Referring to fig. 1 and 2, the present invention provides a battery formation and grading cabinet 10 for forming batteries. The battery formation and grading cabinet 10 includes a cabinet body 100 and a formation assembly 200.

The cabinet 100 has a hollow structure and has a receiving cavity 110. A plurality of formation stations are arranged in the accommodating cavity 110. Specifically, the cabinet 100 serves as a receptacle and provides a relatively closed formation space for formation of the battery 40, so as to prevent the battery 40 from being affected by the external environment during formation.

Specifically, the cabinet 100 has a cubic shape, which facilitates the cabinet 100 to be placed on a mounting surface such as the ground. The formation stations are arranged at intervals along the height direction of the cabinet 100. The side wall of the cabinet 100 is further provided with a plurality of mounting openings, and each mounting opening corresponds to a formation station. The installation opening is arranged to facilitate placement of the formed component 200 on a forming station from the installation opening. In addition, each installation opening is also provided with a plurality of transparent door bodies. The door bodies are in one-to-one correspondence with the mounting openings. Each door body covers a plurality of mounting openings corresponding to the door body, and is used for closing the mounting openings. Moreover, the door body is transparent, so that an operator can conveniently monitor the formation process of the battery 40 in the accommodating cavity 110 through the door body.

The formation assembly 200 is received in the receiving cavity 110 to form the battery 40. Specifically, the number of the formation assemblies 200 and the number of the formation stations may correspond one to one. By arranging one formation assembly 200 at each formation station, a plurality of batteries 40 can be formed at the same time, so that the working efficiency of the battery 40 formation and grading cabinet 10 is improved.

In the present embodiment, the battery 40 formation and content storage container 10 further includes a thermostat 300. The thermostatic regulating member 300 is disposed in the cabinet 100 and is used for regulating the temperature in the accommodating cavity 110 so as to maintain the temperature within a preset range.

When the battery 40 is formed, the quality of the formation effect is also closely related to the operating temperature. When the formation temperature is too high, the battery 40 is likely to generate heat during formation, and the battery 40 is damaged. The formation temperature is too low, which easily causes the deposition of metal simple substances in the battery 40, and reduces the service life of the battery 40. By providing the thermostatic element 300, the temperature in the accommodating chamber 110 can be maintained within a predetermined range, so as to meet the temperature requirement of the battery 40. Specifically, the preset range refers to a temperature range in which the battery 40 can be normalized.

With, the thermostat 300 may be an air conditioner.

The assembly 200 includes a platen 201, a support 202, a stop 203, and a stop 204. Formed component 200 has an initial state and a formed state.

The platen 201 includes a first platen 2011, a second platen 2012, and a third platen 2013. The first pressing plate 2011, the second pressing plate 2012 and the third pressing plate 2013 are arranged in parallel and at intervals in sequence. The first press plate 2011 is used to carry either the positive probe assembly 20 or the negative probe assembly 30. The second platen 2012 carries the battery 40. The third platen 2013 is used to carry the other of the positive probe assembly 20 or the negative probe assembly 30. Specifically, in this embodiment, the first platen 2011 carries the positive probe assembly 20 and the third platen 2013 carries the negative probe assembly 30.

The positive probe assembly 20, the battery 40, and the negative probe assembly 30 are all plural. The plurality of positive probe assemblies 20 are aligned with the positive post locations of the plurality of cells 40 and the plurality of negative probe assemblies 30 are aligned with the negative post locations of the plurality of cells 40. Providing multiple positive probe assemblies 20, cells 40, and negative probe assemblies 30 simultaneously on formation assembly 200 can improve the efficiency of formation of cells 40.

Specifically, to facilitate the loading and unloading of the plurality of batteries 40, the plurality of batteries 40 may be placed in a tray 50 of batteries 40. The battery 40 tray 50 is carried on the second pressing plate 2012 and is used for fixing the plurality of batteries 40.

