[0002] In the process of making the inner liner of a round cup, the cup bottom and the cup body need to be welded together. The existing welding method is that the operator buckles the cup body on the cup bottom and then uses a handheld welding gun to complete the welding of the two.

[0003] The existing welding method has low welding efficiency. Operators are prone to put the cup upside down when transferring it, resulting in rework. In addition, manual hands are prone to shaking during welding, which causes the welding gun to shake. The stability of the welding process cannot be guaranteed, which in turn affects the quality of the finished welded product. In addition, the technical ability of the welding master is also required to be high. Utility Model Content

The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0033] The utility model dual laser welding machine is usually used to weld a cup body to the top of a cup bottom, and comprises a cup body conveying assembly 10, a cup body clamping assembly 11 and a welding assembly 12. The cup body conveying assembly 10 is used to convey the cup body and flip the cup body to ensure that the groove of the cup body faces upward; the cup body clamping assembly 11 is used to clamp the flipped cup body and place it on the top of the cup bottom; the welding assembly is used to weld the cup body and the cup bottom together.

[0034] like Figure 4-6 As shown, it is a structural schematic diagram of the cup body conveying assembly 10, which is used to convey the cup body and flip the cup body to ensure that the groove of the cup body faces upward. The cup body conveying assembly 10 includes a cup body conveying frame 101, a cup body rotating plate 102, a limiting groove 103, an inner stop wheel 104, an outer stop wheel 105, an outer stop wheel 106, an inner stop wheel 107, a first carrier plate 108, a second carrier plate 109, a conveying unit, a baffle 1013, an adjustment plate 1014, an adjustment wheel 1015, an adjustment rod 1016, a spring 1017, an anti-slip plate 1018, a gantry 1019, a first lifting plate 1020 and a finger cylinder 1021.

[0035] The cup body conveying rack 101 is fixed on the welding machine by screw fastening. There are two cup body rotating plates 102, which are rotatably arranged above the cup body conveying rack 101 and arranged opposite to each other (a rotating motor connected to the cup body rotating plate 102 is fixed on the top of the cup body conveying rack 101, which is used to drive the cup body rotating plate 102 to rotate, thereby completing the flipping of the cup body, and the rotating motor is not shown in the figure).

[0036] The first carrier plate 108 and the second carrier plate 109 are fixed on the opposite sides of the cup body rotating plate 102, and the first carrier plate 108 and the second carrier plate 109 are perpendicular to each other. The first carrier plate 108 is used to carry the cup body placed horizontally during the conveying process. The servo motor drives the cup body rotating plate 102 to rotate 90° clockwise, and then drives the first carrier plate 108 and the second carrier plate 109 to rotate 90° clockwise, so as to rotate the horizontally placed cup body clockwise by 90° to ensure that the groove of the cup body is set upward.

[0037] The limiting groove 103 is provided on the opposite side of the cup body rotating plate 102, the outer limiting wheel 105 is rotatably mounted on the top of the cup body conveying frame 101 through a bearing seat, and the inner limiting wheel 104 is integrally connected to the inner side of the outer limiting wheel 105 and is coaxially arranged with the outer limiting wheel 105. The outer peripheral surface of the inner limiting wheel 104 abuts against the inner side wall of the limiting groove 103, and the outer limiting wheel 105 abuts against the outer side of the cup body rotating plate 102. When the servo motor drives the cup body rotating plate 102 to rotate, the inner limiting wheel 104 and the outer limiting wheel 105 will be driven to rotate synchronously under the action of friction force, and the rotating cup body rotating plate 102 is pressed from the inside by the inner limiting wheel 104, thereby improving the rotation stability of the cup body rotating plate 102. The outer limiting wheel 105 abuts against the outer side of the cup body rotating plate 102 to prevent the cup body rotating plate 102 from moving outward along the axial direction when rotating.

[0038] The inner limiting wheel 107 is rotatably mounted on the top of the cup body conveying frame 101 through a bearing seat, and the outer limiting wheel 106 is integrally connected to the outer side of the inner limiting wheel 107 and is coaxially arranged with the inner limiting wheel 107. The outer peripheral surface of the outer limiting wheel 106 abuts against the outer side wall of the cup body rotating plate 102, and the inner limiting wheel 107 abuts against the inner side of the cup body rotating plate 102. When the servo motor drives the cup body rotating plate 102 to rotate, the outer limiting wheel 106 and the inner limiting wheel 107 will be driven to rotate synchronously under the action of friction, and the outer limiting wheel 106 presses the rotating cup body rotating plate 102 from the outside to improve the rotation stability of the cup body rotating plate 102. The inner limiting wheel 107 abuts against the inner side of the cup body rotating plate 102 to prevent the cup body rotating plate 102 from moving inward along the axial direction when rotating.

