A drying rack 209 is fixedly connected to the right side of the left second support plate 208 and the left side of the right second support plate 208; The cable is cured by the curing device 202 and placed on the drying rack 209. During the curing process, the cylinder 220 starts to work and the lifting plate 206 is lowered by the limit of the slide 205, so that the drying rack 209 drives the cable to descend, so that the cable can be cured more evenly.

[0022] The bottom of the workbench 201 is fixedly connected to a fixing ring 214, the bottom of the fixing ring 214 is fixedly connected to an air storage box 213, the top of the fixing ring 214 is fixedly connected to a cylinder body 215, the surface of the cylinder body 215 is fixedly connected to the inner wall of the workbench 201, the top of the cylinder body 215 is provided with a limiting groove 216, the groove wall of the limiting groove 216 is slidably connected to a slider 217, the top of the slider 217 is fixedly connected to a support rod 218, the top of the support rod 218 is fixedly connected to a third support plate 210, the top of the third support plate 210 is fixedly connected to a push plate 211, the position and number of the push plate 211 match the hole position on the drying rack 209, the front and rear sides of the top of the lifting plate 206 are penetrated by connecting holes 219, and the front and rear sides of the top of the support rack 204 are fixedly connected to a connecting shell 221; A gas storage bag 222 is provided inside the connecting shell 221. The gas outlet of the gas storage bag 222 is fixedly connected to an outlet pipe 223. The surface of the outlet pipe 223 is fixedly connected to the inner wall of the connecting hole 219. The bottom of the outlet pipe 223 is fixedly connected to the connecting pipe 212. One end of the connecting pipe 212 is connected to the interior of the gas storage box 213. The air outlet pipe 223 is pulled down by the lifting plate 206, so that the air outlet pipe 223 pulls the gas storage bag 222 down, so that the connecting shell 221 squeezes the gas storage bag 222, and the gas in the gas storage bag 222 is discharged into the gas storage box 213 through the air outlet pipe 223 and the connecting pipe 212, so that the gas is discharged from the cylinder 215, and the gas pushes the slider 217 to move upward, so that the support rod 218 drives the third support plate 210 and the push plate 211 to move upward, avoiding the adhesion of the cable, and the plastic liquid will not stick to the drying holes on the drying rack 209, avoiding the bottom of the cable from being completely dried due to the blockage of the drying holes.

[0023] The top of the support frame 204 is fixedly connected to a cylinder 220, and the extended end of the cylinder 220 passes through the support frame 204 and is fixedly connected to the top of the lifting plate 206; By setting up the cylinder 220, the equipment can complete the adjustment of the wiring position, and through the cooperation between the air outlet pipe 223, the gas storage bag 222, the connecting shell 221, the connecting pipe 212, the gas storage box 213, the cylinder body 215 and the slider 217, the gas inside the gas storage box 213 can complete self-circulation, which can reduce the connection of the external air pump and reduce production costs.

[0024] There are two cylinders 220 , and the two cylinders 220 are symmetrically distributed on the left and right.

[0025] exist Figure 6In the figure, the positional relationship between the cylinder body 215 and the fixing ring 214 is shown in the form of an exploded diagram. In actual circumstances, the cylinder body 215 passes through the top platform of the workbench 201 and is fixedly connected to the top of the fixing ring 214 fixedly connected to the bottom of the top platform of the workbench 201.

[0026] In this solution, when an FFC cable for a liquid crystal display is in use, a signal passes through the input point 101. The signal at the input point 101 passes through the first resistor 102. The signal at the first resistor 102 is first amplified by the first amplifier 104. At this time, the first situation occurs. The signal is too large. The signal is derived through the first amplifier 104, passes through the second capacitor 105, and is derived from the signal grounding point. When the signal is normal, the signal first passes through the first connection point 106. At this time, the second situation occurs. The signal amplitude is slightly smaller than the first situation. At this time, the signal first passes through the first diode 108 and then passes through the second diode 109 to complete the signal processing. In this case, the signal is at a normal value and is located at the second connection point 107. Therefore, the third situation occurs, where the signal current is too large. The signal is first amplified by the second amplifier 110 and then stabilized by the third resistor 111, so that the signal is stably output through the output point 112. When the signal is normal, it is directly amplified by the third amplifier 113 and then output through the output point 112. In the last situation, when there is no problem with the signal, the signal is directly output from the output point 112 after being stabilized by the first resistor 102. This wiring circuit effectively improves the transmission of signals through the wiring, making it easier to use the wiring. During the production of the cable, the cable is cured by the curing device 202 and placed on the drying rack 209. At this time, the cable is cured by the curing device 202. During the curing process, the cylinder 220 starts to work and the lifting plate 206 is lowered through the limit of the slide 205, so that the lifting plate 206 pulls the air outlet pipe 223 to drop, so that the air outlet pipe 223 pulls the gas storage bag 222 to drop, so that the connecting shell 221 squeezes the gas storage bag 222, and the gas in the gas storage bag 222 is discharged through the air outlet pipe 223 and the connecting pipe 212. The gas enters the gas storage box 213 so that the gas is discharged from the cylinder 215, and the gas pushes the slider 217 to move upward, so that the support rod 218 drives the third support plate 210 and the push plate 211 to move upward, thereby preventing the cable from sticking and the plastic liquid from sticking to the drying holes on the drying rack 209, thereby preventing the bottom of the cable from being completely dried due to the blockage of the drying holes. In addition, through the cooperation among the gas outlet pipe 223, the gas storage bag 222, the connecting shell 221, the connecting pipe 212, the gas storage box 213, the cylinder 215 and the slider 217, the gas After the discharge is completed, the cylinder 220 is reset, driving the lifting plate 206 and the drying rack 209 to reset. The lifting plate 206 and the drying rack 209 are reset while completing the uniform drying operation of the cable. The present application also drives the lifting plate 206 and the drying rack 209 to move back and forth by the cylinder 220, so that the cable is evenly heated, thereby improving the efficiency of the curing device 202 in curing the cable. When the cylinder 220 is reset, it will drive the outlet pipe 223 and the gas storage bag 222 to reset, and at the same time, it is supported by the third support plate 210 and the push plate 211. Due to the influence of gravity, the support rod 218 drives the slider 217 to descend, so that the gas returns to the inside of the gas storage box 213, and then enters the gas storage bag 222 through the outlet pipe 223 and the connecting pipe 212, completing the gas recovery, and the gas storage bag 222 is reset to the inside of the connecting shell 221. When the gas flows back to the gas storage bag 222, the connecting shell 221 will not limit the recovery of the gas storage bag 222, so that the gas inside the gas storage box 213 can complete self-circulation, which can reduce the access of external air pumps and reduce production costs.

[0027] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations can be made to the embodiments without departing from the principles and spirit of the invention.
