TECHNICAL FIELD

[0001] The present application relates to the technical field of motor detection equipment, in particular to a visual motor magnetic bottom inspection machine. BACKGROUND

[0002] Electric small motors are widely used in various electric toys, electric small household appliances, and are usually composed of a motor shell, a magnet inside the shell, a bow for fixing the magnet, and a rotor coil. When producing electric small motors, it is necessary to check them after each production link to check whether the operation of the production link is qualified. In the production of electric small motors, the magnet inside the motor and the bow for fixing the magnet need to be checked, including whether the number of magnets is two, whether the magnets are intact without cracks, whether there are broken magnets and other impurities, and whether the installation position of the bow meets the requirements. At present, in the production of electric small motors, the number of magnets, whether the magnets are intact without cracks, whether there are broken magnets and other impurities, and whether the installation position of the bow meets the requirements are mostly checked manually. Manual checking not only consumes manpower, but also has unstable factors. After a long time of manual checking, the physical strength, energy, patience and other factors of the workers are greatly tested. These factors may cause defective motors to be undetected, thereby affecting the product yield and causing unnecessary losses. SUMMARY

Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the protection scope of the present invention.

[0027] like Figures 1-7 The visual motor magnetic bottom inspection machine shown includes an operating table 1, on which four support columns 113 are mounted. A Y-axis module 2 is mounted on each support column 113. An X-axis module 3 is mounted on the Y-axis module 2. A Z-axis module 4 is mounted on the X-axis module 3. A material gripper 8 is mounted on the Z-axis module 4. A mounting plate 5 is also mounted on each support column 113. The mounting plate 5 is equipped with a production line 51, production line separators 52, and a material discharge detection device 53. The operating table 1 also includes an NG (Not From Good) station 6, a positioning mechanism 7, and a detection device 9. The Y-axis... The axis module 2 consists of a first cylinder 21 and a first slide rail 22 horizontally arranged at the top of the support column 1, with the first cylinder 21 and the first slide rail 22 arranged parallel to each other at the top of the support column 11; the X-axis module 3 consists of a second cylinder mounting platform 31 horizontally arranged between the first cylinder 21 and the first slide rail 22 and perpendicular to the first cylinder 21 and the first slide rail 22, and a second cylinder 32 on the second cylinder mounting platform 31; the Z-axis module 4 consists of a third cylinder mounting platform 41 vertically arranged on the second cylinder 32 and a third cylinder 42 on the third cylinder mounting platform 41.

[0028] In this embodiment, the first cylinder 21, the second cylinder 32, and the third cylinder 42 are all guide rail slide cylinders; one end of the second cylinder mounting platform 31 is set on the slide of the first cylinder 21, and the other end is mounted on the first slide rail 22; the second cylinder 32 is mounted on the second cylinder mounting platform 31, so that the second cylinder 32 can move on the first cylinder 21 and the first slide rail 22 under the drive of the slide of the first cylinder 21; the third cylinder mounting platform 41 is set on the slide of the second cylinder 32; the first cylinder 21, the second cylinder 32, and the third cylinder 42 are also provided with a drag chain 234, which is used to protect the power cords and other equipment of the first cylinder 21, the second cylinder 32, and the third cylinder 42.

[0029] In this embodiment, the material gripper 8 is vertically mounted on the moving end of the third cylinder 42; the material gripper 8 includes a gripper mounting frame 81 and four grippers 82 that are equidistantly mounted on the gripper mounting frame 81.

[0030] In this embodiment, it is worth noting that the material flow direction of the production line 51 is from the production line separator 52 to the discharge detection device 53. The mounting plate 5 is horizontally mounted on the support column 1 and perpendicular to the Y-axis module 2; the production line 51 is fixed to the mounting plate 5 by a bracket and is parallel to the mounting plate 5; the production line separator 52 is fixed to the mounting plate 5 by a bracket and is located directly above the material receiving end of the production line 51; a separator photoelectric gate 521 is also provided on the production line separator 52, and a blocking strip is also provided on the production line 51 directly below the production line separator 52; the discharge detection device 53 is fixed to the mounting plate 5 by a bracket and is located above the material discharging end of the production line 51, and a discharge photoelectric gate 531 is also provided on the discharge detection device 53.

[0031] It is worth noting that the detection directions of both the separator photoelectric gate 521 and the discharge photoelectric gate 531 are aligned with the production line 51. The separator photoelectric gate 521 is used to detect whether there is a motor to be tested on the production line 51 below the separator 52. If not, it controls the production line 51 to transport the motor; if so, it controls the production line 51 to stop transporting the motor. The discharge photoelectric gate 531 is used to detect whether there is a motor that has been tested on the production line 51 below the discharge detection device 53. If so, it controls the production line 51 to transport the inspected motor away; if not, it controls the material gripper 8 to place the inspected motor onto the production line 51.

