Description

Technical Field

[0001] This invention relates to the field of battery handling technology, and more particularly to a pallet conveying device. Background Technology

[0002] After the second electrolyte filling of the battery is completed, it needs to be transported to a settling chamber via a conveyor mechanism. The battery will remain in the settling chamber for a period of time before proceeding to the next step. During battery transport, the batteries are typically placed on a tray, and the tray containing the batteries is then moved. Traditional handling methods involve manual handling, which is time-consuming and inefficient; manual handling also carries the risk of accidents, such as battery collisions and damage. Summary of the Invention

Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," etc., are merely used for distinction in description and have no special meaning.

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

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

[0047] The bottom of the tray 200 is provided with a plurality of first snap-fit ​​components 210 and a plurality of second snap-fit ​​components 220 spaced apart along the X direction, that is, the plurality of first snap-fit ​​components 210 are spaced apart along the X direction and the plurality of second snap-fit ​​components 220 are spaced apart along the X direction.

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

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

[0050] When the support component 410 engages with the second snap-fit ​​component 220 and the positioning component 310 is separated from the first snap-fit ​​component 210, the tray 200 is fixed relative to the positioning component 310. The second drive component 330 can drive the positioning component 310 to move along the direction toward the loading position to below at least another set of first snap-fit ​​components 210. When the positioning component 310 engages with the corresponding first snap-fit ​​component 210 and the support component 410 is separated from the second snap-fit ​​component 220, the second drive component 330 can drive the positioning component 310 and the tray 200 to move along the direction toward the unloading position.

[0051] In this embodiment, when the pallet 200 is at the loading position, the second drive component 330 drives the positioning component 310 to move toward the loading position, so that the positioning component 310 is located below a group of first engaging components 210 of the pallet 200 along the X direction near the positioning component 310. At this time, the first drive component 320 drives the positioning component 310 to move upward, so that the positioning component 310 engages with the group of first engaging components 210, thereby restricting the pallet 200 from moving relative to the positioning component 310 in the horizontal direction. The second drive component 330 can drive the positioning component 310 to move the pallet 200 synchronously toward the unloading position. After this stroke is completed, the pallet 200 is located at the conveying position or partially at the conveying position, and the support component 410 is located at the... Below one set of second latching components 220, the third drive component drives the support component 410 to rise and latch with the corresponding second latching component 220. The first drive component 320 drives the positioning component 310 to separate from the first latching component 210. Then, the second drive component 330 drives the positioning component 310 to move towards the loading position, so that the positioning component 310 is located below at least another set of first latching components 210. The first drive component 320 drives the positioning component 310 to rise and latch with the corresponding first latching component 210. At this time, the second drive component 330 can drive the positioning component 310 and the pallet 200 to move together towards the unloading position. This cycle continues until the pallet 200 is completely conveyed to the unloading position.

[0052] In this embodiment, a first snap-fit ​​component 210 and a second snap-fit ​​component 220 are specially designed at the bottom of the pallet 200. Through the coordinated action of the conveying mechanism 300 and the support mechanism 400, the pallet 200 can be conveyed efficiently and stably, avoiding the phenomenon of battery damage caused by accidental collision or drop of the pallet 200 during manual handling.

[0053] Furthermore, such as 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 drive assembly 320 is 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 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 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 5Each set of first snap-fit ​​components 210 includes two positioning holes spaced apart along the Y direction; the second drive component 330 can drive the positioning plate 311 to move the two first positioning posts 312 and / or the two second positioning posts 313 to below the positioning holes of one set of first snap-fit ​​components 210 and engage with the corresponding positioning holes; when the support component 410 engages with at least one set of second snap-fit ​​components 220, the first drive component 320 can drive the positioning component 310 to separate from the first snap-fit ​​component 210, and the second drive component 330 can drive the first positioning post 312 or the second positioning post 313 of the positioning component 310 to move to below any set of first snap-fit ​​components 210 on the tray 200; the X direction, Y direction and Z direction are perpendicular to each other.

