Description

Technical Field

[0001] The utility model relates to the technical field of circuit board manufacturing, in particular to a gantry electroplating fixture for a circuit board. Background Art

[0002] In the production and manufacturing of circuit boards, multiple steps are required, including electroplating, welding, testing, etc. Electroplating is a very important step, and in the electroplating production process, stable clamping of the circuit board is the key to ensuring processing accuracy and product quality. Traditional clamps are generally similar to the structure of pliers, including a handle, a connector, and two pressure rods. By pressing down the handle, the two pressure rods move toward each other to clamp the circuit board. During the frequent opening and closing of the electroplating clamp, the end of the handle and the contact surface of the connector will produce metal shavings due to friction. The metal shavings are easy to fall on the surface of the circuit board, which not only contaminates the circuit board, but also may affect the uniform distribution of the plating solution and the quality of electroplating. Utility Model Content

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes a circuit board gantry electroplating fixture, which effectively reduces metal chips generated by friction and prevents them from falling on the circuit board by arranging a roller at the end of the handle to roll with the surface of the connecting piece, thereby improving the electroplating quality and production efficiency.

[0004] According to the first aspect of the utility model, the circuit board gantry electroplating fixture comprises a fixing component, a clamping component and a connecting piece. The fixing component is used to be connected to the gantry. The clamping component comprises two clamping rods, and the two clamping rods are respectively provided with insulating clamps in relative positions, and the two clamping rods move toward each other, and the insulating clamps abut against the board surface of the circuit board to clamp the circuit board. The connecting piece connects the fixing component and the clamping component, and the fixing component is located above the clamping component. The connecting piece is provided with a handle, and the handle rotates to drive the clamping rod to move and clamp. The end of the handle is rotatably connected to the connecting piece through a rotating shaft, and a clearance gap is provided at the end of the handle. The rotating shaft is arranged adjacent to the clearance gap, and the clearance gap accommodates a roller, and the roller is rotatably connected to the handle and abuts against the surface of the connecting piece so that the handle and the connecting piece are in rolling contact.

[0005] The gantry electroplating fixture for a circuit board according to an embodiment of the present invention has at least the following beneficial effects: The fixing component is used to be connected to the gantry of the electroplating equipment through fasteners such as bolts to ensure the stability of the fixture during the electroplating process. The clamping component is composed of two relatively arranged clamping rods. One end of each clamping rod is fixedly connected to the connecting piece, and the other end is equipped with an insulating chuck. The insulating chuck is made of non-conductive material to ensure that the circuit board will not be damaged during the clamping process. The clamping rods move relative to each other through an internal mechanical structure. When the two clamping rods approach each other, the insulating chucks can abut against and clamp the circuit board. It should be noted that the connecting piece is located between the fixing component and the clamping component and plays a role in transmitting power and supporting. A rotating shaft is provided thereon for connecting the handle. A relief notch is designed at the end of the handle, and a roller is embedded in the notch. The roller is made of wear-resistant material, such as cemented carbide or specially treated steel material, to reduce wear and the generation of metal chips. The roller is rotatably connected to the handle and abuts against the surface of the connecting piece to achieve rolling contact. Optionally, an appropriate amount of lubricant can be applied between the contact surfaces of the roller and the connecting piece to further reduce friction.

[0006] It can be understood that the roller at the end of the handle is in rolling contact with the surface of the connecting piece, greatly reducing the frictional force and the degree of wear, significantly reducing the generation of metal chips. The interference of metal chips to the electroplating process is reduced, ensuring the uniform distribution of the electroplating solution and the consistency of the electroplating thickness, and improving the electroplating quality. The wear caused by friction is reduced, the service life of the electroplating fixture is prolonged, and the maintenance cost is reduced.

[0008] According to some embodiments of the present invention, the width of the roller is equal to the width of the connecting piece.

[0009] According to some embodiments of the present invention, bearings are provided inside the connecting piece. The bearings are respectively connected to the handle and the clamping component, and a spring is provided at one end of the bearing connected to the handle.

[0010] According to some embodiments of the present invention, the insulating chuck is arc-shaped, and when the clamping component is in the clamping state, the two insulating chucks are located on the same horizontal plane, and anti-slip convex lines are provided on the surface of the insulating chuck.

[0023] In the production and manufacturing of circuit boards, multiple steps of processing are required, including electroplating, soldering, inspection, etc. Electroplating is a very important step. During the electroplating production process, the stable clamping of the circuit board is the key to ensuring processing accuracy and product quality. Traditional fixtures generally have a structure similar to pliers, including a handle, a connecting piece, and two pressing rods. By pressing down the handle, the two pressing rods move towards each other to clamp the circuit board. However, during the frequent opening and closing process of the electroplating fixture, metal chips are generated due to friction at the contact surface between the end of the handle and the connecting piece. The metal chips are likely to fall on the surface of the circuit board, not only polluting the circuit board but also possibly affecting the uniform distribution of the electroplating solution and the electroplating quality.

[0024] For this reason, referring to Figure 1 and Figure 2, the present utility model proposes a gantry electroplating fixture for a circuit board, which includes a fixing component 100, a clamping component 200, and a connecting component 300. The fixing component 100 is used to connect to the gantry. The clamping component 200 includes two clamping rods 210. Insulating chucks 220 are respectively arranged on the two clamping rods 210 in opposite positions. The two clamping rods 210 move towards each other, and the insulating chucks 220 abut against the board surface of the circuit board to clamp the circuit board. The connecting component 300 connects the fixing component 100 and the clamping component 200, and the fixing component 100 is located above the clamping component 200. A handle 400 is arranged on the connecting component 300. The handle 400 rotates to drive the clamping rods 210 to move and clamp. The end of the handle 400 is rotatably connected to the connecting component 300 through a rotating shaft 430. A relief notch 410 is arranged at the end of the handle 400. The rotating shaft 430 is arranged adjacent to the relief notch 410. A roller 420 is accommodated in the relief notch 410. The roller 420 is rotatably connected to the handle 400 and abuts against the surface of the connecting component 300, so that the handle 400 is in rolling contact with the connecting component 300.

