Description

Technical Field

[0001] This utility model relates to a positioning mechanism for 3C product processing, specifically a PCB board pick-up and positioning mechanism. Background Technology

[0002] In the processing of 3C products, it is necessary to adsorb and move the PCB boards. Currently, suction cup holders, because they are only equipped with vacuum nozzles, can only achieve the adsorption function and cannot perform more precise positioning of the PCB boards. When the PCB boards are picked up and moved to the unloading point by a robot, the PCB boards are susceptible to vacuum during movement, and the high speed of the robot movement can easily cause the PCB boards to deviate. To address this, the inventors have developed a PCB board picking and positioning mechanism. Utility Model Content

[0003] The purpose of this utility model is to provide a PCB board suction and positioning mechanism. This PCB board suction and positioning mechanism has the advantages of simple structure and reasonable design. By setting a step on the PCB board positioning rod, the PCB board is in complete contact with the step. At this time, the horizontal accuracy and positional accuracy of the PCB board can be guaranteed, and the motion efficiency is improved. It ensures that the PCB board maintains a high level of horizontal accuracy and positional accuracy during the movement process, thus solving the problems mentioned in the above technical background.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a PCB board suction and positioning mechanism, which includes a suction cup fixing plate, a plurality of PCB board positioning rods are provided on the suction cup fixing plate, each PCB board positioning rod includes a limiting post and an extension angle fixed on the limiting post, the extension angle is fixed at the end of the limiting post away from the suction cup fixing plate, the extension angle is conical, the limiting post is cylindrical, and a workpiece position is formed by sinking down along its length direction on the limiting post, and a step is provided at the end of the limiting post near the extension angle.

[0005] Preferably, the suction cup fixing plate has multiple positioning holes through it, and multiple PCB board positioning rods are respectively set in the multiple positioning holes.

[0006] Preferably, multiple vacuum accordion nozzles are fixed at one end of the suction cup fixing plate near the multiple PCB board positioning rods. The multiple PCB board positioning rods are distributed in a rectangular array, and the multiple vacuum accordion nozzles are all set in the space between the multiple PCB board positioning rods.

[0007] Preferably, each vacuum bellows nozzle includes a fixing head and a nozzle body installed at the end of the fixing head away from the suction cup fixing plate. An air pipe interface is also installed on the fixing head. The fixing heads on multiple vacuum bellows nozzles are all locked into the positioning holes by screws.

[0008] Preferably, there are several workpiece positions, and these workpiece positions are distributed in the circumferential direction of the limiting post, with the depth of the workpiece positions between 0.5mm and 5mm.

[0009] Preferably, the step is arranged in a ring shape, and the outer diameter of the step gradually decreases on the side away from the limiting post. The step is used to contact the PCB board and limit the PCB board.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model provides a PCB board suction and positioning mechanism, which includes a suction cup fixing plate and multiple PCB board positioning rods. The overall structure is simple and reasonably designed. Each PCB board positioning rod includes a limiting post and an extension angle fixed to the limiting post. An extension angle is fixed at the end of the limiting post away from the suction cup fixing plate. The extension angle is conical. A step is provided at the end of the limiting post near the extension angle. When suctioning the PCB board, the extension angle is first inserted into the positioning hole on the PCB board for initial positioning. Then, the vacuum bellows nozzle is opened to vacuum and the PCB board is suctioned by the vacuum bellows nozzle, causing the PCB board to rise. During this process, the PCB board gradually rises to the step, so that the PCB board finally makes full contact with the step. At this time, the horizontal and positional accuracy of the PCB board can be guaranteed, and the motion efficiency is improved, ensuring that the PCB board maintains high horizontal and positional accuracy throughout the movement.

[0012] 2. The limiting post in this utility model is cylindrical, and a workpiece position is formed by sinking down along its length direction on the limiting post. Several workpiece positions are provided and distributed in the circumferential direction of the limiting post. The workpiece positions can make the tightening of the limiting post more convenient and improve the assembly efficiency of the limiting post. Attached Figure Description

The plurality of PCB board positioning rods 3 are arranged in a rectangular array, and the plurality of vacuum bellows nozzles 2 are all arranged in the space between the plurality of PCB board positioning rods 3.

[0026] Please see Figure 2 Multiple positioning holes 11 are provided through the suction cup fixing plate 1. The positioning holes 11 have two specifications, which are used to limit the vacuum bellows nozzle 2 and the PCB board positioning rod 3 respectively.

[0027] Please see Figure 3 Each vacuum bellows nozzle 2 includes a fixed head 21 and a nozzle body 22 installed at the end of the fixed head 21 away from the suction cup fixing plate 1. An air pipe interface 23 is also installed on the fixed head 21. The fixed heads 21 on multiple vacuum bellows nozzles 2 are all locked in the positioning holes 11 by screws, which are used to lock the fixed head 21 and the limiting post 31 respectively. The working principle of multiple vacuum bellows nozzles 2 is the existing technology, and will not be described in detail here.

[0028] Please see Figure 4 Each PCB positioning rod 3 includes a limiting post 31 and an extension angle 32 fixed on the limiting post 31. An extension angle 32 is fixed at the end of the limiting post 31 away from the suction cup fixing plate 1. The extension angle 32 is conical. The limiting post 31 is cylindrical. A workpiece position 311 is formed by sinking down along the length direction of the limiting post 31. A step 312 is provided at the end of the limiting post 31 near the extension angle 32.

[0029] Please see Figure 5 Several workpiece positions 311 are provided, and these workpiece positions 311 are distributed in the circumferential direction of the limiting post 31. The depth of the workpiece positions 311 is between 0.5mm and 5mm. By using the workpiece positions 311, when tightening the limiting post 31 onto the suction cup fixing plate 1 with tools such as wrenches, the friction between the tool and the limiting post 31 can be increased, making the tightening of the limiting post 31 more convenient and improving the assembly efficiency of the limiting post 31. In addition, the step 312 is arranged in a ring shape, and the outer diameter of the step 312 gradually decreases on the side away from the limiting post 31. The step 312 is used to contact the PCB board 4 and limit the PCB board 4.

[0030] Please see Figure 6 Multiple PCB board positioning rods 3 are respectively set in multiple positioning holes 11. In this embodiment, the limiting posts 31 on the multiple PCB board positioning rods 3 are all locked in the positioning holes 11 by screws.

[0031] Please see Figure 7 The PCB board suction and positioning mechanism is used for positioning the PCB board 4. The PCB board 4 is provided with multiple locking holes 41, which correspond to the positions of multiple PCB board positioning rods 3. During operation, when the PCB board 4 is suctioned, the PCB board 4 approaches the multiple PCB board positioning rods 3 from bottom to top. Therefore, multiple extension angles 32 will be inserted into the multiple locking holes 41 for initial positioning. Then, multiple vacuum bellows nozzles 2 are opened to vacuum, and the multiple vacuum bellows nozzles 2 are used to suction the PCB board 4, which drives the PCB board 4 to rise. During the rising process, the PCB board 4 gradually rises to the multiple steps 312, so that the PCB board 4 finally makes complete contact with the multiple steps 312. At this time, the horizontal accuracy and positional accuracy of the PCB board 4 can be guaranteed, and the motion efficiency is improved, ensuring that the PCB board 4 maintains a high level of horizontal accuracy and positional accuracy during the movement.
