Referring to the drawings, the present invention provides a device for processing a uniform liquid on a printed circuit board, which is used for processing the printed circuit board, wherein the printed circuit board is sheet-shaped and has a surface to be processed, wherein the printed circuit board may have one surface to be processed or two opposite surfaces to be processed. The printed circuit board homogenizing treatment device is particularly used for treating a to-be-treated surface of a printed circuit board which is soaked with a liquid medicine or is soaked with the liquid medicine.
Referring to fig. 1, the device for processing uniform liquid on printed circuit board comprises a material loading mechanism 10, a driving mechanism 30, and a positioning mechanism 20.
The material loading mechanism 10 is used for fixing a printed circuit board, and a central axis of the material loading mechanism 10 extends in a horizontal direction so that the printed circuit board is vertically arranged, and it can be understood that the vertical arrangement means that a surface to be processed of the printed circuit board is perpendicular to a horizontal plane or approximately perpendicular to the horizontal plane.

The loading mechanism 10 has a disk shape, and the disk shape may be a right disk shape or an elliptical disk shape. Preferably, the central axis of the loading mechanism 10 is perpendicular to the surface to be processed of the printed circuit board, and when the loading mechanism 10 can rotate around its central axis, i.e. its central axis is the rotation axis, the printed circuit board can rotate along with the rotation of the loading mechanism 10.
Referring to fig. 1, specifically, the material loading mechanism 10 includes a material loading tray 11 and a fixing member 12 disposed on the material loading tray 11 and used for fixing the printed circuit board. The material loading disc 11 is disc-shaped, and the material loading disc 11 has a first side surface, a second side surface and an edge surface, wherein the first side surface and the second side surface are oppositely arranged and can be arranged in parallel or approximately parallel. The central axis of the material loading tray 11 is the central axis of the material loading mechanism 10, and the edge surfaces circumferentially surround the first side surface and the second side surface and are opposite to the central axis. Preferably, the first side and the second side are both perpendicular to the horizontal plane, so that the edge faces are equally wide. The fixing member 12 can tension the printed circuit board in a planar shape to prevent the groove from being formed on the surface to be processed and influencing the flow of the liquid medicine on the printed circuit board. In this embodiment, the fixing member 12 includes a plurality of fixing jigs attached to the tray 11, and the plurality of fixing jigs are arranged along the circumferential direction of the printed circuit board to uniformly fix the printed circuit board. The fixing member 12 may suspend the pcb in the air, or attach the pcb to the first side or the second side of the tray 11 with the surface to be processed facing outward, so as to facilitate the processing of the liquid medicine. In this embodiment, the material loading tray 11 is provided with a through hole 101 penetrating along the rotation axis, the fixing member 12 is used for fixing the printed circuit board to the through hole 101, and the through hole 101 is free from the surface to be processed. Two pending faces of printed circuit board do not all receive the sheltering from of year charging tray 11 and touch like this, are convenient for the later stage to carry out other processing procedure to printed circuit board. The material carrying disc 11 is further provided with an avoiding hole 102 so as to facilitate taking and hanging of the material carrying disc 11 by external equipment. In this embodiment, the rotation of the tray 11 means that the tray 11 rotates around its central axis.
Referring to fig. 1, the positioning mechanism 20 at least includes a first positioning wheel 21 and a second positioning wheel 22, in this embodiment, the positioning mechanism 20 only includes the first positioning wheel 21 and the second positioning wheel 22, and in other embodiments, the positioning mechanism 20 may further include other positioning wheels capable of positioning the material loading tray 11.
