The test pens... Each test pen 214 is mounted on the second sliding plate 212, and the contact end 2141 of the test pen 214 extends from the lower end of the second sliding plate 212 to contact the keyboard keys. When the positioning member 11 drives the keyboard to slide into the groove 22, the cylinder 213 drives the second sliding plate 212 to descend, causing the contact end 2141 to descend and approach the keyboard keys. Then, each test pen 214 moves up and down to strike the keys in sequence, thereby testing the elasticity of each key and whether the circuit is normal. The up and down movement of the test pen 214 can be controlled by a cylinder, hydraulic cylinder, motor, electromagnetic control, etc. This structure belongs to the prior art and will not be described in detail here. Specifically, the first sliding plate 211 can be installed on any front or rear side of the connecting frame 2, and the second sliding plate 212 is installed on the outward side of the first sliding plate. In this embodiment, the first sliding plate 211 is installed on the front side of the connecting frame 2, and the second sliding plate 212 is installed on the front side of the first sliding plate 211.

[0031] like Figures 1-3 As shown in the embodiment of this utility model, the positioning member 11 can be implemented by referring to the following technical solution for reciprocating sliding on the worktable 1: The worktable 1 is provided with a first transmission belt 133 structure for driving the positioning member 11 to translate relative to the worktable 1. The first transmission belt 133 structure includes a first driving wheel 131, a first driven wheel 132, a first transmission belt 133 and a first motor 134.

The first mounting seats 1411 have insertion holes 1412, and the ends of the first guide rod 141 are inserted into the insertion holes 1412 respectively, so that the horizontal height of the first guide rod 141 is higher than the height of the table surface of the workbench 1. When the second guide blocks 142 at the left and right ends of the lower end face of the positioning member 11 pass through the first guide rod 141 respectively, the first guide rod 141 will make the positioning member 11 higher than the table surface of the workbench 1, so as to provide movement space for the structure of the first transmission belt 133, so that the first driven wheel 132 is installed between the positioning member 11 and the workbench 1, which facilitates the first clamping part 111 to clamp the first conveyor belt. The connection method between the second guide block 142 and the positioning member 11 includes, but is not limited to, threaded connection, snap-fit ​​connection, or fixed connection.

[0033] Further as Figures 4-5 As shown in the embodiment of this utility model, the first sliding plate 211 is provided with a guide groove 2111 on one side where the second sliding plate 212 is installed, which provides a guiding function for the second sliding plate 212 when it is raised and lowered. The second sliding plate 212 is provided with a first guide block 2121 on the back side near the guide groove 2111 for insertion into the guide groove 2111.

[0034] Further as Figures 4-5 As shown in the embodiment of this utility model, a second guide rod 23 is provided on one side of the connecting frame 2 where the first sliding plate 211 is mounted. Through holes 2112 are provided on the left and right sides of the first sliding plate 211. The second guide rod 23 is inserted into the through holes 2112, allowing the first sliding plate 211 to slide on the first guide rod 141. Specifically, the connection between the two ends of the second guide rod 23 and the left and right sides of the connecting frame 2 can be achieved through interference fittings or integral molding, etc.

[0035] Further as Figures 4-5 As shown, in another embodiment of this utility model, the connecting frame 2 is provided with at least two second guide rods 23, and two through holes 2112 are opened on the left and right sides of the first sliding plate 211 respectively. The two second guide rods 23 are respectively inserted into the two through holes 2112 so that the first sliding plate 211 slides along the second guide rods 23, which can achieve a better guiding effect.

[0036] Further as Figures 4-5 As shown, in an embodiment of this utility model, the connecting frame 2 is provided with a second transmission belt 243 structure for driving the first sliding plate 211 to slide. The second transmission belt 243 structure includes a second driving wheel 241, a second driven wheel 242, a second transmission belt 243, a second motor 244, and a sliding groove 245 opened on the side of the connecting frame 2.

The second transmission belt 243 is wound around the second driving wheel 241 and the second driven wheel 242. The output end of the second motor 244 is connected to the second driving wheel 241 to drive the second driving wheel 241 to rotate. The back of the first sliding plate 211 is provided with a second clamping part 2113 for passing through the sliding groove 245 and clamping on the second transmission belt 243. When the second transmission belt 243 reciprocates, it can drive the second clamping part 2113 to move back and forth, thereby driving the first sliding plate 211 to slide left and right.

