Description

Screen frame adjusting mechanism, printing machine and working method of printing machine
Technical Field
The invention relates to the technical field of printing, in particular to a screen frame adjusting mechanism, a printing machine and a working method of the printing machine.
Background
At present, each photovoltaic manufacturer mostly adopts a screen printing method to prepare electrodes and electric fields for a battery piece, so that the battery piece and a screen frame need to be matched and aligned, the matching and aligning precision is high, and the operation can not be basically completed by manpower. The traditional printing alignment device is realized by adjusting the position of a printing screen relative to a battery piece or a silicon chip, and is generally realized by adjusting the relations of X-axis displacement, Y-axis displacement and angle of the printing screen, wherein the X-axis displacement and the Y-axis displacement are linear movements and are not difficult to adjust, and the angle movement is difficult to realize rotary movement by adopting a central shaft driving structure due to the structural limitation of the actual printing screen. In the prior art, the mechanism can be divided into two types according to the driving principle of a printing screen, one type is that a motor, a lead screw (or a linear motor), an elastic guide rail (or a cross rail) are respectively arranged on two sides of the printing screen, and the elastic guide rail is slightly deformed in a pushing and pulling mode so as to adjust the angle of the printing screen, so that the precision is not high, the adjustment angle is very small, and the requirement is difficult to meet; meanwhile, the driving mode also needs to install the Y-axis drive on the X-axis drive, the number of transmission stages is large, and excessive loss, complex structure and difficult maintenance are caused in the using process. The other type is that a grating ruler is required to be installed at the arc-shaped guide rail to acquire the rotation angle of the printing screen through the matching of a motor and the arc-shaped guide rail. For example, patent CN201010507055.3 discloses an angularly adjustable printing screen and an angular adjustment device thereof, which change the measurement and control of angular movement from a rotated angle to an arc distance traveled by a position away from the center of rotation through the cooperative use of an arc guide rail, a grating ruler and a reading head thereof.
Disclosure of Invention
The present invention aims to adopt a more direct net frame angle rotation mode.
To this end, a first aspect of the present invention provides a frame adjusting mechanism comprising: at least two first driving members without direct linkage relation; each first driving piece drives the screen frame to do asynchronous motion or reverse motion simultaneously so as to enable the screen frame to rotate.
In the technical scheme, when the first driving parts are driven asynchronously or reversely on the screen frame, the driving forces in different directions of the X axis occur between the at least two driving parts, so that the rotation of the screen frame is realized. For example, when the battery piece has a position deviation, the screen frame can be ensured to rotate through the process, so that the battery piece is aligned with the screen frame, the variability of the position adjustment of the screen frame is improved, the printing efficiency and quality of the battery piece are ensured, and the yield of the battery piece after the printing is finished is improved. And each first driving piece has few transmission stages, so that the loss of driving force is reduced, the rotating process is ensured to be completed quickly and efficiently, and the battery piece is aligned accurately.
In addition, the screen frame is driven to rotate by at least two first driving parts without direct linkage, so that the alignment accuracy of the battery pieces is ensured, and the printing quality and efficiency of the battery pieces are improved; and simple structure makes things convenient for follow-up maintenance and the change to first driving piece.
The screen frame adjusting mechanism according to the above technical solution of the present invention may further have the following additional technical features:
in the screen frame adjusting mechanism provided by the invention, the screen frame adjusting mechanism further comprises at least one second driving piece; the first driving piece is used as a driving force source for realizing rotation of the screen frame and movement in the X axial direction, the second driving piece is used as a driving force source for realizing movement in the Y axial direction of the screen frame, direct linkage relation does not exist between the first driving piece and the second driving piece, and the screen frame can be ensured to rotate and/or move. On one hand, when the conveying position of the battery piece deviates from the designated position, the position and the angle of the screen frame and the battery piece are timely adjusted by driving the screen frame to rotate and/or move, so that the position of the screen frame is matched with the position of the battery piece, the printing efficiency and the printing quality of the battery piece are further improved, the yield of the battery piece after the printing is finished is improved, and the generation of defective molded battery pieces is further reduced or avoided; on the other hand, the screen frame is adjusted automatically, the matching and aligning precision of the screen frame and the battery piece is ensured, and the printing quantity of the battery piece is improved.
