In addition, if the terms "first", "second", etc. appear, they are only used to distinguish in the description and have no special meaning.

[0045] like Figures 1 to 7 As shown, the pallet conveying device of this embodiment includes a frame 100 , a pallet 200 , a conveying mechanism 300 and a supporting mechanism 400 .

[0046] The rack 100 has a loading position, a conveying position and a unloading position along the conveying direction of the tray 200 , and the loading position and the unloading position are respectively located on both sides of the rack 100 along the X direction.

[0047] The bottom of the tray 200 is provided with a plurality of first clamping assemblies 210 and a plurality of second clamping assemblies 220 spaced apart along the X direction, that is, the plurality of first clamping assemblies 210 are spaced apart along the X direction, and the plurality of second clamping assemblies 220 are spaced apart along the X direction;

[0048] The conveying mechanism 300 includes a positioning assembly 310, a first driving assembly 320 and a second driving assembly 330 arranged on the frame 100. The output end of the first driving assembly 320 is connected to the positioning assembly 310, and the first driving assembly 320 can drive the positioning assembly 310 to move along the Z direction; the output end of the second driving assembly 330 is connected to the first driving assembly 320, and the second driving assembly 330 can drive the first driving assembly 320 and the positioning assembly 310 to move along the X direction, so that the positioning assembly 310 is selectively engaged with the first engaging assembly 210, and the X direction is perpendicular to the Z direction;

[0049] The support mechanism 400 includes a support assembly 410 and a third drive assembly 420 disposed on the frame 100. The output end of the third drive assembly 420 is connected to the support assembly 410. The third drive assembly 420 can drive the support assembly 410 to move along the Z direction, so that the support assembly 410 is selectively engaged with at least one set of second engaging assemblies 220.

[0050] When the support assembly 410 is engaged with the second clamping assembly 220 and the positioning assembly 310 is separated from the first clamping assembly 210, the tray 200 is fixed relative to the positioning assembly 310, and the second drive assembly 330 can drive the positioning assembly 310 to move in the direction toward the upper material position to the bottom of at least another group of first clamping assemblies 210; when the positioning assembly 310 is engaged with the corresponding first clamping assembly 210 and the support assembly 410 is separated from the second clamping assembly 220, the second drive assembly 330 can drive the positioning assembly 310 and the tray 200 to move in the direction toward the lower material position.

[0051] In this embodiment, when the tray 200 is located at the loading position, the second drive assembly 330 drives the positioning assembly 310 to move toward the loading position, so that the positioning assembly 310 is located below a group of first clamping assemblies 210 close to the positioning assembly 310 along the X direction of the tray 200. At this time, the first drive assembly 320 drives the positioning assembly 310 to move upward, so that the positioning assembly 310 is engaged with the group of first clamping assemblies 210, thereby limiting the movement of the tray 200 relative to the positioning assembly 310 in the horizontal direction. The second drive assembly 330 can drive the positioning assembly 310 to drive the tray 200 to move synchronously in the direction toward the unloading position; after this stroke is completed, the tray 200 is located at the conveying position or partially at the conveying position, and the support assembly 410 is located to At least one group of second clamping components 220 is below the third driving member, driving the supporting component 410 to rise and clamp with the corresponding second clamping component 220, the first driving component 320 drives the positioning component 310 to separate from the first clamping component 210, and then the second driving component 330 drives the positioning component 310 to move toward the upper material position, so that the positioning component 310 is located below at least another group of first clamping components 210, the first driving component 320 drives the positioning component 310 to rise and clamp with the corresponding first clamping component 210, at this time, the second driving component 330 can drive the positioning component 310 and the tray 200 to move in the direction toward the lower material position; this cycle is repeated until the tray 200 is completely transported to the lower material position.

[0052] In this embodiment, a first clamping assembly 210 and a second clamping assembly 220 are specially designed at the bottom of the tray 200. Through the coordinated action of the conveying mechanism 300 and the supporting mechanism 400, the tray 200 can be conveyed efficiently and stably, thereby avoiding battery damage caused by accidental collision or falling of the tray 200 during manual handling.

