[0068] Some embodiments of the present application will be described in detail below with reference to the drawings.

[0069] Please refer to Figure 1 and Figure 2 As shown in, an embodiment of the present application provides a positioning device 100, which includes a bearing assembly 10, a sliding assembly 20 and an adjusting assembly 30. The positioning device 100 is used to position a first workpiece 200 and position a second workpiece 300 at a preset position on the first workpiece 200. Among them, the first workpiece 200 may be a mobile phone frame, and the second workpiece 300 may be a buckle plate.

[0070] Please refer to Figure 1 、 Figure 2 and Figure 3, the bearing component 10 is provided with a placement groove 12 and a bearing position 11 for bearing the first workpiece 200. The sliding component 20 includes a sliding member 21 and an elastic member 22. The sliding member 21 is slidably disposed in the placement groove 12 and is used for positioning the second workpiece 300. One end of the elastic member 22 is connected to the sliding member 21, and the other end of the elastic member 22 abuts against the groove wall of the placement groove 12. The adjusting component 30 includes a fixing member 31, an adjusting member 32, and a rotating member 33. The fixing member 31 is disposed in the placement groove 12. The fixing member 31 is provided with an intersecting receiving groove 311 and a rotating groove 312. The rotating groove 312 penetrates through the fixing member 31 and extends to the bottom wall of the placement groove 12, and the rotating groove 312 communicates with the receiving groove 311. One end of the adjusting member 32 is disposed in the receiving groove 311, and the other end of the adjusting member 32 passes through the side wall of the receiving groove 311 to abut against the sliding member 21. The rotating member 33 is rotatably disposed in the rotating groove 312 and sleeved outside the adjusting member 32, so that rotating the adjusting member 32 can push the sliding member 21 and compress the elastic member 22 against the groove wall of the placement groove 12, and the second workpiece 300 positioned by the sliding member 21 moves relative to the first workpiece 200, so as to move the second workpiece 300 to a preset position of the first workpiece 200. Wherein, the bearing position 11 can be a groove, a protrusion, etc. provided on the bearing component 10 and adapted to the first workpiece 200. Exemplarily, the elastic member 22 can be a spring.

[0071] When the above positioning device 100 is in use, the rotating member 33 drives the adjusting member 32 to rotate, so that the adjusting member 32 pushes the sliding member 21 and compresses the elastic member 22 against the groove of the placement groove 12, so that the second workpiece 300 positioned by the sliding member 21 moves relative to the first workpiece 200. According to the actual sizes and actual structures of the first workpiece 200 and the second workpiece 300, its positioning position is adjusted in real time, so as to accurately position the second workpiece 300 to the preset position of the first workpiece 200, and the adjustment range of the positioning is improved.

[0072] In addition, when the positioning operation is completed, the compressed elastic member 22 provides an elastic force and cooperates with the adjusting member 32 to drive the sliding member 21 to reset to the initial position, facilitating the positioning device 100 to repeat the positioning operation.

[0073] Please refer to Figure 2 and Figure 3 , in some embodiments, the adjusting member 32 includes an adjusting body 321, a connecting body 322, and a locking body 323. The adjusting body 321 is threadedly connected to the side wall of the receiving groove 311 and abuts against the sliding member 21. The connecting body 322 is disposed in the receiving groove 311 and connected to the adjusting body 321, and the rotating member 33 is sleeved outside the connecting body 322. One end of the locking body 323 is connected to the rotating member 33, and the other end of the locking body 323 is connected to the connecting body 322, so that the adjusting member 32 is detachably connected to the rotating member 33. Exemplarily, the locking body 323 can be a screw.

[0074] In this way, by setting the locking body 323 as described above, a detachable connection structure can be formed between the adjusting member 32 and the rotating member 33, facilitating the operator to assemble the rotating member 33 and the adjusting member 32 into the receiving groove 311 of the fixing member 31.

[0075] Please refer to Figure 3 , in some embodiments, the connecting body 322 is provided with a notch platform 3221, the rotating member 33 has a connecting hole 331, the connecting hole 331 has a horizontal plane 3311, the connecting hole 331 is sleeved on the connecting body 322 and the rotating member 33 abuts against the side wall of the notch platform 3221, and the horizontal plane 3311 abuts against the notch platform 3221.

[0076] In this way, by the horizontal plane 3311 abutting against the notch platform 3221, a clamping connection structure can be formed between the connecting body 322 and the rotating member 33, thereby preventing relative rotation between the rotating member 33 and the connecting body 322, enabling the rotating member 33 to stably drive the connecting body 322 to rotate synchronously, and improving the stability of the rotating member 33 driving the locking member to rotate.

[0077] Please continue to refer to Figure 3 , in some embodiments, the carrying assembly 10 includes a stacked base 13 and a carrying block 14. The base 13 is provided with an extension hole 131 communicating with the rotating groove 312, and the extension hole 131 is used to receive a part of the rotating member 33. The carrying position 11 is provided on the upper surface of the carrying block 14, and the carrying block 14 is provided with a placement groove 12.

[0078] In this way, by placing the sliding assembly 20 and the fixing member 31 in the placement groove 12 and receiving a part of the rotating member 33 through the extension hole 131, the positioning device 100 can be reasonably arranged, the mechanical structure of the positioning device 100 can be simplified, and at the same time, the placement groove 12 guides the movement direction of the sliding member 21, improving the positioning accuracy.

[0079] In some embodiments, the carrying block 14 is provided with a limiting groove 141, the limiting groove 141 is opened on the side wall of the placement groove 12 and is used to receive and limit one end of the elastic member 22.

[0080] In this way, by receiving and limiting the elastic member 22 in the limiting groove 141, the elastic member 22 can always be compressed or provide elastic force along the direction from the sliding member 21 to the adjusting member 32, which is beneficial to ensuring the positioning stability.

