Description

Technical Field

[0001] The present application relates to the technical field of FPC production, and more particularly to an FPC electroplating device. Background Art

[0002] In the manufacturing process of FPC (flexible printed circuit board), electroplating is a process of plating metal onto the circuit board. Currently, when electroplating a flexible printed circuit board, the circuit board is usually installed on a fixture, and the fixture is then hung in an electroplating tank, so that the circuit board is immersed in the electroplating solution. The anode in the electroplating tank is connected to the positive pole of the power supply, and the fixture is connected to the negative pole of the power supply, so that the metal is plated on the circuit board.

[0003] In the electroplating process control link, when it is necessary to conduct process verification tests for different circuit boards or meet the requirements of different plating thicknesses, the electroplating time required for different circuit boards will vary. This requires operators to record the electroplating time of each circuit board and promptly remove the fixture corresponding to the circuit board after reaching the set electroplating time. This process not only requires continuous on-site monitoring but also highly depends on the timely operation of the operator, and is easily affected by human factors, resulting in insufficient accuracy in controlling the electroplating time. Summary of the Invention

[0004] In order to improve the accuracy of electroplating time control, the present application provides an FPC electroplating device.

[0005] The present application provides an FPC electroplating device, adopting the following technical solutions: An FPC electroplating device includes: An electroplating tank filled with electroplating solution, and successively provided with a loading area, an electroplating area, and an unloading area along its width direction; An anode installed in the electroplating tank and connected to the positive pole of the power supply; A support rod that can move on the electroplating tank through a driving component provided on the electroplating tank, and can move between the loading area and the unloading area, and the support rod is connected to the negative pole of the power supply; An unloading rod provided in the unloading area and parallel to the support rod; and A fixture, which successively includes a hanging member and a mounting member from top to bottom. The hanging member is used to hang the support rod and the unloading rod, the mounting member is used to mount the workpiece to be plated, and a plurality of the fixtures are distributed along the length direction of the support rod; Wherein, the fixture has a first state and a second state relative to the support rod. When the fixture is in the first state, it is misaligned with the unloading rod, and when the fixture is in the second state, it is opposite to the unloading rod. When the workpiece to be plated on the fixture reaches the electroplating time, the fixture can be switched from the first state to the second state. At this time, the movement of the support rod can move the fixture from the support rod to the unloading rod.

[0006] By adopting the above technical solution, when the workpiece to be plated on the fixture reaches the electroplating time, the support rod can move to automatically move the fixture from the support rod to the blanking rod, eliminating the need for operators to continuously stay on-site and manually record the electroplating time, thereby improving the accuracy of electroplating time control and reducing the influence of human factors on electroplating quality.

[0007] Optionally, the support rod is provided with a pushing member corresponding to each fixture one by one, and the pushing member moves up and down relative to the support rod to push the corresponding fixture to switch its vertical position relative to the support rod, enabling the fixture to switch between the first state and the second state, and the pushing member is controlled by the electroplating time of the workpiece to be plated on the corresponding fixture.

[0008] By adopting the above technical solution, the pushing member can move up and down to push the fixture to switch its state, and the pushing member is controlled by the electroplating time of the workpiece to be plated on the corresponding fixture, enabling the state switching of the fixture to be automatically carried out precisely according to the electroplating time.

[0009] Optionally, one side of the upper and lower sides of the support rod has a protrusion, and the fixture is provided with a recess for the protrusion to fit into. When the fixture is in the first state, the protrusion and the recess are in mutual contact; when the fixture is in the second state, the protrusion and the recess are separated.

[0010] By adopting the above technical solution, when the fixture is in the first state, the protrusion and the recess are in mutual contact, ensuring the stability of the fixture during electroplating; when the fixture is in the second state, the protrusion and the recess are separated, facilitating the movement of the fixture from the support rod to the blanking rod.

