Technical Field

[0001] This application relates to the field of coil assembly technology, specifically to a positioning mechanism and a coil assembly device. Background Technology

[0002] The existing product requires the assembly of a coil within its cavity. The coil is small, with rounded corners on all four sides, making it impossible for conventional assembly equipment to precisely position its outline. The assembly precision required for the coil within the product cavity is extremely high, and due to limitations imposed by the gaps within the cavity, the coil can currently only be manufactured and assembled on specialized equipment.

[0086] Please see Figure 1 , Figure 1 This is a schematic diagram of the positioning mechanism proposed in an embodiment of this application. The positioning mechanism 100 is used to position the workpiece 200. Figure 1 As can be seen, the positioning mechanism 100 includes a base 10, a sliding member 20, a support member 30, a clamping assembly 40, and a camera module 50.

[0087] The base 10 is used to mount the slider 20, the support 30, and the clamping assembly 40. The slider 20 is slidably disposed on the base 10, that is, the slider 20 and the base 10 are slidably connected. The support 30 is disposed at one end of the slider 20 and is used to support the workpiece 200. The clamping assembly 40 is disposed on the slider 20, and the clamping assembly 40 is held abutted to open or clamp as the slider 20 slides, thereby releasing or clamping the workpiece 200 supported on the support 30. The camera module 50 is disposed opposite to the support 30 and the workpiece 200 supported on the support 30, and the camera module 50 is used to acquire images of the workpiece 200 supported on the support 30.

[0088] Thus, the positioning mechanism 100 clamps the workpiece 200 via the clamping component 40, which facilitates the camera module 50 in acquiring an image of the workpiece 200 and further acquiring its contour. The contour of the workpiece 200 reflects its position in the image acquired by the camera module 50. The camera module 50 compares the acquired contour with a preset contour threshold, which refers to the position of the contour in the image acquired by the camera module 50 when the workpiece 200 is in the correct position. When the acquired contour does not match the preset contour threshold, an external driving component ( Figure 1 (Not shown) The drive base 10, the slider 20 connected to the base 10, the support 30 connected to the slider 20, and the clamping assembly 40 connected to the slider 20 move together, so that the contour of the workpiece 200 acquired by the camera module 50 is consistent with or close to the preset contour threshold, thereby accurately positioning the workpiece 200, so that the workpiece 200 can be assembled in the accurate position, which can improve the assembly accuracy of the workpiece 200, which is conducive to the mass production of the product and reduces the production cost of the product.

[0089] Understandably, the preset contour threshold can also be a standard table. That is, the contour of the obtained workpiece 200 can be mapped onto the standard table through an algorithm. When the contour of the workpiece 200 is mapped onto the standard table and meets the requirements, the workpiece 200 is in the correct position.

[0090] In this embodiment, the workpiece 200 is a coil holder and a coil sleeved on the coil holder. The coil holder is generally a quadrangular prism with rounded corners, and the coil is wound on the coil holder. The positioning mechanism 100 can also be mounted on the coil assembly device via the base 10. Figure 1 On (not shown) or other devices that require positioning.

[0091] The positioning mechanism 100 also includes a light source 52 and an optical path deflection element 54.

[0092] The light source 52 is used to emit a light beam. The light source 52 is disposed on one side of the base 10 and is opposite to the light path deflection element 54. The light beam emitted by the light source 52 can be perpendicularly irradiated by the light path deflection element 54. The light path deflection element 54 is disposed on the sliding member 20 and can move together with the sliding member 20. The light path deflection element 54 is located in the light path of the light beam emitted by the light source 52. The light path deflection element 54 is used to change the propagation direction of the light beam emitted by the light source 52 so that after the propagation direction of the light beam emitted by the light source 52 is changed by the light path deflection element 54, the light beam emitted by the light source 52 can irradiate the workpiece 200 and the camera module 50 supported on the support member 30.

