Description

Technical Field

[0001] This utility model relates to the field of circuit board welding technology, specifically a positioning fixture for welding components. Background Technology

[0002] Soldering components onto a circuit board refers to the process of fixing electronic components onto a circuit board (PCB, printed circuit board) by soldering. This is a crucial step in electronic assembly, ensuring the electrical connection and mechanical fixation between electronic components.

[0003] Specifically, soldering involves melting solder and using its wettability and fluidity to tightly bond the pins of electronic components to the pads on a circuit board.

[0004] Current welding technology uses robots for precise positioning and handheld welding, but the process of loading the circuit board of the welding component carrier requires manual loading. The circuit board is replaced only after the robot has finished welding, which is time-consuming and inefficient. Utility Model Content

One of the high side plates is rotatably connected to a pulley via two rotating shafts. The two pulleys are connected by belt drive. The motor is installed on the outer side of the high side plate. The output end of the motor is connected to the adjacent rotating shaft. One side wall of the narrow loading plate is fixedly connected to the bottom side wall of the belt via a first connecting plate. One side wall of the wide loading plate is fixedly connected to the top side wall of the belt via a second connecting plate.

[0010] Preferably, the slide rail structure includes a slide rod, two short side plates are fixedly connected to the bottom of the base plate, and slide grooves are provided on the top of both the high side plate and the short side plate.

[0021] 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.

[0022] Please see Figure 1-4 The figure shows a positioning fixture for component welding, including a base plate 1 and a dual-station loading structure 2 on top. The dual-station loading structure 2 includes a wide loading plate 201 and a narrow loading plate 202. The wide loading plate 201 is located above the narrow loading plate 202. Both the wide loading plate 201 and the narrow loading plate 202 have positioning grooves 203 of the same size on their tops. A support plate 205 is provided below the narrow loading plate 202. Two parallel guide rails 208 are fixedly connected to the base plate 1 near its center. The guide rail plate 208 has a U-shaped guide groove 209 on its side. The bottom of the base plate 1 is fixedly connected to an arc-shaped support rod 207. The center of the support plate 205 has a guide cavity 2011. The bottom end of the arc-shaped support rod 207 passes through the guide cavity 2011 and is fixedly connected to a guide block 2010. The guide block 2010 is slidably connected to the U-shaped guide groove 209. A drive structure 3 for driving the movement of the dual-station loading structure 2 is installed on the base plate 1. Slide rail structures 4 are installed on the sides of both the wide loading plate 201 and the narrow loading plate 202.

[0023] It is worth noting that when the dual-station loading structure 2 needs to be moved, the drive structure 3 is activated, pulling the wide loading plate 201 and the narrow loading plate 202 to move alternately. The bottom end of the arc-shaped support rod 207 passes through the guide cavity 2011, and the bottom end is fixedly connected to the guide block 2010. The guide block 2010 is slidably connected to the U-shaped guide groove 209, which enables the narrow loading plate 202 to move up and down during the displacement process, and to pass smoothly under the wide loading plate 201 during the downward movement process. This allows the narrow loading plate 202 and the wide loading plate 201 to be used alternately, which can improve the overall work efficiency. While the robot is welding, the operator is picking up and putting down materials on the other side, realizing human-machine interaction to complete the entire welding process, thereby improving the overall efficiency.

[0024] Please refer to Figure 2 The base plate 1 has mounting holes 101 near its corners for fixing it stably to the workbench or other support structure. Several guide posts 206 are fixedly connected to the bottom of the narrow loading plate 202. The guide posts 206 slide through the support plate 205. The guide posts 206 guide and support the narrow loading plate 202, ensuring its stability during movement.

[0025] Please see Figure 2 Both the wide loading plate 201 and the narrow loading plate 202 have material picking notches 204 on the front side wall of the positioning groove 203. The material picking notches 204 make it easy for the operator to quickly pick up the circuit board that needs to be soldered when the narrow loading plate 202 and the wide loading plate 201 are used alternately, without the need for complicated operation process, which further improves work efficiency.

[0026] Please see Figure 2 , Figure 3 and Figure 4 The drive structure 3 includes a motor 301 and a belt 302. The top of the base plate 1 near the side is fixedly connected to a high side plate 401. One of the high side plates 401 is rotatably connected to a pulley 304 via two rotating shafts 305. The two pulleys 304 are connected by a belt 302. The motor 301 is installed on the outer side of the high side plate 401. The output end of the motor 301 is connected to the adjacent rotating shaft 305. One side wall of the narrow loading plate 202 is fixedly connected to the bottom side wall of the belt 302 via a first connecting plate 303. One side wall of the wide loading plate 201 is fixedly connected to the top side wall of the belt 302 via a second connecting plate 306.

[0027] After the motor 301 starts, its output drives the adjacent rotating shaft 305 and pulley 304 to rotate. Pulley 304 is connected to another pulley 304 via belt 302, causing belt 302 to circulate between the two pulleys 304. Since one side wall of the narrow loading plate 202 is fixedly connected to the bottom side wall of belt 302 via the first connecting plate 303, and one side wall of the wide loading plate 201 is fixedly connected to the top side wall of belt 302 via the second connecting plate 306, the rotation of belt 302 can drive the narrow loading plate 202 and the wide loading plate 201 to move. Driven by belt 302, the narrow loading plate 202 and the wide loading plate 201 can move smoothly on the base plate 1, achieving the purpose of alternating use.

[0028] Please see Figure 2 , Figure 3 and Figure 4 The slide rail structure 4 includes a slide rod 404. Two short side plates 403 are fixedly connected to the bottom of the base plate 1. The top of the high side plate 401 and the short side plate 403 are both provided with slide grooves 402. The bottom of the two side walls of the wide loading plate 201 and the narrow loading plate 202 are both fixedly connected with slide rods 404. The slide rods 404 are slidably connected to the slide grooves 402.

[0029] The slide bar 404 slides smoothly within the slide groove 402, ensuring the stable horizontal movement of the wide loading plate 201 and the narrow loading plate 202. The design of the slide groove 402 not only provides guidance for the slide bar 404, but also enhances the stability and load-bearing capacity of the entire positioning fixture through the slide rail structure 4. This allows the wide loading plate 201 and the narrow loading plate 202 to bear heavier components and maintain accurate positioning during component welding. Through the cooperation of the slide rail structure 4 and the belt drive mechanism, the smooth, rapid, and precise displacement of the wide loading plate 201 and the narrow loading plate 202 is achieved, improving the efficiency and accuracy of component welding.

[0030] 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.
