It has excellent insulation performance, high temperature resistance, corrosion resistance and mechanical strength, so it is widely used in aerospace, military, communication, automobile, computer and other fields. Ceramic circuit board is actually made of electronic ceramic materials and can be made into various shapes. It has the most outstanding characteristics of high temperature resistance and high electrical insulation performance, including low dielectric constant, low dielectric loss, high thermal conductivity, good chemical stability and similar thermal expansion coefficient of components.

[0003] Ceramic printed circuit boards are produced using laser rapid activation metallization technology and are used in the LED field, high-power semiconductor modules, semiconductor coolers, electronic heaters, power control circuits, power hybrid circuits, intelligent power components, high-frequency switching power supplies, solid-state relays, automotive electronics, communications, aerospace and military electronic components.

[0022] Working principle: When recycling ceramic waste circuit boards, first the surface cleaning mechanism is started, and the staff sends the ceramic waste circuit boards to be processed into the processing box one through the sliding track in the middle of the guide seat in turn. The ceramic circuit boards entering the processing box one fall into the bottom limit seat on the conveyor belt, and the bottom of the ceramic circuit board is clamped and fixed by the bottom limit seat on the conveyor belt. Then, as the conveyor belt is continuously conveyed, the top of the ceramic circuit board fixed by the bottom limit seat on the conveyor belt enters the top auxiliary seat, thereby completing the fixation and conveying of the ceramic circuit board. Then, the driving motor one on the processing box one is started, and the rotating shaft of the driving motor one drives the top auxiliary seat in the processing box one to rotate synchronously while rotating. The top auxiliary seat drives the installation connecting belt on the same side to rotate synchronously while rotating. The installation connecting belt drives the cleaning fiber strips on it to move synchronously while rotating. The cleaning fiber strips clean the dust and impurities attached to the surfaces of both sides of the waste ceramic circuit boards transported and moved by the conveyor belt while moving, thereby completing the surface cleaning of the ceramic waste circuit boards. Treatment; at the same time, the adsorption purification mechanism is started, first the fan on the installation box is started, the fan exhausts air into the installation box through the connecting pipe, and the installation box simultaneously exhausts air to the drainage hood on the rear side of the treatment box through the connecting pipe, so that the drainage hood becomes a negative pressure state, and then the dust and impurities generated by the operation of the surface cleaning mechanism in the treatment box enter the drainage hood, and then the dust and impurities entering the drainage hood enter the installation box through the connecting pipe, and the air entering the installation box carries dust and impurities from the cleaning treatment, first the dust and impurities contained in the air are filtered through the filter cotton plate on one side of the installation frame, and then the air after the filtration treatment is burned again by the flamethrower in the installation box, and finally the air after the combustion treatment is purified and adsorbed multiple times by the activated carbon plate on the other side of the installation frame, so that the harmful substances contained in the air are completely removed, and finally the air after multiple treatments is discharged into the external environment by the pumping of the fan, so as to complete the adsorption and purification of the dust and harmful substances generated in the cleaning process;After that, the attachment separation mechanism is started, and as the conveyor belt in the processing box 1 continuously conveys the ceramic waste circuit board, when it conveys the ceramic waste circuit