Description

Technical Field

[0001] The present application relates to the technical field of automation equipment, and in particular to an assembly device for electronic equipment. Background Art

[0002] Flexible electrical connection structures typically use flexible insulating substrates, such as polyimide, polyester, or other polymer materials, instead of traditional rigid substrates. These structures offer many advantages over rigid electrical connection structures. For example, they can bend, roll, and fold freely, meeting the needs of electronic products moving toward higher density, miniaturization, and higher reliability. Consequently, they are widely used in electronic devices.

[0003] In the related art, during the production process of electronic equipment, an automated device can be used to assemble the flexible electrical connection structure in the electronic equipment. The use of an automated assembly production method is conducive to improving assembly efficiency and assembly consistency. In order to ensure the connection stability of the flexible electrical connection structure, the flexible electrical connection structure is usually reasonably designed with a certain amount of redundancy. However, due to the poor management effect of the redundant parts of the flexible electrical connection structure during the automated assembly process, the connection position of the flexible electrical connection structure is prone to loosening or connection failure, and other poor assembly problems. It may even cause the battery of the electronic device to become warped and loose, thereby reducing the product qualification rate of the electronic device. Summary of the Invention

[0004] The present application provides an assembly device for electronic equipment, which is used to solve the problem that poor assembly is likely to occur during the process of assembling a flexible electrical connection structure by the assembly device.

[0005] To achieve the above objectives, the embodiments of the present application adopt the following technical solutions:

[0006] In a first aspect, an embodiment of the present application provides an assembly device for an electronic device, which is used to assemble a front shell and a circuit board assembly of the electronic device. The circuit board assembly includes a first circuit board assembly, a second circuit board assembly, and a flexible electrical connection structure. The first circuit board assembly and the second circuit board assembly are arranged on the inner surface of the front shell and are spaced apart. The flexible electrical connection structure is electrically connected between the first circuit board assembly and the second circuit board assembly.

[0007] The assembly device includes a first working unit and a first driving component. The first working unit is used to be arranged on the side of the flexible electrical connection structure facing away from the front shell. The first working unit includes a first working piece and a second working piece arranged along a first direction. The first direction is consistent with the direction in which the first end of the flexible electrical connection structure points to the second end. The end of the flexible electrical connection structure connected to the first circuit board assembly is the first end, and the end of the flexible electrical connection structure connected to the second circuit board assembly is the second end; the first driving component is used to drive the first working piece and the second working piece to move in directions away from each other, so that the first working piece moves toward the first end and the second working piece moves toward the second end.

[0008] According to the assembly device of the embodiment of the present application, there is a redundant part between the first end and the second end of the flexible electrical connection structure. In the process of the first driving component driving the first working piece to move toward the first end, the first working piece can gradually adjust the partial redundancy of the flexible electrical connection structure toward the position close to the first end. In the process of the first driving component driving the second working piece to move toward the second end, the second working piece can gradually adjust the partial redundancy of the flexible electrical connection structure toward the position close to the second end. This can ensure that the flexible electrical connection structure has a certain amount of redundancy at the position close to the first electrical connection component and the position close to the second electrical connection component, so as to avoid the asymmetric distribution of the redundancy of the flexible electrical connection structure during the assembly process of the electronic device, causing excessive tension on the first end or the second end, resulting in unstable connection with the first circuit board assembly or the second circuit board assembly, and avoiding the problem of loosening of the connection position, which is conducive to improving the problem of poor assembly and improving the connection quality between circuit board assemblies.

[0009] In addition, adjusting the redundant part of the flexible electrical connection structure toward a position close to the first end and the second end can also avoid excessive redundancy in the middle part of the flexible electrical connection structure, thereby avoiding excessive bending of the flexible electrical connection structure during the subsequent assembly process of the electronic device, and avoiding excessive redundant parts squeezing the battery to cause it to warp and loosen, thereby reducing the resulting product failure rate.

[0010] In some optional embodiments, the end of the first working member facing the flexible electrical connection structure is the third end, and the end of the first working member facing away from the flexible electrical connection structure is the fourth end. The third end includes a first side surface and a second side surface, with the first side surface facing the second working member and the second side surface facing away from the second working member. The distance from the first side surface to the second side surface gradually decreases along a direction from the fourth end toward the third end.

[0011] In this way, the first working piece can have more movement space without increasing the size of the overall device, which expands the travel range of the first working piece along the first direction. When the first working piece adjusts the redundant part of the flexible electrical connection structure, it is beneficial to increase the adjustment range; in addition, it also helps to optimize the matching relationship between the first working piece and the flexible electrical connection structure, for example, it helps to optimize the contact angle and pressure.

[0012] In some optional embodiments, along a direction from the fourth end to the third end, the first side surface extends obliquely toward a direction away from the second working piece.

[0013] In this way, the interference between the first working piece and surrounding components can be reduced, which is conducive to improving the operational flexibility of the first working piece.

[0014] In some optional embodiments, a storage compartment is provided on the inner surface of the front housing, the first circuit board assembly and the second circuit board assembly are located on opposite sides of the storage compartment, and a portion of the flexible electrical connection structure is located within the storage compartment. The second side surface is adapted to mate with an inner side surface of the storage compartment adjacent to the first circuit board assembly.

[0015] In this way, during the movement of the first working piece toward the first end, the assembly device can control the position of the first working piece by means of the matching relationship between the second side surface and the inner side surface of the accommodating bin adapted thereto, so as to achieve accurate control of the travel range of the first working piece, thereby facilitating the control of the adjustment range of the redundant part of the flexible electrical connection structure.

[0016] In some optional embodiments, along the direction from the first end to the second end, the size of the accommodating bin is L1, the stroke of the first working piece moving toward the first end is L2, the stroke of the second working piece moving toward the second end is L3, and the ratio of L2 to L1 and the ratio of L3 to L1 are both greater than or equal to 1 / 5 and less than or equal to 2 / 5.

[0017] If the ratio of L2 to L1 and the ratio of L3 to L1 are less than 1 / 5, the travel range of the first and second working members is limited, resulting in limited adjustment effect on the flexible electrical connection structure, which may not meet assembly requirements. If the ratio of L2 to L1 and the ratio of L3 to L1 are greater than 2 / 5, the travel range of the first working member is large, which will place higher requirements on the first driving member that drives the first and second working members. When the ratio of L2 to L1 and the ratio of L3 to L1 are both greater than or equal to 1 / 5 and less than or equal to 2 / 5, within this range, the first and second working members can achieve effective adjustment of the flexible electrical connection structure without placing high requirements on the first driving member, which is beneficial for cost savings.

