[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0033] See also Figures 1-8 The present invention provides a technical solution: a rotary laser sealing furnace for welding the cup body 26 and the cup lid, comprising: a main body bracket 1 and a laser welding machine 2; a rotating disk 3 rotating around its own axis is provided on the upper surface of the main body bracket 1, and the main body bracket 1 is fixedly connected to a rotating motor 23, and the output shaft of the rotating motor 23 is coaxially fixedly connected to a driving disk, and the driving disk is provided with driving teeth that cooperate with the rotating disk 3. The driving disk is driven to rotate by the rotating motor 23, and the rotating disk 3 is driven to rotate by the driving disk.

[0034] The main frame 1 is rotatably connected to a plurality of clamping wheels 25, which cooperate with the drive disc of the output shaft of the rotating motor 23 to limit the rotating disc 3 to rotate around its own axis. The drive disc of the output shaft of the rotating motor 23 cooperates with the clamping wheels 25 to improve the stability of the rotating disc 3 during rotation.

[0035] The rotating disk 3 is provided with a plurality of processing stations 301, which are arranged around the axis of the rotating disk 3. A sealing cover 4 is provided directly above each processing station 301. The sealing cover 4 is made of high-strength and high-transmittance fused quartz glass.

[0036] The sealing cover 4 is equipped with a driving assembly, which drives the sealing cover 4 downward to form a vacuum space between the sealing cover 4 and the processing station 301 for placing the cup body 26 and the cup cover.

[0037] The robotic arm cooperates with the mechanical tooling to drive the cup body 26 and the cup cover into the processing station 301.

[0038] The driving assembly includes: a first mechanical pump 6 and a second mechanical pump 7 fixedly arranged on the bracket body. The first mechanical pump 6 is connected to the bottom of the rotating frame 9 through a diffusion pump 8. The rotating frame 9 rotates synchronously with the rotating disk 3. The top of the rotating frame 9 is connected to the second mechanical pump 7 through a low vacuum pipeline 10.

[0039] The rotating frame 9 is provided with a plurality of beams 11, each beam 11 is fixedly connected to a lifting cylinder 12, the telescopic rod of the lifting cylinder 12 is fixedly connected to the sealing cover 4, and a high vacuum pipeline 13 is provided in the beam 11. One end of the high vacuum pipeline 13 is connected to the diffusion pump 8, and the other end is connected to the inside of the vacuum space through a vacuum exhaust valve 14.

[0040] The low vacuum pipeline 10 is connected to the vacuum exhaust valve 14 through a pipeline, and the vacuum exhaust valve 14 is connected to the vacuum space. The high vacuum pipeline 13 is connected to the vacuum exhaust valve 14 through a pipeline, and the vacuum exhaust valve 14 is connected to the vacuum space.

[0041] After the sealing cover 4 is lowered, it needs to be vacuumed twice. First, the second mechanical pump 7 drives the vacuum space through the vacuum exhaust valve 14 to form a low vacuum. Then, the first mechanical pump 6 cooperates with the diffusion pump 8 to form a high vacuum (less than 3X10 -3 Pa).

[0042] A compression cylinder 15 is fixedly connected to the outer upper surface of the sealing cover 4 , and a telescopic rod of the compression cylinder 15 extends into the sealing cover 4 and is fixedly connected to an adsorption block 16 , and a positioning block 17 that cooperates with the adsorption block 16 is fixedly connected to the cup cover.

[0043] The positioning block 17 is provided with a positioning groove, which opens upward and gradually shrinks from the outside to the inside. The adsorption block 16 adopts an electromagnet, which cooperates with the positioning groove after being energized and adsorbs the cup cover.

[0044] After the cup cover is adsorbed, the pressing cylinder 15 moves upward to the initial position, the robotic arm returns to the initial position to take a new cup cover, drives the rotary disk 3 to rotate, and another robotic arm drives the cup body 26 into the processing station 301.

[0045] Each vacuum space is fixedly connected to a heater 5 . After the cup body 26 is placed therein, the heater 5 is disposed in the accommodation space of the cup body 26 .

