[0047] Example

[0048] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 This embodiment provides a transfer platform device 400 for printing on a product surface, especially for printing on a complex curved surface or a large area pattern.

[0049] In this embodiment, the transfer platform device 400 includes a support base 410, a floating support module 420 and a transfer film 450. The support base 410 can be disposed on a carrier substrate 460, for example, on a frame of a product printing device.

[0050] The floating support module 420 is disposed on the support base 410. The transfer film 450 is disposed on the floating support module 420. The floating support module 420 has a floating stroke perpendicular to the direction of the support base 410, so that the transfer film 450 has a floating stroke perpendicular to the direction of the support base 410. The pattern layer 453 to be transferred can be printed on the transfer film 450.

[0051] Furthermore, the support base 410 is provided with hollow holes 411 for avoiding the transfer film 450, so as to apply force on both sides of the transfer film 450 during transfer, or to facilitate the transfer film 450 to contact the surface of the product for transfer.

[0052] The floating support module 420 includes a printing seat 421 and two floating support seats 422. The two floating support seats 422 are both disposed on the support base 410 and are arranged in a counterposition (along the length direction of the support base 410). The printing seat 421 is disposed between the two floating support seats 422 and connected to the two floating support seats 422, and the transfer film 450 is disposed on the printing seat 421.

[0053] See also Figure 4 In some embodiments, the printing seat 421 is provided with a positioning structure for positioning the transfer film 450, such as a positioning groove or a positioning protrusion.

[0054] See also Figure 1 , Figure 2 and Figure 3 , the floating support seat 422 includes a limit support 4220 and a floating support 4223. In the present embodiment, two limit supports 4220 are provided, and the two limit supports 4220 are both provided on the support base 410 and are arranged in a counter-positioned manner (along the width direction of the support base 410). The floating support 4223 is provided between the two limit supports 4220, and the floating support 4223 is respectively slidably matched with the two limit supports 4220 through a linear guide assembly 4225. Among them, the linear guide assembly 4225 extends in a direction perpendicular to the plane where the support base 410 is located, so that the floating support 4223 has an up and down floating stroke perpendicular to the plane where the support base 410 is located.

[0055] Furthermore, each limiting support 4220 has an upper limit portion 4221 and a lower limit portion 4222, and a movable limiting block 4224 is provided on the floating support 4223, and the movable limiting block 4224 is located between the upper limit portion 4221 and the lower limit portion 4222. It can be understood that the upper limit portion 4221 is used to limit the maximum stroke of the movable limiting block 4224 moving upward, and the lower limit portion 4222 is used to limit the maximum stroke of the movable limiting block 4224 moving downward. In this way, the upper limit portion 4221 and the lower limit portion 4222 are used to limit the floating stroke of the floating support 4223 in the limiting support 4220, and prevent the limiting support 4220 from detaching from the limiting support 4220 during the floating process.

[0056] Optionally, the upper limit portion 4221 and the lower limit portion 4222 may use mechanical limit blocks.

[0057] In this embodiment, the printing seat 421 and the floating support seat 422 are rotatably matched, so that the transfer seat can drive the transfer film 450 to flip in the vertical plane, so that the side of the transfer film 450 printed with the pattern layer 453 faces the product, thereby adapting to the transfer of the product in different directions of the transfer film 450, and the transfer is more flexible.

[0058] For example, when the product is placed under the transfer film 450, the pattern layer 453 is first printed on the transfer film 450 by a screen printing device (the pattern layer 453 is located on the side of the transfer film 450 facing away from the product), and then the transfer seat is turned 180 degrees so that the pattern layer 453 on the transfer film 450 faces the product for easy transfer. It can also be understood that the hollow hole 411 on the support base 410 can also provide an escape space for the turning of the printing seat 421 and the transfer film 450.

[0059] Specifically, two ends of the printing seat 421 are respectively provided with a rotating shaft 4210 , and the rotating shaft 4210 and the corresponding floating support 4223 are rotatably matched through a bearing 4211 .

[0060] Furthermore, the transfer platform device 400 further includes a flip driving module 430, which is disposed on a floating support 4223 of one of the floating support seats 422 and is in driving connection with a rotating shaft 4210 at one end of the printing seat 421, and is used to drive the printing seat 421 to flip and shift. Thus, the entire flip driving module 430 is mounted on the corresponding floating support 4223, so that it can float up and down synchronously with the floating support 4223.

[0061] Specifically, the flip driving module 430 includes a flip motor 431 and a reducer 432 connected to the flip motor 431. The reducer 432 is installed on one side of the corresponding floating support 4223. The output shaft of the reducer 432 is connected to the rotating shaft 4210 at the corresponding end of the printing seat 421 by axial transmission, such as flange connection or coupling connection.

