Description

Technical Field

[0001] The invention relates to medical equipment, and in particular to a material transfer device and a medical equipment production line. Background Art

[0002] In the automated production process of medical devices, due to factors such as space and cost, it is often necessary to use multiple circulation lines to transfer materials, and the materials between different circulation lines need to rely on material transfer devices to transfer. The existing material transfer device includes a first clamping component and a second clamping component. When the material is transferred between different circulation lines, it is assumed that the first clamping component clamps the material in the initial state, and the second clamping component does not clamp the material. The first clamping component and the second clamping component first move relative to each other until the first clamping component and the second clamping component clamp the material at the same time, then the first clamping component releases the material, and finally the first clamping component and the second clamping component move relative to each other until the first clamping component and the second clamping component move away from each other. As a result, the material transfer efficiency is slow and needs to be improved. Summary of the invention

[0003] In view of this, it is necessary to provide an improved material transfer device and a medical device production line. The material transfer device can speed up the material transfer efficiency. The medical device production line using the material transfer device has high production efficiency.

[0004] The present invention first provides a material transfer device, including a first clamping assembly and a second clamping assembly, wherein the first clamping assembly and the second clamping assembly are both used to clamp and release materials, the first clamping assembly and the second clamping assembly move relative to each other until the first clamping assembly and the second clamping assembly clamp the material at the same time, and the second clamping assembly elastically clamps the material.

[0005] By adopting the above technical solution, the second clamping component elastically clamps the material. Therefore, no matter whether the material moves from the first clamping component to the second clamping component or from the second clamping component to the first clamping component, the second clamping component can clamp and release the material synchronously with the movement of the material relative to the second clamping component. There is no need to wait for the second clamping component to switch to the released state or the clamped state, thereby speeding up the material transfer efficiency.

[0006] In one embodiment of the present invention, the first clamping assembly moves relative to the second clamping assembly and the first clamping assembly clamps and releases the material in steps.

[0007] In one embodiment of the present invention, the first clamping assembly includes a first clamping arm and a second clamping arm, and the material transfer device also includes a first transfer drive assembly and a second transfer drive assembly, the first transfer drive assembly is used to drive the first clamping arm and the second clamping arm to move relative to each other to clamp and release materials, the second transfer drive assembly drives the first clamping arm and the second clamping arm to move relative to the second clamping assembly, and the first transfer drive assembly and the second transfer drive assembly drive the first clamping arm and the second clamping arm to move in steps.

[0008] In one embodiment of the present invention, the first transfer drive assembly includes a guide block, a first transfer drive member and a first reset member, and the first transfer drive member drives the guide block to move relative to the first clamping assembly. When the guide block moves relative to the first clamping assembly, the distance between the first clamping arm and the second clamping arm decreases to gradually clamp the material or increases to gradually release the material under the guidance of the guide block and the action of the first reset member.

[0009] In one embodiment of the present invention, the guide block is provided with a guide surface, the guide surface abuts against the first clamping arm, and the guide surface guides the first clamping arm to move relative to the second clamping arm.

[0010] In one embodiment of the present invention, the movement of the first clamping assembly relative to the second clamping assembly and the release of the material by the first clamping assembly are performed synchronously.

[0011] By adopting the above technical solution, compared with the movement of the first clamping component relative to the second clamping component and the gradual release of the material distribution by the first clamping component, the movement of the first clamping component relative to the second clamping component and the gradual release of the material by the first clamping component are performed simultaneously, which can further accelerate the material transfer efficiency.

[0012] In one embodiment of the present invention, the second clamping assembly includes a positioning space, and the material enters the positioning space as the first clamping assembly moves relative to the second clamping assembly. The material is clamped by the second clamping assembly when moving in the positioning space, and the first clamping assembly gradually releases the material while the material moves in the positioning space.

[0013] By adopting the above technical solution, the material is clamped by the second clamping assembly when moving in the positioning space. Therefore, even if the first clamping assembly gradually releases the material while the material is moving, the material can be fixed by being clamped by the second clamping assembly.

[0014] In one embodiment of the present invention, the first clamping assembly includes a first clamping arm and a second clamping arm, and the material transfer device also includes a second transfer drive assembly and a guide block. The second transfer drive assembly drives the first clamping arm and the second clamping arm to move relative to the second clamping assembly. When the material enters the positioning space as the first clamping arm and the second clamping arm move, the guide block begins to guide the distance between the first clamping arm and the second clamping arm to gradually increase to loosen the material.

