[0010] As a further embodiment of the invention, a telescopic probe is installed on the lower surface of the support block, and a detection probe is installed at the lower end of the telescopic probe.

[0011] As a further aspect of the invention, mounting bases are installed around the second motor. A limiting rod is provided on one side of the mounting base, and the mounting base is elastically hinged to the limiting rod via a torsion spring shaft. A friction block is fixedly connected to the side of the limiting rod near the transmission gear cylinder, and a permanent magnet is installed on the other side of the limiting rod. An electromagnet is installed on the outer wall of the second motor near the permanent magnet.

[0012] As a further embodiment of the invention, the clamping block assembly includes a positioning seat, a support plate fixedly connected to one side of the lower surface of the positioning seat, a clamping plate slidably connected to the other side of the lower surface of the positioning seat, a sensing component fixedly inserted through the middle of the support plate, and a plurality of second slide rods arranged around the sensing component, each second slide rod being evenly distributed in a ring array around the sensing component.

[0013] As a further embodiment of the invention, one end of the second slide rod is fixedly connected to the clamping plate, the other end of the second slide rod movably passes through the support plate, and a return spring is movably sleeved on the other end of the second slide rod. One end of the return spring is fixedly connected to the support plate, and the other end of the return spring is fixedly connected to a connecting plate. The connecting plate is fixedly connected to the second slide rod.

[0014] As a further aspect of the invention, the sensing component includes a mounting box, a through groove is provided in the middle of the inner side of the mounting box, a threaded sleeve is movably inserted in the through groove, one end of the threaded sleeve movably passes through one end of the mounting box, a pressure probe is installed at one end of the threaded sleeve, and a transmission screw is threadedly connected to the other end of the threaded sleeve.

[0015] As a further embodiment of the invention, a transmission worm gear is fixedly sleeved at the end of the transmission screw, and a worm gear cavity is opened on the inner side of the end of the mounting box and on the outer periphery of the transmission worm gear. A transmission worm is meshed on one side of the transmission worm gear, and the transmission worm is rotatably connected to the mounting box. One end of the transmission worm passes through the mounting box and is equipped with a knob. A third slide rod is installed on both sides of the pressure probe, and the third slide rod moves through the mounting box.

[0016] As a further aspect of the invention, a first transfer belt and a second transfer belt are arranged parallel to each other below the three-axis slide.

