[0001] This invention relates to the field of batteries, and in particular to a CCS product welding inspection production line and a welding inspection method using the same. Background Technology

[0002] The CCS components used in new energy battery modules are generally composed of busbars, blister packs, and nickel sheets welded together. During the production process, electrical performance tests are often required after welding to determine the product processing effect. These tests mainly include insulation, withstand voltage, and temperature sensitivity tests; as well as inspection of welding and hot riveting, including poor welding, poor hot riveting, multi-layer nickel sheets, multi-layer busbars, and whether connector pins are bent.

[0003] The welding and testing processes described above are generally carried out using multiple machines, and workers need to manually transfer CCS components between the machines, which is time-consuming and labor-intensive, reducing production efficiency and yield. Summary of the Invention

[0004] According to one aspect of the present invention, a welding inspection production line for CCS products and a welding inspection method thereon are provided, comprising a feeding device, a welding device, an electrical performance testing device, a welding inspection device and a unloading device arranged in parallel from front to back, wherein the welding device, the electrical performance testing device and the welding inspection device are provided with two conveying tracks extending from front to back, and conveying plates are placed on the conveying tracks.

[0005] The feeding equipment includes a feeding machine platform, the conveying plate is placed in the middle of the feeding machine platform and can move back and forth and rise and fall, and the upper part of the feeding machine platform is equipped with multiple matrix cameras capable of three-axis motion, and the lens of each matrix camera is facing the conveying plate below.

[0006] The welding equipment includes a welding machine platform, on which two welding structures capable of three-axis motion are installed side by side. A laser welding head with a built-in galvanometer is installed on the upper part of the welding structure, and a welding pressure block capable of lifting and lowering is installed on the lower part.

[0007] The electrical performance testing equipment includes an electrical performance testing platform, on which multiple rows and columns of probe holders capable of lifting, lowering, and moving left and right are installed, and each probe holder is equipped with multiple test probes.

[0008] The welding inspection equipment includes a welding inspection machine, on which at least one three-dimensional camera and at least one two-dimensional line scan camera capable of two-axis horizontal movement are mounted, as well as a pin inspection camera capable of three-axis movement.

[0009] The structure of the unloading device is the same as that of the loading device, but it does not include the matrix cameras.

[0010] The present invention discloses a CCS product welding and inspection production line, which places CCS component loading equipment, welding equipment, electrical performance testing equipment, welding inspection equipment, and unloading equipment side by side. The CCS components can be automatically transferred between the equipment, thereby realizing the processes of loading, welding, electrical performance testing, welding inspection, and unloading of CCS components, saving time and labor, and improving the efficiency and yield of CCS component production and processing.

[0011] In some embodiments, the feeding equipment, the welding equipment, the electrical performance testing equipment, and the welding inspection equipment are all equipped with outer covers. The advantage of this is that the outer covers can provide a certain degree of isolation and protection for each piece of equipment.

[0012] In some embodiments, the welding equipment, the electrical performance testing equipment, and the welding inspection equipment are also provided with two additional, front-to-back conveyor tracks at their bottoms. This is advantageous because the lower conveyor tracks allow empty conveyor plates to flow back from below to the loading equipment.

[0013] In some embodiments, the feeding machine platform has two double-speed chains extending forward and backward in the middle. Both chains are mounted on a lifting platform, and two vertical lifting screws are mounted on the left and right sides of the lifting platform. These lifting screws are connected to the same lifting motor via two sprocket transmission mechanisms. The advantage of this design is that it enables the lifting and movement of the conveyor plate.

[0014] In some embodiments, multiple horizontally extending camera slides are mounted side-by-side on the upper part of the conveyor plate, and each matrix camera is mounted on the camera slide via a three-axis mounting bracket. The advantage of this is that it enables three-axis movement of the matrix cameras.

[0015] In some embodiments, the welding machine is provided with multiple left-right extending X-axis welding slides at both the front and rear ends. Two Y-axis welding slides are slidably mounted on each X-axis welding slide, and two Z-axis welding slides are slidably mounted on each Y-axis welding slide. Each welding structure is mounted on one of the two Z-axis welding slides. The advantage of this is that it enables the movement of each welding structure.

