Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a fatigue detection device for a grid-like sphere. Background Technology

[0002] In medical devices, support nets are often used, which are roughly shaped like a grid ball.

[0003] For example, when it comes to inserting a catheter from inside the thigh to reach the heart for blood clot removal, this procedure is a minimally invasive operation used to diagnose and treat cardiovascular diseases. The catheter is inserted into the heart area by puncturing a superficial blood vessel (usually the femoral artery, located in the groin) for diagnosis or treatment. The medical device used includes a tennis ball, which is elastic and compresses in a small space and automatically relaxes and expands in a larger space until the space can support its expansion to its maximum diameter (returning to its natural state).

[0004] When producing this type of tennis ball, its elasticity needs to be tested, typically through repeated cycles of testing. Currently, this is mainly done manually, which is inefficient and prone to errors, making it difficult to guarantee the actual quality of products that pass the initial testing.

[0005] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0006] In view of this, the present invention addresses the deficiencies of the existing technology, and its main objective is to provide a fatigue testing device for grid spheres. Through the structural design and coordination between the automatic handling device, the testing device, and the automatic transfer device, the automatic handling device and the testing device form an automatic testing system for the workpiece to be tested. Furthermore, through the design of the automatic transfer device, the clamping components are controlled to reciprocate between the automatic handling device and the testing device, thereby achieving cyclic automatic testing of the workpiece without the need for repeated handling by personnel, thus improving the simplicity of the work and the testing efficiency.

[0015] As a preferred embodiment, the automatic transfer device is further provided with a positioning frame, and the second Z-axis moving mechanism is disposed on the positioning frame. The lateral moving mechanism is mounted on the second Z-axis moving mechanism via a movable plate. The clamping assembly is connected to the lateral moving mechanism via an X-axis sliding assembly. The X-axis sliding assembly includes an X-axis guide rail and an X-axis slider disposed on the X-axis moving mechanism. The X-axis slider is slidably connected to the X-axis guide rail. The output end of the lateral moving mechanism is connected to the X-axis slider. The X-axis slider is connected to the clamping assembly, so that the lateral moving mechanism controls the clamping assembly to move back and forth along the extension direction of the X-axis guide rail.

[0016] As a preferred embodiment, the clamping assembly includes at least a clamping head and a clamping drive device, the clamping drive device being connected to the clamping head and controlling the clamping head to clamp or release.

[0058] Preferably, the automatic transfer device 3 is further provided with a positioning frame 34, and the second Z-axis moving mechanism 31 is disposed on the positioning frame 34.

The X-axis sliding assembly includes an X-axis guide rail and an X-axis slider disposed on the X-axis moving mechanism. The X-axis slider is slidably connected to the X-axis guide rail. The output end of the lateral moving mechanism 32 is connected to the X-axis slider. The X-axis slider is connected to the clamping assembly 33, so that the lateral moving mechanism 32 controls the clamping assembly 33 to move back and forth along the extension direction of the X-axis guide rail, thereby realizing the cyclic automatic detection of the test workpiece (each component is cyclically 20 times, allowing the grid sphere 73 to completely relax and expand to its maximum diameter between two cycles).

[0059] Preferably, the clamping assembly 33 includes at least a clamping head 331 and a clamping drive device 332, the clamping drive device 332 being connected to the clamping head 331, and the clamping drive device 332 controlling the clamping head 331 to clamp or release.

[0062] The general working principle of this embodiment is described in detail below:

[0063] The employee manually feeds the mesh ball 73 and fixes it onto the second elastic detection mandrel 72 to obtain the workpiece 7 to be tested. The workpiece 7 is then installed on the product placement position 131 of the product positioning seat 13. The equipment is started by manually pressing the start button 4. The first Y-axis moving mechanism 12 drives the transport base 11 to move along the Y-axis guide rail 16 (reverse along the Y-axis). Then, the first Z-axis moving mechanism 14 controls the product positioning seat 13 to move upward along the Z-axis, so that the product placement position 131 is aligned with the product detection piece 22 along the Z-axis. This allows the product to be tested on the product positioning seat 13 to pass through the test hole 221 of the product detection piece 22 (at least part of it is exposed outside the test hole 221). The second Z-axis moving mechanism 31 drives the lateral moving mechanism 32 to move downward along the Z-axis, causing the clamping assembly 33 to move forward along the X-axis. This controls the clamping assembly 33 to first clamp onto the first elastic detection mandrel 71, and then drive the workpiece to move upward along the Z-axis to release it. After the product inspection piece 22 is removed, the first-stage product is obtained. The second Y-axis moving mechanism 23 controls the Y-axis moving plate 21 to move forward along the Y-axis, so that the product placement position 131 is misaligned with the product inspection piece 22. Then, the second Z-axis moving mechanism 31 drives the transverse moving mechanism 32 to move downward along the Z-axis, so that the clamping assembly 33 moves and positions the first-stage product after one test along the X-axis to the product placement position 131 of the product positioning seat 13. Then, the clamping drive device 332 controls the clamping head 331 to release and move upward. The second Y-axis moving mechanism 23 controls the Y-axis moving plate 21 to move backward along the Y-axis to reset, so that the product inspection piece 22 and the first-stage product are positioned facing each other (the first-stage product is at least partially exposed outside the product inspection piece 22). By controlling the clamping assembly 33 to clamp the first elastic detection spindle 71, the test workpiece is driven to move along the Z-axis, thereby realizing the cyclic automatic detection of the test workpiece.

[0064] The key design feature of this invention lies in the structural design and coordination between the automatic handling device, the detection device, and the automatic transfer device. The automatic handling device and the detection device form an automatic detection system for the workpiece to be tested. Furthermore, through the design of the automatic transfer device, the second Z-axis moving mechanism drives the transverse moving mechanism to move horizontally along the Z-axis, causing the clamping component to move along the X-axis. This controls the clamping component to reciprocate between the automatic handling device and the detection device, thereby achieving cyclic automatic detection of the workpiece without the need for repeated handling by personnel, thus improving the simplicity of the work and the detection efficiency.

[0065] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
