Referring to fig. 1 and 4 together, a method for laser welding the transparent balloon provided by the present application will now be described. The application provides a laser welding method of a transparent balloon, which is used for welding an encapsulation film 10 at a notch 201 of a transparent balloon 20 to cover the notch. The transparent balloon 20 of the application comprises a balloon body 21 with a hollow structure inside and a catheter 22 communicated with the inside of the balloon body 21, and a notch 201 is formed in the welding side 211 of the balloon body. Here, the side of the balloon body 21 where the notch 201 is formed is defined as a "welding side 211", and the other side of the balloon body 21 opposite to the welding side 211 in the bonding direction is defined as a "non-welding side 212". The "pressing direction" refers to a direction in which the balloon body 21 is pressed by the pressing jig during welding, and is the "Z" axis direction shown in fig. 1. The "X-axis direction" shown in fig. 1 refers to the longitudinal direction of the balloon body, and the "Y-axis direction" shown in fig. 1 refers to the width direction of the balloon body.
Referring to fig. 1, the laser welding method for the transparent balloon provided by the present application includes steps S100, S200, and S300.
S100, pressing the packaging film at the notch of the balloon body by using a pressing jig to seal the notch, wherein the width of the light blocking sheet is smaller than that of the pressed catheter.
In step S100, the balloon body 21 may be circular, elliptical, or square, and the catheter may be circular, elliptical, or square. Because sacculus body 21 can take place deformation after the pressfitting, wholly be the platykurtic, sacculus body 21 has certain tensile in width direction, and then makes the width of pipe 22 after the pressfitting be greater than the width before the pressfitting. The width W1 of the light blocking sheet 30 is set to be smaller than the width W2 of the catheter 22 after being pressed, so as to ensure that the light blocking sheet 30 can smoothly extend into the balloon body 21 from the catheter 22 in the subsequent process. Specifically, the pressing jig can be made of glass.
Step S100 "pressing the encapsulation film at the notch of the balloon body with the pressing jig to cover the notch" may specifically include the steps of:
and S110, placing the packaging film on the welding side of the balloon body to seal the notch.

In step S200, since the balloon body 21 is deformed into a flat shape under the pressing of the pressing jig, the distance between the welding side 211 and the non-welding side 212 of the balloon body 21 is smaller, in order to avoid soldering the solder side 211 of the capsule body 21 to the encapsulation film 10, meanwhile, the non-welding side 212 of the balloon body 21 is also welded together, as shown in fig. 6 to 8, the light-blocking sheet 30 is placed inside the balloon body 21 through the catheter 22, and the light-blocking sheet 30 is opposite to the packaging film 10, the welding side 211 and the non-welding side 212 of the balloon body 21 can be isolated from each other, which can act as a laser shielding, when the laser passes through the welding side 211 of the balloon body 21 to reach the light blocking sheet 30, the laser energy is absorbed or reflected by the light blocking sheet 30, so that the non-welding side 212 of the balloon body 21 is prevented from being welded together due to the fact that the laser irradiates the non-welding side 212 of the balloon body 21.
Since the laser irradiation position is mainly located on the periphery of the packaging film 10, and the size of the light blocking sheet 30 is set to be larger than that of the packaging film 10, the light blocking sheet 30 can completely cover the position of the packaging film 10, and it can be ensured that no laser penetrates through the light blocking sheet 30 and irradiates the non-welding side 212 of the balloon body 21.
S300, utilizing laser to penetrate through the packaging film and focus on a contact welding surface between the packaging film and the balloon body, so as to weld the packaging film and the welding side of the balloon body into a whole.
In step S300, the laser penetrates through the packaging film 10 and focuses on the contact welding surface between the packaging film 10 and the balloon body 211, so that the packaging film 10 and the balloon body 21 begin to melt after absorbing the laser energy at the contact welding surface, and the packaging film 10 and the balloon body 21 are welded together, so that the packaging film 10 covers the notch 201 of the balloon body 21.
The application provides a laser welding method of a transparent balloon, which utilizes a pressing fixture to press a packaging film at a gap of a balloon body to seal the gap, wherein the width of a light-blocking sheet is smaller than that of a pressed catheter, then the light-blocking sheet is placed in the balloon body through the catheter and is opposite to the packaging film, the size of the light-blocking sheet is larger than that of the packaging film to completely cover the packaging film, finally laser penetrates through the packaging film and is focused on a contact welding surface between the packaging film and the balloon body to weld the packaging film and the welding side of the balloon body into a whole, due to the arrangement of the light-blocking sheet, the welding side and the non-welding side of the balloon body can be separated to play a role of blocking the laser, when the laser penetrates through the welding side of the balloon body to reach the light-blocking sheet, the laser energy is absorbed or reflected to avoid the laser irradiating the non-welding side of the balloon body to cause the non-welding side of the balloon body to be welded together, thereby effectively improving the yield of the product.

Because the notch 201 of the balloon body 21 is generally large, the size of the catheter 22 is small, and in order to achieve that the light blocking sheet 30 placed in the small-caliber catheter 22 can completely cover the packaging film 10, the width W1 of the single light blocking sheet 30 adopted in the present application is smaller than the width W2 of the catheter 22 after being pressed, and the length L1 of the single light blocking sheet 30 is greater than or equal to the length L3 of the packaging film 10, after the light blocking sheet 30 is placed in the balloon body 21 from the catheter 22, the light blocking sheets 30 are spliced together along the width direction of the balloon body 21, so that the whole width W4 of the spliced light blocking sheets 30 is greater than or equal to the width W3 of the packaging film 10, thereby achieving the light blocking effect, and being simple and convenient to operate.
It should be noted that the widths of the light blocking sheets 30 may be the same or different, and may be set according to actual needs, for example, in one embodiment, the widths of the light blocking sheets 30 may be the same, and in another embodiment, the widths of the light blocking sheets 30 may also be different. However, the width W1 of the single light blocking sheet 30 is ensured to be smaller than the width W2 of the pressed catheter 22, so that the light blocking sheet 30 can smoothly extend into the balloon body 21 from the catheter 22, and meanwhile, the total width W4 of the spliced light blocking sheet 30 is ensured to be larger than or equal to the width W3 of the packaging film 10, so that the laser can be completely shielded.
