Description

Technical Field

[0001] This invention relates to the field of electricity meter manufacturing technology, and in particular to an assembly equipment for electricity meter terminal boxes. Background Technology

[0002] Existing electricity meters typically consist of a casing, a PCB board housed within the casing, and a terminal box connected to the PCB board. In current technology, the terminal box is mostly assembled manually by inserting pins from the terminal box into corresponding positions on the PCB board. This method is inefficient, detrimental to cost savings, and the manual installation results in inconsistent installation quality, affecting the meter's factory pass rate. Summary of the Invention

[0003] In view of the above problems, the purpose of this invention is to provide an energy meter terminal box assembly equipment with high production efficiency and which is conducive to improving the installation quality of the terminal box.

[0004] To achieve the above objectives, the technical solution of the present invention is: an assembly device for a power meter terminal box, characterized in that:

[0005] The device includes a frame, a rotatable turntable assembly mounted on the frame, a loading assembly mounted outside the turntable assembly to feed PCB boards to be assembled onto the turntable assembly, a unloading assembly mounted outside the turntable assembly to remove PCB boards assembled on the turntable assembly, an end-button box conveying assembly located between the loading assembly and the unloading assembly to feed end-button boxes to the turntable assembly, and a transfer assembly assembly located between the end-button box conveying assembly and the unloading assembly to move end-button boxes on the end-button box conveying assembly to the top of the turntable assembly for assembly with the PCB boards to be assembled.

[0006] After the feeding component transports the PCB board to be assembled to the turntable component, the turntable component rotates by a first angle value so that the end button box transferred by the transfer assembly component can be inserted and assembled with the PCB board to be assembled on the turntable component. After the end button box and the PCB board are assembled, the turntable component rotates by a second angle value so that the unloading component can remove the assembled PCB board.

[0007] Furthermore, the turntable assembly includes a turntable body and multiple sets of fixtures disposed on the turntable body. The multiple sets of fixtures are equally spaced on the same circumference surrounding the rotation axis of the turntable body. The PCB board to be assembled is transferred to the fixture by the feeding assembly.

[0008] Furthermore, the feeding assembly includes a first conveyor belt and a first robotic arm that transfers the PCB board to be assembled on the first conveyor belt to the fixture.

[0009] Furthermore, the unloading assembly includes a second conveyor belt and a second robotic arm that transfers the assembled PCB board from the fixture to the second conveyor belt.

[0010] Furthermore, the end-button box conveying assembly includes a third conveyor belt and a calibration component disposed at the end of the third conveyor belt near the turntable body for calibrating the connecting pins on the end-button box.

[0011] Furthermore, each set of fixtures consists of two units, and the corresponding number of transfer assembly components is two.

[0012] Furthermore, the transfer assembly assembly includes a third robotic arm.

[0013] Furthermore, the first angle value is 90°, and the second angle value is 180°.

[0014] Furthermore, the fixture has four sets and is evenly distributed on the circumference of the turntable body.

[0015] Furthermore, the turntable body is provided with a push cylinder that can push the PCB board to be assembled on the jig in the assembly position radially outward to correct the position of the PCB board to be assembled.

[0016] Compared with the prior art, the advantages of the present invention are as follows: the setting of the feeding and unloading components can realize the automatic loading and unloading of PCB boards; the setting of the end button box conveying component can realize the automatic feeding of end button boxes; and the setting of the transfer assembly component can realize the automatic assembly between end button boxes and PCB boards. The entire assembly process does not require manual operation, has a high degree of automation, and is fast, which is conducive to improving production efficiency. At the same time, the setting of the correction component and the push cylinder is conducive to improving the assembly quality and increasing the factory qualification rate of the electricity meter.

[0022] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0023] like Figures 1 to 5 This is a schematic diagram of a preferred embodiment of the present invention. As shown in the figure, the electricity meter terminal box installation equipment includes a frame 1, a rotatable turntable assembly mounted on the frame 1, a feeding assembly disposed outside the turntable assembly to convey a PCB board 900 to be assembled onto the turntable assembly, a unloading assembly disposed outside the turntable assembly to remove the assembled PCB board 900 from the turntable assembly, a terminal box conveying assembly located between the feeding assembly and the unloading assembly to convey the terminal box 901 to be assembled onto the turntable assembly, and a terminal box conveying assembly disposed between the terminal box conveying assembly and the unloading assembly. The assembly process involves a transfer assembly assembly that moves end-button boxes 901 from the end-button box conveyor assembly to the top of the turntable assembly for assembly with the PCB board 900 to be assembled. After the loading assembly conveys the PCB board 900 to the turntable assembly, the turntable assembly rotates by a first angle to allow the end-button box 901 from the transfer assembly assembly to engage with the PCB board 900 on the turntable assembly. Once the end-button box 901 and PCB board 900 are assembled, the turntable assembly rotates by a second angle to allow the unloading assembly to remove the assembled PCB board 900. The entire process requires no manual operation, is highly automated, has a fast assembly speed, and helps save costs.

