Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the description of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0032] The terms "comprises," "comprising," or any other variations thereof, are intended to cover a non-exclusive inclusion of the elements listed and may also include additional elements not expressly listed.

[0033] According to what the inventors have learned, current PCB printing equipment only supports the production of one type of board, and mainly produces single-sided boards (such as industry-standard boards and extra-large boards). It not only has single applicability and low production efficiency, but also has the problem of board falling due to the common use of vacuum suction cups to suck up the board surface for aerial transportation. In addition, when the vacuum suction cup repeatedly contacts the board surface, foreign matter on the board surface (such as floating oil and scum) will be stained by the vacuum suction cup, and the contaminated vacuum suction cup is extremely easy to contaminate the board surface of other boards.

[0034] In order to solve at least one of the above problems existing in the current PCB printing equipment, it is necessary to improve or optimize the structure of the auxiliary equipment or devices related to the PCB printing production.

[0035] Embodiment 1 See also Figure 1 , Figure 2The first embodiment of the present invention provides a distributing and conveying device for PCB printing, which is used to convey PCB. The distributing and conveying device 1 for PCB printing includes a frame 11, a horizontal conveying mechanism 12, a push mechanism 13, a translation mechanism 14 and a lifting and conveying mechanism 15, wherein the horizontal conveying mechanism 12, the push mechanism 13, the translation mechanism 14 and the lifting and conveying mechanism 15 are all installed on the frame 11, and the horizontal conveying mechanism 12 is used to convey the PCB along a first direction; the push mechanism 13 is used to push the PCB when the horizontal conveying mechanism 12 conveys the PCB to a preset position, so that the PCB rises from the horizontal conveying mechanism 12 along a second direction; the translation mechanism 14 is used to cooperate with the push mechanism 13, clamp the PCB lifted by the push mechanism 13, and move the PCB along a third direction to above the lifting and conveying mechanism 15; the lifting and conveying mechanism 15 is used to lift the PCB along the second direction and continue to convey the PCB along the first direction. It should be noted that the installation mentioned here refers to the installation and fixing of equipment, machinery or instruments by means of fixing elements (such as fastening bolts, fastening screws, etc.) or welding. The first direction, the second direction and the third direction are perpendicular to each other. Specifically, the first direction and the third direction refer to the horizontal direction, and the second direction refers to the vertical direction. The preset position refers to the horizontal position of the PCB waiting to be transported on the horizontal conveying mechanism 12 relative to the rack 11.

[0036] like Figure 3 As shown, the frame 11 is a rectangular parallelepiped frame structure, which includes a crossbeam 111, a longitudinal beam 112, a support beam 113 and a support seat 114, wherein one end of the crossbeam 111 and one end of the longitudinal beam 112 are fixedly connected in the horizontal direction, one end of the support beam 113 is fixedly connected to the connection between the crossbeam 111 and the longitudinal beam 112, and the support seat 114 is used to support the frame structure enclosed by the crossbeam 111, the longitudinal beam 112 and the support beam 113. Preferably, the crossbeam 111, the longitudinal beam 112 and the support beam 113 are perpendicular to each other, and there are multiple of them, which can not only ensure the structural performance of the frame 11, but also provide sufficient installation space for the horizontal conveying mechanism 12, the top mechanism 13, the translation mechanism 14 and the lifting conveying mechanism 15 installed on the frame 11.

[0037] In some implementations, there may be more than one support base 114 . In the first embodiment, there are six support bases 114 , and the height position in the vertical direction is adjustable, which is beneficial to ensure the stability of the rack 11 .

[0038] like Figure 4As shown, the horizontal conveying mechanism 12 includes a first servo module 121 and a first transmission module 122, wherein the first transmission module 122 is in transmission connection with the first servo module 121. Specifically, the first servo module 121 includes but is not limited to a first servo motor that controls the speed, direction and position of the motor by receiving a control signal to convert electrical energy into mechanical energy; the first transmission module 122 is a belt module, including a first driving wheel, a first driven wheel and a first conveyor belt, wherein the first driving wheel is connected to the output shaft of the first servo motor, the first driven wheel is fixed on the frame 11, and the first conveyor belt is connected between the first driving wheel and the first driven wheel. In this way, when the first servo module 121 is working, the first driving wheel rotates under the drive of the first servo motor, and at the same time drives the first conveyor belt and the first driven wheel to rotate, so that the PCB located on the first conveyor belt is transported to a preset position along the first direction.

