Description

Technical Field

[0001] This utility model relates to the technical field of aluminum paste circuit manufacturing equipment, specifically to an aluminum paste circuit manufacturing equipment. Background Technology

[0002] In the aluminum paste circuit fabrication process, tunnel furnace drying equipment is a key piece of equipment for achieving aluminum paste curing and ensuring circuit quality. It uses specific heating or irradiation components (such as UV lamps) to dry and cure the substrate coated with aluminum paste, ensuring stable aluminum paste circuit formation.

[0003] In the prior art, the patent publication number CN218906033U, "An ultraviolet curing tunnel oven drying equipment", uses a UV lamp as a curing source, wherein the UV lamp is connected to the lamp frame by a double plum nut, and the plum nut is located in the arc-shaped groove of the lamp frame.

[0004] During actual production debugging or maintenance, if it is necessary to adjust the position of the UV lamp to adapt to different substrates and optimize the curing effect, it is necessary to manually loosen the nut on both sides of the lamp frame to release the lamp from its fixation before sliding it for adjustment. This operation requires manual operation of multiple nuts, which is laborious and tedious. It not only increases the labor intensity of workers, but also affects production efficiency due to the time-consuming operation. It is difficult to flexibly and quickly respond to the needs of lamp position adjustment in production, thus limiting the process adaptability and production flexibility of the equipment in aluminum paste circuit fabrication. Utility Model Content

[0005] To solve the above-mentioned technical problems, an aluminum paste circuit manufacturing equipment is provided, which solves the problems existing in the background technology.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an aluminum paste circuit manufacturing equipment, including a belt conveyor, a curing box mounted on the belt conveyor, and a lamp frame mounted inside the curing box. A UV lamp tube is movably mounted on the inner side of the lamp frame. Arc-shaped sliding slits are provided on both sides of the lamp frame. Sliding columns are fixed at both ends of the UV lamp tube. The two sliding columns slide in the two sliding slits respectively. A positioning mechanism for conveniently locking the UV lamp tube is provided on the outer side of the lamp frame.

[0007] The positioning mechanism includes a swing frame in the shape of an inverted U and fixed to the top of the lamp frame, and an arc-shaped toothed plate fixed to the side wall of the lamp frame. A telescopic locking device is provided between the swing frame and the arc-shaped toothed plate. The top of the swing frame is provided with a driving part that cooperates with the telescopic locking device. The two sliding columns are respectively fixed to the inner walls of the two sides of the swing frame. The curvature of the arc-shaped toothed plate is adapted to the curvature of the sliding joint.

[0008] Preferably, the telescopic clip includes a slide and two pins respectively fixed to both ends of one side of the slide, with the ends of the pins inserted between two adjacent teeth of the arc-shaped toothed plate.

[0009] Preferably, an air chamber is provided transversely in the inner wall of the swing frame, and a piston rod is slidably disposed in the air chamber. One end of the piston rod extends out of the swing frame and is fixedly connected to the other side of the sliding plate.

[0010] Preferably, the driving unit includes a drive box fixed in the inner wall of the swing frame, a piston plate that rises and falls in the inner side of the drive box, and an air pipe fixedly connected to the bottom of the side wall of the drive box, with the end of the air pipe penetrating into the air chamber.

[0011] Preferably, a screw is threaded through the middle of the piston plate, and the top end of the screw rotates out of the drive box.

[0012] Compared with existing technologies, the advantages of this invention are as follows: By using a positioning mechanism, it differs from the cumbersome method of manually loosening and tightening the nut to adjust the UV lamp tube in existing technologies. This positioning mechanism, through the adaptation of the swing frame, arc-shaped toothed plate, and telescopic locking device, allows for quick locking or unlocking of the UV lamp tube position simply by operating the telescopic locking device via the drive unit. Workers no longer need to manually operate the nuts at both ends of the UV lamp tube one by one, significantly reducing operational intensity and improving the convenience of adjusting the angle and spacing of the UV lamp tube, thus meeting the needs of frequent adjustment and curing parameter adjustments in aluminum paste circuit fabrication.

[0019] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0020] Reference Figure 1-4 As shown, an aluminum paste circuit fabrication equipment includes a belt conveyor 1, a curing box 2 mounted on the belt conveyor 1, and a lamp frame 3 mounted inside the curing box 2. A UV lamp tube 4 is movably mounted inside the lamp frame 3. Arc-shaped sliding slits 5 are opened on both sides of the lamp frame 3. Sliding columns 6 are fixed at both ends of the UV lamp tube 4. The two sliding columns 6 slide in the two sliding slits 5 respectively, so as to adjust the spacing and irradiation angle of the UV lamp tube 4 by sliding the sliding columns 6 along the sliding slits 5, and adapt to the drying and curing requirements of different substrates in aluminum paste circuit fabrication.

