[0031] An embodiment of the present application provides an assembly device, please refer to Figures 1 and 2, the assembly device is used to install the snap ring 30 to the shaft sleeve 40. The assembly device includes a clamping device 10 and a guide fixture 20. The guide fixture 20 is used to be inserted into the shaft sleeve 40 to provide guidance and shaping for the installation of the snap ring 30. The clamping device 10 can pick up and drive the snap ring 30 to move along the guide fixture 20, so that the snap ring 30 is stretched and sleeved on the shaft sleeve 40.

[0032] Referring to FIGS. 3 to 5 b , a clamping device 10 provided in an embodiment of the present application includes a clamping assembly 100, and the clamping assembly 100 includes a picking component 101. The picking component 101 can move between a pressing position and a loading position, and includes a first clamping jaw 110, a second clamping jaw 120, and a connecting frame 130, wherein the first clamping jaw 110 and the second clamping jaw 120 are both arranged on the connecting frame 130. As shown in FIG. 5 a , when the picking component 101 is in the loading position, along the first direction S1, the second clamping jaw 120 is aligned with the sleeve 40, so as to sleeve the retaining ring 30 on the guide fixture 20 inserted in the sleeve 40. As shown in Fig. 5b, when the picking component 101 is in the pressing position, along the first direction S1, the first clamping jaw 110 is aligned with the shaft sleeve 40, and the first clamping jaw 110 can be pressed down along the first direction S1 to be sleeved on the clamping ring 30 of the guide fixture 20, so that the clamping ring 30 is stretched by the guide fixture 20 and sleeved on the shaft sleeve 40. In addition, when the picking component 101 is in the pressing position, along the first direction S1, the second clamping jaw 120 is aligned with the material loading position 201 to pick up the clamping ring 30 at the material loading position 201.

[0033] In the clamping device 10, the first clamping jaw 110 can press the snap ring 30 along the guide fixture 20, so that the snap ring 30 is stretched and pressed onto the sleeve 40, thereby completing the installation of the snap ring 30. In addition, when the first clamping jaw 110 is pressing the snap ring 30, the second clamping jaw 120 is aligned with the loading position 201 and can be used to pick up the snap ring 30 at the same time. Since the first clamping jaw 110 and the second clamping jaw 120 are both arranged on the connecting frame 130, the first clamping jaw 110 and the second clamping jaw 120 can move synchronously between the pressing position and the loading position. That is, in the process of the second clamping jaw 120 picking up the snap ring 30 and moving it to align with the guide fixture 20, the first clamping jaw 110 synchronously moves from the position aligned with the guide fixture 20 to the position staggered with the guide fixture 20, so that the second clamping jaw 120 can easily put the snap ring 30 on the guide fixture 20. This arrangement reduces the waiting time during the process of the pick-up component 101 installing the snap ring 30. By driving the pick-up component 101 to move between the pressing position and the loading position, the snap ring 30 can be efficiently installed on the shaft sleeve 40, thereby improving the installation efficiency of the snap ring 30.

[0034] Please refer to FIG. 6 . In one embodiment, the guide jig 20 extends along the first direction S1. Moreover, in the direction pointing to the sleeve 40 along the first direction S1, the outer diameter of at least a part of the guide jig 20 gradually increases, and the maximum outer diameter of the guide jig 20 is greater than or equal to the outer diameter of the sleeve 40. Thus, when the second clamp 120 drives the retaining ring 30 to be pressed down along the guide jig 20, the guide jig 20 can gradually open the retaining ring 30 so that the retaining ring 30 fits the sleeve 40. It can be understood that the guide jig 20 extending along the first direction S1 means that when the guide jig 20 is inserted into the sleeve 40 or is in the same posture as when it is inserted into the sleeve 40, the guide jig 20 extends along the first direction S1.

[0035] Please refer to FIG. 6 . In one embodiment, the guide fixture 20 includes a positioning section 21, a horn section 22 and a plug-in section 23. The positioning section 21, the horn section 22 and the plug-in section 23 are sequentially connected along the first direction S1. The plug-in section 23 is used to plug with the sleeve 40 so that the guide fixture 20 is inserted into the sleeve 40 as a whole, providing guidance and shaping for the installation of the snap ring 30. When the picking component 101 is in the loading position, the second clamping jaw 120 can cover the snap ring 30 on the positioning section 21. The outer diameter of the positioning section 21 is less than or equal to the inner diameter of the snap ring 30, which is convenient for placing the snap ring 30. The outer diameter of the horn section 22 is larger than the outer diameter of the positioning section 21, so the snap ring 30 can be stretched when it is pressed down from the positioning section 21 to the horn section 22. Moreover, in the direction from the positioning section 21 to the plug-in section 23 along the first direction S1, the outer diameter of the horn section 22 gradually increases, and the maximum outer diameter of the horn section 22 is larger than the outer diameter of the sleeve 40. Thus, the first clamping jaw 110 presses down the snap ring 30 , so that the snap ring 30 can be expanded to a degree substantially the same as the outer diameter of the sleeve 40 , so that the snap ring 30 can be conveniently clamped on the outer periphery of the sleeve 40 .

