Description

Technical Field

[0001] This utility model belongs to the field of terminal block technology, and in particular relates to an automatic nut assembly device. Background Technology

[0002] Terminal blocks are components used in electrical engineering to connect, distribute, and manage wires. They are typically composed of insulating materials (such as plastic or nylon) and conductive metal sheets (such as copper alloys). They simplify circuit connections, improve wiring efficiency, and are common components in equipment such as distribution cabinets and control boxes.

[0003] Currently, most terminal blocks typically have multiple nuts installed and fixed on them. Bolts are used to thread the terminal blocks through these nuts, connecting them to equipment such as distribution cabinets or control boxes, thus enabling the terminal blocks to be installed and used in these devices. In existing technology, the installation process between the nuts and the terminal blocks usually involves drilling mounting holes in the terminal blocks and then manually gluing the nuts into the holes. This method requires a significant amount of manpower and time, resulting in low production efficiency. Utility Model Content

[0038] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] In the description of this application, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0040] Example 1:

[0041] This embodiment provides an automatic nut assembly device, including a workbench 1, a material transfer device 2, and an assembly device. The material transfer device 2 is mounted on the workbench 1 for transporting terminal blocks along the X direction. The assembly device includes:

[0042] The fixed frame 3 is installed on the workbench 1 and is located on one side of the material transfer device 2 along the Y direction;

[0043] The feeding mechanism 4 is mounted on the fixed frame 3 and is used to feed nuts to the terminal block on the feeding device 2 along the Z direction.

[0044] Heating mechanism 5 is mounted on the fixed frame 3 and connected to the output end of the unloading mechanism 4, and is used to heat the nuts.

[0045] The pressing mechanism 6 is movable along the Z direction and is mounted on the fixed frame 3 to press the nut onto the terminal block;

[0046] The pushing mechanism 7 is mounted on the fixed frame 3 and is used to push the nut processed by the heating mechanism 5 to the output end of the pressing mechanism 6.

[0047] In this technical solution, the material conveying device 2 can be composed of a feeding trough and a conveyor belt. The two ends of the feeding trough are respectively connected to a feeding vibrating plate and a storage tray (the feeding vibrating plate and the storage tray are not shown in the attached drawings of the specification). The feeding vibrating plate is used to convey the terminal block material to the feeding trough. The terminal block on the feeding trough is transported by the conveyor belt through the assembly device. The unloading mechanism 4 of the assembly device conveys nuts to the heating mechanism 5. After being heated by the heating mechanism 5, the nuts are pushed by the pushing mechanism 7 to the output end of the pressing mechanism 6. The pressing mechanism 6 presses the heated nuts downward along Z and presses them onto the terminal block. After the nuts are assembled, the terminal block is then transported by the conveyor belt to the storage tray for storage, completing the automatic nut assembly operation of the terminal block.

[0048] Furthermore, the feeding mechanism 4 includes:

[0049] The feeding vibratory plate is mounted on the fixed frame 3 and is used to sort and output nuts;

[0050] Feeding pipe 41 is located on the output end of the vibratory feeder and is connected to the heating mechanism 5.

[0051] Furthermore, the heating mechanism 5 includes:

[0052] Heating module 51 is mounted on the fixing frame 3 for heating nuts, and a material passage 54 is provided inside the heating module 51;

[0053] Feed pipe 52 is installed on heating module 51, and its two ends are respectively connected to feeding pipe 41 and material passage 54;

[0054] The discharge pipe 53 is installed on the heating module 51, and its two ends are connected to the material channel 54 and the terminal block, respectively.

[0055] Furthermore, the pusher mechanism 7 includes:

[0056] The pusher plate 71 is disposed in the material passage 54 of the heating module 51, which can be reciprocated along the Y direction.

[0057] The first driving component 72 is mounted on the fixed frame 3 and is used to drive the pusher plate 71 to move.

[0058] The pusher plate 71 has a storage hole 73. During the reciprocating movement of the pusher plate 71, the storage hole 73 moves back and forth between the feed pipe 52 and the discharge pipe 53.

