Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0024] With reference to Figures 1-4 An embodiment provided by the utility model: thermistor chip ribbon equipment, the upper side of carrier tape 16 is provided with a plurality of resistance to be measured 1, resistance to be measured 1 includes packaged chip and two pins connected with packaged chip, the front and rear sides of the middle part of carrier tape 16 are provided with base one 3, the top of base one 3 is fixedly connected with controller 4, the side close to carrier tape 16 of controller 4 is provided with camera one 5, the right side of base one 3 is fixedly connected with support plate 14, the top of support plate 14 is fixedly connected with fixed column 18, the outer wall of fixed column 18 is provided with dial piece 20, one end of dial piece 20 is arranged on the pin of resistance to be measured 1, the right side of rear base one 3 is fixedly connected with base three 6, the front side of base three 6 is provided with camera two 17, the bottom of base one 3 is fixedly connected with base 11, the right side top of base 11 is fixedly connected with base four 10, the top of base four 10 is provided with cylinder two 13, the output end of cylinder two 13 is fixedly provided with cylinder one 12, and the output end of cylinder one 12 is fixedly provided with support two 22.

[0025] In the embodiment, the resistance to be measured is taken out by the cylinder. Figure 1The front and back of the right and left are the direction, the cylinder 12 and the cylinder 13 are all rotating cylinders, which are prior art; the measured resistance 1 is driven by the carrier tape 16, passes through the base 3, and is captured by the camera 5, then the camera 5 transmits the signal to the controller 4 for identification, to determine whether the packaging chip of the measured resistance 1 is damaged or cracked; then the identified measured resistance 1 continues to move to the right side under the driving of the carrier tape 16, is captured by the camera 17, and is transmitted to the controller 4, to determine whether the pin of the measured resistance 1 is damaged or deformed; at the same time, the resistance of the measured resistance 1 is measured through the contact of the probe 20 and the pin of the measured resistance 1, to determine whether it is qualified; if the controller 4 determines that the packaging chip, the pin and the resistance value of the measured resistance 1 are unqualified, when the measured resistance 1 moves to the right side to the back of the cylinder 12, the output end of the cylinder 12 is extended, so that the bracket 22 passes through the packaging chip of the measured resistance 1, and the measured resistance 1 is pulled out from the carrier tape 16 through the extension of the output end of the cylinder 13, is rotated to the right side of the base 11 through the cylinder 13, and is poured out through the rotation of the cylinder 12, so that the detection of the resistance chip after the carrier tape is realized, and the defective products are prevented from flowing out.

[0026] With reference to Figures 2-3 The other end of the probe 20 is electrically connected with the controller 4, and the outer wall of the fixed column 18 is threadedly connected with the clamping column 19, and the clamping column 19 is fixedly connected to the outer wall of the fixed column 18 through the probe 20.

[0027] Specifically, the resistance of the measured resistance 1 can be measured by the controller 4 through the contact of the probe 20 and the pin of the measured resistance 1, so as to determine whether the measured resistance 1 is qualified; the probe 20 is a sheet of metal material with elasticity, so that when the measured resistance 1 passes through, the probe 20 can contact the pin of the measured resistance 1, and can restore the original state after the measured resistance 1 passes through; when the probe 20 loses elasticity, the probe 20 can be replaced by disassembling the fixed column 18, so that the convenience of the device is improved.

[0028] With reference to Figures 1-3 The left end of the rear probe 20 is arranged at the left side of the rear fixed column 18, the right end of the rear probe 20 is arranged at the rear side of the left pin of the measured resistance 1, the left end of the front probe 20 is arranged at the left side of the front fixed column 18, and the right end of the front probe 20 is arranged at the front side of the right pin of the measured resistance 1; the resistance value of the measured resistance 1 can be measured by the controller 4 through the contact of the front and rear probes 20 and the two pins of the measured resistance 1, so as to determine whether the resistance of the measured resistance 1 is qualified.

[0029] With reference to Figure 2The camera 5 and the packaged chip of the resistor under test 1 are on the same horizontal plane. Specifically, the front and rear cameras 5 take pictures of the front and rear sides of the packaged chip of the resistor under test 1, and the controller 4 determines whether the appearance of the packaged chip of the resistor under test 1 is damaged, thus realizing the detection of the appearance of the resistor under test 1.

