Description

Technical Field

[0001] This application relates to the field of testing equipment, and in particular to a track for optical testing equipment and an optical testing device. Background Technology

[0002] Optical inspection equipment (automatic optical inspection equipment) is an automated inspection system based on optical imaging and image processing technology. It is widely used in fields such as electronics manufacturing, automobiles, and medical equipment. It is an important inspection tool and efficiency improvement tool for ensuring product quality in the electronics manufacturing industry.

[0003] In the process of realizing this invention, the inventors discovered that the prior art has at least the following problems: the overall width of the track in the existing optical inspection equipment is large, which occupies the board size of the equipment. Especially in multi-channel optical inspection equipment, the number of tracks increases, which leads to a further reduction in the board size within the limited equipment space, affecting the compatibility of the equipment with various board sizes. Utility Model Content

[0004] Based on this, the purpose of this application is to provide a track for optical inspection equipment and an optical inspection device. The track for the optical inspection device places a pressure plate drive source directly above or below a support. The pressure plate drive source drives a swinging component to swing, and a pressure plate fixing component and a pressure plate connected to the lower end of the swinging component swing along with the swinging component, thereby opening and closing the pressure plate. The opening and closing of the pressure plate allows for the fixing and loosening of the product to be tested, facilitating optical inspection. Compared with existing technical solutions, the technical solution of this application reduces the track width. Within the same size optical inspection device, the size of the through plate between the two tracks is increased, allowing for the placement of wider products to be tested. It has the advantages of compact size and high space utilization.

[0005] An optical inspection device track includes a bracket, a conveying unit, and a pressure plate unit. The conveying unit is fixed on the bracket and is used to convey the product to be tested from one end of the bracket to the other end. The pressure plate unit includes a pressure plate drive source and a pressure plate. The pressure plate drive source is mounted on the bracket, and all or part of the orthographic projection of the pressure plate drive source falls within the orthographic projection of the bracket. The pressure plate is lifted or pressed down under the drive of the pressure plate drive source.

[0006] The optical inspection equipment described in this application uses a track with a pressure plate drive source positioned directly above or below the support. The pressure plate drive source drives the opening and closing of the pressure plate, thereby fixing and releasing the product under test, facilitating optical inspection. Compared to existing technologies, this application's solution reduces the track width. Within the same size optical inspection equipment, the clearance between the two tracks is increased, allowing for the placement of wider products under test. This results in a compact design and high space utilization.

[0007] Furthermore, the system also includes a limiting unit mounted on the bracket. The pressure plate unit includes two pressure plate driving sources, and the limiting unit is located between the two pressure plate driving sources. The limiting unit is used to confine the product under test within the test area that the imaging component can detect. This solution, by placing the limiting unit between the two pressure plate driving sources, effectively positions the pressure plate driving sources outside the test area, preventing them from obstructing the light source and thus ensuring the detection effect.

[0008] Furthermore, the limiting unit includes a blocking limiting part or a control limiting part. The blocking limiting part includes a blocking drive source and a blocking block. The blocking drive source is mounted on the bracket, and the blocking block enters or leaves the movement path of the product under test under the drive of the blocking drive source. The control limiting part is used to control the movement and stop of the conveying unit. The blocking limiting part physically blocks the product under test by inserting a blocking block into the movement path of the product under test. The control limiting part controls the position of the product under test by controlling the movement and stop of the conveying unit. One of the above two methods can be selected to limit the product under test to the test area, ensuring that the product under test can be completely detected.

[0009] Furthermore, the blocking drive source is mounted on the bracket, either above or below the track plate of the bracket. The output end of the blocking drive source faces the inside of the bracket and is tilted towards the product under test. One end of the blocking block is fixed to the output end of the blocking drive source. The inside of the bracket is the side of the bracket closest to the product under test. The fact that the output end of the blocking drive source faces the inside of the bracket and is tilted towards the product under test helps to reduce the track width and also enables the blocking of irregularly shaped products under test. Furthermore, it minimizes the movement path of the blocking block, improving the efficiency of the blocking process.

