Technical Field
[0001] This utility model belongs to the field of PCB etching technology, and specifically relates to a high-efficiency PCB etching device. Background Technology
[0002] In the field of electronic equipment manufacturing, printed circuit boards (PCBs) are crucial carriers for various electronic components, and their manufacturing quality directly affects the performance and stability of electronic devices. Etching is one of the key processes in PCB manufacturing. Etching removes unwanted copper layers, thereby forming precise circuit patterns. Traditional PCB etching processes typically use etching tanks to etch the PCB board. During etching, the PCB board needs to be placed in a specific device to ensure its stable position in the etching solution, preventing uneven etching due to movement or shaking, which would affect the accuracy and quality of the circuit pattern. Simultaneously, to improve production efficiency, the PCB board needs to be easily and quickly transferred from one process to another, requiring etching equipment with good operability and ease of handling.
[0003] Existing PCB etching equipment often uses simple fixing methods when positioning PCB boards, making it difficult to accurately fix the PCB board's position. During the etching process, the PCB board is prone to movement or shaking, resulting in uneven etching, affecting the accuracy and quality of the circuit pattern, and increasing the product defect rate. Different sizes and specifications of PCB boards require different etching equipment for positioning and etching. Most existing etching equipment is designed for specific PCB board sizes and is difficult to adapt to different sizes and specifications. Companies need to purchase multiple etching equipment of different specifications, increasing equipment procurement costs and floor space. Some etching equipment has structural design flaws, lacking stable support structures, making it prone to shaking or tilting during etching, affecting the etching effect. In addition, insufficient stability of the equipment during transportation can easily damage the PCB board.
[0004] In view of this, we propose a high-efficiency PCB etching device to solve the above problems. Utility Model Content
[0005] The present invention aims to solve the technical problem in the prior art where PCB board etching is prone to movement or shaking, and different etching devices are required for positioning and etching of PCB boards of different sizes and specifications, making it inconvenient to transport and move them.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A high-efficiency PCB etching apparatus, comprising:
[0008] An etched frame is used for the mating and positioning of the PCB board. The etched frame includes two frame uprights on both sides, an upper wide toothed frame and a lower single toothed frame on the frame uprights with adjustable position; the top of the PCB board is located between the two upper wide toothed frames on both sides and is located in tooth groove A, and the bottom of the PCB board is limited and placed on the lower single toothed frame and is located in tooth groove B.
[0009] The Y-shaped handle engages with the two frame uprights for guidance and is used to assist the human hand in lifting and transferring the etched frame.
[0010] Preferably, the frame uprights are provided with two layers of limiting guide grooves arranged at equal intervals, which respectively cooperate with the upper wide tooth frame and the lower single tooth frame for limiting and guiding sliding.
[0011] As a preferred option, several weight-reducing holes are arranged at equal intervals on the frame uprights.
[0012] Preferably, the upper wide gear frame includes a round rod A, two sets of racks A arranged horizontally and symmetrically on both sides of the round rod A, two sliders A fixed at both ends of the round rod A and cooperating with the limiting guide groove for limiting and guiding sliding, external thread rods A fixed on the outer sides of the two sliders A respectively, and a locking knob A threadedly connected to the external thread rods A from the outside of the frame upright plate and locking the upper wide gear frame to the two frame upright plates.
[0013] Gap A is formed between two adjacent teeth on rack A.
[0014] Preferably, the lower single tooth frame includes a round rod B, a rack B perpendicular to the round rod B, two sliders B fixed at both ends of the round rod B and cooperating with the limiting guide groove for limiting and guiding sliding, an external thread rod B fixed on the outer side of the two sliders B respectively, and a locking knob B threaded from the outside of the frame upright plate to the external thread rod B and locking the lower wide tooth frame to the two frame upright plates.
[0015] Gap B is formed between two adjacent teeth on rack B.
[0016] Preferably, the tops of both frame uprights are folded outwards and equipped with E-shaped guide rails, and the bottoms of both sides of the Y-shaped handles are equipped with guide grooves that cooperate with the E-shaped guide rails for sliding.
[0017] Preferably, the bottom of the frame uprights is provided with horizontal supports.
[0018] As a preferred option, the top of the Y-shaped handle is equipped with a handle ring.
