Description

Technical Field

[0001] This invention relates to the field of battery processing technology, and in particular to a CCS processing equipment and processing method. Background Technology

[0002] CCS is a key component in battery modules, mainly responsible for the electrical connection between cells, ensuring smooth current flow, thereby realizing the storage and release of electrical energy. CCS not only realizes the series and parallel connection of cells, but also integrates functions such as temperature sampling and voltage sampling. Through signal acquisition components such as FPC (flexible printed circuit board) or PCB (printed circuit board), it provides real-time data to BMS (battery management system).

[0003] In the existing CCS welding process, the components are usually placed on a welding fixture, and then the workers arrange the wires. During the wire arrangement process, the workers need to use wire crimping pliers to press the ends of the wire harness to ensure the stability of the subsequent welding process.

[0004] However, due to the large number of solder joints, a large number of crimping pliers are also required. After the soldering is completed, workers need to pry the crimping pliers off the wire harness one by one. This process is time-consuming and labor-intensive, especially when dealing with a large number of solder joints, which significantly reduces production efficiency.

[0005] Therefore, a CCS processing equipment and processing method are proposed to solve the above problems. Summary of the Invention

[0009] In the above technical solution, an upper spring is fixedly connected between the bottom end of the groove and the bottom end of the upper block, and a pair of lower springs are fixedly connected between the side wall of the T-shaped rod and the side wall of the limiting rod.

[0010] In the above technical solution, further, a limiting plate is fixedly connected to the side wall of the horizontal block, a pair of upper return springs are fixedly connected between the outer wall of the fixed frame and the limiting plate, a lower return spring is fixedly connected between the bottom end of the side groove and the outer wall of the vertical block, and several limiting springs are fixedly connected between the inner side of the bottom groove and the side wall of the limiting rod.

[0011] In the above technical solution, guide grooves are provided at both ends of the bottom groove, a guide plate is fixedly connected to the outer wall of the limiting rod relative to the inner side of the guide groove, and a pressing head is fixedly connected to the top of the vertical block.

[0012] In the above technical solution, the release mechanism further includes a drive motor, a pair of side plates are fixedly connected to the top of the base plate, a threaded rod is rotatably connected between the side plates, the drive motor is fixedly connected to the side wall of one of the side plates, the output end of the drive motor passes through the side wall of the side plate and is fixedly connected to the side wall of the threaded rod, a sliding frame is slidably connected to the top of the base plate laterally, and the threaded rod is threadedly connected to the inner side wall of the sliding frame, a push plate is slidably connected to the inner side of the sliding frame, three round rods are fixedly connected to the bottom end of the push plate, the bottom ends of the round rods pass through the bottom end of the sliding frame, and a plurality of release grooves are equidistantly opened on the top of the base plate, and the plurality of release grooves are inclined on the side away from the sliding frame.

At the same time, push the horizontal block and press the vertical block so that the wire pressing head squeezes the wire harnesses onto the connecting piece. Step 2: Loading the material. Then, place the welding fixture with the wires arranged in the placement groove and restrict the position of the welding fixture by the positioning mechanism. Then, the equipment can be started to automatically laser weld the wires on the welding fixture. Step 3: Material unloading. After welding is completed, control the welding platform to return to its original position, and then control the upper electric telescopic cylinder to move the base plate below the corresponding welding platform. The restriction on the welding fixture can then be automatically released by the release mechanism. Finally, the CCS integrated wire harness and the welding fixture can be removed.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1.

[0020] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0022] In practical use, it was found that in the existing CCS welding process, the accessories are usually placed on the welding fixture 3, and then the workers arrange the wires. During the wire arrangement process, the workers need to use wire crimping pliers to press the ends of the wire harness to ensure the stability of the subsequent welding process. However, due to the large number of welding points, the number of wire crimping pliers is also large. After the welding is completed, the workers need to pry the wire crimping pliers off the wire harness one by one. This process is time-consuming and laborious, especially when a large number of welding points need to be processed, which significantly reduces production efficiency. In order to solve the above problems, the following structure was invented.

