[0002] Metal sheets are common materials in industrial production and daily life. Whether it is used as decoration, protection or frame, metal sheets can be used to achieve functions. However, in the production of metal sheets, there are situations where multiple sizes are produced on the same line at the same time. At this time, it is necessary to equip corresponding dimension measuring devices to detect the size of metal sheets, which can not only verify the qualified rate of the sheets, but also prepare for subsequent packaging; the metal sheet size measuring devices in the existing technology usually cannot realize the continuous automatic measurement of the metal sheet size, and are too dependent on camera accuracy.

[0005] Furthermore, a limiting rod is slidably installed on the placement box, a retreat frame is fixedly installed on the limiting rod, a lower rack is fixedly installed on the retreat frame, an upper rack is fixedly installed on the extended push block, a docking gear, an upper acceleration gear and a lower acceleration gear are rotatably installed below the placement box, the docking gear is meshed with the upper rack, the upper acceleration gear is meshed with the docking gear, the upper acceleration gear is meshed with the lower acceleration gear, and the lower acceleration gear is meshed with the lower rack.

[0006] When the metal sheet is conveyed to the detection box, the bottom motor stops rotating, the bottom electric cylinder extends, and drives the extended push block to slide along the placement box, thereby driving the lifting block to move, and the lifting block lifts the upper block, so that the upper block lifts the metal sheet in the detection box. When there is no metal sheet in the detection box, when the upper block is lifted to the highest point, the upper surface of the upper block just contacts the lower surface of the upper top plate. When the upper block lifts the metal sheet, due to the thickness of the metal sheet, the metal sheet will push the upper top plate upward, and the lifting spring is compressed. At this time, the thickness measuring column rises, and the rising distance of the thickness measuring column is the thickness of the metal sheet, which is measured by the distance sensor at the top of the thickness measuring column. When the extended push block moves, the upper rack drives the docking gear to rotate, and the upper acceleration gear and the lower acceleration gear are accelerated, driving the lower rack, the back frame and the limit rod to slide outward, so that the stroke of the limit rod is greater than the stroke of the extended push block, so that when the metal sheet rises to contact with the upper top plate, the limit rod has been completely separated from the limit rod, and the roller has contacted with the side of the metal sheet.

[0007] Furthermore, the length and width mechanism includes a fixed seat fixedly installed below the disc frame, the material of the lower surface of the disc frame is copper, a top motor is fixedly installed on the disc frame, a motor gear is fixedly installed on the motor shaft of the top motor, a gear shaft is rotatably installed on the disc frame, an upper gear and a lower gear are fixedly installed on the gear shaft, the motor gear is meshed with the upper gear, a rotating frame is rotatably installed outside the fixed seat, a center gear is fixedly installed on the rotating frame, the center gear is meshed with the lower gear, two inner sliding rods are slidably installed in the rotating frame, an inward spring is arranged between the inner sliding rod and the rotating frame, a capacitor needle is fixedly installed on the inner sliding rod, the capacitor needle contacts with the lower surface of the disc frame, a roller is rotatably installed on the inner sliding rod, a limit rod is rotatably installed on the inner sliding rod, contact blocks are rotatably installed on the two limit rods, the contact blocks contact with the limit rod, and the inward spring is in a stretched state in the initial state.

[0008] Furthermore, a thickness measuring column is slidably installed in the fixed seat, an upper top plate is fixedly installed below the thickness measuring column, a lifting spring is arranged between the upper top plate and the fixed seat, and a distance sensor is arranged on the top of the thickness measuring column.

[0009] As the limiting rod moves outward, the limiting rod will move away from the contact block. At this time, the retraction spring gradually rebounds, causing the inner slide rod, roller and capacitor needle to move inward. When the roller contacts the side of the metal plate, the retraction spring no longer rebounds, but still has elastic force. When the upper block rises to the highest point, the bottom electric cylinder stops for a short time, and the top motor controls the motor gear to rotate, thereby driving the upper gear, gear shaft and lower gear to rotate, thereby driving the center gear and rotating frame to rotate. Under the action of the retraction spring, the inner slide rod and the retraction spring slide together, and the roller is driven to circle around the outer wall of the metal plate. A pattern is formed through the capacitor needle and the lower surface of the disc frame, and is transmitted to the controller to obtain the length and width of the metal plate.

