Description

Technical Field

[0001] This invention relates to the field of smart wearable device manufacturing technology, and in particular to an assembly tooling and assembly method. Background Technology

[0002] The assembly of temple shells and hinge components is a critical step in the manufacturing process of eyeglasses, smart wearable devices, and other products. Its assembly quality directly impacts the product's stability and user experience. Currently, the assembly of these products still largely relies on manual operation to connect and assemble the temple shells and hinge components. However, manual assembly has significant limitations: firstly, it is inefficient, and the assembly pace is greatly affected by human factors, making it difficult to meet the efficiency requirements of large-scale production; secondly, the precision of manual assembly depends on the operator's experience and skill, and human error can easily lead to inaccurate alignment of the temple shells and hinge components, thus affecting the product's assembly consistency and overall quality, and increasing subsequent rework costs. Summary of the Invention

[0003] The main objective of this invention is to provide an assembly fixture and assembly method, which aims to solve the problems of low efficiency and poor precision in manual assembly.

[0004] To achieve the above objectives, the present invention provides an assembly fixture, comprising:

[0005] Mounting base, the mounting base being used for movement on the line body; The first assembly includes a first fixed base and a first movable base disposed on the first fixed base. The first fixed base is located on the mounting base. One side of the first movable base has a first contour groove adapted to the shape of the first component. The first movable base is movable relative to the first fixed base along the assembly direction to have a first position and a second position. The second assembly is disposed on the mounting base, and a second contour groove adapted to the shape of the second component is provided on the side of the second assembly away from the mounting base. The assembly direction is set at an angle to the horizontal direction; when the first movable seat is in the first position, the assembly end of the first component located in the first contour groove is away from the assembly end of the second component located in the second contour groove; when the first movable seat is in the second position, the assembly end of the first component located in the first contour groove and the assembly end of the second component located in the second contour groove are connected along the assembly direction.

[0006] In one embodiment, the first fixing base includes a positioning base and a fixing bracket, wherein the positioning base is disposed on the mounting base; and the fixing bracket is disposed on the side of the positioning base opposite to the mounting base. The first assembly also includes a first guide structure, which includes a first slide rail and a first slider. One of the first slide rail and the first slider is located on the first movable seat, and the other is located on the fixed bracket.

[0007] In one embodiment, the first assembly further includes a first elastic reset member, which is connected between the fixed bracket and the first movable seat, for driving the first movable seat to reset from the second position to the first position.

[0008] In one embodiment, the first movable seat has a positioning groove at one end near the mounting base; the assembly fixture further includes a clamp, which is disposed on the positioning base; the clamp has a positioning protrusion at one end near the first movable seat; when the first movable seat is in the second position, the positioning protrusion engages with the positioning groove to limit the position of the first movable seat relative to the first fixed seat; and / or The first fixed seat further includes a limiting block, which is disposed at the end of the fixed bracket away from the positioning base; when the first movable seat is in the first position, the limiting block abuts against the end of the first movable seat away from the positioning base to limit the position of the first movable seat relative to the first fixed seat.

[0009] In one embodiment, the first assembly further includes two grippers disposed on the first movable seat, the two grippers being spaced apart along the width direction of the first component, and a clamping space for pressing the first component is formed between the two grippers; The gripper has a gripping state and a releasing state. In the gripping state, the gripper abuts against the side of the first component away from the bottom wall of the first contour groove to press the first component into the first contour groove. In the releasing state, the gripper disengages from the first component.

[0010] In one embodiment, the second assembly includes: A second fixing seat is disposed on the mounting base; the second fixing seat has a first groove segment on the side facing the first movable seat; and The second movable seat is disposed between the first fixed seat and the second fixed seat, and the second movable seat is movable relative to the fixed seat along the assembly direction; the second movable seat has a second groove segment on the side facing the second fixed seat, and the first groove segment and the second groove segment together form the second contour groove; During the process of the first movable seat moving from the first position to the second movable seat, the first movable seat can abut against the second movable seat and drive the second movable seat to move.

[0011] In one embodiment, the second fixed seat has a clearance groove that communicates with the first slot segment on the side opposite to the second movable seat; The second assembly also includes a clamping push rod and a damping structure. The clamping push rod is movably mounted on the second fixed seat via the damping structure. The clamping push rod has a clamped state and an open state. In the clamped state, at least a portion of the clamping push rod extends from the clearance groove into the first groove section under the action of the damping force provided by the damping structure to abut against the second component, thereby locking the second component in the second contour groove. In the open state, the clamping push rod overcomes the damping force to move away from the second component, thereby releasing the second component from the second contour groove.