[0093] Thus, the camera module 50 can acquire a clearer image and outline of the workpiece 200. The light beam emitted by the light source 52 is redirected by the optical path deflection element 54 and then shines towards the camera module 50. However, the light beam emitted by the light source 52 is partially blocked by the workpiece 200, meaning only a portion of the light beam reaches the camera module 50. Therefore, the camera module 50 can acquire an image of the workpiece 200 with significant brightness differences and further acquire the outline of the workpiece 200. By comparing the acquired outline of the workpiece 200 with a preset outline threshold, the current position of the workpiece 200 is obtained. When the position does not meet the requirements, the base 10 and the components mounted on the base 10 can be adjusted accordingly using an external driving component.

[0094] In one embodiment, the camera module 50 includes a CCD (Charge Coupled Device) camera and a lens connected to the CCD camera. Two prisms are used as optical path deflection elements 54, which are respectively positioned opposite to the two ends of the workpiece 200 along its length. A light beam emitted from the light source 52 is perpendicularly incident on the prism, and the beam is reflected by the prism and directed towards the camera module 50.

[0095] The positioning mechanism 100 also includes a protective plate 80. The protective plate 80 is generally plate-shaped and is connected to the base 10. The protective plate 80 is used to shield all or part of the base 10, the sliding member 20, and the clamping assembly 40 to prevent external dust and other impurities from entering the interior of the positioning mechanism 100, thereby reducing the positioning accuracy of the positioning mechanism 100.

[0096] Please see also Figure 2 and Figure 3 , Figure 2 This is a schematic diagram of the positioning mechanism after the protective plate has been peeled off according to an embodiment of this application. Figure 3 for Figure 2 An exploded view. A sliding groove 14 is provided on the base 10. The sliding groove 14 is generally a groove that is open at one end and closed at the other end. The sliding member 20 is slidably disposed in the sliding groove 14.

[0097] The sliding member 20 includes a sliding body 201, a sliding limiting part 202, a sliding connecting part 203, and a sliding bearing part 204.

[0098] The sliding body 201 is generally plate-shaped and is disposed within the sliding groove 14. Two sliding limiting parts 202 are respectively disposed at one end of the sliding body 201, forming a support groove 205 between the two sliding limiting parts 202. Two sliding connecting parts 203 are respectively connected to the sliding limiting parts 202, and the sliding connecting parts 203 are generally L-shaped. A sliding bearing part 204 is disposed at the end of the sliding body 201 away from the sliding limiting parts 202, and an optical path deflection element 54 is disposed on the sliding bearing part 204 and located at both ends of the sliding bearing part 204. A portion of the clamping assembly 40 is disposed within the area enclosed by the sliding connecting part 203 and the sliding bearing part 204.

[0099] The positioning mechanism 100 also includes a sliding elastic element 22. The sliding elastic element 22 is located between the end of the slider 20 away from the support 30 and the base 10, and the sliding elastic element 22 is used to provide elastic force to the slider 20.

[0100] In one embodiment, there are two sliding elastic elements 22, and the sliding elastic elements 22 are springs.

[0101] Understandably, in other embodiments, the sliding elastic element 22 may also be other elastic components such as rubber.

[0102] The positioning mechanism 100 also includes a sliding connector 24, through which the sliding member 20 is slidably connected to the base 10. Specifically, limiting holes 12 are provided on both sides of the sliding groove 14 of the base 10; correspondingly, a connecting hole 206 corresponding to the limiting hole 12 is provided on the sliding limiting part 202. There are two sliding connectors 24, which are correspondingly provided to the sliding limiting part 202. One end of the sliding connector 24 is inserted into the connecting hole 206 on the sliding limiting part 202 to connect with the sliding limiting part 202, and the other end of the sliding connector 24 passes through the limiting hole 12 and extends to the side of the base 10 away from the sliding limiting part 202. In this way, the sliding member 20 is slidably connected to the base 10, and the sliding range of the sliding member 20 is limited by the shape of the limiting hole 12.

[0103] Thus, through the cooperation of the sliding elastic element 22 and the sliding connector 24, the sliding elastic element 22 can provide the sliding element 20 with elastic force to move toward the support 30. Due to the shape of the limiting hole 12, under normal conditions, the sliding element 20 and the sliding connector 24 rest at the end of the limiting hole 12 near the support 30, wherein the sliding elastic element 22 is always in a compressed state.

