Description

Technical Field

[0001] This invention relates to the field of lithium battery packaging crimping, and more specifically to crimping equipment for crimping button-type lithium battery packages. Background Technology

[0002] The encapsulation and crimping of lithium batteries is the most important process before the electrode sheet is formed. The quality of the crimping directly affects the quality of the lithium battery and the production cost.

[0003] In existing technologies, the unevenness of the electrode plates at both ends of lithium batteries is mainly caused by uneven deformation during electrode rolling, small and uneven front and rear tension, or errors in electrode coating thickness. Without corresponding positioning and adjustment when entering the crimping assembly, it is not conducive to the crimping and forming of the electrode plates, which affects the quality and cost of lithium battery crimping. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned defects and provide a crimping device for crimping button-type lithium battery packaging, thereby solving the problems mentioned in the background art.

[0005] The objective of this invention is achieved through the following means:

[0006] A crimping device for crimping button-type lithium battery packaging includes an operating table, a positioning component, a connecting component, and a crimping component. The connecting component includes a left-right adjusting seat, a front-back adjusting seat, a connecting plate, a support plate, an upper cylinder fixing plate, a lower cylinder fixing plate, and a guide rail. The crimping component includes a lower pressing cylinder, an upper lifting cylinder, an upper adjusting seat, a lower adjusting seat, an upper crimping block, and a lower crimping block. The upper crimping block and the lower crimping block are respectively installed on one side of the upper adjusting seat and the lower adjusting seat. A positioning shaft is provided in the middle of the lower crimping block, and a positioning sleeve that matches the positioning shaft is provided in the middle of the upper crimping block. A crimping piece is provided between the positioning shaft and the positioning sleeve.

[0007] Furthermore, as described above, the positioning assembly includes a control box, a rotating platform, a mounting plate, a fixing clamp, a sensing plate, a sensing bracket, and a sensor. The fixing clamp is mounted on the top of the mounting plate, with one end of the fixing clamp serving as a clamping part, and a support block connected to the bottom of the clamping part.

[0008] Furthermore, as described above, the guide rail is connected to an upper slider and a lower slider. The upper slider and the lower slider are respectively equipped with an upper slide seat and a lower slide seat. An upper adjusting seat is installed on one side of the upper slide seat, and a lower adjusting seat is installed on one side of the lower slide seat. The upper adjusting seat and the lower adjusting seat can be moved by the slider. The high precision of the slider can make the repeatability of the upper adjusting seat and the lower adjusting seat more stable and uniform.

[0009] Furthermore, as described above, the downward pressing cylinder and the upward pressing cylinder are respectively installed on one side of the upper cylinder fixing plate and the lower cylinder fixing plate.

[0010] Furthermore, as described above, the middle part of the positioning shaft is hollow, the top of the positioning shaft is toothed and tilted, which is beneficial for the encapsulation and wrinkling of the lithium battery.

[0011] Furthermore, as described above, both the positioning shaft and the positioning sleeve have openings on one side for pairing the crimping pieces. The crimping pieces press the lithium battery package surface to crimp, reducing package displacement during crimping and ensuring that the crimped position is stable and uniform.

[0012] Furthermore, as described above, the push rods of the downward pressing cylinder and the upward pressing cylinder point to the upper adjusting seat and the lower adjusting seat, respectively, and both the upper adjusting seat and the lower adjusting seat are provided with urethane blocks on the side near the push rod.

[0013] Furthermore, as described above, baffles are provided on both sides of the upper and lower creasing blocks to prevent the packaging from deviating during creasing.

[0014] The beneficial effects of this invention are as follows: When the equipment is working, the positioning component feeds the lithium battery that needs to be wrinkled after the previous process is completed into the wrinkling component. The wrinkling component starts to perform the wrinkling work. The positioning shaft in the middle of the lower wrinkling block can quickly position the lithium battery, making the repeated positioning of the lithium battery more accurate and reducing the positional deviation of the wrinkling. The push rod of the lower pressing cylinder drives the upper adjusting seat and the upper wrinkling block to move downward, and the push rod of the upper lifting cylinder drives the lower adjusting seat and the lower wrinkling block to move upward. The wrinkling piece is located between the positioning shaft and the positioning sleeve. One end of the wrinkling piece is used to press the electrode of the lithium battery to prevent the electrode from deviating during wrinkling. The upper and lower wrinkling blocks are set in parallel, so that the wrinkling force of the lithium battery electrode is uniform and balanced. By adjusting the upper and lower adjusting seats, the relative position of the upper and lower wrinkling blocks can be adjusted, which helps to reduce the unevenness of the wrinkling deformation of the lithium battery electrode, improve the wrinkling efficiency of the lithium battery and reduce the wrinkling cost.

