Description

Technical Field

[0001] This utility model belongs to the field of battery cell manufacturing technology, specifically relating to an integrated extrusion and flipping mechanism. Background Technology

[0002] The battery cell is one of the core components of a battery, typically consisting of electrodes, a separator, and an electrolyte. Based on a chemical reaction, the battery cell stores and releases electrical energy. During battery cell production, to ensure structural integrity and sealing, the cells are usually squeezed and flipped to check for leakage.

[0003] In related technologies, battery cells are typically tested for leakage using a cell extrusion and flipping device. This device includes an extrusion mechanism and a flipping mechanism, which have independent extrusion and flipping stations. The extrusion mechanism can extrude the battery cell at the extrusion station. After the battery cell is extruded and compacted, it is transferred to the flipping station, where the flipping mechanism flips the battery cell to detect leakage.

[0004] However, the battery cell needs to be transferred multiple times during the leakage detection process, which is cumbersome. Furthermore, the number of battery cells that can be squeezed by the squeezing mechanism and flipped by the flipping mechanism at a time is relatively small, resulting in low detection efficiency of the battery cell squeezing and flipping device. Utility Model Content

[0005] To address the shortcomings of the prior art, this utility model provides an integrated extrusion and flipping mechanism. The extrusion drive drives the fixture to extrude the workpiece to be tested, and the rotation drive drives the rotating seat and fixture to rotate. The battery cell is extruded and flipped for leakage detection. The battery cell does not need to be transferred multiple times during the leakage detection process, making the operation convenient. The fixture can extrude and flip a large number of battery cells at a time, which helps to improve the efficiency of leakage detection.

[0006] The technical effects to be achieved by this utility model are realized through the following technical aspects:

[0007] In a first aspect, this utility model provides an integrated extrusion and flipping mechanism, comprising a rotating seat and a rotary drive connected to it for rotating the rotating seat. The rotating seat includes a guide member arranged along its length; a clamp comprising a plurality of clamping plates arranged side by side on the guide member and slidable along the extension direction of the guide member; a pressing area for extruding the workpiece to be tested is provided between the clamping plates; a connecting member with a deformation function is provided on one side of the clamp and connected to each of the clamping plates for linkage of the clamping plates; the connecting member can deform under force within a preset length; and an extrusion drive member is connected to the clamping plate at one end of the guide member for pushing the clamp to press the workpiece to be tested in the pressing area, or pulling the clamp to release the workpiece to be tested in the pressing area.

[0008] In some implementations, the connector is a chain, which is connected to the clamping plate. A movable element is provided between the chain and the rotating seat, and the chain and the rotating seat are rotatably connected to the movable element.

[0009] In some implementations, a slide is provided on one side of the clamping plate, and the slide is connected to the connecting member; the guide member is a guide shaft, and the slide passes through the guide shaft and is slidably connected to the guide shaft.

[0010] In some implementations, a pulley is rotatably mounted on the slide block, and the pulley rolls on the rotating seat when the slide block slides along the guide shaft.

[0011] In some implementations, the clamp further includes a fixing plate, which is disposed on the rotating seat and located at the end of the sliding direction of the plurality of clamps, and a buffer is provided between the fixing plate and the adjacent clamps.

[0012] In some implementations, a sensor for detecting the rotation angle of the rotating base is provided on one side of the rotating base.

[0013] In some implementations, a limiting member is provided on one side of the rotating seat for positioning the rotating seat after rotation.

[0014] In some implementations, the limiting member includes a limiting rod with a buffer on it, and the rotating seat abuts against the buffer after rotation to limit the rotation angle of the rotating seat.

[0015] In some implementations, the extrusion drive is an extrusion cylinder, the output end of which pushes the clamp to press or release the workpiece to be tested in the pressing area.

[0016] In some implementations, a positioning plate is provided on the side of the clamping plate near the pressing area. The positioning plate has a positioning groove for positioning the workpiece to be tested in the pressing area. When the clamp squeezes the workpiece to be tested, the workpiece to be tested is located in the limiting groove.

