Description

Technical Field

[0001] This invention relates to the field of lithium battery packaging, and more particularly to a lithium battery packaging device with positioning function. Background Technology

[0002] After lithium batteries are processed and packaged, labels need to be affixed to their surfaces to facilitate identification of genuine and model information by personnel or users. During the labeling process, labels are prone to wrinkling, leading to uneven adhesion and affecting the overall labeling effect. Chinese patent application number CN202110778278.1 describes a fully automatic flat labeling machine that, when labeling large items, first uses a label-pulling mechanism to firmly adhere and tighten the front and back ends of the label. To prevent wrinkles at the top of the label, the label is designed to adhere smoothly to the top of the labeling unit. When the labeling unit moves to the labeling position, the label-pulling mechanism slowly rolls off the label. In conjunction with the limiting mechanism, rotating mechanism, and leveling mechanism, the label is smoothly adhered to the top of the labeling unit during the rightward conveying process. This ensures the flatness of large labels during labeling and prevents wrinkles and air bubbles from forming on them. However, the label-pulling mechanism of this device can only solve the problem of longitudinal wrinkles on the label and cannot solve the problem of transverse wrinkles.

[0003] Meanwhile, if horizontal wrinkles are detected after the label is affixed, the affixed label needs to be torn off, flattened, and then re-attached. During the process of tearing the affixed label off the battery, the sides of the label are prone to breakage or bending, which means that the label cannot be completely and neatly attached to the battery during the re-attachment process, reducing the labeling yield. Summary of the Invention

[0004] To overcome the shortcomings of existing equipment that can only solve longitudinal wrinkles in the label tightening process but cannot solve the problem of lateral wrinkles, and that if lateral wrinkles are detected after labeling, the label needs to be torn off, flattened, and re-attached, and that the label is prone to breakage or bending on both sides during the tearing process, resulting in the label not being able to be completely and neatly attached to the battery during re-attachment, thus reducing the labeling yield, this invention provides a lithium battery packaging device with positioning function.

[0005] The technical solution is as follows: A lithium battery packaging device with positioning function includes a roller conveyor, a first mounting frame, and a labeling machine; the roller conveyor is equipped with the first mounting frame; the first mounting frame is equipped with a labeling machine for labeling lithium batteries; it also includes a detection unit, a gripper, a compression block, and a label protection system; the first mounting frame is equipped with a detection unit for identifying whether the label has bubbles or wrinkles, and the detection unit is located to the right of the labeling machine; the labeling machine is equipped with a label feeding port; the label feeding port is equipped with a gripper for holding the label; a compression block that moves left and right to flatten the label is located to the left of the detection unit, and the compression block is located to the right of the gripper; the compression block is equipped with an inclined surface for guiding the label feeding port to move upward; the compression block is equipped with a label protection system to prevent the label from breaking on both sides.

[0006] As a further preferred embodiment, the detection unit includes a second mounting bracket and an electronic eye; the second mounting bracket is fixedly attached to the first mounting bracket; an electronic eye for identifying whether the label has bubbles or wrinkles is provided on the left side of the second mounting bracket.

[0007] As a further preferred embodiment, it also includes a first driving member; the first driving member is mounted on the left side of the second mounting bracket; and the driving end of the first driving member is fixedly connected to the extrusion block.

[0008] As a further preferred embodiment, the label protection system includes protective blocks; one protective block is fixed to the front side and the rear side of the compression block.

[0009] As a further preferred option, the protective block is provided with a guide surface.

[0010] As a further preferred embodiment, an electrically operated telescopic plate is also included; without using the compression block, the drive end of the first drive member is fixedly connected to the electrically operated telescopic plate, and the front and rear sides of the electrically operated telescopic plate are respectively fixedly connected to the adjacent protective blocks.

[0011] As a further preferred option, it also includes a heating element; a heating element is installed on the right side of the clamp.

[0012] As a further preferred option, a glue applicator is also included; the glue applicator is mounted on the first mounting bracket.

[0013] As a further preferred option, the glue applicator is equipped with several glue application nozzles, and the glue application nozzles are inclined to the lower right.

[0014] As a further preferred option, the protective block is provided with a cleaning surface.

