Description

Technical Field

[0001] The invention relates to the technical field of circuit board film stripping, in particular to a circuit board film stripping device which is convenient for scraping and collecting waste liquid. Background Art

[0002] With the rapid development of the electronics industry, flexible circuit boards have been widely used in various electronic devices due to their excellent bending performance and light weight. In the manufacturing process of flexible circuit boards, film stripping is a crucial process, which involves removing excess film layers on the circuit board to prepare for subsequent circuit wiring or other process steps.

[0003] The existing patent announcement number CN222053480U is a film stripping device that is convenient for scraping and collecting waste liquid. When stripping the film on the circuit board, the circuit board enters the equipment horizontally during the process of spraying the liquid medicine. In this way, the waste on the circuit board is not easy to be scraped clean after spraying the liquid medicine, which will cause debris to remain on the circuit board, resulting in poor cleaning effect. In addition, when loading the circuit board, the clamp needs to be opened first, and then the two ends of the circuit board need to be clamped. This back and forth operation is time-consuming and labor-intensive, very inconvenient, and only one circuit board can be stripped at a time, which reduces the overall efficiency. At the same time, when filtering the liquid medicine after spraying, there is a lack of safety protection measures, and the liquid medicine is easy to splash everywhere when it falls, causing pollution or harm to the staff.

The operation of multiple first motors 202 facilitates the drive control of the conveyor belt 203, so that the circuit board can be well transported to the liquid medicine at the bottom of the water tank 1 for immersion and film removal.

[0041] Specifically, Figure 1 , Figure 2 and Figure 3 As shown, a protective cover 204 is installed on the top of the water tank 1, and the two ends of the protective cover 204 are trapezoidal structures. A control valve 205 is installed on the bottom of one side of the water tank 1. The installation of the protective cover 204 is beneficial to shielding and protecting the two ends of the top of the water tank 1. The connection between the control valve 205 and the external pipeline is beneficial to transport the medicine to the water tank 1, which is convenient for filling or exporting the medicine.

[0042] Specifically, Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the clamping mechanism 3 includes a fixed seat 302. A plurality of symmetrically and equidistantly distributed fixed seats 302 are installed on the conveyor belt 203. Sliders 303 are respectively installed at the opposite ends of two symmetrically distributed fixed seats 302. The sliders 303 are slidably connected to the inner side of the fixed seat 302 through compression springs 304. The tops of the two sliders 303 are respectively vertically connected with clamping plates 301. The two clamping plates 301 are in a "T" shape. The two clamping plates 301 are slidably connected to the fixed seat 302 through the sliders 303. Guide grooves 305 are provided on the opposite sides of the tops of the two clamping plates 301. Through the installation of a plurality of symmetric fixed seats 302, it is beneficial to install a plurality of symmetric clamping plates 301. Under the resistance of the compression springs 304, the two sliders 303 will drive the two clamping plates 301 to approach each other, so as to realize stable clamping of the circuit board. Through the opening of the guide grooves 305, it is beneficial for the circuit board to be inserted between the two clamping plates 301. Through the vertical clamping between the circuit board and the two clamping plates 301, the conveyor belt 203 conveys the circuit board into the water storage tank 1 for film removal. By placing the circuit board vertically, it is beneficial for the waste liquid to be well discharged and not easy to remain.

[0043] Specifically, such as Figure 3 , Figure 5 , Figure 6 and Figure 7As shown, the interference mechanism 4 includes a driving rod 403. Among the two symmetrical clamping plates 301, the driving rod 403 is vertically and slidably connected to the side wall of one of the clamping plates 301, and one end of the driving rod 403 is vertically and fixedly connected to the side wall of the other clamping plate 301.

The clamping plate 402 is snap-fitted with the mounting block 401 through the clamping groove 405. Through the installation of the driving rod 403, it is beneficial to drive and control one of the clamping plates 301. When the conveyor belt 203 moves to a certain position, the guide wheel 404 on the driving rod 403 abuts against the clamping plate 402, and the driving rod 403 is abutted to squeeze the clamping plate 301, so that the clamping plate 301 drives the slider 303 to slide out of the elastic force of the compression spring 304, realizing the separation of the two clamping plates 301, facilitating the loading or taking out of the circuit board. After the conveyor belt 203 moves to a certain position again, the driving rod 403 is separated from the clamping plate 402, and the clamping plate 301 resets.

