Description

Technical Field

[0001] The utility model relates to the technical field of semi-automatic screw locking equipment, and more specifically, it is a semi-automatic platform for screw locking. Background Art

[0002] In the electronics industry, automobile manufacturing, and other industries that require the assembly of a large number of small parts, screw locking is a common and important step. Different from automated screw locking equipment, in order to adapt to different product types, screw specifications, and locking positions and reduce production and processing costs, a semi-automatic screw locking platform is often used.

[0003] In the current prior art, when the semi-automatic screw locking platform transports the product to the working area, the product is clamped in a way of clamping on both sides and fixing on the other two sides. This method is not conducive to the precise positioning of the product and may cause defects. In addition, the protective cover plate on its working area is often fixed and is provided with several through holes leading to the locking positions or a cover plate that needs to be manually opened before locking. The former is not conducive to expanding the application range of the machine, and objects are likely to fall from the through holes during the operation of the machine, affecting the operation of the machine and the yield rate of the product. The latter increases the working intensity of the operator, reduces the efficiency of screw locking, and neither of them is conducive to protecting the safety of the operator. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a semi-automatic platform for screw locking, aiming to solve the technical problems existing in the prior art, such as poor accuracy of product positioning, external interference affecting the operation of the machine and the yield rate of the product, high working intensity and low efficiency of the operator, and low safety factor of the equipment.

[0005] To solve the above technical problems, the utility model provides a semi-automatic platform for screw locking, including: a frame, on which a horizontal conveyor mechanism, a lifting mechanism, and a cover plate mechanism are provided. The lifting mechanism is located below the horizontal conveyor mechanism, and the cover plate mechanism is located above the horizontal conveyor mechanism. A first clamping component is provided on the lifting mechanism, and a second clamping component is provided on the horizontal conveyor mechanism. The first clamping component and the second clamping component clamp the product in different directions respectively. The cover plate mechanism includes a movable cover plate and a cover plate driving member for driving the movable cover plate to move relative to the frame.

[0006] In the above solution, the horizontal conveying mechanism and the lifting mechanism can automatically convey the product to the working area above the horizontal conveying mechanism, which is beneficial to reducing the working intensity of the operator and improving the working efficiency of screw fastening; while the product is conveyed to the working area above the horizontal conveying mechanism, the first clamping assembly and the second clamping assembly can clamp the product in multiple directions, so that the product can be completely fixed in the specified position, which is beneficial to improving the positioning accuracy of the product; when the product is not conveyed to the working area, the cover plate mechanism can cover, isolate and protect the working area above the horizontal conveying mechanism and the lifting mechanism, and automatically open the movable cover plate for screw fastening until the product is conveyed to the working area, and cover, isolate and protect the working area again when the screw fastening is completed, which is beneficial to preventing foreign objects from entering this area and damaging the machine or the product, and can also prevent the operator from touching the running machine and causing safety accidents.

[0007] Preferably, the cover plate mechanism further includes a lifting assembly for driving the lifting of the movable cover plate, and a guiding assembly for guiding the movement of the movable cover plate, and the cover plate driving member is connected to the movable cover plate through a transmission assembly.

[0008] In the above solution, the output end of the lifting assembly is movably connected to the movable cover plate, and a guiding assembly is provided at the connection between the movable cover plate and the lifting assembly. The cover plate driving member drives the movable cover plate to move along the direction of the guiding assembly through the transmission assembly, so that the movable cover plate approaches or moves away from the working area, which is beneficial to improving the movement accuracy of the movable cover plate; when the movable cover plate covers and moves away from the working area, the weight of the movable cover plate itself will cause its height to change to a certain extent. In order to prevent the movable cover plate from colliding with different products and improve the applicability to different types of products, the lifting assembly is used to finely adjust the height of the movable cover plate; the transmission assembly is beneficial to providing higher flexibility for the connection design between the cover plate driving member and the movable cover plate.

[0009] Preferably, the lifting assembly includes a fixed seat provided on the frame, a bearing platform provided on the fixed seat, and a lifting driving member for driving the bearing platform to lift, and the movable cover plate is movably arranged on the bearing platform.

[0010] In the above solution, the fixed seat can set the height of the movable cover plate above the horizontal conveying mechanism, and the bearing platform can also adjust the height of the movable cover plate, which is beneficial to adjusting the distance between the movable cover plate and the product, preventing the lifting mechanism from colliding with the movable cover plate when lifting the product, and when the movable cover plate needs to be replaced, it is not necessary to replace the entire cover plate mechanism, which is beneficial to subsequent maintenance.

