Description

Technical Field

[0001] This invention relates to the field of battery packaging technology, and in particular to a module re-pressing and boxing device and method. Background Technology

[0002] In battery modules, separators are placed between adjacent battery cells or between battery cells and other components, providing heat insulation and electrical insulation. Separators can also be placed between two battery modules for the same purpose. Furthermore, separators can be bonded and fixed to adjacent components using structural adhesive, effectively improving the structural strength of the entire battery module or the connection strength between adjacent battery modules.

[0003] However, after the battery modules are installed into the battery pack using an over-pressurized method, and then disassembled for testing, structural adhesive dendritic defects are often found, leading to modal failure. The structural stability and safety performance of the battery pack are lower than expected.

[0004] Therefore, there is an urgent need for a module re-pressing device and method to solve the above-mentioned technical problems. Summary of the Invention

[0005] One object of the present invention is to provide a module re-pressing device that can reduce or avoid dendritic defects in structural adhesive, thereby ensuring the structural stability and safety performance of the battery pack.

[0006] To achieve this objective, the first aspect of the present invention adopts the following technical solution: The module re-pressing and boxing device includes: The first clamping assembly includes two first clamping members, which are adjustablely spaced along a preset first direction. The first clamping members are capable of abutting against the side wall surface of the workpiece to be placed in the box, which is perpendicular to the preset first direction, to apply a first preset pressure. The second clamping assembly includes two second clamping members, which are adjustablely spaced along a preset second direction. The second clamping members are used to abut against the side wall surface of the workpiece to be placed in the box, which is perpendicular to the preset second direction, to apply a second preset pressure. A clamping space is defined between the two second clamping members and the two first clamping members. A fixing component is used to fix one end face of the workpiece to be placed in the box along a preset third direction, so as to fix the workpiece to be placed in the box in the clamping space. The preset first direction, the preset second direction and the preset third direction are arranged perpendicularly to each other. A bracket assembly, along the preset third direction, has the first clamping component, the second clamping component, and the fixing component installed at one end of the bracket assembly, and the other end of the bracket assembly is used to connect to a driving device, which is used to move the module repressing box device; The control unit is signal-connected to the first clamping assembly and the second clamping assembly. After a preset portion of the workpiece to be placed into the box enters the box structure, the control unit is configured to send a signal to the first clamping assembly to increase the first preset pressure and maintain it for a preset time, and to send a signal to the second clamping assembly to decrease the second preset pressure.

[0007] Another objective of this invention is to provide a method for re-pressing modules into a box, which can reduce or avoid dendritic defects in structural adhesives and ensure the structural stability and safety performance of the battery pack.

[0008] To achieve this objective, the second aspect of the present invention adopts the following technical solution: The module re-pressing and boxing method includes: The workpieces to be placed in the box are spaced apart from the box structure along a preset third direction, and the preset third direction is perpendicular to the preset inlet of the box structure; The workpiece to be placed in the box is moved along the preset third direction until a preset portion of the workpiece enters the box structure through the preset inlet; and, during the process of the preset portion passing through the preset inlet, a first preset pressure is applied to a pair of oppositely arranged side walls of the workpiece to be placed in the box along a preset first direction, and a second preset pressure is applied to another pair of oppositely arranged side walls of the workpiece to be placed in the box along a preset second direction, wherein the preset first direction is perpendicular to the preset third direction and perpendicular to the adhesive partition in the workpiece to be placed in the box, and the preset second direction is perpendicular to the preset third direction and parallel to the adhesive partition; After the preset part enters the preset inlet, the second preset pressure is reduced, the first preset pressure is increased and maintained for a preset time, then the first preset pressure and the second preset pressure are released, and the remaining part of the workpiece to be placed into the box is sent into the box structure.

