Description

Technical Field

[0002] In the manufacturing process of IC (integrated circuit) substrates, it is necessary to accurately and quickly detect and identify scratches, dents, and other defects on the surface of the substrate, and promptly screen out defective products. To meet the needs of automated testing, the substrates usually need to be neatly arranged to facilitate the handling and testing by the testing equipment.

[0003] In related technologies, manual operation is used to stack the carrier plates into the silo. During the stacking process, adjacent carrier plates need to be stacked neatly, which has low work efficiency. Furthermore, when the testing equipment is subjected to external force or vibration, the placement of the carrier plates may be deviated, affecting subsequent handling and testing.

[0006] According to the hopper assembly of this utility model embodiment, when the locking structure is in the unlocked state, the first limiting structure moves along the first horizontal direction toward the first preset cavity wall, thereby pushing one side wall of the workpiece to abut against the first preset cavity wall.

[0038] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0039] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0040] Hereinafter, with reference to the accompanying drawings, a hopper assembly 100 according to a first aspect embodiment of the present invention will be described. It will be understood that when the hopper assembly 100 is used in the testing equipment 200, the hopper assembly 100 can be used as a loading hopper or a unloading hopper. The workpiece in the loading hopper is transferred to the unloading hopper after the image acquisition component acquires an image.

[0041] like Figures 1-6 As shown, the hopper assembly 100 includes: a hopper body 1, a support structure 2, a first limiting structure 3, and a locking structure 4. The hopper body 1 has a placement cavity 10. The support structure 2 is located in the hopper body 1 and includes a support platform 20 located in the placement cavity 10. The support platform 20 is used to place a workpiece 78, for example, the support platform 20 can be used to place an IC carrier board. One side wall of the placement cavity 10 in the first horizontal direction is a first preset cavity wall 11. The first limiting structure 3 is located in the hopper body 1 and can move relative to the support platform 20 in the first horizontal direction to push the workpiece 78 toward the first preset cavity wall 11. The first limiting structure 3 includes a plurality of first limiting rods 30 spaced apart in the second horizontal direction. The first limiting rods 30 pass through the support platform 20 in the vertical direction. The locking structure 4 has a locked state and an unlocked state. In the locked state, the locking structure 4 locks the position of the first limiting structure 3 in the first horizontal direction. In the unlocked state, the locking structure 4 releases the lock on the first limiting structure 3. The second horizontal direction intersects with the first horizontal direction, and both the first and second horizontal directions are perpendicular to the vertical direction.

[0042] As can be seen, one side wall of the placement cavity 10 in the first horizontal direction is the first preset cavity wall 11. When the locking structure 4 is in the unlocked state, the first limiting structure 3 can move relative to the support platform 20 in the first horizontal direction to push the workpiece 78 towards the first preset cavity wall 11. That is, the first limiting structure 3 can push the workpiece 78 to move relative to the support platform 20 in the first horizontal direction. For example, the first limiting structure 3 can push the workpiece 78 to abut against the first preset cavity wall 11, so that the workpiece 78 can be neatly arranged in the first horizontal direction. Then, the locking structure 4 is switched from the unlocked state to the locked state so that the first limiting structure 3 can no longer move in the first horizontal direction. For example, the first limiting structure 3 cannot move towards the first preset cavity wall 11 in the first horizontal direction. Assuming the cavity wall 11 moves, and the first limiting structure 3 cannot move away from the first preset cavity wall 11 in the first horizontal direction, the two side walls of the workpiece 78 in the first horizontal direction respectively abut against the first limiting structure 3 and the first preset cavity wall 11, so that the workpiece 78 is sandwiched between the first limiting structure 3 and the first preset cavity wall 11, so that the workpiece 78 is not easy to move relative to the support platform 20 in the first horizontal direction and change the relative position of the workpiece 78 and the first preset cavity wall 11. The placement position of the workpiece 78 in the first horizontal direction can be more stable, and when there are multiple workpieces 78 stacked in the vertical direction, the placement position of multiple workpieces 78 in the first direction has good consistency, which facilitates the subsequent handling of the workpiece 78.

[0043] It is understandable that when multiple workpieces 78 stacked vertically are placed on the support platform 20, the multiple workpieces 78 can be clamped between the first limiting structure 3 and the first preset cavity wall 11 by moving the first limiting structure 3, so that the stacking of the multiple workpieces 78 can be more neat. Then, the locking structure 4 is switched from the unlocked state to the locked state. At this time, the position of the first limiting structure 3 in the first horizontal direction is locked, so that the multiple workpieces 78 can maintain a stable stacking state, which is convenient for the subsequent picking and placing of the workpieces 78.

[0044] In related technologies, manual operation is used to arrange adjacent workpieces neatly in the stacking process of multiple workpieces, which has low work efficiency. However, this application uses the first limiting structure 3 to push the workpiece 78 to move, which can realize the neat arrangement of multiple workpieces 78 stacked in the vertical direction, improve the convenience of operation, and help improve work efficiency. Moreover, by locking the first limiting structure 3 in the locked state, the placement position of the workpiece 78 can be locked, which can make the placement position of the workpiece 78 more stable and less likely to be displaced by other factors such as equipment vibration or other manual operations on the hopper assembly 100.

[0045] It is understood that if the hopper assembly 100 is used as a loading hopper, the above-mentioned configuration of this application facilitates that multiple workpieces 78 in the hopper assembly 100 have a consistent removal position in the first horizontal direction, or in other words, the removal positions of multiple workpieces 78 that are inspected sequentially have good consistency in the first horizontal direction, which facilitates the subsequent handling and inspection of workpieces 78 and ensures that workpieces 78 can achieve good matching with the image acquisition component when they are transferred to the image acquisition position of the inspection device 200. If the hopper assembly 100 is used as a unloading hopper, the above-mentioned configuration of this application facilitates that multiple workpieces 78 that have completed image acquisition are neatly stacked on the support platform 20, which facilitates their subsequent unified removal.

[0046] For example, multiple workpieces 78 are placed on the support platform 20 and between the first limiting structure 3 and the first preset cavity wall 11. When the first limiting structure 3 moves towards the first preset cavity wall 11 in the first horizontal direction, the first limiting structure 3 can push the multiple workpieces 78 towards the first preset cavity wall 11 so that one side wall of the multiple workpieces 78 can be abutted against the first preset cavity wall 11, so that the stacking of the multiple workpieces 78 can be neat. Then, the locking structure 4 is switched from the unlocked state to the locked state. At this time, the first limiting structure 3 is locked, and the multiple workpieces 78 are clamped between the first limiting structure 3 and the first preset cavity wall 11 so that the multiple workpieces 78 can maintain a stable stacking state. Even if the hopper assembly 100 is subjected to impact or external force, the multiple workpieces 78 can still maintain a stable and neat stacking state, and the workpieces 78 are not prone to slippage, which helps to improve the reliability of the hopper assembly 100.

