Description

Technical Field

[0001] This invention relates to the field of electronic product component processing equipment technology, and more specifically to a copper sheet bending mechanism. Background Technology

[0002] Copper busbars are core components for high-voltage, high-current transmission in the three-electric system of new energy vehicles. Leveraging their comprehensive advantages in conductivity, heat dissipation, and safety, they are poised for strong medium- to long-term growth driven by the four key trends of electrification, 800V high-voltage platforms, fast charging, and battery integration, with a continuously expanding market space. Bent copper busbars (formed busbars) are manufactured by CNC bending, stamping, milling, and surface tin / silver plating of T2 copper / copper-chromium-zirconium copper busbars to create multi-angle, irregularly shaped bends, adapting them to the confined spaces within battery packs and electronic control systems.

[0003] Unlike straight copper busbars: Due to the limited space in the internal pipelines and housings of the three electric components in the vehicle, copper busbars must avoid structural components by using 90°, 45°, Z-shaped, U-shaped, and stepped bends. This type of copper busbar is the most widely used in new energy vehicles.

[0004] However, existing copper busbar bending is generally done manually, which is inefficient, labor-intensive, and has limited precision. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a copper sheet bending mechanism that can automatically clamp and bend copper busbars, and is suitable for bending both vertical and horizontal copper busbars.

[0006] The solution of the present invention to the aforementioned technical problem is:

[0007] A copper sheet bending mechanism includes a main housing, a transverse moving mechanism fixed in the middle of the top surface of the top plate of the main housing, a clamping device fixed on the transverse moving block of the transverse moving mechanism, and the rear of the copper busbar clamped on the clamping device.

[0008] A support column is fixed on the top plate of the main housing in front of the lateral moving mechanism. An outer sleeve is movably connected to the outer wall of the support column. A transmission gear is fixed at the lower part of the outer wall. A rotary servo motor is fixed on the bottom surface of the top plate of the main housing on one side of the support column. The top end of the output shaft of the rotary servo motor extends out of the through hole of the top plate of the main housing and is fixed with a drive gear. The drive gear meshes with the transmission gear.

[0009] An upper outer sleeve is movably connected to the upper outer wall of the support column, and a middle annular sleeve is fixed to its outer wall. Two limiting installation blocks are fixed to the top surface of the outer side of the middle annular sleeve, and a limiting pressure column is fixed to the top surface of the limiting installation blocks.

[0010] The top of the support column is fixed with a top limiting circular block. The top surface of the top limiting circular block is formed with a transverse limiting through groove that extends downward and protrudes forward and backward from the side wall of the top limiting circular block. The transverse limiting through groove corresponds to the clamping device.

[0011] The lateral movement mechanism includes a bottom plate with end plates fixed at both its left and right ends. A lateral screw extending forward and backward is movably connected to the two end plates via bearings. The rear end of the lateral screw extends out of the rear end plate and is fixed with a first synchronous pulley. A through groove is formed on the top plate of the main housing below the first transmission gear.

[0012] The bottom of the rear end plate is fixed with a downwardly extending connecting plate. The bottom of the connecting plate extends out of the bottom end of the through groove. A moving servo motor is fixed on it. The output shaft of the moving servo motor extends out of the corresponding connecting plate and is fixed with a first drive synchronous pulley. The synchronous belt is tensioned on the first drive synchronous pulley and the first synchronous pulley and cooperates with them. The synchronous belt is inserted into the through groove.

[0013] A transverse moving block is screwed onto the transverse screw. Guide portions are formed on the left and right sides of the transverse moving block. The top arc-shaped surfaces of the side extension portions formed on the left and right sides of the top surface of the bottom plate are against the transverse moving block. An upper connecting block is fixed to the top surface of the transverse moving block. An upper through groove is formed in the middle of the top surface of the upper connecting block. An upper transverse plate is fixed between the tops of the two end plates. It is inserted into the upper through groove and cooperates with it. An upper horizontal plate is fixed to the top surface of the upper connecting block.

[0014] The clamping device is a double-shaft cylinder, the bottom of which is fixed on the top surface of the upper horizontal plate. The ends of the push rods on both sides are fixed with clamping plates. Side clamping blocks are fixed on the upper opposite walls of the two clamping plates. The copper busbar to be processed is clamped on the two side clamping blocks. The front part of the copper busbar is inserted into the transverse limiting through groove, and its left and right sides are in close contact with the corresponding inner side walls of the transverse limiting through groove. The front end of the copper busbar extends out of the front part of the transverse limiting through groove.

