Description

Technical Field

[0001] The invention relates to the technical field of electroplating hangers, in particular to an electroplating hanger which is convenient for clamping and is used for manufacturing flexible circuit boards. Background Art

[0002] Electroplating is the process of plating a thin layer of other metals or alloys on certain metal surfaces using the principle of electrolysis. It is a process that uses electrolysis to attach a layer of metal film to the surface of metal or other material parts, thereby preventing metal oxidation, improving wear resistance, conductivity, reflectivity, corrosion resistance and enhancing aesthetics. Flexible circuit boards, also known as "soft boards", are printed circuits made of flexible insulating substrates. Flexible circuits provide excellent electrical properties and can meet the design needs of smaller and higher density installations. They also help reduce assembly processes and enhance reliability. During the processing, they also need to be electroplated. During the electroplating process of flexible circuit boards, electroplating hangers are required to clamp them.

[0003] The conventional flexible circuit board electroplating rack has the advantages of simple structure and convenient operation, but still has its shortcomings.

[0004] When using traditional flexible circuit board electroplating hangers, the edges of the flexible circuit board are subjected to different forces, which can easily cause wrinkles on the surface of the flexible circuit board, thereby affecting the electroplating effect and causing uneven lamination, resulting in short circuits and scrapping, and failing to meet production requirements. Summary of the invention

[0005] The object of the present invention is to provide a plating rack that is easy to clamp for making flexible circuit boards, so as to solve the problem of different forces at the edges of the flexible circuit boards mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an electroplating hanger for manufacturing a flexible circuit board that is easy to clamp, comprising a top plate, a fixing structure and an anti-slip structure;

[0007] Four connecting plates are installed at the bottom end of the top plate, and a mounting plate is installed at the bottom end of the connecting plate. Slots are opened inside both sides of the mounting plate, and a flexible circuit board body is arranged on both sides of the mounting plate. The anti-slip structure is located at the upper and lower ends of the mounting plate.

[0008] The fixing structure is located at the upper and lower ends of the mounting plate;

[0009] The fixing structure includes an active rod, which is installed at the middle position of the top end of the mounting plate through a rotating shaft, and a knob is installed at the top end of the active rod, and driving wheels are installed on the outer walls of the active rod at the upper and lower ends of the mounting plate, and mounting grooves are installed on the front and rear ends of the upper and lower ends of one side of the mounting plate, threaded rods are installed on both sides of the inside of the mounting groove through rotating shafts, and threaded blocks are connected to the outer walls of the threaded rods through threads, driven gears are installed at the ends of the threaded rods close to each other, and splints are installed at the ends of the threaded blocks close to the flexible circuit board body, driven rods are installed at the ends of the mounting groove close to the flexible circuit board body through rotating shafts, and driven wheels are installed at the ends of the driven rods away from the flexible circuit board body, and transmission chains are connected between the driven wheels and the driving wheels.

[0010] Preferably, the bottom end of the active rod passes through the mounting plate, and the bottom end of the active rod extends to below the mounting plate, and one side of the mounting groove passes through the mounting plate and extends to the other side of the mounting plate.

[0011] Preferably, one end of the driven rod passes through the mounting groove, and one end of the driven rod extends to the outside of the mounting groove.

[0012] Preferably, one end of the clamping plate close to the flexible circuit board body passes through the mounting groove, and one end of the clamping plate close to the mounting groove extends to one side of the flexible circuit board body.

[0013] Preferably, the driving gear and the driven gear are close to each other, and the driving gear and the driven gear are meshed with each other.

[0014] Preferably, the anti-slip structure includes a push plate, a push rod, a cavity, a slider and a fixed spring, the cavities are opened at the upper and lower ends inside the mounting plate, and two sliders are arranged inside the cavity, a push rod is installed at one end of the slider close to the flexible circuit board body, and a fixed spring is sleeved on the outer wall of the push rod inside the cavity, and a push plate is installed at one end of the push rod close to the flexible circuit board body.

[0015] Preferably, one end of the push rod close to the flexible circuit board body passes through the mounting plate, and one end of the push rod close to the flexible circuit board body extends to the inside of the slot.

[0016] Preferably, the push rods all form a sliding structure through the slider and the cavity, and the fixed springs are all fixedly installed between the slider and the cavity.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: by turning the knob, the active rod is driven to rotate through the knob, and the active wheel is driven to rotate through the active rod. Since the active wheel and the driven rod are connected to each other through a transmission chain, the driven wheel can be driven to rotate during the rotation of the active wheel, and the driven rod can be driven to rotate through the driven wheel, and the active gear can be driven to rotate through the driven rod. Since the active gear and the driven gear are meshed with each other, the driven gear can be driven to rotate during the rotation of the active gear, and the rotation directions of the two driven gears located in the same mounting groove are opposite, and the threaded rod can be driven to rotate through the driven gear. Since the threaded rod and the threaded block are connected through a transmission chain, the threaded rod can be driven to rotate. The threaded connection is a process in which the threaded rod rotates, so that the threaded block can be driven to move along the thread on its outer wall, and the two threaded blocks located in the same mounting groove move in opposite directions. The threaded block drives the clamping plate to move, and by adjusting the rotation direction of the knob, the threaded blocks in the same mounting groove move toward each other, and the clamping plate is driven by the threaded block to approach the flexible circuit board body. The flexible circuit board body can be fixed by the clamping plate, and the clamping plates located on the same side move the same distance, so the force for fixing the flexible circuit board body is the same, thereby preventing the flexible circuit board surface from wrinkling due to different forces at the edges of the flexible circuit board.

