[0029] The following will clearly and completely describe the concept, specific structure and technical effects generated by the present utility model in combination with the embodiments and drawings, so as to fully understand the purpose, features and effects of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, other embodiments obtained by those skilled in the art without creative efforts shall fall within the scope of protection of the present utility model. In addition, all connection / connection relationships involved in the patent do not simply refer to the direct connection of components, but refer to the more optimal connection structure that can be formed by adding or reducing connection accessories according to the specific implementation situation. Each technical feature in the creation of the present utility model can be combined interactively without conflicting with each other.

[0030] Refer to Figure 1 and Figure 2 , a handling cart for an aging plate 4 provided by an example of the present utility model includes a moving cart 1, a support mechanism 2 and a transplanting mechanism 3.

[0031] Among them, the moving cart 1 includes a frame 11 and a first driving member 12 for driving the frame 11 to move.

[0032] Refer to Figure 1 , Figure 5 and Figure 6, Further, the support mechanism 2 is used to carry the aging board 4 and is arranged inside the frame 11. It includes a number of support components 21, and the number of support components 21 are arranged at intervals from top to bottom in sequence. Specifically, the support component 21 includes two first crossbeams 211, a number of support wheels 212 and a number of guide wheels 213. The two first crossbeams 211 are arranged horizontally. The number of support wheels 212 are respectively located on one opposite side of the two first crossbeams 211, and the number of guide wheels 213 are respectively located on the tops of the two first crossbeams 211. The support wheels 212 are used to carry the bottom of the aging board 4 to avoid the phenomenon of the board falling off. The guide wheels 213 are used to limit the side part of the aging board 4 and have a guiding effect. A space for the aging board 4 to be inserted is formed between two adjacent support components 21.

[0033] Specifically, a vertical board 214 is arranged on the side of the frame 11, and a number of first crossbeams 211 are arranged on the vertical board 214 from top to bottom in sequence. Thus, support can be provided for a number of first crossbeams 211.

[0034] More specifically, both the support wheels 212 and the guide wheels 213 are composed of bearings and soft rubber rings sleeved on the outer periphery of the bearings. The soft rubber rings are in contact with the aging board 4. Thus, the aging board 4 can be prevented from being damaged by knocking.

[0035] Refer to Figure 3 and Figure 7 , Even further, the transplanting mechanism 3 is used to transfer the aging board 4 into the support component 21. It includes a moving frame 31, a locking component 32 arranged on the moving frame 31, and a second driving member 33 for driving the moving frame 31 to move along the length direction of the first crossbeam 211. The locking component 32 is used to loosen or lock a number of aging boards 4.

[0036] Specifically, the locking component 32 includes a lifting plate 321, a number of second crossbeams 322 arranged on the lifting plate 321, positioning pins 323 arranged on the second crossbeams 322, and a third driving member 324 for driving the lifting plate 321 to lift and lower. The lifting plate 321 is arranged vertically. The number of second crossbeams 322 are arranged in sequence from top to bottom. The number of second crossbeams 322 correspond to the number of support components 21 one by one. The aging board 4 is provided with positioning pin holes 41. The positioning pins 323 cooperate with the positioning pin holes 41. The lifting plate 321 is slidably connected to the moving frame 31. The third driving member 324 is arranged on the moving frame 31.

[0037] It should be noted that the third driving member 324 is a cylinder.

[0038] During operation, the first driving member 12 drives the frame 11 to move to a specified position. The third driving member 324 drives the lifting plate 321 to rise, and the lifting plate 321 drives a plurality of second cross beams 322 to rise. Then, the second driving member 33 drives the moving frame 31 to move along the length direction of the first cross beam 211 and extend out of the frame 11. The moving frame 31 drives the lifting plate 321 and a plurality of second cross beams 322 to extend out of the frame 11, so that the positioning pins 323 on the second cross beams 322 correspond to the positioning pin holes 41 of the aging plates 4 placed on the multi-layer shelves. Then, the third driving member 324 drives the lifting plate 321 to descend, and the lifting plate 321 drives a plurality of second cross beams 322 to descend, so that the positioning pins 323 on the second cross beams 322 are inserted into the positioning pin holes 41 of the aging plates 4. Next, the second driving member 33 drives the moving frame 31 to move reversely along the length direction of the first cross beam 211 and retract into the frame 11. At this time, a plurality of supporting wheels 212 on the first cross beam 211 respectively support the bottom of the aging plates 4, and a plurality of guiding wheels 213 on the two first cross beams 211 respectively limit the two sides of the aging plates 4, so that a plurality of aging plates 4 respectively enter a plurality of supporting components 21 accurately. Finally, the first driving member 12 drives the frame 11 to move to the next working station. Thus, multiple aging plates 4 can be transferred in batches, greatly improving the working efficiency.

[0039] In some preferred embodiments, a first linear guide rail 34 is provided between the moving frame 31 and the lifting plate 321. The first linear guide rail 34 is vertically arranged, thereby improving the stability of the lifting plate 321 during lifting and ensuring that the positioning pins 323 on the second cross beams 322 can be accurately inserted into the positioning pin holes 41 of the aging plates 4.

