Description

Technical Field

[0001] The utility model relates to a double-line linkage transplanting mechanism of a screen printing machine, belonging to the technical field of screen printing machines. Background Art

[0002] In the existing technology, screen printing mainly adopts the following two methods: one is to use standard transmission to transfer to a turntable structure driven by a DD motor, and then transfer it to the printing station by rotating the turntable at a certain angle; the other is to use standard transmission to transfer to a linear motor cross printing platform, and then drive the printing platform to the printing station through the linear motor.

[0003] The aforementioned methods all share long waiting times, resulting in poor time utilization. Furthermore, none offer transfer platform rotation or UVW adjustment capabilities. Printing relies solely on camera vision to adjust the print head, limiting rotation angle and position. Furthermore, compatibility with wafers of varying sizes is poor. Furthermore, larger wafers require a larger turntable mechanism, further reducing overall line efficiency and increasing printing times. CT scans are difficult to improve, typically exceeding 0.8 seconds. Maintenance is also difficult, resulting in low productivity. Utility Model Content

[0004] The utility model provides a double-line linkage transplanting mechanism for a screen printing machine, which aims to overcome the above-mentioned shortcomings of the prior art and shorten the printing time of the entire line.

[0005] The technical solution of the utility model is as follows: a double-line linkage transfer mechanism of a screen printing machine, whose structure includes a film feeding mechanism, a transfer mechanism, a rotary reversing mechanism, a UVW platform, a transmission printing platform and a film discharge mechanism, wherein the transmission printing platforms are evenly spaced and arranged in a row, the bottom of the transmission printing platform is connected to the UVW platform, the bottom of the UVW platform is connected to the rotary reversing mechanism, all the rotary reversing mechanisms are connected to the same transfer mechanism, printing head mechanisms are arranged at intervals above the transmission printing platform, and corresponding film feeding mechanisms and film discharge mechanisms are vertically arranged on both sides of the transmission printing platforms in a row, and the corresponding film feeding mechanisms and film discharge mechanisms are arranged in a row, and a clamping mechanism is provided on the side of the film feeding mechanism close to the transmission printing platform.

[0006] Preferably, there are five transfer printing platforms, and the corresponding film feed mechanisms and film discharge mechanisms are arranged in two rows. The spacing between the two printing head mechanisms is equal to the spacing between the two transfer printing platforms separated by one transfer printing platform. There are three printing head mechanisms, which are respectively arranged above the first, third, and fifth transfer printing platforms when they are not moving. During operation, the film feed mechanism transports the silicon wafer, and the clamping mechanism corrects it before it enters the transfer printing platform. When the five transfer printing platforms are not in operation, they correspond to five initial positions, among which the printing head mechanisms are arranged above the first, third, and fifth positions. After operation begins, the first and third transfer printing platforms move to the bottom of the first and third position printing head mechanisms to print the silicon wafers. At the same time, the film feed mechanism transports the silicon wafers to the second and fourth transfer printing platforms. After printing is completed, the first and third transfer printing platforms return to their original positions, and the film discharge mechanism transports the silicon wafers away. The second and fourth transfer printing platforms then move to the bottom of the third and fifth position printing head mechanisms to print the silicon wafers. This cycle repeats.

[0007] The advantages of this utility model include a simple and rational structural design, a dual-line linkage transfer mechanism, and the ability to design the specific number of mechanisms according to production needs. This effectively reduces waiting time for each component, shortens printing time, and improves overall line CT. It also addresses issues such as compatibility between full and half wafers, large wafer feed angles, inaccurate wafer placement, and lengthy paper roll replacement times on the printing platform. It offers convenient maintenance, high work efficiency, and time and labor savings, ultimately reducing production costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] The present invention will be further described in detail below with reference to the embodiments and specific implementation methods.

[0011] like Figure 1 As shown, a double-line linkage transfer mechanism of a screen printing machine includes a film feeding mechanism 1, a transfer mechanism 3, a rotary reversing mechanism 4, a UVW platform 5, a transmission and printing platform 6 and a film discharge mechanism 7, wherein the transmission and printing platforms 6 are evenly spaced and arranged in a row. The bottom of the transmission and printing platform 6 is connected to the UVW platform 5, and the bottom of the UVW platform 5 is connected to the rotary reversing mechanism 4. All the rotary reversing mechanisms 4 are connected to the same transfer mechanism 3. Printing head mechanisms (not shown) are arranged at intervals above the transmission and printing platforms 6. Corresponding film feeding mechanisms 1 and film discharge mechanisms 7 are vertically arranged on both sides of the transmission and printing platforms 6 in a row, and the corresponding film feeding mechanisms 1 and film discharge mechanisms 7 are arranged in a row.

[0012] A film clamping mechanism 2 is provided on the side of the film feeding mechanism 1 close to the transmission printing platform 6 .

[0013] As an example, Figure 1 The figure shows a whole-piece 2-line 4-head device, with a total of five transmission and printing platforms 6, and two rows of corresponding film feeding mechanisms 1 and film discharging mechanisms 7. The distance between the two printing head mechanisms is equal to the distance between the two transmission and printing platforms 6 separated by one transmission and printing platform 6. There are three printing head mechanisms, which are respectively arranged above the first, third, and fifth transmission and printing platforms 6 when they are not moving.

[0014] During operation, the film feeding mechanism 1 transports the silicon wafer, which is then aligned by the film clamping mechanism 2 before entering the transmission and printing table 6. The five transmission and printing platforms 6 correspond to five initial positions when not in operation, among which a printing head mechanism is arranged above the first, third and fifth positions. After the start of operation, the first and third transmission and printing platforms 6 move to the bottom of the first and third position printing head mechanisms for silicon wafer printing. At the same time, the film feeding mechanism 1 transports the silicon wafer to the second and fourth transmission and printing platforms 6. After printing is completed, the first and third transmission and printing platforms 6 move to their original positions and the film discharging mechanism 7 transports the silicon wafer away. The second and fourth transmission and printing platforms 6 move to the bottom of the third and fifth position printing head mechanisms for silicon wafer printing, and the cycle repeats.

[0015] The embodiment also includes 1 line 2 heads, 2 lines 3 heads, 1 line multiple heads, 2 lines multiple heads, etc. The increase or decrease of each mechanism can be carried out according to actual production.

[0016] The wafer feed mechanism 1 and wafer discharge mechanism 7 are used to transport silicon wafers onto and remove them from the transport printing platform 6. The rotary reversing mechanism 4 implements the rotational reversal of the upper structure. The UVW adjustment platform adjusts the UVW of the transport printing platform 6. The wafer clamping mechanism 2 is used to align the silicon wafers, and the transfer mechanism 3 drives the upper structure in linear motion. The transport printing platform 6 can be a full-wafer or half-wafer type, and can be equipped with a single motor or dual motors. The specific structures of these mechanisms are not within the scope of protection of this application.

[0017] The components described above are all prior art, and those skilled in the art can use any model and existing design that can achieve their corresponding functions.

[0018] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, which all fall within the scope of protection of the present invention.
