Detailed implementation manners
[0020] In order to make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0021] The present utility model will be further described below with reference to the embodiments.
[0022] Embodiment: Refer to Figures 1 to 3 , a dispensing device for producing mobile phone liquid crystal displays, including a workbench 1. A plurality of support legs are fixedly connected to the lower end of the workbench 1. An installation frame 2 is fixedly connected to the upper left end of the workbench 1. Two pairs of guide rods 3 are arranged at the right end of the installation frame 2. A mounting block 4 is slidably sleeved on the outer side of each pair of guide rods 3. Each pair of guide rods 3 is in damping sliding connection with the mounting block 4. By setting the mounting block 4 to slide horizontally on the rod body of the guide rod 3, the position of the following dispensing assembly can be adjusted, which is convenient for controlling the dispensing position and facilitating dispensing operations at different positions.
[0023] A dispensing assembly is arranged on the mounting block 4. The dispensing assembly includes a glue storage cylinder 5 fixedly connected to the mounting block 4. An electric dispensing head 6 is arranged at the lower end of the glue storage cylinder 5. The electric dispensing head 6 is a known technology in the art, and its specific structure and principle will not be elaborated in detail here.
[0024] At the upper end of the workbench 1, there are multiple limiting components arranged below the dispensing component. Specifically, the limiting component includes a negative pressure chamber 7 opened at the upper end of the workbench 1. A placement plate 8 is arranged on the upper side of the negative pressure chamber 7. Multiple micro-holes 9 communicating with the negative pressure chamber 7 are opened on the placement plate 8. A through-hole 10 communicating with the lower side of the negative pressure chamber 7 is also opened on the workbench 1. An air pump 11 is fixedly installed at the lower end of the workbench 1. An air suction pipe 12 is connected between the air pump 11 and multiple through-holes 10. Before dispensing, place the mobile phone liquid crystal display on the upper end of the placement plate 8. Start the air pump 11, and extract the gas in the negative pressure chamber 7 through the air suction pipe 12. A negative pressure condition is formed in the negative pressure chamber 7. On the one hand, the gas enters the negative pressure chamber 7 from the micro-holes not covered by the mobile phone liquid crystal display, making the gas in the negative pressure chamber 7 form a circulating negative pressure. On the other hand, the mobile phone liquid crystal display on the placement plate 8 is adsorbed on the upper end of the placement plate 8 through the micro-holes 9, avoiding the situation that the mobile phone liquid crystal display is prone to displacement during dispensing.
[0025] On the workbench 1, a curing component is also arranged to the right of the limiting component. Specifically, the curing component includes two vertical plates 13 symmetrically and fixedly connected to the upper end of the workbench 1. A horizontal pipe 14 is arranged between the two vertical plates 13. Multiple air outlet nozzles 15 are connected to the lower end of the horizontal pipe 14 in a communicating manner. An air outlet pipe 16 is connected between the horizontal pipe 14 and the air pump 11. The gas in the air outlet pipe 16 enters the horizontal pipe 14 and blows downward through the multiple air outlet nozzles 15 connected to the lower end of the horizontal pipe 14, enabling the mobile phone liquid crystal display just dispensed under the air outlet nozzles 15 to be quickly cured, facilitating subsequent processing.
[0026] A pushing component is also arranged at the upper end of the workbench 1. The pushing component includes a limiting groove 17 opened on the workbench 1. A reciprocating lead screw 18 is rotatably connected in the limiting groove 17. A rotating motor 19 for driving the reciprocating lead screw 18 to rotate is fixedly installed at the left end of the workbench 1. A threaded sleeve 20 is slidably sleeved on the outer side of the reciprocating lead screw 18. The shape of the limiting groove 17 is square, and the threaded sleeve 20 is slidably connected to the limiting groove 17, ensuring that the rotation of the reciprocating lead screw 18 can drive the threaded sleeve 20 to horizontally slide on the outer side of the reciprocating lead screw 18.
[0027] A push plate 21 is fixedly connected to the upper end of the threaded sleeve 20. When the dispensing of the mobile phone liquid crystal display is completed, first turn off the air pump 11, and then start the rotating motor 19 to drive the reciprocating lead screw 18 to rotate, driving the threaded sleeve 20 to horizontally slide to the right on the outer side of the reciprocating lead screw 18, driving the push plate 21 to push the mobile phone liquid crystal display to the right. When the mobile phone liquid crystal display is pushed to directly below the curing component, start the air pump 11 again, and the mobile phone liquid crystal display can be quickly air-dried and cured. At the same time, under the continuous operation of the rotating motor 19, the reciprocating lead screw 18 can rotate to drive the push plate 21 to slide leftward to reset, reducing the manual labor intensity.
[0028] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
