Description

Technical Field

[0001] This application relates to the field of magnetic tile detection, and particularly to a device for testing the inner diameter, height and thrust of motor magnetic tiles. Background Art

[0002] During the assembly process of a brushless cooling fan motor, there is a process of installing multiple magnetic tiles on the rotor. After the magnetic tiles and the rotor are assembled (referred to as "finished product" in this application), referring to Figure 1 , the finished product consists of a rotor 60 and multiple magnetic tiles 70 adhesively attached to the inner wall of the rotor 60. Three positioning holes 80 are provided on the surface of the rotor 60. After the finished product is assembled by automated equipment, it will be conveyed to the next testing process via a conveyor line.

[0003] The finished product needs to be tested for three parameters: inner diameter, height and thrust. The inner diameter refers to the maximum distance between the diagonal magnetic tiles inside the rotor. The height refers to the distance between the lower edge of the magnetic tile and the lower edge of the rotor housing. The thrust refers to applying a certain force in the vertical direction to push the magnetic tile. If the magnetic tile does not fall off the rotor, it is considered qualified.

[0004] The existing testing is carried out by operators using special inspection tools. When the volume of the tested products is large, measurement errors will occur during the long-term testing by operators, and the overall efficiency is low. Summary of the Invention

[0005] In order to improve the testing efficiency and measurement accuracy, this application provides a device for testing the inner diameter, height and thrust of motor magnetic tiles.

[0006] The device for testing the inner diameter, height and thrust of motor magnetic tiles provided by this application adopts the following technical solutions:

[0007] A device for testing the inner diameter, height and thrust of motor magnetic tiles includes a machine body. A conveyor belt is arranged on the machine body. A tray for supporting the finished product is placed on the conveyor belt. At the input end of the conveyor belt of the machine body, there is a first clamping component for grabbing the finished product on the conveyor line onto the tray. Along the conveying direction of the conveyor belt of the machine body, an inner diameter testing component and a height-thrust synchronous testing component are sequentially arranged;

[0008] The inner diameter testing component includes a first central shaft for supporting the rotor, an insertion ring arranged to be lifted and lowered on the periphery of the first central shaft, and a first driving member for driving the insertion ring to lift and lower. The outer diameter of the insertion ring is the standard inner diameter of the qualified finished product. Above the first central shaft of the machine body, there is a first pressing block arranged to be lifted and lowered, and a second driving member for driving the first clamping block to lift and lower is arranged on the machine body. A second clamping component for grabbing the finished product on the tray onto the first central shaft is arranged on the machine body;

[0009] The height thrust synchronous testing assembly includes a second central shaft that supports and positions the rotor, a contact block disposed around the second central shaft for contacting the magnetic tiles, and a third driving component that drives the second central shaft to rotate vertically. A second clamping block is vertically mounted above the second central shaft, and a fourth driving component is mounted on the machine body to drive the second clamping block to move up and down. A linkage rod is connected to the lower side of the contact block, and a fifth driving component is mounted on the machine body to drive the linkage rod to move up and down. A displacement sensor is mounted on the linkage rod, and the fifth driving component and the linkage rod are connected by a pressure sensor. A third clamping assembly is mounted on the machine body to grip the finished product on the tray onto the second central shaft.

[0010] By adopting the above technical solution, the first clamping component picks up the finished product on the conveyor line and places it on the conveyor belt tray. The conveyor belt transports the finished product to the inner diameter testing component. The second clamping component picks up the finished product on the tray and places it on the first central shaft. At this time, the second driving component drives the first pressing block to press the finished product on the first central shaft. Then, the first driving component drives the insertion block to rise, so that the insertion ring is inserted into the finished product. If the finished product and the insertion ring cannot be inserted, the finished product is unqualified. If there is no obvious shaking after insertion, it is qualified; otherwise, it is unqualified. If the finished product is unqualified, it is removed from the production line. If the finished product is qualified, the second clamping component picks up the finished product and places it on the pallet of the conveyor belt, continuing to convey it to the height thrust synchronous testing component. The third clamping component picks up the finished product and places it on the second central shaft. At this time, the second clamping block descends to clamp the finished product. Then, the fifth drive component drives the linkage rod to rise, causing the abutment block to rise and abut against the magnetic tile. During the process of the linkage rod rising to abut against the magnetic tile, the rising position of the abutment block can be measured using a displacement sensor, which can measure the height of the lower edge of the magnetic tile and the lower edge of the rotor. If the height is within the range, it is qualified. The force applied by the fifth drive component to the linkage rod can be measured using a pressure sensor. When the applied force reaches the set value, the fifth drive component stops moving. At this time, the magnetic tile has not fallen off the rotor, meaning the finished product is qualified; otherwise, it is unqualified. Then, the fifth drive component retracts, and the third drive component drives the second central shaft to rotate, so that the other magnetic tiles correspond to the abutment blocks, and the test is repeated until all magnetic tiles have been tested. If the finished product is qualified, the third clamping assembly picks up the rotor and places it onto a pallet, from where it is conveyed to the next process step by a conveyor belt. Using a fully automated method for testing the finished product helps improve testing efficiency and measurement accuracy.

