Description

Technical Field

[0001] The utility model relates to a glue adding device, in particular to a glue adding device for double-sided PCB boards. Background Art

[0002] A PCB board is a circuit board, and some electronic components need to be connected to the circuit board to work together to produce an effect.

[0003] Sometimes, components are located on both sides of the PCB, so glue needs to be added to both sides of the PCB board to complete the connection between the components and the board.

[0004] In the existing glue filling process, a limiting soft strip for preventing glue overflow is first injected onto the PCB, and then glue is injected inside the limiting soft strip. There are several defects in this kind of glue filling:

[0005] 1. When filling glue, the pouring head for injecting glue is generally fixed, and the glue is left to flow and dry naturally, resulting in a slow glue adding efficiency.

[0006] 2. In this glue filling method, glue is first filled on the upper side. After the filling is completed, the PCB board is then turned over. This requires positioning and clamping the PCB board twice, which affects the operation efficiency of glue adding.

[0007] 3. During the turning process, for specific glue adding areas, there may be problems of deviation and displacement of positions within the area during turning. When the deviation is not detected in time, it affects the yield of the PCB board. Summary of the Utility Model

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0031] Please refer to Figures 1-5, as an embodiment of the present utility model, the gluing device for the double-sided PCB includes a base 1, and a flipping mechanism and a gluing mechanism are arranged above the base 1; the gluing mechanism includes a glue adding tube 20;

[0032] The gluing mechanism is arranged above the flipping mechanism, and the flipping mechanism and the gluing mechanism cooperate with each other through a transmission mechanism;

[0033] The flipping mechanism includes a motor 4 and a support frame 9. When the motor 4 in the flipping mechanism starts to operate, the glue adding tube 20 of the gluing mechanism starts to add glue. After the glue adding of the glue adding tube 20 is completed, the support frame 9 in the flipping mechanism starts to flip. During the flipping process of the support frame 9, the glue adding tube 20 returns to the initial position. After the flipping of the support frame 9 is completed, the glue adding tube 20 then continues to add glue to the other side that has been flipped up.

[0034] In this embodiment, the double-sided gluing of the PCB board is completed through the mutual cooperation of the flipping mechanism and the gluing mechanism. When the PCB board needs to be glued, the PCB board is placed on the support frame 9, and the motor 4 is started. The motor 4 drives the glue adding tube 20 to start adding glue to the PCB board at its bottom through the transmission mechanism. When the gluing of the PCB board is completed, at this time, the flipping mechanism starts to drive the support frame 9 to flip. During the flipping process, the glue adding tube 20 returns to the initial position under the drive of the transmission mechanism. After the flipping is completed, when the other side is located below the glue adding tube 20, the glue adding tube 20 starts a new round of gluing, thus completing the fast and convenient gluing of both sides of the PCB board.

[0035] As a further solution of the present utility model, a vertical guide frame 2 is arranged on the base 1, and a horizontal guide frame 3 is arranged at the top of the vertical guide frame 2, and both the vertical guide frame 2 and the horizontal guide frame 3 are used for the support and connection of other parts.

[0036] In this embodiment, a vertical guide frame 2 and a horizontal guide frame 3 are respectively arranged above the base 1, so as to facilitate the connection of other parts and make the whole device more stable.

[0037] As a further solution of the present utility model, the flipping mechanism further includes a driving wheel 6, a driven wheel 7 and a horizontal guide shaft 8. The horizontal guide shaft 8 is rotatably connected to the base 1. The motor 4 is connected to the side of the base 1. The driving wheel 6 is connected to one end of the output shaft of the motor 4. The driving wheel 6 and the driven wheel 7 cooperate with each other, so that one rotation of the driving wheel 6 drives the driven wheel 7 to rotate half a circle. The horizontal guide shaft 8 is connected to one end of the support frame 9, and the driven wheel 7 and the support frame 9 are connected through the horizontal guide shaft 8 and a connecting block.

[0038] In this embodiment, when the motor 4 rotates, it drives the driving wheel 6 to rotate. While the driving wheel 6 rotates one full circle, it drives the driven wheel 7 to rotate half a circle, that is, 180 degrees. Similarly, the driven wheel 7 drives the support frame 9 to rotate 180 degrees through the horizontal guide shaft 8, so that the support frame 9 flips the other side of the PCB board on its surface upwards.

[0039] As a further solution of the present utility model, a torsion spring 10 is arranged on the connecting block through a guide frame. One end of the torsion spring 10 abuts against the connecting block, and a pressing plate 11 abuts against one end of the torsion spring 10. The pressing plate 11 is arranged on the surface of the support frame 9, and a rotating shaft is arranged at one end of the pressing plate 11 close to the torsion spring 10 and is rotatably connected to the connecting block.

