Description

Technical Field

[0001] This utility model relates to the field of automated identification devices for material conveying systems, specifically to a mechanism for rapid identification and switching of material types within a material frame in the automotive manufacturing industry when multiple models are produced on the same production line, and is particularly suitable for a flexible material frame identification system for car door assembly lines. Background Technology

[0002] In recent years, with the diversified development of the new energy vehicle market, the need for automobile manufacturing production lines to adapt to the co-production of multiple models has become increasingly urgent. Against this backdrop, the application of shared material frames for multiple vehicle models in flexible production lines has become a key element, requiring them to support different models of doors and achieve rapid identification.

[0003] Existing material frame recognition mechanisms mainly rely on two types of contact switch solutions: 1) Bolt and nut adjustment type: The position of the bolt head contact is adjusted by tightening / loosening the nut, but the bolt length needs to be readjusted each time to ensure sensing accuracy, which is cumbersome and inefficient; 2) Bracket assembly type: The bracket with contact is fixed with bolts, and the bolts need to be repeatedly disassembled and reassembled with tools when switching, which results in wasted time and reliance on manual labor.

[0004] The aforementioned solutions, due to the need for repeated debugging and complex disassembly / reassembly operations during the switching process, are insufficient to meet the rapid switching requirements of high-cycle production lines. Therefore, there is an urgent need for an identifiable mechanism capable of rapidly switching material frames across multiple vehicle models to improve the response efficiency of flexible production. Utility Model Content

[0005] The purpose of this invention is to provide a fast-switching material frame identification mechanism, which aims to overcome the shortcomings of the prior art and solve the problems of low material type identification efficiency and cumbersome switching in multi-vehicle production lines.

[0006] Therefore, this utility model proposes a rapidly switching material frame identification mechanism, comprising:

[0007] The base is fixed to both sides of the front end of the material frame and has at least two positioning slots extending in the vertical direction.

[0008] At least two sets of quick-plug components, each set including:

[0009] A quick-release block, which is detachably inserted into any of the positioning slots;

[0010] The induction stud plate is threadedly connected to the quick-release block;

[0011] The locking nut is fitted onto the stud of the induction stud plate and abuts against the side of the quick-release block;

[0012] The material receiving mechanism located on one side of the material frame is equipped with a contact switch corresponding to the position of the sensing stud plate; multiple sets of quick-release components are inserted and removed in the positioning slot to form a multi-digit code, and the contact switch determines the type of material in the material frame by recognizing the position of the sensing stud plate.

[0013] As a preferred technical solution of this application, the lower end of the quick-plug block is provided with a positioning post and an anti-dislodgement mechanism, and the base is provided with a positioning hole associated with the positioning slot, and the positioning post cooperates with the positioning hole.

[0014] As a preferred technical solution of this application, the anti-detachment mechanism is a spring-top ball structure, including a radial circular hole on the positioning post, a spring installed in the circular hole, and top balls symmetrically arranged at both ends of the spring. The top balls abut against the side wall of the positioning hole under the action of the spring force.

[0015] As a preferred technical solution of this application, the anti-detachment mechanism can be replaced by a through-hole insertion pin or a pin structure.

[0016] As a preferred technical solution of this application, the positioning holes of the base correspond one-to-one with the positioning slots, and the shape of the positioning holes matches the positioning posts.

[0017] As a preferred technical solution of this application, the base is provided with three positioning slots extending in the vertical direction; correspondingly, three sets of quick-plug components are installed.

[0018] As a preferred technical solution of this application, the side of the quick-plug block is provided with multiple countersunk holes, and the flat-head screw passes through the countersunk holes and is detachably fixed to the side wall of the material frame.

[0019] As a preferred technical solution of this application, two sets of material frame identification mechanisms are symmetrically arranged on the left and right sides of the front end of the material frame, and the material receiving mechanism is provided with multi-contact identification switches corresponding to the two sets of components.

[0020] As a preferred technical solution of this application, the locking nut is threadedly connected to the induction stud disk and presses against the side of the quick-release block to lock the axial position of the induction stud disk.

[0021] As a preferred technical solution of this application, the induction stud disk can be replaced with a bolt with adjustable length.

[0022] The quick-switching material frame identification mechanism provided by this utility model has the following advantages: 1) In order to realize the identification of material conditions in the warehouse when multiple vehicle models share the same material frame, multiple points and multiple combination of sensing points are used to identify the vehicle model; 2) It does not require repeated disassembly and assembly, and does not require repeated adjustment of the position of the sensing points; 3) It has a simple structure, small overall size, and is easy to use.

