Description

Technical Field

[0001] This invention relates to the field of battery manufacturing, and more particularly, to a module support component, a module housing device, and a method. Background Technology

[0002] Module insertion is a crucial step in battery production. Existing insertion equipment uses a module carrier assembly directly connected to the insertion device via a slide rail. The battery module is then fed into the battery casing via the slide rail. The battery module on the carrier assembly and the battery casing on the insertion device are aligned at a fixed height, making it impossible to ensure that the center points of their mating surfaces are on the same straight line. This causes instability in the insertion process and uneven stress, which can easily damage the product, affecting yield and quality. This issue urgently needs improvement. Summary of the Invention

[0003] In view of this, the present invention provides a module support component, a module insertion device and method. During the insertion operation, the battery casing, battery module and pressure plate are on the same straight line, which can realize rapid alignment and insertion. Moreover, during the insertion and assembly process, the pressure on the battery casing and battery module is on the same straight line, which can effectively ensure the stable and reliable assembly of the product. Furthermore, the product is subjected to uniform stress, making it less prone to deformation and other defects, resulting in better product quality.

[0004] The objective of this invention is achieved through the following technical solution: A module support assembly includes a support base, a primary lifting unit connected to the support base, a slide rail assembly driven to move by the primary lifting unit, a support platform disposed on the slide rail assembly and movable along a first direction, and a secondary lifting unit disposed on the support platform; wherein the secondary lifting unit is disposed along a second direction and is connected to a plurality of support plates, the support plates being used to lift the battery module from the bottom of the battery module.

[0005] Multiple support plates can lift and support the battery module from the bottom, allowing for adjustment of the battery module in the first direction. The battery casing can be fitted onto the outer periphery of the battery module by removing the support plates one by one. Specifically, the primary lifting unit activates simultaneously, driving all support plates to rise and fall synchronously, thereby adjusting the position of the battery module in the first direction to bring the battery module and battery casing to the same height. Once the battery module is positioned correctly, the battery casing moves towards the battery module. When the battery module is partially inside the battery casing, the secondary lifting units activate one by one, causing the support plates at the bottom of the battery module to descend and separate from the bottom of the battery module, creating space for the battery casing to continue moving until the battery module is completely inside the battery casing, completing the module insertion process.

[0006] Preferably, the secondary lifting unit includes a plurality of first lifting units distributed along the second direction and a plurality of second lifting units distributed along the second direction. The output end of the first lifting unit is connected to the support plate, and the output end of the second lifting unit is connected to the support plate. The second direction is perpendicular to the first direction on a plane.

[0007] The secondary lifting unit includes a first lifting unit and a second lifting unit symmetrically distributed on both sides of the second direction. The output ends of the first lifting unit and the second lifting unit are respectively connected to a support plate. The first lifting unit and the second lifting unit work synchronously and drive the support plate down at the same time, which can make room for the battery casing to move, so that more of the battery module can enter the battery casing.

[0008] Preferably, the secondary lifting unit is connected to the support platform via a lateral moving unit, which can drive the secondary lifting unit to move along a third direction, which is perpendicular to both the first and second directions.

[0009] The lateral movement unit allows the secondary lifting unit and support plate to move along a third direction, effectively preventing collisions between the battery module, the secondary lifting unit and support plate and the battery casing during the installation process, ensuring a stable and orderly module installation operation.

[0010] Preferably, the support plate is connected to the secondary lifting unit via a centering unit, which can drive the support plate to move upward and center in the third position.

[0011] The centering unit allows the support plate to move upwards in the third direction, enabling the battery module supported by the support plate to be centered. This eliminates the need for separate centering structures on both sides of the module's supporting components, allowing the centering operation to be completed simultaneously when adjusting the battery module's height.

[0012] The present invention also provides a module housing device, including the aforementioned module carrying component, and further including a machine base, a housing moving component and a pressing component. The housing moving component is used to clamp and transport the battery housing, and the pressing component abuts against the battery module on the module carrying component. The battery module on the module carrying component and the battery housing on the housing moving component are at the same height.

