[0043] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0044] like Figure 3 As shown in the figure, it is a schematic diagram of the overall structure of the energy storage welding machine system with automatic loading and unloading functions of the utility model. For further information, please refer to Figure 4 (without automatic feeder), and Figure 5 (The loading device and unloading device are removed); the energy storage welding machine system with automatic loading and unloading functions of the utility model is provided with a servo rotating table 1, on which a fixture is provided, on which the workpiece to be welded or welded is placed, and the fixture divides the servo rotating table 1 into a number of workstations. There are 6 workstations in the attached drawings of this embodiment, namely, a sheet metal plate loading station 3, a nut installation station 4, an inspection station 5, a welding station 6, and 2 unloading stations 7.

[0045] An automatic feeding device 2 is provided beside the upper sheet metal station 3 and the nut installing station 4, including a conveyor belt feeding device 21, which spreads the sheet metal and feeds it one by one to the upper sheet metal station 3, and a vibration plate feeding device 22, which screens the nuts and feeds them one by one to the nut installing station 4.

[0046] The specific structure of the servo rotary table 1 is as follows Figure 6 As shown, it includes a truncated table 11 and a servo motor 12; the center of the truncated table 11 is installed on the output shaft of the servo motor 12, and the servo motor 12 rotates at equal intervals according to the number of workstations set on the truncated table 11, so that the truncated table 11 rotates at equal intervals, and the fixture located at the edge of the truncated table 11 is circulated between different workstations, realizing fully automatic loading, fully automatic welding, and fully automatic unloading.

[0047] On the truncated table 11 , different clamps, such as clamp 13 and clamp 14 , can be selected according to the shapes of the sheet metal plates to be welded.

[0048] like Figure 7 , Figure 8 As shown, the fixture has a mounting plate 131 and a positioning stud 132. The mounting plate 131 is mounted on the edge of the truncated table 11. The positioning stud 132 corresponds to the positioning hole on the truncated table 11 to fix the mounting plate 131 in a suitable position. A positioning column 133 is provided in the middle of the positioning plate 131, which has a positioning pin 1333. The positioning pin 1333 accurately passes through the hole on the sheet metal plate where the nut is to be welded, and at the same time accurately passes through the hole of the nut A to accurately position the sheet metal plate and the nut.

[0049] like Figure 7As shown, for a smaller sheet metal plate B, a support seat 134 and a locking column 135 can be set, and the support seat 134 is used to support the bottom surface of the sheet metal plate B so that the welding part remains horizontal; then the locking column 135 is passed through other holes on the sheet metal plate B to tighten and lock it.

[0050] like Figure 8 As shown, for the complex sheet metal plate C that can be clamped, a support seat 144 can be set to support the sheet metal plate C from both sides; elastic clips 145 are set at both ends of the support seat 144 to fix the sheet metal plate C through the elastic clips 145.

[0051] The upper sheet metal plate station 3 and the unloading station 7 are both for positioning, clamping and placing the sheet metal plate, so the same clamping device can be used, such as Fig. 9 , Fig.10 , Fig.11 As shown, its structure is similar to the copper foil soft connection production method and automated production system with Chinese Patent Publication No. CN114770033A, or the single-drive bidirectional transfer mechanism with Chinese Patent Publication No. CN216917683U and the "transfer mechanism" in its conveyor line.

[0052] The feeding side of the clamping device of the upper sheet metal station 3 is connected to the conveyor belt feeding device 21, and the discharging side corresponds to the clamp on the round table 11. The clamping device of the upper sheet metal station 3 clamps a sheet metal plate to be welded from the conveyor belt feeding device 21, and then transports it to the clamp on the round table 11, and the clamp locks the sheet metal plate.

[0053] The round table 11 is controlled to rotate at a fixed angle, and the fixture together with the sheet metal plate is rotated from the upper sheet metal plate station 3 to the nut installation station 4.

[0054] The nut installation station 4 is equipped with an automatic nut conveying device, such as Fig.12 As shown, its structure can refer to the single part delivery device for automatic welding machine with Chinese patent publication number CN215967074U. The vibration plate feeding device 22 continuously inputs the sorted nuts into the nut automatic conveying device, and then the nut automatic conveying device aligns the nut with the positioning pin 1333 on the fixture and places the nut on the sheet metal plate.

[0055] The round table 11 is controlled to rotate at a fixed angle, and the fixture together with the sheet metal plate and the nut is rotated from the nut installation station 4 to the inspection station 5.

[0056] Inspection station 5 is equipped with inspection devices, such as Fig.13 As shown, its structure can refer to a nut positive and negative detection mechanism for a welding machine with Chinese patent publication number CN208961302U. The state of the nut on the sheet metal plate is re-detected and confirmed.

[0057] The round table 11 is controlled to rotate at a fixed angle, and the fixture together with the sheet metal plate and the nut is rotated from the inspection station 5 to the welding station 6.

[0058] The welder in the welding station 6 works to weld and fix the nut to the sheet metal plate.

[0059] The round table 11 is controlled to rotate at a fixed angle, and the fixture together with the welded sheet metal plates and nuts are rotated from the welding station 6 to the unloading station 7.

[0060] The feeding side of the clamping device of the unloading station 7 corresponds to the clamp on the round table, and the discharging side is connected to the collection box or the conveyor belt, which is convenient for the centralized collection and output of the finished welding products. The clamping device of the unloading station 7 removes the welded sheet metal plate together with the nut on the clamp, and then puts it into the discharging side for centralized collection and discharging.

[0061] After the fixture has finished unloading at the unloading station 7, it is emptied; the round table 11 is controlled to rotate at a fixed angle, and then the empty fixture is rotated from the unloading station 7 to the upper sheet metal station 3. Repeat the operation.

[0062] In actual production, each workstation produces continuously, so that there are sheet metal plates and nuts to be welded in each production cycle of welding station 6, which improves the welding operation efficiency.

[0063] There are two unloading stations 7, each equipped with a set of clamping devices, corresponding to the discharge collection box or conveyor belt respectively; it can be collected differently according to different product types; or a finished product inspection unit is provided after the welding station 6 to inspect the finished products after welding. Qualified products are unloaded by one unloading station, and unqualified products are unloaded by another unloading station, and are respectively transported to different collection boxes or conveyor belts to realize the classified collection of finished products.
