Description

Technical Field

[0001] This utility model relates to the field of waste recycling and reuse technology, and in particular to a U-shaped snap fastener joining machine. Background Technology

[0002] U-shaped snap fastener joining machine is a specialized device that uses mechanical or automated means to quickly fix U-shaped snap fasteners onto workpieces. It has advantages such as high efficiency, simplicity, reliability, and low cost, and is widely used in automobile manufacturing, furniture, electronics, construction, packaging and other fields, enabling the rapid connection and disassembly of workpieces.

[0003] U-shaped snap fastener joining machines are generally composed of a frame, base, snap fastener feeding mechanism, and pressing execution mechanism. The main components of the U-shaped snap fastener joining machine are the frame and base, snap fastener feeding mechanism, pressing execution mechanism, workpiece positioning and clamping mechanism, control device (automatic model), and auxiliary devices. The working principle is as follows: the feeding mechanism transports the snap fasteners to the workstation in an orderly manner, the workpiece is fixed by the positioning and clamping mechanism, and the pressing execution mechanism (pneumatic / electric / manual drive) drives the mold to press the snap fastener into the preset position of the workpiece. The connection is achieved by utilizing the elastic deformation of the snap fastener or structural interlocking. The automated model achieves precise control by coordinating the various links through PLC and sensors.

[0004] Existing U-shaped snap-fit ​​machines cannot adjust the length of the control lever according to different situations, making it difficult to match the height, arm length, and workstation layout of different operators. This can easily lead to operator fatigue, affect efficiency, and result in a poor user experience. Fixed lengths can cause time-consuming adjustments to the operator's position or increase labor intensity due to lever arm issues, affecting pressing accuracy. The equipment also lacks compatibility. When changing snaps or workpiece specifications, the equipment needs to be modified due to incompatibility with mold height or motion interference, increasing maintenance costs and safety hazards. Operators may face risks due to improper posture, and automatic models may also malfunction due to component wear. Therefore, a new U-shaped snap-fit ​​machine is proposed to solve the above problems. Utility Model Content

[0024] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0025] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a U-shaped snap-fit ​​machine. A snap-fit ​​mechanism 2 is fixedly connected to the top of a base plate 1. The snap-fit ​​mechanism 2 can precisely press the U-shaped snaps together to achieve rapid connection with the workpiece. The snap-fit ​​mechanism 2 includes a fixing block 21 whose bottom is fixedly connected to the top of the base plate 1. The fixing block 21 is used to support and fix the parts of the snap-fit ​​mechanism 2 to ensure the stability of the overall structure. A storage box 23 is fixedly connected to the outside of the fixing block 21. The storage box 23 can store the U-shaped snaps to be used, which is convenient for picking up, putting down and replenishing. A frame 22 is fixedly connected to the outside of the storage box 23. The frame 22 provides external support for the storage box 23 and can also play a certain guiding and protective role in the snap-fit ​​pressing process.

[0026] A control mechanism 3 is rotatably connected to the outer side of the snap-fit ​​engagement mechanism 2 fixedly connected to the top of the base plate 1. The control mechanism 3 can adjust the working state or position of the snap-fit ​​engagement mechanism 2. The control mechanism 3 includes a connecting plate 31, the inner side of which is fixedly connected to the outer side of the base plate 1. The connecting plate 31 serves as the connection hub between the control mechanism 3 and the base plate 1, ensuring the stable transmission of control actions. A connecting rod 32 is fixedly connected to the outer side of the connecting plate 31. The connecting rod 32 is used to transmit control signals or power to realize the operation of the snap-fit ​​engagement mechanism 2. A sliding rod 34 is slidably connected inside the connecting rod 32. The sliding rod 34 can slide and extend within the connecting rod 32, thereby adjusting the working distance or position of the control mechanism 3. A limiting groove 35 is provided on the outer side of the sliding rod 34. The limiting groove 35 cooperates with the limiting component 33 to lock the position of the sliding rod 34, ensuring the stability of the adjusted state. A limiting component 33 is fixedly connected to the outer side of the connecting rod 32. The limiting component 33 is used to limit the movement of the sliding rod 34, thereby fixing the position of the control mechanism 3.

