Description

Technical Field

[0001] This utility model relates to the field of plate loading machine technology, specifically a suction cup plate loading machine with self-correction function. Background Technology

[0002] A panel loading machine is a mechanical device used to automatically load and unload materials such as boards and sheets. It is widely used in production lines in industries such as wood, metal, and plastics. During the production process, the boards are pre-pressed before hot pressing according to their production process. After pre-pressing, the entire stack of boards needs to be separated and loaded onto the panel loading machine.

[0003] As disclosed in the prior art, Chinese Patent Publication No. CN103964219A discloses a novel fully automatic pallet loading machine, characterized by comprising a lower transmission device, a pallet lifting device, an upper transmission device, and a circuit control system. The lower transmission device is connected to the pallet lifting device, and the pallet lifting device is connected to the upper transmission device, simplifying the driving method and reducing equipment maintenance costs and the complexity of mechanical repair. The small-scale pallet correction method does not require high-torque driving, the mechanism is simple with low wear and tear, and no additional power is needed. The addition of a pallet receiving and placing function solves the practical deficiencies of existing pallet loading machines and the aforementioned technical problems.

[0004] Based on the above information, existing technologies generally use a lifting platform to raise the boards before loading them into the machine. However, in actual use, this method still requires manual operation. After the boards are raised by the lifting platform, they still need to be manually moved into the machine. This is labor-intensive, and the operators are close to the machine during this process, which poses a certain degree of danger. Utility Model Content

[0005] The purpose of this invention is to provide a suction cup loading machine with self-correction function to solve the problems of high labor intensity and danger mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a suction cup loading machine with self-correcting function, comprising a mounting frame fixedly installed with the assembly line equipment, wherein a negative pressure fan and a drive motor are fixedly installed on the left side of the mounting frame by bolts, and further comprising:

[0007] A horizontally arranged guide frame is fixedly installed on the upper end of the mounting frame, and a connecting sleeve is installed on the outside of the guide frame, and the connecting sleeve and the guide frame form a through sliding structure.

[0008] A support beam is installed between the connecting sleeves on the left and right sides. The support beam is divided into a fixed beam and a movable beam that are separated from each other. The fixed beam is fixedly welded to the connecting sleeve, and the movable beam is not in contact with the connecting sleeve. A lifting mechanism that drives the movable beam to move is provided above the fixed beam.

[0009] Vacuum suction cups are fixedly installed at equal intervals on the lower surface of the movable beam, and the vacuum suction cups are connected to the negative pressure fan through pipes;

[0010] The mounting frame has a lower pressure roller and an upper pressure roller rotatably mounted inside. The lower pressure roller is driven to rotate by a drive motor through a chain and sprocket. The mounting frame also has an adjustment mechanism for adjusting the height of the upper pressure roller.

[0011] Preferably, a first cylinder is fixedly mounted on the upper surface of the mounting frame, and the telescopic end of the first cylinder is connected to the fixed beam.

[0012] Preferably, a calibration cylinder is fixedly installed at both the left and right ends of the front side of the mounting frame, and a calibration plate is fixedly installed at the telescopic end of the calibration cylinder, the calibration plate being laterally telescopic relative to the mounting frame.

[0013] Preferably, the lifting mechanism includes a mounting block fixedly installed above the fixed beam, and a third cylinder is fixedly installed on the upper surface of the mounting block, and a connecting plate located inside the mounting block is fixedly installed at the output end of the third cylinder.

[0014] Preferably, the connecting plate forms an up-and-down telescopic structure with the mounting block via a third cylinder, and two guide rods are slidably installed through the inside of the connecting plate.

[0015] Preferably, the bottom end of the guide rod is fixedly installed between the guide rod and the upper surface of the movable beam, and a buffer spring for relieving force is provided on the outside of the guide rod.

[0016] Preferably, the adjusting mechanism includes a connecting roller for mounting the upper pressure roller, and a second cylinder is rotatably mounted on the outer surface of the connecting roller, and the upper end of the second cylinder is rotatably connected to the mounting frame.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the suction cup loading machine with self-correction function adopts a novel structural design, the specific details of which are as follows:

[0018] 1. After the traditional lifting mechanism lifts the board to a certain height, the board is picked up and moved by the push of the first cylinder in conjunction with the negative pressure fan and vacuum suction cup. Then, the lower pressure roller is driven by the drive motor to rotate and automatically fill the board into the equipment. The whole process does not require manual operation, which saves time and effort and avoids danger.

[0019] Furthermore, during the loading process, the correction cylinder is used to move the correction plate, and the correction plates on the left and right sides move synchronously to push the plate to the middle position, thereby achieving the purpose of correction.

[0020] Furthermore, the vacuum suction cup is connected to the movable beam, which is connected to the connecting plate via a guide rod at its upper end. The movable beam moves up and down by the extension and retraction of the third cylinder. Since the movable beam and the extension cylinder are not fixedly installed, even if a malfunction occurs (such as the plate falling off), the lifting mechanism can be protected to a certain extent by the buffering effect of the buffer spring, thus avoiding damage.

