The chuck part 1140 (1) of FIG. 1 illustrates a configuration having three pairs of clip-like electrode structures.

  In FIG. 8, only the chuck portions 1140 (1) to 1140 (4) are shown for convenience of explanation, but this corresponds to the number of stacked thin secondary batteries 41 constituting the secondary battery 2150 to be chucked. It is assumed that up to the number (n) of chuck portions 1140 (n) are provided. A detailed configuration of the chuck electrode 1141 of the chuck portion 1140 shown in FIG. 8 will be described later with reference to FIG.

  Further, FIG. 9 shows that a magazine 7131 (corresponding to the secondary battery 2150) in which a plurality of thin secondary batteries 41 to be subjected to a charge / discharge test is accommodated is conveyed to a test position of the charge / discharge test apparatus 1100 by a conveyor or the like. After that, the chuck portion 1140 is a diagram illustrating a state in which the electrode terminals 65 and 67 are chucked.

  As can be understood from FIG. 9, the electrode terminals 65 and 67 of each thin secondary battery 41 are disposed so as to face the corresponding chuck portions 1140, respectively, and then the electrode terminals 65 and 67 to which the chuck portions 1140 correspond. It is pressed with a clip-shaped electrode so as to sandwich it. When the chuck portion 1140 presses with the clip-shaped electrodes so as to sandwich the electrode terminals 65 and 67, the aluminum oxide thin film covering the electrode terminals 65 and 67 is broken, and electrical connection is ensured. After that, a predetermined charge / discharge test is performed.

  FIG. 10 is a conceptual diagram for explaining an outline of the enlarged configuration of the chuck electrode 1141, (a) is a perspective view of the chuck electrode 1141, and (b) is an AA ′ sectional view of the chuck electrode 1141.

  As can be understood from FIG. 10, the chuck electrode 1141 includes a plurality of chuck electrode needles 1142 having a height of about several hundred microns. When the chuck portion 1140 is chucked, the chuck electrode needle 1142 breaks through the aluminum oxide film on the electrode terminals 65 and 67, thereby realizing electrical conduction between the chuck electrode 1141 of the chuck portion 1140 and the electrode terminals 65 and 67. Is done.

  For this reason, in the charge / discharge test apparatus 1100 for sequentially charging / discharging a large number of secondary batteries 2150, a small amount of aluminum oxide dust generated when the aluminum oxide film is broken adheres to the chuck electrode 1141 and is gradually stacked. The Due to such dust and the like, the function of the chuck electrode needle 1142 to break through the aluminum oxide film is reduced, or the electrical continuity between the chuck electrode 1141 and the electrode terminals 65 and 67 is hindered. There is a concern that the charge / discharge test may not be performed.

  In order to eliminate such concerns, the automatic cleaning unit 1200 according to the present embodiment performs automatic cleaning of the chuck electrode 1141 and the like as appropriate at an appropriate timing, thereby ensuring stable and reliable electrical conduction at all times. A desired charge / discharge test can be performed.

  FIG. 11 is a conceptual diagram illustrating and explaining a variation of the cleaning terminal 11220 connected to the ultrasonic vibration element 11210. FIG. 11 (a) shows a cleaning terminal 11220 (a) composed of a cleaning sheet, and FIG. 11 (b) shows a cleaning terminal provided with dimples 11221 that are in contact with the chuck electrode needle 1142 and that are provided with an abrasive on at least the inner wall. 11C shows the chuck electrode needle 1142 by maintaining the vibration space of the cleaning brush 11222 while the tip of the chuck electrode needle 1142 secures the base of the cleaning terminal 11220 (c) and the space. FIG. 11D shows a cleaning terminal 11220 (c) provided with a spacer 11223 configured such that the tip or the like is effectively cleaned by the cleaning brush 11222, and FIG. 11D shows a cleaning terminal 11220 (c) provided with the spacer 11223 and a chuck electrode. It is a conceptual diagram explaining the positional relationship of the needle 1142. FIG.

  In FIG. 11 (a), the cleaning terminal 11220 (a) composed of a cleaning sheet is attached to the surface by applying or spraying abrasive on a sheet-like relatively hard nonwoven fabric, solidified paper or soft resin, etc. It can be set as the structure made to. The abrasive may be contained and impregnated not only on the surface but also on the material itself. 11A shows only the cross-sectional shape, the cleaning terminal 11220 (a) formed of a cleaning sheet may be circular so as to correspond to the shape of the chuck electrode 1141.