[0018] In some optional embodiments, the first working piece includes a connected first main body and a first head, the first main body is connected to the first drive assembly, the first side surface and the second side surface are located at the first head, and the elastic coefficient of the first head is greater than or equal to the elastic coefficient of the first main body.

[0019] In this way, the first head has good elasticity, which can prevent the first working piece from causing damage to the flexible electrical connection structure.

[0020] In some optional embodiments, the first drive assembly includes a first drive member and a second drive member, the first drive member is transmission-connected to the first working member and is used to drive the first working member to move toward the first end, and the second drive member is transmission-connected to the second working member and is used to drive the second working member to move toward the second end.

[0021] In this way, the first driving member and the second driving member can independently control the first working member and the second working member, respectively, so that the assembly device can accurately adjust different parts of the flexible electrical connection structure.

[0022] In some optional embodiments, the first working unit includes a first guide structure and a second guide structure, the first guide structure is fixed relative to the first driving assembly, the second guide structure is provided on the first working piece, and the first guide structure and the second guide structure are slidably connected along the first direction.

[0023] In this way, the first and second guide structures cooperate to guide the first workpiece, ensuring that it moves precisely along a predetermined path (i.e., the first direction). This helps avoid unnecessary deviation, thereby improving the positioning accuracy of the first workpiece throughout the assembly process. Furthermore, the first and second guide structures provide additional support and guidance, making the first workpiece more stable while performing its task.

[0024] In some optional embodiments, the first working piece includes a first head, and the second working piece includes a second head. The first working unit further includes a third working piece and a fourth working piece, wherein along the first direction, the third working piece is located on a side of the first working piece facing away from the second working piece, and the fourth working piece is located on a side of the second working piece facing away from the first working piece. The third working piece is configured to secure the first end to the first circuit board assembly, and the fourth working piece is configured to secure the second end to the second circuit board assembly.

[0025] In this way, the third working piece and the fourth working piece can ensure that the first end and the second end of the flexible electrical connection structure are firmly fixed on the corresponding first circuit board assembly and the second circuit board assembly, which is conducive to improving the stability of the assembly, and can also effectively prevent the connection from loosening due to force pulling, etc., reducing the risk of functional failure, thereby enhancing the reliability of the overall equipment.

[0026] In some optional embodiments, the first working unit further includes a first adjusting member, which is connected to the third working member. When the first adjusting member moves, it can drive the third working member to move along the first direction.

[0027] In this way, the first adjusting member allows the position of the third working member to be dynamically adjusted according to actual assembly requirements, which is conducive to improving the flexibility of the assembly device. During the assembly of electronic equipment products of different specifications, the first adjusting member can be adjusted to meet specific position requirements.

[0028] In some optional embodiments, the third working member includes a third main body and a third head connected to each other, the third main body being connected to the first adjusting member, the third head being arranged on a side of the third main body facing the flexible electrical connection structure, and an elastic member being provided between the third main body and the third head.

[0029] In this way, the elastic and resilient member can provide a buffering effect and can also ensure that the pressure applied by the third head to the flexible electrical connection structure is more uniform.

[0030] In some optional embodiments, the first working piece includes a first part, a second part and a third part connected in sequence, the third part is located on the side of the first part away from the second working piece, the second part is used to connect between an end of the first part away from the flexible electrical connection structure and an end of the third part away from the flexible electrical connection structure, the first part, the second part and the third part enclose an accommodating space; the first driving member is arranged in the accommodating space.

[0031] This helps optimize the layout of the assembly device and achieve a more compact overall structural layout. This design helps save space. Furthermore, because the first driving member is located directly inside the first working member it acts on, the driving force can be transmitted more directly to the first working member, reducing energy loss and improving transmission efficiency. It also helps reduce errors caused by long-distance transmission and improves operational precision.

[0032] In some optional embodiments, the assembly device further includes a second driving assembly, and the second driving assembly is used to drive the first working unit to move in a direction toward the flexible electrical connection structure.

[0033] In this way, the second drive component can work in conjunction with the first drive component. When adjusting the redundant part of the flexible electrical connection structure, the second drive component can make the first working unit close to the target position, and then the first drive component is responsible for driving the first working unit to achieve position adjustment of the redundant part. The cooperation between the two can speed up the assembly speed and improve the assembly efficiency.

[0034] In some optional embodiments, the assembly device further includes a third drive assembly and a second working unit. The second working unit is configured to be disposed on a side of the flexible electrical connection structure facing away from the front housing. The second working unit is positioned between the first working member and the second working member along the first direction and is opposed to a middle portion of the flexible electrical connection structure connected between the first end and the second end along the second direction. The third drive assembly is configured to drive the second working unit to move toward the flexible electrical connection structure.

[0035] In this way, the third drive component can drive the second working unit to move toward the middle part of the flexible electrical connection structure to adjust the partial redundancy located in the middle part. In this way, the flexible electrical connection structure can be fully redundantly adjusted along the extension direction of the flexible electrical connection structure, which helps to avoid problems caused by excessive or insufficient local redundancy; by adjusting the redundancy of the middle part of the flexible electrical connection structure, its smooth transition and natural bending can be better guaranteed, and unnecessary bending or twisting can be reduced. This can also avoid excessive redundancy in the middle part causing the battery of the electronic device to become warped and loose.

[0036] In some optional embodiments, a storage compartment is provided on the inner surface of the front housing, the first and second circuit board assemblies are located on opposite sides of the storage compartment, and a portion of the flexible electrical connection structure is located within the storage compartment. The storage compartment has a length L1 along the direction from the first end to the second end, a dimension L4 along the first direction of the second operating unit, and a ratio of L4 to L1 is greater than or equal to 3 / 5 and less than or equal to 4 / 5.

[0037] If the ratio of L4 to L1 is less than 3 / 5, the second working unit may not work well with the first working unit. If the ratio of L4 to L1 is greater than 4 / 5, the first and second working units may interfere with each other or collide. By setting the ratio of L4 to L1 to be greater than or equal to 3 / 5 and less than or equal to 4 / 5, the first and second working units can form a good coordination effect, thus achieving effective management of the redundant parts of the flexible electrical connection structure.

[0070] See also Figure 1-Figure 2 , Figure 1A schematic structural diagram of an electronic device 200 provided in some embodiments of the present application; Figure 2 for Figure 1 An exploded view of a portion of the structure of the electronic device 200 is shown; Figure 3 for Figure 2 In this embodiment, the electronic device 200 includes a screen 30, a front housing 10, a back cover 40, a circuit board assembly 20, a battery, and the like.

[0071] It is understandable that Figure 1 and Figure 2 The following figures and the related drawings only schematically illustrate some components of the electronic device 200, and the actual shapes, sizes, positions and structures of these components are not affected by the present invention. Figure 1 and Figure 2 and the accompanying drawings below.

