Description

Technical Field

[0002] Printed circuit boards are the core of all electronic devices. With the upgrading of electronic devices, more and more waste circuit boards are produced. The substrate of the circuit board is mainly composed of resin, glass fiber and copper foil. A large number of electronic components are fixed on the substrate. The pins of the electronic components are usually iron. After the electronic components are removed, the pins are easy to adhere to the solder. The copper foil is bonded to the substrate by epoxy resin adhesive. In order to better realize the recovery of metal copper, they need to be peeled off, that is, the epoxy coating in the printed circuit board is cleaned. When recycling the solder on the circuit board, the solder on the circuit board is generally heated manually to separate the solder to recycle the circuit board. This separation method is not only difficult but also inefficient. The Chinese patent announcement number is: CN110935713B discloses "A kind of waste circuit board recycling equipment". In this patent, by setting a positioning adjustment component, the direction of the air outlet can be adjusted according to different batches of circuit boards. The structure is simple and easy to operate. It can effectively make the wind blow evenly on the circuit board with a larger area. By setting an arc edge, the card block is easy to be stuck in the card slot, which is convenient for the staff to limit the ventilation pipe.

When the solder on the surface of the circuit board is detached, the impact assembly drives the circuit board to rotate close to the second plate body. The plane of the inclined shell is inclined to the ground and is located below the surface of the guide assembly.

[0022] The present invention provides a waste circuit board crushing and recycling device, which has the following beneficial effects:

[0023] 1. The waste circuit board crushing and recycling equipment has a guide component that slides and guides the impact component. When the impact component moves close to the storage box, the impact component drives the waste circuit board to rotate downward quickly, so that the waste circuit board generates a downward impact force. The tin material impacts downward tangentially to the surface of the guide component, and the double-sided solder is impacted through the opening to the inside of the storage box, so that the solder is cleaned and can be collected and utilized, solving the problem that the solder on the surface of the waste circuit board is difficult to clean and recycle.

[0024] 2. The waste circuit board crushing and recycling equipment, the heated solder passes through the opening to the inside of the storage box, and then the impact component drives the circuit board to move in the opposite direction to the copper foil recovery mechanism to separate and remove the copper foil. The circuit board is driven to the position directly above the crushing structure and falls vertically. The crushing roller structure of the crushing structure allows the non-metallic substrate to be crushed and recycled, so that the separation effect of solder, copper foil and non-metallic substrate is better.

[0025] 3. Compared with the shaking method, the waste circuit board crushing and recycling equipment uses impact force to clean the solder on the surface of the circuit board more cleanly. The recovery hole is used to recover the copper foil on the surface of the circuit board, and the board outlet hole is used to recover the non-metallic substrate. Driven by the support, the circuit board moves in a circle to different positions of the shell to complete the separation and recovery of the metal and non-metal of the circuit board, making the structure of the recycling device simpler and more reliable.

[0026] 4. In the waste circuit board crushing and recycling equipment, epoxy resin decomposition liquid is introduced into the inside of the water pipe, and the nozzle sprays the decomposition liquid onto the surface of the circuit board, the epoxy resin is decomposed, and the copper foil is separated from the circuit board. The reciprocating push of the scraping component enables the copper foil to be scraped off quickly, and the inclined setting of the inclined shell enables the cleaning liquid and the copper foil to be discharged through the bottom opening of the inclined shell, which solves the problem of poor separation effect of copper foil and non-metal after sorting the materials after crushing the circuit board.

[0027] 5. In the waste circuit board crushing and recycling equipment, when the inclined shell is driven through the circuit board, the frame is on the side of the circuit board surface close to the copper foil. When the epoxy resin is washed and decomposed, the electric cylinder drives the frame to move downward, and the scraper scrapes the copper foil away from the surface of the circuit board. The obstruction of the folding plate effectively avoids the splashing of the washing liquid. The solder and copper foil on the surface of the circuit board are widely distributed. In this device, the edge of the circuit board is clamped quickly and stably, which can effectively prevent the circuit board from being detached due to impact during detinning, and prevent the copper foil from being disturbed when being removed.

