The processing flow of the plate includes: first cutting according to the size with a cutting equipment, then stacking the cut plates through a material cart, and then transporting them to the bending machine after stacking. The operator bends the plates one by one. Because the plates are stacked, the thickness of the plates is thin, and the edges of the plates are not easy to pick up, which affects the working efficiency. Summary of the invention

The first pallet can move between directly above the lifting frame and the loading station. The transport unit is used to transport the plate above the first pallet to the unloading station.

[0005] Furthermore, the material picking assembly also includes a pressing member arranged above the lifting frame and a first elastic member arranged above the pressing member, the first elastic member can provide a vertical downward elastic force to the pressing member, a plurality of first suction cups are symmetrically arranged on both sides of the pressing member, and the lower end of the pressing member is located below the first suction cup.

[0006] Furthermore, a connecting plate seat is arranged above the pressing member, a second rigid rod is arranged vertically on the connecting plate seat, and the pressing member is arranged at the end of the second rigid rod.

[0007] Furthermore, the first elastic member is a second compression spring sleeved on the second rigid rod.

[0008] Furthermore, a displacement sensor is provided between the connecting plate seat and the pressing member.

[0009] Furthermore, arm plates are movably arranged on both sides of the connecting plate seat along a horizontal direction perpendicular to the movement of the first supporting plate, and the first suction cup is arranged on the arm plates.

[0010] Furthermore, a second elastic member is disposed between the two arm plates and the connecting plate seat, and the two second elastic members have opposite elastic directions and equal elastic forces on the connecting plate seat.

[0011] Furthermore, two first guide rails are arranged in parallel and at intervals on the connecting plate seat, and the two arm plates are slidingly matched with the first guide rails.

[0012] Furthermore, the transport unit comprises two second guide rails arranged at intervals, a first movable frame slidably guided on the two second guide rails, and at least two suction cup assemblies arranged at intervals on the first movable frame.

[0013] Furthermore, the suction cup assembly includes a second movable frame slidably arranged on the first movable frame, a power telescopic member vertically arranged on the second movable frame, and a second suction cup arranged at the lower end of the power telescopic member.

[0014] The metal plate bending and shaping device disclosed in the present invention has the following beneficial effects compared with the prior art: 1. The present application sets up a material picking unit, which includes a material picking assembly, a first frame, and a transport unit that cooperate with each other. The material picking assembly sucks metal plates one by one through a lifting frame and a second suction cup arranged above the lifting frame.

The transport unit transports the plate above the first pallet to the bending machine, assists in the bending material handling work, and improves the efficiency of the bending operation.

[0015] 2. By arranging a pressing component between the first suction cups of the material picking component, the pressing part of the pressing component can apply a downward bending force to the first suction cup to bend it. When a metal plate is adsorbed under the adsorbed metal plate, the uppermost metal plate is bent, which is conducive to generating a gap between adjacent metal plates, and is conducive to rapid replenishment of external air between adjacent metal plates, so that the two metal plates are separated, thereby facilitating the separation of the two adjacent plates.

[0038] As a specific implementation, the present application provides a metal plate 5 bending and shaping device comprising: a bending machine 1, the bending machine 1 uses a commonly used device in the prior art, which is not an improvement point of the present application, and its specific structure is not described here. Figure 1 The bending machine 1 includes a movable bracket 10. When in use, the movable bracket 10 is used to lift the metal plate 5 to be bent, wherein the unloading station of the handling device is located directly above the movable bracket 10. Figure 2-Figure 5 The first frame 2 includes a first support frame 20 arranged on the ground, wherein the loading station is located directly above the first support frame 20.

[0039] refer to Figure 2-Figure 5 , two guide rods 22 are arranged on the first support frame 20 at intervals, and a first lead screw 23 is arranged between the two guide rods 22, a sliding member 220 is arranged on the guide rod 22 for guiding sliding, the first lead screw is threadedly connected with a first lead screw nut 230, the first support plate 21 includes a plate member of the frame 210 arranged on the upper surface of the frame 210, the first lead screw nut and the sliding member 220 are connected to the lower surface of the frame 210, refer to Figure 4 When the sliding member 220 is at the end of the guide rod 22 close to the bending machine 1, the first support plate 21 is directly above the first support frame 20. At the end of the first support frame 20 away from the bending machine 1, a rolling member 25 is also provided. The axis of the rolling member 25 is perpendicular to the axis of the guide rod 22. The rolling member 25 is supported and rolled with the bottom surface of the frame 210. When the first screw is driven by the driving motor, it can drive the first screw nut to move, thereby driving the first support plate 21 to move in the horizontal direction.