[0019] Compared with the prior art, the technical effects and advantages of this utility model are:
[0020] This high-efficiency PCB etching device uses an upper wide-tooth frame and a lower single-tooth frame to accurately insert and position the PCB board, effectively preventing movement or shaking during the etching process. This ensures etching precision and quality, improving the PCB board yield. The Y-shaped handle design, combined with the etching frame, allows operators to quickly lift and transfer the entire etching frame, reducing the time and difficulty of manual handling and greatly improving work efficiency.
[0021] The limiting guide grooves on the frame uprights allow for flexible adjustment of the positions of the upper wide toothed frame and the lower single toothed frame, enabling them to adapt to PCB boards of different sizes and specifications. This enhances the versatility and applicability of the device and reduces the equipment procurement costs for enterprises.
[0022] The horizontal supports at the bottom of the frame stand provide stable support for the etching frame, ensuring the device remains stable during etching and preventing swaying or tilting from affecting the etching effect. Meanwhile, the coordinated design of the E-type guide rail and guide groove ensures stability during lifting with the Y-type handle. The ergonomically designed handle loop at the top of the Y-type handle allows operators to easily grip and lift the etching frame, improving operational convenience and comfort, and reducing operator workload.
[0023] The weight-reducing holes on the frame uprights reduce the overall weight of the etching frame without compromising structural strength, making it easier for operators to handle and operate. Furthermore, the design of these weight-reducing holes also lowers the manufacturing cost of the device.
[0024] The upper wide-tooth frame's toothed groove A precisely clamps the top of the PCB board, while the lower single-tooth frame's toothed groove B provides reliable support and restraint for the bottom of the PCB board, further ensuring the stability of the PCB board during the etching process. This upper wide-tooth and lower single-tooth design prevents liquid from accumulating on the etching frame, facilitating the flow and renewal of the etching solution, ensuring uniform etching results, and reducing the adverse effects of liquid residue on the PCB board.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] The following combination Figures 1 to 6 This application will be described in further detail.
[0034] This application discloses an efficient PCB etching device, including an etching frame 1 for positioning and interlocking the PCB board and a Y-shaped handle 2.
[0035] The etching frame 1 is used for the mating and positioning of the PCB board. The etching frame 1 includes two frame uprights 11 on both sides, an upper wide toothed frame 12 and a lower single toothed frame 13 on the frame uprights 11 with adjustable position; the top of the PCB board is located between the two upper wide toothed frames 12 on both sides and is located in the toothed groove A1201, and the bottom of the PCB board is limited and placed on the lower single toothed frame 13 and is located in the toothed groove B1301.
[0036] The Y-shaped handle 2 is engaged with the two frame uprights 11 for guidance and insertion, and is used to assist the human hand in lifting and transferring the etched frame 1.
[0037] The etching frame 1 uses the upper wide toothed frame 12 and the lower single toothed frame 13 to cooperate and position the PCB board, which can accurately fix the position of the PCB board and prevent the PCB board from moving or shaking during the etching process, thereby ensuring the accuracy and quality of etching.
[0038] The Y-shaped handle is engaged with the two frame uprights 11 for guidance and insertion, making it convenient for operators to lift and transfer the etched frame 1 as a whole through the handle ring 202, which improves work efficiency and reduces the risk of damage to the PCB board during manual handling.
[0039] The frame upright plate 11 has two layers of limiting guide grooves 1101 arranged at equal intervals, which respectively cooperate with the upper wide toothed frame 12 and the lower single toothed frame 13 for limiting, guiding and sliding. The bottom of the frame upright plate 11 is provided with horizontal support feet 1103. Several weight reduction holes 1102 are arranged at equal intervals on the frame upright plate 11.
[0040] The frame plate 11 has two layers of limiting guide grooves 1101 arranged at equal intervals, which respectively cooperate with the upper wide toothed frame 12 and the lower single toothed frame 13 for limiting, guiding and sliding. This allows the upper wide toothed frame 12 and the lower single toothed frame 13 to be flexibly adjusted in position on the frame plate 11 to adapt to PCB boards of different sizes and specifications, thereby enhancing the versatility and applicability of the device.
[0041] The bottom of the frame plate 11 is provided with a horizontal support foot 1103, which can provide stable support for the etching frame 1, ensuring that the device remains stable during the etching process and avoiding the etching effect due to shaking or tilting.
[0042] The frame plate 11 has several weight-reducing holes 1102 arranged at equal intervals. Without affecting the structural strength of the frame plate 11, the weight of the entire etching frame 1 is effectively reduced, making it easier for operators to handle and operate, and also reducing manufacturing costs.
