Description

Technical Field

[0001] The utility model relates to the technical field of notebook shell processing, and particularly relates to an automatic transmission induction device for spraying paint on a notebook shell. Background Technique

[0002] Spraying paint on a notebook shell is one of the key processes to improve the appearance texture and durability of the product. Through precise spraying technology, high-quality paint is evenly covered on the surface of the notebook shell, which not only endows it with bright colors and luster, but also can effectively resist scratches, fingerprints and slight impacts during daily use, protecting the internal precision components. The spraying process usually includes primer treatment to enhance adhesion, intermediate color paint application to achieve rich color effects, and topcoat spraying to increase gloss and wear resistance. The conveying device can convey the notebook shell to be sprayed for the spraying process.

[0003] The Chinese patent with the publication number CN214917472U discloses an automatic induction conveying device for a notebook computer spraying jig, which includes a plurality of legs fixedly installed on a spraying chamber. A conveying mechanism is installed on the spraying chamber, and a jig body is placed on the conveying mechanism. A paint storage chamber is fixedly installed on the spraying chamber, and two booster pumps are installed on the paint storage chamber. Two spraying plates are fixedly installed in the spraying chamber, and through pipes are connected between the two spraying plates and the two booster pumps. Through grooves matched with the jig body are arranged at both the left and right ends of the spraying chamber.

[0004] Although the above scheme can stop the operation of the conveying mechanism and start the booster pump when the jig body moves between the two spraying plates by using its gravity, the elastic characteristics of the conveyor belt mean that its deformation and relaxation degree may be affected by various factors, such as the weight of the notebook shell, the conveying speed, the aging degree of the conveyor belt, etc. These factors may lead to inaccurate detection and induction accuracy, so it does not meet the existing requirements. For this reason, we propose an automatic transmission induction device for spraying paint on a notebook shell. Content of the Utility Model

[0005] The purpose of the utility model is to provide an automatic transmission induction device for spraying paint on a notebook shell to solve the problem of inaccurate transmission and induction accuracy of the automatic transmission induction device during the spraying processing of the notebook shell as mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical scheme: an automatic transmission induction device for spraying paint on a notebook shell, including a main body. Conveyor rollers are rotatably arranged on the lower sides of both sides inside the main body, and a conveyor belt is connected between the conveyor rollers through transmission.

[0007] It also includes an infrared light curtain transmitter, which is installed at the rear side of the middle position inside the main body, and an infrared light curtain receiver is installed at the front side of the middle position inside the main body, and the infrared light curtain receiver is located directly in front of the infrared light curtain transmitter;

[0008] It also includes a fixed box, which is arranged on the outer wall of the conveyor belt, and a plurality of fixed boxes are evenly distributed. A double-threaded transmission rod is rotatably arranged at the middle position inside the fixed box, and both sides of the outside of the double-threaded transmission rod are threadedly connected with clamping blocks, one end of the clamping blocks extends to the outside of the fixed box, and the clamping blocks are slidably matched with the fixed box.

[0009] Preferably, a PLC controller is installed at the front end of the main body, and the input end of the PLC controller is electrically connected to the output end of the infrared light curtain receiver.

[0010] Preferably, motors are installed on both sides of the rear end of the main body, and the output ends of the motors are transmission-connected to the conveying rollers through couplings, and the input ends of the motors are electrically connected to the output ends of the PLC controller.

[0011] Preferably, guide rods are adhesively fixed to the front and rear sides of the interior of the fixing box, the guide rods pass through the clamping block, and the guide rods are slidably matched with the clamping block.

[0012] Preferably, both ends of the double-threaded transmission rod are provided with a rotating shaft, one end of the rotating shaft extends to the outside of the fixed box, and the rotating shaft is rotatably matched with the fixed box, and one end of the rotating shaft located outside the fixed box is installed with a knob.

[0013] Preferably, a rubber pad is adhesively fixed to the inner side of one end of the clamping block located outside the fixing box.

