[0076] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0077] See also Figure 1 and Figure 2 The present application provides a positioning device 100, which includes a bearing assembly 10, a positioning assembly 20, a pushing assembly 30 and a pressing assembly 40, and is used to position a first component 300 and a second component 400 to a preset position of a workpiece 200, so that an external laser welding device can weld the first component 300 and the second component 400 to the preset position of the workpiece 200. Please refer to Figure 2 For example, the first component 300 may be a mounting plate with threaded holes, the second component 400 may be a mobile phone support plate, and the workpiece 200 may be a mobile phone middle frame.

[0078] It can be understood that, for the convenience of explaining the embodiments of the present application, Figure 1 A three-dimensional coordinate system is established in the first direction. Figure 1 The X-axis direction is shown, and the second direction is Figure 1 The Z-axis direction is shown, and the third direction is Figure 1 The Y-axis direction is shown.

[0079] See also Figure 1 and Figure 3 , the bearing assembly 10 is used to bear the workpiece 200. Figure 3 , Figure 4 and Figure 5 The positioning assembly 20 includes a first positioning member 21, a second positioning member 22 and a first elastic member 23. The first positioning member 21 is slidably disposed on the bearing assembly 10 along the first direction and is used to position the first element 300. The second positioning member 22 is disposed on the bearing assembly 10 and is used to position the second element 400. The first element 300, the second element 400 and the workpiece 200 are stacked in sequence, and the first element 300 and the second element 400 are both in contact with the workpiece 200. The elastic force direction of the first elastic member 23 is parallel to the first direction, and the two ends of the first elastic member 23 elastically abut the first positioning member 21 and the bearing assembly 10, respectively. Please refer to Figure 3 and Figure 6 The pushing component 30 includes a first pushing member 31, a second pushing member 32 and a rotating member 33. The first pushing member 31 and the second pushing member 32 are sequentially arranged from bottom to top along a second direction perpendicular to the first direction and are both slidably connected to the supporting component 10. The first pushing member 31 and the second pushing member 32 are both located on the side of the first positioning member 21 away from the first elastic member 23. The rotating member 33 is rotatably connected to the supporting component 10. The rotating member 33 is used to rotate along a preset direction and push the first pushing member 31 to move along the first direction, so that the first positioning member 21 compresses the first elastic member 23 to the supporting component 10. The rotating member 33 is also used to rotate along a direction opposite to the preset direction and push the second pushing member 32 to move along the first direction, so that the second pushing member 32 positions the workpiece 200 to the supporting component 10 along the first direction. Please refer to Figure 1 and Figure 7 The clamping assembly 40 includes a clamping member 41 and a light-transmitting member 42. The clamping member 41 is detachably connected to the bearing assembly 10, and the clamping member 41 is provided with a light-transmitting groove 411. The light-transmitting groove 411 penetrates the clamping member 41 along the second direction and corresponds to the first positioning member 21 and the second positioning member 22. The clamping member 41 is used to clamp the workpiece 200 to the bearing assembly 10. The light-transmitting member 42 is connected to the clamping member 41 and covers the light-transmitting groove 411. The light-transmitting member 42 is used to transmit the laser beam emitted by the external laser device so that the laser beam is irradiated to the abutting area between the first element 300, the second element 400 and the workpiece 200. Exemplarily, the first elastic member 23 can be a spring, the number of the clamping assembly 40 is two groups, and the two groups of clamping assemblies 40 are used to clamp the opposite ends of the same side of the workpiece 200. The light-transmitting member 42 can be a light-transmitting block, a light-transmitting plate or a similar light-transmitting body with a high light-transmitting lens. It can be understood that the rotating member 33 rotates in a preset direction means that the rotating member 33 rotates in a clockwise direction or a counterclockwise direction.

