Description

[Technical Field]

[0001] This utility model belongs to the field of controller structure technology, and in particular relates to a controller. [Background Technology]

[0002] In photovoltaic (PV) module production equipment, automated conveyor lines are required to automatically transport PV modules. Each independently controlled conveyor line is equipped with multiple motors and controllers to control their operation. For the entire PV module production line, the installation of these controllers adds a significant workload for assembly personnel. Currently, there are generally two installation methods for controllers: direct mounting on the equipment frame profile or mounting on a dedicated bracket. For mounting on a dedicated bracket, operators must first install the bracket on the equipment frame profile and then place and tighten the controller. For direct mounting on the equipment frame profile, the installer typically needs one hand to support or hold the controller while the other hand tightens the screws, making the operation very inconvenient and sometimes requiring two people to complete the installation.

[0003] Therefore, it is necessary to provide a new controller to solve the above-mentioned technical problems. [Utility Model Content]

[0004] The main purpose of this utility model is to provide a controller that can be directly installed on the equipment frame profile by only one person, which greatly improves the convenience and efficiency of installation.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a controller, which includes a main housing, a front cover covering the front side of the main housing, a control circuit board disposed in the main housing, and a mounting plate fixed on the main housing; the mounting plate includes a horizontal mounting piece fixedly mounted to the upper surface of the equipment frame profile; the mounting piece has a snap-fit ​​piece at a set position from the rear surface of the main housing that extends downward into a corresponding groove on the upper surface of the profile.

[0006] Furthermore, the horizontal mounting plate is provided with a pair of waist-shaped mounting holes, and the mounting plate is fixedly connected to the profile by screws passing through the waist-shaped mounting holes and engaging with nuts inserted into the grooves.

[0007] Furthermore, the mounting plate includes a vertical plate arranged in an L-shape with the horizontal mounting piece; the vertical plate is fixedly connected to the rear side of the main housing.

[0008] Furthermore, the mounting plate is fixed to the top of the main housing; a portion of the horizontal mounting piece is fixedly connected to the top of the main housing, and another portion is fixedly connected to the upper surface of the profile; the snap-fit ​​piece is disposed in the portion of the horizontal mounting piece connected to the profile.

[0009] Furthermore, a number of heat sinks are provided on the rear surface of the main housing.

[0010] Furthermore, the heat sink is arranged vertically and a heat dissipation groove is formed between two adjacent heat sinks, and the rear side of the heat dissipation groove is an open structure and is in close contact with the front surface of the profile.

[0011] Furthermore, the heat sink is arranged horizontally, and a heat dissipation groove is formed between two adjacent heat sinks. The rear side of the heat dissipation groove is an open structure and is in close contact with the front surface of the profile.

[0012] Furthermore, some electronic components on the control circuit board are mounted close to the inner wall of the rear side panel of the main housing.

[0013] Compared with the prior art, the beneficial effect of the controller of this utility model is that: by setting a mounting plate with a horizontal mounting piece on the top of the main housing, and setting a snap-fit ​​piece on the horizontal mounting piece, the controller can be hung on the profile by snapping the snap-fit ​​piece into the groove on the top of the profile, without the need for additional hands or another installer to assist in fixing the controller. This frees up the installer's hands to focus on the locking operation of the mounting plate, thereby improving the convenience and efficiency of controller installation. [Attached Image Description]

Detailed Implementation Methods

[0021] Example 1:

[0022] Please refer to Figures 1-3 This embodiment is a controller 100, which includes a main housing 1, a front cover 2 covering the front side of the main housing 1, a control circuit board (not shown in the figure) disposed in the main housing 1, and a mounting plate 3 fixed to the rear side of the main housing 1.

