Description

Technical Field

[0001] The invention relates to the technical field of laser welding, and in particular to an automatic welding device for a metal thermos cup. Background Art

[0002] Metal thermos cups are usually made of metal materials on both the inside and outside. In the manufacturing process, welding is a very critical link. Welding can not only firmly connect the inner liner and the outer shell to form a complete container, but also significantly improve the sealing and durability of the thermos cup.

[0003] At present, the inner liner and outer shell of thermos bottles are mostly connected by laser welding technology. The laser welding device irradiates the seam between the inner liner and the outer shell with a laser beam to melt the material at the seam. When the laser beam moves out of this area, the material at the seam cools and forms to achieve a firm connection between the two. However, when the existing laser welding device processes the inner liner and outer shell of thermos bottles with different diameters, it is necessary to adjust the parameters of the welding device (such as welding position, etc.) for each diameter of the thermos bottle. This results in extra time required for equipment debugging each time the product model is changed. This not only increases the production preparation time, but also reduces the overall welding efficiency and affects the production line's capacity. Summary of the invention

DETAILED DESCRIPTION

[0054] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0055] The present invention adopts a method of real-time detection of the inner liner and the outer shell of the thermos cup, so that the laser welding device can adjust the welding parameters of the welding parts of the inner liner and the outer shell of the thermos cup in real time. In the process of welding the inner liner and the outer shell of the thermos cup, the detection part not only plays a detection effect, but also can fix the inner liner and the outer shell of the thermos cup to prevent the inner liner and the outer shell of the thermos cup from being offset during the welding process.

[0056] Embodiment 1: An automatic welding device for a metal thermos cup, such as Figure 1-Figure 6 As shown, it includes a workbench 1; a slide rail 2, which is fixed to the workbench 1, the slide rail 2 is slidably connected to a sliding member 3, the sliding member 3 is fixed to a supporting plate 4, the workbench 1 is fixed to an L-shaped plate 5, the L-shaped plate 5 is fixed to a first driving member 6, and the telescopic end of the first driving member 6 has a first connecting frame 7; a fixed shell 8, which is fixed to the first connecting frame 7; a telescopic frame 9, which is fixed to the fixed shell 8; a laser welding component 10, which is arranged at the telescopic part of the telescopic frame 9; a detection component, which is arranged in the fixed shell 8, and is used to measure the thickness of the outer liner 101 and the inner liner 102; an adjustment component, which is arranged in the fixed shell 8, and is used to adjust the position of the laser welding component 10, and the thickness of the outer liner 101 and the inner liner 102 are measured by the detection component, and the laser welding component 10 is adjusted in cooperation with the adjustment component, so that the laser welding component 10 is suitable for outer liner 101 and inner liner 102 with different diameters.

[0057] In the above scheme, the outer liner 101 and the inner liner 102 in the figure are the outer shell and the inner liner of the existing thermos cup, the slide rail 2 is slidably connected with an electric slider, the electric slider in the slide rail 2 is rotatably connected with the slide member 3, the slide member 3 is composed of a cylinder fixed to each other and two L-shaped frames. In actual use, the staff can adjust the number of the slide member 3 and the electric slider in the slide rail 2 according to actual conditions, the fixed shell 8 is fixed and connected with a connecting pipe for extracting the exhaust gas generated by welding in the fixed shell 8, the first driving member 6 is an electric push rod, the laser welding member 10 is used to generate a laser beam, and the laser The welding part 10 is located in the fixed shell 8 to ensure the stability of the laser welding part 10 during the welding process and to ensure the cleanliness of the welding environment. The thickness of the outer liner tube 101 and the inner liner tube 102 is measured by the detection component to obtain the middle part of the upper joint of the outer liner tube 101 and the inner liner tube 102 (the middle part of the joint is the position to be welded. The outer liner tube 101 and the inner liner tube 102 to be welded in the present invention have the same wall thickness and height). In this way, the adjustment component is used to adjust the laser welding part 10 to achieve adaptive welding of the outer liner tube 101 and the inner liner tube 102.

[0058] like Figure 5 and Figure 6 As shown, the detection component includes: a connecting rod 20, fixed in the fixed shell 8; a fixed seat 21, fixed to the end of the connecting rod 20 and located in the fixed shell 8; L-shaped rods 22 distributed at intervals, all limitedly slidably connected to the fixed seat 21, the L-shaped rods 22 limitedly slidably connected to symmetrically distributed extrusion blocks 23, the detection component also includes: first elastic telescopic rods 24, the number of which is the same as the L-shaped rods 22, respectively fixed to adjacent L-shaped rods 22, a first hinged rod 25 is hinged between the extrusion block 23 and the adjacent first elastic telescopic rod 24, the adjacent and symmetrically distributed extrusion blocks 23 are all provided with inclined surfaces for extruding the outer liner 101 and the inner liner 102, and the opposite sides of the adjacent and symmetrically distributed extrusion blocks 23 are rotatably connected with balls.

