[0046] The following are only preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention.

[0047] like Figures 1 to 24 As shown, the present invention provides a fully automatic gold plating method for a circuit board, which comprises the following steps:

[0048] A full-board reflux line 10 is provided at the output end of the feed unit 2 and the input end of the discharge unit 3.

[0049] An empty frame return line 11 is provided at the output end of the discharging unit 3 and the input end of the feeding unit 2.

[0050] The multiple circuit boards 01 are inserted into the board frame 02 one by one and continuously by using the board inserting and receiving machine 4 of the feeding unit 2.

[0051] s is sent to the discharging unit 3,

[0052] The multiple circuit boards 01 are taken out from the board frame 02 one by one and continuously by using the board unloading machine 5 of the unloading unit 3 , and the empty board frame 02 after unloading flows back to the feeding unit 2 via the empty frame return line 11 .

[0053] The present invention discloses a fully automatic gold plating equipment for circuit boards. The equipment comprises a gold plating unit 1, a feeding unit 2 and a discharging unit 3. A full board reflow line 10 is provided between the output end of the feeding unit 2 and the input end of the discharging unit 3. An empty frame reflow line 11 is provided between the output end of the discharging unit 3 and the input end of the feeding unit 2. The feeding unit 2 is provided with a frame inserting and receiving machine 4 for inserting a plurality of circuit boards 01 into a frame 02. The discharging unit 3 is provided with a frame discharging and placing machine 5. The full board reflow line 10 sends a full board frame 02 of the frame inserting and receiving machine 4 into the gold plating unit 1 for gold plating and outputs the full board frame 02 after gold plating into the discharging unit 3. The frame discharging and placing machine 5 is used to take out the circuit boards 01 after gold plating from the frame 02 one by one. The empty frame reflow line 11 inputs the empty frame reflow of the frame discharging and placing machine 5 into the frame inserting and receiving machine 4. The present invention adopts such a structural design to realize the process of automatic circuit board entering the frame, integrated feeding into the gold-plating process after entering the frame, circuit board unloading and empty frame reflow board insertion process, which has a high degree of automation and greatly improves the gold-plating efficiency of the circuit board and the product yield.

[0054] like Figure 2-7 As shown, the frame inserting and receiving machine 4 is provided with a frame inserting movement, a first board picking robot 41 and a first board frame picking robot 42. In actual work, the first board picking robot 41 will pick up the circuit boards 01 from the outside and send them into the frame inserting movement one by one. The frame inserting movement is used to insert multiple circuit boards 01 into the board frame one by one, and then the full board frame 02 after the first board frame picking robot 42 inserts the board is moved into the full board return line 10, and then the first board frame picking robot 42 is used to send the empty frame of the empty frame return line 11 into the frame inserting machine, so as to repeat the above steps to continue to insert the next batch of circuit boards 01.

[0055] Among them, in this embodiment, the insert frame core adopts the structure of inclined insert plate, and the insert frame core has a circuit board input unit 40 and a plate frame insert plate unit 43. The circuit board input unit 40 is equipped with a rotating material transfer platform 401, and the plate frame insert plate unit 43 is equipped with a rotating plate frame limit seat 432. After the first plate picking manipulator 41 sends the circuit boards 01 into the circuit board input unit 40 one by one, the rotating material transfer platform 401 is parallel to the central axis of the rotating plate frame limit seat 432, and the material transfer platform 401 automatically tilts and inserts the carried circuit board 01 into the plate frame 02 carried by the plate frame limit seat 432. The rotating material transfer platform 401 and the rotating plate frame limit seat 432 are used in conjunction to allow the circuit board to enter the frame in an inclined posture. Compared with the prior art that adopts a vertical frame entry method, such a structural design makes the frame insertion more convenient and more efficient, and there is no need to set a separate manipulator to clamp the circuit board into the frame, which simplifies the structure of the insert frame core and optimizes the space utilization of the insert frame core, and has high practicality. Of course, in other embodiments, the frame inserting mechanism may also adopt a vertical insertion method, that is, a vertical lifting robot is used to clamp the circuit board 01 and vertically insert it into the board frame 02.

