Description

Technical Field

[0001] This utility model relates to manufacturing equipment in VCM coil production, and in particular to an automatic double-sided winding device for VCM coil winding machines. Background Technology

[0002] Existing VCM coils are characterized by their simple structure and small size. However, traditional VCM coil winding machines with double-sided winding devices have significant drawbacks in VCM coil winding operations. First, manual handling of the VCM coil products is required to change their sides before winding, resulting in low efficiency and potential visual fatigue and misoperation due to prolonged operation. Second, manual handling of the VCM coil products exposes the workers to potential hidden damage. Third, the machine heavily relies on individual worker skills and stability, requiring a high level of proficiency, leading to poor quality stability, difficulty in mastering the operation, and high costs, significantly impacting mold production efficiency and costs. Fourth, the component controlling the copper wire routing rotates around the product, easily causing uneven wire arrangement and a high defect rate. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides a double-sided automatic side-winding device for VCM coils. This device not only reduces manual contact with VCM coil products by realizing automatic double-sided side-winding of VCM coil products, thereby reducing the product defect rate, but also ensures the neatness of the wire arrangement when the rotating needle of the VCM coil product is stationary, thereby further improving the product yield.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A VCM coil double-sided automatic side-winding device includes a product fixing device, a product limiting device, and a product edge-changing device; wherein...

[0006] The product fixing device includes a product clamping fixture, a product rotating table, and a rotating base; the product is fixed in the product clamping fixture, and the product clamping fixture is installed in the product rotating table; the product rotating table is fixed on the rotating base, and the rotating base is connected to a first servo motor, and the rotating base is the first rotation center axis of the first servo motor.

[0007] The product limiting device includes a product limiting shaft and a rotary table limiting assembly; the product limiting shaft is connected to a second servo motor, and the product limiting shaft is the second rotation center shaft of the second servo motor, and the second servo motor drives the product limiting shaft 310 to perform forward and backward extension and retraction movements to press against the product or detach from the product.

[0008] A rotary table limiting assembly includes a limiting rotating block, a relief plate, and a spring. The limiting rotating block is located below the product rotary table, and the spring abuts against the lower part of the limiting rotating block. A first displacement control mechanism controls the movement of the relief plate located outside the limiting rotating block. When the relief plate is engaged with the limiting rotating block, the limiting rotating block moves backward in conjunction with the relief plate. When the relief plate moves to disengage from the limiting rotating block, the limiting rotating block moves forward under the action of the spring until it abuts against the product rotary table.

[0009] The product changing device includes a product rotating shaft and a rotating fixture; the product rotating shaft is fixedly connected to the product rotating table, and a second displacement control mechanism controls the movement of the rotating fixture. After the product completes the initial winding, the rotating fixture moves to the position of the product rotating table and is connected to the product rotating shaft. The rotation of the rotating fixture drives the product rotating table to rotate.

[0010] The product rotation axis is the third rotation center axis of the product rotation table, which is set perpendicular to the second rotation center axis; the first rotation center axis and the second rotation center axis are concentric and coaxial, and the first rotation center axis and the second rotation center axis have the same rotation direction and rotation speed in the working state.

[0011] As described above, in a VCM coil double-sided automatic side-winding device, a limiting block is protruding on the side of the limiting rotating top block, and a relief plate is provided on the outside of the limiting block corresponding to the limiting block.

[0012] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects:

[0013] First, the VCM coil double-sided automatic side-winding equipment of this utility model, through the cooperation of the product limiting device and the product changing device, not only realizes the automatic double-sided side-winding of products, but also reduces the contact between humans and products, thereby improving the yield rate.

[0014] Secondly, the product fixing device and product limiting device of this utility model can restrict the movement of the product back and forth and up and down. When the rotating needle of the product is stationary, the lines are arranged more neatly, which improves the yield of the product. Attached Figure Description

[0025] Now combined Figures 1 to 4 As shown, this utility model describes a double-sided automatic side-winding device for VCM coils, including a product fixing device 200, a product limiting device 300, and a product side-changing device 400.

[0026] The product fixing device 200 of this utility model includes a product clamping fixture 210, a product rotating table 220, and a rotating base 230. The product 100 is fixed in the product clamping fixture 210, which is clamped within the product rotating table 220. The product rotating table 220 limits the forward, backward, left, and right movement of the product clamping fixture 210. The product rotating table 220 is fixed on the rotating base 230, which is connected to a first servo motor 500. The rotating base 230 is the first rotation center axis of the first servo motor 500.

[0027] The product limiting device 300 of this utility model includes a product limiting shaft 310 and a rotary table limiting assembly. The product limiting shaft 310 is connected to a second servo motor 600. The product limiting shaft 310 is the second rotation center shaft of the second servo motor 600, and the second servo motor 600 drives the product limiting shaft 310 to perform forward and backward extension movements to press against the product 100, restricting the movement of the product 100, or disengaging from the product 100. The rotation of the product rotary table 220 drives the product 100 to complete the side-changing and winding process. The first rotation center shaft of the first servo motor 500 and the second rotation center shaft of the second servo motor 600 are concentric and coaxial, and the rotation direction and rotation speed of the first rotation center shaft and the second rotation center shaft are the same in the working state. The first servo motor 500 and the second servo motor 600 are connected to a VCM coil double-sided automatic side-winding controller (using the YASKAWA SGD7S-5R5A10B202 chip).

