Description

Technical Field

[0001] The utility model application relates to the technical field of feeding mechanisms, in particular to a linear feeding mechanism for thermistor chips. Background Art

[0002] Thermistor chip is an electronic component designed and manufactured based on the characteristics of integrated circuits and thermistors. It has the characteristics of small size, light weight, and fast response speed. It is widely used in temperature measurement, temperature control, over-temperature protection and other fields. The working principle of thermistor chip is to judge the temperature by measuring the change of resistance value.

[0003] When thermistor chips are processed, the semi-finished products need to be fed through a feeding mechanism. Since thermistor chips need to be visually inspected during processing, unqualified products detected need to be separated. However, most existing linear feeding mechanisms do not have a separation structure, which greatly reduces the practicality of the feeding mechanism. Summary of the Invention

[0004] In order to solve the problem that the existing linear feeding mechanism for thermistor chips is inconvenient to separate defective products during use, the utility model provides a linear feeding mechanism for thermistor chips to solve the above problem.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A linear feeding mechanism for thermistor chips includes a conveyor and a conveyor belt. An electric push rod is provided on the outside of one side of the conveyor, and a connecting rod is fixed to the output end of the electric push rod. A blanking push plate is fixed to the side end of the connecting rod. A blanking port that cooperates with the blanking push plate is provided on the conveyor opposite to the blanking push plate. A side rail box is fixed to the side outside the blanking port. A laser sensor is provided on the conveyor on the side of the blanking push plate.

[0007] Furthermore, both sides of the blanking push plate are fixed with limit slide bars, and the limit slide bars are slidably sleeved with fixed sleeve blocks, and the fixed sleeve blocks are respectively fixed on both sides of the electric push rod.

[0008] Furthermore, the bottom surface of the blanking push plate is flush with the inner bottom surface of the side rail box, and the height of the side rail box is equal to the height between the top surface of the conveyor belt and the top surface of the conveyor.

[0009] Furthermore, a baffle is fixed to one end of the side rail box away from the conveyor, and a buffer rubber pad is glued and fixed to the side of the baffle close to the conveyor belt, and the height of the baffle and the buffer rubber pad is less than the height of the side rail box.

[0010] Furthermore, a guide plate is symmetrically provided on one side of the conveyor away from the unloading push plate, and the outer sides of the guide plates are rotatably connected to adjusting screws through bearings, and the two adjusting screws are threadedly sleeved inside the conveyor.

[0011] Furthermore, the bottoms of the two guide plates are both slidably fitted with the top surface of the conveyor belt, and the sides of the two guide plates away from the unloading push plate are both configured to be outward-expanding arcs.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. In the utility model, a laser sensor is combined with a pushing component. When a detection mechanism detects defective products, a signal is transmitted to the laser sensor. After identification by the laser sensor, the pushing component is operated to push the defective products into the side rail box, thereby separating the defective products. This solves the problem that the existing linear feeding mechanism for thermistor chips is inconvenient to separate defective products during use, and greatly improves the practicality of the feeding mechanism.

[0014] 2. In the present invention, the front guide assembly ensures that the thermistor chip can be aligned before moving on the conveyor belt during transportation, thereby ensuring that the thermistor chip can be accurately pushed into the side rail box when reaching the discharge outlet, further improving the practicality of the feeding mechanism.

[0020] In order to make the purpose, features, and advantages of this application more obvious and easy to understand, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the embodiments described below are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0021] Reference Figure 1 、 Figure 2 and Figure 3 , a linear feeding mechanism for thermistor chips, including a conveyor 1 and a conveyor belt 2, an electric push rod 3 is provided on the outside of one side of the conveyor 1, and a connecting rod 4 is fixed to the output end of the electric push rod 3, a blanking push plate 5 is fixed to the side end of the connecting rod 4, both sides of the blanking push plate 5 are fixed with a limit slide 7, and the limit slide 7 is slidably sleeved with a fixed sleeve 6, the fixed sleeve 6 is respectively fixed on both sides of the electric push rod 3, and a blanking port 14 cooperating with it is opened on the conveyor 1 on the opposite side of the blanking push plate 5, A side rail box 9 is fixed to the side 0 outside the unloading port 14, and a baffle 10 is fixed to the end of the side rail box 9 away from the conveyor 1, and a buffer rubber pad 11 is glued and fixed to the side of the baffle 10 close to the conveyor belt 2. The height of the baffle 10 and the buffer rubber pad 11 is less than the height of the side rail box 9. The bottom surface of the unloading push plate 5 is flush with the inner bottom surface of the side rail box 9. The height of the side rail box 9 is equal to the height between the top surface of the conveyor belt 2 and the top surface of the conveyor 1. A laser sensor 8 is provided on the conveyor 1 on the side of the unloading push plate 5.

[0022] Specifically, when unqualified products are detected, the signal is transmitted to the laser sensor 8. When the unqualified products reach the laser sensor 8, the laser sensor 8 detects it and transmits the signal to the controller. The controller controls the electric push rod 3 to operate. When the electric push rod 3 is running, the connecting rod 4 pushes the unloading push plate 5, so that the unloading push plate 5 moves toward the unloading port 14. At this time, the unqualified products are pushed into the side rail box 9 through the unloading port 14 under the push of the unloading push plate 5. Under the impact force of the push, the unqualified products hit the buffer rubber pad 11. Under the obstruction of the baffle 10 and the buffer rubber pad 11, the unqualified products can be collected inside the side rail box 9, thereby separating the unqualified products. The unqualified push plate 5 moves back to the side of the conveyor 1 under the movement of the electric push rod 3.

[0023] As an optimization solution, Figure 3As shown, guide plates 13 are symmetrically arranged on the side of the conveyor 1 away from the unloading push plate 5. The bottoms of the two guide plates 13 are slidably fitted with the top surface of the conveyor belt 2. The two guide plates 13 are arranged in an outward-expanding arc shape on the side away from the unloading push plate 5, and the outer sides of the guide plates 13 are rotatably connected to the adjusting screws 12 through bearings. The two adjusting screws 12 are threadedly sleeved inside the conveyor 1.

[0024] Specifically, when the feeding mechanism is needed, the distance between the two guide plates 13 is first adjusted according to the width of the thermistor chip. During adjustment, the adjusting screw 12 is rotated so that the adjusting screw 12 drives the guide plate 13 to move, and the thermistor chip can be guided by the guide plate 13.
