Technical Field
[0001] This utility model relates to the technical field of circuit board spot welding devices, specifically a circuit board spot welding device with strong continuity. Background Technology
[0002] A rotary multi-station spot welding device is an automated welding equipment that achieves multi-process cyclic operation through a rotating worktable. Its core advantage lies in using the circular motion of the turntable to sequentially transport circuit boards to different workstations, completing operations such as positioning, welding, and inspection, thereby achieving continuous and efficient spot welding operations. The rotary multi-station spot welding device consists of a servo motor, a reducer, a turntable surface, and positioning slots. Multiple circuit board fixed workstations are evenly distributed along the edge of the table surface. The accuracy of the turntable is controlled by an encoder or indexing mechanism to ensure that the positioning error during workstation switching does not exceed 0.1mm. However, in existing technologies, the rotating plates in some rotary multi-station spot welding devices are connected by welding or bolt holes, which makes it impossible to weld different circuit boards. This makes it difficult or inconvenient to disassemble the turntable, thus increasing downtime and time costs.
[0003] A circuit board spot welding device with strong continuity is proposed to solve the problems mentioned above. Utility Model Content
[0004] The purpose of this utility model is to provide a circuit board spot welding device with strong continuity, so as to solve the problem mentioned in the background art that in the existing technology, the rotating plate of some rotary multi-workstation spot welding devices is connected by welding or bolt holes, which makes it impossible to weld different circuit boards. This makes it difficult or inconvenient to disassemble the rotating plate, thereby increasing downtime and time costs.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a circuit board spot welding device with strong continuity, including a base, and a connecting frame is fixedly connected to one side of the top surface of the base; A rotating device is provided on the other side of the top surface of the base. A linear guide rail is fixedly installed inside the connecting frame. A sliding sleeve is slidably connected to the surface of the linear guide rail. An electric push rod is fixedly installed in the middle of the bottom surface of the sliding sleeve. A spot welding device is provided on the bottom surface of the electric push rod. A rotating groove is opened in the middle of the surface of the rotating device. A rotating column is rotatably connected in the middle of the rotating groove. Also includes: A rotating disk is connected through one side of the rotating column near the top, and several connecting components are arranged around the surface of the rotating disk. The connecting component includes a mounting bracket that is fixedly connected to the rotating disk; The fixed frame has a threaded rod that runs through the middle of its interior.
[0006] Preferably, a nut is threaded onto one side surface of the threaded insert, and one side surface of the nut is fitted and connected to the fixing frame.
[0007] Preferably, the threaded insert and nut are made of high-strength carbon steel.
[0008] Preferably, the rotating column has several fixing grooves around its surface near the top, and the fixing grooves are engaged with the threaded insert rod.
[0009] Preferably, a connecting column is rotatably connected inside the rotating groove, and the top surface of the connecting column is fixedly connected to the rotating disk.
[0010] Preferably, the top surface of the rotating disk has several pattern grooves around its perimeter.
[0011] Preferably, the rotating disk is made of engineering plastic.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This circuit board spot welding device with strong continuity, by setting a connecting component, which consists of a fixing frame, a threaded rod, and a nut, allows for easier and faster disassembly of the rotating disk compared to bolt holes, thereby reducing downtime and thus reducing time costs to a certain extent. The specific details are as follows: 1. By setting up connecting components, when disassembling and replacing the rotating disk, a tool is used to move the nut a certain distance on the threaded rod. Then, by pulling the threaded rod, the threaded rod separates from the fixing groove on the rotating column. This process is repeated until multiple connecting components are separated from the fixing groove, allowing the rotating disk to be disassembled and replaced. When installing the rotating disk, it is fitted onto the rotating column, with the connecting post at the bottom of the rotating disk located inside the rotating groove. After aligning the fixing groove with the threaded rod, the threaded rod is inserted into the fixing groove. Finally, the nut is rotated so that one side of the nut faces the fixing groove. The frame is pressed and fitted together, preventing the threaded rod from being pulled, thus enabling the rotating disk to be mounted on the rotating column. Compared to bolts and screw holes, the use of threaded rods and nuts makes disassembling the rotating disk simpler and more convenient. Simply unscrew the nut and pull out the threaded rod. Moreover, the threaded rod and nut can usually be replaced or repaired separately. If only the nut or threaded rod is faulty, it does not require repairing or remachining the entire screw hole as is the case with bolts and screw holes. This makes disassembling the rotating disk easier and can reduce costs to some extent. 2. By setting up a linear guide rail, a sliding sleeve, an electric push rod, and a spot welding device, when replacing the rotating disk, the linear guide rail is activated via the control terminal, causing the sliding sleeve to move. The movement of the sliding sleeve, in turn, moves the electric push rod and the spot welding device, allowing for position adjustment of the spot welding device. Simultaneously, the electric push rod is activated via the control terminal, causing the spot welding device to descend. Once the spot welding device is lowered to the appropriate position, the descent stops, facilitating the soldering of the circuit boards on the rotating disk. Attached Figure Description

[0015] 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.