Detailed Implementation

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0020] In this embodiment, refer to Figures 1-3 The specific implementation of the crimping equipment for crimping button-type lithium battery packaging includes an operating table 1, a positioning component, a connecting component, and a crimping component. The connecting component includes a left and right adjusting seat 2, a front and rear adjusting seat 3, a connecting plate 4, a support plate 5, an upper cylinder fixing plate 6, a lower cylinder fixing plate 7, and a guide rail 8. The crimping component includes a lower pressing cylinder 9, an upper lifting cylinder 10, an upper adjusting seat 11, a lower adjusting seat 12, an upper crimping block 13, and a lower crimping block 14. The upper crimping block 13 and the lower crimping block 14 are respectively installed on one side of the upper adjusting seat 11 and the lower adjusting seat 12. A positioning shaft 15 is provided in the middle of the lower crimping block 14, and a positioning sleeve 16 that matches the positioning shaft 15 is provided in the middle of the upper crimping block 13. A crimping piece 17 is provided between the positioning shaft 15 and the positioning sleeve 16.

[0021] The positioning assembly includes a control box 18, a rotating platform 19, a mounting plate 20, a fixing clamp 21, a sensing plate 22, a sensing bracket 23, and a sensor 24. The fixing clamp 21 is installed on the top of the mounting plate 20. One end of the fixing clamp 21 is a clamping part, and a support block 25 is connected to the bottom of the clamping part. The guide rail 8 is connected to an upper slider 26 and a lower slider 27. The upper slider 26 and the lower slider 27 are respectively equipped with an upper slide seat 28 and a lower slide seat 29. An upper adjusting seat 11 is installed on one side of the upper slide seat 28, and a lower adjusting seat 12 is installed on one side of the lower slide seat 29. The upper adjusting seat 11 and the lower adjusting seat 12 can be moved by the slider. The high precision of the slider makes the repeatability of the upper adjusting seat 11 and the lower adjusting seat 12 more stable and uniform. The lower pressing cylinder 9 and the upper lifting cylinder 10 are respectively installed on one side of the upper cylinder fixing plate 6 and the lower cylinder fixing plate 7.

[0022] The center of the positioning shaft 15 is hollow, and the top of the positioning shaft 15 is toothed and tilted, which is beneficial for the crimping of the lithium battery. Both the positioning shaft 15 and the positioning sleeve 16 have an opening 30 on one side for matching the crimping piece 17. The crimping piece 17 presses the surface of the lithium battery package to crimp, reducing the package displacement during crimping and making the crimping position stable and uniform. The push rods of the lower pressing cylinder 9 and the upper pushing cylinder 10 point to the upper adjusting seat 11 and the lower adjusting seat 12, respectively. Both the upper adjusting seat 11 and the lower adjusting seat 12 have urethane blocks 31 on the side near the push rod. Both sides of the upper crimping block 13 and the lower crimping block 14 have baffles 32 to prevent the package from deviating during crimping.

[0023] When the equipment is working, the positioning component feeds the lithium battery that has been completed in the previous process and needs to be crimped into the crimping component. The crimping component starts to crimp. The positioning shaft 15 in the middle of the lower crimping block 14 can quickly position the lithium battery, making the repositioning of the lithium battery more accurate and reducing the positional deviation of the crimping. The push rod of the lower pressing cylinder 9 drives the upper adjusting seat 11 and the upper crimping block 13 to move downward, and the push rod of the upper lifting cylinder 10 drives the lower adjusting seat 12 and the lower crimping block 14 to move upward. The crimping sheet 17 Located between the positioning shaft 15 and the positioning sleeve 16, one end of the creasing piece 17 is used to press the electrode of the lithium battery to prevent the electrode from deviating during creasing. The upper creasing block 13 and the lower creasing block 14 are arranged in parallel to ensure that the creasing force of the lithium battery electrode is uniform and balanced. The relative position of the upper creasing block 13 and the lower creasing block 14 can be adjusted by adjusting the upper adjusting seat 11 and the lower adjusting seat 12, which helps to reduce the unevenness of the creasing deformation of the lithium battery electrode, improve the creasing efficiency of the lithium battery and reduce the creasing cost.
