Description

Technical Field

[0001] This utility model belongs to the technical field of circuit board production equipment, and specifically relates to a flipping device. Background Technology

[0002] In the production of flexible printed circuit boards (FPCBs), it is sometimes necessary to flip the circuit boards placed in a carrier before proceeding to the next step. Before the flipping operation, since the carrier and circuit boards are often located on the production line, a transfer mechanism is needed to move them from the previous production line to the flipping mechanism. The flipping mechanism then uses its clamping components to grip both ends of the carrier from the transfer mechanism and flips it. After flipping, the carrier and circuit boards are placed back on the transfer mechanism, which then places them on the next production line. However, this flipping method, because it can only grip both ends of the carrier, often results in the circuit boards shifting and becoming misaligned within the carrier during the flipping process, affecting the accurate positioning of subsequent operations. Moreover, the process of transferring from the production line, flipping, and then transferring back to the production line involves many steps, is time-consuming, and complex, resulting in higher production costs. Summary of the Invention

[0003] In view of the problems existing in the prior art, the main purpose of this utility model is to provide a flipping device that prevents product misalignment during the flipping process and can be connected to the production line.

[0004] To achieve the aforementioned main objectives, this utility model provides a flipping device, including a support base and a rotating body. The support base includes a first support base and a second support base for rotatably supporting the rotating body. A flipping drive mechanism is mounted on the first support base for driving the rotating body to flip around a central axis. The rotating body includes a mounting frame, an upper pressing mechanism, a lower pressing mechanism, and a conveying mechanism. The mounting frame includes an upper mounting plate and a lower mounting plate, wherein the upper pressing mechanism is mounted on the upper mounting plate and includes an upper pressing part movable in a direction perpendicular to the central axis. The lower pressing mechanism is mounted on the lower mounting plate. The lower mounting plate of the mounting frame includes a lower pressing part that can move along a direction perpendicular to the central axis; the conveying mechanism is hollow and includes two conveying tracks installed inside the mounting frame and arranged opposite each other, the conveying direction of which is perpendicular to the central axis and perpendicular to the moving direction of the upper and lower pressing parts; when the rotating body is driven to flip, the upper and lower pressing parts are located in a position that extends into the internal space of the conveying mechanism and clamps the product; when the product is conveyed in the conveying mechanism along the conveying direction, the upper and lower pressing parts are located in a position that is separated from the product.

[0005] As can be seen from the above solution, when the product, including the upper and lower clamping parts and the circuit board, is flipped, the circuit board is clamped in the carrier because the upper and lower clamping parts extend into the internal space of the conveying mechanism and thus will not shift. In addition, the conveying mechanism is located in the rotating body and can receive the product to be flipped from the previous conveyor line and connect to the next conveyor line after flipping. There is no need to set up other mechanisms for transfer, saving transfer mechanisms and transfer processes. Therefore, during the flipping process, the product will not only not be misaligned, but can also be connected to the production line, resulting in high production efficiency.

[0006] According to a specific embodiment of the present invention, each conveying track includes two synchronous conveyor belts, and the two ends of the product are respectively located between the two synchronous conveyor belts.

[0007] As can be seen from the above scheme, by using two synchronous conveyor belts, the upper part of the lower conveyor belt plays a major supporting role and conveys the product before the flip. After the flip, the conveyor belt that was previously located above moves to the lower part to play a major supporting role and convey the product. Thus, before and after the flip, the product can be conveyed in the conveying mechanism along the conveying direction.

[0008] According to a specific embodiment of this utility model, at least two mounting guide rails are provided within the mounting frame, and each conveying rail is provided with a corresponding mounting sleeve that is respectively fitted onto the outside of the mounting guide rail. Through the cooperation between the mounting sleeve and the mounting guide rail, the conveying rail can be reliably installed in the rotating body.

[0009] According to a specific embodiment of this utility model, the conveying track is slidable along the mounting guide rail. One or both of the upper and lower mounting plates are provided with a slider connected to the conveying track and a fixing structure for fixing the slider. Fixing the slider with the fixing structure secures the conveying track relative to the mounting guide rail. Opening the fixing structure allows adjustment of the distance between the conveying tracks to accommodate the conveying of different types of products.