[0010] Furthermore, the pressure plate unit also includes a swinging component and a pressure plate fixing component. The middle part of the swinging component is movably connected to the bracket, the end of the swinging component away from the bracket is movably connected to the output end of the pressure plate driving source, the end of the swinging component near the bracket is fixed to the pressure plate fixing component, one end of the pressure plate is fixed to the pressure plate fixing component, and the other end of the pressure plate extends towards the side of the product to be tested. By pushing and pulling the end of the swinging component away from the bracket through the pressure plate driving source, the swinging component is oscillated, thereby driving the pressure plate fixing component and the pressure plate to oscillate, so as to make the pressure plate press down on or release the product to be tested. Moreover, the pressure plate fixing component is set on the outside of the bracket, that is, one end of the pressure plate is set on the outside of the bracket, the other end of the pressure plate is set on the inside of the bracket, and the pressure plate spans the bracket, realizing space reuse in the track width direction with the pressure plate driving source, which is beneficial to further reduce the track width.

[0011] Furthermore, the pressure plate unit also includes a limiting part, which is disposed between the pressure plate drive source and the swing member. The limiting part is either a traction member located at the end of the swing member away from the bracket, or a support member located at the end of the swing member closer to the bracket. The limiting part is used to limit the swing amplitude of the swing member. When the limiting part is a traction member located at the end of the swing member away from the bracket, the traction member will provide a traction force to pull the swing member inward when the output end of the pressure plate drive source moves outward, thereby limiting the swing amplitude of the swing member. When the limiting part is a support member located at the end of the swing member closer to the bracket, when the output end of the pressure plate drive source moves outward to a certain extent, the support member will press against the swing member, thereby limiting the swing amplitude of the swing member and thus limiting the lifting height of the pressure plate to avoid damaging the imaging component.

[0012] Furthermore, the pressure plate unit also includes a first base, which is installed between the bracket and the pressure plate drive source. The limiting part is a support member. The support member is detachably installed on the outer side of the first base, or the support member is provided to pass through the first base along the driving direction of the pressure plate drive source and protrude from the outer side of the first base. The outer side of the first base is the side of the first base facing away from the product to be tested. Limiting the swing amplitude of the swinging member, thereby limiting the height of the pressure plate, facilitates bringing the light source closer to the product, making the illumination on the product more uniform, and improving the accuracy of the test.

[0013] Furthermore, the limiting part includes a limiting screw and a limiting nut. The limiting screw extends from the inner side of the first base to the outer side of the pressure plate drive source. One end of the limiting screw protrudes from the outer side of the first base and is located between the outer side of the pressure plate drive source and the swing member. The limiting nut is threadedly connected to the limiting screw located between the pressure plate drive source and the swing member. By tightening the limiting nut, the length of the limiting screw protruding from the outer side of the pressure plate drive source can be adjusted, making the swing amplitude of the swing member adjustable. This allows for flexible adjustment of the height of the pressure plate, facilitating the adjustment of the distance between the light source and the product according to different products and light sources, thus achieving optimal lighting effects.

[0014] Furthermore, the conveying unit includes a track drive source, and the support includes a track plate and two fixed seats below the track plate. One fixed seat has an accommodating space, and the other fixed seat has a track drive source for the conveying unit. The accommodating space can accommodate the track drive source. By setting the track drive source on one fixed seat and setting an accommodating space on the other fixed seat to cooperate with the track drive source, when the track is applied to a dual-track optical inspection device with multiple channels, such as four tracks, the two middle tracks can be arranged in opposite directions. That is, the fixed seat with the track drive source on one track and the fixed seat with the accommodating space on the other track are located at the same end. Therefore, when the two middle tracks are close to each other, the track drive sources of both tracks can pass through the accommodating space of the other track, so that the distance between the two middle tracks is not limited by the track drive source, thus making the distance between the two middle tracks closer. In optical inspection devices of the same size, products with a larger width can be inspected.

[0015] Furthermore, the conveying unit includes a track drive source, a transmission assembly, and a conveying assembly. The track drive source is fixed to the outer side of the bracket, and its output end extends through the bracket. Both the transmission assembly and the conveying assembly are located inside the bracket. The track drive source drives the transmission assembly and is driveably connected to it. The conveying assembly is driveably connected to the transmission assembly and is used to convey the product under test. A section of the conveying assembly near the top of the bracket extends along the direction of the bracket's extension. The track drive source drives the transmission assembly, which in turn drives the conveying assembly to convey the product under test.

[0016] This application also provides an optical inspection device, including a track for any of the optical inspection devices described above.

[0030] It should be understood that the embodiments of this application are not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from their scope. The scope of the embodiments of this application is limited only by the appended claims.

[0031] Existing optical inspection equipment has a large overall track width, which occupies the equipment's guide plate size. This is especially true in dual-track optical inspection equipment, where excessive guide plate size is used, leading to insufficient guide plate size.

