The pressing mechanism 110, the pressing mechanism 12A, and the button 7〇〇 are moved back and forth along the straight line L. Please refer to the 3A to 3D drawings at the same time, and the 3B to 3D diagrams show the operation process diagram of the measuring device 1 〇第 of FIG. 3A. As shown in Fig. 3b, a thrust, F110 pushes the first pusher 111 and the second pusher 112 toward the pressing mechanism I20. When the first pusher 110 abuts against the striker 121, the first pusher 111 stops moving. Lu Next, the eye refers to Figure 3C. The first pusher lu and the second pusher are relatively movable. Therefore, when the first pusher 111 abuts against the striker 121, the second pusher 112 can still move in the direction of the pressing mechanism 120. The pushing force F110 continues to push the second pushing member 112 until the thrust Fn is stopped, so that the first pushing member 111 and the second pushing member 112 move each other by a dusting distance D113. At this time, the first pushing member (1) and the second pushing member 112 compress the first elastic body 113, so that the first elastic body 113 that is dusted and contracted generates a pressing force φ. The pressing mechanism 120 pushes the striker at the pressing force f 113. 121 moves in the direction of the button 800 within a pressing stroke D121. At the same time, it is known that the key 800 is also moved by the house stroke pi21. Next, in Fig. 3D, the second elastic body 123 of the present embodiment is a spring. The second elastic body 123 is disposed between the fixing member 122 and the striker 121. While the needle 121 moves toward the button 700, the second elastic body 123 is compressed to generate a restoring force F123 on the striker 12. When the first pusher 111 and the second pusher 112 are returned upward to the source, the position is two strikers. 12丨Reverted to the original position by the return force F123. Thereby, the striker i2i 1332084 Sanda number: TW3197PA can be moved back and forth within the press stroke D121. Here, during the above motion, the pressing distance can be fine-tuned by the adjusting member 114 to cause the pressing mechanism to provide a precise pressing force f113. And when each of the pressing mechanisms m pushes the striker 2, the striker 121 moves within the fixed pressing stroke D121.

The striker 121 has a limit projection 121a and a needle-like body 121b. The fixing member 122 has a receiving groove i22a and a through hole 122 for receiving the second elastic body 123, and the through hole 122b is disposed at the bottom of the receiving groove 122a. The needle-like body penetrates through the through hole of the fixing member m, and the limit projection ma cannot pass through the mosquito member 122. That is, regardless of how much the pressing force of the pressing mechanism (10) pushes the striker 121, the limit projections 121 & limit (10) i2i move toward the button 700 within the fixed pressing stroke (1) (the pressing stroke is shown in Fig. 3C). Further, as shown in Fig. 3A, the pressing mechanism 11 further includes a pneumatic cylinder 115 and a pneumatic rod 116. Pneumatic #116 has a first end and a second end 116b. The first end l16a is movably inserted into the gas cylinder ι 5, and the second end 116b is coupled to the second urging member 112 and the adjusting member U4. The adjusting piece 114 is used to finely adjust the position of the second pushing member 112 to the pneumatic rod ιι6 to change the pressing deviation D113 (the pressing distance DU3 is shown in the 3C figure +). Wherein the second end (four) of the pneumatic rod 116 has a threaded surface 116c' and the adjustment member 114 and the second pushing member 112 are screwed to the threaded surface.

By the change of the pressing distance D113, the pressing force F113 also changes. The following is a description of the relationship between the position of the rod 116, the pressing distance D113, and the pressing force F113 by taking the 4A to 4C drawings as an example. Please refer to FIGS. 4A to 4D for an operation diagram of the test apparatus 1A of FIG. 3A finely adjusted via the adjustment element 114. As shown in Fig. 4A, when the adjustment member 114 is moved downward, the second pusher 112 is screwed down to the position of the pneumatic stalk 116 to be adjusted downward. Therefore, the second pushing member 112 and the first pushing member ^ are further away from the pneumatic cylinder 115. In other words, the first pusher 111 of the 48th view is closer to the striker 121 than the 3A diagram. Next, as shown in Fig. 4B, the first pushing member ln and the second pushing member 112 of the thrust F110 are moved in the direction of the pressing mechanism 12''. Then, as shown in Fig. 4C, when the first pusher U1 abuts against the striker 121, the second pusher 112 can still move in the direction of the pressing mechanism 丨2〇. The first pushing member 111 and the second pushing member 112 are caused to move each other by a pressing distance D213. Compared with the 3C and 4C, the pneumatic cylinders push the first pusher lu and the second pusher 112 a certain distance with an equal pushing force F110. In Fig. 4C, since the first pusher 111 is closer to the striker 121, the first pusher 111 resists the striker 121 earlier in the movement of the second pusher 121 toward the direction of the button 700.