On the basis, each driving piece is suitable for linkage of the screen frame and no direct linkage relation exists between the driving pieces. That is, the driving members (including the first driving members, the second driving members and the first driving members and the second driving members) are separately and independently arranged, so that on one hand, the adjustment of the driving members on the screen frame is realized, the transmission stages are reduced, the transmission efficiency is improved, and the consumption of mechanical energy is reduced; on the other hand, when the driving parts independently operate, the linkage state is still kept, the horizontal displacement of the screen frame can be realized, and the rotation of the screen frame can be realized through the linkage of the first driving parts, so that the variability of the position adjustment of the screen frame is improved, and the printing device is suitable for the printing of the battery pieces at all positions. In addition, in the scheme, the screen frame adjusting mechanism divides the adjusting angle and the displacement of the screen frame into the stroke of each first driving piece driving the screen frame on the X axis and the stroke of each second driving piece driving the screen frame on the Y axis, and simultaneously maintains the degrees of freedom of the screen frame on the X axis and the Y axis respectively so as to realize the rotation of the screen frame.
In the technical scheme, the first driving part can drive the screen frame to move along the X-axis direction, but the screen frame can freely move on the Y-axis simultaneously; the second driving piece can drive the screen frame to move along the Y-axis direction, but the screen frame can freely move on the X-axis at the same time; and the X-axis direction and the Y-axis direction are perpendicular to each other.
Specifically, the first driving member is suitable for driving the screen frame to move along the X-axis direction. That is to say, first driving piece is as drive structure, can drive the screen frame and remove along the X axle direction, and when the battery piece position of X axle direction appeared deviate, adjust the screen frame through first driving piece at X axle direction position to make the screen frame move in X axle direction, with this and battery piece counterpoint, accurate regulation screen frame X axle position. Specifically, the second driving member is suitable for driving the screen frame to move along the Y-axis direction. That is to say, the second driving piece is as drive structure, can drive the screen frame and remove along the Y axle direction, when the battery piece position deviation of Y axle direction appears, adjust the screen frame in Y axle direction position through the second driving piece, thereby make the screen frame in the removal of Y axle direction, thereby correspond the position of battery piece, accurate regulation screen frame Y axle position, this process has ensured that the screen frame can realize X axial removal or Y axial removal, further improvement the variability of screen frame position, thereby adapt to the battery piece counterpoint process of different positions.
On the basis, the X-axis direction and the Y-axis direction are perpendicular to each other. That is, when the driving directions of the first driving element and the second driving element are perpendicular, the first driving element and the second driving element realize a linkage process. For example, when the deviated position of the battery piece cannot realize alignment by adjusting the independent movement of the screen frame in the X-axis direction or the Y-axis direction, the screen frame is driven by the first driving parts to synchronously move or reversely move in the X-axis direction, so that the screen frame rotates by an angle; then the second driving part drives the screen frame to move along the Y-axis direction and/or the first driving part drives the screen frame to move along the X-axis direction, so that the screen frame is translated, the alignment between the screen frame and the position of the battery piece is further realized, the alignment accuracy of the screen frame is improved, and the printing quality of the battery piece is ensured. Of course, the first driving member and the second driving member can be driven simultaneously, so that the rotation and the movement of the screen frame can be simultaneously performed.
In the above solution, the driving members (including the first driving member and/or the second driving member) are distributed along the circumferential direction of the frame; the driving parts are arranged along the split body and are positioned on the same horizontal plane, especially on the same height.
In this solution, the drive elements are distributed along the circumference of the frame. That is to say, each driving piece sets up the distribution along the circumference of net frame, guarantees that the driving piece is orderly installed on the net frame, and consequently when damage appears in one of them driving piece, only need with the driving piece of damage take off can to swift convenient change and the maintenance of accomplishing the driving piece.
In the technical scheme, the driving parts are arranged separately and are positioned on the same plane, so that the stability of the screen frame during rotation or movement can be kept. That is to say, the driving pieces are independent of each other, so that on one hand, the transmission stages of the driving pieces can be reduced, thereby avoiding overlarge mechanical loss caused by more transmission stages and reducing the electric energy consumption of the driving pieces; on the other hand ensures that the driving piece is located the coplanar, can guarantee that X axial drive power and Y axial drive power to the screen frame are in same horizontal plane to reduce the production of moment of torsion between X axial drive power and the Y axial drive power, guarantee the steady rotation of screen frame and/or remove, avoided the driving piece to take place the conflict of inside drive power, prolonged the life of driving piece, reduced the maintenance number of times.
