[0002] In automated wafer testing equipment, a row of rollers is typically installed on opposite sides of the conveyor to place the wafer test fixture onto the rollers for transport. In existing technology, the rollers rotate easily; however, if multiple rollers are installed at a slight angle, the wafer test fixture can easily slip when placed on them. Therefore, there is an urgent need to design rollers that prevent wafer test fixtures from slipping. Utility Model Content

[0003] One objective of this invention is to provide a damping wheel to solve the technical problem that wafer testing fixtures tend to slip when placed on rollers in the prior art.

[0004] A further objective of this invention is to further increase the friction between the damping wheel and the wafer testing fixture.

[0005] Another objective of this invention is to provide a conveying device having the aforementioned damping wheel.

[0006] Specifically, this utility model provides a damping wheel, comprising:

[0007] The fastener includes an interconnected shaft and a limiting portion, wherein the limiting portion has at least one through hole arranged radially therein;

[0008] A rotating wheel is sleeved on the outside of the fixing member and has a first inner wall, which is arranged opposite to the outer wall of the limiting part.

[0009] At least one damping component, each damping component being disposed within one of the through holes, and comprising an elastic element and two friction rods, the elastic element being arranged along the extension direction of the through hole, and the two friction rods being respectively arranged at both ends of the elastic element, with the ends abutting against the first inner wall.

[0010] Optionally, each of the friction rods includes a first part and a second part connected to each other, the first part passing through the interior of the elastic member, one end of the second part forming a stepped surface with the first part, the stepped surface abutting against the elastic member, and the other end of the second part abutting against the first inner wall.

[0011] Optionally, both the first portion and the second portion are cylindrical.

[0012] Optionally, the end of the first portion away from the second portion is pointed.

[0013] Optionally, the outer wall of the rotating wheel is provided with at least one groove arranged circumferentially thereon, and the damping wheel further includes:

[0014] At least one damping ring, each of the damping rings being mounted within one of the grooves and partially protruding from the groove.

[0015] Optionally, the number of damping rings is multiple, and the multiple damping rings are arranged at intervals.

[0016] Optionally, the rotating wheel further has a second inner wall, the shaft includes a first shaft and a second shaft connected to each other, the first shaft is connected to the limiting portion, and the second shaft is disposed on the side of the first shaft away from the limiting portion for connection to the target component; the damping wheel further includes:

[0017] The bearing is sleeved on the first shaft, and its outer wall abuts against the second inner wall of the rotating wheel;

[0018] A snap ring is disposed on the outside of the bearing and engages with the rotating wheel;

[0019] A retaining ring is fitted onto the first shaft and positioned on the outside of the bearing.

[0020] Optionally, the limiting portion is provided with at least one operating hole extending along its axial direction, the operating hole being operated by an operating tool to tighten the fastener.

[0023] In this invention, the fixing component includes an interconnected shaft and a limiting portion. The limiting portion has at least one through hole arranged radially therein. The rotating wheel is sleeved on the outside of the fixing component and has a first inner wall, which is arranged opposite to the outer wall of the limiting portion. Each damping component is disposed in a through hole and includes an elastic element and two friction rods. The elastic element is arranged along the extension direction of the through hole, and the two friction rods are respectively arranged at both ends of the elastic element, with their ends abutting against the first inner wall. This effectively uses the elastic force of the elastic element to make the friction rods at both ends simultaneously press against the rotating wheel, applying a certain pressure to the rotating wheel. This forces the rotating wheel to overcome a certain frictional force to rotate, preventing the rotating wheel from rotating easily and causing the wafer testing fixture to slip.

[0024] Furthermore, in this invention, the outer wall of the rotating wheel is provided with at least one groove arranged along its circumference, and the damping wheel also includes at least one damping ring.

Figure 3 This is a schematic cross-sectional view of a damping wheel 100 according to an embodiment of the present invention. Figure 4 This is a schematic exploded view of a damping wheel 100 according to an embodiment of the present invention. Figure 5 yes Figure 1 The diagram shows a schematic installation of the damping component 30 and the fixing member 10 of the damping wheel 100. Figure 6 yes Figure 1 A schematic structural diagram of the damping component 30 of the damping wheel 100 shown. Figure 7 yes Figure 1 A schematic cross-sectional view of the rotating wheel 20 of the damping wheel 100 shown. Figures 1 to 7 As shown, in a preferred embodiment, the damping wheel 100 includes a fixing member 10, a rotating wheel 20, and at least one damping component 30. The fixing member 10 includes an interconnected shaft 11 and a limiting portion 12, the limiting portion 12 having at least one through hole 121 arranged radially therein. The rotating wheel 20 is sleeved on the outside of the fixing member 10 and has a first inner wall 21, which is arranged opposite to the outer wall of the limiting portion 12. Each damping component 30 is disposed within a through hole 121 and includes an elastic member 31 and two friction rods 32. The elastic member 31 is arranged along the extending direction of the through hole 121, and the two friction rods 32 are respectively arranged at both ends of the elastic member 31, with their ends abutting against the first inner wall 21.

