Description

Technical Field

[0001] The present invention belongs to the field of PCB board production, and particularly relates to an ink spraying device for PCB board production. Background Art

[0002] In the manufacturing process of modern electronic devices, as one of the core components, the production quality of PCB boards is directly related to the performance and reliability of the final products. Ink spraying is an important step in the PCB board production process, mainly used for forming solder mask layers, character markings, etc. With the development of electronic technology, higher requirements are put forward for the accuracy and production efficiency of PCB boards.

[0003] In the traditional PCB board ink spraying process, since it is necessary to spray ink on both sides of the PCB board to meet different functional requirements or design requirements, when implementing double-sided spraying, the common practice is to flip the PCB board by a manipulator or other means after spraying one side to spray the other side. However, in this process, there are obvious efficiency bottlenecks:

[0004] Most current automated production lines must first pause the conveying system of the PCB board when performing the flipping operation of the PCB board in order to safely perform the flipping operation. This process not only increases the overall processing time but also significantly reduces the production efficiency.

[0005] Therefore, it is urgent to develop an ink spraying device for PCB board production that can achieve efficient and continuous double-sided ink spraying operations. Summary of the Invention

[0006] In order to overcome the above-mentioned disadvantages of the prior art, the purpose of the present invention is to provide an ink spraying device for PCB board production that can achieve efficient and continuous double-sided ink spraying operations.

[0007] The technical solution is as follows: An ink spraying device for PCB board production includes a cabinet, a conveying component, a flipping structure, and an inkjet mechanism. Conveying components are arranged on both the left and right sides inside the cabinet, and the conveying component on the left side is higher than the conveying component on the right side. A flipping structure is arranged in the middle of the cabinet, and the flipping structure is located between the conveying components on the left and right sides. The flipping structure consists of a cylinder and a spiral plate. The spiral plate is twisted 180 degrees, and the spiral plate is installed inside the cylinder. An inkjet mechanism is arranged on the cabinet above the conveying component.

[0008] Further, the conveying component includes conveying wheels, and a row of conveying wheels are installed on both the left and right sides inside the cabinet.

[0009] Further, the conveying assembly further includes a motor, a transmission pulley group and a push rod. Motors are symmetrically arranged front and back on the cabinet above the conveying wheels. Transmission pulley groups are connected to the output shafts of the motors. Push rods are evenly spaced on the conveyor belts of the transmission pulley groups.

[0010] Further, the inkjet mechanism includes a Y-axis module, an X-axis module, a vertical guide rod, a first cylinder and a nozzle. Y-axis modules are symmetrically arranged left and right at the inner top of the cabinet above the conveying assembly. X-axis modules are connected to the sliders of the Y-axis modules. Vertical guide rods extending downward are connected to the sliders of the X-axis modules. A nozzle is slidably connected to the vertical guide rod. A first cylinder is arranged on the vertical guide rod. The telescopic end of the first cylinder is connected to the nozzle.

[0011] Further, a temperature sensor and a temperature controller are further included. A temperature sensor is installed in the cabinet. A temperature controller is arranged at the left part of the cabinet. The temperature controller is linearly connected to the temperature sensor.

[0012] Further, a cooling fan is further included. A cooling fan is arranged at the right part of the cabinet.

[0013] Further, a cleaning mechanism is further included. A cleaning mechanism is installed between the upper and lower parts of the left conveying assembly. The cleaning mechanism includes a second cylinder, a lifting plate, a concave mounting plate, a spring, a cleaning cylinder and a motor. Second cylinders are installed above and below the left conveying assembly. The telescopic ends of the second cylinders are oppositely installed. The telescopic ends of the second cylinders are both connected to the lifting plate. Concave mounting plates are vertically slidably connected to the opposite sides of the lifting plate. Springs are connected between the concave mounting plates and the lifting plates. A cleaning cylinder is rotatably installed in the concave mounting plate. A motor is installed at the end of the concave mounting plate. The output shaft of the motor is axially connected to the end of the cleaning cylinder.

[0014] Further, a collection mechanism is further included. Collection mechanisms are symmetrically arranged left and right at the lower part of the cabinet. The collection mechanisms are below the cleaning mechanism. The collection mechanism includes an inclined plate, an electric track, a plug and a collection box. Inclined plates tilting inward are symmetrically arranged left and right at the lower part of the cabinet. Electric tracks are arranged on the front and back sides of the inclined plates. A plug is connected between the sliders of the electric tracks. Collection boxes are arranged inside the cabinet on the inner sides of the inclined plates. There is a blanking pipe at the bottom of the collection box.