[0017] The beneficial effects of this invention are: (1) During operation, the second motor rotates the transmission gear cylinder, synchronously driving the two transmission racks, so that the two transmission sliders move towards the center of the transmission box in a centrally symmetrical manner until they clamp the two sides of the battery cell. The position of the detection probe in the horizontal direction is limited by the limiting spring. When the transmission slider moves to different positions to clamp battery cells of different sizes, the elastic force generated by the contraction of the limiting spring makes the detection slider always follow the movement of the transmission slider on the first slide rod. The position of the detection probe in the vertical direction is adapted by the telescopic probe rod to avoid damage to the electrodes by the detection probe, so as to ensure that the electrode positions of different battery cells are maintained. The device is designed to adapt to different battery cells and can be further adapted to cells with different electrode positions by replacing the limit springs with different elasticities. It determines the positive and negative poles of the battery cell based on the positive and negative potential detected by the detection probe, and can simultaneously obtain the battery cell's electrical energy parameters and detect the quality of the produced battery cells. Then, according to design requirements, the first motor rotates the clamping assembly to adjust the positive and negative pole positions of the battery cell, preparing for subsequent processing steps. When grouping battery cells, the clamping mechanism is moved by a three-axis slide table, thereby realizing the simultaneous and flexible adjustment of the battery cell's position and detection of the battery cell's electrical energy parameters, simplifying the overall process and improving work efficiency. (2) During operation, the two closing slides are extended to a horizontal position to close and position the grouped battery cells. When not closed, the closing slides are retracted by the lifting slides to avoid interfering with the movement of the battery cells. The clamping block assembly is closed synchronously by the two closing slides, so that adjacent battery cells in the group abut against each other and cooperate with the second transfer belt to adjust the position of the battery cells in adjacent groups. When the second motor stops rotating the transmission gear cylinder, the electromagnet starts and pushes the permanent magnet block, so that the friction block rubs against the transmission gear cylinder, so that the transmission gear cylinder remains stationary and cooperates with the second motor to lift the clamping block assembly. The device accurately positions the components and generates precise clamping force, avoiding damage to the second motor and maintaining accurate clamping force. This allows for quick clamping of the battery cell while ensuring controllable and consistent clamping force for each clamping, preventing damage to the battery cell and reducing clamping time. The clamping block assembly detects and samples the clamping force in a timely manner during clamping and closing. When the clamping assembly clamps the battery cell, it prevents excessive clamping force that could damage the battery cell. When the closing slide closes the individual battery cells in the group, the clamping block assembly detects sudden changes in clamping force in a timely manner to prevent excessive clamping force that could damage the battery cell during closing and positioning. (3) During operation, the pressure probe senses whether the clamping plate is in contact with itself, thereby calibrating the position of the clamping plate and then calibrating the value of the clamping force. The transmission worm is rotated by the knob, so that the transmission worm wheel rotates accurately, thereby accurately calibrating the position of the pressure probe and thus accurately calibrating different clamping forces. The threaded sleeve slides in the through groove and is stably slid by the third slide rod, thereby keeping the position of the pressure probe stable. The self-locking property of the worm wheel structure is used to avoid the slight rotation of the threaded sleeve, thereby keeping the clamping force accurate and consistent each time. Combined with the elastic coefficient and number of the return spring, the clamping force of the two clamping plates is quantitatively set. The value set by the sensing component is the maximum value of the clamping force, thereby accurately limiting the clamping force from exceeding the set value. During clamping, the clamping plate pushes each second slide rod to move synchronously, synchronously stretching each return spring. The spring force of each return spring is the same through the circular array distribution, thereby keeping the clamping force accurate and consistent each time and within a safe range.

[0020] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0021] Please see Figure 1-6As shown: A clamping and transfer device for lithium battery production and processing includes a three-axis slide table 101. A clamping mechanism 201 is mounted on the working end of the three-axis slide table 101. The clamping mechanism 201 includes a lifting slide table 202. A first motor 205 is mounted on the lower end of the lifting slide table 202. A clamping assembly 301 is mounted on the lower end of the rotating shaft of the first motor 205. The clamping assembly 301 includes a transmission box 302. Transmission sliders 303 are slidably connected to both sides inside the transmission box 302. A transmission rack 304 is mounted on one end of each transmission slider 303. Each transmission rack 304 is fixedly connected to its corresponding transmission slider 303 and movably passes through the end of another transmission slider 303. The two transmission racks 304 and the two transmission sliders 303 are centrally symmetrical. A second motor 305 is provided at the center of symmetry of the two transmission racks 304. A transmission gear cylinder 306 is installed at the lower end of the drive shaft of the second motor 305. The transmission gear cylinder 306 is meshed with both transmission racks 304. A detection probe 312 is provided between the transmission gear cylinder 306 and the two transmission sliders 303. In this embodiment, the second motor 305 rotates the transmission gear cylinder 306, synchronously driving the two transmission racks 304, causing the two transmission sliders 303 to move symmetrically towards the midpoint of the transmission box 302 until they clamp the two sides of the battery cell. At the same time, the detection probe 312 can make precise contact with and electrically connect to the electrodes of the battery cell. The positive and negative poles of the battery cell can be obtained based on the positive and negative potential detected by the detection probe 312, and the electrical energy parameters of the battery cell can be obtained simultaneously. The quality of the produced battery cell can be detected simultaneously. Then, according to the design requirements, the first motor 205 rotates the clamping assembly 301 to adjust the position of the positive and negative poles of the battery cell, preparing for the subsequent processing steps. When grouping the battery cells, the clamping mechanism 201 is moved by the three-axis slide table 101, thereby realizing the simultaneous and flexible adjustment of the battery cell position and detection of the battery cell's electrical energy parameters, simplifying the overall process and improving work efficiency.

