[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present invention.

[0032] In the figure, units with similar structures are denoted by the same reference numerals.

[0033] Please refer to Figure 1 , an integrated glue applying and scraping machine of the present invention is used to process semi-finished material sheets. The semi-finished material sheet 9 includes two material sheets 92, and the excess glue 91 is connected between the two material sheets 92. During the plastic sealing process of the material sheet 92, the two material sheets 92 are simultaneously plastic sealed in the same mold, and the excess glue 91 is formed between them, which can reduce the amount of excess glue 91, save costs, and improve the plastic sealing efficiency.

[0034] The integrated glue applying and scraping machine includes a glue applying mechanism 2 and a glue scraping mechanism 1. The glue applying mechanism 2 is slidably arranged above the glue scraping mechanism 1 along the vertical direction Z. When the glue applying mechanism 2 moves downward, it can knock off the excess glue 91 from the semi-finished material sheet 9. After that, the glue scraping mechanism 1 scrapes the surface of the material sheet 92 connected to the excess glue 91 to make it neat, so as to remove the burrs at the water inlet of the surface to be glue scraped of the material sheet 92.

[0035] Combined with Figure 1 and Figure 2 As shown, the glue scraping mechanism 1 includes a base 11, a scraper 12 and a glue scraping driving member 13. The base 11 is used to place the material sheet 92, and the glue scraping driving member 13 is connected to the scraper 12 and is used to drive the scraper 12 to scrape the glue on the surface of the material sheet 92 to make it neat.

[0036] Combined with Figure 2 and Figure 3As shown, the base 11 is used to place the sheet 92, and a hollowed-out area 110 is provided thereon. The hollowed-out area 110 is a long strip arranged along the transverse direction X, and the surfaces to be coated with glue of the two sheets 92 are respectively located at the two opposite longitudinal Y edges of the hollowed-out area 110.

[0037] As Figure 3 , Figure 4 shown, the scraper 12 is located at the hollowed-out area 110, and it includes a tool holder 121 and two tool blocks 122. The tool holder 121 slides along the transverse direction X on the base 11; the cutting edges 1220 of the two tool blocks 122 are arranged in opposite directions in the longitudinal direction Y and are respectively used for coating the surfaces to be coated with glue of the two sheets 92. The two tool blocks 122 are slidably arranged along the longitudinal direction Y on the tool holder 121, and a coating pressure spring (not shown in the figure) is arranged between them. The coating pressure spring is used to provide a force for the two tool blocks 122 to move away from each other. The two tool blocks 122 can be used to coat the two sheets 92 respectively, and through the coating pressure spring, a buffering force can be provided for the two tool blocks 122 to avoid damaging the sheet 92.

[0038] As Figure 5 shown, the coating driving member 13 is arranged at the bottom of the base 11 and is connected to the tool holder 121 to drive the scraper 12 to move transversely, so as to use the two tool blocks 122 to coat the sheet 92 to remove the gate burrs. The structure is simple, the cost is low, and the coating efficiency is effectively improved.

[0039] As Figure 3 , Figure 4 shown, the tool block 122 includes a cutting edge portion 1221. On the side where the two cutting edge portions 1221 face away from each other, there are two inclined surfaces. Both of the two inclined surfaces are vertical, and the distance between the two inclined surfaces gradually decreases in the transverse direction and intersects to form an arc-shaped cutting edge 1220. The arc surface can be used to coat the sheet 92 and reduce the damage to the sheet 92. The structure of the cutting edge portion 1221 is simple, which is convenient for processing and preparation and reduces the cost.

[0040] As Figure 3 , Figure 4 shown, the tool block 122 further includes a limiting portion 1222 and a sliding portion 1223; in the vertical direction, the limiting portion 1222 is connected between the cutting edge portion 1221 and the sliding portion 1223. A guiding groove 1210 arranged along the longitudinal direction is provided on the tool holder 121. Both ends and the top of the guiding groove 1210 are open. At the top opening of the guiding groove 1210, there are two first limiting edges 1211, which are respectively arranged at the two transverse edges of the guiding groove 1210. The sliding portion 1223 is slidably arranged in the guiding groove 1210 and is limited below the first limiting edges 1211, and the limiting portion 1222 is located between the two first limiting edges 1211.

[0041] During assembly, the sliding portion 1223 of the blade block 122 can be respectively inserted into the guide groove 1210 from the openings at both ends of the guide groove 1210. The limiting portion 1222 is located between the two first limiting edges 1211, so that the blade portion 1221 can extend from the top opening of the guide groove 1210; the sliding portion 1223 can be limited in the guide groove 1210 by using the first limiting edge 1211, so that it will not fall out of the top opening of the guide groove 1210. The structure is simple and is conducive to the assembly of the various components of the scraper 12.

