The current compressor production process is: the rotor, stator and pump body are installed into the compressor housing - the upper cover terminal and screw welding - the upper and lower covers are installed with the housing - the compressor performance test.

[0003] However, the terminal test is carried out after the upper cover of the compressor is welded. To detect abnormalities, it is necessary to cut and weld the upper and lower covers, disassemble the internal parts, and check the abnormal position. If there is a problem at a certain node in the compressor production process, resulting in abnormal performance detection of the compressor, the batch of compressors that have undergone performance testing of the whole machine can only be scrapped.

[0043] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0044] In order to solve the technical problems in the prior art, the present invention is further described in conjunction with the accompanying drawings and embodiments:

[0045] like Figures 1 to 3 As shown, an embodiment of the present invention discloses an automatic testing device for a compressor 8, comprising an angle adjustment mechanism 1, a sensor 2, a rotating assembly 3 and a docking mechanism 4, the docking mechanism 4 is mounted with the sensor 2 and the electric plug 41, the rotating assembly 3 is connected to the angle adjustment mechanism 1, the angle adjustment mechanism 1 is equipped with the docking mechanism 4, the angle adjustment mechanism 1 drives the docking mechanism 4 to rotate around a first axis and around a second axis, the first axis and the second axis are respectively perpendicular to the rotation axis of the rotating assembly 3, and the rotation axis of the rotating assembly 3 is consistent with the central axis of the housing of the compressor 8 to be tested.

[0046] When the rotating assembly 3 drives the angle adjustment mechanism 1 and the docking mechanism 4 to rotate, when the sensor 2 rotates and detects the positioning point of the compressor 8 to be tested, the electric plug 41 of the docking mechanism 4 is opposite to the terminal 82 of the compressor 8 to be tested, and the terminal 82 can be docked with the electric plug 41, thereby realizing automatic docking test of the compressor terminal 82.

[0047] The automatic testing device for compressor 8 of the present embodiment can be applied to the testing of the terminal 82 of the upper cover 81 during the assembly process of the compressor 8. Since the upper cover 81 of the compressor 8 is not welded to the compressor shell during the assembly process, the center of the upper cover 81 of the compressor 8 is offset relative to the center of the shell during assembly. The upper cover 81 is usually placed on the upper end of the shell of the compressor 8 to be tested and transported to the inspection station via a conveyor line. It should be noted that the offset does not result in a large misalignment, and the sensor 2 can be used to achieve search and positioning based on the principle of center offset.

[0048] Therefore, in this embodiment, the rotation axis of the rotating component 3 is adjusted to be consistent with the central axis of the shell of the compressor 8 to be tested, and the sensor 2 on the docking mechanism 4 is driven by the rotating component 3 to rotate and locate the positioning point of the compressor 8 to be tested. The exemplary positioning point is the screw 83 of the upper cover 81 of the compressor 8. When the sensor 2 detects the screw 83, the sensor 2 outputs a signal to the controller, and the controller sends a start signal to dock the electric plug 41 of the docking mechanism 4 with the terminal 82 of the upper cover 81 of the compressor 8 to be tested to realize automatic testing.

[0049] It is important to understand that, for example, Figure 5 As shown, the screw 83 is used as the positioning point position that the sensor 2 looks for during the test. When the sensor 2 detects the screw 83, the electric plug 41 on the docking mechanism 4 can cooperate with the terminal 82 of the upper cover 81 of the compressor 8 to be tested. In this way, the rotating component 3 and the sensor 2 are used to assist in locating the terminal 82 position, solving the problem that the accuracy of the automatic test docking terminal 82 is difficult to ensure when the upper and lower covers of the compressor 8 to be tested are not welded during the assembly process. Of course, other positions of the upper cover 81 can also be designed as positioning points. It is only necessary to ensure that when the sensor 2 detects the positioning point, the electric plug 41 and the terminal 82 of the upper cover 81 of the compressor 8 can be effectively docked to complete the test.

[0050] Next, in this embodiment, the terminal 82 of the upper cover 81 of the compressor 8 is in a flat and inclined state (such as Figure 5As shown), in order to further improve the accuracy of the automatic docking of the electric plug 41, an angle adjustment mechanism 1 is added to be connected to the docking mechanism 4, and the angle adjustment mechanism 1 drives the docking mechanism 4 to rotate around the first axis and the second axis respectively, and the first axis and the second axis are respectively perpendicular to the rotation axis of the rotating component 3, so that the electric plug 41 on the docking mechanism 4 can achieve a certain amplitude of swing, satisfying the terminal 82 in the vertical state and the inclined state, and the angle adjustment mechanism 1 can be compatible with more models of compressors 8.