[0015] In one embodiment of the present invention, the guide block is provided with a guide surface, the guide surface abuts against the first clamping arm, and the guide surface guides the first clamping arm to move relative to the second clamping arm.

[0016] By adopting the above technical solution, before the material is transferred to the right place, the first clamping arm and the second clamping arm no longer clamp the material, and the second clamping assembly has already clamped the material. Therefore, the guide block is fixedly arranged on the moving path of the first clamping arm and the second clamping arm, after the second clamping assembly clamps the material and before the material is transferred to the right place, which can also ensure that when the first clamping arm and the second clamping arm no longer clamp the material, the material can be clamped by the second clamping assembly. Therefore, the guide block can be fixedly arranged.

[0017] The present invention further provides a medical device production line, comprising the above-mentioned material transfer device.

[0018] By adopting the above technical solution, the production line of medical equipment using the material transfer device has higher production efficiency.

[0019] In one embodiment of the present invention, the medical device production line includes a first circulation line and a second circulation line, the first circulation line includes a first circulation driving member, a plurality of the first clamping assemblies are provided, and the first circulation driving member drives the plurality of the first clamping assemblies to move in a circulation, and the second circulation line includes a second circulation driving member, a plurality of the second clamping assemblies are provided, and the second circulation driving member drives the plurality of the second clamping assemblies to move in a circulation.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0028] The embodiment of the present invention first provides Figure 1 The material transfer device shown includes a first clamping assembly 100 , a second clamping assembly 200 , a first transfer drive assembly 300 and a second transfer drive assembly 400 .

[0029] Reference Figure 1 and Figure 2 The first clamping assembly 100 includes a mounting member 110, a first clamping arm 120, a second clamping arm 130 and a first reset member. The first clamping arm 120 includes a clamping portion 121 and an adjusting portion 122 connected to each other. The connection between the clamping portion 121 and the adjusting portion 122 is rotatably connected to the mounting member 110, and the clamping portion 121 and the adjusting portion 122 can rotate around the connection between the clamping portion 121 and the adjusting portion 122. The second clamping arm 130 is fixedly connected to the mounting member 110. The clamping portion 121 and the second clamping arm 130 are used to clamp and release the material. The adjusting portion 122 is used to drive the distance between the clamping portion 121 and the second clamping arm 130 to change so as to realize the switching of the state between the clamping portion 121 and the second clamping arm 130 between clamping and releasing the material. When the adjusting portion 122 and the second clamping arm 130 are close to each other, the distance between the clamping portion 121 and the second clamping arm 130 increases to gradually release the material. When the adjusting portion 122 and the second clamping arm 130 move away from each other, the distance between the clamping portion 121 and the second clamping arm 130 decreases to gradually clamp the material. The two ends of the first reset member are respectively connected to the adjusting portion 122 and the second clamping arm 130. When the adjusting portion 122 and the second clamping arm 130 approach each other, they act on the first reset member, so that the elastic deformation degree of the first reset member increases. When the first reset member acts on the adjusting portion 122 to reset the adjusting portion 122, the elastic deformation degree of the first reset member decreases.

[0030] Reference Figure 3 The second clamping assembly 200 includes a first clamping portion 210, a second clamping portion 220, a connecting portion 230, a main body 240 and a limiting portion 250. One end of the first clamping portion 210 and one end of the second clamping portion 220 are respectively connected to the two ends of the connecting portion 230, and the other end of the first clamping portion 210 away from the connecting portion 230 and the other end of the second clamping portion 220 away from the connecting portion 230 are arranged at intervals. The main body 240 surrounds the first clamping portion 210, the connecting portion 230 and the second clamping portion 220. The main body 240 is connected to the first clamping portion 210, the main body 240 and the second clamping portion 220 are arranged at intervals, and the main body 240 and the connecting portion 230 are also arranged at intervals.

[0031] Reference Figure 3 The second clamping portion 220 includes a limiting section 221 and a clamping section 222. The two ends of the clamping section 222 are respectively connected to the connecting portion 230 and the limiting section 221. The minimum distance between the limiting section 221 and the first clamping portion 210 is smaller than the distance between the clamping section 222 and the first clamping portion 210. The end of the limiting section 221 away from the clamping section 222 can guide the material to enter between the clamping section 222 and the first clamping portion 210.