[0025] Specifically, the fixing component 100 is used to connect to the gantry of the electroplating equipment through fasteners such as bolts to ensure the stability of the fixture during the electroplating process. The clamping component 200 is composed of two relatively arranged clamping rods 210. One end of each clamping rod 210 is fixedly connected to the connecting component 300, and the other end is equipped with an insulating chuck 220. The insulating chuck 220 is made of non-conductive material to ensure that the circuit board will not be damaged during the clamping process. The clamping rods 210 achieve relative movement through an internal mechanical structure. When the two clamping rods 210 approach each other, the insulating chucks 220 can abut against and clamp the circuit board. It should be noted that the connecting component 300 is located between the fixing component 100 and the clamping component 200, playing a role in transmitting power and supporting. A rotating shaft 430 is arranged thereon for connecting the handle 400. A relief notch 410 is designed at the end of the handle 400, and a roller 420 is embedded in the notch. The roller 420 is made of wear-resistant material, such as cemented carbide or specially treated steel material, to reduce wear and the generation of metal chips. The roller 420 is rotatably connected to the handle 400 and abuts against the surface of the connecting component 300 to achieve rolling contact. Optionally, an appropriate amount of lubricant can be applied between the contact surface of the roller 420 and the connecting component 300 to further reduce friction.

[0026] In a specific embodiment, the user first installs the fixing component 100 on the gantry and adjusts it to a suitable position, and then places the circuit board to be electroplated between the two insulating chucks 220. Then, hold the handle 400 and rotate the handle 400 to drive the roller 420 to roll on the surface of the connecting component 300, thereby driving the clamping rods 210 to move towards the circuit board until the insulating chucks 220 tightly clamp the circuit board.

[0027] It can be understood that the roller 420 at the end of the handle 400 is in rolling contact with the surface of the connecting member 300, greatly reducing the frictional force and the degree of wear, significantly reducing the generation of metal chips. The interference of metal chips in the electroplating process is reduced, ensuring the uniform distribution of the electroplating solution and the consistency of the electroplating thickness, and improving the electroplating quality. The wear caused by friction is reduced, the service life of the electroplating fixture is extended, and the maintenance cost is reduced.

[0028] Referring to Figure 2 , preferably, in some embodiments, the spacing of the relief notches 410 is designed to be greater than the width of the connecting member 300, so as to ensure that the roller 420 will not interfere with the edge of the connecting member 300 during rotation, thus ensuring the smoothness and stability of the rolling. At the same time, the larger spacing also provides a certain amount of movement space for the roller 420, which helps to further reduce friction and wear.

[0029] Further preferably, the width of the roller 420 is set to be equal to the width of the connecting member 300. The roller 420 can completely cover the contact surface of the connecting member 300, achieving the maximization of rolling contact, and further reducing the friction coefficient and wear rate. At the same time, the equal-width roller 420 and the connecting member 300 also ensure the uniform force on the contact surface, improving the stability and reliability of the clamping.

[0030] In a specific embodiment, bearings are added inside the connecting member 300. The bearings are respectively connected to the handle 400 and the clamping assembly 200, effectively reducing the frictional resistance when the handle 400 rotates. In addition, a spring 310 is provided at one end of the bearing connected to the handle 400. The elastic force of the spring 310 can exert a certain resetting effect on the handle 400, so that the handle 400 can automatically return to the initial position after being released, facilitating the next operation, not only improving the operation convenience, but also extending the service life of the fixture.

[0031] Referring to Figure 1 , specifically, the insulating chuck 220 is arc-shaped, and when the clamping assembly 200 is in the clamping state, the two insulating chucks 220 are located on the same horizontal plane. Such a design enables the insulating chuck 220 to better fit the surface of the circuit board, improving the uniformity and stability of the clamping. Further, anti-slip protrusions 221 are provided on the surface of the insulating chuck 220, increasing the frictional force with the circuit board and preventing the circuit board from sliding or falling off during the electroplating process.

[0032] Referring to Figure 1 , the fixing assembly 100 is composed of a first fixing rod 110 and a second fixing rod 120. The second fixing rod 120 is rotatably connected to the first fixing rod 110 through a fixing screw 130. When it is necessary to fix the fixture, only the second fixing rod 120 needs to be rotated towards the first fixing rod 110, and the fixing screw 130 is used to pass through the two rods at the same time for fastening.

[0033] Referring to Figure 1 , specifically, one clamping rod 210 is integrally formed with the first fixing rod 110 and both are perpendicular to the horizontal plane. The connecting member 300 is located in the middle of the first fixing rod 110 and this clamping rod 210, and the other clamping rod 210 is driven to move through the handle 400. This structure makes the overall structure of the fixture more compact and stable, and at the same time simplifies the design of the transmission mechanism. Further, in order to further improve the clamping stability and accuracy, the clamping assembly 200 is further provided with a guide plate 230. The guide plates 230 are respectively arranged on both sides of the clamping rod 210 integrally formed with the first fixing rod 110 for guiding the moving direction of the other clamping rod 210. The design of the guide plate 230 ensures that the clamping rod 210 always moves in a straight line during the movement, avoiding problems such as unstable clamping or damage to the circuit board caused by deviation or shaking.

[0034] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the gist of the present invention within the scope of knowledge possessed by those of ordinary skill in the art.
