Description

Technical Field

[0001] The present invention relates to the technical field of silicone key life test, and in particular to a silicone key life tester and a use method thereof. Background Art

[0002] As the name suggests, silicone keys are key products made of silicone as raw material. Silicone keys are a product category of silicone products. Since silicone rubber is a highly active adsorption material, it is an amorphous substance, insoluble in water and any solvent, non-toxic and odorless, with stable chemical properties, and does not react with any substance except strong alkali and hydrofluoric acid. Various types of silicone form different microporous structures due to their different manufacturing methods, which makes silicone keys have excellent heat resistance, cold resistance, environmental resistance, electrical insulation, fatigue resistance and other characteristics.

[0003] During the production process of silicone keys, the service life needs to be tested. The silicone key life tester usually simulates the actual use of the keys and repeatedly presses the keys at a certain frequency and force. Its core components include driving devices, pressing mechanisms and counting devices.

[0004] However, when testing silicone keys, the life of silicone keys is measured only by limited indicators such as the number of presses, which cannot fully represent the complex situations in actual use, such as the combined impact of different forces and environments on the keys. Secondly, during the silicone key testing process, when testing different positions of the silicone keys, the silicone keys need to be removed and re-fixed, which will consume too much time. Based on the above problems, the present application proposes a silicone key life tester and a method of use. Summary of the invention

[0015] A method for using a silicone key life tester comprises the following steps:

[0016] Step 1: Place the silicone key to be tested on the top of the moving plate, turn the threaded knob so that the threaded knob pushes the clamping plate downward, and guide the moving direction of the clamping plate through the guide rod so that the clamping plate contacts the edge of the silicone key to fix the position of the silicone key;

[0017] Step 2: When the silicone button position is fixed, the servo motor drives the output end to drive the installation shell to rotate, and the installation shell drives the pawl to move through the fixing pin, so that the pawl is inserted into the groove of the ratchet, so that the ratchet drives the reciprocating screw to rotate, and the reciprocating screw sleeve moves on the surface of the reciprocating screw, and the moving direction of the reciprocating screw sleeve is limited and guided by the sliding sleeve and the sliding rail, so that the U-shaped mounting plate drives the electric push rod to move, so that the electric push rod drives the mounting rod to move to the test position of the silicone button through the mounting sleeve, and the output end is driven downward by the electric push rod, so that the mounting sleeve drives the mounting rod to press the silicone button, and when the mounting rod presses the silicone button, the mounting rod applies pressure to the detection end of the pressure sensor, and the pressure applied by the mounting rod to the silicone button can be controlled through the pressure sensor detection, and the number of times the mounting rod presses the silicone button can be recorded;

[0018] Step 3: When the servo motor drives the output end to rotate, the active transmission wheel drives the driven transmission wheel to rotate through the transmission belt, and drives the rotating shaft to rotate inside the U-shaped fixed plate through the driven transmission wheel. If the rotating shaft rotates forward, the rotating shaft drives the second ratchet to rotate, so that the second pawl flips on the surface of the second fixed pin and compresses the second spring. If the rotating shaft rotates in the opposite direction, the second ratchet pushes the second pawl to move, and the second pawl drives the second spring to rotate through the second fixed pin, and drives the connecting shaft to rotate inside the U-shaped fixed plate through the second spring, so that the active bevel gear drives the second reciprocating screw to rotate through the active bevel gear, so that the reciprocating screw sleeve 2 drives the moving plate to move back and forth, thereby adjusting the position of the silicone button;

[0019] Step 4: However, when monitoring the silicone keys in a high temperature or high humidity environment, the external air is drawn into the fan through the fan, and enters the test box after being heated by the heating rod, thereby forming a high temperature environment inside the test box. The water flows into the connecting shaft through the external conveying equipment, and is sprayed out through the atomizing nozzle and blown into the test box by the fan, so that a high humidity environment is formed inside the test box. If the atomized water flow is blown into the test box by heated air, a high temperature and high humidity environment is formed inside the test box, thereby simulating the use environment of the silicone keys.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The silicone key life tester and its use method drive the reciprocating screw rod 1 to rotate through the connecting component 1 by the servo motor, so that the reciprocating screw sleeve 1 drives the pressing group to move to the silicone key test position through the U-shaped mounting plate, and at the same time, the transmission component drives the rotating shaft to rotate, wherein the rotating shaft cannot drive the connecting shaft to rotate through the connecting component 2 when the rotating shaft rotates forward, and the reciprocating screw rod 1 can rotate normally at this time. If the rotating shaft drives the connecting shaft to rotate through the connecting component 2, the reciprocating screw rod 1 does not rotate at this time, and the active bevel gear drives the reciprocating screw rod 2 to rotate through the driven bevel gear, so that the reciprocating screw sleeve 2 drives the silicone key to move through the fixing component, thereby facilitating the adjustment of the test position of the silicone key, avoiding the need to remove and re-fix the silicone key for testing at different positions, thereby making the silicone key tester more flexible to use.

