[0003] According to a Chinese patent with application publication number CN118330524A, a solenoid valve electromagnetic force testing device and a testing method thereof are disclosed. By setting a test component, the sensor component is compensated by using a combination of binary iteration method and progressive method, and the zero point position of the electromagnet of the solenoid valve is accurately found to improve the measurement accuracy. The hydraulic pressure is always in a state of dynamic equilibrium through the pressure control component, and the continuously changing electromagnetic force value is detected at the current value of different solenoid valves.

[0015] The testing method of the durability testing device of the solenoid valve comprises the following steps:

[0016] S1, the output shaft of the reduction motor drives the connected conveyor shaft roller to rotate, and with the cooperation of another set of conveyor shaft rollers, the conveyor belt drives the left and right limit strips to rotate around the two conveyor shaft rollers. During this period, the inspector places the solenoid valve from the right end of the conveying component on the top of the conveyor belt, and makes the solenoid valve located between the left and right limit strips. The subsequent solenoid valves added to the top of the conveyor belt are placed in this way, and the subsequent placement of a solenoid valve must always be separated from the previous solenoid valve by two left and right limit strips.

[0017] S2, during the rotation of the conveyor belt, the solenoid valve placed on the top of it is continuously transported to the left. During the transportation of the solenoid valve, the support of multiple support rollers on the conveyor belt can ensure that the conveyor belt does not sag, and the conveyor belt will also drive the driven roller during the rotation. The rotation of the driven roller drives the active bevel gear to rotate through the driven shaft. The rotation of the active bevel gear drives the twisted vertical shaft to rotate inside the two twisted brackets through the driven bevel gear. The rotation of the twisted vertical shaft drives the detection circular shell to rotate. When the conveyor belt transports one of the solenoid valves to the position between the front and rear two detection components, the arc groove opened at the end of one of the pole sliders of the two front and rear detection components is just stuck on the outer walls of the two poles of the solenoid valve. When the two arc grooves are stuck After the two poles of the electromagnetic valve are on the outer wall, as the conveyor belt continues to transport the electromagnetic valve to move to the left, the two detection circular shells continue to rotate synchronously, driving the pole slide bar to rotate together. Since the pole slide bar is affected by the abutment of the arc groove and the electromagnetic valve pole, during the rotation of the detection circular shell, a pole slide bar abutting against the electromagnetic valve pole is affected by the reverse force of the electromagnetic valve pole, pushing the pole slide bar to move along the first slide groove toward the center block, causing the V-shaped spring to be compressed and stored. Among them, when the pole slide bar moves, it will also drive the buffer slide bar to move along the inner wall of the second slide groove, causing the insulating roller to gradually move toward the top of the buffer slide bar under the wedge force of the guide slope, thereby lifting the insulating roller upward. This causes the end of the detection strip close to the insulating roller to lift up, and further under the hinged action of the hinged seat and the detection strip, the end of the detection strip close to the arc-shaped groove moves downward, and the second spring is compressed, thereby abutting against the top of the pole of the solenoid valve. At this time, the insulating roller is still on the surface of the guide slope and has not reached the top of the buffer slide bar. As the pole of the solenoid valve continues to push the pole slide bar to move together with the buffer slide bar, since the detection strip abuts against the top of the solenoid valve pole, that is, the detection strip will not continue to flip over, the insulating roller will not continue to move upward, which makes the wedge force of the insulating roller and the guide slope cause the buffer slide bar to slide downward along the inner wall of the buffer slide groove, and multiple first springs are compressed and stored until the insulating roller moves. After reaching the top of the buffer slide bar, the displacement of the buffer slide bar moving downward reaches the maximum, that is, the first spring will not continue to be compressed. When the two detection pressure strips at the front and rear are simultaneously in contact with the tops of the two poles of the solenoid valve, the detection circuit is turned on, the detection of the solenoid valve is realized, and the detection signal is transmitted to the inside of the corresponding detection module, and then transmitted by the detection module to the external computer, and the data is displayed on the computer display screen to judge whether the solenoid valve is qualified or not. During this period, the solenoid valve is still being transported under the rotation of the conveyor belt. During this period, the movement of the driven shaft will cause compression to the compressed airbag. The air inside the compressed airbag is compressed and enters the inside of the annular airbag through the air guide tube, causing the deflated annular airbag to expand and clamp the front and rear solenoid valve;

