Description

Technical Field

[0001] The present invention relates to the technical field of production of junction box components, and specifically to a wire clamp pressing device. Background Art

[0002] With the application of automated equipment in people's daily production and life, to achieve the functional application of connecting various electrical equipment, wiring connections need to be made for each electrical equipment. The wiring of electrical equipment is divided into two categories, one is the control wire, and the other is the power supply wire. Among them, the control wire requires the use of a unique control connector, and the wiring of the power supply wire mainly relies on terminals and junction boxes for line connection.

[0003] During the application of terminals and junction boxes, the wire clamp is the main structure for achieving wiring. Sometimes the wire clamp is also used independently. At present, the production and forming of wire clamps mainly adopt the stamping production process. However, during the stamping operation of the current stamping forming equipment, it is necessary to manually or automatically mechanically convey the cable and the wire clamp to the pressing station respectively.

[0004] In the current conveying methods of cables and wire clamps, most are manual operations. However, such operations are relatively inefficient, and due to the rigidity of the inner core of the cable during operation, the problem of the head end of the cable being skewed and unable to be properly aligned with the wire clamp easily occurs, resulting in the terminal sleeve being unable to completely wrap the cable during pressing. Therefore, at present, a structure for improving the pressing efficiency by an automatic feeding method has emerged.

[0005] However, during the current automatic pressing process of wire clamps, the cable is clamped by a robotic arm and placed at the pressing station. However, the setting of the robotic arm not only increases the difficulty of control work, but also has high requirements for the motion control accuracy of the robotic arm. Furthermore, the rotation and loading / unloading of the robotic arm increase the workload of the operation, resulting in a decrease in work efficiency.

[0006] Moreover, the current wire clamp pressing equipment often can only adopt a split structure and is controlled by a cylinder for pressing. Therefore, it is necessary to calibrate the feeding frequencies of the cable and the wire clamp, which increases the control difficulty. In addition, the automatic pressing equipment needs to strip the head end of the cable. After the cable is stripped, sometimes some lines of the inner core of the cable will be skewed, resulting in the terminal sleeve being unable to completely wrap all the cables during pressing, causing power loss in the power transmission of the cable. In view of this, in-depth research on the above problems has led to the generation of this case. Summary of the Invention

[0019] A using method of a wire clamp pressing device includes the following steps: wire feeding, wire clamp feeding, wire stripping, wire arranging, wire clamp terminal pressing and blanking. Wire feeding: The feeding component places the wire to be processed on the fixture at the feeding station of the multi-station disk, and a certain length is reserved at the end of the wire. The specific wire length is adjusted according to the wire stripping requirements. Wire clamp feeding: The wire clamps arranged in a chain are placed on the conveying structure. The conveying structure linearly conveys the wire clamps to one side of the pressing station of the multi-station disk, and the chain between the wire clamps will be cut when the pressing is completed. Wire stripping: When the disk rotates to the wire stripping station and the photoelectric sensor detects the position, the wire stripper acts. The wire stripper precisely strips the end of the wire, and the stripping length is adjustable to expose the internal conductor. After the wire stripping is completed, the disk continues to rotate to the next station. Wire arranging: The wire at the wire arranging station enters the wire arranging station. The wire arranger arranges the stripped conductors to ensure that all copper wires are arranged neatly without loose wires or bending. After wire arranging, the ends of the conductors are kept flush for subsequent terminal pressing. Wire clamp terminal pressing: When the disk rotates to the pressing station, at the same time, the conveying structure sends the terminal wire clamp to the crimping position. The wire clamp pressing structure descends under the action of hydraulic pressure to crimp the wire clamp and the wire conductor into shape. During the crimping process, it is ensured that the conductor and the terminal are in full contact, the crimping is firm, and there is no virtual connection or damage. Blanking: The crimped cable rotates with the disc to the blanking station, and the blanking component removes the finished product and checks the crimping quality. Beneficial effects

[0020] The present invention provides a wire clip pressing device, which has the following beneficial effects: Through the multi-station indexing disc, power source sharing design, functional modular integration and automated process optimization, the device significantly improves the wire clip pressing efficiency by about 30%-50%, while reducing the device complexity and control difficulty. Its high-precision wire stripping and wire arranging ability, hydraulic pressing stability and flexible station expandability can meet the high-quality and mass production requirements of cable terminal crimping in industrial scenarios. Specifically, it has the following advantages.

