[0090] The present application is described in detail below based on examples, but the present application is not limited only to these examples. In the following detailed description of the present application, some specific details are described in detail. The present application can be fully understood without the description of these details by those skilled in the art. In order to avoid confusion of the essence of the present application, well-known methods, processes, procedures, elements and circuits are not described in detail.

[0091] Unless otherwise explicitly defined and limited, the terms "mounting", "connected", "connected", "fixed" and the like should be understood broadly, for example, can be fixed connection, or can be detachable connection, or can be integrated; can be directly connected, or indirectly connected through an intermediate medium, can be the internal communication of two elements or the interaction relationship of two elements, unless otherwise explicitly limited. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0092] For ease of description, spatially relative terms such as "inner", "outer", "below", "lower", "bottom", "top", "upper", and the like, are used herein for describing an element's or feature's relationship to another element or feature within a figure. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if a device is turned over, elements described as "below" or "beneath" other elements or features would then be oriented "above" the other elements or features. Thus, the example term "below" can encompass both an orientation of above and below. The device can be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein should be interpreted accordingly.

[0093] Figure 1 and Figure 2 are structural schematic diagrams of different directions of the motor assembly device. Figure 3 is an exploded schematic diagram of the motor assembly device. As shown in Figures 1-3 the motor assembly device in the figure includes a first positioning part 1, a second positioning part 2, a third positioning part 3, a bearing table 4, a base body 5, a first driving part 6 and an ejection part 7.Figure 1 The 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.

[0094] 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.

[0095] 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.

[0096] In some implementations, such as Figures 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.

[0097] like Figure 7As shown, in the first direction (i.e. direction X) a plurality of third locating surfaces 21 are located on both sides of the bearing surface 41, while a fourth locating surface 31 is operable to move relative to an adjacent third locating surface 21, and the fourth locating surface 31 and the third locating surface 21 form a clamping pair, i.e. the two groups of fourth locating surfaces 31 and third locating surfaces 21 located at the upper left and lower right positions in the figure. In the second direction (i.e. direction Y) a plurality of first locating surfaces 111 are located on both sides of the bearing surface 41 and are operable to move relative to the bearing surface 41, wherein the first direction is perpendicular to the second direction. Referring again to Figures 4-6 As shown, when the plurality of first locating surfaces 111 and the plurality of second locating surfaces 112 abut the two sides of the moving unit A1 and the inner side wall of the housing A3, the clamping pair pushes one end of the spring piece A2 to abut the inner wall of the housing A3, and the other end of the spring piece A2 is in a connected state with the moving unit A1.

[0098] Specifically, the second locating portion 2 includes a first locating block, and the third locating surface 21 is formed on the first locating block. The third locating portion 3 includes a second locating block, and the fourth locating surface 31 is formed on the second locating block. The bearing table 4 is provided with a through hole, and the second locating block extends from below the bearing surface 41 to the side of the bearing surface 41 through the through hole. The first locating block and the second locating block of the embodiment are used to transmit clamping force.

[0099] Figure 6 The thick solid line is the contour of the linear vibration motor A, and the thin solid line is the contour of the linear motor assembly device. The arrow direction in the figure is the movement direction of the fourth locating surface 31 when clamping, and the dashed box I in the figure is the position of the fourth locating surface 31 when pushing the spring piece A2 to abut the housing A3.

[0100] The linear motor assembly device of the embodiment first uses the first locating surface 111 to position the moving unit A1. To ensure the position accuracy of the moving unit A1 in the first direction. Then, simultaneously use the second locating surface 112 and the third locating surface 21 to position the housing A3, which can further ensure the position accuracy of the housing A3 relative to the bearing surface 41. Thus, on the one hand, the clamping piece 11 is arranged between the moving unit A1 and the housing A3, so that the two have a certain gap in the second direction, thereby ensuring that the moving unit A1 can move along the center line of the housing A3. On the other hand, the third locating surface 21 and the fourth locating surface 31 forming the clamping pair are located adjacent to each other, and when one end of the spring piece A2 abuts the inner wall of the housing A3, the deformation of the housing A3 is avoided, which affects the size accuracy of the final product.

[0101] Preferably, the second positioning part 2 is provided with a chamfer, which is located at the top of the third positioning surface 21. When the shell A3 is loaded into the linear motor assembly device along the third positioning surface 21 and the second positioning surface 112, the chamfer can guide the shell 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 the two, causing the shell A3 to deform.

