Description

Technical Field

[0001] This utility model relates to the technical field of wire clamping mechanisms, and more specifically, to a wire clamping mechanism for a double-headed end-pressing and shell-penetrating soldering machine. Background Technology

[0002] The double-head crimping and tinning machine is an automated equipment used for electronic wire harness processing. It is mainly used in the 3C electronics industry. This equipment integrates wire cutting, wire stripping, crimping, shell insertion, terminal crimping pressure monitoring and terminal crimping shape CCD visual inspection. It also has functions such as end tinning and partial wire stripping. It can independently complete the automated production process from wire harness production to quality inspection.

[0003] In processes such as crimping, shell insertion, and tinning, it is necessary to ensure that the wires are in the correct position. If the wires cannot be fixed in the designated position, they are prone to displacement or shaking, which can lead to poor terminal crimping, inability to insert the shell, or deviation in the tinning position. To address this, a wire clamping mechanism for a double-head crimping, shell insertion, and tinning machine is provided. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a wire clamping mechanism for a double-headed end-pressing and shell-penetrating soldering machine, which aims to solve the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a wire clamping mechanism for a double-headed end-pressing and shell-penetrating soldering machine, including a support plate, wherein a clamping component is provided on the support plate; The clamping assembly includes two turntables mounted on a support plate, and each turntable has a rack on its outer side. The rack has a wire groove on its outer side for positioning the wire, and the two racks mesh with each other. One side of each of the two turntables is provided with an extension rod, and one end of each extension rod is hinged to a hinge rod. One end of each hinge rod is provided with an arc groove, and clamping plates are provided on both sides of the inner wall of the arc groove.

[0006] Optionally, in a possible implementation, a hinge frame is rotatably connected to the hinge rod, one end of the hinge frame extends to the support plate and is rotatably connected to the support plate, and the vertical cross-sectional shape of the arc groove and the clamping plate is set to arc shape, and the clamping plate is engaged with the arc groove. Optionally, in a possible implementation, the two turntables are arranged opposite to each other, and one of the turntables has a misalignment opening at its bottom, the misalignment opening being formed through the support plate, a rotating shaft being arranged inside the misalignment opening, the top end of the rotating shaft being fixed to the turntable at its top, a motor for driving the rotating shaft to rotate being arranged at the bottom of the support plate, and a mounting plate being bolted to one end of the support plate, the vertical cross-sectional shape of the mounting plate being L-shaped; The technical effects and advantages of this utility model are as follows: By precisely matching the wire diameter to the wire groove on the outer side of the rack, the wire is confined within the groove, preventing horizontal movement and achieving initial positioning. The reverse linkage of the two meshing racks drives the extension rod and hinge rod synchronously, ultimately causing the arc-shaped clamp within the groove to clamp the wire in a wrapping manner. The arc-shaped structure perfectly matches the cylindrical shape of the wire, increasing the contact area, dispersing the clamping force, and firmly fixing the wire radially. This ensures the wire remains in the designated position throughout the crimping, casing, and soldering processes, effectively preventing processing defects caused by wire misalignment and significantly improving the wire harness processing yield.

[0007] The interlocking structure of the arc-shaped clamp and the arc groove allows for the adaptation of electronic wire harnesses of different diameters by replacing clamps with different curvatures or sizes, without requiring significant modifications to the overall mechanism. This expands the applicability of the mechanism. The L-shaped mounting plate, which is bolted to one end of the support plate, can be directly and precisely connected to the body of the double-headed end-pressing and tinning machine. During installation, integration can be completed simply by fixing with bolts, without the need for additional adjustments to the machine body structure. This reduces the difficulty of adapting the mechanism to the whole machine and facilitates rapid assembly and modification of the production line. Attached Figure Description

[0014] 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.

[0015] This embodiment discloses a wire clamping mechanism for a double-head crimping, shell-penetrating, and tinning machine, which aims to solve the problem that in the prior art, when double-head crimping, shell-penetrating, and tinning machines perform crimping, shell-penetrating, and tinning processes on wires, the wires cannot be stably fixed in the designated position, and are prone to offset or shaking, which leads to poor terminal crimping, inability to insert the shell, or deviation in the tinning position.

[0016] Specifically, the wire clamping mechanism of the double-headed crimping and tinning machine includes a support plate 1. The support plate 1 serves as the mounting and support base for the entire clamping mechanism, providing a stable mounting platform for other components. A clamping assembly for clamping the wires is provided on the support plate 1; this clamping assembly is the core structure ensuring the stable fixing of the wires.

[0017] The clamping assembly includes two turntables 2 mounted on a support plate 1, positioned opposite each other. This relative arrangement provides the foundation for subsequent synchronous transmission and coordinated action. A rack 3 is mounted on the outer side of each turntable 2, and the rack 3 is fixedly connected to the turntable 2 to ensure that the turntable 2 rotates synchronously with the rack 3. A wire groove 4 is formed on the outer side of the rack 3 for positioning the wire. The size of the wire groove 4 is adapted to the diameter of the wire to be processed, confining the wire within the groove and initially positioning the wire to prevent horizontal displacement. Furthermore, the two racks 3 mesh. When one rack 3 rotates under the drive of the turntable 2, the meshing action drives the other rack 3 to rotate in the opposite direction, thereby moving the wire grooves 4 on the two racks 3 closer or further apart, providing power for clamping and releasing the wire.

