[0058] The following will disclose multiple embodiments of the present invention with the accompanying drawings. For the purpose of clear description, many practical details will be described together in the following description. However, it should be understood that these practical details should not be used to limit the present invention. In other words, in some embodiments of the present invention, these practical details are not necessary. And if it is possible to implement, the features of different embodiments can be applied interchangeably.

[0059] Unless otherwise defined, all words (including technical and scientific terms) used herein have their usual meanings, which can be understood by those familiar with this field. Furthermore, the definitions of the above words in commonly used dictionaries should be interpreted in the content of this specification as consistent with the meanings of the relevant fields of the present invention. Unless otherwise clearly defined, these words will not be interpreted as idealized or overly formal meanings.

[0060] The relationships and terms used in the present invention are explained below:

[0061] Parallelism: The parallelism defined in the present invention is not limited to absolute parallelism. This definition of parallelism can be understood as basic parallelism, which allows for non-absolute parallelism due to factors such as assembly tolerance, design tolerance, and influence of structural flatness. Small angular errors are allowed. For example, an assembly error range of less than 10 degrees can be understood as a parallel relationship.

[0062] Vertical: The verticality defined in the present invention is not limited to an absolute vertical intersection (angle of 90 degrees). It allows for non-absolute vertical intersections caused by factors such as assembly tolerance, design tolerance, and influence of structural flatness. It also allows for errors in a small angle range. For example, the assembly error range of 80 to 100 degrees can be understood as a vertical relationship.

[0063] Ground: The ground defined in the present invention is not limited to a certain material or region, but only a platform for carrying the present invention, and stacking, tilting, and flatness changes are allowed. For example, cement ground, tile ground, work platform, etc. can all be interpreted as ground.

[0064] The above explanation does not completely include the relationship definitions given in the present invention, but only represents a part of the present invention.

[0065] The present invention provides a detection device for the production of permanent magnet synchronous servo motor control boards, which is used to detect the control boards of permanent magnet synchronous servo motors. During the transportation of the control boards, the control boards are clamped and cooperated with the detection component 2 to achieve detection of the control boards.

[0066] like Figure 1-Figure 4As shown, in one embodiment, the detection device includes a body 1 as a main supporting structure, a detection component 2 for detecting the control panel at a detection point of the contact control panel is arranged inside the body 1, the body 1 is placed on the ground, and a conveyor belt 8 is arranged inside the body 1 to change the position of the control panel;

[0067] The detection device also includes:

[0068] The flexible clamping jaw 3 is composed of a plurality of claw teeth 4, each of which is provided with at least two torsion points 15, and the claw teeth 4 change the swing state at the torsion points 15. The claw teeth 4 are provided with elastic bodies 5 on the outside, and the elastic bodies 5 are sleeved / embedded on the outside of the claw teeth 4 and can change the shape according to the swing state of the clamping jaw;

[0069] The base 6 is connected to the conveyor belt 8 and moves with the conveyor belt 8. The flexible clamp 3 is installed on the outside of the base 6. The clamp extends into the inside of the base 6. An electromagnetic component 7 is arranged between the bottom of the clamp and the inner wall of the base 6 to change the height of the clamp compared to the base 6. The control board is located on the inside of the elastomer 5. The height of the clamp changes to tilt the control board.

[0070] In one feasible method, since the welding position between the electronic components and the control board is blocked by the capacitors and other electronic components installed outside the control board, and in order to ensure the accuracy of the contact point between the control board and the detection component 2, the inclination angle of the control board is changed so that the up and down movement of the detection component 2 can stably contact the welding position for functional testing.

[0071] Among them, the clamp uses the torsion point 15 as the swing center, so that the clamp changes to different swing states, and can clamp control panels of different shapes accordingly. In order to ensure the stability of the clamp, the clamp increases the rotation force to ensure that it will not loosen during the clamping process, that is, the swing force of the clamp is increased to be greater than the elastic force of the elastomer 5 clamping the control panel.