[0009] The above technical solution has the following advantages or beneficial effects: Compared to the conventional overpressure packing method described above, this module repressure packing method reduces the second preset pressure, increases the first preset pressure, and maintains it for a preset time. This causes the distribution of the structural adhesive and the deformation of the battery module to be altered before the first and second preset pressures are released. Consequently, after the first and second preset pressures are released, the flow requirement of the structural adhesive along the preset second direction is reduced, avoiding dendritic defects in the solidified structural adhesive layer. This ensures a tight bond between the separator, structural adhesive, and individual battery cells, thereby guaranteeing the structural stability and safety of the battery pack.

[0010] The module re-pressing and boxing device enables the above-mentioned module re-pressing and boxing method to be implemented by controlling the first clamping component and the second clamping component during the module boxing process. This ultimately reduces or even avoids dendritic defects, ensuring that the separator, structural adhesive and individual cells are tightly bonded and fixed, thereby guaranteeing the structural stability and safety of the battery pack.

[0013] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0014] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," "fixed," and "abutting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0015] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0016] In the description of this embodiment, the terms "upper," "lower," "right," and "left," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0017] The battery pack assembly process includes three steps: assembly and shaping, module cleaning, and module placement. During assembly and shaping, multiple individual battery cells are placed within the module frame according to the required quantity, arrangement, and connection method. Specifically, multiple individual cells are first arranged, and then shaping pressure is applied to the neatly arranged cells using shaping fixtures or equipment. While maintaining this pressure, structural components such as end plates and side plates are fixedly connected to form the module frame, establishing a stable mechanical structure. This provides the basic structural strength and rigidity for the battery module, enabling it to withstand subsequent handling, vibration, and impact. (Refer to...) Figure 1 As shown, in related technologies, individual battery cells are often arranged along their thickness direction to form a cell assembly 11, and then multiple rows of cell assemblies 11 are arranged along the length direction of the individual battery cells. A separator 12 is often provided between two adjacent rows of cell assemblies 11. The separator 12 can play a role in heat insulation and insulation, and both sides of the separator 12 are coated with structural adhesive, thereby bonding and fixing the cell assembly 11 and the separator 12 together, thereby further improving the structural strength of the battery module.

[0018] Module cleaning involves cleaning the metal surfaces of the battery module that require bonding or welding, thereby improving the quality and reliability of bonding or welding between the battery module and related components during battery pack assembly. For example, plasma cleaning can be used for surface cleaning and activation in related technologies.

[0019] Module installation involves placing the assembled battery modules into the battery pack's housing structure 2 (e.g., the lower housing), completing initial fixing and connection to ensure the battery modules and housing structure 2 do not shift during subsequent processes and transportation. (Refer to...) Figure 2 As shown, the related technology provides a method of over-pressurization into the battery pack, which involves simultaneously applying a clamping force to the battery module along both the thickness and length directions of the individual battery cells (e.g., ...). Figure 2 As indicated by the small arrows F1 and F2, the battery module deforms, slightly reducing its outer dimensions. It then enters the lower housing through the pre-set inlet 20. As the clamping force is gradually released, the battery module abuts against the four side walls of the housing structure 2, achieving initial fixation and connection between the battery module and the housing structure 2. However, during this process, the expansion caused by the release of clamping force leads to van der Waals forces damaging the structural adhesive. This negatively impacts the adhesive, causing localized tearing of the initially solidified adhesive layer, resulting in dendritic defects. Consequently, the bonding area between the separator 12 and the individual battery cells decreases, reducing bonding stability.

[0020] Therefore, several embodiments of the present invention provide a module re-pressing and boxing device and method. It should be noted that this module re-pressing and boxing method can be applied to placing battery modules into a box structure 2, or to directly placing a battery-like module structure (e.g., a CTP battery pack) formed by bonding multiple cell groups 11 and separators 12 into the box structure 2. Specifically, the module re-pressing and boxing method includes: S1. The workpiece 1 to be placed in the box is set at a distance from the box structure 2 along a preset third direction, and the preset third direction is perpendicular to the preset inlet 20 of the box structure 2.

