Technical Field

[0001] The utility model relates to the technical field of aluminum plate processing devices, in particular to an aluminum plate suction lifting and stacking device. Background Art

[0002] After the sheet aluminum plate is subjected to surface grinding treatment (one side has a grinding brush surface, and the other side has an anodized protective film surface), multiple aluminum plates can be sequentially conveyed to the blanking position through a production line, and then sucked and lifted by an automatic suction lifting device and stacked. For example, an adjustable vacuum suction lifting device with the application number 201720135332.X is used to adsorb, transfer, and blank the aluminum plate.

[0003] However, when directly blanking and stacking using the above-mentioned suction lifting device, suction cup marks will be left on the ground aluminum plate after grinding treatment, affecting the appearance quality of the aluminum plate; moreover, during the stacking process of the aluminum plates, manual operation is still required to first lay a cushion layer on the aluminum plate to protect the grinding brush surface on the aluminum plate, and then stack the next aluminum plate on the upper end of the cushion layer. This not only increases the labor intensity of the operator and has low efficiency, but also requires a large space for operation. Summary of the Utility Model

[0027] The following are specific embodiments of the utility model in combination with the drawings, and the technical solutions of the utility model are further described, but the utility model is not limited to these embodiments.

[0028] Such as Figures 1 to 3As shown in the figure, an aluminum plate suction lifting and stacking device includes a frame 10, an aluminum plate feeding mechanism 20, a cushion feeding mechanism 30, a positioning mechanism 40, a suction lifter 50, and a receiving table 60. The aluminum plate feeding mechanism 20 is arranged on the frame 10 for conveying aluminum plates. The positioning mechanism 40 is arranged on the frame 10 and is located on one side of the aluminum plate feeding mechanism 20 for positioning the conveyed aluminum plates. The cushion feeding mechanism 30 includes a storage table 31 arranged on the aluminum plate feeding mechanism 20 and a guiding member 32. The storage table 31 is used for stacking the flexible cushion 70 with a pore structure. On one side of a pair of guiding members 32 close to each other, there are respectively inclined guiding grooves 320 for feeding the flexible cushion 70 to the upper end of the positioned aluminum plate. The suction lifter 50 is arranged above the positioning mechanism 40. The suction cup 51 of the suction lifter 50 abuts against the flexible cushion 70 on the aluminum plate, adsorbs the flexible cushion 70 and the aluminum plate together, and then transfers them to the receiving table 60. For example, the flexible cushion 70 can be selected as double-sided glazed paper with a pore structure. The grammage of the double-sided glazed paper is preferably 70 g / cm 2 , which has a certain stiffness effect and does not completely seal the pore structure it has. The double-sided glazed paper allows gas molecules to pass through its body to achieve the corresponding vacuum degree between the suction cup 51 and the aluminum plate, and then the aluminum plate is adsorbed by the suction cup 51. Further, the suction cup 51 is made of silica gel material, with an outer diameter of 30 - 40 mm and a special structure with a thicker middle and thinner edges. In addition, the flexible cushion 70 can also be selected as other forms of paper or protective film, and a plurality of adsorption holes 700 allowing gas to pass through need to be arranged on it to form a pore structure.

[0029] In the present utility model, after the aluminum plate is fed by the aluminum plate feeding mechanism 20, it is located on the positioning mechanism 40. Then, a flexible cushion 70 is fed from the storage table 31 to the upper end of the aluminum plate through the inclined guiding groove 320 on the guiding member 32 by manual operation or mechanical operation. The flexible cushion 70 and the aluminum plate thus form a stacked state. The suction lifter 50 is moved so that its suction cup 51 is located above the positioning mechanism 40. Since the flexible cushion 70 has a pore structure, the suction cup 51 can adsorb the flexible cushion 70 and the aluminum plate together through the negative pressure formed by it (after passing through the pore structure), and move the two and place them on the receiving table 60. After the suction cup 51 is desorbed, it returns to its original position. By repeating the above actions, multiple aluminum plates can be stacked separately with the flexible cushion 70 spaced between them.

[0030] The present utility model can avoid the formation of suction cup marks on the aluminum plate through the pore structure on the flexible cushion 70, and can adsorb the flexible cushion 70 and the aluminum plate together and then transfer them. The transferred flexible cushion 70 and aluminum plate are stacked together as a whole. The presence of the flexible cushion between adjacent aluminum plates can avoid manually placing the cushion, improving the stacking efficiency of the aluminum plates.