[0042] The two limiting parts 1222 have opposite sides protruding from the blade part 1221. The limiting parts 1222 can improve the structural strength between the blade part 1221 and the sliding part 1223. The second limiting edges 1101 are arranged at the edge of the hollow area 110. The second limiting edges 1101 are two and are arranged at the two longitudinal edges of the hollow area 110 respectively. The limiting parts 1222 are limited below the second limiting edges 1101. The second limiting edges 1101 can be used to limit the limiting parts 1222 in the vertical direction to ensure the stability of the blade block 122 sliding in the lateral direction.

[0043] Both lateral ends of the second limiting edges 1101 are inclined guide surfaces. The guide surfaces can facilitate the scraper 12 to enter between the two second limiting edges 1101, thereby making it convenient to install the scraper 12 into the hollow area 110.

[0044] In this embodiment, Figure 2 As shown, there are two hollow regions 110 arranged in the longitudinal direction, and two blank semi-finished products 9 can be processed simultaneously. Accordingly, there are two scrapers 12, which are respectively arranged at the two hollow regions 110.

[0045] like Figure 5 As shown, the scraper drive 13 is located below the base 11 between the two hollow areas 110, which can prevent the residual glue 91 and the scraper residue from falling onto the scraper drive 13 during the glue application process, thereby affecting the normal operation of the scraper drive 13. The scraper drive 13 is connected to the two knife seats 121 through the scraper slide 14 to drive the two scrapers 12 to move simultaneously. The scraper drive 13 adopts a magnetically coupled rodless cylinder, which is arranged in the horizontal direction, has a simple structure, and is easy to control. Of course, in other embodiments, a matching mechanism of a motor and a ball screw can also be used.

[0046] A slide rail mechanism 15 is provided between the bottom surface of the base 11 and the top surface of the rubber scraping slider 14. The slide rail mechanism 15 includes a slide rail 151 and a slider 152 that are slidably engaged. The slide rail 151 is fixed to the bottom surface of the base 11, and the slider 152 is fixed to the top surface of the rubber scraping slider 14. Through the cooperation of the slider 152 and the slide rail 151, the stability of the rubber scraping slider 14 sliding in the transverse direction and the balance between the two scraping blades 12 are improved. There are two groups of slide rail 151 mechanisms, arranged longitudinally to better ensure balance. The slide rail 151 mechanism is located at the position between the two hollow areas 110.

[0047] As Figure 1 shown, there are columns 16 provided on the base 11. The two columns 16 are respectively located at the transverse two ends of the base 11, and the number of columns 16 can be set as required.

[0048] As Figure 6 、 Figure 7 、 Figure 8 shown, the caulking mechanism 2 includes a lifting assembly 21 and a pressing plate 22. The lifting assembly 21 is located above the pressing plate 22, and a pressing spring 24 is provided between the two. The pressing spring 24 is used to provide an elastic force to move the lifting assembly 21 and the pressing plate 22 away from each other, so that the sheet 92 is pressed between the pressing plate 22 and the base 11. The lifting assembly 21 is slidably arranged vertically on the column 16 and is connected to a lifting driving member (not shown in the figure) to move vertically under the drive of the lifting driving member. The pressing plate 22 is provided with a hollow hole 220, and the hollow hole 220 is correspondingly arranged with the hollow area 110 to avoid interfering with the movement of the scraping blade 12. The pressing plate 22 is slidably connected vertically to the bottom of the lifting assembly 21 so that the two can move closer to or away from each other. A caulking column 219 is provided at the bottom of the lifting assembly 21, and the caulking column 219 passes through the hollow hole 220, and its bottom end is used to abut against the remaining glue 91.

[0049] In the initial state, the caulking mechanism 2 is located at a relatively high position away from the base 11, and the pressing plate 22 and the lifting assembly 21 are in a position away from each other. When performing caulking operations, the caulking driving member drives the lifting assembly 21 to move downward. When the pressing plate 22 and the lifting assembly 21 are in a position away from each other and the pressing plate 22 contacts the material sheet 92, the bottom surface of the caulking column 219 is in a separated state from the remaining glue 91; the lifting assembly 21 continues to move downward, and the distance between the pressing plate 22 and the lifting assembly 21 decreases. The pressing spring 24 provides elastic force so that the material sheet 92 can be pressed between the pressing plate 22 and the base 11, fixing the position of the material sheet 92. The lifting assembly 21 further moves downward, the bottom surface of the caulking column 219 abuts against the remaining glue 91 and drives the remaining glue 91 to move downward. The connection between the remaining glue 91 and the material sheet 92 breaks, and the two are separated. The remaining glue 91 drops, thus knocking off the remaining glue 91. Through the above structure, after the material sheet 92 is pressed by the pressing plate 22, the remaining glue 91 can be knocked off by the caulking column 219, and the surface to be caulked of the material sheet 92 can be scraped flat by the scraper 12. The structure is simple. Using the caulking mechanism 2 can facilitate caulking and scraping operations, and there is no need to set additional structures on the base 11 to fix the material sheet 92.

