Description

Technical Field

[0001] This utility model relates to the field of riveting machines, specifically to an automatic riveting machine for wire terminals. Background Technology

[0002] Wire crimping terminals, as important electrical connection components, are widely used in many key fields, including but not limited to communication equipment, rail transportation, lighting systems, building intelligence, automotive manufacturing, and other electrical and electronic applications. These terminals are typically used to connect wires or conductors to electronic devices, circuit boards, or other electrical components to ensure a stable flow of current between connection points, thereby enabling the normal operation of the circuit. Wire crimping terminals not only play a crucial role in various industrial applications but also significantly contribute to improving the stability and efficiency of electrical systems. The basic structure of these wire crimping terminals includes a pin bracket and a crimp nut mounted on the pin bracket; therefore, a crimping mechanism is typically used to crimp the crimp nut onto the pin bracket.

[0003] Existing wire terminal crimping machines typically include manual and semi-automatic models. The main components of a wire terminal crimping machine include a main frame, a conveying system, a riveting device, and a control system. In practical use, the wire terminal crimping machine uses a conveying system to transport the terminals to be processed to a designated position, where they are fixed and positioned by fixtures. Then, the riveting device completes the riveting process under pressure. Finally, the riveted products are output through the conveying system.

[0004] However, although existing automatic riveting machines for wire terminals have been widely used in many fields, there are still some shortcomings that limit their further development and application. Existing manual or semi-automatic riveting machines still require frequent manual adjustments to loading and unloading during the riveting process of pin brackets and rivet nuts. This not only increases the burden on operators but also reduces production efficiency and affects the production and use of the riveting machine. Furthermore, the manual control of the existing riveting process can easily lead to unstable riveting quality, thereby affecting the production efficiency and product quality of wire terminals. Utility Model Content

[0005] The purpose of this invention is to address the above-mentioned deficiencies by providing an automatic riveting machine for wire terminals. This addresses the technical problem in the prior art where the existing riveting machines have a low degree of automation in feeding and riveting, which affects the production efficiency and quality of wire terminals.

[0006] The objective of this utility model is achieved through the following means:

[0007] An automatic crimping machine for wire terminals includes a cabinet and a top plate mounted on the cabinet. A controller and a worktable are mounted on the top plate. The top plate has a first vibratory feeder for transmitting pin supports and a second vibratory feeder for transmitting crimping nuts. A conveyor seat is mounted on the worktable, with a first conveying channel communicating with the first vibratory feeder and a second conveying channel communicating with the second vibratory feeder. Along the transmission direction of the first conveying channel, the worktable is sequentially equipped with a first feeding mechanism for pin supports, a conveying mechanism for moving pin supports along the first conveying channel, and a positioning mechanism. A crimping station is formed in the middle of the first conveying channel. The worktable has a second feeding mechanism for conveying crimping nuts from the second conveying channel to the first conveying channel. The top plate has a crimping mechanism for crimping the crimping nuts to the pin supports. The worktable has a detection device for detecting the crimped wire terminals.

[0008] Further as described above, the first conveying channel and the second conveying channel extend along the X-axis direction. A steering block is provided on the worktable to connect one end of the second conveying channel with the first conveying channel. A steering groove is formed on the steering block to connect the first conveying channel and the second conveying channel. The second feeding mechanism includes a top-loading cylinder and a top-ejecting rod. The telescopic end of the top-loading cylinder is connected to one end of the top-ejecting rod, and the other end of the top-ejecting rod extends into the steering groove.

[0009] The first conveying channel and the second conveying channel are connected by a steering groove. When the ejector rod driven by the top cylinder moves towards the steering groove, the rivet nut conveyed by the second conveying channel enters the first conveying channel and pairs with the pin bracket. This further improves the automated control of conveying and feeding, and improves production efficiency and the quality of feeding and riveting.

[0010] Further as described above, the first feeding mechanism includes an ejector cylinder, a feeding cylinder, and a positioning seat for positioning the pin support. The positioning seat has a feeding channel that communicates with the first vibrating plate and the first conveying channel. The telescopic end of the ejector cylinder extends to the feeding channel. The ejector cylinder ejects the pin support to the feeding end of the first conveying channel through a telescopic rod. The telescopic end of the feeding cylinder is flush with the extension conveying direction of the first conveying channel.

[0011] The feeding channel on the positioning seat is used to temporarily store the pin bracket, so that the pin bracket can be pushed out by the set ejection cylinder and enter the first conveying channel. The feeding cylinder moves the pin bracket along the first conveying channel, further ensuring the automated control of feeding and improving the stability of feeding and production efficiency.

