[0042] The supporting legs 101 provide stable support for the assembly cavity 1 , and the supporting plate 103 can be stably supported and connected to the assembly cavity 1 through the connecting rod 102 , and the supporting plate 103 is used as a base for the stable operation of the supporting frame 2 .

[0043] A movable frame 201 is movably mounted on the middle of the outer surface of the support frame 2, an electric push rod 202 is fixedly mounted on the middle of the lower surface of the movable frame 201, the other end of the electric push rod 202 penetrates the support plate 103 and is fixedly connected to the middle of the inner bottom surface of the assembly cavity 1, a battery 3 is fixedly mounted on the inner surface of the movable frame 201, a pole piece scanning probe 4 is fixedly mounted on the middle of the front end of the outer surface of the movable frame 201, and the lens end of the pole piece scanning probe 4 is concavely arranged, a sonic welding hand 5 is fixedly mounted on the middle of the rear end of the outer surface of the movable frame 201, and an integrated controller 6 is fixedly mounted on the upper surface of the movable frame 201;

[0044] The movable frame 201 is controlled to move up and down along the support frame 2 by controlling the electric push rod 202 to perform telescopic operation, and the battery is used to provide operating energy for the pole piece scanning probe 4 and the integrated controller 6. When the pole piece scanning probe 4 contacts the pole piece, it can wrap it, so that the pole piece can be comprehensively identified and scanned by the concave lens, and the side dimension frame of the pole piece and the measuring matrix 1301, as well as the horizontal line dimension frame of the upper surface of the measuring matrix 1301 and the upper surface of the pole piece are extracted, and the measurement data is obtained and transmitted to the integrated controller 6. The integrated controller 6 processes the measurement data to obtain corresponding signal instructions to control the operation of the entire processing equipment, and the pole piece and the lithium battery are ultrasonically welded by the ultrasonic welding hand 5 to complete the welding process of the lithium battery pole ear.

[0045] A motor 7 is fixedly installed at the front end of the bottom surface of the assembly cavity 1, and a transmission gear 701 is fixedly installed at the output end of the motor 7. A processing disk 8 is embedded and installed on the upper surface of the assembly cavity 1. The inner ring surface of the processing disk 8 contacts the outer ring surface of the support disk 103. A transmission gear ring 801 is fixedly provided on the lower surface of the processing disk 8. The transmission gear ring 801 and the transmission gear 701 are arranged in a mutually meshing state. A plurality of assembly openings 802 are opened in an annular shape through the upper surface of the processing disk 8. The plurality of assembly openings 802 are arranged in an interlaced shape with the movable shaft seat 9. A plurality of welding tables 13 are installed in an annular shape on the upper surface of the processing disk 8. The upper surface of the welding table 13 protrudes from the upper surface of the processing disk 8. An assembly block 1302 is fixedly provided on the lower surface of the welding table 13. The assembly block 1302 is inserted and installed in the assembly opening 802. Measuring blocks 1301 are fixedly provided on both sides of the middle part of the upper surface of the welding table 13. The size of the measuring blocks 1301 is larger than the size of the pole ear.

[0046] By starting the motor 7, the transmission gear 701 set at its output end is driven to rotate clockwise and counterclockwise. The transmission gear 701 and the transmission gear ring 801 are arranged in a mutually meshing state. The clockwise and counterclockwise rotation of the transmission gear 701 drives the transmission gear ring 801 to rotate clockwise and counterclockwise, thereby driving the processing disk 8 to rotate and adjust with the support disk 103 as the center point. The assembly block 1302 is inserted into the assembly port 802 to facilitate the insertion, installation and replacement of the welding table 13 on the processing disk 8. The assembly port 802 and the movable shaft seat 9 are staggered to avoid mutual interference between the movable shaft seat 9 and the welding table 13. The welding table 13 is protruded from the processing disk 8 to facilitate the welding operation of the pole piece under the ultrasonic welding hand 5. The measuring moment block 1301 is used to refer to the size of the pole piece and is used as a reference standard.