[0081] In some embodiments, the sliding member 21 includes a sliding block 211 and a positioning body 212. The sliding block 211 is slidably disposed in the placement groove 12 and is connected to the adjusting member 32. The upper surface of the sliding block 211 is flush with the upper surface of the carrying block 14, and the sliding block 211 is connected to the elastic member 22. The positioning body 212 is disposed on the upper surface of the sliding block 211, and the positioning body 212 is used to position the second workpiece 300.

[0082] In this way, by positioning the second workpiece 300 through the positioning body 212, the second workpiece 300 can be maintained in a preset orientation and placement position on the sliding block 211, preventing the second workpiece 300 from shaking, so that the sliding block 211 can stably drive the second workpiece 300 to move to adjust the relative position between the second workpiece 300 and the first workpiece 200.

[0083] Wherein, the number of the positioning bodies 212 can be two. The two positioning bodies 212 are spaced apart on the sliding block 211 along the direction perpendicular to the sliding direction of the sliding block 211. The two positioning bodies 212 are used to position and limit the second workpiece 300, preventing the second workpiece 300 from shaking on the sliding block 211 and improving the positioning stability. Of course, the number of the positioning bodies 212 can also be one or more than two.

[0084] Please continue to refer to Figure 2 and Figure 3 In some embodiments, the fixing member 31 is further provided with a threaded groove 313. The threaded groove 313 is opened on the side of the fixing member 31 away from the sliding block 211 and communicates with the receiving groove 311. The positioning device 100 further includes a stopper 40. The stopper 40 is inserted through the threaded groove 313 along the sliding direction of the sliding block 211 and is threadedly connected to the inner wall of the threaded groove 313. The stopper 40 is used to abut against one end of the adjusting member 32 away from the sliding block 211 to stop the adjusting member 32.

[0085] In this way, by providing the above-mentioned stopper 40, when the adjusting member 32 completes the adjustment operation, the stopper 40 abuts against one end of the adjusting member 32 away from the sliding block 211 to stop the adjusting member 32, preventing the rotating member 33 and the adjusting member 32 from rotating due to external force interference and causing the positioning position of the second workpiece 300 to deviate from the preset position. This is beneficial to improving the positioning stability.

[0086] Please refer to Figure 3 In some embodiments, the stopper 40 includes a stop body 41 and a clamping body 42. The stop body 41 is threadedly connected to the inner wall of the threaded groove 313 and is used to stop the adjusting member 32. The clamping body 42 is connected to one end of the stop body 41 away from the adjusting member 32 and is provided with a clamping groove 421. The clamping groove 421 is located at the end of the clamping body 42 away from the stop body 41. The clamping groove 421 is used to clamp an external workpiece. Exemplarily, the clamping groove 421 can be a straight groove, a cross-shaped groove, etc., and the external workpiece can be a screwdriver.

[0087] In this way, by providing the above-mentioned clamping groove 421 to clamp the external workpiece, the external workpiece can be stably connected to the clamping body 42, and then the external workpiece can stably act on the clamping body 42 and drive the stop body 41 to rotate, realizing that the stop body 41 stably abuts against and stops the adjusting member 32, improving the stopping stability.

[0088] In some embodiments, the rotating member 33 protrudes out of the rotating groove 312, which makes it easy for the operator to act on the rotating member 33, helps the operator drive the rotating member 33 to rotate, and improves the convenience of the operation.

[0089] See also Figure 3 In some embodiments, the rotating member 33 is provided with a plurality of scale lines 332, and the plurality of scale lines 332 are arranged on the side of the rotating member 33 along the circumference of the rotating member 33, so that the operator can adjust the rotation angle of the rotating member 33 based on the scale lines 332, thereby adjusting the movement distance of the sliding block 211 driven by the adjusting member 32, thereby realizing precise adjustment of the positioning position of the second workpiece 300 and improving the positioning accuracy.

[0090] The present application also provides a welding device (not shown), which includes the positioning device 100 of any of the above embodiments and a welding nozzle (not shown), the welding nozzle is used to weld the second workpiece 300 positioned at a preset position of the first workpiece 200, so as to weld the second workpiece 300 to the first workpiece 200. The welding nozzle can be an electric welding nozzle or a laser welding nozzle.

[0091] The working process of the positioning device 100 is roughly as follows:

[0092] First, the first workpiece 200 is placed on the carrying position 11 for positioning, and the second workpiece 300 is placed on the positioning body 212 for positioning;

[0093] Next, based on the actual size and structure of the first workpiece 200 and the second workpiece 300, the rotating member 33 is rotated in a clockwise or counterclockwise direction, so that the adjusting member 32 pushes the second workpiece 300 carried by the sliding block 211 to move relative to the first workpiece 200, and compresses the elastic member 22 to the bottom of the placement groove 12, so as to accurately position the second workpiece 300 to the preset position of the first workpiece 200, thereby increasing the adjustment range of positioning;

[0094] Then, an external force is applied to the stopper 40 to make it abut against the adjusted adjusting member 32 to stop the adjusting member 32, thereby preventing the rotating member 33 and the adjusting member 32 from rotating due to interference from external force factors and causing the positioning position of the second workpiece 300 to deviate from the preset position, which is conducive to improving the positioning stability;

[0095] Finally, after the first workpiece 200 and the second workpiece 300 are processed and removed after positioning, an external force is applied to the stop member 40 to disengage it from the adjusting member 32, and the rotating member 33 is rotated clockwise or counterclockwise so that the compressed elastic member 22 provides elastic force and cooperates with the adjusting member 32 to drive the sliding block 211 to return to its initial position, so that the positioning device 100 can repeat the positioning operation.

[0096] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and not to limit them. Although the present application has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present application can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present application.