[0056] More specifically, the circuit board input unit 40 also includes a material receiving platform 400 fixedly mounted on the frame and a first power source 402 for driving a material transfer platform 401 to rotate relative to the material receiving platform 400. The material receiving platform 400 and the material transfer platform 401 are both equipped with a conveying roller group. When the first plate picking robot 41 delivers external circuit boards 01 into the material receiving platform 400 one by one, the conveying roller group of the material receiving platform 400 automatically delivers the circuit board 01 into the material transfer platform 401, and the conveying roller group of the material transfer platform 401 automatically inserts the circuit board 01 into the board frame 02. This structural design, by adding a material receiving platform 10, ensures that when the previous circuit board 01 is inserted into the frame, it will not affect the first board frame picking robot 42 to continue to load the next circuit board 01, thereby ensuring the continuity of the circuit board 01 inserted into the frame, which helps to improve the productivity of the production line. In addition, the material receiving platform 10 and the driving material transfer platform 401 both use a conveyor roller group to automatically transfer the circuit board 01. Compared with the mechanical structure that uses a mechanical gripper to clamp the plate into the frame, its structure is simpler and more ingenious, and the cost is lower.

[0057] Specifically, a material stopper 4010 is mounted above the material transfer platform 401. The material stopper 4010 is used to keep the circuit board in the material transfer platform 401. A material limiting component 4011 and a stopping component 4012 are provided at the end of the material transfer platform 401. The material limiting component 4011 has a discharge gap that allows a single circuit board to be discharged one by one. The stopping component 4012 is used to stop the circuit board 01 from being discharged temporarily. In the initial state, the stopping component 4012 stops the circuit board. After the circuit board 01 and the frame 02 are tilted and aligned, the rotating conveying roller group conveys the circuit board 01 into the frame. The discharge gap can ensure that multiple circuit boards 01 are discharged one by one. In addition, the material stopper 4010 can keep the circuit board in the material transfer platform 401 to prevent the circuit board 01 from falling off and being discharged during the conveying process.

[0058] Among them, the first power source 402 includes a first screw-nut mechanism 4020, a first transverse base 4021 drivingly connected to the first screw-nut mechanism 4020, a first transmission base 4022 fixedly installed on the material transfer platform 401, and a first transmission swing arm 4023 hinged between the first transverse base 4021 and the first transmission base 4022.

[0059] The first plate picking robot 41 includes a first negative pressure picking component, a lifting power component for driving the negative pressure picking component to pick up or put down components, and a lateral moving power component for driving the negative pressure picking component to slide and feed materials laterally.

[0060] Specifically, the plate frame plug-in unit 43 is also provided with a fixed head seat 430, a rotating head seat 431, a second power source 434 and a translation adjustment mechanism 433. The plate frame limit seat 432 is movably mounted on the rotating head seat 431 and is used to load the plate frame 02. The rotating head seat 431 is rotatably mounted on the fixed head seat 430. The second power source 434 drives the plate frame limit seat 432 to intermittently flip via the rotating head seat 431. The translation adjustment mechanism 433 is used to drive the plate frame limit seat 432 to slide intermittently, so that the multiple slots of the plate frame 02 carried in the plate frame limit seat 432 are switched one by one and aligned with the material transfer platform 401. Its structural design cleverly realizes the rapid and continuous insertion of multiple circuit boards 01 into the frame, optimizing the yield of the production line.

[0061] More specifically, the plate frame plug-in unit 43 also includes a push mechanism 435, which includes a push base 4350, a push cylinder 4351 and a push plate 4352. The push base 4350 is fixedly installed on the frame, and the push cylinder 4351 is fixedly installed on the push base 4350. The push base 4350 is rotatably installed with a first transmission link 4353, and the first transmission link 4353 is hinged with a first transmission shaft 4354, and the first transmission shaft 4354 is hinged with a second transmission link 4355. The push plate 4352 is rotatably installed with a second transmission shaft 4356, and the second transmission link 4355 is hinged to the second transmission shaft 4356. The push cylinder 4351 is transmission-connected to the first transmission shaft 4354 via a fisheye joint 272. The structure of flipping the electric push plate 4352 driven by multiple connecting rods further plays an auxiliary supporting role for the plate frame limit seat 432, ensuring the smooth rotation of the plate frame 02, wherein the push mechanism 435 and the second power source 434 are respectively arranged on the front and rear sides of the plate frame limit seat 432, and have good stability performance.

[0062] Among them, the second power source 434 includes a second screw-nut mechanism 4340, a second transverse base 4341 drivingly connected to the second screw-nut mechanism 4340, a second transmission base 4342 fixedly installed on the rotating head base 21, and a second transmission swing arm 4343 hinged between the second transverse base 4341 and the second transmission base 4342.

