Description

Technical Field

[0001] This utility model relates to the field of hot riveting technology, and in particular to a rotary hot riveting machine. Background Technology

[0002] Heat staking is a common plastic joining technique that uses heat to soften and reshape plastic rivets (or posts) to secure another part (such as a metal plate, PCB board, or another plastic component). Due to its advantages such as low cost, high reliability, and no need for additional fasteners, this technique is widely used in the assembly of automotive interiors, electronic appliances, medical devices, and home appliance housings.

[0003] Traditional hot riveting equipment works by pressing plastic rivets vertically with a heated riveting head. Although such equipment has a simple structure, in actual production, relying on visual inspection to check the position of the product to be riveted during the riveting and feeding process is very limited. If the problem is not detected and addressed in time, it will lead to defects in the riveted product. Furthermore, after the riveting machine is in operation, the internal temperature of the main body will rise significantly. Excessive temperature can easily damage the internal components of the riveting machine, leading to frequent malfunctions during operation and reducing the practicality of the riveting machine. Therefore, a rotary hot riveting machine is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where visual inspection of the product's position during riveting feeding is insufficient. This limited effectiveness, coupled with the risk of defects in the riveted product if timely detection and intervention are not implemented, leads to significant internal temperature increases during operation. Excessive temperatures can damage internal components, causing malfunctions and reducing the machine's practicality. Therefore, this invention proposes a rotary hot riveting machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A rotary hot riveting machine includes a worktable, inside which are a riveting assembly and a material discharge assembly. A heat dissipation box is fixedly connected to the bottom of the worktable, and a mounting frame is fixedly connected to the bottom wall of the heat dissipation box. A servo motor is fixedly mounted on the top of the mounting frame, and a rotating shaft is fixedly connected to the output end of the servo motor. A rotating disk is fixedly connected to the top of the rotating shaft. Multiple circumferentially distributed placement seats are arranged on the upper surface of the rotating disk. Two support plates are fixedly connected to the top of the rotating disk away from the placement seats. A rotating rod is rotatably connected between the two support plates. A pressure plate is fixedly connected to the outer surface of the rotating rod, and a drive motor is fixedly connected to one side of the outer wall of the rotating rod. A horizontal camera is fixedly connected to the bottom wall inside the worktable away from the material discharge assembly. Multiple telescopic pressure plates are arranged inside the pressure plate. The pressure plate has a positioning function for the workpiece to be riveted, and the position of the workpiece to be riveted is adjusted within the placement seats by the pressure plate.

[0007] Furthermore, the riveting assembly includes a mounting platform, a cylinder is fixedly connected to the top of the mounting platform, and a hot riveting head is fixedly connected to the output end of the cylinder.

[0008] Furthermore, the material discharge assembly includes multiple connecting rods, with a material discharge platform fixedly connected to the bottom of each connecting rod. A material discharge motor is fixedly connected to the outer wall of the material discharge platform, and a threaded rod is fixedly connected to the output end of the material discharge motor. A movable seat is threadedly connected to the outer surface of the threaded rod, and a first electric telescopic rod is fixedly connected to the bottom of the movable seat. A clamping seat is fixedly connected to the bottom of the first electric telescopic rod, and two clamping plates on the clamping seat are adapted to the riveted workpiece.

[0009] Furthermore, a plurality of second electric telescopic rods are fixedly connected to the bottom of the rotating disk, and push plates are fixedly connected to the output ends of the plurality of second electric telescopic rods. The push plates are disposed inside the placement base.

[0010] Furthermore, a discharge conveyor belt is fixedly connected to the bottom wall of the workbench at the end away from the horizontal camera, and the discharge end of the discharge conveyor belt passes through the workbench and extends to the outside.

[0011] Furthermore, a circulating water pump is fixedly connected to the outer wall of the heat sink, and a cooling water pipe is fixedly connected to the output end of the circulating water pump. The outer surface of the cooling water pipe is provided with heat dissipation fins, and two cooling fans are provided on the back of the heat sink.

[0012] Furthermore, the cooling water pipe is located inside the heat sink below the servo motor, which can better dissipate heat from the servo motor and remove heat.

[0013] Furthermore, a temperature sensor is fixedly connected to the top of the mounting bracket, and the temperature sensor is electrically connected to the circulating water pump and two cooling fans.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, during the rotating feeding process, a horizontal camera is used to detect the workpieces to be riveted. When the horizontal camera detects that the workpieces to be riveted are not aligned, the drive motor, rotating rod, and pressure plate work together to adjust and align the workpieces in the placement seat. This ensures that each workpiece can be riveted accurately during the processing, which not only improves the processing accuracy but also reduces the scrap rate, thereby improving production efficiency and product quality.

[0016] 2. In this utility model, the temperature sensor, circulating water pump, cooling water pipes, and heat dissipation fins continuously dissipate heat from the inside of the hot riveting machine, preventing heat buildup during operation and ensuring effective heat dissipation. When the internal temperature of the hot riveting machine rises continuously for a short period, two cooling fans assist in cooling, rapidly reducing the internal temperature and preventing damage to internal components due to excessive heat, which could affect the lifespan of the equipment.

