Fig. 1 and 2 are schematic views of the motor assembly apparatus in different directions. Fig. 3 is an exploded schematic view of the motor assembly apparatus. As shown in fig. 1 to 3, the motor assembling apparatus in the drawings includes a first positioning portion 1, a second positioning portion 2, a third positioning portion 3, a carrying table 4, a base body 5, a first driving portion 6, and an ejector portion 7. The motor assembly device shown in fig. 1 is in an armed state in which the clamping piece 11, the third positioning surface 21 and the fourth positioning surface 31 protrude upwards from the carrier table 4 and are distributed around the carrier surface 41.

Fig. 4 and 5 illustrate a motor. 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 electric energy into linear motion mechanical energy without an intermediate conversion mechanism. Specifically, the moving unit A1 in the drawing is connected to the housing A3 by spring pieces A2 located on both sides thereof. The moving unit A1 is a vibrator of the linear vibration motor a, and the vibrator linearly reciprocates with respect to the housing A3 under the action of a magnetic field. The linear vibration motor a in fig. 4 is in a state before assembly, the housing A3 has a side wall and a bottom, and the top of the housing A3 is in an open state. The spring piece A2 is located the both ends of the motion direction of motion unit A1, and simultaneously, the tip both sides of spring piece A2 still are provided with backing plate A21, and this backing plate A21 can be convenient for spring piece A2 and casing A3 each other weld. Fig. 5 shows the linear vibration motor a in an assembled state. Fig. 6 shows a state in which the linear vibration motor a is disposed on the bearing surface 41, in which the housing A3 is wrapped around the top side and the peripheral side of the moving unit A1 and the spring piece A2.

Fig. 7 is a schematic diagram illustrating the positional relationship between the bearing surface 41 and each positioning portion. Two directions are shown in the figure, as well as direction X and direction Y. The two directions are perpendicular to each other. Also shown in fig. 1 is a direction Z that is perpendicular to both directions X and Y.

In some embodiments, as shown in fig. 1-3, the linear motor assembly apparatus includes a carrier table 4, a plurality of first positioning portions 1, a plurality of second positioning portions 2, and a third positioning portion 3. The stage 4 has a bearing surface 41 provided in the horizontal direction. The first positioning portion 1 includes a clamping piece 11, and the clamping piece 11 has a first positioning surface 111 and a second positioning surface 112 facing away from each other, the first positioning surface 111 facing the bearing surface 41. The second positioning portion 2 has a third positioning surface 21 facing the bearing surface 41. The third positioning part 3 has a fourth positioning surface 31 facing away from the bearing surface 41.

As shown in fig. 7, a plurality of third positioning surfaces 21 are located on both sides of the bearing surface 41 in the first direction (i.e., the direction X), while the fourth positioning surface 31 is operatively moved relative to an adjacent third positioning surface 21, while the fourth positioning surface 31 and the third positioning surface 21 are engaged to form a sandwiching pair, i.e., two sets of fourth positioning surfaces 31 and third positioning surfaces 21 located at the upper left and lower right positions in the drawing. A plurality of first positioning surfaces 111 are located on either side of the bearing surface 41 in a second direction (i.e., direction Y) and are operable to move relative to the bearing surface 41, wherein the first direction is perpendicular to the second direction. Referring to fig. 4-6, when the plurality of first positioning surfaces 111 and the plurality of second positioning surfaces 112 respectively abut against two sides of the moving unit A1 and an inner side wall of the housing A3, the clamping pair pushes one end of the spring piece A2 to be attached to the inner wall of the housing A3, wherein the other end of the spring piece A2 is in a connection state with the moving unit A1.

Specifically, the second positioning portion 2 includes a first positioning block on which the third positioning surface 21 is formed. The third positioning portion 3 includes a second positioning block, and the fourth positioning surface 31 is formed on the second positioning block. The bearing table 4 is provided with a through hole, and the second positioning block extends from the lower part of the bearing surface 41 to the lateral direction of the bearing surface 41 through the through hole. The first positioning block and the second positioning block of the embodiment are used for transmitting clamping force.