[0046] After the cup body 26 is placed in, the lifting cylinder 12 drives the sealing cover 4 downward to form a closed space, and then the first mechanical pump 6 and the second mechanical pump 7 cooperate with the diffusion pump 8 to drive the closed space to form a vacuum space.

[0047] The heater 5 drives the cup body 26 and the vacuum space to perform heating treatment;

[0048] Each processing station 301 is provided with a rotating assembly and is located in a vacuum space. The rotating assembly cooperates with the laser welding machine 2 to drive the cup body 26 and the cup cover to perform laser welding during the rotation process.

[0049] The rotating assembly includes: a driving motor 24 fixedly arranged on the rotating disk 3 (each workstation has one), the output shaft of the driving motor 24 is fixedly connected to a rotating plate, the heater 5 is also fixed in the rotating plate, and the upper surface of the rotating plate is provided with a limiting groove that cooperates with the cup body 26. After the cup body 26 is placed in, it is positioned to reduce the shaking phenomenon of the cup body 26 after it is placed in.

[0050] After the cup body 26 is placed in, the driving motor 24 drives the rotating plate to rotate, the pressing cylinder 15 drives the cup cover downward, and the rotating plate drives the cup body 26 and the cup cover to rotate (a rotary support bearing is connected between the telescopic rod of the pressing cylinder 15 and the adsorption block 16. When the cup cover rotates, the adsorption block 16 also rotates).

[0051] Each station of the rotating disk 3 is fixedly connected to a sealing assembly, which seals the bottom of the sealing cover 4.

[0052] The sealing assembly includes: an annular positioning plate 18 arranged on the processing station 301. The processing station 301 is provided with an assembly groove for placing the annular positioning plate 18. The annular positioning plate 18 can be locked on the processing station 301 by means of a bayonet or screws.

[0053] A buffer groove is provided in the annular positioning plate 18, and a buffer plate 19 is provided in the buffer groove to cooperate with the sealing cover 4. The upper surface of the buffer plate 19 is fixedly connected to the sealing ring 20. The sealing ring 20 adopts an annular sealing ring 20. The annular sealing ring 20 is provided with an annular opening facing the sealing cover 4. The annular opening extends outward along the inside of the buffer groove and gradually expands. The open end of the annular sealing ring 20 is fixedly connected to the annular positioning plate 18.

[0054] The existing sealing ring 20 is directly attached to the bottom of the sealing cover 4. Although this attachment method is simple and relatively low-cost, the sealing is relatively single during subsequent processing. Only one side is sealed, which may cause a gap between the sealing ring 20 and the sealing cover 4, resulting in poor sealing effect of the sealing cover 4. The sealing ring 20 of the present application adopts a three-sided sealing structure (sealing the bottom, inner side wall, and outer side wall of the sealing cover 4). If a gap appears on one side, the other two sides can still continue to seal.

[0055] The bottom of the buffer plate 19 is fixedly connected to a plurality of guide posts 21 that penetrate the lower surface of the rotating disk 3. The guide posts 21 mainly play a guiding role when the sealing cover 4 drives the buffer plate 19 downward, thereby reducing the possibility of the buffer plate 19 getting stuck during the downward process.

[0056] The buffer groove and the sealing groove both shrink gradually from the outside to the inside. The gradually shrinking structure makes it easier for the sealing cover 4 to be put into place, and the inner surfaces of the buffer groove and the sealing groove are provided with sealing protrusions 201 that cooperate with the sealing cover 4. During the downward process of the sealing cover 4, the two protrusions 201 will cooperate with each other to compress the sealing space and drive the sealing ring 20 to fit with the sealing cover 4.

[0057] During the downward movement of the sealing cover 4, since the annular opening of the sealing ring 20 is fixedly connected to the annular positioning plate 18, and the bottom is fixedly connected to the buffer plate 19, the sealing ring 20 will be deformed and eventually wrap the sealing cover 4 during the downward movement of the buffer plate 19. During the downward movement of the sealing cover 4 driving the buffer plate 19, the buffer groove and the sealing protrusion 201 of the sealing groove cooperate with each other to further drive the opening end of the sealing cover 4 to be sealed.

