[0040] The following is for reference. Figures 1-3 The present invention describes a flipping assembly 100 and a vision inspection mechanism 1000 according to embodiments of the present invention.

[0041] Example 1

[0042] like Figure 1 As shown, a first aspect embodiment of the present invention provides a flipping assembly 100. The flipping assembly 100 includes a flipping element 2, a support platform 1, a first linear drive device 3, and a second linear drive device 4.

[0043] like Figure 1 As shown, the flipping element 2 can be rotated in a controlled manner along the rotation axis, and the flipping element 2 can drive the product to be tested 2000 to flip when rotating.

[0044] like Figure 1 and Figure 2 As shown, the support platform 1 has a support surface 11 and a clearance groove 12. The clearance groove 12 extends through the support surface 11 and is arranged along a first direction D1 parallel to the support surface 11. The clearance groove 12 also extends through at least one end of the support platform 1 in the first direction D1 to form an opening 13. The clearance groove 12 is used to avoid the flipping element 2, and the support surface 11 is used to support the product 2000 to be tested.

[0045] like Figure 1 As shown, the first linear drive device 3 can drive the flipping element 2 to move along the first direction D1, so that the flipping element 2 can exit the clearance groove 12 from the opening 13.

[0046] like Figure 1 As shown, the second linear drive device 4 is used to drive the flipping element 2 to move along the height direction D3 perpendicular to the support surface 11 to enter the clearance groove 12.

[0047] The support surface 11 here is specifically constructed as the upper surface of the support platform 1, which can lift the product 2000 to be tested from the lower side.

[0048] It should be further explained that the flipping element 2 here can be specifically constructed as a flipping rod 21, a flipping block, a flipping arm, a clamp, or other irregular structural parts, and its specific shape is not limited here.

[0049] In a specific application scenario, after the adsorption element 22 of the flipping element 2 adsorbs the A side of the product to be tested 2000, the second driving device drives the flipping element 2 to move in the height direction D3 to suspend the product above the support surface 11. Then, the flipping element 2 drives the adsorption element 22 to flip to flip the product to be tested 2000 from the A side to the B side. After flipping, the A side of the product to be tested 2000 is opposite to the support surface 11, and the B side of the product to be tested is opposite to the support surface 11. After the flipping element 2 approaches the support surface 11, it enters the clearance groove 12. The support surface 11 supports the product to be tested 2000 and contacts the A side of the product to be tested 2000, and the B side of the product to be tested 2000 faces upward. After the adsorption element 22 of the flipping element 2 stops adsorbing the A side of the product to be tested 2000, the first linear drive device 3 drives the flipping element 2 to exit the clearance groove 12 from the opening 13 of the clearance groove 12 along the first direction D1. The product to be tested 2000 is placed on the support surface 11 of the support platform 1 with the B side facing up, thereby realizing the flipping of the product to be tested 2000.

[0050] As can be seen from the technical solution, the embodiments provided by this utility model have the following advantages:

[0051] (1) The flipping component 100 can replace manual flipping operations, reducing repetitive labor for workers;

[0052] (2) When applied in the field of product appearance inspection, the flipping component 100 can automatically complete the posture switching of the product to be inspected 2000 without manual intervention, adapting to the pace of high-speed production lines and improving inspection efficiency.

[0053] (3) By setting the clearance groove 12 to pass through one side of the first direction D1 to form an opening 13 in coordination with the first linear drive device 3, the flipping element 2 can be completely removed from the detection area without blocking the subsequent process, thus reducing the mechanical interference between the support platform 1 and the flipping element 2.

[0054] (4) The second linear drive device 4 can control the contact force between the product and the support surface 11, reducing impact.

[0055] Example 2

[0056] like Figure 2 As shown, further, the width direction of the clearance groove 12 is a second direction D2 parallel to the support surface 11, and the second direction D2 is perpendicular to the first direction D1. The groove width is greater than the maximum rotation diameter of the flipping element 2 and less than the width of the product to be tested 2000 in the second direction D2, so that the product to be tested 2000 can cross the clearance groove 12 and be supported by the support surfaces 11 on both sides. That is, the product to be tested 2000 rests on the clearance groove 12 through the support surfaces 11 on both sides in the second direction D2.

