Description

Technical Field

[0001] This utility model specifically relates to the field of furnace fixture technology, and more specifically to a furnace fixture for preventing materials from falling out of the trough. Background Technology

[0002] In the electronics manufacturing industry, the reflow process is a crucial step in soldering electronic components onto circuit boards. Reflow fixtures, as specialized tooling for supporting and fixing circuit boards, directly impact soldering quality and production efficiency. Traditional reflow fixtures often employ simple slots or pressing structures to secure circuit boards, but these have several shortcomings in actual production: Firstly, circuit boards are prone to displacement during reflow due to equipment vibration and thermal stress, causing materials to detach from the slots. This can result in poor soldering or, in severe cases, damage to components and circuit boards, increasing production costs. Secondly, the pressing structure of traditional fixtures lacks buffering and precise positioning design, making it difficult to adjust the pressing force. Either the pressing is too loose for effective fixation, or too tight, damaging the circuit board or components. Furthermore, the assembly and disassembly processes of some fixtures are cumbersome, hindering rapid changeovers and maintenance, and reducing production flexibility.

[0003] With the increasing integration of electronic components and the growing complexity of circuit board layouts, higher demands are being placed on the stability, precision, and ease of use of reflow oven fixtures. The industry urgently needs a reflow oven fixture that can structurally prevent material from slipping out of the slot, while also providing precise positioning and flexible pressing capabilities. This is crucial to ensuring the reliability of the reflow process, improving welding yield and production efficiency, and meeting the demands of the electronics manufacturing industry for higher precision and efficiency.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-7 In this embodiment of the utility model, a furnace fixture for preventing material from falling out of the trough includes... A fixture base plate 1, on which an anti-disengagement pressing component 3 is fixedly installed; a circuit board 2 is placed between the fixture base plate 1 and the anti-disengagement pressing component 3. The fixture base plate 1 includes a base plate body 11. The upper inner side of the base plate body 11 is provided with a circuit board positioning area 12, and two positioning holes 13 are provided on both the left and right sides of the circuit board positioning area 12. The upper front and rear sides of the base plate body 11 are respectively provided with two connecting posts 14 and one connecting post 14. The upper ends of the multiple connecting posts 14 are respectively connected to the mounting holes provided on the pressing plate 31 and the protective cover 35.

[0022] By adopting the above technical solutions, the cooperation between the positioning pin 34 and the fixing hole, the docking between the connecting post 14 and the mounting hole, and the design of the circuit board positioning area 12, the precise positioning of the circuit board 2, the fixture base plate 1 and the anti-detachment pressing component 3 is realized, which simplifies the assembly process of the fixture, greatly improves the assembly efficiency, and ensures the consistency of position in each assembly, laying the foundation for stable welding quality.

[0023] In this embodiment, the base plate body 11 has symmetrically arranged rotating grooves 15 inside, which are respectively located on the left and right sides of the circuit board positioning area 12; bearings 16 are installed inside the rotating grooves 15. The inner side of the bearing 16 is connected to the rotating column 17, and the upper end of the rotating column 17 is fixedly connected to the anti-detachment seat 18. The anti-detachment seat 18 is arranged in an inverted L shape, and the upper end of the anti-detachment seat 18 is provided with a threaded hole. The threaded hole at the upper end of the anti-detachment seat 18 is threadedly connected to the anti-detachment bolt 19, and the lower end of the anti-detachment bolt 19 is provided with a clamping pad 110, which is connected to the upper surface of the protective cover 35.

[0024] By adopting the above technical solution, the setting of bearing 16 makes the rotation of rotating column 17 smoother and less wear-prone. The inverted L-shaped structure of anti-detachment seat 18 and the threaded connection of anti-detachment bolt 19 ensure the stability of anti-detachment structure. The lower end of anti-detachment bolt 19 is fixedly installed on the upper surface of pressure pad 110 and protective cover 35, which greatly improves the anti-detachment and stability of jig material.

[0025] In this embodiment, the lower end of the protective cover 35 is connected to the pressing plate 31, and two buffer rubber rings 33 are provided on both the left and right sides of the upper surface of the pressing plate 31. The upper surface of the buffer rubber rings 33 is connected to the lower surface of the protective cover 35. The pressing plate 31 is provided with positioning pins 34 at each of its four corners. The lower end of the positioning pins 34 is connected to the fixing holes at the four corners of the upper end of the base plate body 11. The pressing plate 31 is provided with two pressing adjustment screws 32 on both the left and right sides. The lower end of the pressing adjustment screws 32 is connected to the upper surface of the positioning hole 13.

[0026] By adopting the above technical solution, the pressing adjustment screw 32 can flexibly adjust the pressing force according to the thickness of the circuit board and the layout of the components. The elastic buffering effect of the buffer ring 33 avoids damage to the circuit board and components caused by excessive pressing, so that the fixture can be adapted to different types and thicknesses of circuit boards, and improves the versatility and flexibility of the fixture.

[0027] The working principle of this utility model is as follows: the circuit board 2 is placed in the circuit board positioning area 12 of the fixture base plate 1, and the initial positioning of the circuit board 2 is achieved by using the shape and size of the circuit board positioning area 12; the pressing plate 31 is precisely connected to the fixing holes of the base plate body 11 through the positioning pins 34 at the four corners, so as to ensure the relative position accuracy between the pressing plate 31 and the base plate body 11. The protective cover 35 is connected to the base plate body 11 via the connecting column 14, forming the upper structure of the pressing assembly; the rotating column 17 can rotate flexibly under the support of the bearing 16, driving the inverted L-shaped anti-detachment seat 18 to rotate above the protective cover 35, and applying downward pressing force to the protective cover 35 through the anti-detachment bolt 19 and the pressing pad 110, thus assisting in preventing the pressing assembly from shifting from above; by turning the pressing adjustment screw 32, the pressing force of the pressing plate 31 on the circuit board 2 can be adjusted, and at the same time, the buffer rubber ring 33 plays an elastic buffering role between the protective cover 35 and the pressing plate 31 to avoid hard contact damage; During the reflow process, the pressing plate 31 applies stable pressure to the circuit board 2 from above, and the anti-detachment seat 18 and anti-detachment bolt 19 provide auxiliary limiting from above, completely eliminating the risk of the circuit board 2 falling out of the slot and ensuring the positional stability of the circuit board 2 during the reflow process. The fit between the positioning pin 34 and the fixing hole, the docking between the connecting post 14 and the mounting hole, and the design of the circuit board positioning area 12 enable precise positioning of the circuit board 2, the fixture base plate 1 and the anti-dislodgement pressing component 3, simplify the assembly process of the fixture, greatly improve the assembly efficiency, and ensure the consistency of position in each assembly, laying the foundation for stable welding quality. The pressing adjustment screw 32 can flexibly adjust the pressing force according to the thickness of the circuit board and the layout of the components. The elastic buffering effect of the buffer ring 33 avoids damage to the circuit board and components due to excessive pressing, so that the fixture can be adapted to different types and thicknesses of circuit boards, improving the versatility and flexibility of the fixture. The bearing 16 makes the rotation of the rotating column 17 smoother and less wear-prone. The inverted L-shaped structure of the anti-detachment seat 18 and the threaded connection of the anti-detachment bolt 19 ensure the stability of the anti-detachment structure. The lower end of the anti-detachment bolt 19 is fixedly installed on the upper surface of the pressure pad 110 and the protective cover 35, which greatly improves the anti-detachment and stability of the fixture material.
