Technical Field

[0001] The utility model belongs to the technical field of circuit board processing, in particular to a liquid medicine recovery device used for circuit board processing. Background Art

[0002] During the production process of circuit boards, chemical liquids are needed to treat the surface. The liquid can fill the holes of the circuit board, making the surface of the circuit board smoother, thereby improving the conductivity of the circuit board. The liquid can also form an anti-corrosion coating on the surface of the circuit board, thereby preventing the surface of the circuit board from being corroded and extending the service life of the circuit board. In order to save costs and protect the environment, the remaining liquid will be recycled after the processing is completed for easy reuse.

[0003] In the Chinese utility model patent with publication number CN216092451U, a device for collecting residual chemical liquid for circuit board production is proposed. The device solves the problem that too much residue in the residual chemical liquid often accumulates on the filter net and blocks the mesh on the filter net, resulting in the inability of personnel to effectively collect the residual chemical liquid and inconvenience in cleaning the residue on the filter net. However, in actual application, since the liquid used in circuit board processing has a certain viscosity, when the liquid is recovered by automatically flowing down and filtering, the flow rate of the liquid and the speed of passing through the filter hole are slow, which will affect the recovery speed of the liquid and the overall operating efficiency of the device.

[0004] Therefore, there is an urgent need to improve the existing chemical solution residual liquid collection device for circuit board production, and to provide a chemical solution recovery device for circuit board processing with a fast chemical solution recovery speed. Utility Model Content

[0005] The purpose of the utility model is to provide a circuit board processing liquid medicine recovery device with reasonable design, simple structure, fast liquid medicine recovery speed and high device operation efficiency in view of the deficiencies in the prior art, so as to solve the problems existing in the prior art.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A liquid medicine recovery device for circuit board processing comprises a recovery tank, wherein the outer wall at the front of the bottom of the recovery tank is inlaid with a discharge pipe, a slag discharge pipe is fixedly connected to the center of the bottom circle of the recovery tank, electric telescopic rods are fixedly installed on the outer walls on both sides of the bottom of the recovery tank, a slag discharge control component for opening and closing the slag discharge pipe is provided below the electric telescopic rod, a filter component is installed at the center of the top of the recovery tank, a conical gear ring is provided on the outer side of the top of the filter component, a drive motor is fixedly installed on the upper right side of the recovery tank, and a conical gear is fixedly connected to the output end of the drive motor, and the conical gear is meshed with the conical gear ring.

[0008] Preferably, the inner bottom of the recovery tank has an inclined structure.

[0009] Preferably, the slag discharge control assembly includes a cross bar, a vertical bar, a sealing block, a rubber rod and a first steel ball. The left and right ends of the cross bar are respectively fixedly connected to the telescopic ends of the two electric telescopic rods. The middle upper part of the cross bar is fixedly connected to a vertical bar, the top of the vertical bar is fixed with a sealing block, the top outer wall of the sealing block is symmetrically bonded with rubber rods, and the end of the rubber rod away from the sealing block is fixedly connected to the first steel ball.

[0010] Preferably, the center lines of the vertical rod, the sealing block and the slag discharge pipe coincide with each other, and the sealing block is arranged in a conical structure.

[0011] Preferably, the filter assembly includes a filter cartridge, an anti-backflow ring and a second steel ball. The top bearing of the filter cartridge is connected to the top center of the recovery tank. The anti-backflow ring is fixedly connected to the top inner wall of the filter cartridge. A plurality of the second steel balls are inlaid in a ring shape on the bottom inner wall of the filter cartridge.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] In the scheme of the utility model, by starting the driving motor to control the rapid rotation of the conical teeth, the conical gear ring can be controlled to drive the filter cartridge whose bearing is installed on the top of the recovery tank to rotate synchronously and rapidly. At this time, when the medicine is added to the filter cartridge, the centrifugal force generated by the rapid rotation of the filter cartridge can be used to "throw out" the medicine, effectively improving the filtration speed of the medicine, and utilizing the inclined inner bottom of the recovery tank to conveniently guide the filtered medicine to the discharge pipe for discharge and collection, which can shorten the time required for medicine recovery and improve the operating efficiency of the device.

[0016] After the filtration of the medicinal solution is completed, the utility model can control the entire slag discharge control component to rise slightly upward by contracting the electric telescopic rod, so that the first steel ball and the second steel ball are on the same horizontal plane, and the sealing block and the filter cartridge are out of contact and a larger gap is generated. At this time, the impurities filtered out of the filter cartridge can pass through the gap between the sealing block and the filter cartridge and be discharged through the slag discharge pipe. At the same time, the rapidly rotating filter cartridge facilitates continuous collision between the first steel ball and the second steel ball, which can cause the filter cartridge to vibrate slightly, which is conducive to the rapid discharge of impurities therein. The device has a simple structure, convenient operation and convenient slag discharge. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In this embodiment, the inclined inner bottom of the recovery tank 1 is utilized to facilitate guiding the filtered liquid medicine to the discharge pipe 2 for discharge and collection.

[0029] As a preferred embodiment, on the basis of the above structure, further, the slag discharge control component 4 includes a horizontal bar 41, a vertical bar 42, a sealing block 43, a rubber rod 44 and a first steel ball 45. The left and right ends of the horizontal bar 41 are respectively fixedly connected to the telescopic ends of the two electric telescopic rods 3, the vertical bar 42 is fixedly connected to the upper middle part of the horizontal bar 41, the sealing block 43 is fixed to the top of the vertical bar 42, the rubber rod 44 is symmetrically bonded to the top outer wall of the sealing block 43, and the first steel ball 45 is fixedly connected to the end of the rubber rod 44 away from the sealing block 43.

[0030] As a preferred embodiment, on the basis of the above structure, further, the center lines of the vertical rod 42, the sealing block 43 and the slag discharge pipe 5 coincide with each other, and the sealing block 43 is arranged in a conical structure.

[0031] In this embodiment, the sealing block 43 is provided to facilitate the sealing of the bottom opening of the filter assembly 6 to prevent the liquid medicine from entering the slag discharge pipe 5 and causing leakage.

[0032] As a preferred embodiment, on the basis of the above structure, the filter assembly 6 further includes a filter cartridge 61, an anti-return ring 62 and a second steel ball 63, the top bearing of the filter cartridge 61 is connected to the top center of the recovery tank 1, the anti-return ring 62 is fixedly connected to the top inner wall of the filter cartridge 61, and a plurality of second steel balls 63 are inlaid in a ring shape on the bottom inner wall of the filter cartridge 61.
