Description
Technical Field
[0001] This application relates to the field of battery manufacturing technology, and in particular to a casing assembly device. Background Technology
[0002] The battery casing includes a housing and end caps that fit over the housing, which are typically fixed together by welding. To improve the reliability of the subsequently manufactured battery, related technologies involve pressing the end caps into the housing (where no electrode components are located), then welding them together before sending the battery for metallographic analysis. This reduces the possibility of welding defects affecting battery performance.
[0003] However, since no electrode assembly is placed inside the housing, the end cap has a large degree of freedom when it is pressed into the housing through the opening, making it prone to tilting and affecting the assembly quality of the housing. Utility Model Content
[0004] The main objective of this application is to provide a housing assembly apparatus configured to press-fit the end cap of the housing into the housing, aiming to reduce the possibility of end cap misalignment during the pressing process and improve the assembly quality of the housing.
[0005] To achieve the above objectives, the housing assembly apparatus proposed in this application includes:
[0006] The first carrier has a first bearing surface on one side in the first direction; and
[0007] The second carrier is slidably connected to the first carrier along the first direction and has an extended state and a retracted state. When the second carrier is in the extended state, the second carrier protrudes from the first bearing surface and is configured to form a first positioning groove with the first bearing surface. The first positioning groove is configured to place an end cap.
[0008] The second carrier has a second bearing surface, which faces the same side as the first bearing surface. The second bearing surface is configured to hold the housing.
[0009] The housing assembly device of this application, in use, can accommodate a positioning end cap by means of a first positioning groove formed by the second carrier in its extended state and the first bearing surface of the first carrier; then, by driving the housing located on the second bearing surface of the second carrier to slide and retract the second carrier, the end cap can be pressed into the housing. Furthermore, during the pressing process, the second carrier slides along with the housing, ensuring that it can position the end cap throughout the pressing process. This reduces the possibility of the end cap tilting during pressing, thereby improving the assembly quality of the housing.
[0010] In some embodiments, the first carrier includes a first portion and a second portion. The first portion has a first bearing surface. The second portion is connected to the first portion, and the second carrier is connected to the first portion and / or the second portion. When the second carrier is in an extended state, the second portion protrudes from the second bearing surface, and the second portion and the second bearing surface are configured to form a second positioning groove, which is configured to hold the housing. Thus, the first positioning groove and the second positioning groove can respectively position the end cap and the housing, further improving their stability during press-fitting and enhancing the assembly quality of the housing.
[0011] In some embodiments, the second carrier and the second part are annular structures and are disposed around the first bearing surface. Thus, the second carrier and the second part can respectively position the end cap and the housing at various points in the circumferential direction, thereby improving the positioning effect on the end cap and the housing.
[0012] In some embodiments, the first part includes a base plate and a boss; the boss protrudes from one side of the base plate in a first direction, and a first bearing surface is provided on the side of the boss facing away from the base plate; the second part is connected to the base plate, and the second carrier is connected to the base plate and / or the second part. Thus, a step can be formed at the connection between the base plate and the boss to provide sufficient space for the sliding second carrier, thereby improving the compactness of the second carrier mounted on the first carrier.
[0013] In some embodiments, the second carrier and the boss are spaced apart. This reduces the possibility of the second carrier getting stuck due to friction with the boss during sliding, improves the smoothness of the second carrier's sliding, and facilitates the smooth pressing of the end cap and the housing.
[0014] In some embodiments, the distance between the second carrier and the boss is defined as d1, satisfying the relationship: 0.05 mm ≤ d1 ≤ 0.1 mm. This allows for a better balance between the smoothness of the second carrier's sliding and its positioning effect.
[0015] In some embodiments, on a projection plane perpendicular to the first direction, the projection of the end cap is located inside the projection of the boss. This improves the load-bearing capacity of the boss on the end cap and allows the second carrier located around the boss to form a gap with the end cap, thus facilitating the placement of the end cap into the first positioning groove formed by the second carrier and the boss.
[0016] In some embodiments, the distance between the edge of the boss and the edge of the end cap is defined as d2, satisfying the relationship: 0.15 mm ≤ d2 ≤ 0.25 mm. This ensures that the distance d2 between the edge of the boss and the edge of the end cap is not too small, which would result in an excessively small gap between the second carrier and the end cap, affecting the placement of the end cap; simultaneously, it also ensures that the distance d2 between the edge of the boss and the edge of the end cap is not too large, which would result in an excessively large gap between the second carrier and the end cap, affecting the positioning effect of the end cap.
[0017] In some embodiments, in the first direction, the thickness of the second carrier is defined as h1, and the thickness of the boss is defined as h2, satisfying the relationship: h1 = h2. This ensures that when the second carrier moves with the housing to abut against the base plate, the second bearing surface and the first bearing surface are flush, allowing the end face of the housing with the opening to be flush with the surface of the end cap facing the first bearing surface, further improving the assembly quality of the housing.
