[0045] At present, from the development of market situation, the application of power battery is more and more extensive. The power battery is not only applied to the energy storage power supply system of water power, fire power, wind power and solar power station, but also widely applied to electric vehicles such as electric bicycles, electric motorcycles, electric vehicles and other electric vehicles, military equipment and aerospace and other fields. With the continuous expansion of the application field of power battery, the market demand is also increasing.

[0046] With the continuous expansion of market demand, the market requires higher and higher energy density of power battery, and more and more square batteries are put into the market. When the square power battery is used up on the whole vehicle, the capacity is still about 50%-70%. However, during the chemical reaction process of the battery, gas will be generated, so the cell will be swollen. If the secondary market wants to use these batteries again to realize the cascade utilization of power batteries, the swollen cells need to be reshaped and degassed.

[0047] At present, the related technology adopts six face normal pressure mode, which needs to deploy six servo cylinders on the six side surfaces of the cell, and realizes the pressure shaping through the movement of the six servo cylinders along the XYZ direction. The device of this shaping mode is bulky and occupies a large area. Moreover, the six servo cylinders directly pressurize the whole surface of the cell, which has the problems of poor shaping and poor degassing.

[0048] Therefore, the utility model provides a battery monomer shaping device with improved structure, which realizes the shaping of the battery monomer by inserting the first wedge block with an inclined surface into the accommodating cavity, can gradually pressurize and degas, and effectively improves the shaping effect.

[0049] The battery monomer in the utility model embodiment can be a secondary battery, which refers to a battery monomer that can be activated by charging after discharging to continue to use.

[0051] The battery monomer can be applied to various batteries. The battery mentioned here refers to a single physical module including one or more battery monomers to provide higher voltage and capacity. The battery monomer is the smallest unit of the battery. The battery monomer includes an electrode assembly capable of electrochemical reaction.

[0052] In some embodiments, the battery can include a box body and a battery monomer, and the battery monomer is accommodated in the box body.

[0053] In some embodiments, a plurality of battery cells can be connected in series or in parallel or in a mixed connection to form a battery module, and then a plurality of battery modules can be connected in series or in parallel or in a mixed connection to form a whole, which is accommodated in a box. In other embodiments, all battery cells are directly connected in series or in parallel or in a mixed connection, and then the whole formed by all battery cells is accommodated in a box. The box can be made of metal.

[0054] In some embodiments, the box can be part of the chassis structure of a vehicle. For example, part of the box can be at least part of the floor of the vehicle, or part of the box can be at least part of the cross beam and the longitudinal beam of the vehicle.

[0057] The battery can be used for power supply of the vehicle, for example, the battery can be used as the operating power source of the vehicle, for example, for the circuit system of the vehicle, such as for the working power demand of the vehicle during starting, navigation, and running. The battery can not only be used as the operating power source of the vehicle, but also be used as the driving power source of the vehicle, to replace or partially replace the fuel or natural gas to provide driving force for the vehicle.

[0058] The following will be described in combination with the accompanying drawings. Figures 1 to 9 Some embodiments of the battery cell shaping device provided by the present application are introduced.

[0059] Reference is made to the accompanying drawings Figures 1 to 5As shown, in the battery monomer shaping device embodiment provided by the utility model, the shaping device comprises a base 1, a first wedge block 2 and a first driving device 3, the base 1 is provided with a containing cavity 101 for containing the battery monomer 100, the first wedge block 2 comprises a first shaping surface 201 in contact with the first side surface 1001 of the battery monomer 100 and a first matching surface 202 matched with the first inner wall surface 102 of the containing cavity 101, the first matching surface 202 is inclined relative to the first shaping surface 201, and the first driving device 3 is configured to drive the first wedge block 2 to move along the first direction relative to the base 1 so that the first wedge block 2 is inserted into the containing cavity 101 and extrudes the first side surface 1001 of the battery monomer 100 in the process of insertion.

[0060] The battery monomer 100 is placed in the containing cavity 101, and the battery monomer 100 can be limited through the inner wall of the containing cavity 101. The containing cavity 101 has the containing and limiting effects on the battery monomer 100.

[0061] The first wedge block 2 comprises the first shaping surface 201 and the first matching surface 202, the first shaping surface 201 is used for being in contact with the first side surface 1001 of the battery monomer 100, and the first matching surface 202 is matched with the first inner wall surface 102 in the containing cavity 101.