  Further, in FIG. 11A, the cleaning sheet is formed by coating or pasting the cleaning terminal 11220 (a) on the base material, that is, the cleaning terminal 11220 (a) is at least of the base material and the cleaning sheet. You may comprise as a two-layer structure.

  The cleaning terminal 11220 (a) in FIG. 11 (a) preferably has a hardness that allows the tip of the chuck electrode needle 1142 to slightly enter the cleaning terminal 11220 (a) by the pressing force that is pinched during chucking. Is preferred. With the tip of the chuck electrode needle 1142 slightly entering the cleaning terminal 11220 (a), the cleaning terminal 11220 (a) connected to the ultrasonic vibration element 11210 (a) ultrasonically vibrates, so that the aluminum oxide film It is possible to effectively clean and polish the periphery including the tip portion of the chuck electrode needle 1142 to be broken. Accordingly, even if the tip of the chuck electrode needle 1142 is worn due to a long test operation, the sharp tip can be regenerated.

  Further, as shown in FIG. 11B, the cleaning terminal 11220 (b) connected to the ultrasonic vibration element 11210 (b) includes a plurality of dimples 11221 arranged to face the chuck electrode needle 1142. May be. The shape of the dimple 11221 can be formed to have a mortar-like desired taper angle so as to correspond to the shape of the chuck electrode needle 1142. Thereby, the tip of the chuck electrode needle 1142 and the peripheral portion thereof (typically, the entire portion facing the dimple 11221 of the chuck electrode needle 1142) can be effectively cleaned and polished.

  The cleaning terminal 11220 (b) may be formed of a synthetic resin containing various rubbers, and is preferably formed of a flexible member such as a soft rubber containing an abrasive or having an abrasive on the surface. Accordingly, it is possible to apply relatively easy and flexible ultrasonic vibration to the chuck electrode needle 1142 without applying excessive stress or unexpected excessive vibration to the chuck electrode needle 1142.

  Further, as illustrated in FIGS. 11B and 11C, the cleaning terminal 11220 (c) connected to the ultrasonic vibration element 11210 (c) includes a plurality of brushes 11222 implanted in the base. Further, a spacer 11223 appropriately disposed between the plurality of brushes 11222 may be provided. The spacer 11223 is arranged at a position not facing the chuck electrode needle 1142.

  The plurality of brushes 11222 are extremely effective for removing dust and the like adhering to the chuck electrode needle 1142 and the chuck electrode 1141 by vibration of the ultrasonic vibration element 11210 (c), and contain abrasives and cleaning agents. It may be attached.

  Further, when the spacer 11223 is provided, as shown in FIG. 11D, the tip of the chuck electrode needle 1142 is not brought into contact with the base of the cleaning terminal 11220 (c) during chucking, thereby ultrasonically vibrating. Effective cleaning and polishing can be performed by bringing the brush 11222 and the chuck electrode needle 1142 into wide contact with each other.

  In the above description of the embodiment, the term “cleaning” may include the concept of polishing. In some cases, it is preferable to perform the polishing of the chuck electrode needle 1142 along with the cleaning of the chuck electrode 1141, and in some cases, a substantial amount of polishing is often performed along with the cleaning.

  Although not shown in FIG. 11, a suction nozzle that prevents reattachment of dust and the like removed from the chuck electrode 1141 during cleaning and efficiently collects the dust may be disposed in the vicinity of the cleaning terminal 11220. .

  The automatic cleaning unit of the present invention is an automatic cleaning unit that cleans a chuck portion of a charge / discharge test apparatus that is electrically connected to an electrode terminal of a secondary battery to be tested, and has the same arrangement as the electrode terminal of the secondary battery. A terminal, an ultrasonic vibration element that vibrates the cleaning terminal, and a battery for an automatic cleaning unit that supplies power to the ultrasonic vibration element so that a plurality of secondary batteries can be continuously and sequentially tested on a test line. In addition, the cleaning terminal is configured with a casing having the same shape as the secondary battery, and the cleaning terminal is in contact with the chuck part instead of the electrode terminal of the secondary battery, and the chuck part is cleaned by vibration of the ultrasonic vibration element. And

  Thereby, the automatic cleaning unit appropriately mixed in the secondary battery can automatically clean the chuck portion of the charge / discharge test without stopping the test line.

