Abstract

This invention relates to the field of metal connector technology, specifically disclosing a metal connector production quality inspection device, including a first base and a second base. A platform is fixedly connected to one side of the interior of the first base. Through the coordinated operation of the air blowing mechanism and the wiping mechanism, the automatic cleaning of the camera lens and the glass plate surface is realized simultaneously. During the cleaning process, the high-pressure gas generated by the air pump is diverted through the straight air pipe and the three-way pipe, and then accurately sprayed from the first air blowing head and the second air blowing head onto the camera lens and the glass plate surface, quickly blowing away the attached metal debris and dust. At the same time, the soft brush of the wiping mechanism reciprocates under the drive of the power component, gently wiping away the stubborn debris remaining after air blowing.

Description

Technical Field

[0001] This invention relates to the field of metal connector technology, and in particular to a metal connector production quality inspection device. Background Technology

[0002] Metal connectors are metal components that are fixed or driven by welding, bolting, or other methods. They are widely used in machinery, automotive, and aerospace industries. Their structural integrity and dimensional accuracy directly affect the overall stability of equipment. Because defects such as cracks, deformation, and dimensional deviations are prone to occur during production, quality inspection equipment is needed to control quality. Industrial vision cameras, with their high-speed imaging and accurate recognition capabilities, can quickly capture the surface and dimensional details of metal connectors, enabling automated defect detection. Compared with manual inspection, this method is more efficient and has smaller errors, effectively preventing unqualified products from entering the market and ensuring production quality and safety in use.

[0003] For example, Chinese patent CN214224965U discloses a metal surface inspection device, including: two support columns, which are opposite each other on both sides of a metal strip conveyor line, and a rotating mechanism is rotatably mounted on the support columns; an inspection module, including an inspection camera and a camera protective cover, the camera protective cover being mounted on the rotating mechanism, and several inspection cameras being arranged in the camera protective cover along the width of the metal strip to photograph the surface of the metal strip; and an inspection light source, mounted on the rotating mechanism, which illuminates the surface of the metal strip for light compensation; the rotating mechanism, the inspection module, and the inspection light source are provided above and below the metal strip.

[0004] Currently, existing metal connector quality inspection devices have several shortcomings that urgently need improvement: First, after the metal connectors fall onto the inspection table, they are prone to shifting or tilting due to the lack of an effective positioning structure. This results in deviations in the images captured by the industrial vision camera, making it impossible to accurately capture surface defects and dimensional information of the parts, directly affecting the accuracy and reliability of the inspection results. Second, the inspection process lacks continuity, requiring manual assistance in steps such as parts loading, leading to low inspection efficiency and difficulty in meeting the needs of mass production. Third, during the inspection process, debris from the surface of the metal connectors easily falls and adheres to the camera lens and the inspection table surface. Existing devices are not equipped with automatic cleaning mechanisms, requiring regular manual cleaning. This is not only cumbersome and time-consuming to maintain, but also prone to causing lens blurring and a decrease in the accuracy of the inspection table's reference surface if cleaning is not timely, further affecting the inspection quality of subsequent parts.

[0015] Compared with the prior art, the beneficial effects of the present invention are: Firstly, in this invention, after the metal connector conveyed from the unloading track falls onto the glass tray, the first guide wheel guides the workpiece towards the inside of the glass tray, while the second guide wheel simultaneously guides the workpiece towards the outside of the glass tray. Through the coordinated limiting of the two guide wheels, the metal connector is accurately positioned in the detection area of ​​the glass tray, avoiding offset or tilting. When the metal connector passes under the infrared optical fiber as the glass tray rotates, the infrared optical fiber monitors the position of the workpiece in real time to ensure that the part is placed in a reasonable position. After a delay of a few seconds, the camera is triggered to take a picture. The height of the infrared optical fiber can be flexibly adjusted by the first adjustment component so that the optical fiber is just blocked by the workpiece, realizing automatic image positioning and normal picture taking. If the optical fiber is too high, it will not be able to sense the workpiece, resulting in missed pictures. If the height is too low, it will mistakenly sense the glass tray, resulting in multiple pictures, effectively ensuring the accuracy of the detection process. At the same time, the second adjustment component can adjust the horizontal position of the first and second guide wheels respectively, flexibly adapting the spacing according to the metal connector of different sizes, greatly improving the applicability of the equipment.