[0021] 1. Multi-station high-efficiency collaborative work, reducing the dependence on the robotic arm. By integrating processes such as loading, wire stripping, wire arranging, pressing, and blanking through a multi-station disc, the indexing component drives the disc to rotate intermittently to achieve automatic process switching. Compared with traditional robotic arms that need to frequently adjust the posture and stroke, the action time is significantly shortened.

[0022] 2. Adopting the power source sharing design, the indexing component and the wire clip pressing structure share the same power source. The power is split by using a gearbox and an intermittent driver to synchronously complete the disc indexing and pressing actions. This not only reduces energy consumption but also avoids timing conflicts caused by multiple power sources, improves the action coordination, and cooperates with the photoelectric sensor for precise positioning to ensure accurate alignment of each station and reduce the waiting time caused by positioning errors.

[0023] 3. There is a wire arranging station, and the wire arranger adapts to clamp: The opposing rollers cooperate with the opposing pulling elastic blocks, and the spring and electromagnet are used to achieve automatic clamping and loosening to ensure that the copper wires at the head end of the cable are neatly arranged, reducing loose wires and bending.

[0024] 4. The pressing structure adopts hydraulic linkage. The arc-deficient semi-gear cooperates with the reciprocating rack to drive the hydraulic system, making the action of the pressing die strictly synchronous with the disc indexing. The hydraulic oil circuit buffer design avoids impact, ensuring a smooth pressing process and uniform force.

[0025] 5. Adopting a modular architecture: The wire stripper, wire arranger, pressing structure, etc. are independently modular designed, which is convenient for disassembly and maintenance. An inspection door is set on the wire clip pressing rack to facilitate the maintenance of internal components.

[0026] 6. Multi-station expandability: The number of stations of the multi-station disc can be flexibly adjusted according to process requirements. For example, adding a detection station, through the indexing angle matching of the indexing component, it can adapt to complex process flows. Combined with the power reuse design, the indexing component can be linked with various functional structures, making full use of the redundant power of the indexing motor and reducing the need for independent drive units.

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0040] Please refer to Figures 1-11 , the present invention provides an implementation solution: In the process of modern electrical cable connection, in order to facilitate the connection and use of the cable, a pressed terminal is usually pressed at the head end of the cable, and the cable can be conveniently connected and used through the pressed terminal. At present, the automatic wire clamp pressing equipment often uses a robotic arm for the feeding and unloading operations of the cable. Although the introduction of the robotic arm can improve the efficiency of wire clamp pressing, since the robotic arm needs to measure the length of the cable and adjust the posture of the cable, high requirements are imposed on the control accuracy and motion control of the robotic arm, which not only increases the control work difficulty of the equipment, but also the robotic arm needs to complete two operations of feeding and unloading, resulting in an increase in the stroke length of the robotic arm, thus reducing the efficiency of the wire clamp pressing work.

[0041] Embodiment 1: To address the above problems, the present application discloses a wire clip pressing device, which includes a wire clip pressing frame 1. The wire clip pressing frame 1 is a frame with a polygonal structure, serving as the main support of the device. On one side of the wire clip pressing frame 1, a control box 11 is provided. A multi-station pressing mechanism 3 is arranged on the wire clip pressing frame 1, and a wire clip pressing structure 2 is arranged on one side of the multi-station pressing mechanism 3. The control box 11 serves as the control center and the human-machine interface, through which the wire clip pressing structure 2 and the multi-station pressing mechanism 3 can be controlled; According to the attached drawings of the specification Figure 1 - Drawing Figure 11 It can be seen that the above multi-station pressing mechanism 3 is composed of a multi-station disk 31 driven by an indexing component 35, a multi-functional control structure corresponding to the multi-station disk 31, and a photoelectric sensor 32 for detecting the indexing angle of the multi-station disk 31; Specifically, the above wire clip pressing frame 1 is provided with a rotating slot 12 corresponding to the multi-station disk 31. An indexing component 35 is arranged inside the wire clip pressing frame 1 to perform indexing control on the multi-station disk 31. The multi-station disk 31 is at least equally divided into a feeding station, a wire stripping station, a wire arranging station, a pressing station, and a discharging station. The single rotation angle of the indexing component 35 corresponds to the angle between adjacent stations. The multi-functional control structure is distributed corresponding to the above-mentioned wire arranging station, wire stripping station, and pressing station, and performs operations of wire arranging, wire stripping, and auxiliary pressing respectively. The number of photoelectric sensors 32 corresponds to the number of stations of the multi-station disk 31, and they are distributed on the outer periphery of the multi-station disk 31 corresponding to multiple stations respectively. Whenever the multi-station disk 31 rotates once, its next station will rotate to the position corresponding to the photoelectric sensor 32; According to the attached drawings of the specification Figure 1 - Drawing Figure 11 It can be seen that the above multi-functional control structure includes a wire arranger 33 and a wire stripper 34. The wire stripper 34 is arranged corresponding to the wire stripping station, and the wire stripper 34 strips the head end of the cable passing through the wire stripping station. The wire arranger 33 is arranged corresponding to the wire arranging station, and the wire arranger 33 combs the head end of the cable on the wire arranging station; According to the attached drawings of the specification Figure 1 - Drawing Figure 11 It can be seen that the above wire clip pressing structure 2 is arranged corresponding to the pressing station. The wire clip pressing structure 2 presses the passing cable and wire clip. The wire clip pressing structure 2 and the indexing component 35 adopt the same power source. Furthermore, a conveying structure 4 is also arranged on the wire clip pressing frame 1. The conveying structure 4 is used to support and convey the wire clip through one side of the multi-station disk 31. The end of the conveying structure 4 corresponds to the pressing station on the multi-station disk 31. Terminal wire clips arranged in a chain are placed on the conveying structure 4. Under the action of the conveying structure 4, the terminal wire clips are conveyed to the lower part of the wire clip pressing structure 2, and the wire clip pressing structure 2 presses the terminal wire clips and the cable.