[0011] Optionally, the hanging member includes a first hanging seat and a second hanging seat connected together, and the first hanging seat and the second hanging seat are distributed along the direction from the loading area to the blanking area; The first hanging seat has a first hanging cavity, the second hanging seat has a second hanging cavity, and one side of the first hanging seat facing away from the second hanging seat has a first entrance for the support rod to enter the first hanging cavity, and one side of the second hanging seat facing away from the first hanging seat has a second entrance for the blanking rod to enter the second hanging cavity; and the second hanging seat is also provided with a locking assembly for closing the second entrance after the blanking rod enters the second moving cavity.

[0012] By adopting the above technical solution, after the blanking rod enters the second hanging cavity, the second entrance is closed by the locking assembly, so that when the support rod moves away from the first hanging seat in a direction away from the blanking rod, the second hanging seat does not leave together with the support rod, thereby enabling the fixture to be switched in position and hung on the blanking rod.

[0013] Optionally, the locking component includes a closing rod that moves circumferentially in the second hanging seat and whose movement trajectory passes through the second entrance; an elastic member connected between the closing rod and the second hanging seat for giving the closing rod a tendency to move in the direction of closing the second entrance; a plug post that moves on the second hanging seat, and the closing rod has a jack for the plug post to be inserted into; when the plug post is inserted into the closing rod, the closing rod leaves the second entrance; and a linkage member disposed on the second hanging seat and located in the second hanging cavity and linked with the plug post; when the hanger moves to the position where the blanking rod enters the second hanging cavity, the blanking rod squeezes the linkage member to cause the linkage member to link the plug post to slide away from the closing rod, so that the closing rod closes the second entrance under the drive of the elastic member.

[0014] By adopting the above technical solution, when the hanger moves to the position where the blanking rod enters the second hanging cavity, the blanking rod squeezes the linkage member, causing the linkage member to link the plug post to slide away from the closing rod, and the closing rod closes the second entrance under the drive of the elastic member. The automatic locking setting eliminates the need for manual operation, improving the automation level and safety of the blanking process.

[0015] Optionally, the linkage member includes a connecting column connected to the second hanging seat; a sliding sleeve that is slidably sleeved on the connecting column along the direction parallel to the movement direction of the plug post; and a gear rotatably connected to the second hanging seat and located between the sliding sleeve and the plug post, and both the side of the sliding sleeve opposite to the plug post and the plug post have rack structures meshing with the gear; wherein, the blanking rod drives the plug post to slide away from the closing rod by squeezing the sliding sleeve in the direction close to the connecting column.

[0016] Optionally, the linkage member further includes a reset member, and the reset member is connected between the connecting column and the sliding sleeve for giving the sliding sleeve an elastic force to move away from the connecting column.

[0017] By adopting the above technical solution, the reset member gives the sliding sleeve an elastic force to move away from the connecting column, and the sliding sleeve transmits it to the plug post through the gear, so that when the sliding sleeve is not squeezed by the blanking rod, the plug post can maintain the state of being inserted into the closing rod.

[0018] Optionally, the closing rod is connected with a grip that passes through the second hanging seat.

[0019] Optionally, isolation parts are evenly spaced along the length direction of the support rod, and the isolation parts are used to isolate the hanging parts of two adjacent hangers.

[0020] By adopting the above technical solution, the isolation parts separate adjacent hangers, so as to improve the stability of the hangers.

[0021] Optionally, the anode parts are arranged on opposite sides of the electroplating bath.

[0022] By adopting the above technical solution, the anode parts are arranged on opposite sides of the electroplating bath. This arrangement can make the electric field distribution in the electroplating solution more uniform, which is beneficial to the uniform deposition of metal ions on the surface of the circuit board and improves the consistency and uniformity of the electroplating quality.

[0023] In summary, the present application includes at least one of the following beneficial effects: 1. By arranging driving parts corresponding to the hangers one by one on the support rod and automatically controlling them by the electroplating time, the automation of the state switching and blanking operation of the hangers is realized. When the workpiece to be plated reaches the preset electroplating time, through the movement of the driving parts and the support rod, the hanger is transferred from the support rod to the blanking rod to stop the electroplating of the workpiece on the hanger, so as to improve the accuracy and precision of the electroplating time control; 2. By triggering the locking assembly by the blanking rod to close the second inlet of the second hanging seat, the risk of the hanger detaching from the blanking rod can be reduced.

