[0037] Referring to Figure 1 and Figure 3 , the positioning assembly 10 comprises a bearing member 11, a first positioning member 12, a second positioning member 13 and a third positioning member 14. The bearing member 11 is used for bearing the workpiece 200. The first positioning member 12 is connected with the bearing member 11. The second positioning member 13 is spaced apart from the first positioning member 12 along the first direction. The second positioning member 13 and the third positioning member 14 are oppositely arranged along the second direction and are both connected with the bearing member 11. The first positioning member 12, the second positioning member 13 and the third positioning member 14 all comprise a fixed body 121 and a positioning body 122. The fixed body 121 is connected with the bearing member 11. The positioning body 122 is movably arranged in the fixed body 121 and is elastically connected with the fixed body 121. The riveting assembly 20 comprises a moving member 21, a reference member 22, a first pushing member 23, a second pushing member 24, a pushing member 25 and a riveting member 26. The reference member 22, the first pushing member 23, the second pushing member 24, the pushing member 25 and the riveting member 26 are all connected with the moving member 21. The moving member 21 is movably arranged above the bearing member 11. The reference member 22 and the first pushing member 23 are oppositely arranged along the first direction. The reference member 22 is used for being inserted into the bearing member 11 under the driving of the moving member 21. The first pushing member 23 and the first positioning member 12 are oppositely arranged along the third direction. The first pushing member 23 is used for driving the positioning body 122 of the first positioning member 12 to move close to the reference member 22 under the driving of the moving member 21, so as to position the workpiece 200 along the first direction. The second pushing member 24 and the pushing member 25 are oppositely arranged with the second positioning member 13 and the third positioning member 14 along the third direction, respectively. The second pushing member 24 and the pushing member 25 are used for driving the positioning body 122 of the second positioning member 13 and the positioning body 122 of the third positioning member 14 to oppositely move under the driving of the moving member 21, so as to position the workpiece 200 along the second direction. The riveting member 26 is used for adsorbing the small piece 300 and moving close to the positioned workpiece 200, so as to rivet the small piece 300 to the workpiece 200. Exemplarily, the riveting member 26 can be a riveting punch.

[0038] The riveting device 100 described above, in actual use, first, the bearing member 11 bears the workpiece 200, then the moving member 21 drives the reference member 22, the first pushing member 23, the second pushing member 24 and the pushing member 25 to move close to the bearing member 11, the reference member 22 abuts against the side wall of the workpiece 200 along the first direction, the first pushing member 23 drives the positioning body 122 of the first positioning member 12 to move close to the reference member 22 to position the workpiece 200 along the first direction, the second pushing member 24 and the pushing member 25 respectively drive the positioning body 122 of the second positioning member 13 and the positioning body 122 of the third positioning member 14 to move relatively to position the workpiece 200 along the second direction, so as to position the workpiece 200 along the first direction and the second direction at the same time, finally, the riveting member 26 drives the adsorbed small workpiece 300 to move close to the bearing member 11 to rivet the small workpiece 300 to the preset position of the workpiece 200. In this way, the positioning body 122 of the first positioning member 12 moves close to the reference member 22 to position the workpiece 200 along the first direction, the positioning body 122 of the second positioning member 13 and the positioning body 122 of the third positioning member 14 move relatively to position the workpiece 200 along the second direction, so as to position the workpiece 200 along the first direction and the second direction at the same time, which is suitable for different types of workpieces 200, improves the positioning precision, and further improves the riveting precision of the workpiece 200.

[0039] Please refer to Figure 3 In some embodiments, the fixed body 121 is provided with a limiting groove 1211, the positioning body 122 includes an elastic part 1221, a positioning part 1222, an abutting part 1223 and a stop part 1224, the elastic part 1221 is arranged in the limiting groove 1211, the positioning part 1222 is movably arranged in the elastic part 1221, one end of the abutting part 1223 is movably arranged in the limiting groove 1211 and connected with the positioning part 1222, the other end of the abutting part 1223 extends out of the limiting groove 1211, the abutting part 1223 abuts against both ends of the elastic part 1221 respectively, the abutting part 1223 is used for compressing the elastic part 1221 to the groove wall of the limiting groove 1211, and driving the positioning part 1222 to extend out of the limiting groove 1211 to position the workpiece 200, the stop part 1224 is connected with the fixed body 121, and the stop part 1224 is used for abutting against one end of the abutting part 1223 away from the positioning part 1222 to limit the abutting part 1223. Exemplarily, the elastic part 1221 can be a spring.

