There is also an apparatus for efficiently pouring an electrolyte solution into a battery container (see Patent Document 1, for example).

The above-mentioned electrolyte injection device had the following problems. That is, since the circumference | surroundings of the nozzle tip used for the injection of electrolyte solution are a decompression space, electrolyte solution is easy to flow down and the injection precision became worse. In addition, since a large number of processes are processed simultaneously in a large pressure reduction chamber, water retention and flexibility are hindered. Moreover, when a problem arises in one place, production efficiency is very bad because the whole apparatus is stopped. In particular, trouble in the decompression chamber could lead to failure of all products contained in the chamber.

Therefore, an object of the present invention is to provide a liquid injecting apparatus which is compact and has good maintenance.

It is possible. In other words, since the rod 214 rotates together with the index table 211 and the cylinder 216 is fixed to the mount 31, the rod 214 can be driven up and down only when the rod 214 is positioned directly above the cylinder 216.

As illustrated in FIG. 7, the transport container 215 is provided with an O ring 215b on the upper surface 215a. In addition, a groove 215c is formed to allow the battery container W to be inserted and to be picked up by the loader 110.

The liquid injection part 230 accommodates an electrolyte solution, and its one end is connected to the pressure reduction bubble removal tank (electrolyte tank) 231 which can decompress | restore inside, and this pressure reduction bubble removal tank 231, and is about 10 mm in diameter ( One end of the pipe 232 having a diameter of 1, a motor controlled precision discharge pump 233 connected to the other end of the pipe 232, and the precision discharge pump 233, and having a diameter of about 2 mm. Pipe 234 having a second diameter), a check valve 235 connected to the other end of the pipe 234, and a discharge nozzle 236 connected to the check valve 235 and disposed above the opening 217a. ). On the other hand, the pipe 232 is preferably as short as possible.

The impregnation part 240 is equipped with the pressure reduction chamber 241 attached to the opening part 217b. The decompression chamber 241 is configured to be able to decompress to 50 Torr, for example, at a low vacuum below the saturated vapor pressure.

The sealing part 250 includes a decompression chamber 251 attached to the opening 217c, a heater 252 accommodated in the decompression chamber 251 to heat-compress and seal the opening of the battery container W, and a heater after sealing. 252 and a knock out pin (marking device) 253 for separating the battery container W are provided. The pressure reduction chamber 251 is a low vacuum below saturated vapor pressure, and is comprised so that pressure reduction to 30 Torr is possible, for example. In addition, the knock-out pin 253 is formed at its distal end so that different markings are possible for each electrolyte injection device 30.

The electrolyte solution pouring system 10 configured as described above performs pouring as follows. At first, the conveyance carrier T which mounted the battery container W before liquid injection is conveyed by the 1st conveyance conveyor 23 of the conveying apparatus 20. As shown in FIG. Here, the conveyance carrier T is paused by the carrying-in / out part 120 of the electrolyte solution injection device 30, and the battery container W is picked up by the pick-up arm 111. FIG. The pickup arm 111 rotates in the direction of the arrow L while maintaining the battery container W, and transfers the battery container W to the preloading unit 130. On the other hand, when the pick-up arm 114 holds the battery container W after pouring, the battery container W is mounted on the transport carrier T.

The battery container W transferred to the preloading unit 130 is loaded in the guide 131. As the guide 131 descends, the bottom surface of the battery container W contacts the load cell 132, and the mass of the battery container W before pouring is measured from the output of the load cell 132, and the value is a nominal amount. It is stored in the unit 130 or the control device 40.

The battery container W in which the mass is measured is picked up by the pick-up arm 112. The battery container W is transferred to the battery container taking over part 140 by rotating in the direction of the arrow L while maintaining the battery container W. As shown in FIG.

In the battery container take over part 140, the battery container W is moved and mounted on the transport container 215 positioned in the battery container take over part 220. Next, the index table 211 rotates 90 degrees in the direction of the arrow R to reach the lower side of the discharge nozzle 236. The electrolyte is discharged from the discharge nozzle 236 under atmospheric pressure, and is injected into the battery container W held in the transport container 215.

In addition, the electrolyte solution to be injected is bubbled in a reduced pressure state of, for example, about 150 Torr which is equal to or less than the saturated vapor pressure of the electrolyte solution in advance in the reduced pressure bubble removing tank 231. Although the pressure reduction state at this time removes an internal bubble by boiling an electrolyte solution, it is a thing of the grade which does not suddenly boil and suddenly depressurizes.