In the above technical solution, each first driving member includes: the screen frame adjusting mechanism also comprises a substrate, and the servo motor is fixed below the substrate; the ball screw is positioned on the output shaft of the servo motor; the lead screw nut connecting block is positioned on the ball screw to realize linear motion; the guide rail assembly is respectively connected with the lead screw nut connecting block and the screen frame; and the servo motor is suitable for driving the ball screw to rotate, and the guide rail assembly is enabled to perform linear motion under the action of the screw nut connecting block so as to drive the screen frame to rotate and/or move. The second driving piece and the first driving piece have the same structure and different installation positions, so that the moving directions of the screen frame driven by the second driving piece are different. The first driving part drives the screen frame to complete rotation or X-axis movement, the second driving part drives the screen frame to complete Y-axis movement, and the processes can occur simultaneously or sequentially.
In this technical scheme, the driving piece includes servo motor, ball screw and screw-nut connecting block. Through the rotation of servo motor drive end, driving ball and rotating to make screw nut connecting block realize rectilinear movement. On one hand, the reciprocating motion of the lead screw nut connecting block is realized in a rotating mode, and the mounting space of the driving piece can be reduced, so that sufficient operation space is provided for overhauling and maintenance, and the subsequent overhauling and maintenance of the driving piece are facilitated; on the other hand, the transmission form is simple and efficient, and the reduction of the transmission stage number can reduce the mechanical energy consumption in the transmission process, thereby ensuring the reduction of the electric energy consumption of the motor, saving the processing cost and improving the utilization rate of the electric energy.
In the above technical solution, the guide rail assembly includes: the first guide rail part is used for realizing the degree of freedom of the screen frame in the X-axis direction or the Y-axis direction; the second guide rail part is used for realizing the degree of freedom of the screen frame in the X-axis direction or the Y-axis direction; and the outer ring flange of the crossed roller bearing is fixed on the second guide rail piece, and the inner ring flange of the crossed roller bearing is connected with the net frame.
In this aspect, the guide track assembly includes a first guide track member, a second guide track member, and a cross roller bearing. That is, the first rail member ensures the degree of freedom of the screen frame in the X-axis direction or the Y-axis direction, thereby enabling the screen frame to move smoothly. The second guide rail piece ensures the freedom degree of the screen frame in the X-axis direction or the Y-axis direction, so that the screen frame can move stably by matching with the operation of the first guide rail piece. The crossed roller bearings can be matched with the movement of the first guide rail part and the second guide rail part, so that the rotation process of the screen frame is completed.
In the above technical aspect, the first rail member includes: the first guide rail is arranged on the lead screw nut connecting block through a first guide rail connecting piece; the first sliding block is fixed on the base plate and is suitable for the first guide rail to slide; and the second rail member comprises: the second guide rail is perpendicular to the first guide rail and is fixed with an outer ring flange of the crossed roller bearing through a second guide rail connecting piece; and the second sliding block is fixed on the other side of the feed screw nut connecting block and is suitable for the second guide rail to slide. In the present invention, the first guide rail may be fixed to the base plate as required, and the first guide rail may move along the first slider, so that the first guide rail member and the second guide rail member in the guide rail assembly may be mounted in various ways. Meanwhile, the guide rail assemblies respectively connected with the first driving piece and the second driving piece have differences due to different installation directions, but the functions and principles of the guide rail assemblies are basically the same. Therefore, the guide rail assembly is within the scope of the present application as long as the guide rail assembly is present in order to achieve the degrees of freedom of the screen frame in the X-axis direction and the Y-axis direction, i.e., the screen frame is controlled by the driving member in the X-axis direction and maintains the degrees of freedom in the Y-axis direction, or the screen frame is controlled by the driving member in the Y-axis direction and maintains the degrees of freedom in the X-axis direction.
In this embodiment, the first and second track members are identical in construction. But the second rail is perpendicular to the first rail. That is to say, when the first guide rail part moves under the driving of the driving part, the second driving part is always perpendicular to the first guide rail part, so that the linkage of the first guide rail and the second guide rail is ensured, and the screen frame can complete the movement in the X-axis direction or the Y-axis direction.
