Description

Technical Field

[0001] The present invention relates to the technical field of air-conditioning equipment, and in particular to a withstand voltage test contact docking device and an automatic withstand voltage test contact docking system. Background Art

[0002] In the production process of round cabinet air conditioners, when the assembly of the round cabinet internal unit is basically completed, the next step is to use a safety tester to perform a 1000V voltage withstand test on the air conditioner internal unit.

[0003] Currently, the withstand voltage test for air conditioner indoor units is performed manually. During the test, a person holds a withstand voltage test contact and connects it to the cabinet's indoor unit's terminal block. Once connected, the magnet on the contact attaches to the galvanized iron plate behind the terminal block. The person then presses the test button with both hands, and the safety tester begins the air conditioner withstand voltage test. Because the safety tester generates a high voltage of 1000V during the test, this manual connection method poses a risk of electric shock.

[0004] In other words, the conventional method of manually connecting the withstand voltage test contacts has the problem of electric shock risk. Summary of the Invention

[0005] The present invention provides a withstand voltage test contact docking device and an automatic withstand voltage test contact docking system, which are used to solve the problem of electric shock risk in manually docking withstand voltage test contacts.

[0006] The present invention provides a withstand voltage test contact docking device, which includes:

[0007] a linear adjustment assembly having a withstand voltage test contact mounted thereon;

[0008] an arc adjustment assembly on which a linear adjustment assembly is disposed; and

[0009] An axis position adjustment component, on which an arc adjustment component is provided;

[0010] Among them, the axial position adjustment component is used to adjust the central axis D1 of the arc adjustment component so that the central axis D1 coincides with the central axis D2 of the round cabinet air conditioner to be tested. The arc adjustment component is used to adjust the position of the linear adjustment component along its circumference so that the voltage test contact corresponds to the jack of the round cabinet air conditioner terminal board in the first direction. The linear adjustment component is used to insert the voltage test contact into the jack along the first direction.

[0011] In one embodiment, the linear adjustment component includes:

[0012] a cylinder slider connecting plate, which is slidably connected to the arc adjustment assembly; and

[0013] A slide cylinder extending along a first direction and arranged on a cylinder slider connecting plate;

[0014] The telescopic end of the slide cylinder is fixedly connected to the withstand voltage test contact and is used to drive the withstand voltage test contact to telescope in the first direction.

[0015] In the above embodiment, the radial extension and retraction function of the slide cylinder is utilized to control the radial extension and retraction of the withstand voltage test contact. This ensures that the linear adjustment assembly can insert the withstand voltage test contact into the jack of the cabinet air conditioner terminal block along the radial direction of the arc adjustment assembly, and can also remove the withstand voltage test contact from the jack of the cabinet air conditioner terminal block along the radial direction of the arc adjustment assembly.

[0016] In one embodiment, the linear adjustment assembly further includes a precision pressure regulating valve, which is connected to the air inlet of the slide cylinder and is used to adjust the driving pressure of the slide cylinder.

[0017] In this embodiment, the precision pressure-regulating valve adjusts the internal air pressure of the slide cylinder, thereby regulating the slide cylinder's driving pressure to a preset value. This ensures close contact between the withstand voltage test contacts and the cabinet's internal unit terminal block while preventing excessive thrust from the slide cylinder, which could cause the cabinet air conditioner under test to move and affect the accuracy of the withstand voltage test.

[0018] In one embodiment, the arc adjustment assembly includes:

[0019] an arc-shaped fixing plate fixed to the axis position adjustment assembly; and

[0020] An arc-shaped guide rail is provided on the arc-shaped fixing plate and extends along the circumference of the arc-shaped fixing plate, and the cylinder slider connecting plate is slidably connected to the arc-shaped guide rail; and

[0021] The driving mechanism is arranged on the cylinder slider connecting plate and the arc-shaped fixed plate, and the driving mechanism is used to adjust the sliding position of the cylinder slider connecting plate on the arc-shaped guide rail.

[0022] In the above embodiment, the arcuate guide rail provides a guiding function, ensuring that the linear adjustment assembly always moves along the circumferential direction of the arcuate adjustment assembly. The drive mechanism also provides a driving function, driving the linear adjustment assembly to a suitable position to ensure that the withstand voltage test contact aligns with the jack on the cabinet air conditioner terminal board in the first direction. This ensures that the withstand voltage test contact docking device can accurately insert the withstand voltage test contact into the jack.

[0023] In one embodiment, the drive mechanism comprises:

[0024] an arc-shaped rack extending along the circumference of the arc-shaped fixing plate and disposed on the arc-shaped fixing plate and spaced apart from the arc-shaped guide rail in a first direction; and

[0025] a gear meshing with the arc-shaped rack; and

[0026] The driving motor has a fixed cylinder fixed on the cylinder slider connecting plate, and the rotating shaft of the driving motor is connected to the gear. The driving motor is used to drive the gear to rotate.

[0027] In one embodiment, the axis position adjustment assembly includes:

[0028] a fixed frame on which the arc adjustment assembly is fixed; and

[0029] A movable adjustment module connected to the fixed frame;

[0030] The movable adjustment module is used to adjust the position of the central axis D1 so that the central axis D1 coincides with the central axis D2.

[0031] In one embodiment, the mobile adjustment module includes:

[0032] a first adjustment module connected to the fixed frame, the first adjustment module being used to adjust the position of the fixed frame along the y-axis direction; and

[0033] The second adjustment module is connected to the first adjustment module, and is used to adjust the position of the first adjustment module along the x-axis direction.

