Description

Technical Field

[0001] This utility model relates to the field of fixture technology, and in particular to a screw-locking fixture that can protect the appearance of a product. Background Technology

[0002] An automatic screw tightening machine is an automated device used to tighten screws quickly and accurately. It can improve production efficiency, reduce labor costs, and ensure consistent screw tightening.

[0003] Screw tightening fixtures are specialized devices used for automated screw tightening, improving work efficiency and ensuring screw tightening quality. Depending on the application and requirements, screw tightening fixtures can be categorized into manual, pneumatic, and electric types.

[0004] A relevant reference is Chinese Patent No. CN209256798U, which discloses a screw-locking fixture, including a housing, a protective plate assembly, and a support assembly. The support assembly is mounted on the housing and supports a plate to be screwed. A screw sleeve is provided on the protective plate assembly for screw guidance. A control circuit is located inside the housing. One end of the protective plate assembly is rotatably mounted on the housing. When the plate is placed on the support assembly and the protective plate assembly covers the plate, it triggers the control circuit inside the housing, activating an electric screwdriver to perform the screw-locking operation.

[0005] This structure uses plate fixing to assist screws in securing the interior of the plate. Although this structure provides localized locking, the locking force is uneven. When the support in the middle of the plate is insufficient, the plate may dent, causing the screw holes to misalign and the screws to break inside the plate. Furthermore, the plate fixing method easily scratches the surface of the product. On the other hand, when used in specific installation environments, such as those requiring visibility and light transmission, this structure lacks the ability to assist light transmission, necessitating further processing and modification, increasing procedures and reducing work efficiency. Therefore, the inventors have proposed a screw-locking fixture that protects the appearance of the product to solve the aforementioned technical problems. Utility Model Content

[0006] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the aforementioned problems.

[0007] A screw-locking fixture for protecting the appearance of a product includes a protective cover, a diagnostic box, and a base plate. The diagnostic box is installed between the protective cover and the base plate. One end of the diagnostic box is a pre-compression area, and the surface of the pre-compression area is connected with pre-compression cotton. The pre-compression cotton and the pre-compression area are separated. One end of the pre-compression cotton is attached to one end of the protective cover. A main control circuit board is installed inside the diagnostic box. The main control circuit board is electrically connected to a light-illuminating board. Both the main control circuit board and the light-illuminating board are installed inside the diagnostic box via mounting bases. The diagnostic box and the mounting base are both light-transmitting. The protective cover is a light-transmitting acrylic sheet. Several mounting holes are opened on the surface of the protective cover. Stainless steel guide sleeves for auxiliary screw fastening are connected to the inner surface of the mounting holes.

[0008] This utility model protects the product's appearance by using a stainless steel guide sleeve, protective cover plate, pre-compression area, and pre-compression cotton for screw fastening, preventing damage to the product's appearance caused by the pressure generated during mold closing. After the product is initially fixed, this screw-fastening fixture is placed on the worktable of an automatic screw machine to facilitate the screw fastening process. This structure can be used with automatic screw machines or manual screw fastening. It adopts a simplified structure to achieve the processes of lighting, alignment, and positioning. While assisting in screw fastening, it is also convenient for operators to operate, allowing them to intuitively observe the light transmittance of the holes and avoid blind holes or hole blockage. This prevents abnormal situations from occurring during the screw fastening process, which could cause the screw to deviate from its track and break inside the product.

[0009] Furthermore, an adjustment frame is installed at one end of the base plate, and an adjustment rod is connected to the surface of the adjustment frame. The adjustment rod is connected to the protective cover plate, and the position of the protective cover plate can be adjusted horizontally by twisting the adjustment rod. This setting increases the flexibility of the structure and makes it easier to adapt to the needs of different working environments. When the position of the diagnostic box cannot be adjusted, the adjustment rod can be twisted to move the protective cover plate horizontally, so that the mounting holes on the surface of the protective cover plate and the stainless steel guide sleeve are aligned with the holes inside the product that need to be fastened. This achieves a flexible adjustment effect and prevents the product from shifting during the screw fastening process, which could cause the screw to deviate from its track and break inside the product.