[0011] Preferably, the first clamping assembly includes a linear slide, a lifting cylinder mounted on the linear slide slide base, and a pneumatic gripper mounted on the piston rod end of the lifting cylinder. The length direction of the linear slide is horizontal and perpendicular to the conveying direction of the conveyor belt.

[0012] By adopting the above technical solution, the lifting cylinder drives the pneumatic gripper to descend and grab the finished product, and then drives the pneumatic gripper to rise. The linear slide is driven by the motor to realize the linear movement of the slide. The slide drives the pneumatic gripper to move towards the conveyor belt until it moves directly above the conveyor belt. The lifting cylinder drives the pneumatic gripper to descend and place the finished product on the pallet, thus realizing the clamping and transfer of the finished product.

[0013] Preferably, multiple insertion rings are provided, and the multiple insertion rings are distributed sequentially along a direction that gradually moves away from the first central axis.

[0014] By adopting the above technical solution, multiple plug-in rings are set, and different plug-in rings correspond to finished products with different inner diameters. That is, the device can be adapted to the testing of finished products with different inner diameters and has strong applicability.

[0015] Preferably, the upper side of both the first central shaft and the second central shaft is provided with a positioning shaft that is inserted into the positioning hole.

[0016] By adopting the above technical solution, the positioning shafts on the first and second central shafts are connected with the positioning holes to achieve the positioning of the finished product, which helps to improve the stability of the finished product during the testing process.

[0017] Preferably, an abutment ring is provided on the periphery of the second central shaft, the abutment block is located between the abutment ring and the second central shaft, and the lower edge of the rotor abuts against the abutment ring; when the abutment block is lowered to the lowest state, the upper surface of the abutment block is flush with the upper surface of the abutment ring.

[0018] By adopting the above technical solution, the lower edge of the rotor abuts against the abutting ring, which provides support for the finished product and positions the lower edge of the rotor. The abutting ring acts as a reference. With the abutting ring as the reference, when the abutting block rises and abuts against the magnetic tile, the displacement of the abutting block is the required test height of the magnetic tile.

[0019] Preferably, the abutment block is detachably connected to the end of the linkage rod.

[0020] By adopting the above technical solution, when the specifications of the magnetic tiles are different, different abutment blocks can be disassembled and replaced to adapt to the testing work of different magnetic tiles.

[0021] Preferably, the abutment ring is rotatably connected to the machine body.

[0022] By adopting the above technical solution, the second clamping block presses the finished product onto the abutment ring. When the second central shaft rotates, it will drive the finished product to rotate. Since the finished product and the abutment ring are pressed together, and the abutment ring is rotatably connected to the machine body, it helps to prevent excessive friction between the finished product and the abutment ring, which would affect the quality of the rotor.

[0023] Preferably, a mounting ring is rotatably connected to the body, the mounting ring is sleeved on the circumference of the second central shaft, and the abutment ring is detachably connected to the mounting ring.

[0024] By adopting the above technical solution, during the test, the lower edge of the rotor is in constant contact with the abutment ring, which will wear out. By utilizing the detachable abutment ring and mounting ring, the abutment ring can be replaced in a timely manner, ensuring the accuracy of the test.

[0025] Preferably, the machine body is provided with a storage plate, the storage plate has a storage slot for storing the abutment block, and the storage plate has a ring groove for storing the abutment ring.

