DETAILED DESCRIPTION

[0030] The present invention discloses a vacuum breaking mechanism, which uses a plate suction device to lift the corners of a plate, then uses a vacuum breaking support plate to insert from the lifted corners, and sets an air blowing device to evenly introduce air, so that the tightly adsorbed plates can be separated smoothly, effectively preventing the plates from being deformed due to forced separation, ensuring the flatness and dimensional accuracy of the plates, and improving the quality of the plates. The vacuum breaking method of the present invention can improve work efficiency and reduce the risks caused by improper manual operation.

[0031] The following is a clear and detailed description of the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0032] See also Figures 1 to 5 The present invention provides a vacuum breaking mechanism for separating a plate from a plate pile, comprising a frame 1, a lifting device 2, a plate suction device 3, a vacuum breaking support plate 4 and a blowing device 5; the lifting device 2 and the blowing device 5 are respectively connected to the frame 1; the plate suction device 3 and the vacuum breaking support plate 4 are respectively connected to the lifting device 2 and are lifted and lowered by the lifting device 2; the plate pile is composed of multiple plates, wherein the plate located at the top is the first plate, and the plate located below the first plate is the second plate; the plate suction device 3 is used to absorb the corners of the first plate, and under the action of the lifting device 2, the first plate is lifted so that a gap is formed between the first plate and the second plate; the vacuum breaking tray is used to be inserted into the gap between the first plate and the second plate; the blowing device 5 is used to blow air into the plate pile.

[0033] The plate stack is formed by stacking multiple plates. In this embodiment, the plate at the top of the plate stack is defined as the first plate, and the plate adjacent to the first plate is defined as the second plate. The vacuum breaking mechanism of this embodiment mainly has four functional components, namely, a plate suction device 3 responsible for sucking up the plates, a vacuum breaking support plate 4 inserted between two plates to better separate the plates, an air blowing device 5 for blowing air into the plate stack to allow more air to enter the gap between the plates to prompt the plates to enter the vacuum breaking state faster, and a lifting device 2 responsible for lifting or lowering the plate suction device 3 and the vacuum breaking support plate 4.

[0034] The plate suction device 3 uses a vacuum suction device to suck the plate. Compared with the traditional plate suction device that directly acts on the entire plate or acts on the area where the center of gravity of the plate is located, the plate suction device 3 in this embodiment acts on the corners of the plate. Taking a common rectangular plate as an example, the area where the plate suction device 3 acts is the corner closest to the vacuum breaking mechanism among the four corners of the rectangular plate. When the plate suction device 3 sucks this corner, and then driven by the lifting device 2, the plate can be lifted up through this corner.

[0035] When the plate is slightly tilted and the gap is exposed, the vacuum-breaking support plate 4 can be inserted from the gap, and the first plate and the second plate are gradually separated in coordination with the movement of the plate suction device 3. By setting the vacuum-breaking support plate 4, some heavy plates, such as large-sized wooden boards and metal plates, can be effectively lifted. These heavy plates are difficult to separate if they are only adsorbed. The vacuum-breaking support plate 4 of this embodiment can be a support plate with a long strip structure. The support plate is inserted into the gap to gradually destroy the tight fit between the two plates, which greatly improves the efficiency of vacuum breaking.

[0036] The blowing device 5 mainly utilizes the principle of gas flow and pressure balance. When the first plate and the second plate are closely attached to each other, a near-vacuum state is formed between the two plates, and the internal air pressure at the attached position is lower than the external atmospheric pressure. The blowing device 5 blows air into the gap between the first plate and the second plate, that is, introduces external air into the space between the two plates. According to the characteristic of gas flowing from a high-pressure area to a low-pressure area, the blown air will enter the negative pressure area along the gap. As the air continues to enter, the air pressure between the two plates gradually increases. When the air pressure reaches or approaches equilibrium with the external atmospheric pressure, the vacuum state is destroyed.

[0037] Through the above-mentioned structural setting, the vacuum breaking mechanism can lift the plate evenly and slowly, and improve the separation efficiency of the heavier plates by inserting the vacuum breaking support plate 4 into the gap, and then introduce air to make the pressure on both sides of the plate change smoothly, effectively preventing the plate from being deformed due to sudden pressure change, ensuring the flatness and dimensional accuracy of the plate, and improving the quality and pass rate of the plate.

