Description

Technical Field

[0001] This invention relates to the field of micro ring battery cell processing technology, specifically to a hot pressing feeding device compatible with multi-specification micro ring battery cells. Background Technology

[0002] In the production process of miniature ring-shaped battery cells, hot-press testing is a key step to ensure the consistency and reliability of cell performance.

[0003] Traditional feeding devices are mostly one-piece structures designed according to the curvature of the battery cell. Although they can meet the positioning requirements of a single specification battery cell, the pressing amount of such devices is uniform and cannot be effectively adjusted according to the different thicknesses of the battery cells. In order to prevent the tabs of the micro ring battery cells from deforming and interlocking during pressing, limit steps are set on the feeding device. Although this can prevent interlocking, it also affects the picking and placing of battery cells because it is not adjustable.

[0004] As can be seen from the above, the traditional design still has the problems of fixed pressing amount, inability to adjust according to the difference in cell thickness, and difficulty in changing the design. Therefore, a hot pressing feeding device compatible with multi-specification micro ring cells is proposed to solve the above-mentioned problems. Summary of the Invention

[0005] The purpose of this invention is to provide a hot-pressing feeding device compatible with multi-specification micro ring battery cells, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a hot pressing and feeding device for multi-specification micro ring battery cells, including a press support assembly, a shelf assembly mounted on the top of the press support assembly, a feeding fixture assembly mounted on the top of the shelf assembly, a test probe assembly mounted on the top of the shelf assembly, and the outer side of the test probe assembly being disposed with the outer side of the feeding fixture assembly; The feeding fixture assembly includes a miniature ring finger battery cell, a first fixture core plate is mounted on the outside of the miniature ring finger battery cell, a second fixture core plate is mounted on the outside of the miniature ring finger battery cell, a fixture guard plate is mounted on the outside of the second fixture core plate, a fixture base is mounted on the bottom of the fixture guard plate, and the bottom of the fixture base is fixedly mounted to the top of the shelf assembly. The test probe assembly includes a probe plate, the bottom of which is disposed on the top of the layer plate assembly. A probe holder assembly is fixedly connected to the bottom of the probe plate, and the bottom of the probe holder assembly is fixedly installed on the top of the layer plate assembly.

[0007] Preferably, an eccentric shaft is provided on the top of the clamp guard plate, and a shaft mounting seat is installed on the outer surface of the eccentric shaft. The bottom of the shaft mounting seat is fixedly installed to the top of the clamp guard plate.

[0008] Preferably, a first cover plate is provided on the outer side of the eccentric shaft, and the bottom of the first cover plate is fixedly connected to the top of the shaft mounting seat.

[0009] Preferably, an adjusting shaft is installed on the top of the clamp base, a partition plate is provided on the outer side of the clamp guard plate, and the bottom of the partition plate is installed inside the clamp base.

[0010] Preferably, the outer surface of the adjusting shaft is mounted on the outer side of the partition plate, and the outer side of the partition plate is adapted to the miniature ring finger cell.

[0011] Preferably, a second cover plate is provided on the outer side of the partition plate, and the outer side of the second cover plate is fixedly installed with the outer side of the clamp base.

[0012] Preferably, the shelf assembly includes a shelf body, and a limiting slide rail is fixedly connected to the top of the shelf body, and two limiting slide rails are provided.

[0013] Preferably, the top of the shelf body is fixedly connected with a positioning buckle, and two positioning buckles are provided, with the tops of both positioning buckles installed on the outside of the fixture base.

