Description

Technical Field

[0001] This disclosure relates to the field of tooling, and more specifically, to an assembly apparatus and method for assembling components such as optical lenses into their mounting holes. Background Technology

[0002] When assembling components that require embedded assembly (such as high-precision, fragile components like optical lenses), for example, when assembling an optical lens into a coaxial mounting hole in a lens holder, several key challenges arise: (1) stringent precision requirements: to ensure component precision, the gap between the edge of the component and the sidewall of the mounting hole must be very small, even only a few micrometers, requiring extremely high installation accuracy; (2) risk of fragility: the fragility of components means that even slight pressure during installation can cause damage; (3) depth control: when multiple components need to be inserted into a single mounting hole, the required installation depth is often significant. Therefore, maintaining absolute precision throughout the installation process is crucial to preventing components from jamming.

[0003] Existing assembly methods mainly include manual assembly, temperature difference assembly, and lubrication assembly. However, these existing assembly methods all have some drawbacks. For example, manual assembly is difficult to achieve the required precision, has a high error and damage rate, and is inefficient; temperature difference assembly requires precise temperature control, is complex to operate, is not suitable for all materials, and has safety issues; lubrication assembly can lead to lubricant contamination of parts.

[0004] Therefore, there is an urgent need in this field for a technical solution that can improve the assembly efficiency and accuracy of components while ensuring the safety of components during assembly. Summary of the Invention

[0005] To address the problems in the prior art, this disclosure proposes an improved assembly apparatus for assembling components requiring embedded assembly (e.g., high-precision, fragile components such as optical lenses) into mounting holes in a bracket. The mounting holes extend along an axis from a top opening at the top of the bracket to a bottom opening at the bottom of the bracket. The assembly apparatus includes: a vibration platform configured to vibrate horizontally; a clamp mounted on the vibration platform, configured to secure the bracket to the vibration platform such that the axis of the mounting hole is oriented vertically and the top opening is upwardly open; a cushioning pad placed on the component; and a counterweight placed on the cushioning pad, the cushioning pad and the counterweight configured to enter the mounting hole along with the component.

[0006] According to an alternative embodiment of this disclosure, the clamp defines a central opening on its inner side for receiving the bracket and has a plurality of threaded holes extending from its outer side to the central opening, each threaded hole being configured to engage with the screw of a positioning bolt and allow the screw to pass through.

[0007] According to an alternative embodiment of this disclosure, the assembly device further includes a support pad placed in the central opening of the clamp, the support pad being configured to abut against the bottom of the bracket.

[0008] According to one alternative embodiment of this disclosure, the support pad is configured to cover the bottom opening of the bracket.

[0010] According to one alternative embodiment of this disclosure, the bottom of the counterweight abuts against the upper surface of the cushioning pad.

[0011] According to an alternative embodiment of this disclosure, the bottom of the counterweight is inserted into the central hole of the buffer pad, and the buffer pad has a step formed in the central hole for abutting against the bottom of the counterweight.

[0012] According to an alternative embodiment of this disclosure, the portion of the cushioning pad located around the counterweight is pressed tightly against the counterweight.

[0013] According to an alternative embodiment of this disclosure, the cushioning pad has an inner wall defining the central hole and an outer wall opposite to the inner wall, the outer wall being tapered and sloping toward the inner wall as it approaches the lower surface of the cushioning pad.

[0014] According to an optional embodiment of this disclosure, the assembly device further includes a buffer washer, which is fitted onto the side wall of the counterweight so that the buffer washer surrounds the counterweight.

[0015] According to an alternative embodiment of this disclosure, the counterweight has an annular groove recessed from its sidewall, a portion of the buffer washer is received in the annular groove, and other portions of the buffer washer protrude from the annular groove.

[0016] Similarly, to address the problems in the prior art described above, this disclosure also proposes an improved assembly method, which uses the assembly device described in this disclosure to assemble components into mounting holes in a bracket, wherein the assembly method includes the following steps:

[0017] S100: Install the fixture of the assembly device onto the vibration platform of the assembly device;

[0018] S200: Fix the bracket to the clamp such that the axis of the mounting hole is oriented vertically and the top opening of the bracket is open upward;

[0019] S300: Insert a portion of the component into the top opening, place the cushioning pad of the assembly device on the component, and place the counterweight of the assembly device on the cushioning pad;

[0020] S400: Start the vibration platform so that the buffer pad and the counterweight enter the mounting hole along with the component under the action of gravity; and

[0022] According to an optional embodiment of this disclosure, the assembly method further includes the following steps between steps S100 and S200: placing the support pad in the central opening of the clamp, and inserting the bracket into the central opening of the clamp, such that the support pad abuts against the bottom of the bracket and covers the bottom opening of the bracket.