[0010] According to a specific embodiment of this utility model, a blocking member is provided on the lower pressing part. After the product is conveyed to contact the blocking member, the conveying mechanism stops conveying the product, the upper pressing part moves downward, and the lower pressing part moves upward, clamping the product between them. The rotating body rotates 180 degrees. After the rotation is completed, the upper and lower pressing parts separate from the product, and the product can be further conveyed along the conveying direction. The conveying of the product is controlled by setting a blocking member, resulting in a simple structure and convenient control.

[0011] According to a specific embodiment of this utility model, the flipping drive mechanism includes a servo motor and a reducer. The rotation angle during flipping is precisely controlled by the servo motor and the reducer.

[0012] According to a specific embodiment of this utility model, a positioning structure is provided between the upper pressing part and the lower pressing part. By providing the positioning structure, the positioning accuracy of the product after flipping is ensured.

[0013] According to a specific embodiment of the present invention, the positioning structure includes a plurality of positioning pins and a plurality of positioning holes, wherein the positioning pins are disposed on either the upper pressing part or the lower pressing part, and the positioning holes are disposed on the other.

[0014] According to a specific embodiment of this utility model, the upper pressing mechanism further includes a buffer assembly disposed on the upper pressing part. The buffer assembly increases the pressing control surface, making the product fit better and less prone to misalignment.

[0015] According to a specific embodiment of this utility model, the lower pressing part has an elastic material layer on its surface that contacts the product. This reduces the impact on the product during pressing.

[0016] To more clearly illustrate the above-mentioned objectives, technical solutions, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0025] Many specific details are set forth in the following description to provide a full understanding of the present invention. However, it will be readily apparent to those skilled in the art that the present invention may be implemented in other ways different from those described herein. Therefore, other possible implementations that can be obtained by those skilled in the art based on the embodiments described herein are all within the scope of protection of this application.

[0026] like Figure 1 and Figure 2 As shown, the flipping device 100 includes a support base and a rotating body. The support base includes a first support base 11 and a second support base 12 for rotatably supporting the rotating body. The rotating body includes a mounting frame 20 and an upper pressing mechanism 30, a lower pressing mechanism 40, and a conveying mechanism 50 mounted thereon. The conveying mechanism 50 is hollow and includes two oppositely arranged first conveying rails 51 and second conveying rails 52. The flipping drive mechanism 13 is mounted on the first support base 11 and drives the mounting frame 20 to rotate, thereby driving the upper pressing mechanism 30, the lower pressing mechanism 30, and the conveying mechanism 50, i.e., the entire rotating body rotates synchronously.

[0027] like Figure 3 As shown, the first support base 11 includes a mounting plate 111 and an outer support 112. A drive connector 113 is provided on the mounting plate 111 for mounting and driving one end of the central shaft of the mounting frame 20. The flipping drive mechanism 13 is mounted on the mounting plate 111. In this embodiment, a servo motor 131 and a reducer 132 are used to drive the drive connector 113, further driving the mounting frame 20 to rotate. The servo motor 131 and reducer 132 are used to precisely control the rotation angle when the rotating body flips. It is understood that in other embodiments, the flipping drive mechanism may also be driven in other ways.

[0028] As shown in Figure 4, the second support 12 includes a mounting plate 121 and an outer support 122, and a shaft hole 123 is used to accommodate the other end of the central shaft of the mounting frame 20.

[0029] like Figure 5As shown, the mounting frame 20 includes an upper mounting plate 211, a lower mounting plate 212, and a frame formed by lateral mounting plates 213 and 214. At the central axis of the frame, the lateral mounting plate 213 is provided with a mounting joint 22 connected to the drive joint 113, and the lateral mounting plate 214 is provided with a protruding shaft 23, which is rotatably mounted on the first support 11 and the second support 12, respectively. Two upper mounting guide rails 261 are provided below the upper mounting plate 211, and two lower mounting guide rails 262 are provided above the lower mounting plate 212 for mounting the conveyor tracks 51 and 52. The upper mounting plate 211 is also provided with sliders 241 and 242, and a scale 2111 indicating the position of the sliders. The lower mounting plate 212 is provided with sliders 251 and 252 for connecting with the conveyor tracks 51 and 52. Each slider is provided with a limit groove, and each mounting plate is provided with a positioning hole 2112, which limits the position of each slider by positioning pins.

