In the prior art, stud press riveting equipment usually realizes the directional sorting and conveying of studs through a vibrating bowl, and then a robotic arm or a pneumatic device transfers the studs to the press riveting station to complete the riveting operation. In the prior art, the automated equipment for stud press riveting requires a large amount of human resources, and there is only one vibrating bowl feeding mechanism for placing materials (studs), resulting in that a single device can only process studs of a single specification within the same production cycle. When it is necessary to switch to studs of different models, the operator must stop the machine and replace the appropriate vibrating bowl. This process takes a long time and requires repeated calibration of the equipment, seriously restricting the production efficiency of stud press riveting. Summary of the Invention

[0022] See Figures 1 to 8 , an automated device for automatic stud press riveting is provided. Among them, the automated device for automatic stud press riveting includes: A plurality of feeding vibrating bowls 1 for conveying studs. The model sizes of the studs conveyed by each feeding vibrating bowl 1 are different. The feeding vibrating bowl 1 itself is a known technology, so no more detailed description will be given; The lower die set. The lower die set includes a support plate 2 for supporting and fixing the workpiece to be stud press riveted. The workpiece is, for example, a perforated plate, etc. A suction cup 3 (such as a vacuum suction cup) for adsorbing and fixing the workpiece can be provided on the support plate 2, or other structures (elements) can also be used to fix the workpiece; The upper die set, including a first electric control motion mechanism, a second electric control motion mechanism, a stud receiving and limiting mechanism 200 connected to the first electric control motion mechanism, and a press riveting implementation mechanism connected to the second electric control motion mechanism. The press riveting implementation mechanism is, for example, a lifting cylinder type press riveting machine 100. The lifting cylinder type press riveting machine 100 has a telescopic extending rod 101, and the end of the extending rod 101 is a press riveting head 102. The stud receiving and limiting mechanism 200 can simultaneously receive and limit studs of different model sizes conveyed by each feeding vibrating bowl 1. The first electric control motion mechanism can drive the stud receiving and limiting mechanism 200 to move to the press riveting working position. The second electric control motion mechanism can drive the press riveting implementation mechanism to reach the press riveting working position and press rivet the studs on the stud receiving and limiting mechanism 200 at the press riveting working position to the workpiece. When the extending rod 101 of the lifting cylinder type press riveting machine 100 moves downward, the press riveting head 102 can press rivet the studs to the workpiece.

[0023] In the automated equipment for automatic stud press riveting provided by the embodiments of the present invention, there are multiple feeding vibrating bowls 1 for conveying studs. The model sizes of the studs conveyed by each feeding vibrating bowl 1 are different. The stud receiving and limiting mechanism 200 in the upper die set can simultaneously receive and limit the studs with different model sizes conveyed by each feeding vibrating bowl 1. Therefore, the automated equipment for automatic stud press riveting can simultaneously convey multiple model sizes of studs to the stud receiving and limiting mechanism 200, and then the press riveting implementation mechanism sequentially presses all the studs with different model sizes on the stud receiving and limiting mechanism 200 onto the target workpiece within the same production cycle, thereby greatly improving the versatility, multi-specification adaptability, and stud press riveting work efficiency of the stud press riveting operation.

[0024] According to an embodiment of the present application, the automated equipment for automatic stud press riveting includes a discharge table 4. The discharge table 4 is provided with discharge connecting pipes 5 having the same number as the feeding vibrating bowls 1. Each discharge connecting pipe 5 penetrates downward through the discharge table 4, and the axis of the discharge connecting pipe 5 is arranged in the vertical direction. The discharge ends of each feeding vibrating bowl 1 are respectively connected to each discharge connecting pipe 5 through a hose (not shown). The stud receiving and limiting mechanism 200 has a plurality of upper stud receiving and limiting holes 201, and the axis of the upper stud receiving and limiting holes 201 is arranged in the vertical direction. The number of the plurality of upper stud receiving and limiting holes 201 is greater than or equal to the number of the discharge connecting pipes 5. The first electric control motion mechanism can drive the stud receiving and limiting mechanism 200 to move to the stud receiving position located below the discharge table 4. When the stud receiving and limiting mechanism 200 is in the stud receiving position, each discharge connecting pipe 5 can simultaneously output studs into the corresponding upper stud receiving and limiting holes 201 on the stud receiving and limiting mechanism 200. For example, when the stud receiving and limiting mechanism 200 is in the stud receiving position and the discharge connecting pipes 5 are arranged in a circular pattern, there is a corresponding upper stud receiving and limiting hole 201 below each discharge connecting pipe 5 on the corresponding circular trajectory. When the discharge connecting pipes 5 are arranged in a straight line pattern, there is a corresponding upper stud receiving and limiting hole 201 below each discharge connecting pipe 5 on the corresponding straight line trajectory.