[0062] When the first driving device 3 drives the first wedge block 2 to move along the first direction relative to the base 1, the first wedge block 2 gradually enters the containing cavity 101 under the driving force, in the process that the first wedge block 2 enters the containing cavity 101, the first shaping surface 201 on the first wedge block 2 is in contact with the first side surface 1001 of the battery monomer 100, and the first matching surface 202 is in contact with the first inner wall surface 102 in the containing cavity 101, since the first matching surface 202 is inclined relative to the first shaping surface 201, therefore, in the process that the first wedge block 2 enters the containing cavity 101, the first shaping surface 201 can extrude the first side surface 1001 of the battery monomer 100 constantly, the gas in the battery monomer 100 can be discharged gradually, the bulge on the battery monomer 100 can be eliminated gradually, and the shaping purpose is achieved.

[0063] In the utility model embodiment, since the first matching surface 202 is inclined relative to the first shaping surface 201, therefore, in the movement process of the first wedge block 2, the extrusion area and the extrusion force of the first wedge block 2 to the battery monomer 100 are changeable, unlike the six-face pressing mode in the related art that the whole face is extruded directly at the same time, therefore, the shaping device provided by the utility model embodiment can realize the gradual exhaust and gradual shaping, and effectively improve the shaping effect.

[0064] In some embodiments of the utility model, the first matching surface 202 matches the first inner wall surface 102 in the accommodating cavity 101, and the first matching surface 202 is inclined relative to the first shaping surface 201, therefore, the first inner wall surface 102 is also inclined relative to the first shaping surface 201.

[0065] In some embodiments, the first shaping surface 201 can be parallel to the first side surface 1001 of the battery monomer 100 before deformation or after shaping, and the first matching surface 202 and the first inner wall surface 102 in the accommodating cavity 101 are both inclined.

[0066] In the embodiments of the utility model, the inclination mode of the first matching surface 202 and the first inner wall surface 102 can be various, as long as the first wedge block 2 can gradually extrude the first side surface 1001 of the battery monomer 100 during the process of inserting into the accommodating cavity 101 and achieve the shaping purpose of the battery monomer 100.

[0067] In the embodiments of the utility model, the first direction is the movement direction of the first wedge block 2. Since the first matching surface 202 of the first wedge block 2 is inclined relative to the first shaping surface 201, the movement direction of the first wedge block 2 is different from the driving direction of the first driving device 3.

[0068] The driving direction of the first driving device 3 refers to the movement direction of the driving part of the first driving device 3.

[0069] In some embodiments of the utility model, the first driving device 3 can adopt an oil cylinder, an air cylinder or a motor.

[0070] In some embodiments of the utility model, the first driving device 3 can adopt a servo electric cylinder, the servo electric cylinder can set the stroke parameter, the repeated positioning accuracy of the servo electric cylinder reaches 0.01mm, the action accuracy can be effectively ensured, and the mispressing or out of the set range is prevented.

[0071] As shown in the figure, Figure 2 In some embodiments, the distance between the first matching surface 202 and the first shaping surface 201 decreases along the direction of inserting the first wedge block 2 into the accommodating cavity 101.

[0072] In the direction of the insertion of the first wedge 2 into the accommodating cavity 101, the thickness of the first wedge 2 tends to decrease. Therefore, in the early stage of the insertion of the first wedge 2 into the accommodating cavity 101, the extrusion force of the first wedge 2 on the battery monomer 100 is small due to the small distance between the first matching surface 202 and the first shaping surface 201; as the insertion depth increases, the distance between the first matching surface 202 and the first shaping surface 201 increases, and the extrusion force and the extrusion area of the first wedge 2 on the battery monomer 100 also increase, so that the gas inside the battery monomer 100 is gradually discharged; when the first wedge 2 is inserted to the preset position, the first wedge 2 can extrude the entire first side surface 1001 of the battery monomer 100, thereby achieving the shaping purpose of the first side surface 1001.

[0073] The distance between the first matching surface 202 and the first shaping surface 201 decreases in the direction of the insertion of the first wedge 2 into the accommodating cavity 101, which can include various cases, such as the distance between the first matching surface 202 and the first shaping surface 201 decreases in a stepped manner in the direction of the insertion of the first wedge 2 into the accommodating cavity 101, or the distance between the first matching surface 202 and the first shaping surface 201 gradually decreases in the direction of the insertion of the first wedge 2 into the accommodating cavity 101. These cases can all achieve the effects of gradual gas discharge and gradual shaping.