[0014] Preferably, there are two test probe assemblies, with the bottom of each probe base assembly mounted on the top of the limiting slide rail, and each probe plate being adapted to the same miniature ring finger cell.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are: First, this invention uses a micro-ring finger battery cell for loading and testing. The equipment is manually started, and the upper part of the shelf assembly automatically moves closer together. When it reaches the correct position, the test probe assembly moves inward, and the micro-ring finger battery cell is tested through the probe plate on top of the probe holder. If the thickness of the micro-ring finger battery cell to be tested exceeds the predetermined range, the first clamping core plate in the loading fixture assembly is removed and replaced with the second clamping core plate, thus achieving thickness compatibility. The invention also addresses situations where the thickness of the micro-ring finger battery cells to be tested varies within the same batch. Because the shaft is eccentric, when it is rotated, it pushes the connected second clamping core plate to produce a slight displacement. Therefore, when the eccentric shaft is rotated, the second clamping core plate deviates from the center of the battery cell in the micro-ring finger battery cell, achieving thickness adjustment. The design of the movable clamping core plate is more flexible than the transmission process, allowing for greater compatibility and adjustments for cells with inconsistent thicknesses, ensuring the quality of the battery cells. To improve the quality and increase the product qualification rate of the equipment, a first cover plate covers the shaft mounting base and the eccentric shaft and is fixed to the base to prevent dust and debris from falling into the adjustment gap of the eccentric shaft, jamming the rotation track of the eccentric shaft, affecting the adjustment accuracy and lifespan. The separation is operated by the adjustment shaft, which is a push-button type and is installed on the top of the fixture base and connected to the separation plate. The operator operates by pressing or pulling the adjustment shaft. The separation plate is set on the outside of the fixture guard plate and installed at the bottom inside the fixture base, and is linked with the adjustment shaft. When the adjustment shaft is pressed, its position will change. The separation plate is inserted between the battery cell tabs to physically separate the positive and negative tabs, preventing the tabs from contacting each other and causing a short circuit. It also has the function of tidying up the tabs. It is usually used in the working state, that is, when the probe is pressed. The second cover plate covers and protects the linkage mechanism between the internal adjustment shaft and the separation plate, and provides lateral guidance and limit for the movement of the separation plate to ensure its movement trajectory is accurate.

[0016] Secondly, this invention uses the shelf body as the basic support for other components and installs a limiting slide rail. The top clamp base is fixedly installed by the positioning buckle on the top of the shelf body. When the clamp core plate needs to be replaced and the loading clamp assembly is disassembled and reassembled, the clamp base can be simply aligned with the positioning buckle for installation. This ensures that the center of the loading clamp assembly and the center of the test probe assembly are always consistent without secondary adjustment, which greatly improves the efficiency of changeover and the accuracy of positioning. The two test probe assemblies are pressed together from both sides of the cell at the same time, and the electrical performance of the positive and negative electrodes is tested simultaneously, which improves the testing efficiency and reliability. The limiting slide rail provides precise linear motion guidance for the test probe assembly. When the shelf assembly moves or the probe itself is pressed together, it ensures that the probe assembly always moves along the predetermined straight path, ensuring that the probe can be accurately aligned with the center of the cell tab.

[0019] 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 skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] This invention provides the following technical solutions: Example Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 A hot pressing feeding device for multi-specification micro ring battery cells includes a press support assembly 4, a shelf assembly 2 is mounted on the top of the press support assembly 4, a feeding fixture assembly 1 is mounted on the top of the shelf assembly 2, a test probe assembly 3 is mounted on the top of the shelf assembly 2, and the outer side of the test probe assembly 3 is disposed with the outer side of the feeding fixture assembly 1. The loading fixture assembly 1 includes a miniature ring finger battery cell 101. A first fixture core plate 102 is installed on the outside of the miniature ring finger battery cell 101. A second fixture core plate 103 is installed on the outside of the miniature ring finger battery cell 101. A fixture guard plate 104 is installed on the outside of the second fixture core plate 103. A fixture base 109 is installed at the bottom of the fixture guard plate 104. The bottom of the fixture base 109 is fixedly installed to the top of the shelf assembly 2. The test probe assembly 3 includes a probe plate 301, the bottom of which is disposed on the top of the layer plate assembly 2. A probe seat assembly 302 is fixedly connected to the bottom of the probe plate 301, and the bottom of the probe seat assembly 302 is fixedly installed on the top of the layer plate assembly 2.

