Description

TECHNICAL FIELD

[0001] The present application relates to the field of medical devices, in particular to an assembling device and a medical device production line. BACKGROUND

[0002] Part of the medical devices need to use O-rings to realize the sealing function. However, in the automatic production process of the medical devices, how to realize the assembling of the O-rings with other components is a problem to be solved. SUMMARY

[0003] Therefore, it is necessary to provide an assembling device and a medical device production line. The assembling device can realize the automatic assembling of the O-rings and the materials. The medical device production line adopting the assembling device has a high degree of automation.

[0004] The present application first provides an assembling device, which comprises a material taking assembly, a first transferring assembly and a second transferring assembly. The material taking assembly is used for clamping O-rings. The first transferring assembly receives the O-rings clamped by the material taking assembly and then transfers the O-rings to the second transferring assembly. The second transferring assembly receives the O-rings from the first transferring assembly and then transfers the O-rings to the materials to realize the assembling of the O-rings and the materials. The material taking assembly clamps part of the O-rings. The first transferring assembly and the second transferring assembly receive the O-rings in a manner of being sleeved in the O-rings.

[0005] By adopting the technical scheme, the material taking assembly clamps the O-shaped ring, and at this time, only part of the O-shaped ring is stressed, so that the circumferential stress of the O-shaped ring is not uniform. Therefore, if the O-shaped ring is in free fall to the material after the material taking assembly releases the O-shaped ring, the O-shaped ring restores the elastic deformation in the free fall process, and the circumferential stress of the O-shaped ring is not uniform when the O-shaped ring is clamped by the material taking assembly, so that the position of the O-shaped ring moves when the elastic deformation is restored and cannot be predicted, so that the O-shaped ring cannot reach the preset position and cannot be assembled with the material. The O-shaped ring is transferred from the material taking assembly to the first transfer assembly, and then transferred from the first transfer assembly to the second transfer assembly. The first transfer assembly and the second transfer assembly are both sleeved in the O-shaped ring, so that the O-shaped ring is in a circumferentially uniform stress state. At this time, the O-shaped ring restores the elastic deformation in the process of transferring to the material, and the center of the position after moving is determined, so that the O-shaped ring can reach the preset position. If only the first transfer assembly is provided, the first transfer assembly needs to move between the material taking assembly and the material, resulting in slow speed. The transfer of the O-shaped ring between the material taking assembly and the material is completed by the first transfer assembly and the second transfer assembly respectively, so that when the next O-shaped ring moves from the material taking assembly to the intermediate position, the previous O-shaped ring can be transferred from the intermediate position to the material, and the first transfer assembly and the second transfer assembly complete the transfer of the O-shaped ring at the intermediate position, thereby speeding up. Finally, the assembly device can realize efficient and automatic assembly of the O-shaped ring and the material.

[0006] In one of the embodiments, the first transfer assembly comprises a first receiving member and a first separating member. The first receiving member is sleeved inside the O-shaped ring to receive the O-shaped ring. The first separating member is sleeved outside the first receiving member. The first separating member moves relative to the first receiving member to drive the O-shaped ring to transfer from the first receiving member to the second transfer assembly.

[0007] By adopting the technical scheme, when the first separating member moves relative to the first receiving member, it will contact the O-shaped ring sleeved outside the first receiving member, thereby driving the O-shaped ring to move away from the first receiving member and transfer to the second transfer assembly.

[0008] In one of the embodiments, the outer diameter of the part where the first receiving member is sleeved with the O-shaped ring remains unchanged along the axial direction.

[0009] In one of the embodiments, the assembly device comprises a first material taking member and a second material taking member. The first material taking member and the second material taking member are inserted into the inside of the O-shaped ring. The first material taking member and the second material taking member move in opposite directions to clamp the O-shaped ring. The O-shaped ring loses the clamping of the first material taking member and the second material taking member when the first material taking member and the second material taking member move towards each other.

[0010] In one of the embodiments, the second transferring assembly comprises a second receiving member and a second separating member, the second separating member is sleeved outside the second receiving member, the second separating member moves relative to the second receiving member to drive the O-ring to transfer from the second receiving member to the material, the outer diameter of the second receiving member is not greater than the outer diameter of the first receiving member, the first receiving member and the second receiving member abut or overlap in the axial direction so that the O-ring is transferred from the first receiving member to be sleeved outside the second receiving member.