[0059] In the above scheme, there are three L-shaped rods 22 distributed in a circular array (three in the present invention is only for example and not limitation), and a gap is left between two adjacent extrusion blocks 23. The base position of the L-shaped rods 22 distributed in the circular array is close to the axis of the fixed seat 21. When the sum of the thickness of the outer liner 101 and the inner liner 102 is greater than the thickness of the gap between the two adjacent extrusion blocks 23, the two adjacent extrusion blocks 23 will move at the same time, so as to fix the outer liner 101 and the inner liner 102 of different thicknesses. The inclined surface of the extrusion block 23 is used to guide the outer liner 101 or the inner liner 102, and the ball on the extrusion block 23 is used to prevent the outer liner 101 or the inner liner 102 from hard friction with the extrusion block 23.

[0060] like Figure 5 and Figure 6As shown, the adjustment assembly includes: an articulated seat 30, which is slidably connected to the connecting rod 20, a second articulated rod 31 is hinged between the L-shaped rod 22 and the articulated seat 30, and a first spring is arranged between the articulated seat 30 and the fixed seat 21; a second connecting frame 32, which is slidably connected to the fixed seat 21, a third articulated rod 311 is hinged between the second connecting frame 32 and the articulated seat 30, and the side of the second connecting frame 32 away from the articulated seat 30 is fixedly connected to the telescopic part of the telescopic frame 9.

[0061] In the above solution, the right side of the second connecting frame 32 is fixedly connected to the telescopic portion of the telescopic frame 9. When the second connecting frame 32 adjusts its position, the telescopic frame 9 drives the laser welding part 10 to adjust the welding position.

[0062] Working principle: Before welding the outer liner 101 and the inner liner 102, the staff first places the external drive device in the middle of the inner rear side of the slide rail 2, so that the external drive device can drive the outer liner 101 and the inner liner 102 and their accessories to rotate through the sliding part 3, thereby completing the preparation actions before welding.

[0063] When it is necessary to weld the outer liner 101 and the inner liner 102, the staff will place the inner liner 102 and the outer liner 101 on the upper side of the support plate 4 respectively (after the two are placed, the inner liner 102 is located inside the outer liner 101). During this process, the outer liner 101 and the inner liner 102 can be fixed by an external fixing device, and the sliding member 3 drives the support plate 4, the inner liner 102 and the outer liner 101 to move directly below the first driving member 6. When the above-mentioned parts move until the axis of the sliding member 3 coincides with the axis of the fixed shell 8, the sliding member 3 stops moving, and the outer side of the sliding member 3 is connected to the external driving device. At this time, the liner 102 and the outer liner 101 are located directly below the fixed shell 8.

[0064] When the inner liner tube 102 and the outer liner tube 101 are located directly below the fixed shell 8, the telescopic end of the first driving member 6 drives the parts in the fixed shell 8 to move downward through the first connecting frame 7. Taking the movement process of two extrusion blocks 23 as an example, the two extrusion blocks 23 move with the fixed shell 8 and the fixed seat 21 until the inclined surface of the outer extrusion block 23 contacts the outer side of the outer liner tube 101 or the inclined surface of the inner extrusion block 23 contacts the inner side of the inner liner tube 102. Under the action of the outer liner tube 101 or the inner liner tube 102 squeezing the inclined surface of the adjacent extrusion block 23, the two extrusion blocks 23 are moved downward. The movable L-shaped rod 22 slides on the fixed seat 21. During the sliding of the L-shaped rod 22, the adjacent second hinged rod 31 drives the hinged seat 30 to move (the adjacent first spring contracts during the movement of the hinged seat 30). Through the movement of the hinged seat 30, the remaining second hinged rod 31 drives the L-shaped rod 22 to move synchronously, and the third hinged rod 311 drives the second connecting frame 32 to move. During the movement of the second connecting frame 32, the telescopic part of the telescopic frame 9 is driven to move. When the telescopic part of the telescopic frame 9 moves, the welding position of the laser welded part 10 is changed.