[0012] In one embodiment, the clamping push rod is hinged to the second fixed seat, and the damping structure includes a second elastic reset member. One end of the second elastic reset member is fixedly connected to the inner wall of the second fixed seat, and the other end is fixedly connected to the outer wall of the clamping push rod. The second elastic reset member is always in a pre-tightened state, providing the clamping push rod with the damping force toward the second contour groove.

[0013] In one embodiment, the second assembly further includes a third resilient reset member connected between the mounting base and the second movable base; and / or The second assembly also includes a second guide structure, which includes a second slide rail and a second slider. One of the second slide rail and the second slider is located on the second movable seat, and the other is located on the second fixed seat.

[0014] The present invention also provides an assembly method for assembling a first component and a second component using the assembly fixtures described above, the assembly method comprising: The assembly tool is placed on the production line, so that the first movable seat is initially in the first position; The first component is positioned within the first contour groove of the first movable seat, and the second component is positioned within the second contour groove of the second assembly. Drive the first movable seat to slide relative to the first fixed seat along the assembly direction, thereby moving the first component toward the side closer to the second component; Until the first movable seat moves to the second position, the assembly end of the first component and the assembly end of the second component are aligned along the assembly direction.

[0015] The assembly fixture provided by this invention solves the problems of low efficiency, inaccurate docking positions, poor assembly consistency, and high rework costs when manually assembling the first and second components by employing a mounting base that rotates on a line, a first assembly component containing a first fixed base and a first movable base that can move along the assembly direction (with a first contouring groove for the first component), and a second assembly component with a second contouring groove for the second component. Specifically, during assembly, the first component is first placed into the first contouring groove of the first movable base for positioning, and the second component is placed into the second contouring groove of the second assembly component for positioning. At this time, the first movable base is in a first position, and the assembly ends of the two components are far apart. Then, the first movable base is driven to move relative to the first fixed base along an assembly direction that forms an angle with the horizontal direction to a second position, so that the assembly ends of the first and second components dock along the assembly direction to complete the assembly. Moreover, the mounting base can drive the entire assembly structure to rotate on a line to achieve continuous operation. In this way, the first and second contour grooves are adapted to the shapes of the first and second components respectively, realizing their positioning. Together with the directional movement of the first movable seat along the fixed assembly direction, it avoids manual operation deviations, ensures the accuracy of the docking position, improves product assembly consistency and overall quality, reduces subsequent rework costs, and reduces reliance on the experience and proficiency of operators, thereby improving production stability.

[0023] This invention provides an assembly fixture 100.

[0024] Please refer to Figure 1 and Figure 2 In one embodiment, the assembly fixture 100 includes: Mounting base 1, which is used for circulation on the line; The first assembly 2 includes a first fixed base 21 and a first movable base 22 disposed on the first fixed base 21. The first fixed base 21 is disposed on the mounting base 1. One side of the first movable base 22 is provided with a first contour groove 221 adapted to the shape of the first component 200. The first movable base 22 is movable relative to the first fixed base 21 along the assembly direction to have a first position and a second position. The second assembly 3 is located on the mounting base 1. The second assembly 3 has a second contour groove 321 on the side opposite to the mounting base 1 that matches the shape of the second component 300. The assembly direction is set at an angle to the horizontal direction; when the first movable seat 22 is in the first position, the assembly end of the first component 200 located in the first contour groove 221 is far away from the assembly end of the second component 300 located in the second contour groove 321; when the first movable seat 22 is in the second position, the assembly end of the first component 200 located in the first contour groove 221 and the assembly end of the second component 300 located in the second contour groove 321 are connected along the assembly direction.

[0025] It should be noted that the basic load-bearing structure of the assembly fixture 100 is the mounting base 1. This mounting base 1 can be made of hard alloy or high-strength engineering plastic to balance structural stability and lightweight requirements. Its shape can be adapted to the conveyor structure of the production line. The core function of the mounting base 1 is that it can be directly mounted on the conveyor track or conveyor device of the automated production line. It can be equipped with additional positioning structures, enabling it to complete continuous flow operations with the line, thus smoothly connecting multiple processes such as loading, assembly, and unloading on the production line. This breaks the rhythm limitations of manual assembly mode and provides solid structural support for large-scale continuous production.

