DETAILED DESCRIPTION

[0023] See also Figure 1-6 The utility model provides a technical solution: a clamping mechanism for circuit board detection, including a body 1 and an auxiliary device 8, a bracket 2 is arranged on the surface of the body 1, a cylinder 3 is arranged above the bracket 2, a pressure head 4 is fixedly connected to the output end of the cylinder 3, a plurality of upper contacts 7 are arranged on the lower surface of the pressure head 4, a treatment body 5 is arranged above the body 1, a plurality of lower contacts 6 are fixedly connected to the upper part of the body 1, and the auxiliary device 8 is arranged on the surface of the upper contact 7.

[0024] The specific settings and functions of the auxiliary device 8 and the maintenance device 9 will be described in detail below.

[0025] Specifically, the auxiliary device 8 includes a ring 82, which is slidably connected to the surface of the upper contact 7. A contact sleeve 81 is provided below the ring 82. A ring piece 86 is slidably connected to the inner wall of the contact sleeve 81. A spring 88 is fixedly connected to the side of the ring piece 86 corresponding to the inner wall of the contact sleeve 81.

[0026] In this embodiment, when the pressure head 4 drives the upper contact 7 to press down, the upper contact 7 drives the contact sleeve 81 to move. When the contact sleeve 81 contacts the detection point of the circuit board, the upper contact 7 continues to move, and the upper contact 7 pushes the ring piece 86. The spring 88 is stressed, so that the contact sleeve 81 is pressed tightly against the detection point on the surface of the circuit board, thereby improving the measurement accuracy.

[0027] Specifically, a plurality of hangers 84 are fixedly connected to the surface of the contact sleeve 81, and a card slot is provided on the surface of the ring 82. The hangers 84 are card-engaged with the inner wall of the card slot. By carding the hangers 84 into the card slot on the surface of the ring 82, the contact sleeve 81 can be installed, which is convenient for maintenance and replacement.

[0028] Specifically, three magnetic rings 1 83 are fixedly connected to the inner wall of the sleeve ring 82 , and three magnetic rings 2 85 are fixedly connected to the inner wall of the contact sleeve 81 . The magnetic rings 1 83 and 2 85 are magnetically connected.

[0029] In this embodiment, after the hanging piece 84 is inserted into the slot on the surface of the sleeve ring 82, the contact sleeve 81 is rotated to make the hanging piece 84 abut against the inner wall of the slot, and then the magnetic ring 1 83 and the magnetic ring 2 85 correspond to each other and attract and position each other.

[0030] Specifically, a gasket 87 is fixedly connected to the surface of the ring sheet 86 , and the gasket 87 can protect the upper contact 7 and increase the service life.

[0031] Specifically, a maintenance device 9 is provided on one side of the machine body 1 close to the treatment body 5, and the maintenance device 9 includes a sleeve rod 92 and a pressure ring 93. There are multiple sleeve rods 92, and multiple sleeve rods 92 are fixedly connected to the surface of the machine body 1. Four kits 91 are fixedly connected to the surface of the treatment body 5. The kit 91 is sleeved and connected to the sleeve rod 92. The pressure ring 93 is arranged above the sleeve rod 92. The pressure ring 93 is sleeved and connected to the sleeve rod 92. Two plug blocks 95 are slidably connected to the inner wall of the sleeve ring 82. A slot is provided on the surface of the sleeve rod 92, and the plug block 95 is plugged into the inner wall of the slot. A spring 2 96 is fixedly connected to the side of the plug block 95 corresponding to the inner wall of the pressure ring 93.

[0032] In this embodiment: when the treatment body 5 is installed, the kit 91 is mounted on the sleeve rod 92, and then the pressure ring 93 is mounted in the sleeve rod 92 and pressed on the kit 91, and the spring 96 drives the plug 95 to be inserted into the slot on the surface of the sleeve rod 92, which is convenient for disassembly and subsequent maintenance.

[0033] Specifically, a limiting groove is provided on the surface of the sleeve rod 92, and the pressure ring 93 is plugged into the inner wall of the limiting groove. Inserting the pressure ring 93 into the limiting groove on the surface of the sleeve rod 92 can limit the pressure ring 93 and improve the overall usability.

[0034] Specifically, a rope body 94 is fixedly connected to the surface of the sleeve rod 92 , and the other end of the rope body 94 is fixedly connected to the surface of the pressure ring 93 .

[0035] In this embodiment, the rope body 94 can connect the sleeve rod 92 and the pressure ring 93, which is convenient for use.

[0036] Working principle: When the equipment is used, the circuit board is placed on the treatment body 5, and the cylinder 3 drives the pressure head 4 and the upper contact 7 to move. The upper contact 7 cooperates with the lower contact 6 to fit the detection point of the circuit board for detection. By setting the auxiliary device 8, when the detection is performed, the pressure head 4 drives the upper contact 7 to press down, and the upper contact 7 drives the contact sleeve 81 to move. When the contact sleeve 81 contacts the detection point of the circuit board, the upper contact 7 continues to move, and the upper contact 7 pushes the ring piece 86. The spring 88 is stressed, so that the contact sleeve 81 is in contact with the detection point on the circuit board surface. When replacing the contact sleeve 81, it is only necessary to rotate the contact sleeve 81 so that the hanger 84 loses the restraint on the surface groove of the ring 82, and the contact sleeve 81 can be removed for replacement. By setting the auxiliary device 8, it is convenient for the auxiliary equipment to detect the circuit board, which can effectively reduce the existing detection equipment when detecting the circuit board. Due to the long-term detection of the detection probe, the probe head is easily damaged, resulting in the probe being unable to be tightly pressed against the detection point of the circuit board during the next detection, affecting the detection, thereby improving the overall practicality of the equipment.

[0037] By setting up the maintenance device 9, when maintenance and disassembly are required, the plug block 95 is pushed, the spring 96 is stressed, and the plug block 95 is removed from the slot on the surface of the sleeve rod 92, and the pressure ring 93 is taken out from the sleeve rod 92. The pressure ring 93 loses the restraint on the kit 91, and the kit 91 and the fixture body 5 can be removed from the sleeve rod 92 for maintenance and replacement. This can effectively reduce the existing circuit board detection equipment. When placing the fixture, the fixture is mostly fixed by screws, which makes it inconvenient to disassemble during maintenance, resulting in inconvenience in use.