[0021] Specifically, in step S1, the workpiece 1 to be placed in the box can be either a single battery module or a battery module-like structure composed of a cell group 11 and a separator 12 bonded together. The box structure 2 can be the upper box of the battery pack, the lower box, or a box-shaped structure integrally set on the vehicle chassis. The preset inlet 20 of the box structure 2 is the channel through which the workpiece 1 to be placed in the box enters the box structure 2, and it is generally a rectangular opening. The preset third direction is perpendicular to the preset inlet 20, that is, the direction perpendicular to the rectangular opening.

[0022] S2. Move the workpiece 1 to be placed in the box along a preset third direction until a preset portion 101 of the workpiece 1 to be placed in the box enters the box structure 2 through the preset inlet 20; and, during the process of the preset portion 101 passing through the preset inlet 20, apply a first preset pressure (such as...) to a pair of oppositely arranged sidewalls of the workpiece 1 to be placed in the box along a preset first direction. Figure 2 (As shown by the small arrow F1), and along the preset second direction, a second preset pressure is applied to the other pair of side walls opposite to the workpiece 1 to be placed in the box (such as...). Figure 2 (As shown by the small arrow F2), the first preset direction is perpendicular to the third preset direction and perpendicular to the adhesive partition 12 in the workpiece 1 to be placed in the box, and the second preset direction is perpendicular to the third preset direction and parallel to the adhesive partition 12.

[0023] Specifically, in step S2, the adhesive-coated separator 12 refers to a separator 12 disposed between the battery cell groups 11 and coated with structural adhesive, which can bond and fix the two battery cell groups 11 located on both sides of the adhesive-coated separator 12. The adhesive-coated separator 12 is arranged parallel to the aforementioned preset third direction, the preset first direction is perpendicular to the adhesive-coated separator 12, and the preset second direction is parallel to the adhesive-coated separator 12.

[0024] Taking a battery module as an example, when a first preset pressure is applied to a pair of oppositely arranged sidewalls of the workpiece 1 to be placed in the box, and a second preset pressure is applied to another pair of oppositely arranged sidewalls of the workpiece 1 to be placed in the box, the outer contour size of the battery module can be reduced due to the pressure, thereby allowing the preset portion 101 of the battery module to easily enter the box structure 2. For example, by clamping and pressing the sidewalls other than the preset portion 101 of the workpiece 1 to be placed in the box in a clamping manner, the aforementioned first and second preset pressures can be applied without interference.

[0025] S3. After the preset part 101 enters the preset inlet 20, reduce the second preset pressure, increase the first preset pressure and maintain it for a preset time, then release the first preset pressure and the second preset pressure, and send the remaining part 102 of the workpiece 1 to be put into the box structure 2.

[0026] Specifically, in step S3, refer to Figure 2 , Figure 3 As shown, reducing the second preset pressure means decreasing the second preset pressure from its initial value compared to step S2, while increasing the first preset pressure means increasing it from its initial value. This invention does not specifically limit the initial values ​​of the first and second preset pressures, as long as the preset portion 101 can deform to enter the preset inlet 20. It should be noted that... Figure 3 The solid black arrow in the text indicates that the first preset pressure has a higher pressure value in step S3 compared to step S2.

[0027] Compared to the conventional overpressure loading method described above, this method reduces the second preset pressure, increases the first preset pressure, and maintains it for a preset time. This alters the distribution of the structural adhesive and the deformation of the battery module before releasing the first and second preset pressures. Consequently, after releasing the first and second preset pressures, the flow requirement of the structural adhesive along the preset second direction is reduced, preventing dendritic defects in the solidified structural adhesive layer. For example, in some embodiments, the initial value of the second preset pressure is not less than 1000 kgf, and when the first preset pressure is increased, the second preset pressure decreases to 300-500 kgf, while the first preset pressure increases to 300-400 kgf.

