Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of lead-acid battery production detection device equipment, and specifically relates to a battery separator bag detection tooling. Background Art
[0002] When manufacturing a starter battery, the negative plate needs to be inserted into a PE separator bag, and then assembled with the positive plate into a battery cell. However, there are major quality risks in the process of loading the negative plate into the bagged PE separator. For example, the sharp edges of the negative plate can easily puncture the separator, resulting in a short circuit inside the battery. The utility model with publication number CN202205858U discloses a battery cell, in which the two sides of the positive plate are arranged in a circular tube shape, and the side without edges can avoid puncturing the bagged PE separator when bagging, thereby avoiding a short circuit inside the battery. For another example, the utility model with publication number CN202210546U discloses a bagged PE separator, including a front separator, a rear separator, and a suture provided at the junction of the front separator and the rear separator. The suture is U-shaped; this structure can effectively prevent this process from exerting destructive force on the suture.
[0003] However, in the actual production process, the installation state of the negative plate is also strongly related to the internal dimensions of the PE separator bag. A high height of the separator bag will affect the quality of cast welding, and a low height of the separator bag will cause a short circuit between the positive and negative electrodes of the plate. A small internal dimension of the separator bag will cause the plate to leak, affecting the battery capacity. A large internal dimension of the separator bag will cause the plate to move after cast welding, thus affecting the welding quality. Therefore, it is necessary to control the internal dimensions of the PE separator bag.
[0004] The traditional testing method is to dismantle and destroy the PE separator bag and compare the measurement results with the standard size with a vernier caliper to determine whether the internal dimensions are qualified. The traditional testing method is difficult and the measurement is inaccurate, which ultimately affects the judgment results. Utility Model Content
[0005] The utility model provides a battery separator bag detection tool, which can quickly detect whether the internal dimensions of a PE separator meet process requirements and can ensure the accuracy of the test result.

[0011] The surface of the mainboard is provided with a detection groove extending in the width direction, the upper side wall of the detection groove is the upper limit detection line, and the lower side wall of the detection groove is the lower limit detection line.
[0012] By arranging a detection groove extending along the width direction on the surface of the mainboard, it is convenient for operators to perform detection from different angles.
[0013] The blade is arranged on one side surface of the mainboard, one end of the blade is provided with a mounting hole, and the blade is rotatably connected to the mainboard via a rivet passing through the mounting hole, so as to facilitate the rotation of the blade during detection.

When one end of the screw head is pressed into the countersunk hole, the blade can be switched between the retracted state and the detection state.
[0015] By setting the countersunk hole and the screw, the screw can be easily installed on the main board, and can be easily adjusted and operated. Since the screw can be extended and retracted in the thickness direction of the main board, the position of the blade can be adjusted and changed more easily. Through the cooperation of the screw and the limit nut, a stable support and fixing effect can be provided. At the same time, by setting a screw corresponding to each blade, and one end of the screw passes through the main board, cooperates with the limit nut, as well as the countersunk hole, the screw and the reset spring, it can be ensured that the blade switches between the retracted state and the detection state more smoothly and stably.

[0025] Furthermore, upper limit detection lines and lower limit detection lines are provided on both sides of the mainboard 1. Such a setting can improve the precision and accuracy of detection, and setting detection lines on both sides can facilitate operators to perform detection from different angles and improve work efficiency.
[0026] The surface of the mainboard 1 may also be provided with a detection groove extending in the width direction, the upper side wall of the detection groove is the upper limit detection line 2, and the lower side wall of the detection groove is the lower limit detection line 3. This can facilitate the operator to perform detection.
[0027] The blade 4 is arranged on one side surface of the main board 1, and a mounting hole is arranged at one end of the blade 4.
