Description

Technical Field

[0001] The present invention relates to the field of detection technology, and in particular to a bearing outer ring detection device and method. Background Art

[0002] During the bearing production process, the treatment of the bearing outer ring includes two key steps: cleaning and testing. First, the bearing outer ring must be cleaned to remove impurities such as oil, iron filings, and other impurities attached to the surface of the bearing outer ring to ensure that the subsequent testing process is not interfered with. After cleaning, the outer surface of the bearing outer ring must be inspected to identify defects such as cracks on the bearing outer ring through testing equipment, thereby ensuring that the quality of the bearing outer ring meets the use standards.

[0003] After the bearing outer ring is cleaned, it is relocated by a fixture to the corresponding position of the testing equipment to ensure the continuity of the production process. To save costs, the fixture can only move in two perpendicular horizontal directions. When the bearing outer ring is relocated, continuous friction will be generated between the bearing outer ring and the work surface, which may cause wear of the bearing outer ring.

[0028] In some embodiments, based on the bearing outer ring being located on the first turntable and the first detection result being qualified, controlling the bearing outer ring to move along the first direction to the next processing station includes:

At the same time, the sum of the widths of the first avoidance groove and the third avoidance groove is greater than the width of the second avoidance groove. Therefore, when the traverse assembly moves the outer ring of the bearing horizontally, the areas of the two ends of the outer ring of the bearing along the second direction located in the first avoidance groove and the third avoidance groove, respectively, are larger, thereby further reducing the contact area between the outer ring of the bearing and the cleaning station, the first inspection station, and the first turntable, thereby reducing the friction between the outer ring of the bearing and the cleaning station, the first inspection station, and the first turntable during movement, thereby preventing the outer ring of the bearing from wearing due to excessive friction.

[0051] During the bearing production and processing process, the bearing outer ring 80 must first be cleaned, and then multiple bearing outer rings 80 are clamped and moved together by the transverse movement assembly, and the outer surface of the bearing outer ring 80 is inspected. By cleaning and inspecting multiple bearing outer rings 80 at the same time, a continuous assembly line production process is formed, and the inspection efficiency of the bearing outer ring 80 is improved. Because the transverse movement assembly needs to clamp and move the bearing outer rings 80 at different workstations at the same time, in order to save costs, the transverse movement assembly can only move in two perpendicular horizontal directions. However, when the bearing outer ring 80 is transferred, continuous friction will be generated between the bearing outer ring 80 and the cleaning station 11, the first inspection station 21 and the first transfer station 31, which may cause wear of the bearing outer ring 80.

[0052] Example 1:

[0053] In this embodiment, in order to solve the above problems, the present invention provides a bearing outer ring 80 detection device, such as Figure 1 、 Figure 2 、 Figure 3 As shown, the bearing outer ring 80 detection device includes a cleaning component 10, a first detection component 20, a first transfer component 30, a material receiving component 40 and a transverse movement component.

[0054] The cleaning assembly 10 includes a cleaning table 11 and a spray unit 12. The cleaning table 11 is horizontally arranged, with the spray unit 12 positioned above it. When the bearing outer ring 80 is being inspected, it can be placed on the cleaning table 11. The spray unit 12 then sprays cleaning fluid onto the cleaning table 11 to clean the bearing outer ring 80, remove surface impurities, and provide a clean foundation for subsequent inspections.

[0055] The first inspection assembly 20 includes a first inspection platform 21 and a first inspection unit 22. The first inspection platform 21 is connected to the cleaning platform 11 and is arranged horizontally. The first inspection unit 22 is located above the first inspection platform 21. When the bearing outer ring 80 is positioned on the first inspection platform 21, the first inspection unit 22 detects cracks on at least the upper end surface of the bearing outer ring 80. The inner diameter of the bearing outer ring 80 is conical. Therefore, the first end surface of the bearing outer ring 80 with the larger inner diameter faces upward, that is, toward the cleaning assembly 10. This facilitates more thorough cleaning of the inner circumferential surface of the bearing outer ring 80 by the cleaning assembly 10.