[0032] Reference Figure 3, one end of the limiting portion 250 is connected to the first clamping portion 210, and the other end of the limiting portion 250 is spaced apart from the clamping section 222. A first positioning space 260 and a second positioning space 270 are formed between the clamping section 222 and the first clamping portion 210. The limiting portion 250 is located between the first positioning space 260 and the second positioning space 270. Since the other end of the limiting portion 250 is spaced apart from the clamping section 222, the first positioning space 260 and the second positioning space 270 are in a connected state. After the first positioning space 260 and the second positioning space 270 are connected, a completed positioning space is formed. The limiting portion 250 is smoothly connected to the first clamping portion 210 on one side facing the first positioning space 260, and the limiting portion 250 is smoothly connected to the first clamping portion 210 on one side facing the second positioning space 270.

[0033] Reference Figure 3 , the first clamping part 210 and the second clamping part 220 clamp the material. The first clamping part 210 and the second clamping part 220 can elastically maintain the relative positions of the first clamping part 210 and the second clamping part 220. The second clamping assembly 200 elastically clamps the material, so whether the material moves from the first clamping assembly 100 to the second clamping assembly 200, or the material moves from the second clamping assembly 200 to the first clamping assembly 100, the second clamping assembly 200 clamps and releases the material can be synchronized with the movement of the material relative to the second clamping assembly 200, so there is no need to wait for the second clamping assembly 200 to switch to the release state or the clamping state, so the material transfer efficiency can be accelerated.

[0034] Reference Figure 1 and Figure 4 , the first transfer drive assembly 300 includes a guide block 310 and a first transfer drive member 320. The guide block 310 is provided with a guide groove 311, and the inner wall of the side where the guide groove 311 abuts against the adjustment part 122 is a guide surface 312. The guide surface 312 includes a guide section 312a, a constant section 312b and a recovery section 312c connected in sequence. Among them, the distance between the constant section 312b and the second clamping arm 130 remains unchanged, the distance between the guide section 312a and the second clamping arm 130 gradually decreases from the end away from the constant section 312b to the end close to the constant section 312b, and the distance between the recovery section 312c and the second clamping arm 130 gradually decreases from the end away from the constant section 312b to the end close to the constant section 312b. The first transfer drive member 320 drives the guide block 310 to move relative to the adjustment part 122, so that the adjustment part 122 contacts the guide section 312a and moves along the guide groove 311. Under the guidance of the guide surface 312 and the drive of the first restoring member, the adjusting portion 122 will gradually approach the second clamping arm 130 and gradually move away from the second clamping arm 130 when contacting the guiding section 312a and the restoring section 312c, thereby causing the clamping portion 121 and the second clamping arm 130 to release and clamp the material accordingly.

[0035] Reference Figure 1 The second transfer drive assembly 400 includes a driving wheel 410, a driven wheel 420, a guide rail 430, a guide member 440, a second reset member 450 and a second transfer drive member 460. The second transfer drive member 460 drives the driving wheel 410 to rotate eccentrically, and the driven wheel 420 is located on the rotation path of the driving wheel 410. Therefore, the driving wheel 410 will contact the driven wheel 420 during the eccentric rotation. One end of the guide rail 430 is connected to the axis of the driven wheel 420, and the other end of the guide rail 430 passes through the guide member 440 and is connected to the first clamping assembly 100. Therefore, the guide rail 430 and the guide member 440 are sleeved, so that the guide rail 430 can only move under the guidance of the guide member 440. When the driving wheel 410 contacts the driven wheel 420 during the eccentric rotation, the driven wheel 420 moves under the action of the driving wheel 410 and the guidance of the guide member 440, so that the first clamping assembly 100 and the second clamping assembly 200 move relative to each other. When the action of the driving wheel 410 on the driven wheel 420 can overcome the action of the second reset member 450, the driven wheel 420 will drive the first clamping assembly 100 and the second clamping assembly 200 to move closer to each other, and the elastic deformation degree of the second reset member 450 increases. When the action of the driving wheel 410 on the driven wheel 420 is less than that of the second reset member 450, the driven wheel 420 will drive the first clamping assembly 100 and the second clamping assembly 200 to move away from each other under the action of the second reset member 450, and the elastic deformation degree of the second reset member 450 decreases.