[0034] In one embodiment, an air-conditioning conveying line assembly is further included, on which the round cabinet air-conditioning to be tested is placed, and the air-conditioning conveying line assembly is used to convey the round cabinet air-conditioning to be tested along a third direction.

[0035] In one embodiment, it also includes an air conditioner in place detection sensor, which is arranged on the air conditioner conveyor line assembly. When the round cabinet air conditioner to be tested is transported to the air conditioner in place detection sensor, the air conditioner in place detection sensor is triggered and the air conditioner conveyor line assembly stops running.

[0036] The present invention provides an automatic docking system for withstand voltage test contacts, which comprises:

[0037] The aforementioned withstand voltage test contact docking device;

[0038] a control assembly connected to the axis position adjustment assembly, the linear adjustment assembly, and the arc adjustment assembly; and

[0039] A visual detection component electrically connected to the control component, the visual detection component is used to monitor the center position and offset angle θ of the circular cabinet air conditioner to be tested, and transmit the current center position information and current offset angle information to the control component;

[0040] Among them, the center position of the circle is the projection point position of the central axis D2 on the first plane P, and the offset angle θ is the angle between the top diagonal hole connecting line L1 of the round cabinet air conditioner to be tested and the edge line L2 of the air conditioner conveying line body assembly on the first plane P. The control component can control the action of the axis position adjustment component according to the current center position information to make the central axis D1 coincide with the central axis D2. The control component can control the action of the arc adjustment component according to the current offset angle information to make the withstand voltage test contact correspond to the jack of the round cabinet air conditioner terminal board in the first direction. The control component can control the action of the linear adjustment component to insert the withstand voltage test contact into the corresponding jack.

[0041] Compared to the prior art, the present invention has the advantage of using an axial position adjustment assembly to adjust the central axis D1 of the arc adjustment assembly so that it coincides with the central axis D2 of the round cabinet air conditioner to be tested. The arc adjustment assembly is then used to adjust the position of the linear adjustment assembly on it so that the withstand voltage test contact aligns with the jack on the round cabinet air conditioner's wiring board in a first direction. Finally, the linear adjustment assembly is used to linearly insert the withstand voltage test contact into the corresponding jack along the first direction. This completes the mechanized docking of the withstand voltage test contact with the round cabinet air conditioner's wiring board. This mechanized docking method replaces the manual docking method used in the prior art, thereby avoiding the risk of electric shock associated with manual docking. This improves the safety of on-site docking of the withstand voltage test contact. Furthermore, the coordinated operation of the withstand voltage test contact docking device, including the linear adjustment assembly, the arc adjustment assembly, and the axial position adjustment assembly, enables quick and accurate docking of the withstand voltage test contact with the round cabinet air conditioner's wiring board. This improves the efficiency of on-site docking of the withstand voltage test contact, thereby enhancing the efficiency of withstand voltage testing of the round cabinet air conditioner, thereby meeting the production requirements of the round cabinet air conditioner.

DETAILED DESCRIPTION

[0053] The present invention will be further described below with reference to the accompanying drawings.

[0054] It should be noted that the withstand voltage test contact docking device in this application is used to dock the withstand voltage test contact 100 with the cabinet air conditioner terminal block 201 of the cabinet air conditioner 200 under test, so that the withstand voltage test of the cabinet air conditioner 200 can be subsequently completed. The first direction in this application is the radial direction of the arc adjustment assembly 20. The linear adjustment assembly 10 can insert the withstand voltage test contact 100 into the jack of the cabinet air conditioner terminal block 201 along the radial direction of the arc adjustment assembly 20. Alternatively, the linear adjustment assembly 10 can remove the withstand voltage test contact 100 from the jack of the cabinet air conditioner terminal block 201 along the radial direction of the arc adjustment assembly 20.

[0055] Example 1

[0056] like Figure 1 As shown, the present invention provides a withstand voltage test contact docking device, which includes a linear adjustment assembly 10, an arc adjustment assembly 20, and an axial position adjustment assembly 30. The linear adjustment assembly 10 has a withstand voltage test contact 100 mounted thereon; the arc adjustment assembly 20 has the linear adjustment assembly 10 mounted thereon; and the axial position adjustment assembly 30 has the arc adjustment assembly 20 mounted thereon. The axial position adjustment assembly 30 is used to adjust the central axis D1 of the arc adjustment assembly 20 so that the central axis D1 coincides with the central axis D2 of the circular cabinet air conditioner 200 to be tested. The arc adjustment assembly 20 is used to adjust the position of the linear adjustment assembly 10 along its circumference so that the withstand voltage test contact 100 corresponds to the jack of the circular cabinet air conditioner terminal board 201 in a first direction. The linear adjustment assembly 10 is used to insert the withstand voltage test contact 100 into the jack along the first direction.

