Description

Technical Field

[0001] This utility model relates to the technical field of compressor testing equipment, and in particular to an automatic compressor testing device. Background Technology

[0002] During the production and processing of air conditioner compressors, relevant testing positions must be set up to prevent batch accidents caused by abnormalities in the upstream production process. The current compressor production process is as follows: rotor, stator and pump body are installed into the compressor housing - top cover terminals and screws are welded - upper and lower covers are installed with the housing - compressor performance testing.

[0003] However, after the compressor's top cover is welded, terminal testing is performed. If an anomaly is detected, the top and bottom covers need to be cut and welded, and internal parts need to be disassembled to check for the problem. If a problem occurs at any stage of the compressor manufacturing process, causing abnormal compressor performance testing, the entire batch of compressors undergoing performance testing must be scrapped. Currently, compressor performance testing in the industry is conducted after the compressor is fully assembled; there is no information available on performing compressor performance testing directly during assembly. In practice, without the installation of the housing support frame and the welding of the top and bottom covers and distributor, there are difficulties in compressor positioning and ensuring the accuracy of automatic testing and docking terminal connections.

[0043] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

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

[0045] like Figures 1 to 3As shown in the figure, this utility model embodiment discloses an automatic testing device for a compressor 8, including an angle adjustment mechanism 1, a sensor 2, a rotating assembly 3, and a docking mechanism 4. The docking mechanism 4 is equipped with a sensor 2 and an electrical plug 41. The rotating assembly 3 is connected to the angle adjustment mechanism 1, and 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 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 component 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 under test, the electrical plug 41 of the docking mechanism 4 is aligned with the terminal 82 of the compressor 8 under test, which can realize the docking of the terminal 82 and the electrical plug 41, and realize the automatic docking test of the compressor terminal 82.

[0047] The automatic testing device for compressor 8 in this embodiment can be applied to test the terminals 82 of the upper cover 81 during the assembly process of compressor 8. Since the upper cover 81 of compressor 8 is not welded to the housing of compressor 8 during the assembly process, the center of the upper cover 81 of compressor 8 is offset relative to the center of the housing during assembly. Usually, the upper cover 81 is placed on the upper end of the housing of compressor 8 to be tested and transported to the testing station by the conveyor line. It should be noted that this offset will not be a large misalignment. The sensor 2 can be used to locate the position based on the principle of the center offset.

[0048] Therefore, in this embodiment, the rotation axis of the rotating component 3 is aligned with the central axis of the housing of the compressor 8 under test. The rotating component 3 drives the sensor 2 on the docking mechanism 4 to rotate and locate the positioning point of the compressor 8 under test. In this example, the 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. The controller sends a start signal to make the electrical plug 41 of the docking mechanism 4 dock with the terminal 82 of the upper cover 81 of the compressor 8 under test to achieve automatic testing.

[0049] It is important to understand that, as an example, such as Figure 5 As shown, screw 83 serves as the positioning point sought by sensor 2 during the test. When sensor 2 detects screw 83, the electrical plug 41 on the docking mechanism 4 can mate with the terminal 82 of the upper cover 81 of the compressor under test 8. Thus, by using the rotating component 3 and sensor 2 to assist in positioning the terminal 82, the problem of difficulty in ensuring the accuracy of automatic testing of the docking terminal 82 is solved when the compressor under test 8 is not welded to its upper and lower covers during assembly. Of course, other positions on the upper cover 81 can also be designed as positioning points, as long as it is ensured that when sensor 2 detects the positioning point, the electrical plug 41 and the terminal 82 of the upper cover 81 of the compressor 8 can effectively mate to complete the test.

