They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0043] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Furthermore, the terms "first" and "second" are used merely for descriptive distinction and have no specific meaning.
[0044] In one embodiment of this utility model, such as Figure 1-6 As shown, a riveting device is provided, including: a worktable 1, a turntable 2, a working station 3, a mounting base 8, and a robotic arm 304. The turntable 2 and the working station 3 are both positioned on the top surface of the worktable 1. The working station 3 includes a loading station 301, a riveting station 302, and a discharging station 303, which are sequentially arranged on the worktable 1 along the working rotation direction of the turntable 2. The mounting base 8 is positioned on the turntable 2, and the rotation of the turntable 2 causes the mounting base 8 to sequentially stop at the loading station 301, the riveting station 302, and the discharging station 304. Position 303, mounting base 8 has mounting slot 9; riveting station 302 includes riveting block 321 and mating slot 322, the riveting block 321 is set on the worktable 1 for lifting and riveting movement along the mounting base 8, the mating slot 322 is set on the bottom surface of the riveting block 321 and mats with the mounting slot 9; robot arm 304 is positioned on the worktable 1 and reciprocates between work station 3 and mounting base 8.
[0045] The riveting equipment provided by this utility model automatically rotates the mounting base 8 between different workstations 3 via the turntable 2, realizing automated operation of workpiece loading, riveting, and unloading, reducing manual intervention and significantly improving production efficiency. The mounting clamp 9 and the riveting station 302 cooperate with the clamp 322 to ensure precise workpiece positioning, reducing quality problems caused by positioning deviations and improving product processing accuracy and quality stability. The equipped robotic arm 304 can flexibly transport workpieces, making the production process more compact and smooth, further enhancing equipment operating efficiency.
[0046] The robotic arm 304 includes an X-axis module 341, a Z-axis module 342, and a riveting module 343. The positioning end of the X-axis module 341 is positioned on the worktable 1, and its driving end moves along the X-axis. The positioning end of the Z-axis module 342 is positioned on the driving end of the X-axis module 341, and its driving end moves along the Z-axis. The positioning end of the riveting module 343 is positioned on the driving end of the Z-axis module 342, and its driving end moves along the riveting direction. The combination of the X-axis, Z-axis, and riveting modules 343 allows the robotic arm 304 to move flexibly in three-dimensional space, meeting diverse needs such as loading, unloading, and workpiece transfer. Compared to single-direction or two-axis motion structures, this significantly expands the operating range and flexibility.
[0047] Specifically, the robotic arm 304 also includes a first suction head 344 and a second suction head 345. The first suction head 344 is positioned at the drive end of the Z-axis module 342, and the second suction head 345 is positioned at the drive end of the riveting module 343. The first suction head 344 and the second suction head 345 can simultaneously pick up different workpieces, which speeds up the operation rhythm and increases the workpiece processing volume per unit time.
[0048] Furthermore, both the first suction head 344 and the second suction head 345 include connecting rods 346 and suction holes 349. Several connecting rods 346 are provided, arranged radially, and are respectively located at the drive end of the Z-axis module 342 and the drive end of the riveting-axis module 343. Suction holes 349 are formed on the bottom surface of the connecting rods 346.
[0049] Several connecting rods 346 are arranged radially, making the suction head suitable for picking up workpieces with complex or irregular shapes. When the suction head contacts the workpiece, it effectively increases the contact area for picking up the workpiece, while distributing the load and reducing the risk of displacement or tipping caused by single-point force, thus ensuring stability during operation.
[0050] The suction hole 349 is located on the bottom surface of the connecting rod 346, directly facing the workpiece to be adsorbed, which improves the adsorption efficiency. It ensures the effective transmission of suction force and also makes the suction force more concentrated, which helps to quickly and firmly adsorb the workpiece.
[0051] In practical use, the suction hole 349 and connecting rod 346 are equivalent to a suction cup. The suction hole 349 is connected to the air pipe, which can then be connected to an external vacuum generator (such as a vacuum pump). When the vacuum generator is started, a negative pressure will be generated at the suction hole 349, thereby achieving the adsorption operation of the workpiece.
[0052] Furthermore, a protrusion 347 is provided at the radial center of the plurality of connecting rods 346, and a positioning block 348 is provided on the top surface of the mounting slot 9 for engaging with the protrusion 347. The engagement of the protrusion 347 and the positioning block 348 provides a precise positioning reference between the mounting base 8 and the suction head. When the suction head descends and approaches the mounting base 8, the protrusion 347 accurately inserts into the positioning block 348. This ensures that the workpiece can be accurately placed into or removed from the mounting slot 9, avoiding problems caused by positional deviations and improving machining accuracy and quality.
