Description

Technical Field

[0001] The present invention relates to the technical field of cold-pressed terminal assembly, and more particularly to a cold-pressed terminal automatic assembly production device. Background Art

[0002] Cold-pressed terminals, also known as solderless terminals or crimped terminals, are components used for electrical connections. They are mainly used for connections between wires and electrical equipment, and between wires. Unlike traditional welding methods, cold-pressed terminals fix the wires inside them through mechanical crimping to achieve electrical connections.

[0003] When the prior art cold-pressed terminal automatic assembly production equipment is in use, the wire is usually inserted into the cold-pressed terminal, and the exposed conductor is inserted into the conductive part of the cold-pressed terminal to ensure that the conductor is completely inserted into the terminal without bending or twisting, and then the cold-pressed terminal is crimped using an electric hydraulic crimping pliers to complete the crimping work of the wire and the cold-pressed terminal.

[0004] In actual use of the existing technology, since it is impossible to ensure that each conductor fits perfectly with the cold-pressed terminal during the crimping process, gaps are generated inside the cold-pressed terminal, making the connection between the cold-pressed terminal and the wire loose, which in turn increases its resistance and reduces the conductivity of the cold-pressed terminal and the wire.

[0005] Therefore, in view of the above technical problems, it is necessary to provide a cold-pressed terminal automatic assembly production equipment. Summary of the invention

[0006] The object of the present invention is to provide a cold-pressed terminal automatic assembly production equipment to solve the above-mentioned problems.

[0007] In order to achieve the above purpose, the technical solution provided by an embodiment of the present invention is as follows: A cold-pressed terminal automatic assembly production equipment comprises a base plate, a pressing end assembly, a conductive agent injection assembly and a trigger, the upper surface of the base plate is fixedly connected to a connecting frame, the upper surface of the connecting frame is fixedly connected to a storage box, the outer surface of the storage box is fixedly installed with an injection tube, the outer surface of the injection tube is installed with a sealing cover, and the upper surface of the base plate is installed with cold-pressed terminals and wires; the pressing end assembly is installed on the upper surface of the base plate, the pressing end assembly comprises a plurality of electric slide rails opened on the upper surface of the base plate, the inner sliding connection of the electric slide rails is provided with an electric slider, the upper surface of the electric slider is fixedly connected with an arc clamping plate, the upper surface of the base plate is provided with a fixing groove, and the inner part of the fixing groove is provided with an electromagnetic plate; the conductive agent injection assembly is installed inside the storage box, the conductive agent injection assembly comprises two conveying pipes fixedly installed on the lower surface of the storage box, one end of the two conveying pipes is fixedly connected with a conical pipe, and the inner part of the conveying pipes is clamped with a sealing plug.

[0008] As a further improvement of the present invention, a discharge port is fixedly connected to the bottom of the conical tube, a sealing ball is clamped inside the discharge port, a connecting rod is fixedly connected between the sealing ball and the sealing plug, a hard sealing sleeve is fixedly installed on the outer surfaces of the sealing plug and the sealing ball, a magnetic block 1 is fixedly installed in the inner cavity of the sealing ball, and the magnetic block 1 is magnetically connected to the electromagnetic plate. The electromagnetic plate attracts the magnetic block 1, so that the sealing ball and the sealing plug move synchronously, thereby controlling the opening and closing of the discharge port, ensuring that the conductive agent can be injected as needed, and avoiding unnecessary leakage or waste.

[0009] As a further improvement of the present invention, a soft sealing sleeve is fixedly connected to the outer surface of the hard sealing sleeve. The hard sealing sleeve is made of a hard sealing material, and the soft sealing sleeve is made of a soft sealing material. The hard sealing sleeve provides the main support and sealing functions, while the soft sealing sleeve can provide additional elastic sealing on the basis of the hard sealing sleeve, adapt to interfaces of different shapes and sizes, and ensure the best sealing effect.