[0011] Preferably, the guiding assembly includes a linear guide rail and a moving seat respectively provided on the bearing platform and the movable cover plate, and the moving seat is slidably clamped on the linear guide rail.

[0012] In the above solution, the movable cover plate and the bearing platform are slidably clamped through linear guide rails and sliding seats. The linear guide rails can cover the entire movement process of the movable cover plate and, together with the sliding seats, provide a more stable and accurate movement process and movement guidance for the movable cover plate. Additionally, when the linear guide rails and the movable seats are not provided, the guiding assembly is simplified to a guiding structure, that is, corresponding sliding grooves and bumps are provided on the contact surface between the movable cover plate and the bearing platform. Therefore, the linear guide rails and the movable seats also replace this kind of guiding structure, so that when wear or damage occurs at the sliding clamping position of the movable cover plate or the bearing platform, the whole component does not need to be replaced, which is beneficial to reducing the maintenance cost.

[0013] Preferably, the transmission assembly includes a transmission gear provided at the output end of the cover plate driving member and a rack provided on the movable cover plate, and the transmission gear is meshed and connected with the rack.

[0014] In the above solution, the cover plate driving member drives the movable cover plate to move on the bearing platform through the transmission assembly, so that the movable cover plate covers or moves away from the working area above the horizontal conveying mechanism. The meshing connection mode of the transmission gear and the rack can only cause relative movement between the movable cover plate and the bearing platform, which can simplify the structure of the cover plate mechanism and further improve the movement stability of the movable cover plate.

[0015] Preferably, an installation opening is provided on the movable cover plate, and a transparent cover plate is provided at the installation opening.

[0016] In the above solution, when the transparent cover plate covers the working area on the horizontal conveying mechanism, the operating states of the components below the movable cover plate, whether the product is conveyed to the working area, and whether foreign objects fall below the movable cover plate can be observed from the outside, which is beneficial to improving the protection performance of the cover plate mechanism, improving the monitoring and recognition ability of the machine operating state, and facilitating the timely discovery of problems.

[0017] Preferably, a blocking assembly for blocking the product is further provided on the horizontal conveying mechanism. The blocking assembly includes a blocking driving member, a connecting plate provided at the output end of the blocking driving member, and a baffle provided on the connecting plate. A plurality of mounting holes are arranged at intervals on both the connecting plate and the baffle.

[0018] In the above solution, the product moves synchronously with the horizontal conveying mechanism. The blocking driving member drives the baffle through the connecting plate, so that the baffle is inserted into the transportation route of the product to block its continuous synchronous movement with the horizontal conveying mechanism, and waits to be lifted by the lifting mechanism to ensure that the lifting mechanism has sufficient redundant time to lift the product, which is beneficial to adjusting the rhythm between components; the baffle can be installed at different positions on the connecting plate through these mounting holes to adjust the distance that the baffle extends out of the connecting plate to adapt to different types of products and ensure that the product can be lifted by the lifting mechanism.

[0019] Preferably, the first clamping assembly includes a support table provided at the output end of the lifting mechanism, movable clamping blocks and fixed clamping blocks spaced on both sides of the support table, and a first driving member provided on the support table, and the first driving member is used to drive the movable clamping block to approach or move away from the fixed clamping block.

[0020] In the above solution, when the product is transported by the horizontal conveying mechanism above the lifting mechanism, it will be blocked by the blocking mechanism. Subsequently, the lifting mechanism uses the support table to lift the product, and the first driving member will drive the movable clamping block to push one side of the product, so that the opposite side abuts against the fixed clamping block, realizing clamping of the product in two opposite directions; using a movable clamping block on a single side can simplify the structural design of the first clamping assembly, improve the adaptability to different types of products, and at the same time is beneficial to reducing production and processing costs.

[0021] Preferably, the second clamping assembly includes a limiting table, a clamping table provided at the top of the horizontal conveying mechanism, and a second driving member. The limiting table and the clamping table are arranged opposite to each other, and the second driving member is used to drive the clamping table to approach or move away from the limiting table.

