Description

Technical Field

[0001] This application relates to the field of detection technology, and in particular to a visual inspection device. Background Technology

[0002] With the rapid iteration of electronic products (such as smartphones, tablets, smartwatches, etc.), people are not only pursuing performance but also demanding higher and higher standards for the appearance of electronic products.

[0003] In the production process of mobile phone cover plates and mid-frames, defect detection is an important aspect of quality control. Current detection methods are generally divided into manual inspection and machine vision inspection. Machine vision inspection is gradually replacing manual inspection due to its advantages such as high detection accuracy, saving manpower, and suitability for mass production.

[0004] Currently, in the process of visual inspection of components such as cover plates and middle frames using machines, it is usually necessary to use two inspection modules to inspect the product under test in turn to achieve double-sided inspection of the product under test. This makes the overall structure of the visual inspection equipment complex, large in size, and expensive. Utility Model Content

[0005] This application aims to address at least one of the technical problems existing in the prior art or related technologies.

[0006] In view of this, embodiments of this application provide a visual inspection device.

[0008] The visual inspection equipment provided in this application embodiment, by reasonably setting the positions of the visual inspection module, the feeding module, the translation module, and the two transfer modules, and through the cooperation of the translation module and the two transfer modules, can realize the inspection of the first and second sides of the product under test using only one visual inspection module. Compared with the related technology that uses two inspection modules to inspect the product under test in sequence to achieve double-sided inspection of the product under test, this simplifies the setting of one visual inspection module, simplifies the structure, saves costs, and helps to reduce the overall length, volume, and space occupied by the visual inspection equipment, making it suitable for widespread application.

Detailed Implementation

[0012] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0013] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0014] like Figure 1 , Figure 2 and Figure 3As shown in the embodiment of this application, a visual inspection device is provided, including: a rack module 100; a visual inspection module 200 mounted on the rack module 100; a loading module 300 connected to the rack module 100 and located on one side of the visual inspection module 200, for receiving a product 600 to be tested; two transfer modules 400 and a translation module 500, the transfer modules 400 being connected to the rack module 100 via the translation module 500, the translation module 500 being configured to drive the transfer modules 400 to move along a first direction to approach or move away from the loading module 300 and pass through the visual inspection module 200. The inspection module 200 includes two transfer modules 400, including a first transfer module 401 and a second transfer module 402. The first transfer module 401 is located between the feeding module 300 and the second transfer module 402. The first transfer module 401 is configured to receive the product under test 600 from the feeding module 300 and pass it through the vision inspection module 200 to perform a first-side inspection on the product under test 600. The second transfer module 402 is configured to receive the product under test 600 from the first transfer module 401 and pass it through the vision inspection module 200 to perform a second-side inspection on the product under test 600.

[0015] The product to be tested, 600, can be a mobile phone frame, glass cover, or other similar flat-shaped items. The visual inspection equipment provided in this application embodiment is used to inspect flat-shaped items such as mobile phone frames, mainly to perform defect detection on the first and second sides (such as the front and back) of the item to be tested, in order to meet the quality requirements of high-end manufacturing.

[0016] The visual inspection equipment includes a frame module 100, a visual inspection module 200, a loading module 300, two transfer modules 400, and a translation module 500. The visual inspection module 200, loading module 300, two transfer modules 400, and translation module 500 are all mounted on the frame module 100, providing reliable support for the entire visual inspection equipment and ensuring good inspection accuracy. Specifically, the length direction of the frame module 100 can be understood as the first direction, such as... Figures 1 to 3 As indicated by arrow X, the width direction of rack module 100 can be understood as the second direction, such as... Figures 1 to 3 As indicated by arrow Y, the height direction of rack module 100 can be understood as the third direction, such as... Figures 1 to 3 The arrow Z in the diagram indicates the vertical direction.

[0017] The vision inspection module 200 is mounted on the rack module 100 and is used to perform visual defect detection on the product 600 under test. It is understood that in this embodiment, a vision inspection module 200 is provided to perform detection on the first and second surfaces of the product 600 under test.

[0018] The loading module 300 is connected to the frame module 100 and located on one side of the vision inspection module 200. For example, along the first direction, the loading module 300 is positioned on the right or left side of the frame module 100. The loading module 300 is used to receive the product under test 600. It is understood that the product under test 600 can be transferred to the loading module 300 manually, via an automated production line, or by a robotic arm, enabling the loading module 300 to receive the product under test 600.

[0019] The transfer module 400 is connected to the frame module 100 via a translation module 500. The translation module 500 is configured to drive the transfer module 400 to move along a first direction to approach or move away from the loading module 300 and pass through the vision inspection module 200. Specifically, the transfer module 400 includes a first transfer module 401 and a second transfer module 402. The first transfer module 401 is located between the loading module 300 and the second transfer module 402. That is, along the first direction, the loading module 300, the first transfer module 401, and the second transfer module 402 are arranged sequentially. The first transfer module 401 is configured to receive the product 600 to be tested from the loading module 300 and pass through the vision inspection module 200 for a first-side inspection of the product 600. The second transfer module 402 is configured to receive the product 600 to be tested from the first transfer module 401 and pass through the vision inspection module 200 for a second-side inspection of the product 600. In this way, the translation module 500 drives the first transfer module 401 to move closer to the loading module 300 until it docks with the loading module 300, and transfers the product to be tested 600 on the loading module 300 to the first transfer module 401. Then, the translation module 500 drives the first transfer module 401 past the vision inspection module 200 and stops below the vision inspection module 200, so that the vision inspection module 200 can perform the first surface inspection of the product to be tested 600. After the first side inspection is completed, the translation module 500 drives the first transfer module 401 and / or the second transfer module 402 to move, and docks the first transfer module 401 and the second transfer module 402 at a suitable position. The second transfer module 402 transfers the product to be tested 600 on the first transfer module 401 to the second transfer module 402. Then, the translation module 500 drives the second transfer module 402 to pass through the vision inspection module 200 and stop below the vision inspection module 200, so that the vision inspection module 200 can perform a second side inspection on the product to be tested 600.

[0020] Therefore, by rationally setting the positions of the visual inspection module 200, the feeding module 300, the translation module 500, and the two transfer modules 400, and through the cooperation of the translation module 500 and the two transfer modules 400, the first and second sides of the product under test 600 can be inspected using only one visual inspection module 200. Compared with related technologies that use two inspection modules to inspect the product under test 600 sequentially to achieve double-sided inspection of the product under test 600, this simplifies the setup of one visual inspection module 200, simplifies the structure, saves costs, and helps to reduce the overall length, volume, and space occupied by the visual inspection equipment, making it suitable for widespread application.

