DETAILED DESCRIPTION

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0030] like Figure 1 and Figure 2 As shown, a silicone key performance testing device includes: a base 1, a U-shaped seat 2 with an opening facing downward is fixedly arranged on the upper end surface of the base 1, and a plurality of circular holes 3 arranged equidistantly from front to back are opened on the upper end surface of the U-shaped seat 2.

[0031] A fixing unit 4 for fixing all buttons is commonly provided on the base 1 and the U-shaped base 2, and the fixing unit 4 includes a fixing column 40. Four fixing columns 40 arranged in a matrix and with vertical axes are fixedly provided on the upper end surface of the base 1. A clamping plate 41 is provided between two front and rear opposite fixing columns 40 for sliding up and down together through a mounting block, and the two clamping plates 41 are located between the left and right fixing columns 40.

[0032] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a testing mechanism 5 is provided on the base 1, and the testing mechanism 5 includes a lifting frame 50. The upper end surface of the base 1 is provided with a lifting frame 50 that slides up and down through two frame rods distributed on the left and right. The lifting frame 50 is driven by an external hydraulic cylinder to move up and down. A plurality of fan-shaped plates 500 arranged equidistantly from front to back are fixedly provided in a rectangular area of ​​the lifting frame 50. The fan-shaped plates 500 correspond to the circular holes 3 one by one. A swing bar 501 is provided on the fan-shaped plate 500. A rectangular tube 502 is fixedly provided at the lower end of the swing bar 501. A hinged bar 503 is slidably penetrated through the lower end of the rectangular tube 502 along its length direction. A pressing cap 504 is hinged at the lower end of the hinged bar 503. An inner groove is provided on the lower end surface of the pressing cap 504. The testing mechanism 5 also includes an adjusting unit 6 arranged on the lifting frame 50.

[0033] It should be noted that the adjustment unit 6 is used to adjust the distance between the lifting frame 50 and the clamping plate 41, and is also used to drive the clamping plate 41 to move downward synchronously during the downward movement of the lifting frame 50. During operation, the staff places a plurality of silicone buttons (hereinafter collectively referred to as buttons) to be tested on the upper end surface of the U-shaped seat 2, and arranges the buttons equidistantly from front to back and each button is placed above the corresponding circular hole 3. The external hydraulic cylinder works to move the lifting frame 50 downward. The downward movement of the lifting frame 50 first causes the clamping plate 41 to move downward synchronously, and the rubber around the buttons is clamped by the two clamping plates 41. The pad completes the positioning of the key, and then as the lifting frame 50 continues to move downward, the lifting frame 50 drives the pressing cap 504 to move above the corresponding key, and the key is located in the inner groove of the corresponding pressing cap 504, and the lifting frame 50 stops moving. At this time, the distance between the lifting frame 50 and the base 1 is the specified distance, and then the adjustment unit 6 works to make the hinge bar 503 move back and forth up and down, and the hinge bar 503 drives the pressing cap 504 to move back and forth up and down, and the pressing cap 504 continuously presses the corresponding key to test the durability of the key. After repeated pressing tests, observe whether the key is damaged.

[0034] The distance between the lifting frame 50 and the base 1 is adjusted by the adjustment unit 6, and the test operation is repeated to simulate pressing conditions with different pressing strengths (so that the button is pressed down by different distances), and the test operation is performed under this condition. The angle of the hinge strip 503 can also be adjusted by the adjustment unit 6, and the test process is repeated to simulate different pressure angle conditions. The above method can simulate the conditions existing in the actual use process, improve the comprehensiveness of the button test, and improve the reliability of the test data.

[0035] After completing the performance test operation of multiple keys, the external hydraulic cylinder operates to move the lifting frame 50 upward, take out the tested keys and replace them with untested keys, and repeat the test process.

[0036] like Figure 1 , Figure 2 and Figure 4 As shown, the fixing unit 4 also includes a spring 42, and a spring 42 mounted on the fixing column 40 is fixedly arranged between the base 1 and the mounting block. A lifting plate 420 is provided on the upper end surface of the base 1 through two telescopic rods which are symmetrical front and back and have vertical axes and slide up and down. A plurality of guide members 421 corresponding to the circular holes 3 are fixedly arranged on the upper end surface of the lifting plate 420 through vertical rods, and the upper end portion of the guide member 421 is divided into a frustum with a small upper portion and a large lower portion.