[0018] In some embodiments, the housing assembly device further includes an elastic element disposed between the second carrier and the base plate. Thus, after the end cap and housing are press-fitted, the elastic element can be reset under its deformation force, thereby automatically resetting the second carrier for the next press-fitting operation.
[0019] In some embodiments, a first groove is provided on the side of the second carrier facing the base plate, and a second groove is provided on the base plate corresponding to the position of the first groove; one end of the elastic member is accommodated in the first groove, and the other end is accommodated in the second groove. Thus, the first groove and the second groove can accommodate both ends of the elastic member, so that the elastic member can be stably disposed between the second carrier and the pressure plate, thereby stably driving the second carrier to perform the reset operation.
[0020] In some embodiments, the second carrier is an annular structure and is arranged around the boss; the number of elastic elements is multiple, and the multiple elastic elements are arranged circumferentially around the boss. This facilitates uniform support of the second carrier at multiple positions in the circumferential direction, and allows for stable sliding reset of the second carrier. Furthermore, different types and / or different numbers of elastic elements can be installed to accommodate different pressing forces applied to the end cap and the shell.
[0021] In some embodiments, the elastic element is a spring. This improves the elasticity of the elastic element and the ease of its installation.
[0022] In some embodiments, the second part includes a side plate and a pressure plate. The side plate is connected to the bottom plate and is spaced apart from the boss in a second direction, which intersects the first direction. The pressure plate is connected to the side plate and is spaced apart from the bottom plate in the first direction. A portion of the second carrier is disposed between the pressure plate and the bottom plate, and a portion of the second bearing surface of the pressure plate and the second carrier is configured to form a second positioning groove. Thus, the second carrier and the elastic element can be clamped and installed by the cooperation of the pressure plate and the bottom plate, thereby improving the ease of installation of the second carrier and the elastic element. Simultaneously, since the pressure plate can cover a portion of the second bearing surface of the second carrier, the volume of the second carrier can be set relatively large without affecting the positioning effect of the second part on the housing, thus facilitating the setting of the second carrier to a suitable volume.
[0023] In some embodiments, when the second carrier is in the extended state, the second bearing surface abuts against the pressure plate. Thus, the pressure plate can limit the reset stroke of the second carrier, ensuring that the height of the second carrier protruding from the first bearing surface after each reset is exactly the thickness of the end cap.
[0024] In some embodiments, the pressure plate and the housing are spaced apart. This allows the housing to be easily placed into the second positioning groove formed by the pressure plate and the second carrier. Furthermore, since the open end of the housing expands after the end cap is pressed into the housing, the spaced arrangement between the pressure plate and the housing also reduces the likelihood of the housing being jammed by the pressure plate after pressing.
[0025] In some embodiments, the distance between the pressure plate and the housing is defined as d3, satisfying the relationship: 0.3 mm ≤ d3 ≤ 0.5 mm. This ensures that the distance d3 between the pressure plate and the housing is not too small, which would result in an excessively small gap between the pressure plate and the housing, affecting the placement of the housing; simultaneously, it also ensures that the distance d3 between the pressure plate and the housing is not too large, which would result in an excessively large gap between the pressure plate and the housing, affecting the positioning effect of the housing.
[0026] In some embodiments, the thickness of the pressure plate in the first direction is defined as h3, satisfying the relationship: 15 mm ≤ h3 ≤ 30 mm. This ensures that the thickness h3 of the pressure plate is not too small, which would affect the positioning effect on the housing, and that the thickness h3 is not too large, which would affect the placement and removal of the housing.
[0027] In some embodiments, the pressure plate is an annular structure and is arranged around the circumference of the boss; the pressure plate has four corners, and the inner side of each corner is provided with a clearance notch, which penetrates both sides of the pressure plate in the first direction. Thus, the clearance notch provided on the inner side of the four corners of the pressure plate can accommodate the expansion of the housing after pressing, reducing the possibility of the housing getting stuck.
[0028] In some embodiments, the side plate and the second carrier are spaced apart. This prevents the side plate from causing frictional effects on the sliding of the second carrier, thereby improving the smoothness of the sliding of the second carrier.
[0029] In some embodiments, the side panel and the base plate are detachably connected. This allows the side panel and the base plate to be disassembled when maintenance or replacement of parts is required.
[0030] In some embodiments, the housing assembly apparatus further includes a body and a drive mechanism. A first carrier is disposed on the body; the drive mechanism is disposed on the body and spaced apart from the first carrier in a first direction. The drive mechanism is configured to drive the housing to retract the second carrier. Thus, the body facilitates the assembly of the various parts of the housing assembly apparatus into a single unit for use, improving the ease of use of the housing assembly apparatus. The drive mechanism is conveniently used to control the movement of the housing to compress the second carrier to complete the press-fitting of the end cap and the housing.
