[0030] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below with reference to the accompanying drawings.

[0031] like Figure 1As shown, in this embodiment, the circuit board 1 is provided with a plurality of positioning holes 101. In actual situations, the positioning holes 101 are formed during the preparation process of the circuit board 1, or they may be reserved spaces formed during the preparation process of the circuit board 1 and formed by a drilling process. The formed positioning holes 101 may be used to install a fixing device.

[0032] This embodiment also includes a connecting part 2, a plurality of supporting parts 3 and a clamping part 4. The connecting part 2 is provided with a first adjusting component 201, and one end of the connecting part 2 is respectively connected to the corresponding supporting parts 3, and the plurality of supporting parts 3 are respectively provided with corresponding clamping parts 4, wherein the first adjusting component 201 can adjust the connecting part 2, drive the connecting part 2 to move, thereby drive the plurality of supporting parts 3 to move, so that the plurality of supporting parts 3 correspond to the positioning holes 101 respectively, and pass through or are fixed on the positioning holes 101, and then the chip is placed in the clamping part 4, and the operator can solder the chip to the test board using only a hot air gun.

[0033] like Figure 1 As shown, the support part 3 includes a main body and a column, one end of the main body is connected to the connecting part 2, and the other end of the main body is provided with a column, the diameter of the column corresponds to the diameter of the positioning hole 101, and the column is inserted into the positioning hole 101 to form a support between the column and the positioning hole 101. When several support parts 3 are respectively inserted into the corresponding positioning holes 101, the several support parts 3 and the connecting part 2 are vertically fixed in the horizontal direction to prevent the connecting part 2 and the several support parts 3 from excessively tilting or tipping over, so that the several clamping parts 4 can stably clamp the chip.

[0034] like Figure 2 As shown, the connecting part 2 includes a movable part 202, a plurality of connecting parts 2 and a first adjusting component 201. The movable part 202 is a retractable sleeve structure. The plurality of connecting parts 2 are respectively connected to the movable part 202. The first adjusting component 201 can evenly adjust the retraction of the movable part 202 to ensure that the plurality of clamping parts 4 can limit the chip.

[0035] In one example, reference Figure 2 As shown, the connecting part 2 includes a movable part 202, a first connecting part 203, and a second connecting part 204. The first connecting part 203 and the second connecting part 204 are respectively connected to the movable part 202. The first adjusting component 201 passes through the first connecting part 203 and the second connecting part 204 respectively. The first connecting part 203 is connected to the first supporting part 301, and the second connecting part 204 is connected to the second supporting part 302. According to the adjustment of the first adjusting component 201, the movable part 202 is driven to extend and retract, and the first supporting part 301 and the second supporting part 302 are driven to move. The ends of the first supporting part 301 and the second supporting part 302 that are not connected to the connecting part 2 are set corresponding to the positioning hole 101, and pass through or are fixed in the positioning hole 101.

[0036] In specific implementation, by adjusting the first adjustment component 201, the movable part 202 can be extended and retracted, and the distance between the first connection part 203 and the second connection part 204 can be adjusted, thereby adjusting the distance between the first support part 301 and the second support part 302 to adapt to positioning holes 101 of different sizes. The chip can be limited by replacing the fixing device, and can adapt to positioning holes 101 of different sizes, effectively reducing production costs.

[0037] Since the positioning hole 101 designed by the manufacturer is of a fixed size, the position of the positioning hole 101 and the chip size may change according to different test conditions. Figure 1 As shown, the bottom of the support part 3 is vertically arranged with the circuit board 1, and the diameter of the bottom of the support part 3 is the same as the aperture of the positioning frame. At this time, after the support part 3 is inserted into the positioning hole 101, it can form support without the support of the operator, which can improve the welding efficiency of the operator. In another specific embodiment, three support parts 3 are provided, which can further improve the stability of the support part 3 and facilitate the operator to place the chip and perform welding operations.

[0038] In one embodiment, a plurality of support portions 3 are respectively provided with a second adjustment component 401 , and the second adjustment component 401 is used to adjust the distance of the clamping portion 4 .

[0039] In this embodiment, if Figure 1 As shown, the second adjustment component 401 is arranged corresponding to the clamping part 4, and the clamping part 4 is fixed or released by adjusting the second adjustment component 401. First, the second adjustment component 401 is adjusted to release the clamping part 4, and then the clamping part 4 is moved to make the clamping part 4 correspond to the chip size, and the second adjustment component 401 is adjusted again to fix the clamping part 4, so that the clamping part 4 can clamp chips of different sizes.