[0065] When the two adjacent extrusion blocks 23 move along with the fixed shell 8 and the fixed seat 21 to the point where the balls on the opposite sides of the two extrusion blocks 23 contact the outer side of the outer liner tube 101 and the inner side of the inner liner tube 102 respectively, the two extrusion blocks 23 then only slide downward. At this time, the welding position of the laser welded part 10 has been fixed, and the laser welded part 10 is facing the joint between the outer liner tube 101 and the inner liner tube 102. Through the above operation, the welding position of the laser welded part 10 on the outer liner tube 101 and the inner liner tube 102 is changed in real time, thereby achieving the effect of adjusting the welding position of the laser welded part 10 in real time according to the outer diameter of the outer liner tube 101 and the inner diameter of the inner liner tube 102.

[0066] When the two adjacent extrusion blocks 23 are moved along with the fixed shell 8 and the fixed seat 21 to the point where the balls on the opposite sides of the two extrusion blocks 23 respectively contact the outer side of the outer liner 101 and the inner side of the inner liner 102 and move to the required working position, the first drive member 6 stops working. At this time, the fixed shell 8 covers the upper side of the outer liner 101 and the inner liner 102, and the laser welding part 10 faces the joint of the outer liner 101 and the inner liner 102. At this time, the sliding member 3 is driven to rotate by an external driving device, and the sliding member 3 drives the outer liner 101 and the inner liner 102 to rotate by the support plate 4. During the rotation of the outer liner 101 and the inner liner 102, the adjacent extrusion blocks 23 are The ball rotates, and the limit provided by the ball and the extrusion block 23 allows the outer liner 101 and the inner liner 102 to remain stable during the welding process. During the rotation of the outer liner 101 and the inner liner 102, the laser welding part 10 welds the joint between the outer liner 101 and the inner liner 102 (when the thickness of the outer liner 101 and the inner liner 102 is greater than the distance between the two adjacent extrusion blocks 23, the two adjacent extrusion blocks 23 move away from each other, and during the movement of the extrusion block 23, the telescopic part of the adjacent first elastic telescopic rod 24 is driven downward by the adjacent first hinged rod 25, so as to adaptively fix the outer liner 101 and the inner liner 102 of different thicknesses).

[0067] During the welding process of the outer liner 101 and the inner liner 102, the welding part is covered by the fixed shell 8 to keep the welding environment stable, ensure the cleanliness of the welding environment, and help concentrate and maintain the heat in the welding area.

[0068] After the sliding member 3 drives the supporting plate 4 to rotate one circle, the external driving device stops working, thereby completing the welding of the outer liner 101 and the inner liner 102. At this time, the laser welding part 10 no longer works, and then the telescopic end of the first driving member 6 drives the fixed shell 8 and its accessory parts to move upward and reset through the first connecting frame 7, so that the balls on all the extrusion blocks 23 gradually break away from the contact with the outer liner 101 or the inner liner 102.

[0069] After the balls on all the extrusion blocks 23 are out of contact with the outer liner 101 or the inner liner 102, the articulated seat 30 moves and resets under the action of the first spring, so that all the second articulated rods 31 drive all the L-shaped rods 22, and the third connecting frame 311 drives the second connecting frame 32 to move and reset, thereby restoring the position before welding (after the balls on the extrusion blocks 23 are no longer in contact with the outer liner 101 or the inner liner 102, the telescopic part of the first elastic telescopic rod 24 drives the adjacent extrusion blocks 23 to move and reset through the adjacent first articulated rod 25).

[0070] After the welding of the outer liner 101 and the inner liner 102 is completed, the electric slider of the slide rail 2 drives the support plate 4, the outer liner 101 and the inner liner 102 to move through the sliding part 3, and then the staff can remove the outer liner 101 and the inner liner 102.

[0071] In Example 1, the sliding member 3 is rotationally connected to the electric slider on the lower side, while in Example 2, the sliding member 3 is fixed to the electric slider on the lower side. In Example 1, the sliding member 3 is directly driven by an external driving device, while in Example 2, a motor is fixed to the middle part of the inner rear side of the slide rail 2, the driving shaft of the motor of the slide rail 2 is fixed to a transmission gear, and the lower side of the second elastic telescopic rod 50 is fixed to a driven gear.