[0037] like Figure 1 , Figure 2 and Figure 4 As shown, the fixing unit 4 also includes a gear 43, and the opposite surfaces of the two vertical sections of the U-shaped seat 2 are rotatably provided with a transmission shaft extending from front to rear through an axis. Two racks 430 meshing with the gear 43 are slidably provided on the two vertical sections of the U-shaped seat 2, and the corresponding two racks 430 are symmetrical about the axis of the gear 43. One of the racks 430 in the same vertical section of the U-shaped seat 2 is fixedly connected to the lifting plate 420 through a connecting frame, and the other rack 430 is fixedly connected to the clamping plate 41 through a connecting frame.

[0038] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the adjusting unit 6 includes a rotating column 60, and four rotating columns 60 arranged in a matrix and with vertical axes are rotatably penetrated on the lifting frame 50. The upper end surfaces of the two clamping plates 41 are each provided with a through hole 600 located directly below the corresponding rotating column 60. The rotating column 60 is provided with a plurality of groove groups that are equidistantly distributed in a spiral from bottom to top, and the groove group includes two horizontally symmetrical support grooves 601, and the support grooves 601 in two adjacent groove groups are cross-distributed in the horizontal direction, the transverse cross-section of the support groove 601 is a right-angled triangle, and the upper end surface of the inner wall of the support groove 601 is a horizontal plane, and two left-right symmetrical sliding columns 602 are slidably penetrated on the inner wall of the through hole 600, and the opposite surfaces of the corresponding two sliding columns 602 are fixedly provided with a right-angled triangle support block 603, the opposite surfaces of the corresponding two support blocks 603 are inclined surfaces, and the upper end surfaces are both horizontal surfaces for supporting the upper horizontal surface of the support groove 601, and a spring 2 604 is fixedly provided between the support block 603 and the inner wall of the through hole 600.

[0039] During operation, the staff first places the button to be tested on the upper end surface of the U-shaped seat 2, and arranges the buttons equidistantly from front to back and each button is placed above the corresponding circular hole 3. Then the external hydraulic cylinder works to move the lifting frame 50 downward, and the lifting frame 50 drives the four rotating columns 60 thereon to move downward synchronously. After the rotating column 60 passes through the corresponding through hole 600, the support block 603 contacts the upper horizontal surface of the inner wall of the lowest support groove 601 on the corresponding rotating column 60 under the action of spring two 604, and the rotating column 60 pushes the clamping plate 41 to move downward synchronously through the support block 603, and the spring one 42 is compressed.

[0040] During the downward movement of the clamping plate 41, the clamping plate 41 drives the rack 430 thereon to move downward synchronously, and the gear 43 rotates through the meshing between the rack 430 and the corresponding gear 43, and at the same time, another rack 430 corresponding to the rack 430 drives the corresponding lifting plate 420 to move upward synchronously, and the lifting plate 420 drives the guide member 421 thereon to move upward, and the guide member 421 gradually moves upward and passes through the circular hole 3, and finally enters into the cap cavity of the key, and guides the corresponding key to move to the specified position, and finally the clamping plate 41 moves downward to limit the key downward pressure to the U-shaped seat 2, and at the same time, the upper end of the key enters the inner groove of the corresponding pressing cap 504, and in the above manner, the key is limited and fixed while moving to the bottom of the corresponding pressing cap 504, which is convenient for the subsequent testing process.

[0041] It should be noted that during this process, the support groove 601 at the lower side of the rotating column 60 cooperates with the corresponding support block 603, so after the key is pressed, the distance between the fan plate 500 and the key is the maximum value. On this basis, the actual pressing stroke of the key in subsequent tests is the minimum.

[0042] like Figure 3 As shown, two arc-shaped blocks 61 distributed front and back are fixedly provided on the inner wall of the through hole 600 .

[0043] It should be noted that the diameter of the circular cross-section formed by the cooperation of the two arc blocks 61 is adapted to the diameter of the rotating column 60. Therefore, when the rotating column 60 moves downward and passes through the corresponding through hole 600, the two arc blocks 61 cooperate with each other to limit the corresponding rotating column 60, thereby improving the stability during the downward movement process and subsequent testing processes.

[0044] like Figure 1 and Figure 2 As shown, the adjustment unit 6 also includes a sprocket 62, and a sprocket 62 located above the lifting frame 50 is fixedly sleeved on the rotating column 60. All sprockets 62 are connected by a chain, and a rotating handle 620 is fixedly provided on the upper end surface of the rotating column 60 on the left front.

