[0002] At present, the domestic compressor industry mainly uses manual detection for the short-circuit detection of the entire compressor turn-to-turn. During the detection process, the inspector needs to connect the electric plug to the terminal of each compressor and then start the detection. The electric plug of some compressors is difficult to insert, and the inspector needs to repeat the operation many times, resulting in a large workload and low efficiency.

A laser sensor is installed on the main frame. The loading and unloading mechanism includes a jaw lifting cylinder, a jaw lifting plate, a jaw mounting plate, a jaw, a jaw cylinder and a jaw rotating mechanism.

[0060] Embodiment 1

[0061] At present, the domestic compressor industry mainly uses manual detection for the short-circuit detection of the entire compressor turn-to-turn. During the detection process, the inspector needs to connect the electric plug to the terminal of each compressor and then start the detection. The electric plug of some compressors is difficult to insert, and the inspector needs to repeat the operation many times, which results in a large workload and low efficiency. The existing technology cannot combine the positioning pins and claws to accurately position the compressor for a second time, so it is impossible to realize the automatic plugging and unplugging of the terminal, resulting in a large workload for personnel. Therefore, it is necessary to solve the problem of how to accurately position the compressor at the detection position to realize the automatic plugging and unplugging of the terminal for automatic detection.

[0062] In response to the above problems, an embodiment of the present application provides an automatic detection device for compressor inter-turn short circuit, which can accurately position the compressor at the detection position, realize automatic plug-in and unplugging of terminal blocks for automatic detection, and improve the efficiency of compressor inter-turn short circuit detection.

[0063] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0064] See also Figure 1 , Figure 2 and Fig.10 The first embodiment of the automatic detection device for short circuit between turns of a compressor shown in the embodiment of the present application includes:

[0065] The positioning tooling plate 1, the positioning claw assembly 2, the probe assembly 3 and the photoelectric sensor 4, wherein the positioning tooling plate 1 is provided with a positioning pin, the positioning pin includes a first positioning pin 11, and the first positioning pin 11 is used to cooperate with the triangular bracket of the compressor for positioning. It can be understood that, if Fig.10 As shown, the first positioning pin 11 can be inserted into the limiting hole at the triangular apex of the compressor triangular bracket to complete the positioning, or the triangular bracket of the compressor can be limited by other methods to achieve positioning, which depends on the actual application situation and is not the only limitation here.

[0066] The photoelectric sensor 4 is arranged at the detection station. When the positioning tooling plate 1 is located between the transmitting end and the receiving end of the photoelectric sensor 4, the photoelectric sensor 4 can output an in-position signal of the positioning tooling plate 1 to determine that the positioning tooling plate 1 runs to the detection station. That is, when the photoelectric sensor 4 detects that the positioning tooling plate 1 runs to the detection station, the in-position signal can guide the positioning claw assembly 2 to clamp and position the compressor.

[0067] In the embodiment of the present application, the positioning claw assembly 2 includes but is not limited to a first claw assembly 21 and a second claw assembly 22. The first claw assembly 21 and the second claw assembly 22 are respectively arranged on both sides of the detection station, so that when the first claw assembly 21 and the second claw assembly 22 are close to each other, the compressor 7 can be clamped between the first claw assembly 21 and the second claw assembly 22, thereby completing the positioning of the compressor 7.

[0068] After the compressor 7 is positioned, the probe assembly 3 is connected to the terminals of the compressor 7 for detecting the short circuit between turns of the compressor 7. The terminals of the compressor 7 are generally arranged on the top of the compressor housing. Therefore, if this is the case, the probe assembly 3 can be connected to the terminals of the compressor 7 in the vertical direction from top to bottom, thereby improving the efficiency of the connection and reducing the difficulty of plugging and unplugging the probe assembly 3 during the connection. It is understandable that the terminal of the compressor 7 can be set in various positions. In practical applications, the connection direction of the probe assembly 3 needs to be determined according to the setting position of the terminal of the compressor 7, and is not limited here.