[0050] Next, in this embodiment, the terminal 82 of the compressor 8 upper cover 81 has both a flat and an inclined state (e.g., Figure 5 As shown, in order to further improve the accuracy of the automatic docking of the plug 41, an angle adjustment mechanism 1 is added and connected to the docking mechanism 4. The angle adjustment mechanism 1 drives the docking mechanism 4 to rotate around the first axis and the second axis respectively. The first axis and the second axis are perpendicular to the rotation axis of the rotating component 3, so that the plug 41 on the docking mechanism 4 can swing to a certain extent to meet the requirements of the terminal 82 in both vertical and tilted states. The angle adjustment mechanism 1 can be used to make it compatible with more models of compressor 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 can be perpendicular to each other or not perpendicular to each other. That is, the angle between the first axis and the second axis can be an acute angle or an obtuse angle, so as to be compatible with the testing of more complex compressor 8 terminal 82.

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

[0053] Also, such as Figure 5 As shown, since the top cover 81 is not welded to the compressor 8 housing, when the test results are abnormal, there is no need to cut or weld the top cover 81 of the compressor 8. The operator can directly lift the top cover 81 to inspect the abnormal parts, which facilitates timely tracing of the problematic process and then direct improvement of the problematic process. This effectively avoids the problem of traditional testing methods where the top cover 81 is welded to the compressor 8 housing for terminal 82 testing, where a problem in a certain process could lead to the risk of scrapping a batch of compressors 8.

[0054] Of course, the testing device in this embodiment does not exclude the testing of the terminal 82 of the compressor 8 after the entire machine is assembled. The sensor 2 and the rotating component 3 quickly locate the positioning point of the compressor 8 under test, efficiently complete the matching and docking of the plug 41 and the terminal 82 of the top cover 81, ensure accurate docking of automated testing, and have an angle adjustment mechanism 1, which can be compatible with the testing of more models of compressor 8 terminal 82.

[0055] This testing device replaces manual testing, and judgments are made through detection equipment. However, human subjective judgment can lead to misjudgments and omissions.

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

[0057] Furthermore, sensor 2 employs a laser sensor. The left and right tilting drive 13 is connected to the connecting plate 42 via the left and right tilting block 14. The laser sensor is installed on the side of the connecting plate 42 with the power plug 41 installed below the connecting plate 42. The laser sensor is used for positioning.

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

[0059] In practical applications, the compressor 8 cover 81 is not welded during the assembly process. During assembly, the compressor 8 cover 81 is offset relative to the center of the housing. Before testing, the center of rotation of the rotary motor 32 is adjusted to be consistent with the center of the compressor 8 housing. Based on the principle of center offset, laser positioning is applied. The laser sensor emits a laser point. Using the principle of laser emission, the rotary motor drives the laser sensor to rotate. The screw 83 is relatively high. After rotating to the position above the screw 83, positioning stops. The plug 41 is used to connect to the compressor 8 terminal 82 after positioning. The relative position of the compressor 8 screw 83 and the terminal 82 is fixed.

[0060] In an alternative embodiment, sensor 2 can be a color mark sensor, with a color mark sensor positioned at the positioning point of compressor 8 to detect and identify color marks. Thus, as the rotary motor 32 drives the color mark sensor to rotate, the color mark sensor detects the positioning point, and the electrical plug 41 of the docking mechanism 4 aligns with the terminal block 82 of the compressor 8's upper cover 81, enabling automatic docking testing.

[0061] Sensor 2 can also be other sensors or devices, as long as it is ensured that when sensor 2 detects the positioning point on compressor 8, the electrical plug 41 and terminal 82 are accurately aligned.

[0062] Typically, during the production and assembly of compressor 8, the system records compressor 8 information, including compressor 8 model, terminal 82 tilt information, etc. Before testing compressor 8 terminal 82, the operator pre-adjusts the angle adjustment mechanism 1 based on the compressor 8 information, specifically adjusting the rotation of the front-to-back tilting component and the left-to-right tilting component to adjust the tilt angle of the electrical plug 41 on the docking mechanism 4. This ensures that after the sensor 2 detects the positioning point of compressor 8, the electrical plug 41 and terminal 82 are precisely aligned, ideally with the positioning point located on the upper cover 81.

