Preferably, as shown in fig. 4 and 6, a through hole 02 is formed in a coil frame of the transformer, and in operation, two clamping heads 221 of a clamping finger 22 can enter the through hole 02 in a closed state, and then the clamping finger 22 opens the two clamping heads 221, so that the two clamping heads 221 are abutted against hole walls on two sides of the through hole 02 of the coil frame, thereby realizing clamping of the transformer.
As a preferred option, referring to fig. 4 to 6, the clamping heads 221 include a fixing portion 2211 for abutting against the coil holder and a clamping portion 2212 connected to the fixing portion 2211, the fixing portion 2211 is provided with a cavity 201 matching with the shape of the inner contour 01 of the coil holder, and the clamping portion 2212 of one clamping head 221 is provided with an inclined surface 202 extending in a direction away from the cavity 201 and in a direction away from the clamping portion 2212 of the other clamping head 221.

When the transformer is clamped by the clamping fingers 22, the limiting protrusion 2213 is abutted against the bottom end of the coil holder of the transformer, so that the transformer is effectively prevented from being separated from the clamping fingers 22 in the soldering process. The clamping head 221 has a simple and ingenious structural design, and is beneficial to improving the clamping stability of the clamping fingers 22, so that the soldering tin of the transformer is more accurate, and the soldering tin quality of the transformer is ensured.
Because there may be a certain difference in the size of the through hole 02 of each coil rack, in order to make the holding fingers 22 able to hold and stabilize each coil rack, in this technical solution, referring to fig. 6, the holding heads 221 are rotatably disposed on the finger fixing blocks 231 via the holding rotating shaft 2214, and an elastic member 2215 is disposed between the two holding heads 221. Specifically, the elastic member 2215 is a compression spring. When clamping the hole wall of the through hole 02 of the coil holder, the finger opening and closing driving device 23 drives the two clamping heads 221 to be away from each other by a certain distance, and at this time, the two clamping heads 221 rotate around the clamping rotating shaft 2214 under the elastic action of the elastic piece 2215, so that the clamping part 2212 of the clamping head 221 can be always clung to the hole wall of the through hole 02 of the coil holder; the design of the structure enhances the clamping force of the clamping head 221 on the transformer on one hand; on the other hand, tolerance compensation is performed on the size of the through hole 02 of each coil rack, so that the clamping fingers 22 can stably clamp each transformer, the soldering precision of the transformer is improved, and the soldering quality of the transformer is ensured.

