Description

Technical Field

[0001] This utility model relates to the technical field of surge protector processing equipment, and more specifically to an automatic welding device for surge protectors. Background Technology

[0002] A surge protector is an electronic device that provides safety protection for various electronic devices, instruments, and communication lines. When a pulse overcurrent or overvoltage suddenly occurs in an electrical circuit or communication line due to external interference, the surge protector can conduct and divert the current in a very short time, thereby preventing the surge from damaging other equipment in the circuit. The key to the operation of a surge protector is the tripping of the spring contacts.

[0003] Current technology has shortcomings: The metal connectors and electrode plates of the surge protector are the core components of the surge protector. The metal connectors have solder pads. The soldering ends of the electrode plates are usually soldered to the solder pads by operators using a constant temperature soldering iron. Manual operation is prone to deviations such as soldering time and amount of solder. In addition, the high temperature of the soldering iron can easily cause work-related injuries.

A through groove 201 is provided on the top of the welding table 2 corresponding to the position of the heating block assembly 5. A metal connector 10 is movably connected to the inner side wall of the first fixing fixture 6, and an electrode plate 11 is movably connected to the inner side wall of the second fixing fixture 7. The through groove 201 is located at the center of the welding table 2. The operator places the metal connector 10 on the first fixing fixture 6. The electrode 11 is fixed in a first fixture 6 and then in a second fixture 7. The welding positions of the metal connector 10 and the electrode 11 are then tightly attached and aligned with the heating block assembly 5. The equipment is started to run the heating block assembly 5 and heat it to a suitable temperature. The operator controls the electric push rod 3 by stepping on a foot switch. The electric push rod 3 pushes the fixed base assembly 4 upward, so that the heating block assembly 5 is tightly attached to the bottom of the welding position between the metal connector 10 and the electrode 11. The operator places solder on the welding position between the electrode 11 and the metal connector 10. The heating block assembly 5 runs and heats the welding position, so that the solder melts and coats the welding position between the metal connector 10 and the electrode 11. After the welding is completed, the electric push rod 3 drives the heating block assembly 5 downward. The operator can then remove the electrode 11 and the metal connector 10.

[0015] The bottom plate 1 is fixedly connected to the top of the limiting post 8, and the top of the fixed seat assembly 4 is provided with a limiting hole 401. The side of the limiting hole 401 is movably connected to the side of the limiting post 8. When the fixed seat assembly 4 moves up and down, the limiting hole 401 slides along the limiting post 8 to ensure that the heating block assembly 5 moves in the vertical direction.

[0016] The heating block assembly 5 has an L-shaped structure and a bevel on its side to facilitate the heating block assembly 5 passing through the through groove 201 and contacting the welding joint of the metal connector 10 and the electrode sheet 11.

The inner side wall of the upper connecting plate 501 is movably connected to the side of the lower connecting plate 402. The side of the lower connecting plate 402 has a first mounting groove 403, and the side of the upper connecting plate 501 has a second mounting groove 502. The upper connecting plate 501 and the lower connecting plate 402 are fixed by bolts passing through the first mounting groove 403 and the lower connecting plate 402, for mounting the heating block assembly. The position of 5 is slightly adjusted laterally. According to the actual situation, during the installation of the heating block assembly 5, the second mounting groove 502 and the first mounting groove 403 are rectangular structures, so that the bolts can maintain a certain degree of mobility inside the second mounting groove 502 and the first mounting groove 403, so that the upper connecting plate 501 can move laterally in the first mounting groove 403, so that the heating block assembly 5 is aligned with the welding position of the metal connector 10 and the electrode plate 11. Then, the bolts are tightened to clamp the upper connecting plate 501 and the lower connecting plate 402 to realize the installation and fixation of the heating block assembly 5.

[0019] The working principle of this utility model is as follows: When assembling the equipment, loosen the bolts between the upper connecting plate 501 and the lower connecting plate 402, push the heating block assembly 5 to move the upper connecting plate 501 laterally along the first mounting groove 403, so that the heating block assembly 5 is aligned with the welding position of the metal connector 10 and the electrode plate 11. Then tighten the bolts to clamp the upper connecting plate 501 and the lower connecting plate 402 to realize the installation and fixation of the heating block assembly 5. Start the equipment to make the heating block assembly 5 run and heat to a suitable temperature. The operator controls the electric push rod 3 to run by stepping on the foot switch. The electric push rod 3 pushes the fixed base assembly 4 to move upward, so that the heating block assembly 5 is close to the bottom of the welding position of the metal connector 10 and the electrode plate 11. The operator puts solder on the welding position of the electrode plate 11 and the metal connector 10. The heating block assembly 5 runs to heat the welding position, so that the solder melts and wraps around the welding position of the metal connector 10 and the electrode plate 11 to complete the welding. After the welding is completed, the electric push rod 3 drives the heating block assembly 5 to move downward. The operator can then remove the electrode plate 11 and the metal connector 10.
