DETAILED DESCRIPTION

[0026] The present invention is now further described in conjunction with the accompanying drawings. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0027] like Figure 1 and Figure 5As shown, a glue sticking device includes a bracket 100 installed at the robot execution end, a film unloading mechanism 200 arranged at the middle of the right end of the bracket 100, a release paper receiving mechanism 300 arranged at the upper part of the left end of the bracket 100, and a film output mechanism 400 arranged at the lower part of the left end of the bracket 100, wherein the film output mechanism 400 includes a large swing arm 410, a power assembly 420, and an output assembly 430. The large swing arm 410 is arranged at the front side of the bracket 100, the right end of the large swing arm 410 is hinged to the bracket 100, and the left end thereof is connected to the power assembly 420, and the output assembly 430 is installed on the large swing arm 410. Through the setting of the film output mechanism 400, the glue surface of the output film faces upward, which is convenient for gluing the bottom of the power battery, and the film output is achieved without relying on the adhesive force of the glue surface itself, which belongs to active output of the film, thereby meeting the process requirements of gluing the bottom of the power battery. Specifically, the top of the bracket 100 is connected to the robot execution end through a connecting flange 900.

[0028] like Figure 5-Figure 7 As shown, the output assembly 430 includes a mounting plate 431, an output head 432 and a driving group 433. The mounting plate 431 is arranged at intervals in the middle of the front side of the large swing arm 410. The output head 432 is arranged between the large swing arm 410 and the mounting plate 431 and is located at the bottom of the large swing arm 410. A channel is provided in the output head 432 for the film to pass through. The driving group 433 is installed on the mounting plate 431 to drive the film on the film feeding mechanism 200 to be actively output by the output head 432. When outputting the film, the driving group 433 drives the film to move toward the output head 432, so that the film is output from the left end of the output head 432. Specifically, the bottom end of the mounting plate 431 is connected to the bottom end of the large swing arm 410 through a connecting block; the left end of the output head 432 is provided with an inclined surface 4321, and the inclined surface 4321 is located above the channel. The setting of the inclined surface 4321 is conducive to the separation of the isolation paper and the adhesive layer.

[0029] like Figure 5 and Figure 6 As shown, the driving group 433 includes a main roller 4331, a slave roller 4332 and a servo motor 4333. The main roller 4331 and the slave roller 4332 are rotatably arranged between the large swing arm 410 and the mounting plate 431, and are located on the right side of the output head 432. There is a gap between the main roller 4331 and the slave roller 4332 for the film to pass through. The servo motor 4333 is installed at the top of the mounting plate 431, and its output end is connected to the main roller 4331 by transmission. When outputting the film, the servo motor 4333 drives the main roller 4331 to rotate, thereby guiding the film in the gap to move. Since the servo motor 4333 can be precisely controlled, fixed-length glue can be achieved. Specifically, the output end of the servo motor 4333 is connected to the main roller 4331 through a belt and pulley structure, and the belt and pulley structure is a prior art.

[0030] like Figure 3 and Figure 5 As shown, the power assembly 420 includes a power cylinder 421, a pressure sensor 422 and a fisheye joint 423. The cylinder body of the power cylinder 421 is connected to the rotation of the bracket 100, and its driving end is connected to the rod end of the fisheye joint 423 through the pressure sensor 422. The bearing end of the fisheye joint 423 is connected to the upper left end of the large swing arm 410. Through the setting of the power assembly 420, the lifting and lowering of the left end of the large swing arm 410 is realized, which facilitates the subsequent shearing mechanism 800 to shear the film. The setting of the pressure sensor 422 is used to detect the change of force, so as to determine whether the film is cut.

[0031] like Figure 1 and Figure 2 As shown, the film unloading mechanism 200 includes a mounting shaft 210, a film material tray 220 and a magnetic powder brake 230. The mounting shaft 210 rotates through the bracket 100, one end of the mounting shaft 210 is connected to the film material tray 220, and the other end is connected to the magnetic powder brake 230. The magnetic powder brake 230 applies a force opposite to the rotation direction of the mounting shaft 210 to the mounting shaft 210, so that the film is always in a tensioned state. Specifically, a displacement sensor is provided at the top of the bracket 100 to detect whether the film on the film material tray 220 is used up.