[0018] S3, when the solenoid valve being tested is conveyed to the middle of the two detection circular shells located in the front and rear, the displacement of the two pole sliders abutting against the pole of the solenoid valve reaches the maximum value, that is, the compression of the V-shaped spring reaches the maximum, and with the continued rotation of the detection circular shell and the continued rotation of the conveyor belt, the solenoid valve continues to be conveyed to the left, after which the rebound force of the V-shaped spring is gradually released, pushing the pole slider to slide in the opposite direction along the first slide groove, so that the arc-shaped groove is still in contact with the pole of the electromagnetic, until the solenoid valve is conveyed to the left end of the two detection circular shells, the rebound force of the V-shaped spring is completely released, and the pole of the solenoid valve that has completed the test is released from the arc-shaped groove. The pole slider is reset along with the internal buffer slider, and the upward pushing effect of the buffer slider on the insulating roller disappears. The second spring rebound force pushes the detection pressure strip to reverse and reset along the hinged position of the hinged seat. The reset of the pole slider drives the compressed airbag to recover, and the air compressed into the annular airbag is drawn back into the compressed airbag through the air guide tube, so that the annular airbag is deflated again. Subsequently, the next solenoid valve to be tested is just delivered to between the other two arc-shaped grooves, and the deflated annular airbag will not hinder the normal delivery of the next solenoid valve. The above-mentioned detection process is repeated to achieve continuous and non-stop detection, thereby improving the detection efficiency.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. In the present invention, the detection component is provided to detect the solenoid valve during its transportation. Compared with the prior art, the device can complete the detection task of the solenoid valve during the transportation process without interrupting the transportation of the solenoid valve, thereby improving the detection efficiency of the solenoid valve.

[0021] 2. In the present invention, the pole of the solenoid valve continues to push the pole slide bar together with the buffer slide bar to move. Since the detection pressure bar abuts against the top of the solenoid valve pole, that is, the detection pressure bar will not continue to flip over, and the insulating roller will not continue to move upward, the wedge force between the insulating roller and the guide slope causes the buffer slide bar to slide downward along the inner wall of the buffer slide groove, and multiple first springs are compressed and stored until the insulating roller moves to the top of the buffer slide bar, and the downward displacement of the buffer slide bar reaches the maximum, that is, the first spring will not continue to be compressed, thereby ensuring that the detection pressure bar will not cause excessive extrusion on the pole of the solenoid valve. At the same time, the upward elastic force of the compressed first spring on the buffer slide bar can ensure the upward thrust of the buffer slide bar on the insulating roller, and further ensure that the detection pressure bar has a good contact effect with the top of the solenoid valve pole.

[0022] 3. In the present invention, the reaction force of the pole of the solenoid valve pushes the pole slider to move, which causes a compression effect on the compressed airbag. The air inside the compressed airbag is compressed and enters the interior of the annular airbag through the air duct, causing the deflated annular airbag to expand. After the two front and rear annular airbags expand, they can provide a limiting effect on the front and rear sides of the solenoid valve being tested, thereby improving the stability of the solenoid valve in the front and rear directions, avoiding the front and rear displacement of the solenoid valve, and ensuring the stability of the detection.

A slot 3007 is provided at one end of the top of the pole slider 307 close to the center of the detection round shell 303. The end of the V-shaped spring 3019 away from the card slot 3018 is plugged into the slot 3007.

The number of the detection modules 3020 matches the number of the detection pressure strips 3013, and the positions correspond to each other. The detection modules 3020 are electrically connected to the corresponding detection pressure strips 3013, and a restraining component is provided at the bottom of the detection round shell 303.

[0037] The second chute 306 is located at the top of the first chute 305, and the top of the first chute 305 is connected to the top of the second chute 306, and the width of the first chute 305 is greater than the width of the second chute 306;

[0038] One end of the detection pressure strip 3013 is located at the top of the arc groove 308, and an insulating roller 3015 is rotatably mounted on the end of the detection pressure strip 3013 away from the arc groove 308, and the position of the insulating roller 3015 corresponds to the position of the guide slope 3016;

[0039] The conveying component includes a conveying shaft roller 201 rotatably installed between two conveying frame strips 1, the number of conveying shaft rollers 201 is two, and the two conveying shaft rollers 201 are distributed on the left and right, and the conveying component also includes a driven shaft 207 rotatably installed between the two conveying frame strips 1, and a driven roller 208 is fixedly installed on the outer wall of the driven shaft 207, and the driven roller 208 is located between the left and right conveying shaft rollers 201, and the peripheries of the two conveying shaft rollers 201 and the driven roller 208 are jointly sleeved with a conveyor belt 202, and a plurality of left and right limit strips 203 distributed at equal distances are fixedly installed on the outer wall of the conveyor belt 202, and a reduction motor 204 is fixedly installed at the end of one of the conveying frame strips 1, and the output shaft of the reduction motor 204 is fixedly connected to the shaft end of one of the conveying shaft rollers 201, and driving bevel gears 502 are fixedly installed at both ends of the driven shaft 207, and the periphery of the driving bevel gear 502 is meshed with the driven bevel gear 501, and the inner wall of the driven bevel gear 501 is fixedly connected to the outer wall of the twisted vertical shaft 302;