[0010] As a further improvement of the present invention, a telescopic rod 2 is fixedly connected between the sealing plug and the storage box, and a reset spring is sleeved on the outer surface of the telescopic rod 2. One end of the reset spring is connected to the upper surface of the sealing plug, and the other end is connected to the top wall of the inner cavity of the storage box. The interior of the storage box, the conical tube and the feed pipe are filled with a conductive agent. The telescopic rod 2 provides stable support for the sealing plug to ensure that it will not deviate or get stuck during movement, and the reset spring helps the sealing plug to automatically reset after the electromagnet is powered off.

[0011] As a further improvement of the present invention, a telescopic rod 1 is fixedly connected to the bottom of the connecting frame, a push block is fixedly connected to the output shaft end of the telescopic rod 1, a support spring is sleeved on the outer surface of the telescopic rod 1, and an arc-shaped support plate is fixedly connected to the lower surface of the push block. The telescopic rod 1 provides stable support for the push block and the arc-shaped support plate to ensure that the wires can be firmly fixed during the crimping process to prevent them from moving or deforming. The storage box, conical tube and feed tube are pre-filled with conductive agent to ensure that they can be quickly and evenly injected into the connecting gap when needed, thereby improving the conductive performance.

[0012] As a further improvement of the present invention, a second magnetic block is arranged inside the push block, and the second magnetic block is magnetically connected to the electromagnetic plate. An electromagnet is installed on the upper surface of the electromagnetic plate. Through the magnetic connection between the electromagnetic plate and the second magnetic block, the push block and the arc-shaped support plate can be fixed to the wires. When the electromagnetic plate and the second magnetic block repel each other, the repulsive force generated by the second magnetic block enables the push block to quickly return to its original position under the action of a reset spring, so as to prepare for the next operation.

[0013] As a further improvement of the present invention, the upper surface of the base plate is fixedly connected with a support block between the two electric slide rails, and the lower surface of the cold-pressed terminal abuts against the support block so that the cold-pressed terminal plays a supporting role, thereby improving the stability of the crimping of the cold-pressed terminal and the wire.

[0014] As a further improvement of the present invention, a trigger is installed on the outer surface of the conical tube, and the trigger includes a plurality of connecting blocks fixedly installed on the outer surfaces of two conical tubes, and an elastic airbag is installed on the lower surface of the connecting block. A spray gun is fixedly connected to the bottom of the elastic airbag, and the high-pressure gas generated by the elastic airbag when squeezed is sprayed out through the spray gun, guiding the injected conductive agent to fully pass through the gap into the conductor, ensuring that the conductive agent is evenly distributed and improving the conductive performance.

[0015] As a further improvement of the present invention, the trigger piece includes an elastic sleeve fixedly mounted on the outer surface of the elastic airbag, and a plurality of trigger rods are fixedly connected between the inner cavities of the elastic airbag. The trigger rods and the elastic sleeve are both made of elastic material. The elastic sleeve is wrapped around the outside of the elastic airbag, adding an additional sealing layer to prevent gas leakage. The trigger rod can provide additional support and structural strength to the elastic airbag to prevent the elastic airbag from deformation or rupture under high pressure or frequent use.

[0016] As a further improvement of the present invention, the trigger also includes a trigger block fixedly mounted on the outer surface of the arc-shaped clamping plate, and the outer surface of the trigger block is fixedly connected to a silicone pad. When the arc-shaped clamping plate moves, the trigger block squeezes the elastic airbag, triggering it to compress and release gas. At the same time, the silicone pad provides a buffering protection for the trigger block, which can reduce the impact force when the trigger block contacts the elastic airbag and prevent damage to the elastic airbag.

[0017] Compared with the prior art, the advantages of the present invention are: This solution ensures uniform force on the connection between the cold-pressed terminal and the wire through the mutual cooperation of the electric slide rail, the electric slider and the arc-shaped clamp, avoids local stress concentration, enhances the mechanical strength of the connection point, and ensures that the device can be fixed according to the size and shape of the wire, thereby reducing manual intervention and improving production efficiency.