[0054] In this embodiment, the process of dragging the pallet 200 from the loading position into the conveying position mainly relies on the engagement of the first positioning post 312 near the loading position with the first locking component 210, and is further assisted by the driving of the second driving component 330 and the engagement of the support component 410 with the second locking component 220; while the process of conveying the pallet 200 from the conveying position to the unloading position mainly relies on the engagement of the second positioning post 313 near the unloading position with the first locking component 210, and is further assisted by the driving of the second driving component 330 and the engagement of the support component 410 with the second locking component 220. In this system, the second drive assembly 330 drives the positioning assembly 310 to move back and forth on the frame 100 in a fixed manner, i.e., it moves back and forth between the first position (near the loading position) and the second position (near the unloading position). When the positioning assembly 310 moves from the first position to the second position, the pallet 200 advances once along the conveying direction, and the distance is the length of a single stroke of the positioning assembly 310. Subsequently, the positioning assembly 310 needs to perform a return operation. Before returning, the positioning assembly 310 separates from the first snap-fit ​​assembly 210. After the pallet 200 is supported by the support assembly 410, the positioning assembly 310 returns from the second position to the first position. At this time, another set of positioning holes adjacent to the previously snap-fit ​​positioning hole is located directly above the first positioning post 312 of the positioning assembly 310. After the first positioning post 312 snaps into the positioning hole, the second drive assembly 330 drives the positioning assembly 310 to move the pallet 200 from the first position to the second position. The pallet 200 then advances once again along the conveying direction, and this cycle continues until the pallet 200 is conveyed to the unloading position.

[0055] Furthermore, the first drive assembly 320 includes a first drive unit 321, a first mounting plate 322, and a first guide structure 323 that guides along the Z direction. The first mounting plate 322 is located below the positioning plate 311. The first drive unit 321 is mounted on the first mounting plate 322. The output end of the first drive unit 321 is connected to the positioning plate 311 in a transmission connection. The first mounting plate 322 is connected to the output end of the second drive assembly 330 in a transmission connection. The first drive unit 321 can drive the positioning plate 311 to move along the Z direction. The first mounting plate 322 is slidably connected to the positioning plate 311 through the first guide structure 323.

[0056] Understandably, when the first drive unit 321 drives the positioning plate 311 to move upward in the Z direction, so that the first positioning post 312 and / or the second positioning post 313 engage with at least one set of positioning holes, the second drive assembly 330 can drive the first mounting plate 322 to move together the first drive unit 321, the positioning plate 311 and the tray 200 in the X direction toward the unloading position; when the first drive unit 321 drives the positioning plate 311 to move downward in the Z direction, so that the positioning assembly 310 separates from the positioning hole of the first engaging assembly 210, the second drive assembly 330 can drive the first mounting plate 322 to move together the first drive unit 321 and the positioning plate 311 in the X direction toward the loading position.

[0057] In this embodiment, the first drive unit 321 is a cylinder, but it is not limited to this. In other embodiments, it can also be a linear motor, hydraulic cylinder, or other drive structure capable of linear drive. The first guide structure 323 improves the stability of the vertical movement of the positioning plate 311, ensuring stable engagement between the first positioning post 312 and / or the second positioning post 313 and the corresponding positioning hole. Specifically, in this embodiment, there are two sets of first guide structures 323, each mounted on the first mounting plate 322 and located on both sides of the first drive unit 321 along the Y direction. Each first guide structure 323 includes two fixed seats, slide rails, a slide block, and a connecting seat. Two slide rails are mounted on one side of the fixed seat along the Y direction, and the length of the slide rails extends along the Z direction. The connecting seat is slidably connected to the slide rails via the slide block, 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 unit 331, a second mounting plate 332, and a second guide structure 333 that guides along the X direction. The second mounting plate 332 is located below the first mounting plate 322. The second drive unit 331 is mounted on the second mounting plate 332. The output end of the second drive unit 331 is connected to the first mounting plate 322 in a transmission manner. The second drive unit 331 can drive the first mounting plate 322 to move along the X direction. The second mounting plate 332 is slidably connected to the first mounting plate 322 through the second guide structure 333.