Electrolyte solution is sent out from the pressure reduction bubble removal tank 231 by the precision discharge pump 233 with high precision. Since the inner diameter of the pipe 232 between the pressure reduction bubble removal tank 231 and the precision discharge pump 233 is large, the flow velocity of electrolyte solution becomes small. For this reason, since generation | occurrence | production of a bubble is suppressed and a bubble becomes easy to return to the pressure reduction bubble removal tank 231 in the pipe 232, the quantity sent by the precision discharge pump 233 can be adjusted with high precision. do.

In addition, the electrolyte is sent from the precision discharge pump 233 to the check valve 235. At this time, bubbles inside the electrolyte are sent to the check valve 235 at the same time as the electrolyte. Since the inner diameter of the pipe 234 between the precision discharge pump 233 and the check valve 235 is small, the flow rate of electrolyte solution becomes large. For this reason, it becomes possible to discharge the produced | generated bubble from the discharge nozzle 236 at once.

The check valve 235 opens the valve against the elastic force only when the pressure of the electrolyte solution sent from the precision discharge pump 233 is above a certain level, and the electrolyte solution is sent out. Therefore, when the precision discharge pump 233 stops, the valve is closed by the elastic force to stop the discharge of the electrolyte, and high precision pouring can be performed without leaking the remaining electrolyte in the discharge nozzle 236. Moreover, since the bubble in electrolyte solution can be suppressed to the minimum, it is possible to minimize the flow of the liquid in the discharge nozzle 236, and to reduce the fluctuation of the amount of pouring liquid.

When the electrolyte is discharged by a predetermined amount, the cylinder 216 is operated and the rod 214 is lowered. The index table 211 rotates in the lowered state, and the battery container W is transferred to the impregnation part 240. In the impregnation part 240, the rod 214 is raised by the cylinder 216, and the upper surface 215a of the transport container 215 contacts the lower surface of the fixing plate 217. At this time, the inside of the decompression chamber 241 is hermetically sealed by the O-ring 215b. Here, the pressure reduction chamber 241 is depressurized to about 50 Torr, for example, so that the electrolyte solution does not overflow, and bubbles are removed and the electrode is impregnated in the pressure reduction chamber 241. Next, the inside of the decompression chamber 241 is returned to atmospheric pressure.

After a predetermined time has elapsed, the cylinder 216 is operated and the rod 214 is lowered. The index table 211 rotates in the lowered state, and thus the battery container W is transferred to the sealing part 250. In the seal 250, the rod 214 is raised by the cylinder 216, and the upper surface 215a of the transport container 215 contacts the lower surface of the fixing plate 217. At this time, the inside of the decompression chamber 251 is hermetically sealed by the O-ring 215b.

In the decompression chamber 251, heat pressing of the opening of the battery container W is performed by the heater 252, thereby sealing. At this time, in order to prevent the heater 252 from sticking to the battery container W, the heater 252 and the battery container W are sandwiched by a knockout pin 253 slightly below the sealed position. Disconnect. On the other hand, the knock-out pin 253 is unique to each electrolyte injection device 30, so that, for example, depending on the number of irregularities, the shape of the stamp, and the like, each battery container W has a certain electrolyte injection device 30. ), It is possible to know whether the pouring and sealing was done. That is, when a defective product arises for some reason, it becomes possible to specify the electrolyte solution pouring apparatus 30 which a defective product generate | occur | produces after imprinting by the battery container W after maintenance, and to perform maintenance and adjustment. .

Next, the cylinder 216 is operated and the rod 214 is lowered. The index table 211 rotates in the lowered state, and the battery container W is transferred to the battery container taking over part 220. By the pick-up arm 113, the battery container W is picked up from the transport container 215, the pick-up arm 113 rotates in the direction of the arrow R, and the battery container W is transferred to the post weighing unit 150. do.

In the post weighing unit 150, the mass of the battery container W is measured in the same manner as in the preloading unit 130. At this time, when the measurement result is out of a predetermined allowable range by comparing with the mass of the liquid injection stored in the preloading unit 130 or the control device 40, the guide 151 is used by using the discharge chuck 155. ), And is recovered in the defective product discharging unit 154. On the other hand, by feeding back a measurement result to the control apparatus 40, it is possible to adjust the discharge amount from the precision discharge pump 233, and to reduce the incidence rate of a defective product.

When the weight of the battery container W is prescribed and determined to be good quality, it is picked up by the pick-up arm 114 and conveyed to the carrying-in / out part 120. In the carry-in / out part 120, the battery container W after pouring is mounted in the empty conveyance carrier T, it is conveyed by the 2nd conveyance conveyor 24, and is sent to the discharge part 22. As shown in FIG.