[0026] The first assembly 2 consists of a first fixed seat 21 and a first movable seat 22. The first fixed seat 21 can be made of a rigid metal material, and its overall structure must have sufficient strength to be stably installed on the surface of the mounting base 1. The first fixed seat 21 and the mounting base 1 can be fixed by welding or bolt connection to ensure that there is no positional displacement during assembly. The first movable seat 22 is movably connected to the first fixed seat 21 and can be made of engineering plastic or alloy material to reduce wear during movement while ensuring structural strength. The surface of the first movable seat 22 facing the second assembly 3 is machined with a first contour groove 221. The internal shape of the first contour groove 221 is adapted to the shape of the first component 200, which can form a covering positioning of the first component 200 and prevent the first component 200 from shaking or shifting during assembly. The first movable seat 22 can reciprocate relative to the first fixed seat 21 along a preset assembly direction, thereby having a first position and a second position that can be switched between each other. Its movement can be achieved by its own drive mechanism or an external drive mechanism. Common drive mechanisms can be motors or cylinders to meet the power requirements of different production scenarios.

[0027] The second assembly 3 is directly installed on the surface of the mounting base 1. Its installation position must correspond to the position of the first assembly 2 to ensure that the first movable base 22 can smoothly move the first component 200 to and engage with the second component 300 during the movement process. The second assembly 3 can be made of the same rigid metal material as the first fixed base 21 to ensure structural stability during assembly and prevent deformation due to external forces. The side of its surface facing away from the mounting base 1 is machined with a second contour groove 321. The internal shape of the second contour groove 321 is adapted to the shape of the second component 300, which can form a firm and secure positioning for the second component 300, so that the second component 300 always maintains a fixed posture during the assembly process.

[0028] The assembly direction is a key design feature of this assembly fixture 100 to achieve docking. This assembly direction is set at an angle to the horizontal direction. The angle can be adjusted according to the docking angle requirements of the first component 200 and the second component 300 or other processing requirements (such as the dispensing process). The angle setting allows the assembly end of the first component 200 and the assembly end of the second component 300 to form a closer contact state during the docking process, avoiding stress concentration or assembly interference caused by horizontal assembly. When the first movable seat 22 is in the first position, the assembly end of the first component 200 located in the first contour groove 221 and the assembly end of the second component 300 located in the second contour groove 321 are in a state of being far apart from each other. At this time, it is convenient for operators or automated equipment to perform the loading operation of the first component 200 and the second component 300, or to reserve dispensing space in the dispensing process. When the first movable seat 22 is in the second position, the assembly end of the first component 200 located in the first contour groove 221 can be connected with the assembly end of the second component 300 located in the second contour groove 321 along the preset assembly direction, thereby completing the assembly operation of the first component 200 and the second component 300.

[0029] The assembly fixture 100 provided by the present invention, by employing a mounting base 1 that flows on the line, a first assembly part 2 including a first fixed base 21 and a first movable base 22 that can move along the assembly direction (with a first contour groove 221 adapted to the first component 200), and a second assembly part 3 with a second contour groove 321 adapted to the second component 300, can solve the problems of low efficiency, inaccurate docking position, poor assembly consistency and high rework cost when manually assembling the first component 200 and the second component 300. Specifically, during assembly, the first component 200 is first positioned by placing it into the first contour groove 221 of the first movable seat 22, and the second component 300 is positioned by placing it into the second contour groove 321 of the second assembly 3. At this time, the first movable seat 22 is in the first position, and the assembly ends of the two components are far apart. Then, the first movable seat 22 is driven to move relative to the first fixed seat 21 along an assembly direction at an angle to the horizontal to the second position, so that the assembly ends of the first component 200 and the second component 300 are aligned along the assembly direction to complete the assembly. The mounting seat 1 can drive the entire assembly structure to rotate on the line to achieve continuous operation. In this way, the first contour groove 221 and the second contour groove 321 are adapted to the shapes of the first component 200 and the second component 300, respectively, to achieve their positioning. Combined with the directional movement of the first movable seat 22 along the fixed assembly direction, manual operation deviations are avoided, the accuracy of the alignment position is guaranteed, the consistency of product assembly and overall quality can be improved, subsequent rework costs can be reduced, and the dependence on the experience and skill of operators can be reduced, thus improving production stability.

[0030] Furthermore, considering the assembly requirements of the temple shell and hinge assembly in the background technology and the tooling structure design of the solution, in this embodiment, the first component 200 can be set as the temple shell, and the second component 300 can be set as the hinge assembly. That is, the first contouring groove 221 in the solution can adapt to the outer contour of the temple shell to achieve positioning, the second contouring groove 321 can match the outer features of the hinge assembly to complete fixation, and the first movable seat 22 moves along the assembly direction at an angle to the horizontal direction, which can drive the temple shell and the hinge assembly to dock.

