Description

[0002] Communication refers to the use of telecommunications equipment to transmit messages or audio, and sometimes also refers to transmission back and forth. With the continuous development and innovation of communication technology, more and more communication devices are used in daily life.

[0003] Currently, when communication devices are painted, in order to ensure the corrosion resistance and durability of the communication devices, the use strength of the communication devices is generally achieved by covering the coating with a combination of multiple paints. This makes the coating process on the surface of the communication devices more complicated, and it is necessary to wait until the previous paint spray is dry before spraying, resulting in low overall coating efficiency. In addition, the structural features of many communication devices (such as network bridges, pagers, and optical fiber fusion boxes) are generally wider on the front and back and narrower on the two sides. When spraying, if the single spraying area is large, when spraying the narrower two sides, it is easy to cause the spraying raw materials to escape and waste.

Therefore, an automatic coating equipment for communication devices is proposed. Summary of the invention

[0033] Example, see Figures 1 to 9 , an automatic coating equipment for communication devices, comprising a coating platform 1 and an outer cover 2 for separating a communication device 3, the top of the coating platform 1 is rotatably connected to a workpiece turntable 4 and a coating turntable 8, the top of the workpiece turntable 4 is provided with a plurality of positioning grooves and a negative pressure groove, the inner end surface of the positioning groove is connected to a positioning arc plate 6 for limiting the position of the communication device 3 through an electric push rod 5, and a negative pressure suction cup 7 is provided in the negative pressure groove;

[0034] Furthermore, the side wall of the coating platform 1 is fixedly connected to the inner wall of the outer cover 2, the positioning groove on the workpiece turntable 4 is adapted to the positioning arc plate 6, the inner end surface of the positioning groove is fixedly connected to the bottom end of the positioning arc plate 6 through the electric push rod 5, and the inner end surface of the negative pressure groove on the workpiece turntable 4 is fixedly connected to the bottom end of the negative pressure suction cup 7 through the vertical rod;

[0035] It should be noted that: the communication device 3 to be painted is vertically placed in a plurality of positioning arc plates 6 on the workpiece turntable 4, and the placement position of the communication device 3 is limited. During the placement process, the bottom end of the communication device 3 presses the negative pressure suction cup 7 to press out the air in the negative pressure suction cup 7 made of rubber material, thereby completing the adsorption and fixation of the communication device 3. After the fixation is completed, the positioning arc plate 6 is moved down and put into the positioning groove by contracting the electric push rod 5, so that the part of the communication device 3 to be painted is completely exposed;

[0036] The above advantages are: in this way, the extension of the positioning arc plate 6 can be used to facilitate the positioning of the communication device 3, and after the positioning arc plate 6 is retracted, it is convenient to subsequently paint the complete side of the communication device 3;

[0037] The top of the coating turntable 8 is connected to four paint storage chambers 10 through a hydraulic push rod 9, the bottom of the paint storage chamber 10 is connected to a right-angle nozzle 12 through a cone bucket 11, the horizontal end of the right-angle nozzle 12 is fixedly connected to an atomizing nozzle 13, the inner wall of the right-angle nozzle 12 is connected to a double-threaded groove shaft 15 through two mesh plates 14, and the outer wall of the double-threaded groove shaft 15 is connected to an impeller 18 through a spin component;

[0038] Furthermore, the top of the painting turntable 8 is fixedly connected to the bottom ends of four paint storage chambers 10 through a hydraulic push rod 9, and the bottom ends of the paint storage chambers 10 are interconnected with the vertical ends of the right-angle nozzles 12 through cone buckets 11. A hydraulic pump is arranged in the paint storage chamber 10, and the inner side walls of the horizontal sections of the right-angle nozzles 12 are respectively fixedly connected to the side walls of two mesh plates 14, and the two mesh plates 14 are respectively fixedly connected to the two ends of the double-threaded groove shaft 15, and the outer side wall of the end of the double-threaded groove shaft 15 away from the atomizing nozzle 13 is a smooth surface, and the spin assembly is composed of a collar 16 and a knob 17, and the inner side wall of the collar 16 close to the end of the atomizing nozzle 13 is fixedly connected to the knob 17, and the outer side wall of the collar 16 is fixedly connected to the inner side wall of the impeller member 18, and the knob 17 is slidably connected to the inner side wall of the spiral groove on the double-threaded groove shaft 15;