[0051] It should be noted that the angle adjustment mechanism 1 drives the docking mechanism 4 to adjust the tilt angle. The first axis and the second axis may be perpendicular to each other or not. That is, the angle between the first axis and the second axis may be an acute angle or an obtuse angle to be compatible with the testing of more complex compressor 8 terminals 82.

[0052] Preferably, in this embodiment, the first axis and the second axis are set perpendicular to each other. The angle adjustment mechanism 1 and the docking mechanism 4 can achieve angle adjustment in two directions, with a wider adjustment range, and can also be compatible with more complex compressor 8 terminal 82 tests.

[0053] Also, if Figure 5 As shown, since the upper cover 81 is not welded to the compressor 8 housing, when the test result is abnormal, there is no need to cut and weld the upper cover 81 of the compressor 8. The operator can directly open the upper cover 81 to detect abnormal parts, which is convenient for timely tracing back to the process with problems, and then directly improving the problematic process. In this way, the problem of the risk of scrapping a batch of compressors 8 due to a problem in a process caused by welding the upper cover 81 to the compressor 8 housing in the traditional test method is effectively avoided.

[0054] Of course, the test device of this embodiment does not exclude the use of the terminal 82 test of the compressor 8 that has been assembled. The sensor 2 and the rotating assembly 3 can quickly find the positioning point of the compressor 8 to be tested, and efficiently complete the matching and docking of the electric plug 41 and the terminal 82 of the upper cover 81, ensuring the accurate docking of the automated test, and the angle adjustment mechanism 1 can be compatible with the terminal 82 test of more models of compressors 8.

[0055] This test device replaces manual testing, and judgment is made through detection equipment. Human subjective judgment may lead to misjudgment and missed judgment.

[0056] In some embodiments, Figure 2 and Figure 3 As shown, the angle adjustment mechanism 1 includes a front and rear tilting assembly and a left and right tilting assembly, the docking mechanism 4 is installed on the left and right tilting assembly, the left and right tilting assembly is connected to the front and rear tilting assembly, the front and rear tilting assembly is connected to the rotating assembly 3, and the rotating assembly 3 can drive the front and rear tilting assembly, the left and right tilting assembly and the docking mechanism 4 to rotate as a whole.

[0057] Furthermore, the sensor 2 uses a laser sensor. The left and right tilting driving member 13 is connected to the connecting plate 42 through the left and right tilting block 14. The laser sensor is installed on the side of the connecting plate 42 of the electric plug 41, and the electric plug 41 is installed below the connecting plate 42. The laser sensor is used for positioning.

[0058] Furthermore, the rotating assembly 3 is provided with a rotating motor 32 to provide a driving force for driving the angle adjustment mechanism 1 , the docking mechanism 4 and the sensor 2 to rotate, and the rotating motor 32 is vertically arranged.

[0059] In actual applications, the upper cover 81 of the compressor 8 is not welded during the assembly process. During assembly, the upper cover 81 of the compressor 8 is offset relative to the center of the shell. Before testing, the center of rotation of the rotating motor 32 is adjusted to be consistent with the center of the compressor 8 shell. Laser positioning is applied based on the principle of center offset. The laser sensor emits a laser point. Using the laser emission principle, the rotating group motor drives the laser sensor to rotate, and the relative position above the screw 83 is higher. After rotating to the position above the screw 83, the positioning stops. The electric plug 41 is used to dock with the compressor 8 terminal 82 after positioning, and the relative position of the compressor 8 screw 83 and the terminal 82 is fixed.

[0060] In an alternative embodiment, the sensor 2 may be a color mark sensor, and a color mark sensor is provided at the location of the compressor 8 to detect and identify the color mark. In this way, when the rotating motor 32 drives the color mark sensor to rotate, the color mark sensor detects the location point, and the electric plug 41 of the docking mechanism 4 is opposite to the terminal 82 of the upper cover 81 of the compressor 8, and the docking test can be automatically performed.

[0061] The sensor 2 may also be other sensors or devices, and it is only necessary to ensure that when the sensor 2 detects the positioning point on the compressor 8, the electric plug 41 and the terminal 82 are accurately connected.

[0062] Usually, during the production and assembly process of the compressor 8, the system will record the information of the compressor 8, including the compressor 8 model, the inclination information of the terminal 82, etc. Before testing the terminal 82 of the compressor 8, the operator pre-adjusts the angle adjustment mechanism 1 according to the information of the compressor 8, specifically adjusts the rotation degree of the front and rear inclination components and the left and right inclination components, so as to adjust the inclination angle of the electric plug 41 on the docking mechanism 4, so that after the sensor 2 detects the positioning point of the compressor 8, the electric plug 41 and the terminal 82 are exactly arranged opposite to each other, and the positioning point is preferably located at the upper cover 81.