[0040] refer to Figure 6 The material taking component 32 includes a vertically lifting and lowering frame 31 and a plurality of first suction cups 323 arranged above the lifting and lowering frame 31. Fig.16The specific driving mode and specific matching structure of the lifting frame 31 are as follows: it includes a support plate 315 spaced apart from the ground, four guide members 312 are arranged on the support plate 315, the lower end of the guide member 312 is connected to the first plate 311, and the upper end is connected to the lifting frame 31, and a second lead screw nut 314 is arranged in the middle area of ​​the first plate 311 to prevent axial movement, and the second lead screw nut 314 is connected to a vertically arranged second lead screw 313, the upper end of the second lead screw 313 is rotationally matched with the support plate 315, and the lower end is drivingly connected to a servo motor 310, and the purpose of driving the lifting frame 31 to move in the vertical direction is achieved by the rotation of the servo motor 310; as a further preferred method, two vertical rods 316 are also arranged on the first support frame 20, and a sliding seat 3160 is matched with a sliding guide on each vertical rod 316, and the sliding seat 3160 is connected to the lifting frame 31.

[0041] The working mode of a metal plate 5 bending and shaping device provided in the present application is as follows: Step 1: stack the metal plates 5 after unloading on the lifting frame 31, control the lifting frame 31 to lift and lower, so that the plate surface of the uppermost metal plate 5 is not higher than the upper surface of the first support plate 21, and adjust the height of the second suction cup 432, so that the vertical spacing distance between the lower surface of the second suction cup 432 and the upper surface of the first support plate 21 is between 10cm and 20cm, and obtain the initial distance between the second suction cup 432 and the first support plate 21; Step 2: Obtain the initial height of the lifting frame 31 and the distance between the uppermost metal plate 5 and the upper surface of the first support plate 21; Step 3, control the lifting frame 31 to rise, lift the metal plate 5, and stop lifting and keep it when the uppermost metal plate 5 contacts the lower surface of the second suction cup 432; Step 4: Control the first suction cup 323 to work and adsorb the metal plate 5, and then control the lifting frame 31 to lower, so that the upper surface of the uppermost metal plate 5 of the lifting frame 31 is lower than the lower surface of the first supporting plate 21; Step 5: The first support plate 21 moves horizontally to below the first suction cup 323, the first suction cup 323 stops working, the metal plate 5 is separated from the first suction cup 323 under the action of gravity, and the first support plate 21 lifts the metal plate 5; Step 6. The first pallet 21 moves horizontally to the loading station, and then the transport device at the loading station transports the metal plate 5 on the first pallet 21 to the unloading station, and places the metal plate 5 on the movable bracket 10 of the unloading station, thereby completing the transport of the plates one by one, assisting the bending machine 1 to complete the bending operation, and improving the operation efficiency.

[0042] Furthermore, in some preferred embodiments, the first support plate 21 may include a frame 210 and a plate body arranged on the frame 210, and a lifting frame 31 is vertically arranged between the plate body, the first support plate 21 and the frame 210, and the lifting frame 31 can drive the plate body to rise and fall in the vertical direction, so that when lifting the metal plate 5 adsorbed by the first suction cup 323, the lifting frame 31 is first controlled to be in a retracted state, at which time the upper surface of the plate body is lower than the metal plate 5 adsorbed on the first suction cup 323, and then it moves horizontally to below the first suction cup 323, and then the lifting frame 31 is controlled to drive the plate body to rise so that the plate body contacts the lower surface of the metal plate 5, and then the first suction cup 323 is controlled to release the metal plate 5, so that the metal plate 5 can be better lifted, and then the lifting frame 31 is controlled to fall, return to the retracted state, and move horizontally to the loading station.

[0043] Embodiment 2 It is understandable that when the metal plates 5 are stacked, since the surface finish of the metal plates 5 is very high, after the air between the adjacent plates is squeezed out when the plates are stacked, the plates are easily adsorbed due to negative pressure. Especially when processing carbon steel cold plates, the plates are coated with oil film on the surface, and the phenomenon of adsorption between adjacent plates is more frequent. When the plates are adsorbed, the material taking component 32 is easy to take and put two or more plates at a time. In order to reduce the occurrence of the above phenomenon, refer to Figure 6 , Figure 7 As a further improvement, the present application provides a metal plate 5 bending and shaping device, which is different from the first embodiment in that the material picking assembly 32 also includes a pressing piece 332 arranged above the lifting frame 31 and a first elastic piece arranged above the pressing piece 332, and the first elastic piece can provide a vertical downward elastic force to the pressing piece 332, and a plurality of first suction cups 323 are symmetrically arranged on both sides of the pressing piece 332, and the lower end of the pressing piece 332 is located below the first suction cup 323.