[0040] Thus, by setting the specific structure of the positioning body 122, when the abutting portion 1223 is subjected to the pushing force applied by the riveting assembly 20, the elastic portion 1221 is compressed to the groove wall of the limiting groove 1211, and the positioning portion 1222 is driven to extend out of the limiting groove 1211 to position the workpiece 200. After the riveting operation of the workpiece 200 is completed, the riveting assembly 20 cancels the pushing force applied to the abutting portion 1223, the elastic portion 1221 is elastically expanded and drives the abutting portion 1223 to reset, so that the end of the abutting portion 1223 away from the elastic portion 1221 extends out of the limiting groove 1211, and the stop portion 1224 abuts against the abutting portion 1223 to limit the length of the abutting portion 1223 extending out of the limiting groove 1211, facilitating the first pushing member 23, the second pushing member 24 and the abutting member 25 of the riveting assembly 20 to repeatedly push the corresponding abutting portion 1223.

[0041] In some embodiments, the groove wall of the limiting groove 1211 is provided with a sliding groove 1212, and the positioning body 122 further comprises a sliding portion 1225 protruding from the side wall of the abutting portion 1223 and in sliding connection with the sliding groove 1212. The sliding portion 1225 is used to slide in the sliding groove 1212 to guide the movement direction of the abutting portion 1223.

[0042] Thus, by setting the sliding connection between the sliding portion 1225 and the sliding groove 1212, after the abutting portion 1223 is subjected to the pushing force applied by the riveting assembly 20, the sliding portion 1225 slides in the sliding groove 1212 to guide the movement direction of the abutting portion 1223, ensuring that the abutting portion 1223 stably drives the positioning portion 1222 to extend out of the limiting groove 1211 and position the workpiece 200, thereby improving the positioning stability.

[0043] In some embodiments, the side of the abutting portion 1223 away from the positioning portion 1222 is provided with a stress inclined surface 1223a, which is inclined relative to the third direction. The stress inclined surface 1223a is used to drive the abutting portion 1223 to move away from the stop portion 1224 under the pushing of the first pushing member 23, the second pushing member 24 or the abutting member 25.

[0044] Thus, by setting the stress inclined surface 1223a, the first pushing member 23, the second pushing member 24 and the abutting member 25 are respectively in inclined abutment with the corresponding abutting portion 1223, which is conducive to stably pushing the abutting portion 1223 by the first pushing member 23, the second pushing member 24 and the abutting member 25.

[0045] Please refer to Figure 1 and Figure 4In some embodiments, the first pushing member 23 and the second pushing member 24 comprise a rotating body 231 and an elastic body 232. The rotating body 231 is rotationally connected with the moving member 21, and two ends of the elastic body 232 are elastically abutted against the moving member 21 and the rotating body 231 away from the carrier 11, respectively. The rotating body 231 is used to push the positioning body 122 under the driving of the moving member 21 and rotate relative to the moving member 21, so as to compress the elastic body 232 to the moving member 21. Exemplarily, the elastic body 232 can be a spring.

[0046] In this way, by setting the specific structure of the first pushing member 23 and the second pushing member 24, when the rotating body 231 pushes the corresponding positioning body 122, the rotating body 231 is subjected to the reaction force of the positioning body 122 and compresses the elastic body 232 to the moving member 21, so that the elastic body 232 absorbs the excessive pushing force of the rotating body 231 applied to the positioning body 122, and ensures that the rotating body 231 smoothly and stably pushes the positioning body 122.

[0047] Please refer to Figure 4 In some embodiments, the pushing member 25 comprises a linkage body 251, a pushing body 252 and a limiting body 253. The linkage body 251 is connected with the moving member 21, the pushing body 252 is arranged opposite to the third positioning member 14 and connected with the linkage body 251, and the limiting body 253 is arranged on the linkage body 251 away from the pushing body 252 and adjacent to the second positioning member 13. The limiting body 253 is used to abut against the workpiece 200 to limit the workpiece 200 to a preset orientation.

[0048] In this way, by setting the specific structure of the pushing member 25, the pushing body 252 pushes the positioning body 122 of the third positioning member 14 under the driving of the linkage body 251, so that the positioning body 122 of the third positioning member 14 and the positioning body 122 of the second positioning member 13 clamp the workpiece 200 along the second direction, and the workpiece 200 is positioned along the second direction. In addition, the limiting body 253 is arranged on the linkage body 251 away from the pushing body 252, so that the pushing member 25 is reasonably arranged, and the limiting body 253 does not collide with the third positioning member 14. Since the workpiece 200 may be in an inclined state due to its center of gravity, placement error or other reasons during placement on the carrier 11, the limiting body 253 abuts against the workpiece 200 in the inclined state under the driving of the linkage body 251, so as to guide the workpiece 200 to a horizontal state, and facilitate the subsequent positioning and riveting operation of the riveting device 100 on the workpiece 200.

