Description

Technical Field

[0001] This application relates to the field of digital printing technology, and more particularly to a conveying mechanism and a printer. Background Technology

[0002] The QR codes on the circuit boards facilitate material traceability. For example, if a quality problem is found in a batch of components later, all circuit boards that used that batch of components can be quickly and accurately located. Furthermore, the QR codes enable process traceability, recording data from each step of the circuit board production process, which facilitates production management.

[0003] In related technologies, identical QR codes are typically printed on both sides of a circuit board for easy scanning by the system. The QR codes on both sides of the circuit board are printed separately by two printers, each printer printing different QR codes sequentially according to a count.

[0004] When manual intervention or printing process errors occur, such as when a circuit board malfunctions after being printed by the first printer and needs to be scrapped or is manually removed, the QR codes printed on both sides of the next circuit board may not match, causing the circuit board to need to have its QR codes reprinted or to be scrapped. Utility Model Content

[0005] The embodiments of this application aim to provide a conveying mechanism and a printer, so as to at least improve the problem of mismatched QR codes printed on both sides of a circuit board.

[0006] In order to solve the above-mentioned technical problems, the embodiments of this application adopt the following technical solutions: In a first aspect, embodiments of this application provide a conveying mechanism, which includes a conveying component and a shooting component. The conveying component includes a bracket, a conveying roller, and a first driving structure. The conveying roller is rotatably mounted on the bracket, and the first driving structure is mounted on the bracket and drivenly connected to the conveying roller. The first driving structure is used to drive the conveying roller to rotate in order to convey the workpiece to be printed. The shooting component includes a camera, a slide rail, and a slide base. The slide rail is mounted on the bracket and parallel to the conveying roller. The slide base is slidably connected to the slide rail, and the camera is mounted on the slide base. The camera is used to capture images of the printed workpiece.

[0007] In some embodiments, the shooting assembly includes a second crossbeam disposed on the bracket, and the slide rail is disposed on the second crossbeam.

[0008] In some embodiments, the support includes a first crossbeam and support columns, with at least two support columns spaced apart from the first crossbeam along its extension direction; the support columns are connected to a second crossbeam.

[0009] In some embodiments, the shooting assembly includes a second driving structure disposed on the bracket and drivenly connected to the slide block. The second driving structure is used to drive the slide block to slide along the slide rail.

[0010] In some embodiments, the second drive structure includes a second drive belt, a second driver, and at least two second pulleys. The second pulleys are rotatably mounted on the bracket, the second driver is mounted on the bracket, and the second drive belt is sleeved on at least two of the second pulleys. The second drive belt includes a tension section parallel to the slide rail and connected to the slide block. The second driver is drively connected to at least one second pulley to drive the slide block to slide along the slide rail.

[0011] In some embodiments, the imaging component includes a position sensor disposed on the bracket, the position sensor being used to detect the position of the slide relative to the slide rail during sliding motion.

[0012] In some embodiments, the shooting assembly includes a limiting member disposed on the bracket, the limiting member being used to abut against the slide block when the slide block slides relative to the slide rail to the endpoint of a safe range, so as to prevent the slide block from continuing to slide relative to the slide rail.

[0013] In some embodiments, the first drive structure includes a first drive belt, a first driver, and at least two first pulleys, the first pulleys being rotatably disposed on the bracket, the first driver being disposed on the bracket, and the first drive belt being sleeved on at least two of the first pulleys; the conveying roller is drivenly connected to at least one of the first pulleys, and the first driver is drivenly connected to at least one of the first pulleys to drive the conveying roller to rotate relative to the bracket; wherein, the conveying assembly includes at least two conveying rollers, each conveying roller being drivenly connected to at least one of the first pulleys; or, the first driver and the conveying roller are both located on the same side of the first drive belt.

[0014] Secondly, embodiments of this application provide a printer, the printer including a conveying mechanism as described in any embodiment of the first aspect.

[0015] The conveying mechanism and printer of this application embodiment are equipped with a camera in the conveying component, which can capture images of the workpiece to be printed during conveying. When the workpiece to be printed is a circuit board and a QR code has already been printed on one side, the camera can capture the QR code on the circuit board. When the workpiece to be printed needs to print a QR code again, it can be matched with the already printed QR code, thus improving the problem of mismatched QR codes printed on both sides of the circuit board.

[0025] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0026] Firstly, please refer to Figure 1 This application provides a conveying mechanism 100, which includes a conveying component 1 and a photographing component 2. The conveying component 1 is used to convey the workpiece to be printed, and the photographing component 2 is used to photograph the workpiece to be printed. Optionally, the workpiece to be printed is a circuit board.