[0016] Secondly, in this invention, the automatic cleaning of the camera lens and the glass plate surface is achieved simultaneously through the coordinated operation of the blowing mechanism and the wiping mechanism. During the cleaning process, the high-pressure gas generated by the air pump is diverted through the straight air pipe and the three-way pipe, and then precisely sprayed from the first air blowing head and the second air blowing head onto the camera lens and the glass plate surface, quickly blowing away the attached metal debris and dust. At the same time, the soft brush of the wiping mechanism reciprocates under the drive of the power component, gently wiping away the stubborn debris remaining after blowing. The dual cleaning ensures that the lens is clear and the glass plate surface is flat. This design eliminates the need for regular manual cleaning, which reduces maintenance difficulty, saves labor costs, and avoids problems such as lens blurring and decreased accuracy of the detection reference surface caused by debris accumulation, ensuring the accuracy of subsequent test results and greatly improving the stability of equipment operation.

[0017] Thirdly, in this invention, the orderly batch feeding of metal connectors is achieved through a vibrating feeding tray, which continuously transports them to a rotating glass disk via a feeding track. No manual assistance is required for feeding. The rotating mechanism drives the glass disk to rotate smoothly, causing the workpieces to pass through positioning, inspection, and other stages in sequence, forming a continuous inspection process. This completely solves the problem of inspection interruption and stagnation in traditional equipment. This integrated feeding and inspection design significantly reduces the process interval time, significantly improves inspection efficiency, and can fully adapt to the inspection needs of mass production scenarios, reducing labor costs and production time.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-11In this embodiment of the invention, a metal connector production quality inspection device includes a first base 1 and a second base 2. A platform 5 is fixedly connected to one side of the interior of the first base 1. A rotating mechanism 7 is provided on one side of the platform 5, and a glass disk 6 is rotatably connected to the platform 5 via the rotating mechanism 7. A vibrating feed plate 3 is fixedly connected to the top of the second base 2. A feeding track 4 is fixedly connected to one side of the vibrating feed plate 3, and the feeding track 4 is located above the glass disk 6. A first support 8 is fixedly connected to one side of the platform 5 inside the first base 1. A first adjusting member 9 is provided on one side of a bracket 8. An infrared optical fiber 81 is slidably connected to one side of the first bracket 8 via the first adjusting member 9. A second adjusting member 10 is provided on the other side of the first bracket 8, and there are two second adjusting members 10. A first guide wheel 82 and a second guide wheel 83 are slidably connected to the other side of the first bracket 8 via the second adjusting member 10. The first guide wheel 82 and the second guide wheel 83 are arranged parallel to each other and are located at the outer and inner edges of the glass disk 6, respectively. A second bracket 11 is fixedly connected inside the first base 1 to the other side of the platform 5. A third adjusting member 12 is provided on one side of the second bracket 11. A camera 111 is slidably connected to one side of the second bracket 11 via the third adjusting member 12. The camera 111 is located above the glass disk 6. An air blowing mechanism 13 is provided on one side of the first base 1. A wiping mechanism 14 is provided on the mounting plate 131 of the air blowing mechanism 13. The air blowing mechanism 13 drives the mounting plate 131 to move radially along the glass disk, thereby driving the wiping mechanism 14 to perform radial scanning while reciprocating wiping. It should be noted that the industrial CCD camera 111 utilizes the height of the glass disk. With good light transmittance, objects can be placed on the inspection glass plate 6 via the vibrating feeder 3. A camera 111 can also be added to the bottom. If a camera 111 is also added to the bottom, an air blowing mechanism 13 and a wiping mechanism 14 can be added simultaneously. The inspection is carried out through the glass plate 6. This method is suitable for objects that need to be inspected on both sides and are free of oil stains. The image of the object to be inspected is obtained. Then, an industrial computer with software system compares the relationship between the image and the size to perform low-cost and high-efficiency automated inspection. This can reduce tedious and labor-intensive manual work and reduce human error in inspection, greatly improve the quality of product shipments, and increase competitiveness.

