[0002] Currently, when processing PCB boards, factories typically affix identification codes, such as barcodes or QR codes, to facilitate tracking of the PCB board processing process. Then, the PCB boards are sequentially transported to the processing areas of various processing devices via a conveyor mechanism. Due to the variety of PCB board styles, the width of the conveyor mechanism needs to be adjusted when transporting PCB boards of different sizes. However, adjusting the existing conveyor mechanism requires partial disassembly and reassembly of the conveyor mechanism, as well as spacing adjustments, making the operation quite complicated.

Detailed Implementation
[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0022] Example 1: See Figures 1 to 3 A conveying mechanism includes: two parallel and spaced-apart side plates 1, each side plate 1 having at least one belt conveyor mechanism 2 on its inner side, and support blocks 14 connected to the lower ends of each side plate 1, with nut blocks 15 installed on the support blocks 14; it also includes adjusting seats at the front and rear ends, each adjusting seat including vertical blocks 4 arranged left and right, bearing seats 20 installed at the upper end of the vertical blocks 4, a lead screw 30 connected between the two bearing seats 20, the middle part of the lead screw 30 being threadedly connected to the nut block 15, the left end of the lead screw 30 extending out of the left vertical block 4 to form a connecting end, a synchronous transmission mechanism 5 connected between the connecting ends of the two lead screws 30, and the right end of one of the lead screws 30 extending out of the corresponding vertical block 4 and connected to an operating unit 9 for assisting in the rotation of the lead screw 30.
[0023] In this embodiment, a belt conveyor device is provided on the inner side of the two side plates 1. The belt conveyor device includes a belt 21. During operation, the two ends of the PCB board or the carrier carrying the PCB board are respectively attached to the belt 21 of the two side belt conveyors. Under the synchronous conveying of the two side belt conveyors, the PCB board or the carrier is conveyed forward. When the PCB board or the carrier is replaced, the operation unit 9 is rotated, and the operation unit 9 drives the lead screw 30 to rotate. The nut block 15 rotates relative to the lead screw 30, and at the same time, the nut block 15 moves left and right. The nut block 15 drives the support block 14 to move left and right, and the support block 14 drives the side plate 1 to move, thereby adjusting the distance between the two side plates 1. The distance between the two belts 21 is adjusted, thereby achieving the purpose of adjusting the feeding width.
[0024] The entire system can be adjusted without disassembly or installation. Simply rotate the operating unit 9; operation is convenient and simple.
[0025] See Figure 3 A horizontal support plate 19 is connected between the vertical blocks 4 on both sides. A horizontal guide rail 18 is connected to the horizontal support plate 19. A slider 17 is connected to the lower end of the support block 14. The slider 17 is slidably connected to the horizontal guide rail 18.
[0026] Since the support block 14 needs to bear the weight of the side plate 1 and the belt conveyor mechanism 2, if it relies solely on the nut and lead screw 30, the lead screw 30 will bend, or the lead screw 30 will need to be made of a material with high strength. Therefore, in this embodiment, a horizontal support plate 19, a horizontal guide rail 18, and a slider 17 are provided. The weight of the side plate 1 is transferred to the slider 17, the horizontal guide rail 18, and the horizontal support plate 19 through the support plate, thereby preventing the lead screw 30 from bending due to bearing the weight. During operation, the lead screw 30 rotates, causing the nut block 15 to move, and the support block 14 causes the slider 17 to move on the horizontal guide rail 18. In a specific configuration, a base plate 16 is connected to the lower end of the support plate, and the base plate 16 is fixedly connected to the slider 17. The base plate 16 is provided to facilitate connection with the slider 17.
[0027] See Figure 3 One of the vertical blocks 4 is connected to a positioning structure 10 for fixing the lead screw 30. The positioning structure 10 includes a main positioning block 12 connected to the vertical block 4. One end of the main positioning block 12 is connected to the vertical block 4, and the other end of the main positioning block 12 is connected to a main clamping block 11. The main clamping block 11 is connected to a secondary clamping block 13. The main clamping block 11 and the secondary clamping block 13 are respectively provided with semi-concave holes. The two semi-concave holes are spliced together to form a clamping hole that cooperates with the lead screw 30. The main clamping block 11 and the secondary clamping block 13 are respectively connected to connecting holes and connected by bolts or screws.