[0069] From the above embodiment 1, the following beneficial effects can be seen:

[0070] The bracket of the compressor is positioned by the positioning pins on the positioning tooling plate. When the photoelectric sensor arranged at the detection station detects that the positioning tooling plate has moved to the detection station, the first clamping claw assembly and the second clamping claw assembly clamp and position the compressor at the detection station, and the probe assembly is accurately connected to the terminal of the compressor to perform turn-to-turn short-circuit detection on the compressor, thereby improving the efficiency of the compressor turn-to-turn short-circuit detection and avoiding the need for detection personnel to repeat wiring operations, thereby effectively improving the production efficiency and production quality of the compressor.

[0071] Embodiment 2

[0072] For ease of understanding, an embodiment of an automatic detection device for compressor inter-turn short circuit is provided below for illustration. In actual application, the probe assembly will have a detection plug part, a docking cylinder and an angle adjustment mechanism, so that the probe assembly can be flexibly connected to the terminal of the compressor, thereby improving the connection efficiency and reducing the repeated plugging and unplugging of the probe.

[0073] See also Figure 1 and Figure 3The second embodiment of the automatic detection device for short circuit between turns of a compressor shown in the embodiment of the present application includes:

[0074] The probe assembly 3 is connected to the terminal of the compressor 7 and is used to perform turn-to-turn short circuit detection on the compressor 7. The probe assembly 3 includes but is not limited to a detection plug part 31, a docking cylinder 32, and an angle adjustment mechanism 33. The docking cylinder 32 is a cylinder used to dock the detection plug part 31 with the terminal of the compressor 7. The pneumatic action of the cylinder imparts pneumatic force to the docking of the detection plug part 31 with the terminal, eliminating the need for manual force to complete the docking.

[0075] In order to accurately apply the pneumatic force, the docking cylinder 32 includes a cylinder barrel 321 and a piston rod 322. An eccentric connecting arm 34 is provided at one end of the piston rod 322 exposed from the cylinder barrel 321. The detection plug part 31 is connected to the eccentric end of the eccentric connecting arm 34, wherein the eccentric end is the side of the eccentric connecting arm 34 away from the piston rod 322. The detection plug part 31 includes a docking terminal 311 and a detection device 312. A buffer spring 313 is provided at the connection between the docking terminal 311 and the detection device 312. The buffer spring 313 can buffer the pneumatic force provided by the docking cylinder 32, and can also enable the docking terminal 311 to have a certain degree of mobility, that is, it can swing within a certain range, so that the direction of the docking terminal 311 is offset relative to the vertical direction, so that the docking terminal 311 can meet the needs of vertical terminals and inclined terminals. Furthermore, the angle adjustment mechanism 33 is arranged on one side of the cylinder 321. At the same time, the angle adjustment mechanism 33 is located in the angle adjustment side groove 541 of the adjustment connecting column 54 arranged between the position adjustment mechanism 5 and the probe assembly 3. The angle adjustment side groove 541 is located at one end of the adjustment connecting column 54 close to the probe assembly 3. The angle adjustment mechanism 33 includes but is not limited to the angle adjustment plate 331 and the butterfly bolt 332. The butterfly bolt 332 sequentially penetrates the screw hole of the side groove bottom 5411 of the angle adjustment side groove 541, the screw hole of the angle adjustment plate 331 and the screw hole of the side wall 3211 of the cylinder 321. It can be understood that the side groove of the angle adjustment side groove 541 A first screw hole is provided on the bottom 5411, a second screw hole is provided on the angle adjustment plate 331, and a third screw hole is provided on the side wall 3211 of the cylinder 321. When the angle adjustment mechanism 33 is in the angle adjustment side groove 541, the first screw hole, the second screw hole and the third screw hole are in the same straight line, forming a channel for the screw rod of the butterfly bolt 332 to pass through. The inner walls of the screw holes of the first screw hole, the second screw hole and the third screw hole can be provided with threads matching the threads of the screw rod of the butterfly bolt 332, so that the butterfly bolt 332 can cooperate with the first screw hole, the second screw hole and the third screw hole to fix the angle adjustment plate 331 and the cylinder 321 to the angle adjustment side groove 541.

[0076] When the butterfly bolt 332 is in a loose state, that is, when the butterfly bolt 332 is loosened, the angle adjustment plate 331 is in an active state and can rotate with the screw of the butterfly bolt 332 as the axis core, thereby driving the cylinder 321 to rotate with the screw of the butterfly bolt 332 as the axis core. When it is rotated to a preset angle, the butterfly bolt 332 is tightened again to fix the angle adjustment plate 331 and the cylinder 321.