[0010] Furthermore, the conveying mechanism includes a plurality of feeding friction wheels rotatably mounted in the placement box, and two feeding friction wheels rotatably mounted on the detection box.

[0011] Furthermore, a bottom motor is fixedly installed at the bottom of the detection box, a bottom gear is fixedly installed on the motor shaft of the bottom motor, a lower docking gear is rotatably installed at the bottom of the detection box, an inner docking gear is fixedly installed on the lower docking gear, the bottom gear is meshed with the lower docking gear, a sliding seat is slidably installed at the bottom of the detection box, a sliding seat spring is arranged between the sliding seat and the detection box, a driving wheel and two driven wheels are rotatably installed on the sliding seat, a driving gear is fixedly installed on the driving wheel, the driving gear is meshed with the inner docking gear, a friction belt is wrapped around the driving wheel and the two driven wheels, and in the initial state, the friction belt forms a friction transmission with the feeding friction wheel closest to the detection box, and the friction belt forms a friction transmission with the delivery friction wheel.

[0012] Furthermore, an outlet plate is slidably mounted on the detection box, a friction strip and an opening are arranged on the outlet plate, a spring is arranged between the outlet plate and the detection box, a switch plate is rotatably mounted on the placement box, and a torsion spring is arranged between the switch plate and the placement box.

[0013] When in use, metal sheets are stacked in the placement box, and the bottom motor controls the rotation of the bottom gear, which drives the lower docking gear and the inner docking gear to rotate, thereby driving the driving gear and the driving wheel to rotate, thereby driving the friction belt to rotate, and the friction belt drives the feeding friction wheel and the delivery friction wheel closest to the detection box to rotate through friction transmission, and the metal sheet of the bottom layer is transported toward the detection box through the feeding friction wheel. The metal sheet pushes the switch plate, so that the switch plate rotates relative to the placement box, and the torsion spring is twisted. When the metal sheet is transported to contact with the outlet plate, the bottom motor stops rotating, and the bottom electric cylinder begins to extend.

[0014] When the metal sheet measurement is completed, the bottom electric cylinder continues to extend, so that the lifting block reaches the rear of the upper lifting block. At this time, the metal sheet and the upper lifting block descend under the action of gravity, and the metal sheet falls back into the detection box. The extended push block continues to move forward and contacts the sliding seat, pushing the sliding seat to slide along the detection box. The sliding seat spring is compressed, so that the friction belt is separated from the feeding friction wheel, and the friction belt only forms a friction transmission with the feeding friction wheel. When the bottom electric cylinder is extended to the farthest, the extended push block pushes the sliding seat to the limit position. At this time, the friction belt contacts the friction strip to form a friction transmission. At this time, the bottom electric cylinder stops and the bottom motor starts to rotate. , causing the friction belt to rotate and drive the friction strip and the outlet plate to rise. The spring between the outlet plate and the detection box is compressed, causing the opening on the outlet plate to reach the front of the detection box. At the same time, the friction belt drives the delivery friction wheel to rotate, and the delivery friction wheel sends the metal sheet through the opening on the outlet plate and out of the detection box. The outlet plate is reset under the rebound of the spring, and then the bottom motor stops rotating, the bottom electric cylinder is quickly retracted, and the limiting rod pushes the contact block again, causing the inner slide rod to extend to the farthest again, the retraction spring is stretched and restored to the initial state, the sliding seat is reset under the rebound of the sliding seat spring, and the friction belt resumes contact with the feeding friction wheel.

[0030] When the metal sheet is conveyed to the detection box 113, the bottom motor 301 stops rotating, the bottom electric cylinder 103 extends, driving the extended push block 104 to slide along the placement box 101, thereby driving the lifting block 105 to move, and the lifting block 105 lifts the upper top block 106, so that the upper top block 106 lifts the metal sheet in the detection box 113. When there is no metal sheet in the detection box 113, when the upper top block 106 is lifted to the highest point, the upper surface of the upper top block 106 just contacts the lower surface of the upper top plate 207. When the upper top block 106 lifts the metal sheet, due to the thickness of the metal sheet, the metal sheet will push the upper top plate 207 upward, and the lifting spring 208 is The thickness measuring column 205 is compressed. At this time, the thickness measuring column 205 rises. The rising distance of the thickness measuring column 205 is the thickness of the metal plate, which is measured by the distance sensor on the top of the thickness measuring column 205. When the push block 104 is extended and moved, the docking gear 108 is driven to rotate through the upper rack 107, and the upper acceleration gear 109 and the lower acceleration gear 110 are accelerated to drive the lower rack 111, the retreat frame 112 and the limiting rod 102 to slide outward, so that the stroke of the limiting rod 102 is greater than the stroke of the extended push block 104, so that when the metal plate rises to contact with the upper top plate 207, the limiting rod 102 has been completely separated from the limit rod 216, and the roller 217 has been in contact with the side of the metal plate.

