Description

Technical Field

[0001] The present application relates to the technical field of power battery production, and specifically discloses an automatic labeling device for power battery production. Background Art

[0002] With the leapfrog development of new energy vehicles, power battery technology is constantly being updated, so the demand for power battery production automation has also increased. Before the power batteries of new energy vehicles are produced and shipped, they need to be labeled on the surface of the battery. The label with information such as the battery name, model, specification, production batch and factory date is affixed to a uniformly designated position on the surface of the battery. In order to ensure the service life of the label, acrylic sheet is usually used as the label material, and the battery information is printed on the label surface.

[0003] In existing power battery production lines, workers usually manually affix labels, which mainly includes the steps of taking the label, tearing off the label adhesive, and affixing the label. However, manual labeling is inefficient and it is easy to affix the label in the wrong position or in the opposite direction, so that the factory quality of the power battery cannot be guaranteed. Therefore, in view of this, the inventor provides an automatic labeling device for power battery production to solve the above problems. Utility Model Content

[0005] In order to achieve the above-mentioned purpose, the basic scheme of the utility model provides an automatic labeling device for power battery production, including a base plate, a frame mounted on the base plate, a workbench arranged on the frame, and a controller arranged on the base plate and located on one side of the frame, the workbench is provided with a stacking frame for vertically stacking labels, the frame is provided with a back glue peeling mechanism for peeling off the back glue of the labels located on one side of the stacking frame, the frame is also provided with a storage box adjacent to the workbench for storing the torn off label back glue waste, the workbench is provided with a discharge trough located at the bottom of the stacking frame and connected to the bottom of the stacking frame, and the workbench is also provided with a device for pushing the labels at the bottom of the stacking frame to A material pushing mechanism is provided out of the stacking frame, and a material grabbing mechanism is provided on the frame for grabbing and changing the spatial position of the label. The frame is also provided with a labeling table for placing power batteries. The material grabbing mechanism includes a fixed seat arranged at the end of the frame away from the controller, a three-axis linear module arranged on the top of the fixed seat, an electric material grabbing claw connected to the end of the three-axis linear module, and a color mark sensor for identifying the surface of the label installed at the end of the three-axis linear module and located on one side of the electric material grabbing claw. A rotating drive component is provided at the end of the three-axis linear module for driving the electric material grabbing claw to rotate, and the three-axis linear module, the electric material grabbing claw and the color mark sensor are all electrically connected to the controller.

[0006] The principles and effects of this basic solution are:

It is convenient for tearing and storing the adhesive on the label before labeling by arranging a back adhesive peeling mechanism and a storage box. It is convenient for workers to load and unload power batteries by arranging a labeling table. By using the labeling table, it is convenient for workers to place the power battery to be labeled on the labeling table. It is convenient for the grasping mechanism to stick the label with the back adhesive peeled off on the designated position of the power battery, and then the worker can remove the labeled power battery and replace the power battery to be labeled. By using a controller to control the overall structure, the automatic control of the entire power battery labeling operation process is realized, making the production process of the power battery more coherent.

At the same time, by installing a color mark sensor on the three-axis linear module, the function of identifying the surface of the label is realized, so as to quickly identify whether the placement direction and position of the label are correct. By setting a rotating drive member to control the rotation movement of the electric material grabbing claw, it is convenient to adjust the orientation and position. The upside-down labels are corrected to avoid the situation where the labels are pasted upside down. The entire labeling production process, from material collection and discharge, label peeling, label adhesive recovery to labeling on the power battery, is carried out automatically and continuously, which improves the production efficiency of the power battery. At the same time, the process quality of power battery labeling is controlled to avoid the situation where the labels are pasted incorrectly or upside down, which greatly improves the production and factory quality of the power battery and solves the problem that the traditional power battery labeling is done manually by workers during production, which makes it easy to paste the label in the wrong position or in the opposite direction, making the factory quality of the power battery not guaranteed.

