DETAILED DESCRIPTION

[0030] See also Figure 1-Figure 11 , an automatic spraying equipment for copper foil production, comprising a workbench 1, a transport assembly 2 is installed on the upper side of the workbench 1, a plurality of groups of paint cans 3 are evenly fixedly connected to the upper side of the workbench 1, a pump body for spraying paint is also installed inside the paint cans 3, a fixed pipe 4 is fixedly connected to the lower side of the plurality of groups of paint cans 3, a hose 5 is fixedly connected to the lower side of the fixed pipe 4, a paint spraying pipe 6 is fixedly connected to the lower side of the hose 5, a fixed plate 8 is fixedly sleeved on the outer side of the fixed pipe 4, a movable plate 11 is fixedly sleeved on the outer side of the paint spraying pipe 6, and a plurality of groups of first electro-hydraulic push rods 7 are fixedly connected between the fixed plate 8 and the movable plate 11;

[0031] First, the transport assembly 2 includes a power rod, a transport belt, etc. The copper foil to be painted is placed on the upper side of the transport belt, and the power rod is started. The power rod drives the transport belt to move, and the transport belt drives the copper foil to move until the copper foil completes the painting operation. Then, before the copper foil is painted, the corresponding paint is poured into the paint tank 3. When the copper foil needs to be painted, the first electro-hydraulic push rod 7 is started, and the first electro-hydraulic push rod 7 drives the moving plate 11 to move up and down. When the moving plate 11 reaches the lowest point, It will stagnate for a period of time. During this process, the copper foil is just located in front of the paint spraying tube 6. At this time, the paint spraying tube 6 is opened, and the copper foil continues to move. The material inside the paint tank 3 is sprayed out through the "fixed tube 4-hose 5-paint spraying tube 6" method and sprayed onto the copper foil, forming a painting operation on the copper foil. When the copper foil moves out from the lower side of the paint spraying tube 6, the paint spraying tube 6 stops spraying paint, and the first electro-hydraulic push rod 7 drives the moving plate 11 to move upward and return to its original position, which is convenient for the next painting operation. The above are all existing technologies and no unnecessary elaboration is made;

[0032] like Figure 2 , Figure 3 , Figure 8 A cleaning assembly 9 for cleaning excess material on the outer wall of the copper foil is installed on the lower side of the movable plate 11. The cleaning assembly 9 includes a cleaning cylinder 901, a mounting plate 912, and a blade 916. The number of cleaning cylinders 901 and blades 916 are multiple groups, and the cleaning cylinders 901 and blades 916 are arranged one by one in a relatively matched manner, that is, each cleaning cylinder 901 has and only has one blade 916 on the lower side, and a mounting rod 922 is fixedly connected to the upper side of the blade 916. The mounting rod 922 penetrates the lower wall of the cleaning cylinder 901 and is threadedly connected to the lower wall of the cleaning cylinder 901. The mounting plate 912 Multiple groups of transmission rods 910 are rotatably sleeved inside, and the multiple groups of transmission rods 910 are located on the upper side of the cleaning cylinder 901 and are matched with the cleaning cylinder 901 one by one, that is, each cleaning cylinder 901 has and has only one transmission rod 910 on the lower side, and the outer side of the multiple groups of transmission rods 910 is fixedly sleeved with a first gear 913, and the upper side of the mounting plate 912 is also rotatably connected to multiple groups of rotating rods 911, and the multiple groups of rotating rods 911 and the transmission rods 910 are staggered, and the outer side of the multiple groups of rotating rods 911 is fixedly sleeved with a second gear 925, and the first gear 913 and the second gear 925 are meshed;

[0033] First, in the process of the mounting plate 912 moving downward, the transmission rod 910 and the cleaning barrel 901 move downward as a whole. When the paint spraying tube 6 stops, the transmission rod 910 and the cleaning barrel 901 stop at the same time. Then, under the action of the first gear 913, the second gear 925 and the rotating rod 911, when one of the transmission rods 910 rotates, all other transmission rods 910 rotate at the same time, and the transmission rod 910 drives the cleaning barrel 901 and the blade 916 to rotate. Since the position of the blade 916 is in a fixed state at this time, and the copper foil moves with the transport component 2, the gap between the blade 916 on the upper side of the copper foil and the copper foil is small. If the paint on the upper side of the copper foil is thicker, it will form a cleaning effect on the paint, reducing the workload of the subsequent grinding operation, and before the copper foil is sprayed with paint for the first time, the blade 916 and the copper foil are offset, which can also form a simple cleaning operation on the copper foil, maintain the cleanliness of the copper foil, and thus ensure the painting effect (see below for subsequent processing operations of the paint).