[0053] Furthermore, if Figure 4 and Figure 6 As shown, the positioning assembly 310 includes a positioning plate 311, two first positioning posts 312 and two second positioning posts 313. The output end of the first driving assembly 320 is transmission-connected to the positioning plate 311. The two first positioning posts 312 are located at one end of the positioning plate 311 along the X direction and are adjacent to the loading position. The two second positioning posts 313 are located at the other end of the positioning plate 311 along the X direction and are adjacent to the unloading position. The two first positioning posts 312 are spaced apart along the Y direction, and the two second positioning posts 313 are spaced apart along the Y direction. Figure 5, each group of first clamping components 210 includes two positioning holes spaced apart along the Y direction; the second driving component 330 can drive the positioning plate 311 to drive the two first positioning columns 312 and / or the two second positioning columns 313 to move to the bottom of the positioning holes of one group of first clamping components 210 and engage with the corresponding positioning holes; when the supporting component 410 is engaged with at least one group of second clamping components 220, the first driving component 320 can drive the positioning component 310 to separate from the first clamping component 210, and the second driving component 330 can drive the first positioning column 312 or the second positioning column 313 of the positioning component 310 to move to the bottom of any group of first clamping components 210 of the tray 200; the X direction, the Y direction and the Z direction are perpendicular to each other.

[0054] In this embodiment, the process of dragging the pallet 200 at the loading position into the conveying position mainly relies on the snap-fitting between the first positioning column 312 close to the loading position and the first snap-fitting assembly 210, and is assisted by the driving of the second drive assembly 330 and the snap-fitting between the support assembly 410 and the second snap-fitting assembly 220; and the process of conveying the pallet 200 at the conveying position to the unloading position mainly relies on the snap-fitting between the second positioning column 313 close to the unloading position and the first snap-fitting assembly 210, and is assisted by the driving of the second drive assembly 330 and the snap-fitting between the support assembly 410 and the second snap-fitting assembly 220. Among them, the second driving component 330 drives the positioning component 310 to move back and forth on the frame 100, that is, to move back and forth between the first position (close to the loading position) and the second position (close to the unloading position). When the positioning component 310 moves from the first position to the second position, the tray 200 advances once in the conveying direction, and the distance is the length of a single stroke of the positioning component 310; then the positioning component 310 needs to perform a return operation. Before the positioning component 310 returns, it is separated from the first clamping component 210. After the tray 200 is supported by the supporting component 410, the positioning component 310 returns from the second position to the first position. At this time, another group of positioning holes adjacent to the previously clamped positioning holes is located directly above the first positioning column 312 of the positioning component 310; after the first positioning column 312 is clamped and matched with the positioning hole, the second driving component 330 drives the positioning component 310 to move the tray 200 from the first position to the second position, and the tray 200 advances again in the conveying direction by the distance of a single stroke, and this cycle is repeated until the tray 200 is conveyed to the unloading position.

[0055] Furthermore, the first drive assembly 320 includes a first drive part 321, a first mounting plate 322 and a first guide structure 323 that plays a guiding role along the Z direction. The first mounting plate 322 is located below the positioning plate 311, and the first drive part 321 is installed on the first mounting plate 322. The output end of the first drive part 321 is transmission-connected to the positioning plate 311, and the first mounting plate 322 is transmission-connected to the output end of the second drive assembly 330. The first drive part 321 can drive the positioning plate 311 to move along the Z direction, and the first mounting plate 322 is slidingly connected to the positioning plate 311 through the first guide structure 323.

