[0018] In order to make the technical problems, technical solutions, and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention. Before describing the present invention in detail, it should be noted that similar components are represented by the same reference numerals in the following description.

[0019] See also Figure 1-4As shown, as a preferred embodiment of the present invention, a diversion and collection device 10 is disclosed, which is applied to sprayer equipment and installed under the exhaust pipe 110 to collect condensed droplets of exhaust gas. It includes: a diversion cover 120, two collection tanks 130 and an exhaust cover 140. By the way, the diversion and collection device 10 is often set on a machine in a factory that generates exhaust gas. Through this application, the gaseous or misty exhaust gas can be condensed and collected into liquid droplets, preventing the gaseous or misty exhaust gas from affecting the spraying efficiency of the PCBA due to the inability to divert and collect the droplets in time, resulting in poor spraying, and further affecting the quality of the PCBA board. It should be noted that the PCBA board is a product sprayed with flux. In one embodiment of the present invention, the exhaust gas is a flux. For example, when a PCBA slides directly above the nozzle at the front end of the corresponding sprayer, flux is sprayed onto the PCBA through the nozzle, causing the flux to be sprayed onto the PCBA and atomized. The flux vapor or mist on the PCBA is then condensed and collected into liquid droplets through the guide and collection device 10. The operating principle of spraying PCBAs with a sprayer is well known in the art and will not be elaborated on here.

[0020] In an embodiment of the present application, the top of the flow guide cover 120 is provided in an inverted V shape by two top plates 121, and the bottom of each of the two top plates 121 is connected to a side plate 122, the side plate 122 is provided with a plurality of exhaust holes 123, the exhaust holes 123 are used to exhaust the flux, the flux sprayed upward through the nozzle is condensed into droplets when it meets the inner wall of the top of the flow guide cover 120, and the droplets slide down the top plate 121 to the exhaust holes 123 of the side plate 122 under the action of gravity. Secondly, the collection groove 130 is arranged close to the two ends of the flow guide cover 120, or in other words, a collection groove 130 is arranged below each side plate 122 to collect the condensed droplets that slide down the top plate 121 of the flow guide cover 120 to the side plate 122. Finally, the exhaust hood 140 is arranged on the flow guide cover 120 and the collection groove 130, and the top end of the exhaust hood 140 is provided with an exhaust port 141, and the exhaust port 141 is used in combination with the exhaust duct 110 to facilitate the flux to rise to the top of the exhaust hood 140 and the flow guide cover 120 when it volatilizes upward through the exhaust holes 123 under the action of the wind of the exhaust duct 110. In detail, the exhaust hood 140 is arranged above the production equipment for volatilizing the flux, wherein the production equipment can be a spraying machine for spraying the flux, but is not limited thereto. The flux is sprayed upward through the nozzle below the flow guide and collection device 10, the atomized flux volatilizes or rises upward under the action of the wind of the exhaust duct 110, a part of the atomized flux passes through the exhaust holes 123 and rises to the top of the exhaust hood 140, and the other part of the atomized flux rises to the top of the flow guide cover 120. The atomized flux is condensed into droplets after being cooled by the inner wall of the top of the exhaust hood 140 and the flow guide cover 120, the droplets slowly slide down the top plate 121 of the flow guide cover 120 to the side plate 122 under the action of gravity, and finally drop into the collection groove 130, thereby realizing the flow guide collection of the condensed droplets of the flux. Through the above technical means, the condensed droplets of the flux are collected through the cooperation of the exhaust duct 110, the flow guide cover 120, the collection groove 130, and the exhaust hood 140, the droplets can be collected in time, it is convenient to use, and it does not need too complicated steps, which can effectively avoid the problem that the condensed flux droplets cannot be collected in time, thereby causing product pollution or damage, and effectively improve the efficiency.

[0021] The sprayer further includes at least one bracket 150. The collection trough 130 further includes a base plate 131 mounted on the bracket 150, supporting the collection trough 130. The exhaust hood 140 further includes two vertical plates 144, and the bracket 150 engages with the lower ends of the vertical plates 144 to support the exhaust hood 140. Specifically, the base plate 131 is mounted on the bracket 150, contacting the base plate 131 with the bracket 150, thereby coupling the collection trough 130 to the bracket 150. At this point, the deflector 120 is mounted on the collection trough 130, and the bracket 150 supports the deflector 120 and the collection trough 130. The exhaust hood 140 is coupled to the bracket 150 through contact between the lower ends of the vertical plates 144 and the bracket 150, thereby supporting the exhaust hood 140. It should be noted that the diversion and collection device 10 can be placed at any position on the bracket 150. It is only necessary to ensure that the bracket 150 can carry the diversion and collection device 10, so that the bracket 150 can play a supporting role. No special explanation is given here, but it is not limited to this.

