[0001] This utility model relates to the field of keyboard technology, specifically to a macro imaging lightbox module suitable for detecting keyboard appearance defects. Background Technology

[0002] A keyboard is a device used to input instructions and data for operating computer equipment. It also refers to a set of function keys arranged by the system to operate a machine or device. The keyboard is the most commonly used and primary input device. Through the keyboard, English letters, Chinese characters, numbers, punctuation marks, etc., can be input into the computer, thereby issuing commands and inputting data. There are also keyboards with various shortcut keys. Over time, independent products with various shortcut functions have gradually appeared on the market, sold separately with dedicated drivers and configuration software, enabling personalized operation even on compatible computers.

[0003] However, in the existing technology, after the keyboard is manufactured and assembled, the keycaps on the keyboard are inspected. However, the inspection is mostly done by visual inspection or by taking pictures from above the keyboard. Since keycaps have five sides, it is easy to miss damaged parts on the sides during inspection, resulting in omissions. Summary of the Invention

[0004] The purpose of this invention is to provide a macro imaging lightbox module suitable for detecting keyboard appearance defects. It has the advantage of adjusting the shooting angle and taking pictures of the inclined and top surfaces of the keycaps from multiple directions, reducing the chance of missing damaged keycaps due to incomplete shooting, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a macro imaging lightbox module suitable for keyboard appearance defect detection, comprising a detection box assembly, two vertical imaging assemblies and a horizontal imaging assembly. The two vertical imaging assemblies are both disposed within the detection box assembly for imaging and detecting the appearance of the vertical surface of the keyboard keycaps, and the horizontal imaging assembly is disposed within the detection box assembly for imaging and detecting the appearance of the horizontal surface of the keyboard keycaps.

[0006] Furthermore, the longitudinal imaging assembly includes a mounting plate, a pneumatic push rod, a C-shaped plate, a round rod, a connecting block, a telescopic rod, an industrial camera, a linkage block, a linkage rod, and an LED light. The mounting plate is disposed inside the detection box assembly. The pneumatic push rod is fixedly mounted on the bottom inner wall of the mounting plate. The C-shaped plates are evenly distributed on the top inner wall of the mounting plate. The round rod is fixedly mounted on the C-shaped plate.

The linkage block is fixedly mounted on the industrial camera. The linkage rod is fixedly mounted on the linkage block. The LED light is fixedly mounted on the outer wall of the industrial camera.

[0007] Furthermore, the mounting plate is bent and has a hook-shaped cross-section.

[0008] Furthermore, the detection box assembly includes a base, a top plate, four mounting rods, four baffles, and four cylinders. The top plate is disposed on the top of the base, the four mounting rods are all fixedly installed on the bottom of the top plate, the four baffles are respectively fixedly installed between the four mounting rods, the four cylinders are all fixedly installed on the top of the base, and the output ends of the four cylinders are all fixedly connected to the bottom of the top plate.

[0009] Furthermore, the baffle is made of a light-shielding material.

[0010] Furthermore, the horizontal shooting assembly includes a slide rail, a screw, a slider, a first motor, a second C-shaped plate, a rotating rod, a rotating block, a second industrial camera, two second LED lights, and a motor. The slide rail is located below the top plate. The screw is rotatably mounted inside the slide rail. The slider is threaded onto the screw. The first motor is fixedly mounted on one side of the outer wall of the slide rail. The second C-shaped plate is fixedly mounted on the bottom of the slider.

[0012] In summary, due to the adoption of the above-mentioned technologies, the beneficial effects of this utility model are: This invention features a longitudinal imaging component. When a pneumatic push rod is activated, it retracts and pulls a telescopic rod. The telescopic rod, pulled downwards and flips, simultaneously causing a connecting block to rotate. This rotation of the connecting block on the round rod causes the industrial camera to flip, changing its shooting angle. The industrial camera then moves a linkage block, which in turn moves a linkage rod. Through the linkage block and linkage rod, the series-connected industrial camera moves synchronously, providing the advantage of photographing and inspecting the longitudinal slope and top surface of the keycap, reducing the risk of missing or damaged keycaps due to incomplete imaging.

[0013] This invention features a horizontal shooting component. Starting a motor drives a screw to rotate, which in turn moves a slider that is engaged with it. The slider slides within a slide rail, causing an industrial camera to move and adjust its shooting position. Starting a motor then drives a rotating rod to rotate, which in turn rotates a rotating block, causing the industrial camera to flip. This design allows for adjusting the shooting angle and capturing images of the keycap's horizontal sloping and top surfaces. Attached Figure Description

Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0017] This utility model provides, for example Figures 1-5 As shown, a macro imaging lightbox module suitable for keyboard appearance defect detection includes a detection box assembly 1, two vertical imaging components 2 and a horizontal imaging component 3. The two vertical imaging components 2 are both set inside the detection box assembly 1 for imaging and detecting the appearance of the vertical surface of the keyboard keycaps, and the horizontal imaging component 3 is set inside the detection box assembly 1 for imaging and detecting the appearance of the horizontal surface of the keyboard keycaps.