[0044] Specifically, refer to Figure 6 , Figure 7 , Fig.13 , Fig.17 The first suction cup 323 includes four parts, which are respectively arranged at both ends of the lifting frame 31. A pressing assembly 33 is arranged between the two groups of suction cups. The pressing assembly 33 includes a strip-shaped pressing member 332 and a first elastic member exerting force on the pressing member 332. The first elastic member provides a downward elastic force to the pressing member 332. In the initial state under the elastic force of the first elastic member, the lower end of the pressing member 332 is lower than the lower surface of the first suction cup 323. Fig.13The first suction cup 323 is hingedly connected by a ball joint 3233. With this arrangement, when the lifting frame 31 rises, the uppermost metal plate 5 contacts the pressing piece 332 first, and at this time, it continues to move against the elastic force of the first elastic member until the metal plate 5 contacts the lower surface of the first suction cup 323, and then the first suction cup 323 generates a negative pressure suction force to adsorb and fix the metal plate 5, and then the lifting frame 31 moves downward. During the downward movement of the lifting frame 31, the pressing piece 332 is pushed downward by the elastic force of the first elastic member, providing a downward thrust to the metal plate 5 adsorbed by the first suction cup 323. Fig.17 At this time, the metal plate 5 adsorbed by the first suction cup 323 can be bent, and the two ends of the metal plate 5 can be tilted upward. At this time, when there is a metal plate 5 adsorbed below the metal plate 5 adsorbed by the first suction cup 323, since the top metal plate 5 is bent, it is beneficial to generate a gap between adjacent metal plates 5, which is beneficial for external air to quickly replenish between adjacent metal plates 5, so as to separate the two metal plates 5, thereby facilitating the separation of the two adjacent plates.

[0045] Further, as a specific implementation, the specific structure of the pressing component 33 is: Fig.14 , Fig.15 , a connecting plate seat 330 is arranged above the pressing member 332, a second rigid rod 333 is arranged vertically on the connecting plate seat 330, and the pressing member 332 is arranged at the end of the second rigid rod 333. Specifically, the connecting plate seat 330 is arranged horizontally, and is located directly above the lifting frame 31. Along the movement direction of the first supporting plate 21, two second rigid rods 333 are arranged on the connecting plate seat 330 at intervals. The upper end of the second rigid rod 333 is threadedly connected to the limiting nut, and the lower end is connected to the strip-shaped pressing member 332. The first elastic member is two second compression springs 334 sleeved on the two second rigid rods 333. Under the elastic force of the second compression springs 334, the limiting nut is limited to the upper side of the connecting plate seat 330, and the second compression springs 334 are in a compressed state.

[0046] Furthermore, the first elastic member is a second compression spring 334 sleeved on the second rigid rod 333 .

[0047] Further, as a preferred embodiment, a displacement sensor 336 is provided between the connecting plate seat 330 and the pressing member 332. Fig.14, is the initial state of the pressing component 33. In the initial state, the displacement sensor 336 is the working zero point. At this time, the vertical distance between the lower end of the pressing piece 332 and the lower surface of the first suction cup 323 is known. When the lifting frame 31 is lifted or lowered, the uppermost metal plate 5 contacts the pressing piece 332 first and squeezes the second compression spring 334 to push the pressing piece 332 to rise. At this time, the displacement sensor 336 can obtain the movement displacement of the pressing piece 332, and the lifting of the lifting frame 31 can be controlled according to the displacement detected by the displacement sensor 336. When the uppermost metal plate 5 contacts the lower surface of the first suction cup 323, the lifting stops, thereby more accurately controlling the lifting of the lifting frame 31 and ensuring working reliability.

[0048] Further, as a specific implementation, arm plates 322 are movably provided on both sides of the connecting plate seat 330 along a horizontal direction perpendicular to the movement of the first support plate 21 , and the first suction cup 323 is provided on the arm plates 322 .

