Description

Technical Field

[0001] This invention relates to the field of PCB circuit board etching equipment technology, specifically to a PCB circuit board etching equipment and method. Background Technology

[0002] PCB etching refers to the process of removing unwanted copper foil from a circuit board using chemical methods to form the desired circuit pattern. Etching is a key step in the PCB manufacturing process and is usually done using the "pattern plating method". This involves pre-plating a lead-tin resist layer on the copper foil that needs to be retained on the outer layer of the circuit board, and then chemically etching away the remaining copper foil.

[0003] Existing PCB etching equipment cannot perform integrated production processes, allowing etching and subsequent surface treatment to be handled in one step to improve production efficiency. Therefore, a structure is needed to solve the above problems. Summary of the Invention

The upper end of the first electro-hydraulic rod is fixedly connected to the fixed plate. The side end of the fixed plate is fixedly connected to the track plate, and the rear end of the fixed plate is equipped with the second electro-hydraulic rod. The second electro-hydraulic rod controls the connecting guide rod to slide on the track plate. The side end of the connecting guide rod is fixedly connected to the push rod.

[0009] Specifically, the immersion etching component includes a guide seat, a connecting mating seat, a sealing guide seat, a liquid reservoir, and a guide control seat. The lower end of the sealing guide seat is fixedly connected to the liquid reservoir, and the connecting mating seat is installed on the sealing guide seat. The side end of the connecting mating seat is connected to the guide seat. The lower end of the liquid reservoir is provided with a guide control seat, and the liquid reservoir is connected to the guide control seat.

[0010] Specifically, the cleaning component includes a positioning detector, a mounting plate, a fixed side guard plate, a limiting mechanism, and a cleaning mechanism. The upper end of the fixed side guard plate is fixedly connected to the mounting plate, the positioning detector is mounted on the mounting plate, the cleaning mechanism is provided at the center limit of the mounting plate, and the limiting mechanism is fixedly mounted on the fixed side guard plate.

[0011] Specifically, the limiting mechanism includes a fixed partition, a front guide plate, a control seat, a hydraulically controlled telescopic rod, and a limiting crossbar. The front guide plate is fixedly connected to the front end of the fixed partition, and the control seat is installed on the front guide plate. The control seat controls the extension and retraction adjustment of the hydraulically controlled telescopic rod, and a limiting crossbar is provided at the lower end of the hydraulically controlled telescopic rod.

[0012] Specifically, the cleaning mechanism includes a mating limiting fixed seat, a positioning hinge seat, an electric telescopic control link, a pushing hinge seat, an installation adapter plate, and a grinding disc. The lower end of the mating limiting fixed seat is telescopically connected to the pushing hinge seat, and the side end of the pushing hinge seat is hinged to the electric telescopic control link. The positioning hinge seat is hinged to the electric telescopic control link.

[0013] Specifically, an installation adapter plate is installed at the lower end of the push hinge seat, and a grinding disc is rotatably connected to the lower end of the installation adapter plate.

[0014] Specifically, the center limit fixing of the matching limiting fixing seat and the mounting support plate is fixed, the fixing partition plate is fixedly connected to the fixing side guard plate, the control seat controls the height of the limiting crossbeam through a hydraulically controlled telescopic rod, and the positioning hinge seat is fixedly connected to the fixing side guard plate.

[0015] Specifically, the second electro-hydraulic rod changes the lateral position of the push rod through the connecting guide rod, and the push rod contacts the storage seat, pushing the storage seat to rotate and adjust through the spring docking shaft. The lower end of the fixed plate is fixedly connected to the sealing guide seat, and the support bracket is fixedly connected to the side end of the sealing guide seat.

[0016] A method of using a PCB circuit board etching processing equipment includes the following steps:

[0017] S1. First, the etching solution is introduced through the connecting mating seat. The connecting mating seat is connected to the guide seat, so that the etching solution reaches the inside of the liquid storage seat through the sealed guide seat. At the same time, the PCB board is placed inside the liquid storage seat. Under the control of the first electric hydraulic rod, it is extended, so that the PCB board descends into the inside of the liquid storage seat and the etching work is completed inside the liquid storage seat.

