Description

Technical Field

[0001] The invention relates to the technical field of dry film slitting devices, and in particular to a dry film slitting component with a deviation correction function. Background Art

[0002] Dry film is relative to wet film. Dry film is a kind of polymer material. After being irradiated by ultraviolet rays, it can produce a polymerization reaction to form a stable substance attached to the board surface, thereby achieving the function of blocking electroplating and etching. Dry film is an important consumable material for making printed circuit boards and is widely used in the microelectronics industry and circuit board manufacturing industry.

[0003] In the dry film production process, due to the long width of the dry film, after the dry film production is completed, the dry film is generally moved directly to the slitting assembly for slitting, so that the dry film is slit into suitable widths for winding. When slitting the dry film, an infrared sensor is generally used to correct the dry film to prevent position deviation during the dry film slitting process.

[0004] The existing dry film correction device generally places an infrared sensor on the side of the dry film to detect the position of the dry film. However, the dry film is generally made by an extruder. After the dry film is produced, there may be certain errors in the width of each part of the dry film, which may cause the infrared sensor to detect the position of the dry film to have certain deviations. After the dry film is produced, the outer edge of the dry film may be bent due to temperature or foreign objects, which may cause the infrared sensor to detect the position of the dry film to have certain deviations, ultimately resulting in poor correction effect of the correction device on the dry film position.

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] The present invention provides a technical solution: referring to Figure 1-10 The present invention discloses a dry film slitting component with a correction function, comprising two support plates 1 installed on the dry film slitting component, a correction mechanism 2 is arranged between the two support plates 1, the correction mechanism 2 comprises a transparent tube 21, both ends of the transparent tube 21 slide through the two support plates 1 respectively, a detection part 23 is arranged on the inner and outer sides of the support plates 1, and an adjustment part 24 is arranged on both ends of the transparent tube 21, a monitoring mechanism 3 is arranged on the outer peripheral side of the correction mechanism 2, and a cooling mechanism 4 is arranged on the left side of the two support plates 1.

[0020] In this embodiment, during the dry film slitting process of the improved dry film slitting assembly, the infrared rays of the detection member 23 pass through the transparent tube 21 and irradiate on the dry film. While detecting the width of the dry film, the transparent tube 21 is pushed to move back and forth by the adjusting member 24, and the position of part of the dry film between the two support plates 1 is synchronously adjusted based on the center line of the dry film through the friction between the transparent tube 21 and the dry film, so that the dry film is divided into several parts of specific width, and during the movement of the dry film, the adjusting member 24 synchronously drives the transparent tube 21 to rotate, so that there is no mutual friction between the dry film and the outer peripheral wall of the transparent tube 21, which causes the outer wall of the dry film to be damaged, and the rotating transparent tube 21 synchronously drives the monitoring member 23 to move back and forth, and the adjusting member 24 synchronously drives the transparent tube 21 to rotate, so that the outer wall of the dry film is not damaged due to mutual friction between the dry film and the outer peripheral wall of the transparent tube 21. The mechanism operates to monitor the moving length of the dry film, so that the operation of the device is stopped after the winding length of the dry film after slitting reaches the required value, and the dry film is cut off to form a dry film roll of a specific length and a specific width. At the same time, the rotating transparent tube 21 synchronously drives the cooling mechanism 4 to operate, and forms an airflow on the top side of the dry film to cool the dry film, and blows the high-speed airflow on the two side edges of the dry film to flatten the bent side edges of the dry film, and then the dry film is directly moved to the transparent tube 21. The dry film is maintained in a straight state through the mutual interference between the dry film and the transparent tube 21, so that the detection member 23 monitors the straight dry film to avoid the bending of the side edges of the dry film affecting the accuracy of the detection of the dry film by the detection member 23.

