Description

Technical Field

[0001] This utility model relates to the field of labeling equipment technology, and in particular to an automatic four-sided labeling machine. Background Technology

[0002] Currently, there are many types of automatic labeling machines on the market, but most can only perform single-sided or double-sided labeling. For products requiring four-sided labeling, multiple labeling processes are usually used. This method not only increases production costs and manual operation difficulty, but may also lead to problems such as inaccurate label placement and loose label adhesion. For example, taking battery packaging as an example, traditional soft-pack batteries usually require four-sided labeling, but traditional single-sided or double-sided labeling equipment usually cannot meet the requirements of four-sided labeling for soft-pack batteries. Therefore, the labeling of traditional soft-pack batteries mostly relies on manual or semi-automated processes, but this labeling method is not only inefficient, but also has low labeling accuracy.

[0023] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be given below with reference to the accompanying drawings.

[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, an automatic four-sided labeling machine 10 includes: a feeding component 100, a label picking component 200, a labeling component 300, and a discharging component 400. The feeding component 100 includes a feeding robot 110; the label picking component 200 includes a label picking robot 210; the labeling component 300 includes a product transfer device 310, a front rolling device 320, and a label wrapping device 330. The product transfer device 310 is sequentially provided with a feeding area, a front rolling area, and a label wrapping area. The front rolling device 320 is located on the front rolling area, and the label wrapping device 330 is located on the label wrapping area. The product transfer device 310 is provided with a positioning transfer platform 311; the positioning... When the transfer platform 311 is located in the unloading area, the feeding robot 110 is used to transport the product to the positioning transfer platform 311, the label picking robot 210 is used to transport the label and attach it to the front of the product, the positioning transfer platform 311 is used to transfer the labeled product from the unloading area to the front rolling area and the label wrapping area respectively, the front rolling device 320 is used to roll the front of the labeled product, and the label wrapping device 330 is used to wrap the label to the two sides and the back of the product; the unloading component 400 includes an unloading robot 410, which is used to transport and unload the labeled product on the label wrapping device 330.

[0025] It should be noted that, taking a soft-pack battery as an example, when labeling the battery, the positioning and transfer platform 311 first moves to the feeding area. The feeding robot 110 then transports the battery onto the positioning and transfer platform 311. Next, the label-removing robot 210 transports and affixes the label to the front of the battery on the positioning and transfer platform 311. At this point, the label size is larger than the front of the battery, meaning the label extends away from the battery on both sides, resembling wings, to facilitate subsequent labeling operations on the sides and back. Then, the positioning and transfer platform 311 transfers the tagged battery through the front rolling area, where the front rolling device 320 rolls the battery on the front rolling area. A rolling operation is performed on the front side to ensure the label adheres firmly to the front of the battery. In this embodiment, to ensure the accuracy of the stopping position of the positioning and transfer platform 311, a photoelectric sensor can be installed on the front rolling area. The photoelectric sensor identifies whether the positioning and transfer platform 311 has moved to the front rolling area, thereby controlling the accuracy of the stopping position of the positioning and transfer platform 311 and improving the degree of automation. After the front rolling operation is completed, the positioning and transfer platform 311 continues to transfer the battery to the label wrapping area. Through the label wrapping device 330, in conjunction with the positioning and transfer platform 311 and the unloading robot, the extended labels on both sides are wrapped onto the two sides and the back of the battery respectively. In this way, manual intervention can be reduced to achieve labeling operation on all four sides of the battery, thereby improving labeling efficiency and labeling accuracy.

[0026] In one embodiment, to further improve the automation level of the automatic four-sided labeling machine, the feeding assembly 100 also includes a feeding belt conveyor 120, which is located on the side near the feeding robot 110. The feeding belt conveyor 120 is used to continuously transport batteries to the picking area of ​​the feeding robot 110, so as to facilitate continuous picking by the feeding robot 110, reduce standby time, and improve labeling efficiency. Similarly, the discharging assembly 400 also includes a discharging belt conveyor 420, which is located on the side near the discharging robot 410. The discharging belt conveyor 420 is used to continuously transport the batteries that have completed the labeling operation to the next station, so as to facilitate continuous discharging by the discharging robot 410, avoid battery accumulation, and improve the automation level. In this embodiment, both the feeding robot 110 and the discharging robot 410 can be existing three-axis robots. At the same time, the gripping part of the robot is a vacuum suction nozzle structure, which can reduce damage to the battery and ensure the yield rate of the battery.