[0018] S2. Then, the first electro-hydraulic rod retracts, causing the storage seat to adjust its height, which in turn causes the PCB board to adjust its height. After a certain period of time, the surface of the PCB board dries. Then, the second electro-hydraulic rod controls the extension adjustment of the connecting guide rod. The connecting guide rod slides at the upper limit of the track plate, which can change the position of the push rod. At the same time, the push rod can contact the storage seat and push the storage seat to rotate around the spring docking shaft.

[0019] S3. After that, the first robotic arm and the second robotic arm work to place the PCB board in the storage seat onto the transfer seat. The support bracket controls the transfer seat to transfer the PCB board. When the PCB board reaches the lower end of the position detector, the position detection work can be performed. At this time, the transfer seat stops transferring the PCB board. At the same time, the control seat works to control the position of the limit crossbar through the hydraulic control telescopic rod, so that the limit crossbar contacts and limits the PCB board.

[0020] S4. Finally, the cleaning mechanism operates. The electric telescopic control linkage inside the cleaning mechanism extends, causing the push hinge to extend on the mating limiting fixed seat, changing the position of the mounting adapter plate and the polishing disc. The lower end of the electric telescopic control linkage is hinged to the push hinge plate. The mounting adapter plate is equipped with an independent motor that can control the rotation of the polishing disc, thereby performing surface cleaning and polishing work on the PCB board through the polishing disc.

[0021] The beneficial effects of this invention are:

[0022] First, the present invention facilitates etching work through the structural design of the etching process. The connecting mating seat can introduce etching solution through the guide seat, allowing the etching solution to be stored in the reservoir. Later, the solution can be guided out through the guide control seat. At the same time, the setting of the control and adjustment components facilitates the limiting installation of the PCB board. The PCB board is placed inside the storage seat, and the position of the PCB board can be changed by the extension and retraction adjustment of the first electro-hydraulic rod. Later, the position of the connecting guide rod can be controlled by the second electro-hydraulic rod, causing the push rod to push the storage seat, which rotates to a certain extent through the spring docking shaft. This facilitates cooperation with the first and second robotic arms to pick up the PCB board.

[0023] Second, the present invention facilitates secondary processing of PCB boards through the structural design of the surface cleaning structure. The PCB board can be transmitted to the lower end of the cleaning component through the transmission seat. When the position detector detects the PCB board, the hydraulic control telescopic rod and the limiting crossbar can be extended through the control seat, so that the limiting crossbar limits the PCB board. Then, the electric telescopic control linkage in the cleaning mechanism extends, pushing the hinge seat to extend and changing the position of the mounting adapter plate and the grinding disc. At the same time, the grinding disc is driven by an independent motor, thereby cleaning and grinding the surface of the PCB board. Attached Figure Description

[0046] The cleaning component 23 includes a positioning detector 25, a mounting plate 26, a fixed side guard plate 27, a limiting mechanism 28, and a cleaning mechanism 29.

Etching is completed within the reservoir 18. After etching, the first electro-hydraulic rod 8 retracts, adjusting the height of the storage seat 11 and thus the PCB board. After a certain period of time, the PCB board surface dries. Then, the second electro-hydraulic rod 14 controls the extension and adjustment of the connecting guide rod 12. The connecting guide rod 12 slides at the upper limit of the track plate 13, changing the position of the push rod 9. Simultaneously, the push rod 9 contacts the storage seat 11, pushing the storage seat 11 to rotate around the spring docking shaft 10. Then, the first robotic arm... 2. The second robotic arm 3 operates by placing the PCB board from the storage seat 11 onto the transfer seat 20. The support bracket 21 controls the transfer seat 20 to transfer the PCB board.

The electric telescopic control link (37) in the cleaning mechanism (29) extends, causing the push hinge (38) to extend on the mating limiting fixed seat (35), changing the position of the mounting adapter plate (39) and the polishing disc (40). The lower end of the electric telescopic control link (37) is hinged to the push hinge plate (38). The mounting adapter plate (39) is equipped with an independent motor that can control the rotation of the polishing disc (40), thereby performing surface cleaning and polishing work on the PCB board through the polishing disc (40).
