Description

Technical Field

[0001] This utility model relates to the field of directional feeding technology, and in particular to a contour directional feeding mechanism for products with elongated holes. Background Technology

[0002] Inserts with elongated holes inside need to be fed into the injection mold in a specific direction.

[0003] The current method for feeding products with such elongated holes is to visually identify the angle between the inner hole's symmetry line and the horizontal direction, and then use a stepper motor or servo motor to rotate the product at different angles to the horizontal direction. However, this method requires expensive camera, light source, motor, and corresponding software. Summary of the Invention

[0004] In view of this, the purpose of this utility model is to propose a contour-guided feeding mechanism for products with elongated holes, so as to solve the problem of high cost.

[0005] To achieve the above objectives, this utility model provides a contour-guided feeding mechanism for products with oblong holes, including a mounting plate. A feeding platform is provided on the mounting plate, and a pneumatic vibrator connected to the mounting plate is provided on one side of the feeding platform. A material groove for placing the product body with the oblong hole is opened on the upper surface of the feeding platform. A through hole is opened on the feeding platform, and a contour-guided guide rod is provided in the through hole. A contour head is provided at the head of the contour-guided guide rod. The lower end cross section of the contour head is configured to match the shape of the oblong hole of the product body. A telescopic cylinder connected to the mounting plate is connected to the lower end of the contour-guided guide rod, and the telescopic cylinder is used to control the up and down movement of the contour-guided guide rod.

[0006] Optionally, the upper cross section of the contouring head is a circle with the short side of the elongated hole of the product body as its diameter.

[0007] Optionally, the shape of the profiling head gradually transitions from a circle with the short side of the elongated hole of the product body as its diameter to the elongated hole shape of the product body from top to bottom.

[0008] Optionally, the through hole is a stepped circular hole, which includes a small circular hole and a large circular hole located below the small circular hole.

[0009] Optionally, a central positioning ring connected to the mounting plate is provided inside the large circular hole, and the central axis of the central positioning ring is arranged to coincide with the axis of the large circular hole.

[0010] Optionally, the contour guide rod has a strip groove, the length of which is vertical, and a pin that passes through the strip groove is connected to the inner wall of the through hole.

[0011] Optionally, the pneumatic vibrator is mounted on the lower end face of the mounting plate.

[0012] Optionally, an upper proximity switch connected to the mounting plate is provided diagonally above the through hole, and a lower proximity switch is provided below the telescopic cylinder. The lower proximity switch is connected to the mounting plate through a connecting bracket, and the upper proximity switch is connected to the pneumatic vibrator. Both the upper and lower proximity switches are connected to the telescopic cylinder, which is an electric cylinder.

[0013] Optionally, the connecting frame includes an upright plate and a flat plate, the lower proximity switch is disposed on the flat plate, the flat plate is connected to the mounting plate through the upright plate, and diagonal reinforcing ribs are provided between the upright plate and the flat plate, and between the upright plate and the mounting plate.

[0014] The beneficial effects of this utility model are as follows: This utility model provides a contour-guided feeding mechanism for products with oblong holes. When the product body is fed directly above the through hole in the material trough, the telescopic cylinder below the through hole is activated. The telescopic end of the telescopic cylinder extends, causing the contour-guided head of the contour-guided rod to pass through the oblong hole on the product body and push the product body upward. At the same time, the pneumatic vibrator starts to vibrate. Under the action of vibration, gravity, and the contour-guided rod, the product body will transition to the correct direction and be pushed higher than other product bodies, making it easier for other gripping mechanisms to pick it up and send it into the mold. Through the combination of the contour-guided rod, the pneumatic vibration of the pneumatic vibrator, the lifting drive of the telescopic cylinder, and gravity assistance, the product body with an oblong hole in a random direction is automatically corrected to the required direction of the oblong hole on the product body, completely eliminating the need for an expensive visual recognition system and reducing costs.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0026] like Figures 1 to 7As shown, a contour-guided feeding mechanism for an elongated hole product includes a mounting plate 1, a feeding platform 11 on the mounting plate 1, a pneumatic vibrator 2 connected to the mounting plate 1 on one side of the feeding platform 11, a material groove 15 for placing the product body 17 with the elongated hole on the upper surface of the feeding platform 11, a through hole 12 on the feeding platform 11, a contour-guided guide rod 9 inside the through hole 12, a contour head at the head of the contour-guided guide rod 9, the lower end cross section of the contour head matching the shape of the elongated hole of the product body 17, and a telescopic cylinder 7 connected to the mounting plate 1 at the lower end of the contour-guided guide rod 9, the telescopic cylinder 7 being used to control the up and down movement of the contour-guided guide rod 9.