[0021] Furthermore, in the embodiments of this application, there are two transfer modules 400, that is, the first transfer module 401 and the second transfer module 402 have the same structure. This can further reduce the complexity of the visual inspection equipment, simplify the structure of the entire equipment, and help improve the standardization and consistency of equipment parts, improve production efficiency, save manufacturing costs, and help save spare parts costs and reduce replacement costs.

[0022] Understandably, after the product under test 600 completes the first-side inspection, the translation module 500 can drive one of the first transfer module 401 and the second transfer module 402 to move, or the translation module 500 can drive both the first transfer module 401 and the second transfer module 402 to move, so that the first transfer module 401 and the second transfer module 402 can dock at a suitable position. Specifically, when the translation module 500 drives both the first transfer module 401 and the second transfer module 402 to move and dock them, one of the first transfer module 401 and the second transfer module 402 can be driven to move to a suitable position first, and then the other can be driven to move so that the two dock at the suitable position.

[0023] In some possible embodiments provided in this application, the translation module 500 is further configured to drive the second transfer module 402 to move away from the loading module 300 to the unloading station. Since the product 600 to be tested on the second transfer module 402 has completed the first and second side inspections after passing through the vision inspection module 200, that is, it has completed double-sided vision inspection, the translation module 500 can drive the second transfer module 402 to the unloading station to facilitate the subsequent transfer of the product 600 to be tested, which has completed double-sided inspection, from the second transfer module 402 to a suitable location for subsequent processes, such as moving the inspection group that has completed the front-side inspection to the inspection equipment to complete the unloading action.

[0024] By setting the discharge station on the side away from the loading module 300, such as setting the discharge station and the loading module 300 on both sides of the frame module 100 along the first direction, the loading, testing and discharge of the product to be tested 600 are arranged sequentially along the first direction, which is a more reasonable layout and helps to improve testing efficiency.

[0025] like Figure 10 , Figure 11 , Figure 12 As shown, in some possible embodiments provided in this application, the feeding module 300 includes a first fixed base 310 and a first flipping table 320. The first flipping table 320 is provided with a plurality of first carriers 330 for receiving the product under test 600. The first fixed base 310 is fixedly connected to the frame module 100, and the first flipping table 320 is flipped and connected to the first fixed base 310.

[0026] In this embodiment, the feeding module 300 is configured as a flipping mechanism. The first flipping table 320 of the feeding module 300 flips relative to the first fixed base 310 to facilitate flipping the first platform 330 to a suitable position, such as flipping the first platform 330 to the feeding station or the transfer station, so as to facilitate feeding and transferring the product to be tested.

[0027] like Figure 13 , Figure 14 , Figure 15 As shown, in some possible embodiments provided in this application, the transfer module 400 includes a second fixed base 410 and a second flipping table 420. The second flipping table 420 is provided with a second platform 430 corresponding to the first platform 330. The second fixed base 410 is connected to the translation module 500, and the second flipping table 420 is flipped and connected to the second fixed base 410.

[0028] In this embodiment, the transfer module 400 is configured as a flipping mechanism. The second flipping table 420 of the transfer module 400 flips relative to the second fixed base 410 to facilitate flipping the second platform 430 to a suitable position, such as flipping the second platform 430 to a docking station or a testing station, so as to facilitate docking, transfer or testing of the product 600 to be tested.

[0029] The feeding module 300 and the transfer module 400 are both set as flipping mechanisms. They have the same working principle and the same design concept, which can further reduce the complexity of the visual inspection equipment, simplify the structure of the entire equipment, and help improve the standardization and consistency of equipment parts, improve production efficiency, save manufacturing costs, and save spare parts costs and reduce replacement costs.

[0030] In some possible embodiments provided in this application, the first flipping table 320 is flipped relative to the first fixed base 310 so that the first platform 330 switches between the loading station and the transfer station. When the loading station is in the loading station, the first platform 330 faces upward, and when the transfer station is in the transfer station, the first platform 330 faces the first transfer module 401, that is, the loading station and the transfer station are 90° apart.

[0031] The second tilting table 420 tilts relative to the second fixed base 410 to allow the second platform 430 to switch between the first docking station, the inspection station, and the second docking station. At the first docking station, the second platform 430 faces the feeding module 300; at the inspection station, the second platform 430 faces upwards; and at the second docking station, the second platform 430 faces away from the feeding module 300. That is, the first docking station and the inspection station are 90° apart, the inspection station and the second docking station are 90° apart, and the first docking station and the second docking station are 180° apart.

[0032] This configuration ensures that the angle between two adjacent workstations of the first stage 330 and the second stage 430 is 90°. The control principle is relatively simple, and the consistent angles facilitate the control of the first and second tilting stages 320 and 420. It also helps to improve the accuracy of the first stage 330 and the second stage 430 when tilting to each workstation, thereby improving the detection accuracy and efficiency.

[0033] In some possible embodiments provided in this application, when the first platform 330 is in the transfer station, that is, the first platform 330 faces the first transfer module 401, and the second platform 430 of the first transfer module 401 is in the first docking station, that is, the second platform 430 faces the loading module 300, at this time, the translation module 500 drives the first transfer module 401 to move so that the second platform 430 docks with the first platform 330. Thus, the transfer of the product under test 600 can be realized, so that the product under test 600 is transferred from the loading module 300 to the first transfer module 401. The operation is convenient and the transfer efficiency is high.

[0034] When the second platform 430 of the first transfer module 401 is in the second docking position, that is, when the second platform 430 of the first transfer module 401 is away from the loading module 300 and facing the second transfer module 402, and the second platform 430 of the second transfer module 402 is in the first docking position facing the loading module 300, that is, facing the first transfer module 401, the translation module 500 drives the first transfer module 401 and / or the second transfer module 402 to dock the two second platforms 430. In this way, the transfer of the product under test 600 can be realized, so that the product under test 600 is transferred from the first transfer module 401 to the second transfer module 402. The operation is convenient and the transfer efficiency is high.

[0035] The first stage 330 and the second stage 430 are both equipped with suction cups. The suction cups can pick up and release the product 600 to be tested. Thus, the transfer of the product 600 to be tested can be achieved by the cooperation of the suction cups on the first stage 330, the second stage 430, and the two second stages 430.

