Description

Technical Field

[0001] The invention relates to the technical field of automation equipment, in particular to an automation equipment used for coil frame loose wire and resistance detection. Background Art

[0002] Motors are important basic products widely used in the field of automation. Small motors are divided into leaded motors and leadless motors according to the different ways of connecting the leads. Leaded motors are motors where the leads are directly connected to the corresponding terminals to provide current to the motor stator windings, which is the so-called direct connection method. Leadless motors are motors with only connector ports, and the leads are connected to the motor as a separate part through a matching interface, which is the so-called indirect connection method.

[0003] Whether it is the aforementioned leaded motor solution or the leadless motor solution, a pin is required, which is connected to the coil frame and is used to wrap the corresponding winding enameled wire. At present, during the assembly process, since the enameled wire is in a taut state and has a large tensile force, it is easy to break when the enameled wire is thin, resulting in a large number of defective enameled wires being broken during the production process and transportation, causing motor failure; therefore, the market currently ensures the product yield through multiple processes such as loosening the coil frame and testing the coil frame resistance. However, loosening the coil frame and testing the coil frame resistance are performed separately and independently, which will result in many production steps and complex structures, and low production efficiency.

[0004] At present, a probe method is used to perform resistance detection on the coil frame, which is easy to cause damage to the terminal on the coil frame and the probe itself.

[0005] Therefore, the present invention is studied and proposed in view of the above problems. Summary of the invention

[0006] The purpose of the present invention is to overcome the shortcomings of the prior art and provide an automated device for coil frame loosening and resistance detection. The device can detect the resistance of the coil frame while loosening the coil frame, and has the characteristics of high production efficiency, simplified structure, fewer production steps and a high degree of automation.

[0032] The following is combined with Figure 1-8 Embodiments of the present invention are described in detail.

[0033] like Figure 1-8The present invention shows an automated equipment for coil frame wire loosening and resistance detection, comprising a frame 1, the frame 1 being provided with a storage device 2 for storing a coil frame 21 to be loosened, the frame 1 being provided with a wire loosening device 3 which can move relative to the frame 1 and can loosen the wire of the coil frame 21 and is located on one side of the storage device 2, the wire loosening device 3 comprising a pressing piece 31 which is provided on the frame 1 and can move relative to the coil frame 21 and press the pin 211 on the coil frame 21, the frame 1 being further provided with a driving component 32 which can drive the pressing piece 31 to move relative to the coil frame 21, the frame 1 being provided with a probeless detection device 4 which can detect whether the resistance of the coil frame 21 is good. When the coil frame 21 is loosened and the resistance is detected, the driving component 32 drives the pressing piece 31 to move relative to the coil frame 21, so that the pressing piece 31 presses the pin 211 on the coil frame 21 and causes the pin 211 to retract to loosen the wire. At the same time, the probe-free detection device 4 can perform resistance detection on the coil frame. Therefore, the present invention can detect the resistance of the coil frame while loosening the wire of the coil frame, and has the characteristics of high production efficiency, simplified structure, fewer production steps and high degree of automation.

[0034] like Figure 1-8 As shown, the probeless detection device 4 includes a glass fiber board 41 and an electrode terminal 42 disposed on the glass fiber board 41 and capable of detecting whether the resistance of the coil frame 21 is good. The glass fiber board 41 and the top pressure piece 31 are integrally formed. When the coil frame 21 is loosened and the resistance is detected, the coil frame can be loosened and the resistance is detected at the same time, which has high work efficiency and reduces work steps. At the same time, the probeless method is used to detect the resistance, which can prevent the coil and the pin wound on the coil frame from being damaged. The electrode terminal 42 is embedded and fixed on the glass fiber board 41.

[0035] In one embodiment, the driving component 32 includes a first telescopic cylinder 321 disposed on the frame 1, and a push rod 322 capable of pushing the storage device 2 to slide relative to the frame 1 is connected to the cylinder rod of the first telescopic cylinder 321. When the push rod 322 pushes the storage device 2 to slide, the pin 211 on the coil frame 21 on the storage device 2 touches the top pressure piece 31 to complete the retraction of the pin 211 to loosen the wire. During the wire loosening resistance detection, the first telescopic cylinder 321 drives the push rod 322 to move toward the side of the storage device 2, so that the push rod 322 pushes the storage device 2 to slide relative to the frame 1 toward the top pressure piece 31, and then the top pressure piece 31 touches the pin 211 of the coil frame 21 on the storage device 2 to complete the retraction of the pin 211, that is, the wire loosening work is realized on the coil frame 21, and at the same time, the electrode terminals on the fiberglass board perform resistance detection on the coil frame, such as Figure 1-4 shown.

