Description

Technical Field

[0001] The present application relates to the technical field of template printing systems, and more specifically, to a printing system and a method for controlling the printing system. Background Art

[0002] In the process of manufacturing surface mount printed circuit boards, a printer can be used to print solder paste onto the circuit board so that electronic components can be subsequently deposited onto the circuit board. The circuit board with a conductive surface is conveyed into the printer and correctly aligned with the apertures on the template of the printer from below through one or more small holes or marks (called "reference points") on the circuit board. Once the circuit board has been correctly aligned with the template in the printer, the circuit board will be raised to a height close to the template, and then the solder paste will be squeezed from the solder paste can onto the template. After the solder paste is dispensed onto the template, the scraper of the printer moves against the upper surface of the template to force the solder paste through the apertures on the template to the conductive surface of the circuit board.

[0003] For different types of circuit boards, the printing system sometimes needs to set up different devices to assist printing. For example, for some flexible circuit boards, the printing system needs to use a vacuum device to absorb and raise the circuit board from the bottom of the circuit board to facilitate circuit board printing. When printing other rigid circuit boards, the printing system does not need a vacuum device to absorb the circuit board, but supports and raises the circuit board through a track device.

[0035] Various specific embodiments of the present application will be described below with reference to the accompanying drawings that form a part of this specification. It should be understood that although terms indicating directions, such as "front", "rear", "upper", "lower", "left", "right", etc., are used in this application to describe various example structural parts and elements of the present application, these terms are used here only for the purpose of convenience of description and are determined based on the example orientations shown in the accompanying drawings. Since the embodiments disclosed in the present application can be set in different directions, these directional terms are only for illustration and should not be regarded as limitations. Where possible, the same or similar figure numbers used in this application refer to the same parts. In addition, the terms "stencil" and "template" may be used interchangeably herein, and both terms are used to describe a device in a stencil printer that defines a pattern to be printed on a substrate (i.e., a printed circuit board).

[0036] Figure 1A-Figure 1C The general structure of the printing system 100 is shown. Figure 1A is an external three-dimensional structural diagram of a printing system 100 according to an embodiment of the present application. Figure 1B The internal structure of the printing system 100 after removing the housing 101 is shown. Figure 1C FIG. 1 shows an exploded view of the printing system 100 after the housing 101 is omitted and the bracket 104 is further omitted. Figure 1A As shown, the printing system 100 includes a roughly square-shaped housing 101 and a control device 115. The control device 115 is configured to transport the circuit board to be printed from the entrance 102 of the printing system along the conveying direction 103 (i.e., the first direction or x direction) indicated by the arrow into the interior of the printing system 100, and then output it from the exit (blocked and not shown in the figure) after printing is completed.

[0037] Further Figure 1B-Figure 1C As shown, the printing system 100 also includes a bracket 104, and the bracket 104 is used to support the components of the printing system 100. The components of the printing system 100 include: a printing head 106, a pair of template brackets 107, a conveying mechanism 111 and a driving component 112. The conveying mechanism 111 is used to convey the plate 110 to be printed along the conveying direction 103. The driving component 112 is arranged below the conveying mechanism 111, and is used to drive the plate 110 to be printed to perform lifting and lowering movements along the up and down direction (i.e., the second direction or the z direction). The driving component 112 includes a driving motor 108. A pair of template brackets 107 are arranged above the conveying mechanism 111, wherein the template brackets 107 are used to support the template (not shown in the figure, see Figures 4A-5CThe template 442 in the figure has hollow holes on the template for defining the position of the solder paste printed on the board 110 to be printed. The printing head 106 is arranged above the template. The printing head 106 is used to force the solder paste to pass through the holes on the template to reach the designated position on the upper surface of the board 110 to be printed after dispensing the solder paste on the template by moving the scraper along the upper surface of the template.

[0038] It should be noted that the first direction x, the second direction z and the third direction y are substantially perpendicular to each other.

[0039] For the printing system 100, the general process of printing the plate 110 to be printed is as follows:

[0040] The board 110 to be printed has an alignment position and a printing position. The controller 115 first controls the conveying mechanism 111 to convey the board 110 to be printed from the entrance 102 to the alignment position below the template and aligned with the template. Then the controller 115 controls the driving component 112 to rise, and the driving component 112 drives the board 110 to be printed to rise to a position very close to the template or to a printing position where the upper surface of the board 110 contacts the lower surface of the template. Then the controller 115 controls the printing head 106 to print the solder paste through the holes on the template onto the board 110 to be printed. After printing is completed, the controller 115 controls the driving component 112 to descend, and the driving component 112 drives the board 110 to be printed to descend to a position away from the template. Finally, the controller 115 controls the conveying mechanism 111 to convey the board 110 to be printed to leave the printing system 100 from the exit. In this way, the printing process of a board 110 to be printed can be completed, waiting for the printing of the next board.

