Abstract
Description
Technical Field
[0001] The utility model relates to a vertical cross-transfer printing mechanism of a screen printing machine, belonging to the technical field of screen printing machines. Background Art
[0002] In the prior art, the silicon wafer transfer of printing equipment mainly transfers the silicon wafer to the multi-station turntable printing table driven by a DD motor or to the cross-printing table driven by a linear motor along one direction through multiple single-section standard transfers for printing the silicon wafer. Generally, each standard single-section transfer is driven by a power source (servo motor or stepper motor) through a transmission shaft connected to a synchronous pulley and driven by a belt to drive the slave, thereby realizing the transfer of the silicon wafer plane.
[0003] For this single-direction transfer mechanism, whether it uses the turntable structure printing driven by a DD motor or the cross-table printing mechanism driven by a linear motor, it cannot make good overall use of reducing the incoming material time of the front-end standard transfer and cannot shorten the printing time (the CT beat of the mainstream printing machines in the current prior art is 0.8 - 0.85 s). Summary of the Utility Model
[0004] The vertical cross-transfer printing mechanism of a screen printing machine proposed by the utility model aims to overcome the above-mentioned deficiencies existing in the prior art, shorten the time of standard transfer, and further shorten the printing time.
[0005] Technical solution of the utility model: A vertical cross-transfer printing mechanism for a screen printing machine, the structure of which includes a standard transfer and handling mechanism group, a transfer component, a transfer printing platform group, and a wafer clamping mechanism. Among them, several standard transfer and handling mechanism groups along the wafer flow direction are arranged in parallel at intervals. The transfer printing platform group vertically penetrates the standard transfer and handling mechanism group. Each standard transfer and handling mechanism group is separated by the transfer printing platform group into a standard transfer and handling wafer feeding mechanism group on one side and a standard transfer and handling wafer discharging mechanism group on the other side. The standard transfer and handling wafer feeding mechanism group and the standard transfer and handling wafer discharging mechanism group respectively include several standard transfer and handling wafer feeding mechanisms arranged at intervals. A wafer clamping mechanism is arranged on the side of the standard transfer and handling wafer feeding mechanism of the standard transfer and handling wafer feeding mechanism group close to the transfer printing platform group. The transfer printing platform group is installed on the transfer component. The transfer printing platform group includes several transfer printing platforms arranged at intervals. The transfer component includes a linear module. The transfer printing platform is connected to the linear module through a bearing connecting plate. The silicon wafer is transferred by the standard transfer and handling wafer feeding mechanism group to the position of the wafer clamping mechanism, where the silicon wafer is aligned, and then transferred to the transfer printing platform group. At this time, the transfer component transfers the transfer printing platform to the corresponding printing station in the vertical direction of the standard transfer and handling mechanism group for printing. At the same time, at the corresponding other station, the wafer feeding operation is carried out on the wafers coming from the standard transfer and handling wafer feeding mechanism group. The station where the printing is completed returns to the original position of the standard transfer and handling wafer feeding mechanism group, and the silicon wafer is transferred out through the standard transfer and handling wafer discharging mechanism group. At the same time, another printing station prints the incoming wafers, and the movement is repeated like this.
[0006] Preferably, the standard transfer and handling wafer feeding mechanism includes a motor, a synchronous belt, a synchronous pulley, a transmission shaft, an A idler pulley, a flat belt, a B idler pulley, a tensioning mechanism, and a sensor. Among them, the synchronous pulley at the output end of the motor is connected to the synchronous pulley through the synchronous belt. The synchronous pulley is installed in the middle of the transmission shaft. An A idler pulley is installed at each end of the transmission shaft. The two A idler pulleys on both sides are respectively connected to a B idler pulley through a flat belt. A tensioning mechanism is arranged inside the B idler pulley. A sensor is arranged between the two flat belts on both sides.
[0007] Alternatively, preferably, the standard transfer and handling wafer feeding mechanism includes a motor, a synchronous belt, a synchronous pulley, a transmission shaft, an A idler pulley, a flat belt, a B idler pulley, a tensioning mechanism, a sensor, and a coupling. Among them, the synchronous pulley at the output end of the motor is connected to the synchronous pulley through the synchronous belt. The synchronous pulley is installed at one end of a transmission shaft. The other end of this transmission shaft is connected to one end of another transmission shaft through a coupling. An A idler pulley is installed at each end of the two transmission shafts. Each A idler pulley is installed with a B idler pulley through a flat belt. A tensioning mechanism is arranged inside the B idler pulley. Sensors are respectively arranged between a group of flat belts corresponding to the two transmission shafts on both sides.
[0008] Advantages of the present utility model: The structure design is simple and reasonable. By combining the standard conveying and handling mechanism with the vertical cross mechanism, the conveying and handling time can be effectively shortened, the positioning accuracy can be improved, the control adjustment range for printing positioning can be reduced, the printing quality can be improved, time and labor can be saved, the production cost can be saved, and the overall CT ≤ 0.75 s.