[0030] The connection method between the support base and the mounting frame is not limited to those described above. The flipping drive mechanism can also drive the mounting frame in other ways, as long as it can achieve stable rotation of the mounting frame and the rotation angle can be precisely controlled.

[0031] like Figure 6 As shown, the upper pressing mechanism 30 includes a drive unit 31, a mounting unit 32, and an upper pressing part 33. The drive unit 31 can be configured as a motor with a screw to drive the upper pressing part 33 to move in a direction perpendicular to the conveying direction and the central axis of the mounting frame 20. The mounting unit 32 is used to fix the upper pressing mechanism 30 on the upper mounting plate 211 of the mounting frame 20. The upper pressing part 33 is provided with a buffer assembly including an elastic buffer 34 and an upper pressing part 35. To make the movement of the upper pressing part 33 smoother, the upper pressing mechanism 30 is also provided with a cooperation structure of multiple guide posts 37 and guide sleeves 38. One end of each guide post 37 is connected to the connecting part 36, and the other end is connected to the upper pressing part 33. The guide sleeves 38 are fixedly connected to the mounting part 32.

[0032] like Figure 7As shown, the lower pressing mechanism 40 includes a drive unit 41, a mounting unit 42, and a pressing unit 43. The drive unit 41 can be configured as a motor with a screw to drive the lower pressing unit 43 to move in a direction perpendicular to the conveying direction and the central axis of the mounting frame 20. The mounting unit 42 is used to mount the lower pressing mechanism 40 on the lower mounting plate of the mounting frame. The lower pressing unit 43 is provided with an elastic material layer 431, positioning pins 431 and 432, and a blocking member 433. To make the movement of the lower pressing unit 43 smoother, the lower pressing mechanism 40 is also provided with a cooperation structure of multiple guide posts 47 and guide sleeves 48. One end of each guide post 47 is connected to the connecting part 46, and the other end is connected to the lower pressing unit 43. The guide sleeves 48 are fixedly connected to the mounting part 42. In addition, the upper pressing unit 33 can be provided with a clearance structure for the blocking member 433. By setting the blocking member to control the product conveying, the structure is simple and easy to control. By adding a cushioning component to increase the pressure control surface, the various parts of the product fit together better and are less prone to misalignment. By setting an elastic material layer, the impact on the product during pressing can be reduced.

[0033] It is understandable that the driving part of the pressing mechanism can also adopt a structure such as a cylinder, as long as it can realize the smooth movement of the pressing part in a direction perpendicular to the conveying direction and the central axis of the mounting frame.

[0034] Figure 8 The first conveying track 51 of the conveying mechanism is shown, and the second conveying track 52 is arranged approximately symmetrically to the first conveying track. Figure 8 As shown, the first conveying track 51 includes a drive unit 511, drive wheels 5121 and 5122, driven wheels 5123 and 5124, an upper conveyor belt 5131, a lower conveyor belt 5132, a mounting plate 514, an upper mounting sleeve 5151, and a lower mounting sleeve 5152. The drive unit 511 is used to rotate the drive wheels 5121 and 5122 in different directions, thereby driving the lower part of the upper conveyor belt 5131 and the upper part of the lower conveyor belt 5132 to move synchronously, and further driving the products conveyed on the conveyor belt to move along the conveying direction. The upper mounting sleeve 5151 is used to be fitted on the mounting guide rail 261, and the lower mounting sleeve 5152 is fitted on the mounting guide rail 262. The mounting plate 514 is also provided with a connecting part 5161 for fixed connection with the sliders 2141 and 2151. By employing two synchronous conveyor belts, the upper part of the lower conveyor belt 5132, which is located before the flip, plays a major supporting role and conveys the product. After the flip, the conveyor belt 5131, which was previously located above, moves to the lower part to play a major supporting role and convey the product. Thus, before and after the flip, the product can be conveyed in the conveying mechanism along the conveying direction.