[0080] In the above-mentioned positioning device 100, the first element 300 and the second element 400 covered on the first element 300 are positioned respectively by the first positioning member 21 and the second positioning member 22, and the workpiece 200 is pressed onto the supporting member 10 by the clamping assembly 40, so that the first element 300, the second element 400 and the workpiece 200 are stacked in sequence to accurately position the first element 300 and the second element 400 to the preset position of the workpiece 200, so that the laser beam emitted by the external laser device is transmitted through the light-transmitting member 42 and the light-transmitting groove 411 to the abutment area between the first element 300 and the second element 400 and the workpiece 200, so that the first element 300 and the second element 400 are quickly welded to the preset position of the workpiece 200, so as to complete the welding operation of the stacked first element 300, the second element 400 and the workpiece 200 at one time, simplify the positioning process and the welding process, and thus improve the welding efficiency.

[0081] See also Figure 4 and Figure 5 In some embodiments, the first positioning member 21 includes a sliding body 211, a positioning body 212 and a first elastic body 213. The sliding body 211 is slidably disposed on the bearing assembly 10 along the first direction and abuts against the first elastic member 23, and an end of the sliding body 211 away from the bearing assembly 10 is provided with a receiving groove 2111 for receiving the first element 300. The positioning body 212 is movably disposed on the sliding body 211 along the second direction and extends into the receiving groove 2111, and the positioning body 212 is used to position the first element 300 in the receiving groove 2111. The elastic force direction of the first elastic body 213 is parallel to the second direction, and the two ends of the first elastic body 213 elastically abut the positioning body 212 and the bearing assembly 10 respectively. Exemplarily, the first elastic body 213 can be a spring.

[0082] In this way, when the rotating member 33 rotates along the preset direction and pushes the first pushing member 31 to move along the first direction, the sliding body 211 can form a sufficiently large distance between the sliding body 211 and the second pushing member 32 under the push of the first pushing member 31, so that the receiving groove 2111 of the sliding body 211 can receive the first element 300. In addition, in this embodiment, it is necessary to simultaneously position multiple first elements 300 to the second element 400, and each first element 300 and the second element 400 have different positioning height requirements in the second direction. Therefore, in this embodiment, multiple first positioning members 21 are provided, and multiple first positioning members 21 are arranged at intervals on the bearing assembly 10. When the second positioning member 22 positions the second element 400 covered on the multiple first elements 300, the second element 400 moves in the direction close to the bearing assembly 10 through the multiple first elements 300 pressing the corresponding positioning body 212 and compressing the corresponding first elastic body 213, so that the second element 400 and the multiple first elements 300 form a floating contact, thereby positioning the multiple first elements 300 at different heights of the second element 400, thereby improving the positioning accuracy. It can be understood that the above-mentioned multiple refers to two or more.

[0083] See also Figure 3 and Figure 4 In some embodiments, the positioning assembly 20 further includes a pressing member 24 , which is disposed on one side of the first positioning member 21 and is rotatably connected to the supporting assembly 10 , and is used to press the second element 400 onto the first element 300 .

[0084] In this way, by setting the pressing piece 24 to be rotatably connected with the supporting assembly 10, the pressing piece 24 can press the second element 400 to the first element 300, so that the first element 300 is accurately positioned to the fixed position of the second element 400, avoiding shaking of the first element 300 and the second element 400 during the welding process, thereby improving the positioning accuracy.

[0085] See also Figure 5 and Figure 6 In some embodiments, the first pusher 31 and the second pusher 32 each include a pusher 311 and a second elastic body 312. The pusher 311 is movably disposed in the bearing assembly 10 along the first direction. The elastic force direction of the second elastic body 312 is parallel to the first direction, and the two ends of the second elastic body 312 elastically resist the pusher 311 and the bearing assembly 10 respectively. Exemplarily, the second elastic body 312 can be a spring.

