Description

Technical Field

[0001] The present application relates to the technical field of PCB board processing, and specifically to a PCB board processing device. Background Art

[0002] PCB board is a circuit board. With the increasing development of LED technology, LED products are more and more widely used in people's daily lives. PCB board is an important component of LED products. PCB board needs to be processed by die bonding. After die bonding, welding operation is required on the crystal.

[0003] The existing patent (publication number: CN 207665288U) discloses a new type of PCB board fixture for a crystal bonding machine, including a fixture frame and a PCB board placement plate. The PCB board placement plate is arranged in the middle position of the fixture frame, and fixed connecting plates are provided on the left and right sides of the PCB board placement plate. The left and right ends of the PCB board placement plate are fixedly connected to the fixture frame through fixed connecting plates. A slide rail is provided on the top of the PCB board placement plate, and the slide rail is fixedly connected to the inside of the fixture frame. A movable baffle is installed on the slide rail, and fastening adjustment bolts are provided on the left and right ends of the movable baffle. A slide groove is also provided on the movable baffle, and the movable baffle is movably connected to the slide rail through the slide groove. A movable drawer is also provided at the bottom of the PCB board placement plate, and the movable drawer is arranged at the lower side of the fixture frame. The overall fixture structure is simple, which is convenient for adjusting and fixing PCB boards of different widths, convenient for recycling packaging materials, and lower packaging costs.

[0004] The above-mentioned PCB board fixture is relatively simple, and multiple steps of manual operation are required to position the PCB board. In addition, manual pick-up and transfer are required to complete different processing steps, which is not convenient for continuous processing. At the same time, dust on the PCB board will affect the quality of the finished product after die bonding and welding. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the present application provides a PCB board processing device, which has the advantages of facilitating the positioning of PCB boards, saving manpower, and being able to perform continuous processing, thereby improving the efficiency of PCB board processing operations. At the same time, it can also clean the PCB boards while they are moving, thereby ensuring the processing quality of the PCB boards. This solves the problem that the existing PCB board fixtures are relatively simple, require multiple steps of manual operation when positioning the PCB boards, and require manual pick-up and placement to complete different processing steps, which is not convenient for continuous processing operations. At the same time, the dust on the PCB boards will affect the quality of the finished products after crystal bonding and welding.

[0006] The top of the base is fixedly connected to the base, and the internal circumference of the cleaning roller is connected to the second conveying roller of the base, and a conveyor belt is driven by the second conveying roller. The upper surface of the conveyor belt is symmetrically provided with two positioning plates, and the outer surface of each positioning plate is fixedly connected to a fixing rod, and the outer circumferential surface of the fixing rod is slidably plugged into the inner circumference of the base. The bottom of the base is rotatably connected to a screw rod, and the outer circumferential surface of the screw rod is threadedly connected to two threaded tubes, and the outer circumferential surface of each threaded tube is fixedly connected to a connecting plate, and the top of the connecting plate is fixedly sleeved with the outer circumferential surface of the fixing rod respectively. The upper surface of the base is fixedly connected to a top plate, and the internal circumference of the top plate is rotatably connected to a cleaning roller, and the outer circumferential surface of the cleaning roller is driven by a second connecting belt, and the other end of the second connecting belt is driven by one of the conveying rollers. A crystal bonding device is provided above the base, and a welding device is provided above the base.

[0007] Through the above solution, since the existing PCB board fixture is relatively simple, multi-step manual operation is required for positioning the PCB board, and manual picking, placement and transfer are required to complete different processing steps, which is not convenient for continuous processing. At the same time, dust on the PCB board will affect the quality of the finished product after crystal bonding and welding. By providing a conveyor roller and a conveyor belt, the PCB board can be continuously moved for processing. By providing a cleaning roller and using a second connecting belt to achieve linkage between the conveyor roller and the cleaning roller, the PCB board can be cleaned during the movement, thereby ensuring the quality of subsequent processing of the PCB board. The threaded tube is driven to move in relative directions by the rotation of the screw rod, which prompts the connecting plate to drive the fixing rod and the positioning plate to move and retract, thereby automatically positioning PCB boards of different sizes, saving manpower and improving work efficiency.

[0008] Furthermore, the outer surface of each positioning plate is fixedly connected to two sliding rods, the outer circumferential surface of the sliding rod is slidably plugged into the inner part of the base, and the outer circumferential surface of each sliding rod is fixedly connected to a first limiting ring.

[0009] Through the above solution, the sliding rod can support and reinforce the positioning plate, prompting the positioning plate to always move laterally, thereby improving the stability of the positioning plate movement. The first limiting ring can limit the sliding rod to prevent the sliding rod from easily falling off the base.

[0010] Furthermore, the screw rod is a bidirectional screw rod, and both ends of the screw rod are fixedly sleeved with a second limiting ring.