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

[0064] Due to factors such as the lack of welding and fixing of the top cover 81 and the different placement of the compressor 8 on the conveyor line, the tilt angle of the power plug 41 is pre-adjusted, and then the sensor 2 and the rotating component 3 are used to quickly locate the positioning point and quickly complete the docking of the power plug 41 with the terminal block 82, thereby improving the reliability and accuracy of automated test docking.

[0065] During the automatic test of the vertical terminal 82, the front-to-back tilting component and the left-to-right tilting component are in their initial positions, and the tilt angle of the plug 41 does not need to be adjusted. At this time, the plug 41 is in a vertical state. After the sensor 2 detects the positioning point set in advance on the upper cover 81, such as the screw 83, the plug 41 is exactly above the terminal 82. By controlling the displacement adjustment mechanism 7, the angle adjustment mechanism 1, the rotation component 3 and the docking mechanism 4 are moved downward as a whole, so that the plug 41 effectively contacts the terminal 82, and the test item of the compressor 8 terminal 82 is completed.

[0066] Furthermore, such as Figure 3 As shown, the forward and backward tilting assembly includes a forward and backward tilting drive 11 and a forward and backward tilting block 12, and the left and right tilting assembly includes a left and right tilting drive 13 and a left and right tilting block 14. The forward and backward tilting drive 11 is connected to the rotating assembly 3 through the forward and backward tilting block 12, and the left and right tilting drive 13 is connected to the forward and backward tilting drive 11 through the left and right tilting block 14. The forward and backward tilting motor and the left and right tilting motor are fixedly connected to the rotating assembly 3 as a whole through the forward and backward tilting block 12 and the left and right tilting block 14. The rotating assembly 3 drives the forward and backward tilting assembly and the left and right tilting assembly to rotate together.

[0067] Furthermore, the output end of the forward and backward tilting drive 11 is connected to a first swing head 15, which is fixedly connected to the left and right tilting block 14. The output end of the left and right tilting drive 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 tilting drive 11, i.e., the first axis, so that the left and right tilting components and the docking mechanism 4 rotate around the first axis as a whole, thereby adjusting the angle between the central axis of the plug 41 and the rotation axis of the rotating component 3 or the central axis of the compressor 8 housing within a certain range.

[0069] The second swing head 16 is driven to rotate around the rotation axis of the left and right tilting drive 13, i.e., the second axis, by the left and right tilting drive 13, so that the docking mechanism 4 rotates around the second axis, and the angle between the central axis of the plug 41 and the rotation axis of the rotating component 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-to-back tilt drive 11 and the left-to-right tilt drive 13 increases the tilt angle adjustment range of the electrical plug 41, making it suitable for docking tests with terminals 82 of different models of compressors 8. In this embodiment, the rotation axis / first axis of the front-to-back tilt drive 11 and the rotation axis / second axis of the left-to-right tilt drive 13 are perpendicular to each other, enabling the tilt angle adjustment of the electrical plug 41 in the X and Y directions.

[0071] Furthermore, the front and rear tilting blocks 12 are provided with a first mounting groove 121 to accommodate the rotation of the first swing head 15, and the left and right tilting blocks 14 are provided with a second mounting groove 141 to accommodate the rotation of the second swing head 16.

[0072] Furthermore, the forward and backward tilting drive 11 and the left and right tilting drive 13 are oscillating motors.

[0073] In practical applications, the swing angles of the forward and backward tilting drive 11 and the left and right tilting drive 13 are both 180°. The forward and backward tilting drive 11 drives the electrical plug 41 to swing to a certain extent through the first swing head 15 and the left and right tilting drive 13 drives the second swing head 16, so that the tilt angle of the electrical plug 41 is consistent with the tilt angle of the terminal 82 of the compressor 8 cover 81, thereby improving the accuracy of automated test docking.

[0074] In some embodiments, the testing device further includes a gripper mechanism for positioning the compressor 8. The gripper mechanism has a first gripper assembly 5, which has a first positioning block 51 and a positioning buckle 52. The first positioning block 51 has a first contour groove 511 that matches the contour of the compressor 8 housing. The positioning buckle 52 is fixedly connected to the first positioning block 51 and has a contour block that clamps the distributor bracket 84.