The thick solid line in fig. 6 is the outline of the linear vibration motor a, and the thin solid line is the outline of the linear motor assembly apparatus. The direction indicated by the arrow in the figure is the movement direction of the fourth positioning surface 31 when clamping, and the dashed frame i in the figure is the position of the fourth positioning surface 31 when pushing the spring piece A2 to be attached to the housing A3.

The linear motor assembly apparatus of the present embodiment first positions the moving unit A1 using the first positioning surface 111. To ensure positional accuracy of the moving unit A1 in the first direction. Then, the housing A3 is positioned by both the second positioning surface 112 and the third positioning surface 21, so that the positional accuracy of the housing A3 with respect to the bearing surface 41 can be further ensured. Thereby, on the one hand, the clamping piece 11 is inserted between the moving unit A1 and the housing A3 so as to have a certain gap therebetween 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 positioning surface 21 and the fourth positioning surface 31 forming the clamping pair are positioned adjacently, and when one end of the spring piece A2 is attached to the inner wall of the housing A3, excessive deformation of the housing A3 is avoided, and the dimensional accuracy of the final product is affected.

Preferably, a chamfer is provided at the second positioning portion 2, the chamfer being located at the top of the third positioning surface 21. The chamfer may act as a guide for the housing A3 when the housing A3 is fitted into the linear motor assembly device along the third positioning surface 21 and the second positioning surface 112. Meanwhile, the staggered distance between the fourth positioning surface 31 and the third positioning surface 21 should be controlled within a certain range to avoid overlarge clamping force between the two surfaces, so that the shell A3 deforms.

Specifically, as shown in fig. 7, the holding pieces 11 are arranged 4 in pairs on both sides of the bearing surface 41. The number of the third positioning surfaces 21 is 4, 2 are arranged on one side of the bearing surface 41, and the other two are symmetrically distributed in 180-degree rotation with the center of the bearing surface 41. Meanwhile, the number of the fourth positioning surfaces 31 and the number of the spring positioning pins 42 are 2, and are also symmetrically distributed in 180-degree rotation in the center of the bearing surface 41.

Laser welding is a highly efficient and precise welding method that uses a laser beam of high energy density as a heat source. The connection position between the shell A3 and the spring piece A2 in this embodiment can be fixedly connected by laser welding. Region ii shown in fig. 4 and 5 is the spot of laser welding.

In some embodiments, as shown in fig. 7, the number of third positioning portions 3 is two, and the carrying table 4 is located between the two fourth positioning surfaces 31. Meanwhile, the number of the third positioning portions 3 is correspondingly two, and the two third positioning portions 3 are also positioned at two sides of the bearing surface 41.

It will be readily appreciated that in order to facilitate the loading of the housing A3 into the linear motor assembly apparatus, the distance between the two opposed third positioning surfaces 21 is configured to be slightly greater than the distance of the outer side walls on opposite sides of the housing A3. In this state, if both ends of the case A3 are welded, it is necessary to clamp one side by the third positioning portion 3. After the welding is completed, the third positioning portion 3 is released. And then the other side of the third positioning part 3 is used for clamping. Thereby, the case A3 is stretched in the direction X so as to be deformed by avoiding the simultaneous use of two third positioning portions 3.

In some embodiments, as shown in fig. 7, the fourth locating surface 31 is at least partially offset from the third locating surface 21.

Preferably, the fourth positioning surface 31 is completely offset from the third positioning surface 21 with a certain spacing in the direction Y. After the fourth positioning surface 31 is staggered with the third positioning surface 21, the position of the housing A3 corresponding to the fourth positioning surface 31 is exposed in the lateral direction of the linear motor assembly equipment, so that the linear motor assembly equipment can be further subjected to laser welding.

In some embodiments, as shown in fig. 6, the linear motor assembly apparatus further includes a spring positioning pin 42, where the spring positioning pin 42 is located between the bearing table 4 and the third positioning surface 21, and when the moving unit A1 is located on the bearing surface 41, the spring positioning pin 42 is disposed through the bending region of the spring piece A2. The spring positioning pin 42 can play a predetermined role on the moving unit A1 through cooperation with the spring piece A2 during the movement of the moving unit A1. Meanwhile, when the third positioning part 3 pushes and pulls the spring piece A2, the spring positioning pin 42 can play a role in limiting the movement amplitude of the spring piece A2, so that the situation that the shape is not changed excessively after the spring piece A2 is connected with the shell A3 is ensured.

