Description

Technical Field

[0001] This invention relates to the technical field of vehicle-mounted energy meters, and more particularly to an automatic crimping device and method for energy meter terminals. Background Technology

[0002] As the core equipment for detecting automotive power data, the vehicle-mounted energy meter mainly consists of a terminal insulating base, wiring terminals, a housing, and a built-in detector. During the manufacturing process, the wiring terminals need to be pressed into a shape that fits the insulating base using a crimping device and then firmly assembled to ensure the reliability of subsequent installation and connection. Existing crimping devices employ various methods to achieve automatic crimping of terminals. For example, the automatic flattening device for quartz crystal terminals disclosed in CN108134299A includes a base box. A bracket is fixedly connected to the left side of the top of the base box. A horizontal plate is fixedly connected to the top of the bracket. An electric telescopic rod is fixedly connected to the bottom of the horizontal plate. A pressure plate is fixedly connected to the bottom of the electric telescopic rod. A support plate is fixedly connected to the back of the inner wall of the base box.

[0003] Existing crimping equipment mostly uses a single crimping mechanism and lacks automated loading and unloading functions. During loading, it is easy to produce large errors, resulting in crimping misalignment, which affects product consistency. In addition, metal debris generated during the crimping process can easily remain on the crimping surface or in the insulating seat. Over time, this accumulation can cause problems such as poor terminal contact and reduced insulation performance.

[0004] For example, the aforementioned prior art, although the device uses a flattening mechanism to clamp and flatten the terminals, it is only suitable for processing terminals of a single material and shape. It lacks automated coordination capabilities and cannot simultaneously realize the automated continuous crimping operation of multiple terminals on the terminal insulation seat. Furthermore, it cannot absorb and remove the metal debris generated during crimping, which can easily affect the crimping effect over a long period of time. It has disadvantages such as low production efficiency and low product qualification rate. Therefore, it is urgent to design an automatic crimping device and method for electricity meter terminals to solve the above problems. Summary of the Invention

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0025] Example 1: Refer to Figures 1-4 An automatic crimping device for electricity meter terminals includes multiple terminal insulating seats 10 disposed on a crimping table 1, and each terminal insulating seat 10 is provided with multiple terminals 17 to be crimped. The crimping device crimps the terminals 17 into a set shape to facilitate subsequent assembly.

[0026] This crimping device also includes: The feeding unit is set on the crimping table 1. The feeding unit is used to realize the automatic conveying, feeding, positioning and unloading of the terminal insulation seat 10 to be processed, and to complete the orderly switching of multiple workstations. At the same time, it realizes the stable positioning of the terminal insulation seat 10, which can effectively avoid feeding errors, improve the continuity of the crimping operation of the terminal insulation seat 10, and ensure the stability of the position of the terminal insulation seat 10 during processing, thus providing a guarantee for subsequent accurate crimping.

[0027] The crimping unit is located inside the crimping table 1. The crimping unit can accurately complete the crimping deformation of multiple terminals 17 on the terminal insulating base 10, and can flexibly adjust the crimping depth and shape according to the crimping requirements. It has the advantages of high crimping accuracy and good consistency, and the terminals are firmly assembled. It can adapt to the processing requirements of multiple specifications, effectively avoid debris from affecting the crimping quality, and significantly improve the pass rate of crimping of terminals 17.

[0028] The side of the crimping station 1 is equipped with an intelligent control host 2. The intelligent control host 2 is used to control the opening and closing and operation status of the feeding unit and the crimping unit, so as to realize the automated crimping of multiple terminals 17 on the terminal insulation seat 10. No manual intervention is required during the crimping process, and the crimping efficiency and crimping accuracy are both higher.

[0029] Example 2: Refer to Figures 2-9 The difference between this embodiment and embodiment one is that the feeding unit includes a placement component, an adjustment component and a conveying component. The placement component is provided with multiple placement boxes 9 for placing terminal insulating seats 10. The adjustment component is used to adjust the position of multiple placement boxes 9 to realize the sequential pressing of multiple terminal insulating seats 10. The conveying component is used to realize the automatic loading and unloading of terminal insulating seats 10.

[0030] The adjustment assembly includes an internal cavity 7 opened in the pressing table 1. A servo motor 8 is fixedly installed in the internal cavity 7, and a drive roller 13 for outputting power is rotatably installed between the drive end of the servo motor 8 and the internal cavity 7. A one-way bearing 18 is provided on the drive roller 13, and the one-way bearing 18 cooperates with the forward rotation of the drive roller 13. A support plate 6 is fixedly installed on the one-way bearing 18. When crimping the terminals 17 on the terminal insulating base 10, the servo motor 8 is started to drive the drive roller 13 to rotate in the forward direction. When the drive roller 13 rotates in the forward direction, it will drive the support plate 6 to rotate as a whole.