[0042] According to the appended description Figure 1 - Appendix Figure 4 It can be known that the above-mentioned wire clip pressing frame 1 matches the number of workstations of the multi-station disc 31 for a polygonal box body. At least one side of the wire clip pressing frame 1 is provided with a maintenance door 13. The rotating slot 12 is a groove with a disc-shaped structure. A feeding component 5 and a blanking component 6 are respectively arranged on the wire clip pressing frame 1 corresponding to the feeding workstation and the blanking workstation. The structure inside the wire clip pressing frame 1 can be conveniently maintained through the maintenance door 13 on the wire clip pressing frame 1. The feeding of the cable and the blanking of the pressed cable can be realized by using the feeding component 5 and the blanking component 6.

[0043] According to the appended description Figure 1 - Appendix Figure 5 It can be known that the above-mentioned wire clip pressing structure 2 includes a guiding frame 21. The guiding frame 21 is installed on the wire clip pressing frame 1 and corresponds to the pressing workstation. A pressing telescopic device 22 is assembled on the guiding frame 21. The telescopic end of the pressing telescopic device 22 is connected with a pressing die 23. The pressing telescopic device 22 is linked with the indexing component 35. In the specific implementation process, the guiding frame 21 serves as the supporting main body of the wire clip pressing structure 2 and the installation basis of the pressing telescopic device 22. The pressing telescopic device 22 completes the pressing work of the cable terminal wire clip by controlling the pressing die 23 to press down. At the same time, the pressing telescopic device 22 can be linked with the indexing component 35. On the one hand, the purpose of reducing energy consumption is achieved through the same power. On the other hand, through the intermittent movement of the indexing component 35, the wire clip pressing structure 2 can match the rotational movement of the multi-station disc 31, improving the accuracy of the pressing action and the rotation of the disc.

[0044] According to the appended description Figure 1 - Appendix Figure 5 It can be known that the above-mentioned indexing component 35 includes an indexing motor 351. The indexing motor 351 is assembled inside the wire clip pressing frame 1. A indexing grooved wheel 352 is connected to the central axis of the multi-station disc 31. The driving end of the indexing motor 351 is connected with a gearbox 353. An arc-deficient driving wheel 354 is connected to the output end of the gearbox 353. The arc-deficient driving wheel 354 is intermittently engaged with the indexing grooved wheel 352. An intermittent driver 355 is also connected to the gearbox 353 and is connected with the pressing telescopic device 22; In the specific implementation process, the indexing motor 351 is used as the power output. When the indexing motor 351 moves, it is transmitted through the gearbox 353. One output end of the gearbox 353 is linked with the indexing grooved wheel 352 through the arc-deficient driving wheel 354. When the short shaft of the arc-deficient driving wheel 354 meshes with the indexing grooved wheel 352 intermittently, it drives the indexing grooved wheel 352 to drive the multi-station disc 31 to rotate. When the short shaft rotates one week, it can drive the multi-station disc 31 to rotate one station. At the same time, the arc-deficient driving wheel 354 cooperates with the intermittent driver 355. When the multi-station disc 31 does not rotate, the power output of the gearbox 353 is used to control the pressing expander 22, so as to control the telescopic movement of the pressing expander 22 and effectively utilize the redundant power during the indexing process.