In the above technical solution, the movement process that the first driving member and the second driving member drive the screen frame to rotate and/or move is as follows:
moving in the X axial direction: the lead screw nut connecting blocks on the two first driving pieces synchronously move towards the head end of the ball screw in the same direction, so that the distances between the lead screw nut connecting blocks on the two first driving pieces and the servo motor are synchronously reduced, and the distances between the lead screw nut connecting blocks on the second driving pieces and the servo motor are basically unchanged; or the lead screw nut connecting blocks on the two first driving pieces synchronously move towards the tail end of the ball screw in the same direction, so that the distance between the lead screw nut connecting blocks on the two first driving pieces and the servo motor is synchronously increased, and the distance between the lead screw nut connecting blocks on the second driving piece and the servo motor is basically unchanged.
And Y-axis movement: the lead screw nut connecting blocks on the second driving pieces move towards the head ends of the ball screws, the distance between the lead screw nut connecting blocks on the second driving pieces and the servo motors is reduced, and the distance between the lead screw nut connecting blocks on the two first driving pieces and the servo motors is basically unchanged; or the lead screw nut connecting blocks on the second driving parts move towards the tail ends of the ball screws, the distance between the lead screw nut connecting blocks on the second driving parts and the servo motors is increased, and the distance between the lead screw nut connecting blocks on the two first driving parts and the servo motors is basically unchanged.
The X-axis movement and the Y-axis movement move simultaneously: the screw nut connecting blocks on the two first driving pieces synchronously move towards the head end of the ball screw in the same direction, and the screw nut connecting blocks on the second driving pieces move towards the tail end of the ball screw; the distance between the screw nut connecting block on the first driving piece and the servo motor is synchronously reduced, and the distance between the screw nut connecting block on the second driving piece and the servo motor is increased; or the screw nut connecting blocks on the two first driving pieces synchronously move towards the tail end of the ball screw in the same direction, and the screw nut connecting blocks on the second driving pieces move towards the head end of the ball screw; the screw-nut connecting block on the first driving piece and the interval of the servo motor are synchronously enlarged, and the screw-nut connecting block on the second driving piece and the interval of the servo motor are reduced.
The screen frame rotates: the screw nut connecting block on one of the first driving pieces moves towards the tail end of the ball screw, and the screw nut connecting block on the other one of the first driving pieces moves towards the head end of the ball screw; the distance between the screw nut connecting block on one of the first driving pieces and the servo motor is increased, and the distance between the screw nut connecting block on the other one of the first driving pieces and the servo motor is decreased.
Rotation and movement: the lead screw nut connecting block on one of the first driving pieces moves towards the tail end of the ball screw, the lead screw nut connecting block on the other one of the first driving pieces moves towards the head end of the ball screw, the lead screw nut connecting block on the second driving piece moves towards the tail end or the head end of the ball screw, the distance between the lead screw nut connecting block on one of the first driving pieces and the servo motor is increased, the distance between the lead screw nut connecting block on the other one of the first driving pieces and the servo motor is increased, and the distance between the lead screw nut connecting block on the second driving piece and the servo motor is decreased or increased.

The battery piece is conveyed to a station of a feeding position by the conveying mechanism; the turntable rotates 90 degrees, so that the battery piece rotates to the printing station, after the printing is finished, the turntable continues to rotate 90 degrees, so that the battery piece rotates to the discharging position, and the discharging is carried out through the conveying mechanism. In the whole process, the battery piece rotates 180 degrees in the same direction, so that the process that the battery piece corresponds to the adjusting mechanism is realized, and the battery piece can be smoothly and accurately printed.

Specifically, the detection mechanism can be an infrared detection device and is used for detecting the position of the battery piece on the turntable mechanism, so that the manual positioning process in an observation mode is omitted, the printing time is shortened, and the printing efficiency is improved. Specifically, the controller is electrically connected with the detection mechanism and the screen frame adjusting mechanism, and can control the screen frame adjusting mechanism to work according to the detection result of the detection mechanism so as to adjust the relative position of the screen frame and the battery piece. Therefore, on one hand, the information can be timely fed back to the detection mechanism and the screen frame adjusting mechanism, and the matching degree of the detection mechanism and the screen frame adjusting mechanism is increased, so that the printing quality is improved, and the processing time is shortened; on the other hand, the adjustment precision of the screen frame adjusting mechanism is improved, so that the screen frame adjusting mechanism can accurately correspond to the positions of the battery pieces, and the yield of battery piece forming is improved.

