[0023] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.
[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0025] Secondly, the "embodiment" referred to herein refers to a specific feature, structure or characteristic that can be included in at least one implementation of the utility model. The "in one embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. Example
[0026] Reference Figure 1-Figure 4 This embodiment provides a multi-station printing device for a printed circuit board, comprising a frame 1, a printing mechanism 2 is arranged on one side of the top of the frame 1, and a feeding mechanism 3 is arranged on the other side of the top of the frame 1; the feeding mechanism 3 comprises a fixing plate 4 fixed to the top of the frame 1, the fixing plate 4 is provided with a through hole 1 5, a through hole 2 6 and a through hole 3 7, the through hole 1 5, the through hole 2 6 and the through hole 3 7 form a T shape, and the through hole 3 7 is located in the middle of the printing mechanism 2, as shown in FIG. Figure 1As shown, the through hole three 7 is arranged along the width direction of the frame 1, the extensions of the through hole one 5 and the through hole two 6 overlap, and the through hole one 5 and the through hole three 7 are arranged along the length direction of the frame 1;
[0027] The feeding mechanism 3 also includes a placing plate 1 8 and a placing plate 2 9, which are used to place circuit boards. A connecting shaft 10 is fixed to the bottom of the placing plate 1 8, and the connecting shaft 10 passes through the through hole 1 5. Under the action of the driving mechanism 1, the connecting shaft 10 moves along the through hole 1 5 and the through hole 3 7;
[0028] A connecting shaft 2 is fixed at the bottom of the placing plate 2 9, and the connecting shaft 2 passes through the through hole 2 6. Under the action of the driving mechanism 2, the connecting shaft 10 moves along the through hole 2 6 and the through hole 3 7;
[0029] In this embodiment, when in use, by controlling the driving mechanism 1 and the driving mechanism 2, the placing plate 1 8 and the placing plate 2 9 are successively in the stroke of the printing mechanism 2. Under the premise of only one printing mechanism 2, the circuit boards on the two placing plates are alternately printed, which reduces the loading and unloading time of the circuit boards and improves the processing efficiency; through the driving mechanism 1, the connecting shaft 10 and the placing plate 8 are moved along the through hole 1 5 and the through hole 3 7. When moving on the through hole 1 5, the placing plate 1 8 moves from the side of the printing mechanism 2 to the middle position of the printing mechanism 2. When moving on the through hole 3 7, the placing plate 1 8 moves from the outside to the inside of the printing mechanism 2, and then the printing mechanism 2 prints the circuit board on the placing plate 8. During the printing process, the circuit board on the placing plate 2 9 can be taken and placed. After the printing of the circuit board on the placing plate 8 is completed, the placing plate 1 8 is restored to the initial position, and then the driving mechanism 2 is operated to move the placing plate 2 9 to the printing position.
[0030] As a preferred solution of the utility model, the connection between the through hole 1 5 and the through hole 3 7 and the connection between the through hole 2 6 and the through hole 3 7 are both chamfered. Figure 1 and Figure 2 As shown, during the movement of the connecting shaft 10 and the connecting shaft 2, the chamfering process can improve the smoothness of movement between different through holes and prevent jamming.
[0031] As a preferred solution of the utility model, the driving mechanism 1 includes a rotating shaft 11 rotatably connected to the frame 1, the rotating shaft 11 is fixed with one end of a driving rod 12, the driving rod 12 is provided with a long hole 1, the connecting shaft 10 passes through the long hole 1, and the bottom end of the rotating shaft 11 is a motor 13, such as Figure 2As shown, the rotating shaft 11 is installed in the area surrounded by the through hole 15 and the through hole 37. When the motor 13 drives the rotating shaft 11 and the driving rod 12 to rotate, since the rotating shaft 11 is installed in the area surrounded by the through hole 15 and the through hole 37, the driving rod 12 always generates a thrust on the connecting shaft 10, causing it to move along the through hole 15 and the through hole 37. Through the above arrangement, the two-way action of the placing plate 8 can be achieved using a single power, which is lower in cost.
