Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figures 1 to 5 , the utility model provides a technical solution:

[0028] A positioning fixture for a flexible circuit board comprises a base plate 1, support feet 11 are fixedly installed at four corners of the bottom of the base plate 1, positioning holes 12 are provided at four corners of the top of the base plate 1, a first positioning groove 13 is provided at the top of the base plate 1, buckle plates 14 are movably installed on the left and right sides of the base plate 1, a first positioning component 2 is arranged inside the first positioning groove 13, the first positioning component 2 comprises a first air bag 21, the first air bag 21 is fixedly installed inside the first positioning groove 13, a first sponge pad 22 is fixedly installed on the surface of the first air bag 21, a micro air pump 23 is fixedly installed on the left side of the front end of the base plate 1, the micro air pump 23 is connected to the first air bag 21, a first top-moving air valve 26 is fixedly installed on the right side of the top of the base plate 1, and the first top-moving air valve 26 is connected to the first air bag 21.

[0029] A first clamping plate 3 is movably installed on the top of the base plate 1, and first limiting columns 31 are fixedly installed at the four corners of the bottom of the first clamping plate 3. Limiting holes 32 are provided at the four corners of the top of the first clamping plate 3. A second positioning groove 33 is provided inside the first clamping plate 3, and a second positioning component 4 is provided inside the first limiting column 31. The second positioning component 4 includes a second airbag 41, and the second airbag 41 is fixedly installed inside the second positioning groove 33. A second sponge pad 42 is fixedly installed on the upper and lower end surfaces of the second airbag 41. An air injection port 43 is provided on the right side of the bottom of the first clamping plate 3, and a second top-moving air valve 44 is fixedly installed on the right side of the top of the first clamping plate 3.

[0030] The gas injection port 43 and the second push-acting gas valve 44 are both connected to the second airbag 41 . After the first clamping plate 3 and the bottom plate 1 are installed, the first push-acting gas valve 26 can be inserted into the gas injection port 43 , and the first limiting column 31 can be inserted into the positioning hole 12 .

[0031] The second sponge pad 42 installed on the top of the second airbag 41 is located inside the second positioning groove 33, and the second sponge pad 42 installed on the bottom of the second airbag 41 extends out of the bottom of the first plywood 3. After the first plywood 3 and the bottom plate 1 are installed, the second sponge pad 42 at the bottom of the second airbag 41 is located in the first positioning groove 13. The first plywood 3 and the second plywood 5 have the same structure and can be spliced ​​up and down. The number of first plywood 3 and second plywood 5 can be determined according to actual usage requirements. A top plate 6 is movably installed on the top of the second plywood 5, and second limiting columns 61 are fixedly installed at the four corners of the bottom of the top plate 6. Buckle grooves 62 that match the buckle plate 14 are provided on the left and right sides of the top of the top plate 6.

[0032] By adopting the above technical solution, when in use, first place a group of flexible circuit boards in the first positioning groove 13 of the bottom plate 1, the flexible circuit boards are located on the surface of the first sponge pad 22, and then place the first clamping plate 3 on the top of the bottom plate 1, and splice through the first limiting column 31 at the bottom of the first clamping plate 3 and the positioning hole 12 at the top of the bottom plate 1, after placing the first clamping plate 3, place the second group of flexible circuit boards in the second positioning groove 33, the flexible circuit boards are located on the surface of the second sponge pad 42, and then place the second clamping plate 5 on the first clamping plate 3. The top of the board 3 is spliced ​​through the limiting hole 32 on the top of the first splint 3 and the first limiting column 31 at the bottom of the second splint 5. After the second splint 5 is placed, the third group of flexible circuit boards is placed inside the second splint 5. Finally, the top plate 6 is covered on the second splint 5 and spliced ​​and positioned through the limiting hole 32 on the top of the second splint 5 and the second limiting column 61 at the bottom of the top plate 6. After the top plate 6 is placed, it is necessary to press the top plate 6 down with a little force to buckle it into the buckle groove 62 at the top of the top plate 6 through the buckle plates 14 on both sides to complete the splicing of the device.

