Description

[0002] At present, in the new energy CCS industry, in the process of laser welding nickel sheets and aluminum bars, a laser welding jig designed specifically for the product is usually used to achieve compression to prevent cold welds. The jig is divided into two parts: a bottom mold and an upper cover, which are hinged by a hinge structure and can be opened and closed. The upper cover is designed with an elastic welding window pressure block structure according to the position of the product nickel sheet. When the jig is closed, the welding window pressure block presses the nickel sheet.
[0003] The design of the fixture cover is complex, and a corresponding number of welding window block structures need to be designed according to the nickel sheets of the product. As the number of nickel sheets of the product increases, the fixture cost and precision requirements increase.
[0004] The elasticity of the welding window pressing block is achieved by the spring inside the welding window structure. As the number of uses increases, the spring has the risk of failure, which affects the pressing effect of the welding window pressing block. The nickel sheet and the aluminum bar are not pressed tightly, resulting in poor welding and cold welding, affecting the product yield.
[0005] Products with a large number of nickel sheets require a corresponding number of welding window pressing blocks. The elastic forces of multiple welding window pressing blocks accumulate and work together, making it difficult to press the upper cover together, increasing the labor intensity of the operators, reducing labor efficiency, and affecting production.

DETAILED DESCRIPTION
[0019] like Figure 1-2 As shown, the utility model provides a new energy CCS laser welding pressing head mechanism, including an installation vertical plate 1, an overlapping horizontal plate 2 arranged at the lower end of the installation vertical plate 1, a lower pressure plate arranged on the overlapping horizontal plate 2, a avoidance opening arranged on the lower pressure plate, and lower pressure columns 3 arranged on both sides of the avoidance opening. The installation vertical plate 1 and the overlapping horizontal plate 2 are symmetrically arranged in two groups, the lower pressure plate is arranged between the overlapping horizontal plates 2, and the avoidance opening and the lower pressure column 3 are located between the overlapping horizontal plates 2.
[0020] This design uses a pressure head mechanism instead of an upper cover, used in conjunction with a bottom mold. This design is installed on the lifting mechanism of the welding head in the laser welding equipment, without changing the structure of the original laser welding equipment. The two symmetrical mounting vertical plates 1 are fixed to the lifting mechanism and raised and lowered synchronously with the laser welding head. The position of the avoidance port corresponds to the laser welding head's laser beam trajectory. The position of the lower pressure column 3 corresponds to the position of the nickel sheet on the CCS product placed on the bottom mold. During use, the pressure head mechanism and the laser welding head are driven by the lifting mechanism to descend until the lower pressure column 3 presses against the nickel sheet. At this time, the laser beam generated by the laser welding head passes through the avoidance port and welds the nickel sheet and aluminum bar. This design eliminates the upper cover of the jig and retains the bottom mold. The pressure head mechanism is added to the original laser welding equipment, reducing the jig cost by more than 60%. When the laser welding head descends, it descends synchronously, and the nickel sheet and aluminum bar are pressed tightly by the lower pressure column, effectively avoiding false welds.
[0021] like Figure 1-2 As shown, one end of the overlapping horizontal plate 2 is fixed to the lower end of the mounting vertical plate 1, and the other end is horizontally cantilevered toward the inner side of the mounting vertical plate 1, and both ends of the lower pressing plate are respectively fixed to the cantilevered ends of the overlapping horizontal plate 2.
[0022] The laser welding head is located between the mounting vertical plates 1, which limits the specific fixed position of the overlapping horizontal plate 2 and the mounting vertical plates 1, increases the space between the mounting vertical plates 1, does not interfere with the laser welding head, and facilitates installation.
[0023] like Figure 1-2 As shown, a lap groove 4 is provided on the upper side of the overhanging end of the lap cross plate 2, and both ends of the lower pressing plate are respectively lapped in the lap groove 4 and fixed.
[0024] The overlapping groove 4 locates the installation position of the lower pressing plate and is fastened with bolts, which facilitates the installation of the lower pressing plate.
[0025] like Figure 1-2 As shown, it also includes a floating mechanism that is symmetrically arranged on two mounting vertical plates 1, and the floating mechanism includes an upper top plate 5 arranged at the upper end of the mounting vertical plate 1, a guide column 6 arranged at the lower end of the upper top plate 5, a baffle 7 arranged at the lower end of the guide column 6, a tightening spring 8 sleeved on the guide column 6, a floating plate 9 arranged on the inner side of the mounting vertical plate 1, a lower top plate 10 arranged at the upper end of the floating plate 9, and a guide hole arranged on the lower top plate 10. The floating plate 9 is slid up and down on the inner end surface of the mounting vertical plate 1, and the lower top plate 10 is sleeved on the guide column 6 above the baffle 7 with the help of the guide hole. The upper end of the tightening spring 8 is tightened to the upper top plate 5, and the lower end is tightened to the lower top plate 10. One end of the overlapping horizontal plate 2 is fixed to the lower end of the floating plate 9, and the other end is horizontally cantilevered toward the inner side of the mounting vertical plate 1.
