 18 that cooperate with the fixing screws 17 inside. Two limiting nuts 19 are installed on the outer threads of the fixing screws 17.

[0033] It should be noted that, in this embodiment, the fixing screw 17 inside the outer mounting base 15 passes through the limiting mounting hole 18 opened in the bottom fixing base 13, and then the limiting nut 19 is threaded on the outside of the fixing screw 17, which facilitates the adjustment of the support height of the outer mounting base 15 and the inner support block 16, and also facilitates the replacement of the outer mounting base 15 and the inner support block 16.

[0034] In one embodiment, such as Figures 1 to 5 As shown, four first-position sliding rods 29 are symmetrically fixed to the top of the adjusting support plate 12. The first-position sliding rods 29 are slidably connected to the bottom sliding frame 10. The top of the second linear module 3 is symmetrically fixed to the top of the first-position sliding block 4. The top-position sliding block 4 is slidably connected to the support frame 1. An inner limiting rod 5 is slidably arranged inside the top limiting block 4. Both ends of the inner limiting rod 5 are fixed to the fixing plate 6. The top of the fixing plate 6 is fixed to the support frame 1. The top of the adjusting support box 9 is symmetrically fixed to four second-position sliding rods 30. The second-position sliding rods 30 are slidably connected to the bottom adjusting frame 7.

[0035] It should be noted that in this embodiment, the bottom fixed base 13 is slidably connected to the bottom sliding frame 10 through four sets of first-position limit sliding rods 29, which effectively prevents the photovoltaic module from falling off due to bumps. The top limit block 4 at the top of the second linear module 3 cooperates with the inner limit rod 5 to improve the stability of the movement adjustment.

[0036] In one embodiment, such as Figures 3 to 5 As shown, accordion cloth is installed between slider 22 and adjusting support box 9, and between slider 25 and inner fixed box 14.

[0037] It should be noted that in this embodiment, the accordion cloth blocks dust and impurities, thereby improving the working stability of the lead screw.