  The automatic cleaning unit according to the present invention is preferably configured such that when the charge / discharge test device continuously performs a charge / discharge test sequentially in units of magazines in which a plurality of secondary batteries are arranged in parallel, It is characterized by comprising a casing having the same shape.

  As a result, even in a charge / discharge test apparatus that simultaneously performs a charge / discharge test on a large number of secondary batteries stored in a magazine, an automatic cleaning unit configured in the same housing as the magazine can flow through the test line. It becomes possible to automatically clean the chuck part of the discharge test.

  Further, the automatic cleaning unit of the present invention more preferably includes a wireless communication slave that performs wireless communication with a charge / discharge test apparatus. In the automatic cleaning unit of the present invention, more preferably, the ultrasonic vibration element vibrates the cleaning terminal in contact with the chuck portion based on a condition instructed from the charge / discharge test apparatus via the wireless communication slave unit. It is characterized by.

  As a result, an automatic cleaning that receives an instruction from the charge / discharge test apparatus side regarding various cleaning conditions such as cleaning time, ultrasonic vibration intensity, ultrasonic vibration pattern, etc., and performs automatic cleaning of an appropriate chuck portion based on the instruction. A unit can be realized.

  Further, the automatic cleaning unit of the present invention more preferably includes an automatic cleaning unit notifying unit for notifying a charge / discharge test apparatus that an object to be connected to the chuck unit is not a secondary battery but an automatic cleaning unit. To do. The automatic cleaning unit according to the present invention is more preferably characterized in that the charge / discharge test apparatus is in a sleep state based on a notification from the automatic cleaning unit notification unit while the chuck unit is being cleaned.

  As a result, the automatic cleaning unit can accurately notify the charge / discharge test apparatus that it is not the charge / discharge test target (that is, the secondary battery to be tested). Running voltage can be reduced by contributing to low power consumption, such as not having to prepare voltage and current for the discharge test.

  The automatic cleaning unit of the present invention is more preferably characterized in that the cleaning terminal has an abrasive at a contact portion with the chuck portion. As a result, it is possible to more effectively remove deposits adhering to the chuck portion such as aluminum oxide which is an insulating film of the electrode terminal of the secondary battery, and more reliably ensure good electrical contact after cleaning. It becomes possible.

  The automatic cleaning unit of the present invention is more preferably characterized in that the cleaning terminal includes a brush for cleaning the chuck portion. Thereby, since the brush vibrates ultrasonically, an effect of cleaning the chuck portion more effectively in a short time can be obtained.

  In addition, even when the chuck portion has a plurality of needle-like convex portions, the brush is in proper contact over the entire depth direction from the tip including the tip of the needle-like convex portion to the root of the convex portion. As a whole, cleaning can be performed so that no residue remains without excess or deficiency. In addition, the acicular convex part with which a chuck part is provided breaks aluminum oxide which is an insulating thin film provided in each electrode terminal of a secondary battery as a protective film which protects the electrode of a secondary battery, and acquires electrical connection In order to do so, it may be provided in the chuck portion.

  In the automatic cleaning unit of the present invention, it is more preferable that the cleaning terminal includes a spacer facing between the needle portions of the chuck portion. Thus, when the chuck portion chucks the cleaning terminal, the contact strength and position of the brush tip with the chuck portion and the relative positional relationship between the position of the needle of the chuck portion and the cleaning terminal are restricted by the spacer. Therefore, for example, it can be prevented that the tip of the brush is excessively pressed against the chuck portion and the ultrasonic vibration is inhibited.

  In order for the brush to exhibit its cleaning effect to the maximum extent, it is preferable that the tip of the brush can be appropriately ultrasonically vibrated by the ultrasonic vibration transmitted from the base of the brush. For this reason, when the tip of the brush is excessively pressed against the chuck portion, there is no room for ultrasonic vibration of the tip of the brush, and there is a concern that a sufficient cleaning effect cannot be obtained. It can be expected that the above-described spacer provides a space that prevents the tip of the brush from being excessively pressed against the chuck portion. Further, the spacer is preferably formed of an elastic body such as rubber or a spring, and is preferably adjusted so that the tip of the brush can be vibrated ultrasonically in relation to the pinching force when chucking.