[0011] By adopting the above technical scheme, when the first separating member moves relative to the first receiving member, the first separating member drives the O-ring to be separated from the first receiving member. Since the outer diameter of the second receiving member is not greater than the outer diameter of the first receiving member, when the first receiving member and the second receiving member abut or overlap in the axial direction, the O-ring separated from the first receiving member is sleeved outside the second receiving member, thereby realizing the transfer of the O-ring from the first transferring assembly to the second transferring assembly. When the second separating member moves relative to the second receiving member, the second separating member also drives the O-ring to be separated from the second receiving member. Therefore, as long as the material is located below the second receiving member, the O-ring separated from the second receiving member will fall onto the material.

[0012] In one of the embodiments, the part of the first receiving member sleeved with the O-ring comprises a connecting gradual change part and a constant part, the outer diameter of the gradual change part gradually increases and then remains unchanged along the axial direction, the outer diameter of the constant part remains unchanged along the axial direction, the gradual change part and the constant part are coaxial and the end of the gradual change part with the maximum outer diameter is connected with the constant part, and the first separating member is sleeved outside the constant part.

[0013] By adopting the above technical scheme, when the O-ring is sleeved on the gradual change part, the O-ring can move along the gradual change part under the action of an external force, and the inner diameter of the O-ring also increases with the increase of the outer diameter of the gradual change part. When the O-ring moves to be sleeved on the constant part, the inner diameter of the O-ring does not need to continue to increase. When the first separating member moves relative to the constant part, the first separating member will contact the O-ring sleeved on the constant part, thereby driving the O-ring to leave the constant part.

[0014] In one of the embodiments, the assembling device comprises a first material taking member and a second material taking member, one of the first material taking member and the second material taking member is inserted into the inside of the O-ring, the other of the first material taking member and the second material taking member is located outside the O-ring, and the first material taking member and the second material taking member move towards each other to clamp the O-ring.

[0015] By adopting the technical scheme, when the first material taking member and the second material taking member clamp the O-shaped ring, only part of the O-shaped ring is stressed. Meanwhile, the unstressed part of the O-shaped ring is far away from the stressed part of the O-shaped ring, so when the O-shaped ring is large in size and soft in material, the unstressed part of the O-shaped ring is prone to sagging relative to the stressed part of the O-shaped ring under the action of gravity. Therefore, if the outer diameter of the part of the first receiving member sleeved with the O-shaped ring remains unchanged along the axial direction, when the first material taking member and the second material taking member no longer clamp the O-shaped ring, the O-shaped ring cannot be sleeved on the outside of the first receiving member in the process of free fall, and naturally cannot finally complete the assembly of the O-shaped ring and the material. The setting of the gradual change part enables the O-shaped ring to be sleeved on the outside of the first receiving member in the process of free fall, so that the assembly of the O-shaped ring and the material can be finally completed.

[0016] In one of the embodiments, the assembly device further comprises an adjusting member and an adjusting driving member, the adjusting driving member drives the adjusting member to act on the O-shaped ring so that the O-shaped ring moves from being sleeved on the gradual change part to being sleeved on the constant part.

[0017] In one of the embodiments, the second transfer assembly comprises a second receiving member and a second separating member, the second separating member is sleeved on the outside of the second receiving member, the second separating member moves relative to the second receiving member to drive the O-shaped ring to transfer from the second receiving member to the material, the second receiving member is provided with an accommodating groove accommodating the gradual change part, when the O-shaped ring moves to abut against the second receiving member under the driving of the first separating member, the outer diameter of the O-shaped ring is greater than the outer diameter of the second receiving member.

[0018] By adopting the technical scheme, when the second separating member moves relative to the constant part, the second separating member drives the O-shaped ring to separate from the constant part. When the O-shaped ring moves to abut against the second receiving member, the outer diameter of the O-shaped ring is greater than the outer diameter of the second receiving member, so that the O-shaped ring can be sleeved on the outside of the second receiving member. If the O-shaped ring is located in the gradual change part at this time, the O-shaped ring has a tendency to spontaneously restore the elastic deformation when moving in the gradual change part, so that the O-shaped ring separated from the constant part can be spontaneously sleeved on the outside of the second receiving member.

