Description

Technical Field

[0001] The utility model relates to the technical field of additive manufacturing, and in particular to a pre-printing device with an automatic winding function. Background Art

[0002] Direct writing micro-printing technology is a high-precision ink direct writing additive manufacturing technology. With the continuous development of science and technology, direct writing micro-printing technology is applied to high-precision and micro-size occasions such as semiconductor packaging and display panel manufacturing.

[0003] In direct-write micro-printing technology, usually before starting formal printing, pre-printing is required in a specific area to verify whether the material output is normal. The usual practice in the prior art is to pre-print a line segment of a certain length on a specific silicon wafer or glass plate, and then manually or with an observation camera to check whether the printing effect is qualified, and finally wipe off the pre-printed material manually or with a wiping mechanism.

[0004] However, the method of manually wiping off the printed material after pre-printing is not suitable for automated production lines, because it is impossible to arrange a separate position in the production line to complete this task. At the same time, if the printed material is wiped off with a wiping mechanism, it will increase the complexity of the structure and increase the working time of the entire process, affecting the overall printing efficiency and printing accuracy.

[0005] Chinese application number CN201810939224 discloses a 3D printing system and a 3D printing method, including a feeding mechanism, a printing platform and an imaging mechanism. The feeding mechanism includes a printing conveyor belt and multiple supply tanks. The multiple supply tanks can discharge multiple printing materials layer by layer onto the printing conveyor belt, and the printing conveyor belt can transport the printing materials to the printing platform.

[0006] In the above-disclosed method, when 3D printing is performed, the printing material is discharged layer by layer onto the printing conveyor belt through the material supply tank, and the printing material is transported to the carrier plate for printing through the printing conveyor belt. However, since the pre-printing of the above-mentioned printing method is performed on the carrier plate, the surface of the carrier plate needs to be cleaned after the pre-printing. Manual cleaning is time-consuming and labor-intensive. At the same time, when there is pre-printing residue on the carrier plate, it will also affect the accuracy of subsequent printing on the printing conveyor belt. Utility Model Content

DETAILED DESCRIPTION

[0026] The embodiments of the utility model are described in detail below with reference to the accompanying drawings.

[0027] like Figure 1-Figure 5As shown, a pre-printing device with an automatic winding function includes a pre-printing box 1 and a pre-printing area 2 formed on the pre-printing box 1; an adsorption block 3 and a pre-printing coil 4 adsorbed on the adsorption block 3 are provided in the pre-printing area 2, and a reeling wheel group 5 and a reeling wheel group 6 for driving the pre-printing coil 4 to be transported are provided on the pre-printing box 1; a guide wheel group 8 for tensioning the pre-printing coil 4 is provided on the pre-printing box 1.

[0028] The pre-printed coil 4 is wound on the unwinding wheel group 5, and the pre-printed coil 4 passes through the guide wheel group 8, and the pre-printed coil 4 is tensioned under the action of the guide wheel group 8. The pre-printed coil 4 passes through the pre-printing area 2 during the transmission process, and is wound up in the pre-printing area 2 and by the winding wheel group 6.

[0029] The adsorption block 3 is located below the pre-printed coil 4. The pre-printed box 1 is provided with an adjustment frame 7 for adjusting the position of the adsorption block 3. The adsorption block 3 is fixed to the top of the adjustment frame 7 by bolts, so that the adsorption block 3 can be adjusted synchronously with the adjustment of the adjustment frame 7. The adjustment frame 7 can realize adjustment in the XYZ axis direction. The top of the adsorption block 3 is used to adsorb the pre-printed coil 4, so as to form a printing plane on the surface of the pre-printed coil 4 after adsorption. The adjustment frame 7 can realize fine adjustment of the flatness of the printing plane. The adjustment frame 7 can select the OMOS-CE05-3R model.

[0030] A sensor 9 for detecting whether the pre-printed coil 4 is out of material is installed on the pre-print box 1. The sensor 9 is set toward the pre-printed coil 4. The pre-printed coil 4 is always in the same travel trajectory during the transmission process under the action of the guide wheel group 8. The sensor 9 is used to identify whether there is a lack of material toward the pre-printed coil 4 to determine whether the entire device is in a short-material device.

[0031] The sensor 9 is electrically connected to the winding wheel group 6. When the sensor 9 detects that the entire device is in a material shortage state, the sensor 9 transmits a signal to the winding wheel group 6 to stop the winding wheel group 6. Since the pre-printed coil 4 cannot be tensioned at this time, the pre-printed coil 4 adsorbed on the adsorption block 3 is prone to wrinkles, thereby affecting the pre-printing effect.