[0023] like Figures 1-10 The CCS processing equipment shown includes a laser welding machine 1 and a welding fixture 3. The working principle of the CCS wire bundle laser welding machine 1 mainly involves several key steps such as laser generator, optical system, focal point focusing, molten pool formation, and welding control system. First, the laser generator generates a high-energy laser beam, which is then precisely adjusted and focused by the optical system to focus the laser beam onto the welding material. The high-energy laser instantly heats the material to form a molten pool. The welding control system monitors and adjusts the welding parameters in real time to ensure the stability and consistency of the welding process. A pair of automatically lateral welding platforms 2 are staggered on the inner side of the laser welding machine 1. The two staggered welding platforms 2 can achieve alternating feeding, saving welding time. The top of each welding platform 2 has a placement groove 4 for placing the welding fixture 3. The placement groove 4 is stepped to prevent the welding fixture 3 from falling out of the placement groove 4. The placement groove 4 is equipped with a positioning mechanism 36 for limiting the position of the welding fixture 3. The positioning mechanism 36 mainly includes a hydraulic telescopic cylinder, a plug rod, and an opening. The welding fixture 3 is equipped with a socket and other structures that can automatically lock the position of the welding fixture 3, ensuring stability during welding and unlocking. Top grooves 5 are provided on both sides of the top of the welding fixture 3. Several fixing frames 6 are equidistantly arranged within the top grooves 5. Vertical blocks 7 are longitudinally slidably connected to the inner sides of the fixing frames 6. Side grooves 8 are provided through the side walls of the fixing frames 6. Horizontal blocks 9 are slidably connected through the side walls of the vertical blocks 7 relative to their positions within the side grooves 8. A wire clamping head 25 for clamping the end of the wire harness is fixedly connected to the side wall of the horizontal block 9. 5 can press down the outer position of the wire harness end, and the middle is a hollow structure to avoid affecting the normal welding of the laser welding machine 1. The bottom end of the vertical block 7 is provided with a bottom groove 10. The bottom groove 10 is horizontally slidably connected to a limit rod 11. The limit rod 11 is provided with a limit mechanism for limiting the position of the horizontal block 9 and the vertical block 7. A pair of upper electric telescopic cylinders 12 are fixedly connected through the bottom end of the laser welding machine 1. The output ends of the upper electric telescopic cylinders 12 are fixedly connected to a base plate 13. The base plate 13 is provided with a release mechanism for releasing the limit mechanism.

