Description

Technical Field

[0001] The present application relates to the technical field of automated production lines, and in particular to a workpiece adjustment device and detection equipment. Background Art

[0002] Glass cover plates are widely used in various electronic devices such as smartphones, tablets, smart watches, etc., and quality control during their manufacturing and testing is crucial. Glass cover plates usually have a flat surface on one side and a curved surface on the other side. The shape of the curved surface is relatively complex, and the curved surface usually needs to be facing up during testing. Since glass cover plates are usually made of transparent materials, the curved surface facing up is not only convenient for detecting the curved surface itself, but also for detecting the flat surface on the back through the transparent material. On the contrary, if the flat surface faces up, it is not convenient to detect the curved surface on the back, especially the curved surface. Therefore, before the inspection station, the glass cover plate needs to be turned over so that the curved surface faces up.

[0003] Traditional solutions have various structural designs and methods for flipping glass cover plates, but there are problems with stability and precision during the flipping process and subsequent transportation.

[0004] BACKGROUND OF THE PRESENT APPLICATION The above information disclosed is only for understanding the background of the concept of the present application and may contain information that does not constitute the prior art. Summary of the invention

[0005] Based on this, in order to solve the above problems, it is necessary to provide a workpiece adjustment device.

[0006] The present application provides a workpiece adjustment device, which includes:

[0007] A first conveying mechanism, the first conveying mechanism comprising a first frame and a first conveying assembly disposed on the first frame, wherein a top surface of the first conveying assembly is used to receive a first surface of a workpiece and convey the workpiece along a first direction;

[0008] a second conveying mechanism, the second conveying mechanism comprising a second frame and a second conveying assembly disposed on the second frame, the top surface of the second conveying assembly being used to receive the second surface of the workpiece and convey the workpiece along a second direction, the second surface being disposed opposite to the first surface, and the top surface of the second conveying assembly being higher in height than the top surface of the first conveying assembly; and

[0009] A flipping mechanism, the flipping mechanism includes a rotating shaft and an adsorption component connected to the outer circumferential surface of the rotating shaft, the adsorption component is used to adsorb the workpiece, the rotating shaft is used to drive the adsorption component to rotate to realize the flipping of the workpiece, and the adsorption component can be rotated to a first position and a second position driven by the rotating shaft; when the adsorption component is in the first position, the adsorption component is located above the workpiece of the first conveying component and is used to adsorb the second surface of the workpiece; when the adsorption component is in the second position, the top surface of the second conveying component contacts the second surface of the workpiece, the adsorption component is located below the workpiece, and the side of the adsorption component close to the workpiece is flush with the top surface of the second conveying component and releases the workpiece.

[0010] The present application also provides a detection device, which includes an optical detection device and a workpiece adjustment device as described in any of the above embodiments, wherein the optical detection device is used to detect the workpiece.

[0011] The above workpiece adjustment device and detection equipment have at least the following beneficial effects:

[0012] First, efficient and accurate flipping operation: This device is particularly suitable for workpieces that require high-precision inspection, such as glass cover plates. Through the flipping operation, the curved surface is facing upward, which is convenient for detecting the curved surface and the plane of the back surface, thereby improving the accuracy and efficiency of the inspection. By moving the adsorption component from the first position to the second position, the workpiece can be efficiently and accurately flipped. When the workpiece is on the first conveying component, its first side faces downward; after the adsorption component is flipped, when the workpiece is transferred to the second conveying component, the second side faces downward. This design ensures the stability and accuracy of the workpiece during the flipping process, and avoids the problem of offset or misalignment that may occur during the flipping process.

[0013] Second, the workpiece is placed stably: in the second position after the flip is completed, the top surface of the second conveying component is in contact with the second surface of the workpiece, and the adsorption component is located below the workpiece. At this time, the side of the adsorption component close to the workpiece is also flush with the top surface of the second conveying component, so that the workpiece can be placed accurately and stably on the second conveying component, ensuring the stable placement of the workpiece and avoiding tilting or instability.

