Description

Technical Field

[0001] This utility model belongs to the field of smart card manufacturing, specifically relating to a flipping device for card DOD production. Background Technology

[0002] UV inkjet printing is commonly known as DOD (Dual Ink) printing. It boasts advantages such as safety, environmental friendliness, vibrant colors, and strong adhesion. With continuous technological advancements, DOD printing is becoming increasingly prevalent in the printing industry. Currently, it is basically divided into two types: scanning printing, where the ink is gradually layered through multiple reciprocating printhead movements, and single-pass printing, where the printhead is stationary and the material moves. Single-pass printing is more than ten times more efficient than multiple-pass printing. However, because the clarity of single-pass printing was previously significantly lower than that of multiple-pass printing, it was rarely used for high-precision and high-definition printing, especially for images. Now, the quality of single-pass printing has greatly improved. Besides monochrome printing, multi-printhead color mixing for color printing has also been successfully achieved. With the continuous expansion of market usage, the cost of DOD printing, including inkjet printers, is decreasing significantly. Its development direction is to improve printing quality and efficiency while saving space and labor costs. To achieve high-quality printing, two conditions are required: firstly, the material movement needs to be uniform, stable, and precise; secondly, the ink flow and timing control of multiple printheads must be precise. The latter is a technology that the inkjet printer itself needs to continuously improve.

[0003] However, in the DOD printing process, it is necessary to print on both sides of the card, so a card flipping device is required to flip the card. However, the existing card flipping device needs to clamp and release the card when flipping it. This makes the operation of the card flipping device more complicated during the card flipping process, which is not conducive to improving the flipping efficiency. Correspondingly, the structure of the card flipping device is also more complicated. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a flipping device for card DOD production. The flipping device can flip the card 180 degrees, which has higher flipping efficiency and simpler structure.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is:

[0006] A flipping device for card DOD production includes a support, a flipping mechanism disposed within the support, and a rotary drive mechanism for driving the flipping mechanism to rotate.

[0007] The flipping mechanism includes flipping seats disposed on both sides of the support; the flipping seats are rotatably connected to the support via rotating shafts; the inner side of the flipping seats is provided with a groove extending along its length direction; the rotary drive mechanism is used to drive the rotating shafts on the flipping seats on both sides to rotate synchronously.

[0008] It also includes a limiting mechanism for limiting the end of the card during the flipping process. The limiting mechanism includes a roller and a vertical drive mechanism for driving the roller to move vertically. When the card needs to be flipped, the vertical drive mechanism drives the roller to rise and causes the wheel surface of the roller to press against the end of the card. The rotation drive mechanism drives the card to flip 180 degrees with the wheel surface of the roller as the limiting surface.

[0009] Preferably, the vertical drive mechanism includes a lifting base and a lifting cylinder, wherein the roller is rotatably connected to the lifting base; the lifting cylinder is mounted on the support, and the piston rod is connected to the lifting base.

[0010] Preferably, the rotary drive mechanism includes a rotary motor and a synchronous transmission mechanism, wherein the rotary motor is mounted on the support; and the synchronous transmission mechanism is used to transmit the power of the rotary motor to the rotating shafts in the flip seats on both sides.

[0011] Preferably, the synchronous transmission mechanism includes a transmission shaft; the transmission shaft is connected to the main shaft of the rotary motor via a coupling, and the transmission shaft is connected to the rotating shafts on the flip seats on both sides via a belt transmission mechanism.

[0012] Preferably, the support is provided with a limiting component, which is used to prevent the card from being thrown out due to centrifugal force when flipped.

[0013] Preferably, the limiting component includes an arc-shaped limiting plate and baffles disposed on both sides of the arc-shaped limiting plate, wherein the arc-shaped limiting plate is mounted on the support and located above the flipping seat; during the flipping process, one end of the card contacts the wheel surface of the roller, and the other end contacts the arc-shaped limiting plate.

[0014] Preferably, the axial direction of the arc-shaped limiting plate coincides with the axial direction of the rotating shaft.

[0015] Preferably, the inner diameter of the arc-shaped limiting plate is equal to the length of the card.

[0016] Preferably, the baffle is semi-circular.

[0017] Preferably, the rotary drive mechanism further includes a detection mechanism for detecting the rotation angle of the drive shaft. The detection mechanism includes a sensor mounted on the support and a rotating disk mounted on the drive shaft. The rotating disk is located inside the detection port of the sensor and has two sets of notches arranged symmetrically at 180 degrees.

[0018] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0019] 1. The flipping device for card DOD production of this utility model drives the flipping seats on both sides to flip 180 degrees through a rotary drive mechanism, thereby causing the cards located in the flipping seats on both sides to flip 180 degrees. During the flipping process, the roller is driven to rise through the vertical drive mechanism, so that one end of the card is pressed against the wheel surface of the roller. Under the drive of the rotary drive mechanism, the card rotates 180 degrees with the wheel surface of the roller as the rotation fulcrum, thereby realizing the flipping of the card. In the above process, the flipping seat does not need to clamp the card. Correspondingly, after the card is flipped, it does not need to be released, which can greatly improve the flipping efficiency.