[0039] It should be noted that: during painting, as the hydraulic pump is started, the paint in the paint storage chamber 10 will be pressed into the right-angle spray pipe 12, and the primer epoxy varnish will be sprayed first. The liquid pumped into the right-angle spray pipe 12 will impact the impeller 18, causing the impeller 18 to rotate. The rotation of the impeller 18 will drive the collar 16 to rotate. The rotation of the collar 16 will drive the knob 17 to slide in the thread groove of the double-thread groove shaft 15, so that the impeller 18 moves synchronously in the double-thread groove shaft 15 during the rotation process. The impeller 18 rotates to stir the liquid in the right-angle nozzle 12, so that the liquid tends to move toward the periphery due to the centrifugal force, so that the mist paint sprayed by the atomizing nozzle 13 spreads toward the periphery. When the wide front and back surfaces of the communication device 3 are painted, the impeller 18 moves on the end close to the atomizing nozzle 13, so that the entire atomizing spraying area is larger, which is convenient for quickly spraying the front and back surfaces of the communication device 3. After the wide surface of the communication device 3 is sprayed, the workpiece turntable 4 is used to allow the communication device 3 to be sprayed. The communication device 3 is rotated 90 degrees to rotate the narrower side of the communication device 3 to one side of the atomizing nozzle 13 (the transformation of the wider side and the narrower side of the communication device 3 and the movement state of the impeller 18 approaching and moving away from the atomizing nozzle 13 are kept consistent and synchronous, ensuring the accurate and effective control of the paint spraying control). When the narrower sides of the communication device 3 are painted (it is particularly noted that the knob 17 on the inner wall of the impeller 18 moves to one end of the thread groove of the double-thread groove shaft 15, and then enters the other thread groove. The impeller 18 slides in the opposite direction in the groove, so that the impeller 18 can reciprocate and rotate on the double-thread groove shaft 15), and the impeller 18 has moved to one end away from the atomizing nozzle 13 (the flow rate of the paint in the right-angle nozzle 12 is controlled to be constant), so that the impeller 18 has less influence on the stirring of the sprayed atomized paint, thereby reducing the atomized spraying area and avoiding waste when painting a narrow surface. After the primer spraying is completed, the subsequent paint is applied in sequence by rotating the painting turntable 8 by 90 degrees;

[0040] The above advantages are as follows: the movement of the rotating impeller 18 on the double-threaded groove shaft 15 can be used to control the spray area of ​​the atomizing nozzle 13, and the coating of different surfaces of the communication device 3 can be automatically controlled, so that the coating efficiency of the wide surface is higher, and the waste of paint caused by the coating of the narrow surface is avoided. Since a combination of multiple paints is required for spraying, compared with the current method of constantly changing nozzles with different spray hole diameters to complete the spraying of wide and narrow surfaces, this method greatly improves the coating efficiency;

[0041] The outer side wall of the double-threaded groove shaft 15 away from the atomizing nozzle 13 is slidably connected with a moving ring 19, the outer side wall of the moving ring 19 is connected with an inner arc plate 20 through a fixed rod, the inner arc plate 20 is connected with an outer arc plate 21 through a sliding rod, the outer arc plate 21 is connected with a drying seat 24 through a deflection assembly, and the front side of the drying seat 24 is connected with a fan member 26 for air-drying the paint;

