Description

Technical Field

[0001] The present invention relates to the technical field of conductivity detection devices, and specifically to a conductivity detection device for the production of switch connectors. Background Art

[0002] With the rapid development of electronic devices towards high integration, high frequency, and high power, as a connection component for current transmission and signal interaction, the reliability of the electrical conductivity of switch connectors directly determines the stability and safety of the entire machine system. Especially in the fields of new energy vehicles, 5G communication, industrial automation, etc., switch connectors need to withstand the tests of high-frequency signal transmission, large current loads, and complex environmental stresses. And conductivity, as the core index to measure the electrical conductivity of connectors, the detection accuracy and efficiency have become the key links in production quality control.

[0003] When detecting switch connectors, especially multi-channel switch connectors, since multiple channels need to be continuously detected, the detection head often operates at a high temperature. Long-term high-temperature operation not only easily causes the detection head to deform and shorten its service life, but also may affect the accuracy of the test and the safety of the detection equipment. In addition, to ensure the detection accuracy, a high cleanliness of the connector body and the detection head is required during the detection of multi-channel switch connectors. Given the large number of channels, manual inspection and cleaning are not only time-consuming and inefficient, but also the maintenance of cleanliness depends on the skill level of the operator. Summary of the Invention

[0004] The purpose of the present invention is to provide a conductivity detection device for the production of switch connectors to solve the problems raised in the prior art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A conductivity detection device for the production of switch connectors, including a machine body, on which a machine cover is rotatably installed, a fixed steering component is rotatably installed on the machine body, a centering and dust-removing component is slidably installed on the machine body, and a detection component is slidably installed on the machine body; the detection component includes a second electric slider, a detection table is installed on the second electric slider, a detection head is installed on the detection table, and a heat dissipation detector is installed on the detection head.

[0006] A control system is provided inside the machine body, and the control system is used to control the entire conductivity detection device. The detection head is used to closely dock with the connection holes of the switch connector; the detection table applies a controllable current to the switch connector through the detection head and transmits the feedback voltage signal to the control system, and the control system evaluates the conductivity of the switch connector according to the measured response parameters, thereby completing the detection. The second electric slider is used to drive the entire detection component to slide on the machine body.

[0007] Furthermore, the heat dissipation detector includes a heat dissipation casing, which is installed on the detection head, a heat dissipation ring is rotatably installed in the heat dissipation casing, a heat dissipation motor is installed in the heat dissipation casing, a transmission gear is installed on the output shaft of the heat dissipation motor, the transmission gear is meshed with the heat dissipation ring for transmission, a control panel is rotatably installed on the heat dissipation casing, a conversion component is installed on the heat dissipation casing, and the conversion component is connected to the control panel.

[0008] Furthermore, a heat-conducting ring is provided on the heat dissipation casing, the heat-conducting ring is connected to the detection head, a temperature-sensing plate is installed on the heat-conducting ring, the temperature-sensing plate is close to the control panel, a plurality of first air outlets are provided on the heat dissipation casing, a heat dissipation port is provided on the heat dissipation casing, a purge chamber is provided on the heat dissipation casing, the heat dissipation ring is located in the purge chamber, and an air inlet is provided on the heat dissipation casing.