[0010] Furthermore, the surface of the base plate is provided with a limiting slot for placing the diagnostic box, and the surface of the diagnostic box is provided with a limiting block for connecting screws to assist in position limitation.

[0011] The limiting slot on the base plate surface cooperates with the limiting block on the surface of the diagnostic box to ensure that the diagnostic box is accurately placed on the base plate, facilitating screw fixing and improving assembly convenience and stability. It also reduces the possibility of misoperation and prevents the product from shifting during screw tightening, which could cause the screw to deviate from its track and break inside the product. If any signs of shifting are found, the installation position of the limiting block can be adjusted to place the diagnostic box in the designated installation position for easy screw tightening. The size of the limiting slot is larger than the size of the diagnostic box to allow for adjustment of the diagnostic box.

[0012] Furthermore, the main control circuit board is electrically connected to a data interface and a power socket, both of which extend to the surface of the diagnostic box. This structure facilitates quick connection and disconnection of data transmission and power by operators, improving operational convenience and maintenance efficiency. The data interface enables data transmission and communication between devices, and uses an external display device for real-time monitoring to ensure the overall operation remains normal and stable, reducing the number of risk checks and the probability of accidents. The power socket is used to connect an external power cord, allowing the main control circuit board to be powered on and operate.

[0013] Furthermore, the diagnostic box has a light-transmitting area at one end near the pre-compression area for use with an auxiliary light-emitting plate. This design allows for better use with the auxiliary light-emitting plate, enabling the light from the plate to penetrate into the light-transmitting area. This optimizes the diagnostic process of screw fastening. When the light-emitting plate is powered on, it produces light that passes through the mounting base and the diagnostic box, reaching the light-transmitting area. When the product is placed on the surface of the pre-compression area, the light from the light-transmitting area illuminates the product, allowing the operator to visually observe the light transmission between the product and the screw holes. This helps determine if the screw holes are aligned with the fastening coordinates. Once the product is deemed satisfactory, a protective cover is pressed onto the surface of the product. Pressure is applied to the product by the protective cover and the pre-compression cotton to prevent the product from shifting during screw fastening, which could cause the screw to deviate from its track and break inside the product.

[0014] Furthermore, the diagnostic box has an internal connecting groove for accommodating the pre-compression area. This structure effectively accommodates the pre-compression area, facilitating diagnostic operations and improving diagnostic efficiency and accuracy. It also provides a buffer space for the pre-compression area, preventing damage from screw tightening pressure. Rubber rods for auxiliary buffering are installed at the bottom of the pre-compression area. These rubber rods reduce impact force, enhance buffering effect, and reduce damage caused by impact during pressure compression. The rubber rods are arranged in a matrix at the bottom of the pre-compression area. This structure provides uniform buffering, preventing tilting of the pre-compression area due to excessive local pressure or installation errors during screw tightening.

[0015] Furthermore, the surface of the diagnostic box is provided with heat dissipation grooves to assist the main control circuit board and the illumination board in heat dissipation; the heat dissipation grooves improve heat dissipation efficiency, reduce equipment temperature, and thus extend the service life of the equipment. In addition, by adding heat dissipation grooves, the equipment is prevented from overheating and causing performance degradation, thereby enhancing the stability and reliability of the equipment.

[0016] Compared with the prior art, the beneficial effects of this utility model are: the stainless steel guide sleeve, protective cover plate, pre-compression area and pre-compression cotton used for screw fastening protect the appearance of the product and avoid damage to the appearance of the product caused by the pressure generated during mold closing. After the product is initially fixed, this screw fastening fixture is placed on the worktable of the automatic screw machine so that the operator can carry out the screw fastening process.

