Description

Technical Field

[0001] This utility model relates to the field of fixture technology, and in particular to a fixture for fixing sheet-like electronic components. Background Technology

[0002] "Surface mount electronic components" is not a standard academic term, but rather a descriptive term commonly used in the fields of electronics manufacturing, procurement, and repair. It mainly refers to electronic components, assemblies, or structural parts that are flat and thin in physical form. Surface mount electronic component fixtures are customized tools or devices specifically used to position, support, and fix surface mount electronic components during production, assembly, testing, or soldering processes.

[0003] In the existing technology, most of the fixtures for fixing sheet electronic components can only be used for sheet electronic components of one size. When the size of the sheet electronic component changes, the fixture needs to be changed, which is quite troublesome. Therefore, we propose a fixture for fixing sheet electronic components to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that most fixing fixtures for sheet electronic components can only be used for sheet electronic components of one size. When the size of the sheet electronic component changes, the fixing fixture needs to be changed, which is quite troublesome. Therefore, a fixing fixture for sheet electronic components is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A fixture for securing sheet-like electronic components, comprising:

[0007] The base and the first and second support plates fixedly installed on the top of the base;

[0008] A rotating seat is rotatably mounted on the first support plate, and a placement seat is fixedly mounted on one side of the rotating seat;

[0009] Four positioning frames of different sizes are fixedly installed on the top, bottom, front and rear sides of the placement base, respectively;

[0010] Four rectangular cavities are provided on the placement base, and multiple suction holes are opened on one inner wall of each of the four rectangular cavities;

[0011] The mounting slot is located on one side of the placement seat. A hollow seat is installed in the mounting slot. Four suction tubes are fixedly connected to the hollow seat. One end of each of the four suction tubes is fixedly connected to one of the four rectangular cavities. Each of the four suction tubes is equipped with a solenoid valve.

[0012] The negative pressure device is installed on the bottom inner wall of the installation groove. One end of the negative pressure device is connected to the connecting pipe, and the other end of the connecting pipe is fixedly connected to the hollow base.

[0013] Multiple locking slots are located on one side of the placement base;

[0014] The locking mechanism, located on the second support plate, is used to fix the placement seat in conjunction with the locking groove.

[0015] Preferably, the locking mechanism includes a locking plate, one side of which is engaged with a corresponding locking groove, and a push-pull plate is fixedly installed on the other side of the locking plate.

[0016] Preferably, the second support plate has a rectangular sliding hole, and the locking plate is slidably installed in the rectangular sliding hole.

[0017] Preferably, the top of the second support plate is threaded with a locking bolt, and the top of the locking plate is provided with a threaded groove, and the locking bolt is threadedly connected to the threaded groove.

[0018] Preferably, the second support plate is provided with a circular hole.

[0019] Preferably, the first support plate has a rotating hole, and a bearing is fixedly installed in the rotating hole. The outer side of the rotating seat is fixedly connected to the inner ring of the bearing.

[0020] Preferably, the negative pressure device is a negative pressure fan or a negative pressure generator.

[0021] Preferably, notches are provided on both sides of the four positioning frames.

[0022] Compared with the prior art, the advantages of this utility model are:

[0023] Achieving multi-size compatibility and improving equipment versatility: The tooling uses four positioning frames of different sizes fixedly installed on the top, bottom, front and rear sides of the placement base, and is designed with a rotatable structure. This allows the tooling to be switched to the matching positioning frame simply by rotating the placement base when the size of the sheet electronic component changes, without having to replace the entire tooling. This significantly improves the applicability and work efficiency of the tooling.

[0024] Utilizing negative pressure adsorption for secure fixing, this method protects components and offers high adaptability: Through the coordination of a negative pressure device, suction tube, solenoid valve, and suction port, sheet-like electronic components are fixed using the principle of negative pressure adsorption. This non-mechanical clamping method avoids scratches or deformation that may be caused by physical contact, making it particularly suitable for thin, fragile electronic components. It also provides uniform adsorption and fixation, adapting to sheet-like components of different shapes and materials.

[0025] Compact structure and easy operation enhance positioning accuracy and stability: The tooling integrates a locking mechanism (locking plate, locking bolts, etc.) and rotation adjustment function, with a reasonable structural design. Operators can easily switch sizes and fix the fixture with simple push-pull and rotation actions. The locking bolts ensure that the placement seat remains stable during operation, effectively improving the positioning accuracy of the parts and the stability of the processing / testing process.

[0026] Facilitates the handling and observation of accessories, optimizing the user experience: The notch design on both sides of the positioning frame makes it easy to access and handle sheet-like electronic accessories from the side, avoiding operational inconvenience caused by space constraints.