board to the position of the sliding seat, the hydraulic cylinder on the processing box 1 is started, and the rod body of the hydraulic cylinder is pushed out, and the hydraulic cylinder rod body drives the scraping seat in the sliding seat to move down synchronously while pushing out, and the sliding seat scrapes and separates the metal layer on the ceramic waste circuit board in the conveyor belt and the electronic components attached to the surface of the metal layer while moving down synchronously, after scraping the metal layer and the electronic components attached to the ceramic waste circuit board, it is conveyed to the diverter seat with the conveyor belt in the processing box 1, and its materials are diverted by the inclined diverter plate in the diverter seat, the ceramic substrate material enters one side of the diverter seat for temporary storage, and the scraped and separated metal material enters the other side of the diverter seat for temporary storage, thereby completing the attachment separation process of the ceramic waste circuit board;After that, the integrated processing mechanism is started, and the article elevator transports the ceramic substrate material in the diverter seat into the connection box. Then, the ceramic substrate material entering the connection box falls into the crushing chamber 1 in the processing box 2. At this time, the driving motor 2 on the processing box 2 is started, and the rotating shaft of the driving motor 2 drives the extrusion crushing roller on one side of the crushing chamber 1 to rotate while rotating. The extrusion crushing roller drives the extrusion crushing roller on the other side to rotate through the synchronous gear plate while rotating. The rotation of the two extrusion crushing rollers cooperates with the inner wall of the crushing chamber 1, thereby crushing the ceramic substrate material entering the crushing chamber 1. The material is initially crushed, and then the ceramic material that has been crushed in the crushing chamber one falls into the crushing chamber two. At this time, the driving motor three on the processing box two is started, and the rotating shaft of the driving motor three drives the driving shaft in the crushing chamber two to rotate through the closing cover while starting. The driving shaft drives the rotating seat at the bottom of the triangular rod to rotate while the rotating seat drives the breaking rod thereon to rotate. Through the cooperation of the breaking rod on the rotating seat and the inclined plate in the crushing chamber two, the ceramic material that has been initially crushed is crushed again, and then passes through the crushing chamber two. The ceramic material after the second crushing process falls into the grinding chamber, and the driving shaft drives the grinding seat on it to rotate synchronously while rotating, so that the ceramic material entering the grinding chamber is ground and crushed. At the same time, the grinding chamber rotates and drives the connecting rod inside it to rotate synchronously. The connecting rod drives the upper convex seat at the bottom to rotate synchronously while rotating. The upper convex seat drives the lower convex seat at the bottom to move up and down in a circular motion while rotating. The lower convex seat drives the breaking rod at the bottom to slide on the sliding rod while moving up and down in a circular motion, and at the same time, the connecting spring on the sliding rod is used to connect the connecting rod. Support it to reset, and at the same time, when the conduction seat moves up and down, it also impacts and vibrates the annular screen at the bottom, so that the ceramic material after grinding is vibrated and screened. After the screening process, the ceramic material falls down, and the airflow metal separator on the processing box 2 is started, so as to sort the ceramic material in the falling process, and collect the sorted materials through the metal impurity cavity and ceramic base cavity at the bottom of the processing box 2. After a certain amount of them are collected, the staff collects them through the cleaning door 1 on the processing box 2. ;

