Description

Technical Field

[0001] This utility model relates to the technical field of PCB board production and processing equipment, and in particular to a dust collection device for a cutting and grinding machine. Background Technology

[0002] During the PCB manufacturing process, the laminated PCBs require edge trimming using a cutting and grinding line. Dust is generated during this trimming process. In current technology, this dust is typically removed via a suction pipe installed next to the cutting blade; however, some dust still settles around the PCBs. When the PCBs are horizontally conveyed, this dust adheres to the rollers. This dust contains small amounts of copper particles, which can scratch the PCB surface, increasing the scrap rate. Furthermore, during PCB conveying, dust from the edges can fall onto the machine's sensors, triggering alarms and affecting the overall operation of the equipment.

[0003] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a dust collection device for a cutting and grinding machine.

[0005] The technical solution of this utility model is as follows: A dust collection device for a cutting and grinding machine is provided, including: a fixed frame, a lower pressure plate disposed at the bottom of the fixed frame, an upper pressure component disposed at the top of the fixed frame, a cutting and grinding mechanism disposed beside the fixed frame, and a dust collection mechanism disposed on the side of the fixed frame near the cutting and grinding mechanism. The upper pressure component is movably pressed against the lower pressure plate. The dust collection mechanism includes: an upper dust collection hood disposed on the fixed frame corresponding to the position of the upper pressure component, a lower dust collection hood disposed on the fixed frame corresponding to the position of the lower pressure plate, a dust collection interface connected to the upper and lower dust collection hoods, and a negative pressure dust collection device connected to the dust collection interface through a pipeline. The bottom of the upper dust collection hood and the top of the lower dust collection hood are respectively provided with dust collection ports.

[0006] Furthermore, the upper and lower dust hoods are connected on one or both sides of the fixed frame to form a U-shaped or ring-shaped structure.

[0007] Furthermore, the upper pressure plate and the lower pressure plate are respectively provided with a plurality of air blowing ports, and the air blowing ports are connected to an air blowing device through pipelines.

[0008] Furthermore, the bottom surface of the upper dust hood and the top surface of the lower dust hood are respectively provided with air regulating plates, which can be moved to cover the dust suction port.

[0009] Furthermore, the upper pressure assembly includes: a plurality of lifting cylinders connected to the fixed frame, an upper pressure support plate connected to the lifting cylinders, and an upper pressure plate disposed at the bottom of the upper pressure support plate. The lifting cylinders drive the upper pressure support plate to move up and down, causing the upper pressure plate to move toward or away from the lower pressure plate.

[0010] Furthermore, the cutting and grinding mechanism includes: a movable module disposed beside the fixed frame, a cutting and grinding frame disposed on the moving end of the movable module, and a cutting and grinding blade disposed on the cutting and grinding frame.

[0011] Furthermore, a dustproof belt is provided on the fixed frame, and a number of guide rollers are provided on the cutting and grinding mechanism corresponding to the dustproof belt. The dustproof belt extends forward from one end of the fixed frame, passes around the guide rollers in sequence, passes around the back side of the cutting and grinding mechanism, and is fixed to the other end of the fixed frame.

[0012] Furthermore, a discharge port is provided at the bottom of the fixed frame near the cutting and grinding mechanism. A number of discharge movable cylinders are provided on the fixed frame corresponding to the discharge port. A baffle is hinged to the output end of the discharge movable cylinder. The top or bottom of the baffle is hinged to the fixed frame. The discharge movable cylinder drives the baffle to move around the hinge position and cover the discharge port.

[0013] Furthermore, a discharge conveyor belt is provided below the fixed frame corresponding to the discharge port.

[0014] Furthermore, a waste collection trough is provided at the rear end of the discharge port.

[0015] By adopting the above solution, this utility model forms a closed cutting cavity on the fixed frame when the upper pressure component moves downward and presses against the PCB board. Therefore, when the upper and lower dust suction hoods perform negative pressure suction, the dust scattered in the closed cutting cavity can be effectively sucked out, avoiding residual dust from affecting the normal operation of other mechanisms or components, or causing pollution and damage to the product surface. At the same time, because a smaller closed cutting cavity is formed, the negative pressure suction generated by the upper and lower dust suction hoods can more stably suck up the dust scattered in the cavity, effectively ensuring the overall dust removal effect and improving the cleanliness of the PCB board after cutting.