[0016] In some embodiments, the welding structure includes a mounting plate, with the laser welding head mounted on the upper part of the mounting plate. A vertical slide rail and a pressure cylinder are respectively mounted on both sides of the lower part of the mounting plate. The welding block is slidably mounted on the vertical slide rail and connected to the pressure cylinder. Its advantage lies in describing the specific structure of the welding structure, enabling both pressure application and welding.

[0017] In some embodiments, the electrical performance testing machine has two left-right extending downward mounting brackets at its front and rear ends, respectively. Each mounting bracket has a downward servo cylinder mounted on its upper part and a left-right extending downward rod movably mounted on its lower part. The rotor at the bottom of the downward servo cylinder is connected to the downward rod, and the bottoms of the two downward rods are slidably connected to a probe fixture assembly. Each probe holder is mounted on the probe fixture assembly. Its advantage lies in enabling horizontal and vertical movement of the probe fixture assembly and each probe holder.

[0018] In some embodiments, the probe fixture assembly includes multiple probe mounting crossbars arranged side-by-side and extending front-back. Each probe mounting crossbar is slidably connected to the bottom of two pressure rods, and multiple probe mounting longitudinal bars extending left-right are connected to the bottom of each probe mounting bracket. Each probe seat is slidably mounted side-by-side on the bottom of each probe mounting longitudinal bar. Its advantage lies in describing the specific structure of the probe fixture assembly, allowing for various tests to be performed using each probe.

[0019] In some embodiments, the bottoms of the two pressure rods are also slidably connected to a pin testing assembly. The advantage of this is that the pin testing assembly is used to perform electrical performance testing on the pins of each plug on the product.

[0020] In some embodiments, the welding inspection machine is equipped with a horizontally extending marble linear motor. A horizontally extending detection slide is slidably mounted on the marble linear motor. A detection frame is slidably mounted on one side of the horizontal detection slide, and both the 3D camera and the 2D line scan camera are mounted on the detection frame. A vertical detection slide is slidably mounted on the other side of the horizontal detection slide, and the pin detection camera is slidably mounted on the vertical detection slide. Its advantage lies in further describing the specific structure of the welding inspection machine, enabling movement of each camera.

[0021] In some embodiments, the welding machine, the electrical performance testing machine, and the welding inspection machine are all equipped with lifting mechanisms. The advantage of this is that the lifting mechanisms can lift the material handling plate and its tooling trays and products to facilitate the operation of each piece of equipment.

[0022] According to another aspect of the present invention, a welding inspection method is provided that utilizes the above-mentioned CCS product welding inspection production line, comprising the following steps:

[0023] S1: Place the tooling tray containing the CCS components and nickel sheets onto the conveying plate of the feeding equipment, and use each of the matrix cameras for detection;

[0024] S2: Place each material conveying plate onto each of the material conveying tracks and move them to the welding equipment. First, use the welding pressure block to press the nickel sheet, and then use the laser welding head to measure distance and weld.

[0025] S3: Move the feeding plate to the electrical performance testing equipment and use each of the test probes to perform electrical performance testing on the nickel sheet;

[0026] S4: Move the material conveying plate to the welding inspection equipment and perform inspection using each of the three-dimensional cameras, each of the two-dimensional line scan cameras and the pin inspection camera;

[0027] S5: Transfer the conveyor plate to the unloading device for unloading.

Detailed Implementation

[0040] The present invention will now be described in further detail with reference to the accompanying drawings.

[0041] like Figure 1-3 As shown, the welding inspection line includes a feeding device 100, a welding device 200, an electrical performance testing device 300, a welding inspection device 400, and a unloading device arranged side by side from one end (referred to as the front end, the opposite end as the rear end, and the other two sides as the left and right sides) to the other end. These devices are used to feed, weld, perform electrical performance testing, weld inspection, and unload the CCS components 13 and nickel sheets 14 mounted on the tooling tray 12, respectively.

[0042] Two material conveying tracks 10 extending forward and backward are laid on the welding equipment 200, the electrical performance testing equipment 300 and the welding inspection equipment 400. Material conveying plates 11 that can move along the material conveying tracks 10 are placed on the material conveying tracks 10, and tooling trays 12 are placed on the material conveying plates 11.

[0043] Preferably, the feeding equipment 100, welding equipment 200, electrical performance testing equipment 300 and welding inspection equipment 400 are all equipped with outer covers for a certain degree of isolation and protection.

