Description

Technical Field

[0001] The present application relates to the technical field of laser welding, and in particular to a vacuum laser sealing method, device, equipment and storage medium. Background Art

[0002] The packaging method of the device usually adopts vacuum parallel sealing or laser sealing. Among them, vacuum parallel sealing is resistance welding. Under vacuum conditions, the motor rotates while moving during sealing. Under a certain pressure, the electrodes are intermittently energized. There is contact resistance between the electrode and the cover plate, and between the cover plate and the welding frame. The welding current will generate heat at these two contact resistances, causing the cover plate and the welding frame to form a local molten state, which forms a weld point after solidification.

[0003] The laser welding method uses a laser beam generated by a laser to radiate the surface of the workpiece after expansion, reflection, and focusing. The surface heat diffuses to the inside through heat conduction, causing the local temperature to rise rapidly until it melts to complete the welding.

[0004] In related technologies, vacuum parallel sealing and laser sealing are combined, and vacuum laser sealing is used to package conventional devices. However, when using vacuum laser sealing technology, the laser irradiates the device through a lens. When the laser passes through the lens, the position of the laser irradiating the device will shift, which may cause the sealing to be inadequate and the sealing to fail. Summary of the Invention

[0061] The present application is further described in detail below with reference to the accompanying drawings.

[0062] The present invention provides a vacuum laser welding method that can be performed by an electronic device, which can be a server or a terminal device. The server can be an independent physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud computing services. The terminal device can be a smartphone, a tablet computer, a desktop computer, etc., but is not limited thereto.

[0063] Reference Figure 1 In this embodiment, the vacuum laser sealing system includes a movable laser 1, a vacuum box 2, a lens 3 covered on the vacuum box 2 and a vacuum pump 4 connected to the vacuum box 2 by a pipe, the vacuum pump 4 is electrically connected to an intelligent terminal, the intelligent terminal is electrically connected to the laser 1, an infrared emitter and a gravity sensor are provided in the vacuum box 2, the infrared emitter is electrically connected to the intelligent terminal, a camera 5 is fixedly connected to the laser 1, and the camera 5 is electrically connected to the control terminal.

[0064] In this embodiment, the laser 1 is a 1064 nm laser 1 and the lens 3 is an optical glass that is transparent to 1064 nm.

[0065] like Figure 2 As shown, a vacuum laser sealing method is described, and the main process of the method is described as follows (steps S101 to S104): Step S101, if there is a sealing device in the vacuum box 2, the status information of the sealing device is obtained.

[0066] Specifically, when the staff places the sealing device into the vacuum box 2, the gravity sensor detects that the gravity inside the vacuum box 2 has changed, and it is determined that there is a sealing device in the vacuum box 2. At this time, the status information of the sealing device is obtained, where the status information includes the position information of the sealing device, the placement information in the vacuum box 2 and the placement position of the sealing device.

[0067] Step S102 , obtaining a first sealing angle of the laser 1 , where the first sealing angle is the angle currently formed between the laser 1 and the lens 3 .

[0068] Specifically, since it is necessary to adjust the irradiation angle of the laser 1 before sealing the welding device in order to better seal the welding device, the angle between the laser 1 and the lens 3 is first calculated by manual measurement or angle sensor to obtain the initial angle between the laser 1 and the lens 3.

[0069] Step S103 : adjusting the first sealing angle based on the status information to determine the second sealing angle of the laser 1 .

[0070] Specifically, the first welding point of the sealing device is obtained according to the status information, and the status information includes the welding position of the sealing device; the posture information of the laser 1 is obtained; the first attribute information of the lens 3 is obtained, and the first attribute information includes the refractive index and the propagation speed of the laser emitted by the laser 1 in the lens 3; the second welding point irradiated by the laser 1 is determined based on the posture information and the first attribute information; and the second sealing angle of the laser 1 is adjusted based on the first welding point and the second welding point.

[0071] In this embodiment, the staff places the sealing device in the vacuum box 2, and then obtains the position and placement posture of the sealing device in the vacuum box 2 through the camera 5. Since the sealing device is composed of a cover plate and a shell, the cover plate and the shell need to be laser welded together to achieve sealing of the cover plate and the shell. The first welding point of the sealing device is obtained through the camera 5, and then the sealing device is sealed according to the position of the first welding point, where the first welding point is the position where the sealing device needs to be sealed.