[0040] In order to ensure the insertion depth of the positioning pins 323 into the positioning pin holes 41, a proximity switch sensor 312 is provided on the moving frame 31, and an induction block 3211 is provided on the lifting plate 321. The induction block 3211 corresponds to the induction end of the proximity switch sensor 312. When the third driving member 324 drives the lifting plate 321 to descend, the lifting plate 321 drives the induction block 3211 to approach the induction end of the proximity switch sensor 312. When the induction block 3211 contacts the induction end of the proximity switch sensor 312, the third driving member 324 stops operating. Thus, the insertion depth of the positioning pins 323 into the positioning pin holes 41 can be accurately controlled.

[0041] In some preferred embodiments, the second driving member 33 includes a transmission assembly 331 and a first motor 332. The transmission assembly 331 includes a first mounting plate 3311, mounting seats 3312 provided at both ends of the first mounting plate 3311, a lead screw 3313 rotatably connected to the mounting seats 3312, a nut 3314 screwed onto the lead screw 3313, and a nut seat 3314 connected to the nut 3314. The first mounting plate 3311 is provided on the frame 11. The first motor 332 is used to drive the lead screw 3313 to rotate. The nut seat 3314 is connected to the moving frame 31. The length direction of the lead screw 3313 extends along the length direction of the first cross beam 211.

[0042] It can be understood that the first motor 332 drives the lead screw 3313 to rotate. The lead screw 3313 drives the nut 3314 and the nut seat 3314 to move along the length direction of the lead screw 3313. Subsequently, it drives the moving frame 31 to move along the length direction of the lead screw 3313. Thus, the accuracy of the moving frame 31 during movement is improved, ensuring that the positioning pin 323 on the second cross beam 322 can be aligned with the positioning pin hole 41 on the aging plate 4.

[0043] To ensure the stability of the moving seat during movement, the number of transmission assemblies 331 is two. The two transmission assemblies 331 are respectively arranged on the upper and lower sides of the frame 11. The two nut seats 3314 are respectively connected to the upper and lower sides of the moving frame 31. The first motor 332 drives the two lead screws 3313 to rotate simultaneously through a synchronous pulley assembly 333.

[0044] Refer to Figure 4 , specifically, the synchronous pulley assembly 333 includes a first pulley module and a second pulley module. The first pulley module includes a second mounting plate 3331, a rotating shaft 3332 rotatably connected to the second mounting plate 3331, and a first synchronous pulley 3333 provided at one end of the rotating shaft 3332. A second synchronous pulley 3334 is provided on the output shaft of the first motor 332. The output shaft of the first motor 332 is rotatably connected to the second mounting plate 3331. The first synchronous pulley 3333 and the second synchronous pulley 3334 are connected by a first synchronous belt 3335. The second pulley module includes two third synchronous pulleys 3336 and a second synchronous belt 3337 connecting the two third synchronous pulleys 3336. The two third synchronous pulleys 3336 are respectively connected to one end of the two lead screws 3313. One end of the rotating shaft 3332 is connected to one end of one of the lead screws 3313.

[0045] Furthermore, a first tension pulley 3338 and a second tension pulley 3339 are also provided on the second mounting plate 3331. The first tension pulley 3338 is used to adjust the tension of the first synchronous belt 3335, and the second tension pulley 3339 is used to adjust the tension of the second synchronous belt 3337.

[0046] During operation, the first motor 332 drives the second synchronous pulley 3334 to rotate. The second synchronous pulley 3334 drives the first synchronous pulley 3333 to rotate. The first synchronous pulley 3333 drives the rotating shaft 3332 to rotate. The rotating shaft 3332 drives the two third synchronous pulleys 3336 to rotate. The two third synchronous pulleys 3336 simultaneously drive the two lead screws 3313 to rotate. Thus, the upper and lower sides of the moving frame 31 are respectively subjected to forces in the same direction, ensuring the stability of the moving frame 31 during movement.

[0047] Furthermore, a second linear guide 35 is provided between the moving frame 31 and the frame 11. Specifically, second linear guides 35 are provided between the top and bottom of the moving frame 31 and the frame 11, thereby further improving the stability of the moving frame 31 during movement.

[0048] In some preferred embodiments, the first driving member 12 includes a rack (not shown in the figure), a gear 122, and a second motor 123. The rack is provided on the ground. The gear 122 is provided at the output end of the second motor 123. The second motor 123 is provided on the frame 11. The gear 122 meshes with the rack. The second motor 123 drives the gear 122 to rotate, and further drives the frame 11 to move along the length direction of the rack.

[0049] It can be understood that when the gear 122 and the rack are in transmission, the bearing capacity is large and the transmission accuracy is high. Thus, the accuracy of the frame 11 during movement can be improved.

[0050] Furthermore, a third linear guide is provided between the frame 11 and the ground. The length direction of the third linear guide extends along the length direction of the rack, thereby improving the stability of the frame 11 during movement.

[0051] Specifically, the third linear guide includes a slider 13 and a guide rail (not shown in the figure). The slider 13 is provided at the bottom of the frame 11, and the guide rail is provided on the ground.

[0052] In some preferred embodiments, laser obstacle avoidance sensors 111 are provided on both outer sides of the frame 11. When the frame 11 moves, the laser obstacle avoidance sensors 111 can sense obstacles in front. If an obstacle is sensed in front, the second motor 123 stops operating.

[0053] The above is a specific description of the preferred embodiments of the present invention. However, the present invention is not limited to the described embodiments. Those skilled in the art can make various equivalent deformations or substitutions without departing from the spirit of the present invention, and these equivalent deformations or substitutions are all included within the scope defined by the claims of this application.
