Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of circuit board manufacturing equipment, in particular to circuit board copper deposition equipment. Background Art
[0002] Copper plating on circuit boards is a process used to make circuit boards conductive. Conductive copper layers are usually deposited on circuit boards by chemical methods or electroplating methods. The presence of the copper layer allows current to flow freely on the circuit board, connecting various electronic devices and circuit elements, thereby achieving normal operation of the circuit. In addition, the copper layer also has good thermal conductivity, which can help dissipate heat and maintain the stability and reliability of the circuit board.
[0003] At present, in the process of circuit board conduction, it is necessary to use structures such as hanging baskets or hanging plates to suspend the circuit board in chemical liquid. Once the copper plating process is completed, the circuit board needs to be removed from the hanging basket and drained. However, there is a problem in this process. When the circuit board is lifted from the treatment liquid, a large amount of liquid will be attached to the hanging basket and the circuit board. Although most hanging baskets have a drainage function, their function is relatively limited and cannot effectively guide the discharge direction of the liquid. This causes the liquid in the upper hanging basket to drip into the lower hanging basket, which not only slows down the drainage speed of the bottom circuit board, but also the bottom circuit board is in contact with the treatment liquid for a longer time, which may cause quality changes. Therefore, it is necessary to improve the design of the hanging basket to improve the drainage efficiency and ensure the consistency of the quality of each layer of circuit boards. Utility Model Content

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.
[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0025] Example
[0026] Combination Figure 1 and Figure 3 The utility model provides a technical solution: comprising an adjustment mechanism 1, the adjustment mechanism 1 is composed of a column 11 and a matching column 12, and a containing mechanism 2 is equidistantly arranged between the column 11 and the matching column 12;
[0027] The column 11 and the matching column 12 are both configured as hollow structures. The interior of the column 11 and the matching column 12 are equidistantly connected to the connecting shaft 13. The outside of the connecting shaft 13 and the interior of the column 11 are fixedly connected to the gear 14. The interior of the column 11 and the outside of the corresponding gear 14 are rotatably connected to the adjusting rod 15. The outside of the adjusting rod 15 is equidistantly provided with external threads. The outside of the adjusting rod 15 is equidistantly connected to the toothed plate 16 through the external threads. The toothed plate 16 is slidably connected to the inner wall of the column 11, and the toothed plate 16 is meshed with the corresponding gear 14.
[0028] Based on the above statements and supplements, the following principles are explained:
[0029] The containing mechanism 2 is equidistantly arranged between the column 11 and the matching column 12. Therefore, there can be multiple containing mechanisms 2, so that the device can also form a multi-layer structure. The adjusting rod 15 inside the column 11 can drive the tooth plate 16 to move down or up when rotating. Because the tooth plate 16 cannot rotate, it will mesh with the gear 14 when moving, thereby driving the gear 14 to rotate;
[0030] Combination Figure 4 and Figure 5 , the containing mechanism 2 is composed of a placing box 21, two clamping blocks 24 and a locking plate 27;
[0031] A water leakage slot 22 is provided inside the placement box 21, one side of the water leakage slot 22 is communicated with the outside, a strip-shaped water leakage slot 23 is provided equidistantly between the bottom of the inner wall of the placement box 21 and the top of the water leakage slot 22, and the water leakage slot 22 is communicated with the bottom of the inner wall of the placement box 21 through the strip-shaped water leakage slot 23;
[0032] Based on the above statements and supplements, the following principles are explained:
[0033] The strip-shaped drain groove 23 guides all the dripping and excess treatment liquid into the drain groove opening 22. Since one side of the drain groove opening 22 is connected to the outside, the excess treatment liquid can be discharged through the drain groove opening 22.
[0034] Combination Figure 4 and Figure 5 The two clamping blocks 24 are symmetrically fixedly connected to the inside of the placement box 21 and are located outside the strip-shaped water leakage groove 23. The two clamping blocks 24 are equidistantly provided with through clamping grooves on the sides close to each other.
