Description

Technical Field

[0001] This utility model belongs to the field of battery production technology, specifically relating to an automatic label-setting and paper-attaching device. Background Technology

[0002] In the production process of some battery cells, labels need to be affixed to the head of the cell to facilitate subsequent identification and traceability. The label typically consists of a main body and an extension. The main body is attached to the top surface of the cell head, and the extension is attached to one side of the cell head. During labeling, the extension is usually attached to one side of the cell head first for initial positioning, before the main body is affixed. Before attaching the main body, an adhesive paper is usually affixed to its surface; therefore, this paper must be removed before attaching the main body.

[0003] Existing paper-tearing equipment typically holds the label horizontally during the paper-tearing process. The grippers pick up the tear tabs on the paper and tear it off under the drive of a rotary cylinder. Since the main body of the label is suspended in the air before being attached, its relative position to the battery cell is not fixed. This causes instability in the paper-tearing process, affecting efficiency. Furthermore, the label is prone to being torn during the tearing process, impacting the quality of the tearing operation. Utility Model Content

[0004] To address the shortcomings of the existing technology, this utility model provides an automatic label-erecting and paper-attaching device. The device guides the label and the attached paper to be in an upright position through a guide label-erecting part, and adsorbs and fixes the label through a label-adsorption part. This allows the label to remain fixed during the paper-attaching process, thereby improving the stability and efficiency of the process.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.

[0036] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0037] Example 1

[0038] refer to Figures 1 to 4The automatic label-erecting and paper-attaching device provided in this embodiment includes a conveying mechanism 1, and a label-erecting and suction mechanism 2 and a paper-attaching mechanism 3 respectively disposed on opposite sides of the conveying mechanism 1. The label-erecting and suction mechanism 2 includes a label-erecting suction component 21 and a first driving assembly 22 for driving the label-erecting suction component 21 to move horizontally. The first driving assembly 22 can be a drive motor or a drive cylinder. The label-erecting suction component 21 is provided with a guide label-erecting part 211 and a suction part 212 sequentially along the conveying direction of the conveying mechanism 1. The paper-attaching mechanism 3 includes a clamping assembly 31 and a second driving assembly 32 for driving the clamping assembly 31 to move closer to or away from the conveying mechanism 1. The second driving assembly 32 can be a robotic arm.

[0039] It should be noted that in this embodiment, the battery cell fed onto the conveying mechanism 1 is in an upright state. The label and attached paper at the head of the battery cell may be in a partially upright state or tilted towards the side closer to the label-holding and label-absorbing mechanism 2. Before the battery cell is conveyed to the position of the label-holding and label-absorbing mechanism 2, the label-holding and label-absorbing component 21 will first move under the drive of the first driving component 22 to a position above the conveying mechanism 1 and on one side of the battery cell's moving direction. When the battery cell reaches the position of the label-holding and label-absorbing mechanism 2, the label and attached paper will... First, the label contacts the guide label-erecting part 211 and tends to stand upright under its guidance. When the label and attached paper move to the position of the label-absorbing part 212, the conveying mechanism 1 stops conveying. The label-absorbing part 21, driven by the first driving component 22, moves further towards the label, pushing the label and attached paper to make them stand upright and adsorbing and fixing the label. Then, the clamping component 31 clamps the tear tab of the attached paper, and the attached paper is torn off the label horizontally under the drive of the second driving component 32. Through the cooperation of the guide label-erecting part 211 and the label-absorbing part 212, the label can maintain a stable upright state during the label-tearing operation, improving the stability and efficiency of the label-tearing operation. At the same time, it can also prevent the label from being torn during the label-tearing operation, which is conducive to improving the quality of the label-tearing operation.

[0040] In one embodiment, the guide sign section 211 includes a first guide slope 2111 and a second guide slope 2112. The first guide slope 2111 is connected to one side of the second guide slope 2112. The first guide slope 2111 is formed by the width of the guide sign section 211 gradually increasing from narrow to wide along the conveying direction of the conveying mechanism 1, and the second guide slope 2112 is formed by the thickness of the guide sign section 211 gradually increasing along the conveying direction of the conveying mechanism 1. Through the cooperation of the first guide slope 2111 and the second guide slope 2112, the guiding requirements of labels and attached paper in different states can be met. For example, the first guide slope 2111 can meet the guiding requirements of labels and attached paper in a partially upright state, while the dual guiding effect of the first guide slope 2111 and the second guide slope 2112 can meet the guiding requirements of labels and attached paper in a tilted state.

[0041] In one embodiment, the label suction part 212 includes a plurality of suction holes 2121 provided on the side wall of the label suction part 212 near the paper tearing mechanism 3. Through the adsorption effect of the suction holes 2121, the label can be tightly attached to the side wall of the label suction part 212, so that the label is in a completely upright state.