[0046] When in use, both sides of the waste circuit board are coated with solder, while one side is bonded with copper foil by epoxy resin. The middle position of the surface of the guide component 51 is engaged with the top of the storage box 43, and the waste circuit board is vertically placed into the top of the guide component 51. The impact component 54 clamps the position of the surface of the waste circuit board near the edge, and the oppositely arranged fixed table 52 supports the electric turntable 53, and the electric turntable 53 drives the impact component 54 to rotate, and the impact component 54 is driven to the top of the storage box 43. The guide component 51 guides the impact component 54 for sliding. When the impact component 54 moves close to the storage box 43, the impact component 54 drives the waste circuit board to rotate downward quickly, so that the waste circuit board generates a downward impact force, and the tin material impacts downward tangentially to the surface of the guide component 51, and the double-sided solder is impacted through the opening to the inside of the storage box 43, so that the solder is cleaned and can be collected and utilized, solving the problem that the solder on the surface of the waste circuit board is difficult to clean and difficult to recycle.

[0047] Second embodiment: Figure 3 As shown, the slide cylinder 41 is slidably mounted on the surface of the bracket 3, a bending rod 42 is fixedly connected to the surface of the slide cylinder 41, a storage box 43 is fixedly connected to the top of the bending rod 42, a fixed platform 52 is fixedly connected to the surface of the guide assembly 51, an electric turntable 53 is fixedly connected to the middle position of the fixed platform 52, and an impact assembly 54 is fixedly connected to the output end of the electric turntable 53;

[0048] The heating assembly 6 includes a first plate body 61, which is fixedly installed on the top of the guide assembly 51. The surface of the first plate body 61 is fixedly connected to a first guide rail 62, and the output end of the first guide rail 62 is fixedly connected to a sliding shell 63. The heating assembly 6 also includes a hydraulic cylinder 64, which is fixedly installed in the middle position of the surface of the sliding shell 63, and the output end of the hydraulic cylinder 64 is fixedly connected to a heating plate 65.

[0049] When in use, the upper position of the inner side surface of the impact component 54 limits the surface of the circuit board, and the sliding shell 63 moves downward under the drive of the first guide rail 62. When the heating plate 65 is opposite to the surface of the circuit board, the hydraulic cylinder 64 drives the heating plate 65 close to the circuit board. Since the solder protrudes from the non-metallic substrate, the heating plate 65 heats the solder. Then the sliding shell 63 is reset, and the impact component 54 drives the heated non-metallic substrate to move downward. During this process, the guide component 51 can slow down the decrease in the solder temperature. The impact component 54 drives the circuit board to quickly impact the middle position of the surface of the guide component 51, and the heated solder passes through the opening to the inside of the storage box 43. Then the impact component 54 drives the circuit board to move in the opposite direction to the copper foil recovery mechanism 7 to separate and remove the copper foil. The circuit board is driven to the position directly above the crushing structure 2 and falls vertically. The crushing roller structure of the crushing structure 2 allows the non-metallic substrate to be crushed and recovered, so that the separation effect of solder, copper foil and non-metallic substrate is better.

[0050] The third embodiment: Figure 3-Figure 6 As shown, the guide assembly 51 includes a shell 511, which is fixedly mounted on the top of the bracket 3.

[0051] The impact assembly 54 includes a support platform 541, which is fixedly installed on the output end of the electric turntable 53. An arc plate 542 is fixedly connected to the upper position of the surface of the support platform 541, and an arc cylinder 543 is fixedly connected to the middle position of the surface of the support platform 541.

The surface of the guide box 544 is fixedly connected to a gate hoist 545, and the side of the guide box 544 away from the gate hoist 545 is rotatably connected to an internal threaded ring 546.

