[0045] The exemplary embodiments disclosed in the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments disclosed in the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0046] Embodiments of the present invention Figure 1As shown, the tubular motor automatic detection platform includes a frame 10, an operating platform 20 horizontally arranged on the frame 10, and an electric control module 30 arranged on the frame 10. The frame 10 may also be provided with a display module 40. The operating platform 20 is provided with a support bracket 1, and the support bracket 1 is used to horizontally place the motor 50 to be tested. The two ends of the motor 50 to be tested, one end is provided with a travel module, the end is fixed by a fixing bracket 60, and the other end is connected to a linkage shaft 2.

[0047] The linkage shaft 2 is horizontally arranged in the same direction as the motor 50 to be tested, and the linkage shaft 2 can move horizontally. One end of the linkage shaft 2 is provided with a hole to connect the output shaft of the motor 50 to be tested, and rotates synchronously with the output shaft of the motor 50 to be tested. The other end of the linkage shaft 2 is connected to a driving component, and the driving component can drive the linkage shaft 2 to rotate and move horizontally. The power supply end or the functional end of the motor 50 to be tested is connected to the electric control module 30 on the automatic detection platform through a connecting line, which is used to supply power to the motor 50 to be tested and measure the performance parameters of the motor to be tested. The electric control module 30 is also connected to the driving component of the linkage shaft 2, which is used to control the rotation and horizontal movement of the linkage shaft 2.

[0048] An adapter block is provided at one end of the linkage shaft 2. A hole matching the output shaft of the motor 50 to be tested is provided on the adapter block. The adapter block can be replaced according to the different sizes of the output shaft of the motor to be tested.

[0049] The driving component can drive the linkage shaft 2 to rotate. When the driving component does not drive the linkage shaft 2, the linkage shaft 2 can rotate arbitrarily, that is, the supporting component of the linkage shaft 2 gives it as little friction as possible. Therefore, when the linkage shaft 2 is connected to the output shaft of the motor 50 to be tested, the no-load state of the motor 50 to be tested can be simulated. At this time, by detecting the rotation speed, angular velocity, or torque of the linkage shaft 2, the no-load rotation speed, angular velocity and torque of the motor 50 to be tested can be obtained, and various performance parameters of the tubular motor under no-load can be obtained. The driving component 4 gives the linkage shaft 2 a rotation torque in the opposite direction of the rotation direction of the motor 50 to be tested. After the linkage shaft 2 is connected to the motor 50 to be tested, the load state of the motor 50 to be tested can be simulated. At this time, by detecting the rotation speed, angular velocity, or torque of the linkage shaft, various performance parameters of the motor 50 to be tested under load can be obtained. In order to measure the rotation speed of the linkage shaft 2, a plurality of sensors can be arranged on the linkage shaft 2 and connected to the electric control module 30. By reading the data of the sensors, the parameters of the linkage shaft 2 and the motor 50 to be tested can be known. The sensors can include, but are not limited to, angle sensors, rotation speed sensors, and the like.

[0050] One end of the motor 50 to be tested, i.e., the end with the travel switch module, is provided with a square connecting column 521, and the fixing bracket 60 is provided with a connecting hole 61 matching the square connecting column, which is used to fix the motor 50 to be tested. A horizontal guide rail 21 extending laterally is provided at a position corresponding to the fixing bracket 60 on the frame 10, so that the fixing bracket 60 can move along the horizontal guide rail 21. When at least two groups of parallel and spaced support brackets 1 are provided on the operating platform 20, the extension direction of the support brackets 1, i.e., the extension direction of the motor 50 to be tested is perpendicular to the horizontal guide rail 21, i.e., the at least two groups of support brackets 1 are spaced apart along the length direction of the horizontal guide rail 21. Therefore, when multiple groups of support brackets 1 are provided, the multiple groups of support brackets 1 are spaced apart and parallel along the length direction of the horizontal guide rail 21, i.e., a plurality of workstations are formed, and the multiple workstations include at least one detection workstation and at least one workstation to be tested. The fixing bracket 60 can be moved along the horizontal guide rail 21 to one side of the support bracket 1 of the testing station, and then fix the motor to be tested. The testing station can place a spare motor to be tested to facilitate the workers to perform various manual operations for the motor to be tested.

