[0035] To make the above and other objects, features and advantages of the present invention more apparent, embodiments of the present invention are described below in detail with reference to the accompanying drawings.

[0036] Example 1

[0037] like Figure 1 and Figure 2 As shown, the PCB board clamp of this embodiment includes a fixed arm 1 (first clamping arm) and a movable arm 2 (second clamping arm) connected to the fixed arm 1 via a hinge shaft. The movable arm 2 can rotate around the hinge shaft (not shown), thereby clamping or releasing with the fixed arm 1. A compression spring 3 is provided between the fixed arm 1 and the movable arm 2. One end of the compression spring 3 abuts against the fixed arm 1, and the other end abuts against the movable arm 2, providing a force to clamp the fixed arm 1 and the movable arm 2 together, so that the clamp can be in a clamped state. When the external force applied to the movable arm 2 overcomes the elastic force of the compression spring 3, the clamp can be opened. The compression spring 3 is located above the hinge shaft.

[0038] The fixed arm 1 has a fixed arm hinge connecting part 1-1 extending from the fixed arm 1 to the movable arm 2, and the movable arm 2 has a movable arm hinge connecting part 2-1 extending from the movable arm 2 to the fixed arm. The fixed arm hinge connecting part 1-1 and the movable arm hinge connecting part 2-1 are connected by a hinge. A clamp stabilizing protrusion 4 is arranged on both sides of the hinge, protruding from both sides of the fixed arm 1 in a direction parallel to the axis of the hinge. The clamp stabilizing protrusion 4 can be directly or indirectly connected to the fixed arm 1. In this embodiment, the clamp stabilizing protrusion 4 is arranged on the fixed arm hinge connecting part 1-1. In other embodiments, if the movable arm hinge connecting part 2-1 is located outside the fixed arm hinge connecting part 1-1, the clamp stabilizing protrusion 4 can be arranged on the movable arm hinge connecting part 2-1, indirectly connected to the fixed arm hinge connecting part 1-1 through the movable arm hinge connecting part 2-1.

[0039] Embodiment 2

[0040] As shown in Figure 3 and Figure 4 , the difference between this embodiment and Embodiment 1 is that the clamp stabilizing protrusion 4 of this embodiment is integrated with the fixed arm 1, and the clamp stabilizing protrusion 4 is arranged on the fixed arm 1. The fixed arm hinge connecting part 1-1 and the movable arm hinge connecting part 2-1 are connected by a hinge 5. The clamp stabilizing protrusion 4 is arranged on the middle and lower part of the fixed arm 1, below the compression spring 3, and near the hinge 5, i.e. the projection of the hinge 5 on the plane where the fixed arm 1 is located (a plane perpendicular to the axis of the compression spring) is within the projection range of the clamp stabilizing protrusion 4 on the plane where the fixed arm 1 is located.

[0041] Embodiment 3

[0042] As shown in Figure 5 , the difference between this embodiment and Embodiments 1 and 2 is that the PCB clamping jig of this embodiment is a self-locking type, and a locking mechanism 6 is arranged on the clamp, and the compression spring acts on the locking mechanism 6. Compared with conventional self-locking type clamps, this embodiment is provided with a clamp stabilizing protrusion 4 on the fixed arm 1, and the clamp stabilizing protrusion 4 is connected to the fixed arm 1 by a threaded fastener.

[0043] Embodiment 4

[0044] As shown in Figure 6 , the difference between this embodiment and Embodiment 3 is that the clamp stabilizing protrusion 4 of this embodiment is connected to the fixed arm 1 by welding.

[0045] Embodiment 5

[0046] Referring to Figure 7 and Figure 8The embodiment provides the clamp stabilizing mechanism of the PCB clamp.

[0047] The clamp stabilizing mechanism comprises a first stabilizing protrusion clamping portion 7, a second stabilizing protrusion clamping portion 8, a first clamping portion mounting frame 9 and a second clamping portion mounting frame 10. The first stabilizing protrusion clamping portion 7 and the second stabilizing protrusion clamping portion 8 are oppositely arranged and can move relative to each other in the horizontal direction, so as to clamp the clamp stabilizing protrusion 4 on the PCB clamp. The first stabilizing protrusion clamping portion 7 and the second stabilizing protrusion clamping portion 8 of the embodiment are both in U-shaped and symmetrical structures. The first stabilizing protrusion clamping portion 7 is arranged on the first clamping portion mounting frame 9, and the second stabilizing protrusion clamping portion 8 is arranged on the second clamping portion mounting frame 10. The first clamping portion mounting frame 9 is driven by a moving driving unit (not shown) to move in the horizontal direction, and the second clamping portion mounting frame 10 is also driven by a moving driving unit (not shown) to move in the horizontal direction. The two can translate towards each other or away from each other, so as to clamp or release the clamp stabilizing protrusion 4 on the PCB clamp. When the clamp stabilizing protrusion 4 on the PCB clamp is clamped, the first stabilizing protrusion clamping portion 7 and the second stabilizing protrusion clamping portion 8 can stabilize the PCB clamp. A plurality of stabilizing protrusion clamping portions can be arranged on the clamping portion mounting frame at the same time, so as to stabilize a plurality of PCB clamps at the same time and keep the consistency of the positions of the PCB clamps. The first and second clamping portion mounting frames can be controlled to move by a same moving driving unit through a synchronous transmission structure, or can be controlled to move by different moving driving units respectively. The moving driving unit can be a common mechanical driving unit such as an air cylinder, a motor or a push rod.

