Description

Technical Field

[0001] This application relates to the technical field of tension detection, and particularly relates to a tension detection tool. Background Art

[0002] In battery manufacturing, especially in processes such as coating, die-cutting, and winding and unwinding, roller components such as guide rollers and pressure rollers are usually used in the above operations. The tension on the electrode sheet and diaphragm is applied by the roller components. Whether the magnitude of the tension meets the production requirements directly determines the quality of the product. Therefore, before each production, it is necessary to detect the tension applied to the electrode sheet and diaphragm to confirm whether the tension meets the requirements. Currently, the equipment tension detection tool is a weight and a connecting wire. The wire is used to suspend the weight, and the wire is connected according to the tape running mode. The tension display value on the equipment control panel is compared with the weight mass value to obtain a conclusion on whether the tension meets the regulations. However, there are the following problems in the detection operation:

[0003] 1. When detecting tension, it is necessary to use a weight with a mass corresponding to 50% of the maximum range of the tension sensor on the tension control equipment for detection. The weight mass is generally 25KG to 50KG. With a large weight mass, it is difficult to perform the tension detection operation.

[0004] 2. Due to the large weight mass, the designed position of the guide roller is either too high or too low. During the tension detection process, with the weight hanging high, there are great potential safety hazards.

[0005] 3. According to ergonomic calculations, the safety standard is 10KG. In the operation of detecting tension, the weight mass far exceeds the safety standard, presenting great potential safety hazards.

[0006] In view of this, it is necessary to provide a tension detection tool to solve the above problems. Summary of the Invention

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts fall within the scope of protection of the present application.

[0029] In response to the deficiencies or one of the deficiencies proposed in the above background technology, the embodiments of the present application provide a tension detection tool, which can remove large-mass weights during tension detection, achieving the purpose of optimizing the operation mode and improving operation safety.

[0030] See Figure 1 and Figure 2 As shown, the embodiments of the present application provide a tension detection tool, including:

[0031] A housing 1, with a cavity provided inside;

[0032] A wire winding and unwinding mechanism, which includes a winding wheel 2 arranged in the cavity of the housing 1 and a connecting line 3 connected to the winding wheel 2 and having one end passing through the housing 1. The winding wheel 2 is used to wind the connecting line 3 to tension the connecting line 3 on the device to be measured;

[0033] A connector 4, which is connected to the housing 1 through a sensor 5, and the sensor 5 is used to detect the tension of the connecting line 3.

[0034] In the housing 1 of the tension detection tool according to the embodiment of the present application, a wire winding and unwinding mechanism is provided, which can adjust the length of the connecting wire 3 extending out of the housing 1 through the wire winding wheel 2. During tension testing, the connecting wire 3 is arranged on the device to be detected according to the tape running mode, and the end of the connecting wire 3 and the connecting member 4 are respectively fixed at both ends of the device to be detected.

[0035] The connecting wire 3 is tightened by rotating the wire winding wheel 2 to provide tension. The connecting member 4 and the sensor 5 cooperate to detect the tension of the connecting wire 3. A set tension value is applied to the device to be detected through the connecting wire 3, and the tension value is compared with the tension value displayed on the control panel of the device to be detected, so as to check whether the tension of the device to be detected meets the requirements.

[0036] It should be noted that the device to be detected is a tension control device. A tension sensor cooperating with a tension roller is provided on the tension control device. Together with the control unit of the tension control device itself, the tension of the connecting wire 3 passing around the tension roller can be measured and compared with the tension value controlled by the tension detection tool of the present application, so as to realize the tension detection and verification.

[0037] Exemplarily, in this embodiment, the connecting member 4 can be a hook or a rope, and the sensor 5 can be a tension sensor or a tensile force sensor. The wire winding wheel 2 is rotatably connected to the housing 1. One end of the sensor 5 is fixedly installed on the housing 1, and the other end is fixedly installed with the connecting member 4.

[0038] The wire winding wheel 2 can be driven manually or electrically. Exemplarily, when the wire winding wheel 2 is controlled to rotate manually, a bolt can be used instead of a rotating shaft to realize the rotational connection between the wire winding wheel 2 and the housing 1. When it is necessary to lock the position of the wire winding wheel 2, the bolt passing through the wire winding wheel 2 and the housing 1 can be tightened to lock the wire winding wheel 2;

[0039] In some other embodiments, the position of the wire winding wheel 2 can also be locked by the cooperation of a ratchet and a pawl. The ratchet and the wire winding wheel 2 are rotatably connected to the housing 1 through the same rotating shaft. The housing 1 is equipped with a pawl cooperating with the ratchet, and the ratchet is limited by the pawl, thereby preventing the wire winding wheel 2 from rotating in reverse and causing the connecting wire 3 to become loose.

[0040] When the wire winding wheel 2 is driven electrically, a stepping motor with self-locking ability can be used to drive the wire winding wheel 2 to rotate. Specifically, the wire winding wheel 2 is rotatably connected to the housing 1 through a rotating shaft, and the output end of the stepping motor is fixedly connected to the rotating shaft.

[0041] During testing, the connecting member 4 and the end of the connecting wire 3 are fixed at both ends of the device to be detected. The wire winding wheel 2 is rotated to tighten the connecting wire 3. The connecting wire 3 pulls the housing 1 through the wire winding wheel 2, and the housing 1 pulls the connecting member 4 through the sensor 5, so that the sensor 5 can detect the tension of the connecting wire 3.

[0042] That is, the tension detection tool of the present application is combined with a wire winding wheel 2 and a sensor 5, having a tension providing function with adjustable tension. By replacing large-mass weights with a small-mass tension detection tool, the operation mode is optimized and the operation safety is improved.

[0043] Meanwhile, by realizing adjustable tension, different weights required for different tension detections are removed, the tool ratio is reduced, and the tension detection cost is lowered. In addition, by removing large-mass weights, the operation convenience is improved, the time consumed for tension detection is reduced, and the production efficiency of the equipment is increased.
