DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0034] like Figure 1-3 As shown, the present invention provides a follow-up automatic flipping mechanism, including a bracket 1, which is fixedly connected to a cutting machine 12, and a lifting device 2 and a turning device 3 are provided on the bracket 1; the lifting device 2 is fixedly connected to the bracket 1, and the lifting output end of the lifting device 2 is fixedly connected to the turning device 3; a plate fixing device 4 is fixedly connected to the turning device 3, and the plate fixing device 4 is located in the processing movement direction of the cutting machine 12; during use of the flipping mechanism, the plate 17 is first clamped and fixed by the plate fixing device 4, and then the lifting device 2 drives the turning device 3 to lift the plate 17 upward to a certain height, and then the turning device 3 drives the plate fixing device 4 to turn the plate 17, thereby completing the automatic flipping action; the various driving devices on the flipping mechanism are evenly distributed on the bracket 1 through the adoption of reasonable structural design and installation position layout, which greatly reduces the installation and use space and is convenient for use.

[0035] Furthermore, the lifting device 2 includes two groups of first-level fixed seats 21, and the two groups of first-level fixed seats 21 are respectively located on both sides of the bracket 1, and the bottom ends of the two groups of first-level fixed seats 21 are fixedly connected to the first-level cylinder 22, and the cylinder rods of the two groups of first-level cylinders 22 extend through the top of the first-level fixed seat 21 and are fixedly connected to the movable plate 23, and the two groups of movable plates 23 are fixedly connected to the flipping device 3 on the side away from the remaining bracket 1; when it is necessary to lift the plate 17 to the set position for flipping, start the first-level cylinder 22, so that the cylinder rod of the first-level cylinder 22 extends and drives the movable plate 23 to move upward, which can drive the flipping device to lift the plate 17 to a certain height, thereby realizing the lifting action of the plate 17; after the flipping is completed, control the first-level cylinder 22 to retract, and the plate 17 can be placed back on the table of the cutting machine 12.

[0036] Furthermore, the flipping device 3 includes a vertical plate 31, one side of the vertical plate 31 is fixedly connected to the two groups of movable plates 23, and the plate fixing device 4 is fixedly arranged on the other side of the vertical plate 31; the bottom of the vertical plate 31 and the side close to the bracket 1 is vertically fixedly connected to the slide plate 32, the bottom end of the slide plate 32 and the side away from the vertical plate 31 is fixedly connected to the motor frame 33, and the side of the motor frame 33 away from the vertical plate 31 is fixedly connected to the reducer 35, and the input end of the reducer 35 is installed with a servo motor 34, and the output shaft of the reducer 35 passes through and extends from the front end of the motor frame 33 and is fixedly connected to the rotating shaft 36, and the other end of the rotating shaft 36 passes through and extends from the front end of the vertical plate 31 and is fixedly connected to the plate fixing device 4; when the plate 17 is lifted to the set position, the servo motor 34 is started, and the rotating shaft 36 is driven to rotate after being decelerated by the reducer 35, thereby driving the plate fixing device 4 to rotate, thereby completing the top flipping action.

[0037] Furthermore, the plate fixing device 4 is a slot-shaped structure, and the slot opening is facing the processing movement direction of the cutting machine 12, so as to facilitate clamping and fixing the plate 17.

[0038] Furthermore, the plate fixing device 4 includes a supporting plate 41, the back of the supporting plate 41 is fixedly connected to the rotating shaft 36, the upper and lower ends of the supporting plate 41 are respectively fixedly connected to the limiting plates 42, and the left and right sides of the supporting plate 41 are respectively provided with side plates 43, and the two limiting plates 42 are fixedly connected to the opposite sides and near their two ends with electric push rods 44, the output end of the electric push rod 44 is fixedly connected to the side plate 43, and the electric push rods 44 are electrically connected to the control device.