[0031] The placement assembly includes multiple placement boxes 9 fixedly installed on the support plate 6. The placement boxes 9 are used to place the positioning terminal insulation seats 10. The conveying assembly includes a feeding conveyor 3 set on the crimping table 1. The crimping table 1 has a discharge opening 4, and a discharge conveyor 5 is set on the discharge opening 4. The feeding conveyor 3 is used to convey the terminal insulation seats 10 to be crimped, and the discharge conveyor 5 is used to convey the crimped terminal insulation seats 10. Both the feeding conveyor 3 and the discharge conveyor 5 are equipped with a picking robot for picking up the terminal insulation seats 10. The feeding conveyor 3 and the unloading conveyor 5 are commonly used automated conveyor belts in the prior art, used to transport the terminal insulating seats 10 on them. This part is prior art and will not be described in detail here.

[0032] During the crimping process, the picking robot on the feeding conveyor 3 will start and sequentially grab the terminal insulating base 10 conveyed on it, and place them sequentially on the placement box 9 on the support plate 6, completing the automated feeding of the terminal insulating base 10. After the terminal insulating base 10 on the placement box 9 is crimped, it will continue to rotate and be conveyed on the placement box 9. When the placement box 9 moves to the unloading opening 4, the picking robot on the unloading conveyor 5 will start, grab the terminal insulating base 10 on the placement box 9, and place it on the unloading conveyor 5, completing the automated unloading and conveying. The unloaded placement box 9 will continue to rotate onto the feeding conveyor 3, where it can be automatically loaded again. The above steps are repeated to complete the automated loading, transfer, crimping, transfer, automated unloading and reloading process of the terminal insulating base 10, thereby achieving efficient and uninterrupted crimping of the terminal insulating base 10.

[0033] In a further embodiment, each placement box 9 is fixedly mounted with a clamping positioning plate 19 for clamping the positioning terminal insulating seat 10 by a plurality of compression spring rods 20, and each clamping positioning plate 19 is fixedly mounted with a push sliding rod 21 for assisting the terminal insulating seat 10 to be pressed down. When the robotic arm places the terminal insulation seat 10, the bottom of the terminal insulation seat 10 will first contact the two push sliding rods 21 on the two clamping positioning plates 19. As the terminal insulation seat 10 moves down, it will gradually squeeze the two push sliding rods 21 to move to both sides. When the push sliding rods 21 move, they will drive the clamping positioning plates 19 to move synchronously. When the clamping positioning plates 19 move, they will squeeze the two compression spring rods 20 to compress them, thereby increasing the distance between the two clamping positioning plates 19 and enabling the terminal insulation seat 10 to move down between the two terminal insulation seats 10 until the terminal insulation seat 10 moves down to the bottom of the placement box 9. At this point, the robotic arm will separate from the terminal insulating base 10 and return to its original position. The two clamping positioning plates 19 will apply lateral pressure to the terminal insulating base 10 under the action of the compression spring rod 20. The two clamping positioning plates 19 on both sides can firmly clamp and compress the terminal insulating base 10, maintain its placement stability in the placement box 9, and ensure that it will not shake during crimping.

[0034] Example 3: Refer to Figures 2-5 as well as Figures 10-15 The difference between this embodiment and embodiment two is that the crimping unit includes a transmission assembly, a lifting assembly and a crimping assembly. The crimping assembly is provided with a crimping seat 29, and the crimping seat 29 is provided with a plurality of crimping grooves 34 for crimping deformation of the terminal 17. The lifting assembly is provided with a lifting seat 23 for adjusting the crimping depth, and the lifting seat 23 is provided with a plurality of crimping parts 35 for pressing the terminal 17.

[0035] The terminal insulating base 10 inside the box 9 rotates with the rotation of the support plate 6. When the terminal insulating base 10 rotates to the upper part of the crimping base 29, the servo motor 8 will stop driving the drive roller 13 to rotate in the forward direction. At this time, the support plate 6 and the terminal insulating base 10 on it stop rotating. At the same time, the servo motor 8 will drive the drive roller 13 to rotate in the reverse direction. When the drive roller 13 rotates in the reverse direction, the support plate 6 and the multiple terminal insulating bases 10 on it will not rotate.

[0036] The transmission assembly includes a linkage rod 11 rotatably mounted between the built-in cavity 7 and the pressing table 1, a one-way bearing 28 is provided on the drive roller 13, and the one-way bearing 28 cooperates with the reverse rotation of the linkage rod 11. A transmission belt 12 is sleeved between the linkage rod 11 and the one-way bearing 28. When the drive roller 13 rotates in the reverse direction, it will drive the one-way bearing 28 on it to rotate (at this time, the one-way bearing 18 does not rotate). When the one-way bearing 28 rotates, it will drive the linkage rod 11 to rotate as a whole under the action of the transmission belt 12.