[0072] The electronic device 200 is in the shape of a rectangular flat plate. In some other embodiments, the shape of the electronic device 200 may also be a square flat plate, a circular flat plate, an elliptical flat plate, etc.

[0073] The front housing 10 is disposed between the screen 30 and the back cover 40 and is connected to the screen 30 and the back cover 40. The screen 30 is used to display images and videos, and a component storage space is formed between the back cover 40 and the front housing 10, for example, for accommodating electronic components such as a camera module, battery, speaker module, and vibration unit.

[0074] The circuit board assembly 20 can be set in the device accommodating space. The circuit board assembly 20 includes a first circuit board assembly 201, a second circuit board assembly 202 and a flexible electrical connection structure 203. The flexible electrical connection structure 203 is electrically connected between the first circuit board assembly 201 and the second circuit board assembly 202.

[0075] The first circuit board assembly 201 can serve as the main circuit board of the electronic device 200 and is used to integrate a control chip. The control chip may be, for example, an application processor (AP), double data rate synchronous dynamic random access memory (DDR), or universal flash storage (UFS). In some embodiments, the first circuit board assembly 201 is electrically connected to a display screen and is used to control the display screen to display images or videos.

[0076] The first circuit board assembly 201 can be a rigid circuit board, a flexible circuit board, or a combination of rigid and flexible circuit boards. The first circuit board assembly 201 can utilize FR-4 dielectric board, Rogers dielectric board, or a hybrid of FR-4 and Rogers dielectric board, among others. FR-4 is a designation for a flame-retardant material grade, and Rogers dielectric board is a high-frequency board.

[0077] The second circuit board assembly 202 can serve as a secondary circuit board of the electronic device 200 and is used to integrate electronic components such as an antenna (such as a G antenna), a radio frequency front end, a universal serial bus (USB) device, and an oscillator.

[0078] The second circuit board assembly 202 can be a rigid circuit board, a flexible circuit board, or a rigid-flexible circuit board. The second circuit board assembly 202 can be made of FR-4 dielectric board, Rogers dielectric board, or a hybrid of FR-4 and Rogers dielectric board, etc.

[0079] The second circuit board assembly 202 is electrically connected to the first circuit board assembly 201 via the flexible electrical connection structure 203 to achieve power and signal connection between the second circuit board assembly 202 and the first circuit board assembly 201, as well as data and signal transmission between the two.

[0080] The battery is located between the first circuit board assembly 201 and the second circuit board assembly 202. The battery is used to provide power to electronic components in the electronic device 200, such as the display screen, the first circuit board assembly 201, the second circuit board assembly 202, and the like.

[0081] For details, please refer to Figure 2-Figure 3 The surface of the front housing 10 facing the back cover 40 is the inner surface of the front housing 10, and the first circuit board assembly 201 and the second circuit board assembly 202 are disposed on the inner surface of the front housing 10. A storage compartment 101 is provided on the inner surface of the front housing 10. The first circuit board assembly 201 and the second circuit board assembly 202 are spaced apart and located on opposite sides of the storage compartment 101. A portion of the flexible electrical connection structure 203 is located within the storage compartment 101, with the portion of the flexible electrical connection structure 203 connected to the first circuit board assembly 201 and the portion connected to the second circuit board assembly 202 being located on opposite sides of the storage compartment 101, respectively. The battery is installed within the storage compartment 101, on the side of the flexible electrical connection structure 203 facing away from the front housing 10.

[0082] The flexible electrical connection structure 203 includes a first end 2031, a second end 2032, and a middle portion 2033 connected between the first end 2031 and the second end 2032, wherein the end of the flexible electrical connection structure 203 connected to the first circuit board assembly 201 is the first end 2031, and the end of the flexible electrical connection structure 203 connected to the second circuit board assembly 202 is the second end 2032.

[0083] In some embodiments, see Figure 3 The first circuit board assembly 201 and the first end 2031 of the flexible electrical connection structure 203 , as well as the second circuit board assembly 202 and the second end 2032 of the flexible electrical connection structure 203 , can be electrically connected via the connector 204 .

[0084] Exemplarily, the flexible electrical connection structure 203 can be a flexible printed circuit (FPC), and the connector 204 can be a board-to-board connector 204 (BTB connector 204). The flexible printed circuit is electrically connected to the first circuit board assembly 201 and the second circuit board assembly 202 through the board-to-board connector 204.

[0085] In order to ensure the connection stability between the flexible electrical connection structure 203 and the first circuit board assembly 201 and the flexible electrical connection structure 203 and the second circuit board assembly 202, the flexible electrical connection structure 203 is usually designed to have a certain amount of redundancy. It should be noted that the redundancy of the flexible electrical connection structure 203 means that when the flexible electrical connection structure 203 is connected to the first circuit board assembly 201 and the second circuit board assembly 202, the actual length of the flexible electrical connection structure 203 is greater than the distance from the first end 2031 to the second end 2032 of the flexible electrical connection structure 203, and part of the middle part 2033 between the first end 2031 and the second end 2032 is a redundant part. In other words, the actual length of the flexible electrical connection structure 203 is greater than the length of the flexible electrical connection structure 203 connected between the second end 2032 and the second end 2032 in a tensioned state. The tensioned state of the flexible electrical connection structure 203 can be seen in FIG. Figure 3 Indicated by the dotted area.

[0086] In the related art, in the process of assembling the front shell 10 and the circuit board assembly 20 of the electronic device 200 using an automated assembly device, the assembly device directly connects the first end 2031 and the second end 2032 of the flexible electrical connection structure 203 to the first circuit board assembly 201 and the second circuit board assembly 202 respectively by pressing. In this process, due to the neglect of the management effect of the redundant parts, the connection position between the first end 2031 and the first circuit board assembly 201 and the connection position between the second end 2032 and the second circuit board assembly 202 are prone to loosening or connection failure and other poor assembly problems. The redundant parts may even squeeze the battery of the electronic device 200, causing the battery to warp and loosen, thereby reducing the product qualification rate of the electronic device 200.

[0087] Based on this, an embodiment of the present application provides an assembly device that can effectively manage the redundant parts of the flexible electrical connection structure 203, so as to ensure the connection stability between the first end 2031 and the first circuit board assembly 201 and the second end 2032 and the second circuit board assembly 202 during the automated assembly process, and avoid the redundant parts squeezing the battery of the electronic device 200, causing the battery to loosen and warp, etc.

[0088] Next, the structure of the assembly device will be introduced in detail.

