[0037] The bonding device in the existing barrel box assembly device often first sticks the barrel cover to the barrel box, and then sticks the surrounding strip on the barrel cover to strengthen the connection between the barrel cover and the barrel box. Because the whole process is completed in the barrel box, the whole process is limited by the barrel box space, resulting in higher production difficulty.

[0038] In view of this, the present invention provides a barrel-box assembly device, the barrel-box assembly device includes a bonding device, and any barrel-box assembly device including the bonding device belongs to the barrel-box assembly device mentioned in the present invention. Figures 1 to 4 This is an embodiment of the bonding device provided by the present invention.

[0039] See also Figure 1 to Figure 2 , a bonding device 100, including: a base 10, a first transport component, a first glue coating component and a second transport component. The base 10 is provided with a strip loading station, a cover plate loading station and a bonding station at intervals, and the strip loading station to the bonding station is from front to back, and the cover plate loading station to the bonding station is from left to right; the first transport component includes a first transport member movably arranged on the base 10 along the front-back direction, and the first transport member is used to transport the strip 200 from the strip loading station to the bonding station; the first gluing component is arranged between the strip loading station and the bonding station, and the first gluing component is used to spray glue on the upper end surface of the strip 200 passing through; the second transport component includes a second transport member movably arranged on the base 10 along the left-right direction, and the second transport member is used to transport the cover plate 300 from the cover plate loading station to the bonding station, so that the cover plate 300 is bonded to the upper end surface of the strip 200, so that the box body can subsequently install the cover plate 300.

[0040] In the present invention, the front-to-back direction is the relative direction between the strip loading station and the bonding station, wherein the direction of the strip loading station is the front; the left-right direction is the relative direction between the cover plate loading station and the bonding station, wherein the direction of the cover plate loading station is the left; the up-down direction is the relative direction between the cover plate 300 and the strip 200 located at the bonding station, wherein the relative direction of the cover plate 300 is upward.

[0041] In the present invention, the cover plate 300 bonded by the bonding device 100 has a main surface and a bonding surface that are oppositely arranged, wherein the main surface is arranged upward.

[0042] In the technical solution of the present invention, the bonding device 100 transports the strip 200 backward from the strip loading station to the bonding station, and transports the cover plate 300 rightward from the cover plate loading station to the bonding station, thereby transporting the strip 200 and the cover plate 300 to the bonding station from different directions, and then the strip 200 and the cover plate 300 are bonded at the bonding station located on the base 10, thereby achieving the effect of bonding the strip 200 and the cover plate 300 on the outside of the barrel box. Specifically, the bonding device 100 is provided with a first transport component to transport the fence 200, and a second transport component to transport the cover plate 300, and the first transport component and the second transport component both have a movement stroke toward the bonding station, wherein the fence 200 will pass through the first gluing component disposed between the fence loading station and the bonding station during transportation, and the first gluing component sprays glue on the upper end surface of the fence 200 to form a combination of the cover plate 300 and the fence 200 glued together, and this combination can be assembled as a whole into the barrel box mouth to form a barrel box finished product. The bonding device 100 proposed by the present invention transports the fence 200 and the cover plate 300 to the bonding station from different directions for bonding, and the fence 200 and the cover plate 300 are bonded outside the barrel box, which greatly reduces the difficulty of assembling the fence 200, barrel cover and other parts of the barrel box.

[0043] What needs to be said about the first glue coating component is that the first glue coating component is provided with a glue spraying nozzle, and the glue spraying nozzle is arranged toward the transportation path of the enclosure 200. When the enclosure 200 is transported to the glue spraying position of the glue spraying nozzle, the glue spraying nozzle sprays glue on the upper end surface of the enclosure 200. The first glue coating component is used to apply glue to the enclosure 200, but the first glue coating component can also apply glue to the cover plate 300 or to both the cover plate 300 and the enclosure 200, as long as the enclosure 200 and the cover plate 300 can be bonded. The specific structural composition of the first glue coating component will not be specifically described here, as long as it can spray glue on the enclosure 200.

[0044] For further information, see Figures 1 to 3 The bonding device 100 includes a transfer platform 14 mounted on the base 10, and a material transport channel 13 extending from the strip loading station to the bonding station is provided in the middle of the transfer platform 14, and the material transport channel 13 is arranged to penetrate in the up-down direction; the first transport member includes a first suction cup 20 for being movably arranged in the direction of approaching and moving away from the strip loading station, and a driving cylinder 21 for driving the first suction cup 20, and the driving cylinder 21 is telescopically arranged toward the material transport channel 13, and the driving cylinder 21 is used to The first suction cup 20 is driven to extend into the material transport channel 13 to approach the surrounding strip 200, and the first suction cup 20 is used to absorb the surrounding strip 200 when approaching the surrounding strip 200; the first suction cup 20 is movably arranged in the front-to-back direction to reciprocate between the surrounding strip loading station and the bonding station, and the first transport component also includes a driving member 22 for driving the first suction cup 20 to move forward and backward, so that when the first suction cup 20 picks up the surrounding strip 200, it drives the surrounding strip 200 to move to the bonding station.