In this embodiment, when the first driving members 102 are driven asynchronously or reversely on the frame, driving forces in different directions of the X axis occur between at least two first driving members 102, so as to realize the rotation of the frame 134. For example, when the position of the battery piece deviates, the screen frame 134 can be ensured to rotate through the above process, so that the battery piece is aligned with the screen frame, the variability of the position adjustment of the screen frame is improved, the printing efficiency and quality of the battery piece are ensured, and the yield of the battery piece after the printing is finished is improved.

That is to say, when the driving directions of the first driving element 102 and the second driving element 104 are perpendicular, the first driving element 102 and the second driving element 104 realize a linkage process, specifically, as shown in fig. 19, 20, and 21, when the deviation position of the battery piece cannot be aligned by adjusting the movement of the screen frame 134 alone in the X axis direction or the Y axis direction, the screen frame is driven to rotate by the first driving element 102 at this time, so as to ensure the alignment process with the battery piece, further achieve the alignment with the battery piece position, improve the alignment accuracy of the screen frame 134, and ensure the printing quality of the battery piece. Of course, the driving sequence of the first driving element 102 driving the frame to move along the X axis and the second driving element 104 driving the frame to move along the Y axis and rotate the frame is not particularly limited, that is, the alignment process is within the protection scope of the present embodiment.

In this embodiment, the drive members 10 are distributed along the circumference of the frame 134. That is to say, the driving member 10 is arranged along the circumferential distribution of the screen frame 134, and the driving member 10 is ensured to be orderly installed on the screen frame 134, so that when a certain driving member 10 is damaged, the damaged driving member 10 is only required to be taken down, and therefore, the replacement and maintenance of the driving member 10 can be quickly and conveniently completed.
In this embodiment, each driving member 10 is separated and located on the same plane. That is to say, the driving members 10 are independent of each other, so that on one hand, the transmission stages of the driving members 10 can be reduced, thereby avoiding the excessive mechanical loss caused by more transmission stages and reducing the electric energy consumption of the driving members 10; on the other hand, the driving part 10 is ensured to be positioned on the same plane, and the X axial driving force and the Y axial driving force for the screen frame 134 can be ensured to be positioned on the same horizontal plane, so that the generation of torque force between the X axial driving force and the Y axial driving force is reduced, the stable rotation and/or movement of the screen frame 134 is ensured, the conflict of the internal driving force generated by the driving part 10 is avoided, the service life of the driving part 10 is prolonged, and the maintenance frequency is reduced.

The ball screw is driven to rotate by the rotation of the driving end of the servo motor 106, so that the screw nut connecting block 110 can move linearly. On one hand, the reciprocating motion of the lead screw nut connecting block is realized in a rotating mode, and the installation space of the driving piece 10 can be reduced, so that sufficient operation space is provided for overhauling and maintenance, and the subsequent overhauling and maintenance of the driving piece 10 are facilitated; on the other hand, the transmission form is simple and efficient, and the reduction of the transmission stage number can reduce the mechanical energy consumption in the transmission process, thereby ensuring the reduction of the electric energy consumption of the motor, saving the processing cost and improving the utilization rate of the electric energy.
As shown in fig. 5 to 6, a fifth embodiment of the present invention provides a frame adjusting mechanism, including: at least three drivers 10; each drive member 10 is adapted to engage the frame 134 to rotate and/or move the frame 134; and there is no direct linkage between the drivers 10.

In this embodiment, the driver 10 comprises at least two first drivers 102, at least one second driver 104. Specifically, the first driving member 102 is adapted to drive the screen frame 134 to rotate and move along the X-axis direction. That is to say, the first driving member 102 is used as a driving structure and can drive the screen frame 134 to rotate and move along the X-axis direction, when the position of the battery piece deviates in the X-axis direction, the position of the screen frame 134 in the X-axis direction is adjusted by the first driving member 102, so that the screen frame 134 moves in the X-axis direction, and thus the screen frame is aligned with the battery piece, the X-axis position of the screen frame is accurately adjusted, and the second driving member 104 is suitable for driving the screen frame 134 to move along the Y-axis direction through the linkage between the first driving members 102.