[0014] Third, the automatic release mechanism: After the adsorption component places the workpiece steadily on the second conveying component, it will automatically release the workpiece and stop adsorption. This automatic release mechanism simplifies the operation steps, improves the efficiency of the turning and conveying process, and reduces the need for human intervention.

[0015] Fourth, reasonable height difference design: It is understandable that the workpiece and the adsorption component both have a certain thickness. If the top surfaces of the first conveying component and the second conveying component are in the same plane, it is difficult to meet the requirements of the adsorption component to pick up the workpiece in parallel and place the workpiece in parallel. If the adsorption component in the first position is rotated to the top of the first conveying component and is exactly parallel to the workpiece, since both the workpiece and the adsorption component have a certain thickness, the adsorption component and the workpiece in the second position cannot be parallel to the top surface of the second conveying component. However, the present application specifically designs the top surface of the second conveying component to be higher than the top surface of the first conveying component in the height direction. This height difference design helps to smoothly carry out the flipping operation, so that the adsorption component in the second position is flush with the top surface of the second conveying component, and the second surface of the workpiece is exactly in parallel contact with the top surface of the second conveying component. The design is realized, which further improves the stability and accuracy of the flipping and transfer of the workpiece.

[0016] To sum up, the workpiece adjustment device provided in the present application solves the stability and precision problems existing in the prior art through reasonable structural design and height difference setting, significantly improves the efficiency and reliability of the workpiece flipping and conveying process, and is particularly suitable for workpiece flipping operations that require high-precision detection.

DETAILED DESCRIPTION

[0028] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0029] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5In some embodiments, the present application provides a workpiece adjustment device 10, which includes a first conveying mechanism 100, a second conveying mechanism 200, and a flipping mechanism 300. The first conveying mechanism 100 includes a first frame 110 and a first conveying assembly 120 disposed on the first frame 110, the top surface of the first conveying assembly 120 is used to receive the first surface 21 of the workpiece 20, and convey the workpiece 20 along the first direction; the second conveying mechanism 200 includes a second frame 210 and a second conveying assembly 220 disposed on the second frame 210, the top surface of the second conveying assembly 220 is used to receive the second surface 22 of the workpiece 20, and convey the workpiece 20 along the second direction, and the second surface 22 is disposed opposite to the first surface 21. The top surface of the second conveying component 220 is higher than the top surface of the first conveying component 120 in the height direction; the flipping mechanism 300 includes a rotating shaft 310 and an adsorption component 320 connected to the outer circumferential surface of the rotating shaft 310, the adsorption component 320 is used to adsorb the workpiece 20, the rotating shaft 310 is used to drive the adsorption component 320 to rotate to realize the flipping of the workpiece 20, and the adsorption component 320 can be rotated to a first position and a second position driven by the rotating shaft 310; when the adsorption component 320 is in the first position, the adsorption component 320 is located above the workpiece 20 of the first conveying component 120 and is used to adsorb the second surface 22 of the workpiece 20; when the adsorption component 320 is in the second position, the top surface of the second conveying component 220 contacts the second surface 22 of the workpiece 20, the adsorption component 320 is located below the workpiece 20, and the side of the adsorption component 320 close to the workpiece 20 is flush with the top surface of the second conveying component 220 and releases the workpiece 20. The workpiece 20 may include but is not limited to a glass cover plate and the like.

[0030] The workpiece adjustment device 10 has at least the following beneficial effects:

[0031] First, efficient and accurate flipping operation: This device is particularly suitable for workpieces 20 that require high-precision inspection, such as glass cover plates. Through the flipping operation, the curved surface is facing upward, which is convenient for inspecting the curved surface and the plane of the back surface, thereby improving the accuracy and efficiency of the inspection. By moving the adsorption component 320 from the first position to the second position, efficient and accurate flipping of the workpiece 20 can be achieved. When the workpiece 20 is on the first conveying component 120, its first surface 21 faces downward; after the adsorption component 320 is flipped, when the workpiece 20 is transferred to the second conveying component 220, the second surface 22 faces downward. This design ensures the stability and accuracy of the workpiece 20 during the flipping process, and avoids the problem of offset or misalignment that may occur during the flipping process.

