Description

Technical Field

[0001] This invention belongs to the field of thin plate separation technology, specifically relating to a thin plate stacking rack with a separation feeding mechanism. Background Technology

[0002] Potentiometers and circuit boards contain many thin-plate components, such as carbon sheets, which are crucial components in potentiometers and are formed by stamping thin carbon sheets. Before stamping, these carbon sheet stamping plates often need to be stacked using a stacking rack. Traditional thin-plate stacking racks use simple flat stacking, but because there is almost no air between the plates, the adhesion between them is very strong. When the suction cup gripper picks them up, it often grabs multiple plates at once, resulting in a large number of scrapped plates during the carbon sheet stamping process.

[0003] To address this, patent specification CN218114398U discloses a thin plate stacking rack for easy separation and feeding. The rack includes a movable base, a tray, a hinge, a lifting mechanism, a first limiting plate, a second limiting plate, and an air blowing mechanism. The front ends of the movable base and the tray are rotatably connected by the hinge. A lifting mechanism is installed between the movable base and the tray. The first limiting plate is symmetrically installed on the movable base, and the second limiting plate is symmetrically installed on the tray near the hinge. An air blowing mechanism is installed on the outer side of the second limiting plate. When separation and feeding are required, the lifting mechanism can be used to quickly switch to inclined stacking, and the air blowing mechanism can be used to blow air onto the lower end area of ​​the uppermost thin plate workpiece in the inclined state, separating the upper thin plate workpiece from the lower thin plate workpiece. This ensures that the suction cup gripper only picks up one thin plate workpiece at a time, avoiding scrap losses.

[0004] However, this type of thin-plate stacking rack has shortcomings in use. First, it relies solely on upward air blowing for separation, and the separation effect needs further improvement. Second, its layout is not reasonable, as it does not reserve space for electrical boxes and air pump boxes, requiring additional mobile equipment to load them, which reduces its ease of use. Therefore, the existing thin-plate stacking rack structure needs to be optimized and improved. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned problems existing in the conventional technology and to provide a thin plate stacking rack with a separating feeding mechanism.

[0006] To achieve the above-mentioned technical objectives and effects, the present invention is implemented through the following technical solution:

[0007] A thin plate stacking rack with a separating feeding mechanism includes a movable carriage, a material support plate, and corner brackets. The front ends of the movable carriage and the material support plate are rotatably connected by a first hinge structure. A storage section is provided in the middle of the movable carriage. Movable rollers are installed at the four corners of the lower side of the movable carriage. An electric scissor lift frame is installed in the storage section. A second hinge structure is installed between the top crossbeam of the electric scissor lift frame and the middle of the bottom side of the material support plate. An electrical box and an air pump box are respectively installed on the front and rear sides of the bottom side of the material support plate near the left and right ends. Multiple sets of support blocks are symmetrically arranged on the bottom side of the material support plate near the front and rear ends. Two sets of corner brackets are symmetrically installed on the upper side of the material support plate near the front and rear ends. A drive screw and a guide rod are respectively installed in the two corner brackets in the same set. A separating feeding mechanism is installed between the drive screw and the guide rod.

[0008] Furthermore, in the aforementioned sheet stacking rack with a separate feeding mechanism, the bottom surface of the moving roller is lower than the bottom surface of the storage section, and the two moving rollers near the rear end of the moving plate are provided with a self-locking mechanism to facilitate locking the stopping position.

[0009] Furthermore, in the aforementioned thin plate stacking rack with a separate feeding mechanism, the height of the support block is greater than the height of the electrical box and the air pump box. When the material support plate is rotated to a horizontal state under the restriction of the first hinge structure, the bottom surface of the support block just abuts against the upper side of the moving vehicle plate. A safety anti-collision gap is left between the electrical box and the air pump box and the upper side of the moving vehicle plate, respectively.

[0010] Furthermore, in the aforementioned sheet stacking rack with a separate feeding mechanism, when the material support plate is rotated to a horizontal state under the constraint of the first hinge structure, the electric scissor lift can be stored and hidden in the storage section.