The rotation axis of the first positioning wheel 21 and the rotation axis of the second positioning wheel 22 both extend along the horizontal direction and are parallel to each other, and the first positioning wheel 21 and the second positioning wheel 22 can jointly support the material loading mechanism 10. It can be understood that the material loading tray 11 can be placed on the first positioning wheel 21 and the second positioning wheel 22, that is, the edge surfaces of the material loading tray can abut against the first positioning wheel 21 and the second positioning wheel 22, wherein in the present embodiment, the first positioning wheel 21 and the second positioning wheel 22 are located on the same plane, and the rotation axis of the first positioning wheel 21 is parallel to the central axis of the material loading mechanism 10, so as to facilitate the alignment and rotation of the material loading tray 11. In other embodiments, the first positioning wheel 21 and the second positioning wheel 22 may not be located on the same plane.
The positioning mechanism 20 is switchable between a first state and a second state. Under the condition that the loading mechanism 10 is placed on the first positioning wheel 21 and the second positioning wheel 22, when the positioning mechanism 20 is in the first state, the loading mechanism 10 is spaced from the driving mechanism, that is, the loading mechanism 10 is not driven or controlled by the driving mechanism 30; when the positioning mechanism 20 is in the second state, the driving mechanism 30 can drive the material loading mechanism 10 to rotate around the central axis thereof, that is, when the positioning mechanism 20 is in the second state, the first positioning wheel 21 and the second positioning wheel 22 can jointly make the material loading tray 11 contact with the driving mechanism 30, so that the driving mechanism 30 can drive the material loading tray 11 to rotate. When the material loading disc 11 rotates, the first positioning wheel 21 and the second positioning wheel 22 can both rotate along with the rotation of the material loading mechanism 10, that is, the first positioning wheel 21 and the second positioning wheel 22 are both driven wheels of the material loading disc 11. It should be noted that, when the positioning mechanism 20 is in the second state, the first positioning wheel 21 and the second positioning wheel 22 can position the material loading tray 11 to limit the radial movement thereof, or the first positioning wheel 21, the second positioning wheel 22 and the driving mechanism 30 can position the material loading tray 11 together to limit the radial movement thereof. Wherein the driving mechanism 30 is fixed in position and is also movable in position to contact or separate from the tray 11.
The printed circuit board passes through the fixed vertical setting of carrying material mechanism 10, when positioning mechanism 20 is in the second state, actuating mechanism 30 can drive carrying material mechanism 10 and rotate, first locating wheel 21 and second locating wheel 22 can rotate along with carrying material mechanism 10's rotation, the rotation of carrying material mechanism 10 has been realized, printed circuit board rotates along with carrying material mechanism 10's rotation this moment, printed circuit board's face is after soaking the liquid medicine, the liquid medicine can flow under gravity or centrifugal force, printed circuit board's rotation can make liquid medicine evenly distributed on its face, and unnecessary liquid medicine can drip or be thrown away, avoid producing the pond effect, prevent that remaining liquid medicine from leading to the local area of face to handle excessively, avoided the liquid medicine to handle the inhomogeneous condition of effect to the upper and lower part of its face when printed circuit board is vertical simultaneously.
Wherein, first positioning wheel 21 can wait to switch between position and the first operation position at first, and second positioning wheel 22 can wait to switch between position and the second operation position at the second, and when positioning mechanism 20 was in the second state, first positioning wheel 21 was in first operation position and second positioning wheel 22 was in the second operation position. That is, when the positioning mechanism 20 is switched between the first state and the second state, the first positioning wheel 21 is switched between the first standby position and the first working position, and/or the second positioning wheel 22 is switched between the second standby position and the second working position. When the position of the first positioning wheel 21 or the second positioning wheel 22 changes, the material loading tray 11 also changes position to realize contact or separation with the driving mechanism 30.
In one embodiment, when the positioning mechanism 20 is in the first state, the first positioning wheel 21 is in the first waiting position and the second positioning wheel 22 is in the second waiting position. That is, when the positioning mechanism 20 is switched from the first state to the second state, the first positioning wheel 21 is switched from the first position to be determined to the first working position, and the second positioning wheel 22 is switched from the second position to be determined to the second working position, so as to change the position of the material loading tray 11 to be in contact with the driving mechanism 30.