[0036] like Figure 10 , Figure 11 , Figure 12 As shown, in some possible embodiments provided in this application, the feeding module 300 further includes a first rotary table rotatably connected to the first tilting table 320, and a first platform 330 connected to the first rotary table. The first rotary table allows the first platform 330 to rotate 360° relative to the first tilting table 320, thereby facilitating the adjustment of the angle of the first platform 330 relative to the first tilting table 320 to adjust the position and angle of the product 600 to be tested on the first platform 330, thereby improving feeding efficiency and transfer efficiency, and thus improving detection efficiency and detection accuracy.

[0037] like Figure 10 , Figure 11 , Figure 12 As shown, in some possible embodiments provided in this application, the feeding module 300 further includes a first limiting member 350 that is telescopically connected to the first tilting table 320. A plurality of first limiting members 350 are arranged around the periphery of the first platform 330. The relative positions of the first limiting member 350 and the first tilting table 320 include an extended position and a retracted position. The first limiting member 350 in the extended position is configured to limit the rotation of the first platform 330, and the first limiting member 350 in the retracted position is configured to avoid the rotation of the first platform 330.

[0038] In this embodiment, multiple first limiting members 350 are arranged around the periphery of the first platform 330. The first limiting members 350 are configured as telescopic mechanisms relative to the first tilting table 320. The extended positions of the first limiting members 350 limit the rotation of the first platform 330, ensuring that the first platform 330 can reliably and accurately maintain its current position, thereby improving feeding and transfer efficiency, and ultimately improving detection efficiency and accuracy. The retracted positions of the first limiting members 350 prevent the rotation of the first platform 330, allowing the first platform 330 to move flexibly and accurately to a suitable position, thus achieving position adjustment.

[0039] The number of first limiting members 350 can be two, three, four, five, or other numbers, distributed around the perimeter of the first platform 330. The number of first limiting members 350 can be reasonably set according to cost and limiting requirements. Specifically, for example... Figure 10 , Figure 11 , Figure 12As shown, there are 8 first limiting members 350, and the first platform 330 has a rectangular structure with two first limiting members 350 on each side.

[0040] like Figure 10 As shown, in some possible embodiments provided in this application, the first limiting member 350 at the extended position extends to the side of the first platform 330, so that the first limiting member 350 limits the movement of the side of the first platform 330, thereby limiting the rotation of the entire first platform 330, and playing a good limiting role.

[0041] The first limiting member 350 in the retracted position is located below the first platform 330, thereby preventing the first platform 330 from rotating and allowing the first platform 330 to rotate smoothly to the appropriate position.

[0042] Furthermore, the first limiting member 350 in the retracted position is located below the first platform 330 and does not protrude from the top of the first platform 330. In this way, during the transfer of the product under test 600 by docking the first platform 330 with the second platform 430, it will not interfere with the second platform 430, which is conducive to improving the smoothness and reliability of the transfer of the product under test 600.

[0043] In other words, during the transfer of the product to be tested 600, the first limiting member 350 can be in the retracted position. It is understandable that if the first limiting member 350 in the extended position does not protrude from the top of the first stage 330, it will not interfere with the second stage 430, and the first limiting member 350 can also be in the extended position during the transfer of the product to be tested 600.

[0044] Specifically, the first limiting member 350 can be a telescopic column. The telescopic column has a simple structure, reliable limiting, flexible extension and retraction, low cost, and is suitable for application.

[0045] like Figure 11 As shown, in some possible embodiments provided in this application, the feeding module 300 further includes a first flipping limit member 360, which is disposed on the first fixed base 310 and / or the first flipping table 320. The first flipping limit member 360 is configured to limit the flipping angle of the first flipping table 320 relative to the first fixed base 310.

[0046] The first flipping limiter 360 is provided so that the first flipping table 320 can be reliably and accurately flipped to a suitable angle relative to the first fixed seat 310, so that the first carrier 330 is in the loading station or transfer station.

[0047] The first flipping limit member 360 can be set on the first fixed base 310 or the first flipping table 320, or the first limiting flipping member can be set on the first fixed base 310 and the first flipping table 320. The first flipping limit member 360 can be a mechanical stop structure, a stop switch, a collision switch, etc.

[0048] Specifically, the number of first flipping limiting members 360 can be one, to simultaneously limit the flipping of the first flipping table 320 relative to the first fixed table 311 in both clockwise and counterclockwise directions; or, the number of first flipping limiting members 360 can be two, to respectively limit the flipping of the first flipping table 320 relative to the first fixed table 311 in both clockwise and counterclockwise directions. It is understood that the two first flipping limiting members 360 can have the same structure or different structures. Figure 11 An embodiment is shown in which the first flipping limiting member 360 is disposed on the first fixed seat 310. Specifically, the first flipping limiting member 360 can be a mechanical structure, such as the first flipping limiting member 360 can be a first limiting seat, to limit the flipping angle of the first flipping table 320 relative to the first fixed table 311. It can be understood that when the first flipping table 320 flips to abut against the first limiting seat, the first flipping table 320 cannot continue to flip in that direction. At this time, the first carrier 330 is in the transfer position.

[0049] like Figure 10 and Figure 11 As shown, in some possible embodiments provided in this application, the loading module 300 further includes a first tilting drive unit 340, the first fixed base 310 includes a first fixed platform 311 and a first support arm 312, the first fixed platform 311 is connected to the frame module 100, the first support arm 312 is connected to both sides of the first fixed platform 311 along a second direction, the first tilting platform 320 includes a first support platform 321 and a first rotating arm 322, the first rotating arm 322 is connected to both sides of the bottom of the first support platform 321 along a second direction, one first rotating arm 322 is rotatably connected to the first support arm 312 through a first rotating member, and the first tilting drive unit 340 is mounted on the other first support arm 312 and passes through the first support arm 312 to be poweredly connected to the other first rotating arm 322. Thus, when the first tilting drive unit 340 works, it drives the first rotating arm 322 to rotate relative to the first support arm 312, causing the first support platform 321 to tilt relative to the first fixed platform 311, thereby enabling the first platform 330 to tilt to a suitable position. The first rotating component can be a bearing.

[0050] In some possible embodiments provided in this application, the loading module 300 further includes a first rotary drive unit for driving the first rotary tables to rotate. The number of first rotary tables is equal to the number of first carrier stages 330, and each first rotary table can be equipped with a separate first rotary drive unit to drive its rotation. Alternatively, a single first rotary drive unit can be provided, connected to each first rotary table via a first rotary transmission mechanism. This allows one first rotary drive unit to drive each first rotary table to rotate via the first rotary transmission mechanism, simplifying the structure, saving costs, and meeting the design requirements of a compact layout and small size for the loading module 300, thereby reducing the overall size of the vision inspection equipment and saving costs.

