Technical Field

[0001] This utility model relates to the field of keyboard processing technology, specifically a keyboard detection device for keyboard processing. Background Technology

[0002] A keyboard is a device for inputting instructions and data to operate computer equipment. It also refers to a set of function keys (such as typewriter keyboards) arranged by a 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. During the manufacturing process, it is necessary to check whether the appearance of the keyboard meets the standard specifications. Currently, most keyboards on the market are manufactured in factories. Due to mass production, quality control is prone to be lax, resulting in poor quality of the final product.

[0026] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of this disclosure as detailed in the appended claims.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0028] like Figures 1 to 6 As shown in the figure, this embodiment proposes a keyboard testing device for keyboard processing, including a workbench 1, with upright plates 2 fixedly connected to both ends of the top of the workbench 1, wherein the upright plates 2 can be fixedly connected by welding.

[0029] The top of the workbench 1 is equipped with a conveying structure 3, which includes a rotating shaft 31 symmetrically arranged at both ends of the upright plate 2. The rotating shaft 31 is rotatably inserted between the two upright plates 2. The two ends of the rotating shaft 31 are fixedly connected to the rotating rollers 32. A conveyor belt 33 is sleeved between the two rotating rollers 32. There are two conveyor belts 33, which are symmetrically arranged. The conveyor belt 33 and the rotating rollers 32 are made of appropriate materials and coatings to increase friction and prevent the conveyor belt 33 from running off-center, thereby improving the stability of the conveyor belt 33. The front end of one rotating shaft 31 extends to the outside of the upright plate 2 and the end is fixedly connected to a motor 34. The motor 34 is equipped with a motor frame on its outside and is fixedly connected to the surface of the upright plate 2. By starting the motor 34, the rotating shaft 31 is driven to rotate. The rotating shaft 31 drives the rotating rollers 32 at both ends to rotate. The rotating rollers 32 drive the rotating rollers 32 at the other end to rotate through the conveyor belt 33, thereby conveying the keyboard.

[0030] The top of the conveying structure 3 is provided with a guide structure 4. The guide structure 4 includes a bracket 41 fixedly connected to the middle between the two end plates 2. The bracket 41 can be fixed by bolts. Two-way screws 42 are rotatably inserted into the upper part of both ends of the inner wall of the bracket 41. One end of the two-way screws 42 extends to the outside of the bracket 41 and is fixedly connected to the end of the motor 43. A motor frame 43 is provided on the outside of the motor 43 and is fixedly connected to the outer surface of the bracket 41.

[0031] The two ends of the bidirectional screw 42 are threadedly connected to vertical plates 44, and the bottom of the vertical plates 44 is fixedly connected to guide plates 45. The guide plates 45 can be fixedly connected by welding. The bidirectional screw 42 is driven to rotate by the motor 43, which in turn drives the two vertical plates 44 to move towards each other, thereby adjusting the distance between the two guide plates 45. This allows the two guide plates 45 to limit and fix the finished keyboard, preventing it from shifting during transportation.

[0032] A rubber buffer pad is provided on the opposite side of the guide plate 45. The rubber buffer pad can protect the outer perimeter of the keyboard. Multiple limiting rods 46 are fixedly connected to the opposite side of the guide plate 45. The limiting rods 46 can be fixedly connected by welding. The limiting rods 46 are inserted into the upright plate 2. The setting of the limiting rods 46 facilitates the limiting and guiding of the movement of the guide plate 45.

[0033] The workbench 1 is equipped with a lifting structure 5 at one end. The lifting structure 5 includes a through hole 51 at one end of the top of the workbench 1, which is located between the two conveyor belts 33. A bracket 52 is fixedly connected to one end of the bottom of the workbench 1. The bracket 52 can be fixedly connected by welding. Electric push rods 53 are fixedly installed at the four corners of the top of the inner wall of the bracket 52. The output end of the electric push rods 53 is fixedly connected to a lifting plate 54, which can be fixed by bolts. The lifting plate 54 is inserted into the through hole 51. By activating the electric push rods 53, the lifting plate 54 is driven to rise and the keyboard is taken away from the top of the two conveyor belts 33, making the keyboard more stable during testing and improving the testing effect.

