Description

Technical Field

[0001] This utility model relates to the field of PCB board cleaning technology, and in particular to a double-sided non-contact cleaning device for PCB boards. Background Technology

[0002] As a core component of electronic devices, PCB boards are widely used in communications, automotive electronics, and consumer electronics. The cleanliness of their surfaces directly affects the soldering reliability of electronic components, circuit conductivity, and the overall operational stability of the equipment. With the increasing precision and density of electronic devices, the requirements for controlling foreign matter (such as dust, electrostatically adsorbed particles, and residual solder slag) on ​​PCB surfaces are becoming increasingly stringent. Efficient and non-destructive cleaning processes have become a crucial step in the electronic manufacturing process.

[0003] Currently, PCB board cleaning mainly employs manual wiping or single-equipment cleaning methods. Manual cleaning requires operators to hold cleaning tools and wipe both sides of the board, which is not only labor-intensive and inefficient, but also prone to causing damage to the PCB board edges and scratches due to improper force control during manual contact. Furthermore, it fails to completely remove tiny foreign objects attracted by electrostatic discharge, resulting in inconsistent cleaning performance. To address these technical problems, this application proposes a non-contact double-sided PCB board cleaning device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a double-sided non-contact cleaning device for PCB boards. Through motor drive, multiple rotating rods are rotated in tandem, which can stably clamp and transport the PCB board, effectively avoiding jamming or surface scratches on the PCB board, improving the cleaning efficiency of the PCB board, and also avoiding damage to the PCB board that may be caused by manual cleaning.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A double-sided non-contact cleaning device for PCB boards includes a conveying mechanism symmetrically arranged in the middle of a mounting frame for conveying PCB boards. The rear end of the mounting frame is connected to a baffle via an air duct, and an air hood is fixedly connected inside the baffle. The air hood is connected to the air duct, and a guide plate is fixedly connected to the bottom of the air hood. The guide plate is rolled outward, and the guide plates on the left and right sides are mirror images of each other. A transmission mechanism is provided at the rear end of the baffle, and the transmission component is connected to the conveying mechanism to provide power to the conveying mechanism.

[0007] Furthermore, the conveying mechanism includes multiple pairs of rotating rods, with rollers fixedly connected to the outer wall of each rotating rod, and the front and rear ends of the rotating rods connected to the transmission mechanism.

[0008] Furthermore, the transmission mechanism includes a drive gear located in the middle of the rear end of the baffle, and the drive gear is driven by a motor. Both ends of the drive gear are meshed with driven gears, and the driven gears are connected to the rotating rod. A first synchronous pulley is fixedly connected to the side of the driven gear away from the baffle, and the first synchronous pulley is connected to a transmission pulley via a synchronous belt. The transmission pulley is connected to another transmission pulley via a synchronous belt, and the transmission pulley is connected to a second synchronous pulley via a belt. The second synchronous pulley is connected to the rotating rod.

[0009] Furthermore, the transmission wheel includes two fixedly connected synchronous pulleys, and the transmission wheel is connected to the rotating rod. One of the synchronous pulleys in the upper transmission wheel is connected to synchronous pulley one via a synchronous belt, and the other synchronous pulley is connected to one of the synchronous pulleys in the lower transmission wheel via a synchronous belt. The other synchronous pulley in the lower transmission wheel is connected to synchronous pulley two via a synchronous belt.

[0010] Furthermore, the driving end of the motor is fixedly connected to the drive gear, and the non-driving end of the motor is connected to the mounting bracket.

[0011] Furthermore, the outer wall of the duct is connected to the top of the baffle by bolts, and the duct passes through the baffle.

[0012] Furthermore, both ends of the rotating rod are fitted with rotating shafts, which are connected to the mounting bracket.

[0013] Furthermore, the outer wall of the mounting bracket is bolted to a shell plate, and an alarm light is installed at the top of the shell plate.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, multiple rotating rods are driven by a motor to rotate in coordination, which can stably clamp and transport the PCB board, effectively avoid the problem of jamming or surface scratching of the PCB board, improve the cleaning efficiency of the PCB board, and also avoid the damage to the PCB board that may be caused by manual cleaning.

[0016] 2. In this utility model, by combining ion air cleaning with dust collection, the ion fan blows ion air onto the PCB board through the air pipe, blowing up foreign objects on both sides of the board. At the same time, the dust collection device sucks up the blown foreign objects from the air hood guide plate end through the air pipe, avoiding the foreign objects from falling back down. Double-sided synchronous cleaning can be completed without disassembling the PCB board, which not only ensures the comprehensiveness and thoroughness of cleaning, but also simplifies the cleaning process and effectively improves the cleanliness of the PCB board surface.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1-3 This utility model provides an embodiment of a double-sided non-contact cleaning device for PCB boards, including a conveying mechanism symmetrically arranged in the middle of a mounting frame 1 for conveying PCB boards. The rear end of the mounting frame 1 is connected to a baffle 5 via an air duct 7. Multiple ion air bars are also provided inside the baffle 5, which are connected to an ion fan via air pipes. The air outlets of the ion air bars face the location of the PCB board, and the ion air bars can blow up foreign objects on the PCB board. The other end of the air duct 7 is connected to a dust collection device, and a hood 14 is fixedly connected inside the baffle 5. The hood 14 is connected to the air duct 7, and the dust collection device can draw in air from the end of the hood 14 where the guide plate 15 is located, thereby cleaning the surface of the PCB board. The bottom of the hood 14 is fixedly connected to the guide plate 15, and the guide plate 15 is rolled outward. The guide plates 15 on the left and right sides are mirror images of each other. A transmission mechanism is provided at the rear end of the baffle 5, and the transmission component is connected to the conveying mechanism to provide power to the conveying mechanism.