[0026] By adopting the above technical solution, the storage slots are used to store the abutment blocks of different specifications, which facilitates replacement and adapts to the testing of magnetic tiles of different specifications. The ring slots are used to store the abutment rings, which facilitates timely replacement of the abutment rings and ensures the testing accuracy.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. Using automated equipment to test the inner diameter, height, and thrust of magnetic tiles helps improve testing efficiency and accuracy;

[0029] 2. The fifth driving component is connected to the linkage rod via a pressure sensor and a displacement sensor. When the fifth driving component drives the abutment block to abut against the magnetic tile, the height and thrust of the magnetic tile can be measured simultaneously, resulting in higher efficiency.

[0030] 3. With the use of multiple plug-in rings, it can be adapted to the inner diameter test of different specifications of magnetic tiles. By changing different sizes, it can be adapted to the height and thrust test of different specifications of magnetic tiles, making it more versatile. Attached Figure Description

[0038] The following is in conjunction with the appendix Figure 2-6 This application will be described in further detail.

[0039] This application discloses a device for testing the inner diameter, height, and thrust of a motor magnet.

[0040] Reference Figure 2 The testing device for the inner diameter, height, and thrust of motor magnetic tiles includes a body 1, on which a conveyor belt 2 is laid, and a tray 21 supporting the finished product is placed on the conveyor belt 2.

The body 1 is also equipped with a second clamping component 6 and a third clamping component 7 on one side of the inner diameter testing component 4 and the height and thrust testing component, respectively, for gripping the finished product to the testing point for testing.

[0041] Reference Figure 2 and Figure 3The first clamping assembly 3 includes a linear slide 31, a lifting cylinder 32, and a pneumatic gripper 33. A mounting plate 11 is installed on the upper side of the machine body 1 at the input end of the conveyor belt 2. The linear slide 31 is fixedly mounted on the mounting plate 11. The linear slide 31 is driven by a servo motor, and its length direction is horizontal and perpendicular to the conveying direction of the conveyor belt 2. A connecting plate 311 is fixedly mounted on the slide block of the linear slide 31. The lifting cylinder 32 is fixedly mounted on the connecting plate 311 and is vertically downward. The pneumatic gripper 33 is fixedly mounted on the end of the piston rod of the lifting cylinder 32. The pneumatic gripper 33 consists of a bidirectional cylinder and clamping plates mounted on the piston rods at both ends of the bidirectional cylinder.

[0042] The servo motor drives the upper slide of the linear slide table 31 to slide, which in turn moves the lifting cylinder 32, realizing the lateral sliding motion of the pneumatic gripper 33. The operation of the lifting cylinder 32 realizes the lifting and lowering movement of the pneumatic gripper 33. Through the lateral and vertical movement, the finished product is clamped and transferred.

[0043] The structure and principle of the second clamping component 6 and the third clamping component 7 are the same as those of the first clamping component 3, and will not be described in detail in this application.

[0044] Reference Figure 2 and Figure 4 The inner diameter testing component 4 includes a first central shaft 41, a plug ring 42 that is raised and lowered around the first central shaft 41, and a first driving component 43 that drives the plug ring 42 to rise and fall. Three positioning shafts 411 are plugged into the first central shaft 41, which correspond one-to-one with the three positioning holes on the rotor surface, and the positioning shafts 411 are plugged into the positioning holes. The outer diameter of the plug ring 42 is the same as the standard inner diameter of the finished product. The first driving component 43 is a driving cylinder, which is set vertically upward.

[0045] Specifically, a first support plate 12 is fixedly installed on the body 1, a first central shaft 41 is fixedly installed on the first support plate 12, a plug ring 42 is located on the upper side of the first support plate 12, a first fixing plate 13 is provided on the lower side of the body 1, the first fixing plate 13 is connected to the first support plate 12 through a connecting rod, a first driving member 43 is fixedly installed on the first fixing plate 13, a lifting plate 431 is fixedly installed at the piston rod end of the first driving member 43, a plurality of lifting rods 432 are installed on the lifting plate 431 along the vertical direction, the upper end of the lifting rods 432 passes through the first support plate 12 and is fixedly connected to the lower side of the plug ring 42.

[0046] In this application, there are two plug-in rings 42. The outer diameters of the two plug-in rings 42 correspond to different specifications of finished products. The two plug-in rings 42 are nested together. There are two first driving components 43, which drive the corresponding plug-in rings 42 to rise and fall respectively.

