DETAILED DESCRIPTION

[0021] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention.

[0022] As used herein, the terms "parallel," "perpendicular," and the like are not limited to their strict geometric definitions, but include tolerances for reasonable and inconsistent machining or human errors.

[0023] The technical solution provided by the present invention is as follows Figure 1 , 2 As shown in Figure 3, an additive uniform coating device for washing machine cover production includes a frame 10, on which a roller conveying mechanism for horizontally conveying a circular metal plate 00 for processing the cover is arranged, and an additive uniform distribution mechanism is arranged on the upper side of the conveying path of the roller conveying mechanism, and the additive uniform distribution mechanism uses a roller brush to apply additives to the upper surface of the circular metal plate 00. By applying the additives by roller brush, a uniform additive layer can be formed on the surface of the circular metal plate 00, and the coating amount of the additives can be well controlled, thereby facilitating the subsequent transfer of the circular metal plate 00 and avoiding the subsequent impact caused by excessive coating amount.

[0024] A further solution is: the additive uniform distribution mechanism includes an additive uniform distribution roller 30 located on the upper side of the roller conveying mechanism, the additive uniform distribution roller 30 is rotatably mounted on the frame 10, the length direction of the additive uniform distribution roller 30 matches the length direction of the conveying roller 11 on the roller conveying mechanism, and the outer surface layer of the coating conveying roller is composed of a liquid storage material that can absorb the additive. When this method is implemented, when the circular metal plate 00 passes from the lower side, the liquid storage material will be squeezed to make the additive inside seep out so as to evenly coat the upper surface of the circular metal plate 00 passing from the lower side, thereby improving the uniformity and efficiency of the circular metal plate coating additive. The additive uniform distribution roller 30 can be connected to a driving mechanism that adjusts it to rotate. It also includes a replenishment mechanism, which is used to add additives to the outer surface of the additive uniform distribution roller 30. Since the amount of additives adsorbed on the additive uniformly distributing roller 30 will decrease after the additives are coated, in order to achieve continuous production, it is necessary to continuously replenish the additives to the additive uniformly distributing roller 30 through a replenishing mechanism to ensure the reliability and continuity of production.

[0025] The detailed operation is as follows: it also includes a storage rack 22 for stacking and storing circular metal plates, and a feeding mechanism for transferring circular metal plates 00 is arranged between the storage rack 22 and the feeding end of the roller conveying mechanism. The feeding mechanism includes a feeding frame 21 arranged on the upper side of the roller conveying mechanism, and a feeding mounting seat 23 slidably installed along the length direction of the conveying roller 11 is arranged on the feeding frame 21, and a feeding grabbing mechanism for grabbing circular metal plates 00 is arranged on the feeding mounting seat 23. The feeding grabbing mechanism includes a feeding grabbing mounting frame, and the feeding grabbing mounting frame is lifted and installed on the feeding mounting seat 23, and each suspended vertically arranged feeding grabbing suction cup 24 is arranged on the feeding grabbing mounting frame, and the feeding grabbing suction cup 24 sucks and grabs each circular metal plate 00. During specific operation, the feed grabbing mounting frame can also be set to consist of an upper feed mounting frame and a lower feed mounting frame. The lower feed mounting frame is movably mounted on the upper feed mounting frame along the horizontal direction. The horizontal direction here can be one horizontal direction or multiple horizontal directions. The upper feed mounting frame is movably mounted on the feed grabbing mounting seat along the vertical direction. The feed grabbing suction cup 24 is mounted on the lower feed mounting frame. The movement of the feed grabbing mounting seat, the upper feed mounting frame and the lower feed mounting frame is adjusted by the set feed adjustment component to meet different material collection requirements. The storage racks 22 are respectively set on both sides of the roller conveying mechanism. Such a setting can avoid the situation where the machine needs to be stopped to load the round metal plate after the material collection is completed, thereby ensuring the reliability of the equipment operation.