[0043] The upper wide gear frame 12 includes a round rod A1202, two sets of racks A1203 horizontally and symmetrically arranged on both sides of the round rod A1202, two sliders A1204 fixed at both ends of the round rod A1202 and cooperating with the limiting guide groove 1101 for limiting and guiding sliding, external thread rods A1205 respectively fixed on the outer side of the two sliders A1204, and locking knobs A1206 threaded from the outside of the frame upright plate 11 to the external thread rods A1205 and locking the upper wide gear frame 12 to the two frame upright plates 11; the tooth groove A1201 is formed between two adjacent teeth on the rack A1203.
[0044] The lower single-tooth frame 13 includes a round rod B1302, a rack B1303 perpendicular to the round rod B1302, two sliders B1304 fixed at both ends of the round rod B1302 and cooperating with the limiting guide groove 1101 for limiting and guiding sliding, external thread rods B1305 respectively fixed on the outer side of the two sliders B1304, and a locking knob B1306 threaded from the outside of the frame upright plate 11 to the external thread rods B1305 and locking the lower wide tooth frame onto the two frame upright plates 11; the tooth groove B1301 is formed between two adjacent teeth on the rack B1303.
[0045] A tooth groove A is formed between two adjacent teeth on the rack A of the upper wide tooth frame 12. The top of the PCB board is located between the two upper wide tooth frames 12 on both sides and inside the tooth groove A, which can accurately clamp the top of the PCB board and prevent the PCB board from wobbling left and right during the etching process.
[0046] By cooperating with the slider A and the limiting guide groove 1101, the upper wide tooth frame 12 can slide and adjust its position on the frame upright plate 11. After adjustment, the upper wide tooth frame 12 is locked and fixed on the two frame upright plates 11 by the threaded connection between the locking knob A and the external thread rod A, ensuring the stability of its position.
[0047] A tooth groove B is formed between two adjacent teeth on the rack B of the lower single tooth frame 13. The bottom end of the PCB board is placed on the lower single tooth frame 13 and located in the tooth groove B, which provides reliable support and limitation for the bottom end of the PCB board, further ensuring the stability of the PCB board during the etching process.
[0048] Similar to the upper wide toothed frame 12, the lower single toothed frame 13 achieves position adjustment through the cooperation of slider B and limit guide groove 1101, and achieves position locking through the threaded connection of locking knob B and external thread rod B, so as to adapt to PCB boards of different sizes.
[0049] Furthermore, the design of a wide tooth on the upper layer and a single tooth on the lower layer prevents liquid from accumulating on the etched frame 1.
[0050] Both frame uprights 11 have E-shaped guide rails 1104 that fold outwards at their top ends. The bottom ends of the Y-shaped handles 2 have guide grooves 201 that slide smoothly along the E-shaped guide rails 1104. This allows the Y-shaped handles to slide smoothly along the E-shaped guide rails, facilitating connection and separation from the etched frame 1, while also ensuring stability during lifting. The top of the Y-shaped handle 2 has a handle ring 202. The handle ring 202 is ergonomically designed, allowing operators to easily grip the handle ring 202 to lift and transfer the etched frame 1, improving operational convenience and comfort.
[0051] In this high-efficiency PCB etching device, the operator adjusts the positions of the upper wide toothed frame 12 and the lower single toothed frame 13 by sliding sliders A and B within the limiting guide groove 1101 according to the size of the PCB board. After adjustment, locking knobs A and B are tightened to fix the upper wide toothed frame 12 and the lower single toothed frame 13 onto the frame upright plate 11. Then, the top end of the PCB board is inserted into the tooth grooves A of the upper wide toothed frames 12 on both sides, and the bottom end is placed in the tooth grooves B of the lower single toothed frame 13, achieving accurate insertion and positioning of the PCB board within the etching frame 1.
[0052] Align the guide grooves 201 at the bottom of both sides of the Y-shaped handle with the E-shaped guide rail at the top of the frame upright plate 11, and let the Y-shaped handle slide along the E-shaped guide rail to complete the connection with the etching frame 1. The operator holds the handle ring 202 at the top of the Y-shaped handle and lifts the etching frame 1 as a whole to realize the transfer of the device. This makes the installation, positioning and etching of the PCB board efficient and convenient, and has a wide range of applications.
[0053] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
