[0018] The utility model is further described below in conjunction with the accompanying drawings:

[0019] Referring to the accompanying drawings: This mica ring processing equipment includes a first frame 1, a second frame 2, and a guide bracket 3. The first frame 1 is provided with a discharge table 4 for placing a material sheet, and the second frame 2 is provided with a conveying track 5 close to the discharge table 4 and used to convey the material sheet, a punch head 6 located at the front end of the conveying track 5, and a stamping die 7 driven by the punch head 6. The guide bracket 3 is arranged on the first frame 1 and the second frame 2 at the same time, and an adsorption unit 8 is arranged on the upper end, which is located above the discharge table 4 and the conveying track 5 and can move along the width direction of the guide bracket 3. The adsorption unit 8 is used to replace the material sheet placed on the discharge table 4 to the conveying track 5. The conveying track 5 can move along the X-axis and Y-axis directions on the second frame 2, and a clamping unit for clamping the material sheet when conveying the material sheet is arranged at the end away from the stamping die 7. The principle of the utility model is that the material sheet is placed on the unloading table 4 in advance. When processing the mica ring, the adsorption unit 8 will transfer the material sheet placed on the unloading table 4 to the conveying track 5, so that there is no need for manual loading, and the material sheet is clamped by the clamping unit 9 when the material sheet is placed on the conveying track 5 to ensure the stability of the material sheet when being conveyed. After clamping, the conveying track 5 drives the material sheet to move in the direction of the stamping die 7, and the conveying track 5 has two running tracks on the second frame 2, one is the stamping feeding track for sending the material sheet to the stamping die 7, and the other is the adjustment track perpendicular to the stamping feeding track, that is, the stamping feeding track is on the Y axis, and the adjustment track is on the X axis. Because the width of the material sheet can support the processing of at least 6 columns of mica rings on the same material sheet, and two columns are processed at the same time, and there are at least 20 mica rings in each column, so that the material sheet is fully utilized, and the processing efficiency is very high in comparison.

[0020] A downwardly recessed placement cavity 41 is provided in the material discharging table 4. The placement cavity 41 extends along the length direction of the material discharging table 4. The material supply plate is placed in the placement cavity 41, and the placement cavity 41 has a U-shaped configuration. In this way, the depth that determines the number of placed material plates and the width that matches the width of the material plates can be obtained at the same time, so that the material plates are stably placed in the placement cavity 41, which is convenient for the adsorption unit 8 to take.

[0021] The adsorption unit 8 includes a movable plate 81, a connecting plate 82, and a plurality of suction cups 83. The movable plate 81 is arranged at the upper end of the guide bracket 3, and a first cylinder 81-a symmetrically distributed on both sides of the guide bracket 3 is arranged on its upper surface. The piston rod of the first cylinder 81-a passes downward through the movable plate 81 and is connected to the connecting plate 82 and drives the connecting plate 82 to move vertically. The suction cups 83 are all arranged on the connecting plate 82. After the adsorption unit 8 adsorbs the material plate, the movable plate 81 moves to replace the material plate to the conveying track 5. The connecting plate 82 moves up and down under the drive of the first cylinder 81-a, so that it moves down when adsorbing the material plate so that the suction cup 83 can be adsorbed on the material plate, and moves up after adsorption to avoid interference during the replacement process. At the same time, the suction cup 83 is connected to an air compressor, so that the suction cup 83 can generate a strong adsorption force when adsorbed on the material plate, thereby ensuring the stability of adsorption.

[0022] A plurality of connecting blocks 82-a are arranged on the lower surface of the connecting plate 82 and are evenly distributed along its length direction. Both ends of the connecting blocks 82-a have suction cup connecting positions for connecting the suction cup 83. The connecting blocks 82-a can provide a clear installation position for the suction cup 83, and the spacing between adjacent connecting blocks 82-a is also fixed. Therefore, when setting the suction cup 83, there is no need to adjust the use position of the suction cup 83. At the same time, the suction cup 83 is connected to the connecting block 82-a in a threaded connection manner, which also simplifies the connection method.

[0023] The clamping unit 9 includes a base plate 91, a second cylinder 92, and a clamping arm 93. The base plate 91 is arranged on the conveying track 5, the second cylinder 92 is arranged on the base plate 91 and is located in the center, one end of the clamping arm 93 is a connecting end arranged on the piston rod of the second cylinder 92, and the other end is a clamping end acting on the material plate, the base plate 91 is used to set the second cylinder 92, and the second cylinder 92 is used to drive the clamping arm 93, that is, the clamping arm 93 performs a clamping action when the piston rod of the second cylinder 92 moves up (the clamping arm 93 swings in the direction close to the material plate), and performs a releasing action when the piston rod of the second cylinder 92 moves down (the clamping arm 93 swings in the direction away from the material plate), and at the same time, the stroke of the piston rod of the second cylinder 92 is fixed, and its state can be continuously maintained in the absence of an execution command, that is, the clamping action can be continuously maintained in the clamping state.

[0024] The width of the clamping arm 93 gradually widens from the connecting end to the clamping end, and two extension heads 93-a symmetrically distributed on both sides are provided at the clamping end. This arrangement allows the applicable width of the clamping arm 93 to be close to the width of the material sheet, and the extension head 93-a is used to increase the usable length of the clamping arm 93, so that the working position of the clamping arm 93 is not at the end, and the clamping stability that can be provided after clamping the material sheet is good.

[0025] A guide roller 91 - a is provided on the base plate 91 and is located at the front end of the second cylinder 92 and is used to provide lower support for the clamping arm 93 . The guide roller 91 - a is used to provide lower support for the clamping arm 93 , thereby avoiding destructive changes such as bending of the clamping arm 93 caused by the drive of the second cylinder 92 .

[0026] Limit blocks 51 for limiting the width of the material sheet are arranged on both sides of the conveying track 5. An L-shaped placement groove 51-a is arranged in the limit block 51 to provide restrictions on the left and right ends of the material sheet to prevent it from swinging when being conveyed, and can also raise the use position of the material sheet to achieve the same horizontal height as the upper surface of the bottom plate 91.
