Description

Technical Field

[0001] This application relates to the field of bearing assembly technology, specifically to a pick-and-place device that can easily distinguish different bearing specifications. Background Technology

[0002] Currently, eight-speed automatic transmissions are widely used in the automotive industry, and these transmissions are typically equipped with multiple axial thrust bearings of different specifications. Because these thrust bearings are all similar annular plates, and only differ slightly in outer diameter and inner ring size, it is almost impossible for the human eye to directly distinguish the appropriate thrust bearing for assembly when these similar-sized thrust bearings are mixed together.

[0003] Therefore, if operators do not carefully distinguish the specifications of each planar bearing, they will often send the wrong planar bearing to the wrong workstation for assembly, which will lead to serious quality accidents. Utility Model Content

[0004] To address the aforementioned technical problems and achieve at least one advantage of this application, this application provides a pick-and-place device capable of easily distinguishing different bearing specifications, for positioning at a predetermined height on a workstation support, wherein the pick-and-place device capable of easily distinguishing different bearing specifications includes:

[0005] A limiting cylinder is fixedly connected to the workstation bracket, and the limiting cylinder is provided with a limiting channel of a predetermined inner diameter along the direction from top to bottom, and the limiting channel is provided to pass through both ends of the limiting cylinder.

[0006] A loading component includes a loading rod and a fixing member, wherein the loading rod is detachably connected to the limiting cylinder and extends toward the limiting cylinder to form a loading portion of a predetermined size for at least one planar bearing to be sleeved and assembled, the fixing member is provided with a predetermined axial length and is detachably connected to a predetermined position on the extended end of the loading portion in a through manner, and the projection of the fixing member on the loading portion on the same horizontal plane only partially overlaps with that of the loading portion, thereby, when the loading rod is connected to the limiting cylinder, the loading portion is provided to be at least partially accommodated in the limiting channel;

[0007] The material handling platform is located below the limiting cylinder and maintains a predetermined distance from the lower port of the limiting channel and the extension end of the loading part.

[0008] According to one embodiment of this application, the loading rod is further provided with a hole of a predetermined size, the hole being disposed through the middle of the loading part in a direction parallel to the forming direction of the loading part.

[0009] According to one embodiment of this application, the feeding rod extends radially outward from the end connected to the limiting cylinder to form a step, the step is disposed around the circumferential position of the feeding part, and the cross-sectional diameter of the step is disposed larger than the cross-sectional diameter of the limiting cylinder.

[0010] According to one embodiment of this application, the feeding rod extends on the side away from the feeding portion to form a gripping portion, and the extending direction of the gripping portion forms a predetermined angle with the plane where the step is located.

[0011] According to one embodiment of this application, the extension length of the loading part is set to be greater than the axial length of the limiting channel, and the axial length of the fixing member is less than the inner diameter of the limiting channel, so that when the loading rod is connected to the limiting cylinder, the fixing member is positioned outside the limiting channel.

[0012] According to one embodiment of this application, the extension length of the loading part is set to be less than the axial length of the limiting channel, and the limiting cylinder forms a side opening communicating with the limiting channel. The side opening is formed by extending from one end of the limiting cylinder in a downward direction to the other end, and the axial length of the fixing member is set to be greater than the inner diameter of the limiting channel. Thus, when the loading rod is connected to the limiting cylinder, the fixing member is set to be located at least partly inside the limiting cylinder and at least partly outside the limiting cylinder.

[0013] According to one embodiment of this application, the loading rod is further provided with a positioning part adjacent to the loading part. The positioning part surrounds the outer periphery of the loading part, and the cross-sectional diameter of the positioning part is set to be smaller than the cross-sectional diameter of the step. The size of the positioning part is adapted to the inner diameter of the limiting channel, and the loading part is also provided in the middle of the positioning part.

[0014] According to one embodiment of this application, the material handling platform has a front side located below the limiting cylinder and a rear side opposite to the front side, and the material handling platform is provided to form a recess that penetrates the front side and the rear side by a predetermined length from the outer periphery to the center, the recess being located at the axial position of the loading part.

[0022] The following description is intended to disclose this application and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of this application defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of this application.

[0023] Those skilled in the art should understand that, in the disclosure of this application, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.

[0024] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0025] refer to Figures 1 to 3A preferred embodiment of the present application of a pick-and-place device that can easily distinguish different bearing specifications will be described in detail below. The pick-and-place device that can easily distinguish different bearing specifications is used to be positioned at a predetermined height on a workstation bracket 91. The pick-and-place device that can easily distinguish different bearing specifications includes a limiting cylinder 10, a loading member 20 and a picking platform 30.