[0028] The bottom end of the active rod 11 passes through the mounting plate 8, and the bottom end of the active rod 11 extends to the bottom of the mounting plate 8, and one side of the mounting groove 1 passes through the mounting plate 8 and extends to the other side of the mounting plate 8;

[0029] One end of the driven rod 4 passes through the mounting groove 1, and one end of the driven rod 4 extends to the outside of the mounting groove 1;

[0030] One end of the clamping plate 6 close to the flexible circuit board body 17 passes through the mounting groove 1, and one end of the clamping plate 6 close to the mounting groove 1 extends to one side of the flexible circuit board body 17;

[0031] The driving gear 10 and the driven gear 16 are close to each other, and the driving gear 10 and the driven gear 16 are meshed with each other;

[0032] Specifically, Figure 1 , Figure 2 and Figure 3 As shown, when the mechanism is used, the rotation direction of the knob 12 is adjusted to make the threaded blocks 2 in the same mounting slot 1 move toward each other, and the threaded blocks 2 drive the clamping plates 6 to approach the flexible circuit board body 17. The flexible circuit board body 17 can be fixed by the clamping plates 6, and the clamping plates 6 on the same side move the same distance, so the force for fixing the flexible circuit board body 17 is the same.

[0033] Embodiment 2: The anti-slip structure 9 includes a push plate 901, a push rod 902, a cavity 903, a slider 904 and a fixed spring 905. The cavities 903 are opened at the upper and lower ends of the mounting plate 8, and two sliders 904 are arranged inside the cavity 903. The sliders 904 are installed with push rods 902 at one end close to the flexible circuit board body 17, and the outer wall of the push rod 902 in the cavity 903 is sleeved with a fixed spring 905, and the push plate 901 is installed at one end of the push rod 902 close to the flexible circuit board body 17;

[0037] Working principle: The staff places the flexible circuit board body 17 to be fixed on both sides of the mounting plate 8, and then the staff turns the knob 12, and drives the active rod 11 to rotate through the knob 12, and drives the active wheel 18 to rotate through the active rod 11. Since the active wheel 18 and the driven rod 4 are connected to each other through the transmission chain 15, the driven wheel 3 can be driven to rotate during the rotation of the active wheel 18, and the driven rod 4 can be driven to rotate through the driven wheel 3, and the active gear 10 can be driven to rotate through the driven rod 4. Since the active gear 10 and the driven gear 16 are meshed with each other, the driven gear 16 can be driven to rotate during the rotation of the active gear 10, and the rotation directions of the two driven gears 16 located in the same mounting slot 1 are the same. In the opposite direction, the threaded rod 5 can be driven to rotate by the driven gear 16. Since the threaded rod 5 is connected to the threaded block 2 by threads, the threaded block 2 can be driven during the rotation of the threaded rod 5, so that the threaded block 2 moves along the threads on its outer wall, and the two threaded blocks 2 located in the same mounting groove 1 move in opposite directions. The clamping plate 6 is driven to move by the threaded block 2, and the threaded blocks 2 in the same mounting groove 1 are moved in a direction approaching each other by adjusting the rotation direction of the knob 12. The clamping plate 6 is driven by the threaded block 2 to approach the flexible circuit board body 17, and the flexible circuit board body 17 can be fixed by the clamping plate 6, and the clamping plates 6 located on the same side move the same distance, so the force for fixing the flexible circuit board body 17 is the same;

[0038] During the process of fixing the flexible circuit board body 17, the flexible circuit board body 17 will push the push plate 901, and push the push rod 902 through the push plate 901, so that the push rod 902 pushes the slider 904, so that the slider 904 slides in the direction of approaching each other inside the cavity 903, and drives the fixing spring 905 through the slider 904 to stretch the fixing spring 905. If the teeth slip inside the installation groove 1 and the fixation becomes loose, the slider 904 can be driven under the reaction force of the fixing spring 905 to move the slider 904 in the direction close to the flexible circuit board body 17, and push the push rod 902 through the slider 904, so that the push rod 902 pushes the push plate 901, and the push plate 901 is always in contact with the flexible circuit board body 17 through the push plate 901 to prevent the flexible circuit board body 17 from slipping off.

[0039] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
