Description

Technical Field

[0002] Steel strip, also known as strip steel, is within 1300mm in width and its length varies slightly according to the size of each roll. Strip steel is generally supplied in rolls and has the advantages of high dimensional accuracy, good surface quality, easy processing and material saving.

[0003] Before the steel strip is used in production, it needs to be straightened and cut into pieces according to the required length and width. The cut pieces are usually directly transported to the subsequent production line, or multiple pieces are transported to the processing site after being palletized and packaged.

[0004] As for the grabbing of stacked sheets, since the sheets are thin and easily deformed, it is difficult to remove them from the sheet pile by clamping. Therefore, the sheet transfer device with a suction cup is usually used to grab and transfer the top sheet. However, since the steel strip sheet is easily deformed, when the suction cup device is used to absorb and grab the sheet, the sheet may fall from the suction cup device due to vibration and deformation during the transfer process, causing damage to the sheet.

[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0037] like Figures 1 to 6 As shown, the clamping device applied to steel strips of different specifications includes a T-shaped frame 1, a hollow clamping plate 2, a spacing adjustment mechanism 3, a floating plate 4, a movable clamping plate 5 and a clamping plate driving mechanism 6. Hollow clamping plates 2 are arranged at intervals on both sides of the T-shaped frame 1. The hollow clamping plates 2 are connected to the T-shaped frame 1 through the spacing adjustment mechanism 3 and are driven by the spacing adjustment mechanism 3 to approach and move away from the T-shaped frame 1.

[0038] A floating cavity 7 is provided in the hollow splint 2, and a floating plate 4 is floated in the floating cavity 7. A plurality of suction cups 8 are provided at the bottom of the floating plate 4, and a suction cup control assembly 9 connected to the suction cups 8 is provided at the top of the floating plate 4. An avoidance hole 10 for the suction cups 8 to enter is provided at the bottom of the hollow splint 2;

[0039] The upper end of the movable splint 5 is hingedly arranged on the outer side of the hollow splint 2 away from the T-shaped frame 1. The splint driving mechanism 6 is arranged on the hollow splint 2 and connected to the movable splint 5. The splint driving mechanism 6 drives the movable splint 5 to rotate so that the movable splint 5 pushes the sheet material to rise during the process of rotating upward from the lower end of the sheet material adsorbed by the suction cup 8 until the movable splint 5 cooperates with the hollow splint 2 to clamp the sheet material.

[0040] Specifically, the T-shaped frame 1 is connected to sheet material transfer equipment such as a mechanical arm and a crane, and the spacing adjustment mechanism 3 adjusts the spacing between the suction cups 8 on both sides and the movable clamps 5 on both sides by driving the hollow clamp 2 to approach and move away from the T-shaped frame 1 to adapt to sheets of various sizes. The T-shaped frame 1 is driven down by the transfer equipment so that the suction cup 8 is pressed on the sheet material at the top of the stacked sheet material pile. At this time, the suction cup control component 9 extracts the gas in the suction cup 8 so that the suction cup 8 absorbs the sheet material. Subsequently, the T-shaped frame 1 is driven up by the transfer equipment, and the clamp driving mechanism 6 drives the movable clamp 5 to rotate so that the lower end of the movable clamp 5 rotates toward the bottom of the sheet material. When the movable clamp 5 rotates to the bottom of the sheet material, as the movable clamp 5 continues to rotate, the lower end of the movable clamp 5 will rotate upward and push the sheet material until the sheet material adsorbed by the suction cup 8 is pushed by the movable clamp 5 to contact the bottom of the hollow clamp 2. At this time, the two sides of the sheet material are clamped by the hollow clamp 2 and the movable clamps 5 on both sides. While the sheet material is pushed upward by the movable clamping plate 5, the floating plate 4 rises accordingly. When the sheet material is clamped by the movable clamping plate 5 and the hollow clamping plate 2, the suction cup 8 is located in the avoidance hole 10, thereby ensuring that the sheet material can be clamped by the movable clamping plate 5 and the hollow clamping plate 2.

[0041] The present invention adjusts the distance between the hollow splint 2 and the T-shaped frame 1 through the distance adjustment mechanism 3 to meet the needs of clamping sheets of various sizes, and the suction cup 8 floating plate equipped with the suction cup 8 is floated in the floating cavity 7 of the hollow splint 2. After the suction cup 8 adsorbs the sheet, the movable splint 5 on the outside of the hollow splint 2 is driven by the splint driving mechanism 6 to push the sheet up until the movable splint 5 cooperates with the hollow splint 2 to clamp the sheet. The floating design of the suction cup 8 floating plate and the avoidance hole 10 design at the bottom of the hollow splint 2 ensure that the sheet can be clamped by the hollow splint 2 and the movable splint 5, avoiding the problem of the sheet falling during the grasping process due to the single adsorption method of the suction cup 8.

[0042] The clamping plate driving mechanism 6 includes a transmission shaft 601, a transmission gear 602, a transmission rack 603 and a lifting assembly 604. Both ends of the transmission shaft 601 are rotatably arranged on the outer side of the hollow clamping plate 2 through the end shaft seat 11. The transmission gear 602 is coaxially and fixedly arranged on the transmission shaft 601.