[0026] Specifically, the limiting cylinder 10 is fixedly connected to the workstation bracket 91, and the limiting cylinder 10 is provided with a limiting channel 101 of a predetermined inner diameter along the direction from top to bottom, wherein the limiting channel 101 is provided to pass through both ends of the limiting cylinder 10.

[0027] The loading component 20 includes a loading rod 21 and a fixed material component 22. The loading rod 21 is detachably connected to the limiting cylinder 10, and the loading rod 21 extends toward the limiting cylinder 10 to form a loading portion 211 of a predetermined size for at least one planar bearing 92 to be fitted and assembled. The fixed material component 22 is provided with a predetermined axial length, and the fixed material component 22 is detachably connected to a predetermined position on the extended end of the loading portion 211 in a through manner, and its projection on the same horizontal plane only partially overlaps with that of the loading portion 211, so as to restrict the axial movement of the planar bearing 92 along the loading portion 211. Thus, when the loading rod 21 is connected to the limiting cylinder 10, the loading portion 211 is configured to be at least partially accommodated in the limiting channel 101.

[0028] It should be noted that if a certain planar bearing 92 cannot be directly fitted into the loading part 211, it indicates that the inner ring size of the planar bearing 92 does not meet the assembly requirements. When a predetermined number of planar bearings 92 have been fitted into the loading part 211, the fixing part 22 can be made to pass through the loading part 211 so that the planar bearings 92 fitted into the loading part 211 are limited and cannot detach from the loading part 211 along the axial direction of the loading part 211 under the action of gravity. At this time, the loading rod 21 can be connected to the limiting cylinder 10. If the loading rod 21 cannot make the loading part 211 be received in the limiting channel 101, it indicates that the loading part 211 is fitted with a planar bearing 92 whose outer diameter does not meet the assembly requirements.

[0029] The material handling platform 30 is disposed below the limiting cylinder 10, and maintains a predetermined distance from the lower port of the limiting channel 101 and the extension end of the loading part 211.

[0030] Those skilled in the art will understand that when the loading part 211, which is equipped with the planar bearing 92, is housed in the limiting channel 101, the fixing member 22 can be removed from the loading part 211 so that the fixing member 22 no longer restricts the planar bearing 92 assembled on the loading part 211. At this time, the planar bearing 92 can gradually detach from the loading part 211 along the axial direction under the action of gravity, and the planar bearing 92 detached from the loading part 211 can be directly carried by the picking platform 30. At this time, the operator can remove the planar bearing 92 carried by the picking platform 30 from the gap between the picking platform 30 and the lower end of the limiting channel 101.

[0031] It should be further explained that the predetermined distance between the material handling platform 30 and the lower port of the limiting channel 101 and the extension end of the loading part 211 is set to be greater than the thickness of one of the planar bearings 92 and less than the sum of the thicknesses of two planar bearings 92. That is, the operator can only take out one planar bearing 92 from the gap at a time to prevent the excess planar bearings 92 from falling off prematurely.

[0032] Preferably, the loading rod 21 is further provided with a hole 2101 of a predetermined size. The hole 2101 is provided to penetrate the middle of the loading part 211 in a direction parallel to the forming direction of the loading part 211. In this way, the overall weight of the loading rod 21 after assembling the plane bearing 92 is reduced, thereby making it easier for the operator to manually connect the loading rod 21 to the limiting cylinder 10.

[0033] Preferably, the loading rod 21 extends radially outward from the end connected to the limiting cylinder 10 to form a step 212. The step 212 is arranged around the circumference of the loading part 211, and the cross-sectional diameter of the step 212 is set to be larger than the cross-sectional diameter of the limiting cylinder 10. Thus, when the loading rod 21 is connected to the limiting cylinder 10, due to the arrangement of the step 212, the loading rod 21 is at least partially located outside the limiting channel 101. Therefore, the operator can apply force to the step 212 when the plane bearing 92 on the loading part 211 is completely removed, so as to separate the loading rod 21 from the limiting cylinder 10.

[0034] More preferably, the loading rod 21 extends to form a gripping part 213 on the side away from the loading part 211. More preferably, the extending direction of the gripping part 213 forms a predetermined angle with the plane where the step 212 is located. In this way, the operator can apply force to the gripping part 213 with his / her hand to facilitate connecting the loading rod 21 to the limiting cylinder 10 or separating the loading rod 21 from the limiting cylinder 10.

