This makes it possible to blow out the devices 30 on the first narrow passage section 152 that do not conform to the side-up posture, thereby ensuring that the devices 30 entering the second twisted section 153 are the devices 30 in the side-up posture.

In an embodiment of the present application, referring to fig. 2, fig. 3, and fig. 6, a second detector 24 is installed on the annular wall 12, the second detector 24 is located at a position corresponding to the second slot 1540, the second detector 24 is used for detecting the posture of the device 30, a second air blowing hole 1202 is formed in the annular wall 12, the second air blowing hole 1202 is located at a side of the second slot 1540 away from the tray body 11, and the second air blowing hole 1202 is used for blowing out the device 30 that does not conform to the inverted posture. This blows out the devices 30 on the second narrow channel section 154 that do not conform to the inverted posture, ensuring that the posture of the devices 30 output from the vibratory tray remains inverted.

In this way, the device 30 not in the side-up posture on the first narrow passage section 152 can be blown out, and the posture of the device 30 entering the second twisted section 153 can be maintained in the side-up posture.

Alternatively, referring to fig. 2 to 4, the first blowing hole 1201 is located at an end of the first slot 1520 far from the first twisted section 151, and the first blowing pin 21 is located at an end of the first slot 1520 near the first twisted section 151, so that the stacked devices 30 are removed and detected, thereby preventing the stacked devices 30 from affecting the detection of the first detector 23.

In one embodiment of the present application, referring to fig. 2 to 4, the sorting air plate 25 is mounted on the annular wall 12, the sorting air plate 25 is located on a side of the first slot 1520 away from the tray body 11, the sorting air plate 25 is used for blowing air towards the first slot 1520, and on the first narrow passage section 152, when the width direction a2 of the device 30 is perpendicular to the upper surface of the first narrow passage section 152, the sorting air plate 25 blows the device 30 off, so that the device 30 falls onto the tray body 11. After passing through the first twist section 151, the leads 32 of the device 30 face in a direction away from the axis of the tray 11, but the device 30 mainly has two postures, one in which the length direction a1 of the device 30 is substantially parallel to the axis direction of the tray 11, i.e., a side-standing posture, and the other in which the width direction a2 of the device 30 is substantially parallel to the axis direction of the tray 11; because the length of the device 30 is greater than the width of the device 30, the gravity center of the device 30 with the length direction a1 being substantially parallel to the axial direction of the tray body 11 is higher, when the sorting air plate 25 blows air into the first slot 1520, negative pressure is formed on one side of the device 30 close to the axial direction of the tray body 11, so that the device 30 with the gravity center close to the first slot 1520 (i.e., the device 30 with the width direction a2 being substantially parallel to the vertical direction) is turned over and falls off, and thus the device 30 with the width direction a2 being perpendicular to the upper surface of the first narrow channel section 152 can be removed, so that the device 30 output by the first narrow channel section 152 can be kept in a side-standing posture, and the device 30 with the width direction a2 being parallel to the traveling direction is controlled to be conveyed backwards. The air outlet of the air separation plate 25 is disposed along the length direction of the first slot 1520, and the length thereof may be approximately equal to the width of one device 30.

Alternatively, referring to fig. 2 to 4, the sorting plate 25 is located between the first blowing pin 21 and the first blowing hole 1201, when the device 30 passes through the first slot 1520, the first blowing pin 21 blows off the stacked device 30 first, the sorting plate 25 blows off the device 30 in the non-side-standing posture, and the first detector 23 detects the device finally, and blows off the device 30 not in the side-standing posture by using the first blowing hole 1201, thereby ensuring the output of the device 30 in the side-standing posture.

In an embodiment of the present application, referring to fig. 2, fig. 3 and fig. 5, the annular wall 12 is mounted with a pushing block 26, the pushing block 26 is located at the feeding end of the second twisting section 153, the pushing block 26 has a pushing surface 261, the pushing surface 261 is located at a side of the pushing block 26 close to the axis of the tray body 11, the pushing surface 261 is used for stopping the device 30, when the device 30 in the side-standing posture passes through the pushing block 26, the pushing surface 261 stops the device 30, so that the device 30 is tilted toward the side of the second twisting section 153 close to the axis of the tray body 11, thereby the device 30 in the side-standing posture is turned over, and the device 30 is prevented from being attached to the annular wall 12 due to the gravity center of the device 30 being close to the annular wall 12.

Alternatively, referring to fig. 2, 5 and 7, the cross-sectional line of the pushing surface 261 on the axial surface of the disc 11 is inclined from the side of the pusher block 26 close to the disc 11 to the side of the pusher block 26 away from the disc 11 in a direction toward the axis of the disc 11, and in the conveying direction of the device 30: the inclination angle of the section line of the pushing surface 261 on the axial surface of the disc body 11 gradually increases. That is, the difference between the vertical distance from the lower end of the pushing face 261 to the axis of the tray body 11 and the vertical distance from the upper end of the pushing face 261 to the axis of the tray body 11 gradually increases, and the magnitude of the increase in the difference gradually increases in the conveying direction of the devices 30. This facilitates the device 30 to be pushed down to the side of the second torsion section 153 near the axis of the disc 11 when the device 30 enters the second torsion section 153.

In an embodiment of the present application, referring to fig. 2 to 3, the number of the first twisted sections 151 is two, the number of the first narrow sections 152 is two, and the two first twisted sections 151 and the two first narrow sections 152 are alternately arranged along the transmission path of the device 30; the upstream first twisted section 151 is connected to the curved track 14, and the downstream first narrow section 152 is connected to the second twisted section 153. In this way, the two first twisted sections 151 and the two first lane sections 152 can ensure that the device 30 assumes a side-up position when entering the second twisted section 153. As some of the devices 30 pass through the first narrow lane section 152, the devices 30, if in an upright position, may be twisted into a side-on position as they pass through the second first twisted section 151.