[0023] According to an optional embodiment of this disclosure, the assembly method further includes the following steps after step S500: placing the support pad in the central opening of the fixture, and inserting the bracket into the central opening of the fixture such that the support pad abuts against the bottom of the bracket and covers the bottom opening of the bracket; and repeating steps S200-S500 to assemble another component into the mounting hole of the bracket.

[0030] Further features and advantages of this disclosure will become more apparent from the following description with reference to the accompanying drawings. Exemplary embodiments of this disclosure are shown in the drawings, and the drawings are not necessarily drawn to scale. However, this disclosure can be implemented in many different forms and should not be construed as necessarily limited to the exemplary embodiments shown herein. Rather, these exemplary embodiments are provided merely to illustrate this disclosure and to convey the spirit and essence of this disclosure to those skilled in the art.

[0031] This disclosure aims to provide an improved assembly apparatus that, due to its novel design, enables the rapid and precise assembly of components (e.g., optical lenses) into equally precise mounting holes. This significantly improves assembly efficiency and, compared to manual assembly, significantly reduces component damage rates and assembly errors. Compared to lubrication-based assembly, it significantly reduces the risk of component contamination, and compared to temperature-differential assembly, it significantly reduces the risk of stress damage caused by temperature differences. Therefore, the assembly apparatus according to this disclosure not only significantly improves assembly efficiency and accuracy but also significantly reduces the risk of component damage during assembly, thus ensuring component safety.

[0032] Various alternative, but non-limiting, embodiments of the assembly apparatus according to this disclosure are described in detail below with reference to the accompanying drawings.

[0033] refer to Figure 1 A schematic perspective view of an assembly apparatus according to one embodiment of the present disclosure is shown, and for clarity, Figure 1 Some components are shown in partially cut-out form. For example... Figure 1 As shown, the assembly device 100 is used to assemble a component 200 (e.g., a high-precision, fragile component such as an optical lens) into a mounting hole 310 of a bracket 300. The mounting hole 310 extends along axis XX' to the top 320 of the bracket 300 to form a top opening 311 on the top 320 through which the component 200 can enter and exit the mounting hole 310. Figure 1In the illustrated embodiment, the mounting hole 310 also extends along axis XX' to the bottom 330 of the bracket 300 to form a bottom opening 312 on the bottom 330. That is, the mounting hole 310 extends through the bracket 300 along axis XX', with its two ends leading to the top 320 and bottom 330 of the bracket 300, respectively. Specifically, the diameter of the mounting hole 310 decreases near the bottom opening 312, thereby forming a step 313 within the mounting hole 310 for supporting the member 200. In particular, when the member 200 is an optical lens, light can enter the mounting hole 310 from the top opening 311 and exit from the bottom opening 312 after passing through the optical lens 200, where the optical lens 200 processes the light as it passes through. However, to ensure accurate light processing, the optical axis of the optical lens 200 needs to be highly coincident with the axis XX' of the mounting hole 310. Therefore, both the optical lens 200 and the mounting hole 310 require high-precision machining, and their diameters are very close, even differing by only a few micrometers. Of course, if component 200 is another component, in order to ensure the accuracy of the effect, the diameter of component 200 also needs to be very close to the diameter of the mounting hole 310, which obviously makes the assembly of component 200 difficult.

[0034] In order to smoothly and accurately assemble component 200 into the mounting hole 310 of bracket 300, such as Figure 1 As shown, the assembly apparatus 100 includes a vibration platform 110 and a clamp 120 mounted on the vibration platform. The vibration platform 110 is configured to vibrate in the horizontal direction (e.g., vibrating in the horizontal direction at a frequency of more than 500 Hz and an amplitude of less than 0.5 mm), while the clamp 120 is configured to fix a bracket 300 on the vibration platform 110 such that the bracket 300 can vibrate in the horizontal direction together with the vibration platform 110, and the clamp 120 positions the bracket 300 such that the top opening 311 is open upward and the axis XX' is oriented in the vertical direction. Additionally, the assembly device 100 includes a cushioning pad 130 and a counterweight 140. The cushioning pad 130 may be made of a cushioning material such as foam, silicone, or rubber and is configured to be placed on the component 200. The counterweight 140 is generally cylindrical and is configured to be placed on the cushioning pad 130, so that the counterweight 140 can exert downward pressure on the component 200 through the cushioning pad 130 due to its own weight. The cushioning pad 130 spacees the counterweight 140 from the component 200. Furthermore, the cushioning pad 130 and the counterweight 140, like the component 200, are adapted to enter the mounting hole 310 of the bracket 300. In other words, the cushioning pad 130 and the counterweight 140 are adapted to enter the mounting hole 310 of the bracket 300 together with the component 200.