[0041] Depending on the type of board 110 to be printed, the more specific printing process of the printing system 100 may vary. For some rigid, large-size boards (see Figure 3A For the first plate 331 shown in FIG, the first plate 331 is directly mounted to the conveying mechanism 111, and the conveying mechanism 111 carries the first plate 331. The driving component 112 can directly drive the conveying mechanism 111 to raise the position of the first plate 331 to the printing position. Figure 3B For the second plate 332 shown in FIG. 1 , the second plate 332 needs to be mounted on the carrier 334 and installed on the conveying mechanism 111. In order to prevent the flexible second plate 332 from curling or warping during printing, the second plate 332 also needs to be vacuumed (see FIG. 1 ). Figure 5A-Figure 5C The vacuum device 441 shown in the figure absorbs and carries the second plate 332 from below. The driving component 112 drives the vacuum device 441 to push the second plate 332 out of the carrier 334 and lift it to the printing position.

[0042] It should be noted that, in this embodiment, the conveying mechanism 111 carrying and driving the first plate 331 or the vacuum device carrying and driving the second plate 332 refers to a device that carries and drives the corresponding plate after the corresponding plate reaches the alignment position. When the plate has not yet reached the alignment position, or when it leaves the alignment position after printing is completed, the plate is carried and conveyed by the conveying mechanism 111.

[0043] The printing system 100 further includes an identification device 116, which is used to identify the type of the board 110 to be printed (e.g., the first board 331 or the second board 332) and other parameters. In this embodiment, the identification device 116 is arranged at the entrance 102, so that the board 110 can be identified by the identification device 116 when it is transported into the entrance 102 through the transport mechanism 111, and the driving component 112 drives the board 110 to rise to the printing position after the board 110 is transported to the alignment position.

[0044] In this embodiment, the vacuum device is directly connected to the driving component 112 so that the driving component 112 drives the vacuum device to move. In order to prevent the vacuum device from interfering with or affecting the printing of the first plate 331 when printing the first plate 331, and to enable the vacuum device to eject the second plate 332 from the carrier 334 when printing the second plate 332, the printing system 100 further includes a clutch mechanism 120. The clutch mechanism 120 enables the driving component 112 and the conveying mechanism 111 to engage so that the driving component 112 can directly drive the conveying mechanism 111 to move, that is, the driving component 112 drives the vacuum device and the conveying mechanism 111 to move together. And the clutch mechanism 120 enables the driving component 112 and the conveying mechanism 111 to separate so that the driving component 112 can move relative to the conveying mechanism 111, that is, the driving component 112 only drives the vacuum device to move without driving the conveying mechanism 111 to move.

[0045] Figure 2A-2C Further eliminating Figure 1C The printing head 106 and the template support 107 in FIG. 1 show a more detailed internal structure of the printing system 100. Figure 2A FIG. 1 is a diagram showing the coordination structure of the conveying mechanism 111, the driving component 112 and the plate 110 to be printed. Figure 2B for Figure 2A Right view of Figure 2C for Figure 2A Exploded diagram of Figure 2A-2CAs shown, the conveying mechanism 111 includes a pair of conveying parts 219, and the board 110 to be printed is sandwiched between the pair of conveying parts 219 and conveyed along the x direction. The pair of conveying parts 219 are arranged oppositely and spaced in the third direction (i.e., the y direction), and can move closer to or away from each other to adapt to the different widths of the board 110 to be printed. In this embodiment, the board 110 to be printed is a first board 331, whose upper surface is roughly flush with the upper surface of the conveying part 219, so that when the driving component 112 drives the conveying mechanism 111 to move along the z direction until the conveying part 219 abuts against the lower surface of the template, the board 110 can be very close to the lower surface of the template or contact with the lower surface of the template.