[0047] The machine body 1 is provided with a first pressing block 8 on the upper side of the first central shaft 41, and the machine body 1 is provided with a second driving component 81 for driving the first pressing block 8 to move up and down. The second driving component 81 is a driving cylinder, which is fixedly installed on the machine body 1. The piston of the driving cylinder is set vertically downward, and the first pressing block 8 is fixedly installed at the end of the piston rod of the second driving component 81.

[0048] When pallet 21 is conveyed to the first central shaft 41 on conveyor belt 2, the second clamping component 6 clamps the finished product and places it on the first central shaft 41. The finished product is positioned by inserting into the positioning shaft 411 on the first central shaft 41 through the positioning hole. The first clamping block 8 descends to clamp the finished product. Then, the first driving component 43 drives the insertion ring 42 to rise and insert into the finished product. If the finished product cannot be inserted into the insertion ring 42, the finished product is unqualified. If there is no obvious shaking after insertion, it is qualified; otherwise, it is unqualified. Unqualified finished products are removed from the production line directly. Qualified finished products are picked up by the second clamping component 6 and placed on pallet 21, and then conveyed to the height thrust synchronous testing component 5 via conveyor belt 2.

[0049] Reference Figure 2 , Figure 5 and Figure 6 The height thrust synchronous test assembly 5 includes a second central shaft 51 supporting the rotor, an abutment block 52 disposed around the second central shaft 51, and a third driving component 53 driving the second central shaft 51 to rotate vertically. A second support plate 14 is fixedly installed on the body 1, and a rotating disk 9 is fixedly installed on the second support plate 14. The second central shaft 51 is rotatably connected to the upper side of the rotating disk 9. The second central shaft 51 and the first central shaft 41 have the same structure and are both provided with a positioning shaft 411. The third driving component 53 is a rotary motor. A second fixing plate 15 is fixed to the lower side of the body 1. The second fixing plate 15 is connected to the lower side of the second support plate 14 through a connecting rod. The rotary motor is fixedly installed on the second fixing plate 15, and the output shaft of the rotary motor is set vertically upward. The output shaft of the rotary motor is connected to the second central shaft 51 through a coupling, and the coupling on the rotary motor passes through the rotating disk 9 and is rotatably connected to the rotating disk 9 through a bearing.

[0050] The machine body 1 is located above the second central shaft 51 and is equipped with a second pressing block 10 and a fourth driving component 101 for driving the second pressing block 10 to move up and down. The fourth driving component 101 is a driving cylinder and is fixedly installed on the machine body 1. The piston rod of the fourth driving component 101 is set vertically downward, and the second pressing block 10 is fixedly installed at the end of the piston rod of the fourth driving component 101.

[0051] In this application, two abutment blocks 52 are provided, which are symmetrically arranged on both sides of the center of the second central axis 51. Two third fixing plates 16 are provided on the lower side of the body 1, corresponding one-to-one with the two abutment blocks 52. The third fixing plates 16 are connected and fixed to the second support plate 14 through connecting rods. Each of the two third fixing plates 16 is provided with a fifth driving component 20 for driving the corresponding abutment block 52 to rise and fall. The fifth driving component 20 is a driving cylinder, which is set vertically upward. The fifth driving component 20 is fixedly installed on the third fixing plate 16. The piston rod end of the fifth driving component 20 is connected to a linkage rod 30 through a pressure sensor 201. The pressure sensor 201 is a spring-type pressure sensor 201. The linkage rod 30 is set vertically. The upper end of the linkage rod 30 passes through the rotating disk 9, and the end of the linkage rod 30 is fixedly installed with a connecting block 301. The abutment block 52 is detachably connected to the connecting block 301 by bolts. A displacement sensor 302 is also connected to the linkage rod 30.

[0052] A mounting ring 40 is rotatably connected to the second support plate 14 via a plane bearing. The mounting ring 40 is fitted around the circumference of the rotating disk 9. An abutment ring 401 is detachably connected to the mounting ring 40 via bolts. The abutment ring 401 is fitted around the circumference of the rotating disk 9 and abuts against the lower edge of the rotor. Under normal conditions, the upper surface of the abutment block 52 and the upper surface of the abutment ring 401 are at the same horizontal plane.