[0022] Both ends of the slider of the lifting slide 202 are hinged with diagonal bracing rods 204. Both sides of the first motor 205 are hinged with closing slides 203. The two closing slides 203 are coaxial, and the axial direction of the closing slides 203 is perpendicular to the axial direction of the clamping assembly 301. The middle part of the upper surface of the closing slide 203 is hinged to the lower end of the diagonal bracing rods 204. The middle part of the lower surface of the transmission slider 303 and the moving end of the closing slide 203 are both equipped with clamping block assemblies 401. In this embodiment, the two closing slides 203 are extended to a horizontal state to close and position the grouped battery cells. When not closed, the closing slides 203 are retracted by the lifting slides 202 to avoid interfering with the movement of the battery cells. The clamping block assembly 401 is closed synchronously by the two closing slides 203, so that adjacent battery cells in the group abut against each other and cooperate with the second transfer belt 103 to adjust the position of the battery cells in adjacent groups. The clamping block assembly 401 detects and samples the clamping force in a timely manner when clamping and closing. When the clamping assembly 301 clamps the battery cell, it avoids excessive clamping force on the battery cell and damages it. When the closing slides 203 close the individual battery cells in the group, the clamping block assembly 401 detects sudden changes in clamping force in a timely manner to avoid excessive clamping force on the battery cell and damage during closing and positioning.

[0023] A support block 310 is provided between the transmission slider 303 and the transmission gear cylinder 306. A detection slider 309 is fixedly connected to the middle of both sides of the support block 310. A first slide rod 308 is movably passed through the middle of the detection slider 309. Limit springs 313 are movably sleeved on both sides of the first slide rod 308. One end of the first slide rod 308 near the transmission gear cylinder 306 is mounted on the transmission box 302 through a positioning block 307. The other end of the first slide rod 308 movably passes through the transmission slider 303. A telescopic probe 311 is installed on the lower surface of the support block 310, and a detection probe 312 is installed at the lower end of the telescopic probe 311. In this embodiment, the position of the detection probe 312 in the horizontal direction is limited by the limiting spring 313. When the transmission slider 303 moves to different positions to clamp battery cells of different sizes, the elastic force generated by the contraction of the limiting spring 313 makes the detection slider 309 always follow the movement of the transmission slider 303 on the first slide rod 308. The position of the detection probe 312 in the vertical direction is adapted by the telescopic probe rod 311 to avoid damage to the electrodes by the detection probe 312. Thus, it can be adapted to the electrode positions of different battery cells, can adapt to different battery cells, and can replace the limiting spring 313 with different elasticity to further adapt to battery cells with different electrode positions, producing a better following effect and adapting to more types of battery cells.

[0024] The second motor 305 is equipped with mounting bases 314 on all four sides. A limiting rod 315 is provided on one side of the mounting base 314, and the mounting base 314 is elastically hinged to the limiting rod 315 through a torsion spring shaft 316. A friction block 317 is fixedly connected to the side of the limiting rod 315 near the transmission gear cylinder 306. A permanent magnet block 318 is installed on the other side of the limiting rod 315. An electromagnet 319 is installed on the outer wall of the second motor 305 near the permanent magnet block 318. In this embodiment, when the second motor 305 stops rotating the transmission gear cylinder 306, the electromagnet 319 starts and pushes the permanent magnet block 318, thereby causing the friction block 317 to rub against the transmission gear cylinder 306, keeping the transmission gear cylinder 306 stationary. This works in conjunction with the second motor 305 to improve the accurate positioning of the clamping block assembly 401 and the accurate generation of clamping force, while avoiding damage to the second motor 305 and maintaining an accurate clamping force. This allows for quick clamping of the battery cell while ensuring that the clamping force remains controllable and consistent for each clamping, preventing damage to the battery cell and reducing the duration of each clamping operation.

