[0018] The present invention is described below based on embodiments, but the invention is not limited to these embodiments. In the detailed description of the invention below, certain specific details are described in detail. Those skilled in the art will fully understand the invention even without these details. To avoid obscuring the essence of the invention, well-known methods, processes, flows, elements, and circuits are not described in detail.

[0021] Figure 1 and Figure 2 These are schematic diagrams of the motor assembly equipment from different directions. Figure 3 This is an exploded view of the motor assembly equipment. (For example...) Figure 1-3 As shown in the figure, the motor assembly equipment includes a first positioning part 1, a second positioning part 2, a third positioning part 3, a support platform 4, a base 5, a first drive part 6, and an ejection part 7. Figure 1The motor assembly equipment shown is in an equipped state, wherein the clamping plate 11, the third positioning surface 21 and the fourth positioning surface 31 extend upward from the support platform 4 and are distributed around the support surface 41.

[0022] Figure 4 and Figure 5 A motor is illustrated. In some embodiments, the motor is, but is not limited to, a linear vibration motor A. The linear vibration motor A is a transmission device that directly converts electrical energy into linear motion mechanical energy without requiring an intermediate conversion mechanism. Specifically, the motion unit A1 in the figure is connected to the housing A3 via spring plates A2 located on both sides. This motion unit A1 is also the oscillator of the linear vibration motor A, which performs linear reciprocating motion relative to the housing A3 under the influence of a magnetic field. Figure 4 The linear vibration motor A is in its pre-assembly state. The housing A3 has side walls and a bottom, and the top of the housing A3 is in an open state. The spring plate A2 is located at both ends of the motion unit A1 in the direction of motion. At the same time, the ends of the spring plate A2 are also provided with pads A21, which facilitate the welding of the spring plate A2 to the housing A3. Figure 5 The linear vibration motor A is in its assembled state. Figure 6 The linear vibration motor A is positioned on the bearing surface 41. In this configuration, the housing A3 covers the top and periphery of the motion unit A1 and the spring plate A2.

[0023] Figure 7 This is a schematic diagram showing the positional relationship between the bearing surface 41 and each positioning part. The diagram illustrates two directions, namely direction X and direction Y. The two directions are perpendicular to each other. Figure 1 The diagram also shows the direction Z, which is perpendicular to both the X and Y directions simultaneously.

[0024] In some implementations, such as Figure 1-3 As shown, the linear motor assembly equipment includes a support platform 4, multiple first positioning parts 1, multiple second positioning parts 2, and a third positioning part 3. The support platform 4 has a horizontally oriented support surface 41. Each first positioning part 1 includes a clamping piece 11, which has a first positioning surface 111 and a second positioning surface 112 that are opposite to each other, with the first positioning surface 111 facing the support surface 41. Each second positioning part 2 has a third positioning surface 21 facing the support surface 41. Each third positioning part 3 has a fourth positioning surface 31 that is opposite to the support surface 41.

[0025] like Figure 7As shown, in the first direction (i.e., direction X), multiple third positioning surfaces 21 are located on both sides of the bearing surface 41, while a fourth positioning surface 31 is operably movable relative to an adjacent third positioning surface 21. Simultaneously, the fourth positioning surface 31 and the third positioning surface 21 engage to form a clamping pair, namely the two sets of fourth positioning surfaces 31 and third positioning surfaces 21 located at the upper left and lower right positions in the figure. In the second direction (i.e., direction Y), multiple first positioning surfaces 111 are located on both sides of the bearing surface 41 and are operably movable relative to the bearing surface 41, wherein the first direction is perpendicular to the second direction. (Refer to...) Figure 4-6 As shown, when the multiple first positioning surfaces 111 and the multiple second positioning surfaces 112 abut against the two sides of the motion unit A1 and the inner wall of the housing A3 respectively, the clamping pair pushes one end of the spring plate A2 to fit against the inner wall of the housing A3, wherein the other end of the spring plate A2 is connected to the motion unit A1.

[0026] Specifically, the second positioning part 2 includes a first positioning block, and a third positioning surface 21 is formed on the first positioning block. The third positioning part 3 includes a second positioning block, and a fourth positioning surface 31 is formed on the second positioning block. The support platform 4 is provided with a through hole, and the second positioning block extends from below the support surface 41 to the side of the support surface 41 through the through hole. In this embodiment, the first positioning block and the second positioning block are used to transmit clamping force.