In the present embodiment, when the positioning mechanism 20 is in the first state, the first positioning wheel 21 is in the first standby position and the second positioning wheel 22 is in the second working position. That is, when the positioning mechanism 20 is switched from the first state to the second state, the first positioning wheel 21 is switched from the first standby position to the first working position, and the second positioning wheel 22 is kept unchanged at the second working position. Thus, the material loading tray 11 can move to the position of abutting against the driving mechanism 30 through the position switching of the first positioning wheel 21, and the second positioning wheel 22 plays a limiting role.
In the present embodiment, the first working position is located above the first waiting position, the second working position is located above the second waiting position, and the driving mechanism 30 is located above the positioning mechanism 20. When the positioning mechanism 20 is switched from the first state to the second state, the positioning mechanism 20 can lift the material loading tray 11 upwards to contact with the driving mechanism 30, and when the positioning mechanism 20 is switched from the second state to the first state, the positioning mechanism 20 can enable the material loading tray 11 to descend to be separated from the driving mechanism 30.
Referring to fig. 1, preferably, the height of the first positioning wheel 21 in the first waiting position is the same as the height of the second positioning wheel 22 in the second waiting position, and the height of the first positioning wheel 21 in the first working position is the same as the height of the second positioning wheel 22 in the second working position. Thus, when the positioning mechanism 20 is in the first state, the material loading tray 11 can horizontally translate from the side onto the first positioning wheel 21, and the second positioning wheel 22 is now in the moving direction of the first positioning wheel 21, so as to limit the first positioning wheel 21 from moving further. The movement may be translation or rolling, and when the material loading tray 11 rolls onto the first positioning wheel 21 and abuts against the second positioning wheel 22, the first positioning wheel 21 and the second positioning wheel 22 rotate along with the rotation of the material loading tray 11. When the positioning mechanism 20 is in the second state, the first positioning wheel 21 lifts the material loading tray 11 until the first positioning wheel 21 is flush with the second positioning wheel 22, at this time, the lowest point of the material loading tray 11 is located between the first positioning wheel 21 and the second positioning wheel 22 in the vertical direction, and the highest points of the first positioning wheel 21 and the second positioning wheel 22 are higher than the lowest point of the material loading tray 11, so that the first positioning wheel 21 and the second positioning wheel 22 both limit the material loading tray 11 and limit the material loading tray 11 from rolling radially, so that the material loading tray 11 can rotate when the driving mechanism 30 drives the material loading tray 11 to rotate.
In other embodiments, the height of the first positioning wheel 21 and the height of the second positioning wheel 22 may be different when the positioning mechanism 20 is in the second state.
Referring to fig. 1, the driving mechanism 30 includes an active driving wheel 31, a driving motor 32 and a belt 33, the belt 33 is connected to the driving motor 32 and the active driving wheel 31, and the driving motor 32 can drive the active driving wheel 31 to rotate by driving the belt 33. When the positioning mechanism 20 is in the first state and the loading mechanism 10 is placed on the first positioning wheel 21 and the second positioning wheel 22, the loading mechanism 10 and the driving wheel 31 are spaced apart from each other, and when the positioning mechanism 20 is in the second state and the loading mechanism 10 is placed on the first positioning wheel 21 and the second positioning wheel 22, the driving wheel 31 can abut against the loading mechanism 10 and drive the loading mechanism 10 to rotate through rotation. Thus, the driving wheel 31 drives the material loading tray 11 to rotate through rotation, and the material loading tray 11 rotates. The driving wheel 31 may abut against the highest point of the material loading tray 11, or may abut against the side edge of the material loading tray 11, and when the positioning mechanism 20 is in the second state, the driving wheel 31, the first positioning wheel 21, and the second positioning wheel 22 may limit the radial movement of the material loading tray 11 together, so as to prevent the material loading tray 11 from separating from the positioning mechanism 20. The driving wheel 31 is connected with the driving motor 32 through the conveyor belt 33, so that the speed ratio can be changed, a speed reducer is formed, and the speed of the driving motor 32 transmitted to the driving wheel 31 is reduced.