[0031] In some embodiments, the drive mechanism includes a cylinder and a push plate. The cylinder is located on the machine body, and the push plate is connected to the cylinder and configured to abut against the housing. And / or, the housing assembly device further includes a control switch, located on the machine body and electrically connected to the drive mechanism, configured to control the opening and closing of the drive mechanism. Thus, the cylinder can automatically provide driving force, reducing the labor intensity of the operator. It also simplifies the structure of the drive mechanism. Furthermore, the push plate increases the contact area between the drive mechanism and the push plate, reducing the possibility of pressure damage to the housing. The control switch facilitates manual control by the operator, thereby improving the human controllability of the housing assembly device. Attached Figure Description

[0047] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation
[0048] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0049] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.
[0050] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0051] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the word "and / or" throughout the text means including three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of a person skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.
[0052] Batteries, which are devices used to store electrical energy, are widely used not only in energy storage power systems such as hydroelectric, thermal, wind, and solar power plants, but also in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in other fields. A battery cell is the smallest unit that makes up a battery, typically consisting of a casing and electrode components housed within the casing.
[0053] Electrode components are the parts in a battery cell where the actual electrochemical reaction takes place. They can include a positive electrode, a negative electrode, and a separator located between them, and are formed by winding or stacking the positive electrode, negative electrode, and separator.
[0054] The outer casing serves to house and protect the electrode assembly. It can include a housing with an opening at one end and an end cap that covers the opening of the housing; the two are typically fixed together by welding. Furthermore, to improve the reliability of the subsequently manufactured battery, related technologies often press the end cap into the housing without the electrode assembly, then weld them together before sending them for metallographic analysis. This reduces the possibility of welding defects affecting battery performance.
[0055] However, since no electrode assembly is placed inside the housing, the end cap cannot be effectively supported and limited when it is pressed into the housing through the opening, resulting in a relatively large degree of freedom. This makes the end cap prone to tilting, affecting the assembly quality of the housing and causing misjudgments in subsequent metallographic analysis.
[0056] Therefore, based on the above considerations, in order to solve the problem of easy skewing when pressing end caps into a housing without electrode components in related technologies, this application proposes a housing assembly device. This housing assembly device uses a slidable second carrier and a first carrier's first bearing surface to form a first positioning groove for placing the end cap. The housing is placed through the second bearing surface of the second carrier, and the end cap is pressed into the housing by driving the housing to retract the second carrier. Simultaneously, by the second carrier following the sliding of the housing, the end cap is positioned throughout the pressing process, reducing the possibility of end cap skewing.
[0057] In addition, it should be noted that the casing assembly device proposed in this application can be used to assemble the casing of a battery cell as described above, or it can be used to assemble the casing of other products.
[0058] The structure of the housing assembly device proposed in this application will be explained and illustrated below with examples:
[0059] Please refer to the reference. Figures 1 to 6In one embodiment of this application, the shell assembly device 100 proposed in this application includes a first carrier 10 and a second carrier 20. The first carrier 10 has a first bearing surface 1131 on one side in a first direction. The second carrier 20 is slidably connected to the first carrier 10 along the first direction and has an extended state and a retracted state. When the second carrier 20 is in the extended state, the second carrier 20 protrudes from the first bearing surface 1131 and is configured with the first bearing surface 1131 to form a first positioning groove 20a. The first positioning groove 20a is configured to place an end cap 203. The second carrier 20 has a second bearing surface 21, which faces the same side as the first bearing surface 1131. The second bearing surface 21 is configured to place a shell 201.
[0060] The first carrier 10 can support the end cap 203 via a first bearing surface 1131 formed in a first direction. When the housing assembly device 100 is in normal installation and use, with the ground as a reference, this first direction can be vertical. Therefore, the first bearing surface 1131 can be formed from the upper surface of the first carrier 10. Of course, this first direction can also be horizontal, or an inclined direction intersecting the vertical and horizontal directions; this application does not limit the specific type of the first direction. The first bearing surface 1131, on a projection plane perpendicular to the first direction, can have a projection area larger than the projection area of the end cap 203, or it can be smaller than or equal to the projection area of the end cap 203; this application does not limit the size relationship between the two. Furthermore, since the end cap 203 is typically equipped with an explosion-proof valve for pressure relief and an electrode post for electrical connection to the external electrode assembly, a valve clearance hole 111b and an electrode post clearance hole 111c can be provided on the first bearing surface 1131, such as... Figure 7 As shown. Alternatively, the first carrier 10 may include a first portion 11 and a second portion 13, as described below, with the first portion 11 forming the first bearing surface 1131. Of course, the first carrier 10 may also consist only of the first portion 11. Furthermore, on the projection plane perpendicular to the first direction, the shape of the first carrier 10 may be any shape, such as a square, rectangle, or circle.