[0032] Based on this, the purpose of this application is to provide a track for an optical inspection device, in which part or all of the pressure plate drive source is arranged above or below the bracket. The pressure plate drive source drives the opening and closing of the pressure plate, thereby fixing and releasing the product to be tested, facilitating optical inspection. Compared with existing technical solutions, the technical solution of this application, in the track width direction, achieves space reuse between at least a portion of the pressure plate drive source and the bracket, reducing the track width. Within the same size optical inspection device, the size of the through plate between the two tracks is increased, allowing for the placement of wider products to be tested. It has the advantages of compact size and high space utilization.

[0033] It should be noted that the optical inspection equipment of this application typically uses two parallel tracks together, with the product to be tested placed between the two tracks. For any track, the side facing the product to be tested is the inner side, and the side facing away from the product to be tested is the outer side.

[0034] This application provides a track for an optical inspection device; please refer to [link / reference]. Figure 1 and Figure 2 The device includes a support 1, a conveying unit 2, and a pressure plate unit 3. The conveying unit 2 is fixed on the support 1 and is used to convey the product to be tested (the product in this embodiment is a PCB board) from one end of the support 1 to the other end. The pressure plate unit 3 includes a pressure plate driving source 306 and a pressure plate 310. The pressure plate driving source 306 is mounted on the support 1. In the vertical direction, all or part of the orthographic projection of the pressure plate driving source 306 falls within the orthographic projection of the support 1 to avoid or reduce the influence of the pressure plate driving source 306 on the width of the track used for optical inspection equipment. The pressure plate 310 is lifted or pressed down under the drive of the pressure plate driving source 306 to loosen or press the product to be tested located on the conveying unit 2.

[0035] The optical inspection equipment track of this application embodiment has a pressure plate drive source positioned above or below a support. The output direction of the pressure plate drive source can be opposite to the product under test or parallel to the conveying direction of the product under test, depending on the size of the drive source itself or actual needs. The opening and closing of the pressure plate is driven by the extension and retraction of the pressure plate drive source, thereby fixing and releasing the product under test, facilitating optical inspection. Compared with existing technical solutions, the technical solution of this application reuses at least a portion of the pressure plate drive source with the support in the track width direction, reducing the track width. Within the same size optical inspection equipment, the size of the through plate between the two tracks is increased, allowing for the placement of wider products under test. It has the advantages of compact size and high space utilization. In other embodiments, the output direction of the pressure plate drive source can also be set towards the product under test. Specifically, the pressure plate drive source is mounted on the support, and the pressure plate is located between the pressure plate drive source and the product under test. The output end of the pressure plate drive source is set towards the product under test. The pressure plate drive source drives the pressure plate to lift or press down to release or press the product under test located on the conveying unit.

[0036] As an alternative implementation method, please refer to further information. Figure 6 The track for the optical inspection equipment also includes a limiting unit 4, which is mounted on the bracket 1. The pressure plate unit 3 includes two pressure plate drive sources 306, and the limiting unit 4 is located between the two pressure plate drive sources 306. The limiting unit 4 is used to restrict the product under test within the test area that the imaging component can detect. By placing the limiting unit between the two pressure plate drive sources, this solution places the pressure plate drive sources outside the test area, avoiding obstruction of the light source by the pressure plate drive sources, thereby ensuring the detection effect.

[0037] Based on the above solution, please refer to the following as an optional implementation method: Figure 7 The limiting unit 4 employs a blocking limiting part, which includes a second base 401, a blocking drive source 402, and a blocking block 403. The second base 401 is fixed to the top of the bracket 1, and the blocking drive source 402 is fixed to the second base 401, so that the second base 401 is located between the blocking drive source 402 and the track plate 101. That is, the blocking drive source 402 is mounted on the bracket 1 through the second base 401. The blocking block 403 enters or leaves the movement path of the product under test under the drive of the blocking drive source 402. The blocking limiting part physically blocks the product under test by extending into the movement path of the product under test, limiting the product under test within the test area and ensuring that the product under test can be completely tested. As a specific implementation, the blocking drive source 402 can be a cylinder.