[0057] like Figure 2 As shown, both the first direction D1 and the second direction D2 are parallel to the support surface 11. For example, one of the first direction D1 and the second direction D2 is the X direction parallel to the support surface 11, and the other is the Y direction parallel to the support surface 11.

[0058] The maximum rotation diameter here is twice the maximum rotation radius, which refers to the vertical distance from the axis to the axis at the point on the outer periphery of the flipping element 2 when it rotates along the rotation axis. Therefore, the flipping element 2 can rotate freely within the clearance groove 12 without contacting the groove wall, avoiding mechanical interference or wear.

[0059] It should be further noted that the flipping element 2 here can be specifically constructed as a flipping rod 21, a flipping block, a flipping arm, a clamp, or other irregularly shaped structural parts; its specific shape is not limited here. For non-centrally symmetrical irregularly shaped structural parts, the maximum rotation diameter of the flipping element 2 is the maximum value of the diameter of the rotation envelope circle.

[0060] (1) By setting the width of the clearance groove 12 to be greater than the maximum rotation diameter of the flipping element 2, it is beneficial to further reduce the interference between the flipping element 2 and the clearance groove 12. In particular, the flipping element 2 can fall vertically into the clearance groove 12 at any rotation angle, and can also exit the opening 13 along the first direction D1 at any rotation angle. There is no need to deliberately control the rotation angle of the flipping element 2, which reduces the complexity of the control scheme of the flipping element 2 and simplifies the control scheme.

[0061] (2) By setting the width of the clearance groove 12 to be less than the width of the product to be tested 2000 in the second direction D2, the product to be tested 2000 is supported on the clearance groove 12 by the two side support surfaces 11 on the second direction D2 through the clearance groove 12, which improves the stability of the support surface 11.

[0062] like Figure 2 As shown, the depth direction of the clearance groove 12 is perpendicular to the height direction D3 of the support surface 11, and the groove depth is configured to be greater than the maximum rotation diameter of the flipping element 2. This design allows the second linear drive device 4 to control the flipping element 2 to drive the product to adhere to the support surface 11 and then the adsorption element 22 stops adsorbing the product, thereby reducing the instantaneous impact of the product 2000 under test due to free fall and reducing the possibility of damage to the product due to vertical impact with the support surface 11.

[0063] It should be noted that the timing control method, such as controlling the flipping element 2 to drive the product to adhere to the support surface 11 through the second linear drive device 4, and then the adsorption element 22 stopping adsorbing the product, is a method that can be implemented by those skilled in the art based on common knowledge. These methods are not within the scope of this solution. The above description is only to illustrate the beneficial effects that can be achieved by this hardware structure improvement in combination with common knowledge. The effect of this new embodiment does not depend on the implementation of these methods used for illustration.

[0064] like Figure 2 As shown, further, there are multiple clearance slots 12, which are arranged in parallel at intervals along the second direction D2. Each clearance slot 12 can correspond to an independent flipping station, and multiple clearance slots 12 can process multiple products simultaneously.

[0065] Example 2

[0066] like Figure 1 As shown, in some embodiments, the first linear drive device 3 includes a first linear drive motor 31 and a first mounting bracket 32. The first mounting bracket 32 ​​has bearing holes for rotatably mounting the flipping element 2. The first mounting bracket 32 ​​is connected to the drive end of the first linear drive motor 31 to drive the flipping element 2 to move in the first direction D1. The second linear drive device 4 includes a second linear drive motor 41 and a second mounting bracket 42. The first linear drive device 3 is mounted on the second mounting bracket 42. The second mounting bracket 42 is connected to the drive end of the second linear drive motor 41 to drive the first drive device to move in the height direction D3 perpendicular to the support surface 11. The first mounting bracket 32 ​​serves as a rotation support platform 1 for the flipping element 2, forming a rigid connection with the flipping element 2 through the bearing holes to ensure the stability of the rotation axis. The second mounting bracket 42 provides a stable mounting foundation for the first linear drive device 3, reducing vibration during movement.