[0059] In this embodiment, the second drive unit 331 is selected from an electric motor; in other embodiments, a hydraulic cylinder may also be selected. A cylinder or similar device can achieve a linear drive structure. By providing a second guide structure 333, the movement stability of the positioning component 310 along the X direction can be improved. Specifically, there are two sets of second guide structures 333, which are fixed at intervals along the Y direction on the second mounting plate 332. Each set of second guide structures 333 includes a slide rail and a slide block. The length of the slide rail extends along the X direction. The first mounting plate 322 is slidably connected to the slide rail via the slide block. The second drive unit 331 is located between the two sets of second guide structures 333.

[0060] In this embodiment, the third drive assembly 420 includes two third drive units, which are located on one side of the positioning plate 311 along the Y direction and are spaced apart on the second mounting plate 332 along the X direction. The support assembly 410 includes two support columns, which are respectively connected to the output end of one of the third drive units. The second snap-fit ​​assembly 220 is a support hole provided at the bottom of the tray 200. The second drive assembly 330 can drive the positioning assembly 310 to move the tray 200 to a position where at least one set of support holes is directly above the support columns. The third drive unit can drive the support columns to move along the Z direction so that the support columns snap-fit ​​with the corresponding support holes.

[0061] Each third drive unit can drive a support column to move up and down along the Z direction. Each time the second drive unit 331 moves the positioning component 310 and the pallet 200 along the X direction towards the unloading position to the distance of a single stroke, at least one support column is located directly below the corresponding support hole. The third drive unit can then drive the support column to engage with the corresponding support hole, preventing the pallet 200 from moving together with the positioning component 310. The third drive unit is selected from a cylinder; in other embodiments, the third drive unit can also be selected from a hydraulic cylinder, linear motor, etc., which will not be elaborated further.

[0062] Furthermore, the first snap-fit ​​assembly 210 and the second snap-fit ​​assembly 220 are each in three sets. In each set of the first snap-fit ​​assembly 210, one of the positioning holes is adjacent to one of the support holes and located between the two positioning holes. Correspondingly, in the positioning assembly 310, one of the first positioning posts 312 and one of the second positioning posts 313 are respectively adjacent to one of the support posts, and one of the support posts is located between the two first positioning posts 312, and the other support post is located between the two second positioning posts 313.

[0063] Understandably, assuming the pallet 200 is located at the loading position and the positioning component 310 is initially in the first position, when the positioning component 310 engages with the first engaging component 210 at the bottom of the pallet 200, the second drive component 330 drives the positioning component 310 and the pallet 200 together to move along the X direction toward the unloading position. When the positioning component 310 moves from the first position to the second position, half of the length of the pallet 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 support component 410 engages with the second engaging component 220, and after the positioning component 310 separates from the pallet 200, the positioning component 310... After returning from the second position to the first position and engaging with the first engaging component 210 at the bottom of the pallet 200, the support component 410 separates from the pallet 200. The second drive component 330 then drives the positioning component 310 and the pallet 200 together to move along the X direction toward the direction closer to the unloading position, i.e., from the first position to the second position. The pallet 200 moves the distance of a single stroke again, at which point the entire pallet 200 is located in the conveying position. The cycle repeats once more, with half of the pallet 200 along its length in the X direction located in the conveying position and the other half in the unloading position. The cycle repeats again, with the entire pallet 200 located in the unloading position, thus completing the conveying of the pallet 200.

