Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of DPC copper plating, in particular to a novel vertical developing and etching hanger. Background Art
[0002] In the DPC copper plating process, developing and etching are crucial steps. Designing a rack that is easy to clamp and accommodates a variety of sizes, based on existing racks, is paramount. The rack provides a stable support structure, allowing the plated parts to be easily suspended in the developing or etching tank, ensuring they remain level and stable throughout the process. The rack, after being sprayed with chemical liquids, should possess sufficient mechanical strength and good corrosion resistance. It should also be lightweight, compact, durable, easy to load and unload parts, and have an appropriate loading capacity.
[0003] However, when products are placed on existing hangers, they are often clamped and fixed by hooks. When the hooks clamp and fix the products, it is inevitable that scratches and wear will be caused on the surface of the products. At the same time, existing hangers are usually suitable for fixed suspension of products of the same size, which greatly limits the size of the products. Manufacturing new hangers for different products will also increase production costs and a certain amount of time. Utility Model Content
[0004] In view of the deficiencies in the prior art, the utility model aims to provide a novel vertical developing and etching hanger.
[0005] In order to achieve the above purpose, the technical solution of the present invention is as follows:
[0006] A new type of vertical developing and etching hanger includes a frame body, grooves are provided on both sides of the frame body, baffles are provided on one side of the front left and right sides of the frame body, a threaded rod is fixed to the end of the frame body away from the rotating end of the baffle, a nut is threaded on the threaded rod and a vertical plate is provided in the frame body, and a sliding groove is provided on the side of the vertical plate facing the groove.
[0007] Preferably, the facing surfaces of the two baffles on the side where they are rotatably connected to the frame are both configured to be arc-shaped.
[0008] Preferably, stoppers are provided on the left and right sides of the front portion of the frame body respectively, and the stoppers abut against the two sides of the baffle.
[0009] Preferably, the baffle has a rotation angle of at most 90 degrees, and a rotation direction from vertical to horizontal.
[0010] Preferably, through holes slidably connected to the vertical plates are provided on both the upper and lower sides of the frame body, and bolts passing through the through holes are provided on both the upper and lower sides of the vertical plates.
[0011] Preferably, a plurality of protrusions are provided at corresponding horizontal heights in the two grooves, a plurality of slide grooves are provided on the side surface of the vertical plate, and the interval positions between the slide grooves correspond to the positions of the protrusions.
[0012] Compared with the prior art, the beneficial effects of the present invention are:
[0013] 1. The utility model provides threaded rods on both sides of the frame. The threaded rods restrict the baffle from rotating outwards of the frame during the process of cooperating with the nut threads. The arc design of the baffle rotates in coordination with the corresponding stopper of the frame. At the same time, there is also a stopper on the top of the frame, which restricts the baffle from rotating inwards. In this process, the coordination between the baffle and the frame, and the coordination between the nut and the threaded rods reduces the risk of collision when the product is placed in the frame. The ingenious coordination relationship also greatly improves the convenience of clamping.
[0014] 2. The utility model adjusts the relative position between the vertical plate and the outer rod of the frame through the sliding connection between the vertical plate and the through hole, thereby adapting to products of different sizes. While the vertical plate serves to fix and suspend the product, it can also adjust the range to adapt to products of different sizes, greatly improving the flexibility of use.

[0022] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural methods and implementation methods. Therefore, the following specific embodiments and drawings are only illustrative of the technical solution of the present invention and should not be regarded as the entire present invention or as a limitation or restriction of the technical solution of the present invention.
[0023] like Figure 1 As shown, as a new vertical developing and etching rack of the utility model, it includes a frame 1, the frame 1, the frame 1 has grooves 7 on both sides of the rear portion, the frame 1 has baffles 2 on both sides of the front portion, one side of the baffle 2 is rotatably connected to the lower portion of the frame 1, and the frame 1 has stoppers 9 on both sides of the front portion. Figure 3 As shown, the facing surfaces of the two baffles 2 and the frame 1 on one side of the rotation connection are both set to arc shape, and the stopper 9 is divided into upper and lower parts. The lower stopper 9 is set to arc shape and conflicts with the arc-shaped part of the baffle 2. The upper stopper 9 conflicts with the upper part of the baffle 2 when the baffle 2 rotates to a vertical state, as shown in FIG. Figure 2 As shown, threaded rods 4 are fixed to the ends of both sides of the upper part of the frame 1, and nuts 5 are threadedly provided on the threaded rods 4, and when the baffle 2 is rotated to a vertical state, the nuts 5 respectively contact the two sides of the baffle 2 with the stop parts 9, and the baffle 2 is rotated to seal one side of the groove 7 so that the groove 7 forms a notch with only one side open. Through the arc-shaped stop part 9 that rotates in coordination with the baffle 2, the two stop parts 9 on the frame 1 also limit the rotation direction of the baffle 2, so that the rotation angle of the baffle 2 is at most 90 degrees, and the rotation direction is vertical to horizontal; threaded rods 4 are designed on the left and right sides of the upper part of the frame 1, so that the nuts 5 are threadedly connected thereto to achieve a locking effect, thereby limiting the rotation of the baffle 2. This loading method greatly improves the manual clamping efficiency and the yield rate in the product production process, while also avoiding scratches and wear caused by traditional hook fixation.
[0024] like Figure 1 As shown, two vertical plates 3 are slidably provided on the frame 1, and a sliding groove 10 is provided on the side of the vertical plate 3 facing the groove 7. Through holes 8 are provided on both the upper and lower sides of the frame 1, and the through holes 8 are slidably connected to the vertical plates 3, as shown in FIG. Figure 4 As shown, bolt holes are provided on the upper and lower sides of the vertical plate 3, and bolts passing through the through holes 8 are provided in the bolt holes. The vertical plate 3 not only fixes the product to suspend it, but also adds an adjustable application range function on the basis of the integral traditional hanger. The realization of this function depends on the cooperation between the vertical plate 3 and the through hole 8. This clamping method is suitable for products of various sizes, breaks the limitation mode of traditional hangers, and reduces production costs to a certain extent.
[0025] like Figure 2As shown, two protrusions 6 are provided at corresponding levels in the two grooves 7, as shown in FIG. Figure 4 As shown, there are three slide grooves 10 on the side of the vertical plate 3, and the intervals between the slide grooves 10 correspond to the positions of the protrusions 6. Through the protrusions 6, multiple products can be placed in the hanger slot together and processed at one time, thereby improving production efficiency, shortening the production cycle and reducing production costs. At the same time, it avoids contact between products and reduces the risk of surface damage and scratches, which helps to maintain the integrity and quality of the product surface.
[0026] When in use, remove the bolts on the vertical plate 3 so that the vertical plate can move along the through hole 8. After moving the vertical plate 3 to the appropriate position, use the bolts to fix and lock the vertical plate 3, then remove the nuts 5 on the threaded rods 4 on both sides of the frame 1 and rotate the baffle 2 so that the baffle 2 rotates from a vertical state to a horizontal state, and insert the product from the groove 7 into the slide groove 10 on the side of the vertical plate 3. After the placement work is completed, change the baffle 2 from a horizontal state to a vertical state, and use the nuts 5 to cooperate with the threads of the threaded rod 4 to fix and lock the baffle 2. Finally, carry out development or etching work to ensure that the product is firmly suspended during the development or etching process, reducing the occurrence of misoperation and accidents.
[0027] The technical scope of the present invention is not limited to the contents described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the scope of protection of the present invention.
