Description

Technical Field

[0001] This utility model relates to the field of turnover cart technology, specifically to a battery module finished product turnover cart. Background Technology

[0002] Currently, in the field of battery module assembly (PACK), when the order quantity is small, in order to save costs, the battery module assembly process (i.e., assembling the cells into battery modules, and welding the battery modules and busbars, etc.) is generally semi-automated. In this case, a transfer trolley is needed to move the transfer tray (specifically, the transfer tray carrying the battery modules) between different workstations. In the prior art, such as patent publication number CN119018218A, a locking and turnover device for the transfer tray and a battery transfer tool are disclosed, including a trolley assembly, a transfer tray assembly, and a self-locking mechanism. The trolley assembly has a transfer tray assembly and a self-locking assembly on its top. The self-locking assembly automatically locks the transfer tray assembly on top of the trolley assembly when the transfer tray assembly moves to the right, and releases the lock when the transfer tray assembly is pushed to the left by the worker. Battery modules are placed on top of the transfer tray (i.e., the item carrier) of the transfer tray assembly. However, the trolley assembly for placing battery modules is only located on top of the trolley assembly. This results in a limited number of battery modules that can be transported per trolley turnaround, which is not conducive to further improving the efficiency of battery module turnover and transportation by the trolley.

[0033] See the example. Figure 1-6 :

[0034] A battery module finished product turnover cart includes a frame 1, with casters at the bottom of the frame 1. Several transfer and placement layers 10 are provided inside the frame 1 for placing battery module products 30 to be transferred. Preferably, the number of casters is four, respectively arranged at the four corners of the bottom of the frame 1. The casters include two omnidirectional brake wheels 11 on one side and two directional wheels 12 on the other side. A handrail is provided on one side of the upper part of the frame 1, and the handrail is located on the same side as the omnidirectional brake wheels 11.

[0035] The transfer and placement layer 10 is provided with at least one set of flow strips 2, each set having two flow strips 2. The flow strips 2 are used to place the battery module trays 3. The flow strips 2 facilitate the entry and exit of the battery module trays 3. In use, the battery module trays 3 are inserted from the front of the flow strips 2, and the battery module trays 3 are placed on the flow strips 2 by pushing them along the arrangement direction of the flow strips 2.

[0036] In one implementation, the number of transfer and placement layers 10 is 3, and each transfer and placement layer 10 is provided with two sets of flow strips 2, so that the frame can rotate 6 battery module trays 3 with battery module products 30 each time.

[0037] The battery module carrier tray 3 is provided with a cushioning urethane rubber 13 on the frame 1 at the rear. When the battery module carrier tray 3 enters the transfer and placement layer 10 along the flow strip 2, the side of the battery module carrier tray 3 touches the cushioning urethane rubber 13, which cushions the battery module carrier tray 3. Each flow strip 2 is provided with a guide strip 4 on both sides. The distance between the two guide strips 4 is greater than the width of the battery module carrier tray 3. The guide strips 4 guide the battery module carrier tray 3.

[0038] In one embodiment, the guide bar 4 is provided with an inclined clearance guide 40 at its front end. The inclined clearance guide 40 is arranged on the side facing the battery module carrier 3, and the thickness of the front side of the inclined clearance guide 40 is less than the thickness of the rear side of the inclined clearance guide 40.

[0039] A transfer channel 20 is set between each pair of flow strips 2. A check valve 5 is set at the front of the transfer channel 20. When the battery module tray 3 enters the transfer placement layer 10 along the flow strip 2, the check valve 5 prevents the battery module tray 3 from flowing back and sliding out of the transfer placement layer 10.