[0027] In one embodiment, to further enhance the automation of the automatic four-sided labeling machine, the label-taking component 200 also includes a label feeding device 240 and a label dispensing platform 220. The label feeding device 240 is located near the label-taking robot 210, and the label dispensing platform 220 is located between the label-taking robot 210 and the label feeding device 240. A paper-peeling blade 230 is provided on the label feeding device 240, facing the label dispensing platform 220. The label feeding device 240 continuously feeds labels to the label dispensing platform 220, and the paper-peeling blade 230 tears the labels from the release film. Simultaneously, the label-taking robot 210 adsorbs and fixes the labels on the label dispensing platform 220 and transports them to the front of the battery on the positioning and transfer platform 311. At this time, the labels are on the battery, in a flapped-wing state. In this embodiment, the label-taking robot 210 is a three-axis robot, and the label-taking end is a vacuum suction nozzle structure.

[0028] To further improve the accuracy of labeling position, the automatic four-sided labeling machine 10 also includes a CCD camera detection device 500. The CCD camera detection device 500 is located below the label-picking end of the label-picking robot 210. After the label-picking robot 210 completes label picking, it first passes through the CCD camera detection device 500 to detect the position of the label and transmits the signal to the control terminal. The control terminal controls the label-picking robot 210 to adjust the label position, that is, to perform positioning compensation for the label position. Then, the label-picking robot 210 affixes the label to the front area of ​​the battery on the positioning and transfer platform 311.

[0029] In one embodiment, the product transfer device 310 includes a mounting frame 312 and a linear drive module 313. The mounting frame 312 has a clearance area, and guide rails are provided on both sides of the clearance area. A positioning transfer platform 311 is slidably mounted on the guide rails. The linear drive module 313 is connected to the positioning transfer platform 311 and is used to drive the positioning transfer platform 311 to reciprocate in the feeding area, the front rolling area, and the label wrapping area. The clearance area extends along the direction of the guide rails to facilitate the movement and clearance of the positioning transfer platform 311. The guide rails on the mounting frame 312 further ensure the stability of the positioning transfer platform 311's movement.

[0030] In one embodiment, the positioning and transfer platform 311 includes a transfer frame 311a, a positioning component 311b, and a lifting loading component 311c. The transfer frame 311a has a lifting clearance hole, and the lifting loading component 311c passes through the lifting clearance hole and the clearance area, respectively. The positioning component 311b is arranged around the lifting clearance hole. A linear drive module 313 is connected to the transfer frame 311a and is used to drive the transfer frame 311a to reciprocate in the feeding area, the front rolling area, and the label wrapping area. When a battery with a label is placed on the lifting loading component 311c, the lifting loading component 311c descends and positions the battery through the positioning component 311b to ensure the accuracy of the battery's position. Then, the transfer frame 311a drives the positioning component 311b and the lifting loading component 311c to the front rolling area for the front label rolling operation, and finally, it is transferred to the label wrapping area for the label wrapping operation.

[0031] Furthermore, the transfer frame 311a includes a transfer carrier plate and a fixing plate. The transfer carrier plate is located above the mounting frame 312. One end of the fixing plate is disposed on the bottom surface of the transfer carrier plate, and the other end of the fixing plate passes through the clearance area. The linear drive module 313 is connected to the fixing plate, and the fixing plate is moved by the linear drive module 313. In this embodiment, the linear drive module 313 can be a servo motor ball screw structure. The servo motor ball screw structure is an existing drive structure and will not be described in detail here.

[0032] In one embodiment, the positioning component 311b includes a first positioning block, a second positioning block, a first positioning cylinder, and a second positioning cylinder. The first positioning block, the second positioning block, the first positioning cylinder, and the second positioning cylinder are arranged around a lifting clearance hole, with the first positioning block and the first positioning cylinder facing each other, and the second positioning block and the second positioning cylinder facing each other. The positions of the first and second positioning blocks are fixed. The position of the battery on the positioning and transfer platform 311 is adjusted by moving the first and second positioning cylinders, thereby ensuring the accuracy of the battery's position.

