Description

Technical Field

[0001] This application relates to linear motor mover production equipment, specifically to a mover magnetic pole detection device. Background Technology

[0002] The mover in a linear motor is the component responsible for generating linear motion. It typically consists of components such as guide rails, sliders, electromagnets, or coils. When energized, it generates a magnetic field that interacts with the constant magnetic field of the stator, thereby generating thrust to achieve precise displacement. This component can be considered an equivalent form of the rotor of a rotary motor after it has been unfolded. Its motion can be either a fixed primary (stator) moving the secondary (mover), or a fixed secondary moving the primary, depending on design requirements. Its working principle is based on the law of electromagnetic induction: when the mover coil is energized, it generates a variable magnetic field, which interacts with the stator magnetic poles (such as an alternating N / S array) through repulsion or attraction, driving the mover to move linearly along a predetermined trajectory.

[0003] During the manufacturing process of the mover, the magnetic pole detection of the mover uses a contact detection pen, which is slow and may cause problems with the detection sequence due to manual detection. Summary of the Invention

[0004] Therefore, it is necessary to provide a moving pole detection device to address the problems of existing technologies.

[0005] To address the problems in the existing technology, the technical solution adopted in this application is as follows:

[0006] A moving pole detection device includes a detection plate. Several first mounting slots are evenly spaced along the length of the detection plate on the lower surface of the detection plate. A Hall sensor is fixedly connected in each of the first mounting slots. A mounting plate is fixedly connected to the upper surface of one side of the detection plate. The mounting plate is vertically arranged. Several circuit boards are fixedly connected to the mounting plate. The Hall sensor is electrically connected to the circuit board. An indicator light is electrically connected to the circuit board. A limiting member is provided on the lower surface of the detection plate for limiting the position of the detection plate on the moving pole surface.

[0007] Preferably, the limiting member includes a first limiting plate fixedly connected to the side wall of the lower surface of the detection plate near the mounting plate and a second limiting plate fixedly connected to both ends of the lower surface of the detection plate, with the mover placed between the first limiting plate and the second limiting plate.

[0008] Preferably, a plurality of reinforcing plates are fixedly connected to one side of the upper surface of the detection plate, and the plurality of reinforcing plates are evenly spaced along the length of the detection plate, and the mounting plate is fixedly connected to the reinforcing plates.

[0009] Preferably, a plurality of mounting posts are fixedly connected to the mounting plate, and a shielding plate is fixedly connected to the mounting posts. The shielding plate is transparent.

[0010] Preferably, the shield is made of acrylic material.

[0011] Preferably, the detection plate is made of acrylic and is transparent.

[0012] Preferably, a connecting groove is formed on the upper surface of the detection plate, the connecting groove extends through the upper and lower surfaces of the detection plate, and one end of the first mounting groove is connected to the connecting groove.

[0013] Preferably, a second mounting slot is formed between two adjacent first mounting slots. The length of the second mounting slot is less than the length of the first mounting slot. One end of the second mounting slot is connected to a connecting slot. A Hall sensor is installed in the second mounting slot. Two rows of circuit boards are fixedly connected to the mounting plate. The two rows of circuit boards correspond one-to-one with the Hall sensors in the first mounting slot and the Hall sensors in the second mounting slot, respectively.

[0014] This application involves placing a processing detection plate on the surface of the mover, with two second limiting plates abutting against the end faces of the mover, and a first limiting plate abutting against one side wall of the mover. Hall sensors in the first and second mounting slots detect the magnetic poles at corresponding positions on the surface of the mover. When the correct magnetic pole is detected, an indicator light illuminates. This design is simple in structure and easy to operate, facilitating the operator's detection of the mover's magnetic poles and improving the efficiency of the operator's magnetic pole detection.

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] like Figure 1 , Figure 2 , Figure 3 As shown, a moving pole detection device includes a detection plate 1, which is made of acrylic material and is transparent. The detection plate 1 is rectangular and has several first mounting slots 2 evenly spaced along the length of the detection plate 1 on its lower surface. A second mounting slot 14 is formed between two adjacent first mounting slots 2, and the length of the second mounting slot 14 is less than the length of the first mounting slot 2. A Hall sensor 3 is fixedly connected to both the first mounting slot 2 and the second mounting slot 14. Three reinforcing plates 10 are evenly spaced along the length of the detection plate 1 on one side of the upper surface of the detection plate 1. A fixing plate is fixedly connected to the three reinforcing plates 10. Two rows of circuit boards 5 are evenly spaced along the length of the fixing plate and fixedly connected to the fixing plate. The two rows of circuit boards 5 correspond one-to-one with the Hall sensors 3 in the first mounting slot 2 and the Hall sensors 3 in the second mounting slot 14, respectively. Indicator lights 6 are electrically connected to the circuit boards 5.

[0021] like Figure 1 , Figure 2 , Figure 3 As shown, a limiting member 7 is provided on the lower surface of the detection plate 1. The limiting member 7 is used to limit the position of the detection plate 1 on the surface of the moving part. The limiting member 7 includes a first limiting plate 8 and a second limiting plate 9. The first limiting plate 8 is fixedly connected to the side wall of the detection plate 1 near the mounting plate 4. The second limiting plate 9 is provided in two pieces. The two second limiting plates 9 are respectively fixedly connected to the lower surfaces of both ends of the detection plate 1. The lower surface of the detection plate 1 abuts against the upper surface of the moving part. The two second limiting plates 9 abut against the end faces of both ends of the moving part. The first limiting plate 8 abuts against the side wall of one side of the moving part.

[0022] like Figure 1 , Figure 2 , Figure 3 As shown, in order to reduce the influence of the wire connecting the Hall sensor 3 and the circuit board 5 on the position of the detection board 1 on the moving surface, a connecting groove 13 is opened on the detection board 1. The connecting groove 13 passes through the upper and lower surfaces of the detection board 1, and the length direction of the connecting groove 13 is set along the length direction of the detection board 1. The connecting groove 13 is connected to one end of the first mounting groove 2 and one end of the second mounting groove 14.

[0023] like Figure 1 , Figure 2 , Figure 3 As shown, several mounting posts 11 are fixedly connected to the mounting plate 4. The mounting posts 11 are perpendicular to the mounting plate 4. A shielding plate 12 is fixedly connected to one end face of the mounting post 11. The shielding plate 12 is parallel to the mounting plate 4 and is vertically arranged. The shielding plate 12 is made of acrylic material and is transparent. The shielding plate 12 shields the circuit board 5.

[0024] The working principle of this embodiment is as follows: The operator holds the detection device and places it on the moving part. The detection plate 1 abuts against the upper surface of the moving part. The first limiting plate 8 and the second limiting plate 9 abut against the side wall of the moving part, respectively. The Hall sensor 3 in the second mounting groove 14 senses the S pole at the corresponding position on the moving part and the N pole at the corresponding position on the moving part. When the Hall sensor 3 senses the corresponding magnetic pole, the indicator light 6 on the corresponding circuit board 5 lights up. If the indicator light 6 on the corresponding circuit board 5 does not light up, it means that the magnetic pole on the surface of the moving part is incorrect.