[0074] In some embodiments, the first inner wall surface 102 includes a first inclined section 1021 and a first non-inclined section 1022, the first inclined section 1021 is inclined relative to the first shaping surface 201, the first non-inclined section 1022 is parallel to the first shaping surface 201, and the first inclined section 1021 is located upstream of the first non-inclined section 1022 in the direction of the insertion of the first wedge 2 into the accommodating cavity 101.

[0075] By arranging the first non-inclined section 1022 downstream of the first inclined section 1021, the insertion resistance of the first wedge 2 can be reduced when the first wedge 2 is inserted to the bottom of the accommodating cavity 101, so as to avoid that the insertion of the first wedge 2 is hindered by the first inner wall surface 102, thereby affecting the normal insertion of the first wedge 2 and further affecting the shaping effect.

[0076] In some embodiments, the battery monomer shaping device further includes a first guiding device 4, the first guiding device 4 is configured to guide the movement of the first wedge 2 relative to the base 1.

[0077] By arranging the first guiding device 4, the movement path of the first wedge 2 can be guided and limited, so as to avoid that the movement of the first wedge 2 deviates, thereby affecting the shaping effect.

[0078] The structure of the first guiding device 4 can be various.

[0079] For example, the first guiding device 4 can include a first guiding surface 401, the first guiding surface 401 is arranged on the base 1, and the first guiding surface 401 is configured to guide the movement of the first wedge 2 relative to the base 1. Figure 3 For example, the first guiding device 4 can include a first guiding surface 401, the first guiding surface 401 is arranged on the base 1, and the first guiding surface 401 is configured to guide the movement of the first wedge 2 relative to the base 1. Figure 4As shown, in some embodiments, the first guide device 4 includes a first groove 401 disposed on the first mating surface 202 and a first boss 402 disposed on the first inner wall surface 102, the first boss 402 being able to be inserted into the first groove 401.

[0080] By setting the first groove 401 and the first boss 402, the first wedge 2 and the first inner wall surface 102 of the receiving cavity 101 can be relatively fixed in a direction other than the first direction through the cooperation of the first groove 401 and the first boss 402. This allows the first wedge 2 and the base 1 to only move relative to each other in the first direction, thereby restricting the movement path of the first wedge 2 and preventing the first wedge 2 from shifting and affecting the shaping effect.

[0081] The shape and number of the first groove 401 and the first boss 402 can be flexibly set as needed.

[0082] In some embodiments, the end of the first wedge 2 is provided with rounded corners to avoid scratching or damaging the surface of the battery cell 100 when the first wedge 2 is inserted into the receiving cavity 101.

[0083] In some embodiments, the battery cell shaping device further includes a second driving device 5, which is configured to drive the first wedge 2 to move relative to the base 1 in a second direction, so that the first wedge 2 leaves the receiving cavity 101 and releases the pressure on the battery cell 100. The second direction is opposite to the first direction.

[0084] By setting the second driving device 5, the first wedge 2 can be driven to move relative to the base 1 in a second direction opposite to the first direction, so that the first wedge 2 can be disengaged from the receiving cavity 101, so as to facilitate the removal of the shaped battery cell 100.

[0085] In some embodiments of this utility model, the second driving device 5 may be a hydraulic cylinder, a pneumatic cylinder, or a motor, etc.

[0086] In some embodiments of this utility model, the second driving device 5 can be a servo electric cylinder. The servo electric cylinder can be set with stroke parameters. The repeatability of the servo electric cylinder is 0.01mm, which can effectively ensure the accuracy of the action and prevent the first wedge 2 from falling to a position that is difficult to pick up.

[0087] like Figure 7 As shown, in some embodiments, the battery cell shaping device further includes a lifting member 6, which is drivenly connected to the second driving device 5. The bottom of the base 1 is provided with a through hole, and the second driving device 5 drives the lifting member 6 through the through hole to drive the first wedge 2 to move relative to the base 1.

[0088] By setting up the lifting member 6, it can pass through the through hole set on the base 1, thereby contacting the first wedge 2 and driving the first wedge 2 to leave the receiving cavity 101.

[0089] The structure of the lifting member 6 can be flexibly configured. The shape of the lifting member 6 can be the same as the shape of the through hole so that the lifting member 6 can pass through the through hole.

[0090] like Figure 3 As shown, in some embodiments, the battery cell shaping device further includes a second wedge 7. The second wedge 7 includes a second shaping surface 701 that contacts the second side surface 1002 of the battery cell 100 and a second mating surface 702 that mates with the second inner wall surface 103 of the receiving cavity 101. The second mating surface 702 is inclined relative to the second shaping surface 701, and the first side surface 1001 is adjacent to the second side surface 1002.