[0022] 2. The silicone key life tester and its use method heat and humidify the air entering the test box through the heating and humidification component, which can make the inside of the test box present a high temperature environment, a high humidity environment, and a high temperature and high humidity environment, thereby simulating the use environment of the silicone key, so that the test result of the silicone key is more accurate.

[0023] 3. The silicone key life tester and its use method can fix the position of the silicone key through a fixing component, thereby avoiding deviation of the silicone key during the detection process, which causes deviation in the pressed position. The fixing component and the pressing component cooperate to accurately press the silicone key test position. BRIEF DESCRIPTION OF THE DRAWINGS

If the rotating shaft 10 rotates forward, the rotating shaft 10 drives the ratchet wheel 235 to rotate, so that the ratchet pawl 236 turns over on the surface of the fixed pin 237 and compresses the spring 238. At this time, the servo motor 4 drives the output end to drive the mounting housing 127 to rotate, and the mounting housing 127 drives the ratchet pawl 24 to move through the fixed pin 125, so that the ratchet pawl 24 is inserted into the groove of the ratchet wheel 23, so that the ratchet wheel 23 3 drives the reciprocating screw 1 5 to rotate. If the rotating shaft 10 rotates in the opposite direction, the ratchet 2 35 pushes the pawl 2 36 to move. The pawl 2 36 drives the spring 2 38 to rotate through the fixing pin 2 37, and drives the connecting shaft 13 to rotate inside the U-shaped fixing plate 11 through the spring 2 38, so that the active bevel gear 14 drives the reciprocating screw 2 16 to rotate through the active bevel gear 14, so that the reciprocating screw sleeve 2 17 drives the moving plate 18 to move forward and backward, thereby adjusting the position of the silicone key, so that the test position of the silicone key can be adjusted, and through the forward or reverse rotation of a servo motor 4.

[0037] Specifically, the guide assembly includes a sliding sleeve 7 on the top of the reciprocating screw sleeve 6, a sliding rail 8 is slidably arranged inside the sliding sleeve 7, and the sliding rail 8 is fixedly installed on the upper side wall of the test box 1. The reciprocating screw sleeve 6 drives the sliding sleeve 7 to move on the surface of the sliding rail 8, thereby limiting and guiding the moving direction of the reciprocating screw sleeve 6.

[0038] Specifically, the pressing assembly includes an electric push rod 31 fixedly installed inside the U-shaped mounting plate 9, and a mounting sleeve 32 is fixedly provided at the output end of the electric push rod 31, and a mounting rod 33 is slidably provided inside the mounting sleeve 32. A pressure sensor 34 is overlapped on the top of the mounting rod 33, and the pressure sensor 34 is fixedly installed inside the mounting sleeve 32. The output end is driven downward by the electric push rod 31, so that the mounting sleeve 32 drives the mounting rod 33 to press the silicone button, and when the mounting rod 33 presses the silicone button, the mounting rod 33 applies pressure to the detection end of the pressure sensor 34. Through the detection of the pressure sensor 34, the pressure applied by the mounting rod 33 to the silicone button can be controlled, and the number of times the mounting rod 33 presses the silicone button can be recorded, so that the service life of the silicone button under different pressures can be detected.

[0039] Specifically, the fixing component includes an L-shaped mounting plate 19 fixedly mounted on the top of the movable plate 18, a threaded knob 20 is provided on the internal thread of the L-shaped mounting plate 19, a clamping plate 21 is rotatably provided on the bottom end of the threaded knob 20, a guide rod 22 is fixedly provided on the top of the clamping plate 21, and the guide rod 22 is slidably provided inside the L-shaped mounting plate 19. The threaded knob 20 is rotated so that the clamping plate 21 fixes the silicone button, thereby avoiding deviation in the position of the silicone button during the detection process, which causes errors in the detection results.

