[0002] With the rapid development of manufacturing industries such as electronics and machinery, product structures are becoming increasingly complex, leading to ever-increasing demands for precision and efficiency in screw installation. Due to their small size, diverse specifications, and the large number and complex shapes of screw holes on products, the drawbacks of traditional manual screw installation processes are becoming increasingly apparent. Workers must manually select screws of the corresponding specifications on assembly lines, precisely align them with the screw holes, and then tighten them. This process is not only inefficient but also makes it difficult to guarantee the precision of manual installation, easily resulting in inaccurate screw placement and uneven tightening force. This not only affects the appearance quality of the product but may also adversely impact its performance and lifespan. Utility Model Content

[0048] See Figure 1-6As shown in the figure, this application embodiment provides a screw mounting device, including: a mounting platform 1, a screw guiding mechanism 2, a pressing mechanism 3, and a moving mechanism 4. The screw guiding mechanism 2 and the moving mechanism 4 are both mounted on the mounting platform 1. The moving mechanism 4 is located on the mounting platform 1 and is used to drive the screw guiding mechanism 2 to move on the mounting platform 1 to align with screw mounting points at different locations.

[0049] The mounting platform 1 is used to place the product to be installed with screws. As the basic support component of the entire screw installation device, the mounting platform 1 ensures the stability of the screw installation process. In practical applications, the mounting platform 1 is usually made of a sturdy material, such as sheet metal, to ensure sufficient strength and stability to withstand the various forces generated during screw installation.

[0050] In an optional embodiment, in order to ensure the levelness and stability of the mounting platform 1, support feet can be installed at the four corners of the mounting platform 1.

[0051] like Figure 1 and Figure 2 As shown, the screw guiding mechanism 2 includes a guide plate 21 and a guide member 23. The guide plate 21 is provided with a positioning hole 211, and the guide member 23 is installed in the positioning hole 211. The guide member 23 is used to guide the screw to move along the axial direction of the guide member 23.

[0052] The guide plate 23 serves to fix and support the guide component 23. The position of the guide component 23 is precisely determined through the positioning hole 211, ensuring that the screw moves along an accurate path during installation. By setting the guide plate 21 and the guide component 23 installed in the positioning hole 211, the screw can be precisely guided and positioned. Specifically, the external screw can move smoothly along the axial direction of the guide component 23 through the mating channel between the guide component 23 and the positioning hole 211 to a predetermined position below the guide plate 21. This provides reliable position guidance and constraint for the subsequent accurate installation of the screw, ensuring that the screw maintains a stable and precise movement trajectory during installation, effectively preventing screw offset or skew, and significantly improving the accuracy and stability of screw installation.

[0053] In an optional embodiment, the guide plate 21 may be provided with one or more positioning holes 211, and a guide member 23 may be installed in each positioning hole 211. When a single positioning hole 211 is provided, it is suitable for scenarios where a single screw is installed at a time, which can concentrate the guiding force and accurately complete the installation of a single screw; while when multiple positioning holes 211 are provided, multiple screws can be guided and positioned at the same time. With the corresponding feeding system, multiple screws can be installed in parallel, which can greatly improve the installation efficiency.

[0054] It should be noted that this embodiment does not specifically limit the shape of the guide plate 21, the number of the positioning holes 211 on the guide plate 21, or the specific position of each positioning hole 211. Figure 5 As shown, users can flexibly determine the outline of the guide plate 21 and the installation layout of the guide component 23 based on the actual distribution of screw mounting points on the product to be installed. In the above technical solution, the positioning holes 211 of the guide plate 21 can be arranged in a regular array, and the specifications of each hole are different. In this way, users can select the appropriate specifications of the positioning holes 211 to install the guide component 23 according to specific installation requirements. For example, for products with regular screw spacing, equally spaced positioning holes can be selected; for installation scenarios with diverse screw specifications, positioning holes with different inner diameters can be matched. Through this flexible configuration method, the screw installation requirements of various products can be quickly adapted, significantly improving the versatility and efficiency of the device.

[0055] See Figure 1-2 As shown, the pressing mechanism 3 is connected to the guide plate 21 and is used to drive the guide plate 21 closer to or away from the mounting platform 1.

[0056] The function of the pressing mechanism 3 is to provide the necessary pressure during screw installation, pressing the screw into the mounting hole. By designing the structure and performance of the pressing mechanism 3, the pressing force and speed can be precisely controlled, avoiding situations where the screw is not securely installed or the object being installed is damaged due to excessive or insufficient pressure.

