Embodiment 1

[0046] Embodiment 1, with reference to figure 1 As shown, the embodiment of the present invention provides a control method for dry ice cleaning mobile phone case, including the following steps:

[0047] Step 1. Determine the number of spray guns and cleaning parameters in the cleaning equipment according to the burrs on the mobile phone case to be cleaned, wherein the cleaning equipment includes a cleaning assembly line and a cleaning host, and a cleaning device is arranged on the cleaning assembly line. The cleaning device is provided with a plurality of spray guns for spraying dry ice, and the cleaning host provides solid dry ice particles for the spray guns. Wherein, the mobile phone case is a mainstream mobile phone case of 5-7 inches in the market, and the material of the spray gun is stainless steel or alloy material.

[0048] Optionally, the cleaning host includes a hopper, an ice crushing device, and a mixing device. The dry ice enters the ice crushing device through...

Embodiment 2

[0068] The embodiment of the present invention provides a control method for dry ice cleaning mobile phone case, using the following dry ice cleaning machine:

[0069] refer to image 3 , 4 As shown, this embodiment provides a dry ice blasting machine, including: a frame 1 , a cleaning line 2 , a cleaning host 3 and a controller 4 . By adopting an independent modular design, each module is independently installed at each position of the rack 1 and can be disassembled and replaced independently.

[0070] The frame 1 is used to provide a working chamber to support the dry ice blasting machine.

[0071] optional, see Figure 3-8 As shown, the frame 1 as a whole is constructed of aluminum alloy profiles, and has a plurality of cabinets made of stainless steel wire drawing sheet metal. The cleaning assembly line 2 and the cleaning host 3 are respectively installed in the cabinets. Modules are designed with disassembly handles and ventilation channels.

[0072] The cleaning lin...

Abstract

The invention provides a control method for mobile phone shell cleaning by using dry ice. The control method comprises the following steps that S1, according to the burr situation of to-be-cleaned mobile phone shells, the starting number and cleaning parameters of spray guns in cleaning equipment are determined, wherein the cleaning equipment comprises a cleaning assembly line and a cleaning mainmachine, cleaning devices are arranged on the cleaning assembly line, the plurality of spray guns used for jetting the dry ice are arranged on the cleaning devices, and the cleaning main machine provides solid dry ice particles for the spray guns; S2, the to-be-cleaned mobile phone shells are fixed to clamping devices on the cleaning assembly line, and the plurality of cleaning devices and cleaning main machines are arranged along the cleaning assembly line, wherein each clamping devices comprises a fixed support, an adjustable support and a plurality of limiting support blocks fixed on the assembly line; S3, the spraying directions and the spraying positions of the spray guns are adjusted; and S4, the cleaning assembly line is started. According to the control method, the cleaning efficiency of the mobile phone shells is improved, and relatively high economic efficiency and market value are achieved.

Description

technical field [0001] The invention relates to the technical field of dry ice cleaning of precision structural parts, in particular to a control method for dry ice cleaning of mobile phone cases. Background technique [0002] At present, in the production process of mobile phone cases, a large amount of oil and burrs will be generated, which is difficult to clean. The cleaning process is an important part of the production process. The current method is mainly to perform multiple repeated cleaning operations on the surface dirt of the cleaning workpiece through manual hand-held spray guns. Due to the mass production of mobile phone cases, manual cleaning is not only ineffective and affects product quality, but also inefficient and increases labor costs. The existing cleaning is mainly water washing. In order not to affect the product quality, water washing is often performed multiple times. Water washing is a process that consumes a lot of water, which wastes a lot of wate...
