[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1-Figure 9The present invention provides a technical solution: a flattening device for metal tableware, comprising: a workbench 1, an infrared sensor is installed at the middle of the workbench 1 corresponding to the edge of the workpiece and at the end of the workbench 1 for detecting the position of the fixed plate 26, a pressing plate 6 is provided on the top of the workbench 1 for flattening the workpiece, a lower cleaning brush 42 is fixedly connected to one side of the workbench 1, and the bristles of the lower cleaning brush 42 face upwards, and are used to clean the bottom of the workpiece sliding over the top thereof; a material storage part is placed on one side of the workbench 1, and the material storage part comprises a material discharging rack 9 with a material limiting rod arranged around it and a servo electric cylinder 8 fixedly connected to the bottom of the material discharging rack 9, a pushing plate is arranged on the top of the servo electric cylinder 8, and a through hole for the pushing plate to move is opened in the middle of the material discharging rack 9, and is used to lift the workpieces in the material discharging rack 9 upward one by one; a loading assembly is placed on the material discharging rack 9 The loading assembly includes a guide rail frame 11, a support plate 13 is horizontally slidably arranged above the guide rail frame 11, a sliding portion for driving the support plate 13 is fixedly connected to one side of the guide rail frame 11, a vacuum suction cup 17 is lifted and lowered in the middle of the support plate 13, a fixed plate 26 is fixedly connected to the end of the support plate 13, an upper scraper 24 and a lower scraper 25 are slidably connected to the outer side of the fixed plate 26, and a driving portion is fixedly connected to the top of the support plate 13, which is used to drive the upper scraper 24 and the lower scraper 25 to retract while driving the vacuum suction cup 17 to rise; when the support plate 13 moves laterally, the lower scraper 25 pushes the unloading while loading the material through the vacuum suction cup 17, and the upper scraper 24 and the lower scraper 25 unload the material while cleaning the extrusion plate 6 and the workbench 1, and when the upper scraper 24 and the lower scraper 25 retract, the lower scraper 25 cleans the workpiece that has just been loaded.

[0030] It should be noted that the present invention is provided with a controller and a corresponding operation panel, and the workpieces loaded with stainless steel discs are stacked inside the unloading rack 9 so that the top stainless steel disc corresponds to the vacuum suction cup 17. When started, the servo electric cylinder 8 lifts the stacked stainless steel discs upward so that the top stainless steel disc contacts the vacuum suction cup 17. Under the action of the vacuum generator, the vacuum suction cup 17 adsorbs and fixes the stainless steel discs, and the sliding part drives the support plate 13 to move horizontally in the direction of the workbench 1. During this period, the bottom of the stainless steel disc rubs against the bristles of the lower cleaning brush 42, and the lower cleaning brush 42 cleans the bottom of the stainless steel disc. While the support plate 13 continues to move forward, the lower scraper 25 slides on the top of the workbench 1, and pushes the workpiece after the top of the workbench 1 is flattened forward, while the top of the workbench 1 is scraped and cleaned, and the upper scraper 24 Sliding friction is performed with the bottom of the extrusion plate 6, and the bottom of the extrusion plate 6 is cleaned by the upper scraper 24. Under the elastic force of the spring four 36, the upper scraper 24 and the lower scraper 25 are tightly attached to the contact surface to prevent impurities from adhering and affecting the flattening of the workpiece. When the stainless steel disc is pushed onto the conveying mechanism on one side of the workbench 1, the vacuum suction cup 17 conveys the workpiece to the top of the workbench 1. When the infrared sensor detects the position of the fixed plate 26, the controller controls the driving part to drive the upper scraper 24 and the lower scraper 25 to slide toward the middle of the fixed plate 26. Under the action of the linkage, the vacuum suction cup 17 moves downward and the controller controls the vacuum generator to stop working. The stainless steel disc falls on the top of the workbench 1 under the action of gravity. Under the action of the timer, the sliding part drives the fixed plate 26 to reset. When resetting, the upper cleaning brush 40 on the side of the lower scraper 25 cleans the top of the stainless steel disc.

[0031] like Figure 1 , 2 As shown in Figure 6, the four corners of the top of the workbench 1 are fixedly connected with guide rods 2, the top of the guide rods 2 is fixedly connected with a top plate 4, the lifting and pressing plate 3 is slidably connected to the guide rods 2, the top of the top plate 4 is fixedly connected with a hydraulic cylinder 5, the output end of the hydraulic cylinder 5 is fixedly connected to the lifting and pressing plate 3, and the extrusion plate 6 is fixedly connected to the bottom of the lifting and pressing plate 3.

[0032] It should be noted that, in the present invention, after the support plate 13 drives the fixed plate 26 to reset, the hydraulic cylinder 5 drives the lifting plate 3 to move downward along the guide rod 2, and the lifting plate 3 drives the extrusion plate 6 to flatten the workpiece.

