Detailed implementation manners

[0021] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the following will describe in detail the specific implementation manners of the present utility model with reference to the accompanying drawings.

[0022] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the flat nozzle and needle integrated glue wiping device provided by the embodiment of the present application has a structure including a chassis 1, a dust-free cloth 2, a partition board 6 vertically arranged in the chassis 1, an unwinding mechanism 3 arranged on the partition board 6 for unwinding the dust-free cloth 2, a winding mechanism 4 for winding the dust-free cloth 2, and a plurality of tensioning shafts 5 arranged on the partition board 6 and located between the winding mechanism 4 and the unwinding mechanism 3. The partition board 6 is further provided with a needle wiping mechanism 8 and a flat nozzle wiping mechanism 7. The needle wiping mechanism 8 includes a first roller 81, a second roller 82, a third roller 83, and a clamping assembly 84 arranged on the partition board 6. The flat nozzle wiping mechanism 7 includes a floating plate 71 with a groove 701 on its upper end surface and a plurality of elastic support members 72 arranged on the chassis 1 for supporting the floating plate 71. The dust-free cloth 2 passes through the upper end surface of the floating plate 71 and is pulled by the first roller 81, the second roller 82, and the third roller 83 to form a V-shaped groove 801 with the notch facing upward. The clamping assembly 84 can clamp the dust-free cloth 2 from the outside of the V-shaped groove 801.

[0023] In actual use, the dust-free cloth 2 is pulled by the winding mechanism 4, so that the unwinding mechanism 3 automatically unwinds the dust-free cloth 2. The dust-free cloth 2 is pulled by several tensioning shafts 5 during the process of winding and unwinding, and passes through the needle wiping mechanism 8 and the flat nozzle wiping mechanism 7. When it is necessary to wipe the needle, the needle is extended from top to bottom into the V-groove 801 through the multi-axis mechanism of the glue dispenser, and then the clamping component 84 drives the dust-free cloth 2 forming the V-groove 801 to stick to each other and cover the needle. Then the multi-axis mechanism drives the needle to move up, and the glue remaining on the surface of the needle is wiped during the movement of the needle. When it is necessary to wipe the flat nozzle, the multi-axis mechanism of the glue dispenser drives the flat nozzle to move, so that the glue outlet of the flat nozzle is against the upper end surface of the dust-free cloth 2 corresponding to the groove 701, and ensures that the floating plate 71 is pressed to cause the elastic support member 72 to be compressed. As the dust-free cloth 2 is rolled up, the glue outlet of the flat nozzle is wiped.

[0024] In the above design, the needle wiping mechanism 8 and the flat nozzle wiping mechanism 7 are integrated, and the flat nozzle and needle integrated wiping device of the present application can simultaneously wipe the needle and the flat nozzle, effectively saving the cost of downstream manufacturers and improving the adaptability to different working conditions.

[0025] Specifically: Figure 2 As shown, the partition plate 6 is provided with a through hole 601. Figure 2 and Figure 3 As shown, the clamping assembly 84 includes a No. 1 clamping plate 841, a No. 2 clamping plate 842 and a clamping claw arranged on one side of the partition 6, and the clamping claw includes a cylinder body 843 fixedly arranged on one side of the partition 6 and a No. 1 claw toe 844 and a No. 2 claw toe 845 fixedly arranged on the cylinder body 843, the No. 1 clamping plate 841 is arranged on the No. 1 claw toe 844, and the No. 2 clamping plate 842 is arranged on the No. 2 claw toe 845, and the No. 1 clamping plate 841 and the No. 2 clamping plate 842 perform opening and closing movements in the through hole 601.

[0026] During actual use, the cylinder body 843 drives the No. 1 claw 844 and the No. 2 claw 845 to move toward each other, so that the No. 1 clamping plate 841 and the No. 2 clamping plate 842 respectively clamp the dust-free cloth 2 on both sides of the dust-free cloth 2 forming the V-shaped groove 801, so that the clamped dust-free cloth 2 covers the needle inserted into the V-shaped groove 801. When the needle is extracted, the dust-free cloth 2 covering the pillow can wipe the needle.

[0027] In the above design, the opening and closing movement of the first clamping plate 841 and the second clamping plate 842 can be effectively avoided through the design, and the structural design of the clamping assembly 84 and the specific implementation method can realize the rapid clamping of the dust-free cloth 2.