[0102] Specifically, as shown in Figure 7 , the clamping pieces 11 are configured as four, and are arranged in pairs on both sides of the bearing surface 41. The number of third positioning surfaces 21 is four, two of which are arranged on one side of the bearing surface 41, and the other two are distributed in 180-degree rotational symmetry with the center of the bearing surface 41. At the same time, the number of fourth positioning surfaces 31 and spring positioning pins 42 is two, which are also distributed in 180-degree rotational symmetry with the center of the bearing surface 41.

[0103] Laser welding is a high-efficiency and precise welding method using a high-energy density laser beam as a heat source. Laser welding can be used to fixedly connect the connection position of the shell A3 and the spring piece A2 in the embodiment. Figure 4 and 5 The area II shown in

[0104] In some embodiments, as shown in Figure 7 , the number of third positioning parts 3 is two, and the bearing table 4 is located between the two fourth positioning surfaces 31. At the same time, the number of third positioning parts 3 is also configured as two, and the two third positioning parts 3 are also located on both sides of the bearing surface 41.

[0105] It is easy to understand that in order to facilitate the loading of the shell A3 into the linear motor assembly device, the distance between the two opposite third positioning surfaces 21 is configured to be slightly larger than the distance of the outer side wall of the opposite side of the shell A3. In this state, if the two ends of the shell A3 are welded, the third positioning part 3 needs to be used to clamp one side first. After welding is completed, the third positioning part 3 is released. Then use the third positioning part 3 on the other side to clamp. In this way, the use of two third positioning parts 3 at the same time is avoided, which causes the shell A3 to be stretched in the direction X, causing it to deform.

[0106] In some embodiments, as shown in Figure 7 , the fourth positioning surface 31 and the third positioning surface 21 are at least partially staggered.

[0107] Preferably, the fourth positioning surface 31 and the third positioning surface 21 are completely staggered and have a certain interval in the direction Y. After the fourth positioning surface 31 and the third positioning surface 21 are staggered, the position of the shell A3 corresponding to the fourth positioning surface 31 is exposed to the side of the linear motor assembly device, which facilitates further laser welding.

[0108] In some embodiments, as shown in Figure 6 The linear motor assembly device further comprises a spring positioning pin 42, which is located between the bearing table 4 and the third positioning surface 21, and penetrates the bending area of the spring sheet A2 when the moving unit A1 is located on the bearing surface 41. The spring positioning pin 42 can play a predetermined role on the moving unit A1 during the movement of the moving unit A1 by cooperating with the spring sheet A2. Meanwhile, when the third positioning part 3 pushes and pulls the spring sheet A2, the spring positioning pin 42 can limit the movement amplitude of the spring sheet A2, thereby ensuring that the spring sheet A2 does not change too much in shape after being connected to the shell A3.

[0109] Figure 8 is an exploded view of the bearing table 4 and each positioning part. The second positioning part 2 and the spring positioning pin 42 are detachably mounted on the bearing table 4. Figure 9 is a cross-sectional view of the bearing table 4 and the first positioning part 1. Figure 10 is a cross-sectional view of the bearing table 4 and the first positioning part 1. Figure 7 is a cross-sectional view of the bearing table 4 and the first positioning part 1. Figure 11 is a schematic view of the position relationship between the linear vibration motor and the linear motor assembly device of the present embodiment.

[0110] In some embodiments, as shown in Figures 8-11 The linear motor assembly device further comprises a base body 5 and a first driving part 6. The base body 5 has a first sliding channel 51 and two top windows 52 in communication with the first sliding channel 51, and the bearing table 4 is detachably mounted between the two top windows 52 and the extension direction of the first sliding channel 51 is perpendicular to the bearing surface 41. The first driving part 6 comprises a first driving body 61 having two first guide inclined surfaces 611, and the first driving body 61 is slidably arranged in the first sliding channel 51, and the two first guide inclined surfaces 611 respectively correspondingly extend from the two top windows 52.