[0032] Second, the workpiece 20 is placed stably: in the second position after the flipping is completed, the top surface of the second conveying assembly 220 is just in contact with the second surface 22 of the workpiece 20, and the adsorption assembly 320 is located below the workpiece 20. At this time, the side of the adsorption assembly 320 close to the workpiece 20 is also just flush with the top surface of the second conveying assembly 220, so that the workpiece 20 can be accurately and stably placed on the second conveying assembly 220, ensuring the stable placement of the workpiece 20 and avoiding tilting or instability.

[0033] Third, the automatic release mechanism: after the adsorption component 320 stably places the workpiece 20 on the second conveying component 220, it will automatically release the workpiece 20 and stop adsorbing. This automatic release mechanism simplifies the operation steps, improves the efficiency of the turning and conveying process, and reduces the necessity of human intervention.

[0034] Fourth, reasonable height difference design: It can be understood that the workpiece 20 and the adsorption assembly 320 both have a certain thickness. If the top surfaces of the first conveying assembly 120 and the second conveying assembly 220 are in the same plane, it is difficult to satisfy the adsorption assembly 320 to pick up the workpiece 20 in parallel and place the workpiece 20 in parallel. If the adsorption assembly 320 in the first position rotates to the top of the first conveying assembly 120 and is just parallel to the workpiece 20, since the workpiece 20 and the adsorption assembly 320 both have a certain thickness, the adsorption assembly 320 and the workpiece 20 in the second position cannot be parallel to the top surface of the second conveying assembly 220. However, the present application specifically designs that the top surface of the second conveying assembly 220 is higher than the top surface of the first conveying assembly 120 in the height direction. This height difference design helps the smooth flipping operation, so that the adsorption assembly 320 in the second position is flush with the top surface of the second conveying assembly 220, and the second surface 22 of the workpiece 20 is just parallel to the top surface of the second conveying assembly 220. The design is realized, which further improves the stability and accuracy of the flipping and transfer of the workpiece 20.

[0035] To sum up, the workpiece adjustment device 10 provided in the present application solves the stability and precision problems existing in the prior art through reasonable structural design and height difference setting, significantly improves the efficiency and reliability of the workpiece 20 flipping and conveying process, and is particularly suitable for workpiece 20 flipping operations that require high-precision detection.

[0036] See also Figure 4 and Figure 5In some embodiments, the workpiece adjustment device 10 further includes an intercepting member 400, which is disposed on the first frame 110 and located at one end of the first conveying assembly 120 close to the second conveying assembly 220. The intercepting member 400 is used to intercept the workpiece 20 on the first conveying assembly 120 to limit the workpiece 20 below the adsorption assembly 320 in the first position. The provision of the intercepting member 400 ensures that the workpiece 20 can accurately stay at a predetermined position of the first conveying assembly 120, that is, below the adsorption assembly 320 when it is in the first position. During the conveying process, the workpiece 20 may slide or deflect due to inertia or other external forces, and the intercepting member 400 of this embodiment can effectively prevent the workpiece 20 from accidentally falling off or sliding out of the conveying assembly during the conveying process. This precise positioning avoids the movement or deflection of the workpiece 20 during the conveying process, and ensures that the adsorption assembly 320 can accurately adsorb the workpiece 20, thereby improving the accuracy and stability of the flipping operation. It is understandable that the intercepting member 400 can be adjusted in structure and quantity according to the size of the workpiece 20, ensuring that workpieces 20 of different sizes can be accurately positioned and intercepted, thereby improving the applicability and flexibility of the device. By adding the intercepting member 400, the accuracy, stability and safety of the workpiece adjustment device 10 are further improved, the operation process is simplified, and it is applicable to workpieces 20 of various sizes, which significantly improves the overall work efficiency and reliability.