[0024] Specifically, the turntable assembly includes a turntable body 21 and multiple sets of fixtures 22 disposed on the turntable body 21. The multiple sets of fixtures 22 are equally spaced on the same circumference surrounding the rotation axis of the turntable body. The PCB board 900 to be assembled is transferred to the fixtures 22 by the feeding assembly. Of course, the turntable assembly also includes a drive device for driving the rotation of the turntable body 21, such as a drive motor, etc., which will not be described in detail here.

[0025] In this embodiment, the loading component includes a first conveyor belt 31 and a first robotic arm 32 that transfers the PCB board 900 to be assembled on the first conveyor belt 31 to the fixture 22. The first conveyor belt 31 transports the PCB board 900 to be assembled toward the turntable body 21, and the first robotic arm 32 transfers the PCB board 900 to be assembled on the first conveyor belt 31 to the fixture 22 on the turntable body 21, thereby realizing automatic loading of the PCB board 900. In order to realize automatic unloading of the assembled PCB board 900, the unloading component includes a second conveyor belt 41 and a second robotic arm 42 that transfers the assembled PCB board 900 on the fixture 22 to the second conveyor belt 41. The assembled PCB board 900 is transported by the second conveyor belt 41 to the next process.

[0026] In this embodiment, the end-cap box conveying assembly includes a third conveyor belt 51 and a correction component 52 disposed at the end of the third conveyor belt 51 near the turntable body 21 for correcting the connecting pins on the end-cap box 901. The main function of the correction component 52 is that the connecting pins may become skewed during the production and assembly process of the end-cap box 901. The correction component 52 mainly corrects the skewed connecting pins to prevent them from becoming skewed. The correction component 52 mainly includes a fixing clamp for fixing the end-cap box 901 and a sleeve hole for pushing the side of the connecting pin. Since this type of correction component 52 is common in the production of power electronic equipment, its detailed structure will not be described in detail in this application.

[0027] To improve assembly efficiency, each set of jigs 22 consists of two jigs, and the number of assembly components transferred is also two. Of course, the number of jigs 22 can be increased to further improve assembly efficiency.

[0028] In this embodiment, the transfer assembly component includes a third robotic arm 6. As a preferred embodiment, the third robotic arm 6 is a four-arm robotic arm, which can improve the flexibility of assembly.

[0029] In this embodiment, the first angle value is 90° and the second angle value is 180°. That is, the loading component transfers the PCB board 900 to be assembled onto the turntable body 21, then the turntable body 21 rotates 90°, and the assembly component assembles the end-button box 901 with the PCB board 900. After assembly, the turntable body 21 continues to rotate 180°, and the unloading component removes the assembled PCB board 900. It should be noted that, for ease of operation, the turntable body 21 stops rotating during loading, assembly, and unloading. After the corresponding operation is completed, the turntable body 21 resumes rotation. Of course, it is conceivable that the first and second angle values ​​can be other values. Here, another preferred method is listed: when both the first and second angle values ​​are 90°, the first conveyor belt 31 and the second conveyor belt 41 can use the same conveyor belt, thereby saving costs.

[0030] In this embodiment, the central angle between two adjacent sets of fixtures 22 on the turntable body 21 is 90°, that is, there are four sets of fixtures 22 and they are evenly distributed on the circumference of the turntable body 21.

[0031] To facilitate precise positioning of the PCB board 900 to be assembled and to ensure alignment of the connector pins when inserting the end-cap 901, a push cylinder 71 is provided above the turntable body 21 to radially push the PCB board 900 to be assembled on the fixture 22 at the assembly position outward. To protect the end-cap 901, the push cylinder 71 also has a push block 72 and other components at its pushing end. The push cylinder 71 can be fixed by a frame above the turntable body 21, or it can be installed by opening a through hole in the middle of the turntable body 21. The installation method of the push cylinder 71 is not the focus of this application and will not be described in detail.

[0032] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
