Description

Technical Field

[0001] The present invention relates to the technical field of cold-press terminal assembly, and more specifically, to an automatic assembly production device for cold-press terminals. Background Art

[0002] Cold-press terminals, also known as non-welded terminals or crimp terminals, are components used for electrical connections, mainly for connecting wires to electrical equipment and between wires. Different from traditional welding methods, cold-press terminals fix wires inside them through mechanical crimping to achieve electrical connection.

[0003] When the existing cold-press terminal automatic assembly production equipment is in use, usually a wire is inserted into the cold-press terminal, and the exposed conductor is inserted into the conductive part of the cold-press terminal to ensure that the conductor completely enters the terminal and there is no bending or twisting. Then, an electric hydraulic crimping pliers is used to crimp the cold-press terminal to complete the crimping work of the wire and the cold-press terminal.

[0004] In actual use of the existing technology, since it is impossible to ensure that each conductor fits perfectly with the cold-press terminal during the crimping process of the wire conductor and the cold-press terminal, gaps are generated inside, resulting in loose connection between the cold-press terminal and the wire, further increasing its resistance and reducing the conductivity of the cold-press terminal and the wire.

[0005] Therefore, in view of the above technical problems, it is necessary to provide an automatic assembly production device for cold-press terminals. Summary of the Invention

[0006] The purpose of the present invention is to provide an automatic assembly production device for cold-press terminals to solve the above problems.

[0007] To achieve the above purpose, the technical solution provided by an embodiment of the present invention is as follows:

[0008] An automatic assembly production device for cold-press terminals includes a bottom plate, a terminal pressing assembly, a conductive agent injection assembly, and a trigger member. The upper surface of the bottom plate is fixedly connected with a connecting frame, the upper surface of the connecting frame is fixedly connected with a storage box, a feeding pipe is fixedly installed on the outer surface of the storage box, a sealing cover is installed on the outer surface of the feeding pipe, and a cold-press terminal and a wire are installed on the upper surface of the bottom plate; the terminal pressing assembly is installed on the upper surface of the bottom plate, the terminal pressing assembly includes a plurality of electric slide rails opened on the upper surface of the bottom plate, an electric slider is slidably connected inside the electric slide rail, an arc-shaped clamping plate is fixedly connected to the upper surface of the electric slider, a fixing groove is installed on the upper surface of the bottom plate, and an electromagnetic plate is installed inside the fixing groove; the conductive agent injection assembly is installed inside the storage box, the conductive agent injection assembly includes two feeding pipes fixedly installed on the lower surface of the storage box, one end of the two feeding pipes is fixedly connected with a conical pipe, and a sealing plug is clamped inside the feeding pipe.

[0009] 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. Hard sealing sleeves are fixedly installed on the outer surfaces of the sealing plug and the sealing ball. A first magnetic block is fixedly installed inside the cavity of the sealing ball. The first magnetic block is magnetically connected to the electromagnetic plate. By attracting the first magnetic block with the electromagnetic plate, 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.

[0010] 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, adapting to interfaces of different shapes and sizes to ensure the best sealing effect.

[0011] As a further improvement of the present invention, a second telescopic rod is fixedly connected between the sealing plug and the storage box. A return spring is sleeved on the outer surface of the second telescopic rod. One end of the return 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 storage box, the conical tube and the feed pipe are filled with a conductive agent. The second telescopic rod provides stable support for the sealing plug to ensure that it will not shift or get stuck during movement. The return spring helps the sealing plug to automatically reset after the electromagnet is powered off.

[0012] As a further improvement of the present invention, a first telescopic rod is fixedly connected to the bottom of the connecting frame. A push block is fixedly connected to the output shaft end of the first telescopic rod. A support spring is sleeved on the outer surface of the first telescopic rod. An arc-shaped support plate is fixedly connected to the lower surface of the push block. The first telescopic rod provides stable support for the push block and the arc-shaped support plate to ensure that the wire can be firmly fixed during the crimping process to prevent it from moving or deforming. The storage box, the conical tube and the feed pipe are pre-filled with a conductive agent to ensure that it can be quickly and evenly injected into the connection gap when needed, improving the conductive performance.

[0013] As a further improvement of the present invention, a second magnetic block is arranged inside the push block. 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 fixing of the wire by the push block and the arc-shaped support plate can be realized. When the electromagnetic plate repels the second magnetic block, the repulsive force generated by the second magnetic block enables the push block to quickly return to its original position under the action of the return spring, preparing for the next operation.