[0043] The outer side of the hollow clamping plate 2 is provided with a guide groove 12 which penetrates the top and bottom thereof and communicates with the floating cavity 7. The transmission rack 603 is slidably plugged into the guide groove 12, and the outer side of the transmission rack 603 is meshedly connected with the transmission gear 602.

[0044] The upper end of the movable clamping plate 5 is connected to the transmission shaft 601, the inner side of the transmission gear 602 is connected to the floating plate 4, the lifting component 604 is arranged on the hollow clamping plate 2 and connected to the floating plate 4, the floating plate 4 is lifted and lowered by the lifting component 604, and the lifting component 604 drives the floating plate 4 to rise, so that the transmission rack 603 drives the movable clamping plate 5 to clamp the sheet material with the help of the transmission gear 602 and the transmission shaft 601.

[0045] When the lifting assembly 604 drives the floating plate 4 to rise, the transmission rack 603 rises accordingly, and at the same time, the inner side of the driving gear 602 that is meshed with the transmission rack 603 rotates upward, and the transmission gear 602 drives the transmission shaft 601 equipped with the movable splint 5 to rotate. Taking the initial position of the movable splint 5 that is vertical relative to the hollow splint 2 and with the lower end facing downward as an example, at this time, the lower end of the right movable splint 5 rotates to the upper left, and after contacting the sheet material, it pushes the sheet material up until the sheet material collides with the bottom of the hollow splint 2.

[0046] Moreover, the movable splint 5 is in a curved shape with the lower end bent toward one side of the T-shaped frame 1, so that the lower end of the movable splint 5 contacts the sheet material. If the movable splint 5 is in a straight line, the movable splint 5 contacts the side of the sheet material by approaching the inner side of the T-shaped frame 1, and the contact position moves toward the upper end of the movable splint 5 as the lower end of the movable splint 5 rotates upward. On the one hand, when the movable splint 5 contacts the sheet material, if the movable splint 5 and the sheet material are vertical or nearly vertical, the straight movable splint 5 cannot or is difficult to push the sheet material up. On the other hand, as the movable splint 5 pushes the sheet material, the contact position of the two will move toward the upper end of the movable splint 5, and the end point of the rising of the sheet material is easily restricted by the position of the upper end of the straight movable splint 5, while the curved movable splint 5 contacts the bottom of the sheet material through the lower end, and the contact position of the two moves horizontally along the bottom of the sheet material as the movable splint 5 rotates, and will not be restricted by the position of the upper end of the movable splint 5.

[0047] Preferably, movable clamping plates 5 are provided at both ends of the transmission shaft 601 , and the transmission gear 602 is located between the movable clamping plates 5 at both ends.

[0048] Preferably, center shaft seats 13 are spaced apart on the outer sides of the hollow splint 2, the transmission gear 602 is located between the two center shaft seats 13, the center shaft seat 13 is located between the transmission gear 602 and the corresponding movable splint 5, and an axis hole is provided on the center shaft seat 13 for the transmission shaft 601 to pass through and rotate.

[0049] Among them, the lifting assembly 604 includes a screw 6041 and a servo motor 6042. The servo motor 6042 is arranged on the top of the hollow clamping plate 2. The lower end of the screw 6041 is rotatably arranged on the cavity wall at the bottom of the floating cavity 7. The upper end of the screw 6041 is connected to the servo motor 6042, and the floating plate 4 is connected to the nut of the screw 6041.

[0050] Wherein, both ends of the floating plate 4 are provided with through holes for the corresponding lead screw 6041 to pass through, the nut of the lead screw 6041 is located in the through hole, and the nut is connected to the floating plate 4 through a fixing screw.

[0051] Among them, the spacing adjustment mechanism 3 includes a horizontal cylinder 301 and an inclined cylinder 302. One end of the horizontal cylinder 301 is embedded in the T-shaped frame 1, and the other end of the horizontal cylinder 301 is connected to the inner side of the hollow plywood 2. The inclined cylinder 302 is located above the horizontal cylinder 301, and the inclined cylinder 302 is inclined relative to the horizontal cylinder 301. The upper end of the inclined cylinder 302 is hinged to the T-shaped frame 1, and the lower end of the inclined cylinder 302 is hinged to the top of the hollow plywood 2. The inclined cylinder 302 with adjustable angle and length is used to share the load from the gravity of the hollow plywood 2 borne by the horizontal cylinder 301, which helps to reduce the problem of increased loss of the horizontal cylinder 301 due to bearing vertical loads.

[0052] Among them, the T-shaped frame 1 includes a base frame 101 embedded with a horizontal cylinder 301 and a vertical frame 102 arranged on the top of the base frame 101, one end of the inclined cylinder 302 is hinged to the side wall of the vertical frame 102, and a connecting column 14 for connecting a sheet material transfer device is arranged on the top of the vertical frame 102, and the shape of the connecting column 14 is formulated accordingly according to the sheet material transfer device.
