DETAILED DESCRIPTION

[0033] The present invention is now further described in conjunction with the accompanying drawings. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0034] like Figure 2 and Figure 4 As shown, a lithium battery cell and its tray separation device comprises an incoming material conveying line 100, a tray conveying line 200, a cell conveying line 300, a positioning and guiding mechanism 400 and a separation and lifting mechanism 500. The output end of the incoming material conveying line 100 is connected with the input end of the tray conveying line 200, the positioning and guiding mechanism 400 is installed at the input end of the tray conveying line 200, and the cell conveying line 300 is arranged above the tray conveying line 200, and its input end is connected with the output end of the incoming material conveying line 100 through the separation and lifting mechanism 500. The tray carrying the cell is continuously sent by the incoming material conveying line 100, and the separation and lifting mechanism 500 clamps and lifts the cell at the output end of the incoming material conveying line 100, and the positioning and guiding mechanism 400 positions and guides the tray, thereby realizing the automatic separation of the cell and the tray, with a high degree of automation, reducing manual participation, reducing labor costs, ensuring separation quality, and reducing the occurrence of occupational hazards. In addition, the cell conveyor line 300 is arranged above the tray conveyor line 200, which reduces the floor space of the entire device and optimizes the production line layout. Specifically, the incoming material conveyor line 100, the tray conveyor line 200 and the cell conveyor line 300 can be a conveyor belt structure, which is a prior art and will not be described in detail here; the left end (i.e., the input end) of the separation and lifting mechanism 500 is located directly above the output end of the incoming material conveyor line 100.

[0035] like Figure 4 and Figure 5As shown, the positioning guide mechanism 400 includes a guide rail 410 and a guide wheel 420. There are two guide rails 410, which are symmetrically arranged on both sides of the pallet conveyor line 200. There are several guide wheels 420, which are symmetrically arranged on the relatively inner sides of the guide rails 410. The setting of the guide wheels 420 guides the pallet, and at the same time reduces the friction force when the pallet moves due to rolling friction. Specifically, the guide wheels 420 are evenly arranged along the length direction of the guide rails 410, and the guide wheels 420 are in contact with the oblique side surface 2 of the pallet; the guide wheels 420 arranged relatively on the two guide rails 410 form an inverted "eight" shape, thereby preventing the pallet from being lifted up together with the battery cell when the separation lifting mechanism 500 lifts the battery cell and cannot be separated from the battery cell.

[0036] like Figure 2 , Figure 6 , Figure 7 and Fig.11 As shown, the separation and lifting mechanism 500 includes a bracket 510, a lifting component 520, a clamping component 530, a limit component 540 and a distance adjustment component 550. The lifting components 520 are divided into two groups, which are relatively installed in the bracket 510. The left end of the lifting component 520 is connected to the output end of the incoming material conveying line 100, and the right end is connected to the input end of the battery cell conveying line 300. The clamping components 530 are respectively installed on the relatively inner sides of the lifting components 520. The limit components 540 are arranged on the upper and lower sides of the lifting components 520. The distance adjustment components 550 are distributed in the bracket 510 to adjust the distance between the two groups of lifting components 520. When the incoming material conveyor line 100 conveys the pallet carrying the battery cells to the output end of the incoming material conveyor line 100, the two groups of clamping assemblies 530 at the left end of the separation and lifting mechanism 500 clamp the battery cells, and then the lifting assembly 520 drives the clamping assembly 530 to lift. At the beginning of the lifting, the lifting assembly 520 drives the clamping assembly 530 to move to just above the input end of the pallet conveyor line 200. At this time, the positioning and guiding mechanism 400 positions and guides the pallet, and then the lifting assembly 520 continues to drive the clamping assembly 530 to lift, and at the same time the pallet conveyor line 200 continues to convey the pallet, thereby realizing the separation of the battery cells and the pallet.

[0037] like Figure 8 and Fig. 9 As shown, the lifting assembly 520 includes a track 521, a transmission chain 522 and a motor 523. The track 521 is S-shaped, the transmission chain 522 is arranged in the track 521, the motor 523 is installed at the right end of the track 521 to drive the transmission chain 522 to move, and the clamping assembly 530 is installed on the transmission chain 522. The motor 523 drives the clamping assembly 530 to move back and forth along the track 521 through the transmission chain 522, so as to achieve the lifting of the battery cell during separation.