[0058] Example 2:

[0059] A processing method for a rotary laser sealing furnace, comprising:

[0060] S1: The robotic arm drives the cup cover into the sealing cover 4 and drives the cup cover to rise through the lifting cylinder 12;

[0061] S2: The cup body 26 is loaded, and the sealing cover 4 is moved downward and vacuumed, and a high vacuum environment (less than 3×10-3 Pa) is achieved through vacuum switching;

[0062] S3; during the vacuuming process, the heater 5 starts heating, the rotating disk 3 rotates and drives the cup body 26 and the cup lid to be transported to the laser welding machine 2;

[0063] Among them, the welding gun needs to judge the position before welding the cup, and adjust the welding point of the welding gun according to the position judgment;

[0064] Among them, position judgment drives data input and performs deviation calculation based on the data, and makes adjustments based on the calculation results.

[0065] Data input includes:

[0066] The current welding point coordinates of the cup body (X(t), Y(t), Z(t)) (obtained through sensor or robot feedback);

[0067] Here, a three-dimensional rectangular coordinate system is set, where:

[0068] The central axis of the cup body 26 is the Z-axis.

[0069] The center of the bottom surface of the cup body 26 is the origin O(0,0,0).

[0070] The junction of the cup body 26 and the cup cover is located on a plane Z=Hcup, where Hcup is the height of the cup body 26 .

[0071] The welding point of the welding gun is located on the circumference of the junction between the cup body 26 and the cup cover. Its polar coordinates are expressed as (R, θ), where:

[0072] R is the radius of the cup 26 (ie, the radius of the welding circle).

[0073] θ is the rotation angle (the amount of rotation from the initial position).

[0074] At any moment, according to the current rotation angle θ;

[0075] Calculate the X(t), Y(t), and Z(t) coordinates of the real-time welding point:

[0076] X(t)=R*cos(θ(t)); Y(t)=R*sin(θ(t)); Z(t)=Hcup;

[0077] θ(t) is the real-time acquisition rotation angle;

[0078] The welding point reference position of the welding gun (X0, Y0, Z0) (reference position that does not require adjustment);

[0079] Deviation calculation is performed based on the numerical values: ΔX = X(t) - X0, ΔY = Y(t) - Y0, ΔZ = Z(t) - Z0;

[0080] Finally, adjust the direction of the trigger welding gun according to the set threshold.

[0081] Among them, the threshold value is set (according to the welding accuracy requirements);

[0082] For example:

[0083] X_threshold = 0.5 mm (longitudinal deviation);

[0084] Y_threshold = 0.3 mm (lateral deviation);

[0085] Z_threshold = 0.2 mm (height deviation);

[0086] Trigger conditions:

[0087] If |ΔX|>X_threshold, trigger X-direction adjustment.

[0088] If |ΔY|>Y_threshold, Y direction adjustment is triggered.

[0089] If |ΔZ|>Z_threshold, Z direction adjustment is triggered.

[0090] In order to avoid system instability caused by excessive adjustment, a maximum adjustment range limit is introduced. The maximum adjustment range is:

[0091] Adjustment X =clip(Adjustment X ,-X max ,X max );

[0092] AdjustmentY =clip(Adjustment Y ,-Y max ,Y max );

[0093] Adjustment z =clip(Adjustment z ,-Z max ,Z max );

[0094] X max =2mm,Y max =1.5mm,Z max = 1mm. The clip function is used to limit the adjustment amount to a specified range. For example, if Adjustment x More than X max Then crop it to X max .

[0095] Update the new position of the welding gun according to the adjustment amount;

[0096] Abnormal situation judgment:

[0097] If the deviation in one direction exceeds three times the allowable range, an emergency stop is triggered;

[0098] If |Δi|>3×threshold i , triggering an emergency stop.

[0099] Among them, Δi represents the deviation between the actual position of the welding gun in a certain direction (X / Y / Z) and the target position, and threshold i Indicates the allowable deviation threshold of the welding gun in a certain direction (X / Y / Z).

