Description
TECHNICAL FIELD
[0001] The utility model relates to PCB board processing technical field, specifically point to a kind of PCB board baking equipment with waste gas treatment. BACKGROUND
[0002] PCB board, namely printed circuit board, is the conductive plate made of insulating substrate, with predetermined electrical circuit pattern, and is called the "nerve center" of electronic equipment. It forms conductive circuit on insulating substrate through printing, etching and other processes, and is used to support electronic components and realize electrical connection. Its material is mainly glass fiber, epoxy resin, etc., with characteristics of stable structure and good insulation. From simple electronic watch to complex computer motherboard, PCB board is widely used in communication, consumer electronics, automotive electronics and other fields, not only provides physical support for electronic components, but also guarantees stable transmission of signals with precise circuit layout, and is one of the core components of modern electronic industry.
[0003] In electronic equipment maintenance and repair work, hot air baking is a common method for disassembling PCB board electronic components. When repairing, hot air gun is used to control temperature, and the component soldering point area is uniformly heated to melt solder through high temperature to disconnect the component and circuit board. However, this operation has two problems: first, when heating, PCB board substrate and component packaging materials will release irritating odor, which may contain harmful substances, and long-term inhalation will affect respiratory health and even cause chronic hidden danger; second, even if the solder is melted, some components are difficult to remove easily due to dense pin design or long-term use of pin oxidation, and improper force may cause PCB board tearing, solder pad falling off or damaging adjacent components, increasing repair difficulty and component damage risk. UTILITY MODEL CONTENTS
[0004] The utility model is to solve the above various problems, and proposes a kind of PCB board baking equipment with waste gas treatment, which can extract and remove harmful and unpleasant gas, protect health, and assist in disassembling electronic components by knocking PCB board.
[0005] To solve the above technical problems, the utility model provides a technical scheme: a kind of PCB board baking equipment with waste gas treatment, comprising:
[0006] The baking rack includes a carrier plate and a protective cover, the protective cover is fixed on the carrier plate, and the opening faces forward, the carrier plate is provided with a hollow slot, a pull-out box is slidably arranged in the hollow slot, and the upper wall of the carrier plate is a mesh plate;
[0007] The knocking structure includes a reversible motor, a crank and a knocking head, the reversible motor is fixed inside the protective cover, the crank is fixed on the output end of the reversible motor, and the knocking head is fixed on the extension end of the crank;
[0008] The suction pipe is fixed on the upper side of the protective cover, and the lower end of the suction pipe extends into the inside of the protective cover and is arranged towards the baking rack.
[0009] Further, the four corners of the lower side of the carrier plate are provided with supporting legs, and the bottom surface of the supporting legs is provided with a foot pad.
[0010] Further, the upper end of the front side of the protective cover is provided with a transparent protective plate.

[0013] Further, the knocking head is a spherical rubber material.
[0014] Further, the lower end of the suction pipe is integrally provided with a horn-shaped suction head.

The upper end of the suction pipe is fixed, and the lower end is provided with a horn-shaped suction head, which can expand the suction range, quickly suck the toxic and unpleasant gas generated in the baking process, and discharge through the subsequent treatment system, thereby protecting the health of the operator.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings.
[0023] Combined with appendix Figure 2 A PCB board baking device with exhaust gas treatment includes: a baking rack, including a carrier plate 1 and a protective cover 2. The carrier plate 1 is provided with four legs 8 at the lower corners. The bottom surface of the legs 8 is provided with foot pads, which can stably support the device and prevent shaking during baking. At the same time, the foot pads can prevent slipping and reduce vibration, and reduce noise.
[0024] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 5 The protective cover 2 is fixedly mounted on the carrier plate 1 with its opening facing forward. The carrier plate 1 has a slot within which a pull-out box 3 slides. The upper wall of the carrier plate 1 is a mesh panel. A transparent protective plate 9 is provided at the upper front end of the protective cover 2, facilitating operator observation of the internal PCB baking process and reducing the outward diffusion of exhaust gases and the splashing of waste materials from the PCB. The front side wall of the protective cover 2 is a sloped surface with its lower end tilted backward, facilitating operator handling of the PCB. An illumination tube 10 is provided on the upper inner wall of the protective cover 2, providing illumination in low-light conditions, allowing operators to more clearly observe the PCB baking status and make timely adjustments.
[0025] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 3 The striking structure includes a reversible motor 4, a crank 5, and a striking head 6. The reversible motor 4 is fixed inside the protective cover 2, the crank 5 is fixed at the output end of the reversible motor 4, and the striking head 6 is fixed at the extended end of the crank 5. The striking head 6 is made of spherical rubber material, which can reduce damage to the PCB board when striking, and at the same time use the elasticity of the rubber to generate appropriate striking force to effectively remove any debris that may remain on the board.
[0026] Combined with appendix Figure 2 Appendix Figure 3 Appendix Figure 4 The exhaust pipe 7 is fixedly installed above the protective cover 2, with its lower end extending into the inside of the protective cover 2 and facing the baking rack. The lower end of the exhaust pipe 7 is integrally formed with a trumpet-shaped exhaust head 11, which expands the exhaust range and can more efficiently extract the waste gas inside the protective cover 2, thereby enhancing the waste gas treatment effect.
[0027] The specific implementation of this utility model is as follows: The device is connected to an external power source, and the extraction pipe 7 is connected to an external extraction device. The PCB board is placed on the mesh plate of the carrier board 1. The four corner supports 8 of the carrier board 1 are stably supported by foot pads to prevent shaking. The operator bakes the PCB board. During the process, the internal situation can be observed through the transparent protective plate 9 at the upper front of the protective cover 2. The sloping design of the front side wall of the protective cover 2 facilitates the operation of the PCB board. After the device is turned on, the lighting tube 10 on the upper inner wall of the protective cover 2 provides illumination for clear observation of the baking status. At the same time, the forward and reverse motor 4 drives the crank 5 to rotate, so that the spherical rubber striking head 6 elastically taps the surface of the PCB board to remove debris. The exhaust gas generated during the baking process is extracted by the trumpet-shaped extraction head 11 at the lower end of the extraction pipe 7 and discharged to the subsequent processing system through the extraction pipe 7. During baking, the solder at the joint between the component and the board may fall off. The striking action of the striking head 6 can be used to assist in the disassembly of electronic components. The waste material falls into the pull-out box 3 through the mesh plate on the upper wall of the carrier board 1. Throughout the process, the protective cover 2 and the transparent protective plate 9 form a semi-enclosed space, reducing the leakage of exhaust gas and the splashing of waste materials, ensuring the safety and health of operators. The pull-out box 3 can be pulled out periodically for cleaning.