[0056] The first transfer assembly 30 includes a first transfer table 31 and a first drive unit 32. The first transfer table 31 is connected to the first inspection table 21, and the first inspection table 21 is arranged horizontally. After the transverse movement assembly moves the bearing outer ring 80 on the first inspection table 21 to the first transfer table 31, it determines whether the bearing outer ring 80 is qualified based on the inspection result of the first inspection unit 22. If qualified, the bearing outer ring 80 is controlled to move along the first direction Q1 by the transverse movement assembly to perform subsequent inspection processes. If unqualified, the first drive unit 32 drives the first transfer table 31 to rotate around the first axis, so that the first transfer table 31 tilts, and the bearing outer ring 80 moves along the second direction Q2 toward the receiving assembly 40. The first direction Q1 is perpendicular to the second direction Q2, and the first direction Q1 is as follows. Figure 3 From right to left, the second direction Q2 is as shown Figure 3 Bottom-up orientation shown.

[0057] The receiving assembly 40 includes a first receiving unit 41. The first receiving unit 41 is located in the second direction Q2 of the first turntable 31. The height of the first receiving unit 41 is lower than that of the first turntable 31. In this way, the first drive unit 32 drives the first turntable 31 to rotate about the first axis. Due to the height difference between the first receiving unit 41 and the first turntable 31, unqualified bearing outer rings 80 can be moved into the first receiving unit 41, thereby facilitating subsequent processing.

[0058] The cleaning station 11, first inspection station 21, and first transfer station 31 are arranged sequentially along a first direction Q1, with the first axis parallel to the first direction Q1. Each outer ring bearing must pass through the cleaning station 11, first inspection station 21, and first transfer station 31 for inspection. The transverse motion assembly can simultaneously drive the movement of multiple outer ring bearings. For example, after one outer ring bearing is cleaned, it moves to the first inspection station 21, while another outer ring bearing moves to the cleaning station 11 for cleaning. The transverse motion assembly synchronizes the movement of outer ring bearings at multiple stations, and the spray unit 12 and first inspection unit 22 operate simultaneously, enabling efficient inspection of multiple bearing outer rings 80.

[0059] like Figure 4As shown, the cleaning station 11, the first inspection station 21, and the first transfer station 31 are each provided with a first avoidance unit 33, which includes a first avoidance groove 331, a second avoidance groove 332, and a third avoidance groove 333. The first avoidance groove 331, the second avoidance groove 332, and the third avoidance groove 333 all extend along the first direction Q1. Thus, during the movement of the outer ring bearing, the first avoidance groove 331, the second avoidance groove 332, and the third avoidance groove 333 can reduce the contact area between the lower end surface of the bearing outer ring 80 and the cleaning station 11, the first inspection station 21, and the first transfer station 31, respectively. At the same time, the second avoidance groove 332 is located between the first avoidance groove 331 and the third avoidance groove 333. The sum of the widths of the first avoidance groove 331 and the third avoidance groove 333 is greater than the width of the second avoidance groove 332. Because the second avoidance groove 332 reduces the area of ​​the bearing outer ring 80 at both ends along the first direction Q1, the sum of the widths of the first avoidance groove 331 and the third avoidance groove 333 is greater than the width of the second avoidance groove 332, and the outer ring bearing is a circular ring. This increases the contact area between the first avoidance groove 331 and the third avoidance groove 333 and the bearing outer ring 80 at both ends along the second direction Q2. This reduces the contact area between the bearing outer ring 80 and the cleaning station 11, the first inspection station 21, and the first transfer station 31, thereby reducing the friction of the traverse assembly moving the bearing outer ring 80 along the first direction Q1.

[0060] In other embodiments, the first detection unit 22 is further used to detect cracks on the circumferential surface of the bearing outer ring 80. That is, the first detection unit 22 is used to detect cracks on the inner circumferential surface and / or the outer circumferential surface of the bearing outer ring 80.

