Technical Field
[0001] This utility model relates to the field of dustproof technology, specifically a dustproof cover and circuit board processing equipment using the same. Background Technology
[0002] Because CCL or PCB circuit boards are relatively delicate components, a high-standard cleanroom environment is required during production to ensure that dust does not cause problems such as open circuits, short circuits, or solder mask contamination. Existing dust prevention methods usually involve placing the equipment directly in a cleanroom, but the processing equipment can only be used in that cleanroom and is inconvenient to move; in addition, the dust prevention effect of a cleanroom on an individual machine is weak and it is easily affected by surrounding equipment, so dust still tends to scatter throughout the manufacturing process. Utility Model Content
[0003] The purpose of this utility model is to propose a dust cover and circuit board processing equipment using it, in order to solve the technical problems that existing circuit board production dust prevention is mostly placed in a cleanroom, the equipment is inconvenient to move out of the cleanroom, and the dust prevention effect of the cleanroom is poor.
[0004] To achieve the above objectives, this utility model proposes a dust cover for covering circuit board processing equipment. The dust cover includes:
[0005] Cover;
[0006] An air filtration mechanism is disposed at the top of the enclosure and is used to filter the air entering the enclosure.
[0007] A base plate, used to enclose the cover;
[0008] A dust collection mechanism, at least one of which is disposed on the base plate and is used to remove dust from inside the cover to outside the cover.
[0009] Preferably, there are two dust collection mechanisms, and the two dust collection mechanisms are respectively installed on both sides of the base plate.
[0010] Preferably, the dust collection mechanism includes a dust collection hood, a vacuum cleaner, and an exhaust pipe. The vacuum cleaner is used to draw air from inside the hood. The vacuum cleaner is mounted on the hood. One end of the vacuum cleaner is connected to the dust collection hood, and the other end is connected to the exhaust pipe. The end of the exhaust pipe is connected to the outside to discharge the air drawn by the vacuum cleaner to the outside.
[0011] Preferably, the diameter of the dust hood gradually increases from the end closer to the vacuum cleaner to the end farther away from the vacuum cleaner to form a trumpet-shaped dust hood.
[0012] In addition, this utility model also discloses a circuit board processing equipment, including the dust cover described in any of the above claims, and further including: a frame, the cover being mounted on the frame, and the base plate being mounted on the frame;
[0013] A feeding mechanism is provided on the frame, and the feeding mechanism is located inside the cover.
[0014] Preferably, the frame is provided with a plurality of feeding mechanisms, which respectively feed at least two kinds of raw material plates;
[0015] It also includes a stacking mechanism disposed on the frame, the stacking mechanism being used to stack at least two types of raw material plates to obtain a PCP plate, the stacking mechanism being located inside the cover.
[0016] Preferably, it also includes a transport mechanism, which is movably mounted on the frame and located inside the cover. The transport mechanism is used to transport the raw material plates of the feeding mechanism to the stacking mechanism respectively.
[0017] The transport mechanism includes a core board transport assembly and a suction assembly, which are respectively mounted on the frame. The core board transport assembly is used to transport the core board to the stacking mechanism, and the suction assembly is used to suction the PP board and transport it to the stacking mechanism.
[0018] Preferably, the frame is further provided with a transplanting mechanism, which is used to transport the stacked PCP boards to the outside, and the transplanting mechanism is located inside the cover.

[0022] This utility model discloses a dust cover and a circuit board processing equipment using the same, which has the following beneficial effects: by installing a cover and a base plate on the equipment, the equipment is relatively isolated from the outside. An air filtration mechanism is set at the top of the cover, and a dust collection mechanism is set at the bottom. The air filtration mechanism blows the purified air from top to bottom, while the dust collection mechanism at the bottom simultaneously draws in air to form a pressure difference. The airflow always maintains a top-to-bottom flow path, which suppresses the floating of dust particles inside the cover. The dust that was originally present in the cover or was generated during processing is collected at the bottom and then drawn out by the dust collection mechanism and discharged to the outside with the movement of the airflow. This ensures that the products to be processed inside the cover are basically in a dust-free environment with a high degree of cleanliness. Attached Figure Description

[0030] like Figure 1 As shown, a dust cover is used to cover the outside of circuit board processing equipment, the dust cover comprising:
[0031] Cover 1;
[0032] An air filtration mechanism 2 is disposed at the top of the cover 1, and the air filtration mechanism 2 is used to filter the air entering the cover 1;
[0033] Base plate 3, used to enclose the cover 1;
[0034] Dust collection mechanism 4, at least one of the dust collection mechanisms 4 is disposed on the base plate 3 and is used to remove dust from inside the cover 1 to outside the cover 1.