[0040] Specifically, the output shaft of the reduction motor 204 drives the conveying shaft roller 201 connected thereto to rotate, and at the same time, with the cooperation of another set of conveying shaft rollers 201, the conveying belt 202 drives the left and right limit strips 203 to rotate around the two conveying shaft rollers 201. During this period, the inspector places the solenoid valve from the right end of the conveying component on the top of the conveying belt 202, and makes the solenoid valve located between the left and right limit strips 203. The solenoid valve is limited to the left and right by the left and right limit strips 203, which can prevent the solenoid valve from moving left and right. The solenoid valves added to the top of the conveying belt 202 are placed in this way, and the subsequent placement of a solenoid valve is always separated from the previously placed solenoid valve by two left and right limit strips 203, so that the spacing distance between the solenoid valves placed on the top of the conveying belt 202 each time is guaranteed to be constant.

[0041] During the rotation of the conveyor belt 202, the electromagnetic valve placed on the top of the conveyor belt 202 is continuously conveyed to the left. During the rotation of the conveyor belt 202, the driven roller 208 is also driven. The driven roller 208 rotates through the driven shaft 207 to drive the active bevel gear 502 to rotate. The active bevel gear 502 rotates through the driven bevel gear 501 to drive the twisted vertical shaft 302 to rotate inside the two twisted brackets 301. The rotation of the twisted vertical shaft 302 drives the detection round shell 303 to rotate. It should be noted that the number of teeth of the active bevel gear 502 and the driven bevel gear 501 in the device are adaptively set, so that when the conveyor belt 202 conveys one of the electromagnetic valves to the position between the two front and rear detection components, one of the pole sliders 307 of the two front and rear detection components The arc groove 308 opened at the end is just stuck on the outer wall of the two poles of the electromagnetic valve, that is to say, the rotation speed of the conveyor belt 202 of the device is adapted to the rotation speed of the detection round shell 303. After the two arc grooves 308 are stuck on the outer wall of the two poles of the electromagnetic valve, as the conveyor belt 202 continues to convey the electromagnetic valve to move to the left, the two detection round shells 303 continue to rotate synchronously, driving the pole slide 307 to rotate together. Since the pole slide 307 is affected by the abutment of the arc groove 308 and the pole of the electromagnetic valve, during the rotation of the detection round shell 303, a pole slide 307 abutting against the pole of the electromagnetic valve is affected by the reverse force of the pole of the electromagnetic valve, pushing the pole slide 307 along the first slide groove 305 to approach the center block 30 17, causing the V-shaped spring 3019 to be compressed and stored, wherein, when the pole slide bar 307 moves, it will also drive the buffer slide bar 3010 to move along the inner wall of the second slide groove 306, causing the insulating roller 3015 to gradually move toward the top of the buffer slide bar 3010 under the wedge force of the guide slope 3016, thereby lifting the insulating roller 3015 upward, causing the end of the detection pressure strip 3013 close to the insulating roller 3015 to be lifted upward, and further under the hinged action of the hinge seat 3012 and the detection pressure strip 3013, the end of the detection pressure strip 3013 close to the arc groove 308 moves downward, and the second spring 3014 is compressed, thereby abutting against the top of the pole of the solenoid valve, and at this time the insulating roller 3015 is still in When the surface of the guide slope 3016 does not reach the top of the buffer slide 3010, and as the pole of the solenoid valve continues to push the pole slide 307 and move together with the buffer slide 3010, the detection pressure strip 3013 is in contact with the top of the solenoid valve pole, that is, the detection pressure strip 3013 will not continue to flip over, and the insulating roller 3015 will not continue to move upward, so that the wedge force between the insulating roller 3015 and the guide slope 3016 causes the buffer slide 3010 to slide downward along the inner wall of the buffer groove 309, and the multiple first springs 3011 are compressed and stored until the insulating roller 3015 moves to the top of the buffer slide 3010, and the downward displacement of the buffer slide 3010 reaches the maximum, that is, the first spring 3011 will not continue to be compressed.It ensures that the detection pressure strip 3013 will not cause excessive extrusion to the pole of the electromagnetic valve. At the same time, the upward elastic force of the compressed first spring 3011 on the buffer slide 3010 can ensure the upward thrust of the buffer slide 3010 on the insulating roller 3015, and further ensures that the detection pressure strip 3013 has a good contact effect with the top of the electromagnetic valve pole. When the two detection pressure strips 3013 at the front and rear are simultaneously in contact with the tops of the two poles of the electromagnetic valve, the detection circuit is turned on to detect the electromagnetic valve, and the detection signal is transmitted to the corresponding detection module 3020, which is then transmitted to the external computer by the detection module 3020. The data is displayed on the computer screen to determine whether the electromagnetic valve is qualified or not. During this period, the electromagnetic valve is still being transported under the rotation of the conveyor belt 202, so that the device can complete the detection task of the electromagnetic valve during the transportation process, without interrupting the transportation of the electromagnetic valve, so that the detection efficiency of the electromagnetic valve is improved.

