Description

Technical Field

[0001] The utility model relates to the technical field of circuit board etching, in particular to an efficient circuit board etching device. Background Technique

[0002] During the production and processing of circuit boards, it is necessary to etch the circuit boards to achieve the purpose of etching. The existing etching equipment usually sprays the etching solution onto the circuit boards by spraying. For example, in the patent with the publication number "CN220307481U" and the patent name "A Circuit Board Etching Machine", when in use, the second placement plate is toggled, and three side ends of the circuit board are placed in the inner cavity of the first placement groove. Then, under the action of the spring, the second placement groove is clamped to the other side end of the circuit board. Tighten the two fastening screws to drive the pressing block to press the circuit board in the inner cavities of the first placement groove and the second placement groove, thereby playing a role in suppressing and stabilizing the circuit board. By starting the driving motor to drive the rotation of the first placement plate, the rotation of the circuit board is driven. Then, by starting the electric push rod, the liquid collecting plate is driven to approach or move away from the circuit board. According to the distance between the circuit board and the nozzle, the circuit board can be evenly subjected to alkaline etching treatment. However, the above structure still has the following problems in the actual use process:

[0003] The above structure presses the circuit board in the inner cavities of the first placement groove and the second placement groove, thereby playing a role in suppressing and stabilizing the circuit board, and sprays the etching solution on the circuit board through the nozzle to complete the etching operation. However, during use, it is necessary to separately tighten the two sets of fastening screws before starting etching, and at the same time, after etching is completed, it is necessary to separately loosen the two sets of fastening screws again to remove the circuit board. Such an operation method is not only complex but also time-consuming and laborious, greatly reducing the etching efficiency.

[0004] Therefore, we propose an efficient circuit board etching device that can well solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide an efficient circuit board etching device to solve the problem that in the current market during use, it is necessary to separately tighten the two sets of fastening screws before starting etching, and at the same time, after etching is completed, it is necessary to separately loosen the two sets of fastening screws again to remove the circuit board. Such an operation method is not only complex but also time-consuming and laborious, greatly reducing the etching efficiency as mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: An efficient circuit board etching device, including a bottom plate, and a vertical rod is welded and fixed on the upper end surface of the bottom plate;

[0007] It further includes: the upper end surface of the vertical rod is fixed to the lower end surface of the top plate, and a cylinder is fixed on the upper surface of the top plate, and the output end of the cylinder penetrates through the top plate and is fixed to the upper end surface of the lifting plate;

[0008] Two sliding rods are arranged inside the lifting plate, and the two sliding rods are elastically slidably connected to the lifting plate through return springs, and both ends of the return springs are fixed to the sliding rods and the lifting plate respectively;

[0009] The inner ends of the sliding rods are fixed to the clamping plates, and there are two clamping plates. At the same time, anti-slip pads are bonded to the inner sides of the two clamping plates, and the anti-slip pads are made of rubber material.

[0010] Preferably, a receiving groove is formed on the lower end surface of the lifting plate, and the clamping plate is arranged inside the receiving groove.

[0011] Preferably, an etching barrel is fixed on the upper surface of the bottom plate, a liquid discharge port is fixedly arranged at the rear side of the etching barrel, and a one-way valve is installed on the outer side surface of the liquid discharge port.

[0012] Preferably, a servo motor is also fixed on the upper surface of the bottom plate, a gear is fixed to the output end of the servo motor, and the outer side surface of the gear meshes with a toothed ring.

[0013] Preferably, the toothed ring is arranged on the upper end surface of the etching barrel, and the toothed ring and the etching barrel are in a sliding connection structure, and a circular flow dividing plate is fixed to the lower end surface inside the toothed ring.

[0014] Preferably, the circular flow dividing plate is arranged inside the etching barrel, and nozzles are equidistantly distributed inside the circular flow dividing plate.

[0015] Preferably, the circular flow dividing plate is connected to an external water pump assembly through a connecting pipe, and the water pump assembly is communicated with an etching liquid storage device.

[0016] Compared with the prior art, the beneficial effects of the present utility model are: this efficient circuit board etching device not only realizes the clamping of the circuit board, thereby greatly reducing the clamping and fixing time, with a simple process, but also laterally improves the etching efficiency of the circuit board. At the same time, the sprayed etching liquid can be more uniform, effectively improving the etching efficiency, and avoiding that there is a position where the etching liquid is not sprayed during the spraying process. The specific content is as follows:

[0017] By placing the circuit board between the two clamping plates and then releasing the sliding rods, the elastic force of the return springs drives the sliding rods to reset inward, so that the sliding rods drive the clamping plates fixed to their inner ends to approach the circuit board. Through the cooperation between the two clamping plates, the clamping of the circuit board is realized, thereby greatly reducing the clamping and fixing time, with a simple process, and laterally improving the etching efficiency of the circuit board;

[0018] Further, an anti-slip pad is adhesively bonded to the inner side of the clamping plate. The anti-slip pad can not only play an anti-slip role, but also play a protective role, which can avoid damaging the circuit board when the clamping plate clamps it, and has good practicability;

[0019] The air cylinder drives the lifting plate to move downward, so that the lifting plate drives the circuit board clamped on its lower end surface to move into the etching barrel. At this time, the external etching solution can be sent into the circular flow dividing plate through the connecting pipe, and then be divided by the circular flow dividing plate to the nozzles, and finally be sprayed out by the nozzles to complete the etching of the circuit board;

