Description

Technical Field

[0001] The utility model relates to a Pack tray and a supporting platform used in the automatic production process of lithium batteries. Background Art

[0002] After rapid development and iteration, the domestic lithium battery production industry is moving towards high-level automation, unmanned operation, and flexibility. As a carrier for lithium batteries, trays are widely used and play an important role in the production process of existing lithium battery Pack production lines.

[0003] There are two types of trays in the existing lithium battery Pack production line: standard "grid-shaped" or "channel-shaped" plastic trays for forklifts and non-standard trays with positioning holes for transfer on dedicated conveyor lines. These two types of trays are clearly distinct: First, the "grid-shaped" or "channel-shaped" plastic trays are generally only used to carry raw materials or battery packs for transportation. Slots are provided at the bottom of the trays to cooperate with forklift forks to prevent the trays from falling off the forks. Such trays are common trays widely used by various enterprises and cannot cooperate with equipment on the automatic Pack conveyor line to complete precise installation of parts and battery-related parameter testing. Second, non-standard trays are only used for transfer on the conveyor line to cooperate with equipment and employees on the production line for precise and complex installation and testing. Due to their small friction, they cannot be used on forklifts. In this way, after the forklift transports the plastic tray and the battery pack on it to the side of the conveyor line, the battery pack needs to be placed on the non-standard tray on the conveyor line manually or by a hoist, etc., which is time-consuming and laborious, greatly reducing production efficiency, and at the same time increasing the risk of the battery pack falling during transportation. At the same time, different trays are required for different processes, increasing procurement costs and subsequent maintenance costs.

[0004] In addition, after the battery pack is produced, overall voltage, current, and stability-related tests need to be carried out. Currently, plugs are inserted manually, but the test process even involves high voltages of 800V and above. It is dangerous for employees to operate, and employees need to be professionally trained before they can operate, with high skill requirements.

[0005] Therefore, the trays in the existing automatic production process of lithium batteries no longer meet the production needs, and there is an urgent need for a tray that can be adapted to both the conveyor line and the AGV forklift and can meet the transportation of battery packs for partial high-voltage environment operations.

The anti-skid component is a plurality of anti-skid pads, which are fixed to the bottom surface of the tray body by screws, and the bottom plane of the anti-skid pads is provided with knurling.

[0008] Furthermore, the knurling on the bottom of the anti-slip pad is preferably a reticulated knurling.

[0009] Furthermore, the positioning component includes two pads and four positioning units; the two pads and four positioning units are all fixed on the top of the pallet body, with the pad in the middle and the four positioning units outside the pad to form a square, each positioning unit includes two positioning blocks, and the two positioning blocks form one side of the square.

[0010] Furthermore, a plurality of groups of positioning screw holes are provided on the tray body, and the positioning block is connected to a group of positioning screw holes by screws.

[0011] Furthermore, a plurality of positioning holes are provided on the tray body, and the positioning blocks are connected to the positioning holes via protrusions at the bottom.

[0013] Furthermore, the tray further includes a connecting component, which is a plurality of blind holes provided on the bottom of the tray body.

[0014] Furthermore, the tray also includes a high-life aviation plug female head, which is fixed on the outside of a positioning unit and is connected to the high-voltage and signal interfaces on the battery pack through cables.

[0015] The utility model provides a conveyor line transition platform, which comprises a platform body I and a groove I. The platform body I is provided with the groove I from the outside to the inside. A tray is placed on the platform body, and an anti-slip pad is located in the groove I.

[0016] The utility model provides a testing platform, which comprises a platform body II and a plug-in mechanism. The plug-in mechanism comprises a cylinder and a male plug. The platform body II is provided with a groove II from the outside to the inside. The cylinder is fixed on the platform body II, and the male plug is connected to the telescopic rod of the cylinder.

[0017] The advantages of the pallet of the present invention are: 1. From the transportation of battery packs to the production of conveyor lines to the testing, the uniformity of the fixtures for restraining the battery packs can be achieved through the same pallet, thereby saving the procurement cost of various existing pallets, facilitating later maintenance and thus reducing maintenance costs; 2.

[0042] from Figure 1 、 Figure 2、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 It can be seen that the present invention provides an anti-slip test tray: the tray further includes a connecting component 4, the connecting component 4 is a plurality of positioning hole bushings 41, and the positioning hole bushings 41 are fixed to the bottom of the tray body 1 by screws.