[0017] This structure can be used in automatic screw fastening machines or manual screw fastening machines. It adopts a simplified structure to realize the processes of lighting, alignment and positioning. While assisting in screw fastening, it is easy for operators to operate and allows them to intuitively observe the light transmittance of the holes, avoiding blind holes or hole blockage. This prevents abnormal situations from occurring during the screw fastening process, which could cause the screw to deviate from the track and break inside the product. Attached Figure Description

Detailed Implementation

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0032] For this embodiment, please refer to Figures 1-12 The present invention relates to a screw-locking fixture for protecting the appearance of a product, comprising a protective cover plate 1, a diagnostic box 2, and a base plate 3. The diagnostic box 2 is installed between the protective cover plate 1 and the base plate 3. One end of the diagnostic box 2 is a pre-compression area 4. The surface of the pre-compression area 4 is connected with pre-compression cotton 5. The pre-compression cotton 5 and the pre-compression area 4 are separated. One end of the pre-compression cotton 5 is attached to one end of the protective cover plate 1. The main control circuit board 6 is installed inside the diagnostic box 2. The main control circuit board 6 is electrically connected to a light-illuminating plate 7. Both the main control circuit board 6 and the light-illuminating plate 7 are installed inside the diagnostic box 2 through a mounting base 8. The diagnostic box 2 is a light-transmitting structure, the mounting base 8 is a light-transmitting structure, the protective cover plate 1 is a light-transmitting acrylic plate, and the surface of the protective cover plate 1 is provided with several mounting holes 9. The inner surface of the mounting holes 9 is connected with a stainless steel guide sleeve 10 for auxiliary screw fastening.

[0033] This utility model protects the product's appearance by using a stainless steel guide sleeve 10, a protective cover plate 1, a pre-compression area 4, and pre-compression cotton 5 for screw fastening, preventing damage to the product's appearance caused by the pressure generated during mold closing. After the product is initially fixed, this screw-fastening fixture is placed on the worktable of an automatic screw machine to facilitate the screw fastening process for the operator. This structure can be used with automatic screw machines or manual screw fastening. It adopts a simplified structure to achieve the processes of lighting, alignment, and positioning, assisting in screw fastening while facilitating operator operation. It allows the operator to intuitively observe the light transmittance of the holes, avoiding blind holes or hole blockage, thereby preventing abnormal situations from occurring during the screw fastening process, which could cause the screw to deviate from its track and break inside the product.

[0034] An adjusting frame 11 is installed at one end of the base plate 3. An adjusting rod 12 is connected to the surface of the adjusting frame 11. The adjusting rod 12 is connected to the protective cover plate 1. The position of the protective cover plate 1 can be adjusted horizontally by twisting the adjusting rod 12. This setting increases the flexibility of the structure and makes it easier to adapt to the needs of different working environments. When the position of the diagnostic box 2 cannot be adjusted, the adjusting rod 12 can be twisted to move the protective cover plate 1 horizontally, so that the mounting hole 9 on the surface of the protective cover plate 1 and the stainless steel guide sleeve 10 are aligned with the hole inside the product that needs to be fastened. This achieves a flexible adjustment effect and avoids the product from shifting during the screw fastening process, which could cause the screw to deviate from the track and break inside the product.

[0035] The surface of the base plate 3 is provided with a limiting slot 13 for placing the diagnostic box 2, and the surface of the diagnostic box 2 is provided with a limiting block 14 for connecting screws to assist in limiting the position.

[0036] The limiting slot 13 on the surface of the base plate 3 cooperates with the limiting block 14 on the surface of the diagnostic box 2 to ensure that the diagnostic box is accurately placed on the base plate, which facilitates the connection of screws for fixing, improves the convenience and stability of assembly, and also reduces the possibility of misoperation. It also prevents the product from shifting during the screw fastening process, which could cause the screw to deviate from the track and break inside the product. When signs of shifting are found, the installation position of the limiting block 14 can be adjusted to place the diagnostic box 2 in the specified installation position, which is convenient for screw fastening. The size of the limiting slot 13 is larger than the size of the diagnostic box 2 to leave a margin for adjustment of the diagnostic box 2.

