[0035] See also Figures 1 to 8 , provides an automated equipment for automatic production of stud riveting, wherein the automated equipment for automatic production of stud riveting includes:

[0036] Multiple feeding vibration plates 1 for conveying studs, each feeding vibration plate 1 conveys studs of different models and sizes. The feeding vibration plate 1 itself is a known technology, so it will not be described in detail.

[0037] The lower die assembly includes a support plate 2 for supporting and fixing a workpiece to be riveted with studs. The workpiece may be, for example, a sheet metal with holes. The support plate 2 may be provided with a suction cup 3 (e.g., a vacuum suction cup) for adsorbing and fixing the workpiece, or other structures (elements) may be used to fix the workpiece;

[0038] The upper mold assembly includes a first electrically-controlled motion mechanism, a second electrically-controlled motion mechanism, a stud receiving and limiting mechanism 200 connected to the first electrically-controlled motion mechanism, and a riveting implementation mechanism connected to the second electrically-controlled motion mechanism. The riveting implementation mechanism is, for example, a lifting cylinder riveting machine 100. The lifting cylinder riveting machine 100 has a retractable extension rod 101, and the end of the extension rod 101 is a riveting head 102. The stud receiving and limiting mechanism 200 can simultaneously receive and limit studs of different models and sizes conveyed by each feeding vibration plate 1. The first electrically-controlled motion mechanism can drive the stud receiving and limiting mechanism 200 to move to the riveting working position. The second electrically-controlled motion mechanism can drive the riveting implementation mechanism to arrive at the riveting working position and rivet the stud on the stud receiving and limiting mechanism 200 in the riveting working position to the workpiece. The downward movement of the extension rod 101 of the lifting cylinder riveting machine 100 can enable the riveting head 102 to rivet the stud to the workpiece.

[0039] Since the automated equipment for automatic production of stud riveting provided by the embodiment of the present invention has multiple feeding vibration plates 1 for conveying studs, and the types and sizes of the studs conveyed by each feeding vibration plate 1 are different, the stud receiving and limiting mechanism 200 in the upper module can simultaneously receive and limit the studs of different types and sizes conveyed by each feeding vibration plate 1, so the automated equipment for automatic production of stud riveting can simultaneously convey studs of multiple types and sizes to the stud receiving and limiting mechanism 200, and then through the riveting implementation mechanism, all the studs of different types and sizes on the stud receiving and limiting mechanism 200 are riveted to the target workpiece in sequence within the same production cycle, thereby greatly improving the versatility, multi-specification adaptability and stud riveting work efficiency of the stud riveting operation.

[0040] According to one embodiment of the present application, the automated equipment for automatic production of stud riveting includes a discharge table 4, and the discharge table 4 is provided with discharge pipes 5 with the same number as the feeding vibration disk 1. Each discharge pipe 5 passes through the discharge table 4 downward, and the axis of the discharge pipe 5 is arranged in the vertical direction. The discharge ends of each feeding vibration disk 1 are connected to each discharge pipe 5 one by one through a hose (not shown). The stud receiving limit mechanism 200 has a plurality of upper stud receiving limit holes 201, and the axes of the upper stud receiving limit holes 201 are arranged in the vertical direction. The number of the plurality of upper stud receiving limit holes 201 is greater than or equal to the number of the discharge pipes 5. The first electric control motion mechanism can drive the stud The column receiving and limiting mechanism 200 moves to the stud receiving position located below the discharge platform 4. When the stud receiving and limiting mechanism 200 is located at the stud receiving position, each discharge pipe 5 can simultaneously output the stud to the corresponding upper stud receiving and limiting hole 201 on the stud receiving and limiting mechanism 200. For example, when the stud receiving and limiting mechanism 200 is located at the stud receiving position, when each discharge pipe 5 is arranged along the circumference, there is a corresponding upper stud receiving and limiting hole 201 below each discharge pipe 5 on the corresponding circumferential trajectory. When each discharge pipe 5 is arranged along a straight line, there is a corresponding upper stud receiving and limiting hole 201 below each discharge pipe 5 on the corresponding straight line trajectory.

[0041] According to a specific embodiment of the present application, the stud receiving and limiting mechanism 200 includes a receiving seat, and multiple groups of upper stud receiving and limiting holes 201 are arranged at intervals along a circular trajectory on the receiving seat. 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 multiple upper stud receiving and limiting holes 201 with the same aperture. 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 table 4. The aperture of each discharge pipe 5 gradually increases 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, which facilitates the discharge pipe 5 to quickly and conveniently transport the studs to the corresponding upper stud receiving and limiting holes 201.

[0042] 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.

[0043] As other embodiments, the apertures of the upper stud receiving limiting holes 201 and the discharge pipe 5 may not necessarily increase gradually along the corresponding circular trajectory, and may also be arranged randomly.

[0044] According to one embodiment of the present application, the automated equipment for automatic production of stud riveting includes a first lifting drive mechanism 6 and a first rotary drive mechanism 7 connected to the first lifting drive mechanism 6, the discharge table 4 is connected to the first rotary drive mechanism 7, the first lifting drive mechanism 6 can drive the first rotary drive mechanism 7 to lift and lower to drive the discharge table 4 to lift and lower to a position adjacent to the stud receiving limit mechanism 200, the first rotary 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 other mechanism, the slider portion of the vertical electric guide rail (first lifting drive mechanism 6) is connected to the lifting frame 22, the first rotary drive mechanism 7 is a stepper motor that can accurately control the angle, the main body of the stepper motor is connected to the lifting frame 22, and the axis of the discharge table 4 is connected to the output of the stepper motor. Outgoing shaft, for example, 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, 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, the stepper motor only needs to drive the discharge table 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 the 16 upper stud receiving limit holes 201 twice, which greatly improves the efficiency of outputting studs for the stud receiving limit mechanism 200.

[0045] 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 a first half hole 204 corresponding to the number of the upper stud receiving limit holes 201, and the inner circumference of the rotating ring 203 has a second half hole 205 corresponding to the number of the upper stud receiving limit holes 201. The first half hole 204 and the second half hole 205 surround the upper stud receiving limit hole 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 a different upper stud. When the receiving seat is in the first hole arrangement state and 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 larger or smaller aperture to form a new upper stud receiving limit hole 201. At this time, the size of the half hole with smaller aperture is used as the standard to accept the stud of corresponding size. The advantage of this design is that, according to the specific situation of the workpiece to be riveted, more studs of a certain size may be required during the stud riveting operation, or certain 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 of the upper stud receiving limiting hole 201 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. The rotating ring 203 is continued to be rotated by an angle α1 along the same direction, and can accept 4 studs of the smallest size. At this time, the stud of the largest size is not accepted. The operation is performed in this way, 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.