[0019] The application further provides a medical instrument production line comprising the assembly device.

[0020] By adopting the technical scheme, the medical instrument production line adopting the assembly device has a high degree of automation. BRIEF DESCRIPTION OF DRAWINGS

The term "and / or" used in the specification of the present application includes any and all combinations of one or more of the related listed items.

[0031] Referring to Figure 1 , the present application first provides an assembling device, comprising a taking component 100, a first transferring component 200 and a second transferring component 300.

[0032] Referring to Figure 2The first and second material taking members 110 and 120 are inserted into the inside of the O-ring 500. After the first and second material taking members 110 and 120 move in opposite directions inside the O-ring 500, the first and second material taking members 110 and 120 clamp the O-ring 500. After the first and second material taking members 110 and 120 clamp the O-ring 500, when the first and second material taking members 110 and 120 move the O-ring 500, the O-ring 500 is partially in contact with the auxiliary material taking member 130, so that the portion of the O-ring 500 in contact with the auxiliary material taking member 130 is limited from further movement by the auxiliary material taking member 130, so that the O-ring 500 rotates at the portion of the O-ring 500 in contact with the first and second material taking members 110 and 120. After the first and second material taking members 110 and 120 move in opposite directions inside the O-ring 500, the first and second material taking members 110 and 120 no longer clamp the O-ring 500.

[0033] Referring to Figure 2The first transferring assembly 200 includes a first receiving member 210, a first separating member 220, a first driving member 230 and a horizontal driving member 240. The outer diameter of the portion of the first receiving member 210 sleeved with the O-ring 500 remains unchanged along the axial direction. The first receiving member 210 is sleeved inside the O-ring 500 to receive the O-ring 500. The first separating member 220 is sleeved outside the first receiving member 210. The first driving member 230 drives the first separating member 220 to move relative to the first receiving member 210, so that the first separating member 220 drives the O-ring 500 to move relative to the first receiving member 210, so that the O-ring 500 is transferred to the second transferring assembly 300 from the first receiving member 210. The first receiving member 210 and the first driving member 230 are connected with the horizontal driving member 240, so that the horizontal driving member 240 can simultaneously drive the first receiving member 210, the first separating member 220 and the first driving member 230 to move, so that the first receiving member 210 moves close to the material taking assembly 100 and away from the material taking assembly 100. When the first material taking member 110 and the second material taking member 120 still clamp the O-ring 500, the horizontal driving member 240 drives the first receiving member 210 to move close to the material taking assembly 100, and the portion of the O-ring 500 abutting against the auxiliary material taking member 130 will first contact the first receiving member 210, so that the O-ring 500 is sleeved outside the first receiving member 210. With the further movement of the first receiving member 210 driven by the horizontal driving member 240, most of the O-ring 500 is sleeved outside the first receiving member 210. At this time, the first material taking member 110 and the second material taking member 120 move towards each other inside the O-ring 500 to the O-ring 500 no longer being clamped by the first material taking member 110 and the second material taking member 120. At the same time, the first material taking member 110 and the second material taking member 120 move away from the first receiving member 210, so that most of the O-ring 500 is limited by the auxiliary material taking member 130 and does not move with the first material taking member 110 and the second material taking member 120, so that when the first material taking member 110 and the second material taking member 120 completely exit the inside of the O-ring 500, the O-ring 500 is completely sleeved outside the first receiving member 210.

[0034] Referring to Figure 3 The second transferring assembly 300 includes a second receiving member 310, a second separating member 320, a second driving member 330, a vertical driving member 340 and an assembling driving member 350. The outer diameter of the second receiving member 310 is not greater than the outer diameter of the first receiving member 210. In Figure 1The first receiving member 210 is provided with a groove 211 at one end close to the second receiving member 310, and the second receiving member 310 is capable of being clamped into the groove 211 at one end close to the first receiving member 210, so that the outer diameter of the second receiving member 310 is smaller than that of the first receiving member 210. The axial end surface of the second receiving member 310 is capable of being moved to abut against the axial end surface of the first receiving member 210 or the second receiving member 310 and the first receiving member 210 are overlapped in the axial direction, so that the O-ring 500 is capable of being transferred from being sleeved outside the first receiving member 210 to being sleeved outside the second receiving member 310. The second separating member 320 is sleeved outside the second receiving member 310. The second driving member 330 drives the second separating member 320 to move relative to the second receiving member 310, so that the second separating member 320 drives the O-ring 500 to move relative to the second receiving member 310, so that the O-ring 500 is separated from the second receiving member 310 and is transferred to the material 600. The second receiving member 310 and the second driving member 330 are connected with the vertical driving member 340, so that the vertical driving member 340 is capable of simultaneously driving the second receiving member 310, the second separating member 320 and the second driving member 330 to move, so that the second receiving member 310 is close to and away from the first receiving member 210. The assembly driving member 350 is connected with and drives the vertical driving member 340 to move, so as to simultaneously drive the second receiving member 310, the second separating member 320 and the second driving member 330 to move. Under the joint action of the vertical driving member 340 and the assembly driving member 350, the second receiving member 310 is capable of being moved above the material 600.