[0021] In a further preferred embodiment of the present invention, Figure 5 and Figure 8 As shown, the detection member 23 includes an infrared transmitter 231 and an infrared receiver 232. The infrared transmitter 231 is arranged in the transparent tube 21, and the infrared receiver 232 is arranged above the transparent tube 21 at a position corresponding to the infrared receiver 232. The infrared transmitter 231 is matched with the inner wall of the transparent tube 21, and both ends of the infrared receiver 232 are fixedly connected to the two support plates 1 by bolts. In this embodiment, during the movement of the dry film, the infrared transmitter 231 emits a linear infrared light band in the direction of the infrared receiver 232. Due to the obstruction of the dry film, the infrared receiver 232 can only receive part of the infrared rays, so that the width of the dry film at that position is determined by the spacing between the light bands received by the infrared receiver 232, and the width of the light bands on both sides of the dry film is received by the infrared receiver 232 to monitor the position of the dry film between the two support plates 1. Finally, the position of the dry film between the two support plates 1 is adjusted based on the center line of the dry film.

[0022] In a further preferred embodiment of the present invention, Figure 5As shown, the adjusting member 24 includes two electric telescopic rods 242, two supporting frames 233 are provided at opposite ends of the infrared emitter 231, and the upper and lower ends of each supporting frame 233 are respectively fixedly connected with the infrared emitter 231 and the corresponding supporting plate 1 by bolts, and the two electric telescopic rods 242 are relatively fixedly installed on the supporting frame 233 at the position corresponding to the transparent tube 21, and the push rod of each electric telescopic rod 242 slides through the corresponding supporting frame 233 and contacts with the transparent tube 21; In this embodiment, when the position of the dry film is adjusted, the electric telescopic rods 242 at both ends are stretched or contracted respectively, thereby pushing the transparent tube 21 to slide back and forth, and the dry film on the transparent tube 21 is driven to move synchronously through the friction between the transparent tube 21 and the dry film, thereby correcting the position of the dry film, so that there will be no position deviation when the dry film is cut.

[0023] In a further preferred embodiment of the present invention, Figure 3 , Figure 6 and Figure 7 As shown, a motor 241 is fixedly mounted on the inner wall of the support frame 233, a first gear rod 244 is fixedly mounted on the driving end of the motor 241, and gear rings 243 are fixedly sleeved on both ends of the transparent tube 21, and the gear rings 243 are meshedly connected with the corresponding first gear rods 244; In this embodiment, when the dry film moves, the motor 241 drives the first gear rod 244 to rotate rapidly, thereby driving the transparent tube 21 to rotate synchronously with the movement of the dry film through the gear ring 243, thereby preventing the dry film from rubbing against the outer wall of the transparent tube 21 and causing damage to the surface of the dry film.

[0024] In a further preferred embodiment of the present invention, Figure 6 and Fig.10 As shown, the monitoring mechanism 3 includes a second gear rod 31, which is meshed and mounted on the top side of the corresponding gear ring 243, and the second gear rod 31 is rotatably connected to the corresponding support plate 1 through a rotating shaft and a bearing, a fixed cylinder 32 is provided on the outer peripheral side of the second gear rod 31, and the fixed cylinder 32 is fixedly connected to the corresponding support plate 1, and a piston rod 33 is slidably mounted in an opening at one end of the fixed cylinder 32, one end of the piston rod 33 is hemispherical, and the hemispherical end of the piston rod 33 is inserted into the corresponding tooth groove of the corresponding second gear rod 31; In this embodiment, during the rotation of the gear ring 243, the second gear rod 31 will be driven to rotate synchronously. Due to the mutual interference between the inclined inner wall of the tooth groove of the second gear rod 31 and the spherical surface of the piston rod 33, the piston rod 33 is pushed into the fixed tube at a uniform reciprocating speed, thereby compressing the air in the fixed tube. When the piston rod 33 is aligned with the tooth groove, the piston rod 33 is pushed by the gas inside the fixed tube, so that the piston rod 33 is automatically inserted into the tooth groove of the second gear rod 31. The operator does not need to perform other operations, and there is no need to set up an additional power source.