[0044] Two CCS assemblies 13 (including busbars and flexible circuit boards FPC) are placed side by side on a tooling tray 12. Multiple nickel strips 14 need to be soldered on each CCS assembly 13, and each of the two CCS assemblies 13 has a pin-connected plug 15 on one side.

[0045] In addition, two other material conveying tracks 10 extending forward and backward are laid together at the bottom of the welding equipment 200, the electrical performance testing equipment 300 and the welding inspection equipment 400, for the return of the material conveying plate 11 of the hole after material feeding.

[0046] like Figure 4 As shown, the feeding device 100 includes a feeding platform 110, and the middle of the feeding platform 110 can be used to set the conveying plate 11. The bottom surface of the conveying plate 11 is placed on the left and right sides of two front-to-back double-speed chains 120 respectively, and can move back and forth under the operation of the two double-speed chains 120.

[0047] Two double-speed chains 120 are both installed on a lifting platform 130. The left and right sides of the lifting platform 130 are respectively installed on two vertical lifting screws 140. The bottom of the two lifting screws 140 is connected to the same lifting motor 150 through two sprocket transmission mechanisms 160. The operation of the lifting motor 150 can drive the two lifting screws 140 to rotate, thereby further driving the lifting platform 130 and the material conveying plate 11 on it to lift.

[0048] In addition, multiple horizontally extending camera slides 180 are mounted side-by-side on the lower side of the top plate of the outer casing of the feeding equipment 100. At the bottom of the camera slides 180, multiple matrix cameras 170 capable of XYZ three-axis movement are mounted side-by-side via a three-axis mounting bracket 190. The three-axis mounting bracket 190 is equipped with corresponding cylinders and slide rails for each axis of movement. The lenses of each matrix camera 170 face the lower conveyor plate 11, which can be used to monitor the feeding of CCS components 13 and nickel sheets 14 on the tooling tray 12, such as whether there is misalignment or omission during feeding.

[0049] The unloading equipment and the loading equipment 100 have the same structure in some parts, including the machine base, conveying plate 11, double speed chain 120, lifting platform 130, lifting screw 140, lifting motor 150, and sprocket transmission mechanism 160, but do not have the camera slide 180, three-axis mounting frame 190 and matrix camera 170.

[0050] like Figure 5-6 As shown, the welding equipment 200 includes a welding platform 210, with a material conveying plate 11 placed in the center of the welding platform 210. Multiple left-right extending X-axis welding slides 230 are provided at both the front and rear ends of the welding platform 210. Two Y-axis welding slides 240 are slidably mounted on each X-axis welding slide 230, and two Z-axis welding slides 250 are slidably mounted on each Y-axis welding slide 240. A welding structure 220 is mounted on each Z-axis welding slide 250. Thus, the welding structure 220 can achieve three-axis motion.

[0051] The welding structure 220 includes a mounting plate 223. A laser welding head 221 is mounted on the upper part of the mounting plate 223, and a lifting welding block 222 is mounted on the lower part. The welding block 222 is located directly below the laser welding head 221 and has a hollow structure so as not to affect the welding of the laser welding head 221. A vertical slide rail 224 and a pressing cylinder 225 are respectively mounted on both sides of the lower part of the mounting plate 223. The welding block 222 is mounted on the vertical slide rail 224 and connected to the piston rod of the pressing cylinder 225. It can slide along the vertical slide rail 224 under the operation of the pressing cylinder 225 to press the product to be welded on the tooling tray 12. The laser welding head 221 has a built-in galvanometer and is equipped with vision and distance sensors, which can be used for product photography, distance measurement, and welding.

[0052] like Figure 7-8 As shown, the electrical performance testing equipment 300 includes an electrical performance testing platform 310, and the material conveying plate 11 can be placed in the center of the electrical performance testing platform 310. The electrical performance testing platform 310 has two left-right extending downward mounting brackets 330 at its front and rear ends, respectively. Each downward mounting bracket 330 has a downward servo cylinder 331 mounted on its upper part and a left-right extending downward rod 332 movably mounted on its lower part. The rotor at the bottom of the downward servo cylinder 331 is connected to the downward rod 332, and the bottoms of the two downward rods 332 are slidably connected to a probe fixture assembly 320. Therefore, the operation of the downward servo cylinder 331 can drive the downward rods 332 and the probe fixture assembly 320 to rise and fall.

