Detailed Implementation

[0027] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0028] In response to the frequent problem of junction box jamming in the flipping mechanism of existing junction box installation machines, the inventors conducted research and analysis and found that the junction box installation machine includes a flipping mechanism, which includes a flipping platform. The flipping platform is 2mm thick, which is prone to cracking and unevenness. At the same time, the force on the flipping platform is uneven, causing the flipping platform to be misaligned during the flipping process. When the junction box is conveyed to the flipping mechanism, it is not pushed into place, and the junction box jams during the flipping process, resulting in frequent alarms and forced production line interruptions. Personnel are required to step in and install the junction box, reducing the operating rate of the junction box installation machine and affecting the production efficiency, production cost and yield of the production line to varying degrees.

[0029] Based on this, the following embodiments of the flipping mechanism of this application are proposed to solve the above-mentioned technical problems.

[0030] In one embodiment, a flipping mechanism is provided for use in a junction box installation machine. The flipping mechanism includes a first flipping platform 10, a second flipping platform, and a drive module. The second flipping platform is disposed opposite to the first flipping platform 10. The drive module is connected to both the first flipping platform 10 and the second flipping platform, and is used to drive the first flipping platform 10 and the second flipping platform to move closer or further apart to clamp or release the junction box, and to drive the junction box to flip when the first flipping platform 10 and the second flipping platform cooperate to clamp the junction box.

[0031] In the above embodiment, the flipping mechanism operates as follows: First, the drive module drives the first flipping platform 10 and the second flipping platform to move away from each other to open. Then, after the junction box is transported between the first flipping platform 10 and the second flipping platform, the drive module drives the first flipping platform 10 and the second flipping platform to move closer together, so that the first flipping platform 10 and the second flipping platform cooperate to clamp the junction box. Finally, the drive module drives the first flipping platform 10 and the second flipping platform to flip, and the first flipping platform 10 and the second flipping platform cooperate to correspondingly drive the junction box to flip.

[0032] The structures of the first flipping platform 10 and the second flipping platform can be the same or different. Specifically, in this embodiment, the structures of the first flipping platform 10 and the second flipping platform are the same and symmetrically arranged. In other embodiments, the structures of the first flipping platform 10 and the second flipping platform can be different, with the second flipping platform fixedly mounted on the drive module, and the first flipping platform being connected to the drive module via a transmission connection, and able to move closer to or further away from the second flipping platform under the drive of the drive module.

[0033] Optionally, both the first flipping platform 10 and the second flipping platform include a connector 300. The drive module includes a flipping mechanism, a mounting body, and a linear drive mechanism. The linear drive mechanism is mounted on the mounting body and is driveably connected to both connectors 300. The flipping mechanism is driveably connected to the mounting body. Thus, the linear drive mechanism can drive the first flipping platform 10 and the second flipping platform to move closer or further apart to clamp or release the junction box, and the flipping mechanism can drive the first flipping platform 10 and the second flipping platform to flip through the mounting body and the linear drive mechanism, thereby enabling the first flipping platform 10 and the second flipping platform to cooperate in driving the junction box to flip, improving the practicality of the flipping mechanism.

[0034] The flipping mechanism can be set to any of the existing rotary drive structures.

[0035] Specifically, in this embodiment, the flipping mechanism drives the mounting body to rotate clockwise or counterclockwise, enabling continuous flipping actions. This eliminates the need for the mounting body to reset, improving the flipping cycle time and stability of the junction box mounting machine.

[0036] In this specific embodiment, the flipping mechanism is fixed to the mounting body by multiple bolts and at least two locating pins. This reduces the risk of wobbling during the flipping process of the first and second flipping platforms, ensures more accurate flipping into position, and improves the reliability of the flipping mechanism.

[0037] The mounting body can be configured as a mounting plate, mounting bracket, or other mounting structure. The linear drive mechanism can be any linear drive structure in the prior art. Specifically, in this embodiment, the flipping mechanism and the linear drive mechanism are located on opposite sides of the mounting body.

[0038] Optionally, both connectors 300 are slidably engaged with the mounting body. Specifically, in this embodiment, the flipping mechanism includes two slide rails and four sliders. The two slide rails are mounted on the side of the mounting body closest to the linear drive mechanism, and are located on opposite sides of the linear drive mechanism. The extension direction of the slide rails is the same as the driving direction of the linear drive structure. Each slide rail is slidably connected to two sliders. The two sliders on each slide rail are respectively fixedly connected to the two connectors 300 one-to-one. Thus, the cooperation between the slide rails and sliders can guide and limit the connectors 300, ensuring that the first flipping platform 10 and the second flipping platform maintain consistent horizontality and uniform force as they move closer or further apart, thereby improving the junction box flipping success rate.

