Description

TECHNICAL FIELD

[0001] The present application relates to medical devices, and in particular to a testing device and a medical device production line. BACKGROUND

[0002] Medical devices usually include multiple components. Among these components, some need to be fixed. Therefore, during the automatic production of medical devices, a testing device is used to test whether the fixing between these components is firm. However, some components of medical devices need to be movably coupled, so if the coupling between the components that need to be movably coupled is too firm, it will affect normal use. At present, there is no testing device for the coupling between the components that need to be movably coupled, and it needs to be improved. SUMMARY

[0003] Therefore, it is necessary to provide an improved testing device and a medical device production line. The testing device can test components that need to be movably coupled. The medical devices produced by the medical device production line produced by using the testing device have high reliability.

[0004] The present application first provides a testing device, which includes a testing clamping member and a testing driving member, and a material includes a first component and a second component. The testing clamping member clamps the first component or the second component, and the testing driving member drives the testing clamping member to reciprocate so as to make the first component and the second component reciprocate to separate and assemble.

[0005] By using the above technical solution, the testing driving member drives the testing clamping member to drive the first component and the second component to separate, so as to test whether the coupling between the first component and the second component can meet normal use. After the first component and the second component are separated under the action of the testing driving member, the testing driving member drives the testing clamping member to move reversely, so as to drive the first component and the second component to assemble. Finally, the testing device realizes the testing of the components that need to be movably coupled.

[0006] In an embodiment of the present application, the first component is sleeved in the second component, the first component partially protrudes from the second component, and the testing clamping member clamps the part of the first component that protrudes from the second component.

[0007] In an embodiment of the present application, the testing clamping member drives the part of the first component that protrudes from the second component to move upward relative to the second component so as to separate the first component and the second component.

[0008] By adopting the technical scheme, the first component is separated from the second component by moving upward relative to the second component, which means that the first component is assembled with the second component by moving downward relative to the second component. After the test is completed, the first component still has a tendency to move downward under the action of its own gravity, so that the first component and the second component can remain in the assembled state after the test is completed, thereby avoiding the influence of the test device on the assembly of the first component and the second component after the first component and the second component are separated.

[0009] In an embodiment of the present application, the test device further comprises a clamping driving member, the clamping driving member drives the test clamping member to open and close, and the test driving member is connected with the clamping driving member and drives the clamping driving member to move.

[0010] In an embodiment of the present application, the test device further comprises a movable member, the test driving member comprises a test driving part and an elastic part, the movable member is connected with the test clamping member, one end of the elastic part is connected with the test driving part, and the other end is connected with the movable member, and the test driving part drives the one end of the elastic part to move.

[0011] In an embodiment of the present application, the test device further comprises a position detection member, the position detection member detects the position of the movable member to determine whether the first component and the second component are separated.

[0012] By adopting the technical scheme, when the conveying device conveys the material to the test device, the test driving part drives the positioning part to move downward toward the material, so that the position detection member, the elastic part, the movable member, the clamping driving member and the test clamping member all move toward the material along with the positioning part. When the clamping driving member and the test clamping member move to the set position, the clamping driving member drives the test clamping member to clamp the part of the first component protruding from the second component. Then, the test driving part drives the positioning part to move upward away from the material, so that the position detection member moves upward along with the positioning part. One end of the elastic part moves upward along with the positioning part, and the other end remains linked with the movable member, the clamping driving member and the test clamping member. When the first component and the second component have not been separated, as the positioning part moves upward, the elastic part increases in elastic deformation, and the elastic part increases the force acting on the first component through the movable member, the clamping driving member and the test clamping member.

[0013] When the positioning part moves upward to the set position, if the position detection member moves to the first detection site of the movable member along with the positioning part at this time, it means that the first component and the second component have not been separated within the set movement distance of the positioning part, that is, within the set range of the elastic part, so the material is determined to be unqualified. Subsequently, the clamping driving member drives the test clamping member to release the material, and the position detection member, the elastic part, the movable member, the clamping driving member and the test clamping member all reset along with the positioning part.

[0014] When the positioning part moves up to the set position, if the first part and the second part have been separated at this time, the first part, the test clamping part, the clamping driving part and the movable part will move up under the action of the elastic part, so that the movable part is located at the second detection site of the positioning detection part, and thus the material is determined to be qualified. Subsequently, the test driving part drives the positioning part to move down again, so that the positioning detection part, the elastic part, the movable part, the clamping driving part, the test clamping part and the first part all move with the positioning part towards the second part. When the clamping driving part and the test clamping part move to the set position, the clamping driving part drives the test clamping part to release the first part, and the re-assembly of the first part and the second part is completed. Finally, the test driving part drives the positioning part to move up again, so that the positioning detection part, the elastic part, the movable part, the clamping driving part and the test clamping part all reset with the positioning part. Finally, the reciprocating motion of the separation and assembly of the first part and the second part is completed.

