Description

Technical Field

[0001] This invention pertains to technologies related to circuit board manufacturing, and particularly relates to a circuit board chemical cleaning device. Background Technology

[0002] Nickel-palladium-gold (CPG) is an important surface treatment process for circuit boards. Due to its excellent corrosion resistance, solderability, and bonding performance, current CPG technology is mainly used in the production of optical module circuit boards. The nickel-palladium-gold process on the surface of optical module circuit boards typically requires immersing the circuit boards in various chemical solutions. In existing nickel-palladium-gold processes for optical module circuit boards, due to the thin and brittle structure of the circuit boards (especially those 0.5mm and below) and insufficient rigidity, manual handling is commonly used. However, problems such as bending, board slippage, and board curling easily occur during manual handling and roller transfer. Furthermore, the automation level of manual handling is low. During the manual handling and immersion process in the chemical solutions, the optical module circuit boards are prone to breakage and contamination, severely impacting the production quality. Additionally, the nickel-palladium-gold solutions can have certain effects on human health, potentially causing safety accidents during production. Summary of the Invention

Detailed Implementation

[0019] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0020] Example 1: like Figures 1-2 As shown, this application discloses a circuit board chemical cleaning device, comprising: The transport device 1 includes a first conveyor belt 11 for transporting workpieces; The first transfer device 2 is located at the exit of the first conveyor belt 11. The first transfer device 2 includes a multi-axis manipulator 21 and a suction cup mechanism 22. The suction cup mechanism 22 is located at the free end of the multi-axis manipulator 21. The first transfer device 2 is used to adsorb and rotate the workpiece. The second transfer device 3 is disposed adjacent to the first transfer device 2. The second transfer device 3 includes a second conveyor belt 31, a first lifting mechanism 32, and a clamping mechanism 33. The clamping mechanism 33 is mounted on the first lifting mechanism 32 to lift and clamp the workpiece on the suction cup mechanism 22. The inlet of the second conveyor belt 31 is located at the bottom of the clamping mechanism 33. A transfer frame 34 is provided on the second conveyor belt 31 to support the workpiece clamped on the clamping mechanism 33. The medicine soaking device 4 includes multiple medicine soaking mechanisms 41, a moving mechanism 42, a second lifting mechanism 43, and a lifting mechanism 44. The multiple medicine soaking mechanisms 41 are arranged in sequence at the outlet of the second conveyor belt 31. The moving mechanism 42 is located above the medicine soaking mechanism 41. The second lifting mechanism 43 is located on the moving mechanism 42 and moves. The lifting mechanism 44 is located on the second lifting mechanism 43 and moves up and down. The lifting mechanism 44 engages with the transfer frame 34 and drives the transfer frame 34 to move up and down.

[0021] Specifically, the transport device 1 includes a first transport belt 11, which can be a roller conveyor or a belt conveyor. To prevent the circuit board of the ultra-thin optical module from breaking during transport, a rigid plate can be provided on the first transport belt 11 for placing the thin circuit board of the optical module. A first transfer device 2 is fixed at the exit of the first transport belt 11. The first transfer device 2 includes a multi-axis manipulator 21 and a suction cup mechanism 22 located at the free end of the multi-axis manipulator 21. The suction cup mechanism 22 can adsorb the circuit board of the optical module through suction ports, and the multi-axis manipulator 21 adjusts the posture of the workpiece for non-manual transfer, avoiding damage to the circuit board of the optical module caused by manual labor or roller conveyors during the transfer. The first transfer device 2 is used to rotate the workpiece so that the horizontal optical module thin plate can rotate the workpiece 90° to a vertical position. A second transfer device 3 is located adjacent to the first transfer device 2 and is used to clamp the vertically positioned workpiece. The clamping mechanism 33 is mounted on the first lifting mechanism 32 and moves up and down. After the vertical workpiece is clamped by the clamping mechanism 33, it is placed into the transfer frame 34 on the second conveyor belt 31. This avoids placing the workpiece directly on the conveyor belt and also maintains the vertical position of the workpiece for vertical immersion. The chemical immersion device 4 includes multiple chemical immersion mechanisms 41 to hold different chemicals, such as water, nickel-palladium-gold related chemicals, etc. A moving mechanism 42 is provided above the chemical immersion mechanism 41. In some embodiments, it can be a flyover structure. The second lifting mechanism 43 moves with the moving mechanism 42. A lifting mechanism 44 moves up and down on the second lifting mechanism 43. The lifting mechanism 44 engages with the moving frame and moves up and down with the second lifting mechanism 43 to lift the moving frame. The moving mechanism 42 moves the moving frame above different immersion mechanisms, where it is immersed by the second lifting mechanism 43 and then lifted and moved to the next immersion mechanism for further immersion.

