Description

Technical Field

[0001] The utility model relates to an inkjet printing device, in particular to a mini circuit board inkjet printing device. Background Art

[0002] During the printing process, the print head sprays ink onto the PCB board through inkjet technology to form the required characters and lines. The printing process is divided into three steps: inkjet, move and solidify. First, the print head sprays ink according to the predetermined pattern; then, the PCB board is moved through the mechanical transmission part to achieve printing in different areas; finally, the ink is solidified by the curing equipment to form a stable line.

[0003] A Chinese patent with application number CN202022603893.2 discloses a circuit board inkjet printing device, including a printing area integrated system, a disc rotating system, a rotation accuracy feedback control system and a post-processing area integrated system. The disc rotating system is mainly composed of a base, a disc rotating device, an angle control device and a working platform. The working platform can be divided into more than two working areas. Any working area can be switched to the corresponding printing area integrated system or post-processing area integrated system by rotation to perform printing or post-processing operations. This device subverts the traditional forward and backward moving work surface. By adopting the method of rotating and moving the work surface, the printing area and the post-processing area can be quickly converted, and post-processing can be performed simultaneously during the printing process. The rotation accuracy feedback control system can realize the determination, feedback and correction control of the accuracy of the rotation angle of the working platform, so as to achieve the goal of precise positioning during multiple / layer printing processes. However, in actual use, the circuit board needs to be printed on both sides. After printing one side, it needs to be turned over to print the other side. The device can only rely on manual turning of the board, which is inefficient. In addition, since the ink is not dry and solidified after printing, human contact may cause the printed pattern to be damaged, affecting the printing effect. Utility Model Content

[0004] In order to overcome the problem that when a circuit board needs to be printed on both sides, it needs to be turned over to print the other side after printing on one side. The existing device can only rely on manual turning over, which is inefficient. In addition, since the ink has not dried and solidified after printing, human contact may cause the printed pattern to be damaged, affecting the printing effect. The purpose is to provide a mini circuit board inkjet printing device that does not require manual turning over of the circuit board, saves manpower, reduces the damage caused by human contact to the undried ink after printing, and reduces the output of defective products during processing.

[0005] The technical solution is: a mini circuit board inkjet printing device, including a bracket, an electric slide rail, a screen, a slider, a plate placing device, a rotating cylinder, a connecting frame, a transmission group and a printer. The front and rear sides of the upper part of the bracket are connected with electric slide rails, and sliders are slidably provided on the electric slide rails. Plate placing devices are rotatably provided on the upper part of the sliders. The two plate placing devices are symmetrically arranged front and back. A screen is installed on the right part of the rear electric slide rail, and a rotating cylinder is installed on the upper part of the slider. The rotating blocks of the rotating cylinder are fixedly connected to the rotating frame on the slider on the same side. Connecting frames are welded on the front and rear sides of the upper part of the bracket. A transmission group is installed between the upper parts of the connecting frames. The transmission group consists of a mounting plate, a synchronous belt group and a motor that provides power to the synchronous belt. The right part of the transmission group is slidably provided with a printer.

[0006] Furthermore, it also includes a pallet, a support plate, a clamping block, a top block and a flexible rod. The sliders are all provided with sliding grooves, and the pallet is slidably arranged between the sliding grooves of the sliders. The front and rear sides of the left part of the pallet are two long strip plates. The right part of the pallet is fixedly connected with a clamping block. Two support plates are fixedly arranged between the electric slide rails. The top block is fixedly connected to the support plate on the left side, and two flexible rods are connected to the support plate on the right side.

[0007] Furthermore, it also includes a shell and a transparent plate. The shell is welded to the outside of the bracket, and a plurality of transparent plates are arranged on the front and rear sides of the shell.

[0008] Furthermore, it also includes partition one, partition two and a UV curing lamp. Partition one and partition two are fixedly connected on the right side of shell one. Partition one and partition two separate the shell into curing stations. Two UV curing lamps are fixedly connected on the upper and lower sides between partition one and partition two.

[0009] Furthermore, the width of the card slots between the plates is consistent with the thickness of the circuit board to be printed.

[0010] The beneficial effect is that the utility model drives the plate to rotate and turn over after printing on one side through a rotating cylinder, and there is no need to manually turn over the circuit board, which saves manpower and reduces the damage caused by human contact to the undried ink after printing, thereby reducing the occurrence of defective products during processing.

[0011] The utility model supports the circuit board by the support plate, so as to prevent the unsupported area of ​​the circuit board between the plates from bending downward under its own weight, which would affect the overall effect of printing.