[0047] The upper surface of the processing disk 8 is evenly arranged with a number of movable shaft seats 9 installed in a ring shape, and the upper and lower parts of the outer surface of the movable shaft seat 9 are scissor-type movably sleeved with a clamping plate 901, and the middle part of the inner side of the clamping plate 901 is fixed with a guide groove 902, and the clamping plate 901 is movably inserted and installed with a support plate 903 through the inner surface of the guide groove 902, and the front end of the outer surface of the support plate 903 is spirally penetrated and inserted and installed with an adjusting screw 1002, and the end of the adjusting screw 1002 away from the movable shaft seat 9 is fixedly installed with a motor 10, and the outer surface of the motor 10 is sleeved with a fixing ring 1001, and the fixing ring 1001 is fixedly connected to the upper surface of the processing disk 8;

[0048] By starting the motor 10, the adjusting screw 1002 is controlled to rotate clockwise or counterclockwise. According to the rotation state of the adjusting screw 1002, the supporting plate 903 can be controlled to move laterally along the guide groove 902. The lateral movement of the supporting plate 903 is thereby utilized to control the spacing of the clamping plates 901 that expand in a fan shape with the movable shaft seat 9 as the center point, thereby achieving the purpose of adjusting the clamping spacing between the clamping plates 901, so as to achieve the effect of clamping and fixing lithium batteries of different specifications. The fixing ring 1001 is used to install and fix the motor 10 on the processing disk 8.

[0049] A scissor-type adjustment frame 11 is movably installed above the two adjacent clamping plates 901 on the outer side surfaces, and a positioning frame 1101 is movably installed at both ends of the scissor-type adjustment frame 11. The lower surface of the positioning frame 1101 is connected to the upper surface of the clamping plate 901. The adjacent ends of the scissor-type adjustment frames 11 are movably connected in series through a movable shaft, and a fixed block 12 is movably installed in the middle of the outer surface of the scissor-type adjustment frame 11 through the movable shaft;

[0050] The scissor-type adjustment frame 11 is movably connected to the clamping plate 901 through the positioning frame 1101. The closing and opening of the scissor-type adjustment frame 11 can be controlled by adjusting the clamping distance between two adjacent clamping plates 901. When the clamping distance of the clamping plates 901 is reduced, the scissor-type adjustment frame 11 will gradually close, thereby driving the fixing block 12 to press down. When the clamping distance of the clamping plates 901 is expanded, the scissor-type adjustment frame 11 will gradually open, thereby driving the fixing block 12 to rise, so as to be suitable for clamping and fixing lithium batteries of different specifications.

[0051] Both ends of the fixed block 12 are provided with receiving grooves 1201, and a limiting plate 1204 is movably inserted and installed on the inner surface of the receiving groove 1201 away from one end of the fixed block 12, and a compression spring 1202 is fixedly installed inside the receiving groove 1201, one end of the compression spring 1202 is connected to the inner surface of the receiving groove 1201 close to one end of the fixed block 12, and the other end of the compression spring 1202 is connected to the end of the limiting plate 1204 inserted into the receiving groove 1201, and limiting grooves 1203 are penetrated through the middle of the front end and the rear end of the outer surface of the receiving groove 1201, and a limiting block 1205 is movably installed on the inner surface of the limiting groove 1203, and the limiting block 1205 is connected to the outer surface of the limiting plate 1204 inserted into the inner end of the receiving groove 1201, and the end of the limiting plate 1204 away from the receiving groove 1201 is arranged in an inclined shape;

[0052] The upper surface of the lithium battery can be pressed and clamped by the fixing block 12, and the storage groove 1201 is used to store the limit plate 1204. When the clamping distance between the clamping plates 901 is reduced, the limit plate 1204 will be squeezed and contracted into the storage groove 1201. The limit block 1205 and the limit groove 1203 can be used together to limit the contraction process of the limit plate 1204 to avoid deviation. When the limit plate 1204 contracts into the storage groove 1201, the compression spring 120 2 causes squeezing and controls it to be compressed. When the clamping distance between the clamping plates 901 is enlarged, the squeezing force on the limit plate 1204 will be reduced and the pressure on the compression spring 1202 will be further reduced. In this case, the compression spring 1202 will use its own elasticity to start rebounding to control the limit plate 1204 to extend out of the storage slot 1201, and always keep its end in contact with the outer surface of the clamping plate 901, thereby limiting the fixing block 12 and maintaining its stability in the process of pressing and fixing the lithium battery.

