[0046] As shown in Figures 1 to 6 The steel mesh cleaning device provided by the present embodiment comprises a frame body 1, a spraying pipe 2, and a wiping assembly 3. The spraying pipe 2 is installed on the frame body 1, and the spraying pipe 2 is provided with liquid spraying micro-holes. The cleaning solvent is uniformly sprayed on the anti-static cleaning paper on the wiping assembly 3 under the action of the pump body such as a diaphragm pump.

[0047] The wiping assembly 3 comprises a first sliding frame 301, a paper releasing device 302, a paper rolling device 303, a first telescopic device 304, a lifting platform 305, a first top bar 306, and a second top bar 307. The paper releasing device 302 can release the cleaning paper for wiping the steel mesh body, and the paper rolling device 303 can roll up the cleaned cleaning paper. The first telescopic device 304 can drive the lifting platform 305 to ascend or descend so as to make the lifting platform 305 close to or away from the steel mesh body. The first top bar 306 and the second top bar 307 are used for lifting the cleaning paper, so that the cleaning paper abuts against the steel mesh body, and the wiping and cleaning of the steel mesh body are realized.

[0048] The frame body 1 has a cleaning channel, the spraying pipe 2 and the wiping assembly 3 are sequentially arranged along the cleaning channel, and the steel mesh body is sequentially cleaned by passing through the spraying pipe 2 and the wiping assembly 3 into the cleaning channel. The first sliding frame 301 is slidably arranged on the frame body 1, and the first sliding frame 301 is slidably arranged in the cleaning channel in the front-rear direction. The first sliding frame 301 can move back and forth to realize repeated wiping of the steel mesh body by the wiping assembly 3. The paper dispenser 302, the paper winder 303 and the first telescopic device 304 are all mounted on the first sliding frame 301, and the paper dispenser 302, the paper winder 303 and the first telescopic device 304 slide with the first sliding frame 301. The output end of the first telescopic device 304 is in transmission connection with the lifting platform 305, the paper dispenser 302, the lifting platform 305 and the paper winder 303 are sequentially and spacedly arranged along the sliding direction of the first sliding frame 301, the first top strip 306 and the second top strip 307 are spacedly arranged on the lifting platform 305 along the sliding direction of the first sliding frame 301, and the lifting platform 305 is provided with an adsorption channel 326 located between the first top strip 306 and the second top strip 307. The adsorption channel 326 can be connected with a vacuum pump to generate negative pressure in the adsorption channel 326. When the steel mesh cleaning device cleans the steel mesh body, the spraying pipe 2 sprays cleaning solvent, the wiping assembly 3 slides, the paper dispenser 302 releases cleaning paper, the cleaning paper passes through the lifting platform 305 and is then wound by the paper winder 303. The first telescopic device 304 can be a pneumatic cylinder, a hydraulic cylinder or an electric telescopic rod, etc. The first telescopic device 304 drives the first top strip 306 and the second top strip 307 on the lifting platform 305 to rise, so that the cleaning paper can abut against the steel mesh body, and the first sliding frame 301 is driven to slide, so that the cleaning paper can wipe the steel mesh body. In the wiping process, the adsorption channel 326 generates negative pressure to adsorb the tin paste falling on the steel mesh body, thereby improving the cleaning efficiency and effect of the steel mesh body. The adsorbed tin paste will fall on the cleaning paper and will not enter the adsorption channel 326 to cause blockage.

[0049] In one embodiment, the steel mesh cleaning device further comprises a camera assembly 4 slidably arranged on the frame body 1.

[0056] Optionally, the wiping assembly 3 further comprises a pipe joint 308 and a suction pipe 309 for connecting an external pump body. The suction pipe 309 is a flexible pipe, and the suction pipe 309 is connected with the pipe joint 308. The suction channel 326 comprises, from top to bottom, a suction groove 327, a plurality of communication holes 328, and a pipe groove 329. The communication holes 328 are arranged at intervals. The pipe groove 329 is in communication with the suction pipe 309 through the pipe joint 308, and the suction pipe 309 is used to connect an external vacuum pump. The lower surface of the lifting platform 305 is provided with the pipe groove 329 which has a trapezoidal cross section. The trapezoidal shape of the pipe groove 329 can increase the volume and improve the adsorption force. The lifting platform 305 is provided with a plurality of communication holes 328 arranged at intervals in the middle, and the upper surface of the lifting platform 305 is provided with the suction groove 327. When the vacuum pump is started, the suction groove 327 forms a negative pressure to adsorb and wipe off the solder paste.