[0039] Among them, the size of the plate fixing device 4 can be adjusted according to the width of the plate 17, so as to clamp plates 17 of different widths to enhance the applicability of the flipping mechanism; when the plate 17 needs to be clamped and fixed, the four sets of electric push rods 44 are first controlled by the control device to extend at the same time, and the two sets of side plates 43 are moved to the two sides of the plate 17 respectively, and then the gantry is used to drive the flipping mechanism to move to the side close to the plate 17, so that one end of the plate 17 is inserted between the two sets of limit plates 42 and close to the supporting plate 41, and then the four sets of electric push rods 44 are controlled to be retracted at the same time, thereby driving the two sets of side plates 43 to adjust the plate 17 to the center, so that when the plate 17 is subsequently flipped, the rotation space on the upper and lower sides of the plate 17 is the same, the working space can be effectively utilized, and the working area occupied by the flipping mechanism is reduced; at the same time, it can avoid the radial tension of the rotating shaft 36 increasing due to the different weights on both sides of the plate 17 during the flipping process, thereby reducing the wear on the surface of the rotating shaft 36.

[0040] Furthermore, it also includes a grasping device 5; the grasping device 5 includes two groups of secondary fixing seats 51, and the two groups of secondary fixing seats 51 are respectively located on the same side of the bracket 1 as the primary fixing seat 21, and the top ends of the two groups of secondary fixing seats 51 are fixedly connected to the secondary cylinder 52, and the cylinder rod of the secondary cylinder 52 extends through the bottom end of the secondary fixing seat 51 and is fixedly connected to a vacuum generator 53, and the vacuum port of the vacuum generator 53 is fixedly connected to a suction cup 54 vertically downward, and the nozzle air inlet of the vacuum generator 53 is connected to an air compressor through a pipeline, and the air compressor is electrically connected to the control device.

[0041] Among them, when one side of the plate 17 is processed with holes and grooves, the flip mechanism can be moved to the set position by the gantry on the cutting machine 12, and then the cylinder rod of the secondary cylinder 52 is controlled to extend, driving the vacuum generator 53 and the suction cup 54 to move downward, so that the suction cup 54 is at the top of the plate 17; at the same time, the vacuum generator 53 is opened, and the suction cup 54 is adsorbed on the plate 17 due to the negative pressure generated by the internal vacuum, which can firmly suck the plate 17; then the secondary cylinder 52 is retracted, and the suction cup 54 maintains a negative pressure state; the gantry drives the flip mechanism to move to the rear side of the cutting machine 12 and stops after reaching the specified position; then, the secondary cylinder 52 continues to extend, placing the plate 17 on the bed of the cutting machine 12, and then the air compressor is controlled to stop, so that the vacuum generator 53 is turned off, releasing the vacuum, and then the suction cup 54 loosens the plate 17, thereby completing the automatic grabbing, moving and unloading actions of the plate 17.

[0042] Furthermore, since the retraction direction of the cylinder rod of the first-stage cylinder 22 is vertically downward, which coincides with the gravity direction of the load, the first-stage cylinder 22 generates a certain inertial force downward during the retraction process; therefore, a buffer pad 9 of the same size as the first-stage fixed seat 21 can be installed on the top of the first-stage fixed seat 21, which can play a certain buffering role on the movable plate 23, avoiding the movable plate 23 from colliding with the first-stage fixed seat 21 under the action of inertia force during the downward movement, causing the internal components of the mechanism to become loose.

[0043] Furthermore, in order to enhance the bearing capacity of the slide plate 32 , triangular plate-type reinforcing ribs 8 are vertically fixedly installed at both ends of the side walls of the slide plate 32 , and the reinforcing ribs 8 are vertically fixedly installed on the vertical plate 31 .

[0044] Furthermore, both ends of the rotating shaft 36 are connected to the bottom end of the slide 32 through the first bearing seat 6 and the second bearing seat 7 respectively; this is convenient for ensuring that the rotating shaft 36 is coaxial with the output shaft of the servo motor 34 during the driving process of the servo motor 34.

[0045] Furthermore, the bracket 1 includes two groups of U-shaped frames 101, and the two groups of U-shaped frames 101 are symmetrically distributed in the vertical direction, and the top ends of the opposite surfaces of the two groups of U-shaped frames 101 are vertically symmetrically fixedly connected with two groups of cross beams 102; the opposite sides of one group of U-shaped frames 101 are respectively fixedly connected to the opposite surfaces of the two groups of primary fixing seats 21; the bottom ends of the two groups of U-shaped frames 101 are symmetrically fixedly connected with two groups of mounting frames 103, and the two groups of mounting frames 103 are respectively arranged parallel to the two groups of cross beams 102; the ends of the two groups of mounting frames 103 away from the vertical plates 31 extend to the outside of the bracket 1 and are fixedly connected with mounting seats 104, and multiple groups of mounting holes 1041 are evenly provided on the mounting seats 104; the sides of the two groups of mounting frames 103 away from each other are respectively fixedly connected to the opposite surfaces of the two groups of secondary fixing seats 51, and the two groups of secondary fixing seats 51 are both located between the two groups of U-shaped frames 101; the bracket 1 can be fixedly installed on the gantry by passing fasteners such as bolts and nuts through the mounting holes 1041, which is convenient for later disassembly and maintenance.

