Description

Technical Field

[0001] This utility model relates to the field of relay frame detection technology, and in particular to a relay frame hole position detection machine. Background Technology

[0002] The relay frame serves as the core insulating and supporting component of the relay. For example... Figure 6-7 As shown, the relay frame 4 has a frame through hole 34 in the middle of its upper end face, and multiple pin holes 35 and multiple coil slot holes 36 are also provided on the lower end face of the relay frame 4. The machining accuracy of the frame through hole 34, coil slot holes 36, and pin holes 35 directly determines the assembly accuracy and electrical performance of the relay. Large deviations in hole size and position can lead to difficulties in pin assembly, coil winding misalignment, and even faults such as poor contact and short circuits.

[0003] Current relay skeleton hole position detection relies heavily on manual visual inspection or unidirectional imaging with a single camera, resulting in low detection efficiency and a high false judgment rate. After inspection, defective products also need to be manually sorted or separated through a single unloading channel, which easily leads to mixing with qualified products. Furthermore, it is impossible to classify and collect them according to defect type, which is not conducive to subsequent process improvement. Summary of the Invention

Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0025] The embodiments of this utility model relate to a relay skeleton hole position detection machine, such as... Figure 1-7 As shown, the system includes a workbench 1 and a vibratory feeder 3 installed on the left side of the workbench 1. An electric conveyor belt 2 is horizontally arranged on the upper end of the workbench 1, with its inlet end connected to the vibratory feeder 3.

Two hole position detection devices 8 are staggered on the front and rear sides of the electric conveyor belt 2 on the upper end of the workbench 1. A material distribution device 10 is installed on the electric conveyor belt 2 on the opposite side of each hole position detection device 8. The material distribution device 10 includes a material distribution slider. 22. A material distribution cylinder 23, a first baffle rod 25, a material distribution rod 26, and a pressure rod 28 are installed on the electric conveyor belt 2. A material distribution slider 22 and a material distribution cylinder 23 that controls the back-and-forth sliding of the material distribution slider 22 are installed on the material distribution slider 22. From left to right, a pressure rod 28, a material distribution rod 26, and a first baffle rod 25 are arranged on the material distribution slider 22. The pressure rod 28 is elastically connected to the material distribution slider 22. A material picking device 9 is provided at the rear end of the electric conveyor belt 2 on the right side of each hole detection device 8.

[0026] The electric conveyor belt 2 is equipped with a slide rail 21, and the material distribution slider 22 slides back and forth along the slide rail 21. The end of the slide rail 21 is equipped with a material distribution cylinder 23 that drives the material distribution slider 22.

[0027] The outlet end of the electric conveyor belt 2 is provided with a discharge hopper 5, which is arranged at an inclination.

[0028] The hole position detection device 8 includes a camera bracket 18 and a detection camera 19. The detection camera 19 is fixed on the worktable 1 by the camera bracket 18. A ring light source 20 is set at the upper end of the worktable 1 between the detection camera 19 and the electric conveyor belt 2. The light from the ring light source 20 evenly illuminates the surface of the skeleton to avoid measurement errors caused by reflection. The ring light source 20 is an LED light source, and the detection camera 19 is a CCD camera to achieve accurate measurement of hole size and position.

[0029] The workbench 1 is provided with an installation cabinet 7 at its lower part. The installation cabinet 7 contains a number of defective product boxes 12. The lower end of the suction pipe 11 passes through the workbench 1 and extends above the corresponding defective product box 12.

[0030] The bottom of the electric conveyor belt 2 is connected to the material blocking cylinder 17 via a cylinder bracket 24, which is L-shaped.

[0031] A connecting bracket 30 is installed on the material dispensing slider 22. The material stop rod 25 and the material pressing rod 28 are respectively fixed at both ends of the connecting bracket 30. The material pressing rod 28 is a circular top rod. A spring 29 is sleeved on the material pressing rod 28. One end of the material pressing rod 28 passes through the connecting bracket 30 and is screwed with a limit bolt.

[0032] The material distribution rod 26 is provided with a downward baffle 31 at one end, and the electric conveyor belt 2 is provided with an opening 27 for the baffle 31 to pass through.