[0091] By setting the second wedge 7, the second side 1002 of the battery cell 100, which is adjacent to the first side 1001, can be gradually squeezed.

[0092] The second shaping surface 701 contacts the second side surface 1002 of the battery cell 100. The second shaping surface 701 can be parallel to the second side surface 1002 of the battery cell 100 before deformation or after shaping. The second mating surface 702 mates with the second inner wall surface 103 of the receiving cavity 101. The second mating surface 702 is inclined relative to the second shaping surface 701. Therefore, the second inner wall surface 103 is also inclined relative to the second shaping surface 701.

[0093] The movement of the second wedge 7 relative to the base 1 can be achieved by a driving device, which can be the first driving device 3 or other driving devices independent of the first driving device 3.

[0094] In some embodiments, the first drive device 3 is further configured to drive the second wedge 7 to move relative to the base 1 in a third direction, so that the second wedge 7 is inserted into the receiving cavity 101 and squeezes the second side 1002 of the battery cell 100 during insertion.

[0095] The third direction is the direction of movement of the second wedge 7. Since the second mating surface 702 of the second wedge 7 is inclined relative to the second shaping surface 701, the direction of movement of the second wedge 7 is different from the driving direction of the first driving device 3.

[0096] The first wedge 2 and the second wedge 7 are respectively disposed on different sides of the battery cell 100, so the first direction and the third direction are different.

[0097] By setting the first driving device 3 to drive the second wedge block 7, the first driving device 3 can be used to drive the first wedge block 2 and the second wedge block 7 at the same time, thereby reducing the number of driving devices, simplifying the overall structure of the shaping device, and reducing the floor area. It can also achieve synchronous movement of the first wedge block 2 and the second wedge block 7, and synchronous shaping of the first side surface 1001 and the second side surface 1002.

[0098] As shown in Figure 3 In some embodiments, the distance between the second matching surface 702 and the second shaping surface 701 decreases in the direction in which the second wedge block 7 is inserted into the accommodating cavity 101.

[0099] In the direction in which the second wedge block 7 is inserted into the accommodating cavity 101, the thickness of the second wedge block 7 shows a decreasing trend. Therefore, in the initial stage of the insertion of the second wedge block 7 into the accommodating cavity 101, the extrusion force of the second wedge block 7 on the battery monomer 100 is small due to the small distance between the second matching surface 702 and the second shaping surface 701. As the insertion depth increases, the distance between the second matching surface 702 and the second shaping surface 701 increases, and the extrusion force and the extrusion area of the second wedge block 7 on the battery monomer 100 also increase, thereby gradually discharging the gas inside the battery monomer 100. When the second wedge block 7 is inserted to the preset position, the second wedge block 7 can form extrusion on the entire second side surface 1002 of the battery monomer 100, thereby achieving the shaping purpose of the second side surface 1002.

[0100] In some embodiments, the distance between the second matching surface 702 and the second shaping surface 701 decreases in the direction in which the second wedge block 7 is inserted into the accommodating cavity 101. This can include various cases, such as the distance between the second matching surface 702 and the second shaping surface 701 decreasing in a stepped manner in the direction in which the second wedge block 7 is inserted into the accommodating cavity 101, or the distance between the second matching surface 702 and the second shaping surface 701 gradually decreasing in the direction in which the second wedge block 7 is inserted into the accommodating cavity 101. These cases can all achieve the effect of gradually discharging and gradually shaping.

[0101] In some embodiments, the second inner wall surface 103 includes a second inclined section 1031 and a second non-inclined section 1032. The second inclined section 1031 is inclined relative to the second shaping surface 701, and the second non-inclined section 1032 is parallel to the second shaping surface 701. In the direction in which the second wedge block 7 is inserted into the accommodating cavity 101, the second inclined section 1031 is located upstream of the second non-inclined section 1032.

[0102] By setting the second non-inclined section 1032 downstream of the second inclined section 1031, the insertion resistance of the second wedge block 7 can be reduced when the second wedge block 7 is inserted into the bottom of the accommodating cavity 101, thereby avoiding the insertion of the second wedge block 7 being hindered by the second inner wall surface 103, affecting the normal insertion of the second wedge block 7, and further affecting the shaping effect.

[0103] In some embodiments, the end of the second wedge 7 is provided with a rounded corner to avoid scratching or bruising the surface of the battery cell 100 when the second wedge 7 is inserted into the accommodation cavity 101.

[0104] In some embodiments, the length of the jacking piece 6 is sufficient to drive the second wedge 7 to move in the opposite direction of the third direction, so that the second wedge 7 can leave the accommodation cavity 101.