[0053] The probe fixture assembly 320 includes multiple probe mounting crossbars 323 arranged side-by-side and extending front-back. Each probe mounting crossbar 323 is slidably connected to the bottom of two pressure rods 332. Multiple probe mounting longitudinal rods 324 extending left-right are connected to the bottom of each probe mounting bracket. Multiple probe holders 321 are slidably mounted side-by-side at the bottom of each probe mounting longitudinal rod 324, and multiple test probes 322 are mounted on each probe holder 321 (four are used as an example in this embodiment). When the probe mounting crossbars 323 slide along the pressure rods 332, they can simultaneously slide the test probes 322. Combined with the lifting and lowering of the probe fixture assembly 320, insulation, withstand voltage, and temperature sensitivity tests can be performed on each product.

[0054] In addition, a pin test assembly 340 is slidably connected to the bottom of the two pressure rods 332. The pin test assembly 340 can perform electrical performance tests on the pins of each plug 15 on the product, and all test results are uploaded to the processor.

[0055] like Figure 9-10 As shown, the welding inspection equipment 400 includes a welding inspection platform 410, and the material conveying plate 11 can be placed in the center of the welding inspection platform 410. A marble linear motor 450 with a certain height and extending left and right is installed on the welding inspection platform 410, and a horizontal inspection slide 460 extending front and back is slidably installed on the marble linear motor 450.

[0056] A detection frame 470 is slidably mounted on one side of the horizontal detection slide 460. At least one 3D camera 420 is mounted on the upper part of the detection frame 470, and at least one 2D line scan camera 430 is mounted on the lower part. The lenses of the 3D camera 420 and the 2D line scan camera 430 are both facing downwards and are used to detect the welding effect, such as whether there is any missing weld or poor welding. On the other side of the horizontal detection slide 460, a vertical detection slide 480 is slidably mounted. A pin detection camera 440 is slidably mounted on the vertical detection slide 480 to detect whether the pins of the plug 15 are broken or bent. The detection results of each camera are uploaded to the processor.

[0057] In addition, lifting mechanisms (not shown in the figure) are provided on the feeding machine 110, the electrical performance testing machine 310 and the welding inspection machine 410. The lifting mechanisms are located below the conveying plate 11 and can lift the conveying plate 11 and the tooling tray 12 and products on it to cooperate with the operation of each piece of equipment.

[0058] When using this welding inspection line to perform welding inspection on CCS products, the workflow mainly includes the following steps:

[0059] S1, Loading: Place the tooling tray 12 carrying the CCS component 13 and nickel sheet 14 on the conveying plate 11 of the loading equipment 100, use each matrix camera 170 to detect whether there is any misalignment or omission, then place the conveying plate 11 onto the two conveying tracks 10, and then move it to the welding equipment 200.

[0060] S2, Welding: Move the material conveying plate 11 to the welding machine table 210 of the welding equipment 200, each laser welding head 221 moves in three axes, and in sequence, the welding pressure block 222 is lowered and pressed to each welding position, and then the laser welding head 221 is used to take pictures, measure distances and weld.

[0061] S3, Electrical performance test: Move the material conveyor plate 11 to the electrical performance test machine 310 of the electrical performance test equipment 300, use the test probes 322 on each probe tooling assembly 320 to perform insulation, withstand voltage, temperature sensitivity and other tests on each product, and use the pin test assembly 340 to test the pins of each plug 15 on the product.

[0062] S4, Welding Inspection: Move the material conveying plate 11 to the welding inspection table 410 of the welding inspection equipment 400, use each three-dimensional camera 420 and each two-dimensional line scan camera 430 to inspect the welding effect of the product, and use the pin inspection camera 440 to inspect the pins of the plug 15.

[0063] S5, Unloading: Transfer the conveyor plate 11 after inspection to the unloading equipment, and unload the product according to the inspection results;

[0064] S6, Return: The empty conveyor plate 11 after unloading is returned from the bottom to the feeding device 100.

[0065] The above descriptions are merely some embodiments of the present invention. Those skilled in the art can make various modifications and improvements without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