[0056] It can be understood that when the first driving part 321 drives the positioning plate 311 to move upward along the Z direction, so that the first positioning column 312 and / or the second positioning column 313 are engaged with at least one group of positioning holes, the second driving component 330 can drive the first mounting plate 322 to drive the first driving part 321, the positioning plate 311 and the tray 200 to move along the X direction toward the lower material position; when the first driving part 321 drives the positioning plate 311 to move downward along the Z direction, so that the positioning component 310 is separated from the positioning hole of the first engaging component 210, the second driving component 330 can drive the first mounting plate 322 to drive the first driving part 321 and the positioning plate 311 to move along the X direction toward the upper material position.

[0057] In this embodiment, the first driving part 321 is a cylinder, but not limited to this. In other embodiments, it can also be a driving structure that can realize linear drive, such as a linear motor, a cylinder, etc. Among them, the setting of the first guide structure 323 can improve the stability of the upward and downward movement of the positioning plate 311, so that the first positioning column 312 and / or the second positioning column 313 can be stably engaged with the corresponding positioning hole. Specifically, the first guide structure 323 in this embodiment is two groups, and the two groups of first guide structures 323 are respectively installed on the first mounting plate 322 and are located on both sides of the first driving part 321 along the Y direction. The first guide structure 323 includes two fixed seats, a slide rail, a slide seat and a connecting seat. Two slide rails are respectively installed on one side of the fixed seat along the Y direction. The length of the slide rail extends along the Z direction. The connecting seat is slidably connected to the slide rail through the slide seat, and the top of the connecting seat is fixedly connected to the positioning plate 311.

[0058] Furthermore, the second drive assembly 330 includes a second drive part 331, a second mounting plate 332 and a second guide structure 333 that serves as a guide along the X direction. The second mounting plate 332 is located below the first mounting plate 322. The second drive part 331 is installed on the second mounting plate 332. The output end of the second drive part 331 is transmission-connected to the first mounting plate 322. The second drive part 331 can drive the first mounting plate 322 to move along the X direction. The second mounting plate 332 is slidingly connected to the first mounting plate 322 via the second guide structure 333.

[0059] Among them, the second driving part 331 is selected from a motor, and in other embodiments, a cylinder can also be selected. A cylinder or the like can realize a driving structure of linear drive. By setting a second guide structure 333, the movement stability of the positioning assembly 310 along the X direction can be improved. Specifically, the second guide structure 333 is divided into two groups, and the two groups of second guide structures 333 are fixed on the second mounting plate 332 at intervals along the Y direction. Each group of second guide structures 333 includes a slide rail and a slide seat. The length of the slide rail extends along the X direction. The first mounting plate 322 is slidably connected to the slide rail through the slide seat, and the second driving part 331 is located between the two groups of second guide structures 333.

[0060] In this embodiment, the third drive assembly 420 includes two third drive parts, and the two third drive parts are located on one side of the positioning plate 311 along the Y direction and are installed on the second mounting plate 332 at intervals along the X direction. The support assembly 410 includes two support columns, and the two support columns are respectively connected to the output end of one of the third drive parts in a transmission manner; the second clamping assembly 220 is a support hole arranged at the bottom of the tray 200, and the second drive assembly 330 can drive the positioning assembly 310 to drive the tray 200 to move to at least one group of support holes located directly above the support column, and the third drive part can drive the support column to move along the Z direction so that the support column is clamped and matched with the corresponding support hole.

[0061] Each third driving unit can drive a support column to move up and down along the Z direction. Each time the second driving unit 331 drives the positioning assembly 310 and the tray 200 to move along the X direction toward the material discharge position to a distance of a single stroke, at least one support column is located directly below the corresponding support hole, and the third driving unit can drive the support column to engage with the corresponding support hole to prevent the tray 200 and the positioning assembly 310 from moving together. The third driving unit is selected from a cylinder. In other embodiments, the third driving unit can also be selected from an oil cylinder, a linear motor, etc., which will not be described in detail.