[0012] Specifically, both the steering seat and the positioning seat are equipped with incoming material detection sensors.

[0013] Further, as described above, the conveying mechanism includes a guide seat, a feeding cylinder, a feeding frame, and several conveying supports mounted on the conveying frame. The telescopic end of the feeding cylinder extends along the transmission direction of the first conveying channel and is connected to the feeding frame. The guide seat is mounted on the workbench and has a guide groove formed on it for matching and mounting the feeding frame. The guide groove extends along the transmission direction of the first conveying channel. One end of the conveying support is hinged to the feeding frame, and the other end of the conveying support extends into the interior of the first conveying channel. An inclined chamfer is formed on the side of the conveying support near the feed end of the first conveying channel.

[0014] The conveying bracket and the feeding frame are hinged together by a hinge, so that the conveying bracket can rotate along the hinge. Specifically, by tilting and chamfering one side of the conveying bracket, the feeding cylinder in the previous process rotates and tilts to avoid the movement of the pin bracket, so that the pin bracket can be transferred along the first conveying channel.

[0015] Driven by the feeding cylinder, the feeding rack can drive the pin support to be transported along the first conveying channel through the conveying bracket, so that it can be transported in an intermittent step-by-step manner.

[0016] Furthermore, as described above, the feeding rack is provided with a mounting groove for mounting the conveying bracket, and the feeding rack is provided with a pressure plate for pressing against the conveying bracket.

[0017] Specifically, the conveyor bracket and the mounting groove are hinged together by a hinge. The side of the conveyor bracket closest to the feeding cylinder contacts the inner wall of the mounting groove to form a limit, and the other side of the conveyor bracket forms a gap with the inner wall of the mounting groove, so that the conveyor bracket can rotate in the opposite direction of the chamfer, that is, in the direction of the gap.

[0018] The pressure plate prevents the conveyor support from moving up and down, so that the conveyor support only swings in the direction of conveying the first conveying channel.

[0019] Furthermore, as described above, the side of the conveyor seat is provided with clamping blocks that match the number of conveying brackets. The clamping blocks are evenly distributed along the extension direction of the first conveying channel, with one end of the clamping block extending into the first conveying channel. The conveyor seat is provided with a limiting plate for limiting the pin brackets, and the bottom of the limiting plate has a limiting part for matching the pin brackets.

[0020] Specifically, the number of clamping blocks and conveying brackets are matched. The conveying bracket is limited by contacting the mounting groove on one side. When the feeding cylinder extends, the conveying bracket moves the pin bracket along the conveying direction of the first conveying channel. Each pin bracket moves closer to a clamping block. The clamping block extends into the first conveying channel and clamps and limits the pin bracket. When the feeding cylinder retracts, due to the limitation of the pin bracket by the clamping block, the conveying bracket contacts the pin bracket through the chamfer on its side and swings along the gap direction to avoid it, thereby passing through the pin bracket to reset and convey the next material.

[0021] Further, as described above, the positioning mechanism includes a positioning cylinder, an extrusion block, a lifting seat, and a positioning column disposed on the lifting seat. A sliding groove is provided at the bottom of the conveying seat, the lifting seat is disposed in the sliding groove and can move up and down along the sliding groove, the conveying seat is provided with a positioning groove that communicates with the sliding groove and the first conveying channel, the positioning column is installed on the top of the lifting seat and can move along the positioning groove toward the first conveying channel, the positioning cylinder is installed on the worktable, and the telescopic end of the positioning cylinder is connected to the extrusion block, one end of the extrusion block extends toward the sliding groove of the conveying seat and contacts the bottom of the lifting seat, and the end of the extrusion block extending toward the sliding groove of the conveying seat forms an inclined extrusion part.

[0022] The extrusion block is driven by the positioning cylinder to move to the first conveying channel. The bottom of the lifting seat is squeezed by the extrusion block, which drives the positioning column to push out along the positioning groove, thereby positioning the pin bracket. Then, the riveting mechanism accurately and stably rivets the rivet nut to the pin bracket to form a crimped terminal, improving the quality and efficiency of riveting.

[0023] Furthermore, as described above, a feeding cylinder is connected to the side of the workbench, and the telescopic end of the feeding cylinder is connected to a finished product hopper and a defective hopper. Both the finished product hopper and the defective hopper are provided with feeding ports that communicate with the first conveying channel.

[0024] The riveted wire terminals are photographed and inspected by a detection device, and the controller analyzes whether the wire terminals are finished products or defective products. This allows the corresponding finished product hopper or defective hopper to be connected to the first conveying channel, further improving the automation control and production efficiency of the riveting machine.