[0035] When adjusting the distance between the two conveyor tracks 51 and 52 to accommodate different carriers, first remove the positioning pins installed on the upper mounting plate 211 and lower mounting plate 212 of the mounting frame 20. Pull the conveyor tracks 51 and 52 or the slider to allow the mounting sleeves of the conveyor tracks to slide on the mounting guides 261 and 262. Determine the required track width according to the position indicated on the scale 211, and then install the positioning pins in the appropriate positioning holes to fix the sliders and conveyor tracks. Through the cooperation of the mounting sleeves and the mounting guides, the conveyor tracks can be reliably installed in the rotating body. Fixing the slider with the fixing structure can fix the conveyor tracks relative to the mounting guides. Opening the fixing structure can adjust the distance between the conveyor tracks to accommodate the conveying of different types of products.

[0036] When flipping the product using this embodiment of the invention, the product, including the upper and lower loading devices and the circuit board, is conveyed from the upper conveyor line to the conveyor mechanism 50. Both ends of the product are located between the two conveyor belts of the first conveyor track 51 and the second conveyor track 52, respectively. The drive units 511 of the first conveyor track 51 and the second conveyor track 52 synchronously drive the conveyor belts to convey the product forward along the conveying direction. The product conveying stops when it contacts the blocking member 433 provided on the lower pressing part 43, and the drive unit 31 of the upper pressing mechanism 30 drives the upper pressing part. As part 33 moves downward, the driving part 41 of the lower pressing mechanism 40 drives the lower pressing part 43 to move upward until the upper pressing part 33 contacts the upper surface of the product, and the elastic material layer 431 of the lower pressing part 43 contacts the lower surface of the product. The upper and lower pressing parts move further, and the positioning pins 431 and 432 provided on the lower pressing part 43 are respectively inserted into the positioning holes of the upper pressing part 43. Under the elastic buffer of the buffer assembly and the elastic material layer 431, the product is tightly clamped by the upper and lower pressing parts under a certain pressure, and the circuit board in the carrier cannot move relative to the product.

[0037] The flipping drive mechanism 13 drives the rotating body, including the mounting frame 20, upper pressing mechanism 30, lower pressing mechanism 40, and conveying mechanism 50, to rotate 180 degrees. The upper pressing mechanism 30 rotates to the bottom while the lower pressing mechanism 40 rotates to the top. The drive part 31 of the upper pressing mechanism 30 drives the upper pressing part 33 to move downward away from the product, while the drive part 41 of the lower pressing mechanism 40 drives the lower pressing part 43 to move upward away from the product, until the upper and lower pressing parts are completely separated from the lower surface of the product without affecting the conveying of the product along the conveying direction. The drive parts 511 of the first conveying track 51 and the drive parts of the second conveying track 52 rotate in opposite directions to drive the synchronous conveyor belt to convey the flipped product to the next conveying line along the conveying direction. After the product is completely separated from the conveying mechanism, the flipping drive mechanism 13 drives the rotating body to rotate 180 degrees again, so that the upper pressing mechanism 30 returns to the top and the lower pressing mechanism 40 returns to the bottom, for the next flipping and conveying.

[0038] When a product, including an upper and lower loading device and a circuit board, is flipped, the upper and lower pressing parts extend into the internal space of the conveying mechanism to clamp it. The circuit board is clamped in the carrier and will not shift. In addition, the conveying mechanism is set in the rotating body and can receive the product to be flipped from the previous conveyor line and connect to the next conveyor line after flipping. There is no need to set up other mechanisms for transfer, saving transfer mechanisms and transfer processes. Therefore, during the flipping process, the product will not be misaligned and can be connected to the production line, resulting in high production efficiency.

[0039] While the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the scope of the invention. Any person skilled in the art may make modifications without departing from the scope of the invention; all variations or modifications made in accordance with the present invention shall be covered by the protection scope of the present invention.