[0032] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this embodiment, and not all embodiments.

[0033] Example 1

[0034] Reference Figures 1-4 A fixture for securing sheet-like electronic components, comprising:

[0035] Base 1 and a first support plate 2 and a second support plate 3 fixedly installed on the top of base 1;

[0036] The rotating seat 5 is rotatably mounted on the first support plate 2, and a placement seat 6 is fixedly mounted on one side of the rotating seat 5;

[0037] Four positioning frames 7 of different sizes are fixedly installed on the top, bottom, front and rear sides of the placement base 6, respectively;

[0038] Four rectangular cavities are provided on the placement base 6, and multiple suction holes 9 are opened on one inner wall of each of the four rectangular cavities; the four rectangular cavities are independent and sealed cavities, and each cavity is dedicated to serving a specific positioning frame 7.

[0039] The mounting slot 10 is located on one side of the placement seat 6. A hollow seat 11 is installed in the mounting slot 10. Four suction tubes 12 are fixedly connected to the hollow seat 11. One end of each of the four suction tubes 12 is fixedly connected to a rectangular cavity. Each of the four suction tubes 12 is equipped with a solenoid valve 13.

[0040] The negative pressure device 15 is installed on the bottom inner wall of the mounting groove 10. One end of the negative pressure device 15 is connected to the connecting pipe 14, and the other end of the connecting pipe 14 is fixedly connected to the hollow base 11.

[0041] Multiple locking slots 16 are provided on one side of the placement seat 6; the locking slots are regularly arranged on a circle with the axis of the rotating seat 5 as the center.

[0042] A locking mechanism is provided on the second support plate 3, which is used to fix the placement seat 6 in conjunction with the locking groove 16.

[0043] In this embodiment, the locking mechanism includes a locking plate 18, one side of which is engaged with a corresponding locking groove 16, and a push-pull plate 19 is fixedly installed on the other side of the locking plate 18.

[0044] In this embodiment, a rectangular sliding hole 17 is provided on the second support plate 3, and the locking plate 18 is slidably installed in the rectangular sliding hole 17.

[0045] In this embodiment, a locking bolt 20 is threadedly installed on the top of the second support plate 3, and a threaded groove is opened on the top of the locking plate 18, with the locking bolt 20 threadedly connected to the threaded groove.

[0046] In this embodiment, the second support plate 3 is provided with a circular hole 21, which facilitates observation of the working status of the negative pressure equipment.

[0047] In this embodiment, a rotating hole 4 is provided on the first support plate 2, and a bearing is fixedly installed in the rotating hole 4. The outer side of the rotating seat 5 is fixedly connected to the inner ring of the bearing.

[0048] In this embodiment, the negative pressure device 15 is a negative pressure fan or a negative pressure generator.

[0049] In this embodiment, notches 8 are provided on both sides of the four positioning frames 7. The notches 8 make it convenient to contact the sheet-like electronic components from the side, and thus make it convenient to remove the sheet-like electronic components from the inside of the positioning frames 7.

[0050] In this embodiment, during use, the sheet-like electronic component to be processed is placed inside the positioning frame 7 at the top of the placement base 6. The uppermost solenoid valve 13 is opened, and the negative pressure device 15 is activated. Air is drawn from the hollow base 11 through the connecting pipe 14. The hollow base 11 draws air from the rectangular cavity through the suction pipe 12 connected to the opened solenoid valve 13, creating a negative pressure inside the rectangular cavity. This negative pressure is then used to suction the sheet-like electronic component through multiple suction holes 9 connected to the rectangular cavity, thus achieving the positioning of the sheet-like electronic component. When the size of the sheet-like electronic component changes, the locking bolt 20 is loosened, causing the locking bolt 20 to disengage. Release the locking plate 18 from the threaded groove, pull the push-pull plate 19 away from the second support plate 3, and the push-pull plate 19 will cause the locking plate 18 to disengage from the locking groove 16, releasing the fixing of the placement seat 6. Rotate the placement seat 6 to rotate the positioning frame 7, which matches the size of the new sheet electronic component to be processed, to the top. Then, insert the locking plate 18 into the corresponding locking groove 16, thread the locking bolt 20 into the threaded groove, and fix the locking plate 18. Then, close the previous solenoid valve 13 and open the new solenoid valve 13 located above, thereby adapting to sheet electronic components of different sizes.

[0051] Example 2

[0052] The difference from Embodiment 1 is that each positioning frame 7 has an independent rectangular cavity corresponding to that positioning frame 7 located below the area enclosed by the positioning frame 7 (i.e., on the corresponding surface of the placement seat 6). This design allows for independent control of which positioning frame 7's components are adsorbed and fixed by controlling different solenoid valves 13.