[0033] An infrared sensor 32 is installed on one side of each stop bar 25 on the electric conveyor belt 2. The infrared sensor 32 is used to detect whether the relay frame 4 has reached the stop bar 25.

[0034] The relay frame 4 being transported on the electric conveyor belt 2 is placed upside down, with its original upper surface facing forward and its original rear surface facing backward. For example... Figure 1 and Figure 2 As shown, this utility model has two inspection stations. The inspection station on the left is used to inspect whether the through hole 34 of the skeleton is qualified, and the inspection station on the right is used to inspect whether the pin hole 35 and the coil slot hole 36 are qualified. Each inspection station includes a material distribution device 10, a hole position detection device 8, and a material picking device 9.

[0035] like Figures 4-5 As shown, when the material distribution device 10 is not working, the baffle 31 at one end of the material distribution rod 26 is located on the electric conveyor belt 3, blocking the relay frames 4 arranged in a row; when the material distribution device 10 is working, the material distribution cylinder 23 controls the material distribution slider 22 to slide towards the electric conveyor belt 3, the baffle 31 at one end of the material distribution rod 26 is inserted into the opening 27, one end of the baffle rod 25 is inserted into the electric conveyor belt 3, and at the same time the pressing rod 28 pushes against the second relay frame 4 in the row, and the first relay frame 4 in the row, due to the absence of the baffle 31, moves smoothly. The relay frame 4 is transported to the baffle bar 25. At this time, the hole position detection device 8 can detect the relay frame 4. After the detection is completed, the material distribution cylinder 23 controls the material distribution slider 22 to reset. The baffle 31 at one end of the material distribution bar 26 returns to the electric conveyor belt 3. The pressure bar 28 releases the second relay frame 4. This second relay frame 4 is transported to the baffle 31 and becomes the first relay frame 4. The baffle bar 25 retracts, so that the detected relay frame 4 is transported to the material picking device 9.

[0036] The material handling device 9 includes a suction pipe 11, a gate cylinder 14, and a gate 15. The rear end of the electric conveyor belt 2, located to the right of each hole detection device 8, is equipped with a discharge port 13 and a gate 15 installed inside the discharge port 13. The discharge port 13 is equipped with a suction pipe 11 and an air nozzle. The bottom of the electric conveyor belt 2 is equipped with a gate cylinder 14 that drives the gate 15 to move up and down. The front end of the electric conveyor belt 2, located in front of the gate 15, is equipped with a blocking cylinder 17. The blocking cylinder 17... The stop rod is connected to a second baffle rod 16, one end of which is horizontally inserted into the electric conveyor belt 2 from front to back. The relay frame 4 after inspection is transported to the second baffle rod 16. When the inspection is qualified, the second baffle rod 16 retracts, so that the relay frame 4 is sent to the next inspection. Otherwise, if the inspection is unqualified, the gate cylinder 14 is activated. The gate cylinder 14 controls the gate 15 to move downward to expose the discharge port 13. The air nozzle blows air to blow the unqualified relay frame 4 into the suction pipe 11, and finally it falls into the corresponding unqualified product box 12.

[0037] An infrared sensor 33 is installed on one side of each stop bar 16 on the electric conveyor belt 2. The infrared sensor 33 is used to detect whether the relay frame 4 has reached the stop bar 16.

[0038] The number of the material receiving device 9, including the baffle rod 16, the baffle cylinder 17, the suction pipe 11, and the air nozzle, can be increased or decreased according to the number of defects detected in the product.

[0039] The specific working process of this utility model is as follows: The relay frame 4 is placed in the vibratory plate 3. After the vibratory plate 3 arranges and sorts the relay frame 4, it is transported in an orderly manner to the inlet of the electric conveyor belt 3. The electric conveyor belt 3 transports the relay frame 4 to the left inspection station. The left inspection station is used to check whether the through hole 34 of the frame is qualified. After the relay frame 4 is qualified, it is transported to the right inspection station. The unqualified relay frame 4 is collected by the picking device 9. The right inspection station is used to check whether the pin hole 35 and the coil slot hole 36 are qualified. After the inspection is qualified, the relay frame 4 falls into the collection box 6. The unqualified relay frame 4 is collected by the picking device 9.

[0040] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.