[0011] Furthermore, in the aforementioned thin plate stacking rack with a separating feeding mechanism, the front end of the moving plate extends to form a first extending convex plate, and the front end of the material support plate extends to form a second extending convex plate. A plurality of buffer damping support rods are embedded in the first extending convex plate, and a third hinge structure is installed between the top end of the buffer damping support rod and the bottom side of the second extending convex plate.

[0012] Furthermore, in the above-mentioned thin plate stacking rack with a separating feeding mechanism, the corner bracket is a right-angle plate structure, and four corner brackets together form a rectangular thin plate stacking area. The length of the rectangular thin plate stacking area is 0.5 to 1 cm longer than the length of the thin plate to be stacked. The corner bracket has a dial groove extending along the length of the support plate on the support plate parallel to the width direction of the support plate.

[0013] Furthermore, in the aforementioned sheet stacking rack with a separating feeding mechanism, the separating feeding mechanism includes an air knife box, a driving slider, a driven slider, a dial wheel mounting block, a dial wheel, and a dial wheel motor. A rotating shaft passing through the rear of the air knife box connects the driving slider and the driven slider. The front of the air knife box has an inner cavity, and the front end of the air knife box has a strip-shaped air outlet communicating with the inner cavity. A dial wheel mounting block is fixed to the inner side of each of the driving slider and the driven slider. A dial wheel extending into the feeding groove and a dial wheel motor for driving the dial wheel to rotate are installed in the dial wheel mounting block. The dial wheel is made of flexible wear-resistant silicone material. The dial wheel protrudes outward relative to the feeding groove. When the dial wheel is rotated, it can cause the sheet in contact with the dial wheel to tend to move with the dial wheel.

[0014] Furthermore, in the aforementioned thin plate stacking rack with a separating feeding mechanism, the driving slider has a screw groove that cooperates with the driving screw, and the driven slider has a guide groove that cooperates with the guide rod; the driven slider is provided with a first extended plate perpendicularly near the air knife box, and the rear of the air knife box is provided with a second extended plate perpendicularly near the driven slider; a fastening screw is screwed into the first extended plate, and the fastening screw locks the position of the air knife box relative to the rotating shaft by screwing inward to abut against the second extended plate.

[0015] Furthermore, in the aforementioned sheet stacking rack with a separate feeding mechanism, the electrical box is used to provide power to each electrical component, and the air pump box is used to provide pulsed airflow to the two air knife boxes.

[0016] Furthermore, the aforementioned sheet metal stacking rack with a separating feeding mechanism also includes a controller, which is connected to the electric scissor lift telescopic frame, the drive screw, the dial motor, the electrical box, and the air pump box.

[0017] The beneficial effects of this invention are:

[0018] 1. The thin plate stacking rack provided by this invention has a separation feeding mechanism. This mechanism is rationally designed. Based on the tilting of the thin plates, which creates a certain misalignment between the upper and lower layers, it is equipped with air knife boxes with adjustable air blowing direction and dial wheels with adjustable rotation direction on both the front and rear sides of the thin plates. For thin plates with harder materials, a method of "blowing upwards and turning upwards" at one end and "blowing downwards and turning downwards" at the other end can be used to "flip" the top layer of thin plates, facilitating suction cup picking. For thin plates with softer materials, a method of "blowing upwards and turning upwards" at one end and "blowing upwards and turning upwards" at the other end can be used to increase the probability of separation between the upper and lower layers of thin plates, facilitating suction cup picking. This ensures that the suction cup gripper picks up only one thin plate workpiece at a time, avoiding scrap losses.

[0019] 2. The present invention adds a horizontally distributed electric scissor lift frame between the moving platform and the pallet. The electric scissor lift frame is used to drive the pallet to rotate at a certain angle. The layout is reasonable. The area on both sides of the bottom of the pallet located on the electric scissor lift frame can be used as the installation area for the electrical box and air pump box, so that the electrical box and air pump box do not need to be loaded by additional moving equipment, which makes it more convenient to use.

[0020] 3. The present invention adds a buffer damping support rod between the front end of the moving vehicle plate and the material support plate. The design of the buffer damping support rod makes the material support plate more stable during the flipping process, and avoids wear between the stacked thin plates and the corner frame caused by the flipping vibration.

