[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Please see Figure 1-5 This utility model provides the following technical solution: a multi-station key impact life testing machine, including a base 1, a support leg 8 at the lower corner of the base 1, a support rod 4 at the upper corner of the base 1, a top plate 5 at the upper end of the support rod 4, three sets of electric push rods 6 at the upper end of the top plate 5, a test chamber 3 at the output end of the electric push rods 6, a central rod 12 running through the interior of the test chamber 3, a pressure plate 13 at the lower end of the central rod 12, an impact block 14 at the lower end of the pressure plate 13, a baffle 10 at the upper end of the central rod 12, a return spring 11 sleeved on the surface of the central rod 12 at the lower end of the baffle 10, a motor 16 on the side of the test chamber 3, a drive shaft 15 at the output end of the motor 16, a cam 9 at the other end of the drive shaft 15, a keyboard sorting mechanism 2 inside the base 1, and a keyboard positioning mechanism 7 inside the upper end of the base 1.

[0023] Specifically, the keyboard positioning mechanism 7 includes a second transmission component 71, a second motor 72, a nut block 73, a U-shaped positioning plate 74, a first bidirectional lead screw 75, a rubber pad 76, a first transmission component 77, a second bidirectional lead screw 78, and a third bidirectional lead screw 79. The second motor 72 is located at the side corner of the base 1. The output end of the second motor 72 is equipped with a first bidirectional lead screw 75. The other end of the first bidirectional lead screw 75 is equipped with a first transmission component 77. The other side of the first transmission component 77, located inside the base 1, is equipped with a second bidirectional lead screw 78. The other end of the second bidirectional lead screw 78 is equipped with a second transmission component 71. The other side of the second transmission component 71, located inside the base 1, is equipped with a third bidirectional lead screw 79. Two sets of nut blocks 73 are symmetrically arranged on the surfaces of the first bidirectional lead screw 75, the second bidirectional lead screw 78, and the third bidirectional lead screw 79. A U-shaped positioning plate 74 is located at the upper end of each nut block 73, and a rubber pad 76 is located on the side of the U-shaped positioning plate 74.

[0024] By adopting the above technical solution, the keyboard positioning mechanism 7 can accurately fix the keyboard and ensure the stability of the keyboard during the test. The motor 2 72 drives the bidirectional lead screw 1 75 to rotate, and through the transmission component 1 77 and the transmission component 2 71, it drives the bidirectional lead screw 2 78 and the bidirectional lead screw 3 79 to rotate synchronously, so that the nut block 73 moves along the bidirectional lead screw, thereby adjusting the position of the U-shaped positioning plate 74 to adapt to keyboards of different sizes. The rubber pad 76 can effectively protect the keyboard surface and prevent damage during the fixing process.

[0025] Specifically, the transmission assembly 77 includes a mounting box 771, a timing pulley 772, a timing belt 773, and a timing pulley 774. The mounting box 771 is located at one edge of the base 1. One end of the double-acting lead screw 75 is located inside the mounting box 771 and the timing pulley 772 is located therein. One end of the double-acting lead screw 78 is located inside the mounting box 771 and the timing pulley 774 is located therein. The timing belt 773 is meshed with the outer surfaces of the timing pulleys 772 and 774.

[0026] By adopting the above technical solution, the transmission component 77 realizes the synchronous transmission between the bidirectional lead screw 75 and the bidirectional lead screw 78. The synchronous pulley 772 and the synchronous pulley 774 are connected by the synchronous belt 773, which ensures the synchronous rotation of the bidirectional lead screw, thereby ensuring the accuracy and stability of the keyboard positioning.

[0027] Specifically, transmission assembly 2 71 includes synchronous pulley 4 711, mounting box 2 712, synchronous belt 2 713, and synchronous pulley 3 714. Mounting box 2 712 is located on the other edge of base 1. Synchronous pulley 3 714 is located inside mounting box 2 712 on one end surface of bidirectional lead screw 2 78. Synchronous pulley 4 711 is located inside mounting box 2 712 on one end surface of bidirectional lead screw 3 79. Synchronous belt 2 713 is meshed with the outer surfaces of synchronous pulley 4 711 and synchronous pulley 3 714.

[0028] By adopting the above technical solution, transmission component 2 71 realizes synchronous transmission between bidirectional lead screw 2 78 and bidirectional lead screw 3 79. Synchronous pulley 3 714 and synchronous pulley 4 711 are connected by synchronous belt 2 713, which further ensures the synchronous rotation of the bidirectional lead screw and improves the accuracy and reliability of keyboard positioning.