[0042] Embodiment 2: The restraining component includes a plurality of compressed air bags 401 fixedly mounted on the bottom wall of the detection round shell 303, the positions of the plurality of compressed air bags 401 correspond to the positions of the pole slider 307, and one end of the compressed air bag 401 is fixedly connected to one end of the pole slider 307, and a limiting block 402 is fixedly mounted on one side of the compressed air bag 401 away from the pole slider 307, the bottom of the limiting block 402 is fixedly connected to the bottom wall of the detection round shell 303, and a first air bag is provided through one side of the compressed air bag 401 close to the limiting block 402. Hole 403, an air guide tube 404 is fixedly installed at the periphery of the opening of the first air hole 403, the air guide tube 404 penetrates the limit block 402 and the detection round shell 303, and extends to the bottom of the detection round shell 303, a fixing sleeve 407 is fixedly installed at the bottom of the detection round shell 303, an annular air bag 405 is fixedly installed at the lower part of the outer wall of the fixing sleeve 407, and a plurality of second air holes 406 distributed at equal angles are penetrated through the inner wall of the annular air bag 405, and the openings of the plurality of second air holes 406 are respectively fixedly connected to the ends of the plurality of air guide tubes 404;

[0043] Specifically, in this embodiment, the reaction force of the pole of the solenoid valve pushes the pole slider 307 to move, which causes compression to the compressed airbag 401. The air inside the compressed airbag 401 is compressed and enters the inside of the annular airbag 405 through the air guide tube 404, causing the deflated annular airbag 405 to expand. After the two front and rear annular airbags 405 expand, they can provide a limiting effect on the front and rear sides of the solenoid valve being tested, thereby improving the stability of the solenoid valve in the front and rear directions, avoiding the front and rear displacement of the solenoid valve, and ensuring the stability of the test.

[0044] When the solenoid valve being tested is transported to the middle of the two testing circular shells 303 located in the front and rear, the displacement of the two pole sliders 307 abutting against the pole of the solenoid valve reaches the maximum value, that is, the compression of the V-shaped spring 3019 reaches the maximum, and with the continued rotation of the testing circular shell 303 and the continued rotation of the conveyor belt 202, the solenoid valve continues to be transported to the left, after which the rebound force of the V-shaped spring 3019 is gradually released, pushing the pole slider 307 to slide in the opposite direction along the first slide groove 305, so that the arc groove 308 is still abutted against the pole of the electromagnetic, until the solenoid valve is transported to the left end of the two testing circular shells 303, the rebound force of the V-shaped spring 3019 is completely released, and the pole of the solenoid valve that has completed the test moves out from the inside of the arc groove 308, and the slow The impact slider 3010 is reset along with the pole slider 307, and the upward pushing effect of the buffer slider 3010 on the insulating roller 3015 disappears. The rebound force of the second spring 3014 pushes the detection pressure strip 3013 to reverse and reset along the hinge position of the hinge seat 3012. The reset of the pole slider 307 drives the compressed air bag 401 to recover, and the air compressed into the annular air bag 405 is drawn back into the compressed air bag 401 through the air guide tube 404, so that the annular air bag 405 is deflated again, and then the next solenoid valve to be tested is just transported to between the other two arc-shaped grooves 308, and the deflated annular air bag 405 will not hinder the normal delivery of the next solenoid valve, and the above-mentioned detection process is repeated to realize continuous non-stop detection, thereby improving the detection efficiency.

The support rollers 206 are located between the two conveying shaft rollers 201 on the left and right, and the tops of the support rollers 206 are in contact with the top wall of the conveyor belt 202;

[0046] Specifically, in this embodiment, during the conveying of the solenoid valve, the supporting effect of the plurality of supporting rollers 206 on the conveyor belt 202 can ensure that the conveyor belt 202 does not sag.

[0048] Specifically, the present embodiment provides a U-shaped round tube rack 6 for fixedly supporting the barcode scanning probe 7, so that when the solenoid valve passes through the bottom of the barcode scanning probe 7 during transportation, the barcode scanning probe 7 scans and records the solenoid valves in sequence, so as to facilitate the subsequent barcode scanning and differentiation of qualified and unqualified solenoid valves.

[0049] Embodiment 5: Two fixed columns 8 distributed on the left and right are fixedly installed on the top of the conveying frame bar 1, and a protective tile cover 9 is fixedly installed between the two fixed columns 8. The protective tile cover 9 is located on the periphery of the detection round shell 303;

[0050] Specifically, in this embodiment, fixed columns 8 are provided to provide fixed support for the protective tile covers 9. The protective tile covers 9 can protect the peripheries of the two detection circular shells 303, thereby improving the safety of the device.

