Description

Technical Field

[0001] This application relates to the field of welding technology, specifically a multi-point welding device. Background Technology

[0002] Welding, also known as fusion welding, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. There are many energy sources for modern welding, including gas flame, electric arc, laser, electron beam, friction and ultrasound. In addition to being used in factories, welding can also be carried out in a variety of environments, such as in the field, underwater and in space.

[0003] An existing patent (publication number: CN220029113U) discloses a multi-point welding device, including a worktable and a welding panel. A support frame is fixedly connected to the top of the worktable, and the welding panel is fixedly connected to the top of the support frame. A vertical shaft is fixedly connected to the left side of the top of the worktable, and a welding head is fixedly connected to the outside of the vertical shaft. An extension platform is attached to the right side of the welding panel, and a fixing block is fixedly connected to the bottom of the extension platform. A telescopic shaft is fixedly connected to the outside of the fixing block, and a bracket is fixedly connected to the other end of the telescopic shaft. In this invention, by using the extension platform, fixing block, telescopic shaft, and bracket, and with the bracket structure working in conjunction with the telescopic shaft to extend and open the extension platform, the extension platform can be rotated to different positions on the welding panel to provide stable support for multiple or large circuit boards, thereby maintaining the support method and improving the stability of the circuit board welding placement.

[0004] The aforementioned document provides stable support for the processed panel during use, but it generates dense smoke when welding the panel. The document lacks smoke control measures during welding, which can cause the smoke to affect the surrounding working environment. Furthermore, the smoke contains harmful substances that can negatively impact the health of the welding personnel. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a multi-point welding device that has advantages such as fume treatment and workpiece fixation, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: a multi-point welding device, comprising a body, the upper surface of which has a plurality of through holes arranged in a matrix, a dust collection frame inside the body that contacts the inner top wall of the body, a sliding plate above the body, a plurality of cylinders arranged at equal intervals mounted on the bottom surface of the sliding plate, a rod welded to the bottom end of each cylinder, two support plates above the body, a suction pipe mounted on the side of each of the two support plates that are close to each other, and a plurality of extraction cylinders arranged at equal intervals fixedly connected to the outer surface of each suction pipe;

[0007] The sliding plate is fixedly connected to two support plates. Each of the two support plates has a positioning contact plate below it. The upper surfaces of the two positioning contact plates are slidably inserted into the support plates adjacent to them. Two springs are fixedly connected to the upper surfaces of the two positioning contact plates. The other ends of the multiple springs are fixedly connected to the support plates adjacent to them.

[0008] The above solution allows the suction to be focused on the welding point of the workpiece by installing the dust collection frame and the through hole. The dust collection frame can also be moved according to the welding position, improving the overall practicality.

[0009] Furthermore, a support member is provided on the upper part of the machine body, and the support member is slidably connected to the machine body, while the dust collection frame is fixedly connected to the support member.

[0010] With the above solution, the dust collection frame can move with the support, allowing it to transfer the suction force for fume extraction to the welding position, thus concentrating the suction force at the welding position and facilitating the extraction of fume generated during welding.

[0011] Furthermore, the sliding plate is slidably connected to the inner wall of the support member.

[0012] With the above scheme, when the sliding plate slides inside the support, it can bring multiple welding rods close to the workpiece, and with the cooperation of multiple cylinders, it can achieve multi-point welding.

[0013] Furthermore, a hydraulic cylinder is installed on the bottom surface of the support member, and the output end of the hydraulic cylinder is fixedly connected to the upper surface of the sliding plate.

[0014] The above solution allows the installation of a hydraulic cylinder to push the sliding plate downwards, which in turn drives multiple welding rods to descend horizontally, facilitating welding operations on the workpiece.

[0015] Furthermore, both the left and right sides of the machine body are rotatably connected to lead screws, and the support member is threadedly connected to the two lead screws.

[0016] The above scheme allows the installation of lead screws to move the position of the support component during the rotation of the two lead screws, enabling it to cooperate with multiple cylinders and welding rods to perform welding work on different positions of the workpiece.

[0017] Furthermore, an extraction pump is installed on the inner wall of the machine body, and a telescopic tube is fixedly connected to the back of the extraction pump. The other end of the telescopic tube is fixedly connected to the dust collection frame.

[0018] The above solution allows for easy movement of the vacuum cleaner frame, ensuring that the vacuum cleaner frame and the extraction pump are always in communication.

[0019] Furthermore, a three-way pipe is fixedly connected to the front of the dust collection frame, and the other end of the three-way pipe is fixedly connected to two air extraction pipes.

[0020] The above solution allows for easy transmission of suction power, enabling the suction power inside the vacuum cleaner to be transmitted to the two extraction pipes.

[0021] Furthermore, pulleys are fixedly connected to the front ends of both lead screws, and the two pulleys are connected by belt drive. The front end of the lead screw on the left side is fixedly connected to the output end of an external servo motor.

[0022] The above scheme allows the pulley and belt to rotate synchronously, enabling the support to slide stably on the machine body.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] This multi-point welding device, through the cooperation of the dust collection frame and the through hole, facilitates the condensation of the adsorption force of the smoke and can transfer it, enabling it to extract smoke from different welding positions. The cooperation of the air extraction pipe and the extraction cylinder can treat the smoke above the welding position, thereby improving the overall practicality. The installation of the positioning contact plate and the cooperation of the spring can flexibly compress the workpiece, ensuring stable contact between the two workpieces and preventing the workpieces from swinging during welding, which would affect the welding quality.

