Therefore, they cannot be understood as limitations on the present invention.
[0021] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "installation" and the like should be understood in a broad sense, for example, it can be a fixed connection, a direct connection, or a connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.
[0023] The specific embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.
[0024] An embodiment of the present invention provides a layout system for battery production line assembly to baking, which can satisfy the need for multiple assembly lines to correspond to one baking line. Figure 1 and Figure 2 ,as follows: The battery cell at the unloading port of the first assembly line mechanism moves from right to left through the roller pull line 1 to the vicinity of the ferry platform 2. The ferry platform 2 reads the incoming material information, and the movable pull line inside the ferry platform 2 moves to the roller pull line 1 of the first assembly line. The interface is automatically docked, and the battery cell moves from the roller pull line 1 to the ferry platform pull line. When the battery cell moves to the leftmost end of the ferry platform pull line, the cylinder blocker 7 on the ferry platform and the assembly line is activated to prevent the battery cell from continuing to move to the left and leaving the ferry platform and to prevent the assembly line from continuing to load. After the ferry platform pull line is filled with batteries, it moves to the vicinity of the baking loading position 4 and automatically docks with the baking loading position 4. The cylinder blocker 7 is closed, and the battery cell on the pull line inside the ferry platform 2 moves from right to left to the baking loading position 4. The ferry platform 2 completes the transportation of a battery cell and waits for the next material call.
[0025] It should be noted that the internal pull line of the ferry platform, the roller pull line of the assembly line, and the baking loading position are all equipped with cylinder blockers to prevent the battery cells from continuing to move and falling off the pull line. Figure 2 At the arrow point, the cylinder blocker structure is as follows Figure 5 shown.
[0026] It should be noted that the ferry platform adopts the existing mechanism that can realize the pull-belt line transportation, see Figure 3 and Figure 4 In one embodiment of the present invention, the ferry platform includes a transverse linear module and an upper roller pull belt conveyor line. The roller pull belt conveyor line is driven by a motor. The pull belt is designed with a four-channel separation mechanism, which can ferry and convey 4 battery cells at a time. The ferry platform is a pull belt line that repeatedly returns at high speed to pick up materials. When multiple assembly line pull belts are fed at the same time, the ferry platform picks up the materials in order from top to bottom. When the ferry platform is docked with an assembly line, the cylinder blockers on the remaining assembly lines are activated, stop moving, and wait for material to be received. When the ferry platform is full of battery cells, the cylinder blockers on the ferry platform and the assembly line are activated to prevent the battery cells from falling off and to stop the assembly line from continuing to load materials.
[0027] The battery cell at the unloading port of the second assembly line mechanism moves from right to left through the roller pull line 2 8. After passing through the rotating table 1 3, the battery cell moves from bottom to top on the roller pull line. After passing through the rotating table 2 9, the battery cell moves from left to right on the roller pull line and moves to the vicinity of the ferry platform 2. The ferry platform 2 reads the incoming material information, and the movable pull line inside the ferry platform moves to the roller pull line 2 of the second assembly line. The interface is automatically docked, and the battery cell moves from the roller pull line 2 8 to the ferry platform pull line. The cylinder blocker 7 on the assembly line pull line is activated to prevent the battery cell from continuing to move to the right and leaving the ferry platform. After the ferry platform belt line is filled with batteries, it moves to the vicinity of the baking loading position 4 and automatically docks with the baking loading position 4. The cylinder blocker 7 is closed, and the battery cell on the pull line inside the ferry platform 2 moves from right to left to the baking loading position 4. The ferry platform 2 completes the transportation of a battery cell and waits for the next material call.
[0028] The layout of the fourth and other multiple assembly lines is exactly the same as that of the second assembly line. The multiple assembly lines transport the battery cells back and forth to the baking loading table through the movement of the internal movable belt line in the ferry platform, realizing the situation where multiple assembly lines correspond to one baking line.
[0029] The second embodiment of the present invention provides a baking feeding control method based on the above layout system, and the specific implementation process is as follows: The six-axis manipulator 5 grabs four battery cells from the baking loading position 4 and puts them into the baking tray 10. When the baking tray 10 is full of battery cells, the baking loading robot 11 grabs the baking tray 10 and sends it into the corresponding oven through the ground rail.
[0030] It should be noted that if the gripper grabs a full battery cell at one time, the six-axis manipulator 5 directly places the four full battery cells on the gripper into the baking tray 10 in sequence; if the gripper grabs a less than full battery cell at one time, the six-axis manipulator 5 places the less than full battery cell on the gripper into the pairing tray 6. Figure 6 , the pairing tray has 8 battery cell positions, see Figure 7 .
[0031] The logic of pairing plate 6 placement is as follows: For ease of understanding, see Figure 7The six-axis manipulator 5 is a pairing tray, and the four positions of the six-axis manipulator for grabbing the cells are numbered 1, 2, 3, and 4 from left to right in sequence, and the eight positions of the cells on the pairing tray are numbered 1 to 8 from left to right in sequence. Assuming that the first grab is an empty cell at position 3, the six-axis manipulator 5 first places the cells 1 and 2 on the gripper correspondingly into the positions 1 and 2 of the pairing tray 6, and then places the cell 4 on the gripper into the position 3 of the pairing tray 6. After placement, the six-axis manipulator 5 continues to grab cells from the baking loading table 4, grabs 4 cells again, and if the gripper grabs 4 cells at a time, the six-axis manipulator 5 directly places the 4 cells on the gripper into the baking tray 10 in sequence. If the gripper grabs less than 4 cells at a time, assuming that the second grab, positions 1 and 3 on the gripper are empty cells, and positions 2 and 4 have cells, the six-axis manipulator 5 first puts the cell at position 2 on the gripper into position 4 on the pairing tray 6, and then puts the cell at position 4 on the gripper into position 5 on the pairing tray 6. When there are 4 consecutive cells on the pairing tray 6, the six-axis manipulator 5 grabs the 4 consecutive cells on the pairing tray 6 and puts them into the baking tray 10 at one time. At this time, there is only cell 5 on the pairing tray 6, and the above steps are continued to fill cells 6, 7, and 8 in sequence. If there are still cells on the gripper when filling cell 8, continue to fill them from 1 in sequence. The next time you grab the unfilled cells and put them into the pairing tray 6, you need to first grab the four consecutive cells from 5 to 8 and put them into the baking tray 10, and then continue to grab the unfilled cells and fill them into the pairing tray 6. According to this logic, the six-axis manipulator 5 repeatedly grabs and stores between the baking loading table 4, the pairing plate 6, and the baking tray 10. When the baking tray 10 is full of cells, the baking loading robot 11 grabs the baking tray 10 and sends it into the corresponding oven through the ground rail.
[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the present invention can still be modified or replaced by equivalents. Any modification or equivalent replacement that does not depart from the spirit and scope of the present invention should be covered within the scope of protection of the claims of the present invention.