[0018] Extension rods 5 are respectively provided on one side of the two turntables 2, so that when the turntables 2 rotate, the extension rods 5 can drive the extension rods 5 to make circular motion around the center of the turntables 2. One end of each extension rod 5 is hinged to a hinge rod 6, and a hinge frame 7 is rotatably connected to the hinge rod 6. One end of the hinge frame 7 extends to the support plate 1 and is rotatably connected to the support plate 1. The hinge frame 7 provides a rotation support point for the hinge rod 6 and limits the movement trajectory of the hinge rod 6. When the extension rod 5 moves in a circular motion with the turntables 2, it will push or pull the hinge rod 6, causing the hinge rod 6 to rotate around the connection point between the hinge frame 7 and the support plate 1. Each hinge rod 6 has an arc groove 8 at one end, and a clamping plate 9 is provided on both sides of the inner wall of the arc groove 8. The vertical cross-section of both the arc groove 8 and the clamping plate 9 is arc-shaped, and the clamping plate 9 is engaged with the arc groove 8. This arc-shaped structure design matches the cylindrical shape of the conductor, which can increase the contact area between the clamping plate 9 and the conductor, improve the clamping stability of the conductor, and avoid damage to the conductor insulation layer due to concentrated clamping force. When the hinge rod 6 rotates under the drive of the extension rod 5, it will drive the arc groove 8 and the clamping plate 9 to move synchronously, so that the clamping plates 9 on the two hinge rods 6 are relatively close, and finally achieve the clamping operation of the conductor; conversely, when the extension rod 5 moves in the opposite direction, the clamping plates 9 are relatively far apart, releasing the conductor.

[0019] One of the turntables 2 has a misalignment opening 12 at its bottom, which extends through the support plate 1. A rotating shaft 13 is installed within the misalignment opening 12, and the top end of the rotating shaft 13 is fixed to the turntable 2 on top of it. The rotating shaft 13 and the turntable 2 are connected by a key to ensure that the rotating shaft 13 can drive the turntable 2 to rotate synchronously when it rotates. A motor 10 for driving the rotating shaft 13 is installed at the bottom of the support plate 1. The motor 10 is bolted to a motor mounting base at the bottom of the support plate 1. The output shaft of the motor 10 is connected to the rotating shaft 13 by a coupling to ensure that the power of the motor 10 can be stably transmitted to the rotating shaft 13. The motor 10 serves as the power source for the entire clamping mechanism. By controlling the forward and reverse rotation of the motor 10, the rotating shaft 13 can be rotated in both directions, which in turn drives the connected turntable 2 to rotate in both directions. Through a series of transmission structures, the clamping and releasing actions of the clamping plate 9 on the wire are finally realized.

[0020] In addition, a mounting plate 11 is bolted to one end of the support plate 1. The vertical cross-section of the mounting plate 11 is set to L-shape. The L-shaped structure design allows the mounting plate 11 to be stably connected to the support plate 1 and to be easily installed and fixed to the body of the double-headed end-pressing and shell-piercing tinning machine. The entire wire clamping mechanism can be integrated into the double-headed end-pressing and shell-piercing tinning machine through the mounting plate 11, so as to achieve collaborative work with other processes of the whole machine.

[0021] The specific working principle is as follows: When clamping the wire is required, the motor 10 at the bottom of the support plate 1 is started. The motor 10 drives the connected rotating shaft 13 to rotate, and the rotating shaft 13 drives the top turntable 2 to rotate. Since the rack 3 on the outer side of the turntable 2 meshes with the rack 3 on the outer side of the other turntable 2, the rotation of the turntable 2 will drive the other turntable 2 to rotate in the opposite direction. When the two turntables 2 rotate, they will drive the extension rod 5 on their respective sides to make a circular motion. The extension rod 5 pushes the hinge rod 6 to rotate around the connection point between the hinge frame 7 and the support plate 1. As the hinge rod 6 rotates, the arc groove 8 and the clamping plate 9 at one end gradually approach the wire to be clamped until the clamping plate 9 on the two hinge rods 6 tightly clamps the wire. At this time, the motor 10 stops running, and the wire is stably fixed in the designated position for subsequent processes such as end pressing, shell penetration, and tinning.

[0022] When the wire needs to be released after completing the corresponding process, the control motor 10 reverses. The motor 10 drives the rotating shaft 13 and the connected turntable 2 to rotate in the opposite direction. Through the meshing action of the rack 3, it drives the other turntable 2 to rotate in the forward direction, which in turn drives the extension rod 5 to move in the opposite direction. The extension rod 5 pulls the hinge rod 6 to rotate in the opposite direction, so that the two clamping plates 9 move away from each other, releasing the wire. The worker can then take out the processed wire, completing one wire clamping process.

[0023] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
