[0022] Figure 1 1 is a schematic diagram of the first structure of the winding machine clamping feeding device of the utility model embodiment. It should be noted that if there is substantially the same result, the utility model is not based on Figure 1 The structure shown is limited.

[0024] In some embodiments, Figure 1 As shown, the clamping device 10 includes a first clamp 11 and a second clamp 12, and the telescopic device 20 includes a first telescopic rod 21 and a second telescopic rod 22, the first clamp 11 is connected to the first end of the first telescopic rod 21, the second clamp 12 is connected to the first end of the second telescopic rod 22, the second end of the first telescopic rod 21 is connected to the power device 30, and the second end of the second telescopic rod 22 is connected to the power device 30.
[0025] In this embodiment, the first clamp 11 and the second clamp 12 can cooperate with each other to clamp the coil 40 to be fed. The power device 30 can control the distance between the first clamp 11 and the second clamp 12 relative to the winding position by driving the first telescopic rod 21 and the second telescopic rod 22 to extend and retract, thereby controlling the distance between the coil 40 to be fed clamped by the first clamp 11 and the second clamp 12 and the winding position, which can ensure that the head end of the coil 40 to be fed does not shift before entering the winding position, thereby improving the stability of loading the coil 40 to be fed.

[0027] In some embodiments, Figure 1 As shown, the first clamping piece 11 and the second clamping piece 12 have the same size.
[0028] In this embodiment, the first clamping piece 11 and the second clamping piece 12 have the same size, so that the first clamping piece 11 and the second clamping piece 12 can better cooperate with each other when clamping the coil 40 to be fed.
[0029] In some embodiments, Figure 1 As shown, the first telescopic rod 21 and the second telescopic rod 22 have the same size.
[0030] In this embodiment, the first telescopic rod 21 and the second telescopic rod 22 have the same size, so that the first telescopic rod 21 and the second telescopic rod 22 can be at the same telescopic degree when extending or contracting, which is conducive to more stably allowing the clamping device 10 to send the clip to the winding position.
[0031] In some embodiments, Figure 1 As shown, in the coiling preparation state, the first clamping piece 11 and the second clamping piece 12 clamp the coiled material 40 to be fed, and the first telescopic rod 21 and the second telescopic rod 22 are in a retracted state.
[0032] In this embodiment, the coiling preparation state is the state when the coil 40 to be fed is ready to enter the winding needle 60. At this time, the coil 40 to be fed has not yet entered the winding needle 60, and the head end of the coil 40 to be fed needs to be clamped and fed to ensure that the head end of the coil 40 to be fed does not deviate when entering the winding needle 60. In this state, the first clamp 11 and the second clamp 12 are in a clamping state, clamping the coil 40 to be fed, and the first telescopic rod 21 and the second telescopic rod 22 are in a retracted state.
[0033] In some embodiments, the second structural diagram of the winding machine clamping feeding device of the utility model embodiment is as follows Figure 2As shown, in the coiling process, the first clamping piece 11 and the second clamping piece 12 release the coil 40 to be fed, and the first telescopic rod 21 and the second telescopic rod 22 are in an extended state.
[0034] In this embodiment, the winding state is the state when the coil 40 to be fed is being wound in the winding needle 60, and the winding machine clamping feeding device of the utility model temporarily enters the standby state. In this state, the first clamp 11 and the second clamp 12 are in a non-clamping state, and the first telescopic rod 21 and the second telescopic rod 22 are in an extended state.
[0035] In some embodiments, a third structural diagram of the winding machine clamping feeding device of the utility model embodiment is as follows Figure 3 As shown, in the reeling state, the first clamping piece 11 and the second clamping piece 12 clamp the coiled material 40 to be fed, and the first telescopic rod 21 and the second telescopic rod 22 are in a retracted state.
[0036] In this embodiment, the winding state is the state when the coil 40 to be fed is about to be completely fed to the winding needle 60. At this time, the end of the coil 40 to be fed needs to be clamped and fed to ensure that the end of the coil 40 to be fed does not deviate when entering the winding needle 60. In this state, the first clamp 11 and the second clamp 12 are in a clamping state, clamping the coil 40 to be fed, and the first telescopic rod 21 and the second telescopic rod 22 are in a retracted state.
[0037] In a specific embodiment, whether the coiled material 40 to be fed is in the reeling state is determined by whether the remaining length of the coiled material 40 to be fed reaches a predetermined threshold, and the predetermined threshold can be freely set according to actual needs.
[0038] In some embodiments, a fourth structural diagram of the winding machine clamping feeding device of the utility model embodiment is as follows Figure 4 As shown, in the winding completion state, the first clamping piece 11 and the second clamping piece 12 release the coil 40 to be fed, and the first telescopic rod 21 and the second telescopic rod 22 are in an extended state.

At this time, the winding machine clamping feeding device of the utility model has completed the feeding work and entered the standby state, the first clamping piece 11 and the second clamping piece 12 are in a non-clamping state, and the first telescopic rod 21 and the second telescopic rod 22 are in an extended state.
[0040] In some embodiments, the winding machine clamping feeding device provided by the utility model further includes a detection control device. Figure 1-4 It is not clearly shown that the detection and control device is connected to the clamping device 10, the telescopic device 20 and the power device 30 respectively.
[0041] In this embodiment, the detection and control device is used to detect the position state of the coil 40 to be fed. When the detection and control device detects that the coil 40 to be fed is in the state of preparation for winding, the clamping device 10 clamps the coil 40 to be fed, and the power device 30 provides power to the telescopic device to retract; when the detection and control device detects that the coil 40 to be fed is in the state of winding, the clamping device 10 releases the coil 40 to be fed, and the power device 30 provides power to the telescopic device to extend; when the detection and control device detects that the coil 40 to be fed is in the state of winding, the clamping device 10 clamps the coil 40 to be fed, and the power device 30 provides power to the telescopic device to retract; when the detection and control device detects that the coil 40 to be fed is in the state of completion of winding, the clamping device 10 releases the coil 40 to be fed, and the power device 30 provides power to the telescopic device to extend.
[0042] In some embodiments, the power plant 30 includes a dual-shaft cylinder.
[0043] In this embodiment, the power device 30 includes a dual-axis cylinder, which is used to provide power for the telescopic device 20. The dual-axis cylinder can achieve more precise motion control and can occupy a smaller space.
[0044] The winding machine clamping and feeding equipment provided by the utility model first clamps the coil 40 to be fed through the clamping device 10, and then drives the telescopic device 20 to extend through the power device 30, so that the clamping device 10 follows the extension of the telescopic device 20 to the winding position, and finally releases the clamping device 10 to allow the coil 40 to enter the winding position, which can ensure that the head end of the coil 40 to be fed does not shift before entering the winding position; and when the coil 40 to be fed is about to be completely fed to the winding needle 60, the clamping device 10 can be used to clamp and feed the end of the coil 40 to be fed, so as to ensure that the end of the coil 40 to be fed does not shift when entering the winding needle 60, thereby improving the stability of feeding the coil 40 to be fed.
[0045] The winding machine clamping feeding device provided by the utility model can reduce the distance between the coil 40 to be fed and the winding needle 60 when it is rolled into the coil, thereby reducing the head and tail swinging phenomena in the winding process, and can effectively reduce the scrap rate of bad coating in the winding process and improve production efficiency.
[0046] The above is only an implementation method of the present invention. It should be pointed out that a person skilled in the art can make improvements without departing from the inventive concept of the present invention, but these improvements are all within the protection scope of the present invention.
