[0130] The working principle of an automatic production line for injection molding of an air conditioner indoor unit housing in this application is as follows:

[0131] When it is necessary to prepare the indoor unit casing, the raw material input mechanism 3 extracts the plastic masterbatch into the injection molding mechanism 1; the first extraction component 34 works to extract the plastic masterbatch into the transfer bin 33, and when the plastic masterbatch in the transfer bin 33 reaches a certain amount, the second extraction component 35 works to extract the plastic masterbatch from the transfer bin 33 into the melting component 13 for melting processing.

[0132] The raw material conveying mechanism 2 conveys the plastic masterbatch to the melting component 13, the melting component 13 melts the plastic masterbatch, the mold component 12 is closed, the injection component 14 works, the plastic in the melting component 13 is injected into the mold, cooled and formed, the mold component 12 is demolded, and the material taking mechanism 4 takes out the finished product.

[0133] The three-axis driving component 43 drives the negative pressure component 42 to move to the material taking position, and the negative pressure component 42 works to remove the indoor unit casing from the molding position of the injection molding mechanism 1. The three-axis driving component 43 drives the negative pressure component 42 to move above the conveying mechanism 2. The three-axis driving component 43 then drives the indoor unit casing to descend a certain distance. The swing driving component 6 drives the negative pressure component 42 to swing, so that the indoor unit casing swings to the placement angle. The three-axis driving component 43 drives the negative pressure component 42 to descend to the material discharging position, and the negative pressure component 42 puts down the indoor unit casing; the three-axis driving component 43 drives the negative pressure component 42 to move upward, and the swing driving component 6 then drives the negative pressure component 42 to swing and reset.

[0134] When the negative pressure component 42 swings, the swing driving member 68 drives the pushing member 62 to slide, the pushing member 62 drives the first swinging member 64 to swing, the first swinging member 64 drives the second swinging member 65 to swing, the second swinging member 65 drives the rotating member 63 to rotate relative to the support plate 61, the rotating member 63 drives the third swinging member 66 to swing, and the third swinging member 66 drives the negative pressure component 42 to swing, thereby realizing smooth and uniform swinging of the negative pressure component 42.

[0135] Under the action of the first conveying assembly 22 and the second conveying assembly 23 , the inner cover and the outer cover of the indoor unit casing flow to the aggregate assembly 5 respectively; and the inner cover and the outer cover flow into the aggregate assembly 5 only after passing through the dust removal assembly 24 on the first conveying assembly 22 and the second conveying assembly 23 .

[0136] The material collecting driving member 52 on the first conveying assembly 22 and the second conveying assembly 23 respectively drives the material collecting member 51 to move, and the material collecting member 51 drives the material collecting frame 53 to move, so that the material collecting frame 53 is shifted to the receiving position, and the inner cover and the outer cover enter the receiving position of the material collecting frame 53 under the guidance of the guide members 54 on the first conveying assembly 22 and the second conveying assembly 23 respectively. Each time an inner cover or an outer cover is received, the material collecting driving member 52 drives the material collecting member 51 to move, and the material collecting member 51 drives the material collecting frame 53 to shift, so that the receiving position of the material collecting frame 53 is in a vacant state to receive the next inner cover or outer cover.

[0137] The entire preparation process of the indoor unit shell, including raw material input, raw material melting, raw material injection molding, finished product demoulding, finished product removal and finished product transportation and stacking, is automated with a high degree of automation, reducing human interference or manpower input. The inner and outer covers are transported to the receiving area for receiving or assembly area for assembly via the same conveyor line, which significantly improves production efficiency and yield rate, and greatly reduces the labor requirement.