[0047] A vacuum breaking method, applied to the vacuum breaking mechanism according to any one of claims 1 to 9, the vacuum breaking method comprising the following steps:

[0049] In this step, the lifting device 2 acts on the plate suction device 3 and the vacuum breaking support plate 4, and drives both to rise or fall at the same time.

[0050] Step S2: the plate suction device 3 is started and rotated to the top of a corner of the first plate, and then the lifting device 2 drives the plate suction device 3 and the vacuum breaking support plate 4 to descend, so that the plate suction device 3 contacts the corner of the first plate, and the plate suction device 3 sucks the corner;

[0051] In this step, when the lifting device 2 drives the plate suction device 3 to rise to the top of the plate pile, the plate suction device 3 is activated and rotates to the top of the corner of the first plate. The lifting device 2 then descends to make the plate suction device 3 contact with the first plate. The plate suction device 3 starts the adsorption function and sucks the corner of the first plate.

[0052] Step S3: The lifting device 2 drives the plate suction device 3 to rise, and the plate suction device 3 sucks the corners of the first plate to make the first plate tilt up; in this step, after the plate suction device 3 sucks the first plate, the lifting device 2 drives the plate suction device 3 to rise, and the plate suction device 3 applies a pulling force to the corners of the first plate, so that the corners of the first plate slowly tilt upward. Compared with the traditional equipment that directly acts on the entire plate, the lifting device 2 in this step only acts on the corners of the first plate, and the force points of the first plate are more concentrated, making it easier to tilt up.

[0053] Step S4: The vacuum-breaking support plate 4 is started and inserted into the gap between the first plate and the second plate to separate the first plate from the second plate. The vacuum-breaking support plate 4 is inserted in a rotating manner. When a gap is generated between the first plate and the second plate, the vacuum-breaking support plate 4 can be inserted into the gap and continue to penetrate deeper into between the first plate and the second plate after being inserted into the gap to separate the two.

[0054] Step S5: the blowing device 5 blows air toward the plate stack to introduce external air into the space between the first plate and the second plate;

[0055] Compared with the method of blowing air directly toward the gap, the blowing device 5 in this step adopts a large-scale blowing method to spray the airflow toward the direction of the plate stack, and its structure is simpler and the operation is more stable.

[0056] Step S6: The vacuum breaking pallet 4 continues to be inserted until the vacuum state between the first plate and the second plate is eliminated, and the vacuum breaking operation between the first plate and the second plate is completed; in this step, the vacuum breaking is achieved by the simple insertion action of the vacuum breaking pallet 4, without the need for complex equipment or cumbersome operating procedures, and the vacuum breaking operation can be completed quickly and effectively, thereby improving work efficiency and saving time and labor costs.

[0057] Step S7: Remove the first plate by means of a picking device or a manipulator; in this step, a picking device commonly used on the production line can be used, such as a vacuum suction cup 307-type picking device, a mechanical gripper-type picking device, or a manipulator can be used for picking operations according to different picking tasks and environments. Both can accurately grasp the first plate, improve picking efficiency, and reduce impact on the vacuum breaking mechanism.

[0058] Step S8: the vacuum breaking support plate 4 and the plate suction device 3 are reset, and the lifting device 2 drives the vacuum breaking support plate 4 and the plate suction device 3 to move to the top of the second plate to start the vacuum breaking operation of the second plate.

[0059] The vacuum breaking mechanism provided by the present invention can smoothly separate the closely adsorbed plates by lifting the corners of the plates in the plate suction device, inserting the vacuum breaking support plate from the lifted corners, and evenly introducing air by setting an air blowing device, thereby effectively preventing the plates from being deformed due to forced separation, ensuring the flatness and dimensional accuracy of the plates, and improving the quality of the plates. The vacuum breaking method of the present invention can simplify the operation process of plate separation. By simply pressing a button or starting a related control program, the vacuum breaking operation process between the plates can be automatically completed without the need for the operator to perform complex manual operations, thereby improving work efficiency and reducing the risks caused by improper manual operations.