[0051] The first rotary transmission mechanism can be a belt drive, chain drive, or other transmission mechanism.

[0052] like Figure 13 , Figure 14 , Figure 15 As shown, in some possible embodiments provided in this application, the transfer module 400 further includes a second rotary table 440 rotatably connected to the second tilting table 420, and a second platform 430 connected to the second rotary table 440. The second rotary table 440 allows the second platform 430 to rotate 360° relative to the second tilting table 420, thereby facilitating the adjustment of the angle of the second platform 430 relative to the second tilting table 420. This allows for adjustment of the position and angle of the product 600 to be tested on the second platform 430, facilitating multi-angle detection of the product 600 and improving detection efficiency and accuracy.

[0053] In some possible embodiments provided in this application, the transfer module 400 further includes a second flipping limiter 470 disposed on the second fixed base 410 and / or the second flipping table 420, the second flipping limiter 470 being configured to limit the flipping angle of the second flipping table 420 relative to the second fixed base 410.

[0054] The second flipping limiter 470 enables the second flipping table 420 to reliably and accurately flip to a suitable angle relative to the second fixed base 410, so that the second platform 430 is in the first docking station, the inspection station, or the second docking station.

[0055] The second flipping limit member 470 can be set on the second fixed base 410 or the second flipping table 420, or the second limit flipping member can be set on the second fixed base 410 and the second flipping table 420. The second flipping limit member 470 can be a mechanical stop structure, a stop switch, a collision switch, etc.

[0056] Specifically, the number of second flipping limiting members 470 can be one, to simultaneously limit the flipping of the second flipping table 420 relative to the second fixed table 411 in both clockwise and counterclockwise directions; or, the number of second flipping limiting members 470 can be two, to respectively limit the flipping of the second flipping table 420 relative to the second fixed table 411 in both clockwise and counterclockwise directions. It is understood that the two second flipping limiting members 470 can have the same structure or different structures. Figure 15 An embodiment is shown in which the second flipping limiting member 470 is disposed on the second fixed seat 410. Specifically, the second flipping limiting member 470 can be a mechanical structure, such as the second limiting seat, to limit the flipping angle of the second flipping table 420 relative to the second fixed table 411. It can be understood that when the second flipping table 420 flips to abut against the second limiting seat, the second flipping table 420 cannot continue to flip in that direction. At this time, the second platform 430 is in the first docking position or the second docking position.

[0057] like Figure 13 and Figure 14 As shown, in some possible embodiments provided in this application, the transfer module 400 further includes a second flipping drive unit 450. The second fixed base 410 includes a second fixed platform 411 and a second support arm 412. The second fixed platform 411 is connected to the frame module 100. The second support arm 412 is connected to both sides of the second fixed platform 411 along a second direction. The second flipping platform 420 includes a second support platform 421 and a second rotating arm 422. The second rotating arm 422 is connected to both sides of the bottom of the second support platform 421 along a second direction. One second rotating arm 422 is rotatably connected to the second support arm 412 through a second rotating member. The second flipping drive unit 450 is mounted on the other second support arm 412 and passes through the second support arm 412 to be poweredly connected to the other second rotating arm 422. Thus, when the second flipping drive unit 450 operates, it drives the second rotating arm 422 to rotate relative to the second support arm 412, causing the second support platform 421 to flip relative to the second fixed platform 411, thereby enabling the second platform 430 to flip to a suitable position. The second rotating component can be a bearing.

[0058] like Figure 13 As shown, in some possible embodiments provided in this application, the transfer module 400 further includes a second rotary drive unit 460, which drives the second rotary table 440 to rotate. The number of second rotary tables 440 is equal to the number of second platforms 430, and a separate second rotary drive unit 460 can be provided for each second rotary table 440 to drive its rotation. Alternatively, as... Figure 13 and Figure 14As shown, a second rotary drive unit 460 can be set up, and the second rotary drive unit 460 and each second rotary table 440 can be connected through a second rotary transmission mechanism. This allows the second rotary drive unit 460 to drive each second rotary table 440 to rotate through the second rotary transmission mechanism, thereby simplifying the structure, saving costs, and meeting the design requirements of the transfer module 400 for a compact layout and small size. This reduces the overall size of the vision inspection equipment and saves costs.

[0059] The second rotary transmission mechanism can be a belt drive, chain drive, or other transmission mechanism.

[0060] like Figure 16 and Figure 17 As shown, in some possible embodiments provided in this application, the translation module 500 includes: two first linear modules 510, which are disposed on the frame module 100 and connected to the first transfer module 401 and the second transfer module 402 respectively, so as to drive the first transfer module 401 and the second transfer module 402 to move along the first direction respectively.

[0061] This embodiment discloses the specific structure of the translation module 500. The translation module 500 includes two first linear modules 510, which respectively drive the first transfer module 401 and the second transfer module 402 to move along a first direction, enabling the two first transfer modules 401 to move accurately and quickly to a suitable position, thereby improving transfer efficiency and detection efficiency.

[0062] Specifically, by using two first linear modules 510 to drive the first transfer module 401 and the second transfer module 402 to move along the first direction, the movement of the first transfer module 401 and the second transfer module 402 can be controlled by the individual first linear modules 510, thereby improving the speed and accuracy of the movement of the first transfer module 401 and the second transfer module 402 and reducing the possibility of mutual interference during their movement.

[0063] In some possible embodiments provided in this application, the two first linear modules 510 are configured with the same structure. This further reduces the complexity of the visual inspection equipment, simplifies the overall structure, and facilitates the standardization and consistency of equipment components, thereby increasing production efficiency, saving manufacturing costs, and reducing spare parts costs and replacement costs. Specifically, the two first linear modules 510 are first linear module a501 and first linear module b502, respectively. First linear module a501 is connected to the first transfer module 401, and first linear module b502 is connected to the second transfer module 402.

[0064] Among them, such as Figure 16 and Figure 17As shown, the first linear module 510 includes: a first translation drive unit 511, a first lead screw 512, and a first slide. One end of the first lead screw 512 is poweredly connected to the first translation drive unit 511, and the other end passes through the first slide and is threadedly connected to the first slide. The first slide is configured to be connected to the first transfer module 401 or the second transfer module 402.

[0065] In other words, the first linear module 510 is a lead screw slide translation mechanism. The lead screw slide translation mechanism has a simple structure, good stability, high precision, strong structural rigidity, and high reliability.

