[0030] Please refer to Figure 1 and Figure 5 , this embodiment provides a medical accessory positioning mechanism 100, which includes a first positioning portion 110 and a second positioning portion 120 that are spaced apart and relatively arranged. The second positioning portion 120 includes a limiting groove 1221 and a carrier 123. The carrier 123 is disposed on a side of the limiting groove 1221 away from the first positioning portion 110; one end of the accessory to be installed 200 is positioned by the first positioning portion 110, and the other end can be clamped in the limiting groove 1221 and extend outward to be supported by the carrier 123.

[0031] Specifically, as Figure 1 shown, the present application provides a medical accessory positioning mechanism 100. The medical accessory positioning mechanism 100 includes a first positioning portion 110 and a second positioning portion 120, and the first positioning portion 110 and the second positioning portion 120 are spaced apart. By setting a preset interval between the first positioning portion 110 and the second positioning portion 120, the two ends of the accessory to be installed 200 can be respectively positioned, and the accurate positioning of the accessory to be installed 200 in the shape of a cable can be ensured by the separate positioning and tensioning of the two ends.

[0032] In an implementable manner of the present application, as Figure 4 shown, the first positioning portion 110 includes a first base 112. At least one positioning member is vertically provided on the first base 112. One end of the fitting 200 to be assembled, which is away from the second positioning portion 120, is sleeved on the positioning member. The first base 112 is used to support the positioning member, and the positioning hole at one end of the fitting 200 to be assembled can achieve the positioning of one end thereof by the positioning member sleeved on the first positioning portion 110.

[0033] It should be noted that the present application does not impose any restrictions on the specific number of the positioning members, as long as it can ensure good positioning accuracy for the end of the fitting 200 to be assembled. Optionally, to further improve the assembly accuracy of the fitting 200 to be assembled, the positioning members include a plurality of them, and the plurality of positioning members are evenly distributed on the edge of the first base 112, so as to facilitate the fitting 200 to be assembled to be sleeved on the outer periphery of the positioning members. Preferably, as Figure 4 shown, four positioning members are vertically provided on the first base 112, and the four positioning members are respectively arranged at the four corners of the first base 112.

[0034] As Figure 5 shown, the second positioning portion 120 includes a limiting groove 1221. One end of the fitting 200 to be assembled is positioned by the first positioning portion 110, and the other end is arranged in the limiting groove 1221 of the second positioning portion 120. The fitting 200 is positioned through the limiting groove 1221; through the settings of the first positioning portion 110 and the second positioning portion 120, the preliminary positioning of the opposite ends of the fitting 200 to be assembled during feeding is realized;

[0035] The fitting 200 arranged in the limiting groove 1221 extends in a direction away from the first positioning portion 110. Since the fitting 200 is in the shape of a cable, in order to avoid the end of the fitting 200 sagging, deviating, falling, or shaking and colliding with the transfer device during the positioning process and subsequent transfer process, as Figure 5 shown, the second positioning portion 120 further includes a carrier 123. The carrier 123 is arranged on the side of the limiting groove 1221 away from the first positioning portion 110. The carrier 123 can support the fitting 200 extending from the limiting groove 1221, and cooperate with the positioning member of the first positioning portion 110 and the limiting groove 1221 of the second positioning portion 120 to jointly realize the support and positioning of the fitting 200 to be assembled.

[0036] The present application provides a medical accessory positioning mechanism 100, comprising a first positioning portion 110 and a second positioning portion 120 which are arranged at intervals and opposite to each other, the second positioning portion 120 comprising a limiting groove 1221 and a bearing member 123, the bearing member 123 being arranged on a side of the limiting groove 1221 away from the first positioning portion 110; one end of the component 200 to be assembled is positioned by the first positioning portion 110, and the other end can be clamped in the limiting groove 1221 and extend outwardly, so as to be supported by the bearing member 123. The above-mentioned medical accessory positioning mechanism 100 can position and support the opposite ends of the component 200 to be assembled through the first positioning portion 110 and the second positioning portion 120, thereby reducing the offset of the component 200 to be assembled during the assembly, loading, picking and moving process, improving the assembly accuracy and assembly efficiency of the component 200 to be assembled, and improving the product yield.

[0037] For example, Figure 4 As shown, the positioning member includes a positioning column 113 and a positioning pin 111 . The positioning column 113 is vertically connected to the first base 112 , and the positioning pin 111 is disposed at one end of the positioning column 113 away from the first base 112 .

[0038] Specifically, Figure 4 As shown, the positioning member is composed of a positioning column 113 and a positioning pin 111. The end of the component 200 to be assembled can be sleeved on the outer periphery of the positioning pin 111 to position one end of the component 200 to be assembled through the positioning pin 111; the setting of the positioning column 113 can ensure that the setting height of the positioning pin 111 is consistent with the bottom height of the limiting groove 1221 of the second positioning portion 120, so that the heights of the two ends of the component 200 to be assembled are consistent.

[0039] In one possible implementation of the present application, Figure 5 As shown, the second positioning portion 120 includes a second base 121, a limiting plate 122 is vertically arranged on the second base 121, and a limiting groove 1221 is arranged on the side of the limiting plate 122 away from the second base 121; the supporting member 123 is connected to the middle part of the limiting groove 1221 and is protruded from the plate surface of the limiting plate 122.