[0031] Please see Figure 1 , Figure 2 and Figure 3 In one embodiment, the first fixed base 21 includes a positioning base 211 and a fixing bracket 212. The positioning base 211 is disposed on the mounting base 1; the fixing bracket 212 is disposed on the side of the positioning base 211 opposite to the mounting base 1. The first assembly 2 also includes a first guide structure 23, which includes a first slide rail 231 and a first slider 232. One of the first slide rail 231 and the first slider 232 is located on the first movable seat 22, and the other is located on the fixed bracket 212.

[0032] It should be noted that, in one embodiment, the first fixed base 21 is specifically composed of a positioning base 211 and a fixing bracket 212. The positioning base 211 can be made of rigid metal and has a plate-like structure, which can stably fit the surface of the mounting base 1. It is fixedly connected to the mounting base 1 by bolts or welding to ensure that there will be no loosening or displacement during the assembly process. The fixing bracket 212 is located on the side of the positioning base 211 away from the mounting base 1. It can be made of high-strength alloy material and has a frame structure, which has sufficient support strength to provide a stable bearing foundation for the movement of the first movable base 22, while reserving suitable installation space for the installation of the first guide structure 23.

[0033] The first guide structure 23 is composed of a first slide rail 231 and a first slider 232 that cooperate with each other. The first slide rail 231 can be made of wear-resistant alloy material, and its overall shape is long and narrow. The surface is polished to reduce frictional resistance during sliding. The first slider 232 can be made of engineering plastic or wear-resistant metal material. Its groove is adapted to the shape of the first slide rail 231, and it can form a tight sliding fit with the first slide rail 231. Through the sliding fit, the direction of movement of the first movable seat 22 relative to the first fixed seat 21 can be limited, so that the first movable seat 22 can only reciprocate along the preset assembly direction.

[0034] In this embodiment, the first fixed base 21 is divided into a combination structure of a positioning base 211 and a fixed bracket 212. The installation position and angle of the fixed bracket 212 can be flexibly adjusted according to actual assembly requirements, improving the adaptability and versatility of the first assembly part 2. The first guide structure 23 further limits the movement trajectory of the first movable base 22 through the cooperation of the slide rail and the slider, avoiding the first movable base 22 from deviating or getting stuck during the movement, ensuring that the first component 200 can smoothly approach the second component 300 along the preset assembly direction, significantly improving the docking accuracy between the first component 200 and the second component 300, while reducing the wear of the first movable base 22 during the movement, extending the service life of the assembly tooling 100, thereby improving the stability and continuity of the entire assembly process and better meeting the needs of large-scale production.

[0035] Please see Figure 1 and Figure 2 In one embodiment, the first assembly 2 further includes a first elastic reset member 24, which is connected between the fixed bracket 212 and the first movable seat 22 and is used to drive the first movable seat 22 to reset from the second position to the first position.

[0036] It should be noted that the first elastic reset component 24 can be made of a material with good elastic recovery performance, such as a spring or an elastic rubber block. Its specific structural form can be adapted to the installation space between the fixed bracket 212 and the first movable seat 22. If a spring is selected, a spiral structure can be adopted; if an elastic rubber block is selected, a block structure can be adopted, which can stably connect between the fixed bracket 212 and the first movable seat 22. The first elastic reset member 24 can be connected by hook snap or slot fitting. One end is connected to the side of the fixed bracket 212 facing the first movable seat 22, and the other end is connected to the side of the first movable seat 22 facing the fixed bracket 212. In its natural state, the first elastic reset member 24 can maintain its initial extended state and drive the first movable seat 22 to the first position. When the first movable seat 22 moves to the second position along the assembly direction under the drive of external force, the first elastic reset member 24 will undergo elastic deformation and accumulate elastic potential energy. After the external force disappears, the first elastic reset member 24 releases the accumulated elastic potential energy, which can drive the first movable seat 22 to automatically reset from the second position to the first position without the need for an additional reverse drive structure.

[0037] In this embodiment, the addition of the first elastic reset member 24 enables the automatic reset function of the first movable seat 22. After completing one assembly operation of the first component 200 and the second component 300, the first movable seat 22 can automatically return to the initial first position without manual or additional drive mechanism intervention. This facilitates the operation of the operator or automated equipment to perform the next set of material loading or dispensing operations of the first component 200 and the second component 300, effectively shortening the process interval time and improving the overall assembly efficiency.