[0042] Furthermore, a plurality of outer arc grooves are provided on the side wall of the right-angle nozzle 12, and a slide groove is provided on the outer arc groove. The outer arc plate 21 is slidably connected to the inner wall of the outer arc groove, and the inner arc plate 20 is fixedly connected to the outer arc plate 21 through a slide rod. The side wall of the slide rod is slidably connected to the inner wall of the slide groove. The length of the inner arc plate 20 is greater than the length of the slide groove. The deflection assembly is composed of a universal rotating rod 22 and a support 23. The outer wall of the outer arc plate 21 is movably connected to one end of the support 23 through the universal rotating rod 22. Both ends of the universal rotating rod 22 are universal. The outer arc plate 21 is provided with a drying installation ring 27, the inner wall of the drying installation ring 27 is fixedly connected to the outer wall of the right-angle nozzle 12, the outer wall of the drying installation ring 27 is provided with a compensation ring groove, and a plurality of storage holes are provided on the compensation ring groove. The inner wall of the storage hole is rotatably connected to the support 23 through a rotating shaft, and the other end of the support 23 is fixedly connected to the side wall of the drying seat 24. The back of the drying seat 24 is fixedly connected with a driving motor 25, and the output end of the driving motor 25 is fixedly connected to the fan member 26 through a driving shaft;

[0043] It should be noted that: in the process of coating the communication device 3, multiple drive motors 25 on the right-angle nozzle 12 for spraying are started synchronously, driving multiple fan parts 26 to rotate synchronously to generate air-drying airflow. When the collar 16 moves to the movable ring 19, the movable ring 19 is squeezed and moved by the collar 16. The movement of the movable ring 19 drives the inner arc plate 20 to move through the fixed rod, thereby driving the outer arc plate 21 to move. The movement of the outer arc plate 21 drives one end of the universal rotating rod 22 to move, thereby utilizing the universal ball structure at the end of the universal rotating rod 22 to perform angle deviation. The universal rotating rod 22 is a telescopic rod structure with adjustable length. The displacement of the universal rotating rod 22 will drive the displacement of the support 23, thereby driving the entire drying seat 24 to deflect toward the center of the atomizing nozzle 13, so that the entire air-drying airflow is collected inward, which is convenient for collecting the air-drying airflow inward synchronously when the atomizing spraying area is reduced, so as to better air-dry the paint on the communication device 3 and facilitate the rapid subsequent paint coating. After the squeezing effect of the ring 16 disappears, the inner arc plate 20 is subjected to the thrust of the liquid flow and gradually drives the drying seat 24 to deflect and reset to the initial position;

[0044] The above advantages are: the deflection angle of the plurality of drying seats 24 can be changed to change the airflow drying range of the paint on the communication device 3, so that the paint can be dried quickly after coating, which is convenient for the subsequent coating of the next coat of paint, making the entire paint coating more efficient;

[0045] When the present invention is in use, the communication device 3 to be painted is vertically placed in a plurality of positioning arc plates 6 on the workpiece turntable 4, and the placement position of the communication device 3 is limited. During the placement process, the bottom end of the communication device 3 presses the negative pressure suction cup 7 to press out the air in the negative pressure suction cup 7 made of rubber material, thereby completing the adsorption and fixation of the communication device 3. After the fixation is completed, the positioning arc plate 6 is moved down and put into the positioning groove by contraction of the electric push rod 5, so that the part of the communication device 3 to be painted is completely exposed, so that the extension of the positioning arc plate 6 can be used to facilitate the positioning of the communication device 3, and after the positioning arc plate 6 is retracted, it is convenient to subsequently paint the complete side of the communication device 3;