[0019] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Please see Figure 1 , Figure 2 This utility model provides a dust collection device for a cutting and grinding machine, including: a fixed frame 1, a lower pressure plate 2 disposed at the bottom of the fixed frame 1, an upper pressure component 3 disposed at the top of the fixed frame 1, a cutting and grinding mechanism 4 disposed beside the fixed frame 1, and a dust collection mechanism 5 disposed on the side of the fixed frame 1 near the cutting and grinding mechanism 4. The upper pressure component 3 is movably pressed onto the lower pressure plate 2. The dust collection mechanism 5 includes: an upper dust collection hood 51 disposed on the fixed frame 1 corresponding to the position of the upper pressure component 3, a lower dust collection hood 52 disposed on the fixed frame 1 corresponding to the position of the lower pressure plate 2, a dust collection interface 53 connected to the upper dust collection hood 51 and the lower dust collection hood 52, and a negative pressure dust collection device 54 connected to the dust collection interface 53 through a pipeline. The bottom of the upper dust collection hood 51 and the top of the lower dust collection hood 52 are respectively provided with dust collection ports.

[0021] When cutting the PCB board, the two sides of the PCB board to be cut are placed on the lower pressure plates 2 of the cutting and grinding machines on both sides, and then the upper pressure assembly 3 is activated to press and fix the PCB board. Subsequently, the cutting and grinding mechanism 4 cuts and grinds the PCB board to complete the cutting work. Since a closed cutting cavity is formed on the fixed frame 1 when the upper pressure assembly 3 moves downward and presses against the PCB board, the negative pressure suction through the upper dust hood 51 and the lower dust hood 52 can effectively suck out the dust scattered in the closed cutting cavity, avoiding the residual dust from affecting the normal operation of other mechanisms or components, or causing pollution and damage to the product surface. Because a smaller closed cutting cavity is formed, the negative pressure suction generated by the upper dust hood 51 and the lower dust hood 52 can more stably suck up the dust scattered in the cavity, effectively ensuring the overall dust removal effect and improving the cleanliness of the cut PCB board.

[0022] In some embodiments, the upper dust hood 51 and the lower dust hood 52 are connected on one or both sides of the fixed frame 1, forming a U-shaped or ring-shaped structure. Independent upper and lower dust hoods 51 and 52 require connection via two sets of negative pressure suction devices 54, which occupies a significant amount of space in the overall equipment. However, by connecting one or both ends of the upper and lower dust hoods 51 and 52, forming a U-shaped or ring-shaped structure, a single set of negative pressure suction devices 54 can simultaneously provide the necessary negative pressure for both the upper and lower dust hoods 51 and 52, effectively saving space and reducing overall production and maintenance costs.

[0023] In some embodiments, the upper pressure plate and the lower pressure plate 2 are respectively provided with a plurality of air blowing ports, and the air blowing ports are connected to an air blowing device through pipelines. When the PCB board is cut and ground by the cutting and grinding mechanism 4, air is blown through the air blowing ports on the upper pressure plate and the lower pressure plate 2, thereby preventing dust generated during the cutting and grinding process from falling onto the PCB board. By blowing dust through the air blowing ports, it is easier for the dust to escape in the cutting cavity, thereby facilitating the upper dust suction hood 51 and the lower dust suction hood 52 to suck out the escaped dust by negative pressure, effectively improving the efficiency and effect of dust removal.

[0024] In some embodiments, the bottom surface of the upper dust hood 51 and the top surface of the lower dust hood 52 are respectively provided with air regulating plates 55, which movably cover the dust suction port. By adjusting the covering effect of the air regulating plates 55 on the dust suction port, the air intake volume is adjusted according to the dust suction pressure, thereby ensuring the overall negative pressure adsorption effect, ensuring that the dust generated during the cutting and grinding process can be removed, and ensuring the cleanliness of the PCB board edges.

