Description

Technical Field

[0001] This utility model relates to the field of shell processing technology, specifically to an automated device for blowing and oiling shells. Background Technology

[0002] The technology of coating outer shells originated from the needs of industrial protection and precision manufacturing. In the early days, manual coating was used to prevent rust on metal parts. With the development of thinner and lighter electronic products and higher performance of automotive parts, traditional processes could not meet the requirements due to low efficiency and poor consistency. Automated coating technology achieves coating control through high-pressure atomization, electrostatic adsorption and other means. It has become a key process to improve product protection and reduce manufacturing costs in the fields of 3C electronics, automotive parts and home appliances, and continues to upgrade towards environmentally friendly oils and intelligent management.

[0003] In the prior art, during the transfer and storage of the shell to be coated, the surface of the shell is prone to the adhesion of debris, which affects the coating effect during the oiling process. In addition, it is inconvenient to cover the non-coated areas during the oiling process, and the oil tends to accumulate at the edges of the non-coated areas, forming irregular flow marks or oil droplet stains, which damages the uniformity of the product appearance. To address these issues, an automated device for blowing and oiling shells is proposed. Summary of the Invention

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] An automated device for blowing oil onto a housing includes a positioning mechanism, an oiling mechanism is disposed above the positioning mechanism, and the positioning mechanism includes a motor.

[0006] The positioning mechanism includes a placement platform. Limiting rails are fixedly installed on both sides of the rear end of the top surface of the placement platform. Limiting shafts are slidably connected to the inner side of each limiting rail. A lower pressure plate is fixedly installed on the limiting shafts on the same side, and the outer walls of the two lower pressure plates abut against each other.

[0007] The placement platform has a placement groove on its top surface, located below the two lower pressure plates.

[0008] Each of the two lower pressure plates has an inner groove for mounting, and a cover plate is movably mounted on the inner side of each of the two mounting grooves. A handle is fixedly connected to one side of the top surface of each of the two cover plates.

[0009] As a further embodiment of this utility model: a sliding groove is symmetrically provided in the middle of the back of the placement platform, and a motor is fixedly installed inside the placement platform and near the sliding groove.

[0011] As a further embodiment of this utility model: one end of each slider extends to the outside of the groove, and the outer wall of the slider is rotatably connected to a connecting rod, the top end of the connecting rod being rotatably connected to the upper limiting shaft.

[0012] As a further embodiment of this utility model: the oiling mechanism includes a top plate, and columns are fixedly connected to the bottom surface of the top plate around its perimeter. The bottom end of each column is fixedly connected to the top surface of the placement platform. An air supply pipe is fixedly installed in the middle of the top surface of the top plate. A fan is fixedly installed on the upper end of one side of the air supply pipe. The air outlet of the fan faces downward, and a dustproof net is fixedly installed on the outer wall of the fan near the air inlet.

[0013] As a further embodiment of this utility model: both sides of the outer wall of the air supply pipe are fixedly and connected to several branch pipes, each branch pipe is equidistant along the length of the air supply pipe, and the bottom of each branch pipe is connected to several blower nozzles, each blower nozzle is equidistant along the length of the branch pipe.

[0014] As a further embodiment of this utility model: an oil spray nozzle is fixedly installed on the bottom surface of the top plate and between adjacent branch pipes, and an oil delivery pipe is fixedly and continuously connected to the side of each oil spray nozzle.

[0015] The beneficial effects of this utility model are:

[0016] This utility model supports the oiling nozzle with a top plate and sets up a blower nozzle between adjacent oiling nozzles. The fan draws gas from outside the device into the air supply pipe, and the airflow passes through the branch pipe and blows the blower nozzle downwards to the shell to be coated, thereby removing the debris attached to the shell surface and helping to improve the oiling effect.

[0017] The shell to be painted is placed inside the placement slot on the top surface of the placement platform. A movable lower pressure plate is installed above the placement slot. When the lower pressure plate falls, it can position the shell inside the placement slot. The top of the lower pressure plate is provided with a mounting slot for a masking plate.