[0047] Furthermore, the first limiting structure 3 includes a plurality of first limiting rods 30 spaced apart along the second horizontal direction. For example, the plurality of first limiting rods 30 are distributed in a dispersed manner so that the first limiting structure 3 can push workpieces 78 of different sizes. In other words, even if the size of the workpiece 78 in the second horizontal direction is small, at least some of the first limiting rods 30 can still push the workpiece 78 to move along the first horizontal direction, which facilitates the improvement of the applicability of the hopper assembly 100. The first limiting rods 30 are inserted into the support platform 20 in the vertical direction, and a portion of the first limiting rods 30 extends to the upper side of the support platform 20 so that the first limiting rods 30 extend onto the support platform 20. The side portion can reliably push all workpieces 78 placed on the support platform 20. It is understood that, to avoid the movement of the first limiting rod 30, the support platform 20 has at least one elongated opening 21 extending along the first horizontal direction. The first limiting rod 30 passes through the corresponding opening 21, allowing the first limiting rod 30 to move along the first horizontal direction within the opening 21. The support platform 20 is less likely to interfere with the movement of the first limiting rod 30, thus improving the reliability of the hopper assembly 100. The dispersed arrangement of multiple first limiting rods 30 helps to appropriately reduce the total opening area of ​​the openings 21, thereby reducing the weakening of the support platform 20. The number of openings 21 is not specifically limited; for example, the openings 21 can be arranged one-to-one with the first limiting rods 30 (e.g., ...). Figure 2 (as shown), or, one opening 21 can correspond to at least two first limiting rods 30.

[0048] like Figures 1-3 As shown, in some embodiments, the first limiting structure 3 further includes a first mounting base 31, which is connected to each first limiting rod 30. The first mounting base 31 and the bottom wall 12 of the placement cavity 10 are slidably engaged through the first guide rail structure 32. The locking structure 4 includes a locking rod 40 disposed in the placement cavity 10. The locking rod 40 passes through the first mounting base 31 in the up-down direction and is threadedly engaged with the first mounting base 31. In the locked state, the bottom end of the locking rod 40 abuts against the bottom wall 12 of the cavity. In the unlocked state, the locking rod 40 is separated from the bottom wall 12 of the cavity.

[0049] As can be seen, the first mounting base 31 is connected to each of the first limiting rods 30 (e.g., by welding, threaded connection, snap-fit, etc.) so that the multiple first limiting rods 30 can move along the first horizontal direction with the first mounting base 31. By providing a first guide rail structure 32 between the first mounting base 31 and the bottom wall 12 of the placement cavity 10, the first mounting base 31 and the multiple first limiting rods 30 can move along the first guide rail structure 32 in the first horizontal direction, so that the movement path of the first limiting structure 3 is clearer and the movement is more stable.

[0050] The locking rod 40 is threadedly engaged with the first mounting base 31 so that the locking rod 40, the first mounting base 31 and the multiple first limit rods 30 can move together in the first horizontal direction. At the same time, by rotating the locking rod 40, the setting position of the locking rod 40 in the vertical direction can be adjusted so that the locking structure 4 has a switchable locked state and unlocked state.

[0051] When the locking structure 4 is in the locked state, the bottom wall of the locking rod 40 abuts against the bottom wall 12 of the cavity, so that the locking rod 40 and the bottom wall 12 of the cavity cannot move relative to each other. Thus, the first mounting base 31 and the multiple first limiting rods 30 also cannot move relative to the bottom wall 12 of the cavity, indirectly locking the movement of the first limiting structure 3. When the locking structure 4 is in the unlocked state, the locking rod 40 is separated from the bottom wall 12 of the cavity. That is, in the vertical direction, there is a certain gap between the locking rod 40 and the bottom wall 12 of the cavity, or there is no gap and the two are not tightly abutted. At this time, the locking rod 40 can move relative to the bottom wall 12 of the cavity, thereby unlocking the first limiting structure 3 and facilitating the neat placement of the workpiece 78.

[0052] Therefore, by rotating the locking lever 40, the locking structure 4 can be switched between locked and unlocked states. The adjustment process of the locking structure 4 is relatively simple, which facilitates the improvement of the material feeding and unloading efficiency of the hopper assembly 100.

[0053] like Figures 1-6 As shown, in some embodiments, the locking lever 40 is configured to satisfy at least one of the following conditions A1 to A4:

[0054] In condition A1, in the second horizontal direction, the length of the placement cavity 10 (e.g.) Figure 4 The length of L2 is greater than the length of the support platform 20 (e.g., L2) Figure 4 L1), so that the placement cavity 10 forms an empty space 14 on one side of the support platform 20 in the second horizontal direction, and the locking rod 40 is provided in the empty space 14 and the locking rod 40 is spaced apart from the support platform 20.

[0055] As can be seen, by placing the locking lever 40 within the empty space 14 and maintaining a certain distance between the locking lever 40 and the support platform 20, a larger operating space is provided for the workers. Workers can more easily access and adjust the locking lever 40, making it less likely to interfere with the support platform 20 during adjustment, thus improving work efficiency. There is no need to machine a clearance structure on the support platform 20 to avoid the locking lever 40, which simplifies the structure of the support platform 20 and reduces its weakening. It also makes it less likely to accidentally touch the workpiece 78, preventing accidental damage. Furthermore, the empty space 14 provides a larger operating space for placing and removing the workpiece 78. For example, the length of the workpiece 78 will not exceed the length of the support platform 20. The empty space 14 provides a larger operating space for placing and removing the workpiece 78, allowing workers to smoothly handle it and reducing the possibility of damage.

[0056] In condition A2, the locking lever 40 and one of the first limiting levers 30 are integrated into one unit. By integrating the locking lever 40 and the first limiting lever 30, the installation steps can be reduced, the complexity of manual or automated assembly can be lowered, and the assembly efficiency of the hopper assembly 100 can be improved. Of course, the locking lever 40 and the first limiting lever 30 can also be set separately.

[0057] In condition A3, the top of the locking lever 40 is provided with a hand-adjusting cap 41. The outer diameter of the hand-adjusting cap 41 is larger than that of the locking lever 40. The larger size of the hand-adjusting cap 41 makes it easier for the operator to grip the hand-adjusting cap 41, allowing the operator to rotate the locking lever 40 more easily. This improves the efficiency of switching between the locked and unlocked states of the locking structure 4. At the same time, the hand-adjusting cap 41 makes it easier for the operator to distinguish between the locking lever 40 and the first limit lever 30. For example, the hand-adjusting cap 41 is a knurled nut. The knurled surface is formed with a textured surface through embossing or hobbing, which significantly increases friction and makes it easy to rotate by hand without the need for tools, thus improving work efficiency.

[0058] In condition A4, the top of the locking lever 40 extends upward beyond the first preset cavity wall 11, that is, a part of the locking lever 40 extends beyond the first preset cavity wall 11, so that the operator can more easily access and adjust the locking lever 40 without having to put their hand too far into the placement cavity 10, thereby reducing the possibility of the operator's hand touching other parts during adjustment and improving the ease of operation.