[0022] In the above solution, when the product is transported by the horizontal conveying mechanism to the lifting mechanism and is blocked by the blocking mechanism, the lifting mechanism lifts the product to the plane where the limiting table and the clamping table are located. Then the limiting table and the clamping table can limit the position of the product on the horizontal conveying mechanism, prevent the product from shifting in the direction perpendicular to the conveying direction or even detaching from the horizontal conveying mechanism, which may lead to the failure of clamping of the first clamping assembly and the second clamping assembly. At the same time, it provides a reference for the distance between the movable cover plate and the product; the second driving member drives the clamping table to push one side of the product, so that the other side of the product abuts against the limiting table, realizing clamping of the remaining two opposite directions of the product, completing multi-directional clamping of the product, which is beneficial to improving its positioning accuracy; similarly, only using a movable convex platform on one side can simplify the structural design of the second clamping assembly, reduce production and processing costs, and is also beneficial to improving the adaptability to different types of products.

[0023] Preferably, a supporting hand plate is further provided on the frame. The supporting hand plate is located above the horizontal conveying mechanism and is provided with a working opening for the movable cover plate to move.

[0024] In the above solution, the supporting handboard has a structure of a semi - enclosed movable cover plate, which separates the nearby personnel from the movable cover plate mechanism, preventing them from touching the operating cover plate mechanism. Moreover, it also covers the area not covered by the movable cover plate, preventing the operator from touching the operating components and causing safety accidents, further improving the protection and isolation performance of the cover plate mechanism. At the same time, the supporting handboard also provides a space for the operator to place both hands and can also be used to place or design the placement of auxiliary tools, improving the space utilization rate and design flexibility of the machine.

[0025] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0026] The first clamping component and the second clamping component are adopted to clamp the product in multiple directions, which is beneficial to improving the positioning accuracy of the product. The cover plate mechanism is adopted to cover, isolate and protect the working area above the horizontal conveying mechanism and the lifting mechanism, and can automatically control the forward and backward movement of the movable cover plate to cover or disengage from the working area when the product enters the working area and finishes locking the screws, which is beneficial to reducing the working intensity of the operator, improving the working efficiency of screw locking, and improving the safety performance of the semi - automatic screw - locking platform.

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality" means two or more unless otherwise specifically defined.

[0037] In this embodiment, please refer to Figures 1 to 5As shown in the figure, the utility model provides a semi-automatic platform for screw attachment, which includes a frame 100. A horizontal conveying mechanism 300, a lifting mechanism 200, and a cover plate mechanism 400 are provided on the frame 100. The lifting mechanism 200 is located below the horizontal conveying mechanism 300, and the cover plate mechanism 400 is located above the horizontal conveying mechanism 300. A first clamping assembly 210 is provided on the lifting mechanism 200, and a second clamping assembly 310 is provided on the horizontal conveying mechanism 300. The first clamping assembly and the second clamping assembly 310 clamp the product 600 in different directions respectively. The cover plate mechanism 400 includes a movable cover plate 410 and a cover plate driving member 420 for driving the movable cover plate 410 to move relative to the frame 100.

[0038] It can be understood that when the product 600 is conveyed by the horizontal conveying mechanism 300 from the conveyor line to a certain position, it will be lifted by a certain distance by the lifting mechanism 200 located below the conveyor line. This final position is defined as the working area. During the lifting process to the working area, the first clamping assembly 210 and the second clamping assembly 310 will clamp and fix the product 600 in multiple directions along different directions, specifically in the four directions of front, back, left, and right. After the attachment is completed, the above steps are executed in reverse order, and the completed product 600 is placed back on the horizontal conveying mechanism 300 and flows into the next process. During the process of the cover plate mechanism 400 covering and isolating the working area with the movable cover plate 410 when the product 600 is not conveyed to the working area and replacing the next product 600 after the attachment is completed, the movable cover plate 410 is opened when the product 600 is conveyed to the working area and the positioning is completed.

[0039] In addition, for products 600 with different shapes and structures, the clamping structures and multi-directional clamping directions of the first clamping assembly 210 and the second clamping assembly 310 are based on being able to restrict their movement in the horizontal direction.

The cover plate driving member 420 drives the movable cover plate 410 to move along the direction of the guiding assembly 440 through the transmission assembly 450, so that the movable cover plate 410 approaches or moves away from the working area. When the movable cover plate 410 covers and moves away from the working area, the weight of the movable cover plate 410 itself will cause its height to change to a certain extent. To prevent the movable cover plate 410 from colliding with different products 600 and improve the applicability to different types of products 600, the lifting assembly 430 is used to finely adjust the height of the movable cover plate 410.