[0045] During operation, after the pressing plate 41 presses the button and performs a test operation under the minimum pressing stroke, the rotating handle 620 is manually rotated to drive the corresponding rotating column 60 to rotate, and the rotating column 60 drives the sprocket 1 62 thereon to rotate synchronously, and at the same time, through the cooperation between the sprocket 1 62 and the chain 1, the remaining rotating columns 60 rotate synchronously. During the rotation of the rotating column 60, the inner wall of the lowermost support groove 601 of the rotating column 60 squeezes the corresponding support block 603, so that the support block 603 is away from the rotating column 60, the spring 2 604 is compressed, and the support block 603 gradually releases the support for the rotating column 60. When the support block 603 is staggered from the lowermost support groove 601, the elastic force generated by the deformation of the spring 1 42 causes the pressing plate 41 to rotate. It drives the support block 603 on it to move upward synchronously. It should be noted that after the rotating column 60 rotates, the second groove group from bottom to top on the rotating column 60 is opposite to the corresponding two support blocks 603, and the clamping plate 41 moves upward so that the support block 603 moves to be flush with the support groove 601 of the second groove group from bottom to top, and the elastic force generated by the deformation of the spring 2 604 makes the support block 603 fit into the support groove 601 in the groove group, and then the external hydraulic cylinder continues to work to make the clamping plate 41 move downward again. At this time, the distance between the clamping plate 41 and the lifting frame 50 is less than the distance between the two under the minimum pressing stroke state, that is, after the clamping plate 41 presses the button again, the actual pressing stroke of the pressing cap 504 increases, and then the test process is repeated.

[0046] Repeat the above operation to make the support block 603 cooperate with the support groove 601 in different groove groups on the corresponding rotating column 60, change the pressing stroke and perform the test operation. By changing the pressing stroke, the situation where the button is depressed to different degrees due to different pressing strengths is simulated, thereby improving the authenticity of the test results.

[0047] like Figure 1 , Figure 5 and Figure 6 As shown, the adjustment unit 6 includes a rotating shaft 63, and the swing bar 501 is rotatably penetrated by the rotating shaft 63 with an axis extending from front to rear. A rotating disk 630 located on the front side of the corresponding fan-shaped plate 500 is fixedly sleeved on the rotating shaft 63, and a driving bar 631 is rotatably provided on the front end surface of the rotating disk 630. A connecting groove 632 is opened on the front end surface of the rectangular tube 502, and a connecting block 633 penetrating the connecting groove 632 is fixedly provided on the upper end surface of the hinged bar 503, and the connecting block 633 is hinged to the driving bar 631.

[0048] like Figure 1 and Figure 6As shown, the adjustment unit 6 also includes a transverse frame 64, and the left end face of the swing bar 501 is fixedly provided with the transverse frame 64. A driving shaft 640 with an axis extending from front to rear rotates together on all the transverse frames 64. The driving shaft 640 is connected to an external motor, and a transmission belt is commonly provided between the driving shaft 640 and all the rotating shafts 63.

[0049] During operation, after the clamping plate 41 clamps the button, the external motor starts to work and drives the driving shaft 640 to rotate synchronously. The driving shaft 640 drives all the rotating shafts 63 to rotate synchronously through the transmission belt. The rotating shaft 63 drives the rotating disk 630 to rotate synchronously. During the full rotation of the rotating disk 630, the driving bar 631 drives the reciprocating movement up and down. During the downward movement of the driving bar 631, its lower end pushes the hinged bar 503 to move downward synchronously through the connecting block 633. The hinged bar 503 drives the corresponding pressing cap 504 to press the button, thereby completing one press of the button. The driving bar 631 moves up, driving the pressing cap 504 to move up and reset. Therefore, through the continuous rotation of the rotating disk 630, the pressing cap 504 can continuously press the button for durability performance testing.

[0050] It should be noted that, in the above process, the pressing stroke of the pressing cap 504 is the maximum downward movement distance of the driving bar 631. Before the pressing operation is performed, the upper end of the inner groove of the pressing cap 504 is located above the upper end of the key (the two are not in contact). When the subsequent adjustment unit 6 adjusts the pressing stroke, the distance between the fan plate 500 and the clamping plate 41 is changed, that is, the distance between the upper end of the inner groove of the pressing cap 504 and the upper end of the key is changed, and finally the actual pressing test stroke of the key is changed.