[0077] Therefore, with the joint cooperation of the buffer spring 313 and the angle adjustment mechanism 33, the probe assembly 3 can be rotated and tilted to meet the needs of various terminal settings, which is conducive to flexibly and stably completing the detection of compressor inter-turn short circuits, ensuring that the pneumatic force of the docking cylinder 32 can be accurately applied, and avoiding damage to the probe assembly 3 and the terminal.

[0078] From the above-mentioned embodiment 2, the following beneficial effects can be seen:

[0079] By arranging a detection plug part, a docking cylinder and an angle adjustment mechanism in the probe assembly, the buffer spring in the detection plug part can buffer the pneumatic force provided by the docking cylinder and also enable the docking terminal to have a certain degree of mobility. The angle adjustment mechanism can adjust the inclination angle of the probe assembly so that the probe assembly can be rotatable and tilted to meet the needs of various terminal posts. This is conducive to flexibly and stably completing the detection of compressor inter-turn short circuits, improving the flexibility of the probe assembly when connecting the terminal post, ensuring that the pneumatic force of the docking cylinder can be accurately applied, reducing the repeated plugging and unplugging of the probe, and avoiding damage to the probe assembly and the terminal post during the connection process.

[0080] Embodiment 3

[0081] For ease of understanding, an embodiment of an automatic detection device for compressor inter-turn short circuit is provided below for illustration. In actual applications, the terminals of compressors of different models will be in different positions, so the position of the probe assembly needs to be adjusted to meet various detection requirements.

[0082] See also Figure 1 , Figure 4 and Figure 5 The third embodiment of the automatic detection device for short circuit between turns of a compressor shown in the embodiment of the present application includes:

[0083] The position adjustment mechanism 5 includes a length adjustment mechanism 51, a width adjustment mechanism 52 and a servo lifting mechanism 53. In the embodiment of the present application, a spatial rectangular coordinate system can be established within the active range of the probe assembly. The Z axis of the spatial rectangular coordinate system is parallel to the lifting motion trajectory of the servo lifting mechanism 53. It can be understood that the length adjustment mechanism 51 adjusts the position of the probe assembly in the X-axis direction in the spatial rectangular coordinate system, while the width adjustment mechanism 52 adjusts the position of the probe assembly in the Y-axis direction in the spatial rectangular coordinate system.

[0084] In the embodiment of the present application, the servo lifting mechanism 53 includes a lifting connection plate 531 and a lifting mechanism body 532. The lifting mechanism body 532 provides the lifting connection plate 531 with power for lifting and lowering movement. Therefore, one end of the lifting connection plate 531 is connected to the lifting mechanism body 532, so that the lifting mechanism body 532 can drive the lifting connection plate 531 to move in the vertical direction. The other end of the lifting connection plate 531 is connected to the width adjustment mechanism 52, and the length adjustment mechanism 51 is connected to the adjustment connection column 54. The width adjustment mechanism 52 is arranged between the length adjustment mechanism 51 and the other end of the lifting connection plate 531, so that when the lifting connection plate 531 moves in the vertical direction, it can drive the length adjustment mechanism 51 and the width adjustment mechanism 52 to move in the vertical direction. Since the probe assembly 3 is connected to the adjustment connection column 54, the position of the probe assembly 3 can be adjusted by the length adjustment mechanism 51, the width adjustment mechanism 52 and the servo lifting mechanism 53.

[0085] It can be understood that, in actual applications, the connection sequence of the length adjustment mechanism 51 and the width adjustment mechanism 52 can be adjusted, that is, the length adjustment mechanism 51 can also be arranged between the width adjustment mechanism 52 and the other end of the lifting connection plate 531. At this time, the width adjustment mechanism 52 is connected to the adjustment connection column 54, and the other end of the lifting connection plate 531 is connected to the length adjustment mechanism 51. The length adjustment mechanism 51 and the width adjustment mechanism 52 can be separated by a connecting plate tooling. The connection sequence needs to be determined according to the actual application situation, and is not limited here.