Detailed Description of the Embodiment

[0026] The following further describes the present application in conjunction with the attached Figure 1-8 drawings.

[0027] Embodiment 1: The embodiment of the present application discloses an FPC electroplating device. Refer to Figure 1 and Figure 2 , the FPC electroplating device includes an electroplating bath 1, an anode member 5, a support rod 6, an unloading rod 8, and a fixture 9. The electroplating bath 1 stores electroplating solution, the anode member 5 is placed in the electroplating bath 1 and immersed in the electroplating solution, and the anode member 5 is connected to the positive electrode of the power supply. The support rod 6 is installed on the electroplating bath 1 and connected to the negative electrode of the power supply, and the unloading rod 8 is installed on the electroplating bath 1 and insulated. The fixture 9 is used to install the flexible circuit board to be plated and can be hung on the support rod 6 and the unloading rod 8. When the fixture 9 is hung on the support rod 6, it conducts electricity through the support rod 6 to electroplate the circuit board. After the circuit board reaches the electroplating time, the support rod 6 moves to switch the corresponding fixture 9 of the circuit board to be hung on the unloading rod 8 to stop the electroplating of the circuit board.

[0028] Among them, the electroplating bath 1 has a square tank structure. The electroplating bath 1 is sequentially provided with a loading area 2, an electroplating area 3, and an unloading area 4 along its width direction. There are two groups of anode members 5, and the two groups of anode members 5 are respectively installed on the two sides of the electroplating bath 1 far away from each other along the width direction of the electroplating bath 1. Each group of anode members 5 has a plurality of anode rods evenly spaced along the length direction of the electroplating bath 1, and the anode rods are immersed in the electroplating solution. In order to promote the uniformity of the electroplating solution during electroplating, a circulation pump is installed in the electroplating bath 1 to circulate the electroplating solution, and an air pipe is also installed in the electroplating bath 1 to blow air into the electroplating solution to promote uniformity through bubbles. The circulation pump and the air pipe are both existing means to promote the uniformity of the electroplating solution, which will not be elaborated here and are not shown in the figure.

[0029] Refer to Figure 1 and Figure 3, the support rod 6 is in the shape of a square rod extending in parallel to the length direction of the electroplating pool 1, and the support rod 6 is relatively moved on the electroplating pool 1 by the drive of the driving assembly 7. Specifically, the driving assembly 7 includes a screw 71, a guide rod 72, a connecting seat 73 and a rotating motor 74. The screw 71 and the guide rod 72 are respectively installed on the outside of the opposite ends of the electroplating pool 1 along the length direction of the electroplating pool 1, the screw 71 is rotatably connected to the electroplating pool 1, and the length extension direction of the screw 71 and the guide rod 72 are parallel to the width direction of the electroplating pool 1. There are two connecting seats 73, one of which is threadedly sleeved on the screw 71, and the other connecting seat 73 is slidably sleeved on the guide rod 72, and the two connecting seats 73 are respectively connected to the two ends of the support rod 6 that are away from each other. The rotating motor 74 is installed on the electroplating pool 1 and the output end is connected to the screw 71 to drive the screw 71 to rotate. The rotating motor 74 can rotate forward and reversely to drive the support rod 6 to move horizontally between the loading area 2 and the unloading area 4 through the rotation of the screw rod 71. The unloading rod 8 is in the shape of a square rod parallel to the support rod 6 and is mounted on the unloading area 4 of the electroplating tank 1.

[0030] Referring to Figures 4 and Figure 5 , circuit boards requiring different plating times are mounted on different hangers 9, and different hangers 9 are spaced apart along the length direction of the electroplating tank 1 when hung on the support rod 6 or the feed rod 8. Each hanger 9 includes a hanging part 91 and a mounting part 92 connected in sequence from top to bottom.