[0038] Please see Figure 2 and Figure 3 In one embodiment, the first movable seat 22 has a positioning groove 222 at one end near the mounting base 1; the assembly fixture 100 also includes a clamp 4, which is disposed on the positioning base 211; the clamp 4 has a positioning protrusion 41 at one end near the first movable seat 22; when the first movable seat 22 is in the second position, the positioning protrusion 41 engages with the positioning groove 222 to limit the position of the first movable seat 22 relative to the first fixed seat 21.

[0039] It should be noted that the first movable seat 22 has a positioning groove 222 at one end near the mounting seat 1. This positioning groove 222 can be an arc-shaped groove or a rectangular groove, etc., to fit the positioning protrusion 41. Correspondingly, the first fixed seat 21 is also provided with a clamp 4. The clamp 4 is made of rigid metal and has sufficient structural strength to be stably installed on the positioning base 211. The installation position corresponds to the positioning groove 222 of the first movable seat 22, ensuring that the two can be aligned. The clamp 4 has a positioning protrusion 41 integrally formed or fixed by bolts at one end near the first movable seat 22. The shape of the positioning protrusion 41 matches the internal shape of the positioning groove 222, forming a conformal snap-fit ​​structure. When the first movable seat 22 moves to the second position (i.e., the assembly position where the first component 200 and the second component 300 are docked) under the drive of external force, the clamp 4 will cause the positioning protrusion 41 to be embedded in the positioning groove 222 in the static or driving state, forming a stable snap-fit ​​engagement, thereby limiting the position of the first movable seat 22 relative to the first fixed seat 21 and preventing the first movable seat 22 from being accidentally displaced during the assembly process.

[0040] In this embodiment, the positioning groove 222 and the positioning protrusion 41 are engaged to reliably position the first movable seat 22 at the critical position (second position) of the assembly operation, ensuring that the first component 200 and the second component 300 maintain a stable relative position after docking, effectively avoiding assembly deviation caused by the shaking of the first movable seat 22, and further improving the assembly accuracy and product assembly consistency.

[0041] Please see Figure 1 and Figure 2In one embodiment, the first fixed seat 21 further includes a limiting block 213, which is disposed at the end of the fixed bracket 212 away from the positioning base 211. When the first movable seat 22 is in the first position, the limiting block 213 abuts against the end of the first movable seat 22 away from the positioning base 211 to limit the position of the first movable seat 22 relative to the first fixed seat 21.

[0042] It should be noted that the limiting block 213 can be made of a metal material with high hardness and wear resistance. It can be fixed to the end of the fixed bracket 212 away from the positioning base 211 by bolt connection or welding. Its installation position corresponds to the movement trajectory of the first movable seat 22, ensuring that the position of the first movable seat 22 is limited. The surface of the limiting block 213 facing the first movable seat 22 is smoothed and polished to reduce friction loss when in contact with the first movable seat 22. At the same time, a layer of wear-resistant rubber pad can be added to the contact surface to avoid damage to the components caused by rigid contact. When the first movable seat 22 is reset to the first position under the drive of the first elastic reset member 24, the end of the first movable seat 22 away from the positioning base 211 will abut against the contact surface of the limiting block 213. At this time, the limiting block 213 can prevent the first movable seat 22 from moving further away from the second assembly 3 through its own rigid structure, thereby limiting the position of the first movable seat 22 relative to the first fixed seat 21, so that the first movable seat 22 is stably stopped in the initial position that is convenient for loading.

[0043] In this embodiment, the addition of the limiting block 213 can reliably limit the first position of the first movable seat 22, avoiding excessive reset of the first movable seat 22 due to excessive elastic potential energy when the first elastic reset member 24 drives the reset, ensuring that the first movable seat 22 is in a uniform initial position after each reset, and improving the consistency and convenience of the feeding operation.

[0044] Please see Figure 1 In one embodiment, the first assembly 2 further includes two grippers 25 disposed on the first movable seat 22. The two grippers 25 are spaced apart along the width direction of the first component 200, and a clamping space for pressing the first component 200 is formed between the two grippers 25. The gripper 25 has a gripping state and a releasing state. In the gripping state, the gripper 25 abuts against the side of the first component 200 away from the bottom wall of the first contour groove 221 to press the first component 200 into the first contour groove 221. In the releasing state, the gripper 25 disengages from the first component 200.