[0061] Furthermore, when the bearing outer ring 80 having a conical inner circumference is located on the first inspection platform 21, the first end face of the bearing outer ring 80 with a larger inner diameter faces upward. Preferably, since the normal direction of the inner circumferential surface of the bearing outer ring 80 faces upward, cracks on the inner circumferential surface are easy to detect, and therefore the first inspection unit 22 is used to detect cracks on the inner circumferential surface of the bearing outer ring 80.

[0062] In other embodiments, Figure 1 As shown, the bearing outer ring 80 detection device further includes a flip assembly 50 , a second detection assembly 60 and a second transfer assembly 70 .

[0063] The flip assembly 50 includes a support platform 51 and a flipping manipulator 52. The support platform 51 is horizontally arranged, with the flipping manipulator 52 located above the support platform 51 and connected to the first transfer platform 31. The support platform 51 provides a placement for the bearing outer ring 80. The flipping manipulator 52 can control the bearing outer ring 80 on the support platform 51 to flip 180°, thereby switching the upper and lower end faces of the bearing outer ring 80, allowing for inspection of both end faces and improving the comprehensiveness of the inspection.

[0064] The second inspection assembly 60 includes a second inspection platform 61 and a second inspection unit 62. The second inspection platform 61 is connected to the support platform 51 and arranged horizontally, with the second inspection unit 62 positioned above it. The second inspection platform 61 is capable of supporting the inverted bearing outer ring 80. Since the first inspection unit 22 inspected the upper end surface of the bearing outer ring 80 and determined it to be qualified, the second inspection unit 62 is required to inspect at least the upper end surface of the bearing outer ring 80 on the second inspection platform 61 for cracks. Specifically, the second end surface of the bearing outer ring 80, with its smaller inner diameter, is inspected. This ensures that both end surfaces of the bearing outer ring 80 are inspected by both the first and second inspection units 22 and 62.

[0065] The second transfer assembly 70 includes a second turntable 71 and a second drive unit 72. The second turntable 71 is connected to the second inspection table 61, and the second turntable 71 is arranged horizontally. The second drive unit 72 is connected to the second turntable 71. The second drive unit 72 controls the second turntable 71 to rotate around the first axis. After the transverse movement assembly moves the bearing outer ring 80 on the second inspection table 61 to the second turntable 71, it determines whether the bearing outer ring 80 is qualified based on the inspection result of the second inspection unit 62. If qualified, the bearing outer ring 80 is controlled by the transverse movement assembly to move along the first direction Q1 for subsequent testing procedures. If unqualified, the second turntable 71 is driven to rotate around the first axis by the second drive unit 72, so that the second turntable 71 tilts, and the bearing outer ring 80 slides along the second direction Q2 toward the receiving assembly 40.

[0066] The receiving assembly 40 also includes a second receiving unit 42, which is located in the second direction Q2 of the second turntable 71. The height of the second receiving unit 42 is lower than that of the second turntable 71. The first turntable 31, support table 51, second inspection table 61, and second turntable 71 are arranged in sequence along the first direction Q1. A first avoidance unit 33 is provided on each of the first turntable 31, support table 51, second inspection table 61, and second turntable 71. Each outer ring bearing is inspected sequentially through the cleaning table 11, first inspection table 21, first turntable 31, support table 51, second inspection table 61, and second turntable 71. If the second inspection table 61 detects that the bearing outer ring 80 is unqualified, the second turntable 71 and second drive unit 72 move the bearing outer ring 80 to the second receiving unit 42, thereby sorting the qualified and unqualified bearing outer rings 80 and ensuring that qualified bearing outer rings 80 are put into use.