[0086] In the embodiment of the present application, the adjustment rails on the length direction adjustment mechanism 51 and the width direction adjustment mechanism 52 can be respectively driven to adjust their positions by turning the handles on the length direction adjustment mechanism 51 and the width direction adjustment mechanism 52. The turning method can be automatic control turning through mechanical equipment or manual turning, which is not limited here.

[0087] From the above embodiment 3, the following beneficial effects can be seen:

[0088] The position of the probe assembly is adjusted by the position adjustment mechanism, so that the probe assembly can efficiently dock with the terminal posts at different positions in compressors of different models to meet various detection requirements.

[0089] Embodiment 4

[0090] For ease of understanding, an embodiment of the automatic detection device for short-circuit between turns of a compressor is provided below for illustration. In actual applications, the positioning tooling plate is smaller than the transport assembly line, and there is inevitably a gap between the front and rear positioning tooling plates on the transport assembly line, resulting in deviations in the positions of each compressor. The positioning claw assembly is required to achieve consistent positioning of each compressor. In addition, a liquid distributor is provided on the compressor, but the liquid distributors of compressors of different models are set in different positions. After the compressor is positioned on the positioning tooling plate, some compressor distributors are located in front of the compressor, and some are located behind the compressor. Therefore, the positioning claw assembly is provided with a pair of liquid distributor claws, which are located on both sides of the compressor housing claws to achieve better positioning of the compressor.

[0091] See also Figure 1 , Figure 6 and Figure 7 The fourth embodiment of the automatic detection device for short circuit between turns of a compressor shown in the embodiment of the present application includes:

[0092] The first claw assembly 21 includes a first liquid dispenser claw 211, a second liquid dispenser claw 212 and a compressor housing plane claw 213, the second claw assembly 22 includes a third liquid dispenser claw 221, a fourth liquid dispenser claw 222 and a compressor housing V-shaped claw 223, the first liquid dispenser claw 211 and the third liquid dispenser claw 221 are symmetrically arranged, the second liquid dispenser claw 212 and the fourth liquid dispenser claw 222 are symmetrically arranged, the compressor housing plane claw 213 and the compressor housing V-shaped claw 223 are symmetrically arranged, it can be understood that Yes, taking the compressor housing plane claw 213 and the compressor housing V-shaped claw 223 as examples, the symmetrical arrangement means that the compressor housing plane claw 213 and the compressor housing V-shaped claw 223 are symmetrical with the perpendicular bisector of the line connecting the two as the symmetry axis, but the claw shapes of the two claws can be consistent or inconsistent, that is, for example, the claw shapes of the first liquid dispenser claw 211 and the third liquid dispenser claw 221 can be consistent, and the claw shapes of the compressor housing plane claw 213 and the compressor housing V-shaped claw 223 are inconsistent.

[0093] In the embodiment of the present application, when the photoelectric sensor 4 detects that the positioning tooling plate 1 runs to the detection position, the first propulsion cylinder group 214 of the first claw assembly 21 drives the first claw assembly 21 to first reach the preset position to limit the position of the compressor. Therefore, the claw forms of the first liquid dispenser claw 211, the second liquid dispenser claw 212 and the compressor housing plane claw 213 are all plane claws, and the first propulsion cylinder group 214 is in a self-locking state to fix the positions of the first liquid dispenser claw 211, the second liquid dispenser claw 212 and the compressor housing plane claw 213. At the same time, the second propulsion cylinder group 224 of the second claw assembly 22 is still in the propulsion state, driving the third liquid distributor claw 221, the fourth liquid distributor claw 222 and the compressor housing V-shaped claw 223. At this time, the claw used to propel the compressor is a V-shaped claw, which can play a certain surrounding role on the compressor 7 to prevent the compressor 7 from shifting on the propulsion track. The third liquid distributor claw 221 and the fourth liquid distributor claw 222 are used to push the liquid distributor and assist the propulsion of the compressor 7. Therefore, their claw shapes are all flat claws. The second propulsion cylinder group 224 of the second claw assembly 22 pushes the compressor 7 until the compressor 7 abuts against the first claw assembly 21, and the second claw assembly 22 changes from the propulsion state to the self-locking state. The compressor 7 is clamped between the first claw assembly 21 and the second claw assembly 22, completing the positioning of the compressor 7.