[0009] After the second alignment is completed, the control system drives the centering and cleaning component forward through the first electric slider, so that the first adsorption head on the cleaning component enters the connecting channel. After that, the control system starts the second electric slider, and the second electric slider drives the detection component forward, so that the detection head enters the second adsorption head. At this time, since the detection head that has just been detected is in a high temperature state, the heat conductive ring transfers the temperature to the temperature sensing plate, and the temperature sensing plate bends due to the heat. Several bent temperature sensing plates move the force transmission plate, and the transmission plate drives the control plate to deflect, so that the first air outlet and the second air outlet overlap; when the transmission plate deflects, it drives the transmission piston rod to slide in the compression chamber, and the transmission piston rod squeezes the transmission spring. After the transmission spring is compressed, it bends and transfers the pressure to the extrusion plate at one end. The extrusion plate squeezes the piezoelectric element, and the piezoelectric element generates an electrical signal under pressure, and transmits the electrical signal to the control system; The higher the temperature of the detection head, the greater the deformation of the temperature sensing plate, the greater the deflection angle of the control panel, the larger the corresponding overlapping area of ​​the first air outlet and the second air outlet, and the stronger the electrical signal generated by the piezoelectric element. The control system determines the temperature of the detection head according to the strength of the electrical signal, and makes the heat dissipation motor produce a corresponding speed according to the temperature. The higher the temperature, the greater the speed of the heat dissipation motor. The output shaft of the heat dissipation motor drives the transmission gear to rotate, and the transmission gear drives the heat dissipation ring to rotate through the gear ring. The rotation of the heat dissipation ring drives air to enter the purge chamber from the air inlet, and the airflow passes through the overlap of the first air outlet and the second air outlet and enters the heat dissipation port. After being guided by the heat dissipation port, it blows toward the detection head to achieve the purpose of cooling the detection head.

[0010] When the temperature of the detection head is low, the speed of the heat dissipation motor is low, the airflow velocity generated by the heat dissipation ring is small, and the overlapping area of ​​the first air outlet and the second air outlet is automatically reduced according to the detection temperature, which has a gathering effect on the low-speed airflow to avoid excessive overlap area. When the airflow passes through, it is too dispersed and the detection head cannot be fully purged; When the temperature of the detection head is relatively high, the rotation speed of the cooling motor is high, the air flow velocity generated by the cooling ring is large, and the overlapping area of the first air outlet and the second air outlet automatically increases according to the detected temperature, enabling the high-speed air flow to pass through quickly and purging the detection head over a larger area, thereby improving the cooling efficiency.

[0011] When cooling the detection head, the control system synchronously turns on the dust removal motor, causing the first adsorption head and the second adsorption head to generate negative pressure suction. While the air flow generated by the cooling ring cools down the detection head, it can also blow away the newly contaminated dust on the detection head. Since the end part of the detection head is located inside the second adsorption head, the air flow will be sucked in by the second adsorption head. Synchronously, the first adsorption head cleans the second connection channel, thus achieving synchronous cooling of the detection head and the connection channel. After the temperature of the detection head drops, the deformation of the temperature-sensitive plate gradually recovers, and the overlapping area of the first air outlet and the second air outlet gradually decreases until it is completely closed. The control system turns off the cooling motor, and the cooling is completed. After that, the previous operation is repeated cyclically until all the connection channels of the switch connector have been detected.

[0012] Furthermore, the cooling ring includes a connecting ring, which is rotatably installed inside the cooling housing. A number of cooling fins are installed on the connecting ring, and a toothed ring is installed on the cooling fins. The toothed ring is meshed and driven with a transmission gear.

[0013] Furthermore, a number of second air outlets are provided on the control disk. A number of force transmission plates are provided on the control disk. The force transmission plates are in close contact with the temperature-sensitive plate, and the force transmission plates are connected to the conversion assembly.

[0014] In the normal temperature state, the control disk does not deflect, the control disk and the cooling housing block each other, and the first air outlet and the second air outlet are completely staggered. After the detection is completed, when the control disk deflects, as the control disk deflects, the first air outlet gradually overlaps with the second air outlet. The larger the deflection angle of the control disk, the larger the overlapping area of the first air outlet and the second air outlet, and the larger the available air volume.

[0015] Furthermore, the conversion assembly includes a compression chamber, which is installed on the cooling housing. A piezoelectric element is installed inside the compression chamber. An extrusion plate is slidably installed inside the compression chamber. A transmission piston rod is slidably installed inside the compression chamber. One end of the transmission piston rod is connected to the force transmission plate, and a transmission spring is installed between the transmission piston rod and the extrusion plate.

[0016] Furthermore, the temperature-sensitive plate includes a first heat absorption sheet and a second heat absorption sheet. The first heat absorption sheet is attached to the second heat absorption sheet. Both the first heat absorption sheet and the second heat absorption sheet are installed on the heat conduction ring. Both the first heat absorption sheet and the second heat absorption sheet are made of materials with a high coefficient of thermal expansion. The coefficient of thermal expansion of the first heat absorption sheet is higher than that of the second heat absorption sheet. The second heat absorption sheet is in close contact with the force transmission plate.

