Abstract
Description
Technical Field
[0001] This utility model relates to the field of PCB manufacturing technology, and in particular to a vertical frame carrier for PCB boards. Background Technology
[0002] In the electroplating process of PCB boards, a frame is used to hang the PCB boards and place the frame on electrode plates to conduct current. Then, a machine immerses the frame with the PCB boards in the electroplating solution, ensuring the solution is evenly distributed. To ensure the PCB boards do not move or fall during transportation and when entering and leaving the electroplating solution, the frame needs a positioning structure. Existing board carriers typically lack structures to guide liquid droplets from the frame, resulting in a large number of droplets adhering to the frame and potentially contaminating the workshop. Utility Model Content
[0003] The purpose of this utility model is to provide a vertical frame carrier for PCB boards, which aims to solve the technical problem that the existing technology lacks a structure that can guide the droplets on the frame, resulting in a large number of droplets adhering to the frame and easily causing pollution to the workshop.
[0004] To achieve the above objectives, this utility model provides a PCB vertical frame carrier, including an upward-opening frame. Several side rails are symmetrically arranged on the left and right sides of the frame. Several steel bars are vertically arranged on each side rail, with each steel bar arranged along its extension direction. A clamping groove is formed between two steel bars for clamping the board. A bottom beam is provided at the bottom of the frame, and several slots are provided at the top of the bottom beam for fixing the bottom of the board. Each slot corresponds to a clamping groove. Several flow guides are provided on the steel bars. The top of each flow guide has an inverted V-shape, the bottom of each flow guide has a V-shape, and the center of each flow guide has a diamond-shaped flow hole.
[0005] Preferably, the side rails are arranged vertically on the left and right sides of the frame, and the frame is also provided with mounting plates on both sides. The upper and lower ends of the mounting plates are respectively connected to one of the side rails, and a nameplate is provided on the outside of the mounting plates.
[0006] Preferably, the side guardrail extends into the frame with a guide plate, the first end of the guide plate being connected to the side guardrail and the last end being connected to each of the steel bars.
[0007] Preferably, the top of the clamping groove is provided with a V-shaped opening.
[0008] Preferably, each of the steel bars is provided with a plurality of connecting protrusions, and each of the connecting protrusions on the steel bar is respectively connected to one of the side guardrails.
[0009] Preferably, the middle part of the guide portion protrudes into the clamping groove and has a rounded corner, which abuts against one side of the plate.
[0010] The PCB board vertical frame carrier provided in this embodiment of the utility model has at least one of the following technical effects:
[0011] In use, the plate is inserted through the opening at the top of the frame. The sides of the plate move downwards along the clamping grooves until the bottom of the plate is fixed in the slot. Once the frame is full, the plate is processed by immersing the frame in the chemical solution tank. After the process is completed, the frame is lifted out of the chemical solution tank. The chemical solution adhering to the frame flows downwards through the guiding action of the steel strip. During this process, the chemical solution flows downwards from the main body of the steel strip to the guide section, and is guided away from the main body of the steel strip by the top of the guide section. It is then quickly flushed out and detached from the top of the guide section. The droplets at the bottom of the guide section are guided and collected to flow downwards to another guide section below the steel strip body. They are then guided away from the main body of the steel strip by the top of the lower guide section and flushed out and detached from the top of the guide section. At the same time, the diamond-shaped guide holes can increase the collection effect of the guide section on the droplets, which can better discharge the droplets, reduce the droplets adhering to the frame, and reduce environmental pollution in the workshop.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0021] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.
[0022] In one embodiment of this utility model, such as Figures 1-4As shown, a vertical frame carrier for PCB boards is provided, including an upward-opening frame 1. Several side rails 2 are symmetrically arranged on the left and right sides inside the frame 1. Several steel bars 21 are vertically arranged on the side rails 2. Each steel bar 21 is arranged along the extension direction of the side rail 2. A clamping groove 22 is formed between two steel bars 21 for clamping the board. A bottom beam 23 is provided at the bottom of the frame 1. Several slots 24 are provided at the top of the bottom beam 23 for fixing the bottom of the board. Each slot 24 corresponds to a clamping groove 22. Several flow guides 3 are provided on the steel bars 21. The top of the flow guide 3 has an inverted V-shaped structure. The bottom of the flow guide 3 has a V-shaped structure. The middle of the flow guide 3 has a diamond-shaped flow guide hole 31.