To facilitate the positive probe assembly 20, the negative probe assembly 30, and the battery 40 to slide under the influence of gravity during installation on the platen 201, the first platen 2011 or the third platen 2013 is generally placed on a horizontal plane to ensure the horizontal placement of the first platen 2011, the second platen 2012, and the third platen 2013. Specifically, in this embodiment, the third pressing plate 2013 is disposed on the mounting surface, the first pressing plate 2011 is located at the top end of the pressing plate 201, and the second pressing plate 2012 is located between the first pressing plate 2011 and the second pressing plate 2012. In other embodiments, the first pressure plate 2011 may be placed on the mounting surface, and the third pressure plate 2013 may be positioned at the top end of the pressure plate 201.

The first pressure plate 2011 and the second pressure plate 2012 are operable to be slidable in a direction perpendicular to the first pressure plate 2011 to switch the formation assembly 200 between the initial state and the formation state. Specifically, the first pressure plate 2011 and the second pressure plate 2012 slide in a direction perpendicular to the first pressure plate 2011, including the first pressure plate 2011 and the second pressure plate 2012 slide in a direction toward and away from the third pressure plate 2013.

In this embodiment, the platen 201 also includes a top platen 2014. The top pressing plate 2014 is stacked on the side of the first pressing plate 2011, which faces away from the second pressing plate 2012, and is parallel to the first pressing plate 2011 and spaced from the first pressing plate 2011 to form a mounting portion 2015. By arranging the top laminate 2014, a complete whole can be formed between the top laminate 2014 and the first, second and

third press plates

2011, 2012 and 2013 through supporting, so that the integrity of the formed component 200 is stronger.

Generally, since the cabinet 100 is cube-shaped, the first pressing plate 2011, the second pressing plate 2012, the third pressing plate 2013 and the top pressing plate 2014 are rectangular plates and have the same size in the length and width directions, so that the pressing plate 201 has a square structure, and an operator can conveniently and fully utilize the space in the accommodating cavity 110 to arrange the pressing plate 201.

The support 202 is plural. A plurality of supports 202 are provided along the circumferential direction of the platen 201. The support 202 is used to support the first platen 2011, the second platen 2012 and the third platen 2013 to maintain the structural stability of the platen 201.

Specifically, the extending direction of the plurality of supports 202 is the same as the sliding direction of the first and

second platens

2011, 2012.

In the present embodiment, the plurality of supporting members 202 are disposed on the third pressing plate 2013 and penetrate the first pressing plate 2011 and the second pressing plate 2012. The top platen 2014 is supported on the end mounted to the support 202 remote from the third platen 2013.

In other embodiments, the plurality of supporting members 202 may also be disposed on the first pressing plate 2011 and penetrate through the first pressing plate 2011, the second pressing plate 2012 and the third pressing plate 2013.

The third platen 2013 is a rectangular plate having four corners, one support 202 disposed at each corner. The first pressure plate 2011 and the second pressure plate 2012 have through holes at positions corresponding to the plurality of supporting members 202. The supporting members 202 are cylindrical, and each supporting member 202 is inserted into a through hole corresponding to the supporting member 202 on the first pressing plate 2011 and the second pressing plate 2012, and is in clearance fit with the through hole.

In the embodiment, the support 202 can also guide the sliding of the first pressure plate 2011 and the second pressure plate 2012, so that the sliding of the first pressure plate 2011 and the second pressure plate 2012 is more stable, and further, each part of the first pressure plate 2011 and the second pressure plate 2012 can basically keep consistent in movement in the sliding process, so as to maintain a better parallelism between the first pressure plate 2011, the second pressure plate 2012 and the third pressure plate 2013.

In the present embodiment, the battery 40 chemical composition cabinet 10 further includes a plurality of first linear bearings 207 mounted on the first pressing plate 2011 and a plurality of second linear bearings 208 mounted on the second pressing plate 2012. The first linear bearings 207 and the second linear bearings 208 are respectively sleeved on the supports 202 and correspond to the supports 202 one by one.

Specifically, the plurality of through holes on the first pressure plate 2011 correspond to the plurality of first linear bearings 207 one by one, and each first linear bearing 207 is clamped in the through hole on the first pressure plate 2011 corresponding to the first linear bearing. The plurality of through holes of the second pressing plate 2012 are in one-to-one correspondence with the plurality of second linear bearings 208, and each second linear bearing 208 is clamped in the corresponding through hole of the second pressing plate 2012.