[0040] A method for using a silicone key life tester comprises the following steps:

[0041] Step 1: Place the silicone key to be tested on the top of the moving plate 18, turn the threaded knob 20, so that the threaded knob 20 pushes the clamping plate 21 to move downward, and guide the moving direction of the clamping plate 21 through the guide rod 22, so that the clamping plate 21 contacts the edge of the silicone key, and the position of the silicone key is fixed;

[0042] Step 2: After the silicone button position is fixed, the servo motor 4 drives the output end to drive the mounting housing 27 to rotate, and the mounting housing 27 drives the pawl 24 to move through the fixing pin 25, so that the pawl 24 is inserted into the groove of the ratchet 23, so that the ratchet 23 drives the reciprocating screw 5 to rotate, and the reciprocating screw sleeve 6 moves on the surface of the reciprocating screw 5, and the moving direction of the reciprocating screw sleeve 6 is limited and guided by the sliding sleeve 7 and the sliding rail 8, so that the U-shaped mounting plate 9 drives the electric push rod 31 to move , so that the electric push rod 31 drives the installation rod 33 to move to the test position of the silicone key through the installation sleeve 32, and the output end is driven downward by the electric push rod 31, so that the installation sleeve 32 drives the installation rod 33 to press the silicone key, and when the installation rod 33 presses the silicone key, the installation rod 33 will apply pressure to the detection end of the pressure sensor 34. Through the detection of the pressure sensor 34, the pressure applied by the installation rod 33 to the silicone key can be controlled, and the number of times the installation rod 33 presses the silicone key can be recorded;

[0043] Step 3: When the servo motor 4 drives the output end to rotate, the active transmission wheel 28 drives the driven transmission wheel 30 to rotate through the transmission belt 29, and drives the rotating shaft 10 to rotate inside the U-shaped fixed plate 11 through the driven transmission wheel 30. If the rotating shaft 10 rotates forward, the rotating shaft 10 drives the ratchet wheel 2 35 to rotate, so that the ratchet pawl 2 36 turns over on the surface of the fixed pin 2 37 and compresses the spring 2 38. If the rotating shaft 10 rotates in the opposite direction, the ratchet wheel 2 35 pushes the ratchet pawl 2 36 to move, and the ratchet pawl 2 36 drives the spring 2 38 to rotate through the fixed pin 2 37, and drives the connecting shaft 13 to rotate inside the U-shaped fixed plate 11 through the spring 2 38, so that the active bevel gear 14 drives the reciprocating screw 2 16 to rotate through the active bevel gear 14, so that the reciprocating screw sleeve 2 17 drives the moving plate 18 to move back and forth, thereby adjusting the position of the silicone button;

[0044] Step 4: However, when monitoring the silicone keys in a high temperature or high humidity environment, external air is drawn into the fan 41 through the fan 41, and is heated by the heating rod 42 before entering the test box 1, thereby forming a high temperature environment inside the test box 1. Water flows through an external conveying device into the connecting shaft 13, and is atomized and sprayed out through the atomizing nozzle 12, and is blown into the test box 1 by the fan 41, thereby forming a high humidity environment inside the test box 1. If the atomized water flow is blown into the test box 1 by heated air, a high temperature and high humidity environment is formed inside the test box 1, thereby simulating the use environment of the silicone keys.

[0045] When in use: place the silicone key to be tested on the top of the moving plate 18, turn the threaded knob 20, so that the threaded knob 20 pushes the clamping plate 21 to move downward, and guide the moving direction of the clamping plate 21 through the guide rod 22, so that the clamping plate 21 contacts the edge of the silicone key to fix the position of the silicone key. When the silicone key position is fixed, the servo motor 4 drives the output end to drive the mounting shell 27 to rotate, and the mounting shell 27 drives the pawl 24 to move through the fixing pin 25, so that the pawl 24 is inserted into the groove of the ratchet 23, so that the ratchet 23 drives the reciprocating screw 5 to rotate, and the reciprocating screw sleeve 6 moves on the surface of the reciprocating screw 5, and through The sliding sleeve 7 and the sliding rail 8 limit and guide the moving direction of the reciprocating screw sleeve 6, so that the U-shaped mounting plate 9 drives the electric push rod 31 to move, so that the electric push rod 31 drives the mounting rod 33 to move to the test position of the silicone button through the mounting sleeve 32, and the output end is driven downward by the electric push rod 31, so that the mounting sleeve 32 drives the mounting rod 33 to press the silicone button, and when the mounting rod 33 presses the silicone button, the mounting rod 33 applies pressure to the detection end of the pressure sensor 34. Through the detection of the pressure sensor 34, the pressure applied by the mounting rod 33 to the silicone button can be controlled, and the number of times the mounting rod 33 presses the silicone button can be recorded. When the servo motor 4 drives the output end to rotate, The active transmission wheel 28 drives the driven transmission wheel 30 to rotate through the transmission belt 29, and drives the rotating shaft 10 to rotate inside the U-shaped fixed plate 11 through the driven transmission wheel 30. If the rotating shaft 10 rotates forward, the rotating shaft 10 drives the ratchet wheel 35 to rotate, so that the ratchet pawl 36 turns over on the surface of the fixed pin 37 and compresses the spring 38. If the rotating shaft 10 rotates in the opposite direction, the ratchet wheel 35 pushes the ratchet pawl 36 to move, and the ratchet pawl 36 drives the spring 38 to rotate through the fixed pin 37, and drives the connecting shaft 13 to rotate inside the U-shaped fixed plate 11 through the spring 38, so that the active bevel gear 14 drives the reciprocating screw 16 to rotate through the active bevel gear 14, thereby making the reciprocating screw sleeve 1 7 drives the movable plate 18 to move forward and backward, thereby adjusting the position of the silicone key. However, in a high temperature or high humidity environment, when the silicone key is tested, the external air is sucked into the fan 41 through the fan 41, and enters the test box 1 after being heated by the heating rod 42, so that a high temperature environment is formed inside the test box 1. The water flows into the connecting shaft 13 through the external conveying equipment, and is sprayed out through the atomizing nozzle 12, and is blown into the test box 1 by the fan 41, so that a high humidity environment is formed inside the test box 1. If the atomized water flow is blown into the test box 1 by the heated air, a high temperature and high humidity environment is formed inside the test box 1, so that the use environment of the silicone key can be simulated.