[0033] like Figure 1 , 2As shown in , 3, the sliding part includes a linear module 14 fixedly connected to one side of the guide rail frame 11, a sliding frame 12 is fixedly connected to the movable slide of the linear module 14, the sliding frame 12 is slidably connected to the guide rail frame 11, the sliding frame 12 is fixedly connected to the support plate 13, one end of the guide rail frame 11 is fixedly connected to a support column, the middle part of the support column is slidably connected to a guide slide rod 15, and the end of the guide slide rod 15 is fixedly connected to the fixed plate 26.

[0034] It should be noted that, when the present invention drives the support plate 13 to move toward the top of the workbench 1, the linear module 14 drives the sliding frame 12 to slide on the outside of the guide frame 11, the sliding frame 12 drives the support plate 13 to move on the workbench 1, the support plate 13 drives the fixed plate 26 to move between the workbench 1 and the unloading rack 9, and when the fixed plate 26 moves, it drives the guide slide rod 15 to slide in the middle of the support column, and the support column is fixedly connected to one end of the guide frame 11 close to the workbench 1, so as to ensure that the lifting frame 16 can move more stably above the workbench 1.

[0035] like Figure 1 , 2 As shown in Figures 3, 5 and 7, the fixed plate 26 is fixedly connected to the side away from the support plate 13 with a double-axis cylinder 28, and the output end of the double-axis cylinder 28 is fixedly connected to a connecting frame 34, and a rectangular slide bar 31 is slidably connected to the middle of the connecting frame 34, and a roller 29 is fixedly connected to the bottom of the rectangular slide bar 31 for detecting the thickness of the workpiece and pressing and cleaning the workpiece, and a sliding pressure plate 32 is slidably sleeved on the outer side of the rectangular slide bar 31 and located below the connecting frame 34, and a spring 30 is sleeved on the outer side of the rectangular slide bar 31 and located between the sliding pressure plate 32 and the roller 29, and a pressure sensor 33 is fixedly connected to the top of the sliding pressure plate 32 for detecting the thickness of the workpiece.

[0036] It should be noted that when the fixing plate 26 of the present invention moves to the side of the workpiece after being flattened, the infrared sensor detects the position of the fixing plate 26, and the infrared sensor transmits a signal to the controller. The controller controls the double-axis cylinder 28 to extend, and the double-axis cylinder 28 drives the connecting frame 34 to move downward. The connecting frame 34 drives the bottom of the second roller 29 to be placed on the top of the stainless steel disc. The second roller 29 drives the rectangular slide bar 31 and the spring three 30 to move upward under the reaction force. The spring three 30 drives the sliding pressure plate 32 to move upward, and the sliding pressure plate 32 drives the pressure sensor 33 to connect with the bottom of the connecting frame 34. The touch screen judges whether the thickness is within the preset range according to the values ​​of the two pressure sensors 33 corresponding to the two rollers 29. When the thickness of the workpiece is too large, the corresponding value of the pressure sensor 33 is too large. When the thickness of the workpiece is too small, the corresponding value of the pressure sensor 33 is too small. The sound and light alarm is used to warn unqualified workpieces. When the fixed plate 26 is reset, the dual-axis cylinder 28 drives the roller 29 to roll on the top of the workpiece. The downward pressure applied by the spring 30 increases the friction between the workpiece to be processed and the workbench 1 to prevent the workpiece from shifting when the upper cleaning brush 40 cleans the top of the workpiece.

[0037] like Figure 1 , 2 As shown in , 3, 4, 5, 8, and 9, a lifting frame 16 is fixedly connected to the top of the vacuum suction cup 17, and the lifting frame 16 is slidably connected to the support plate 13. The outer side of the lifting frame 16 and the top and bottom of the support plate 13 are sleeved with springs 19. A limiting slide bar 20 is fixedly connected to the top of the support plate 13, and a tilting push rod 21 is slidably connected to the outer side of the limiting slide bar 20. The tilting push rod 21 is slidably connected to the support plate 13, and the tilting push rod 21 passes through the middle of the lifting frame 16. A single-axis cylinder 23 is fixedly connected to the top of the support plate 13, and an inclined plane frame 22 is fixedly connected to the output end of the single-axis cylinder 23. The inclined plane frame 22 is fixedly connected to the inclined push rod 21, and a slot for the inclined plane frame 22 to slide is provided in the middle of the support plate 13. A T-shaped plate 27 is fixedly connected to one side of the fixing plate 26 close to the supporting plate 13, the upper scraper 24 and the lower scraper 25 are both slidably connected to the T-shaped plate 27, the top and bottom of the supporting plate 13 are both fixedly connected to the limiting frame 18, the middle part of the limiting frame 18 is slidably connected to an extrusion rod 35 with an inclined structure, when the single-axis cylinder 23 drives the inclined frame 22 to slide, the inclined frame 22 squeezes and drives the extrusion rod 35 in the direction of the supporting plate 13, the upper scraper 24 and the lower scraper 25 are fixedly connected to the corresponding extrusion rod 35, the middle part of the extrusion rod 35 is slidably connected to the limiting rod 37, the limiting rod 37 is fixedly connected to the limiting frame 18, and a spring four 36 is sleeved on the outside of the limiting rod 37 and located between the extrusion rod 35 and the supporting plate 13.

