Abstract
Description
Technical Field
[0001] This utility model relates to the field of PCB manufacturing technology, and more specifically, to a self-propelled temporary storage machine for PCB boards. Background Technology
[0002] During the manufacturing process of printed circuit boards (PCBs), they typically undergo processes such as ink coating, drying, and baking. PCBs are usually transported one by one through the work stations of these processes using conveyor equipment on the production line to increase production capacity. Since the time required for each PCB process varies, PCBs are prone to congestion on the production line when performing a certain process. To overcome this congestion, PCB temporary storage machines are usually connected in series on production lines with different process speeds.
[0003] In the existing technology, although the above-mentioned equipment can realize the temporary storage function, in the actual production process, printed circuit boards are produced in various sizes according to different needs. When the printed circuit boards are transported on the temporary storage machine, the temporary storage width of the machine cannot be adjusted, which makes it easy for PCB products to enter the gap between the rollers on the temporary storage machine and not be able to pass through. Especially when the PCB board has been cut, the difference in size before and after the cut is large, and both need to be temporarily stored. As a result, when the cut PCB board enters the temporary storage machine again, it is easy to fall into the gap between the rollers on the temporary storage machine, affecting the normal use of the temporary storage machine and the normal operation of the PCB production line.
[0004] Therefore, a self-propelled temporary storage machine for PCB boards is needed to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a self-propelled temporary storage machine for PCB boards to solve the problems mentioned in the background art.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A self-propelled temporary storage machine for PCB boards includes a frame and a worktable located inside it. The worktable is equipped with a conveying component, a storage component, and an adjusting component. The conveying component includes two rows of support plates and a plurality of conveying rollers. The two rows of support plates are fixedly connected to the top surface of the worktable, and a plurality of connecting shafts are provided between the two rows of support plates. The plurality of rollers are sleeved on the connecting shafts. The storage component includes a plurality of support columns, which are alternately arranged with a plurality of connecting shafts at both ends along the length of the connecting shafts. Two opposite support columns are connected by the plurality of support shafts. The plurality of support shafts are arranged in an array and are parallel to the connecting shafts. All the support columns and the plurality of support shafts pass through the worktable. The adjustment assembly includes several drive shafts and several drive components. The drive components are connected to the drive shafts in a transmission manner. The drive shafts are located below the connecting shaft. One end of each drive component is disposed on the drive shaft, and the other end of each drive component is disposed on the conveying roller.
[0007] The technical solution of this utility model is further configured as follows: both sides of the conveying roller are provided with annular grooves, the driving component includes a sleeve and a connecting component, the sleeve is threadedly connected to the driving shaft, the connecting component is fixedly connected to both ends of the sleeve in the length direction, and the other end of the connecting component is located in the annular groove.
[0008] The technical solution of this utility model is further configured such that: the drive shaft includes several threaded segments that are fixedly connected to each other, and the helical directions of adjacent threaded segments are opposite.
[0009] The technical solution of this utility model is further configured as follows: a groove is provided on the outer wall of the connecting shaft along its length direction, and a protrusion located in the groove is fixedly connected to the conveying roller.
[0010] The technical solution of this utility model is further configured as follows: several drive shafts are connected by synchronous toothed belt transmission, and a driver is provided on the worktable. The drive end of the driver is fixedly connected to one of the drive shafts.
[0011] The technical solution of this utility model is further configured as follows: both ends of the connecting shaft pass through the support plate and a magnetic wheel is fixedly connected to the end of the shaft extending out of the support plate; a magnetic wheel is provided below each of the magnetic wheels; the magnetic wheels are connected by a rotating shaft; a driver is provided on the workbench; the driver is connected to the rotating shaft by a transmission belt.
[0012] The technical solution of this utility model is further configured such that: the storage component also includes a connecting plate located below the workbench, and a plurality of the supporting columns are fixedly connected to the top surface of the connecting plate.
[0013] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows: PCBs on conveyor rollers are transported via a conveyor assembly on the worktable. A storage assembly lifts the PCBs from the conveyor rollers for temporary storage. Because a pair of support columns have several support shafts, multiple sets of support shafts can be used to achieve multi-layer storage of PCBs. An adjustment assembly located below the conveyor assembly adjusts the position of the conveyor rollers on the connecting shaft, moving adjacent conveyor rollers closer or further apart, thus adjusting the spacing. This allows PCBs of different sizes to pass through and be temporarily stored, making it particularly suitable for situations where PCBs need to be re-entered into the storage machine after cutting. Since the overall size of the PCB is significantly reduced after cutting, the commonly used spacing between conveyor rollers is unsuitable for transporting the cut PCBs. Therefore, this technical solution adjusts the spacing of the conveyor rollers to adapt to different needs, preventing the cut PCBs from falling into the spacing between the conveyor rollers.

