Description

Technical Field

[0001] This utility model relates to the field of dispensing technology, specifically to a dispensing positioning mechanism. Background Technology

[0002] With the continuous development of society, mobile phones, tablets and other electronic devices have become essential communication tools for every household, and their annual output is constantly increasing. PCB boards are required for mobile phones, tablets and other electronic products. In the PCB board production process, after the PCB board is positioned by a positioning mechanism, the components on the surface of the PCB board are protected by glue dispensing machine.

[0003] During dispensing positioning, the PCB board is conveyed to the positioning mechanism via a conveyor line. The positioning mechanism uses limiting posts on the surface of the PCB board to limit and position the through holes. Then, the dispensing machine dispenses the glue. However, since the PCB board is only positioned by the limiting posts, it is prone to displacement and shaking during the dispensing process due to the impact of the glue. When the PCB board shakes or shifts, the dispensing position is prone to deviation, affecting the quality of the glue dispensing. Utility Model Content

[0004] The purpose of this invention is to provide a dispensing positioning mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A dispensing positioning mechanism includes: a transport component, a conveyor frame and a dispensing component disposed on one side of the transport component, a fixing frame installed on the inner wall of the conveyor frame, and further includes:

[0007] The positioning mechanism is located above the fixed frame. The positioning mechanism includes a positioning plate located above the fixed frame. Limiting posts are fixedly installed on the top surface of the positioning plate. The positioning mechanism is used to position the PCB board.

[0008] The fixing mechanism is located above the fixing frame. The fixing mechanism includes a baffle located above the fixing frame, and an arc-shaped rod is slidably installed through the lower side of the baffle. The fixing mechanism is used to fix the PCB board.

[0009] Preferably, a lifting cylinder is fixedly installed on the top surface of the fixed frame, the upper end of the lifting cylinder is fixedly connected to the bottom surface of the positioning plate, and two limit posts are provided.

[0010] Preferably, two limiting rods are fixedly installed on the bottom surface of the positioning plate, and the lower ends of the two limiting rods slide through the top surface of the fixing frame and extend to the bottom of the fixing frame. A circular plate is fixedly installed on the lower ends of the two limiting rods respectively.

[0011] Preferably, multiple support columns are fixedly installed on the top surface of the positioning plate, and two stop cylinders are fixedly installed on the bottom surface of one end of the positioning plate. A stop column is fixedly installed on the upper end of the stop cylinder, and the upper end of the stop column slides through the bottom surface of the positioning plate and extends to the top of the positioning plate.

[0012] Preferably, a mounting bracket is fixedly installed on the top surface of the mounting frame, and two fixing frames and two baffles are installed on the top surface of the mounting bracket.

[0013] Preferably, two fixing blocks are fixedly installed on the side of the positioning plate, a connecting frame is fixedly installed on the side of the fixing blocks, and a rotating shaft is fixedly installed through the side of the baffle. The two ends of the rotating shaft are rotatably connected to the inner wall of the connecting frame through bearing seats.

[0014] Preferably, one end of the arc-shaped rod is fixedly connected to the bottom surface of the positioning plate, and the other end of the arc-shaped rod is fixedly installed with a circular plate.

[0015] Preferably, an adjusting column is fixedly installed on the lower side of the baffle, the outer wall of the adjusting column is slidably connected to the inner wall of the fixed frame, and a circular plate is fixedly installed on the other end of the adjusting column.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention uses a stop post to contact one side of the PCB board, causing the positioning plate to move upward, which in turn moves the connecting frame and the baffle. The other end of the baffle moves the adjusting post within the fixed frame, causing one end of the adjusting post and the baffle to rotate at a certain angle, and the other end of the baffle to rotate at the same angle. The upper side of the baffle contacts and presses against the side of the PCB board. The baffle and the stop post work together to press and fix both sides of the PCB board. When applying glue to the PCB board, the PCB board is less likely to shift or shake, thereby improving the accuracy and quality of the glue application.

[0018] The PCB board is positioned by limiting the position of the PCB board through the through holes, preventing it from shifting. The stop cylinder moves the stop column, which then stops the PCB board, ensuring it stops accurately above the positioning plate. The lifting cylinder moves the positioning plate, which in turn moves the limit rod, which limits the positioning plate, making its movement more stable and further ensuring the stability of the PCB board.

[0029] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0030] like Figures 1-5 As shown, this application provides a dispensing positioning mechanism, including: a transport assembly 1, a conveyor frame 101 and a dispensing assembly 102 are provided on one side of the transport assembly 1, a fixing frame 103 is installed on the inner wall of the conveyor frame 101, and further includes:

[0031] Positioning mechanism 2 is located above the fixed frame 103. Positioning mechanism 2 includes a positioning plate 202 located above the fixed frame 103. Limiting posts 206 are fixedly installed on the top surface of the positioning plate 202. Positioning mechanism 2 is used to position the PCB board.