[0021] The micro ring finger cell 101 is placed for loading and testing. The equipment is started manually, and the upper part of the shelf assembly 2 automatically moves closer. When it moves into place, the test probe assembly 3 moves inward and tests the micro ring finger cell 101 through the probe plate 301 on the top of the probe holder 302. When the thickness of the micro ring finger cell 101 to be tested exceeds the predetermined range, the first clamp core plate 102 in the loading fixture assembly 1 is removed and the second clamp core plate 103 is replaced to achieve thickness compatibility.

[0022] An eccentric shaft 105 is provided on the top of the clamp guard plate 104, and a shaft mounting seat 106 is installed on the outer surface of the eccentric shaft 105. The bottom of the shaft mounting seat 106 is fixedly installed to the top of the clamp guard plate 104.

[0023] The eccentric shaft 105 is turned to address situations where the thickness of the micro ring-shaped battery cells to be tested varies within the same batch. Since the shaft is eccentric, when it is turned, it will push the second clamping core plate 103 connected to it to produce a slight displacement. Therefore, when the eccentric shaft 105 is turned, the second clamping core plate 103 is deviated from the center of the battery cell in the micro ring-shaped battery cell 101, thereby achieving thickness adjustment. The design of the movable clamping core plate is more flexible than the transmission process, and can achieve more compatibility. It can also make certain adjustments for battery cells with inconsistent thickness, ensuring the quality of the battery cells and improving the product qualification rate of the equipment.

[0024] A first cover plate 107 is provided on the outer side of the eccentric shaft 105, and the bottom of the first cover plate 107 is fixedly connected to the top of the shaft mounting seat 106.

[0025] The first cover plate 107 covers the shaft mounting base 106 and the eccentric shaft 105 and is fixed to the base 106 to prevent dust and debris from falling into the adjustment gap of the eccentric shaft 105, jamming the rotation track of the eccentric shaft 105, and affecting the adjustment accuracy and lifespan.

[0026] An adjusting shaft 108 is installed on the top of the clamp base 109, and a partition plate 110 is provided on the outer side of the clamp guard plate 104. The bottom of the partition plate 110 is installed inside the clamp base 109.

[0027] The separation is operated by adjusting shaft 108, which is a push-button type. It is installed on the top of the fixture base 109 and connected to the separation plate 110. The operator operates by pressing or pulling up the adjusting shaft 108. The separation plate is located on the outside of the fixture guard plate 104, and its bottom is installed inside the fixture base 109. It is linked with the adjusting shaft 108. When the adjusting shaft 108 is pressed, its position will change.

[0028] The outer surface of the adjusting shaft 108 is mounted on the outer side of the partition plate 110, and the outer side of the partition plate 110 is adapted to the miniature ring finger cell 101.

[0029] The separator 110 is inserted between the battery cell tabs to physically separate the positive and negative tabs, preventing the tabs from contacting each other and causing a short circuit. It also serves to organize the tabs. It is usually used in the working state, that is, when the probes are pressed together.

[0030] A second cover plate 111 is provided on the outer side of the partition plate 110, and the outer side of the second cover plate 111 is fixedly installed on the outer side of the clamp base 109.

[0031] The second cover plate 111 covers and protects the linkage mechanism between the internal adjusting shaft 108 and the partition plate 110, and provides lateral guidance and limit for the movement of the partition plate 110, ensuring its movement trajectory is accurate.

[0032] The shelf assembly 2 includes a shelf body 201, and a limiting slide rail 202 is fixedly connected to the top of the shelf body 201. There are two limiting slide rails 202.

[0033] The shelf body 201 serves as the basic support for other components, and a limit slide rail 202 is installed.

[0034] The top of the shelf body 201 is fixedly connected with a positioning buckle 203. There are two positioning buckles 203, and the tops of the two positioning buckles 203 are installed on the outside of the clamp base 109.

[0035] The fixture base 109 at the top is fixedly installed by the positioning buckle 203 at the top of the shelf body 201. When the fixture core plate needs to be replaced and the loading fixture assembly 1 is disassembled and reassembled, the fixture base 109 can be simply aligned with the positioning buckle 203 for installation. This ensures that the center of the loading fixture assembly 1 and the center of the test probe assembly 3 are always consistent, without the need for secondary adjustment, which greatly improves the changeover efficiency and positioning accuracy.

