Detailed Description

Example one

As shown in fig. 1 to 6, a GDT pin soldering mechanism includes a driving mechanism 201 mounted on a platform 104 and electrically connected to a controller, wherein the driving mechanism 201 is used for driving a turntable 202 to rotate. A plurality of product clamps are annularly and uniformly distributed on the turntable 202, and are respectively used for clamping different products. In this embodiment, there are two product holders, four for each product holder, and the two product holders are arranged on the turntable 202 at intervals.

The welding mechanism is electrically connected with the controller, and a high-frequency welding coil 105 of the welding mechanism is arranged above the product clamp. And a second sensor 106 electrically connected with the controller is arranged on the platform, and the second sensor 106 is used for detecting whether the product clamp rotates to be aligned with the high-frequency welding coil 105 or not. When welding pins of a GDT, a product is placed in a corresponding product clamp, and then the turntable 202 is driven to rotate through the driving mechanism 201, so that the product clamp provided with the product moves to the position below the high-frequency welding coil 105 of the welding mechanism to weld the pins. When another type of GDT needs to be welded, a product is placed in another corresponding product clamp, and then the turntable 202 is driven to rotate by the driving mechanism 201, so that the product clamp provided with another type of product moves to the position below the high-frequency welding coil 105 to weld pins.

Specifically, the product clamp includes a fixed block 305 fixedly connected to the turntable 202 and a moving block 306 slidably mounted on one side of the fixed block 305. In this embodiment, the moving block 306 is mounted on the fixed block 305 side via a linear bearing. A spring is connected between the fixed block 305 and the moving block 306. A product cavity formed between the fixed block 305 and the moving block 306 of the product clamp corresponds to the product model.

The platform 104 is further provided with a material taking mechanism electrically connected with the controller, and the material taking mechanism is used for separating the fixed block 305 and the moving block 306 and enabling the product to fall off.

Specifically, the turntable 202 located below the moving block 306 is provided with a through hole 207. The lower end of the moving block 306 is provided with an extending block 307 extending to the lower part of the through hole 207. The material taking mechanism comprises a support 301 fixedly connected to the platform 104, a first air cylinder 302 electrically connected with the controller is fixedly connected to the support 301, and a shifting block 303 corresponding to the extending block 307 is fixedly connected to one end of a piston rod of the first air cylinder 302.

One side of the bracket 301 is provided with a first sensor 304 electrically connected with the controller, and the first sensor 304 is used for detecting whether the product clamp moves above the material taking mechanism. When the product clamp moves above the material taking mechanism, the rotating disc 202 stops rotating, the first air cylinder 302 drives the shifting block 303 to push the extending block 307, so that the moving block 306 is separated from the fixed block 305, the product in the product cavity is dropped, and the spring is in a stretching state at the moment. Then, the first air cylinder 302 drives the shifting block 303 to return, and the moving block 306 returns under the action of the elastic force of the spring. The turntable 202 is then driven to rotate again until the product pins on the next product clamp are welded, and then the product pins are moved to the position above the material taking mechanism, and then the product pins are dropped.

A collection box 308 is arranged on the platform 104 below the shifting block 303. The dropped product may fall into the collection box 308 for collection.

Example two

Further, a pressing mechanism electrically connected to the controller is installed on the turntable 202, and the pressing mechanism is used for pressing the product in the product clamp. After the product to be welded is placed on the product clamp, the product is pressed through the pressing mechanism, and waste products caused by displacement of the pin to be welded and the product can be avoided.

Specifically, the swaging mechanism includes a vertical rod 206 fixedly connected to the turntable 202, an upper plate 204 is mounted on the vertical rod 206, a plurality of second air cylinders 210 electrically connected to the controller are mounted at the lower end of the upper plate 204, and a pressing bar 211 is fixedly connected to one end of a piston rod of the second air cylinder 210.

The upper plate 204 is provided with a first arc-shaped hole 208, and the upper plate 204 is connected with the lower plate 203 through a bolt penetrating through the first arc-shaped hole 208. Since it is not necessary to install one second cylinder 210 on the lower disc 203 for each product clamp installed on the turntable 202, the number of the second cylinders 210 only needs to correspond to the number of a certain product clamp. In this embodiment, there are four product holders each, and thus the number of cylinders two 210 is only four. When another product needs to be welded, the bolts are loosened, the lower disc 203 is rotated, the second air cylinder 210 corresponds to the clamp of another product, and then the bolts are tightened, so that the position of the lower disc 203 is fixed.

The vertical rod 206 is provided with a hand-operated ball screw nut pair 205. The upper plate 204 is connected with a nut of a hand-cranking ball screw nut pair 205. Because the sizes of different models of products are different, the distance between the second cylinder 210 and the product clamp can be adjusted through the hand-operated ball screw nut pair 205, and therefore when products with different sizes are welded, the products can be firmly pressed by the pressing strip 211.