[0028] In contrast, if the remaining portion 102 is directly fed into the housing structure 2 after step S2 and the first and second preset pressures are released, the remaining portion 102 will undergo significant expansion along the preset second direction when the second preset pressure is released. Furthermore, the flowability of the structural adhesive will continuously decrease over time, making it difficult to meet the large flow demand caused by the significant deformation. This results in tearing and difficult-to-fill cracks, leading to the aforementioned dendritic defects. However, by reducing the second preset pressure, increasing the first preset pressure, and maintaining this pressure for a preset time, the degree of deformation when the second preset pressure is released can be reduced. Additionally, by increasing the first preset pressure, the structural adhesive is driven to flow into the cracks caused by the reduction in the second preset pressure, ultimately reducing or even avoiding dendritic defects. This ensures a tight bond between the separator 12, the structural adhesive, and the individual battery cells, thereby guaranteeing the structural stability and safety of the battery pack. It should be noted that the second preset pressure can be reduced to 300kfg-500kfg first, and then the first preset pressure can be increased; or the second preset pressure can be reduced and the first preset pressure increased simultaneously; or the first preset pressure can be increased first, and then the second preset pressure can be reduced. The correlation between the first and second preset pressures can be achieved through a mechanical transmission structure or through program control. As long as the effect of reducing or avoiding dendritic defects can be achieved, it falls within the scope of protection of this invention.

[0029] Preferably, in some embodiments, the aforementioned preset third direction is a vertical direction, while the preset first direction and preset second direction are both parallel to the horizontal plane. Along the preset third direction, a suction cup structure 61 is adsorbed onto the end face of the workpiece 1 to be placed in the box, away from the preset box opening 20, so as to control the distance between the workpiece 1 to be placed in the box and the box structure 2 by means of adsorption force. The use of the suction cup structure 61 can avoid the situation that affects the passage of the remaining part 102 through the preset box opening 20 in step S3, and can stably control the moving speed of the workpiece 1 to be placed in the box, which is beneficial to improving the boxing efficiency and assembly quality.

[0030] Furthermore, in some embodiments, after maintaining the preset time, the first preset pressure and the second preset pressure are gradually released, and the remaining portion 102 is fed into the box structure 2. During the gradual release, the first preset pressure and the second preset pressure can decrease linearly or curvilinearly. As long as they decrease continuously, time can be provided for the flow of the structural adhesive, thereby further reducing and avoiding dendritic defects.

[0031] It should be noted that the aforementioned preset time is related to various factors such as the type of structural adhesive, spraying method, and ambient temperature and humidity; therefore, this invention does not impose specific limitations on it. For example, in this embodiment, Debon PU2117F structural adhesive is used, and the preset time is 2-7 seconds. It is understood that the stronger the fluidity of the structural adhesive, the shorter the preset time, which is more conducive to improving production efficiency. Simultaneously, the faster the curing speed of the structural adhesive (of course, it should not be completely cured during the loading process; for example, the curing time of Debon PU2117F structural adhesive is generally 15 minutes), the longer the preset time, thereby fully regulating the distribution state of the structural adhesive and reducing dendritic defects.

[0032] Since the structural adhesive gradually solidifies during the assembly and shaping process until the module is placed in the box, to ensure that the increased first preset pressure can effectively drive the flow of the structural adhesive, after the preset portion 101 enters the preset inlet 20, the first preset pressure is increased until it is not less than the shaping pressure along the preset first direction experienced by the workpiece 1 to be placed in the box during the assembly and shaping process. For example, in some embodiments, this shaping pressure is not less than 200 kgf, therefore the first preset pressure is not less than 200 kgf, such as 250 kgf, 300 kgf, 400 kgf, etc. Optionally, the first preset pressure is not greater than 400 kgf to avoid excessive deformation that could break the vacuum between the workpiece and the suction cup structure 61.

[0033] Similarly, the preset portion 101 is also related to various factors such as the type of structural adhesive and the structure of the individual battery cell, so it is not specifically limited in this invention. For example, in this invention, taking the battery module structure formed by bonding two battery cell groups 11 and the adhesive-coated separator 12 as an example, along the preset third direction, the height dimension of the preset portion 101 is one-quarter to one-third of the height dimension of the workpiece 1 to be placed in the box, so that after the preset portion 101 of the workpiece 1 to be placed in the box enters the box structure 2, it avoids large pressure between the preset portion 101 and the box structure 2, and also avoids large pressure on the remaining portion 102 when it is subjected to the first preset pressure and the second preset pressure, thereby preventing local pressure damage to the individual battery cell.