[0089] See also Figure 4-Figure 6 , Figure 4 A schematic structural diagram of an assembly device 100 provided in some embodiments of the present application; Figure 5 A schematic diagram of a portion of the structure of an assembly device 100 provided in some embodiments of the present application; Figure 6 for Figure 5 Another perspective diagram of a portion of the assembly device 100. The assembly device 100 may include an assembly mechanism 9, which can be used to assemble the flexible electrical connection structure 203 into the front housing 10 and connect it to the first circuit board assembly 201 and the second circuit board assembly 202.

[0090] It should be noted that Figures 4 to 6 Only partial structures of the assembly device 100 are schematically shown, and the size, shape and number of these structures are not limited to Figures 4 to 6 In some embodiments, the assembly device 100 includes Figure 5 and Figure 6 The assembly mechanism 9 shown, the assembly device 100 can also include an installation cabinet 6, a mounting frame 7, a material picking mechanism, a detection mechanism and a supporting mechanism, etc. The mounting frame 7, the material picking mechanism, the detection mechanism, the supporting mechanism and the assembly mechanism 9 are all arranged in the installation cabinet 6. The installation cabinet 6 can protect the internal structure of the electronic device 200 from dust, moisture and other pollutants during the production process.

[0091] The assembly mechanism 9, the material-picking mechanism, the detection mechanism, and the supporting mechanism can all be fixed to the mounting frame 7, which is used to provide physical support to enhance the structural stability and operational stability of the assembly device 100. The detection mechanism is used to detect the components in the material storage area to determine whether they are qualified, and can also be used to detect whether the assembled components meet the assembly requirements. The material-picking mechanism is used to transfer the qualified components to be assembled from the material storage area to the supporting mechanism, while the unqualified components will be transferred to the defective product area. The supporting mechanism can be used to carry the various components of the electronic device 200, and the assembly mechanism 9 can complete the assembly and connection operations of these components at the supporting mechanism.

[0092] In some optional embodiments, the detection mechanism may be a plurality of charge-coupled devices (CCDs), for example, by taking a picture of the device and inspecting its outline to determine whether it is a qualified product. The material picking mechanism may be a plurality of suction nozzles or grippers.

[0093] Exemplarily, the assembly process of the electronic device 200 may include the following steps: first, the device to be assembled is placed in the storage area of ​​the assembly device 100, the detection mechanism detects the component to confirm whether it is qualified, then the picking mechanism transfers the device to be assembled to the carrying mechanism through the suction nozzle, and then the assembly mechanism 9 completes the assembly operation.

[0094] Please continue reading Figure 5-Figure 6 Combined with Figure 7 , Figure 7 for Figure 5 Schematic diagram of the coordination between the partial structure of the assembly device 100 and the partial structure of the electronic device.

[0095] In some embodiments, the assembly mechanism 9 includes a first working unit 1 and a first driving assembly 2. The first working unit 1 is used to be arranged on the side of the flexible electrical connection structure 203 facing away from the front shell 10. The first working unit 1 includes a first working piece 11 and a second working piece 12 arranged along a first direction (see the direction e1 in the figure). The first direction is consistent with the direction in which the first end 2031 of the flexible electrical connection structure 203 points to the second end 2032.

[0096] It should be noted that in the description of each embodiment of the present application, "directional consistency" can include absolute consistency and approximate consistency between two directions, where the acceptable deviation range of approximate consistency is, for example, a deviation within 5°, 8° or 10° between the two directions.

[0097] The first drive assembly 2 is transmission-connected to the first working unit 1 , and is used to drive the first working piece 11 and the second working piece 12 to move in directions away from each other, so that the first working piece 11 moves toward the first end 2031 and the second working piece 12 moves toward the second end 2032 .

[0098] During operation of the assembly device 100, the first working member 11 has a first initial position and a first stop position. In the first initial position, the first working member 11 is aligned with a position in the middle portion 2033 of the flexible electrical connection structure 203. As the first drive assembly 2 drives the first working member 11 toward the first end 2031, the first working member 11 moves from the first initial position to the first stop position. As the first drive assembly 2 drives the first working member 11 toward the first end 2031, the first working member 11 can gradually adjust the partial redundancy of the flexible electrical connection structure 203 from the middle portion 2033 toward a position closer to the first end 2031.

[0099] The second working member 12 also has a second initial position and a second stop position. In the second initial position, the second working member 12 is aligned with a position in the middle portion 2033 of the flexible electrical connection structure 203. As the first drive assembly 2 drives the second working member 12 toward the second end 2032, the first working member 11 moves from the second initial position to the second stop position. As the first drive assembly 2 drives the second working member 12 toward the second end 2032, the second working member 12 can gradually adjust the partial redundancy of the flexible electrical connection structure 203 from the middle portion 2033 toward a position closer to the second end 2032.

[0100] This ensures that the flexible electrical connection structure 203 has a certain amount of redundancy at positions close to the first electrical connection component and close to the second electrical connection component, so as to avoid excessive tension of the first end 2031 or the second end 2032 during the assembly process of the electronic device 200 due to the asymmetric distribution of the redundancy of the flexible electrical connection structure 203, resulting in unstable connection with the first circuit board assembly 201 or the second circuit board assembly 202, and avoid the problem of loosening of the connection position, which is conducive to improving the problem of poor assembly and improving the connection quality between the circuit board assemblies 20.

[0101] In addition, adjusting the redundant part of the flexible electrical connection structure 203 toward a position close to the first end 2031 and the second end 2032 can also avoid excessive redundancy in the middle part 2033 of the flexible electrical connection structure 203, thereby avoiding excessive bending of the flexible electrical connection structure 203 during the subsequent assembly process of the electronic device 200, and avoiding excessive redundant parts squeezing the battery, causing it to warp and loosen, thereby reducing the resulting product failure rate.

[0102] Of course, the first driving assembly 2 can also drive the first working piece 11 from the first stop position back to the first initial position, and the first driving assembly can also drive the second working piece 12 from the second stop position back to the second initial position.

[0103] Please continue reading Figure 5-Figure 7 In some embodiments, the assembly mechanism 9 may further include a second drive assembly 3 in addition to the above-mentioned first working unit 1 and the first drive assembly 2. The second drive assembly 3 is transmission-connected to the first working unit 1. The second drive assembly 3 is used to drive the first working unit 1 to move in a direction toward the flexible electrical connection structure 203, so as to ensure that the distance between the first working unit 1 and the flexible electrical connection structure 203 and the front shell 10 meets the assembly requirements, so that the first working piece 11 and the second working piece 12 adjust the position of the redundant part of the flexible electrical connection structure 203.

[0104] Of course, the second drive assembly 3 can also drive the first working unit 1 to move away from the flexible electrical connection structure 203. When the first working member 11 moves to the first stop position and the second working member 12 moves to the second stop position, the second drive assembly 3 can drive the first working unit 1 to move away from the flexible electrical connection structure 203, so that the first drive assembly 2 drives the first working member 11 to move away from the first end 2031 and the second working member 12 to move away from the second end 2032. For the convenience of the following description, the direction of the first working unit 1 toward and away from the flexible electrical connection structure 203 is defined as the second direction (see direction e2 in the figure).

