Description

Technical Field

[0001] This invention relates to a positioning fixture, and more particularly to a precision positioning fixture for preventing short circuits in battery cells, belonging to the field of soft-pack battery technology. Background Technology

[0002] Battery cells are classified into three types: aluminum-cased cells, pouch cells (also known as polymer cells), and cylindrical cells. Mobile phone batteries typically use aluminum-cased cells, while Bluetooth and other digital products often use pouch cells. Laptop batteries use a series-parallel combination of cylindrical cells.

[0003] Currently, in the production process of pouch cells, a baking process is required. Many existing pouch cell baking methods use a screw-guided extrusion method. This method has disadvantages such as large mechanical area, small number of cells to be baked, complex structure, and high processing and assembly difficulty. At the same time, when placing pouch cells, it is easy to cause the pouch cell tabs to come into contact, resulting in a short circuit. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a precision positioning fixture for preventing short circuits in battery cells. This positioning fixture can clamp and position multiple sets of soft-pack battery cells at the same time, and can effectively avoid short circuits caused by contact between the battery cell tabs.

[0005] To solve the above problems, the following technical solutions are provided:

[0006] The design includes a precision positioning fixture for preventing short circuits in battery cells, comprising a base, a placement plate on top of the base, a slide rail assembly between the placement plate and the base, a placement component for separating multiple battery cells on top of the placement plate, a clamping component for preventing the battery cells from tipping over on the placement plate, and a limiting component for restricting the displacement of the placement plate between the base and the placement plate.

[0007] Furthermore, the placement component includes two symmetrically arranged adjustment grooves on the upper surface of the placement plate. The inner walls of the adjustment grooves are slidably connected with positioning stops and support seats. The two support seats are located between the two positioning stops. Each positioning stop has multiple grooves I on its opposite side, and each support seat has a groove II corresponding to the grooves I.

[0008] Furthermore, the clamping member includes two clamping adjustment seats that can move on the placement plate. The upper surface of the clamping adjustment seats is provided with multiple stops at equal intervals. Each stop includes a first part and a second part. The first part is located at the bottom end of the second part. The first part is a columnar structure, and the second part is an arc-shaped structure. The second part on the same clamping adjustment seat has the same bending direction, while the second part on the two adjustment seats has different bending directions.

[0009] Furthermore, the limiting member includes a mounting plate disposed on the base, a male connector disposed on the mounting plate, a slot corresponding to the mounting plate being opened on the side of the placement plate, a female connector corresponding to the male connector being fixedly disposed on the inner wall of the slot, and a buffer post being disposed on the mounting plate.

[0010] Furthermore, a positioning sensor is fixedly installed at the bottom of the inner wall of the base, and a positioning piece corresponding to the positioning sensor is fixedly installed on the side wall of the slot. When the slide rail assembly is in a fully retracted state, the positioning piece is located inside the positioning sensor.

[0011] Furthermore, the side of the placement plate is provided with a handle to facilitate the pulling of the placement plate by the staff.

[0012] Furthermore, a U-shaped mounting housing is fixedly provided on one side of the base, and a connecting plate is fixedly provided on the upper surface of the placement plate near the U-shaped mounting housing. A drag chain is provided between the connecting plate and the U-shaped mounting housing.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. By using a slide rail assembly, workers can pull out the placement plate by pulling the handle, which facilitates the placement of the soft-pack battery cells. The placement component can separate two adjacent battery cells, which can effectively prevent the battery cell tabs from contacting each other and causing short circuits. The clamping component can clamp and position the battery cells, which facilitates subsequent processes for the soft-pack battery cells.

[0015] 2. By setting a baffle including a first part and a second part, wherein the first part is a columnar structure and the second part is an arc-shaped structure, and the second part on the same clamping adjustment seat has the same bending direction, it is convenient and quick for the staff to place the soft-pack battery cells.

