[0029] See also Figure 1-Figure 7As shown, a switching variable-distance glue sticking device of the utility model comprises a movable carrier, two groups of suction cup units and a rotating driving component for driving the movable carrier to rotate around its axis. The two groups of suction cup units are respectively installed on the movable carrier, so that when the movable carrier rotates, each group of suction cup units is driven to pass through the glue taking station and the glue sticking station in sequence, and when one group of suction cup units arrives at the glue taking station to absorb the film, the other group of suction cup units arrives at the glue sticking station to perform the glue sticking action, thereby realizing the glue taking process and the glue sticking process to be carried out simultaneously. Specifically, the axis of the movable carrier is located in the up-down direction, and the two types of suction cup units are installed on the bottom surface of the movable carrier, and are separated into the left and right parts of the movable carrier with the axis of the movable carrier as the center line.

[0030] The two groups of suction cup units respectively include a plurality of suction cup components arranged along a preset direction and a variable distance driving component installed on a movable carrier, the variable distance driving component controls the spacing between adjacent suction cup components, and the spacing between adjacent suction cup components is different in the glue taking station and the glue applying station.

[0031] In the present embodiment, at least one of the plurality of suction cup components is configured to be movable in a preset direction, and the remaining suction cup components are fixedly mounted on the movable carrier, but not limited thereto. In other embodiments, the plurality of suction cup components are configured to be movable in a preset direction. The suction cup components movable in the preset direction are connected to the variable distance drive components in a one-to-one correspondence, so that the variable distance drive components drive the corresponding suction cup components to move in the preset direction to achieve variable distance. In the present embodiment, each group of suction cup units is respectively provided with two suction cup components, but the number of suction cup components of each group of suction cup units is not limited thereto. In other embodiments, each group of suction cup units includes three or more suction cup components. Among the two suction cup components of each group of suction cup units, one suction cup component is configured to be movable (i.e., movable in a preset direction), and the other suction cup component is configured to be fixed and fixed at the left or right end of the movable carrier. Therefore, each group of suction cup units includes a variable distance drive component.

[0034] In the present embodiment, the variable pitch drive component is a variable pitch cylinder 13, and the variable pitch cylinder 13 is a rodless cylinder. In other embodiments, the variable pitch drive component is a hydraulic cylinder or an electric push rod, etc. The movable carrier and / or the suction cup component fixedly mounted on the movable carrier is provided with a buffer located on the movement path of the variable pitch drive component, so as to buffer the variable pitch drive component. Since the variable pitch cylinder 13 is a rodless cylinder, the utility model is provided with buffers 12 on both sides of the movement path of the variable pitch cylinder 13, and the buffer 12 on one side is mounted on the first suction cup component 8 / the fourth suction cup component 11, and the buffer 12 on the other side is mounted on the movable carrier. In this way, when arriving at the glue taking station or the glue sticking station, the speed of the variable pitch cylinder 13 can be slowly reduced. The buffer 12 is specifically a hydraulic buffer, but is not limited to this.

The above two groups of suction cup units are respectively installed on the side of the supporting seat 4 facing away from the connecting seat 3 (i.e., the bottom surface of the supporting seat 4). The buffer 12 on the above movable carrier is installed at a position corresponding to the other side of the supporting seat 4 and the variable pitch cylinder 13.

[0036] In this embodiment, the support seat 4 is connected to the connecting seat 3 by a second guide mechanism, so that the second guide mechanism provides guidance for the movement of the support seat 4. The second guide mechanism specifically includes a plurality of second guide rails 6, each of which extends in the up and down directions, and each of which is movably inserted into a guide sleeve 7 fixed on the connecting seat 3, and the bottom end of each of which is connected to the support seat 4.

The elastic member 84 is pressed between the contour sucker 82 and the mounting seat 81, and the elastic member 84 can be implemented by a spring, but is not limited thereto. In this way, the contour sucker 82 can have a floating function, can be close to the rubber strip when taking the glue, and can avoid overpressure when applying the glue. An air path is provided inside the contour sucker 82, and a plurality of air holes are provided on the working surface of the contour sucker 82 (i.e., the bottom surface of the contour sucker 82) to absorb the film by vacuuming. A rubber pad 83 (the rubber pad 83 does not block the air hole) is provided on the working surface of the contour sucker 82 to prevent the contour sucker 82 from scratching the battery when applying the glue. The buffer 12 on the first sucker component 8 is installed on the mounting seat 81.

[0039] The third guide mechanism specifically includes a plurality of height-conforming screws 85 and a plurality of guide bearings 87. Each height-conforming screw 85 passes through a cover plate 86 and a guide bearing 87 provided in the mounting seat 81 in sequence, and is threadedly connected with the top of the contoured suction cup 82. In this way, not only is the guidance smooth, but the height position of the contoured suction cup can also be adjusted by using the height-conforming screw 85. The mounting seat 81 specifically consists of an upper and lower part connected by screws, and the cover plate 86 and the guide bearing 87 are respectively installed on the lower half of the mounting seat 81.

During operation, the telescopic cylinder 5 is driven to drive the support base 4 and the two groups of suction cup units thereon to move downward, so that the first suction cup component 8 and the second suction cup component 9 respectively arrive at the glue removal station and absorb the film. At the same time, the third suction cup component 10 and the fourth suction cup component 11 respectively arrive at the glue application station and adhere the absorbed film to the surface of the battery. Next, the telescopic cylinder 5 drives the support base 4 and the two groups of suction cup units thereon to rise, and the rotating cylinder is started, driving the entire movable carrier and the two groups of suction cup units thereon to rotate 180 degrees clockwise (such as Figure 6 As shown in the figure, the arrow in the figure indicates the rotation direction of the movable carrier), so that the two groups of suction cup units are exchanged; then, the variable pitch cylinders 13 of the two groups of suction cup units are started, so that the third suction cup component 10 located at the glue taking station is close to the fourth suction cup component 11 and is located above the glue taking station, and the second suction cup component 9 located at the glue sticking station is away from the first suction cup component 8 and is located above the glue sticking station, as shown in FIG.