[0061] The second carrier 20 is slidably disposed on the first carrier 10 and has an extended state and a retracted state. The extended state is when the second carrier 20 is not abutted or driven by the housing 201. In this state, the second carrier 20 and the first bearing surface 1131 of the first carrier 10 can be configured to enclose the first positioning groove 20a for accommodating the positioning end cap 203. The retracted state is when the second carrier 20 is abutted or driven by the housing 201. In this state, the end cap 203 is pressed into the housing 201. For example, when the first direction is vertical and the first bearing surface 1131 is facing upwards, the housing 201 can be placed on the second bearing surface 21 of the second carrier 20 with its opening facing downwards. Then, when the housing 201 is pressed down, the second carrier 20 moves downwards and retracts. At this time, the end cap 203 can be said to move upwards relative to the housing 201, and thus can be pressed into the housing 201. Furthermore, the second carrier 20 can be a ring structure as described below. Of course, the second carrier 20 can also be a block structure or a column structure, and multiple carriers can be provided to be distributed on each side of the first bearing surface 1131. For example, the second carrier 20 can be a block structure, and four carriers can be provided to be distributed around the first bearing surface 1131 to position the end cap 203 around the perimeter. In addition, the second carrier 20 can be provided on the side where the first carrier 10 is connected to the first bearing surface 1131, or the second carrier 20 can be directly provided on the first bearing surface 1131. In this case, the first bearing surface 1131 can be provided with a groove to provide movement space for the second carrier 20.
[0062] In use, the outer casing assembly device 100 of this application can accommodate the positioning end cap 203 by means of a first positioning groove 20a formed by the second carrier 20 in its extended state and the first bearing surface 1131 of the first carrier 10. Figures 3 to 5 As shown; then, by driving the housing 201 located on the second bearing surface 21 of the second carrier 20 to slide and retract the second carrier 20, the end cap 203 can be pressed into the housing 201, as shown. Figure 6 As shown. Furthermore, during the process of pressing the end cap 203 into the housing 201, the second carrier 20 slides along with the housing 201, so that it can position the end cap 203 throughout the pressing process. This reduces the possibility of the end cap 203 becoming misaligned during the pressing process, thereby improving the assembly quality of the housing 200.
[0063] Please refer to the reference. Figure 3 and Figure 4In one embodiment of this application, the first carrier 10 includes a first part 11 and a second part 13. The first part 11 is provided with a first bearing surface 1131. The second part 13 is connected to the first part 11, and the second carrier 20 is connected to the first part 11 and / or the second part 13. When the second carrier 20 is in an extended state, the second part 13 protrudes from the second bearing surface 21, and the second part 13 and the second bearing surface 21 are configured to form a second positioning groove 133a. The second positioning groove 133a is configured to place the housing 201.
[0064] The first part 11 can be used to form the first bearing surface 1131. The first part 11 can be, as described below, a base plate 111 and a boss 113 protruding from the base plate 111, with the boss 113 forming the first bearing surface 1131. Alternatively, the first part 11 can also consist only of the base plate 111, with the base plate 111 forming the first bearing surface 1131.
[0065] The second part 13 can be used to enclose the second bearing surface 21 of the second carrier 20 to form a second positioning groove 133a for accommodating the positioning housing 201. The second part 13 can be a ring structure as described below. Alternatively, the second part 13 can be a block structure or a column structure, and multiple parts can be provided to be distributed on each side of the first bearing surface 1131. For example, the second part 13 can be a block structure, and four parts can be provided to be distributed around the perimeter of the first bearing surface 1131 to position the housing 201. Furthermore, the second part 13 can include a side plate 131 and a pressure plate 133 arranged at an angle, as described below. The side plate 131 is connected to the first part 11, and the pressure plate 133 is arranged in the first direction with the second carrier 20. The pressure plate 133 and a portion of the second bearing surface 21 are enclosed to form the second positioning groove 133a. Of course, the second part 13 may also consist only of the side plate 131, which is configured to form the second positioning groove 133a by the complete enclosure of the side plate 131 and the second bearing surface 21.
[0066] In this embodiment, the first carrier 10 is configured to include a first portion 11 and a second portion 13, such that the first portion 11 can be configured to enclose the second carrier 20 to form a first positioning groove 20a, and the second portion 13 can be configured to enclose the second carrier 20 to form a second positioning groove 133a. The first positioning groove 20a and the second positioning groove 133a can respectively position the end cap 203 and the housing 201, further improving their stability during press-fitting and enhancing the assembly quality of the housing 200. It should be noted that in other embodiments, the first carrier 10 may only include the first portion 11, in which case the groove can be directly provided on the second carrier 20 to position the housing 201.
[0067] Please refer to the reference. Figure 3 , Figure 4 , Figure 7 , Figure 8 as well as Figure 10 As shown, in one embodiment of this application, the second carrier 20 and the second part 13 are annular structures and are arranged around the first bearing surface 1131.