[0057] In practical applications, the pressing mechanism 3 can be driven by a power component or operated manually to generate a thrust on the guide plate 21, so as to push the guide plate 21 closer to or away from the mounting platform 1;

[0058] See Figure 2 As shown, in some optional embodiments, the moving mechanism 4 includes a guide rail 41 and a slider 42. The guide rail 41 is fixed on the mounting platform 1, the slider 42 is connected to the guide rail 41 and slides in cooperation with the guide rail 41, and one end of the guide plate 21 is connected to the slider 42.

[0059] The slider 42 slides on the guide rail 41, causing the guide plate 21 to move linearly along the extension direction of the guide rail 41 on the mounting platform 1. The guide rail 41 provides a precise guide track for the slider 42, enabling the guide plate 21 to make stable and controllable displacements on the plane of the mounting platform 1. Regardless of whether the guide rail 41 is arranged horizontally, vertically, or diagonally, the slider 42 can drive the guide plate 21 to move along its trajectory, thereby achieving precise alignment between the guide plate 21 and the screw mounting points at different positions on the mounting platform 1, ensuring that the screw guiding mechanism 2 can quickly and accurately move the guide member 23 to the target mounting position. The combination of the guide rail 41 and the slider 42 has the advantages of simple structure, smooth movement, and high precision, and can meet the requirements for the movement of the guide plate 21 during screw installation.

[0060] In the above technical solution, the user can manually hold the pressing mechanism 3 and apply force to drive the guide plate 21 and the slider 42 to slide along the extension direction of the guide rail 41.

[0061] In other embodiments, a driving component connected to the slider 42, such as an electric push rod or a cylinder, can be provided. With the control of the driving component, the slider 42 is automatically driven to move the guide plate 21 along the guide rail 41.

[0062] See Figure 2 In some alternative embodiments, the guide rail 41 includes at least two bearings 411 and at least one slide rod 412;

[0063] The two ends of the slide rod 412 are connected to the bearing 411;

[0064] The slider 42 is sleeved on the slide rod 412 and can slide along the axial direction of the slide rod 412.

[0065] The bearing seat is made of aluminum alloy and is bolted to the mounting platform. The slide rod is a 12mm diameter stainless steel shaft, with both ends installed in the holes of the bearing seat and secured with nuts. The slider is made of engineering plastic and has through holes that fit the slide rod. The slider is fitted onto the slide rod, allowing it to slide along the slide rod's axis. One end of the guide plate is bolted to the slider.

[0066] This type of guide rail has good stability and load-bearing capacity, ensuring the smoothness of the guide plate during movement, while also facilitating installation and maintenance.

[0067] See Figure 3 As shown, in some optional embodiments, the pressing mechanism 3 includes a pressing handle 31, a pull rod 34, and an elastic element 35;

[0068] One end of the pull rod 34 is connected to the slider 42, and the other end passes through the guide plate 21;

[0069] The elastic element 35 is sleeved on the pull rod 34 and abuts between the guide plate 21 and the slider 42;

[0070] The downward handle 31 is connected to the through end of the pull rod 34.

[0071] One end of the pull rod 34 is securely connected to the slider 42, ensuring the stability of the pull rod 34 during movement. The other end of the pull rod 34 passes through the guide plate 21, allowing the pull rod 34 to move the guide plate 21 closer to or further away from the mounting platform 1.

[0072] The elastic element 35 can be a compression spring, with its outer diameter matching that of the pull rod 34 and its inner diameter slightly larger than that of the pull rod 34. The elastic element 35 is fitted onto the pull rod 34, with one end of the elastic element 35 abutting against the guide plate 21 and the other end of the elastic element 35 abutting against the slider 42.

[0073] The pressure handle 31 is connected to one end of the pull rod 34 that passes through the guide plate 21. When the operator applies pressure by operating the pressure handle 31, it moves the pull rod 34, which in turn moves the guide plate 21 closer to the mounting platform 1, thereby providing the required pressure for screw installation and realizing the pressure installation of the screw; when the pressure is released, under the action of the elastic element 35, the pull rod 34 moves the guide plate 21 away from the mounting platform 1 and returns to the initial position.

[0074] Furthermore, when the pressing handle 31 is subjected to significant pressure, the elastic element 35 will effectively absorb some of the impact force through its own deformation and compression, providing cushioning and shock absorption protection for the pressing handle 31. This design can prevent damage to the pressing mechanism and other components of the screw installation device due to excessive instantaneous pressure, while also preventing pressure from being directly transmitted to the screw and the object being installed, ensuring the smoothness and safety of the screw installation process, and improving the durability and reliability of the entire screw installation device.

[0075] In some alternative embodiments, such as Figure 4 As shown, an eccentric wheel assembly is provided on one end of the pressing handle 31 that is connected to the pull rod 34, so that when the operator operates the pressing handle 31, the force can be directly transmitted to the pull rod 34 through the eccentric wheel assembly, thereby driving the guide plate 21.

