Description

Technical Field

[0001] This utility model relates to the field of PCB board production, specifically a panel loading mechanism for a double-sided simultaneous screen printing machine. Background Technology

[0002] A PCB, also known as a printed circuit board, is a support structure for electronic components and a provider of electrical interconnections between them. In the printed circuit board (PCB) industry, vertical double-sided simultaneous screen printing has its unique characteristics and advantages. However, in the past, the surface roughening process before screen printing used mechanical roughening methods. This method provided good surface strength, good resistance to contact and scratches, but in recent years, chemical surface roughening processes have emerged. These processes suffer from drawbacks such as surface etching roughening, low mechanical strength, poor contact resistance, and a high and noticeable scratch rate, leading to a high defect rate on the panel surface. In past vertical double-sided screen printing equipment, the traditional panel loading mechanism, which operates from the middle of the panel, is no longer suitable for current processes. This design effectively avoids these problems. Summary of the Invention

[0003] The purpose of this invention is to provide a panel loading mechanism for a double-sided simultaneous screen printing machine to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A panel loading mechanism for a double-sided simultaneous screen printing machine includes a panel socket and a square alignment frame. The panel socket has several equally spaced insertion holes at its top, into which several panel bodies are inserted. The square alignment frame is arranged parallel to one side of the panel socket, and a fixing frame is fixedly mounted on its top. First propulsion cylinders are fixedly mounted at both ends of the fixing frame. A mounting plate is mounted on the telescopic end of the first propulsion cylinder. A second propulsion cylinder is fixedly mounted at the center of the right end of the mounting plate. The telescopic end of the second propulsion cylinder is connected to a third propulsion cylinder via an L-shaped connecting plate. The telescopic end of the third propulsion cylinder is connected to a pusher head via an L-shaped connecting plate. The pusher head is used to move each panel body.

[0005] Preferably, adjustment holes are provided at both ends of the bottom of the fixing frame where it connects to the square guide frame.

[0006] Preferably, the pusher head is provided with several rolling rings.

[0007] Compared with the prior art, the advantages of this utility model are: 1. Small size, and the installation method is space installation, which does not increase the operating space.

[0008] 2. It completely avoids contact scratches on the circuit and copper surface caused by solder mask ink, which can greatly improve the product qualification rate and reduce the rework rate of panel assembly.

[0009] 3. Low maintenance costs; operates in conjunction with the main control equipment; extremely low failure rate; few spare parts required. 4. This utility model can realize the automatic board feeding action when vertical double-sided screen printing of PCB board, which can replace the original contact design. At the same time, it can avoid the defects of copper surface and circuit scratches in this process. It is simple to operate. The control system can be nested in the original host action system by using interface circuit, without modifying the original system concept. Attached Figure Description

[0014] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been presented in the various embodiments of this utility model to enable the reader to better understand this application. However, the technical solutions claimed in this application can be implemented even without these technical details and with various changes and modifications based on the following embodiments.

[0016] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] See Figure 1-3In this embodiment of the utility model, a panel loading mechanism for a double-sided simultaneous screen printing machine includes a panel socket 1 and a square alignment frame 3. The panel socket 1 has several insertion holes at equal intervals on its top. Several panel bodies 2 are inserted into the insertion holes. The insertion holes facilitate the insertion of the panel bodies 2 and enable loading and insertion between the panel socket 1 and the panel bodies 2.

[0018] The square alignment frame 3 is arranged parallel to one side of the panel socket 1. A fixing frame 5 is fixedly installed on the top of the square alignment frame 3. A first push cylinder 6 is fixedly installed at both ends of the fixing frame 5. A mounting plate is installed at the telescopic end of the first push cylinder 6. A second push cylinder 7 is fixedly installed at the center of the right end of the mounting plate. The telescopic end of the second push cylinder 7 is connected to a third push cylinder 8 through an L-shaped connecting plate. The telescopic end of the third push cylinder 8 is connected to a push head 9 through an L-shaped connecting plate. The push head 9 is used to push each panel body 2 to move. The symmetrically arranged first push cylinder 6 drives the mounting plate to adjust its left and right movement. With the cooperation of the second push cylinder 7 and the third push cylinder 8, the push head 9 can be adjusted to move forward and backward, thereby enabling the movement and loading of each panel body 2.

[0019] See Figure 1 In one embodiment of this utility model, adjustment holes 4 are provided at the front and rear ends of the connection between the bottom of the fixing frame 5 and the square alignment frame 3. The setting of adjustment holes 4 can facilitate the fixing and installation of the fixing frame 5 and the square alignment frame 3, as well as the angle adjustment of the fixing frame 5.

[0020] See Figure 1 In one embodiment of this utility model, the pusher head 9 is provided with a plurality of free rolling rings. The free rolling rings can facilitate the pusher head 9 to protect the panel body 2 during the pushing process.

[0021] Working principle: This utility model uses a first propulsion cylinder 6 to push the mounting plate to move left and right. The mounting plate simultaneously drives a second propulsion cylinder 7 to move left and right, and the second propulsion cylinder 7 pushes a third propulsion cylinder 8 to move back and forth. Together with the third propulsion cylinder 8, the pusher head 9 is moved adaptively. This allows the panel body 2 inserted into the panel socket 1 to be pushed and loaded, which facilitates the installation of panels with vertical screen printing on both sides of the PCB manufacturing process. Through timing control, the contact position of the pusher arm is moved from the middle to the edge of the panel to meet the requirements of the actual use environment, effectively avoiding contact scratches and damage to the panel graphic.

[0022] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