[0072] Embodiment 2: Based on embodiment 1, Figure 4 and Figure 7-Figure 10 As shown, it also includes: a first fixing component, which is arranged on the sliding member 3 and is used to fix the inner liner tube 102. The first fixing component includes: a second elastic telescopic rod 50, which is rotatably connected to the sliding member 3; a rotating disk 51, which is limitedly rotatably connected to the sliding member 3; a sliding disk 52, which is splined to the rotating disk 51 and fixedly connected to the telescopic end of the second elastic telescopic rod 50, and the sliding disk 52 is slidably connected to the first clamping blocks 53 distributed at intervals, and a second spring is arranged between the first clamping blocks 53 and the sliding disk 52, and the first clamping blocks 53 distributed at intervals are all used to fix the inner liner tube 102.

[0073] In the above scheme, the fixed part of the second elastic telescopic rod 50 is fixedly connected to the sliding member 3, and the opposite sides of the first clamping blocks 53 distributed at intervals are provided with arc surfaces, and the arc surfaces of the first clamping blocks 53 distributed at intervals are located in the same annular surface. The inner liner tube 102 is fixed and released by moving all the first clamping blocks 53. All the first clamping blocks 53 are initially located on one side close to the axis of the sliding disk 52. Fig.10 In the embodiment, the first clamping block 53 is in a gathered state on the sliding plate 52, and the second spring on the first clamping block 53 is in a compressed state.

[0074] like Figure 8-Figure 10 As shown, the first fixing assembly further includes: a sliding ring 55 slidably connected to the telescopic portion of the second elastic telescopic rod 50 , and a fourth hinged rod 54 is hinged between the first clamping block 53 and the sliding ring 55 .

[0075] In the above solution, the sliding ring 55 drives all the first clamping blocks 53 to move synchronously through all the fourth hinge rods 54 on the adjacent sliding plates 52, thereby achieving the approach and separation of all the first clamping blocks 53 on the sliding plates 52.

[0076] like Figure 8-Figure 10As shown, it also includes: a second fixing component, which is arranged on the sliding disk 52 and is used to fix the outer liner 101. The second fixing component includes: fixed blocks 60 distributed at intervals, all fixed to the sliding disk 52; second clamping blocks 61, the number of which is consistent with that of the fixed blocks 60, all slidably connected to the rotating disk 51, the second clamping blocks 61 are fitted with adjacent fixed blocks 60, a third spring is arranged between the second clamping block 61 and the rotating disk 51, and the second clamping block 61 is fixed with an elastic member 62, and the elastic member 62 is used to fix the outer liner 101.

[0077] In the above scheme, the spaced fixed blocks 60 are located on the outside of the spaced first clamping blocks 53, and the distance between the spaced fixed blocks 60 and the axis of the sliding disk 52 is greater than the distance between the axis of the spaced first clamping blocks 53 and the axis of the sliding disk 52. When the spaced first clamping blocks 53 are in contact with the outer liner 101, the spaced fixed blocks 60 will not affect the fixation of the outer liner 101. In the present invention, the elastic member 62 is an elastic airbag.

[0078] like Figure 2 , Figure 4 , Figure 7 and Figure 8 As shown, it also includes: an adjustment component, which is arranged on the telescopic part of the second elastic telescopic rod 50, and is used to adjust the position between the outer liner 101 and the inner liner 102. The adjustment component includes: a second rotating shell 70, which is limitedly rotated and connected to the telescopic part of the second elastic telescopic rod 50, and the second rotating shell 70 is slidably connected to the sliding member 3 through a sliding frame; a sliding rod 71, which is slidably connected to the second rotating shell 70, and a fourth spring is arranged between the sliding rod 71 and the second rotating shell 70; a sliding groove 72, which is arranged on the L-shaped plate 5, and the sliding groove 72 is used to guide the sliding rod 71. The sliding groove 72 is composed of two transverse grooves and one oblique groove. The two transverse grooves in the sliding groove 72 are not on the same horizontal line. The oblique groove in the sliding groove 72 is located between the two transverse grooves. A trapezoidal groove is arranged on one side of the L-shaped plate 5. The trapezoidal groove on the L-shaped plate 5 is connected to the lower transverse groove in the sliding groove 72, which is used to guide the sliding rod 71.

[0079] In the above solution, the elastic coefficient of the second elastic telescopic rod 50 is smaller than the elastic coefficient of the spring adjacent to the sliding rod 71 , and the fourth spring in the second rotating shell 70 is used to provide a movement margin for the sliding rod 71 .

