[0031] An ejection chamber 15 is disposed in the rotating seat 1 . A plurality of ejection rods 16 are movably disposed in the ejection chamber 15 . The upper end of each ejection rod 16 extends to the outside of the ejection chamber 15 .

[0032] In this embodiment, when the circuit board needs to be processed, the pull plate 11 is pulled, and the pull plate 11 drives the two limit plates 13 to move, each limit plate 13 drives the pull rod 9 to move, and the pull rod 9 drives the adjustment seat 8 to move along the adjustment chamber 7. The first spring 10 is compressed, and the adjustment seat 8 drives the clamping plate 14 to move, so that the clamping plate 14 is separated from the positioning plate 6. The circuit board to be processed is placed on the rotating seat 1, and one side of the circuit board is in contact with the two positioning plates 6. One end of the bidirectional screw 3 passes through the moving chamber 2 and is fixedly connected to the turning handle 28. The turning handle 28 is turned, and the turning handle 28 drives the bidirectional screw 3 to move. The screw rod 3 rotates. Since the two-way screw rod 3 is provided with two threaded areas in opposite directions, the two moving seats 4 move in adjacent directions along the moving chamber 2. The moving seat 4 drives the adjustment block 5 to move. The adjustment block 5 drives the two pull rods 9 to move along the limit groove 12, so that the two adjustment blocks 5 cooperate to clamp and fix the left and right sides of the circuit board. The pull plate 11 is released. Under the action of the first spring 10, the adjustment seat 8 moves toward the positioning plate 6. The adjustment seat 8 drives the clamping plate 14 to move, so that the clamping plate 14 cooperates with the positioning plate 6 to clamp and fix the front and back sides of the circuit board. Thus, circuit boards of different sizes can be fixed.

[0033] More specifically, circuit boards of different sizes can be positioned and fixed by adjusting the positions of the two adjustment blocks 5 and the two clamping plates 14. The circuit board can be released by the opposite operation, and the four ejection rods 16 move upward and push the circuit board upward, so that the distance between the circuit board and the rotating seat 1 becomes larger, thereby facilitating its removal.

[0034] See also Figure 1-5 As an implementation method for moving the ejector rod 16: an ejector plate 17 is slidably connected to the ejector chamber 15 through a track structure, the upper end of the ejector plate 17 is fixedly connected to multiple ejector rods 16, and multiple second springs 18 are fixedly connected between the upper end of the ejector plate 17 and the ejector chamber 15. A convex column 19 is rotatably provided in the ejector chamber 15, and a rotating rod 20 is fixedly provided on one side of the convex column 19, and one end of the rotating rod 20 extends to the outside of the ejector chamber 15.

[0035] Specifically, the rotating rod 20 is rotated, and the rotating rod 20 drives the convex column 19 to rotate in the ejection chamber 15. When the protruding part of the convex column 19 contacts the ejection plate 17, as the convex column 19 rotates, the convex column 19 pushes the ejection plate 17 upward, the second spring 18 is compressed, and the ejection plate 17 moves upward along the sliding connection with the ejection chamber 15. The ejection plate 17 drives the multiple ejection rods 16 to move upward, thereby pushing the circuit board upward. When the rotating rod 20 is released, the ejection plate 17 and the ejection rods 16 move back to their original positions under the push of the second spring 18, and the downward thrust of the ejection plate 17 causes the convex column 19 to rotate back to its original position.

[0036] See also Figure 1-5 As an implementation method for rotating the position of the circuit board: a base 21 is rotatably provided at the lower end of the rotating seat 1, a gear ring 22 is fixedly provided on the outer side of the rotating seat 1, a fixed ring 23 matching the gear ring 22 is movably provided on the outer side of the gear ring 22, a lifting ring 24 is fixedly provided at the lower end of the fixed ring 23, a pushing chamber 25 is provided at the upper end of the base 21, the lower end of the lifting ring 24 is inserted into the pushing chamber 25 and fixedly connected to a limiting ring 26, the limiting ring 26 is slidably connected to the pushing chamber 25 through a track structure, and a plurality of third springs 27 are fixedly connected between the limiting ring 26 and the pushing chamber 25.