[0068] In this embodiment, both the second carrier 20 and the second part 13 are arranged in a ring shape, so that the second carrier 20 and the second part 13 can respectively position the end cap 203 and the housing 201 at various points in the circumferential direction, thereby improving the positioning effect of the end cap 203 and the housing 201. At the same time, the number of the second carrier 20 and the second part 13 can each be set to one, which helps to simplify the number of parts and improve the convenience of assembling the housing assembly device 100.
[0069] Please refer to the reference. Figure 3 , Figure 4 as well as Figure 7 As shown, in one embodiment of this application, the first part 11 includes a base plate 111 and a boss 113; the boss 113 protrudes from one side of the base plate 111 in a first direction, and the side of the boss 113 facing away from the base plate 111 is provided with a first bearing surface 1131; the second part 13 is connected to the base plate 111, and the second carrier 20 is connected to the base plate 111 and / or the second part 13.
[0070] In this embodiment, the first part 11 is configured to include a base plate 111 and a boss 113, such that a step can be formed at the connection between the base plate 111 and the boss 113, so as to provide corresponding moving space to set up a sliding second carrier 20, thereby improving the compactness of the second carrier 20 set on the first carrier 10.
[0071] Please refer to the reference. Figure 3 and Figure 4 In one embodiment of this application, the second carrier 20 and the boss 113 are spaced apart.
[0072] In this embodiment, the second carrier 20 and the boss 113 are spaced apart, which can reduce the possibility of friction and jamming between the second carrier 20 and the boss 113 during the sliding process, improve the smoothness of the sliding of the second carrier 20, so as to smoothly complete the pressing of the end cap 203 and the housing 201.
[0073] Please refer to the reference. Figure 4 and Figure 5 In one embodiment of this application, the distance between the second carrier 20 and the boss 113 is defined as d1, which satisfies the relationship: 0.05 mm ≤ d1 ≤ 0.1 mm.
[0074] In this embodiment, the distance d1 between the second carrier 20 and the boss 113 is set to 0.05 mm to 0.1 mm. This ensures that the distance between the second carrier 20 and the boss 113 is not too small, which would affect the sliding avoidance effect of the second carrier 20; and that the distance between the second carrier 20 and the boss 113 is not too large, which would affect the positioning effect of the second carrier 20 on the end cap 203. In other words, this range of d1 can better balance the smoothness of the sliding of the second carrier 20 and the positioning effect. The value of d1 can be 0.05 mm, 0.06 mm, 0.07 mm, 0.08 mm, 0.09 mm, or 0.1 mm, or any value within the above range.
[0075] Please refer to the reference. Figure 4 and Figure 5 In one embodiment of this application, on a projection plane perpendicular to the first direction, the projection of the end cap 203 is located inside the projection of the boss 113.
[0076] The projection of the end cap 203 is located inside the projection of the boss 113, that is, the length and width of the boss 113 are both greater than the length and width of the end cap 203.
[0077] In this embodiment, the length and width of the boss 113 are set to be greater than the length and width of the end cap 203. On the one hand, this can improve the load-bearing capacity of the boss 113 on the end cap 203. On the other hand, it can also make the second carrier 20 located on the periphery of the boss 113 form a gap with the end cap 203, thereby facilitating the placement of the end cap 203 into the first positioning groove 20a formed by the second carrier 20 and the boss 113.
[0078] Please refer to the reference. Figure 4 and Figure 5 In one embodiment of this application, the distance between the edge of the boss 113 and the edge of the end cap 203 is defined as d2, which satisfies the relationship: 0.15 mm ≤ d2 ≤ 0.25 mm.
[0079] In this embodiment, the length and width of the boss 113 are set to be 0.15 mm to 0.25 mm larger than the length and width of the end cap 203. This ensures that the distance d2 between the edge of the boss 113 and the edge of the end cap 203 is not too small, which would result in an excessively small gap between the second carrier 20 and the end cap 203, thus affecting the placement of the end cap 203. At the same time, this also ensures that the distance d2 between the edge of the boss 113 and the edge of the end cap 203 is not too large, which would result in an excessively large gap between the second carrier 20 and the end cap 203, thus affecting the positioning effect of the end cap 203. The value of d2 can be 0.15 mm, 0.16 mm, 0.17 mm, 0.18 mm, 0.19 mm, 0.2 mm, 0.21 mm, 0.22 mm, 0.23 mm, 0.24 mm, or 0.25 mm, or any value within the above range.
[0080] Please refer to the reference. Figure 4 and Figure 5 In one embodiment of this application, in the first direction, the thickness of the second carrier 20 is defined as h1, and the thickness of the boss 113 is defined as h2, satisfying the relationship: h1=h2.
[0081] In this embodiment, the thickness h1 of the second carrier 20 and the thickness h2 of the boss 113 are set to be equal, so that when the second carrier 20 moves with the housing 201 to abut against the bottom plate 111, the second bearing surface 21 and the first bearing surface 1131 are flush, so that the end face of the housing 201 with the opening can be flush with the surface of the end cover 203 facing the first bearing surface 1131, further improving the assembly quality of the outer shell 200.