[0025] In some embodiments, the upper pressing assembly 3 includes: a plurality of lifting cylinders 31 connected to the fixed frame 1, an upper pressing support plate 32 connected to the lifting cylinders 31, and an upper pressing plate 33 disposed at the bottom of the upper pressing support plate 32. The lifting cylinders 31 drive the upper pressing support plate 32 to move up and down, causing the upper pressing plate 33 to move toward or away from the lower pressing plate 2. After the edge of the PCB board to be cut is placed on the lower pressing plate 2, the lifting cylinders 31 are activated, causing the upper pressing support plate 32 to move downward, thereby pressing the PCB board firmly by the upper pressing plate 33, thus achieving the pressing and fixing of the PCB board and preventing the PCB board from shifting during the cutting and grinding process, which would affect the cutting and grinding effect.

[0026] In some embodiments, the cutting and grinding mechanism 4 includes: a movable module 41 disposed beside the fixed frame 1, a cutting and grinding frame 42 disposed on the moving end of the movable module 41, and a cutting and grinding blade 43 disposed on the cutting and grinding frame 42. During the cutting and grinding operation, the movable module 41 first moves the cutting and grinding frame 42 to the initial cutting and grinding position. After the cutting and grinding blade 43 is activated, the movable module 41 drives the cutting and grinding frame 42 to move, thereby cutting the PCB board using the cutting and grinding blade 43 and grinding the cut surfaces to achieve the cutting and grinding process of the PCB board.

[0027] In some embodiments, a dustproof belt 6 is provided on the fixed frame 1, and a plurality of guide rollers 61 are provided on the grinding mechanism 4 corresponding to the dustproof belt 6. The dustproof belt 6 extends forward from one end of the fixed frame 1, passes around the guide rollers 61 in sequence, passes around the back side of the grinding mechanism 4, and is fixed to the other end of the fixed frame 1. By providing the dustproof belt 6, dust generated during the grinding process can be prevented from escaping onto the moving module 41 of the grinding mechanism 4, thereby preventing abnormal movement of the moving module 41 and improving the overall cleanliness of the equipment and the stability of the equipment operation.

[0028] In some embodiments, a discharge port is provided at the bottom of the fixed frame 1 near the cutting and grinding mechanism 4. A plurality of discharge cylinders 71 are provided on the fixed frame 1 corresponding to the discharge port. A baffle 72 is hinged to the output end of each discharge cylinder 71. The top or bottom of the baffle 72 is hinged to the fixed frame 1. The discharge cylinders 71 drive the baffle 72 to move around the hinge position and cover the discharge port. During the cutting operation, the baffle 72 covers the discharge port, keeping the cutting cavity closed and ensuring the dust removal effect of the upper and lower dust hoods 51 and 52 on the dust in the cutting cavity. After the cutting and grinding operation and dust removal are completed, the discharge cylinders 71 are activated, causing the baffle 72 to rotate around the hinge position, exposing the discharge port, thereby discharging the cut edge material and waste through the discharge port.

[0029] In some embodiments, please refer to Figure 3 A discharge conveyor belt 73 is provided below the fixed frame 1 corresponding to the discharge port. After the board edge material and waste material are discharged from the discharge port, they fall onto the discharge conveyor belt 73 and are sent out by the discharge conveyor belt 73, which facilitates waste discharge.

[0030] In some embodiments, a waste collection trough 74 is provided at the rear end of the discharge port. The waste collection trough 74 can be directly located below the discharge port, so that when board edge material and waste are discharged from the discharge port, they will fall directly into the waste collection trough 74, thereby centrally recycling the waste. Alternatively, the waste collection trough 74 can be located at the rear end of the discharge conveyor belt 73, so that board edge material and waste are sent to the waste collection trough 74 for centralized recycling. This method can prevent dust raised when board edge material and waste fall from entering the cutting cavity through the discharge port, thus avoiding contamination of the cut PCB board.

[0031] In summary, this invention creates a closed cutting cavity on the fixing frame when the upper pressing component moves downward and presses against the PCB board. Therefore, negative pressure suction using the upper and lower dust hoods effectively removes dust from the closed cutting cavity, preventing residual dust from affecting the normal operation of other mechanisms or components, or causing contamination or damage to the product surface. Simultaneously, due to the smaller closed cutting cavity, the negative pressure suction generated by the upper and lower dust hoods can more stably extract dust from the cavity, effectively ensuring overall dust removal efficiency and improving the cleanliness of the cut PCB board.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