[0051] The testing method of the durability testing device of the solenoid valve comprises the following steps:

[0052] S1, the output shaft of the reduction motor 204 drives the connected conveyor shaft roller 201 to rotate, and at the same time, with the cooperation of another set of conveyor shaft rollers 201, the conveyor belt 202 drives the left and right limit strips 203 to rotate around the two conveyor shaft rollers 201. During this period, the inspector places the solenoid valve from the right end of the conveying component on the top of the conveyor belt 202, and makes the solenoid valve located between the left and right limit strips 203. The solenoid valves added to the top of the conveyor belt 202 are placed in this way, and the subsequent placement of a solenoid valve must always be separated from the previous solenoid valve by two left and right limit strips 203.

[0053] S2, during the rotation of the conveyor belt 202, the solenoid valve placed on the top of it is continuously conveyed to the left. During the conveying of the solenoid valve, the support of the multiple support rollers 206 on the conveyor belt 202 can ensure that the conveyor belt 202 does not sag, and the conveyor belt 202 will also drive the driven roller 208 during the rotation. The driven roller 208 rotates through the driven shaft 207 to drive the active bevel gear 502 to rotate. The active bevel gear 502 rotates through the driven bevel gear 501 to drive the twisted vertical shaft 302 to rotate inside the two twisted brackets 301. The rotation of the twisted vertical shaft 302 drives the detection circular shell 303 to rotate. When the conveyor belt 202 conveys one of the solenoid valves to the position between the two front and rear detection components, one of the poles in the two front and rear detection components slides. The arc groove 308 opened at the end of the bar 307 is just stuck on the outer wall of the two poles of the electromagnetic valve. After the two arc grooves 308 are stuck on the outer wall of the two poles of the electromagnetic valve, as the conveyor belt 202 continues to convey the electromagnetic valve to move to the left, the two detection circular shells 303 continue to rotate synchronously, driving the pole slide 307 to rotate together. Since the pole slide 307 is affected by the abutment of the arc groove 308 and the pole of the electromagnetic valve, during the rotation of the detection circular shell 303, a pole slide 307 abutting against the pole of the electromagnetic valve is affected by the reverse force of the pole of the electromagnetic valve, pushing the pole slide 307 to move along the first slide groove 305 toward the direction close to the center block 3017, causing the V-shaped spring 3019 to be compressed and stored. During the movement, the buffer slide 3010 is also driven to move along the inner wall of the second slide groove 306, causing the insulating roller 3015 to gradually move toward the top of the buffer slide 3010 under the wedge force of the guide slope 3016, thereby lifting the insulating roller 3015 upward, causing the end of the detection pressure strip 3013 close to the insulating roller 3015 to lift upward, and further under the hinged action of the hinge seat 3012 and the detection pressure strip 3013, the end of the detection pressure strip 3013 close to the arc groove 308 moves downward, and the second spring 3014 is compressed, thereby abutting against the top of the pole of the electromagnetic valve. At this time, the insulating roller 3015 is still on the surface of the guide slope 3016 and has not reached the top of the buffer slide 3010, and as the pole of the electromagnetic valve continues to move, the insulating roller 3015 is lifted upward. Continue to push the top pole slider 307 together with the buffer slider 3010 to move. Since the detection pressure strip 3013 abuts against the top of the solenoid valve pole, that is, the detection pressure strip 3013 will not continue to flip over, and the insulating roller 3015 will not continue to move upward, which makes the wedge force between the insulating roller 3015 and the guide slope 3016 cause the buffer slider 3010 to slide downward along the inner wall of the buffer slide groove 309. The multiple first springs 3011 are compressed and stored until the insulating roller 3015 moves to the top of the buffer slider 3010. The downward displacement of the buffer slider 3010 reaches the maximum, that is, the first spring 3011 will not continue to be compressed. When the two detection pressure strips 3013 at the front and rear abut against the tops of the two poles of the solenoid valve at the same time, the detection circuit is turned on.The electromagnetic valve is tested, and the tested signal is transmitted to the corresponding detection module 3020, and then transmitted to the external computer by the detection module 3020, and the data is displayed on the computer screen to judge whether the electromagnetic valve is qualified or not. During this period, the electromagnetic valve is still conveyed under the rotation of the conveyor belt 202. During this period, the movement of the driven shaft 207 will cause compression to the compressed airbag 401. The air inside the compressed airbag 401 is compressed and enters the inside of the annular airbag 405 through the air guide tube 404, causing the deflated annular airbag 405 to expand and clamp the electromagnetic valve before and after;