In the discharge part 22, the battery container W is taken out of the conveyance carrier T, and is sent to a subsequent process. The empty conveyance carrier T is returned to the supply part 21 by the 3rd conveyance conveyor 25.

As described above, in each electrolyte injection device 30 of the electrolyte injection system 10, the maintainability of the device is improved, so that the electrolyte solution can be injected into the battery container W with high precision and high efficiency, resulting in a defective product. Can be suppressed to a minimum.

The present invention provides a weighing meter that needs to be disposed below the gravity direction of the battery container in order to measure weight, and an injection system that needs to be disposed above the gravity direction of the battery container in order to inject and seal the electrolyte solution into the battery container. It divided into two types of carrier systems. For this reason, the apparatus structure is simplified, and the whole pouring apparatus can be miniaturized. By miniaturization, it reaches the size of reachable range by reaching out to every corner in the apparatus, and can perform maintenance processing, such as repair, repair, and cleaning, without disassembling the apparatus as much as possible, and maintainability is improved.

In addition, the conveyance of the two systems of the weighing system and the injection system are each configured by the rotary motion system, and the battery container is disposed on the path of the rotary motion, thereby further miniaturizing the apparatus.

In the weighing system, the chuck mechanism oscillated in the rotary motion system is dedicated to import and export, respectively. For this reason, the rotational motion system becomes a rocking motion in a range of 180 ° without rotating. For this reason, the wiring process of the drive source for driving a chuck becomes easy, and maintainability is improved. Since the injection system does not have a chuck mechanism, the injection system is rotated.

In the injection system, the carrier holding the battery container is configured to be transported under a fixed table plate, and a unit for carrying out pouring, bubble removal, and sealing is disposed on the upper side of the table plate, and the through hole provided in the table plate is placed. Through this process, each process is performed. For this reason, an injection system can be divided into a gravity direction upper limit processing system and a conveyance system via a table plate, and maintenance property is improved.

Moreover, since the O-ring provided in the conveyer was made to contact a table plate to form a vacuum chamber, it was not necessary to remove a battery container from a conveyer every time, and the throughput was improved.

In addition, by dividing the processing system of the injection system into three steps of pouring, impregnation, and sealing, and configured to be performed through different through-holes of the table plate, the unit in charge of each process can be miniaturized. In addition, especially in the impregnation and sealing process, the vacuum chamber must be formed, but since the unit can be downsized, the vacuum chamber can also be downsized, and the speed at which the vacuum is removed is improved, thereby increasing the throughput. On the other hand, the impregnation process can be omitted at the time of sealing at the time of sealing by balance with the tact time required for the pouring process.

In addition, the conveyance direction of the battery container W becomes counterclockwise in the weighing mechanism part 100 and clockwise in the liquid filling mechanism part 200, so that 8 characters are drawn. For this reason, it becomes possible to suppress the interference of the conveyance of the battery container W by the loader 100 and the conveyance of the battery container W by the index table 211 to the minimum.

On the other hand, in consideration of the fact that there are processes such as depressurization, impregnation, and return to atmospheric pressure in the decompression chamber and taking time, the two battery containers W are treated at the same time. This is due to the fact that the processing efficiency is better than that of one by one, and that three or more make the arrangement and driving apparatus of each processing apparatus complicated, and the whole apparatus becomes large and maintenance becomes difficult.

In addition, in the pouring mechanism 200, each processing in the pouring portion 230, the impregnation portion 240, and the sealing portion 250 is performed in the vicinity of the fixing plate 217 provided above the index table 211. It is. For this reason, there exists an advantage that maintenance is easy.

On the other hand, the electrolyte solution pouring system 10 can continue the pouring process in the other electrolyte pouring device 30 even when the electrolyte pouring device 30 is temporarily stopped due to breakdown, repair, or modification. The fall of the operation rate as a line can be prevented without stopping. In addition, it is possible to have the flexibility that the expansion or reduction of the device can be selected in accordance with the production capacity of the production line.

In addition, this invention is not limited to the said embodiment. That is, although three electrolyte solution injection apparatuses 30 were used in said embodiment, it is not limited to three. Moreover, although the impregnation part was provided in the pouring mechanism part, it can also be abbreviate | omitted according to the time required for pouring and sealing which are other processes. The operating direction of the loader 110 and the rotating direction of the index table 211 are not limited to the above. Moreover, it is possible to use even if a battery container is supplied and extracted by an operator as a unitary apparatus instead of automatic in-line. In addition, various modifications can be made without departing from the scope of the present invention.

According to the present invention, it is possible to inject the electrolyte solution with high precision, and also to be compact and maintainable, and to improve the production efficiency.