[0031] The aluminum plate feeding mechanism 20 includes a belt feeding line 21 and a roller assembly 22. The belt feeding line 21 is arranged on the frame 10 for feeding aluminum plates. A corresponding stop member can be arranged at the end of the belt feeding line 21 to ensure that only one aluminum plate enters the positioning mechanism 40 each time. The roller assembly 22 guides the aluminum plate to the positioning mechanism 40 through its pressing roller 221. The function of the pressing roller 221 can ensure that the aluminum plate enters the positioning mechanism 40 in a flat state.

[0032] Regarding the specific structure of the positioning mechanism 40, it includes a receiving line 41 and a positioning assembly. The receiving line 41 is arranged on the frame 10. Guide plates (not shown) can be respectively arranged on the opposite sides of one end of the receiving line 41 close to the belt feeding line 21 to ensure that the aluminum plate is located in the middle of the receiving line 41 for feeding. The positioning assembly includes a lifting cylinder 421 and a baffle 422. The lifting cylinder 421 is arranged at the end of the receiving line 41. The baffle 422 is arranged at the output end of the lifting cylinder 421 and is used to block the aluminum plate and the flexible cushion layer 70 on the receiving line 41 after being driven to rise, so as to accurately position them on the feeding line 41 and under the lifting crane 50.

[0033] Furthermore, the positioning mechanism 40 further includes a testing assembly (not shown). The testing assembly includes a spinning cylinder and a testing needle. The spinning cylinder is arranged on the receiving line 41, and the testing needle is arranged at the output end of the spinning cylinder. After being driven, it rotates and moves downward to abut against the positioned aluminum plate. Whether the aluminum plate is loaded in the correct posture is judged by whether the testing needle can conduct electricity after contacting the upper surface of the aluminum plate. The specific judgment method is as follows: when the testing needle can achieve a conductive state after contacting the upper surface of the aluminum plate, the upper surface of the aluminum plate is the grinding and brushing surface; when the testing needle cannot achieve a conductive state after contacting the upper surface of the aluminum plate, the upper surface of the aluminum plate is the anodic surface. When the conductive state (whether it conducts electricity) after the testing needle contacts the aluminum plate does not match the setting, an alarm will be triggered to remind the operator to flip the aluminum plate, and then the flexible cushion layer 70 is fed onto the aluminum plate. In addition, through the setting of the spinning cylinder, the testing needle can be driven to rotate above the positioning mechanism 40 or away from above the positioning mechanism 40 to avoid interference between the position of the testing needle and the lifting crane 50 when adsorbing and moving the flexible cushion layer 70 and the aluminum plate.

[0034] More specifically, the guiding member 32 includes a side plate 321 arranged on the aluminum plate feeding mechanism 20 and a guiding plate 322 arranged on the side plate 321. An inclined guiding groove 320 is formed on the guiding plate 322, and the width of the inclined guiding groove 320 gradually decreases along the feeding direction, and the height also gradually decreases along the feeding direction. That is, at the starting end position, the flexible cushion layer 70 can be easily fed into the inclined guiding groove 320, and at the end position, the flexible cushion layer 70 is aligned with the aluminum plate. The end position of the inclined guiding groove 320 should match the end position of the guiding plate for feeding the aluminum plate.

[0035] On the basis that the inclined guiding groove 320 is in an inclined state to facilitate the feeding of the flexible cushion layer 70, an inclined air hole 3220 communicating with the inclined guiding groove 320 is provided on the side plate 321. The inclined air hole 3220 is connected to an external air source and can convey gas with a certain pressure and flow rate towards the end position of the inclined guiding groove 320 for blowing the flexible cushion layer 70, so that the flexible cushion layer 70 can pass through and break away from the inclined guiding groove 320 more smoothly and then fall on the upper end of the aluminum plate.

[0036] As Figure 4 shown, in another embodiment of the present invention, the cushion feeding machine 30 further includes a feeding assembly 33. The feeding assembly 33 includes a bracket 331, a vertically arranged electric cylinder 332, a hanging bracket 333 and a pair of pushing parts 334. The bracket 331 is arranged on the aluminum plate feeding mechanism 20, the vertically arranged electric cylinder 332 is arranged on the bracket 331, and a hanging bracket 333 is provided at the output end. A pair of pushing parts 334 are arranged at opposite ends of the hanging bracket 333. The pushing part 334 includes a motor 3341 and a roller 3342. The motor 3341 is arranged on the hanging bracket 333, and the roller 3342 is arranged at the output end of the motor 3341 and is driven to abut against the uppermost flexible cushion layer on the storage table 31 and push the flexible cushion layer 70 into the inclined guiding groove 320, so as to realize the automatic feeding of the flexible cushion layer 70. It should be noted that, in matching with the feeding assembly 33, the position of the guiding plate 322 should extend as far as possible to the side of the storage table 31 so that the flexible cushion layer 70 can accurately enter the starting position of the inclined guiding groove 320.

[0037] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar ways to substitute, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