[0066] like Figure 17 As shown, in some possible embodiments provided in this application, the first lead screws 512 of the two first linear modules 510 are arranged in parallel and opposite directions.

[0067] Since both transfer modules 400 reciprocate along the first direction, by setting the first lead screws 512 of the two first linear modules 510 parallel along the first direction, the motion accuracy of the first transfer module 401 and the second transfer module 402 can be ensured, enabling them to quickly and accurately dock and improve their transfer accuracy.

[0068] By arranging the first lead screws 512 of the two first linear modules 510 opposite to each other, the space occupied by the two first lead screws 512 in the first direction can be reduced, thereby reducing the length of the vision inspection device in the first direction and reducing the volume of the vision inspection device.

[0069] In the above embodiment, the lengths of the first lead screws 512 of the two linear modules are equal. Therefore, while ensuring that the first transfer module 401 and the second transfer module 402 have sufficient travel, the space occupied by the two first lead screws 512 in the first direction is further reduced, thus reducing the length of the vision inspection device in the first direction and the volume of the vision inspection device.

[0070] like Figure 17 As shown, in some possible embodiments provided in this application, a second limiting member 513 is provided on the first lead screw 512 to limit the movement of the first slide. The setting of the second limiting member 513 enables the first slide to drive the first transfer module 401 and the second transfer module 402 to a suitable position, reducing or avoiding the possibility that the first transfer module 401 or the second transfer module 402 may exceed the limit position and continue to move, causing damage to other components, which is beneficial to improving the overall reliability of the equipment.

[0071] Two second limiting members 513 are spaced apart on the same first lead screw 512 to limit the forward or reverse movement of the first slide. For example, the two second limiting members 513 on the first linear module 510 connected to the first transfer module 401 limit the first slide, so that the first transfer module 401 stops at the position docked with the loading module 300, the position docked with the second transfer module 402, or directly below the vision inspection module 200. The two second limiting members 513 on the second linear module 241 connected to the second transfer module 402 limit the first slide, so that the second transfer module 402 stops at the unloading station, the position docked with the first transfer module 401, or directly below the vision inspection module 200.

[0072] The second limiting element 513 can be a limiting seat, a limiting block or other limiting mechanism, and this application does not make specific limitations.

[0073] like Figure 16 and Figure 17 As shown, in some possible embodiments provided in this application, the first linear module 510 further includes a first transmission mechanism 514. The first transmission mechanism 514 includes a driving wheel 515, a driven wheel 516, and a transmission belt 517 wound around the driving wheel 515 and the driven wheel 516. The driving wheel 515 is poweredly connected to the first translation drive unit 511, and the driven wheel 516 is poweredly connected to the first lead screw 512.

[0074] In this embodiment, the power of the first translation drive unit 511 is transmitted to the first lead screw 512 through the first transmission mechanism 514, thereby enabling the first translation drive unit 511 to work and drive the first lead screw 512 to rotate. Since the first transmission mechanism 514 is a belt drive mechanism, it can change the direction of the power of the first translation drive unit 511 and transmit it to the first lead screw 512. That is, the first transmission mechanism of belt drive can arrange the first translation drive unit 511 and the first lead screw 512 in parallel. Therefore, compared with the related technology where the first translation drive unit 511 directly drives the first lead screw 512 to rotate, which requires the first translation drive unit 511 and the first lead screw 512 to be arranged coaxially, the size of the first linear module 510 along the first direction can be reduced, thereby reducing the size of the translation module 500 along the first direction. This is beneficial to reducing the size of the vision inspection device along the first direction, reducing the volume of the vision inspection device, and meeting the design requirements of compact structure and small size of the vision inspection device.

[0075] like Figure 17As shown, in some possible embodiments provided in this application, the first translation drive units 511 of the two first linear modules 510 are arranged opposite to each other along a first direction. That is, the first translation drive unit 511 of one first linear module 510 is disposed on the left side of the entire translation module 500 along the first direction, and the first translation drive unit 511 of the other first linear module 510 is disposed on the right side of the entire translation module 500 along the first direction. Thus, the two first translation drive units 511 can be reasonably distributed on the left and right sides of the translation module 500. Compared with the two first translation drive units 511 being arranged side by side on one side of the translation module 500, which would increase the size of the translation module 500 along the second direction, arranging the first translation drive units 511 of the two first linear modules 510 opposite to each other along the first direction can minimize the size of the translation module 500 along the second direction, thereby helping to reduce the size of the entire visual inspection device in the second direction and meeting the design requirements of compact structure and small size of the visual inspection device.

[0076] like Figure 17 As shown, in some possible embodiments provided in this application, the first translation drive unit 511 is located between the two first lead screws 512, so that the two first translation drive units 511 can be arranged opposite to each other. This allows the first translation drive unit 511 to make reasonable use of the space between the two first lead screws 512. Compared with the first translation drive unit 511 being located on one side of the two first lead screws 512, the size of the translation module 500 along the second direction is further reduced. At the same time, this arrangement results in a high overlap rate of the space occupied by the two first translation drive units 511, which helps to reduce the size of the entire vision inspection device in the second direction, meeting the design requirements of a compact structure and small size for the vision inspection device.

[0077] like Figure 16 and Figure 17 As shown, in some possible embodiments provided in this application, the translation module 500 further includes: a support base 520, the bottom of which is connected to the frame module 100; two first linear modules 510 are disposed inside the support base 520; the top of the support base 520 is provided with an opening 521; the first slide is connected to the transfer module 400 through the opening 521; and the loading module 300 spans the support base 520 and is connected to the frame module 100 or to the support base 520.

[0078] In this embodiment, the support base 520 provides good protection for the first linear module 510, reducing or preventing damage from external objects or dust contamination, thus extending its service life and improving its reliability. The top opening 521 of the first linear module 510 ensures smooth connection between its first slide and the transfer module 400, allowing the transfer module 400 to move along the lead screw in the first direction. Specifically, the first slide can be connected to the second fixed base 410 of the transfer module 400.

[0079] The feeding module 300 can be connected to the frame module 100 across the support base 520, or the feeding module 300 can be directly connected to the support base 520.

[0080] like Figure 16 As shown, in some possible embodiments provided in this application, first guide rails are provided on both sides of the bottom of the transfer module 400, and a first slide rail 522 is provided on the edge of the opening 521 of the support base 520. The first guide rails are configured to move along the first slide rail 522. Thus, by moving the first guide rails along the first slide rail 522, the movement of the transfer module 400 relative to the support base 520 is guided and limited, thereby guiding and limiting the movement of the transfer module 400 relative to the frame module 100, which helps to improve the movement accuracy of the transfer module 400, and improves the transfer accuracy and detection accuracy. Specifically, the first guide rails can be provided at the bottom of the second fixed platform 411 of the transfer module 400.