[0035] Working process:

[0036] The horizontal driving member 240 drives the first receiving member 210, the first separating member 220 and the first driving member 230 to be close to the material taking assembly 100. During the movement of the first receiving member 210, the part of the O-ring 500 abutting against the auxiliary material taking member 130 is first contacted with the first receiving member 210, so that the part of the O-ring 500 is sleeved outside the first receiving member 210, and then most of the O-ring 500 is sleeved outside the first receiving member 210. At this time, the first material taking member 110 and the second material taking member 120 move towards each other inside the O-ring 500 to the O-ring 500 no longer being clamped by the first material taking member 110 and the second material taking member 120, and the first material taking member 110 and the second material taking member 120 move away from the first receiving member 210, the first material taking member 110 and the second material taking member 120 completely exit the inside of the O-ring 500, and the O-ring 500 is completely sleeved outside the first receiving member 210.

[0037] The horizontal drive member 240 drives the first receiving member 210, the first separating member 220 and the first drive member 230 away from the material taking assembly 100 and moves to below the second transferring assembly 300. The vertical drive member 340 drives the second receiving member 310, the second separating member 320 and the second drive member 330 to approach the first receiving member 210, so that the end of the second receiving member 310 close to the first receiving member 210 is clamped into the groove 211. The first drive member 230 drives the first separating member 220 to move relative to the first receiving member 210, thereby driving the O-ring 500 to be separated from the first receiving member 210 and to be sleeved outside the second receiving member 310. The vertical drive member 340 drives the second receiving member 310, the second separating member 320 and the second drive member 330 away from the first receiving member 210, so that the end of the second receiving member 310 close to the first receiving member 210 is away from the groove 211.

[0038] The assembly drive member 350 drives the vertical drive member 340, the second receiving member 310, the second separating member 320 and the second drive member 330 to move close to the material 600, so that the second receiving member 310 moves to above the material 600. The second drive member 330 drives the second separating member 320 to move relative to the second receiving member 310, thereby driving the O-ring 500 to be separated from the second receiving member 310. The O-ring 500 freely falls to the preset position of the material 600 under the action of its own gravity, and the assembly is completed.

[0039] The taking component 100 clamps the O-ring 500, and at this time, the O-ring 500 is only partially stressed, resulting in uneven circumferential stress of the O-ring 500. Therefore, if the O-ring 500 is adopted in the manner of free falling to the material 600 after the taking component 100 releases the O-ring 500, the O-ring 500 restores the elastic deformation in the process of free falling, and the O-ring 500 is unevenly stressed in the circumferential direction when clamped by the taking component 100, so that the position of the O-ring 500 moves when restoring the elastic deformation and cannot be predicted, so that the O-ring 500 cannot reach the preset position and cannot be assembled with the material 600. The O-ring 500 is transferred from the taking component 100 to the first transfer component 200 and then from the first transfer component 200 to the second transfer component 300, and the first transfer component 200 and the second transfer component 300 are both sleeved inside the O-ring 500, so that the O-ring 500 is in a circumferentially uniform stress state. At this time, the O-ring 500 restores the elastic deformation in the process of transferring to the material 600, and the center of the position after the movement is determined, so that the O-ring 500 can reach the preset position. If only the first transfer component 200 is provided, the first transfer component 200 needs to move between the taking component 100 and the material 600, resulting in a slow speed. The transfer of the O-ring 500 between the taking component 100 and the material 600 is completed by the first transfer component 200 and the second transfer component 300 respectively, so that when the next O-ring 500 moves from the taking component 100 to the intermediate position, the previous O-ring 500 can be transferred from the intermediate position to the material 600, and the first transfer component 200 and the second transfer component 300 complete the transfer of the O-ring 500 at the intermediate position, thereby speeding up. Finally, the assembly device can realize efficient and automatic assembly of the O-ring 500 and the material 600.