[0057] In the above configuration, the central axis D1 of the arc adjustment assembly 20 is adjusted using the axis position adjustment assembly 30 so that it coincides with the central axis D2 of the round cabinet air conditioner 200 to be tested. The position of the linear adjustment assembly 10 on the arc adjustment assembly 20 is then adjusted so that the withstand voltage test contact 100 aligns with the socket on the round cabinet air conditioner terminal block 201 in a first direction. Finally, the linear adjustment assembly 10 is used to linearly insert the withstand voltage test contact 100 into the corresponding socket along the first direction. This completes the mechanized docking of the withstand voltage test contact 100 with the round cabinet air conditioner terminal block 201. This mechanized docking method replaces the manual docking method used in the prior art, thereby eliminating the risk of electric shock associated with manual docking. This improves the safety of on-site withstand voltage test contact docking operations. Furthermore, the coordinated operation of the withstand voltage test contact docking device, including the linear adjustment assembly 10, the arc adjustment assembly 20, and the axis position adjustment assembly 30, allows for quick and accurate docking of the withstand voltage test contact 100 with the round cabinet air conditioner terminal block 201. This improves the efficiency of on-site connection of the withstand voltage test contacts, thereby improving the efficiency of the withstand voltage test of the cabinet air conditioner, thereby meeting the production requirements of the cabinet air conditioner.

[0058] Specifically, if Figure 2 As shown, in one embodiment, the linear adjustment assembly 10 includes a cylinder slider connecting plate 11 and a slide cylinder 12. The cylinder slider connecting plate 11 is slidably connected to the arc adjustment assembly 20; the slide cylinder 12 is extended and disposed on the cylinder slider connecting plate 11 along a first direction; the extension end of the slide cylinder 12 is fixedly connected to the withstand voltage test contact 100, and is used to drive the withstand voltage test contact 100 to extend and retract in the first direction.

[0059] In the above arrangement, the radial extension and retraction of the withstand voltage test contact 100 is controlled by utilizing the retractable function of the slide cylinder 12. This ensures that the linear adjustment assembly 10 can insert the withstand voltage test contact 100 into the jack of the cabinet air conditioner terminal block 201 along the radial direction of the arc adjustment assembly 20, and can also remove the withstand voltage test contact 100 from the jack of the cabinet air conditioner terminal block 201 along the radial direction of the arc adjustment assembly 20.

[0060] It should be noted that the slide cylinder 12 is connected to an external gas source, and gas is introduced into the slide cylinder 12 through the external gas source, thereby driving the slide cylinder 12 to move.

[0061] Of course, the slide cylinder 12 can be replaced with other types of telescopic parts, such as an electric push rod or a hydraulic cylinder, according to actual conditions.

[0062] Specifically, if Figure 2 As shown, in one embodiment, the linear adjustment assembly 10 further includes a precision pressure regulating valve 13 , which is connected to the air inlet of the slide cylinder 12 for adjusting the driving pressure of the slide cylinder 12 .

[0063] In this configuration, the precision pressure regulating valve 13 adjusts the internal air pressure of the slide cylinder 12, thereby regulating the driving pressure of the slide cylinder 12 to a preset value. This ensures close contact between the withstand voltage test contacts 100 and the cabinet air conditioner terminal block 201 while preventing excessive thrust from the slide cylinder, which could cause the cabinet air conditioner 200 to move and affect the accuracy of the withstand voltage test.

[0064] It should be noted that the precision pressure regulating valve 13 , also called a pressure reducing valve, is a commonly used air pressure regulating device, and the air pressure can be adjusted linearly.

[0065] It should be noted that the thrust of the cylinder is determined by two factors: the cylinder rod diameter and the cylinder air pressure. The cylinder thrust can be adjusted by adjusting the cylinder air pressure.

[0066] Specifically, if Figure 2As shown, in one embodiment, the arc adjustment assembly 20 includes an arc-shaped fixing plate 21, an arc-shaped guide rail 22, and a drive mechanism 23. The arc-shaped fixing plate 21 is fixed to the axis position adjustment assembly 30; the arc-shaped guide rail 22 is provided on the arc-shaped fixing plate 21 along the circumference thereof, and the cylinder slider connecting plate 11 is slidably connected to the arc-shaped guide rail 22; and the drive mechanism 23 is provided on the cylinder slider connecting plate 11 and the arc-shaped fixing plate 21, and is used to adjust the sliding position of the cylinder slider connecting plate 11 on the arc-shaped guide rail 22.

[0067] In the above arrangement, the arcuate guide rail 22 provides a guiding function, ensuring that the linear adjustment assembly 10 always moves along the circumferential direction of the arcuate adjustment assembly 20. The drive mechanism 23 also provides a driving function, driving the linear adjustment assembly 10 to a suitable position to ensure that the withstand voltage test contact 100 aligns with the jack on the cabinet air conditioner terminal block 201 in the first direction. This ensures that the withstand voltage test contact docking device can accurately insert the withstand voltage test contact 100 into the jack.

[0068] Specifically, if Figure 2 As shown, in one embodiment, the driving mechanism 23 includes an arcuate rack 231, a gear 232, and a driving motor 233. The arcuate rack 231 is provided on the arcuate fixing plate 21 along the circumference of the arcuate fixing plate 21 and is spaced apart from the arcuate guide rail 22 in the first direction; the gear 232 is meshed with the arcuate rack 231; and the driving motor 233 has a fixed cylinder fixed to the cylinder slider connecting plate 11, and a rotating shaft of the driving motor 233 is connected to the gear 232. The driving motor 233 is used to drive the gear 232 to rotate.

[0069] Specifically, if Figure 2 As shown, in one embodiment, the driving motor 233 is a servo motor.

[0070] Specifically, if Figure 3 As shown, in one embodiment, the axis position adjustment assembly 30 includes a fixed frame 31 and a movable adjustment module 32. The fixed frame 31 has the arc adjustment assembly 20 fixed thereto, and the movable adjustment module 32 is connected to the fixed frame 31. The movable adjustment module 32 is used to adjust the position of the central axis D1 so that the central axis D1 coincides with the central axis D2.