[0034] like Figure 4 , Figure 5 , Figure 6 , Figure 8 , a square tube 909 is fixedly connected to the outside of one of the transmission rods 910, and a square rod 908 is slidably sleeved in the square tube 909, such as Figure 4 As shown, the cross-sectional shapes of the square tube 909 and the square rod 908 can be triangles, quadrilaterals, pentagons, etc., the upper side of the square rod 908 is fixedly connected with a rotating rod 907, the rotating rod 907 penetrates the moving plate 11 and is rotatably connected with the moving plate 11, the upper side of the moving plate 11 is fixedly connected with a motor 905, the output end of the motor 905 is fixedly connected with a rotating shaft, the rotating shaft is connected to the rotating rod 907 through a pulley assembly 906, the lower side of the moving plate 11 is fixedly connected with a driven plate 902 through a connecting rod, the outer side of the driven plate 902 is sleeved with two threaded rods 904, the two threaded rods 904 and The mounting plate 912 is fixedly connected, and multiple groups of nuts are threadedly sleeved on the outer sides of the two threaded rods 904. The multiple groups of nuts are located on the upper and lower sides of the driven plate 902 and are against the driven plate 902. Two cleaning plates 914 are installed between the blade 916 and the cleaning cylinder 901. The two cleaning plates 914 are symmetrically arranged on both sides of the mounting rod 922. The outer sides of the two cleaning plates 914 are slidably sleeved with a clamping rod 915. The clamping rod 915 is located on the lower side of the mounting plate 912 and is fixedly connected to the mounting plate 912. A feeding hole 921 is provided on the lower side of the cleaning cylinder 901, and an exhaust fan 923 is fixedly connected inside the cleaning cylinder 901.

[0035] First, if Figure 4, the pulley assembly 906 includes two rotating rods and a belt, wherein the two rotating rods are rotatably installed on the upper side of the movable plate 11, and the two rotating rods, the output shaft of the motor 905 and the rotating rod 907 are symmetrically arranged on the outside of the paint spraying tube 6, and the belt is sleeved on the two rotating rods, the output shaft of the motor 905 and the outside of the rotating rod 907, and the belt will not abut against the paint spraying tube 6, so the paint spraying tube 6 will not adversely affect the normal transmission of the pulley assembly 906. Secondly, during the painting process, start the motor 905, and the motor 905 drives the rotating rod 907 to rotate through the pulley assembly 906. The rotating rod 907 drives the transmission rod 910 to rotate through the square rod 908 and the square tube 909. The transmission rod 910 drives the cleaning tube 901 and the blade 916 to rotate. The blade 916 can clean the excess paint on the upper side of the copper foil. Since the cleaning plate 914 and the blade 916 abut against each other, the oil after cleaning Most of the paint accumulates on the front side of the cleaning plate 914. Starting the exhaust fan 923 can reduce the pressure inside the cleaning barrel 901, which can form an attraction effect on the paint. The paint enters the cleaning barrel 901 through the feed hole 921. Since the cleaning barrel 901 is in a rotating state during this process, under the action of centrifugal force, the paint will accumulate on the inner wall of the cleaning barrel 901 and will not be discharged from the discharge hole again, thereby completing the collection effect of excess paint. Secondly, before spraying, first move the mounting plate 912 up and down according to the actual working situation, adjust the distance between the mounting plate 912 and the driven plate 902, and then turn the nut to fix the threaded rod 904 and the driven plate 902 together. When there is a lot of paint inside the cleaning barrel 901, the spraying operation can be stopped. At this time, the paint is automatically discharged from the cleaning barrel 901 under the action of its own gravity and fluidity, and the discharged paint can be collected.