[0027] Figure 6 The thick solid line represents the outline of the linear vibration motor A, and the thin solid line represents the outline of the linear motor assembly equipment. The arrows in the figure indicate the direction of movement when the fourth positioning surface 31 clamps the motor. The dashed box I in the figure indicates the position of the fourth positioning surface 31 when the push spring plate A2 is in contact with the housing A3.

[0028] In this embodiment of the linear motor assembly equipment, the motion unit A1 is first positioned using the first positioning surface 111 to ensure the positional accuracy of the motion unit A1 in the first direction. Then, the housing A3 is simultaneously positioned using the second positioning surface 112 and the third positioning surface 21, further ensuring the positional accuracy of the housing A3 relative to the bearing surface 41. Thus, on the one hand, the clamping piece 11 is inserted between the motion unit A1 and the housing A3 to create a certain gap between them in the second direction, thereby ensuring that the motion unit A1 can move along the centerline of the housing A3. On the other hand, the third positioning surface 21 and the fourth positioning surface 31, forming the clamping pair, are adjacent to each other, preventing excessive deformation of the housing A3 when one end of the spring piece A2 is attached to the inner wall of the housing A3, thus avoiding impact on the dimensional accuracy of the final product.

[0029] Preferably, a chamfer is provided on the second positioning part 2, which is located at the top of the third positioning surface 21. When the housing A3 is installed into the linear motor assembly equipment along the third positioning surface 21 and the second positioning surface 112, the chamfer can guide the housing A3. At the same time, the distance between the fourth positioning surface 31 and the third positioning surface 21 should be controlled within a certain range to avoid excessive clamping force between them, which would cause deformation of the housing A3.

[0030] Specifically, such as Figure 7 As shown, there are four clamping plates 11, which are paired up on both sides of the bearing surface 41. There are four third positioning surfaces 21, two of which are located on one side of the bearing surface 41, and the other two are distributed symmetrically about the center of the bearing surface 41 by 180 degrees. At the same time, there are two fourth positioning surfaces 31 and two spring positioning pins 42, which are also distributed symmetrically about the center of the bearing surface 41 by 180 degrees.

[0031] Laser welding is a highly efficient and precise welding method that uses a high-energy-density laser beam as a heat source. In this embodiment, laser welding can be used to fix the connection between the housing A3 and the spring plate A2. Figure 4 and 5 The area shown in the image is region II, which represents the laser welding point.

[0032] In some implementations, such as Figure 7 As shown, there are two third positioning parts 3, and the support platform 4 is located between the two fourth positioning surfaces 31. At the same time, the number of third positioning parts 3 is also configured to be two, and the two third positioning parts 3 are also located on both sides of the support surface 41.

[0033] It is easy to understand that, in order to facilitate the installation of housing A3 into the linear motor assembly equipment, the distance between the two opposing third positioning surfaces 21 is configured to be slightly larger than the distance between the outer side walls of opposite sides of housing A3. In this configuration, if welding is performed on both ends of housing A3, one side needs to be clamped using the third positioning part 3 first. After welding is completed, the third positioning part 3 is released. Then, the third positioning part 3 on the other side is used for clamping. This avoids the housing A3 being stretched in the X direction and deformed due to the simultaneous use of two third positioning parts 3.

[0034] In some implementations, such as Figure 7 As shown, the fourth positioning surface 31 is at least partially offset from the third positioning surface 21.

[0035] Preferably, the fourth positioning surface 31 is completely offset from the third positioning surface 21 and has a certain distance in the Y direction. After the fourth positioning surface 31 is offset from the third positioning surface 21, the housing A3 position corresponding to the fourth positioning surface 31 is exposed to the side of the linear motor assembly equipment, which facilitates further laser welding.

[0036] In some implementations, such as Figure 6 As shown, the linear motor assembly equipment also includes a spring positioning pin 42, which is located between the support platform 4 and the third positioning surface 21. When the motion unit A1 is located on the support surface 41, the spring positioning pin 42 passes through the bending area of ​​the spring plate A2. During the movement of the motion unit A1, the spring positioning pin 42 can play a predetermined role for the motion unit A1 by cooperating with the spring plate A2. At the same time, when the third positioning part 3 pushes and pulls the spring plate A2, the spring positioning pin 42 can limit the range of motion of the spring plate A2, thereby ensuring that the shape of the spring plate A2 does not change too much after it is connected to the housing A3.