[0012] The utility model can dry and solidify the printed ink in time after the printing is completed, and there is no need to perform subsequent solidification process through other devices, thereby shortening the processing flow and improving production efficiency.

The front and rear sides of the upper part of the bracket 1 are connected to the electric slide rail 2. The electric slide rail 2 is composed of a driving motor and a screw rod, which can drive the object to move linearly at a variable speed. The electric slide rail 2 is slidably provided with a slider 3, and the upper part of the slider 3 is rotatably provided with a plate placement 4. The plate placement 4 has a card slot for placing the circuit board. The two plate placements 4 are symmetrically arranged front and back. The right part of the rear electric slide rail 2 is installed with a screen 21. The screen 21 is connected to each power component on the device through a signal, and these devices can be controlled through the screen 21. The upper part of the slider 3 is installed with a rotating device that can drive the connected object to rotate at an angle Cylinder 41, the rotating block of the rotating cylinder 41 is fixedly connected to the rotating frame on the slider 3 on the same side. After one side of the circuit board is printed, the circuit board on the plate 4 is flipped 180 degrees to achieve automatic flipping. Connecting frames 5 are welded on both the front and rear sides of the upper part of the bracket 1. A transmission group 51 is installed between the upper parts of the connecting frames 5. The transmission group 51 consists of a mounting plate, a group of synchronous belt groups and a motor that provides power to the synchronous belt. A printer 6 is slidably provided on the right part of the transmission group 51. The printer 6 is fixedly connected to the synchronous belt of the transmission group 51 and moves forward and backward with the rotation of the synchronous belt. The printer 6 consists of a print head, an ink cartridge, a print control board, a mechanical transmission part and a power supply. Under the control of the preset program on the screen 21, the circuit board can be automatically positioned and printed.

[0022] Initially, the printer 6 is at the front position of the transmission group 51, and the slider 3 is located at the right position of the electric slide rail 2. The circuit board to be printed is placed flat between the card slots of the two placement plates 4, and the card slots clamp the two sides of the circuit board. At this time, the circuit board is parallel to the ground, and then the electric slide rail 2 is started through the screen 21, and the slider 3 and the circuit board are driven to move to the left through the electric slide rail 2. When the circuit board moves to the position on the same line before and after the nozzle of the printer 6, the electric slide rail 2 is controlled to stop moving the slider 3, and then the synchronous belt group is driven to rotate by the motor on the transmission group 51, and the printer 6 connected to the synchronous belt group is driven to move backward. When the printer 6 moves backward, the nozzle of the printer 6 will pass directly above the circuit board. Before the position of the printer 6 moves to a position close to the front side of the circuit board, the printer 6 is started. While the printer 6 moves backward, the nozzle sprays printing ink onto the circuit board through the printing program pre-set in the screen 21. The circuit board stopped at the bottom is subjected to printing processing. When the nozzle of the printer 6 moves and passes over the rear side of the circuit board, the printing is stopped and the transmission group 51 is controlled to stop working at the same time. The printer 6 stops at the rear position of the transmission group 51. Then, the electric slide rail 2 is controlled to continue to move the slider 3 backward, driving the circuit board to slide to the left. When the circuit board moves to the left position of the electric slide rail 2, the slider 3 is stopped. Then, the rotating cylinder 41 is controlled to drive the plate 4 to rotate 180 degrees. The printed side will rotate to the lower side with the plate 4, and the unprinted side will rotate from the bottom to the top. Then, the electric slide rail 2 is controlled to drive the slider 3 to move horizontally to the right. When the slider 3 moves to the bottom of the printer 6, it stops. The transmission group 51 is controlled to drive the printer 6 to move forward and print, and continue to print on the upward side of the circuit board. When the printing is completed, the slider 3 is controlled to move right to the right feeding position of the electric slide rail 2, and the circuit board printed on both sides is taken away to complete the printing.

[0023] Example 2: Based on Example 1, refer to Figure 2 , Figure 4 and Figure 5, also includes a support plate 9, a support plate 90, a block 91, a top block 92 and a flexible rod 93. The slider 3 is provided with a slide groove 31, and a support plate 9 is slidably arranged between the slide grooves 31 of the slider 3. The friction between the slide groove 31 and the support plate 9 is large. When the slider 3 moves, the support plate 9 will be dragged to move. The right part of the support plate 9 is set as a plate surface, and an edge of the lower side of the left side of the plate surface of the support plate has an inverted arc angle. The left front and rear sides of the plate surface of the support plate 9 are two strip-shaped long plates. The right part of the support plate 9 is fixedly connected with a block 91, which will push the electric slide rail 2 fixedly provided with a There are two support plates 90, and a top block 92 is fixedly connected to the left support plate 90. When the slider 3 moves to the left on the electric slide rail 2, the support plate 9 will contact the top block and be supported by the top block 92. When the slider 3 continues to move to the left, the support plate 9 will temporarily remain in the supported area. Two flexible rods 93 are connected to the right support plate 90. The flexible rods 93 will bend when subjected to force, and the bending stress of the flexible rods 93 will be greater than the friction between the slide groove 31 and the support plate 9. When the flexible rods 93 support the support plate 9, the slider 3 continues to move, and the support plate 9 will be temporarily retained in the supported area.