[0035] This dust cover is suitable for use on processing equipment that requires isolation from the outside environment, such as those demanding a strictly clean environment. It is particularly suitable for use on circuit board processing equipment.
[0036] Specifically, the dust cover includes a cover body 1 and a base plate 3 installed on the equipment. Together, they form a sealed cavity, relatively isolating the equipment from the outside world and preventing dust flying outside from entering the equipment. An air filter mechanism 2 is installed above the cover body 1, and a dust collection mechanism 4 is installed below. The air filter mechanism 2 blows purified air from top to bottom, while the dust collection mechanism 4 simultaneously draws in air, creating a pressure difference. The airflow always maintains a top-to-bottom flow path, suppressing the floating of dust particles inside the cover body 1. This ensures that the dust originally present in the cover body 1 or the dust generated during processing is collected at the bottom and then drawn out by the dust collection mechanism 4 and discharged to the outside by the airflow, thereby ensuring that the products to be processed inside the cover body 1 are in a basically dust-free environment with a high degree of cleanliness.
[0037] The dust cover installed on the equipment has good sealing performance and dust prevention effect. It is not easily affected by other surrounding machines, has good independence, and can be moved synchronously with the equipment to the required position, making it more adaptable. In addition, the continuously downward airflow can also play a certain role in heat dissipation for the processing equipment.
[0038] Furthermore, there are two dust collection mechanisms 4, and the two dust collection mechanisms 4 are respectively installed on both sides of the base plate 3.
[0039] To improve the air extraction efficiency of the dust collection mechanism 4, this embodiment provides two dust collection mechanisms 4 on the base plate 3 of the protective cover. The two dust collection mechanisms 4 are located on both sides of the base plate 3, resulting in a larger suction range. In other embodiments, the number of dust collection mechanisms 4 can be adjusted according to actual needs, such as providing one, three, or more dust collection mechanisms 4.
[0040] Furthermore, the dust collection mechanism 4 includes a dust collection hood 41, a vacuum cleaner 42, and an exhaust pipe 43. The vacuum cleaner 42 is used to draw air from inside the hood 1. The vacuum cleaner 42 is mounted on the hood 1. One end of the vacuum cleaner 42 is connected to the dust collection hood 41, and the other end is connected to the exhaust pipe 43. The end of the exhaust pipe 43 is connected to the outside to discharge the air drawn by the vacuum cleaner 42 to the outside.
[0041] In the dust collection mechanism 4, the vacuum cleaner 42 continuously draws air from the cover 1. The air enters the vacuum cleaner 42 from the end of the dust cover 41, and the vacuum cleaner 42 discharges the drawn air to the outside of the cover 1 / equipment through the exhaust pipe 43.
[0042] Furthermore, the diameter of the dust hood 41 gradually increases from the end closer to the vacuum cleaner 42 to the end farther away from the vacuum cleaner 42, forming a trumpet-shaped dust hood 41. The preferred shape of the dust hood 41 is trumpet-shaped, with a larger diameter at the air intake end and a smaller diameter at the end connected to the vacuum cleaner 42. This allows the suction end of the dust hood 41 to cover a wider range of air, resulting in better dust collection. In another embodiment, the dust hood 41 may also be cylindrical or other shapes.
[0043] In addition, this utility model also proposes a circuit board processing equipment, including the dust cover described in any of the above claims, and further including: a frame 5, the cover 1 being mounted on the frame 5, and the base plate 3 being mounted on the frame 5;
[0044] The frame 5 is provided with at least one feeding mechanism, which is located inside the cover 1.