[0032] Specifically, such as Figures 1-5As shown, a lifting cylinder 201 is fixedly installed on the top surface of the fixed frame 103. The upper end of the lifting cylinder 201 is fixedly connected to the bottom surface of the positioning plate 202. Two limit posts 206 are provided.

[0033] In this embodiment: the lifting cylinder 201 drives the positioning plate 202 to move, and the limiting post 206 positions the PCB board.

[0034] Specifically, such as Figures 1-5 As shown, two limiting rods 203 are fixedly installed on the bottom surface of the positioning plate 202. The lower ends of the two limiting rods 203 slide through the top surface of the fixing frame 103 and extend to the bottom of the fixing frame 103. A circular plate 204 is fixedly installed on the lower ends of the two limiting rods 203 respectively.

[0035] In this embodiment, the positioning plate 202 is limited by the setting limit rod 203, so that the positioning plate 202 moves more stably.

[0036] Specifically, such as Figures 1-5 As shown, multiple support columns 205 are fixedly installed on the top surface of the positioning plate 202, and two stop cylinders 207 are fixedly installed on the bottom surface of one end of the positioning plate 202. A stop column 208 is fixedly installed on the upper end of the stop cylinder 207, and the upper end of the stop column 208 slides through the bottom surface of the positioning plate 202 and extends to the top of the positioning plate 202.

[0037] In this embodiment: the stop cylinder 207 drives the stop column 208 to move, thereby blocking the PCB board from passing through, and the support column 205 supports the PCB board.

[0038] The fixing mechanism 3 is located above the fixing frame 103. The fixing mechanism 3 includes a baffle 306 located above the fixing frame 103. An arc-shaped rod 307 is slidably installed through the lower side of the baffle 306. The fixing mechanism 3 is used to fix the PCB board.

[0039] Specifically, such as Figures 1-5 As shown, a mounting bracket 301 is fixedly installed on the top surface of the mounting bracket 103, and two fixing frames 302 are installed on the top surface of the mounting bracket 301, and two baffles 306 are provided.

[0040] In this embodiment, the mounting bracket 301 supports the fixing frame 302.

[0041] Specifically, such as Figures 1-5 As shown, two fixing blocks 303 are fixedly installed on the side of the positioning plate 202, a connecting frame 304 is fixedly installed on the side of the fixing block 303, and a rotating shaft 305 is fixedly installed through the side of the baffle 306. The two ends of the rotating shaft 305 are rotatably connected to the inner wall of the connecting frame 304 through bearing seats.

[0042] In this embodiment: the connecting frame 304 is fixed by the fixed block 303, and the PCB board is pressed and fixed by the baffle 306.

[0043] Specifically, such as Figures 1-5 As shown, one end of the arc-shaped rod 307 is fixedly connected to the bottom surface of the positioning plate 202, and the other end of the arc-shaped rod 307 is fixedly installed with a circular plate 308.

[0044] In this embodiment, the baffle 306 is limited by the arc-shaped rod 307, making the rotation of the baffle 306 more stable.

[0045] Specifically, such as Figures 1-5 As shown, an adjusting column 309 is fixedly installed on the lower side of the baffle 306. The outer wall of the adjusting column 309 is slidably connected to the inner wall of the fixed frame 302. A circular plate 310 is fixedly installed on the other end of the adjusting column 309.

[0046] In this embodiment: through the set adjustment column 309 and fixed frame 302, when the baffle 306 and adjustment column 309 move, the adjustment column 309 moves on the inner wall of the fixed frame 302.

[0047] The specific solution is as follows: After the PCB board passes inspection, the transport assembly 1 transports the PCB board onto the conveyor frame 101. When the PCB board is positioned at the positioning plate 202, the stop cylinder 207 drives the stop column 208 to block the PCB board, and the lifting cylinder 201 drives the positioning plate 202 to move upward. The positioning plate 202 drives the support column 205 to support the bottom surface of the PCB board. At the same time, the limiting column 206 is inserted into the through hole of the PCB board to position the PCB board. During the upward movement of the positioning plate 202, it drives the connecting frame 304 and the baffle 306 to move. The other end of the baffle 306 drives the adjusting column 309 to move within the inner wall of the fixed frame 302, so that the adjusting column 309 and the baffle 306 move together. When one end of the baffle 306 rotates a certain angle, the other end of the baffle 306 also rotates a certain angle. The upper side of the baffle 306 contacts and presses against the side of the PCB board. The baffle 306 and the stop post 208 work together to press and fix the two sides of the PCB board, making it less likely for the PCB board to shift or shake. After the dispensing assembly 102 dispenses glue onto the PCB board, the lifting cylinder 201 drives the positioning plate 202 and the PCB board to move downwards. The PCB board contacts the conveyor frame 101, and at the same time, the baffle 306 returns to its original position and is in a horizontal state. The limit post 206 moves out of the through hole of the PCB board, and the stop cylinder 207 drives the stop post 208 to move downwards. The PCB board is then conveyed from the conveyor frame 101 to the next processing position.