[0013] The module support assembly can lift and support the battery module from the bottom of the battery module through multiple support plates, and adjust the battery module in the first direction so that the height of the battery module is consistent with the height of the housing moving assembly and the pressure assembly. Then, the housing moving assembly clamps and transports the battery housing, slowly bringing the battery housing closer to the battery module. At the same time, the pressure assembly abuts against the battery module from the other side. The multiple support plates can also be removed one by one to slowly fit the battery housing onto the outer periphery of the battery module until the battery module is completely inserted into the battery housing. More specifically, when the first-level lifting unit starts operating, it can simultaneously drive all the support plates to rise and fall synchronously, thereby adjusting the position of the battery module in the first direction so that the battery module and the battery casing are at the same height. After the position of the battery module is adjusted, the casing moving component drives the battery casing to move towards the battery module. When the battery module partially enters the battery casing, the second-level lifting unit starts operating one by one. The multiple support plates at the bottom of the battery module descend one by one and separate from the bottom of the battery module, making room so that the battery casing can continue to move until the battery module is completely inside the battery casing, completing the module installation operation.

[0014] Preferably, the housing moving assembly includes a housing driving unit connected to the machine tool and a housing clamping module driven by the housing driving unit to move in a second direction. The housing clamping module includes a clamping seat and a plurality of clamping units disposed on the clamping seat. The housing moving assembly also includes a guide plate, which is provided with a guide component for guiding the battery module into the battery housing.

[0015] The housing clamping module firmly clamps the battery housing and, driven by the housing driving unit, moves in the second direction, gradually approaching the battery module and eventually completely enveloping it.

[0016] Preferably, the guide assembly includes a first extension piece and a second extension piece, the first extension piece and the second extension piece being disposed opposite to each other and connected to the guide plate toward the side away from the battery module.

[0017] The guide plate and its guide components guide the battery module, ensuring accurate and reliable alignment with the opening in the battery casing and guaranteeing stable entry into the casing. The first and second extension plates further optimize the guiding function of the guide components, further ensuring reliability and guaranteeing stable entry of the battery module into the casing.

[0018] Preferably, the clamping seat is connected to the housing drive unit via a buffer slide rail, and the number of clamping units is three, which are distributed in an isosceles triangle.

[0019] The three clamping units, distributed in an isosceles triangle, fully utilize the axioms of mechanics and geometry to ensure the reliability of the battery casing fixation effect, prevent the battery casing from shifting during the installation and compression of the battery module, and ensure the module insertion operation proceeds smoothly.

[0020] The buffer slide rail provides a buffering effect for the movement of the housing moving component in the second direction, so that the battery housing can be buffered during the housing insertion process, effectively avoiding damage to the battery housing and battery module and improving product yield.

[0021] Preferably, the pressure counter assembly includes a pressure counter base connected to the machine tool, a pressure counter drive unit connected to the pressure counter base, and a pressure counter plate driven by the pressure counter drive unit to move along a second direction.

[0022] The pressure assembly is fixed on the machine base. The pressure plate is driven by the pressure drive unit and is pressed against the battery module to ensure that the battery module is stably inserted into the moving battery housing. During the module insertion operation, the center points of the mating surfaces of the battery housing, battery module and pressure plate are aligned in a straight line to ensure the stable operation of the module insertion.

[0023] The present invention also provides a module housing method, including Step 1: Place the battery module on the module support assembly and place the battery casing on the casing moving assembly; Step 2: Adjust the position of the battery module in the first and third directions of the module support assembly so that the battery module is aligned with the central axis of the second direction, the central axis of the opening of the battery casing, and the central axis of the pressure plate of the pressure assembly. Step 3: Press the pressure assembly close to the battery module and press it against one end face of the battery module; Step 4: The housing moving assembly moves the battery housing along the second direction toward the other end face of the battery module until the battery module partially enters the battery housing; Step 5: The secondary lifting units start operation one by one. The multiple support plates at the bottom of the battery module move down one by one and separate from the bottom of the battery module, making room so that the battery casing and the pressure-blocking components can move continuously until the battery module is completely inside the battery casing.

[0024] This module insertion method ensures that the battery casing, battery module, and pressure plate are aligned in a straight line, enabling rapid alignment and insertion. Furthermore, during the insertion and assembly process, the pressure on the battery casing and battery module is aligned along the same force line, effectively guaranteeing stable and reliable product assembly. The product is also subjected to uniform force, reducing the likelihood of deformation and other defects, resulting in better product quality.