[0067] In other embodiments, when a bearing outer ring 80 with a conical inner circumference is positioned on the first inspection platform 21, the first end surface of the bearing outer ring 80 with a larger inner diameter faces upward, and the first end surface is inspected while the inner circumference of the bearing outer ring 80 is inspected simultaneously. When a bearing outer ring 80 with a conical inner circumference is positioned on the second inspection platform 61, the second end surface of the bearing outer ring 80 with a smaller inner diameter faces upward, and the second end surface is inspected while the outer circumference of the bearing outer ring 80 is inspected simultaneously. This ensures that the surface of the bearing outer ring 80 is fully inspected.

[0068] Furthermore, if Figure 3 As shown, a second avoidance unit 34 is provided on the upper surface of the first turntable 31 near the first material receiving unit 41. The second avoidance unit 34 includes a fourth avoidance groove 341. The fourth avoidance groove 341 extends along the second direction Q2 and is located on the side of the first avoidance groove 331 away from the second avoidance groove 332. When the first detection unit 22 detects that the upper end surface of the bearing outer ring 80 is unqualified and the bearing outer ring 80 moves onto the first turntable 31, the first driving unit 32 drives the first turntable 31 to tilt toward the first material receiving unit 41, and the fourth avoidance groove 341 extends along the second direction Q2. The fourth avoidance groove 341 reduces the contact area between the bearing outer ring 80 and the first turntable 31, thereby reducing the friction between the bearing outer ring 80 and the first turntable 31, so that the bearing outer ring 80 can slide better to the first material receiving assembly 40. At the same time, because the sliding direction of the bearing outer ring 80 lacks constraint guidance, and due to the setting of the fourth avoidance groove 341, when the bearing outer ring 80 tends to slide along the first direction Q1, the shape of the fourth avoidance groove 341 is a long pit, which will generate resistance with the fourth avoidance groove 341 and the solid part of the first turntable 31, thereby increasing the resistance of the bearing outer ring 80 along the first direction Q1, and further reducing the possibility of the sliding direction of the bearing outer ring 80 shifting during the process of sliding to the first material receiving component 40.

[0069] A second avoidance unit 34 is provided on the upper surface of the second turntable 71 in an area near the second receiving unit 42. When the second detection unit 62 detects that the lower end surface of the bearing outer ring 80 is unqualified and the bearing outer ring 80 moves onto the second turntable 71, the second drive unit 72 drives the second turntable 71 to tilt toward the second receiving unit 42. The fourth avoidance groove 341 reduces the contact area between the bearing outer ring 80 and the second turntable 71, thereby reducing the friction between the bearing outer ring 80 and the second turntable 71, allowing the bearing outer ring 80 to slide more smoothly to the second receiving assembly 40. At the same time, the possibility of the sliding direction of the bearing outer ring 80 shifting during the sliding process of the bearing outer ring 80 to the second receiving assembly 40 is reduced.

[0070] Furthermore, if Figure 3As shown, the widths of the first, second, and third evacuation grooves 331, 332, and 333 are all greater than the width of the fourth evacuation groove 341. Thus, the first, second, and third evacuation grooves 331, 332, and 333 effectively reduce the contact area between the bearing outer ring 80 and the cleaning station 11, the first inspection station 21, the first turntable 31, the support station 51, the second inspection station 61, and the second turntable 71 during movement in the first direction Q1. The fourth evacuation groove 341 reduces the contact area between the first turntable 31 or the second turntable 71 and the bearing outer ring 80, thereby reducing friction between the bearing outer ring 80 and the first turntable 31 when the bearing outer ring 80 slides toward the receiving assembly 40. If the fourth evacuation groove 341 were wider, the bearing outer ring 80 would lack restraint and guidance when sliding in the second direction Q2, potentially causing portions of the bearing outer ring 80 to fall into the fourth evacuation groove 341, resulting in the bearing outer ring 80 becoming stuck. Therefore, the width of the fourth avoidance groove 341 is set to be smaller, which can not only reduce the friction between the bearing outer ring 80 and the first turntable 31 or the second turntable 71, but also prevent part of the bearing outer ring 80 from falling into the fourth avoidance groove 341 and getting stuck.

