[0036] The present invention is now described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention. In the description of the present invention, it should be understood that, unless otherwise specified, the meaning of "multiple" is two or more.

[0037] See also Figure 1 A PCB circuit board detection fixture of a specific embodiment of the utility model includes a base 1, a fixed frame 2, an adjustment component 3 and a fixture component 4. The fixed frame 2 is arranged on the base 1, and a mounting position 24 is opened on the fixed frame 2. The mounting position 24 is suitable for arranging a PCB circuit board. The adjustment component 3 is connected to the fixed frame 2, and the adjustment component 3 can move along the Y direction of the base 1 on the fixed frame 2. In addition, the adjustment component 3 can also drive the fixed frame 2 to move along the X direction of the base 1, so as to adapt to PCB circuit boards of different sizes. The adjustment component 3 is also connected to the fixture component 4 so that it can move synchronously with the adjustment component 3 and press the PCB circuit board.

[0038] Specifically, the fixed frame 2 includes a first frame 21 and a second frame 22. The first frame 21 and the second frame 22 are respectively provided with mounting grooves 23. The mounting grooves 23 are suitable for forming the mounting position 24 in pairs, or each mounting groove 23 independently forms the mounting position 24. The first frame 21 and the second frame 22 are both provided with adjustment components 3. The adjustment components 3 respectively provided on the first frame 21 and the second frame 22 can work independently or simultaneously. The adjustment component 3 includes a driving motor 31, a threaded rod 32, a movable block 33 and a slide rail 37. The output end of the driving motor 31 is connected to the threaded rod 32. The movable block 33 is arranged on the threaded rod 32 and the slide rail 37. The slide rail 37 and the threaded rod 32 are arranged parallel to the Y direction of the base 1. When the threaded rod 32 is driven to rotate by the driving motor 31, the movable block 32 arranged thereon is suitable for moving within the range defined by the threaded rod 32 and the slide rail 37, and the movable block 33 is connected to the clamp component 4, thereby driving the clamp component 4 to move in the Y direction to adapt to the size of the PCB circuit board in the Y direction.

[0039] More specifically, the adjustment assembly 3 further includes a piston rod 34 and a hydraulic cylinder 35, the piston rod 34 and the hydraulic cylinder 35 are respectively arranged corresponding to the first frame 21 and the second frame 22, and one end of the piston rod 34 is connected to the output end of the hydraulic cylinder 35, and the other end of the piston rod 34 is connected to the corresponding first frame 21 or second frame 22, so that the piston rod 34 can be driven by the hydraulic cylinder 35 to push the first frame 21 and the second frame 22 to move along the X direction of the base 1. Therefore, by adjusting the first frame 21 and the second frame 22 in the X direction to adapt to the PCB circuit board with a narrow width, the applicable scope of the clamp is expanded, and the versatility and flexibility of the clamp are improved to be applicable to PCB circuit boards of different sizes.

[0040] In addition, the adjustment assembly 3 also includes a frame support plate 36, which is provided with a plurality of fixing holes, and the piston rod 34 is suitable for passing through the corresponding fixing holes to adjust the position of the piston rod 34 on the fixed frame 2. The inner surface of the hydraulic cylinder 35 is fixedly installed with the frame support plate 36 to support the weight of the entire clamp, and the base 1 provides a position for the installation of the entire clamp and shares the weight of the clamp itself.

[0041] See also Figure 3 to Figure 4 The fixture assembly 4 includes a mounting bracket 41, a bracket guide rail 42 and a bracket slide 43.

Among them, a long hole is opened at the upper end of the fixed frame 2 to provide a certain range of movement and installation position for the movement of the fixture assembly 4 thereon. The setting of the bracket guide rail 42 can prevent the electric cylinder 44 and the pressure plate 45 arranged on the mounting bracket 41 from being offset during the movement process, thereby ensuring the stability of both during the movement process.

[0042] Specifically, the clamp assembly 4 includes an electric cylinder 44 and a pressing plate 45. The electric cylinder 44 is arranged on the mounting bracket 41. The pressing plate 45 is connected to the output end of the electric cylinder 44. The electric cylinder 44 is suitable for driving the pressing plate 45 to move in the vertical direction to hold the PCB or to separate from the PCB. That is, the pressing plate 45 is driven downward by the electric cylinder 44 so that the pressing plate 45 can contact and hold the upper surface of the PCB, thereby fixing the PCB on the mounting position 24 of the fixed frame 2 by using the pressing plate 45.

[0043] More specifically, a buffer foam 25 is also provided on the mounting position 24, and the PCB circuit board is placed on the buffer foam 25, so as to disperse the pressure from the pressing plate 45 when the pressing plate 45 presses the PCB circuit board, and provide buffering, thereby preventing the pressing plate 45 from breaking the contact part of the PCB circuit board with the outer surface of the fixing frame 2 due to excessive pressure, thereby causing damage to the PCB circuit board. In addition, the bracket slide groove 43 is attached to the lower surface of the mounting bracket 41, so as to bear the weight of the mounting bracket 41, and will not hinder the forward and backward sliding of the mounting bracket 41.

The interior of the device box 5 contains a power supply, a battery, and other components for accommodating the normal operation of the fixture. The device box 5 is also provided with a power interface 52, which allows the external power line to be connected to the interior of the device, so that the external power supply device can be connected to the fixture, thereby ensuring the normal power supply of the device. The power switch 53 provided on the device box 5 controls the power on and off of the fixture itself, thereby disconnecting the power supply to ensure the safety of the fixture when not in use. At the same time, the device box 5 and the control terminal 6 are connected by a data line 54 to ensure the data and power transmission between the device box 5 and the control terminal 6, and the control terminal 6 can facilitate the staff to view and control the status and parameters of the fixture.