[0028] Specifically: Figure 3 ,Figure 4 and Figure 5 As shown in Figure 5 , the first roller 81, the second roller 82 and the third roller 83 are arranged on the other side of the partition plate 6. The first clamping plate 841 and the second clamping plate 842 have the same structure. The first clamping plate 841 includes a first plate 8411 arranged on the first claw toe 844, a second plate 8412 connected to the first plate 8411 and passing through the through hole 601, and a magic tape 8413 arranged on the second plate 8412. The first plate 8411 and the second plate 8412 form an L-shaped structure. The magic tape 8413 is used to abut against the clean cloth 2. When passing through the magic tape 8413, both sides of the clean cloth 2 are projected onto the magic tape 8413.

[0029] During actual use, the clean cloth 2 is pushed by the two magic tapes 8413 directly to realize the closing of the clean cloth 2.

[0030] In the above design, by setting the magic tape 8413, since the surface of the magic tape is a non-planar surface, when clamping the clean cloth 2, it can ensure that the clean cloth 2 circumferentially wraps the needle, ensuring that the needle is wiped cleaner.

[0031] Specifically: as Figure 6 and Figure 7 shown, the elastic support member 72 includes a limit screw 721, a connecting screw, a linear bearing 722 vertically and fixedly arranged on the chassis 1, a guide post 723 sleeved on the linear bearing 722, and a spring 724 sleeved on the guide post 723. The guide post 723 is provided with an internal thread. The floating plate 71 is provided with a countersunk hole 710 penetrating downward. The connecting screw passes through the countersunk hole 710 and is connected to the upper end of the internal thread. The limit screw 721 is connected to the lower end of the internal thread to prevent the guide post 723 from sliding upward and disengaging from the linear bearing 722. The two ends of the spring 724 abut against the lower end of the floating plate 71 and the upper end of the linear bearing 722 respectively.

[0032] During actual use, when the flat nozzle is wiping, the downward pressure of the flat nozzle on the floating plate 71 will cause the spring 724 to be compressed, so that the guide post 723 slides downward along the linear bearing 722 by a distance equal to the deformation amount of the spring 724. During the process of the flat nozzle completing the wiping and detaching from the clean cloth 2, the extrusion of the flat nozzle on the clean cloth 2 gradually decreases. Due to the elastic reset ability of the spring 724, it drives the floating plate 71 to drive the guide post 723 to reset.

[0033] In the above design, the structural design and specific implementation manner of the elastic support member 72 can effectively realize the elastic support of the floating plate 71, ensure that there is sufficient buffering during the process of the flat nozzle descending to contact the clean cloth 2, and ensure the safety of the clean cloth 2 and the flat nozzle.

[0034] Specifically: as Figure 3 andFigure 4 As shown, the unwinding mechanism 3 includes a first roll material rack rotatably arranged on one side of the partition plate 6, and the winding mechanism 4 includes a second roll material rack 42 arranged on one side of the partition plate 6, a motor 41 arranged on the other side of the partition plate 6, and a connecting shaft passing through the partition plate 6 to connect the output shaft of the motor 41 and the second roll material rack 42.

[0035] During actual use, the motor 41 drives the connecting shaft to rotate, the connecting shaft drives the second roll material rack 42 to rotate, and the second roll material rack 42 applies a traction force to one end of the dust-free cloth 2, so as to realize the automatic unwinding of the first roll material rack.

[0036] In the above design, the structural design and specific implementation manner of the unwinding mechanism 3 and the winding mechanism 4 can effectively realize the unwinding and winding of the dust-free cloth 2.

[0037] Specifically: a sponge is arranged in the groove 701, and the upper end surface of the sponge 701 abuts against the lower end surface of the dust-free cloth 2.

[0038] During actual use, when the glue outlet of the flat nozzle presses the dust-free cloth downward, the dust-free cloth will press the sponge downward, causing the sponge to be compressed and deformed.

[0039] In the above design, by arranging a sponge in the groove 701, not only can the buffer be stronger when the flat nozzle is wiping glue, and the protection effect on the glue outlet of the flat nozzle is stronger; but also the elasticity of the sponge can be utilized to ensure that the dust-free cloth 2 corresponding to the flat nozzle is pressed downward, while the dust-free cloth 2 around the glue outlet of the flat nozzle will be supported by the sponge in the opposite direction, wiping the periphery of the glue outlet of the flat nozzle more comprehensively, increasing the contact area between the glue outlet of the flat nozzle and the dust-free cloth 2, and making the glue outlet of the flat nozzle wiped cleaner.

[0040] It should be further understood in detail that the above description is only specific embodiments of the present invention and is not used to limit the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