The plurality of clamping heads 221 may be integrally formed with the finger fixing block 231, or may be detachably connected with the finger fixing block 231. The fixed block displacement driving device 232 adopts a finger cylinder.
In this embodiment, referring to fig. 2 and 3, the clamping assembly rotation driving device 24 includes two rotation shafts 241 fixedly connected to two ends of the clamping assembly 27, and a rotation shaft rotation driving device 242 for driving one of the rotation shafts 241 to rotate, where the two rotation shafts 241 are rotatably disposed on the clamping moving arm 21. Specifically, the rotation shaft rotation driving device 242 may be driven by a mechanism of a rotation motor and a coupling. In operation, the rotation shaft rotation driving device 242 drives one of the rotation shafts 241 to rotate, and then drives the clamping assembly 27 to rotate around the rotation shaft 241 on the clamping moving arm 21, thereby driving the transformer to rotate, so that pins on two sides of the transformer can complete the soldering process.
In this technical solution, referring to fig. 1 and 2, the moving arm multi-axis linkage driving device 25 includes a sliding plate 251 slidably disposed on the machine 2, a sliding plate 251 displacement driving mechanism 252 for driving the sliding plate 251 to move transversely, and a moving arm lifting driving mechanism 253 for driving the clamping moving arm 21 to lift, where the sliding plate 251 is located above the solder pot 3, and the clamping moving arm 21 is movably disposed on the sliding plate 251. Specifically, the displacement driving mechanism 252 of the sliding plate 251 and the lifting driving mechanism 253 of the moving arm can be driven by adopting a motor to cooperate with a screw rod, a nut and other mechanisms.
In practical application, the sliding plate 251 is slidably provided with a lifting block 254 in a vertical direction, the clamping moving arm 21 is fixedly connected to the lifting block 254, and the lifting block 254 is in driving connection with the moving arm lifting driving mechanism 253. When the clamping moving arm 21 is to be transversely moved, the sliding plate 251 is driven by the sliding plate 251 displacement driving mechanism 252 to move, and the movement of the sliding plate 251 drives the lifting block 254 to move, so that the clamping moving arm 21 is driven to transversely move; when the clamping moving arm 21 is to be lifted, the moving arm lifting driving mechanism 253 drives the lifting block 254 to lift, thereby driving the clamping moving arm 21 to lift. The multi-axis linkage driving device 25 for the movable arm has simple and compact structural design and stable and reliable operation, and is used for realizing multi-axis linkage of the clamping movable arm 21, so that the movement flexibility of the clamping assembly 27 is enhanced, the manual welding action can be simulated, the soldering process step of the transformer is realized, and the soldering quality of the transformer is effectively ensured.
In this technical solution, referring to fig. 2 and 7, the sliding plate 251 is provided with a tin dross remover 26, the tin dross remover 26 includes a tin scraping blade 261, a tin scraping blade fixing plate 262, and a tin scraping blade lifting driving device 263 for driving the tin scraping blade fixing plate 262 to lift, the tin scraping blade 261 is hinged to the tin scraping blade fixing plate 262, and a tin dross collecting box 31 is disposed on one side of the tin soldering furnace 3. Specifically, the tin scraping knife lifting driving device 263 is a driving cylinder; the tin-scraping blade 261 is hinged with the tin-scraping-blade fixing plate 262 by an elastic hinge or other elastic mechanism.
In practical application, the displacement driving mechanism 252 of the sliding plate 251 drives the sliding plate 251 to move, so as to drive the tin scraping knife 261 to move above the tin soldering furnace 3; then the tin scraping knife lifting driving device 263 drives the tin scraping knife fixing plate 262 to descend so that the tin scraping knife 261 reaches the tin scraping position of the tin soldering furnace 3; the sliding plate 251 displacement driving mechanism 252 drives the sliding plate 251 to move, so that the tin scraping knife 261 is driven to move from one side to the other side of the tin soldering furnace 3 until the tin scraping knife 261 scrapes the liquid surface of the whole tin soldering furnace, so that tin slag on the liquid surface is scraped and the tin slag is scraped and moved into the tin slag collecting box 31; through the structure that the tin scraping knife 261 is hinged to the tin scraping knife fixing plate 262, the tin scraping knife 261 moves in an inclined state in the tin scraping process, so that the knife surfaces of the tin scraping knife 261 can contact tin slag, the contact area of the tin scraping knife 261 and the tin slag is increased, the tin slag can be scraped completely by the tin scraping knife 261, and the tin scraping effect is improved; meanwhile, when the tin scraping blade 261 scrapes tin and leaves the soldering tin stove 3, the tin scraping blade 261 collides with the stove wall of the soldering tin stove 3, and at the moment, the tin scraping blade 261 swings to enable the tin scraping blade 261 not to cause splashing of tin liquid of the soldering tin stove 3 and damage the soldering tin stove 3 due to hard collision with the stove wall.

when the clamping assembly 27 moves to the upper part of the soldering tin furnace 3, the tin scraping knife 261 is reset, the probe lifting driving device 322 drives the liquid level probe 321 to descend, so that the lower end surface of the liquid level probe 321 is in contact with the liquid level to detect the liquid level of the soldering tin liquid, if the liquid level is different from the preset height, the external control system controls the tin supplementing device 33 to supplement tin to the soldering tin furnace 3, after the detection of the liquid level probe 321 is completed, the clamping moving arm 21 drives the clamping assembly 27 to descend, and then drives the transformer to descend, so that pins of the transformer are in contact with the soldering tin liquid to solder; after the soldering tin is finished, the clamping moving arm 21 drives the clamping assembly 27 to ascend and move to the upper side of the soldering flux furnace 4 again, at the moment, the clamping assembly rotation driving device 24 drives the clamping assembly 27 to reversely rotate by a certain angle so as to drive the transformer to rotate, so that the pins on the other side of the transformer face the soldering flux furnace 4, then the invention continuously repeats the operation actions of dipping soldering flux and soldering tin, and meanwhile, the solder slag remover 26 also repeatedly scrapes off the solder slag in the soldering flux furnace 3, so that the solder tin quality of the pins on the other side of the transformer is ensured;