Fig. 8 is an exploded schematic view of the stage 4 and each positioning portion. The second positioning portion 2 and the spring positioning pin 42 are detachably mounted on the carrying table 4 in the drawing. Fig. 9 is a schematic cross-sectional view of the stage 4 and the first positioning portion 1. Fig. 10 is a schematic cross-sectional view at A-A in fig. 7. Fig. 11 is a schematic diagram of the positional relationship of the linear vibration motor and the linear motor assembling apparatus of the present embodiment.

In some embodiments, as shown in fig. 8-11, the linear motor assembly apparatus further includes a base 5 and a first drive 6. The base body 5 has a first slide 51 and two top windows 52 communicating with the first slide 51, the carrying table 4 is detachably mounted between the two top windows 52 and the extending direction of the first slide 51 is perpendicular to the carrying surface 41. The first driving part 6 includes a first driving body 61, the first driving body 61 has two first guiding inclined planes 611, the first driving body 61 is slidably disposed in the first slideway 51, and the two first guiding inclined planes 611 respectively extend from the two top windows 52.

Still further referring to fig. 8 and 9, the carrying floor 4 includes a plurality of guide prisms 43 arranged in the horizontal direction. The first positioning portion 1 further comprises a plurality of guide blocks 12 corresponding to the guide prisms 43 one by one, the guide blocks 12 are provided with guide holes 121 matched with the guide prisms 43, the guide blocks 12 are sleeved on the guide prisms 43 through the guide holes 121, meanwhile, the top of one end of each guide block 12 is provided with a clamping piece 11, and the other end of each guide block 12 is slidably abutted to the first guide inclined surface 611. The first positioning portion 1 moves in the horizontal direction by the drive of the first driving body 61. The present embodiment can convert the up-and-down movement of the first driving body 61 into the horizontal synchronous movement of the plurality of grip pieces 11. Thereby, the driving operation of the grip piece 11 is simplified.

Optionally, as shown in fig. 11, the base 5 in the drawing includes a top cover 58, a middle body 59, and a bottom plate 55. The top window 52 is located on the top cover 58. A cross member 582 for mounting the loading table 4 and a first stopper 581 (shown in fig. 8) provided to cover the top window 52 are further provided between the two top windows 52. Referring to fig. 10 again, the first positioning portion 1 on the left side of the center line is in the state to be clamped, and the guide block 12 is to be attached to the carrying table 4. In contrast, the first positioning portion 1' in the right figure is located away from the stage 4, and the first driving body 61 on the side is lower in height than the first driving body 61 on the left side. Thus, the first stopper 581 limits the upward movement of the first driving body 61, and the guide block 12 and the carrier 4 cooperate with each other, so that the clamping force of the clamping piece 11 on the moving unit A1 can be well controlled, and the moving unit A1 is protected from damage.

Fig. 11 shows a specific form of the first slide 51 and the top window 52, in which the outline shown by the dash-dot line in the first slide 51 is the first driving body 61, and by matching the first driving body 61 with the first slide 51 and the two top windows 52, the two first guiding inclined surfaces 611 can move up and down (direction Z) relative to the carrying platform 4.

At the same time, in order to ensure that the clamping piece 11 can move stably horizontally relative to the bearing surface 41, rotation thereof is avoided. The guide hole 121 is configured to be a non-circular hole, i.e., a hole having a plurality of planes on the inner wall, which is fitted to the guide prism 43. Thereby, the guide block 8211 is prevented from rotating in the circumferential direction while ensuring sliding movement with respect to the guide prism 43.

Preferably, referring again to fig. 6, a flange extending in the horizontal direction is provided at the rear of the guide block 12, by which the arrangement accuracy of the guide block 12 and the first guide slope 611 can be further ensured.

In some embodiments, as shown in fig. 3 and 8-11, the base 5 includes a base plate 55, a second slide 56, and a first resilient member 57. The bottom plate 55 is located at the end of the first slide 51, and the second slide 56 extends in the horizontal direction and communicates with the first slide 51. One end of the first elastic member 57 abuts against the first driving body 61, and the other end abuts against the bottom plate 55.