[0034] Furthermore, the first preset pressure is applied at least to the portion of the remaining 102 that is away from the box structure 2 along a preset third direction. This is because the aforementioned expansion deformation mainly occurs in the portion of the remaining 102 that is away from the box structure 2. Therefore, as long as the first preset pressure can redistribute the structural adhesive in this portion, the effect of reducing and avoiding dendritic defects can be achieved.

[0035] In one embodiment of the present invention, a module re-pressing and boxing device is also provided for implementing the above-described module re-pressing and boxing method. The device includes a first clamping assembly 4, a second clamping assembly 5, a fixing assembly 6, a support assembly 3, and a control unit (not shown in the figure). The support assembly 3 is used to mount the first clamping assembly 4, the second clamping assembly 5, and the fixing assembly 6. The fixing assembly 6 can fix the workpiece 1 to be boxed between the first clamping assembly 4 and the second clamping assembly 5. The first clamping assembly 4 is used to apply the above-described first preset pressure to the workpiece 1 to be boxed, while the second clamping assembly 5 is used to implement the above-described second preset pressure. The control unit is signal-connected to the first clamping assembly 4 and the second clamping assembly 5, and after the preset portion 101 enters the box structure 2, it can send a signal to the first clamping assembly 4 to increase the first preset pressure and maintain it for a preset time, and send a signal to the second clamping assembly 5 to decrease the second preset pressure, thereby implementing the above-described module re-pressing and boxing method.

[0036] like Figure 4 , Figure 5 As shown, in some embodiments, along a preset third direction, one end of the support assembly 3 is connected to the first clamping assembly 4, the second clamping assembly 5 and the fixing assembly 6, and the other end of the support assembly 3 is provided with a connector, through which it can be connected to a drive device such as a robot, thereby moving the module pressing box device as a whole.

[0037] The first clamping assembly 4 includes two first clamping members 41, which are adjustablely spaced along a preset first direction. When the distance between the two first clamping members 41 decreases until they simultaneously abut against the side wall surface of the workpiece 1 to be placed in the box, perpendicular to the preset first direction, a first preset pressure can be applied to the workpiece 1. Similarly, the second clamping assembly 5 includes two second clamping members 51, which are adjustablely spaced along a preset second direction. When the distance between the two second clamping members 51 decreases until they simultaneously abut against the side wall surface of the workpiece 1 to be placed in the box, perpendicular to the preset second direction, a second preset pressure can be applied to the workpiece 1. A clamping space is defined between the two first clamping members 41 and the two second clamping members 51. The fixing assembly 6 can be fixedly connected to one end face of the workpiece 1 to be placed in the box along a preset third direction, thereby fixing the workpiece 1 to be placed in the box within the clamping space. This allows the first clamping members 41 and the second clamping members 51 to move until they abut against the side wall of the workpiece 1 to be placed in the box, thereby applying a first preset pressure and a second preset pressure. Optionally, the fixing assembly 6 includes a plurality of suction cup structures 61, which can be fixedly connected to the workpiece 1 to be placed in the box by adsorption.

[0038] This device enables the module re-pressing method during the module loading process by controlling the first clamping component 4 and the second clamping component 5. This reduces or even avoids dendritic defects, ensuring a tight bond between the separator 12, structural adhesive, and individual cells, thereby guaranteeing the structural stability and safety of the battery pack.

[0039] Optionally, such as Figure 4 As shown, in some embodiments, the module re-pressing box device further includes a first spacing adjustment component 7, which is connected between the first clamping component 4 and the support component 3. The first spacing adjustment component 7 is used to adjust the spacing between the first clamping component 4 and the support component 3 along a preset third direction, so that the first clamping member 41 can accurately abut against the remaining part 102 of the workpiece 1 to be boxed, and can be applied to various workpieces 1 of different sizes to be boxed.

