Description

Technical Field

[0001] This invention belongs to the field of battery formation equipment technology, specifically relating to a bottom sealing mechanism for power batteries. Background Technology

[0002] On the original formation equipment, the bottom of the power battery did not have a bottom seal. After the battery formation was completed, it was placed in the tray without affecting the bottom of the battery. However, the existing battery has a bottom seal. In order not to damage the bottom seal, the bottom seal of the battery needs to be placed vertically into the tray slot.

[0003] The existing equipment involves a pallet robot grabbing batteries from a pallet, adjusting the battery spacing, and then placing them into the battery scanning area. A water truck robot then grabs the batteries from the scanning area and places them into the water truck. This method suffers from technical problems such as heavy robot arms, slow operating speed, and difficulty in selecting defective batteries. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a power battery bottom sealing mechanism that moves the battery pitch-changing mechanism from the robotic arm to the battery scanning position, improving production efficiency and space utilization; it adds a power battery bottom sealing straightening function; it also adds a battery bottom sealing edge flipping detection function, which is beneficial for selecting defective batteries; and it facilitates battery replacement and enables diversified production.

The support body cylinder (21) is symmetrically arranged on the battery support plate (22). The battery bottom support block (23), the support body clamp (24), and the support body (25) are all mounted on the support body cylinder (21). 1) The battery is placed vertically on the bottom support block (23) of the battery. The driving end of each support body cylinder (21) is driven to be connected to the support body clamp (24). The two support body clamps (24) together form a clamp for clamping the battery. The bottom support block (23) of the battery is located in the middle of the clamp. The support body (25) is installed at the end of the support body clamp (24). The battery baffle (26) is installed on the battery support plate (22) through the battery baffle mounting block (27).

[0008] A bottom sealing assembly (2) is used to straighten the bottom sealing edge of the power battery from a bent state to a vertical state. The bottom sealing assembly (2) includes a pen-shaped cylinder (13), a cylinder mounting plate (14), a gripper cylinder (16), a sealing edge clamp (17), and a sealing edge support body (18). The cylinder mounting plate (14) is mounted on the battery spacing adjustment assembly (3).

The position of the variable pitch guide rail mounting plate (9) on the linear guide rail (8) is changed by the variable pitch cylinder mounting component (10) to adjust the battery spacing.

[0010] The battery barcode scanning component (4) is used to read the battery barcode information and record the status of each battery.

[0011] Battery detection component (5) is used to detect whether there is a battery at the workstation, whether the battery is tilted, and whether the bottom seal of the battery is flipped.

[0012] And the valve island assembly (6) controls the movement of each cylinder through the valve island, so that each cylinder can complete the corresponding action.

The first guide rod mounting part (27) is mounted on the base plate (7) of the barcode scanning platform, and the barcode scanner (28) is detachably mounted on the first guide rod mounting part (27).

The position of the battery baffle (26) in the adjustment hole can be adjusted to accommodate batteries of different sizes.

[0020] The technical concept of this invention is as follows: By setting up a bottom sealing edge assembly, this invention can straighten the bottom sealing edge of the power battery from a bent state to a vertical state, so that when the battery is placed in the tray, the bottom sealing edge can be placed in the groove, preventing the bottom sealing edge of the battery from being bent; by setting up a battery spacing adjustment assembly, the spacing between two batteries can be changed, so that the mechanical book can place the battery into the tray / water cart after picking it up.

[0021] Compared with the prior art, the beneficial effects of the present invention are reflected in:

[0022] 1. Add a function to straighten the bottom edge of the power battery to achieve functional integration.
