[0046] The test feeding channel 22 and the temperature test chamber 24 are installed on the test installation base 21;
[0047] The test conveying assembly 23 includes: a test piece driver 231, a test material conveying plate 232 and a bin driver 233;
[0048] The fixed end of the test piece driver 231 is installed on the test installation base 21, and the output end thereof is connected to the test material transfer plate 232, and is used to drive the test material transfer plate 232 to move, so that the test material transfer plate 232 passes through the output port of the test feeding channel 22 and the input port of the temperature test chamber 24; the chamber entry driver 233 is installed on the test installation base 21, and the output end thereof moves toward the input port of the temperature test chamber 24 and the test material transfer plate 232;
[0049] The performance tester 25 is installed in the temperature test chamber 24 and is used to perform a performance test on the thermal protector passing through the inside or outside of the temperature test chamber 24 .
[0050] The performance testing device is used to perform performance testing on the thermal protector 01. It can be used to place the thermal protector 01 in the temperature testing chamber 24. It has the functions of fully automatic feeding, testing and unloading, so as to achieve the effect of accurately, quickly and in large quantities testing the performance of the thermal protector.
[0051] Specifically, the test feeding channel 22 is used to output the thermal protector 01; under the driving action of the output end of the test piece driver 231, the test material transfer plate 232 can be driven to move, so that the test material transfer plate 232 can move between the output port of the test feeding channel 22 and the input port of the temperature test chamber 24; the test feeding channel 22 transfers the thermal protector to the test material transfer plate 232, the output end of the test piece driver 231 is reset, and the thermal protector is sent to the input port of the temperature test chamber 24; the output end of the entry driver 233 is aligned with the direction of the input port of the temperature test chamber 24 and the test material transfer plate 232; the output end of the entry driver 233 moves, and the thermal protector located at the test material transfer plate 232 is continuously sent into the temperature test chamber 24, achieving the effect of sending the thermal protector into the temperature test chamber 24. The temperature test chamber 24 is provided with different temperature sections, so that the thermal protector stays for a period of time under different temperature environments, so as to test the changes in the situation of the thermal protector under the specified temperature conditions. The performance tester 25 is used to perform performance tests on the thermal protector inside or outside the temperature test chamber 24. The performance tester 25 can test the performance indicators of the existing thermal protector, such as appearance and conductivity; appearance performance indicators such as dimensional changes; conductivity performance indicators such as internal resistance, etc.
[0052] The test piece driver 231 and / or the magazine driver 233 are replaced by a well-known horizontal driver, such as a cylinder, or a driver in which a motor and a screw are matched.
[0053] When the thermal protector moves in the test feeding channel 22, the test feeding channel 22 can be replaced by a well-known horizontal moving drive device, such as a conveyor belt, etc.; or the thermal protectors can be arranged and continuously introduced, and the introduced thermal protectors can be driven by a horizontal driver to continuously move forward one unit, and finally the thermal protector can be fed into the test feeding plate 232.
[0054] Preferably, it further comprises: a primary inspection discharge component 26; the primary inspection discharge component 26 comprises: a primary inspection discharge channel 261;
[0055] The input port of the initial inspection discharge channel 261 and the output port of the test feeding channel 22 are arranged on both sides of the test material transfer plate 232 opposite to each other;
[0056] The initial inspection discharge component 26 is used to select the thermal protectors sent to the test feed plate 232; if the thermal protector is of qualified quality, the test feed plate 232 is controlled to send the thermal protector located at the output port of the test feed channel 22 to the input port of the temperature test chamber 24; if the thermal protector is of unqualified quality, the unqualified thermal protector is discharged from the output port of the initial inspection discharge channel 261, and the surface detection device 28 arranged above the test feed channel 22 is used to identify the surface of the thermal protector.
[0057] Preferably, the primary inspection discharge assembly 26 comprises: a primary inspection discharge driver 262 and a primary inspection discharge block 263;
[0058] The output end of the primary inspection discharge driver 262 is connected to the primary inspection discharge block 263 , and is used to drive the primary inspection discharge block 263 to extend into and out of the primary inspection discharge channel 261 .
