Description

Technical Field

[0001] The present invention relates to the technical field of PCB equipment, and in particular to a spring-type conductive track structure and a PCB plate plating device. Background Art

[0002] Today's PCB equipment needs to conduct current while moving. The main method is to use conductive blocks or conductive plates to conduct electricity through friction on conductive rails to achieve power supply while moving. At present, the contact is usually between the planes of the sheets, and the conductive sheets are relatively long and have a large deformation. They are either tilted at both ends or tilted to one side, and cannot achieve surface-to-surface contact. Line contact is often formed, resulting in poor conductivity. In addition, due to long-term friction, after the conductive blocks are worn, the contact area changes, resulting in a change in overcurrent, making the transmitted overcurrent difficult to control, which can easily cause other problems such as thick or thin boards when the PCB equipment is plated.

[0003] In addition, the guide rail structure of current PCB equipment is easily affected by processing accuracy when conducting current, and has high requirements for installation. When the conductive block is in contact and conducting, it is easy to change from surface contact to line contact or point contact, which reduces the current passing through and causes a series of problems. Summary of the invention

[0004] The main purpose of the present invention is to propose a spring-type conductive track structure and a PCB plating device, which aims to ensure the contact area of ​​the conductive block during transmission on the conductive track, while reducing the occurrence of poor contact due to insufficient machining accuracy of the guide track structure, so as to maintain stable current transmission and improve the quality of the plated board.

[0005] To achieve the above object, the present invention provides a spring-type conductive track structure, comprising: a fixed conductive track, a movable conductive strip, and a plurality of conductive blocks and conductive springs, wherein:

[0007] Optionally, the conductive block is electrically connected to the fixed conductive rail via a corresponding conductive spring sheet, and when the movable conductive strip translates relative to the fixed conductive rail, the conductive block is compressed, and the compressed conductive block adheres closely to the movable conductive strip to conduct current under the elastic action of the corresponding conductive spring sheet.

[0008] Optionally, the conductive block is electrically connected to the movable conductive strip through a corresponding conductive spring sheet. When the movable conductive strip translates relative to the fixed conductive rail, the conductive block and the corresponding conductive spring sheet move along with the movable conductive strip.

At the same time, the small conductive blocks are connected with conductive springs. During work, the conductive springs will press the small conductive blocks to ensure that they are fully in contact and conduct, so as to achieve the purpose of conducting the components during movement. Compared with the rails in the prior art that will wear out, in this embodiment, the conductive rail structure is newly equipped with elastic conductive blocks and conductive springs for connecting electricity. The hanger will not be affected by the wear of the rails, the current fluctuation of the hanger will be reduced, and the wear of the rails will not affect the conductive performance.

[0027] Specifically, see Figure 1-3 As shown, Figure 1 A schematic structural diagram of a spring-type conductive track structure provided in an embodiment of the present invention; Figure 2 for Figure 1 Section view in the AA direction; Figure 3 Another structural schematic diagram of a spring-type conductive track structure provided by an embodiment of the present invention; Figure 4 for Figure 3 Section view along AA direction.

[0028] like Figure 1-Figure 3 As shown, the present invention provides a spring-type conductive track structure, comprising: a fixed conductive track 4, a movable conductive bar 1, and a plurality of conductive blocks 3 and conductive springs 2, wherein:

[0029] The plurality of conductive blocks 3 and the conductive spring sheets 2 are arranged between the fixed conductive rail 4 and the movable conductive bar 1 along the length direction of the fixed conductive rail 4. The conductive blocks 3 are electrically connected to the corresponding conductive spring sheets 2. The movable conductive bar 1 can translate relative to the fixed conductive rail 4. When the movable conductive bar 1 translates relative to the fixed conductive rail 4, under the elastic action of the corresponding conductive spring sheets 2, the conductive blocks 3 and the corresponding conductive spring sheets 2 are electrically connected to the fixed conductive rail 4 to conduct current.

[0030] Therefore, by setting a plurality of small conductive blocks 3, they can be in contact and conduct electricity at the same time. In actual operation, the contact area during transmission is guaranteed, and the occurrence of poor contact due to insufficient processing precision is reduced. At the same time, the small conductive blocks 3 are connected with conductive springs 2. During operation, the conductive springs 2 will press the small conductive blocks 3 to ensure that they are fully in contact and conduct, so as to achieve the purpose of conducting electricity during movement of the components. Compared with the rails in the prior art that will wear out, in this embodiment, the conductive rail structure adds elastic conductive blocks 3 and conductive springs 2 to connect electricity, the hanger will not be affected by the wear of the rails, the current fluctuation of the hanger will be reduced, and the wear of the rails will not affect the conductive performance.

[0031] Specifically, as an implementation mode, the conductive block 3 and the conductive spring sheet 2 can be installed on the fixed conductive rail 4, that is, the conductive block 3 is electrically connected to the fixed conductive rail 4 through the corresponding conductive spring sheet 2, and the movable conductive bar 1 compresses the conductive block 3 when it translates relative to the fixed conductive rail 4, and the compressed conductive block 3, under the elastic action of the corresponding conductive spring sheet 2, adheres closely to the movable conductive bar 1 to conduct current.

