Description

Technical Field

[0001] The present technical solution relates to the technical field of energy storage cups, and in particular to an energy storage cup bottom plate welding machine. Background Art

[0002] An energy storage cup consists of a body, lid, and heated base. The body incorporates a layer of phase-change energy storage material, while the heated base heats the outer wall. This heat is then transferred to the phase-change material and then to the cold water in the cup through the inner wall, allowing for long-term warmth during travel. Existing energy storage cup film production requires manual welding of the film to the bottom of the cup, resulting in low production efficiency and high costs. Furthermore, manual welding makes it difficult to ensure consistent weld quality, leading to a high rate of product rejection and requiring improvement. Summary of the Invention

[0003] In order to improve the problem of low production efficiency caused by manual welding of energy storage cup bottom plates, this technical solution provides an energy storage cup bottom plate welding machine.

[0004] The purpose of this technical solution is achieved in this way:

[0005] An energy storage cup bottom plate welding machine comprises a frame, wherein a workbench is provided on the frame;

[0006] A material transfer device, which is provided on the workbench and is used to move the energy storage cup to load the material;

[0007] A welding device, which is arranged on the frame and located above the material transfer device, and is used to perform welding operations on the energy storage cup bottom plate on the material transfer device;

[0008] Among them, the material transfer device includes a loading platform and a material transfer driving component. The loading platform is rotatably set on the workbench. A mold base for positioning the energy storage cup is set on the loading platform. The material transfer driving component drives the loading platform to rotate circumferentially around the axis so that the position of the mold base is aligned with the welding device.

[0009] Through the above technical solution, when an energy storage cup bottom film welding machine is in normal use, the material transfer drive component drives the loading platform to rotate around the axis to drive the mold base to change its position, so that the mold base can flexibly switch between the loading station and the welding station. When in the loading station, the energy storage cup is placed upside down on the mold base with its bottom end facing upward, and the energy storage cup bottom film is placed in the welding position of the cup bottom. When in the welding station, the energy storage cup position is aligned with the welding device, and the welding device is driven toward the loading platform, so that the welding end can accurately weld the energy storage cup bottom film on the mold base to the bottom of the energy storage cup, thereby improving production efficiency.

[0010] Preferably, there are multiple mold bases, and the multiple mold bases are distributed circumferentially around the rotation axis of the loading platform.

[0011] Through the above technical solution, each mold base carries a corresponding energy storage cup, and multiple mold bases are evenly spaced on the loading platform. The material transfer drive accurately controls the rotation angle through the cam divider, so that each time one mold base can be in the welding position and the other mold base can be in the loading position. The energy storage cup loading and welding operations can be carried out at the same time. By increasing the number of mold bases, the production cycle is shortened and the production efficiency is further improved.

[0012] Preferably, the upper end surface of the mold base has a dosing groove, and the dosing groove is adapted to the cup mouth end of the energy storage cup, so that the cup mouth of the energy storage cup is engaged in the dosing groove with the cup mouth facing downward.

[0013] Through the above technical solution, the material fixing groove of the mold base is adapted to the cup mouth of the energy storage cup, so that the energy storage cup is fixed on the mold base by snapping into the material fixing groove, limiting the movement or tilting of the energy storage cup during the movement and welding process, thereby improving stability and accuracy.

[0014] Preferably, the welding device includes a welding drive and a welding head arranged on the welding drive. The frame is also provided with a sliding drive, which is used to drive the welding head to move toward the workbench so that the welding drive drives the welding head to weld the workpiece on the mold base.

[0015] Through the above technical solution, the welding device consists of a welding drive and a welding head. The sliding drive drives the welding head to move toward the loading platform. The welding drive drives the welding head to operate to weld the energy storage cup base on the mold base. The sliding drive performs precise movement and adjustment according to the welding requirements to ensure that the welding head always remains in the best working position, thereby improving the quality and efficiency of welding.

[0016] Preferably, the workbench is provided with a guide shaft, a sliding sleeve on the guide shaft is provided with a sliding seat, and the sliding direction of the sliding seat is parallel to the rotation axis of the loading platform;

[0017] The sliding seat is provided with the welding device, and the sliding driving member drives the welding device to move up and down by driving the sliding seat to slide.

[0018] Through the above technical solution, the guide shaft is passed through the sliding seat, so that the guide seat moves along the axial direction of the guide shaft. Based on the welding device being fixed on the guide seat, the up and down lifting directions of the welding device are restricted to remain consistent and stable, thereby further improving the welding accuracy and stability.

[0019] Preferably, the lower portion of the sliding seat is provided with abutting connection portions and side extension portions, the side extension portions are connected to opposite sides of the abutting connection portions, and the side extension portions cooperate with the abutting connection portions to enclose a clearance space;

[0020] The welding device is located in the clearance space, and the abutting connection portion is provided with a through hole for the welding head to pass through.

[0021] Through the above technical solution, the side extension parts are located on both sides of the connecting extension part, and they work closely with the connecting extension part to form a solid frame with a clearance space. When the sliding drive part drives the welding head close to the workpiece, the abutting connection part first abuts against the bottom of the energy storage cup, and the welding drive part drives the welding head through the through hole to perform welding work, avoiding direct contact when the welding head descends, and the impact and wear it receives are appropriately reduced, thereby improving the protection effect of the welding head and extending its service life.

[0022] Preferably, the mold base includes a base portion fixed to the loading platform and a material fixing portion provided on the base portion, the material fixing portion is provided with the material fixing groove, and the material fixing portion is detachably connected to the base portion.

[0023] Through the above technical solution, each dosing part with a dosing groove is used to engage the energy storage cup. By disassembling the structure and replacing the dosing part, it can adapt to energy storage cups of different types and sizes, thereby increasing versatility.

[0024] Compared with the existing technology, this technical solution has the following outstanding and beneficial technical effects:

[0025] 1. This technical solution adopts a method in which the material transfer drive member drives the loading platform to rotate axially to drive the mold base to switch between the loading station and the welding station. When in the loading station, the energy storage cup and the bottom of the energy storage cup are prepared on the mold base. When in the welding station, the energy storage cup is aligned with the welding device, and the welding device is close to the loading platform to accurately weld the energy storage cup bottom plate to the bottom of the energy storage cup. The cycle operation improves production efficiency.

[0026] 2. This technical solution distributes multiple die holders axially around the loading platform, and multiple die holders work together to shorten the processing cycle and further improve production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