[0031] like Figure 4-Figure 6As shown, the length and width mechanism includes a fixed seat 206 fixedly installed below the disc frame 201, the material of the lower surface of the disc frame 201 is copper, a top motor 202 is fixedly installed on the disc frame 201, a motor gear 203 is fixedly installed on the motor shaft of the top motor 202, a gear shaft 211 is rotatably installed on the disc frame 201, an upper gear 204 and a lower gear 212 are fixedly installed on the gear shaft 211, the motor gear 203 is meshed with the upper gear 204, a rotating frame 209 is rotatably installed outside the fixed seat 206, a central gear 210 is fixedly installed on the rotating frame 209, and a central gear 210 is fixedly installed on the central gear 210. The gear 210 is meshed with the lower gear 212, and two inner slide bars 213 are slidably installed in the rotating frame 209, and an inward spring 214 is arranged between the inner slide bar 213 and the rotating frame 209. A capacitor needle 215 is fixedly installed on the inner slide bar 213, and the capacitor needle 215 contacts the lower surface of the disc frame 201. A roller 217 is rotatably installed on the inner slide bar 213, and a limit rod 216 is rotatably installed on the inner slide bar 213. Contact blocks 218 are rotatably installed on the two limit rods 216, and the contact blocks 218 contact the limit rod 102. In the initial state, the inward spring 214 is in a stretched state.

[0032] like Figure 4-Figure 6 As shown, a thickness measuring column 205 is slidably installed in the fixed seat 206, an upper top plate 207 is fixedly installed below the thickness measuring column 205, a lifting spring 208 is arranged between the upper top plate 207 and the fixed seat 206, and a distance sensor is arranged on the top of the thickness measuring column 205.

[0033] As the limiting rod 102 moves outward, the limiting rod 102 will move away from the contact block 218. At this time, the retraction spring 214 gradually rebounds, causing the inner slide bar 213, the roller 217 and the capacitor needle 215 to move inward. When the roller 217 contacts the side of the metal plate, the retraction spring 214 no longer rebounds, but still has elastic force. When the upper top block 106 rises to the highest point, the bottom electric cylinder 103 stops for a short period of time, and the top motor 202 controls the motor gear 203 to rotate, thereby driving the upper gear 204, the gear shaft 211 and the lower gear 212 to rotate, thereby driving the central gear 210 and the rotating frame 209 to rotate. Under the action of the retraction spring 214, the inner slide bar 213 and the retraction spring 214 slide, and the roller 217 is driven to circle around the outer wall of the metal plate, and a pattern is formed through the capacitor needle 215 and the lower surface of the disc frame 201, and transmitted to the controller to obtain the length and width of the metal plate.

[0034] like Figure 7-Figure 9 As shown, the conveying mechanism includes a plurality of feeding friction wheels 311 rotatably mounted in the placement box 101 , and two feeding friction wheels 312 rotatably mounted on the detection box 113 .

[0035] like Figure 7-Figure 9As shown, a bottom motor 301 is fixedly installed at the bottom of the detection box 113, and a bottom gear 302 is fixedly installed on the motor shaft of the bottom motor 301. A lower docking gear 303 is rotatably installed at the bottom of the detection box 113, and an inner docking gear 304 is fixedly installed on the lower docking gear 303. The bottom gear 302 meshes with the lower docking gear 303. A sliding seat 309 is slidably installed at the bottom of the detection box 113, and a sliding seat spring 310 is arranged between the sliding seat 309 and the detection box 113. A driving wheel 306 and two driven wheels 307 are rotatably installed on the sliding seat 309, and a driving gear 305 is fixedly installed on the driving wheel 306. The driving gear 305 meshes with the inner docking gear 304. The driving wheel 306 and the two driven wheels 307 are wrapped with a friction belt 308. In the initial state, the friction belt 308 forms a friction transmission with a feeding friction wheel 311 on the side closest to the detection box 113, and the friction belt 308 forms a friction transmission with a sending friction wheel 312.