[0062] Furthermore, the first clamping assembly 210 and the second clamping assembly 220 are each in three groups, and one of the positioning holes in each group of the first clamping assembly 210 is arranged adjacent to a supporting hole and located between the two positioning holes; correspondingly, a first positioning column 312 and a second positioning column 313 in the positioning assembly 310 are respectively arranged adjacent to a supporting column, and one of the supporting columns is located between the two first positioning columns 312, and the other support column is located between the two second positioning columns 313.

[0063] It can be understood that, assuming that the tray 200 is located at the loading position, the starting position of the positioning component 310 is located at the first position, and when the positioning component 310 is engaged with the first clamping component 210 at the bottom of the tray 200, the second driving component 330 drives the positioning component 310 and the tray 200 to move together along the X direction toward the direction close to the unloading position. When the positioning component 310 moves from the first position to the second position, half of the length of the tray 200 along the X direction is located at the loading position, and the other half is located at the conveying position; at this time, the supporting component 410 is engaged with the second clamping component 220, and after the positioning component 310 is separated from the tray 200, the positioning component 310 After returning from the second position to the first position and engaging with the first engaging assembly 210 at the bottom of the tray 200, the supporting assembly 410 is separated from the tray 200, and the second driving assembly 330 drives the positioning assembly 310 and the tray 200 to move together along the X direction toward the direction close to the unloading position, that is, from the first position to the second position, the tray 200 moves the distance of a single stroke again, and the tray 200 is located at the conveying position as a whole; the cycle is repeated once again, and half of the length direction of the tray 200 along the X direction is located at the conveying position, and the other half is located at the unloading position; the cycle is repeated once again, and the tray 200 is located at the unloading position as a whole, and the conveying of the tray 200 is completed.

[0064] Furthermore, the conveying mechanism 300 further includes two groups of rolling assemblies 340 mounted on the second mounting plate 332, the two groups of rolling assemblies 340 are respectively located on both sides of the positioning assembly 310 along the Y direction, the supporting mechanism 400 is located between the positioning assembly 310 and one of the groups of rolling assemblies 340, and the third driving assembly 420 can drive the supporting assembly 410 to engage with the second clamping assembly 220 and lift the tray 200, so that the bottom of the tray 200 is at least partially separated from the rolling assembly 340 and the tray 200 is fixed relative to the positioning assembly 310. When the first driving part 321 drives the positioning assembly 310 to separate from the first clamping assembly 210, the second driving part 331 can drive the first mounting plate 322 to drive the first driving part 321 and the positioning plate 311 to move along the X direction; when the supporting assembly 410 is separated from the second clamping assembly 220 and the positioning assembly 310 is clamped with the first clamping assembly 210, the bottom of the tray 200 is in rolling contact with the rolling assembly 340, and the second driving part 331 can drive the first driving assembly 320 to drive the positioning assembly 310 and the tray 200 to move along the X direction.

[0065] By setting the rolling assembly 340, this embodiment can improve the overall movement smoothness of the tray 200 and reduce the energy consumption of the second driving part 331. In addition, the rolling assembly 340 of this embodiment is a passive rolling, that is, the tray 200 rolls with the rolling assembly 340 only when the second driving assembly 330 drives the positioning assembly 310 and the tray 200 to move. Among them, when the first driving assembly 320 drives the positioning assembly 310 to descend, so that the positioning assembly 310 is separated from the tray 200, the clamping cooperation between the support assembly 410 and the second clamping assembly 220 can limit the tray 200 from continuing to roll with the rolling assembly 340 due to inertia.

[0066] Furthermore, the rolling assembly 340 includes a base 341, a substrate 342 and a plurality of rollers 343. The base 341 is fixed on the second mounting plate 332 and is adjacent to one side of the positioning plate 311 along the Y direction. The substrate 342 is fixed on the base 341. The substrate 342 is provided with a plurality of mounting grooves. The rollers 343 are rotatably arranged in the mounting grooves, and the rotation axis of the rollers 343 extends along the Y direction.

