DETAILED DESCRIPTION

[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0028] Reference Figure 1 As shown, a precision micro-machined parts feeding mechanism described in the utility model includes: a vibrating feeder 1, a material guide trough 2 is provided at the discharge channel of the vibrating feeder 1; a straight vibrator 3 is installed at the bottom of the material guide trough 2 through a support 4; a rotating disk 5 is arranged at the outlet of the material guide trough 2 for receiving the workpieces 100 conveyed in the material guide trough 2 and sending them one by one to the next process; a magnetic suction fixture 6, including a plurality of magnetic suction fixtures 6, which are arranged on the rotating disk 5 at equal intervals in the annular direction and are used to limit and fix the workpieces 100 conveyed from the material guide trough 2.

[0029] like Figure 4As shown, the magnetic fixture 6 includes a magnetic fixing part 61 and a contour positioning part 62, the magnetic fixing part 61 is provided with a fitting reference surface 611, the magnetic fixing part 61 is provided with a groove 612 near the fitting reference surface 611, and a micro magnet is arranged in the groove 612. The contour positioning part 62 is provided with a light-transmitting hole 621. It should be noted that the contour positioning part 62 needs to be arranged according to the shape characteristics of the workpiece 100. The micro magnet plays the role of assisting the product to fit the reference surface 611, and the contour positioning part 62 supports and positions the head of the workpiece 100, so that there is no need to manually clamp the fixture for detection. At the same time, due to the light-transmitting hole 621 on the contour positioning part 62, when the workpiece 100 is buckled on the contour positioning part 62, it is convenient for the visual inspection mechanism to measure the aperture of the circular hole on the workpiece 100.

[0030] like Figure 5 As shown, after the workpiece 100 is fixed by the magnetic fixture 6, the side of the workpiece 100 is fixed to the fitting reference surface 611 by magnetic attraction, and the head of the workpiece 100 is positioned on the profiling positioning part 62, so as to effectively support the head of the workpiece 100. In this embodiment, the profiling positioning part 62 adopts a ball head profiling and fitting product appearance design, which effectively supports the product for visual imaging inspection.

[0031] like Figure 2 and 3 As shown, the guide trough 2 includes a trough body, and a sliding guide groove 21 is provided in the trough body. The sliding guide groove 21 includes a first sliding guide groove 211 and a second sliding guide groove 222, and the second sliding guide groove 212 is embedded in the middle of the first sliding guide groove 212. The first sliding guide groove 211 and the second sliding guide groove 222 can realize dual guidance of the workpiece 100, ensuring that the workpiece 100 conveyed in the guide trough 2 can be accurately conveyed to the magnetic fixture 6 for position fixing, avoiding the situation where the workpiece 100 slides out of the guide trough 2 and cannot be aligned with the magnetic fixture 6 due to deflection.

[0032] The trough body described in this embodiment includes a horizontal trough body 200 and an inclined trough body 201, and the horizontal trough body 200 and the inclined trough body 201 are integrally formed. The horizontal trough body 200 and the inclined trough body 201 described in this embodiment form an angle of 120°. The horizontal trough body 200 transfers the workpiece 100 in the vibrating feeder 1 to the inclined trough body 201 and arranges them in a row. When the vibrating feeder 1 discontinuously outputs the workpiece 100, the workpiece 100 will wait on the horizontal trough body 200 of the guide trough 2. When the straight vibrator 3 is working, the workpiece 100 passes through the horizontal trough body 200 to transfer the workpiece to the inclined trough body 201, so as to realize the continuous transportation of the workpiece 100. Due to the angle design of the inclined trough body 201, the workpiece 100 moves slowly in the inclined trough body 201, and finally falls from the inclined trough body 201 to the magnetic fixture 6 for adsorption and fixation.

[0033] In addition, mounting plates 203 are provided on both sides of the horizontal tank body 200, and mounting holes 204 are provided on the mounting plates 203. When the horizontal tank body 200 is installed, bolts are inserted into the mounting holes 204 on the mounting plates 203 to fix the horizontal tank body 200 and the vertical vibrator 3 together.

[0034] Specifically, the end of the inclined trough body 201 is provided with an inclined contact surface 202 for contacting the plane of the rotating disk 5. A chamfer is provided at the connection between the end of the inclined trough body 201 and the inclined contact surface 202. The design of the chamfer makes it difficult to cause scratches on the workpiece 100 when loading the workpiece.

[0035] Furthermore, an elastic limiting rod 22 is provided at the end of the inclined trough 201 at the discharge port of the first sliding guide groove 211. When the rotating disk 5 drives the magnetic fixture 6 to rotate to the bottom of the inclined trough 201, the elastic limiting rod 22 presses the workpiece 100 down onto the magnetic fixture 6 for adsorption and fixation, and finally, the workpiece 100 rotates with the rotating disk 5 to the subsequent station for detection and sorting operations.

[0036] By utilizing the magnetic suction fixture 6 of the utility model, in cooperation with the vibrating feeder 1 and the guide trough 2, stable feeding of the workpiece 100 can be achieved, and automated detection can be realized to replace manual detection one by one using a clamping fixture, thereby realizing full automatic feeding in a shorter time, avoiding the problem of low efficiency of manual feeding, further enhancing customer satisfaction, and also greatly saving labor costs and management costs, and having the advantages of good product clamping stability and high detection accuracy.

[0037] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