[0027] The limiting component 33 includes a limiting shell 331, which is fixed to the outside of the connecting rod 32 and provides a space for the internal rotating parts. A rotating disk 332 is rotatably connected inside the limiting shell 331. The rotating disk 332 can rotate inside the limiting shell 331 and control the position of the limiting arc 333 by rotating. The limiting arc 333 is fixedly connected to the outside of the rotating disk 332. The limiting arc 333 rotates with the rotating disk 332 and can be inserted into or disengaged from the limiting groove 35 on the outside of the sliding rod 34, thereby locking or unlocking the sliding rod 34.

[0028] Reference Figures 1 to 3 The base plate 1 has an internal sliding connection to an installation mechanism 4. The installation mechanism 4 can realize the quick installation and disassembly between the base plate 1 and the pre-embedded shell 47, improving the flexibility and applicability of the equipment. The installation mechanism 4 includes a shell 41. The outer side of the shell 41 is slidably connected to the inside of the base plate 1. The shell 41 can slide up and down inside the base plate 1 to realize docking and separation with the pre-embedded shell 47.

[0029] An extrusion rod 42 is slidably connected inside the outer casing 41. The extrusion rod 42 can move up and down inside the outer casing 41. The movement controls the extension and retraction of the limiting plate 44. A second spring 45 is fixedly connected to the bottom of the extrusion rod 42. The other end of the second spring 45 is fixedly connected to the inside of the outer casing 41. The second spring 45 provides a reset force for the extrusion rod 42, ensuring that the extrusion rod 42 maintains its initial position when it is not subjected to external force. Multiple limiting plates 44 are rotatably connected to the outside of the extrusion rod 42. The limiting plates 44 can rotate around the extrusion rod 42. The rotation enables engagement or disengagement with the slot of the pre-embedded shell 47.

[0030] A spring 43 is fixedly connected to the inner side of the limiting plate 44. The other end of the spring 43 is fixedly connected to the outer side of the compression rod 42. The spring 43 provides an outward elastic force to the limiting plate 44, so that the limiting plate 44 automatically pops out and engages when it reaches the slot of the embedded shell 47. A limiting ring 46 is fixedly connected to the outer side of the outer shell 41. The bottom of the limiting ring 46 is slidably connected to the top of the base plate 1. The limiting ring 46 can limit the position of the base plate 1 and ensure that the base plate 1 is accurately positioned during installation. An embedded shell 47 is slidably connected to the outer side of the outer shell 41. The embedded shell 47 is fixed in a designated position to provide an installation reference for the base plate 1. The top of the embedded shell 47 is slidably connected to the bottom of the base plate 1. Multiple slots are provided inside the embedded shell 47. The outer side of the limiting plate 44 is slidably connected to the inside of the slots. The fixed connection between the base plate 1 and the embedded shell 47 is achieved by the engagement of the limiting plate 44 with the slots.

[0031] Working principle: When the operator needs to use the snap-fit ​​machine, the pre-embedded shell 47 is first installed in the designated position. Then, the base plate 1 is placed on top of the pre-embedded shell 47. The outer shell 41 can then be slid into the interior of the pre-embedded shell 47. At this time, the multiple limiting plates 44 inside the outer shell 41 will be squeezed into the interior of the outer shell 41 by the inner wall of the pre-embedded shell 47. The pre-embedded shell 47 has a slot. When the limiting plate 44 slides into the slot, it will be pushed out of the interior of the outer shell 41 by the spring 43, so that the limiting plate 44 is pressed against the interior of the slot. Then, the limiting ring 46 can be pressed against the top of the base plate 1, thus restricting the base plate 1 to the top of the pre-embedded shell 47, thereby completing the fixation of the base plate 1. When it is necessary to move the base plate 1, the pressing rod 42 can be pressed down, so that the pressing rod 42 moves the multiple limiting plates 44 downward at once, so that the limiting plates 44 are squeezed to the outside of the pressing rod 42 by the inner wall of the outer shell 41. At this time, the limiting plates 44 can be disengaged from the interior of the slot.

[0032] After the base plate 1 is installed, the rotating disk 332 can be rotated by the handle connected to the outside of the rotating disk 332. At this time, the rotating disk 332 can drive the outer limiting arc 333 together, so that the limiting arc 333 can be disengaged from the inside of the limiting groove 35. Then the sliding rod 34 can be pulled upward, so that the length of the connecting rod 32 can be adjusted. After adjusting to a suitable length, the rotating disk 332 can be rotated again, so that the limiting arc 333 rotates back into the inside of the limiting groove 35, thereby limiting the sliding rod 34 to the specified length.

[0033] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