[0046] The driving component 112 includes a support table 217, which is roughly square in shape. The driving motor 108 is used to connect to the bottom of the support table 217 to drive the support table 217 to move up or down along the z direction. The support table 217 is provided with a vacuum device mounting hole 218 at a position corresponding to between a pair of conveying parts 219 and below the template. The vacuum device mounting hole 218 is used to install a vacuum device so that the vacuum device can be located between the pair of conveying parts 219. When the conveying mechanism 111 conveys the plate 110 to be printed to the bottom of the template, the vacuum device is located below the plate 110 to be printed. A certain distance D is spaced between the upper surface of the support table 217 and the bottom of the pair of conveying parts 219. By setting this distance D, the support table 217 can have space for relative movement with the conveying part 219.

[0047] The printing system 100 further includes a frame 225, which is substantially in the shape of a square frame. The frame 225 includes a pair of first beams 226 disposed opposite to each other in the y direction and a pair of second beams 227 disposed opposite to each other in the x direction, and the pair of first beams 226 and the pair of second beams 227 are connected to each other to form the frame 225 in the shape of a square frame.

[0048] The pair of first beams 226 are fixedly connected to the support platform 217 of the driving component 112, for example, by bolts. In this embodiment, the four corners of the square support platform 217 are connected to both ends of each of the pair of first beams 226 in the y direction, so that the lifting movement of the support platform 217 in the z direction can drive the frame 225 to move in a balanced manner.

[0049] The pair of second beams 227 are connected to the conveying mechanism 111, for example, by fastening with bolts, etc. In this embodiment, both ends of each conveying portion 219 of the conveying mechanism 111 in the x direction are respectively connected to one of the pair of second beams 227, so that the pair of conveying portions 219 can maintain horizontal lifting and lowering movement, and the distance between the pair of conveying portions 219 in the y direction can be adjusted as needed.

[0050] The clutch mechanism 120 includes at least one correspondingly arranged clamp 221 and at least one guide rod 222, the clamp 221 is connected to the driving component 112, and the guide rod 222 is connected to the conveying mechanism 111. And each clamp 221 can clamp or release the corresponding guide rod 222, so that the driving component 112 and the conveying mechanism 111 can be engaged or separated. In this embodiment, the clutch mechanism 120 is connected between the first beam 226 and the second beam 227, and the clamp 221 is connected to the first beam 226, and the guide rod 222 is connected to the second beam 227. Thus, the clamp 221 clamps or releases the corresponding guide rod 222, which can make the first beam 226 and the second beam 227 engaged or separated, so that the driving component 112 is engaged or separated with the conveying mechanism 111. As an example, the clutch mechanism 120 includes four clamps 221 and four guide rods 222, and the four clamps 221 and the four guide rods 222 are respectively arranged at the four corners of the frame 225. For example, each clamp 221 is connected below the end of the first beam 226, the top of each guide rod 222 is connected to the end of the second beam 227, and the bottom of each guide rod 222 extends into the clamp 221 to be clamped or released by the clamp 221. As an example, the clamp 221 includes a cylinder, which can clamp the guide rod 222 when the cylinder is ventilated, and can release the guide rod 222 when the cylinder is de-aired. This arrangement ensures that the lifting and lowering movement of the drive component 112 and the conveying mechanism 111 in the z direction is approximately horizontal and balanced. In other embodiments, the clutch mechanism can also be set at other positions, other numbers, and can be set to other disengageable structures, as long as the drive component 112 and the conveying mechanism 111 can be engaged or separated.

[0051] Figure 3A and Figure 3B A schematic diagram of the structure of a board 110 to be printed is shown, wherein Figure 3A Schematic diagram showing the structure of the first plate 331, Figure 3B FIG. 3 is a schematic diagram showing the structure of the second plate 332. Figure 3A As shown, the first board 331 is a rigid circuit board, the upper surface of which is used for printing, and the two sides of which are respectively clamped on a pair of conveying parts 219 of the conveying device 111. The front end of the first board 331 in the conveying direction is provided with an identification code 335.

[0052] The second board 332 is a flexible circuit board. A plurality of second boards 332 are carried by a carrier 334 and enter the printing system for printing together. During the conveying process, both sides of the carrier 334 are clamped on a pair of conveying parts 219 of the conveying device 111. During the printing process, the vacuum device sequentially lifts the second boards 332 from the carrier 334 to complete the printing sequentially. The identification code 335 of the second board 332 is set at the front end of the carrier 334 in the conveying direction.