[0022] Please see Figure 11The rotating mechanism 7 includes a first motor 71, which is fixedly connected inside the base 5. A small gear 72 is fixedly connected to the output end of the first motor 71. A large gear 73 is meshed with one side of the small gear 72. Both the small gear 72 and the large gear 73 are rotatably connected to the upper side of the base 5. A shaft 74 is fixedly connected to the middle of the large gear 73. A fixed circular plate 75 is fixedly connected to the top of the shaft 74. The glass disk 6 is fixedly connected to the outside of the fixed circular plate 75. A balancing assembly 76 is provided between the fixed circular plate 75 and the base 5. The balancing assembly 76 includes support legs 761, which are fixedly connected to both sides of the bottom end of the fixed circular plate 75. Rollers 762 are rotatably connected to the bottom end of the support legs 761. The top of the platform 5 is provided with an annular groove 763, and the roller 762 is slidably connected inside the annular groove 763. During operation, the first motor 71 starts and drives the small gear 72 to rotate, which drives the large gear 73 to rotate slowly through gear meshing transmission. In turn, the shaft 74 drives the fixed circular plate 75 and the glass disk 6 to rotate synchronously, providing stable power for the continuous conveying and testing of the metal connectors. In the balancing assembly 76, the roller 762 at the bottom of the support leg 761 slides along the annular groove 763 of the platform 5, which not only provides stable support for the fixed circular plate 75, but also converts sliding friction into rolling friction, greatly reducing rotational resistance and preventing the glass disk 6 from tilting or shaking when rotating. This ensures the stability of the metal connectors on the glass disk 6 and provides a guarantee for subsequent accurate positioning and testing.

[0023] Please see Figure 10The first adjusting component 9 includes a first torsion wheel 91, which is rotatably connected to the upper side of the first bracket 8. A first lead screw 92 is fixedly connected to the bottom end of the first torsion wheel 91, and the first lead screw 92 is rotatably connected to one side of the interior of the first bracket 8. A first screw block 93 is threadedly connected to the outer surface of the first lead screw 92, and the first screw block 93 is slidably connected to the interior of the first bracket 8. The infrared optical fiber 81 is fixedly connected to one side of the first screw block 93 by bolts. The second adjusting component 10 includes a second torsion wheel 101, which is rotatably connected to the other side of the first bracket 8. Two second torsion wheels 101 are provided, and the two second torsion wheels 101 are arranged perpendicularly to the first torsion wheel 91. A second lead screw 102 is fixedly connected to one side of the second torsion wheel 101, and the second lead screw 102 is rotatably connected to the other side of the interior of the first bracket 8. The outer surface of the second lead screw 102 is threaded with a second screw block 103. The second screw block 103 is slidably connected inside the second adjusting member 10. The first guide wheel 82 and the second guide wheel 83 are rotatably connected to the two second screw blocks 103 respectively. Rotating the first torsion wheel 91 drives the first lead screw 92 to rotate, and through the threaded transmission, the first screw block 93 slides up and down along the first bracket 8, thereby adjusting the height of the infrared fiber 81. This ensures that the infrared fiber 81 can accurately sense metal connectors of different thicknesses, avoiding sensing failure or false triggering caused by improper height. Rotating the two second torsion wheels 101 can drive the corresponding second lead screw 102 to rotate, driving the second screw block 103 to move horizontally, thereby flexibly adjusting the distance between the first guide wheel 82 and the second guide wheel 83 to adapt to metal connectors of different sizes, achieving precise guidance and positioning of parts, and preventing parts from shifting on the glass disk 6.