[0014] Preferably, a paint box is provided at the middle position of the rear end of the main body, a booster pump is provided at the middle position of the upper end of the main body, a paint hood is provided at the upper end inside the main body, and the booster pump is connected to the paint hood and the paint box through a connecting pipe.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. In this utility model, an infrared light curtain emitter is installed at the rear side inside the main body, and an infrared light curtain receiver is installed in front of the infrared light curtain emitter. When the motor is started to drive the conveyor belt to rotate, the notebook housing can be driven to move synchronously. When the notebook housing moves between the infrared light curtain emitter and the infrared light curtain receiver, the notebook housing will block the reception of the infrared light curtain receiver. At this time, the current of the infrared light curtain receiver will change, and thus an electrical signal will be sent to the PLC controller. After being processed by the PLC controller, the rotation of the motor will be stopped, and the booster pump will be started for the painting operation, thereby avoiding being affected by the elasticity of the conveyor belt itself and ensuring the accuracy of induction during transmission.

[0017] 2. In this utility model, a fixed box is provided on the outer wall of the conveyor belt. After placing the notebook housing on the upper end of the fixed box, the knob can be rotated. The knob will drive the double-threaded transmission rod to rotate through the rotating shaft, thereby driving the two clamping blocks to move horizontally in opposite or opposite directions, so that the placed notebook housing can be clamped and fixed, ensuring the stability and safety of the notebook on the conveyor belt, and avoiding slipping or damage caused by jolting or accidental touch during transportation or processing.

[0018] 3. In this utility model, a rubber soft pad is adhesively fixed to the inner wall of the clamping block. The rubber soft pad has good elasticity and shock absorption performance. When the notebook housing is clamped, it can absorb the vibration and impact force generated by the clamping action or the movement of the conveyor belt, effectively reducing the direct impact on the notebook housing and avoiding scratches or damages that may be caused by hard contact. At the same time, the sticky surface of the rubber soft pad can increase the friction force with the notebook housing, making the clamping more firm and stable. Even when the conveyor belt is running at high speed or encountering jolts, the notebook housing can maintain a stable clamping state and is not easy to slip or shake. Description of the Drawings

Detailed implementation manner

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1-4 , the present invention provides a technical solution: an automatic transmission induction device for spraying paint on a notebook shell, including a main body 1. Conveyor rollers 7 are rotatably arranged on the lower sides of both sides inside the main body 1, and the conveyor rollers 7 are drivingly connected by a conveyor belt 8;

[0026] It further includes an infrared light curtain emitter 9, which is installed at the rear side of the middle position inside the main body 1, and an infrared light curtain receiver 10 is installed at the front side of the middle position inside the main body 1, and the infrared light curtain receiver 10 is located directly in front of the infrared light curtain emitter 9;

[0027] It further includes a fixed box 12, which is arranged on the outer wall of the conveyor belt 8, and a plurality of fixed boxes 12 are equidistantly distributed. A double-threaded drive rod 13 is rotatably arranged at the middle position inside the fixed box 12. Clamping blocks 16 are threadedly connected to both sides of the outside of the double-threaded drive rod 13. One ends of the clamping blocks 16 extend to the outside of the fixed box 12, and the clamping blocks 16 are all slidably matched with the fixed box 12.

[0028] During use, the notebook shell is placed on the upper end of the fixed box 12. Rotate the knob 15 to drive the rotating shaft 14 and the double-threaded drive rod 13, so that the clamping blocks 16 move towards each other to clamp the shell. The rubber soft pad 17 protects the shell from abrasion. The motor 6 drives the conveyor roller 7 and the conveyor belt 8 to convey the shell to the infrared light curtain area. When the shell blocks the infrared rays, the PLC receives the signal and pauses the motor 6, starts the booster pump 4, and the paint goes from the paint tank 3 through the connecting pipe 5 to the spray paint hood 11 for spraying. At this time, the knob 15 can be rotated in the reverse direction to take the material, and at the same time, the material is continuously fed at the other end. After the spraying is completed, the motor 6 restarts to continue the conveying process.

[0029] Please refer to Figure 1 and Figure 3, a PLC controller 2 is installed at the front end of the main body 1, and the input end of the PLC controller 2 is electrically connected to the output end of the infrared light curtain receiver 10. The PLC controller 2 can receive the signal of the infrared light curtain receiver 10 in real time, respond quickly and control the working process of the equipment;

[0030] Please refer to Figure 1 and Figure 3 , motors 6 are installed on both sides of the rear end of the main body 1, and the output ends of the motors 6 are all connected to the conveyor rollers 7 through couplings. The input ends of the motors 6 are electrically connected to the output end of the PLC controller 2. The motors 6 can drive the conveyor rollers 7 to rotate stably and efficiently, thereby driving the conveyor belt 8 to move and realizing the continuous conveying of the notebook shell;