[0031] Specifically, the hanging member 91 includes a first hanging seat 911 and a second hanging seat 912, which are distributed along the width direction of the electroplating pool 1 and fixedly connected. The first hanging seat 911 is in the shape of a long strip extending along the length direction of the electroplating pool 1. The first hanging seat 911 has a first hanging cavity 12 for hanging on the support rod 6. The first hanging seat 911 is provided with a first inlet 14 connected to the first hanging cavity 12 on the side away from the second hanging seat 912. The support rod 6 enters the first hanging cavity 12 from the first inlet 14. The second hanging seat 912 is in an arc-shaped structure and is provided with two along the length direction of the first hanging seat 911. The second mounting seat 912 has a second mounting cavity 13 for mounting on the blanking rod 8. A second inlet 15 communicating with the second mounting cavity 13 is provided on the side of the second mounting seat 912 away from the first mounting seat 911. The blanking rod 8 enters the second mounting cavity 13 from the second inlet 15. The mounting member 92 is in the shape of a hollow square frame, and the circuit board is clamped on the mounting member 92 by a clip. In this embodiment, the top of the mounting member 92 is fixed to the bottom of the second mounting seat 912.

[0032] The fixture 9 is hung on the support rod 6 by an operator fitting the first hanging seat 911 with the support rod 6. In order to distinguish fixtures 9 with different electroplating times, a plurality of pushing members 10 are evenly spaced along the length direction of the support rod 6, and the pushing members 10 correspond to the fixtures 9 one by one. Each group of pushing members 10 includes a telescopic power source 101 and a push rod 102. The telescopic power source 101 is installed in the support rod 6, and the telescopic end of the telescopic power source 101 is connected to the push rod 102 through a connecting rod. The push rod 102 slidably penetrates the support rod 6 vertically. When the first hanging seat 911 is hung on the support rod 6, the upper and lower ends of the push rod 102 are respectively opposite to the inner walls on the upper and lower sides of the first hanging seat 911.

[0033] Specifically, when the telescopic end of the telescopic power source 101 extends, the bottom end of the push rod 102 extends downward out of the support rod 6 and abuts against the inner bottom wall of the first hanging seat 911. At the same time, the inner top wall of the first hanging seat 911 abuts against the top wall of the support rod 6. At this time, the fixture 9 is in the first state relative to the support rod 6. When the telescopic end of the telescopic power source 101 retracts, the top end of the push rod 102 extends upward out of the support rod 6 and abuts against the inner top wall of the first hanging seat 911. At the same time, the inner bottom wall of the first hanging seat 911 abuts against the bottom wall of the support rod 6. At this time, the fixture 9 is in the second state relative to the support rod 6.

[0034] When hanging the fixture 9 on the support rod 6, the first hanging seat 911 is hung on the support rod 6 from the side of the support rod 6 close to the blanking rod 8, and the telescopic end of the telescopic power source 101 extends downward to make the fixture 9 in the first state. At this time, the highest point of the second hanging seat 912 on the fixture 9 is lower than the lowest point of the blanking rod 8. When electroplating the circuit board, the circuit board on the fixture 9 moves to the central position of the electroplating tank 1 under the combined drive of the support rod 6 and the drive assembly 7, that is, it is located in the electroplating area 3 of the electroplating tank 1, and the circuit board is electroplated at the electroplating area 3.

[0035] Refer to Figure 5 and Figure 6 When the circuit board reaches the required electroplating time, the telescopic end of the telescopic power source 101 retracts upward, and the push rod 102 pushes the corresponding fixture 9 upward to switch the fixture 9 to the second state. At this time, the second inlet 15 of the second hanging seat 912 on the fixture 9 is on the same horizontal plane as the blanking rod 8, that is, the second inlet 15 is opposite to the blanking rod 8. Subsequently, the support rod 6 moves to the blanking area 4, so that the fixture 9 on the support rod 6 in the first state is located below the blanking rod 8, and the second hanging seat 912 on the fixture 9 in the second state encloses the blanking rod 8 through the second hanging cavity 13, so that the fixture 9 corresponding to the electroplated circuit board is hung on the blanking rod 8. Among them, the telescopic power source 101 in this embodiment is a multi-stage electric telescopic rod, and the telescopic switching time of the telescopic power source 101 is set in the background system for controlling the telescopic power source 101.