[0046] In the above, the follower-type flipping mechanism can move with the gantry of the cutting machine 12, and can realize the grabbing and flipping functions of rulers, rulers and ruler-sized plates; compared with the previous bed-fixed flipping mechanism, it breaks the length limit of the plate 17.

[0047] In this embodiment, in order to enhance the stability of the vertical plate 31 during the up and down movement, two sets of slide rails 11 are symmetrically arranged between the vertical plate 31 and the bracket 1 in the vertical direction. The two sets of slide rails 11 are fixedly connected to the vertical plate 31, and the two sets of slide rails 11 are located on both sides of the slide plate 32; during the assembly process, the slide rails 11 are conveniently matched with the protective cover 10 installed on the top of the cutting machine 12, so that the slide rails 11 are slidably connected with the slide groove arranged inside it; and, by installing the flip mechanism inside the protective cover 10, the flip mechanism can avoid the operator from being hit or pinched during operation, which can reduce certain safety hazards.

[0048] As an embodiment of the present invention, reference Figure 4As shown, two sets of flipping mechanisms can be set on the cutting machine 12 for use to realize the automated production and processing of the plate 17; first, a first processing station 121 and a second processing station 122 are respectively set at the front end and the rear end of the cutting machine 12 bed, and then a first flipping mechanism 15 is installed at the first processing station 121 through a first-level gantry 13, and a second flipping mechanism 16 is installed at the second processing station 122 through a second-level gantry 14, and the openings of the plate fixing devices 4 on the first flipping mechanism 15 and the second flipping mechanism 16 are both facing one side of the cutting machine 12 bed; after the holes and grooves on one side of the plate 17 are processed at the first processing station 121, the first flipping mechanism 15 can be used to fix the plate 17 on the second processing station 122. The gripping device 5 in the mechanism 15 absorbs and grips the plate 17, and then drives the first flip mechanism 15 through the first-level gantry 13 to move the plate 17 to the bed at the rear side of the cutting machine 12, and then releases the plate 17 through the gripping device 5; then the first flip mechanism 15 is driven by the first-level gantry 13 to move toward the front side of the cutting machine 12, so that the plate 17 is located between the first flip mechanism 15 and the second flip mechanism 16; then, the plate 17 is lifted upward by the jacking cylinder 123 on the bed, so that the height of the plate fixing devices 4 on the left and right sides of the plate 17 is the same as the height at which the plate 17 is lifted, and then the first-level gantry 13 and the second-level gantry 14 are respectively driven to lift the plate 17 upward. The first flap mechanism 15 and the second flap mechanism 16 are driven to move to the side close to the plate 17, and the plate 17 is clamped in the two sets of plate fixing devices 4, and then the first-level cylinder 22 provided in the first flap mechanism 15 and the second flap mechanism 16 are synchronously extended to lift the plate 17 upward to the set height; then the two sets of servo motors 34 are synchronously driven to rotate the two sets of rotating grooves 180 degrees to the same side of the cutting machine 12 to complete the top flap action; then the first-level cylinder 22 is controlled to retract to drop the plate 17 back to the table, and then the first flap mechanism 15 and the second flap mechanism 16 are controlled to return to the original state; finally, the second flap mechanism 16 is driven to move to the plate 17 through the secondary gantry 14 7, and then the plate 17 is sucked and grabbed by the grasping device 5 on the second flip mechanism 16, and then the second flip mechanism 16 is driven by the secondary gantry 14 to move the plate 17 to the second processing station 122 of the cutting machine 12, and then the second flip mechanism 16 is controlled to return to the origin, and the plate 17 can be processed on the next side; thereby, an automated production line can be formed to realize the front processing, flipping and back processing of the plate 17, which can shorten the flip preparation cycle and improve the production and processing efficiency; and, the various driving devices on the flip mechanism are evenly distributed on the bracket 1 through the adoption of reasonable structural design and installation position layout, which greatly reduces the installation and use space.