[0016] Please see Figure 1-5 This utility model provides a technical solution: a circuit board spot welding device with strong continuity, including a base 1, a connecting frame 2 fixedly connected to one side of the top surface of the base 1; a rotating device 3 provided on the other side of the top surface of the base 1, a linear guide rail 4 fixedly installed inside the connecting frame 2, a sliding sleeve 5 slidably connected to the surface of the linear guide rail 4, an electric push rod 6 fixedly installed in the middle of the bottom surface of the sliding sleeve 5, a spot welding device 7 provided on the bottom surface of the electric push rod 6, a rotating groove 8 opened in the middle of the surface of the rotating device 3, and a rotating column 9 rotatably connected in the middle of the interior of the rotating groove 8; it also includes: a rotating disk 12 penetratingly connected to one side of the rotating column 9 near the top, and several connecting components 14 arranged around the surface of the rotating disk 12; wherein, the connecting component 14 includes a fixing frame 1401 fixedly connected to the rotating disk 12; wherein, a threaded insert rod 1402 penetratingly connected in the middle of the interior of the fixing frame 1401, such as Figure 1-5 As shown, by setting up a connecting component 14, which consists of a fixed bracket 1401, a threaded rod 1402, and a nut 1403, the cooperation between the threaded rod 1402 and the nut 1403 makes it easier and faster to disassemble the rotating disk 12 compared to bolt holes, thereby reducing downtime and reducing time costs to a certain extent. Meanwhile, the rotating device 3 is existing technology and its working principle and power connection are the same as existing technology. The rotating column 9 is fixedly connected to the rotating device 3, and the start of the rotating device 3 can drive the rotation of the rotating column 9. The spot welding device 7 is existing technology and its working principle and power connection are the same as existing technology. The linear guide rail 4 is model BGXH358E, and the electric push rod 6 is model LAM33-A. The linear guide rail 4 and the electric push rod 6 are electrically connected to the control end.
[0017] A nut 1403 is threaded onto one side of the threaded insert rod 1402. One side of the nut 1403 is fitted into the fixing bracket 1401. Both the threaded insert rod 1402 and the nut 1403 are made of high-strength carbon steel. Several fixing grooves 10 are formed around the top surface of the rotating column 9, and these grooves engage with the threaded insert rod 1402. Figure 3-5 As shown, when disassembling and replacing the rotating disk 12, by using a tool, the nut 1403 is moved a certain distance on the threaded rod 1402. Then, by pulling the threaded rod 1402, it is separated from the fixing groove 10 on the rotating column 9. By repeating the above operation, multiple connecting components 14 are separated from the fixing groove 10, and the rotating disk 12 can be disassembled and replaced. When installing the rotating disk 12, it is fitted onto the rotating column 9, so that the connecting post 11 at the bottom of the rotating disk 12 is located inside the rotating groove 8. Then, by connecting the fixing groove 10 and the threaded rod 1402... After the insertion rod 1402 is aligned, the threaded insertion rod 1402 is inserted into the fixed groove 10, and then the nut 1403 is rotated so that one side of the nut 1403 is pressed against the fixed frame 1401, so that the threaded insertion rod 1402 cannot be pulled, thus realizing the installation of the rotating disk 12 on the rotating column 9. At the same time, the threaded insertion rod 1402 and the nut 1403, which are made of high-strength carbon steel, have high strength and good toughness. After heat treatment, the hardness and wear resistance can be further improved, making them suitable for bearing large torque and axial load. In addition, to prevent rust and improve wear resistance, they can be galvanized, blackened, or nickel-plated.