[0033] In one embodiment, the lifting loading component 311c includes an adsorption loading structure, a lifting extension plate, and a lifting drive structure. The lifting extension plate passes through lifting clearance holes and clearance areas. The adsorption loading structure is located on one end of the lifting extension plate above the mounting frame 312. The lifting drive structure is connected to the lifting extension plate and is used to drive the lifting extension plate to perform reciprocating lifting motion, thereby enabling the adsorption loading structure to achieve reciprocating lifting motion. The adsorption loading structure includes a suction plate and a vacuum locking block. The suction plate is connected to the vacuum locking block, and the suction plate is used to adsorb and fix the battery. The vacuum locking block is used to connect to a vacuum pumping device.

[0034] In one embodiment, the front rolling device 320 includes a front rolling fixing frame 321, a slide cylinder 322, and a front rolling component 323. The front rolling fixing frame 321 is installed on the front rolling area of ​​the product moving device, the slide cylinder 322 is installed on the front rolling fixing frame 321, and the front rolling component 323 is connected to the slide cylinder 322. When the positioning and transfer platform 311 moves to the front rolling area, the slide cylinder 322 is used to drive the front rolling component 323 to move towards or away from the positioning and transfer platform 311. In this embodiment, the front rolling component 323 includes a lifting sliding plate, a front roller, and a roller connecting frame. The lifting sliding plate is disposed on the drive end of the slide cylinder 322, the roller connecting frame is slidably disposed on the lifting sliding plate, and the front roller is mounted on the roller connecting frame. The roller connecting frame is connected to the lifting sliding plate through a buffer spring rod. In this way, the rolling operation of the front roller is buffered by the buffer spring rod, thereby avoiding damage to the battery caused by the front roller, and thus improving the yield of the battery. At the same time, the front rolling device 320 can ensure the tight adhesion between the label and the front of the battery.

[0035] In one embodiment, the labeling device 330 includes a label fixing frame 331, a lower rolling element 332, and an upper rolling element 333. The label fixing frame 331 is installed on the label wrapping area of ​​the product transfer device 310. The lower rolling element 332 and the upper rolling element 333 are respectively disposed on the label fixing frame 331, and the upper rolling element 333 is located above the lower rolling element 332. The lifting loading element 311c drives the product with the label attached to pass through the lower rolling element 332 and the upper rolling element 333 respectively, so that the label is wrapped to the two sides and the back of the product. When the lifting loading component 311c moves the battery with the label attached to the lower rolling component 332, the lower rolling component 332 rolls the double wings of the label on the battery to both sides of the battery. The lifting loading component 311c continues to move the battery upward. At this time, the unloading robot 410 moves simultaneously, adsorbs the front of the battery, and removes the battery from the lifting loading component 311c. While the unloading robot 410 is unloading the battery, it passes through the upper rolling component 333. The battery is located between the unloading robot 410 and the upper rolling component 333. During the movement of the unloading robot 410, it pushes the battery label against the upper rolling component 333, so that the upper rolling component 333 rolls the label on one or both sides of the battery, thereby attaching the label on one or both sides of the battery to the back of the battery. In this way, the labeling operation on all four sides of the battery is achieved.

[0036] In one embodiment, the lower rolling element 332 includes a first elastic roller and a second elastic roller, which are respectively disposed opposite to each other on the label fixing frame 331. The lifting loading element 311c is located between the first elastic roller and the second elastic roller. A spring is provided on the first elastic roller. When the lifting loading element 311c moves the battery through the lower rolling element 332, the spring is in a compressed state, which plays a buffering role and ensures the tightness of the label and the battery. The first elastic roller and the second elastic roller have the same structure and cooperate with each other to attach the label to both sides of the battery.

[0037] In one embodiment, the upper roller pressing component 333 includes a first roller and a second roller arranged opposite to each other. When the unloading robot 410 moves the battery to the upper roller pressing component, the upper roller pressing component affixes the battery label to the back of the battery, thereby completing the four-sided labeling operation of the battery.

[0038] In one embodiment, an adjustment structure 331a is also provided on the label fixing frame 331. The adjustment structure 331a is used to adjust the relative positions of the first elastic roller and the second elastic roller, as well as the relative positions of the first roller and the second roller, so as to match the labeling operation of soft-pack batteries of different specifications and sizes and improve the labeling versatility of the automatic four-sided labeling machine.

[0039] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