[0080] Working principle: When it is necessary to weld the outer liner tube 101 and the inner liner tube 102, the staff places the inner liner tube 102 on the upper side of the sliding disk 52. During the placement process, the inner liner tube 102 squeezes the surrounding first clamping blocks 53, so that all the first clamping blocks 53 move backward and squeeze the second spring. During the backward movement of all the first clamping blocks 53, the sliding ring 55 is driven upward by the fourth hinge rod 54, so that all the first clamping blocks 53 can move at the same time. When the lower side of the inner liner tube 102 is in contact with the upper side of the sliding disk 52, all the first clamping blocks 53 apply extrusion force to the inner liner tube 102 under the action of the second spring, thereby fixing the inner liner tube 102.

[0081] After completing the fixation of the inner lining tube 102, the staff puts the outer lining tube 101 on the upper side of the rotating disk 51. At this time, the outer lining tube 101 covers all the second clamping blocks 61 on the adjacent rotating disk 51. Then, the electric slider in the slide rail 2 drives the sliding member 3, the second elastic telescopic rod 50, the rotating disk 51, the outer lining tube 101 and the inner lining tube 102 to move toward the direction of the L-shaped plate 5. In the process of the sliding member 3 driving the second elastic telescopic rod 50 to move, the sliding rod 71 enters the horizontal groove on the left side of the sliding groove 72 from the trapezoidal groove on the left side of the L-shaped plate 5 to guide the sliding rod 71.

[0082] When the sliding member 3 drives the second elastic telescopic rod 50 to move until the sliding rod 71 contacts the inclined groove in the sliding groove 72, the sliding rod 71 drives the second rotating shell 70, the telescopic part of the second elastic telescopic rod 50, the sliding disk 52 and the inner liner tube 102 to move upward through the fourth spring. During the upward movement of the sliding disk 52, it drives all the fixed blocks 60 to squeeze the adjacent second clamping blocks 61 respectively, so that the second clamping blocks 61 drive the adjacent elastic members 62 to move outward (the third spring is squeezed during the movement of the second clamping blocks 61), so that the elastic members 62 are aligned with the inner side of the outer liner tube 101. The outer liner 101 is fixed by the fit, and the sliding plate 52 drives the inner liner 102 to move upward so that the outer side surface of the upper part of the inner liner 102 contacts the inner side surface of the upper part of the outer liner 101, so as to achieve the effect that the inner liner 102 and the outer liner 101 are in contact before welding. Through the pre-contact of the outer liner 101 and the inner liner 102, and in coordination with the subsequent welding, the double fixation of the thermos cup is achieved, so that the outer liner 101 and the inner liner 102 are already fit before being welded, thereby enhancing the structural strength of the outer liner 101 and the inner liner 102 after being welded.

[0083] When the sliding member 3 drives the second elastic telescopic rod 50, the inner lining tube 102, the outer lining tube 101 and their accessory parts to move to the bottom of the first driving member 6, the sliding rod 71 is located on the upper side of the inclined groove in the sliding groove 72. At this time, the driven gear on the lower side of the second elastic telescopic rod 50 has been engaged with the transmission gear of the motor drive shaft on the slide rail 2, and then the measurement, fixation and welding of the inner lining tube 102 and the outer lining tube 101 are realized through the actions of Example 1.

[0084] When the inner liner tube 102 and the outer liner tube 101 are welded, the transmission gear on the motor drive shaft on the slide rail 2 is meshed with the driven gear on the second elastic telescopic rod 50, so that the second elastic telescopic rod 50 drives the rotating disk 51 to rotate on the upper side of the sliding member 3 through the sliding disk 52, so as to realize the self-rotation of the inner liner tube 102 and the outer liner tube 101.

[0085] After the welding of the inner liner tube 102 and the outer liner tube 101 is completed, the electric slider in the slide rail 2 drives the slide member 3 and its accessory parts to move to the right, so that the slide rod 71 moves along the horizontal groove on the right side of the slide groove 72, and all the elastic parts 62 on the rotating disk 51 are still kept in contact with the inner side of the outer liner tube 101. When the electric slider in the slide rail 2 drives the slide member 3 and its accessory parts to move to the right until the slide rod 71 is no longer in contact with the slide groove 72, under the action of the elastic force of the second elastic telescopic rod 50 itself, the telescopic part of the second elastic telescopic rod 50 drives the sliding disk 52 and all the fixed blocks 60 to move and reset, so that the fixed block 60 no longer squeezes the adjacent second clamping block 61. The second clamping block 61 moves and resets under the action of the third spring and drives the adjacent elastic parts 62 to disengage from the inner side of the outer liner tube 101, thereby releasing the fixation of the outer liner tube 101, and then the staff can remove the inner liner tube 102 and the outer liner tube 101.