By providing a plurality of first linear bearings 207 and a plurality of second linear bearings 208, the first pressure plate 2011 and the second pressure plate 2012 slide more smoothly. Accordingly, the movement of the respective portions of the first and

second platens

2011, 2012 can be substantially consistent during the sliding movement to maintain a better parallelism between the first and

second platens

2011, 2012 and the third platen 2013.

The number of the stop members 203 is plural. The plurality of stopper members 203 are arranged along the circumferential direction of the second platen 2012. Each stopper 203 extends in a direction toward the first pressure plate 2011. In the present embodiment, the extending direction of the stop member 203 is the same as the sliding direction of the first pressure plate 2011 and the second pressure plate 2012. The stop member 203 may be rod-like, cylindrical, or other shape. The stop member 203 and the second pressing plate 2012 can be integrally formed or can be separately formed.

Specifically, when the formation assembly 200 is in the initial state, the first pressure plate 2011 and the plurality of stop members 203 are arranged at intervals. Meanwhile, the positive electrode probe assembly 20 on the first pressure plate 2011 is spaced from the positive electrode column of the battery 40, so as to form an open circuit between the positive electrode probe assembly 20 and the battery 40. Further, the positive electrode probe assembly 20 is prevented from being electrified and conducted with the battery 40 due to sudden power supply, and further, the positive electrode probe assembly 20 and the battery 40 are prevented from being exploded due to short circuit caused by poor contact of the positive electrode posts. When the formation assembly 200 is in the formation state, the first pressing plate 2011 slides, so that the first pressing plate 2011 abuts against the plurality of stop pieces 203, and at this time, the positive electrode probe assembly 20 on the first pressing plate 2011 is also in contact with the positive electrode column of the battery 40 on the second pressing plate 2012.

By arranging the plurality of stop members 203 along the circumferential direction of the second pressure plate 2012, the first pressure plate 2011 can make the first pressure plate 2011 and the second pressure plate 2012 have better parallelism when abutting against the plurality of stop members 203. Furthermore, the first pressing plate 2011 can uniformly apply pressure to the second pressing plate 2012, and the plurality of positive electrode probe assemblies 20 on the first pressing plate 2011 can uniformly apply pressure to the positive posts of the plurality of batteries 40 on the second pressing plate 2012, so that the pressure between each positive electrode probe assembly 20 and the positive post of each battery 40 is substantially maintained to be equal, and the reliability of the contact between the positive electrode probe assemblies 20 and the positive posts of the batteries 40 can be effectively improved. In the process of switching the formation assembly 200 from the initial state to the formation state, first, the positive electrode probe assembly 20 is spaced from the positive electrode column of the battery 40. As the first platen 2011 slides and comes closer to the second platen 2012, the positive probe assembly 20 first makes contact with the positive post of the battery 40. Further, the first pressure plate 2011 abuts against the plurality of stoppers 203 as the first pressure plate 2011 further slides. When the first pressure plate 2011 abuts against the stopper 203, the positive electrode probe assembly 20 is in a state of close contact with the positive post of the battery 40.

The blocking member 204 is plural. A plurality of the dam members 204 are arranged along the circumferential direction of the third platen 2013. Each stopper 204 extends in a direction toward the first pressure plate 2011. Specifically, the extending direction of the stopper 203 is the same as the sliding direction of the first pressure plate 2011 and the second pressure plate 2012. The stop member 203 may be rod-like, cylindrical, or other shape. The blocking member 204 and the third pressing plate 2013 may be integrally formed or may be separately formed.