[0026] Reference Figure 3-5 The conveying mechanism includes multiple pairs of rotating rods 4. The distance between the upper rotating rod 4 and the lower rotating rod 4 can be customized according to user requirements. Rollers are fixedly connected to the outer wall of the rotating rod 4. By rotating the rotating rod 4, the rotating rod 4 can rotate with the multiple rollers on its outer wall, thereby conveying the PCB board. The front and rear ends of the rotating rod 4 are connected to the transmission mechanism. The transmission mechanism includes a drive gear 13 located in the middle of the rear end of the baffle 5, and the drive gear 13 is driven by a motor 6. Both ends of the drive gear 13 are meshed with driven gears 9. The motor 6 can drive the drive gear 13 to rotate, and the drive gear 13 can drive the two driven gears 9 meshing with it to rotate. The driven gears 9 are connected to the rotating rod 4. A synchronous pulley 8 is fixedly connected to the side of the driven gear 9 away from the baffle 5. The rotation of the driven gear 9 can drive the synchronous pulley 8 fixed with it to rotate, so that the synchronous pulley 8 drives the transmission wheel 10 to rotate through the synchronous belt. The synchronous pulley 8 is connected to the transmission wheel 10 through the synchronous belt, and the transmission wheel 10 is connected to another transmission wheel 10 through the synchronous belt. The transmission wheel 10 is connected to the synchronous pulley 12 through the belt. When the transmission wheel 10 rotates, it can drive the synchronous pulley 12 to rotate, so that all the rotating rods 4 can rotate synchronously. The synchronous pulley 12 is connected to the rotating rod 4. The transmission wheel 10 includes two fixedly connected synchronous pulleys that can rotate simultaneously. One pulley is driven by synchronous pulley 8, while the other drives synchronous pulley 12 via a synchronous belt. The transmission wheel 10 is connected to the rotating rod 4. One synchronous pulley in the upper transmission wheel 10 is connected to synchronous pulley 8 via a synchronous belt, and the other synchronous pulley is connected to one synchronous pulley in the lower transmission wheel 10 via a synchronous belt. The other synchronous pulley in the lower transmission wheel 10 is connected to synchronous pulley 12 via a synchronous belt. The drive end of the motor 6 is fixedly connected to the drive gear 13, and the non-drive end of the motor 6 is connected to the mounting bracket 1. The outer wall of the duct 7 is connected to the top of the baffle 5 via bolts, and the duct 7 passes through the baffle 5. The dust collection device can suck away foreign objects blown up by the ion bar from the end of the air hood 14 where the guide plate 15 is located through the duct 7, preventing the foreign objects from falling back onto the PCB board. The rotating rod 4 has a rotating shaft 11 at both ends, which is connected to the mounting bracket 1. The rotating rod 3 can rotate freely through the rotating shaft 11. The outer wall of the mounting bracket 1 is bolted to an outer shell plate 2, and an alarm light 3 is installed at the top of the top outer shell plate 2.

[0027] Working principle: First, the PCB board is placed between the upper and lower rollers. The motor 6 drives the drive gear 13 to rotate, which in turn drives the two driven gears 9 that mesh with it. The driven gears 9 rotate, which in turn drives the synchronous pulley 8 that is fixed to them. This causes the synchronous pulley 8 to rotate via a synchronous belt, which in turn drives the transmission pulley 10 to rotate. One of the transmission pulleys 10 is driven by the synchronous pulley 8, while the other drives the synchronous pulley 12 via a synchronous belt. This causes multiple rotating rods 4 to rotate, thus conveying the PCB board. As the PCB board moves, the ion fan blows ion air from the side of the ion fan bar closest to the PCB board through the air pipe, thus blowing away foreign objects on the PCB board. At the same time, the dust collection device sucks away the foreign objects blown up by the ion fan bar from the end of the air hood 14 where the guide plate 15 is located through the air pipe 7, preventing the foreign objects from falling back onto the PCB board, thus achieving a one-time cleaning of both sides of the PCB.

[0028] It is worth noting that the circuits, protection devices, dust collection devices, ionizers and ion fans, and alarm lights 3 involved in the above embodiments all adopt the corresponding existing technologies according to the actual situation, so they will not be described in detail in the embodiments of this application.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
