[0018] As Figures 1-4 shown, the glue layer thickness controllable type gluing mechanism, including for card solid cartridge sealant 100 for gluing operation glue gun, the glue gun is vertically downward, opposite the gear box joint place of gluing surface 200.

[0019] Specifically, the glue gun includes a lower clamp seat 2 and an upper clamp seat 3 connected by a connecting plate 1, a clamping cavity 4 for clamping the cartridge sealant 100 is formed between the lower clamp seat 2 and the upper clamp seat 3; a glue outlet hole 5 is formed from top to bottom on the lower clamp seat 2, a push rod 6 is provided on the upper clamp seat 3, the axis of the glue outlet hole 5 and the push rod 6 are consistent, and an operation unit 7 and a locking unit 8 are provided to drive the push rod 6 to move vertically downward.

[0020] The glue outlet hole 5 is composed of a tapered hole 5.1 with a large upper part and a small lower part, and a cylindrical hole 5.2 connected to the bottom of the tapered hole 5.1. The tapered hole 5.1 can not only clamp the glue outlet end of the cartridge sealant 100, but also adapt to cartridge sealants 100 of different diameters.

[0021] As Figure 2As shown, the operation unit 7 includes a fixed handle 7.1 fixed to the upper holder 3, and a pressing handle 7.2 matched with the fixed handle 7.1, the pressing handle 7.2 is connected with a pressing plate 7.3 rotating therewith, the pressing plate 7.3 is obliquely arranged, and a first clamping hole 7.4 perpendicular to the plate surface is formed in the pressing plate 7.3, and a return spring 7.5 pushing the pressing plate 7.3 upward is arranged on the upper holder 3 below the pressing plate 7.3.

[0022] As shown, Figure 3 The locking unit 8 includes a locking plate 8.1 hinged to the upper holder 3, the locking plate 8.1 is obliquely arranged, and a second clamping hole 8.2 perpendicular to the plate surface is formed in the locking plate 8.1, and a locking spring 8.3 pushing the locking plate 8.1 upward is arranged on the upper holder 3 below the locking plate 8.1.

[0023] At this time, the push rod 6 should pass through the first clamping hole 7.4, the return spring 7.5, the second clamping hole 8.2 and the locking spring 8.3 in turn, and the upper end of the push rod 6 is bent to one side to form a holding end 9 for easy gripping, and a pressing block 10 is screwed to the lower end of the push rod 6, which can extend into the cylinder sealant 100 from the side away from the glue outlet and push the push plate in the cylinder sealant 100, so as to extrude the sealant from the glue outlet.

[0024] In addition, a glue scraping unit is also arranged on the lower holder 2 at the lower end of the glue gun, which includes a roller 11 for walking on the glue applying surface 200 at the gear box closing place, and a connecting frame 12 is arranged in the walking direction of the roller 11, the connecting frame 12 is provided with a height adjusting rod 13 perpendicular to the glue applying surface 200, the lower end of the height adjusting rod 13 is fixedly connected with a scraping plate 14, the scraping plate 14 is horizontally arranged, and the side edge close to the glue gun is folded upward to form a flange 15, so as to better scrape the sealant extruded by the glue gun; a dial gauge 16 is arranged on the connecting frame 12 above the height adjusting rod 13, the dial gauge 16 is provided with a measuring plunger 17 vertically downwardly abutting on the upper end of the height adjusting rod 13, the height of the height adjusting rod 13 can be easily measured by the dial gauge 16, and then the distance between the scraping plate 14 at the lower end of the height adjusting rod 13 and the glue applying surface 200 at the gear box closing place is determined, so as to accurately control the glue applying thickness.

[0025] Specifically, the roller 11 is four groups, which are evenly distributed on the bottom surface of the lower holder 2; and the connecting frame 12 is an integral structure of a frame body composed of a connecting vertical rod 12.1 and a connecting horizontal rod 12.2. At this time, in order to facilitate the fixation of the entire connecting frame 12 on the holder 2, an internal hexagonal screw 18 should be horizontally arranged at the lower end of the connecting vertical rod 12.1, and the entire connecting frame 12 is screwed and fixed to the side wall of the lower holder 2 through the internal hexagonal screw 18. Of course, in order to ensure that the internal hexagonal screw 18 can stably fix the connecting frame 12, an elastic anti-skid pad can also be arranged in the internal hexagonal screw 18.

[0026] To achieve height adjustment of the height adjustment rod 13 on the connecting frame 12, as shown in FIG. Figure 4 As shown, a through hole 19 for the height adjustment rod 13 to pass through should also be vertically opened on the connecting cross bar 12.2, and a fastening bolt 20 for fixing the height adjustment rod 13 is screwed through the rod wall of the connecting cross bar 12.2 on one side of the through hole 19.

[0027] To facilitate the installation or disassembly of the dial indicator 16, a threaded connection hole 21 should be horizontally opened on the connecting vertical rod 12.1 located above the connecting horizontal rod 12.2, and a threaded connection rod 22 that can be adapted to be screwed into the threaded connection hole 21 is provided on the side wall of the dial indicator 16. When the height adjustment rod 13 is adjusted to the point where the lower surface of the scraper plate 14 is flush with the walking surface of the roller 11, the threaded connection rod 22 is completely tightened and screwed into the threaded connection hole 21. At this time, the measuring pin 17 on the dial indicator 16 should just touch the upper end of the height adjustment rod 13.

[0028] When using, Figure 5 As shown, first, the cartridge sealant 100 is secured in the cavity 4 between the lower and upper cartridges 2 and 3, with the discharging end of the cartridge sealant 100 facing downward and extending into the discharging hole 5. The push rod 6 is unlocked by pulling the locking plate 8.1 downward, so that the pressure block 10 at the lower end of the push rod 6 abuts against the push plate of the cartridge sealant 100 away from the discharging end, completing the loading of the cartridge sealant 100 onto the glue gun. The entire mechanism is then placed on the glue coating surface 200 at the gearbox assembly, with the four rollers 11 resting stably on the glue coating surface 200. The height adjustment rod 13 is then adjusted according to the desired glue coating thickness. The distance between the lower surface of the scraper plate 14 and the glue coating surface 200 (i.e., the glue coating thickness) is accurately determined based on the indication of the dial indicator 16, and the height adjustment rod 13 is secured with the fastening bolt 20.

[0029] After the above operations are completed, the fixed handle 7.1 can be held and the pressing handle 7.2 can be repeatedly pressed to move the push rod 6 downward, thereby pushing the push plate of the tube sealant 100, so that the sealant inside is squeezed out from the glue outlet end and applied to the glue surface 200 at the gear box assembly through the glue outlet hole 5. While applying the glue, the roller 11 is used to move along the glue surface 200, so that the scraper 14 can scrape the sealant applied to the glue surface 200 flat and ensure the pre-set glue thickness. The glue layer thickness controllable glue coating mechanism has a simple structure, easy operation, and low manufacturing cost. It can easily complete the glue coating task and the glue scraping task at the same time, avoiding the two-step operation of glue coating and glue scraping, ensuring that the thickness of the glue layer can be accurately controlled, so that any operator can quickly get started and achieve a consistent thickness of glue coating operation, ensuring that the glue coating results can be quantitatively controlled, and greatly improving the glue coating efficiency of the gear box assembly.