9. A method for using a silicone key life tester according to any one of claims 1 to 8, characterized in that: The following steps are involved: Step 1: Place the silicone key to be tested on the top of the moving plate (18), turn the threaded knob (20), so that the threaded knob (20) pushes the clamping plate (21) to move downward, and guide the moving direction of the clamping plate (21) through the guide rod (22), so that the clamping plate (21) contacts the edge of the silicone key, and the position of the silicone key is fixed; Step 2: After the silicone button is fixed in position, the servo motor (4) drives the output end to drive the mounting housing (27) to rotate, and the mounting housing (27) drives the ratchet (24) to move through the fixing pin (25), so that the ratchet (24) is inserted into the groove of the ratchet (23), so that the ratchet (23) drives the reciprocating screw (5) to rotate, and the reciprocating screw sleeve (6) moves on the surface of the reciprocating screw (5), and the moving direction of the reciprocating screw sleeve (6) is limited and guided by the sliding sleeve (7) and the sliding rail (8), so that the U-shaped mounting plate (9) drives the electric push rod (31) The electric push rod (31) drives the mounting rod (33) to move to the testing position of the silicone key through the mounting sleeve (32), and the output end is driven downward by the electric push rod (31), so that the mounting sleeve (32) drives the mounting rod (33) to press the silicone key. When the mounting rod (33) presses the silicone key, the mounting rod (33) applies pressure to the detection end of the pressure sensor (34). The pressure applied by the mounting rod (33) to the silicone key can be controlled through detection by the pressure sensor (34), and the number of times the mounting rod (33) presses the silicone key can be recorded. Step 3: When the servo motor (4) drives the output end to rotate, the active transmission wheel (28) drives the driven transmission wheel (30) to rotate through the transmission belt (29), and the driven transmission wheel (30) drives the rotating shaft (10) to rotate inside the U-shaped fixed plate (11). If the rotating shaft (10) rotates forward, the rotating shaft (10) drives the second ratchet wheel (35) to rotate, so that the second ratchet pawl (36) turns over on the surface of the second fixed pin (37) and compresses the second spring (38). If the rotating shaft (10) rotates forward, the second ratchet wheel (35) rotates forward, so that the second ratchet pawl (36) turns over on the surface of the second fixed pin (37) and compresses the second spring (38). When the gear is rotated in the reverse direction, the second ratchet wheel (35) pushes the second ratchet pawl (36) to move, and the second ratchet pawl (36) drives the second spring (38) to rotate through the second fixing pin (37), and drives the connecting shaft (13) to rotate inside the U-shaped fixing plate (11) through the second spring (38), so that the active bevel gear (14) drives the second reciprocating screw (16) to rotate through the active bevel gear (14), so that the second reciprocating screw sleeve (17) drives the moving plate (18) to move forward and backward, thereby adjusting the position of the silicone key; Step 4: However, when monitoring the silicone keypad in a high temperature or high humidity environment, external air is drawn into the fan (41) through the fan (41), and is heated by the heating rod (42) and then enters the test box (1), thereby forming a high temperature environment inside the test box (1). Water flows through an external conveying device into the connecting shaft (13), and is atomized and sprayed out through the atomizing nozzle (12), and is blown into the test box (1) by the fan (41), thereby forming a high humidity environment inside the test box (1). If the atomized water flow is blown into the test box (1) by heated air, a high temperature and high humidity environment is formed inside the test box (1), thereby simulating the use environment of the silicone keypad.