[0015] In an embodiment of the present application, the test device further comprises a movable part and a positioning part, the test driving part comprises a test driving part and an elastic part, the movable part and the test clamping part are connected, the movable part is movable relative to the positioning part, one end of the elastic part is connected with the positioning part, and the other end is connected with the movable part, and the test driving part is connected with the movable part and drives the movable part to move.

[0016] In an embodiment of the present application, the material further comprises a third part, the third part is sleeved on the outside of the second part, and the test device further comprises a third part detection assembly for detecting whether the third part is sleeved on the outside of the second part.

[0017] In an embodiment of the present application, the first part is sleeved in the second part, the first part partially protrudes from the second part, the test clamping part clamps the part of the first part protruding from the second part, and the third part detected by the third part detection assembly and the first part clamped by the test clamping part belong to the same material at the same position.

[0018] By adopting the above technical scheme, when the test driving part drives the first part and the second part to separate and assemble through the test clamping part, the first part moves relative to the second part under the action of the test driving part, so that the second part does not need to move, and naturally the third part does not need to move. Therefore, the third part detection assembly can directly detect whether the third part is sleeved on the outside of the second part.

[0019] The present application further provides a medical instrument production line, which comprises a transfer device and the above test device.

[0020] By adopting the technical scheme, the medical instrument produced by the medical instrument production line adopting the test device has high reliability.

[0021] In an embodiment of the present application, the medical instrument production line further comprises a rejection device, which is used to reject the material that fails the test of the test device from the transfer device.

[0022] In an embodiment of the present application, the material further comprises a third component, and the medical instrument production line further comprises a siliconization device and a sleeving device, the siliconization device is used to siliconize the first component and the second component, and the sleeving device is used to sleeve the third component on the outside of the second component, and the material sequentially passes through the siliconization device, the sleeving device and the test device under the action of the transfer device.

[0030] Embodiments of the present application first provide a testing device as shown in Figure 1 which comprises a force detection assembly 100 and a third component detection assembly 200.

[0031] Referring to Figure 2 , the material 300 comprises a first component 310, a second component 320 and a third component 330. The first component 310 is sleeved inside the second component 320, and the third component 330 is sleeved outside the second component 320. The first component 310 partially protrudes from the second component 320.

[0032] Referring to Figure 1 , the force detection assembly 100 comprises a testing clamp 110, a clamp driving member 120, a movable member 130, a testing driving member 140 and a position detection member 150. The testing driving member 140 comprises a testing driving part 141, a positioning part 142 and an elastic part 143. The clamp driving member 120 is connected with the testing clamp 110 and drives the testing clamp 110 to open and close. The movable member 130 is connected with the clamp driving member 120 so that the movable member 130 and the clamp driving member 120 move synchronously. The positioning part 142 is provided with a slide rail, and the movable member 130 is matched with the slide rail so that the movable member 130 can move relative to the positioning part 142. One end of the elastic part 143 is connected with the movable member 130, and the other end is connected with the positioning part 142. The elastic deformation degree of the elastic part 143 changes with the movement of the movable member 130 relative to the positioning part 142. The testing driving part 141 is connected with the positioning part 142 and drives the positioning part 142 to move. The position detection member 150 is connected on both sides of the positioning part 142, and the position detection member 150 can detect the position of the movable member 130 to determine whether the first component 310 and the second component 320 are separated. In the specific embodiment shown in Figure 1 , the elastic part 143 adopts a spring, and the position detection member 150 adopts a photoelectric sensor. Meanwhile, in the specific embodiment shown inFigure 1 In the specific embodiment shown, the force detection component 100 further includes a limiting member 160, which is connected to the end of the positioning part 142 away from the end connected to the elastic part 143. The test clamping member 110, the clamping drive member 120, and the movable member 130 are connected below the elastic part 143, thereby preventing the movable member 130 from disengaging from the slide rail when the test clamping member 110, the clamping drive member 120, and the movable member 130 move downward under the combined action of the test drive member 140 and their own gravity.