Fig. 12 is a schematic sectional view of the intermediate body 59 and the third positioning portion 3. Fig. 13 is a schematic structural view of the bottom plate 55 and the third positioning portion 3. Referring again to fig. 12 and 13, the first driving part 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 slope 631, and the second guide slope 631 is located at a side of the second driving body 63 near the bottom plate 55. The second driving body 63 is slidably disposed on the second slideway 56, and drives the first driving body 61 to move through the cooperation of the second guiding inclined surface 631 and the roller 62.

In this embodiment, under the action of the first elastic member 57, the first driving body can jack up toward the top window 52, so as to drive the first positioning portion 1 to move. In contrast, the second driving body 63 presses down the roller by the second guide slope 631, and the first driving body 61 can be moved toward the bottom of the first slide 51, thereby releasing the grip of the moving unit A1. Thereby, the first driving part 6 can convert the horizontal movement of the second driving body 63 into the horizontal movement of the grip piece 11, thereby achieving locking and unlocking of the movement unit A1.

Specifically, as shown in fig. 13, the second driving body 63 further includes a guide recess facing the roller, and the above-mentioned second guide slope 631 is located on the inner wall of the guide recess. When the clamping piece 11 is in the unclamped state, the roller is positioned in the guide recess and contacts the bottom surface of the guide recess. During the movement of the clamping plate 11 towards the bearing surface 41, the guiding recess will move horizontally relative to the roller, so that the second guiding inclined surface 631 will press against the roller.

Optionally, as shown in fig. 13, the middle body 59 further includes two second stop blocks 591, and the two second stop blocks 591 are detachably mounted at two ends of the second slide way 56. The second stop block 591 is provided with a first female formation 592. The second driving body 63 has a columnar structure, and mating sections corresponding to the second stopper 591 are provided at both ends of the columnar structure. Each mating segment is also correspondingly provided with a second concave structure 632. The second concave structure 632 extends from the end surface of the columnar structure to the middle position by a predetermined distance. The second female feature 632 slidably interengages with the first female feature 592. Thereby, the movement stroke of the second driving body 63 can be controlled. As shown in fig. 13, the second driving body 63 is moved to the left limit position in the drawing.

In some embodiments, as shown in fig. 12-13, the linear motor assembly apparatus further includes a second elastic member 81, a base 5, and a guide post 82. The base body 5 has a third slide 53 and a receiving groove 54 communicating with the third slide 53 and extending in the same direction, and the third slide 53 extends in the first direction (direction X). The guide post 82 is slidably disposed in the third slide way 53, the guide post 82 is laterally provided with a guide block 821 in a protruding manner, the guide block 821 extends into the accommodating groove 54, and the second elastic member 81 is simultaneously abutted against the guide block 821 and the inner wall of the accommodating groove 54. The third positioning portion 3 includes a connecting member 32, the connecting member 32 includes 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 post 82. The present embodiment utilizes the connector 32 to locate the guide post 82 within the central body 59 so that it can be driven under the fourth locating surface 31.

Fig. 14 is a schematic diagram showing the positional relationship between the ejector 7 and the base 5. In some embodiments, as shown in fig. 14, the linear motor assembly apparatus further includes an ejector 7 including two ejector heads 71, the ejector heads 71 having ejector recesses 711, the ejector recesses 711 extending in a first direction and being adjacent to the clamping pieces 11 at both ends, and the two ejector heads 71 being located at both sides of the bearing surface 41, respectively, in a second direction. The two ejector heads 71 are operatively moved in the height direction of the linear motor assembly apparatus, and when the linear motor assembly apparatus positions the housing A3, the edge of the housing A3 is caught in the ejection recess 711.

Referring again to region iii in fig. 5, the top of the ejector head 71 may be in contact with both the bottom and side surfaces of the housing A3 and the bottom surface of the moving unit A1. Thereby stably jacking up the linear vibration motor a. When the linear vibration motor a is small in size, the taking-out operation of the linear vibration motor a can be simplified, and the case A3 is prevented from being scratched by using a clamping tool.