[0042] In addition, in some embodiments, after determining the required height of the movable cover plate 410, the lifting assembly 430 can be replaced with only a fixed seat. At this time, the movable cover plate 410, the guiding assembly 440, and the transmission assembly 450 are all arranged on the top of the fixed seat.

[0043] Specifically, the lifting assembly 430 includes a fixed seat 431 arranged on the frame 100, and a bearing platform 433 and a lifting driving member 435 arranged on the fixed seat 431. The lifting driving member 435 is used to drive the bearing platform 433 to lift and lower, and the movable cover plate 410 is movably arranged on the bearing platform 433.

[0044] It can be understood that the fixed seat 431 and the bearing platform 433 set the height of the movable cover plate 410 above the horizontal conveying mechanism 300 and can adjust the height of the movable cover plate 410. The lifting guide rail 432 and the lifting seat 434 are respectively arranged on the bearing platform 433 and the fixed seat 431. The bearing platform 433 is slidably clamped on the fixed seat 431 through the lifting guide rail 432 and the lifting seat 434, and the lifting guide rail 432 and the lifting seat 434 can be arranged in the opposite direction, as long as the lifting driving member 435 can drive the bearing platform 433 to lift and lower.

[0046] In addition, in some embodiments, the lifting guide rail 432 and the lifting seat 434 can be simplified to a clamping structure between the contact surfaces of the fixed seat 431 and the bearing platform 433, such as a sliding groove and a convex block.

[0047] More specifically, the guiding assembly 440 includes a linear guide rail 441 and a moving seat 442 respectively arranged on the bearing platform 433 and the movable cover plate 410, and the moving seat 442 is slidably clamped on the linear guide rail 441.

[0048] It can be understood that the moving seat 442 is arranged on the bearing platform 433, the linear guide rail 441 is arranged on the movable cover plate 410, and the movable cover plate 410 is slidably clamped on the bearing platform 433 through the linear guide rail 441 to achieve movement guidance. The linear guide rail 441 can cover the entire movement process of the movable cover plate 410; the linear guide rail 441 and the moving seat 442 can also be arranged conversely.

[0049] In addition, in some embodiments, the linear guide rail 441 is arranged on the bearing platform 433 and extends towards the working area, and the moving seat 442 is arranged on the movable cover plate 410; the guiding assembly 440 can also be multiple spaced apart ones.

[0050] In addition, when the linear guide rail 441 and the moving seat 442 are not provided, the guiding assembly 440 is simplified to a matching sliding clamping structure, such as a convex block and a groove, that is, corresponding sliding grooves and convex blocks are arranged on the contact surface between the movable cover plate 410 and the bearing platform 433.

[0051] More specifically, the transmission assembly 450 includes a transmission gear 451 arranged at the output end of the cover plate driving member 420 and a rack 452 arranged on the movable cover plate 410, and the transmission gear 451 is meshed and connected with the rack 452.

[0052] It can be understood that the orientation and length of the rack 452 need to ensure that the movable cover plate 410 can cover or disengage from the working area; the cover plate driving member 420 can be arranged at the top or bottom of the bearing platform 433. When arranged at the top, the tooth part of the rack 452 should face the up and down directions. When arranged at the bottom, the output end of the cover plate driving member 420 extends between the bearing platform 433 and the movable cover plate 410, and the tooth part of the rack 452 should face the left and right directions.

[0053] In addition, the rack 452 can be multiple; different connection methods can also be adopted between the output end of the cover plate driving member 420 and the rack 452.

Correspondingly, the rack 452 is arranged on the bearing platform 433, and the output end of the cover plate driving member 420 passes through the movable cover plate 410 and is connected with the rack 452 through the transmission gear 451.

[0055] In this embodiment, please refer to Figure 3 As shown, an installation opening 411 is provided on the movable cover plate 410, and a transparent cover plate 412 is provided at the installation opening 411.

[0056] It can be understood that the movable cover plate 410 has a "concave" structure, and the sizes of the installation opening 411 and the transparent cover plate 412 are similar to those of the product 600, and can enable the operator to observe most positions of the product 600.

[0057] In addition, in some embodiments, the installation opening 411 is provided with a sliding groove, and the transparent cover plate 412 is clamped in the sliding groove for maintenance.

[0058] In addition, in some embodiments, the movable cover plate 410 can be made of a transparent material, in which case there is no need to provide an opening and the transparent cover plate 412.