三福號：TW3197PA 113產生一按壓力F213。其中’第一彈性體113所受到之推擠距離D1i3& D213 係與按壓力FI 13及F213正相關。也就是說，第一彈性體 111所受到之擠壓距離越大所產生之按壓力越大。相較於第4C圖及第3C圖，第4C圖之擠壓距離D213較大，因此可產生較大之按壓力F213。如上所述，即可透過調整元件 114調整第·一推動件112螺接氣動桿116之位置，進而調整擠壓距離D213及按壓力F213。接著，如第4D圖所示，當第一推動件πΐ及第二推動件112向上回復至原來位置時，撞針121藉由回復力 F123回復至原來位置。如上所述，使用者如欲增加按壓力F113，則可將調整元件114向下調整。反之，若欲減少按壓力F113則可將調整元件114向上調整。並透過一推力計量測出精確的按壓力F113，即可精準地控制按壓力F113之大小。其中’第一彈性體113之彈性係數遠大於第二彈性體 123之彈性係數，使得第一彈性體113所產生之按壓力 F113或F213足以抵銷第二彈性體123所產生之回復力 F123。苇二實施例本實施例之測試襄置200與第一實施例之夠試事置 100不同之處在於施壓機構110、按壓機構120之敦量其餘相同之處不再贅述。請參照第5圖，其繪示依两本為 12 1332084Sanfu: TW3197PA 113 produces a pressing force F213. The pushing distance D1i3& D213 to which the first elastic body 113 is subjected is positively correlated with the pressing forces FI 13 and F213. That is, the pressing force generated by the first elastic body 111 is increased as the pressing force is increased. Compared with Figs. 4C and 3C, the pressing distance D213 of Fig. 4C is large, so that a large pressing force F213 can be generated. As described above, the position of the first pusher 112 screwing the pneumatic rod 116 can be adjusted through the adjusting member 114, thereby adjusting the pressing distance D213 and the pressing force F213. Next, as shown in Fig. 4D, when the first pusher π ΐ and the second pusher 112 are returned upward to the original position, the striker 121 is returned to the original position by the restoring force F123. As described above, if the user wants to increase the pressing force F113, the adjusting member 114 can be adjusted downward. Conversely, if the pressing force F113 is to be reduced, the adjusting member 114 can be adjusted upward. And by measuring the precise pressing force F113 through a thrust measurement, the pressing force F113 can be precisely controlled. The elastic modulus of the first elastic body 113 is much larger than the elastic modulus of the second elastic body 123, so that the pressing force F113 or F213 generated by the first elastic body 113 is sufficient to offset the restoring force F123 generated by the second elastic body 123. Second Embodiment The test device 200 of the present embodiment is different from the test device 100 of the first embodiment in that the pressing mechanism 110 and the pressing mechanism 120 are the same and will not be described again.

Each pressure applying mechanism 110 and each pressing mechanism 120 correspond to each other to test the reliability or life of a plurality of buttons 600, respectively. The pressure applying mechanism 丨1〇 and the pressing mechanism 120 are arranged in an in-line manner. As long as the lengths of the strikers 121 of the respective pressing mechanisms 120 are equal, the respective striker pins 121 are restricted by the fixing members 22 so that the respective strikers 121 are moved within the same pressing stroke D121. Therefore, the test performed by each button will be more accurate. Further, even if the thrust force FU of each of the pneumatic cylinders 115 has a certain degree of error, the user only needs to adjust the pressing distance D113 by each of the adjusting members 114 to obtain an equal pressing force FU3.