[0017] When the temperature-sensitive plate is heated, since the first heat-absorbing fin and the second heat-absorbing fin are made of materials with a high coefficient of thermal expansion, the first heat-absorbing fin and the second heat-absorbing fin absorb heat and deform. Also, because the coefficient of thermal expansion of the first heat-absorbing fin is higher than that of the second heat-absorbing fin, at this time, the first heat-dissipating fin with a larger deformation will bend towards the side of the second heat-dissipating fin. The greater the heat received by the temperature-sensitive plate, the greater the bending degree of the first heat-dissipating fin and the second heat-dissipating fin, and the corresponding overall bending degree of the temperature-sensitive plate also increases.

[0018] Furthermore, the centering and dust-cleaning assembly includes a gantry. At the bottom end of the gantry, first electric sliders are symmetrically installed. The first electric sliders are slidably connected to the machine body. On the gantry, second electric telescopic rods are symmetrically installed. On the output shafts of the second electric telescopic rods, connecting pieces are installed. Between the connecting pieces, a cleaning assembly is installed. On the connecting pieces, first electric telescopic rods are installed. On the output shafts of the first electric telescopic rods, centering blocks are installed.

[0019] The first electric slider is used to drive the entire centering and dust-cleaning assembly to slide on the machine body.

[0020] Place the switch connector to be tested on the electric turntable. The control system activates the electric gripper to clamp and fix the base of the switch connector. The electric turntable drives the switch connector to rotate, so that the connection hole is initially aligned with the detection head. The control system starts the second electric telescopic rod. The output shaft of the second electric telescopic rod drives the cleaning assembly and the first electric telescopic rod to descend through the connecting piece, so that the centering block is at the same horizontal height as the connection hole. Then, start the first electric slider. The first electric slider drives the entire centering and dust-cleaning assembly to move forward, so that the centering block moves to both sides of the connection hole. Then, the control system activates the first electric telescopic rod. The output shaft of the first electric telescopic rod drives the centering block to move and close. The centering block pushes the connection hole to deflect around the central axis of the electric turntable, and finally makes the connection hole located between the two centering blocks, achieving the purpose of precise centering.

[0021] Furthermore, the cleaning assembly includes a dust collection bin. The dust collection bin is installed between the connecting pieces. A negative pressure bin is installed on the dust collection bin. A filter screen is provided at the connection between the dust collection bin and the negative pressure bin. An air dust removal motor is installed in the negative pressure bin. On the output shaft of the air dust removal motor, an air dust removal fan is installed. One end of the dust collection bin is provided with a first adsorption head, and the other end of the dust collection bin is provided with a second adsorption head. Adsorption holes are provided on both the first adsorption head and the second adsorption head.

[0022] The shape of the first adsorption head matches the shape of the connection hole of the switch connector, and the shape of the second adsorption head matches the shape of the detection head. During dust suction, the end part of the connection hole enters the first adsorption head, and the end part of the detection head enters the second adsorption head. There is a gap between the connection hole and the first adsorption head, and there is a gap between the detection end and the second adsorption head.

[0023] After the first centering is completed, the control system controls the first electric telescopic rod to contract and reset. After that, the centering and dust cleaning assembly is driven forward again by the first electric slider, so that the first suction head on the cleaning assembly enters the connecting channel. Then, the dust removal motor is turned on, and the output shaft of the dust removal motor drives the dust removal fan to rotate. The dust removal fan rotates and drives the gas in the negative pressure chamber and the dust collection chamber to flow upward. The air flow out of the negative pressure chamber and the dust collection chamber forms a negative pressure, and the first suction head generates a negative pressure suction force to adsorb the dust in the connecting channel. The dust enters the dust collection chamber through the suction holes on the first suction head, and the filter screen between the dust collection chamber and the negative pressure chamber blocks the dust to prevent it from entering the negative pressure chamber, so as to achieve the purpose of cleaning the switch connector.

