Description

Technical Field

[0001] This utility model relates to the field of sign assembly technology, and in particular to a three-pitch shift fork mechanism for sign assembly. Background Technology

[0002] Signage assembly is the process of attaching signs to products, equipment, or carriers, and it is widely used in tools, electronic products, furniture, construction, and other fields.

[0003] However, in the current technology, the assembly of screwdriver labels is mainly done manually. This not only results in low overall work efficiency, making it difficult to meet the pace requirements of mass production, but also places a high degree of dependence on operators. Long-term operation can easily lead to fatigue and increase the probability of human error. At the same time, since the assembly process requires manual alignment and pressing, it is easy to cause hand cuts or crushing and other safety hazards, posing a significant operational risk. In addition, this manual assembly method has poor adaptability to the relative position and spacing between materials, and it is difficult to automatically adjust according to different models or specifications of products. This results in poor equipment versatility and insufficient production flexibility, which is not conducive to the intelligent production needs of multi-variety, small-batch production. Utility Model Content

[0004] The purpose of this invention is to solve the problem that manual assembly in the existing technology not only has low overall work efficiency but also makes it difficult to meet the pace requirements of mass production. Therefore, a three-pitch shift fork mechanism for sign assembly is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a three-pitch shift fork mechanism for sign assembly, including a support frame and a workbench fixedly connected to its top, a transplanting component is installed on one side of the top of the workbench, the transplanting component is drivenly connected to a shift fork component, and a pitch-changing mechanism is installed on the top of the shift fork component.

[0006] The pitch-changing mechanism includes a drive plate with a drive hole on its surface. A force-bearing block is slidably connected to the inside of the drive hole. A pitch-changing plate is fixedly connected to the bottom of the force-bearing block. A slide rail is slidably connected to the bottom of the pitch-changing plate. A cylinder is connected to one side of the drive plate and is mounted above the shift fork assembly. A connecting mechanism is installed at the bottom of the pitch-changing plate, and a shift fork plate is installed on one side of the connecting mechanism.

[0007] Preferably, a cover plate assembly is installed on one side of the top of the workbench, and a cover plate cylinder is driven to the output end of the cover plate assembly.

[0008] Preferably, the side wall of the variable pitch plate has a plug hole, and the top side wall of the shift fork plate is fixedly connected to a plug rod.

[0009] Preferably, one end of the plug rod is plugged into the plug hole, and the top of the shift fork plate is provided with a plug groove.

[0010] Preferably, the connecting mechanism includes a fixed frame, a slide rod is fixedly connected to the inner side of the fixed frame, and two plug-in blocks are symmetrically slidably connected to the surface of the slide rod.

[0011] Preferably, a spring is provided between the two plug blocks, and the spring is sleeved on the surface of the slide rod.

[0012] Preferably, one end of the plug block is plugged into the plug slot, and the other end of the plug block is fixedly connected to a drive block.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, the shift fork assembly drives the pitch-changing mechanism and the shift fork plate to move synchronously, so as to achieve precise gripping and stable transfer of materials, and ensure the continuity and reliability of the assembly process. The cylinder pushes the drive plate, which drives the force block and the pitch-changing plate to move in coordination, thereby realizing the synchronous adjustment of the parallel displacement and spacing of multiple shift fork plates to adapt to the clamping requirements of materials of different specifications. The whole mechanism is simple in design and flexible in adjustment. There is no need to adjust each shift fork plate individually, which greatly improves the adaptability, positioning accuracy and operation efficiency of the clamping mechanism, and is suitable for high-efficiency production scenarios of multi-variety automated assembly.

[0015] 2. In this utility model, the initial alignment is achieved through the insertion rod and the insertion hole. Combined with the cooperation of the insertion groove and the elastic insertion block, the stability and precise positioning of the shift fork plate are ensured during the installation process, preventing shaking or misalignment during operation. When disassembling, the drive block pushes the insertion block to move in the opposite direction along the slide rod, achieving quick release and separation, which facilitates the maintenance and replacement of the shift fork plate. The overall design is simple and efficient, which not only ensures the reliable installation of the shift fork plate, but also significantly improves the convenience and efficiency of maintenance operations. It is suitable for high-frequency disassembly and assembly scenarios with high precision requirements. Attached Figure Description

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figure 1-4 As shown, this utility model provides a three-pitch shift fork mechanism for sign assembly, including a support frame 1 and a workbench 2 fixedly connected to its top. A transplanting component 3 is installed on one side of the top of the workbench 2. The transplanting component 3 is drivenly connected to a shift fork component 7. A pitch-changing mechanism 4 is installed on the top of the shift fork component 7.

[0024] The pitch-changing mechanism 4 includes a drive plate 41, a drive hole 42 is provided on the surface of the drive plate 41, a force block 44 is slidably connected to the inside of the drive hole 42, a pitch-changing plate 43 is fixedly connected to the bottom of the force block 44, a slide rail 46 is slidably connected to the bottom of the pitch-changing plate 43, a cylinder 45 is connected to one side of the drive plate 41, the cylinder 45 is installed above the shift fork assembly 7, a connecting mechanism 9 is installed at the bottom of the pitch-changing plate 43, and a shift fork plate 5 is installed on one side of the connecting mechanism 9.

[0025] A cover plate assembly 8 is installed on one side of the top of the workbench 2, and a cover plate cylinder 6 is connected to the output end of the cover plate assembly 8.

