Description

Technical Field

[0001] This application relates to the field of thermistor manufacturing, and more specifically, to an automatic feeding device for the production of thermistors. Background Technology

[0002] With the rapid development of society and the economy, thermistors, a type of sensitive element, are classified into positive temperature coefficient thermistors and negative temperature coefficient thermistors according to their temperature coefficient. A typical characteristic of thermistors is their sensitivity to temperature, exhibiting different resistance values ​​at different temperatures. Positive temperature coefficient (PTC) thermistors have higher resistance values ​​at higher temperatures, while negative temperature coefficient (NTC) thermistors have lower resistance values ​​at higher temperatures. Both are semiconductor devices widely used in various industries. For example, Chinese patent application CN202121842882.8 describes a feeding device for the production of thermistors, comprising a conveyor belt with rolling cylinders at both ends. A central shaft is inserted between two of the rolling cylinders, and the central shaft is connected to a motor via a pulley and belt. Support columns are located at the front and rear ends of both sides of the outer surface of the conveyor belt. A scissor-type telescopic frame is located between the four support columns, connected by a movable shaft. A horizontal plate is located above the support columns, and a straight rod is located on one side of the horizontal plate. A spring surrounds the outside of the straight rod, and a mounting plate is fixedly attached to one side of the straight rod. Rollers are located on the inner wall of the mounting plate, and the rollers are slidably connected to the inner walls of slide rails located on both sides of a tray on the outer surface of the conveyor belt. The outer surface of the tray has grooves. This invention uses a clamping device to keep the thermistor stable during transmission, preventing it from slipping and being damaged.

Obviously, the described embodiments are only some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0027] Referring to Figures 1-4 , the present application provides an automatic feeding device for thermistor production, which comprises a feeding assembly 100 and an ejection assembly 200.

[0028] Referring to Figures 1-2 , the feeding assembly 100 comprises a conveyor body 110, a chain plate 120 and a concave plate 130. The chain plate 120 is arranged on one side of the conveyor body 110, and the concave plate 130 is arranged on one side of the chain plate 120. The conveyor body 110 is provided with four supporting legs 111 on one side, and the supporting legs 111 are provided with a bottom plate 112 at one end.

The concave plate 130 is provided with a plurality of cylinders 131 inside. The cylinders 131 are slidably connected with arc blocks 132 at one end. The cylinders 131 are provided with springs 133 inside. The springs 133 are fixedly connected with the arc blocks 132. The springs 133 and the arc blocks 132 can play a clamping role. The concave plate 130 is provided with limiting plates 134 at both ends inside. The limiting plates 134 can play a connecting role.

[0029] Referring to Figure 1 , Figure 3 and Figure 4 , the ejection assembly 200 comprises a supporting plate 210, a supporting seat 220, a tray 230 and an ejector 240. The supporting plate 210 is slidably connected with the concave plate 130. The supporting seat 220 is arranged on one side of the supporting plate 210. The tray 230 is arranged on one side of the supporting seat 220. The ejector 240 is arranged inside the supporting seat 220, and one end of the ejector 240 is slidably connected with the tray 230. The supporting plate 210 is provided with limiting grooves 211 at both ends. The limiting plates 134 are slidably connected with the limiting grooves 211. The supporting plate 210 is provided with a plurality of grooves 212 on one side. The arc blocks 132 are in contact with the grooves 212. The limiting plates 134 slide into the inside of the limiting grooves 211, and then the supporting plate 210 extrudes the arc blocks 132, so that the arc blocks 132 move into the inside of the cylinders 131. The spring force of the springs 133 makes the arc blocks 132 slide into the inside of the grooves 212, so that the supporting plate 210 can be fixed. Conversely, the supporting plate 210 can be disassembled and replaced.

[0030] In some specific embodiments, the tray 230 is provided with a placing groove 231 on one side for placing the thermistor, the ejector 240 comprises a counterweight 241 and a top rod 242, the counterweight 241 is slidingly connected with the inside of the support base 220, the top rod 242 is fixedly connected with the counterweight 241, and the top rod 242 is slidingly connected with the support base 220 and the tray 230. Due to the gravity, the counterweight 241 moves downward and drives the top rod 242 to move, so that the top rod 242 can eject the thermistor from the inside of the placing groove 231.

[0031] The working principle of the automatic feeding device for thermistor production is as follows: in use, the conveyor body 110 and the chain plate 120 can convey the thermistor inside the tray 230, when the thermistor is conveyed to the discharge end of the conveyor body 110, the plurality of longitudinal trays 230 are turned over, and the thermistor automatically slides out of the inside of the tray 230, without manually taking down the tray 230. Due to the gravity, the counterweight 241 moves downward and drives the top rod 242 to move, so that the top rod 242 can eject the thermistor from the inside of the placing groove 231 and fall into the receiving container, preventing the thermistor from being stuck in the placing groove 231. The limiting plate 134 slides into the inside of the limiting groove 211, then the support plate 210 extrudes the arc block 132, so that the arc block 132 moves into the inside of the cylinder 131, until the spring 133 makes the arc block 132 slide into the inside of the groove 212, so as to fix the support plate 210. Conversely, the support plate 210 can be disassembled and replaced, effectively saving labor and greatly improving production efficiency, thereby ensuring the continuity of production and improving the practicability.

[0032] It should be noted that the specific model and specification of the conveyor body 110 need to be selected and determined according to the actual specification of the device, and the specific selection calculation method adopts the existing technology in the art, so it will not be described in detail.
