DETAILED DESCRIPTION

[0027] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0028] Embodiment: A circuit board recycling device, see Figure 1 and Figure 2 As shown, it includes a cylinder 1, a mounting frame 101, a connecting column 102, a flip plate 103, a driving member 104, a material discharge baffle 105, a collecting frame 106 and a screening component 2. A non-enclosed cylinder 1 is installed on the mounting frame 101. The left side of the cylinder 1 is opened. A material discharge baffle 105 is slidably arranged on the outer wall of the left side of the cylinder 1. An n-shaped handle 1051 is arranged on the outer wall of the material discharge baffle 105. A connecting column 102 is rotatably installed in the cylinder 1. A plurality of flip plates 103 are fixedly installed on the outer circular wall of the connecting column 102. A heating member for melting the solder points on the circuit board is arranged on the flip plate 103. The connecting column 102 passes through the cylinder 1 and is connected to the output shaft of the driving member 104 arranged on the outer wall of the cylinder 1. The driving member 104 drives the connecting column 102 to rotate clockwise. The driving member 104 is a motor setting, and a collection frame 106 for collecting circuit boards is set at the bottom of the cylinder 1. There are two collection frames 106, one of which is used to collect screened electronic components, and the other is used to collect circuit board bodies. A screening component 2 for screening circuit boards is provided above the collection frame 106 on the left. The screening component 2 includes an n-type frame 201 set on the mounting frame 101 and a screening frame 202 slidably mounted on the n-type frame 201. A screening net is set in the screening frame 202, and the right side of the screening frame 202 is an opening setting. The screening frame 202 is set directly below one side of the opening of the cylinder 1. The screen in the screening frame 202 is inclined, and its height gradually decreases from left to right. The mounting frame 101 is also provided with a shaking mechanism 3 for making the screening frame 202 reciprocate.

[0029] See also Figure 3As shown, the shaking mechanism 3 includes a vertical plate 301, a cam 302, a transmission assembly 303 and a first return spring 304. The mounting frame 101 is provided with a vertical plate 301, and the cam 302 is rotatably mounted on the vertical plate 301. The center line of the shaft connected to the cam 302 is perpendicularly intersected with the center line of the rod-shaped member on the upper part of the n-type frame 201. A transmission assembly 303 is arranged between the shaft connected to the cam 302 and the connecting column 102. The transmission assembly 303 includes a pulley installed on the connecting column 102, a pulley coaxially connected to the cam 302, and a transmission belt between the two pulleys. The driving member 104 drives the cam 302 to rotate through the transmission assembly 303. The rotation of the cam 302 repeatedly squeezes the connection between the screening frame 202 and the n-type frame 201, and the screening frame 202 slides left and right along the rod-shaped member on the n-type frame 201. A first return spring 304 is wound around the n-type frame 201, and the two ends of the first return spring 304 are respectively connected to the n-type frame 201 and the screening frame 202.

[0030] See also Figure 4 and Figure 7 As shown, a blocking component 4 for blocking the circuit board on the screening net in the screening frame 202 is provided on the side of the screening frame 202 tilted downward, and the blocking component 4 includes a blocking plate 401, an L-shaped rotating rod 402 and a torsion spring 403. The blocking plate 401 is rotatably installed between the two inner walls on the right side of the screening frame 202. The left side of the blocking plate 401 is an inclined surface tilted upward, and the thickness of the blocking plate 401 gradually increases from top to bottom. The end of the blocking plate 401 that rotates through the screening frame 202 is fixedly connected with the L-shaped rotating rod 402, and the L-shaped rotating rod 402 is wound with a torsion spring 403, and the two ends of the torsion spring 403 are respectively connected to the L-shaped rotating rod 402 and the outer wall of the screening frame 202.

[0031] See also Figure 5 and Figure 6 As shown, it also includes a pushing component 5 for pushing the circuit board in the screening frame 202 into the collecting frame 106, and the pushing component 5 includes a sliding rod 501, a pushing plate 502, a pushing handle 503 and a compression spring 504. Two sliding rods 501 are slidably installed on the left side of the screening frame 202, and the two ends of the sliding rod 501 are respectively connected to the pushing plate 502 and the pushing handle 503, wherein the pushing plate 502 is arranged in the screening frame 202, and a compression spring 504 is wound around the sliding rod 501, and the two ends of the compression spring 504 are respectively connected to the outer wall of the screening frame 202 and the pushing handle 503.