[0026] The specific settings and functions of this embodiment are described below. During assembly, the shift fork assembly 7, as the core drive mechanism, can drive the entire pitch-changing mechanism 4 and the shift fork plate 5 to move synchronously. During its movement, the shift fork plate 5 inserts into the designated positioning hole or slot of the material, thereby achieving precise gripping and clamping of the material. This clamping action not only ensures the stability of the material during movement but also lays the foundation for subsequent transfer and assembly. After the shift fork plate 5 completes clamping, the transfer assembly 3 drives the shift fork assembly 7 to move as a whole, accurately transferring the clamped material from the loading area to the designated assembly station, providing an efficient and stable material transfer path for the automated assembly process.

[0027] To accommodate different types or specifications of materials and ensure that the shift fork 5 can be accurately aligned and inserted into the corresponding mounting holes during clamping, a cylinder 45 can drive the drive plate 41 to move linearly. Multiple drive holes 42 are provided on the surface of the drive plate 41. When the drive plate 41 moves, the drive holes 42 apply force to the multiple force-bearing blocks 44 connected to it, causing them to shift synchronously. The force-bearing blocks 44 then drive the variable-pitch plate 43 connected to them to move. The variable-pitch plate 43 is mounted on a slide rail 46 and can slide smoothly along the slide rail 46. During the movement of the variable-pitch plate 43, multiple shift forks 5 move simultaneously in conjunction, maintaining a consistent relative distance, thus achieving parallel displacement of the entire shift fork 5.

[0028] Regardless of how the spacing between materials changes, all shift forks 5 can be adjusted synchronously through a single action of the drive plate 41, eliminating the need for individual adjustment and effectively improving adjustment efficiency and positioning accuracy.

[0029] Example 2: Figure 1 and Figure 2 As shown, the variable pitch plate 43 has a plug-in hole 431 on its side wall, and a plug-in rod 51 is fixedly connected to the top side wall of the shift fork plate 5. One end of the plug-in rod 51 is plugged into the plug-in hole 431, and a plug-in groove 52 is provided at the top of the shift fork plate 5. The connecting mechanism 9 includes a fixed frame 91, and a slide rod 93 is fixedly connected to the inner side of the fixed frame 91. Two plug-in blocks 95 are symmetrically slidably connected to the surface of the slide rod 93. A spring 92 is provided between the two plug-in blocks 95, and the spring 92 is sleeved on the surface of the slide rod 93. One end of the plug-in block 95 is plugged into the plug-in groove 52, and a drive block 94 is fixedly connected to the other end of the plug-in block 95.

[0030] The overall effect of this embodiment is that, during the assembly and installation of the shift fork 5, the insertion rod 51 on one side of the top of the shift fork 5 is first inserted into the insertion hole 431 on the pitch plate 43 to achieve initial alignment. Simultaneously, the insertion groove 52 on the shift fork 5 is inserted into two insertion blocks 95 mounted on the fixed structure. During this insertion process, the insertion blocks 95, under the elastic action of the spring 92, tend to move along the surface of the slide rod 93, allowing one end of the insertion block 95 to reliably embed into the inner sidewall of the insertion groove 52, thus achieving stable positioning and limiting of the shift fork 5 and preventing it from shaking or misaligning during subsequent operation.

[0031] To disassemble or replace the shift fork 5, two drive blocks 94 can be moved closer together via a control device when necessary. During movement, the drive blocks 94 apply a pushing force to the insertion block 95, causing it to move in the opposite direction of the slide bar 93, thus gradually disengaging it from the insertion slot 52. Once the insertion block 95 is completely out of the insertion slot 52, the shift fork 5 can be loosened and easily disassembled, facilitating maintenance, replacement, or adjustment. This structural design not only ensures the stable installation of the shift fork 5 but also improves the convenience and efficiency of subsequent maintenance.

[0032] The operating method and working principle of this device are as follows: During assembly, the shift fork assembly 7 drives the entire pitch-changing mechanism 4 and the shift fork plate 5 to move synchronously, allowing the shift fork plate 5 to insert into the material, thereby clamping and moving the material. Subsequently, the shift fork assembly 7 is moved by the transfer assembly 3, so that the clamped material is moved to the assembly station, completing the transfer process.

[0033] To accommodate materials of different specifications and ensure accurate insertion of the shift fork 5, a cylinder 45 can be used to move the drive plate 41. During movement, the drive plate 41 applies force to multiple force-bearing blocks 44 through drive holes 42 on its surface, causing the force-bearing blocks 44 to move the pitch-changing plate 43. The pitch-changing plate 43 slides on the slide rail 46, thereby driving multiple shift fork 5 to move synchronously and maintaining consistent spacing between them. This satisfies the need for adaptability to materials with different spacing while ensuring assembly accuracy.

[0034] During the installation of the shift fork 5, first insert the connecting rod 51 on one side of the top of the shift fork 5 into the connecting hole 431, and simultaneously align the connecting groove 52 with the two connecting blocks 95. With the help of the spring force of the spring 92, the connecting blocks 95 are pushed as they slide on the surface of the slide rod 93, causing one end to embed into the inside of the connecting groove 52, thus positioning the shift fork 5. When the two drive blocks 94 approach each other, they can drive the two connecting blocks 95 out of the connecting groove 52, thereby facilitating the disassembly and replacement of the shift fork 5.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