[0036] The first transfer drive assembly 300 drives the first clamping arm 120 and the second clamping arm 130 to move to gradually clamp and release the material, and the second transfer drive assembly 400 drives the first clamping arm 120 and the second clamping arm 130 to approach and move away from the second clamping assembly 200 in steps. More precisely, when the material is transferred from the first clamping assembly 100 to the second clamping assembly 200, the second transfer drive assembly 400 first drives the first clamping arm 120 and the second clamping arm 130 to approach the second clamping assembly 200, so that the second clamping assembly 200 clamps the material. The first transfer drive assembly 300 then drives the first clamping arm 120 and the second clamping arm 130 to move to gradually release the material. When the material is transferred from the second clamping assembly 200 to the first clamping assembly 100, the second transfer drive assembly 400 first drives the first clamping arm 120 and the second clamping arm 130 to approach the second clamping assembly 200, and then the first transfer drive assembly 300 drives the first clamping arm 120 and the second clamping arm 130 to move to the first clamping assembly 100 to clamp the material, and then the second clamping assembly 200 releases the material. Therefore, the first clamping assembly 100 and the second clamping assembly 200 will move relatively to the first clamping assembly 100 and the second clamping assembly 200 to clamp the material at the same time.

[0037] Working process:

[0038] The description is given by assuming that the material is transferred from the first clamping assembly 100 to the second clamping assembly 200 .

[0039] The second transfer drive member 460 drives the driving wheel 410 to rotate eccentrically, so that the driving wheel 410 and the driven wheel 420 contact and drive the driven wheel 420 to move. The driven wheel 420 is acted upon by the driving wheel 410 to overcome the action of the second reset member 450, so that under the guidance of the guide member 440, the driven wheel 420 drives the guide rail 430 and the first clamping assembly 100 to move toward the second clamping assembly 200, and at this time, the elastic deformation degree of the second reset member 450 increases. When the material moves with the first clamping assembly 100 to contact the first clamping part 210 and the second clamping part 220, as the material moves further, the distance between the first clamping part 210 and the second clamping part 220 increases, so that the material can enter the positioning space, and the first clamping part 210 and the second clamping part 220 clamp the material. However, at this time, the first clamping assembly 100 still clamps the material.

[0040] The first transfer drive member 320 drives the guide block 310 to move toward the adjustment portion 122, so that the adjustment portion 122 contacts the guide section 312a and the constant section 312b in sequence. As the adjustment portion 122 moves in the guide groove 311, the adjustment portion 122 gradually approaches the second clamping arm 130, so that the distance between the clamping portion 121 and the second clamping arm 130 increases to gradually release the material. At this time, the first clamping assembly 100 no longer clamps the material.

[0041] The second transfer drive member 460 continues to drive the driving wheel 410 to rotate eccentrically, so that the action of the driving wheel 410 on the driven wheel 420 is less than that of the second reset member 450. At this time, the driven wheel 420 will drive the guide rail 430 and the first clamping assembly 100 to move away from the second clamping assembly 200 under the action of the second reset member 450, and the elastic deformation degree of the second reset member 450 is reduced. In the process of the first clamping assembly 100 moving away from the second clamping assembly 200, the adjustment portion 122 will contact the constant section 312b and the recovery section 312c in turn and finally leave the guide groove 311. In the process of the adjustment portion 122 and the constant section 312b contacting, the relative position of the adjustment portion 122 and the second clamping arm 130 remains unchanged, so that the distance between the clamping portion 121 and the second clamping arm 130 remains unchanged, and the first clamping assembly 100 still no longer clamps the material. During the contact between the adjusting portion 122 and the recovery section 312c, the adjusting portion 122 gradually moves away from the second clamping arm 130, so that the distance between the clamping portion 121 and the second clamping arm 130 decreases. However, at this time, the clamping portion 121 and the second clamping arm 130 cannot clamp the material again. After the adjusting portion 122 leaves the guide groove 311, the relative position of the adjusting portion 122 and the second clamping arm 130 remains unchanged, so that the distance between the clamping portion 121 and the second clamping arm 130 remains unchanged.

[0042] The first moving driving member drives the guide block 310 to reset, completing the transfer of the material from the first clamping assembly 100 to the second clamping assembly 200 .

[0043] The embodiment of the present invention further provides a medical device production line, including a first circulation line, a second circulation line and the above-mentioned material transfer device. The production efficiency of the medical device production line using the material transfer device is high. The first circulation line includes a rotating member and a first circulation drive member. A plurality of guide members 440, a guide rail 430 and a first clamping assembly 100 are provided. The plurality of guide members 440 are fixedly connected to the rotating member, and the plurality of guide members 440, the plurality of guide rails 430 and the plurality of first clamping assemblies 100 correspond one to one. The first circulation drive member drives the rotating member to rotate circumferentially, so that the rotating member drives the plurality of first clamping assemblies 100 to rotate circumferentially, and realizes the cyclic movement of the plurality of first clamping assemblies 100. The second circulation line includes a circulating belt and a second circulation drive member. A plurality of second clamping assemblies 200 are provided, and the plurality of second clamping assemblies 200 are connected to the circulating belt. The second circulation drive member drives the circulating belt to move, so that the circulating belt drives the plurality of second clamping assemblies 200 to move cyclically.