[0043] The pallet is precisely positioned by connecting the positioning bushings on the bottom of the pallet to the positioning posts on the conveyor line to meet the precise positioning requirements of the equipment on the pack conveyor line. At the same time, the pallet is precisely positioned by connecting the positioning bushings on the bottom of the pallet to the positioning posts on the test bench to meet the requirements of testing. Example 8

[0044] from Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 It can be seen that the utility model provides an anti-slip test tray: the tray further includes a connecting component 4 , and the connecting component 4 is a plurality of blind holes arranged on the bottom of the tray body 1 .

[0045] The pallet is connected to the positioning posts on the conveyor line through blind holes on its bottom to achieve accurate positioning, which is used to meet the precise positioning requirements of the equipment on the pack conveyor line. At the same time, the pallet is connected to the positioning posts on the test bench through blind holes on its bottom to achieve accurate positioning to meet the testing requirements. Example 9

[0046] from Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 It can be seen that the present invention provides an anti-skid test tray: the material of the tray body 1 is metal, and the material of the anti-skid pads 31 is metal.

[0047] The pallet body 1 and the anti-skid pad 31 are both made of metal, which can carry heavy goods weighing up to 1 ton and above, and is suitable for occasions with high positioning accuracy.

[0048] from Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6It can be seen that the utility model provides an anti-slip test tray: the tray also includes a high-life aviation plug female head 5, which is fixed on the outside of a positioning unit and is connected to the high-voltage and signal interface 91 on the battery pack 9 through a cable.

[0049] Since the battery packs 9 transported on the pallet need to be tested, and the life of the aviation plug female 5 can reach 100,000 times, the frequency of pallet maintenance is reduced, thus meeting the high-frequency electrical performance testing requirements of the battery pack. Example 11

The pallet is accurately positioned by connecting the connecting component 4 at its bottom to the positioning column on the test platform. At this time, cylinder 72 operates, and its telescopic rod extends to insert male plug 73 into female plug 5, starting the automatic test. When the test is completed, cylinder 72 operates, and its telescopic rod retracts to remove male plug 73 from female plug 5. The forks extend into groove II 74 and remove the pallet from the platform. AGV forklift 6 then transports the pallet to the next workstation.

[0054] This new testing platform requires only the placement of a tray and the battery pack to be tested. A pneumatic cylinder automatically connects and disconnects the male and female connectors for parameter testing of the battery pack, eliminating the need for manual plug insertion.

Furthermore, the plug-in / plug lifespan between the male and female connectors of the aviation plug can reach 100,000 times, meeting the requirements for high-frequency electrical performance testing of battery packs.

[0055] In summary, the pallet of the utility model has been improved in various aspects: First, by adding anti-slip pads at the bottom of the pallet, and the contact surface between the anti-slip pads and the AGV forklift adopts flat knurling to increase friction, the anti-slip of the pallet and the AGV fork is enhanced, so that it can be transported by the AGV forklift; Second, by adding connecting parts at the bottom of the pallet, precise positioning with the conveyor line is achieved to meet the precise positioning requirements of the equipment on the Pack conveyor line; Third, by adding an aviation plug on the upper part of the pallet, the plug-in and unplug life can reach 100,000 times, which can meet the high-frequency electrical performance testing requirements of the battery pack.

[0056] The advantages of the pallet of the present invention are: 1. From the transportation of battery packs to the production of conveyor lines to the testing, the uniformity of the fixtures for restraining the battery packs can be achieved through the same pallet, thereby saving the procurement cost of various existing pallets, facilitating later maintenance and thus reducing maintenance costs; 2. The site for stacking battery packs, conveyor lines, and test platforms are seamlessly connected through a unified pallet, and there is no need to replace different pallets, eliminating the need for elevators or cranes and slings used to transport items on and off the line, saving time and effort, greatly improving production efficiency, and avoiding various safety accidents; 3. The safety factor is greatly improved, avoiding safety hazards during high voltage testing of 800V and above.

[0057] Therefore, the pallet can be transferred between various stations on the assembly line for component assembly and testing, and can be transported to independent high-voltage testing stations outside the assembly line using an AGV forklift. This pallet is suitable for automated lithium battery conveyor lines and the entire production process, achieving a higher degree of automation for the entire line and eliminating the need for human intervention in hazardous testing stations.

[0058] The forklift, conveyor line platform, and test platform mentioned above are several working conditions for the application of anti-slip test pallets. In reality, pallets can be freely matched with other different working conditions to achieve more flexible production. Within the range of pallet compatible product sizes, faster battery pack product changeover speed and lower battery pack product changeover costs can be achieved.