[0039] In some embodiments, there may be multiple first transmission modules 122. In the first embodiment, there are twelve first transmission modules 122. The twelve first transmission modules 122 are arranged in parallel in the third direction for conveying large-size PCBs (such as 725mm×1245mm, 730mm×1245mm, etc.).

[0040] Furthermore, in order to solve the problems of single applicability and low production efficiency of the current PCB printing equipment, in some embodiments, the number of horizontal conveying mechanisms 12 can be multiple. In the first embodiment, the number of horizontal conveying mechanisms 12 is two, and the two horizontal conveying mechanisms 12 are arranged in parallel in the first direction. Preferably, the conveying directions of the two horizontal conveying mechanisms 12 are consistent, and one of the two horizontal conveying mechanisms 12 is close to the printing equipment in the first direction. It should be noted that the printing equipment mentioned here refers to a device used for printing text, graphics and solder mask layers in the PCB (printed circuit board) manufacturing process, which is usually composed of a print head, an ink cartridge, a motion mechanism and a control part, among which the print head adopts a high-precision nozzle to achieve fine printing; the ink cartridge has multiple colors of ink built in, which can be replaced as needed; the motion mechanism adopts precision lead screws, guide rails and other structures to achieve precise movement of the print head; the control part is responsible for controlling the movement of the print head and the ejection of ink. Compared with the existing technology that only supports the production of one type of board, the distribution and transmission device 1 disclosed in the present application is not only suitable for conveying large-size PCBs, but also has two horizontal conveying mechanisms 12. When conveying small-size PCBs (such as 610mm×711mm, 660mm×700mm, etc.), it can simultaneously convey two small-size PCBs to the printing equipment in a flat manner for post-printing processes. Compared with the existing technology that only conveys one small-size PCB, the present application is beneficial to doubling the production efficiency.

[0041] Furthermore, in order to avoid motion interference during the transportation of two small-sized PCBs, the distribution and transmission device 1 also includes a separation mechanism 16 for separating the two small-sized PCBs in the first direction, and the separation mechanism 16 is arranged between the two horizontal conveying mechanisms 12. In the first embodiment, the separation mechanism 16 includes a sixth servo module 161, a blocking rod seat 162 and a blocking rod 163, wherein the sixth servo module 161 is fixed to the frame 11 by a fixing element, one end of the blocking rod 163 is fixedly connected to the blocking rod seat 162, and is transmission-connected to the sixth servo module 161 through the blocking rod seat 162. Specifically, the sixth servo module 161 is a pneumatic module, such as a cylinder module. In some embodiments, there may be multiple separation mechanisms 16. In the first embodiment, there are four separation mechanisms 16, and the four separation mechanisms 16 are arranged in parallel along the third direction. In this way, viewed from the first direction, when the end of one of the two small-size PCBs is located on a horizontal conveying mechanism 12 close to the printing device, the sixth servo module 161 works. At this time, the sixth servo module 161 drives the blocking rod 163 to rise to a preset height position along the second direction, thereby separating the two small-size PCBs in the first direction and preventing the lateral spacing between the two small-size PCBs in the first direction from exceeding the requirement.

[0042] Furthermore, the distribution and transmission device 1 also includes a detection component 17 that is communicatively connected to the separation mechanism 16, and the detection component 17 includes at least one position sensor 171 for detecting the position of the PCB. In some embodiments, there may be multiple position sensors 171. In this embodiment, there are four position sensors 171. These four position sensors 171 are fixed on the frame 11 at a certain interval in the first direction or fixed on the frame 11 through an auxiliary bracket, and two of these four position sensors 171 are located on one side of the blocking rod 163 of the separation mechanism 16. In this way, when the distribution and transmission device 1 conveys two small-sized PCBs, since four position sensors 171 are arranged in the conveying direction of the PCBs, it is beneficial to convey the two small-sized PCBs to the preset positions on the two horizontal conveying mechanisms 12 respectively.