Specifically, when the formation assembly 200 is in the initial state, the second pressing plate 2012 is spaced apart from the plurality of blocking members 204. Meanwhile, the negative pole of the battery 40 and the negative pole probe assembly 30 are spaced on the second pressing plate 2012, so as to form an open circuit between the negative pole probe assembly 30 and the negative pole of the battery 40. Further, it is possible to prevent the electrical conduction between the negative electrode column of the battery 40 and the negative electrode probe assembly 30 and the battery 40 due to a sudden power supply, and further prevent the explosion due to a short circuit caused by poor contact between the negative electrode probe assembly 30 and the negative electrode column of the battery 40. When the platen 201 is in the formation state, the second platen 2012 slides, so that the second platen 2012 gradually approaches the third platen 2013 and abuts against the plurality of stoppers 204. At this time, the negative posts of the cells 40 on the second platen 2012 also contact the negative probe assembly 30 on the third platen 2013. During the sliding of the second pressing plate 2012, the first pressing plate 2011 needs to continue to slide to ensure that the positive probe assembly 20 on the first pressing plate 2011 can contact the positive post of the battery 40.

By arranging the plurality of the position stoppers 204 along the circumferential direction of the third pressing plate 2013, the second pressing plate 2012 can be in better parallelism with the third pressing plate 2013 when abutting against the plurality of the position stoppers 204. Further, the first pressing plate 2011, the second pressing plate 2012 and the third pressing plate 2013 have higher parallelism in combination with the stop member 203. Furthermore, the negative posts of the plurality of cells 40 on the second pressing plate 2012 can uniformly apply pressure to the plurality of negative probe assemblies 30 on the third pressing plate 2013, so that the pressure between each negative probe assembly 30 and the negative post of each cell 40 is substantially maintained to be equal, and the reliability of the contact between the negative probe assembly 30 and the negative posts of the cells 40 can be effectively improved.

And according to the probe assembly and the battery 40 pole contact are more reliable, the contact resistance between the probe assembly and the battery 40 pole will be smaller, and the arrangement of the stop member 203 and the stop member 204 can effectively reduce the contact resistance between the positive pole of the positive probe assembly 20 and the battery 40 and between the negative pole of the negative probe assembly 30 and the battery 40. Therefore, when the power is applied to the positive probe assembly 20 and the negative probe assembly 30, heat generation of the battery 40 may be reduced to prevent the battery 40 from being damaged, thereby having a low wear rate of the battery 40.

It should be noted that, during the process of switching the formation assembly 200 from the initial state to the formation state, firstly, the negative pole of the battery 40 and the negative probe assembly 30 are spaced apart from each other. As the second platen 2012 slides, the spacing between the second platen 2012 and the third platen 2013 gradually decreases, and the negative pole of the battery 40 first contacts the negative probe assembly 30. Further, the second presser plate 2012 abuts against the plurality of stoppers 204 as the second presser plate 2012 slides further. When the second presser plate 2012 abuts the plurality of stoppers 204, the negative pole column of the battery 40 is in close contact with the negative probe assembly 30.

Specifically, the sliding of the first pressure plate 2011 may be operated by a human or a driving member. Specifically, in the present embodiment, the formation assembly 200 further includes a driving member 205, and the driving member 205 is used for driving the first pressing plate 2011 to slide.

By providing the driving member 205, the trouble of manual operation can be avoided, and the automation of the battery 40 into the container 10 can be easily realized.

Specifically, there may be one driving member 205 or a plurality of driving members 205, and preferably there are two driving members 205. The two driving members 205 can drive the first pressure plate 2011 to slide from two opposite sides of the first pressure plate 2011, so that the sliding of the first pressure plate 2011 is more stable.

Specifically, the driving member 205 may be a telescopic rod, a linkage mechanism, a telescopic cylinder or other forms of driving member 205, and in this embodiment, the driving member 205 is a telescopic cylinder. The telescopic shaft of the telescopic cylinder extends in a direction perpendicular to the first pressure plate 2011 and is in transmission connection with the first pressure plate 2011.

Specifically, the telescopic cylinder is arranged on the surface of the third pressing plate 2013 facing the second pressing plate 2012, and the tail end of the telescopic shaft is in transmission connection with the first pressing plate 2011. Thus. The telescopic cylinder is installed in the space of the pressing plate 201, so that the space formed by the telescopic cylinder and the pressing plate 201 can be overlapped, and the size of the assembly 200 is convenient to reduce.