[0104] In one embodiment, the limiting hole 12 is an elongated hole, which limits the sliding range of the slider 20 and prevents the sliding stroke of the slider 12 from exceeding the range.

[0105] Understandably, in other embodiments, the number of sliding connectors 24 may be only one. For example, the limiting hole 12 of the base 10 may be formed in the sliding groove 14, that is, the extending direction of the limiting hole 12 is the same as the direction in which the light beam emitted by the light source 52 illuminates the optical path deflection element 54. A sliding connector 24 is connected to the slider 20 through the limiting hole 12, which can also realize the sliding connection between the slider 20 and the base 10, and the limiting hole 12 can also limit the sliding range of the slider 20.

[0106] The positioning mechanism 100 also includes a support member 60, a support elastic member 62, and a support movable member 64.

[0107] The top support 60 is slidably disposed in the top support groove 205 of the slider 20 in a direction closer to or further away from the support 30. When the top support 60 and the slider 20 move relative to each other, the clamping assembly 40 is held by the top support 60 to open or clamp. That is, when at least one of the top support 60 and the slider 20 slides, the clamping assembly 40 will be held by the top support 60 to open or clamp.

[0108] The top-holding elastic member 62 is connected between the end of the top-holding member 60 away from the support member 30 and the base 10. The top-holding elastic member 62 is used to provide elastic force for the top-holding member 60 to hold the clamping assembly 40, so that there is always an interaction force between the top-holding member 60 and the clamping assembly 40.

[0109] One end of the supporting movable member 64 passes through the base 10 and is connected to the supporting elastic member 62, while the other end of the supporting movable member 64 extends away from the supporting elastic member 62. In this way, the supporting member 60 can be moved by the supporting movable member 64 so that the supporting member 60 supports the clamping assembly 40.

[0110] In one embodiment, the end of the supporting movable member 64 away from the supporting elastic member 62 can be connected to a driving member for driving the supporting movable member 64 to move.

[0111] The clamping assembly 40 includes a first clamping member 42 and a second clamping member 44. A top holding member 60 is disposed between the first clamping member 42 and the second clamping member 44. The first clamping member 42 and the second clamping member 44 are held by the top holding member 60 to move towards or away from each other, thereby realizing the clamping assembly 40 clamping or opening.

[0112] The side of the top holder 60 that contacts the first clamp 42 and the side of the top holder 60 that contacts the second clamp 44 are both inclined surfaces.

[0113] In one embodiment, the support member 60 includes a support body 602 and a support portion 604 connected to the support body 602. The support body 602 is located within the support groove 205 of the slider 20, and the support portion 604 is located on the side of the sliding connector 24 opposite to the sliding limit portion 202. The support body 602 is generally a quadrangular prism, and the support portion 604 is generally a quadrangular frustum. The area of ​​the end of the support portion 604 connected to the support body 602 is larger than the area of ​​the support body 602, and the support portion 604 gradually contracts towards the support member 30.

[0114] In one embodiment, the first clamping member 42 and the second clamping member 44 each include a clamping base 402, a clamping connector 404, and a clamping part 406.

[0115] The clamping base 402 is connected to the sliding member 20 through the clamping elastic member 46. Due to the extensibility of the clamping elastic member 46, the first clamping member 42 and the second clamping member 44 can move towards or away from each other. The side of the clamping base 402 that contacts the top member 60 is an inclined plane parallel to the inclined plane of the top member 60. By designing one side of the clamping base 402 as an inclined plane, it is beneficial to convert the clamping assembly 40 into horizontal movement when it is pushed up and down by the top member 60.

[0116] In one embodiment, the clamping elastic element 46 is a spring.

[0117] Understandably, in other embodiments, the clamping elastic element 46 may also be other elastic components such as rubber.

