Detailed implementation manners

[0018] The technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figure 1 and Figure 2 As shown, a surface spraying device for electronic hardware includes a placement plate 1 and a spraying mechanism 2. First baffles 3 and second baffles 4 are fixedly arranged at both ends of the placement plate 1 respectively. Four legs 29 are fixedly arranged at one end of the placement plate 1 away from the first baffle 3 and the second baffle 4. A mounting plate 5 is fixedly connected between the first baffle 3 and the second baffle 4. The spraying mechanism 2 is slidably arranged on the mounting plate 5. A scraping component 6 for scraping the paint adhered to the baffle is arranged on the first baffle 3. The scraping component 6 includes a first motor 7, a swing rod 8, a cross bar 9 and a first scraping rod 10. The swing rod 8 is fixedly installed on the output shaft of the first motor 7. The cross bar 9 is slidably arranged on the side of the first baffle 3 away from the placement plate 1. One end of the swing rod 8 away from the first motor 7 abuts against the cross bar 9. Then when the swing rod 8 is controlled by the first motor 7 to swing downward, the cross bar 9 loses the supporting force of the swing rod 8 and also slides downward due to gravity. When the swing rod 8 is controlled by the first motor 7 to swing upward, the swing rod 8 supports the cross bar 9 to slide upward on the first baffle 3, realizing the reciprocating scraping of the first baffle 3. A first connecting rod 11 is fixedly connected between the cross bar 9 and the first scraping rod 10. The first scraping rod 10 abuts against one end of the first baffle 3 close to the placement plate 1.

[0020] A cross plate 12 is fixedly installed on the first baffle 3, a first motor 7 is fixedly arranged on the cross plate 12, both ends of a first scraping rod 10 are fixedly connected with second connecting rods 13, one end of the second connecting rod 13 far from the first scraping rod 10 is fixedly connected with a second scraping rod 14, brush hairs are arranged on the first scraping rod 10 and the second scraping rod 14. When the first scraping rod 10 and the second scraping rod 14 slide downwards, the paint is brushed down into the receiving box 21 by the brush hairs. When the first scraping rod 10 and the second scraping rod 14 slide upwards, the paint flows out into the receiving box 21 through the gaps between the brush hairs. The second scraping rod 14 abuts against the side of the second baffle 4 close to the first baffle 3, and the second scraping rod 14 is fixedly connected with the first scraping rod 10 through the second connecting rod 13. Then when the first scraping rod 10 reciprocates up and down to scrape the paint on the first baffle 3, the second scraping rod 14 also scrapes the paint adhered to the second baffle 4, so that the paint is timely scraped into the diversion groove 19 and then flows into the receiving box 21 through the diversion groove 19.

[0021] The spraying mechanism 2 includes a slider 15, a connecting pipe 16, a nozzle 17 and a first vertical plate 18. The first vertical plate 18 is used to prevent the paint sprayed from the nozzle 17 from splashing back and forth. After a period of use, the nozzle 17 and the first vertical plate 18 can be removed and cleaned or processed together. A second motor 27 is fixedly arranged on the mounting plate 5, a lead screw 28 is coaxially and fixedly arranged on the output shaft of the second motor 27, the slider 15 is in threaded connection with the lead screw 28, the slider 15 is slidably arranged on the mounting plate 5, the connecting pipe 16 penetrates through the slider 15, the nozzle 17 is fixedly arranged at one end of the connecting pipe 16 close to the placing plate 1, the other end of the connecting pipe 16 far from the nozzle 17 is connected with an external paint tank, and two first vertical plates 18 are arranged and symmetrically fixedly arranged on both sides of the nozzle 17.

[0022] Diversion grooves 19 are formed on both sides of the placing plate 1 close to the first baffle 3 and the second baffle 4. Second vertical plates 20 are symmetrically and fixedly arranged on the side of the placing plate 1 far from the first baffle 3 and the second baffle 4. A receiving box 21 for receiving the scraped paint is slidably arranged on each of the two second vertical plates 20, and the receiving box 21 is arranged on the side of the diversion groove 19 far from the placing plate 1.

[0023] A spring 22 is fixedly connected to the bottom of the receiving box 21, one end of the spring 22 far from the receiving box 21 is fixedly connected with a bottom plate 23, a vertical rod 24 is fixedly installed on the bottom plate 23, a rotating rod 25 is rotatably arranged on the vertical rod 24, one end of the rotating rod 25 abuts against the bottom of the receiving box 21, and prompting bells 26 are symmetrically and fixedly arranged on the mounting plate 5. The other end of the rotating rod 25 far from the receiving box 21 cooperates with the prompting bell 26. When the load-bearing of the receiving box 21 reaches the maximum, the rotating rod 25 on the side close to the receiving box 21 rotates downwards to the maximum angle, and the rotating rod 25 on the other side rotates upwards to contact the prompting bell 26, so that the prompting bell 26 makes a sound to prompt the staff to timely process the receiving box 21.

[0024] When the utility model is in use, the hardware parts to be subjected to surface spraying treatment are placed between the two vertical plates 18 on the placing plate 1. The second motor 27 is started, and the second motor 27 controls the rotation of the lead screw 28. The slider 15 threadedly connected to the lead screw 28 drives the nozzle 17 to reciprocate. The paint in the nozzle 17 is evenly coated on the surface of the hardware parts. During the spraying process, a part of the paint splashes onto the first baffle 3 and the second baffle 4. The first motor 7 is started, and the first motor 7 controls the swing rod 8 to rotate. Then the cross bar 9 in contact with the swing rod 8 slides relative to the first baffle 3. The cross bar 9 drives the connected first scraping rod 10 and the second scraping rod 14 to slide down. The scraping rods slide down in time to scrape off the paint adhered to the first baffle 3 and the second baffle 4, avoiding the situation that the paint cannot be scraped off in time and dries on the first baffle 3 and the second baffle 4. The paint scraped off by the first scraping rod 10 and the second scraping rod 14 flows into the receiving box 21 through the diversion groove 19. When the paint in the receiving box 21 reaches the maximum capacity of the receiving box 21, the spring 22 installed at the bottom of the receiving box 21 is compressed. The side of the rotating rod 25 close to the receiving box 21 swings downward, and the other side swings upward to contact the reminder bell 26, causing the reminder bell 26 to emit a sound to remind the staff to replace or pour the receiving box 21 in time.