[0105] In some embodiments, the battery cell shaping device further comprises a second guiding device configured to guide the movement of the second wedge 7 relative to the base 1.

[0106] By providing the second guiding device, the movement path of the second wedge 7 can be guided and limited, avoiding the movement of the second wedge 7 from deviating and affecting the shaping effect.

[0107] In some embodiments, the second guiding device comprises a second groove provided on the second mating surface 702 and a second protrusion provided on the second inner wall surface 103, and the second protrusion can be inserted into the second groove.

[0108] As shown in Figure 1 and Figure 2 In some embodiments, the battery cell shaping device further comprises a partition plate 8 provided in the accommodation cavity 101 to divide the accommodation cavity 101 into a first cavity and a second cavity, and the first cavity and the second cavity are respectively used to accommodate the battery cell 100. The battery cell shaping device comprises two first wedges 2 and one second wedge 7, and the two first wedges 2 are respectively provided in the first cavity and the second cavity away from the partition plate 8 on one side, and the second wedge 7 simultaneously extrudes the battery cells 100 in the first cavity and the second cavity.

[0109] By providing the partition plate 8, the accommodation cavity 101 can be divided into two chambers, so that two battery cells 100 can be placed in one accommodation cavity 101. One of the two first wedges 2 extrudes one of the battery cells 100, and the other first wedge 2 extrudes the other battery cell 100. The second wedge 7 can simultaneously extrude the two battery cells 100, so that the two battery cells 100 share one second wedge 7.

[0110] In some embodiments, the base 1 is provided with two accommodation cavities 101, and four battery cells 100 can be placed in the two accommodation cavities 101.

[0111] As shown in Figure 5 In some embodiments, the battery cell shaping device further comprises a pressing plate 9, and the first driving device 3 is drivingly connected with the pressing plate 9. The first driving device 3 drives the pressing plate 9 to move relative to the base 1, and the pressing plate 9 simultaneously drives the first wedge 2 and the second wedge 7 to be inserted into the accommodation cavity 101.

[0112] By setting the pressing plate 9 and enabling the pressing plate 9 to simultaneously drive the first wedge block 2 and the second wedge block 7 to insert into the accommodating cavity 101, the first driving device 3 can be used to simultaneously drive the first wedge block 2 and the second wedge block 7 to move relative to the base 1, thereby saving the number of driving devices and realizing synchronous movement of the first wedge block 2 and the second wedge block 7.

[0113] As shown in Figure 6 some embodiments, the side of the pressing plate 9 close to the first wedge block 2 is provided with an avoiding groove 901.

[0114] By setting the avoiding groove 901 on the side of the pressing plate 9 close to the first wedge block 2, the pole or the explosion-proof valve and other components provided on the third side 1003 of the battery monomer 100 can be avoided, and the pressing plate 9 can be prevented from crushing the pole or the explosion-proof valve and other components.

[0115] The number and shape of the avoiding groove 901 can be set according to the number and shape of the pole or the explosion-proof valve and other components provided on the third side 1003.

[0116] As shown in Figure 8 and Figure 9 some embodiments, the battery monomer shaping device further comprises a rack 10 and a third driving device 11, the base 1 and the first driving device 3 are arranged on the rack 10, and the third driving device 11 is configured to drive the base 1 to move relative to the rack 10 along a fourth direction, so that the base 1 leaves the projection range of the first driving device 3 on the rack 10 along the driving direction of the first driving device 3, and the fourth direction is perpendicular to the driving direction of the first driving device 3.

[0117] By setting the third driving device 11, the base 1 can be driven to move relative to the rack 10 along the fourth direction, so that the base 1 leaves the projection range of the first driving device 3 on the rack 10 along the driving direction of the first driving device 3, thereby facilitating the putting in and taking out of the battery monomer 100, the first wedge block 2 and the second wedge block 7, avoiding the influence of the first driving device 3 on the putting in and taking out of the battery monomer 100, the first wedge block 2 and the second wedge block 7, and improving the safety of operation.

[0118] In some embodiments of the utility model, the third driving device 11 can adopt an oil cylinder, an air cylinder or a motor.

[0119] In some embodiments of the utility model, the third driving device 11 can adopt a servo cylinder, the servo cylinder can set the stroke parameter, the repeated positioning accuracy of the servo cylinder reaches 0.01mm, the action accuracy can be effectively guaranteed, and the base 1 can be prevented from rushing out of the set range.

