DETAILED DESCRIPTION

[0023] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by technicians in this field without creative work are within the scope of protection of the present invention.

[0024] In one embodiment, if Figures 1 to 7As shown, the conductive film preparation equipment provided by the present embodiment includes a base 1 and a motor base 2 arranged on the top of the base 1, a motor 3 is arranged in the motor base 2, a wheel disc 4 drivingly connected to the motor 3 is arranged on one side of the motor base 2, a reel 5 which can rotate synchronously with the motor shaft is fixed on the side of the wheel disc 4, at least three sinking grooves 6 are opened on the reel 5, the sinking grooves 6 surround the reel 5 and are evenly distributed, a support plate 7 is slidably installed on each sinking groove 6, the length of the support plate 7 is equal to the length of the sinking groove 6, and a row of vertical grooves in the groove cavity and along the length direction of the sinking groove 6 are welded The first spring 8 extends in the radial direction of the reel 5, the inner end of the support plate 7 is connected to the sink groove 6, the outer end of the support plate 7 extends outside the sink groove 6, and the inner end of the support plate 7 is connected to the first spring 8, so that the inner end of the support plate 7 is elastically connected to the sink groove 6, and the support plate 7 is slidably fitted in the sink groove 6 and the support plate 7 can slide back and forth in the sink groove 6 in the radial direction away from the reel 5 or close to the reel 5 under the elastic action of the first spring 8; a limiting ring 9 is fixed on the end surface of the wheel disc 4 facing the reel 5, the limiting ring 9 surrounds the periphery of the support plate 7, and the inner periphery of the limiting ring 9 is circumferentially opposite to the periphery of the support plate 7. There is a gap between the two ends of the reel 5, and a winding drum 10 is provided on the outer side of all the support plates 7. The length of the winding drum 10 is adapted to the length of the support plates 7, and the first spring 8 acts on the support plates 7 to elastically support the support plates 7 so that the support plates 7 press against the inner circle of the winding drum 10 to tighten the winding drum 10 on the reel 5, and the winding drum 10 can rotate synchronously with the reel 5. The other end of the support plate 7 away from the wheel disc 4 is provided with a chamfer 11, and the chamfer 11 is an inclined surface inclined downward toward the outer end of the winding drum 10. In this embodiment, it can be seen that the use principle of placing the winding drum 10 on the reel 5 by using the present invention is: the winding drum 1 is placed on the reel 5. 0 is placed on the reel 5 along the support plate 7 from the chamfered end 11. Under the support of the first spring 8, the support plate 7 is away from the radial direction of the reel 5 to form an extrusion on the inner hole wall of the winding drum 10, so that the winding drum 10 is clamped on the reel 5 under the action of the tensioning force of the support plate 7 and will not fall off downward. When the motor 3 is powered on, the reel 5 will be used to rotate the winding drum 10, and the tensioning effect of the support plate 7 can be used to prevent the winding drum 10 from falling off when rotating with the reel 5, so that the conductive film made after the sputtering machine is wound on the winding drum 10 without causing the winding drum 10 to slip on the reel 5.

[0025] In another embodiment, Figure 2 , Figure 3As shown, since there are at least three insertion holes 12 in the annular array on the limiting ring 9, and the number of the insertion holes 12 matches the number of the support plates 7, and a plug rod 13 runs through each of the insertion holes 12, one end of the plug rod 13 extends to the inner side of the limiting ring 9 and corresponds to the outer side of the support plate 7, and the other end of the plug rod 13 extends to the outer side of the limiting ring 9 and is welded with a pressure block 14 for pushing the plug rod 13 so that its inner end moves toward the support plate 7. That is, when the pressure block 14 is applied with an extrusion force to force the plug rod 13 to move along the insertion hole 12 toward the direction of the reel 5, since the winding drum 10 is sleeved on the outer side of the reel 5 , so the insertion rod 13 will be inserted into the end of the winding drum 10, forming an external pressure on the winding drum 10, and the insertion rod 13 is also sleeved with a second spring 15, the inner end of the second spring 15 is against the outer circumferential surface of the limiting ring 9, and the outer end of the second spring 15 is against the pressure block 14, and the second spring 15 allows the insertion rod 13 to move in the direction of the reel 5 and return to the reverse position. Since the wheel 4 is provided with a rotating groove 16 on the end surface facing the reel 5, and the rotating groove 16 is matched with a rotating plate 17 that can rotate circumferentially around its groove, the rotating plate 17 is welded with a horizontally extending straight line extending in the direction of the reel 5. The baffle rod 18 is a cylindrical rod, that is, when the rotating plate 17 rotates, the baffle rod 18 will rotate synchronously with it, and the baffle rod 18 will rotate until it slowly approaches the pressure block 14. Since the pressure block 14 corresponds to the rotation trajectory of the baffle rod 18, and the pressure block 14 is provided with a wedge-shaped pressure-bearing surface 19 for contacting the baffle rod 18, that is, when the baffle rod 18 rotates with the rotating plate 17 until it contacts the pressure block 14 and continues to rotate along the wedge-shaped pressure-bearing surface 19 of the pressure block 14, the wedge-shaped pressure-bearing surface 19 will be used to apply pressure to the pressure block 14, forcing the pressure block 14 to move with the baffle rod 18 toward the radial direction of the reel 5, so as to prevent the pressure block 14 from moving in the radial direction of the reel 5. This squeezes the winding drum 10 placed on the outer periphery of the reel 5. There are at least three pressure blocks 14 and plug rods 13 connected thereto, and at least three blocking rods 18. Therefore, it is only necessary to apply a small rotation to the wheel 4 to squeeze these plug rods 13 in different directions on the winding drum 10 at the same speed and generate squeezing force on the winding drum 10. This squeezing force is applied from the outside to the inside to assist the tensioning force formed by the support plate 7 on the winding drum 10 from the inside to the outside, which can further prevent the winding drum 10 from slipping on the winding drum 5 or falling off from the winding drum 5 when the winding drum 5 rotates.

[0026] In order to facilitate the operation of the wheel 4 and make it rotate quickly, as Figure 4 , Figure 6As shown, an arc groove 20 is also provided on the end surface of the wheel disc 4 away from the reel 5, and the arc groove 20 is communicated with the rotating groove 16, and a handle 21 for driving it to rotate in the rotating groove 16 is fixed on the wheel disc 4, and the handle 21 extends horizontally toward one end of the motor 3, and a rotation space is left between the motor 3, and a groove 22 is provided on the pressing block 14, which is bent toward the axial direction of the insertion rod 13, and the blocking rod 18 squeezes the pressing block 14 or falls into the groove 22, so that the blocking rod 18 can be self-locked. After the conductive film is wound on the winding drum 10, the conductive film is wound on the winding drum 10. The pressure blocks 14 apply pressure in sequence, or the wheel 4 rotates to force the blocking rod 18 to leave the groove 22, so that under the action of the second spring 15, the pressure block 14 can be pushed to reset outward with the insertion rod 13 in the radial direction away from the reel 5, so that the extrusion end of the insertion rod 13 will be away from the winding drum 10, and the winding drum 10 will no longer be squeezed. The operator can quickly remove the winding drum 10 that has completed the winding of the conductive film from the reel 5, repeat the above operation mode to put the next winding drum 10 on the reel 5 to complete the same winding work of the conductive film in the same way. First, it is convenient for the reel 10 to be quickly installed on the reel 5 or quickly removed from the reel 5, and second, the reel 10 can be placed on the reel 5 to be locked, so as to improve work efficiency and prevent the conductive film from wrinkling due to the reel 10 slipping on the reel 5 during the winding process.

It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the protection scope of the present invention.