Since the first pressure plate 2011, the second pressure plate 2012 and the third pressure plate 2013 are spaced from each other, the telescopic shaft can also provide a supporting force for the first pressure plate 2011 in the initial state, so as to prevent the first pressure plate 2011 from sliding in the direction toward the third pressure plate 2013. When the formation state is reached, the telescopic shaft contracts, and the first pressing plate 2011 can be pulled to slide along the direction towards the third pressing plate 2013, so that the first pressing plate 2011 contacts and presses the stop piece 203. At this time, the positive electrode probe assembly 20 on the first pressing plate 2011 can also contact and press the positive electrode column of the battery 40 on the second pressing plate 2012, and has better contact reliability.

Then, the telescopic cylinder continues to drive the first pressing plate 2011 to slide along the direction toward the third pressing plate 2013, and under the pressure action of the first pressing plate 2011, the second pressing plate 2012 is driven to slide along the direction toward the third pressing plate 2013, so that the second pressing plate 2012 can contact with the plurality of blocking members 204 on the third pressing plate 2013. It should be noted that, when the driving member 205 drives the first pressing plate 2011 to drive the second pressing plate 2012 to move toward the third pressing plate 2013, the first pressing plate 2011 always keeps abutting against the stop member 203, and the positive probe assembly 20 on the first pressing plate 2011 can be in close contact with the positive post of the battery 40 on the second pressing plate 2012.

After formation, the formation assembly 200 needs to be switched to an initial state from a formation state, the telescopic shaft extends in a direction perpendicular to the first pressing plate 2011, and the first pressing plate 2011 slides in a direction back to the third pressing plate 2013 under the driving of the telescopic shaft, so that the first pressing plate 2011 can reversely slide and is separated from the stop piece 203. Further, the positive electrode probe assembly 20 is also separated from the positive electrode column of the battery 40. The pressure exerted on the second platen 2012 by the first platen 2011 disappears.

In the process, the second pressing plate 2012 can be slid in a direction away from the third pressing plate 2013 by manual operation, or can be slid in a direction by arranging the driving member 205, the resetting member 206, and the like, so that the second pressing plate 2012 can be slid to the position where the initial state is located. In the present embodiment, the formation assembly 200 further includes a plurality of reset members 206 circumferentially disposed along the third platen 2013. Two opposite ends of each reset element 206 are respectively connected to the second pressure plate 2012 and the third pressure plate 2013, and the reset element 206 provides an elastic force directed to the first pressure plate 2011 for the second pressure plate 2012.

The spring force provided by the reset member 206 causes the second platen 2012 to have a tendency to slide away from the third platen 2013. When the first pressure plate 2011 slides in a direction away from the third pressure plate 2013, the pressure exerted by the first pressure plate 2011 on the second pressure plate 2012 gradually decreases until it disappears. In the process of gradually decreasing the pressure, when the elastic force is greater than the pressure applied by the first pressure plate 2011 on the second pressure plate 2012 and the gravity on the second pressure plate 2012, the elastic force can drive the second pressure plate 2012 to slide in the direction away from the third pressure plate 2013, so that the second pressure plate 2012 returns to the position of the initial state.

Specifically, in the initial state, the reset element 206 is still in a compressed state. The elastic force of the restoring member 206 is equal to the sum of the gravity of the second presser plate 2012, the tray 50 and the battery 40. It should be noted that, in the initial state, the length of the compressed reset element 206 is greater than the length of the blocking element 204, so that the reset element 206 can support the second pressing plate 2012 in the initial state and ensure that the negative pole of the battery 40 on the second pressing plate 2012 is not in contact with the negative probe assembly 30. When the initial state is switched to the formation state, the first pressing plate 2011 drives the second pressing plate 2012 to slide in a direction toward the third pressing plate 2013, and the resetting member 206 is further compressed until the second pressing plate 2012 contacts with the plurality of blocking members 204. At this time, the reset piece 206 has the maximum compression amount, and the compressed length of the reset piece 206 is equal to the length of the stop piece 203. In other embodiments, a convex column abutting against the reset piece 206 may be formed on a surface of the second platen 2012 facing the third platen 2013. When the second pressing plate 2012 contacts the stopper 204, the length of the resetting element 206 at the maximum compression amount is less than the length of the stopper 203 due to the convex column.