[0100] Here, i can be any direction among X, Y, and Z.

[0101] S4: The welding gun position of the laser welding machine 2 is adjusted, the pressing cylinder 15 drives the cup cover to fall, the rotating assembly drives the cup body 26 and the cup cover to rotate, and the welding gun welds the cup body 26 and the cup cover. After the welding is completed, the heater 5 stops heating;

[0102] Among them, the cup body 26 and the cup cover must be welded under vacuum state, the material will not be oxidized, and the interlayer between the inner and outer shells of the thermos cup needs to be vacuum sealed intact to ensure the thermal insulation properties of the thermos cup. The higher the vacuum degree, the better the thermal insulation effect.

[0103] Therefore, since the sealing cover 4 needs to be vacuumed, two high-temperature pressure sensors are provided inside the sealing cover 4, one is provided at the top of the sealing cover 4, and the other is provided in the area of ​​the sealing cover 4 close to the sealing ring 20. The two pressure sensors are used to determine whether the sealing cover 4 or the sealing ring 20 is damaged.

[0104] The sealing ring 20 is damaged: The leakage point is located at the open end of the sealing cover 4 (near the sealing ring 20). The pressure of the sensor close to the sealing ring 20 (sensor A) will drop rapidly, while the pressure of the top sensor (sensor B) will drop slowly because the sealing cover 4 is not damaged.

[0105] Sealing cover 4 is damaged: The leakage point is located at sealing cover 4, and the pressure of sensor B will drop rapidly, while the pressure of the sensor (sensor A) close to the sealing ring 20 will drop slowly because the sealing ring 20 is not damaged.

[0106] But the rate of decrease of sensor B may be faster or the difference between the two may be smaller.

[0107] Among them, the pressure P of sensor A A (t); Pressure P of sensor B B (t);

[0108] Pressure difference judgment:

[0109] ΔP(t)=P A (t)-P B (t);

[0110] Under normal circumstances, ΔP(t) should be close to 0 (allowing a small error).

[0111] Pressure P of sensor A near sealing ring 20 A (t) Rapidly decline.

[0112] Sensor B pressure P on top of sealing cover 4 B (t) Decreases slowly.

[0113] If |ΔP(t)|>ΔPth (i.e., the pressure difference exceeds the threshold), the sealing ring 20 may be damaged and leaking. (It is also possible that the sealing cover 4 is damaged near the sealing ring 20).

[0114] Sensor B pressure P on top of sealing cover 4 B (t) Rapidly decline.

[0115] Pressure P of sensor A close to seal ring 20 A (t) Decreases slowly.

[0116] If |ΔP(t)|≤ΔPth and the pressures of both sensors decrease, it is possible that the sealing cover 4 is damaged away from the sealing ring 20.

[0117] If |ΔP(t)|=ΔPth, and the pressures of both sensors decrease, the leak may be between sensor A and sensor B.

[0118] Pressure difference threshold: usually 2-3 times the normal pressure fluctuation range; simulate different leakage scenarios (such as sealing ring leakage, sealing cover damage), record sensor data, and adjust the threshold to improve accuracy.

[0119] Based on the above situation, it is judged whether the sealing cover 4 or the sealing ring 20 needs to be replaced. Therefore, a comprehensive judgment is made through the pressure difference and the pressure change trend to reduce false alarms and clearly point out the faulty component (sealing ring 20 or sealing cover 4) for quick maintenance.

[0120] S5: The gas in the sealing cover 4 is driven to cool to an atmospheric pressure, and the welded cup body 26 is driven to separate from the processing station 301, and the welding of different cup bodies 26 and cup covers is driven in this reciprocating manner.

[0121] In the process of rotation of the rotary disk 3, the processing states of the multiple stations are different, so as to ensure that after the welding of the cup body 26 in one station is completed, the subsequent cup body 26 can continue to be welded after it rotates over.

[0122] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Simple modifications or equivalent substitutions of the technical solution of the present invention by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the present invention.