[0054] S3, when the solenoid valve being tested is transported to the middle of the two testing circular shells 303 located in the front and rear, the displacement of the two pole sliders 307 abutting against the pole of the solenoid valve reaches the maximum value, that is, the compression of the V-shaped spring 3019 reaches the maximum, and with the continued rotation of the testing circular shell 303 and the continued rotation of the conveyor belt 202, the solenoid valve continues to be transported to the left, after which the rebound force of the V-shaped spring 3019 is gradually released, pushing the pole slider 307 to slide in the opposite direction along the first slide groove 305, so that the arc groove 308 is still abutting against the pole of the electromagnetic, until the solenoid valve is transported to the left end of the two testing circular shells 303, the rebound force of the V-shaped spring 3019 is completely released, and the pole of the solenoid valve that has completed the test moves out from the inside of the arc groove 308, and The buffer slider 3010 is reset along with the pole slider 307, and the upward pushing effect of the buffer slider 3010 on the insulating roller 3015 disappears. The rebound force of the second spring 3014 pushes the detection pressure strip 3013 to reverse and reset along the hinge position of the hinge seat 3012. The reset of the pole slider 307 drives the compressed air bag 401 to recover, and the air compressed into the annular air bag 405 is drawn back into the compressed air bag 401 through the air guide tube 404, so that the annular air bag 405 is deflated again, and then the next solenoid valve to be tested is just transported to between another set of two arc-shaped grooves 308, and the deflated annular air bag 405 will not hinder the normal delivery of the next solenoid valve, and the above-mentioned detection process is repeated to achieve a continuous and non-stop detection, thereby improving the detection efficiency.

[0055] When the durability test device of the solenoid valve of the present scheme is working, the output shaft of the reduction motor 204 drives the conveying shaft roller 201 connected thereto to rotate, and at the same time, with the cooperation of another set of conveying shaft rollers 201, the conveying belt 202 drives the left and right limit strips 203 to rotate around the two conveying shaft rollers 201. During this period, the inspector places the solenoid valve from the right end of the conveying component on the top of the conveying belt 202, and makes the solenoid valve located between the left and right limit strips 203. The solenoid valve is limited to the left and right by the left and right limit strips 203, which can prevent the solenoid valve from moving left and right. The solenoid valves added to the top of the conveying belt 202 subsequently are all placed in this way, and the subsequent placement of a solenoid valve must always be separated from the previously placed solenoid valve by two left and right limit strips 203, so that the spacing distance between the solenoid valves placed on the top of the conveying belt 202 each time can be guaranteed to be constant.