[0120] In some embodiments, the battery cell shaping device includes two shaping units 12, each shaping unit 12 including a base 1, a first driving device 3 and a third driving device 11, the two shaping units 12 are arranged along a fifth direction, the fifth direction is perpendicular to the fourth direction and the driving direction of the first driving device 3.

[0121] By setting two shaping units 12, multiple battery cells 100 can be shaped simultaneously through the two shaping units 12, effectively improving the shaping efficiency.

[0122] Moreover, the two shaping units 12 are arranged along the fifth direction, so that the shaping processes of the two shaping units 12 do not interfere with each other. The shaping processes of the two shaping units 12 can be synchronized or asynchronous.

[0123] Based on the above-mentioned battery cell shaping device, this utility model also provides a battery processing equipment, which includes the above-mentioned battery cell shaping device.

[0124] The positive effects of the battery cell shaping device in the above embodiments are also applicable to battery processing equipment, and will not be described in detail here.

[0125] The following is in conjunction with the appendix Figures 1 to 9 The structure and shaping principle of one embodiment of the battery cell shaping device provided by this utility model will be introduced.

[0126] In this embodiment, the battery cell shaping device includes a base 1, a first wedge 2, a first driving device 3, a first guiding device 4, a second driving device 5, a lifting member 6, a second wedge 7, a separator 8, a pressure plate 9, a frame 10, a third driving device 11, and a shaping unit 12.

[0139] As shown, the first inner wall surface 102 is provided with a first boss 402. The first boss 402 can be inserted into the first groove 401 to guide the movement of the first wedge block 2. Figure 4 The second inner wall surface 103 is provided with a second boss. The second boss can be inserted into the second groove to guide the movement of the second wedge block 7.

[0140] As shown, the driving part of the first driving device 3 is connected with a pressing plate 9, which can press on the top surface of the first wedge block 2 and the second wedge block 7, so as to drive the first wedge block 2 and the second wedge block 7 to move synchronously through the first driving device 3 until the pressing plate 9 presses on the third side surface 1003 of the battery monomer 100.

The first guide column 14 is provided in the guide sleeve 13, and the guide sleeve 13 is used to guide the movement of the first guide column 14. The four first guide columns 14 are arranged in parallel with the driving part of the first driving device 3, and the extension direction of the first guide column 14 is parallel with the extension direction of the driving part of the first driving device 3 and the movement direction of the driving part. The two ends of the four first guide columns 14 are respectively connected with a frame plate and the first support plate 15, and the middle of the first guide column 14 is further connected with a connecting plate, so that the frame plate, the first support plate 15 and the connecting plate can realize the relative fixation of the four first guide columns 14. The first guide column 14 can lengthen the length of the driving part. The driving part of the first driving device 3 is connected with the first support plate 15, and the pressing plate 9 is installed at the bottom of the first support plate 15.

[0142] As shown, the first inner wall surface 102 is provided with a first boss 402. The first boss 402 can be inserted into the first groove 401 to guide the movement of the first wedge block 2.

[0143] As​Figure 6 As shown, the bottom surface of the pressure plate 9 is provided with multiple clearance grooves 901, which can avoid the poles and explosion-proof valves and other components provided on the third side 1003 of the battery cell 100.

[0144] like Figure 6 The diagram shows the drive assembly for two shaping units 12. Each shaping unit 12 includes a first drive device 3 and a pressure plate 9. The pressure plate 9 connected to each first drive device 3 can simultaneously drive four first wedges 2 and two second wedges 7 to move.

[0145] like Figure 7 As shown, the battery cell shaping device also includes a lifting plate 16, a second guide post 17, and a second support plate 18. Each lifting plate 16 is connected to four lifting members 6. The second support plate 18 is connected to the bottom of the lifting plate 16 via two second guide posts 17. The second guide posts 17 are also connected to U-shaped seats to achieve relative fixation of the four lifting members 6. The driving part of the second driving device 5 is connected to the lifting plate 16. Each second driving device 5 can drive the four lifting members 6 to move synchronously, thereby driving the four first wedges 2 and the two second wedges 7 to rise together until they leave the receiving cavity 101.

[0146] like Figure 8 and Figure 9 As shown, the battery cell shaping device also includes an upper cabinet door 19, a lower cabinet door 20, a fan 21, an indicator light 22, a crossbeam 23, a pressure sensor 24, a touch screen 25, a movable plate 26, an operation box 27, a support platform 28, a base frame 29, and a stamping tie rod 30.

[0147] The upper cabinet door 19 is used to close the first drive unit 3 and its adjacent components, and the lower cabinet door 20 is used to close the second drive unit 5 and its adjacent components.