[0059] Specifically, if the system finds an unqualified thermal protector, the initial inspection discharge driver 262 is started, so that the output end of the initial inspection discharge driver 262 drives the initial inspection discharge block 263 to move, and the initial inspection discharge block 263 disengages from the output port of the initial inspection discharge channel 261, and the unqualified thermal protector will enter the initial inspection discharge channel 261; the thermal protector will leave the test feeding channel 22 and enter the initial inspection discharge channel 261.
[0060] Furthermore, initially, the preliminary inspection discharge block 263 can extend into the preliminary inspection discharge channel 261, and the preliminary inspection discharge block 263 can extend into the input port of the preliminary inspection discharge channel 261, thereby restricting the thermal protector from entering the preliminary inspection discharge channel 261; and when the system detects an abnormality in the thermal protector at the test material transfer plate 232 or the test feed channel 22, the preliminary inspection discharge block 263 moves, allowing the thermal protector to enter the preliminary inspection discharge channel 261, thereby achieving the effect of isolating unqualified thermal protectors.
[0061] Preferably, the temperature testing chamber 24 comprises: a low temperature sealed chamber 241 and a high temperature sealed chamber 242;
[0062] The low-temperature sealed chamber 241 is communicated with the high-temperature sealed chamber 242 .
[0063] The temperature of the low-temperature sealed chamber 241 is lower than the temperature of the high-temperature sealed chamber 242; the low-temperature sealed chamber 241 is connected to the high-temperature sealed chamber 242; the input port of the low-temperature sealed chamber 241 can be connected to the test material transfer plate 232, and the output port of the low-temperature sealed chamber 241 can be connected to the input port of the high-temperature sealed chamber 242, that is, the low temperature is measured first and then the high temperature; or the input port of the high-temperature sealed chamber 242 is connected to the test material transfer plate 232, and the output port of the high-temperature sealed chamber 242 is connected to the input port of the low-temperature sealed chamber 241, that is, the high temperature is measured first and then the low temperature.
[0064] Temperature control devices are provided in the low-temperature sealed chamber 241 and the high-temperature sealed chamber 242 to keep the low-temperature sealed chamber 241 at a low temperature and the high-temperature sealed chamber 242 at a high temperature; the thermal protector is a temperature-sensitive component. During the testing of the low-temperature sealed chamber 241 and the high-temperature sealed chamber 242, the physical parameters of the thermal protector will change. This scheme tests the performance changes of the thermal protector by adjusting different temperatures, thereby realizing large-scale and fully automatic testing of the performance of the thermal protector.
[0065] Preferably, the performance tester further comprises: an exit detection component 27;
[0066] The warehouse exit detection component 27 is installed in at least one of the low-temperature sealed warehouse 241 and the high-temperature sealed warehouse 242;
[0067] The outbound detection assembly 27 includes: an outbound detection support 271, an outbound detection driver 272 and a detection proximity switch 273;
[0068] The warehouse exit detection support seat 271 is connected to the temperature testing chamber 24; the fixed end of the warehouse exit detection driver 272 is fixed to the warehouse exit detection support seat 271, and its output end is connected to the detection approach switch 273, which is used to drive the detection approach switch 273 to vertically extend into the temperature testing chamber 24, so that the detection approach switch 273 is close to or contacts the thermal protector.
[0069] The warehouse exit detection component 27 can be installed in the low temperature sealed warehouse 241 and / or the high temperature sealed warehouse 242, and is located at the input port, output port or middle position of the two. Figure 1 The warehouse exit detection component 27 is arranged at the output port of the low-temperature sealed warehouse 241 and the high-temperature sealed warehouse 242.
[0070] When the thermal protector passes through the exit detection assembly 27, the exit detection driver 272 drives the detection proximity switch 273 to move vertically, and moves the detection proximity switch 273 close to the thermal protector; and the thermal protector will have a structural change after the temperature changes. For example, at high temperature, its double pieces drive the springs to tilt up, and the thermal protector is in a disconnected state; at low temperature, the springs do not tilt up, and the thermal protector is in a connected state; and here, in order to detect the state of the thermal protector after it is discharged from the low-temperature sealed chamber 241 and the high-temperature sealed chamber 242; if the thermal protector When the performance of the thermal protector is unqualified, it will tilt after passing through the low-temperature sealed chamber 241, or will not tilt after passing through the high-temperature sealed chamber 242; at low temperatures, generally, since the springs in qualified thermal protectors will not tilt, the detection close switch 273 will not touch the thermal protector after it falls, and will not trigger the detection close switch 273 to record the position of the unqualified thermal protector; and when the detection close switch 273 falls and contacts any tilted end of the thermal protector, the detection close switch 273 will record the unqualified position of the thermal protector and discharge the unqualified thermal protector at the rear end. At high temperatures, similarly, the springs of generally qualified thermal protectors will tilt, and if the detection close switch 273 does not contact any tilted end of the thermal protector after it falls, it is unqualified.