[0042] This embodiment utilizes the elastic force of the elastic element 31 to simultaneously press the friction rods 32 at both ends against the rotating wheel 20, applying a certain pressure to the rotating wheel 20. This forces the rotating wheel 20 to overcome a certain frictional force to rotate, preventing the rotating wheel 20 from rotating too easily and causing the wafer testing fixture to slip. In addition, the damping wheel 100 in this embodiment is small in size, has low damping, and is stable and reliable.

[0043] In some embodiments, the elastic element 31 is a spring. The spring needs to ensure that the friction rod 32 presses against the rotating wheel 20, applying a certain pressure to the rotating wheel 20, but not blocking the rotating wheel 20 completely and affecting its rotation. In other embodiments, the elastic element 31 can also be other components with the same elastic properties as a spring.

[0044] In some embodiments, each friction rod 32 includes a first part 321 and a second part 322 connected to each other. The first part 321 passes through the interior of the elastic member 31. One end of the second part 322 forms a stepped surface with the first part 321 and the stepped surface abuts against the elastic member 31. The other end of the second part 322 abuts against the first inner wall 21.

[0045] This embodiment achieves the engagement of the friction rod 32 and the elastic member 31 by inserting the first part 321 of the friction rod 32 through the interior of the elastic member 31.

[0046] In some embodiments, both the first portion 321 and the second portion 322 are cylindrical. In other embodiments, the shapes of the first portion 321 and the second portion 322 can be determined according to specific design requirements.

[0047] In some embodiments, the end of the first portion 321 away from the second portion 322 is pointed, which makes it easier for the first portion 321 to be inserted into the interior of the elastic member 31.

[0048] In some embodiments, the outer wall of the rotating wheel 20 is provided with at least one groove 23 arranged circumferentially thereon, and the damping wheel 100 further includes at least one damping ring 40, each damping ring 40 being installed in a groove 23 and partially protruding out of the groove 23.

[0049] This embodiment is designed with a damping ring 40, which can increase the friction between the rotating wheel 20 and the wafer test fixture, and prevent the wafer test fixture from slipping.

[0050] In some embodiments, the number of damping rings 40 is multiple, and the multiple damping rings 40 are arranged at intervals. In this embodiment, the number of damping rings 40 is two.

[0051] In some embodiments, the rotating wheel 20 further has a second inner wall 22, and the shaft 11 includes a first shaft 111 and a second shaft 112 connected to each other. The first shaft 111 is connected to the limiting portion 12, and the second shaft 112 is disposed on the side of the first shaft 111 away from the limiting portion 12 for connection with the target component. The damping wheel 100 also includes a bearing 50, a retaining ring 60, and a retaining ring 70. The bearing 50 is sleeved on the first shaft 111, and its outer wall abuts against the second inner wall 22 of the rotating wheel 20. The retaining ring 60 is disposed on the outside of the bearing 50 and engages with the rotating wheel 20. The retaining ring 70 is sleeved on the first shaft 111 and is disposed on the outside of the bearing 50.

[0052] In some embodiments, the second inner wall 22 of the rotating wheel 20 is provided with a snap-fit ​​groove 24 on the side away from the first inner wall 21, and the snap-fit ​​spring 60 is snapped into the snap-fit ​​groove 24.

[0053] In some embodiments, the limiting portion 12 is provided with a plurality of operating holes 122 extending along its axial direction, and the plurality of operating holes 122 are arranged in a straight line. Here, the operating holes 122 are arranged parallel to the shaft body 11. When the damping wheel 100 is installed, the operating tool is pressed against the operating hole 122, and the fixing member 10 is rotated, thereby tightening the second shaft body 112 with the target member.

[0054] In this embodiment, the friction rod 32 is made of polyetheretherketone (PEEK). In other embodiments, the friction rod 32 may be made of other materials, depending on design requirements.

[0055] This embodiment also provides a conveying device, which includes the damping wheel 100 of any of the above embodiments. Details regarding the damping wheel 100 are not provided here.

[0056] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention.