[0036] In order to enable the support rod 6 to smoothly detach from the hanger 9 in the direction away from the discharge rod 8 after the second hanging seat 912 encloses the discharge rod 8, a locking assembly is provided on the second hanging seat 912. After the discharge rod 8 enters the discharge cavity through the second entrance 15, the discharge rod 8 can link the locking assembly to close the second entrance 15.

[0037] Reference Figure 5 , Figure 6 and Figure 7 Specifically, the locking assembly includes a closing rod 16, an elastic member 17, a plug post 18, and a linkage member 20. The closing rod 16 is in an arc shape coaxial with the second mounting seat 912. The closing rod 16 coaxially slides in the second mounting seat 912. The second entrance 15 is located in the moving path of the closing rod 16, and a plug hole 19 for plugging the plug post 18 is provided on the closing rod 16. The elastic member 17 is an arc spring installed in the second mounting seat 912. The two ends of the elastic member 17 that are far away from each other are respectively connected to the second mounting seat 912 and the closing rod 16. The elastic force of the elastic member 17 gives the closing rod 16 a tendency to close the second entrance 15 when the end of the elastic member 17 is away from the closing rod 16.

[0038] The plug post 18 slides horizontally on the second hanging seat 912 along the radial direction of the second hanging seat 912, one end of the plug post 18 extends into the second hanging seat 912, and the other end of the plug post 18 is located in the second hanging cavity 13. When the plug post 18 is inserted into the insertion hole 19, the plug post 18 positions the closing rod 16, and at this time, the end of the closing rod 16 away from the elastic member 17 is received in the second hanging seat 912, and the second inlet 15 is opened.

[0039] The linkage member 20 includes a connecting column 201, a sliding sleeve 202, a reset member 204, and a gear 203. The connecting column 201 is fixed to the inner wall of the second hanging seat 912 in the second hanging cavity 13, and the connecting column 201 is parallel to the inserting column 18. The sliding sleeve 202 is slidably sleeved on the connecting column 201 along the length direction parallel to the connecting column 201. The reset member 204 is a spring and is sleeved on the connecting column 201, and the two ends of the reset member 204 away from each other are respectively connected to the connecting column 201 and the sliding sleeve 202. The reset member 204 gives the sliding sleeve 202 an elastic force to move away from the connecting column 201. The gear 203 is rotatably connected to the second hanging seat 912 through a connecting seat 73 and is located in the second hanging cavity 13. The gear 203 is simultaneously located between the opposite surfaces of the sliding sleeve 202 and the inserting column 18, and rack structures are provided on the opposite surfaces of the sliding sleeve 202 and the inserting column 18. The sliding sleeve 202 and the inserting column 18 are meshed on the opposite sides of the gear 203 through the rack structures, so that when the sliding sleeve 202 moves relative to the connecting column 201, the inserting column 18 is driven to move in the opposite direction. It should be noted that a travel portion (not shown in the figure) protrudes from the outer wall of the connecting column 201, and a travel groove for the travel portion to slide along the length direction parallel to the connecting column 201 is provided on the inner wall of the sliding sleeve 202. The travel groove does not penetrate the end of the sliding sleeve 202 to guide the movement of the sliding sleeve 202, limit the sliding sleeve 202 from completely sliding off the connecting column 201, and at the same time limit the inserting column 18 from completely sliding off the second hanging seat 912.

[0040] During the process of the support rod 6 moving towards the blanking rod 8, the hanger 9 in the second state on the support rod 6 allows the blanking rod 8 to enter the second hanging cavity 13 through the second inlet 15. When the blanking rod 8 enters the second hanging cavity 13, the blanking rod 8 abuts against the end of the sliding sleeve 202 away from the connecting column 201. Subsequently, the support rod 6 continues to move towards the blanking rod 8, causing the blanking rod 8 to push the sliding rod towards the connecting column 201. At the same time, the sliding column drives the inserting column to move towards the blanking rod 8 through the cooperation of the gear 203 and the rack until it disengages from the closing rod 16, so that the closing rod 16 is driven by the elastic member 17 to move to close the second inlet 15. Subsequently, the support rod 6 moves away from the first hanging seat 911 in the direction away from the blanking rod 8. In the case where the second inlet 15 is closed, the hanger 9 will not disengage from the blanking rod 8 as the support rod 6 moves.