[0037] Specifically, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, in some embodiments, the first conveying assembly 120 includes a plurality of mutually parallel first conveying shafts 121 disposed on the first frame 110, the plurality of first conveying shafts 121 are aligned and spaced along the first direction, a first gap 122 is formed between any two adjacent first conveying shafts 121, the axial direction of any first conveying shaft 121 is perpendicular to the first direction, the outer peripheral surfaces of the plurality of first conveying shafts 121 are used to receive the first surface 21 of the workpiece 20, and the plurality of first conveying shafts 121 can rotate to drive the workpiece 20 to move along the first direction until the workpiece 20 is intercepted by the intercepting member 400. The plurality of parallel first conveying shafts 121 can evenly carry and convey the workpiece 20, ensure the stability and consistency of the workpiece 20 during the conveying process, and avoid the tilt or instability of the workpiece 20 that may be caused by single-point support. Since the outer peripheral surface of the first transmission shaft 121 is used to receive the first surface 21 of the workpiece 20, the contact area between the workpiece 20 and the first transmission shaft 121 is small, thereby reducing friction and reducing possible wear on the surface of the workpiece 20, which is particularly suitable for workpieces 20 with smooth or sensitive surfaces. The first gap 122 between adjacent transmission shafts allows the device to flexibly adapt to workpieces 20 of different sizes. The workpiece 20 can be carried by multiple transmission shafts at the same time and transported across multiple transmission shafts, which improves the applicability and flexibility of the device. In addition, since the transmission shafts are independently arranged, any problem with any transmission shaft can be maintained and replaced separately without affecting the normal operation of other transmission shafts, reducing maintenance costs and time.

[0038] See also Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8In some embodiments, the workpiece adjustment device 10 further includes a lifting mechanism 500, which is disposed on the first frame 110 and located on a side of the intercepting member 400 away from the second conveying assembly 220. The lifting mechanism 500 can perform lifting and lowering motion relative to the first conveying assembly 120 in the height direction. When the adsorption assembly 320 is in the first position, the lifting mechanism 500 can lift the workpiece 20 intercepted by the intercepting member 400 on the first conveying assembly 120 so that the second surface 22 of the workpiece 20 contacts the adsorption assembly 320. The lifting mechanism 500 can lift the workpiece 20 from the first conveying assembly 120 so that the second surface 22 of the workpiece 20 contacts the adsorption assembly 320 accurately. This design ensures that the adsorption assembly 320 can firmly adsorb the workpiece 20, thereby improving the accuracy and stability of the flipping operation. In addition, this also means that when installing the workpiece adjustment device 10, it is possible to prioritize ensuring that the adsorption assembly 320 in the second position can be flush with the top surface of the second conveying assembly 220, while the adsorption assembly 320 in the first position can have a large redundant installation space. In other words, the adsorption assembly 320 does not have to be too close to the first conveying assembly 120. Even if there is a certain distance between the adsorption assembly 320 in the first position and the workpiece 20 on the first conveying assembly 120, the lifting mechanism 500 can lift the workpiece 20 so that it is adsorbed by the adsorption assembly 320 in the first position. It can be understood that the lifting mechanism 500 can be adjusted according to the thickness and size of the workpiece 20 to ensure that workpieces 20 of different specifications can be accurately lifted and contacted with the adsorption assembly 320, thereby improving the applicability and flexibility of the device. In addition, when the adsorption assembly 320 is in the first position, in order to allow the adsorption assembly 320 and the first transmission shaft below to place two workpieces 20 without interfering with friction, the distance between the adsorption assembly 320 in the first position and the top surface of the first transmission shaft can be set to be greater than the thickness of the two workpieces 20. When the lifting mechanism 500 lifts up the workpiece 20 and the workpiece 20 is adsorbed by the adsorption assembly 320 in the first position, the lifting mechanism 500 can be lowered to below the first conveying axis 121. At this time, the lifting mechanism 500 will not affect the normal transportation of the workpiece 20 on the first conveying axis 121, and the workpiece 20 can be conveyed to the location of the intercepting member 400 at the end in the first direction.In other words, the adsorption component 320 in the first position can adsorb one workpiece 20, and after the lifting mechanism 500 descends, another workpiece 20 can also be transferred to the bottom of the workpiece 20 that has been adsorbed by the adsorption component 320 in the first position, because the adsorption component 320 does not necessarily turn it over and transfer it immediately after adsorbing a workpiece 20, but it also depends on the operation of other conveying lines such as the second conveying mechanism 200. At this time, even if the adsorption component 320 has adsorbed a workpiece 20 and is still in the first position, new workpieces 20 can continue to be placed below it to prepare for the next workpiece 20 lifting, adsorption and flipping operation, thereby improving production efficiency.