[0036] It should be noted that the positioning section 21, the horn section 22 and the plug-in section 23 are connected in sequence along the first direction S1, which means that when the guide fixture 20 is inserted into the sleeve 40 or is in the same posture as when it is inserted into the sleeve 40, the positioning section 21, the horn section 22 and the plug-in section 23 are connected in sequence along the first direction S1.

[0037] In one embodiment, the assembly equipment includes a conveying device (not shown in the figure, the same below) and a plurality of carriers (not shown in the figure, the same below), the carrier is used to carry the sleeve 40, and the conveying device is connected to the carrier to switch the carrier located at the clamping device 10. Therefore, when the sleeve 40 and the snap ring 30 carried by a carrier are installed, the conveying device can be used to switch the carrier located at the clamping device 10. The conveying device switches the carrier, and the snap ring 30 can be continuously installed on the sleeve 40 in combination with the reciprocating motion of the picking component.

[0038] Please continue to refer to Figures 4 to 5b. In one embodiment, the first clamp 110 can be opened and clamped. When the picking component 101 is in the pressing position, the first clamp 110 is used to pick up the guide jig 20 to insert the guide jig 20 into the sleeve 40 or pull it out from the sleeve 40. For example, when it is necessary to switch the carrier at the clamping device 10, the guide jig 20 can be pulled out by the first clamp 110, and when another carrier moves to the clamping device 10, the guide jig 20 can be inserted into the sleeve 40 carried by the carrier, so that the guide jig 20 does not move with the carrier. Thus, the guide jig 20 is picked up by the first clamp 110, so that the guide jig 20 can be reused.

[0039] Furthermore, when the first clamping jaw 110 presses down the snap ring 30, the first clamping jaw 110 can also be gradually opened so that the first clamping jaw 110 keeps in contact with the outer surface of the guide fixture 20 to stably press down the snap ring 30. In another embodiment, the first clamping jaw 110 can be configured to have a deformable property so that the first clamping jaw 110 can keep in contact with the outer surface of the guide fixture 20 during the pressing process to stably press down the snap ring 30.

[0040] Please refer to FIG. 4 . In one embodiment, the picking component 101 includes a first clamping unit 140, and the first clamping unit 140 is disposed on the connecting frame 130. The first clamping jaw 110 includes at least two clamping bodies 111, and the first clamping unit 140 is connected to the at least two clamping bodies 111 to drive each clamping body 111 to move away from each other and open. The first clamping unit 140 can also drive each clamping body 111 to move toward each other and clamp to pick up the guide fixture 20. The clamping body 111 is used to push the clamping ring 30 sleeved on the guide fixture 20. When the first clamping jaw 110 is pressed down, the first clamping unit 140 can drive each clamping body 111 to gradually open away from each other, so that the clamping body 111 adapts to the shape of the guide fixture 20 and keeps in contact with the outer surface of the guide fixture 20, so as to push the clamping ring 30 along the outer peripheral surface of the guide fixture 20.

[0041] 4 , in one embodiment, at least one of the clamping bodies 111 is provided with a plurality of push bars 112, which extend along the first direction S1 to push against the clamping ring 30 sleeved on the guide fixture 20. In the circumferential direction around the first direction S1, the plurality of push bars 112 are arranged at intervals.

[0042] Furthermore, the push strip 112 may be configured to have a deformable property so as to adapt to the shape of the guide fixture 20 and stably push against the clamp ring 30 .

[0043] Please refer to FIG. 4 . In one embodiment, the picking component 101 further includes a second clamping unit 150, which is also disposed on the connecting frame 130. The first clamping unit 140 and the second clamping unit 150 can be disposed on opposite sides of the connecting frame 130, respectively, so as to fully utilize the installation space on the connecting frame 130. The second clamping jaw 120 includes at least two clamping bodies 121, and the second clamping unit 150 is connected to the at least two clamping bodies 121 to drive each clamping body 121 to move in a direction of approaching and moving away from each other, so as to clamp and open.

[0044] In one embodiment, the number of the clamping bodies 111 may be two, and the number of the clamping bodies 121 may also be two.

[0045] As shown in FIG. 4 , in one embodiment, the number of the first clamping jaw 110 and the second clamping jaw 120 can be configured to be multiple, so as to synchronously install multiple clamping rings 30 correspondingly on multiple sleeves 40 , thereby improving installation efficiency.