[0082] Please refer to the reference. Figure 3 and Figure 4 In one embodiment of this application, the outer shell assembly device 100 further includes an elastic element 30, which is disposed between the second carrier 20 and the base plate 111.
[0083] The elastic element 30 is an object that can automatically return to its original position after being deformed by force. The elastic element 30 can be a spring as described below, or it can be a sheet spring; this application does not limit the type of elastic element 30. Furthermore, the elastic element 30 is disposed between the second carrier 20 and the base plate 111, including cases where both ends of the elastic element 30 are fixed to the second carrier 20 and the base plate 111 respectively, and cases where both ends of the elastic element 30 abut against the second carrier 20 and the base plate 111 respectively.
[0084] In this embodiment, an elastic element 30 is provided between the second carrier 20 and the base plate 111, so that the second carrier 20 can compress the elastic element 30 when sliding with the housing 201, so that the elastic element 30 forms a deformation elastic force. After the end cap 203 and the housing 201 are pressed together, the elastic element 30 can be reset under the action of its deformation elastic force, thereby driving the second carrier 20 to automatically reset for the next pressing operation. Of course, it should be noted that in other embodiments, when the elastic element 30 is not provided, the second carrier 20 may be connected to a toggle rod, so as to drive the second carrier 20 to reset through the toggle rod. It can even be further provided with a mechanism to drive the toggle rod, so as to drive the toggle rod to slide synchronously with the housing 201.
[0085] Please refer to the reference. Figure 3 and Figure 4 ,as well as Figures 7 to 9 In one embodiment of this application, the second carrier 20 is provided with a first groove 20b on the side facing the base plate 111, and the base plate 111 is provided with a second groove 111a at the position corresponding to the first groove 20b; one end of the elastic member 30 is accommodated in the first groove 20b, and the other end is accommodated in the second groove 111a.
[0086] In this embodiment, the first groove 20b and the second groove 111a can accommodate both ends of the elastic member 30, so that the elastic member 30 can be stably disposed between the second carrier 20 and the pressure plate 133, thereby stably driving the second carrier 20 to perform the reset operation.
[0087] Please refer to the reference. Figure 3 and Figure 4 ,as well as Figures 8 to 9 In one embodiment of this application, the second carrier 20 is a ring structure and is arranged around the boss 113; there are multiple elastic elements 30, which are arranged around the boss 113 in a circumferential direction.
[0088] In this embodiment, multiple elastic elements 30 are provided to facilitate uniform support of the second carrier 20 at multiple positions in the circumferential direction, and to ensure stable sliding reset of the second carrier 20. Furthermore, since the second part 13 and the first part 11 are detachably connected as described below, different types and / or numbers of elastic elements 30 can be installed to accommodate different pressing forces applied to the end cap 203 and the shell. It should also be noted that when the second carrier 20 is configured as a block structure or column structure as described above, and there are multiple of them, at least one elastic element 30 can be provided between the base plate 111 and each second carrier 20.
[0089] Please refer to the reference. Figure 3and Figure 4 In one embodiment of this application, the elastic element 30 is a spring.
[0090] In this embodiment, the elastic element 30 is set as a spring, which has good elastic properties and is easy to arrange, thereby improving the elastic force effect of the elastic element 30 and the convenience of its installation.
[0091] Please refer to the reference. Figure 3 and Figure 4 In one embodiment of this application, the second part 13 includes a side plate 131 and a pressure plate 133. The side plate 131 is connected to the bottom plate 111 and is spaced apart from the boss 113 in a second direction, which intersects the first direction. The pressure plate 133 is connected to the side plate 131 and is spaced apart from the bottom plate 111 in a first direction. A portion of the second carrier 20 is disposed between the pressure plate 133 and the bottom plate 111. The pressure plate 133 and a portion of the second bearing surface 21 of the second carrier 20 are configured to form a second positioning groove 133a.
[0092] When the first direction is up and down as described above, the second direction can be horizontal.
[0093] In this embodiment, the second part 13 is configured to include a side plate 131 and a pressure plate 133, allowing the second carrier 20 and the elastic element 30 described above to be clamped and installed through the cooperation of the pressure plate 133 and the bottom plate 111, thereby improving the ease of installation of the second carrier 20 and the elastic element 30. Simultaneously, since the pressure plate 133 can cover a portion of the second bearing surface 21 of the second carrier 20, the volume of the second carrier 20 can be set relatively large without affecting the positioning effect of the second part 13 on the housing 201, thus facilitating the setting of the second carrier 20 to a suitable volume, further improving the ease of installation of the second carrier 20 itself and the associated elastic element 30.
[0094] Please refer to the reference. Figure 3 and Figure 4 In one embodiment of this application, when the second carrier 20 is in the extended state, the second bearing surface 21 abuts against the pressure plate 133.