[0039] Specifically, Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, in some embodiments, the lifting mechanism 500 includes a bracket 510, a driving member 520 and a movable frame 530 arranged on the first frame 110, the driving member 520 is connected to the bracket 510 and is located below the first transmission shaft 121, the movable frame 530 includes a fixed portion 531 and an extension portion 532, the fixed portion 531 is connected to the driving member 520, the extension portion 532 is arranged on a side of the fixed portion 531 close to the first transmission shaft 121, the free end of the extension portion 532 is located in the first gap 122 and is used to abut the first surface 21 of the workpiece 20; the movable frame 5 The first conveying shaft 121 can be driven by the driving member 520 to move up and down relative to the first conveying shaft 121 in the height direction. When the free end of the extension portion 532 is lower than the first conveying shaft 121 in the height direction, the first conveying shaft 121 can drive the workpiece 20 to move in the first direction until the workpiece 20 is intercepted by the intercepting member 400. When the free end of the extension portion 532 is higher than the first conveying shaft 121 in the height direction, the free end of the extension portion 532 can lift the workpiece 20 on the first conveying shaft 121 so that the second surface 22 of the workpiece 20 contacts the adsorption assembly 320. It can be understood that when the adsorption assembly 320 is not in the first position, or there is no workpiece 20 above the extension portion 532, the extension portion 532 can be lowered to below the first conveying shaft 121 to prevent the extension portion 532 from conveying the workpiece 20 on the first conveying shaft 121, so that the workpiece 20 can be smoothly conveyed to the predetermined position and intercepted by the intercepting member 400. The component to be adsorbed 320 is in the first position, and the workpiece 20 on the first conveying component 120 has also arrived at the predetermined position and is intercepted by the intercepting member 400. At this time, the extension portion 532 can rise under the drive of the driving member 520 to lift the workpiece 20 so that the second surface 22 of the workpiece 20 is adsorbed by the adsorption component 320.

[0040] More specifically, if Figure 7 and Figure 8 As shown, in some embodiments, the number of the extension parts 532 is set to be multiple, and the multiple extension parts 532 are all connected to the fixing part 531. The multiple extension parts 532 are arranged in parallel and at intervals along the first direction. The free ends of the multiple extension parts 532 are respectively located in the multiple first gaps 122. The multiple extension parts 532 can be driven by the driving member 520 to synchronously move up and down in the multiple first gaps 122, and the free ends of the multiple extension parts 532 are used to abut the first surface 21 of the same workpiece 20. The arrangement of multiple extension parts 532 can provide more uniform support, so that the workpiece 20 is subjected to more uniform force during the lifting process, avoiding the tilting or instability of the workpiece 20 that may be caused by a single extension part 532, and also provides greater flexibility and adaptability, and is suitable for workpieces 20 of various specifications. Through the synchronous lifting and lowering movement of the multiple extension parts 532 driven by the driving member 520, the workpiece 20 can seamlessly switch between the conveying of the first conveying shaft 121 and the lifting of the multiple extension parts 532, so as to achieve efficient conveying and lifting operations of the workpiece 20.