[0056] During the rotation of the conveyor belt 202, the electromagnetic valve placed on the top of it is continuously conveyed to the left. During the conveying of the electromagnetic valve, the support effect of multiple support rollers 206 on the conveyor belt 202 can ensure that the conveyor belt 202 does not sag, and the conveyor belt 202 will also drive the driven roller 208 during the rotation. The driven roller 208 rotates through the driven shaft 207 to drive the active bevel gear 502 to rotate. The active bevel gear 502 rotates through the driven bevel gear 501 to drive the twisted vertical shaft 302 to rotate inside the two twisted brackets 301. The rotation of the twisted vertical shaft 302 drives the detection circular shell 303 to rotate. It should be noted that the number of teeth of the active bevel gear 502 and the driven bevel gear 501 in the present device is adaptively set so that the conveyor belt 202 can When a solenoid valve is transported to the position between the front and rear two detection components, the arc-shaped groove 308 opened at the end of one of the pole slides 307 of the two front and rear detection components is just stuck on the outer walls of the two poles of the solenoid valve, that is to say, the rotation speed of the conveyor belt 202 of the present device is adapted to the rotation speed of the detection round shell 303. After the two arc-shaped grooves 308 are stuck on the outer walls of the two poles of the solenoid valve, as the conveyor belt 202 continues to transport the solenoid valve to move to the left, the two detection round shells 303 continue to rotate synchronously, driving the pole slide 307 to rotate together. Since the pole slide 307 is affected by the abutment of the arc-shaped groove 308 and the pole of the solenoid valve, during the rotation of the detection round shell 303, a pole slide abutting against the pole of the solenoid valve The bar 307 is subjected to the reverse force of the electromagnetic valve pole, pushing the pole bar 307 to move along the first slide groove 305 toward the direction close to the center block 3017, causing the V-shaped spring 3019 to be compressed and stored. In the process of the pole bar 307 moving, the buffer bar 3010 is also driven to move along the inner wall of the second slide groove 306, causing the insulating roller 3015 to gradually move toward the top of the buffer bar 3010 under the wedge force of the guide slope 3016, thereby lifting the insulating roller 3015 upward, causing the end of the detection pressure bar 3013 close to the insulating roller 3015 to be lifted upward, and further under the hinged action of the hinge seat 3012 and the detection pressure bar 3013, the end of the detection pressure bar 3013 close to the arc groove 308 moves downward 3014 is compressed and abuts against the top of the pole of the electromagnetic valve. At this time, the insulating roller 3015 is still on the surface of the guide slope 3016 and has not reached the top of the buffer slide 3010. As the pole of the electromagnetic valve continues to push the pole slide 307 and the buffer slide 3010, the detection pressure strip 3013 abuts against the top of the pole of the electromagnetic valve, that is, the detection pressure strip 3013 will not continue to flip over, and the insulating roller 3015 will not continue to move upward. This makes the wedge force of the insulating roller 3015 and the guide slope 3016 cause the buffer slide 3010 to slide downward along the inner wall of the buffer slide groove 309. The multiple first springs 3011 are compressed and stored until the insulating roller 3015 moves to the top of the buffer slide 3010.The downward displacement of the buffer slide 3010 reaches the maximum, that is, the first spring 3011 will not continue to be compressed. When the two detection pressure strips 3013 at the front and rear are simultaneously in contact with the tops of the two poles of the solenoid valve, the detection circuit is turned on, the detection of the solenoid valve is realized, and the detection signal is transmitted to the inside of the corresponding detection module 3020, and then transmitted to the external computer by the detection module 3020. The data is displayed on the computer screen to judge whether the solenoid valve is qualified or not. During this period, the solenoid valve is still being transported under the rotation of the conveyor belt 202, so that the device is in the process of transportation. The detection task of the solenoid valve can be completed without interrupting the delivery of the solenoid valve, so that the detection efficiency of the solenoid valve is improved. During the process, the movement of the driven shaft 207 will cause compression to the compressed airbag 401, and the air inside the compressed airbag 401 is compressed and enters the inside of the annular airbag 405 through the air guide tube 404, causing the deflated annular airbag 405 to expand. After the two front and rear annular airbags 405 expand, they can provide a limiting effect on the front and rear sides of the solenoid valve being detected, thereby improving the stability of the solenoid valve in the front and rear directions, avoiding the front and rear displacement of the solenoid valve, and ensuring the stability of the detection;

[0057] When the solenoid valve being tested is transported to the middle of the two testing circular shells 303 located in the front and rear, the displacement of the two pole sliders 307 abutting against the pole of the solenoid valve reaches the maximum value, that is, the compression of the V-shaped spring 3019 reaches the maximum, and with the continued rotation of the testing circular shell 303 and the continued rotation of the conveyor belt 202, the solenoid valve continues to be transported to the left, after which the rebound force of the V-shaped spring 3019 is gradually released, pushing the pole slider 307 to slide in the opposite direction along the first slide groove 305, so that the arc groove 308 is still abutted against the pole of the electromagnetic, until the solenoid valve is transported to the left end of the two testing circular shells 303, the rebound force of the V-shaped spring 3019 is completely released, and the pole of the solenoid valve that has completed the test moves out from the inside of the arc groove 308, and the slow The impact slider 3010 is reset along with the pole slider 307, and the upward pushing effect of the buffer slider 3010 on the insulating roller 3015 disappears. The rebound force of the second spring 3014 pushes the detection pressure strip 3013 to reverse and reset along the hinge position of the hinge seat 3012. The reset of the pole slider 307 drives the compressed air bag 401 to recover, and the air compressed into the annular air bag 405 is drawn back into the compressed air bag 401 through the air guide tube 404, so that the annular air bag 405 is deflated again, and then the next solenoid valve to be tested is just transported to between the other two arc-shaped grooves 308, and the deflated annular air bag 405 will not hinder the normal delivery of the next solenoid valve, and the above-mentioned detection process is repeated to achieve a continuous and non-stop detection, thereby improving the detection efficiency.