[0059] The specific working steps of the assembly device are as follows: the feeding vibratory plate sorts and arranges the nuts to be installed and outputs them to the feeding pipe 41 through the hose. The nuts fall into the feeding pipe 52 through the feeding pipe 41, and then fall into the material passage 54 of the heating module 51 through the feeding pipe 52. The heating module 51 consists of a heat-conducting block and an electric heating wire. The material passage 54 is set inside the heat-conducting block. The electric heating wire is installed inside the heat-conducting block and is energized to heat the heat-conducting block, so that the nuts located in the material passage 54 are heated to a certain temperature. Then, the pushing mechanism 7 pushes the heated nuts to the discharge pipe 53. The nuts fall into the mounting holes of the terminal block through the discharge pipe 53. Finally, the pressing mechanism 6 moves along the Z direction to press the nuts in the mounting holes onto the terminal block.

[0060] In summary, this automatic nut assembly equipment can first heat-treat the nuts to be pressed, then transport the heated nuts to the terminal blocks, and then use the pressing mechanism 6 to heat-press the nuts onto the terminal blocks. This not only securely installs the nuts on the terminal blocks but also achieves automatic assembly, reducing manual labor and time consumption, effectively lowering production costs and improving production efficiency, resulting in higher economic benefits.

[0061] Example 2:

[0062] This embodiment provides an automatic nut assembly device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0063] Furthermore, the pusher mechanism 7 includes:

[0064] The pusher plate 71 is disposed in the material passage 54 of the heating module 51, which can be reciprocated along the Y direction.

[0065] The first driving component 72 is mounted on the fixed frame 3 and is used to drive the pusher plate 71 to move.

[0066] The pusher plate 71 has a storage hole 73. During the reciprocating movement of the pusher plate 71, the storage hole 73 moves back and forth between the feed pipe 52 and the discharge pipe 53.

[0067] In this technical solution, the first driving component 72 can be a cylinder. The storage hole 73 of the pusher plate 71 is initially connected to the feed pipe 52, allowing a nut inside the feed pipe 52 to fall into the storage hole 73. Then, the cylinder controls the pusher plate 71 to move within the material passage 54 of the heating module 51, keeping the storage hole 73 on the pusher plate 71 connected to the discharge pipe 53. This allows the nut in the storage hole 73 to fall into the discharge pipe 53 and then along the discharge pipe 53 into the mounting hole of the terminal block. Through the above structural design, the nuts are automatically and orderly output to the terminal block, resulting in high practicality.

[0068] Furthermore, the pusher mechanism 7 also includes:

[0069] First guide assembly 74, the first guide assembly 74 is mounted on the fixed frame 3 and is arranged along the Y direction;

[0070] The pusher plate 71 and the first drive component 72 are connected by the first guide component 74.

[0071] The first guide component 74 can be a slider guide rail structure. By setting the slider guide rail structure, the pusher plate 71 can be moved stably in the Y direction, so as to avoid the pusher plate 71 from deviating during the movement and getting stuck in the heating module 51.

[0072] Example 3:

[0073] This embodiment provides an automatic nut assembly device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0074] Furthermore, the pressing mechanism 6 includes:

[0075] A pressure rod 61 is movable along the Z-direction and is mounted on the heating module 51 to press the nut onto the terminal block;

[0076] The second driving component 62 is mounted on the fixed frame 3 and is used to control the movement of the pressure rod 61.

[0077] In this technical solution, the second driving component 62 can also be a cylinder. When performing the pressing operation, the second driving component 62 controls the pressing rod 61 to pass through the heating module 51 and the discharge pipe 53 in the Z direction, and then abut against the nut located on the terminal block to press the nut onto the terminal block.

[0078] Furthermore, the pressing mechanism 6 also includes:

[0079] The second guide assembly 63 is mounted on the fixed frame 3 and is arranged along the Z direction. The pressure rod 61 is connected to the fixed frame 3 through the second guide assembly 63.

[0080] The second guide component 63 can be a slider guide rail structure. By setting the slider guide rail structure, the movement of the pressure rod 61 is guided, making the downward pressing action of the pressure rod 61 more stable, avoiding collisions between the pressure rod 61 and the heating module 51 or the discharge pipe 53 and thus effectively improving production safety.

[0081] Example 4:

[0082] This embodiment provides an automatic nut assembly device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0083] Furthermore, it also includes a testing device 8, which is installed on the workbench 1 and located downstream of the assembly device, for testing terminal blocks.

[0084] In this technical solution, the detection device 8 can be a CCD camera. The wiring on the material transfer device 2 passes through the terminal block of the assembly device for photographic detection, ensuring that nuts are press-fitted into the mounting holes on the terminal block, thereby effectively reducing the defect rate and improving production quality.

[0085] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive.
