Description

Technical Field

[0001] This utility model belongs to the field of wire bending processing, and specifically relates to a wire pushing mechanism. Background Technology

[0002] J-shaped guidewires are widely used medical devices in the medical field. Their most distinctive feature is the J-shaped bend at the tip, a unique design that provides better maneuverability and adaptability during operation. In traditional J-shaped guidewire manufacturing, the bending of the tip is often done manually, which is inefficient, costly, and results in inconsistent product quality.

[0003] To address this problem, a prior patent provides a guide wire bending device (application number CN202120325668.9). The device comprises a head fixing mechanism for fixing the guide wire tip, a pulling mechanism for fixing the guide wire and cooperating with the head fixing mechanism to tighten the guide wire, and a bending mechanism for bending the guide wire tip. The pulling mechanism has a pulling fixing position for fixing the guide wire, the head fixing mechanism has a head fixing position for fixing the guide wire tip, and the bending mechanism has a bending position for abutting against the guide wire to cooperate with the pulling mechanism and the head fixing mechanism to bend the guide wire tip. The shape formed by the head fixing position, bending position, and pulling fixing position is triangular. This prior patent provides a guide wire bending device that can automatically bend the guide wire tip, significantly improving efficiency and reducing labor costs compared to traditional manual bending operations.

[0004] However, when this type of guide wire elbow device is in operation, the guide wire pushing process is still manually operated: the guide wire is manually pushed so that the guide wire head passes through the trumpet-shaped expansion member and enters the guide channel between the upper and lower guide clamps, and continues to bypass the "U"-shaped groove on the rotating shaft and enter the clamping groove of the lower clamp on the head. This pushing method has the following drawbacks: 1. It requires manual operation, which not only increases labor costs but also affects the overall processing efficiency; 2. For manual pushing, it is impossible to guarantee the accuracy of the pushing distance and position each time, affecting the stability of the yield rate of the guide wire elbow. Utility Model Content

[0005] To address the aforementioned problems, the present invention aims to provide a wire pushing mechanism that can stably and automatically push the wire, thereby improving processing efficiency, reducing labor costs, and ensuring the stability of the yield rate during wire processing.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows.

[0007] A guide wire pushing mechanism, comprising:

[0008] Support structure;

[0009] A pusher block, which is movably mounted on the support body;

[0010] A pusher drive assembly for driving the pusher block to move repeatedly, wherein the pusher drive assembly is driven to connect with the pusher block;

[0011] A pusher clamping assembly for holding the guide wire, the pusher clamping assembly being disposed on the pusher block.

[0012] In this guide wire pushing mechanism, the guide wire is clamped by a pusher clamping component, and then the pusher block is driven to move on the support body by a pusher driving component, which in turn drives the pusher clamping component that clamps the guide wire to move, so as to automatically push the guide wire. This automatic guide wire pushing method not only improves processing efficiency and reduces labor costs, but also ensures the stability of the yield rate during guide wire processing.

[0013] Furthermore, the material pushing drive assembly includes a material pushing drive motor and a material pushing screw. The material pushing drive motor is fixedly mounted on the support body, and the material pushing drive motor is drivenly connected to the material pushing block through the material pushing screw.

[0014] Furthermore, the pusher block is movably mounted on the support body via a guide rail.

[0015] Furthermore, the pusher block includes a sliding part and a clamping part. The clamping part is fixedly disposed on one side of the sliding part, the sliding part is movably disposed on the support body, and the pusher drive assembly is drivenly connected to the sliding part. The pusher clamping assembly is fixedly disposed on the clamping part.

[0016] Furthermore, the clamping part is provided with a sensing plate, and the support body is provided with at least one sensor corresponding to the sensing plate.

[0017] Furthermore, the pusher clamping assembly is provided with a pusher clamping position for clamping the guide wire, the pusher block is provided with a support block, and the support block is provided with a support position for supporting the guide wire, the support position corresponding to the pusher clamping position.

[0018] Furthermore, the support position is provided with an insertion hole for the external gripper to extend into.

[0019] Furthermore, the support position includes a first support groove and a second support groove, which are located on both sides of the insertion hole, respectively.

[0020] Furthermore, both the first support groove and the second support groove are V-shaped grooves.

[0021] The beneficial effect of this utility model is that, in the guide wire pushing mechanism, the guide wire is clamped by the pusher clamping component, and then the pusher block is driven to move on the support body by the pusher driving component, thereby driving the pusher clamping component that clamps the guide wire to move, so as to automatically push the guide wire; this automatic guide wire pushing method not only improves processing efficiency and reduces labor costs, but also ensures the stability of the yield rate during guide wire processing.

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0033] See Figure 1-2 This embodiment provides a guidewire pushing mechanism, including:

[0034] Support 1;

[0035] Push block 2 is movably mounted on support body 1;

[0036] The pusher drive assembly 3 is used to drive the pusher block 2 to move repeatedly, and the pusher drive assembly 3 is driven to connect with the pusher block 2.

[0037] The pusher clamping assembly 4 is used to clamp the guide wire 7 and is disposed on the pusher block 2.

[0038] When the guide wire 7 pushing mechanism is working, it first clamps the guide wire 7 through the pushing clamping component 4, and then drives the pushing block 2 to move on the support body 1 through the pushing drive component 3, thereby driving the pushing clamping component 4 that clamps the guide wire 7 to move, so as to automatically push the guide wire 7; after completing the processing of one guide wire 7, the pushing drive component 3 can also drive the pushing block 2 to reset on the support body 1, and the pushing clamping component 4 drives the guide wire 7 to reset, so as to assist in completing the unloading of the guide wire 7.

[0039] In this embodiment, the pusher drive assembly 3 includes a pusher drive motor 31 and a pusher screw 32. The pusher drive motor 31 is fixedly mounted on the support body 1. The pusher drive motor 31 is driven to push the pusher block 2 through the pusher screw 32. Specifically, the pusher drive motor 31 drives the pusher screw 32 to rotate, and then drives the pusher block 2 to move on the support body 1 through the transmission between the pusher screw 32 and the pusher block 2 when the pusher screw 32 rotates.

[0040] In this embodiment, the pusher block 2 is movably mounted on the support body 1 via the guide rail 6.

[0041] In this embodiment, the pusher block 2 includes a sliding part 21 and a clamping part 22. The clamping part 22 is fixedly disposed on the left or right side of the sliding part 21. The lower end of the sliding part 21 is movably disposed on the support body 1. The pusher drive assembly 3 is drivenly connected to the sliding part 21.

The gripping part 22 of the pusher block 2 is provided with a support block 5, and the support block 5 is provided with a support position 51 for supporting the guide wire 7. The support position 51 corresponds to the pusher gripping position 42. The provision of the support position 51 can support the guide wire 7, making the position of the guide wire 7 more stable during the pushing process.

[0045] In this embodiment, the support position 51 is provided with an insertion hole 511 for the external gripper to extend into. With the insertion hole 511 provided, when the external gripper is holding the guide wire 7 for feeding, it can directly extend into the insertion hole 511 to place the guide wire 7 on the support position 51 more accurately.

[0046] In this embodiment, the support position 51 includes a first support groove 512 and a second support groove 513, which are located on both sides of the insertion hole 511.