[0049] refer to Figure 6-Figure 11 , Fig.15 The upper surface of the connecting plate seat 330 is provided with two sets of guide sleeves 331, each set of guide sleeves 331 is provided with a first guide rail 34, the first guide rail 34 and the first guide sleeve 331 are locked by a locking screw, and both ends of the two first guide rails 34 are guided and slidably matched with arm plates 322, refer to Fig.12 , Fig.13 , two first rigid rods 3230 are provided on each arm plate 322, and the lower end of the first rigid rod 3230 is hingedly connected to the first suction cup 323 through a ball joint 3233. With this arrangement, the first suction cup 323 has a swing amount in the vertical direction, so as to adapt to the bending state of the adsorbed metal plate 5. Each arm plate 322 is vertically connected to three support rods 321, and the lower ends of the three support rods 321 are connected to a horizontal connecting beam 320, and the connecting beam 320 cooperates with the horizontal guiding of the support plate 315. With this arrangement, the position of the arm plate 322 can be slidably adjusted according to the size of the metal plate 5 to be bent in the length direction of the first guide rail 34, so as to adapt to metal plates 5 of different sizes.

[0050] As a preferred embodiment, refer to Fig.13It can be understood that when the first suction cup 323 adsorbs the metal plate 5 and the metal plate 5 bends under the pressing force of the pressing piece 332, the metal plate 5 will provide a force to the first suction cup 323 in the direction close to the pressing piece 332. The arm plate 322 of the present application includes two extending arms, each of which is provided with a first suction cup 323, wherein the extending arms include a first arm 3221 and a second arm 3223 which are guided and matched along a direction parallel to the first guide rail 34, the first suction cup 323 is provided at the end of the first arm 3221, the second arm 3223 is connected to the three support rods 321, a tension spring 3222 is provided between the first arm 3221 and the second arm 3223, and the first arm 3221 is pressed against the second arm 3223 under the tension of the tension spring 3222. Fig.13 The state shown is the initial state. When the metal plate 5 is adsorbed, the pressing piece 332 presses downward on the middle area of ​​the metal plate 5 under the elastic force of the second compression spring 334. At this time, the first arm 3221 is pulled to resist the tension of the tension spring 3222 and move toward the middle area for a certain displacement to compensate for the horizontal displacement, thereby ensuring that the pressing piece 332 can effectively press the metal plate 5 to bend the metal plate 5.

[0051] Embodiment 3 refer to Fig.18 The present application provides a bending and shaping device for a metal plate 5, which is different from the second embodiment in that, with reference to the figure, a second elastic member 325 is provided between the two arm plates 322 and the connecting plate seat 330, and the elastic directions of the two second elastic members 325 on the connecting plate seat 330 are opposite and the elastic forces are equal. Figure 8 , Fig. 9The second elastic member 325 is a tension elastic member, such as a tension spring, a rubber elastic ring, etc. A hanging member 3220 is arranged on the arm plate 322 to be hung and matched with the second elastic member 325. Similarly, two second hanging members are arranged on the upper surface of the connecting plate seat 330 to be hung and matched with the two second elastic members 325. Through this arrangement, the first guide rail 34 can be guided to slide with the two arm plates 322, and the middle area of ​​the first guide rail 34 is locked and connected with the connecting plate seat 330. When the position of the arm plate 322 needs to be adjusted, the two arm plates 322 can be adjusted synchronously. At this time, the elastic force of the two second elastic members 325 ensures that the connecting plate seat 330 is at an equal distance from the two arm plates 322, thereby ensuring that the pressing member 332 is between the two arm plates 322, specifically, in actual application, a synchronous adjustment structure can be set between the two groups of connecting beams 320. For example, a bidirectional lead screw can be set under the support plate 315, and lead screw nuts are set at both ends of the bidirectional lead screw. The two lead screw nuts are respectively connected to the two groups of connecting beams 320, so that the displacement adjustment of the two arm plates 322 towards each other and away from each other can be achieved by rotating the bidirectional lead screw. It should be noted that the second elastic member 325 is in a stretched state that can provide tension to the connecting plate seat 330 when the two arm plates 322 are closest to each other. The bidirectional synchronous adjustment structure coordinated by the bidirectional lead screw and the lead screw nut is a commonly used existing technology in this field. The present application does not show or elaborate on its specific structure, and those skilled in the art should understand it.

[0052] Further, as a specific implementation, two first guide rails 34 are arranged in parallel and at intervals on the connecting plate seat 330 , and the two arm plates 322 are guided and slidably matched with the first guide rails 34 .

In the initial state where the limiting step 3234 abuts against the lower surface of the arm plate 322, the end plate 3232 and the upper surface of the limiting cylinder 328 are spaced apart, wherein at this time, the distance between the upper end of the limiting cylinder 328 and the lower surface of the end plate 3232 is h1; when the pressing member 332 is in the initial state, the vertical spacing distance between the lower end and the lower surface of the first suction cup 323 is h2, wherein h2=h1+(5cm-15cm).