[0053] The two sides of the upper surface of the integrated controller 6 are fixedly installed with warning lights 601, and the internal configuration of the integrated controller 6 includes a preset module, an analysis module, a control module and a signal module;

[0054] The preset module is used to preset the size frame gap between the side of the measuring block 1301 and the side of the pole piece, and the horizontal line size frame gap between the upper surface of the measuring block 1301 and the upper surface of the pole piece, to form a preset plane reference image and a preset side reference image, and obtain a preset reference image of the pole piece size measurement standard;

[0055] The specific analysis is as follows: the processing personnel input the length and width values ​​of the measuring moment block 1301 to construct the preset reference frame of the measuring moment block 1301, and at the same time input the length and width values ​​of the pole piece to construct the preset reference frame of the pole piece, select the same center point for the measuring moment block 1301 and the preset reference frame of the pole piece to overlap, and the preset plane reference image A1 is formed by the spacing between the preset reference frames, so as to obtain the preset reference image of the length and width size standard;

[0056] Secondly, set the upper surface horizontal line of the measuring moment block 1301 to input an arbitrary numerical preset baseline, and at the same time input the thickness value of the pole piece to take the preset reference line of its upper surface horizontal line, and take the preset reference line of its lower surface horizontal line. Select the same center point for the measuring moment block 1301 and the preset baseline of the pole piece to coincide, and the preset side reference image B1 is formed by the distance between the preset baseline and the preset reference line to obtain the preset reference image of the thickness dimension standard.

[0057] The analysis module analyzes the received comparative image data of the pole piece and the measurement matrix 1301, extracts the frame images of the pole piece and the measurement matrix 1301, constructs a real-time plane reference image, extracts the horizontal line images of the upper surface of the measurement matrix 1301 and the upper surface of the pole piece, constructs a real-time side reference image, matches the real-time plane and side reference images with the preset reference images, generates corresponding signal instructions based on the matching results, and transmits the signal instructions to the control module in a sequence of processing operations in a sequence;

[0058] The specific analysis is as follows: a plane frame image of the electrode to be welded and the measuring matrix 1301 at the same center point is obtained by the electrode scanning probe 4, and the frame of the electrode and the measuring matrix 1301 in the image is extracted to form a real-time plane reference image A2, and at the same time, a side frame image of the lower surface horizontal line of the electrode to be welded and the upper surface horizontal line of the measuring matrix 1301 at the same center point is obtained, and the frame of the electrode, the lower surface horizontal line of the measuring matrix 1301 and the upper surface horizontal line of the electrode in the image are extracted to form a real-time side reference image B2;

[0059] The borders of the real-time plane reference image A2 and the preset plane reference image A1 are set to different colors, and they are overlapped and matched. If A2=A1, it indicates that the real-time plane reference image A2 and the preset plane reference image A1 are completely overlapped. At the same time, the borders of the real-time side reference image B2 and the preset side reference image B1 are set to different colors, and they are overlapped and matched. If B2=B1, it indicates that the real-time side reference image B2 and the preset side reference image B1 are completely overlapped and are in a successful matching state. In this case, a qualified signal for pole piece measurement can be generated, and signal instruction ① is executed based on the qualified signal;

[0060] If A2≠A1 or B2≠B1, it indicates that the real-time plane and side reference diagrams do not overlap with the preset plane and side reference diagrams, and are in a matching failure state, indicating that there is an error in the pole ear size. In this case, a pole piece measurement failure signal can be generated, and signal instruction ② can be executed based on the failure signal.

