Description

Technical Field

[0001] The utility model belongs to the technical field of LED module production, and specifically relates to a LED module production spraying device. Background Art

[0002] LED modules need to be sprayed with conformal coating during production. Conformal coating can effectively isolate the circuit board and protect the circuit from erosion and damage in harsh environments. It has good adhesion, low stress, no corrosion to components, wide operating temperature range, and high softening point of the paint film. It has good stability to acid, alkali, salt and other chemical substances, can prevent leakage, has excellent resistance to salt spray, mildew and moisture, and forms a film quickly, thereby improving the reliability of the circuit board and increasing its safety factor.

[0003] Existing LED module painting equipment mostly uses conveyor belts to achieve continuous processing of multiple modules. Since the conveyor belt is constantly moving, workers do not have enough time to clamp the plates and can only clamp them quickly by the force of the spring, which leads to insufficient clamping force. Paint often falls off due to excessive impact force. At the same time, the existing device cannot control the distance between the nozzle and the product. The spray atomization area is too small, resulting in effective spraying and excessive impact force. Conversely, if it is too far, the atomized paint may spread outside the working area, causing pollution to the surrounding air. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a LED module production spraying device, which can realize automatic clamping or automatic loosening of the LED module board during the movement process, so as to facilitate loading and unloading while ensuring the stability of the board when entering the painting area to prevent the board from falling off due to impact.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] The top of the lifting board is provided with a spring, and one end of the spring contacts with the top of the lifting board.

[0007] Furthermore, guiding inclined surfaces are symmetrically provided on the top of the side where the fixed rubber pad and the movable block are close to each other.

[0008] Furthermore, a frame is installed on the top of the side plate by bolts, the frame spans above the conveyor belt, and a paint storage bucket is fixed on the top of the frame.

[0009] Furthermore, pump bodies are symmetrically arranged on both sides of the top of the frame, the input end of the pump body is connected to the interior of the paint storage bucket, connecting pipes are symmetrically installed on both sides of the frame surface, and the output end of the pump body is connected to the connecting pipes.

[0010] Furthermore, a double-threaded rod is horizontally installed on the top of the frame through a bearing, one end of the double-threaded rod passes through the side surface of the frame, and a control handwheel is provided at one end of the double-threaded rod, and the control handwheel is placed outside the frame.

[0011] Furthermore, a movable tube is symmetrically screwed on the surface of the double-threaded rod, a hose is connected to the bottom of the connecting tube, one end of the hose facing away from the connecting tube is connected to the top of the movable tube, the movable tube is vertically arranged, and nozzles are evenly arranged on the side where the two movable tubes are close to each other.

[0012] Compared with the prior art, the beneficial effects of the utility model are: the LED module board is evenly placed on the movable fixed block, and during the movement, the inner plate is clamped and fixed through the cooperation of the extrusion head and the limit strip, thereby improving the clamping force of the plate when it passes through the paint spraying area, and conversely, at the inlet and outlet ends, the clamping force is relaxed to facilitate loading and unloading. At the same time, the device can control the distance between the nozzles on both sides according to actual conditions to facilitate debugging. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0019] like Figure 1 and Figure 3 As shown, a LED module production spraying device comprises a lifting support frame 1, the top of the lifting support frame 1 is symmetrically provided with side panels 2, a conveyor belt 3 is installed between the two side panels 2, and the surface of the conveyor belt 3 is evenly provided with fixed blocks 4, the fixed blocks 4 are U-shaped and open at the top, a slide bar 8 is slidably penetrated on one side of the fixed block 4, the slide bar 8 is horizontally arranged, an extrusion head 9 is arranged at one end of the slide bar 8, and a movable block 11 is arranged at the other end of the slide bar 8, the end of the extrusion head 9 is hemispherical, and the extrusion head 9 is hemispherical. The pressure head 9 is placed on the outside of the fixed block 4, and a fixed rubber pad 7 is glued inside the side of the fixed block 4 facing away from the sliding rod 8. The fixed rubber pad 7 corresponds to the movable block 11. A spring 10 is sleeved on the surface of the sliding rod 8. The spring 10 is placed on the outside of the fixed block 4. One end of the spring 10 contacts the surface of the extrusion head 9. A limiting strip 5 is provided on the side of the upper surface of the side plate 2 close to the extrusion head 9. A buffer slope 6 is provided on the side of the limiting strip 5 close to the feeding end of the conveyor belt 3, and the end of the extrusion head 9 corresponds to the position of the limiting strip 5.