[0039] When the servo motor drives the cup body rotating plate 102 to rotate, the inner wheel 104 and the outer wheel 106 respectively abut against the inner circumference and the outer circumference of the cup body rotating plate 102 to improve the rotation stability of the cup body rotating plate 102. The outer limiting wheel 105 and the inner limiting wheel 107 respectively abut against the inner wall and the outer wall of the cup body rotating plate 102 to limit the axial position of the cup body rotating plate 102.

[0040] The conveying unit is fixed on the side of the first carrier plate 108 close to the second carrier plate 109, and is used to convey the cup body 5 to be turned over. The conveying unit includes a support frame 1010, a groove 1011 and a conveying roller 1012. The support frame 1010 has two pieces and is arranged oppositely on the top of the first carrier plate 108, such as Figure 5 As shown, the inner sides of the two support frames 1010 are perpendicular to each other, that is, the inner side angle of the two support frames 1010 is 90°. Grooves 1011 are arranged at intervals on the inner side of the support frames 1010, and conveying rollers 1012 are rotatably installed in the grooves 1011, and the cup body to be turned over is conveyed to the conveying rollers 1012.

[0041] Since the inner sides of the two support frames 1010 are perpendicular to each other, the conveying rollers 1012 on the support frames 1010 are also perpendicular to each other. The cup body is just tangent to the conveying rollers 1012 on both sides during transportation. During the conveying process, it can ensure that there is enough contact area between the cup body and the conveying rollers 1012, and at the same time, the centering positioning of the cup body is completed through the right-angle V shape, and then the adjustment wheel 1015 is used to complete the positioning and clamping of the cup body.

[0042] The baffle 1013 is fixed on the side of the second carrier 109 close to the first carrier 108, the adjustment rod 1016 passes through the baffle 1013 and the adjustment plate 1014 is fixed on the inner side of the adjustment rod 1016. The spring 1017 is sleeved on the adjustment rod 1016 and is located between the baffle 1013 and the adjustment plate 1014. By providing the spring 1017, it can meet the positioning work of cups with different diameters, and prevent the cup from tipping over or shifting under the action of inertia when turning the cup, which affects the normal clamping of the cup; at the same time, a buffering force is applied to the side of the cup when positioning and clamping the cup, so as to avoid leaving an indentation on the surface of the cup due to the clamping transition.

[0043] The adjusting wheel 1015 is rotatably mounted on the inner side of the adjusting plate 1014 and abuts against the outer side wall of the cup body to position and clamp the cup body transported thereto. The anti-slip plate 1018 is fixed to the end of the adjusting rod 1016 away from the adjusting wheel 1015, and the diameter of the anti-slip plate 1018 is larger than the diameter of the adjusting rod 1016. When the cup body clamping assembly 11 takes away the turned cup body, the adjusting rod 1016 will be driven to move toward the side close to the support frame 1010 under the reverse force of the spring 1017. The anti-slip plate 1018 can prevent the adjusting rod 1016 from slipping out of the baffle 1013.

[0044] like Figure 6 As shown, the cup conveying frame 101 is also provided with a conveying unit for conveying the cup to the conveying unit of the first carrier plate 108. The gantry 1019 is fixed on the top of the cup conveying frame 101, the lifting cylinder is fixed on the top of the gantry 1019, and the first lifting plate 1020 is connected to the lifting cylinder. The rotating cylinder is fixed on the bottom of the first lifting plate 1020, and the finger cylinder 1021 is connected to the rotating part of the rotating cylinder.

[0045] When the operator places the cup body on the conveying unit of the cup body conveying rack 101, the cup body may be placed in the wrong direction. Figure 6 As shown (i.e., the groove of the cup body is arranged to face left, so that the first carrier plate 108 and the second carrier plate 109 turn the groove upward when turning over; if the groove of the cup body is arranged to face right, the groove will face downward after turning over).

[0046] Therefore, the first lifting plate 1020, the rotating cylinder and the finger cylinder 1021 are provided to clamp the cup body which is placed in the reverse direction, rotate it horizontally by 180 degrees and then place it on the conveying unit.