On the basis, the X-axis direction and the Y-axis direction are perpendicular to each other. That is, when the driving directions of the first driving element 102 and the second driving element 104 are perpendicular, the first driving element 102 and the second driving element 104 realize a linkage process. Specifically, as shown in fig. 19, fig. 20, fig. 21, fig. 23, and fig. 24, when the deviated position of the battery piece cannot be aligned by adjusting the screen frame 134 to move in the X-axis direction or the Y-axis direction alone, the screen frame is driven to rotate by the first driving member 102, so that the alignment process with the battery piece is ensured, the alignment with the position of the battery piece is further achieved, the alignment accuracy of the screen frame 134 is improved, and the printing quality of the battery piece is ensured. Of course, the driving sequence of the first driving element 102 driving the frame to move along the X axis and the second driving element 104 driving the frame to move along the Y axis and rotate the frame is not particularly limited, that is, the alignment process is within the protection scope of the present embodiment.
Specifically, as shown in fig. 7 to 13, the guide rail assembly 112 includes: a first rail member 114 for realizing the degree of freedom of the screen frame 134 in the X-axis direction or the Y-axis direction; a second rail member 116 for realizing the degree of freedom of the screen frame 134 in the X-axis direction or the Y-axis direction; and a cross roller bearing 118 having an outer race flange 1182 secured to the second rail member 116 and an inner race flange 1184 attached to the frame 134.
In this embodiment, as shown in fig. 7, 8, 12, and 13, the guide track assembly 112 includes a first guide track member 114, a second guide track member 116, and a cross roller bearing 118. That is, the first rail member 114 ensures the freedom of the screen frame 134 in the X-axis direction or the Y-axis direction, thereby allowing the screen frame 134 to move smoothly. The second rail member 116 ensures the freedom of the screen frame 134 in the X-axis direction or the Y-axis direction, so that the screen frame 134 can move smoothly in cooperation with the operation of the first rail member 114. The movement of the first rail member 114 and the second rail member 116 can be coordinated by the cross roller bearings 118 to complete the rotation of the screen frame 134.
Specifically, as shown in fig. 9 to 11, the first rail member 114 includes: a first guide rail 120 installed on the lead screw nut connection block 110 through a first guide rail connection member 130; a first slider 122 fixed on the base plate 128 and adapted to slide on the first rail 120; and the second rail member 116 includes: a second rail 124 perpendicular to the first rail 120 and fixed to an outer race flange 1182 of the cross roller bearing 118 by a second rail connector 132; and a second slider 126 fixed to the other side of the lead screw nut connecting block 110 and adapted to slide on the second guide rail 124.
In this embodiment, the first track member 114 is identical in construction to the second track member 116. But the second rail 124 is perpendicular to the first rail 120. That is, when the first rail member 114 moves under the driving of the driving element 10, the second driving element 104 is always perpendicular to the first rail member 114, so as to ensure the linkage between the first rail 120 and the second rail 124 and ensure that the screen frame 134 can complete the movement in the X-axis direction or the Y-axis direction.

The printing press of the present invention includes the frame adjusting mechanism 210 in any of the above embodiments. Therefore, when the printer performs the process of printing the battery piece, the position between the screen frame 134 and the battery piece is adjusted by the screen frame adjusting mechanism 210, which has all the beneficial effects of the screen frame adjusting mechanism 210, and is not described herein again.
In addition, the printing press includes a turntable mechanism 202 and a feeding mechanism 204. Specifically, the turntable mechanism 202 serves as a bearing structure for placing the battery pieces, and provides a printing screen frame for the battery pieces. The turntable mechanism 202 may be a structure in which a motor drives the turntable to rotate. The material conveying mechanism 204 may be a conveyor belt structure for feeding and discharging the battery pieces. For example: the number of stations on the rotary disc of the rotary disc mechanism is 4 and the stations are symmetrically arranged. The battery piece conveying mechanism 204 conveys the battery piece to a station at a feeding position; the turntable rotates 90 degrees, so that the battery piece rotates to the printing station, after the printing is finished, the turntable continues to rotate 90 degrees, so that the battery piece rotates to the discharging position, and the discharging is carried out through the conveying mechanism. In the whole process, the battery piece rotates 180 degrees in the same direction, so that the process that the battery piece corresponds to the adjusting mechanism is realized, and the battery piece can be smoothly and accurately printed.
