Abstract
Description
Technical Field
[0001] This utility model relates to the field of PCBA processing, and more specifically, to a conveying mechanism for PCBA processing. Background Technology
[0002] PCBA is short for Printed Circuit Board Assembly. It refers to the entire process of a bare PCB board undergoing SMT (Surface Mount Technology) component mounting or DIP (Dual In-line Package) insertion. Printed circuit boards, also known as printed circuit boards or printed circuit boards, are important electronic components. They support electronic components and provide the connection for electronic component circuits. Because they are made using electronic printing technology, they are called "printed" circuit boards. During PCBA processing, they are usually transported on a conveyor belt to facilitate individual processing and testing.
[0003] In existing PCBA processing, the PCBA is transported on a conveyor belt. Due to the vibration of the conveyor mechanism itself and the light weight of the PCBA, it is easy for the PCBA to deviate and fall off during the transmission process. In addition, after long-term use, dust and debris will adhere to the outer surface of the conveyor belt, which will contaminate the surface of the PCBA. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a conveying mechanism for PCBA processing.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a conveying mechanism for PCBA processing, comprising a first transmission roller and a second transmission roller arranged parallel to each other at the same height, a transmission belt connecting the outer sides of the first transmission roller and the second transmission roller, and support frames connected to both ends of the first transmission roller and the second transmission roller, wherein a motor for driving the first transmission roller to rotate is installed on the top outer wall of one of the support frames, and a control switch box is installed on the bottom outer wall of the support frame, a crossbeam is fixedly connected horizontally between the tops of the two support frames on the same side, a side plate is fixedly connected vertically to the top of the crossbeam located outside the transmission belt, a top plate is fixedly connected to the top inner wall of the side plate near the upper position of the transmission belt, and a connecting plate is fixedly connected to the bottom inner wall of the side plate near the lower position of the transmission belt, a plurality of rollers are movably connected between the top of the connecting plate and the bottom of the rollers, and a cleaning mechanism is provided on the inner wall of the support frame near the bottom position of the transmission belt.
[0006] As a further improvement to the technical solution of this utility model, the motor is fixedly installed on the top outer wall of the support frame by bolts, and the connection between the two ends of the crossbeam and the top of the support frame is welded.
[0007] As a further improvement to the technical solution of this utility model, the top plate and the connecting plate are arranged in parallel, and the ends of the top plate and the connecting plate are fixed to the inner sidewall of the side plate by screws or welding.
[0008] As a further improvement to the technical solution of this utility model, bearing seats are installed at the top of the connecting plate and the bottom of the top plate at the positions corresponding to the two ends of the central shaft of the roller.
[0009] As a further improvement to the technical solution of this utility model, the cleaning mechanism includes a support plate fixedly connected to the bottom outer wall of the support frame below the transmission belt. A placement frame is fixedly connected to one end of the support plate. A dust collection box is installed on the inner side of the placement frame. A fixed shell is fixedly connected to the top of the support plate outside the transmission belt. A slide is provided at the bottom of the fixed shell. An inclined fixed frame is fixedly connected to the top outer wall of the slide. A cleaning brush roller is installed on the top inner side of the fixed frame near the bottom of the transmission belt.

[0012] The beneficial effects of this utility model are:
[0013] 1. By setting side plates on both sides of the top of the transmission belt, the inner side wall of the side plates is connected to the top plate and the connecting plate, and several rollers are movably connected between the top plate and the connecting plate. When the PCBA board is conveyed on the transmission belt, it is convenient to maintain a limit and guide the PCBA board on the transmission belt, improve the stability of the PCBA board when it is conveyed on the transmission belt, and prevent the PCBA board from falling due to the vibration of the conveying mechanism itself.
[0014] 2. By setting up a cleaning mechanism, during use, the transmission belt passes through the top inner side of the fixed shell.

[0022] As attached Figure 1 As shown, the motor 5 is fixedly installed on the top outer wall of the support frame 4 by bolts, which facilitates the installation and fixation of the motor 5, thereby facilitating the synchronous rotation of the first transmission roller 1 and the second transmission roller 2, and thus maintaining the stable transmission of the transmission belt 3. The connection between the two ends of the crossbeam 7 and the top of the support frame 4 is welded, which facilitates the connection and fixation of the crossbeam 7.
[0023] As attached Figure 2-3 As shown, the top plate 9 and the connecting plate 10 are arranged in parallel, and the ends of the top plate 9 and the connecting plate 10 are fixed to the inner side wall of the side plate 8 by screws or welding, which facilitates the connection and fixing of the top plate 9 and the connecting plate 10, and thus facilitates the installation of the roller 11.
[0024] As attached Figure 2-3 As shown, bearing seats are installed at the top of the connecting plate 10 and the bottom of the top plate 9 at the two ends of the central shaft of the roller 11, so that the roller 11 can maintain a rotating connection between the top of the connecting plate 10 and the bottom of the top plate 9. This facilitates the PCBA board to maintain a limiting and guiding function during transmission on the transmission belt 3, improves the stability of the PCBA board during transmission on the transmission belt 3, and makes it less prone to deviation.

[0026] Working principle: This utility model designs a conveying mechanism for PCBA processing, the specific structure of which is shown in the attached instruction manual. Figure 1-4 As shown, in use, the control motor 5 drives the transmission belt 3 to transport the PCBA boards to be processed one by one to one end of the transmission belt 3. The boards are then conveyed to the processing position. Side plates 8 are provided on both sides of the top of the transmission belt 3. The inner walls of the side plates 8 are connected to a top plate 9 and a connecting plate 10. Several rollers 11 are movably connected between the top plate 9 and the connecting plate 10. During the transmission and conveying of the PCBA boards on the transmission belt 3, these rollers provide a limiting and guiding function, improving the efficiency of the PCBA boards during transmission. Stability is ensured, preventing PCBA boards from shifting and falling due to vibrations of the conveyor mechanism itself. Furthermore, a cleaning mechanism is installed at the bottom of the conveyor belt 3. During use, the conveyor belt 3 passes through the top inner side of the fixed housing 15. The starting motor 19 drives the cleaning brush roller 18 to rotate and clean the outer surface of the conveyor belt 3. Dust or debris falling during the cleaning process falls onto the slide table 16 and gradually slides into the dust collection box 14 for collection. This facilitates the cleaning of dust and debris adhering to the outer surface of the conveyor belt 3 during use, reducing contamination of the PCBA board surface.
