Description

Technical Field

[0001] This utility model relates to the field of laser processing technology, specifically to a laser cleaning machine. Background Technology

[0002] In the field of flexible printed circuit board (FPC) manufacturing and repair, FPCs are widely used in precision products such as smartphones, wearable devices, and automotive electronics due to their characteristics of being "thin, flexible, and having high circuit density." During their production processes (such as SMT soldering and cover film lamination) and repair processes, contaminants such as solder slag, flux, cover film residue, and copper foil oxide layers can easily remain on the surface. These contaminants can directly lead to problems such as poor soldering, short circuits, and bonding failures in subsequent mounting, seriously affecting the electrical performance and reliability of FPCs.

[0003] In existing technologies, lasers are generally used to clean FPCs. However, traditional laser cleaning equipment often adopts a single-station structure. When the fixture is in the cleaning process, it is necessary to wait for the cleaning to be completed before loading or unloading can be performed. The overall processing pace is slow and the processing efficiency is low. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this utility model provides a laser cleaning machine that improves processing efficiency by using two staggered workstations.

[0020] Reference Figures 1-9This utility model provides a laser cleaning machine, including a frame and a loading assembly 100, a conveying assembly, a processing assembly, and a unloading assembly 200 mounted on the frame. The loading assembly 100 and the unloading assembly 200 are respectively disposed on both sides of the processing assembly. The loading assembly 100 is used to provide FPC boards to be cleaned, and the unloading assembly 200 is used to collect cleaned FPC boards. The processing assembly includes a base 311, a processing platform 310 disposed on the base 311, and a laser system 320. The processing platform 310 has two components, namely a first processing platform and a second processing platform. The laser system 320 includes a first laser and a second laser. The first laser is located above the first processing platform to perform laser cleaning on the FPC boards on the first processing platform, and the second laser is located above the second processing platform. Above the processing platform, laser cleaning is performed on the FPC boards on the second processing platform. The handling assembly includes a support frame 410, a first linear module 440, a second linear module 450, a loading robot 420, and an unloading robot 430. Both the first linear module 440 and the second linear module 450 are linear motors. The first linear module 440 and the second linear module 450 are mounted on the support frame 410 along the X-axis. The loading robot 420 is located at the drive end of the first linear module 440 to transport the FPC boards to be cleaned supplied by the loading assembly 100 to the first and second processing platforms. The unloading robot 430 is located at the drive end of the second linear module 450 to transport the processed FPC boards from the first and second processing platforms to the unloading assembly 200. It can be understood that while one processing platform 310 is in laser processing mode, the other processing platform 310 is in loading or unloading mode, thus achieving continuous laser cleaning operation and improving production efficiency.

[0021] In this embodiment, the feeding component 100 and the unloading component 200 have the same structure. Taking the feeding component 100 as an example, refer to... Figures 2-4The loading assembly 100 includes a fixed frame 130, a sliding frame 120, a carrier pallet 110, and a pallet lifting module 150. The fixed frame 130 is fixedly connected to the frame. The sliding frame 120 is slidably connected to the fixed frame 130 via a drawer guide rail 140. A limiting structure is provided on the sliding frame 120. The carrier pallet 110 is slidably connected to the limiting structure in the vertical direction. The pallet lifting module 150 is disposed on the fixed frame 130. When the carrier pallet 110 moves directly above the pallet lifting module 150, the pallet lifting module 150 can drive the carrier pallet 110 to rise and fall. FPC boards are stacked in the carrier pallet 110. The pallet lifting module 150 drives the carrier pallet 110 to move upward to facilitate the loading and unloading of FPC boards. The carrier pallet 110 can be moved out of the frame by pulling the sliding frame 120, thereby facilitating the loading and unloading of the carrier pallet 110.

[0022] Furthermore, the limiting structure includes multiple limiting plates 160, which form a limiting space for accommodating the vehicle pallet 110, ensuring stable lifting and lowering of the vehicle pallet 110, and is simple in structure and low in cost.

[0023] Furthermore, the pallet lifting module 150 includes a mounting frame 151, a connecting frame 152, a lifting plate 153, and a lifting drive component 154. The mounting frame 151 is fixedly connected to the fixed frame 130. The connecting frame 152 is slidably connected to the mounting frame 151 in the vertical direction via a linear guide rail. The lifting plate 153 is disposed on the top of the connecting frame 152. The lifting drive component 154 is a linear motor. The lifting drive component 154 is mounted on the mounting frame 151, and the moving part of the lifting drive component 154 is connected to the connecting frame 152. When the sliding frame 120 is pushed into the machine frame, the carrier pallet 110 moves to directly above the lifting plate 153. The lifting drive component 154 drives the lifting plate 153 to move upward, thereby lifting the carrier pallet 110 and causing the carrier pallet 110 to move upward.

With the cooperation of the first X-axis module 324 and the first Y-axis module 312, the first laser head 325 performs laser cleaning on the FPC board on the first vacuum adsorption fixture 313. Similarly, with the cooperation of the second X-axis module 322 and the second Y-axis module 314, the second laser head 323 performs laser cleaning on the FPC board on the second vacuum adsorption fixture 315.

[0025] Specifically, refer to Figure 6 The vacuum adsorption fixture includes an adsorption cavity 3131. A negative pressure tube 3132 is connected to the bottom of the adsorption cavity 3131. A plurality of adsorption holes 3133 are provided on the top of the adsorption cavity 3131. A vacuum pump is connected to the negative pressure tube 3132 to evacuate the adsorption cavity 3131, thereby generating a negative pressure adsorption force at the adsorption holes 3133, which adsorbs and fixes the FPC board on the adsorption cavity 3131 to facilitate the laser cleaning of the FPC board.

[0026] In this embodiment, the loading robot 420 and the unloading robot 430 have the same structure. Taking the loading robot 420 as an example, refer to...

The suction nozzle structure includes a suction nozzle mounting frame 424 and several suction nozzles 425 mounted on the suction nozzle mounting frame 424. The suction nozzle mounting frame 424 is fixedly connected to the lifting connecting frame 422. Thus, the extension and retraction of the cylinder 423 can drive the suction nozzles 425 to move up and down, facilitating the loading and unloading of FPC boards.
