Description

Technical Field

[0001] The invention relates to the field of circuit board gluing, in particular to a circuit board gluing device for sensor production. Background Art

[0002] Gluing of circuit boards is a common electronic manufacturing process. Its main purpose is to protect electronic circuit boards and their components from environmental factors, mechanical damage, corrosion, moisture, chemicals, etc., thereby improving the reliability and life of circuit boards. Gluing usually uses a specific coating or adhesive, which is evenly applied to the surface of the circuit board to form a protective film. In summary, gluing of circuit boards is a protective process commonly used in the electronic manufacturing process. By applying appropriate materials, it provides environmental protection, mechanical protection and electrical insulation, extending the service life and reliability of circuit boards.

[0003] The existing circuit board gluing devices cannot achieve a good uniform spraying effect during use. Most of them adopt manual spreading operations, which is time-consuming and labor-intensive. However, when using a machine to apply glue, the brush plate will bring out a large amount of glue from the circuit board, which not only affects the gluing quality but also makes the brush plate unable to be used normally after a large amount of glue adheres to it and solidifies. The spray nozzle is easily exposed to air, which can easily cause solidification inside. Not only that, the transportation of glue will also produce bubbles, which reduces the spraying quality. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the background technology and to propose a circuit board gluing device for sensor production.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: a circuit board gluing device for sensor production, comprising: a shell assembly, a conveyor, and support rods fixedly installed on both sides of the conveyor, a circuit board is arranged on the top of the conveyor, a control console is arranged on the right side of the conveyor, a first connecting pipe is fixedly installed on the top of the control console, and a regulating valve is fixedly installed on the end of the first connecting pipe; a gluing assembly, comprising a glue storage tray arranged above the circuit board, a rack is fixedly installed on the rear side of the glue storage tray, a bottom plate is fixedly installed on the top of the support rod, a hollow tube is rotatably installed in the middle of the bottom end of the bottom plate, and a gear is fixedly installed in the middle of the hollow tube; and a nozzle assembly, comprising a plurality of groups of multi-section nozzles fixedly installed on the bottom of the glue storage tray, a plurality of groups of servo motors are fixedly installed on the top of the glue storage tray, a rotating rod is fixedly installed on the output end of the servo motor, and a first ball, a second ball and a third ball are fixedly installed on the bottom end of the rotating rod respectively.

[0006] Preferably, support frames are fixedly installed on the left and right sides of the bottom end of the conveyor.

[0007] A servo motor is fixedly installed on the left side of the top of the base plate, a first chain disc is fixedly installed on the output end of the servo motor, a second chain disc is rotatably installed on the right end of the base plate, the first chain disc and the second chain disc are connected by a chain, and a third chain disc is meshed and installed in the middle of the chain.

[0008] Preferably, a slide groove tube is fixedly installed on the top of the base plate, a slide rod is fixedly installed inside the slide groove tube, a slider is slidably installed in the middle of the slider, and the top end of the third chain plate is rotatably connected to the slider.

[0009] Preferably, a first connecting rod is fixedly installed in the middle of the sliding block, a second connecting pipe is fixedly installed on the front side of the first connecting rod, the top of the second connecting pipe is connected to the regulating valve, and the bottom of the second connecting pipe is connected to the glue storage tray.

[0010] Preferably, a first slide groove and a second slide groove are respectively arranged inside the hollow tube, the first slide groove and the second slide groove are connected, and a vertical slide groove is connected between the first slide groove and the second slide groove.

[0011] Preferably, a spring and a telescopic rod are rotatably installed on the inner top of the hollow tube respectively, a rotating shaft is fixedly installed on the bottom end of the spring and the telescopic rod, a ball is fixedly installed on the middle part of the rotating shaft, the ball slides in the slide groove, a second connecting rod is fixedly installed on the bottom end of the rotating shaft, a brush plate is fixedly installed on the bottom end of the second connecting rod, and bristles are installed at the bottom end height of the brush plate.

[0012] Preferably, a filter disc is fixedly mounted on the rear side of the top end of the conveyor, and the bristles slide in the filter disc.

[0013] Preferably, the multi-section nozzle is divided into three layers, namely, upper, middle and lower layers, and the diameter of each layer decreases successively. The lengths of the first ball, the second ball and the third ball respectively correspond to the diameter of each section of the multi-section nozzle. The first ball is provided with two groups of warps, and the second ball and the third ball are provided with one group of warps.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The chain drives the movement of the third chain plate, so that it sprays glue from the multi-section nozzle while performing left and right reciprocating motion, so that when the circuit board is transported backward, the glue can be sprayed on the circuit board by sliding left and right, achieving a uniform spraying effect. While the circuit board continues to be transported backward, the rack drives the gear to rotate the hollow tube, and the ball in the hollow tube will first slide in the slide groove. The sliding of the ball makes the brush plate move up and down, and the bristles on the brush plate can spread the sprayed glue on the circuit board. At the same time, the movement of the brush plate makes the bristles constantly slide on the filter plate, squeezing the glue attached to the bristles back onto the circuit board, preventing the bristles from bringing out too much glue, and also preventing too much glue from solidifying on the bristles and affecting use.