[0031] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] like Figures 1-5 As shown, the quick-switching material frame identification mechanism of this utility model is installed on the left and right sides of the front end of the material frame 6; a pair of multi-contact identification switch mechanisms are installed on the corresponding material receiving mechanism. The material frame identification mechanism mainly includes: a base 1 and at least two sets of quick-plug components. By adding multiple quick-plug components to the front end of the material frame 6, multiple combinations form a multi-digit code, realizing the identification of material conditions for various vehicle models. By quickly switching the quick-plug sensing block, the quick switching of different vehicle models can be achieved.

[0033] Each quick-plug assembly includes a quick-plug block 2, an induction stud plate 3, a locking nut 4, and a flat-head screw 5. The base 1 is fixed to both sides of the material frame 6 using the flat-head screw 5. Then, the quick-plug block 2 is inserted into the positioning slot 11 of the base 1. The locking nut 4 is then installed on the induction stud plate 3, and the locking nut 4 and the induction stud plate 3 are locked together in the quick-plug block 2.

[0034] The two sets of quick-plug components can form three contact modes: (1,0), (0,1), and (1,1). Different types of materials are loaded on the material frame 6, corresponding to different contact modes. The multiple contact switches on the material receiving mechanism can identify the position of the sensing stud plate 3, and thus determine the type of material loaded on the material frame 6.

[0035] Specifically, the base 1 is a rectangular block structure with three vertically extending positioning slots 11, each corresponding to a set of quick-release components. The shape of the positioning slots 11 matches the shape of the quick-release block 2. The quick-release block 2 has a protruding positioning post 23 at its lower end, and similarly, the base 1 has positioning holes 12 that match the positioning post 23. The three positioning slots 11 on the base 1 can form various contact patterns such as (1,0,0), (1,1,0), (1,1,1), (0,1,0), (0,1,1), and (0,0,1). The multiple contact switches on the material receiving mechanism can identify the position of the sensing stud plate 3, thereby determining the type of loading door on the material frame 6.

[0036] like Figure 4 As shown, to prevent the quick-release block 2 from falling off, a spring-loaded ball mechanism is provided on the positioning post 23 to form an anti-dislodgement mechanism. Specifically, a radial circular hole perpendicular to its axis is formed on the positioning post 23, with a spring 21 installed in the center of the hole and a ball 22 installed at each end. When the positioning post 23 engages with the positioning hole 12 on the base 1, the spring force of the spring 21 pushes the ball 22 outwards, making it tightly contact the sidewall of the positioning hole 12. The positioning hole 12 of the base 1 corresponds one-to-one with the positioning slot 11, and the shape of the positioning hole 12 matches that of the positioning post 23.

[0037] Meanwhile, the induction stud disk 3 is composed of a disk and a stud, and the quick-release block 2 is provided with an internal thread that matches the stud. The two are threadedly connected and can be adjusted to the front and rear positions, making it easy to be identified by the contact switch on the material receiving mechanism. In order to prevent the induction stud disk 3 from becoming loose, a locking nut 4 is provided on the stud. The locking nut 4 is threadedly connected to the stud, and one end of it abuts against the side of the quick-release block 2 to achieve a fastening effect.

[0038] like Figure 5As shown, the quick-plug block 2 has multiple countersunk holes on its side, and the flat-head screws 5 pass through the countersunk holes and are detachably fixed to the side wall of the material frame 6. Each material frame 6 requires two sets of the identifiable mechanisms described in this application, which are placed on the left and right sides of its front end; a pair of multi-contact identification switch mechanisms are installed on the corresponding material receiving mechanism.

[0039] It should be noted that other structures can also be used to achieve the corresponding functions of this application, as follows: 1. The spring-loaded ball mechanism in the quick-release block of this invention can be replaced with a through-hole insertion pin, a locking pin, etc., which can also achieve the fastening of the quick-release block 2 and prevent it from falling off, and falls within the protection scope of this invention. 2. The induction stud plate in this invention can be replaced with a threaded mechanism such as bolts of different lengths, which can also achieve the adjustment of the bolt length to ensure that the sensing point is reached, and also falls within the protection scope of this invention.

[0040] The working principle and process of the quick-switching material frame recognition mechanism of this utility model are briefly described below.

[0041] For initial use, push the material frame into the storage position, adjust the position of the locking nut 4, confirm the position of the sensing stud plate 3, and secure it with the locking nut 4. No further adjustments will be needed afterward. Later, when installing car doors into the material frame along the four-door assembly line, first confirm which slot the material frame sensing mechanism is inserted into, ensuring it is inserted into the corresponding marked slot. If it is not the current car model, remove the sensing mechanism and insert it into the corresponding car model slot. Once the material frame is full, the material frame carrying the parts is transported to the storage position by the AGV. The material frame will be sensed by the storage position sensor and placed into the sensing mechanism in the current car model slot. The sensing result will then be transmitted to the PLC to complete the overall operation.

[0042] This invention enables rapid switching when multiple vehicle models share a material frame; it can also quickly identify the vehicle model in the current material frame based on the location of the plug-in block.

[0043] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
