Description

Technical Field

[0001] This utility model relates to the technology in the field of circuit board manufacturing, and in particular to an acid etching line for circuit board manufacturing. Background Technology

[0002] Acid etching line (VCE) is short for electro-chemical vertical continuous etching line (acid), also known as nano-electro-chemical etching line. This production line is used for circuit board production. It mainly utilizes nano-electrochemical technology to precisely etch lines on circuit boards, and can etch lines as small as 5.0 nm. Its etching control mechanism is as follows:

[0003]

[0004]

[0005] The current acid etching line is mainly composed of four parts: acid etching section, first water washing section, film stripping section and second water washing section. The acid etching section, first water washing section, film stripping section and second water washing section respectively perform acid etching, first water washing, film stripping and second water washing on the circuit board.

[0006] However, in existing technologies, the acid etching section, the first water rinsing section, the stripping section, and the second water rinsing section operate independently. This requires operators to manually load and unload the circuit boards between the acid etching section and the first water rinsing section, between the first water rinsing section and the stripping section, and between the stripping section and the second water rinsing section. This method cannot achieve continuous automated production of circuit boards, resulting in low production efficiency and high labor costs. Therefore, it is necessary to research a solution to address these problems. Utility Model Content

[0007] In view of this, the present invention addresses the deficiencies of the existing technology, and its main objective is to provide an acid etching line for circuit board production, which can effectively solve the problem that existing acid etching lines cannot perform continuous automated production of circuit boards.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] An acid etching line for circuit board production includes a frame, an acid etching section, a first washing section, a stripping section, a second washing section, a conveying device, and multiple clamps. The acid etching section, the first washing section, the stripping section, and the second washing section are all disposed within the frame and arranged horizontally in sequence. The conveying device is disposed on the frame. The multiple clamps are disposed on the conveying device, and the multiple clamps are conveyed sequentially through the acid etching section, the first washing section, the stripping section, and the second washing section. Lifting and pulling devices are provided between the acid etching section and the first washing section, between the first washing section and the stripping section, and between the stripping section and the second washing section.

[0010] As a preferred embodiment, the acid etching section includes multiple etching pools that are arranged laterally and connected to each other.

[0011] As a preferred embodiment, the first washing section includes a plurality of first washing pools, which are arranged horizontally in sequence and connected to each other.

[0012] As a preferred embodiment, the film removal section includes multiple film removal pools, which are arranged horizontally in sequence and connected to each other.

[0013] As a preferred embodiment, the second washing section includes a plurality of second washing pools, which are arranged horizontally in sequence and connected to each other.

[0014] As a preferred embodiment, the lifting and pulling device includes a lifting mechanism and a pulling mechanism. The lifting mechanism is mounted on the frame, and the pulling mechanism is mounted on the lifting mechanism and driven by the lifting mechanism to move up and down. The pulling mechanism drives the clamp to move laterally.

[0015] As a preferred embodiment, the conveying device is a chain-type conveying device, which includes a conveying chain and a conveying motor. The conveying chain is rotatably mounted inside the frame and includes a lower section and an upper section. The lower section is located beside the acid etching section, the first water washing section, the film stripping section, and the second water washing section, and the upper section is located above the lower section. The conveying motor is mounted on the frame and drives the conveying chain to operate.

[0016] As a preferred embodiment, the clamp is an electric clamp.

[0017] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

[0018] By having multiple fixtures sequentially pass through an acid etching section, a first water washing section, a film stripping section, and a second water washing section via a conveyor device, and by installing lifting and pulling devices between the acid etching section and the first water washing section, between the first water washing section and the film stripping section, and between the film stripping section and the second water washing section, the fixtures can be automatically moved using these lifting and pulling devices.

[0041] The acid etching section 21, the first water washing section 22, the film stripping section 23, and the second water washing section 24 are all disposed within the frame 10 and arranged horizontally in sequence. Specifically, the acid etching section 21 includes multiple etching pools 211, which are arranged horizontally in sequence and connected. The first water washing section 22 includes multiple first water washing pools 221, which are arranged horizontally in sequence and connected. The film stripping section 23 includes multiple film stripping pools 231, which are arranged horizontally in sequence and connected.

The specific structure and working principle of each etching pool 211, the first washing pool 221, the stripping pool 231 and the second washing pool 241 are existing technologies. The specific structure and working principle of each etching pool 211, the first washing pool 221, the stripping pool 231 and the second washing pool 241 will not be described in detail here.