[0041] Referring to Figure 5 and Figure 7 Furthermore, a grip 21 is fixed on the closing rod 16. The grip 21 axially penetrates the second hanging seat 912 along the direction parallel to the axis of the second hanging seat 912. An arc-shaped hole 23 for the grip 21 to extend and slide is coaxially provided on the second hanging seat 912, so that it is convenient for the operator to push the closing rod 16 away from the second inlet 15 by pushing the grip 21, enabling the hanger 9 to be removed from the blanking rod 8.

[0042] Further, a contact rod 24 is fixed to the second hanging seat 912. The contact rod 24 is located in the second hanging cavity 13 and extends along the width direction of the electroplating bath 1 in parallel. When the blanking rod 8 enters the second hanging cavity 13, the top surface of the blanking rod 8 abuts against the bottom surface of the contact rod 24 to keep the fixture 9 stable.

[0043] Referring to Figure 3 , in addition, in order to improve the stability of the fixture 9 when hanging on the support rod 6, a protruding portion 11 protrudes upward from the top surface of the support rod 6, and a concave portion corresponding to the protruding portion 11 is provided on the inner top surface of the first hanging seat 911. When the first hanging seat 911 is hung on the support rod 6 and in the first state, the protruding portion 11 abuts into the corresponding concave portion to improve the stability between the support rod 6 and the first hanging seat 911. When the pushing member 10 pushes the second hanging seat 912 to move to the second state, the corresponding protruding portion 11 and the concave portion are separated from each other.

[0044] Referring to Figure 1 , furthermore, isolation portions 22 are fixedly sleeved on the support rod 6 and the blanking rod 8 at uniform intervals along their respective lengths, and the isolation portions 22 are annular. When the fixture 9 is hung on the support rod 6 or the blanking rod 8, there is an isolation portion 22 between adjacent fixtures 9 to limit the position of the fixture 9.

[0045] The implementation principle of an FPC electroplating device according to an embodiment of the present application is as follows: First, the flexible circuit board to be electroplated is installed on the fixture 9, and then the fixture 9 is successively hung on the support rod 6 located in the loading area 2 through the first hanging seat 911, and the telescopic ends of the respective telescopic power sources 101 on the support rod 6 are extended, and the recovery time of the telescopic ends of the respective telescopic power sources 101 is set according to the electroplating time of each circuit board.

[0046] The support rod 6 is moved to the electroplating area 3 and the power is turned on, so that the circuit board is electroplated in the electroplating area 3. When a circuit board reaches the electroplating time, the telescopic end of the corresponding telescopic power source 101 retracts to drive the push rod 102 to push the fixture 9 upward to move to the second state. Subsequently, the support rod 6 horizontally moves to the unloading area 4, so that the fixture 9 in the second state encloses the blanking rod 8 through the second hanging seat 912, and the closing rod 16 is unlocked to lock the second inlet 15, and then the support rod 6 returns to the electroplating area 3 again. Every time a circuit board reaches the set electroplating time, the support rod 6 performs a reciprocating operation from the electroplating area 3 to the unloading area 4 and then back to the electroplating area 3 until all the fixtures 9 are moved onto the blanking rod 8.

[0047] Embodiment 2: The difference between the embodiment of the present application and Embodiment 1 lies in that the connection manner between the second hanging seat 912 and the mounting member 92 is different.

[0048] Referring to Figure 8, specifically, in this embodiment, the top of the mounting member 92 is sleeved on the bottom of the second hanging seat 912, so that the mounting member 92 can swing circumferentially along the second hanging seat 912. The second hanging seat 912 is provided with limiting portions 25 opposite to the opposite sides of the mounting member 92 to limit the swinging range of the second hanging seat 912.

[0049] During electroplating, under the disturbance of the water flow caused by the circulation pump and the air flow caused by the air pipe, the mounting member 92 can shake relative to the second hanging seat 912 to be able to shake off the bubbles attached to the circuit board and relieve the edge effect, improving the uniformity of the plating layer.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