[0037] Figure 8 This is an exploded view of the support platform 4 and its various positioning parts. In the figure, the second positioning part 2 and the spring positioning pin 42 are detachably mounted on the support platform 4. Figure 9 This is a cross-sectional schematic diagram of the support platform 4 and the first positioning part 1. Figure 10 Is Figure 7 Schematic diagram of cross-section at point AA. Figure 11 This is a schematic diagram showing the positional relationship between the linear vibration motor and the linear motor assembly equipment in this embodiment.

[0038] In some implementations, such as Figure 8-11 As shown, the linear motor assembly equipment also includes a base 5 and a first drive unit 6. The base 5 has a first slide rail 51 and two top windows 52 communicating with the first slide rail 51. The support platform 4 is detachably installed between the two top windows 52, and the extension direction of the first slide rail 51 is perpendicular to the support surface 41. The first drive unit 6 includes a first drive body 61, which has two first guide ramps 611. The first drive body 61 is slidably disposed in the first slide rail 51, and the two first guide ramps 611 extend from the two top windows 52 respectively.

[0039] Further reference Figure 8 and Figure 9 As shown, the support platform 4 includes multiple guide prisms 43 arranged horizontally. The first positioning part 1 also includes multiple guide blocks 12 corresponding to the multiple guide prisms 43. The guide blocks 12 have guide holes 121 adapted to the guide prisms 43. The guide blocks 12 are sleeved on the guide prisms 43 through the guide holes 121. At the same time, a clamping piece 11 is provided on the top of one end of the guide block 12, and the other end is slidably abutting against the first guide inclined surface 611. The first positioning part 1 moves horizontally under the drive of the first driving body 61. In this embodiment, the up and down movement of the first driving body 61 can be converted into the horizontal synchronous movement of the multiple clamping pieces 11. Thus, the driving operation of the clamping pieces 11 is simplified.

[0040] Optionally, such as Figure 11As shown, the base 5 in the figure includes a top cover 58, a middle body 59, and a bottom plate 55. The aforementioned top window 52 is located on the top cover 58. A crossbeam 582 for mounting the support platform 4 is also provided between the two top windows 52, as well as a first stop block 581 covering the top window 52 (e.g., ...). Figure 8 (As shown). Refer to... Figure 10 As shown, the first positioning part 1 on the left side of the center line in the figure is in a state of imminent clamping, and the guide block 12 is about to fit against the support platform 4. In contrast, the first positioning part 1' in the right figure is in a state away from the support platform 4, and the height of the first driving body 61 on this side is lower than that of the first driving body 61 on the left side. Therefore, by limiting the upward movement of the first driving body 61 by the first stop block 581, and by the cooperation between the guide block 12 and the support platform 4, the clamping force of the clamping piece 11 on the moving unit A1 can be well controlled, protecting the moving unit A1 from damage.

[0041] Figure 11 The figure shows a specific form of the first slide rail 51 and the top window 52. The outline shown by the dotted line in the figure is the first drive body 61 mentioned above. Through the cooperation of the first drive body 61 with the first slide rail 51 and the two top windows 52, the two first guide ramps 611 can move up and down (direction Z) relative to the support platform 4.

[0042] Meanwhile, to ensure that the clamping piece 11 can move stably horizontally relative to the bearing surface 41 and prevent it from rotating, the guide hole 121 is configured as a non-circular hole, that is, adapted to the guide prism 43, with a hole having multiple planes on its inner wall. This ensures that the guide block 821 can slide relative to the guide prism 43 while preventing it from rotating circumferentially.

[0043] Preferably, refer to Figure 6 As shown, a flange extending horizontally is provided at the tail of the guide block 12. The flange can further ensure the configuration accuracy of the guide block 12 and the first guide inclined surface 611.

[0044] In some implementations, such as Figure 3 and 8 As shown in Figure -11, the base 5 includes a base plate 55, a second slide rail 56, and a first elastic member 57. The base plate 55 is located at the end of the first slide rail 51, and the second slide rail 56 extends horizontally and communicates with the first slide rail 51. One end of the first elastic member 57 abuts against the first driving body 61, and the other end abuts against the base plate 55.