[0049] In the embodiment, the pushing member 25 is fixedly connected with the moving member 21, and the rotating body 231 of the second pushing member 24 is in abutment with the moving member 21 through the elastic body 232 away from the one end of the bearing member 11. Thus, when positioning the workpiece 200 with the tolerance in the second direction, the positioning body 122 of the third positioning member 14 is pushed by the pushing member 25 to push the workpiece 200 to move close to the positioning body 122 of the second positioning member 13, so that the positioning body 122 of the second positioning member 13 exerts a reaction force to the rotating body 231 of the second pushing member 24, and the rotating body 231 of the second pushing member 24 rotates relative to the moving member 21 and presses the elastic body 232 of the second pushing member 24 to the moving member 21, so that the elastic body 232 offsets the tolerance of the workpiece 200 by elastic deformation. It can be understood that the positioning process of the first positioning member 12 and the reference member 22 is substantially the same, which will not be described here.

[0050] Referring to Figure 1 and Figure 5 In some embodiments, the positioning assembly 10 further comprises two limiting members 15, which are oppositely arranged along the first direction and are both connected to the bearing member 11, and the two limiting members 15 are used to limit the workpiece 200 carried by the bearing member 11.

[0051] Thus, by arranging the above-mentioned limiting member 15, when the workpiece 200 is placed on the bearing member 11, the two limiting members 15 limit the workpiece 200 along the first direction, avoiding the workpiece 200 from swinging or shaking greatly before positioning, and ensuring that the first positioning member 12, the reference member 22, the second positioning member 13 and the third positioning member 14 stably position the workpiece 200.

[0052] Referring to Figure 5 In some embodiments, the side of the limiting member 15 towards the first positioning member 12 is provided with a guide inclined surface 151 and an abutting plane 152, the guide inclined surface 151 is arranged obliquely, one end of the guide inclined surface 151 is connected with the upper surface of the reference member 22 in an arc transition, the other end of the guide inclined surface 151 is connected with the abutting plane 152, and the guide inclined surface 151 is used to guide the workpiece 200 to move to the bearing member 11, so that the abutting plane 152 is in plane abutment with the side wall of the workpiece 200.

[0053] Thus, by arranging the specific structure of the above-mentioned limiting member 15, the guide inclined surface 151 guides the workpiece 200 to move to the bearing member 11 smoothly, and ensures that the abutting plane 152 is in plane contact with the side wall of the workpiece 200, so that the limiting member 15 stably limits the workpiece 200, and further improves the positioning accuracy of the workpiece 200.

[0054] Referring to Figure 5 In some embodiments, the side of the bearing member 11 towards the moving member 21 is provided with a receiving groove 111 for inserting the reference member 22.

[0055] Thus, by setting the receiving groove 111, the reference piece 22 is inserted into the receiving groove 111 under the driving of the moving piece 21, so that the gap between the reference piece 22 and the upper surface of the bearing piece 11 bearing the workpiece 200 is prevented, and the reference piece 22 is ensured to stably position the workpiece 200.

[0056] Please refer to Figure 1 In some embodiments, the positioning assembly 10 further comprises a guide piece 16 arranged adjacent to the bearing piece 11, and the guide piece 16 is provided with a guide groove 161 on the side facing the moving piece 21. The riveting assembly 20 further comprises a rolling piece 27 rotationally connected with the moving piece 21, and the rolling piece 27 is used to be inserted into the guide groove 161 under the driving of the moving piece 21, so as to guide the movement direction of the reference piece 22, the first pushing piece 23, the second pushing piece 24 and the abutting piece 25.

[0057] Thus, by setting the guide piece 16 and the rolling piece 27, when the moving piece 21 moves close to the bearing piece 11, the rolling piece 27 is inserted into the guide groove 161 to guide the movement direction of the reference piece 22, the first pushing piece 23, the second pushing piece 24 and the abutting piece 25, so as to ensure that the first pushing piece 23, the second pushing piece 24 and the abutting piece 25 accurately push the positioning body 122 of the corresponding positioning piece, and the positioning stability is improved. In addition, the rolling piece 27 is rotationally connected with the moving piece 21, and when the rolling piece 27 is inserted into the guide groove 161, the rolling piece 27 is in rolling contact with the groove wall of the guide groove 161, so as to reduce the friction between the rolling piece 27 and the guide piece 16, and ensure that the rolling piece 27 smoothly slides in the guide groove 161.

[0058] Please continue to refer to Figure 1 In some embodiments, the riveting device 100 further comprises a feeding assembly 30 arranged on one side of the bearing piece 11 and spaced apart by a plurality of positioning grooves 31, and the positioning grooves 31 are used to receive and position small pieces 300.

[0059] Thus, by setting the feeding assembly 30, the feeding assembly 30 receives and positions a plurality of small pieces 300 through a plurality of positioning grooves 31 arranged at intervals, so that the small pieces 300 are ensured to be in a predetermined orientation, and the riveting piece 26 accurately removes the small pieces 300.