[0029] In this embodiment, the keyboard to be tested is first placed in the keyboard positioning mechanism 7 on the upper end of the base 1. The second motor 72 is started. The second motor 72 drives the second and third double lead screws 78 and 79 to rotate through the first double lead screw 75, the first transmission component 77 and the second transmission component 71. This causes the nut block 73 to move along the double lead screws, thereby adjusting the position of the U-shaped positioning plate 74 and firmly fixing the keyboard on the rubber pad 76. Then, the electric push rod 6 is started. The electric push rod 6 pushes the test box 3 down, so that the striking block 14 contacts the keyboard keys. The first motor 16 drives the cam 9 to rotate through the drive shaft 15. The cam 9 performs periodic striking tests on the keyboard keys through the pressure plate 13 on the center rod 12 and the striking block 14. The return spring 11 provides a return force after each strike, ensuring that the striking block 14 can accurately return to the initial position. In this way, multi-station simultaneous testing of the keyboard is achieved, improving testing efficiency and accuracy.

[0030] Example 2

[0031] The difference between this embodiment and Embodiment 1 is that the keyboard sorting mechanism 2 includes a slot 21, a base 22, a fixing component 23, a block 24, a fixing hole 25, a connecting plate 26, bolts 27, a sorting box 28, a partition 29, and a handle 210. The sorting box 28 is slidably connected inside the base 1. A partition 29 is provided inside the sorting box 28. A handle 210 is provided at the upper side of the sorting box 28. A connecting plate 26 is provided at the side edge of the sorting box 28. The connecting plate 26 and the sorting box 28 are fixedly connected by bolts 27. A block 24 is provided on the side of the connecting plate 26, and a fixing hole 25 is provided at the upper end of the block 24. A base 22 is provided at the side edge of the base 1, and a slot 21 corresponding to the block 24 is provided on the side of the base 22. A fixing component 23 is provided inside the side of the base 22.

[0032] By adopting the above technical solution, the keyboard sorting mechanism 2 can sort and store the keyboards that have completed testing. The partition 29 inside the sorting box 28 divides the keyboards into two areas: qualified products and unqualified products, which facilitates subsequent management and processing. The design of the card block 24 and the card seat 22 allows the sorting box 28 to be firmly fixed inside the base 1, ensuring the stability of the sorting process.

[0033] Specifically, the fixing component 23 includes an adjustment groove 231, an adjustment block 232, a fixing rod 233, and a compression spring 234. The compression spring 234 is located inside the side of the card holder 22, and the other end of the compression spring 234 is equipped with a fixing rod 233. The adjustment block 232 is located on the side of the fixing rod 233, and the side of the card holder 22 has an adjustment groove 231 corresponding to the adjustment block 232.

[0034] By adopting the above technical solution, the fixing component 23 can ensure the stable fixing of the card block 24 in the card seat 22, the compression spring 234 provides elastic force so that the fixing rod 233 can firmly lock the card block 24, and the design of the adjusting block 232 and the adjusting groove 231 allows the position of the fixing rod 233 to be finely adjusted as needed, further improving the fixing effect and reliability of the sorting box 28.

[0035] In this embodiment, the sorting box 28 is fixed inside the base 1 by the card block 24 and the card seat 22. The keyboards that have completed the test are sorted and placed in the qualified or unqualified product area inside the sorting box 28 according to the test results. The sorting box 28 can be easily removed from the base 1 by the handle 210 for subsequent processing. This design not only improves the efficiency of testing, but also facilitates the management and analysis of test results, ensuring quality control in the production process.

[0036] The working principle and usage process of this utility model are as follows: When using this utility model, firstly, the keyboard to be tested is placed in the keyboard positioning mechanism 7 on the upper end of the base 1. Then, motor 2 72 is started. Motor 2 72 drives bidirectional lead screws 2 78 and 3 79 to rotate via bidirectional lead screw 1 75, transmission assembly 1 77, and transmission assembly 2 71, causing the nut block 73 to move along the bidirectional lead screws, thereby adjusting the position of the U-shaped positioning plate 74 and firmly fixing the keyboard onto the rubber pad 76. Next, electric push rod 6 is started. Electric push rod 6 pushes the test box 3 down, causing the striking block 14 to contact the keyboard keys. Motor 1 16 drives cam 9 to rotate via drive shaft 15. Cam 9 rotates via pressure plate 13 on the central rod 12. The keycaps are periodically struck by the striking block 14, and the return spring 11 provides a restoring force after each strike to ensure that the striking block 14 can accurately return to its initial position. In this way, multiple stations of the keyboard can be tested simultaneously, improving testing efficiency and accuracy. The sorting box 28 is fixed inside the base 1 by the locking block 24 and the locking seat 22. The keyboards that have completed the test are sorted and placed in the qualified or unqualified areas inside the sorting box 28 according to the test results. The sorting box 28 can be easily removed from the base 1 by the handle 210 for subsequent processing. This design not only improves the testing efficiency, but also facilitates the management and analysis of test results, ensuring quality control in the production process.