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] Please see Figure 1 , Figure 2 and Figure 3 This embodiment of a multi-point welding device includes a body 1. The upper surface of the body 1 has multiple through holes 2 arranged in a matrix. Inside the body 1 is a dust collection frame 3 that contacts the inner top wall of the body 1. A sliding plate 4 is located above the body 1. Multiple cylinders 5 are installed at equal intervals on the bottom surface of the sliding plate 4. Each cylinder 5 has a welded rod 18 at its bottom end. Two support plates 6 are located above the body 1. Suction pipes 7 are installed on the side of each support plate 6 that is close to each other. Multiple extraction cylinders 8 are fixedly connected to the outer surfaces of the suction pipes 7. The combination of the dust collection frame 3 and the through holes 2 facilitates the condensation of the smoke and allows for its transfer, enabling the extraction of smoke from different welding positions. The combination of the suction pipes 7 and the extraction cylinders 8 also allows for the treatment of smoke above the welding position, thereby improving the overall practicality.

[0033] Please see Figure 1 , Figure 2 and Figure 3 The sliding plate 4 is fixedly connected to two support plates 6. Each of the two support plates 6 has a positioning contact plate 9 below it. The upper surfaces of the two positioning contact plates 9 are slidably inserted into the support plates 6 that are close to them. Two springs 10 are fixedly connected to the upper surfaces of the two positioning contact plates 9. The other ends of the multiple springs 10 are fixedly connected to the support plates 6 that are close to them. By installing the positioning contact plates 9 and the springs 10, the workpiece can be flexibly squeezed, so that the two workpieces can be stably contacted, and the workpieces can be prevented from swinging during welding between the two workpieces, which would affect the welding quality.

[0034] Please see Figure 1 , Figure 2 and Figure 3 A support member 11 is provided above the machine body 1. The support member 11 is slidably connected to the machine body 1. The dust collection frame 3 is fixedly connected to the support member 11. The dust collection frame 3 can move with the support member 11, so that it can transfer the suction force for fume extraction to the welding position, thereby concentrating the suction force at the welding position, which is convenient for extracting the fume generated during welding. The sliding plate 4 is slidably connected to the inner wall of the support member 11. When the sliding plate 4 slides inside the support member 11, it can bring multiple welding rods 18 closer to the workpiece, and with the cooperation of multiple cylinders 5, it can realize multi-point welding. A hydraulic cylinder 12 is installed on the bottom surface of the support member 11. The output end of the hydraulic cylinder 12 is fixedly connected to the upper surface of the sliding plate 4. The installation of the hydraulic cylinder 12 can push the sliding plate 4 down, so that the sliding plate 4 can move. Plate 4 can drive multiple welding rods 18 to descend horizontally, facilitating welding operations on the workpiece. Both sides of the machine body 1 are rotatably connected to lead screws 13. The support member 11 is threadedly connected to the two lead screws 13. The installation of the lead screws 13 can move the position of the support member 11 during the rotation of the two lead screws 13, enabling it to cooperate with multiple cylinders 5 and welding rods 18 to perform welding work on different positions of the workpiece. The front ends of the two lead screws 13 are fixedly connected to pulleys 17, and the two pulleys 17 are connected by belt drive. The front end of the lead screw 13 on the left side is fixedly connected to the output end of an external servo motor. The cooperation between the installation pulleys 17 and the belt enables the two lead screws 13 to rotate synchronously, thereby enabling the support member 11 to slide stably on the machine body 1.

[0035] Please see Figure 1 , Figure 2 and Figure 4 An extraction pump 14 is installed on the inner wall of the body 1. A telescopic tube 15 is fixedly connected to the back of the extraction pump 14. The other end of the telescopic tube 15 is fixedly connected to the dust collection frame 3. Installing the telescopic tube 15 facilitates the movement of the dust collection frame 3, so that the dust collection frame 3 and the extraction pump 14 are always in a connected state. A three-way tube 16 is fixedly connected to the front of the dust collection frame 3. The other end of the three-way tube 16 is fixedly connected to two suction tubes 7. Installing the three-way tube 16 facilitates the transmission of suction power, so that the suction power in the dust collection frame can be transmitted to the two suction tubes 7.

[0036] In this embodiment, a multi-point welding device, through the cooperation of the dust suction frame 3 and the through hole 2, facilitates the solidification of the adsorption force of the smoke and allows for its transfer, enabling the extraction of smoke from different welding positions. The cooperation of the air extraction pipe 7 and the extraction cylinder 8 can treat the smoke above the welding position, thereby improving the overall practicality. The cooperation of the positioning contact plate 9 and the spring 10 allows for flexible compression of the workpiece, ensuring stable contact between the two workpieces and preventing the workpieces from swinging during welding, which would affect the welding quality.

[0037] The working principle of the above embodiment is as follows: First, when welding workpieces on the machine body 1, the hydraulic cylinder 12 pushes the sliding plate 4 to descend horizontally within the support member 11. By setting multiple cylinders 5 and multiple welding rods 18, different welding rods 18 can be driven to weld sheet metal parts according to different welding requirements. When the sliding plate 4 descends, the two positioning contact plates 9 can contact the workpiece. Through the cooperation of the positioning contact plates 9 and the spring 10, the workpiece can be flexibly squeezed, ensuring stable contact between the two workpieces and preventing workpiece displacement during welding. The swaying motion affects the welding quality. At this time, the extraction pump 14 is activated and the suction is transmitted to the dust collection frame 3 through the telescopic pipe 15. At the same time, the suction can enter the two air extraction pipes 7 and the extraction cylinder 8 through the three-way pipe 16. The cooperation between the dust collection frame 3 and the through hole 2 can facilitate the condensation of the adsorption force of the smoke. The cooperation of the screw 13 can move the position of the support 11 so that it can extract the smoke from different welding positions. The cooperation between the air extraction pipe 7 and the extraction cylinder 8 can treat the smoke above the welding position, thereby improving the overall practicality.