[0020] The servo motor drives the engaged gear ring to rotate together through the gear, so that the gear ring drives the flow dividing plate to rotate together, and then the flow dividing plate drives the fixed nozzles to rotate and spray, so that the sprayed etching solution can be more uniform, effectively improving the etching efficiency, and at the same time avoiding that there is a position where the etching solution is not sprayed during the spraying process of the etching solution;

[0021] Furthermore, the excess etching solution will be collected together by the etching barrel. When it is necessary to clean the etching solution in the etching barrel, the etching solution can be discharged only through the liquid discharge port. Description of the Drawings

Detailed Embodiment

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figures 1-6 , the present invention provides the following technical solutions:

[0031] Embodiment 1: To solve the problem in the prior art that when in use, it is necessary to separately tighten two groups of fastening screws before starting etching, and after etching is completed, it is necessary to loosen the two groups of fastening screws separately to remove the circuit board. Such an operation method is not only complicated but also time-consuming and laborious, greatly reducing the etching efficiency. Therefore, the following solution is disclosed, including a bottom plate 1, and a vertical rod 2 is welded and fixed on the upper end surface of the bottom plate 1; further including: a sliding rod 13 is arranged inside a lifting plate 12, and there are two groups of sliding rods 13, and both groups of sliding rods 13 are elastically slidably connected to the lifting plate 12 through a return spring 15, and both ends of the return spring 15 are fixed to the sliding rod 13 and the lifting plate 12 respectively; the inner end of the sliding rod 13 is fixed to a clamping plate 14, and there are two groups of clamping plates 14, and anti-slip pads 16 are bonded to the inner sides of both groups of clamping plates 14, and the anti-slip pads 16 are made of rubber material. A receiving groove is formed on the lower end surface of the lifting plate 12, and the clamping plate 14 is arranged inside the receiving groove;

[0032] By pulling one of the two groups of sliding rods 13 outwards, the driven fixed clamping plate 14 is driven to move together. Subsequently, the circuit board can be placed between the two groups of clamping plates 14. At this time, by loosening the sliding rod 13, the elastic force of the return spring 15 drives the sliding rod 13 to reset inwards, so that the sliding rod 13 drives the clamping plate 14 fixed to its inner end to approach the circuit board. Through the cooperation between the two groups of clamping plates 14, the clamping of the circuit board is realized. At the same time, the anti-slip pad 16 is bonded to the inner side of the clamping plate 14. The anti-slip pad 16 can not only play an anti-slip effect but also play a protective role, and can avoid damaging the circuit board when the clamping plate 14 clamps, with good practicability. And both the two groups of sliding rods 13 and the clamping plate 14 can be pulled. When in use, the sliding rod 13 can be pulled according to actual use requirements, with a wide range of applications, and at the same time, the etching efficiency of the circuit board is greatly improved;

[0033] Embodiment 2: Different from Embodiment 1, this embodiment facilitates the etching of the circuit board. Specifically refer to Figures 1-2, the upper end surface of the vertical rod 2 is fixed to the lower end surface of the top plate 3, and a cylinder 11 is fixed to the upper surface of the top plate 3. The output end of the cylinder 11 penetrates through the top plate 3 and is fixed to the upper end surface of the lifting plate 12;

[0034] At the same time, after the clamping is completed, only by starting the cylinder 11, the cylinder 11 can drive the lifting plate 12 to move downward, so that the lifting plate 12 drives the circuit board clamped on its lower end surface to move into the etching barrel 4. At this time, the external etching solution can be sent into the circular flow divider 8 through the connecting pipe, and then be divided by the circular flow divider 8 to the spray heads 9, and finally be sprayed out by the spray heads 9 to complete the etching of the circuit board;

[0035] Embodiment 3: Different from Embodiment 2, in this embodiment, the sprayed etching solution can be more uniform, effectively improving the etching efficiency, and at the same time avoiding that there is a position not sprayed by the etching solution during the spraying process of the etching solution. For specific reference Figures 1-2 And Figures 5-6 , an etching barrel 4 is fixed to the upper surface of the bottom plate 1, and a drain port 10 is fixedly arranged at the rear side of the etching barrel 4. A one-way valve is installed on the outer side surface of the drain port 10. A servo motor 5 is also fixed to the upper surface of the bottom plate 1, and a gear 6 is fixed to the output end of the servo motor 5. The outer side surface of the gear 6 meshes with a gear ring 7. The gear ring 7 is arranged on the upper end surface of the etching barrel 4, and a sliding connection structure is formed between the gear ring 7 and the etching barrel 4. The inner lower end surface of the gear ring 7 is fixed with a circular flow divider 8. The circular flow divider 8 is arranged inside the etching barrel 4, and spray heads 9 are equally spaced on the inner side of the circular flow divider 8. The circular flow divider 8 is connected to an external water pump assembly through a communicating pipe, and the water pump assembly is communicated with the etching solution storage device;

[0036] At the same time, by starting the servo motor 5, the servo motor 5 can drive the gear 6 to rotate. Through the rotation of the gear 6, the engaged gear ring 7 can be driven to rotate together, so that the gear ring 7 rotates on the upper end of the etching barrel 4. Due to the fixation between the circular flow divider 8 and the gear ring 7, the gear ring 7 will also drive the circular flow divider 8 to rotate together, so that the circular flow divider 8 drives the fixed spray heads 9 to rotate and spray, so that the sprayed etching solution can be more uniform, effectively improving the etching efficiency, and at the same time avoiding that there is a position not sprayed by the etching solution during the spraying process of the etching solution. And the excess etching solution will be collected together by the etching barrel 4. When it is necessary to clean the etching solution in the etching barrel 4, the etching solution can be discharged only through the drain port 10.