[0042] The conveying device 30 is mounted on the frame 10. In this embodiment, the conveying device 30 is a chain-type conveying device. Specifically, the conveying device 30 includes a conveying chain 31 and a conveying motor 32. The conveying chain 31 is rotatably mounted inside the frame 10. The conveying chain 31 includes a lower section 311 and an upper section 312. The lower section 311 is located beside the acid etching section 21, the first water washing section 22, the film stripping section 23, and the second water washing section 24. The upper section 312 is located above the lower section 311. The conveying motor 32 is mounted on the frame 10 and drives the conveying chain 31 to operate.

[0043] The multiple clamps 40 are mounted on the conveying device 30, and the multiple clamps 40 pass sequentially through the acid etching section 21, the first water washing section 22, the film removal section 23, and the second water washing section 24. In this embodiment, as... Figure 5 As shown, the clamp 40 is an electric clamp, and its specific structure and working principle are existing technologies. The specific structure and working principle of the clamp will not be described in detail here.

[0044] Furthermore, lifting and pulling devices 50 are provided between the acid etching section 21 and the first water washing section 22, between the first water washing section 22 and the film removal section 23, and between the film removal section 23 and the second water washing section 24. Each lifting and pulling device 50 includes a lifting mechanism 51 and a pulling mechanism 52. The lifting mechanism 51 is mounted on the frame 10 and can be a cylinder or other similar mechanism, without limitation. The pulling mechanism 52 is mounted on the lifting mechanism 51 and is driven by the lifting mechanism 51 to move up and down. The pulling mechanism 52 also drives the clamp 40 to move laterally. Specifically, for example... Figure 6 and Figure 7 As shown, the pulling mechanism 52 includes a support frame 521, a transmission chain 522, a motor 523, and a slide rod 524. The support frame 521 is installed and connected to the lifting mechanism 51. The transmission chain 522 is rotatably mounted on the support frame 521. The motor 523 is fixed to the support frame 521 and drives the transmission chain 522 to rotate. The slide rod 524 is slidably mounted on the support frame 521 and is fixedly connected to the transmission chain 522. The reciprocating rotation of the transmission chain 522 drives the slide rod 524 to move back and forth laterally. The slide rod 524 is slidably mounted on the support frame 521. The slide rod 524 is fixedly connected to the transmission chain 522. The reciprocating rotation of the transmission chain 522 drives the slide rod 524 to move back and forth laterally. The slide rod 524 faces forward (e.g., when the transmission chain 522 rotates back and forth). Figure 6 ) or facing backward (such as Figure 7 This allows for forward or backward dragging.

[0045] The working principle of this embodiment is described in detail below:

[0046] During operation, the control cabinet 60 controls the acid etching section 21, the first water washing section 22, the film removal section 23, the second water washing section 24, and the conveying device 30. First, the circuit board 70 to be processed is clamped and fixed by the fixture 40. The fixtures 40 holding the circuit board 70 are placed one by one on the conveying device 30, and the conveying device 30 conveys each fixture 40 sequentially, so that the circuit board 70 on the fixture 40 passes through the acid etching section 21, the first water washing section 22, the film removal section 23, and the second water washing section 24 in sequence. To facilitate the automatic completion of acid etching, first water wash, film removal, and second water wash operations on the circuit board 70, specifically, when the circuit board 70 moves to the end of the acid etching section 21, the corresponding lifting and pulling device 50 lifts the corresponding clamp 40, pulls the clamp 40 forward, and then places the clamp 40 back onto the conveyor 30. In this way, the circuit board 70 is lifted, pulled forward, and lowered along with the clamp 40, thus placing the circuit board 70 into the first water wash section 22. Similarly, when the circuit board 70 moves to the end of the first water wash section 22, the end of the film removal section 23, and the end of the second water wash section 24, the corresponding lifting and pulling devices 50 place the circuit board 70 into the film removal section 23, the second water wash section 24, and the output section 24, respectively, using the same principle. When the circuit board 70 completes its second washing and is output, it is removed from the fixture 40, and then the empty fixture 40 is returned from the upper section 312 to the front end of the production line by the conveyor device 30. It should be noted that the circuit board 70 can be loaded and unloaded manually or by a robot at the front and back ends of the production line, without limitation.

[0047] The key design feature of this invention is that multiple fixtures are sequentially transported through an acid etching section, a first water washing section, a film stripping section, and a second water washing section via a conveying device. Lifting and pulling devices are installed between the acid etching section and the first water washing section, between the first water washing section and the film stripping section, and between the film stripping section and the second water washing section. These lifting and pulling devices automatically move the fixtures, thereby achieving automatic loading and unloading of circuit boards without manual operation. This allows for continuous automated production of circuit boards, effectively improving production efficiency, reducing labor costs, and bringing convenience to production operations.

[0048] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