[0051] The operating platform 20 is also provided with at least two groups of connecting sockets and a corresponding number of start buttons. The connecting sockets are provided with various connecting wires for electrically connecting to the motor 50 to be tested. The number of connecting sockets and start buttons corresponds to the number of supporting brackets 1, that is, the number of workstations.

[0052] During the process of automatic testing of the motor to be tested on the testing station, another motor to be tested can be placed on the testing station, and the various connection lines and the start button corresponding to the testing station can be connected to the motor to be tested on the testing station. After the motor test on the testing station is completed, the motor on the testing station can be interchanged with the motor on the testing station that has been connected with the connection line and the start button, and then the motor to be tested on the testing station can be directly tested. The motor on the testing station has been tested at this time, and the connection line and the start button can be removed, that is, the removal step, and then the next motor to be tested is placed in the testing station and the connection step of the connection line and the start button is carried out. In this way, the time for placing and removing parts and connecting and disconnecting the wires of the motor to be tested overlaps with the time of the automatic detection step of another motor to be tested, which reduces the time of the overall detection and improves the detection efficiency.

[0053] A stroke test module 3 is provided below one side of the fixed bracket 60 on the operating platform 20. The stroke test module 3 includes a vertical movable bracket 31 arranged on the frame 10, and an adjusting rod 32 connected to the vertical movable bracket 31. The adjusting rod 32 can move up, down, left and right in a vertical plane with the vertical movable bracket 31, and then align with the adjusting screw hole 51 on the stroke module of the motor 50 to be tested.

[0054] like Figure 2 ,3 As shown, the stroke module of the motor 50 to be tested includes two end covers 52 that are engaged with each other to form an accommodating space, the adjusting screw hole 51 is provided on the end cover 52, and an inner gear sleeve 53 is provided on one side of the end cover 52, and a tooth profile 531 is provided on the inner circumferential surface of the inner gear sleeve 53. The stroke module also includes a connecting sleeve provided on one side of the inner gear sleeve 53 relative to the end cover 52, the connecting sleeve has been omitted in the figure, one end of the connecting sleeve is located on the inner side of the inner gear sleeve 53, and is fixedly connected to the end cover 52. A long gear 54 is provided with a coaxial connecting gear 541, and the connecting gear 541 is meshed with the inner gear sleeve 53. Therefore, driving the inner gear sleeve 53 can drive the long gear 54 to rotate. Two separate screw rods 55 are respectively provided on both sides of the long gear 54. The tooth profiles of the two separate screw rods 55 are set oppositely, and nuts 56 are respectively sleeved on the screw rods 55. The nuts 56 are meshed with the long gear 54. The rotation of the long gear 54 around the axis can drive the two nuts 56 to move in two opposite directions along the screw rods 55. One end of the screw rod 55 is fixedly connected to the end cover 52, and the other end is fixedly connected to a connecting plate 57 which is arranged parallel to the end cover 52 and spaced apart. A travel switch is arranged on the other side of the connecting plate 57. A driving sleeve 58 is sleeved on the end of the screw rod 55 connected to the connecting plate 57. A spring 59 is sleeved on the screw rod 55 between the driving sleeve 58 and the connecting plate 57. A driving rod 581 is connected to one side of the driving sleeve 58. The driving rod 581 extends along the length direction of the screw rod 55 and passes through the hole on the connecting plate 57 to align with the travel switch on the other side of the connecting plate 57. When the nut 56 moves to one end of the screw rod 55 and collides with the driving sleeve 58, the driving sleeve 58 compresses the spring 59 and then drives the rod 581 to move toward the travel switch to start the travel switch, thereby cutting off the power supply to the motor. Figure 3 As shown, an adjusting screw 511 is provided in the adjusting screw hole 51 in the end cover 52, and the outer surface of the adjusting screw 511 is provided with a tooth shape, which meshes with the screw 55. By rotating the adjusting screw 511, the adjusting screw 55 can be rotated, and then the nut 56 rotates along the screw 55, thereby adjusting the initial position of the travel switch.

