[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Specific examples are given below.

[0033] See also Figure 1-Figure 5 The utility model provides a circuit board DES line developing etching film stripping device, comprising a film stripping basin 1; a first support frame 2, fixedly mounted on the outer surface of the film stripping basin 1; a moving mechanism 3, rotatably mounted on one side of the first support frame 2; a liquid spraying mechanism 4, fixedly mounted on one side of the film stripping basin 1; a turning mechanism 5, fixedly mounted on the bottom wall of the inner surface of the film stripping basin 1; a supporting mechanism 6, fixedly mounted on the inner cavity of the film stripping basin 1;

[0034] The liquid spraying mechanism 4 comprises a water pump 41, the water inlet end of the water pump 41 is fixedly mounted on one side of the film stripping basin 1, the water outlet end of the water pump 41 is fixedly connected with a telescopic tube 42, one end of the telescopic tube 42 is fixedly connected with a transverse tube 44, two cylinders 43 are fixedly connected to the outer surface of the transverse tube 44, one end of the cylinder 43 is fixedly connected with a cross beam 37, a first groove 38 is formed on the top of the cross beam 37, the telescopic tube 42 is fixedly mounted on the inner surface of the first groove 38, and a plurality of nozzles 45 are fixedly connected to the bottom of the transverse tube 44.

[0035] When stripping a circuit board, it is necessary to spray a stripping liquid onto the surface of the circuit board. The stripping liquid sprayed by a common stripping liquid spraying device is not uniform enough to make the entire circuit board contaminated with the stripping liquid.

[0036] First, the circuit board is placed on the support mechanism 6. Before the water pump 41 is started, the heating component in the support mechanism 6 can increase the temperature of the film stripping liquid. When the film stripping liquid is heated, the chemically active substances in it will be more active, and the reaction speed between the film layer and the film layer will be accelerated, thereby improving the film stripping effect. The water pump 41 pumps the film stripping liquid stored in the film stripping basin 1 to the horizontal pipe 44 through the telescopic pipe 42, and the film stripping liquid is sprayed out by the nozzle 45. The nozzle 45 can spray the film stripping liquid onto the surface of the circuit board. Since the horizontal pipe 44 is connected to a plurality of nozzles 45, the film stripping liquid can be sprayed onto the entire circuit board surface.

[0037] When placing the circuit board, the cylinder 43 raises the position of the nozzle 45 to facilitate the placement of the circuit board. After the placement is completed, the cylinder 43 lowers the height of the nozzle 45 to make the nozzle 45 closer to the circuit board, thereby preventing the defilming liquid from spilling out of the defilming basin 1 when spraying the circuit board. After defilming one side of the circuit board is completed, the flipping mechanism 5 flips the circuit board over and sprays the defilming liquid on the other side of the circuit board.

[0038] Further, such as Figure 2 and Figure 3 As shown, there are two first support frames 2, and the two first support frames 2 are respectively fixedly mounted on both sides of the film stripping basin 1, and the opposite surfaces of the two first support frames 2 are provided with slide grooves 21, and the moving mechanism 3 includes a first threaded rod 31, and the first threaded rod 31 is rotatably mounted on the inner surface of the slide groove 21 and one end passes through and extends out of the first support frame 2, and the first threaded rod 31 extending out of the first support frame 2 is fixedly connected with a pulley 32, and the outer surfaces of the two pulleys 32 are commonly wound and connected with a belt 35, a connecting plate 34 is fixedly mounted on one side of the first support frame 2, and a first motor 33 is fixedly mounted on the top of the connecting plate 34, and the output shaft of the first motor 33 is fixedly connected to one side of the pulley 32, and two second grooves 39 are provided on one side of the crossbeam 37, and the two first threaded rods 31 are respectively threadedly mounted on the inner surface of the second groove 39, and the crossbeam 37 is slidably mounted on the inner surface of the slide groove 21.

[0039] Since the circuit board is relatively large, it is necessary to adjust the position of the mechanism for spraying the defilming liquid when spraying the defilming liquid, start the first motor 33, and the output shaft of the first motor 33 drives the pulley 32 on the same side to rotate, and drives the pulley 32 on the other side to rotate through the belt 35. The two pulleys 32 drive the two first threaded rods 31 to rotate, and the two first threaded rods 31 can slide on the inner surface of the slide groove 21 with the cross beam 37. The nozzle 45 is installed at the bottom of the cross beam 37, so the rotation of the first threaded rod 31 can adjust the position of the nozzle 45.

