Description

Technical Field

[0001] The utility model belongs to the technical field of storage batteries, and in particular relates to an automatic quantitative lead adding tool for double-side cladding terminals. Background Art

[0002] Lead-acid batteries are widely used in industries such as industry and transportation. Lead-acid batteries need to be assembled during the production process, including terminal welding. Since the discharge current of commercial vehicle batteries is large, conventionally welded terminals are prone to terminal (pole) melting during use, so cladding terminals are often used.

[0003] The current cladding terminal is semi-automatic welding: the equipment welds the large lead ring and the pole together, and then manually adds lead and welds it into shape to complete the welding process. Manual welding is inefficient

[0004] In the existing cladding terminal equipment, the lead adding tooling is to push the lead wire forward by extruding it, that is, to add lead while repairing the welding (simulating the manual welding method). The welding time is long and the high temperature will cause the plastic around the lead ring to soften, affecting the appearance and air tightness. At the same time, the initial lead adding position plane at the bottom is not cooled in time, which will cause liquid lead to drip onto the battery cover and damage the cover. In addition, the current lead adding method is to add lead on one side, the lead adding process is inefficient, and the weight of the lead wire is difficult to control. Summary of the invention

[0005] The purpose of the utility model is to solve the deficiencies of the above-mentioned prior art, thereby providing a double-sided automatic quantitative lead adding tooling for cladding terminals, which adds lead from opposite sides at the same time, improves the lead melting efficiency, ensures the uniformity of lead adding and the stability of lead wire weight, and improves welding quality.

[0006] The technical solution of the utility model is: an automatic quantitative lead adding tool for double-side cladding terminals, including an unwinding device;

[0007] The unwinding devices are two and symmetrically arranged at both ends of the quartz crucible;

[0008] Each of the unwinding devices comprises a lead wire disc fixed to the upper end of the column, and an upper guide roller and a lower guide roller are provided at one end of the lead wire disc;

[0009] A conveying device and a cutting knife module are sequentially arranged between each unwinding device and the quartz crucible along the unwinding direction;

[0010] The conveying device includes a driving roller and a driven roller arranged side by side;

[0011] The lead wire led out of the lead wire disc passes around the upper guide roller and the lower guide roller in sequence, passes between the driving roller and the driven roller, and then enters the quartz crucible.

[0012] The upper guide roller, the lower guide roller, the driving roller and the driven roller are fixed at both ends between two side-by-side vertical plates via seat bearings.

[0013] One end of the active roller is provided with a synchronous pulley, and the synchronous pulley on the active roller is connected with another synchronous pulley installed on the output shaft of the servo motor via a synchronous belt.

[0014] The upper guide roller and the lower guide roller are arranged in a left-right staggered manner, and the distance between the lower guide roller and the lead wire disc is smaller than the distance between the upper guide roller and the lead wire disc.

[0015] The cutter module comprises a cutter and a cylinder for driving the cutter to rise and fall. The cylinder barrel of the cylinder is fixed on a crossbar, and the crossbar is supported between two vertical plates.

[0016] A plurality of lead wire positioning plates are evenly distributed between the conveying device and the unwinding device. The lead wire positioning plates are fixed side by side between the two vertical plates. The lead wire positioning plates are provided with through holes for the lead wire to pass through. The gap between the active roller and the driven roller is at the same height as the through hole.

[0017] It also includes a weighing sensor and a controller for receiving the weighing sensor signal and controlling the servo motor of the conveying device and the cylinder action of the cutter module. The weighing sensor is arranged between the unwinding device and the conveying device on either side, and the upper end of the weighing sensor is in contact with the lead wire.

[0018] Compared with the prior art, the advantages of the utility model are:

[0019] 1. Single-sided lead adding is changed to double-sided lead adding, the lead wire is thinner and the lead adding is more uniform, which is beneficial to weight control and lead melting, ensuring the uniformity of lead adding and the stability of lead wire weight, and improving welding quality.

[0020] 2. The lead wire weight control is changed from length control to sensor-induced weight control, which is more accurate;

[0021] 3. Adding unwinding structure can eliminate stress and make the lead wire straighter, which is beneficial to improving weight control accuracy. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] like Figure 1 As shown, the unwinding device includes a column 1, a lead wire disc 2 fixed on the column, the lead wire disc 2 is used to install the lead wire roll, an upper guide roller 3 and a lower guide roller 4 are provided at one end of the lead wire disc 2, and the upper guide roller 3 and the lower guide roller 4 are respectively fixedly connected to the corresponding vertical plate 10 through a seat bearing, and the two vertical plates 10 are arranged side by side front and back, and the upper guide roller 3 and the lower guide roller 4 are arranged in a staggered manner left and right, and the distance between the lower guide roller 4 and the lead wire disc 2 is smaller than the distance between the upper guide roller 3 and the lead wire disc 2. Two unwinding devices are symmetrically arranged at both ends of the quartz crucible 7, and a conveying device and a cutter module are sequentially provided between the unwinding device and the quartz crucible 7 along the unwinding direction. The cutter module is used to cut the lead wire, and the cutter module includes a cutter 6 and a cylinder 5 for driving the cutter 6 to rise and fall, and the cylinder barrel of the cylinder 5 is fixed on a crossbar 11, and the crossbar 11 is supported between the two vertical plates 10. Two lead wire positioning plates 15 are evenly arranged between the conveying device and the unwinding device. The two lead wire positioning plates 15 are fixed side by side between the two vertical plates 10. There are through holes on the two lead wire positioning plates 15 for the lead wire to pass through. The conveying device includes a driving roller 8 and a driven roller 9 arranged side by side. The gap between the driving roller 8 and the driven roller 9 is at the same height as the through hole. The two ends of the driving roller 8 and the driven roller 9 are fixed between the two side by side vertical plates 10 through seat bearings. One end of the driving roller 8 of the two conveying devices is provided with a synchronous pulley. The synchronous pulleys on the two driving rollers 8 are respectively connected to the other two synchronous pulleys installed on the output shaft of the servo motor 14 through the synchronous belt 13. The lead wire drawn from the lead wire disc 2 bypasses the upper guide roller 3 and the lower guide roller 4 in turn, passes between the driving roller 8 and the driven roller 9, and then enters the quartz crucible 7.

[0025] In another embodiment, if Figure 1As shown, a weighing sensor 12 is provided between the unwinding device and the conveying device on either side, and the weighing sensor 12 is fixed between the two vertical plates 10 via a bracket (not shown in the figure), and also includes the weighing sensor 12 and a controller for receiving the weighing sensor 12 signal and controlling the servo motor 14 of the conveying device and the cylinder 5 of the cutter module. The weighing sensor 12 adopts a spoke-type weighing sensor, and the specification is Shanghai Quality Exhibition Measurement and Control ZZ310-105D.

[0026] When in use, the servo motor runs, and the lead wire passes through the spoke-type weighing sensor and enters the crucible. At this time, the terminal welding machine is ignited, and the lead wires on the left and right sides are added and melted. When the weight of the lead wire passing through the spoke-type weighing sensor reaches the required value (because the lead wires on both sides are driven by a set of servo motors to rotate synchronously and feed, the required value should be half of the weight required for terminal welding), after the required delay time, the servo motor stops rotating, the cutter module cuts the lead wire, and the lead wire addition stops. The terminal welding machine pours the molten lead liquid in the crucible into the terminal mold, cools and forms it, and completes the surfacing.