[0059] like Figures 1-6 As shown, in some embodiments, in the second horizontal direction, the length of the placement cavity 10 (e.g.) Figure 4 The length of L2 is greater than the length of the support platform 20 (e.g., L2) Figure 4The placement cavity 10 forms an empty space 14 on one side of the support platform 20 in the second horizontal direction (L1), which is understood to be part of the placement cavity 10 and located on one side of the support platform 20 in the second horizontal direction. The cavity wall of the placement cavity 10 away from the empty space 14 in the second horizontal direction is a second preset cavity wall 13, and the support platform 20 has a clearance space 15 formed at one end away from the second preset cavity wall 13 in the second horizontal direction. The hopper assembly 100 also includes a second limiting structure 5, which is disposed on the first preset cavity wall 11. The second limiting structure 5 can move relative to the support platform 20 between the empty space 14 and the clearance space 15 in the second horizontal direction to push the workpiece 78 toward the second preset cavity wall 13. The first horizontal direction is the width direction of the support platform 20, and the second horizontal direction is the length direction of the support platform 20.

[0060] As can be seen, the second limiting structure 5 has a first limit position and a second limit position. In the first limit position, at least a portion of the second limiting structure 5 is located in the empty space 14 so that there is a certain distance between the second limiting structure 5 and the support platform 20, making it less likely to interfere with the material feeding and picking of the support platform 20. In the second limit position, at least a portion of the second limiting structure 5 is located in the clearance space 15 so that the second limiting structure 5 can push the workpiece 78 toward the second preset cavity wall 13 along the second horizontal direction, so that one side wall of the workpiece 78 can abut against the second preset cavity wall 13, so that the workpiece 78 is placed more neatly and the picking and picking efficiency of the workpiece 78 is improved.

[0061] Furthermore, a clearance space 15 is formed at the end of the support platform 20 away from the second preset cavity wall 13 in the second horizontal direction. For example, in the first horizontal direction, at least a portion of the support platform 20 is spaced apart from the first preset cavity wall 11, and the aforementioned portion is arranged adjacent to the second limiting structure 5 in the second horizontal direction to form a clearance space 15 to allow the movement of the second limiting structure 5. When the second limiting structure 5 moves along the second horizontal direction, the clearance space 15 allows the second limiting structure 5 to move relative to the support platform 20, and the support platform 20 is less likely to interfere with the movement of the second limiting structure 5, which helps to improve the reliability of the hopper assembly 100.

[0062] Exemplarily, the support platform 20 includes a first part and a second part. In the second horizontal direction, the first part is disposed closer to the second limiting structure 5 than the second part. In the first horizontal direction, the first part is spaced apart from the first preset cavity wall 11, and the second part is abutted against the first preset cavity wall 11, so that a clearance space 15 is formed between the first part and the first preset cavity wall 11. This makes it less likely for the second limiting structure 5 to be disturbed by the support platform 20 when it moves along the second horizontal direction toward the second preset cavity wall 13, thereby improving the reliability of the hopper assembly 100. Furthermore, in the second horizontal direction, the length of the first part accounts for 2 / 3 of the length of the support platform 20, and the length of the second part accounts for 1 / 3 of the length of the support platform 20, that is, the length of the first part is greater than the length of the second part, so that the clearance space 15 has sufficient length, allowing the second limiting structure 5 to have a larger range of movement, making it easier to adapt to workpieces 78 of different sizes and improving the applicability of the hopper assembly 100.

[0063] For example, the first horizontal direction is the width direction of the support platform 20, the second horizontal direction is the length direction of the support platform 20, the side wall of the placement cavity 10 away from the empty space 14 in the length direction of the support platform 20 is the second preset cavity wall 13, the second limiting structure 5 can move along the length direction of the support platform 20, and the end of the support platform 20 away from the second preset cavity wall 13 in the second horizontal direction has a clearance space 15 to avoid the second limiting structure 5. The second limiting structure 5 can move along the length direction of the support platform 20 in the clearance space 15 to push the workpiece 78 toward the second preset cavity wall 13, so that the workpiece 78 is placed more neatly, which is convenient for subsequent material picking and unloading.

[0064] like Figures 1-6 As shown, in some embodiments, the second limiting structure 5 includes a second limiting rod 50 and two second mounting seats 51. The two second mounting seats 51 are respectively disposed at the upper and lower ends of the second limiting rod 50, and the second mounting seats 51 respectively cooperate with both sides of the thickness of the first preset cavity wall 11. One of the second mounting seats 51 cooperates with the side of the first preset cavity wall 11 facing the placement cavity 10, and the other second mounting seat 51 cooperates with the side of the first preset cavity wall 11 away from the placement cavity 10. Each second mounting seat 51 slides against the first preset cavity wall 11 through the second guide rail structure 52. When the two mounting bases 51 are moved together, the second limiting rod 50 can move along the second horizontal direction together with the two second mounting bases 51. By providing a second guide rail structure 52 on the second mounting base 51 and the first preset cavity wall 11, the second limiting rod 50 and the two second mounting bases 51 can move along the second guide rail structure 52 in the second horizontal direction, so that the movement path of the second limiting structure 5 is clearer, which facilitates precise control of the movement of the second limiting structure 5, and makes it possible to push the workpiece 78 to stop against the second preset cavity wall 13 more accurately, which helps to improve the reliability of the hopper assembly 100.

[0065] The second mounting base 51 is respectively fitted to both ends of the thickness of the first preset cavity wall 11, so the second limiting structure 5 can span across both ends of the thickness of the first preset cavity wall 11, which helps to improve the reliability of the fit between the second limiting structure 5 and the first preset cavity wall 11. Moreover, one of the second mounting bases 51 can be located outside the placement cavity 10, so that the operator can more conveniently control the movement of the second limiting structure 5 along the second horizontal direction through the second mounting base 51, which helps to improve the reliability of the hopper assembly 100.

[0066] For example, the second limiting rod 50 extends in the vertical direction, and two second mounting seats 51 are respectively located at the upper and lower ends of the second limiting rod 50. The second limiting rod 50 can be used to push the workpiece 78 to move. The upper second mounting seat 51 is engaged with the outer side of the first preset cavity wall 11, and the lower second mounting seat 51 is engaged with the inner side of the first preset cavity wall 11. The second limiting rod 50 is located in the placement cavity 10 so that the second limiting rod 50 can push the workpiece 78 to move more conveniently. A part of the second limiting structure 5 extends beyond the first preset cavity wall 11 so that the operator can more conveniently contact the second limiting structure 5 and facilitate the operation of the movement of the second limiting structure 5.