[0025] The clamping block assembly 401 includes a positioning seat 402. A support plate 403 is fixedly connected to one side of the lower surface of the positioning seat 402, and a clamping plate 404 is slidably connected to the other side of the lower surface of the positioning seat 402. A sensing component 501 is fixedly inserted through the middle of the support plate 403. Several second slide rods 405 are arranged around the sensing component 501. Each second slide rod 405 is evenly distributed in a circular array with the sensing component 501 as the center. One end of the second slide rod 405 is fixedly connected to the clamping plate 404, and the other end of the second slide rod 405 movably passes through the support plate 403. A return spring 407 is movably sleeved on the other end of the second slide rod 405. One end of the return spring 407 is fixedly connected to the support plate 403, and the other end of the return spring 407 is fixedly connected to a connecting plate 406. The connecting plate 406 is fixedly connected to the second slide rod 405. In this embodiment, the moving distance of the clamping plate 404 is quantitatively set by the sensing component 501, and combined with the elastic coefficient and number of the return springs 407, the clamping force of the two clamping plates 404 is quantitatively set. The value set by the sensing component 501 is the maximum value of the clamping force, thereby accurately limiting the clamping force from exceeding the set value. During clamping, the clamping plate 404 pushes each of the second slide bars 405 to move synchronously, and synchronously stretches each of the return springs 407. The spring force of each return spring 407 is the same through the circular array distribution, thereby keeping the clamping force accurate and consistent and within a safe range during each clamping.

[0026] The sensing component 501 includes a mounting box 502. A through groove 503 is provided in the middle of the inner side of the mounting box 502. A threaded sleeve 504 is movably inserted in the through groove 503. One end of the threaded sleeve 504 movably passes through one end of the mounting box 502. A pressure probe 510 is installed at one end of the threaded sleeve 504. A transmission screw 505 is threadedly connected to the other end of the threaded sleeve 504. A transmission worm gear 507 is fixedly sleeved at the end of the transmission screw 505. A worm gear cavity 506 is provided on the inner side of the end of the mounting box 502 and on the outer periphery of the transmission worm gear 507. A transmission worm 508 is meshed on one side of the transmission worm gear 507. The transmission worm 508 is rotatably connected to the mounting box 502. One end of the transmission worm 508 passes through the mounting box 502 and is equipped with a knob. A third slide rod 509 is installed on both sides of the pressure probe 510. The third slide rod 509 movably passes through the mounting box 502. In this embodiment, the pressure probe 510 senses whether the clamping plate 404 is in contact with itself, thereby calibrating the position of the clamping plate 404 and thus calibrating the clamping force value. By rotating the knob, the transmission worm 508 is rotated, causing the transmission worm wheel 507 to rotate accurately, thereby accurately calibrating the position of the pressure probe 510 and accurately calibrating different clamping forces. The threaded sleeve 504 slides in the through groove 503, and the third slide rod 509 stabilizes the position of the pressure probe 510. The self-locking property of the worm wheel structure prevents slight rotation of the threaded sleeve 504, thus ensuring that the clamping force is accurate and consistent for each clamping operation.

[0027] A first transfer belt 102 and a second transfer belt 103 are arranged parallel to each other below the three-axis slide table 101. A multi-axis spot welding machine and a strapping machine are located at the end of the second transfer belt 103. The manufactured battery cells are moved one by one to the area below the three-axis slide table 101 via the first transfer belt 102. Then, the three-axis slide table 101 moves the clamping mechanism 201, and the battery cells are moved one by one onto the second transfer belt 103 via the three-axis slide table 101 and the clamping mechanism 201. During the movement, the positive and negative terminals of the battery cells are detected, and the distribution of positive and negative terminals of adjacent battery cells is adjusted according to the battery design requirements to facilitate subsequent series and parallel connections. After welding, the cells are grouped and assembled into several groups that abut against each other on the second transfer belt 103 according to the battery size requirements via a three-axis slide 101 and a clamping mechanism 201. The cells in each adjacent group are kept at a certain distance by cooperating with the second transfer belt 103. This ensures that the midpoint distance between adjacent groups of cells is consistent, as well as the outer circumference distance between adjacent groups of cells. This facilitates the series and parallel welding of the cells by the spot welding machine and the bundling of the cells by the bundling machine. As a result, this device can produce lithium batteries of different specifications in the same batch, realizing the personalization and intelligentization of lithium battery production.