[0041] More specifically, if Figure 8 As shown, in some embodiments, the free end of the extension portion 532 is provided with an adsorption portion 533, and the adsorption portion 533 is used to adsorb the first surface 21 of the workpiece 20. The adsorption portion 533 can be regarded as a part of the free end of the extension portion 532, so when judging the relative height between the free end of the extension portion 532 and the first transmission shaft, the adsorption portion 533 can be taken into consideration, that is, the relative height between the adsorption portion 533 on the end surface of the free end of the extension portion 532 and the first transmission shaft. The free end of the extension part 532 is provided with an adsorption part 533. Before the second surface 22 of the workpiece 20 is adsorbed by the adsorption component 320, the adsorption part 533 of the extension part 532 can first adsorb the first surface 21 of the workpiece 20, so that the workpiece 20 is more stable during the lifting process, and the workpiece 20 is prevented from sliding or tilting due to gravity or other factors. After the adsorption component 320 adsorbs the second surface 22 of the workpiece 20, the adsorption part 533 can release the first surface 21 of the workpiece 20, so that the adsorption component 320 of the flipping mechanism 300 can complete the subsequent flipping operation of the workpiece 20 under the drive of the rotating shaft 310. In addition, this design can adapt to workpieces 20 of different specifications and sizes. By adjusting the lifting position of the extension part 532 and the adsorption strength of the adsorption part 533, it is ensured that different workpieces 20 can be accurately lifted and adsorbed, thereby improving the applicability and flexibility of the device.

[0042] More specifically, if Figure 7 and Figure 8As shown, in some embodiments, the free end of the extension portion 532 is further provided with two limiting portions 534, the two limiting portions 534 are arranged relatively spaced apart in the axial direction of the first conveying shaft 121, the spacing between the two limiting portions 534 is greater than or equal to the width of the workpiece 20 in the axial direction of the first conveying shaft 121, and the two limiting portions 534 are used to limit the workpiece 20 in the axial direction of the first conveying shaft 121. The two limiting portions 534 limit the workpiece 20 in the axial direction of the first conveying shaft 121, ensuring that the workpiece 20 will not be offset in the process of lifting and adsorption, ensuring that the workpiece 20 is more stable in the process of lifting and adsorption, and improving the accuracy and stability of the flipping operation.

[0043] See also Figure 1 and Figure 3 In some embodiments, a notch 232 is provided at one end of the second conveying mechanism 200 close to the flipping mechanism 300, and when the adsorption component 320 is in the second position, the adsorption component 320 is located in the notch 232. A notch 232 is provided at one end of the second conveying mechanism 200 close to the flipping mechanism 300, so that the adsorption component 320 can smoothly enter the notch 232 when in the second position, that is, the notch 232 provides an escape space for the adsorption component 320 to move to the second position.

[0044] Specifically, Figure 1 As shown, in some embodiments, the second conveying assembly 220 includes a plurality of second conveying shafts, the plurality of second conveying shafts are arranged on the second frame 210 and are parallel to each other, the plurality of second conveying shafts are aligned along the second direction and are arranged at intervals, the outer peripheral surfaces of the plurality of second conveying shafts are all used to receive the second surface 22 of the workpiece 20, and the plurality of second conveying shafts can rotate to drive the workpiece 20 to move along the second direction. The outer peripheral surfaces of the plurality of second conveying shafts are all used to receive the second surface 22 of the workpiece 20, ensuring that the workpiece 20 remains stable during the conveying process and is not prone to tilting or displacement. This design can adapt to workpieces 20 of different specifications and sizes. By adjusting the spacing of the second conveying shafts and the moving range of the adsorption assembly 320, it is ensured that different workpieces 20 can be accurately conveyed, thereby improving the applicability and flexibility of the device.

[0045] More specifically, in some embodiments, the first direction is parallel to the second direction.