[0044] Example 2

[0045] The difference between Example 2 and Example 1 is that the material is transferred between the first clamping assembly 100 and the second clamping assembly 200 in a different manner.

[0046] In Example 2, the material enters the positioning space as the first clamping arm 120 and the second clamping arm 130 move relative to the second clamping assembly 200, and the material is clamped by the second clamping assembly 200 when moving in the positioning space. When the material moves in the positioning space, the first clamping arm 120 and the second clamping arm 130 move relative to the second clamping assembly 200 and the first clamping assembly 100 gradually releases the material synchronously. The first transfer drive member 320 does not need to be set, and the guide block 310 is in a fixed position. In the process of the first clamping assembly 100 moving toward the second clamping assembly 200, the adjustment portion 122 enters the guide groove 311 and contacts the recovery section 312c and the constant section 312b in sequence. Compared with the movement of the first clamping assembly 100 relative to the second clamping assembly 200 and the gradual release of the material distribution by the first clamping assembly 100, the movement of the first clamping assembly 100 relative to the second clamping assembly 200 and the gradual release of the material by the first clamping assembly 100 are synchronous, which can further speed up the material transfer efficiency. The material is clamped by the second clamping assembly 200 when it moves in the positioning space. Therefore, even if the first clamping assembly 100 gradually releases the material while the material is moving, the material can be fixed by being clamped by the second clamping assembly 200. Before the material is transferred to the position, the first clamping arm 120 and the second clamping arm 130 no longer clamp the material, and the second clamping assembly 200 has already clamped the material. Therefore, the guide block 310 is fixedly set at a position on the moving path of the first clamping arm 120 and the second clamping arm 130 after the second clamping assembly 200 clamps the material and before the material is transferred to the position, which can also ensure that when the first clamping arm 120 and the second clamping arm 130 no longer clamp the material, the material can be clamped by the second clamping assembly 200. Therefore, the guide block 310 can be fixedly set.

[0047] Working process:

[0048] The following description is made using the case where the material is transferred from the first clamping assembly 100 to the second clamping assembly 200 , mainly describing the differences from the working process of Embodiment 1.

[0049] During the movement of the first clamping assembly 100 toward the second clamping assembly 200, as the material moves in the positioning space, the adjusting portion 122 enters the guide groove 311 and contacts the recovery section 312c and the constant section 312b in sequence. During the contact between the adjusting portion 122 and the recovery section 312c, the adjusting portion 122 gradually approaches the second clamping arm 130, so that the distance between the clamping portion 121 and the second clamping arm 130 increases to gradually release the material. At this time, the first clamping assembly 100 no longer clamps the material. During the contact between the adjusting portion 122 and the constant section 312b, the relative position of the adjusting portion 122 and the second clamping arm 130 remains unchanged, so that the distance between the clamping portion 121 and the second clamping arm 130 remains unchanged. Although the first clamping assembly 100 no longer clamps the material at this time, the material is still in contact with the clamping portion 121 and the second clamping arm 130, so that the material can still move in the positioning space under the push of the clamping portion 121 and the second clamping arm 130.

[0050] During the movement of the first clamping assembly 100 away from the second clamping assembly 200, the adjusting portion 122 will contact the constant section 312b and the recovery section 312c in sequence and exit the guide groove 311. During the contact between the adjusting portion 122 and the constant section 312b, the relative position of the adjusting portion 122 and the second clamping arm 130 remains unchanged, so that the distance between the clamping portion 121 and the second clamping arm 130 remains unchanged. During the contact between the adjusting portion 122 and the recovery section 312c, the distance between the adjusting portion 122 and the second clamping arm 130 decreases. However, at this time, the clamping portion 121 and the second clamping arm 130 cannot clamp the material again. After the adjusting portion 122 leaves the guide groove 311, the relative position of the adjusting portion 122 and the second clamping arm 130 remains unchanged, so that the distance between the clamping portion 121 and the second clamping arm 130 remains unchanged.

[0051] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present invention, and are not intended to limit the present invention. As long as they are within the spirit of the present invention, appropriate changes and modifications to the above embodiments are within the scope of protection claimed by the present invention.
