Detailed Description

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the embodiments of the present invention, the terms "upper" and "lower", etc. are not intended to limit a specific direction, but are for convenience of description and illustration.

Fig. 1 is a schematic view showing a gluing apparatus for manufacturing pouch batteries according to the prior art.

Referring to fig. 1, the conventional gluing apparatus 100 may include a housing 110, an air cylinder 120, a glue barrel 130, and a receiving groove 140.

As shown in fig. 1, the conventional gluing apparatus 100 may include two air cylinders 120 disposed in parallel on the top of a housing 110. The two cylinders 120 may be connected with two piston rods 122 extending to the inside of the housing 110, respectively. One ends of the piston rods 122 extending into the housing 110 may be respectively provided with pistons 123.

During operation of the gluing apparatus 100, the cylinder 120 may drive the piston rod 122 to move in a direction perpendicular to the top surface of the housing 110, and may further drive the piston 123 to move toward the glue barrel 130. In addition, the glue application apparatus 100 may further include a cylinder adjusting valve 124 provided at the top of the case 110.

As shown in fig. 1, the conventional gluing apparatus 100 may include two glue cartridges 130 disposed in parallel inside the housing 110. The two glue barrels 130 may be respectively located below the two pistons 123. The glue cartridge 130 may include a plug 131 and a glue 132 disposed therein. The plug 131 may be positioned above the gel 132. The glue barrel 130 may also include a first opening and a second opening. The plug body 131 may be disposed adjacent to the first opening. The second opening of the glue bucket 130 may be connected to a receiving groove 140 located below the glue bucket 130.

During the operation of the glue spreading apparatus 100, the glue 132 inside the glue barrel 130 may be softened and formed into a liquid glue 132 by a heating device (not shown) disposed around the glue barrel 130. Then, the piston 123 may be driven by the cylinder 120 to move through the first opening of the glue barrel 130, thereby pushing the plug body 131 to move downward. The liquid gel 132 can flow into the accommodating groove 140 through the second opening under the pushing of the piston 123. However, the gel may be transported to a nozzle (not shown) using a throat (not shown) connected to the gel outlet 141, and the gel 132 may be sprayed onto the respective components.

In the conventional glue spreading apparatus 100, since the glue 132 is solid at normal temperature, in order to keep the glue 132 in a liquid state during the glue spreading process, it is often necessary to provide heating means around a glue barrel storing the glue 132, a throat transporting the glue 132, and a nozzle. In this case, the gluing device is complex in structure and takes up a large space, which increases the difficulty of its maintenance and the cost of its maintenance. Meanwhile, the gluing equipment is easy to have poor gluing in the using process.

In order to solve at least one of the above problems, a gluing apparatus according to the present invention will be described in detail below with reference to fig. 2 and 3.

Fig. 2 is a schematic diagram showing a gluing device for manufacturing a pouch battery according to the present invention. Fig. 3 is a sectional view showing the gluing apparatus of fig. 2 according to the present invention.

As shown in fig. 2 and 3, the gluing apparatus 200 according to the present invention may include a heating jacket 210, a sealing cover 230, and a glue barrel 250.

As shown in fig. 3, the heating jacket 210 may be disposed around the glue barrel 250. The heating jacket 210 may be connected with a heating electrode (not shown) to heat the glue barrel 250 during the gluing process. The heating jacket 210 may have a first opening and a second opening, and the cross-sectional area of the first opening is larger than the cross-sectional area of the second opening. In an embodiment according to the present invention, the heating jacket 210 may be an aluminum sleeve, a copper jacket, or a combination of the aluminum jacket and the copper jacket.

Specifically, as shown in fig. 3, for example, the heating jacket 210 may include a first portion having a first opening and a second portion having a second opening, the first portion having a constant sectional area (e.g., a cylindrical shape), the second portion being connected to the first portion and having a gradually decreasing sectional area (e.g., a pyramidal shape) in a direction away from the first portion, as viewed from the outside. In addition, the inner space of the heating jacket drum 210 in which the glue drum 250 is accommodated may have a shape similar to the outer shape or a shape different from the outer shape (e.g., a bottle shape). Specifically, the inner space of the heating jacket 210 may include: a first portion having a constant first inner diameter; a second portion having a constant second inner diameter, the second inner diameter being smaller than the first inner diameter; and a third portion connecting the first portion and the second portion and having an inner diameter that tapers from the second inner diameter to the first inner diameter. However, embodiments according to the present invention are not limited thereto, and the heating jacket 210 may have any suitable shape.

