Description

Technical Field

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

[0002] In the field of wire harness processing, three-plate wire clamps are widely used because they can neatly secure multi-strand wires. These clamps typically include a base plate, a first flap for clamping the wire, a second flap covering it, and a connecting rod linking the base plate and the second flap; the structure is relatively complex. Before pressing the wire into the clamp, the clamp must first be opened from its locked position.

[0003] Existing patent CN114379040B discloses a multi-station automatic low-pressure injection molding machine, including a wire clamp and a wire clamp opening mechanism. The wire clamp is a double-plate type. The wire clamp opening mechanism includes a gear and rack mechanism for driving the wire clamp to open, a wire clamp advance and retraction cylinder for actuating the drive, and a wire clamp loosening assembly for pre-loosening. The cylinder pushes the rack, causing the gear to rotate, thereby opening the wire clamp and automatically releasing the wire from the product after injection molding. However, this mechanism is functionally limited and simple in operation, only suitable for conventional double-plate wire clamps. Double-plate wire clamps lack sufficient clamping force and are prone to loosening. This mechanism cannot handle complex three-plate clamping structures.

[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 wire clamp opening mechanism. This utility model realizes the fully automatic and step-by-step conversion of the three-plate wire clamp from the closed to the fully open state, which is reliable and efficient.

[0006] This utility model achieves the above objective through the following technical solution: an automatic wire clamp opening mechanism for switching a wire clamp from a closed state to an open state, the wire clamp including a base plate, a first flap plate rotatably connected to one end of the base plate, and a second flap plate rotatably disposed at the other end of the base plate via a connecting rod and covering the first flap plate in the closed state; the automatic wire clamp opening mechanism includes: The wire clamp support platform is used to support and position the wire clamps. The first flip module is used to drive the second flip to the open state, and includes a driving component, a first support plate driven by the driving component to move in the X direction, a first push plate disposed on the first support plate for pushing the second flip and the connecting rod, a first cylinder disposed on the first support plate, and a second push plate driven by the first cylinder to push the second flip in the X direction. The second flip-top module is used to drive the first flip-top to the open state, and includes a second cylinder, a second support plate driven by the second cylinder to move along the Y-axis, a third cylinder disposed on the second support plate, and a clamping rod driven by the third cylinder to rotate around the Y-axis and clamp open the first flip-top.

[0007] Furthermore, it also includes a support module disposed at one end of the connecting rod and used to support the connecting rod.

[0008] Furthermore, the clamp carrying platform is provided with a pair of limiting plates for restricting the movement of the clamp along the Y direction.

[0009] Furthermore, the support module includes a fourth cylinder and a third push plate that is driven by the fourth cylinder to support the connecting rod in the opposite direction along the X direction.

[0010] Furthermore, the second push plate is disposed on the first push plate or on the first support plate.

[0011] Furthermore, the height of the first push plate and the second push plate is higher than that of the third push plate.

[0012] Furthermore, the second flip module also includes a stop bar for limiting the rotation range of the clamping rod.

[0013] Furthermore, the first flap is provided with a clamping groove at the end near the connecting rod corresponding to the clamping rod position, allowing the clamping rod to extend into it.

[0014] Furthermore, the upper surface of the base plate of the wire clamp is provided with several wire grooves for accommodating wires.

[0015] Compared with the prior art, the beneficial effects of the automatic wire clamp opening mechanism of this utility model are as follows: (1) Optimized workflow, smooth process connection, and strong system reliability: The complex wire clamp opening action is decomposed into multiple orderly processes such as support and fixation → opening the second flap → rotating and opening the first flap. Each module can be reset in time after completing the current process, making room for the operation of subsequent modules and avoiding motion interference. The entire process design has a clear logic and tight process connection, which not only ensures the smoothness of the wire clamp opening process, but also greatly improves the stability and reliability of continuous operation of the equipment and reduces the failure rate.

[0016] (2) The mechanism is ingeniously designed, with reliable positioning and effective protection for the wire clamp: The wire clamp platform adopts a double fixing structure consisting of a fixing block and a magnetic block, which ensures the stable positioning of the wire clamp during processing. The first flip-top module uses the first push plate to realize the gradual opening of the second flip-top, with smooth operation; the support module provides precise support and limit to the connecting rod during the ejection process through the third ejection plate, preventing the overall displacement of the wire clamp. The second flip-top module uses the clamping rod and the clamping groove on the first flip-top to achieve reliable clamping and rotation opening, with minimal mechanical interference throughout the process, effectively avoiding structural damage to the precision wire clamp.

Detailed Implementation

[0018] The present invention will be further described in detail below with reference to specific embodiments.

[0019] Example: Please refer to Figures 1 to 6This embodiment provides an automatic wire clamp opening mechanism 100 for switching a wire clamp 200 from a closed state to an open state. The wire 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 wire clamp opening mechanism 100 includes a wire clamp supporting platform 1 for supporting and positioning the wire clamp 200, a first flip-cover module 2 for driving the second flap 203 to the open state, a second flip-cover module 3 for driving the first flap 202 to the open state, and a support module 4 disposed at one end of the connecting rod 204 of the wire clamp 200 and for supporting the wire clamp 200 when the second flap 203 is opened.