Preferably, as shown in fig. 12, two channels 612 are formed on the first driving body 61, and the two channels 612 penetrate through the first driving body 61 from below and up, and are in one-to-one correspondence with the two top windows 52. The two heads 71 may penetrate the top window 52 through two windows. Thus, the passage 612 and the first slide 51 in the present embodiment both extend in the direction of the height of the linear motor assembly apparatus. Thus, the first driving body 61 and the ejector 71 are allowed to move independently with respect to the bearing surface 41, so that the clamping operation and the ejection operation are performed on the linear vibration motor a, respectively.

The linear motor assembly apparatus of the above-described embodiment may operate in the following manner. Fig. 15 is a schematic view of a linear motor assembly flow, and in some embodiments, as shown in fig. 15, the assembly method includes the following steps.

Step S100: a linear motor assembly apparatus is provided. The linear motor assembly device comprises a bearing table 4, wherein the bearing table 4 is provided with a bearing surface 41 arranged in the horizontal direction, a plurality of first positioning parts 1, each first positioning part 1 comprises a clamping piece 11, each clamping piece 11 is provided with a first positioning surface 111 and a second positioning surface 112 which are away from each other, each first positioning surface 111 faces the bearing surface 41, a plurality of second positioning parts 2, each second positioning part 2 is provided with a third positioning surface 21 facing the bearing surface 41, and each third positioning part 3 is provided with a fourth positioning surface 31 which faces away from the bearing surface 41.

Step S200: the moving unit A1 is placed on the bearing surface 41, wherein spring pieces A2 are connected to two ends of the moving unit A1.

Step S300: the driving nip plate 11 fixes the moving unit A1.

Step S400: the housing is snapped onto the carrier 4 along the second positioning surface 112 and the third positioning surface 21.

Step S500: the fourth positioning surface 31 is driven to move towards the third positioning surface 21, and one end of the spring piece A2 away from the moving unit A1 is pushed to be attached to the inner wall of the shell A3.

In the linear motor assembly method of the present embodiment, the first positioning surface 111 is used to position the moving unit A1. To ensure positional accuracy of the moving unit A1 in the first direction. Then, the housing A3 is positioned by both the second positioning surface 112 and the third positioning surface 21, so that the positional accuracy of the housing A3 with respect to the bearing surface 41 can be further ensured. Thereby, on the one hand, the clamping piece 11 is inserted between the moving unit A1 and the housing A3 so as to have a certain gap therebetween 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 positioning surface 21 and the fourth positioning surface 31 forming the clamping pair are positioned adjacently, and when one end of the spring piece A2 is attached to the inner wall of the housing A3, excessive deformation of the housing A3 is avoided, and the dimensional accuracy of the final product is affected.

Specifically, the number of the third positioning portions 3 is two, and the carrying table 4 is located between the two fourth positioning surfaces 31.

On this occasion, the fourth positioning surface 31 on the side of the driving bearing surface 41 moves in the direction of the adjacent third positioning surface 21, and the end of the spring piece A2 away from the moving unit A1 is pushed to be in contact with the inner wall of the housing A3. In this process, the housing A3 moves a small distance together with the pushing of the pad a21, and then is attached to the third positioning surface 21 on the side.

In this state, the bonding position of the spring piece A2 and the housing A3 on the side is welded, and then the fourth positioning surface 31 on the side is released.

The fourth positioning surface 31 on the other side of the driving bearing surface 41 moves in the direction of the adjacent third positioning surface 21, and the above operation is repeated to weld the case A3 on the other side. Thereby, the case A3 is stretched in the direction X so as to be deformed by avoiding the simultaneous use of two third positioning portions 3.

Further, the assembling method further includes driving the two ejection heads 71 to jack up the housing A3 together with the moving unit A1 and the spring piece. When the linear vibration motor a is small in size, the taking-out operation of the linear vibration motor a can be simplified, and the case A3 is prevented from being scratched by using a clamping tool. At the same time, the automation level of the linear motor assembly device can be improved.

The above description is only of the preferred embodiments of the present utility model and is not intended to limit the present utility model, and various modifications and variations may be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