[0024] Please see Figures 3-4The third adjusting component 12 includes a first cylinder 121, which is fixedly connected to the top of the second bracket 11. A lifting plate 122 is fixedly connected to the output end of the first cylinder 121. The camera 111 is fixedly connected to the lifting plate 122 by bolts. Limiting grooves 124 are formed on both sides of the interior of the second bracket 11. Limiting blocks 123 are slidably connected inside the limiting grooves 124, and the limiting blocks 123 are fixedly connected to both sides of the lifting plate 122. The first cylinder 121 drives the lifting plate 122 to move up and down, thereby moving the camera 111. The synchronous lifting mechanism allows for flexible adjustment of the distance between the camera 111 and the glass plate 6 according to testing requirements. This ensures that the camera 111 can clearly capture the surface details and dimensional information of the metal connector, meeting different testing accuracy requirements. It also facilitates subsequent cleaning of the camera 111's lens in conjunction with the air blowing mechanism 13 and the wiping mechanism 14. The limiting blocks 123 on both sides of the lifting plate 122 slide along the limiting grooves 124 of the second bracket 11, guiding and limiting the movement of the lifting plate 122. This prevents the lifting plate 122 from shifting, which could cause deviation in the camera 111's shooting angle and ensure the accuracy of the test image.

[0025] Please see Figures 4-5The blowing mechanism 13 includes a first power assembly 138, which is located on one side of the first base 1. An assembly plate 131 is movably connected to the first base 1 via the first power assembly 138. The wiping mechanism 14 is mounted on the assembly plate 131. A first blowing head 132 is fixedly connected to one side of the assembly plate 131, and a second blowing head 133 is fixedly connected to the other side of the assembly plate 131. One side of both the first and second blowing heads 132 and 133 has a beveled structure, respectively aligned with the lens of the camera 111 and the surface of the glass plate 6, facilitating the removal of surface dust. A three-way pipe 134 is fixedly connected to one side of both the first and second blowing heads 132 and 133. A straight air guide pipe 135 is fixedly connected to one side of the three-way pipe 134. A spring hose 136 is slidably extended out of the first base 1 and fixedly connected to one side of the straight air guide pipe 135. An air pump 137 is fixedly connected to one side of the flexible spring hose 136. The air pump 137 is fixedly connected to the back of the first base 1. When the air pump 137 is started, it generates high-pressure gas, which is then split through the flexible spring hose 136, the straight air pipe 135, and the three-way pipe 134 before being sprayed out from the first air blowing head 132 and the second air blowing head 133. The angled nozzle structure allows the airflow to accurately cover the lens of the camera 111 and the surface of the glass plate 6, quickly blowing away the attached metal debris and dust. The first power component 138 can drive the mounting plate 131 to move and adjust it to a reasonable position so that the first air blowing head 132 and the second air blowing head 133 can approach their respective cleaning targets. The flexible spring hose 136 can move and extend flexibly with the mounting plate 131 without affecting the stable delivery of airflow, ensuring the continuous and reliable operation of the air blowing cleaning function. During cleaning, the glass plate 6 is rotated by the rotating mechanism 7 to ensure that every area of ​​the glass plate 6 can be cleaned.

[0026] Please see Figure 4 The first power assembly 138 includes a second cylinder 1381, which is fixedly connected to the back of the first base 1. The output end of the second cylinder 1381 is fixedly connected to one side of the mounting plate 131. Connecting blocks 1382 are fixedly connected to both sides of the mounting plate 131. A sliding rod 1383 is fixedly connected to one side of the connecting block 1382. One side of the sliding rod 1383 slides through the first base 1. The second cylinder 1381 drives the mounting plate 131 to move smoothly in the horizontal direction, driving the blowing mechanism 13 and the wiping mechanism 14 to move synchronously and adjust them to a reasonable position. This ensures continuous cleaning of the camera 111 lens and the glass plate 6, avoiding cleaning dead corners. The connecting blocks 1382 on both sides of the mounting plate 131 cooperate with the sliding rod 1383 to guide the movement of the mounting plate 131, ensuring smooth movement of the mounting plate 131 and avoiding displacement of the cleaning position due to shaking. At the same time, it enhances the structural stability of the mounting plate 131 and extends the service life of the equipment.