[0067] Exemplarily, two groups of mounting grooves are provided on each base plate 342 along the Y direction, and each group of mounting grooves includes a plurality of mounting grooves arranged at intervals along the X direction, and a roller 343 is rotatably installed in each mounting groove. The inner side of the base plate 342 is spaced from the positioning assembly 310, the third driving assembly 420, and the supporting assembly 410 to avoid mutual influence due to contact. Specifically, the base plate 342 is an L-shaped structure, and the two L-shaped base plates 342 are mirror images. When the tray 200 is located above the two base plates 342 and in rolling contact with the roller 343, the side plates of the L-shaped base plate 342 play a role of blocking the outer side of the tray 200.

[0068] like Figure 1 and Figure 7 As shown, the pallet conveying device also includes a fourth drive assembly 500, which is mounted on the frame 100, and the output end of the fourth drive assembly 500 is transmission-connected to the second mounting plate 332, and the fourth drive assembly 500 can drive the second mounting plate 332 to move along the X direction.

[0069] It is understandable that when the size of the device is too large, the overall production cost will increase, and the energy consumption of the corresponding drive mechanism will also increase. In this regard, in order to avoid the length of the support mechanism 400 and the conveying mechanism 300 along the X direction being too long, the fourth drive assembly 500 is added in this embodiment. The fourth drive assembly 500 is installed on the frame 100 and is in transmission connection with the second mounting plate 332, and can drive the second mounting plate 332 and the conveying mechanism 300 and the support mechanism 400 above the second mounting plate 332 to move along the X direction as a whole. Specifically, when the tray 200 is located at the unloading position, the fourth drive assembly 500 first drives the conveying mechanism 300 and the supporting mechanism 400 to move as a whole toward the tray 200, so that the first positioning column 312 of the positioning assembly 310 close to the tray 200 is located directly below a group of positioning holes at the bottom of the tray 200 close to the positioning assembly 310; when the tray 200 is located as a whole above the positioning assembly 310, the fourth drive assembly 500 drives the conveying mechanism 300 and the supporting mechanism 400 to move as a whole toward the unloading position again, and then through the cooperation of the conveying mechanism 300 and the supporting mechanism 400, the tray 200 is transported as a whole to the unloading position through multi-stage transportation.

[0070] In this embodiment, Figure 7 As shown, the fourth driving assembly 500 includes a fourth driving part 510 and a third guiding structure 520 that guides along the X direction. The fourth driving part 510 is installed on the frame 100 and is transmission-connected to the second mounting plate 332. The second mounting plate 332 is slidingly connected to the frame 100 through the third guiding structure 520. The fourth driving part 510 can drive the second mounting plate 332 to move along the X direction.

[0071] Optionally, the fourth driving part 510 is a motor. In other embodiments, a cylinder or an oil cylinder may also be selected. The third guide structure 520 is a way for the slide rail and the slide seat to cooperate with each other, and the details are not repeated. Through the third guide structure 520, the overall movement stability and smoothness of the second mounting plate 332, the conveying mechanism 300 and the supporting mechanism 400 can be improved.

[0072] In this embodiment, Figures 1 to 3 As shown, the frame 100 includes a top bracket 110 and a bottom bracket 120 distributed up and down along the Z direction, two side brackets 130 distributed at intervals along the Y direction, and a bottom plate 140 located on the bottom bracket 120, and the supporting mechanism 400 and the conveying mechanism 300 are both located on the bottom plate 140;

[0074] The fifth drive assembly 600 can drive the bottom plate 140 to drive all the structures installed thereon to move up and down along the Z direction. When the tray 200 is located at the unloading position, the fifth drive assembly 600 can drive the bottom plate 140 to drive the conveying mechanism 300 to descend below the tray 200.

[0075] Among them, the fifth driving assembly 600 includes a fifth driving part 610 and a fourth guiding structure 620 that plays a guiding role along the Z direction. The fifth driving part 610 is installed on the top bracket 110. The output end of the fifth driving part 610 is transmission-connected to the bottom plate 140. The bottom plate 140 is slidingly connected to the side bracket 130 through the fourth guiding structure 620. The fifth driving part 610 can drive the bottom plate 140 to drive the conveying mechanism 300 and the supporting mechanism 400 to move along the Z direction.