[0059] In this embodiment, please refer to Figure 1 、 2 and Figure 4 As shown, the horizontal conveyor mechanism 300 is further provided with a blocking assembly 320 for intercepting the product 600. The blocking assembly 320 includes a blocking driving member 321, a connecting plate 322 provided at the output end of the blocking driving member 321, and a baffle 323 provided on the connecting plate 322. A plurality of mounting holes 324 are arranged at intervals on both the connecting plate 322 and the baffle 323.

[0060] It can be understood that the baffle 323 has an "L" - shaped structure. The product 600 moves synchronously with the horizontal conveyor mechanism 300. The blocking driving member 321 drives the baffle 323 through the connecting plate 322, so that the baffle 323 is inserted into the transportation route of the product 600 to block its continuous synchronous movement with the horizontal conveyor mechanism 300 and wait to be lifted by the lifting mechanism 200 to ensure that the lifting mechanism 200 has sufficient redundant time to lift the product 600; the arrangement direction of the mounting holes 324 is the same as the conveying direction.

[0061] In this embodiment, please refer to Figure 2 and Figure 5 As shown, the first clamping assembly 210 includes a support platform 211 provided at the output end of the lifting mechanism 200, movable clamping blocks 212 and fixed clamping blocks 213 arranged at intervals on both sides of the support platform 211, and a first driving member 214 provided on the support platform 211. The first driving member 214 is used to drive the movable clamping block 212 to approach or move away from the fixed clamping block 213.

[0062] It can be understood that the shapes and structures of the movable clamping block 212 and the fixed clamping block 213 depend on the product 600; the movable clamping block 212 and the fixed clamping block 213 are oppositely arranged to clamp two opposite sides of the product 600, which are the left and right sides in this embodiment, that is, the conveying direction of the horizontal conveyor mechanism 300; the position of the support platform 211 does not affect the lifting of the product 600.

[0063] In addition, in some embodiments, the first clamping assembly 210 can also clamp the product 600 in the front - to - back direction, that is, the direction perpendicular to both the conveying direction of the horizontal conveyor mechanism 300 and the direction of product lifting.

[0065] It can be understood that the limiting platform 311 and the clamping platform 312 clamp the product 600 in the front-rear direction. The lengths of the limiting platform 311 and the clamping platform 312 need to cover the working area to prevent the lifting mechanism 200 from shifting or deviating from the working area after lifting the product 600.

[0066] In addition, in some embodiments, the second clamping assembly 310 can also clamp the product 600 in the left-right direction. At this time, the limiting platform and the clamping platform straddle the horizontal conveying mechanism in the front-rear direction.

[0067] In addition, in some embodiments, two opposite limiting platforms 311 can be provided, the length of which is equal to the length of the horizontal conveying mechanism 300.

[0069] It can be understood that the supporting hand plate 500 has a "concave" structure. Its working opening semi-surrounds the movable cover plate 410 and covers the area not covered when the movable cover plate 410 is closed.

[0070] In addition, an anti-slip pad can be provided on the supporting hand plate 500.

[0071] The specific application process of the present utility model is as follows:

[0072] At the beginning, the movable cover plate 410 is in a state of covering the working area; the product 600 is conveyed from the horizontal conveying mechanism 300 to below the working area, and the lifting assembly 430 located below the horizontal conveying mechanism 300 lifts the product 600 by a certain distance; during the lifting process, the first driving member 214 drives the movable clamping block 212 to push one side of the product 600, so that the opposite side abuts against the fixed clamping block 213, realizing the clamping of the product 600 in two opposite directions, and this direction is the left-right direction. The second driving member 313 drives the clamping table 312 to push one side of the product 600, so that the opposite side abuts against the limiting table 311, realizing the clamping of the product 600 in the remaining two opposite directions, that is, the front-back direction, and completing the multi-directional clamping and positioning of the product 600; the cover plate driving member 420 drives the movable cover plate 410 through the transmission gear 451 and the rack 452, and the movable cover plate 410 opens the working area along the guiding directions of the linear guide rail 441 and the moving seat 442. Then, the lifting assembly 430 finely adjusts the height of the movable cover plate 410, and the operator starts to lock the screws; after the locking is completed, the movable cover plate 410 is restored to the state of covering the working area in the reverse order of the foregoing steps. The second clamping assembly 310 and the first clamping assembly 210 release the clamping of the product 600, and the lifting mechanism 200 lowers the product 600 back to the horizontal conveying mechanism 300 to continue to be conveyed to the next process.

[0073] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