[0032] As an implementation method, the width of the movable conductive strip 1 may be greater than the width of the conductive block 3 so that when the movable conductive strip 1 translates relative to the fixed conductive rail 4 and compresses the conductive block 3 , it may better contact the conductive block 3 .

[0033] The movable conductive strip 1 can be a strip-shaped block. The conductive block can be a copper block.

[0034] Further, as an implementation method, the conductive spring piece 2 may be in a C-shape, a Z-shape, an S-shape or other shapes that are convenient for generating elastic effects.

[0035] The working principle of the spring-type conductive track structure of this embodiment is as follows:

[0036] The mobile conductive strip 1 is controlled to translate, and the mobile conductive strip 1 compresses the small conductive blocks 3 in sequence, and compresses multiple blocks at the same time. Under the action of the conductive spring 2, the small conductive blocks 3 fully contact the mobile conductive blocks 3; in this process, the current can be transmitted from the fixed conductive rail 4 to the conductive spring 2, and then transmitted to the mobile conductive strip 1 through the small conductive blocks 3, so as to be transmitted to other positions on it to realize its function. Therefore, the small conductive blocks 3 can be used to conduct electricity by friction on the mobile conductive strip 1 to realize power supply during movement.

[0037] Among them, the conductive spring piece 2 is elastic in a "C" shape, "S" shape or "Z" shape, etc. When the small conductive block 3 is compressed, the conductive spring piece 2 is deformed, so that the small conductive block 3 can be tightly pressed on the movable conductive bar 1 to fit the conducting current. If the position or angle of the movable conductive bar 1 is offset during installation, the small conductive block 3 will still fit the movable conductive bar 1 to a large extent under the action of the conductive spring piece 2, thereby ensuring the contact area between the two.

[0038] In the above process, the conductive spring sheet 2 can be pressed to ensure the tightness of the contact, and there is no rigid single-point fixation, which can fully adapt to the changes in the contact environment and ensure the transmission of current.

[0039] Compared with the prior art, in this embodiment, the installation method of the small conductive block 3 is different from the installation method of other conductive blocks 3. It is directly installed on the conductive spring sheet 2. This method makes the small conductive block 3 more flexible. After the conductive element in friction contact is worn, it can adapt to and fit the worn position, so that the current transmission remains stable.

[0040] In addition, there are multiple small conductive blocks 3 that are compressed and contacted. If one of the small conductive blocks 3 has poor contact due to special circumstances, the remaining conductive blocks 3 can still function as conductive blocks, thereby preventing electroplating problems of the unit due to obstruction of current transmission.

[0041] Moreover, the conductive spring piece 2 is conductive itself, and no conductive wire is used to transmit current to the small conductive block 3 . This simplifies the structure and prevents the conductive wire from affecting the conductive spring piece 2 in pressing the small conductive block 3 .

[0042] Further, as an extended embodiment, in other embodiments, the conductive spring piece 2 and the small conductive block 3 can also be installed on the movable conductive bar 1 to move with the movable conductive bar 1 .

[0043] Specifically, the conductive block 3 is electrically connected to the movable conductive bar 1 through the corresponding conductive spring sheet 2. When the movable conductive bar 1 translates relative to the fixed conductive rail 4, the conductive block 3 and the corresponding conductive spring sheet 2 move along with the movable conductive bar 1. The conductive block 3 is compressed under the elastic action of the corresponding conductive spring sheet 2 and adheres closely to the fixed conductive rail 4 to conduct current.

[0044] The shrapnel-type conductive track structure and the PCB plating device proposed in the embodiment of the present invention include: a fixed conductive track 4, a movable conductive strip 1, and a plurality of conductive blocks 3 and conductive shrapnel 2, wherein the plurality of conductive blocks 3 and the conductive shrapnel 2 are arranged between the fixed conductive track 4 and the movable conductive strip 1 along the length direction of the fixed conductive track 4, the conductive blocks 3 and the corresponding conductive shrapnel 2 are electrically connected, the movable conductive strip 1 can be translated relative to the fixed conductive track 4, and the movable conductive strip 1 is translated relative to the fixed conductive track 4. When the circuit track 4 translates, under the elastic action of the corresponding conductive spring sheet 2, the current is conducted through the conductive block 3 and the corresponding conductive spring sheet 2 electrically connected to the fixed conductive track 4. In this solution, by setting up multiple small conductive blocks 3, they can be in contact and conduct electricity at the same time. In actual work, it not only ensures the contact area during transmission, but also reduces the occurrence of poor contact due to insufficient processing accuracy. At the same time, the small conductive block 3 is connected with the conductive spring sheet 2. During work, the conductive spring sheet 2 will press the small conductive block 3 to ensure that it is fully in contact and conducts, so as to achieve the purpose of conducting electricity during movement of the component. Compared with the track wear in the prior art, in this embodiment, the conductive track structure is newly connected with elastic conductive blocks 3 and conductive spring sheets 2. The hanger will not affect the current due to the wear of the track, and the current fluctuation of the hanger will be reduced. In addition, the wear of the track will not affect the conductive performance.

All equivalent structural changes made by using the contents of the present invention specification and drawings under the concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