[0054] Furthermore, a connecting piece 3270 is vertically arranged on each arm plate 322, and the connecting piece 3270 is connected to the limiting steps 3234 on the two first rigid rods 3230, and a pin shaft 32701 is horizontally arranged on the upper end of the connecting piece 3270, and the axis of the pin shaft 32701 is perpendicular to the guiding direction of the first guide rail 34.

At this time, the states of the first swing arm 3271 and the second swing arm 3273 are as follows: Fig.12 , Fig.13 As shown, the first swing arm 3271 is provided with a bar hole 32710 that matches the pin shaft 32701. At this time, the states of the first swing arm 3271 and the second swing arm 3273 are as follows: Fig.12As shown, two groups of air nozzles 326 are arranged at intervals on the second swing arm 3273, and the two groups of air nozzles 326 are staggered in the vertical direction. At this time, the end of the second swing arm 3273 is deflected in the direction away from the pressing piece 332. At this time, the air nozzle 326 does not contact the side of the metal plate 5 arranged on the lifting frame 31, which facilitates the lifting and lowering of the lifting frame 31. When the metal plate 5 is taken or placed, the first suction cup 323 contacts and adsorbs the metal plate 5. Then, when the lifting frame 31 descends, the first rigid rod 3230 is pulled downward under the action of gravity of the metal plate 5 adsorbed by the first suction cup 323, the first compression spring 3231 is squeezed, and the connecting member 3270 is driven to move downward in the vertical direction. In the process of the connecting member 3270 moving downward, the pin 323 is used to push the first rigid rod 3230 downward. 2701 drives the first swing arm 3271 to swing, and during the swing, the first wheel 32720 and the second wheel 32730 drive the second swing arm 3273 to swing, thereby driving the lower end of the second swing arm 3273 to swing in the direction close to the pressing member 332, and contacting the side of the metal plate 5 set on the lifting frame 31. When the end plate 3232 contacts the upper end of the limiting cylinder 328, the first swing arm 3271 stops and no longer deflects. At this time, the air nozzle 326 can approach the side of the metal plate 5 or contact the side of the metal plate 5. By setting the air nozzle 326, gas can be sprayed through the air nozzle 326, which is conducive to the air flow entering between the stacked metal plates 5 and is more convenient for separating adjacent metal plates 5. After the first suction cup 323 releases the metal plate 5 on the first supporting plate 21, the first swing arm 3271 returns to the initial position under the elastic force of the first compression spring 3231, and will not hinder the lifting plate.

[0055] Further, as a specific implementation, the first wheel 32720 and the second wheel 32730 can be any one of a gear and a friction wheel, preferably a friction wheel.

Specifically, the transport unit 4 includes two second guide rails 41 arranged at intervals and a first movable frame 42 slidably arranged on the second guide rails 41, wherein the first movable frame 42 includes two cross beams arranged perpendicularly to the second guide rails 41, and the first movable frame 42 can be driven by existing drive structures such as a ball screw drive structure and a rack and pinion linear reciprocating drive structure to achieve the purpose of the first movable frame 42 moving on the second guide rails 41. Three groups of suction cup assemblies 43 are arranged on the first movable frame 42, and the three groups of suction cup assemblies 43 can be slidably adjusted on the cross beams, so that the spacing distance can be adjusted according to the size of the plate to be bent to adapt to plates of different sizes.

[0057] Specifically, the specific structure of each suction cup assembly 43 is as follows: the suction cup assembly 43 includes a second movable frame 430 slidably arranged on the first movable frame 42, a power telescopic member 431 vertically arranged on the second movable frame 430, and a second suction cup 432 arranged at the lower end of the power telescopic member 431. Specifically, the second movable frame 430 is slidably matched with the crossbeam guide, and the power telescopic member 431 is vertically arranged on the second movable frame 430, wherein the power telescopic member 431 can be any one of a pneumatic telescopic rod and an electric telescopic rod, preferably a pneumatic telescopic rod, and a suction cup seat is fixed at the lower end of the power telescopic member 431, and two second suction cups 432 are arranged on the suction cup seat. It should be noted that in the present application, the first suction cup 323 and the second suction cup 432 are both air suction cups, and the control methods of the first suction cup 323 and the second suction cup 432 both adopt existing technologies, that is, by connecting the negative pressure air pump and the air release valve, when the metal plate 5 needs to be adsorbed, the air release valve is closed, and the negative pressure air pump is controlled to provide negative pressure suction for the suction cup. When the metal plate 5 needs to be released, the negative pressure air pump is controlled to stop working, and the air release valve is controlled to open to release the negative pressure, so that the metal plate 5 can be released. The above-mentioned control structure and method are the commonly used structures and methods of suction cups in this field, and technical personnel in this field should understand.