[0076] The downward handle 31 is rotatably connected to the pull rod 34 via the eccentric wheel assembly. This rotatable connection gives the downward handle 31 a certain degree of freedom of movement. The operator can rotate the downward handle 31 to change the position and state of the eccentric wheel assembly, thereby driving the pull rod 34 to perform corresponding movements.

[0077] The eccentric wheel assembly includes an eccentric wheel 32 disposed on the pressing handle 31 and a connecting shaft 33 connecting the eccentric wheel 32 and the pull rod 34.

[0078] It should be understood that the center of the eccentric wheel 32 does not coincide with the center of rotation. When the operator rotates and presses down the handle 31, the eccentric wheel 32 will move eccentrically. Due to the special structure of the eccentric wheel 32, it will generate a displacement change during the movement. This displacement change is transmitted to the pull rod 34 through the connecting shaft 33, enabling the pull rod 34 to achieve a larger stroke change. Compared with directly pushing the pull rod 34, using the eccentric wheel assembly can achieve a larger displacement of the pull rod 34 with a smaller operating force and a smaller rotation angle, thus making it easier and less strenuous to move the guide plate 21 closer to or away from the mounting platform 1, improving the efficiency of screw installation and the convenience of operation.

[0079] In an optional embodiment, the eccentric wheel is made of cast iron.

[0080] In practical applications, by employing the eccentric wheel assembly, the distance from different edges of the eccentric wheel 32 to the center of rotation varies during rotation. This causes different positions of the eccentric wheel 32 to contact the guide plate 21 during the pressing of the handle 31. Consequently, the thrust exerted on the guide plate 21 by the eccentric wheel 32 varies depending on the point of contact. Specifically, the frictional force is greatest when the contact point between the guide plate 21 and the eccentric wheel 32 is furthest or closest to the center of rotation, and the force required to operate the handle 31 is also greater. This allows for a regular variation in the thrust on the guide plate 21, enabling the user to operate the handle 31 according to actual needs, moving the guide plate 21 closer to or further away from the mounting platform 1.

[0081] See Figures 1-5 In some optional embodiments, the moving mechanism 4 further includes at least one positioning guide post 43 disposed on the slider 42. The positioning guide post 43 is vertically fixed on the slider 42. The guide plate 21 is provided with a guide post hole 212 at the position corresponding to the positioning guide post 43. The inner diameter of the guide post hole 212 matches the outer diameter of the positioning guide post 43 to form a clearance fit or transition fit relationship.

[0082] In an optional implementation, the positioning guide post 43 can be made of high-precision cylindrical steel with a polished surface to reduce friction. Meanwhile, the positioning guide post 43 is positioned on the guide plate 21.

[0083] When the slider 42 slides on the guide rail 41, the positioning guide post 43 moves synchronously and passes through the guide post hole 212. In this process, the cooperation between the positioning guide post 43 and the guide post hole 212 plays a dual role: on the one hand, it provides precise guidance for the movement of the guide plate 21, ensuring that the guide plate 21 slides smoothly along the axial direction of the positioning guide post 43, avoiding shaking or deviation during the movement; on the other hand, it shares the lateral force on the guide plate 21 when it moves, enhancing the structural rigidity and load-bearing capacity of the entire moving mechanism 4.

[0084] In some alternative embodiments, such as Figure 6 As shown, the guide member 23 includes a screw guide sleeve 231 with a central through hole. The central through hole of the screw guide sleeve 231 is adapted to the shape and size of the screw. The screw guide sleeve 231 is interference-fitted into the positioning hole 211, providing precise guidance for the screw and ensuring that the screw does not shift or skew during installation. The screw guide sleeve 231 is typically made of high-strength, wear-resistant material to ensure its stability and reliability during long-term use.

[0085] In practical applications, the screw guide sleeve 231 has a variety of central through holes, and the diameter of each through hole is precisely matched to the outer diameter of different screw models.

[0086] In some optional embodiments, the screw guide sleeve 231 includes a smooth inner wall. The smooth inner wall structure can effectively reduce the friction of the screw when passing through the guide sleeve, so that screws of different sizes, whether standard machine screws, self-tapping screws, or special sizes, can slide smoothly in the guide sleeve by their own weight or a slight external thrust, and accurately reach the screw installation point along the preset path.

[0087] like Figure 6 As shown, in some optional embodiments, to facilitate the placement and retrieval of screws, the mounting platform 1 has a material placement groove 11 on the side facing the screw guide mechanism 2; the guide member 23 can be horizontally moved above the material placement groove 11. Thus, before installing screws, the operator can pre-place the screws in the material placement groove 11. When screw installation is required, the moving mechanism 4 moves the guide member 23 above the material placement groove 11, and then, using the screw's own weight or other auxiliary means, the screw enters the guide member 23, completing the screw loading process. This improves the convenience and efficiency of screw installation and reduces the operator's steps.