[0025] In a further preferred embodiment of the present invention, Fig.10 As shown, a pressure sensor 34 is fixedly installed in the cylinder cover at the other end of the fixed cylinder 32, and the detection end of the pressure sensor 34 is inserted into the corresponding fixed cylinder 32; In this embodiment, when the piston rod 33 is retracted into the fixed tube 32, it compresses the air in the fixed tube, so that the pressure sensor 34 detects the increase in air pressure in the fixed tube. The rotation speed of the gear ring 243 and the transparent tube 21 can be determined according to the frequency of air pressure change in the fixed tube, thereby determining the moving length of the dry film and the length of the dry film winding.

[0026] In a further preferred embodiment of the present invention, Fig. 9 As shown, a square tube 41 in an L-shape is provided on one side of the second gear rod 31 away from the support plate 1, and the square tube 41 is fixedly connected to the corresponding support plate 1 through a connecting rod, an impeller 42 is provided in the air inlet of the square tube 41, and the driving end of the impeller 42 rotates through the tube wall of the corresponding square tube 41 and is fixedly connected to the corresponding second gear rod 31; In this embodiment, during the rapid rotation of the second gear rod 31, the gas in the opening of the square tube 41 can be pushed into the square tube 41 and a negative pressure state is continuously formed in the opening of the square tube 41, so that external gas can continuously flow into the opening of the square tube 41 to replenish the gas lost in the opening of the square tube 41. The operator does not need to perform other operations, nor does it need to set up an additional power source.

[0027] In a further preferred embodiment of the present invention, Figure 1 , Figure 2 and Fig. 9 As shown, the top of the square tube 41 is connected to a soft tube 43, and an exhaust pipe 44 is relatively fixedly installed on the housing of the infrared receiver 232 by bolts. A plurality of exhaust holes 45 are relatively opened on the front and rear sides of the exhaust pipe 44, and each exhaust hole 45 is inclined. The exhaust end of the soft tube 43 is inserted into the corresponding exhaust pipe 44 and fixedly connected to the wall of the corresponding exhaust pipe 44. In this embodiment, while the external airflow flows into the square tube 41, the gas in the square tube 41 flows into the exhaust pipe 44 through the soft tube 43 and is discharged from the exhaust holes 45 to form multiple strong airflows blowing on the dry film. The gas discharged from the exhaust holes 45 on the opposite sides of the two exhaust holes 45 blows on the dry film to reduce the temperature of the dry film, and the high-speed airflow discharged from the exhaust holes 45 on the opposite sides of the two exhaust holes 45 blows on the side of the dry film. When the side of the dry film part is folded, the bent outer edge of the dry film part is flattened by the blowing of the high-speed flowing airflow, and then the dry film moves to the top of the transparent tube 21. Due to the mutual interference between the outer peripheral wall of the transparent tube 21 and the dry film, the outer edge of the dry film will not be deformed, bent and reset, so that the infrared transmitter 231 and the infrared receiver 232 can detect the straight dry film.