[0095] In this embodiment, the second bearing surface 21 is set to abut against the pressure plate 133, so that the second carrier 20 is slidably compressed by the housing 201. Then, when it is automatically reset under the action of the elastic element 30 described above, the pressure plate 133 can limit the reset stroke of the second carrier 20, so that the height of the second carrier 20 protruding from the first bearing surface 1131 after each reset is exactly the thickness of the end cap 203.
[0096] Please refer to the reference. Figure 3 and Figure 4In one embodiment of this application, the pressure plate 133 and the housing 201 are spaced apart.
[0097] The pressure plate 133 and the housing 201 are spaced apart, meaning that when the housing 201 is placed within the second positioning groove 133a formed by the pressure plate 133 and the second carrier 20, they will not contact each other. When the second part 13 is an annular structure as described above, that is, on the projection plane perpendicular to the first direction, the projection of the housing 201 is located inside the projection of the pressure plate 133, and the length and width dimensions of the inner side of the pressure plate 133 are both greater than the length and width dimensions of the housing 201, respectively.
[0098] In this embodiment, the pressure plate 133 and the housing 201 are spaced apart, which facilitates the placement of the housing 201 into the second positioning groove 133a formed by the pressure plate 133 and the second carrier 20. Moreover, since the end cap 203 expands at the open end of the housing 201 after being pressed into it, the spaced arrangement between the pressure plate 133 and the housing 201 also reduces the chance of the housing 201 being stuck by the pressure plate 133 after pressing.
[0099] Please refer to the reference. Figure 4 and Figure 5 In one embodiment of this application, the distance between the pressure plate 133 and the housing 201 is defined as d3, which satisfies the relationship: 0.3 mm ≤ d3 ≤ 0.5 mm.
[0100] In this embodiment, the distance d3 between the pressure plate 133 and the housing 201 is set to 0.3 mm to 0.5 mm. This ensures that the distance d3 is not too small, which would result in an insufficient gap between the pressure plate 133 and the housing 201, affecting the placement of the housing 201; at the same time, it also ensures that the distance d3 is not too large, which would result in an excessive gap between the pressure plate 133 and the housing 201, affecting the positioning effect of the housing 201. The value of d3 can be 0.3 mm, 0.35 mm, 0.4 mm, 0.45 mm, or 0.5 mm, or any value within the above range.
[0101] Please refer to the reference. Figure 4 and Figure 5 In one embodiment of this application, the thickness of the pressure plate 133 is defined as h3 in the first direction, satisfying the relationship: 15 mm ≤ h3 ≤ 30 mm.
[0102] In this embodiment, the thickness h3 of the pressure plate 133 is set to between 15 mm and 30 mm. This ensures that the thickness h3 is not too small, which would affect the positioning effect on the housing 201. Simultaneously, it also ensures that the thickness h3 is not too large, which would affect the placement and removal of the housing 201. The thickness h3 of the pressure plate 133 can be 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, 20 mm, 21 mm, 22 mm, 23 mm, 24 mm, 25 mm, 26 mm, 27 mm, 28 mm, 29 mm, or 30 mm, or any value within the above range.
[0103] Please refer to the reference. Figures 10 to 12 In one embodiment of this application, the pressure plate 133 is an annular structure and is arranged around the circumference of the boss 113; the pressure plate 133 has four corners 133b, and the inner side of the corners 133b is provided with a clearance notch 133c, which penetrates the pressure plate 133 on both sides in the first direction.
[0104] In this embodiment, clearance notches 133c are provided on the inner side of the four corners 133b of the pressure plate 133, which can avoid the expansion of the housing 201 after the press-fit is completed, reducing the possibility of the housing 201 getting stuck.
[0105] Please refer to the reference. Figure 3 and Figure 4 In one embodiment of this application, the side plate 131 and the second carrier 20 are spaced apart.
[0106] In this embodiment, a gap is provided between the side plate 131 and the second carrier 20 so that the side plate 131 will not cause friction to the sliding of the second carrier 20, thereby improving the smoothness of the sliding of the second carrier 20.
[0107] In one embodiment of this application, the side plate 131 and the bottom plate 111 are detachably connected.
[0108] The connection is detachable, meaning that it can still be disassembled and removed after the connection and assembly are completed. The side plate 131 and the base plate 111 can be connected by screws as described below, or by snap-fit or magnetic connection, etc. This application does not limit the detachable connection method of the side plate 131 and the base plate 111.
[0109] In this embodiment, the side plate 131 and the bottom plate 111 are configured to be detachably connected, so that when it is necessary to repair or replace parts (e.g., the first part 11, the second part 13, the second carrier 20 or the elastic element 30), the side plate 131 and the bottom plate 111 can be disassembled.
[0110] In one embodiment of this application, the side plate 131 and the bottom plate 111 are connected by screws.