[0094] From the above-mentioned fourth embodiment, the following beneficial effects can be seen:

[0095] The compressor is clamped and fixed by the first clamping claw assembly and the second clamping claw assembly to complete the positioning of the compressor, so that the positioning of each compressor is consistent. When the same model of compressors is tested, the positions of the terminals are guaranteed to be the same, thereby effectively improving the testing efficiency. When different models of compressors are tested, the position adjustment mechanism can be quickly adjusted according to the compressor model control, and the probe assembly can be quickly adjusted to the terminal corresponding to the compressor model, without the need to recalibrate the position of the probe assembly, thereby improving the testing efficiency.

[0096] Embodiment 5

[0097] For ease of understanding, an embodiment of an automatic detection device for short circuit between turns of a compressor is provided below for illustration. In actual applications, the locating pin also includes a second locating pin so as to cooperate and position the L-shaped bracket of the compressor. In addition, the locating tooling plate will also have a locating hole to correct the angular deviation of the locating tooling plate on the transport assembly line to ensure the accuracy of subsequent clamping and fixing by the locating claw assembly.

[0098] See also Figure 2 , Fig. 9 and Fig.10The fifth embodiment of the automatic detection device for short circuit between turns of a compressor shown in the embodiment of the present application includes:

[0099] The positioning pin also includes a second positioning pin 12, which is used to cooperate with the L-shaped bracket of the compressor for positioning. It can be understood that if Fig. 9 As shown, the second positioning pin 12 can be inserted into the limiting hole in the rectangular bracket foot of the compressor L-shaped bracket to complete the positioning, or it can be abutted and limited with the edge position of the rectangular bracket foot of the compressor L-shaped bracket to achieve positioning. In actual applications, the L-shaped bracket of the compressor can also be positioned in other ways, which depends on the actual application situation and is not the only limitation here.

[0100] In the embodiment of the present application, there are M first locating pins 11 and N second locating pins 12, M and N are positive integers, M and N can be the same value or different values, preferably, M and N are both 3, but it is not limited to this. The first locating pins 11 and the second locating pins 12 are arranged alternately, the rotation angles between adjacent first locating pins 11 are consistent, and the rotation angles between adjacent second locating pins 12 are consistent, and the rotation angles are determined according to the number of the first locating pins 11 and the second locating pins 12.

[0101] M first positioning pins 11 are located on the first circumference, and N second positioning pins 12 are located on the second circumference. The radius of the first circumference is greater than the radius of the second circumference. This is because the radii of the triangular bracket and the L-shaped bracket are inconsistent, and the radius of the triangular bracket is greater than the radius of the L-shaped bracket.

[0102] Furthermore, P positioning holes 13 are provided on the positioning tooling plate 1, where P is a positive integer. Preferably, the value of P is 4, so that the positioning holes 13 can be distributed at the four vertex corners of the positioning tooling plate 1. When the positioning tooling plate 1 is transported to the inspection station through the assembly line, the jacking mechanism of the inspection station passes through the P positioning holes 13 and detaches the positioning tooling plate 1 from the assembly line, so as to correct the angular deviation of the positioning tooling plate on the transportation assembly line through the jacking mechanism, and then perform the step of clamping and fixing it through the positioning claw assembly.

[0103] Therefore, the positioning steps before the compressor performs inter-turn short-circuit detection can be set as follows: positioning the compressor bracket with the positioning pins on the positioning tooling plate, and then transporting the positioning tooling plate to the inspection station through the transport line, and correcting the angular deviation of the positioning tooling plate on the transport line through the jacking mechanism in the inspection station and the positioning holes in the positioning tooling plate, and then driving the positioning claw assembly to clamp and fix the compressor to ensure the positioning accuracy of the compressor.

[0104] From the above embodiment 5, the following beneficial effects can be seen:

[0105] By setting the first positioning pin and the second positioning pin, the positioning tooling plate can position the triangular bracket and the L-shaped bracket of the compressor, thereby expanding the scope of application. By setting the positioning hole on the positioning tooling plate, the angular deviation of the positioning tooling plate on the transport assembly line can be corrected in cooperation with the jacking mechanism to ensure the accuracy of subsequent clamping and fixing by the positioning claw assembly, thereby improving the detection efficiency.