[0081] like Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, in some possible embodiments provided in this application, the visual inspection module 200 includes: a bracket 210, a support frame 220, a detection component 230, and a power mechanism. The bracket 210 is arranged along a second direction on opposite sides of the top of the frame module 100. The detection component 230 is mounted on the support frame 220 and located above the frame module 100. The power mechanism connects the bracket 210 and the support frame 220. The power mechanism is configured to drive the support frame 220 to move relative to the bracket 210 along the second direction and in the vertical direction. The second direction is perpendicular to the first direction, and the number of detection components 230 is equal to the number of first platforms 330.

[0082] This embodiment provides the specific structure of the visual inspection module 200. The visual inspection module 200 is mounted on the rack module 100 via brackets 210. Two brackets 210 are arranged on both sides of the rack module 100 along a second direction, perpendicular to the first direction. The detection component 230 is mounted on a support frame 220, which is connected to the brackets 210 via a motion mechanism 240. The motion mechanism 240 moves the support frame 220 relative to the brackets 210 along the second direction and vertically, adjusting the position of the detection component 230 to improve detection accuracy.

[0083] The number of detection components 230 is equal to the number of the first stage 330, and the number of the second stage 430 is equal to the number of the first stage 330. This means that the detection components 230 correspond one-to-one with the first stage 330 and the second stage 430. Therefore, the products 600 to be tested on the first stage 330 and the second stage 430 can be inspected in a targeted manner. This allows the vision inspection module 200 to inspect all products 600 on the first stage 330 and all products 600 on the second stage 430 at once, improving inspection efficiency and meeting the mass production needs of the products 600. Specifically, as shown... Figure 1 As shown, there are four stages: the first stage 330, the second stage 430, and the detection component 230. Therefore, using the visual inspection device, four products 600 to be inspected can be visually inspected simultaneously. It is understood that in other examples, the number of stages 330, 430, and the detection component 230 may also be other than those shown.

[0084] like Figure 6 As shown, in some possible embodiments provided in this application, the motion mechanism 240 includes two second linear modules 241, which are configured with the same structure. This can further reduce the complexity of the vision inspection device, simplify the structure of the entire device, improve the standardization and consistency of the device parts, increase production efficiency, save manufacturing costs, and save spare parts costs and reduce replacement costs.

[0085] Among them, such as Figure 6 As shown, the second linear module 241 includes: a second translation drive unit 245, a second lead screw 246, and a second slide. One end of the second lead screw 246 is poweredly connected to the second translation drive unit 245, and the other end passes through the second slide and is threadedly connected to the second slide. The second lead screws 246 of the two second linear modules 241 are arranged vertically. The second translation drive unit 245 of one second linear module 241 is mounted on the bracket 210, and the second slide is connected to the intermediate plate 244. The second translation drive unit 245 of the other second linear module 241 is mounted on the intermediate plate 244, and the second slide is configured to be connected to the support frame 220.

[0086] Specifically, the two second linear modules 241 are second linear module a242 and second linear module b243, respectively. The second slide of second linear module a242 is connected to the intermediate plate 244, and the second slide of second linear module b243 is connected to the support frame 220. Thus, movement of the second slide of second linear module a242 can cause the intermediate plate 244 to move relative to the bracket 210 along a second direction, thereby causing the detection component 230 on the support frame 220 to move along the second direction. Movement of the second slide of second linear module b243 can cause the support frame 220 to move relative to the intermediate plate 244 along a third direction, wherein the third direction is vertical, thereby causing the detection component 230 on the support to move along the vertical direction.

[0087] Among them, the second linear module 241 is a lead screw slide translation mechanism. The lead screw slide translation mechanism has good structural testing, good stability, high precision, strong structural rigidity, and high reliability.

[0088] In this embodiment, the detection component 230 can be moved in the second direction and the vertical direction by the second linear module 241 of two identical and vertically arranged lead screw slide mechanisms. The structure is simple and the motion accuracy is high, which is beneficial to improving the detection accuracy.

[0089] Furthermore, for the intermediate plate 244 moving relative to the bracket 210 in the second direction, and the support frame 220 moving relative to the intermediate plate 244 in the vertical direction, guide rails can be provided for guidance to improve motion accuracy. Limiting structures can also be provided to limit the extreme positions of the movement, allowing the detection component 230 to move within a suitable range, reducing or avoiding the possibility of the detection component 230 moving outside the suitable range and colliding with other components, thus improving the overall reliability of the equipment.

[0090] like Figure 6 As shown, in some possible embodiments provided in this application, the detection component 230 includes a mounting frame 231, and a camera component 232 and a light source component arranged sequentially downward along the vertical direction on the mounting frame 231. The light source component includes an annular light source 233 and a plurality of line light sources 234 distributed around the annular light source 233.

[0091] In this embodiment, the detection component 230, composed of a line light source 234, a ring light source 233, and a camera component 232, has good detection accuracy and high detection efficiency compared with manual detection. Compared with laser scanning fusion detection technology, it has lower requirements for computing power and lower hardware costs, making it suitable for widespread application.

[0092] The ring light source 233, by illuminating the object from all sides, provides a uniform light distribution, reduces shadow interference, and is particularly suitable for the inspection of highly reflective material surfaces. It reduces light loss, improves imaging clarity, and uniformly illuminates the object surface, thereby improving inspection accuracy. Specifically, the ring light source 233 can effectively detect weak defects, further enhancing inspection accuracy.

[0093] Among them, the line light source 234 forms high-brightness and high-uniformity light through an optical lens system, which can accurately illuminate the details of the object surface. Especially in high-speed assembly line scenarios, it can instantly capture tiny defects of fast-moving objects such as thin films and electronic components, which is beneficial to improving detection accuracy.

[0094] The number of line light sources 234 can be two, three, four, or more, to further increase the radiation range and improve detection accuracy. Specifically, the number of line light sources 234 in this application can be three.

[0095] The light emission angle of the line light source 234 is adjustable, which can be adjusted according to the specific position of the product under test 600, thereby improving detection efficiency and detection accuracy.