[0015] The beneficial effects are as follows: After the upper surface of the PCB board is sprayed in the present invention, the PCB board passes through the turning structure. The turning structure automatically turns over the PCB board. The turned-over PCB board falls on the conveying assembly on the right side, and then the other side of the PCB board can be sprayed. The equipment can work continuously, improving work efficiency. The outer surface of the PCB board can be wiped by the cleaning cylinder. At the same time, through the holes on the cleaning cylinder, the impurities on the outer surface of the PCB board can be sucked away. The PCB board after cleaning can be better sprayed, improving the spraying quality. Brief Description of the Drawings

Detailed Description of the Invention

[0026] The following is a specific introduction to the present invention in combination with the drawings and specific embodiments.

[0027] Embodiment: An ink spraying device for PCB board production, as Figures 1-9As shown in the figure, it includes a cabinet 1, a conveying component 2, a turning structure 3, and an inkjet mechanism 4. Conveying components 2 are arranged on both the left and right sides inside the cabinet 1. The conveying component 2 on the left side is higher than the conveying component 2 on the right side. Materials are put in from the left side of the equipment, and the materials after spraying are sent out from the right side of the equipment. A turning structure 3 is arranged in the middle of the cabinet 1. By changing the base surface of the material, the effect of turning is achieved. The turning structure 3 is located between the conveying components 2 on the left and right sides. The turning structure 3 is composed of a cylinder and a spiral plate. The spiral plate is twisted 180 degrees, and the spiral plate is installed inside the cylinder. An inkjet mechanism 4 is arranged on the cabinet 1 above the conveying component 2. During the working process of the inkjet mechanism 4, it needs to be connected to the ink inlet.

[0028] As Figure 3 and Figure 4 shown in the figure, the conveying component 2 includes conveying wheels 21, motors 22, transmission pulley sets 23, and push rods 24. A row of conveying wheels 21 are installed on both the left and right sides inside the cabinet 1. Motors 22 are symmetrically arranged front and back on the cabinet 1 above the conveying wheels 21. Transmission pulley sets 23 are connected to the output shafts of the motors 22. Push rods 24 are evenly spaced on the conveyor belts of the transmission pulley sets 23. The spacing between the push rods 24 is the same as the length of the PCB board. When the PCB board is placed on the conveying wheels 21, when the push rods 24 pass over the PCB board, the push rods 24 can push the PCB board to move to the right, and the PCB board can prevent the PCB board from shifting during the conveying process.

[0029] As Figure 6 and Figure 7 shown in the figure, the inkjet mechanism 4 includes a Y-axis module 41, an X-axis module 42, a vertical guide rod 43, a first cylinder 44, a nozzle 45, a temperature sensor 46, a temperature controller 47, and a cooling fan 48. Y-axis modules 41 are symmetrically arranged left and right at the top inside the cabinet 1 above the conveying component 2. X-axis modules 42 are connected to the sliders of the Y-axis modules 41. Vertical guide rods 43 extending downward are connected to the sliders of the X-axis modules 42. A nozzle 45 is slidably connected to the vertical guide rods 43. A first cylinder 44 is arranged on the vertical guide rods 43. The telescopic end of the first cylinder 44 is connected to the nozzle 45. A temperature sensor 46 is installed inside the cabinet 1. A temperature controller 47 is arranged on the left side inside the cabinet 1. The temperature controller 47 is linearly connected to the temperature sensor 46. A cooling fan 48 is arranged on the right side inside the cabinet 1; when the equipment sprays the PCB board, when the temperature sensor 46 detects an error in the temperature inside the cabinet 1, the temperature sensor 46 controls the temperature controller 47 to start working. The temperature controller 47 maintains the temperature inside the cabinet 1 at the set value. During the process of the PCB board being conveyed to the right, the cooling fan 48 is controlled to start working, so that the sprayed side of the PCB board can solidify faster, preventing damage to the sprayed side of the PCB board during the turning process.

