Description

Technical Field

[0001] This utility model relates to the field of terminal crimping technology, specifically a crimping mechanism for electronic component processing. Background Technology

[0002] In electronic component manufacturing, terminals are typically crimped to the ends of wire-type components for subsequent connection. Terminal crimping machines are commonly used for this process. By applying pressure, the terminal crimping machine creates a tight electrical connection between the terminal and the wire / cable. This connection method offers advantages such as fast connection speed, high connection quality, and ease of operation. Currently, there are various types of terminal crimping machines available to suit different production scales. For small-scale production, scissor-type crimping machines are commonly used.

[0003] During the operation of existing scissor-type crimping machines, the terminals deform under pressure. The deformed terminals adhere to the inner wall of the crimping groove, which can easily cause the terminals to get stuck in the crimping groove, making it difficult to remove them and thus affecting production efficiency.

[0004] Therefore, it is necessary to propose a wire pressing mechanism for electronic component processing to solve the above problems. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Please see Figure 1-6 As shown, a wire crimping mechanism for electronic component processing includes a frame 1. A fixed blade 4 is fixedly connected to one side of the frame 1. A movable blade 2, driven to rotate by a drive mechanism, is located above the fixed blade 4. A terminal limiting groove 5 and a crimping groove 6 are formed on the side of the fixed blade 4 near the movable blade 2. A pressing block 3 is provided at the position of the movable blade 2 corresponding to the crimping groove 6. During terminal crimping, the wire is placed in the crimping groove 6, the terminal is limited by the terminal limiting groove 5, and its wiring part is placed in the crimping groove 6. The movable blade 2 is driven to rotate by the drive mechanism, and the crimping block 3 performs the terminal crimping.

[0029] A limiting groove 7 is provided between the terminal limiting groove 5 and the crimping groove 6. A movable plate 12 is slidably connected in the limiting groove 7. A cut 14 adapted to the terminal limiting groove 5 is provided on the upper part of the movable plate 12. A material ejection slope 13 is provided on one side of the terminal limiting groove 5. A lever 10 is rotatably connected to one end of the moving blade 2 near its rotation axis. A return torsion spring is provided at the rotatable connection between the lever 10 and the moving blade 2. The lever 10 rotates with the moving blade 2 to push the movable plate 12 to slide along the limiting groove 7. A return spring 15 is provided at the end of the limiting groove 7 away from the lever 10.

[0030] Specifically, a limiting block 9 is fixedly connected to one side of the push block 10. The limiting block 9 is used to limit the rotation angle of the push block 10 to support the push block 10 and make it push the movable plate 12 to slide. The material ejection inclined surface 13 is located on the side of the cut 14 near the push block 10.

[0031] By placing the movable plate 12 between the limiting groove 5 and the crimping groove 6, it avoids affecting the crimping of the terminal while bringing it close to the crimping part of the terminal. The terminal structure here has high strength, which can prevent the terminal from deforming when it is ejected.

[0032] Please see Figure 2-3As shown, after the terminal crimping is performed, when the moving blade 2 rotates to reset, the moving blade 2 drives the toggle block 10 to rotate. The toggle block 10 acts on the end of the movable plate 12, pushing the movable plate 12 to move towards the front end of the fixed blade 4. During the movement, the ejection slope 13 moves to the space between the terminal limiting groove 5 and the crimping groove 6, pushing out the crimped terminal. When the moving blade 2 rotates to the limit position, the toggle block 10 passes over the movable plate 12 and rotates to the top of the movable plate 12. Under the action of the movable plate 12, it pushes the movable plate 12 to reset.

[0033] Please see Figure 4-5 As shown, during the pressing process, when the moving knife 2 rotates downward, the push block 10 contacts the upper end face of the movable plate 12, the push block 10 is forced to rotate upward, and the reset torsion spring is compressed. When the distance between the rotation axis of the push block 10 and the movable plate 12 is greater than the length of the push block 10, the push block 10 passes over the movable plate 12 and is reset under the action of the reset torsion spring.

[0034] A stop block 11 is fixedly connected to the inner side of the end of the limiting groove 7 away from the return spring 15. By setting the stop block 11, the movable plate 12 is limited, so that with the cooperation of the return spring 15, the cut 14 of the movable plate 12 is aligned with the terminal limiting groove 5 after reset.

[0035] Please see Figure 6 As shown, in order to prevent the movable plate 12 from sliding out of the limiting groove 7, the limiting groove 7 has strip grooves 17 on both sides inside, and the movable plate 12 is fixedly connected to the strip grooves 17 at the corresponding positions on both sides.

[0036] With the cooperation of slider 16 and strip groove 17, the movable plate 12 is limited to prevent it from sliding out of the limiting groove 7, and at the same time, the reciprocating sliding of the movable plate 12 is more stable.

[0037] In some embodiments, there are multiple crimping grooves 6, and the multiple crimping grooves 6 have different sizes. By providing multiple crimping grooves 6 of different sizes, it can be adapted to crimping terminals of different sizes.

[0038] In some embodiments, one end of the moving blade 2 is fixedly connected to a rotating shaft 8, the rotating shaft 8 is rotatably connected to the frame 1 through a bearing, and the rotating shaft 8 is driven to rotate by a geared motor.

[0039] 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.