[0035] In one embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the extension length of the loading part 211 is set to be greater than the axial length of the limiting channel 101, and the axial length of the fixing part 22 is less than the inner diameter of the limiting channel 101. Therefore, when the loading rod 21 is connected to the limiting cylinder 10, the fixing part 22 is located outside the limiting channel 101. That is, the fixing part 22 can be directly exposed in the gap between the picking platform 30 and the limiting cylinder 10, so that the operator can directly separate the fixing part 22 from the loading part 211, thus facilitating the separation operation.

[0036] In another embodiment, such as Figure 4 As shown, the extension length of the loading part 211 is set to be less than the axial length of the limiting channel 101, and the limiting cylinder 10 forms a side opening 102 communicating with the limiting channel 101. The side opening 102 is set to extend from one end of the limiting cylinder 10 to the other end in a downward direction. The axial length of the fixing member 22 is set to be greater than the inner diameter of the limiting channel 101. Therefore, when the loading rod 21 is connected to the limiting cylinder 10, the fixing member 22 is set to be located at least partly inside the limiting cylinder 10 and at least partly outside the limiting cylinder 10.

[0037] Understandably, the operator can directly apply force with their hand to the part of the fixed part 22 located outside the limiting cylinder 10, so that the fixed part 22 can be separated from the limiting cylinder 10 from the limiting channel 101 to the side opening 102, so as to separate from the loading part 211, thereby so that the plane bearing 92 assembled on the loading part 211 is no longer restricted and can be separated from the loading part 211 by gravity.

[0038] Preferably, the loading rod 21 is further provided with a positioning part 214 adjacent to the loading part 211. The positioning part 214 surrounds the outer periphery of the loading part 211, and the cross-sectional diameter of the positioning part 214 is set to be smaller than the cross-sectional diameter of the step 212. Furthermore, the size of the positioning part 214 is adapted to the inner diameter of the limiting channel 101. In addition, the loading part 211 is also provided in the middle of the positioning part 214.

[0039] It is understood that when the loading rod 21 is connected to the limiting cylinder 10, the positioning part 214 is located in the limiting channel 101 along with the loading part 211. Since the positioning part 214 is adapted to the limiting channel 101, and the loading part 211 is located in the middle of the positioning part 214, the loading part 211 can be coaxial with the limiting channel 101. In other words, when the planar bearing 92 mounted on the loading part 211 detaches from the loading part 211 under gravity, it can avoid contact with the inner wall forming the limiting channel 101, thereby preventing the detachment process of the planar bearing 92 from being hindered.

[0040] Preferably, the fixing component 22 is configured as a pin.

[0041] Preferably, such as Figure 5 As shown, the material handling platform 30 has a front side 31 located below the limiting cylinder 10 and a rear side 32 opposite to the front side 31. The material handling platform 30 is provided with a recess 301 that can be recessed from the outer periphery to the center for a predetermined length, penetrating the front side 31 and the rear side 32. The recess 301 is located in the axial position of the loading part 211. Thus, when the planar bearing 92 is disengaged from the loading part 211 to the front side 31 of the material handling platform 30, the recess 301 is at least partially opposite to the inner ring of the planar bearing 92, so that the operator can insert his hand into the recess 301 to hook the inner ring of the planar bearing 92, thereby facilitating the removal of the planar bearing 92.

[0042] More preferably, the front side 31 is arranged to coincide with the projection of the limiting cylinder 10 on the same horizontal plane, and the material picking platform 30 also forms a limiting space 302 on the front side 31 with at least a portion of the opening facing the limiting channel 101 to communicate with the recess 301, and at least another portion of the opening of the limiting space 302 is arranged to face the recess 301. In addition, the inner diameter of the limiting space 302 is set to gradually increase from the material picking platform 30 to the limiting cylinder 10. In this way, the planar bearing 92 can be confined in the limiting space 302 after it is detached from the loading part 211, and it is difficult for it to continue to detach from the material picking platform 30, thereby ensuring that the planar bearing 92 that has detached from the loading part 211 can be taken out by the operator on the material picking platform 30.

[0043] Those skilled in the art should understand that the embodiments of this application described above and shown in the accompanying drawings are merely examples and do not limit the scope of this application. The advantages of this application have been fully and effectively implemented. The functional and structural principles of this application have been demonstrated and explained in the embodiments, and any variations or modifications can be made to the implementation of this application without departing from the stated principles.