[0088] In some optional embodiments, the material placement slot 11 is disposed adjacent to the guide rail 41, and the extending direction of the material placement slot 11 is consistent with the extending direction of the guide rail 41. In this way, the guide member 23 can reach the top of the material placement slot 11 more conveniently and quickly during movement, improving the efficiency of screw loading, while also making the entire device structure more compact and saving space.

[0089] See Figure 5 and Figure 6 In some optional embodiments, the screw guide mechanism 2 further includes an elastic limiting structure 22; the elastic limiting structure 22 is disposed at the connection between the guide member 23 and the guide plate 21.

[0090] The function of the elastic limiting structure 22 is to limit the movement range of the guide member 23 on the guide plate 21, prevent the guide member 23 from loosening or shifting during use, and ensure the accuracy of screw guidance. When the guide member 23 is subjected to external force, the elastic limiting structure 22 can provide a certain buffer and restoring force, so that the guide member 23 always remains in the correct position.

[0091] Specifically, the elastic limiting structure 22 is an elastic retaining ring, which can flexibly cooperate with the guide member 23 of different diameters to strengthen the connection between the guide member 23 and the guide plate 21.

[0092] In some optional embodiments, both ends of the guide member 23 extend beyond the guide plate 21; the extension length of the guide member 23 near the mounting platform 1 is greater than or equal to the extension length away from the mounting platform 1. Wherein, the extension length of the guide member 23 near the mounting platform 1 is as follows: Figure 3 As shown in Figure d, the extension length of the guide member 23 away from the mounting platform 1 is as follows: Figure 3 As shown in c.

[0093] Specifically, such as Figure 3 and Figure 6 As shown, by setting the guide member 23 to extend longer near the mounting platform 1, the user's operating distance can be shortened, allowing the screw to be guided from a farther position. By setting the guide member 23 to extend shorter towards the mounting platform 1, the guide member 23 can be better aligned with the screw mounting point on the product.

[0094] In an optional embodiment, the guide 23 can be connected to an external screw conveying device. With this design, screws can be smoothly conveyed from other equipment located far from the mounting platform 1, such as screw feeders or automatic sorting devices, along the channel of the guide 23 to a designated position on the mounting platform 1. This structural design not only reduces the tedious manual loading operation but also improves the automation level of the screw installation process, achieving efficient screw transfer from the feeding equipment to the installation point, greatly improving overall assembly efficiency, and also reducing problems such as screw installation position deviations caused by manual intervention.

[0095] The following describes the installation logic of the screw mounting device provided in the embodiments of this application:

[0096] First, place the screws to be installed into the material placement slot 11.

[0097] Then, the guide plate 21 is pushed to slide along the guide rail 41 by the moving mechanism 4, so that the guide member 23 moves above the material placement groove 11. Since the extension length of the guide member 23 near the mounting platform 1 is greater than the extension length away from the mounting platform 1, the screw can smoothly enter the central through hole of the screw guide sleeve 231 under its own gravity.

[0098] Next, the operator holds the pressing handle 31 and rotates the eccentric wheel assembly 32. Through the action of the eccentric wheel, the pull rod 34 drives the guide plate 21 to move downwards quickly, pressing the screw into the mounting hole of the electronic device housing. During the pressing process, the elastic element 35 is compressed, acting as a buffer to prevent excessive pressure from damaging the screw and the electronic device housing. After the screw is installed, the pressing handle 31 is released, the elastic element returns to its original shape, and the guide plate 21 resets.

[0099] Finally, the guide plate 21 is moved to the next screw installation position by the moving mechanism 4, and the above operation is repeated to complete the installation of all screws.

[0100] This embodiment provides a screw installation device, including an installation platform, a screw guiding mechanism, a pressing mechanism, and a moving mechanism. The screw guiding mechanism has a positioning hole on its guide plate. A guide element is installed in the positioning hole and guides the screw to move axially along the guide element, allowing the screw to move from the outside through the guide element and into the positioning hole to the side of the guide plate for direct alignment with screw installation points at different locations. The pressing mechanism drives the guide plate closer to or away from the installation platform. When a screw needs to be installed, the pressing mechanism moves the guide plate closer to the installation platform to apply pressure for screw installation; after installation, it drives the guide plate away from the installation platform to prepare for the next installation. The moving mechanism drives the guide plate to move on the installation platform, enabling the guide plate to quickly align with screw installation points at different locations and achieving efficient loading and unloading of products on the installation platform. Through the moving mechanism, the product and the guide element can be quickly and accurately aligned, greatly improving the efficiency of product positioning and screw installation.

[0101] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the embodiments.
