DETAILED DESCRIPTION

As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present invention. Therefore, the drawings and the description are considered to be exemplary in nature rather than limiting.

[0039] In the description of the present invention, it needs to be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present invention.

[0040] The embodiments of the present utility model will be described in detail below in combination with the drawings.

[0041] As Figures 1-4 shown, the utility model discloses a kind of micro motor production device, including conveying belt 1, and multiple mold clamping assemblies are equipped on conveying belt 1, multiple mold clamping assemblies are set on conveying belt 1 at equal intervals, mold seat 17 for accommodating PCB substrate is equipped in mold clamping assembly, and mold seat 17 can be fixed on conveying belt 1 by mold clamping assembly.

[0042] Mold seat 17 is cuboid, and mold clamping assembly includes four clamping plates 16 vertically arranged on conveying belt 1, the positional relationship between the four clamping plates 16 corresponds to the four side walls of mold seat 17, and when mold seat 17 is placed into mold clamping assembly, the four outer side walls of mold seat 17 are in contact with the four clamping plates 16 respectively.

[0043] The top surface of the mold base 17 is provided with a mold groove 21 matched with the shape of the PCB substrate, and the PCB substrate is placed in the mold groove 21. The top side wall of the mold groove 21 is provided with a slot, and a flexible rotating winding roller is rotatably arranged in the slot. The winding roller is provided with a torsional spring connected with the slot to enable elastic rotation. The winding roller is provided with a sealing film 20 wound thereon. The top of the mold groove 21 is slidably provided with a sliding rod 19, and the top end of the sliding rod 19 is vertically provided with a push rod 18. The sliding rod 19 is arranged along the length direction of the mold base 17 at the top of the mold groove 21, and the two ends of the sliding rod 19 are slidably connected with the top side walls of the mold groove 21, respectively. The sliding rod 19 can slide horizontally at the top of the mold groove 21, and the sliding rod 19 is connected with the sealing film 20. The sliding rod 19 can pull the sealing film 20 by sliding.

[0044] When the sliding rod 19 slides away from the slot at the top of the mold groove 21, the sliding rod 19 drives the sealing film 20 to be unwound from the winding roller. The sealing film 20 can block the top of the mold groove 21. When the sliding rod 19 contacts with the top side wall of the mold groove 21 away from the slot, the sealing film 20 completely blocks the top of the mold groove 21, so that the inside of the mold groove 21 is sealed, and impurities or dust in the external environment cannot enter the mold groove 21 to keep the PCB substrate clean. Because the winding roller is elastically rotatable, the winding roller can tighten the sealing film 20 to keep it taut. The sliding rod 19 and the top side walls of the mold groove 21 at the two ends have large sliding friction. The elastic force of the torsional spring on the winding roller is not enough to drive the winding roller to rotate to pull the sliding rod 19 to slide.

[0045] A base 2 is arranged above the conveying belt 1, and the base 2 is provided with a rectangular dust removal cover 6 at the bottom. The length direction of the dust removal cover 6 is parallel to the conveying direction of the conveying belt 1, and the bottom of the dust removal cover 6 is open.

[0046] Three vertical partition plates 7 are arranged in the length direction of the dust removal cover 6. The three partition plates 7 and the two side plates in the length direction of the dust removal cover 6 are arranged at equal intervals. The three partition plates 7 divide the inside of the dust removal cover 6 into four dust removal cavities 8. One dust removal mechanism is arranged in each of the four dust removal cavities 8. The dust removal mechanism comprises a support base 9 connected to the bottom of the base 2. The support base 9 is provided with a gas injection assembly and a dust suction assembly at the bottom. The gas injection assembly and the dust suction assembly are oppositely arranged.

[0047] The gas injection assembly comprises two gas injection pipes 12 connected to the bottom of the support base 9. The two gas injection pipes 12 are provided with gas seats at the bottom. The gas seats are provided with two gas injection nozzles 14 at the bottom, which are in communication with the two gas injection pipes 12, respectively. The gas injection nozzles 14 are obliquely arranged, and the gas outlet ends of the bottom ends of the gas injection nozzles 14 are inclined to the direction of the dust suction assembly.

[0048] The dust suction assembly comprises a dust suction pipe 10 connected to the bottom of the support 9, and a dust suction cover 11 is arranged at the bottom end of the dust suction pipe 10. The dust suction cover 11 is arranged obliquely, and the bottom end of the dust suction cover 11 is obliquely opened towards the direction of the air jet assembly. The air jet pipe 12 is connected to an air source (not shown in the figure), and the dust suction pipe 10 is connected to a dust collector (not shown in the figure). When the PCB substrate passes through the dust removal cavity 8, the oblique air jet nozzle 14 sprays air flow obliquely to the PCB substrate, and the dust suction cover 11 sucks air flow and dust on the opposite side.

[0049] The four dust removal mechanisms are arranged in different directions, and the air jet nozzles 14 of the four dust removal mechanisms are respectively located on the front, rear, left and right sides of the PCB substrate, so that the air jet nozzles 14 of the four dust removal mechanisms respectively spray air flow to flush the PCB substrate from the front, rear, left and right sides of the PCB substrate.

[0050] The dust removal mechanism further comprises a trigger assembly arranged at the bottom of the side wall of the dust removal cavity 8 away from the conveying track of the conveying belt 1. The trigger assembly is a proximity switch 15. When the PCB substrate moves to the dust removal cavity 8 along with the conveying belt 1, the PCB substrate first slides through the bottom of the proximity switch 15, and the proximity switch 15 triggers to send an electrical signal to the air source and the dust collector. The air jet assembly and the dust suction assembly operate to perform dust removal work. Since the conveying speed of the conveying belt 1 is fixed, the operation time of the air jet assembly and the dust suction assembly can be set in advance, so that the air jet assembly and the dust suction assembly stop operating after the PCB substrate completely slides away from the bottom opening of the dust removal cavity 8.