[0045] In this embodiment, the first suction cup 20 has a movement stroke approaching and moving away from the bar loading station under the drive of the driving cylinder 21, wherein when the first suction cup 20 approaches the bar loading station, the first suction cup 20 naturally approaches the bar 200 on the bar loading station and picks up the bar 200, and the driving member 22 can also drive the first suction cup 20 to move in the front-back direction, so that the first suction cup 20 can be driven from the bar loading station to the bonding station, and then the bar 200 picked up by the first suction cup 20 is also driven to the bonding station to wait for bonding. In this way, the transportation process of the bar 200 from the bar loading station to the bonding station is realized, and the first transportation component can transport the bar 200 to the bonding station in sequence and in an orderly manner, and the transportation efficiency is relatively high.

[0046] The transfer platform 14 is provided with the material transport channel 13 which runs through in the up-down direction, and when the fence 200 is located at the fence loading station, a part of it must be located above the material transport channel 13, and when the first suction cup 20 is driven by the driving cylinder 21 to extend into the material transport channel 13, the first suction cup 20 absorbs the fence 200 located above the material transport channel 13. The first suction cup 20 moves toward the bonding station driven by the driving member 22, thereby transporting the fence 200 absorbed by it to the bonding station. The first transport member is arranged below the material transport channel 13, so when the first transport member transports the fence 200, the first transport member does not interfere with other structures on the transfer platform 14, and the fence 200 can be transported relatively smoothly.

[0047] In this embodiment, the first suction cup 20 is used to suck the surrounding strip 200, which has a smaller force on the surrounding strip 200 and can reduce the loss of the surrounding strip 200 to a certain extent.

[0048] Regarding the linkage member 23, it should be noted that the linkage member 23 can be a plate-like structure set as a linkage plate, or a rod-like structure set as a linkage rod, and the linkage member 23 only needs to be able to connect the two first transport members. Regarding the driving member 22, it should be noted that the driving member 22 can be a cylinder or a motor, as long as the driving member 22 can drive the first suction cup 20. Regarding the driving cylinder 21, in this embodiment, the driving cylinder 21 is selected to drive the first suction cup 20, but it does not mean that only the driving cylinder 21 can drive the first suction cup 20. It can also be a motor, as long as it can drive the first suction cup 20.

[0049] Furthermore, the first transport component includes two first transport members and a linkage member 23 which are arranged in sequence along the front-to-back direction, the linkage member 23 is used to connect the two first transport members, and the linkage member 23 is movably installed on the base 10 along the front-to-back direction; the driving member 22 is drivingly connected to the linkage member 23, so that when the first transport member located on the front side moves to the strip loading station and the first transport member located on the rear side moves to the bonding station, the linkage member 23 is driven to move backward, so that the first transport member located on the front side is reset to the bonding station.

[0050] In this embodiment, the linkage member 23 and the two first transport members are both movably arranged in the front-back direction, and the linkage member 23 is used to connect the two first transport members, so that when the linkage member 23 moves in the front-back direction, the two first transport members will be driven to move together. When the first transport member located at the front side is located at the enclosure strip loading station and the first transport member at the rear side is located at the bonding station, the linkage member 23 performs a front-back reciprocating motion under the drive of the driving member 22, so that the first transport member located at the front side transports a enclosure strip 200 to the bonding station, and in the next reciprocating stroke, the enclosure strip 200 is transported from the bonding station to the rear by the first transport member at the rear side after the bonding is completed, so as to realize uninterrupted continuous processing.

[0051] Further, see Figure 1 to Figure 2 The bonding device 100 also includes two groups of limit blocks 12, which are respectively arranged above the bonding station and the enclosure strip loading station. The two groups of limit blocks 12 are used to limit the enclosure strip 200 from upwardly detaching from the bonding station and the enclosure strip loading station when the first suction cup 20 extends into the material transport channel 13.

[0052] In this embodiment, the first suction cups 20 on the two first transport members suck the enclosure strips 200 at the enclosure strip loading station and the bonding station respectively. When the first suction cups 20 are driven by the driving cylinder 21 to extend into the material transport channel 13, the second suction cups 30 may come into direct contact with the enclosure strips 200, and may push the enclosure strips 200 upwards out of position. Therefore, it is necessary to restrict the enclosure strips 200 from upwardly separating from the bonding station and the enclosure strip loading station. Therefore, a set of limit blocks 12 are provided above the bonding station and the enclosure strip loading station to prevent the enclosure strips 200 from deviating from the preset position.