[0071] Specifically, if Figure 3As shown, in one embodiment, the movable adjustment module 32 includes a first adjustment module 321 and a second adjustment module 322. The first adjustment module 321 is connected to the fixed frame 31 and is used to adjust the position of the fixed frame 31 along the y-axis direction; the second adjustment module 322 is connected to the first adjustment module 321 and is used to adjust the position of the first adjustment module 321 along the x-axis direction.

[0072] Specifically, if Figure 3 As shown, in one embodiment, the fixing frame 31 is a U-shaped profile frame.

[0073] Specifically, if Figure 3 As shown, in one embodiment, the first adjustment module 321 includes a longitudinal fixed plate 3211, a longitudinal linear bearing 3212, a longitudinal movable guide shaft 3213, a guide shaft support 3214, a guide shaft support fixing plate 3215, a longitudinal electric cylinder 3216, a floating joint 3217 and a floating joint connecting plate 3218.

[0074] Specifically, if Figure 3 As shown, in one embodiment, the longitudinal fixed plate 3211 is fixed on the second adjustment module 322, and the fixed cylinder of the longitudinal electric cylinder 3216 is extended along the y-axis direction and is set on the longitudinal fixed plate 3211, and its drive shaft is connected to the floating joint 3217, and the floating joint 3217 is connected to the floating joint connecting plate 3218, and the floating joint connecting plate 3218 is connected to the U-shaped profile frame.

[0075] Specifically, if Figure 3 As shown, in one embodiment, there are four longitudinal linear bearings 3212, divided into two groups and fixed to the guide shaft support fixing plate 3215. Each group of longitudinal linear bearings is respectively arranged on both sides of the longitudinal electric cylinder 3216 along the x-axis direction and is symmetrically arranged relative to the center of the longitudinal electric cylinder 3216. The two longitudinal linear bearings 3212 in each group are spaced apart along the y-axis direction. There are two longitudinal movable guide shafts 3213, each of which is inserted into the two groups of longitudinal linear bearings. One end of the longitudinal movable guide shaft 3213 is connected to the guide shaft support 3214, which is connected to the guide shaft support fixing plate 3215, which is connected to the U-shaped profile frame.

[0076] It should be noted that the longitudinal linear bearing 3212 ensures that the corresponding longitudinal movable guide shaft 3213 moves along the Y-axis. The longitudinal movable guide shaft 3213 moves within the internal hole of the longitudinal linear bearing 3212. When the longitudinal electric cylinder 3216 is actuated, it drives the U-shaped profile frame forward or backward. The longitudinal linear bearing 3212 ensures that the U-shaped profile frame can translate along the Y-axis. The floating joint 3217 prevents the drive shaft of the longitudinal electric cylinder 3216 from being misaligned with the floating joint connecting plate 3218, which could cause the U-shaped profile frame to move unsmoothly. This effectively reduces the difficulty of debugging the axis position adjustment assembly 30.

[0077] Specifically, if Figure 4 As shown, in one embodiment, the second adjustment module 322 includes a base 3221, a slide 3222, and a drive structure, which is used to drive the slide 3222 to slide on the base 3221. The drive structure includes a rotary motor 3223 and a ball screw mechanism (existing technology, not described in detail here). The rotary motor 3223 can drive the ball screw located in the base 3221 to rotate, thereby moving the ball screw nut that cooperates with the ball screw, thereby driving the slide 3222 to slide. The first adjustment module is fixed to the slide 3222.

[0078] Specifically, if Figure 3 As shown, in one embodiment, the axis position adjustment assembly 30 further includes a support foot 331 and a support frame 332. The upper end of the support frame 332 is provided with a second adjustment module 322, and the lower end of the support frame 332 is provided with a support foot 331.

[0079] Specifically, if Figure 3 As shown, in one embodiment, the support frame 332 is a square frame.

[0080] Specifically, if Figure 5 As shown, in one embodiment, the voltage resistance test contact docking device also includes an air-conditioning conveying line assembly 40, and the circular cabinet air-conditioning 200 to be tested is placed on the air-conditioning conveying line assembly 40, and the air-conditioning conveying line assembly 40 is used to convey the circular cabinet air-conditioning 200 to be tested along a third direction (the length direction of the air-conditioning conveying line assembly 40).

[0081] Specifically, if Figure 5 As shown, in one embodiment, the air conditioner conveying line assembly 40 includes an air conditioner conveying chain plate line 41, which is used to continuously convey the round cabinet air conditioner 200 to be tested.

[0082] Specifically, if Figure 1 As shown, in one embodiment, a rectangular plate is integrated on the support frame 332, and the second adjustment module 322 is set on the rectangular plate. The side wall where the long side of the rectangular plate is located is in contact with the long side wall of the air-conditioning conveyor chain plate line 41.

[0083] Specifically, if Figure 1 and Figure 5 As shown, in one embodiment, the voltage-resistant test contact docking device also includes an air-conditioning in-place detection sensor 50, which is arranged on the air-conditioning conveying line assembly 40. When the round cabinet air-conditioning 200 to be tested is transported to the air-conditioning in-place detection sensor 50, the air-conditioning in-place detection sensor 50 is triggered and the air-conditioning conveying line assembly 40 stops running.

