Description

Technical Field

[0001] This utility model relates to the technical field of conveying devices, and in particular to a synchronous conveying structure for a conveying track. Background Technology

[0002] In existing transmission equipment, the conveyor track typically consists of a fixed track and a movable track, each equipped with a conveyor motor. Circuit boards are transported via a conveyor belt. However, the existing design has the following problems: too many structural components are used, occupying a large space and hindering the addition of functions within a limited space, especially in high-precision equipment such as circuit board fabrication, where space is particularly important; secondly, the two motors are driven independently, resulting in poor conveyor synchronization. Installing the motor on the movable track and running the motor power cable requires the addition of a drag chain, increasing the possibility of circuit failure and resulting in a higher failure rate.

[0003] Therefore, there is an urgent need for a transmission device with optimized structure, good synchronization, and low cost to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a synchronous transmission structure for a transmission track to solve the problems mentioned in the background art.

[0005] The technical problem solved by this utility model is achieved through the following technical solution:

[0006] A synchronous conveying structure for a conveyor track includes a fixed side guide rail and a movable side guide rail. Both the fixed side guide rail and the movable side guide rail are provided with mounting cavities. An elongated protrusion is provided on the side wall of the mounting cavity. A conveyor pulley is rotatably mounted in a recessed area on one side of the mounting cavity. Guide pulleys are rotatably mounted on the side wall of the mounting cavity at the left and right ends of the elongated protrusion, respectively. A conveyor belt is connected between the conveyor pulley and the guide pulleys, and the conveyor belt passes over the upper end face of the elongated protrusion.

[0007] Preferably, tension adjustment pulleys are rotatably mounted on the sidewall of the mounting cavity at the upper side of the conveyor belt pulley on the left and right sides respectively, and the conveyor belt passes around the tension adjustment pulleys.

[0008] Preferably, a servo motor is fixedly installed on the fixed side guide rail, and a spline shaft is fixedly connected to the output end of the servo motor. The spline shaft is connected to the conveyor belt pulley.

[0009] Preferably, the tension adjustment pulley is installed on the mounting cavity through a strip hole, and the tension of the conveyor belt is adjusted by adjusting the distance between the two tension adjustment pulleys.

[0010] Preferably, the mounting cavity sidewall is provided with an annular protrusion, and the conveyor pulley is mounted on the annular protrusion.

[0011] The advantages and positive effects of this utility model are:

[0012] This invention achieves synchronous movement of the fixed and movable tracks through a single power source, ensuring that the circuit board is smoothly transported to the working area of ​​the equipment via the conveyor belt. This effectively avoids the problem of poor synchronization, occupies less overall space, and eliminates the need for additional cable chains compared to traditional transmission methods, effectively reducing the circuit failure rate. It also makes it very convenient to adjust the tension of the conveyor belt to prevent slippage or excessive wear, extending the service life of the transmission components and reducing maintenance costs.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances. The embodiments of this invention are further described in detail below with reference to the accompanying drawings:

[0022] Please see Figure 1-3 This utility model provides an embodiment of a synchronous conveying structure for a conveying track, comprising a base plate 10, a support base 11, fixed side guide rails 12, and movable side guide rails 13. The fixed side guide rails 12 serve as fixed ends on both sides, while the two movable side guide rails 13 in the middle serve as movable ends, forming a conveying group in pairs. A servo motor 14 is fixedly mounted on the fixed side guide rails 12, and the output end of the servo motor 14 is fixedly connected to a splined shaft 15. Both the fixed side guide rails 12 and the movable side guide rails 13 are provided with mounting cavities 16, and elongated protrusions 17 are provided on the side walls of the mounting cavities 16. A conveyor pulley 18 is rotatably mounted in the recessed area on one side of the mounting cavity 16. The spline shaft 15 passes through the movable side guide rail 13 and connects to the conveyor pulley 18 in the fixed side guide rail 12. Guide pulleys 19 are rotatably mounted on the side wall of the mounting cavity 16 at the left and right ends of the elongated protrusion 17. A conveyor belt is connected between the conveyor pulley 18 and the guide pulley 19. The conveyor belt passes around the upper end face of the elongated protrusion 17, so that the two ends of the circuit board abut against the conveyor belts on the fixed side guide rail 12 and the movable side guide rail 13 respectively, driving the servo motor 14 to achieve synchronous transmission.

[0023] It should be noted that, in this embodiment, tension adjustment pulleys are rotatably mounted on the side wall of the mounting cavity 16 on the left and right sides above the conveyor belt pulley 18, respectively. The conveyor belt passes around the tension adjustment pulleys, and the tension adjustment pulleys are mounted on the mounting cavity 16 through strip holes. Adjusting the distance between the two tension adjustment pulleys achieves the adjustment of the tension of the conveyor belt.

[0024] It should also be noted that an annular protrusion is provided on the side wall of the mounting cavity 16, and the conveyor pulley 18 is mounted on the annular protrusion to ensure the transmission of the conveyor pulley 18.

[0025] In practice, the circuit board is first placed on the conveyor belts of the fixed-side guide rail 12 and the movable-side guide rail 13 at the track entrance using a robotic arm or board loading machine. The two sides of the circuit board are supported by the conveyor belts of the two guide rails. Once the operator presses the start button or a sensor detects the board is in place, a signal is sent. The servo motor 14 on the fixed-side guide rail 12 starts, and its output shaft begins to rotate. The torque output by the motor is synchronously transmitted to the conveyor pulleys 18 in all guide rails via the splined shaft 15. The spline connection ensures that even after the movable-side guide rail 13 has moved to accommodate the board width, the power can still be transmitted without loss, and the conveyor pulleys 18 in each mounting cavity 16 begin to rotate. The conveyor belt pulley 18 drives the guide pulley 19 via a closed-loop conveyor belt, initiating the operation of the entire conveyor belt. The conveyor belt adheres closely to the upper surface of the elongated protrusion 17, providing a solid and flat support and driving surface for the PCB board edge. The rotating conveyor belt, through friction with the PCB board edge, drives the PCB board smoothly forward along the track. Since all the conveyor belt pulleys 18 on the guide rails are driven by the same splined shaft 15, all conveyor belts on the fixed and moving sides operate completely synchronously at absolutely consistent speeds. This completely avoids problems such as PCB board jamming, offset, rotation, or edge wear that may occur due to slight differences in transmission speed between the two sides. During transmission, the PCB board is always clamped between the guide rails on both sides, preventing lateral swaying. The close fit design between the conveyor belt and the elongated protrusion 17 prevents the conveyor belt from denting or shaking under load and during driving, ensuring the stability of the transmission height.

[0026] It should be emphasized that the embodiments described in this utility model are illustrative rather than limiting. Therefore, this utility model is not limited to the embodiments described in the specific implementation. Any other implementation methods derived by those skilled in the art based on the technical solutions of this utility model are also within the scope of protection of this utility model.