[0015] During the spraying process, the servo motor drives the first ball, the second ball and the third ball to rotate on the circular inner wall of the multi-section nozzle. Since the air can easily enter the nozzle to solidify the glue, the balls can not only effectively scrape the glue attached to the inner wall for reuse and prevent solidification, but also slowly stir the glue entering the multi-section nozzle, making the internal glue more substantial, reducing the generation of bubbles and improving the quality of spraying.

DETAILED DESCRIPTION

[0018] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0019] like Figure 1 - Fig. 9 A circuit board gluing device for sensor production is shown, including a shell assembly 100, a conveyor 101, and support rods 102 fixedly installed on both sides of the conveyor 101, a circuit board 104 is arranged on the top of the conveyor 101, a control console 105 is arranged on the right side of the conveyor 101, a first connecting pipe 106 is fixedly installed on the top of the control console 105, a regulating valve 107 is fixedly installed on the end of the first connecting pipe 106, support frames 103 are fixedly installed on the left and right sides of the bottom end of the conveyor 101, the circuit board 104 is transported by the conveyor 101, and the control console 105 transports the glue to the glue storage tray 212.

[0020] The glue coating component 200 includes a glue storage tray 212 arranged above the circuit board 104, a rack 213 is fixedly installed on the rear side of the glue storage tray 212, a bottom plate 201 is fixedly installed on the top of the support rod 102, a hollow tube 214 is rotatably installed in the middle of the bottom end of the bottom plate 201, and a gear 215 is fixedly installed in the middle of the hollow tube 214. When the circuit board 104 continues to be transported backward, the movement of the glue storage tray 212 drives the rack 213 to drive the gear 215, so that the hollow tube 214 rotates, a servo motor 202 is fixedly installed on the left side of the top of the bottom plate 201, and a first chain disk 203 is fixedly installed on the output end of the servo motor 202, and a second chain disk 204 is rotatably installed on the right end of the bottom plate 201. The first chain disk 203 and the second chain disk 204 are rotatably installed. The disks 204 are connected by a chain 205, and a third chain disk 206 is meshed and installed in the middle of the chain 205. Under the drive of the servo motor 202, its output end drives the first chain disk 203 to rotate forward and reversely. The first chain disk 203 cooperates with the chain 205 and the second chain disk 204 to make the third chain disk 206 move left and right in the bottom plate 201. A slide tube 208 is fixedly installed on the top of the bottom plate 201, and a slide rod 209 is fixedly installed inside the slide tube 208. A slider 207 is slidably installed in the middle of the slider 209. The top of the third chain disk 206 is rotatably connected to the slider 207, and a first connecting rod 210 is fixedly installed in the middle of the slider 207. The front side of the first connecting rod 210 is fixedly installed with a second connecting tube 211. The top of the connecting pipe 211 is connected to the regulating valve 107, the bottom of the second connecting pipe 211 is connected to the glue storage tray 212, and the movement of the third chain plate 206 causes the slider 207 to drive the first connecting rod 210 to slide on the sliding rod 209. The sliding of the first connecting rod 210 drives the movement of the glue storage tray 212, so that it can spray glue from the multi-section nozzle 301 while performing left and right reciprocating motion, so that when the circuit board 104 is transported backward, the glue can be sprayed on the circuit board 104 by sliding left and right, achieving a uniform spraying effect. The interior of the hollow tube 214 is respectively provided with a first slide groove 221 and a second slide groove 222, the first slide groove 221 and the second slide groove 222 are connected, and the first slide groove 221 and the second slide groove 222 are connected. The vertical slide groove 223 and the inner top of the hollow tube 214 are rotatably installed with a spring 217 and a telescopic rod 216 respectively. The bottom ends of the spring 217 and the telescopic rod 216 are fixedly installed with a rotating shaft 218. The middle part of the rotating shaft 218 is fixedly installed with a ball 219. The ball 219 slides in the slide groove. The ball 219 in the hollow tube 214 will first slide in the first slide groove 221. When the rack 213 no longer drives the gear 215, the ball 219 will slide back to the top in the vertical slide groove 223 due to the elastic force of the spring 217. When the rack 213 drives the gear 215 in the reverse direction, the ball 219 will slide in the second slide groove 222, and then return to the top through the vertical slide groove 223. The bottom end of the rotating shaft 218 is fixedly installed with a second connecting rod 220.A brush plate 224 is fixedly installed at the bottom end of the second connecting rod 220, and bristles 225 are installed at the bottom height of the brush plate 224. A filter plate 226 is fixedly installed at the rear side of the top of the conveyor 101. The bristles 225 slide in the filter plate 226. The sliding of the ball 219 allows the brush plate 224 to move up and down. The bristles 225 on the brush plate 224 can spread the sprayed glue on the circuit board 104. At the same time, the movement of the brush plate 224 allows the bristles 225 to continuously slide on the filter plate 226, squeezing the glue attached to the bristles 225 back onto the circuit board 104, preventing the bristles 225 from bringing out too much glue, and also preventing too much glue from solidifying on the bristles 225 and affecting the use.