[0052] When in use, the surface of the shell 511 is set to a truncated circular surface, and the truncated position enables the sliding cylinder 41 to drive the storage box 43 to move up and down. When the storage box 43 moves upward and engages with the support plate 514, the circuit board vertically passes through the board entry hole 513 to the inside of the guide box 544, and the support platform 541 rotates along the through hole 512 with the electric turntable 53 to approach the storage box 43.

The impact is directed to the surface of the support plate 514, and the cutting structure of the shell 511 enables the solder to quickly impact to the interior of the storage box 43 under the premise of heating. Compared with the shaking method, the solder on the surface of the circuit board can be cleaned more cleanly through the impact force. The recovery hole 515 is used for the recovery of the copper foil on the surface of the circuit board, and the board outlet hole 516 is used for the recovery of the non-metallic substrate.

[0055] When in use, the waste circuit board passes through the heating plate 65 and is vertically placed into the interior of the guide assembly 51, and then the impact assembly 54 drives the circuit board to rotate. When the solder on the surface of the circuit board is detached, the impact assembly 54 drives the circuit board to rotate close to the second plate body 71, and the plane of the inclined shell 73 is inclined to the ground and is located below the surface of the guide assembly 51. The second guide rail 72 drives the inclined shell 73 to move to the interior of the guide assembly 51, and the nozzle 75 and the water pipe 74 pass through the circuit board. The output end of the nozzle 75 is close to the epoxy resin on the surface of the circuit board, and the epoxy resin decomposition liquid is introduced into the interior of the water pipe 74. The nozzle 75 sprays the decomposition liquid onto the surface of the circuit board, the epoxy resin is decomposed, and the copper foil is separated from the circuit board. The reciprocating push of the scraping assembly 76 enables the copper foil to be quickly scraped off, and the inclined setting of the inclined shell 73 enables the cleaning liquid and the copper foil to be discharged through the bottom opening of the inclined shell 73, which solves the problem of poor separation effect of copper foil and non-metal after the circuit board is crushed.

[0056] Fifth embodiment: Figure 5 , Figure 6 , Figure 8 , Fig. 9 As shown, the support 541 is fixedly mounted on the output end of the electric turntable 53, the upper position of the support 541 surface is fixedly connected with an arc plate 542, the middle position of the support 541 surface is fixedly connected with an arc cylinder 543, the impact assembly 54 also includes a guide box 544, the lower position of the guide box 544 surface is fixedly mounted on the output end of the arc cylinder 543, the surface of the guide box 544 is fixedly connected with a gate hoist 545, and the side of the guide box 544 away from the gate hoist 545 is rotatably connected with an internal thread ring 546;

The scraping assembly 76 also includes an intercepting bar 764, which is fixedly installed at a lower position on the inner side of the frame 763. The bottom of the inner side of the frame 763 is fixedly connected to a slotted plate 765, and the bottom of the slotted plate 765 is fixedly connected to a scraper 766.

[0058] When in use, the waste circuit board is vertically placed into the inside of the guide box 544. A small hole is opened on the surface of the circuit board near the edge, and the opening and closing machine 545 is opposite to the small hole. The opening and closing machine 545 drives the screw to be screwed into the inside of the guide box 544 and pass through the circuit board. Then, the screw is screwed into the inside of the internal thread ring 546, so that the internal thread ring 546 approaches and squeezes the guide box 544. The elasticity of the guide box clamps the circuit board, so that the circuit board is not easy to deflect and shake when moving. When the tilting shell 73 is driven to pass through the circuit board, the frame 763 is on the side of the circuit board surface close to the copper foil. When the epoxy resin is washed and decomposed, the electric cylinder 762 drives the frame 763 to move downward, and the scraper 766 scrapes the copper foil and separates it from the surface of the circuit board. The obstruction of the folding plate 761 effectively avoids the splashing of the washing liquid. The solder and copper foil on the surface of the circuit board are widely distributed. In this device, the edge of the circuit board is clamped quickly and stably, which can effectively prevent the circuit board from being impacted and detached during detinning, and prevent the copper foil from being disturbed when being removed.