A plurality of delivery pipes 502 are connected to both sides of the water storage tank 1. One end of each of the plurality of delivery pipes 502 extends to the inside of the water storage tank 1 respectively. Vertical plates 503 are installed at one end of each of the plurality of delivery pipes 502. Spray holes 504 are provided on one side of each of the plurality of vertical plates 503.

By installing the water pump 501, it is beneficial to extract the filtered liquid medicine inside the bottom of the water storage tank 1, and convey it to the inside of the plurality of delivery pipes 502 through the connecting pipes 505. The plurality of delivery pipes 502 enable the liquid medicine to be sprayed out through the spray holes 504 on one side of the vertical plates 503, which is beneficial to spray both sides of the circuit board conveyed on the conveyor belt 203, so that the circuit board can be better degummed.

[0045] Specifically, as Figure 2 , Figure 4 and Figure 9 shown, the scraping mechanism 6 includes a second motor 601. A plurality of second motors 601 evenly distributed at equal intervals are installed on both sides of the water storage tank 1 respectively. The output shafts of the plurality of second motors 601 extend to the inside of the water storage tank 1.

The scraping plate 602 is located at the bottom of the conveyor belt 203, which is beneficial to scrape the residual film on both sides of the circuit board after spraying, so that the degumming effect is better.

[0046] Specifically, as Figure 9As shown in the figure, one end of multiple groups of the rotating shafts 604 is rotatably connected to a control board 605.

The output shafts of the electric push rods 606 are slidably connected to the side wall of the water storage tank 1. Through the installation of the control board 605, it is beneficial to control the rotating shaft 604. Through the sliding connection between the output shaft of the second motor 601 and the inside of the rotating shaft 604, under the control of two electric push rods 606, the position of the control board 605 is controlled, and then the control board 605 drives the rotating shaft 604 to slide on the output shaft of the motor, thereby adjusting the position of the scraping plate 602 and the circuit board, facilitating the scraping of circuit boards with different thicknesses and preventing damage to the circuit board.

[0047] Specifically, as Figure 1 、 Figure 4 and Figure 10 shown, the filtering mechanism 7 includes a collection box 701. The collection box 701 is slidably connected to the inner bottom of the water storage tank 1. The collection box 701 has a funnel-shaped structure with an open bottom.

A sealing ring 704 is snap-connected to the outer side wall of one end of the collection box 701. The outer side wall of the sealing ring 704 abuts against the inner side wall of the water storage tank 1. Two handles 702 are installed on the outer side of one end of the collection box 701. Through the installation of the collection box 701, it is beneficial to install the filter cotton 703. By inserting the collection box 701 into the inner bottom of the water storage tank 1, it is beneficial to collect the liquid medicine for spraying the circuit board. The liquid medicine is filtered by the filter cotton 703 to remove the debris for film stripping, and the filtered liquid medicine flows into the bottom of the water storage tank 1 and is pumped out again by the water pump 501 for spraying. Through the installation of the handles 702, it is beneficial to hold and disassemble the collection box 701. Through the installation of the sealing ring 704, it is beneficial to play a sealing role after the collection box 701 is inserted into the water storage tank 1 to prevent the liquid medicine from overflowing.

[0048] Specifically, as Figure 10 and Figure 11As shown, the locking mechanism 8 includes a fixed block 801.

The opposite ends of the symmetric limit rods 810 are respectively hemispherical structures. The opposite ends of the two limit rods 810 extend into the driving grooves 808. The other ends of the two limit rods 810 respectively extend to the outside of the fixed block 801. A connecting block 802 is installed on the outside of the fixed block 801. The connecting block 802 is connected to the connecting shaft 804. The connecting block 802 is rotatably connected to the outside of the fixed block 801 through the connecting shaft 804. After the collection box 701 is inserted into the water storage tank 1, by rotating the connecting block 802, the connecting block 802 drives the turntable 807 to rotate through the connecting shaft 804, so that the driving grooves 808 at the edge of the turntable 807 abut against the limit rods 810. Since one end of the limit rod 810 is a hemispherical structure, the limit rod 810 is abutted and slides out of the elastic force of the compression spring 806, so that after the two limit rods 810 slide out, they are inserted into the limit grooves 805, thereby limiting between the collection box 701 and the water storage tank 1. By rotating the connecting block 802 in the reverse direction, the driving grooves 808 on the turntable 807 are aligned with the limit rods 810, which is convenient for the limit rods 810 to reset and contract, and then the collection box 701 is pulled out.