[0017] In summary, this utility model has at least the following advantages:

[0018] The integrated extrusion and flipping mechanism provided by this utility model allows for leakage detection. During leakage detection, the workpiece to be tested is fed into the clamping area. The extrusion drive pushes the clamping plate, which slides along the extension direction of the guide to clamp the workpiece within the clamping area. A rotation drive drives a rotating seat to rotate, which in turn rotates the clamp. The clamp extrudes and flips the workpiece, pausing after flipping to detect any leakage. Compared to traditional cell extrusion and flipping devices, this integrated extrusion and flipping mechanism achieves an integrated structure for both extrusion and flipping. This integrated mechanism reduces the space occupied and saves manufacturing costs. Furthermore, the workpiece does not require multiple transfers during leakage detection, improving detection efficiency. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.

[0031] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0032] Example 1:

[0033] Please see the appendix Figure 1 The integrated squeezing and flipping mechanism of this utility model can be used in cell leakage detection. The integrated mechanism helps to reduce the number of times the cell 5 is transferred during leakage detection and improves the single-machine detection efficiency.

[0034] The extrusion and flipping integrated mechanism of this utility model includes a rotating base 1, which is specifically horizontally arranged. The rotating base 1 is connected to a rotation drive 11, which drives the rotating base 1 to rotate. A guide 12 is provided on the rotating base 1.

[0035] The rotating seat 1 is provided with a clamp 2 for squeezing the battery cell 5. The clamp 2 includes several clamping plates 21, which are specifically vertically arranged long plates. Several clamping plates 21 are arranged side by side on the guide member 12 and can slide along the extension direction of the guide member 12. A pressing area 211 for squeezing the battery cell 5 is provided between two adjacent clamping plates 21. During leakage detection, the clamping plates 21 squeeze the battery cell 5 located in the pressing area 211.

[0036] A connector 33 with deformation function is provided on one side of the clamp 2. The connector 33 is connected to each clamp 21 to link the clamp 21. The connector 33 can be deformed under force within a preset length. When the clamps 21 slide along the guide 12, the connector 33 deforms with the sliding of the clamps 21. The clamps 21 are linked together by the connector 33 when the battery cell 5 is squeezed or released.

[0037] A pressing drive 4 is provided on one side of the clamp 2. The pressing drive 4 is connected to the clamping plate 21 at one end of the guide 12. The pressing drive 4 pushes the corresponding clamping plate 21 to make the clamp 2 press the battery cell 5 in the pressing area 211, or pull the clamp 2 to release the battery cell 5 in the pressing area 211.

[0038] When performing leakage detection on battery cell 5, the battery cell 5 to be tested is loaded into the clamping area 211. The extrusion drive 4 drives the push clamp 2, which in turn extrudes the battery cell 5. The rotation drive 11 drives the rotating seat 1 to rotate, and the rotating seat 1 drives the clamp 2 to rotate synchronously. The clamp 2 flips the extruded battery cell 5 180° so that the injection port faces downwards. After flipping, the battery cell 5 pauses for a certain period of time to observe whether there is a leakage problem. Unqualified battery cells 5 will leak from the injection port. After the leakage detection is completed, the rotation drive 11 drives the rotating seat 1 and the clamp 2 to rotate back to their original positions, and the unloading robot can unload the battery cell 5. Through the leakage monitoring device, it is possible to detect in a timely manner whether the battery cell 5 held by the clamp 2 leaks after extrusion and flipping. Compared with the traditional battery cell 5 extrusion and flipping device, the integrated mechanism can reduce the number of transfers of the battery cell 5 between the extrusion and flipping operations, and can perform the extrusion and flipping operations simultaneously after the clamp 2 clamps the battery cell 5, so as to effectively detect the leakage battery cell 5. The clamp 2 can simultaneously squeeze and flip multiple battery cells 5, which helps to improve production efficiency.

[0039] Example 2:

[0040] The difference between this embodiment and embodiment 1 is that this embodiment further optimizes the structure of the connector 3 and guide 12 of this utility model.

