Description

Technical Field

[0001] The utility model relates to the technical field of terminal detection, in particular to a lead terminal detection tool for a lead-acid battery. Background Art

[0002] The size and taper of the positive and negative terminals of the battery must meet the national standard requirements to ensure that the wiring clips are in close contact with the battery terminals; otherwise, poor wiring contact and loose connections will occur, leading to poor starting, and in severe cases, sparks and open flames. Currently, the battery manufacturing industry measures the taper of the battery terminals when testing the batteries off the line.

[0003] At present, when inspecting the lead-acid battery terminals, the inspection tool used is a gasket tooling inspection. The original inspection tooling is a manual inspection with slow inspection efficiency and non-standard inspection standards. Therefore, a lead-acid battery lead terminal inspection tooling is proposed to solve this problem. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model provides a lead-acid battery lead terminal inspection tooling, and the specific technical solution is as follows:

[0006] Fixed frame;

[0007] A cylinder is arranged on the top of the fixing frame,

[0008] The detection assembly includes a movable plate fixedly arranged at the output end of the cylinder and a check fixture arranged on the fixed movable plate, wherein the check fixture includes a sleeve and a positioning column movably plugged into the top of the sleeve, and a conical hole for detecting the taper of the battery terminal is arranged inside the sleeve and below the positioning column, wherein the conical hole gradually decreases from bottom to top, and the taper is consistent with the taper of the upper part of the battery terminal;

[0009] The optical fiber sensor is arranged on the top of the fixing frame, the probe of the optical fiber sensor is fixed on the top of the inspection tool, and the cylinder drives the moving plate to drive the inspection tool to descend to detect the battery terminals.

[0010] As an improvement of the above technical solution, two groups of guide rods are arranged in the fixed frame, and the two ends of the movable plate are slidably connected to the guide rods.

[0011] As an improvement of the above technical solution, a placement groove for the limit terminal is provided at the bottom of the fixing frame and below the inspection fixture.

[0012] As an improvement of the above technical solution, a limiting groove is provided on the surface of the positioning column. When the limiting groove is not exposed or completely exposed from the sleeve, it indicates that the battery terminal is unqualified.

[0013] As an improvement of the above technical solution, two groups of movable columns are symmetrically arranged on the surface of the positioning column and below the limiting groove, and a sliding groove for the movable column to move up and down is opened on the surface of the sleeve.

[0014] As an improvement of the above technical solution, a fixing seat is fixedly sleeved on the outer surface of the sleeve, and the fixing seat is fixedly connected to the movable plate by bolts.

[0015] As an improvement of the above technical solution, a mounting track is provided on the top of the fixing frame, and the mounting track is detachably connected to the optical fiber sensor.

[0016] Beneficial effects of the utility model:

[0017] The cylinder drives the moving plate to move the inspection fixture down, so that the conical hole of the sleeve is sleeved on the battery terminal.

[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0025] A lead-acid battery lead terminal inspection tool, comprising: a fixed frame 10; a cylinder 50, which is arranged on the top of the fixed frame 10, a detection component, including a movable plate 20 fixedly arranged on the output end of the cylinder 50 and a inspection tool 30 arranged on the fixed movable plate 20, the inspection tool 30 includes a sleeve 33 and a positioning column 32 movably plugged into the top of the sleeve 33, and a conical hole for detecting the taper of the battery terminal is arranged inside the sleeve 33 and below the positioning column 32, the conical hole gradually decreases from bottom to top, and the taper is consistent with the taper of the upper part of the battery terminal; an optical fiber sensor 40, which is arranged on the top of the fixed frame 10, and the probe of the optical fiber sensor 40 is fixed on the top of the inspection tool 30, and the cylinder 50 drives the movable plate 20 to drive the inspection tool 30 to descend to detect the battery terminal.

[0026] The battery terminal is placed in the fixing frame 10 and is located directly below the inspection fixture 30. During inspection, the movable plate 20 is driven by the cylinder 50 to drive the inspection fixture 30 to descend until the conical hole of the sleeve 33 is sleeved on the battery terminal. After the battery terminal enters the conical hole, the positioning column 32 is pushed upward by the contact force. The height of the positioning column 32 is detected by the optical fiber sensor. When the height detected by the optical fiber sensor 40 is within the numerical range, the surface terminal is qualified, otherwise it means that the terminal is unqualified. This application eliminates manual inspection, realizes semi-automatic inspection, reduces labor intensity, saves working hours, and standardizes the inspection standards, improves the inspection quality, and improves the inspection efficiency.

[0027] In one embodiment, two sets of guide rods 11 are fixedly arranged in the fixed frame 10, and both ends of the movable plate 20 are slidably connected to the guide rods 11. Through the cooperation of the guide rods 11 and the movable plate 20, the problem of displacement of the movable plate 20 during the up and down movement can be effectively avoided.

[0028] In order to avoid the problem of battery terminal deviation during detection, thereby causing damage to the battery terminal, a placement groove 12 for limiting the position of the terminal is provided at the bottom of the fixing frame 10 and below the inspection fixture 30. The placement groove 12 can quickly limit and position the battery terminal.

[0029] In one embodiment, a limiting groove 321 is provided on the surface of the positioning column 32. When the limiting groove 321 is not exposed or completely exposed from the sleeve 33, Figure 4 as well as Figure 5 , it means that the battery terminal is unqualified, otherwise the surface battery terminal is qualified.

[0030] In one embodiment, two groups of movable columns 34 are symmetrically arranged on the surface of the positioning column 32 and below the limiting groove 321, and a sliding groove 331 is opened on the surface of the sleeve 33 for the movable column 34 to move up and down, which can effectively prevent the positioning column 32 from shifting during the up and down movement, thereby causing inaccurate probe measurement of the optical fiber sensor 40.

[0031] In one embodiment, the outer surface of the sleeve 33 is fixedly sleeved with a fixing seat 31, and the fixing seat 31 is fixedly connected to the moving plate 20 by bolts, and the sleeve 33 is fixed to the moving plate 20 by the fixing seat 31.

[0032] In one embodiment, a mounting track is disposed on the top of the fixing frame 10 , and the mounting track is detachably connected to the optical fiber sensor 40 , and the placement position of the optical fiber sensor 40 can be adjusted through the mounting track.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
