Description

Technical Field

[0001] This utility model relates to the field of PCB board processing and production technology, and in particular to a feeding device for an automatic PCB board washing line. Background Technology

[0002] Soldering is a critical step in the PCB manufacturing process. Various solders and fluxes are used during soldering, leaving residues on the PCB surface afterward. Additionally, the production environment may contain dust, oil, and other contaminants. If these residues and contaminants are not removed, they can lead to short circuits, corrosion, and other problems during PCB use, severely impacting performance and reliability, and even shortening lifespan. Therefore, cleaning the PCB after soldering is an essential step in ensuring product quality.

[0003] Currently, PCB cleaning is typically carried out using automated PCB washing lines. These lines effectively remove residues and contaminants from the PCB surface through methods such as spraying, immersion, and ultrasonic cleaning. However, in existing technologies, PCBs are still largely placed and transported manually before entering the automated washing line. This manual operation cannot be efficiently integrated with automated cleaning equipment, resulting in a low overall automation level for the production line, failing to meet the demands of large-scale production, and severely impacting cleaning efficiency. Utility Model Content

[0004] To improve the automation and efficiency of the PCB board cleaning process, this application provides a feeding device for an automated PCB board cleaning line.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] A feeding device for an automatic PCB board washing line includes a frame, a tray is provided inside the frame, and a feeding component is provided above the tray. The feeding component transports the PCB boards on the tray to the conveyor belt of the automatic line.

[0007] The feeding assembly includes an adsorption component, a lifting component, and a translation component. The translation component is connected to the lifting component and drives the lifting component to move horizontally. The lifting component is connected to the adsorption component and drives the adsorption component to move vertically.

[0008] By employing the aforementioned device, the loading assembly, through the coordination of translation and lifting components, can move in both horizontal and vertical directions, accurately grasping PCB boards from the pallet and transporting them to the designated position, thus improving loading accuracy and efficiency. The PCB boards are firmly held by the suction components and remain stable during transport, preventing damage caused by shaking or falling, thereby enhancing production reliability and safety. The entire loading device is compact in structure and easy to operate, significantly reducing manual intervention, improving the overall automation level of the automatic PCB washing line, meeting the needs of large-scale production, reducing labor costs, and increasing production efficiency.

[0009] Preferably, the translation component includes a translation drive cylinder, a translation guide rod, and a moving box. The translation guide rod is fixed on the frame, the translation drive cylinder is installed at one end of the frame, and the moving box is connected to the output end of the translation drive cylinder.

[0010] By employing the aforementioned device, using a translational drive cylinder as the power source, and cooperating with the lifting and adsorption components, precise horizontal movement of the PCB board can be achieved. The translational drive cylinder provides stable power output, ensuring that the moving box moves smoothly and accurately along the translational guide rod.

[0011] Preferably, the lifting component includes a lifting drive cylinder, a drive shaft, and a slide rod. The lifting drive cylinder is disposed inside the movable box. One end of the drive shaft is connected to the output end of the lifting drive cylinder, and the other end is connected to the slide rod. Multiple sliders are connected to the slide rod.

[0012] By employing the aforementioned device, the lifting drive cylinder drives the slide bar to move precisely in the vertical direction, thereby accurately moving the suction components closer to or away from the PCB board, improving the precision of the pick-and-place operation. The drive shaft ensures the stability of the slide bar's movement, reducing PCB board damage or positioning deviations caused by slide bar swaying. The method of connecting multiple sliders to the slide bar allows for the simultaneous fixing of multiple suction components, enabling the gripping of multiple PCB boards in a single operation, significantly improving work efficiency.

[0013] Preferably, the adsorption component includes a suction cup, an air tube, and a vacuum generator. The vacuum generator is fixedly installed on the upper part of the frame, and the vacuum generator is connected to the suction cup via the air tube. The suction cup is connected to the slider.

[0014] By using the above-mentioned device, the suction cup works in conjunction with the vacuum generator to firmly adhere to the PCB board using the principle of negative pressure, ensuring that it will not fall or shift during transportation.

[0015] Preferably, a connecting piece is fixed to the end of the slider, and a connecting rod is provided on the connecting piece. The suction cup is connected to the connecting piece through the connecting rod.

[0016] Preferably, a buffer is provided between the connecting piece and the suction cup, and the buffer is sleeved on the outer periphery of the connecting rod.

[0017] By employing the aforementioned device, a connecting piece is fixed to the end of the slider and connected to the suction cup via a connecting rod. This effectively enhances the connection stability between the suction cup and the slider, ensuring that the suction cup maintains a stable posture during lifting and translation, preventing the PCB board from detaching due to vibration or impact. The buffer absorbs and mitigates the impact force generated during the adsorption and release of the PCB board, effectively reducing excessive pressure from the suction cup on the PCB board, thereby minimizing damage to the PCB board.

[0018] Preferably, a control panel is provided on the top of the frame, and the control panel is electrically connected to the vacuum generator, the translation drive cylinder, and the lifting drive cylinder.

[0019] By adopting the above-mentioned device, the working status of each component can be centrally managed and controlled through the control panel, reducing human intervention and improving work efficiency.

[0020] Preferably, the frame is provided with an installation plate, the tray is fixed on the installation plate, and the bottom of the tray is provided with a diagonal brace. One end of the diagonal brace is connected to the installation plate, and the other end is connected to the tray.

[0021] By adopting the above-mentioned device, the connection between the support plate and the mounting plate through the diagonal brace is more stable, thereby improving the structural stability of the entire device.