[0063] If the positioning point detected by the sensor 2 changes, before the connection test between the terminal 82 and the electric plug 41, the operator also adjusts the installation position of the sensor 2 according to the positioning point position in advance to ensure that the electric plug 41 is opposite to the terminal 82 when the sensor 2 detects the positioning point.

[0064] Since the upper cover 81 is not welded and fixed, the compressor 8 is placed in an unused position on the conveyor line, etc., after pre-adjusting the tilt angle of the electric plug 41, the sensor 2 and the rotating assembly 3 are used to quickly find the positioning point, and the electric plug 41 and the terminal 82 are quickly connected, thereby improving the reliability and accuracy of the automated test connection.

[0065] When the terminal 82 in the vertical state is automatically tested, the front and rear tilting components and the left and right tilting components are in the initial positions, and the tilt angle of the electric plug 41 does not need to be adjusted. At this time, the electric plug 41 is in the vertical state. After the sensor 2 detects the positioning point pre-set on the upper cover 81, such as the screw 83, the electric plug 41 is just above the terminal 82. By controlling the displacement adjustment mechanism 7 to control the angle adjustment mechanism 1, the rotating component 3 and the docking mechanism 4 to move downward as a whole, the electric plug 41 is effectively in contact with the terminal 82, and the test item of the terminal 82 of the compressor 8 is completed.

[0066] Furthermore, if Figure 3 As shown, the front-to-back tilt assembly includes a front-to-back tilt driving member 11 and a front-to-back tilt block 12, and the left-to-right tilt assembly includes a left-to-right tilt driving member 13 and a left-to-right tilt block 14. The front-to-back tilt driving member 11 is connected to the rotating assembly 3 through the front-to-back tilt block 12, and the left-to-right tilt driving member 13 is connected to the front-to-back tilt driving member 11 through the left-to-right tilt block 14. Through the front-to-back tilt block 12 and the left-to-right tilt block 14, the front-to-back tilt motor and the left-to-right tilt motor are integrally connected to the rotating assembly 3, and the rotating assembly 3 drives the front-to-back tilt assembly and the left-to-right tilt assembly to rotate together.

[0067] Furthermore, the output end of the front and rear tilting driving member 11 is connected to a first swing head 15, which is fixedly connected to the left and right tilting blocks 14; the output end of the left and right tilting driving member 13 is connected to a second swing head 16, which is fixedly connected to the docking mechanism 4.

[0068] The first swing head 15 is driven to rotate around the rotation axis of the front and rear tilt driving member 11, i.e., the first axis, through the front and rear tilt driving member 11, so that the left and right tilting components and the docking mechanism 4 rotate around the first axis as a whole, so that the angle between the central axis of the electric plug 41 and the rotation axis of the rotating component 3 or the central axis of the compressor 8 housing is adjusted within a certain range.

[0069] And by driving the second swing head 16 to rotate around the rotation axis of the left and right tilting driving member 13, that is, the second axis, through the left and right tilting driving member 13, the docking mechanism 4 rotates around the second axis, and the angle between the central axis of the electric plug 41 and the rotation axis of the rotating assembly 3 or the central axis of the compressor 8 housing is also adjusted within a certain range.

[0070] like Figure 2 and Figure 3 As shown, the design of the front and rear tilting driving member 11 and the left and right tilting driving member 13 increases the tilting angle adjustment range of the electric plug 41, and is suitable for docking tests of the terminal 82 of different types of compressors 8. In this embodiment, the rotation axis / first axis of the front and rear tilting driving member 11 and the rotation axis / second axis of the left and right tilting driving member 13 are perpendicular to each other, so that the tilting angle of the electric plug 41 in the X and Y directions can be adjusted.

[0071] Furthermore, a first mounting groove 121 for accommodating the rotation of the first swing head 15 is provided on the front and rear tilting blocks 12 , and a second mounting groove 141 for accommodating the rotation of the second swing head 16 is provided on the left and right tilting blocks 14 .

[0072] Furthermore, the front-rear tilting driving member 11 and the left-right tilting driving member 13 adopt swing motors.

[0073] In actual application, the swing angles of the front-to-back tilting driving member 11 and the left-to-right tilting driving member 13 are both 180°. The front-to-back tilting driving member 11 drives the electric plug 41 to swing by a certain amplitude through the first swing head 15, and the left-to-right tilting driving member 13 drives the electric plug 41 through the second swing head 16, so that the tilt angle of the electric plug 41 is consistent with the tilt angle of the terminal 82 of the upper cover 81 of the compressor 8, thereby improving the accuracy of the automated test docking.