[0025] The advantages of this invention compared to the prior art are: The module support assembly of this invention uses multiple support plates to lift and support the battery module from the bottom, enabling adjustment of the battery module in a first direction. The battery casing can be fitted onto the outer periphery of the battery module by removing the support plates one by one. Specifically, the primary lifting unit activates simultaneously, driving all support plates to rise and fall synchronously, thereby adjusting the position of the battery module in the first direction to bring the battery module and battery casing at the same height. Once the battery module is positioned correctly, the battery casing moves towards the battery module. When the battery module partially enters the battery casing, the secondary lifting units activate one by one, causing the support plates at the bottom of the battery module to descend and separate from the bottom of the battery module, creating space for the battery casing to continue moving until the battery module is completely inside the battery casing, completing the module insertion process.

[0041] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0042] The technical solutions in this application will now be described with reference to the accompanying drawings. Example 1

[0043] This embodiment provides a module support assembly 100, including a support base 110, a primary lifting unit 120 connected to the support base 110, a slide rail assembly 130 driven to move by the primary lifting unit 120, a support platform 140 disposed on the slide rail assembly 130 and movable in a first direction, a secondary lifting unit 150 disposed on the support platform 140, and a plurality of support plates 160 driven by the secondary lifting unit 150 and movable in the first direction, wherein the support plates 160 support the battery module from the bottom of the battery module.

[0044] Multiple support plates 160 can lift and support the battery module from the bottom, allowing for adjustment of the battery module in the first direction. The battery casing can be fitted onto the outer periphery of the battery module by removing the support plates 160 one by one. Specifically, the primary lifting unit 120 activates simultaneously, driving all support plates 160 to rise and fall synchronously, thereby adjusting the position of the battery module in the first direction to bring the battery module and battery casing to the same height. Once the battery module is positioned correctly, the battery casing moves towards the battery module. When the battery module partially enters the battery casing, the secondary lifting unit 150 activates one by one, causing the support plates 160 at the bottom of the battery module to descend and separate from the bottom of the battery module, creating space for the battery casing to continue moving until the battery module is fully inside the battery casing, completing the module insertion process.

[0045] The secondary lifting unit 150 includes a plurality of first lifting units 151 and a plurality of second lifting units 152 symmetrically distributed on both sides of the second direction. The second direction is perpendicular to the first direction on a plane. The output ends of the first lifting units 151 and the second lifting units 152 are respectively connected to a support plate 160.

[0046] The secondary lifting unit 150 includes a first lifting unit 151 and a second lifting unit 152 symmetrically distributed on both sides of the second direction. The output ends of the first lifting unit 151 and the second lifting unit 152 are respectively connected to a support plate 160. The first lifting unit 151 and the second lifting unit 152 work synchronously and drive the support plate 160 to descend at the same time, so that space can be made for the battery casing to move, so that more of the battery module can enter the battery casing.

[0047] In other embodiments, the secondary lifting unit 150 can be connected to the support platform 140 via a lateral moving unit, which can drive the secondary lifting unit 150 to move along a third direction, which is perpendicular to both the first and second directions.

[0048] The lateral movement unit allows the secondary lifting unit 150 and the support plate 160 to move along a third direction, effectively preventing collisions between the battery module, the secondary lifting unit 150 and the support plate 160 and the battery casing during the casing insertion process, ensuring the stable and orderly execution of the module casing insertion operation.

[0049] In other embodiments, the primary lifting unit 120 can be connected to the support 110 via a centering unit, which can drive the primary lifting unit 120 to move upward and center in a third direction.

[0050] The centering unit enables the primary lifting unit 120, the secondary lifting unit 150, the support plate 160, and the battery module to be centered in the third direction, thereby eliminating the need to set up separate centering structures on both sides of the module bearing component 100, and allowing the centering operation to be completed simultaneously when adjusting the height of the battery module. Example 2

[0051] This embodiment provides a module housing device, including a module carrying component 100 as in Embodiment 1, and also includes a machine base 200, a housing moving component 300, a pressing component 400, and a centering component 500. The housing moving component 300, the module carrying component 100, and the pressing component 400 are sequentially arranged on the machine base 200 along a second direction. The housing moving component 300 is used to clamp and transport the battery housing, and the pressing component 400 abuts against the battery module on the module carrying component 100.