[0058] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

The solenoid valve that is subsequently placed on the top of the conveying belt (202) and the solenoid valve that is subsequently placed must always be separated from the previously placed solenoid valve by two left and right limit strips (203); S2, the conveyor belt (202) continuously conveys the electromagnetic valve placed on the top thereof to the left during the rotation. During the conveying of the electromagnetic valve, the support effect of the plurality of support rollers (206) on the conveyor belt (202) ensures that the conveyor belt (202) does not sag, and the conveyor belt (202) also drives the driven roller (208) during the rotation. The driven roller (208) rotates through the driven shaft (207) to drive the driving bevel gear (502) to rotate. The driving bevel gear (502) rotates through the driven bevel gear (501) to drive the twisted vertical shaft (302) to rotate inside the two twisted brackets (301). The rotation of the twisted vertical shaft (302) drives the detection circular shell (303) to rotate, and the conveyor belt (202) conveys one of the electromagnetic valves to the two front and rear ones. When the detection components are positioned between each other, the arc groove (308) formed at the end of one of the pole sliders (307) of the two front and rear detection components is just stuck on the outer walls of the two poles of the solenoid valve. After the two arc grooves (308) are stuck on the outer walls of the two poles of the solenoid valve, as the conveyor belt (202) continues to convey the solenoid valve to move to the left, the two detection circular shells (303) continue to rotate synchronously, driving the pole sliders (307) to rotate together. Since the pole sliders (307) are subjected to the abutment effect of the arc grooves (308) and the poles of the solenoid valve, during the rotation of the detection circular shell (303), a pole slider (307) abutting against the poles of the solenoid valve is subjected to the reverse force of the poles of the solenoid valve, pushing the pole sliders (307) along the first The slide groove (305) moves in a direction close to the center block (3017), causing the V-shaped spring (3019) to be compressed and stored. When the pole slide bar (307) moves, it also drives the buffer slide bar (3010) to move along the inner wall of the second slide groove (306), causing the insulating roller (3015) to gradually move toward the top of the buffer slide bar (3010) under the wedge force of the guide slope (3016), thereby lifting the insulating roller (3015) upward, causing the end of the detection pressure strip (3013) close to the insulating roller (3015) to be lifted upward, and further under the hinged action of the hinge seat (3012) and the detection pressure strip (3013), the end of the detection pressure strip (3013) close to the arc groove (308) moves downward. The second spring (3014) is compressed and abuts against the top of the pole of the electromagnetic valve. At this time, the insulating roller (3015) is still on the surface of the guide slope (3016) and has not reached the top of the buffer slide bar (3010). As the pole of the electromagnetic valve continues to push the pole slide bar (307) and move together with the buffer slide bar (3010), the detection pressure bar (3013) abuts against the top of the pole of the electromagnetic valve, that is, the detection pressure bar (3013) will not continue to flip over, and the insulating roller (3015) will not continue to move upward. This causes the wedge force between the insulating roller (3015) and the guide slope (3016) to cause the buffer slide bar (3010) to slide downward along the inner wall of the buffer slide groove (309), and the plurality of first springs (3011) are compressed and force is accumulated.Until the insulating roller (3015) moves to the top of the buffer slide bar (3010), the displacement of the buffer slide bar (3010) moving downward reaches the maximum, that is, the first spring (3011) will not continue to be compressed. When the two front and rear detection pressure strips (3013) simultaneously abut against the tops of the two poles of the electromagnetic valve, the detection circuit is turned on, the electromagnetic valve is detected, and the detection signal is transmitted to the inside of the corresponding detection module (3020), and then transmitted by the detection module (3020) to the external computer, and the data is displayed on the display screen of the computer to determine whether the electromagnetic valve is qualified or not. During this period, the electromagnetic valve is still conveyed under the rotation of the conveyor belt (202). During this period, the movement of the driven shaft (207) will cause compression to the compressed airbag (401). The air inside the compressed airbag (401) is compressed and enters the inside of the annular airbag (405) through the air guide tube (404), causing the deflated annular airbag (405) to expand and clamp the electromagnetic valve front and back; S3, when the solenoid valve being tested is conveyed to the middle of the two detection circular shells (303) located in the front and rear, the displacement of the two pole sliders (307) abutting against the pole of the solenoid valve reaches the maximum value, that is, the compression of the V-shaped spring (3019) reaches the maximum, and as the detection circular shell (303) continues to rotate and the conveyor belt (202) continues to rotate, the solenoid valve continues to be conveyed to the left, after which the rebound force of the V-shaped spring (3019) is gradually released, pushing the pole slider (307) to slide in the opposite direction along the first slide groove (305), so that the arc-shaped groove (308) is still abutting against the pole of the electromagnetic, until the solenoid valve is conveyed to the left end of the two detection circular shells (303), the rebound force of the V-shaped spring (3019) is completely released, and the pole of the solenoid valve that has completed the test is released from the arc-shaped groove The detection pressure strip (3013) is moved out of the groove (308), and the buffer slide bar (3010) is reset along with the pole slide bar (307). The upward push effect of the buffer slide bar (3010) on the insulating roller (3015) disappears. The rebound force of the second spring (3014) pushes the detection pressure strip (3013) to reverse and reset along the hinge position of the hinge seat (3012). The reset of the pole slide bar (307) drives the compressed air bag (401) to recover, and the air compressed into the annular air bag (405) is drawn back into the compressed air bag (401) through the air guide tube (404), so that the annular air bag (405) is deflated again. Subsequently, the next solenoid valve to be detected is just transported to between the other two arc-shaped grooves (308), and the deflated annular air bag (405) will not hinder the normal delivery of the next solenoid valve.
