Description

Technical Field

[0001] This invention relates to the field of automated processing equipment technology, and in particular to an automatic assembly device for coil stator laminations mounted on a medium plate. Background Technology

[0002] The invention patent with publication number CN109597295A discloses an automatic feeding mechanism for watch coils. By using a tray to store coils and automatically feeding them onto the tray, this invention can be used in conjunction with automated watch assembly equipment to improve the efficiency and yield of coil installation into the movement, thereby reducing the assembly cost of watch movements. However, in actual use, due to the large number of components in the middle plate assembly, the above patent can only automatically feed the coils. The middle plate assembly still requires manual assembly. Currently, the production of the middle plate assembly is mainly completed by manual assembly, which is difficult to meet the needs of mass production.

[0003] This invention primarily addresses the automated installation of a specific type of midplate assembly, which includes a coil, a midplate, a sealing plate, and stator laminations. The coil is made of copper or aluminum wire with an insulating varnish coating and is positioned on one side of the midplate. The coil has an insertion hole inside, and the midplate has mounting grooves with protrusions within the grooves. The stator laminations are stator cores formed by stamping and stacking numerous sheet-like silicon steel plates, typically made of silicon steel, which effectively guides the magnetic field and reduces eddy current losses. The sealing plate and stator laminations have slots that match the protrusions. The stator laminations are divided into an open head and a closed tail, with the head structure identical to that of the sealing plate. During the assembly process, the sealing plate is first inserted into the mounting slot of the middle plate, and then the head of the stator plate is inserted through the insertion hole inside the coil and then inserted into the mounting slot. During the insertion process, the sealing plate slot is first inserted into the protrusion, and then the slot of the stator plate head is inserted into the protrusion. The surfaces of the stator plate and the sealing plate are in contact, and then the stator plate and the sealing plate are stacked and placed inside the slot. Because the slots on the middle plate are small, manual batch assembly can easily lead to fatigue. Manual assembly is prone to installation misalignment and incomplete installation, resulting in part positioning deviations, angular misalignments, and insufficient assembly accuracy.

[0024] The middle plate assembly device 5 includes: The middle plate feeding mechanism 51 is set on the frame 1 and is used to feed the middle plate to the middle plate suction station 51. The feeding is carried out by a common feeding tray, which is the prior art and will not be described in detail here. In actual use, after the middle plate is transported to the end of the conveyor line, the middle plate is pushed to the suction station by a pusher on one side, which facilitates the operation of the subsequent rotating mechanism 52. The pusher may include a combination of a drive and a pusher block. The output end of the drive is connected to the pusher block, and the pushing surface of the pusher block abuts against the middle plate. The rotating mechanism 52 is mounted on the frame 1 and is located between the conveying device 2 and the middle plate feeding mechanism 51.

The stator lamination feeding mechanism 71 includes a feeding tray, and a pushing block is provided on one side of the end of the feeding tray. The pushing block is driven by an external drive cylinder. The pushing block is provided with a groove that matches the stator lamination. After the stator lamination is fed into the slot, the cylinder pushes the pushing block to move the stator lamination to the appropriate position. The width of the pushing block is smaller than the length of the stator lamination, so that the subsequent clamping components can clamp the head end of the stator lamination for flipping. The second flipping mechanism 72 is mounted on the frame and located at the discharge end of the stator lamination feeding mechanism 71. It is used to clamp and flip the head of the stator lamination located at the flipping station 711. The second flipping mechanism 72 may include a gripper for clamping one end of the silicon steel sheet and a rotating component for driving the gripper to rotate. The output end of the rotating component is connected to the gripper.

It is used to transfer the flipped stator lamination to the tooling position 3, and to pass the head end of the stator lamination through the insertion hole and install it into the slot of the middle plate. In actual use, this movement can be achieved by a robot. When the stator lamination is pre-inserted, a sealing plate is installed at one end of the middle plate, and the head end of the stator lamination is pre-positioned above the sealing plate. The fixing mechanism 75 is used to fix other intermediate plate assemblies when the stator segments are inserted into the coil, so as to prevent the stator segments from running off-center.

[0027] The insertion mechanism 74 includes a push plate 741 and a pusher 742; the pushing surface of the push plate 741 abuts against the head end of the stator lamination; the pusher 742 is used to push the head end of the stator lamination out of the coil insertion hole and install it into the slot of the middle plate; the output ends of the push plate 741 and the pusher 742 are connected.

[0028] The middle plate is provided with an installation groove surface and a middle plate surface for stacking stator laminations and sealing laminations, wherein the installation groove surface is provided with a protrusion for further securing the stator laminations.

[0029] Working principle: The feeding mechanism 41 conveys the coil, and the first transfer mechanism 42 uses the suction cup 422 and the first gripper 421 at the bottom to pick up the coil surface (referring to the circuit board surface). Then, the picked-up coil is placed on the tooling position 3 of the conveying device 2. At this time, the conveying device 2 rotates the tooling clockwise.

[0030] 1. The middle plate assembly device 5 unloads the middle plate onto the middle plate suction station 51. During the process of the middle plate being moved by the second transfer mechanism 53, the rotating mechanism drives the middle plate to rotate 90° and place it into the tooling station 3.

[0031] 2. The sealing sheet feeding mechanism 61 feeds the sealing sheet and the third transfer mechanism 62 installs the sealing sheet into the mounting groove of the middle plate.

[0032] 3. During the stator lamination assembly process, the stator lamination feeding mechanism 71 feeds the stator laminations, the second flipping mechanism 72 clamps the head of the stator lamination and rotates it; the preset mechanism 73 moves the stator lamination above the tooling position 3 and simultaneously inserts the head end of the stator lamination into the coil insertion hole; after the conveying device 2 rotates, the insertion mechanism 74 pushes the head end of the stator lamination out of the insertion hole and installs it into the slot of the middle plate.

[0033] IV. During the process of stacking the sealing plates and stator plates in the middle plate mounting slot, the fixing mechanism 75 limits and fixes the surface of the middle plate to prevent deviation during the insertion of the stator plates. After completing the above workflow, the tooling position 3 on the conveying device 2 rotates to the next position, and then the unloading operation is carried out. Content not described in detail in this specification belongs to prior art known to those skilled in the art.
