Description

Technical Field

[0001] This utility model relates to the field of heat sealing welding machines, specifically an upper and lower heat sealing welding machine. Background Technology

[0002] A heat sealing welding machine is a device that uses heat and pressure to seal or join plastics, composite materials or other thermoplastic materials. It is widely used in packaging, medical, electronics, automotive and other industries.

[0003] In existing technologies, such as the welding equipment disclosed in Chinese patent CN221849093U, the welding head is usually fixed on a gantry, which can only move up and down or back and forth in one direction. When welding workpieces with complex contours or planes of different heights, operators need to frequently adjust the position and angle of the workpiece manually. This is not only cumbersome and inefficient, but also makes it difficult to ensure the accuracy of the welding position and the consistency of the weld quality. In particular, for scenarios that require simultaneous welding at multiple angles, existing equipment cannot meet the requirements, thus limiting its application scope.

[0004] Therefore, how to achieve flexible and precise multi-dimensional orientation adjustment of the welding pen has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0005] The purpose of this invention is to provide an upper and lower heat sealing welding machine, which aims to solve the problems mentioned in the background art, such as inconvenient adjustment of the welding pen position, inability to adapt to welding of complex workpieces, and low efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: by installing a base plate, a support column, a welding head assembly, and multiple adjustment mechanisms for adjusting the position and posture of the welding head assembly, the position and posture of the welding pen can be adjusted.

[0007] A top and bottom heat sealing welding machine includes a mounting base plate and a support column disposed on the mounting base plate. The machine is characterized by further including a welding head assembly and multiple adjustment mechanisms for adjusting the position and orientation of the welding head assembly, the multiple adjustment mechanisms including:

[0008] A horizontal adjustment mechanism, mounted on the support column, is used to drive the welding head assembly to move horizontally.

[0009] A vertical adjustment mechanism, connected to the horizontal adjustment mechanism, is used to drive the welding head assembly to move in the vertical direction;

[0010] An attitude adjustment mechanism, mounted on the vertical adjustment mechanism, is used to adjust the rotation angle of the welding pen.

[0011] As an improvement of this utility model: the horizontal adjustment mechanism includes a first connecting frame connected to the support column, a first moving drive component for driving, and a slider driven by the first moving drive component and connected to the fixed frame.

[0012] As an improvement of this utility model: the vertical adjustment mechanism includes a second connecting frame connected to the fixed frame, a movable rod slidably connected to the second connecting frame, and a second moving drive assembly for driving the movable rod to move up and down.

[0013] As an improvement of this utility model: the posture adjustment mechanism includes a mounting frame connected to the moving rod, a rotating shaft driven by a rotary motor in the mounting frame, and the welding pen is connected to the rotating shaft through a connecting sleeve, a fixing rod and a fixing sleeve.

[0014] As an improvement of this utility model: the first moving drive assembly includes a first motor fixed to the first connecting frame and a one-way screw driven therefrom, and the slider is threadedly connected to the one-way screw.

[0015] As an improvement of this utility model: the second moving drive assembly includes a second motor fixed to the second connecting frame and a bidirectional screw driven therefrom, the bidirectional screw being threadedly connected to a moving frame connected to the outer end of the moving rod.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention achieves composite adjustment of the welding pen's position and angle in three-dimensional space through three independent yet coordinated adjustment mechanisms: horizontal, vertical, and posture. It can easily handle workpieces with various complex shapes and different height planes, greatly expanding the application range of the equipment.

[0018] Each adjustment mechanism employs a precision transmission system using a motor and screw, enabling precise control of the welding pen's position and angle. Testing has shown that, compared to traditional manual or single-axis adjustment equipment, this solution can control welding positioning accuracy within 0.1mm, increasing the first-pass yield by over 15%, effectively ensuring the stability and consistency of welding quality.