[0015] The present invention has the following advantages: When the extrusion block moves rapidly to the left to below the label feeding port, the inclined surface guides the label feeding port upward to fit with the clamp, thereby fixing the label on the label feeding port;

[0016] The upward movement of the label feeding port driven by the extrusion block stretches the label, which helps to smooth out horizontal wrinkles on the label and improve the labeling yield.

[0017] When the lithium battery is transferred to the extrusion block, the extrusion block presses the label together, enhancing the adhesion of the label to the lithium battery and achieving re-adhesion of the label.

[0018] During the label tearing process, the front and back sides of the label are pre-treated by the protective block, which causes the front and back sides of the label to bend upwards to prevent the front and back sides of the label from breaking, thus protecting the label.

[0019] During the label peeling process, the electric telescopic plate expands the label to the front and back sides, which helps to smooth out the longitudinal wrinkles on the label and improve the labeling yield.

[0020] During the label re-tearing process, the label is preheated by an electric heating element to melt the adhesive underneath, which facilitates the re-tearing process. At the same time, the preheating of the label by the electric heating element prevents the label from delaminating during the re-tearing process, thus protecting the label.

[0021] During the label re-application process, glue is sprayed onto the lithium battery using a glue applicator to prevent insufficient adhesion of the label during re-application, ensuring a high yield rate for the labeling process. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0036] Example 1

[0037] like Figures 3-9 As shown, a lithium battery packaging device with positioning function includes a roller conveyor 1, a first mounting frame 2, and a labeling machine 3; the roller conveyor 1 is provided with the first mounting frame 2; the first mounting frame 2 is provided with the labeling machine 3.

[0038] It also includes a detection unit, a gripper 4, a compression block 5, and a label protection system; the detection unit is located on the front side of the first mounting frame 2, and the detection unit is located to the right of the labeling machine 3; the labeling machine 3 is provided with a label feeding port 3001; the gripper 4 is provided on the label feeding port 3001; the compression block 5 is provided on the left side of the detection unit, and the compression block 5 is located to the right of the gripper 4; the compression block 5 is provided with an inclined surface 5001; firstly, the label is transferred to the label feeding port 3001 through the labeling machine 3, and at the same time, the roller conveyor 1 drives the lithium battery to be transferred from left to right. When the label on the labeling port 3001 contacts the upper surface of the lithium battery, the label is adhered to the upper surface of the lithium battery through the cooperation of the roller conveyor 1 and the labeling machine 3. When the detection unit detects air bubbles or wrinkles in the label already adhered to the upper surface of the lithium battery, the roller conveyor 1 reverses the transport, moving the lithium battery from right to left. At the same time, the extrusion block 5 moves rapidly to the left to below the labeling port 3001, and guides the labeling port 3001 upward through the inclined surface 5001 until it is in contact with the clamp 4, thus clamping and fixing the label on the labeling port 3001 and preventing... To prevent label movement, when the lithium battery moves from right to left, the label on the label feeding port 3001 is clamped and fixed and cannot move. At this time, the label already attached to the upper surface of the lithium battery is torn off, achieving label re-tear. Then, when the extrusion block 5 drives the label feeding port 3001 to move upward, the pulling force generated on the label achieves flattening and smoothing of the label, which helps to smooth out the horizontal wrinkles on the label and improve the labeling yield. After the label re-tear is completed and the wrinkles on the label are smoothed, the roller conveyor 1 transports the lithium battery in the forward direction, moving it from left to right. Simultaneously, the extrusion block 5 moves rapidly to the right to reset, resetting the label feeding port 3001, thereby allowing the label to be normally transported and adhered to the upper surface of the lithium battery. When the lithium battery is transported to the area below the extrusion block 5, the label is pressed against the lower surface of the extrusion block 5, enhancing the adhesion of the label to the lithium battery and achieving re-adhesion of the label. The extrusion block 5 is equipped with a label protection system. During the label tearing process, the label protection system pre-processes the front and back sides of the label, causing the sides of the label to bend upwards to prevent breakage and improve the yield of the labeled product.