[0039] like Figure 1 As shown, in one embodiment, the first flipping platform 10 and / or the second flipping platform includes a platform body 100, a reinforcing rib assembly 200, and a connector 300 for transmission connection with the drive module. The reinforcing rib assembly 200 is installed on the back side 111 of the platform body 100. The connector 300 is installed on one side of the platform body 100 and is fixedly connected to the reinforcing rib assembly 200. Thus, the reinforcing rib assembly 200 is connected to both the platform body 100 and the connector 300 to increase the overall strength of the first flipping platform 10 and / or the second flipping platform. This ensures that the platform body 100 is subjected to uniform force, and that the platform body 100 does not shake or misalign during the clamping and flipping process of the junction box. This effectively solves the problem of the junction box getting stuck during the flipping process, eliminates the need for personnel to reposition and install the junction box, improves the production efficiency and yield of the production line, and reduces the production cost of the production line.

[0040] The connector 300 can be configured as a connecting block, a connecting seat, or other connecting structure. Both the platform body 100 and the connector 300 can be made of high-strength, wear-resistant sheet metal to reduce the cost of replacing worn parts later.

[0041] It should be noted that the surface of the platform body 100 used for contacting and clamping with the junction box is designated as the front side. The back side 111 refers to the side of the platform body 100 away from the front side.

[0042] The thickness of the platform body 100 can be flexibly adjusted according to actual usage needs. For example, the thickness of the platform body 100 can be 5mm to 8mm. Specifically, in this embodiment, the thickness of the platform body 100 is 6mm.

[0043] The reinforcing rib assembly 200 can be installed on the back surface 111 of the platform body 100 by screwing, snapping, plugging, or other fixed connection methods. The reinforcing rib assembly 200 can be fixedly connected to the connector 300 by screwing, snapping, plugging, or other fixed connection methods. Specifically, in this embodiment, the reinforcing rib assembly 200 is located in the middle of the back surface 111 of the platform body 100.

[0044] like Figure 1 As shown, the reinforcing rib assembly 200 further includes at least one first reinforcing rib 210. Each first reinforcing rib 210 is spaced apart on the back surface 111 of the platform body 100. One end of each first reinforcing rib 210 is fixedly connected to the connector 300. Thus, the spaced-apart first reinforcing ribs 210 make the strength distribution on the platform body 100 more uniform, improving the reliability of the tilting mechanism.

[0045] The number of the first reinforcing ribs 210 can be flexibly adjusted according to actual usage needs.

[0046] like Figure 1 As shown, optionally, there are two first reinforcing ribs 210. The reinforcing rib assembly 200 also includes at least one second reinforcing rib 220. Each second reinforcing rib 220 is spaced apart between two first reinforcing ribs 210. Both ends of each second reinforcing rib 220 are fixedly connected to the corresponding two first reinforcing ribs 210. In this way, each second reinforcing rib 220 connects the two first reinforcing ribs 210 to further improve the strength of the platform body 100, ensuring that the two platform bodies 100 will not shake or misalign during the clamping of the junction box, and improving the reliability of the flipping mechanism.

[0047] The number of the second reinforcing ribs 220 can be flexibly adjusted according to actual usage needs.

[0048] like Figure 1 As shown, optionally, the reinforcing rib assembly 200 further includes at least one third reinforcing rib 230. Each third reinforcing rib 230 is spaced apart between two first reinforcing ribs 210. One end of each third reinforcing rib 230 is fixedly connected to the connector 300. The other end of each third reinforcing rib 230 is fixedly connected to the second reinforcing rib 220 closest to the connector 300. Thus, each third reinforcing rib 230 connects the connector 300 to the second reinforcing rib 220, further improving the strength of the platform body 100, ensuring that the two platform bodies 100 do not shake or misalign during the clamping of the junction box, and improving the reliability of the flipping mechanism.

[0049] The number of second reinforcing ribs 220 can be flexibly adjusted according to actual usage needs. Any two of the first reinforcing ribs 210, second reinforcing ribs 220, and third reinforcing ribs 230 can be fixedly connected by screwing, snap-fitting, plugging, or other assembly methods. Specifically, in this embodiment, the extending direction of the first reinforcing rib 210 is perpendicular to the extending direction of the second reinforcing rib 220. The extending direction of the first reinforcing rib 210 is parallel to the extending direction of the third reinforcing rib 230.