[0053] The identification code 335 of the first plate 331 and the second plate 332 can be identified by the identification device 116 to obtain parameter information. As an example, in addition to the type of identification plate in the identification code 335, various parameter data can also be included. For example, the number, size, thickness data of the plate, the attributes, size, position data of the template, the conveying speed data of the conveying mechanism, the printing head data such as the scraper pressure, printing speed, and scraper blade gap, the glue dispenser information, the glue dispensing number, the glue dispensing speed, the glue dispensing frequency, the glue application delay, the end delay and other glue dispensing data, the desizing monitoring information data, the demoulding speed, distance and other demoulding data. After receiving these parameters identified by the identification device 116, the control device 115 can control the operation of the printing system.

[0054] Figure 4A and Figure 4B FIG. 3 is a schematic diagram showing the coordination structure of various components of the printing system during the process of printing the first plate 331. Figure 4A The structure of each component of the printing system is shown when the first plate 331 is in the alignment position. Figure 4B FIG. 3 shows the structure of the various components of the printing system when the first plate 331 is in the printing position. Figure 4A As shown, the first plate 331 is clamped between a pair of conveying parts 219 of the conveying mechanism 111. When the conveying mechanism 111 conveys the first plate 331 to the alignment position, the vacuum device 441 is located below the first plate 331, and the conveying mechanism 111 is spaced a certain distance from the support table 217. The clutch mechanism 120 engages the driving component 112 and the conveying mechanism 111, that is, the clamp 221 clamps the guide rod 222. The control device 115 controls the driving component 112 to drive the conveying mechanism 111 and the vacuum device 441 to move upward along the z direction. Until the conveying mechanism 111 drives the carried first plate 331 to move to the position as shown in FIG. Figure 4B Printing position shown.

[0055] like Figure 4B As shown, the upper surface of the first plate 331 approaches or contacts the lower surface of the template 442, and the printing head can print solder paste to the first plate 331. After printing is completed, the driving component 112 drives the conveying mechanism 111 to move downward along the z direction to the alignment position. Then the conveying mechanism 111 continues to convey the first plate 331 to leave the printing system 100. During this process, the vacuum device 441 rises or falls synchronously with the support table 217 of the driving component 112 and the conveying mechanism 111, so the vacuum device 441 does not interfere with the printing of the first plate 331, but always remains below the first plate 331.

[0056] Figure 5A-Figure 5C FIG. 3 is a schematic diagram showing the coordination structure of various components of the printing system during the printing of the second plate 332. Figure 5AThe structure of the various components of the printing system is shown when the second plate 332 is in the aligned position. Figure 5B The structure of each component of the printing system is shown when the second plate 332 is in the middle position. Figure 5C FIG. 3 shows the structure of the components of the printing system when the second plate 332 is in the printing position. Figure 5A As shown, the second plate 332 is clamped between a pair of conveying parts 219 of the conveying mechanism 111 by the carrier 334. When the conveying mechanism 111 conveys the second plate 332 to the alignment position, the vacuum device 441 is located below the first plate 331, and the conveying mechanism 111 is spaced a certain distance from the support table 217. The clutch mechanism 120 separates the driving component 112 and the conveying mechanism 111, that is, the clamp 221 releases the guide rod 222. The control device 115 controls the driving component 112 to move relative to the conveying mechanism 111, that is, drives the vacuum device 441 to move upward along the z direction, but the conveying mechanism 111 does not move. Until the vacuum device 441 drives the carried second plate 332 to move to the position as shown in the figure. Figure 5B The middle position shown.

[0057] like Figure 5B As shown, the support platform 217 rises upward relative to the conveying mechanism 111, so that the distance D between the support platform 217 and the conveying portion 219 is reduced. The vacuum device 441 is driven by the driving component 112 to move upward to push the second plate 332 out of the carrier 334. At this time, the control device 115 can turn on the vacuum device 441 so that the vacuum device 441 adsorbs the second plate 332. Then the clutch mechanism 120 engages the driving component 112 and the conveying mechanism 111, that is, the clamp 221 clamps the guide rod 222. The control device 115 controls the driving component 112 to drive the conveying mechanism 111 and the vacuum device 441 to rise and move upward along the z direction. Until the vacuum device 441 drives the carried second plate 332 to move to the position as shown in the figure. Figure 5C Printing position shown.

[0058] like Figure 5C As shown, the upper surface of the second plate 332 is close to or in contact with the lower surface of the template 442, and the printing head can print solder paste on the second plate 332. After printing is completed, the driving component 112 first drives the vacuum device 441 and the conveying mechanism 111 to move downward along the z direction to the middle position, and then the clamp 221 releases the guide rod 222, so that the vacuum device 441 and the support table 217 continue to descend to the alignment position relative to the conveying mechanism 111. Then the conveying mechanism 111 continues to convey the next second plate 332 on the carrier 334 to the alignment position. After all the second plates 332 on the carrier 334 are printed, the conveying mechanism 111 conveys the carrier 334 to leave the printing system 100.