[0040] The application further provides a medical instrument production line comprising the above-mentioned assembly device. The medical instrument production line adopting the assembly device has a high degree of automation.

[0041] It can be understood that the part of the first receiving member 210 sleeved with the O-ring 500 can include a connected gradual change part and a constant part. The outer diameter of the gradual change part gradually increases and then remains unchanged along the axial direction. The outer diameter of the constant part remains unchanged along the axial direction. The gradual change part and the constant part are coaxial, and the end of the gradual change part with the largest outer diameter is connected with the constant part. The first separating member 220 is sleeved outside the constant part. At this time, the auxiliary material taking member 130 is not required to be arranged, and one of the first material taking member 110 and the second material taking member 120 is inserted into the inside of the O-ring 500, and the other of the first material taking member 110 and the second material taking member 120 is located outside the O-ring 500. The first material taking member 110 and the second material taking member 120 move towards each other to clamp the O-ring 500. At the same time, the assembly device further includes an adjusting assembly 400. The adjusting assembly 400 includes an adjusting member 410 and an adjusting driving member 420. The adjusting driving member 420 drives the adjusting member 410 to act on the O-ring 500, so that the O-ring 500 moves from being sleeved on the gradual change part to being sleeved on the constant part. Correspondingly, compared with the constant part, the gradual change part is closer to the second receiving member 310, and therefore the second receiving member 310 is provided with an accommodation groove which accommodates the gradual change part at the end close to the gradual change part. When the O-ring 500 moves to abut against the second receiving member 310 under the driving of the first separating member 220, the outer diameter of the O-ring 500 is greater than the outer diameter of the second receiving member 310, so that the O-ring 500 can be transferred from the constant part to be sleeved outside the second receiving member 310. When the first material taking member 110 and the second material taking member 120 clamp the O-ring 500, only part of the O-ring 500 is stressed. At the same time, the part of the O-ring 500 which is not stressed is far away from the part of the O-ring 500 which is stressed, so when the size of the O-ring 500 is large and the material quality of the O-ring 500 is soft, the part of the O-ring 500 which is not stressed is prone to sagging relative to the part of the O-ring 500 which is stressed under the action of its own gravity. Therefore, if the outer diameter of the part of the first receiving member 210 sleeved with the O-ring 500 remains unchanged along the axial direction, when the first material taking member 110 and the second material taking member 120 no longer clamp the O-ring 500, the O-ring 500 will not be able to be sleeved outside the first receiving member 210 in the process of free falling, and naturally the assembly of the O-ring 500 and the material 600 cannot be finally completed. The arrangement of the gradual change part makes the O-ring 500 be able to be sleeved outside the first receiving member 210 in the process of free falling, so that the assembly of the O-ring 500 and the material 600 can be finally completed. When the O-ring 500 is sleeved on the gradual change part, the adjusting driving member 420 drives the adjusting member 410 to act on the O-ring 500, so that the O-ring 500 moves along the gradual change part, and at the same time the inner diameter of the O-ring 500 also increases with the increase of the outer diameter of the gradual change part. When the O-ring 500 moves to be sleeved on the constant part, the inner diameter of the O-ring 500 no longer needs to continue to increase, at this time, the adjusting driving member 420 no longer drives the adjusting member 410 to act on the O-ring 500.When the first separating piece 220 moves relative to the constant part, it will contact the O-ring 500 sleeved on the constant part, thereby driving the O-ring 500 to move away from the constant part. When the O-ring 500 moves from the constant part to the gradual change part, the O-ring 500 has a tendency to spontaneously restore the elastic deformation when moving in the gradual change part. Therefore, the O-ring 500 separated from the constant part can spontaneously be sleeved on the outside of the second receiving piece 310 when moving in the gradual change part to abut against the second receiving piece 310.

[0042] The technical features of the above-described embodiments can be combined in any manner.