[0071] Furthermore, if Figure 3 As shown, there are multiple fourth avoidance grooves 341 in each second avoidance unit 34. The distance between the first avoidance groove 331 and the second avoidance groove 332 is greater than the distance between two adjacent fourth avoidance grooves 341. The distance between the second avoidance groove 332 and the third avoidance groove 333 is greater than the distance between two adjacent fourth avoidance grooves 341. In this way, the direction of the bearing outer ring 80 sliding toward the material receiving assembly 40 is restricted by the relatively dense and smaller fourth avoidance grooves 341, and the friction between the bearing outer ring 80 and the first turntable 31 and the second turntable 71 is reduced. This allows the unqualified bearing outer ring 80 to slide accurately into the material receiving assembly 40.

[0072] Example 2:

[0073] In this embodiment, the present application provides a bearing outer ring 80 detection method applied to the bearing outer ring 80 detection method in embodiment 1. Figure 6 As shown, the bearing outer ring 80 detection method includes steps S10 to S60. Steps S10 to S60 are described in detail below:

[0074] In step S10, the outer ring 80 of the bearing is cleaned to remove the iron filings and oil stains on the surface of the outer ring 80 of the bearing, so as to avoid the interference of the iron filings and oil stains with the subsequent detection process, thereby ensuring the accuracy of the subsequent detection results and achieving the effect of improving the detection reliability.

[0075] In step S20, upon completion of cleaning of the bearing outer ring 80, the traverse assembly controls the bearing outer ring 80 to move along the first direction Q1 to the first inspection station 21. This achieves an orderly connection between the cleaning process and the inspection process, ensuring the continuity of the inspection.

[0076] In step S30, with the bearing outer ring 80 positioned on the first inspection station 21, a first crack inspection is performed on the upper end surface of the bearing outer ring 80, i.e., the first end surface of the bearing outer ring 80 with the larger inner diameter faces upward. This allows for timely detection of cracks on the first end surface of the bearing outer ring 80, and also for simultaneous inspection of the inner circumference of the bearing outer ring 80. This allows for early detection of unqualified bearing outer rings 80, preventing them from entering subsequent processes and ensuring the quality of the bearing outer ring 80.

[0077] In step S40, upon completion of the first crack detection, the bearing outer ring 80 is controlled to move along the first direction Q1 to the first turntable 31, and a first crack detection result is obtained to facilitate subsequent classification and processing based on the detection result. When the bearing outer ring 80 is located on the first turntable 31, the cleaning station 11, or the first inspection station 21, a portion of the lower end surface of the bearing outer ring 80 proximate the first receiving assembly 40 is located above the first avoidance groove 331, and a portion of the lower end surface of the bearing outer ring 80 distal from the first receiving assembly 41 is located above the third avoidance groove 333. This increases the area of ​​the bearing outer ring 80 above the first avoidance groove 331 or the third avoidance groove 333 compared to the area of ​​the bearing outer ring 80 above the centrally located second avoidance groove 332. This further reduces the contact area between the bearing outer ring 80 and the first turntable 31, the cleaning station 11, and the first inspection station 21, thereby reducing friction between the bearing outer ring 80 and the first turntable 31.

[0078] In step S50, based on the bearing outer ring 80 being located on the first transfer table 31 and the first inspection result being qualified, the bearing outer ring 80 is controlled to move along the first direction Q1 to the next processing station. This ensures the continuity of the processing steps, improves overall processing efficiency, and ensures that qualified products can smoothly enter the next stage.

[0079] After step S40 is completed, either step S50 or step S60 is executed. In step S60, based on the bearing outer ring 80 being located on the first transfer table 31 and the first test result being unqualified, the first transfer table 31 is controlled to rotate until the bearing outer ring 80 falls onto the first receiving unit 41. This automatically collects unqualified products, preventing them from mixing with qualified products. This facilitates centralized processing of unqualified products, resolves the difficulty of sorting unqualified products, and achieves the effect of automatically sorting unqualified products.