[0018] By starting the electromagnetic plate to generate a magnetic field opposite to that of magnetic block one and magnetic block two, magnetic block two is magnetically connected to the electromagnetic plate, thereby prompting the push block to move downward. At the same time, the support spring, telescopic rod one, fixing groove, push block and arc-shaped support plate cooperate with each other to fix the wire to prevent it from shifting during operation, thereby ensuring the connection quality.

[0019] The electromagnetic plate attracts magnetic block 1, prompting the sealing ball to drive the sealing plug to move downward through the connecting rod, so that the sealing plug ensures its sealing through the hard sealing sleeve and the soft sealing sleeve, and the sealing ball is separated from the discharge port. At the same time, when the arc-shaped clamping plate moves, the elastic airbag is squeezed through the trigger block and the silicone pad, so that the airflow in the elastic airbag is sprayed out through two spray guns, and the conductive agent is guided to be injected into the connection between the cold-pressed terminal and the wire conductor through the crack of the cold-pressed terminal, so that the conductive agent can be evenly injected into the gap between the cold-pressed terminal and the wire, thereby improving the conductivity of the connection point and reducing the contact resistance. The conductive agent is fully filled into the gap through the gas guidance, ensuring coverage without dead angles, improving the conductivity and reducing the contact resistance.

[0020] By starting the electromagnet in the electromagnetic plate to generate the same magnetic field as magnetic block one and magnetic block two, the electromagnetic plate repels magnetic block one and magnetic block two, respectively prompting the sealing ball to drive the sealing plug to move upward through the connecting rod, so that the sealing ball blocks the discharge port, and at the same time the sealing plug moves upward to open the storage box and the feed pipe, allowing the conductive agent in the storage box to enter the feed pipe. When the sealing plug moves, it will drive the telescopic rod two and the reset spring to move, so as to support and reset them, thereby ensuring that the conductive agent will not leak during the transportation process.

[0021] At the same time, the electromagnetic plate prompts the magnetic block 2 to drive the arc support plate and the push block to move upward through the cooperation of the support spring and the telescopic rod 1, thereby releasing the fixation of the wire. At the same time, the hard sealing sleeve and the soft sealing sleeve on the surface of the sealing ball and the sealing plug cooperate with each other to ensure the sealing of the conductive agent during transportation.

[0022] When the electric slide rail and the electric slider complete the crimping, start the electric slide rail and the electric slider to separate the arc-shaped clamping plate from them, so that it can wait until the conductive agent is dry, and then take it out to carry out the next round of crimping of cold-pressed terminals and wires, so that it can adapt to the crimping work of wires and cold-pressed terminals of different sizes and shapes.

Magnetic block 209 also interacts with the electromagnetic plate 304 to control the movement of the push block 206 and the arc support plate 207. When the electromagnetic plate 304 generates a magnetic field, magnetic block 209 is attracted or repelled, prompting the push block 206 to move downward, thereby firmly fixing the wire 103 on the fixing groove 208, preparing for subsequent crimping and conductive agent injection. During reverse operation, the electromagnetic plate 304 generates a magnetic field in the opposite direction, causing magnetic block 209 to be repelled, driving the push block 206 to move upward, and releasing the fixation of the wire 103. The upper surface of the base plate 1 is located between the two electric slide rails 201 and is fixedly connected to the support block 210, and the lower surface of the cold-pressed terminal 102 is in contact with the support block 210.