[0105] In this way, the second drive component 3 can work in conjunction with the first drive component 2. When adjusting the redundant part of the flexible electrical connection structure 203, the second drive component 3 can make the first working unit 1 close to the target position, and then the first drive component 2 is responsible for driving the first working unit 1 to achieve the position adjustment of the redundant part. The cooperation between the two can speed up the assembly speed and improve the assembly efficiency.

[0106] In some other embodiments, the assembly device 100 may also be provided with no second drive assembly 3, and the supporting mechanism may be provided as a mechanism that can be raised and lowered along the second direction toward the first working unit 1. This can also ensure that the distance between the first working unit 1 and the flexible electrical connection structure 203 and the front housing 10 meets the assembly requirements. This application does not impose specific limitations on this. The embodiments of the present application are further described based on the provision of the second drive assembly 3 in the assembly device 100 to drive the first working unit 1 to move toward the flexible electrical connection structure 203. This should not be considered a special limitation on the present application.

[0107] Please continue reading Figure 5 and Figure 7In some embodiments, the first drive assembly 2 includes a first drive member 21 and a second drive member 22. The first drive member 21 is transmission-connected to the first working member 11 and is used to drive the first working member 11 to move toward the first end 2031. The second drive member 22 is transmission-connected to the second working member 12 and is used to drive the second working member 12 to move toward the second end 2032.

[0108] In some optional embodiments, the first driving member 21 and the second driving member 22 can both be cylinders. For the convenience of description, the cylinder serving as the first driving member 21 is referred to as the first cylinder, and the cylinder serving as the second driving member 22 is referred to as the second cylinder.

[0109] Please continue reading Figure 5 and Figure 7 In other embodiments, the first working unit 1 further includes a support structure 8, and the first drive assembly 2, the first working piece 11, and the second working piece 12 are all arranged on the support structure 8 to improve the installation stability and working reliability of the first drive assembly 2 and the first working unit 1.

[0110] The cylinder bodies of the first and second cylinders are both fixedly connected to the support structure 8. The first working member 11 is connected to the piston rod of the first cylinder, and the second working member 12 is connected to the piston of the second cylinder. During the assembly process of the electronic device 200, the piston rod of the first cylinder drives the first working member 11 toward the first end 2031, and the piston rod of the second cylinder drives the second working member 12 toward the second end 2032.

[0111] In this way, the first driving member 21 and the second driving member 22 can independently control the first working member 11 and the second working member 12 , respectively, so that the assembly device 100 can accurately adjust different parts of the flexible electrical connection structure 203 .

[0112] In some optional embodiments, the second drive component 3 can also be a cylinder. The cylinder serving as the second drive component 3 is referred to as a third cylinder. The cylinder body of the third cylinder is fixedly connected to the mounting frame 7, and the piston rod of the third cylinder is connected to the support structure 8, so that the second drive component 3 can simultaneously drive the first working piece 11, the second working piece 12 and the first drive component 2 of the first working unit 1 toward or away from the flexible electrical connection structure 203.

[0113] The following mainly introduces the internal structure of the first working part 11 and its connection relationship with the support structure 8 and the first driving part 21. The internal structure of the second working part and its connection relationship with the support structure 8 and the second driving part 22 can be the same as the internal structure of the first working part 11 and its connection relationship with the support structure 8 and the first driving part 21, and this application will not go into details about this.

[0114] In other embodiments, the internal structure of the second actuating member and its connection relationship with the support structure 8 and the second driving member 22 may also be different from the internal structure of the first working member 11 and its connection relationship with the support structure 8 and the first driving member 21. This application is illustratively described as the internal structure of the second actuating member and its connection relationship with the support structure 8 and the second driving member 22 being the same as the internal structure of the first working member 11 and its connection relationship with the support structure 8 and the first driving member 21.

[0115] See also Figure 7 and Figure 8 , Figure 8 for Figure 5 Enlarged view of point A in the middle. In some embodiments, the first working member 11 includes a first main body 113 and a first head 114 connected to each other. The first main body 113 is connected to the first driving member 21. The first driving member 21 drives the first main body 113 to move, thereby driving the first head 114 to move toward the first end 2031. The first head 114 can adjust the position of the partially redundant portion of the flexible electrical connection structure 203 from the middle portion 2033 to a position closer to the first end 2031.

[0116] In some optional embodiments, the first head 114 may gradually change the position of the partial redundancy as the first head 114 moves toward the first end 2031 by contacting and applying pressure to the surface of the flexible electrical connection structure 203 facing away from the front shell 10 .

[0117] In some optional embodiments, the first main body 113 and the first head 114 are detachably connected, which facilitates replacement and maintenance of the first head 114 .

[0118] In some optional embodiments, the first main body portion 113 and the first head portion 114 may also be formed as an integrally formed part, which helps to simplify the processing technology.

[0119] In some embodiments, the elastic coefficient of the first head portion 114 is greater than or equal to the elastic coefficient of the first body portion 113. Optionally, the first head portion 114 is made of an elastic material, and the first body portion 113 is made of a rigid material. For example, the first head portion 114 is made of an elastic material such as silicone or rubber, and the first body portion 113 is made of a metal material. Alternatively, both the first head portion 114 and the first body portion 113 are made of an elastic material, for example, both the first head portion 114 and the first body portion 113 are made of an elastic material such as silicone.

[0120] In this way, the first head portion 114 has good elasticity, which can prevent the first working member 11 from causing damage to the flexible electrical connection structure 203 .

[0121] For details, please refer to Figure 7and Figure 8 In some embodiments, the first main body portion 113 includes a first part 1131, a second part 1132 and a third part 1133 connected in sequence, the third part 1133 is located on the side of the first part 1131 away from the second working piece 12, and the second part 1132 is used to connect between an end of the first part 1131 away from the flexible electrical connection structure 203 and an end of the third part 1133 away from the flexible electrical connection structure 203.

[0122] The first head 114 is connected to one end of the first portion 1131 facing the flexible electrical connection structure 203 . Thus, the first head 114 is farther away from the first end 2031 of the flexible electrical connection structure 203 , which helps to increase the movement space of the first head 114 .

[0123] In some embodiments, the first portion 1131, the second portion 1132, and the third portion 1133 define an accommodating space 1134, and the first driving member 21 is disposed in the accommodating space 1134. Exemplarily, the first driving member 21 is connected to a side of the third portion 1133 facing the first portion 1131. For example, the first driving member 21 is a first cylinder, and a piston rod of the first cylinder is connected to a side of the third portion 1133 facing the first portion 1131.

