They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0018] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0019] The following is combined with Figure 1-3 The utility model is further described.

[0020] In order to solve the problems existing in the background technology, the present application proposes the following technical solution: a PHC luggage trunk cover strap spin welding device.

[0021] The specific technical solution includes an equipment frame 1 and a quick positioning component 4. The equipment is equipped with a two-hand start button and a double emergency stop button. The equipment table 2 is fixed inside the equipment frame 1. The equipment frame 1 and the equipment table 2 are used to support the entire welding device. A safety grating 6 is provided on one side of the equipment frame 1. The safety grating 6 is a safety protection device used in the field of industrial automation. It is mainly used to prevent workers from contacting machine parts or dangerous areas that endanger their life safety. It forms an invisible protection area by emitting and receiving light beams. When a person or object passes through this area, the safety grating 6 will immediately send a signal to stop the operation of the mechanical equipment. The reaction time is usually between 10 milliseconds and 30 milliseconds, which can quickly protect the operator. Safety, the safety grating 6 is composed of a group of transmitters and receivers to form a beam grid, which usually contains multiple beams (for example, 8, 14 or 30) that can cover different heights and widths. A rotating PLC control display 7 is provided on one side of the equipment frame 1, which integrates multi-parameter intelligent adjustment control systems such as temperature, pressure, and speed. It automatically adjusts welding parameters according to the characteristics of the welding material to ensure the stability and consistency of welding quality. Multiple foot pads 8 and two forklift plates 9 are fixed under the equipment frame 1. The forklift plate 9 facilitates the insertion of the forklift's fork arm to lift and carry the welding device. A cover support part 10 is provided on the inner side of the equipment frame 1. The equipment frame 1 contains a power distribution cabinet (including warning lights, touch screen, emergency stop switch, etc.).

[0022] A welding assembly 3 is provided on the inner side of the equipment frame 1. The welding assembly 3 includes a gantry frame 31 fixed above the equipment table 2. A bidirectional servo motor 32 is provided above the gantry frame 31. The bidirectional servo motor 32 can accurately control the moving position of the welding device or the spin welding joint 33 in two directions to ensure that it can move according to a predetermined trajectory during the welding process, thereby improving the accuracy of welding. A spin welding joint 33 is installed below the gantry frame 31. A special spin welding joint 33 is used to generate heat through rotational friction to achieve rapid welding of the drawstring and the trunk cover. The surface of the welding joint is specially treated to ensure the stability and wear resistance of the welding process. A cooling air pipe 34 is provided on the front of the gantry frame 31. The cooling air pipe 34 is designed next to the welding head to rapidly cool the spin-melted parts to improve production efficiency.

[0023] The quick positioning component 4 is arranged above the equipment table 2. The quick positioning component 4 is used to ensure the precise alignment of the welding component 3 with the drawstring and the trunk cover, reduce manual adjustment time, and improve welding efficiency. The quick positioning component 4 includes multiple support bases 41 fixed above the equipment table 2, multiple flip cylinders 42 fixed above the equipment table 2, a tensioning cylinder 43 fixed above the equipment table 2, and a crimping handle 44. The tensioning cylinder 43 usually uses air pressure to automatically apply and release pressure to ensure that the welded parts (i.e., the cover 5) maintain close contact during welding. By applying pressure evenly, the tensioning cylinder 43 can reduce welding defects such as pores, cracks, and uneven welds, thereby improving the strength and Quality, while being able to provide consistent pressure output, ensuring that the pressure conditions are the same during each welding process, reducing human operating errors, and achieving rapid clamping and loosening of workpieces, which helps to improve production efficiency and work rhythm. The crimping handle 44 is used to apply pressure manually or mechanically to ensure that the weldments can be tightly joined during welding, and the handle can help the operator maintain the position of the weldments during the welding process to prevent displacement or deformation during the welding process. The operator can quickly and conveniently control the welding process through the crimping handle 44, thereby improving work efficiency. A positioning bar 45 is installed at one end of the multiple flip cylinders 42. The flip cylinder 42 ensures the positioning and fit of the supply, and a cover plate 5 is provided above the support base 41.

[0024] To enable those skilled in the art to fully understand the technical solution, this application provides the following overall overview:

[0025] When in use, place the PHC cover 5 flat on the support base 41, fully position it, lay the drawstring flat to the installation position, fix the plastic pin to the spin welding joint 33, start the equipment, the spin welding joint 33 drives the plastic pin to rotate at high speed, and slowly presses it down to the PHC cover 5 drawstring fixing point. The plastic pin friction melts, the motor locks instantly, the cooling air pipe 34 blows up, and presses for 15 seconds to complete the drawstring spin welding fixation. It is equipped with a complete safety grating 6 as a safety protection device, such as a protective cover, an emergency stop button, etc., to ensure the personal safety of the operator. Through automatic control and rapid positioning of the component 4, an efficient and stable spin welding process is achieved, which improves the performance and production efficiency of the trunk cover. The device has the advantages of simple structure, easy operation, high welding quality, etc., and has broad application prospects and promotion value.