[0043] like Figure 5As shown, the push mechanism 13 includes a second servo module 131, a top wheel seat 132 and a top wheel 133, wherein the second servo module 131 is fixedly connected to the frame 11, and the top wheel 133 is rotatably connected to the top wheel seat 132, and is transmission-connected to the second servo module 131 through the top wheel seat 132. Specifically, the axial direction of the top wheel 133 is parallel to the first direction, and the second servo module 131 is also a pneumatic module, such as a cylinder module. In this way, when the horizontal conveying mechanism 12 conveys the PCB to a preset position along the first direction, the second servo module 131 works, and at this time, the top wheel 133, driven by the second servo module 131, first rises along the second direction and abuts against the bottom surface of the PCB, and then lifts up the PCB, so that the PCB continues to rise from the horizontal conveying mechanism 12 along the second direction to the preset position, that is, the PCB on the horizontal conveying mechanism 12 can be pushed to a preset height position through the push action of the push mechanism 13, so that the translation mechanism 14 can move the PCB.

[0044] like Figure 6 As shown, the translation mechanism 14 includes a third servo module 141, a second transmission module 142, a first guide module 143, a clamping rod seat 144 and a clamping rod 145, wherein the third servo module 141, the second transmission module 142 and the first guide module 143 are fixedly mounted on the frame 11, or fixedly mounted on the frame 11 through a bracket, the third servo module 141 and the second transmission module 142 are transmission-connected, one end of the clamping rod 145 is fixedly connected to the clamping rod seat 144, and is connected to the third servo module 141 through the clamping rod seat 144 and the second transmission module 142. Specifically, the third servo module 141 includes but is not limited to a second servo motor; the second transmission module 142 is a belt module, including a second driving wheel, a second driven wheel and a second conveyor belt, wherein the second driving wheel is connected to the output shaft of the second servo motor, the second driven wheel is fixed on the frame 11, and the second conveyor belt is connected between the second driving wheel and the second driven wheel; the first guide module 143 is a linear guide rail module, which is composed of accessories such as linear guide rails and sliders, and is used to ensure the moving direction of the clamping rod 145 in the third direction.

[0045] In some embodiments, the number of the third servo module 141, the second transmission module 142, the first guide module 143, the clamping rod seat 144 and the clamping rod 145 is more than one. In the first embodiment, the number of the third servo module 141 is two, the number of the second transmission module 142 is four, the number of the first guide module 143 is two, and the number of the clamping rod seat 144 and the number of the clamping rod 145 are both ten. It should be noted that five of the ten clamping rods 145 and the corresponding five clamping rod seats 144 are located on one side above the frame 11, and are connected to one of the two third servo modules 141 through two of the four second transmission modules 142. In this way, when the third servo module 141 is working, the second driving wheel rotates under the drive of the second servo motor, and at the same time drives the second conveyor belt and the second driven wheel to rotate, so that the clamping rod 145 moves along the third direction to clamp the opposite sides of the PCB lifted by the supporting mechanism 13, and moves the PCB along the third direction to above the lifting and conveying mechanism 15.

[0046] like Figure 7 , Figure 8 As shown, the lifting and conveying mechanism 15 includes a fourth servo module 151 and a lifting arm 153, wherein the lifting arm 153 is connected to the fourth servo module 151 in a transmission connection. Specifically, the fourth servo module 151 includes a third servo motor and a screw module connected to the third servo motor in a transmission connection, wherein the screw module is composed of a screw, a nut, a coupling, etc., and realizes linear motion by rotating the screw. In this way, when the PCB is located above the lifting arm 153 of the lifting and conveying mechanism 15, the fourth servo module 151 works. At this time, the lifting arm 153, driven by the fourth servo module 151, rises in the second direction and continues to rise to a preset height position after contacting the bottom surface of the PCB, so that the PCB can be disengaged from the top wheel 133 of the top mechanism 13, so that the lifting and conveying mechanism 15 can continue to convey the PCB in the first direction.