[0038] Based on the above solution, this embodiment also provides optional further improvement solutions, please refer to further details. Figure 6 The blocking drive source 402 is located on the top of the bracket 1. The output end of the blocking drive source 402 faces the inside of the bracket 1 and is set diagonally downwards. One end of the blocking block 403 is fixed to the output end of the blocking drive source 402. The inside of the bracket 1 is the side of the bracket 1 closest to the product to be tested. The fact that the output end of the blocking drive source 402 faces the inside of the bracket 1 and is set diagonally downwards helps to reduce the track width and can also block irregularly shaped products to be tested. Furthermore, it can minimize the movement path of the blocking block 403 and improve the efficiency of the blocking process.

[0039] As another optional implementation, the blocking drive source 402 is disposed at the bottom of the bracket 1, and the output end of the blocking output source 402 faces the inside of the bracket 1 and is obliquely upward. As another optional embodiment, the blocking drive source 402 is disposed on the bottom frame, and the output end drives the blocking block to move forward or away from the movement path of the product under test.

[0040] As an alternative implementation, the limiting unit 4 employs a control limiting part (not shown). This control limiting part controls the movement and stopping of the conveying unit 2. The conveying unit 2 stops operating after conveying the product to be tested to the testing area. After the product to be tested is completed, the conveying unit 2 resumes operation. The control limiting part controls the position of the product to be tested by controlling the movement and stopping of the conveying unit 2, thus confining the product to the testing area and ensuring that the product can be completely tested.

[0041] For one specific implementation method, please refer to Figure 2 The pressure plate unit 3 also includes a swing member 304 and a pressure plate fixing member 309. The middle part of the swing member 304 is movably connected to the bracket 1. The end of the swing member 304 away from the bracket 1 is movably connected to the output end of the pressure plate drive source 306. The end of the swing member 304 close to the bracket 1 is fixed to the pressure plate fixing member 309. One end of the pressure plate 310 is fixed to the pressure plate fixing member 309. The other end of the pressure plate 310 extends toward one side of the product to be tested. The pressure plate drive source 306 pushes and pulls the end of the swing member 304 away from the bracket to swing the swing member 304, thereby driving the pressure plate fixing member 309 and the pressure plate 310 to swing, so that the pressure plate 310 can press down on or release the product to be tested; moreover, the pressure plate fixing member 309 is set on the outside of the bracket, that is, one end of the pressure plate 310 is set on the outside of the bracket 1, and the other end of the pressure plate 310 is set on the inside of the bracket 1. The pressure plate 310 spans the bracket 1, and the space in the track width direction is reused with the pressure plate drive source 306, which is conducive to further reducing the track width.

[0042] Based on the above solution, please refer to the following as an optional implementation method: Figure 3The pressure plate unit 3 also includes a limiting part 311, which is disposed between the pressure plate drive source 306 and the swing member 304. The limiting part 311 is a traction member (not shown) located at the end of the swing member 304 away from the bracket 1. The limiting part 311 is used to limit the swing amplitude of the swing member 304. When the output end of the pressure plate drive source 306 moves outward, the traction member provides a traction force that pulls the swing member 304 inward, thereby limiting the swing amplitude of the swing member 304 and thus limiting the lifting height of the pressure plate 310 to avoid damaging the imaging assembly.

[0043] As another alternative implementation, please refer to further details. Figure 6 The pressure plate unit 3 also includes a limiting part 311, which is disposed between the pressure plate drive source 306 and the swing member 304. The limiting part 311 is a support member located at the end of the swing member 304 near the bracket 1, and is used to limit the swing amplitude of the swing member 304. When the output end of the pressure plate drive source 306 moves outward to a certain extent, the support member will press against the swing member 304, thereby limiting the swing amplitude of the swing member 304 and thus limiting the lifting height of the pressure plate 310 to avoid damaging the imaging assembly.

[0044] Based on the above solution, please refer to the following as an optional implementation method: Figure 6 The pressure plate unit 3 also includes a first base 301, which is installed between the bracket 1 and the pressure plate drive source 306. The support member is detachably installed on the outer side of the first base 301. By limiting the swing amplitude of the swing member 304 through the support member, the height of the pressure plate 310 is limited, which makes it easier to bring the light source closer to the product, so that the product receives more uniform illumination and improves the accuracy of the test.

[0045] As another alternative implementation, please refer to further details. Figure 6 The pressure plate unit 3 also includes a first base 301, which is installed between the bracket 1 and the pressure plate drive source 306. A support member extends through the first base 301 along the driving direction of the pressure plate drive source 306 and protrudes from the outer side of the first base 301. The outer side of the first base 301 is the side of the first base 301 facing away from the product to be tested. By limiting the swing amplitude of the swing member 304 through the support member, the height of the pressure plate 310 is limited, which facilitates bringing the distance between the light source and the product closer, making the illumination on the product more uniform, improving the accuracy of the test, and avoiding interference between the pressure plate and the light source when the pressure plate is raised, which is beneficial to maintaining the stability and lifespan of the testing equipment.

