Description

Technical Field

[0001] This utility model relates to the field of keyboard inspection technology, specifically to a device for detecting keyboard appearance defects. Background Technology

[0002] In the keyboard production process, quality inspection of the finished keyboard must be carried out before shipment. Each key needs to be pressed to test its rebound and contact continuity to ensure that each key can function properly. Mechanical devices are used to simulate key presses, and sensors are used to detect changes in the key status. Alternatively, a vision inspection system is used to inspect the keyboard's appearance, key positions, colors, etc., to improve inspection efficiency and accuracy.

[0003] However, in the existing technology, when inspecting the appearance of a keyboard, it is necessary to lay the keyboard flat. However, the molds for placing the keyboard are mostly concave, which makes it inconvenient for staff to remove the keyboard after inspection. In addition, the sizes of keyboards are different, and the molds cannot be uniformly adapted when inspecting different models of keyboards. Summary of the Invention

[0004] The purpose of this invention is to provide a keyboard appearance defect detection device that is convenient for placing and picking up keyboards and is compatible with different keyboard models, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a keyboard appearance defect detection device, comprising an installation component, a transport component, and a detection component. The transport component is mounted on the installation component for picking up, placing, and moving the keyboard for detection. The detection component is mounted on the installation component for photographing and detecting the keyboard appearance.

[0006] Furthermore, the transport assembly includes a moving assembly and a clamping assembly. The moving assembly is disposed on the mounting assembly, and the clamping assembly is disposed within the moving assembly. The moving assembly includes a slide rail, a screw, a motor, a slider, a concave plate, a round rod, a mounting block, a motor, and a rectangular plate. The slide rail is disposed on the mounting assembly. The screw is rotatably mounted within the slide rail. The motor is fixedly mounted on one outer wall of the slide rail, and the output end of the motor is fixedly connected to one end of the screw. The slider is slidably mounted within the slide rail and is threadedly connected to the screw. The concave plate is fixedly mounted on the top of the slider. The round rod is rotatably mounted within the concave plate. The mounting block is fixedly sleeved on the round rod. The motor is fixedly mounted on one outer wall of the concave plate, and the output end of the motor is fixedly connected to one end of the round rod. The rectangular plate is fixedly mounted on one outer wall of the mounting block.

[0007] Furthermore, a support block is fixedly installed at the bottom of the rectangular plate, and a pad is fixedly installed at the bottom of the support block.

[0008] Furthermore, the clamping assembly includes two sliding openings, two clamping plates, two connecting plates, a fixing plate, and two springs. Both sliding openings are located at the top of the rectangular plate, both clamping plates are located at the top of the rectangular plate, the two connecting plates are slidably installed in the two sliding openings, the fixing plate is fixedly installed at the bottom of the rectangular plate, and both springs are fixedly installed on the outer wall of the fixing plate. The two springs are respectively fixedly connected to the outer wall of the two connecting plates on the side closest to each other.

[0009] Furthermore, the mounting assembly includes a base, a mounting plate, and a light shield. The mounting plate is fixedly mounted on the top of the base, the light shield is fixedly mounted on the mounting plate, the light shield is fixedly connected to the top of the base, and the slide rail is fixedly mounted on the top of the base.

[0010] Furthermore, the material of the light shield is light-shielding glass.

[0011] Furthermore, the detection assembly includes two mounting frames, six mounting brackets, an industrial camera, and four supplementary lights. The two mounting frames are fixedly mounted on the top of the base, the six mounting brackets are fixedly mounted in the two mounting frames respectively, the industrial camera is evenly distributed on the six mounting brackets, and the four supplementary lights are fixedly mounted in the two mounting frames respectively.

[0012] In summary, due to the adoption of the above-mentioned technologies, the beneficial effects of this utility model are:

[0013] This invention features a transport component. When the motor is started, it drives a round rod to rotate counter-clockwise. The rod then rotates a mounting block, which in turn moves a rectangular plate around the rod. When the rectangular plate rotates out of the concave plate, the motor stops, and the keyboard is picked up. The clamping plate is then moved, causing a connecting plate to move away from the center within the sliding opening. As the connecting plate moves, it pulls a spring, causing the spring to deform and accumulate elastic force. The keyboard is then placed on the rectangular plate. The clamping plate is released, causing the spring to lose its tension and release its elastic force. The spring then pulls the connecting plate to move back to its original position. The connecting plate then moves the clamping plate to hold and fix the keyboard. The motor is then started, causing the round rod to rotate in the opposite direction, moving the rectangular plate back into the concave plate to reset. This design offers advantages such as convenient keyboard placement and retrieval, and compatibility with different keyboard models.

[0014] This invention, through the setting of a detection component, starts a motor, which drives a screw to rotate. The rotating screw moves a slider, which slides within a slide rail. The slider moves a concave plate and the keyboard into a mounting frame. Once the keyboard is in the mounting frame, a supplementary light and an industrial camera are activated. The supplementary light illuminates the keyboard, and the industrial camera takes a picture of the keyboard. The industrial camera transmits the captured image to an external computer for storage and display. More specifically, it has the advantages of providing supplementary lighting to the outside of the keyboard, making the keyboard surface brighter and easier to spot defects, and enabling photographic inspection of the keyboard.

[0029] Working principle:

[0030] Step 1: Clamp and place the device. Start the motor 208. The motor 208 drives the round rod 206 to rotate counterclockwise. The round rod 206 drives the mounting block 207 to rotate. The mounting block 207 drives the rectangular plate 209 to move. The rectangular plate 209 rotates around the round rod 206. When the rectangular plate 209 rotates out of the concave plate 205, stop the motor 208 and pick up the keyboard. Move the clamping plate 211. The clamping plate 211 drives the connecting plate 212 to move within the sliding opening 210 and away from the center. When the connecting plate 212 moves, it pulls the spring 214. The spring 214 deforms under the pull and accumulates elastic force. The keyboard is placed on the rectangular plate 209. The clamping plate 211 is released, the spring 214 loses the pulling force and releases the elastic force. The spring 214 pulls the connecting plate 212 to move and reset. The connecting plate 212 drives the clamping plate 211 to move and clamp and fix the keyboard. The starting motor 208 drives the round rod 206 to rotate in the opposite direction, which drives the rectangular plate 209 to move into the concave plate 205 to reset.

[0031] Step 2: Movement detection. Start motor 203, which drives screw 202 to rotate. Screw 202 rotates and drives slider 204 to move. Slider 204 slides within slide rail 201, and slider 204 drives concave plate 205 and keyboard to move into mounting frame 301. Once the keyboard is inside mounting frame 301, turn on fill light 304 and industrial camera 303. Fill light 304 illuminates the keyboard, and industrial camera 303 takes a picture of the keyboard. Industrial camera 303 transmits the captured picture to an external computer for storage and displays it on a monitor.
