Description

Technical Field

[0001] This utility model relates to the field of dispensing technology, and in particular to a dispensing device for a junction box. Background Technology

[0002] Junction boxes are widely used accessories in electrical installations, primarily for protecting the connection points of electrical wires. During circuit wiring, junction boxes are used when wires need to be connected, branched, or have their routes changed. They enclose these connection points, preventing accidental contact with live parts and thus electric shock, providing safety protection. Junction boxes also protect connection points from external environmental factors (such as moisture, dust, and corrosive gases), ensuring the reliability of the connection and the stability of the circuit. Generally, a junction box consists of two parts: a body and a cover. The body is typically a plastic or metal container with sufficient space to accommodate wire connectors and related electrical connection components. Inside the junction box are terminals for securing the wires. To ensure a more reliable connection between the wires and the terminals, adhesive is typically applied to the inside of the junction box and at the connection point between the body and the cover. During adhesive application, a manual caulking gun is used to apply adhesive to multiple locations on the product. After application, the cover is manually pressed down to ensure it is securely in place. On the one hand, manual dispensing of adhesive can easily lead to fatigue. On the other hand, the long interval between manually dispensing adhesive and manually pressing the cap can cause the adhesive to cure prematurely. Moreover, it is difficult to accurately control the amount of adhesive dispensed manually, and it is easy to dispense adhesive beyond the process range. Utility Model Content

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0030] See Figures 1 to 5 The figure shows an embodiment of the dispensing equipment for the junction box provided by this utility model.

[0031] Junction box 1 includes a box body 11 and a box cover 12. The box cover 12 is foldable and connected to the box body 11. The box cover 12 has a first state, a second state and a third state. When the box cover 12 is in the first state, the opening angle of the box cover 12 is greater than 90 degrees and less than 180 degrees. When the box cover 12 is in the second state, the opening angle of the box cover 12 is less than 90 degrees. When the box cover 12 is in the third state, the box cover 12 is snapped and connected to the box body 11.

[0032] Dispensing equipment includes:

[0033] Workbench 2 is equipped with dispensing equipment;

[0034] The loading and unloading mechanism 3 is used to drive the junction box 1 to move along the horizontal X-axis so that the junction box 1 arrives at and leaves the above-mentioned dispensing station;

[0035] The dispensing mechanism 4 is used to dispense adhesive onto the junction box 1 at the above-mentioned dispensing station.

[0036] The push-cover mechanism 5 is used to apply a horizontal pushing force to the box cover 12 at the above-mentioned dispensing station so that the box cover 12 changes from the first state to the second state.

[0037] The capping mechanism 6 is used to apply downward pressure to the box cover 12 at the dispensing station to change the box cover 12 from the second state to the third state.

[0038] Hot melt glue machine 7 is used to provide glue to the above-mentioned dispensing mechanism 4.

[0039] In the above description, the lid 12 has a first edge 121 and a second edge 122. The first edge 121 of the lid 12 connects to the box body 11. The opening angle of the lid 12 refers to the angle at which the second edge 122 of the lid 12 abuts against the box body 11 after the lid 12 is folded in the closing direction. For example, if the opening angle of the lid 12 is 100 degrees, then after the lid 12 is folded in the closing direction by 100 degrees, the second edge 122 of the lid 12 will abut against the box body 11. When the lid 12 is in the first state, the opening angle of the lid 12 is relatively large, such as 100°, 105°, 110°, 115°, 120°, 125°, 130°, or 135°, which does not hinder the subsequent dispensing mechanism 4 from dispensing glue, and also facilitates the push-lid mechanism 5 to apply a horizontal pushing force to the lid 12. When the lid 12 is in the second state, the opening angle of the lid 12 is small, such as a semi-closed position, such as 10°, 15°, 20°, 25°, 30°, 35°, 40° or 45°, which makes it easier for the lid pressing mechanism 6 to apply downward pressure to the lid 12.

[0040] The workbench 2 serves as the installation base for the entire dispensing equipment, supporting and installing the aforementioned loading and unloading mechanism 3, dispensing mechanism 4, cover pushing mechanism 5, cover pressing mechanism 6, and hot melt glue machine 7.