[0024] The limiting mechanism includes an upper block 14, a groove at the top of the limiting rod 11, the upper block 14 being slidably connected to the inside of the groove, an upper right-angle block 16 with an inclined surface being fixedly connected to the top of the upper block 14, several right-angle slots 17 with inclined surfaces being equidistantly opened at the bottom of the horizontal block 9, a T-shaped rod 18 being slidably connected through the side wall of the limiting rod 11, the bottom of the side end of the T-shaped rod 18 being inclined, a through groove 19 being opened on the outer wall of the fixed frame 6 relative to the position next to the T-shaped rod 18, several lower right-angle blocks 20 with inclined surfaces being fixedly connected equidistantly on the inside of the through groove 19; An upper spring 15 is fixedly connected between the bottom end of the groove and the bottom end of the upper block 14. A pair of lower springs 21 are fixedly connected between the side wall of the T-shaped rod 18 and the side wall of the limiting rod 11. With the setting of the upper spring 15 and the lower spring 21, the upper right-angle block 16 and the T-shaped rod 18 can be quickly pushed into the corresponding limiting position. A limiting plate 22 is fixedly connected to the side wall of the horizontal block 9, which restricts the sliding position of the horizontal block 9. A pair of upper return springs 23 are fixedly connected between the outer wall of the fixed frame 6 and the limiting plate 22. A lower return spring 24 is fixedly connected between the bottom end of the side groove 8 and the outer wall of the vertical block 7. With the setting of the upper return springs 23 and the lower return springs 24, the horizontal block 9 and the vertical block 7 can be quickly pushed to reset after the release mechanism is activated and the limit is released. Several limiting springs 43 are fixedly connected between the inner side of the bottom groove 10 and the side wall of the limiting rod 11. Guide grooves are provided at both ends of the bottom groove 10. A guide plate 26 is fixedly connected to the outer wall of the limiting rod 11 relative to the inner side of the guide groove. The guide groove and guide plate 26 can guide the sliding of the limiting rod 11 in the bottom groove 10. A pressing head 27 is fixedly connected to the top of the vertical block 7. The pressing head 27 makes it easy to press the vertical block 7 and improves the convenience of the device. The release mechanism includes a drive motor 28, a pair of side plates 29 fixedly connected to the top of the base plate 13, a threaded rod 30 rotatably connected between the side plates 29, the drive motor 28 fixedly connected to the side wall of one of the side plates 29, the output end of the drive motor 28 passing through the side wall of the side plate 29 and fixedly connected to the side wall of the threaded rod 30, a sliding frame 31 slidably connected to the top of the base plate 13, and the threaded rod 30 threadedly connected to the inner side wall of the sliding frame 31, a push plate 32 slidably connected to the inner side of the sliding frame 31, three round rods 33 fixedly connected to the bottom end of the push plate 32, the bottom end of the round rods 33 passing through the bottom end of the sliding frame 31, and a number of release grooves 42 are equidistantly opened on the top of the base plate 13, and the side of the release grooves 42 away from the sliding frame 31 is inclined. Several return springs 34 are fixedly connected between the bottom end of the push plate 32 and the bottom end of the inner side of the sliding frame 31. The bottom end of the round rod 33 is set as a smooth arc surface. A notch is opened at the top of the push plate 32. An L-shaped plate 35 is fixedly connected to the side wall of the push plate 32 at the position below the notch. Since the positions of the pressure head 25 on both sides are different, the L-shaped plate 35 can be used to push the limit rods 11 on both sides to slide at the same time, so as to ensure that both sides are unlocked at the same time. When welding CCS integrated wire harnesses, the CCS wire harness accessories are first placed in the welding fixture 3. Then, the wire harness ends are placed on the welding points of the connecting pieces in sequence. At the same time, the horizontal block 9 is pushed to move on the vertical block 7, compressing the upper return spring 23. Simultaneously, the right-angle slot 17 is moved to move below the upper right-angle block 16 (initially, the upper right-angle block 16, upper block 14, and upper spring 15 are compressed by the horizontal block 9), thus releasing the pressure on the upper right-angle block 16. Subsequently, under the elastic force of the upper spring 15, the compression of the upper right-angle block 16 is released. Push the upper block 14 and the upper right-angle block 16 into the corresponding right-angle slot 17. If the pressing head 25 has not reached the pressing position at this time, the limiting plate 22 can be pushed further. At the same time, the inclined surface of the right-angle slot 17 at the bottom of the horizontal block 9 presses the inclined surface of the upper right-angle block 16, thereby pressing the upper right-angle block 16 and the upper block 14 to move downward and compressing the upper spring 15. Then, when the upper right-angle block 16 moves to the side of another right-angle slot 17, the pressing on the upper right-angle block 16 will be released. Repeat the above operation until the pressing head 25 moves above the pressing position. The pressing head 27 can be pushed to move the vertical block 7 downwards, while the horizontal block 9 slides in the side groove 8 and compresses the lower reset spring 24. At the same time, the T-shaped rod 18 moves downwards. At this time, the position of the lower right-angle block 20 is fixed, so the inclined surface of the lower right-angle block 20 will press the inclined surface of the bottom end of the T-shaped rod 18, causing the T-shaped rod 18 to slide. At the same time, the lower spring 21 is stretched. Then the T-shaped rod 18 moves to the side of another lower right-angle block 20, releasing the compression of the T-shaped rod 18. Then, under the elastic force of the lower spring 21, the side end of the T-shaped rod 18 is pulled into the side wall of another lower right-angle block 20. This is repeated until the pressing head 25 presses the end of the wire harness onto the connecting piece, while the T-shaped rod 18 is inserted under one of the lower right-angle blocks 20, restricting the upward sliding position of the T-shaped rod 18. Then, after all the wire harnesses are laid out, the welding fixture 3 can be placed in the placement groove 4 on the welding platform 2, and the position of the welding fixture 3 is restricted by the positioning mechanism 36. The welding platform 2 can be moved into the laser welding machine 1, and the laser welding machine 1 can be started to automatically weld the CCS integrated wire harness. During this process, another set of CCS integrated wire harnesses can be arranged, and the welding fixture 3 with the wire arrangement completed can be placed on another welding platform 2. After the first set of welding is completed, the positions of the two welding platforms 2 can be switched. The upper electric telescopic cylinder 12 can be started to drive the base plate 13 to move upward, so that the push plate 32 moves below the welding fixture 3. Then, the drive motor 28 is started to drive the threaded rod 30 to rotate, which in turn drives the threaded sliding frame 31 to slide on the base plate 13. At the same time, the push plate 32 and the L-shaped plate 35 are moved. Then, the push plate 32 and the L-shaped plate 35 move to the side of the limit rods 11 on both sides. Then, under the continued drive of the drive motor 28, the limit rods 11 will be pushed to slide in the bottom groove 10. At the same time, the upper right-angle block 16 will slide out from the right-angle groove 17, and the T-shaped rod 18 will move out from below the lower right-angle block 20, thereby releasing the position restriction on the horizontal block 9 and the vertical block 7. Subsequently, under the elastic force of the upper return spring 23 and the lower return spring 24, the horizontal block 9 and the vertical block 7 are pushed to reset, and at the same time, the limiting rod 11 is driven to move upward (it should be noted that at this time, the limiting rod 11 will not move out of the side wall of the push plate 32 and the L-shaped plate 35), while the limiting spring 43 is compressed. Then, the round rod 33 at the bottom of the push plate 32 moves above the release groove 42 (in the initial position, the round rod 33 is in a state of being squeezed by the bottom plate 13, and the return spring 34 is in a state of being stretched), thereby releasing the compression on the round rod 33. Then, under the elastic force of the return spring 34, the push plate 32 and the L-shaped plate 35 are pulled downward, thereby driving the push plate 32 and the L-shaped plate 35 to move downward quickly, from the limiting... As the sliding frame 31 continues to move, the round rod 33 gradually moves out from the inclined surface of the release groove 42 and onto the bottom plate 13, driving the push plate 32 and L-shaped plate 35 to move upwards. At the same time, the return spring 34 is stretched. Then, the push plate 32 and L-shaped plate 35 move below another limit rod 11. This process is repeated to automatically unlock all the wire clamps 25. Finally, the positioning mechanism 36 is controlled to release the limit on the welding fixture 3, and the CCS centralized wire harness and welding fixture 3 can be removed. (It should be noted that when the wire clamps 25 on the upper welding platform 2 need to be unlocked, the lower welding platform 2 needs to be moved away, and then the upper electric telescopic cylinder 12 is controlled to raise the bottom plate 13 to unlock them.) In summary, the above structural design not only allows workers to press the crimping heads 25 one by one onto the wire bundle head during the wiring process, but also enables the rapid release of all crimping heads 25 after welding, eliminating the need for workers to pry them apart one by one, thus greatly improving the processing efficiency of the device.

