Description

Technical Field

[0001] This utility model relates to the field of wire harness processing equipment technology, and in particular to an automatic wire clamping mechanism. Background Technology

[0002] In the field of automated wire harness processing, three-plate wire clamps are widely used to neatly fix multi-strand wires. These wire clamps typically contain complex components such as a base plate, a first flap, a second flap, and a connecting rod. Their fastening process requires several delicate steps, including pressing the wire with the first flap and finally locking it with the second flap.

[0003] Currently, existing technologies, such as the closing mechanism disclosed in patent CN115472345A, achieve automated fastening of simple two-plate wire clamps (containing only an upper and lower cover) through the cooperation of a flip-top assembly and a pressing assembly. However, this mechanism has relatively limited functionality; its flipping drive and pressing action are only suitable for wire clamps with simple structures and cannot handle complex three-plate wire clamps with intermediate flip plates and linkage structures. Specifically, it lacks the ability to accurately position multiple degrees of freedom of the wire clamp during the fastening process and does not design a step-by-step, orderly fastening process. If forcibly applied to three-plate wire clamps, it is very likely to cause problems such as fastening failure, wire clamp damage, or insecure wire clamping.

[0004] Therefore, it is necessary to design a new utility model to solve the above-mentioned technical problems. Utility Model Content

[0005] The main purpose of this utility model is to provide an automatic clamping mechanism. This utility model realizes the automatic clamping operation of the three-plate clamp through the coordinated operation of lifting, transferring and step-by-step fastening. It has the advantages of accurate positioning, reliable operation and high efficiency.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: an automatic wire clamp closing mechanism for switching a wire clamp from an open state to a closed state, the wire clamp comprising a base plate, a first flap rotatably connected to one end of the base plate, and a second flap rotatably disposed at the other end of the base plate via a connecting rod and covering the first flap in the closed state, comprising: A wire clamp positioning platform is used to support and position wire clamps. The first fastening module is used to drive the first flap to the closed state, and includes a first driving member and a first push plate driven by the first driving member to push the first flap along the Y direction; The second fastening module is used to drive the second flap to the closed state. It includes a second driving member, a first support plate driven by the second driving member to move in the opposite direction of Y, a second push plate fixed on the first support plate and used to push the connecting rod, a first cylinder fixed on the first support plate, and a third push plate driven by the first cylinder to move in the opposite direction of Y and push the second flap.

[0007] Furthermore, the cable clamp positioning platform is equipped with cable management plates on both sides for neatly combing the cables.

[0008] Furthermore, the wire clamp positioning platform is provided with a positioning protrusion for positioning the wire clamp in the Y direction; the base plate of the wire clamp is provided with a positioning groove at a corresponding position, into which the positioning protrusion can extend.

[0009] Furthermore, the wire clamp positioning platform is also provided with a magnetic fixing for further securing the wire clamp; a magnetic block is provided at the bottom of the wire clamp.

[0010] Furthermore, it also includes a second cylinder that drives the clamp positioning platform to move up and down.

[0011] Furthermore, the clamp positioning platform is disposed on the first support plate or at the movable end of the first drive member.

[0012] Compared with the prior art, the beneficial effects of the automatic wire clamp mechanism of this utility model are as follows: (1) Precise and reliable positioning, stable clamping: The positioning protrusion on the positioning platform of the wire clamp cooperates with the positioning groove on the bottom plate of the wire clamp to achieve precise positioning in the Y direction; combined with the magnetic fixation and the adsorption effect of the magnetic block, as well as the clamping of the wire clamp on both sides of the X direction by the wire organizing block, a multi-dimensional limiting mechanism is formed, which effectively prevents the wire clamp from shifting during the fastening process and ensures the stability and precision of the closing action. (2) Effective protection of the wire and clamp surfaces to avoid scratches: The ends of the first, second and third push plates are all arc-shaped and fitted with rollers, so that the contact between them and the clamp flip plate and connecting rod is changed from sliding friction to rolling friction. This design efficiently transmits the thrust while minimizing wear or scratches on the wire and clamp surfaces during the fastening process; (3) High degree of automation, smooth process and high efficiency: Through the sequential cooperation of the wire clamp positioning module, the first fastening module and the second fastening module, a fully automated process is realized from wire clamp loading and positioning, first flip plate fastening to the final closing of the second flip plate. The driving components of each module work together and the actions are continuous, integrating the complex operations that originally required manual step-by-step completion into a highly efficient automatic cycle, which significantly improves assembly efficiency and consistency.

Detailed Implementation

[0014] The present invention will be further described in detail below with reference to specific embodiments.