[0067] Example 3

[0068] like Figure 1 As shown, the flipping element 2 further includes a plurality of flipping rods 21, and the adsorption member 22 is disposed on the flipping rods 21 to adsorb the product 2000 to be tested. The flipping assembly 100 also includes a rotation drive assembly 6, which is used to drive the plurality of flipping rods 21 to rotate synchronously.

[0069] As can be seen from the above embodiments, multiple flipping rods 21 and multiple clearance slots 12 are arranged in a one-to-one correspondence. That is, multiple flipping rods 21 are arranged sequentially along the second direction D2, and the interval between two adjacent flipping rods 21 is the same as the interval between two adjacent clearance slots 12. Multiple products can be flipped at the same time, which further improves the flipping efficiency and thus improves the detection efficiency.

[0070] In some specific examples, the flipping rod 21 is constructed as a rotating body coaxial with the rotation axis, and the flipping rod 21 extends along the direction of the rotation axis. The outer peripheral surface of the flipping rod 21 is rotatably connected in a bearing hole. One end of the flipping rod 21 is provided with an adsorption element 22, which is a vacuum adsorption device that can adsorb the surface of the product 2000 to be tested when a negative pressure is formed.

[0071] like Figure 1 As shown, the rotary drive assembly 6 includes a rotary drive motor 61, a drive wheel 62, a first transmission belt (not shown), multiple second transmission belts (not shown), and multiple driven wheels 63. The drive wheel 62 is connected to one of the driven wheels 63 via the first transmission belt and is driven by the rotary drive motor 61 to rotate the driven wheel 63. Adjacent driven wheels 63 are connected by the second transmission belt to rotate synchronously. The driven wheels 63 and the tilting rod 21 are coaxially fixed. Specifically, the tilting rod 21 has two driven wheels 63. One driven wheel 63 is connected to another driven wheel 63 on the adjacent upper tilting rod 21 via the second transmission belt, and the other driven wheel 63 is connected to a driven wheel 63 on the adjacent lower tilting rod 21 via the second transmission belt. One driven wheel 63 on one tilting rod 21 is connected to the drive wheel 62 via the first transmission belt, and the other driven wheel 63 on one tilting rod 21 is connected to a driven wheel 63 on the adjacent tilting rod 21 via the second transmission belt.

[0072] Example 4

[0073] like Figure 3 As shown, a second aspect embodiment of the present invention provides a visual inspection mechanism 1000, which includes a base 200, a movable seat 300, a detection component 400, and a flipping component 100 of the first embodiment of the present invention. The movable seat 300 is movably disposed on the base 200 along a second direction D2, and the movable seat 300 can hold a product 2000 to be inspected; the flipping component 100 is disposed on one side of the movable seat 300 in a first direction D1, so that the flipping component 100 can transfer the product 2000 to be inspected onto the movable seat 300; the detection component 400 is used to perform appearance inspection on the product 2000 to be inspected on the movable seat 300.