[0032] In this embodiment, the NG station 6 includes several placement slots 61, a toggle rod 62 that is perpendicular to the placement slot and horizontally arranged above the placement slot, a toggle cylinder that is poweredly connected to the toggle rod and fixed below the placement slot, and an NG station photoelectric gate 63 at one end of the placement slot; the bottom of the placement slot at the end away from the NG station photoelectric gate 63 is hollowed out, and the toggle rod passes through the hollowed-out part of the 62 and is poweredly connected to the moving end of the toggle cylinder.

[0033] It is worth noting that the photoelectric gate 63 at the NG station is used to detect whether the slot on the placement slot 61 is full of motors. After detecting that the slot is full of motors, it prompts the operator to manually remove the motors from the NG station 6.

[0034] In this embodiment, the positioning mechanism 7 includes a positioning mounting plate 71, a positioning cylinder 72 on the positioning mounting plate 71, a toggle plate 73 powered by the positioning cylinder 72, a positioning photoelectric gate 74, and several positioning slots 75. The positioning mechanism 7 is used to accurately position the motor to be tested, and after positioning, it is picked up by the material gripper 8 and placed at the testing device 9 for testing.

[0035] It is worth noting that the positioning slot 75 should be set to match the required position when the detection device 9 takes pictures, so that the motor can be directly clamped after positioning.

[0036] In this embodiment, the detection device 9 is a light source camera, used to take pictures of the motor to be inspected. It is worth noting that when in use, the light source camera should also be connected to an image processing device so that it can recognize the pictures taken by the light source camera and thus identify whether the magnetic base of the motor is qualified.

[0037] In this embodiment, the operating platform 1 is equipped with a housing, which also includes a switch door 11, a material handling door 12, a power switch 13, an alarm light 14, and a cooling fan 15. The switch door 11 is equipped with a handle 16, a display 17, a touch screen 18, and operation buttons 19. Casters 112 and footrests 111 are also provided at the bottom of the operating platform 1. The material handling door 12 is used to open and remove the motors from the NG station 6. The display 17, touch screen 18, operation buttons 19, and power switch 13 are used to control the entire device. The alarm light 14 is used to sound an alarm, prompting manual removal of the motors if the photoelectric door 63 of the NG station detects that the slot 61 is full of motors.

[0038] In this embodiment, it is worth noting that the number of material grippers 82, separator photoelectric gates 521 and 531, positioning slots 75 and positioning photoelectric gates 74 of the positioning mechanism 7 should be the same, i.e., four. This ensures that every motor entering the inspection process is inspected; the distance between the grippers 82 of the material grippers 8 and the distance between the positioning slots 75 of the positioning mechanism 7 should be the same to ensure that the detection device can take accurate pictures.

[0039] When using this vision motor magnetic bottom inspection machine, first connect production line 51 to the production line of the previous process, and ensure that the material flow direction of production line 51 is from the production line divider 52 to the discharge detection device 53. Then start the entire device to perform the motor magnetic bottom inspection. First, the motor moves on the assembly line 51 and is blocked by the blocking bar on the assembly line directly below the separator bar 52. At this time, the motors will be arranged and piled up on the assembly line 51. When all four separator bar photoelectric gates 521 detect a motor to be tested on the assembly line 51, the assembly line 51 is controlled to stop conveying the motor. Then, the material gripper 8 picks up the motor. After the motor is picked up, the assembly line 51 continues to convey the motor. The material gripper 8 picks up the motor and places it into the positioning groove 75 on the positioning mechanism 7. After the positioning photoelectric gate 74 detects the motor, the positioning cylinder 72 drives the actuating plate 73 to accurately position the motor. After positioning is completed, the material gripper 8 picks up the motor and places it above the detection device 9 to take a picture for inspection. The image processing device analyzes the magnetic base of the motor based on the picture result and outputs the result to the material gripper 8. If the material gripper... If any motors on station 8 are found to be defective, the material gripper 8 is moved above the NG station 6 to place the defective motors into the placement trough 61. Then, the qualified motors are placed onto the conveyor line 51 below the discharge detection device 53. At this time, the material gripper 8 picks up the next batch of motors to be inspected. When the discharge photoelectric gate 531 detects a motor, the conveyor line 51 is controlled to transport the inspected motors away. After the material gripper 8 places the defective motors into the placement trough 61, the actuating cylinder in station 6 controls the actuating rod 62 to move the defective motors toward the NG station photoelectric gate 63 to arrange them neatly. When the NG station photoelectric gate 63 detects a motor, it indicates that the trough on the placement trough 61 is full of motors, and the alarm 14 sounds, prompting the operator to manually remove the motors from station 6.

[0040] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., within the spirit and principles of the present invention should be included within the protection scope of the present invention.