[0061] The control module controls each actuator to execute corresponding instruction operations in sequence according to the instruction sequence number based on the received signal instruction, and the signal module transmits the control signal to each actuator;

[0062] The specific analysis is: if the signal instruction received by the control module is signal instruction ①, the corresponding execution operations are in order:

[0063] S1, control the prompt light 601 to show green light to indicate that the measurement is qualified, and control the sonic welding hand 5 to start welding the electrode and the lithium battery directly below it;

[0064] S2, after the welding is completed, the sonic welding hand 5 is controlled to stop running, and the electric push rod 202 is controlled to expand and push the movable frame 201 to move upward along the support frame 2, so as to drive the pole piece scanning probe 4 and the sonic welding hand 5 to move upward and away from the lithium battery;

[0065] S3, after the ultrasonic welding hand 5 is adjusted in position, the control motor 7 is started to drive the transmission gear 701 to rotate, and the transmission gear 701 rotates to control the transmission gear ring 801 to rotate and drive the processing disk 8 to control the clamping plate 901 that does not clamp the lithium battery to be adjusted to the bottom of the pole piece scanning probe 4, and the number of rotations of the transmission gear 701 is specifically set according to the distribution position of the clamping plate 901 on the processing disk 8;

[0066] S4, the clamping plate 901 without the lithium battery being clamped is rotated to the position directly below the pole piece scanning probe 4, and the lithium battery and pole piece combination to be welded is inserted into the clamping space of the clamping plate 901, and the electric push rod 202 is controlled to contract to drive the movable frame 201 to move downward along the support frame 2, until the pole piece scanning probe 4 completes the coverage of the pole piece and obtains the pole piece image data again, and the cycle operation is performed;

[0067] If the signal instruction received by the control module is signal instruction ②, the corresponding execution operations are as follows:

[0068] S11, control the prompt light 601 to show a red light to indicate that the measurement is unqualified, and control the electric push rod 202 to expand and push the movable frame 201 to move upward along the support frame 2, driving the pole piece scanning probe 4 and the sonic welding hand 5 to move upward and away from the lithium battery;

[0069] S12, remove the unqualified lithium battery and tab combination from the clamping plate 901, and replace it with a new lithium battery tab combination for measurement. If the measurement is qualified, execute signal instruction ①; if the measurement is unqualified, continue to execute signal instruction ②.

[0070] When the present invention is in use, first, the motor 10 is started according to the size data of the lithium battery to control the adjusting screw 1002 to rotate clockwise or counterclockwise. When the adjusting screw 1002 rotates clockwise, the supporting plate 903 can be controlled to move forward laterally along the guide groove 902. When the adjusting screw 1002 rotates counterclockwise, the supporting plate 903 can be controlled to move backward laterally along the guide groove 902. The rotating state of the adjusting screw 1002 is used to control the supporting plate 903 to move laterally along the guide groove 902, and the clamping distance of the clamping plate 901 is fanned out with the movable shaft seat 9 as the center point until the outer side surface of the clamping plate 901 is clamped and matched with the side edge of the lithium battery.

[0071] At the same time, by adjusting the clamping distance of two adjacent clamping plates 901, the closing and unfolding of the scissor-type adjustment frame 11 can be controlled. When the clamping distance of the clamping plates 901 is reduced, the scissor-type adjustment frame 11 will gradually close, thereby driving the fixed block 12 to perform a downward pressing operation. When the clamping distance of the clamping plates 901 is expanded, the scissor-type adjustment frame 11 will gradually unfold, thereby driving the fixed block 12 to perform an upward operation. The upper surface of the lithium battery can be pressed and clamped by the fixed block 12, and the lithium battery to be welded can be fully limited and fixed in cooperation with the clamping plates 901 to avoid the problem of displacement during the welding process.

[0072] Secondly, the measuring matrix 1301 of the corresponding measurement standard can be selected according to the size data of the electrode to be welded, and the corresponding welding table 13 can be selected and inserted into the assembly port 802 on the processing disk 8 using the assembly block 1302. At this time, the lithium battery and the electrode can be combined, the lithium battery can be inserted into the limited space between the clamps 901, and the electrode can be extended to the welding table 13. In this case, the equipment can be started, and the electric push rod 202 can be contracted to drive the movable frame 201 to move downward along the support frame 2 until the electrode scanning probe 4 completes the coverage of the electrode, obtains the electrode image measurement data and transmits it to the integrated controller 6. At this time, the integrated controller 6 processes and analyzes the measurement data, obtains the corresponding signal instruction, and controls the execution mechanism to complete the welding process of the lithium battery electrode ear according to the instruction content.

[0073] The above are only embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