[0036] like Figure 7-Figure 9 As shown, an outlet plate 314 is slidably installed on the detection box 113, a friction strip 315 and an opening are provided on the outlet plate 314, a spring is provided between the outlet plate 314 and the detection box 113, a switch plate 313 is rotatably installed on the placement box 101, and a torsion spring 316 is provided between the switch plate 313 and the placement box 101.

[0037] When in use, metal sheets are stacked in the placement box 101, and the bottom motor 301 controls the bottom gear 302 to rotate. The bottom gear 302 drives the lower docking gear 303 and the inner docking gear 304 to rotate, thereby driving the driving gear 305 and the driving wheel 306 to rotate, thereby driving the friction belt 308 to rotate. The friction belt 308 drives the feeding friction wheel 311 and the delivery friction wheel 312 on the side closest to the detection box 113 to rotate through friction transmission, and the metal sheet of the bottom layer is transported toward the detection box 113 through the feeding friction wheel 311. The metal sheet pushes the switch plate 313, so that the switch plate 313 rotates relative to the placement box 101, and the torsion spring 316 is twisted. When the metal sheet is transported to contact with the outlet plate 314, the bottom motor 301 stops rotating, and the bottom electric cylinder 103 begins to extend.

[0038] When the metal sheet measurement is completed, the bottom electric cylinder 103 continues to extend, so that the lifting block 105 reaches the rear of the upper lifting block 106. At this time, the metal sheet and the upper lifting block 106 fall under the action of gravity, and the metal sheet falls back into the detection box 113. The extended push block 104 continues to move forward and contacts the sliding seat 309, pushing the sliding seat 309 to slide along the detection box 113. The sliding seat spring 310 is compressed, so that the friction belt 308 is separated from the feeding friction wheel 311, and the friction belt 308 only forms a friction transmission with the feeding friction wheel 312. When the bottom electric cylinder 103 is extended to the farthest, the extended push block 104 pushes the sliding seat 309 to the limit position. At this time, the friction belt 308 contacts the friction strip 315 to form a friction transmission. At this time, the bottom electric cylinder 103 stops, and the bottom motor 301 starts to rotate. The rotation of the friction belt 308 drives the friction strip 315 and the outlet plate 314 to rise, and the spring between the outlet plate 314 and the detection box 113 is compressed, so that the opening on the outlet plate 314 reaches the front of the detection box 113, and at the same time, the friction belt 308 drives the delivery friction wheel 312 to rotate, and the delivery friction wheel 312 delivers the metal sheet through the opening on the outlet plate 314 and out of the detection box 113, and the outlet plate 314 is reset under the rebound of the spring, and then the bottom motor 301 stops rotating, the bottom electric cylinder 103 is quickly retracted, and the limiting rod 102 pushes the contact block 218 again, so that the inner slide bar 213 extends to the farthest again, the retraction spring 214 is stretched and restored to the initial state, the sliding seat 309 is reset under the rebound of the sliding seat spring 310, and the friction belt 308 resumes contact with the feeding friction wheel 311.

