Description

Technical Field

[0001] This utility model relates to the field of micro motor technology, specifically to a micro motor PCB substrate cleaning device. Background Technology

[0002] Micro motors, also known as miniature motors, are motors with a diameter of less than 160mm or a rated power of less than 750mW. Micro motors are commonly used in control systems or transmission machinery loads to perform functions such as detection, analysis, amplification, execution, or conversion of electromechanical signals or energy.

[0003] In the existing technology, the PCB substrate used in the production of micro motors needs to be cleaned. Currently, the cleaning is usually done manually. The operator wipes the PCB substrate and then uses an air gun to rinse it. The work efficiency is not only low, but the airflow from the air gun rinsing the PCB substrate will carry impurities or dust into the environment, causing an increase in the amount of dust in the environment.

[0015] Optionally, the dust removal hood is rectangular in shape, and the length direction of the dust removal hood is parallel to the conveying direction of the conveyor belt.

[0016] Optionally, the cleaning hood has multiple vertically arranged partitions in its length direction.

Therefore, they should not be construed as limiting this invention.

[0029] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0030] like Figure 1 and Figure 2 As shown, this utility model discloses a micro motor PCB substrate cleaning device, including a conveyor belt 1 and a base 2 above the conveyor belt 1.

[0031] The base 2 is equipped with a brushing mechanism at its bottom. The brushing mechanism includes a first brushing roller 3 and a second brushing roller 4 that are rotatably mounted. Both the first brushing roller 3 and the second brushing roller 4 are arranged horizontally and perpendicular to the conveying direction of the conveyor belt 1. The first brushing roller 3 and the second brushing roller 4 are arranged sequentially according to the conveying direction of the conveyor belt 1. The first brushing roller 3 is covered with brushing strips, and the second brushing roller 4 is covered with brush bristles.

[0032] Both sides of the first brush roller 3 and the second brush roller 4 are rotatably supported. The supports are provided with support rods connected to the base 2, and the supports are also provided with motors that drive the first brush roller 3 or the second brush roller 4 to rotate.

[0033] The base 2 on the side of the second brushing roller 4 away from the first brushing roller 3 is provided with a rectangular cleaning cover 5. The length of the cleaning cover 5 is parallel to the conveying direction of the conveyor belt 1, and the bottom of the cleaning cover 5 is open.

[0034] The cleaning hood 5 has three vertically arranged partitions 6 inside its length direction. The three partitions 6 and the two side plates on both sides of the cleaning hood 5 are arranged at equal intervals. The three partitions 6 divide the cleaning hood 5 into four cleaning chambers 7. When the PCB substrate for producing micro motors is conveyed on the conveyor belt 1, it first passes through the first brushing roller 3 and the second brushing roller 4 in sequence, and then passes through the bottom of the four cleaning chambers 7 in sequence.

[0035] Each of the four dust removal chambers 7 is equipped with a dust removal mechanism. The dust removal mechanism includes a support 8 connected to the bottom of the base 2. The bottom of the support 8 is equipped with an air jet assembly and a dust suction assembly, which are arranged opposite to each other.

[0036] The jet assembly includes two jet pipes 9 connected to the bottom of the support 8. The bottom of the two jet pipes 9 is provided with an air seat. The bottom of the air seat is provided with two jet nozzles 11 that are respectively connected to the two jet pipes 9. The jet nozzles 11 are inclined and the air outlet end of the bottom of the jet nozzles 11 is inclined towards the dust collection assembly.

[0037] The vacuuming assembly includes a vacuum pipe 12 connected to the bottom of the support 8. A vacuum hood 13 is located at the bottom of the vacuum pipe 12, and the vacuum hood 13 is angled, with its bottom opening tilted towards the jet assembly. The jet pipe 9 is connected to an air source (not shown in the figure), and the vacuum pipe 12 is connected to a vacuum cleaner (not shown in the figure). When the PCB substrate passes through the cleaning chamber 7, the airflow ejected from the angled jet nozzle 11 obliquely washes the PCB substrate, while the vacuum hood 13 draws in airflow and dust from the opposite side.

[0038] The four dust removal mechanisms are arranged in different positions. The air nozzles 11 of the four dust removal mechanisms are located at the front, back, left and right sides of the PCB substrate, respectively, so that the air nozzles 11 of the four dust removal mechanisms spray airflow from the front, back, left and right sides of the PCB substrate to wash the PCB substrate.

[0039] The dust removal mechanism also includes a triggering component, which is located at the bottom of the side wall of the dust removal chamber 7 near the dust brushing mechanism. The triggering component is a proximity switch 14. When the PCB substrate moves to the dust removal chamber 7 with the conveyor belt 1, the PCB substrate first slides past the bottom of the proximity switch 14. The proximity switch 14 triggers and sends an electrical signal to the air source and the vacuum cleaner. The air jet component and the vacuuming component operate to perform the dust removal operation. Since the conveying speed of the conveyor belt 1 is fixed, the running time of the air jet component and the vacuuming component can be set in advance so that the air jet component and the vacuuming component stop operating after the PCB substrate has completely slid away from the bottom opening of the dust removal chamber 7.

[0040] When the PCB substrate conveyed on the conveyor belt 1 passes through the first dust brush roller 3 and the second dust brush roller 4, the rotating first dust brush roller 3 and the second dust brush roller 4 clean the PCB substrate, brushing off some of the impurities or dust on the PCB substrate. The impurities or dust on the PCB substrate are brushed by the bristles of the second dust brush roller 4, so that the impurities or dust no longer adhere to the PCB substrate, which is beneficial to the subsequent dust cleaning operation of the dust cleaning mechanism. When the PCB substrate is conveyed to the dust removal mechanism, it passes through the bottom of the four dust removal chambers 7 in sequence. During this process, the triggering components on the sides of the four dust removal chambers 7 are triggered in sequence to make the air jet components and dust suction components in the four dust removal chambers 7 operate. The air jet components blow out air to wash the PCB substrate, so that the impurities or dust on the PCB substrate that are brushed by the bristles are washed away. The dust suction components suck up the impurities or dust washed away by the airflow to prevent dust or impurities from escaping. The dust removal hood 5 is set to prevent the impurities or dust washed away by the airflow from being scattered into the environment. The air jet nozzles 11 of the air jet components in the four dust removal chambers 7 are located at the front, back, left and right sides of the PCB substrate, respectively, so that the airflow washes the PCB substrate from different angles, realizing multi-angle dust removal of the PCB substrate.

[0041] This invention can automatically clean the PCB substrate of micro motors. Compared with traditional manual dust removal, the efficiency of dust removal is greatly improved. Since the surface of the PCB substrate is uneven, multiple dust removal mechanisms are used to brush the PCB substrate from different angles to avoid impurities or dust in the uneven areas of the PCB substrate surface not being washed away by the airflow, resulting in poor dust removal effect. During the dust removal process, the dust removal hood 5 is set to prevent dust swept down by the airflow from being scattered into the environment.

[0042] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the technical solutions of this utility model. Any technical solution that can be implemented based on the above embodiments without creative effort should be considered to fall within the scope of protection of this utility model patent.