[0025] Furthermore, the detection device includes a detection camera and a display for detecting the crimped terminals on the conveyor seat. The detection camera is mounted on the top plate, and the detection end of the detection camera extends toward the output end of the conveyor seat.

[0026] The beneficial effects of this utility model are as follows: The first and second vibratory feeders are used for efficient and automatic transmission of pin supports and rivet nuts, reducing manual intervention and improving production efficiency and automation. The design of the first and second conveying channels enables precise material guidance and transmission, ensuring smooth production processes. The first feeding mechanism accurately feeds the pin supports from the vibratory feeder into the first conveying channel, and the conveying mechanism ensures the pin supports are stably transmitted along a predetermined path to the riveting station. The positioning mechanism precisely positions the pin supports at the riveting station. The second feeding mechanism accurately transmits the rivet nuts from the second conveying channel to the riveting station where they are combined with the pin supports, achieving pairing of the rivet nuts and pin supports. The riveting mechanism then rivets the rivet nuts and pin supports at the riveting station to form crimped terminals, ensuring uniformity and reliability of the riveting process. The detection device inspects the crimped terminals, enabling timely detection and rejection of defective products, ensuring the quality of the final product, and further improving automation and production efficiency.

[0043] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0044] In this embodiment, refer to Figures 1-10 The automatic crimping machine for wire terminals, specifically implemented therein, includes a cabinet 1 and a top plate 2 mounted on the cabinet 1. A controller 3 is mounted on the top plate 2, and a worktable 4 is mounted on the top plate 2. The top plate 2 is equipped with a first vibrating plate 5 for transmitting pin supports and a second vibrating plate 6 for transmitting crimping nuts. A conveyor seat 7 is mounted on the worktable 4, with a first conveying channel 71 communicating with the first vibrating plate 5 and a second conveying channel 8 communicating with the second vibrating plate 6. The machine moves along the first conveying channel 71 on the worktable 4. The transmission direction of 1 is sequentially provided with a first feeding mechanism 13 for pin brackets, a conveying mechanism 14 for moving pin brackets along the first conveying channel 71 and a positioning mechanism 15. A riveting station is formed in the middle of the first conveying channel 71. The worktable 4 is provided with a second feeding mechanism 16 for conveying the riveting nut on the second conveying channel 8 to the first conveying channel 71. The top plate 2 is provided with a riveting mechanism 9 for riveting the riveting nut to the pin bracket. The worktable 4 is provided with a detection device for detecting the riveted wire terminals.

[0045] Reference Figures 1-6The first conveying channel 71 and the second conveying channel 8 extend along the X-axis. A deflector block 17 is provided on the worktable 4 to connect one end of the second conveying channel 8 to the first conveying channel 71. A deflector groove 18 is formed on the deflector block 17 to connect the first conveying channel 71 and the second conveying channel 8. (Refer to...) Figure 8 The second feeding mechanism 16 includes a top-loading cylinder 161 and a top-ejecting rod 162. The telescopic end of the top-loading cylinder 161 is connected to one end of the top-ejecting rod 162, and the other end of the top-ejecting rod 162 extends into the turning groove 18. The turning groove 18 connects the first conveying channel 71 and the second conveying channel 8, so that when the top-loading cylinder 161 drives the top-ejecting rod 162 to move into the turning groove 18, the rivet nuts transmitted by the second conveying channel 8 enter the first conveying channel 71 and pair with the pin bracket, further improving the automated control drive of the feeding and conveying, and improving production efficiency and the quality of feeding and riveting.

[0046] Reference Figure 6 and Figure 7 The first feeding mechanism 13 includes an ejector cylinder 131, a feeding cylinder 132, and a positioning seat 133 for positioning the pin support. The positioning seat 133 has a feeding channel 134 that communicates with the first vibrating plate 5 and the first conveying channel 71. The telescopic end of the ejector cylinder 131 extends to the feeding channel 134. The ejector cylinder 131 ejects the pin support to the feeding end of the first conveying channel 71 through a telescopic rod. The telescopic end of the feeding cylinder 132 is flush with the extending conveying direction of the first conveying channel 71.

[0047] The feeding channel 134 on the positioning seat 133 is used to temporarily store the pin bracket, so that the pin bracket can be pushed out by the ejection cylinder 131 and enter the first conveying channel 71. The feeding cylinder 132 moves the pin bracket along the first conveying channel 71, further ensuring the automated control of feeding and improving the stability and production efficiency of feeding.