[0118] The clamping connector 404 is connected to the side of the clamping base 402 away from the top support 60. The clamping connector 404 is generally a structure with an opening facing the top support 60. The opening of the clamping connector 404 and the sliding support portion 204 of the slider 20 form an area for supporting the optical path deflection element 54. The clamping portion 406 is connected to the end of the clamping connector 404 away from the clamping base 402 and is used to clamp the workpiece 200 supported on the support 30. The clamping connector 404 and the clamping portion 406 can move together with the clamping base 402.

[0119] The side of the clamping part 406 that contacts the workpiece 200 is a flat surface adapted to the clamping surface of the workpiece 200, while the side of the clamping part 406 away from the workpiece 200 is a curved surface, and this curved surface protrudes from the clamping connector 404 in at least one direction so that it can be captured by the camera module 50. Thus, the curved surface of the clamping part 406 facilitates the camera module 50 in identifying the workpiece 200 and the clamping part 406.

[0120] The support member 30 includes a support base 32 and a support portion 34 connected to the support base 32.

[0121] The support base 32 is generally plate-shaped and is located at the end of the slider 20 away from the sliding elastic member 22. Two support parts 34 are located at opposite ends of the support base 32 to support the workpiece 200. Thus, by supporting the workpiece 200 with the two support parts 34, the workpiece 200 is suspended in the air, which helps to avoid the influence of other components on the imaging of the workpiece 200 and facilitates the camera module 50 in obtaining a clear image of the workpiece 200.

[0122] The positioning mechanism 100 also includes a limiting member 70, which is generally plate-shaped and is located on the side of the support base 32 away from the sliding member 20. The upper surface of the workpiece 200 supported on the support part 34 is approximately on the same plane as the upper surface of the limiting member 70, thus preventing damage to the workpiece 200 when external devices act on it.

[0123] The positioning process of the positioning mechanism 100 provided in this embodiment is roughly as follows: the top-holding moving member 64 drives the top-holding member 60 to move towards the support member 30. The top-holding part 604 of the top-holding member 60 interacts with the two clamping bases 402 of the clamping assembly 40. The two clamping bases 402 move in opposite directions due to the top-holding action of the top-holding member 60. Correspondingly, the clamping parts 406 connected to the clamping bases 402 also move in opposite directions, and the clamping assembly 40 opens. The workpiece 200 is placed on the support member 34. After the workpiece 200 is placed, the top-holding moving member 64 drives the top-holding member 60 to move away from the support member 30. The clamping bases 402 move towards each other due to the elastic force of the clamping elastic member 46, so that the two clamping parts 406 can clamp the workpiece 200.

[0124] Light source 52 is turned on, emitting a beam of light that perpendicularly illuminates the light path reversing element 54. The beam's propagation direction is changed after passing through the reversing element 54, and the beam illuminates the workpiece 200 and the camera module 50. The camera module 50 acquires an image of the workpiece 200 and obtains its contour based on the characteristics of the beam and the clamping part 406. By comparing the acquired contour with a preset contour threshold, it is determined whether the workpiece 200 is in the correct position. If the position of the workpiece 200 does not meet the requirements, the position of the workpiece 200 is changed by moving the base 10 and the components mounted on it together until the contour of the workpiece 200 acquired by the camera module 50 matches or is close to the preset contour threshold, thereby determining that the workpiece 200 is in the correct position and completing the precise positioning of the workpiece 200.

[0125] Understandably, in other positioning processes, the two clamping parts 406 can also clamp the workpiece 200 in the following way: The sliding connector 24 drives the sliding member and the clamping assembly 40 connected to the sliding member 20 to move away from the support member 30. The two clamping bases 402 of the clamping assembly 40 interact with the top part 604 of the top member 60. The two clamping bases 402 move in opposite directions under the pressure of the top member 60. Correspondingly, the clamping parts 406 connected to the clamping bases 402 also move in opposite directions, and the clamping assembly 40 opens. At the same time, the top member 60 moves away from the support member 30 under the force of the clamping assembly 40. A workpiece 200 is placed on the support 34. After the workpiece 200 is placed, the sliding connector 24 drives the sliding member and the clamping assembly 40 connected to the sliding member 20 to move towards the support 30. The top member 60 no longer interacts with the two clamping bases 406, while the clamping bases 402 move towards each other under the elastic force of the clamping elastic member 46, thereby allowing the two clamping parts 406 to clamp the workpiece 200. At the same time, the top member 60 moves towards the support 30 under the elastic force of the top elastic member 62.

