Description

TECHNICAL FIELD

[0002] In the production process of circuit boards, a brush plate machine is often used to actively remove dust from the bottom of the circuit board in the production process through bristles, and an ion blower is used to blow the surface of the circuit board to prevent static electricity generated by friction from attracting dust. The existing method often uses two transmission belts to cover the two sides of the bottom of the circuit board, and then the transmission belt is used to transmit the circuit board to the cleaning area of the brush plate machine for cleaning work, thereby realizing automatic cleaning. However, this conveying method will cause the transmission belt to be blocked at the part in contact with the bottom of the circuit board, resulting in a blind area, so that the bottom of the circuit board cannot be completely cleaned, and there is still a situation of dust attachment. When a soft brush is used to clean the circuit board, the long-term use of the soft brush will cause it to fall off. When the fallen bristles come into contact with the grooves and welding points on the circuit board, they will be attached to the bottom of the circuit board, so that manual observation is required to determine whether the bristles are attached to each circuit board, thereby increasing the labor cost, and manual observation of the circuit board also causes secondary pollution.

DETAILED DESCRIPTION

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] Example 1: As Figures 1-6 As shown, an intelligent brushing machine capable of active dust removal includes a control box 1, an ion fan 2, and a cleaning component; the ion fan 2 is installed on the upper side of the control box 1; several air outlets 2002 are opened on the lower side of the ion fan 2; the cleaning component is installed inside the control box 1.

[0029] It also includes an adjustment plate 4, a servo motor 101, a conveyor belt 102, an electric slider 105, and a combing assembly; the servo motor 101 is fixedly connected to the upper side of the control box 1; two conveyor belts 102 are rotatably connected to the control box 1 via a roller assembly; the output end of the servo motor 101 drives the conveyor belts 102 to rotate via a transmission rod; the conveyor belts 102 are used to transport the circuit board 3; several slots 2001 are provided on the ion fan 2; an electric slider 105 is slidably connected to each slot 2001; several electric sliders 105 are fixedly connected to the adjustment plate 4, the upper surface of the adjustment plate 4 is in contact with the lower side of the ion fan 2; several air slots 4002 are provided on the adjustment plate 4; the combing assembly is installed inside the control box 1.

[0030] The cleaning assembly includes a brush wheel 103 and a collection box 104. The brush wheel 103 is rotatably connected inside the control box 1. Several soft brushes are fixed on the brush wheel 103 in a ring arrangement. The control box 1 drives the brush wheel 103 to rotate via an external electric motor. Two collection boxes 104 are fixed inside the control box 1. The two collection boxes 104 are located on the left and right sides of the brush wheel 103, respectively. The collection box 104 located on the right side of the brush wheel 103 is provided with comb teeth.

[0031] The combing assembly includes a connecting plate 106, a comb plate 107, and a rubbing plate 108; the connecting plate 106 is fixedly connected to the front side of the adjusting plate 4; the comb plate 107 is fixedly connected inside the control box 1; the rubbing plate 108 is slidably connected to the upper left side of the connecting plate 106; the rubbing plate 108 is attached to the upper side of the comb plate 107.

[0032] Each conveyor belt 102 is equipped with several clips made of elastic rubber to prevent the circuit boards 3 from colliding with each other during transmission.

[0033] It also includes a first card plate 109 and a second card plate 110; the first card plate 109 is fixedly connected to the control box 1 by a spring telescopic rod; the first card plate 109 has a plurality of first card slots 10901; the second card plate 110 is fixedly connected to the control box 1; the second card plate 110 has a plurality of second card slots 11001; the first card plate 109 and the second card plate 110 are in contact.

[0034] Several rotating parts 4001 are provided on the inner side of the adjusting plate 4.

[0035] The comb plate 107 and the rubbing plate 108 are both arranged to be gradually inclined downward to the left.

[0036] The ion fan 2 is located directly above the adjusting plate 4, and the ion fan 2 is close to the circuit board 3, which can remove the static electricity of the circuit board 3 and provide a downward pressure for the circuit board 3, thereby improving the stability of the circuit board 3 during transportation.

[0037] The transmission belt 102 is provided with a plurality of rubber protrusions, which can reduce the contact area between the transmission belt 102 and the circuit board 3, and facilitate the sliding of the circuit board 3 on the transmission belt 102.