[0064] Furthermore, the conveying mechanism 300 also includes two sets of rolling assemblies 340 mounted on the second mounting plate 332. The two sets of rolling assemblies 340 are respectively located on both sides of the positioning assembly 310 along the Y direction. The support mechanism 400 is located between the positioning assembly 310 and one of the rolling assemblies 340. The third drive assembly 420 can drive the support assembly 410 to engage with the second snap-fit ​​assembly 220 and lift the pallet 200, so that at least part of the bottom of the pallet 200 is separated from the rolling assemblies 340 and the pallet 200 is fixed relative to the positioning assembly 310. When the first drive unit 321 drives the positioning component 310 to separate from the first snap-fit ​​component 210, the second drive unit 331 can drive the first mounting plate 322 to move the first drive unit 321 and the positioning plate 311 along the X direction; when the support component 410 separates from the second snap-fit ​​component 220 and the positioning component 310 snaps into the first snap-fit ​​component 210, the bottom of the tray 200 rolls into contact with the rolling component 340, and the second drive unit 331 can drive the first drive component 320 to move the positioning component 310 and the tray 200 along the X direction.

[0065] This embodiment improves the overall smoothness of the tray 200's movement and reduces the energy consumption of the second drive unit 331 by incorporating the rolling component 340. Furthermore, the rolling component 340 in this embodiment is passively rolling; that is, the tray 200 only rolls into contact with the rolling component 340 when the second drive component 330 drives the positioning component 310 and the tray 200 to move. Specifically, when the first drive component 320 drives the positioning component 310 to descend, separating the positioning component 310 from the tray 200, the engaging action of the support component 410 and the second engaging component 220 prevents the tray 200 from continuing to roll with the rolling component 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 adjacent to the positioning plate 311 on one side along the Y direction. The substrate 342 is fixed on the base 341 and has a plurality of mounting grooves. The rollers 343 are rotatably disposed in the mounting grooves, and the rotation axis of the rollers 343 extends along the Y direction.

[0067] For example, each substrate 342 has two sets of mounting slots along the Y direction, and each set of mounting slots includes multiple spaced mounting slots along the X direction. A roller 343 is rotatably mounted in each mounting slot. The inner side of the substrate 342 is spaced apart from the positioning component 310, the third driving component 420, and the support component 410 to avoid mutual interference due to contact. Specifically, the substrate 342 has an L-shaped structure, and the two L-shaped substrates 342 are mirror images of each other. When the tray 200 is located above the two substrates 342 and rolls in contact with the roller 343, the side plates of the L-shaped substrates 342 act as a stop for 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. The output end of the fourth drive assembly 500 is connected to the second mounting plate 332 in a transmission manner, and the fourth drive assembly 500 can drive the second mounting plate 332 to move in the X direction.

[0069] It is understandable that when the equipment size is too large, the overall production cost will increase, and the energy consumption of the corresponding drive mechanism will also increase. In this embodiment, to avoid the support mechanism 400 and the conveying mechanism 300 being too long in the X direction, a fourth drive assembly 500 is added. The fourth drive assembly 500 is mounted on the frame 100 and is connected to the second mounting plate 332 for transmission, 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 as a whole in the X direction. Specifically, when the pallet 200 is in the unloading position, the fourth drive component 500 first drives the conveying mechanism 300 and the support mechanism 400 to move towards the pallet 200 as a whole, so that the first positioning post 312 of the positioning component 310 near the pallet 200 is located directly below a set of positioning holes near the positioning component 310 at the bottom of the pallet 200; when the pallet 200 is above the positioning component 310, the fourth drive component 500 again drives the conveying mechanism 300 and the support mechanism 400 to move towards the unloading position as a whole, and then through the cooperation of the conveying mechanism 300 and the support mechanism 400, the pallet 200 is conveyed to the unloading position through multi-stage conveying.

[0070] In this embodiment, as Figure 7 As shown, the fourth drive assembly 500 includes a fourth drive unit 510 and a third guide structure 520 that guides along the X direction. The fourth drive unit 510 is mounted on the frame 100 and is connected to the second mounting plate 332 in a transmission manner. The second mounting plate 332 is slidably connected to the frame 100 through the third guide structure 520. The fourth drive unit 510 can drive the second mounting plate 332 to move along the X direction.