[0027] When the product body 17 is delivered to the top of the through hole 12 in the material trough 15, the telescopic cylinder 7 below the through hole 12 is activated. The telescopic end of the telescopic cylinder 7 extends, driving the contouring head of the contouring guide rod 9 to pass into the elongated hole on the product body 17. The product body 17 is strung on the contouring guide rod 9. The telescopic cylinder 7 continues to extend, pushing the product body 17 upward. At the same time, the pneumatic vibrator 2 starts to vibrate. Under the action of vibration, gravity, and the contouring guide rod 9, the product body 17 will transition to the correct direction and be pushed higher than other product bodies 17, making it easier for other gripping mechanisms to grab it and send it into the mold.

[0028] By using a contour-guided guide rod 9 and the vibration of a pneumatic vibrator 2 to guide the product body 17 within a certain stroke, gravity is used to gradually correct the product body 17 to the correct direction. Through the combination of the contour-guided guide rod 9, the pneumatic vibration of the pneumatic vibrator 2, the lifting drive of the telescopic cylinder 7, and gravity assistance, the product body 17 with a random oblong hole is automatically corrected to the required direction of the oblong hole of the product body 17. This completely eliminates the need for an expensive visual recognition system and reduces costs.

[0029] The telescopic cylinder 7 is mounted on the mounting plate 1 via the column 6.

[0030] The upper end of the contouring head is provided with a protrusion, which can be a cone or a hemisphere, to facilitate the contouring head to pass through the elongated hole of the product body 17.

[0031] The upper cross section of the contouring head is a circle with the short side of the elongated hole of the product body 17 as its diameter.

[0032] The shape of the profiling head gradually transitions from a circle with the short side of the elongated hole of the product body 17 as its diameter to the elongated hole shape of the product body 17 from top to bottom.

[0033] The through hole 12 is a stepped circular hole, which includes a small circular hole 14 and a large circular hole 13 located below the small circular hole 14.

[0034] A central positioning ring 16 connected to the mounting plate 1 is provided inside the large circular hole 13. The central axis of the central positioning ring 16 coincides with the axis of the large circular hole 13, and the central positioning ring 16 is easy to position.

[0035] The contour guide rod 9 has a strip groove 10, which is vertically oriented along its length. A pin 8 is connected to the inner wall of the through hole 12, which passes through the strip groove 10. The strip groove 10 and the pin 8 cooperate to guide the contour guide rod 9 within a certain stroke, so that the contour guide rod 9 moves along a fixed direction, preventing the contour guide rod 9 from rotating and deviating.

[0036] The pneumatic vibrator 2 is installed on the lower end face of the mounting plate 1. The pneumatic vibrator 2 provides high-frequency micro-vibration and uses gravity to gradually correct the product to the correct direction, which facilitates the guidance setting of the product body 17.

[0037] An upper proximity switch 4, connected to the mounting plate 1, is provided diagonally above the through hole 12. A lower proximity switch 5 is provided below the telescopic cylinder 7. The lower proximity switch 5 is connected to the mounting plate 1 via a connecting bracket 3. The upper proximity switch 4 is connected to the pneumatic vibrator 2. Both the upper proximity switch 4 and the lower proximity switch 5 are connected to the telescopic cylinder 7, which is an electric cylinder. When the product body 17 is sent to the top of the contour guide rod 9 in the material trough 15, the upper proximity switch 4 is turned on. The telescopic end of the electric cylinder extends, driving the contour guide rod 9 to push the product body 17 upward. At the same time, the pneumatic vibrator 2 starts to vibrate. The contour head surface of the contour guide rod 9 is polished to a mirror finish. Under the action of vibration, gravity, and the contour guide rod 9, the product body 17 will transition to the correct direction and be pushed higher than other product bodies 17. It will then be picked up by other gripping mechanisms and sent into the mold.

[0038] The electric cylinder is connected to the contour guide rod 9 via a coupling, providing precise lifting and lowering motion.

[0039] The connecting frame 3 includes an upright plate and a flat plate. The lower proximity switch 5 is disposed on the flat plate. The flat plate is connected to the mounting plate 1 through the upright plate. Diagonal reinforcing ribs are provided between the upright plate and the flat plate, and between the upright plate and the mounting plate 1, to improve the strength of the connecting frame 3.

[0040] The material trough 15 is equipped with a conveyor belt for transporting the product body 17, which facilitates the transfer of the product body 17 within the material trough 15.