[0018] A connecting column 11 is rotatably connected inside the rotating groove 8. The top surface of the connecting column 11 is fixedly connected to the rotating disk 12. Several model grooves 13 are formed around the top surface of the rotating disk 12, such as... Figure 4 As shown, the model slot 13 can hold the corresponding circuit board. The placement of the circuit board can be done manually or by a robotic arm. At the same time, the spot welding time of the spot welding device 7 on the circuit board is longer than the placement time of the circuit board, thereby ensuring continuous spot welding of the circuit board.
[0019] The rotating disk 12 is made of engineering plastic, specifically polyphenylene sulfide (PPS), which possesses outstanding high-temperature resistance, maintaining good mechanical properties and dimensional stability at high temperatures. It can withstand the heat generated during spot welding and is not easily deformed. It also exhibits excellent chemical corrosion resistance, resisting the erosion of various fluxes, cleaning agents, and other chemicals. Furthermore, PPS has good flame retardancy, improving the safety of the device. In addition, it possesses excellent electrical insulation properties, preventing leakage problems on the circuit board during spot welding.
[0020] Working principle: Before using this type of continuous circuit board spot welding device, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 5 As shown, firstly, by setting the connecting assembly 14, when disassembling and replacing the rotating disk 12, by using a tool, the nut 1403 is moved a certain distance on the threaded rod 1402. Then, by pulling the threaded rod 1402, the threaded rod 1402 is separated from the fixing groove 10 on the rotating column 9. By repeating the above operation, after separating multiple connecting assemblies 14 from the fixing groove 10, the rotating disk 12 can be disassembled and replaced. When installing the rotating disk 12, the rotating disk 12 is fitted onto the rotating column 9, so that the connecting post 11 at the bottom of the rotating disk 12 is located inside the rotating groove 8. Then, after aligning the fixing groove 10 with the threaded rod 1402, the threaded rod 1402 is inserted into the fixing groove 10. Then, by rotating the nut 1403, the nut 1403 is moved a certain distance on the threaded rod 1402. One side of the 03 is pressed against the fixing bracket 1401, so that the threaded rod 1402 cannot be pulled, thus enabling the rotating disk 12 to be installed on the rotating column 9. At the same time, by using the threaded rod 1402 and nut 1403, compared with bolts and screw holes, when disassembling the rotating disk 12, it is only necessary to unscrew the nut 1403 and then pull out the threaded rod 1402. Relatively speaking, the operation is simpler and more convenient. Moreover, the threaded rod 1402 and nut 1403 can usually be replaced or repaired separately. If only the nut 1403 or the threaded rod 1402 is faulty, it is not necessary to repair or re-machine the entire screw hole as with bolts and screw holes. Therefore, the disassembly of the rotating disk 12 is more convenient and can also reduce the increase in cost to a certain extent.
[0021] Secondly, by setting up a linear guide rail 4, a sliding sleeve 5, an electric push rod 6, and a spot welding device 7, when replacing the rotating disk 12, the linear guide rail 4 is activated through the control terminal, causing the linear guide rail 4 to move the sliding sleeve 5. The movement of the sliding sleeve 5 can then move the electric push rod 6 and the spot welding device 7, allowing for position adjustment of the spot welding device 7. Simultaneously, the electric push rod 6 is activated through the control terminal, causing the spot welding device 7 to descend. When the spot welding device 7 is lowered to a suitable position, the descent stops, facilitating the soldering of the circuit board on the rotating disk 12.
[0022] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