[0014] As a further improvement of the present invention, a support block is fixedly connected between the two electric slide rails on the upper surface of the bottom plate, and the lower surface of the cold pressing terminal abuts against the support block, so that the cold pressing terminal plays a supporting role, thereby improving the stability of the crimping between the cold pressing terminal and the wire.

[0015] As a further improvement of the present invention, a trigger member is installed on the outer surface of the conical tube. The trigger member includes a plurality of connecting blocks fixedly installed on the outer surfaces of the two conical tubes. An elastic airbag is installed on the lower surface of the connecting block. The bottom of the elastic airbag is fixedly connected to a spray gun. The high-pressure gas generated when the elastic airbag is squeezed is sprayed out through the spray gun, guiding the injected conductive agent to fully enter the conductor through the gap, ensuring the uniform distribution of the conductive agent and improving the conductive performance.

[0016] As a further improvement of the present invention, the trigger member includes an elastic sleeve fixedly installed on the outer surface of the elastic airbag. A plurality of trigger rods are fixedly connected between the inner cavities of the elastic airbags. Both the trigger rods and the elastic sleeve are made of elastic materials. The elastic sleeve wraps around the outside of the elastic airbag, adding an additional sealing layer to prevent gas leakage. The trigger rods can provide additional support and structural strength to the elastic airbag, preventing the elastic airbag from deforming or rupturing under high pressure or frequent use.

[0017] As a further improvement of the present invention, the trigger member further includes a trigger block fixedly installed on the outer surface of the arc-shaped clamping plate. A silica gel pad is fixedly connected to the outer surface of the trigger block. When the arc-shaped clamping plate moves, the trigger block will squeeze the elastic airbag, triggering its compression and release of gas. At the same time, the silica gel pad provides a buffering and protective effect 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.

[0018] Compared with the prior art, the advantages of the present invention are as follows:

[0019] Through the mutual cooperation of the electric slide rail, the electric slider and the arc-shaped clamping plate, this solution ensures that the force on the connection between the cold pressing terminal and the wire is uniform, 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.

[0020] By starting the electromagnetic plate to generate a magnetic field opposite to that of the first magnetic block and the second magnetic block, the second magnetic block is magnetically connected to the electromagnetic plate, thereby causing the push block to move downward. At the same time, through the mutual cooperation of the support spring, the first telescopic rod, the fixed groove, the push block and the arc-shaped support plate, the wire can be fixed to prevent it from shifting during the operation process and ensure the connection quality.

[0021] The electromagnetic plate attracts the first magnetic block, prompting the sealing ball to drive the sealing plug to move downward through the connecting rod. The sealing plug ensures its sealing performance through the rigid sealing sleeve and the flexible sealing sleeve. 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 silica gel pad, so that the air flow in the elastic airbag is ejected through the 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, improving the conductivity of the connection point, reducing the contact resistance, and guiding the conductive agent to fully fill the gap through the gas, ensuring no dead angle coverage, improving the conductivity, and reducing the contact resistance.

[0022] By activating the electromagnet in the electromagnetic plate to generate the same magnetic field as the first magnetic block and the second magnetic block, the electromagnetic plate repels the first magnetic block and the second magnetic block, respectively prompting the sealing ball to drive the sealing plug to move upward through the connecting rod, blocking the discharge port with the sealing ball. At the same time, the sealing plug moves upward to open the storage box and the feeding pipe, allowing the conductive agent in the storage box to enter the feeding pipe. When the sealing plug moves, it drives the second telescopic rod and the return spring to move, so as to play a role in supporting and resetting, thereby ensuring that the conductive agent will not leak during the transportation process.

[0023] At the same time, the electromagnetic plate prompts the second magnetic block to drive the arc-shaped support plate and the push block to move upward through the mutual cooperation of the support spring and the first telescopic rod, releasing the fixation of the wire. At the same time, the sealing performance during the transportation of the conductive agent is achieved through the mutual cooperation of the rigid sealing sleeve and the flexible sealing sleeve on the surfaces of the sealing ball and the sealing plug.

[0024] When the electric slide rail and the electric slider complete the crimping, activate the electric slide rail and the electric slider to prompt the arc-shaped clamping plate to separate from it, so that after the conductive agent dries, it can be taken out and the next round of crimping work for the cold-pressed terminal and the wire can be carried out, so as to adapt to the crimping work of wires and cold-pressed terminals of different sizes and shapes.