[0035] During the assembly of component 200, firstly, clamp 120 is mounted on vibration platform 110, and bracket 300 is fixed to clamp 120 such that the axis XX' of mounting hole 310 is oriented vertically and top opening 311 is open upwards; then, component 200 is partially inserted into top opening 311 such that a portion of component 200 is located inside mounting hole 310, while the other portion is located outside mounting hole 310 (in other words, component 200 partially protrudes from mounting hole 310), and buffer pad 130 is placed on component 200 and counterweight 140 is placed on buffer pad 130; then, vibration platform 110 is started. After vibration platform 110 is started, clamp 120 mounted on vibration platform 110 and bracket 300 fixed to clamp 120 will move along with the vibration platform 110. The vibration platform 110 vibrates horizontally together, but the component 200 cannot vibrate synchronously with the support 300 due to its own inertia. This causes the edge of the component 200 to be unable to maintain contact with the side wall of the mounting hole 310, thereby reducing the friction between the edge of the component 200 and the side wall of the mounting hole 310. This allows the component 200 to automatically move downward into the mounting hole 310 under its own weight and the pressure applied by the counterweight 140. The buffer pad 130 and the counterweight 140 will move downward into the mounting hole 310 along with the component 200, thereby continuously applying downward pressure to the component 200 so that the component 200 continues to move downward. Finally, after the component 200 reaches the specified depth in the mounting hole 310, the vibration platform 110 is turned off and the buffer pad 130 and the counterweight 140 are removed.

[0036] Therefore, under the above configuration, the assembly apparatus 100 according to this disclosure can smoothly and accurately assemble the component 200 into the designated depth in the mounting hole 310 of the bracket 300. Furthermore, since the buffer pad 130 prevents the counterweight 140 from directly contacting the component 200 and buffers the pressure applied by the counterweight 140, the safety of the component 200 during assembly is also guaranteed. In summary, the assembly apparatus 100 according to this disclosure can assemble the component 200 with high efficiency and accuracy while ensuring the safety of the component 200 during assembly.

[0037] In particular, such as Figure 1As shown, the clamp 120 is generally annular in shape and defines a central opening 121 on its inner side for receiving the bracket 300. Additionally, the clamp 120 has a plurality of smooth holes 122 extending vertically through it and a plurality of threaded holes 123 extending horizontally from the outside of the clamp 120 to the central opening 121. Each smooth hole 122 allows fasteners (not shown) such as screws, bolts, or rivets to pass through, enabling multiple fasteners to mount the clamp 120 onto the vibration platform 110. Each threaded hole 123 engages with and allows the thread of a positioning bolt (not shown) to pass through, allowing the thread of the positioning bolt to enter the central opening 121 from the outside of the clamp 120 via the threaded hole 123, and the length of the bolt entering the central opening 121 can be adjusted by rotation. In this configuration, the bracket 300 can be placed in the central opening 121 of the clamp 120 first, and then each positioning bolt can be rotated so that the thread of each positioning bolt passes through the corresponding threaded hole 123 and abuts against the bracket 300 in the central opening 121. Thus, the bracket 300 can be fixed in the central opening 121 by the positioning bolts. Furthermore, since the length of the thread of each positioning bolt entering the central opening 121 is adjustable, this configuration allows brackets 300 of different sizes and shapes to be fixed in the central opening 121, thereby improving the versatility of the assembly device 100.

[0038] refer to Figure 2 A schematic perspective view of an assembly apparatus according to another embodiment of the present disclosure is shown therein, and for clarity, Figure 2 Some components are also shown in partially cut-out form. Figure 2 The embodiments shown are the same as Figure 1 The difference in the illustrated embodiment is that the assembly device 100 further includes a support pad 150, which can be made of a cushioning material such as foam, silicone, or rubber, or of a wear-resistant material such as nylon, and is configured to be placed in the central opening 121 of the clamp 120 and abut against the bottom 330 of the bracket 300. In this configuration, the support pad 150 can support the bottom 330 of the bracket 300, thereby preventing undesirable wear on the bottom 330 of the bracket 300 when the bracket 300 vibrates horizontally along with the vibration platform 110, and preventing undesirable vertical vibration from being transmitted to the bracket 300 through the bottom 330 of the bracket 300.