[0053] For further information, see Figure 1 and Figure 3 The second transport component also includes a first driver 31 and a second suction cup 30 that is movable in the left and right directions and is arranged above the cover plate loading station. The second suction cup 30 is used to adsorb the main surface of the cover plate 300. The first driver 31 is driven and connected to the second suction cup 30 so that when the second suction cup 30 adsorbs the cover plate 300, the second suction cup 30 is driven to move from left to right to the bonding station to bond the back side of the cover plate 300 to the upper end surface of the surrounding strip 200.

[0054] In this embodiment, the second suction cup 30 is used to adsorb the cover plate 300, and the second suction cup 30 needs to transport the cover plate 300 to the bonding station, and the first driver 31 is used to drive the second suction cup 30 to move left and right to the bonding station when the second suction cup 30 adsorbs the cover plate 300, so that the cover plate 300 adsorbed by the second suction cup 30 is bonded to the upper end surface of the surrounding strip 200 from top to bottom.

[0055] What needs to be mentioned about the first driver 31 is that the first driver 31 can be a cylinder or a motor, as long as the first driver 31 can drive the second suction cup 30 .

[0056] For further information, see Figure 3 The second transport component also includes a pressing block 32 movably arranged along the up-down direction, and the pressing block 32 is used to abut against the bonding section 310 of the cover plate 300 when the second suction cup 30 absorbs the cover plate 300, and when the second suction cup 30 moves to the bonding station, the pressing block 32 moves from top to bottom toward the surrounding strip 200 to press the bonding section 310 of the cover plate 300 on the upper end surface of the surrounding strip 200.

[0057] In this embodiment, the pressing block 32 is arranged on one side of the second suction cup 30, so that when the second suction cup 30 sucks the cover plate 300, the pressing block 32 naturally abuts against the bonding section 310 of the cover plate 300, and when the second suction cup 30 moves to the bonding station, the bonding section 310 of the cover plate 300 is located above the middle of the surrounding strip 200, and at this time, the pressing block 32 presses the bonding section 310 of the cover plate 300 downward onto the upper end surface of the surrounding strip 200, thereby completing the bonding. The pressing block 32 can make the bonding more complete and the bonding firmness better.

[0058] For further information, see Figure 1 , Figure 2 and Figure 4 The bonding device 100 further includes a guide rod 11 disposed on the base 10 , wherein the guide rod 11 extends backward from the bonding station, and the guide rod 11 is used to support the cover plate 300 .

[0059] In this embodiment, the cover plate 300 has a main surface facing upward and an adhesive surface facing downward. In the specific production process, there are different types of the cover plate 300, one of which has a blister 320 protruding downward in the middle of the adhesive surface of the cover plate 300, and the blister 320 is in the shape of a ring. When the cover plate 300 is bonded to the surrounding strip 200, the bonding section 310 of the cover plate 300 is bonded to the middle of the surrounding strip 200, and the opposite side of the bonding section 310 of the cover plate 300 is extended outward from the surrounding strip 200. The blister 320 is set downward at this time, that is, the blister 320 may interfere with the base 10. In this embodiment, the base 10 is not used to carry the protruding part of the cover plate 300, but a guide rod 11 is provided to carry the cover plate 300. The guide rod 11 is extended from the bonding station toward the rear, so that when the cover plate 300 is transported to the next process after the bonding is completed, the guide rod 11 can always carry the cover plate 300 during this transportation process, and the blister 320 is located in the gap between the base 10 and the guide rod 11, thereby avoiding the interference between the blister 320 and the base 10. The provision of the guide rod 11 can avoid increasing the occupied space of the base 10, and the use of the guide rod 11 to carry the cover plate 300 can reduce the possibility of interference between the base 10 and other structures, and the bearing effect is also good, so that barrel boxes of different box types can be processed.

[0060] In another embodiment of the present invention, the guide rod 11 is arranged on the upper side of the bonding station. Because when the guide rod 11 is arranged on the left and right sides of the bonding station, the size of the cover plate 300 requires the guide rod 11 to be farther away from the bonding station, while being arranged on the upper side of the guide rod 11 can make the guide rod 11 closer to the bonding station, thereby reducing the space occupied by the bonding device 100.

[0061] Furthermore, the bonding device 100 further includes a second glue coating component (not shown), which is disposed at the bonding station and is used for spraying glue on the upper end surface of the cover plate 300 passing through.

[0062] In this embodiment, after the cover plate 300 is bonded to the surrounding strip 200, part of the glue-coated area on the surrounding strip 200 is covered by the cover plate 300, so it is necessary to fill the glue on this part for use when the combination of the cover plate 300 and the surrounding strip 200 is subsequently assembled on the box mouth of the barrel box. The second glue-coating component is provided with a glue spraying nozzle, which is arranged toward the transportation path of the cover plate 300. When the cover plate 300 is transported to the glue spraying position of the glue spraying nozzle, the glue spraying nozzle sprays glue on the upper end surface of the cover plate 300. The specific structural composition of the second glue-coating component will not be specifically described here, as long as it can apply glue to the cover plate 300.

[0063] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