[0055] The screws 55 on both sides of the stroke module have opposite thread directions. Therefore, when the motor to be tested rotates forward or reversely, the nuts 56 on the screws 55 on both sides limit the end points of the two rotation directions respectively. Because there is a set of screws, nuts and adjustment screws on both sides of the stroke module, there is also an adjustment screw hole 51 on both sides to match it, which is a first adjustment screw hole and a second adjustment screw hole.

[0056] The adjustment rod 32 of the stroke test module 3 is inserted into the adjustment screw hole 51, and can drive the rotation of the adjustment screw 511 through its own rotation. Figure 4As shown, one end of the adjustment rod 32 is connected to the first drive motor 34 through a torque meter 33, and the first drive motor 34 is used to drive the adjustment rod 32 to rotate forward and reverse around the axis. The torque meter 33 can preset its torque strength in advance. If the resistance is too large when adjusting the initial position of the travel switch through the adjustment rod 32, that is, when the adjustment screw 511 is inserted into the adjustment screw hole to drive the adjustment screw 511 to rotate, the torque meter will be overloaded and slip, and the connection between the adjustment rod 32 and the first drive motor 34 will be disconnected, so that the first drive motor 34 will idle, and the first drive motor 34 will not be able to drive the rotation of the adjustment rod.

[0057] An inner gear sleeve test module 4 is provided above one side of the fixed bracket 60 on the operating platform 20. Figure 5 As shown, it includes a connecting bracket 41 connected to a fixed bracket 60, and an inclined connecting bracket 42 inclinedly arranged on the connecting bracket 41, an inclined track 43 is arranged on the inclined connecting bracket 42, and a moving plate 44 connected to the track 43 and capable of moving along the inclined track 43 is arranged, and a driving component 45 for driving the moving plate 44 to move along the track 43 is also arranged on the inclined connecting bracket 42, and a pulley 441 and a belt 442 sleeved on the outer side of the pulley 441 are also arranged on the moving plate 44. The second driving motor 46 is fixedly arranged on the moving plate 44, and its output shaft is fixedly connected to the rotating shaft of one of the pulleys 441, so that the second driving motor 46 can drive the pulley 441 to move. The pulley 441 includes four pulleys separately arranged on the moving plate 44, and the belt 442 is arranged along the pulley 441. The moving plate 44 is provided with a gap between the two pulleys 441 at the lower end thereof, and the belt 442 at the gap position is a driving part 4421 exposed from the moving plate 44, and driven by the moving plate 44, the belt 442 can be pressed downward against the inner gear sleeve 53 of the stroke module to fix the inner gear sleeve 53, or drive the inner gear sleeve 53 to rotate, and can also be driven away from the inner gear sleeve 53 by the moving plate 44. The inner gear sleeve test module 4 can be fixedly connected to the fixed bracket 60, and thus can move along the horizontal guide rail 21 with the fixed bracket 60.

[0058] The tubular motor automatic detection platform can not only automatically detect various performance parameters of the tubular motor when it is unloaded and loaded. The detection steps are as follows: Figure 6 shown.

[0059] 1. Preparation process: put the motor 50 to be tested into the testing station, that is, put it into the supporting bracket 1, fix the end of the motor 50 to be tested through the fixing bracket 60, connect various connection lines of the motor 50 to be tested, and connect to the start button.

[0060] 2. Start the motor to be tested and rotate the output shaft of the motor to be tested, so that the linkage shaft 2 moves horizontally toward the output shaft of the motor to be tested 50, so that the motor output shaft is inserted into the hole of the linkage shaft 2, so that the motor to be tested 50 drives the linkage shaft 2 to rotate together.

[0061] 3. No-load test. At this time, the weight of the linkage shaft and its own resistance are negligible. The specific no-load test steps include:

[0062] 3.1 To test whether the motor is rotating correctly, you only need to determine whether the rotation direction of the linkage shaft after being driven by the motor to be tested is correct; at this time, if the rotation direction is wrong, an alarm will be issued.