[0040] In one embodiment, the check valve 5 includes a mounting base 50, which is mounted on a locking sheet metal part 51 by a first screw. The locking sheet metal part 51 is mounted on the transfer placement layer 10 by a second screw. The mounting base 50 is provided with a mounting groove 52, and a check block 53 is rotatably mounted in the mounting groove 52. Specifically, the mounting groove 52 and the check block 53 are respectively provided with shaft holes 57, and a rotating shaft 54 ​​passes through the shaft holes 57, so that the check block 53 is rotatably mounted in the mounting groove 52. The upper part of the check block 53 is provided with a triangular protrusion 55, and the lower part of the check block 53 is recessed with a spring mounting hole 56. A return spring is arranged in the spring mounting hole 56, and the lower end of the return spring contacts the bottom of the mounting groove 52. When the battery module tray 3 enters the transfer and placement layer 10 along the flow strip 2, the battery module tray 3 contacts the triangular protrusion 55, causing the check block 53 to press down. After the battery module tray 3 enters the transfer and placement layer 10, under the action of the return spring, the check block 53 rotates upward and pops out, so that the triangular protrusion 55 is stuck on the front side of the battery module tray 3, preventing the battery module tray 3 from slipping out. It can be understood that the top surface height of the mounting base 50 is lower than the top surface height of the flow strip, and after the check block 53 is reset under the action of the return spring, the top surface height of the triangular protrusion 55 is higher than the top surface height of the flow strip.

[0041] The battery module carrier 3 is provided with a plurality of mounting holes 31. Each side of the top surface of the battery module carrier 3 is provided with a mounting hole 31. The battery module limiting block 32 is installed in the mounting hole 31 by a third screw. The battery module limiting block 32 is provided with a mounting waist hole 33 corresponding to the mounting hole 31. The middle of the battery module limiting block 32 is used to place the battery module product 30.

[0042] In one embodiment, transfer handles 34 are provided on both sides of the top surface of the battery module carrier tray 3.

[0043] The battery module carrier plate 3 has a pin mounting hole 35 for mounting the indexing pin 6 on the rear side of the top surface. The indexing pin 6 is located outside the battery module limiting block 32. The transfer channel 20 is provided with a limiting pin hole 21 opposite to the indexing pin 6.

[0044] In one embodiment, the indexing pin 6 includes a pin seat 60 and a limiting pin 63. The pin seat 60 has a through hole 61 extending through its length. The limiting pin 63 is movably inserted into the through hole 61. The top end of the limiting pin 63 is connected to the handle 64. The length of the limiting pin 63 is greater than the length of the pin seat 60. When the battery module tray 3 enters the transfer and placement layer 10, the lower end of the indexing pin 6 is directly opposite the limiting pin hole 21. At this time, the user manually moves the limiting pin 63 downward and inserts it into the limiting pin hole 21, thereby fixing the battery module tray 3 and preventing it from moving.

[0045] In one embodiment, the pin seat 60 is mounted on the pin mounting hole 35 via the lower nut 65. The diameter of the upper part of the pin seat 60 is larger than the diameter of the lower part of the pin seat 60, and the diameter of the lower part of the pin seat 60 is smaller than the diameter of the pin mounting hole 35. The lower part of the pin seat 60 is provided with an external thread corresponding to the lower nut 65. The distance between the external thread and the upper part of the pin seat 60 is the same as the thickness of the battery module carrier plate 3.

[0046] In one embodiment, the upper side wall of the pin seat 60 is provided with a lateral through groove 62 corresponding to the handle 64. The lateral through groove 62 is connected to the through hole 61. The inner diameter of the through hole 61 is larger than the outer diameter of the limiting pin 63, and the outer diameter of the limiting pin 63 is smaller than the diameter of the limiting pin hole 21.

[0047] In one embodiment, the limiting pin hole 21 is arranged on the rear sheet metal part 22, and the rear sheet metal part 22 is installed in the transfer channel 20.

[0048] In practical applications, a double-speed chain lift is arranged on one side of the frame 1. The double-speed chain lift is used to transport the battery module tray 3 containing the battery module product 30. When the battery module tray 3 moves with the double-speed chain lift to the same height as the corresponding transfer and placement layer 10, the user stops the double-speed chain lift and moves the battery module tray 3 into the corresponding transfer and placement layer 10 of the frame 1. When each transfer and placement layer 10 has a battery module tray 3, the user moves the frame 1 to transport the battery module tray 3.

[0049] The foregoing description of the specifications and embodiments is intended to explain the scope of protection of this utility model, but does not constitute a limitation on the scope of protection of this utility model. Modifications, equivalent substitutions, or other improvements to the embodiments of this utility model or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this utility model or the foregoing embodiments, should all be included within the scope of protection of this utility model.
