[0002] Chip, also known as microcircuit, microchip, integrated circuit (IC), refers to a silicon wafer containing an integrated circuit. It is very small and is often a part of a computer or other electronic device. The use of chips requires chip packaging. Chip packaging is the shell used to install semiconductor integrated circuit chips. It has the functions of placing, fixing, sealing, protecting chips and enhancing electrical and thermal performance. Chip packaging is a bridge between the internal world of the chip and the external circuit. The contacts of the chip are connected to the pins of the package shell with wires, and the pins are connected to other devices through wires on the printed circuit board. Since the chip is too small, an automated sorting device is required.

[0003] Existing thermistor chip sorting devices often use machines to transport chips, and the chips are sorted manually during the transportation process. The chips themselves are small in size, and humans cannot accurately judge whether the chip thickness and weight meet the standards, resulting in a low chip sorting yield rate. In addition, the wires on the chips are relatively fragile, and the chips are easily damaged by humans during the sorting process, which increases the sorting cost.

[0004] Therefore, we designed a thermistor chip sorting device. Utility Model Content

[0012] Preferably, the plurality of sorting plates are linearly arranged along the driving direction of the conveyor belt, and the weight of the counterweight balls included in the plurality of counterweight assemblies gradually decreases along the arrangement of the sorting plates.

[0013] The beneficial effects of the utility model are:

DETAILED DESCRIPTION

[0024] Reference Figure 1-Figure 6 A thermistor chip sorting device comprises a sorting device body 1, a driving motor 2 and an electric telescopic rod 3. The output end of the driving motor 2 is connected to a conveyor belt 19. The conveyor belt 19 always transmits in the direction of the electric telescopic rod 3. An assembly rack 4 is installed on the sorting device body 1. A carrier frame 5 is fixedly installed on the assembly rack 4. A sensor 6 is arranged on the carrier frame 5. The carrier frame 5 is connected to a swing rod 8 through an electric rotating rod 7. The electric rotating rod 7 is located at the top of the carrier frame 5. The bottom end of the swing rod 8 is in an arc shape. The conveyor belt 19 is installed on the assembly rack 4. The swing rod 8 is located above the conveyor belt 19. The driving motor 2 is started to drive the conveyor belt 19 to move, and the thermistor chip is placed on the conveyor. On the belt 19, the thermistor chip follows the conveyor belt 19 to move in front of the carrier 5. There is a certain gap between the bottom end of the carrier 5 and the conveyor belt 19. The thermistor chip that meets the thickness standard will directly pass through the gap, and the thermistor chip that does not meet the thickness standard will be blocked by the carrier 5. At the same time, the thermistor chip that does not meet the thickness standard touches the sensor 6 while being blocked. The sensor 6 sends a signal to start the electric rotating rod 7 to rotate. The rotation of the electric rotating rod 7 drives the swing rod 8 to swing. The swing rod 8 pushes the thermistor chip that does not meet the thickness standard out of the device during the swinging process. The thermistor chips that do not meet the thickness standard are centrally processed by manually placing a box outside the sorting device main body 1.

[0025] A plurality of sorting plates 14 are rotatably connected to the main body 1 of the sorting device, a mounting block 9 is connected to the electric telescopic rod 3, an electric rotating shaft 11 is installed at the bottom of the mounting block 9, a balancing block 12 is connected to the electric rotating shaft 11, a plurality of scrapers 13 are installed on the balancing block 12, a detector 10 is installed at the top of the mounting block 9, circular holes are provided on both sides of the mounting block 9, a plurality of support rods 18 are installed on the main body 1 of the sorting device, the mounting block 9 moves on the support rods 18, the scrapers 13 are in a circular array, the thermistor chip that meets the thickness standard continues to move with the conveyor belt 19, the length of one end of the conveyor belt 19 is less than the main body 1 of the sorting device, and the thermistor chip falls off the conveyor belt 19 The thermistor chip falls onto the sorting plate 14. During the falling process, it will be scanned by the detector 10. The detector 10 will send a signal immediately when it detects the thermistor chip falling, and start the electric rotating shaft 11 to rotate. During the rotation process, the electric rotating shaft 11 drives the balancing block 12 to rotate synchronously, and the balancing block 12 drives the scraper 13 to rotate. At the same time, the electric telescopic rod 3 is turned on to make the electric telescopic rod 3 drive the mounting block 9 to move. During the movement, the mounting block 9 drives the rotating scraper 13 to move synchronously, thereby pushing the thermistor chip to move to different sorting plates 14, and under the action of the scraper 13, it moves to the offset position of the center of gravity of the sorting plate 14.

[0026] A fixing part 15 is fixed to the bottom of the sorting plate 14, and the fixing part 15 is rotatably connected to a telescopic rod 16, and the telescopic rod 16 is connected to the sorting device body 1. A counterweight assembly 17 is installed at the bottom of the fixing part 15, and the counterweight assembly 17 includes a suspension rod and a counterweight ball. A plurality of sorting plates 14 are linearly arranged along the transmission direction of the conveyor belt 19, and the weight of the counterweight balls included in the plurality of counterweight assemblies 17 gradually decreases along the arrangement of the sorting plates 14. The thermistor chip moves to the offset position of the center of gravity of the sorting plate 14, and applies pressure to the sorting plate 14. To flip the sorting plate 14, the sum of the pressure applied by the thermistor chip and the gravity applied by the counterweight ball needs to reach a certain amount. At this time, the sorting plate 14 flips so that the thermistor The chip falls, and starts from the thermistor chip falling from the conveyor belt 19 to the sorting plate 14. Because the weight of the counterweight ball increases, the pressure required for the flipping of the multiple sorting plates 14 distributed in sequence also decreases from large to small. The heavier thermistor chip will cause the sorting plate 14 to flip when it moves to the first sorting plate 14, while the lighter thermistor chip will not cause the first sorting plate 14 to flip, and thus continues to move under the action of the scraper 13 until the pressure of the thermistor chip and the gravity of the counterweight ball reach a certain amount, thereby achieving accurate sorting of thermistor chips of different weights and preventing thermistor chips from being damaged when they are manually sorted.

[0027] A plurality of collecting bins 20 are installed on the main body 1 of the sorting device. The collecting bins 20 are located below the sorting plate 14. The sorted thermistor chips fall into different collecting bins 20, and are manually processed for the next step.

[0028] The working principle of the utility model is as follows: an assembly frame 4 is installed on the sorting device body 1, a carrier frame 5 is fixedly installed on the assembly frame 4, a sensor 6 is arranged on the carrier frame 5, the carrier frame 5 is connected with a swing rod 8 through an electric rotating rod 7, a plurality of sorting plates 14 are rotatably connected to the sorting device body 1, a fixing part 15 is fixed at the bottom end of the sorting plate 14, a telescopic rod 16 is rotatably connected to the fixing part 15, the telescopic rod 16 is connected to the sorting device body 1, a counterweight assembly 17 is installed at the bottom end of the fixing part 15, the counterweight assembly 17 includes a suspension rod and a counterweight ball, the electric rotating rod 7 is turned on by the sensor 6 to drive the swing rod 8 to push the chips that do not meet the thickness standard out of the device, the sorting plate 14 and the counterweight assembly 17 cooperate to sort the chips of different weights, so as to realize the accurate sorting of the chips and also avoid the chips from being damaged during the sorting process.