[0048] Specifically, both the steering seat and the positioning seat 133 are equipped with incoming material detection sensors.

[0049] Reference Figures 4-6The conveying mechanism 14 includes a guide seat 141, a feeding cylinder 142, a feeding frame 143, and a plurality of conveying supports 144 disposed on the conveying frame. The telescopic end of the feeding cylinder 142 extends along the conveying direction of the first conveying channel 71 and is connected to the feeding frame 143. The guide seat 141 is mounted on the workbench 4 and has a guide groove 145 for matching and mounting the feeding frame 143. The guide groove 145 extends along the conveying direction of the first conveying channel 71. One end of the conveying support 144 is hinged to the feeding frame 143, and the other end of the conveying support 144 extends into the first conveying channel 71. The side of the conveying support 144 near the feed end of the first conveying channel 71 has an inclined chamfer.

[0050] The conveying bracket 144 is hinged to the feeding rack 143 by a hinge, so that the conveying bracket 144 can rotate along the hinge. Specifically, by the inclined chamfer on one side of the conveying bracket 144, the feeding cylinder 132 rotates and tilts to avoid the movement of the pin bracket in the previous process, so that the pin bracket can be transferred along the first conveying channel 71.

[0051] Driven by the feeding cylinder 142, the feeding rack 143 can drive the pin support to be transported along the first conveying channel 71 through the conveying bracket 144, so that it can be transported in an intermittent step-by-step manner.

[0052] The feeding rack 143 is provided with a mounting groove 146 for mounting the conveying bracket 144, and the feeding rack 143 is provided with a pressure plate 19 for pressing against the conveying bracket 144.

[0053] Specifically, the conveying bracket 144 and the mounting groove 146 are hinged together by a hinge. The side of the conveying bracket 144 near the feeding cylinder 132 contacts the inner wall of the mounting groove 146 to form a limit, and the other side of the conveying bracket 144 forms a gap with the inner wall of the mounting groove 146, so that the conveying bracket 144 can rotate in the opposite direction of the chamfer, that is, in the direction of the gap.

[0054] The pressure plate 19 is set to prevent the conveyor support 144 from moving up and down, so that the conveyor support 144 only swings in the conveying direction of the first conveying channel 71.

[0055] Reference Figures 5-6 The side of the conveyor seat 7 is provided with clamping blocks 22 that match the number of conveying brackets 144. The clamping blocks 22 are evenly distributed along the extension direction of the first conveying channel 71, and one end of the clamping block 22 extends into the first conveying channel 71. Figure 10 The conveyor seat 7 is provided with a limiting plate 23 for limiting the pin bracket, and the bottom of the limiting plate 23 is formed with a limiting part for matching the pin bracket.

[0056] Specifically, the number of clamping blocks 22 and conveying brackets 144 are matched. The conveying bracket 144 is limited by contacting the mounting groove 146 on one side. When the feeding cylinder 142 extends, the conveying bracket 144 moves the pin brackets along the conveying direction of the first conveying channel 71. Each pin bracket moves closer to a clamping block 22. The clamping block 22 extends into the first conveying channel 71 and clamps and limits the pin brackets. At this time, when the feeding cylinder 142 retracts, due to the limitation of the pin brackets by the clamping blocks 22, the conveying bracket 144 contacts the pin brackets through the chamfer on its side and swings along the gap direction to avoid them, thereby passing through the pin brackets to reset and convey the next material.

[0057] Reference Figures 6-9 The positioning mechanism 15 includes a positioning cylinder 151, a pressing block 152, a lifting seat 153, and a positioning column 154 disposed on the lifting seat 153. The bottom of the conveying seat 7 is provided with a sliding groove 72. The lifting seat 153 is disposed in the sliding groove 72 and can move up and down along the sliding groove 72. The conveying seat 7 is provided with a positioning groove 73 that communicates with the sliding groove 72 and the first conveying channel 71. The positioning column 154 is installed on the top of the lifting seat 153 and can move along the positioning groove 73 toward the first conveying channel 71. The positioning cylinder 151 is installed on the worktable 4, and the telescopic end of the positioning cylinder 151 is connected to the pressing block 152. One end of the pressing block 152 extends toward the sliding groove 72 of the conveying seat 7 and contacts the bottom of the lifting seat 153. The end of the pressing block 152 extending toward the sliding groove 72 of the conveying seat 7 forms an inclined pressing part.