[0045] It should be noted that the grippers 25 are made of a metal material with both rigidity and toughness, which ensures structural stability during clamping, prevents deformation, and reduces pressure or scratches on the surface of the first component 200. The two grippers 25 are spaced apart along the width of the first component 200, with the spacing matching the width of the first component 200. They enclose a clamping space for pressing the first component 200. The contour of this clamping space matches the shape of the corresponding area of ​​the first component 200, ensuring a close fit during pressing. The grippers 25 have switchable clamping and releasing states. This switching can be achieved through elastic drive, a small drive component, or a detachable structure. For example, an elastic element can be placed between the two grippers 25, allowing them to remain in the releasing state under normal conditions and switch to the clamping state under external force, or vice versa. When the gripper 25 is in the gripping state, the end of the gripper 25 will abut against the side of the first component 200 away from the bottom wall of the first contour groove 221. By applying pressure towards the bottom wall of the groove, the first component 200 is firmly pressed into the first contour groove 221, forming a fixed structure for groove positioning and reverse pressing. When the gripper 25 is in the released state, the gripper 25 will actively detach from the surface of the first component 200 and no longer apply pressure. At this time, the picking and putting operation of the first component 200 can be completed smoothly.

[0046] In this embodiment, the first component 200 is directionally pressed by two grippers 25 arranged along the width direction of the first component 200. Compared with the traditional side clamping structure, the first component 200 can be fixed more directly at the preset positioning position of the first contour groove 221, avoiding the first component 200 from moving along the groove depth direction during the assembly process, and further improving the positioning accuracy.

[0047] Please see Figure 1 and Figure 2 In one embodiment, the second assembly 3 includes: The second fixing seat 31 is disposed on the mounting seat 1; the side of the second fixing seat 31 facing the first movable seat 22 is provided with a first groove section; and The second movable seat 32 is located between the first fixed seat 21 and the second fixed seat 31. The second movable seat 32 can move relative to the fixed seat in the assembly direction. The second movable seat 32 has a second groove segment on the side facing the second fixed seat 31. The first groove segment and the second groove segment together form a second contour groove 321. Specifically, when the first movable seat 22 moves from the first position to the second movable seat 32, the first movable seat 22 can abut against the second movable seat 32 and drive the second movable seat 32 to move.

[0048] It should be noted that the second fixed seat 31 can be made of rigid metal material, possessing sufficient structural stability. It is firmly installed on the surface of the mounting base 1 by means of bolt connection or other methods, and its installation position corresponds to the movement trajectory of the first movable seat 22, ensuring smooth subsequent cooperation with the first movable seat 22 and the second movable seat 32. The second fixed seat 31 has a first groove segment on the side facing the first movable seat 22. The shape of the first groove segment is adapted to the shape of the corresponding side of the second component 300, providing basic support for the positioning of the second component 300.

[0049] The second movable seat 32 is disposed between the first fixed seat 21 and the second fixed seat 31. It can be made of wear-resistant alloy material or high-strength engineering plastic to meet the wear requirements during reciprocating movement. It can reciprocate relative to the second fixed seat 31 along a preset assembly direction. The movable engagement method can adopt a guide structure such as slide rail and slider engagement. The second movable seat 32 has a second groove segment on the side facing the second fixed seat 31. The shape of the second groove segment is adapted to the shape of the other side of the second component 300. When the second movable seat 32 is in the initial position, its second groove segment can align with the first groove segment of the second fixed seat 31 to jointly form a complete second contour groove 321, which can realize the covering and positioning of the second component 300.

[0050] During the assembly process, when the first movable seat 22 moves from the first position to the second position under the drive of external force, the end of the first movable seat 22 near the second assembly 3 will first abut against the second movable seat 32. As the first movable seat 22 continues to move, it will synchronously drive the second movable seat 32 to move along the assembly direction towards the second fixed seat 31, ensuring that the first component 200 and the second component 300 can form a smooth fit and advance during the docking process.

[0051] In this embodiment, the second assembly 3 is designed as a combination of a second fixed seat 31 and a second movable seat 32. The two work together to form an adjustable second contour groove 321. This not only positions the second component 300 but also adapts to the positioning requirements of second components 300 of different specifications, improving the versatility and adaptability of the second assembly 3. Simultaneously, the movement of the first movable seat 22 synchronously drives the movement of the second movable seat 32, creating a linked propulsion process between the first component 200 and the second component 300. This avoids misalignment that might occur with unilateral driving, further improving the stability and precision of the docking process.

[0052] Please see Figure 1 , Figure 2 and Figure 3 In one embodiment, the second fixed seat 31 has a clearance groove 311 that communicates with the first groove segment on the side opposite to the second movable seat 32; The second assembly 3 also includes a clamping push rod 33 and a damping structure. The clamping push rod 33 is movably mounted on the second fixed seat 31 via the damping structure. The clamping push rod 33 has a clamped state and an unclamped state. In the clamped state, at least part of the structure of the clamping push rod 33 extends from the clearance groove 311 into the first groove section under the action of the damping force provided by the damping structure to abut against the second component 300, thereby locking the second component 300 in the second contour groove 321. In the unclamped state, the clamping push rod 33 overcomes the damping force to move away from the second component 300, thereby releasing the second component 300 from the second contour groove 321.