[0096] like Figure 7 As shown, in some possible embodiments provided in this application, a fixing frame 2331 is provided around the annular light source 233, and a pair of adjusting plates 2332 are provided around the fixing frame 2331. An arc-shaped sliding groove 2333 is provided on the adjusting plate 2332. The line light source 234 includes a fixing plate 2341, and the two ends of the fixing plate 2341 are located in the arc-shaped sliding groove 2333 of the pair of fixing frames 2331 and can move along the arc-shaped sliding groove 2333.

[0097] In this embodiment, the line light source 234 is mounted on the fixing frame 2331 of the annular light source 233 by the fixing plate 2341. The light emission angle of the line light source 234 can be adjusted by the movement of the fixing plate 2341 within the arc-shaped sliding groove 2333 of the fixing frame 2331. The structure is simple and easy to implement.

[0098] like Figure 4 and Figure 5 As shown, in some possible embodiments provided in this application, the rack module 100 includes a rack assembly 110 and an electrical control box 120. The vision inspection module 200, the loading module 300, the transfer module 400, and the translation module 500 are disposed on the top of the rack assembly 110. The electrical control box 120 is disposed inside the rack assembly 110 and is communicatively connected to the vision inspection module 200, the loading module 300, the transfer module 400, and the translation module 500.

[0099] The frame assembly 110 provides excellent support for the vision inspection module 200, the loading module 300, the transfer module 400, and the translation module 500, which helps improve the stability of the vision inspection equipment and thus improves the inspection accuracy. At the same time, the frame assembly 110 provides good protection for the electrical control box 120, which helps extend the service life of the electrical control box 120.

[0100] The electrical control box 120 is connected to the vision inspection module 200, the feeding module 300, the transfer module 400, and the translation module 500 to control the vision inspection module 200, the feeding module 300, the transfer module 400, and the translation module 500, thereby realizing the visual defect detection of the product 600 to be tested.

[0101] Furthermore, the rack assembly 110 has an internal mounting cavity, which can be used to install the electrical control box 120, as well as other electronic components or other parts, which will not be listed here.

[0102] like Figure 4 and Figure 5 As shown, in some possible embodiments provided in this application, the rack module 100 further includes a roller module 130, which is disposed at the bottom of the rack assembly 110. The roller module 130 allows the rack assembly 110 to be moved to a suitable position by rotation, thereby moving the entire vision inspection equipment to the appropriate position. This simplifies the user's operation of moving the vision inspection equipment, saves manpower, is convenient to operate, and facilitates the movement of the vision inspection equipment.

[0103] Specifically, there are four roller modules 130, which are distributed at the four corners of the frame assembly 110.

[0104] like Figure 4 and Figure 5 As shown, in some possible embodiments provided in this application, the rack module 100 further includes a support foot 140 movably connected to the bottom of the rack assembly 110. The relative positions of the support foot 140 and the rack assembly 110 include a supporting position and a retracted position. When the support foot 140 is in the supporting position, its bottom end is located below the bottom end of the roller module 130, and when the support foot 140 is in the retracted position, its bottom end is located above the roller module 130.

[0105] In this embodiment, by providing a movable support foot 140 at the bottom of the frame assembly 110, when the support foot 140 is in the support position relative to the frame assembly 110, the bottom end of the support foot 140 is located below the bottom end of the roller module 130, so that the support foot 140 suspends the roller module 130. In this way, the visual inspection equipment is reliably and stably supported in a suitable position by the support frame 220, reducing the possibility of movement or shaking of the visual inspection equipment. At this time, visual inspection of the product 600 under test can be performed, which is beneficial to improving the inspection accuracy.

[0106] When the support leg 140 is in the retracted position relative to the frame assembly 110, the bottom end of the support leg 140 is above the roller module 130, so that the roller module 130 suspends the support leg 140. In this way, the visual inspection equipment can be moved to a suitable position using the roller module 130, which facilitates the movement and operation of the visual inspection equipment.

[0107] Therefore, by using the roller module 130 and the movable support foot 140 together, the visual defect equipment can be moved easily, and the visual inspection equipment can be reliably and stably supported in a suitable position to ensure good inspection accuracy.

[0108] The number of support feet 140 is the same as the number of roller modules 130, that is, four support feet 140 are movably set at the bottom of the frame assembly 110 to improve the reliability and stability of the support feet 140 in supporting the vision inspection equipment.

[0109] like Figure 5 As shown, in some possible embodiments provided in this application, the support foot 140 is connected to the frame assembly 110 by a threaded structure, such as the support frame 220 being a threaded support column. Thus, by screwing the support foot 140, the support foot 140 can be switched between a supporting position and a retracted position.

[0110] Understandably, the rack module 100 also includes a locking element 150 to lock and secure the support foot 140 after it has been adjusted to a suitable position relative to the rack assembly 110, ensuring that the support foot 140 can be reliably and stably maintained in its current position. Specifically, the locking element 150 may be a lock nut.

[0111] Specifically, such as Figures 1 to 17 As shown, taking the loading module 300 arranged along the first direction on the left side of the frame module 100 as an example, the working principle of the improved vision inspection module 200 of this application will be explained: First, the first tilting table 320 of the loading module 300 tilts relative to the first fixed table 311, positioning the first platform 330 in the loading position, i.e., with the first platform 330 facing upwards, so that the product to be tested 600 can be placed on the first platform 330. It is understood that the product to be tested 600 can be placed on the first platform 330 manually or by a robotic arm. In some examples, the first platform 330 is initially in the loading position, which simplifies the tilting operation of the first tilting table 320.

[0112] Understandably, after the first platform 330 is in the loading station but before the product to be tested 600 is placed on it, the first rotary table can be used to adjust the position of the first platform 330 so that it is in a suitable position, allowing the product to be tested 600 to be placed on it in a proper posture. Simultaneously, the first limiting member 350 can be in the extended position to limit the rotation of the first platform 330, reducing the possibility of it shaking or rotating during loading. Then, the loading operation can proceed.