[0074] In some embodiments, the test device further includes a claw mechanism, which is used to position the compressor 8. The claw mechanism has a first claw assembly 5, which is provided with a first positioning block 51 and a positioning buckle 52, the first positioning block 51 is provided with a first contoured groove 511 matching the shell profile of the compressor 8, the positioning buckle 52 is fixedly connected to the first positioning block 51, and the positioning buckle 52 has a contoured block for clamping the dispenser bracket 84.

[0075] The first claw assembly 5 is arranged close to one side of the dispenser bracket 84 of the compressor 8. The dispenser bracket 84 of the compressor 8 is positioned by the first claw assembly 5, thereby positioning one side of the compressor 8 shell and realizing limited positioning of the compressor 8 during automated testing. The other side of the compressor 8 can be positioned using the existing structure, so that when the terminal 82 is docked with the electric plug 41 for testing, the position of the compressor 8 is fixed.

[0076] In a specific example, the claw mechanism also includes a second claw assembly 6. The first claw assembly 5 is arranged opposite to the second claw assembly 6. The second claw assembly 6 is provided with a second positioning block 61. The second positioning block 61 is provided with a second contoured groove matching the shell contour of the compressor 8.

[0077] The compressor 8 is positioned by the relatively arranged first claw assembly 5 and second claw assembly 6 to avoid shaking and instability of the compressor 8 during the automatic testing process, which would affect the docking accuracy of the terminal 82 and the electric plug 41.

[0078] For example, the first claw mechanism includes a positioning buckle 52, a first positioning block 51, a cylinder and a fixing device for positioning, and the second claw mechanism has no buckle relative to the first claw mechanism and has a second positioning block for fixing. Figure 4 As shown, both the first positioning block 51 and the second positioning block 61 are provided with V-shaped profiling grooves for matching and clamping the compressor 8 housing.

[0079] The claw action is that after the compressor 8 is detected to be in place, the second claw assembly 6 moves first to reach the rear of the compressor 8, and the first claw assembly 5 moves later. When approaching the compressor 8, the positioning buckle 52 contacts and positions the liquid distributor bracket 84 of the compressor 8, and then pushes the compressor 8 to the second positioning block 61 of the second claw assembly 6 to be fixed, completing the claw action. For different models of compressors 8, the structure of the liquid distributor bracket 84 is different, and the positioning buckle 52 will also be replaced.

[0080] For example, Figure 5 and Figure 6 The compressor 8 is shown in the figure, and the product is in the production and assembly process. The compressor 8 includes a liquid distributor bracket 84, a screw 83 and a terminal 82. The liquid distributor bracket 84 is connected to the positioning buckle 52 for positioning and fixing the compressor 8. The screw 83 is used for the laser sensor to locate the position. The terminal 82 is connected to the electric plug 41 for power-on startup test.

[0081] Figure 8 The figure is a schematic diagram of an electric plug 41 for docking with the terminal 82 of the compressor 8. Since the lower part of the terminal 82 is an insulating glass body, excessive docking force may easily cause damage to the glass body. The electric plug 41 has a multi-section elastic probe 411 inside. The elastic probe 411 can achieve a certain range of expansion and contraction along the central axis of the terminal 82 to ensure effective docking between the elastic probe 411 and the terminal 82, and better protect the terminal 82 of the compressor 8 during docking.

[0082] This embodiment also includes a displacement adjustment mechanism 7, which is provided with a front-rear adjustment unit 76, a left-right adjustment unit 74 and an up-down adjustment unit 71. The up-down adjustment unit 71 is connected to one side of the left-right adjustment unit 74, and the other side of the left-right adjustment unit 74 is connected to the front-rear adjustment unit 76. The front-rear adjustment unit 76 is connected to the rotating component 3.

[0083] The angle adjustment mechanism 1, the docking mechanism 4, the rotating assembly 3 and the displacement adjustment mechanism 7 are assembled on a frame 9, and the frame 9 is vertically installed on the ground to ensure the stability of the device.

[0084] Among them, the docking mechanism 4 is used to dock with the terminal 82 of the compressor 8, and the up and down adjustment unit 71 is fixed on the top of the frame 9 through the upper and lower mounting plates 72. The up and down adjustment unit 71 includes a linear motor and an adjustment guide rail (consistent with other adjustment units) to provide power for adjusting the docking mechanism 4 to move up and down and dock with the terminal 82 of the upper cover 81 of the compressor 8.

