[0019] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or a specific connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0020] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0021] like Figure 1-Figure 5 As shown, the utility model proposes a rapid detection device for solder joint height, including a base 1 and a detection component 2. The base 1 is provided with a fixing area 11 on the top end surface, and the fixing area 11 is used to fix the PCB board. The detection component 2 is installed on the top end surface of the base 1. The detection component 2 includes a detection plate 21. The detection plate 21 can be moved to above the fixing area 11 and form a measuring space 210 between the fixing area 11 and the detection plate 21.

[0022] It can be understood that, since the utility model is provided with a detection plate 21, the detection plate 21 can be moved to the top of the fixed area 11, and a measuring space 210 is formed between the fixed area 11, and the height of the measuring space 210 is set to the upper limit height of the welding point. Through the above setting, when the welding point is detected, the PCB board can be fixed in the fixed area 11, so that the welding point to be tested is set upward, and the detection plate 21 can be moved toward the fixed area 11 at this time. If the detection plate 21 can smoothly pass above the fixed area 11, it means that the height of the welding point of the PCB board is within the upper limit. If the detection plate 21 is blocked by the welding point, resulting in it being unable to pass above the fixed area 11, it means that the height of the welding point of the PCB board exceeds the upper limit. Compared with the traditional caliper measurement, the utility model can realize the height detection of the welding point of the PCB board only by moving the detection plate 21, has a simple structure, is convenient to operate, and greatly improves the detection efficiency and detection accuracy.

[0023] Furthermore, in the present embodiment, the detection component 2 also includes a sliding connection portion 22, which is arranged on one side of the fixed area 11 and is detachably connected to the base 1, and the detection plate 21 is slidably connected to the sliding connection portion 22. Specifically, the sliding connection portion 22 is provided with a sliding groove 221 on the side wall, and the detection plate 21 is provided with a connecting groove 211 at the bottom, and the connecting groove 211 forms an opening 212 at the bottom, and a clamping portion 213 is provided at the opening 212, and the clamping portion 213 is used to clamp with the sliding groove 221.

[0024] It can be understood that when the detection plate 21 is connected to the sliding connection part 22, the sliding connection part 22 can be inserted into the connecting groove 211 through the opening 212 at one end of the sliding connection part 22, so as to realize the clamping of the clamping part 213 in the sliding groove 221. Through the above arrangement, the detection plate 21 can slide back and forth relative to the sliding connection part 22 to realize the forward and backward movement of the detection plate 21 above the fixed area 11.

[0025] Furthermore, as a preference, a limiting portion 2211 is also provided in the slide groove 221 , and the weld height rapid detection device further includes a limiting member 3 , which is detachably connected to the base 1 , and the limiting member 3 is provided at one end of the sliding connection portion 22 away from the fixed area 11 .

[0026] It can be understood that when the detection plate 21 moves forward to a certain displacement, the clamping portion will abut against the limiting portion 2211 to limit the detection plate 21 from continuing to move forward and prevent the detection plate 21 from escaping from the front end of the sliding connection portion 22. Similarly, the limiting portion 3 is used to prevent the detection plate 21 from escaping from the rear end of the sliding connection portion 22. Furthermore, in this embodiment, the user can also realize the detection of different welding point heights by replacing the sliding connection portions 22 with different heights.

[0027] Furthermore, in the present embodiment, the detection assembly 2 further includes a push rod 23 , which is connected to the detection plate 21 . The push rod 23 is convenient for a user to hold so as to push the detection plate 21 to move forward and backward.

[0028] Furthermore, a fixing component 111 is also provided on the peripheral side of the fixing area 11, and the fixing component 111 is used to fix the PCB board. Specifically, the fixing component 111 includes a rotating fixing piece 1111, a fixing column 1112 and an elastic piece 1113. The rotating fixing piece 1111 forms a fixing portion 1114 and a rotating portion 1115 at both ends respectively. The rotating portion 1115 is sleeved on the fixing column 1112, and the rotating portion 1115 can rotate relative to the fixing column 1112 to drive the fixing portion 1114 to rotate. The elastic piece 1113 is sleeved on the fixing column 1112, and one end of the elastic piece abuts against the top protrusion of the fixing column 1112, and the other end abuts against the rotating portion 1115.

[0029] Through the above arrangement, when fixing the PCB board, the fixing portion 1114 can be lifted and rotated above the PCB board. At this time, under the action of the elastic member 1113, the fixing portion 1114 will be pressed against the PCB board to fix the PCB board in the fixing area 11.

[0030] The above are one or more implementation methods provided in combination with specific content, and it is not intended that the specific implementation of the utility model is limited to these descriptions. Any method, structure, etc. similar to or identical to the method, structure, etc. of the utility model, or any technical deduction or replacement based on the concept of the utility model, shall be deemed to be within the protection scope of the utility model.
