Description

Technical Field

[0001] The utility model relates to the technical field of batteries, in particular to a lug gluing device. Background Art

[0002] The strip tabs usually need to be coated with glue during the preparation process. The main purpose of the coating is to provide good contact and bonding properties to ensure the reliability and stability of the connection between the metal conductor and other components such as battery cells, insulating materials, etc.

[0003] Specifically, the important roles of glue coating include:

[0004] Conductive properties: Applying a suitable conductive adhesive can improve current conduction efficiency and reduce contact resistance, thereby improving the working efficiency and performance of the battery.

[0005] Mechanical support: Gluing can enhance the mechanical support and fixation between metal conductors and other components, reducing the risk of breakage or damage caused by vibration or physical force loading.

[0006] Durability and stability: Correct selection and use of appropriate coating materials can improve the durability and stability of the tabs, extend the battery life and reduce the possibility of failure.

[0007] Battery safety: In high energy density batteries such as lithium-ion polymer batteries, glue coating can provide additional safety protection to avoid short circuits in internal battery components or reduce the risk of their occurrence.

[0008] During the gluing process of the strip tabs, the glue may run out, but the conveying device through which the strip tabs pass is still operating, resulting in some sections of the tabs not being glued and going directly to the next process, affecting the use of the tabs. For this reason, we propose a tab gluing equipment to solve the existing problem. Utility Model Content

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1-Figure 4 As shown, the utility model proposes a lug gluing device, comprising a detection box 2, an infrared sensor device 3, a base plate 5, a mounting column 8 and a screw 17, the detection box 2, a gluing device 6 and a reeling device 7 are respectively arranged above the base plate 5, support rollers 1 are arranged at both ends of the detection box 2, and the support rollers 1 are connected to the detection box 2 through a rotating bracket 19, pillars 4 are arranged at the four corners of the lower end of the detection box 2, and the lower ends of the pillars 4 are connected to the base plate 5, the lower end of the detection box 2 is provided with an infrared sensor device 3, the upper and lower ends of the detection box 2 are respectively provided with a transmitter 12 and a receiver 11, the inner ends of both ends of the detection box 2 are provided with mounting columns 8, the lower ends of the mounting columns 8 are provided with sliders 10, the inner wall of the lower end of the detection box 2 is provided with symmetrically distributed guide rails 23, the sliders 10 are slidably installed inside the guide rails 23, the upper end of the detection box 2 is provided with a travel groove 18, a mounting block 21 is installed at the upper end, and the mounting block 21 is slidably installed inside the travel groove 18.

[0027] Based on the implementation steps of Example 1: the unwinding device 7 conveys the strip-shaped pole ear, and when passing through the glue coating device 6, the pole ear is coated with glue, the strip-shaped pole ear passes through the detection box 2, and the two ends are supported by the guide wheel 9, and the limit ring 15 limits the strip-shaped pole ear. The strip-shaped pole ear is guided and transported inside the detection box 2, and the transmitter 12 generates an infrared beam and irradiates it to the surface of the strip-shaped pole ear. The transmitter 12 usually uses an infrared LED, and the receiver 11 is used to receive and detect the infrared light signal reflected back by the pole ear, and convert the light signal into an electrical signal. The infrared sensor device 3 receives the signal, and through the internal signal processing and discrimination circuit, it is responsible for amplifying, filtering and further processing the received electrical signal to extract an effective infrared radiation change signal. Then, according to the set threshold condition, the signal is discriminated to determine whether the glue coating is broken. The infrared sensor device 3 continuously monitors the infrared light signal reflected by the surface of the pole ear. If the glue coating is broken, it will cause the infrared radiation change on the surface of the pole ear, which is captured by the receiver 11 and analyzed by the signal processing and discrimination circuit. Once a glue breaking event is detected, the system controls the alarm 13 to sound an alarm or trigger a corresponding control operation.

[0029] In this embodiment, the torsion block 16 is rotated to rotate the screw 17, and the screw 17 pushes the threaded block 22 to move relative to or away from each other through the threads relatively distributed on the outer wall, so that the mounting column 8 moves synchronously inside the detection box 2. The width specifications of the strip pole ears are different according to the type of battery used. The mounting column 8 can achieve effective guided transportation of strip pole ears of different specifications by moving the position of the adjusting guide wheel 9.