[0111] A threaded connector is an object connected by threads. The threaded connector can be a screw, in which case it can pass through the side plate 131 and be threaded to the base plate 111. Alternatively, the threaded connector can pass through the side plate 131 and the base plate 111 sequentially and be threaded to the body 40 as described below. Of course, the threaded connector can also be a combination of a bolt and a nut, in which case the bolt can pass through the side plate 131 and the base plate 111 sequentially, and then be tightened with a nut.
[0112] In this embodiment, the side plate 131 and the bottom plate 111 are connected by screws, which makes the connection structure between the two simpler and thus improves the convenience of connecting the side plate 131 and the bottom plate 111.
[0113] In one embodiment of this application, the side plate 131 can also be configured as a ring structure, similar to the pressure plate 133, to improve the overall strength of the second part 13. In this case, there can be multiple screw fasteners, which are arranged around the circumference of the side plate 131 to improve the stability of the connection between the side plate 131 and the base plate 111.
[0114] Please refer to Figure 1 In one embodiment of this application, the outer shell assembly device 100 further includes a body 40 and a drive mechanism 50. The first carrier 10 is disposed on the body 40; the drive mechanism 50 is disposed on the body 40 and is spaced apart from the first carrier 10 in a first direction. The drive mechanism 50 is configured to drive the housing 201 to retract the second carrier 20.
[0115] The body 40 can be used to provide mounting positions for mounting the first carrier 10 and the drive mechanism 50, so that the various parts of the outer shell assembly device 100 can be assembled into a whole. The body 40 can be a frame structure formed by multiple columns or a combination of multiple columns and plates, or it can be a box structure, etc. This application does not limit the structural type of the body 40.
[0116] The drive mechanism 50 can be used to drive the housing 201 to press the second carrier 20, thereby achieving the press-fitting of the end cap 203 and the housing 201. The drive mechanism 50 can be, as described below, a cylinder 51, with the extension end of a lead screw driving the housing 201 to press the second carrier 20. Alternatively, the drive mechanism 50 can include a motor, a lead screw, and a slide mounted on the lead screw, with the slide driving the housing 201 to press the second carrier 20. Or, the drive mechanism 50 can include an operating lever and a linkage assembly, with the operator driving the operating lever to drive the housing 201 to press the second carrier 20 via the linkage assembly. Therefore, this application does not limit the structural type of the drive mechanism 50.
[0117] In this embodiment, the body 40 facilitates the assembly of the various parts of the outer casing assembly device 100 into a whole for use, improving the ease of use of the outer casing assembly device 100. The drive mechanism 50 is conveniently used to control the movement of the housing 201 to press the second carrier 20 to complete the pressing of the end cap 203 and the housing 201.
[0118] Please refer to Figure 1 In one embodiment of this application, the drive mechanism 50 includes a cylinder 51 and a push plate 53. The cylinder 51 is disposed on the body 40, and the push plate 53 is connected to the cylinder 51 and configured to abut against the housing 201.
[0119] In this embodiment, the drive mechanism 50 is configured to include a cylinder 51, which automatically provides driving force, reducing the labor intensity of the operator. This also simplifies the structure of the drive mechanism 50. Furthermore, the addition of a push plate 53 increases the contact area between the drive mechanism 50 and the push plate 53, reducing the possibility of pressure damage to the housing 201.
[0120] Please refer to Figure 1 In one embodiment of this application, the housing assembly device 100 further includes a control switch 60, which is disposed on the body 40 and electrically connected to the drive mechanism 50. The control switch 60 is configured to control the opening and closing of the drive mechanism 50.
[0121] The control switch 60 can be used to control the opening and closing of the drive mechanism 50, that is, the opening and closing of the cylinder 51 in the drive mechanism 50 described above. Therefore, the control switch 60 can be electrically connected to the cylinder 51. The control switch 60 can be a push-button switch or a rotary switch; this application does not limit the type of control switch 60.
[0122] In this embodiment, by setting the control switch 60, it is convenient for operators to manually control the device, thereby improving the human controllability of the operation of the housing assembly device 100.
[0123] Please refer to Figure 1In one embodiment of this application, the body 40 may include a first support base 41, a second support base 43, a third support base 45, a column 47, and an adjusting rod. The first support base 41 and the second support base 43 may be spaced apart in a first direction, and the two ends of the column 47 may be connected to the first support base 41 and the second support base 43 respectively. The third support base 45 is slidably sleeved on the column 47 along the first direction and is located between the first support base 41 and the second support base 43. The two ends of the adjusting rod may be rotatably connected to the first support base 41 and the second support base 43 respectively, and pass through the third support base 45. The adjusting rod and the third support base 45 are threadedly connected. The first carrier 10 may be disposed on the third support base 45, and the driving mechanism 50 may be disposed on the second support base 43. Thus, by rotating the adjusting column 49, the third support base 45 can be driven to slide along the first direction, thereby driving the first carrier 10 to slide along the first direction, realizing the adjustment of the height position of the first carrier 10 to adapt to the assembly of the outer shell 200 of different heights.