[0038] Before cleaning the bottom of the circuit board 3, the circuit board 3 is placed on the transmission belt 102 by an external conveying device or manually, so that the circuit board 3 is placed between the adjacent two clamping strips corresponding to the transmission belt 102, thereby avoiding collision between the adjacent two circuit boards 3 during transportation. From front to back, the servo motor 101 is started to rotate clockwise, thereby making the transmission belt 102 carry the circuit board 3 to move to the right. When the circuit board 3 moves above the brush wheel 103, the external electric motor rotates clockwise, thereby driving the brush wheel 103 to rotate clockwise. The dust remaining on the lower side of the circuit board 3 is brushed off by the brush wheel 103. The dust remaining on the bristles is cleaned by the comb teeth on the collection box 104 on the right side of the brush wheel 103. In this process, the clamping strips on the transmission belt 102 limit the collision between the adjacent two circuit boards 3, thereby realizing continuous cleaning of the circuit board 3. The circuit board 3 does not need to be cleaned by blocking and intercepting the circuit board 3. When the brush wheel 103 cleans the dust on the circuit board 3, the airflow blown out by the ion air blower 2 is blown out from the air slot 4002 through the air outlet 2002, thereby acting on the cleaning area of the brush wheel 103. The static electricity on the circuit board 3 and the brush wheel 103 is eliminated, preventing the dust from being adsorbed on the brush wheel 103 and the circuit board 3 due to static electricity. Finally, the circuit board 3 is transmitted from the right side of the transmission belt 102, and is taken off by a manual or external mechanical hand transfer device and transferred to the subsequent step. In this way, the circuit board 3 is cleaned in a cycle. However, in this process, considering that when the transmission belt 102 is used to convey the circuit board 3, the area where the circuit board 3 contacts the transmission belt 102 cannot be cleaned by the brush wheel 103, resulting in a blind area in the cleaning of the circuit board 3. In order to avoid this phenomenon, the two transmission belts 102 are located under the cage of the adjusting plate 4, and the cleaning range of the brush wheel 103 is greater than the space occupied by the two transmission belts 102. When multiple circuit boards 3 enter the lower side of the adjusting plate 4, the transmission of the circuit board 3 by the transmission belt 102 is stopped. Then, the electric sliding block 105 is started to slide back and forth in the sliding groove 2001, thereby driving the adjusting plate 4 to move forward and backward. When the adjusting plate 4 moves forward, the side edge of the rear side of the circuit board 3 is located at the middle position of the rear transmission belt 102, so that the front side and the rear side of the circuit board 3 are exposed by half. At this time, the exposed area of the circuit board 3 is cleaned by the bristles. Similarly, when the circuit board 3 moves backward, the side edge of the front side of the circuit board 3 is located at the middle of the front transmission belt 102, thereby exposing the other half of the front side and the rear side of the circuit board 3 which contacts the transmission belt 102, and then cleaning the bottom of the circuit board 3 by the brush wheel 103, thereby avoiding incomplete cleaning of the bottom of the circuit board 3 and improving the cleaning effect of the device on the circuit board 3.

[0039] It is also considered that the rubber convex strip arranged on the transmission belt 102 contacts the lower side of the circuit board 3, thereby reducing the contact area between the circuit board 3 and the transmission belt 102, reducing the friction surface, facilitating the movement of the circuit board 3 pushed by the adjusting plate 4, and at the same time, the ion fan 2 is placed directly above the adjusting plate 4, and the air outlet of the ion fan 2 is close to the surface of the circuit board 3, so that the airflow blown by the ion fan 2 eliminates static electricity, and at the same time, the airflow passes through the air groove 4002 and acts on the surface of the circuit board 3, and also provides a downward pressure on the circuit board 3, ensuring the normal transportation and cleaning of the circuit board 3.

[0040] It is also considered that since the circuit board 3 is sensitive and easy to be damaged, and the side edges of the circuit board 3 are in an unprotected state during cleaning, the circuit board 3 gradually moves to the right under the action of the transmission belt 102, and at the same time, the circuit board 3 moves forward and backward under the action of the adjusting plate 4, which will cause the circuit board 3 to move forward and backward during the movement to the right, so that the side edges of the circuit board 3 rub against each other at the contact position with the adjusting plate 4. At this time, the rotating part 4001 contacts the circuit board 3, and the rotating part 4001 rotates with the circuit board 3 to reduce the friction on the side edges of the circuit board 3, and ensure the normal cleaning work of the circuit board 3.