[0067] like Figures 1-6 As shown, in some embodiments, the hopper assembly 100 further includes a brush structure 60, which is disposed at the top of the first limiting rod 30 and corresponds to the top of the placement cavity 10. The brush structure 60 includes a third mounting base 61 and bristles (not shown) disposed on the third mounting base 61. The third mounting base 61 is disposed on the side of the first limiting rod 30 facing away from the first preset cavity wall 11 in the first horizontal direction. The bristles extend beyond the first limiting rod 30 in the first horizontal direction towards the first preset cavity wall 11. At the end, brush bristles are provided between two adjacent first limiting rods 30; and / or, the hopper assembly 100 further includes: a blowing structure 62, the blowing structure 62 is disposed at the top of the first limiting rod 30, and the blowing structure 62 is disposed corresponding to the top of the placement cavity 10, the blowing structure 62 is disposed on the side of the first limiting rod 30 away from the first preset cavity wall 11 in the first horizontal direction, and the side of the blowing structure 62 facing the first preset cavity wall 11 forms a plurality of air outlets 63, and at least one air outlet 63 is provided between two adjacent first limiting rods 30. Exemplarily, the plurality of air outlets 63 of the blowing structure 62 can be spaced apart along the second horizontal direction; or, the plurality of air outlets 63 of the blowing structure 62 can be arranged in multiple rows and columns along the second horizontal direction and the vertical direction.

[0068] As can be seen, for the brush structure 60, the third mounting base 61 is located on the side of the first limiting rod 30 facing away from the first preset cavity wall 11 in the first horizontal direction, so that the third mounting base 61 does not easily interfere with the material picking and putting on of the bearing table 20. At the same time, the third mounting base 61 does not easily interfere with the normal operation of the first limiting rod 30. That is, when the first limiting rod 30 pushes the workpiece 78 toward the first preset cavity wall 11, there can still be a certain gap between the third mounting base 61 and the workpiece 78, so that the third mounting base 61 does not easily interfere with the first limiting rod 30 pushing the workpiece 78 to move. The brush structure 60 is set at the top of the placement cavity 10. Taking the end of the first limiting rod 30 facing the first preset cavity wall 11 as the boundary, the bristles can extend from the side of the boundary facing away from the first preset cavity wall 11 to the side of the boundary facing the first preset cavity wall 11, so that the bristles extend beyond the end of the first limiting rod 30 facing the first preset cavity wall 11 in the first horizontal direction, so that the bristles can more easily connect. When the hopper assembly 100 is used in the inspection equipment 200, it touches the workpiece 78. The hopper assembly 100 includes a feeding gripping assembly 106 (e.g., a robotic arm). The support platform 20 has multiple workpieces 78. The feeding gripping assembly 106 needs to transfer each workpiece 78 to the inspection. However, multiple workpieces 78 are prone to sticking when gripped. The feeding gripping assembly 106 may grip multiple workpieces 78 at once. By setting the brush structure 60, at least part of the bristles can be pressed on the uppermost workpiece 78. When the feeding gripping assembly 106 grips the workpiece 78, the bristles can brush off the multiple sticky workpieces 78, ensuring that the feeding gripping assembly 106 only grips one product, which is convenient for subsequent inspection of workpieces 78. Bristles are provided between two adjacent first limit rods 30, which can mean that bristles are provided between at least two adjacent second limit rods 30. For example, bristles are provided between any two adjacent first limit rods 30 to accommodate workpieces 78 of different sizes.

[0069] For the blowing structure 62, the blowing structure 62 is located on the side of the first limiting rod 30 away from the first preset cavity wall 11 in the first horizontal direction, so that the blowing structure 62 does not easily interfere with the material picking and unloading of the bearing table 20. At the same time, the blowing structure 62 does not easily interfere with the normal operation of the first limiting rod 30. That is, when the first limiting rod 30 pushes the workpiece 78 toward the first preset cavity wall 11, there can still be a certain gap between the blowing structure 62 and the workpiece 78, so that the blowing structure 62 does not easily interfere with the first limiting rod 30 pushing the workpiece 78 to move. The blowing structure 62 is set at the top of the placement cavity 10, and the blowing structure 62 faces the top of the placement cavity 10. A plurality of air outlets 63 are formed on one side of the first preset cavity wall 11, that is, the plurality of air outlets 63 can also be arranged corresponding to the top of the placement cavity 10, so that the blowing structure 62 can remove dust and particles from the surface of the workpiece 78, clean the workpiece 78, and facilitate the subsequent inspection of the workpiece 78; at least one air outlet 63 is provided between two adjacent first limiting rods 30, for example, at least one air outlet 63 is provided between at least two adjacent first limiting rods 30, or at least one air outlet 63 is provided between multiple first limiting rods 30, so that the cleaning range of the blowing structure 62 is larger and can be adapted to workpieces 78 of different sizes.

[0070] It is understood that at least one air vent 63 is provided between two adjacent first limiting rods 30, which can mean that at least two adjacent second limiting rods 30 are provided with air vent 63. For example, air vent 63 is provided between any two adjacent first limiting rods 30, so as to accommodate workpieces 78 of different sizes.

[0071] Therefore, when the hopper assembly 100 includes a brush structure 60 and a blowing structure 62, both the brush structure 60 and the blowing structure 62 are located at the top of the first limiting rod 30. Most of the brush structure 60 and the blowing structure 62 are located on the side of the first limiting rod 30 facing away from the first preset cavity wall 11 in the first horizontal direction. The brush structure 60 and the blowing structure 62 can be arranged at intervals in the second horizontal direction or arranged in the vertical direction, so that the brush structure 60 and the blowing structure 62 are less likely to interfere with each other, while also enriching the functions of the hopper assembly 100 and improving the practicality of the hopper assembly 100.

[0072] Furthermore, the brush structure 60 and / or the blowing structure 62 can move with the first limiting rod 30, which is used to push the workpiece toward the first preset cavity wall 11. The first limiting rod 30 can eventually be locked in the limiting position by the locking structure 4. In the limiting position, the workpiece 78 is sandwiched between the first limiting structure 3 and the first preset cavity wall 11. Then the brush structure 60 and / or the blowing structure 62 can achieve a matching position with the workpiece 78, so that the brush structure 60 and / or the blowing structure 62 can perform corresponding processing on the workpiece 78.

[0073] like Figures 1-6As shown, in some embodiments, at least one handle groove 16 is formed on the inner surface of the first preset cavity wall 11, the handle groove 16 penetrates the top surface of the first preset cavity wall 11, and the hopper assembly 100 also includes a brush structure 60 and / or a blowing structure 62. A brush structure 60 is disposed at the top of the first limiting rod 30 and is positioned corresponding to the top of the placement cavity 10. The brush structure 60 includes a third mounting base 61 and bristles disposed on the third mounting base 61. The third mounting base 61 is disposed on the side of the first limiting rod 30 facing away from the first preset cavity wall 11 in the first horizontal direction. The bristles extend beyond the end of the first limiting rod 30 facing the first preset cavity wall 11 in the first horizontal direction. Bristles are provided between two adjacent first limiting rods 30. A blowing structure 62 is disposed at the top of the first limiting rod 30 and is positioned corresponding to the top of the placement cavity 10. At least a portion of the blowing structure 62 is disposed on the side of the first limiting rod 30 facing away from the first preset cavity wall 11 in the first horizontal direction. A plurality of air outlets 63 are formed on the side of the blowing structure 62 facing the first preset cavity wall 11. At least one air outlet 63 is provided between two adjacent first limiting rods 30.

