Description

Technical Field

[0001] This utility model relates to the field of plate take-up and untake-down machine technology, specifically to a plate take-up and untake-down machine frame positioning mechanism. Background Technology

[0002] A board take-up and unload machine is an automated piece of equipment primarily used in the manufacturing process of printed circuit boards (PCBs) to automatically collect, store, release, and transport PCBs, thereby improving production efficiency and reducing manual intervention. Board take-up and unload machines typically use plastic frames (material frames) to protect the circuit boards or electronic components, preventing them from falling off or being damaged due to vibration or collision during transportation or use. A positioning mechanism is usually required in the board take-up and unload machine to position the plastic frames.

[0003] For example, the utility model patent with application publication number CN119637442A discloses a plate receiving and releasing machine. This device integrates the plate receiving and releasing functions into one unit. It can select to receive or release plates according to the user's needs, making it flexible to use and serving two purposes in one device. This reduces production costs and enables automatic replacement of the plate receiving and releasing frames, improving the efficiency of frame replacement and reducing labor costs and labor intensity.

[0004] However, when positioning the material frame, the device clamps the material frame with positioning plates on both sides. This positioning mechanism can only position the material frame (plastic frame) from the left and right sides, and cannot position the front and back sides of the material frame (plastic frame) well. The positioning effect is limited (the positioning accuracy is insufficient) and cannot meet the usage requirements well. Utility Model Content

[0005] The purpose of this utility model is to provide a frame positioning mechanism for a board take-up and put-out machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A frame positioning mechanism for a plate take-up and unload machine includes: a pair of mounting frames, each mounting frame having a pair of fixing mechanisms installed on it, the fixing mechanisms being distributed on the front and rear sides of the mounting frames; each fixing mechanism includes a fixing base plate fixed to the mounting frame via a connecting seat, a fixing electric cylinder mounted on the fixing base plate, the telescopic end of the fixing electric cylinder passing through the fixing base plate and having a fixing push plate installed thereon, fixing angle plates mounted at both the upper and lower ends of the fixing push plate, a fixing groove being formed in the middle of the fixing angle plate, the fixing groove having an angle of 90°; and the included angle between the fixing base plate and the mounting frame being 45°.

[0007] As a preferred embodiment, a pair of auxiliary rotating rollers are rotatably installed between the fixed angle plates, and the pair of auxiliary rotating rollers are distributed on both sides of the fixed groove.

[0008] As a preferred embodiment, the auxiliary roller is a rubber roller.

[0009] As a preferred embodiment, each of the fixed base plates is equipped with a pair of fixed sleeves, and the fixed push plate is equipped with a fixed guide rod, which is slidably inserted into the fixed sleeve.

[0010] As a preferred embodiment, the mounting frame includes a fixed crossbeam, a first support leg, and a second support leg. The first support leg is installed at the lower end of the fixed crossbeam, and the second support leg is installed on the inner side of the fixed crossbeam. The first and second support legs are distributed in the front and rear halves of the fixed crossbeam.

[0011] As a preferred embodiment, the connecting seat includes a connecting part for fixing to the mounting frame and a fixing part for mounting the fixing plate, wherein the included angle between the connecting part and the fixing part is 45°.

