During PCB printing, a conveying and transfer assembly is needed to transport and transfer the PCB. One type of PCB substrate is... Figure 1 As shown, after the holes are punched, they need to be stacked in a row for easy processing later.

[0003] Existing substrate feeding mechanisms typically use vacuum chucks to pick up and move the substrate. However, when releasing the substrate, the existing vacuum chuck feeding mechanism may encounter issues with the substrate's shape, such as... Figure 1 As shown, the falling substrates are affected by air resistance due to their light weight and large area, resulting in disordered stacking of the substrates in the hopper. There are misalignments, tilting, and even flipping between the substrates, which affects automatic stacking, packaging, and transportation. Utility Model Content

[0004] The purpose of this utility model is to provide a material handling mechanism for unloading printed substrates, so as to solve the problem mentioned in the background art that the existing material handling mechanisms for unloading printed substrates usually use vacuum suction cups to adsorb and move the substrates. However, when the existing vacuum suction cup material handling mechanism releases the substrates, the falling substrates are affected by air resistance due to their light material and large area, resulting in the substrates being stacked in a disordered state in the material bin. There are misalignments, tilting or even flipping between the substrates, which affects automatic stacking, packaging and transportation.

[0005] To solve the above problems, this utility model provides the following technical solution: a material handling mechanism for unloading printing substrate, comprising a frame, a moving part, a storage part, and a limiting part:

[0006] The moving part is located at the top of the frame for transporting the moving substrate. The storage part is located inside the frame. The moving part has a lead screw guide rail c located inside the frame. A lifting moving frame b is vertically slidably arranged inside the lead screw guide rail c.

The limiting part has a limiting frame located inside the frame. A slide is slidably arranged inside the limiting frame. A guide frame is slidably arranged on the side of the slide. The guide frame has an L-shaped structure and abuts against the side of the substrate.

[0007] By adopting the above technical solution, the substrate can be transported and stored. The lead screw guide rail c drives the lifting and moving frame b to move up and down, so that the substrate on the placement plate can be precisely adjusted according to the height detected by the laser sensor. The limiting frame and the guide frame can stabilize the position of the substrate and prevent it from shifting.

[0008] Preferably, the movable part further includes a lead screw guide rail a disposed on the top of the frame, a transverse moving frame slidably disposed inside the lead screw guide rail a, a lead screw guide rail b disposed on the side of the transverse moving frame, a lifting moving frame a slidably disposed vertically inside the lead screw guide rail b, and a vacuum suction cup disposed at the bottom of the lifting moving frame a.

[0009] By adopting the above technical solution, the substrate can be moved in three dimensions with precision. The lead screw guide rail a controls the lateral displacement of the lateral moving frame, and the lead screw guide rail b adjusts the vertical height of the lifting moving frame a, so that the vacuum suction cup can accurately adsorb and transport the substrate.

[0010] Preferably, the storage unit also has a sliding frame disposed at one end of the placement plate and has a through hole, and a limit rod is vertically disposed inside the frame, the limit rod vertically passing through the sliding frame and being vertically slidably connected to the sliding frame.

[0011] By adopting the above technical solution, the stable lifting and lowering of the placement plate can be ensured. The limit rod and the sliding frame cooperate to prevent the placement plate from shifting or shaking during the lifting and lowering process.

[0012] Preferably, the storage unit also has a slide groove formed inside the limiting frame, the slide being embedded in the slide groove and slidably connected to the limiting frame laterally.

[0013] By adopting the above technical solution, the carriage can be adjusted laterally within the slide groove to adapt to substrates of different sizes, thereby improving the versatility of the mechanism.

[0014] Preferably, the storage unit also has a slide bar disposed at one end of the guide frame near the carriage, the slide bar passing laterally through the carriage and slidably connected to the carriage.

[0015] By adopting the above technical solution, the guide frame can be flexibly adjusted according to the width of the substrate through the sliding cooperation between the slide rod and the guide frame, ensuring that the L-shaped structure is always in contact with the side of the substrate.

[0016] Preferably, the storage section also has a fixing bolt a disposed on the top of the slide, the fixing bolt a being threadedly connected to the slide and abutting against the slide rod, and a fixing bolt b disposed on the top of the slide, the fixing bolt b being threadedly connected to the slide and passing through the slide and abutting against the limiting frame.

[0017] By adopting the above technical solution, the position of the slide rod can be locked by fixing bolt a, and the position of the slide bracket in the slide groove can be fixed by fixing bolt b, thus ensuring the stability of the limiting structure.

[0018] Preferably, there are two limiting parts, which are provided on both sides of the frame, and the top of the guide frame is provided with an inclined surface.

[0019] By adopting the above technical solution, the substrate can be symmetrically clamped by the limiting parts on both sides, which improves the positioning accuracy. The inclined surface of the guide frame facilitates the sliding of the substrate and reduces friction and jamming.

[0020] Compared with the prior art, the beneficial effects of this utility model are: by providing a moving part, a storage part and a limiting part, the substrate can be transported and stored. The lead screw guide rail c drives the lifting moving frame b to move up and down, so that the substrate on the placement plate can be precisely adjusted according to the height detected by the laser sensor. The limiting frame and the guide frame can stabilize the position of the substrate and prevent it from shifting. Attached Figure Description

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.

[0029] Example 1

[0030] Please see Figure 2 , Figure 3 and Figure 4 This embodiment provides a technical solution: a material handling mechanism for feeding printed substrate, comprising a frame 1, a moving part 2, a storage part 3, and a limiting part 4.