[0037] The main control circuit board 6 is electrically connected to a data interface 15 and a power socket 16, both of which extend to the surface of the diagnostic box 2. This structure facilitates quick connection and disconnection of data transmission and power by operators, improving operational convenience and maintenance efficiency. The data interface 15 enables data transmission and communication between devices, and uses an external display device for real-time monitoring to ensure the overall operation remains normal and stable, reducing the number of risk checks and the probability of accidents. The power socket 16 is used to connect an external power cord so that the main control circuit board 6 can be powered on for operation.

[0038] The diagnostic box 2 has a light-transmitting area 17 at one end near the pre-compression area 4 for use with the auxiliary light plate 7. This design allows for better use with the auxiliary light plate 7, enabling the light from the light plate 7 to penetrate into the light-transmitting area 17, thereby optimizing the diagnostic process of screw fastening. When the light plate 7 is connected to the power supply, it generates light, which passes through the mounting base 8 and the diagnostic box 2 in sequence, reaching the light-transmitting area 17. When the product is placed on the surface of the pre-compression area 4, the light transmitted through the light-transmitting area 17 illuminates the product, allowing the operator to visually observe the light transmission between the product and the screw holes. This allows the operator to determine whether the screw holes are aligned with the fastening coordinates. Once the product is deemed to be of good quality, the protective cover 1 is pressed onto the surface of the product. The pressure applied by the protective cover 1 and the pre-compression cotton 5 applies pressure to the product, preventing the product from shifting during the screw fastening process and causing the screw to deviate from its track and break inside the product.

[0039] The diagnostic box 2 has a connecting groove 18 inside to accommodate the pre-compression area 4. This structure can effectively accommodate the pre-compression area 4, facilitate diagnostic operations, and improve diagnostic efficiency and accuracy. At the same time, it provides a certain buffer space for the pre-compression area 4 to avoid damage to the pre-compression area 4 caused by the pressure during screw fastening. The bottom of the pre-compression area 4 is equipped with rubber soft rods 19 for auxiliary buffering. The rubber soft rods 19 can reduce impact force, enhance the buffering effect, and reduce the damage caused by the impact force during pressure pressing. The rubber soft rods 19 are arranged in a matrix at the bottom of the pre-compression area 4. This structure provides uniform buffering and avoids the pre-compression area 4 from tilting due to excessive local pressure or the installation error of screw fastening during pressing.

[0040] The surface of the diagnostic box 2 is provided with heat dissipation grooves 20 to assist the main control circuit board 6 and the light board 7 in heat dissipation. The heat dissipation grooves 20 improve heat dissipation efficiency, reduce equipment temperature, and thus extend the service life of the equipment. In addition, by adding heat dissipation grooves 20, the equipment is prevented from overheating and causing performance degradation, thereby enhancing the stability and reliability of the equipment.

[0041] The key design features of this utility model are: the stainless steel guide sleeve 10, protective cover plate 1, pre-compression area 4 and pre-compression cotton 5 used for screw fastening protect the appearance of the product and prevent the pressure generated during mold closing from damaging the appearance of the product. After the product is initially fixed, this screw fastening fixture is placed on the worktable of the automatic screw machine so that the operator can perform the screw fastening process.

[0042] This structure can be used in automatic screw fastening machines or manual screw fastening machines. It adopts a simplified structure to realize the processes of lighting, alignment and positioning. While assisting in screw fastening, it is easy for operators to operate and allows them to intuitively observe the light transmittance of the holes, avoiding blind holes or hole blockage. This prevents abnormal situations from occurring during the screw fastening process, which could cause the screw to deviate from the track and break inside the product.

[0043] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