[0071] Optionally, the fourth drive unit 510 is a motor; in other embodiments, a cylinder or hydraulic cylinder may also be selected. The third guide structure 520 is a combination of a slide rail and a slide block, the specifics of which will not be elaborated further. The third guide structure 520 can improve the overall movement stability and smoothness of the second mounting plate 332, the conveying mechanism 300, and the support mechanism 400.

[0072] In this embodiment, as Figures 1 to 3 As shown, the frame 100 includes a top support 110 and a bottom support 120 distributed vertically along the Z direction, two side supports 130 distributed at intervals along the Y direction, and a base plate 140 located on the bottom support 120. The support mechanism 400 and the conveying mechanism 300 are both located on the base plate 140.

[0073] The pallet conveying device also includes a fifth drive assembly 600, which is mounted on the top support 110. The output end of the fifth drive assembly 600 is connected to the base plate 140. The fifth drive assembly 600 can drive the base plate 140 to move the conveying mechanism 300 and the support mechanism 400 along the Z direction.

[0074] The fifth drive assembly 600 can drive the base plate 140 to move all the structures mounted on it up and down along the Z direction. When the pallet 200 is in the unloading position, the fifth drive assembly 600 can drive the base plate 140 to lower the conveyor mechanism 300 below the material arriving at the pallet 200.

[0075] The fifth drive assembly 600 includes a fifth drive unit 610 and a fourth guide structure 620 that guides along the Z direction. The fifth drive unit 610 is mounted on the top bracket 110, and the output end of the fifth drive unit 610 is connected to the base plate 140. The base plate 140 is slidably connected to the side bracket 130 through the fourth guide structure 620. The fifth drive unit 610 can drive the base plate 140 to move the conveying mechanism 300 and the support mechanism 400 along the Z direction.

[0076] Optionally, the fifth drive unit 610 is a motor with two output ends, each output end being drively connected to one side of the base plate 140 along the Y direction. The two ends of the base plate 140 along the Y direction are slidably connected to the corresponding side brackets 130 via a set of fourth guide structures 620. Specifically, each set of fourth guide structures 620 includes two guide rails and two slides. The guide rails extend along the Z direction, the slides are fixed to the base plate 140, and the guide rails are fixed to the side brackets 130. The sliding engagement between the guide rails and the slides guides the base plate 140 along the Z direction.

[0077] Furthermore, the pallet conveying device in this embodiment also includes a sixth drive assembly 700. The output end of the sixth drive assembly 700 is connected to the bottom support 120 in a transmission manner. The sixth drive assembly 700 can drive the frame 100 to move along the Y direction. When the pallet 200 is receiving material, the sixth drive assembly 700 first drives the frame 100 as a whole to move the conveying mechanism 300 and the support mechanism 400 along the Y direction to the material receiving position (loading position) of the pallet 200. Then, the fifth drive unit 610 drives the bottom plate 140 to lower the conveying mechanism 300 to below the material receiving position of the pallet 200. The second drive assembly 330 then drives the positioning assembly 310 to move to the first position, so that the first positioning post 312 of the positioning assembly 310 near the pallet 200 is located directly below a set of positioning holes near the positioning assembly 310 at the bottom of the pallet 200.

[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 to the extension of the bottom bracket 120 extending to the outside of the side bracket 130. The fifth guide structure 730 includes two slide rails spaced apart along the X direction and mounted on the outer bracket 800, and a slide block that slides with the slide rails. The length of the slide rails extends along the Y direction, and the slide block is fixed to the bottom of the bottom bracket 120. The output end of the sixth drive unit 710 is connected to the outer bracket 800 through the gear transmission structure 720. The sixth drive unit 710 is capable of driving the frame 100 to move along the Y direction.

[0079] The sixth drive unit 710 is mounted on the extension 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 drive unit 710 can drive the frame 100, the conveying mechanism 300, the support mechanism 400 and the sixth drive 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 and meshes with the rack 721. The rotation axes of the gear set all extend along the Z direction. The gear set is fixedly connected to the output shaft of the sixth drive unit 710.