[0023] To facilitate the installation of the controller onto the profile 200 of the equipment frame, the structure of the mounting plate 3 has been optimized in this embodiment. Specifically, the mounting plate 3 includes a vertical plate 31 and a horizontal mounting piece 32. The vertical plate 31 and the horizontal mounting piece 32 are integrated into an L-shaped sheet metal part. The vertical plate 31 is fixedly connected to the rear side of the main housing 1. The connection method can be screw connection, riveting, snap connection, or welding. In this embodiment, screw connection is used. The vertical plate 31 is provided with several mounting holes 311 for screws to pass through. During installation, the horizontal mounting piece 32 rests on the upper surface of the equipment frame profile 200. The mounting plate 3 is fixedly connected to the equipment frame profile by screws and nuts inserted into the grooves of the profile. The horizontal mounting piece 32 is provided with a pair of waist-shaped mounting holes 321. The length extension direction of the waist-shaped mounting holes 321 is consistent with the extension direction of the profile 200, thereby facilitating the position adjustment of the mounting plate 3. When installing the controller, the rear side of the main housing 1, along with the vertical plate 31, is tightly attached to the front surface of the profile 200, and the horizontal mounting plate 32 rests on the upper surface of the profile 200. At this time, the center of gravity of the controller is on the front side of the vertical plate 31. If the horizontal mounting plate 32 is not restricted by external downward pressure, the controller will fall forward. To prevent the controller from falling and to free up the installer's hands, which are used entirely for the controller fixing and locking operation, a downwardly bent buckle 322 is provided on the horizontal mounting plate 32 at a set distance from the vertical plate 31. The downward extension length of the buckle 322 is less than or equal to the groove depth on the upper surface of the profile 200. The distance between the clip 322 and the vertical plate 31 is set according to the position of the groove on the upper surface of the profile. At the set distance, after the clip 322 is inserted into the groove 201 on the upper surface of the profile 200, the groove 200 holds the clip 322 in place, preventing the horizontal mounting plate 32 from flipping up and the controller from moving forward, thus effectively preventing the controller from flipping forward.

[0024] Without the design of the latching piece 322, the installer would need to press down the horizontal mounting piece 32 with their hand to prevent the controller from tipping over. This would require only one hand to complete the locking operation of the horizontal mounting piece 32, which is very inconvenient. Alternatively, another installer would be needed to complete the locking operation of the horizontal mounting piece 32, which would be labor-intensive.

[0025] In this embodiment, the controller is an integrated controller, with an internal control circuit board that integrates a motor controller and a drive controller. Since the control circuit board contains numerous electronic components, heat dissipation is a crucial consideration. To improve heat dissipation, this embodiment provides several heat sinks 11 on the rear surface of the main housing 1. The heat sinks 11 are vertically arranged, and a vertically penetrating heat dissipation groove 12 is formed between adjacent heat sinks 11. The rear side of the heat dissipation groove 12 is open and closely adheres to the front surface of the equipment frame profile. The heat sinks 11 conduct heat from inside the main housing 1 to the equipment frame profile, fully utilizing the equipment frame profile for heat dissipation, eliminating the need for additional cooling fans while ensuring effective heat dissipation.

[0026] In other embodiments, the heat sink 11 may also be arranged horizontally, in which case the heat dissipation groove 12 formed between two adjacent heat sinks 11 is a through structure, and the rear side of the heat dissipation groove 12 is still completely open, aligned and closely attached to the front surface of the equipment frame profile.

[0027] Some electronic components on the control circuit board are mounted close to the inner wall of the rear side panel of the main housing 1 for rapid heat dissipation.

[0028] When the controller is installed on the profile 200, the installer can directly use the clips 322 on the mounting plate 3 to snap into the groove 201 on the top of the profile 200 and hang the entire controller on the profile 200. After adjusting the position, the installer can use both hands to perform the locking operation of the controller, which improves the convenience and efficiency of the controller installation.

[0029] Example 2:

[0030] Please refer to Figure 4 This embodiment is a controller, which has a structure that is basically the same as that in Embodiment 1, except that the structure of the mounting plate 3 is different. Specifically, in this embodiment, the mounting plate 3 is fixed to the top of the main housing 1 and has only one horizontal mounting piece 32. A portion of the horizontal mounting piece 32 is used for fixed connection with the top of the main housing 1, and this portion is provided with at least one pair of mounting holes 311; another portion is used for fixed connection with the upper surface of the profile 200, and this portion is provided with a waist-shaped mounting hole 321 and a snap-fit ​​piece 322.

[0031] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