[0048] Embodiment 6

[0049] As Figure 9 and Figure 10As shown, the difference between this embodiment and embodiment 5 is that the first stabilizing protrusion clamping part 7 in this embodiment is U-shaped, and the second stabilizing protrusion clamping part 8 is a flat plate structure, which can be applied to the PCB board fixtures used in embodiments 2-4. The first stabilizing protrusion clamping part 7 is disposed on the first clamping part mounting bracket 9, and the second stabilizing protrusion clamping part 8 is disposed on the second clamping part mounting bracket 10. The first clamping part mounting bracket 9 is driven by a moving drive unit (not shown) and can move horizontally. The second clamping part mounting bracket 10 is also driven by a moving drive unit (not shown) and can move horizontally. The two can translate towards each other or away from each other, so that the first stabilizing protrusion clamping part 7 and the second stabilizing protrusion clamping part 8 clamp or release the clamping stabilizing protrusion 4 on the PCB board fixture. When clamping the clamping stabilizing protrusion 4 on the PCB board fixture, it can stabilize the PCB board fixture.

[0050] Example 7

[0051] like Figure 11 and Figure 12 As shown, the difference between this embodiment and embodiment 5 is that although both the first stabilizing protrusion clamping part 7 and the second stabilizing protrusion clamping part 8 are U-shaped, their lengths are different, which can be applied to the PCB board fixtures used in embodiments 2-4. Meanwhile, both the first stabilizing protrusion clamping part 7 and the second stabilizing protrusion clamping part 8 are directly connected to their respective moving drive units 11, which in this embodiment is a cylinder.

[0052] The plate clamps in the aforementioned embodiments are all asymmetrical offset clamps, that is, the first clamping arm and the second clamp are not symmetrical structures. One clamping arm is relatively fixed, and the other clamping arm rotates relative to the fixed clamping arm, thereby opening or closing. However, they can also be used for, for example Figure 13 In the symmetrical fixture shown, the fixture stabilizing protrusion 4 is provided on the hinge shaft connection part Q connected to the first clamping arm and the second clamping arm. The fixture stabilizing mechanism of Embodiment 5 can be used on such symmetrical plate fixtures.

[0053] Example 8

[0054] To facilitate the installation and positioning of the board fixture on the copper flat plate, the board fixture may also include a fixture positioning component. This component is mounted on the copper flat plate and is used to achieve the installation and positioning of the board fixture on the copper flat plate. For example... Figure 14 and Figure 15As shown, the clamp positioning assembly of this embodiment includes a copper flat plate 12 disposed opposite to the first clamping arm 1, and a clamp positioning pin 13 disposed on the copper flat plate 12. A positioning pin hole (not shown) is machined on the copper flat plate 12 for the clamp positioning pin 13 to pass through. The copper flat plate 12 is connected to the first clamping arm 1 by connecting bolts 14. In this embodiment, the connecting bolts 14 are disposed on the upper and lower parts of the copper flat plate 12. The copper flat plate 12 and the first clamping arm 1 are provided with threaded holes (not shown) with corresponding positions. The connecting bolts 14 pass through the threaded holes on the copper flat plate 12 and the first clamping arm 1, connecting the copper flat plate 12 and the first clamping arm 1 together, so that both the copper flat plate 12 and the first clamping arm 1 are disposed on the copper flat plate 100. In this embodiment, the positioning pin hole is located between the upper and lower threaded holes of the copper flat plate 12. After the fixture positioning pin 13 passes through the positioning pin hole, it presses against the copper flat plate 100 located between the copper flat plate 12 and the first clamping arm 1, thereby realizing the positioning of the plate fixture on the copper flat plate 100.

[0055] Example 9

[0056] like Figure 16 As shown, the difference between this embodiment and embodiment 8 is that the fixture positioning assembly of this embodiment includes a pair of L-shaped positioning clamps 15. The positioning clamps 15 are fixed to the copper flat plate 100 by fasteners (not labeled) such as screws or bolts. The cross-sectional shape of the positioning clamps 15 is L-shaped. The two positioning clamps 15 are located on both sides of the first clamping arm 1 of the plate clamp, clamping the first clamping arm 1 in the middle, thereby realizing the positioning of the plate clamp on the copper flat plate 100.

[0057] Example 10

[0058] like Figure 17 As shown, the difference between this embodiment and embodiments 9 and 10 is that the copper flat plate 100 in this embodiment is horizontally arranged instead of vertically arranged. The clamping positioning component in this embodiment is a positioning connecting bolt 16 that passes through the copper flat plate 100. The plate clamp has a horizontally arranged mounting plate 17. The mounting plate 17 and the copper flat plate 100 are machined with assembly holes (not shown) for the positioning connecting bolt 16 to pass through. After the positioning connecting bolt 16 passes through the mounting plate 17 and the copper flat plate 100, it cooperates with the nut (not labeled) to realize the installation and positioning of the plate clamp on the copper flat plate 100.
