[0002] In the automotive manufacturing industry, the spraying of auto parts is one of the key links in the production process, and its quality and efficiency directly affect the appearance quality and production efficiency of the whole vehicle. With the development of the automotive industry, the requirements for the spraying accuracy and efficiency of auto parts are increasing day by day.

[0003] As an important device for realizing automatic spraying, the automatic spraying conveyor line realizes the automatic spraying operation of auto parts from the on-line to the off-line process. However, in the process of automatic spraying, there are still some deficiencies in ensuring the precise positioning of parts at the spraying station. The positioning accuracy of some positioning devices is limited. In addition, after long-term operation, some positioning devices are prone to problems such as inaccurate positioning or frequent failures due to wear and vibration. Therefore, an automatic spraying conveyor line and a positioning device are proposed. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies in the prior art that the positioning accuracy of some positioning devices is limited, and after long-term operation, some positioning devices are prone to problems such as inaccurate positioning or frequent failures due to wear and vibration, and to propose an automatic spraying conveyor line and a positioning device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] An automatic spraying conveyor line includes a first frame and a second frame. The first frame and the second frame are arranged in parallel. The tops of the first frame and the second frame are fixedly connected with an installation box. The inner walls of both sides of the installation box are respectively rotatably connected with a first rotating shaft and a second rotating shaft. Two transmission belts are arranged on the circumferential outer walls of the first rotating shaft and the second rotating shaft through belt pulleys. A plurality of hooks are arranged on the top of the transmission belt. Support plates are fixedly connected between the inner walls of both sides of the first frame and the second frame.

[0007] In a possible design, a motor is arranged on the top of the support plate on one side of the first frame, and the output shaft of the motor is fixedly connected with a first belt pulley.

[0008] In a possible design, a first transmission groove and a second transmission groove are respectively formed on the circumferential outer wall of the first rotating shaft.

[0009] In a possible design, the first belt pulley and the circumferential outer wall of the first transmission groove are provided with the same first belt in a transmission manner. The first belt respectively penetrates through the bottom of the installation box and the top of the first frame.

[0010] A positioning device is used in cooperation with an automated spraying conveyor line described in any one of the above. It includes a positioning mechanism. The positioning mechanism is arranged on the top of the installation box. The positioning mechanism is located between two conveyor belts. The positioning mechanism includes two fixing frames, two first mounting plates and a second mounting plate. The two fixing frames, the two first mounting plates and the second mounting plate are all fixedly connected to the top of the installation box. A positioning card slot for restricting the position of the hook is fixedly connected to the top of the fixing frame. One side of the first mounting plate is rotatably connected to a second rotating pin. The second rotating pin rotatably penetrates the first mounting plate. One end of the second rotating pin is fixedly connected to a strip-shaped rotating block. The other end of the second rotating pin is fixedly connected to a circular rotating block. A first rotating pin is fixedly connected to the top of the strip-shaped rotating block away from the first mounting plate. The circumferential outer walls of the two first rotating pins are rotatably connected to the same first connecting rod. A plurality of lifting card slots for lifting the hook are fixedly connected to the top of the first connecting rod. A third rotating pin is eccentrically arranged on the side of the circular rotating block away from the first mounting plate. The circumferential outer walls of the two third rotating pins are rotatably connected to the same second connecting rod. A fifth rotating pin is fixedly connected to the side of the second mounting plate close to the first mounting plate. A second pulley is rotatably connected to the circumferential outer wall of the fifth rotating pin. A fourth rotating pin is eccentrically arranged on the side of the second pulley close to the first mounting plate. One end of the fourth rotating pin is rotatably connected to the center of the side of the second connecting rod close to the second mounting plate.

[0011] In a possible design, the same second belt is drivingly arranged on the circumferential outer walls of the second pulley and the second transmission groove.

[0012] In this application, when people need to spray automotive parts, first hang the automotive parts on the hook, then place the hook on the conveyor belt, and then start the motor. The motor drives the first rotating shaft to rotate through the transmission of the first pulley, the first belt and the first transmission groove. Then the first rotating shaft drives the conveyor belt, and then through the hook, the automotive parts are conveyed to one side of the positioning mechanism for waiting to be sprayed. At this time, the first rotating shaft drives the second pulley to rotate along the fifth rotating pin through the transmission of the second transmission groove and the second belt. Then the second pulley drives the circular rotating block to rotate along the second rotating pin through the fourth rotating pin, the second connecting rod and the third rotating pin. Furthermore, the strip-shaped rotating block is driven to rotate along the second rotating pin through the second rotating pin. Then the strip-shaped rotating block drives the first connecting rod to move in an ellipse through the first rotating pin. At this time, the lifting card slot on the first connecting rod will send the automotive parts into the designated spraying position by lifting the hook and fix them through the positioning card slot. Then through the next lift of the lifting card slot, the automotive parts enter the next spraying point. This cycle continues until the automotive parts are sprayed. Then the lifting card slot sends the automotive parts out of the spraying area and conveys them to the next process through the conveyor belt.

[0013] In the present utility model, for the automated spraying conveyor line and positioning device, by driving the rotation of the first belt pulley, the first belt and the first rotating shaft through a motor, the continuous operation of the conveyor belt is effectively driven, realizing the efficient transmission of automotive parts from the upstream to the spraying area. At the same time, the lifting card slot in the positioning mechanism cooperates with the positioning card slot to accurately position the parts at the spraying points, improving the efficiency and accuracy of the spraying operation;

[0014] In the present utility model, for the automated spraying conveyor line and positioning device, through the setting of the positioning mechanism, by the linkage of the second belt pulley, the second connecting rod, the circular rotating block and the strip-shaped rotating block, the elliptical trajectory movement of the lifting card slot is realized. This design not only ensures the stable positioning of the parts during the spraying process, but also improves the positioning accuracy through the precise control of mechanical transmission, avoiding errors caused by manual operation or traditional positioning methods;

[0015] In the present utility model, for the automated spraying conveyor line and positioning device, by adjusting the quantity and position of the lifting card slots according to actual requirements to adapt to automotive parts of different sizes and shapes, this self-adaptive design enables the device to perform excellently in various spraying operation scenarios, improving the versatility and practicality of the equipment;