[0124] This helps optimize the layout of the assembly device 100 and achieve a more compact overall structural layout. This design helps save space. In addition, because the first driving member 21 is directly located within the first working member 11 on which it acts, the driving force can be more directly transmitted to the first working member 11, reducing energy loss and improving transmission efficiency. It also helps reduce errors caused by long-distance transmission and improves operational accuracy.

[0125] Please continue reading Figure 8 In some optional embodiments, the first working piece 11 may include a third adjusting piece 19, which is connected to the first head 114 and can adjust the distance between the first head 114 and the flexible electrical connection structure 203 along the second direction. This is conducive to further accurately controlling the adjustment effect of the first working piece 11 on the flexible electrical connection structure 203.

[0126] Please continue reading Figure 8In some embodiments, the end of the first working member 11 facing the flexible electrical connection structure 203 is the third end 111, and the end of the first working member 11 facing away from the flexible electrical connection structure 203 is the fourth end 112. The third end 111 includes a first side surface 1111 and a second side surface 1112. The first side surface 1111 faces the second working member 12, and the second side surface 1112 faces away from the second working member 12. The distance from the first side surface 1111 to the second side surface 1112 gradually decreases along the direction from the fourth end 112 to the third end 111. The direction from the third end 111 to the third end 111 is consistent with the second direction.

[0127] In this way, without increasing the overall size of the device, the first working member 11 is provided with more room for movement, thereby expanding the travel range of the first working member 11 along the first direction. This helps increase the adjustment range when the first working member 11 adjusts the redundant portion of the flexible electrical connection structure 203. Furthermore, this helps optimize the mating relationship between the first working member 11 and the flexible electrical connection structure 203, for example, by optimizing the contact angle and pressure.

[0128] Please continue reading Figure 8 In some embodiments, the first side surface 1111 and the second side surface 1112 are located on the first head portion 114. This can further increase the movement space of the first head portion 114, thereby improving the adjustment effect of the first working member 11 on the redundant portion of the flexible electrical connection structure 203.

[0129] Please continue reading Figure 8 In some embodiments, along the direction from the fourth end 112 to the third end 111, the first side surface 1111 extends obliquely away from the second working member 12. This can reduce interference between the first working member 11 and surrounding components, thereby improving the operational flexibility of the first working member 11.

[0130] On this basis, in other embodiments, along the direction from the fourth end 112 to the third end 111, the second side surface 1112 may also be inclined toward the direction close to the second work piece 12; or the second side surface 1112 may be formed as a plane extending along the direction from the fourth end 112 to the third end 111.

[0131] Please continue reading Figure 7 and Figure 8 In some embodiments, the second side surface 1112 is adapted to fit with the inner side surface of the accommodating compartment 101 adjacent to the first circuit board assembly 201 .

[0132] Exemplarily, the inner side surface of the accommodating chamber 101 adjacent to the first circuit board assembly 201 is formed as a plane, and the second side surface 1112 can be formed as a plane adapted to the inner side surface of the accommodating chamber 101 adjacent to the first circuit board assembly 201 .

[0133] Exemplarily, the inner side surface of the accommodating chamber 101 adjacent to the first circuit board assembly 201 is formed as a curved surface, and the second side surface 1112 can be formed as a curved surface adapted to the inner side surface of the accommodating chamber 101 adjacent to the first circuit board assembly 201 .

[0134] In the process of the first driving member 21 driving the first working member 11 to move toward the first end 2031, when the first working member 11 moves to the position where the second side surface 1112 contacts the inner side surface of the accommodating chamber 101 adjacent to the first circuit board assembly 201, the first working member 11 reaches the first stop position and the first driving member 21 stops driving.

[0135] In this way, during the movement of the first working piece 11 toward the first end 2031, the assembly device 100 can control the position of the first working piece 11 by means of the matching relationship between the second side surface 1112 and the inner side surface of the accommodating bin 101 adapted thereto, so as to achieve accurate control of the travel range of the first working piece 11, thereby facilitating the control of the adjustment range of the redundant part of the flexible electrical connection structure 203.

[0136] In some optional embodiments, a cylinder with a corresponding stroke can be configured as the first driving member 21 based on the travel distance from the first initial position of the first working member 11 to the first stop position where the second side 1112 contacts the inner side of the accommodating chamber 101 adjacent to the first circuit board assembly 201.

[0137] In some embodiments, the first head portion 114 further comprises a curved surface 1113 on a side facing away from the second working member 12. The curved surface 1113 is connected to the end of the second side surface 1112 facing the fourth end 112. The end of the curved surface 1113 connected to the second side surface 1112 is closer to the third end 111 than the end of the curved surface 1113 facing away from the second side surface 1112, and the curved surface 1113 is formed to be concave in a direction away from the third end 111. Thus, when the first head portion 114 moves to a position where it mates with the inner side surface of the accommodating chamber 101, the curved surface 1113 can be used to avoid interference with or damage to components near the accommodating chamber 101.

[0138] See also Figure 9-10 , Figure 9 for Figure 5 A front view of a portion of the structure of the assembly device 100; Figure 10 for Figure 9Enlarged view of point B in the middle. In some embodiments, the first working unit 1 further includes a first guide structure 13 and a second guide structure 14, wherein the first guide structure 13 is fixed relative to the first driving member 21, and the second guide structure 14 is provided on the first working member 11, and the first guide structure 13 and the second guide structure 14 are slidably connected along a first direction.

[0139] The first guide structure 13 is fixedly connected to the support structure 8. That is, the first working member 11 is indirectly connected to the support structure 8 via the first guide structure 13 and the second guide structure 14. The first guide structure 13 and the first drive assembly 2 are fixed relative to each other. Thus, when the first drive assembly 2 drives the first working member 11 to move, the first working member 11 can drive the second guide structure 14 to slide relative to the first guide structure 13, so that the first working member 11 can accurately move toward the first end 2031.

[0140] In this way, the first guide structure 13 and the second guide structure 14 cooperate to guide the first working piece 11, ensuring that the first working piece 11 moves precisely along a predetermined path. This helps avoid unnecessary deviation, thereby improving the positioning accuracy of the first working piece 11 throughout the assembly process. In addition, the first guide structure 13 and the second guide structure 14 provide additional support and guidance, making the first working piece 11 more stable when performing its task.

[0141] Please continue reading Figure 9-10 Combined with Figure 7 In some optional embodiments, the support structure 8 includes a first support plate 81 and a first support block 82 provided on the first support plate 81. The extension direction of the first support plate 81 is the second direction. For the convenience of subsequent description, the thickness direction of the first support plate 81 is defined as the third direction (see the direction e3 in the figure). The first direction, the second direction and the third direction intersect with each other.