[0022] Furthermore, the top bend angle of the top plate 121 is 60-120 degrees. It should be noted that the bend angle of the top plate 121 is designed to allow the droplets condensed from the exhaust hood 140 to drip onto the surface of the top plate 121 under the action of gravity, and then slide down the top bend angle of the top plate 121 to the side plate 122 connected to the top plate 121. Of course, the droplets condensed from the top of the deflector 120 also slide down the top bend angle of the top plate 121 to the side plate 122 connected to the top plate 121. Through the above operation method, it can be seen that the droplets condensed on the top of the exhaust hood 140 and the deflector 120 will slide down to the surface of the top plate 121. In order to allow the droplets to slide from the top plate 121 to the side plates 122, it is necessary to limit the bend angle of the top plate 121. The bend angle allows the droplets to slide down along the top plate 121. Of course, the bend angle of the top plate 121 can also be determined according to actual needs, but is not limited to this.

[0023] Then, as a preferred embodiment, the exhaust cover 140 further includes a removable shielding plate 142, and the shielding plate 142 is further provided with a handle 143. It should be noted that the exhaust cover 140 is provided with a movable and removable shielding plate 142. When replacing the deflector 120 and the collection tank 130 inside the exhaust cover 140, the shielding plate 142 can be removed to facilitate the placement of the deflector 120 and the collection tank 130 into the exhaust cover 140. Of course, in order to facilitate the removal of the shielding plate 142, a handle 143 can be provided on the shielding plate 142, but the present invention is not limited thereto.

[0024] Furthermore, the exhaust hole 123 is arranged in a fence shape. It should be noted that the exhaust hole 123 is designed to allow the exhaust gas ejected upward through the nozzle to evaporate upward into the air deflector 120. A portion of the atomized exhaust gas passes through the exhaust hole 123 under the action of the wind from the exhaust pipe 110 and rises to the top of the exhaust hood 140. In addition, the exhaust hole 123 is also designed to allow the atomized exhaust gas to condense into droplets through the exhaust hood 140 and the top of the air deflector 120. The droplets slide down from the top plate 121 to the side plate 122 and flow into the collection tank 130 through the exhaust hole 123. Of course, the shape of the exhaust hole 123 can also be determined according to actual needs, as long as it can meet the above-mentioned operations, but it is not limited to this.

[0025] Furthermore, the collection trough 130 is rectangular. It should be noted that the collection trough 130 is intended to collect droplets that slide down from the top plate 121 of the air deflector 120 to the side plates 122. Therefore, the shape of the collection trough 130 is not particularly limited. However, in this embodiment, the collection trough 130 is rectangular to facilitate the collection of droplets condensed from the air deflector 120, but the invention is not limited thereto. Incidentally, the collection trough 130 also needs to ensure that the side plates 122 of the air deflector 120 can be installed on the collection trough 130 to prevent the side plates 122 from being too long and exceeding the size of the collection trough 130, so that some droplets that slide down from the side plates 122 beyond the collection trough 130 cannot be collected by the collection trough 130, thereby causing these droplets to contaminate the product. However, the invention is not limited thereto.

[0026] Furthermore, the air guide cover 120 is made of a rigid material. It should be noted that a stainless steel with a smooth surface and corrosion resistance can be selected to facilitate the atomized exhaust gas to rise through the exhaust hole 123 to the exhaust cover 140 and the top of the air guide cover 120 under the action of the wind force of the exhaust pipe 110, and then slide down and drip. The formed droplets will drip onto the surface of the air guide cover 120 and slide down along the surface of the air guide cover 120 into the collection tank 130.

[0027] It can be seen that when assembling the diversion and collection device 10, the exhaust hood 140 is first placed on the bracket 150, and the baffle 142 is removed from the exhaust hood 140 by the handle 143. The collection tank 130 and the deflector 120 are placed in sequence from one end of the baffle 142 of the exhaust hood 140, and the collection tank 130 is installed directly below the side panel 122 of the deflector 120 to collect the droplets sliding down from the deflector 120. Finally, the baffle 142 is installed on one end of the exhaust hood 140 by the handle 143. Through the above installation process, the exhaust gas sprayed from the PCB board through the nozzle can be condensed into droplets by the diversion and collection device 10, and the sliding or dripping droplets can be diverted and collected.

[0028] In summary, the diversion and collection device 10 of the present invention, through the cooperation of the diversion cover 120 and the collection tank 130, can solve the problem that when the nozzle sprays out exhaust gas, it condenses into droplets through the exhaust cover 140 and the top of the diversion cover 120 and slides down to the diversion cover 120. The collection tank 130 diverts and collects the sliding droplets in time, reducing the contamination of the droplets to the product, improving the quality of the product, and greatly improving the spraying efficiency.

[0029] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