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] Embodiment 1:

[0041] Please refer to Figures 1-9, A cold-press terminal automatic assembly production device, including that the upper surface of the bottom plate 1 is fixedly connected with a connecting frame 101, the upper surface of the connecting frame 101 is fixedly connected with a storage box 104, the outer surface of the storage box 104 is fixedly installed with a feeding pipe 105, the outer surface of the feeding pipe 105 is installed with a sealing cover 106, and the upper surface of the bottom plate 1 is installed with cold-press terminals 102 and electric wires 103.

[0042] Specifically, the terminal pressing assembly 2 is installed on the upper surface of the bottom plate 1. The terminal pressing assembly 2 includes a plurality of electric sliding rails 201 opened on the upper surface of the bottom plate 1. An electric slider 202 is slidably connected inside the electric sliding rail 201. The upper surface of the electric slider 202 is fixedly connected with an arc-shaped clamping plate 203. The upper surface of the bottom plate 1 is installed with a fixing groove 208. An electromagnetic plate 304 is installed inside the fixing groove 208. The electromagnetic plate 304 is a device that uses an electric current passing through a coil to generate a magnetic field. When an electric current passes through the coil, a magnetic field will be generated around it. This magnetic field can attract or repel nearby magnetic materials.

[0043] The bottom of the connecting frame 101 is fixedly connected with a first telescopic rod 204. The output shaft end of the first telescopic rod 204 is fixedly connected with a push block 206. The outer surface of the first telescopic rod 204 is sleeved and connected with a support spring 205. The lower surface of the push block 206 is fixedly connected with an arc-shaped support plate 207. A second magnetic block 209 is arranged inside the push block 206. The second magnetic block 209 is magnetically connected with the electromagnetic plate 304. An electromagnet is installed on the upper surface of the electromagnetic plate 304.

[0044] The second magnetic block 209 refers to another permanent magnet installed inside the push block 206. The second magnetic block 209 also interacts with the electromagnetic plate 304 to control the movement of the push block 206 and the arc-shaped support plate 207. When the electromagnetic plate 304 generates a magnetic field, the second magnetic block 209 is attracted or repelled, prompting the push block 206 to move downward, thereby firmly fixing the electric wire 103 on the fixing groove 208, preparing for subsequent crimping and conductive agent injection. When operating in the reverse direction, the electromagnetic plate 304 generates a magnetic field in the opposite direction, causing the second magnetic block 209 to be repelled, driving the push block 206 to move upward, releasing the fixation of the electric wire 103. A support block 210 is fixedly connected between the two electric sliding rails 201 on the upper surface of the bottom plate 1. The lower surface of the cold-press terminal 102 abuts against the support block 210.

[0045] Further, place the wire 103 on the fixed groove 208, place the ends of the cold press terminal 102 on the two support blocks 210 respectively, start the electromagnet in the electromagnetic plate 304 to generate magnetism, prompt the first magnetic block 3034 and the second magnetic block 209 to generate opposite magnetism and attract each other, prompt the second 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 first telescopic rod 204 and the support spring 205 to move, so that the arc-shaped support plate 207 fixes the wire 103 on the fixed groove 208. At the same time, the electric slide rail 201 and the electric slider 202 continue to drive the arc-shaped clamping plate 203 to complete the crimping work of the cold press terminal 102 and the wire 103. After completing the work, start the electric slide rail 201 and the electric slider 202 to drive the arc-shaped clamping plate 203 away from the cold press terminal 102. At the same time, start the electromagnetic plate 304 to generate a same-sex magnetic field with the first magnetic block 3034 and the second magnetic block 209, prompting them to repel each other, so that the second magnetic block 209 drives the push block 206 and the arc-shaped support plate 207 to move upward through the mutual cooperation of the support spring 205 and the first telescopic rod 204, releasing the fixation of the wire 103.

[0046] Embodiment 2:

[0047] Refer to Figures 1-9 , which is the second embodiment of the present invention. Based on the previous embodiment, the conductive agent injection assembly 3 is installed inside the storage tank 104.

[0048] Specifically, the conductive agent injection assembly 3 includes two feeding pipes 301 fixedly installed on the lower surface of the storage tank 104. One end of the two feeding pipes 301 is fixedly connected with a conical pipe 302. A sealing plug 303 is clamped inside the feeding pipe 301. The sealing plug 303 is connected to a sealing ball 3031 through a connecting rod 305. When the sealing ball 3031 moves, it drives the sealing plug 303 to move together, thereby controlling the opening and closing of the feeding pipe 301. The bottom of the conical pipe 302 is fixedly connected with a discharge port 308. A sealing ball 3031 is clamped inside the discharge port 308. 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 first magnetic block 3034, it can open or close the discharge port 308, thereby controlling the injection of the conductive agent. On the contrary, when the sealing ball 3031 is in the closed state, it can prevent the conductive agent from being discharged from the discharge port 308.

