At present, most of alkaline manganese battery manufacturers use ring-mounting production lines which are composed of a plurality of ring-mounting machines, a battery shell feeding and conveying device, a manganese ring feeding device and the like. When the assembly production line works, the battery shell is manually queued on the hopper and then rolls down from the material channel. The battery case is conveyed by using a plurality of sets of double-crank type movable beam conveying mechanisms to lift, move forwards and fall the workpieces, and one conveying the battery case to the corresponding assembly position. The battery case is tightly pressed by a pressing block under the action of an end face cam, and then the manganese ring is pushed into the battery case by a pressure lever through a crank link mechanism.

Embodiments of the invention will be described in detail below with reference to the following drawings:

FIG. 1: front view of the invention

FIG. 2: top view of the invention

FIG. 3: front view of sheave intermittent motion mechanism

FIG. 4: back structure diagram of grooved wheel

As can be seen from fig. 1, 2, 3 and 4, the frame 1 is formed by connecting an upper support plate, a lower support plate, a front vertical plate and a rear vertical plate. The motion of the manganese ring assembling machine is transmitted to a motion distribution shaft 4 supported on a lower support plate of the frame 1 by a motor and a reducer mechanism 25, and the motion is transmitted to three directions by the motion distribution shaft 4: 1. a crank connecting rod sliding plate mechanism 22 is transmitted to a sheave intermittent motion mechanism 2 through a shifting pin 2 on a driving plate 3, and 3, the intermittent motion mechanism is transmitted to a swing rod 10 through an end face cam 5 on a motion distribution shaft 4, and then a jacking plate 12 is shifted through a shifting fork 26.

The intermittent indexing movement of the sheave intermittent movement mechanism is realized by that the pin 2 on the driving plate 3 drives the sheave 6. The pin 2 drives the grooved wheel 6 to rotate through one station every time the motion distribution shaft 4 rotates one circle. The grooved wheel 6 is not only a transmission part which moves intermittently, but also a disc-type executing part which drives the battery shell to rotate. The indexing groove 38 and the coarse positioning ball socket 8 on one end face of the sheave are used for realizing the movement indexing and the coarse positioning of the sheave, respectively. One of the large semicircular arc grooves 37 uniformly distributed on the outer edge of the grooved wheel is used as a feeding station, the other one is used as a discharging station, and the rest are ring mounting stations with the same number as that of the manganese rings mounted in the battery shell. And fine positioning holes 31 uniformly distributed on the other end surface of the grooved pulley are used for fine positioning of the grooved pulley. When the grooved wheel does intermittent motion, the arc groove 37 on the grooved wheel drives the battery shell to do feeding, ring installation, displacement and material returning actions. The sheave-mounted spindle 19 rests on the underside of the upper support plate 35 of the frame 1, supporting the sheave.

The die plate 16 is provided with die sleeves 15 with the same number as the press rods 36 on the sliding plate 18, and is provided with the same number of material grooves. Half of the die sleeve is a cylindrical hole, the end part of the die sleeve is a conical opening and is used for tightly pushing the opening end of the battery shell, and the other half of the die sleeve is in a semi-circular arc hole shape and corresponds to the trough on the die plate.

The slide plate 18 is provided with the same number of pressure bars 36 as the manganese rings to be arranged, under the action of the crank connecting rod slide plate mechanism 22, the slide plate drives the pressure bars 36 on the guide rail 20 to enter the die sleeve of the die plate 16, the manganese rings in the die sleeve are pushed to enter the battery case 14, and then the cam 5, the swing rod 10, the shifting fork 26 and the slide plate mechanism 22 are used for shifting the tightening plate 12 to tighten the battery case. When the pressure lever 36 is withdrawn from the die sleeve 15, the manganese ring accurately falls into the semicircular arc hole of the die sleeve from the trough on the die plate, and the automatic feeding process of the manganese ring is completed.

The jacking plates 12 are provided with jacking sleeves 13 with the same number as the pressing rods, and the battery cases are jacked and loosened under the action of the end face cam 5, the swing rod 10, the shifting fork 26, the sliding plate mechanism 22, the jacking plates 12 and the return spring 7. The right end of the battery case is tightly pressed on the conical surface of the die sleeve, and the left end of the battery case is tightly pressed on the shoulder of the inner hole of the pressing sleeve 13.

Thrust plate 9 is fitted with as many thrust rods 11 as there are manganese rings in the battery case. After the position of the thrust rod determines that the jacking sliding plate loosens the battery case, the jacking sleeve drives the backward movement of the battery case, and the battery case is guaranteed to be separated from the jacking sleeve 13.

The grooved wheel is positioned in a coarse and fine positioning mode. After the grooved pulley rotates by a station, a spring 7 in the template pushes the steel ball into a coarse positioning ring pit 8 uniformly distributed on the grooved pulley to perform coarse positioning on the grooved pulley. The fine positioning is to use the positioning pin 32 on the tightening plate 12, before tightening the battery case, the tightening plate drives the positioning pin to enter the positioning hole 31 uniformly distributed on the sheave, and after the fine positioning, the battery case is tightened.

The sliding plate 18 and the pressure rods 36 are in clearance fit, each pressure rod is provided with an adjusting spring 17, and the position of the pressure rod is adjusted by a pair of round nuts. Proper spring force can ensure the close contact between the manganese rings in the battery shell.

The sliding plate, the pressure lever, the jacking plate and the thrust plate are all positioned on the guide rail 20. One end of the guide rail 20 is fixed on an upper support plate of the frame 1 by a support 21, the middle section of the guide rail is supported by the template, and the other end of the guide rail is suspended. The middle section is used for supporting and guiding the sliding plate, and the overhanging section supports the jacking plate and the thrust plate and plays a role in guiding the jacking plate.

The charging and discharging of the battery shell is completed in such a way that when the grooved wheel is in the stop position, the battery shell in the material channel 27 falls into the semi-circular arc of the grooved wheel by the pressure of the upper battery shell. The sheaves index to bring the battery enclosure into the shroud 28 to the manganese ring mounting position. The material returning is realized by pulling the battery shell out of the material returning groove 29 by the shifting fork 26 under the action of the cam 5.

When the manganese ring assembling machine works, the motion distribution shaft rotates for a circle, the grooved wheel rotates for a station, the pressure rod reciprocates once, and each moving part completes one motion cycle to assemble one battery. The press rods reciprocate once, and the press rods enable the respective manganese rings to be arranged at different determined positions in the battery shell in the respective die sleeves.

When three sections of manganese rings need to be assembled in the battery shell, only three pressure rods are needed, three determined assembling stations are arranged on the intermittent grooved pulley mechanism, and three tightening sleeves are arranged on the tightening plate. When two sections of manganese rings need to be assembled in the battery shell, only 2 pressure rods are needed, the intermittent grooved pulley mechanism is provided with two determined ring installing stations, and the tightening plate is provided with two tightening sleeves. If different numbers of manganese rings need to be assembled, only a corresponding number of pressing rods are needed, and a corresponding number of stations are arranged on the sheave intermittent motion mechanism. Therefore, a pressing rod, a semicircular groove on the sheave intermittent motion mechanism and a jacking sleeve on the jacking plate can be used for replacing a ring installing machine in the prior art, namely, the sheave intermittent motion mechanism replaces three battery shell conveying devices, and the jacking plate replaces three jacking pressing plates, so that a plurality of transmission elements are reduced, and the reliability and the production efficiency of equipment are improved.