[0084] Example 2

[0085] like Figure 6 As shown, the present invention provides an automatic docking system for withstand voltage test contacts. The automatic docking system includes a withstand voltage test contact docking device, a control component, and a visual inspection component 60. The control component is connected to the axis position adjustment component 30, the linear adjustment component 10, and the arc adjustment component 20. The visual inspection component 60 is electrically connected to the control component. The visual inspection component 60 is used to monitor the center position and offset angle θ of the circular cabinet air conditioner 200 under test and transmit the current center position information and the current offset angle information to the control component. The control component can control the axis position adjustment component 30 based on the current center position information to align the center axis D1 with the center axis D2. The control component can control the arc adjustment component 20 based on the current offset angle information to align the withstand voltage test contact 100 with the jack of the circular cabinet air conditioner terminal board 201 in a first direction. The control component can control the linear adjustment component 10 to insert the withstand voltage test contact 100 into the corresponding jack.

[0086] It should be noted that if Figure 5 As shown, the center position of the circle is the projection point position of the central axis D2 on the first plane P, the offset angle θ is the angle between the top diagonal hole connection line L1 of the circular cabinet air conditioner 200 to be tested and the edge line L2 of the air conditioner conveying line assembly 40 on the first plane P, and L1' is a straight line parallel to L1 and located on the first plane P.

[0087] In the above configuration, the control component controls the axis position adjustment component 30 to adjust the central axis D1 of the arc adjustment component 20 so that it coincides with the central axis D2 of the round cabinet air conditioner 200 to be tested. The control component controls the arc adjustment component 20 to adjust its position on the linear adjustment component 10 so that the withstand voltage test contact 100 corresponds to the socket on the round cabinet air conditioner terminal board 201 in a first direction. Finally, the control component controls the linear adjustment component 10 to insert the withstand voltage test contact 100 into the corresponding socket in a straight line along the first direction. This completes the automated docking of the withstand voltage test contact 100 and the round cabinet air conditioner terminal board 201. This automated docking method can replace the manual docking method used in the prior art. This avoids the risk of electric shock caused by manual docking. This in turn improves the safety of on-site docking operations for the withstand voltage test contacts.

[0088] Furthermore, the control assembly controls the coordinated operation of the withstand voltage test contact docking device, including the linear adjustment assembly 10, the arc adjustment assembly 20, and the axis position adjustment assembly 30, enabling rapid and accurate docking of the withstand voltage test contact 100 with the cabinet air conditioner terminal block 201. This improves the efficiency of on-site withstand voltage test contact docking operations, thereby enhancing the efficiency of withstand voltage testing of cabinet air conditioners, thereby meeting the production requirements of cabinet air conditioners.

[0089] In addition, the automatic connection system for the withstand voltage test contacts has a high degree of automation, accurate and fast connection, which can avoid the problem of missing the round cabinet air conditioner 200 to be tested due to the high transportation efficiency of the air conditioner conveyor chain plate line 41.

[0090] Specifically, if Figure 1 As shown, in one embodiment, a withstand voltage test contact docking device includes a linear adjustment assembly 10, an arc adjustment assembly 20, and an axial position adjustment assembly 30. The linear adjustment assembly 10 has the withstand voltage test contact 100 mounted thereon; the arc adjustment assembly 20 has the linear adjustment assembly 10 mounted thereon; and the axial position adjustment assembly 30 has the arc adjustment assembly 20 mounted thereon. The axial position adjustment assembly 30 is used to adjust the central axis D1 of the arc adjustment assembly 20 so that the central axis D1 coincides with the central axis D2 of the circular cabinet air conditioner 200 to be tested. The arc adjustment assembly 20 is used to adjust the position of the linear adjustment assembly 10 along its circumference so that the withstand voltage test contact 100 corresponds to the jack of the circular cabinet air conditioner terminal board 201 in a first direction. The linear adjustment assembly 10 is used to insert the withstand voltage test contact 100 into the jack along the first direction.

[0091] Specifically, if Figure 1As shown, in one embodiment, the linear adjustment assembly 10 includes a cylinder slider connecting plate 11 and a slide cylinder 12. The cylinder slider connecting plate 11 is slidably connected to the arc adjustment assembly 20; the slide cylinder 12 is extended and disposed on the cylinder slider connecting plate 11 along a first direction; the extension end of the slide cylinder 12 is fixedly connected to the withstand voltage test contact 100, and is used to drive the withstand voltage test contact 100 to extend and retract in the first direction.

[0092] In the above arrangement, the radial extension and retraction of the withstand voltage test contact 100 is controlled by utilizing the retractable function of the slide cylinder 12. This ensures that the linear adjustment assembly 10 can insert the withstand voltage test contact 100 into the jack of the cabinet air conditioner terminal block 201 along the radial direction of the arc adjustment assembly 20, and can also remove the withstand voltage test contact 100 from the jack of the cabinet air conditioner terminal block 201 along the radial direction of the arc adjustment assembly 20.

[0093] It should be noted that the slide cylinder 12 is connected to an external gas source, and gas is introduced into the slide cylinder 12 through the external gas source, thereby driving the slide cylinder 12 to move.

[0094] Of course, the slide cylinder 12 can be replaced with other types of telescopic parts, such as an electric push rod or a hydraulic cylinder, according to actual conditions.

[0095] Specifically, if Figure 2 As shown, in one embodiment, the linear adjustment assembly 10 further includes a precision pressure regulating valve 13, which is connected to the air inlet of the slide cylinder 12 and is used to adjust the driving pressure of the slide cylinder 12. The precision pressure regulating valve 13 can adjust the internal air pressure of the slide cylinder 12, thereby adjusting the driving pressure of the slide cylinder 12 to a preset pressure value. This ensures that the withstand voltage test contact 100 is in close contact with the cabinet air conditioner terminal board 201 while preventing the cabinet air conditioner 200 from moving due to excessive thrust from the slide cylinder, thereby affecting the accuracy of the withstand voltage test.