[0040] For example, the first pitch adjustment assembly 7 includes a first adjustment seat 71, a first support member 72, and a first pitch drive member 73. The first adjustment seat 71 is fixedly connected to the support assembly 3 and to the first pitch drive member 73. The first pitch drive member 73 is a linear motor or cylinder, its output end is fixedly connected to the first support member 72, and it is capable of moving the first support member 72 along a preset third direction. The first support member 72 and the aforementioned first clamping member 41 are movably connected along a preset first direction, thereby ensuring that the movement of the first clamping member 41 along the preset first direction is not disturbed by the pitch adjustment process.

[0041] Optionally, in some embodiments, the first spacing adjustment assembly 7 further includes a first slide rail pair 74. The first slide rail pair 74 includes a guide rail and a slider. The guide rail is fixedly connected to the first adjustment seat 71 and extends along a preset third direction. The slider is slidably connected to the guide rail and fixedly connected to the first support member 72. By placing the first slide rail pair 74 between the first adjustment seat 71 and the first support member 72, the first support member 72 (and the first clamping member 41 connected thereto) can be accurately guided to move along a preset third direction during the spacing adjustment process, thereby facilitating accurate quantitative adjustment of the first preset pressure.

[0042] Further, in some embodiments, the first clamping assembly 4 includes a first driving member 42. The first driving member 42 is fixedly connected to the first support member 72 and is throttle connected to the first clamping member 41. The first driving member 42 may adopt a linear module or similar structure, which can move the first clamping member 41 along a preset first direction, thereby implementing the aforementioned first preset pressure. Preferably, a second slide rail pair 44 is also connected between the first clamping member 41 and the first support member 72. The length direction of the guide rail in the second slide rail pair 44 is set along the preset first direction, which can guide the movement direction of the first clamping member 41 and reduce the load of the first driving member 42 along a preset third direction. The structure of the second slide rail pair 44 is similar to that of the first slide rail pair 74, and will not be described in detail in this invention.

[0043] like Figure 6 As shown, in some embodiments, the first clamping assembly 4 further includes a clamping pad 43, which is connected to one end of the first clamping member 41 near the workpiece 1 to be placed in the box. The clamping pad 43 is used to directly abut against the workpiece 1 to apply a first preset pressure, and along a preset second direction, the length of the clamping pad 43 is not less than the length of the adhesive partition 12 in the workpiece 1 to be placed in the box, so that the first preset pressure can be uniformly applied to the side wall surface of the workpiece 1 to be placed in the box along the preset second direction, avoiding the occurrence of local dendritic defects.

[0044] Optionally, in some other embodiments, the clamping pad 43 described above can also be replaced with a pressure roller structure, that is, a pressure roller is provided at the end of the first clamping member 41 near the workpiece 1 to be placed in the box, and the axial direction of the pressure roller is arranged along a preset second direction. The pressure roller can also achieve the effect of applying a first preset pressure, and therefore also falls within the scope of protection of this invention.

[0045] It is understandable that, since the second preset pressure is mainly used to achieve changes in the outer contour dimensions of the workpiece 1 to be placed in the box, in some embodiments, the second clamping member 51 can be a finger-type clamping member, that is, by having multiple finger portions 511 abut against the workpiece 1 to be placed in the box. Of course, in some embodiments, the second clamping member 51 can also adopt a similar manner to the first clamping member 41, abutting against the workpiece 1 to be placed in the box continuously and with a large area, which can also achieve changes in the outer contour dimensions of the workpiece 1 to be placed in the box. Therefore, the specific structure of the second clamping member 51 is not limited in this invention.

[0046] like Figure 7As shown, in some embodiments, the second clamping assembly 5 includes a second driving member 52, which is fixedly connected to the bracket assembly 3. The second driving member 52 is kinetically connected to the second clamping member 51 and can drive the second clamping member 51 to move along a preset second direction. Optionally, a third slide rail pair 53 is connected between the second clamping member 51 and the bracket assembly 3. The length direction of the guide rail in the third slide rail pair 53 is along the preset second direction, which can guide the movement direction of the second clamping member 51 and reduce the load of the second driving member 52 along the preset third direction. The structure of the third slide rail pair 53 is similar to that of the first slide rail pair 74, and will not be described in detail in this invention.