[0012] Compared with existing technologies, the advantages of this invention are as follows: By using a fixed electric cylinder on the rear fixing mechanism to move the fixed push plate, the fixed corner plates on both sides are fitted onto the rear side of the frame. Similarly, by using a fixed electric cylinder on the front fixing mechanism to move the front fixed push plate, the corresponding fixed corner plates are fitted onto the front side of the frame. This allows for positioning of the frame from four directions (front, back, left, and right), improving the positioning effect and better meeting usage requirements. This invention has a reasonable structure and can simultaneously position the frame from multiple directions, improving the positioning effect and better meeting usage needs.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example: Please refer to Figures 1-5 A frame positioning mechanism for a board take-up and drop-out machine includes: a pair of mounting frames, each mounting frame having a pair of fixing mechanisms 4, the fixing mechanisms 4 being distributed on the front and rear sides of the mounting frames; each fixing mechanism 4 includes a fixing base plate 41 fixed to the mounting frame via a connecting seat, a fixing electric cylinder 44 mounted on the fixing base plate 41, the telescopic end of the fixing electric cylinder 44 passing through the fixing base plate 41 and having a fixing push plate 42 mounted thereon, fixing angle plates 43 mounted at both the upper and lower ends of the fixing push plate 42, a fixing groove 431 being formed in the middle of the fixing angle plate 43, the fixing groove 431 having an angle of 90°; the included angle between the fixing base plate 41 and the mounting frame being 45°; in this embodiment, a pair of auxiliary rotating rollers 47 are rotatably mounted between the fixing angle plates 43, the pair of auxiliary rotating rollers 47 being distributed on both sides of the fixing groove 431; the connecting seat includes a connecting part 3 for fixing to the mounting frame and a fixing part 31 for mounting the fixing base plate 41, the included angle between the connecting part 3 and the fixing part 31 being 45°. In this embodiment, the plastic frame 2 is placed on a trolley, and the trolley moves the plastic frame 2 to the designated position (board receiving position or board releasing position) of the board receiving and releasing machine. Then, the plastic frame 2 can be positioned by the fixing mechanism.

[0017] The working principle of this utility model is as follows: In specific use, by pushing the trolley into the designated position of the board take-up and put-down machine, the fixed electric cylinder 44 on the rear fixing mechanism 4 pushes the fixed push plate 42 to move, so that the pair of fixed corner plates 43 on the rear side are fitted onto the rear side of the frame 2. Immediately afterwards, the fixed electric cylinder 44 on the front fixing mechanism 4 extends, pushing the pair of fixed push plates 42 on the front side to move, so that the corresponding fixed corner plates 43 are fitted onto the front side of the frame 2. With the cooperation of the pair of fixed corner plates 43 on the rear side, the positioning work of the frame 2 can be completed from four directions: front, back, left, and right, which can improve the positioning effect of the frame 2 and thus better meet the usage requirements.

[0018] To prevent the auxiliary rotating roller 47 from damaging the rubber frame 2 during positioning, the auxiliary rotating roller 47 is a rubber roller. By setting the auxiliary rotating roller 47, the rubber frame 2 can be easily inserted into the fixing groove 431 of the fixing angle plate 43, thereby facilitating the positioning work.

[0019] As a further embodiment, each of the fixed base plates 41 is equipped with a pair of fixed sleeves 45, and the fixed push plate 42 is equipped with a fixed guide rod 46, which is slidably inserted into the fixed sleeve 45. By setting the fixed sleeves 45 in conjunction with the fixed guide rods 46, the stability of the movement of the fixed push plate 42 can be improved.

[0020] As a further embodiment, the mounting frame includes a fixed crossbeam 1, a first support leg 12, and a second support leg 11. The first support leg 12 is installed at the lower end of the fixed crossbeam 1, and the second support leg 11 is installed on the inner side of the fixed crossbeam 1. The first support leg 12 and the second support leg 11 are distributed in the front and rear halves of the fixed crossbeam 1. In this embodiment, the rear fixing mechanism 4 is installed on the second support leg 11. By installing the fixing mechanism 4 on the second support leg 11, the drive stroke of the rear fixing electric cylinder 44 can be effectively shortened, thereby facilitating the selection of a smaller fixing electric cylinder 44 for installation and reducing the space occupied by the fixing mechanism 4 in the internal space of the trolley. The front fixing mechanism 4 is installed on the fixed crossbeam 1 and the first support leg 12, which allows the fixing mechanism 4 to be further away from the center position, thereby effectively reducing the possibility of collisions when the trolley moves, thus better meeting the usage requirements.