[0027] Please see Figures 4-9 The wiping mechanism 14 includes a second power component 146, which is located inside the mounting plate 131. Both the upper and lower sides of the mounting plate 131 are slidably connected to linkage plates 143 via the second power component 146. A shock absorber 144 is fixedly connected to the top of the linkage plate 143. The shock absorber 144 includes a shock-absorbing spring and a damper. A mounting plate 142 is fixedly connected to the top of the shock absorber 144. A soft brush 141 is bolted to the top of the mounting plate 142. A slider 145 is fixedly connected to the bottom of the mounting plate 142, located on one side of the shock absorber 144. One side of the slider 145 is slidably connected inside the linkage plate 143. The second power component 146 drives the linkage plate 143 to reciprocate, thereby moving the soft brush 141. The synchronized motion gently wipes the lens of the camera 111 and the surface of the glass disk 6, and works in conjunction with the air blowing mechanism 13 to achieve deep cleaning and thoroughly remove stubborn debris. The shock absorber 144 includes a telescopic rod and a damping spring sleeved on the outside of the telescopic rod, which provides normal buffering force when the soft brush 141 contacts the surface of the glass disk 6, so that the tip of the soft brush 141 maintains a constant micro-contact state with the glass disk 6. The shock absorber 144 can buffer the pressure during wiping and prevent the soft brush 141 from excessively contacting the cleaning target and causing damage. The mounting plate 142 is slidably connected to the linkage plate 143 through the slider 145, which can balance the position of the soft brush 141 and prevent the position from shifting, affecting the cleaning, thereby ensuring the fit during cleaning. The bolt fixing method facilitates the disassembly and replacement of the soft brush 141 and reduces maintenance costs.

[0028] Please see Figures 4-9The second power assembly 146 includes a second motor 1461, a drive gear 1462, and a first driven gear 1463 and a second driven gear 1464 respectively meshing with the drive gear 1462. A first half-gear 1465 and a second half-gear 1466 are fixedly connected to the shaft ends of the first driven gear 1463 and the second driven gear 1464, respectively. The teeth of the first half-gear 1465 and the second half-gear 1466 are complementary in phase. A transmission rack 1467 is slidably connected to the mounting plate 131, and the transmission rack 1467 has relatively opposing configurations. The first and second tooth surfaces, the first half gear 1465 and the second half gear 1466, drive the transmission rack 1467 to reciprocate linearly along the mounting plate 131 by alternating intermittent meshing with the first tooth surface and the second tooth surface respectively. The second power assembly 146 is located inside the mounting plate 131. The upper and lower sides of the mounting plate 131 are slidably connected to the linkage plate 143 through the second power assembly 146. The top of the linkage plate 143 is fixedly connected to the shock absorber 144, and the top of the shock absorber 144 is fixedly connected to the mounting plate 142. A soft brush 141 is bolted to the top of the mounting plate 142. A slider 145 is fixedly connected to the bottom of the mounting plate 142 on one side of the shock absorber 144. One side of the slider 145 is slidably connected to the inside of the linkage plate 143. The second motor 1461 is fixedly connected to one side of the top of the mounting plate 131. The drive gear 1462 is fixedly connected to the output end of the second motor 1461. The drive gear 1462 is rotatably connected to the inside of the mounting plate 131. A transmission plate 14671 is fixedly connected to one side of the transmission rack 1467. A linkage block 14674 is fixedly connected to one side of plate 14671. One side of the linkage block 14674 slides out of the assembly plate 131 and is fixedly connected to the linkage plate 143. Stop blocks 14672 are fixedly connected to both sides of the transmission rack 1467. The first half gear 1465 and the second half gear 1466 are in movable contact with the two stop blocks 14672. A limit guide rod 14673 is fixedly connected to the side of the transmission rack 1467 away from the transmission plate 14671. One side of the limit guide rod 14673 is slidably connected inside the assembly plate 131.The second motor 1461 starts and drives the drive gear 1462 to rotate. Through gear meshing, it drives the first driven gear 1463 and the second driven gear 1464 to rotate in the same direction, thereby causing the first half gear 1465 and the second half gear 1466 to rotate synchronously in the same direction. Since the first half gear 1465 and the second half gear 1466 intermittently mesh with the transmission rack 1467, the transmission rack 1467 can be driven to reciprocate along the mounting plate 131. The transmission rack 1467 drives the linkage plate 143 to reciprocate through the transmission plate 14671 and the linkage block 14674, providing stable power for the wiping mechanism 14. This ensures that the soft brush 141 always maintains a constant moving speed and wiping frequency, thus avoiding incomplete cleaning or lens damage caused by sudden changes in wiping force. The soft brush 141 can fully cover the lens of the camera 111 and the surface of the glass disk 6, leaving no blind spots. Simultaneously, stable power output ensures the soft brush 141 maintains uniform contact with the cleaning target, effectively removing stubborn debris and dust. Combined with the pre-treatment function of the air blowing mechanism 13, it achieves dual high-efficiency cleaning through blowing and wiping, significantly improving cleaning efficiency and cleanliness. This ensures the lens remains clear and the surface of the glass disk 6 is flat and free of impurities, providing a stable and reliable environment for subsequent testing and guaranteeing the accuracy of test results. The stop block 14672 limits the sliding stroke of the transmission rack 1467 to prevent excessive movement, and the limit guide rod 14673 guides the sliding of the transmission rack 1467, ensuring smooth transmission and precise reciprocating motion of the wiping mechanism 14.