[0086] In this way, by setting the specific structure of the first pushing member 31 and the second pushing member 32 mentioned above, when the pushing body 311 performs a pushing operation driven by the rotating member 33, the second elastic body 312 is compressed to the supporting component 10. When the pushing body 311 completes the pushing operation, the compressed second elastic body 312 provides elastic force and drives the pushing body 311 to return to its initial position, so that the first pushing member 31 and the second pushing member 32 can repeat the pushing operation.

[0087] See also Figure 6 In some embodiments, the rotating member 33 includes a rotating body 331, a first protrusion 332, a second protrusion 333 and a handle 334. The rotating body 331 is rotatably connected to the bearing assembly 10, and the first protrusion 332 and the second protrusion 333 are staggered along the second direction on the side wall of the rotating body 331 and correspond to the first pusher 31 and the second pusher 32 respectively. The handle 334 is connected to the rotating body 331, and the handle 334 is used to drive the rotating body 331 to rotate under the action of an external force, so that the first protrusion 332 pushes the first pusher 31, or the second protrusion 333 pushes the second pusher 32.

[0088] In this way, the rotating body 331 rotates in different directions driven by the handle 334, so that the first protrusion 332 and the second protrusion 333 can respectively push the corresponding first pushing member 31 and the second pushing member 32 to move along the first direction, avoiding the positioning device 100 from being equipped with too many driving components, simplifying the mechanical structure of the rotating member 33, and thus making the layout of the positioning device 100 reasonable.

[0089] See also Figure 3 In some embodiments, the positioning device 100 further includes a clamping assembly 50, and the clamping assembly 50 includes a fixed member 51, a clamping member 52, and a movable member 53. The fixed member 51 and the second pusher 32 are staggered along the third direction and arranged on the bearing assembly 10. The clamping member 52 is arranged opposite to the fixed member 51 along the third direction and is slidably connected to the bearing assembly 10, and the clamping member 52 is used to clamp and position the workpiece 200 to the fixed member 51 along the third direction. The movable member 53 is slidably arranged on the bearing assembly 10 along the first direction and abuts against the inclined surface of the clamping member 52. The movable member 53 is used to move along the first direction under the action of an external force and push the clamping member 52 along the third direction, so that the clamping member 52 moves close to the fixed member 51 along the third direction.

[0090] In this way, the movable member 53 moves along the first direction under the action of external force, and drives the clamping member 52 to move along the third direction close to the fixed member 51, so that the clamping member 52 and the fixed member 51 clamp and position the workpiece 200 along the third direction, thereby realizing mechanized positioning of the workpiece 200 and improving positioning efficiency.

[0091] In some embodiments, the movable member 53 includes a movable body 531, a third elastic body 532, a cam body 533 and a handle 534. The movable body 531 is slidably disposed on the bearing assembly 10 along the first direction and abuts against the clamping member 52 at an inclined surface, and the movable body 531 is provided with a through groove 5311 along the second direction, and the through groove 5311 includes a first groove wall 5312 and a second groove wall 5313 that are oppositely disposed along the first direction. The elastic force direction of the third elastic body 532 is parallel to the first direction, and the two ends of the third elastic body 532 elastically abut the movable body 531 and the bearing assembly 10 respectively. The cam body 533 is received in the through slot 5311 and is rotatably connected to the bearing assembly 10. The handle 534 is connected to the cam body 533. The handle 534 is used to drive the cam body 533 to abut against the first slot wall 5312 under the action of an external force to drive the movable body 531 to move in a direction away from the third elastic body 532, or to abut against the second slot wall 5313 to drive the movable body 531 to move in a direction close to the third elastic body 532. Exemplarily, the third elastic body 532 may be a spring, and the cam body 533 may be an eccentric cam.