[0041] The loading and unloading mechanism 3 is used to load and unload the junction box 1. The un-glued junction box 1 is sent to the gluing station for gluing through the loading and unloading mechanism 3. The glued junction box 1 is taken away from the gluing station through the loading and unloading mechanism 3.

[0042] The dispensing mechanism 4 is used to perform the dispensing action. When the lid 12 is in the first state, the dispensing mechanism 4 applies glue to the inside of the box body 11 to seal the connection between the wiring terminals and the wires inside the box body 11. When the lid 12 is in the third state, the dispensing mechanism 4 dispenses glue at the connection between the box body 11 and the lid 12.

[0043] The push-lid mechanism 5 and the press-lid mechanism 6 work together to make the lid 12 and the box body 11 fit together.

[0044] The hot melt adhesive machine 7 is used to heat and melt solid hot melt adhesive, and then send the melted adhesive to the dispensing mechanism 4.

[0045] The following describes the working process of the dispensing equipment for the junction box, including the following steps performed in sequence:

[0046] S1. The loading and unloading mechanism 3 delivers the junction box 1 to the dispensing station;

[0047] S2, the dispensing mechanism 4 dispenses adhesive into the interior of the box 11;

[0048] S3, the push-lid mechanism 5 pushes the lid 12, causing the lid 12 to change from the first state to the second state;

[0049] S4. Pressing mechanism 6 presses down on box cover 12, causing box cover 12 to change from the second state to the third state;

[0050] S5, the glue dispensing mechanism 4 applies glue to the connection between the box body 11 and the box cover 12;

[0051] S6. The loading and unloading mechanism 3 carries the junction box 1 away from the dispensing station to complete the dispensing of the junction box.

[0052] The dispensing equipment for the junction box mentioned above achieves automated feeding and unloading of the junction box 1 through the loading and unloading mechanism 3, automated dispensing of the junction box 1 through the dispensing mechanism 4, and automated closing and fastening of the junction box 1 through the push-cover mechanism 5 and the press-cover mechanism 6. This achieves automated dispensing, reduces manual labor, and improves dispensing efficiency and accuracy.

[0053] In this embodiment, the loading and unloading mechanism 3 includes a bearing device and a first translation device 31. The bearing device is used to support and position the junction box 1, and the first translation device 31 is used to drive the bearing device to move along the horizontal X-axis.

[0054] When loading junction box 1, it is first placed on the support device, and then the first translation device 31 carries the support device and junction box 1 to the dispensing station. When unloading junction box 1, the first translation device 31 carries the support device and junction box 1 away from the dispensing station. Specifically, the first translation device 31 is an electric cylinder.

[0055] In this embodiment, the above-mentioned supporting device includes a carrier 32, a storage frame 33, and a pressure arm 34. The carrier 32 is used to position the box 11, the storage frame 33 is used to store the wires outside the junction box 1, and the pressure arm 34 is used to press the wires between the carrier 32 and the storage frame 33.

[0056] The carrier 32 has a groove that matches the shape of the junction box 1's body 11, which can position the junction box 1's body 11, thus ensuring that the body 11 remains fixed during subsequent glue application and cover installation. One end of the wire extends into the junction box 1 and connects to the terminal block inside the junction box 1, while the rest of the wire is located outside the junction box 1. Since the junction box 1 moves under the action of the first translation device 31, placing the wire outside the junction box 1 in the storage frame 33 ensures smooth movement of the junction box 1.

[0057] In this embodiment, the dispensing mechanism 4 includes a dispensing device 41 and a first lifting device 42. The dispensing device 41 is connected to the hot melt glue machine 7 and is used to apply glue to the junction box 1. The first lifting device 42 is used to drive the dispensing device 41 to move up and down.

[0058] When the dispensing mechanism 4 is dispensing glue, the first lifting device 42 drives the dispensing device 41 downwards to approach the junction box 1, where the dispensing device 41 dispenses glue. After dispensing, the first lifting device 42 drives the dispensing device 41 upwards away from the junction box 1, without obstructing the subsequent opening of the junction box 1 or its departure from the dispensing station. Specifically, the first lifting device 42 is an electric cylinder.