[0046] Based on the above scheme, please refer to the following for a specific implementation method. Figure 6The limiting part 311 includes a limiting screw 3111 and a limiting nut 3112. The limiting screw 3111 extends from the inside of the first base 301 to the outside of the pressure plate drive source 306. One end of the limiting screw 3111 protrudes from the outer side of the first base 301 and is located between the outer side of the pressure plate drive source 306 and the swing member 304. The limiting nut 3112 is threadedly connected to the limiting screw 3111 located between the pressure plate drive source 306 and the swing member 304. By turning the limiting nut 3112, the length of the limiting screw 3111 protruding from the outer side of the pressure plate drive source 306 can be adjusted, making the swing amplitude of the swing member 304 adjustable. This allows the height of the pressure plate 310 to be flexibly adjusted, facilitating the adjustment of the distance between the light source and the product according to different products and different light sources, thus achieving the best lighting effect.

[0047] As an alternative embodiment for achieving a movable connection between the middle part of the swing member 304 and the bracket 1, please refer to further details. Figure 2 and Figure 3 The pressure plate unit 3 also includes two connecting plates 302 and two bearings 303. The two connecting plates 302 are located outside the first base 301 and fixed to the outer side of the first base 301. The two connecting plates 302 are arranged in the direction of extension of the bracket 1 and are parallel to each other. The middle part of the swing member 304 is located between the two connecting plates 302. The two connecting plates 302 are provided with bearing holes facing the middle part of the swing member 304 and respectively cooperate with a bearing 303. Two screws are threaded from the outside of the two connecting plates 302 through the two bearings and connected to the middle part of the swing member 304. The outer wall of the screw abuts against the inner wall of the bearing, so that the swing member 304 is movably connected between the two connecting plates 302.

[0048] For one specific implementation method, please refer to further details. Figure 2 and Figure 3 The pressure plate unit 3 also includes a motion connector 307 and a shoulder screw 308. The end of the swing member 304 away from the bracket 1 consists of two swing plates 305. The two swing plates 305 are arranged parallel to each other along the direction of extension of the bracket 1. The swing plates 305 are provided with elongated swing holes 3051. The output end of the pressure plate drive source 306 is set towards the space between the two swing plates 305. One end of the motion connector 307 is connected to the output end of the pressure plate drive source 306, and the other end of the motion connector 307 is located between the two swing plates 305. The shoulder screw 308 is set through the two swing holes 3051 and fixed on the two swing plates 305 by a nut. The shoulder screw 308 is pivotally connected to the motion connector 307.

[0049] As an alternative implementation method, please refer to further information. Figure 1 and Figure 4The support 1 includes a track plate 101 and two fixed seats below the track plate 101. One fixed seat has a receiving space 1031, and the other fixed seat has a track drive source 201 for the conveying unit 2. The receiving space 1031 can accommodate the track drive source 201. By setting the track drive source 201 on one fixed seat and setting the receiving space 1031 on the other fixed seat to cooperate with the track drive source 201, when the track is applied to a dual-track optical inspection device with multiple channels, such as four tracks, the two middle tracks can be set in opposite directions. That is, the fixed seat with the track drive source 201 on one track and the fixed seat with the receiving space 1031 on the other track are located at the same end. Therefore, when the two middle tracks are close to each other, the track drive sources 201 of both tracks can pass through the receiving space 1031 of the other track, so that the distance between the two middle tracks is not limited by the track drive source 201, thus making the distance between the two middle tracks closer. In optical inspection devices of the same size, products with a larger width can be inspected.

[0050] Based on the above scheme, please refer to the following for a specific implementation method. Figure 1 and Figure 4 The support 1 includes a track plate 101, a first fixing seat 102, and a second fixing seat 103. Both the first fixing seat 102 and the second fixing seat 103 are fixed to the bottom of the track plate 101. The first fixing seat 102 and the second fixing seat 103 are respectively located near both ends of the track plate 101. The second fixing seat 103 has a receiving space 1031 for accommodating a track drive source 201 of another track. By placing the track drive source 201 on the first fixing seat 102 and providing the receiving space 1031 on the second fixing seat 103 to cooperate with the track drive source 201, the track can be used in multi-channel dual-track optical inspection equipment, such as four tracks. (See [reference needed]). Figure 5 The two tracks in the middle can be set in opposite directions, that is, the first fixed seat 102 of one track and the second fixed seat 103 of the other track are located at the same end. Therefore, when the two tracks in the middle approach each other, the track drive source 201 of both tracks can pass through the accommodation space 1031 of the other track, so that the distance between the two tracks in the middle is not limited by the track drive source 201, and thus the distance between the two tracks can be closer.