[0092] In this way, when the cam body 533 rotates in the through groove 5311 and abuts against the first groove wall 5312, the cam body 533 can drive the movable body 531 to move away from the third elastic body 532 and stretch the third elastic body 532, so that the movable body 531 can stably push the clamping member 52 to move along the second direction, thereby improving the positioning stability; when the cam body 533 rotates in the through groove 5311 and abuts against the second groove wall 5313, the stretched third elastic body 532 can provide elastic force and drive the movable body 531 to move in the direction close to the third elastic body 532, so that the movable body 531 stops pushing the clamping member 52, so that the clamping member 52 loosens the clamped workpiece 200, which is convenient for the positioning device 100 to repeatedly clamp and position the workpiece 200.

[0093] In some embodiments, the bearing assembly 10 includes a bearing member 11, a cover member 12 and a pressing member 13. The bearing member 11 is provided with a mounting groove 111 and a limiting groove 112. The mounting groove 111 is provided in the middle of the bearing member 11 and receives the movable member 53 and part of the clamping member 52. The limiting groove 112 is provided on the same side of the bearing member 11 around the mounting groove 111. The limiting groove 112 is used to receive and limit the workpiece 200. The cover member 12 covers the mounting groove 111 and is connected to the bearing member 11. The pressing member 13 is provided on one side of the bearing member 11 and is rotatably connected to the bearing member 11. The pressing member 13 is used to press the clamping member 41 to the bearing member 11 so that the bearing member 11 and the clamping member 41 are detachably connected. Among them, the positioning assembly 20 and the pushing assembly 30 are both provided on the bearing member 11.

[0094] In this way, by accommodating the movable member 53 and part of the clamping member 52 in the installation groove 111, the layout of the carrier assembly 10 and the clamping member 50 can be made reasonable, and by covering the installation groove 111 with the cover member 12, the cover member 12 can cover the installation groove 111 to prevent external factors from interfering with the linkage operation between the movable member 53 and the clamping member 52. In addition, by pressing the pressing member 41 against the carrier 11 with the pressing member 13, the pressing member 41 can stably press the workpiece 200 against the carrier 11 under the pressure of the pressing member 13, thereby improving the pressing stability of the pressing member 40, and at the same time realizing the detachable connection between the pressing member 40 and the carrier assembly 10, so as to facilitate the taking and placing of the workpiece 200.

[0095] See also Figure 1 and Figure 7 In some embodiments, the pressing member 41 includes a pressing body 412, a plurality of guide bodies 413, a plurality of fourth elastic bodies 414, and a supporting body 415. The pressing body 412 is movably placed on the carrier 11, and is used to press the workpiece 200 to the carrier 11. The plurality of guide bodies 413 are arranged at intervals on the pressing body 412 and are connected to a side of the pressing body 412 away from the carrier 11. The plurality of fourth elastic bodies 414 and the plurality of guide bodies 413 are arranged alternately and at intervals on the pressing body 412. The support body 415 is connected to the light-transmitting member 42 and abuts against the two ends of the plurality of fourth elastic bodies 414 with the pressing body 412 respectively. One end of the guide body 413 away from the pressing body 412 is movably arranged on the support body 415. The light-transmitting groove 411 runs through both sides of the support body 415. The support body 415 is used to compress the plurality of fourth elastic bodies 414 to the pressing body 412 under the pressure of the pressing member 13, so that the pressing body 412 is detachably connected to the carrier 11, and the pressing body 412 flexibly presses the workpiece 200 to the carrier 11. Exemplarily, the fourth elastic body 414 can be a spring.

[0096] Thus, when the clamping assembly 40 performs a clamping operation, the support body 415 compresses the plurality of fourth elastic bodies 414 to the clamping body 412 under the pressure of the pressing member 13, so that the clamping body 412 flexibly presses the workpiece 200 to the carrier 11, thereby preventing the workpiece 200 from being damaged by the large clamping force of the clamping body 412, thereby improving the clamping stability. In addition, by providing a plurality of guide bodies 413 penetrating the support body 415, the guide bodies 413 can guide the movement direction of the support body 415, so that the support body 415 stably compresses the plurality of fourth elastic bodies 414, thereby improving the clamping stability of the clamping assembly 40.

