Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, specifically a tooling for screw fastening and inspection. Background Technology

[0002] In the production and assembly process of robotic vacuum cleaner base stations, the assembly quality of the cleaning and wastewater components directly affects the sealing performance and reliability of the base station. The connection and fixing of the water channel cover to the cleaning and wastewater tank body is one of the core processes. The water channel cover in the cleaning and wastewater components of the robotic vacuum cleaner base station needs to be locked to the cleaning and wastewater tank body with four bolts. Because the four bolts need to be locked from the bottom upside down, the water channel cover is located inside the tank, and there are other large and small protruding pillars on the front of the water channel cover, it is difficult to tighten it properly at the four corners of the water channel cover by applying force from the screw direction. This easily leads to obvious gaps after locking, causing a large number of quality defects. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a tooling for the inverted installation and inspection of screws. By setting a contoured force-bearing platform and a water tank limiting block, the water tank and water pipe cover can be inverted and fixed, exposing the operator's field of vision and providing a support platform for fixing the screws. At the same time, a metal sensor corresponding to the screw position is set on the contoured force-bearing platform to help detect whether the screw is finally fixed in place.

[0004] To achieve its technical objectives, this utility model adopts the following technical solution:

[0005] A fixture for the installation and inspection of screws includes a base, four water tank limiting blocks, and a contoured force-bearing platform. The water tank limiting blocks are vertically disposed on the upper surface of the base, with the four blocks positioned close to the four sides of the upper surface of the base, and are used to limit the position of the water tanks. The contoured force-bearing platform is installed between the water tank limiting blocks, and its upper surface has a limiting groove adapted to a water passage cover. The bottom of the limiting groove has a clearance groove adapted to a protrusion on the surface of the water passage cover. The upper surface of the contoured force-bearing platform has a detection hole, which corresponds to the position of the screws used to fix the water tanks and the water passage cover. A metal sensor is installed in the detection hole to detect whether the screws are properly secured.

[0006] Preferably, the detection range of the metal sensor is 0-0.5 mm.

[0007] Preferably, the depth of the limiting groove is between 0 and 0.5 mm.

[0008] Preferably, the contour-following force platform includes two parallel support plates perpendicular to the base and a force-bearing plate parallel to the base, and the upper surface of the force-bearing plate is provided with the limiting groove.

[0009] More preferably, the two ends of the lower surface of the force-bearing plate and the upper ends of the two support plates are detachably connected.

[0010] More preferably, the force-bearing plate and the support plate are detachably connected by fixing bolts, and the fixing bolts are provided at the four corners of the force-bearing plate, with the lower end of the fixing bolts threadedly connected to the upper end of the support plate.

[0011] Preferably, the water tank limiting block abuts against the outer wall of the water tank.

[0012] The beneficial effects of this utility model are as follows:

[0013] This invention effectively solves the problem in the cleaning and sewage assembly of a robotic vacuum cleaner base station where the water channel cover is located inside the housing, requiring four bolts to be installed upside down from the bottom, and the locking position is difficult to tighten. It reduces the large-scale quality defects caused by improper tightening and obvious gaps in traditional assembly. Through the stable cooperation of the water tank limiting block and the contour-following force platform, the water tank and water channel cover are inverted and firmly positioned, fully exposing the operator's field of vision and providing reliable support for the installation of the bottom screws. Simultaneously, the integrated metal sensor can detect the bolt installation status, automatically alarming when bolts are missing or not tightened, thereby improving assembly quality. Furthermore, the detachable design of the contour-following force platform allows for the replacement of force plates to adapt to different component specifications, making operation simple and efficient, improving assembly pass rate, reducing quality risks, and increasing production efficiency, making it more suitable for large-scale production needs.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within the components of a compatible model. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, unless otherwise specified, all components used in this application are commercially available components, and the connection between different components can be achieved through conventional technical means.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0023] like Figure 4 As shown, assembling the water tank 8 and water channel cover 9 of the sweeping robot requires a worker to install four locking screws 7 from the bottom. The surface of the water channel cover 9 has multiple protrusions 13 (actually anti-foolproof posts, used to distinguish different sizes of water channel covers 9). Due to the irregular shape of the water channel cover 9 and the special installation method of the water tank 8 and water channel cover 9, this utility model provides a screw-installation and inspection fixture to assist in the rapid fixing of both components; as shown... Figures 1-4 As shown, the system includes a base 1, four water tank limiting blocks 2, and a contoured force-bearing platform 3. The water tank limiting blocks 2 are vertically arranged on the upper surface of the base 1, and the four water tank limiting blocks 2 are respectively close to the four sides of the upper surface of the base 1. The water tank limiting blocks 2 are used to limit the position of the water tank 8, and the water tank limiting blocks 2 abut against the outer side wall of the water tank 8. The contoured force-bearing platform 3 is installed between the water tank limiting blocks 2, and the upper surface of the contoured force-bearing platform 3 is provided with a limiting groove 4 that matches the water passage cover 9. The bottom of the limiting groove 4 is provided with a clearance groove 5 that matches the protrusion 13 on the surface of the water passage cover 9. The upper surface of the contoured force-bearing platform 3 is provided with a detection hole, which corresponds to the position of the locking screw 7 used to fix the water tank 8 and the water passage cover 9. A metal sensor 6 is installed in the detection hole, and the metal sensor 6 is used to detect whether the locking screw 7 is fixed in place.

[0024] It should be noted that the detection range of the metal sensor 6 is 0-0.5mm; the depth of the limiting groove 4 is between 0-0.5mm; at the same time, the base 1 is equipped with a detection circuit that is electrically connected to the metal sensor 6. The detection circuit is used to cooperate with the metal sensor 6 to detect the screw 7.

[0025] Preferably, the contour-following force platform 3 includes two parallel support plates 11 perpendicular to the base 1 and a force plate 10 parallel to the base 1, with a limit groove 4 provided on the upper surface of the force plate 10.

[0026] It is understandable that by using the water tank limiting block 2 in conjunction with the limiting groove 4, the water circuit cover 9 and the water tank 8 are limited and fixed, so as to prevent the water circuit cover 9 and the water tank 8 from shifting when the screw 7 is installed, which would cause the screw 7 to be not properly installed and fixed. At the same time, during the installation of the screw 7, the force plate 10 can provide support force to bear the downward pressure of the screw installation.

[0027] More preferably, the two ends of the lower surface of the load-bearing plate 10 and the upper ends of the two support plates 11 are detachably connected; specifically, such as Figure 3 As shown, the load-bearing plate 10 and the support plate 11 are detachably connected by fixing bolts 12. Fixing bolts 12 are provided at the four corners of the load-bearing plate 10, and the lower end of the fixing bolts 12 is threadedly connected to the upper end of the support plate.

[0028] The detachable design of the contoured force-bearing platform 3 is more suitable for large-scale production operations. It can produce different force-bearing plates 10 for different water pipe covers 9 and make them easy to replace, thereby improving production efficiency.

[0029] The operation method of this utility model is as follows:

[0030] First, fasten the water pipe cover 9 (including the 3 inserted silicone tubes) onto the body of the water tank 8; then, invert both onto the fixture, so that the outer wall of the water tank 8 abuts against the water tank limiting block 2, and the water pipe cover 9 is embedded in the limiting groove 4 on the surface of the force plate 10 of the contour force platform 3, so that the protrusion 13 on the surface of the water pipe cover 9 is inserted into the clearance groove 5, thereby fixing the water tank 8 and the water pipe cover 9 onto the fixture; then, use four locking screws 7 to complete the fixing of the water pipe cover 9 to the water tank 8; during this process, the metal sensor 6 will automatically detect whether the locking screws 7 are fixed in place and whether screws are missing. If the screws are not fully locked or not locked in place, an alarm will be triggered by the detection circuit; the operator removes the component with the locking screws 7 locked; the above actions are repeated sequentially with the previous one.

[0031] Although the embodiments of this utility model have been described in the specification, these embodiments are merely illustrative and should not limit the scope of protection of this utility model. Various omissions, substitutions, and modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