[0072] Since the clamping position of the control board is fixed, the control board can be configured to contact the detection component 2 at different angles by utilizing the mutual coordination of the height changes between the multiple claws 4, and the detection component 2 only needs to move up and down according to the coordinates corresponding to the contact point, without adjusting the inclination state or position of the detection component 2, so as to ensure the precise position of the contact point.

[0073] like Figure 13-Figure 15 As shown, in one embodiment, the claw 4 is composed of at least four connecting members 11, the four connecting members 11 are connected in sequence, the end connecting member 11 extends into the inside of the base 6, and the electromagnetic assembly 7 includes at least two first electromagnets 12 respectively installed at one end of the fourth connecting member 11 inserted into the base 6 and a second electromagnet 13 fixed inside the base 6, and the first electromagnet 12 and the second electromagnet 13 change the height of the fourth connecting member 11 through magnetic force cooperation;

[0074] Four connecting members 11 are connected to form three torsion points 15 , and a clamping plate 14 is disposed outside the torsion point 15 . Both sides of the clamping plate 14 extend into the two connecting members 11 forming the torsion point 15 to limit the swing range of the connecting member 11 .

[0075] In one feasible method, the clamping plate 14 is used to limit the swing angle range of the connection position of every two connecting parts 11. When the connecting parts 11 swing to a corresponding angle, it is avoided that the swing angle of a certain torsion point 15 is too large, resulting in the elastic force of the elastic part being greater than the rotation force of the connecting part 11, affecting the stability of the connecting part 11.

[0076] In another embodiment, when the corresponding torsion point 15 swings, in order to further control the swinging state of the clamping plate 14, one end of the clamping plate 14 is fixed inside the clamping plate 14 to limit the position and angle of the clamping plate 14 inside a connecting member 11.

[0077] like Figure 5-Figure 6 As shown, in one embodiment, the detection component 2 includes:

[0078] A detection device 21 is installed inside the body 1. The detection device 21 is equipped with a detection probe 22. The probe 22 is perpendicular to the ground and can move up and down.

[0079] The slide 23 is installed on the inner side of the machine body 1 , and a detection frame 24 is arranged on the outer side of the slide 23 and connected with the screw rod of the slide 23 . The slide 23 drives the detection frame 24 to move up and down.

[0080] In one practicable manner, a probe 22 that can move up and down is used to contact the control board, so that the control board can be inspected by the inspection device 21 .

[0081] Optionally, the detection device 21 is an electronic multimeter, and after the probe 22 obtains corresponding measurement data of the control board, the measurement data is used to analyze the state of the control board.

[0082] like Figure 5-Figure 8 As shown, in one embodiment, a movable mounting plate 25 is disposed inside the detection frame 24, a gap is provided between the mounting plate 25 and the detection frame 24, and a positioning magnet 26 is disposed on the outer wall of the mounting plate 25, the magnetic force between the positioning magnets 26 adjusts the position of the mounting plate 25, a mounting head 27 is disposed at the bottom of the mounting plate 25, a probe 29 is installed inside the mounting head 27, the mounting heads 27 are arranged in an array, and the mounting heads 27 cover the detection range of the control board within the movement range of the mounting plate 25;

[0083] The connecting portion 28 is located on the upper portion of the mounting plate 25 . The probe 22 is inserted into the connecting portion 28 . The connecting portion 28 extends to the inner side of the mounting head 27 and is connected to the probe head 29 .

[0084] In one feasible method, a mounting plate 25 with a certain amount of shaking is used to completely cover the entire detection range of the control board when in use. The position of the probe 29 is adjusted according to different detection positions to achieve detection of the control board at different positions. The setting of the connecting part 28 can connect the probe 22 and the probe 29, so that the position of the probe 29 can be easily adjusted and controlled when the control part is detected.

[0085] The probe 29 is installed in the mounting head 27, and the positioning magnet 26 is used to position the probe 29 to ensure that the position of the probe 29 corresponding to the control board is accurate, thereby ensuring the accuracy and stability of the probe 29. The positioning magnet 26 is an electromagnet.