[0040] In this embodiment, when it is necessary to clamp the PCB board on the support frame 9, first pull the pressing plate 11 upwards. At this time, the pressing plate 11 rotates around its own rotating shaft and compresses the torsion spring 10. At this time, the torsion spring 10 is in a compressed state. Then, the PCB board can be placed between the support frame 9 and the pressing plate 11. Under the reset action of the torsion spring 10, the pressing plate 11 firmly clamps the PCB board.

[0041] As a further solution of the present utility model, the transmission mechanism includes a first belt pulley 5, a belt strip 12, a second belt pulley 13, a first bevel gear 14 and a second bevel gear 15;

[0042] The motor 4 cooperates with the transmission mechanism. The first belt pulley 5 is connected to the output shaft of the motor 4. The first belt pulley 5 and the second belt pulley 13 are connected by the belt strip 12. The first bevel gear 14 is connected to the second belt pulley 13. The second bevel gear 15 meshes with the first bevel gear 14, and the second bevel gear 15 cooperates with the glue application;

[0043] The second belt pulley 13 is rotatably connected to the vertical guide frame 2.

[0044] In this embodiment, when the motor 4 drives the driving wheel 6 to rotate, it also drives the first belt pulley 5 to rotate. Similarly, the first belt pulley 5 drives the second belt pulley 13 to rotate through the belt strip 12. The second belt pulley 13 drives the first bevel gear 14 to rotate. Since the first bevel gear 14 and the second bevel gear 15 are in a meshing relationship, it drives the second bevel gear 15 to rotate synchronously. The second bevel gear 15 drives the glue application mechanism to rotate.

[0045] As a further solution of the present utility model, the glue application mechanism further includes a small gear 16, a large gear 17, a vertical guide rod 18, a longitudinal guide frame 19 and a guide rail 21;

[0046] The pinion gear 16 is connected to the top of the second bevel gear 15. The large gear 17 meshes with the pinion gear 16. The vertical guide rod 18 is connected to the bottom of the large gear 17. The longitudinal guide frame 19 is slidably engaged with the vertical guide rod 18. The longitudinal guide frame 19 is connected to the glue adding pipe 20. The glue adding pipe 20 is arranged inside the guide rail 21 and is slidably engaged with the guide rail 21.

[0047] In this embodiment, the rotation of the second bevel gear 15 drives the rotation of the pinion gear 16, and the pinion gear 16 drives the rotation of the large gear 17. Since the radii of the pinion gear 16 and the large gear 17 are different, through the principle of the small driving the large of the gears, the pinion gear 16 completes the speed reduction conversion for the large gear 17, making the rotation speed of the large gear 17 slow down, and also making the operation of the glue adding pipe 20 more stable. When the large gear 17 rotates, it will push the longitudinal guide frame 19 to make a linear reciprocating motion in the horizontal direction as shown in the figure through the vertical guide rod 18, thereby driving the glue adding pipe 20 to make a linear reciprocating motion above the PCB board.

[0048] It should be noted that when the glue adding pipe 20 moves from the left side to the right side in the shown direction, the support frame 9 starts to flip. During the flipping process, the glue adding pipe 20 moves from the right side to the left side again as shown. And after the support frame 9 finishes flipping, the glue adding pipe 20 just returns to the initial position as shown. Figure 1 Thus, the perfect cooperation between the flipping mechanism and the glue adding mechanism is achieved, realizing the rapid and convenient double-sided glue adding to the PCB board. Figure 1 Figure 1 Figure 1

[0049] As a further solution of the present utility model, a glue supply container 22 is arranged on the transverse guide frame 3, and the glue supply container 22 is placed on a storage rack. The glue supply container 22 is connected to the glue adding pipe 20 through a connecting hose 23.

[0050] In this embodiment, a storage rack is installed on the transverse guide frame 3, and the glue supply container 22 is placed on the storage rack to facilitate timely replenishment of glue into the glue supply container 22, and then injected into the glue adding pipe 20 through the connecting hose 23.

[0051] As a further solution of the present utility model, a heater 24 is arranged on the vertical guide frame 2, and the heater 24 is used to timely dry the glue just injected onto the PCB board.

[0052] In this embodiment, while the glue adding pipe 20 injects glue onto the PCB board, hot air is blown out inside the heater 24 to timely dry the just-injected glue, so that the components on the PCB board are quickly bonded to the PCB board.

[0053] The above embodiments are illustrative and not restrictive. Therefore, all technical solutions that can implement the present invention in other specific forms without departing from the spirit or basic characteristics of the present invention are encompassed within the present invention.