[0074] As can be seen, the handle groove 16 is formed on the inner surface of the first preset cavity wall 11. Most of the brush structure 60 and the blowing structure 62 are located on the side of the first limiting rod 30 away from the first preset cavity wall 11 in the first horizontal direction. That is, the brush structure 60 and the blowing structure 62 and the handle groove 16 are respectively located on both sides of the workpiece 78 in the first horizontal direction. When the worker takes out the workpiece 78 through the handle groove 16, it is not easily interfered with by the brush assembly and the blowing structure 62, so that the worker can take out the workpiece 78 more conveniently.

[0075] In addition, the hand groove 16 penetrates the top surface of the first preset cavity wall 11. Even if one side wall of the workpiece 78 abuts against the first preset cavity wall 11, there can still be a certain distance between the hand groove 16 and the workpiece 78, which makes it convenient for the staff to put their hands into the hand groove 16 and then take the workpiece 78 out of the support table 20, so that the staff can take out the workpiece 78 more conveniently.

[0076] like Figure 2 and Figure 4 As shown, in some embodiments, the support platform 20 is also provided with hand grooves 16 at both ends along the second horizontal direction. The hand grooves 16 penetrate the top surface of the support platform 20. When the workpiece 78 is placed on the support platform 20, there is still a certain gap between the workpiece 78 and the hand grooves 16, which makes it easier for the staff to put their hands in and take the workpiece 78 off the support platform 20 more conveniently.

[0077] like Figures 1-6As shown, in some embodiments, at least one handle groove 16 is formed on the inner surface of the first preset cavity wall 11. The handle groove 16 penetrates the top surface of the first preset cavity wall 11. The support structure 2 is vertically mounted on the hopper body 1. The support structure 2 can cooperate with the handle groove 16 so that the operator can take out more workpieces 78 at once. For example, the hopper assembly 100 is used as a feeding hopper. The support structure 2 can be raised to a certain height position, and the operator can reach the handle groove 16 to take out more or even all workpieces 78 at once. The first horizontal direction is perpendicular to the second horizontal direction. The hopper assembly 100 also includes a drive structure 70 and a position detection structure 74. The drive structure 70 is located on the hopper body 1 and outside the placement cavity 10. The drive structure 70 is connected to the support structure 2 to drive the support structure 2 to rise and fall. The position detection structure 74 is located on the hopper body 1 and is suitable for being triggered by a workpiece 78 placed on the support platform 20 and reaching a predetermined height. The position detection structure 74 communicates with the drive structure 70 and is spaced apart from the first preset cavity wall 11.

[0078] As can be seen, the drive structure 70 can drive the support platform 20 to rise and fall. The drive structure 70 can determine the quantity of workpieces 78 on the support platform 20 based on the detection result of the position detection structure 74, so as to control the rise and fall of the support platform 20.

[0079] Taking the hopper assembly 100 as a loading hopper as an example, multiple workpieces 78 can be placed on the support platform 20. The drive structure 70 drives the support platform 20 to rise. When the workpiece 78 placed on the support platform 20 rises to a predetermined height, the positioning detection structure 74 is triggered, and the drive structure 70 stops driving the support platform 20 to rise. When the hopper assembly 100 is used for the detection device 200, the hopper assembly 100 includes a loading gripper assembly 106 (e.g., a robotic arm). After the loading gripper assembly 106 removes the first workpiece 78, the positioning detection structure 74 is no longer triggered, and the drive structure 70 continues to drive the support platform 20 to rise. When the second workpiece 78 placed on the support platform 20 triggers the positioning detection structure 74, the drive structure 70 stops driving the support platform 20 to rise, and the loading gripper assembly 106 removes the workpiece again. This cycle continues. It can be understood that the control logic of the hopper assembly 100 as a unloading hopper can be reversed.

[0080] By setting up a positioning detection structure 74, the positioning detection structure 74 can detect whether the workpiece 78 is in position. The detection result of the positioning detection structure 74 controls the operation of the drive structure 70. After the workpiece 78 on the support platform 20 is removed, the support platform 20 is driven to rise, or after the workpiece 78 is placed on the support platform 20, the support platform 20 is driven to fall, so that the uppermost workpiece 78 on the support platform 20 maintains the same height. This makes it easier for the feeding gripping component 106 to pick up and put down the workpiece 78 at the same height, so that the support platform 20 can automatically rise and fall to a position suitable for loading and unloading the workpiece 78, thereby improving the automation level of loading and unloading. On the one hand, it can further facilitate the feeding gripping component 106 to pick up and put down the workpiece 78. On the other hand, it can simplify the control logic of the feeding gripping component 106, making it easier to cooperate with the feeding gripping component 106 and avoiding damage to the workpiece 78 due to improper cooperation with the feeding gripping component 106, thus improving the reliability of loading and unloading.

[0081] In addition, the drive structure 70 is located outside the placement cavity 10 so that the drive structure 70 will not occupy additional space in the placement cavity 10, providing more operating space for the picking and placing of the workpiece 78; the position detection structure 74 is spaced apart from the first preset cavity wall 11, for example, the position detection structure 74 is located on both sides of the placement cavity 10 in the second horizontal direction so that the position detection structure 74 does not easily interfere with the picking and placing of the workpiece 78.

[0082] For example, the positioning detection structure 74 includes a transmitter 75 and a receiver 76, which are located on the two side walls of the placement cavity 10 in the second horizontal direction. When the workpiece 78 has not reached the preset height position, the receiver 76 can receive the rays emitted by the transmitter 75, thereby controlling the lifting and lowering of the support platform 20 by controlling the drive structure 70. When the workpiece 78 reaches the preset height position, the workpiece 78 can block the rays emitted by the transmitter 75. At this time, the receiver 76 cannot receive the rays emitted by the transmitter 75, thereby determining that the workpiece 78 has reached the preset height position.

[0083] like Figures 1-3As shown, in some embodiments, the supporting structure 2 further includes a first support member 22 and a second support member 23. Multiple first support members 22 are spaced apart along a second horizontal direction and are all supported on the lower side of the support platform 20. The multiple first support members 22 are offset from the first limiting rod 30. The second support member 23 is located on the side of the support platform 20 away from the first preset cavity wall 11 in the first horizontal direction, and is located on the side of the multiple first limiting rods 30 opposite to the first preset cavity wall 11. The second support member 23 is connected to each first support member 22. The two ends of the second support member 23 in the second horizontal direction are respectively slidably engaged with the corresponding cavity wall of the placement cavity 10 through a third guide rail structure 24 (for example, one end of the second support member 23 in the second horizontal direction is slidably engaged with the second preset cavity wall 13 through the third guide rail structure 24). The second support member 23 is slidably engaged with the other end of the placement cavity 10 opposite to the second preset cavity wall 13 via the third guide rail structure 24. The placement cavity 10 is open on one side corresponding to the second support member 23. Or, the cavity wall of the placement cavity 10 on one side in the second horizontal direction is the second preset cavity wall 13. The driving structure 70 is located on the side of the second preset cavity wall 13 away from the placement cavity 10. The side of the second preset cavity wall 13 away from the placement cavity 10 is also provided with a first limiting member 90 and a second limiting member 91 spaced apart in the vertical direction. The bearing structure 2 is provided with a trigger member 25. Each of the first limiting member 90 and the second limiting member 91 is adapted to cooperate with the trigger member 25 so that both the first limiting member 90 and the second limiting member 91 cooperate with the driving structure 70 to limit the movement range of the bearing structure 2.

