Description

Technical Field

[0001] This utility model relates to the field of etching equipment technology, specifically to a precision etching device with multi-pipeline real-time monitoring and automatic compensation. Background Technology

[0002] Printed circuits are electronic circuits that connect electronic components to each other. The typical process for printing circuit manufacturing is the "subtractive process," which involves first processing a resist layer, such as a photosensitive film or photosensitive ink, on the copper foil portion of the board that needs to be retained, i.e., the patterned portion of the circuit. Then, the non-patterned copper foil is etched away using chemical methods, also known as etching. Currently, spray-type precision etching equipment is widely used. It processes the substrate of the printed circuit board through spray etching, which has high etching precision and can effectively meet the production requirements of printed circuits.

[0003] Currently, the etching accuracy of precision etching equipment is affected by factors such as the stability of the chemical concentration and the uniformity of the chemical spray. Conventional etching spray design involves multiple chemical spray pipes in the etching tank, connected to standard etching nozzles. These nozzles use the same spray pressure and flow rate conditions to complete the etching of the main body of the product. A set of independently adjustable nozzles for uniformity adjustment is installed at the tail of the etching tank. During uniformity adjustment, sample testing is first used to determine the product's dimensional fluctuations. Then, the spray pressure and flow rate at the corresponding location are increased or decreased, and the sample dimensions are tested again. This process is repeated until the product's dimensional uniformity meets the requirements. Chemical stability can be ensured through automatic measurement and compensation using an online automatic analyzer. However, chemical spraying currently commonly relies on manual sample testing and manual adjustment of the spray flow rate / pressure. This approach has the following problems:

[0004] 1. Poor operability; manual sample testing by personnel is time-consuming and labor-intensive.

[0005] 2. Manual adjustment relies on personnel experience, resulting in low accuracy and a high risk of errors.

[0006] 3. The equipment cannot be monitored online in real time, and abnormalities in the spraying accuracy cannot be detected in time, which can easily lead to batch defects.

[0007] Therefore, it is of great importance to design a precision etching device with multi-pipeline real-time monitoring and automatic compensation to solve the above-mentioned defects. Utility Model Content

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0015] As a preferred embodiment of this utility model, the nozzle has multiple sets of spray holes on its outer side, and the diffuser cover has guide grooves at positions corresponding to the multiple sets of spray holes.

[0016] As a preferred embodiment of this utility model, electric push rods are fixedly installed on the outer sides of multiple sets of spray pipes, and the driving end of the electric push rods is fixedly connected to the rear end of the adjusting sleeve through a connecting frame.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0030] Example: Please refer to Figures 1-7 This utility model provides a technical solution:

[0031] A precision etching device with multi-pipeline real-time monitoring and automatic compensation includes a spray frame 1. Multiple sets of spray pipes 2 are rotatably connected to the inner side of the spray frame 1. Multiple sets of etching spray pipes 3 are fixedly connected to the outer side of each set of spray pipes 2. Adjustment sleeves 4 are fitted on the outer side of each set of etching spray pipes 3. Electronic instruments 5 are fixedly installed at the left end of each set of spray pipes 2. Electronic valves 6 are installed at the connection between each set of etching spray pipes 3 and spray pipes 2. A monitoring host 7 is fixedly installed on the top of the spray frame 1. The multiple sets of electronic instruments 5 and electronic valves 6 are electrically connected to the monitoring host 7. An angle adjustment component 8 is fixedly installed on the left side of the spray frame 1.

[0032] First, the spray frame 1 is fixedly installed on the spray etching production line. During spray etching, each spray pipe 2 is equipped with an electronic instrument 5 at its left end. The electronic instrument 5 can be an electronic pressure gauge, an electronic flow meter, or a combination of both. During production, parameters can be collected in real time and uploaded to the monitoring host 7. After obtaining the parameter data of each spray pipe 2, the monitoring host 7 uses a pre-set algorithm to calculate the required adjustment amount for each pipe. The nozzles used for etching uniformity compensation no longer require manual adjustment. Each spray pipe 2 is equipped with an electronic valve 6. The electronic valve 6 automatically adjusts the spray pressure and flow rate according to the instructions of the monitoring host 7, thereby completing the automatic compensation adjustment of etching spray uniformity. No manual operation is required, and the speed and efficiency are high. Since the equipment automatically adjusts according to the pre-set algorithm, it does not rely on human experience and has high adjustment accuracy. At the same time, online real-time monitoring is achieved. When the equipment spray accuracy is abnormal, it can immediately and automatically compensate and issue an alarm, which can avoid batch defects.

[0033] Furthermore, in this embodiment, the specific structure of the angle adjustment component 8 is as follows:

[0034] The angle adjustment assembly 8 includes an adjustment motor 801 fixedly installed on the left side of the spray frame 1. Connecting sleeves 802 are fixedly connected to the left ends of multiple sets of spray pipes 2. Transmission arms 803 are fixedly installed on the outer sides of the multiple sets of connecting sleeves 802. The multiple sets of transmission arms 803 are connected to each other via a synchronizing rod 804. A driving block 805 is fixedly installed on the drive end of the adjustment motor 801. The left side of the synchronizing rod 804 is rotatably connected to the transmission arms 803 and the driving block 805 via multiple sets of connectors 806. During the spray etching process, the adjustment motor 801 drives the driving block 805 to rotate. Under the transmission of the synchronizing rod 804, the multiple sets of transmission arms 803 can be driven to swing together simultaneously. This allows for the simultaneous adjustment of the spray angle of the multiple sets of spray pipes 2 according to the etching operation requirements, avoiding the problem of insufficient etching in dead angles and further ensuring production quality.