[0027] For the aforementioned conveyor assembly 1, please refer to Figure 2The conveying assembly 1 includes a support 11, a conveying roller 12, and a first drive structure 13. The conveying roller 12 is rotatably mounted on the support 11, and the first drive structure 13 is mounted on the support 11 and connected to the conveying roller 12 in a driving connection. The first drive structure 13 drives the conveying roller 12 to rotate in order to convey the workpiece to be printed. The conveying roller 12 supports the workpiece to be printed, and by driving the conveying roller 12 to rotate around its own axis, it drives the workpiece to move, thus conveying the workpiece to be printed. Optionally, the conveying roller 12 is fitted with a rubber ring to increase the friction of the workpiece to be printed and reduce damage to the workpiece. Optionally, there are multiple conveying rollers 12, which are spaced apart along the conveying direction.

[0028] For the aforementioned bracket 11, please refer to Figure 2 The support frame 11 includes a first crossbeam 111 and support columns 112. At least two support columns 112 are spaced apart and connected to the first crossbeam 111 along its extension direction. The support columns 112 are connected to a second crossbeam 24. The support columns 112 are mounted on the work platform to fix the support frame 11 and support the first crossbeam 111. A conveyor roller 12 is mounted on the first crossbeam 111, providing a certain height to facilitate the placement of the imaging assembly 2 below it. Optionally, there are two support columns 112, each connected to one end of the first crossbeam 111. One end of each support column 112 is connected to the first crossbeam 111, and the other end is connected to the work platform.

[0029] For the first drive structure 13 mentioned above, please refer to Figure 2 The first drive structure 13 includes a first drive belt 131, a first driver 132, and at least two first pulleys 133. The first pulleys 133 are rotatably mounted on a bracket 11, the first driver 132 is mounted on the bracket 11, and the first drive belt 131 is sleeved on the at least two first pulleys 133. A conveyor roller 12 is driven by at least one first pulley 133, and the first driver 132 is also driven by at least one first pulley 133 to drive the conveyor roller 12 to rotate relative to the bracket 11. The first driver 132 drives the conveyor roller 12 to rotate via the first drive belt 131. When the conveyor roller 12 encounters significant resistance, such as when the printable part is jammed, the first drive belt 131 can slip off the first pulleys 133 to reduce damage to the conveyor roller 12 and the printable part. Optionally, the first driver 132 is a motor. Optionally, the first drive belt 131 is a belt. Optionally, one first pulley 133 is mounted on the output shaft of the first driver 132. Optionally, a first pulley 133 is mounted on the end of the conveyor roller 12.

[0030] In some embodiments, the conveying assembly 1 includes at least two conveying rollers 12, each conveying roller 12 being drively connected to at least one first pulley 133. For example, see [link to relevant documentation]. Figure 2Each conveyor roller 12 is provided with a first pulley 133, and the first transmission belt 131 passes through each first pulley 133 in sequence, so that at least two conveyor rollers 12 can be driven to rotate simultaneously and synchronously to achieve synchronous conveying of the workpiece to be printed.

[0031] In some embodiments, please refer to Figure 2 The first driver 132 and the conveying roller 12 are both located on the same side of the first transmission belt 131. The conveying roller 12 and the first driver 132 are connected by the first transmission belt 131, so that the first driver 132 can be set inside the support column 112 (i.e., between the two support columns 112), shortening the overall length of the conveying assembly 1.

[0032] For the aforementioned shooting component 2, please refer to Figure 1 and Figure 3 The imaging component 2 includes a camera 21 mounted on the bracket 11. The camera 21 is used to photograph the printed parts. The conveying component 1 also has a camera 21, which can photograph the parts to be printed during transport. When the part to be printed is a circuit board with a QR code already printed on one side, the camera can photograph and parse the QR code. When the part to be printed needs to have a QR code printed again, it can be matched with the already printed QR code, for example, matching identical or corresponding QR codes, thus ensuring that the QR codes on both sides of the circuit board match and improving the problem of mismatched QR codes printed on both sides of the circuit board.

[0033] In some embodiments, please refer to Figure 3 The imaging component 2 includes a slide rail 22 and a slide base 23. The slide rail 22 is mounted on the bracket 11 and is parallel to the conveyor roller 12. The slide base 23 is slidably connected to the slide rail 22, and the camera 21 is mounted on the slide base 23. The slide base 23 can be slidably connected to the slide rail 22 via a slider, allowing the slide base 23 to move relative to the conveyor component 1 in a direction parallel to the conveyor roller 12, enabling the camera 21 to scan the printable part back and forth. In different circuit boards, the QR code may be printed in different positions. By scanning the printable part back and forth with the camera 21, the problem of not being able to capture the QR code when it is not directly above the camera 21 can be improved.