[0046] During painting, as the hydraulic pump is started, the paint in the paint storage chamber 10 will be pressed into the right-angle nozzle 12, and the primer epoxy varnish will be sprayed first. The liquid pumped into the right-angle nozzle 12 will impact the impeller 18, causing the impeller 18 to rotate. The rotation of the impeller 18 will drive the collar 16 to rotate. The rotation of the collar 16 will drive the knob 17 to slide in the thread groove of the double-thread groove shaft 15, so that the impeller 18 moves synchronously in the double-thread groove shaft 15 during the rotation process. The rotation of the impeller 18 will stir the liquid in the right-angle nozzle 12, causing the liquid to move toward the periphery due to the centrifugal force. , so that the mist paint sprayed by the atomizing nozzle 13 diffuses to the periphery. When the wider surfaces of the front and back of the communication device 3 are painted, the impeller 18 moves on the end close to the atomizing nozzle 13, so that the entire atomizing spraying area is larger, which is convenient for quickly spraying the front and back of the communication device 3. After the wider surface of the communication device 3 is sprayed, the workpiece turntable 4 is used to rotate the communication device 3 ninety degrees, and the narrower surface of the communication device 3 is rotated to one side of the atomizing nozzle 13 (the transformation of the wider surface and the narrower surface of the communication device 3 and the movement state of the impeller 18 approaching and moving away from the atomizing nozzle 13 are kept consistent and changed synchronously, so as to ensure The control of the paint spraying is accurate and effective), when the narrower surfaces on both sides of the communication device 3 are painted (it is particularly noted that the knob 17 on the inner wall of the impeller 18 moves to one end of the thread groove of the double-thread groove shaft 15, and then enters the other thread groove to slide in the opposite direction, so that the impeller 18 can reciprocate and rotate on the double-thread groove shaft 15), the impeller 18 has moved to one end away from the atomizing nozzle 13 (the flow rate of the paint in the right-angle nozzle 12 is controlled to be constant), so that the impeller 18 has less effect on the stirring of the sprayed atomized paint, thereby reducing the atomization spraying area. , to avoid waste when painting narrow surfaces. After the primer is sprayed, the subsequent paints are applied in sequence by rotating the painting turntable 8 by 90 degrees. In this way, the movement and change of the rotating impeller 18 on the double-threaded groove shaft 15 can be used to control the spraying area of ​​the atomizing nozzle 13, and the painting of different surfaces of the communication device 3 can be automatically controlled, so that the wide surface painting efficiency is higher and the waste of paint caused by the narrow surface painting is avoided. Since a combination of multiple paints is required for spraying, compared with the current method of constantly changing nozzles with different spray hole diameters to complete the spraying of wide and narrow surfaces, this method greatly improves the painting efficiency;

[0047] In the process of coating the communication device 3, multiple drive motors 25 on the right-angle nozzle 12 for spraying are started synchronously, driving multiple fan parts 26 to rotate synchronously to generate air-drying airflow. When the collar 16 moves to the movable ring 19, the movable ring 19 will be squeezed and moved by the collar 16. The movement of the movable ring 19 will drive the inner arc plate 20 to move through the fixed rod, thereby driving the outer arc plate 21 to move. The movement of the outer arc plate 21 will drive one end of the universal rotating rod 22 to move, thereby utilizing the universal ball structure at the end of the universal rotating rod 22 to perform angle deviation. The universal rotating rod 22 is a telescopic rod structure with adjustable length. The deviation of the universal rotating rod 22 will drive the pillar 23 to deviate, thereby driving the entire The drying seat 24 is deflected toward the center of the atomizing nozzle 13, so that the entire air-drying airflow is collected inward, so that when the atomizing spray area is reduced, the air-drying airflow can be collected inward synchronously, so as to better air-dry the paint on the communication device 3 and quickly carry out the subsequent paint coating. After the squeezing effect of the ring 16 disappears, the inner arc plate 20 will gradually drive the drying seat 24 to deflect and reset to the initial position due to the thrust of the liquid flow. In this way, the deflection angle of multiple drying seats 24 can be changed to change the air-drying range of the paint on the communication device 3 by the airflow, so that the paint can be dried quickly after coating, which is convenient for the subsequent coating of the next coat of paint, making the entire paint coating efficiency higher.