[0075] The first gripper assembly 5 is positioned near the distributor bracket 84 of the compressor 8. The distributor bracket 84 of the compressor 8 is positioned by the first gripper assembly 5, thereby positioning one side of the compressor 8 housing. At the same time, the compressor 8 is positioned in a limited manner during automated testing. The other side of the compressor 8 can be positioned using the existing structure, so that the position of the compressor 8 is fixed when the terminal block 82 is connected to the electrical plug 41 for testing.

[0076] In a specific example, the gripper mechanism also includes a second gripper assembly 6, with the first gripper assembly 5 and the second gripper assembly 6 disposed opposite to each other. The second gripper assembly 6 is provided with a second positioning block 61, and the second positioning block 61 is provided with a second contour groove that matches the profile of the compressor 8 housing.

[0077] The compressor 8 is positioned by using the first gripper assembly 5 and the second gripper assembly 6 which are positioned relative to each other, thus avoiding the compressor 8 shaking or becoming unstable during the automatic testing process, which would affect the accuracy of the connection between the terminal 82 and the electrical plug 41.

[0078] For example, the first gripper mechanism includes a positioning buckle 52, a first positioning block 51, a cylinder, and a fixing device for positioning. The second gripper mechanism, relative to the first gripper mechanism, does not have a buckle but 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 contour grooves to match and clamp the compressor 8 housing.

[0079] The gripper action is as follows: after detecting the compressor 8's arrival, the second gripper assembly 6 moves first to reach the rear of the compressor 8, followed by the first gripper assembly 5. As they approach the compressor 8, the positioning buckle 52 contacts and positions itself against the distributor bracket 84 of the compressor 8. Then, the compressor 8 is pushed to the second positioning block 61 of the second gripper assembly 6 and secured, completing the gripper action. The structure of the distributor bracket 84 differs for different compressor models 8, and the positioning buckle 52 will also be replaced accordingly.

[0080] Example, Figure 5 and Figure 6 The image shows the manufactured compressor 8, which is currently in the assembly process. The compressor 8 includes a distributor bracket 84, a screw 83, and a terminal block 82. The distributor bracket 84 connects to the positioning buckle 52 for positioning and fixing the compressor 8. The screw 83 is used for laser sensor positioning. The terminal block 82 connects to the electrical plug 41 for power-on start-up testing.

[0081] Figure 8 This is a schematic diagram of the electrical plug 41 used to connect to the terminal 82 of the compressor 8. Since the bottom of the terminal 82 is an insulating glass body, excessive force during connection can easily damage the glass body. The electrical plug 41 contains multiple elastic probes 411. The elastic probes 411 can extend and retract to a certain extent along the central axis of the terminal 82 to ensure effective connection between the elastic probes 411 and the terminal 82, while also better protecting the terminal 82 of the compressor 8 during connection.

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

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

[0084] The docking mechanism 4 is used to dock with the terminal 82 of the compressor 8. The up-down adjustment unit 71 is fixed above the frame 9 by the up-down mounting plate 72. The up-down adjustment unit 71 includes a linear motor and an adjustment guide rail (the same as other adjustment units) and is used to provide power when the docking mechanism 4 moves up and down to dock with the terminal 82 of the compressor 8 cover 81.

[0085] The vertical adjustment unit 71 is connected to the horizontal adjustment unit 74 via the vertical connecting block 73. The horizontal adjustment unit 74 is used to adjust the horizontal movement of the docking mechanism 4. The horizontal adjustment unit 74 is connected to the front-back adjustment unit 76 via the horizontal connecting block 75. The front-back adjustment unit 76 is used to adjust the front-back movement of the docking mechanism 4.