[0049] Specifically, as Figure 11 shown, symmetrically distributed positioning grooves 809 are provided at the edge of the turntable 807. The diameter of the positioning groove 809 is smaller than the diameter of the driving groove 808. The positioning groove 809 and the driving groove 808 are both arc-shaped structures. Through the opening of the positioning groove 809, it is beneficial that after the turntable 807 rotates a certain angle and abuts against the limit rod 810, the limit rod 810 can be engaged with the inside of the positioning groove 809, thereby playing a positioning role and preventing the turntable 807 from rotating randomly. Through the design of the arc-shaped structures of the driving groove 808 and the positioning groove 809, it is beneficial to smoothly drive and control the limit rod 810.

[0050] Specifically, as Figure 10 、 Figure 12 and Figure 13As shown, the sealing mechanism 9 includes an air storage bag 902.

One end of the air guide pipe 905 is connected to the sealing ring 704. At the center of the inside of one side wall of the collection box 701, a driving disk 901 is rotatably connected. At the center of one side of the driving disk 901, it is connected to the connecting shaft 804. At the edge of the driving disk 901, symmetric grooves 903 are provided. The opposite ends of the two top plates 904 are arc - shaped structures. The opposite ends of the two top plates 904 respectively abut against the inside of the grooves 903. The grooves 903 are arc - shaped structures. Through the installation of the two air storage bags 902, it is beneficial to store gas. When the connecting shaft 804 controls the turntable 807 to lock the collection box 701, the connecting shaft 804 synchronously controls the driving disk 901 to rotate. The grooves 903 on the side wall of the driving disk 901 abut against the ejector rod. Since one end of the top plate 904 is an arc - shaped structure, the top plate 904 is abutted and slides by the grooves 903, thereby enabling the top plate 904 to squeeze the air storage bag 902, making the gas inside the air storage bag 902 enter the inside of the sealing ring 704. The sealing ring 704 expands and fits tightly against the inner side of the water storage tank 1, making the sealing performance better.