In addition, the printer includes a detection mechanism 206 and a controller. Specifically, the detection mechanism 206 may be an infrared detection device, and is configured to detect the position of the battery cell on the turntable mechanism 202, so as to omit the manual positioning process by an observation method, shorten the printing time, and thus improve the printing efficiency. Specifically, the controller is electrically connected to the detection mechanism 206 and the frame adjusting mechanism 210, and can control the frame adjusting mechanism 210 to operate according to the detection result of the detection mechanism 206, so as to adjust the relative position between the frame and the battery piece. Therefore, on one hand, the information can be timely fed back to the detection mechanism 206 and the screen frame adjusting mechanism 210, and the degree of matching between the detection mechanism 206 and the screen frame adjusting mechanism 210 is increased, so that the printing quality is improved, and the processing time is shortened; on the other hand, the adjustment precision of the screen frame adjusting mechanism 210 is improved, so that the screen frame adjusting mechanism can accurately correspond to the positions of the battery pieces, and the yield of battery piece forming is improved.
In this embodiment, the frame adjusting mechanism 210 is disposed on the lifting mechanism 212 to adjust the height of the frame adjusting mechanism 210. Specifically, the lifting mechanism 212 is a cylinder or hydraulic cylinder mechanism, and is connected to the screen frame adjusting mechanism 210 through a mounting seat, and the lifting of the driving end of the cylinder or hydraulic cylinder drives the screen frame adjusting mechanism 210 to ascend or descend, so that the lifting of the screen frame adjusting mechanism 210 in the vertical direction is ensured, and the operation and printing of an operator are facilitated.

In this embodiment, the method of operating the printing press includes: the feeding process of the battery piece is completed through feeding, and then the position of the silk screen printing plate is guaranteed to correspond to the position of the battery piece through the matching of the adjusting screen frame and the position of the battery piece, so that the printing quality and the printing efficiency of the battery piece are improved, the printing process of the battery piece is performed afterwards, and finally the blanking of the battery piece is completed. The process of manual operation can be omitted through the process, and therefore the printing quality and the printing efficiency of the battery piece are improved.
In this embodiment, adjusting the frame to match the battery piece includes: the screen frame is rotated and/or moved through the screen frame adjusting mechanism in the embodiment, namely when the screen frame is moved, each first driving piece drives the screen frame to synchronously move in the same direction along the X-axis direction, and/or each second driving piece drives the screen frame to move along the Y-axis direction; when the screen frame is rotated, each first driving piece drives the screen frame to move asynchronously or reversely along the X-axis direction; and when the screen frame is rotated and moved, the first driving parts drive the screen frame to move asynchronously or reversely along the X-axis direction, and the second driving parts drive the screen frame to move along the Y-axis direction.

In this particular embodiment, as shown in FIG. 8, the first track member 114 is identical in construction to the second track member 116. But the second rail 124 is perpendicular to the first rail 120. That is, when the first rail member 114 moves under the driving of the driving element 10, the second driving element 104 is always perpendicular to the first rail member 114, so as to ensure the linkage between the first rail 120 and the second rail 124 and ensure that the screen frame 134 can complete the movement in the X-axis direction or the Y-axis direction.
As shown in fig. 1 to 5, a second embodiment of the present invention provides an adjusting mechanism, including a table; and the driving part 10 is positioned on the workbench and is suitable for driving the screen frame.
In this particular embodiment, the driver 10 comprises: at least one second drive member 104 and at least two first drive members 102; the second driving member 104 is adapted to be linked with the first driving member 102 to drive the frame to horizontally rotate and/or translate. In this embodiment, the second driving member 104 and the first driving member 102 are independently separated and located at the same height.
In this embodiment, the second drive member 104 and the first drive member 102 are identical in construction, except that the mounting locations are different, resulting in different drive directions for the frame. The driving direction of each second driving member 104 to the frame is the same, the driving direction of each first driving member 102 to the frame is the same, and the driving directions of the second driving members 104 and the first driving members 102 to the frame are perpendicular.