By arranging the plurality of resetting pieces 206 arranged along the circumferential direction of the third pressing plate 2013 at intervals, in the initial state and the formation state, the plurality of resetting pieces 206 can stably support the second pressing plate 2012 along the circumferential direction of the third pressing plate 2013 so as to keep a better parallelism between the second pressing plate 2012 and the third pressing plate 2013, and further, the negative pole of the battery 40 on the second pressing plate 2012 can be in close contact with the negative probe assembly 30 on the third pressing plate 2013.

Specifically, the reset element 206 may be disposed in a staggered manner with the position-blocking element 204, or may be sleeved on the position-blocking element 204. In the present embodiment, the plurality of resetting members 206 correspond to the plurality of position-blocking members 204 one by one, the resetting members 206 are wrap springs, and each resetting member 206 is wrapped on the position-blocking member 204 corresponding thereto.

On the one hand, the stop member 203 has a supporting and guiding function for the reset member 206. The reset piece 206 is sleeved on the reset piece 203, the reset piece 203 can support the reset piece 206, and the reset piece 206 can be guided in the further compression process of the reset piece 206 so as to prevent the reset piece 206 from shaking. On the other hand, the reset element 206 is sleeved on the stop element 203, so that the volumes of the reset element 206 and the stop element 203 are overlapped, and the occupied space of the reset element 206 and the stop element 203 can be reduced. Therefore, between the second platen 2012 and the third platen 2013, the reset member 206 hardly occupies the space between the adjacent blocking members 204, so that the space between the adjacent blocking members 204 is large. Further, the operator has a large observation range to observe the contact between the negative post of the battery 40 and the negative probe assembly 30 to ensure the normal progress of the formation.

In this embodiment, the battery 40 formation and grading cabinet 10 further includes a plurality of limiting members 209 disposed on the second pressing plate 2012, and a limiting portion 2091 is defined between the plurality of limiting members 209.

Generally, the shape and size of the limiting portion 2091 matches the shape and size of the tray 50. When the tray 50 is accommodated in the limiting portion 2091, the tray 50 can be clamped in the limiting portion 2091.

The tray 50 is clamped to the limiting portion 2091, and the position of the tray 50 can be limited, so as to prevent the positive probe assembly 20 and the negative probe assembly 30 from being unable to align with the positive post of the battery 40 and the negative post of the battery 40 respectively due to movement of the tray 50 in the formation process, and further prevent the battery 40 from being damaged due to heat generation caused by large contact resistance between the positive probe assembly 20 and the negative probe assembly 30 and the battery 40.

Specifically, the limiting element 209 may be a frame, a plate, or another structure, in this embodiment, the limiting element 209 is an inverted T-shaped structure, and the limiting elements 209 are multiple and are disposed at intervals along the surface of the second pressing plate 2012 facing the first pressing plate 2011.

By providing a plurality of spacing locating members 209, the use of material can be reduced, thereby facilitating a reduction in the production cost of the resulting assembly 200.

The limiting member 209 has an inverted T-shaped structure, and specifically, the limiting member 209 includes a base portion 2092 and a protruding portion 2093 protruding from the base portion 2092. The base portion 2092 and the protrusion 2093 are both elongated. The base portion 2092 is parallel to the first pressure plate 2011 and the protrusion 2093 is perpendicular to the base portion 2092 and extends in a direction perpendicular to the first pressure plate 2011. The length of the protrusion 2093 is equal to or less than the length of the stop 203. If the length of the protrusion 2093 is equal to the length of the stop member 203, the protrusion 2093 and the stop member 203 can support the second press plate 2012 together during the contact between the first press plate 2011 and the stop member 203, so that the second press plate 2012 is supported more stably and can maintain a better horizontal degree. If the length of the protrusion 2093 is smaller than the length of the stop member 203, the second presser plate 2012 is not in contact with the protrusion 2093 when the second presser plate 2012 is in contact with the stop member 203. However, if the supporting function of the position-stopping member 203 fails, the second pressing plate 2012 moves downward further, and the protrusion 2093 can support the second pressing plate 2012 again, so as to prevent the first pressing plate 2011 from sliding down too far, which causes the pressure between the positive electrode probe assembly 20 and the positive pole of the battery 40 to be too large, thereby causing the structure of the whole integrated assembly 200 to fail.