[0047] like Figure 8 As shown, the module re-pressing box device includes a second spacing adjustment component 8, which is connected between the fixing component 6 and the support component 3. The second spacing adjustment component 8 is used to adjust the spacing between the fixing component 6 and the support component 3 along a preset third direction.

[0048] Specifically, the second spacing adjustment assembly 8 includes a second support member 81, a second spacing adjustment member 82, a linear bearing 83, and a guide shaft 84. The linear axis is fixedly connected to the support assembly 3, and the guide shaft 84 passes through the linear bearing 83 and extends along a preset third direction. One end of the guide shaft 84 is fixedly connected to one side of the second support member 81, while the other side of the second support member 81 is connected to the aforementioned fixing assembly 6. The second spacing adjustment member 82 is fixedly connected to the support assembly 3, and its output end is fixedly connected to the second support member 81, thereby moving the fixing assembly 6 along a preset third direction, changing the spacing between the fixing assembly 6 and the support assembly 3, and adapting to the needs of workpieces 1 of different sizes to be placed in the box.

[0049] For example, in some embodiments, when using the above-described module repressing box-in device, the distance between the first clamping members 41 and the distance between the second clamping members 51 are first increased to meet the requirements for the workpiece 1 to be boxed to enter the clamping space. Then, the distance between the fixing member 6 and the support member 3 is adjusted to a suitable distance by the second distance adjustment component 8, so that the workpiece 1 to be boxed can be fixed by the fixing member 6 and is in a position that can be stably clamped by the second clamping member 51. Then, the workpiece 1 to be boxed is clamped by the second clamping component 5, and the distance between the first clamping member 41 and the support member 3 is adjusted by the first distance adjustment component 7, so that the first clamping member 41 can clamp the end of the remaining part 102 that is away from the preset part 101. Then, the workpiece 1 to be boxed is clamped by the first clamping component 4. At this time, the process of fixing the workpiece 1 to be boxed to the module repressing box-in device is completed.

[0050] Then, the module repressing and boxing device is moved by the driving device, so that the workpiece 1 to be boxed is moved to the vicinity of the preset box inlet 20 and is spaced apart from the preset box inlet 20 along a preset third direction, thus implementing the above-mentioned module repressing and boxing method. Specifically, in some embodiments, a first preset pressure and a second preset pressure are initially applied, and the workpiece 1 to be boxed is moved along a preset third direction so that the preset portion 101 can pass through the preset box inlet 20. Then, the first preset pressure is gradually increased to 300 kgf-400 kgf, and the second preset pressure is gradually decreased to 300 kgf-500 kgf, and maintained for a preset time of 7 seconds. Then, upon contact with the first preset pressure and the second preset pressure, the first clamping member 41 and the second clamping member 51 are both moved away from the workpiece 1 to be boxed, and the workpiece 1 to be boxed is lifted into the box structure 2 only under the adsorption force of the suction cup structure 61.

[0051] Optionally, in some embodiments, to further improve the accuracy of controlling the first preset pressure, a pressure sensor can be provided at the first clamping member 41, or a pressure sensor can be provided within the first driving member 42. The pressure sensor is signal-connected to the control unit described above. When the control unit detects through the pressure sensor that the first preset pressure has increased to a suitable level, it can send a signal to the first clamping assembly 4 to maintain the first preset pressure for a preset time. The location of the pressure sensor is not specifically limited in this invention, as long as it can accurately measure the first preset pressure.

[0052] It should be noted that the aforementioned control unit can be a host computer, such as a PLC, or a controller with similar functions. For example, when the first drive unit 42 is a servo motor, the servo motor driver can be used as the control unit. Optionally, in some embodiments, the controller of the drive device, such as the robot's controller, can also be used as the control unit. Therefore, the control unit is not specifically limited in this invention. As long as it can issue the aforementioned signal to increase the first preset pressure and maintain it for a preset time, and the signal to decrease the second preset pressure, it falls within the protection scope of the control unit to be protected by this invention.