[0074] like Figure 3As shown, in a specific application scenario, after the detection component 400 completes the detection of side A of the product 2000 to be detected on the movable base 300, the movable base 300 moves the product 2000 to be detected until it is aligned with the position of the flipping component 100. The flipping component 100 drives the flipping element 2 to approach the movable base 300 along the first direction D1 via the first linear drive mechanism, and then moves downwards to approach the movable base 300 via the second linear drive mechanism to adsorb side A of the product 2000 to be detected; the second drive device drives the flipping element 2 The product 2000 is moved in the height direction D3 to suspend it above the support surface 11 and the moving seat 300. Then, the flipping element 2 drives the adsorption member 22 to flip, thus flipping the product 2000 to be tested from side A to side B. After flipping, side A of the product 2000 to be tested faces the support surface 11, and side B of the product 2000 to be tested faces away from the support surface 11. After the flipping element 2 approaches the support surface 11, it enters the clearance groove 12. The support surface 11 holds the product 2000 to be tested and contacts side A of the product 2000 to be tested, with side B of the product 2000 facing upwards. After the adsorption member 22 of the flipping element 2 stops adsorbing side A of the product 2000 to be tested, the first linear drive device 3 drives the flipping element 2 to exit the clearance groove 12 from the opening 13 of the clearance groove 12 along the first direction D1. The product 2000 to be tested is placed on the support surface 11 of the support platform 1 with side B facing upwards, thereby realizing the flipping of the product 2000 to be tested. The first linear drive device 3 and the second linear drive device 4 work together to adsorb the B side of the product to be tested 2000, placing the product to be tested 2000 with its B side facing up on the movable seat 300. The movable seat 300 then moves the product to be tested 2000 to the testing component 400 for appearance inspection.

[0075] In the above process, before and after flipping the product 2000 to be inspected, the flipping component 100 can also act as a transfer station, directly transferring the product between the support platform 1 and the movable seat 300, reducing the additional handling mechanisms in traditional production lines and improving the structural compactness of the vision inspection mechanism 1000. It should be noted that the above-described timing control method is a method that can be implemented by those skilled in the art based on common knowledge. These methods are not within the scope of this solution. The above description is merely to illustrate the beneficial effects that this hardware structure improvement can achieve, based on common knowledge. The effects achieved in this novel embodiment do not depend on the implementation of these illustrative methods.

[0076] Example 5

[0077] like Figure 3As shown, the movable seat 300 further includes a first movable seat 310 and a second movable seat 320, which are spaced apart along a second direction D2. The first movable seat 310 can move along the second direction D2, and the second movable seat 320 can also move along the second direction D2. The detection component 400 includes a first detection component 410 and a second detection component 420 spaced apart along the second direction D2. The first detection component 410 can detect the product 2000 to be detected on the first movable seat 310, and the second detection component 420 is used to detect the product 2000 to be detected on the second movable seat 320. The flipping component 100 also includes a third linear drive device 5, which is used to drive the flipping component 100 to move in the second direction D2 to transfer the product 2000 to be detected between the first movable seat 310 and the second movable seat 320.

[0078] This means that the first detection component 410 and the second detection component 420 independently and simultaneously detect the product 2000 to be inspected on the first moving seat 310 and the second moving seat 320, respectively, thereby further improving the detection efficiency. The flipping component 100 can transfer the product 2000 to be inspected between the two moving seats 300 through the third linear drive device 5, thereby further improving the structural compactness of the vision inspection mechanism 1000.

[0079] In a specific example, the visual inspection mechanism 1000 also includes a feeding mechanism for conveying the product 2000 to be inspected to the first movable seat 310. The first movable seat 310 moves the product 2000 to be inspected to the first inspection component 410, which inspects side A of the product 2000 on the first movable seat 310. After the inspection is completed, the first movable seat 310 moves the product 2000 to the corresponding position of the flipping component 100, which flips the product 2000 so that side B is facing up. The first movable seat 310 moves the product 2000 to be inspected with its B side facing up to the first inspection component 410. The first inspection component 410 inspects the B side of the product 2000 on the first movable seat 310. After inspection, the first movable seat 310 moves the product 2000 to the corresponding position of the flipping component 100. The flipping component 100 moves the product 2000 from the first movable seat 310 to the second movable seat 320. At this time, the first movable seat 310 obtains the next batch of products 2000 to be inspected from the feeding mechanism. The first inspection component 410 and the second inspection component 420 perform inspection work simultaneously.

[0080] It should also be noted that after the second inspection agency completes the inspection of the product 2000 to be inspected on the second moving seat 320, the second moving seat 320 moves the product 2000 to the discharge mechanism for transfer to the next process.