[0030] As Figure 8As shown in the figure, it further includes a cleaning mechanism 5. A cleaning mechanism 5 is installed between the upper and lower parts of the left conveying component 2. The cleaning mechanism 5 includes a second cylinder 51, a lifting plate 52, a concave mounting plate 53, a spring 54, a cleaning cylinder 55, and a motor 56. Second cylinders 51 are installed above and below the left conveying component 2. The telescopic ends of the second cylinders 51 are oppositely installed. The telescopic ends of the second cylinders 51 are both connected to a lifting plate 52. Concave mounting plates 53 are vertically slidably connected to the opposite sides of the lifting plate 52. A spring 54 is connected between the concave mounting plate 53 and the lifting plate 52. A cleaning cylinder 55 is rotatably installed inside the concave mounting plate 53. The inside of the cleaning cylinder 55 is hollow, and through holes are provided on the outer side surface of the cleaning cylinder 55. There is a connector connected to an air pipe at the rear side of the cleaning cylinder 55. A motor 56 is installed at the end of the concave mounting plate 53. The output shaft of the motor 56 is axially connected to the end of the cleaning cylinder 55. When spraying the PCB board, by controlling the second cylinder 51 to drive the cleaning cylinder 55 to perform vertical adjustment, so that during the conveying process of the PCB board, the outer surface of the PCB board can be attached to the outer surface of the cleaning cylinder 55. At the same time, connect the air pipe to the cleaning cylinder 55 and control the motor 56 to drive the cleaning cylinder 55 to rotate. When the PCB board passes by, the outer surface of the PCB board can be wiped by the cleaning cylinder 55. At the same time, through the holes on the cleaning cylinder 55, the impurities on the outer surface of the PCB board can be sucked away. After the equipment finishes working, control the motor 56 to stop working, and at the same time drive the cleaning cylinder 55 to reset by the second cylinder 51.

[0031] As Figure 9 shown in the figure, it further includes a collection mechanism 6. Collection mechanisms 6 are symmetrically arranged on the left and right at the lower part inside the cabinet 1. The collection mechanism 6 is below the cleaning mechanism 5. The collection mechanism 6 includes an inclined plate 61, an electric track 62, a plug 63, and a collection box 64. Inclined plates 61 that are inclined inward are symmetrically arranged on the left and right at the lower part inside the cabinet 1. Electric tracks 62 are arranged on the front and rear sides of the inclined plate 61. A plug 63 is connected between the sliders of the electric track 62. The electric track 62 can drive the plug 63 to slide along the top of the inclined plate 61. Collection boxes 64 are arranged inside the cabinet 1 on the inner sides of the inclined plates 61. There is a blanking pipe at the bottom of the collection box 64. The impurities cleaned by the cleaning cylinder 55 fall on the inclined plate 61. When it is necessary to clean the inclined plate 61, drive the plug 63 to move on the upper surface of the inclined plate 61 by the electric track 62, sweep the impurities on the upper surface of the inclined plate 61 into the collection box 64, and discharge them through the collection box 64. After the inclined plate 61 is cleaned, control the electric track 62 to stop working.

[0032] During use: When it is necessary to use this device for ink spraying on a PCB board, first control the conveying wheel 21 and the motor 22 to rotate clockwise simultaneously. Then place the PCB board to be ink-sprayed on the left conveying assembly 2. The conveying wheel 21 drives the PCB board to be conveyed to the right. During the conveyance of the PCB board, the push rod 24 passes over the PCB board. The push rod 24 can push the PCB board to move to the right, and the PCB board can prevent the PCB board from shifting in position during conveyance. When the PCB board is conveyed to the lower part of the inkjet mechanism 4 on the left, the horizontal position of the nozzle 45 can be adjusted through the Y-axis module 41 and the X-axis module 42, and the vertical position of the nozzle 45 can be adjusted through the first cylinder 44. Subsequently, ink spraying operation is performed on the PCB board through the nozzle 45. After the upper surface of the PCB board is sprayed, the PCB board passes through the turning structure 3. After the turning structure 3 turns over the PCB board, it falls on the right conveying assembly 2. The right conveying assembly 2 continues to convey the PCB board, and the right inkjet mechanism 4 continues to perform ink spraying operation on the turned-over PCB board. The PCB board after the spraying operation is conveyed out from the right side of the cabinet 1. Repeat this process until all PCB boards are sprayed, and then control the device to stop working.
