Description

Technical Field

[0001] The utility model belongs to the technical field of dust collecting machines, in particular to a dust collecting machine for PCB. Background Art

[0002] PCB dust collector is also called board cleaning machine. The working principle is: use the dust-adhesive rubber roller to absorb the dust and debris on the surface of the PCB to be cleaned, transfer the dust and debris to the dust-adhesive roller, and achieve the purpose of cleaning the surface of the PCB.

[0003] The dust on the sticky roller set in the PCB dust sticking machine is also cleaned by the sticky roller. The sticky roller and the sticky roller contact each other, thereby taking away the dust on the sticky roller, so that the sticky roller can maintain a high viscosity state to clean the dust. Then, as more dust accumulates on the sticky roller, its viscosity will decrease, and the adhesion to the dust on the sticky roller will also decrease. For this reason, we propose a dust sticking machine for PCB to solve the above problems. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example: Figure 1 As shown, a dust collecting machine for PCB includes a dust collecting machine body 10, a dust collecting assembly 20 arranged in the dust collecting machine body 10, and a transport assembly 30 for transporting the PCB board. When in use, the PCB board is placed on the transport assembly 30, and the transport assembly 30 is started to drive the PCB board to pass through the dust collecting assembly 20, so as to complete the dust cleaning on the surface of the PCB board;

[0026] The specific cleaning process is as follows: Figure 2 As shown, the dust sticking assembly 20 includes two groups of parallelly arranged connecting plates 201, wherein the outer side wall of one group of connecting plates 201 is also fixedly connected with a handle 202, and the two groups of connecting plates 201 are fixedly connected by a bracket 205, and a dust sticking roller 203 is also rotatably arranged between the two connecting plates 201, and the dust sticking roller 203 can be a material with a certain viscosity such as silica gel. When the PCB board is placed on the transport assembly 30, its top and the dust sticking roller 203 are in contact with each other. During transportation, the PCB board moves past the dust sticking roller 203 to drive it to rotate, and the dust sticking roller 203 adheres and removes the dust on the PCB board through its sticky characteristics;

[0027] As shown in 2-5, in order to keep the sticky roller 203 sticky and adhere the dust on the PCB board, a sticky roller is also provided corresponding to the sticky roller 203, wherein the sticky roller includes a first sticky roller 208 and a second sticky roller 209, and the first sticky roller 208 and the sticky roller 203 are in contact with each other. When the sticky roller 203 rotates, the dust attached to the surface of the sticky roller 203 is adhered and sucked away by the first sticky roller 208;

[0028] In order to ensure that the first sticky roller 208 is clean, the first sticky roller 208 is also in contact with the second sticky roller 209, wherein, as shown in FIG. Figure 3 and Figure 5 As shown, a first gear 211 is fixedly sleeved on the rotating shaft of the first dust-sticking roller 208, and the first gear 211 is also meshed with a second gear 212. When the first gear 211 and the second gear 212 rotate, the directions are opposite. Figure 5 As shown, the rotation direction of the first sticky roller 208 is a', and the rotation direction of the second sticky roller 209 is a, and the rotation directions of a and a' are opposite. A shell 204 is also provided on the outer side of the first sticky roller 208 and the second sticky roller 209, wherein Figure 5 As shown, the contact point between the housing 204 and the first sticky roller 208 and the second sticky roller 209 is in an arc shape. When the first sticky roller 208 and the second sticky roller 209 rotate along directions a and a' respectively, the dust on the first sticky roller 208 is firstly transmitted to the second sticky roller 209. According to the rotation direction of the two groups of rollers, it can be seen that the dust is scraped off by the contact area between the housing 204 and the rollers and remains in the housing 204, so that the first sticky roller 208 is kept clean and the dust on the sticky roller 203 can be continuously cleaned;

[0029] Among them, Figure 3 As shown, a fixing plate 206 is fixedly installed on the inner wall of the connecting plate 201, and a slider 207 is slidably connected to the inner wall of the fixing plate 206. A mounting seat 213 is fixedly arranged on the slider 207, and the dust-sticking roller is rotatably arranged on the mounting seat 213. A plate body is also formed on the side wall of the fixing plate 206, and the plate body is provided with a threaded hole, in which a fixing bolt 210 is threadedly connected. A corresponding threaded hole is also provided in the slider 207, and the fixing bolt 210 is screwed into the threaded hole of the slider 207, so that the dust-sticking roller can be fixed and keep in contact with the dust-sticking roller 203. After using it for a period of time, the dust in the shell 204 can be cleaned, the fixing bolt 210 is screwed out, and the slider 207 is taken down from the fixing plate 206. Pistons 214 are also embedded at the front and rear ends of the shell 204, and the piston 214 is pulled out to pour out the dust in the shell 204.
