Abstract
Description
Technical Field
[0001] This utility model relates to the field of positioning and feeding technology, and in particular to a loading machine. Background Technology
[0002] The substrate of inductor components is typically formed by cold pressing of powder. After forming, it is transferred to a tray via a stacking machine for further processing. Cold-pressed components often have powder residue, and those not further processed after forming have low hardness, making them prone to breakage and damage during transfer. Furthermore, to ensure accurate placement on the tray, the components require further positioning after being transferred from the cold pressing machine. Traditional abutment-based positioning methods can easily cause compression, leading to component breakage and quality issues. Therefore, ensuring the stability of the inductor component transfer process after cold pressing and before further hardening is a problem that those skilled in the art need to consider.

[0031] The present invention will be further described in detail below with reference to specific embodiments:
[0032] like Figures 1-5 As shown, this utility model is applied to the transfer and collection of inductor components formed by cold pressing of powder. A robotic arm drives a first clamping device to extend into the mold of the cold pressing equipment 4, simultaneously clamping multiple formed inductor components and transferring them to a pitch-changing device for positioning. The pitch-changing device drives a material block to adjust the spacing between the multiple inductor components. Then, a second clamping device simultaneously clamps all the inductor components on the material block and transfers them to a tray on the unloading plate. An empty tray is moved to the side of the unloading plate by a first conveying device; then, pushed by a pusher, it moves to the unloading plate. After the unloading plate is filled with inductor components, it moves to the second conveying device by the pusher, and finally, the second conveying device transfers them to a second material bin for collection. Specifically:
[0033] A loading machine includes a loading mechanism 1, a positioning mechanism 2, and a unloading mechanism 3.
[0034] The feeding mechanism 1 includes a robotic arm 11 and a first gripping device 12 connected to the robotic arm 11. The first gripping device 12 is provided with a plurality of first grippers 13, which are evenly arranged. Pressure sensors are provided on the first grippers 13. A brush assembly 14 is also connected to the robotic arm 11. The brush assembly 14 is located on the side opposite to the first gripping device 12 and includes at least two brushes 141 facing upward and downward, respectively.
[0035] In this embodiment, six first grippers 13 are arranged side by side, corresponding to the six inductor elements to be cold-pressed each time. The first grippers 13 simultaneously grip all six inductor elements, and while gripping, they precisely maintain a preset gripping force based on feedback data from pressure sensors. This ensures effective pickup while preventing excessive gripping force that could damage the inductor elements. Depending on the actual cold-pressing process, after each or several inductor element removals, the robotic arm 11 drives the brush assembly 14 to brush the mold of the cold-pressing equipment. The upper brush brushes the upper mold and punch, while the lower brush brushes the lower mold, to prevent residual powder from affecting the molding of the inductor elements.
[0036] The positioning mechanism 2 includes a pitch-changing device 21 and a material block 22 connected to the pitch-changing device 21. The material block 22 is provided with a material loading groove 23. The side wall of the material loading groove 23 is provided with a plurality of suction holes 231, and at least one suction hole 231 is provided simultaneously in two adjacent side walls. One side of the material loading groove 23 extends toward the edge of the material block 22 to form a first opening 232; a through elongated hole 233 is provided at the bottom of the end away from the first opening 232; the suction hole 231 is located above the elongated hole 233.
[0037] The positioning mechanism 2 also includes a dust suction pipe 24 and a plurality of air blowing needles 25, the air blowing needles 25 having an air outlet direction facing the first opening 232; the opening of the dust suction pipe 24 is located on the side of the material loading trough 23 away from the air blowing needles 25, and its opening direction faces the air outlet direction of the air blowing needles 25.
[0038] In this embodiment, the orientation of the inductor components gripped and placed in the material tray 23 by the feeding mechanism 1 may be slightly offset. Furthermore, the spacing between two adjacent inductor components is inconsistent with the spacing between two adjacent slots on the tray 5. Therefore, it is necessary to reposition the inductor components and adjust the spacing between adjacent inductor components.
[0039] Multiple suction holes 231 on each material loading slot 23 are interconnected and simultaneously connected to a negative pressure pipe. After the inductor is placed in the material loading slot 23, air is drawn in at the suction holes 231, generating negative pressure, causing the inductor to move towards the suction holes 231. Since the multiple suction holes 231 are respectively located on one side and at the corner of the material loading slot, the inductor moves towards one side and at the corner of the material loading slot, so that the two adjacent sides of the inductor connect with the two adjacent sides of the material loading slot 23 and completely cover the suction holes 231. At the same time, the pitch-changing device 21 drives the material block 22 to complete the pitch change, so as to change the spacing between two adjacent inductors to adapt to the spacing between the two adjacent second grippers of the first clamping device 31 and the spacing of the slots on the material tray 5.
[0040] When placing the inductor, any residual powder on the inductor falls out through the elongated hole 233 to avoid affecting positioning. Each time an inductor is removed from the loading tank 23, the air needle 25 blows air into the loading tank 23 through the first opening 232 to clean any residual powder. Simultaneously, the suction pipe 24 absorbs the blown-out powder to prevent environmental pollution.
[0041] The unloading mechanism 3 includes a first transfer device 31 and an unloading plate 32. A plurality of second grippers 311 are connected to the first transfer device 31. The second grippers 311 move along the first direction S1 between the loading block 22 and the unloading plate 32 under the drive of the first transfer device 31. Pressure sensors are provided on the second grippers 311.
[0042] The unloading mechanism 3 also includes a first hopper 33 and a second hopper 34 disposed on both sides of the unloading plate 32 in the second direction S2. A first conveying device 331 is disposed at the bottom of the first hopper 33; a second conveying device 341 is disposed at the bottom of the second hopper 34. Both the first conveying device 331 and the second conveying device 341 are connected to the unloading plate 32. The unloading mechanism 3 also includes a second transfer device 35 driven in the second direction S2, and two push rods 351 connected to the second transfer device 35. The push rods 351 are connected to the second transfer device 35 through a first cylinder 352 driven in the vertical direction.
[0043] In this embodiment, the empty tray 5 is stored in the first hopper 33. The first transfer device 31 transfers the empty tray 5 to the side of the unloading plate 32. The first cylinder 352 drives the push rod 351 to move downward, and under the drive of the second transfer device 35, pushes the tray 5 onto the unloading plate 32. The first transfer device 31 drives the second gripper 311 to grip the inductor on the loading block 22, and in conjunction with the third transfer device 312, transfers it into the tray 5, filling the tray 5. Afterward, the first cylinder 352 drives the push rod 351 to move downward again, and under the drive of the second transfer device 35, drives the tray 5 at the unloading plate 32 to the second conveying device 341, which then conveys the tray 5 to the second hopper 34 for temporary storage.
[0044] The second transfer device 35 simultaneously drives two push rods 351 to move. That is, while the empty tray 5 moves from the first conveying device 331 to the unloading plate 32, the tray 5 on the unloading plate 32, which is full of inductor components, is pushed to the second conveying device 341.