[0016] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model. Example
[0017] like Figures 1 to 6 As shown, this utility model provides a self-propelled temporary storage machine for PCB boards, including a frame 1 and a worktable 2 located inside it. The worktable 2 is provided with a conveying component, a storage component, and an adjustment component. The conveying component includes two rows of support plates 3 and several conveying rollers 4. The two rows of support plates 3 are fixedly connected to the top surface of the worktable 2. Several connecting shafts 5 are provided between the two rows of support plates 3. Several rollers are sleeved on the connecting shafts 5. Both ends of the connecting shafts 5 pass through the support plates 3, and magnetic wheels 17 are fixedly connected to the ends of the connecting shafts 5 that extend out of the support plates 3. Magnetic wheels 18 are provided below the magnetic wheels 17. The magnetic wheels 18 are connected by a rotating shaft 19. The worktable 2 is provided with a driver 20, which is a motor. The driver 20 is connected to the rotating shaft 19 through a transmission belt 21.
[0018] With the above structure, when the temporary storage machine transports PCB boards on the production line, the second driver 20 starts and drives the rotating shaft 19 to rotate through the transmission belt 21, causing several magnetic wheels 18 fixedly connected to the rotating shaft 19 to rotate. The rotating magnetic wheels 18 transmit torque to make the magnetic wheel 17 rotate synchronously, thereby driving the connecting shaft 5 and the conveying roller 4 on the connecting shaft 5 to rotate, thus achieving the effect of transporting PCB boards and enabling the production line to operate stably.
[0019] like Figures 1 to 6 As shown, the storage component includes several support columns 6, which are alternately arranged with several connecting shafts 5 at both ends of the length direction of the connecting shafts 5. Two support columns 6 in opposite positions are connected by several support shafts 7. The several support shafts 7 are arranged in an array and are parallel to the connecting shafts 5. The several support columns 6 and several support shafts 7 all pass through the worktable 2. The storage component also includes a connecting plate 22 located below the worktable 2. The several support columns 6 are all fixedly connected to the top surface of the connecting plate 22. A cylinder (not shown in the figure) is provided in the frame 1 located below the connecting plate 22. The output end of the cylinder is fixedly connected to the bottom surface of the connecting plate 22.
[0020] With the above structure, when the temporary storage machine needs to temporarily store PCB boards, the conveyor roller 4 rotates to move the PCB board, and both ends of the PCB board are positioned on the support shaft 7. Then, the cylinder in the frame 1 is activated, and the output end of the cylinder drives the connecting plate 22 and the support column 6 on the surface of the connecting plate 22 to move, thereby moving the support shaft 7 upward in the frame 1 to lift the PCB board and achieve the temporary storage effect. The number of PCB boards that can be stored can be determined according to the number of support shafts 7 on the support column 6, overcoming the congestion that may occur on the production line.
[0021] like Figures 1 to 8 As shown, the adjustment assembly includes several drive shafts 8 and several drive components. The drive shafts 8 are located below the connecting shaft 5 and include several threaded sections 12 that are fixedly connected to each other. The spiral directions of adjacent threaded sections 12 are opposite. Synchronous pulleys are fixedly connected to each of the drive shafts 8. The synchronous pulleys on adjacent drive shafts 8 are connected by a synchronous toothed belt 15. The worktable 2 is provided with a driver 16, which is a motor. The drive end of the driver 16 is fixedly connected to one of the drive shafts 8. The drive component includes a sleeve 10 and a connector 11. The sleeve 10 is threaded to the drive shaft 8. The connector 11 is fixedly connected to both ends of the sleeve 10 in the length direction. Annular grooves 9 are provided on both sides of the conveying roller 4. The other end of the connector 11 is located in the annular groove 9. A sliding groove 13 is provided on the outer wall of the connecting shaft 5 along its length direction. A protrusion 14 located in the sliding groove 13 is fixedly connected to the conveying roller 4.
[0022] In summary, when the PCB board size changes on the production line, driver 16 can be activated, causing one of the drive shafts 8 to rotate. Since all drive shafts 8 are connected by a synchronous toothed belt 15, all drive shafts 8 can rotate synchronously after driver 16 is activated. The rotated drive shaft 8 causes its surface to move horizontally in relation to the sleeve 10 connected to its thread. Because the sleeve 10 is connected to the conveyor roller 4 through the connector 11, the moving sleeve 10 can drive the conveyor roller 4 to move along the slide 13, thereby adjusting the position of the conveyor roller 4. At the same time, because the helical directions of adjacent threaded sections 12 are opposite, adjacent conveyor rollers 4 will move closer or further away from each other, which can adapt to the requirements of PCB board sizes of different widths and ensure that this temporary storage machine can stably transport PCB boards. The annular groove 9 on the conveyor roller 4 can avoid affecting the rotation of the conveyor roller 4.
[0023] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
