[0020] The present invention will now be described in detail with reference to the accompanying drawings.

[0021] A vacuum coating machine for uniform coating, such as Figures 1-2 As shown, the system includes a coating substrate box. A feeding door is installed on the outer surface of the coating substrate box. The feeding door is connected to the vacuum coating substrate box via a hinge. A rotating spindle 1 is rotatably connected to the inner wall of the coating substrate box. Multiple hanging plates 2 are arranged vertically on the outer wall of the rotating spindle 1. An insertion hole for the rotating spindle 1 to pass through is opened at the center of the hanging plate 2. The inner wall of the insertion hole is in contact with the surface of the rotating spindle 1. The hanging plate 2 is slidably connected to the rotating spindle 1. A clamping mechanism for fixing the hanging plate 2 is provided between the insertion hole and the rotating spindle 1. Several receiving grooves 3 are arranged in a ring array on the upper end face of the hanging plate 2. A protruding rod 4 is detachably connected to the inner wall of the receiving groove 3. A threaded rod 16 is fixedly connected to the lower end face of the protruding rod 4. A threaded groove 17 is provided on the bottom wall of the receiving groove 3, which is threadedly connected to the threaded rod 16.

[0022] The clamping mechanism includes a groove 5 on the inner wall of the insertion hole, a movable groove 6 on the inner wall of the groove 5, a lead screw 7 rotatably connected to the inner wall of the movable groove 6, a nut seat 8 sleeved on the lead screw 7, a connecting rod 9 fixedly connected to one end of the nut seat 8 near the opening of the movable groove 6, and a clamping plate 10 fixedly connected to one end of the connecting rod 9 away from the nut seat 8. The clamping surface of the clamping plate 10 is arc-shaped, and the arc is consistent with the arc of the outer wall of the rotating spindle 1, so that the clamping plate 10 can be more stable when clamping. The hanging plate 2 is provided with a driving component for driving the lead screw 7 to rotate.

[0023] The driving component includes a knob 11 sleeved on the outer wall of the lead screw 7. The knob 11 is fixedly connected to the end of the lead screw 7 away from the clamp 10. A rotating groove 12 is provided on the inner wall of the moving groove 6 for the knob 11 to rotate and extend. Both the upper and lower ends of the rotating groove 12 are connected to the outside. The knob 11 extends a part of the knob 11 out of the rotating groove 12 through the position of the rotating groove 12 connected to the outside.

[0024] A stop block 15 is fixedly connected to one end of the lead screw 7 near the clamping plate 10. The stop block 15 can limit the end of the lead screw 7 to prevent the nut seat 8 from falling off the lead screw 7 due to rotation. A limit block 13 is fixedly connected to the side wall of the nut seat 8. A limit groove 14 is provided on the inner wall of the moving groove 6 for the limit block 13 to be inserted and moved. During the process of the nut seat 8 moving with the rotation of the lead screw 7, the limit block 13 will be inserted into the limit groove 14 to move, making the nut seat 8 more stable during the movement.

[0025] Working principle: When the hanging plate 2 is in a fixed state, the clamping plate 10 clamps the rotating spindle 1 between the clamping plate 10 and the inner wall of the insertion hole, thus fixing the hanging plate 2 on the rotating spindle 1. To adjust the spacing of the hanging plates 2 according to the needs of hanging workpieces of different sizes and lengths, first, contact the part of the knob 11 extending from the rotating groove 12 with your finger, and push the knob 11. The knob 11 will then rotate the lead screw 7, which is fixedly connected to it. Through the nut seat 8 on the lead screw 7, the connecting rod 9 moves away from the rotating spindle 1. The connecting rod 9 then moves the clamping plate 10 away from the rotating spindle 1. As the clamping plate 10 moves away from the rotating spindle 1 along the inner wall of the groove 5, it can hold the rotating spindle... 1. Release the knob, and the hanging plate 2 can be moved up and down along the rotating spindle 1. After moving it to a suitable height, hold the hanging plate 2 with one hand and rotate the knob 11 in the opposite direction with the other hand to drive the lead screw 7 to rotate in the opposite direction. This causes the lead screw 7 to drive the connecting rod 9 and the clamping plate 10 to move closer to the rotating spindle 1 through the nut seat 8, until the clamping plate 10 cooperates with the inner wall of the insertion hole to clamp the rotating spindle 1. Release the knob 11 to stop the clamping plate 10 in the current position. The hanging plate 2 can then be fixed at this height. Then, hang the workpieces waiting to be coated one by one on the protruding rods 4 around the perimeter. This can meet the needs of hanging workpieces of different sizes, make full use of the internal space of the coating base box, improve the coating efficiency, and meet the needs of more situations.

[0026] Meanwhile, when the workpiece has different sizes and widths, the distribution interval of the protrusions 4 can be adjusted. The protrusions 4 and the receiving groove 3 are connected by threaded rods 16 and threaded grooves 17. Thus, the protrusions 4 can be disassembled and assembled by rotating them, so that the distribution interval and number of protrusions 4 can be arranged according to the actual situation, meeting the needs of more situations and making the hanging and adjustment more flexible.

[0027] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