[0051] The bottom of the base 2 on both sides of the dust removal cover 6 is respectively provided with an opening mechanism and a closing mechanism. The opening mechanism, the dust removal cover 6 and the closing mechanism are sequentially arranged according to the conveying track of the conveying belt 1. The opening mechanism opens the sealing film 20 at the top of the mold seat 3, and the closing mechanism closes the sealing film 20 at the top of the mold seat 17.

[0052] The mold opening mechanism comprises a mold opening seat 3 located above the conveying belt 1, and a pull rod 4 connected to the base 2 at the top of the mold opening seat 3. The bottom of the mold opening seat 3 is provided with a mold opening groove 22 matched with the push rod 18, and the height of the mold opening groove 22 is matched with the push rod 18. When the mold seat 17 is conveyed on the conveying belt 1, the push rod 18 slides in the mold opening groove 22. The mold opening groove 22 penetrates in the conveying direction of the conveying belt 1, and comprises a flared section in the shape of a right trapezoid and a first straight section parallel to the conveying track of the conveying belt 1. The first straight section is in communication with the flared section at a right angle, and the position of the first straight section is matched with the position of the push rod 18 when the sealing film 20 is in the open state. When the push rod 18 slides into the flared section, no matter where the initial state of the push rod 18 is, the push rod 18 is always inside the flared section. With the movement of the conveying belt 1, the push rod 18 slides and finally slides into the first straight section. In the first straight section, the push rod 18 is located near the opening at the top of the mold groove 21. At this time, the slide rod 19 is located near the opening, the sealing film 20 is wound by the winding roller, the top of the mold groove 21 is in the open state, and the mold groove 21 is opened by sliding the push rod 18 through the mold opening groove 22.

[0053] The mold closing mechanism comprises a mold closing seat 5 located above the conveying belt 1, and a pull rod 4 connected to the base 2 at the top of the mold closing seat 5. The bottom of the mold closing seat 5 is provided with a mold closing groove 23 matched with the push rod 18, and the height of the mold closing groove 23 is matched with the push rod 18. When the mold seat 17 is conveyed on the conveying belt 1, the push rod 18 slides in the mold closing groove 23. The mold closing groove 23 penetrates in the conveying direction of the conveying belt 1, and comprises a second straight section, an inclined section and a third straight section. The second straight section and the third straight section are both parallel to the conveying direction of the conveying belt 1. The second straight section is on the same straight track as the first straight section, and the position of the third straight section corresponds to the position of the push rod 18 when the sealing film 20 at the top of the mold groove 21 is closed. When the push rod 18 slides from the second straight section to the third straight section through the inclined section, the push rod 18 drives the slide rod 19 to slide away from the groove and contact the sidewall at the top of the mold groove 21, so that the push rod 18 drives the sealing film 20 to close the top of the mold groove 21.

[0054] The conveyor belt 1 moves, driving multiple mold bases 17 to be conveyed. The mold bases 17 pass sequentially through the mold opening mechanism, the bottom of the four dust cleaning chambers 8, and the mold closing mechanism. At the mold opening mechanism, regardless of whether the sealing film 20 on the mold base 17 is closed, after the mold base 17 moves with the conveyor belt 1 and the lever 18 slides past the mold opening groove 22, the slide bar 19 is close to the opening, at which time the top of the mold groove 21 is in the open state. As the mold base 17 passes the bottom of the four cleaning chambers 8 sequentially with the conveyor belt 1, the triggering components on the sides of the four cleaning chambers 8 are triggered in sequence, causing the air jet components and dust suction components inside the four cleaning chambers 8 to operate. The air jet components blow out gas to wash the PCB substrate, causing impurities or dust on the PCB substrate to be washed away. The dust suction components suck up the impurities or dust washed away by the airflow, preventing dust or impurities from escaping. The cleaning hood 6 is set to prevent impurities or dust washed away by the airflow from being scattered into the environment. The air jet nozzles 14 of the air jet components in the four cleaning chambers 8 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 cleaning of the PCB substrate. After the mold base 17 leaves the bottom of the four cleaning chambers 8 and passes the mold closing mechanism, the lever 18 slides past the mold closing groove 23. After the lever 18 moves, the slide rod 19 slides to the side wall of the mold groove 21 far away from the groove. The slide rod 19 drives the sealing film 20 to close the top of the mold groove 21, so that the PCB substrate after cleaning is in a closed environment to prevent secondary contamination by impurities or dust.

[0055] The PCB substrate of this invention is placed in the mold base 17, which can be sealed or opened. Through the set mold opening mechanism and mold closing mechanism, the mold base 17 is automatically opened before dust removal to achieve dust removal of the PCB substrate. After dust removal, the mold base 17 is automatically closed to prevent external impurities or dust from re-attaching to the PCB substrate. This invention can automatically clean the PCB substrate of the micro motor. Compared with the traditional manual dust removal operation, the efficiency of the dust removal operation is greatly improved. In addition, because the surface of the PCB substrate is uneven, multiple sets of dust removal mechanisms are used to brush the PCB substrate from different angles to avoid impurities or dust in the uneven parts of the PCB substrate surface not being brushed away by the airflow, resulting in poor dust removal effect. During the dust removal process, the dust removal cover 6 is set to prevent dust swept down by the airflow from being scattered into the environment.

[0056] 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.
