Description

Technical Field

[0001] The invention relates to a detection device, in particular to a detection device before the stator of a flat wire motor is twisted. Background Art

[0002] In the flat wire motor stator production process, flaring and twisting are two important process steps. The quality of flaring directly affects the qualified rate of twisting into the mold. Therefore, in the automated production line, the inspection after flaring and before twisting into the mold is particularly important, and it is also an important means for the automated production line to improve the production qualified rate. At present, the domestic flat wire automatic line inspection method is to add a manual inspection position after the flaring process, and use the inspection mold to manually inspect the quality of flaring. This method increases the labor cost in the automated production line, and the efficiency is relatively low, which is not conducive to automation; the other is to omit this process, and directly enter the twisting after flaring. The disadvantage of this is that the qualified rate is reduced, the cost is increased, and it is not conducive to equipment cost control. Summary of the invention

[0003] In order to solve the shortcomings of the above-mentioned technology, the present invention provides a flat wire motor stator pre-twisting detection device.

[0004] The technical solution of the present invention is: a pressure sensor is provided at the center of the base frame, linear bearings are provided around the base frame, a sliding rod slides in the linear bearings, the top of the sliding rod is fixedly connected to the upper plate, a detection mold is provided on the upper plate, a guide inner core is provided on the detection mold, and a pressure display cooperates with the pressure sensor and is fixedly connected to the base frame. Beneficial Effects

[0005] The flat wire motor stator card-issuing pre-twisting detection device is adopted, and a reasonable pressure range is set by the pressure sensor to detect the quality of the expansion. It can not only detect and shape the stator before twisting, but also detect the stator with poor expansion and re-trim it. It has the advantages of simple and effective operation and cost saving. BRIEF DESCRIPTION OF THE DRAWINGS

[0006] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0007] Figure 1 is a structural diagram; Figure 2 for Figure 1 AA section view; The numbers in the figure represent the names of the components: 1. Base frame; 2. Pressure sensor; 3. Linear bearing; 4. Sliding rod; 5. Upper plate; 6. Detection mold; 7. Guide core; 8. Pressure display. DETAILED DESCRIPTION

[0008] refer to Figure 1 , Figure 2 A flat wire motor stator card before twisting detection device, a pressure sensor 2 is provided at the center of a base frame 1, linear bearings 3 are provided around the base frame 1, a sliding rod 4 slides in the linear bearings 3, the top of the sliding rod 4 is fixedly connected to an upper plate 5, a detection mold 6 is provided on the upper plate 5, a guide inner core 7 is provided on the detection mold 6, and a pressure display 8 cooperates with the pressure sensor 2 and is fixedly connected to the base frame 1.

[0009] The steps of the working method are: The flat wire stator to be inspected after expansion is sent to the inspection mold 6 by a robot or other grasping method. The pressure sensor 2 senses the pressure and outputs the pressure value through the pressure display 8. It is automatically compared with the set pressure value. If the pressure value exceeds the set pressure value, the pressure display alarms, so that the robot automatically discharges the unqualified products, thereby automatically detecting the quality of the expansion and preparing for the stator torsion.