[0058] The positioning cylinder 151 drives the extrusion block 152 to move towards the first conveying channel 71. The bottom of the lifting seat 153 is squeezed by the extrusion block 152, which drives the positioning column 154 to push out along the positioning groove 73, thereby positioning the pin bracket. Then, the riveting mechanism 9 precisely and stably rivets the rivet nut to the pin bracket to form a crimped terminal, improving the quality and efficiency of riveting.

[0059] Reference Figure 3 The side of the workbench 4 is connected to a feeding cylinder 10. The telescopic end of the feeding cylinder 10 is connected to a finished product hopper 11 and a defective hopper 12. Both the finished product hopper 11 and the defective hopper 12 are provided with feeding ports that communicate with the first conveying channel 71.

[0060] The detection device takes pictures of the crimped terminals after riveting and analyzes whether the crimped terminals are finished products or defective products through the controller 3. Then, the corresponding finished product hopper 11 or defective hopper 12 is connected to the first conveying channel 71 to further improve the automation control and production efficiency of the riveting machine.

[0061] The detection device includes a detection camera 20 and a display 21 for detecting the crimped terminals on the conveyor seat 7. The detection camera 20 is mounted on the top plate 2, and the detection end of the detection camera 20 extends toward the output end of the conveyor seat 7.

[0062] Specifically, the riveting mechanism 9 is the core component of the equipment, responsible for firmly riveting the rivet nut onto the pin bracket to complete the fabrication of the crimp terminal. The riveting mechanism 9 is a conventional technical means in this field and will not be described in detail here.

[0063] The specific action process in this embodiment is as follows:

[0064] Feeding: The first vibrating plate 5 and the second vibrating plate 6 are used for efficient and automatic transmission of pin brackets and rivet nuts. The first vibrating plate 5 and the second vibrating plate 6 have a first feeding channel and a second feeding channel connected along the tangent. The first feeding channel is connected to the first conveying channel 71 through the feeding channel 134 of the positioning seat 133. Specifically, the pin bracket on the feeding channel 134 is pushed out by the ejector cylinder 131 and enters the feeding end of the first conveying channel 71. The ejector pin bracket is fed along the first conveying channel 71 to the two conveying brackets 144 by the feeding cylinder 132. The feeding cylinder 142 drives the feeding frame 143 to drive the conveying bracket 144 to move the pin bracket multiple times to enter the riveting station. The rivet nut passes through the second feeding channel and enters the turning groove 18 along the second conveying channel 8. The ejector cylinder 161 drives the ejector rod 162 to transmit the rivet nut in the turning groove 18 to the riveting station combined with the pin bracket, so that the rivet nut and the pin bracket are paired.

[0065] Positioning: The positioning cylinder 151 drives the extrusion block 152 to push out the two positioning pins 154 and expose them on the first conveying channel 71, so that the two positioning pins 154 respectively hold the two sides of the limit pin bracket.

[0066] Riveting: The riveting mechanism 9 is installed on the top plate 2, and the lifting riveting end of the riveting mechanism 9 is set on the riveting station. The lifting riveting end can be driven by the driving component to rivet the rivet nut on the riveting station to the pin bracket and fix it, so as to form a crimped terminal.

[0067] Conveying: The feeding cylinder 142 drives the feeding frame 143 to move part of the conveying bracket 144 multiple times, so that the pin bracket at the feeding end of the first conveying channel 71 is moved to the riveting station, and the riveted wire terminal is conveyed to the detection end of the first conveying channel 71 by the movement of the conveying bracket 144. The detection camera 20 takes pictures of the wire terminal for detection.

[0068] Qualified finished product unloading: The controller 3 analyzes whether the crimped terminal is a qualified finished product or a defective finished product. When the crimped terminal is a qualified product, the unloading cylinder 10 drives the finished product hopper 11 to connect with the first conveying channel 71 to unload the qualified finished product and complete the crimping process of one crimped terminal.

[0069] Defective product unloading: The controller 3 analyzes whether the crimped terminal is a qualified finished product or a defective finished product. When the crimped terminal is a defective product, the unloading cylinder 10 drives the defective hopper 12 to connect with the first conveying channel 71 to unload the defective product and complete the crimping process of one crimped terminal.

[0070] In summary, by pairing the first vibratory plate 5 and the second vibratory plate 6 with the first conveying channel 71 and the second conveying channel 8 respectively, the pin bracket and the rivet nut are respectively used to transport materials. This reduces manual material feeding intervention, improves production efficiency and automation level. The design of the first conveying channel 71 and the second conveying channel 8 enables precise material guidance and transmission, ensuring smooth production process, orderly and continuous material supply, avoiding material blockage or shortage, and improving processing accuracy and efficiency.
