[0030] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present application belongs.

[0031] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0032] In order to solve the problems of low automation, high labor cost and low production efficiency in the existing manual alignment method of air conditioner indoor units, the present invention provides a production position correction device for air conditioner indoor units.

[0033] like Figure 1 and Figure 2 As shown, the air conditioner indoor unit production position correction device includes a conveying platform 1, a linear guide rail, two sliders (4, 12), two limit fixtures (5, 8) and a driving unit. The linear guide rail is set on the conveying platform 1 and is located above the conveying path of the air conditioner indoor unit 11 to Figure 2Taking the orientation shown as an example, the projection of the linear guide rail on the conveying plane of the conveying platform 1 corresponds to the diagonal line of the rectangle formed by the horizontal projection of the air conditioner indoor unit 11 in the standard position on the conveying plane, and the two sliders (4, 12) are respectively connected to the linear guide rail for sliding. Specifically, the slider 4 is slidably connected to the linear guide rail at the upper left corner of the air conditioner indoor unit 11, and the slider 12 is slidably connected to the linear guide rail at the lower right corner of the air conditioner indoor unit 11. The two limiting fixtures (5, 8) are respectively connected to the two sliders (4, 12). Specifically, the top of the limiting fixture 5 is connected to the bottom of the slider 4, and is used to abut against the left end face and back face of the vertical edge forming the upper left corner of the air conditioner indoor unit 11. The top of the limiting fixture 8 is connected to the bottom of the slider 12, and is used to abut against the right end face and front face of the vertical edge forming the lower right corner of the air conditioner indoor unit 11. The driving part is also arranged on the conveying platform 1, and the output end of the driving part is connected to the two sliders ( 4, 12) driving connection, used for driving the two sliders (4, 12) to slide along the linear guide rail, thereby driving the two limiting fixtures (5, 8) to approach or move away from each other, so that when the limiting fixture 5 and the limiting fixture 8 approach each other, the limiting fixture 5 abuts against the left end face and back face of the air-conditioning indoor unit 11, limiting the upper left corner of the air-conditioning indoor unit 11, and the limiting fixture 8 abuts against the right end face and front face of the air-conditioning indoor unit 11, limiting the lower right corner of the air-conditioning indoor unit 11, thereby correcting the offset and tilted air-conditioning indoor unit 11 to the standard position. After the correction is completed, the limiting fixture 5 and the limiting fixture 8 move away from each other, the corrected air-conditioning indoor unit 11 flows out, and the new air-conditioning indoor unit 11 flows in.

[0034] In the present application, two limiting fixtures (5, 8) are used to move toward each other in the diagonal direction of the air-conditioning indoor unit 11, so as to realize all-round correction of the front, rear, left and right of the air-conditioning indoor unit 11 on the conveying platform 1 at one time. Compared with the correction device of the prior art, which needs to set up the front and rear correction mechanisms and the left and right correction mechanisms respectively, the correction device of the present application has a simple and compact structure and a higher degree of automation, and can realize rapid correction of the air-conditioning indoor unit 11, which not only improves efficiency but also reduces maintenance costs.

[0035] In this embodiment, the two limiting fixtures (5, 8) have the same structure, both of which are vertically arranged L-shaped plate structures, and the long sides of the L-shaped plate structures are parallel to the length direction of the air-conditioning indoor unit 11. In this way, by adjusting the stroke of the two limiting fixtures (5, 8), the correction angle of the air-conditioning indoor unit 11 can be greatly increased, that is, the correction area of the air-conditioning indoor unit 1 can be greatly increased.

[0036] It should be noted that the structure of the limiting fixtures (5, 8) can be flexibly designed according to the appearance of the air conditioner indoor unit 11, and corresponding buffer designs can be added as needed, which is not limited in this embodiment.

[0037] In this embodiment, the air-conditioning indoor unit 11 is placed on the workbench 10, and the workbench 10 is located on the conveying mechanism of the conveying platform 1. The air-conditioning indoor unit 11 flows into the correction device in sequence through the conveying platform 1. In this way, the air-conditioning indoor unit 1 can be positioned at the correction station by positioning the workbench 10. As for the specific conveying method of the conveying platform 1, this embodiment does not limit it.