[0053] It should be noted that the clearance groove 311 is connected to the first groove section and has an overall elongated structure, providing ample clearance space for the movement of the clamping push rod 33. The second assembly 3 is also equipped with a clamping push rod 33 and a damping structure. The clamping push rod 33 is made of rigid metal and has sufficient structural strength to withstand damping force and contact pressure without deformation. Its end can be designed as a contoured surface to improve the fit when in contact with the second component 300. The damping structure can be a damping spring or damping sleeve, etc., with stable damping performance. It is assembled inside the second fixed base 31 by embedding or bolt fixing. The clamping push rod 33 is movably mounted on the second fixed base 31 through this damping structure. The damping structure can provide a continuous and stable damping force for the clamping push rod 33, realizing the smooth movement and state maintenance of the clamping push rod 33. The clamping push rod 33 has a switchable clamping state and an open state. When it is in the clamping state, under the damping force provided by the damping structure, part of the clamping push rod 33 extends from the clearance groove 311 into the first groove section and abuts against the side wall of the second component 300. Through continuous abutment force, the second component 300 is firmly locked in the second contour groove 321 formed by the first groove section and the second groove section. When it is in the open state, the external force drives the clamping push rod 33 to overcome the damping force of the damping structure and move away from the second component 300, so that the part that extends into the first groove section completely retracts into the clearance groove 311, releasing the abutment lock on the second component 300, so that the second component 300 can be picked up and put down smoothly.

[0054] In this embodiment, the clearance groove 311 provides movement space for the clamping push rod 33. Combined with the damping structure and the synergistic effect of the clamping push rod 33, reliable locking and convenient unlocking of the second component 300 within the second contour groove 321 are achieved. This effectively prevents displacement or shaking of the second component 300 during dispensing or assembly, further improving the positioning stability of the second component 300 and ensuring the degree of docking with the first component 200. Simultaneously, unlocking only requires overcoming the damping force, making the operation convenient and responsive, and adaptable to automated assembly processes.

[0055] In one embodiment, the clamping push rod 33 is hinged to the second fixed seat 31. The damping structure includes a second elastic reset member. One end of the second elastic reset member is fixedly connected to the inner wall of the second fixed seat 31, and the other end is fixedly connected to the outer wall of the clamping push rod 33. The second elastic reset member is always in a pre-tightened state, providing a damping force to the clamping push rod 33 toward the second contour groove 321.

[0056] It should be noted that the hinge point between the clamping push rod 33 and the second fixed seat 31 can be a pin structure. The pin is made of wear-resistant alloy material, which can ensure the smoothness and structural stability of the clamping push rod 33 during rotation, and avoid problems such as excessive clearance or jamming during long-term rotation. The second elastic reset component can be a cylindrical helical spring or a spiral spring, and its material is preferably high-strength spring steel to meet the fatigue resistance requirements under continuous preload, and avoid failure due to long-term elastic deformation. The preload force of the second elastic reset component can be adapted and adjusted according to the material and shape of the second component 300, which can ensure reliable contact and locking of the second component 300, and prevent deformation of the second component 300 due to excessive preload force, which would affect the subsequent assembly accuracy. At the same time, the connection position between the second elastic reset component and the inner wall of the second fixed seat 31 and the outer wall of the clamping push rod 33 should be provided with a limiting groove to ensure the firmness of the connection, prevent the reset component from falling off or displacing during the rotation of the clamping push rod 33, and ensure stable output of damping force.

[0057] In this embodiment, the hinged structure, in conjunction with the pre-tightened second elastic reset member, makes the movement trajectory of the clamping push rod 33 more controllable, reduces friction during rotation, and improves the response speed of clamping and unlocking actions. The pre-tightened second elastic reset member continuously provides stable damping force, maintaining the clamping state without additional drive components, further simplifying the tooling structure and reducing equipment failure rate and maintenance costs. Furthermore, the adjustable pre-tightening force design allows this structure to adapt to different specifications of the second component 300, improving the versatility of the second assembly 3, while preventing damage to the second component 300 due to excessive clamping force, thus ensuring product quality.

[0058] Please see Figure 3 In one embodiment, the second mounting component 3 further includes a third elastic reset member 34, which is connected between the mounting base 1 and the second movable base 32.