[0022] The circuit board cleaning equipment of the present invention includes a transport device 1, a first transfer device 2, a second transfer device 3, and a chemical soaking device 4. The transport device 1 transports circuit board workpieces. The first transfer device 2 uses a multi-axis manipulator 21 and a suction cup mechanism 22 to adsorb and rotate the workpieces. The second transfer device 3 clamps the rotated workpieces using a clamping mechanism 33 and lifts them using a first lifting mechanism 32, so that the workpieces are placed within a transfer frame 34. The workpieces are moved to the chemical soaking device 4 via the transfer frame 34. The chemical soaking device 4 lifts the transfer frame 34 using a lifting mechanism 44, and then lifts and extends the transfer frame 34 into the chemical soaking device 41 using the second lifting mechanism 43. This application can avoid safety accidents caused by manual transfer through a fully automated transfer method. At the same time, the transfer frame 34 also avoids damage to the circuit boards of optical modules caused by manual and roller transfer during nickel-palladium-gold surface treatment of the circuit boards.

[0023] In some embodiments, the suction cup mechanism 22 includes a suction frame 221 and a plurality of suction head assemblies 222. The suction frame 221 is disposed at the free end of the multi-axis manipulator 21, and the suction head assemblies 222 are disposed at the bottom of the suction frame 221. After the suction head assemblies 222 adsorb the horizontally positioned workpiece, the multi-axis manipulator 21 sets the workpiece to a vertical position.

[0025] In some embodiments, the suction cup mechanism 22 includes a suction frame 221 and a plurality of suction head assemblies 222. The suction frame 221 is disposed at the free end of the multi-axis manipulator 21, and the suction head assemblies 222 are disposed at the bottom of the suction frame 221.

These vacuum head assemblies are fixed with screws, and the suction ports of the vacuum heads, along with the multiple suction head assemblies 222, form a suction surface. During suction, the suction surface adheres to the surface of the workpiece, allowing for more stable suction of the workpiece from the first conveyor belt 11. After suctioning the workpiece, the multi-axis robot 21 rotates the workpiece by 90° so that the clamping mechanism 33 can clamp it.

[0027] In some embodiments, the second transport belt 31 includes a first transport section 311 and a second transport section 312. The first transport section 311 is provided with a first transport guide rail 3111 and a transport platform 3112. The transport platform 3112 moves on the first transport guide rail 3111. One end of the first transport guide rail 3111 is located at the bottom of the clamping mechanism 33, and the other end of the first transport guide rail 3111 is located at the entrance of the second transport section 312. The outlet of the second transport section 312 is connected to the medicine soaking mechanism 41.

[0028] Specifically, the second transport belt 31 is divided into a first transport section 311 and a second transport section 312. The first transport section 311 is provided with a first transport guide rail 3111 and a transport platform 3112. The first transport guide rail 3111 moves on the transport platform 3112. One end of the first transport guide rail 3111 is located at the bottom of the clamping mechanism 33. The empty transfer frame 34 can be transported to the bottom of the clamping mechanism 33 through the transport platform 3112. With the cooperation of the clamping mechanism 33 and the first lifting mechanism 32, the workpiece is placed in the empty transfer frame 34. After the workpiece is loaded, the fully loaded transfer frame 34 is moved to the other end of the first transport guide rail 3111 through the transport platform 3112 and connected to the second transport section 312, so that the transfer frame 34 moves through the second transport section 312 to the outlet of the second transport section 312 and is soaked in the chemical solution by the chemical solution soaking device 4.

[0029] In some embodiments, a fixed fence 325 is provided below the clamping mechanism 33 to engage the transfer frame 34.

Furthermore, a first lifting drive 324 is provided, which can be a drive belt to move the first lifting movable seat 322 arranged on the first lifting movable guide rail. The clamping mechanism 33 includes a clamping drive 331 and a clamping claw 332. The clamping drive 331 can be a clamping motor, which drives the clamping claw 332. The clamping claw 332 is used to clamp one side of the workpiece. After the clamping claw 332 clamps the workpiece, the vacuum suction head of the adsorption mechanism releases the workpiece, allowing the workpiece to move with the first lifting mechanism 32 and descend into the transfer frame 34 at the bottom. After the workpiece is placed in the transfer frame 34, it is released by the clamping mechanism 33. This method avoids manual placement and also prevents damage to the workpiece.

[0033] In some embodiments, the first lifting mechanism 32 further includes a lateral movement component 333, and a clamping drive 331 is disposed on the lateral movement component 333 to cause the clamping claw 332 to move laterally through the lateral movement component 333.