[0081] It should also be noted that the movable seat 300 is driven by the movable seat linear drive device 500. Specifically, the movable seat linear drive device 500 includes a first movable seat drive device 510 and a second movable seat drive device 520. The first movable seat drive device 510 drives the first movable seat 310 to move along the second direction, and the second movable drive device 520 drives the second movable seat 320 to move along the second direction.

[0082] In conjunction with the above embodiments, the third linear drive device 5 includes a third linear drive motor 51 and a third mounting bracket 52. The drive end of the third linear drive motor 51 is connected to the third mounting bracket 52 to drive the third mounting bracket 52 to move along the second direction D2. The third linear drive device 5 is directly mounted on the second mounting bracket 42, and the first linear drive device 3 is directly mounted on the third mounting bracket 52.

[0083] like Figure 3 As shown, in some embodiments, the first detection component 410 includes a visual inspection camera 81 and a visual inspection light source 82 and is used to detect the chamfer and bevel of the product 2000 to be inspected; the second detection component 420 includes a pair of appearance inspection cameras 91 and is used to detect the thickness and length of the product 2000 to be inspected. The pair of appearance inspection cameras 91 are respectively arranged on both sides of the second movable seat 320 in the height direction D3. At least a portion of the second movable seat 320 is a transparent structure for placing the product 2000 to be inspected.

[0084] like Figure 3 As shown, in some embodiments, the first detection component 410 further includes a camera driving device 83 and a light source driving device 84, respectively used to drive the visual inspection camera 81 and the visual inspection light source 82 to move; the second detection component 420 further includes a second detection component driving device 93, which drives a pair of appearance inspection cameras 91 to move towards or away from each other. When inspecting the four sharp corners of the product 2000 to be inspected, the light source needs to illuminate the product to provide brightness for the camera to take pictures. The synchronous movement of the visual inspection camera 81 and the visual inspection light source 82 helps to improve the stability of the light source, thereby improving the accuracy of the inspection. The second detection component 420 also includes a second detection component driving device 93, which drives a pair of appearance inspection cameras 91 to move towards or away from each other to adjust the distance between them and the product 2000 to be inspected on the second moving base 320, facilitating focusing.

[0085] like Figure 3 As shown, the second detection component 420 also includes a thickness measuring mechanism 92 fixed above the second movable seat 320, which is used to measure the thickness of the product on the second movable seat 320.

[0086] In some specific examples, the first movable seat 310 may also be equipped with a vacuum adsorption device to adsorb the product 2000 to be tested.

[0087] like Figure 3 As shown, in some specific examples, the first linear drive device 3, the second linear drive device 4, the third linear drive device 5, the moving seat drive device 500, the camera drive device 83, the light source drive device 84, and the second detection component drive device 93 are all equipped with lead screw transmission components for guidance. (1) The lead screw has high running accuracy and precise motion positioning, ensuring that the vision camera is perpendicular to the product detection surface, thereby improving the product detection accuracy. (2) By combining multiple lead screws, the detection accuracy and detection efficiency are improved, which helps to improve the accuracy of detection.

[0088] It should also be emphasized that the product to be tested 2000 here can be a germanium square sheet. In the relevant technology, after the product to be tested 2000 is transferred to the testing station, the inspectors first inspect the product size, using a micrometer to measure the length, width and thickness of the product. After the size inspection is completed, the chamfering and edge inspection is carried out. The chamfering and edge dimensions of the square sheet are visually measured using a chamfering mirror. After the above inspection is completed, the appearance of the square sheet is visually inspected one by one to see if there is any chipping. The product inspection has the following problems: (1) The use of measuring tools requires high skill from the operators; (2) There is a risk of misjudgment in the manual inspection of the chamfering and edge of the square sheet; (3) There is a risk of missed inspection in the manual inspection of the appearance; (4) The product is easily damaged and chipped when the length, width and thickness are manually inspected; (5) The inspection efficiency is low.

[0089] The aforementioned visual inspection unit 1000 enables automated inspection of germanium wafers, reducing inspection errors caused by human factors. Through the collaboration between various devices, damage to products is reduced and inspection efficiency is improved.