  The automatic cleaning unit of the present invention is more preferably characterized in that the height of the spacer is higher than the height of the needle so that the tip of the needle does not contact the root member of the brush. As a result, the tip of the needle portion effectively contacts the brush and can be cleaned by the ultrasonic vibration.

  According to the configuration of the embodiment, the root member of the brush is also ultrasonically vibrated like the brush, but when paying attention to the cleaning effect of the tip portion of the needle portion, in particular, the tip of the brush and the needle portion. In relation to the portion, it is preferable that ultrasonic cleaning is performed with a brush. For this reason, by appropriately adjusting the height of the spacer, the tip of the needle part can be brought into contact with the brush instead of the base member of the brush so that it floats to the extent that it does not contact the base member in a chucked state. To do.

  In the automatic cleaning unit of the present invention, it is more preferable that the cleaning terminal includes a dimple that fits with the needle portion of the chuck portion. As a result, not only the tip of the needle part of the chuck part but also the peripheral part of the line end part can come into contact with the inner wall of the dimple, and the needle part including the tip part is cleaned by the inner wall of the dimple that vibrates ultrasonically. Is possible.

  Such a dimple and the cleaning terminal including the dimple can be formed of an elastic body such as rubber. By forming the cleaning terminal and dimples with an elastic body such as rubber, it is possible to prevent excessive load or unexpected pressing force from being applied to the chuck part even when the cleaning terminal vibrates ultrasonically, safely and effectively. Appropriate cleaning can be performed.

  The automatic cleaning unit of the present invention is more preferably characterized in that an abrasive is provided on the inner surface of the dimple. As a result, the abrasive polishes the needle part including the tip part, so that dust such as aluminum oxide adhering to the tip part of the needle part and its periphery can be quickly and reliably removed.

  The abrasive can be provided on the inner wall of the dimple by application, spraying, etc., but the rubber member constituting the cleaning terminal itself is made to contain an abrasive as a whole, and the dimple is placed on the cleaning terminal. It is also possible to form. Since the abrasive polishes the needle part of the chuck part reliably, even if an oxide film or insulating film is formed on the needle part itself, the electrode will be removed when the oxide film is removed and chucked after cleaning. The electrical connection with the terminal can be ensured more reliably and quickly.

  The automatic cleaning unit of the present invention is more preferably characterized in that the cleaning terminal is made of a flexible member. Thus, when the chuck portion chucks the cleaning terminal, even if the cleaning terminal performs ultrasonic vibration, it is possible to avoid excessive vibration and unexpected pressing force being applied to the chuck portion.

  Further, the flexible member can flexibly cope with the clamping force due to chucking, and the ultrasonic vibration of the cleaning terminal is transmitted to every corner of the cleaning terminal without being excessively attenuated. This contributes to the cleaning of the entire chuck portion without unevenness.

  Further, the automatic cleaning unit of the present invention more preferably includes a suction nozzle for sucking dust removed from the chuck portion in the vicinity of the cleaning terminal. This prevents dust, etc., removed by ultrasonic cleaning from adhering to the chuck part, etc., or splashing into and out of the charge / discharge test equipment, and reliably collects and collects dust, etc. It becomes.

  There is a concern that dust that has been scattered to an unexpected location may be harmful to the human body, and it may not only enter into the gaps of various devices and accumulate, causing problems, but also reattaching to the chuck. There is a concern that the dust and the like may become an impediment to ensuring electrical connection with the electrode terminals of the secondary battery.

  For this reason, the automatic cleaning unit of this invention can be equipped with the vacuum part like what is called a mini vacuum cleaner which operate | moves with the battery for automatic cleaning units. The suction nozzle extended from the vacuum part to a position close to the cleaning terminal with a free nozzle such as bellows can be collected without scattering dust generated by cleaning the chuck part. Further, a vacuum unit such as a so-called mini vacuum cleaner may be provided with a HEPA filter. Thereby, it can be expected that the exhaust of the vacuum part is cleaned to the clean room level. Moreover, it is not necessary to separately clean the dust generated by the cleaning.