[0063] 3.2 Test the no-load speed. At this time, the linkage shaft is set so that its own resistance can be ignored.

[0064] 3.3 Test the travel adjustment function and travel switch function on one side, specifically:

[0065] 3.3.1 The stroke test module 3 is started, and at the same time the internal gear sleeve test module 4 is started. The belt 442 in the internal gear sleeve test module presses down the internal gear sleeve 53 of the motor 50 to be tested, so that the internal gear sleeve 53 is fixed. This step is a preparation step.

[0066] 3.3.2 Insert the adjustment rod 32 into the first adjustment screw hole in the stroke module of the motor to be tested, rotate it forward until it touches the stroke switch, and detect whether the motor to be tested stops running; if the motor to be tested is still powered on after the stroke switch is touched, it means that the function of the stroke switch is damaged. Here, the rotation of the adjustment rod causes the nut to move along the adjustment rod, and then drives the driving rod to touch the stroke switch in the forward direction, and the other rotation direction is the reverse direction. The forward directions of the adjustment rods 32 on both sides are opposite.

[0067] 3.3.3 Then the adjusting rod 32 is reversed to detect whether the motor to be tested is restarted, and then the belt in the internal gear sleeve test module drives the internal gear sleeve 53 to rotate until it touches the travel switch to detect whether the motor to be tested stops running.

[0068] 3.3.4 The adjusting rod 32 is reversed again to restart the motor to be tested.

[0069] The above steps 3.1 and 3.2, as well as step 3.3.1 and step 3.3.2 can be performed simultaneously.

[0070] 4. Carry out a load detection step. In this step, a torque opposite to the rotation direction of the output shaft of the motor to be tested is loaded on the linkage shaft to simulate the load state of the motor to be tested.

[0071] 4.1 Test the voltage, current, power, speed and other parameters of the motor under load.

[0072] 4.2 Under load, rotate the adjustment rod forward until it touches the travel switch and the motor stops running; then the adjustment rod is reversed and the motor to be tested restarts; during this process, if the resistance to rotating the adjustment rod under load is too large, the torque meter will overload and slip, indicating that there is a problem with the travel adjustment function of the motor to be tested under load. Steps 4.1 and 4.2 can be performed simultaneously.

[0073] 4.3 Test the braking performance of the motor after the system is powered off, that is, test whether the rotation angle of the motor output shaft following the load exceeds the limit value after power failure. The above steps can be tested at least twice. At the same time, the adjustment rod 32 is inserted into the second adjustment screw hole in the stroke module of the motor to be tested.

[0074] 5. Perform the second no-load test step, in which the second adjustment screw hole in the stroke module is tested, that is, the stroke adjustment function and the stroke switch function on the other side are tested.

[0075] 5.1 Turn the adjustment lever forward until it touches the travel switch to check whether the motor to be tested stops running.

[0076] 5.2 Then the adjusting rod 32 is reversed to restart the motor to be tested.

[0077] The above step 5, i.e., repeating the above steps 3.3.2-3.3.4, is only for the second adjusting screw hole, and saves the step of using the belt in the internal gear sleeve test module to drive the internal gear sleeve 53 to rotate until it touches the travel switch.

[0078] 6. After the test is completed, the adjusting rod and the internal gear sleeve test module 4 return to their initial positions.

[0079] Furthermore, in the above-mentioned automatic test step, another motor to be tested can be placed at the testing station, and various connection lines of the motor to be tested 50 can be connected to save time for placing and connecting the motor to be tested.

[0080] The above step 6) may also include a dismantling step 7), which is used to remove the various connecting wires of the motor that has been tested. This step 7 can be performed in the testing station or in the station to be tested. After step 6), the various connecting wires and the start button of the tested motor can be directly removed at the testing station, and then the motor on the testing station can be taken away and placed in another motor to be tested to prepare process 1).