[0045] Figure 12 This is a cross-sectional schematic diagram of the central body 59 and the third positioning part 3. Figure 13 This is a structural diagram of the base plate 55 and the third positioning part 3. Refer to... Figure 12 and Figure 13As shown, the first driving unit 6 further includes a roller 62 and a second driving body 63. The roller 62 is rotatably disposed on the first driving body 61. The second driving body 63 has a second guide ramp 631, which is located on the side of the second driving body 63 near the base plate 55. The second driving body 63 is slidably disposed on the second slide rail 56, and drives the first driving body 61 to move through the cooperation of the second guide ramp 631 and the roller 62.

[0046] In this embodiment, under the action of the first elastic member 57, the first driving body can be pushed up towards the top window 52, ​​thereby driving the first positioning part 1 to move. Conversely, the second driving body 63, through the second guide inclined surface 631, presses down on the roller, causing the first driving body 61 to move towards the bottom of the first slide rail 51, thereby releasing the clamping of the motion unit A1. Thus, the first driving part 6 can convert the horizontal movement of the second driving body 63 into the horizontal movement of the clamping piece 11, thereby achieving locking and unlocking of the motion unit A1.

[0047] Specifically, such as Figure 13 As shown, the second drive body 63 also includes a guide recess facing the roller, and the aforementioned second guide ramp 631 is located on the inner wall of the guide recess. When the clamping piece 11 is in an unclamped state, the roller is located in the guide recess and in contact with the bottom surface of the guide recess. As the clamping piece 11 moves toward the bearing surface 41, the guide recess moves horizontally relative to the roller, so that the second guide ramp 631 presses against the roller.

[0048] Optionally, such as Figure 13 As shown, the middle body 59 also includes two second stop blocks 591, which are detachably mounted at both ends of the second slide rail 56. Each second stop block 591 is provided with a first concave structure 592. The second drive body 63 is a columnar structure, with mating sections at both ends corresponding to the second stop blocks 591. Each mating section is also provided with a corresponding second concave structure 632. The second concave structure 632 extends a predetermined distance from the end face of the columnar structure to the center position. The second concave structure 632 and the first concave structure 592 are slidably engaged with each other. Therefore, the travel stroke of the second drive body 63 can be controlled. Figure 13 As shown, the second driving body 63 in the figure has moved to the extreme position on the left.

[0049] In some implementations, such as Figure 12-13As shown, the linear motor assembly equipment also includes a second elastic element 81, a base 5, and a guide post 82. The base 5 has a third slide rail 53 and a receiving groove 54 that communicates with the third slide rail 53 and extends in the same direction. The third slide rail 53 extends along a first direction (direction X). The guide post 82 is slidably disposed within the third slide rail 53. A guide block 821 protrudes laterally from the guide post 82 and extends into the receiving groove 54. The second elastic element 81 simultaneously abuts against the guide block 821 and the inner wall of the receiving groove 54. The third positioning part 3 includes a connector 32, which includes an upper section 321, a middle section 322, and a lower section 323. A fourth positioning surface 31 is located in the upper section 321, the middle section 322 extends horizontally, and the lower section 323 is connected to one end of the guide post 82. In this embodiment, the guide post 82 is disposed inside the middle body 59 using the connector 32, so that it can be driven below the fourth positioning surface 31.

[0050] Figure 14 This is a schematic diagram showing the positional relationship between the ejector portion 7 and the base 5. In some embodiments, such as... Figure 14 As shown, the linear motor assembly equipment also includes an ejector section 7, comprising two ejector heads 71. Each ejector head 71 has an ejector recess 711, which extends along a first direction and is adjacent to the clamping piece 11 at both ends. In a second direction, the two ejector heads 71 ​​are located on opposite sides of the bearing surface 41. The two ejector heads 71 ​​are operably movable in the height direction of the linear motor assembly equipment, and when the linear motor assembly equipment positions the housing A3, the edge of the housing A3 is engaged with the ejector recess 711.

[0051] Refer to Figure 5 As shown in region III, the top of the ejector head 71 can simultaneously contact the bottom and side surfaces of the housing A3 and the bottom surface of the motion unit A1. This allows the linear vibration motor A to be stably lifted. When the linear vibration motor A is small in size, the removal operation of the linear vibration motor A can be simplified, avoiding scratching the housing A3 with clamping tools.