[0080] Furthermore, when the bearing outer ring 80 is located on the first turntable 31, the arc portion of the outer circumference of the bearing outer ring 80 near the first material receiving unit 41 is misaligned with the first avoidance groove 331. With the inner circumference positioned above the first avoidance groove 331 and the outer circumference misaligned with the first avoidance groove 331, the first turntable 31 can smoothly slide into the material receiving assembly 40 when rotating about the first axis, thereby preventing the arc portion of the bearing outer ring 80 near the first material receiving unit 41 from being located above the first avoidance groove 331, which could cause the bearing outer ring 80 to partially fall into the first avoidance groove 331 when sliding, thereby causing the bearing outer ring 80 to become stuck.

[0081] Furthermore, step S50 includes steps S51 to S57. The method for detecting the bearing outer ring 80 sequentially performs steps S10, S20, S30, S40, S51, S52, S53, S54, S55, S56, or S57. Steps S51 to S57 are described in detail below:

[0082] In step S51, based on the bearing outer ring 80 being located on the first transfer platform 31 and the first inspection result being qualified, the transverse movement assembly controls the bearing outer ring 80 to move along the first direction Q1 to the support platform 51. By moving the bearing outer ring 80 to the support platform 51, a stable support base is provided for the subsequent flipping operation, preventing the bearing outer ring 80 from shaking or shifting during the flipping process.

[0083] In step S52, with the bearing outer ring 80 positioned on the support platform 51, the bearing outer ring 80 is flipped 180°. This positions the end face of the bearing outer ring 80, which was originally facing downward, upward, facilitating inspection of the flipped end face. This allows for comprehensive inspection of both end faces of the bearing outer ring 80, preventing the possibility of missing cracks by inspecting only one end face, ultimately improving the integrity and accuracy of product inspection.

[0084] In step S53, upon completion of the flipping of the bearing outer ring 80, the bearing outer ring 80 is controlled to move along the first direction Q1 to the second testing platform 61. By moving the bearing outer ring 80 to the second testing platform 61 after the flipping is complete, an orderly transition between the flipping process and the second crack detection process is achieved, ensuring the smooth progress of the detection work, maintaining the stability of the testing environment, and achieving a smooth transition between the processes.

[0085] In step S54, with the bearing outer ring 80 positioned on the second inspection station 61, a second crack inspection is performed on the upper end surface of the bearing outer ring 80. Simultaneously, the outer diameter surface of the bearing outer ring 80 is inspected. This ensures a comprehensive inspection of both end surfaces and the outer surface of the bearing outer ring 80, preventing missed inspections and ultimately ensuring product quality.

[0086] In step S55, based on the completion of the second crack detection, the bearing outer ring 80 is controlled to move along the first direction Q1 to the second turntable 71, and a second detection result of the second crack detection is obtained. When the bearing outer ring 80 is located on the second turntable 71 or the support platform 51, the portion of the lower end surface of the bearing outer ring 80 proximate the second receiving assembly 40 is located above the first avoidance groove 331, and the portion of the lower end surface of the bearing outer ring 80 distal from the second receiving unit 42 is located above the third avoidance groove 333. This increases the area of ​​the bearing outer ring 80 located above the first avoidance groove 331 or the third avoidance groove 333 compared to the area of ​​the bearing outer ring 80 located above the central second avoidance groove 332. This further reduces the contact area between the bearing outer ring 80 and the second turntable 71 and the support platform 51, thereby reducing friction between the bearing outer ring 80 and the second turntable 71 and the support platform 51. When the bearing outer ring 80 is located on the second turntable 71, the arc of the outer circumference of the bearing outer ring 80 close to the second material receiving unit 42 is misaligned with the first avoidance groove 331. Figure 5 As shown, the arc line of the outer circumferential contour of the bearing outer ring 80 close to the second material receiving unit 42 is located in the physical part of the second turntable 71 and the first avoidance groove 331 close to the second material receiving component 40, so that when the bearing outer ring 80 is unqualified, the second turntable 71 is tilted and rotated, and the bearing outer ring 80 can slide smoothly into the second material receiving component 40.