[0034] In some embodiments, please refer to Figure 3The imaging component 2 includes a second crossbeam 24, which is mounted on the bracket 11, and a slide rail 22 is mounted on the second crossbeam 24. The two ends of the second crossbeam 24 are connected to the middle of two support columns 112. The slide rail 22 is mounted on the second crossbeam 24 along its length using multiple screws. The bracket 11 can only connect the slide rail 22 via two support columns 112, making the installation of the slide rail 22 unstable and prone to bending. However, by using the second crossbeam 24 as the mounting base for the slide rail 22, the installation stability of the slide rail 22 can be improved, bending of the slide rail 22 can be reduced, and the stability of the slide block 23 moving relative to the bracket 11 can be improved.

[0035] In some embodiments, please refer to Figure 1 and Figure 3 The imaging component 2 includes a second drive structure 25, which is mounted on the bracket 11 and is connected to the slide block 23. The second drive structure 25 drives the slide block 23 to slide along the slide rail 22. By driving the slide block 23 to move relative to the bracket 11 through the second drive structure 25, automatic scanning of the workpiece to be printed is achieved.

[0036] In some embodiments, please refer to Figure 4 The second drive structure 25 includes a second drive belt 251, a second driver 252, and at least two second pulleys 253. The second pulleys 253 are rotatably mounted on the bracket 11, the second driver 252 is mounted on the bracket 11, and the second drive belt 251 is sleeved on the at least two second pulleys 253. The second drive belt 251 includes a tension section 2511, which is parallel to the slide rail 22 and connected to the slide block 23. The second driver 252 is drively connected to at least one second pulley 253 to drive the slide block 23 to slide along the slide rail 22. The second driver 252 drives the slide block 23 to move via the second drive belt 251, thereby moving the camera 21. When the slide block 23 or the camera 21 encounters significant resistance, such as when the slide block 23 is jammed or the camera 21 hits an obstacle, the second drive belt 251 can slip between the second pulleys 253 to reduce damage to the slide block 23 and the camera 21. The tensioning section 2511 is the portion of the second drive belt 251 tensioned between two adjacent second pulleys 253. Optionally, the second driver 252 is a motor. Optionally, the second drive belt 251 is a belt. Optionally, one second pulley 253 is mounted on the output shaft of the second driver 252.

[0037] In some embodiments, please refer to Figure 3The imaging component 2 includes a position sensor 26, which is mounted on the bracket 11. The position sensor 26 is used to detect the position of the slide block 23 relative to the slide rail 22. Exemplarily, the position sensor 26 is a light sensor, having a light emitting end 261 and a light receiving end 262. The light emitting end 261 emits light to the light receiving end 262. The slide block 233 has a light-blocking plate 231. When the light-blocking plate 231 moves with the slide block 23 between the light emitting end 261 and the light receiving end 262, the light emitted from the light emitting end to the light receiving end 262 is blocked, thereby triggering the position sensor 26. The position of the position sensor 26 is configured such that when the slide block 23 moves to a specific position, such as the endpoint of a preset movement range of the slide block 23, the position sensor 26 is triggered by the light-blocking plate 231. Therefore, the triggering state of the position sensor 26 can be used to determine whether the slide block 23 has moved to a specific position, thus detecting the position of the slide block 23 relative to the slide rail 22. Optionally, the number of position sensors 26 is two. The two position sensors 26 are respectively used to trigger when the slide 23 moves to the two ends of the preset movement range, thereby improving the problem of the slide 23 moving beyond the preset movement range.

[0038] In some embodiments, please refer to Figure 3 The shooting component 2 includes a limiting member 27 disposed on the bracket 11. The limiting member 27 is used to abut against the slide 23 when the slide 23 slides relative to the slide rail 22 to the endpoint of a safe range, thereby preventing the slide 23 from continuing to slide relative to the slide rail 22. Exemplarily, the limiting member 27 is at least partially located on the movement path of the slide 23. When the slide 23 moves to the endpoint of the safe range, the limiting member 27 prevents the slide 23 from continuing to move in the previous direction, and the slide 23 can move in the opposite direction. Furthermore, the limiting member 27 can prevent the slide 23 from moving beyond the safe range, improving the problem of the slide 23 disengaging from the slide rail 22 when the position sensor 26 fails, and the problem of the slide 23 and camera 21 colliding with obstacles. It is understood that the preset movement range is within the safe range, that is, the two endpoints of the preset movement range are located between the two endpoints of the safe range.

[0039] Optionally, there are two limiting members 27. The two limiting members 27 are used to prevent the slide 23 from continuing to slide relative to the slide rail 22 when the slide 23 moves to the two ends of the safe range, thereby improving the problem of the slide 23 moving beyond the safe range. Optionally, the limiting member 27 is a screw, threadedly connected to the second crossbeam 24.

[0040] Secondly, embodiments of this application provide a printer, which includes a conveying mechanism 100. Using the conveying mechanism 100, when a workpiece needs to have a QR code reprinted, it can be paired with an already printed QR code, thus improving the problem of mismatched QR codes printed on both sides of the circuit board.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them; under the concept of this application, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of different aspects of this application as described above, which are not provided in detail for the sake of brevity; although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