[0033] The surface of the first sponge pad 22 is in a flat state. During use, as long as the flexible circuit board can be placed in the first positioning groove 13 or the second positioning groove 33, the device can be used for positioning and clamping. After the first splint 3 and the base plate 1 are spliced ​​and installed, the second sponge pad 42 extending from the bottom of the first splint 3 is inserted into the first positioning groove 13, thereby clamping the flexible circuit board between the first sponge pad 22 and the second sponge pad 42. After the first splint 3 and the base plate 1 are spliced, the first top-moving air valve 26 will also be inserted into the gas injection port 43. The first top-moving air valve 26 is inserted into the gas injection port 43 and because the device has been closed by the buckle plate 14, the first top-moving air valve 26 is in a compressed state at this time, and the first top-moving air valve 26 in the compressed state is in a deflated state. Therefore, gas can be introduced into the second airbag 41 through the gas injection port 43 spliced ​​with the first top-moving air valve 26, so that The first airbag 21 is inflated with a micro air pump 23. During the inflation process, the first airbag 21 also injects gas into the second airbag 41 through the first push-type air valve 26 and the air injection port 43. The clamp above the first splint 3 is also inflated in this way. When the first airbag 21 and the second airbag 41 are filled with air, they expand and compress the space between them. Because the surface of the first airbag 21 is provided with a first sponge pad 22, and the surface of the second airbag 41 is provided with a second sponge pad 42, the flexible circuit board between the two will not be damaged, further improving the positioning and clamping ability of the flexible circuit board and protecting it. The device first positions and clamps the flexible circuit board by splicing the bottom plate 1 and the first splint 3, and then positions and clamps the flexible circuit board again by inflating the first airbag 21 and the second airbag 41, and protects the flexible circuit board.

[0034] Specifically, Figures 2 to 5 As shown, a first exhaust groove 24 is provided at the front end of the base plate 1 and located on the right side of the micro air pump 23. A first sealing slider 25 is movably installed inside the first exhaust groove 24. An exhaust hole connected to the first airbag 21 is provided inside the first exhaust groove 24 and can be blocked by the first sealing slider 25.

[0035] A second exhaust groove 45 is provided at the front end of the first clamping plate 3, and a second sealing slider 46 is movably installed inside the second exhaust groove 45. An exhaust hole connected to the second airbag 41 is provided inside the second exhaust groove 45 and can be blocked by the second sealing slider 46. The second airbag 41 and the first airbag 21 are both convex when filled with gas.

[0036] By adopting the above technical scheme, when taking the flexible circuit board clamped by the bottom plate 1, the first clamp 3, the second clamp 5 and other clamps, first open the buckle plates 14 on both sides of the top plate 6. At this time, since the first airbag 21 and the second airbag 41 are in an expanded state, when the restriction on the top plate 6 is released, the bottom plate 1, the first clamp 3, and the second clamp 5 will all pop open, which is convenient for separating the bottom plate 1, the first clamp 3, and the second clamp 5. Since the first airbag 21 is in an expanded state, its top will arch upward and protrude from the first positioning groove 13 after the restriction is released. Therefore, the flexible circuit board on the surface of the first sponge pad 22 will also be pushed out of the first positioning groove 13 by the first airbag 21, which is convenient for taking out the flexible circuit board in the first positioning groove 13. The process of taking out the flexible circuit board in the first clamp 3 and the second clamp 5 is the same as above. After taking out the flexible circuit board, slide the first sealing slider 25 to the left so that the first sealing slider 25 no longer blocks the exhaust hole connected between the first exhaust groove 24 and the first airbag 21, exhaust the air in the first airbag 21, and retract the top of the first airbag 21 into the first positioning groove 13, so as to facilitate the positioning and clamping of the flexible circuit board next time. The first and second clamps are operated in the same way as above, and the internal airbags need to be exhausted after taking out the flexible circuit board. Through the above structural design, the flexible circuit board can be easily taken out of the device after the positioning and clamping work of the flexible circuit board is completed, and the gas in the capsule inside the clamp can be quickly exhausted by sliding the first sealing slider 25, so as to facilitate the next use, so that the device can be easily recycled, and the practicality of the device is improved.

[0037] Working principle: When in use, first place the flexible circuit board in the first positioning groove 13 of the bottom plate 1, then place the first clamping plate 3 on the top of the bottom plate 1, and splice through the positioning hole 12 and the first limiting column 31. After splicing, place the second set of flexible circuit boards in the second positioning groove 33, repeat the above operation until the top plate 6 is spliced ​​at the top, and then close it through the buckle plates 14 on the left and right sides of the bottom plate 1 and the buckle groove 62 on the top of the top plate 6. When closing, press the top plate 6 downward so that the first top-moving air valve 26 and the second top-moving air valve 44 can be inserted into the gas injection port 43, so that the gas in the fixture can circulate. After the device is installed, turn on the micro air pump 23 to inflate the first airbag 21. During the inflation process, the first airbag 21 will simultaneously inflate the second airbag 41 through the first push-type air valve 26 and the air injection port 43. After the inflation is completed, the first airbag 21 and the second airbag 41 are both in an expanded state, and the flexible circuit board is clamped again by the first sponge pad 22 and the second sponge pad 42 on their surfaces. After the clamp is used and the flexible circuit board is taken out, the first sealing slider 25 needs to be slid so that the first sealing slider 25 no longer blocks the exhaust hole connecting the first exhaust groove 24 and the first airbag 21, so as to exhaust the bag body for the next use.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