[0032] As a preferred solution of the utility model, the driving mechanism 2 includes a rotating shaft 2 rotatably connected to the frame 1, the rotating shaft 2 is fixed with one end of the driving rod 2, the driving rod 2 is provided with a long hole 2, the connecting shaft 2 passes through the long hole 2, and the bottom end of the rotating shaft 2 is a motor 2, such as Figure 2 As shown, the rotating shaft 2 is installed in the area surrounded by the through hole 2 6 and the through hole 3 7. When the motor 2 drives the rotating shaft 2 and the driving rod 2 to rotate, since the rotating shaft 2 is installed in the area surrounded by the through hole 2 6 and the through hole 3 7, the driving rod 2 always generates a thrust on the connecting shaft 2, causing it to move along the through hole 2 6 and the through hole 3 7. Through the above arrangement, the bidirectional action of the placing plate 2 9 can be achieved using a single power, which is lower in cost.
[0033] As a preferred solution of the utility model, the fixed plate 4 is fixed with a track 14, the track 14 is slidably connected with a slider 15 and a slider 2, the slider 15 is fixed with a track 2 16, the track 2 16 is slidably connected with a slider 3 17, the connecting shaft 10 is fixedly connected with the slider 3 17; the slider 2 is fixed with a track 3, the track 3 is slidably connected with a slider 4, the connecting shaft 2 is fixedly connected with the slider 4, such as Figure 2 and Figure 3 As shown, track 1 14 is arranged along the length direction of the frame 1, track 2 16 and track 3 are both arranged along the width direction of the frame 1, and the connecting shaft 10 drives the slider 3 17 to move when moving along the through hole, and the slider 3 17 can only slide along track 1 14 or track 2 16, and the connecting shaft 10 is fixedly connected to the slider 3 17. Under the premise that the slider 3 17 cannot rotate, the connecting shaft 10 and the placement plate 1 8 will not rotate either, and similarly, the placement plate 2 9 will not rotate either.
[0034] As a preferred solution of the utility model, a limiting component 1 and a limiting component 2 are provided on the fixed plate 4, the limiting component 1 includes a fixed shaft 18 fixed on the fixed plate 4, a baffle 19 rotatably mounted on the fixed shaft 18 through a torsion spring, and a limiting block 20 for fixing on the fixed plate 4; the limiting component 2 includes a fixed shaft 2 fixed on the fixed plate 4, a baffle 2 rotatably mounted on the fixed shaft 2 through a torsion spring, and a limiting block 2 for fixing on the fixed plate 4; under the action of the torsion spring, the limiting block 120 contacts with the baffle 19, the limiting block 2 contacts with the baffle 2, the limiting plate 1 faces the through hole 15, and the limiting plate 2 faces the through hole 26; Figure 2 As shown, when the connecting shaft 10 moves from the through hole 15 to the through hole 3 7, under the action of the thrust, the baffle 2 will rotate around the fixed shaft 2. After the baffle 2 is separated from the connecting shaft 10, under the action of the torsion spring, the baffle 2 contacts the limit block 2 again. When the connecting shaft 10 moves from the through hole 3 7 to the through hole 5, due to the action of the limit block 20, the baffle 2 cannot rotate toward the placement plate 2 9. The position of the baffle 2 makes the connecting shaft 10 can only move to the through hole 5. The movement of the connecting shaft 2 is the same as the above process and will not be explained in detail.
[0035] As a preferred solution of the utility model, both the placement plate 1 8 and the placement plate 2 9 are provided with a positioning mechanism, and the positioning mechanism includes four positioning plates 21, two of which can slide, such as Figure 1 As shown, through the above arrangement, circuit boards of various sizes can be accommodated, the circuit boards can be positioned, and the practicality can be improved.
[0036] As a preferred solution of the utility model, the connecting shaft 10 and the connecting shaft 2 are both provided with rollers 22, and the rollers 22 are clamped on the fixing plate 4, such as Figure 4 As shown, the height of the placement plate 1 8 and the placement plate 2 9 is prevented from changing.
[0037] The operation process of the utility model is as follows: Figure 1 As shown, drive mechanism 1 or drive mechanism 2 is operated to move the placement plate loaded with circuit boards into the stroke of printing mechanism 2, and then printing is performed. During the printing process, another placement plate is used to take and place circuit boards. After printing is completed, this placement plate is moved out to the initial position, and then the other placement plate is moved to the printing position. The operations are performed alternately to reduce the loading and unloading time and improve the processing efficiency.
[0038] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