[0015] Such as Figure 1As shown in the figure, a vertical cross-transfer printing mechanism for a screen printing machine, the structure of which includes a standard transfer and handling mechanism group, a transfer component C, a transfer printing platform group D, and a clip mechanism E. Among them, several standard transfer and handling mechanism groups along the wafer flow direction are arranged in parallel at intervals. The transfer printing platform group D vertically penetrates the standard transfer and handling mechanism group. Each standard transfer and handling mechanism group is separated by the transfer printing platform group D into a standard transfer and handling wafer feeding mechanism group A on one side and a standard transfer and handling wafer discharging mechanism group B on the other side. The standard transfer and handling wafer feeding mechanism group A and the standard transfer and handling wafer discharging mechanism group B respectively include several standard transfer and handling wafer feeding mechanisms arranged at intervals. A clip mechanism E is provided on the side of the standard transfer and handling wafer feeding mechanism of the standard transfer and handling wafer feeding mechanism group A close to the transfer printing platform group D. The transfer printing platform group D is installed on the transfer component C. The transfer printing platform group D includes several transfer printing platforms 11 arranged at intervals. The transfer component C includes a linear module 13. The transfer printing platform 11 is connected to the linear module 13 through a bearing connecting plate 12.
[0016] As Figure 2 shown, the standard transfer and handling wafer feeding mechanism is a whole-piece type, including a motor 1, a synchronous belt 2, a synchronous pulley 3, a transmission shaft 4, an A idler pulley 5, a flat belt 6, a B idler pulley 7, a tensioning mechanism 8, and a sensor 9. Among them, the synchronous pulley at the output end of the motor 1 is connected to the synchronous pulley 3 through the synchronous belt 2. The synchronous pulley 3 is installed in the middle of the transmission shaft 4. An A idler pulley 5 is installed at each end of the transmission shaft 4. The two A idler pulleys 5 on both sides are respectively connected to a B idler pulley 7 through a flat belt 6. A tensioning mechanism 8 is provided inside the B idler pulley 7. A sensor 9 is provided between the two flat belts 6 on both sides.
[0017] As Figure 3 shown, another standard transfer and handling wafer feeding mechanism is a half-piece type, including a motor 1, a synchronous belt 2, a synchronous pulley 3, a transmission shaft 4, an A idler pulley 5, a flat belt 6, a B idler pulley 7, a tensioning mechanism 8, a sensor 9, and a coupling 10. Among them, the synchronous pulley at the output end of the motor 1 is connected to the synchronous pulley 3 through the synchronous belt 2. The synchronous pulley 3 is installed at one end of a transmission shaft 4. The other end of this transmission shaft 4 is connected to one end of another transmission shaft 4 through a coupling 10. An A idler pulley 5 is installed at each end of the two transmission shafts 4. Each A idler pulley 5 is installed with a B idler pulley 7 through a flat belt 6. A tensioning mechanism 8 is provided inside the B idler pulley 7. A sensor 9 is respectively provided between a group of flat belts 6 corresponding to the two transmission shafts 4 on both sides.
[0018] The standard transfer and handling wafer feeding mechanism is driven by a motor 1. The motor shaft is connected to a synchronous pulley.

[0019] The vertically-transporting printing platform 11 preferably uses a dual-motor to control the roll paper or belt to achieve the conveying and handling in the wafer transport direction, and preferably has a vacuum adsorption function to ensure that the relative positions during the handling and printing of the battery chips remain unchanged.
[0020] Multiple transporting printing platforms 11 are placed on the linear module 13 through the bearing connecting plate 12 according to the transport spacing, and are precisely and quickly transported below multiple printing adjustment platforms.
[0021] The wafer clamping mechanism E is used for aligning the wafers during the wafer transport process.
[0022] During use, the wafers are transported by the standard conveying and handling wafer feeding mechanism group A to the station where the wafer clamping mechanism E is located for aligning the wafers, and then transported to the transporting printing platform group D. At this time, the transfer component C vertically transports the transporting printing platform 11 along the standard conveying and handling mechanism group to the corresponding printing station for printing. At the same time, at the corresponding other station, it goes to the feeding station of the standard conveying and handling wafer feeding mechanism group A to feed the wafers coming from the standard conveying and handling wafer feeding mechanism group A. The station where the printing is completed returns to the original position of the standard conveying and handling wafer feeding mechanism group A, and the wafers are transported out through the standard conveying and handling wafer discharging mechanism group B. At the same time, another printing station performs printing on the incoming materials, and the movement repeats like this.
[0023] All the above components are prior arts, and those skilled in the art can use any models and existing designs that can achieve their corresponding functions.
[0024] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the creative concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