[0049] A connecting rod 305 is fixedly connected between the sealing ball 3031 and the sealing plug 303. A rigid sealing sleeve 3032 is fixedly installed on the outer surfaces of the sealing plug 303 and the sealing ball 3031. A first magnet 3034 is fixedly installed in the inner cavity of the sealing ball 3031. The first magnet 3034 is magnetically connected to the electromagnetic plate 304. The first magnet 3034 refers to a permanent magnet installed in the sealing ball 3031 and is used to interact with the electromagnetic plate 304. When the electromagnetic plate 304 is energized and generates a magnetic field, the first magnet 3034 will be subjected to an attractive or repulsive force, thereby driving the movement of the sealing ball 3031 and the sealing plug 303, causing the first magnet 3034 to push the sealing ball 3031 downward to open the discharge port 308, enabling the conductive agent to smoothly flow into the gap between the cold pressing terminal 102 and the wire 103.

[0050] The storage tank 104, the conical tube 302 and the feeding tube 301 are filled with a conductive agent. The conductive agent is a substance that can significantly improve the electrical conductivity of materials. They are usually used to enhance the electrical 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 pressing terminal 102 and the wire 103, using the conductive agent can fill the possible tiny gaps, ensure the close contact between the conductor and the cold pressing terminal 102, reduce the contact resistance and improve the electrical conductivity.

[0051] A flexible sealing sleeve 3033 is fixedly connected to the outer surface of the rigid sealing sleeve 3032. The rigid sealing sleeve 3032 is made of a rigid sealing material, and the flexible sealing sleeve 3033 is made of a flexible sealing material. The rigid sealing sleeve 3032 is a sealing component made of a rigid sealing material and usually has high mechanical strength and wear resistance. It can withstand large pressure and temperature changes, ensuring that the sealing ball 3031 and the sealing plug 303 can maintain their shapes without deformation during long-term use, providing stable support and sealing effect. It can be replaced by metal materials, engineering plastics or ceramic materials. The flexible sealing sleeve 3033 has good elasticity and flexibility. The flexible sealing sleeve 3033 can provide additional elastic sealing on the basis of the rigid 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 the leakage of the conductive agent and ensuring the safety and efficiency of the operation. The flexible sealing sleeve 3033 can be replaced by rubber-like materials, elastomeric materials or composite materials.

[0052] There is a fixed connection between the sealing plug 303 and the storage box 104 with a second telescopic rod 306. A return spring 307 is sleeved and connected on the outer surface of the second telescopic rod 306. One end of the return 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 member 4 is installed on the outer surface of the conical tube 302. The trigger member 4 includes a plurality of connecting blocks 401 fixedly installed on the outer surface of the two conical tubes 302. An elastic airbag 402 is installed on the lower surface of the connecting block 401. The bottom of the elastic airbag 402 is fixedly connected to a spray gun 406. The elastic airbag 402 is a device that can deform when subjected to pressure and return to its original state after the pressure is released. It is usually 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 pressing terminal 102 and the wire 103, ensuring that the conductive agent is evenly distributed and improving the conductive performance. 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 connection gap. On the contrary, when the trigger block 407 moves away from the elastic airbag 402, the elastic airbag 402 will re-expand and inhale new gas for the next operation. The elastic airbag 402 can be replaced with polyurethane and fluororubber materials.

[0053] The trigger member 4 includes an elastic sleeve 404 fixedly installed on the outer surface of the elastic airbag 402. A plurality of trigger rods 403 are fixedly connected between the inner cavities of the elastic airbag 402. Both the trigger rods 403 and the elastic sleeve 404 are made of elastic materials. 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. Among them, the trigger rods 403 can be replaced with rubber, polyamide, and glass fiber reinforced plastic materials. The elastic sleeve 404 is used to protect the elastic airbag 402 and enhance its sealing performance to prevent gas leakage. Among them, the elastic sleeve 404 can be replaced with materials such as nitrile rubber and neoprene. The trigger member 4 also includes a trigger block 407 fixedly installed on the outer surface of the arc-shaped clamping plate 203. A silica gel pad 4071 is fixedly connected to the outer surface of the trigger block 407. The silica gel pad 4071 is mainly used to provide buffer protection and increase friction to ensure stable contact between the trigger block 407 and the elastic airbag 402. It can be replaced with materials such as polyurethane pads, neoprene pads, or nitrile rubber pads.