[0032] like Figure 1 and Figure 2 As shown, the release paper receiving mechanism 300 includes a release paper receiving tray 310, a rotating shaft 320 and a reduction motor 330. The release paper receiving tray 310 is rotatably connected to the bracket 100 through the rotating shaft 320. The reduction motor 330 is mounted on the bracket 100, and its output end is transmission-connected to the rotating shaft 320. Specifically, the output end of the reduction motor 330 is connected to the rotating shaft 320 through a belt and a pulley structure; a displacement sensor is provided at the top of the bracket 100 to detect whether the release paper on the release paper receiving tray 310 is full.

[0033] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the gluing device further includes a pressing wheel 500 and a transition roller 600. The pressing wheel 500 is rotatably mounted on the upper left end of the large swing arm 410. There are a plurality of transition rollers 600 distributed on the bracket 100 and the large swing arm 410. The setting of the pressing wheel 500 guides the movement of the release paper.

[0034] like Figure 3 and Figure 4As shown, the glue sticking device also includes a tensioning mechanism 700, which includes a slider 710 and a spring 720. The slider 710 is slidably connected to the bracket 100, one end of the slider 710 is rotatably connected to the transition roller 600 on the bracket 100, and the other end is connected to one end of the spring 720, and the other end of the spring 720 is connected to the bracket 100. Through the setting of the tensioning mechanism 700, the film and the release paper are always in a tensioned state, further avoiding the film from being loosely wound on the film material tray 220, and also avoiding the release paper from being wound on the release paper receiving tray 310 in time. In addition, the setting of the spring 720 realizes the self-adaptation of the tension of the tensioning mechanism 700, avoiding excessive tension of the film and the release paper during the rotation of the large swing arm 410. Specifically, the tensioning mechanism 700 is respectively arranged between the film unwinding mechanism 200 and the film output mechanism 400 and between the release paper receiving mechanism 300 and the film output mechanism 400.

[0035] like Figure 1 and Figure 3 As shown, the adhesive laminating device further includes a shearing mechanism 800, which includes a slide cylinder 810 and a pneumatic scissors 820. The cylinder body of the slide cylinder 810 is connected to the lower left end of the bracket 100, and the pneumatic scissors 820 are installed at the driving end of the slide cylinder 810. The setting of the shearing mechanism 800 realizes the cutting of the film.

[0036] Before gluing, the film is loaded on the film material tray 220, and the leading edge of the film is pulled through the gap between the main roller 4331 and the slave roller 4332, and output from the left end of the output head 432. The isolation paper output from the left end of the output head 432 bypasses the pressure wheel 500 and is connected to the isolation paper receiving tray 310. When gluing, the robot drives the entire device to move until the lower side of the left end of the output head 432 slightly contacts the suction plate (not shown in the figure), and then the servo motor 4333 drives the main roller 4331 to rotate, and at the same time the robot drives the entire device to move along the gluing direction until the left end of the output head 432 outputs a fixed-length film, which is adsorbed by the suction plate. During this process, the reduction motor 330 drives the isolation paper receiving tray 310 to rotate to collect the isolation paper, and then the power cylinder 421 drives the left end of the large swing arm 410 to move upward, and the shearing mechanism 800 cuts the film, and a fixed-length rubber strip is formed on the suction plate. Finally, the power cylinder 421 drives the large swing arm 410 to reset. It should be noted that the reason why the drive group 433 is set to actively output the film is that the adhesive surface of the film output by this device faces upward, and the suction force provided by the suction plate is not enough to pull out the film, and it is also impossible to pull out the film by the adhesive force of the adhesive surface itself like a general gluing head.

[0037] The above-mentioned implementation mode is only for illustrating the technical concept and features of the utility model, and its purpose is to enable people familiar with this technology to understand the content of the utility model and implement it. It cannot be used to limit the protection scope of the utility model. All equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