[0040] Specifically, Figure 5 As shown, the second base 121 can provide support force for the limiting plate 122; at least one limiting plate 122 is arranged on the second base 121, and the limiting groove 1221 is arranged on the side of the limiting plate 122 away from the second base 121, so as to clamp one end of the component 200 to be assembled away from the first positioning portion 110; the supporting member 123 is connected to the middle part of the limiting groove 1221, and is protruded from the plate surface of the limiting plate 122, so as to achieve the effect of supporting the component 200 to be assembled.

[0041] It should be noted that the carrier 123 can be a straight plate perpendicular to the plate surface of the limiting plate 122, can also be a rectangular block convexly arranged on the plate surface of the limiting plate 122, or can also be two straight plates arranged perpendicular to each other to form an L-shaped structure. The present application does not impose any restrictions on the specific structure of the carrier 123, as long as it can support the fitting to be installed 200.

[0042] Exemplarily, limiting plates 122 are vertically arranged on opposite sides of the second base 121, and the arrangement directions of the two limiting plates 122 are the same as the arrangement directions of the first positioning portion 110 and the second positioning portion 120; one end of the fitting to be installed 200 away from the first positioning portion 110 can be partially clamped in the limiting groove 1221 of the limiting plate 122.

[0043] Specifically, in order to further improve the assembly accuracy of the fitting to be installed 200, limiting plates 122 are arranged on opposite sides of the second base 121, and the fitting to be installed 200 can be clamped in the limiting grooves 1221 of the two limiting plates 122 for limiting and fixing.

[0044] Optionally, as Figure 5 shown, the carrier 123 includes a first carrier plate 1231 and a second carrier plate 1232. The first carrier plate 1231 is connected to the middle of the limiting groove 1221 and protrudes from the plate surface of the limiting plate 122, and the second carrier plate 1232 is arranged on the side of the first carrier plate 1231 away from the limiting plate 122 to support the first carrier plate 1231.

[0045] Specifically, as Figure 5 shown, the carrier plate includes a first carrier plate 1231. The first carrier plate 1231 is vertically arranged on the plate surface of the limiting plate 122 to support the fitting to be installed 200; in order to improve the stability of the first carrier plate 1231, the carrier plate further includes a second carrier plate 1232, and the second carrier plate 1232 is used to support the first carrier plate 1231. Preferably, the first carrier plate 1231 and the second carrier plate 1232 are vertically arranged so that the carrier plate has an L-shaped structure.

[0046] In order to prevent the fitting to be installed 200 arranged on the first carrier plate 1231 from slipping, a through groove can also be arranged on the first carrier plate 1231 along the extending direction of the fitting to be installed 200, and the fitting to be installed 200 can be clamped in the through groove, so as to prevent the subsequent fitting to be installed 200 from being biased or falling during transportation.

[0047] In an implementable manner of the present application, please refer to Figure 2 and Figure 3, the medical accessory positioning structure further includes a third positioning portion 130, which is movably arranged between the first positioning portion 110 and the second positioning portion 120. The third positioning portion 130 includes a pushing member 131, and the pushing member 131 is used to push the end of the accessory to be installed 200 towards the first positioning portion 110, so that the positioning hole of the accessory to be installed 200 is in close contact with the first positioning portion 110.

[0048] Specifically, as Figure 2 shown, the setting of the third positioning portion 130 can achieve precise positioning of the accessory to be installed 200. Since there is a preset interval between the first positioning portion 110 and the second positioning portion 120, the third positioning portion 130 is movably arranged between the first positioning portion 110 and the second positioning portion 120 to approach or move away from the first positioning portion 110, making the precise positioning adjustment process of the accessory to be installed 200 more efficient.

[0049] As Figure 3 shown, the third positioning portion 130 includes a pushing member 131, and the pushing member 131 can push the end of the accessory to be installed 200 close to the first positioning portion 110 towards the first positioning portion 110, so as to ensure that the positioning pin 111 of the first positioning portion 110 is in close contact with the inner wall of the positioning hole of the accessory to be installed 200, further improving the assembly accuracy of the accessory to be installed 200.

[0050] Exemplarily, as Figure 3 shown, in order to ensure that the pushing member 131 stably clamps the middle of the accessory to be installed 200, the pushing member 131 includes a U-shaped groove 1311 arranged along the connection direction of the first positioning portion 110 and the second positioning portion 120, and one end of the accessory to be installed 200 close to the first positioning portion 110 can be arranged in the U-shaped groove 1311.

[0051] Furthermore, as Figure 3 shown, the third positioning portion 130 includes a cylinder 132, and the cylinder 132 includes a cylinder block and a sliding portion movably arranged in the cylinder block; one end of the sliding portion is fixedly connected to the pushing member 131, and the sliding portion can reciprocate relative to the cylinder 132 to drive the pushing member 131 to approach or move away from the first positioning portion 110.

[0052] Specifically, as Figure 3As shown in the figure, in order to ensure that the pushing member 131 of the third positioning portion 130 moves stably and reliably relative to the first positioning portion 110 and the second positioning portion 120, the third positioning portion 130 further includes a cylinder 132. To facilitate the movement process of the pushing member 131 relative to the first positioning portion 110 and the second positioning portion 120, the cylinder body of the cylinder 132 is disposed on the side of the first positioning portion 110 away from the second positioning portion 120. The sliding portion of the cylinder 132 can drive the pushing member 131 to move along the connection line direction of the first positioning portion 110 and the second positioning portion 120 to approach or move away from the first positioning portion 110, so as to ensure that the positioning pin 111 of the first positioning portion 110 is in close contact with the inner wall of the positioning hole of the to-be-assembled part 200, thereby realizing the precise positioning of the to-be-assembled part 200.

[0053] The above are only optional embodiments of the present invention and are not intended to limit the present invention.