[0011] Through the above scheme, the bidirectionally arranged screw rod can prompt the threaded tube to move in relative directions, thereby causing the positioning plate to retract and move, thereby completing the positioning operation of the PCB board. The second limiting ring can restrict the threaded tube to prevent the threaded tube from easily falling off the screw rod.

[0012] Furthermore, a first motor is provided inside the bracket, the front of the first motor is connected to a first connecting belt through an output shaft, the top of the first connecting belt is connected to the outer circumferential surface of the screw rod, and a second motor is provided on the back of one of the conveying rollers.

[0013] Through the above solution, the first motor and the first connecting belt can be used to drive the screw to rotate, providing power for the screw, and the second motor can be used to drive one of the conveying rollers to rotate, thereby driving the conveyor belt to operate.

[0014] Furthermore, a dust collection device is provided on the upper surface of the top plate, and dust collection pipes arranged at equal distances are fixedly connected to both sides of the dust collection device.

[0015] Through the above solution, the dust cleaned by the cleaning roller can be recovered through the dust suction equipment and the dust suction pipe, thereby preventing the dust from spreading and polluting the working environment.

[0016] Furthermore, a dust collection box is slidably connected to the interior of the dust collection device.

[0017] Through the above solution, the recovered dust is stored in the dust box, which makes it easy to clean the dust in the dust box.

[0018] Furthermore, the bottom of each of the dust suction pipes is inclined at a certain angle toward the bottom of the cleaning roller.

[0019] Through the above solution, the dust collection tube can collect dust more efficiently, preventing dust from spreading and contaminating the working environment and PCB boards.

[0020] Furthermore, the outer layer of the cleaning roller is a soft brush structure.

[0021] Through the above solution, the cleaning roller with a soft brush outer layer can protect the PCB board and prevent the PCB board from being damaged during the cleaning process.

[0022] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0023] The PCB processing device, by providing conveyor rollers and a conveyor belt, enables continuous movement and processing of PCB boards. A cleaning roller is provided, and a second connecting belt is used to achieve linkage between the conveyor roller and the cleaning roller, so that the PCB boards can be cleaned during movement, thereby ensuring the quality of subsequent processing of the PCB boards. The threaded tube is driven in relative directions by the rotation of the lead screw, which causes the connecting plate to drive the fixing rod and the positioning plate to move and retract, thereby automatically positioning PCB boards of different sizes. This saves manpower and improves operating efficiency. It solves the problems of existing PCB processing fixtures that are highly dependent on manpower, cannot perform continuous processing, cannot clean PCB boards, and have low flexibility and practicality.

[0039] A PCB processing device in this embodiment facilitates continuous movement and processing of PCBs by providing a conveyor roller 3 and a conveyor belt 4. A cleaning roller 16 is provided, and a second connecting belt 17 is used to achieve linkage between the conveyor roller 3 and the cleaning roller 16, so that the PCBs can be cleaned during movement, thereby ensuring the quality of subsequent processing of the PCBs. The threaded tube 8 is moved in relative directions by the rotation of the lead screw 7, prompting the connecting plate 9 to drive the fixing rod 6 and the positioning plate 5 to move and retract, thereby automatically positioning PCBs of different sizes.

[0040] It should be noted that the dust suction pipes 19 on both sides of the dust suction device 18 are symmetrically arranged.

[0041] The working principle of the above embodiment is:

[0042] When it is necessary to process the PCB board, the second motor 21 can be started to drive one of the conveying rollers 3 to rotate, prompting the conveyor belt 4 to operate, placing the PCB board on the conveyor belt 4, and then the PCB board moves forward following the conveyor belt 4. When the conveying roller 3 rotates, it will drive the cleaning roller 16 to rotate through the second connecting belt 17. When the PCB board moves under the cleaning roller 16, the rotating cleaning roller 16 will clean the surface of the PCB board to ensure the quality of subsequent processing operations. The cleaned dust will be recovered by the dust collection device 18 above through the dust collection pipe 19 to prevent dust from polluting the working environment. After the PCB board is cleaned, it will move forward as needed. When the PCB board moves to the bottom of the crystal bonding device 22, the conveyor belt 21 will be put into operation. The conveyor belt 4 stops running, and the first motor 13 is started as power to drive the screw rod 7 to rotate through the output shaft and the first connecting belt 14. The screw rod 7 moves in the relative direction through the threaded tube 8, and the threaded tube 8 drives the fixing rod 6 to move in the relative direction through the connecting plate 9. The fixing rod 6 drives the positioning plate 5 to move in the relative direction, prompting the positioning plate 5 to clamp the PCB board on the conveyor belt 4 and position it. The crystal bonding equipment 22 can be started to perform the crystal bonding operation. After the crystal bonding operation is completed, the positioning restriction of the positioning plate 5 on the PCB board can be released first, and the conveyor belt 4 can be driven to drive the PCB board to move to the bottom of the welding equipment 23, and then it is positioned again by the positioning plate 5 for subsequent welding operations.
