The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0038] Example 1

[0039] like Figure 1-4 As shown, the present invention provides a technical solution: a high-frequency induction double-sided welding machine, comprising a welding machine body 1, a welding platform of the welding machine body 1 is provided with an installation opening 2, a welding mechanism 3 is installed in the installation opening 2, and a transverse servo module 4 is arranged on the front of the welding mechanism 3 and located on the welding machine body 1, and the transverse servo module 4 drives the upper welding carrier 5 to move horizontally left and right, and then moves into the welding mechanism 3;

[0040] It should be added that the transverse movement servo module 4 is composed of a linear motor 41 and a module slide 42 . The linear motor 41 drives the carrier platform 51 to move, and the carrier platform 51 is used for placing and clamping the welding carrier 5 .

[0041] The welding mechanism 3 includes a welding knife 31, a front pressure head 32 and a rear pressure head 33 that correspond to each other in the upper and lower parts. The welding knife 31, the front pressure head 32 and the rear pressure head 33 are all installed on the vertical movement servo module 6. The front pressure head 32 and the rear pressure head 33 are arranged front and back. The welding knife 31 is located between the front pressure head 32 and the rear pressure head 33. The upper and lower vertical movement servo modules 6 operate correspondingly to make the upper and lower front pressure heads 32, the rear pressure head 33 and the welding knife 31 dock and clamp the welding parts and welding areas of the product in turn. A coil 34 is arranged on the welding knife 31, and the coil 34 is sleeved on the U-shaped magnet 35. An external power supply supplies high-frequency current to the coil 34, so that a magnetic field is generated in the U-shaped magnet 35, and the magnetic field is transmitted to the welding area through the welding knife 31.

[0042] It should be noted that the welding head is composed of three parts, a welding knife 31, a front pressing head 32 and a rear pressing head 33. The two ends of the U-shaped magnet 35 fix the upper and lower welding knives 31 so that the upper and lower welding knives 31 correspond to each other.

[0043] There are also three corresponding welding knives 31, front pressure head 32 and rear pressure head 33 below;

[0044] In combination with the above embodiment, the worker puts the product into the welding carrier 5 and then into the platform. The carrier platform 51 positions the welding carrier 5 left and right, front and back. After positioning, it is moved to the bottom of the welding head through the transverse servo module 4. After moving to the welding area, the upper and lower front pressure heads 32 and the rear pressure head 33 respectively press the head and tail of the wire, and then the upper and lower welding knives 31 are connected at the same time for welding. The front and rear pressure heads 33 rise, and the lower one falls, and the welding head goes back. After welding, the carrier withdraws.

[0045] Among them, welding is a high-frequency magnetic field, a high-frequency changing magnetic field. This magnetic field generates eddy current heating inside the product, causing the solder to melt and achieve the welding effect.

[0046] Example 2

[0047] like Figure 1-3 As shown, the welding mechanism 3 is installed on the support frame 21 in the installation opening 2, and is used for the installation of the vertical movement servo module 6;

[0048] Furthermore, the vertical movement servo module 6 driving the welding knife 31 and the front pressure head 32 is installed in front of the support frame 21, while the vertical movement servo module 6 driving the rear pressure head 33 is installed behind the support frame 21;

[0049] Transverse guide rails 8 are installed horizontally in front of the support frame 21. Two sets of linear sliders 81 are slidably connected to each set of transverse guide rails 8, which are used to install the welding knife 31 and the front pressure head 32 respectively, and are used to drive the lateral movement of the welding knife 31 and the front pressure head 32.

[0050] like Figure 1 As shown, a cover body 11 is installed on the top of the welding platform of the welding machine body 1 and is located outside the welding mechanism 3. The cover body 11 is built into the welding mechanism 3 to protect the operator from flying sparks or high temperature damage. The cover body 11 is provided with a control port on the 4 sides corresponding to the transverse servo module to facilitate the operator to make necessary adjustments and operations. The end face is also equipped with control buttons and a display panel, and the welding machine body 1 is controlled by the control buttons and the display panel.

[0051] like Figure 2 As shown, the vertical movement servo module 6 is composed of a servo motor 61 and a screw linear motion mechanism 62. The screw linear motion mechanism 62 is driven by the servo motor 61 to drive the screw linear motion mechanism 62 to vertically adjust the welding knife 31, the front pressure head 32 and the rear pressure head 33.

[0052] Among them, the screw linear motion mechanism 62 is a transmission device that converts rotational motion into linear motion, and is mainly composed of a screw, a nut, a guide rail, a slider, a motor and other components; it rotates the screw (driven by the servo motor 61) to make the nut move along the axial direction of the screw, thereby driving the components connected to it to perform linear motion. In the welding mechanism 3, the screw linear motion mechanism 62 is mainly used to drive the welding knife 31, the front pressure head 32 and the rear pressure head 33 to move up and down to achieve precise welding operations.

[0053] like Figure 2 As shown, the welding knife 31, the front pressure head 32 and the rear pressure head 33 are equipped with pressure sensors 7, and the pressure sensor 7 is electrically connected to the control main board, and has the function of monitoring and adjusting the pressure of the welding knife 31, the front pressure head 32 and the rear pressure head 33. The sensor is electrically connected to the control system, monitors the pressure of each component in real time, and feeds back the data to the control main board. Through these data, the control main board can automatically adjust the pressure of each component to prevent welding quality problems or equipment damage caused by excessive or insufficient pressure.

[0054] The working process of the present invention is as follows: workers first place the product on the welding carrier 5 according to the requirements, and realize the left and right front and back positioning of the product by the clamping connection of the welding carrier 5 and the carrier platform 51. After positioning, the welding carrier 5 is moved left and right on the welding platform by the transverse servo module 4 (composed of a linear motor 41 and a module slide 42). The transverse servo module 4 can accurately move the welding carrier 5 to the welding area directly below the welding mechanism 3. When the welding carrier 5 moves to the welding area, the front pressure head 32, the rear pressure head 33 and the upper and lower welding knives 31 are adjusted up and down under the action of the vertical servo module 6. The U-shaped magnet is connected to the welding part and contacts and clamps it. After the welding knife 31 and the front pressure head 32 and the rear pressure head 33 clamp the product, the power supply supplies power to the coil 34 on the U-shaped magnet to generate a high-frequency current, so that a magnetic field is generated in the U-shaped magnet. The magnetic field is transmitted to the welded area through the welding knife 31. The high-frequency changing magnetic field heats the metal in the welded area and melts the tin in the welded area to achieve the purpose of welding. After welding is completed, the upper and lower welding knives 31 are opened at the same time, the upper and lower front and rear pressure heads 33 are opened, the lateral movement servo module 4 moves out of the welding area, and the workpiece is taken out to complete the welding operation.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