[0033] Reference Figure 1 The third component detection assembly 200 detects whether the third component 330 is sleeved outside the second component 320. The projection of the third component detection assembly 200 on the horizontal plane lies between the projections of the test clamp 110 and the test drive 140 on the horizontal plane. The third component 330 detected by the third component detection assembly 200 and the first component 310 clamped by the test clamp 110 belong to the same material 300 at the same position. The third component detection assembly 200 includes a bracket 210, an adjusting member 220, and a sleeved detection member 230. The adjusting member 220 is sleeved with the bracket 210 and can move along the bracket 210. When the adjusting member 220 moves to a suitable position, the adjusting member can be movably fixed on the bracket 210. The adjusting member 220 is provided with a mounting hole 221, and the sleeved detection member 230 is installed in the mounting hole 221 of the adjusting member 220. When the adjusting member 220 moves relative to the bracket 210, the sleeve detection member 230 moves along with it relative to the bracket 210, thus adapting to different positions of the third component 330. To increase the adaptability of the sleeve detection member 230 to different positions of the third component 330, multiple adjusting members 220 are provided. Multiple adjusting members 220 are sequentially moved and fixed. Figure 1 In the specific embodiment shown, the adjusting member 220 is a clamp, while the sleeve detection member 230 is a fiber optic sensor.

[0034] Work process:

[0035] The stress detection component 100's detection process is as follows:

[0036] When the transferring device 400 transfers the material 300 to the testing device, the testing driving part 141 drives the positioning part 142 to move downward toward the material 300, so that the positioning detection piece 150, the elastic part 143, the movable piece 130, the clamping driving piece 120 and the testing clamping piece 110 all move toward the material 300 with the positioning part 142. When the clamping driving piece 120 and the testing clamping piece 110 move downward to the set position, the clamping driving piece 120 drives the testing clamping piece 110 to clamp the part of the first component 310 protruding from the second component 320. Then, the testing driving part 141 drives the positioning part 142 to move upward away from the material 300, so that the positioning detection piece 150 moves upward with the positioning part 142. One end of the elastic part 143 moves upward with the positioning part 142, and the other end keeps linkage with the movable piece 130, the clamping driving piece 120 and the testing clamping piece 110. When the first component 310 and the second component 320 have not been separated, as the positioning part 142 moves upward, the elastic part 143 increases the degree of elastic deformation, and the elastic part 143 increases the force acting on the first component 310 through the movable piece 130, the clamping driving piece 120 and the testing clamping piece 110.

[0037] When the positioning part 142 moves upward to the set position, if the positioning detection piece 150 moves to the first detection site of the positioning detection piece 150 with the positioning part 142 at this time, it means that the first component 310 and the second component 320 have not been separated within the set moving distance of the positioning part 142, that is, within the set range of the force of the elastic part 143, so the material 300 is determined as unqualified. Then, the clamping driving piece 120 drives the testing clamping piece 110 to release the material 300, and the positioning detection piece 150, the elastic part 143, the movable piece 130, the clamping driving piece 120 and the testing clamping piece 110 all reset with the positioning part 142.

[0038] When the positioning part 142 moves up to the set position, if the first part 310 and the second part 320 have been separated at this time, the first part 310, the test clamp 110, the clamp driving part 120, and the movable part 130 will move up under the action of the elastic part 143, so that the movable part 130 is located at the second detection site of the positioning detection part 150, and thus the material 300 is determined to be qualified. Subsequently, the test driving part 141 drives the positioning part 142 to move down again, so that the positioning detection part 150, the elastic part 143, the movable part 130, the clamp driving part 120, the test clamp 110, and the first part 310 all move with the positioning part 142 towards the second part 320. When the clamp driving part 120 and the test clamp 110 move to the set position, the clamp driving part 120 drives the test clamp 110 to release the first part 310, and the re-assembly of the first part 310 and the second part 320 is completed. Finally, the test driving part 141 drives the positioning part 142 to move up again, so that the positioning detection part 150, the elastic part 143, the movable part 130, the clamp driving part 120, and the test clamp 110 all reset with the positioning part 142. Finally, the reciprocating motion of the separation and assembly of the first part 310 and the second part 320 is completed.

[0039] It should be noted that during the process of the positioning part 142 moving up to the set position, the separation of the first part 310 and the second part 320 can be synchronized with the upward movement of the positioning part 142 to the set position. At this time, the first part 310 will have up-and-down reciprocating motion under the action of the elastic part 143, so that the movable part 130 is not located at the second detection site of the positioning detection part 150. However, at this time, the movable part 130 is also not located at the first detection site of the positioning detection part 150. Therefore, the material 300 is still determined to be qualified.

[0040] The detection process of the third part detection assembly 200 is as follows:

[0041] While the stress detection assembly 100 is detecting a certain material 300, the third part detection assembly 200 detects whether the third part 330 is sleeved outside the second part 320 of the same material 300 at the same position. When the stress detection assembly 100 is detecting, the first part 310 moves relative to the second part 320 under the action of the test driving part 140, so the second part 320 does not need to move, and naturally the third part 330 also does not need to move. Therefore, the third part detection assembly 200 directly detects whether the third part 330 is sleeved outside the second part 320 of the same material 300 at the same position.