[0037] In a further embodiment, the lifting assembly includes a reciprocating lead screw 14 fixedly mounted on the linkage rod 11, a ball nut disc 15 slidably mounted in the pressing table 1 via two limiting slide rods 16, and the ball nut disc 15 cooperates with the reciprocating lead screw 14, and the lifting seat 23 is fixedly mounted on the side of the ball nut disc 15. When the linkage rod 11 rotates, it will drive the reciprocating screw 14 on it to rotate. When the reciprocating screw 14 rotates, it will drive the ball nut disc 15 that cooperates with it, so that the ball nut disc 15 moves up and down on the outside of the reciprocating screw 14. When the ball nut disc 15 moves up and down, it will drive the lifting seat 23 to move up and down.

[0038] The cooperation between the reciprocating lead screw 14 and the ball nut disc 15 is existing technology. The specific principle is as follows: the reciprocating lead screw 14 is a form of three-dimensional cam pair. Its specific structure consists of two threaded grooves with the same pitch and opposite directions of rotation. The two ends of the lead screw are connected by a transition curve. By rotating the lead screw, the side of the helical groove pushes the balls located in the helical groove of the ball nut disc 15 to make axial reciprocating motion. The reciprocating motion of the balls will drive the ball nut disc 15 to move back and forth. That is, when the reciprocating lead screw 14 rotates in one direction, it can drive the ball nut disc 15 to make it move back and forth linearly on the reciprocating lead screw 14.

[0039] In a further embodiment, the crimping assembly includes a locking seat 30 fixedly installed in the crimping table 1, and the locking seat 30 is locked onto the crimping table 29. An extension table 31 is fixedly installed on the lifting table 23, and a positioning pressure plate 32 is fixedly installed on the extension table 31 through two positioning spring rods 36. The positioning pressure plate 32 cooperates with the terminal insulating seat 10. When the lifting seat 23 moves down, it will drive the extension platform 31 to move down. When the extension platform 31 moves down, it will drive the two positioning spring rods 36 and the positioning pressure plate 32 to move down synchronously until the positioning pressure plate 32 moves to press against the upper part of the terminal insulation seat 10 on the placement box 9. At this time, when the lifting seat 23 continues to drive the extension platform 31 to move down, it will press against the two positioning spring rods 36 and apply pressure to the positioning pressure plate 32 and the terminal insulation seat 10, so that the terminal insulation seat 10 can be firmly pressed into the placement box 9, further improving the crimping stability of the terminal insulation seat 10.

[0040] A connecting frame 33 is fixedly installed on the lifting seat 23, and multiple crimping parts 35 are fixedly installed on the lower part of the connecting frame 33. When the terminal insulating seat 10 is pressed and positioned, the lifting seat 23 moves down and drives the multiple crimping parts 35 to move down through the connecting frame 33. When the crimping parts 35 move down, they will press the multiple terminals 17 on the terminal insulating seat 10 and press the terminals 17 into the multiple corresponding crimping grooves 34 in the crimping seat 29. After the terminals 17 enter the crimping grooves 34, they will deform accordingly according to the shape of the crimping grooves 34 until the crimping of the terminals 17 is completed.

[0041] After the terminal 17 is crimped, the ball nut disc 15 will drive the lifting seat 23 and its upper connecting structure to move upward and reset, so that it is separated from the terminal 17. After the terminal 17 is crimped, the connection between the terminal 17 and the terminal insulating seat 10 will automatically spring back, so that the terminal 17 springs back to a straight state, realizing its automatic separation from the crimping seat 29.

[0042] The crimping seat 29 is snapped into the snap-fit ​​seat 30. Different crimping seats 29 can be replaced according to actual crimping requirements. The snap-fit ​​seat 30 has a lifting function, which can adjust the height of the crimping seat 29 on it, so as to adjust different crimping depths according to the crimping shape.

[0043] An auxiliary mechanism is provided on the pressing table 1. The auxiliary mechanism includes a cleaning cylinder 22 fixedly installed inside the pressing table 1, and a one-way bearing 18 is rotatably connected to the cleaning cylinder 22. A screening disc 26 for filtering debris is fixedly installed inside the cleaning cylinder 22. A fan impeller 27 for generating negative pressure suction is fixedly installed on the one-way bearing 18. The fan impeller 27 is located below the screening disc 26 inside the cleaning cylinder 22. An adsorption seat 24 is fixedly installed on the pressing table 1. The adsorption seat 24 is located on the side of the pressing seat 29. An adsorption tube 25 for adsorbing debris is fixedly connected between the adsorption seat 24 and the cleaning cylinder 22. After the pressing is completed, the servo motor 8 drives the drive roller 13 to rotate in the forward direction, which in turn drives the one-way bearing 18 to rotate in the forward direction, thereby driving the support plate 6 to move, and driving the multiple placement boxes 9 on it to rotate synchronously. This causes the placement box 9 that has been pressed to rotate and leave the pressing area, while the next placement box 9 to be pressed moves into the pressing area for pressing again.