[0040] In one embodiment, the second adjustment component 401 includes a pushing component 402 and a push rod 403 . The push rod 403 is horizontally and vertically arranged on one side of the clamping portion 4 . The pushing component 402 is used to adjust the tightness of the push rod 403 .

[0041] Specifically, Figure 4 As shown, the second adjustment component 401 includes a pushing component 402 and a push rod 403, and the push rod 403 is vertically arranged at the top of the clamping part 4. After adjusting the position of the clamping part 4, after applying force to the pushing component 402, the pushing component 402 can abut against the top of the push rod 403. At this time, the pushing component 402 is fixed to the push rod 403, and the other end of the push rod 403 abuts against the clamping part 4, thereby fixing the clamping part 4. After removing the force applied to the pushing component 402, the pushing component 402 is pushed to move the pushing component 402 away from the push rod 403. At this time, the clamping part 4 is released from being fixed, and the distance of the clamping part 4 can be adjusted again.

[0042] In one embodiment, a chamber 303 is disposed in the support portion 3 , a push rod 403 is disposed in the chamber 303 , and the clamping portion 4 and the pushing assembly 402 pass through the chamber 303 respectively.

[0043] Specifically, Figure 4 As shown, each support part 3 is provided with a chamber 303, and each chamber 303 is provided with a push rod 403, which can move in the chamber 303 to fix or release the clamping part 4. The clamping part 4 and the pushing component 402 pass through the chamber 303, respectively, and the clamping part 4 can move horizontally in the chamber 303 to adjust the distance between the clamping parts 4, so as to clamp chips of different sizes. The pushing component 402 can move in the chamber 303 to abut against the push rod 403 or move away from the push rod 403.

[0044] In one embodiment, when the pushing assembly 402 abuts against the push rod 403 , the push rod 403 abuts against the clamping portion 4 to fix the clamping portion 4 .

[0045] Specifically, if Figure 4 As shown, when the push assembly 402 is pushed, the push assembly 402 will move horizontally in the chamber 303. When the push assembly 402 is pushed to abut against the ejector pin 403, the other end of the ejector pin 403 will abut against the clamping portion 4. At this time, the ejector pin 403, the push assembly 402 and the clamping portion 4 are respectively fixed in the chamber 303 and can clamp the chip. When the push assembly 402 is moved away from the ejector pin 403, the fixation of the ejector pin 403 is released, and the fixation of the ejector pin 403 to the clamping portion 4 is released. At this time, the clamping portion 4 can move in the chamber 303.

[0046] In one embodiment, the pushing assembly 402 includes a body 404 , a fixing portion 405 and a fixing member 406 . The body 404 is connected to the fixing portion 405 . The fixing member 406 is threadedly arranged with the fixing portion 405 and is used to adjust the tightness of the body 404 .

[0047] like Figure 3 and Figure 4 As shown, specifically, each pushing assembly 402 includes a body 404, a fixing portion 405 and a fixing member 406. The body 404 is connected to the fixing portion 405, and can be integrally formed or detachably connected. The fixing portion 405 is provided with a thread on the side facing outward, and the fixing member 406 is provided with a threaded hole corresponding to the thread, which can cooperate with the fixing portion 405 to adjust the tightness of the body 404. In a specific embodiment, the fixing portion 405 is provided with a thread, and the fixing member 406 is a nut, and the fixing and unlocking of the body 404 are achieved by the cooperation between the threaded nut.

[0048] In one embodiment, a first inclined surface 407 is provided on a side of the body 404 facing the top rod 403 , and a second inclined surface 408 corresponding to the first inclined surface 407 is provided on the top rod 403 .

[0049] like Figure 4 As shown, specifically, the body 404 is provided with a first inclined surface 407 on the side facing the push rod 403, and the push rod 403 is provided with a second inclined surface 408 corresponding to the first inclined surface 107. When the pushing assembly 402 is pushed to make the first inclined surface 407 of the body 404 abut against the second inclined surface 408 of the push rod 403, and then the fixing member 406 is tightened, at this time, the body 404 and the push rod 403 can be fixed, and the clamping part 4 is fixed under the action of the push rod 403. When it is necessary to adjust the position of the clamping part 4, the fixing member 405 is rotated to release the fixing of the fixing member 406 to the body 404. Then, the body 404 is moved away from the fixing member 406, so that the first inclined surface 407 is away from the second inclined surface 408 provided on the push rod 403, so as to release the restriction of the push rod 403 on the clamping part 4.

