Description

Technical Field

[0001] The utility model belongs to the technical field of automation equipment and relates to a cleaning inspection machine. Background Art

[0002] PCB, whose Chinese name is printed circuit board, also known as printed circuit board, is an important electronic component, a support for electronic components, and a carrier for electrical connections of electronic components. Because it is made using electronic printing technology, it is called a "printed" circuit board.

[0003] During the processing, for high efficiency, printed circuit boards are often multi-connected boards, so a cutting machine or splitter is needed to cut and separate the boards. During the separation process, the PCB boards are easily contaminated with dust.

[0004] Therefore, it is often necessary to clean all or part of the printed circuit board. If the cleaning and drying procedures are used, it will be time-consuming, cumbersome, inefficient and inconvenient to use. Therefore, we propose a cleaning inspection machine. Utility Model Content

[0005] The purpose of the utility model is to provide an automatic cleaning machine.

[0006] In order to solve the above problems, the utility model provides a cleaning inspection machine, which is characterized in that it includes this machine, a cleaning unit, an inspection unit, a dust collection unit, and a central control unit; the cleaning unit includes a moving device and a cleaning device; the inspection unit includes a transport device and an inspection device; the entrance is located on the right side of the cleaning unit of this machine, and the equipment outlet is located on the left side of the inspection unit of this machine.

[0007] Wherein: the moving device is also equipped with a left suction cup and a right suction cup, which are controlled to move by the central control unit to place the PCB boards respectively.

[0008] The cleaning device includes an ion wind rod, a card slot, a dust removal hopper, a support plate, and a dust suction port. The card slot is placed on the support plate. Below the dust suction port is a dust collecting unit. The dust cleaned into the dust removal hopper will be sucked into the dust collecting unit.

[0009] The transport device is driven by a servo motor to drive a synchronous shaft, which causes the synchronous belt to start moving and transport the PCB board through the inspection device.

[0010] The inspection device includes a barcode scanner and a camera. When the barcode scanner scans and finds an unqualified PCB board, the push cylinder pushes the PCB board and screens it out through the slide plate; qualified products go to the next step of inspection, the positioning cylinder assembly positions the PCB board, the light source assembly turns on the light, and the camera transmits information to the central control unit to detect and cut unqualified PCB boards; the positioning cylinder assembly includes a front positioning cylinder and a rear positioning cylinder, and the light source assembly includes a front light source and a rear light source.

[0011] At the equipment outlet, there is a transmission shaft below the belt, and a transmission card is fixed above the belt. The transport cylinder rotates the transmission shaft, and the PCB board is clamped into the transmission clamp and transported to the next equipment.

[0012] The beneficial effect of the present invention is that the cleaning and inspection machine adopts an ion wind rod to produce strong wind to blow away dust, which saves more time compared with processes such as water cleaning and drying, and the combination of cleaning and inspection greatly improves efficiency.

[0025] The specific implementation of the present invention is described in further detail below: Figure 1As shown, the utility model provides a cleaning inspection machine, including this machine 1; a dust collection unit 3; a central control unit 5; a cleaning unit 6; and an inspection unit 7, wherein the inlet 4 is located on the right side of the cleaning unit 6, and the equipment outlet 2 is located on the left side of the inspection unit.

[0026] The cleaning unit 6 includes a moving device 61 and a cleaning device 62 .

[0027] The testing unit 7 includes a transport device 71 and a testing device 72 .

[0028] in:

[0029] The equipment outlet 2 includes a servo motor 21 , a belt 22 , a transmission card 23 , and a transmission shaft 24 .

[0030] The moving device 61 includes a right suction cup 611 and a left suction cup 612 .

[0031] The cleaning device 62 includes an ion wind rod 621 , a slot 622 , a dust hopper 623 , a support plate 624 , and a dust suction port 625 .

[0032] The card slot 622 is placed on a support plate 624 , and the support plate 624 is fixed on the dust hopper 623 .

[0033] The transport device 71 includes a servo motor 711 , a synchronous belt 712 , and a synchronous shaft 713 .

[0034] The inspection device 72 includes a scanning gun 721 , a pushing cylinder 722 , a slide plate 723 , a camera 724 , a positioning cylinder assembly 725 , and a light source assembly 726 .

[0035] Implementation steps:

[0036] The PCB board enters the cleaning unit 6 from the entrance 4. The central control unit 5 controls the movement of the mobile device 61. The mobile device 61 uses the right suction cup 611 to suck the incoming PCB board, and the left suction cup 612 sucks the PCB board on the card slot 622. The mobile device 61 moves to the left, the left suction cup 612 places the PCB board on the synchronous belt 712, and the right suction cup 611 places the PCB board on the card slot 622.

[0037] When the PCB board is placed in the card slot 622, the ion wind rod 621 starts to work, and the strong wind speed blows away the dust, and the dust falls into the dust hopper 623, and the dust collection unit 6 collects the dust through the dust suction port 625.

[0038] When the PCB board is placed on the synchronous belt 712, the PCB board is transported to the inspection device 72 area, and the scanning gun 721 scans the PCB board. When the code on the PCB board is scanned, it is sent to the next step. When the code on the PCB board cannot be scanned, the PCB board is scrapped and is pushed out of the synchronous belt 712 by the pushing cylinder 722, and the scrapped product is sent out from the slide plate 723.

[0039] When the PCB board reaches the positioning cylinder assembly 725, the positioning cylinder assembly 725 pushes the PCB board to the inspection center position and then retracts. The light source assembly 726 turns on the light source, and the camera 724 compares the cutting marks on both sides of the PCB board through the light source of the light source assembly 726 to see if they are flat. If not, the central control unit 5 will issue a prompt, and the unqualified PCB board will be manually taken out, and the PCB board that meets the standards will be transported to the next location.

[0040] The PCB board is transported to the equipment outlet 2, and the servo motor 21 rotates the transmission shaft 24, which drives the belt 22 to move. A transmission card 23 is fixed on the belt 22, and the PCB board is clamped on the transmission card 23 and transported to the next equipment by the belt 22.

[0041] The above embodiment is only one embodiment of the present invention. Although the description is relatively specific and detailed, it should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art can make a number of modifications and improvements without departing from the concept of the present invention, and these modifications and improvements are all within the scope of protection of the present invention.