[0081] Alternatively, during steps 2)-6) of the above-mentioned motor detection, another motor to be tested may already be placed on the test station, and the connecting wires and the start button may be connected to the other motor to be tested, that is, the step of connecting the connecting wires and the start button in the above-mentioned preparation process 1) may be performed. After the above-mentioned step 6) is completed, the connecting wires and the start button of the tested motor may be directly removed at the detection station, and then the tested motor on the detection station may be taken away, and the motor to be tested to which the connecting wires and the start button have been connected may be placed at the detection station for subsequent detection steps, that is, step 2) may be started directly.

[0082] Alternatively, during steps 2)-6) of the above-mentioned motor detection, another motor to be tested may already be placed on the test station, and the connecting wires and the start button may be connected to the other motor to be tested. After the above-mentioned step 6) is completed, the motors in the test station and the detection station may be directly interchanged. At this time, both motors are connected with the connecting wires and the start button. Then, another new round of detection steps may be performed at the detection station, and at the same time, the connecting wires of the motor that has been tested at the test station may be removed, that is, step 7) may be executed. Then, another untested motor to be tested may be placed in the test station to connect the connecting wires and the start button, and the cycle may be repeated.

[0083] Therefore, the steps of connecting the various connection lines and the start button in the preparation process of step 1) can also be performed in steps 2)-6) of the test of another motor to be tested. Therefore, steps 1) and 7) that require manual operation can be performed when steps 2)-6) of the test of another motor to be tested are being performed, that is, the manual operation steps are performed in the automatic test steps, which saves time and speeds up the test efficiency.

[0084] In the above steps, the motor 50 to be tested is powered on to rotate its output shaft, and the linkage shaft 2 simulates no-load and load states, and the various performance parameters of the motor 50 to be tested are measured through the various connection lines connected to the motor 50 to be tested, and the no-load speed, load speed and output torque of the motor to be tested and other related parameters are measured according to the linkage shaft. While detecting the electrical performance parameters of the load state, the adjustment rod of the stroke test module can be rotated to run until the drive rod touches the stroke switch, thereby disconnecting the power supply of the motor 50 to be tested, and then the adjustment rod is reversed to make the nut and the drive rod retreat, and the power supply of the motor to be tested can be restored. This process is used to detect whether the stroke adjustment function is normal under the load state.

[0085] Disconnect the power supply of the motor 50 to be tested, and the motor stops suddenly to test the braking performance of the motor 50 to be tested. At this time, because the linked rotating shaft still has a load, it can be detected whether the rotation angle of the motor 50 to be tested after power failure exceeds the preset brake slip angle. If it exceeds the preset angle, the braking performance is poor, and the motor brake cannot overcome the inertia of the load in time, and is driven to rotate by the load.

[0086] The belt 442 driving the internal gear sleeve test module moves, thereby driving the internal gear sleeve to move, so that the nut drives the driving rod to touch the travel switch again. This process is used to detect whether the internal gear sleeve is normal.

[0087] The purpose of the stroke detection and the internal gear sleeve function detection is that the motor test system determines that the stroke adjustment function fails or the internal gear sleeve operation fails based on the fact that the motor does not stop running after a certain period of time, that is, the stroke switch is not touched.

[0088] The above test steps can be performed simultaneously, and the steps are reasonably set. It only takes about 35 seconds to test a motor, which greatly saves the test time. Moreover, compared with the original test steps that manually adjust the adjustment rod, it is necessary to subjectively judge whether the resistance is too large when the adjustment rod is adjusted, and it is also necessary to subjectively judge whether the brake rotation angle is too large. The technical solution of the present invention is completely automatically measured by automated components, which not only saves manpower, but also is easier to operate, and the test results are more accurate. Moreover, the setting of such test steps can ensure that the test efficiency is higher, the test results are more accurate, and the test is fully automatic, which can ensure that the test steps are complete, and the test steps will not be missing due to errors in manual operation.

[0089] The tubular motor automatic detection platform can automatically and quickly detect various performance parameters of the tubular motor, such as rotational speed, angular velocity, output torque, braking performance, etc., and can also test whether the stroke adjustment is smooth and whether the internal gear sleeve functions normally when the motor to be tested is loaded or unloaded. The detection process does not require manual adjustment operations, which greatly increases the test efficiency.