[0031] The moving part 2 is located at the top of the frame 1 for transporting moving substrates, and the storage part 3 is located inside the frame 1. The moving part 2 has a lead screw guide rail c301 located inside the frame 1. A lifting moving frame b302 is vertically slidably arranged inside the lead screw guide rail c301. A placement plate 303 for placing substrates is located on the top of the lifting moving frame b302. A laser sensor 306 for detecting the stacking height of substrates is located on the side of the lead screw guide rail c301. The laser sensor 306 is a precision sensor that uses laser technology for non-contact measurement and is widely used in distance detection, displacement measurement, contour scanning, positioning control, speed measurement and other scenarios. The above is the prior art, and will not be repeated below. The limiting part 4 is set inside the frame 1. The limiting part 4 has a limiting frame 401 set inside the frame 1. A slide 403 is slidably arranged inside the limiting frame 401. A guide frame 405 is slidably arranged on the side of the slide 403. The guide frame 405 has an L-shaped structure and abuts against the side of the substrate, which can realize the transport and storage of the substrate. The lead screw guide rail c301 drives the lifting moving frame b302 to move up and down, so that the substrate on the placement plate 303 can be precisely adjusted according to the height detected by the laser sensor 306. The limiting frame 401 and the guide frame 405 can stabilize the position of the substrate and prevent it from shifting.

[0032] Example 2

[0033] Please see Figure 4 , Figure 5 and Figure 6 This embodiment provides a technical solution: a material handling mechanism for feeding printed substrate, comprising a frame 1, a moving part 2, a storage part 3, and a limiting part 4.

[0034] A lead screw guide rail a201 is installed at the top of the frame 1. A transverse moving frame 202 is laterally slidable inside the lead screw guide rail a201. A lead screw guide rail b203 is installed on the side of the transverse moving frame 202. A lifting moving frame a204 is vertically slidable inside the lead screw guide rail b203. A vacuum suction cup 205 is installed at the bottom of the lifting moving frame a204. This allows for precise three-dimensional movement of the substrate. The lead screw guide rail a201 controls the transverse displacement of the transverse moving frame 202, and the lead screw guide rail b203 adjusts the vertical height of the lifting moving frame a204, enabling the vacuum suction cup 205 to accurately pick up and transport the substrate. The lead screw guide rail is a commonly used linear motion system, widely used in precision transmission fields such as automated equipment and robotic arms. Its core function is to convert rotary motion into linear motion, ensuring high precision, high rigidity, and low friction transmission. The above is existing technology and will not be elaborated further below.

[0035] A sliding frame 304 with a through hole is provided at one end of the placement plate 303. A limit rod 305 is vertically provided inside the frame 1. The limit rod 305 vertically passes through the sliding frame 304 and is vertically slidably connected to the sliding frame 304, which can ensure the stable lifting and lowering of the placement plate 303. The limit rod 305 cooperates with the sliding frame 304 to prevent the placement plate 303 from shifting or shaking during the lifting and lowering process.

[0036] A slide groove 402 is provided inside the limiting frame 401. The slide 403 is embedded in the slide groove 402 and is laterally slidably connected to the limiting frame 401. This allows the slide 403 to be laterally adjusted within the slide groove 402 to accommodate substrates of different sizes and improve the versatility of the mechanism.

[0037] A slide rod 404 is slidably provided at one end of the guide frame 405 near the slide 403. The slide rod 404 passes laterally through the slide 403 and is slidably connected to the slide 403. The slide rod 404 can slide and cooperate with the guide frame 405, so that the guide frame 405 can be flexibly adjusted according to the width of the substrate, ensuring that the L-shaped structure is always in contact with the side of the substrate.

[0038] A fixing bolt a406 is provided on the top of the slide 403. The fixing bolt a406 is threadedly connected to the slide 403 and abuts against the slide rod 404. A fixing bolt b407 is provided on the top of the slide 403. The fixing bolt b407 is threadedly connected to the slide 403, passes through the slide 403 and abuts against the limit frame 401. The position of the slide rod 404 can be locked by the fixing bolt a406, and the fixing bolt b407 can fix the position of the slide 403 in the slide groove 402 to ensure the stability of the limit structure.

[0039] There are two limiting parts 4, which are located on both sides of the frame 1. The top of the guide frame 405 is provided with an inclined surface. The substrate can be symmetrically clamped by the limiting parts 4 on both sides, which improves the positioning accuracy. The inclined surface of the guide frame 405 facilitates the sliding of the substrate and reduces friction and jamming.

[0040] Working principle: First, the moving part 2 drives the horizontal moving frame 202 and the lifting moving frame a204 to move through the lead screw guide rails a201 and b203, so that the vacuum suction cup 205 can accurately pick up the substrate to be picked up and transport it to the placement plate 303 of the storage part 3. The laser sensor 306 monitors the stacking height of the substrate in real time, and the feedback signal controls the lead screw guide rail c301 to adjust the lifting position of the lifting moving frame b302 to ensure that the substrate is stacked flat. At the same time, the guide frame 405 of the two side limiting parts 4 is adjusted laterally through the slide rod 404 and the slide 403 so that its L-shaped structure is close to the side of the substrate. The fixing bolts a406 and b407 lock the slide rod 404 and the slide 403 respectively to prevent the substrate from shifting. The inclined surface design further guides the substrate to smoothly enter the limiting area. The whole process realizes the automated and precise picking, placing, storage and positioning of the substrate.