[0045] The aforementioned dust cover is detachably mounted on the frame 5 for easy access. When a dust-free environment is required, after installing the cover 1 on the frame 5, the air filter mechanism 2 and the dust collection mechanism 4 can be activated to remove the dust inside the cover 1. In addition, the frame 5 is also equipped with a feeding mechanism, which can feed single or multiple raw material boards (such as core boards and / or PP boards) for circuit boards, facilitating subsequent processing of the raw materials.
[0046] Furthermore, the frame 5 is provided with a plurality of feeding mechanisms, which respectively feed at least two kinds of raw material plates;
[0047] It also includes a stacking mechanism, which is disposed on the frame 5. The stacking mechanism is used to stack at least two kinds of raw material plates to obtain a PCP plate. The stacking mechanism is located inside the cover 1.
[0048] The circuit board processing equipment in this solution also includes a stacking mechanism. First, multiple feeding mechanisms feed different types of raw material boards, and then the stacking mechanism stacks the various raw material boards to obtain the final product - PCP board. The enclosure 1 covers both the feeding mechanism and the stacking mechanism to ensure that the processing is carried out in a dust-free environment.
[0049] Furthermore, it also includes a transport mechanism, which is movably mounted on the frame 5. The transport mechanism is located inside the cover 1 and is used to transport the raw material plates of the feeding mechanism to the stacking mechanism respectively.
[0050] The transport mechanism includes a core board transport assembly and a suction assembly 6, which are respectively mounted on the frame 5. The core board transport assembly is used to transport the core board to the stacking mechanism, and the suction assembly 6 is used to suction the PP board and transport it to the stacking mechanism.
[0051] The core board and PP board in the transport mechanism are transported to the stacking mechanism by the core board transport assembly and the suction assembly 6, respectively. The core board and PP board are then loaded by the feeding mechanism and transported to the stacking mechanism by the transport mechanism. The stacking mechanism then stacks the PP board, core board, and PP board to obtain the PCP board. Because of the cover 1, the feeding mechanism, transport mechanism, and stacking mechanism are isolated from the outside environment, which provides a good dust protection effect during circuit board processing and results in a higher quality PCP board.
[0052] Furthermore, the frame 5 is also equipped with a transfer mechanism 7, which is used to transport the stacked PCP boards to the outside. The transfer mechanism 7 is located inside the cover 1. In addition to the above-mentioned mechanisms, this embodiment also adds a transfer mechanism 7, which can transport the produced PCP boards to the outside for the next process.
[0053] Furthermore, the transplanting mechanism 7 includes a mounting bracket 71, a Y-axis moving component 72, a Z-axis moving component 73, and a clamping component 74. The mounting bracket 71 is mounted on the frame 5, the Y-axis moving component 72 is mounted on the mounting bracket 71, the Z-axis moving component 73 is mounted on the Y-axis moving component 72, and the clamping component 74 is mounted on the Z-axis moving component 73.
[0054] The various components in the transplanting mechanism 7 are mainly set on the mounting bracket 71. The Y-axis moving component 72 and Z-axis moving component 73 set on the mounting bracket 71 ensure that the clamping component 74 can move freely along the Y-axis and / or Z-axis to transport the PCB board to different positions. During the movement, the PCB board is clamped by the clamping component 74.
[0055] In other embodiments, an X-axis moving component may also be mounted on the mounting bracket 71, or the mounting bracket 71 may be set on the X-axis moving component to further expand the moving range of the clamping component 74 in this solution. The X-axis moving component, Y-axis moving component 72, or Z-axis moving component 73 may be composed of mechanisms such as motors, gears, racks, slide rails, and sliders, or may be composed of a motor and a lead screw structure.
[0056] Furthermore, the feeding mechanism includes a first feeding component and a plurality of second feeding components 8, wherein the first feeding component and the second feeding components 8 are respectively disposed on the frame 5;
[0057] The first feeding component is used to feed the core board, and the second feeding component 8 is used to feed the PP board.
[0058] Specifically, the raw materials in this solution include core boards and PP boards. The first feeding assembly and the second feeding assembly 8 are used to feed the core boards and PP boards, respectively. Two second feeding assemblies 8 are provided on the frame 5. This is mainly because multiple PP boards are needed when a PCB board is stacked. Therefore, multiple second feeding assemblies 8 can improve the feeding efficiency of PP boards and reduce the processing cycle of PCB boards.
[0059] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