[0042] The upward movement of the first component 310 relative to the second component 320 for disassembly means that the first component 310 moves downward relative to the second component 320 for assembly. After the test is completed, the first component 310 still has a tendency to move downward under its own gravity, so that the first component 310 and the second component 320 can remain in the assembled state after the test is completed, thereby avoiding the impact of the test device on the assembly of the first component 310 and the second component 320 after disassembly.

[0043] The test drive 140 drives the test clamp 110 to separate the first component 310 and the second component 320, that is, to test whether the cooperation between the first component 310 and the second component 320 can meet the normal use. After the first component 310 and the second component 320 are separated under the action of the test drive 140, the test drive 140 drives the test clamp 110 to move reversely, thereby driving the first component 310 and the second component 320 to assemble. Finally, the test device realizes the test of the components that need to be cooperated.

[0044] It can be understood that the positioning part 142 no longer moves, and the test drive part 141 can directly drive the movable part 130 to move relative to the positioning part 142 towards the material 300. At this time, the stress detection assembly 100 detects as follows:

[0045] When the conveying device 400 conveys the material 300 to the test position, the test drive part 141 drives the movable part 130 to move downward relative to the material 300, so that the clamping drive 120 and the test clamp 110 move towards the material 300 along with the movable part 130. When the clamping drive 120 and the test clamp 110 move to the set position, the clamping drive 120 drives the test clamp 110 to clamp the part of the first component 310 protruding from the second component 320. During the movement of the movable part 130 towards the material 300, the positioning part 142 does not move. Therefore, the elastic deformation degree of the elastic part 143 increases.

[0046] When the test clamp 110 clamps the first component 310, the test drive part 141 stops acting on the movable part 130. At this time, the elastic part 143 acts on the movable part 130, so that the movable part 130 has a tendency to move upward away from the material 300, so that the clamping drive 120 and the test clamp 110 follow the positioning part 142 to have a tendency to move upward.

[0047] When the test drive unit 141 moves to the set position, if the movable part 130 is located at the first detection point of the positioning detection unit 150, it means that the first component 310 and the second component 320 have not separated, and the material 300 is determined to be unqualified. Subsequently, the clamping drive unit 120 drives the test clamping unit 110 to release the material 300, and the movable part 130 moves upward under the drive of the elastic part 143. The clamping drive unit 120 and the test clamping unit 110 are reset with the movable part 130, and the elastic deformation degree of the elastic part 143 is reduced.

[0048] When the test drive unit 141 moves to the set position, if the first component 310 and the second component 320 separate, the first component 310, the test clamp 110, the clamping drive unit 120, and the movable component 130 will move upward under the action of the elastic part 143, causing the movable component 130 to pass the second detection point of the positioning detection unit 150, thereby determining that the material 300 is qualified. Subsequently, the test drive unit 141 drives the movable component 130 to move downward again, so that the clamping drive unit 120, the test clamp 110, and the first component 310 all move towards the second component 320 along with the movable component 130. When the clamping drive unit 120 and the test clamp 110 move to the set position, the clamping drive unit 120 drives the test clamp 110 to release the first component 310, completing the reassembly of the first component 310 and the second component 320. During the process of the first component 310 moving towards the second component 320 along with the movable component 130, the degree of elastic deformation of the elastic part 143 increases again. Finally, the test drive unit 141 stops acting on the movable part 130 again. At this time, the elastic part 143 acts on the movable part 130, causing the movable part 130 to move upward away from the material 300. As a result, the test clamping part 110 and the clamping drive unit 120 return to their original positions along with the movable part 130, and the elastic deformation of the elastic part 143 decreases. Finally, the reciprocating motion of separating and assembling the first component 310 and the second component 320 is completed.

[0049] It is understandable that the projection of the third component detection assembly 200 on the horizontal plane may not be between the projection of the test clamp 110 on the horizontal plane and the projection of the test drive 140 on the horizontal plane, but may overlap with at least one of the projections of the test clamp 110 on the horizontal plane and the projection of the test drive 140 on the horizontal plane.

The material 300 passes through the siliconizing device 500, the sleeving device 600, the testing device 800, and the rejection device 700 in turn under the action of the transfer device 400. The siliconizing device 500 is used for siliconizing the first component 310 and the second component 320. The sleeving device 600 is used for sleeving the third component 330 on the outside of the second component 320. The rejection device 700 is used for removing the material 300 that fails the test of the testing device 800 from the transfer device 400.