[0021] 2. By adjusting the extension and retraction of the second cylinder in the adjustment mechanism, the connecting roller can be rotated. In turn, the rotation of the connecting roller drives the upper pressure roller installed on its exterior to move up and down, changing the distance between the upper and lower pressure rollers, thus adapting to plates of different thicknesses.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1: Please refer to Figures 1-4To achieve automatic loading and correction, this embodiment provides the following technical solution: a mounting frame 1 fixedly installed with the assembly line equipment. A negative pressure fan 2 and a drive motor 3 are bolted to the left side of the mounting frame 1. A horizontally arranged guide frame 4 is fixedly installed at the upper end of the mounting frame 1, and a connecting sleeve 5 is installed on the outside of the guide frame 4. The connecting sleeve 5 and the guide frame 4 form a through-type sliding structure. A supporting beam 6 is installed between the connecting sleeves 5 on the left and right sides. The supporting beam 6 is divided into a fixed beam 601 and a movable beam 602, which are separated from each other. The fixed beam 601 is fixedly welded to the connecting sleeve 5, and the movable beam 602 does not contact the connecting sleeve 5. A lifting mechanism is provided above the fixed beam 601 to drive the movable beam 602 to move. The lifting mechanism includes components fixedly installed on the fixed beam. The mounting block 15 is located above 601, and a third cylinder 16 is fixedly mounted on the upper surface of the mounting block 15. A connecting plate 17 located inside the mounting block 15 is fixedly mounted on the output end of the third cylinder 16. Vacuum suction cups 10 are fixedly mounted at equal intervals on the lower surface of the movable beam 602. The vacuum suction cups 10 are connected to the negative pressure fan 2 through pipes. A lower pressure roller 8 and an upper pressure roller 9 are rotatably mounted on the inner side of the mounting frame 1. The lower pressure roller 8 is driven to rotate by a drive motor 3 through a chain and sprocket. A first cylinder 7 is fixedly mounted on the upper surface of the mounting frame 1. The telescopic end of the first cylinder 7 is connected to the fixed beam 601. A correction cylinder 11 is fixedly mounted on the left and right ends of the front side of the mounting frame 1. A correction plate 12 is fixedly mounted on the telescopic end of the correction cylinder 11. The correction plate 12 extends and retracts laterally relative to the mounting frame 1.

[0031] When using the device, the mounting frame 1 is first fixedly installed in the equipment where the plate needs to be loaded. Then, the plate is lifted to the specified height (i.e., the height matching the mounting frame 1) using a traditional lifting device. Next, the first cylinder 7 is activated, which pushes the connecting sleeve 5 to slide outside the guide frame 4. During the sliding of the connecting sleeve 5, the supporting beam 6 on its inner side moves synchronously, finally moving the vacuum suction cup 10 above the plate. The negative pressure fan 2 is then turned on to extract the air from the vacuum suction cup 10, thereby adsorbing the plate under negative pressure. After adsorption, the first cylinder 7 retracts, moving the plate to the inside of the mounting frame 1. During this process, the correction cylinder 11 is activated, pushing the correction plate 12 to move towards the center, thereby pushing the plate to the center position to achieve the purpose of correction. After the plate enters the mounting frame 1 (at this time, the plate is located between the lower pressure roller 8 and the upper pressure roller 9), the drive motor 3 drives the lower pressure roller 8 to rotate through the sprocket and chain, conveying the plate and achieving the purpose of automatic loading.

[0032] Example 2: Please refer to Figure 5In order to protect the lifting mechanism and vacuum suction cup 10, this embodiment provides the following technical solution, which specifically discloses that: the connecting plate 17 forms an up-and-down telescopic structure with the mounting block 15 through the third cylinder 16, and two guide rods 18 are slidably installed inside the connecting plate 17. The bottom end of the guide rods 18 is fixedly installed between the upper surface of the movable beam 602, and a buffer spring 19 for relieving force is provided on the outside of the guide rods 18.

[0033] When the vacuum suction cup 10 moves above the board, the third cylinder 16 is activated, which pushes the movable beam 602 downward, thereby pressing the vacuum suction cup 10 tightly against the surface of the board. During this process, the connecting plate 17 can slide relative to the guide rod 18, thus achieving a non-fixed soft connection. In addition, the buffer spring 19 outside the guide rod 18 can protect the lifting mechanism or the vacuum suction cup 10 in case of failure, preventing damage.

[0034] Example 3: Please refer to Figure 6 In order to achieve the purpose of adjusting the distance between the upper pressure roller 9 and the lower pressure roller 8, this embodiment provides the following technical solution, which specifically discloses that: an adjustment mechanism for adjusting the height of the upper pressure roller 9 is provided on the inner side of the mounting frame 1. The adjustment mechanism includes a connecting roller 13 for mounting the upper pressure roller 9, and a second cylinder 14 is rotatably mounted on the outer surface of the connecting roller 13, and the upper end of the second cylinder 14 is rotatably connected to the mounting frame 1.

[0035] When dealing with plates of different thicknesses, the second cylinder 14 is activated. The extension and retraction of the second cylinder 14 causes the connecting roller 13 inside the mounting frame 1 to rotate, thereby causing the connecting roller 13 to drive the upper pressure roller 9 outside it to move up and down, changing the distance between the upper pressure roller 9 and the lower pressure roller 8, thus realizing the conveying of plates of different thicknesses.