[0111] Further referring to Figure 8 and Figure 9 The bearing table 4 comprises a plurality of guide prisms 43 arranged in the horizontal direction. The first positioning part 1 further comprises a plurality of guide blocks 12 corresponding to the plurality of guide prisms 43, and the guide block 12 has a guide hole 121 adapted to the guide prism 43, and the guide block 12 is sleeved on the guide prism 43 through the guide hole 121, and the top of one end of the guide block 12 is provided with a clamping sheet 11, and the other end is slidably abutted with the first guide inclined surface 611. The first positioning part 1 moves in the horizontal direction under the driving of the first driving body 61. The present embodiment can convert the up-down movement of the first driving body 61 into the horizontal synchronous movement of the plurality of clamping sheets 11. Thus, the driving operation of the clamping sheet 11 is simplified.

[0112] Optionally, as shown in 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 clamping state, 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.

[0113] 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.

[0114] 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.

[0115] 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.

[0116] 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.

[0117] 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 part 6 further comprises a roller 62 and a second driving body 63. The roller 62 is rotatably arranged on the first driving body 61. The second driving body 63 has a second guiding slope 631 on the side of the second driving body 63 close to the bottom plate 55. The second driving body 63 is slidably arranged on the second slide 56 and drives the first driving body 61 to move through the cooperation of the second guiding slope 631 and the roller 62.

[0118] Under the action of the first elastic member 57, the first driving body can be lifted towards the top window 52 to drive the first positioning part 1 to move. On the contrary, the second driving body 63 can drive the roller to move downwards through the second guiding slope 631, so that the first driving body 61 moves towards the bottom of the first slide 51 to release the clamping of the moving 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 to realize the locking and unlocking of the moving unit A1.

[0119] Specifically, as shown in Figure 13 The second driving body 63 further comprises a guiding recess, which faces the roller, and the second guiding slope 631 is located on the inner wall of the guiding recess. When the clamping piece 11 is in the unclamped state, the roller is located in the guiding recess and in contact with the bottom surface of the guiding recess. During the movement of the clamping piece 11 towards the bearing surface 41, the guiding recess moves horizontally relative to the roller to make the second guiding slope 631 abut against the roller.

[0120] Optionally, as shown in Figure 13 The middle body 59 further comprises two second stop blocks 591, which are detachably arranged at the two ends of the second slide 56. The second stop block 591 is provided with a first recess structure 592. The second driving body 63 is a columnar structure, and the two ends of the columnar structure are corresponding matching segments with the second stop block 591. Each matching segment is also provided with a second recess structure 632. The second recess structure 632 extends from the end surface of the columnar structure to a middle position by a predetermined distance. The second recess structure 632 and the first recess structure 592 are slidably engaged with each other. Thus, the movement stroke of the second driving body 63 can be controlled. As shown in Figure 13 The second driving body 63 in the figure moves to the limit position on the left side.

[0121] In some embodiments, as shown in Figures 12-13As shown, the linear motor assembly device further comprises a second elastic member 81, a base body 5 and a guide column 82. The base body 5 has a third sliding channel 53 extending along the first direction (direction X) and a receiving groove 54 communicating with the third sliding channel 53 and extending in the same direction. The guide column 82 is slidably arranged in the third sliding channel 53 and laterally protrudes a guide block 821 extending into the receiving groove 54, and the second elastic member 81 abuts against the guide block 821 and the inner wall of the receiving groove 54. The third positioning part 3 comprises a connecting member 32 comprising an upper section 321, a middle section 322 and a lower section 323, the fourth positioning surface 31 is located on the upper section 321, the middle section 322 extends along the horizontal direction, and the lower section 323 is connected with one end of the guide column 82. In this embodiment, the guide column 82 is arranged inside the middle body 59 by the connecting member 32, so that the fourth positioning surface 31 can be driven below it.

[0122] Figure 14 is a schematic view of the positional relationship between the ejection part 7 and the base body 5. In some embodiments, as shown, Figure 14 the linear motor assembly device further comprises the ejection part 7 comprising two ejection heads 71, each of which has an ejection recess 711 extending along the first direction and adjacent to the clamping piece 11 at both ends, and in the second direction, the two ejection heads 71 are respectively located on both sides of the bearing surface 41. The two ejection heads 71 are operable to move in the height direction of the linear motor assembly device, and when the positioning housing A3 of the linear motor assembly device is positioned, the edges of the housing A3 are clamped in the ejection recess 711.