[0084] When the bearing structure 2 includes a first support member 22 and a second support member 23, the multiple first support members 22 are all supported on the lower side of the bearing platform 20, and the second support member 23 and the multiple first support members 22 can form a triangular support, which facilitates the improvement of the bearing capacity of the bearing platform 20, so that the bearing platform 20 can place more workpieces 78 without easily causing large deformation; the first support member 22 and the first limiting rod 30 are staggered, for example, the first support member 22 and the first limiting rod 30 are spaced apart in the second horizontal direction, so that the first support member 22 does not easily affect the first limiting rod 30 along the first horizontal direction. The second support 23 is located on the side of the support platform 20 away from the first preset cavity wall 11 in the first horizontal direction, providing a larger operating space for the loading and unloading of materials by the support platform 20, so that the second support 23 is less likely to interfere with the loading and unloading operations of the support platform 20; the second support 23 is located on the side of the plurality of first limiting rods 30 away from the first preset cavity wall 11, so that when the first limiting rods 30 move towards the first preset cavity wall 11 in the first horizontal direction, the second support 23 is less likely to interfere with the movement of the first limiting rods 30, which facilitates the improvement of material handling efficiency. The reliability of the storage assembly 100; the second support member 23 is connected to the first support member 22, and the two ends of the second support member 23 in the second horizontal direction are respectively connected to the corresponding cavity walls of the placement cavity 10. Through the sliding engagement of the third guide rail structure 24, the multiple first support members 22 can move together with the second support member 23 in the vertical direction. By providing the third guide rail structure 24 between the second support member 23 and the cavity wall, the second support member 23 and the multiple first support members 22 can move along the second guide rail structure 52 in the vertical direction, so that the second support member 23 and the multiple first support members 22 can move along the second guide rail structure 52. The movement path of component 2 is more clearly defined, which facilitates the improvement of the reliability of the hopper assembly 100; the placement cavity 10 is open at one end corresponding to the second support member 23, so that when the second support member 23 moves in the vertical direction, it is not easily disturbed by the cavity wall of the placement cavity 10. At the same time, the open design of the placement cavity 10 allows the staff to more easily observe and access the components inside the placement cavity 10, which facilitates the improvement of the maintenance efficiency of the hopper assembly 100. Moreover, the open design of the placement cavity 10 helps to reduce the number of parts in the hopper assembly 100, which helps to reduce the manufacturing cost of the hopper assembly 100. For example, as Figure 2 As shown, there are three first support members 22, and each first support member 22 is roughly L-shaped.

[0085] When the bearing structure 2 is provided with a trigger 25, the trigger 25 can move along the bearing structure 2 in the vertical direction. The first limiting member 90 and the second limiting member 91 are spaced apart in the vertical direction. Each of the first limiting member 90 and the second limiting member 91 is adapted to cooperate with the trigger 25. During the process of the trigger 25 moving along the bearing structure 2 in the vertical direction, the trigger 25 can trigger the first limiting member 90 and the second limiting member 91 respectively, so that the first limiting member 90 and the second limiting member 91 cooperate with the drive structure 70 to limit the movement range of the bearing structure 2. When the trigger 25 triggers the first limiting member 90 and the second limiting member 91, it can transmit the trigger information to the drive structure 70, and the drive structure 70 will not continue to operate, thereby realizing the control of the movement range of the bearing structure 2 and improving the reliability of the hopper assembly 100.

[0086] For example, the first limiting member 90 is located at the extreme position of the downward movement of the bearing structure 2, and the second limiting member 91 is located at the extreme position of the upward movement of the bearing structure 2. After the trigger member 25 triggers the first limiting member 90 and the second limiting member 91, it can transmit the trigger information to the drive structure 70. The drive structure 70 knows that the bearing structure 2 has moved to the extreme position, and the drive structure 70 can stop working so that the bearing structure 2 is less likely to move excessively, which helps to reduce interference between the bearing component and other components and improve the reliability of the hopper assembly 100.

[0087] It is understood that each of the first limiting member 90 and the second limiting member 91 is adapted to cooperate with the trigger member 25, and may include: the first limiting member 90 and the second limiting member 91 being a stop, when the first limiting member 90 or the second limiting member 91 cooperates with the trigger member 25, the first limiting member 90 or the second limiting member 91 can increase the moving resistance of the trigger member 25, thereby increasing the output current of the drive structure 70, thereby determining that the trigger member 25 has moved to the position of the first limiting member 90 or the position of the second limiting member 91; or the first limiting member 90 and the second limiting member 91 being a sensor, when the first limiting member 90 or the second limiting member 91 cooperates with the trigger member 25, the trigger member 25 will block the aforementioned sensor, thereby determining that the trigger member 25 has moved to the position of the first limiting member 90 or the position of the second limiting member 91.

[0088] like Figure 2 and Figure 4 As shown, in some embodiments, a portion of the support platform 20 is recessed downward to form a groove, and the hopper assembly 100 also includes a sensor 77, which is disposed in the groove. The sensor 77 can be used to detect whether there is a workpiece 78 on the support platform 20.

[0089] For example, sensor 77 communicates with an alarm component (e.g., a buzzer). When sensor 77 detects that there is no workpiece 78 on the support platform 20, sensor 77 can transmit the detection information to the alarm component. The alarm component reminds the operator that there is no workpiece 78 in the hopper assembly 100 (e.g., the alarm component emits a light or sound to remind the operator), so that the operator can replenish the workpiece 78 in the hopper assembly 100 in a timely manner. Moreover, when the hopper assembly 100 is used for the detection device 200, sensor 77 communicates with the controller of the detection device 200. When sensor 77 detects that there is no workpiece 78 on the support platform 20, sensor 77 can transmit the detection information to the controller, and the detection device 200 performs corresponding operations. For example, the detection device 200 includes a feeding gripping component 106, and the feeding gripping component 106 no longer performs a material picking operation on this hopper assembly 100.

[0090] like Figure 1 and Figure 2 As shown, in some embodiments, one side wall of the placement cavity 10 in the second horizontal direction is a second preset cavity wall 13, and the driving structure 70 is disposed on the side of the second preset cavity wall 13 opposite to the placement cavity 10. The driving structure 70 includes a drive motor 71 and a transmission mechanism 72, and the transmission mechanism 72 can be a belt drive (e.g., Figure 1 As shown, the transmission mechanism 72 includes a belt 73, a chain drive, or a gear drive mechanism, etc. The bearing structure 2 includes multiple first support members 22, second support members 23, connecting members 26, and trigger members 25. The multiple first support members 22 are spaced apart along the second horizontal direction and are all supported on the lower side of the bearing platform 20. The second support members 23 are located on the side of the bearing platform 20 away from the first preset cavity wall 11 in the first horizontal direction. The second support members 23 are connected to each first support member 22. One end of the connecting member 26 is connected to the second support member 23, and the other end of the connecting member 26 is connected to the belt 73. 6 is spaced apart from the second preset cavity wall 13 in the second horizontal direction. The trigger 25 is connected to the connector 26. Then, multiple first support members 22, second support members 23, connectors 26 and trigger 25 can move together with belt 73 in the vertical direction. The side of the second preset cavity wall 13 away from the placement cavity 10 is also provided with a first limiting member 90 and a second limiting member 91 spaced apart in the vertical direction. During the movement of multiple first support members 22, second support members 23 and connectors 26, the trigger 25 can trigger the first limiting member 90 and the second limiting member 91 respectively, thereby controlling the movement range of the bearing structure 2.

