[0002] The various plate parts of the keyboard base are usually fixed by riveting to improve the stability of the keyboard base. Since there are many positions on the keyboard base that need to be riveted and are affected by the angle deviation of the riveting positions, it is inevitable that the riveting positions will be missed or the riveting connectivity will be poor, resulting in the structural strength of the keyboard base being affected. Currently, the riveting connectivity of the keyboard base is usually inspected manually, which not only has low inspection efficiency but is also prone to missed inspections.

[0003] The Chinese patent with publication number CN216176348U discloses a keyboard riveting machine, including a machine body and a turntable device arranged on the machine body, a first suction and conveying device, a second suction and conveying device, a third suction and conveying device, a riveting device and a feeding device; the turntable device includes a rotating disk and a plurality of positioning jigs arranged on the edge of the rotating disk along the central circumference of the rotating disk; the first suction and conveying device, the second suction and conveying device, the third suction and conveying device, the riveting device and the feeding device are arranged on the outer periphery of the rotating disk in sequence along the clockwise rotation direction of the rotating disk; the first suction and conveying device is configured to suck and convey studs; the second suction and conveying device is configured to suck and convey keyboard workpieces; the third suction and conveying device is configured to suck and convey nuts; the riveting device is configured to perform riveting; and the feeding device is configured to output the product. The keyboard riveting machine realizes the automation of loading and unloading, detection and riveting, which can improve the utilization rate and reduce manpower input, saving costs.

[0004] However, the above device cannot detect the riveting connectivity of keyboard base plates of different models, has poor applicability, and has limitations on the detection objects. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a keyboard base plate riveting connectivity detection device to solve the above problems.

[0006] The purpose of the utility model is achieved through the following technical solutions:

[0007] The utility model provides a keyboard bottom plate riveting connectivity detection device, comprising:

[0008] The detection table has a detection port on one side of the top, and the size of the detection port is slightly smaller than the size of the keyboard bottom plate;

[0009] The clamping member is a frame body with upper and lower openings as a whole, and is used to frame the keyboard bottom plate. The clamping member can place the keyboard bottom plate above the detection port and make the riveting position of the keyboard bottom plate suspended;

[0010] A detection seat, which is located at one side of the detection table and is provided with a support plate, a telescopic cylinder is installed on the support plate, the telescopic shaft end of the telescopic cylinder faces downward and is provided with a pressing piece; and

[0011] A plurality of detection structures are provided at the bottom of the pressing member, and each of the detection structures can be located directly above the riveting position of the keyboard bottom plate.

[0012] Furthermore, a rotating column is rotatably mounted on the top of the detection table, the clamping member is mounted on the side wall of the rotating column, and a motor drivingly connected to the rotating column is mounted on the detection table.

[0013] Furthermore, at least two clamping members are disposed on the side wall of the rotating column.

[0014] Furthermore, the clamping member includes a U-shaped frame and an adapter frame, the outer wall of the U-shaped frame is connected to the side wall of the rotating column, the inner walls on both sides of the U-shaped frame are provided with sliding grooves, and the two sides of the adapter frame are provided with sliding strips adapted to the sliding grooves, and the adapter frame has multiple models with different sizes of inner walls of the frame.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0031] like Figure 1-3 As shown, a keyboard base plate riveting connectivity detection device provided in this embodiment includes a detection table 1, a clamping member 2, a detection seat 3 and a detection structure 4.

[0032] See also Figure 1 A detection port 11 is provided on one side of the top of the detection table 1 , and the size of the detection port 11 is slightly smaller than the size of the keyboard bottom plate to prevent the keyboard bottom plate from falling from the detection port 11 .

[0033] The clamping member 2 is a frame body with upper and lower openings as a whole, and is used to frame the keyboard bottom plate. The clamping member 2 can place the keyboard bottom plate above the detection port 11 and make the riveted position of the keyboard bottom plate suspended.

[0034] In one embodiment, a rotating column 12 is rotatably installed on the top of the detection table 1, and the clamping member 2 is installed on the side wall of the rotating column 12. A motor 13 driven and connected to the rotating column 12 is installed on the detection table 1. Starting the motor 13 can rotate the rotating column 12 to drive the clamping member 2 to place the keyboard base plate above the detection port 11.

[0035] Preferably, at least two clamping members 2 are provided on the side wall of the rotating column 12, such as Figure 1 As shown, when one of the clamping members 2 places the keyboard bottom plate above the detection port 11 for detection, the keyboard bottom plate can be loaded and unloaded on the other clamping members 2, thereby speeding up the detection efficiency.