[0062] See also Figure 1 , Figure 2 and Figure 3 In this embodiment, the floating support module 420 further includes a counterweight adjustment mechanism 423, which is disposed on the support base 410 and connected to a floating support 4223 in another floating support seat 422. It is understandable that since the flip drive module 430 is installed on one of the floating supports 4223 of the two floating support seats 422, the other floating support 4223 will be affected by the gravity of the flip drive module 430, which will cause the force of the other floating support 4223 to be unbalanced, and the entire printing seat 421 will tilt, which will eventually affect the printing quality. In this way, the other floating support 4223 is connected through the counterweight adjustment mechanism 423 to balance the gravity of the flip drive module 430, thereby ensuring the printing quality.

[0063] It should also be explained that when transferring is carried out, for example, when the transfer film 450 is printed with pattern ink, the printing seat 421 will be lifted up to a preset height by the printing support table (not shown), and the counterweight adjustment mechanism 423 will tighten the floating support 4223 at this time, thereby giving the floating support 4223 a pulling force opposite to the lifting direction (a downward pulling force in this application), and by adjusting the size of the pulling force, the entire floating support module 420 is kept balanced to ensure the flatness of the transfer film 450 on the horizontal plane.

[0064] Optionally, the counterweight adjustment mechanism 423 includes a counterweight cylinder, and the tension of the counterweight cylinder can be adjusted by adjusting the air valve of the counterweight cylinder, so as to maintain balance with the gravity of the entire floating support module 420. In some embodiments, the counterweight adjustment mechanism 423 can also be selected as an oil cylinder, an electric cylinder or an electric push rod.

[0065] See also Figure 1 , Figure 3 and Figure 5 In some embodiments, the transfer platform device 400 further includes a linear drive module 440, which is disposed on the carrier substrate 460 and connected to the support base 410. In this embodiment, the linear drive module 440 is disposed on the frame of the product printing device, and the frame is provided with a screen printing station and a transfer station. The linear drive module 440 can drive the support base 410 and drive the transfer film 450 on the floating support module 420 to move between the screen printing station and the transfer station. Among them, the screen printing station is provided with a screen printing device, and the transfer station is provided with a transfer device.

[0066] Optionally, the linear drive module 440 includes but is not limited to a linear motor, a pneumatic cylinder, an oil cylinder, an electric push rod, an electric cylinder or a screw motor.

[0067] Please also read Figure 4 The transfer film 450 includes a skeleton frame 451 and an elastic film 452 disposed on the skeleton frame 451 , and the skeleton frame 451 is disposed on the floating support module 420 .

[0068] Optionally, the skeleton frame 451 and the printing seat 421 of the floating support module 420 are detachably connected, such as by screw connection or snap connection, so as to facilitate subsequent maintenance and replacement of the transfer film 450 .

[0069] Optionally, the elastic film 452 is made of elastic materials such as natural rubber, silicone, chloroprene rubber, plastic film, etc. This ensures that the elastic film 452 has good elasticity and viscosity. Good elasticity can achieve the effect of easy adhesion between the film and the product, and good viscosity can meet the function of printing the ink pattern layer 453. Natural rubber is preferred.

[0070] See also Figures 1 to 5 Furthermore, this embodiment also provides a product printing device. The product printing device includes a frame, a screen printing device, a transfer device, and a transfer platform device 400 provided above. The screen printing device, the transfer device, and the transfer platform device 400 are all arranged on the frame; the screen printing device is used to screen print a designated pattern on the elastic film 452 on the transfer platform device 400, and the transfer platform device 400 moves with the elastic film 452 to the position of the transfer device, and the pattern on the elastic film 452 is transferred to the product through the transfer device.

[0071] Compared with the prior art, the transfer platform device 400 provided in the present application can utilize the floating effect of the floating support module 420 by arranging the transfer film 450 on the floating support module 420, so that the transfer film 450 has a certain floating buffer stroke in the support base 410. When applied to transfer in product printing equipment, the floating effect of the floating support module 420 can provide a certain buffer and adjustment when the transfer film 450 is lifted and clamped, thereby preventing the transfer film 450 from being offset and damaged due to direct impact, and also preventing the impact force from being directly transmitted to the entire transfer platform device 400, thereby ensuring the printing accuracy and quality, and at the same time extending the service life of the transfer film 450 and the entire transfer platform device 400.

[0072] Similarly, when the transfer film 450 is lifted for positioning or lifted for cleaning, a buffer is provided to protect the transfer film 450 and the entire transfer platform device 400 .

[0073] The transfer platform device can also cooperate with an external screen printing device and transfer device to achieve high-precision pattern printing on curved surface products.