[0024] Further, the fixed steering assembly includes an electric turntable rotatably installed on the machine body, and a number of electric grippers are installed on the electric turntable.

[0025] The electric turntable is used to drive the switch connector to rotate at a preset angle; the electric gripper is used to clamp and fix the base of the switch connector.

[0026] After the cleaning is completed, the first electric slider drives the centering and dust cleaning assembly to retreat, and the first suction head is withdrawn from the connecting channel. The output shaft of the second electric telescopic rod drives the cleaning assembly and the first electric telescopic rod to rise and reset. The control system uses the second electric slider to drive the detection assembly to slide, so that the detection head is inserted into the connecting channel. Then, the switch connector is detected through the detection table. After a single connecting channel is detected, the second electric slider drives the detection assembly to retreat, so that the detection head is disengaged from the connecting channel. Then, the electric turntable drives the switch connector to deflect 90°, so that the next connecting channel to be detected is aligned with the detection head. The control system repeats the previous operation to accurately center the second connecting channel.

[0027] Compared with the prior art, the beneficial effects of the present invention are: 1. Utilize the characteristic that the deformation of the temperature-sensitive plate increases with the increase of the temperature of the detection head, so that the overlapping area of the first air outlet and the second air outlet is automatically adjusted according to the detected temperature. When the temperature of the detection head is relatively low, the smaller overlapping area has an aggregating effect on the air flow flowing at a low speed, avoiding the excessive dispersion of the air flow when the overlapping area is too large and unable to blow the detection head comprehensively; when the temperature of the detection head is relatively high, the larger overlapping area allows the high-speed air flow to pass quickly, increasing the blowing area of the detection head and improving the cooling efficiency, achieving the purpose of automatically adjusting the cooling efficiency.

[0028] 2. Use the cleaning assembly to make the first suction head and the second suction head generate a negative pressure suction force to achieve the purpose of synchronously cleaning the detection head and the connecting channel. Through the setting of the dust collection chamber and the filter screen, the collection of dust is achieved. Use the second motor to drive the heat dissipation ring to rotate to generate an air flow, which not only achieves the purpose of cooling the detection head, but also achieves the purpose of blowing and cleaning the detection head.

[0029] 3. The thermal energy of the detection head is converted into mechanical energy through a temperature-sensitive plate, thereby causing the control disk to deflect. The deflection of the control disk drives the displacement of the transmission piston rod, and then the piezoelectric element is pressed to generate an electrical signal, achieving the purpose of detecting the temperature of the detection head.

[0030] 4. The centering blocks arranged symmetrically are used to push the connecting channel to deflect around the central axis of the electric turntable, so that the connecting channel is located between the two centering blocks, achieving the purpose of precise centering and preventing the switch connector from skewing. The switch connector is clamped and fixed by an electric gripper to ensure stability during the detection process. The electric turntable drives the switch connector to realize the turning and preliminary centering of multiple connecting channels. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] As Figures 1 - 12 shown, the present invention provides a technical solution for a conductivity detection device used in the production of switch connectors: including a body 1, a machine cover 4 is rotatably installed on the body 1, a fixed steering component 5 is rotatably installed on the body 1, a centering and dust cleaning component 3 is slidably installed on the body 1, and a detection component 2 is slidably installed on the body 1; the detection component 2 includes a second electric slider 21, a detection table 23 is installed on the second electric slider 21, a detection head 22 is installed on the detection table 23, and a heat dissipation detector 7 is installed on the detection head 22.

The control system evaluates the conductivity of the switch connector according to the measured response parameters, thereby completing the detection. The second electric slider 21 is used to drive the entire detection component 2 to slide on the body 1.

[0036] The centering and dust cleaning assembly 3 includes a gantry 31. At the bottom end of the gantry 31, first electric sliders 32 are symmetrically installed. The first electric sliders 32 are slidably connected to the machine body 1. On the gantry 31, second electric telescopic rods 36 are symmetrically installed.

The first electric sliders 32 are used to drive the entire centering and dust cleaning assembly 3 to slide on the machine body 1.