In one embodiment, the top of the first torsion section 151 has a first torsion surface and a second torsion surface, the second torsion surface is located on one side of the first torsion surface close to the annular wall 12, and the width direction of the first torsion surface is substantially perpendicular to the width direction of the second torsion surface; the section line of the second torsion surface on the axial surface of the disc body 11 is inclined from the side close to the axis of the disc body 11 toward the side away from the axis of the disc body 11 in the direction away from the disc body 11, along the transport direction of the device 30: the angle of inclination of the second torsion surface gradually increases, that is, the end of the second torsion surface away from the axis of the tray body 11 gradually inclines upward, and the angle of inclination thereof gradually increases in the transport direction of the device 30. Thus, the device 30 is close to the second torsion surface, and the included angle between the device 30 and the vertical plane is gradually reduced along with the transmission of the device 30, so that the device 30 is gradually turned over.

In one embodiment, at the feed end of the first twisting stage 151: the included angle between the width direction of the second torsion surface and the horizontal direction is 30-55 degrees; at the discharge end of the first twisting stage 151: the included angle between the width direction of the second torsion surface and the horizontal direction is 70-90 degrees. As such, when the device 30 enters the first torsion section 151 in an upright posture, the device 30 slides to the second torsion surface due to its low center of gravity; when the device 30 enters the first torsion portion 151 in a side-up posture, the device is likely to turn over due to its high center of gravity. This allows the device 30 to be turned over to a side-up position for output when it enters the first twisting section 151 in a side-up position; when the device 30 is input to the first twisted portion 151 in the side-up posture, it is turned over to abut against the second twisted surface in a direction away from the axis of the disk 11 and then turned over in a direction close to the axis of the disk 11, so that the side-up posture can be maintained at the time of output. Optionally, at the feeding end of the first twisting stage 151: the included angle between the width direction of the second torsion surface and the horizontal direction can be 35 degrees, 40 degrees, 45 degrees, 50 degrees or the like. Optionally, at the discharge end of the first twisting stage 151: the angle between the width direction of the second torsion surface and the horizontal direction may be 75 °, 80 °, 85 °, or the like.

Optionally, the angle of inclination of the feeding end of the second twisting surface of the downstream first twisting stage 151 is greater than the angle of inclination of the feeding end of the second twisting surface of the upstream first twisting stage 151. This facilitates the device 30, which enters the second first torsion section 151 in the side-up state, to be turned against the second torsion surface.

In one embodiment of the present application, referring to fig. 2, 3 and 6, the section line of the upper surface of the curved track 14 on the axial surface of the disk 11 is an arc with a convex middle portion toward the disk 11. That is, on the axial surface of the disk body 11, the section line of the curved surface rail 14 is an arc line whose central portion is convex toward the disk body 11. This makes it possible to stabilize the device 30 when the center of gravity is low, and to gradually adjust the device 30 having a high center of gravity (the device 30 in the side-standing posture and the inverted posture) to the upright state while being easily turned on the side during movement. Among the four pins 32 of the device 30, when the distance between two adjacent pins 32 along the length direction of the device 30 is greater than the distance between two adjacent pins 32 along the width direction of the device 30, the device 30 in the upright posture is more stable, which is beneficial to controlling the device 30 to output in the upright posture.

Alternatively, the number of turns of the curved track 14 may range from 0.5 to 3. That is, the corresponding central angle of the curved track 14 on the tray 11 is in the range of 0.5-3, which allows sufficient time for the device 30 to adjust to the upright position. The number of turns of the curved track 14 may be 0.75, 1, 1.5, 2, 2.5, etc.

Alternatively, the width direction of the upper surface of the output end of the curved rail 14 is inclined toward the direction away from the tray 11 from the side of the curved rail 14 close to the axis of the tray 11 to the side of the curved rail 14 away from the axis of the tray 11, in the transport direction of the device 30: the inclination angle of the upper surface of the output end of the curved track 14 in the width direction gradually increases. This enables the inclination angle of the upper surface of the output end of the curved track 14 to be substantially the same as the inclination angle of the second twisting surface of the input end of the first twisting section 151, which facilitates the device 30 to maintain its posture into the first twisting section 151.

In an embodiment of the present application, referring to fig. 2 and 3, the vibration plate further includes an input rail 13, the input rail 13 is used for guiding the devices 30 to sequentially input into the curved rail 14, the input rail 13 is disposed on one side of the annular wall 12 close to the axis of the plate body 11, the feeding end of the input rail 13 is connected to the plate body 11, and the discharging end of the input rail 13 is connected to the feeding end of the curved rail 14. This can gradually spread the devices 30 apart, reducing the stacking and parallelization of the devices 30, so that the devices are arranged one by one and input to the curved surface rails 14, and avoiding affecting the adjustment of the postures of the devices 30 on the curved surface rails 14.

Optionally, the discharge end of the input rail 13 is provided with a third opening 130, and the third opening 130 is located on one side of the input rail 13 near the axis of the disk 11. This avoids parallelism of the output of the devices 30 from the input tracks 13.

Optionally, the device 30 is inclined on the input track 13 at an angle less than or equal to 20 °, i.e., the tangent to the input track 13 is at an angle less than or equal to 20 ° to the radial plane of the disk 11. In this manner, the input of the device 30 to the curved track 14 is facilitated.

The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
