Description

Technical Field

[0001] The invention belongs to the technical field of wet process of circuit boards, and in particular relates to a wet process processing device for circuit boards. Background Art

[0002] The copper deposition, electroplating, and desmearing processes of circuit board manufacturing are called wet processes. In the wet process processing, horizontal processing lines or gantry processing lines are currently used. The characteristics of these two processing lines are as follows: 1. Using gantry processing lines: Gantry processing lines, that is, the troughs of each processing process are arranged in parallel in sequence, and the overhead crane frame and the transport crane device (commonly known as the gantry frame) mounted above the cylinder body are used to control the boards to be plated in the plug-in board frame to pass through the processing of each cylinder body in sequence according to the program control to complete the wet process processing. During processing, it is necessary to use manpower first, or use equipment to load the copper deposition board into the copper deposition basket, and then manually drop it on the copper deposition rack, and then lift it through each process in sequence through the gantry frame. 2. Using horizontal processing lines: Horizontal processing lines, that is, each processing trough is designed as a horizontal transportation mode, arranged from front to back according to the process, and the board to be processed is placed in the horizontal line, and the board to be processed is processed in sequence through the transmission roller to complete the processing.

[0003] These two processing methods have the following disadvantages:

[0004] 1. Gantry processing line: Although the number of boards processed at one time is large, it requires more manual operation and handling times, which has a high labor cost and is harmful to the human body. In addition, the cylinder body is single, the utilization rate is low, the equipment cost is high, and the maintenance is more complicated. In addition, the gantry processing line has an overall wide body, which is time-consuming and labor-intensive to install, and occupies a large space, which is not conducive to saving resources.

[0005] 2. Although the horizontal processing line is easy to manufacture, the process control is difficult, and because the processing requires a long time to react, the horizontal line produces boards one by one, which is inefficient and affects the delivery time of the product.

[0052] Working principle: This design process is attached Figure 5 :

[0053] The key technical points of this process include:

[0054] 1. The overall processing device is divided into three parts: horizontal board inlet + pre-processing part; vertical board + upper board part; reaction tank part (overhead crane distribution); horizontal board + lower board part; horizontal post-processing + board receiving part; empty frame transfer part;

[0055] Among them, the horizontal board input + pre-processing part and the horizontal post-processing + board receiving part are realized inversely with the same technical method;

[0056] The vertical plate + upper plate part and the horizontal plate + lower plate part are realized in the same technical way in reverse order;

[0057] 2. The overall design idea is: independent horizontal board entry and pre-treatment, through the vertical board device, the independent board is changed from horizontal to vertical; then through the upper board device, the vertical boards are inserted into the board frame one by one; then transported to the front for inspection, and then transported back to the board entry section after inspection; then through the overhead crane, the board frame with the assembled processing boards is transferred to the corresponding reaction tank for processing; after completion, the board frame with the reaction is transferred to the lower board section through the overhead crane; then transported to the rear for inspection, and then transported back to the lower board section after inspection; through the lower board device, the boards in the board frame are pulled out of the board frame one by one and placed on the horizontal board device; the horizontal board device changes the vertical board to horizontal, and then transported horizontally for post-processing and board output.

[0058] 3. An empty frame transfer section is also provided, that is, after the lower plate section has extracted all the plates in the plate frame, the empty frames can be cleaned and transferred by the empty frame transfer section to the upper plate section, so as to form a return utilization of the empty frames; wherein the empty frame temporary storage section is provided to prevent "traffic jam" in the empty frame transfer.

[0059] 4. The temporary storage section of the reaction tank is used for storing the board frame of the assembled boards to be put into the reaction tank, buffering the pressure of the reaction tank and preventing the reaction tank from being jammed during processing; temporary storage ② is used for storing the boards that fall out of the reaction tank after the reaction is completed, buffering the pressure of the board receiving section and preventing the board from being jammed.

[0060] 5. The vertical plate + upper plate part, the reaction tank part (overhead crane distribution), and the horizontal plate + lower plate part are set up in a closed room, and this part of the processing process is completed in the closed room.

[0061] 6. The insert plate frame is a basket frame structure with multiple insert plate grids and two inverted triangle frame handles in the middle of the uppermost part.

[0062] 7. The overall equipment structure is as shown in the attached Figure 1 (Main view), Attachment Figure 2 (Top view) as shown.

[0063] 8. Among them, the structure of the vertical plate + upper plate is as shown in the attached Figure 3 , Attachment Figure 4 and attached Figure 6 As shown: the design method of transmission + vertical plate transmission + steering + plug-in board realization + plug-in board frame stepping + transportation is adopted;

[0064] Vertical plate transmission process: The vertical plate transmission section is divided into the middle transmission roller and the vertical plate transmission roller, which are independently set, wherein the middle transmission roller is a single-row transmission roller (i.e., only the lower transmission roller, no upper transmission roller), and the vertical plate transmission roller is an upper and lower double-row transmission roller, and the middle transmission roller and the lower row transmission roller of the vertical plate transmission roller are on the same horizontal plane;

[0065] Steering process: When the board is transmitted to the middle part of the vertical plate transmission roller, the baffle receives the signal and rises under the action of the air cap to block the board. At the same time, the roller stops transmitting. The vertical plate transmission roller, under the rotation and support of the rotating shaft, changes from horizontal to vertical with the board;

[0066] The process of inserting the board: When the board becomes vertical, the board crane receives a signal, lowers the board clamp, and clamps the vertical board. At this time, the baffle plate receives a signal and retracts under the action of the air cap. The board crane receives a signal and slowly lowers the clamped board and inserts it into the board frame directly below.

[0067] The stepping process of the board frame: the board frame is placed directly below the vertical board transmission roller and the board crane, and is placed on the stepping roller. A positioning piece is set on the side edge of the board frame, and a positioning sensor is set on the side of the stepping roller. When the board frame is placed on the stepping roller, the positioning sensor is positioned to the positioning piece, so that an inner board grid of the board frame is on the same horizontal plane as the vertical board, ensuring that the board crane can accurately insert the board into the board grid; after inserting a board, the stepping roller moves one grid inward, and then aligns the second board grid with the vertical board; and so on, the board insertion is completed.

[0068] Transportation implementation process: After the board frame is filled with a frame of boards, the transport crane receives the signal and drops the board frame out of the frame section for the next processing step.

[0069] The design of the horizontal plate + lower plate portion is the same as the design of the vertical plate + upper plate portion, that is, the reverse operation mode of the vertical plate + upper plate portion.

[0070] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