[0046] Specifically, Figure 1As shown, in some embodiments, the second conveying mechanism 200 further includes at least one group of driven components 230, all of which are located between the second conveying component 220 and the flipping mechanism 300, each group of driven components 230 includes two driven shafts 231, the two driven shafts 231 are rotatably connected to the two sides of the second frame 210, the two driven shafts 231 are coaxially arranged, the two driven shafts 231 are relatively spaced to form a notch 232, when the adsorption component 320 is in the second position, the adsorption component 320 is located in the notch 232, and the outer peripheral surfaces of the two driven shafts 231 are used to receive the second surface 22 of the workpiece 20. By arranging at least one group of driven components 230 in the second conveying mechanism 200, the adsorption component 320 can smoothly enter the notch 232 and place the workpiece 20 on the driven shaft 231 when in the second position. Through the rotation of the driven shaft 231, the workpiece 20 can smoothly transition to the second conveying component 220. This design not only optimizes space utilization and device layout, but also improves the efficiency and stability of turning over and conveying the workpiece 20. Through automated control and flexible adaptation to workpieces 20 of different specifications, this design significantly improves the reliability and efficiency of the overall device.

[0047] See also Figure 2 In some embodiments, the flipping mechanism 300 further includes a power member 330, and the power of the power member may include but is not limited to a motor, etc. The power member 330 is disposed on the second frame 210, and the power member 330 is connected to the rotating shaft 310 and is used to drive the rotating shaft 310 to rotate, so as to drive the adsorption assembly 320 to rotate to the first position and the second position. By driving the rotating shaft 310 to rotate by the power member 330, the adsorption assembly 320 can be rotated accurately, ensuring that the workpiece 20 can be accurately moved from the first position to the second position. Multiple adsorption assemblies 320 can be on the same rotating shaft 310 at the same time, so that multiple adsorption assemblies 320 can be synchronously driven by a power member 330 and a rotating shaft 310 to simultaneously realize the flipping and transfer of multiple workpieces 20.

[0048] Specifically, Figure 4 and Figure 5 As shown, in some embodiments, the adsorption assembly 320 can be rotated 180 degrees driven by the rotating shaft 310 to Figure 4 The first position shown is similar to Figure 5The adsorption component 320 is switched between the second position shown. The rotation direction of the adsorption component 320 when switching from the first position to the second position is opposite to the rotation direction of the adsorption component 320 when switching from the second position to the first position. By designing the adsorption component 320 to adopt opposite rotation directions when switching between different positions, path optimization and operational stability are achieved. The opposite rotation direction not only avoids mechanical interference and damage to the workpiece 20, but also improves the durability of the adsorption component 320 and the simplicity of the control system. This design significantly improves the efficiency and safety of the flipping and conveying operations of the workpiece 20.

[0049] Specifically, Figure 4 and Figure 5 As shown, in some embodiments, the adsorption assembly 320 includes a support rod 321 and an adsorption member 322, one end of the support rod 321 is connected to the outer peripheral surface of the rotating shaft 310, and the other end of the support rod 321 is connected to the adsorption member 322, and the adsorption member 322 is used to adsorb the workpiece 20. Figure 4 As shown, when the adsorption component 320 is in the first position, the support rod 321 is located above the top surface of the first conveying component 120, the support rod 321 is parallel to and spaced from the workpiece 20, and the adsorption member 322 is located below the support rod 321, and the adsorption member 322 faces and adsorbs the workpiece 20. Figure 5 As shown, when the adsorption assembly 320 is in the second position, the support rod 321 is located below the top surface of the second conveying assembly 220, the support rod 321 is parallel to and spaced from the workpiece 20, the adsorption member 322 is located above the support rod 321, the adsorption member 322 faces and releases the workpiece 20, and the adsorption member 322 is flush with the top surface of the second conveying assembly 220. It can be understood that the workpiece 20 and the adsorption assembly 320 both have a certain thickness. If the top surfaces of the first conveying assembly 120 and the second conveying assembly 220 are in the same plane, it is difficult to satisfy the adsorption assembly 320 to pick up the workpiece 20 in parallel and place the workpiece 20 in parallel. If the adsorption assembly 320 in the first position rotates to the top of the first conveying assembly 120 and is just parallel to the workpiece 20, since the workpiece 20 and the adsorption assembly 320 both have a certain thickness, the adsorption assembly 320 and the workpiece 20 in the second position cannot be parallel to the top surface of the second conveying assembly 220. The present application specifically designs the top surface of the second conveying component 220 to be higher in height than the top surface of the first conveying component 120. This height difference design facilitates the smooth flipping operation, so that the adsorption component 320 in the second position is flush with the top surface of the second conveying component 220, and the second surface 22 of the workpiece 20 is in parallel contact with the top surface of the second conveying component 220, thereby further improving the stability and accuracy of the flipping and transfer of the workpiece 20.