Referring to fig. 1, in order to further limit the position of the material loading tray 11, the device for processing uniform liquid on a printed circuit board further includes a limiting wheel 40, the limiting wheel 40 can abut against the material loading mechanism 10 when the positioning mechanism 20 is in the second state, and can rotate along with the rotation of the material loading tray 11, and the limiting wheel 40, the driving wheel 31, the first positioning wheel 21 and the second positioning wheel 22 can limit the displacement of the material loading mechanism 10 together. It can be understood that, when the positioning mechanism 20 is switched from the first state to the second state, the material loading tray 11 is lifted upwards and abutted against the driving wheel 31 and the limiting wheel 40, wherein the highest point of the material loading tray 11 is located between the driving wheel 31 and the limiting wheel 40, so that the driving wheel 31 and the limiting wheel 40 clamp the material loading tray 11 together from above, and the first positioning wheel 21 and the second positioning wheel 22 clamp the material loading tray 11 from below, so as to further limit the radial movement of the material loading mechanism 10.
After the printed circuit board processing is completed, the positioning mechanism 20 also has a third state to facilitate the re-separation of the carrier tray 11 from the active drive wheel 31 and its removal from the positioning mechanism 20. In the present embodiment, when the positioning mechanism 20 is in the third state, the first positioning wheel 21 is in the first working position and the second positioning wheel 22 is in the second standby position. The positioning mechanism 20 can be switched from the second state to the third state, that is, the first positioning wheel 21 is kept at the first working position, the second positioning wheel 22 is switched from the second working position to the first waiting position, the material carrying tray 11 descends, and simultaneously, due to the height difference between the first positioning wheel 21 and the second positioning wheel 22, the first positioning wheel 21 generates a horizontal supporting force on the material carrying tray 11, so that the material carrying tray 11 rolls towards the direction from the first positioning wheel 21 to the second positioning wheel 22, and the material carrying tray 11 rolls down from the positioning mechanism 20 to enter the next process. The positioning mechanism 20 realizes the limiting treatment and the automatic conveying of the material loading tray 11 through the position change of the first positioning wheel 21 and the second positioning wheel 22.
It should be noted that the material loading tray 11 may be placed on the positioning mechanism 20 in the first state, and start to rotate after being driven by the driving mechanism 30, or may be in a rotating state all the time, and the driving mechanism 30 drives it to rotate continuously in the same direction.
Referring to fig. 1, in order to convey the material carrying tray 11 to the positioning mechanism 20, the device for processing uniform liquid on a printed circuit board further includes a first supporting slideway 50, the first positioning wheel 21 and the second positioning wheel 22 are sequentially located in the extending direction of the first supporting slideway 50, that is, the first positioning wheel 21 is located between the first supporting slideway 50 and the second positioning wheel 22, the first supporting slideway 50 is used for supporting the material carrying tray 11, the material carrying mechanism 10 can be placed on the first supporting slideway 50 and roll along the extending direction of the first supporting slideway 50, and when the positioning mechanism 20 is in the first state, the material carrying mechanism 10 can roll to the first positioning wheel 21 and the second positioning wheel 22 through the first supporting slideway 50. The first supporting slide way 50 plays a guiding role, the material carrying plate 11 can roll on the first supporting slide way 50 through the inertia effect and roll to the positioning mechanism 20 in the first state under the action of the inertia force, at the moment, the second positioning wheel 22 is located at the second operation position and can limit the material carrying plate 11 to continuously roll, when the positioning mechanism 20 is switched to the second state, the first positioning wheel 21 is switched to the first operation position, and the driving mechanism 30 drives the material carrying plate 11 to continuously rotate in the same direction.