[0028] Working principle: Before using the improved dry film slitting assembly, the operator first unscrews the bolts on the infrared transmitter 231, thereby adjusting the distance between the infrared transmitter 231 and the transparent tube 21 according to the thickness of the dry film, and then passes the produced dry film through the gap between the transparent tube 21 and the infrared receiver 232, and makes the dry film fit closely with the outer wall of the transparent tube 21, so that the dry film slightly conflicts with the outer wall of the transparent tube 21, and then unscrews the bolts on the exhaust pipe 44 and adjusts the connection position of the exhaust pipe 44 and the infrared receiver 232 according to the width of the dry film, thereby adjusting the distance between the two exhaust pipes 44, so that the air discharged from the exhaust holes 45 on the opposite sides of the two exhaust pipes 44 can be blown on the two sides of the dry film, and then the dry film is inserted into the slitting mechanism of the dry film slitting assembly for slitting of the dry film, and finally the winding mechanism in the dry film slitting assembly is used to roll up the slitting dry film; During the movement of the dry film, the motor 241 drives the first gear rod 244 to rotate rapidly, thereby driving the transparent tube 21 to rotate synchronously with the movement of the dry film through the gear ring 243, so as to avoid the friction between the dry film and the outer wall of the transparent tube 21, which may cause the surface of the dry film to be damaged; During the rotation of the transparent tube 21, the infrared transmitter 231 emits a linear infrared light band toward the infrared receiver 232. Due to the shielding of the dry film, the infrared receiver 232 can only receive part of the infrared rays. While detecting the width of the dry film at this position, the position of the dry film between the two support plates 1 is monitored. During the above-mentioned dry film movement process, if the position of the dry film is offset, the electric telescopic rods 242 on both sides are activated to stretch or contract to push the transparent tube 21 forward or backward, and the dry film on the transparent tube 21 is driven to move synchronously through the friction between the transparent tube 21 and the dry film, so as to correct the position of the dry film, so that the cutting of the dry film will not have position deviation; It should be noted that, during the movement of the transparent tube 21, since the first gear rod 244 and the second gear rod 31 are relatively long, the movement of the transparent tube 21 within a certain range will not affect the meshing connection between the gear ring 243 and the first gear rod 244 and the second gear rod 31. During the rotation of the gear ring 243, the second gear rod 31 will be driven to rotate synchronously. Due to the mutual interference between the inclined inner wall of the tooth groove of the second gear rod 31 and the spherical surface of the piston rod 33, the piston rod 33 is pushed into the fixed tube at a uniform reciprocating speed, thereby compressing the air in the fixed tube, so that the pressure sensor 34 detects the increase of the air pressure in the fixed tube. The rotation speed of the gear ring 243 and the transparent tube 21 can be determined according to the frequency of the air pressure change in the fixed tube, thereby determining the moving length of the dry film and the length of the dry film winding, so that after the dry film is cut and wound to a specific length, the dry film can be cut to form a dry film roll with a specific width and a specific length; It should be noted that when the piston rod 33 is aligned with the tooth groove, the piston rod 33 is pushed by the gas inside the fixed tube, so that the piston rod 33 is automatically inserted into the tooth groove of the second gear rod 31; During the rapid rotation of the second gear rod 31, the gas in the opening of the square tube 41 can be pushed into the square tube 41 and a negative pressure state is continuously formed in the opening of the square tube 41, so that the external gas continuously flows into the opening of the square tube 41 to supplement the gas lost in the opening of the square tube 41. At the same time, the gas in the square tube 41 flows into the exhaust pipe 44 through the soft tube 43 and is discharged from the exhaust hole 45 to form multiple strong airflows blowing on the dry film. The gas discharged from the exhaust holes 45 on the opposite sides of the two exhaust holes 45 blows on the dry film to reduce the temperature of the dry film, and the high-speed airflow discharged from the exhaust holes 45 on the opposite sides of the two exhaust holes 45 blows on the side of the dry film. When the side of the dry film part is folded, the bent outer edge of the dry film part is flattened by the blowing of the high-speed flowing airflow, and then the dry film moves to the top of the transparent tube 21. Due to the mutual interference between the outer peripheral wall of the transparent tube 21 and the dry film, the outer edge of the dry film will not be deformed, bent and reset, so that the infrared transmitter 231 and the infrared receiver 232 can detect the straight dry film. It should be noted that since the diameter of the exhaust hole 45 is too small, the amount of gas discharged from the exhaust hole 45 is limited, thereby forming a high-pressure state in the exhaust pipe 44. At this time, due to the pressure difference at both ends of the exhaust hole 45, the gas can pass through the exhaust hole 45 more quickly and blow onto the dry film.

The above embodiments and descriptions only describe the principles of the present invention.