[0041] Please see Figure 2 In this embodiment, a slide 212 is provided on the clamping plate 21. As shown in some specific embodiments, the slide 212 is located on both sides of the sliding direction of the clamping plate 21. The slide 212 and the clamping plate 21 are detachably connected. Specifically, a connecting piece is provided between the slide 212 and the clamping plate 21. The connecting piece has an oblong hole. The length direction of the oblong hole is perpendicular to the sliding direction of the clamping plate 21. The connecting piece can be connected to the slide 212 and the clamping plate 21 at the oblong hole by bolts. The distance between the slide 212 and the clamping plate 21 can be adjusted by the connecting piece to ensure that the clamp 2 can slide along the guide member 12.

[0042] In a preferred embodiment, the guide member 12 is a guide shaft 121, and the slide 212 passes through and is slidably connected to the guide shaft 121. Specifically, several guide shafts 121 can be provided on one side of the clamp 2, arranged side by side, and each guide shaft 121 is slidably connected to the slide 212. This guides the sliding process of the clamping plate 21 and improves the stability of the clamping plate 21 when pressing the battery cell 5. Specifically, a bushing is provided at the sliding connection between the slide 212 and the guide shaft 121. The bushing is connected to the slide 212 and sleeved on the guide shaft 121. The bushing improves the smoothness of the sliding of the slide 212. In other specific embodiments, the guide member 12 can also be a guide rail, and the slide 212 is slidably connected to the guide rail to limit and guide the movement of the slide 212.

[0043] In a preferred embodiment, a mounting base is provided on the slide 212, and the mounting base is detachably connected to the slide 212. Specifically, the mounting base and the slide 212 can be assembled by bolts. A pulley 213 is rotatably mounted on the mounting base. When the clamping plate 21 slides along the extension direction of the guide member 12, the pulley 213 rolls on the rotating seat 1, which helps to improve the smoothness of the slide 212 driving the clamping plate 21 to slide, so that the clamp 2 can smoothly compress the battery cell 5 under the driving action of the compression drive member 4. Specifically, several mounting bases and pulleys 213 are provided, and the operator can adjust the specific number of mounting bases and pulleys 213 according to the actual testing requirements.

[0044] In a preferred embodiment, the connector 3 is a chain 31, which is connected to the slide 212 corresponding to each clamping plate 21. When the extrusion drive 4 pushes the clamp 2 to extrude the battery cell 5, the clamping plates 21 slide along the guide shaft 121 via the slide 212. The chain 31 is deformed and bent under the action of the slide 212, reducing the space of the pressing area 211 between adjacent clamping plates 21, thereby extruding the battery cell 5 within the pressing area 211. When the clamp 2 returns to its original position to release the battery cell 5, the clamping plates 21 slide in the opposite direction along the guide shaft 121 via the slide 212. The chain 31 returns to its straight state under the action of the slide 212, increasing the space of the pressing area 211 between two adjacent clamping plates 21, and the clamp 2 releases the battery cell 5. The chain 31 has a certain deformation function and can link several slides 212, which is beneficial for the clamp 2 to quickly extrude or release the battery cell 5. A movable member 32 is provided between one end of the chain 31 and the rotating seat 1. The movable member 32 is preferably, but not limited to, a movable plate. The chain 31 and the rotating seat 1 are rotatably connected to the movable member 32, providing clearance space for the deformation process of the chain 31.

[0045] In some other specific embodiments, the connector 3 may also be a belt with a specific deformation function to link several slides 212.

[0046] In a preferred embodiment, the clamp 2 further includes a fixing plate 22, which is located on the rotating seat 1 and at the end of the sliding direction of the plurality of clamping plates 21. A pressing area 211 can also be formed between the fixing plate 22 and the adjacent clamping plates 21. When the extrusion drive 4 drives the clamp 2 to extrude the battery cell 5, the plurality of clamping plates 21 move closer to the fixing plate 22 along the guide shaft 121 in sequence to gradually extrude the plurality of battery cells 5 to be tested held by the clamp 2. A buffer 221 is provided between the fixing plate 22 and the adjacent clamping plates 21. The buffer 221 is preferably, but not limited to, a buffer spring. The buffer spring can buffer the extrusion force between the clamping plates 21 and the fixing plate 22, reduce the impact of the collision between the clamping plates 21 and the fixing plate 22 when the extrusion drive 4 drives the plurality of clamping plates 21 closer to the fixing plate 22, so as to extend the service life of the extrusion and flipping integrated mechanism.