[0030] Reference Figure 2 Camera 2 17 is located behind the pin of the resistor under test 1. Camera 2 17 takes pictures of the pin of the resistor under test 1, and the controller 4 determines whether the pin of the resistor under test 1 is deformed or damaged, thus realizing the detection of the pin of the resistor under test 1.

[0031] Reference Figure 4 A bracket 8 is installed at the bottom of cylinder 12. The output end of cylinder 2 13 is fixedly installed at the bottom of bracket 8. Bracket 2 22 is installed outside the packaged chip of resistor 1 under test. A barb 21 is fixedly connected to the rear end of bracket 2 22. A push rod 23 is installed on the rear side of cylinder 12. The rear end of push rod 23 is in front of resistor 1 under test.

[0032] Specifically, when the resistor under test 1 is determined to be unqualified, the extension of the output end of cylinder 12 drives the bracket 22 to the outside of the package chip of the resistor under test 1, forming a surround on the package chip of the resistor under test 1. The barb 21 prevents the resistor under test 1 from falling when it is pulled out. The rotation of cylinder 2 13 rotates the output end of cylinder 12 to the left and right. Then, through the rotation and retraction of cylinder 12, the push rod 23 abuts against the package chip of the resistor under test 1, causing the resistor under test 1 to fall, thus clearing the unqualified resistor under test 1.

[0033] Reference Figure 1 Rollers 11 and 2 are provided on both the front and rear sides of the left end of the carrier belt 16. A motor 2 is fixedly installed at the bottom of the roller 11, and the bottom of the motor 2 is fixedly connected to the base 11. Specifically, the rotation of the output end of the motor 2 drives the roller 12 to rotate, thereby realizing the movement of the carrier belt 16.

[0034] Reference Figure 1 The top of the base 10 is fixedly connected to a motor 9. There are four motors 9, which are distributed around the base 10. Rollers 7 are provided on both the front and rear sides of the right end of the carrier belt 16. The bottom of the rollers 7 is fixedly installed on the output end of the motor 9.

[0035] Specifically, when the unqualified resistor 1 needs to be removed, the output of motor 9 stops rotating, causing the rollers 7 on both sides of the carrier belt 16 to form a clamping force on the tape, which counteracts the upward force required to pull out the unqualified resistor 1, thus achieving the removal of the unqualified resistor 1.

[0036] Working principle: The rotation of the output terminals of motor 15 and motor 9 drives rollers 2 and 7 to rotate, causing the carrier tape 16 to move to the right. After passing the base 3 and being captured by camera 5, camera 5 transmits the signal to controller 4 for identification, determining whether the packaged chip of the resistor under test 1 is damaged or cracked. Then, the identified resistor under test 1 continues to move to the right under the drive of the carrier tape 16, is captured by camera 17, and transmits the signal to controller 4 to determine whether the pins of the resistor under test 1 are damaged or deformed. At the same time, the front and rear side levers 20 respectively contact the left and right side pins of the resistor under test 1 and measure the resistance of the resistor under test 1 to determine whether it is qualified. If the controller 4 determines that the packaged chip, pins, and circuit of the resistor under test 1 are damaged, the resistor under test is qualified. If any resistance value is unqualified, the unqualified resistor 1 will move to the right behind cylinder 12. The output end of cylinder 12 will extend, and bracket 22 will also extend, forming a surround around the packaged chip of the resistor 1. Then, through the extension of the output end of cylinder 23 and the clamping of the carrier tape 16 by roller 27, the resistor 1 will be pulled off the carrier tape 16. Then, by rotating the output end of cylinder 23, the output end of cylinder 12 will be turned to the left and right direction and placed on the right side of cylinder 12. Then, by rotating and retracting the output end of cylinder 12, the resistor 1 on bracket 22 will be inverted, and the push rod 23 will press against the packaged chip of the resistor 1, causing the resistor 1 to fall off. This realizes the detection of the tape-reel thermistor chip and prevents defective products from flowing out.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