[0059] It should be noted that the third elastic reset component 34 can be made of components with good elastic recovery performance, such as cylindrical helical springs or elastic rubber columns, and is preferably made of high-strength spring steel to withstand fatigue wear during reciprocating expansion and contraction, thus extending the service life of the component. One end of the third elastic reset component 34 can be fixed to the surface of the mounting base 1 facing the second movable base 32 by welding or snap-fitting, and the other end is fixed to the surface of the second movable base 32 facing away from the second fixed base 31. Its installation position must match the movement trajectory of the second movable base 32 to ensure that the elastic reset force can act on the second movable base 32 along the assembly direction. In its natural state, the third elastic reset member 34 remains in its initial extended state, driving the second movable seat 32 to its initial position where it surrounds the second fixed seat 31 to form a complete second contour groove 321, so as to position the second component 300 for loading. When the first movable seat 22 moves to the second position and abuts against the second movable seat 32, driving it to move closer to the second fixed seat 31, the third elastic reset member 34 will undergo elastic deformation and accumulate elastic potential energy as the second movable seat 32 moves. After the first component 200 and the second component 300 complete their docking and assembly, when the first movable seat 22 resets after the external force is removed, the third elastic reset member 34 will release the accumulated elastic potential energy, driving the second movable seat 32 to automatically reset to its initial position, preparing for the loading and assembly of the next set of second components 300.

[0060] In this embodiment, the addition of the third elastic reset member 34 enables the automatic reset function of the second movable seat 32. The reset action can be completed without the need for an additional drive mechanism, which further simplifies the overall structure of the tooling and reduces the manufacturing cost and failure probability of the equipment.

[0061] Please see Figure 3 In one embodiment, the second assembly 3 further includes a second guide structure 35, which includes a second slide rail 351 and a second slider 352. One of the second slide rail 351 and the second slider 352 is disposed on the second movable seat 32, and the other is disposed on the second fixed seat 31.

[0062] It should be noted that the second assembly 3 also includes a second guide structure 35, which consists of a second slide rail 351 and a second slider 352 that are mutually adapted to each other, used to limit the direction of movement of the second movable seat 32 relative to the second fixed seat 31. The second slide rail 351 can be made of wear-resistant alloy material and has an overall elongated structure; the second slider 352 can be made of wear-resistant metal or high-strength engineering plastic material that matches the second slide rail 351, and its groove is adapted to the shape of the second slide rail 351 to form a tight sliding fit, avoiding any wobbling or gaps. In terms of installation and adaptation, either the second slide rail 351 or the second slider 352 is fixedly mounted on the side surface of the second movable seat 32 facing the second fixed seat 31, and the other component is correspondingly fixedly mounted on the side surface of the second fixed seat 31 facing the second movable seat 32. The installation direction of both is consistent with the preset assembly direction, ensuring that the second movable seat 32 can only reciprocate along the assembly direction without deviation or jamming.

[0063] In addition, limiting protrusions can be provided at both ends of the second slide rail 351, and limiting flanges can be provided at the corresponding positions of the second slider 352. The cooperation of the two can limit the maximum travel of the second movable seat 32, preventing it from colliding with other components due to excessive movement, or from disengaging from the second fixed seat 31. At the same time, the second slide rail 351 and the second movable seat 32, and the second slider 352 and the second fixed seat 31 can be fixed by bolts or embedding to ensure the connection is firm, prevent components from loosening or shifting during sliding, and ensure the stability of the guiding accuracy.

[0064] In this embodiment, the second guide structure 35, through the cooperation of the slide rail and the slider, can strictly limit the movement trajectory of the second movable seat 32, ensuring that it always moves smoothly along the assembly direction, avoiding deformation of the second contour groove 321 enclosed by the first groove segment and the second groove segment due to movement offset, thereby ensuring the positioning accuracy of the second component 300 and improving the accuracy of docking with the first component 200.

[0065] Please see Figure 4 Corresponding to the assembly fixture 100 described above, the present invention also provides an assembly method for assembling a first component 200 and a second component 300 using the assembly fixture 100 described above. This assembly method includes: S10. Place the assembly fixture 100 on the line, so that the first movable seat 22 is initially in the first position; S20. The first component 200 is limited in the first contour groove 221 of the first movable seat 22, and the second component 300 is limited in the second contour groove 321 of the second assembly 3. S30, drive the first movable seat 22 to slide relative to the first fixed seat 21 along the assembly direction, causing the first component 200 to move towards the side closer to the second component 300; S40, until the first movable seat 22 moves to the second position, the assembly end of the first component 200 and the assembly end of the second component 300 are aligned along the assembly direction.