[0113] After the loading is completed, i.e., after the product to be tested 600 is placed on the first platform 330, the first limiting member 350 can be retracted to avoid interfering with the transfer operation. Then, the first tilting table 320 of the loading module 300 is tilted relative to the first fixed base 310 (e.g., rotated 90° clockwise), so that the first platform 330 is in the transfer station, i.e., the first platform 330 faces the first transfer module 401 and is facing right. The second tilting table 420 of the first transfer module 401 is tilted relative to the second fixed base 410 (e.g., rotated 90° counterclockwise), so that the second platform 430 is in the first docking station, i.e., the second platform 430 faces the loading module 300 and is facing left. The first linear module a501 of the translation module 500 drives the first transfer module 401 to move closer to the loading module 300 (e.g., to the left), until the second platform 430 and the first platform 330 are docked. The suction cups on the second platform 430 work to pick up the product 600 to be tested, and the suction cups on the first platform 330 stop working to release the product 600 to be tested, transferring the product 600 to be tested onto the second platform 430 of the first transfer module 401. Then, the second flipping platform 420 of the first transfer module 401 flips relative to the second fixed platform 411 (e.g., rotates 90° clockwise), so that the second platform 430 is in the testing position, that is, the second platform 430 is facing upwards. Next, the first linear module a501 of the translation module 500 drives the first transfer module 401 to move away from the feeding module 300, such as to the right, so that the first transfer module 401 moves directly below the vision inspection module 200, so that the vision inspection module 200 can perform visual defect detection on the first surface of the product 600 to be tested.

[0114] Before performing the first-side visual inspection of the product 600 under test using the visual inspection module 200, the position of the detection component 230 can be adjusted along the second direction using the second linear module a242 on the visual inspection module 200, and the position of the detection module can be adjusted along the third direction using the second linear module b243, so that the detection component 230 is opposite to the second stage 430, thereby improving the detection accuracy.

[0115] In the process of performing the first-side visual inspection of the product 600 under test using the visual inspection module 200, the second rotary table 440 of the first transfer module 401 can be controlled to rotate, so that the second platform 430 can rotate 360°. The posture of the product under test can be freely adjusted according to the requirements to achieve full-view inspection without blind spots, thereby improving the inspection accuracy and increasing the shipment qualification rate.

[0116] After the loading module 300 and the first transfer module 401 complete the docking of the product to be tested 600, the first flipping table 320 of the loading module 300 flips relative to the first fixed seat 310 (such as flipping 90° counterclockwise), so that the first platform 330 is in the loading position, that is, the first platform 330 faces upward, restoring the initial position, so as to facilitate subsequent loading operations here.

[0117] After completing the first visual inspection of the product 600, the second tilting table 420 of the first transfer module 401 is tilted relative to the second fixed table 411 (e.g., rotated 90° clockwise), so that the second platform 430 is in the second docking position, that is, the second platform 430 is away from the loading module 300 and faces to the right. At the same time, the first linear module a501 controls the first transfer module 401 to move closer to the loading module 300, such as moving to the left, to free up the space below the visual inspection module 200. The second tilting platform 420 of the second transfer module 402 tilts relative to the second fixed platform 411 (e.g., rotates 90° counterclockwise), placing the second platform 430 in the first docking position, i.e., the second platform 430 faces the loading module 300. The first linear module b502 controls the second transfer module 402 to move closer to the loading module 300, such as moving to the left, so that the two second platforms 430 dock. The suction cups on the second platform 430 of the second transfer module 402 work to adsorb the product 600 to be tested. The suction cups on the second platform 430 of the first transfer module 401 stop working and release the product 600 to be tested, transferring the product 600 to be tested onto the second platform 430 of the second transfer module 402. Then, the second tilting platform 420 of the second transfer module 402 tilts relative to the second fixed platform 411 (e.g., rotates 90° clockwise), placing the second platform 430 in the detection position, i.e., the second platform 430 faces upward. Next, the first linear module b502 of the translation module 500 drives the second transfer module 402 to move away from the feeding module 300, such as to the right, so that the second transfer module 402 moves directly below the vision inspection module 200, so that the vision inspection module 200 can perform visual defect detection on the second side of the product 600 to be tested.

[0118] Before performing a second-side visual inspection on the product 600 under test using the visual inspection module 200, the position of the detection component 230 can be adjusted along the second direction using the second linear module a242 on the visual inspection module 200, and the position of the detection module can be adjusted along the vertical direction using the second linear module b243, so that the detection component 230 is opposite to the second stage 430, thereby improving the detection accuracy.

[0119] In the process of performing a second-side visual inspection of the product 600 under test using the visual inspection module 200, the second rotary table 440 of the second transfer module 402 can be controlled to rotate, so that the second stage 430 can rotate 360°. The posture of the product under test can be freely adjusted according to the requirements to achieve full-view inspection without blind spots, thereby improving the inspection accuracy and increasing the shipment qualification rate.

[0120] After the second transfer module 402 and the first transfer module 401 complete the docking of the product to be tested 600, the second flipping table 420 of the first transfer module 401 flips relative to the second fixed base 410 (such as flipping 90° counterclockwise), so that the second platform 430 is in the testing position, that is, the second platform 430 faces upward, and the initial position is restored.

[0121] After completing the second-side visual inspection of the product under test 600, the first linear module b502 controls the second transfer module 402 to move away from the loading module 300 (e.g., to the right) to the unloading station, so as to facilitate the unloading operation of the product under test 600 that has completed double-sided visual inspection. It is understood that the unloading operation of the product under test 600 can be performed manually or by a robotic arm.

[0122] The visual inspection equipment provided in this embodiment can simultaneously inspect multiple products 600 to be tested. The second rotary table 440 drives the second platform 430 to rotate, which in turn rotates the products 600 to be tested. During inspection, the posture of the products 600 can be freely adjusted as needed to achieve full-view, blind-spot-free inspection, thereby improving the inspection accuracy and increasing the pass rate. By rationally setting the positions of the visual inspection module 200, the feeding module 300, the first transfer module 401, the second transfer module 402, and the translation module 500, and through the cooperation of the translation module 500 and the two transfer modules 400, the first and second sides of the product 600 can be inspected using only one visual inspection module 200. This simplifies the structure, saves costs, and helps reduce the overall length of the visual inspection equipment. The length L of the entire visual inspection equipment can be controlled within an 800mm space range to integrate the various modules, greatly reducing the space occupancy rate of the visual inspection equipment.

[0123] Furthermore, by rationally setting the positions of the vision inspection module 200, the feeding module 300, the first transfer module 401, the second transfer module 402, and the translation module 500, the width of the entire vision inspection equipment can be compressed, so that the width W of the vision inspection equipment can be controlled within a space range of 1100mm to achieve the integration of each module, which greatly reduces the space occupancy rate of the vision inspection equipment.

[0124] Furthermore, the height H of the visual inspection equipment can be controlled within a space range of 2190mm to achieve the integration of various modules, which greatly reduces the space occupancy rate of the visual inspection equipment.

[0125] The length L, width W, and height H of the visual inspection equipment can be as follows: Figures 1 to 3 As shown.

[0126] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