[0091] like Figure 3 and Figure 5As shown, in some embodiments, the hopper assembly 100 further includes a cover 97, which covers the side of the second preset cavity wall 13 away from the placement cavity 10. A receiving cavity is also formed between the cover 97 and the second preset cavity wall 13. The receiving cavity is used to place the drive structure 70, the first limiting member 90 and the second limiting member 91, so that the staff cannot directly contact the drive structure 70, the first limiting member 90 and the second limiting member 91, so that the drive structure 70, the first limiting member 90 and the second limiting member 91 are not easily affected by external foreign objects, thereby improving the reliability of the hopper assembly 100.

[0092] like Figures 1-9 As shown, in some embodiments, the hopper assembly 100 further includes: a base 92, a trigger structure 93, and a third limiting structure 94. The hopper body 1 and the base 92 are pulled together in a second horizontal direction, and the hopper body 1 has a predetermined position during the pulling process. The trigger structure 93 is configured to be triggered when the hopper body 1 moves to the predetermined position. The third limiting structure 94 has a limiting state and a releasing state. In the limiting state, the third limiting structure 94 pushes upward against the bottom wall 12 of the placement cavity 10 to restrict the movement of the hopper body 1 relative to the base 92. In the releasing state, the third limiting structure 94 avoids the hopper body 1. The third limiting structure 94 communicates with the trigger structure 93, and the third limiting structure 94 is configured to switch to the limiting state when the trigger structure 93 is triggered.

[0093] As can be seen, when the third limiting structure 94 is in the released state, the third limiting structure 94 can be spaced apart from the bottom wall 12 of the placement cavity 10 to allow the hopper body 1 to move relative to the base 92 in the second horizontal direction. After the hopper body 1 is pushed to the predetermined position in the second horizontal direction, the trigger structure 93 can be triggered by the hopper body 1 to determine that the hopper body 1 has been pushed into place. At this time, the third limiting structure 94 can switch from the released state to the limiting state. The third limiting structure 94 pushes upward against the bottom wall 12 of the placement cavity 10 to restrict the movement of the hopper body 1 relative to the base 92 in the second horizontal direction, so as to make the setting position of the hopper body 1 more stable.

[0094] For example, when the hopper assembly 100 is used as a feeding hopper, after all the workpieces 78 placed on the support platform 20 have been picked up, the hopper body 1 can be pulled out along the second horizontal direction to provide a larger operating space for the staff to put materials onto the support platform 20. After the materials are put onto the support platform 20, the hopper body 1 can be pushed to a preset position along the second horizontal direction. The trigger structure 93 can be triggered by the hopper body 1. At this time, the third limiting structure 94 can switch from the release state to the limiting state. The third limiting structure 94 pushes upward against the bottom wall 12 of the placement cavity 10 to restrict the movement of the hopper body 1 relative to the base 92 in the second horizontal direction, so that the setting position of the hopper body 1 is more stable and facilitates the subsequent picking operation of the workpieces 78 on the support platform 20.

[0095] The bottom of the cavity bottom wall 12 is provided with a stop block 95, and the bottom surface of the stop block 95 is provided with anti-slip texture. In the limited state, the third limiting structure 94 pushes against the anti-slip texture. The stop block 95 protruding from the cavity bottom wall 12 reduces the upward pushing distance of the third limiting structure 94, so that the third limiting structure 94 can better contact the stop block 95. At the same time, the stop of the third limiting structure 94 against the anti-slip texture can increase the frictional force when the third limiting structure 94 and the stop block 95 move relative to each other, so that the cooperation between the third limiting structure 94 and the stop block 95 is more stable, so as to better limit the movement of the hopper body 1 relative to the base 92 in the second horizontal direction, and improve the reliability of the hopper assembly 100. Exemplarily, the third limiting structure 94 includes a cylinder, and the setting of the stop block 95 helps to reduce the requirements of the cylinder stroke.

[0096] like Figure 7 As shown, in some embodiments, a fourth slide rail structure 17 is provided between the hopper body 1 and the base 92. The hopper body 1 and the base 92 slide and cooperate along the second horizontal direction through the fourth slide rail structure 17. By setting the fourth slide rail structure 17, the hopper body 1 can move relative to the base 92 along the fourth slide rail structure 17 in the second horizontal direction, so that the movement path of the hopper body 1 is clearer and the reliability of the hopper assembly 100 is improved.

[0097] like Figure 8 and Figure 9 As shown, in some embodiments, the hopper body 1 also has a hopper panel, which is located on the side of the placement cavity 10 away from the second preset cavity wall 13 in the second horizontal direction. The side of the hopper panel away from the placement cavity 10 has a grip groove 99. By setting the grip groove 99, the operator can more conveniently control the movement of the hopper body 1 along the second horizontal direction, which simplifies the pulling process of the hopper body 1.

[0098] like Figure 1 and Figure 4As shown, in some embodiments, the hopper assembly 100 further includes a cable chain 98, in which all the pipes and wiring harnesses of the hopper assembly 100 are placed. One end of the cable chain 98 is connected to the hopper body 1, and the other end of the cable chain 98 is connected to the base 92. When the hopper body 1 moves relative to the base 92 in the second horizontal direction, the pipes and wiring harnesses in the hopper assembly 100 are not easily affected, which helps to improve the reliability of the hopper assembly 100.

[0099] The detection device 200 according to the second aspect of the present invention includes the hopper assembly 100 according to the first aspect of the present invention.

[0100] According to the detection equipment 200 of this utility model embodiment, the above-mentioned hopper assembly 100 can realize the neat placement of workpieces 78, so that the material picking and unloading of the detection equipment 200 can be made simpler. By adopting this hopper assembly 100, the working efficiency of the detection equipment 200 can be improved.

[0101] In some embodiments, such as Figure 10 As shown, the testing equipment 200 includes a first feeding bin 101, a first conveying platform 103, a second conveying platform 104, a tilting platform 105, and a feeding gripping assembly 106. The first conveying platform 103 is located on one side of the first feeding bin 101 in a first horizontal direction and is used to convey the workpiece 78 to a first image acquisition position along a second horizontal direction. The second conveying platform 104 is spaced apart on the side of the first conveying platform 103 away from the first feeding bin 101 and is used to convey the workpiece 78 to a second image acquisition position along a second horizontal direction. The tilting platform 105 is located between the first conveying platform 103 and the second conveying platform 104, and is rotatable about an axis extending along the second horizontal direction. The tilting platform 105 is used to tilt the workpiece 78 onto the second conveying platform 104. The first feeding bin 101 can be a bin assembly described in the first aspect of this application above; however, the first feeding bin 101 may not be the bin assembly described above.