[0047] In a preferred embodiment, a positioning plate 23 is provided on the side of the clamping plate 21 near the pressing area 211. The positioning plate 23 has a positioning groove 231 for positioning the battery cell 5. When the clamp 2 presses the battery cell 5, the battery cell 5 is located in the positioning groove. As shown in some specific embodiments, the positioning groove 231 is adapted to the battery cell 5 so that the battery cell 5 can be in a suitable position when it is fed into the pressing area 211, which facilitates the clamping plate 21 to clamp the battery cell 5 and improves the convenience of operation.

[0048] When the extrusion drive 4 drives the clamp 2 to extrude the battery cell 5, the extrusion drive 4 drives the clamping plate 21 at one end of the guide 12 to move towards the fixed plate 22. The clamping plate 21 pushes the battery cell 5 in the pressing area 211 and the adjacent clamping plate 21 towards the fixed plate 22. Several clamping plates 21 repeat the above operation to clamp and extrude several battery cells 5 to be tested. The slide 212 slides along the guide shaft 121, and the chain 31 deforms under force. When the clamp 2 releases the battery cell 5, it pulls the clamping plate 21 at one end of the extrusion drive 4 to move away from the fixed plate 22. The clamping plate 21 drives the remaining clamping plates 21 to be pulled open in sequence through the connector 3. The clamp 2 releases the battery cell 5. The connector 3 has a simple structure and is easy to operate.

[0049] Example 3:

[0050] The difference between this embodiment and the above embodiments is that this embodiment further optimizes the structure of the rotating base 1 of the present invention.

[0051] Please see Figure 3-5 The extrusion drive 4 of this utility model preferably, but is not limited to, adopts an extrusion cylinder. The extrusion cylinder can be installed on the rotating seat 1. A push seat is provided on the clamping plate 21 adjacent to the extrusion cylinder. The extrusion cylinder pushes the push seat on the clamping plate 21 by changing the stroke of the piston rod, thereby driving the clamp 2 to clamp and extrude the battery cell 5.

[0052] In a preferred embodiment, the rotary drive 11 preferably, but not limited to, adopts a flip motor. The output end of the flip motor is connected to the rotating seat 1 to drive the rotating seat 1 to rotate. In some specific embodiments shown, the output end of the flip motor is connected to a reducer 111, which is connected to the rotating seat 1, which is beneficial to achieve accurate positioning of the rotating seat 1 after flipping.

[0053] In a preferred embodiment, a support base 15 is provided on one side of the rotating seat 1, and the rotating seat 1 is rotatably mounted on the support base 15. A sensor 13 for detecting the rotation angle of the rotating seat 1 is provided on the support base 15, and the sensor 13 is located on one side of the rotating seat 1. A limiting member 14 for positioning the rotating seat 1 after rotation is provided on the support base 15. As shown in some specific embodiments, the limiting member 14 is located at the bottom of the rotating seat 1. The limiting member 14 includes a limiting rod 141, which is specifically vertically arranged. A buffer 142 is provided at one end of the limiting rod 141 near the rotating seat 1. The buffer 142 is preferably, but not limited to, a hydraulic buffer. When the rotation drive 11 drives the rotating seat 1 to rotate 180° to flip the battery cell 5 into place, the rotating seat 1 presses against the hydraulic buffer 142. The hydraulic buffer 142 buffers the rotation positioning of the rotating seat 1, and the rotating seat 1 stops rotating. The sensor 13 and the limiting member 14 cooperate to make the rotating seat 1 quickly flip and position itself.