[0087] In step S56, based on the bearing outer ring 80 being located on the second transfer table 71 and the second inspection result being qualified, the bearing outer ring 80 is controlled to move along the first direction Q1 to the next processing station. This ensures the orderly flow of qualified bearing outer rings 80 and the continuity of the processing steps, thereby improving overall processing efficiency and ensuring that qualified products can smoothly enter the next stage.

[0088] After step S55 is completed, either step S56 or step S57 is executed. In step S57, based on the bearing outer ring 80 being located on the second turntable 71 and the second inspection result being unqualified, the second turntable 71 is controlled to rotate until the bearing outer ring 80 falls into the second receiving unit 42. This automatically collects the unqualified bearing outer rings 80, preventing them from being mixed with qualified bearing outer rings 80 and facilitating centralized processing of the unqualified bearing outer rings 80.

[0089] Furthermore, the inner circumferential wall of the bearing outer ring 80 is tapered. The bearing outer ring 80 has a first end face and a second end face. The inner diameter of the first end face is larger than the inner diameter of the second end face. When the bearing outer ring 80 is located on the first turntable 31, the second end face of the bearing outer ring 80 is set downward. The first end face is as follows Figure 3 The second end face is as shown in FIG. Figure 3The upper side of the bearing outer ring 80 is shown on the second turntable 71. Since the bearing outer ring 80 needs to be cleaned before passing through the support seat, the upper side of the first end face of the bearing outer ring 80 can more effectively clean the impurities on the surface, thereby facilitating the detection by the first detection unit 22 and ensuring the accuracy of the detection results.

[0090] Furthermore, if Figure 4 As shown, since the inner circumferential wall of the bearing outer ring 80 is tapered, when the bearing outer ring 80 is located on the first turntable 31, the end face of the bearing outer ring 80 with the larger inner diameter faces upward. This will result in the inner circumferential contour of the bearing outer ring 80 being at an obtuse angle to the first turntable 31 when the first turntable 31 first begins to tilt, thereby making it easy for it to get stuck with the physical portion of the first turntable 31 located in the third avoidance groove 333. Therefore, in the present application, the inner circumferential contour of the bearing outer ring 80 being at an arc portion away from the first material receiving unit 41 is misaligned with the third avoidance groove 333, that is, the inner circumferential contour of the bearing outer ring 80 being at an arc portion away from the first material receiving unit 41 is located on the first turntable 31, thereby avoiding the possibility of the bearing outer ring 80 and the first turntable 31 getting stuck due to insufficient sliding force when the first turntable 31 first begins to tilt.

[0091] When the bearing outer ring 80 is located on the second turntable 71, Figure 5 As shown, the portion of the inner circumference of the bearing outer ring 80 that is away from the second receiving unit 42 is located above the third avoidance groove 333. The portion of the inner circumference of the bearing outer ring 80 that is away from the second receiving unit 42 forms an acute angle with the second turntable 71. Even if the initial sliding force is insufficient, the portion of the inner circumference of the bearing outer ring 80 that is close to the second receiving unit 42 and the second turntable 71 affect the bearing outer ring 80 and cause it to slide toward the first receiving assembly 40. Therefore, the portion of the inner circumference of the bearing outer ring 80 that is away from the second receiving unit 42 is located above the third avoidance groove 333, reducing the friction force on the bearing outer ring 80 moving in the first direction Q1.

[0092] In other embodiments, the cleaning table 11, the first inspection table 21, the first turntable 31, the support table 51, the second inspection table 61 and the second turntable 71 are respectively provided with a plurality of second avoidance grooves 332, thereby further reducing the friction of the cleaning table 11, the first inspection table 21, the first turntable 31, the support table 51, the second inspection table 61 and the second turntable 71, so that the outer ring 80 of the bearing can move better along the first direction Q1, thereby reducing the wear of the outer ring 80 of the bearing.