[0044] As the one-way bearing 18 rotates, it will drive the impeller 27 to rotate. When the impeller 27 rotates, it will generate negative pressure suction force, which will act on the adsorption tube 25 and the adsorption seat 24. The metal debris generated during the pressing on the pressing seat 29 can be adsorbed through the adsorption seat 24, and the metal debris will enter the cleaning cylinder 22 through the adsorption seat 24 and the adsorption tube 25. The cleaning cylinder 22 is equipped with a chip discharge pipe for discharging debris and an exhaust pipe. Metal debris will be screened by the screening disc 26 and accumulated on the screening disc 26, and then discharged through the chip discharge pipe. Air will pass through the screening disc 26 and then be discharged through the exhaust pipe, thereby ensuring the air balance inside the cleaning cylinder 22.

[0045] An acceleration motor is installed inside the cleaning cylinder 22, and a wind-generating blade is installed on the drive end of the acceleration motor. When the acceleration motor starts, it drives the wind-generating blade to rotate, which will synchronously generate airflow inside the cleaning cylinder 22. This airflow works in conjunction with the impeller 27 to improve the overall strength of the airflow, thereby improving the efficiency of debris adsorption.

[0046] The working principle of this crimping device is as follows: During the crimping process, the robotic arm on the feeding conveyor 3 will start and sequentially grab the terminal insulating bases 10 conveyed on it, and place them sequentially on the placement box 9 on the support plate 6, thus completing the automated feeding of the terminal insulating bases 10. When the robotic arm places the terminal insulation seat 10, the bottom of the terminal insulation seat 10 will first contact the two push sliding rods 21 on the two clamping positioning plates 19. As the terminal insulation seat 10 moves down, it will gradually squeeze the two push sliding rods 21 to move to both sides. When the push sliding rods 21 move, they will drive the clamping positioning plates 19 to move synchronously until the terminal insulation seat 10 moves down to the bottom of the placement box 9. The robotic arm will then separate from the terminal insulation seat 10. The two clamping positioning plates 19 will apply lateral pressure to the terminal insulation seat 10 under the action of the compression spring rod 20. Thus, the terminal insulation seat 10 can be firmly clamped and squeezed by the cooperation of the two clamping positioning plates 19 on both sides.

[0047] After the terminal insulating seat 10 is placed, it will rotate to the upper part of the crimping seat 29 under the action of the support plate 6. At this time, the servo motor 8 will drive the drive roller 13 to rotate in the opposite direction. When the drive roller 13 rotates in the opposite direction, it will drive the one-way bearing 28 on it to rotate. Then, under the action of the ball nut plate 15, it will drive the lifting seat 23 to move down. When the lifting seat 23 moves down, it will drive the extension table 31 to move down, and the positioning plate 32 will perform secondary pressing and positioning on the terminal insulating seat 10. The downward movement of the lifting seat 23 will cause multiple crimping parts 35 to move downward through the connecting frame 33. When the crimping parts 35 move downward, they will squeeze multiple terminals 17 on the terminal insulating seat 10 and press the terminals 17 into multiple corresponding crimping grooves 34 in the crimping seat 29. After the terminals 17 enter the crimping grooves 34, they will deform accordingly according to the shape of the crimping grooves 34 until the crimping of the terminals 17 is completed.

[0048] After the terminal 17 is crimped, the ball nut disc 15 will drive the lifting seat 23 and its upper connection structure to move up and reset, so that it is separated from the terminal 17. After the terminal 17 is crimped, the connection between the terminal 17 and the terminal insulation seat 10 will automatically spring back, so that the terminal 17 springs back to a straight state, realizing its automatic separation from the crimping seat 29. After the terminal insulating base 10 on the placement box 9 is crimped, it will continue to rotate and be conveyed on the placement box 9. When the placement box 9 moves to the unloading opening 4, the picking robot on the unloading conveyor 5 will start, grab the terminal insulating base 10 on the placement box 9 and put it on the unloading conveyor 5 to complete the automated unloading and conveying.

[0049] This invention also provides an automatic crimping method for electricity meter terminals, used in the aforementioned automatic crimping device for electricity meter terminals, comprising the following steps: S1.