[0051] When the present invention is in use, first, through the installation of multiple support frames 201, it is beneficial to stably support and place the water storage tank 1. And through the installation of multiple rollers 206, it is beneficial to connect the conveyor belt 203. Through the installation of multiple pressure wheels 207, it is beneficial to extrude the edge of the conveyor belt 203, so that the conveyor belt 203 can be discharged in an inverted "convex" shape inside the water storage tank 1. Through the operation of multiple first motors 202, it is beneficial to drive and control the conveyor belt 203, and then convey the circuit board well to be soaked and degreased in the liquid medicine at the bottom of the water storage tank 1. Through the installation of the protective cover 204, it is beneficial to shield and protect both ends of the top of the water storage tank 1. Through the connection of the control valve 205 with the external pipeline, it is beneficial to convey the liquid medicine to the water storage tank 1, facilitating the filling or discharging of the liquid medicine. Through the installation of multiple symmetric fixing seats 302, it is beneficial to install multiple symmetric clamping plates 301. Under the resistance of the compression spring 304, the two sliders 303 will drive the two clamping plates 301 to approach each other, thereby realizing stable clamping of the circuit board. Through the opening of the guide groove 305, it is beneficial for the circuit board to be inserted between the two clamping plates 301. Through the vertical clamping between the circuit board and the two clamping plates 301, the conveyor belt 203 conveys the circuit board into the water storage tank 1 for degreasing. Through the vertical placement of the circuit board, it is beneficial for the waste liquid to be well discharged and not easily remain. Through the installation of the driving rod 403, it is beneficial to drive and control one of the clamping plates 301. When the conveyor belt 203 moves to a certain position, the driving rod 403 outside the clamping plate 301 abuts against the clamping plate 402, and the driving rod 403 is abutted to squeeze the clamping plate 301, so that the clamping plate 301 drives the slider 303 to slide out of the elastic force of the compression spring 304, realizing the separation of the two clamping plates 301, facilitating the loading or taking out of the circuit board. After the conveyor belt 203 moves to a certain position again, the driving rod 403 separates from the clamping plate 402, and the clamping plate 301 resets. The two clamping plates 301 approach to stably clamp the circuit board, facilitating subsequent degreasing. Through the installation of the guide wheel 404, when the driving rod 403 abuts against the clamping plate 402, it plays a guiding role and makes the driving rod 403 not wear. At the same time, through the installation of the mounting block 401, it is beneficial for the clamping plate 402 and the mounting block 401 to be detachably connected through the card slot 405, facilitating subsequent maintenance. Through the installation of the water pump 501, it is beneficial to extract the filtered liquid medicine inside the bottom of the water storage tank 1 and convey it through the connecting pipe 505 to the inside of multiple conveying pipes 502. And the multiple conveying pipes 502 make the liquid medicine spray out through the spray holes 504 on one side of the vertical plate 503, which is beneficial to spray both sides of the circuit board conveyed on the conveyor belt 203, so that the circuit board can be better degreased. Through the installation of multiple groups of symmetric second motors 601, it is beneficial to connect the rotating shafts 604, and then realize the installation of multiple groups of symmetric scraping plates 602. Through the rotation of multiple groups of second motors 601, the rotation control of multiple groups of symmetric scraping plates 602 is realized. The scraping plates 602 are located at the bottom of the conveyor belt 203, which is beneficial to scrape off the residual film on both sides of the sprayed circuit board, making the degreasing effect better. Through the installation of the control board 605,It is convenient to control the rotating shaft 604. Through the sliding connection between the output shaft of the second motor 601 and the inside of the rotating shaft 604, under the control of the two electric push rods 606, the position of the control board 605 is controlled, so that the control board 605 drives the rotating shaft 604 to slide on the motor output shaft, thereby adjusting the position of the scraper 602 and the circuit board, which is convenient for scraping circuit boards of different thicknesses and preventing damage to the circuit board. The installation of the collection box 701 is convenient for the installation of the filter cotton 703. The collection box 701 is inserted into the inner side of the bottom of the water storage tank 1, which is convenient for collecting the liquid spraying the circuit board, and the liquid is filtered and defilmed through the filter cotton 703. The filtered liquid medicine flows into the bottom of the water storage tank 1 and is pumped out by the water pump 501 for spraying again. The installation of the handle 702 facilitates the holding and disassembly of the collection box 701. The installation of the sealing ring 704 facilitates the collection box 701 to be inserted into the water storage tank 1 to play a sealing role to prevent the liquid medicine from overflowing. After the collection box 701 is inserted into the water storage tank 1, the connection block 802 is rotated, and the connection block 802 drives the turntable 807 to rotate through the connecting shaft 804, so that the driving groove 808 at the edge of the turntable 807 is in conflict with the limit rod 810. Since one end of the limit rod 810 is a hemispherical structure, the limit rod 810 is resisted. The contactor 807 is freed from the elastic force of the squeezing spring 806 and slides out, so that the two limiting rods 810 slide out and insert into the limiting groove 805, thereby limiting the position between the collection box 701 and the water storage tank 1. By rotating the connecting block 802 in the opposite direction, the driving groove 808 on the turntable 807 is aligned with the limiting rod 810, which is convenient for the limiting rod 810 to reset and shrink, and then the collection box 701 is drawn out. Through the opening of the positioning groove 809, it is convenient for the turntable 807 to rotate a certain angle to contact the limiting rod 810, and the limiting rod 810 can be engaged with the inside of the positioning groove 809, thereby playing a positioning role, so that the turntable 807 will not rotate at will. The design of the arc structure facilitates the smooth driving control of the limit rod 810. The installation of two air storage bags 902 facilitates the storage of gas. When the rotating disk 807 is locked to the collection box 701 by the connecting shaft 804, the connecting shaft 804 synchronously controls the driving disk 901 to rotate, and the groove 903 on the side wall of the driving disk 901 resists the top rod. Since one end of the top plate 904 is an arc structure, the top plate 904 is resisted and slid by the groove 903, so that the top plate 904 squeezes the air storage bag 902, so that the gas inside the air storage bag 902 enters the inside of the sealing ring 704, and the sealing ring 704 expands and fits tightly with the inner side of the water storage tank 1, so that the sealing performance is better.