[0052] The module support assembly 100 can lift and support the battery module from the bottom of the battery module through multiple support plates 160, and adjust the battery module in the first direction so that the height of the battery module is consistent with the height of the housing moving assembly 300 and the pressing assembly 400. Then, the housing moving assembly 300 clamps and transports the battery housing, slowly bringing the battery housing closer to the battery module. At the same time, the pressing assembly 400 abuts against the battery module from the other side. The multiple support plates 160 can also be removed one by one to slowly fit the battery housing onto the outer periphery of the battery module until the battery module is completely inserted into the battery housing. More specifically, when the first-level lifting unit 120 starts operating, it can simultaneously drive all the support plates 160 to rise and fall synchronously, thereby adjusting the position of the battery module in the first direction so that the battery module and the battery casing are at the same height. After the position of the battery module is adjusted, the casing moving component 300 drives the battery casing to move towards the battery module. When the battery module partially enters the battery casing, the second-level lifting unit 150 starts operating one by one, and the multiple support plates 160 at the bottom of the battery module descend one by one and separate from the bottom of the battery module, making room so that the battery casing can continue to move until the battery module is completely inside the battery casing, completing the module installation operation.

[0053] The housing moving assembly 300 includes a housing driving unit 310 connected to the machine base 200, and a housing clamping module 320 driven by the housing driving unit 310 to move in a second direction. The housing clamping module 320 includes a clamping seat 321 and a plurality of clamping units 322 disposed on the clamping seat 321.

[0054] The housing clamping module 320 firmly clamps the battery housing and, driven by the housing driving unit 310, moves in the second direction, gradually approaching the battery module and eventually completely enclosing it.

[0055] The housing moving assembly 300 also includes a guide plate 330, which has a guide component 331. The guide component 331 is used to guide the battery module into the battery housing. A first extension piece and a second extension piece 332 are respectively provided on both sides of the guide component 331. The first extension piece and the second extension piece 332 extend along a second direction.

[0056] The guide plate 330 and its guide component 331 guide the battery module, ensuring that the battery module is accurately and reliably aligned with the opening in the battery casing, and guaranteeing that the battery module enters the battery casing stably. The first extension piece and the second extension piece 332 further optimize the guiding function of the guide component 331, further ensuring the reliability of the guiding function and further guaranteeing that the battery module can enter the battery casing stably.

[0057] There are three clamping units 322, which are arranged in an isosceles triangle.

[0058] The three clamping units 322, distributed in an isosceles triangle, make full use of the axioms of mechanics and geometry to ensure the reliability of the battery casing fixation effect, prevent the battery casing from shifting during the installation and extrusion of the battery module, and ensure the module insertion operation proceeds smoothly.

[0059] The clamping seat 321 is connected to the housing drive unit 310 via the buffer slide rail 340.

[0060] The buffer slide rail 340 provides a buffering effect for the movement of the housing moving assembly 300 in the second direction, so that the battery housing can be buffered during the housing insertion process, effectively avoiding damage to the battery housing and battery module and improving product yield.

[0061] The pressure counter assembly 400 includes a pressure counter base 410 connected to the machine base 200, a pressure counter drive unit 420 connected to the pressure counter base 410, and a pressure counter plate 430 driven by the pressure counter drive unit 420 to move in a second direction.

[0062] The pressure assembly 400 is fixed on the machine base 200. The pressure plate 430 is driven by the pressure drive unit 420 and is pressed against the battery module to ensure that the battery module is stably inserted into the moving battery housing. During the module insertion operation, the center points of the mating surfaces of the battery housing, battery module and pressure plate form a straight line to ensure the stable operation of the module insertion. Example 3

[0063] This embodiment provides a module installation method based on the module installation device in Embodiment 2, including... Step 1: Place the battery module on the module support assembly 100 and place the battery casing on the casing moving assembly 300; Step 2: The module support assembly 100 adjusts the position of the battery module in the first direction so that the battery module is aligned with the opening of the battery casing; Step 3: Press the pressure assembly 400 close to the battery module and press it against the side of the battery module; Step 4: The housing moving assembly 300 moves the battery housing toward the battery module along the second direction until the battery module partially enters the battery housing; Step 5: The secondary lifting unit 150 starts operation one by one, and the multiple support plates 160 at the bottom of the battery module move down one by one and separate from the bottom of the battery module, making room so that the battery casing can continue to move until the battery module is completely inside the battery casing.

[0064] This module insertion method ensures that the battery casing, battery module, and pressure plate are aligned in a straight line, enabling rapid alignment and insertion. Furthermore, during the insertion and assembly process, the pressure on the battery casing and battery module is aligned along the same force line, effectively guaranteeing stable and reliable product assembly. The product is also subjected to uniform force, reducing the likelihood of deformation and other defects, resulting in better product quality.

[0065] The aforementioned drive units can be motors or cylinders, which provide power. The clamping units can be grippers or cylinders, which are all existing technologies and not the inventive points of this invention, so they will not be described in detail.

[0066] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
