DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to 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, including: a main body bracket 1 and a laser welding machine 2; a rotating disk 3 that rotates 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 with a rotating motor 23. The output shaft of the rotating motor 23 is coaxially fixedly connected with a driving disk, and the driving disk is provided with driving teeth that cooperate with the rotating disk 3. The rotating disk 3 is driven to rotate by driving the driving disk through the rotating motor 23.

[0034] The main body bracket 1 is rotatably connected with a plurality of clamping wheels 25, and the plurality of clamping wheels 25 cooperate with the driving disk of the output shaft of the rotating motor 23 to limit the rotating disk 3 to rotate around its own axis. The cooperation between the driving disk of the output shaft of the rotating motor 23 and the clamping wheels 25 can improve the stability of the rotating disk 3 during rotation.

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

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

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

[0038] The driving component includes: a first mechanical pump 6 and a second mechanical pump 7 fixedly arranged on the bracket main 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, and 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 cross beams 11, each cross beam 11 is fixedly connected with a lifting cylinder 12, the telescopic rod of the lifting cylinder 12 is fixedly connected with the sealing cover 4, and a high-vacuum pipeline 13 is arranged inside the cross beam 11. One end of the high-vacuum pipeline 13 is communicated with the diffusion pump 8, and the other end is communicated with the inside of the vacuum space through a vacuum extraction valve 14.

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

[0041] After the sealing cover 4 descends, two vacuum extractions are required. First, the second mechanical pump 7 drives the vacuum space to form a low vacuum through the vacuum extraction valve 14, and then the first mechanical pump 6 and the diffusion pump 8 cooperate to form a high vacuum (less than 3X10 -3 Pa) under the action of the vacuum extraction valve 14.

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

[0043] The positioning block 17 is provided with a positioning groove. The opening of the positioning groove faces upward and gradually contracts from the outside to the inside. The adsorption block 16 is an electromagnet. After the electromagnet is energized, it cooperates with the positioning groove and adsorbs the cup cover.

[0044] After the cup cover is adsorbed, the pressing cylinder 15 ascends to the initial position, the robotic arm returns to the initial position to pick up a new cup cover, the driving turntable 3 rotates, and another robotic arm drives the cup body 26 into the processing station 301.

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

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

[0047] The heater 5 drives the cup body 26 and the vacuum space for heat treatment;

[0048] Each processing station 301 is provided with a rotating assembly, which is arranged in the vacuum space and cooperates with the laser welding machine 2 to drive the cup body 26 and the cup cover to rotate during laser welding.

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

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

[0051] Each station of the rotating disk 3 is fixedly connected with a sealing component, and the sealing component seals the bottom of the sealing cover 4.

[0052] The sealing component 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, and the annular positioning plate 18 can be locked on the processing station 301 through a bayonet or screws.

[0053] A buffer groove is arranged inside the annular positioning plate 18. A buffer plate 19 matched with the sealing cover 4 is arranged in the buffer groove. A sealing ring 20 is fixedly connected to the upper surface of the buffer plate 19. 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 rings 20 are all directly attached to the bottom of the sealing cover 4. Although this attachment method is simple and the cost is relatively low, the sealing is relatively single in the subsequent processing. Only one surface is sealed, which may cause a gap between the sealing ring 20 and the sealing cover 4, resulting in a 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). When a gap appears on one surface, the other two surfaces can still continue to seal.

[0055] A plurality of guide posts 21 penetrating to the lower surface of the rotating disk 3 are fixedly connected to the bottom of the buffer plate 19. The guide posts 21 mainly play a guiding role when the sealing cover 4 drives the buffer plate 19 to move downward, reducing the situation of jamming during the downward movement of the buffer plate 19.

[0056] Both the buffer groove and the sealing groove gradually contract from the outside to the inside. The gradually contracting structure is more convenient for the sealing cover 4 to be in place. And sealing protrusions 201 matched with the sealing cover 4 are arranged on the inner surfaces of the buffer groove and the sealing groove. During the downward movement of the sealing cover 4, the two protrusions 201 will cooperate with each other, 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, during the downward movement of the buffer plate 19, the sealing ring 20 will be deformed and finally wrap the sealing cover 4. 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] Embodiment 2:

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

[0060] S1: The robotic arm drives the cup lid into the sealing cover 4 and raises the cup lid by driving the lifting cylinder 12;

[0061] S2: Load the cup body 26, and at the same time, the sealing cover 4 moves downward and evacuates, and reaches a high vacuum environment (less than 3X10-3Pa) through vacuum switching;

[0062] S3; During the evacuation process, the heater 5 starts to heat, 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 torch needs to judge the position before welding the cup and drive the welding point of the welding torch to be adjusted according to the position judgment situation;

[0064] Among them, the position judgment drives the data input and calculates the deviation according to the data, and adjusts according to the calculation result.