[0028] In use, the operator rotates the transmission gear cylinder 306 via the second motor 305, simultaneously driving the two transmission racks 304. This causes the two transmission sliders 303 to move symmetrically towards the midpoint of the transmission box 302 until they clamp the two sides of the battery cell. A limiting spring 313 limits the horizontal position of the detection probe 312. When the transmission sliders 303 move to different positions to clamp battery cells of different sizes, the limiting spring 313, through its contraction, generates elastic force that keeps the detection slider 309 on the first slide rod 308, following the movement of the transmission sliders 303. The telescopic probe rod 311 adapts the vertical position of the detection probe 312 to prevent damage to the electrodes. This allows it to adapt to the electrode positions of different battery cells, dynamically adapt to different battery cells, and further adapt to battery cells with different electrode positions by replacing the limit springs 313 with different elasticity. The positive and negative poles of the battery cell are obtained according to the positive and negative potential detected by the detection probe 312, and the electrical energy parameters of the battery cell can be obtained at the same time. The quality of the produced battery cells can be detected simultaneously. Then, according to the design requirements, the clamping assembly 301 is rotated by the first motor 205 to adjust the positive and negative pole positions of the battery cell, preparing for the subsequent processing steps. When the battery cells are grouped, the clamping mechanism 201 is moved by the three-axis slide table 101, thereby realizing the two steps of flexibly adjusting the position of the battery cell and detecting the electrical energy parameters of the battery cell at the same time, simplifying the overall process and improving work efficiency. During operation, the two closing slides 203 are extended to a horizontal position to close and position the grouped battery cells. When not closed, the closing slides 203 are retracted via the lifting slide 202 to avoid interfering with the movement of the battery cells. The clamping block assembly 401 is closed synchronously by the two closing slides 203, so that adjacent battery cells in the group abut against each other. This works in conjunction with the second transfer belt 103 to adjust the position of the battery cells in adjacent groups. When the second motor 305 stops rotating the transmission gear cylinder 306, the electromagnet 319 is activated and pushes the permanent magnet block 318, which in turn causes the friction block 317 to rub against the transmission gear cylinder 306, keeping the transmission gear cylinder 306 stationary and in contact with the second motor 305. In conjunction with the clamping block assembly 401, the accuracy of positioning and clamping force generation is improved, and damage to the second motor 305 is avoided. The clamping force is kept accurate, so that the battery cell can be clamped quickly and the clamping force can be kept controllable and consistent for each clamping, thus avoiding damage to the battery cell and reducing the clamping time. The clamping block assembly 401 detects and samples the clamping force in a timely manner when clamping and closing. When the clamping assembly 301 clamps the battery cell, it avoids excessive clamping force on the battery cell, which could damage the battery cell. When the closing slide 203 closes the individual battery cells in the group, the clamping block assembly 401 detects sudden changes in clamping force in a timely manner, thus avoiding excessive clamping force on the battery cell during closing and positioning, which could damage the battery cell. During operation, the pressure probe 510 senses whether the clamping plate 404 is in contact with itself, thereby calibrating the position of the clamping plate 404 and thus determining the clamping force value. Rotating the knob on the transmission worm gear 508 causes the transmission worm wheel 507 to rotate accurately, further calibrating the position of the pressure probe 510 and thus accurately determining different clamping forces. The threaded sleeve 504 slides within the through groove 503, and the third slide rod 509 stabilizes the position of the pressure probe 510, maintaining stability. The self-locking property of the worm gear structure prevents minor slippage of the threaded sleeve 504. The clamping force is rotated to maintain a consistent and accurate clamping force for each clamping operation. Combined with the elastic coefficient and number of the return springs 407, the clamping force of the two clamping plates 404 is quantitatively set. The value set by the sensing component 501 is the maximum value of the clamping force, thereby accurately limiting the clamping force from exceeding the set value. During clamping, the clamping plates 404 push each of the second slide bars 405 to move synchronously, synchronously stretching each of the return springs 407. The spring force of each return spring 407 is the same through a circular array distribution, thereby maintaining a consistent and safe clamping force for each clamping operation.