In this particular embodiment, the driver 10 comprises: a servo motor 106; a ball screw 108 positioned on the output shaft of the servo motor 106; a lead screw nut connecting block 110 positioned at the end of the ball screw 108; and the guide rail assemblies 112 are respectively connected with the lead screw nut connecting blocks 110.
In this embodiment, as shown in fig. 7, the guide rail assembly 112 includes: a first rail member 114 installed on the lead screw nut connection block 110; a second rail member 116 mounted on the first rail member 114 through a rail connector and horizontally perpendicular to the first rail member 114; the cross roller bearing 118 has its outer race flange 1182 secured to the second rail member 116 and its inner race flange 1184 secured to the frame 134. In this particular embodiment, as shown in FIG. 8, the outboard flange of the cross roller bearing 118 is secured to the second rail member 116 by a cross roller bearing connection. Of course, separate followers may be provided between the frames 134 to improve the stability of the table.
In this particular embodiment, the work table includes: the substrate 128; a driven plate located below the base plate 128 and adapted to move relative to the base plate 128; and the mounting plate is fastened below the driven plate, and the lower part of the mounting plate is suitable for mounting the screen frame. The mounting plate is detachably mounted below the driven plate.
In addition, referring to fig. 14 to 22, the movement process of each driving member for rotating and/or moving the frame is as follows:
as shown in fig. 14, 15 and 16, fig. 16 is set as a state where the frame is at the origin, and at this time, the distances between the lead screw nut connecting blocks on the two first driving members and the servo motor are equal, and the distances between the lead screw nut connecting blocks on the second driving members and the servo motor are equal.
When the screen frame is moved (translated) to the left along the Y axis relative to the original position, the lead screw nut connecting block on the second driving member moves toward the head end of the ball screw, as shown in fig. 16, the distance between the lead screw nut connecting block on the second driving member and the servo motor is small, and the distance between the lead screw nut connecting blocks on the two first driving members and the servo motor is basically unchanged.
Similarly, when the frame is to be moved upward along the X axis relative to the original position, the lead screw nut connecting blocks on the two first driving members move synchronously and simultaneously toward the head end of the ball screw, so that the distances between the lead screw nut connecting blocks on the two first driving members and the servo motor are synchronously reduced, and the distances between the lead screw nut connecting blocks on the second driving members and the servo motor are basically unchanged, which is not shown separately, but refer to fig. 17 and other views.
Referring to fig. 17 and 18, when the frame is desired to move along the X-axis and the Y-axis simultaneously and toward the upper right corner of fig. 17, the lead screw nut connecting blocks on the two first driving members simultaneously move toward the head end of the ball screw, and the lead screw nut connecting blocks on the second driving members move toward the tail end of the ball screw; as can be seen from fig. 17, the distance between the lead screw nut connecting block on the first driving member and the servo motor becomes smaller in synchronization, and the distance between the lead screw nut connecting block on the second driving member and the servo motor becomes larger.
Referring to fig. 19 to 20, when the frame is desired to rotate, the lead screw nut connecting block on the left first driving member moves toward the end of the ball screw, and the lead screw nut connecting block on the right first driving member moves toward the head end of the ball screw; as can be seen from fig. 18, the distance between the lead screw nut connecting block on the left first driving member and the servo motor becomes larger, and the distance between the lead screw nut connecting block on the right first driving member and the servo motor becomes smaller.
As shown in fig. 23, 24 and 25, when the frame is desired to be rotated and moved, the lead screw nut connecting block on the left first driving member moves toward the head end of the ball screw, and the lead screw nut connecting block on the right first driving member moves toward the tail end of the ball screw, and the lead screw nut connecting block on the second driving member moves toward the tail end of the ball screw; as can be seen from fig. 18, the distance between the lead screw nut connecting block on the left first driving member and the servo motor is increased, and the distance between the lead screw nut connecting block on the right first driving member and the servo motor is increased.
In the present application, when the screen frame rotates and/or moves, it is necessary to confirm according to the position matching relationship between the screen frame and the battery piece, so that the motion trajectories of the first driving element and the second driving element have various expression modes, and only some realizable modes are listed here to facilitate understanding of the technical solution of the present application, but not represent the actual driving process of each driving element in the production process.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