[0096] It should be noted that the precision pressure regulating valve 13 , also called a pressure reducing valve, is a commonly used air pressure regulating device, and the air pressure can be adjusted linearly.

[0097] It should be noted that the thrust of the cylinder is determined by two factors: the cylinder rod diameter and the cylinder air pressure. The cylinder thrust can be adjusted by adjusting the cylinder air pressure.

[0098] Specifically, if Figure 2As shown, in one embodiment, the arc adjustment assembly 20 includes an arc-shaped fixing plate 21, an arc-shaped guide rail 22, and a drive mechanism 23. The arc-shaped fixing plate 21 is fixed to the axis position adjustment assembly 30; the arc-shaped guide rail 22 is provided on the arc-shaped fixing plate 21 along its circumference, and the cylinder slider connecting plate 11 is slidably connected to the arc-shaped guide rail 22; and the drive mechanism 23 is provided on the cylinder slider connecting plate 11 and the arc-shaped fixing plate 21. The drive mechanism 23 is used to adjust the sliding position of the cylinder slider connecting plate 11 on the arc-shaped guide rail 22. The arc-shaped guide rail 22 provides a guiding function, ensuring that the linear adjustment assembly 10 always moves along the circumference of the arc adjustment assembly 20. The drive mechanism 23 also provides a driving function, driving the linear adjustment assembly 10 to a suitable position to ensure that the withstand voltage test contact 100 corresponds to the jack on the cabinet air conditioner terminal block 201 in the first direction. This ensures that the withstand voltage test contact docking device can accurately insert the withstand voltage test contact 100 into the jack.

[0099] Specifically, if Figure 2 As shown, in one embodiment, the driving mechanism 23 includes an arcuate rack 231, a gear 232, and a driving motor 233. The arcuate rack 231 is provided on the arcuate fixing plate 21 along the circumference of the arcuate fixing plate 21 and is spaced apart from the arcuate guide rail 22 in the first direction; the gear 232 is meshed with the arcuate rack 231; and the driving motor 233 has a fixed cylinder fixed to the cylinder slider connecting plate 11, and a rotating shaft of the driving motor 233 is connected to the gear 232. The driving motor 233 is used to drive the gear 232 to rotate.

[0100] Specifically, if Figure 2 As shown, in one embodiment, the driving motor 233 is a servo motor.

[0101] Specifically, if Figure 3 As shown, in one embodiment, the axis position adjustment assembly 30 includes a fixed frame 31 and a movable adjustment module 32. The fixed frame 31 has the arc adjustment assembly 20 fixed thereto, and the movable adjustment module 32 is connected to the fixed frame 31. The movable adjustment module 32 is used to adjust the position of the central axis D1 so that the central axis D1 coincides with the central axis D2.

[0102] Specifically, if Figure 3 As shown, in one embodiment, the movable adjustment module 32 includes a first adjustment module 321 and a second adjustment module 322. The first adjustment module 321 is connected to the fixed frame 31 and is used to adjust the position of the fixed frame 31 along the y-axis direction; the second adjustment module 322 is connected to the first adjustment module 321 and is used to adjust the position of the first adjustment module 321 along the x-axis direction.

[0103] Specifically, if Figure 3 As shown, in one embodiment, the fixing frame 31 is a U-shaped profile frame.

[0104] Specifically, if Figure 3 As shown, in one embodiment, the first adjustment module 321 includes a longitudinal fixed plate 3211, a longitudinal linear bearing 3212, a longitudinal movable guide shaft 3213, a guide shaft support 3214, a guide shaft support fixing plate 3215, a longitudinal electric cylinder 3216, a floating joint 3217 and a floating joint connecting plate 3218.

[0105] Specifically, if Figure 3 As shown, in one embodiment, the longitudinal fixed plate 3211 is fixed on the second adjustment module 322, and the fixed cylinder of the longitudinal electric cylinder 3216 is extended along the y-axis direction and is set on the longitudinal fixed plate 3211, and its drive shaft is connected to the floating joint 3217, and the floating joint 3217 is connected to the floating joint connecting plate 3218, and the floating joint connecting plate 3218 is connected to the U-shaped profile frame.

[0106] Specifically, if Figure 3 As shown, in one embodiment, there are four longitudinal linear bearings 3212, divided into two groups and fixed to the guide shaft support fixing plate 3215. Each group of longitudinal linear bearings is respectively arranged on both sides of the longitudinal electric cylinder 3216 along the x-axis direction and is symmetrically arranged relative to the center of the longitudinal electric cylinder 3216. The two longitudinal linear bearings 3212 in each group are spaced apart along the y-axis direction. There are two longitudinal movable guide shafts 3213, each of which is inserted into the two groups of longitudinal linear bearings. One end of the longitudinal movable guide shaft 3213 is connected to the guide shaft support 3214, which is connected to the guide shaft support fixing plate 3215, which is connected to the U-shaped profile frame.

[0107] It should be noted that the longitudinal linear bearing 3212 ensures that the corresponding longitudinal movable guide shaft 3213 moves along the Y-axis. The longitudinal movable guide shaft 3213 moves within the internal hole of the longitudinal linear bearing 3212. When the longitudinal electric cylinder 3216 is actuated, it drives the U-shaped profile frame forward or backward. The longitudinal linear bearing 3212 ensures that the U-shaped profile frame can translate along the Y-axis. The floating joint 3217 prevents the drive shaft of the longitudinal electric cylinder 3216 from being misaligned with the floating joint connecting plate 3218, which could cause the U-shaped profile frame to move unsmoothly. This effectively reduces the difficulty of debugging the axis position adjustment assembly 30.