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1-5 As shown, an automated device for air-blowing and oiling a casing includes a positioning mechanism 1, with an oiling mechanism 2 positioned above the positioning mechanism 1. The positioning mechanism 1 includes a motor 104. The positioning mechanism 1 includes a placement platform 101, with limit rails 102 fixedly installed on both sides of the rear end of the top surface of the placement platform 101. Limit shafts 108 are slidably connected to the inner sides of each limit rail 102. Lower pressure plates 112 are fixedly installed on the limit shafts 108 on the same side, and the outer walls of the two lower pressure plates 112 abut against each other. A placement groove is formed on the top surface of the placement platform 101 below the two lower pressure plates 112. Mounting grooves 109 are formed on the inner sides of each of the two lower pressure plates 112, and cover plates 110 are movably installed on the inner sides of each of the two mounting grooves 109. A handle 111 is fixedly connected to one side of the top surface of each of the two cover plates 110. Figure 2 As shown, multiple shields 110 can be used in pairs, and each shield 110 is provided with a different width, which facilitates the restriction of the spraying area on the surface of the outer shell.

[0027] A sliding groove 103 is symmetrically provided in the middle of the back of the placement platform 101. One end of the placement platform 101, near the sliding groove 103, is fixedly installed with a motor 104. The output shaft of the motor 104 is fixedly connected to a lead screw 105. The other end of the lead screw 105 is rotatably connected to the inner wall of the placement platform 101. Threads are provided on both sides of the outer wall of the lead screw 105, with the threads on both sides facing opposite directions. Slider blocks 106 are threaded onto both sides of the outer wall of the lead screw 105. The outer walls of the sliders 106 are slidably connected along the inner side of the sliding groove 103. One end of each slider 106 extends to the outside of the sliding groove 103, and a connecting rod 107 is rotatably connected to the outer wall of the slider 106. The top end of the connecting rod 107 is rotatably connected to the upper limiting shaft 108. Figure 3 As shown, when the distance between the sliders 106 is shortened, the limiting shaft 108 and the lower pressure plate 112 are driven to fall through the connecting rod 107. When the distance between the sliders 106 is increased, the limiting shaft 108 and the lower pressure plate 112 are driven to rise through the connecting rod 107.

[0028] The oiling mechanism 2 includes a top plate 201, with columns 209 fixedly connected to all four sides of the bottom surface of the top plate. The bottom end of each column 209 is fixedly connected to the top surface of the placement platform 101. An air supply duct 202 is fixedly installed in the middle of the top surface of the top plate 201. A fan 203 is fixedly installed on the upper side of one side of the air supply duct 202. The air outlet of the fan 203 faces downward, and a dustproof net 204 is fixedly installed on the outer wall of the fan 203 near the air inlet. Figure 4 As shown, the dustproof mesh 204 prevents dust from entering the air supply duct 202;

[0029] Several branch pipes 205 are fixedly and continuously connected to both sides of the outer wall of the air supply duct 202. Each branch pipe 205 is equidistant along the length of the air supply duct 202, and several air blowing nozzles 206 are fixedly and continuously connected to the bottom of each branch pipe 205. Each air blowing nozzle 206 is equidistant along the length of the branch pipe 205. Oiling nozzles 207 are fixedly installed on the bottom surface of the top plate 201 between adjacent branch pipes 205. Each oiling nozzle 207 has an oil supply pipe 208 fixedly and continuously connected to its side. Figures 4-5 As shown, each side branch pipe 205 controls the airflow output of the two blower nozzles 206 below. The two branch pipes 205 located on the same straight line are isolated to avoid airflow from different directions from interfering with each other.

[0030] The working principle of this utility model:

[0031] When the device is in use, the shell to be sprayed is placed inside the placement groove on the surface of the placement platform 101. The airflow is driven by the fan 203, so the airflow passes through the air supply pipe 202 and the branch pipe 205, and finally the airflow is sprayed out onto the surface of the shell through the blower nozzle 206, and the debris attached to the surface of the shell is removed. Then, the motor 104 is started to drive the lead screw 105 to select. The threads on both sides of the surface of the lead screw 105 push different sliders 106 to move along the slide groove 103, and the two sliders 106 move in opposite directions. When the distance between the sliders 106 decreases, the limiting shaft 108 falls along the limiting rail 102 and drives the lower pressure plate 112 to press the top of the shell, thereby positioning the shell in the placement groove. Then, depending on the area of ​​the shell to be sprayed, a shield 110 of different widths can be placed in the mounting groove 109 to prevent the non-sprayed area of ​​the shell surface from being exposed under the oiling nozzle 207.

[0032] Secondly, the external pipeline inputs the spraying oil into the oil supply pipe 208, and finally sprays it onto the spraying area of ​​the outer shell through the oil spray nozzle 207.

[0033] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