[0148] Fan 21 can dissipate heat from electrical equipment and prevent the electrical equipment from overheating due to heat accumulation.

[0149] Indicator light 22 is a three-segment indicator light with red, yellow and green colors. Its main function is to serve as a visual observation object, directly reflecting the working status of the shaping device, so that operators can perform different operations according to different working statuses.

[0150] The crossbeam 23 is located inside the frame 10. The crossbeam 23 is the main load-bearing component of the first drive device 3. The guide sleeve 13 is mounted on the crossbeam 23, which is also the main load-bearing component for the internal forces of the device. The crossbeam consists of a square steel bar sandwiched between two steel plates, primarily to ensure that the movement direction of the first guide column 14 remains perpendicular. Each of the two steel plates on the crossbeam 23 has eight holes for mounting the guide sleeve 13. The middle of the steel plate connects to the first drive device 3. The lower steel plate and the stamped tie rod 30 both have flange faces, which are connected by bolts. The steel plates and the square steel bar are connected by welding.

[0151] The pressure sensor 24 is a pressure sensing device during pressing and shaping, which is installed at the end of the first driving device 3. When the first driving device 3 is working under pressure, the pressure of the first driving device 3 will be detected by the pressure sensor 24 and transmitted to the PLC for calculation.

[0152] The touch screen 25 is a human-computer interaction interface, which can select different battery cell models as processing objects on the touch screen 25, and can also perform position teaching and saving functions of the first driving device 3, the second driving device 5 and the third driving device 11. At the same time, the touch screen 25 can also display and set the pressure data of the two shaping units 12, and can also perform alarm query and reset. When the equipment is abnormal, the touch screen 25 can jog the first driving device 3, the second driving device 5 and the third driving device 11 to eliminate the equipment abnormality.

[0153] The movable plate 26 is a carrier of the shaping unit 12. The base 1 is fixed on the movable plate 26 by bolts, and the movable plate 26 is fixed on the linear guide rail by bolts. The movable plate 26 drives the movable part of the linear guide rail to move relative to the rack 10 by the third driving device 11, so as to guide and drive the movable plate 26 and the shaping unit 12 installed on the movable plate 26 to move relative to the rack 10. The movable plate 26 is provided with mounting holes suitable for various shaping units 12, so as to adapt to the shaping requirements of battery cells of different sizes. The linear guide rail can be used to transport the shaping unit 12 to and from the loading station (a position away from the projection range of the first driving device 3) and the processing station (located below the first driving device 3). Four linear guide rails can be arranged for each shaping unit 12 to ensure the strength of the overall equipment under heavy load.

[0154] The operation box 27 is a main operation interface for personnel, which is provided with a reset button, a start button, a lifting button, a lowering button and an emergency stop button. The start button, the lifting button and the lowering button are double-hand buttons to prevent safety risks caused by personnel misoperation.

[0155] The support table 28 is a main bearing and precision maintaining mechanism of the equipment, which is designed as a whole steel plate. The shaping unit 12 and the operation box 27 are installed on the support table 28.

[0156] The bottom frame 29 is arranged below the rack 10, and the second driving device 5 is arranged in the bottom frame 29. The overall frame composed of the rack 10 and the bottom frame 29 is a square steel frame structure, which mainly constitutes the appearance surface and frame of the equipment and provides support and shape maintenance for the internal mechanism.

[0157] The stamping pull rod 30 is an internal force bearing component of the device system. When the first driving device 3 moves downward, the corresponding force is transmitted downward. When the force is transmitted to the base 1, the base 1 and the cross beam 23 will not produce relative displacement due to the existence of the stamping pull rod 30. The internal force of the system is absorbed by the stamping pull rod 30, which plays a buffering role.

[0158] The rack 10 can also be provided with a safety protection device, such as a safety grating. Each shaping unit 12 is respectively provided with a corresponding safety grating, and the detection accuracy of the safety grating can be set. The safety grating is selected to be effective or ineffective according to the PLC program: after the shaping unit 12 enters the machining station, the grating is effective, at this time, if foreign matter intrudes into the grating protection area, the PLC action device stops urgently, and after resetting, the device allows action; when the shaping unit 12 is outside the machining station, the grating is invalid, at this time, if foreign matter intrudes, the PLC does not act.