[0053] The third clamping assembly 7 grips the finished product onto the second central shaft 51. The second clamping block 10 descends, pressing the finished product against the abutment ring 401. Subsequently, the fifth driving component 20 drives the abutment block 52 to rise, where it abuts against the magnetic tile. At this point, the displacement of the linkage rod 30 is the height between the lower edge of the magnetic tile and the lower edge of the rotor housing. The displacement of the linkage rod 30 is collected by the displacement sensor 302 and transmitted to the display module. If the vertical height is within the acceptable range, the finished product is qualified. The fifth driving component 20 continues to move, and the pressure sensor 201 can detect the applied force in real time. When the pressure sensor 201 detects that the applied force has reached the set value, it transmits a signal to stop the fifth driving component 20. Throughout the process, if the magnetic tile does not detach from the rotor, the product is qualified. If either of the above two conditions fails, the product is unqualified.

[0054] Subsequently, the fifth driving component 20 drives the abutment block 52 to reset, and the third driving component 53 drives the second central shaft 51 to rotate at a certain angle, causing the finished product to rotate at a certain angle, so that the other two magnetic tiles move to the top of the abutment block 52 for testing. The above operation is repeated until all magnetic tiles have been tested.

[0055] A storage plate 50 is installed on the body 1. A storage groove 501 for preventing the abutting block 52 is provided in the storage plate 50, and an annular groove 502 for storing the abutting ring 401 is provided in the storage plate 50. When the specifications of the magnetic tiles are different, a new abutting block 52 can be replaced from the storage plate 50 in time and installed on the connecting block 301 to adapt to the testing work of different specifications of magnetic tiles. Since the lower edge of the rotor abuts against the abutting ring 401, when the finished product rotates, friction will inevitably occur between the abutting ring 401 and the lower edge of the rotor. When the edge of the abutting ring 401 is severely worn after a long time, it will affect the actual testing accuracy. Therefore, the testing accuracy can be ensured by timely replacement.

[0056] The implementation principle of a device for testing the inner diameter, height and thrust of a motor magnetic tile in an embodiment of the present application is as follows: The first clamping component 3 grabs the finished product on the conveyor line onto the tray 21 of the conveyor belt 2. The conveyor belt 2 transports the finished product to the inner diameter testing component 4. The second clamping component 6 grabs the finished product on the tray 21 onto the first central shaft 41 and presses the finished product tightly by using the first pressing block 8. Then, the first driving component 43 drives the plugging block to rise, so that the plugging ring 42 is plugged into the finished product. If the finished product and the plugging ring 42 cannot be plugged, the finished product is unqualified. If there is no obvious shaking after the plugging is completed, it is qualified, otherwise it is unqualified. If the finished product is unqualified, the product is taken off the line. If the finished product is qualified, the second clamping component 6 grabs the finished product onto the tray 21 of the conveyor belt 2 and continues to transport it to the height-thrust synchronous testing component 5. The third clamping component 7 grabs the finished product onto the second central shaft 51 and uses the second pressing block 10 to descend and press the finished product tightly. Subsequently, the fifth driving component 20 drives the linkage rod 30 to rise,带动 the abutting block 52 to rise and abut against the magnetic tile. During the process of the linkage rod 30 rising to abut against the magnetic tile, the rising height of the abutting block 52 can be measured by using the displacement sensor 302, and thus the height between the lower edge of the magnetic tile and the lower edge of the rotor can be measured. If the height is within the range value, it is qualified. The force applied by the fifth driving component 20 on the linkage rod 30 can be measured by the pressure sensor 201. When the applied force reaches the set value, the fifth driving component 20 stops moving. At this time, the magnetic tile does not fall off the rotor, that is, the finished product is qualified, otherwise it is unqualified. Subsequently, the fifth driving component 20 retracts, and the third driving component 53 drives the second central shaft 51 to rotate, so that other magnetic tiles correspond to the abutting block 52 and the test is carried out again until all magnetic tiles are tested. If the finished product is qualified, the third clamping component 7 grabs the rotor onto the tray 21 and transports it to the subsequent process for operation by the conveyor belt 2. Testing the finished product in a fully automatic manner helps to improve the testing efficiency and also helps to improve the measurement accuracy.

[0057] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