[0046] Please refer to FIG. 3 and FIG. 4. In one embodiment, the clamping device 10 includes a base 300, and the picking component 101 is movably disposed on the base 300. The picking component 101 also includes a first longitudinal movement unit 160 and a second longitudinal movement unit 170. The first longitudinal movement unit 160 is connected to the connecting frame 130 to drive the connecting frame 130 to move along the first direction S1, so that the first clamping jaw 110 and the second clamping jaw 120 move synchronously and rise and fall along the first direction S1. It is easy to understand that when the picking component 101 is in the pressing position, the first clamping jaw 110 moves along the first direction S1 to pick up the guide fixture 20 and pull the guide fixture 20 out of the sleeve 40; the second clamping jaw 120 moves along the first direction S1 to pick up the snap ring 30 located at the upper material position. When the second clamping jaw 120 is in the loading position, the second clamping jaw 120 moves along the first direction S1 to put the snap ring 30 on the guide fixture 20.

[0047] Furthermore, the second longitudinal movement unit 170 is provided on the connecting frame 130, and the second longitudinal movement unit 170 is connected to the first clamping jaw 110 to drive the first clamping jaw 110 to press the clamping ring 30 along the first direction S1. By providing two longitudinal driving units, the first longitudinal movement unit 160 and the second longitudinal movement unit 170, the first clamping jaw 110 can not only move along the first direction S1 with the connecting frame 130 as a whole to a position convenient for interacting with the guide fixture 20, but also the first clamping jaw 110 can further move along the first direction S1 under the drive of the second longitudinal movement unit 170 to push the clamping ring 30 to be stretched along the guide fixture 20 and sleeved on the shaft sleeve 40.

[0048] Please refer to FIG. 3 and FIG. 4. In one embodiment, the clamping assembly 100 further includes a transverse driving unit 102 and a support plate 103. The transverse driving unit 102 is disposed on the base 300, and the support plate 103 is movably disposed on the base 300. The picking component 101 is disposed on the support plate 103, and the transverse driving unit 102 is connected to the support plate 103 to drive the support plate 103 and the picking component 101 to move between the pressing position and the loading position along the second direction S2. The second direction S2 intersects with the first direction S1. Further, the second direction S2 can be arranged perpendicular to the first direction S1.

[0049] Please refer to FIG. 3 and FIG. 7. In one embodiment, the clamping device 10 further includes a conveying assembly 200, and the conveying assembly 200 is used to convey the clamping ring 30 to the clamping assembly 100. The conveying assembly 200 includes a track 210 and a material dividing plate 220, and the track 210 is arranged on the base 300. The track 210 is provided with a material conveying channel (not shown in the figure, the same below), and the conveying channel is used to convey the clamping ring 30. A discharge port (not shown in the figure, the same below) is provided at one end of the material conveying channel, and the material dividing plate 220 is arranged at the end where the discharge port of the track 210 is located. The material dividing plate 220 is provided with a material containing groove 221, and the material dividing plate 220 can move between the material receiving position and the material loading position along the third direction S3. When the material dividing plate 220 is at the material receiving position, along the extension direction of the material conveying channel, the material containing groove 221 is aligned with the discharge port, and the material containing groove 221 is used to receive the clamping ring 30 output from the discharge port. When the material dividing plate 220 is in the loading position, the second clamping jaw 120 can pick up the snap ring 30 in the material storage groove 221, so that the snap ring 30 is transported to the second clamping jaw 120. In addition, when the material dividing plate 220 is in the loading position, the material dividing plate 220 blocks the material outlet. Since the material storage groove 221 is no longer aligned with the material outlet when the material dividing plate 220 is in the loading position, the snap ring 30 can be prevented from falling by blocking the material outlet with the material dividing plate 220.

[0050] The third direction S3 intersects with the first direction S1, and the third direction S3 also intersects with the second direction S2. Further, the third direction S3 may be perpendicular to the first direction S1 and the second direction S2.

[0051] In one embodiment, the conveying assembly 200 further includes a support platform 230 and a material distribution driving unit 240, and the support platform 230 is disposed on the base 300. The material distribution driving unit 240 is disposed on the support platform 230, and the material distribution plate 220 is movably disposed through the support platform 230. The material distribution driving unit 240 is connected to the material distribution plate 220 to drive the material distribution plate 220 to move along the third direction S3 between the material receiving position and the material loading position.

[0052] Please refer to FIG. 8 . In one embodiment, the material storage tank 221 includes a limiting wall 223. The material storage tank 221 is also provided with a first avoidance opening 224, which is located on a side of the material storage tank 221 close to the discharge port, and is used for the clamping ring 30 to enter the material storage tank 221. When the material dividing plate 220 is in the material receiving position, along the extension direction of the material conveying channel (that is, the direction in which the material conveying channel conveys the clamping ring 30), the first avoidance opening 224 is aligned with the discharge port. The limiting wall 223 is located on a side of the material storage tank 221 away from the discharge port, and is used to abut against the clamping ring 30, so that the clamping ring 30 is stably located in the material storage tank 221 and blocks another clamping ring 30 from being output from the discharge port. Further, the shape of the limiting wall 223 can be adapted to the shape of the clamping ring 30 to position the clamping ring 30, so as to facilitate the second clamping jaw 120 to pick up. For example, the limiting wall 223 can be configured as an arc wall.

[0053] Please continue to refer to Figure 8.