[0047] The conveying process of the cup conveying assembly 10 is as follows:

[0048] First, the operator places the cup body on the conveying unit of the cup body conveying rack 101, adjusts the position of the upside-down cup body through the finger cylinder 1021, and then conveys the cup body to the conveying unit of the first carrier 108; since the inner sides of the two support racks 1010 are perpendicular to each other, the cup body conveyed thereto will be centered and positioned; then the cup body is clamped between the elastically set adjustment wheels 1015, and the rotating motor drives the cup body rotating plate 102 to rotate 90° clockwise, and the first carrier 108 and the second carrier 109 rotate 90° clockwise at the same time, turning the horizontally placed cup body to a vertical state. Under the joint action of the support rack 1010 and the adjustment wheel 1015, the cup body will not tip over or shift in position during the flipping process (the gap between the two support racks 1010 is to avoid the clamping of the cup body clamping assembly 11 to avoid interference).

[0049] The cup body gripping assembly 11 is used to grip the cup body after flipping and is placed on the top of the cup bottom. Figure 7 As shown, the cup body clamping assembly 11 includes a first driving frame and a clamping head. The clamping head is used to clamp the turned cup body, and the cup body is placed on the top of the cup bottom under the drive of the first driving frame.

[0050] The first driving frame includes a cup body clamping frame 110, a moving plate 111 and a second lifting plate 112. The cup body clamping frame 110 is fixed to the welding machine by screw fastening, and the moving plate 111 is slidably connected to one side of the cup body clamping frame 110 by means of a slide rail and a slider. A moving cylinder connected to the moving plate 111 is fixed to the side of the cup body clamping frame 110 to drive the moving plate 111 to move.

[0051] The second lifting plate 112 is installed on a side of the moving plate 111 away from the cup body clamping frame 110 through a lifting slide, and the second lifting plate 112 is driven to perform lifting motion through the lifting slide.

[0052] The gripping head is fixed on the second lifting plate 112 and is used to grip the cup body after flipping. Figure 8 , 9 As shown, the clamping head includes a clamping disc 113, a first shrinking block 114, a second shrinking block 115, a clamping groove 116, a clamping plate 117, a butt 118, a contact portion 119, an oblique pin 1110, a lifting block 1111 and an oblique groove 1112. The clamping disc 113 is fixed to the bottom of the second lifting plate 112, and the first shrinking block 114 is slidably connected to the inner side of the clamping disc 113 and is arranged in three groups in a ring. Through the three groups of first shrinking blocks 114 arranged in a ring, the cup body after the flip is centrally clamped, thereby improving the accuracy of the position of the cup body during clamping and transfer.

[0053] The lifting cylinder is fixed on the top of the second lifting plate 112, and the lifting block 1111 is connected to the lifting cylinder and arranged in the clamping plate 113, and the lifting cylinder drives the lifting block 1111 to do lifting motion. The inclined slot 1112 is obliquely opened in the lifting block 1111, and the inclined pin 1110 is integrally connected to the top of the first shrinking block 114 and inserted in the inclined slot 1112. The lifting cylinder drives the lifting block 1111 to do lifting motion, thereby driving the three groups of first shrinking blocks 114 to move inward or open outward synchronously, so as to realize the centering clamping of the cup body.

[0054] The second shrink block 115 is fixed to the bottom of the first shrink block 114 and moves synchronously with the first shrink block 114. The clamping groove 116 is opened on the inner side of the second shrink block 115, and the clamping plate 117 is arranged in the clamping groove 116 and connected to the clamping groove 116 through a pivot. Since the clamping plate 117 is connected to the second shrink block 115 through a pivot, the clamping plate 117 can swing freely in the clamping groove 116.

[0055] The abutment 118 is integrally connected to both sides of the clamping plate 117, and an arc-shaped contact portion 119 is provided on the inner side of the abutment 118. When the first shrink block 114 moves inward, it will drive the second shrink block 115 to move inward synchronously. Since the clamping plate 117 and the second shrink block 115 are pivotally connected, the clamping plate 117 will swing when it moves inward, and finally the clamping plate 117 completes the floating clamping of the cup body (even if there are some defects on the surface of the cup body: such as depressions or protrusions, the cup body can still be clamped).

[0056] Two abutment heads 118 are arranged on the inner side of each clamping plate 117 to increase the contact points with the cup body and improve the stability of clamping. The arrangement of the arc-shaped contact portion 119 can better match the outer surface of the cup body.

[0057] like Figure 1-3 , which is a schematic diagram of the structure of the welding assembly 12.

[0064] In one embodiment of the present application, the welding assembly 12 also includes a support vertical plate 1210 and a support plate 1212, one end of the support vertical plate 1210 is fixedly connected to the second connecting plate 129, and the support plate 1212 is fixedly installed on the other side of the support vertical plate 1210; the second drive motor 1211 is fixedly installed on the support plate 1212.

[0068] The welding principle of the utility model dual laser welding machine is as follows:

[0069] First, the operator places the cup bottom to be welded on the welding machine, and places the cup body on the cup body conveying assembly 10.
