Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of furnace door control, in particular to a furnace door control method and device in a boat pushing mechanism. BACKGROUND

[0002] The boat pushing mechanism generally involves a material table, a pushing plate, a furnace door and a reaction furnace body, etc. The reaction furnace body is one of the important components in the process of semiconductor device preparation, and is widely used in the industries of integrated circuits, power electronics and solar cell production. During the use of the reaction furnace body, there is a common phenomenon that the position of the furnace door cannot be accurately, quickly and smoothly controlled, which leads to problems such as insufficient sealing and poor heat dissipation of the reaction furnace body during work. The most direct impact is that the temperature in the furnace cannot meet the requirements, so that the quality of the final prepared products is poor. The reason for this series of problems is that the structure of the furnace door is relatively complex, and it is impossible to realize multi-cylinder control to increase the working pressure.

[0003] The traditional furnace door control is connected by the cylinder piston rod and the furnace door opening and closing lever, the furnace door opening and closing lever and the furnace door cover plate with a sealing plate, and the furnace door opening and closing lever and the furnace door cover plate are connected through a mounting shaft. Two axes perpendicular to each other are arranged between the furnace door cover plate and the opening and closing lever, so that the furnace door cover plate can automatically adjust the orientation when it is in contact with the end face of the furnace tube. With the increase of various devices on the furnace door, or the increase of the furnace type, the furnace door becomes heavier and heavier. This traditional furnace door control device cannot bear the weight of the furnace door. With the increase of the opening and closing times, the mounting shaft components will be deformed, which will lead to the problems of poor sealing of the furnace door, poor vacuum pumping, oxygen leakage and other problems. When the oxygen leakage is serious, it will also cause the product in the reaction furnace body to be scrapped, causing economic losses and affecting work efficiency.

[0069] The following is a description of the preferred embodiments of the present application in conjunction with the accompanying drawings.

[0070] As Figure 1 shown, the embodiments of the present application disclose a furnace door control method in a boat pushing mechanism, the method comprising:

[0071] S110: When the product to be processed enters the furnace body, a furnace door closing instruction is generated according to image information of the product to be processed.

[0072] In order to ensure the real-time of furnace door closing, in some embodiments of the present application, when the furnace door closing instruction is generated according to the image information of the product to be processed, specifically:

[0073] acquire image information of the region where the product to be processed is located in the furnace body, and determine whether to generate the furnace door closing instruction according to the relationship between the image information and a preset target region,

[0075] when the image information is not in the preset target region, the second motor is controlled to drive the product to be processed until the product to be processed is in the preset target region.

[0076] In the present embodiment, the image information of the region where the product to be processed is located in the furnace body can be acquired by an image sensor, and the preset target region in the present application refers to a designated region of the product to be processed in the furnace body. When the product to be processed reaches this region, the next operation can be performed. Therefore, when the product to be processed is in the preset target region, the furnace door closing instruction is generated. When the image information is not in the preset target region, the second motor is controlled to drive the product to be processed until the product to be processed is in the preset target region. At this time, the furnace door closing instruction is generated. The present application can ensure the real-time of furnace door closing by generating the furnace door closing instruction, and prevent the problem that the furnace door is closed before the product to be processed reaches the preset target region.

[0082] In the present embodiment, the preset position point can be arranged on the furnace body, and the furnace door position point can be arranged on the furnace door. The preset position point and the furnace door position point refer to two corresponding points. The infrared light receiving device is arranged at the furnace door position point, and the infrared light receiving device is arranged at the furnace door position point. When measuring the distance between the preset position point and the furnace door position point, the infrared light emitting device emits first infrared light to the infrared light receiving device, the infrared light receiving device receives the first infrared light, records the emission time node of the first infrared light and the receiving time node of the first infrared light, calculates the time node difference between the two, and determines the distance length between the preset position point and the furnace door position point according to the corresponding relationship between the time node difference and the preset time difference. The preset time difference refers to the data obtained by measuring the distance length between the preset position point and the furnace door position point in advance. Each preset time difference corresponds to a distance length. Therefore, according to the real-time obtained time node difference and the preset time difference, the distance length between the preset position point and the furnace door position point can be directly obtained. The present application can accurately obtain the angle to be rotated of the furnace door by obtaining the distance length between the preset position point and the furnace door position point, and realize accurate control of the furnace door.

[0088] According to the relationship between the distance length A between the door position point and the preset position point and each preset distance length, the rotation angle of the door is set:

[0089] When A

[0090] When B1

[0091] When B2

[0092] When B3

[0093] When B4, the fifth preset rotation angle C5 is selected as the rotation angle of the door.

[0094] In this embodiment, the distance length A between the door position point and the preset position point and each preset distance length is set according to the relationship between the distance length A between the door position point and the preset position point and each preset distance length, B1 is the first preset distance length, B2 is the second preset distance length, B3 is the third preset distance length, B4 is the fourth preset distance length, C1 is the first preset rotation angle, C2 is the second preset rotation angle, C3 is the third preset rotation angle, C4 is the fourth preset rotation angle, and C5 is the fifth preset rotation angle, which can be set according to actual conditions, and are not specifically limited herein. By setting the rotation angle of the door, the problem of loose door that is prone to oxygen leakage can be solved, and the quality of products in the furnace is ensured.

[0095] S140: Control the movement state of the first motor according to the rotation angle of the door, and complete the closing of the door.

[0096] In order to prevent energy waste, in some embodiments of the present application, when the movement state of the first motor is controlled according to the angle to be rotated of the furnace door, specifically:

[0097] The allowed closing time length of the furnace door is determined;

[0098] The rotation speed of the first motor is determined according to the allowed closing time length of the furnace door and the angle to be rotated of the furnace door;

[0099] The movement state of the first motor is controlled based on the rotation speed of the first motor.

[0100] In the embodiment, the allowed closing time length of the furnace door can be set according to actual conditions, and the furnace door can be closed within this allowed closing time length. The rotation speed of the first motor is determined according to the allowed closing time length of the furnace door and the angle to be rotated of the furnace door, and the movement state of the first motor is controlled based on the rotation speed of the first motor. The corresponding relationship between the allowed closing time length of the furnace door and the angle to be rotated of the furnace door can be tested in advance. By controlling the rotation speed of the first motor, the furnace door can be precisely closed, energy waste can be avoided, and the rotation speed of the first motor can be prevented from being too fast to cause unstable phenomenon of the furnace door.