[0015] An intermediate outer sleeve is fixed between the intermediate annular sleeve and the transmission gear. The intermediate outer sleeve is fitted over the outside of the support column. A recessed hole is formed on the outer wall of the middle part of the intermediate outer sleeve. A connecting plate is fixed on the top surface of the top plate of the main housing on one side of the support column. A proximity switch is fixed on the plate. The sensing end of the proximity switch corresponds to the corresponding recessed hole.

[0016] The outstanding effects of this invention are:

[0017] Compared with existing technologies, it can automatically clamp and bend copper busbars, and it is suitable for bending both vertical and horizontal copper busbars. Attached Figure Description

[0028] An upper outer sleeve is movably connected to the upper outer wall of the support column 11, and a middle annular sleeve 15 is fixed on its outer wall. Two limiting mounting blocks 16 are fixed on the top surface of the outer side of the middle annular sleeve 15, and a limiting pressing column 17 is fixed on the top surface of the limiting mounting block 16.

[0029] The top of the support column 11 is fixed with a top limiting circular block 18. The top surface of the top limiting circular block 18 has a transverse limiting through groove 181 that extends downward and protrudes forward and backward from the side wall of the top limiting circular block 18. The transverse limiting through groove 181 corresponds to the clamping device 30.

[0030] Furthermore, the lateral movement mechanism 20 includes a bottom plate with end plates fixed at both its left and right ends. A lateral screw 22 extending forward and backward is movably connected to the two end plates via bearings. The rear end of the lateral screw 22 extends out of the rear end plate and is fixed with a first synchronous pulley 23. A through groove is formed on the top plate of the main housing 10 below the first synchronous pulley 23.

[0031] The bottom of the rear end plate is fixed with a downwardly extending connecting plate. The bottom of the connecting plate extends out of the bottom end of the through groove. A moving servo motor 24 is fixed on it. The output shaft of the moving servo motor 24 extends out of the corresponding connecting plate and is fixed with a first drive synchronous pulley 25. The synchronous belt 26 is tensioned on the first drive synchronous pulley 23 and the first synchronous pulley 25 and cooperates with them. The synchronous belt 26 is inserted into the through groove.

[0032] A transverse moving block 21 is screwed onto the transverse screw 22. Guide portions are formed on the left and right sides of the transverse moving block 21. The top arc-shaped surfaces of the side extension portions formed on the left and right sides of the top surface of the bottom plate are against the guide portions. An upper connecting block is fixed to the top surface of the transverse moving block 21. An upper through groove is formed in the middle of the top surface of the upper connecting block. An upper transverse plate is fixed between the tops of the two end plates. It is inserted into the upper through groove and cooperates with it. An upper horizontal plate is fixed to the top surface of the upper connecting block.

[0033] Furthermore, the clamping device 30 is a double-output shaft cylinder, the bottom of which is fixed to the top surface of the upper horizontal plate. The ends of the push rods on both sides are fixed with clamping plates 31. Side clamping blocks 32 are fixed on the upper opposite walls of the two clamping plates 31. The copper busbar 100 to be processed is clamped on the two side clamping blocks 32. The front part of the copper busbar 100 is inserted into the transverse limiting groove 181, and its left and right sides are closely attached to the corresponding inner side walls of the transverse limiting groove 181. The front end of the copper busbar 100 extends out of the front part of the transverse limiting groove 181.

[0034] Furthermore, an intermediate outer sleeve 19 is fixed between the intermediate annular sleeve 15 and the transmission gear 12. The intermediate outer sleeve 19 is fitted over the support column 11. A recessed hole is formed on the outer wall of the middle part of the intermediate outer sleeve 19. A connecting plate is fixed on the top surface of the top plate of the main box 10 on one side of the support column 11, and a proximity switch 2 is fixed on it. The sensing end of the proximity switch 2 corresponds to the corresponding recessed hole.

[0035] Furthermore, an outer protective shell 3 is fixed at the front of the top plate of the main housing 10, and the drive gear 14 and the transmission gear 12 are located in the outer protective shell 3. The upper parts of the middle annular sleeve 15 and the support column 11 extend out of the top of the middle through hole of the outer protective shell 3.

[0036] Furthermore, multiple lower vertical support columns are fixed to the bottom surface of the top plate of the main housing 10 on one side of the support column 11. The clamping cylinder 40 is fixed to the bottom end of all the vertical support columns. The top end of the push rod of the clamping cylinder 40 is fixed with a vertical lifting rod 41. The middle part of the vertical lifting rod 41 is inserted into the through hole formed on the top plate of the main housing 10. The top surface of the top plate of the main housing 10 is fixed with an upper guide sleeve 42. The vertical lifting rod 41 is inserted into the upper guide sleeve 42, and its outer side wall is close to the inner side wall of the upper guide sleeve 42. The top end of the vertical lifting rod 41 extends out of the top end of the upper guide sleeve 42 and is fixed with an upper clamping arm 43. The bottom surface of the upper clamping arm 43 is movably connected with an upper pressure block 44. The bottom surface of the upper pressure block 44 is formed with an inner concave hole. The upper part of the top limiting circular block 18 is inserted into the inner concave hole. The front top surface of the copper busbar 100 is close to or close to the top surface of the inner concave hole.