[0020] 2. Since the flipping device for card DOD production of this utility model does not require clamping the card, there is no need to set up a corresponding clamping mechanism. Therefore, the structure of the flipping device for card DOD production of this utility model is simpler and the manufacturing cost is lower. Attached Figure Description

[0023] Figure 5 This is a diagram illustrating the flipping of a card. Detailed Implementation

[0024] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of the present invention is not limited thereto.

[0025] See Figures 1-5 The flipping device for card DOD production of this utility model includes a support 1, a flipping mechanism disposed within the support 1, and a rotary drive mechanism for driving the flipping mechanism to rotate.

[0026] The flipping mechanism includes flipping seats 10 disposed on both sides of the support 1; the flipping seats 10 are rotatably connected to the support 1 via a rotating shaft; the inner side of the flipping seat 10 is provided with a groove extending along its length direction; the grooves in the flipping seats 10 on both sides are arranged opposite to each other, and the two sides of the card to be flipped enter the corresponding grooves in the flipping seats 10 respectively.

[0027] The rotary drive mechanism is used to drive the rotating shafts on both sides of the flipping seats 10 to rotate synchronously. The rotary drive mechanism includes a rotary motor 2 and a synchronous transmission mechanism. The rotary motor 2 is mounted on the support 1. The synchronous transmission mechanism is used to transmit the power of the rotary motor 2 to the rotating shafts in the flipping seats 10 on both sides. The synchronous transmission mechanism includes a transmission shaft 6. The transmission shaft 6 is connected to the main shaft of the rotary motor 2 through a coupling, and the transmission shaft 6 is connected to the rotating shafts on both sides of the flipping seats 10 through a belt transmission mechanism 7. The rotary motor 2 drives the transmission shaft 6 to rotate, thereby driving the two sets of belt transmission mechanisms 7 to work synchronously, thus realizing the synchronous rotation of the two sets of flipping seats 10.

[0028] To ensure flipping accuracy, the rotary drive mechanism further includes a detection mechanism for detecting the rotation angle of the drive shaft 6. The detection mechanism includes a sensor 4 mounted on the support 1 and a rotating disk 3 mounted on the drive shaft 6. The rotating disk 3 is located inside the detection port of the sensor 4 and has two sets of notches arranged symmetrically at 180 degrees. When the drive shaft 6 rotates, the rotating disk 3 also rotates. In the initial state, the sensor 4 detects the notches on the rotating disk 3. During the 180-degree flipping of the card, if the sensor 4 detects the notches on the rotating disk 3 again, it indicates that the card has been flipped 180 degrees.

[0029] See Figures 1-5 The flipping device for card DOD production of this utility model also includes a limiting mechanism for limiting the end of the card during the flipping process. The limiting mechanism includes a roller 9 and a vertical drive mechanism for driving the roller 9 to move vertically. The vertical drive mechanism includes a lifting seat and a lifting cylinder 8. The roller 9 is rotatably connected to the lifting seat. The lifting cylinder 8 is mounted on the support 1, and the piston rod is connected to the lifting seat. When the card needs to be flipped 180 degrees, the vertical drive mechanism drives the roller 9 to rise, so that one end of the card abuts against the wheel surface of the roller 9. Then, under the drive of the rotation drive mechanism, the card rotates 180 degrees with the wheel surface of the roller 9 as the rotation fulcrum, thereby realizing the flipping of the card.

[0030] See Figures 1-5The support 1 is provided with a limiting component 5, which is used to prevent the card from being thrown out due to centrifugal force during flipping. The limiting component 5 includes an arc-shaped limiting plate and baffles disposed on both sides of the arc-shaped limiting plate. The arc-shaped limiting plate is installed on the support 1 and is located above the flipping seat 10. During the flipping process, one end (i.e., the inner side) of the card contacts the wheel surface of the roller 9, and the other end (i.e., the outer side) contacts the arc-shaped limiting plate. This can limit the inner and outer sides of the card, so that the card will not move radially during the flipping process, thereby ensuring the flipping accuracy of the card.

[0031] In this embodiment, the axial direction of the arc-shaped limiting plate coincides with the axial direction of the rotating shaft, and the inner diameter of the arc-shaped limiting plate is equal to the length of the card; thus, during the flipping process, the outer side of the card is always in contact with the inner side of the arc-shaped limiting plate, thereby causing the card to move radially; in addition, the baffle is semi-circular, and a clearance hole is provided at the position where it contacts the belt drive mechanism 7.

[0032] The above are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above content. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