[0021] The nozzle assembly 300 includes a plurality of multi-section nozzles 301 fixedly mounted on the bottom of the glue storage tray 212, a plurality of servo motors 302 fixedly mounted on the top of the glue storage tray 212, a rotating rod 303 fixedly mounted on the output end of the servo motor 302, a first ball 304, a second ball 305 and a third ball 306 fixedly mounted on the bottom end of the rotating rod 303, the multi-section nozzle 301 is divided into three layers, the upper, middle and lower layers, and the diameter of each layer decreases successively, the lengths of the first ball 304, the second ball 305 and the third ball 306 correspond to the diameter of each section of the multi-section nozzle 301, and during the spraying process, the rotating rod is driven by the servo motor 302 to rotate. 303 drives the first ball 304, the second ball 305 and the third ball 306 to rotate respectively. The first ball 304, the second ball 305 and the third ball 306 rotate on the circular inner wall of the multi-section nozzle 301. The first ball 304 is provided with two sets of tilting heads, and the second ball 305 and the third ball 306 are provided with one set of tilting heads. Since the air can easily enter the nozzle to solidify the glue, the balls can not only effectively scrape the glue attached to the inner wall for reuse and prevent solidification, but also slowly stir the glue entering the multi-section nozzle 301, so that the internal glue is more substantial, the generation of bubbles is reduced, and the quality of spraying is improved.

[0022] The circuit board 104 is transported by the conveyor 101, and the control console 105 transports the glue to the glue storage tray 212. Under the drive of the servo motor 202, its output end drives the first chain tray 203 to rotate forward and reverse. The first chain tray 203 cooperates with the chain 205 and the second chain tray 204 to make the third chain tray 206 move left and right in the bottom plate 201. The movement of the third chain tray 206 makes the slider 207 drive the first connecting rod 210 to slide on the slide rod 209. The sliding of the first connecting rod 210 drives the movement of the glue storage tray 212, so that it sprays glue from the multi-section nozzle 301 while performing reciprocating left and right motion, so that when the circuit board 104 is transported backward, the glue can be sprayed on the circuit board 104 by sliding left and right, achieving a uniform spraying effect.

[0023] When the circuit board 104 continues to be transported backward, the movement of the plastic storage tray 212 drives the rack 213 to drive the gear 215, so that the hollow tube 214 rotates, and the ball 219 in the hollow tube 214 will first slide in the first slide groove 221. When the rack 213 no longer drives the gear 215, the ball 219 will slide back to the top in the vertical slide groove 223 due to the elastic force of the spring 217. When the rack 213 drives the gear 215 in the reverse direction, the ball 219 will slide in the second slide groove 222. The brush plate 224 slides and then returns to the top through the vertical slide groove 223. The sliding of the ball 219 causes the brush plate 224 to move up and down. The bristles 225 on the brush plate 224 can spread the sprayed glue evenly on the circuit board 104. At the same time, the movement of the brush plate 224 causes the bristles 225 to continuously slide on the filter plate 226, squeezing the glue attached to the bristles 225 back onto the circuit board 104, preventing the bristles 225 from bringing out too much glue and preventing too much glue from solidifying on the bristles 225 and affecting use.

[0024] During the spraying process, the servo motor 302 drives the rotating rod 303 to rotate the first ball 304, the second ball 305 and the third ball 306 respectively. The first ball 304, the second ball 305 and the third ball 306 rotate on the circular inner wall of the multi-section nozzle 301. Since the air can easily enter the nozzle to solidify the glue, the balls can not only effectively scrape the glue attached to the inner wall for reuse and prevent solidification, but also slowly stir the glue entering the multi-section nozzle 301, so that the internal glue is more substantial, the generation of bubbles is reduced, and the quality of spraying is improved.