[0038] It should be noted that, in the present invention, when the workpiece behind the platform is pushed down from the top of the workbench 1, the vacuum suction cup 17 is placed in the middle of the workbench 1 with the workpiece to be processed. When the support plate 13 drives the fixed plate 26 to reset, the piston rod of the uniaxial cylinder 23 is extended, and the uniaxial cylinder 23 drives the inclined plane frame 22 to move in the direction of the fixed plate 26. The inner wall of the inclined plane frame 22 is an isosceles trapezoidal structure. The inclined surface of the inner wall of the inclined plane frame 22 squeezes the extrusion rod 35, so that the extrusion rod 35 slides in the middle of the limit frame 18. At the same time, the extrusion rod 35 drives the upper scraper 24 and the lower scraper 25 to move in the direction of the support plate 13. The upper scraper 24 and the lower scraper 25 slide on the outside of the T-shaped plate 27. The upper scraper 24 and the lower scraper 25 are both provided with grooves for the sliding of the T-shaped plate 27, and the T-shaped plate 27 can In order to ensure that when the upper scraper 24 and the lower scraper 25 are scraping, when the spring four 36 squeezes the squeezing rod 35, no lateral displacement occurs. Under the action of the elastic force, the upper scraper 24 and the lower scraper 25 can be more closely connected to the contact surface. When the inclined frame 22 moves forward, the inclined frame 22 drives the inclined push rod 21 to move forward. The inclined push rod 21 slides on the outside of the limiting slide bar 20, and the inclined surface of the inclined push rod 21 applies an upward force to the lifting frame 16, so that the lifting frame 16 compresses the spring two 19 at the top of the vacuum suction cup 17 and drives the vacuum suction cup 17 to move upward, so that the vacuum suction cup 17 is separated from the workpiece, preventing the vacuum suction cup 17 from contacting the workpiece during resetting, and avoiding displacement of the workpiece, thereby realizing that the vacuum suction cup 17 moves downward while the upper scraper 24 and the lower scraper 25 retract.

[0039] like Figure 4 , 9 As shown, the bottom of the limit frame 18 located below the support plate 13 is fixedly connected to a push rod 38, the bottom of the push rod 38 is fixedly connected to an upper cleaning brush 40, and a roller 7 is provided on one side of the upper cleaning brush 40 to slide up and down through a metal plate, and a spring 10 is installed at the top of the roller 7 and below the metal plate.

[0040] It should be noted that, in the present invention, when the lower scraper 25 moves upward, the upper cleaning brush 40 is in place under the action of the push rod 38, and the bristles of the upper cleaning brush 40 are in contact with the top of the workpiece. Two rollers 7 are provided, and the tops of the two rollers 7 and the bottom of the metal plate are fixedly connected with electromagnets. The magnetic poles of the two electromagnets are opposite when energized. When the fixed plate 26 moves to the edge of the workpiece to be processed during resetting, the electromagnet is energized under the action of the infrared sensor. Under the action of suction, the roller 7 compresses the spring 10 upward. At the same time, the connecting frame 34 of the double-axis cylinder 28 causes the roller 29 to move downward. Under the action of the timer, the electromagnet is de-energized, and the roller 7 is pressed on the workpiece to be processed under the action of the spring 10 and rolls on the workpiece to be processed. In addition, the internal lifting of the workbench 1 is provided with two metal rods for limiting the position of the workpiece, and the metal rods are located close to the guide rail frame. On one side of 11, the workbench 1 is provided with a hole that cooperates with the metal rod, which has a structure similar to that of a mold ejector. An electric telescopic rod is provided at the bottom of the metal rod for driving the metal rod to rise and fall. When loading, the top of the upper cleaning brush 40 is recovered into the workbench 1, and its top is flush with the top of the workbench 1. The support plate 13 drives the fixed plate 26 to reciprocate, and the electric telescopic rod drives the metal rod to rise. The top of the metal rod is lower than the height of the top of the workpiece, and the workpiece is blocked from the end by two metal rods to prevent the workpiece from being displaced when the upper cleaning brush 40 cooperates with it. The upper cleaning brush 40 cleans the surface of the workpiece to be processed. When the roller two 29 moves to the surface of the workpiece, the spring three 30 cooperates with the sliding pressure plate 32 and the pressure sensor 33 to detect the thickness of the workpiece to be processed after cleaning. When the vacuum suction cup 17 moves to the top of the discharge rack 9, under the action of the travel switch, the double-axis cylinder 28 and the single-axis cylinder 23 are reset.