[0053] Preferably, the loading station 301 includes a vibration source 311 and a direct vibrator 312. Both the vibration source 311 and the direct vibrator 312 are mounted on the worktable 1, and the vibration conveying end of the direct vibrator 312 is electrically connected to the vibration conveying end of the vibration source 311. A robotic arm 304 reciprocates between the vibration conveying end of the direct vibrator 312 and the mounting position 9 of the mounting base. The vibration source 311 and the direct vibrator 312 work together to continuously convey the workpiece to be processed along the vibration conveying end to the predetermined position, ensuring the continuity and stability of material supply and reducing downtime caused by manual intervention or material shortages.
[0054] The riveting equipment also includes a drive assembly 4 to drive the riveting block 321 to perform riveting motion. The drive assembly 4 includes a drive source 401 and a bracket 402. The bracket 402 is positioned on the worktable 1, and the drive source 401 is positioned on the bracket 402. The drive source 401 is connected to the riveting block 321. During the riveting operation, the drive source 401 can be driven to perform a downward movement to extrude and shape the workpiece. Please supplement the corresponding beneficial effects.
[0055] In this embodiment, a cylinder can be used as the drive source 401, or as the power source to drive the X-axis module 341, Z-axis module 342, and riveting module 343. During use, guide rails can be installed to assist movement and improve accuracy. Please add corresponding beneficial effects.
[0056] This riveting device also includes a guide assembly 5, which assists the riveting block 321 in performing the riveting operation. The guide assembly 5 is disposed between the mounting base 8 and the riveting block 321. The guide assembly 5 ensures that the riveting block 321 moves precisely along a predetermined path during the riveting operation, thereby improving the processing accuracy of the product.
[0057] Specifically, the guide assembly 5 includes a guide post 501 and a guide hole 502. The guide post 501 is positioned on the bottom surface of the riveting block 321, and the guide hole 502 is located on the top surface of the mounting base. When the riveting block 321 moves up and down, the guide post 501 moves precisely along the guide hole 502, ensuring the vertical movement path of the riveting block 321 and greatly improving the accuracy of the riveting position. This effectively avoids poor riveting caused by offset or tilt, improving the processing accuracy and consistency of the product.
[0058] The riveting equipment also includes a feeding ramp 6, which is inclinedly set at the discharge station 303 and positioned between the worktable 1 and the mounting base 8. After processing, the workpiece can be smoothly discharged along the ramp, which speeds up the discharge speed.
[0059] This riveting equipment also includes a protective cover 7, positioned on the workbench 1, which covers the turntable 2, the work station 3, and the mounting base 8. The protective cover 7 can prevent external dust, particles, and other pollutants from entering the equipment, maintaining the cleanliness of the working environment. Moreover, the protective cover 7 can encourage operators to follow correct operating procedures, improving the overall operational standardization and safety.
[0060] The riveting process of the workpiece in this utility model is as follows: The workpiece to be processed is placed in the vibration source 311 of the loading station 301. It is conveyed by the vibration source 311 and the direct vibrator 312 in coordination. The workpiece moves along the conveying track to the designated position at the end of the direct vibrator 312. At this time, the first suction head 344 and the second suction head 345 of the robot arm 304 are driven by the X-axis, riveting direction and Z-axis modules 342 to move above the discharge port of the direct vibrator 312. The suction hole 349 is connected to the vacuum generator through the air pipe to generate negative pressure and adsorb and grab the workpiece. Then, the robot arm 304 transfers the workpiece to the mounting position 9 of the mounting seat 8 on the turntable 2. The vacuum device is turned off and the workpiece is accurately positioned. The positioning block 348 on the top surface of the mounting seat 8 cooperates with the protrusion 347 at the radial center of the suction head connecting rod 346 to ensure the positioning accuracy of the workpiece.
[0061] The turntable 2 rotates, causing the mounting base 8 to pass through the riveting station 302 in sequence. Under the drive of the drive component 4 (such as a cylinder), the riveting block 321 descends vertically along the guide component 5 composed of the guide post 501 and the guide hole 502. The mating position 322 on its bottom surface is precisely aligned with the mounting position 9 of the mounting base 8, clamping and fixing the workpiece. Subsequently, the riveting block 321 continues to press down, extruding and shaping the workpiece to complete the riveting process.
[0062] After the riveting is completed, the turntable 2 continues to rotate to the discharge station 303. The robot arm 304 moves again, using the suction head to pick up the finished product and transfer it to the feeding ramp 6. The workpiece automatically slides down the ramp to the collection area. At the same time, the turntable 2 rotates, and the mounting base 8 returns to the loading station 301 to enter the next cycle.