[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Example 1

[0025] like Figure 1 - Figure 5 As shown, the present invention proposes a rotary hot riveting machine, including a worktable 1. The worktable 1 is equipped with a riveting assembly 2 and a material discharge assembly 3. A heat dissipation box 4 is fixedly connected to the bottom of the worktable 1. A mounting frame 5 is fixedly connected to the bottom wall inside the heat dissipation box 4. A servo motor 6 is fixedly installed on the top of the mounting frame 5. A rotating shaft 7 is fixedly connected to the output end of the servo motor 6. A rotating disk 8 is fixedly connected to the top of the rotating shaft 7. A plurality of placement seats 9 are evenly distributed in a circle on the upper surface of the rotating disk 8. Two support plates 10 are fixedly connected to the top of the rotating disk 8 away from the placement seats 9. A rotating rod 11 is rotatably connected between the two support plates 10. A pressure plate 12 is fixedly connected to the outer surface of the rotating rod 11. A drive motor 13 is fixedly connected to one side of the outer wall of the rotating rod 11. A horizontal camera 14 is fixedly connected to the bottom wall inside the worktable 1 away from the material discharge assembly 3.

[0026] The riveting assembly 2 includes a mounting platform 201, a cylinder 202 is fixedly connected to the top of the mounting platform 201, and a hot riveting head 203 is fixedly connected to the output end of the cylinder 202.

[0027] The material discharge assembly 3 includes multiple connecting rods 301. The bottom of the multiple connecting rods 301 is fixedly connected to a material discharge platform 302. The outer wall of the material discharge platform 302 is fixedly connected to a material discharge motor 303. The output end of the material discharge motor 303 is fixedly connected to a threaded rod 304. The outer surface of the threaded rod 304 is threadedly connected to a movable seat 305. The bottom of the movable seat 305 is fixedly connected to a first electric telescopic rod 306. The bottom of the first electric telescopic rod 306 is fixedly connected to a clamping seat 307.

[0028] Multiple second electric telescopic rods 15 are fixedly connected to the bottom of the rotating disk 8, and push plates 16 are fixedly connected to the output ends of the multiple second electric telescopic rods 15. The push plates 16 are set inside the placement base 9.

[0029] A discharge conveyor belt 17 is fixedly connected to one end of the bottom wall of the workbench 1 away from the horizontal camera 14. The discharge end of the discharge conveyor belt 17 passes through the workbench 1 and extends to the outside.

[0030] In this embodiment, by placing the workpiece to be riveted into the placement seat 9, the servo motor 6 is started to drive the rotating shaft 7 to rotate. The rotating shaft 7 drives the rotating disk 8 to rotate, and at the same time, it drives the placement seat 9 to rotate. When the placement seat 9 rotates to the horizontal camera 14, the horizontal camera 14 detects the horizontality of the workpiece to be riveted. When the horizontal camera 14 finds that the workpiece to be riveted is not aligned, it transmits a signal and starts the drive motor 13 to drive the rotating rod 11 to rotate. At the same time, it drives the pressure plate 12 connected to the rotating rod 11 to flip. By flipping the pressure plate 12, it moves above the placement seat 9 to adjust and align the workpiece to be riveted in the placement seat 9, ensuring that each riveted workpiece can be riveted accurately during the processing. This not only improves the processing accuracy but also reduces the scrap rate, thereby improving production efficiency and product quality.

[0031] Example 2

[0032] like Figure 1 - Figure 5 As shown, based on Embodiment 1, a circulating water pump 18 is fixedly connected to the outer wall of the heat sink 4, a cooling water pipe 19 is fixedly connected to the output end of the circulating water pump 18, heat dissipation fins 20 are provided on the outer surface of the cooling water pipe 19, and two cooling fans 21 are provided on the back of the heat sink 4.

[0033] The cooling water pipe 19 is located inside the heat sink 4, below the servo motor 6.

[0034] A temperature sensor 22 is fixedly connected to the top of the mounting bracket 5. The temperature sensor 22 is electrically connected to the circulating water pump 18 and two cooling fans 21.

[0035] In this embodiment, the internal temperature of the heat sink 4 is collected by the temperature sensor 22. When the internal temperature of the heat sink 4 is lower than the set value, the circulating water pump 18 and the cooling fan 21 are turned off. When the internal temperature of the heat sink 4 rises due to the operation of the hot riveting machine, the circulating water pump 18 is started to drive the coolant in the cooling water pipe 19 to circulate, carrying the heat out of the heat sink 4 and dissipating the heat into the air through the heat dissipation fins 20 on the cooling water pipe 19, reducing the accumulation of heat inside the heat sink 4 and ensuring the heat dissipation effect of the device. When the internal temperature of the heat sink 4 is higher than the set value, the two cooling fans 21 are started to assist in heat dissipation and quickly dissipate heat from the heat sink 4, avoiding the internal temperature of the hot riveting machine from becoming too high in a short time, which could damage the internal components and affect the service life of the equipment.

[0036] Working principle: First, power on the hot riveting machine and place the workpiece to be riveted into the placement seat 9. Then, start the servo motor 6 to drive the rotating disk 8 to rotate. During rotation, the horizontal camera 14 detects the workpiece to be riveted and adjusts the position of any misaligned workpieces using the pressure plate 12. After alignment, the workpiece moves to below the riveting assembly 2 as the rotating disk 8 rotates. The cylinder 202 drives the hot riveting head 203 to move downwards and perform hot riveting on the workpiece. After riveting, the workpiece continues to rotate and move to below the discharge assembly 3. The second electric telescopic rod 15 drives the push plate 16 to move upward, causing the push plate 16 to push the riveted workpiece out of the placement seat 9. Then, the first electric telescopic rod 306 drives the clamping seat 307 to move downward and clamp the riveted workpiece. Then, the feeding motor 303 is started to drive the threaded rod 304 to rotate, driving the moving seat 305 to move along the feeding table 302 to the discharge conveyor belt 17. At the same time, the riveted workpiece is moved to the discharge conveyor belt 17, and the riveted workpiece is discharged from the workbench 1 through the discharge conveyor belt 17 for centralized collection.
