Technical Field
[0001] This utility model relates to the field of assembly fixture technology, specifically to a screw installation error-proof structure. Background Technology
[0002] In modern manufacturing, screws are a common type of fastener, widely used in the assembly and fixing of numerous workpieces. For example, in the manufacturing and maintenance of industrial machinery, such as machine tools and automated equipment, various types of screws are required to ensure the reliability and stability of the mechanical structure.
[0003] However, current screw installation technology has obvious defects and shortcomings. With the diversification and complexity of products, there are many types of screws used, including different thread specifications, lengths, head shapes, and materials. The corresponding screw holes also exhibit diverse characteristics. In actual operation, due to the diversity of screws and screw holes, it is very easy to install screws incorrectly. Such incorrect installation may lead to weak workpiece connections, affecting the overall performance and quality of the product. Once a screw installation error occurs, it often requires additional time and manpower for rework, disassembly, and reinstallation, which greatly reduces production efficiency and is not conducive to the intelligent development of the production process.
[0004] Therefore, there is an urgent need for a foolproof structure that can effectively solve the problem of screw installation errors, so as to improve the accuracy and reliability of screw installation, and improve production efficiency and product quality; in view of this, we propose a screw installation foolproof structure.

[0030] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0031] Please see Figure 1-4 The present invention will describe the above technical solution in detail through the following embodiments:
[0032] A screw-mounting foolproof structure, including as follows Figure 1 The platform 5 shown also includes:
[0033] Screw placement component 2, such as Figure 1 and Figure 3 The structure shown includes a support base 21 mounted on a support platform 5, and a placement tray 25 for supporting screw bodies 4. It should be noted that, in this embodiment, to prevent accidental removal of different screws, a movable plate 24 is mounted on the support base 21 via a scissor-type connecting frame 22. A movement cylinder 23 is mounted on the movable plate 24 to drive the opening and closing of the scissor-type connecting frame 22. The scissor-type connecting frame 22 moves the movable plate 24 via the movement cylinder 23. In this embodiment, an outer cover is installed on the movable plate 24 to cover the placement tray 25, effectively placing and storing the screw bodies 4. In this embodiment, the tray 25 has insertion holes for regularly inserting the screw bodies 4 to be installed. According to the installation sequence, the corresponding screw bodies 4 are placed one by one into the flip-up adsorption seat 35, which provides a fixed retrieval point.
[0034] This embodiment is as follows: Figure 1A screw fastening assembly 3 is provided at the location, specifically including a base plate 31 on which a PLC control module 34 and a solenoid valve 33 are installed. The base plate 31 is mounted on the support platform 5. In this embodiment, a product carrier plate 32 for supporting the product to be assembled and a flip-type adsorption seat 35 for adsorbing the screw body 4 are installed on the base plate 31. It should be noted that in this embodiment, the function of the flip-type adsorption seat 35 is to magnetically adsorb the screw body 4 into a position as shown. Figure 1 and Figure 4 As shown, the flip-up adsorption seat 35 is equipped with an electromagnetic suction block, which has a vertical groove for magnetically attracting the screw body 4. The screw body 4 can be quickly adjusted to a vertical state. The electromagnetic suction block rotates through the drive motor, adjusting its nut head to face upwards, making it easy for the screwdriver bit fixing clamp arm 16 to pick it up.
[0035] like Figure 1 and Figure 2 As shown, the bit fixing assembly 1 includes a vertical rod 11 fixedly installed on the support 5. In this embodiment, the vertical rod 11 is rotatably installed on the support 5 through a flange fixing seat 13. A buffer 12 is installed on the vertical rod 11 to make the rod rotate smoothly. The vertical rod 11 rotates under the drive of the motor and can be stopped stably with the help of the buffer 12, so as to align the screw body 4.
[0036] It should be noted that, in order to achieve the lifting function and facilitate better handling of the screw body 4, a horizontal bar 17 is installed at the top of the vertical bar 11, and a main arm 14 is slidably installed on the vertical bar 11. A balancer 18 is installed between the horizontal bar 17 and the main arm 14. The balancer 18 can drive the main arm 14 to lift and lower in the vertical direction, thereby facilitating adjustment to the position aligned with the height of the end of the screw body 4. One end of the main arm 14 is rotatably mounted with a bit fixing clamp 16 via a support arm 15. The bit fixing clamp 16 has a bit groove 161. In this embodiment, micro motors are installed at the connection points of the support arm 15, the main arm 14, and the bit fixing clamp 16. The position of the bit groove 161 can be changed by rotation. In order to accurately engage the screw body 4, the bit groove 161 in this embodiment can magnetically attract the screw body 4, which is consistent with the principle of current magnetic screwdrivers. This part is a mature technology, so it will not be explained in detail.
[0037] The screw installation error prevention structure of this embodiment works as follows: the required screw body 4 is placed on the screw placement component 2, and the screw body 4 is magnetically attracted by the flip-up adsorption seat 35. The screw body 4 is aligned with the bit fixing component 1 so that the screw body 4 is picked up to the bit groove 161. After aligning with the screw hole of the product to be installed, the screw body 4 is placed in for installation.
[0038] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.
[0039] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.
[0040] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
