Description

Technical Field

[0001] This utility model relates to the field of improved design technology of front and back flipping device, and in particular to a flipping conveyor device for flipping the front and back of a board. Background Technology

[0002] For boards requiring double-sided laser marking, two laser machines can be used, one mounted on top and one on the bottom of the board, to mark simultaneously, but this doubles the cost. Alternatively, the front can be marked first, followed by the back. For example, when marking one side of a board held by a belt, the board is conveyed out by a belt on a clamping plate. A worker flips the board, places it on a transport track, and then it's conveyed back to the clamping plate, where a belt holds it in place. The laser marking machine then marks the other side. Manual flipping is less efficient. Automatic flipping devices are also available, but these have complex structures and may result in inconsistent levelness after flipping.

[0003] In the prior art, patent CN215919424U discloses a flipping device for a laser marking machine, including two parallel mounting plates installed on the main body of the laser marking machine. Each mounting plate is rotatably connected to a clamping plate. A rotating rod is connected to the side of the clamping plate facing the mounting plate, and the rotating rod is rotatably connected to the mounting plate. A flipping mechanism for driving the clamping plate to flip is also provided on the mounting plate. The flipping mechanism includes a transmission component mounted on each mounting plate, comprising a main wheel, a driven wheel, and a synchronous belt. The main wheel and the driven wheel are rotatably connected to the mounting plate, and the driven wheel is connected to the end of the rotating rod away from the clamping plate. The main wheel and the driven wheel are connected by a synchronous belt. The flipping mechanism also includes a drive component for driving the main wheel to rotate, and the drive component is mounted on the mounting plate. This application improves the marking efficiency of laser marking machines for double-sided marking on PCB boards.

[0004] Patent CN218426331U discloses an automatic flipping device for a laser double-sided coding machine, comprising a flipping device body, a fixed conveyor track and a movable conveyor track disposed on the flipping device body and cooperating with each other to transport the product, both of which include a mounting plate; a conveyor channel located on one side of the mounting plate and composed of a conveyor belt; clamping plates disposed on both sides of the conveyor channel and slidably connected to the mounting plate; clamping plate positioning blocks disposed on both sides of the conveyor channel and fixedly connected to the mounting plate, the clamping plates being located between the clamping plate positioning blocks and the conveyor channel; a drive motor fixed on the other side of the mounting plate for driving the conveyor belt to rotate; and a clamping plate driving component fixed on the other side of the mounting plate for driving the clamping plates to slide and position and clamp the product; the clamping plate positioning blocks are used to position the clamping plates, and when the working surface of the product is at a predetermined height, the top clamping plate abuts against the corresponding clamping plate positioning block to ensure that the height of the working surface of the product is consistent before and after flipping.

[0005] In order to solve one of the above problems, this application provides a flipping conveyor for flipping the front and back sides of a sheet material. Utility Model Content

[0027] Example 1

[0028] Reference Figure 1-4 As shown, this utility model discloses a flipping conveyor device for flipping the front and back sides of a sheet metal, comprising a track width adjustment mechanism 1 and a flipping mechanism 5. The track width adjustment mechanism 1 includes a movable track structure 2 and a fixed track structure 3 with identical structures. The movable track structure 2 and the fixed track structure 3 are arranged opposite to each other, and the distance between them is adjusted by the track width adjustment mechanism 1 to convey sheets of different sizes. The installation position of the fixed track structure 3 remains unchanged, while the movable track structure 2 can move closer to or further away from the fixed track structure 3 along a linear guide rail under the drive of a screw mechanism, thereby adjusting the distance between the movable track structure 2 and the fixed track structure 3 to meet the requirements of conveying different sheets of metal, such as metal sheets or circuit boards.

[0029] Taking fixed track structure 3 as an example, a detailed explanation will be provided, combined with... Figure 2It is understood that the fixed track structure 3 includes a second mounting plate 35, a second flip lock assembly 34, and a second flip track 31. The second flip lock assembly 34 includes a sixth motor 341 and a sixth gear 342 driven by the sixth motor 341 after its speed is reduced. The sixth motor 341 is horizontally adjustable and mounted on the second mounting plate 35 to adjust the horizontal position of the sixth gear 342. The second flip track 31 is rotatably mounted on the second mounting plate 35 via a third synchronous belt drive assembly 53. The third synchronous belt drive assembly 53 is connected to a drive shaft 54 ​​and driven by a flipping mechanism 5. The flipping mechanism 5 drives the second flip track 31 to rotate via the third synchronous belt drive assembly 53. The second flip track 31 includes a second flip plate 311 and a third gear 312, a fourth gear 313, a second upper adjusting plate 317, a second lower adjusting plate 318, a third belt 316, a fourth belt 315, and multiple pulleys mounted on the second flip plate 311. The third belt 316 transmission assembly is formed by the third belt 316 and the fourth belt 315 and multiple pulleys. The third gear 312 and one corresponding pulley of the third belt 316 are coaxially connected, and the fourth gear 313 and one corresponding pulley of the fourth belt 315 are coaxially connected. The third gear 312 or the fourth gear 313 meshes with the sixth gear 342. Only one of the third gear 312 and the fourth gear 313 is engaged and the other is not engaged. That is, the third belt 316 transmission assembly or the fourth belt 315 transmission assembly is working. The third belt 316 or the fourth belt 315 rotates to transport the plate. The second upper adjusting plate 317 and the second lower adjusting plate 318 are respectively movably mounted on the second flip plate 311 and move up and down to adjust the distance between the fourth belt 315 and the third belt 316 to clamp the plate. Specifically, the second upper adjusting plate 317 is located in the cavity enclosed by the fourth belt 315, and the second lower adjusting plate 318 is located in the cavity enclosed by the third belt 316.