[0036] In one embodiment, the clamping member 2 includes a U-shaped frame 21 and an adapter frame 22, the outer wall of the U-shaped frame 21 is connected to the side wall of the rotating column 12, the inner walls on both sides of the U-shaped frame 21 are provided with a slide groove 211, and the two sides of the adapter frame 22 are provided with a slide bar 221 adapted to the slide groove 211, and the adapter frame 22 can be detachably connected to the U-shaped frame 21 through the slide bar 221 and the slide groove 211, and the adapter frame 22 has a plurality of models with different sizes of the inner wall of the frame, and then the adapter frame 22 adapted thereto can be replaced according to the size and model of different keyboard bottom plates, thereby improving the applicability of the device. Of course, it should be noted that in order to avoid the keyboard bottom plate falling from the detection port 11 and causing the detection to fail, the board size of all keyboard bottom plates shall not be smaller than the size of the detection port 11.

[0037] See also Figure 1 and Figure 2 The detection seat 3 is located at one side of the detection table 1 and is provided with a support plate 31, on which a telescopic cylinder 32 is installed. The telescopic cylinder 32 can be a hydraulic cylinder or a pneumatic cylinder. The telescopic shaft end of the telescopic cylinder 32 faces downward and is provided with a pressing piece 33. Starting the telescopic cylinder 32 can drive the pressing piece 33 to move up and down.

[0038] Specifically, the pressing member 33 includes a connecting plate 331 and a mounting plate 332. The top of the connecting plate 331 is connected to the telescopic shaft of the telescopic cylinder 32, and the bottom is installed at intervals with the mounting plate 332 through multiple connecting rods 333. The mounting plate 332 is provided with multiple threaded holes 3321, and each threaded hole 3321 is used to correspond to the riveting position of various keyboard base plates.

[0039] See also Figure 1-Figure 3 A plurality of detection structures 4 are provided at the bottom of the pressing member 33 , and each detection structure 4 can be located directly above the riveting position of the keyboard bottom plate.

[0040] Specifically, the detection structure 4 includes a butt joint 41, the size of the butt joint 41 is larger than the inner diameter of the threaded hole 3321, and the butt joint 41 is placed above the mounting plate 332. A sleeve 42 is provided at the bottom of the butt joint 41, and an external thread is provided on the outer side of the sleeve 42. The sleeve 42 can be screwed into any threaded hole 3321. Since the size of the butt joint 41 is larger than the size of the threaded hole 3321, when the sleeve 42 and the threaded hole 3321 are screwed together until the butt joint 41 and the mounting plate 332 abut, they cannot be screwed further. This enables each detection structure 4 to have the same height position on the mounting plate 332. A pressure sensor 43 is provided at the top of the sleeve 42 and a sliding head 44 is slidably penetrated at the bottom. A spring 45 is connected between the pressure sensor 43 and the sliding head 44. The spring 45 is connected to the sensing end of the pressure sensor 43 through a gasket. When the sliding head 44 is pushed into the sleeve 42, the spring 45 will apply pressure to the pressure sensor 43. The pressure sensor 43 is externally connected to an industrial computer to transmit pressure information to the industrial computer terminal. It should be noted that when the sleeve 42 is screwed into the threaded hole 3321, the bottom end of the sleeve 42 will be located below the mounting plate 332. Among them, the industrial computer can select existing technology products sold on the market, so its specific structure will not be described in detail.

[0041] During specific use, the keyboard bottom plate frame to be tested is placed on the matching clamping member 2, and the clamping member 2 is placed above the detection port 11, so that the riveted position of the keyboard bottom plate is suspended above the detection port 11, and each detection structure 4 is installed in the threaded hole 3321 corresponding to the riveted position of the keyboard chassis on the mounting plate 332, and then the telescopic cylinder 32 is started to move the pressing member 33 downward. As the pressing member 33 moves downward, the sliding head 44 of each detection structure 4 will abut against the corresponding riveted position and apply downward pressure to the rivet. If the riveted connection of the riveted position is qualified, the sliding head 44 will be reversely abutted. Push it into the sleeve 42, and apply pressure to the pressure sensor 43 through the spring 45. The pressure sensor 43 will transmit the pressure data to the industrial computer. If the rivet is missing at the riveting position, the pressure sensor 43 cannot sense the pressure, or the riveting connectivity at the riveting position is poor, causing the sliding head 44 to push the rivet out of the riveting position, the pressure sensor 43 will also transmit the abnormal pressure data to the industrial computer. The staff can check the pressure information of the riveting position of the keyboard base plate from the industrial computer terminal, so as to judge the riveting connectivity of the keyboard base plate, which is conducive to improving the detection efficiency and accuracy, and improving the yield rate.

[0042] Preferably, a waste hopper is provided below the inspection port 11 to receive rivets that have fallen due to unqualified inspection.

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some or all of the technical features may be replaced by equivalents. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the various embodiments of the present invention, and they should all be included in the scope of the claims and specification of the present invention.