[0022] This application has the following beneficial effects:

[0023] 1. In this application, the loading assembly, through the cooperation of translation and lifting components, can move in both horizontal and vertical directions, thereby accurately grasping the PCB board on the pallet and transporting it to the designated position, improving loading accuracy and efficiency. The PCB board can be firmly adsorbed by the suction component and remain stable during transportation, avoiding damage caused by shaking or falling, thus improving production reliability and safety. The entire loading device has a compact structure and is easy to operate, significantly reducing manual intervention, improving the overall automation level of the automatic board washing line, meeting the needs of large-scale production, reducing labor costs, and improving production efficiency.

[0024] 2. In this application, a connecting piece is fixed to the end of the slider and connected to the suction cup via a connecting rod, effectively enhancing the connection stability between the suction cup and the slider. This ensures that the suction cup maintains a stable posture during lifting and translation, preventing the PCB board from falling off due to vibration or impact. The buffer can absorb and mitigate the impact force generated during the adsorption and release of the PCB board, effectively reducing excessive pressure from the suction cup on the PCB board, thereby reducing damage to the PCB board.

[0030] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0031] A feeding device for an automated PCB washing line, such as Figure 1 As shown, the system includes a frame 1, a tray 2, and a loading assembly 3. The frame 1 is placed at the input end of the conveyor belt in the automated PCB washing line. An mounting plate 11 is installed inside the frame 1, and the tray 2 is fixed to the mounting plate 11. Two diagonal braces 21 are fixed to the bottom of the tray 2 to improve its stability. The loading assembly 3 is installed above the tray 2. The loading assembly 3 transports the PCBs from the tray 2 to the conveyor belt, automating the loading process and significantly reducing the dwell time of the PCBs during loading. This improves the efficiency of the entire cleaning process and better meets the demands of large-scale production.

[0032] Specifically, such as Figure 1-2 As shown, the feeding assembly 3 includes an adsorption component 31, a lifting component 32, and a translation component 33. The translation component 33 includes a translation drive cylinder 331, translation guide rods 332, and a moving box 333. The translation drive cylinder 331 is mounted at one end of the frame 1, serving as the power source for driving the moving box 333 to move horizontally. Two translation guide rods 332 are provided, both penetrating the moving box 333, allowing the moving box 333 to move along the translation guide rods 332 under the action of the translation drive cylinder 331, thus improving stability.

[0033] like Figure 1-2 As shown, the lifting component 32 is located above the pallet 2. The lifting component 32 includes a lifting drive cylinder 321, a drive shaft 322, and a slide rod 323. The lifting drive cylinder 321 is installed inside the moving box 333, and its output end is connected to the drive shaft 322. The other end of the drive shaft 322 is connected to the slide rod 323 to drive the slide rod 323 to move up and down. Two drive shafts 322 are provided to ensure the stability of the slide rod 323's lifting movement and reduce PCB board damage or positioning deviation caused by slide rod 323 wobbling. In addition, multiple sliders 324 are slidably connected to the slide rod 323. In this application, five sliders 324 are provided, which can simultaneously fix multiple suction components 31, enabling the suction of multiple PCB boards in one operation, further improving work efficiency.

[0034] like Figure 1-2 As shown, the adsorption component 31 consists of a suction cup 311, an air tube 312, and a vacuum generator 313. The vacuum generator 313 is mounted on the frame 1, and the suction cup 311 is mounted on the slider 324. The vacuum generator 313 and the suction cup 311 are connected via the air tube 312. During operation, the vacuum generator 313 generates negative pressure, enabling the suction cup 311 to firmly adsorb the PCB board, effectively preventing the PCB board from falling or being damaged during loading due to unstable adsorption. Since the suction cup 311 is the part that directly contacts the PCB board, this embodiment uses a vacuum sponge suction cup 311, which can prevent damage to sensitive circuits and avoid introducing new sources of contamination.

[0035] Furthermore, such as Figure 2-3 As shown, to reduce the pressure of the suction cup 311 on the PCB board and effectively enhance the connection stability between the suction cup 311 and the slider 324, connecting plates 325 are fixed to both ends of the slider 324 by bolts. A connecting rod 326 is provided on the connecting plate 325, and the suction cup 311 is connected to the connecting plate 325 through the connecting rod 326. A buffer 327 is sleeved on the outer periphery of the connecting plate 325 to absorb and mitigate the impact force generated during the adsorption and release of the PCB board, effectively reducing excessive pressure from the suction cup 311 on the PCB board and thus reducing damage to the PCB board. In this embodiment, the buffer 327 is a spring.

[0036] In addition, such as Figure 1-2 As shown, in order to further improve the automation level of the entire system, a control panel 4 is set on the top of the frame 1. The control panel 4 is electrically connected to the vacuum generator 313, the translation drive cylinder 331, and the lifting drive cylinder 321 through wires, so as to realize centralized control, simplify the operation process, and improve work efficiency.

[0037] Working principle: During operation, the lifting drive cylinder 321 drives the slide bar 323 downward, bringing the suction cup 311 closer to the PCB board. The vacuum generator 313 provides suction force to the suction cup 311, enabling it to adhere to the PCB board. The lifting drive cylinder 321 then lifts the suction cup 311. Next, the translation drive cylinder 331 moves the moving box 333 towards the conveyor belt, placing the PCB board on the conveyor belt. This effectively improves the overall automation level of the automatic PCB washing line, meets the needs of large-scale production, reduces labor costs, and increases production efficiency.