[0058] When the wiping assembly 3 is started, a low-pressure area is formed on the cleaning paper between the first top strip 306 and the second top strip 307. While the cleaning paper wipes the steel mesh body, it generates negative pressure to adsorb the residual solder paste on the steel mesh body, effectively enhancing the solder paste cleaning effect. The cleaning paper can also play a filtering role to prevent the residual solder paste from entering the pipeline connected to the vacuum pump through the suction channel 326 and polluting or even blocking the pipeline and the vacuum pump.

[0059] Optionally, the steel mesh cleaning device can meet the cleaning needs of steel mesh bodies of different sizes by replacing the spray pipe 2 of different lengths, the cleaning paper roll of different lengths, and the first top strip 306 and the second top strip 307 of different lengths.

[0060] In addition, the steel mesh cleaning device can be converted into a paperless cleaning device by replacing the lifting platform 305, the first top strip 306 and the second top strip 307 with a scraping strip mounting plate and a wiping scraping strip, respectively, while the remaining structure remains unchanged. Meanwhile, different lengths of wiping scraping strips can be switched to meet the cleaning requirements of steel meshes of different sizes.

[0066] The paper roll counting assembly 7 comprises a support frame 701 mounted on the first sliding frame 301, a swing frame 702 rotatably mounted on the support frame 701, a first photoelectric sensor 703 mounted on the swing frame 702, and a follower wheel 705 and a counting disc 706 rotatably mounted on the swing frame 702. The follower wheel 705 is drivingly connected to and synchronously rotates with the counting disc 706 through a connecting shaft 707. The first photoelectric sensor 703 has a first detection channel 708. The counting disc 706 is provided with a plurality of baffles 714 which are spaced apart along the circumferential direction of the rotation axis of the counting disc 706. Adjacent baffles 714 form a light beam channel 715. The first detection channel 708 is located on the rotation path of the baffles 714 and the light beam channel 715. During the rotation of the counting disc 706, the baffles 714 and the light beam channel 715 realize real-time switching of the communication and interruption of the photoelectric signal on the first photoelectric sensor 703, and the feedback acts on the motor 315 to accurately control the unwinding amount, so as to realize accurate control of the consumption of the cleaning paper.

[0067] When the baffle 714 passes through the first detection channel 708, the laser emitted by the first photoelectric sensor 703 is blocked. When the light beam channel 715 passes through the first detection channel 708, the laser emitted by the first photoelectric sensor 703 can propagate in the first detection channel 708. According to the number and time of the blocked light beams, the length of the released cleaning paper can be calculated, the accurate control of the paper consumption is realized, the invalid loss of the cleaning paper is reduced, the remaining amount of the cleaning paper is synchronously evaluated, and the operator is timely warned to replace the cleaning paper roll.

[0068] Optionally, the paper roll counting assembly 7 further comprises a spring hinge 710. The swing frame 702 is rotatably mounted on the support frame 701 through the spring hinge 710. The spring hinge 710 is used to apply a spring force to the swing frame 702 so that the outer circumferential side of the follower wheel 705 abuts against the paper surface of the cleaning paper. By using the spring hinge 710, it can be ensured that the outer circumferential side of the follower wheel 705 abuts against the paper surface of the cleaning paper. The outer circumferential side of the follower wheel 705 is tangent to the cleaning paper. When the cleaning paper wipes the steel mesh body, it can drive the follower wheel 705 to rotate, thereby driving the counting disc 706 to rotate.

[0069] In other embodiments, the outer circumferential side of the follower wheel 705 can also abut against the cleaning paper under the action of gravity.

[0070] Further, the paper roll counting assembly 7 further comprises a second photoelectric sensor 704 installed on the support frame 701. The second photoelectric sensor 704 has a second detection channel 709, the swing frame 702 has a shielding part 711, and the second detection channel 709 is located on the moving path of the shielding part 711. When the cleaning paper is used up, the outer circumferential side of the follow-up wheel 705 is not blocked by the cleaning paper, the swing frame 702 continues to rotate under the action of the spring hinge 710, so that the shielding part 711 is separated from or enters the second detection channel 709, and the second photoelectric sensor 704 controls the paper roll counting assembly 7 to stop working according to the change of the propagation of the light beam in the second detection channel 709, and timely warns the operator to replace the cleaning paper roll.