[0021] Referring to the prior art patent announcement number CN218906033U, “An ultraviolet curing tunnel oven drying equipment”, it can be seen that the belt conveyor 1, curing box 2, lamp frame 3, and UV lamp tube 4 are the technical features already published in the prior art. Its basic adaptation and general usage logic, such as carrying the lamp tube through the lamp frame and using the conveying mechanism to transfer the workpiece, can be referred to the prior art. The comparison will not be elaborated in detail.

[0022] The general usage is as follows: the circuit board coated with aluminum paste and waiting to be dried and cured is sent into the curing box 2 by the belt conveyor 1. The UV lamp tube 4 carried by the lamp frame 3 emits ultraviolet light to dry and cure the aluminum paste on the circuit board. In addition, the spacing and irradiation angle of the UV lamp tube 4 can be adjusted by sliding the sliding column 6 in the sliding joint 5 to adapt to the needs of aluminum paste circuit production.

[0023] Furthermore, referring to 2-4, it is worth noting that the outer side of the lamp frame 3 is provided with a positioning mechanism for conveniently locking the UV lamp tube 4.

[0024] The positioning mechanism includes a U-shaped swing frame 7 that is fixed to the top of the lamp frame 3 and an arc-shaped toothed plate 8 that is fixed to the side wall of the lamp frame 3. A telescopic latch is provided between the swing frame 7 and the arc-shaped toothed plate 8. The top of the swing frame 7 is provided with a driving part that cooperates with the telescopic latch. Two sliding columns 6 are respectively fixed to the inner walls on both sides of the swing frame 7. The curvature of the arc-shaped toothed plate 8 is adapted to the curvature of the sliding joint 5. By moving the swing frame 7 synchronously with the UV lamp tube 4, the driving part drives the telescopic latch to engage with the arc-shaped toothed plate 8, thereby locking the position of the UV lamp tube 4.

[0025] Unlike existing technologies that require manual loosening and tightening of the nut to adjust the UV lamp tube 4, this positioning mechanism, through the adaptation of the swing frame 7, the arc-shaped toothed plate 8, and the telescopic locking device, allows for quick locking or unlocking of the UV lamp tube 4 simply by operating the telescopic locking device via the drive unit. Workers no longer need to manually operate the nuts at both ends of the UV lamp tube 4 one by one, significantly reducing operational intensity and improving the convenience of adjusting the angle and spacing of the UV lamp tube 4, thus meeting the needs of frequent adjustments and curing parameters in aluminum paste circuit fabrication.

[0026] Furthermore, referring to Figure 3 As shown, it is worth noting that the telescopic clamp includes a slide plate 9 and two inserts 10 fixed at both ends of one side of the slide plate 9. The ends of the inserts 10 are inserted between two adjacent teeth of the arc-shaped toothed plate 8. An air chamber 11 is arranged transversely in the inner wall of the swing frame 7. A piston column 12 is slidably arranged in the air chamber 11. One end of the piston column 12 passes through the swing frame 7 and is fixedly connected to the other side of the slide plate 9.

[0027] The driving unit includes a drive box 13 fixed in the inner wall of the swing frame 7, a piston plate 14 that rises and falls in the inner side of the drive box 13, and an air pipe 16 fixedly connected to the bottom of the side wall of the drive box 13. The end of the air pipe 16 is inserted into the air chamber 11, and a screw 15 is threaded through the middle of the piston plate 14. The top of the screw 15 rotates out of the drive box 13.

[0028] By rotating the screw 15, the piston plate 14 moves upward along the inner wall of the drive box 13 due to the threaded engagement between the screw 15 and the piston plate 14. The air pressure at the bottom of the drive box 13 decreases, and the gas in the air chamber 11 flows to the drive box 13 through the air pipe 16, which reduces the air pressure in the air chamber 11. The piston column 12 drives the slide plate 9 to slide towards the swing frame 7, and the insertion column 10 exits between the teeth of the arc-shaped toothed plate 8, releasing the lock and allowing the UV lamp tube 4 to slide and adjust its position.

[0029] Conversely, rotating the screw 15 in the opposite direction causes the piston plate 14 to move down and compress the gas at the bottom of the drive box 13. The gas is then forced into the gas chamber 11 through the gas pipe 16, pushing the piston column 12 to move outward. The slide plate 9 drives the insert column 10 to insert into the teeth of the arc-shaped toothed plate 8, locking the position of the UV lamp tube 4.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