  In addition, the charge / discharge test apparatus of the present invention is a test line that sequentially performs charge / discharge tests on a plurality of secondary batteries to be charged / discharged, and has flowed on the test line instead of the secondary battery. Using any one of the automatic cleaning units, the chuck portion is automatically cleaned without stopping the test line.

  As a result, the automatic cleaning unit is appropriately flowed to the test line in the same manner as the secondary battery flowing to the test line without stopping the test line, thereby automatically cleaning the chuck portion without depending on the operator's work. A charge / discharge test apparatus can be realized.

  Conventionally, when cleaning the chuck part, all test lines are stopped, the power is turned off for safety, and the operator manually cleans each chuck part with a brush etc. It was. However, the structure of the chuck part is not only complicated, but depending on the arrangement of peripheral circuits and peripheral devices, it is forced to work in a very small work space, and the number of chuck parts per charge / discharge test device is extremely high. Since there are many, especially in a test line in which a large number of charge / discharge test apparatuses are arranged and the charge / discharge test is sequentially performed in a 24-hour system, the work requires man-hours, time, and cost.

  In addition, careful and precise cleaning work is required for each unit within the time limit for stopping the test line while moving the cart containing the cleaning tool set to the vicinity of each charge / discharge test device. The psychological burden on the operator was too great to ignore.

  In addition, the charge / discharge test apparatus of the present invention preferably includes a storage unit that stores a cleaning history of the chuck unit. Thereby, it becomes possible to perform automatic cleaning at an appropriate cleaning timing based on the past cleaning history.

  For example, the charge / discharge test apparatus may notify the operator that it is the timing of automatic cleaning after performing a predetermined number of times of chucking or a charge / discharge test for a predetermined time from the latest cleaning stored in the storage unit. Good.

  In addition, by using a charge / discharge test device with a cleaning history, in the unlikely event that a failure occurs, check the past cleaning history to determine the cause of the failure and countermeasures such as whether maintenance etc. were appropriate. It is possible to provide important information.

  Furthermore, when the next cleaning timing comes after performing a certain number of automatic cleanings, it is possible to notify the operator that it is time to replace the chuck portion itself.

  In addition, the charge / discharge test apparatus of the present invention is further preferably provided with a cleaning history notifying unit for notifying an operator of a cleaning history of the chuck portion. The notification to the operator may be printed out by voice, screen display, list display, or the like, and the charging / discharging device may include a speaker, a monitor, or a printer for notification.

  Moreover, the charge / discharge test apparatus of the present invention is more preferably characterized by comprising a control personal computer that determines cleaning conditions based on the cleaning history of the chuck portion stored in the storage portion. This makes it possible to perform automatic cleaning under more appropriate cleaning conditions.

  For example, for a chuck part that has already been automatically cleaned many times, it is possible that the chuck part has been polished to a certain degree and thus worn to some extent, so the intensity of ultrasonic vibration is reduced or the time is shortened. It is good also as cleaning conditions, such as.

  In addition, for example, for a relatively new chuck part that performs automatic cleaning for the first time, it is considered that the chuck part is not properly polished and worn, so the intensity of ultrasonic vibration is increased, the time is increased, etc. It is good also as the cleaning conditions.

  In addition, the charge / discharge test apparatus of the present invention further includes a wireless master device that transmits a cleaning condition determined by a control personal computer to an automatic cleaning unit. As a result, the automatic cleaning unit that has been transported to a predetermined test target position of the charge / discharge test apparatus by a conveyor or the like sets the cleaning condition that appropriately reflects the cleaning history of the chuck portion of the charge / discharge test apparatus. It becomes possible to instruct from the discharge test apparatus, and it becomes possible for the automatic cleaning unit to perform automatic cleaning that is individually adapted to the chuck portion of the charge / discharge test apparatus under specific cleaning conditions.

  The charge / discharge test system 1000 and the like exemplified in each of the above-described embodiments are not limited to the description in the embodiment, and the configuration and the like are appropriately within the scope of the technical idea described in the embodiment and the obvious range. The operation and the operation method can be changed. In addition, in the embodiment for convenience of explanation, even the matters individually described may be applied by appropriately combining the configurations, and the operations thereof may be appropriately combined and arranged.