[0123] Referring again to the area III shown in Figure 5 , the top of the ejection head 71 can simultaneously contact the bottom surface and side surface of the housing A3 and the bottom surface of the movement unit A1. Thus, the linear vibration motor A is stably lifted. When the volume of the linear vibration motor A is small, the taking-out operation of the linear vibration motor A can be simplified, and the housing A3 is prevented from being scratched by using clamping tools.

[0124] Preferably, as shown in Figure 12 , two passages 612 are formed on the first driving body 61, and the two passages 612 extend through the first driving body 61 and correspond to the two top windows 52 respectively. The two ejection heads 71 can pass through the two windows into the top window 52. Thus, the passage 612 and the first sliding channel 51 in this embodiment both extend along the height direction of the linear motor assembly device. Thus, the first driving body 61 and the ejection head 71 can move independently relative to the bearing surface 41, so as to respectively perform clamping operation and ejection operation on the linear vibration motor A.

[0125] The linear motor assembly device in the above embodiments can be operated in the following manner. Figure 15 is a schematic view of the linear motor assembly process. In some embodiments, as shown inFigure 15 The assembling method comprises the following steps.

[0126] Step S100: providing a linear motor assembling device. The linear motor assembling device comprises a bearing table 4 with a bearing surface 41 arranged in horizontal direction, a plurality of first positioning parts 1 comprising clamping pieces 11 with first positioning surface 111 and second positioning surface 112 facing away from each other, the first positioning surface 111 facing the bearing surface 41, a plurality of second positioning parts 2 with third positioning surface 21 facing the bearing surface 41, and a third positioning part 3 with fourth positioning surface 31 facing away from the bearing surface 41.

[0127] Step S200: placing the moving unit A1 on the bearing surface 41, wherein the moving unit A1 is connected with spring pieces A2 at both ends.

[0128] Step S300: driving the clamping pieces 11 to fix the moving unit A1.

[0129] Step S400: buckling the shell along the second positioning surface 112 and the third positioning surface 21 on the bearing table 4.

[0130] Step S500: driving the fourth positioning surface 31 to move towards the third positioning surface 21, and pushing the end of the spring piece A2 away from the moving unit A1 to abut against the inner wall of the shell A3.

[0131] The linear motor assembling method of the embodiment first positions the moving unit A1 by the first positioning surface 111, so as to ensure the position accuracy of the moving unit A1 in the first direction. Then, the shell A3 is positioned by the second positioning surface 112 and the third positioning surface 21, which further ensures the position accuracy of the shell A3 relative to the bearing surface 41. In this way, on the one hand, the clamping pieces 11 are arranged between the moving unit A1 and the shell A3, so as to ensure a certain gap between the moving unit A1 and the shell A3 in the second direction, thereby ensuring that the moving unit A1 can move along the center line of the shell A3. On the other hand, the third positioning surface 21 and the fourth positioning surface 31 of the clamping pair are located adjacent to each other, so as to avoid excessive deformation of the shell A3 when the end of the spring piece A2 abuts against the inner wall of the shell A3, thereby affecting the dimensional accuracy of the final product.

[0132] Specifically, the number of the third positioning part 3 is two, and the bearing table 4 is located between the two fourth positioning surfaces 31.

[0133] Under the above premise, the fourth positioning surface 31 on the side of the bearing surface 41 is driven to move towards the adjacent third positioning surface 21, and the end of the spring piece A2 away from the moving unit A1 is pushed to abut against the inner wall of the shell A3. During the process, the shell A3 will move a small distance together with the pad A21 and then abut against the third positioning surface 21 on the side.

[0134] In this state, the spring sheet A2 on this side is welded to the abutting position of the housing A3, and then the fourth positioning surface 31 on this side is released.

[0135] The fourth positioning surface 31 on the other side of the driving bearing surface 41 is moved to the direction of the adjacent third positioning surface 21, and the above operation is repeated to weld the housing A3 on the other side. Thus, the simultaneous use of the two third positioning surfaces 3 to stretch the housing A3 in the direction X is avoided, so that the housing A3 is deformed.

[0136] Further, the assembly method further comprises driving the two ejector heads 71 to lift the housing A3 together with the movement unit A1 and the spring sheet. When the linear vibration motor A is small in volume, the taking-out operation of the linear vibration motor A can be simplified, and the housing A3 is prevented from being scratched by using a clamping tool. At the same time, the automation level of the linear motor assembly equipment can be improved.

[0137] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the protection scope of the present application.