[0037] Further as Figure 1 As shown in the embodiment of this utility model, the connecting frame 2 is provided with a monitoring component 25 for monitoring the specific pressing points of the keyboard keys pressed by the test pen 214. The monitoring component 25 is installed on one side of the connecting frame 2 and located above the first sliding plate 211. Specifically, the monitoring component 25 can be a monitoring camera or a surveillance camera, which is installed on the connecting frame 2 via the second support member 15. The output end of the monitoring component 25 for recording or capturing images faces the test pen 214, and is used to record or photograph the specific pressing points of the keyboard keys pressed by the test pen 214. People can adjust the position of the test pen 214 based on the obtained images or videos to test whether the keyboard keys can respond normally when pressed at different points. For example, pressing on the edge of the keyboard key can detect the degree of response. The test pen 214 can realize the pressing action by electromagnetic drive. The test pen is a conventional technical means for those skilled in the art, and this utility model will not elaborate further.

[0038] Further as Figures 6-7As shown, in another embodiment of this utility model, a spacing adjustment mechanism for adjusting the spacing between adjacent test pens 214 is provided on the second sliding plate 212. The spacing adjustment mechanism includes an adjustment rod 31 disposed on the front end face of the second sliding plate 212, an adjustment block 34 inserted into the adjustment rod 31, and a locking block 32 for fixing both ends of the adjustment rod 31. Two first threaded through holes 33 are respectively opened on the front side of the second sliding plate 212 near the left and right ends for installing the locking block 32. The locking block 32 has a first through hole 321 for being inserted into the end of the adjustment rod 31. By setting two locking blocks 32 to be inserted into both ends of the adjustment rod 31, and then aligning the rear sides of the two locking blocks 32 with the first threaded through hole 321, the adjustment mechanism is adjusted. The threaded through hole 33 is used for threaded connection so that the adjusting rod 31 is installed on the front end face of the second sliding plate 212. The adjusting block 34 has a second through hole 345 for the adjusting rod 31 to pass through. The upper end face of the adjusting block 34 has a second threaded through hole 341. The test pen 214 is threadedly connected to the second threaded through hole 341. The front side of the adjusting block 34 has a notch 342 that connects to the second through hole 345. The upper end face of the adjusting block 34 has a third threaded through hole 346 on the side near the notch 342. The gap size of the notch 342 is adjusted by screwing a bolt and nut into the third threaded through hole 346, thereby changing the tightness of the second through hole 345.

[0039] Specifically, the spacing between adjacent test pens 214 can be adjusted through the aforementioned spacing adjustment mechanism. When encountering keyboards with different key specifications, it is necessary to adjust the spacing of the test pens 214 to achieve accurate pressing. First, loosen the bolts and nuts to enlarge the notch 342 on the adjusting block 34, causing the interference fit between the through hole and the adjusting rod 31 to change to a transition fit or clearance fit. At this time, the adjusting block 34 can slide on the adjusting rod 31, and the test pen 214 located on the adjusting block 34 changes position as the adjusting block 34 slides, thereby achieving the adjustment of the gap between the test pens 214.

[0040] Further as Figure 1 As shown in the embodiments of this utility model, each positioning member 11 is provided with a plurality of locking members 112 for locking the edge of the keyboard. The locking members 112 are detachably installed on the upper surface of the positioning member 11 and close to the edge of the positioning member 11. Specifically, locking members 112 are respectively installed on the upper surface of the positioning member 11 near the upper and lower sides, and locking members 112 are respectively installed on the upper surface of the positioning member 11 near the left and right sides. When the keyboard is placed on the upper surface of the positioning member 11, each side of the keyboard is abutted by the locking members 112 to form a locking effect. When the keyboard slides with the positioning member 11, the keyboard itself will not shift, which can reduce the positional error of the test pen 214 pressing the keyboard keys.

[0041] Further as Figure 1As shown in the embodiment of this utility model, the bottom surface of the workbench 1 is provided with at least four first support members 251 for supporting the workbench 1, and the upper end of the first support member 251 is detachably installed on the bottom surface of the workbench 1. Specifically, the bottom of the first support member is provided with anti-slip rubber or anti-slip texture.

[0042] The working principle of this utility model is as follows: By setting a detection module to adjust the pressing position of the press-type test pen 214, when the first motor 134 drives the positioning member 11 to slide, and the keyboard slides to the groove 22 with the positioning member 11, the second sliding plate 212 slides in the left and right direction with the first sliding plate 211 to adjust the adjustment of the stylus in the left and right direction. Then, the cylinder 213 drives the second sliding plate 212 to descend, so that the abutting end 2141 of the test pen 214 presses the key of the keyboard to perform a pressing test. The test pen 214 is adjustable in the horizontal position, so that the keyboard key test can be more comprehensive and the detection effect is better.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