[0041] It is also considered that, in order to reduce the damage of the brush wheel 103 to the circuit board 3, the circuit board 3 is cleaned by the soft brush, and after long-term use, the soft brush on the brush wheel 103 is easy to fall off, and at the same time, due to the existence of grooves and welding points on the lower side of the circuit board 3, the bristles are easy to hook on the circuit board 3 when they contact the grooves and welding points, which will cause the circuit board 3 to be cleaned, and the subsequent manual observation of whether there is bristle residue on the bottom of each circuit board 3 will increase the labor cost, and manual holding of the circuit board 3 will also have the risk of secondary pollution. In order to avoid this phenomenon, before the brush wheel 103 contacts the circuit board 3, the bristles on the brush wheel 103 first pass through the comb plate 107, and the bristles are first combed by the comb plate 107, so that the bristles on the brush wheel 103 are combed off in advance. At the same time, when the bristles have not completely passed through the comb plate 107, the bristles are in a state of being squeezed and bent by the comb plate 107, and when the bristles completely pass through the comb plate 107, the bristles rebound to the initial state, thereby generating a certain gap between the bristles that have not completely passed through the comb plate 107 and the bristles that have completely passed through the comb plate 107. At the same time, when the circuit board 3 passes through the air slot 4002, the combed and fallen bristles are blown away from the brush wheel 103 by the airflow blown by the ion fan 2, improving the cleaning effect of the easy-to-fall bristles. And the comb plate 107 and the rubbing plate 108 are both set to gradually incline to the left, and when the airflow blows to the brush wheel 103 to clean the bristles, the airflow is guided by the comb plate 107 and the rubbing plate 108 to blow to the left side of the brush wheel 103, so that the bristles are collected into the collection box 104. When the soft bristles on the brush wheel 103 are pre-combed, the soft bristles on the brush wheel 103 are used to clean the circuit board 3, thereby effectively reducing the phenomenon that the aged and fallen bristles are hooked on the circuit board 3. Further, when the adjusting plate 4 moves forward and backward, the adjusting plate 4 also drives the connecting plate 106 to move forward and backward, so that the connecting plate 106 drives the rubbing plate 108 to move forward and backward, and the rubbing plate 108 moves forward and backward on the comb plate 107. By combing and rubbing the bristles with the comb plate 107 and the rubbing plate 108, the bristles are more likely to fall off the brush wheel 103, improving the cleaning effect of the easy-to-fall bristles and further reducing the phenomenon of bristles being hooked on the circuit board 3.

[0042] It is also considered that, due to the existence of grooves and welding points at the bottom of the circuit board 3, during the cleaning process of the bottom of the circuit board 3 by the brush wheel 103, the end of the soft bristles is easy to hook on the groove and welding point position at the bottom of the circuit board 3, and during the gradual movement of the circuit board 3 to the right, the circuit board 3 is easy to pull out the stuck soft bristles from the brush wheel 103, and then the bristles are carried out from the right side of the conveying belt 102 together with the circuit board 3, and there is also the phenomenon that the workers observe whether there are bristles attached to each circuit board 3, in order to avoid this phenomenon, by setting the first clamping plate 109 and the second clamping plate 110 on the brush wheel 103, and initially, the first clamping plate 109 is under the action of the spring telescopic rod, so that the adjacent first clamping groove 10901 and the second clamping groove 11001 are staggered under the action of the spring telescopic rod, as shown in Figure 6 , and then the bristles are clamped, when the bristles are clamped at the bottom of the circuit board 3, the end of the bristles is clamped by the first clamping groove 10901 and the second clamping groove 11001, and the second fixed point is provided by the first clamping groove 10901 and the second clamping groove 11001, so that the bristles are difficult to be pulled out from the brush wheel 103 by the circuit board 3, and are stopped on the brush wheel 103 under the action of the first clamping groove 10901 and the second clamping groove 11001, thereby avoiding the phenomenon of bristle residue at the bottom of the circuit board 3, and further improving the cleaning effect of the device on the circuit board 3. During this process, considering that the bristles are easy to knot and entangle after long-term use, the comb plate 107 and the rubbing plate 108 are used to cooperate with each other to rub and comb the knotted and entangled bristles before cleaning the circuit board 3, prevent the knotted bristles from accumulating too much dust, and improve the cleaning effect on the circuit board 3.

[0043] Example 2: based on example 1, as shown in Figure 1 and Figure 7 , it further includes an air pipe 201; a plurality of air pipes 201 are communicated in the collecting box 104 located at the right side of the brush wheel 103, and the air pipes 201 are communicated with the external air suction device.

[0044] After the bottom of the circuit board 3 is cleaned, when the soft bristles on the brush wheel 103 contact the comb teeth of the collecting box 104 on the right side, the comb teeth on the collecting box 104 can clean the bristles, but when the brush wheel 103 makes the bristles rotate through the comb teeth on the collecting box 104, the bristles will rebound, and part of the dust will be bounced up and dispersed to the outside. Considering that during this process, the circuit board 3 passes through the ion fan 2, and part of the dust dispersed to the outside is easy to reattach to the circuit board 3, in order to avoid this phenomenon, the external air suction device is started to suck air through the air pipe 201, so that a downward suction force is generated in the collecting box 104, and then the dust is sucked, so that the dust cannot be dispersed to the outside, and part of the dust dispersed to the outside is easy to reattach to the circuit board 3.

[0045] The embodiments of the present application are described in detail above with reference to the accompanying drawings, but the present application is not limited to the above-described embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the spirit of the present application.