[0047] Furthermore, the lifting and conveying mechanism 15 also includes a fifth servo module 154 for transporting the lifting arm 153 and the fourth servo module 151 along the first direction, and a third transmission module 155 transmission-connected to the fifth servo module 154. Specifically, the fifth servo module 154 includes but is not limited to a fourth servo motor, and the third transmission module 155 is a belt module, including a third driving wheel, a third driven wheel and a third conveyor belt, wherein the third driving wheel is connected to the output shaft of the fourth servo motor, the third driven wheel is fixed on the frame 11, and the third conveyor belt is connected between the third driving wheel and the third driven wheel. In this way, when the PCB is out of contact with the top wheel 133 under the joint action of the fourth servo module 151 and the lifting arm 153, the fifth servo module 154 works. At this time, the fourth servo module 151, the lifting arm 153 and the PCB are driven by the fifth servo module 154 and the third transmission module 155, and move to the preset position along the first direction, that is, the PCB can be transported to the post-printing process where the printing equipment is located in a lifting manner. Compared with the existing technology of using a vacuum suction cup to suck the board surface for aerial transportation, this application is beneficial to solving the problem of PCB easy to fall and contamination.

[0048] Furthermore, the lifting and conveying mechanism 15 also includes a second guide module 152 and a third guide module 156. Specifically, the second guide module 152 and the third guide module 156 are both linear guide modules, which have the same structure as the first guide module 143 and are not repeated here. It should be noted that the second guide module 152 is installed between the fourth servo module 151 and the lifting arm 153 to ensure the movement direction of the lifting arm 153 in the second direction; the third guide module 156 is installed between the third transmission module 155 and the fourth servo module 151 to ensure the movement direction of the lifting arm 153 in the first direction. In some embodiments, the number of the second guide module 152 and the third guide module 156 can be multiple. In the first embodiment, the number of the second guide module 152 and the third guide module 156 is two.

[0049] Furthermore, in order to improve production efficiency, in some embodiments, there may be more than one lifting and conveying mechanism 15. In the first embodiment, there are two lifting and conveying mechanisms 15, and the two lifting and conveying mechanisms 15 are installed in parallel in the frame 11. It should be noted that the two lifting and conveying mechanisms 15 are used alternately, that is, when one of the two lifting and conveying mechanisms 15 is performing a conveying operation, the other of the two lifting and conveying mechanisms 15 is in a standby or initial state.

[0050] Embodiment 2 See also Fig. 9 , Fig.10 The second embodiment of the present invention provides a PCB printing production line, wherein: Fig. 9This is a schematic diagram of a double-sided printing production line for two small-size PCBs. Fig.10 It is a schematic diagram of a large-size PCB double-sided printing production line. The PCB printing production line includes two printing devices 2, two flipping devices 3 and two of the above-mentioned PCB printing distribution and transmission devices 1, wherein the two PCB printing distribution and transmission devices 1 are respectively installed at the feed end and the discharge end of the PCB printing production line, and one of the two PCB printing distribution and transmission devices 1 is connected to one of the two printing devices 2, and is connected to the other of the two printing devices 2 through one of the two printing devices 2 and the two flipping devices 3. It should be noted that the printing device 2 mentioned here includes two independent printing heads, and the two printing heads can be lifted and lowered in the second direction and moved in the third direction under the drive of the servo mechanism; the flipping device 3 mentioned here refers to a mechanical device or mechanism that can realize the flipping action of an object (such as a PCB, etc.), which includes a flipping machine and a guide positioning mechanism, and realizes the flipping of the object through a series of action processes.

[0051] Compared with the existing PCB printing production line that only supports the production of one type of board and uses a vacuum suction cup to absorb the board surface for aerial transportation, the PCB printing production line disclosed in the present application is not only suitable for the double-sided printing production of two small-size PCBs and a single large-size PCB, but also has the characteristics of high production efficiency. Since the PCB is transported from the front process to the back process in a lifting manner, it is also helpful to solve the problem of PCB easily falling and contamination.

[0052] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention.