[0023] The present invention provides a recycling and processing device for waste circuit boards. It has the following beneficial effects:

[0024] 1. The present invention adds and sets a surface cleaning mechanism to clean the dust and impurities on the surface of the waste ceramic circuit board when processing it. On the one hand, it can effectively remove the dust and impurities on the surface of the waste ceramic circuit board. After the cleaning, the circuit board surface is cleaner, reducing the interference of impurities on material separation and reprocessing, improving the recycling efficiency and quality, and on the other hand, it can also reduce the environmental impact of the waste treatment process. The cleaned waste ceramic circuit board is safer to handle, reducing possible pollution sources and harmful substances released, meeting environmental protection requirements and regulatory standards, and the cleaned ceramic circuit board also helps to improve the appearance quality of the waste circuit board, making it more suitable for secondary use or processing.

[0025] 2. The present invention adds and sets an adsorption purification mechanism, which, when in use, can not only filter and adsorb the dust generated during the treatment process, thereby avoiding environmental pollution caused by subsequent direct emissions, but also prevent adverse effects on the surrounding air environment and staff by igniting the remaining flammable and harmful substances in the air and performing multiple adsorption and purification treatments.

[0026] 3. The present invention adds and sets an accessory separation mechanism. First, the metal layer on the ceramic waste circuit board and the electronic components thereon can be separated by the accessory separation mechanism, which helps to improve the recovery rate of valuable materials in the waste circuit boards. Through precise separation, these resources can be recovered more effectively, reducing resource waste and environmental impact. The accessory separation mechanism also helps to simplify the subsequent processing flow. After separating the metal layer and the electronic components, different material types can be specially treated and reprocessed, making the recycling process more efficient and economical. This precise separation also helps to reduce losses and impurities in the processing process, improves the quality and availability of reprocessed materials, and also helps to reduce the environmental negative impact of the waste circuit board processing process, thereby reducing the risk of secondary pollution and meeting environmental protection standards and sustainable development requirements.

[0027] 4. The present invention increases and sets an integrated processing mechanism, and one mechanism can successively complete multiple production processes such as primary crushing, secondary crushing, grinding and vibration screening. On the one hand, it can reduce the number of equipment inputs in the recycling process of ceramic substrate materials, thereby reducing the cost of ceramic substrate recycling. On the other hand, it can also reduce the circulation time of ceramic materials between different processes, which is convenient for continuous recycling processing and can also improve the processing efficiency of waste ceramic substrates. In addition, through a series of treatments on ceramic materials, it can also reduce the waste of ceramic materials and improve the resource utilization rate of ceramic materials.

[0028] 5. During the use of the equipment of the present invention, not only can the length of the overall waste ceramic circuit board recycling production line be reduced, the floor space occupied by various equipment can be saved, thereby improving the utilization rate of the enterprise's production site, but the mechanism is also simple to operate, which can reduce the enterprise's human cost investment in the process of recycling waste ceramic circuit boards, and can also improve the safety and stability of production, facilitating the normal recycling of waste ceramic circuit boards.

[0044] When the surface cleaning mechanism is started, the staff will send the ceramic waste circuit boards to be processed into the processing box 1 through the downward slide 21 in the middle of the guide seat 3 in turn. The ceramic circuit boards entering the processing box 1 fall into the bottom limit seat 22 on the conveyor belt 23, and the bottom of the ceramic circuit board is clamped and fixed by the bottom limit seat 22 on the conveyor belt 23. Then, as the conveyor belt 23 is continuously conveyed, the top of the ceramic circuit board fixed by the bottom limit seat 22 on the conveyor belt 23 enters into the top auxiliary seat 25, thereby completing the fixation and conveying of the ceramic circuit board.

[0045] The surface cleaning mechanism also includes two groups of mounting rollers 5. Two groups of mounting rollers 5 are equidistantly arranged on the front and rear sides of the top of the inner wall of the processing box 1. The mounting rollers 5 on the same side are connected by a mounting connecting belt 24. A cleaning fiber strip 26 is arranged on the outer wall of the mounting connecting belt 24. A driving motor 4 is arranged on both sides of the middle part of the top of the processing box 1, and the output end of the driving motor 4 passes through the processing box 1 and is connected to the middle part of the mounting roller 5 at the corresponding position.

[0049] When the adsorption purification mechanism is started, the fan 14 on the installation box 2 is started first, and the fan 14 draws air into the installation box 2 through the connecting pipe. The installation box 2 simultaneously draws air to the drainage hood 19 on the rear side of the processing box 1 through the connecting pipe, thereby making the drainage hood 19 a negative pressure state, and then the dust and impurities generated by the operation of the surface cleaning mechanism in the processing box 1 enter the drainage hood 19, and then the dust and impurities entering the drainage hood 19 enter the installation box 2 through the connecting pipe.

[0058] When the integrated processing mechanism is started, the article elevator 7 transports the ceramic substrate material in the diverter seat 13 into the connection box 8, and then the ceramic substrate material entering the connection box 8 falls into the crushing chamber 34 in the processing box 12. At this time, the driving motor 29 on the processing box 12 is started, and the rotating shaft of the driving motor 29 drives the extrusion crushing roller 35 on one side of the crushing chamber 34 to rotate while rotating. The extrusion crushing roller 35 drives the extrusion crushing roller 35 on the other side to rotate through the synchronous gear disc 15 while rotating.