[0015] Example: Please refer to Figures 1 to 5 This embodiment provides an automatic cable clamp mechanism 100 and a cable clamp 200. The cable clamp 200 includes a base plate 201, a first flap 202 rotatably connected to one end of the base plate 201, and a second flap 203 rotatably disposed at the other end of the base plate 201 via a connecting rod 204 and covering the first flap 202 in the closed state. The automatic cable clamp mechanism 100 includes a cable clamp positioning module 1 for supporting and positioning the cable clamp 200, a first fastening module 2 for driving the first flap 202 to the closed state, and a second fastening module 3 for driving the second flap 203 to the closed state. The first fastening module 2 and the second fastening module 3 are arranged sequentially along the Y direction.

[0016] In this embodiment, the wire clamp 200 has a three-plate structure, which includes three states: open state, intermediate state, and closed state. The open state is the initial state, in which the first flap 202 extends from one end of the base plate 201 toward the free end, and the second flap 203 extends from the other end of the base plate 201 toward the free end. The intermediate state is in which the first flap 202 is fastened to the base plate 201, and the second flap 203 extends toward the free end. The closed state is the final state, in which the first flap 202 is fastened to the base plate 201, and the second flap 203 is fastened to the first flap 202.

[0017] The first fastening module 2 is used to switch the wire clamp 200 from the open state to the intermediate state, and includes a first driving member 21 and a first pressing plate 22 that is pushed by the first driving member 21 along the Y direction to the first flip plate 202.

[0018] The second fastening module 3 is used to switch the wire clamp 200 from the intermediate state to the closed state, and includes a second driving member 31, a first support plate 32 that is driven by the second driving member 31 to move in the opposite direction along the Y axis, a second push plate 33 that is fixed on the first support plate 32 and is used to push the connecting rod 204, a first cylinder 34 that is fixed on the first support plate 32, and a third push plate 35 that is driven by the first cylinder 34 to move in the opposite direction along the Y axis and is used to push the second flip plate 203.

[0019] The wire clamp positioning module 1 includes a third driving member 11, a second support plate 12 driven by the third driving member 11 to move along the Y direction, a second cylinder 13 disposed on the second support plate 12, and a wire clamp positioning platform 14 moved up and down by the second cylinder 13. The first driving member 21 is disposed on the wire clamp positioning platform 14.

[0020] In this embodiment, the wire clamp positioning platform 14 is disposed on the second support plate. In other embodiments, the wire clamp positioning platform 14 may also be disposed at any position within the range where the first fastening module 2 and the second fastening module 3 can perform the closing operation, for example, disposed on the first support plate 32 or directly disposed at the movable end of the first driving member 21.

[0021] To ensure the wire clamp 200 can smoothly switch from the open state to the closed state, it is necessary to prevent the wire clamp 200 from shifting in the X and Y directions during the switching process. Therefore, wire clamp positioning platform 14 has wire organizing blocks 141 on both sides in the X direction. The wire organizing blocks 141 can clamp the wire clamp 200 on both sides in the X direction to prevent it from shifting in the X direction. On the other hand, the wire organizing blocks 141 have several wire organizing grooves 1411 for accommodating wires, so the wire organizing blocks 141 can also sort and avoid wires passing through them. In addition, the wire clamp positioning platform 14 is also provided with positioning protrusions 142 for positioning the wire clamp 200 in the Y direction and magnetic fixing 143 for further defining the wire clamp 200. The base plate 201 is provided with positioning grooves 2011 that allow the positioning protrusions 142 to extend into and are sized to fit the positioning protrusions, and magnetic blocks (not shown in the figure) that cooperate with the magnetic fixing 143.

[0022] To protect the wire and clamp surfaces from wear during the fastening process, this embodiment designs the ends of the first push plate 22, the second push plate 33, and the third push plate 35 as arc-shaped structures, with rollers embedded in the center of the arc surface. This design changes the contact between the ejector plate and the clamp from sliding friction to rolling friction, thereby effectively transmitting thrust while minimizing scratches.

[0023] The working process of the automatic wire clamp mechanism 100 is as follows: Loading and positioning: Place the wire clamp 200 in the open state on the wire clamp positioning platform 14, and position and fix it in the Y direction through the positioning protrusion 142 and the magnetic fixation 143. The wire organizing blocks 141 on both sides restrict its X-direction displacement. Engaging the first flap: The first driving member 21 pushes the first pressing plate 22 to move along the Y direction, so that the roller at its end presses the first flap 202, driving the wire clamp from the open state to the middle state; Engaging the second flap: The second driving component 31 drives the first support plate 32 to move in the opposite direction of the Y-axis. The second push plate 33 fixed on it pushes the connecting rod 204, while the first cylinder 34 drives the third push plate 35 to press against the second flap 203. The two work together to engage the second flap 203 onto the first flap 202, so that the wire clamp reaches the closed state; Mechanism reset: Each driving component moves the push plate and support plate back to their initial positions, allowing the closed wire clamp to be removed and ready for the next work cycle.

[0024] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
