Description

Technical Field

[0001] This utility model relates to the field of circuit board processing technology, and in particular to a transfer holder for circuit boards. Background Technology

[0002] During circuit board processing, circuit boards are usually transferred using conveyor belts. To avoid contaminating the copper layer of the circuit board during transfer, a pad or thin plastic plate is often placed underneath it. This method avoids the aforementioned problem. However, because there is a necessary positioning between the pad or plastic plate and the circuit board, relative movement between the circuit board and the pad can easily occur during circuit board rotation and transfer, which is detrimental to circuit board processing and quality assurance. Utility Model Content

[0003] This utility model provides a circuit board transfer stand to overcome the shortcomings of the prior art. It can position the circuit board to prevent relative movement between the circuit board and the lower support component, and has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted:

[0005] A circuit board transfer holder includes a base plate with multiple mounting posts. A transfer plate is mounted on the upper end of each mounting post, and the transfer plate is screwed onto the mounting posts. A circuit board is placed on the transfer plate. Limiting plates are provided around the circuit board, and limiting screws are provided at both ends of each limiting plate. Multiple guide holes are formed on the transfer plate, and the limiting screws pass through these guide holes. Side top plates are welded to the limiting plates, and limiting protrusions are formed on the inner ends of the side top plates. The inner wall of the side top plates acts on the outer wall of the circuit board, and the limiting protrusions limit the upper side of the circuit board. A lower limiting plate is mounted on the lower end of each pair of limiting screws, and the lower limiting plate is located below the transfer plate. The side top plates and limiting plates act on the side walls of the circuit board, thereby achieving the purpose of positioning the circuit board. Furthermore, the limiting protrusions limit the upper side of the circuit board, improving the limiting effect.

[0006] Furthermore, the upper wall of the limiting protrusion is inclined, and the inner end of the inclined surface extends downward. This design can reduce the weight of the entire transfer seat.

[0007] Furthermore, an inner top plate is welded to the lower end of the limiting plate, and a pair of guide rods are installed on the inner top plate. The outer ends of each pair of guide rods are connected to a fixed end seat by threads. The fixed end seat is installed on the transfer plate by screws. A spring is sleeved on the guide rod. The spring is located between the fixed end seat and the inner top plate. The spring can make the limiting plate move inward, thereby limiting the side wall of the circuit board through the limiting plate.

[0008] Furthermore, a pair of vertical plates are welded to the lower limiting plate. The outer ends of the vertical plates have oblique holes, through which inner push rods pass. Four pressing recesses are installed on the transfer plate, with the vertical sections of the pressing recesses extending onto the transfer plate. The inner push rods are located at the lower ends of the pressing recesses. The outer ends of the oblique holes extend upwards at an angle. These oblique holes are designed to allow the limiting plate to move outwards when the circuit board is placed. When the circuit board is placed, an active driving mechanism such as a cylinder moves the pressing recesses downwards, causing the limiting plate to move outwards, thus facilitating the placement of the circuit board on the transfer plate. When the pressing force of the pressing recesses disappears, the limiting plate will then re-limit the circuit board.

[0009] Furthermore, to prevent the limiting plate from damaging the circuit board, a soft buffer layer is provided on the inner wall of the limiting plate.

[0010] The advantages of the above technical solution are:

[0011] This invention can position the circuit board to prevent relative movement between the circuit board and the transfer board, and also facilitates the placement of the circuit board. Attached Figure Description

[0012] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will provide a further detailed description of this utility model in conjunction with the accompanying drawings.

[0014] Figure 2 A magnified view of point A is shown.

[0015] Figure 3 A three-dimensional structure of one embodiment is shown. Figure 2 .

[0016] Figure 4 A magnified view of point B is shown. Detailed Implementation

[0017] like Figures 1-4 As shown, a circuit board transfer holder includes a base plate 1, on which multiple mounting posts 10 are mounted. A transfer plate 2 is provided at the upper end of the mounting posts 10, and the transfer plate 2 is mounted on the mounting posts 10 by screws 11.

[0018] The circuit board is placed on the transfer plate 2. Limiting plates 22 are provided around the circuit board. The inner wall of the limiting plate 22 is provided with a soft buffer layer. Limiting screws 21 are provided at both ends of the limiting plate 22. Multiple guide holes 20 are opened on the transfer plate 2. The limiting screws 21 are inserted into the guide holes 20. A side top plate 23 is welded on the limiting plate 22. A limiting protrusion 24 is formed on the inner end of the side top plate 23. The upper wall of the limiting protrusion 24 is inclined, and the inner end of the inclined surface extends downward. The inner wall of the side top plate 23 acts on the outer wall of the circuit board. The limiting protrusion 24 is used for limiting the upper side of the circuit board. A limiting lower plate 33 is installed at the lower end of each pair of limiting screws 21. The limiting lower plate 33 is located on the lower side of the transfer plate 2.

[0019] The lower end of the limiting plate 33 is welded with an inner top plate 31. A pair of guide rods 30 are threaded through the inner top plate 31. The outer ends of each pair of guide rods 30 are connected to a fixed end seat 3 by threads. The fixed end seat 3 is installed on the transfer plate 2 by screws. A spring 32 is sleeved on the guide rod 30. The spring 32 is located between the fixed end seat 3 and the inner top plate 31.

[0020] A pair of vertical plates 34 are welded on the lower limiting plate 33. An oblique hole 35 is provided on the outer end of the vertical plate 34. An inner push rod 36 is inserted through the oblique hole 35. Four pressing recesses 37 are inserted through the transfer plate 2. The vertical section of the pressing recess 37 is inserted through the transfer plate 2. The inner push rod 36 is located at the lower end of the pressing recess 37. The outer end of the oblique hole 35 extends upward at an angle.

[0021] In application, the transfer plate is located directly below the circuit board unloading area. Above the circuit board unloading area can be a suction cup with lifting function. The upper end of the suction cup is connected to a lifting cylinder, which is mounted on a movable horizontal plate. One end of the movable horizontal plate is connected to a drive component such as a lead screw. When the circuit board is in place, the suction cup moves onto the circuit board under the drive of the lifting cylinder, and then the suction cup adsorbs the circuit board. Then, it moves upward under the drive of the lifting cylinder, and then the linear mechanism such as the lead screw drives the circuit board to move, transferring the circuit board directly above the transfer plate 2. Then, the circuit board moves downward. In order to enable the limiting plate 22 to move outward when the circuit board moves downward, four extensions are also required at the lower end of the movable end of the lifting cylinder. The arm, with a pressing foot at its outer end, allows the pressing foot to act on the pressing recess 37 when the lifting cylinder moves the suction cup downwards. This causes the pressing recess 37 to move downwards, and the movement of the pressing recess 37 causes the inner push rod 36 to act on the oblique hole 35, thus moving the lower limiting plate 33 outwards. At this time, the spring 32 is compressed, and the limiting protrusion 24 moves out from directly below the circuit board. Then, the suction cup moves the circuit board onto the transfer plate 2 and cancels the suction of the circuit board. Afterwards, the suction cup returns to its original position. Then, because the pressing recess 37 loses its downward pressure, it moves upwards, while the limiting protrusion 24 moves inwards under the action of the spring 32, positioning the circuit board. When the circuit board is transferred to the designated position, it can also be removed in the above manner.

[0022] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