[0030] Further, the wire 103 is placed on the fixed groove 208, and the ends of the cold-pressed terminal 102 are placed on the two support blocks 210 respectively. The electromagnet in the electromagnetic plate 304 is started to generate magnetism, so that the magnetic block 1 3034 and the magnetic block 209 generate opposite magnetism, attract each other, and the magnetic block 209 drives the push block 206 and the arc support plate 207 to move downward. When the push block 206 moves downward, it drives the telescopic rod 1 204 and the support spring 205 to move, so that the arc support plate 207 fixes the wire 103 on the fixed groove 208, and the electric slide rail 2 01 and the electric slider 202 continue to drive the arc clamping plate 203 to complete the crimping work of the cold-pressed terminal 102 and the wire 103. After the work is completed, the electric slide rail 201 and the electric slider 202 are started to drive the arc clamping plate 203 away from the cold-pressed terminal 102, and at the same time, the electromagnetic plate 304 is started to generate the same magnetic field with the magnetic block 1 3034 and the magnetic block 209, causing them to repel each other, thereby driving the push block 206 and the arc support plate 207 to move upward through the cooperation of the support spring 205 and the telescopic rod 1 204 through the magnetic block 209, thereby releasing the fixation of the wire 103.

[0031] Embodiment 2: Reference Figure 1-Figure 9 , which is a new second embodiment of the present invention. This embodiment is based on the previous embodiment, and the conductive agent injection assembly 3 is installed inside the storage box 104.

[0032] Specifically, the conductive agent injection assembly 3 includes two conveying pipes 301 fixedly installed on the lower surface of the storage box 104, one end of the two conveying pipes 301 is fixedly connected to the conical tube 302, the interior of the conveying pipe 301 is clamped with a sealing plug 303, the sealing plug 303 is connected to the sealing ball 3031 through a connecting rod 305, when the sealing ball 3031 moves, it drives the sealing plug 303 to move together, so as to control the opening and closing of the conveying pipe 301, the bottom of the conical tube 302 is fixedly connected with a discharge port 308, the interior of the discharge port 308 is clamped with a sealing ball 3031, the sealing ball 3031 is mainly used for opening and closing the discharge port 308, when the sealing ball 3031 moves under the action of the electromagnetic plate 304 and the magnetic block 3034, it can open or close the discharge port 308, so as to control the injection of the conductive agent, on the contrary, the sealing ball 3031 can prevent the conductive agent from being discharged from the discharge port 308 in the closed state.

[0033] A connecting rod 305 is fixedly connected between the sealing ball 3031 and the sealing plug 303, a hard sealing sleeve 3032 is fixedly installed on the outer surfaces of the sealing plug 303 and the sealing ball 3031, a magnetic block 3034 is fixedly installed in the inner cavity of the sealing ball 3031, and the magnetic block 3034 is magnetically connected to the electromagnetic plate 304. The magnetic block 3034 refers to a permanent magnet installed in the sealing ball 3031, which is used to interact with the electromagnetic plate 304. When the electromagnetic plate 304 is energized and generates a magnetic field, the magnetic block 3034 will be attracted or repelled, thereby driving the movement of the sealing ball 3031 and the sealing plug 303, so that the magnetic block 3034 pushes the sealing ball 3031 to move downward, opening the discharge port 308, so that the conductive agent can smoothly flow into the gap between the cold-pressed terminal 102 and the wire 103.

[0034] The interior of the storage box 104, the conical tube 302 and the feed pipe 301 are filled with a conductive agent. The conductive agent is a substance that can significantly improve the conductivity of a material. They are usually used to enhance the conductivity of certain materials. The conductive agent can be replaced by materials such as silver-based conductive paste, conductive polymer solution and conductive glue. At the connection between the cold-pressed terminal 102 and the wire 103, the conductive agent can be used to fill the tiny gap that may exist, ensure close contact between the conductor and the cold-pressed terminal 102, reduce contact resistance and improve conductivity.

[0035] The outer surface of the hard sealing sleeve 3032 is fixedly connected with the soft sealing sleeve 3033. The hard sealing sleeve 3032 is made of hard sealing material, and the soft sealing sleeve 3033 is made of soft sealing material. The hard sealing sleeve 3032 is a sealing component made of hard sealing material, which usually has high mechanical strength and wear resistance, and can withstand large pressure and temperature changes, ensuring that the sealing ball 3031 and the sealing plug 303 can maintain their shape without deformation during long-term use, provide stable support and sealing effect, and can be replaced by metal materials, engineering plastics or ceramic materials. The soft sealing sleeve 3033 has good elasticity and flexibility. The soft sealing sleeve 3033 can provide additional elastic sealing on the basis of the hard sealing sleeve 3032, adapt to interfaces of different shapes and sizes, ensure the best sealing effect, and reduce the wear of the sealing ball 3031 and the sealing plug 303, thereby preventing leakage of the conductive agent and ensuring the safety and efficiency of the operation. The soft sealing sleeve 3033 can be replaced by rubber materials, elastomeric materials or composite materials.

