Description

Technical Field

[0001] This utility model relates to the field of terminal pressing technology, specifically a mold pressing terminal mechanism. Background Technology

[0002] Terminal crimping dies are specialized tools used to fix electrical terminals to wires or cables. They typically consist of an upper die and a lower die. They use pressure to deform and fasten the metal terminals to the conductor, forming a reliable electrical connection. They are characterized by high precision, durability, and versatility.

[0003] In existing molds, terminal crimping is mostly done manually, which involves workers performing a lot of repetitive mechanical labor, wasting manpower and potentially causing occupational diseases, while also affecting work, resulting in low production efficiency. Furthermore, wire cutting relies on manual cutting with tools, and it is difficult for workers to ensure that the stripped and cut lengths are consistent, thus affecting the quality of the finished product.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example:

[0028] Please see Figures 1 to 4 This utility model provides a technical solution:

[0029] A mold pressing terminal mechanism, comprising:

[0030] The terminal pressing mold frame 16 has a connecting rod 5 fixedly installed at its rear end. The connecting rod 5 extends to the right and is rotatably connected to a reel fixing shaft 4 at its top end. A reel 6 is rotatably connected to the reel fixing shaft 4. The reel 6 contains a material strip 3. The terminal pressing mold also has a flux wetting device 26 and a terminal pressing product receiving box 27.

[0031] The wire placement rack 15 is installed on the left side of the terminal pressing mold frame 16. The upper end of the wire placement rack 15 has a container for holding wires. The center of the container has a protruding column 14. The top of the column 14 is fixedly connected to an L-shaped column 1401. A first robotic arm 10 is slidably connected to the L-shaped column 1401.

[0032] In this embodiment, the terminal pressing mold frame 16 is connected to the terminal pressing parameter adjustment computer 12, which sets the required parameters to make the terminal pressing conform to the usage specifications.

[0033] The first robotic arm 10 grips the wire and enters the second stripping blade 902 of the mold stripping step structure 9 from the rear. The computer 12 adjusts the parameters set according to the terminal pressing parameters to cut the gripped wire. The cut wire will fall into the storage box 21 for storage. Then, the first robotic arm 10 grips the front end of the cut wire and moves it to the waterproof plug insertion step structure 8.

[0034] The first robotic arm 10 clamps the end of the wire and inserts it into the waterproof plug mold to the corresponding depth according to the set requirements. The waterproof plugs in the insertion step structure 8 are arranged in the channel 17 by the operation of the vibratory plate 2. The pneumatic sensor 18 installed at the front end of the channel 17 can sense the waterproof plugs and push them through the transmission pipe 19 to the waterproof plug insertion step structure 8 by blowing air. The plugs are then clamped by the cylinder 20. When the cylinder 20 receives the wire insertion depth and finds it is correct, it can release the waterproof plug.

[0035] After the waterproof plug is inserted, the terminal needs to be crimped. This step also requires stripping the wire. The first robot arm 10 transports the wire with the waterproof plug inserted to the first stripping knife 901 of the mold stripping step structure 9 to strip the front end of the wire. After stripping, the first robot arm 10 transports the wire to the terminal mold riveting structure 7 for riveting.

[0036] In this embodiment, after the motor at the bottom of the vibratory feeder 2 is started, the waterproof plug is transported through the vibratory feeder 2 to the channel 17 and arranged to be delivered to the waterproof plug insertion step structure 8 to wait for the wire to be inserted, which improves the feeding efficiency.

[0037] In this embodiment, the second robotic arm 22 grips the wire and moves it to the flux wetting device 26 via a screw to wet the stripped part of the wire with flux. After the flux wetting process is completed, the third robotic arm 23 transports the stripped wire to the solder pot 11, and then the fifth robotic arm 25 immerses the wire in the solder pot 11 for the tin-immersion process. This can improve the conductivity of the wire, and because the melting point of the tin layer is low, it is easy to remelt and form a connection. If it is necessary to replace or repair the wire, the tin-immersed terminal is easier to solder or crimp with the new wire.

[0038] Once the tinning process is complete, the fourth robotic arm 24 can be used to pick up the wires and transport them to the terminal crimping product receiving box 27 for placement.

