Description

Technical Field

[0001] This utility model relates to the field of welding technology, specifically to an automatic edge-wrapping mechanism. Background Technology

[0002] Ultrasonic edge welding is a highly efficient material joining process that uses high-frequency mechanical vibration to cause thermoplastic material molecules to generate heat through friction, instantly melt, and then be pressed and shaped to achieve seamless covering or decorative stitching. For example, in the production of some automotive interior parts, fabric is wrapped around the edges of the interior parts to improve their aesthetics.

[0003] Traditional edge-wrapping equipment typically uses a vertically moving welding head, which can be obstructed and restricted when wrapping products with complex edges. It also has poor adaptability and cannot be adjusted according to actual edge-wrapping needs. Therefore, this utility model proposes an automatic edge-wrapping mechanism that can solve the above problems. Utility Model Content

[0007] The support assembly includes a base located at the top of the second carrier, a column rod movably passing through the base rod, the column rod passing through the second carrier and screwed with a bushing, and a support platform connected to the front end of the base rod;

[0008] A cylinder is installed on the upper end of the support plate. The cylinder is used to drive the support plate to rotate the ultrasonic welding machine for welding. A limiting part is provided on the first frame. The limiting part is used to adjust the rotation angle of the ultrasonic welding machine.

[0009] Preferably, the ultrasonic welding machine includes an ultrasonic transducer, the ultrasonic transducer is connected to an amplitude transformer, and the amplitude transformer is connected to a welding head.

[0010] Preferably, the jacket includes a pad and a pressure block, the pad being fixed to the upper end of the support plate, and the pressure block being connected to the pad by bolts and locked onto the node of the amplitude transformer.

[0011] Preferably, the limiting part includes a horizontal plate fixed to the first carrier, the horizontal plate being screwed with a first limiting rod and a second limiting rod, and the first limiting rod and the second limiting rod being screwed with limiting sleeves respectively.

[0012] Preferably, the upper end of the seat has a protrusion and a pad, the pad is connected to two sets of support blocks, and the protrusion is located between the two sets of support blocks.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] Relative vertical welding has the advantages of high speed and efficiency, makes it easier to observe the welding position during welding, effectively improves welding quality, and the welding head is less likely to be obstructed or restricted;

[0020] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3

[0022] Provide an automatic edge-binding mechanism:

[0023] The support plate 10 has a first support frame 11 and a second support frame 12. The first support frame 11 and the second support frame 12 are fixedly connected to the support plate 10. The support plate 10 is installed on the machine tool or workbench, which plays a role in stabilizing and supporting the support plate 10.

[0024] The welding assembly includes a movable block 33 rotatably connected to the first carrier 11, the upper end of the movable block 33 having a support plate 30, and the support plate 30 being connected to an ultrasonic welding machine 32 via a jacket 31;

[0025] The ultrasonic welding machine 32 includes an ultrasonic transducer 321, which is connected to an amplitude transformer 322. The amplitude transformer 322 is connected to a welding head 323. The ultrasonic transducer 321 converts the high-frequency electrical energy generated by the ultrasonic generator into mechanical vibration of the same frequency. The vibration is amplified by the amplitude transformer 322, and the amplified vibration energy is transmitted to the welding head 323.

[0026] The jacket 31 includes a pad 311 and a pressure block 312. The pad 311 is fixed to the upper end of the support plate 30. The pressure block 312 is connected to the pad 311 by bolts and locked to the node of the amplitude transformer 322. By locking the pad 311 and the pressure block 312 to the node of the amplitude transformer 322, vibration can be isolated to the maximum extent, ensuring the efficient and stable operation of the ultrasonic welding machine 32.

[0027] The support assembly includes a base 40 located on top of the second carrier 12, and a support platform 44 connected to the front end of the base 40. The support platform 44 is used to support the welded product.

[0028] The seat 40 is movably connected to the column rod 45, which passes through the second carrier 12 and is screwed to the abutment sleeve. The abutment sleeve abuts against the seat 40, locking the position of the seat 40 in the second carrier 12. When adjustment is required, the seat 40 is loosened by rotating the abutment sleeve, so that the seat 40 can drive the support platform 44 to rotate for position adjustment.

[0029] A cylinder 50 is installed on the upper end of the support plate 10. The cylinder 50 is used to drive the support plate 30 to rotate the ultrasonic welding machine 32 for welding. The cylinder 50 is preferably a pneumatic cylinder. The cylinder 50 can use a foot switch as the input signal and be controlled by a PLC.

[0030] During welding, the product with the fabric wrapped around its edges is placed on the support platform 44. The control cylinder drives the ultrasonic welding machine 32 to pivot and then weld, realizing welding while moving. Through multi-point welding, the fabric is wrapped around the product. Compared with vertical welding, it has the advantages of high speed and high efficiency. It is easy to observe the welding position during welding, effectively improving the welding quality. The welding head 323 is not easily obstructed or restricted.

[0031] The first carrier 11 is provided with a limiting part 20, which is used to adjust the pivot angle of the ultrasonic welding machine 32;

[0032] The limiting part 20 includes a horizontal plate 21 fixed to the first carrier 11. The horizontal plate 21 is screwed with a first limiting rod 22 and a second limiting rod 23. The first limiting rod 22 and the second limiting rod 23 are respectively screwed with limiting sleeves 24. The first limiting rod 22 and the second limiting rod 23 are distributed on different sides of the first carrier 11 on the horizontal plate 21, and the first limiting rod 22 and the second limiting rod 23 have different extension heights. By adjusting the difference in extension height between the first limiting rod 22 and the second limiting rod 23, the pivot angle of the ultrasonic welding machine 32 can be limited. It can cooperate with the adjustable support table 44 to adapt to the edge welding needs of different products, and has good adaptability.

[0033] The upper end of the seat 40 has a protrusion 41 and a pad 42. The pad 42 is connected to two sets of support blocks 43. The protrusion 41 is located between the two sets of support blocks 43. During welding, the protrusion 41 and the two sets of support blocks 43 are on the underside of the product, pressing the fabric tightly.

[0034] 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.