[0050] By abutting and matching between the inclined surfaces, the push rod 403 can be prevented from sliding and displacing, and the clamping part 4 can be better fixed. And by the threaded matching between the body 404 and the fixing member 406. The functions of precise adjustment and stable locking can be realized, and the structure is compact, the space occupied is small, and quick unlocking and locking can be realized, and the operation efficiency is improved, and the second adjustment component 401 is prevented from being set on the clamping part 4, and the second adjustment component 401 is abutted against the circuit board 1, which causes the inconvenience of the operation of the second adjustment component 401. Therefore, the scheme of setting this embodiment can be applicable to the working scene where the space for welding chips is limited and frequent adjustment is required, and the circuit board 1 is avoided from being accidentally touched, which affects the adjustment of the second adjustment component 401.

[0051] In one embodiment, the clamping portion 4 includes a first clamping block 409 and a second clamping block 410 , and an angle β is defined between the first clamping block 409 and the second clamping block 410 , and the angle β corresponds to the corner of the chip.

[0052] like Figure 5 As shown, specifically, an angle β is formed between the first clamping block 409 and the second clamping block 410, and the angle β is set corresponding to the corner of the chip. In a specific embodiment, the corner of the chip is a right angle, and at this time, the angle β is 90° to fit the edge of the chip and stably clamp the chip.

In a specific embodiment, the first clamping block 409 and the second clamping block 410 may be provided with grooves, which can clamp the chip in the grooves, and can clamp the chip more stably to prevent it from falling.

[0054] In one embodiment, the clamping portion 4 is provided with a locking portion 411 and a locking member, the locking portion 411 is provided with threads, the locking member is provided with threaded holes corresponding to the threads, and the locking member transmits with the locking portion to fix or unlock the clamping portion 4 .

In a specific embodiment, the locking portion 411 is transmitted with a locking member, the locking portion 411 is a thread, and the locking member is a nut. After the clamping portion 4 is placed on the supporting portion 3, the clamping portion 4 is fixed or unlocked by rotating the locking member.

[0056] More specifically, the locking member is rotated so that the locking member abuts against the surface of the support portion 3, and at this time, the clamping portion 4 is fixed. The locking member is then rotated in the opposite direction so that the locking member is away from the support portion 3, and at this time, the clamping portion 4 can move horizontally in the support portion 3 to adapt to chips of different specifications.

[0057] In one embodiment, the first adjustment assembly 201 includes an adjustment member 205 and a plurality of mounting members 206 . The mounting members 206 are arranged corresponding to the connecting portion 2 . The adjustment member 205 and the mounting members 206 are provided with a threaded transmission connection to drive the supporting portions 3 to move closer to or farther from each other.

[0058] like Figure 6 As shown, specifically, a plurality of mounting members 206 are respectively arranged corresponding to a plurality of supporting parts 3 and fixed on the corresponding supporting parts 3.

The adjusting member 205 is provided with threads on both sides, and the mounting member 206 is provided with threaded holes corresponding to the threads. When the adjusting member 205 is rotated, the mounting member 206 is displaced under the transmission of the adjusting member 205, driving the supporting parts 3 to move closer to or farther from each other. More specifically, the supporting parts 3 can move closer to or farther from each other by setting the threads in a forward or reverse direction.

[0059] In one embodiment, the support portion 3 is provided with placement holes 207 , and the mounting members 206 are respectively located in the placement holes 207 .

[0060] like Figure 6As shown, specifically, the support portion 3 is respectively provided with placement holes 207 , and placement columns 208 are respectively provided on both sides of the mounting member 206 , and the placement columns 207 respectively penetrate the placement holes 207 to fix the mounting member 206 on the support portion 3 .

[0061] In one embodiment, the circuit board 1 is provided with a positioning area 102 , and the clamping portion 4 is disposed corresponding to the positioning area 102 .

[0062] like Figure 1 As shown, specifically, a positioning area 102 is pre-set on the circuit board 1, and the positioning area 102 can be a positioning frame or a positioning corner. After the support part 3 is placed on the circuit board 1, the clamping part 4 is aligned with the positioning area 102 by adjusting the second adjustment component 401, and then the chip is clamped to improve the positioning efficiency, so that the chip can be quickly aligned with the pad of the circuit board 1.