[0051] like Figure 1 , Figure 6 and Figure 7 As shown, the testing mechanism 5 also includes a fan-shaped groove 51, the fan-shaped plate 500 is provided with a fan-shaped groove 51 coaxial with the fan-shaped plate 500, a sliding block 510 is slidably arranged in the fan-shaped groove 51, and the sliding block 510 is fixedly connected to the corresponding swing bar 501, and the adjustment unit 6 also includes a rotating roller 65, and the rear end surface of the fan-shaped plate 500 is provided with two left-right symmetrical rotating rollers 65 through a rotating shaft, and the rotating shaft is connected to an external motor 2, and a belt 650 is provided between the two rotating rollers 65, and the fan-shaped plate 500 A stretching block for maintaining the shape of the belt 650 is fixedly provided on the rear end face thereof, an L-shaped frame 651 is fixedly provided on the outer side of the belt 650, a movable column 652 is slidably penetrated through the horizontal section of the L-shaped frame 651, a pushing bar 653 is fixedly provided on the upper end face of the movable column 652, and the pushing bar 653 is composed of a right-angled trapezoidal section and a rectangular section from top to bottom, the inclined surface of the right-angled trapezoidal section of the pushing bar 653 faces the right side and is inclined to the right from top to bottom, and a pushing column 654 located on the right side of the pushing bar 653 is fixedly provided on the rear end face of the sliding block 510.

[0052] like Figure 1 , Figure 6 and Figure 7 As shown, the adjustment unit 6 also includes a matching plate 66, and the lower end surface of the movable column 652 is fixedly provided with the matching plate 66. The matching plate 66 is composed of a horizontal section and an inclined section from left to right, and the inclined section of the matching plate 66 is inclined downward from left to right. A spring three 660 mounted on the movable column 652 is fixedly provided between the matching plate 66 and the L-shaped frame 651. Two arc plates 661 distributed on the left and right and matched with the matching plate 66 are fixedly provided on the rear end surface of the fan plate 500, and the two arc plates 661 are equidistantly distributed along the rotation direction of the belt 650. The upper arc plate 661 is taken as an example for explanation, and the inner arc surface of the arc plate 661 faces the lower side.

[0053] When performing the pressing test, the external motor 2 works to drive the rotating shaft and the rotating roller 65 to rotate synchronously, so that the belt 650 rotates counterclockwise, and the belt 650 drives the L-shaped frame 651 thereon to move synchronously. During the process of the lower section of the belt 650 moving from left to right, the L-shaped frame 651 drives the pushing bar 653 thereon to move right synchronously, and the pushing bar 653 drives the pushing column 654, and the pushing column 654 drives the sliding block 510 and the swinging bar 501 to move synchronously, and the swinging bar 501 drives the rectangular tube 502, the hinged bar 503 and the pressing cap 504 to move synchronously.

[0054] When the L-shaped frame 651 moves from the left side of the lower section of the belt 650 through the right side arc section to the right side of the upper section of the belt 650, the push bar 653 first pushes the sliding block 510 to the rightmost position of the fan-shaped groove 51. Then, as the L-shaped frame 651 continues to move, the inclined section of the matching plate 66 contacts the right side arc plate 661, and the arc plate 661 squeezes the inclined section of the matching plate 66 to make the matching plate 66 move downward. The matching plate 66 drives the moving column 652 and the push bar 653 to move downward synchronously, and the spring three 660 is stretched, and the push bar 653 moves downward. It is staggered up and down with the pushing column 654, so that the belt 650 can drive the L-shaped frame 651 and the pushing column 654 to move through the right arc section of the belt 650. After the L-shaped frame 651 moves to the right side of the pushing column 654, the pushing bar 653 is reset by the elastic force of the spring three 660. Finally, when the L-shaped frame 651 moves to the right side of the upper part of the belt 650, the pushing bar 653 is located on the right side of the pushing column 654. Therefore, in the process of the L-shaped frame 651 moving to the left along the upper part of the belt 650, the pushing bar 653 pushes the pushing column 654 to move left along the trajectory of the fan-shaped groove 51.

[0055] When the L-shaped frame 651 moves from the right side of the upper section of the belt 650 to the left side of the lower section of the belt 650 through the left arc section of the belt 650, the matching plate 66 cooperates with the arc plate 661 on the left to convert the position relationship between the push bar 653 and the push column 654, so that during the movement of the L-shaped frame 651 along the belt 650, during the pressing process, the push bar 653 pushes the sliding block 510 to move back and forth left and right through the push column 654, and the direction of application of the pressing force is adjusted by changing the direction of the hinged bar 503, thereby simulating the situation in which the button is subjected to pressing forces in different directions during actual use, and testing the durability of the button in this situation, thereby further improving the authenticity of the test results.