The glue barrel 250 may be housed in the heating jacket barrel 210. As shown in fig. 3, the glue bucket 250 may have a shape (e.g., a bottle shape) similar to the shape of the inner space of the heating jacket bucket 210, and the glue bucket 250 may have a third opening and a fourth opening. The third opening may be disposed adjacent to the first opening of the heating jacket drum 210, and the fourth opening may be disposed adjacent to the second opening of the heating jacket drum 210 and coupled to the nozzle 290 of the gluing apparatus 200. A gel (not shown) and a plug 251 positioned above the gel may be contained in the gel cartridge 250. The plug body 251 is movable by an external force.

The sealing cover 230 may be disposed at the first opening of the heating jacket 210 and serves to seal the first opening. The sealing cover 230 may be provided with an intake terminal 231 receiving gas from an external device.

In the process of gluing using the gluing apparatus 200, the heating jacket 210 may heat the glue barrel 250 to melt the glue inside the glue barrel 250. Then, the gas passing through the gas inlet terminal 231 may enter the third opening of the glue barrel and push the plug body 251 to move toward the fourth opening, thereby causing the glue to be sprayed from the nozzle 290. In addition, when the glue in the glue bucket 250 is used up, the sealing cover 230 may be opened and a new glue bucket 250 may be replaced.

Consequently, for traditional rubber coating equipment, according to the utility model discloses a rubber coating equipment can omit subassembly such as cylinder, choke, piston rod, cylinder governing valve and holding tank. Therefore, the gluing device can have a simple structure and a small size, thereby reducing the difficulty of maintenance and the cost of maintenance. Meanwhile, the probability of poor gluing can be reduced by the gluing equipment.

As shown in fig. 2 and 3, the gluing apparatus 200 may further include a fixing case 220, a sealing cover pressing device 240, a glue barrel fastening member 260, and a platform connecting rod 280.

As shown in fig. 2, a stationary housing 220 may be disposed around the heating jacket 210. For example, the stationary housing 220 may be disposed around a first portion of the heating jacket 210. The side surface of the fixing case 220 may be a flat surface of a rectangular shape. However, embodiments according to the present invention are not limited thereto, and for example, the stationary housing 220 may also have a curved surface.

The sealing cover pressing means 240 may include a vertical support bar 241, a horizontal bar (not shown), a first threaded bar 242, a first rotating handle 243, and a pressing plate 244. One end of the vertical support bar 241 may be connected to the fixed case 220, and the vertical support bar 241 may rotate with respect to the fixed case 220. The horizontal bar is connected to the other end of the vertical support bar 241 and extends in a direction perpendicular to the vertical support bar 241. The first threaded rod 242 may pass through a threaded hole in the horizontal rod. A first rotating handle 243 is connected to one end of the first threaded rod 242, and a pressing plate 244 may be connected to the other end. As shown in fig. 2, the sealing cover pressing means 240 may be rotated in the direction of arrow C to vertically overlap the sealing cover 230 during the operation of the gluing apparatus 200. The first rotating handle 243 is then rotated such that the first rotating handle 243 rotates in the direction of arrow a, thereby pushing the pressing plate 244 to move toward the sealing cover 230 (e.g., in the direction of arrow B) and press the sealing cover 230. Therefore, the sealing effect of the gluing apparatus 200 can be further improved by the sealing cover pressing means 240.

Glue barrel fastener 260 may include a second threaded rod 261 and a second rotating handle 262. The second threaded rod 261 may pass through threaded holes provided on the stationary housing 220 and the heating mantle 210 to contact the glue bucket 250. The second rotary handle 262 may be connected to an end of the second threaded rod 261 exposed to the outside of the stationary housing 220 for adjusting a fastening degree of the glue bucket 250. The glue barrel fastener 260 may be used to secure the glue barrel 250 to prevent the glue barrel 250 from wobbling during use.

The gluing device 200 can also include a platform connection bar 280 disposed on the stationary housing 220. The platform connecting rod 280 may be connected to the stationary housing 220 at a first end thereof and to a sliding platform (not shown) at the other end thereof. Therefore, the gluing device 200 can be driven by the sliding platform to perform linear motion or rotary motion, and can further perform gluing in different directions.

In addition, in accordance with another embodiment of the present invention, the nozzle 290 may be detachably connected to the fourth opening of the glue bucket 250. Specifically, as shown in fig. 3, the nozzle 290 may be detachably connected to the glue tub 250 by a nozzle connector 252. In this way, replacement and maintenance of the nozzle 290 may be further facilitated, and such a design may also avoid the problem of nozzle 290 becoming clogged during shutdown and restart.

According to the exemplary embodiment of the present invention, the above-mentioned gluing device can have a simple structure and a small size, thereby reducing the maintenance difficulty and the maintenance cost. Meanwhile, the gluing equipment can reduce the probability of poor gluing.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the following claims.