[0086] like Figure 12-13 As shown, in one embodiment, a top plate 31 is disposed inside the claw 4, the bottom of the top plate 31 is a ball groove 32, a top rod 33 is disposed inside the base 6, the top of the top rod 33 is spherical and fits with the ball groove 32, and the top plate 31 swings relative to the top rod 33;

[0087] A pulling member 34 is disposed at the edge of the top plate 31, and the two ends of the pulling member 34 are respectively connected to the top plate 31 and the connecting member 11. When the connecting member 11 moves up and down, the pulling member 34 changes the tilt angle of the top plate 31, and the tilt angle of the top plate 31 is consistent with the tilt angle of the control panel.

[0088] A positioning rod 35 is disposed on the top of the top plate 31 , and the positioning rod 35 contacts the control panel and supports the control panel.

[0089] In one feasible method, after the claw 4 moves up and down to change the height, the control board will be pulled. In order to ensure that the tilt angle of the control board is consistent with the swing angle of the claw 4, the control board is positioned using a positioning rod 35 to ensure that the swing angle of the control board is consistent with the control angle of the claw 4 on the control board, thereby further improving the docking accuracy between the control board and the probe 29 and avoiding differences in the contact position of the probe 29 and the control board.

[0090] The top plate 31 is connected to the top rod 33 through the ball groove 32, so that the top plate 31 can be free from the restriction of the swing position within a certain range, and the control board is controlled by the swing of the top plate 31, wherein the claws 4, the top plate 31 and the control board move synchronously, and when the swing angle of the control board is adjusted, the accuracy between the movements of the three is guaranteed.

[0091] The control panel is supported by the positioning rod 35 , and the bottom of the positioning rod 35 contacts the control panel to support the control panel, thereby ensuring the bottom position of the control panel.

[0092] like Figure 14-15As shown, in one embodiment, a diaphragm 41 is disposed inside the elastic body 5, the diaphragm 41 is attached to the surface of the elastic body 5, a recess 42 is formed inside the diaphragm 41, and the inner wall of the recess 42 is arc-shaped, the control panel is located at the recess 42, and when the connecting member 11 is at the same height, the axis of the recess 42 is in the same plane parallel to the ground;

[0093] An inner cavity 43 is disposed inside the diaphragm 41 . The inner cavity 43 is located at one side of the recess 42 . When the connector 11 is clamped at the recess 42 , the inner cavity 43 is squeezed.

[0094] In one feasible manner, the control board is positioned using the depression 42 to ensure the planar stability of the control board. Since the control board has different shapes and sizes, the depression 42 is configured as multiple, and the depressions 42 on the inner sides of the multiple claw teeth 4 cooperate with each other to form a stable clamp for the control board.

[0095] The inner cavity 43 configured inside the recess 42, when the control board is inside the recess 42, the middle part of the inner cavity 43 is squeezed, and the medium enters into the two ends of the inner cavity 43, so that the amount of medium at the two ends of the inner cavity 43 increases, and the two sides of the recess 42 protrude outward and contact the control board, thereby further ensuring the stability of the control board.

[0096] Optionally, the elastic member is rubber.

[0097] Optionally, the elastic member is wrapped around the outside of the connecting member 11 , and the diaphragm 41 is respectively connected to the elastic member on the outside of each claw tooth 4 .

[0098] In another embodiment, the elastic member is embedded in the outer side of the connecting member 11 , and the diaphragm 41 connects each elastic member. The diaphragm 41 protrudes outward at the interval between the claw teeth 4 , and the recess 42 is annularly opened on the inner wall of the diaphragm 41 .

[0099] like Figure 9-11 As shown, in one embodiment, the base 6 can be rotatably installed in the middle of the conveyor belt 8, the outer side of the base 6 is provided with teeth 51, and the body 1 is provided with a rack 52 on the side where the control panel is installed inside the claw 4, and the teeth 51 and the rack 52 are meshed to change the rotation angle of the base 6;

[0100] When the teeth 51 are meshed with the rack 52 , the rotation angle of the base 6 is consistent with the spacing angle between the claw teeth 4 .