[0036] like Figure 7 The transmission rod 910 is provided with a moving control assembly of the cleaning barrel 901, and the moving control assembly includes a second electro-hydraulic push rod 917, which is fixedly mounted on the inner side of the transmission rod 910, and the output shaft of the second electro-hydraulic push rod 917 is fixedly connected to the cleaning barrel 901, and a moving ring 920 is fixedly sleeved on the outer side of the output shaft of the second electro-hydraulic push rod 917, and a fixed ring 919 is fixedly sleeved in the transmission rod 910, and the moving ring 920 is located at the lower side of the fixed ring 919 and abuts against the fixed ring 919, and a reset spring 918 is fixedly connected between the moving ring 920 and the transmission rod 910;

[0037] When the second electro-hydraulic push rod 917 is not started, under the action of the return spring 918, the movable ring 920 and the fixed ring 919 are against each other. When the second electro-hydraulic push rod 917 is started, the second electro-hydraulic push rod 917 will drive the cleaning cylinder 901 to move downward. During the downward movement of the movable plate 11, the second electro-hydraulic push rod 917 is in an open state. When the movable plate 11 stops moving, the second electro-hydraulic push rod 917 is started again. With the assistance of the return spring 918, the cleaning cylinder 901 and the blade 916 are driven to move upward relative to the paint spraying tube 6. The cleaning cylinder 901 and the side wall of the copper foil are against each other and move upward, forming a cleaning operation for the excess paint on the side wall of the copper foil. After the painting is completed, the second electro-hydraulic push rod 917 is started, and the second electro-hydraulic push rod 917 drives the cleaning cylinder 901 to move downward. The cleaning cylinder 901 is against the side wall of the copper foil again and moves downward relative to the paint spraying tube 6, thereby forming a cleaning operation for the excess paint on the front and back sides of the copper foil.

[0038] like Fig. 9 , Fig.10 , Fig.11, a clamping assembly 10 for clamping and fixing the copper foil is installed on the upper side of the workbench 1, and the clamping assembly 10 includes a placement plate 101, a third electro-hydraulic push rod 106, and a clamping plate 103. The number of the placement plates 101 is multiple groups, and the multiple groups of placement plates 101 are clamped on the upper side of the transport assembly 2. A slide groove is provided in the workbench 1, and the placement plates 101 are slidably connected to the slide groove. Two groups of vertical plates 102 are fixedly connected to the upper side of each placement plate 101. The number of the third electro-hydraulic push rods 106 is four, and the four third electro-hydraulic push rods 106 are located between the two vertical plates 102. There are multiple groups of clamping plates 103, one side of the multiple groups of clamping plates 103 is an arc-shaped setting, and the multiple groups of clamping plates 103 and the output ends of the third electro-hydraulic push rods 106 are fixedly connected; the two groups of vertical plates 102 are rotatably connected with the regulating rods 104, and the outer side of the regulating rods 104 is threadedly sleeved with two groups of threaded rings 105, and the two groups of threaded rods 904 and the third electro-hydraulic push rods 106 are fixedly connected;The internal threads of the two sets of threaded rings 105 are set in opposite directions. By rotating the regulating rod 104, the two threaded rings 105 can be moved towards or away from each other. The upper sides of the four third electro-hydraulic push rods 106 are fixedly connected to contact plates 107, and both sides of the driven plate 902 are fixedly connected to connecting rods 903. The lower sides of the two connecting rods 903 are fixedly connected to pressure sensors 924. The pressure sensor 924 is located on the upper side of the contact plate 107 and abuts against the contact plate 107. First of all, the pressure sensor 924 is a pressure-sensitive sensor commonly used in real life. When the pressure sensor 924 and the contact plate 107 are against each other, the internal pressure sensitive element generates an electrical signal and sends it to the controller, which controls the opening and closing of the second electro-hydraulic push rod 917. When the pressure sensor 924 is squeezed, the controller receives the signal to control the second electro-hydraulic push rod 917 to close. When the pressure sensor 924 is not squeezed, the second electro-hydraulic push rod 917 is opened. This is a common application method of sensors in real life, so no unnecessary details are given. A card block is provided on the upper side of the conveyor belt, and a card block is provided on the placement plate 107. The lower side of 1 is provided with a card slot opposite to the card block. When the copper foil needs to be sprayed, the copper foil is placed on the placement plate 101, and the regulating rod 104 is rotated. The regulating rod 104 drives the two third electro-hydraulic push rods 106 to move towards or away from each other through the threaded ring 105, until the third electro-hydraulic push rod 106 drives the clamping plate 103 to move towards or away from each other, until the contact plate 107 on the upper side of the third electro-hydraulic push rod 106 and the copper foil are at the same horizontal line, at this time, the third electro-hydraulic push rod 106 is started, and the third electro-hydraulic push rod 106 is turned to the left. 106 drives the clamping plate 103 to move, the clamping plate 103 clamps the copper foil, and then inserts the placement plate 101 into the slide slot, starts the transport component 2, when the clamping block and the slot are opposite, releases the placement plate 101, and the transport component 2 drives the placement plate 101 to move. When the copper foil moves to the front side of the paint spraying tube 6, the paint spraying tube 6 stops. At this time, the contact plate 107 and the pressure sensor 924 are against each other, and the second electro-hydraulic push rod 917 is closed. When the copper foil is sprayed, the contact plate 107 and the pressure sensor 924 are disconnected, and the second electro-hydraulic push rod 917 is started. ;