[0018] Additionally, the longitudinal imaging assembly 2 includes a mounting plate 201, a pneumatic push rod 202, a C-shaped plate 203, a round rod 204, a connecting block 205, a telescopic rod 206, an industrial camera 207, a linkage block 208, a linkage rod 209, and an LED light 210. The mounting plate 201 is disposed within the detection box assembly 1. The pneumatic push rod 202 is fixedly mounted on the bottom inner wall of the mounting plate 201. The C-shaped plates 203 are evenly distributed on the top inner wall of the mounting plate 201. The round rod 204 is fixedly mounted on the C-shaped plates 203.

The industrial camera 207 drives the linkage block 208 to move, and the linkage block 208 drives the linkage rod 209 to move. Through the linkage block 208 and the linkage rod 209, the industrial camera 207 is moved synchronously in series. This has the advantage of taking pictures and detecting the longitudinal inclined surface and top surface of the keycap, reducing the risk of missing or damaging the keycap due to incomplete shooting.

[0019] In addition, the mounting plate 201 is bent and has a hook-shaped cross-section.

[0020] like Figure 1 As shown, the detection box assembly 1 includes a base 101, a top plate 102, four mounting rods 103, four baffles 104, and four cylinders 105. The top plate 102 is disposed on the top of the base 101. The four mounting rods 103 are all fixedly installed on the bottom of the top plate 102. The four baffles 104 are respectively fixedly installed between the four mounting rods 103. The four cylinders 105 are all fixedly installed on the top of the base 101, and the output ends of the four cylinders 105 are all fixedly connected to the bottom of the top plate 102.

[0021] In addition, the baffle 104 is made of a light-shielding material.

[0022] like Figure 1As shown, in some embodiments, the horizontal shooting assembly 3 includes a slide rail 301, a screw 302, a slider 303, a motor 304, a C-shaped plate 305, a rotating rod 306, a rotating block 307, an industrial camera 308, two LED lights 309, and a motor 310. The slide rail 301 is located below the top plate 102. The screw 302 is rotatably mounted inside the slide rail 301. The slider 303 is threaded onto the screw 302. The motor 304 is fixedly mounted on one outer wall of the slide rail 301. The C-shaped plate 305 is fixedly mounted on the bottom of the slider 303. The rotating rod 306 is rotatably mounted on the C-shaped plate 305. The rotating block 307 is fixedly sleeved on the rotating rod 306.

The motor 310 is fixedly mounted on one side of the outer wall of the C-shaped plate 305. The output end of the motor 310 is fixedly connected to one end of the rotating rod 306. More specifically, when the motor 304 is started, the motor 304 drives the screw 302 to rotate. The screw 302 drives the slider 303, which is engaged with it, to move. The slider 303 slides in the slide rail 301. The slider 303 drives the industrial camera 308 to move and adjust the shooting position. When the motor 310 is started, the motor 310 drives the rotating rod 306 to rotate. The rotating rod 306 drives the rotating block 307 to rotate and flip. The rotating block 307 drives the industrial camera 308 to flip.

The sliding plate 5 moves in the rectangular opening 4, and the sliding plate 5 moves the industrial camera 207 and the industrial camera 308, which has the advantage of moving and adjusting the shooting position.

[0024] Working principle: Step 1: Place the shield. Place the keyboard on the base 101. At this time, start the cylinder 105. The cylinder 105 retracts and moves the top plate 102 down. The movement of the top plate 102 moves the mounting rod 103. The mounting rod 103 moves the baffle 104. The baffle 104 and the top plate 102 work together to shield the keyboard from the light. At this time, turn on the LED light 210 and LED light 309 to illuminate the keyboard.

[0025] Step 2: Move and adjust. Start motor 26. Motor 26 drives gear 7 to rotate. When gear 7 rotates, it meshes with gear plate 8, causing the teeth of gear 7 to roll on gear plate 8 and drive motor 26 and slide plate 5 to move. Slide plate 5 moves within rectangular opening 4. Slide plate 5 moves industrial camera 1207 and industrial camera 2308 to adjust the shooting position.

[0026] Step 3: Longitudinal inspection. Activate the pneumatic push rod 202. The pneumatic push rod 202 retracts and pulls the telescopic rod 206. The telescopic rod 206 moves downward and flips under the pull of the pneumatic push rod 202. The downward flip of the telescopic rod 206 also drives the connecting block 205 to rotate. The connecting block 205 rotates on the round rod 204 and drives the industrial camera 207 to flip, changing the shooting angle of the industrial camera 207. The industrial camera 207 drives the linkage block 208 to move, and the linkage block 208 drives the linkage rod 209 to move. Through the linkage block 208 and the linkage rod 209, the series-connected industrial camera 207 moves synchronously, taking pictures of the longitudinal inclined surface and top surface of the keycap for inspection.

[0027] Step 4: Lateral Inspection. Start motor 304. Motor 304 drives screw 302 to rotate. Screw 302 drives slider 303, which is engaged with it, to move. Slider 303 slides within slide rail 301. Slider 303 drives industrial camera 308 to move and adjust the shooting position. Start motor 310. Motor 310 drives rotating rod 306 to rotate. Rotating rod 306 drives rotating block 307 to rotate and flip. Rotating block 307 drives industrial camera 308 to flip and adjust the shooting angle to take pictures of the lateral slope and top surface of the keycap for inspection.