[0101] In one feasible method, since the control boards are inspected batch by batch and the control boards of the same batch have the same shape, the wear caused by the contact position between the control board and the diaphragm 41 will appear at the same position. The position of the diaphragm 41 is changed by rotating the base 6. When the control board is clamped, the wear of the control board on the diaphragm 41 at the same position is reduced, thereby ensuring the service life of the diaphragm 41.

[0102] Wherein, due to the arrangement of the teeth 51 and the rack 52, the rotation angle of the base 6 is limited by the rotation of the base 6, so that the position of the claw teeth 4 rotates correspondingly, thereby avoiding deviation of the position of the control board.

[0103] like Figure 10-11 As shown, in one embodiment, a torsion spring is arranged between the base 6 and the conveyor belt 8, and the two ends of the torsion spring are respectively connected to the base 6 and the conveyor belt 8, a positioning ball 53 is arranged inside the base 6, and the positioning head protrudes outward, and a positioning hole 54 is arranged on the surface of the conveyor belt 8, and the positioning hole 54 is adapted to the positioning ball 53;

[0104] A support spring 55 is disposed inside the positioning ball 53 to push the positioning ball 53 outward.

[0105] In one feasible manner, by adapting the positioning ball 53 to the positioning hole 54 , the base 6 can be positioned after the base 6 is twisted to ensure the stability of the base 6 after the twisting. Due to the setting of the support spring 55 , the positioning ball 53 is in stable contact with the positioning hole 54 .

[0106] In addition, the number of positioning holes 54 is one less than the number of claw teeth 4, and a torsion spring is used to reset the base 6. When the positioning ball 53 moves to a position other than the positioning hole 54, the positioning ball 53 is squeezed, and after the tooth 51 and the rack 52 are disengaged, the force of the torsion spring resets the base 6, and the inertia of the torsion spring resets the base 6 to reset the base 6.

[0107] The present invention also discloses a detection method for a permanent magnet synchronous servo motor control board, which is used for the above detection device and comprises the following steps:

[0108] The control board is placed inside the flexible clamp 3, and the swing claws 4 clamp the control board;

[0109] The conveyor belt 8 drives the base 6 to move to the position directly below the detection component 2. The detection component 2 contacts the control board to detect the current, voltage and resistance in turn.

[0110] During the movement of the conveyor belt 8, the electromagnetic assembly 7 changes the height of the claw teeth 4 to adjust the tilt angle of the control board for detection.

[0111] In one embodiment, when the conveyor belt 8 drives the base 6 to move, the tilt angle of the control board is determined according to the contact position between the next detection component 2 and the control board, and the fluctuation of the claw teeth 4 is controlled by the change of the magnetic force of the electromagnetic component 7.

[0112] In summary, the technical solutions disclosed in the above embodiments of the present invention have at least the following advantages:

[0113] 1. In the process of detecting electric variables on the control board of the present invention, the inclination angle of the control board is adjusted according to the detection position of the control board, so as to avoid the situation in which the detection component cannot be directly connected to the control board due to the structural particularity of electronic components such as capacitors during the detection process, and further facilitate the detection of the control board.

[0114] 2. Position the control panel by configuring multiple recesses. When installing and clamping the control panel, place the control panel on the upper part of the positioning rod, support the control panel with the positioning rod, and then clamp the control panel to ensure that the control panel, the card plate and the claws are at the same height, thereby ensuring the adjustment accuracy of the control panel.

[0115] 3. When the control board is clamped, the inside of the groove is squeezed, and the inner cavity medium moves, causing the inner cavity medium to move to both sides of the inner cavity. By utilizing the elasticity of the diaphragm and the squeezing of the diaphragm by the medium on both sides of the groove, the diaphragm contacts the control board to clamp the control board, thereby further ensuring the stable position of the control board.

[0116] 4. By using a rotatable base, the contact position between the control board and the diaphragm can be adjusted when the control board is clamped. After the test is completed, the angle of the base is adjusted. After the base is rotated, the contact friction between the control board and the diaphragm can be avoided to prevent excessive wear of the diaphragm.

[0117] Although the present invention is disclosed in conjunction with the above embodiments, it is not intended to limit the present invention. Anyone familiar with this technology can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the definition of the attached claims.