[0037] The cleaning assembly 6 includes a dust collection bin 61. The dust collection bin 61 is installed between the connecting pieces 33. On the dust collection bin 61, a negative pressure bin 64 is installed. At the connection between the dust collection bin 61 and the negative pressure bin 64, a filter screen is provided. Inside the negative pressure bin 64, a dust removal motor 62 is installed. On the output shaft of the dust removal motor 62, a dust removal fan 63 is installed. At one end of the dust collection bin 61, a first adsorption head 65 is installed. At the other end of the dust collection bin 61, a second adsorption head 66 is installed. Both the first adsorption head 65 and the second adsorption head 66 are provided with adsorption holes.

[0038] The shape of the first adsorption head 65 matches the shape of the connection hole of the switch connector. The shape of the second adsorption head 66 matches the shape of the detection head 22. During dust collection, the end part of the connection hole enters the first adsorption head 65, and the end part of the detection head 22 enters the second adsorption head 66. There is a gap between the connection hole and the first adsorption head 65, and there is a gap between the detection end and the second adsorption head 66.

[0039] The fixed steering assembly 5 includes an electric turntable 51. The electric turntable 51 is rotatably installed on the machine body 1. On the electric turntable 51, a number of electric grippers 52 are installed.

[0040] The electric turntable 51 is used to drive the switch connector to rotate at a preset angle; the electric grippers 52 are used to clamp and fix the base of the switch connector.

[0041] The heat dissipation detector 7 includes a heat dissipation housing 71. The heat dissipation housing 71 is installed on the detection head 22. Inside the heat dissipation housing 71, a heat dissipation ring 72 is rotatably installed. Inside the heat dissipation housing 71, a heat dissipation motor 74 is installed. On the output shaft of the heat dissipation motor 74, a transmission gear 75 is installed. The transmission gear 75 is in meshing transmission with the heat dissipation ring 72. On the heat dissipation housing 71, a control disk 73 is rotatably installed. On the heat dissipation housing 71, a conversion assembly 76 is installed. The conversion assembly 76 is connected to the control disk 73.

[0042] The heat dissipation housing 71 is provided with a heat conduction ring 715. The heat conduction ring 715 is connected to the detection head 22. A temperature sensing plate 716 is installed on the heat conduction ring 715. The temperature sensing plate 716 is in close contact with the control panel 73. The heat dissipation housing 71 is provided with a number of first air outlets 713, a heat dissipation port 711, and a purging chamber 712. The heat dissipation ring 72 is located in the purging chamber 712. The heat dissipation housing 71 is provided with an air inlet 714.

[0043] The heat dissipation ring 72 includes a connecting ring 723 which is rotatably installed in the heat dissipation housing 71. A number of heat dissipation fins 722 are installed on the connecting ring 723. A toothed ring 721 is installed on the heat dissipation fins 722. The toothed ring 721 meshes and drives with the transmission gear 75.

[0044] The control panel 73 is provided with a number of second air outlets 731 and a number of force transmission plates 732. The force transmission plates 732 are in close contact with the temperature sensing plate 716. The force transmission plates 732 are connected to the conversion assembly 76.

[0045] In the normal temperature state, the control panel 73 does not deflect. The control panel 73 and the heat dissipation housing 71 shield each other, and the first air outlet 713 and the second air outlet 731 are completely staggered. After the detection is completed, when the control panel 73 deflects, as the control panel 73 deflects, the first air outlet 713 gradually overlaps with the second air outlet 731. The larger the deflection angle of the control panel 73, the larger the overlapping area of the first air outlet 713 and the second air outlet 731, and the larger the available air volume.

[0046] The conversion assembly 76 includes a compression chamber 761 which is installed on the heat dissipation housing 71. A piezoelectric element 763 is installed in the compression chamber 761. An extrusion plate 764 is slidably installed in the compression chamber 761. A transmission piston rod 765 is slidably installed in the compression chamber 761. One end of the transmission piston rod 765 is connected to the force transmission plate 732. A transmission spring 762 is installed between the transmission piston rod 765 and the extrusion plate 764.