[0108] Specifically, if Figure 3As shown, in one embodiment, the axis position adjustment assembly 30 further includes a support foot 331 and a support frame 332. The upper end of the support frame 332 is provided with a second adjustment module 322, and the lower end of the support frame 332 is provided with a support foot 331.

[0109] Specifically, if Figure 3 As shown, in one embodiment, the support frame 332 is a square frame.

[0110] Specifically, if Figure 5 As shown, in one embodiment, the voltage withstand test contact docking device also includes an air conditioning conveying line assembly 40, and the circular cabinet air conditioner 200 to be tested is placed on the air conditioning conveying line assembly 40, and the air conditioning conveying line assembly 40 is used to convey the circular cabinet air conditioner 200 to be tested along a third direction.

[0111] Specifically, if Figure 5 As shown, in one embodiment, the air conditioner conveying line assembly 40 includes an air conditioner conveying chain plate line 41, which is used to continuously convey the round cabinet air conditioner 200 to be tested.

[0112] Specifically, if Figure 1 and Figure 5 As shown, in one embodiment, a rectangular plate is integrated on the support frame 332, and the second adjustment module 322 is set on the rectangular plate. The side wall where the long side of the rectangular plate is located is in contact with the long side wall of the air-conditioning conveyor chain plate line 41.

[0113] Specifically, if Figure 5 As shown, in one embodiment, the voltage-resistant test contact docking device also includes an air-conditioning in-place detection sensor 50, which is arranged on the air-conditioning conveying line assembly 40. When the round cabinet air-conditioning 200 to be tested is transported to the air-conditioning in-place detection sensor 50, the air-conditioning in-place detection sensor 50 is triggered and the air-conditioning conveying line assembly 40 stops running.

[0114] It should be noted that the air conditioner arrival detection sensors 50 are through-beam sensors, one on each side of the air conditioner conveyor assembly 40, one of which is a transmitter and the other is a receiver. When powered on, the transmitter emits light to the receiver, which then reflects the light back to the transmitter. When the light emitted by the transmitter is reflected back, there is no obstruction between the two through-beam sensors. If the light emitted by the transmitter is not reflected back to the transmitter, it is determined that the air conditioner has reached the sensor's beam position. At this point, the visual detection assembly 60 begins detection.

[0115] Specifically, if Figure 7As shown, in one embodiment, the visual inspection component 60 includes a visual inspection component column frame 61, a visual inspection camera 62, a visual inspection lens 63, and a visual inspection light source 64. The visual inspection camera 62, the visual inspection lens 63, and the visual inspection light source 64 are disposed on the visual inspection component column frame 61. A U-shaped support leg is disposed at the bottom of the visual inspection component column frame 61 and is mounted above the air conditioner conveyor chain plate line 41. The visual inspection camera 62, the visual inspection lens 63, and the visual inspection light source 64 are located on top of the round cabinet air conditioner 200 to be tested.

[0116] It should be noted that the visual inspection light source 64 illuminates the inspected material to make the features of the inspected object more obvious. The visual inspection lens 63 can adjust the focal length of the imaging of the visual inspection camera 62, thereby presenting a clearer image of the object in the visual inspection camera 62.

[0117] The working principle of the visual inspection component can be divided into the following main steps:

[0118] 1. Image acquisition:

[0119] Industrial cameras use optical lenses to focus the image of the target object onto an image sensor. Common sensors include CCD (charge-coupled device) and CMOS (complementary metal oxide semiconductor).

[0120] CCD sensors are known for their high sensitivity and blooming resistance, making them suitable for applications requiring high precision.

[0121] CMOS sensors have the characteristics of low power consumption and high integration, and are suitable for high-speed image processing needs.

[0122] Second, signal conversion and amplification:

[0123] After the image sensor converts the optical signal into an electrical signal, it will perform necessary amplification and adjustment to ensure signal quality and adapt to subsequent processing requirements.

[0124] 3. Analog-to-digital conversion (ADC):

[0125] The amplified analog electrical signal is converted into a digital signal, which facilitates subsequent digital processing. High-precision ADC can improve the clarity and accuracy of the image.

[0126] IV. Image processing and analysis:

[0127] Industrial cameras are typically equipped with a dedicated DSP (digital signal processor) or embedded computer to execute complex image processing algorithms.

[0128] Common image processing includes edge detection, threshold segmentation, shape recognition, barcode recognition, etc. These functions help to achieve automated quality inspection and fault diagnosis.

[0129] 5. Data storage and transmission:

[0130] The processed image data can be stored in local memory or transmitted in real time to external devices such as industrial control computers or network servers via high-speed interfaces (such as USB3.0, GigE Vision, CoaXPress, etc.).

[0131] Real-time transmission and processing of data is crucial for efficient production line monitoring, ensuring timely responses and adjustments.

[0132] It should be noted that the visual detection component 60 can realize visual photography and recognition of the center position and offset angle θ of the circular cabinet air conditioner 200 to be tested and transmit the current center position information and current offset angle information to the control component.