[0039] The working principle of a continuous measuring device for the external dimensions of metal plates disclosed in the present invention is as follows: when in use, metal plates are stacked in a placement box 101, and a bottom motor 301 controls the bottom gear 302 to rotate, and the bottom gear 302 drives the lower docking gear 303 and the inner docking gear 304 to rotate, thereby driving the driving gear 305 and the driving wheel 306 to rotate, thereby driving the friction belt 308 to rotate, and the friction belt 308 drives the feeding friction wheel 311 and the sending friction wheel 312 on the side closest to the detection box 113 to rotate through friction transmission, and the metal plates of the bottom layer are transported toward the detection box 113 through the feeding friction wheel 311, and the metal plates push the switch plate 313, so that the switch plate 313 rotates relative to the placement box 101, and the torsion spring 316 is twisted. When the metal plates are transported to contact with the outlet plate 314, the bottom motor 301 stops rotating, and at this time the bottom electric cylinder 103 begins to extend. When the metal sheet is conveyed to the detection box 113, the bottom motor 301 stops rotating, the bottom electric cylinder 103 extends, driving the extended push block 104 to slide along the placement box 101, thereby driving the lifting block 105 to move, and the lifting block 105 lifts the upper top block 106, so that the upper top block 106 lifts the metal sheet in the detection box 113. When there is no metal sheet in the detection box 113, when the upper top block 106 is lifted to the highest point, the upper surface of the upper top block 106 just contacts the lower surface of the upper top plate 207. When the upper top block 106 lifts the metal sheet, due to the thickness of the metal sheet, the metal sheet will push the upper top plate 207 upward, and the lifting spring 208 is The thickness measuring column 205 is compressed. At this time, the thickness measuring column 205 rises. The rising distance of the thickness measuring column 205 is the thickness of the metal plate, which is measured by the distance sensor on the top of the thickness measuring column 205. When the push block 104 is extended and moved, the docking gear 108 is driven to rotate through the upper rack 107, and the upper acceleration gear 109 and the lower acceleration gear 110 are accelerated to drive the lower rack 111, the retreat frame 112 and the limiting rod 102 to slide outward, so that the stroke of the limiting rod 102 is greater than the stroke of the extended push block 104, so that when the metal plate rises to contact with the upper top plate 207, the limiting rod 102 has been completely separated from the limit rod 216, and the roller 217 has been in contact with the side of the metal plate.As the limiting rod 102 moves outward, the limiting rod 102 will move away from the contact block 218. At this time, the retraction spring 214 gradually rebounds, causing the inner slide bar 213, the roller 217 and the capacitor needle 215 to move inward. When the roller 217 contacts the side of the metal plate, the retraction spring 214 no longer rebounds, but still has elastic force. When the upper top block 106 rises to the highest point, the bottom electric cylinder 103 stops for a short period of time, and the top motor 202 controls the motor gear 203 to rotate, thereby driving the upper gear 204, the gear shaft 211 and the lower gear 212 to rotate, thereby driving the central gear 210 and the rotating frame 209 to rotate. Under the action of the retraction spring 214, the inner slide bar 213 and the retraction spring 214 slide, and the roller 217 is driven to circle around the outer wall of the metal plate, and a pattern is formed through the capacitor needle 215 and the lower surface of the disc frame 201, and transmitted to the controller to obtain the length and width of the metal plate. When the metal sheet measurement is completed, the bottom electric cylinder 103 continues to extend, so that the lifting block 105 reaches the rear of the upper lifting block 106. At this time, the metal sheet and the upper lifting block 106 fall under the action of gravity, and the metal sheet falls back into the detection box 113. The extended push block 104 continues to move forward and contacts the sliding seat 309, pushing the sliding seat 309 to slide along the detection box 113. The sliding seat spring 310 is compressed, so that the friction belt 308 is separated from the feeding friction wheel 311, and the friction belt 308 only forms a friction transmission with the feeding friction wheel 312. When the bottom electric cylinder 103 is extended to the farthest, the extended push block 104 pushes the sliding seat 309 to the limit position. At this time, the friction belt 308 contacts the friction strip 315 to form a friction transmission. At this time, the bottom electric cylinder 103 stops, and the bottom motor 301 starts to rotate. The rotation of the friction belt 308 drives the friction strip 315 and the outlet plate 314 to rise, and the spring between the outlet plate 314 and the detection box 113 is compressed, so that the opening on the outlet plate 314 reaches the front of the detection box 113, and at the same time, the friction belt 308 drives the delivery friction wheel 312 to rotate, and the delivery friction wheel 312 delivers the metal sheet through the opening on the outlet plate 314 and out of the detection box 113, and the outlet plate 314 is reset under the rebound of the spring, and then the bottom motor 301 stops rotating, the bottom electric cylinder 103 is quickly retracted, and the limiting rod 102 pushes the contact block 218 again, so that the inner slide bar 213 extends to the farthest again, the retraction spring 214 is stretched and restored to the initial state, the sliding seat 309 is reset under the rebound of the sliding seat spring 310, and the friction belt 308 resumes contact with the feeding friction wheel 311.