[0025] Based on the above embodiments, it was found during use that if the fixing frame 6 is fixedly set on the welding fixture 3, it is not possible to flexibly disassemble and assemble according to the design of the CCS integrated wire harness, which is quite limiting. In order to solve the above problems, the above structure has been further improved.

[0026] The welding fixture 3 has a central groove 37 on both the front and rear sides, which is connected to the top groove 5. The outer wall of the fixing frame 6 is connected to a bolt 38. The inner side of the top groove 5 has several threaded grooves 39 at equal intervals (it should be noted that the spacing between the threaded grooves 39 is fixed, and the spacing between each threaded groove 39 and the release groove 42 is also fixed. Therefore, the number of threaded grooves 39 is the same as the number of release grooves 42, thus ensuring that the push plate 32 and the L-shaped plate 35 can move out normally from the corresponding limit rod 11). The side ends of the bolts 38 are threaded into the threaded grooves 39. The side wall of the vertical block 7 has a straight groove 40 relative to the position next to the bolts 38. The straight groove 40 is used to prevent the bolts 38 from obstructing the vertical block 7 from sliding up and down. The bolts 38 are inserted into the straight groove 40. The bottom ends of the top groove 5 are fixedly connected to the limiting strips 41 for limiting the position of the fixing frame 6. When it is necessary to disassemble and assemble the fixing frame 6 and the wire clamp 25, first unscrew the bolt 38 from the corresponding threaded groove 39 from the central groove 37 and remove the bolt 38 to release the position restriction of the fixing frame 6. Then pull out the fixing frame 6, the vertical block 7 and the horizontal block 9 to remove the wire clamp 25, reducing the overall weight of the welding fixture 3 and making it easier to move the welding fixture 3 when there are few welding points. When installation is required, repeat the above operation in reverse to install. It can be flexibly adjusted according to the needs of the welding points.

[0027] In summary, the above structural design allows for flexible installation and removal of the crimp heads 25 at corresponding positions when the number of soldering points increases or decreases, based on the design of the CCS integrated wiring harness. This greatly improves the flexibility of the device, meets user needs, and does not affect the automatic unlocking of all crimp heads 25.

[0028] A CCS processing method includes the following steps: Step 1: Wiring. First, place the accessories in the welding fixture 3 and arrange the wire harnesses in order. At the same time, push the horizontal block 9 and press the vertical block 7 so that the wire pressing head 25 squeezes the wire harnesses onto the connecting piece. Step 2: Loading the material. Then, place the welding fixture 3 with the wires arranged in the placement groove 4, and restrict the position of the welding fixture 3 by the positioning mechanism 36. Then, start the equipment to automatically laser weld the wires on the welding fixture 3. Step 3: Material unloading. After welding is completed, control the welding platform 2 to return to its original position, and then control the upper electric telescopic cylinder 12 to start moving the base plate 13 below the corresponding welding platform 2. The restriction on the welding fixture 3 can be automatically released by the release mechanism, and then the CCS integrated wire harness and welding fixture 3 can be taken out.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of the present invention.

[0030] Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of the present invention. Various changes and modifications can be made to the present invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