[0072] Laser is a type of light. When light propagates from one medium to another, the laser is affected by the refraction of light, which will cause the position where the laser irradiates on the sealing component to shift. The laser 1 is set in the air. The laser emitted by the laser 1 passes through the air, lens 3, and vacuum in turn before it can illuminate the sealing component. At this time, due to the different refractive indices of the air, lens 3, and vacuum, the position where the laser 1 irradiates the sealing component is different. It is necessary to correct the irradiation position of the laser 1 to achieve the purpose of precise sealing.

[0073] Reference Figure 3The first sealing angle formed between the laser 1 and the surface of the lens 3 is θ1, and the propagation speed of the laser in the air is V1; the refraction angle of the laser entering the lens 3 from the air is θ2, and the propagation speed of the laser in the lens 3 is V2; the refraction angle of the laser entering the vacuum box 2 from the lens 3 is θ3, and the propagation speed of the laser in the vacuum box 2 is V3.

[0074]

[0075] The refraction angle θ3 of the laser light entering the vacuum box 2 from the lens 3 can be calculated by the above formula, where: is the refractive index of lens 3.

[0076] When it is necessary to obtain the first sealing angle θ1 formed between the laser 1 and the surface of the lens 3, it is necessary to obtain the posture information of the laser 1, and then obtain the incident angle of the laser 1 irradiating the surface of the lens 3, that is, the first sealing angle θ1, based on the posture information of the laser 1.

[0077] When laser 1 irradiates the laser on the sealing device, the position where the laser irradiates the sealing device is the second welding point. When welding the sealing device, the second welding point needs to coincide with the first welding point. Only when the second welding point coincides with the first welding point can the sealing device be sealed.

[0078] In this embodiment, by changing the posture of the laser 1, the first sealing angle θ1 formed by the laser 1 and the lens 3 can be changed, that is, the angle of the laser 1 is changed so that the second welding point coincides with the first welding point, thereby achieving the purpose of sealing.

[0079] Furthermore, before determining the second welding point irradiated by the laser 1 based on the posture information and the first attribute information, it also specifically includes obtaining the second attribute information of the sealing device, the second attribute information including the material of the sealing device; obtaining the pressure level of the sealing device based on the second attribute information; determining the first vacuum degree of the vacuum box 2 based on the pressure level; and determining the second welding point irradiated by the laser 1 based on the first vacuum degree, the posture information and the first attribute information.

[0080] In this embodiment, since different sealing components can withstand different atmospheric pressures, and the vacuum level in the vacuum box 2 is affected by the vacuum pump 4, the different vacuum levels will affect the propagation speed of the laser and the angle at which the laser enters the vacuum box 2 through the lens 3, thereby affecting the effect of laser sealing. For example, when the sealing component is made of quartz material, the quartz material can be in an absolute vacuum environment at the lowest. However, due to the characteristics of the vacuum pump 4 itself and the sealing performance of the vacuum box 2 itself, it may be impossible to achieve an absolute vacuum environment in the vacuum box 2. In this case, it is necessary to obtain the first vacuum level in the vacuum box 2 in real time, and determine the second welding point irradiated on the sealing component based on the current first vacuum level, the posture information of the laser 1, and the first attribute information of the lens 3, so that the second welding point and the first welding point coincide with each other and the sealing component is accurately sealed.

[0081] Furthermore, a vacuum degree comparison table of the sealing device is constructed based on the second attribute information and the first vacuum degree; before each sealing of the sealing device, a search is performed based on the vacuum degree comparison table of the sealing device to determine whether there is a second vacuum degree corresponding to the sealing device; if so, the vacuum box 2 is operated using the second vacuum degree; if not, the first vacuum degree is determined according to the second attribute information, and the second attribute information and the first vacuum degree are added to the vacuum degree comparison table of the sealing device.

[0082] In this embodiment, a vacuum sealing system can be used to seal different sealing components. Therefore, it is necessary to adjust the vacuum degree of the vacuum box 2 to different levels according to the different sealing components to achieve the best sealing effect. When sealing a large number of sealing components, a vacuum degree comparison table can be constructed based on the second attribute information of the sealing components and the first vacuum degree corresponding to the sealing components. When sealing components with the same attribute information are sealed, the corresponding second vacuum degree can be obtained from the vacuum degree comparison table, and the vacuum pump 4 can be controlled to operate the vacuum box 2 based on the second vacuum degree.

