Description

Technical Field

[0001] The invention belongs to the technical field of lead strip production detection, and in particular relates to an online lead strip thickness detection system for 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.

[0003] For example, CN215902480U discloses a flattening device for lead tape, and CN118533529A discloses a lead tape sampling device. In the above-mentioned existing documents, the lead tape is often cut and then a thickness detection device is used to detect the thickness of the lead tape during use. This detection is prone to cause the lead tape to warp due to cutting, which affects the measurement accuracy of the lead tape. At the same time, online detection cannot be performed, and sampling is required during detection, which destroys the overall structure of the lead tape. In addition, this sampling-type detection cannot detect the thickness of the lead tape in real time during use. Summary of the invention

[0028] See also Figure 1-3 As shown, the present invention is an online lead strip thickness detection system for battery production, which includes a mounting frame, on which a detection mechanism A and a detection mechanism B are arranged relatively, and when in use, the lead strip 100 drawn out from the lead strip production device is controlled to pass through the gap formed by the detection mechanism A and the detection mechanism B; at the same time, the detection mechanism A and the detection mechanism B respectively include a detection rod A2 and a detection rod B3 with measurable telescopic lengths, a roller A202 is installed at the end of the detection rod A2, and a roller B302 is installed at the end of the detection rod B3; when installed, the roller A202 and the roller B302 are respectively against the upper and lower surfaces of the lead strip 100, and rotate under the conveying action of the lead strip 100; and then when in use, after driving the rollers A202 and B302 to rotate respectively, by detecting the extended lengths of the detection rod A2 and the detection rod B3, the gap width between the rollers B302 and A202 is obtained, and finally the lead strip thickness is detected.

[0029] In order to facilitate the detection, Figure 5 The detection rod A2 provided by the present invention comprises an outer sleeve A21, the inner bottom side of the outer sleeve A21 is connected to a movable rod A22 through a spring A217; the movable rod A22 is provided with a plug hole 222 on the end surface inside the outer sleeve A21, the bottom side of the plug hole 222 is connected to a push rod 221 through a spring B223, a guide sleeve 218 matched with the push rod 221 is fixed to the inner bottom side of the outer sleeve A21, a pressure sensor A219 is arranged in the guide sleeve 218, and a notch A201 is arranged at the end of the movable rod A22, and the notch A20 Mounting holes A203 for mounting roller A202 are respectively provided on the two inner side walls of 1, and then in the natural state, the spring A217 and the spring B223 are both in the stretched state, and the end of the push rod 221 is detached from the pressure sensor A219, that is, during installation, the control roller A202 is against the upper surface of the lead belt 100, and the spring A217 and the spring B223 are in relative contraction compared to the natural state, and the end of the push rod 221 is against the pressure sensor A219, and the pressure sensor A219 generates a signal.

[0030] At the same time Figure 6The detection rod B3 provided by the present invention includes an outer sleeve B31, and the inner bottom side surface of the outer sleeve B31 is connected to the movable rod B32 through a spring C33; the opposite side walls of the outer sleeve B31 and the movable rod B32 are respectively provided with a vertical rod A36 and a vertical rod B37, and the ends of the vertical rod A36 and the vertical rod B37 are respectively bent inward to form a cross bar A361 and a cross bar B371; the cross bar B371 is located directly above the cross bar A361; a guide cylinder 362 is provided on the upper surface of the cross bar A361, and the bottom side surface of the guide cylinder 362 is connected to a guide rod 364 through a spring D363, and the top end of the guide rod 364 is against a pressure sensor B372, and The pressure sensor B372 is installed on the lower surface of the cross bar B371; a slot B3011 is set at the end of the movable rod B32, and mounting holes B302 for mounting the roller B302 are respectively set on the two inner walls of the slot B301; then in the natural state, the spring C33 is in compression, and the spring D363 is in tension, and then at this time, the top pressure sensor B372 of the guide rod 364 is on; when the roller B302 is against the lower surface of the lead belt 100, it is in a natural state at this time, the spring C33 is in relative compression, and the spring D363 is in considerable tension; at this time, the pressure signal detected by the pressure sensor B372 is small.

[0031] Through the above arrangement, when the lead tape 100 is controlled to pass through the gap formed by the detection mechanism A and the detection mechanism B, and drives the roller B302 and the roller A202 to rotate, the extended length of the detection rod A2 and the detection rod B3 can be obtained at this time. Under the premise that the installation spacing between the detection rod A2 and the detection rod B3 is certain, the gap width between the roller B302 and the roller A202 can be obtained at this time.

[0032] Specifically, the outer sleeve B31 and the movable rod B32 are provided with sleeves A35 and sleeves B34 respectively on the opposite side walls thereof, which are sleeved and matched with each other.

Through the setting of the pin rod 39, the movable rod B32 is controlled to retract into the inner part of the outer sleeve B31 or maintain the state unchanged during use.

[0034] At the same time, in order to facilitate the control of the movable rod A22 when in use, after being stored in the outer sleeve A21, the state remains unchanged after the external force is removed, such as Figure 4A movable rod 212 is rotatably connected to the outer wall of the outer sleeve A21 through a rotating shaft 211, a hook 213 is provided at the end of the movable rod 212, and a T-shaped column 221 cooperating with the hook 213 is provided on the outer wall of the movable rod A22; when in use, after controlling the movable rod A22 to be stored inside the outer sleeve A21, the movable rod 212 is rotated until the hook 213 is cooperating and hooked on the position of the T-shaped column 221, and after the external force is removed, the hook 213 is hooked on the T-shaped column 221.

[0035] In order to limit the position of the movable rod A22, a limit block A214 and a limit block B215 are respectively arranged on the outer side walls of the outer sleeve A21 on both sides of the movable rod 212; the limit block B215 is elliptical and can be threadedly installed on the outer side wall of the outer sleeve A21, and an operating block 216 is arranged on the outer side wall of the limit block B215.

[0036] It can be known that the installation of the detection rod A2 and the detection rod B3 is convenient during use, and the distance between the two mounting beams 14 after installation can be controllably adjusted. Then, when in use, the distance between the two mounting beams 14 is L. When the detection rod A2 and the detection rod B3 are extended to L1 and L2 respectively, the gap width between the roller B302 and the roller A202 is L3, and L3=L-L1-L2.

[0037] That is, the mounting frame includes a horizontally arranged crossbeam 1, and the two sides of the crossbeam 1 are connected with mounting beams 14 through telescopic rods, and the detection rod A2 and the detection rod B3 are respectively arranged at the ends of the two mounting beams 14; scale rods 15 are respectively arranged on both sides of the crossbeam 1, and an indicator sleeve 16 sleeved on the scale rod 15 is arranged on one side of the mounting beam 14; the telescopic rod includes a rod sleeve 11 and a rod body 13 that cooperate with each other, and a locking bolt 12 is arranged at the end of the rod sleeve 11.