[0051] An alternative implementation method is described in the following document. Figure 1The track for optical inspection equipment includes: a bracket 1, a conveying unit 2, and a pressure plate unit 3. The conveying unit 2 is fixed on the bracket 1 and is used to convey the product to be tested from one end of the bracket 1 to the other end. The pressure plate unit 3 includes a pressure plate drive source 306 and a pressure plate 310. The pressure plate drive source 306 is mounted on the bracket 1 through a first base 301. The output end of the pressure plate drive source 306 faces the outside of the track. The output end of the pressure plate drive source 306 drives the pressure plate to lift or press down through a pressure plate fixing member. The pressure plate is set facing the inside of the track. The pressure plate drive source 306 and the pressure plate achieve spatial reuse in the track width direction, reducing the track width. Furthermore, the track drive source 201 of one track passes through the accommodating space 1031 of another track, further reducing the width of the two adjacent tracks, so that within the same size optical inspection equipment, the track of this embodiment can accommodate a wider product to be tested.

[0052] As an optional implementation, please refer to Figure 1 The conveying unit 2 includes a track drive source 201, a transmission assembly, and a conveying assembly. The track drive source 201 is fixed to the outer side of the support 1, and its output end passes through the support 1. Both the transmission assembly and the conveying assembly are located inside the support 1. The track drive source 201 drives the transmission assembly and is connected to it. The conveying assembly is connected to the transmission assembly and is used to convey the product to be tested. A section of the conveying assembly near the top of the support 1 extends along the direction of the support 1. The track drive source 201 drives the transmission assembly, which in turn drives the conveying assembly to convey the product to be tested.

[0053] Based on the above solution, as an optional implementation method, please refer to... Figure 1The track drive source 201 uses a motor, the transmission assembly uses one driving wheel 202 and four driven wheels 203, and the transmission assembly uses a belt 204. One side of the track drive source 201 with an output shaft is fixed to the outside of the first fixed base 102. The output shaft of the track drive source 201 passes through the first fixed base 102 to its inner side. The driving wheel 202, driven wheels 203, and belt 204 are all located inside the bracket 1. The driving wheel 202 is sleeved and fixed on the output shaft of the track drive source 201, and rotates with the rotation of the output shaft. Two of the four driven wheels 203 are rotatably fixed to the track plate 101 and are respectively located near both ends of the track plate 101. The remaining two driven wheels... 203 is rotatably fixed to the first fixed seat 102 and the second fixed seat 103 respectively. The belt 204 is flexibly connected to the driving wheel 202 and the driven wheel 203. The driving wheel 202 and the two driven wheels 203 located on the track plate 101 are located inside the belt 204. The remaining two driven wheels 203 are located outside the belt 204. The two driven wheels 203 located on the track plate 101 support a section of the belt 204 near the top of the bracket 1, so that the section of the belt 204 near the top of the bracket 1 extends in the direction of the bracket 1. When the driving wheel 202 rotates, the driving wheel 202 drives the belt 204 to move, and the belt 204 drives the driven wheel 203 to rotate, so that the product placed on the belt 204 moves in the direction of the belt 204.

[0054] As an optional implementation, the track drive source 201 can be any of the following: motor, cylinder, electric cylinder, etc.; the transmission component can be one drive wheel 202 and four driven wheels 203; and the transmission component can be a chain.

[0055] As an optional implementation, the track drive source 201 uses a motor, the transmission component uses a sprocket assembly, and the conveying component uses a roller assembly. The choice between a roller assembly and a belt for the conveying component can be determined based on the weight of the product under test.

[0056] On the other hand, embodiments of this application provide an optical inspection device, including a track for an optical inspection device as described above.

[0057] The solutions and components in the above embodiments can be arbitrarily combined and implemented under the same inventive concept, and will not be elaborated on one by one here.

[0058] The embodiments described above are merely examples of several implementation methods of this application, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and this application also intends to include these modifications and variations.
