Description

Technical Field

[0001] This utility model belongs to the field of welding equipment technology, and more specifically, it relates to a high-efficiency automatic welding device for the inner liner of a thermos cup. Background Technology

[0002] When manufacturing a thermos, the inner liner and the body need to be made separately. The inner liner requires the body and bottom to be made separately. Then, an automatic welding device is used to efficiently weld the body and bottom together to form the inner liner, ensuring the heat preservation quality of the inner liner.

[0003] According to CN201910092678.X, this invention discloses a welding device for the inner liner of a thermos cup, including a welding machine, a monitoring unit, a chuck, an active turntable, a first motor, a control device, a base plate, and a second motor. A support is provided on the base plate, and the second motor drives the support to move back and forth on a slide rail on the base plate. The first motor is fixed to the support, and the active turntable is fixed to the output shaft of the first motor. The chuck is fixed to the other side of the active turntable. The welding machine is located on the base plate and has a passive turntable on the side near the support. A nozzle fixture is provided on the other side of the passive turntable. The welding torch of the welding machine passes through the passive turntable and the nozzle fixture. The monitoring unit includes a monitoring probe fixed to the welding torch and a probe screen fixed to the side of the welding machine. The device allows for visual welding by inserting the fixed welding torch into the rotating inner liner of the thermos cup, enabling welding of the inner liner from the inside. The operation is simple and ensures the smoothness of the weld seam inside the inner liner of the thermos cup.

[0004] Based on the above, existing automatic welding equipment generally uses a clamping device to hold the cup body and cup bottom, and then uses a welding head structure to perform welding. In order to ensure that the welding head is positioned at the cup body and cup bottom during welding, the welding head is close to the cup body and cup bottom. When the staff picks up and puts the cup body and cup bottom, they are prone to bumping the welding head, which can easily lead to damage to the welding head and affect the welding quality of the welding equipment. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a highly efficient automatic welding device for the inner liner of a thermos cup. This solves the problem that existing automatic welding devices typically use a clamping device to hold the cup body and bottom, and then use a welding head structure for welding. To ensure the welding head is positioned close to the cup body and bottom during welding, workers are prone to bumping or damaging the welding head when handling the cup body and bottom, thus affecting the welding quality of the welding device.

[0006] The purpose and effectiveness of this utility model, a highly efficient automatic welding device for the inner liner of a thermos cup, are achieved through the following specific technical means:

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention employs a welding moving mechanism to ensure that when the inner cup body and cup bottom are placed on the cup bottom placement block and cup body placement rack, the moving welding head is positioned away from these blocks. This facilitates the placement of the cup body and cup bottom inside the blocks and rack. When the cup body and cup bottom are clamped together, the moving welding head moves to the welding position to perform welding. This avoids damage to the moving welding head caused by workers bumping into it when handling the inner cup, reducing the probability of damage and ensuring the service life of the moving welding head.