[0045] Furthermore, according to the attached Figure 1 - attached Figure 5 It can be known that the above intermittent driver 355 includes intermittent gear teeth 3551. An intermittent gear is coaxially arranged with the arc-deficient driving wheel 354 in the gearbox 353. An output gear 3552 is meshed on one side of the intermittent gear. The number of output gears 3552 is at least one pair. An output shaft 3553 is arranged on the output gear 3552. A power frame is arranged on one side of the gearbox 353 to limit the output shaft 3553. In the specific implementation process, the arc-deficient angle of the intermittent gear is the same as that of the arc-deficient driving wheel 354. When the intermittent gear rotates, it intermittently meshes with the output gear 3552, so that the output gear 3552 intermittently drives the output shaft 3553 to rotate. The power frame plays a role in limiting and stabilizing the output shaft 3553. The pressing expander 22 can be driven through the output shaft 3553 to realize power splitting, so that the cooperation between the movement of the pressing expander 22 and the rotation of the multi-station disc 31 is more stable. The number of output shafts 3553 is plural, and the power can be further split to the wire stripper 34 or the wire arranging device 33.

[0046] According to the attached Figure 1 - attached Figure 4 And attached Figure 7 It can be known that in order to be able to split and output the power to the pressing structure, and at the same time, in order to complete the pressing more precisely during the rotation gap of the multi-station disc 31, an arc-deficient half gear 221 is connected to the end of any output shaft 3553. A telescopic sleeve 222 is arranged outside the arc-deficient half gear 221. A pair of reciprocating racks 223 are symmetrically arranged on both sides of the telescopic sleeve 222. The pair of reciprocating racks 223 are respectively meshed with the arc-deficient half gear 221. A telescopic chute 224 is arranged on the power frame to cooperate with the telescopic sleeve 222. A plunger rod 225 is arranged at the end of the telescopic sleeve 222. A push piston is connected to the end of the plunger rod 225. A plunger tube 226 is sleeved outside the plunger rod 225. Hydraulic oil is arranged in the plunger tube 226. In the specific implementation process, power is separated through any output shaft 3553, so that the arc-deficient half gear 221 of any output shaft 3553 meshes with a pair of reciprocating racks 223 on both sides of the telescopic sleeve 222 alternately. Since the arc-deficient half gear 221 has only half teeth, it meshes with the pair of reciprocating racks 223 respectively during operation, thereby enabling the telescopic sleeve 222 to reciprocate on the telescopic chute 224, so that the telescopic sleeve 222 drives the plunger rod 225 to reciprocate. During the reciprocating movement of the plunger rod 225, hydraulic oil is pushed out and withdrawn through the cooperation of the push piston with the plunger tube 226, thereby controlling the telescopic movement of the pressing expander 22 and completing the pressing work on the terminal wire clamp; According to the attached drawings of the specification Figures 1-3 As can be seen, the above-mentioned pressing expander 22 includes a telescopic sleeve 227, the telescopic sleeve 227 is arranged on the guiding frame 21, a pressing guide rod 228 is arranged inside the telescopic sleeve 227, the bottom end of the pressing guide rod 228 is connected to the pressing die 23, one end of the telescopic sleeve 227 is provided with a hydraulic control pipe 229, and the hydraulic control pipe 229 is connected to the plunger tube 226; In the specific implementation process, the telescopic sleeve 227 is used to limit the pressing guide rod 228, and the pressing guide rod 228 can perform piston movement inside the telescopic sleeve 227. During pressing, power is transmitted to the plunger rod 225 through the output shaft 3553. When pressing down, hydraulic oil is pushed into the telescopic sleeve 227 through the plunger tube 226 and the hydraulic control pipe 229, so that the pressing guide rod 228 pushes the pressing die 23 down to complete the pressing. When lifting, the plunger tube 226 is controlled to be in a negative pressure state through the plunger rod 225, and the hydraulic oil flows back from the hydraulic control pipe 229 to the plunger tube 226, so that the inside of the telescopic sleeve 227 is in a negative pressure state, and the pressing guide rod 228 drives the pressing die 23 to lift to complete the pressing.