[0085] The up-down adjustment unit 71 is connected to the left-right adjustment unit 74 through the up-down connection block 73, and the left-right adjustment unit 74 is used to adjust the left-right movement of the docking mechanism 4. The left-right adjustment unit 74 is connected to the front-back adjustment unit 76 through the left-right connection block 75, and the front-back adjustment unit 76 is used to adjust the front-back movement of the docking mechanism 4.

[0086] In actual application, the front and rear adjustment unit 76 is connected to the rotary motor 32 of the rotating assembly 3 through the front and rear connecting blocks 77, and the rotary motor 32 is used to drive the laser sensor to rotate and locate the screw 83 on the compressor 8. The rotary motor 32 is connected to the front and rear tilting drive member 11 through the rotating mounting plate 31, and the front and rear tilting drive member 11 is connected to the left and right tilting drive member 13 through the front and rear tilting blocks 12. Since the terminal 82 of the compressor 8 has a plane and an inclined state, the front and rear tilting drive member 11 and the left and right tilting drive member 13 make the tilt angle of the electric plug 41 more adjustable, and more compressors 8 can be compatible.

[0087] A touch screen button box 91 is installed on the rack 9. The touch screen button box 91 is installed in the middle position on the right side of the rack 9 and is used to install the device touch screen and buttons, so that employees can control the overall operation of the device through the touch screen and buttons.

[0088] The automatic test process of the compressor 8 terminal 82 specifically includes the following steps:

[0089] Before starting debugging, the operator adjusts the front and rear adjustment unit 76, the left and right adjustment unit 74, the front and rear tilt motor and the left and right tilt motor according to the positions of the terminal 82 of different compressor models 8. The above mechanisms do not work during the test process.

[0090] Figure 5 After the compressor 8 shown is in place, Figure 4 The first claw assembly 5 shown in the figure moves, so that the first positioning block 51 and the positioning buckle 52 are perfectly docked and positioned with the liquid distributor bracket 84 on the compressor 8. Figure 7 As shown, after the first claw assembly 5 positions one side of the compressor 8, the compressor 8 is pushed toward the second claw assembly 6 which is arranged oppositely, and the first positioning block 51 and the positioning buckle 52 of the first claw assembly 5 and the second positioning block 61 of the second claw assembly 6 jointly fix the compressor 8.

[0091] After the compressor 8 is positioned, the rotating motor 32 of the rotating assembly 3 is actuated to drive the laser sensor to locate the position. After finding the screw 83 of the compressor 8, the up-down adjustment unit 71 is actuated to move the docking mechanism 4 downward, and the electric plug 41 is in perfect contact with the terminal 82 of the compressor 8. The equipment is powered on to start testing, and the touch screen in the touch screen button box 91 displays the current test status. When an abnormality is detected, the equipment alarms and waits for manual processing. When the detection display is normal, the test is completed, the up-down adjustment unit 71 is actuated to move the docking mechanism 4 upward and return to the initial point. The claw mechanism is actuated to release the compressor 8. The action is completed, the compressor 8 flows out, and the automatic detection function is completed.

[0092] Using this automatic testing device, the action flow of this process is: debug the position of the docking mechanism 4 - positioning, finding the position and docking - power on to start testing - after the test is qualified, the device mechanism returns to the origin - the compressor 8 flows away. Compared with the original manual test, it solves the problem of difficult docking and positioning in the assembly process in the industry, and has the advantages of accurate positioning and high compatibility and adaptability.

[0093] The main functions of the present invention are:

[0094] 1. Applied to the automatic docking test of terminal posts during compressor assembly process, using sensors and rotating components to locate positioning points to ensure perfect docking between the electric plug and the terminal posts, thereby improving the accuracy of automatic docking.

[0095] 2. During the test, the first positioning block and positioning buckle of the first claw assembly are used to position the dispenser bracket, and the second claw assembly is used to achieve effective limiting during the automatic test of the compressor.

[0096] 3. Add an angle adjustment mechanism, use the front and rear tilt drive parts and the left and right tilt drive parts to effectively adjust the tilt angle of the electric plug, which can adapt to the automatic docking test of the terminal in the vertical state and the tilted state, and cooperate with the displacement adjustment mechanism to achieve a larger adjustment range and be compatible with more complex compressor model terminal tests.

[0097] 4. The test device is used to automate the terminal docking test, which can reliably and automatically locate the docking and position adjustment, solving the problem of misjudgment and missed judgment caused by subjective manual judgment in the original test mode of the industry.

[0098] In summary, after reading the present invention document, ordinary technicians in this field can make various other corresponding transformation schemes based on the technical scheme and technical concept of the present invention without creative mental work, which all fall within the scope of protection of the present invention.