[0039] Specifically, the terminal pressing structure includes a terminal mold riveting structure 7, a waterproof plug insertion step structure 8, and a mold peeling step structure 9.

[0040] In this embodiment, the terminals need to be pressed continuously. If the terminals are manually fed, the efficiency is relatively low. Therefore, the material strip 3 is used for feeding, and the material strip 3 is installed on the reel 6. The reel 6 can feed the terminals automatically and continuously by rotating, which greatly improves the work efficiency.

[0041] Specifically, one end of the material strip 3 is wound around the reel 6, and the other end is connected to the terminal mold riveting structure 7 for pressing with the stripped wire.

[0042] Specifically, the front end of the waterproof plug insertion step structure 8 is connected to the vibratory plate 2 through the channel 17, the pneumatic sensing device 18 and the conveying pipe 19, which is used to transport waterproof plug material to the waterproof plug insertion step structure 8. The waterproof plug insertion step structure 8 has a cylinder 20, and the bottom of the vibratory plate 2 has a mounting bracket 1.

[0043] Specifically, a terminal pressing parameter adjustment computer 12 is fixedly installed on the left side of the terminal pressing mold frame 16 via a bracket 13.

[0044] Specifically, the upper surface of the wire rack 15 has a container for holding wires.

[0045] Specifically, the extended end of the L-shaped column 1401 is horizontally parallel to the terminal pressing mold frame 16, and is used by the first robot arm 10 to grip the wire and perform various operations.

[0046] Specifically, the left side of the terminal pressing mold frame 16 is fixedly installed with a wire placement rack 15 and a terminal pressing parameter adjustment computer 12, and the right side is fixedly installed with a vibratory feeder 2 and a reel 6.

[0047] Specifically, the front end of the mold peeling step structure 9 has a storage box 21.

[0048] Specifically, a second robotic arm 22, a third robotic arm 23, a fourth robotic arm 24, and a fifth robotic arm 25 are also installed above the terminal pressing mold frame 16 via screws for transporting wires to various parts.

[0049] In use, this utility model first adjusts the terminal pressing parameters by setting the required parameters on the computer 12. Then, the first robotic arm 10 is started. Guided by the L-shaped column 1401, the first robotic arm 10 transports the end of the wire to be processed to the back entrance of the mold stripping step structure 9. The wire is cut by the second stripping knife 902. The first robotic arm 10 holds the cut end of the wire and transports it to the waterproof plug insertion step structure 8. At the same time, the waterproof plug is arranged in the channel 17 by the vibrating plate 2. The pneumatic sensor 18 installed at the front end of the channel 17 can sense the air blowing and push the waterproof plug through the transmission pipe 19 into the waterproof plug insertion step structure 8, where it is clamped by the cylinder 20. The first robotic arm 10 holds the end of the wire and inserts the wire into the waterproof plug mold to the corresponding depth according to the set required parameters. When the cylinder 20 receives the wire insertion depth, the waterproof plug can be released.

[0050] After the waterproof plug is inserted, the first robotic arm 10 clamps the front end of the wire and moves it to the first stripping knife 901 to strip the wire. After stripping, the first robotic arm 10 clamps the wire and transports it to the terminal mold riveting structure 7 for riveting, thus completing the terminal crimping of the wire.

[0051] After the crimping is completed, the first robot 10 clamps the wire to the second stripping knife 902 of the mold stripping step structure 9 and pushes the wire to be cut according to the set requirements. The second robot 22 clamps the cut wire and moves it to the third stripping knife 903 of the mold stripping step structure 9 through the screw to strip the wire tail. Then, the second robot 22 clamps the wire and moves it to the flux wetting device 26 through the screw to wet the stripped part of the wire with flux. After the flux wetting process is completed, the third robot 23 transports the stripped wire to the solder pot 11. Then, the fifth robot 25 immerses the wire in the solder pot 11 for the tinning process. After the tinning is completed, the fourth robot 24 clamps the wire and transports it to the terminal crimped product receiving box 27 for placement.

[0052] Finally, the wires are manually bundled and placed on the machine rack.

[0053] All other parts of this utility model not described herein are the same as existing technologies, or are known technologies, or can be implemented using existing technologies, and will not be described in detail here.

[0054] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