[0076] Optionally, the fifth driving unit 610 is a motor with two output ends, each of which is drivingly connected to one side of the bottom plate 140 along the Y direction. Both ends of the bottom plate 140 along the Y direction are slidably connected to the corresponding side bracket 130 through a set of fourth guide structures 620. Specifically, each set of fourth guide structures 620 includes two guide rails and two slide seats, the length of the guide rails extends along the Z direction, the slide seats are fixed on the bottom plate 140, and the guide rails are fixed on the side bracket 130. The bottom plate 140 is guided along the Z direction through the sliding cooperation between the guide rails and the slide seats.

[0077] Furthermore, the pallet conveying device of the present embodiment further comprises a sixth driving assembly 700, the output end of which is transmission-connected to the bottom bracket 120, and the sixth driving assembly 700 can drive the frame 100 to move along the Y direction. When the pallet 200 is fed, the sixth driving assembly 700 first drives the frame 100 as a whole to drive the conveying mechanism 300 and the supporting mechanism 400 to move along the Y direction to the feeding position (loading position) of the pallet 200, and then the fifth driving part 610 drives the bottom plate 140 to drive the conveying mechanism 300 to descend below the pallet 200, and the second driving assembly 330 drives the positioning assembly 310 to move to the first position, so that the first positioning column 312 of the positioning assembly 310 close to the pallet 200 is located directly below a group of positioning holes at the bottom of the pallet 200 close to the positioning assembly 310.

[0078] Furthermore, the sixth drive assembly 700 includes a sixth drive unit 710, a gear transmission structure 720 and a fifth guide structure 730. The sixth drive unit 710 is fixed on an extension portion of the bottom bracket 120 extending to the outside of the side bracket 130. The fifth guide structure 730 includes two slide rails installed on the external bracket 800 at intervals along the X direction and a slide seat slidably matched with the slide rails. The length of the slide rail extends along the Y direction. The slide seat is fixed to the bottom of the bottom bracket 120. The output end of the sixth drive unit 710 is transmission-connected to the external bracket 800 through the gear transmission structure 720. The sixth drive unit 710 can drive the frame 100 to move along the Y direction.

[0079] The sixth driving unit 710 is installed on the extension portion of the bottom bracket 120 extending to the outside of the side bracket 130. Under the action of the gear transmission structure 720 and the fifth guide structure 730, the sixth driving unit 710 can drive the frame 100, the conveying mechanism 300, the supporting mechanism 400 and the sixth driving unit 710 itself to move synchronously along the Y direction.

[0080] Furthermore, the gear transmission structure 720 includes a rack 721 and a gear set. The rack 721 is fixed on the external bracket 800. The length of the rack 721 extends along the Y direction. The gear set is located below the extension part and meshes with the rack 721. The rotation axis of the gear set extends along the Z direction. The gear set is fixedly connected to the output shaft of the sixth driving part 710.

[0081] Since the gear set is meshed with the rack 721 and the gear set is fixedly connected to the output end of the sixth driving unit 710 , the sixth driving unit 710 can drive the gear set to rotate, thereby being able to move along the length direction of the rack 721 .

[0082] Specifically, the gear set includes a first gear 722 and a second gear 723, both of which are located below the extension and mesh with the rack 721, and the rotation axes of the first gear 722 and the second gear 723 extend along the Z direction, and the first gear 722 is fixedly connected to the output shaft of the sixth driving unit 710. By providing two gears, the transmission stability can be improved.

