[0031] The present invention provides a steel ball feeding device. To make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0032] See also Figures 1 to 9 The present invention provides a steel ball feeding device. The accompanying drawings are only used to illustrate the structural principles and are not to scale with the actual product. The accompanying drawings only depict structures related to the invention of this application and do not specifically depict some conventional structures. The terms "first" and "second" described herein are merely different names for similar structures to facilitate explanation and are not intended to limit this application.

[0033] The steel ball feeding device comprises a frame 11, a worktable 12, and a hopper 20 connected to a feed pipe. The worktable is equipped with a pusher block 31 and a pusher block drive cylinder 39 for linear reciprocating motion. The pusher block is equipped with a counting sensor 91. The worktable is equipped with a detection mechanism for detecting the diameter of the steel balls. A sorting mechanism is located downstream of the pusher block to separate good and defective steel balls. The detection mechanism and sorting mechanism will be described in detail below.

[0034] The top of the feed tube is connected to the bottom of the hopper. In practice, the hopper is filled with many steel balls (not shown), and some of them may become lodged in the discharge port at the bottom of the hopper, preventing them from properly falling into the feed tube. To address this issue, the feed tube can be configured as follows: the feed tube comprises an inner tube 21 and an outer tube 22. The steel ball feeding device also includes an outer tube drive cylinder 29 for driving the outer tube up and down. In other words, if a steel ball becomes stuck, simply activate the outer tube drive cylinder to move the outer tube upward and then reset it. This agitates the steel balls at the bottom of the hopper, allowing them to smoothly enter the inner tube.

[0035] like Figure 5 and Figure 6 As shown, the pusher block 31 is further provided with a vertical through-hole 310 and a first horizontal through-hole 311, which is in communication with the vertical through-hole. The counting sensor 91 is a photoelectric sensor, the probe of which is coaxially arranged with the first horizontal through-hole. In actual use, when a steel ball falls into the vertical through-hole in the pusher block, the photoelectric sensor can count the steel balls in the pusher block.

[0036] Please continue reading Figure 5 and Figure 6 Furthermore, the push block is provided with a second horizontal through hole 312, which is connected to the vertical through hole; the detection mechanism includes a displacement sensor 5, a detection rod 41, and a detection rod driving cylinder 49; the probe head 51 of the displacement sensor is connected to the detection rod, and the detection rod is inserted into the second horizontal through hole. There can be a variety of connection methods between the detection head and the detection rod. The accompanying drawings propose a simple connection method, namely: the probe head 51 is connected to the detection rod 41 through the connecting block 42, and the piston rod of the detection rod driving cylinder 49 is connected to the connecting hole. During detection, the detection rod driving cylinder drives the detection rod to extend forward until it hits the steel ball. During this process, the displacement sensor detects the diameter of the steel ball according to the moving position of the probe head.

[0037] By the attached Figure 3 It can also be observed that a guide block 32 is provided on the outside of the pusher block. By providing the guide block, when the pusher block drives the cylinder to drive the pusher block to move back and forth, it plays a guiding and limiting role.

[0038] Furthermore, a discharge hole 120 (such as Figure 5 As shown in the figure). Figures 7 to 9As shown, the material separation mechanism includes a chute 61, a slider 62 disposed in the chute, and a slider-driving cylinder 69 for driving the slider to reciprocate. The slider is provided with a receiving hole 621 for good products and a receiving hole 622 for defective products, and the chute is provided with a discharge hole 611 for good products and a discharge hole 612 for defective products. This arrangement facilitates the sorting of good and defective steel balls. It can also be observed from the accompanying drawings that a cover plate 63 is provided on the top of the slider, which is also provided with a through hole (not shown in the figure) that is aligned with the discharge hole on the workbench. It should be noted that the cover plate 63 is not a necessary structure; it is provided to facilitate both limiting the slider in the vertical direction and installing the slider-driving cylinder.

[0039] like Figure 8 As shown, a good product discharge pipe 71 is provided at the good product discharge port, and a defective product discharge pipe 72 is provided at the defective product discharge hole. Two second photoelectric sensors 92 are positioned opposite the good product discharge pipes. The purpose of the second photoelectric sensor is to perform a secondary count of the good steel balls, further improving the counting accuracy. Since the steel balls fall at a high speed, the two photoelectric sensors can ensure detection accuracy.

[0040] In actual application, a good product collection box 81 (such as Figure 4 As shown in the figure), a defective product collection box is provided below the defective product discharge pipe (not shown in the figure).

[0041] For easier understanding, the working principle is further explained below.

[0042] During actual operation, when it is detected that the diameter of the steel ball is qualified, the slider drives the cylinder to move so that the good product discharge hole is aligned with the discharge hole on the workbench, and then the push block drives the cylinder to push the push block forward, and the steel ball falls from the discharge hole of the workbench to the good product receiving hole of the slider (at this time, the good product receiving hole is located between the good product discharge hole and the defective product discharge hole of the chute), and the slider drives the cylinder to move so that the good product receiving hole is aligned with the good product discharge hole, and the steel ball enters the good product discharge pipe and falls into the good product collection box. Similarly, when it is detected that the diameter of the steel ball is unqualified, the slider drives the cylinder to move so that the defective product receiving hole is aligned with the discharge hole on the workbench (at this time, the defective product receiving hole is located between the good product discharge hole and the defective product discharge hole of the slide), and then the push block drives the cylinder to push the push block forward, and the steel ball falls from the discharge hole of the workbench to the defective product receiving hole of the slider. The slider drives the cylinder to move so that the defective product discharge hole is aligned with the defective product discharge hole, and the steel ball enters the defective product discharge pipe and falls into the defective product collection box.

[0043] In practice, the steel ball feeding device includes a controller (not shown), a control panel 18 (preferably a touch screen), and operating buttons 19. The user can enter the desired number of steel balls and their diameter on the control panel. Once the steel ball feeding device is operational, it can discharge the desired number of good steel balls into a good-quality box.

[0044] It should be noted that this application seeks protection for the structure of the steel ball feeding device itself, rather than for a new computer program. Therefore, this article will no longer elaborate on the content related to the control of this device.

[0045] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and the utility model concept of the present invention, and all these changes or substitutions should fall within the scope of protection of the present invention.