[0030] Example 2

[0031] Reference Figure 1-4As shown, based on the technical solution of Embodiment 1, a flipping conveyor device for flipping the front and back sides of a sheet metal, specifically regarding the structure of the second flipping lock assembly 34, has a sixth motor 341 mounted on a sixth fixed plate. The sixth fixed plate is connected to the telescopic shaft of the second horizontal cylinder 343, which is fixed on a second mounting plate 35. The second mounting plate 35 has a through hole machined to accommodate the horizontal movement of the sixth motor 341. Under the drive of the second horizontal cylinder 343, the sixth motor 341, together with the sixth gear 342, adjusts its position horizontally within the through hole, enabling it to approach and correctly mesh with either the third gear 312 or the fourth gear 313, thus locking it in place. This ensures that the sheet metal clamped between the fourth belt 315 and the third belt 316 meets the required level. In other words, the second flipping lock assembly 34 and the symmetrical gear design ensure that the levelness meets the standard after flipping. The connection relationship between the first mounting plate 25 and the first flipping lock assembly 24 on the movable track structure 2 is similar, and so on, without further elaboration.

[0032] Furthermore, the second upper adjusting plate 317 and the second lower adjusting plate 318 are respectively connected to the second upper and lower adjusting slider group, which can be referred to accordingly. Figure 2 The first vertical adjustment slider group 219 is designed with specific features. The second vertical adjustment slider group includes a third slider and a fourth slider. The third slider and the fourth slider are respectively connected to the second lower adjustment plate 318 and the second upper adjustment plate 317 and are slidably set on the second vertical slide rail. For example, the third slider is connected to the second lower adjustment plate 318 through a connector. The connector can pass through the second flap 311 and move up and down. The second vertical slide rail is fixed on the second flap 311. The second lower adjustment plate 318 and the second upper adjustment plate 317 are respectively driven by two fourth lifting cylinders fixed on the second flap 311.

The purpose is to ensure that after the second flip plate 311 completes a 180-degree flip in both directions, it can still drive the third belt 316 transmission component or the fourth belt 315 transmission component through the second flip lock component 34. The second lower adjusting plate 318 and the second upper adjusting plate 317 can still adjust the distance to clamp the conveyed plate.

[0033] Furthermore, the second upper adjusting plate 317, the second lower adjusting plate 318, the third belt 316, the fourth belt 315, and multiple pulleys are all located inside the second flap 311, while the third gear 312, the fourth gear 313, the third slider, the fourth slider, the second vertical slide rail, and the fourth lifting cylinder are all located outside the second flap 311.

The second fixed shaft 314 is connected to one end of the third synchronous belt transmission assembly 53, and one end of the third synchronous belt transmission assembly 53 is connected to the transmission shaft 54. Third synchronous pulleys are installed on both the second fixed shaft 314 and the transmission shaft 54 ​​to transmit power in conjunction with the third synchronous belt. Specifically, the third synchronous belt drive assembly 53 includes two third synchronous pulleys and a third synchronous belt. The second fixed shaft 314 is fixed at the center of the second flip plate 311 and rotatably connected to the second mounting plate 35. A bearing seat is provided on the second mounting plate 35 to accommodate the second fixed shaft 314. The drive shaft 54 ​​is connected to the output shaft of the flipping mechanism 5. The flipping mechanism 5 includes a second motor 51 and a second reducer. The second motor 51 drives the output shaft of the second reducer to rotate at a reduced speed. Furthermore, the drive shaft 54 ​​is also connected to the second synchronous belt drive assembly 52. ​​The second synchronous belt connects to the first fixed shaft 214, which is mounted on the first flip plate and rotatably connected to the first mounting plate 25. The second motor 51 provides the power for the entire flipping action, simultaneously driving the first and second flip plates 311 to rotate around the axial direction of the second fixed shaft 314. The flipping angle is 180 degrees, allowing the front and back positions of the plates to be interchanged. The positional relationship between the first fixed shaft 214 and the first flip plate on the movable track structure 2 is similar, and so on, without further explanation.