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

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

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

[0084] The sixth drive unit 710 controls the frame 100 to drive the conveying mechanism 300 and the support mechanism 400 to the material receiving position (loading position) of the pallet 200 through the gear transmission structure 720. The fifth drive unit 610 causes the conveying mechanism 300 to descend with the fourth guide structure 620 to below the material receiving position of the pallet 200. The fourth drive unit 510 starts to move the conveying mechanism 300 outward (towards the loading position) with the third guide structure 520 until the first positioning post 312 is located below the first positioning hole 211 of the pallet 200.

[0085] The first drive unit 321 activates, causing the first positioning post 312 to rise and engage with the first positioning hole 211 of the pallet 200. The second drive unit 331, through positioning engagement, drives the pallet 200, along with the second guide structure 333 and rollers 343, to move towards the unloading position until the second support hole 222 is directly above the first support post 411. The third drive unit (third drive assembly 420) drives the first support post 411 to rise and engage with the second support hole 222 of the pallet 200. The first drive unit 321 causes the first positioning post 312 to descend and leave the first positioning hole 211, preventing the pallet 200 from moving on the rollers 343. The second drive unit 331 activates, causing the positioning plate 311 to move towards the loading position until the first positioning post 312, along with the first guide structure 323, moves below the second positioning hole 212 of the pallet 200. The first drive unit 321 then causes the first positioning post 312 to rise and engage with the second positioning hole 212. The third drive unit activates, causing the first support post 312 to rise and engage with the second positioning hole 212. When the first support column 411 descends, the second drive unit 331 is activated, driving the positioning plate 311 to move the pallet 200 towards the unloading position along with the second guide structure 333 and the roller 343, until the third support hole 223 moves directly above the first support column 411. The two third drive units drive the first support column 411 and the second support column 412 to rise and engage in the corresponding first support hole 221 and third support hole 223. After the first drive unit 321 lowers the first positioning column 312, the second drive unit 331 drives the positioning plate 311 to move towards the unloading position until the first positioning column 312 is directly below the third positioning hole 213 and the second positioning column 313 is directly below the first positioning hole 211. The first drive unit 321 then drives the first positioning column 312 to rise and engage in the third positioning hole 213 and the second positioning column 313 to rise and engage in the first positioning hole 211. At this time, the entire pallet 200 is on the conveying mechanism 300 (located in the conveying position).

[0086] The fourth drive unit 510 drives the conveying mechanism 300 and the pallet 200 to move in the direction of the third guide structure 520 toward the next unloading position, thus transferring and unloading the pallet 200; the third drive unit causes the first support column 411 and the second support column 412 to descend, and the second drive unit 331 drives the positioning plate 311 to move the pallet 200 toward the unloading position, so that the second support hole 222 is located directly above the second support column 412; the third drive unit drives the second support column 412 to rise and engage with the second support hole 222 of the pallet 200. The first drive unit 321 is activated, causing the first positioning post 312 and the second positioning post 313 to descend; the second drive unit 331 drives the positioning plate 311 to move toward the loading position until the second positioning post 313 moves from the third positioning hole 213 to directly below the second positioning hole 212; the first drive unit 321 is activated, causing the second positioning post 313 to rise and engage with the second positioning hole 212; the second drive unit 331 drives the positioning plate 311 to move the pallet 200 toward the unloading position, causing the entire pallet 200 to move to the unloading position;

[0087] After each unit completes its actions, it returns to its initial state.

[0088] The pallet conveyor in this embodiment adopts a multi-stage conveying method, which can efficiently and automatically complete the material conveying, significantly shorten the transportation time, and improve efficiency. Through automated operation, the risks of manual handling and transportation are reduced, and work safety is improved. During operation, the pallet conveyor can reduce collisions and losses during material conveying, thus ensuring material safety.