[0065] The 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] Among them, 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 joint of the cup body 26 and the cup lid is located on the plane Z = Hcup, where Hcup is the height of the cup body 26.

[0071] The welding point of the welding torch is located on the circumference of the joint of the cup body 26 and the cup lid, and its polar coordinates are expressed as (R, θ), where:

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

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

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

[0075] Calculate the X(t), Y(t), 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 collected rotation angle;

[0078] The reference position (X 0 , Y 0 , Z 0 )(reference position without adjustment);

[0079] Calculate the deviation according to the values: ΔX = X(t) - X 0 , ΔY = Y(t) - Y 0 , ΔZ = Z(t) - Z 0 ;

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

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

[0082] For example:

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

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

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

[0086] Trigger condition:

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

[0088] If |ΔY| > Y_threshold, trigger the Y-direction adjustment.

[0089] If |ΔZ| > Z_threshold, trigger the Z-direction adjustment.

[0090] To avoid system instability caused by too large adjustment amplitude, a maximum adjustment amplitude limit is introduced. The maximum adjustment amplitude:

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

[0092] Adjustment Y = 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 function of the clip function is to limit the adjustment amount within the specified range. For example, if Adjustment x exceeds X max it is clipped to X max .

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

[0096] Abnormal situation judgment:

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

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

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

[0100] Among them, i can be any one of the directions X, Y, Z.

[0101] S4: Adjust the position of the welding torch of the laser welding machine 2. The pressing cylinder 15 drives the cup lid to drop, the rotating assembly drives the cup body 26 and the cup lid to rotate, the welding torch welds the cup body 26 and the cup lid, and after welding, the heater 5 stops heating;

[0102] Among them, the cup body 26 and the cup lid need to be welded in a vacuum state so that the material does not oxidize. The interlayer between the inner and outer shells of the thermos cup needs to be vacuum - sealed intact to ensure the heat - preservation characteristics of the thermos cup. The higher the vacuum degree, the better the heat - preservation effect.

[0103] Therefore, since the seal cover 4 needs to be evacuated, two high-temperature pressure sensors are provided inside the seal cover 4. One is set at the top of the seal cover 4, and the other is set in the area of the seal cover 4 near the sealing ring 20. It is determined whether the seal cover 4 is damaged or the sealing ring 20 is damaged through the two pressure sensors.

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

[0105] Damage to the seal cover 4: The leakage point is located in the seal cover 4. The pressure of sensor B will drop rapidly, while the pressure of the sensor near the sealing ring 20 (sensor A) drops slowly because the sealing ring 20 is not damaged.

[0106] However, the drop rate of sensor B may be faster or the difference between the two is smaller.

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

[0108] Differential pressure judgment:

[0109] ΔP(t) = P A (t) - P B (t);

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

[0111] The pressure P of the sensor A near the sealing ring 20 A (t) drops rapidly.

[0112] The pressure P of the sensor B at the top of the seal cover 4 B (t) drops slowly.

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

[0114] The pressure P of the sensor B at the top of the seal cover 4 B (t) drops rapidly.

[0115] The pressure P of the sensor A near the sealing ring 20 A (t) drops slowly.

[0116] If ∣ΔP(t)∣ ≤ ΔPth and the pressures of both sensors drop, it may be that the seal cover 4 is damaged far from the sealing ring 20.

[0117] If |ΔP(t)| = ΔPth and the pressures of both sensors decrease, the leakage point 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 seal ring leakage, seal cover damage), record sensor data, and adjust the threshold to improve the accuracy.

[0119] Judge whether the seal cover 4 or the seal ring 20 needs to be replaced according to the above situation. Therefore, through the comprehensive judgment of the pressure difference and the pressure change trend, false alarms are reduced, and the faulty component (seal ring 20 or seal cover 4) is clearly pointed out, which is convenient for quick repair.

[0120] S5: Drive the gas in the seal cover 4 to cool to one atmosphere, and drive the welded cup body 26 to disengage from the processing station 301, and drive different cup bodies 26 and cup lids for welding in this way.

[0121] Among them, during the rotation of the rotating disk 3, the processing states of multiple stations are different, so as to ensure that after the cup body 26 in one station is welded, the subsequent cup body 26 can be continuously welded after rotating 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 a limitation on the protection scope of the present invention. Any simple modification or equivalent replacement of the technical solution of the present invention by those of ordinary skill in the art does not depart from the essence and scope of the technical solution of the present invention.