[0038] like Figure 7 and Fig. 9As shown, the clamping assembly 530 includes a clamping jaw 531 and a connecting block 532 , and the clamping jaw 531 is connected to the transmission chain 522 via the connecting block 532 .

[0039] like Figure 6 , Figure 7 , Fig. 9 and Fig.10 As shown, the limiting assembly 540 includes an upper stop bar 541 and a lower stop bar 542, wherein the upper stop bar 541 is arranged on the upper side of the lifting assembly 520, and the lower stop bar 542 is arranged on the lower side of the lifting assembly 520. The setting of the limiting assembly 540 prevents the battery cell from accidentally falling off during the lifting process. Specifically, the limiting assembly 540 is located between the two groups of lifting assemblies 520.

[0040] like Fig.11 and Fig.12 As shown, the distance adjustment component 550 includes a vertical axis 551, a long horizontal axis 552, a short horizontal axis 553, a steering gear 554, a distance adjustment group 555 and a hand wheel 556. The vertical axis 551 is vertically arranged in the bracket 510, the long horizontal axis 552 is transversely arranged in the bracket 510, and its right end is connected to the bottom end of the vertical axis 551 through the steering gear 554, the short horizontal axis 553 is transversely arranged in the bracket 510, and its left end is connected to the top end of the vertical axis 551 through the steering gear 554, the distance adjustment group 555 is composed of several groups, which are distributed on the vertical axis 551, the long horizontal axis 552 and the short horizontal axis 553. The distance adjustment group 555 is installed in the bracket 510, and its driving end is connected to the track 521, and the hand wheel 556 is installed on the right part of the long horizontal axis 552.

[0041] like Fig.12 and Fig.13 As shown, the pitch adjustment group 555 includes a fixed plate 5551, a bidirectional screw rod 5552, a slider 5553 and an adjustment block 5554. The fixed plate 5551 is mounted on the bracket 510. The bidirectional screw rod 5552 is rotatably mounted on the end of the fixed plate 5551 close to the track 521. The slider 5553 is composed of two pieces, which are respectively threadedly sleeved on both ends of the bidirectional screw rod 5552. The slider 5553 is slidably connected to the fixed plate 5551. One end of the adjustment block 5554 is connected to the slider 5553, and the other end thereof is connected to the track 521. Specifically, the bidirectional screw rod 5552 is respectively connected to the vertical shaft 551, the long horizontal shaft 552 and the short horizontal shaft 553 through a bevel gear structure, which is a prior art.

[0042] When the distance of the two groups of lifting components 520 is adjusted, the hand wheel 556 is turned, and the hand wheel 556 drives the long horizontal axis 552 to rotate, and then the vertical axis 551 and the short horizontal axis 553 are synchronously driven to rotate through the two steering gears 554. The rotation of the vertical axis 551, the long horizontal axis 552 and the short horizontal axis 553 respectively synchronously drives the two-way screw rods 5552 connected to each other to rotate. The rotation of the two-way screw rod 5552 drives the two sliding blocks 5553 to move closer to or away from each other, thereby realizing the adjustment of the distance between the two groups of lifting components 520.

[0043] The input end of the tray conveyor line 200 is provided with a photoelectric switch 600 and a reader 700, and both the photoelectric switch 600 and the reader 700 are located on the right side of the positioning guide mechanism 400. Specifically, the photoelectric switch 600 and the reader 700 are both mounted on the bracket 510; the reader 700 is arranged between the photoelectric switches 600. After the tray is separated from the battery cell, the tray conveyor line 200 continues to convey the tray, and after the photoelectric switch 600 detects the tray, the reader 700 reads the tray information to unbind the information.

[0044] During operation, the tray carrying the battery cells is transported from the incoming material conveyor line 100 to the output end of the incoming material conveyor line 100, and then the separation and lifting mechanism 500 clamps the battery cells and lifts them, while the positioning and guiding mechanism 400 positions and guides the tray, thereby achieving separation of the battery cells and the tray.