[0039] In addition, such as Figure 2As shown, the support pad 150 can cover the bottom opening 312 of the bracket 300, thereby forming a pressure chamber 310c between the component 200 and the support pad 150 in the mounting hole 310. Air in this pressure chamber 310c can only escape through the gaps between the edge of the component 200 and the sidewall of the mounting hole 310, and the gap between the bottom 330 of the bracket 300 and the support pad 150. Both gaps are very small, so the air pressure in the pressure chamber 310c increases as the component 200 descends, thus resisting the pressure exerted by the counterweight 140. Therefore, the descent speed of the component 200 decreases as it approaches a designated depth, which helps to more accurately position the component 200 at the designated depth. Specifically, as... Figure 2 As shown, after component 200 is positioned at a specified depth, and another component 400 (e.g., another high-precision, fragile component such as an optical lens) is assembled in the same way, the air pressure in the pressure chamber 310c helps prevent component 200 from moving downwards from the specified depth due to its own weight and the air pressure between components 200 and 400 when the support 300 vibrates horizontally. In other words, the air pressure in the pressure chamber 310c also helps to keep the assembled component 200 at its specified depth.

[0040] It should be noted that the above assembly method is merely exemplary. During the assembly of components 200 and 400, the support pad 150 can also be placed in the central opening 121 of the clamp 120 and abut against the bottom 330 of the bracket 300 after component 200 is assembled and before the assembly of another component 400. That is, during the assembly of component 200, the support pad 150 is not placed in the central opening 121 of the clamp 120, so the aforementioned pressure chamber 310c is not established. Therefore, the pressure applied to component 200 by the counterweight 140 is not resisted by air pressure, which allows component 200 to quickly reach the specified depth. During the assembly of another component 400, the aforementioned pressure chamber 310c is established by the support pad 150, thereby using the air pressure in the pressure chamber 310c to hold component 200 at the specified depth to prevent component 200 from leaving its specified depth during the assembly of another component 400.

[0041] In particular, such as Figure 1 and Figure 2As shown, the cushioning pad 130 has a lower surface 131 for abutting against the component 200 and an upper surface 132 opposite to the lower surface 131 for abutting against the counterweight 140, and is provided with a central hole 133 extending from the lower surface 131 to the upper surface 132, so that the cushioning pad 130 is generally annular in shape. In this configuration, the central hole 133 significantly reduces the contact area between the cushioning pad 130 and the component 200, so that the cushioning pad 130 only contacts the component 200 along the edge of the component 200. This can more reliably prevent the component 200 from being contaminated or damaged, especially when the component 200 is an optical lens, which mainly uses its central portion to process light, and the above configuration can prevent the central portion of the optical lens from being contaminated or damaged.

[0042] refer to Figure 3 The diagram shows a schematic perspective view of the counterweight and buffer pad of the assembly device according to another embodiment of the present disclosure, and for clarity, Figure 3 The various components are shown in partially cut-out form. Figure 3 The embodiments shown are the same as Figure 1 and Figure 2 The main difference in the illustrated embodiment is that the bottom of the counterweight 140 is inserted into the central hole 133 of the cushioning pad 130, and the cushioning pad 130 has a step 134 formed in the central hole 133 for abutting against the bottom of the counterweight 140, so that a portion of the cushioning pad 130 (specifically, the portion above the step 134) surrounds the counterweight 140 and, in particular, clamps the counterweight 140 in the radial direction. That is, the portion of the cushioning pad 130 around the counterweight 140 can be pressed tightly against the counterweight 140. For example, when the counterweight 140 is inserted into the central hole 133, the portion of the cushioning pad 130 around the counterweight 140 can undergo elastic deformation, and the restoring force of this portion can generate a frictional force that holds the cushioning pad 130 and the counterweight 140 together. In this configuration, the cushioning pad 130 can be connected to the counterweight 140, which allows the cushioning pad 130 to be removed from the mounting hole 310 together with the counterweight 140 after the component 200 is assembled. This simplifies the post-assembly operation. Furthermore, since a portion of the cushioning pad 130 is located on the periphery of the counterweight 140, the cushioning pad 130 not only prevents the counterweight 140 from contacting the component 200 but also prevents the counterweight 140 from contacting the sidewall of the mounting hole 310. This prevents the counterweight 140 from impacting or even damaging the sidewall of the mounting hole 310 during horizontal vibration of the bracket 300.

[0043] In particular, such as Figure 3As shown, the cushioning pad 130 has an inner sidewall 135 for defining a central hole 133 and an outer sidewall 136 opposite to the inner sidewall 135 and intended to face the mounting hole 310. The cushioning pad 130 is configured such that the outer sidewall 136 is tapered, and more specifically, it slopes towards the inner sidewall 135 as it approaches the lower surface 131 of the cushioning pad 130. In this configuration, the tapered outer sidewall 136 of the cushioning pad 130 can guide the cushioning pad 130 and the counterweight 140 into the mounting hole 310, thereby preventing the cushioning pad 130 and the counterweight 140 from failing to enter the mounting hole 310 along with the component 200, which further ensures the smooth assembly of the component 200.