[0102] The feeding gripping assembly 106 is movable along a first horizontal direction and has a first position and a second position. The feeding gripping assembly 106 includes a first gripper 1061 and a second gripper 1062 arranged along the first horizontal direction. In the first position, the first gripper 1061 is adapted to grip the workpiece 78 on the first conveying platform 103 and the second gripper 1062 is adapted to grip the workpiece 78 in the first feeding bin 101. In the second position, the first gripper 1061 is adapted to place the gripped workpiece 78 on the flipping platform 105 and the second gripper 1062 is adapted to place the gripped workpiece 78 on the first conveying platform 103.

[0103] For example, the flipping platform 105 may have a carrying position and a releasing position. In the carrying position, the flipping platform 105 may be used to receive the workpiece 78, while in the releasing position, the flipping platform 105 may release the workpiece 78 on it to the second conveying platform 104. Each of the first conveying platform 103 and the second conveying platform 104 has an initial position and a target position. Each of the first conveying platform 103 and the second conveying platform 104 may travel back and forth between the initial position and the target position. The target position corresponds to the first image acquisition position / second image acquisition position. The initial position may be used to receive the workpiece 78 or transfer the workpiece 78.

[0104] For example, the loading gripping assembly 106 grips and releases the workpiece 78 by vacuum adsorption. In the first position, the first gripper 1061 is vertically opposite to the first conveying platform 103 so that the first gripper 1061 can adsorb and grip the workpiece 78 on the first conveying platform 103, and the second gripper 1062 is opposite to the first loading bin 101 so that the second gripper 1062 can adsorb and grip the workpiece 78 in the first loading bin 101. In the second position, the first gripper 1061 is opposite to the tilting platform 105 in the bearing position so that the first gripper 1061 can place the gripped workpiece 78 on the tilting platform 105, and the second gripper 1062 is opposite to the first conveying platform 103 so that the second gripper 1062 can place the gripped workpiece 78 on the first conveying platform 103. It can be understood that the workpiece 78 gripped by the first gripper 1061 on the first conveying platform 103 can be the workpiece 78 that has been captured by the first image acquisition position, or in other words, the workpiece 78 gripped by the first gripper 1061 has completed the image acquisition of its upper surface. After the first gripper 1061 transfers the workpiece 78 on the first conveying platform 103 to the flipping platform 105, the flipping platform 105 transfers the workpiece 78 to the second conveying platform 104 by flipping. Then the second conveying platform 104 can transfer the workpiece 78 to the second image acquisition position to acquire the image of the lower surface of the workpiece 78. As can be seen, by moving the feeding gripper 106 between the first and second positions, the workpiece 78 on the first feeding bin 101 can be transferred to the first conveying platform 103 by the second gripper 1062, while the workpiece 78 on the first conveying platform 103 can be transferred to the flipping platform 105 by the first gripper 1061. This allows for the simultaneous handling of two workpieces 78, which improves the transfer efficiency of the workpiece 78, reduces equipment waiting time, improves the overall inspection efficiency, and enables the inspection process to be carried out continuously and efficiently. At the same time, the flipping platform 105 can flip the workpiece 78 up and down, enabling sequential inspection of the upper and lower surfaces of the workpiece 78, thus improving the level of inspection automation.

[0105] Furthermore, the testing equipment 200 also includes a second feeding bin 102, which is arranged sequentially with the first feeding bin 101 along a first horizontal direction. The second feeding bin 102 is located on the side of the first feeding bin 101 away from the first conveying platform 103. Thus, the second feeding bin 102 and the first conveying platform 103 are respectively located on opposite sides of the first feeding bin 101 in the first horizontal direction. At this time, the feeding gripping assembly 106 also has a third position, in which the second gripper 1062 is adapted to grip the workpiece 78 in the second feeding bin 102. For example, in the third position, the second gripper 1062 is vertically opposite to the second feeding bin 102. The second feeding bin 102 can be a bin assembly described in the first aspect of this application above. Of course, the second feeding bin 102 may not be the bin assembly described above.

[0106] For example, the loading gripper assembly 106 first moves to the third position, and the second gripper 1062 grips the workpiece 78 in the second loading bin 102; then, the loading gripper assembly 106 moves to the second position, and the second gripper 1062 places the workpiece 78 on the first conveying platform 103, which moves the workpiece 78 toward the first image acquisition position; simultaneously, the loading gripper assembly 106 moves to the first position, the second gripper 1062 grips the workpiece 78 in the first loading bin 101, and the first gripper 1061 grips the workpiece 78 returning from the first image acquisition position on the first conveying platform 103 (the workpiece 78 has completed image acquisition of its upper surface); then, the loading gripper assembly 106 moves to the second position. The second gripper 1062 places the workpiece 78 on the first conveying platform 103, and the first gripper 1061 places the workpiece 78 on the flipping platform 105. The first conveying platform 103 moves the workpiece 78 toward the first image acquisition position, and the flipping platform 105 flips the workpiece 78 onto the second conveying platform 104. The second conveying platform 104 moves the workpiece 78 toward the second image acquisition position. Then, the loading gripping assembly 106 moves back to the first position, the second gripper 1062 grabs the workpiece 78 in the first loading bin 101, and the first gripper 1061 grabs the workpiece 78 that has returned from the first image acquisition position on the first conveying platform 103 (the workpiece 78 has completed the image acquisition of its upper surface), and so on.

[0107] Furthermore, the testing equipment 200 also includes at least one unloading bin 107, which is located on the side of the second conveying platform 104 away from the first conveying platform 103. In the first horizontal direction, the second conveying platform 104 is located between the unloading bin 107 and the first conveying platform 103. The testing equipment 200 also includes an unloading gripping assembly 108, which is movable along the first horizontal direction and is used to transport the workpiece 78 on the second conveying platform 104 to the corresponding unloading bin 107. At least one of the unloading bins 107 can be a bin assembly described in the first aspect of this application; however, all unloading bins 107 may not be the aforementioned bin assembly.

[0108] For example, there can be one or more unloading bins 107, and multiple unloading bins 107 can be arranged sequentially along the first horizontal direction, which is beneficial to increasing the unloading storage space; the unloading gripping component 108 grips and releases the workpiece 78 by vacuum adsorption. For example, the multiple unloading bins 107 include a good product bin and a defective product bin. After the workpiece 78 passes through the first image acquisition position and the second image acquisition position, the detection device 200 can determine whether the workpiece 78 is qualified. Qualified workpieces 78 are transported from the second conveying platform 104 to the good product bin by the unloading gripping component 108, and unqualified workpieces 78 are transported from the second conveying platform 104 to the defective product bin by the unloading gripping component 108, thereby realizing classified unloading.