[0029] The working principle of this invention is as follows: Before use, based on the size of the metal connector to be tested, the first torsion wheel 91 is rotated by the first adjusting member 9, which drives the first lead screw 92 to rotate, causing the first screw block 93 to slide up and down along the first bracket 8, thereby adjusting the height of the infrared optical fiber 81 until the optical fiber can be accurately blocked by the workpiece, avoiding missed or excessive shots due to improper height. The two second torsion wheels 101 are rotated, respectively driving the corresponding second lead screw 102 to rotate, driving the second screw block 103 to move horizontally, flexibly adjusting the distance between the first guide wheel 82 and the second guide wheel 83 to match the size of the workpiece, preparing for workpiece positioning. The first cylinder 121 of the third adjusting member 12 is activated, driving the lifting plate 122 to lift the camera 111, adjusting the distance between the camera 111 and the glass... The distance between the glass plate 6 and the workpiece surface ensures clear imaging of details and dimensions. Simultaneously, the limiting blocks 123 on both sides of the lifting plate 122 slide along the limiting grooves 124 of the second bracket 11, ensuring smooth movement and precise shooting angles for the camera 111. After starting the equipment, the vibrating feeding plate 3 transports the metal connectors in an orderly batch to the unloading track 4. The workpieces fall smoothly onto the glass plate 6 driven by the rotating mechanism 7 via the unloading track 4. Under the coordinated guidance of the first guide wheel 82 and the second guide wheel 83, they are precisely positioned in the detection area of ​​the glass plate 6, preventing deviation or tilting. The first motor 71 starts and drives the small gear 72 to rotate, which in turn drives the large gear 73 to rotate slowly through gear meshing. This, in turn, drives the fixed circular plate 75 and the glass plate 6 to rotate synchronously via the shaft 74. The rollers 762 of the fixed circular plate 75 bottom support leg 761 slide along the annular groove 763 of the platform 5 to ensure the smooth rotation of the glass disk 6 and provide stable power for continuous workpiece conveying and inspection. When the workpiece rotates with the glass disk 6 to below the infrared fiber optic 81, the infrared fiber optic 81 monitors the workpiece position in real time. After confirming that the part is placed reasonably, it triggers the camera 111 to take pictures after a delay of a few seconds. All captured images are transmitted to the industrial computer in real time. The supporting software system compares the image with the preset size parameters to complete the automated inspection and determine whether the workpiece is qualified. When it is necessary to clean the camera and glass disk 6 periodically, the position of the assembly plate 131 is adjusted by the second cylinder 1381 of the first power assembly 138, so that the first air head 132, the second air head 133 and the soft bristles are connected. Brush 141 is brought close to the lens of camera 111 and the glass plate 6 respectively. During the inspection, air pump 137 continuously starts to generate high-pressure gas. After being split through spring hose 136, straight air pipe 135, and three-way pipe 134, the gas is precisely sprayed from the first air blowing head 132 and the second air blowing head 133 of the inclined structure onto the surface of camera 111 lens and glass plate 6, quickly blowing away the attached metal debris and dust. At the same time, the second cylinder 1381 of the first power component 138 drives the assembly plate 131 to move smoothly in the horizontal direction, driving the blowing mechanism 13 and the wiping mechanism 14 to move synchronously, avoiding cleaning dead corners. The spring hose 136 moves flexibly and extends and retracts with the movement of the assembly plate 131 without affecting the stable delivery of airflow. Meanwhile, the second motor 1461 of the wiping mechanism 14 starts.The drive gear 1462 rotates, which in turn drives the first driven gear 1463 and the second driven gear 1464 to rotate in the same direction. This causes the first half gear 1465 to rotate until it meshes with the toothed area of ​​the transmission rack 1467, driving the transmission rack 1467 to move to the left. Subsequently, the first half gear 1465 rotates to the toothless area and disengages. At this time, the