[0047] The temperature sensing plate 716 includes a first heat absorption fin 7161 and a second heat absorption fin 7162. The first heat absorption fin 7161 and the second heat absorption fin 7162 are attached to each other. Both the first heat absorption fin 7161 and the second heat absorption fin 7162 are installed on the heat conduction ring 715. Both the first heat absorption fin 7161 and the second heat absorption fin 7162 are made of a material with a high coefficient of thermal expansion. The coefficient of thermal expansion of the first heat absorption fin 7161 is higher than that of the second heat absorption fin 7162. The second heat absorption fin 7162 is in close contact with the force transmission plate 732.

[0048] When the temperature sensing plate 716 is heated, since the first heat absorbing sheet 7161 and the second heat absorbing sheet 7162 are made of materials with high thermal expansion coefficients, the first heat absorbing sheet 7161 and the second heat absorbing sheet 7162 absorb heat and deform. Also, because the thermal expansion coefficient of the first heat absorbing sheet 7161 is higher than that of the second heat absorbing sheet 7162, at this time, the first heat dissipating sheet 722 with a larger deformation will bend towards the side of the second heat dissipating sheet 722. The greater the heat received by the temperature sensing plate 716, the greater the bending degree of the first heat dissipating sheet 722 and the second heat dissipating sheet 722, and correspondingly, the overall bending degree of the temperature sensing plate 716 also increases.

[0049] Working principle of the present invention: Place the switch connector to be measured on the electric turntable 51. The control system activates the electric gripper 52 to clamp and fix the base of the switch connector. The electric turntable 51 drives the switch connector to rotate, so that the connection hole is initially aligned with the detection head 22. The control system starts the second electric telescopic rod 36. The output shaft of the second electric telescopic rod 36 drives the cleaning assembly 6 and the first electric telescopic rod 34 to descend through the connecting member 33, so that the centering block 35 is at the same horizontal height as the connection hole. Then, start the first electric slider 32. The first electric slider 32 drives the entire centering and dust cleaning assembly 3 to move forward, so that the centering block 35 moves to both sides of the connection hole. Then, the control system activates the first electric telescopic rod 34. The output shaft of the first electric telescopic rod 34 drives the centering block 35 to move and approach. The centering block 35 pushes the connection hole to deflect around the central axis of the electric turntable 51, and finally makes the connection hole located between the two centering blocks 35, achieving the purpose of precise centering.

[0050] After the first centering is completed, the control system controls the first electric telescopic rod 34 to contract and reset. Then, again drive the centering and dust cleaning assembly 3 to move forward through the first electric slider 32, so that the first suction head 65 on the cleaning assembly 6 enters the connection hole. Then, start the dust removal motor 62. The output shaft of the dust removal motor 62 drives the dust removal fan 63 to rotate. The dust removal fan 63 rotates and drives the gas in the negative pressure chamber 64 and the dust collection chamber 61 to flow upward. The air flow in the negative pressure chamber 64 and the dust collection chamber 61 forms a negative pressure. The first suction head 65 generates a negative pressure suction force to adsorb the dust in the connection hole. The dust enters the dust collection chamber 61 through the suction holes on the first suction head 65. The filter screen between the dust collection chamber 61 and the negative pressure chamber 64 blocks the dust to prevent the dust from entering the negative pressure chamber 64, thereby achieving the purpose of cleaning the switch connector.

[0051] After cleaning is completed, the first electric slider 32 drives the centering and cleaning component 3 to withdraw, the first suction head 65 is pulled out of the connection channel, and the output shaft of the second electric telescopic rod 36 drives the cleaning component 6 and the first electric telescopic rod 34 to rise and reset. The control system uses the second electric slider 21 to drive the detection component 2 to slide, so that the detection head 22 is inserted into the connection channel, and then the switch connector is tested through the detection table 23. After the single connection channel is tested, the second electric slider 21 drives the detection component 2 to withdraw, so that the detection head 22 is separated from the connection channel, and then the electric turntable 51 drives the switch connector to deflect 90°, so that the next connection channel to be tested is aligned with the detection head 22, and the control system repeats the previous operation to accurately align the second connection channel.

