[0026] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] A monolithic capacitor chip welding device according to an embodiment of the utility model is described below in conjunction with the accompanying drawings.

[0028] Reference Figure 1 A monolithic capacitor chip welding device according to an embodiment of the utility model includes a conveying mechanism and a welding mechanism.

[0029] The conveying mechanism includes a traction component and a limiting component. The traction component is used to pull the braid 340 to move horizontally. The limiting component is arranged in the conveying direction of the braid 340 and is used to limit the conveying direction of the braid 340.

[0030] Therefore, the traction component can pull the tape 340 to move horizontally and can transport the chip 330 to the welding station. The limiting component can limit the conveying direction of the tape 340 to prevent the chip 330 from deviating from the welding station, thereby providing a basis for welding the pin line 320 and the chip 330.

[0031] In some embodiments of the present invention, the traction assembly includes a first traction wheel 250, a second traction wheel 260, and a motor driving the first traction wheel 250 or the second traction wheel 260 to rotate. The first traction wheel 250 and the second traction wheel 260 pull the braid 340 in the horizontal direction.

[0032] It is understandable that the radial outer surface of the first traction wheel 250 is provided with a plurality of pins, which can be inserted into the holes of the braid 340. Therefore, when the first traction wheel 250 rotates, it can drive the braid 340 to move, thereby transporting the chip 330 to the welding station.

[0033] In some embodiments of the present invention, the limiting assembly includes a first limiting member 220 and a second limiting member 230 connected to each other, and a U-shaped limiting channel 240 is formed between the first limiting member 220 and the second limiting member 230. The limiting channel 240 accommodates the braid 340 to pass through, and the first limiting member 220 and the second limiting member 230 are connected by bolts.

[0034] Therefore, when the braid 340 enters the limiting channel 240, the first limiting member 220 and the second limiting member 230 can limit the braid 340 in the horizontal direction to prevent the chip 330 from deviating from the welding station during the conveying process.

[0035] Moreover, the U-shaped limiting channel 240 can also limit the upward movement of the braid 340, which facilitates the subsequent welding of the chip 330.

[0036] In some embodiments of the present invention, the first limiting member 220 is provided with an adjustment frame 270 , the adjustment frame 270 is provided with a waist-shaped hole 280 , an adjustment bolt 290 is connected between the adjustment frame 270 and the frame 180 , and the waist-shaped hole 280 accommodates the adjustment bolt 290 .

[0037] Therefore, the adjustment frame 270 can adjust the position by using the waist-shaped hole 280 to change the position of the limiting component, thereby ensuring that the chip 330 is located directly above the tin furnace 110 and ensuring that the chip 330 is normally soldered.

[0038] The soldering mechanism includes a lifting assembly and a tin furnace 110. The tin furnace 110 is used to solder the chip 330. The lifting assembly is connected to the tin furnace 110. Figure 2 and Figure 3 The tin furnace 110 includes a furnace body 120 located below the braid 340, a heater 130 arranged in the furnace body 120, the top of the furnace body 120 is open, and the furnace body 120 is filled with tin liquid. The lifting component includes a first cylinder 140 that drives the furnace body 120 to rise and fall. The furnace body 120 rises to allow the chip 330 to be immersed in the tin liquid.

[0039] Therefore, the heater 130 in the tin furnace 110 can heat the tin liquid to make the tin liquid reach the required temperature, the lifting component uses the first cylinder 140 to drive the furnace body 120 to rise, and the traction component suspends the conveying of the tape 340 to allow the pin wire 320 with the chip 330 to be inserted into the tin liquid, and the capacitor chip 330 is welded in large quantities to improve the welding efficiency. In addition, the time for the pin wire 320 with the chip 330 to be inserted into the tin liquid for welding can be set as needed to ensure that there is no problem of cold soldering and improve the welding quality.

[0040] In some embodiments of the utility model, a tin scraping mechanism is also included, which includes a scraper 150 and a second cylinder 160 that drives the scraper 150 to move horizontally. The scraper 150 is located in the furnace body 120 and can move horizontally from one side of the inner wall of the furnace body 120 to the other side.

[0041] It should be noted that the second cylinder 160 drives the scraper 150 to scrape the tin slag on the surface of the tin liquid from one side of the inner wall of the furnace body 120 to the other side, so as to prevent the welding point of the chip 330 and the lead line 320 from contacting the tin slag and causing cold soldering, thereby reducing the occurrence of defective products.

[0042] In some embodiments of the present invention, referring to Figure 2 , further comprising a third cylinder 170, which is disposed on the frame 180, and the third cylinder 170 is connected to the second cylinder 160 to drive the second cylinder 160 to move up and down.

[0043] Therefore, before the tin furnace 110 rises, the third cylinder 170 can be used to drive the second cylinder 160 to rise, so that the scraper 150 rises synchronously, avoiding interference and damage between the tin furnace 110 and the scraper 150.

[0044] In some embodiments of the present invention, a collecting box 190 is provided on the side of the furnace body 120 close to the second cylinder 160 , and the collecting box 190 is used to collect tin slag. Therefore, excessive tin slag can fall into the collecting box 190 , which greatly reduces the tin slag in the tin furnace 110 .

[0045] In some embodiments of the present invention, referring to Figure 2 and Figure 3 Two extension rods 300 are provided on one side of the scraper 150 , and one end of the extension rod 300 away from the scraper 150 is connected to a connecting plate 310 , and the connecting plate 310 is connected to the telescopic end of the second cylinder 160 .

[0046] Therefore, the second cylinder 160 uses the extension rod 300 to connect the scraper 150, and the second cylinder 160 can adopt a specification with a shorter stroke, which is also beneficial to reducing the space occupied by the equipment.

[0047] In some embodiments of the utility model, a guide rod 200 is provided at the bottom of the furnace body 120, the first cylinder 140 is fixed to the frame 180, and a guide sleeve 210 is provided on the frame 180. The inner side of the guide sleeve 210 accommodates the guide rod 200 to pass through, thereby improving the stability of the lifting and lowering of the furnace body 120.

[0048] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0049] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