[0019] By using electronic control, the welding pen can be automatically adjusted in all directions, replacing tedious manual adjustments and significantly simplifying the operation process. Calculations show that the time required to set and adjust the welding path for a complex workpiece can be reduced by more than 40% compared to traditional methods, greatly improving production efficiency.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0025] See Figures 1 to 3 In this embodiment of the utility model, an upper and lower heat sealing welding machine includes a mounting base plate 1, a support column 7, and a welding head adjustment system mounted thereon.

[0026] To facilitate equipment movement and stability, rolling components are provided at the four bottom corners of the mounting base plate 1. Specifically, the rolling components include the support legs 2 fixedly connected to the bottom of the mounting base plate 1, a rotating frame 3 rotatably connected to the bottom of the support legs 2, rollers 4 mounted on the rotating frame 3, and brakes 5 provided at the outer ends of the rollers 4 to lock the rollers 4 after the equipment is in place, ensuring stability during the welding process. To balance the center of gravity of the entire equipment, especially when the welding head extends far, a counterweight 6 is also provided at the top center of the mounting base plate 1.

[0027] The core of this utility model lies in its multi-dimensional adjustment system, which includes a horizontal adjustment mechanism, a vertical adjustment mechanism, and an attitude adjustment mechanism.

[0028] Horizontal adjustment mechanism: such as Figure 1As shown, a first connecting frame 8 is fixed to the top of the support column 7. A first moving drive assembly is installed on the first connecting frame 8, specifically a first motor 10 fixed thereon and a one-way screw 11 driven by it. The one-way screw 11 is threadedly connected to the slider 9. The slider 9 is connected to the fixed frame 13 through the connecting rod 12. When the first motor 10 works, it drives the one-way screw 11 to rotate, thereby causing the slider 9 to move in the horizontal direction. Then, through the connecting rod 12 and the fixed frame 13, it drives all the components connected thereafter to achieve overall horizontal front-back position adjustment.

[0029] Vertical adjustment mechanism: such as Figure 1 and Figure 3 As shown, a second connecting frame 14 is fixed to the front end of the fixed frame 13. A second moving drive assembly is installed on the outer wall of the second connecting frame 14, specifically a second motor 26 fixed by a connecting block 25 and a bidirectional screw 27 driven by it. Sliding sleeves 15 are embedded at the upper and lower ends of the second connecting frame 14. The moving rod 16 slides through the sliding sleeve 15. The outer end of the moving rod 16 is threadedly connected to the bidirectional screw 27 through the moving frame 24. When the second motor 26 works, it drives the bidirectional screw 27 to rotate. Through the threaded engagement, it drives the moving frame 24 to move up and down in the vertical direction, thereby driving the moving rod 16 to achieve synchronous vertical lifting and lowering movement.

[0030] Attitude adjustment mechanism: such as Figure 2 As shown, the inner end of the moving rod 16 is connected to a mounting frame 17, and a rotary motor 19 is installed inside the mounting frame 17. The output shaft of the rotary motor 19 is the rotating shaft 18, which is connected to the connecting sleeve 20. The inner end of the connecting sleeve 20 is connected to the fixed sleeve 22 via a fixing rod 21. Finally, a welding pen 23 is installed at the inner end of the fixed sleeve 22. The fixed sleeve 22 may have threaded holes or slots to facilitate the installation and replacement of the welding pen 23. When the rotary motor 19 is working, it drives the rotating shaft 18 to rotate, which in turn drives the welding pen 23 to rotate around the axis through a series of connecting parts, thereby adjusting its welding posture and angle.

[0031] The working principle of this utility model is as follows: the operator can start the first motor 10, the second motor 26 and the rotary motor 19 respectively through the control system. Starting the first motor 10 can adjust the horizontal front and rear position of the entire welding head assembly; starting the second motor 26 can adjust the vertical height of the welding pen 23; starting the rotary motor 19 can adjust the welding angle of the welding pen 23. The coordinated work of the three mechanisms realizes the precise and convenient adjustment of the orientation and posture of the welding pen, thereby facilitating the synchronous welding of the equipment or the welding of complex paths.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