[0133] The following describes the operation process of the automatic connection system for withstand voltage test contacts in this embodiment:

[0134] 1. The visual inspection assembly 60 identifies the three adjacent circular holes on the upper edge of the curved guide rail 22 and uses an algorithm to determine the center position (X0, Y0) of the curved guide rail 22, which is also the center position of the arc adjustment assembly 20. It should be noted that during operation of the automatic docking system for the withstand voltage test contacts, this center position is aligned with the center position of the circular cabinet air conditioner 200 under test.

[0135] 2. Test: When the withstand voltage test contact 100 on the linear adjustment assembly 10 rotates 1° along the arc radius of the curved guide rail 22, the servo motor rotates N0 revolutions. Adjust the pressure of the precision pressure regulating valve 13 on the linear adjustment assembly 10 to ensure close contact between the withstand voltage test contact 100 and the cabinet air conditioner terminal board 201 while preventing excessive thrust from the slide cylinder, which could cause the cabinet air conditioner 200 to move and affect test accuracy.

[0136] It should be noted that the N0 value is obtained through control software monitoring during debugging. After the visual inspection component 60 identifies the position of the round cabinet air conditioner under test, it provides feedback on the rotation angle of the round cabinet air conditioner. Therefore, directly obtaining this N0 value during testing reduces real-time data processing and speeds up information processing.

[0137] It should be noted that during the project testing phase, the proportional relationship between the rotation angle and the number of rotations of the servo motor is determined. Therefore, in actual application, when the rotation angle is known, the number of rotations of the servo motor can be calculated based on the proportional relationship.

[0138] 3. After clicking the Machine Initialization button, the slide cylinder 12 on the linear adjustment assembly 10 retracts, the longitudinal electric cylinder 3216 of the axis position adjustment assembly 30 retracts, and the second adjustment module 322 moves horizontally to the module origin. Simultaneously, the servo motor of the arc adjustment assembly 20 activates, driving the gear to rotate, meshing with the arc rack 231 to its limit position, then moving in the opposite direction to the center of the assembly. The automatic docking device is now initialized.

[0139] It should be noted that this position (the middle position) is chosen because the air conditioner is usually in the middle position with a small deviation angle. Therefore, it is more convenient to set the initialization position in the middle position.

[0140] 4. The air conditioner conveyor chain plate line 41 moves, carrying the round cabinet air conditioner 200 to be tested. When the round cabinet air conditioner 200 to be tested runs to the air conditioner in place detection beam sensor 50, the air conditioner in place detection beam sensor 50 is triggered, and the air conditioner conveyor chain plate line 41 stops running.

[0141] 5. The visual inspection component 60 photographs the top of the circular cabinet air conditioner under test and determines the current position and deflection angle of the air conditioner by identifying the fixing holes and edge features of the top portion. Because the lines connecting the two diagonal holes of the four fixing holes at the top of the circular cabinet air conditioner are perpendicular to each other and have different lengths, this feature recognition allows the construction of a mathematical model and algorithm to analyze the current center position (X1, Y1) of the circular cabinet air conditioner and the rotation angle between the connecting line of the diagonal holes and the edge of the air conditioner's conveyor chain, i.e., the offset angle θ.

[0142] It should be noted that when the visual inspection component is debugged, a visual inspection template will be established, and the air conditioner in this template will be manually aligned parallel to the edge of the conveying component (air conditioner conveying line component 40). At this time, θ = 0. The top cover has four circular fixing holes. The focus of the line connecting the four holes is the center position of the air conditioner. The line connecting the two edges of the two fixing holes (located on L1) is a line parallel to the edge of the conveying component. This line is shorter and parallel to the top edge. The line connecting the two holes near the top edge is perpendicular to the edge of the conveying component.

[0143] It should be noted that the intersection of the two lines is the current center position of the air conditioner (X1, Y1), and the angle between the line connecting the fixing holes between the two edges and the template L1 (parallel to the edge of the conveying component) is the offset angle θ.

[0144] 6. When the current center position (X1, Y1) and offset angle θ of the circular cabinet air conditioner 200 under test are identified by the visual inspection assembly 60, the second adjustment module 322 in the axis position adjustment assembly 30 operates (X1-X0), while the longitudinal electric cylinder 3216 operates (Y1-Y0), aligning the center of the arc adjustment assembly 20 with the current center of the circular cabinet air conditioner 200 under test. Simultaneously, the servo motor operates, driving the gear to rotate, thereby meshing with the arc rack 231. The operating angle is equal to the current offset angle θ of the circular cabinet air conditioner 200 under test, i.e., the servo motor rotates N0 × θ revolutions. After the servo motor completes its rotation, the slide cylinder 12 extends to connect with the circular cabinet air conditioner terminal board 201 for testing. After the test is complete, the slide cylinder 12 retracts, the longitudinal electric cylinder 3216 retracts, and the second adjustment module 322 simultaneously returns to its initial position.

[0145] It should be noted that the installation surface of the round cabinet air conditioner wiring board 201 is Figure 5 The L1 line is parallel, and the withstand voltage test contact 100 is perpendicular to the L1 line. After rotating a certain angle, the two are still perpendicular, so the deflection angles of the two are the same (see Figure 8 ).

[0146] 7. At this point, the withstand voltage test contact automatic docking system completes the docking test of the round cabinet air conditioner 200 to be tested, and the round cabinet air conditioner 200 to be tested enters the next process, and the next cycle of automatic docking test is carried out after the next round cabinet air conditioner to be tested triggers the air conditioner in place detection matching sensor 50.

In particular, the various technical features described in the various embodiments may be combined in any manner, provided no structural conflicts exist.