[0028] To prevent the lead screw 30 from rotating due to vibration during operation, which could cause a change in the distance between the two side plates 1, a positioning mechanism is provided in this embodiment. By rotating bolts and screws, the main clamping block 11 and the auxiliary clamping block 13 loosen their grip on the lead screw 30, preventing rotation. When adjusting the side plates 1, the main clamping block 11 and the auxiliary clamping block 13 are first loosened, and then adjusted. After adjustment, the main clamping block 11 and the auxiliary clamping block 13 are tightly clamped onto the lead screw 30 by rotating bolts and screws.
[0029] See Figure 1 , Figure 3 The operation unit 9 includes a rotating disk 91 connected to the lead screw 30, and a rotating rod 92 connected to the outer side of the rotating disk 91.
[0030] The operation is convenient by setting up a rotating disk 91 and a rotating rod 92; by controlling the rotating rod 92, the rotating disk 91 is driven to rotate, and the rotating disk 91 then drives the lead screw 30 to rotate.
[0031] See Figure 2The synchronous transmission mechanism 5 includes synchronous pulleys 53 connected to two lead screws 30, and a synchronous belt 51 is connected between the two synchronous pulleys 53.
[0032] By connecting the synchronous pulley 53 to the connection end of the two lead screws 30, when the operating unit 9 operates one of the lead screws 30 to rotate, the lead screw 30 drives the other lead screw 30 to rotate synchronously through the synchronous transmission mechanism 5, thereby achieving synchronous rotation of the two lead screws 30 and driving the front and rear ends of the two side plates 1 to move synchronously.
[0033] See Figure 2 The synchronous transmission mechanism 5 also includes a tension adjusting wheel 52, which is connected to an adjusting block 54 via a connecting shaft. The adjusting block 54 is provided with an adjusting groove 55 and is connected to an adjacent support block 14 via a connecting piece.
[0034] The connecting parts can be bolts, screws, etc.; after setting the tension adjusting wheel 52, the tension of the timing belt 51 can be adjusted to facilitate the connection of the two timing wheels 53 through the timing belt 51; during adjustment, the tension adjusting wheel 52 can be adjusted by adjusting the position of the adjusting block 54 connected to the support block 14.
[0035] See Figure 1 , Figure 2 The inner side of the side plate 1 is connected to three belt conveyor mechanisms 2. Each belt conveyor mechanism 2 includes at least two driven pulleys 22, a conveyor motor 23, and a driving pulley 26. The conveyor motor 23 is connected to a fixing plate 24, which is fixed to the side plate 1. The conveyor motor 23 drives the driving pulley 26, which is connected to the two driven pulleys 22 via a belt 21.
[0036] Each side plate 1 is connected to three belt conveyor mechanisms 2, making the conveying process three-segmented. The front segment can be used for loading, the middle segment for conveying and processing, and the rear segment for unloading. The three segments are independent. When the PCB is being processed, the PCB is located in the middle segment, and the conveying of the front and rear segments continues without interference, which can relatively improve the processing efficiency.
[0037] See Figure 2 The belt conveyor mechanism 2 also includes two directional adjustment wheels 25, which are located above the conveyor motor 23.
[0038] By setting two directional adjustment wheels 25, the direction of the belt 21 is changed, the connection area between the belt 21 and the drive pulley 26 is increased, and the belt 21 is prevented from slipping.
[0039] See Figure 1 , Figure 2A connecting plate 3 is connected between the rear ends of the two side plates 1. A stop motor 6 is connected to the connecting plate 3. A blocking plate 7 is connected to the upper end of the stop motor 6. A sensor 8 is connected to the rear end of one of the side plates 1.
[0040] When the PCB board or carrier arrives at the rear conveyor mechanism, it is detected by sensor 8, and the stop motor 6 drives the blocking part to extend and block the movement of the PCB board or carrier; after the PCB board or carrier is removed, the stop motor 6 resets. This prevents the PCB board or carrier from detaching from the conveyor mechanism.
[0041] Example 2: A patching machine, including the above-mentioned conveying mechanism.