[0011] Furthermore, the pushing mechanism includes an electric telescopic pushing rod detachably mounted on an end of the workbench away from the fixed seat and arranged parallel to the stacking frame, a connecting plate arranged at the end of the electric telescopic pushing rod, a pushing trough arranged on the workbench and between the stacking frame and the electric telescopic pushing rod, and a pushing plate arranged at the bottom of the connecting plate and able to slide in the pushing trough, the electric telescopic pushing rod is electrically connected to the controller, the pushing trough is connected to the discharging trough, the depth of the discharging trough, the depth of the pushing trough, the thickness of the label and the thickness of the pushing plate are all equal, the width of the discharging trough is equal to the width of the label, the width of the pushing trough is equal to the width of the pushing plate, the stacking frame is located between the discharging trough and the pushing trough, and a limit block is provided at the end of the discharging trough away from the stacking frame. By setting a pushing trough, an electric telescopic pushing rod and a pushing plate, and setting the relationship between the outer dimensions of the discharge trough, the pushing trough, the label and the pushing plate, the pushing plate can be used to push the label at the bottom of the stacking frame from the bottom of the stacking frame and into the discharge trough, which not only realizes the discharge of the label, but also makes it easier for the electric grabbing claw to grab and move the label pushed into the discharge trough.

[0012] Furthermore, the ratio of the width of the discharge slot to the pushing slot is not less than 1. By limiting the ratio of the width of the discharge slot to the pushing slot to not less than 1, the pushing plate can more conveniently push the label from the stacking frame to the discharge slot.

[0030] In the specific implementation process of the utility model, material preparation is required before production operation. Workers stack a batch of labels 5 with the adhesive backing not removed in an upright position with the adhesive backing facing downward in a stacking frame 6, and take a power battery that needs to be labeled 5 and place it on the labeling table 9, and then start labeling 5.

[0031] First, the labels 5 need to be unloaded from the stacking frame 6 and transferred to the loading rack 28. The controller 4 controls the electric telescopic push rod 21 to extend, thereby driving the push plate 24 to slide in the direction of the stacking frame 6 in the push slot 23 through the connecting plate 22. When entering the stacking frame 6, the push plate 24 pushes out a piece of label 5 at the bottom of the stacking frame 6 and pushes it into the discharge slot 8. At this time, the push plate 24 provides support for the labels 5 inside the stacking frame 6, and the remaining labels 5 inside the stacking frame 6 remain stationary. After the end of the label 5 away from the electric telescopic push rod 21 abuts against the limit block 25, the electric telescopic push rod 21 stops extending and is controlled by the controller 4 to retract. When the electric telescopic push rod 21 retracts and exits the bottom of the stacking frame 6, the label 5 in the stacking frame 6 moves down one layer along the stacking frame 6 and falls on the surface of the discharge slot 8, completing the unloading of one label 5.

[0032] Then, the label 5 at the end of the discharge trough 8 is transferred to the adhesive peeling mechanism for the process of peeling the adhesive back of the label 5. The controller 4 controls the three-axis linear module to slide and drive the electric gripping clamp 11 and the color mark sensor 12 to adjust the position, and moves the color mark sensor 12 to the top of the label 5, and detects the upper surface of the label 5 below the color mark sensor 12.