[0071] Among them, the out-of-warehouse detection driver 272 can be a known linear drive drive, such as a cylinder, or a combination of a motor and a screw; the detection proximity switch 273 is indirectly or directly connected to the output end of the out-of-warehouse detection driver 272. The out-of-warehouse detection driver 272 of this solution includes: a vertical positioning driver 2721, a vertical movable positioning plate 2722 and a vertical positioning guide column 2723; the vertical positioning guide column 2723 is installed on the out-of-warehouse detection support seat 271; the vertical movable positioning plate 2722 can be vertically movably installed on the vertical positioning guide column 2723; the vertical positioning driver 2721 is fixed to the out-of-warehouse detection support seat 271, and its output end is connected to the vertical movable positioning plate 2722, which is used to drive the vertical movable positioning plate 2722 to move; and the detection proximity switch 273 is installed on the driving vertical movable positioning plate 2722, and the detection proximity switch 273 moves under the driving action of the vertical positioning driver 2721.
[0072] Preferably, the number of the temperature testing chambers 24 is at least two.
[0073] When the number of temperature test chambers 24 is at least 2, that is, the number of temperature test chambers 24 is multiple; the output end of the test piece driver 231 drives the test material transfer plate 232 to move to the input port of each temperature test chamber 24, and the thermal protector is sent into the chamber through the corresponding chamber entry driver 233 of each temperature test chamber 24. It is only necessary to control the output end of the test piece driver 231 so that the test material transfer plate 232 receives the thermal protector from the test feeding channel 22, and transfers the thermal protector to different temperature test chambers 24 through the chamber entry driver 233, so as to realize batch and multiple delivery of the thermal protector into the temperature test chamber 24.
[0074] Preferably, the initial inspection discharge block 263 is provided with at least one introduction portion 2321 ; when the introduction portion 2321 moves, it passes through the output port of the test feeding channel 22 and the input port of the temperature test chamber 24 .
[0075] The introduction part 2321 is a structure for introducing the thermal protector, and can preferably limit the thermal protector so that the transmission process of the thermal protector is more stable and will not loosen, such as a groove structure, a protrusion structure, a accommodating cavity, an adsorption structure, etc. The number of introduction parts 2321 can be set to multiple, and preferably the distance a between the introduction parts 2321 and the introduction parts 2321 corresponds to the distance b between the input ports of the temperature test chamber 24 and the temperature test chamber 24. When a=b, when the first introduction part 2321 takes out the thermal protector in the test feeding channel 22, the n+1th introduction part 2321 will deliver the thermal protector at the input port of other temperature test chambers 24, achieving the effect of synchronous discharge. Figure 2 and Figure 7The initial inspection discharge block 263 is provided with two introduction parts 2321. When the first introduction part 2321 takes out the thermal protector in the test feeding channel 22, the second introduction part 2321 discharges the material in one of the temperature test chambers 24; and after the initial inspection discharge block 263 moves, when the first introduction part 2321 moves to another temperature test chamber 24 to discharge the material, the second introduction part 2321 will take out the thermal protector in the test feeding channel 22. The synchronous feeding and taking out are repeated in this way, thereby improving the testing efficiency of the thermal protector.
[0076] Preferably, the performance tester 25 comprises: an electrical performance test base 251, an electrical performance test channel 252 and an internal resistance tester 253;
[0077] The electrical performance test channel 252 is installed on the electrical performance test base 251; the input port of the electrical performance test channel 252 is connected to the temperature test chamber 24; the internal resistance tester 253 is installed on the electrical performance test channel 252 for testing the internal resistance of the thermal protector.