[0023] Furthermore, the side rails 2 are arranged vertically on the left and right sides of the frame 1. Mounting plates 11 are also provided on both sides of the frame 1. The upper and lower ends of each mounting plate 11 are connected to a side rail 2, and a nameplate 12 is provided on the outer side of each mounting plate 11. A guide plate 211 extends from the side rail 2 into the frame 1. The head of the guide plate 211 is connected to the side rail 2, and the end is connected to each of the steel bars 21. Specifically, the side guard plate has a plate-like structure. The mounting plate 11 is fixed between the two side guard plates located in the middle of the frame 1. The guide plate 211 is set on the side of the side guard plate away from the mounting plate 11 and extends downward at an angle. At the same time, each steel bar 21 can be set on the side of the guide plate 211 away from the mounting plate 11. When the frame 1 is lifted from the medicine tank, the water flows down from the side guard plate through the guide plate 211. As the water flow gradually decreases, the medicine left by the side guard plate through the guide plate 211 will be guided by the steel bars 21 and the guide part 3 to avoid too much medicine remaining on the plate after flowing out.
[0024] Furthermore, the clamping groove 22 has a V-shaped opening at the top. Specifically, since the top of the guide part 3 is an inverted V-shaped structure, the guide parts 3 on the front and rear steel bars 21 are combined to form a V-shaped structure, thereby forming a V-shaped opening at the top of the clamping groove 22, which provides a good guiding effect when inserting the plate and makes it easier for the plate to be inserted into the clamping groove 22.
[0025] Furthermore, each of the steel bars 21 is provided with a plurality of connecting protrusions 212, and each of the connecting protrusions 212 on the steel bar 21 is connected to a side guardrail 2. The middle part of the guide portion 3 protrudes into the clamping groove 22 to form a rounded corner 213, and the rounded corner 213 abuts against one side of the plate. Specifically, a steel bar 21 has at least four connecting protrusions 212, each of which is connected to a guide section 3. The connecting protrusion 212 at the top of the steel bar 21 is fixedly connected to the top of the guide section 3 at the top, and the connecting protrusion 212 at the bottom of the steel bar 21 is fixedly connected to the bottom of the guide section 3 at the bottom. The connecting protrusion 212 in the middle of the steel bar 21 is also connected to a support beam. The support beam is set in the guide hole 31 and is fixedly connected to the widest two sides of the guide hole 31, thus achieving a support effect in the guide hole 31. After the plate is placed in the clamping groove 22, the front and rear sides of the plate are limited by each rounded corner 213, which reduces the contact area between the plate and the inner wall of the clamping groove 22, resulting in better processing of the plate.
[0026] Working principle: In use, the plate is inserted through the opening at the top of the frame 1. The sides of the plate move downwards along the clamping grooves 22 until the bottom of the plate is fixed in the slot 24. When the frame 1 is full, the plate is processed by immersing the frame 1 in the chemical solution tank. After the process is completed, the frame 1 is lifted out of the chemical solution tank. The chemical solution adhering to the frame 1 flows downwards through the guiding action of the steel bar 21. During this process, the chemical solution flows downwards from the main body of the steel bar 21 to the guide section 3, and is guided away from the steel bar 21 by the top of the guide section 3. The main body flows in the direction of the main body and rushes out and detaches from the top of the guide section 3 at a relatively fast speed. The droplets located at the bottom of the guide section 3 are guided and gathered to flow to another guide section 3 below the main body of the steel bar 21. They are guided away from the main body of the steel bar 21 by the top of the guide section 3 below and rush out and detach from the top of the guide section 3. At the same time, by setting the diamond-shaped guide hole 31, the gathering effect of the guide section 3 on the droplets can be increased, which can better discharge the droplets, reduce the droplets attached to the frame 1, and reduce the environmental pollution in the workshop.
[0027] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