[0059] Thus, the driving component 112 can complete the printing of the first plate 331 or the second plate 332 by driving the conveying mechanism 111 and the vacuum device 441 at the same time, or by driving only the vacuum device 441 .

[0060] Figure 6 1 shows a block diagram of the control device 115. Figure 6 As shown, the control device 115 includes a bus 671, a processor 672, an input interface 673, an output interface 674, and a memory 675 having a control program 676. The various components in the control device 115, including the processor 672, the input interface 673, the output interface 674, and the memory 675, are communicatively connected to the bus 671, so that the processor 672 can control the operation of the input interface 673, the output interface 674, and the memory 675. Specifically, the memory 675 is used to store programs, instructions, and data, and the processor 672 reads programs, instructions, and data from the memory 675, and can write data to the memory 675. By executing the programs and instructions read from the memory 675, the processor 672 controls the operation of the input interface 673 and the output interface 674.

[0061] like Figure 6 As shown, the input interface 673 is connected to the recognition device 116 through the connection 677 to receive various parameters of the identification code 335 recognized by the recognition device 116, and store these parameters in the memory 675. The output interface 674 is connected to the drive component 112 and the clutch mechanism 120 through the connection 678. By executing the program 676 in the memory 675, the control device 115 controls the clutch mechanism 120 to make the drive component 112 and the conveying mechanism 111 move together or relatively, and controls the drive component 112 to make the conveying mechanism 111 or the vacuum device 441 drive the corresponding first plate 331 or second plate 332 carried by it to move from the alignment position to the printing position. In addition, the control device 115 is also connected to the print head 106 to control the printing process of the print head 106 according to the recognized parameters.

[0062] Figure 7A-7C FIG. 1 is a partial flow chart showing a control method of a printing system. Figure 7A-7C As shown, at step 761, various parameter information of the first board or the second board is identified.

[0063] If the board to be printed is the first board, step 762 is performed.

[0064] At step 762 , the first plate is transported to an alignment position, and then step 763 is performed.

[0065] At step 763 , the transport mechanism drives the first plate to the printing position, and then step 764 is performed.

[0066] At step 764, a first board is printed.

[0067] After printing is completed, the conveying mechanism drives the first plate to the alignment position and then conveys the first plate away from the printing system.

[0068] If the board to be printed is the second board, step 765 is performed.

[0069] At step 765 , the second plate is transported to the alignment position and then step 766 is performed.

[0070] At step 766 , the vacuum device drives the second plate to the printing position and then step 767 is performed.

[0071] At step 767, a second board is printed.

[0072] After printing is completed, the vacuum device drives the second plate to the alignment position, and then transports the next second plate to the alignment position, until all the second plates on the carrier are printed and transported out of the printing system.

[0073] The steps performed at step 763 include:

[0074] At step 781 , the clutch mechanism is engaged to clamp the guide rod, and then step 782 is executed.

[0075] At step 782, the driving component drives the conveying mechanism and the vacuum device to move together, so that the conveying mechanism drives the first plate to move to the printing position.

[0076] And wherein the steps performed at step 766 include:

[0077] At step 783 , the clutch mechanism is disengaged, the clamp releases the guide rod, and then step 784 is executed.

[0078] At step 784 , the driving component moves relative to the conveying mechanism and drives the vacuum device to move, so that the vacuum device drives the second plate to move to the middle position, and then step 785 is executed.

[0079] At step 785 , the clutch mechanism engages, clamps the guide rod, and then step 786 is executed.

[0080] At step 786, the driving component drives the conveying mechanism and the vacuum device to move together, so that the vacuum device drives the second plate to move to the printing position.

[0081] In some printing systems, different types of boards need to be printed with the same device. When switching the process of printing different types of boards, it is also necessary to install or remove the vacuum device according to the different boards. Frequent installation or removal may cause damage to the template, and the manual operation process is complicated.

[0082] The present application is directed to different types of boards, and printing of different types of boards is accomplished by controlling the bearing and driving components of the boards without disassembling or removing the vacuum device.

[0083] Furthermore, the identification code of the board of the present application may carry parameter data of various boards and printing processes, so that the control device can control the printing process according to these parameter data.