[0032] See also Figure 6 and Figure 7As shown, it also includes a pushing assembly 6 for pushing the L-shaped rotating rod 402 to rotate to release the blocking effect of the blocking plate 401. The pushing assembly 6 includes a connecting plate 601, an L-shaped push plate 602 and a pushing rod 603. The two ends of the push plate 502 are connected to the connecting plates 601, and the L-shaped push plate 602 is slidably installed on the connecting plate 601. The L-shaped push plate 602 is provided with a push rod 603, which is driven by the push plate 502 to move toward the push rod 603 and squeeze the push rod 603. The push rod 603 is forced to rotate. Since the L-shaped push plate 602 is slidably installed on the connecting plate 601, when the L-shaped push plate 602 squeezes the push rod 603, when the resistance of the push rod 603 is greater than the thrust of the L-shaped push plate 602, the L-shaped push plate 602 moves upward along the connecting plate 601 and continues to squeeze and push the push rod 603 until the push rod 603 is pushed and rotated. Under the action of gravity, the L-shaped push plate 602 moves downward along the connecting plate 601, thereby ensuring that the blocking plate 401 is driven by the push rod 603 to rotate 90 degrees clockwise, thereby releasing the blocking function of the blocking plate 401.

[0033] See also Figure 1-9 As shown, the outer wall of the cylinder 1 is provided with limit assemblies 7 on both sides, with the opening of the cylinder 1 as the center, for limiting the unloading baffle 105. The limit assembly 7 includes a mounting bracket 701 mounted on the outer wall of the cylinder 1, an n-shaped rod 702 slidably mounted on the mounting bracket 701, a wedge block 703 mounted on the end of the n-shaped rod 702, and a second return spring 704 wound around the n-shaped rod 702, and the inclined surfaces of the two wedge blocks 703 are arranged opposite to each other.

[0034] When the device is used to disassemble and recycle the circuit board, the circuit board to be disassembled is placed in the cylinder 1 through the opening on the left side of the cylinder 1, the circuit board is heated by the heater on the flip plate 103, and the connecting column 102 and the flip plate 103 are driven to rotate by the driving member 104, thereby melting the solder points on the circuit board, achieving the effect of separating and disassembling the circuit board and the electronic components, and then by pulling the unloading baffle plate 105 upwards, the disassembled and separated circuit board and electronic components fall into the screening frame 202; at this time, the driving member 1 04 drives the cam 302 to rotate through the transmission assembly 303. When the cam 302 rotates, the contour shape of the cam 302 exerts a force on the connection between the screening frame 202 and the n-type frame 201, so that the screening frame 202 moves linearly along the upper transverse rod-shaped member of the n-type frame 201. The first reset spring 304 provides a reset power for the reset of the screening frame 202, thereby causing the screening frame 202 to reciprocate linearly on the n-type frame 201. When the cam 302 no longer exerts a force on the screening frame 202, the first reset spring 304 is in the state of being reset. Under the action of the elastic force of the spring 304, the screening frame 202 is reset sharply, and this is repeated to achieve the shaking of the screening frame 202, so that the electronic components pass through the filter screen of the screening frame 202 and fall into the collection frame 106 below the screening frame 202, and the circuit board is blocked on the filter screen of the screening frame 202; at this time, the push plate 502 is pushed from left to right by pushing the handle 503. When the push plate 502 is pushed to the right, the circuit board on the filter screen in the screening frame 202 is pushed toward the collection frame 106 on the right. At the same time, the L-shaped push plate 503 is pushed from left to right. The plate 602 gradually approaches the push rod 603 and generates an extrusion force on the push rod 603. Under the thrust of the L-shaped push plate 602, the push rod 603 drives the L-shaped rotating rod 402 to rotate clockwise around the connection between the blocking plate 401 and the screening frame 202, thereby releasing the blocking effect of the blocking plate 401 on the circuit board. At this time, both the torsion spring 403 and the compression spring 504 are deformed. When no force is applied to the push handle 503, the torsion spring 403 and the compression spring 504 are reset, and the baffle is reset.

[0035] The above-mentioned embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person skilled in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
