Description

Technical Field

[0001] The invention belongs to the technical field of lead strip thickness detection devices, and in particular relates to an online lead strip thickness detection device for lead-acid battery production. Background Art

[0002] The advantage of lead-acid batteries is that the electromotive force is relatively stable during discharge, and the disadvantage is that the specific energy (electrical energy stored per unit weight) is small. Lead-acid batteries have stable working voltage, wide operating temperature and current range, can be charged and discharged for hundreds of cycles, have good storage performance (especially suitable for dry charge storage), and low cost, so they are widely used. In the production process of lead-acid batteries, the use of lead strip raw materials is indispensable, so the thickness of the lead strip needs to be tested to achieve standardized production and manufacturing.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figure 1-2 As shown, the present invention is an online lead strip thickness detection device for lead-acid battery production, which is used to measure the thickness of the lead strip 300 led out from the lead strip production device. Rollers 400 supported on the bottom side of the lead strip 300 are respectively arranged on both sides of the thickness detection device. The thickness detection device has a U-shaped frame 32, and the two open ends of the U-shaped frame 32 are respectively installed with a first detection mechanism 1 and a second detection mechanism 2 located on the upper and lower sides of the lead strip 300, and during detection, the ends of the first detection mechanism 1 and the second detection mechanism 2 are respectively against the upper and lower sides of the lead strip 300.

[0032] Specifically, Figure 3 The first detection mechanism 1 provided includes a connecting rod A13, at the end of which two connecting arms A121 with gaps are fixed, an axis A12 is connected between the ends of the two connecting arms A121, and a roller A is sleeved on the axis A12, and the roller A rotates around the axis A12, and the end of the connecting rod A13 is connected to a connecting sleeve A14 sleeved on its outer side wall; a spring A141 is provided between the connecting rod A13 and the connecting sleeve A14, and the bottom side surface of the connecting sleeve A14 is connected to a movable block A145 through a first spring 144, and a pressure sensor A147 abutting against the movable block A145 is provided on the top of the connecting rod A13.

[0033] Specifically, Figure 5The provided second detection mechanism 2 includes a connecting rod B23, and two connecting arms B221 with gaps are fixed on the top of the connecting rod B23. An axis B22 is connected between the ends of the two connecting arms B221, and a roller B is sleeved on the axis B22, and the roller B rotates around the axis B22. The end of the connecting rod B23 is connected to a connecting sleeve B24 sleeved on its outer side wall. The bottom side of the connecting sleeve B24 is connected to the bottom side of the connecting rod B23 through a plurality of telescopic elements 243. The bottom side of the connecting sleeve B24 is connected to a spring B241. A pressure sensor B242 is arranged on the bottom side of the connecting rod B23, and the end of the spring B241 is against the pressure sensor B242.

[0034] Based on the above, due to the inconvenience of the rated opening width of the U-shaped frame 32 during use, the rollers A and B are controlled to rest against the upper and lower sides of the lead belt 300 respectively during use, and at this time, the extended lengths of the first detection mechanism 1 and the second detection mechanism 2 are detected respectively.

[0035] It can be known that the sizes of the connecting rod A13 and the connecting rod B23, and the connecting sleeve A14 and the connecting sleeve B24 in the above are rated. Therefore, by detecting the distance between the connecting sleeve A14 and the connecting rod A13, and the distance between the connecting sleeve B24 and the connecting rod B23, the extension length of the first detection mechanism 1 and the second detection mechanism 2 can be obtained.

[0036] Based on the spacing detection requirements, the above-mentioned pressure sensor A147, pressure sensor B242, spring B241 and spring A141 are coordinated, and the extension length of spring A141 and spring B241 can be determined respectively by reading the pressure sensor A147 and the pressure sensor B242, and then the extension length of the first detection mechanism 1 and the second detection mechanism 2 can be determined when in use.

[0037] Specifically, the telescopic element 243 includes a micro telescopic cylinder, and the telescopic element 243, pressure sensor A147 and pressure sensor B242 are all connected to a controller.

At this time, the flexible touch rod A137 abuts against the first pressure sensor 138 to generate a pressure signal, that is, when the first pressure sensor 138 detects an intermittent pressure signal, the roller A rotates.

[0040] Specifically, Figure 4 The roller B includes a circular roller body B21, an annular groove B20 is provided in the middle of the roller body B11, and a plurality of protrusions B211 are provided on the outer peripheral side wall of the annular groove B20; the top surface of the connecting rod B23 is recessed downward to form a concave cavity B231, and a swing rod B233 is rotatably connected to the concave cavity B231 through a rotating shaft 232, and a mounting sleeve B235 is horizontally arranged in the concave cavity B131 located on one side of the swing rod B233, and a counterweight ball 234 is arranged at the bottom end of the swing rod B233; the bottom side surface of the mounting sleeve B235 is connected to a movable column B237 sliding along the inner wall of the mounting sleeve B235 through a third spring 237, and the bottom side surface of the mounting sleeve B235 A second pressure sensor 238 is arranged on the surface, and a flexible touch rod B239 is arranged at one end of the movable column B237 located in the mounting sleeve B235.

At this time, the flexible touch rod B239 abuts against the second pressure sensor 238 to generate a pressure signal, that is, when the second pressure sensor 238 detects an intermittent pressure signal, the roller B rotates.

[0041] In order to ensure that the first spring 144 can expand and contract in the vertical direction without bending, an inner guide sleeve 143 is arranged on the top of the connecting rod A13, an outer guide sleeve 142 is fixed inside the connecting sleeve A14 and is sleeved on the outside of the inner guide sleeve 143, a protrusion 146 that slides along the inner wall of the inner guide sleeve 143 is arranged on the peripheral side of the movable block A145, and a pressure sensor A147 is located inside the inner guide sleeve 143.

[0042] Specifically, the flexible touch rod A137 and the flexible touch rod B239 each include a main rod made of plastic material, and a rubber ball is provided at the end of the main rod to ensure that when the flexible touch rod A137 and the flexible touch rod B239 contact the first pressure sensor 138 and the second pressure sensor 238 respectively, the flexible touch rod A137 and the flexible touch rod B239 bend.