[0142] The first support block 82 is configured to be disposed on a side of the first support plate 81 facing the front housing 10 along the thickness direction thereof, and the first support block 82 is located within the accommodating space 1134 of the first working member 11. Along the second direction, the first support block 82 and the second portion 1132 of the first working member 11 are disposed opposite and spaced apart from each other.

[0143] Please continue reading Figure 10In some optional embodiments, along the second direction, the first guide structure 13 is provided on the end surface of the first support block 82 facing the second portion 1132, and the second guide structure 14 is provided on the surface of the second portion 1132 facing the first support block 82. Exemplarily, the first guide structure 13 is a slide rail, and the second guide structure 14 is a slider, and the slider is slidably connected to the slide rail. Specifically, the slide rail can be a riding slide rail, having a first slide groove and a second slide groove arranged opposite to each other, and the slider has a first sliding portion and a second sliding portion arranged opposite to each other, and the first sliding portion and the second sliding portion are respectively accommodated in the first slide groove and the second slide groove.

[0144] Of course, in other optional embodiments, the slide rail may also be a slot-type slide rail.

[0145] In some optional embodiments, the first guide structure 13 is detachably connected to the first support block 82 , and the second guide structure 14 is detachably connected to the second portion 1132 of the first working member 11 .

[0146] Please continue reading Figure 9-10 In some optional embodiments, the first driving member 21 is fixedly connected to the first support plate 81, and along the third direction, the first driving member 21 and the first support block 82 are located on the same side. Along the second direction, the first support block 82 and the first driving member 21 are staggered. This can reduce the space required for the first support block 82 and the first driving member 21 in the first direction. For example, the first driving member 21 is located along the second direction on a side of the first support block 82 away from the second portion 1132.

[0147] Of course, in other embodiments, the first working unit 1 may also include a third guide structure and a fourth guide structure. The relationship between the third guide structure and the fourth guide structure and the second working piece 12 and the guiding principle thereof are the same as the relationship between the first guide structure 13 and the second guide structure 14 and the first working piece 11 and the guiding principle thereof, and will not be elaborated on in the embodiments of the present application.

[0148] See also Figure 7-10 In some embodiments, the first working unit 1 further includes a third working piece 15 . Along the first direction, the third working piece 15 is located on the side of the first head 114 facing away from the second working piece 12 . The third working piece 15 is used to fix the first end 2031 to the first circuit board assembly 201 .

[0149] The second working member 12 includes a second main body and a second head portion disposed on the second main body. The first working unit 1 also includes a fourth working member 16 located on a side of the second head portion facing away from the first working member 11 along the first direction. The fourth working member 16 is used to secure the second end 2032 to the second circuit board assembly 202.

[0150] It should be noted that in the embodiment of the present application, “fixed on” can be understood as ensuring a stable and reliable electrical and mechanical connection between the first end 2031 of the flexible electrical connection structure 203 and the first circuit board assembly 201 or the second end 2032 and the second circuit board assembly 202 in some way.

[0151] In some optional embodiments, during the process of the second driving component 3 driving the first working unit 1 to move toward the flexible electrical connection structure 203, the third working piece 15 fixes the first end 2031 to the first circuit board assembly 201 by pressing, and the fourth working piece 16 fixes the second end 2032 to the second circuit board assembly 202 by pressing; or, the third working piece 15 fixes the first end 2031 to the first circuit board assembly 201 by clamping, and the fourth working piece 16 fixes the second end 2032 to the second circuit board assembly 202 by clamping.

[0152] Exemplarily, the first end 2031 of the flexible electrical connection structure 203 is connected to the first circuit board assembly 201 via the board-to-board connector 204, and the second end 2032 is connected to the second circuit board assembly 202 via the board-to-board connector 204. While the second drive assembly 3 is driving the first working unit 1 toward the flexible electrical connection structure 203, the third working member 15 and the fourth working member 16 press on the board-to-board connector 204 to secure the first end 2031 to the first circuit board assembly 201 and the second end 2032 to the second circuit board assembly 202. The pressure applied by the third working member 15 and the fourth working member 16 to the board-to-board connector 204 should generally be less than 65N to avoid unnecessary damage.

[0153] In this way, the third working piece 15 and the fourth working piece 16 can ensure that the first end 2031 and the second end 2032 of the flexible electrical connection structure 203 are firmly fixed to the corresponding first circuit board assembly 201 and the second circuit board assembly 202, which is conducive to improving the stability of the assembly and effectively preventing the connection from loosening due to force or pulling, thereby reducing the risk of functional failure and thus enhancing the reliability of the entire device. For example, this can prevent the first end 2031 and the second end 2032 from being pulled when the first working piece 11 and the second working piece 12 are adjusting the redundant portion of the flexible electrical connection structure 203, thereby preventing the connection from loosening due to pulling.

[0154] In some optional embodiments, the third working piece 15 is arranged in the accommodating space 1134 of the first working piece 11, and the third working piece 15 can be movably connected to the first support block 82, so that the third working piece 15 can make full use of the space inside the accommodating space 1134, so that the first working unit 1 has a compact structure, and this makes it easier for the distance between the third working piece 15 and the first head 114 to meet the production requirements of the electronic device 200.

[0155] Please continue reading Figure 10 In some embodiments, the first working unit 1 further includes a first adjusting member 17 , which is connected to the third working member 15 . When the first adjusting member 17 moves, it can drive the third working member 15 to move along the first direction.

[0156] Specifically, the first adjusting member 17 is connected between the first support block 82 and the third working member 15. When the first adjusting member 17 moves, it can drive the third working member 15 to move relative to the first support block 82 along the first direction. Of course, the first adjusting member 17 may not be connected to the first support block 82, and the third working member 15 may be movably connected to the first support block 82 through other connecting members. This can achieve that under the driving action of the first adjusting member 17, the third working member 15 is movable relative to the first working member 11, and the spacing between the first working member 11 and the third working member 15 along the first direction is adjustable. The embodiment of the present application is described on the basis that the third working member 15 is movably connected to the first support block 82 via the first adjusting member 17, but this does not constitute a specific limitation of the present application.

[0157] Exemplarily, the first adjusting member 17 is an adjusting screw. When the first adjusting member 17 rotates, it can drive the third working member 15 to move along the first direction toward or away from the first working member 11 .

[0158] In this way, the first adjusting member 17 allows the position of the third working member 15 along the first direction to be dynamically adjusted according to actual assembly requirements, thereby improving the flexibility of the assembly device 100. During the assembly of electronic devices 200 of different specifications, the first adjusting member 17 can be adjusted to meet specific position requirements.