[0026] The floating plate 9 is connected to the mounting vertical plate 1 by sliding up and down, the lower top plate 10 is connected to the guide column 6 by sliding sleeves, and the baffle 7 is located at the bottom of the guide column 6, limiting the lower top plate 10 on the guide column 6 to prevent it from detaching. Under the tightening action of the tightening spring 8, the lower top plate 10 is in a position where the lower end of the guide column 6 and the baffle 7 are tightly fitted. After the lower pressure column 3 on the lower pressure plate is pressed on the nickel sheet, the floating plate 9 moves up. Since the floating plate 9 and the lower top plate 10 are fixed, the lower top plate 10 will move up synchronously, causing the force of the lower pressure column 3 pressing on the nickel sheet to gradually increase until it reaches the preset downward pressure and stops. The design of the floating mechanism makes the force of the pressure head mechanism pressing the nickel sheet increase slowly and gradually, avoiding direct hard pressure and avoiding excessive force in a short period of time to cause damage, deformation or position displacement of the nickel sheet and the aluminum bar.
[0027] like Figure 1-2 As shown, one end of the upper top plate 5 is fixed to the upper end of the mounting vertical plate 1, and the other end is horizontally cantilevered toward the outside of the mounting vertical plate 1. A long hole is provided on the mounting vertical plate 1. One end of the lower top plate 10 is fixed to the floating plate 9, and the other end is cantilevered toward the outside through the mounting vertical plate 1 with the help of the long hole. The tightening spring 8 is located between the upper top plate 5 and the lower top plate 10 on the outside of the mounting vertical plate 1.
[0028] It is defined that the floating plate 9 is located on the inner side of the mounting vertical plate 1, and the upper top plate 5 and the lower top plate 10 are cantilevered to the outside of the mounting vertical plate 1, wherein the lower top plate 10 passes through the mounting vertical plate 1 with the aid of a long hole and does not hinder the lifting and lowering of the lower top plate 10, and the guide column 6, baffle 7, and tightening spring 8 are all located on the outside of the mounting vertical plate 1, further ensuring that the distance between the mounting vertical plates 1 is sufficient and does not affect the laser welding head.
[0029] like Figure 1-2As shown, a sliding mechanism is provided between the mounting vertical plate 1 and the floating plate 9, and the sliding mechanism includes a sliding rail 11 provided on the end surface of the mounting vertical plate 1, a slider 12 provided on the end surface of the floating plate 9, and a sliding groove provided on the slider 12 and adapted to the sliding rail 11, and the sliding rail 11 is embedded in the sliding groove of the slider 12 to form a sliding fit.
[0030] The sliding mechanism between the vertical plate 1 and the floating plate 9 is installed by the cooperation of the slide rail 11 and the slider 12, which has stable sliding and high connection strength.
[0031] like Figure 1-2 As shown, the upper and lower ends of the slide rail 11 are both provided with raised limit blocks 13 .
[0032] The limit block 13 can limit the lifting range of the slider 12 on the slide rail 11, and cooperate with the baffle 7 on the guide column 6 to limit the lowest and highest positions of the floating plate 9, making the operation more stable and safer.
[0033] like Figure 1-2 As shown, the lower pressure plate includes a left pressure plate 14 and a right pressure plate 15 which are respectively arranged on the overlapping cross plate 2 and correspond horizontally, and the avoidance opening includes a left slot 16 and a right slot 17 which are respectively arranged on the opposite ends of the left pressure plate 14 and the right pressure plate 15, and the lower pressure column 3 is provided with two groups, which are respectively arranged at the lower end of the left pressure plate 14 and located on both sides of the left slot 16 and at the lower end of the right pressure plate 15 and located on both sides of the right slot 17.
[0034] The lower pressure plate adopts a split design, which is composed of a left pressure plate 14 and a right pressure plate 15. It is more convenient to install and effectively avoids stress. The left notch 16 and the right notch 17 after splicing form an avoidance opening. The lower pressure column 3 adopts two groups, two in each group, which can press the nickel sheet in four directions, so that the nickel sheet is more evenly stressed and has a better fit with the aluminum bar after pressing.