[0032] The sensor 9 is arranged at the front end of the feed port of the pre-printing area 2 , so that when the sensor 9 detects that the entire device is in a state of lack of material, the operation of the entire device can be stopped immediately to avoid invalid pre-printing in the pre-printing area 2 .

[0033] The pre-print box 1 is provided with a coding wheel group 10 which is in contact with the pre-printed coil 4. An encoder for controlling the rotation angle of the winding wheel group 6 is provided in the coding wheel group 10. The coding wheel group 10 rotates synchronously with the transmission of the pre-printed coil 4, so that the transmission distance of the pre-printed coil 4 is the rotation circumference of the coding wheel group 10. The encoder obtains the transmission distance of the pre-printed coil 4 by identifying the rotation angle of the coding wheel group 10, thereby controlling the rotation angle of the winding wheel group 6, so that the rotation circumference of the winding wheel group 6 is consistent with the transmission distance of the pre-printed coil 4, thereby ensuring that the length of the pre-printed coil 4 is consistent each time, reducing the waste of the pre-printed coil 4.

[0034] The encoding wheel group 10 is located above the winding wheel group 6, and the encoding wheel group 10 is located at the rear end of the discharge port of the pre-printing area 2. The encoding wheel group 10 detects the pre-printed coil 4 after pre-printing, thereby ensuring that the winding length of the pre-printed coil 4 is more accurate.

[0035] The unwinding wheel assembly 5 comprises a damping fixing plate 51 mounted on the pre-printing box 1 and a damper 52 connected to the damping fixing plate 51 , and a passive wheel pressure plate 53 and a passive wheel plate 54 for loading the pre-printing roll 4 are rotatably connected to the damper 52 .

[0036] The damping fixing plate 51 is fixedly connected to the pre-print box 1 by bolts, the damper 52 is arranged in the pre-print box 1, the passive wheel pressure plate 53 is connected to the damper 52 by a rotating shaft, and the rotating shaft passes through the damping fixing plate 51, the passive wheel pressure plate 53 and the passive wheel plate 54 rotate synchronously, and the rotation of the passive wheel pressure plate 53 and the passive wheel plate 54 is realized by the transmission of the pre-printed roll 4.

[0037] During use, the pre-printed coil 4 is first placed on the passive wheel plate 53, and then the passive wheel pressure plate 54 is used to press the pre-printed coil 4 to complete the loading of the pre-printed coil 4. The damper 52 can provide stable damping to the unwinding wheel group 5 to ensure stable unwinding of the unwinding wheel group 5.

[0038] The winding wheel group 6 includes a winding motor 61 installed in the pre-print box 1 and a driving wheel 62 rotatably connected to the winding motor 61. The driving wheel 62 is provided with a driving wheel pressure plate 63 for pressing the pre-printed coil 4. The winding motor 61 is used to drive the rotation of the driving wheel 62, thereby driving the transmission of the pre-printed coil 4. The driving wheel pressure plate 63 is used to press the pre-printed coil 4 on the driving wheel 62 to ensure the winding stability of the winding wheel group 6.

[0039] The guide wheel group 8 includes a first guide roller 81, a second guide roller 82 and a third guide roller 83 which are relatively arranged on both sides of the adsorption block 3, and the first guide roller 81, the second guide roller 82 and the third guide roller 83 are staggered on the inner and outer sides of the pre-printed roll 4, and the relatively arranged first guide roller 81 is located in the pre-printing area 2.

[0040] The first guide roller 81 and the third guide roller 83 are arranged on the inner side of the pre-printed coil 4, and the second guide roller 82 is arranged on the outer side of the pre-printed coil 4, so that the stability of the pre-printed coil 4 during the transmission process is achieved under the action of the staggered first guide roller 81, the second guide roller 82 and the third guide roller 83.

[0041] An installation adjustment block 11 for installing the adjustment frame 7 is installed on the pre-print box 1, and a waist-shaped hole 12 for coarse adjustment of the adjustment frame 7 is formed on the installation adjustment block 11. The waist-shaped hole 12 is vertically arranged, and the adjustment frame 7 is installed at different positions of the waist-shaped hole 12 of the installation adjustment block 11 by bolts, thereby realizing coarse adjustment of the height of the adjustment frame 7.

[0042] A plurality of adsorption holes 31 for adsorbing the pre-printed web 4 are formed on the surface of the adsorption block 3, and an adsorption pipeline 32 connected to the adsorption hole 31 is provided on one side of the adsorption block 3. An adsorption connector 13 connected to the adsorption pipeline 32 is formed on the pre-print box 1. A wiring harness plug 14 electrically connected to the sensor 9, the adjustment frame 7 and the winding wheel group 6 is also formed on the pre-print box 1.