[0036] There are two test probe assemblies 3. The bottom of each probe base assembly 302 is mounted on the top of the limiting slide rail 202. The two probe plates 301 are both adapted to the same miniature ring finger cell 101.

[0037] Two test probe assemblies 3 are used to press the battery cell from both sides simultaneously, and the electrical performance of the positive and negative electrodes is tested at the same time, which improves the testing efficiency and reliability. The limit slide rail 202 provides precise linear motion guidance for the test probe assembly 3. When the shelf assembly 2 moves or the probe presses itself, it ensures that the probe assembly 3 always moves along the predetermined straight path, ensuring that the probe can be accurately aligned with the center of the battery cell tab.

[0038] In use, the micro ring-finger battery cell 101 is placed for loading and testing. The equipment is manually started, and the upper part of the shelf assembly 2 automatically moves closer together. When it reaches the correct position, the test probe assembly 3 moves inward, and the micro ring-finger battery cell 101 is tested through the probe plate 301 on top of the probe holder 302. If the thickness of the micro ring-finger battery cell 101 to be tested exceeds the predetermined range, the first clamp core plate 102 in the loading fixture assembly 1 is removed, and the second clamp core plate 103 is replaced to achieve thickness compatibility. The eccentric shaft 105 can be turned to accommodate different thicknesses as needed. The tested miniature ring-shaped battery cells exhibited variations in thickness within the same batch. Because the shaft 105 is eccentric, its rotation causes a slight displacement in the connected second clamping core plate 103. Therefore, rotating the eccentric shaft 105 causes the second clamping core plate 103 to deviate towards the center of the miniature ring-shaped battery cell 101, thus adjusting the thickness. The design of the movable clamping core plate offers greater flexibility and compatibility compared to a transmission-based process. It also allows for adjustments to cells with inconsistent thicknesses, ensuring cell quality and improving equipment productivity. To improve the product qualification rate, a first cover plate 107 is placed over the shaft mounting base 106 and the eccentric shaft 105 and fixed to the base 106 to prevent dust and debris from falling into the adjustment gap of the eccentric shaft 105, jamming its rotation track, and affecting adjustment accuracy and lifespan. The separation is operated by an adjusting shaft 108, which is a push-button type, mounted on top of the clamp base 109 and connected to the separator plate 110. Operators operate by pressing or pulling the adjusting shaft 108. The separator plate is located on the outside of the clamp guard plate 104, at the bottom. Installed inside the fixture base 109 and linked with the adjusting shaft 108, the position of the adjusting shaft 108 changes when it is pressed. The separator plate 110 is inserted between the battery cell tabs to physically separate the positive and negative tabs, preventing them from contacting each other and causing a short circuit. It also serves to organize the tabs. It is usually used in the working state, that is, when the probe is pressed. The second cover plate 111 covers and protects the linkage mechanism between the adjusting shaft 108 and the separator plate 110, and provides lateral guidance and limit for the movement of the separator plate 110 to ensure its movement trajectory is accurate.The shelf body 201 serves as the basic support for other components and is equipped with a limiting slide rail 202. The top clamp base 109 is fixedly installed by the positioning buckle 203 on the top of the shelf body 201. When the clamp core plate needs to be replaced, the loading clamp assembly 1 is disassembled and reassembled. When reinstalling, the clamp base 109 is simply aligned with the positioning buckle 203. This ensures that the center of the loading clamp assembly 1 and the center of the test probe assembly 3 are always consistent without secondary adjustment, which greatly improves the efficiency of changeover and the accuracy of positioning. The two test probe assemblies 3 are pressed from both sides of the cell at the same time, and the electrical performance of the positive and negative electrodes is tested simultaneously, which improves the efficiency and reliability of testing. The limiting slide rail 202 provides precise linear motion guidance for the test probe assembly 3. When the shelf assembly 2 moves or the probe itself is pressed, it ensures that the probe assembly 3 always moves along the predetermined straight path, ensuring that the probe can be accurately aligned with the center of the cell tab.

[0039] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