[0050] like Figure 1 As shown, in one embodiment, each of the first reinforcing ribs 210 has a connecting portion 211 at one end near the connector 300. Each connecting portion 211 is fixedly connected to the connector 300. In this way, the connecting portion 211 can increase the fixed area between the first reinforcing rib 210 and the connector 300, thereby increasing the connection strength between the connector 300 and the reinforcing rib assembly 200 and improving the reliability of the flipping mechanism.

[0051] Specifically, in this embodiment, the connecting portion 211 is integrally formed with the first reinforcing rib 210. The connecting portion 211 is located on the side of the first reinforcing rib 210 away from the platform body 100. The extending direction of the connecting portion 211 is perpendicular to the extending direction of the first reinforcing rib 210. The side of the connecting portion 211 near the connector 300 and the end face of the first reinforcing rib 210 near the connector 300 are located in the same plane.

[0052] like Figure 1 and Figure 2 As shown, in one embodiment, each of the first reinforcing ribs 210 has a first connecting hole 212 on its end face near the connector 300. The connector 300 has at least one second connecting hole 311. Each second connecting hole 311 communicates with each first connecting hole 212. The first flipping platform 10 and / or the second flipping platform also includes at least one locking member. Each locking member passes through each second connecting hole 311 and locks into each first connecting hole 212. In this way, the connector 300 and the first reinforcing rib 210 are locked and fixed by the locking members, improving the convenience of disassembly and assembly of the flipping mechanism and reducing the labor and time costs during later maintenance and pattern switching.

[0053] The locking component can be a locking bolt, a locking pin, or other locking structure.

[0054] Specifically, in this embodiment, the connector 300 is also provided with a third connecting hole 312 for fixing the slider and a fourth connecting hole 313 for fixing the linear drive mechanism.

[0055] like Figure 1 and Figure 2As shown, optionally, the second connecting hole 311 is a stepped hole. The first connecting hole 212 is a threaded hole. The locking element includes a bolt head and a bolt body connected to each other. The bolt head is located in the stepped hole and abuts against the stepped surface of the stepped hole. The bolt body extends into the threaded hole and is threadedly engaged with the threaded hole. In this way, the bolt head is hidden in the second connecting hole 311, avoiding interference between the bolt head and surrounding components or wires, and improving the reliability of the flipping mechanism.

[0056] Specifically, in the embodiment of the main body, the stepped hole has a first hole segment and a second hole segment that are connected to each other. The inner diameter of the first hole segment is larger than the inner diameter of the second hole segment. The inner diameter of the second hole segment is larger than the inner diameter of the threaded hole. The second hole segment is connected to the threaded hole.

[0057] Specifically, in this embodiment, the connection structure between the connecting part 211 and the connecting member 300, the connection structure between the connecting member 300 and the platform body 100, the connection structure between the first reinforcing rib 210 and the platform body 100, the connection structure between the second reinforcing rib 220 and the platform body 100, the connection structure between the third reinforcing rib 230 and the platform body 100, and the connection structure between the third reinforcing rib 230 and the connecting member 300 can all be the same as or similar to the connection structure between the connecting member 300 and the first reinforcing rib 210, and will not be described in detail here.

[0058] Optionally, the first flipping platform 10 and / or the second flipping platform also include a fixing adhesive. The fixing adhesive fills the gap between the locking member and the inner wall of the first connecting hole 212, and / or the gap between the locking member and the inner wall of the second connecting hole 311. In this way, the fixing adhesive can increase the connection strength between the locking member and the platform body 100 and / or the connecting member 300, ensuring that the locking member will not loosen even after long-term use, reducing the shaking and misalignment of the platform body 100, improving the reliability of the flipping mechanism, and extending the service life of the junction box installation machine.

[0059] like Figure 1 As shown, in one embodiment, the first flipping platform 10 and / or the second flipping platform further include a first stop bar 400 and a second stop bar 500. The first stop bar 400 is installed on the side of the platform body 100 near the connector 300. The second stop bar 500 is installed on the side of the platform body 100 away from the connector 300. Both the first stop bar 400 and the second stop bar 500 are used to block the junction box and the wires electrically connected to the junction box. Thus, the first stop bar 400 can prevent the wires from moving out of the platform body 100, thereby reducing the risk of interference between the wires and the linear drive mechanism or other surrounding components, and the second stop bar 500 can prevent the junction box from being thrown out of the platform body 100, thereby improving the reliability of the junction box installation machine.

[0060] The first stop bar 400 and the second stop bar 500 can be installed on the platform body 100 by screwing, snapping, plugging or other fixed connection methods.

[0061] Specifically, in this embodiment, both the first flipping platform 10 and the second flipping platform include a platform body 100, a reinforcing rib assembly 200, a connector 300, a locking component, a fixing adhesive, a first stop bar 400, and a second stop bar 500.