[0016] 3. By using male and female connectors, the slippage of the placement board during the processing of soft-pack battery cells can be effectively prevented, thus effectively improving stability. Attached Figure Description

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0025] like Figure 1 - Figure 5 As shown, the precision positioning fixture for preventing short circuits of battery cells provided in this embodiment includes a base 1, a placement plate 2 disposed above the base 1, a slide rail assembly 3 disposed between the placement plate 2 and the base 1, a placement component for separating multiple battery cells disposed above the placement plate 2, a clamping component for preventing the battery cells from tipping over disposed on the placement plate 2, and a limiting component for restricting the displacement of the placement plate 2 disposed between the base 1 and the placement plate 2. In this embodiment, by using the slide rail assembly 3, the operator can pull out the placement plate 2 by pulling the handle 17, which facilitates the handling of the soft packaging. The battery cells are placed by means of a placement component that separates adjacent cells, effectively preventing short circuits caused by contact between cell tabs. A clamping component is used to clamp and position the cells, facilitating subsequent processes for the soft-pack cells. When placing the cells, first pull handle 17 to remove the placement plate 2, then place multiple cells into the placement component, and clamp and position the cells under the action of the clamping component. Then push the placement plate 2 in the opposite direction, and fix the placement plate 2 under the action of the limiting component.

[0026] The placement component includes two symmetrically arranged adjustment grooves 4 on the upper surface of the placement plate 2. The inner walls of the adjustment grooves 4 are slidably connected with positioning stops 5 and support seats 7. The two support seats 7 are located between the two positioning stops 5. The opposite side of each positioning stop 5 is provided with a plurality of grooves 6. Each support seat 7 is provided with a groove 8 corresponding to the grooves 6. In this embodiment, in order to place cells of different sizes and specifications, the positioning stops 5 and support seats 7 are moved in the adjustment grooves 4 until the distance between the two positioning stops 5 and the two support seats 7 is adjusted to a suitable position. The positioning stops 5 and support seats 7 are then fixed to the placement plate 2 with bolts.

[0027] The clamping component includes two clamping adjustment seats 9 that can move on the placement plate 2. Multiple stop bars 10 are evenly spaced on the upper surface of each clamping adjustment seat 9. Each stop bar 10 includes a first part and a second part. The first part is located at the bottom of the second part. The first part has a columnar structure, and the second part has an arc-shaped structure. The second parts on the same clamping adjustment seat 9 have the same bending direction, while the second parts on two adjustment seats 9 have different bending directions. In this embodiment, multiple position detection sensors 21 corresponding to the grooves 8 are fixedly installed on the upper surface of the placement plate 2. These sensors 21 are used to detect the distance between the two positioning stop bars 5. The distance between the two positioning stops 5 is easily adjusted by the staff. The stop bar 10 includes a first part and a second part. The first part is a columnar structure and the second part is an arc-shaped structure. The second part on the clamping adjustment seat 9 has the same bending direction as the first part. This makes it convenient and quick for the staff to place the soft-pack battery cell. The clamping adjustment seat 9 is provided with a through groove that runs vertically through the middle. A bolt is installed in the through groove. The clamping adjustment seat 9 can move under the restriction of the bolt. The bottom end of the bolt is threaded to the placement plate 2. After the clamping of the battery cell is completed, the clamping adjustment seat 9 is fixed by rotating the bolt.

[0028] The limiting component includes a mounting plate 11 disposed on the base 1, a male connector 12 disposed on the mounting plate 11, a slot corresponding to the mounting plate 11 opened on the side of the placement plate 2, a female connector 13 corresponding to the male connector 12 fixedly disposed on the inner wall of the slot, and a buffer post 14 disposed on the mounting plate 11. In this embodiment, the buffer post 14 can effectively buffer the placement plate 2 to avoid damage to the battery cell due to collision.

[0029] A positioning sensor 15 is fixedly installed at the bottom of the inner wall of the base 1, and a positioning piece 16 corresponding to the positioning sensor 15 is fixedly installed on the side wall of the slot. When the slide rail assembly 3 is in a fully retracted state, the positioning piece 16 is located inside the positioning sensor 15. In this embodiment, when the placement plate 2 slides, the positioning piece 16 separates from the positioning sensor 15, and the positioning sensor 15 sends a signal to warn the staff.

[0030] The side of the placement plate 2 is provided with a handle 17 to facilitate the operation of the staff. The surface of the handle 17 is provided with anti-slip texture to prevent slippage during the operation of the placement plate 2.

[0031] A U-shaped mounting housing 18 is fixedly installed on one side of the base 1. A connecting plate 20 is fixedly installed on the upper surface of the placement plate 2 near the U-shaped mounting housing 18. A drag chain 19 is provided between the connecting plate 20 and the U-shaped mounting housing 18. By setting the drag chain 19, the wires can be effectively organized, avoiding the phenomenon of wires affecting the process of processing the battery cell.

[0032] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