[0159] The first driving device 3 provides power for the up-and-down movement of the pressing plate 9. The first driving device 3 can include a servo motor, a speed reducer, an absolute value encoder, a brake and other hardware. The first driving device 3 can set the stroke parameters in the touch screen 25. When shaping different sizes of battery monomers, different absolute position values can be set according to the actual height of the battery monomer, so as to ensure the shaping effect and not to over-press the battery monomer. A pressure sensor 24 is arranged at the end of the first driving device 3. The PLC reads the analog quantity of the pressure sensor 24 in real time and performs calculation. The data is sent to the touch screen 25 through the field bus network for display. In addition, different pressurization values can be set in the touch screen 25. When the actual pressurization pressure exceeds the set threshold, the device alarms and stops urgently.

[0160] The second driving device 5 provides power for the jacking of the first wedge block 2 and the second wedge block 7. After the first driving device 3 completes pressurization, it is difficult to take out the first wedge block 2 and the second wedge block 7 by manpower only due to the action of friction. Therefore, the second driving device 5 can reduce the difficulty of manual removal.

[0161] The shaping process of the battery monomer shaping device is as follows:

[0162] First, the inflated battery monomer 100 is loaded into the containing cavity 101 of the base 1, and the first wedge block 2 and the second wedge block 7 are pre-embedded;

[0163] Then, the device is started. Under the action of the third driving device 11, the movable plate 26 drives the shaping unit 12 to automatically move to the machining station (i.e. directly below the first driving device 3);

[0164] When the in-place switch triggers, the pressing plate 9 is driven by the first driving device 3 to move down along the first guide column 14, and starts to press after contacting the first wedge 2 and the second wedge 7, the first wedge 2 and the second wedge 7 slowly slide into the accommodating cavity 101, and the six faces of the bulging battery cell 100 are pressed and deformed due to the space limitation of the inner wall surface of the accommodating cavity 101 and the first wedge 2 and the second wedge 7, and when the first driving device 3 runs to the set position, the reshaping amount reaches the maximum, at this time, the reshaping of the bulging battery cell 100 is completed.

[0165] After the battery cell is reshaped, after the volume measurement and the re-blue film packaging process, the battery cell can be re-packed or reused.

[0166] During the reshaping process, the first wedge 2 and the second wedge 7 decompose the movement of the first driving device 3 in the vertical direction into horizontal and vertical movements. The movement of the first wedge 2 and the second wedge 7 in the horizontal direction will generate extrusion force on the bulging face of the battery cell 100. The inner wall of the accommodating cavity 101, the two first wedges 2 and the second wedge 7 together can extrude the four sides of the two battery cells 100 at one time, and when the first wedge 2 and the second wedge 7 completely enter the inside of the accommodating cavity 101, the pressing plate 9 is just pressed on the upper surface of the battery cell 100, so that the bulging battery cell 100 is limited in the XYZ three directions and deformed inward to achieve the reshaping effect. The included angle between the first reshaping surface 201 of the first wedge 2 and the first matching surface 202 is the complementary angle of the included angle between the first inner wall surface 102 and the horizontal plane, so as to ensure that the downward direction of the first wedge 2 is vertical. The included angle between the second reshaping surface 701 of the second wedge 7 and the second matching surface 702 is the complementary angle of the included angle between the second inner wall surface 103 and the horizontal plane, so as to ensure that the downward direction of the second wedge 7 is vertical.

[0167] After the battery cell 100 is reshaped, the third driving device 11 can be used to return the reshaping unit 12 to the feeding position (away from the lower side of the first driving device 3), and after the in-place detection is OK, the lifting button light on the operation box is on, indicating that the personnel can operate the second driving device 5 to lift the first wedge 2 and the second wedge 7. After pressing the lifting button, the PLC receives the trigger signal and sends the action signal to the second driving device 5, and the second driving device 5 starts to act, and the lifting plate 16 is driven by the second driving device 5 to move upward, synchronously driving the lifting piece 6 to move upward, and the lifting piece 6 directly contacts the first wedge 2 and the second wedge 7, and the first wedge 2 and the second wedge 7 are lifted. When the action of the second driving device 5 is in place, it is automatically stopped. After the battery cell 100, the first wedge 2 and the second wedge 7 are manually taken out, the second driving device 5 drives the above-mentioned mechanism to move downward as a whole to return to the standby position.

[0168] The above description of the various embodiments tends to emphasize differences between the various embodiments, and the same or similar elements can be referred to each other for the sake of brevity, which will not be repeated here.

[0169] Although the present application has been described with reference to preferred embodiments, various modifications can be made to the application without departing from the scope thereof. In particular, the technical features mentioned in the various embodiments can be combined in any manner as long as there is no structural conflict.