[0063] The plate frame limiting seat 432 has an open plate frame insertion groove, and the plate frame limiting seat 432 is installed with a plurality of first limiting members 436 and a plurality of second limiting members 437, and the first limiting members 436 and the second limiting members 437 are used in conjunction with each other to fix the relative position of the plate frame 02. Specifically, the plate frame insertion groove is a U-shaped structure, and with such a structural design, the plate frame 02 can be pushed into the plate frame insertion groove horizontally or lifted and placed vertically into the plate frame insertion groove, which has higher versatility and lower requirements for the plate frame picking gripper, and the first limiting member 436 and the second limiting member 437 are used in conjunction with each other to limit and fix the plate frame. Specifically, each of the first limiting members 436 includes a first limiting cylinder 4360 fixedly installed on the plate frame limiting seat 432 and a first limiting block 4361 driven and installed on the first limiting cylinder 4360. The first limiting block 4361 has a first limiting groove for clamping the plate frame. Each first limiting cylinder 4360 is used to drive the first limiting block 4361 to extend into the plate frame insertion groove. The first limiting block 4361 clamps the plate frame 02 through the first limiting groove to limit the position of the plate frame 02 in the X-axis direction. Specifically, each of the second limiting members 437 includes a second limiting cylinder 4370 fixedly mounted on the plate frame limiting seat 432 and a second limiting plate hinged on the plate frame limiting seat 432; the second limiting plate is fixedly provided with a second limiting block 4371 and a reversing seat 4373; the second limiting cylinder 4370 is driven and connected to a fisheye joint 4372; the reversing seat 4373 is rotatably connected to the fisheye joint 4372; the second limiting block 4371 is provided with a second limiting groove for clamping the plate frame; the second limiting cylinder 4370 drives the reversing seat 4373 to rotate via the fisheye joint 4372 so that the second limiting block 4371 extends into the plate frame insertion groove; the second limiting block 4371 clamps the plate frame 02 through the second limiting groove to limit the position of the plate frame 02 in the Y-axis direction.

The present invention uses a plate frame 02 to carry or clamp a plurality of circuit boards 01 at one time. The second picking unit 620 is used to pick up and fix the plate frame 02. The plate frame pick-and-place mechanism 623 drives the second picking unit 620 to move from the plate frame input mechanism 13 to the top of the temporary storage box 10. The plate frame 02 is temporarily stored in the temporary storage box 10 using the plate frame lifting mechanism 621. The circuit boards 02 are immersed in a water bath to prevent oxidation through the soaking liquid in the temporary storage box 10.

Among them, the distance adjustment component 6222 generally adopts a distance adjustment cylinder, and the number of the distance adjustment cylinders is at least two.

In the standby state and normal operation state, the power source 76 drives the conveying device 75 to slide back and forth between the material receiving station 72 and the reserved station 73. The sliding conveying device 75 receives the plate frame 02 delivered by the full plate return line 10 at the material receiving station 72, and outputs the plate frame 02 to the gold-plating unit 1 across the reserved station 73.

The flipping mechanism 512 is used to drive the material receiving robot 510 to flip so that the circuit board 01 is horizontally placed at the board feeding mechanism 52. The board feeding mechanism 52 is used to automatically output and unload the circuit board 01.

Specifically, the board taking lifting drive source 542 uses a drag chain transmission mechanism, and such a structural design has good transmission stability performance.

Block 5530; in actual applications, after the fully loaded material frame ready for unloading is moved into place along the material frame incoming track under the action of an external driving member, the plate frame positioning mechanism 55 limits the position of the delivered material frame to facilitate the vertical frame-outlet robot 4 to take the plate, wherein the plate frame positioning mechanism 55 drives the stop plate 5510 through the stop cylinder 551 to extend into the incoming track to stop the material frame, the X-axis positioning cylinder 552 limits the X-axis position of the material frame through the X-axis positioning block 5520, and the Y-axis positioning cylinder 553 limits the Y-axis position of the material frame through the Y-axis positioning block 5530.

This structural design is ingenious. When the board lifting drive source 42 drives the board taking unit 541 to lift, the lifted board taking unit 541 vertically enters and exits the material frame. At this time, the first power source 5433 drives the movable limit plate 5432 to rotate to keep it aligned with the fixed limit plate 5431.