[0086] In practical applications, the front and rear adjustment unit 76 is connected to the rotary motor 32 of the rotating assembly 3 via the front and rear connecting blocks 77. The rotary motor 32 drives 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 11 via the rotating mounting plate 31. The front and rear tilting drive 11 is connected to the left and right tilting drive 13 via the front and rear tilting blocks 12. Since the terminals 82 of the compressor 8 have both flat and tilted states, the front and rear tilting drive 11 and the left and right tilting drive 13 allow for a wider range of adjustable tilt angles of the electrical plug 41, making it compatible with more compressors 8.

[0087] The laser sensor detection principle, the controller receiving the laser sensor's detection signal, and the control of the displacement adjustment mechanism to move downward based on the laser detection signal can be implemented using existing computer programs. Furthermore, the controller's determination of whether the detection signal has detected the positioning point can be implemented using existing simple logic circuits.

[0088] A touch screen button box 91 is installed on the rack 9. The touch screen button box 91 is installed in the middle of the right side of the rack 9. It is used to install the equipment touch screen and buttons, so that employees can control the overall operation of the equipment through the touch screen and buttons.

[0089] The automatic testing process for compressor terminal 82 includes the following steps:

[0090] Before starting the commissioning, the operator adjusts the front and rear adjustment unit 76, the left and right adjustment unit 74, the front and rear tilting motor, and the left and right tilting motor according to the position of the terminal 82 of different compressor models. During the test, the above mechanisms do not move.

[0091] Figure 5 After the compressor 8 shown is in place, Figure 4 The first gripper assembly 5, as shown, actuates to perfectly align the first positioning block 51 and positioning buckle 52 with the distributor bracket 84 on the compressor 8, positioning them as shown. Figure 7 As shown, after the first gripper assembly 5 positions one side of the compressor 8, it pushes the compressor 8 toward the oppositely positioned second gripper assembly 6. The first positioning block 51 and positioning buckle 52 of the first gripper assembly 5, together with the second positioning block 61 of the second gripper assembly 6, fix the compressor 8.

[0092] After the compressor 8 is positioned, the rotary motor 32 of the rotating component 3 drives the laser sensor to locate the compressor 8. Once the screw 83 of the compressor 8 is found, the up-down adjustment unit 71 moves the docking mechanism 4 downward, and the power plug 41 makes perfect contact with the terminal 82 of the compressor 8. The equipment is powered on and begins testing. The touch screen in the touch button box 91 displays the current test status. If an abnormality is detected, the equipment alarms and waits for manual handling. If the test shows normal, the test is completed. The up-down adjustment unit 71 moves the docking mechanism 4 upward, returning to the initial point. The gripper mechanism releases the compressor 8, and the automatic testing function is completed.

[0093] Using this automatic testing device, the process flow is as follows: adjust the position of the docking mechanism 4 - position, locate and dock - power on to start testing - after the test is qualified, the device mechanism returns to the origin - compressor 8 flows away. Compared with the original manual testing, 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.

[0094] The main functions of this utility model are:

[0095] 1. Applied to automatic terminal docking test during compressor assembly process, it uses sensors and rotating components to locate the positioning point, ensuring perfect docking between the plug and the terminal, and improving the accuracy of automatic docking.

[0096] 2. The testing process uses the first positioning block and positioning buckle of the first gripper assembly to position the liquid dispenser bracket, and works with the second gripper assembly to achieve effective limiting during automatic compressor testing.

[0097] 3. An angle adjustment mechanism is added, which uses forward and backward tilting drive components and left and right tilting drive components to effectively adjust the tilt angle of the electrical plug. It can adapt to the automated docking test of the terminal block in both vertical and tilted states. In addition, in conjunction with the displacement adjustment mechanism, it can achieve a larger adjustment range and be compatible with the terminal block test of more complex compressor models.

[0098] 4. The use of testing equipment to automate the terminal block connection test can reliably and automatically locate the connection and adjust the position, solving the problem of misjudgment and omission due to subjective judgment in the original testing mode of the industry.

[0099] In summary, any other corresponding modifications made by those skilled in the art after reading this utility model document, based on the technical solution and concept of this utility model without creative mental effort, shall all fall within the scope of protection of this utility model.