[0126] Understandably, in other embodiments, the sliding connector 24 and the movable top holder 60 can be moved simultaneously, so that the two clamping parts 406 can clamp the workpiece 200.

[0127] Please see Figure 4 , Figure 4 This is a schematic diagram of the structure of a coil assembly device provided in an embodiment of this application. The coil assembly device 1000 is used to assemble a coil into the inner cavity of a product. Figure 4 As can be seen, the coil assembly device 1000 includes the positioning mechanism 100 and the drive assembly 300 as described above.

[0128] The drive assembly 300 is connected to the base 10 of the positioning mechanism 100. The drive assembly 300 is used to drive the base 10, the slider 20 connected to the base 10, the support 30 connected to the slider 20, the clamping assembly 40 connected to the slider 20, and the workpiece 200 clamped by the clamping assembly 40 to move within a preset range.

[0129] In one embodiment, the drive assembly 300 includes a first drive member 310 and a second drive member 320. The first drive member 310 is connected to the base 10 and is used to drive the base 10 and components disposed on the base 10 along a path such that... Figure 4 The movement is along the X-axis direction as shown. The second drive member 320 is connected to the first drive member 310, and the second drive member 320 is used to drive the first drive member 310, the base 10 connected to the first drive member 310, and the components disposed on the base 10 along the X-axis direction as shown. Figure 4The movement is shown in the Y-axis direction. Through the first drive member 310 and the second drive member 320, the workpiece 200 can move within a preset range formed by the X-axis and Y-axis, thereby achieving precise positioning of the workpiece 200.

[0130] The coil assembly device 1000 also includes a heating pressure head (not shown) for heating the workpiece to facilitate assembly. The heating pressure head is positioned opposite to the support member 30 of the positioning mechanism 100 and the workpiece 200 supported on the support member 30. After the positioning mechanism 100 accurately positions the workpiece 200, the coil assembly device 1000 drives the heating pressure head to move to heat the workpiece 200, which facilitates the assembly of the workpiece 200 into the inner cavity of the product.

[0131] The positioning and assembly process of the coil assembly device 1000 provided in this embodiment is roughly as follows: the positioning process of the positioning mechanism 100 as described above, so that the two clamping parts 406 clamp the workpiece 200.

[0132] The light source 52 is turned on, emitting a beam of light that perpendicularly illuminates the light path reversing element 54. After passing through the light path reversing element 54, the beam's propagation direction is changed, illuminating the workpiece 200 and the camera module 50. The camera module 50 acquires an image of the workpiece 200 and obtains its contour based on the characteristics of the beam and the clamping part 406. By comparing the acquired contour with a preset contour threshold, it is determined whether the workpiece 200 is in the correct position. If the position of the workpiece 200 does not meet the requirements, the driving component 300 moves the base 10 and the components mounted on it together within a preset range, changing the position of the workpiece 200 until the contour of the workpiece 200 acquired by the camera module 50 matches or approaches the preset contour threshold, thereby confirming that the workpiece 200 is in the correct position and completing the precise positioning of the workpiece 200.

[0133] After the positioning mechanism 100 accurately positions the workpiece 200, the coil assembly device 1000 drives the heating pressure head to heat the workpiece 200, thereby assembling the workpiece 200 into the inner cavity of the product through other mechanisms of the coil assembly device 1000.

[0134] The above embodiments and accompanying drawings illustrate various implementation methods and expansion possibilities of the positioning mechanism 100 and coil assembly device 1000 provided in this application. Through the above solutions, the assembly accuracy of the workpiece 200 can be improved, which is conducive to the mass production of products and the reduction of product production costs.
