Description

Technical Field

[0001] This utility model belongs to the field of welding equipment, and specifically relates to a multi-axis synchronous patch welding machine. Background Technology

[0002] Surface mount soldering (SMT) machines are used in the electronics manufacturing industry. Currently, there is room for improvement in the precision of the soldering head movement during operation. This can easily lead to soldering position deviations, resulting in soldering defects such as cold solder joints, short circuits, and bridging. The root cause is the difficulty in achieving smooth and highly consistent operation in the multi-dimensional coordination of the equipment's movements; the movements in each direction are not tightly synchronized. The conventional approach is to meticulously adjust parameters such as soldering temperature, time, and pressure before soldering, while simultaneously optimizing the soldering process path. However, this approach has significant drawbacks. Parameter tuning is time-consuming, requires highly skilled technicians, and struggles to meet complex and ever-changing soldering needs. Soldering process optimization also has limitations; it is difficult to achieve broad applicability to DC power modules of different sizes and layouts. Therefore, a new structure is needed to address these technical problems. Utility Model Content

[0019] 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.

[0020] Please see Figures 1 to 3As the first embodiment of this utility model: a multi-axis synchronous patch welding machine includes: a working component 100 and a welding component 200. The welding component 200 for welding DC power modules is installed at the rear of the working component 100. The working component 100 includes a base plate 110 for mounting the workpiece. The upper surface of the base plate 110 is mounted with a workpiece for supporting the DC power module. The welding component 200 includes a base 210 for mounting the support arm. The support arm is rotatably mounted on the upper surface of the base 210. A welding head 260 is installed at the end of the support arm away from the base 210.

[0021] The working parts include mounting block 120, upright plate 130, mounting frame 140, connecting frame 150 and roller rod 160. A mounting block 120 is installed on the left edge and right edge of the upper surface of the base plate 110. The two mounting blocks 120 have the same structure. An upright plate 130 is installed on the upper surface of the two mounting blocks 120 respectively.

[0022] An installation frame 140 is installed on the upper edge between the two upright plates 130. Multiple grooves are evenly provided on the upper surface of the installation frame 140. Multiple roller rods 160 are rotatably installed on the upper surface of the installation frame 140 through the grooves.

[0023] The roller rod 160 has a cuboid connecting frame 150 installed at both ends, and the inner surface of the connecting frame 150 is rotatably connected to both ends of the roller rod 160.

[0024] In use, the user first places the DC power module to be welded on the upper surface of multiple roller rods 160, so that the DC power module is placed on the upper surface of the roller rods 160 inside the connecting frame 150. At this time, the user moves the DC power module, which will cause the roller rods 160 on its lower surface to rotate, thereby facilitating the user to move the DC power module on the upper surface of the workpiece, so as to weld the DC power module with the welding assembly 200. Since the DC power module is placed on the workpiece during use, it is convenient for the operator to perform loading and unloading operations, reducing labor intensity. At the same time, it is also beneficial to adjust and move the module synchronously during the welding process, improving the convenience and controllability of the work.

[0025] Please see Figures 1 to 3As a second embodiment of this utility model: based on the description in the above embodiments, a base 210 is further installed behind the base plate 110. The lower surface of the base 210 is flush with the lower surface of the base plate 110. The support arm includes a rotating seat 220, a first support arm body 230, a hinge seat 240, a second support arm body 250, and a hinged weld joint 260. The rotating seat 220 is rotatably installed on the upper surface of the base 210 by a stepper motor. The end of the rotating seat 220 away from the base 210 is hinged to the first support arm body 230 by a motor.

[0026] One end of the support arm body 230 away from the rotating seat 220 is hinged to the hinge seat 240 by a motor rotation. The other end of the hinge seat 240 away from the support arm body 230 is hinged to the support arm body 250 by a motor rotation. The other end of the support arm body 250 away from the hinge seat 240 is mounted with a welding head 260 by a motor rotation.

[0027] The welding head 260 is positioned above the working assembly 100 via a support arm and a base 210. The welding head 260 is a patch welding head 260, and the welding head 260 is electrically connected to an external device via a wire.

[0028] In use, when the DC power module is placed on the upper surface of the working component 100 for welding according to the operation steps of the first embodiment, the user can connect the welding component 200 to the PLC control program, so that the welding component 200 moves and performs welding operations on the DC power module according to the steps set by the PLC control program (the connection principle and steps between the welding component 200 and the PLC control program are existing technologies and will not be described in detail here). When the welding component 200 is controlled by the control program, the rotating seat 220 on the upper surface of the base 210 will first rotate... The left and right angles of the support arm are automatically adjusted. After adjustment, the angles of the support arm body 1 230 and support arm body 250 inside the support arm are automatically adjusted through the hinge of the rotating seat 220 and the hinge of the hinge seat 240, thereby achieving the final angle adjustment of the welding head 260 at the far end of the support arm. Then, the DC power module can be welded through the welding head 260, thus achieving multi-axis welding operation with synchronous movement in conjunction with the working component 100. Since the support arm is rotatably mounted on the base 210, the welding head 260 can rotate flexibly within a certain range. The angle and position of the welding head 260 can be easily adjusted according to the position of different welding points on the DC power module without moving the entire equipment or workpiece, which improves the flexibility and convenience of welding. It is especially suitable for welding DC power modules with complex shapes or layouts, and can accurately reach each welding part.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