[0054] Further, the magnetic block 1 (3034) drives the sealing ball 3031 to move downward. When the sealing ball 3031 moves downward, it drives the sealing plug 303 to move downward through the connecting rod 305, so that the sealing plug 303 blocks the material conveying pipe 301. At the same time, the sealing ball 3031 opens the discharge port 308, so that the conductive agent in the material conveying pipe 301 and the conical pipe 302 is injected into the gap on the surface of the cold pressing terminal 102 through the discharge port 308. During the movement of the arc-shaped clamping plate 203, the touch block 407 and the silica gel pad 4071 above it squeeze the elastic air bag 402 and the elastic sleeve 404, so that the gas in the elastic air bag 402 is sprayed out through the two spray guns 406. The sprayed gases intersect with each other, guiding the injected conductive agent to fully enter the conductor through the gap, ensuring the uniform distribution of the conductive agent and improving the conductive performance. Then, the electromagnetic plate 304 and the magnetic block 1 (3034) generate a same-sex magnetic field, prompting them to repel each other. The magnetic block 1 (3034) drives the sealing ball 3031 to drive the sealing plug 303 to move upward through the connecting rod 305, and is reset through the telescopic rod 2 (306) and the return spring 307, so that the sealing plug 303 enters the storage box 104, and the sealing ball 3031 blocks the discharge port 308.

[0055] The working principle of the present invention: During use, use a wire stripper to strip the insulating layers at both ends of the wire 103 to expose the internal conductor, then insert it into the two cold pressing terminals 102, and then place the wire 103 on the fixing groove 208. The ends of the cold pressing terminals 102 are respectively placed on the two support blocks 210 to provide stable support for subsequent operations. Start the electromagnet in the electromagnetic plate 304 to generate magnetism, prompting the magnetic block 1 (3034) and the magnetic block 2 (209) to generate opposite-sex magnetism and attract each other, prompting the magnetic block 2 (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, so as to support the push block 206, so that the arc-shaped support plate 207 fixes the wire 103 on the fixing groove 208.

[0056] The magnetic block 1 (3034) drives the sealing ball 3031 to move downward. When the sealing ball 3031 moves downward, it drives the sealing plug 303 to move downward through the connecting rod 305, so that the sealing plug 303 blocks the material conveying pipe 301. At the same time, the sealing ball 3031 opens the discharge port 308, so that the conductive agent in the material conveying pipe 301 and the conical pipe 302 is injected into the gap on the surface of the cold pressing terminal 102 through the discharge port 308. During the movement of the arc-shaped clamping plate 203, the touch block 407 and the silica gel pad 4071 above it squeeze the elastic air bag 402 and the elastic sleeve 404, so that the gas in the elastic air bag 402 is sprayed out through the two spray guns 406. The sprayed gases intersect with each other, guiding the injected conductive agent to fully enter the conductor through the gap, ensuring the uniform distribution of the conductive agent and improving the conductive performance. Finally, the gas flows out from both ends of the cold pressing terminal 102.

[0057] Meanwhile, when the sealing plug 303 moves downward, it will drive the second telescopic rod 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-shaped clamping plate 203 to complete the crimping work of the cold pressing terminal 102 and the wire 103.

[0058] After the work is completed, start the electric slide rail 201 and the electric slider 202 to drive the arc-shaped clamping plate 203 away from the cold pressing terminal 102. At this time, the touch block 407 and the silica gel pad 4071 drive the elastic airbag 402 to reset through the mutual cooperation of the touch rod 403 and the elastic sleeve 404. At the same time, the gas enters the elastic airbag 402 through the spray gun 406, making the gas in the elastic airbag 402 sufficient. Then start the electromagnetic plate 304 to generate a same-sex magnetic field with the first magnetic block 3034 and the second magnetic block 209, prompting them to repel each other. Thus, the second magnetic block 209 drives the push block 206 and the arc-shaped support plate 207 to move upward through the mutual cooperation of the support spring 205 and the first telescopic rod 204, releasing the fixation of the wire 103. The first magnetic block 3034 drives the sealing ball 3031 to drive the sealing plug 303 to move upward through the connecting rod 305, and resets through the second telescopic rod 306 and the return 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, wait for the conductive agent to dry and take out the cold pressing terminal 102 and the wire 103, and prepare for the next round of crimping work of the cold pressing terminal 102 and the wire 103.