[0050] A guiding mechanism 23 is provided between the pressing plate 22 and the lifting assembly 21. The guiding mechanism 23 includes a linear bearing 232 and a guiding column 231 movably inserted into the linear bearing 232. A fixing hole 223 is provided on the top surface of the pressing plate 22. The bottom end of the guiding column 231 is threadedly connected to the fixing hole 223, and a limiting cap 2311 is provided at the top end of the guiding column 231. The linear bearing 232 is fixed to the lifting assembly 21 to ensure the stability of the relative movement between the two.

[0051] The lifting assembly 21 includes a lifting plate 211, an intermediate plate 212, and a bottom plate 213 fixedly connected in sequence from top to bottom. The lifting plate 211 is slidably arranged on the column 16. An activity hole 2110 is provided on the lifting plate 211, a limiting hole 2121 and a positioning hole 2122 are provided on the intermediate plate 212, and a mounting hole 2131 is provided on the bottom plate 213. The activity hole 2110, the limiting hole 2121, the positioning hole 2122, and the mounting hole 2131 are coaxially arranged. The diameters of the positioning hole 2122 and the activity hole 2110 are both larger than the diameter of the limiting hole 2121. The linear bearing 232 is arranged in the mounting hole 2131, and a flange 2321 is provided at its top. The flange 2321 is located in the positioning hole 2122. The limiting cap 2311 is vertically movably arranged in the activity hole 2110, and its outer diameter is larger than the diameter of the limiting hole 2121. By using the cooperation between the limiting cap 2311 and the edge of the activity hole 2110, the maximum downward sliding stroke of the guiding column 231 relative to the lifting assembly 21 can be limited.

[0052] When assembling the caulking mechanism 2, the linear bearing 232 can be first installed into the mounting hole 2131 of the bottom plate 213, with its flange 2321 located on the top surface of the bottom plate 213, and the flange 2321 is fixedly connected to the bottom plate 213 by screws. The intermediate plate 212 is fixed to the top surface of the top plate, and the flange 2321 is located in the positioning hole 2122, thereby reliably installing the linear bearing 232 between the bottom plate 213 and the intermediate plate 212.

[0053] The bottom end of the guide post 231 is sequentially passed through the limit hole 2121 and the linear bearing 232. The limit cap 2311 at the top end of the guide post 231 can be exposed on the top surface of the intermediate plate 212, facilitating screwing the limit cap 2311 to threadedly connect the bottom end of the guide post 231 to the pressing plate 22.

[0054] After the compression spring 24 is arranged between the bottom plate 213 and the pressing plate 22, the bottom end of the guide post 231 is threadedly connected to the fixing hole of the pressing plate 22. Finally, the lifting plate 211 is fixed to the top surface of the intermediate plate 212 by screws, completing the assembly of the lifting assembly 21 and realizing the connection between the pressing plate 22 and the lifting assembly 21. By using the cooperation of the lifting plate 211, the intermediate plate 212, and the bottom plate 213, the structural strength of the lifting assembly 21 can be improved, and it is beneficial to the installation of the guiding mechanism 23. The limit cap 2311 at the top end of the guide post 231 can move in the moving hole 2110 of the lifting plate 211 and will not protrude from the top surface of the lifting plate 211, ensuring that the movement of the guide post 231 is not interfered by the outside, so as to facilitate the connection between the top surface of the lifting plate 211 and the lifting driving member.

[0055] There can be multiple compression springs 24, evenly distributed between the pressing plate 22 and the lifting assembly 21, to ensure the balance and stability of the elastic force between the two.

[0056] In this embodiment, as Figure 8 shown, a first pressing groove 2134 is provided on the bottom surface of the bottom plate 213, and a second pressing groove 224 is provided on the top surface of the pressing plate 22. The first pressing groove 2134 and the second pressing groove 224 are arranged opposite to each other vertically, and the two ends of the compression spring 24 are respectively limited in the first pressing groove 2134 and the second pressing groove 224, facilitating the positioning installation and telescopic deformation of the compression spring 24.

[0057] Connecting ears 2112 are provided at both lateral ends of the lifting plate 211. The two connecting ears 2112 are respectively slidably connected to the two columns 16. The connecting ears 2112 protrude relative to the intermediate plate 212 and the bottom plate 213, preventing the intermediate plate and the bottom plate from rubbing against the columns. By using the two columns, the caulking mechanism and the scraping mechanism can be connected into an integral structure, facilitating the overall assembly onto other equipment.

[0058] In summary, although the present utility model has been disclosed above with preferred embodiments, the above preferred embodiments are not intended to limit the present utility model. Those of ordinary skill in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the scope defined by the claims.