[0040] Further, such as Figure 4As shown, the flip mechanism 5 includes a first electric telescopic rod 51, which is fixedly mounted on the bottom wall of the inner surface of the film stripping basin 1, a second motor 52 is fixedly mounted on the top of the first electric telescopic rod 51, an output shaft of the second motor 52 is fixedly connected to a second electric telescopic rod 53, and one end of the second motor 52 is fixedly connected to a first slide plate 54;

[0041] A fixing plate 55 is fixedly installed at the bottom of one side of the first slide plate 54, and two limit blocks 56 are fixedly installed on the first slide plate 54 on the same side. A second slide plate 57 is slidably installed on the surface of the first slide plate 54 on the same side. Limiting grooves 571 are provided on both sides of the second slide plate 57, and the two limit blocks 56 are slidably installed on the inner surfaces of the limiting grooves 571 respectively.

[0042] A fourth groove 572 is defined at the bottom of the second slide plate 57, a third groove 551 is defined at the bottom of the fixed plate 55, a second threaded rod 58 is rotatably mounted on the inner surface of the third groove 551, the second threaded rod 58 is threadedly mounted on the inner surface of the fourth groove 572, a third motor 59 is fixedly connected to the bottom of the second threaded rod 58, and the third motor 59 is fixedly mounted on one side of the first slide plate 54.

[0043] In order to spray the film stripping liquid on both sides of the circuit board, the circuit board needs to be turned over. When the film stripping liquid is sprayed on the first side of the circuit board, the first electric telescopic rod 51 and the second electric telescopic rod 53 are both in a retracted state. When the circuit board needs to be turned over, the first electric telescopic rod 51 is first extended to make the circuit board located on the upper part of the fixed plate 55 and the lower part of the second slide plate 57. Then the second electric telescopic rod 53 is extended to make both sides of the circuit board located between the fixed plate 55 and the second slide plate 57. The third motor 59 rotates with the second threaded rod 58, and the second slide plate 57 slides downward along the two limit blocks 56 to clamp the circuit board. The second motor 52 is started to turn the clamped circuit board over.

[0044] After the flipping is completed, the third motor 59 rotates in the opposite direction to release the restraint on the circuit board. In order to prevent the components in the flipping mechanism 5 from affecting the liquid spraying process, the second electric telescopic rod 53 and the first electric telescopic rod 51 are retracted in sequence.

[0045] Further, such as Figure 5 As shown, the support mechanism 6 includes a plurality of electric heating tubes 61, and the plurality of electric heating tubes 61 are evenly installed in the inner cavity of the film stripping basin 1. Two second support frames 62 are fixedly installed on the bottom wall of the inner surface of the film stripping basin 1, and friction plates 63 are fixedly installed on the tops of the two second support frames 62.

[0046] In order to speed up the film stripping process, the film stripping liquid in the film stripping basin 1 is heated. When the film stripping liquid is at a high temperature, the chemically active substances therein will be more active, and the reaction speed with the film layer will be accelerated, thereby improving the film stripping effect. In order to prevent the circuit board from moving when the film stripping liquid is sprayed on the circuit board, a friction plate 63 is installed on the second support frame 62 so that the circuit board can be placed on the second support frame 62 more firmly.

[0047] Working principle: firstly, the stripping liquid in the stripping basin 1 is heated by the electric heating tube 61, and then the circuit board is placed on the second support frame 62, and the first motor 33 drives the two first threaded rods 31 to rotate so that the crossbeam 37 can move with the nozzle 45 above the circuit board, so that the stripping liquid can be sprayed to the entire circuit board;

[0048] After the film is removed from one side of the circuit board, the third motor 59 drives the second threaded rod 58 to rotate so that the fixed plate 55 and the second slide plate 57 are close to each other to clamp the circuit board, and the second motor 52 drives the first slide plate 54 to rotate to flip the circuit board, and then the nozzle 45 sprays the film removal liquid to the other side of the circuit board to remove the film from the circuit board.

[0049] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