[0059] In this embodiment, the workbench 2 is provided with two dispensing stations arranged at intervals along the horizontal Y-axis. The dispensing mechanism 4 also includes a second translation device 43, which is used to drive the dispensing device 41 to translate along the horizontal Y-axis so that the dispensing device 41 moves back and forth between the two dispensing stations.

[0060] By setting up two dispensing stations that share the same dispensing mechanism 4, the other station can close the lid while one station is dispensing. This not only improves dispensing efficiency but also saves on equipment and reduces costs. Specifically, the second translation device 43 is an electric cylinder.

[0061] In this embodiment, the loading and unloading mechanism 3 is configured as two that are arranged at intervals along the horizontal Y-axis. The loading and unloading mechanism 3 corresponds one-to-one with the dispensing station. The loading and unloading mechanism 3 is used to deliver the junction box 1 to and take it away from the corresponding dispensing station.

[0062] Since junction box 1 is placed on loading / unloading mechanism 3 during both the dispensing and closing processes, two loading / unloading mechanisms 3 need to be set up to achieve the purpose of dispensing glue at one dispensing station and closing the cover at the other dispensing station, as mentioned above.

[0063] In this embodiment, two push-cover mechanisms 5 are arranged at intervals along the horizontal Y-axis. Each push-cover mechanism 5 corresponds to one of the dispensing stations, and each push-cover mechanism 5 applies a horizontal pushing force to the cover 12 of the corresponding dispensing station. Similarly, two press-cover mechanisms 6 are arranged at intervals along the horizontal Y-axis. Each press-cover mechanism 6 corresponds to one of the dispensing stations, and each press-cover mechanism 6 applies a downward pushing force to the cover 12 of the corresponding dispensing station.

[0064] Both the push-cap mechanism 5 and the press-cap mechanism 6 are relatively small in size, so setting one push-cap mechanism 5 and one press-cap mechanism 6 for each dispensing station will not significantly increase the cost.

[0065] In this embodiment, the push-cover mechanism 5 includes a push plate 51 and a third translation device 52. The push plate 51 is used to contact the lid 12, and the third translation device 52 is used to drive the push plate 51 to translate. The pressing mechanism 6 includes a pressing plate 61 and a second lifting device 62. The pressing plate 61 is used to contact the lid 12, and the second lifting device 62 drives the pressing plate 61 to rise and fall.

[0066] The shape and size of the push plate 51 are designed according to the shape and size of the cover of the junction box 1, and the shape and size of the pressure plate 61 are designed according to the shape and size of the cover of the junction box 1. The third translation device 52 provides power for pushing the cover, and the second lifting device 62 provides power for pressing the cover. Specifically, both the third translation device 52 and the second lifting device 62 are cylinders.

[0067] In this embodiment, the push plate 51 is horizontally arranged and has a groove 511. The groove 511 faces the cover 12. When the push plate 51 applies a pushing force to the cover 12, the cover 12 is embedded in the groove 511.

[0068] The aforementioned pressure plate 61 is vertically arranged and includes an upper pressure plate portion 611 and a lower pressure plate portion 612 connected vertically. The width of the upper pressure plate portion 611 is greater than the width of the lower pressure plate portion 612. When the pressure plate 61 applies pressure to the box cover 12, the lower pressure plate portion 612 is embedded in the aforementioned groove 511.

[0069] In the above description, the push plate 51 is U-shaped when viewed from above. By setting the groove 511, when a pushing force is applied to the lid 12, the lid 12 is embedded in the groove 511, which can push the lid 12 more accurately. The pressure plate 61 is inverted U-shaped when viewed from the side. The width of the upper pressure plate part 611 is greater than the groove width of the groove 511. When the pressure plate 61 is pressed down to a certain extent, the upper pressure plate part 611 cannot continue to move down, preventing the pressure plate 61 from pressing the lid 12 too much.

[0070] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