[0071] Optionally, the paper roll counting assembly 7 further comprises a first locking piece 712 and a second locking piece 713. The support frame 701 and the swing frame 702 are both sheet metal, the thickness of the support frame 701 and the swing frame 702 is small, the first photoelectric sensor 703 is installed on the swing frame 702 through the first locking piece 712, and the second photoelectric sensor 704 is installed on the support frame 701 through the second locking piece 713. The first locking piece 712 can increase the local thickness of the swing frame 702, and the second locking piece 713 can increase the local thickness of the support frame 701, so as to facilitate the installation and locking of the first photoelectric sensor 703 and the second photoelectric sensor 704.

[0072] The steel mesh cleaning device is located in front of the steel mesh body before starting the cleaning work of the steel mesh body, and has no contact with the steel mesh body, so as to prepare for the cleaning of the steel mesh body. The paper dispenser 302 and the paper roll device 303 control the release and recovery of the dirty paper, respectively, and the first top bar 306 and the second top bar 307 arranged between the paper dispenser 302 and the paper roll device 303 are stretched upward under the action of the first telescopic device 304, so that the cleaning paper above the first top bar 306 and the second top bar 307 is tightly attached to the steel mesh body above. The release and winding speed of the paper dispenser 302 and the paper roll device 303 can effectively tension the anti-static cleaning paper. The diaphragm pump controls the cleaning solvent to be uniformly sprayed on the cleaning paper through the spraying pipe 2, so as to fully wet the cleaning paper and facilitate the subsequent cleaning work.

[0073] The camera assembly 4 slides towards the wiping assembly 3, when the limit sensor of the camera assembly 4 receives an induction signal, the second telescopic device 312 drives the positioning pin 313 to move upward and insert into the positioning hole of the positioning seat 402, realizing linkage of the camera assembly 4 and the wiping assembly 3, at this time, under the driving of the camera assembly 4, the wiping assembly 3 is cleaned with the steel mesh body. By adjusting the installation height of the lifting platform 305 of the height adjusting screw, the contact degree of the cleaning paper lifted by the first top bar 306 and the second top bar 307 with the back surface of the steel mesh body can be adjusted, so as to avoid damage of the cleaning paper caused by excessive contact of the cleaning paper with the steel mesh body or insufficient cleaning degree caused by insufficient contact of the cleaning paper with the steel mesh body. The first top bar 306 and the second top bar 307 are slightly convex on the upper surface of the lifting platform 305, and the adsorption channel 326 opened in the middle of the lifting platform 305 is lower than the upper surface of the lifting platform 305, and there is a certain height difference between the two. When the vacuum pump is started, the cleaning paper between the first top bar 306 and the second top bar 307 forms a low-pressure area under the action of negative pressure, and the residual solder paste on the steel mesh body is sucked, and the ideal cleaning effect is ensured by cooperating with the wiping action of the cleaning paper.

[0074] In the process of cleaning the steel mesh body by the cleaning paper, under the action of the spring tension of the spring hinge 710, the follow-up wheel 705 is always in contact with the cleaning paper when the paper feeder 302 transports the cleaning paper. When the cleaning paper in the paper feeder 302 is exhausted, the follow-up wheel 705 is separated from the cleaning paper, and the second photoelectric sensor 704 is triggered to feed back that the cleaning paper is exhausted and needs to be replaced. When replacing the cleaning paper, the compression elastic member 320 can quickly unload and replace the reel 321 with new cleaning paper or the reel 321 with dirty cleaning paper. The wiping assembly 3 can adjust the rotating speed of the paper feeder 302 combined with the on-off frequency of the signal of the first photoelectric sensor 703, and the best configuration parameters are obtained by comparing the cleaning effect and the dirt degree of the cleaning paper corresponding to the paper feeders 302 with different rotating speeds, so that the consumption of the cleaning paper is controllable. At the same time, the length of the cleaning paper roll of each reel 321 is similar, and the length of the unwound cleaning paper each time is controllable, so that the remaining amount of the cleaning paper and the cleaning frequency of the steel mesh can be roughly evaluated.
