Technical Field

Background technique

A pot is a cooking utensil. Traditional pots are usually made by hammering. However, with the improvement of technology, pots are usually made of stainless steel and other materials under existing technology. The raw materials are pressed through molds. However, the production process not only requires pressing the raw materials, but also requires a series of processing such as hinged handles on the pot. During each processing, the transportation of the pot in various production equipment is inconvenient. Conveyor belts or manual transfer are usually used. It is difficult to accurately position the pot with a conveyor belt. Manual transportation is costly and inefficient.

The present application is further described in detail below through specific embodiments in conjunction with the accompanying drawings.

A robot production line for cookware, as shown in FIG1, includes a feeding mechanism 1, a forming mechanism 2, a sewing mechanism 3, a punching mechanism 4, a marking mechanism 5, a handle riveting mechanism 6, a coding mechanism 7, a boxing mechanism 8, and a transporting mechanical arm 9. The transporting mechanical arm 9 is used to carry workpieces between the various mechanisms. In specific implementation, the feeding mechanism 1 is provided with two stacking racks for stacking wafers. The feeding mechanism 1 is used to store wafers, and the wafers can be stored on the feeding mechanism 1 before processing.

As shown in FIG1 , the feeding mechanism 1 is provided with a double sheet detection assembly 11 for detecting whether two wafers are stuck together. The double sheet detection assembly 11 includes a double sheet detection sensor 111 and a double sheet storage box 112. When the double sheet detection sensor 111 detects that the wafers are stuck together, the transport robot arm 9 clamps the stuck wafers into the double sheet storage box 112. In specific implementation, the double sheet detection sensor 111 includes an electromagnetic coil double sheet sensor and an ultrasonic electromagnetic coil double sheet sensor. The electromagnetic coil double sheet sensor sends a high-frequency electromagnetic field and detects eddy currents generated by metal materials in a receiving coil. Since the magnetic permeability of the double sheet area is different from that of the surrounding area, different eddy currents are caused in the sensor coil. Therefore, it is possible to determine whether there are double sheets by measuring the voltage value. The ultrasonic sensing technology sends ultrasonic signals and measures the reflection time. Since the ultrasonic reflection time of the double sheet area is different, it is possible to determine whether there are double sheets by comparing the measurement time.

In specific implementation, the visual punching machine uses a camera to locate the workpiece for the first drilling, and the hydraulic punching machine can drill a second hole in the workpiece after alignment.

As shown in Fig. 1 and Fig. 4, the handle riveting mechanism 6 is used to rivet the handle on the hole of the workpiece. The handle riveting mechanism 6 includes a hydraulic riveting machine 61. The hydraulic riveting machine 61 includes two hydraulic cylinders 611. The two hydraulic cylinders 611 are respectively aligned with the two holes of the workpiece and used to squeeze the handle and the workpiece. The hydraulic riveting machine 61 is also fixed with a riveting plate 64. The riveting plate 64 is set corresponding to the hole of the workpiece.

At the same time, the product code is printed on the color box through the coding mechanism 7. Finally, the product is packed into the color box by the boxing mechanism 8 to complete the production.

Embodiment 2

As shown in FIG5 , the main difference between the second embodiment and the first embodiment is that the hydraulic riveting machine 61 is also fixedly provided with a rotating motor 62, and a limit clamp 63 is fixedly provided on the rotating shaft of the rotating motor 62.

The hydraulic riveting machine 61 is also provided with an infrared sensor 63, and the infrared sensor 63 is used to illuminate the hole and monitor the hole through distance data. During specific implementation, the infrared sensor 63 performs detection. When the infrared light cannot pass through the hole, it proves that the hole is not aligned. When it cannot pass through the hole after rotating one circle, it proves that the limit block 631 blocks the hole. At this time, the workpiece needs to be removed and readjusted. When the infrared light passes through the hole normally, it indicates that the hole is aligned and can be riveted. At this time, the hydraulic cylinder 611 squeezes the rivet on the handle, and the riveting can be completed under the support of the hinged plate.

Working principle: The basic working principle is the same as that of the first embodiment, but during riveting, the workpiece is positioned by rotating the motor 62 and the limit claw 63, and the hole position is detected by the infrared sensor 63 to further improve the processing accuracy.

The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