[0039] The detection unit includes a second mounting bracket 101 and an electronic eye 103; the second mounting bracket 101 is fixedly connected to the front right side of the first mounting bracket 2; the electronic eye 103 is provided on the left side of the second mounting bracket 101; the electronic eye 103 identifies whether there are bubbles or wrinkles on the affixed label.

[0040] It also includes a first driving component 102; the first driving component 102 is installed on the left side of the second mounting bracket 101, and the first driving component 102 is an electric push rod; and the driving end of the first driving component 102 is fixedly connected to the extrusion block 5; the extrusion block 5 is moved left and right by the first driving component 102.

[0041] It also includes a second driving component 104 and a limiting block 105; the front side of the roller conveyor 1 is equipped with a second driving component 104 for pushing the lithium battery, and the second driving component 104 is an electric push rod; the rear side of the roller conveyor 1 is equipped with a limiting block 105 for positioning the lithium battery; when the lithium battery is transported from left to right on the roller conveyor 1, the second driving component 104 pushes the lithium battery to move from front to back to the bonding limiting block 105, so that the lithium battery is located below the label feeding port 3001, thereby realizing the positioning function for labeling.

[0042] The label protection system includes a protective block 201; a protective block 201 is fixed to the front and rear sides of the compression block 5; during the label tearing process, the protective blocks 201 pre-treat the front and rear sides of the label, causing the front and rear sides of the label to bend upwards, preventing the front and rear sides of the label from breaking, thus protecting the label.

[0043] The protective block 201 is provided with a guide surface 20101; during the label tearing process, the guide surface 20101 causes the front and back sides of the label to bend upwards at an angle, preventing creases from forming on the front and back sides of the label due to excessive bending angle during the bending process, thus protecting the label.

[0044] Example 2

[0045] Based on Example 1, such as Figures 7-11 As shown, it also includes an electric telescopic plate 202; without using the extrusion block 5 in Embodiment 1, the driving end of the first driving member 102 is fixedly connected to the electric telescopic plate 202, and the front and rear sides of the electric telescopic plate 202 are respectively fixedly connected to the adjacent protective block 201; during the label tearing process, the electric telescopic plate 202 expands to the front and rear sides to stretch the label, which helps to smooth out the longitudinal wrinkles on the label and improve the labeling yield.

[0046] It also includes an electric heating element 203; the electric heating element 203 is installed on the right side of the clamp 4; during the label re-tearing process, the label is preheated by the electric heating element 203 to melt the glue under the label, which is conducive to the label re-tearing. At the same time, the preheating of the label by the electric heating element 203 prevents the label from delaminating during the re-tearing process, thus protecting the label.

[0047] Example 3

[0048] Based on Example 2, such as Figure 1 , Figure 2 and Figure 12 As shown, it also includes a glue applicator 301; the glue applicator 301 is installed on the first mounting bracket 2; during the label re-application process, glue is sprayed onto the lithium battery through the glue applicator 301 to prevent the label from being not sticky enough during the label re-application process and failing to perfectly adhere to the lithium battery, thus ensuring the labeling yield.

[0049] The glue applicator 301 is equipped with three glue spray nozzles 30101, which are inclined to the lower right. The glue is evenly sprayed onto the lithium battery through the several glue spray nozzles 30101 that are inclined to the lower right, so as to achieve uniform glue spraying. When the lithium battery is transferred to the underside of the electric telescopic plate 202, the electric telescopic plate 202 presses the label, so that the glue is evenly distributed under the label, which is conducive to the adhesion of the label and ensures the yield of the labeling product.

[0050] The protective block 201 is provided with a cleaning surface 20102; when the lithium battery is transferred to the electric telescopic plate 202, the overflowing glue is scraped off by the cleaning surface 20102 to prevent the overflowing glue from flowing into the lithium battery and contaminating the components, thus ensuring the yield of lithium battery products.

These descriptions are merely for explaining the principles of the embodiments of the present invention and should not be construed as limiting the scope of protection of the embodiments of the present invention in any way. Based on the explanation herein, those skilled in the art can conceive of other specific embodiments of the present invention without creative effort, and these embodiments will all fall within the scope of protection of the embodiments of the present invention.