[0020] According to the above structure, before the fixed block 4 moves to the frame 13, the extrusion head 9 can be squeezed by the limiting strip 5 on one side, so that the movable block 11 moves toward the fixed rubber pad 7, thereby increasing the extrusion force on the plate at the center position to prevent loosening due to the impact force during painting. The movable block 11 is also supported by rubber material to prevent damage to the plate due to excessive extrusion force.

[0021] Among them, a guiding inclined surface 12 is symmetrically provided on the top of the side where the fixed rubber pad 7 and the movable block 11 are close to each other, so as to facilitate the installation of the plate and improve the efficiency of feeding.

[0022] like Figure 1 and Figure 2 As shown, a frame 13 is installed on the top of the side plate 2 by bolts, and the frame 13 spans above the conveyor belt 3. A paint storage bucket 14 is fixed on the top of the frame 13. Pump bodies 15 are symmetrically arranged on both sides of the top of the frame 13. The input end of the pump body 15 is connected to the inside of the paint storage bucket 14. Connecting pipes 18 are symmetrically installed on both sides of the surface of the frame 13, and the output end of the pump body 15 is connected to the connecting pipe 18. A double-threaded rod 16 is horizontally installed on the top of the frame 13 through a bearing. One end of the double-threaded rod 16 passes through the side surface of the frame 13, and a control hand wheel 17 is arranged at one end of the double-threaded rod 16. The control hand wheel 17 is placed on the outside of the frame 13. A moving tube 20 is symmetrically screwed on the surface of the double-threaded rod 16. A hose 19 is connected to the bottom of the connecting tube 18. The end of the hose 19 facing away from the connecting tube 18 is connected to the top of the moving tube 20. The moving tube 20 is vertically arranged, and nozzles 21 are evenly arranged on the side where the two moving tubes 20 are close to each other.

[0023] According to the above structure, the double-threaded rod 16 can be driven to rotate by the external control hand wheel 17, and then the distance between the two moving tubes 20 can be synchronously controlled, so as to flexibly adjust the impact force and spraying area of ​​the spraying on the middle plate, thereby improving the flexibility during use, and corresponding infrared sensing light curtains are installed on both sides of the inner wall on the front side of the frame 13 to judge whether the plate enters the interior of the frame 13.

[0024] The working principle of the utility model is as follows: the movement of the conveyor belt 3 can simultaneously drive multiple fixed blocks 4 to move. Due to the presence of the spring 10, the extrusion head 9 always has an outward force, which in turn separates the fixed rubber pad 7 and the movable block 11, and then places the module plate to be sprayed between the fixed rubber pad 7 and the movable block 11, and is guided by the guide slope 12 to facilitate entry and achieve preliminary fixation. When the corresponding fixed block 4 moves the limit strip 5 into the inner part, the extrusion head 9 can be squeezed to make the slide bar 8 approach the direction of the fixed rubber pad 7, and then the middle plate is clamped by the movable block 11 and the fixed rubber pad 7 to maintain stability during movement or painting. When it moves into the range of the frame 13, the pump body 15 can be started to inject high-pressure liquid into the mobile tube 20, and the paint liquid is evenly sprayed on the surface of the plate through multiple nozzles 21, and the distance between the two mobile tubes 20 can be adjusted according to the usage to improve practicality.

[0025] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded 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 field unless otherwise specified and limited.