[0039] In the present invention, when it is necessary to spray paint the copper foil, the copper foil is placed on the placement plate 101, and the regulating rod 104 is rotated. The regulating rod 104 drives the two third electro-hydraulic push rods 106 to move in a direction close to or away from each other through the threaded ring 105, until the third electro-hydraulic push rod 106 drives the clamping plate 103 to move in a direction close to or away from each other, until the contact plate 107 on the upper side of the third electro-hydraulic push rod 106 and the copper foil are at the same horizontal line, at this time, the third electro-hydraulic push rod 106 is started, and the third electro-hydraulic push rod 106 drives the clamping plate 103 to move, and the clamping plate 103 clamps the copper foil, and then the placement plate 101 is inserted into the slide slot, and the transport component 2 is started. When the card block and the card slot are relative, the placement plate 101 is released, and the transport component 2 drives the placement plate 10 1 moves. Before the copper foil is sprayed with paint, the corresponding paint is poured into the paint tank 3. When the copper foil needs to be sprayed with paint, the first electro-hydraulic push rod 7 is started. The first electro-hydraulic push rod 7 drives the movable plate 11 to move up and down. When the movable plate 11 reaches the lowest point, it will stop for a period of time. During this process, the copper foil is just located in front of the paint spraying tube 6. At this time, the paint spraying tube 6 is opened, and the copper foil continues to move. The material inside the paint tank 3 is sprayed out through the "fixed tube 4-hose 5-paint spraying tube 6" method and sprayed onto the copper foil, forming a painting operation on the copper foil. When the copper foil moves out from the lower side of the paint spraying tube 6, the paint spraying tube 6 stops spraying paint, and the first electro-hydraulic push rod 7 drives the movable plate 11 to move upward and return to its original position to facilitate the next painting operation. When the copper foil moves to the spraying tube When the paint spraying tube 6 is in front of the paint spraying tube 6, the paint spraying tube 6 stops moving. At this time, the contact plate 107 and the pressure sensor 924 are against each other, and the second electro-hydraulic push rod 917 is started again. With the assistance of the return spring 918, the cleaning cylinder 901 and the blade 916 are driven to move upward relative to the paint spraying tube 6. The cleaning cylinder 901 is against the side wall of the copper foil and moves upward, forming a cleaning operation for the excess paint on the side wall of the copper foil. When the copper foil is finished painting, the contact plate 107 and the pressure sensor 924 are disconnected, and the second electro-hydraulic push rod 917 is started. The second electro-hydraulic push rod 917 drives the cleaning cylinder 901 to move downward. The cleaning cylinder 901 is against the side wall of the copper foil again and moves downward relative to the paint spraying tube 6, thereby forming a cleaning operation for the excess paint on the front and back sides of the copper foil, and at this During the process, the motor 905 is started, and the motor 905 drives the rotating rod 907 to rotate through the pulley assembly 906. The rotating rod 907 drives the transmission rod 910 to rotate through the square rod 908 and the square tube 909. The transmission rod 910 drives the cleaning tube 901 and the blade 916 to rotate. The blade 916 can clean the excess paint on the upper side of the copper foil. Since the cleaning plate 914 and the blade 916 are against each other, most of the cleaned paint is accumulated on the front side of the cleaning plate 914. The exhaust fan 923 is started to reduce the pressure inside the cleaning tube 901, which can form an attraction effect on the paint. The paint enters the cleaning tube 901 through the feeding hole 921. Since the cleaning tube 901 is in a rotating state during this process, under the action of centrifugal force,The paint will accumulate on the inner wall of the cleaning tube 901 and will not be discharged from the discharge hole again, thereby completing the collection effect of excess paint.