[0159] Please continue reading Figure 10 In some embodiments, the third working member 15 includes a connected third main body portion 151 and a third head portion 152, the third main body portion 151 is connected to the first adjusting member 17, the third main body portion 151 is connected to the first support block 82 through the first adjusting member 17, and the third head portion 152 is located on the side of the first support portion facing away from the first guide structure 13.

[0160] In some optional embodiments, the third head 152 is detachably connected to the third body 151. Exemplarily, the third head 152 is provided with a first connection hole, the third body 151 is provided with a second connection hole, and the connector is passed through the first connection hole and connected to the second connection hole.

[0161] The third head portion 152 is arranged on a side of the third main portion 151 facing the flexible electrical connection structure 203. An elastic member 153 is provided between the third main portion 151 and the third head portion 152. For example, the elastic member 153 is sleeved on the outer periphery of the connector.

[0162] In this way, the elastic member 153 can provide a buffering effect and can also ensure that the pressure applied by the third head 152 to the flexible electrical connection structure 203 is more uniform.

[0163] In some optional embodiments, along the second direction, there is a height difference between the end surface of the third head portion 152 facing the flexible electrical connection structure 203 and the end surface of the first head portion 114 facing the flexible electrical connection structure 203. The height difference may be determined based on the depth of the accommodating compartment 101 of the electronic device 200 and the height of the connecting component between the first end 2031 and the first circuit board assembly 201. For example, if the first end 2031 and the first circuit board assembly 201 are connected via a board-to-board connector, the height difference may need to meet the depth requirements of the accommodating compartment 101 and the height requirements of the board-to-board connector.

[0164] Please continue reading Figure 10 In some optional embodiments, the third working piece 15 may further include a second adjusting piece 18, which is connected between the third main body 151 and the third head 152. When the third working piece 15 moves, it can drive the third head 152 to move in a direction close to the flexible electrical connection structure 203, so that the distance between the third head 152 and the flexible electrical connection structure 203 along the second direction can be adjusted.

[0165] The internal structure of the fourth working piece 16 and its connection relationship with the second working piece 12 are the same as the internal structure of the third working piece 15 and its connection relationship with the first working piece 11 , and will not be described in detail in this application.

[0166] Please return to Figure 5-Figure 7 In some embodiments, the assembly device 100 further includes a third drive assembly 5 and a second working unit 4. The second working unit 4 is configured to be disposed on a side of the flexible electrical connection structure 203 facing away from the front housing 10. Along the first direction, the second working unit 4 is located between the first working piece 11 and the second working piece 12, and is opposite to the middle portion 2033 of the flexible electrical connection structure 203, which is connected between the first end 2031 and the second end 2032, along the second direction. The third drive assembly 5 is transmission-connected to the second working unit 4 and is configured to drive the second working unit 4 toward the flexible electrical connection structure 203. The third drive assembly 5 can drive the second working unit 4 toward the middle portion 2033 of the flexible electrical connection structure 203 to adjust the partial redundancy located in the middle portion 2033.

[0167] In some optional embodiments, the second working unit 4 adjusts the position of the partial redundancy located in the middle portion 2033 by pressing the middle portion 2033 of the flexible electrical connection structure 203 .

[0168] In some optional embodiments, the third drive component 5 can be a cylinder, and the cylinder serving as the third drive component 5 is called a fourth cylinder. The cylinder body of the fourth cylinder is fixedly connected to the mounting bracket 7, and the piston rod of the fourth cylinder is connected to the second working unit 4 to drive the second working unit 4 to move toward or away from the flexible electrical connection structure 203.

[0169] In this way, through the cooperation of the first working unit 1 and the second working unit 4, the flexible electrical connection structure 203 can be fully redundantly adjusted along the extension direction of the flexible electrical connection structure 203, which helps to avoid problems caused by excessive or insufficient local redundancy; by adjusting the redundancy of the middle part 2033 of the flexible electrical connection structure 203, its smooth transition and natural bending can be better guaranteed, and unnecessary bending or twisting can be reduced. This can also avoid the excessive redundancy of the middle part 2033 causing the battery of the electronic device 200 to become warped and loose.

[0170] Of course, the third driving assembly 5 can also be used to drive the second working unit 4 to move in a direction away from the flexible electrical connection structure 203 .

[0171] In order to ensure that the first working unit 1 effectively adjusts the redundant part of the flexible electrical connection structure 203 and avoids interference between the first working unit 1 and other components during movement, it is necessary to control the travel distance of the first working piece 11 toward the first end 2031 and the travel distance of the second working piece 12 toward the second end 2032.

[0172] Please continue reading Figure 7 In some embodiments, the dimension of the accommodating chamber 101 along the direction from the first end 2031 to the second end 2032 is L1. The travel of the first working member 11 toward the first end 2031 is L2. That is, the distance between the first initial position and the first stop position of the first working member 11 is L2. The travel of the second working member 12 toward the second end 2032 is L3. That is, the distance between the second initial position and the second stop position of the second working member 12 is L3. The ratio of L2 to L1 and the ratio of L3 to L1 are both greater than or equal to 1 / 5 and less than or equal to 2 / 5.

[0173] If the ratio of L2 to L1 and the ratio of L3 to L1 are less than 1 / 5, the travel range of the first working member 11 and the second working member 12 is limited, resulting in limited adjustment effect on the flexible electrical connection structure 203, and may not meet assembly requirements. If the ratio of L2 to L1 and the ratio of L3 to L1 are greater than 2 / 5, the travel range of the first working member 11 is large, which will place higher requirements on the first driving member 21 that drives the first working member 11 and the second working member 12. When the ratio of L2 to L1 and the ratio of L3 to L1 are both greater than or equal to 1 / 5 and less than or equal to 2 / 5, within this range, the first working member 11 and the second working member 12 can achieve effective adjustment of the flexible electrical connection structure 203 without placing high requirements on the first driving member 21, which is conducive to cost savings.

[0174] In order to achieve effective coordination between the first working unit 1 and the second working unit 4 and avoid interference or collision between the two, in some embodiments, the dimension of the second working unit 4 along the first direction is L4, and the ratio of L4 to L1 is greater than or equal to 3 / 5 and less than or equal to 4 / 5.

[0175] If the ratio of L4 to L1 is less than 3 / 5, the second working unit 4 and the first working unit 1 may not work well together. If the ratio of L4 to L1 is greater than 4 / 5, the first working unit 1 and the second working unit 4 may interfere with each other or collide with each other. By setting the ratio of L4 to L1 to be greater than or equal to 3 / 5 and less than or equal to 4 / 5, the first working unit 1 and the second working unit 4 can form a good cooperation effect, thereby achieving effective management of the redundant parts of the flexible electrical connection structure 203.