[0031] Please refer to Figure 4 , guide rods 18 are adhesively fixed to the front and rear sides inside the fixed box 12. The guide rods 18 all pass through the clamping blocks 16, and the guide rods 18 are all slidably matched with the clamping blocks 16. The guide rods 18 provide a stable moving track for the clamping blocks 16, ensuring that the clamping blocks 16 can be converted into horizontal linear movement during rotation, so as to realize the stable clamping of the notebook shell;

[0032] Please refer to Figure 2 and Figure 4 , both ends of the double-threaded transmission rod 13 are provided with rotating shafts 14. One end of each rotating shaft 14 extends to the outside of the fixed box 12, and the rotating shafts 14 are all rotatably matched with the fixed box 12. Knobs 15 are installed at one end of the rotating shafts 14 located outside the fixed box 12. By rotating the knobs 15, the rotating shafts 14 and the double-threaded transmission rod 13 can be easily driven to rotate, thereby realizing the synchronous movement of the clamping blocks 16, with simple operation and high efficiency;

[0033] Please refer to Figure 4 , rubber soft pads 17 are adhesively fixed to the inner sides of one end of the clamping blocks 16 located outside the fixed box 12. The rubber soft pads 17 can increase the friction between the clamping blocks 16 and the notebook shell, improve the stability of clamping, and the rubber material can buffer the impact force during clamping and protect the notebook shell from damage;

[0034] Please refer to Figure 1 and Figure 3 , a paint box 3 is arranged at the middle position of the rear end of the main body 1, a booster pump 4 is arranged at the middle position of the upper end of the main body 1, a paint spraying hood 11 is arranged at the upper end inside the main body 1, and the booster pump 4 is connected to the paint spraying hood 11 and the paint box 3 through connecting pipes 5. The booster pump 4 can stably provide the pressure required for paint spraying, ensuring that the paint can be evenly and quickly sprayed onto the notebook shell. The design of the paint spraying hood 11 can limit the paint spraying range and improve the precision and efficiency of paint spraying.

[0035] Working principle: When in use, place the notebook housing from the opening at one end of the main body 1 on the upper end of the fixed box 12. As the knob 15 is grasped and rotated, the knob 15 drives the rotation of the rotating shaft 14, and the rotating shaft 14 drives the synchronous rotation of the double-threaded drive rod 13. The double-threaded drive rod 13 drives the synchronous rotation of the two clamping blocks 16. Since the clamping blocks 16 are all slidably engaged with the two guide rods 18, the rotation of the clamping blocks 16 will be axially limited. The rotation of the two clamping blocks 16 will be converted into horizontal linear movement in opposite or opposite directions. When the two clamping blocks 16 move towards each other, they can clamp and fix the notebook housing placed in the middle, which can prevent the notebook housing from falling and moving during movement, ensuring the accuracy during painting. At the same time, by setting the rubber soft pad 17, the notebook housing can be protected to avoid abrasion during clamping and fixing, and the stability during clamping and fixing is also increased. Start the motor 6, and through the coupling, it will drive the rotation of the conveyor roller 7. The rotation of the two conveyor rollers 7 can drive the synchronous rotation of the conveyor belt 8, so as to convey the fixed box 12 and the fixed notebook housing. When the notebook housing moves between the infrared light curtain emitter 9 and the infrared light curtain receiver 10, the notebook housing will block the infrared light curtain emitted by the infrared light curtain emitter 9, so that the infrared light curtain receiver 10 cannot receive it. The infrared light curtain receiver 10 will generate an electrical signal and transmit it to the PLC controller 2. After processing by the PLC controller 2, the motor 6 will be stopped for a period of time. During this time, the booster pump 4 will be started, so that the paint in the paint tank 3 enters the paint spraying hood 11 through the connecting pipe 5 to spray the notebook housing below. At this time, the operator at the discharge port can rotate the knob 15 in the reverse direction to take out the notebook housing, and the operator at the feed port continues to place the notebook housing. After the painting is completed, the motor 6 is started, so that the conveying can continue.

[0036] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, it is intended to embrace all changes falling within the meaning and scope of the equivalent elements of the claims in the present invention. Any reference signs in the claims should not be regarded as limiting the claims involved.