[0035] Based on the above statements and supplements, the following principles are explained:
[0036] The clamping block 24 can clamp multiple circuit boards and leave a sufficient gap between two adjacent circuit boards, and the position clamped by the clamping block 24 is the edge of the circuit board, so it will not affect the copper plating treatment on the surface of the circuit board. In addition, the clamping block 24 is not provided with a locking or clamping structure. The material of the clamping block 24 itself can be set to a rubber material, and the size of its clamping groove is slightly smaller than the thickness of the circuit board, so that the clamping can be achieved through its own elasticity. Because the material is not within the scope of protection of the utility model, it is mentioned here only to better understand the clamping logic of the clamping block 24, so no more details are given;
[0037] Combination Figure 4 A through groove 25 is provided on one side of the placement box 21 away from the water leakage notch 22, and a locking groove 26 is provided inside the placement box 21 and outside the through groove 25, and the top of the locking groove 26 extends to the top of the placement box 21 and communicates with the outside;
[0038] Based on the above statements and supplements, the following principles are explained:
[0039] The through slot 25 is used to place the circuit board. The width of the through slot 25 needs to be larger than the width between the two clamping blocks 24, and the width and depth of the locking slot 26 must be larger than the width and depth of the through slot 25. Based on this, the through slot 25 and the locking slot 26 can achieve their respective functional effects.
[0040] Combination Figure 4 The lock plate 27 is slidably connected to the inside of the lock slot 26, and the top of the lock plate 27 is fixedly connected to the baffle plate 28. The inside of the baffle plate 28 and the top of the placement box 21 are symmetrically provided with fixing holes for matching use;
[0041] Based on the above statements and supplements, the following principles are explained:
[0042] After the circuit board is placed, the locking plate 27 is inserted into the locking groove 26, and a screw or a pin can be inserted into the fixing hole to limit the locking plate 27;
[0043] Combination Figure 1 and Figure 2 , the ends of the two corresponding connecting shafts 13 that are close to each other extend to the outside of the column 11 and the matching column 12 respectively and are fixedly connected to the outside of the corresponding placement box 21;
[0044] Based on the above statements and supplements, the following principles are explained:
[0045] The connecting shaft 13 is connected to the placement box 21, so that the placement box 21 is fixed and can also rotate by rotating the corresponding connecting shaft 13, so that the placement box 21 can achieve the purpose of adjusting the angle;
[0046] Combination Figure 1 and Figure 2 The tops of the upright column 11 and the matching column 12 are fixedly connected with a lifting ear 17, and the top of the adjusting rod 15 extends to the top of the upright column 11 and is fixedly connected with an adjusting knob 18;
[0047] Based on the above statements and supplements, the following principles are explained:
[0048] The lifting lug 17 is used to connect with an external lifting device, and the adjusting knob 18 is convenient for the staff to control the adjusting rod 15.
[0049] Working principle:
[0050] In combination with the above content, the use of the device is as follows: first, the lifting ear 17 is used to connect the device to the external lifting device so that the device is fixed, and then the circuit board is inserted into different clamping grooves in turn to fix the circuit board. The adjustment knob 18 is used to control the rotation of the adjustment rod 15, and then the meshing relationship between the tooth plate 16 and the gear 14 drives the connecting shaft 13 to rotate, so that the placement box 21 is adjusted to a horizontal position, and the locking plate 27 is placed in the locking groove 26. After being fixed, the device can be sunk into the processing liquid, and after the process is completed, the device can be upgraded to the position. The device is lifted up, and the staff rotates the adjustment rod 15 again to rotate the placement box 21, and then rotates the side of the leakage slot 22 that is connected to the outside to the low point. At this time, the liquid inside the placement box 21 will flow into the leakage slot 22 through the strip leakage groove 23 and be discharged. In addition, the bottom of the placement box 21 drives the liquid to move to the low point of the placement box 21 due to the change in angle to complete the dripping. Through the above-mentioned technical means, the problem of slow circuit board drainage efficiency caused by the dripping of the processing liquid can be greatly reduced, and the consistency of the circuit board processing effect can be effectively improved.
[0051] Finally, it should be noted that the above-described embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the various embodiments of the utility model.