[0033] After the color mark sensor 12 detects the label 5, when the color mark sensor 12 detects and identifies that the upper surface of the label 5 is a color coating, it indicates that the label 5 is placed in the correct direction, and then the label 5 is transferred, the adhesive backing is removed, and the label 5 is attached. The specific operations are: first, the controller 4 controls the three-axis linear module to slide and drive the electric material grabbing claw 11 and the color mark sensor 12 to adjust the position. At this time, the electric material grabbing claw 11 is in an open state, and the controller 4 controls the horizontal drive member 16 to drive the vertical guide rail 14 to move horizontally, so that the electric material grabbing claw 11 moves toward the front side of the workbench 3 to the top of the label 5 to be attached in the discharge trough 8, and then the vertical drive member 17 drives the longitudinal axis slide 15 to move downward The electric material grabbing claws 11 are located on both sides of the label 5 to be pasted, and then the controller 4 controls the electric material grabbing claws 11 to close so as to clamp and fix the label 5. Then the controller 4 controls the three-axis linear module to slide again and drives the electric material grabbing claws 11 and the color mark sensor 12 to adjust the position, and moves the electric material grabbing claws 11 to the top of the material rack 28 and then places the label 5 on the material rack 28. At this time, the electric material grabbing claws 11 keep clamping and fixing the label 5, and then the controller 4 controls the longitudinal drive 18 and the feeding drive 33 to be powered on and started, driving the fixed plate 19 and the material loading slide 26 to slide synchronously in the direction of the storage box 7 until the end of the label 5 on the material rack 28 is located above the box opening of the storage box 7, and then Then, the controller 4 controls the tearing drive member 31 to drive the tearing slide 29 to slide in the direction of the material rack 28, so that the end of the embedded glue plate 30 is embedded between the label 5 and the adhesive backing, and the adhesive backing is pressed between the embedded glue plate 30 and the material rack 28. Then, the controller 4 controls the vertical drive member 17 to drive the longitudinal axis slide 15 to slide upward, thereby driving the electric material grabbing claw 11 and the label 5 clamped and fixed by it to separate from the material rack 28 and rise. The controller 4 then controls the horizontal drive member 16, the vertical drive member 17 and the longitudinal drive member 18 to coordinate and control the vertical guide rail 14, the longitudinal axis slide 15 and the fixed plate 19 to move, thereby driving the electric material grabbing claw 11 and the label 5 with the adhesive backing torn off to move and place them on the power battery on the labeling table 9. At the same time, the controller 4 controls the tearing drive 31 to drive the tearing slide 29 to slide toward the material rack 28 again, so that the embedded glue plate 30 pushes the adhesive on the material rack 28 forward to the storage box 7 for recovery. Finally, the controller 4 controls the electric material grabbing claw 11 to open and move to the upper end of the discharge chute 8 to transfer, tear off the adhesive and stick the next label 5. After the power battery is labeled 5, the worker removes the power battery with the label 5 on the labeling table 9, and puts a new power battery that needs to be labeled 5 on the labeling table 9, thereby performing the next labeling 5 work cycle.

[0034] After the color mark sensor 12 detects the label 5, when the color mark sensor 12 does not detect and identify that the upper surface of the label 5 is a color coating, it indicates that the label 5 is placed in the opposite direction. At this time, the electric material grabbing clamp 11 must be controlled to close to clamp the label 5, and then the controller 4 controls the rotating drive to drive the fixed plate 19 to rotate 180 degrees, so that the electric material grabbing clamp 11 and the label 5 are both facing upward, and then the controller 4 controls the three-axis linear module to drive the electric material grabbing clamp 11 and the label 5 with the corrected direction to move to the top of the discharge trough 8, and controls the electric material grabbing clamp 11 to open and place the label 5 on the discharge trough 8, and then similarly perform the above-mentioned operation procedures of transferring the label 5, tearing off the adhesive backing and pasting the label 5 to complete the labeling 5 processing of the power battery.

[0035] Compared with the prior art, the utility model realizes the function of grabbing and moving the label 5 by setting a material grabbing mechanism to replace the traditional manual operation of workers, uses the electric material grabbing claw 11 to grab the label 5 in the stacking frame 6, and uses the controller 4 to electrically control the three-axis linear module and the electric material grabbing claw 11 to change the displacement in space, thereby realizing the position change of the label 5. At the same time, by installing a color mark sensor 12 on the three-axis linear module, the function of identifying the surface of the label 5 is realized, so as to quickly identify whether the placement direction and position of the label 5 are correct. By setting a rotating drive member to control the rotation movement of the electric material grabbing claw 11, it is convenient to adjust the orientation. The label 5 that is in the wrong position is corrected to avoid the label 5 being pasted upside down. The entire labeling production process from material taking and discharging, tearing off the adhesive back of the label 5, recycling the adhesive back of the label 5 and pasting the label 5 on the power battery is automatically and continuously carried out, which improves the production efficiency of the power battery. At the same time, the process quality of power battery labeling 5 is controlled to avoid the label 5 being pasted incorrectly or upside down, which greatly improves the production and factory quality of the power battery and solves the problem that the traditional power battery labeling is done manually by workers during production, which is easy to paste the label in the wrong position or in the opposite direction, making the factory quality of the power battery cannot be guaranteed.