[0038] In this embodiment, the driving part includes a rotary driving component 9, a turntable 13 and two connecting rods (3, 6). The rotary driving component 9 is arranged on the conveying platform 1 and is located above the linear guide rail. The turntable 13 is connected to the power output end of the rotary driving component 9. The turntable 13 is arranged horizontally and is located between the two sliders (4, 12). The two connecting rods (3, 6) are respectively arranged on both sides of the turntable 13. Figure 2 As shown, the connecting rod 3 is located on the left side of the turntable 13, with one end of the connecting rod 3 being rotatably connected to the turntable 13 and the other end being rotatably connected to the slider 4. The connecting rod 6 is located on the right side of the turntable 13, with one end of the connecting rod 6 being rotatably connected to the turntable 13 and the other end being rotatably connected to the slider 12. In this way, when the rotary drive component 9 is started, the turntable 13 is driven to rotate, and the rotation of the chassis 13 drives the two connecting rods (3, 6) connected thereto to swing. Since the linear guide rail is fixed, the sliders (4, 12) will move toward each other along the linear guide rail under the push of the connecting rods (3, 6), thereby driving the two limit fixtures (5, 8) to move closer to or away from each other.

[0039] Optionally, the rotary drive component 9 is a vertically arranged motor, and the rotation center of the turntable 13 is connected to the output shaft of the motor.

[0040] Optionally, the turntable 13 is waist-shaped as a whole, and the two connecting rods (3, 6) are rotatably connected to the arc-shaped parts of the turntable 13 respectively. The waist-shaped disc structure can reduce the weight of the turntable 13 and more intuitively show the swing direction of the connecting rods (3, 6).

[0041] In this embodiment, to avoid the need for rotary drive component 9, the linear guide is divided into two sections: linear guide 2 and linear guide 7. This arrangement also reduces guide rail costs. Specifically, linear guide 2 is located at the upper left corner of the air conditioner 11 and is slidably connected to slider 4. Linear guide 7 is located at the lower right corner of the air conditioner 11 and is slidably connected to slider 12. Linear guides 2 and 7 are arranged in a straight line, and their projections on the conveying plane of the conveyor platform 1 correspond to the diagonals of the rectangle formed by the horizontal projection of the air conditioner 11 on the conveying plane.

[0042] In an embodiment not shown in the figure of the present application, the driving part can be an electric cylinder, and the two sliders (4, 12) are provided with threaded holes connected to the screw of the electric cylinder, and the thread direction of the threaded hole of the slider 4 is opposite to the thread direction of the threaded hole of the slider 12. In this way, by rotating the screw, the sliders (4, 12) can be driven to move toward each other along the linear guide rail.

[0043] In an embodiment not shown in the figure of the present application, the driving part can adopt two driving cylinders, the output end of one driving cylinder is connected to the slider 4, and the output end of the other driving cylinder is connected to the slider 12. In this way, as long as the actions of the two driving cylinders are controlled synchronously, the sliders (4, 12) can be driven to move toward each other along the linear guide rail.

[0044] use Figure 1 and Figure 2 The correction device in the specific embodiment shown in the figure performs the position correction operation of the air conditioner indoor unit, including the following process:

[0045] The air conditioner indoor unit 11 is placed on the workbench 10 and flows into the correction device through the conveyor 1. When the workbench 10 reaches the designated position, the rotary drive component 9 drives the turntable 13 to rotate counterclockwise. At this time, the slider 4, the limit fixture 5, the limit fixture 8, and the slider 12 are driven by the connecting rods 3 and 6 with the rotary drive component 9 as the rotation center. They move toward the rotation center along the linear direction of the linear guide rails 2 and 7. During this movement process, the position of the air conditioner indoor unit 11 is corrected and fixed, thereby achieving the requirements of marking and spraying.

[0046] After the marking and spraying work is completed, the rotary drive component 9 reverses and drives the turntable 13 to rotate clockwise. The motor 9 will also be used as the rotation center. The slider 4, the limit tooling 5, the limit tooling 8, and the slider 12 will be moved by the connecting rod 3 and the connecting rod 6, and move in the opposite direction of the rotation center along the linear direction of the linear guide rail 2 and the linear guide rail 7 until the rectification and correction work is completed after reaching the specified position.