[0035] Furthermore, the regulating motor 801 is fixedly connected to the spray frame 1 via the mounting bracket 807. Multiple sets of transmission arms 803 and the inner side of the drive block 805 are all threaded with fixing screws 808. The regulating motor 801 is installed on the left side of the spray frame 1 via the mounting bracket 807. The drive block 805 and the drive end of the regulating motor 801 are fixed by the fixing screws 808. At the same time, the left ends of multiple sets of spray pipes 2 are fixedly connected to the transmission arms 803 via fixing screws 808, which facilitates assembly and disassembly.

[0036] Then, the left and right ends of the multiple sets of spray pipes 2 are rotatably connected to the spray frame 1 through bearings 201. The right end of the multiple sets of spray pipes 2 is fixedly connected to a liquid guiding hose 202. Under the connection of the bearings 201, the spray pipes 2 can rotate inside the spray frame 1, thereby adjusting the spray angle. The liquid guiding hose 202 is used to introduce the etching solution and can be adjusted as the spray pipes 2 rotate.

[0037] Furthermore, each of the multiple sets of etching nozzles 3 is fixedly connected to a nozzle 301 at its front end. A diffuser 302 is fixedly connected to the front end of the nozzle 301. A baffle 303 is threadedly connected to the front end of the nozzle 301 and inside the diffuser 302. The etching liquid is sprayed out through the nozzle 301, and the diffuser 302 is used to perform a cone-shaped diffusion of the sprayed etching liquid. The baffle 303 reduces the range to prevent the etching liquid from being directly sprayed.

[0038] Secondly, multiple sets of nozzles 304 are provided on the outer side of the nozzle 301. Guide grooves 305 are provided at the positions corresponding to the multiple sets of nozzles 304 on the diffuser 302. The etching solution is sprayed out through the multiple sets of nozzles 304 on the outer side of the nozzle 301, and the guide grooves 305 further guide the sprayed etching solution so that it is sprayed out and makes a cone-shaped diffusion spray after contacting the diffuser 302, thereby fully performing the etching operation.

[0039] Finally, electric push rods 401 are fixedly installed on the outer side of multiple sets of spray pipes 2. The driving end of the electric push rod 401 is fixedly connected to the rear end of the adjusting sleeve 4 through the connecting frame 402. Slider 403 is fixedly connected to the connection point of multiple sets of adjusting sleeves 4 and electric push rods 401. Multiple sliders 403 are fixedly connected to the etching spray pipe 3 through the sliding groove 404. By pushing the connecting frame 402 with the electric push rod 401, the adjusting sleeve 4 can be moved to slide on the outer side of the etching spray pipe 3 in sync. The slider 403 slides on the inner side of the sliding groove 404, which further ensures the movement stability of the adjusting sleeve 4. By adjusting the extension and retraction state of the adjusting sleeve 4, the range of etching liquid sprayed from the diffuser 302 can be adjusted. When the adjusting sleeve 4 is at the front end, the adjusting sleeve 4 completely covers the diffuser 302, making the etching liquid spray concentrated and the impact force greater. When the adjusting sleeve 4 is at the rear end, the restriction on the diffuser 302 is released. At this time, the range of etching liquid spraying is the largest, so that it can be adjusted according to the etching requirements, which further improves the practicality of the equipment.

[0040] In this embodiment, the specific implementation scenario is as follows: the spray frame 1 is fixedly installed on the spray etching production line. During spray etching, each spray pipe 2 is equipped with an electronic instrument 5 at its left end. The electronic instrument 5 can be an electronic pressure gauge, an electronic flow meter, or a combination of both. During the production process, parameters can be collected in real time and uploaded to the monitoring host 7. After obtaining the parameter data of each spray pipe 2, the monitoring host 7 uses a pre-set algorithm to calculate the required adjustment amount for each pipe. The nozzles used for etching uniformity compensation no longer require manual adjustment. Each spray pipe 2 is equipped with an electronic valve 6. The electronic valve 6 automatically adjusts the spray pressure and flow rate according to the instructions of the monitoring host 7, thereby completing the automatic compensation adjustment of etching spray uniformity. No manual operation is required, and the speed and efficiency are high. Since the equipment automatically adjusts according to the pre-set algorithm, it does not rely on human experience, and the adjustment accuracy is high. At the same time, online real-time monitoring is achieved. When the equipment spray accuracy is abnormal, it can immediately and automatically compensate and issue an alarm message, which can avoid batch defects. Moreover, the angle and range of the etching solution spray can be adjusted according to the etching requirements, further improving the practicality of the equipment.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