[0037] Specifically, when it is necessary to rotate the position of the circuit board during the processing of the circuit board, the fixed ring 23 is pushed downward, so that the fixed ring 23 drives the lifting ring 24 to move downward along the sliding connection with the pushing chamber 25, and the lifting ring 24 drives the limiting ring 26 to move downward, and the third spring 27 is compressed. At this time, the fixed ring 23 is separated from the gear ring 22, and the rotating seat 1 is rotated. The rotating seat 1 drives the clamped circuit board to rotate. When the rotation is completed, the fixed ring 23 is released, and under the push of the third spring 27, the limiting ring 26 drives the lifting ring 24 and the fixed ring 23 to move back to their original positions. The limiting ring 26 is limited by the sliding connection with the pushing chamber 25, so that it cannot rotate in the pushing chamber 25. The limiting ring 26 rotates the fixed ring 23 through the lifting ring 24, and the fixed ring 23 fixes and limits the gear ring 22. At this time, the rotating seat 1 cannot rotate.

[0038] To sum up, when the overall equipment is in use:

[0039] When the circuit board needs to be positioned and fixed when it needs to be processed, pull the pull plate 11, the pull plate 11 drives the two limit plates 13 to move, each limit plate 13 drives the pull rod 9 to move, the pull rod 9 drives the adjustment seat 8 to move along the adjustment chamber 7, the first spring 10 is compressed, and the adjustment seat 8 drives the clamping plate 14 to move, so that the clamping plate 14 is away from the positioning plate 6, the circuit board to be processed is placed on the rotating seat 1, and one side of the circuit board is in contact with the two positioning plates 6, one end of the bidirectional screw 3 passes through the moving chamber 2 and is fixedly connected to the turning handle 28, the turning handle 28 is turned, and the turning handle 28 brings The moving bidirectional screw 3 rotates. Since the bidirectional screw 3 is provided with two threaded areas in opposite directions, the two moving seats 4 move in adjacent directions along the moving chamber 2. The moving seat 4 drives the adjustment block 5 to move. The adjustment block 5 drives the two pull rods 9 to move along the limit groove 12, so that the two adjustment blocks 5 cooperate to clamp the left and right sides of the circuit board. The pull plate 11 is released. Under the action of the first spring 10, the adjustment seat 8 moves toward the positioning plate 6. The adjustment seat 8 drives the clamping plate 14 to move, so that the clamping plate 14 cooperates with the positioning plate 6 to clamp the front and back sides of the circuit board. In this way, circuit boards of different sizes can be fixed. After the processing of the circuit board is completed, the opposite operation can be used to release the circuit board.

[0040] When it is necessary to adjust the angle of the positioned and fixed circuit board, the fixing ring 23 is pushed downward so that the fixing ring 23 drives the lifting ring 24 to move downward along the sliding connection with the pushing chamber 25, the lifting ring 24 drives the limiting ring 26 to move downward, and the third spring 27 is compressed. At this time, the fixing ring 23 is separated from the gear ring 22, and the rotating seat 1 is rotated. The rotating seat 1 drives the clamped and fixed circuit board to rotate. When the rotation is completed, the fixing ring 23 is released. Under the push of the third spring 27, the limiting ring 26 drives the lifting ring 24 and the fixing ring 23 to move back to their original positions. The limiting ring 26 is limited by the sliding connection with the pushing chamber 25 so that it cannot rotate in the pushing chamber 25. The limiting ring 26 rotates the fixing ring 23 through the lifting ring 24, and the fixing ring 23 fixes and limits the gear ring 22. At this time, the rotating seat 1 cannot rotate.

[0041] When the circuit board is processed and needs to be removed, the circuit board is released from the clamping and fixed state, and the rotating rod 20 is rotated. The rotating rod 20 drives the convex column 19 to rotate in the ejection chamber 15. When the protruding part of the convex column 19 contacts the ejection plate 17, as the convex column 19 rotates, the convex column 19 pushes the ejection plate 17 upward, the second spring 18 is compressed, and the ejection plate 17 moves upward along the sliding connection with the ejection chamber 15. The ejection plate 17 drives the multiple ejection rods 16 to move upward, thereby pushing the circuit board upward, so that the distance between the circuit board and the rotating seat 1 becomes larger, so that it is easy to remove. When the rotating rod 20 is released, the ejection plate 17 and the ejection rod 16 move back to their original positions under the push of the second spring 18, and the downward thrust of the ejection plate 17 causes the convex column 19 to rotate back to its original position.

[0042] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described here one by one. In the above, all fixed connections are preferably welded. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model. The scope of the utility model is defined by the attached claims and their equivalents.