[0037] Furthermore, a lifting limit post 6 is fixed on the middle side wall of the vertical lifting rod 41, and a vertical guide plate 19 is fixed on the bottom surface of the top plate of the main box 10. A vertical guide groove 191 is formed in the middle of the vertical guide plate 19, and the lifting limit post 6 is inserted into the vertical guide groove 191 and cooperates with it.

[0038] Furthermore, the upper part of the opposite wall surface of the two side clamping blocks 32 is formed with an upper groove, the elastic clamping block is embedded in the groove and fixed in the groove, and the vertical copper busbar 100 is clamped between the opposite wall surface of the two side clamping blocks 32 and the two elastic clamping blocks. When clamping the horizontally arranged copper busbar 100, the bottom surface of the left and right parts of the copper busbar 100 presses against the top surface of the groove of the side clamping block 32 and is embedded in the inner side of the lower part of the two elastic clamping blocks, so that the inner side of the lower part of the two elastic clamping blocks is compressed inward to form a lower slot, thereby clamping the left and right parts of the copper busbar 100.

[0039] In this embodiment, all cylinders and hydraulic cylinders are connected to the corresponding pneumatic or hydraulic systems via air pipes and oil pipes, respectively. They and all electrical components are electrically connected to the control host via electrical connection lines, and the operation is controlled by the control host.

[0040] In this embodiment, it can be used to process the bending of vertical copper busbars 100 and horizontal copper busbars 100.

[0041] When installing a vertical copper busbar 100, such as Figures 1 to 5As shown, the middle part is placed on the top surface of the double-output shaft cylinder and operated by the double-output shaft cylinder, so that the copper busbar 100 is clamped on the two side clamping blocks 32. At the same time, the front part of the copper busbar 100 is inserted into the transverse limiting groove 181, and its left and right sides are in close contact with the corresponding inner sidewalls of the transverse limiting groove 181. The front end of the copper busbar 100 extends out of the front part of the transverse limiting groove 181. Then, by retracting the push rod of the pressing cylinder 40, the upper pressure block 44 is lowered, and the upper part of the top limiting circular block 18 is inserted into the concave hole. The top surface of the front part of the copper busbar 100 is close to or in close contact with the top surface of the concave hole, so that the copper busbar... The copper busbar 100 is clamped and fixed. Then, the servo motor 13 is operated so that the two limit pressing posts 17 rotate with the middle annular sleeve 15. The limit pressing posts 17 at the front end press against one side wall of the front end of the copper busbar 100 and bend the front end of the copper busbar 100 to the other side as the middle annular sleeve 15 rotates. This continues until the sensing end of the proximity switch 2 is facing the concave hole. At this time, the sensing end of the proximity switch 2 does not sense the outer wall of the middle outer sleeve 19, indicating that it has rotated to the correct position. After the control host receives the sensing signal, it controls the servo motor 13 to stop running and completes the bending.

[0042] Once all components are back in place, the bent copper busbar 100 can be removed, and a new copper busbar 100 can be installed for subsequent processing.

[0043] like Figures 6 to 7 As shown, the top limiting circular block 18 needs to be replaced with a top limiting circular block 18 having a transverse limiting groove 181 corresponding to the width of the horizontal copper busbar 100. Similarly, the upper pressure block 44 also needs to be replaced, with its copper busbar 100 clamped in the two side clamping blocks 32. At the same time, the corresponding edge of the copper busbar 100 is in the lower slot formed on the lower part of the opposite wall of the side clamping block 32, completing the clamping and fixing. Then, as described above, it can be bent, which is very convenient. The top surface of the top limiting circular block 18 has a front groove formed, which communicates with the front end of the transverse limiting groove 181. The left and right sides of the front end of the transverse limiting groove 181 are arc-shaped walls to ensure that the horizontal copper busbar 100 can be bent along the arc-shaped walls when bent.

[0044] The extension and retraction distance of the push rod of the clamping cylinder 40 is achieved by inserting the lifting limit pin 6 into the vertical guide groove 191, and by pressing the lifting limit pin 6 against the bottom or top of the vertical guide groove 191.

[0045] The processing effect in this embodiment is good.

[0046] Finally, the above embodiments are only used to illustrate the present invention and are not intended to limit the present invention. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also fall within the scope of the present invention, and the patent protection scope of the present invention should be defined by the claims.