[0052] After the second centering is completed, the control system drives the centering cleaning component 3 forward through the first electric slider 32, so that the first adsorption head 65 on the cleaning component 6 enters the connecting channel. After that, the control system starts the second electric slider 21, and the second electric slider 21 drives the detection component 2 forward, so that the detection head 22 enters the second adsorption head 66. At this time, since the detection head 22 that has just been detected is in a high temperature state, the heat conductive ring 715 transfers the temperature to the temperature sensing plate 716, and the temperature sensing plate 716 bends due to the heat. Several bent temperature sensing plates 716 move the force transmission plate 732, and the transmission plate drives the control disk 73 to deflect, and the first air outlet 713 and the second air outlet 731 overlap; when the transmission plate deflects, it drives the transmission piston rod 765 to slide in the compression chamber 761, and the transmission piston rod 765 squeezes the transmission spring 762. After the transmission spring 762 is compressed, it bends and transfers the pressure to the extrusion plate 764 at one end, and the extrusion plate 764 squeezes the piezoelectric element 763, and the piezoelectric element 763 is compressed to generate an electrical signal, and the electrical signal is transmitted to the control system; The higher the temperature of the detection head 22, the greater the deformation of the temperature sensing plate 716, the greater the deflection angle of the control disk 73, the greater the corresponding overlapping area of ​​the first air outlet 713 and the second air outlet 731, and the stronger the electrical signal generated by the piezoelectric element 763. The control system determines the temperature of the detection head 22 according to the strength of the electrical signal, and makes the heat dissipation motor 74 produce a corresponding speed according to the temperature. The higher the temperature, the greater the speed of the heat dissipation motor 74. The output shaft of the heat dissipation motor 74 drives the transmission gear 75 to rotate, and the transmission gear 75 drives the heat dissipation ring 72 to rotate through the gear ring 721. The rotation of the heat dissipation ring 72 drives air to enter the purge chamber 712 from the air inlet 714, and the airflow passes through the overlap of the first air outlet 713 and the second air outlet 731 to enter the heat dissipation port 711, and is guided by the heat dissipation port 711 to blow toward the detection head 22, thereby achieving the purpose of cooling the detection head 22.

[0053] When the temperature of the detection head 22 is relatively low, the rotation speed of the heat dissipation motor 74 is relatively low, the air flow velocity generated by the heat dissipation ring 72 is relatively small, and the overlapping area of the first air outlet 713 and the second air outlet 731 automatically decreases according to the detected temperature, generating a gathering effect on the slowly flowing air, avoiding too large an overlapping area and excessive dispersion of the air flow when passing through, and being unable to comprehensively purge the detection head 22; When the temperature of the detection head 22 is relatively high, the rotation speed of the heat dissipation motor 74 is high, the air flow velocity generated by the heat dissipation ring 72 is large, and the overlapping area of the first air outlet 713 and the second air outlet 731 automatically increases according to the detected temperature, enabling the high-speed air flow to pass through quickly and purging the detection head 22 over a larger area, thereby improving the cooling efficiency.

[0054] When dissipating heat from the detection head 22, the control system synchronously turns on the dust removal motor 62 to make the first adsorption head 65 and the second adsorption head 66 generate negative pressure suction. While the air flow generated by the heat dissipation ring 72 cools down the detection head 22, it can also blow away the newly contaminated dust on the detection head 22. Since the end part of the detection head 22 is located inside the second adsorption head 66, the air flow will be sucked in by the second adsorption head 66. Synchronously, the first adsorption head 65 cleans the second connection channel, thereby achieving synchronous heat dissipation for the detection head 22 and the connection channel. After the temperature of the detection head 22 drops, the deformation of the temperature sensing plate 716 gradually recovers, and the overlapping area of the first air outlet 713 and the second air outlet 731 gradually decreases until it is completely closed. The control system turns off the heat dissipation motor 74, and the heat dissipation is completed. After that, the previous operation is repeated cyclically until all the connection channels of the switch connector have been detected.