[0078] After the thermal protector is output from the temperature test chamber 24, it enters the electrical performance test channel 252; the electrical performance test channel 252 is provided with an internal resistance tester 253, which can be used to test the internal resistance of the thermal protector to detect the performance change of the thermal protector after the temperature changes, so as to facilitate the discharge of unqualified parts at the back end. The performance tester 253 can be set at the input port of the temperature test chamber 24, the output port of the temperature test chamber 24, or the middle position of the temperature test chamber 24, such as Figure 1 This is only one embodiment in which the performance tester 25 is arranged at the output port of the temperature test chamber 24. Furthermore, in order to ensure the accuracy of the internal resistance test, the performance tester 25 is provided with an internal limit test pressure head 2543; the internal limit test pressure head 2543 can be vertically raised and lowered to extend into the electrical performance test channel 252, and is used to press the thermal protector downward toward the internal resistance tester, thereby preventing the thermal protector from loosening during the test. The performance tester 25 includes: a pressure head drive assembly 254; the pressure head drive assembly 25 includes: a pressure head drive base 2541 and a pressure head drive driver 2542;
[0079] The pressure head driving base 2541 is installed on the electrical performance test base 251; the fixed end of the pressure head driving driver 2542 is installed on the pressure head driving base 2541, and its output end is connected to the internal limit test pressure head 2543, which is used to drive the pressure head to drive the internal limit test pressure head 2543 to move vertically, so that the internal limit test pressure head 2543 extends into the electrical performance test channel 252, and presses the thermal protector against the internal resistance tester 253; the pressure head driving limit column 2543 is distributed on both sides of the electrical performance test channel 252.
[0080] Preferably, the performance tester 25 comprises: a backstop assembly 255;
[0081] The backstop assembly 255 includes: a backstop base 2551, a backstop driver 2552 and a backstop limit column 2553;
[0082] The anti-retreat base 2551 is installed on the electrical performance test base 251; the fixed end of the anti-retreat driver 2552 is installed on the anti-retreat base 2551, and its output end is connected to the anti-retreat limit column 2553, which is used to drive the anti-retreat limit column 2553 to move vertically so that the anti-retreat limit column 2553 extends into the electrical performance test channel 252; the anti-retreat limit columns 2553 are distributed on both sides of the electrical performance test channel 252.
[0083] The thermal protector is provided with a base positioning hole 1917 for positioning during batch processing of the thermal protector. The backstop driver 2552 indirectly or directly drives the backstop limit post 2553 to move the backstop limit post 2553 vertically; the backstop limit post 2553 can vertically extend into the electrical performance test channel 252 and the part extending into the base positioning hole 1917 to prevent the thermal protector from tilting; since the thermal protector will expand or contract to varying degrees, the backstop limit post 2553 is provided. After the standard thermal protector expands, its size is stable, and the backstop limit posts 2553 on both sides can move the two ends of the thermal protector into a stable state. Accurate positioning ensures that the thermal protector can accurately contact the internal resistance tester 253 and accurately measure the internal resistance. For non-standard thermal protectors, after their size expands, the base positioning hole 1917 and the stop limit column 2553 are misaligned, and the stop limit column 2553 cannot position the thermal protector through the base positioning hole 1917. As a result, the stop limit column 2553 on one side may be inaccurately positioned and the internal resistance test may be inaccurate. The system will judge the thermal protector with non-standard internal resistance and discharge it at the rear end.
[0084] Preferably, it also includes: a surface detection device 28;
[0085] The surface detection device 28 is disposed at at least one of the test feeding channel 22 , the test material transfer plate 232 and the temperature test chamber 24 .
[0086] The surface detection device 28 can be set at any position in the performance test device, such as the test feed channel 22, the test feed plate 232 and the temperature test chamber 24; if the surface detection device 28 is set at the test feed channel 22, when it is found that the thermal protector of the test feed channel 22 has a problem, the unqualified thermal protector will be directly discharged through the initial inspection discharge component 26; and if it appears in the test feed plate 232 or the temperature test chamber 24, the surface detection device 28 will directly mark the position of the thermal protector, and when the thermal protector moves to the designated unit, it will be discharged. The surface detection device 28 is a well-known device, such as industrial cameras, infrared detection devices, etc., used to find surface problems of thermal protectors.