[0028] The rotary table limiting assembly includes a limiting rotating top block 320, a relief plate 330, and a spring 340. The limiting rotating top block 320 is disposed below the product rotary table 220, and the spring 340 abuts against the lower part of the limiting rotating top block 320 to achieve elastic back-and-forth movement of the limiting rotating top block 320. The relief plate 330 is disposed on the outer side of the limiting rotating top block 320. A limiting block 321 protrudes from the side of the limiting rotating top block 320, and the relief plate 330 is disposed on the outer side of the limiting rotating top block 320 corresponding to the limiting block 321. The relief plate 330 is connected to a first displacement control mechanism to control the back-and-forth and up-and-down movement of the relief plate 330. When the retracting plate 330 moves to engage with the limiting rotating block 320, the retracting plate 330 moves backward simultaneously with the limiting rotating block 320, thereby releasing the limiting rotating block 320 from its constraint on the product rotating table 220; or when the retracting plate 330 moves to disengage from the limiting rotating block 320, the limiting rotating block 320 moves forward under the action of the spring 340 until it abuts against the product rotating table 220, thus limiting the product rotating table 220. The first displacement control mechanism is connected to the VCM coil double-sided automatic side-winding controller.

[0029] The product edge-changing device 400 of this utility model includes a product rotation shaft 420 and a rotation fixture 410. The product rotation shaft 420 is fixedly connected to the product rotation table 220, and the product rotation shaft 420 is the third rotation center axis of the product rotation table 220. This third rotation center axis is arranged perpendicular to the second rotation center axis of the second servo motor 600. The rotation fixture 410 is connected to a second displacement control mechanism to control the forward and backward and up and down movement of the rotation fixture 410. The second displacement control mechanism is connected to a VCM coil double-sided automatic side-winding controller. After the product 100 completes the initial winding, the rotation fixture 410 moves to the position of the product rotation table 220 and connects to the product rotation shaft 420. The rotation of the rotation fixture 410 drives the product rotation table 220 to rotate, and thus the product 100 also rotates to change edges.

[0030] The working steps of this utility model's VCM coil double-sided automatic side-winding device are as follows:

[0031] Step 1: Loading materials. Specifically, such as... Figure 1 As shown, the VCM coil double-sided automatic side winding equipment of this utility model is equipped with a clamp carrying a product fixture 210 that holds the product 100 and an automatic feeding rotating table 220 for the product.

[0032] Step Two: Moving the fixed product 100 and the product rotary table 220. Specifically, as follows... Figure 1As shown, the product limiting shaft 310 extends and presses against the product 100 to restrict the vertical movement of the product; the limiting rotating top block 320 presses against the product rotating table 220 to restrict the left and right rotation of the product rotating table 220.

[0033] Step 3: Winding the wire around the beginning of the product. Specifically, for example... Figure 1 As shown, when the winding begins on one side of the beginning of the product 100, the first servo motor 500 rotates clockwise and drives the rotating base 230. The product rotating table 220 fixed in the rotating base 230 also rotates accordingly. The product clamping fixture 210 and the product 100 also rotate clockwise together with the product rotating table 220. At the same time, the second servo motor 600 also rotates the product limiting shaft 310, completing the winding on one side of the beginning of the product 100.

[0034] Step 4: Release the movement of product 100 and product rotary table 220. Specifically, as follows... Figure 2 As shown, after the product 100 has circled around one side of the starting end, the product limiting shaft 310 is braked by the second servo motor 600 and retracts away from the product rotating table 220. At the same time, the retraction plate 330 moves and gets stuck on the limiting block 321 of the limiting rotating top block 320. When the retraction plate 330 moves backward, it will drive the limiting rotating top block 320 away from the product rotating table 220.

[0035] Step 5: Product Reversal. Specifically, the rotating jig 410 moves under the product rotary table 220 and locks the product rotating shaft 420. The rotating jig 410 rotates 180° clockwise, which will cause the product rotating shaft 420 to rotate 180° clockwise. The rotation of the product rotating shaft 420 will cause the product rotary table 220 to rotate 180° clockwise as well, and the product 100 will also rotate 180° clockwise, completing the reversal.

[0036] Step Six: Moving the fixed product 100 and the product rotary table 220. Specifically, as follows... Figure 3 As shown, the retraction plate 330 moves forward and disengages from the limiting block 321 of the limiting rotating top block 320. At this time, the limiting rotating top block 320 loses the restriction of the retraction plate 330, and the spring 340 located below the limiting rotating top block 320 pushes the limiting rotating top block 320 forward to press against the product rotating table 220, thereby restricting the left and right rotation of the product rotating table 220; the product limiting shaft 310 extends out and presses against the product 100, thereby restricting the up and down movement of the product 100.

[0037] Step 7: Product terminal winding. When winding begins on the terminal side of product 100, the first servo motor 500 rotates clockwise, driving the rotating base 230. The product rotary table 220 fixed in the rotating base 230 also rotates accordingly. The product clamping fixture 210 and product 100 also rotate clockwise together with the product rotary table 220. At the same time, the second servo motor 600 also rotates the product limiting shaft 310, completing the winding on the terminal side of product 100.

[0038] Step 8: Product unloading. Specifically, after the winding of the product 100 on one end is completed, the clamp holding product fixture 210 of the VCM coil double-sided automatic side winding equipment of this utility model returns to the unloading position for unloading. The product fixture 210 automatically unloads the product 100.
