[0002] In circuit board manufacturing companies, the production process of circuit boards is inseparable from the board conveyor. The board conveyor is a device specifically designed for the transport of circuit boards. At present, the board conveyors on the market require the producer to adjust the spacing between the two board conveyor belts according to the width of the board. Usually, a hand crank is used for adjustment. When adjusting, the board to be transported is held to confirm the size of the spacing. The adjustment process is relatively troublesome and time-consuming. Utility Model Content

A guide rail is provided between the first board material conveyor belt and the second board material conveyor belt. The first board material conveyor belt is fixed on the base, and the second board material conveyor belt is slidably connected to the guide rail. A driving device for driving the second board material conveyor belt to slide is provided on the base. A distance measuring device is provided on the first board material conveyor belt and the second board material conveyor belt. The driving device, the infrared width measuring device, and the distance measuring device are electrically connected to a controller.

[0005] In one or more embodiments, the driving device includes a drive motor, a screw, and a screw sleeve. The drive motor is mounted on a base, and the screw sleeve is fixed to the second sheet conveyor belt and screwed to the screw.

[0006] In one or more embodiments, the driving device is provided with two or more screws, which are spaced apart along the length of the second sheet conveyor belt. Screw sleeves are provided on the second sheet conveyor belt at locations corresponding to the screws and connected to them. The screws are connected to each other by a synchronous belt.

[0007] In one or more embodiments, the drive motor is equipped with a gearbox.

[0008] In one or more embodiments, the ranging device includes an infrared transmitter and an infrared receiver, the infrared transmitter being disposed on a second sheet conveyor belt and the infrared receiver being disposed on a first sheet conveyor belt.

[0009] In one or more embodiments, the infrared width measuring device includes an infrared receiving base plate and an infrared light curtain transmitter, with the infrared light curtain transmitter positioned above the infrared receiving base plate.

[0010] Compared with the prior art, the advantages of this utility model are: the sheet metal conveyor can measure the width of the sheet metal in advance through an infrared width measuring device, adjust the distance between the first sheet metal conveyor belt and the second sheet metal conveyor belt through a drive device, and confirm the distance through a distance measuring device, thereby realizing automated distance adjustment and having the advantage of high distance adjustment efficiency. Attached Figure Description

[0011] Figure 1 This is a schematic diagram of the sheet metal conveyor in this embodiment. Detailed Implementation

[0012] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0013] Please refer to Figure 1 This application provides a PCB conveyor with adaptive board width distance, comprising a first board conveyor belt 2, a second board conveyor belt 3, and an infrared width measuring device mounted on a base 1. A guide rail 4 is provided between the first board conveyor belt 2 and the second board conveyor belt 3. The first board conveyor belt is fixed on the base 1, and the second board conveyor belt is slidably connected to the guide rail. A drive device is provided on the base to drive the second board conveyor belt to slide. A distance measuring device is provided on the first and second board conveyor belts. The drive device, the infrared width measuring device, and the distance measuring device are electrically connected to a controller 5. In use, the user first places the board to be conveyed on the infrared width measuring device to measure its width. The infrared width measuring device feeds back the measured width to the controller. The distance measuring device feeds back the current distance between the first and second board conveyor belts to the controller. The controller controls the drive device to adjust the distance between the second and first board conveyor belts based on the width data from the infrared width measuring device and the distance measuring device, thereby adapting to the width of the board and facilitating board conveying.

[0014] Specifically, the driving device includes a drive motor 6, a screw 7, and a screw sleeve 8. The drive motor is mounted on the base 1, and the screw sleeve 8 is fixed to the second sheet metal conveyor belt and screwed to the screw. The drive motor drives the screw to rotate, causing the second sheet metal conveyor belt to slide along the guide rail, thereby achieving the adjustment of the distance between the first and second sheet metal conveyor belts. To improve the output torque and stabilize the output of the drive motor, the drive motor is equipped with a reduction gearbox 10.

[0015] The drive device is provided with two or more screws 7, which are distributed at intervals along the length of the second sheet material conveyor belt. The second sheet material conveyor belt is provided with a screw sleeve connected to the screw at the corresponding location. The screws are connected to each other by a synchronous belt 9. The first and second sheet material conveyor belts, which are relatively long, are usually provided with multiple guide rails. Therefore, the drive device is provided with two or more screws to improve the uniformity of the force when the second sheet material conveyor belt slides and ensure the smoothness of the sliding.

[0016] Specifically, the ranging device in this embodiment includes an infrared transmitter 11 and an infrared receiver 12. The infrared transmitter is located on the second sheet conveyor belt, and the infrared receiver is located on the first sheet conveyor belt.

[0017] The infrared width measuring device includes an infrared receiving base plate 13 and an infrared light curtain emitter 14. The infrared light curtain emitter is located above the infrared receiving base plate. When the sheet is placed on the infrared receiving base plate, the light emitted by the infrared light curtain emitter onto the sheet will be blocked by the sheet. As a result, the infrared receiving base plate cannot receive the infrared light from the area blocked by the sheet, thereby obtaining the width data of the sheet.

[0018] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. Any equivalent modifications or changes made by those skilled in the art based on the content disclosed in the present utility model should be included in the protection scope recorded in the claims.
