Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-7 The present invention provides the following technical solution: To address the problem in existing technologies where most systems use a single workstation, requiring machine stoppages during manual loading and unloading, thus affecting the efficiency of screen printing on mobile phone cases, this solution provides a multi-station automatic screen printing device for mobile phone case processing. The device comprises a fixed base 1, a positioning mold 9, and a screen printing machine body 16 positioned above the positioning mold 9. The positioning mold 9 has processing stations for placing mobile phone cases on its left and right sides. A horizontal drive assembly is located below the screen printing table 4, which moves the screen printing table 4 and the positioning mold 9 left and right below the screen printing machine body 16. Fixed side plates 7 are fixed to the front and rear sides of the upper end of the screen printing table 4, with the positioning mold 9 slidably and engagingly connected within the fixed side plates 7. The positioning mold 9 forms a detachable structure on the upper end of the screen printing table 4. like Figure 1 , Figure 4 and Figure 5 As shown, firstly, a positioning mold 9 of the corresponding specification is selected according to different collection models. A fixing post 10 is fixed in the middle of the positioning mold 9. At the same time, screw holes are opened on both the front and rear sides of the positioning mold 9. The positioning mold 9 is slid into the fixing side plate 7 from one side of the screen printing processing table 4. The arrow in the middle of the fixing side plate 7 points to the fixing post 10 to position the positioning mold 9 and the screen printing processing table 4. Then, the fastening bolt 11 is passed through the waist hole 8 and threaded into the screw hole to install and position the positioning mold 9. Moreover, the metal gasket 12 is tightly fitted to the end of the fastening bolt 11 and the upper end of the waist hole 8 to improve the fastening. The upper end of the positioning mold 9 is equipped with a double station. After installation, the phone case to be screen-printed is snapped into one of the stations, and the phone case abuts against the fixing post 10. Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7As shown, the second cylinder 14, which is installed on the top of the screen printing cover 13, is activated by an external controller. The second cylinder 14 drives the mounting plate 15 to move downward. The mounting plate 15 drives the screen printing machine body 16 to perform screen printing on the mobile phone case. The screen printing machine body 16 is a mature existing technology and is well known to those skilled in the art, so it will not be described in detail. At the same time, during the up and down movement of the mounting plate 15, the connecting rod 17 slides at the bottom of the screen printing cover 13, which improves the stability of the screen printing machine body 16 during the lifting process and avoids deviation. Moreover, during the screen printing process, another mobile phone case to be processed can be clamped on the other side of the positioning mold 9, without stopping the machine to wait during the loading or unloading process, thereby improving the efficiency of screen printing on the mobile phone case. After the screen printing of the phone case on one station is completed and the material loading on the other station is completed, the screen printing cover 13 moves the mounting plate 15 and the screen printing machine body 16 upwards. At the same time, through the setting of the horizontal drive component, which includes a first cylinder 2 installed at the right end of the fixed base 1, a connecting column 3 fixed to the output end of the first cylinder 2, a movable block 5 for limiting and a linear guide rail 6, the controller controls the start of the first cylinder 2 to drive the connecting column 3 to move relative to the fixed base 1. The connecting column 3 drives the screen printing processing table 4 to move above the fixed base 1. This causes the positioning mold 9 to move below the screen printing machine body 16 to switch the processing station. At the same time, the screen printing processing table 4 drives the movable block 5 to slide between the movable block 5 and the linear guide rail 6, improving the stability of the screen printing processing table 4 during the movement. Moreover, the linear guide rail 6 is equipped with a stop to prevent the movable block 5 from slipping off the linear guide rail 6. After the station switch is completed, the mobile phone case on the processing station is screen printed by the falling screen printing machine body 16. The processed mobile phone case on the other side is removed, and another mobile phone case to be processed is placed on the table. The above operation can be repeated.

[0017] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0018] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