[0047] According to the attached drawings of the specification Figure 1 - attached drawings Figure 4 and attached drawings Figure 8 As can be seen, the above-mentioned wire stripper 34 includes a wire stripping roller 341, a control guide rail 342 is arranged on the wire stripping roller 341, a pair of relatively moving wire stripping cutter rollers 343 are assembled on the control guide rail 342, a groove opening is arranged at the end of the wire stripping cutter roller 343, the wire stripping roller 341 is installed on the wire stripping machine housing 344 through a wire stripping shaft, a wire stripping wheel set 345 connected to the wire stripping shaft is arranged inside the wire stripping machine housing 344, and the wire stripping wheel set 345 is driven and controlled by a wire stripping motor 346; In the specific implementation process, the wire stripping roller 341 is controlled to rotate by the wire stripping shaft. During wire stripping, the head end of the cable at the wire stripping station is inserted into the middle of the control guide rail 342 of the wire stripping roller 341. The control guide rail 342 drives a pair of wire stripping roller cutters 343 to move relative to each other, so that the grooves of the pair of wire stripping roller cutters 343 respectively clamp a section of the outer skin of the head end of the cable. Then, the wire stripping wheel set 345 is driven to rotate by the wire stripping shaft. The wire stripping wheel set 345 increases the output torque through deceleration. Further, the wire stripping roller 341 drives the control guide rail 342 to rotate. Under the action of the control guide rail 342, the pair of wire stripping roller cutters 343 rotate around the cable as the center. The outer skin of the cable is cut by using the grooves of the pair of wire stripping roller cutters 343 as the cutting edges.

The wire arranging chuck drives the rotation through the movable shaft. At the same time, the wire arranging chuck and the movable shaft are stabilized by the housing. The housing and the operating motor 332 are integrated structures and can move synchronously on the telescopic track 331. When the cable moves to the wire arranging station, the movement of the wire arranging chuck is controlled by the telescopic track 331 to reach the position. A pair of clamping rollers 333 are controlled to relatively clamp the head end of the cable through the pulling blocks. Then, the movement of the wire arranging roller is controlled by the telescopic track 331. At the same time, the scattered wire heads are sorted together by using the rotation movement of the wire arranging chuck until the wire arranging roller completely disengages from the head end of the cable; Furthermore, the above-mentioned pulling block includes a support track 334. The support track 334 is arranged on the wire arranging chuck. A pair of pulling sliders 335 are arranged on both sides of the support track 334.

The pair of pulling sliders 335 and both ends of the support track 334 are connected through a pair of springs 337; In the specific implementation process, when the head end of the cable is not clamped, a pair of electromagnets 336 generate magnetic force to attract the magnets on a pair of opposing sliders 335, so that the pair of electromagnets 336 attract the pair of opposing sliders 335 to move towards both ends of the support rail 334, thereby pulling apart a pair of clamping rollers 333 and compressing a pair of springs 337. When it is necessary to arrange the cable head end, the pair of electromagnets 336 are cut off, and then the pair of springs 337 are used to push the pair of opposing sliders 335 to move in the opposite direction, so that the pair of opposing sliders 335 drive the pair of clamping rollers 333 to move relatively to clamp the exposed cable head end.

[0049] According to the attached drawings of the specification Figure 1 - drawing Figure 4 and drawing Figure 10 It can be seen that the multi-station disk 31 is a disk-shaped plate.

The adjusting push rod 313 can be used to control the linear movement of the loading seat 312 in the loading slot 311. During loading, the cable is pushed into the loading seat 312 by pushing for feeding. Then, a long slot matching the diameter of the cable is arranged on the loading seat 312, so that the cable is arranged along the axis of the loading seat 312. Then, the electric clamping parts on the clamping seat are used to fasten both ends of the cable. During pressing, the stripped cable head end is inserted into the terminal wire clamp by the forward extension of the loading seat 312, and then pressing can be carried out. The control is convenient and simple.

[0050] According to the attached drawings of the specification Figure 1 - drawing Figure 4 and drawing Figure 11 It can be seen that the conveying structure 4 includes a belt conveyor 41.

The width of the belt conveyor matches the width of the wire clamps, which plays a role in limiting the wire clamps. The belt conveyor is controlled by a feeding motor 42, and the feeding motor 42 adopts servo control. When the photoelectric sensor 32 corresponding to the pressing station detects that the multi-station disc 31 has rotated into place, the feeding motor 42 stops through servo control. At this time, a terminal wire clamp is pushed out and entered onto the pressing support platform 43. The pressing support platform 43 is aligned with the pressing station, and then the stripped cable head end is inserted into the terminal wire clamp by controlling the loading seat 312.