[0083] When the second vacuum degree corresponding to the current sealing device does not exist in the vacuum degree comparison table, it is necessary to determine the first vacuum degree based on the second attribute information of the sealing device, and add the second attribute information of the current sealing device and the corresponding first vacuum degree to the vacuum degree comparison table. While continuously sealing the sealing device, the vacuum degree comparison table is improved and supplemented, making the subsequent sealing of the sealing device more convenient and quick.

[0084] Furthermore, a sealing model is established based on the first welding point and the state information; a moving path of the infrared ray is determined based on the first welding point in the sealing model; and the moving path is used as the sealing path of the laser 1 .

[0085] When the humidity in the vacuum box 2 is high, the vacuum box 2 is evacuated, and water droplets will be adsorbed in the lens 3, affecting the shooting effect of the camera 5, thereby affecting the sealing effect of the laser 1 on the sealing device. Therefore, a sealing model is established according to the status information of the first welding point and the sealing device, and then the infrared ray emitted by the infrared transmitter moves along the first welding point on the sealing device to determine the moving path of the infrared ray, and the moving path of the infrared ray is displayed on the display device. Then, the moving path of the infrared ray is used as the sealing path of the laser 1. By simulating the sealing path of the laser 1 on the sealing model, it can be ensured that the sealing device can be accurately welded when the field of view of the sealing device is lost.

[0086] In this embodiment, the number of sealing components is obtained; the position information of the laser 1 is obtained; if the number of sealing components is greater than one, the sealing components are sorted based on the status information and the position information to obtain a first sorting result; a second characteristic image of the sealing components is obtained based on the first sorting result; based on the second characteristic image, it is determined whether all sealing components have weld marks; if so, the sealing components with weld marks are deleted from the position of the first sorting result, and the sealing components are re-sorted to obtain a second sorting result, so that the laser 1 seals the sealing components according to the second sorting result.

[0087] Specifically, when sealing the welding devices in the vacuum box 2, the sealing welding devices are sorted according to the number of sealing welding devices and the position information of the laser 1. The proximity principle is adopted, and the position of the current laser 1 irradiation is used as the origin. The straight-line distance from the center of the sealing welding device to the origin is compared. The sealing welding device with the shortest straight-line distance is the first, and the order is downward until all the sealing welding devices are sorted to obtain a first sorting result. Then, the first feature image of all the sealing welding devices is obtained according to the first sorting result, and the first feature of the first feature image is extracted. According to the first feature, it is judged whether there is a weld mark on the first welding point of the sealing welding device. When there is a weld mark, it indicates that the sealing welding device has been sealed. The serial number represented by the sealing welding device with the weld mark can be deleted in the first sorting result, and then the adjusted sealing welding devices are re-sorted to obtain a second sorting result. The sealing welding devices are sealed according to the second sorting result to improve the sealing efficiency.

[0088] Reference Figure 4 If the number of sealed solder components is five, namely, sealed solder component A, sealed solder component B, sealed solder component C, sealed solder component D and sealed solder component E, and the irradiation point of laser 1 is close to sealed solder component A, then the first sorting result can be ABCDE. If the sealed solder component C has been sealed at this time, then the second sorting result is ABDE.

[0089] Step S104 , sealing the sealing component based on a second sealing angle.

[0090] In this embodiment, the sealing component needs to be sealed according to the second sealing angle, the sealing path and the second sorting result, so as to achieve accurate and rapid sealing of the sealing component.

[0091] Furthermore, a second characteristic image of the sealing device is obtained; the second characteristic of the sealing device is extracted, and based on the second characteristic and the preset characteristic, it is determined whether the sealing device is qualified; if not, the sealing device is re-sealed.

[0092] Specifically, after using the vacuum laser sealing system to seal the sealing device, it is necessary to automatically determine whether the sealing device is qualified. At this time, it is necessary to obtain the second feature image of the sealing device, extract the second feature of the second feature image through the image recognition model, and then compare the second feature with the preset feature. When the second feature is consistent with the preset feature, it is determined that the sealing device is qualified. When the second feature is inconsistent with the preset feature, it is determined that the sealing device is unqualified. At this time, the sealing device needs to be re-sealed and corrected to ensure the sealing effect of the sealing device.