[0042] In some embodiments, a clearance groove 213 is provided between the guide label-standing part 211 and the label-absorbing part 212. The clearance groove 213 is located on the working path of the clamping component 31. The clearance groove 213 can allow the label-standing and label-absorbing part 21 to avoid the clamping action and paper-tearing action of the clamping component 31, so as to avoid interfering with the operation of the clamping component 31 and ensure the normal operation of the paper-tearing device.

[0043] Example 2

[0044] As a further optimization of Example 1, refer to Figures 5 to 6 The clamping assembly 31 includes a first gripper 311, a second gripper 312, and an opening and closing drive member 313. The first gripper 311 and the second gripper 312 are both driven to connect with the opening and closing drive member 313. The opening and closing drive member 313 can drive the first gripper 311 and the second gripper 312 to open or close. The opening and closing drive member 313 can be a drive cylinder.

[0045] As a further optimization, a first guide tilting portion 3111 is formed at the end of the first gripper 311 near the side of the second gripper 312, and a second guide tilting portion 3121 is formed at the end of the second gripper 312 for cooperating with the first guide tilting portion 3111. The tilting direction of the first guide tilting portion 3111 is in line with the tearing direction of the attached paper. It can be understood that when one end of the attached paper is torn off, a certain angle will be formed between the attached paper and the label. The tilting direction of the first guide tilting portion 3111 is adapted to the tearing direction of the attached paper, and the tilting angle is adapted to the angle formed between the attached paper and the label. When the clamping component 31 clamps the tearing lug of the attached paper, it will cause the end of the attached paper near the tearing lug to tilt away from the label, forming a pre-separation tendency. This is conducive to the rapid separation of the attached paper and the label, further improving the efficiency of the attached paper tearing operation, and preventing the label from being torn during the attached paper tearing operation, further improving the quality of the attached paper tearing operation.

[0046] As a further optimization, a first protruding tooth 3112 is formed on the side wall of the first guide inclined portion 3111 near the second gripper 312, and a second protruding tooth 3122 is formed on the second guide inclined portion 3121 for meshing with the first protruding tooth 3112. Through the mutual cooperation of the first protruding tooth 3112 and the second protruding tooth 3122, the clamping force of the first gripper 311 and the second gripper 312 on the attached paper can be improved, further enhancing the stability and efficiency of the paper tearing operation.

[0047] Example 3

[0048] As a further optimization of Example 2, refer to Figures 7 to 10 The automatic label-setting and label-tearing device also includes a label-recycling mechanism 4 located on one side of the label-tearing mechanism 3. The label-recycling mechanism 4 includes a label-recycling bin 41 and a vacuum suction component 42 located at the bottom of the label-recycling bin 41. The label-recycling bin 41 is located on the working path of the clamping component 31. After the clamping component 31 completely tears the label off, the label can be transferred into the label-recycling bin 41. Due to the suction effect of the vacuum suction component 42, when the clamping component 31 releases the label, the label will quickly fall into the bottom of the label-recycling bin 41 under the suction force, effectively preventing the label from sticking to the clamping component 31 and improving the efficiency of the label-tearing operation.

[0049] As a further optimization, the top of the paper storage compartment 41 is provided with an opening 411, and antistatic brushes 412 are evenly distributed on both sides of the opening 411, covering the opening 411. It is understood that the antistatic brushes 412 arranged on both sides of the opening 411 are facing each other and the spacing is small and negligible, thus allowing the antistatic brushes 412 to completely cover the opening 411. Since there are gaps between adjacent bristles in the antistatic brushes 412 and the bristles can deform and bend under external force, the first gripper 311, the second gripper 312, and the attached paper are allowed to pass through the antistatic brushes 412. When the first gripper 311, the second gripper 312, and the attached paper pass through the antistatic brushes 412, they will all rub against the antistatic brushes 412 sufficiently, thereby eliminating static electricity between the attached paper and the first gripper 311 and the second gripper 312, further preventing the attached paper from sticking to the first gripper 311 and the second gripper 312.

[0050] In some embodiments, the conveying mechanism 1 includes a horizontal linear guide rail 11, a plurality of conveying trolleys 12 slidably connected to the horizontal linear guide rail 11, and a third drive assembly 13 for driving the conveying trolleys 12 to move along the horizontal linear guide rail 11. The third drive assembly 13 can be a drive motor. A limit plate 14 is erected on the conveying trolley 12, and a push clamp assembly 15 is provided on one side of the limit plate 14. Through the cooperation of the limit plate 14 and the push clamp assembly 15, the battery cell can be erected and fixed on the conveying trolley.

[0051] In some implementations, the number of conveying trolley 12, label-holding component 21, clamping assembly 31, and paper-attachment recycling mechanism 4 are all two. Thus, in each work cycle, two battery cells can be simultaneously stripped of paper, which helps to improve battery cell production efficiency.