[0025] According to a specific embodiment of the present application, a stud receiving and limiting mechanism 200 includes a receiving seat, and a plurality of groups of upper stud receiving and limiting holes 201 are arranged at intervals along a circular trajectory on the receiving seat, and the receiving seat has at least a first hole arrangement state. In the first hole arrangement state, each group of upper stud receiving and limiting holes 201 has a plurality of upper stud receiving and limiting holes 201 with the same aperture, and the apertures of the upper stud receiving and limiting holes 201 in different groups gradually increase along the circular trajectory. The discharge pipe 5 is arranged at intervals along a circular trajectory corresponding to the arrangement direction of the upper stud receiving and limiting holes 201 on the discharge platform 4, and the apertures of each discharge pipe 5 gradually increase along the arrangement direction of the discharge pipe 5. The discharge pipes 5 with different apertures and the upper stud receiving and limiting holes 201 with different apertures are all arranged in the same form and trajectory, so that the discharge pipe 5 can quickly and conveniently transport the studs to the corresponding upper stud receiving and limiting holes 201.

[0026] In this embodiment, the upper stud receiving limit holes 201 and the discharge pipe 5 are distributed along a circular trajectory. Compared with the case of being arranged along a straight line, more upper stud receiving limit holes 201 can be arranged within a smaller length range, thereby facilitating the stud receiving limit mechanism 200 to receive as many studs as possible at one time for the riveting implementation mechanism to perform riveting operations.

[0027] As other embodiments, the apertures of the upper stud-supporting limiting holes 201 and the discharge pipe 5 may not necessarily increase gradually along the corresponding circular trajectory, and may also be arranged randomly.

[0028] According to one embodiment of the present application, an automated device for automatic production of stud riveting includes a first lifting drive mechanism 6 and a first rotating drive mechanism 7 connected to the first lifting drive mechanism 6, a discharge table 4 is connected to the first rotating drive mechanism 7, the first lifting drive mechanism 6 can drive the first rotating drive mechanism 7 to lift and lower to drive the discharge table 4 to lift and lower to a position adjacent to a stud receiving limit mechanism 200, the first rotating drive mechanism 7 can drive the discharge table 4 to rotate so that the discharge pipe 5 is aligned with the corresponding upper stud receiving limit hole 201, the first lifting drive mechanism 6 is, for example, a vertical electric guide rail or the like, the slider portion of the vertical electric guide rail (first lifting drive mechanism 6) is connected to a lifting frame 22, the first rotating drive mechanism 7 is a stepping motor capable of precisely controlling an angle, the main body of the stepping motor is connected to the lifting frame 22, and the axis of the discharge table 4 is connected to the input of the stepping motor. The output shaft, for example, has 8 groups of upper stud receiving limit holes 201 and each group has two upper stud receiving limit holes 201 with the same aperture, then there are a total of 16 upper stud receiving limit holes 201, and there are 8 corresponding discharge pipes 5. If the 16 upper stud receiving limit holes 201 are arranged at equal angles α1, and the 8 discharge pipes 5 are arranged at an angle α2 that is twice the arrangement angle of the 16 upper stud receiving limit holes 201, then after the 8 discharge pipes 5 output studs to one upper stud receiving limit hole 201 in the 8 groups of upper stud receiving limit holes 201 respectively, the stepper motor only needs to drive the discharge platform 4 to rotate the angle α1 to output studs to the other 8 upper stud receiving limit holes 201, thereby achieving the output of studs to 16 upper stud receiving limit holes 201 twice, which greatly improves the efficiency of outputting studs for the stud receiving limit mechanism 200.