[0083] In this embodiment, Figure 4 and Figure 5, the two support columns are respectively the first support column 411 and the second support column 412, the first support column 411 is adjacent to the first positioning column 312, and the second support column 412 is adjacent to the second positioning column 313; there are three first clamping components 210, along the conveying direction of the pallet 200, the corresponding positioning holes of the three first clamping components 210 are respectively the first positioning hole 211, the second positioning hole 212 and the third positioning hole 213, and the corresponding supporting holes of the three second clamping components 220 are respectively the first supporting hole 221, the second supporting hole 222 and the third supporting hole 223. The working principle of the pallet conveying device of this embodiment is as follows:

[0084] The sixth driving unit 710 controls the frame 100 through the gear transmission structure 720 to drive the conveying mechanism 300 and the supporting mechanism 400 to the material incoming position (loading position) of the tray 200. The fifth driving unit 610 makes the conveying mechanism 300 descend to the lower part of the tray 200 along with the fourth guide structure 620. The fourth driving unit 510 is started to make the conveying mechanism 300 move outward (toward the loading position) along with the third guide structure 520 until the first positioning column 312 is located below the first positioning hole 211 of the tray 200.

[0085] The first driving part 321 is started to make the first positioning post 312 rise and get stuck in the first positioning hole 211 of the tray 200. The second driving part 331 drives the tray 200 to move along the second guide structure 333 and the roller 343 toward the direction of the unloading position until the second support hole 222 is located directly above the first support post 411 through positioning cooperation. The third driving part (third driving assembly 420) drives the first support post 411 to rise and get stuck in the second support hole 222 of the tray 200. The first driving part 321 makes the first positioning post 312 drop away from the first positioning hole 211 to prevent the tray 200 from moving on the roller 343. The second driving part 331 is started to make the positioning plate 311 move toward the loading position until the first positioning post 312 moves to the bottom of the second positioning hole 212 of the tray 200 along the first guide structure 323. The first driving part 321 makes the first positioning post 312 rise and get stuck in the second positioning hole 212. The third driving part is started to make the third driving part (third driving assembly 420) drive the first support post 411 to rise and get stuck in the second support hole 222 of the tray 200. The first support column 411 descends, and the second driving part 331 is started, driving the positioning plate 311 to drive the tray 200 to move along with the second guide structure 333 and the roller 343 toward the direction of the material discharge position until the third support hole 223 moves to the top of the first support column 411. The two third driving parts drive the first support column 411 and the second support column 412 to rise and snap into the corresponding first support hole 221 and the third support hole 223. After the first driving part 321 makes the first positioning column 312 descend, the second driving part 331 drives the positioning plate 311 to move toward the material discharge position until the first positioning column 312 is located directly below the third positioning hole 213, and the second positioning column 313 is located directly below the first positioning hole 211; the first driving part 321 makes the first positioning column 312 rise and snap into the third positioning hole 213, and the second positioning column 313 rise and snap into the first positioning hole 211. At this time, the tray 200 is on the conveying mechanism 300 as a whole (located at the conveying position);

[0086] The fourth driving unit 510 drives the conveying mechanism 300 and the tray 200 to move in the direction of the next material unloading position along with the third guide structure 520, so as to transfer and unload the tray 200; the third driving unit causes the first support column 411 and the second support column 412 to descend, and the second driving unit 331 drives the positioning plate 311 to drive the tray 200 to move in the direction of the material unloading position, so that the second support hole 222 is located directly above the second support column 412; the third driving unit drives the second support column 412 to rise and snap into the second support hole 222 of the tray 200, The first driving part 321 is started to make the first positioning column 312 and the second positioning column 313 descend; the second driving part 331 drives the positioning plate 311 to move in the direction of the upper material position until the second positioning column 313 moves from the third positioning hole 213 to directly below the second positioning hole 212; the first driving part 321 is started to make the second positioning column 313 rise and snap into the second positioning hole 212; the second driving part 331 drives the positioning plate 311 to drive the tray 200 to move in the direction of the lower material position, so that the tray 200 moves as a whole to the lower material position;

[0087] After each mechanism completes its action, it returns to its initial state.