[0034] The workbench 1 has a detection structure 6 at one end. The detection structure 6 includes a bracket 61 fixedly connected to the top end between the two end plates 2. The bracket 61 can be fixed by bolts. An image acquisition device 62 is installed in the middle of the top of the inner wall of the bracket 61. A display 63 and an alarm 64 are installed on the top of the bracket 61. An image processor 65 and a controller 66 are installed at both ends of the top of the inner wall of the bracket 61. All of the above are existing technologies and will not be described in detail here. The image acquisition device 62 and the image processor 65 are electrically connected. The image processor 65 and the controller 66 are electrically connected. The controller 66 and the display 63 are electrically connected.

[0035] The workbench 1 has a collection structure 7 at one end. The collection structure 7 includes a groove 71 opened on the side of the upright plate 2 near the image acquisition device 62. An electric push rod 72 is fixedly installed at one end of the upright plate 2. The electric push rod 72 can be fixed by bolts. The output end of the electric push rod 72 extends into the groove 71 and is fixedly connected to a push plate 73 at the end. The push plate 73 can be fixed by bolts, and positioning blocks are fixedly connected to both ends of the push plate 73 by welding. When a keyboard is detected to be defective, the controller 66 receives a signal and controls the electric push rod 72 to start. The electric push rod 72 drives the push plate 73 to move. The positioning blocks at both ends of the push plate 73 can position the keyboard and then push the defective keyboard out of the lifting plate 54.

[0036] Limiting rods 74 are fixedly connected to both ends of the push plate 73. The limiting rods 74 can be fixedly connected by welding. The limiting rods 74 are inserted into the upright plate 2. A through hole 75 is opened on the other end of the upright plate 2 near the groove 71. The setting of the limiting rods 74 facilitates the limiting and guiding of the movement of the push plate 73.

[0037] A collection box 8 is provided on one side of the rear end of the workbench 1. The collection box 8 is located below the second through hole 75. Defective keyboards are pushed into the collection box 8 through the second through hole 75 for sorting and collection.

[0038] In practical implementation, the keyboard to be inspected is first placed on the surface of two conveyor belts 33. Then, motor 43 is started, driving a bidirectional screw 42 to rotate, which in turn moves two vertical plates 44 towards each other, adjusting the distance between the two guide plates 45. This allows the guide plates 45 to limit and fix the keyboard, preventing deviation during transport. Next, motor 34 is started, driving a rotating shaft 31 to rotate. The shaft 31 drives two rollers 32 at both ends to rotate, which in turn drive the other roller 32 via the conveyor belt 33. This limits and guides the keyboard during transport, ensuring stability. Finally, when the keyboard moves to the inspection station directly below the image acquisition unit 62, the electric push rod is activated. The lifting plate 54 is raised by the first 53, which lifts the keyboard away from the top of the two conveyor belts 33. Then, the image acquisition device 62 is activated to capture an image of the keyboard and transmits the signal to the image processor 65. The image is compared with the standard keyboard image, and the display 63 can quickly and intuitively detect whether the keyboard meets the standard. Normal keyboards are directly conveyed to the next process. When a keyboard is found to be unqualified, the controller 66 receives a signal and controls the second electric push rod 72 to start. The second electric push rod 72 drives the push plate 73 to move. The positioning blocks at both ends of the push plate 73 can position the keyboard and then push the unqualified keyboard from the lifting plate 54 to the through hole 75, and then push it into the collection box 8 for classification and collection. This can avoid the keyboard from shifting during the transportation process, improve the accuracy of the detection results, improve the detection effect, and improve the practicality of the device.