[0044] In particular, such as Figure 3 As shown, the assembly device 100 also includes a buffer washer 160, which may be made of a buffering material such as foam, silicone, or rubber, and is configured to be fitted onto the sidewall 141 of the counterweight 140 so that the buffer washer 160 can surround or encircle the counterweight 140. In particular, the counterweight 140 is provided with an annular groove 142 recessed from its sidewall 141 and extending in a circumferential direction (i.e., around the axis XX'), wherein a portion of the buffer washer 160 is received in the annular groove 142, while other portions protrude from the annular groove 142, that is, the outer diameter of the buffer washer 160 is larger than the diameter of the counterweight 140. In this configuration, the buffer washer 160 prevents the sidewall 141 of the counterweight 140 from contacting the sidewall of the mounting hole 310. Furthermore, the annular groove 142 of the counterweight 140 reliably holds the buffer washer 160 in place, preventing deformation or displacement due to friction from the sidewall of the mounting hole 310. Specifically, if the buffer washer 160 is used in conjunction with the aforementioned buffer pad 130, contact between the counterweight 140 and the sidewall of the mounting hole 310 can be completely prevented. In particular, the buffer pad 130 and the buffer washer 160 can have approximately the same outer diameter. In this configuration, when the counterweight 140 is located in the mounting hole 310, the buffer pad 130 and the buffer washer 160 orient the counterweight 140 vertically, ensuring that the counterweight 140 applies a vertically downward pressure to the component 200, thereby further ensuring smooth assembly of the component 200.

[0045] In addition to the assembly apparatus described above, this disclosure also aims to provide an improved assembly method that is implemented using the assembly apparatus proposed in this disclosure. (Reference) Figure 4 The diagram illustrates a schematic flowchart of an assembly method according to one embodiment of the present disclosure. Figure 4 As shown, the assembly method includes the following steps:

[0046] S100: Install the clamp 120 onto the vibration platform 110;

[0047] S200: Fix the bracket 300 on the clamp 120 so that the axis XX' of the mounting hole 310 is oriented in the vertical direction and the top opening 311 is open to the top;

[0048] S300: Insert a portion of component 200 into top opening 311, place cushioning pad 130 on component 200, and place counterweight 140 on cushioning pad 130;

[0049] S400: Start the vibration platform 110 so that the buffer pad 130 and counterweight 140 enter the mounting hole 310 along with component 200 under the action of gravity; and

[0050] S500: After the component 200 reaches the specified depth in the mounting hole 310, the vibration platform 110 is shut down, the buffer pad 130 and the counterweight 140 are removed from the mounting hole 310, and the bracket 300 is removed from the clamp 120.

[0051] Specifically, the assembly method may also include the following steps between steps S100 and S200:

[0052] Place the support pad 150 in the center opening 121 of the clamp 120 and insert the bracket 300 into the center opening 121 of the clamp 120 such that the support pad 150 abuts against the bottom 330 of the bracket 300 and covers the bottom opening 312 of the bracket 300.

[0053] In the above configuration, before the component 200 is assembled, the bottom opening 312 of the bracket 300 is covered by the support pad 150, thereby establishing the aforementioned pressure chamber 310c during the assembly of the component 200. The air pressure in the pressure chamber 310c reduces the descent speed of the component 200 as it approaches a specified depth, thereby enabling the component 200 to be positioned more accurately at the specified depth.

[0054] In particular, the assembly method may also include the following steps after step S500:

[0055] The support pad 150 is placed in the central opening 121 of the clamp 120, and the bracket 300 is inserted into the central opening 121 of the clamp 120 such that the support pad 150 abuts against the bottom 330 of the bracket 300 and covers the bottom opening 312 of the bracket 300; and

[0056] Repeat steps S200-S500 to assemble another component 400 into the mounting hole 310 of the bracket 300.

[0057] In the above configuration, after component 200 is assembled and before another component 400 is assembled, the bottom opening 312 of the bracket 300 is covered by the support pad 150. This prevents the aforementioned pressure chamber 310c from being established during the assembly of component 200, thereby allowing component 200 to quickly reach the specified depth. During the assembly of another component 400, the aforementioned pressure chamber 310c is established, thereby holding component 200 at the specified depth by the air pressure in the pressure chamber 310c, so as to prevent component 200 from leaving its specified depth during the assembly of another component 400.