[0036] A second telescopic rod 306 is fixedly connected between the sealing plug 303 and the storage box 104. A reset spring 307 is sleeved on the outer surface of the second telescopic rod 306. One end of the reset spring 307 is connected to the upper surface of the sealing plug 303, and the other end is connected to the top wall of the inner cavity of the storage box 104. A trigger 4 is installed on the outer surface of the conical tube 302. The trigger 4 includes a plurality of connecting blocks 401 fixedly installed on the outer surfaces of the two conical tubes 302. An elastic airbag 402 is installed on the lower surface of the connecting block 401. A spray gun 406 is fixedly connected to the bottom of the elastic airbag 402. The elastic airbag 402 is a device that can deform when subjected to pressure and return to its original shape after the pressure is released. It is commonly used to store and release gas. When in use, when the elastic airbag 402 is squeezed by the trigger block 407, the gas is released through the spray gun 406 to guide the conductive agent into the gap between the cold-pressed terminal 102 and the wire 103, ensuring that the conductive agent is evenly distributed and improving the conductivity. When the trigger block 407 squeezes the elastic airbag 402, the gas in the elastic airbag 402 is compressed and released through the spray gun 406, guiding the conductive agent to fill the connecting gap. On the contrary, when the trigger block 407 is away from the elastic airbag 402, the elastic airbag 402 will expand again and inhale new gas for the next operation. The elastic airbag 402 can be replaced by polyurethane and fluororubber materials.

[0037] The trigger member 4 includes an elastic sleeve 404 fixedly mounted on the outer surface of the elastic airbag 402, and a plurality of trigger rods 403 are fixedly connected between the inner cavities of the elastic airbag 402. The trigger rods 403 and the elastic sleeve 404 are both made of elastic material. The trigger rods 403 are used to support the elastic airbag 402 to prevent the elastic airbag 402 from deforming or rupturing under high pressure or frequent use. The trigger rods 403 can be replaced by rubber, polyamide and glass fiber reinforced plastic materials. The elastic sleeve 404 is used to support the elastic airbag 402. Protection, and enhance its sealing to prevent gas leakage, wherein the elastic sleeve 404 can be replaced by materials such as nitrile rubber and chloroprene rubber, and the trigger 4 also includes a trigger block 407 fixedly mounted on the outer surface of the arc-shaped clamping plate 203, and the outer surface of the trigger block 407 is fixedly connected with a silicone pad 4071, which is mainly used to provide buffer protection and increase friction to ensure stable contact between the trigger block 407 and the elastic airbag 402, and it can be replaced by materials such as polyurethane pads, chloroprene rubber pads or nitrile rubber pads.

[0038] Furthermore, the sealing ball 3031 is driven to move downward by the magnetic block 3034. When the sealing ball 3031 moves downward, the connecting rod 305 drives the sealing plug 303 to move downward, so that the sealing plug 303 blocks the feeding pipe 301. At the same time, the sealing ball 3031 opens the discharge port 308, so that the conductive agent in the feeding pipe 301 and the conical tube 302 is injected into the gap on the surface of the cold-pressed terminal 102 through the discharge port 308. During the movement of the arc-shaped clamping plate 203, the trigger block 407 and the silicone pad 4071 above it squeeze the elastic airbag 402 and the elastic sleeve 404, so that the elastic airbag The gas in 402 is sprayed out through two spray guns 406. The sprayed gases are intertwined to guide the injected conductive agent to fully enter the conductor through the gap, ensuring that the conductive agent is evenly distributed and improving the conductive performance. The electromagnetic plate 304 and the magnetic block 1 3034 are started to generate the same magnetic field, causing them to repel each other. The magnetic block 1 3034 drives the sealing ball 3031 to move the sealing plug 303 upward through the connecting rod 305, and resets it through the telescopic rod 2 306 and the reset spring 307, so that the sealing plug 303 enters the storage box 104, and the sealing ball 3031 blocks the discharge port 308.

