Description

Technical Field

[0001] This utility model relates to the field of circuit board manufacturing technology, and in particular to a dry film residue recycling and weight reduction device. Background Technology

[0002] In the circuit board manufacturing process, dry film is used in the exposure and development steps to accurately transfer the designed circuit pattern to the copper-clad laminate. After the etching process, the circuit board needs to undergo a stripping process. Stripping requires stripping chemicals, and the resulting dry film residue is a highly alkaline, mud-like substance that requires specialized recycling companies to prevent environmental pollution. The dry film residue contains a large amount of stripping chemicals; directly entrusting it to a recycling company would waste a significant amount of these chemicals and increase processing costs. Therefore, weight reduction processing of the stripped dry film residue is necessary. Currently, the stripped dry film residue is generally transported manually from the stripping unit to a residue recycling and weight reduction unit. This process is prone to causing the residue to fall off and may increase worker health risks. While conveyor belts can also be used to transport the residue from the stripping unit to the recycling and weight reduction unit, the mud-like residue is highly adhesive and easily sticks to the conveyor belt, affecting machine operation and potentially falling off and contaminating the production workshop. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art.

[0036] Reference Figs. 1 to 3This utility model provides a dry film sludge recycling and weight reduction device, including an extrusion mechanism 100, a feeding mechanism 200, a waste sludge collection mechanism 300, and a waste liquid collection mechanism 400. The extrusion mechanism 100 includes a first inlet 110, a first outlet 120, and a second outlet 130. The extrusion mechanism 100 is used for extruding and dewatering the dry film sludge. Specifically, the extrusion mechanism 100 is a screw extruder, including an extruder housing and an extrusion screw (not shown in the figure). The first inlet 110 is located at one end of the extruder housing, and the first outlet 120 is located at the other end of the extruder housing. The first feed port 120 is located at the other end of the extruder housing away from the first feed port 110, and the second discharge port 130 is located below the end of the extruder housing near the first feed port 110. Dry film residue enters the screw extruder from the first feed port 110. The extrusion screw extrudes the dry film residue from the first feed port 110 towards the first discharge port 120, separating the film removal solution. The extruded waste residue falls out from the first discharge port 120, and the extruded film removal solution flows through a pipe to the second discharge port 130 for discharge. The feeding mechanism 200 includes a cylinder 21. 0. The feeding screw 220 and the third discharge port 230 are rotatably connected with the cylinder 210 with a clearance fit. The third discharge port 230 is located at one end of the cylinder 210 and is connected to the first inlet port 110. Specifically, the feeding screw 220 includes a rod and screw blades, and the screw blades rotate around the rod and extend. Specifically, the feeding mechanism 200 also includes a second inlet port 240, which is located at the end of the cylinder 210 away from the third discharge port 230. The second inlet port 240 can be configured to... Below the dry film residue outlet of the film stripping device, the dry film residue enters the feeding mechanism 200 through the second inlet 240. The screw pushes the dry film residue from the second inlet 240 to the third outlet 230. Then, the dry film residue is fed from the third outlet 230 into the first inlet 110 and then into the screw extruder for extrusion. The waste residue collection mechanism 300 is connected to the first outlet 120 and is used to collect the waste residue after dewatering. The waste liquid collection mechanism 400 is connected to the second outlet 130 and is used to collect the extruded film stripping solution waste liquid.

[0037] The extrusion mechanism 100 squeezes out the desiccant from the dry film residue, reducing its weight and facilitating recycling, thus lowering recycling costs. The extruded desiccant can be reused, reducing waste of production resources and lowering production costs. The feeding screw 220 of the feeding mechanism 200 rotates with a gap inside the cylinder 210, pushing the mud-like dry film residue from the second inlet 240 to the third outlet 230. This method is highly automated, requires no worker contact, and reduces health risks. The cylinder 210 and feeding screw 220 of the feeding mechanism 200 work together, and even if the mud-like dry film residue adheres to the feeding screw 220, it does not affect the normal operation of the feeding mechanism 200. The dry film residue remains inside the cylinder 210 of the feeding mechanism 200, preventing it from falling out and ensuring high reliability.

[0038] Understandably, referring to Fig. 2 In some other embodiments, the width of the third discharge port 230 is similar to the distance that the screw blades of the feeding screw 220 extend axially after rotating 360 degrees, so as to improve the discharge efficiency of the third discharge port 230.

[0039] According to some embodiments of this application, the third discharge port 230 is sealed to the first inlet port 110 to prevent dry film residue from falling from the third discharge port 230 to the outside of the first inlet port 110.

[0040] Furthermore, the opening of the third discharge port 230 is set downwards so that the mud-like dry film residue can fall out of the third discharge port 230 more easily. Specifically, the opening of the first inlet port 110 is set upwards and matched with the third discharge port 230, so that the dry film residue falling out of the third discharge port 230 can fall directly into the first inlet port 110, thereby improving the discharge efficiency of the third discharge port 230.

[0041] Furthermore, a vibration mechanism 500 is connected to one side of the feeding mechanism 200 where the third discharge port 230 is located. When the dry film residue recycling and weight reduction device needs to be suspended for a long time, the vibration mechanism 500 is used to vibrate the cylinder 210 near the third discharge port 230. This vibration can cause the dry film residue adhering to the third discharge port 230 and the feeding screw 220 to fall off, thus preventing the dry film residue from being left inside the cylinder 210 of the feeding mechanism 200.

[0042] Furthermore, the third discharge port 230 is connected to the first inlet port 110 by a flexible pipe 600, which can prevent the vibration generated by the vibration mechanism 500 from being transmitted to the extrusion mechanism 100 through the feeding mechanism 200. The flexible pipe 600 acts as a buffer, which can effectively reduce the transmission of vibration.

[0043] According to some embodiments of this application, the waste liquid collection mechanism 400 includes a filter assembly 410 and a tank 420. The filter assembly 410 is connected between the second discharge port 130 and the tank 420. The filter assembly 410 is used to filter the desiccant waste liquid generated after squeezing the dry membrane residue, thereby reducing the flow of dry membrane residue particles into the tank 420 and improving the purity of the desiccant waste liquid, so as to better recycle and reuse the desiccant waste liquid.

[0044] Furthermore, referring to Fig. 3 The filter assembly 410 includes a funnel-shaped first guide 411 and a filter element 412. The filter element 412 is disposed inside the first guide 411, and the first guide 411 is connected between the second outlet 130 and the tank body 420. The filter element 412 filters dry membrane residue particles, and the funnel-shaped first guide 411 can centrally guide the membrane stripping solution waste liquid, preventing spillage. Furthermore, the opening of the tank body 420 only needs to match the outlet of the funnel-shaped first guide 411, reducing waste liquid evaporation.

[0045] Furthermore, the filter element 412 is detachably connected to the first guide 411. When the filter element 412 is severely clogged, it can be replaced directly, which is convenient and quick.

[0046] According to some embodiments of this application, the waste collection mechanism 300 includes a second guide 310 and a collection box 320. The second guide 310 is connected between the first discharge port 120 and the collection box 320. The second guide 310 guides the waste that falls after being squeezed to the collection box 320 to avoid polluting the environment.

[0047] Furthermore, the second guide 310 has a funnel-shaped structure to improve the waste slag guiding effect.

[0048] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention.