[0050] In addition, the present application also provides a detection device, which includes an optical detection device and a workpiece adjustment device 10 as described in any of the above embodiments, and the optical detection device is used to detect the workpiece 20.

[0051] The above detection device, because it includes the workpiece adjustment device 10 described in any of the above embodiments, also has at least the following beneficial effects:

[0052] First, efficient and accurate flipping operation: This device is particularly suitable for workpieces 20 that require high-precision inspection, such as glass cover plates. Through the flipping operation, the curved surface is facing upward, which is convenient for inspecting the curved surface and the plane of the back surface, thereby improving the accuracy and efficiency of the inspection. By moving the adsorption component 320 from the first position to the second position, efficient and accurate flipping of the workpiece 20 can be achieved. When the workpiece 20 is on the first conveying component 120, its first surface 21 faces downward; after the adsorption component 320 is flipped, when the workpiece 20 is transferred to the second conveying component 220, the second surface 22 faces downward. This design ensures the stability and accuracy of the workpiece 20 during the flipping process, and avoids the problem of offset or misalignment that may occur during the flipping process.

[0053] Second, the workpiece 20 is placed stably: in the second position after the flipping is completed, the top surface of the second conveying assembly 220 is just in contact with the second surface 22 of the workpiece 20, and the adsorption assembly 320 is located below the workpiece 20. At this time, the side of the adsorption assembly 320 close to the workpiece 20 is also just flush with the top surface of the second conveying assembly 220, so that the workpiece 20 can be accurately and stably placed on the second conveying assembly 220, ensuring the stable placement of the workpiece 20 and avoiding tilting or instability.

[0054] Third, the automatic release mechanism: after the adsorption component 320 stably places the workpiece 20 on the second conveying component 220, it will automatically release the workpiece 20 and stop adsorbing. This automatic release mechanism simplifies the operation steps, improves the efficiency of the turning and conveying process, and reduces the necessity of human intervention.

[0055] Fourth, reasonable height difference design: It can be understood that the workpiece 20 and the adsorption assembly 320 both have a certain thickness. If the top surfaces of the first conveying assembly 120 and the second conveying assembly 220 are in the same plane, it is difficult to satisfy the adsorption assembly 320 to pick up the workpiece 20 in parallel and place the workpiece 20 in parallel. If the adsorption assembly 320 in the first position rotates to the top of the first conveying assembly 120 and is just parallel to the workpiece 20, since the workpiece 20 and the adsorption assembly 320 both have a certain thickness, the adsorption assembly 320 and the workpiece 20 in the second position cannot be parallel to the top surface of the second conveying assembly 220. However, the present application specifically designs that the top surface of the second conveying assembly 220 is higher than the top surface of the first conveying assembly 120 in the height direction. This height difference design helps the smooth flipping operation, so that the adsorption assembly 320 in the second position is flush with the top surface of the second conveying assembly 220, and the second surface 22 of the workpiece 20 is just parallel to the top surface of the second conveying assembly 220. The design is realized, which further improves the stability and accuracy of the flipping and transfer of the workpiece 20.

[0056] To sum up, the workpiece adjustment device 10 provided in the present application solves the stability and precision problems existing in the prior art through reasonable structural design and height difference setting, significantly improves the efficiency and reliability of the workpiece 20 flipping and conveying process, and is particularly suitable for workpiece 20 flipping operations that require high-precision detection.