[0097] In some embodiments, the pressing body 412 includes a pressing portion 4121 and a blowing portion 4122, which are spaced apart along the first direction and are respectively connected to the corresponding guide body 413, and the pressing portion 4121 and the blowing portion 4122 are both abutted against the corresponding fourth elastic body 414, and the pressing portion 4121 is used to press the workpiece 200 to the carrier 11, and the blowing portion 4122 is connected to an external air source, and the blowing portion 4122 is used to blow air toward the workpiece 200.

[0098] In this way, by blowing air toward the workpiece 200 through the blowing portion 4122, the heat generated by the workpiece 200 during the welding process can be reduced, and the workpiece 200, the first element 300 and the second element 400 are prevented from being damaged by the continuous high temperature, thereby improving the welding quality of the workpiece 200. In addition, by arranging the pressing portion 4121 and the blowing portion 4122 at intervals along the first direction, a sufficiently large gap can be provided between the pressing portion 4121 and the blowing portion 4122, so that the laser beam can be irradiated to the preset position of the workpiece 200 through the gap formed therebetween.

[0099] The working process of the positioning device 100 described in the above embodiment is roughly as follows:

[0100] First, the rotating member 33 rotates in a preset direction under the action of an external force and pushes the first pushing member 31 to move in the first direction. The sliding body 211 forms a sufficiently large distance with the second pushing member 32 under the push of the first pushing member 31, so that the receiving groove 2111 of the sliding body 211 can receive the first element 300. The positioning body 212 positions the first element 300 in the receiving groove 2111. The second positioning member 22 is positioned on the plurality of first elements 300. The second element 400 moves in a direction close to the bearing assembly 10 by pressing the corresponding positioning body 212 through the plurality of first elements 300 and compressing the corresponding first elastic body 213, so that floating contact is formed between the second element 400 and the plurality of first elements 300, thereby positioning the plurality of first elements 300 at different heights of the second element 400, thereby improving the positioning accuracy.

[0101] Then, the workpiece 200 is placed in the limiting groove 112, and the rotating member 33 rotates in the direction opposite to the preset direction under the action of external force and pushes the second pushing member 32 to move in the first direction, so that the second pushing member 32 positions the workpiece 200 in the first direction. Then, the movable member 53 moves in the first direction under the action of external force, and drives the clamping member 52 to move close to the fixing member 51 in the third direction, so that the clamping member 52 and the fixing member 51 clamp and position the workpiece 200 in the third direction, and the pressing member 41 is placed on the carrier 11 again, and the pressing member 13 presses the pressing member 41 onto the carrier 11, so that the pressing member 41 positions the workpiece 200 to the carrier 11 in the second direction, so as to realize the positioning of the workpiece 200 placed on the second element 400 in the three-dimensional space, so that the first element 300, the second element 400 and the workpiece 200 are stacked in sequence, so that the first element 300 and the second element 400 are quickly positioned to the preset position of the workpiece 200, simplifying the positioning process and thereby improving the welding efficiency.

[0102] Finally, the laser beam emitted by the external laser emitting device passes through the light-transmitting member 42 and the light-transmitting groove 411 in turn to the abutment area between the first element 300, the second element 400 and the workpiece 200, thereby completing the welding operation of the stacked first element 300, the second element 400 and the workpiece 200 at one time, simplifying the welding process and further improving the welding efficiency. Then, the blowing part 4122 blows air toward the workpiece 200 to reduce the heat generated by the workpiece 200 during the welding process, thereby preventing the workpiece 200, the first element 300 and the second element 400 from being damaged by continuous high temperature, and improving the welding quality of the workpiece 200.

[0103] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present application and are not intended to limit it. Although the present application has been described in detail with reference to the preferred embodiments, a person of ordinary skill in the art should understand that the technical solution of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present application.