In this embodiment, the battery 40 chemical-volumetric cabinet 10 further includes a position sensor (not visible) and a controller. The position sensor is electrically connected with the controller. The position sensor is used for detecting whether the limiting part 2091 is idle or occupied, and the controller is used for sending a warning signal when the limiting part 2091 is idle.

Specifically, the position sensor is disposed on the second pressing plate 2012 and is configured to sense that the limiting portion 2091 is occupied or occupied, and feed back the space or occupied to the controller. Specifically, the empty state indicates that the stopper 2091 is not mounted with the tray 50. The occupancy indication stopper 2091 holds the tray 50. If the feedback signal of the limiting part 2091 received by the controller is idle, the controller sends out a warning signal to remind an operator to put the tray 50 carrying the battery 40 into the limiting part 2091, and the battery 40 is formed. Specifically, a warning light capable of emitting striking light can be arranged on the cabinet body 100, and the warning signal emitted by the controller can control the warning light to be turned on so as to remind the operator to install the tray 50 at the limiting portion 2091.

In this embodiment, the battery 40 chemical component container 10 further includes a smoke alarm 211 disposed in the chemical component 200. The smoke alarm 211 is retained in the mounting portion 2015.

When the battery 40 is formed, if the contact is poor in the process of the positive probe assembly 20 and the negative probe assembly 30 contacting the battery 40, the battery 40 may generate heat seriously, and the battery 40 may explode and generate smoke. However, the formation assembly 200 is enclosed in the cabinet 100. Therefore, the operator cannot sense the smoke in time, which results in serious safety accidents. And through set up smoke alarm 211 in installation department 2015, when battery 40 excessively generates heat and explodes, smoke alarm 211 perception smog that can be timely, and then send alarm signal, for example whistle, warning light scintillation to timely warning operation personnel handles the explosion accident, prevents that the accident from further worsening. Or the operator is reminded to timely get away from the operation place so as to avoid casualties. And through holding smoke alarm 211 in installation department 2015, can realize smoke alarm 211's simple installation, be convenient for improve smoke alarm 211's installation effectiveness.

The battery 40 is formed into the container 10, the plurality of positive electrode probe assemblies 20 are aligned with the positive electrode posts of the plurality of batteries 40 one by one, and the plurality of negative electrode probe assemblies 30 are aligned with the negative electrode posts of the plurality of batteries 40 one by one. When the formation assembly 200 is switched from the initial state to the formation state, the first pressure plate 2011 slides so that the first pressure plate 2011 abuts against the stopper 203. Further, the plurality of positive electrode probe assemblies 20 are brought into contact with the positive electrode posts of the plurality of batteries 40 and apply pressure to the positive electrode posts of the plurality of batteries 40. Further, the second presser plate 2012 slides so that the negative posts of the plurality of cells 40 contact the plurality of negative probe assemblies 30 and apply pressure to the plurality of negative probe assemblies 30. At the same time, the first pressure plate 2011 also slides to keep the positive probe assembly 20 in contact with the positive post of the battery 40 at all times. Because the plurality of stop members 203 are arranged along the circumferential direction of the second pressing plate 2012 and the plurality of stop members 204 are arranged along the circumferential direction of the third pressing plate 2013, the first pressing plate 2011, the second pressing plate 2012 and the third pressing plate 2013 can always keep a parallel state, so that the positive poles of the plurality of positive probe assemblies 20 and the plurality of batteries 40 and the negative poles of the plurality of negative probe assemblies 30 and the plurality of batteries 40 are uniformly pressed, the contact is reliable, and the loss rate of the batteries 40 is low.