[0029] According to a specific embodiment of the present application, the receiving seat includes a central disk 202 and a rotating ring 203 that surrounds the outer circumference of the central disk 202 at intervals. The outer circumference of the central disk 202 has first half holes 204 corresponding to the number of upper stud receiving limit holes 201, and the inner circumference of the rotating ring 203 has second half holes 205 corresponding to the number of upper stud receiving limit holes 201. The first half holes 204 and the second half holes 205 surround the upper stud receiving limit holes 201, and the rotating ring 203 can rotate around the axis of the central disk 202 so that each first half hole 204 can be combined with any second half hole 205 to form different upper studs. The receiving limit hole 201, when the receiving seat is in the first hole arrangement state, when the rotating ring 203 is in the initial position, each first half hole 204 and the second half hole 205 of the same aperture surround the upper stud receiving limit hole 201, after the rotating ring 203 rotates relative to the initial position, the first half hole 204 may be combined with the second half hole 205 of a larger or smaller aperture to form a new upper stud receiving limit hole 201, at this time, the size of the half hole with a smaller aperture is used as the standard to accept the stud of the corresponding size. The advantage of this design is that, according to the specific situation of the workpiece to be riveted with the stud, more studs of a certain size may be required during the stud riveting operation, or some If studs of different sizes are not needed, the rotating ring 203 can be rotated as needed to adjust the number of studs of different sizes received by the receiving seat. For example, if there are 8 groups of upper stud receiving limit holes 201 and each group has two upper stud receiving limit holes 201 with the same aperture, there are a total of 16 upper stud receiving limit holes 201, and there are 8 corresponding discharge pipes 5. If the 16 upper stud receiving limit holes 201 are arranged at equal angles α1, and the 8 discharge pipes 5 are arranged at an angle α2 that is twice the arrangement angle of the 16 upper stud receiving limit holes 201, more studs are needed for the upper stud receiving limit holes 201 with the smallest aperture. When the rotating ring 203 is rotated by an angle α1 along the direction in which the upper stud receiving limiting hole 201 is distributed from the smallest to the least, the receiving seat is in the second hole arrangement state and can accept 3 studs of the smallest size, and only accept 1 stud of the largest size. The receiving seat can still accept 2 studs of other aperture sizes respectively, and the rotating ring 203 continues to be rotated by an angle α1 along the same direction, so that 4 studs of the smallest size can be accepted, and the stud of the largest size is not accepted at this time. The operation is performed by analogy, and the number of studs of different sizes received by the receiving seat can be adjusted, thereby further improving the stud distribution efficiency and the working efficiency of stud riveting.

[0030] According to a specific embodiment of the present application, the stud receiving and limiting mechanism 200 includes a support disk 206 connected to the first electric control movement mechanism. The central disk 202 is fixedly supported on the support disk 206, and the rotating ring 203 is rotatably supported on the support disk 206. Specifically, the central disk 202 is fixedly connected to the axis of the support disk 206 through the mounting posts 214 on the support disk 206. An annular guide rail 207 is provided on the support disk 206, and an annular guide groove 208 adapted to the annular guide rail 207 is formed below the rotating ring 203. Lower stud receiving and limiting holes 209 corresponding to the number and positions of the upper stud receiving and limiting holes 201 are provided on the support disk 206. The support disk 206 is provided with elastic resisting members protruding from the hole walls of the respective lower stud receiving and limiting holes 209. The stud can pass through the corresponding upper stud receiving and limiting hole 201 and be supported on the elastic resisting member in the corresponding lower stud receiving and limiting hole 209. The riveting implementation mechanism can press down the stud in the upper stud receiving and limiting hole 201 and the lower stud receiving and limiting hole 209, so that the stud squeezes the elastic resisting member to retract into the hole wall of the lower stud receiving and limiting hole 209 and fall onto the workpiece to be stud-riveted. The elastic resisting member includes an elastic column 210, a receiving cavity 212 is formed in the hole wall, and a spring 211 connected to the elastic column 210 is provided in the receiving cavity 212.

[0031] In this embodiment, lower stud receiving and limiting holes 209 corresponding to the number, hole diameters and positions of the upper stud receiving and limiting holes 201 are provided on the support disk 206. Specifically, it can be understood that, for example, when the receiving seat is in the first hole arrangement state, if there are 8 groups of upper stud receiving and limiting holes 201 and each group has two upper stud receiving and limiting holes 201 with the same hole diameter, then there are a total of 16 upper stud receiving and limiting holes 201. Then, 16 lower stud receiving and limiting holes 209 that are vertically aligned with the 16 upper stud receiving and limiting holes 201 are provided on the support disk 206, and the hole diameters of the vertically aligned stud receiving and limiting holes and the lower stud receiving and limiting holes 209 are the same.

Each set of upper stud receiving limit holes 201 may have 3 upper stud receiving limit holes 201 with the same aperture or more upper stud receiving limit holes 201. Of course, the lower stud receiving limit holes 209 on the support plate 206 should also be designed adaptively.

The support frame 8 is connected to the second lifting drive mechanism 14. After the stud press riveting operation is completed, the second lifting drive mechanism 14 drives the support frame 8 to rise, so that the stud can be disengaged from the limits of the support plate 206 and the receiving seat, facilitating the removal of the workpiece on the support plate 2 that has completed stud press riveting. The first horizontal electric guide rail 11 extends along the length direction of the installation base 300, and the second horizontal electric guide rail 12 extends along the width direction of the installation base 300.