[0026] A further solution is: the unloading end of the roller conveyor mechanism is provided with a blocking mechanism for blocking the movement of the circular metal plate 00 after the additive is evenly distributed, and a material transfer mechanism for transferring the circular metal plate 00 that has been blocked and moved into place to the next step for other processing. The setting of the blocking mechanism is to ensure the reliability of the material transfer mechanism in picking up materials, so that the position of the circular metal plate 00 that comes over each time is consistent, thereby realizing reliable material transfer to the subsequent step. The material transfer mechanism can be composed of a material transfer robot, and the mechanical arm of the material transfer robot is provided with a material transfer grabbing mechanism that is consistent with the structure of the feed grabbing mounting frame. Of course, it can also be implemented in a manner consistent with the feed mechanism, and the specific selection is made according to the actual situation. The roller conveying mechanism includes conveying rollers 11 arranged at intervals, and the limiting mechanism includes a limiting mounting block arranged in the middle of the corresponding conveying roller 11, and a limiting magnet 12 is installed on the limiting mounting block. The height of the limiting magnet 12 is greater than the height of the circular metal plate 00 when it is conveyed on the roller conveyor line. The limiting magnet 12 adsorbs the edge of the circular metal plate 00 when it abuts against the limiting mounting block and causes it to rise. Since the metal plate used to produce the cover plate is a circular metal plate 00, it is hindered by the limiting mechanism when the circular metal plate 00 moves to the unloading end. Since the driving action of the roller conveyor line is still in place, each circular metal plate 00 will move along the width direction of the roller conveyor line, resulting in inaccurate positioning and affecting the subsequent material transfer processing. At the same time, circular metal plates 00 of different sizes need to be limited by limiting mechanisms of different models or structures. By using the setting of the blocking magnet 12, after the circular metal plate 00 moves into place, the adsorption effect of the blocking magnet 12 causes the edge of the circular metal plate 00 to rise at a small angle, so that the driving force between the circular metal plate 00 and the roller conveying mechanism is weakened, and at the same time, the resistance of the circular metal plate 00 moving along the length direction of the conveying roller 11 is increased, so that the circular metal plate 00 cannot move, and can stay at the preset position according to the setting each time, ensuring the accuracy of subsequent transportation and other processing. At the same time, it can adapt to the blocking requirements of circular metal plates 00 of different sizes, and improve the scope of application and the reliability of blocking. The blocking magnet 12 is composed of a magnet block.

[0027] like Figure 3 As shown in the figure: a receiving groove 13 for receiving and recovering the dripping auxiliary agent is arranged on the lower side of the conveying roller 11, and a suspended curtain 14 is also arranged between the receiving grooves 13 of the roller conveying mechanism, and the curtain 14 is arranged to enclose the receiving groove 13. The curtain 14 is mainly arranged to prevent external dust from entering the receiving groove 13. A cover body 30 is arranged on the frame 10, and the replenishment mechanism and the auxiliary agent uniform distribution mechanism are both arranged in the cover body 30.

[0028] like Figure 4As shown in the figure, the replenishing mechanism is composed of replenishing units arranged at intervals along the length direction of the additive uniform distribution roller 30, and the replenishing units replenish the additive to different parts of the additive uniform distribution roller 30 respectively. The replenishing unit includes a replenishing tank 41 located beside the additive storage tank, and the lower part of the replenishing tank 41 is connected to the groove cavity of the additive tank 40 through a connecting pipe. The bottom of the replenishing tank 41 is connected to the replenishing needle 46 through a liquid outlet pipe 42. The replenishing needle 46 is vertically fixedly installed on the upper side of the additive uniform distribution roller 30, and the liquid outlet pipe 42 is provided with a replenishing needle 46. The regulator 43 is used to adjust the dripping speed of the needle 46. The liquid outlet pipe 42 is a soft plastic tube. The regulator 43 includes an adjustment seat arranged on the liquid outlet pipe 42, and a rotatably mounted adjustment cam 44 is arranged on the adjustment seat. The adjustment cam 44 is provided with a rotating handle 45. The adjustment cam 44 is rotated so that the outer peripheral surface of the adjustment cam 44 squeezes the tube body of the liquid outlet pipe 42 to deform, thereby adjusting the liquid outlet speed of the replenishment needle 46. The liquid outlet speed of each adjustment unit gradually decreases from the middle of the additive uniform distribution roller 30 to the two outer sides. The replenishment tank 41 can be made of transparent material, and a pressure regulating pipe joint is arranged on the upper end of the replenishment tank 41, and a regulating valve is arranged on the regulating pipe joint. The supply tanks 41 can be arranged in a staggered manner on both sides of the additive groove 40. A row of supply needles 46 are arranged on the lower side of the bottom of the additive groove 40. The supply needles 46 are connected to each supply tank 41 respectively. The cam 44 is rotated to adjust the outflow speed of each supply needle 46 to discharge liquid according to the preset. The supply needles are located on the upper side of the additive uniform distribution roller 30. Since the object to be coated is a circular metal plate, the coating area of ​​different sections of the additive uniform distribution roller 30 is different, resulting in different consumption of additives in different sections. Generally, the supply mechanism adds additives evenly, which will cause the coating amount of additives on the two sides of the circular metal plate 00 along the conveying direction of the roller conveying mechanism to be less than the coating amount in the middle. In the above scheme, by adjusting the dripping speed of the supply needle 46 corresponding to different sections, more consumption means more supply, less consumption means less supply, so that the additive content on each section of the uniform distribution roller 30 is consistent during each coating, and the additive is evenly coated on the surface of the circular metal plate along the length direction of the additive uniform distribution roller 30, thereby improving the coating uniformity.

[0029] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