[0036] In other embodiments, the driving component 32 includes a first telescopic cylinder 321 disposed on the frame 1, and the pressing member 31 is connected to the cylinder rod of the first telescopic cylinder 321. When the pressing member 31 is pushed by the first telescopic cylinder 321 and slides relative to the frame 1, the pressing member 31 presses the pin 211 on the coil frame 21 to cause the pin 211 to retract the loose wire. During the loose wire resistance detection, the first telescopic cylinder 321 pushes the fixed pressure member 31 to slide relative to the frame 1, that is, the pressing member 31 moves toward one end of the pin 211 of the coil frame 21, and the pressing member 31 presses the pin 211 on the coil frame 21 to cause the pin 211 to retract the loose wire. At the same time, the electrode terminals on the fiberglass board perform resistance detection on the coil frame 21, which is not shown in the figure.

[0037] Furthermore, a reset mechanism is provided between the storage device 2 and the frame 1, which enables the storage device 2 to be reset relative to the frame 1 when the driving component 32 is separated from the storage device 2 (not shown in the figure). When the storage device 2 is separated from the driving component 32, the storage device 2 can be reset relative to the frame 1, which has the characteristic of a high degree of automation.

[0038] According to design requirements, the reset mechanism is a reset spring arranged between the storage device and the frame.

[0039] Furthermore, the frame 1 is also provided with a rotating mechanism 5 that can rotate relative to the frame 1, and the storage device 2 is provided on the rotating mechanism 5 so that the storage device 2 rotates relative to the frame 1 along with the rotating mechanism 5. It is convenient for users to store the coil frame that needs to be loosened and tested for resistance on the storage device, and at the same time, the rotating mechanism 5 drives the storage device to move to the loosening position of the loosening device and the testing position of the probeless testing device so that the loosening device and the probeless testing device can loosen and test the resistance of the coil frame on the storage device, which has the characteristics of high production efficiency and high degree of automation.

[0040] According to the design requirements, the rotating mechanism 5 includes a rotating disk 51 provided on the frame 1 and a driving motor or motor 52 for driving the rotating disk 51 to rotate, and the rotating disk 51 is provided with a connecting portion 511 for connecting with the storage device 2. During operation, the driving motor or motor 52 works to drive the rotating disk 51 to rotate relative to the frame 1, so that the storage device storing the coil frame to be loosened and the resistance detection is rotated to the loosening station of the loosening device and the detection station of the probeless detection device so that the loosening device and the probeless detection device can loosen the coil frame on the storage device and detect the resistance.

[0041] like Figure 1-4As shown, the frame 1 is provided with a defective unloading mechanism 6 capable of unloading defective coil frames 21 on the storage device 2. When the coil frames 21 undergo the wire loosening and resistance detection processes and a defective coil frame appears, the defective unloading mechanism 6 operates and unloads the defective coil frame from the storage device 2, which has the characteristics of high degree of automation.

[0042] like Figure 1-4 As shown, the defective product unloading mechanism 6 includes a second telescopic cylinder 61 which is arranged on the frame 1 and can be telescopically movable up and down relative to the frame 1, the cylinder rod of the second telescopic cylinder 61 is connected to a third telescopic cylinder 62 which can be telescopically movable left and right relative to the frame 1, and the cylinder rod of the third telescopic cylinder 62 is connected to a unloading claw 63 which can unload the defective product coil frame 21 on the storage device 2. When a defective product coil frame appears, the second telescopic cylinder 61 works to drive the third telescopic cylinder 62 to move downward relative to the frame, that is, the third telescopic cylinder 62 moves toward the side of the storage device, so that the unloading claw 63 grabs or contacts the defective product coil frame 21, and then the third telescopic cylinder 62 moves to the left relative to the frame, that is, the unloading claw 63 moves to the side away from the storage device 2 and can unload the defective product coil frame 21 from the storage device 2.

[0043] According to design requirements, the number of the third telescopic cylinders 62 is multiple groups, and the multiple groups of third telescopic cylinders 62 are arranged at intervals on the cylinder rod of the second telescopic cylinder 61, and the corresponding air lever of each third telescopic cylinder 62 is provided with a discharge claw 63.

[0044] The frame 1 is also provided with a storage bin 7 for storing defective coil frames 21 when the defective coil frames 21 are removed from the storage device 2 by the defective coil unloading mechanism 6. When the defective coil unloading mechanism 6 removes the defective coil frames 21 from the storage device, the storage bin 7 can store and collect the defective coil frames 21, thereby preventing the defective coil frames 21 from being randomly placed, and is easy to use.