[0052] Preferably, such as Figure 12 As shown, two channels 612 are formed on the first drive body 61, passing through the first drive body 61 from top to bottom, and corresponding one-to-one with the two top windows 52. Two ejector heads 71 ​​can pass through the two windows into the top windows 52. Therefore, in this embodiment, both the channels 612 and the first slide rail 51 extend along the height direction of the linear motor assembly equipment. This allows the first drive body 61 and the ejector heads 71 ​​to move independently relative to the bearing surface 41, facilitating clamping and ejection operations of the linear vibration motor A, respectively.

[0053] The linear motor assembly equipment in the above embodiments can be operated in the following manner. Figure 15 This is a schematic diagram of the linear motor assembly process. In some implementations, such as... Figure 15 As shown, the assembly method includes the following steps.

[0054] Step S100: Provide a linear motor assembly device. The linear motor assembly device includes a support platform 4, the support platform 4 having a support surface 41 arranged in the horizontal direction, a plurality of first positioning parts 1, each first positioning part 1 including a clamping piece 11, the clamping piece 11 having a first positioning surface 111 and a second positioning surface 112 facing away from each other, the first positioning surface 111 facing the support surface 41, a plurality of second positioning parts 2, each second positioning part 2 having a third positioning surface 21 facing the support surface 41, and a third positioning part 3 having a fourth positioning surface 31 facing away from the support surface 41.

[0055] Step S200: Place the motion unit A1 on the bearing surface 41, wherein spring plates A2 are connected to both ends of the motion unit A1.

[0056] Step S300: Drive the clamping plate 11 to fix the motion unit A1.

[0057] Step S400: Attach the housing to the support platform 4 along the second positioning surface 112 and the third positioning surface 21.

[0058] Step S500: Drive the fourth positioning surface 31 to move towards the third positioning surface 21, and push the end of the spring plate A2 away from the moving unit A1 to fit against the inner wall of the housing A3.

[0059] In this embodiment of the linear motor assembly method, the motion unit A1 is first positioned using the first positioning surface 111 to ensure the positional accuracy of the motion unit A1 in the first direction. Then, the housing A3 is simultaneously positioned using the second positioning surface 112 and the third positioning surface 21, further ensuring the positional accuracy of the housing A3 relative to the bearing surface 41. Thus, on the one hand, the clamping piece 11 is inserted between the motion unit A1 and the housing A3 to create a certain gap between them in the second direction, thereby ensuring that the motion unit A1 can move along the centerline of the housing A3. On the other hand, the third positioning surface 21 and the fourth positioning surface 31, forming the clamping pair, are adjacent to each other, preventing excessive deformation of the housing A3 when one end of the spring piece A2 is attached to the inner wall of the housing A3, thus avoiding impact on the dimensional accuracy of the final product.

[0060] Specifically, there are two third positioning parts 3, and the bearing platform 4 is located between the two fourth positioning surfaces 31.

[0061] Under this premise, the fourth positioning surface 31 on one side of the drive bearing surface 41 moves towards the adjacent third positioning surface 21, pushing the end of the spring plate A2 away from the moving unit A1 to fit against the inner wall of the housing A3. During this process, the housing A3 will move a small distance along with the push of the pad A21 and then fit against the third positioning surface 21 on that side.

[0062] In this state, the contact position between the spring sheet A2 on this side and the housing A3 is welded, and then the fourth positioning surface 31 on this side is released.

[0063] The fourth positioning surface 31 on the other side of the drive bearing surface 41 moves toward the adjacent third positioning surface 21, and the above operation is repeated to weld the housing A3 on the other side. This avoids the housing A3 being stretched in the X direction and deformed due to the simultaneous use of two third positioning parts 3.

[0064] Furthermore, the assembly method also includes driving the two ejector heads 71 ​​to lift the housing A3 together with the motion unit A1 and the spring plate. When the linear vibration motor A is small in size, the removal operation of the linear vibration motor A can be simplified, avoiding scratching the housing A3 with clamping tools. At the same time, it can also improve the automation level of the linear motor assembly equipment.

For those skilled in the art, the present invention can be modified and varied in various ways. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of the present invention should be included within the scope of protection of the present invention.