[0020] In this embodiment, the wire clamp 200 includes three states: closed state, intermediate state, and open state. The closed state is the initial state, characterized by the first flap 202 being fastened to the base plate 201 and the second flap 203 being fastened to the first flap 202. The first intermediate state is characterized by the second flap 203 opening upward relative to the first flap 202, and the first flap 202 being fastened to the base plate 201. The second intermediate state is characterized by the second flap 203 opening towards one end of the connecting rod 204 and extending towards the free end, and the first flap 202 being fastened to the base plate 201. The open state is the target state, characterized by the second flap 203 opening towards one end of the connecting rod 204 and extending towards the free end, and the first flap 202 opening towards the other end and extending towards the free end.

[0021] The first flip module 2 includes a driving member 21, a first support plate 22 driven by the driving member 21 to move in the X direction, a first push plate 23 disposed on the first support plate 22 for pushing the second flip 203 and the connecting rod 204, a first cylinder 24 disposed on the first support plate 22, and a second push plate 25 driven by the first cylinder 24 to push the second flip 203 a second time in the X direction. The first support plate 22 is driven by the driving member 21 to move in the X direction, so that the first push plate 23 enters between the second flip 203 and the first flip 202. On the one hand, the first push plate 23 can open the second flip 203 upward relative to the first flip 202, and on the other hand, the first push plate 23 can push the connecting rod 204 in the X direction; at the same time, the second push plate 25 pushes in the X direction to make the second flip 203 fully open.

[0022] In this embodiment, the second push plate 25 is disposed on the first push plate 23, enabling it to move along the X direction following the drive of the first push plate 23 by the drive member 21. In other embodiments, the second push plate 25 may also be disposed on the first support plate 22. Furthermore, since the first push plate 23 is located at the height of the opening between the first flip plate 202 and the second flip plate 203, when the first push plate 23 pushes the second flip plate 203 along the X direction, without the second push plate 25, the first push plate 23 may cause the wire clamp 200 to behave as follows: Figure 5 The condition shown prevents the wire clamp 200 from opening fully, making subsequent operations impossible.

[0023] The clamp support platform 1 has a pair of limiting blocks 11 on both sides along the Y direction for positioning the clamp 200. The upper surface of the clamp support platform 1 is also provided with a magnetic fixing 12 for further limiting the clamp 200. The lower surface of the clamp 200 is correspondingly provided with a magnetic block (not shown in the figure). The limiting blocks 11 limit the clamp 200 on both sides along the Y direction, and the magnetic fixing 12 attracts the magnetic block on the clamp 200 to ensure the stable position of the clamp 200 on the clamp support platform 1. This provides an important foundation for the first flip module 2 and the second flip module 3 to open the clamp 200 stably, effectively and reliably.

[0024] The second flip-top module 3 includes a second cylinder 31, a second support plate 32 driven by the second cylinder 31 to move along the Y-axis, a third cylinder 33 disposed on the second support plate 32, and a clamping rod 34 driven by the third cylinder 33 to rotate around the Y-axis and clamp open the first flip-top 202. Furthermore, to enable the first flip-top 202 to open at a preset angle, a stop bar 35 is provided at the end of the rotation path of the clamping rod 34. A clamping groove 2021 is correspondingly provided on the bottom plate 201 near the connecting rod, and the clamping rod 24 can extend into the clamping groove 2021, allowing the clamping rod 24 to clamp the clamping groove 2021, thereby rotating around the Y-axis to open the first flip-top 202.

[0025] The support module 4 is used to position one end of the connecting rod of the wire clamp 200. When the first flip-top module 2 pushes open the second flip plate 203, it prevents the wire clamp 200 from shifting along the X-axis, ensuring the smooth opening of the second flip plate 203. Furthermore, the outer side of the connecting rod 204 provides positional limitation, allowing the second flip plate 203 to rotate relative to the pivot at the end of the connecting rod 204 when the second push plate 25 continues to push it, thus enabling a quick switch to the open state. If the outer side of the connecting rod 204 is not blocked, when the second push plate 25 pushes the second flip plate 203, the connecting rod 204 will rotate outward around the pivot at the end connected to the base plate 201, but the second flip plate 203 will rotate synchronously with the connecting rod 204 at an acute angle, preventing the second flip plate 203 from fully opening relative to the connecting rod 204. This could also cause the wire clamp 200 to appear as if... Figure 5 The state shown. The support module 4 includes a fourth cylinder 41 and a third push plate 42 that is driven by the fourth cylinder 41 to support the connecting rod 204 in the reverse direction along the X direction.

[0026] In summary, the working process of the automatic wire clamp opening mechanism 100 is as follows: First, the wire clamp 200 in the closed state is placed on the wire clamp support platform 1. The fourth cylinder 41 drives the third push plate 42 to move in the opposite direction of X to support one end of the wire clamp 204 connecting rod. The first push plate 23 pushes open the second flap 203 in the X direction, at which point the wire clamp 200 is in the first intermediate state. Then, the second push plate 25 fully opens the second flap 203 in the X direction, and the first flip cover module 2 resets. At this time, the wire clamp 200 is in the second intermediate state. Subsequently, the clamping rod 24 extends into the clamping groove 2021 and rotates around the Y axis to open the first flap 202. At this time, the wire clamp 200 is fully opened and is in the open state.

[0027] 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.