[0039] The working principle of the present invention is as follows: during use, a wire stripper is used to strip off the insulation layer at both ends of the wire 103 to expose the internal conductor, and then the wire 103 is inserted into the two cold-pressed terminals 102, and then the wire 103 is placed on the fixed groove 208, and the ends of the cold-pressed terminals 102 are respectively placed on two support blocks 210 to provide stable support for subsequent operations, and the electromagnet in the electromagnetic plate 304 is started to generate magnetism, prompting the magnetic block 1 3034 and the magnetic block 209 to generate opposite magnetism and attract each other, prompting the magnetic block 209 to drive the push block 206 and the arc-shaped support plate 207 to move downward. When the push block 206 moves downward, it will drive the telescopic rod 1 204 and the support spring 205 to move, thereby supporting the push block 206, so that the arc-shaped support plate 207 fixes the wire 103 on the fixed groove 208.

[0040] The sealing ball 3031 is driven to move downward by the magnetic block 3034. When the sealing ball 3031 moves downward, the sealing plug 303 is driven to move downward by the connecting rod 305, so that the sealing plug 303 blocks the feeding pipe 301. At the same time, the sealing ball 3031 opens the discharge port 308, so that the conductive agent in the feeding pipe 301 and the tapered tube 302 is injected into the gap on the surface of the cold-pressed terminal 102 through the discharge port 308. During the movement of the arc-shaped clamping plate 203, the trigger block 407 and the silicone pad 4071 above it squeeze the elastic airbag 402 and the elastic sleeve 404, so that the gas in the elastic airbag 402 is sprayed out through the two spray guns 406. The sprayed gases are intertwined to guide the injected conductive agent to fully pass through the gap into the conductor, thereby ensuring that the conductive agent is evenly distributed and improving the conductive performance. Finally, the gas flows out from both ends of the cold-pressed terminal 102.

[0041] At the same time, when the sealing plug 303 moves downward, it will drive the telescopic rod 2 306 and the return spring 307 to move, so as to support the sealing plug 303 and ensure the stability of the sealing plug 303. At the same time, the electric slide rail 201 and the electric slider 202 continue to drive the arc clamping plate 203 to complete the crimping work of the cold-pressed terminal 102 and the wire 103.

[0042] After the work is completed, the electric slide rail 201 and the electric slider 202 are started to drive the arc clamping plate 203 away from the cold-pressed terminal 102. At this time, the trigger block 407 and the silicone pad 4071 drive the elastic airbag 402 to reset through the cooperation of the trigger rod 403 and the elastic sleeve 404. At the same time, the gas enters the elastic airbag 402 through the spray gun 406 to make the gas in the elastic airbag 402 sufficient. Then the electromagnetic plate 304 is started to generate the same magnetic field with the magnetic block 1 3034 and the magnetic block 209, so that they repel each other, thereby driving the push block 206 and the arc support plate 207 through the magnetic block 209. By the cooperation of the support spring 205 and the telescopic rod 1 204 to move upward, the fixation of the wire 103 is released, and the magnetic block 1 3034 drives the sealing ball 3031 to drive the sealing plug 303 upward through the connecting rod 305, and resets it through the telescopic rod 2 306 and the reset spring 307, so that the sealing plug 303 enters the storage box 104, and the sealing ball 3031 blocks the discharge port 308 to prevent the conductive agent from leaking. Then, after waiting for the conductive agent to dry, the cold-pressed terminal 102 and the wire 103 are taken out to prepare for the next round of crimping of the cold-pressed terminal 102 and the wire 103.

[0043] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