[0024] See also Figure 1-2 , also includes a shell 7 and a transparent plate 71. The shell 7 for protecting the device is welded on the outside of the bracket 1. A plurality of transparent plates 71 are arranged on the front and rear sides of the shell 7. The transparent plates 71 are used for people to observe the working state inside the shell when the device is working.

[0025] See also Figure 2 , and also includes a partition 1 8, a partition 2 81 and a UV curing lamp 82. The partition 1 8 and the partition 2 81 are fixedly connected on the right side of the shell 7. The partition 1 8 and the partition 2 81 separate the shell 7 into a curing station. Two UV curing lamps 82 are fixedly connected on the upper and lower sides between the partition 1 8 and the partition 2 81. The UV curing lamp 82 will emit light with a higher temperature. When it is irradiated on the printed circuit board, it will accelerate the drying and curing process of the printed pattern.

[0026] A shell 7 is installed on the outside of the bracket 1 to protect the entire printing device, which effectively protects the device. When the board is placed on the plate 4, the lower side of the circuit board will contact the top side of the support plate 9, and the circuit board is lifted by the support plate 9 to prevent the unsupported area of ​​the circuit board between the plate 4 from bending downward under its own weight, affecting the overall effect of printing. When the slider 3 moves, it will drive the support plate 9 to move. When the circuit board is printed on the upper side and needs to be moved to the left part of the electric slide rail 2 for turning over, in this process, the arc edge of the lower left side of the upper plate surface of the support plate 9 moving to the left will contact the soft The upper end of the flexible rod 93 contacts the upper end of the flexible rod 93, and driven by the friction between the edge of the arc surface and the slider 3 and the support plate 9, the flexible rod 93 will bend to the left along with the guidance of the edge of the arc surface and slide in contact with the bottom side of the support plate 9. When the left side of the board surface of the support plate 9 moves with the slider 3 to contact with the top block 92, the top block 92 will hold the support plate 9. At this time, the flexible rod 93 will be in contact with the right side of the support plate 9, and the slider 3 drives the circuit board to continue to move to the left, and the support plate 9 is held up. However, the slide groove 31 of the slider 3 will continue to slide in contact with the strip plate on the support plate 9 during this process and will not disengage. When the slider 3 moves to the left position of the strip plate on the support plate 9, the rotation control starts. The rotating cylinder 41 drives the circuit board to rotate. At this stage, the rotation of the circuit board will not be interfered by the board surface of the support plate 9. After the rotation is completed, the slider 3 starts to move to the right. The right side of the support plate 9 is not chamfered in an arc shape. The flexible rod 93 will support the right side of the support plate 9. When the slider 3 moves, the support plate 9 is not driven to move. When the slider 3 moves to contact with the block 91, the block 91 will support the slider 3. At this time, the force driven by the electric slide rail 2 to push the slider 3 will be greater than the bending stress of the flexible rod 93. The flexible rod 93 is bent by the thrust and, under the action of the movement of the slider 3, it will slide in contact with the bottom side of the support plate 9. The flexible rod 93 is in contact with the support plate. 9 moves away and returns to an unbent state. When both sides of the circuit board are sprayed, the electric slide rail 2 drives the circuit board to move to the area between the partition 1 8 and the partition 2 81. After entering the area, the control slider 3 stops moving and starts the UV curing lamp 82, which irradiates high-temperature light to irradiate the upper and lower sides of the circuit board to accelerate the curing of the ink after printing. When the ink is cured, turn off the UV curing lamp 82, and control the slider 3 to move the circuit board to the loading area outside the shell 7 for unloading. During the printing and material transfer process, people can observe the processing status through the transparent plate 71 on the shell 7.

[0027] In a preferred embodiment: the width between the upper and lower parts of the card slots between the plate plates 4 is consistent with the thickness of the circuit board to be printed. After placing the circuit board on the slots, the card slots will clamp the circuit board to prevent it from detaching from the plate plates 4 when flipped.