toothed area of ​​the second half gear 1466 rotates to mesh with the second toothed area of ​​the transmission rack 1467, driving the transmission rack 1467 to move to the right. Through the alternating meshing of the first half gear 1465 and the second half gear 1466, continuous switching of power and reversal of direction are achieved. The transmission rack 1467 is connected to the transmission plate 14671 and the linkage block 14674. The linkage plate 143 and the soft brush 141 reciprocate in a regular motion, gently wiping away stubborn debris remaining on the lens and glass plate 6 surface. The shock absorber 144 buffers the wiping pressure, preventing the soft brush 141 from excessively contacting the cleaning target and causing damage. The second power unit 146 ensures that the soft brush 141 maintains a constant moving speed and wiping frequency, avoiding incomplete cleaning or lens damage caused by inconsistent wiping force, while allowing the soft brush 141 to fully cover the camera lens 111 and the glass plate 6 surface, leaving no blind spots. At the same time, the stable power output ensures that the soft brush 141 maintains uniform contact with the cleaning target, effectively removing attached stubborn debris and dust, greatly improving cleaning efficiency and cleanliness, and ensuring that the lens remains clear and the glass plate 6 surface is clean. The surface is flat and free of impurities, providing a stable and reliable environment for subsequent testing and ensuring the accuracy of the test results. During the cleaning process, the glass disk 6 rotates synchronously to ensure that every area of ​​its placement surface is thoroughly cleaned. The advantage of this technical solution is that the design of using an industrial CCD camera 111 with a high-transmittance glass disk 6 allows for flexible selection of single-sided or double-sided inspection modes, adapting to the inspection needs of oil-free metal connectors. Combined with an industrial computer and supporting software system, it achieves low-cost, high-efficiency automated inspection, significantly reducing tedious and time-consuming manual work, reducing human error, and significantly improving product quality and market competitiveness. It solves the problems of low efficiency and large errors in traditional manual inspection. Through the coordinated limiting of the first guide wheel 82 and the second guide wheel 83, in conjunction with... Real-time position monitoring of the infrared fiber optic cable 81 enables precise positioning of the metal connector within the detection area of ​​the glass disk 6, effectively avoiding image deviation caused by workpiece offset or tilt, and ensuring the accuracy and reliability of the detection results. Simultaneously, the first adjusting component 9 and the second adjusting component 10 can flexibly adjust the height of the infrared fiber optic cable 81 and the spacing between the guide wheels to adapt to metal connectors of different sizes and thicknesses, significantly expanding the applicability of the equipment and solving the shortcomings of poor positioning effect and insufficient adaptability of existing detection equipment. The air blowing mechanism 13 and the wiping mechanism 14 work together to form a dual cleaning mode of blowing and wiping. The air blowing mechanism 13 quickly removes most metal debris and dust, while the soft brush 141 of the wiping mechanism 14 performs regular reciprocating motion under stable power drive, eliminating cleaning dead corners.Simultaneously, the rotation of the glass disk 6, in conjunction with the movement of the assembly plate 131, ensures thorough cleaning, eliminating the need for regular manual cleaning, reducing maintenance difficulty and labor costs, and preventing problems such as lens blurring and decreased accuracy of the inspection table reference surface caused by debris accumulation, thus ensuring continuous and stable equipment operation. The vibrating feeder 3 enables the orderly batch feeding of metal connectors, which are continuously conveyed to the rotating glass disk 6 via the unloading track 4, eliminating the need for manual assistance. The rotating mechanism 7 drives the glass disk 6 to rotate smoothly, facilitating workpiece inspection, solving the problem of inspection interruptions and stagnation in traditional equipment, significantly reducing process interval time, and significantly improving inspection efficiency, fully adapting to the inspection needs of mass production scenarios.