[0021] Of course, any product implementing this invention does not necessarily need to achieve all of the above advantages at the same time. Attached Figure Description

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1-8 As shown, this embodiment provides a thin plate stacking rack with a separate feeding mechanism, including a movable carriage 1, a support plate 2, and a corner rack 14. The front ends of the movable carriage 1 and the support plate 2 are rotatably connected by a first hinge structure 3. A storage section 4 is provided in the middle of the movable carriage 1, and movable rollers 5 are installed at the four corners of the lower side of the movable carriage 1. An electric scissor lift telescopic frame 6 is installed in the storage section 4, and a second hinge structure 7 is installed between the top crossbeam of the electric scissor lift telescopic frame 6 and the middle of the bottom side of the support plate 2. An electrical box 8 and an air pump box 9 are respectively installed on the bottom side of the support plate 2 on the front and rear sides of the second hinge structure 7. Multiple sets of support blocks 10 are symmetrically arranged on the bottom side of the support plate 2 near the left and right ends. Two sets of corner brackets 14 are symmetrically installed on the upper side of the pallet material 2 near the front and rear ends. A drive screw 15 and a guide rod 16 are respectively installed in the two corner brackets 14 in the same set. A separation feeding mechanism 17 is installed between the drive screw 15 and the guide rod 16.

[0035] In this embodiment, the bottom surface of the movable roller 5 is lower than the bottom surface of the storage part 4, and the two movable rollers 5 near the rear end of the movable vehicle plate 1 are provided with a self-locking mechanism to facilitate locking the parking position.

[0036] In this embodiment, the height of the support block 10 is greater than the height of the electrical box 8 and the air pump box 9. When the material support plate 2 is rotated to a horizontal state under the restriction of the first hinge structure 3, the bottom surface of the support block 10 just abuts against the upper side of the moving plate 1. A safety anti-collision gap is left between the electrical box 8 and the air pump box 9 and the upper side of the moving plate, respectively.

[0037] In this embodiment, when the material support plate 2 rotates to a horizontal state under the restriction of the first hinge structure 3, the electric scissor lift 6 can be stored and hidden in the storage part 4. The design of the second hinge structure 7 makes the electric scissor lift 6 remain in a vertical state during the lifting process.

[0038] In this embodiment, the front end of the mobile platform 1 extends to form a first extending protrusion 11, and the front end of the material support plate 2 extends to form a second extending protrusion 12. A plurality of buffer damping support rods 13 are embedded in the first extending protrusion 11, and a third hinge structure 19 is installed between the top end of the buffer damping support rod 13 and the bottom side of the second extending protrusion 12.

[0039] In this embodiment, the corner bracket 14 is a right-angle plate structure, and the four corner brackets 14 together form a rectangular thin plate stacking area. The length of the rectangular thin plate stacking area is 0.5 to 1 cm longer than the length of the thin plate to be stacked. The corner bracket 14 has a dial groove 18 extending along the length of the support plate on the support plate parallel to the width direction of the support plate 2.

[0040] In this embodiment, the separating feeding mechanism 17 includes an air knife box 171, a driving slider 172, a driven slider 173, a dial wheel mounting block 177, a dial wheel 178, and a dial wheel motor 179. A rotating shaft passing through the rear of the air knife box 171 connects the driving slider 172 and the driven slider 173. The front of the air knife box 171 has an inner cavity, and the front end of the air knife box 171 has a strip-shaped air outlet communicating with the inner cavity. The bottom side of the air knife box 171 has an air inlet pipe mounting hole communicating with the inner cavity. The dial wheel mounting block 177 is fixed to the inner side of each of the driving slider 172 and the driven slider 173. The dial wheel 178 extending into the feeding groove 18 and the dial wheel motor 179 for driving the dial wheel 178 to rotate are installed in the dial wheel mounting block 177. The dial 178 is made of flexible and wear-resistant silicone material. The dial 178 protrudes outward relative to the feed groove 18. When the dial 178 is flipped, it can cause the thin plate in contact with the dial 178 to tend to move with the dial 178.

[0041] In this embodiment, the drive slider 172 has a screw groove that mates with the drive screw 15, and the driven slider 173 has a guide groove that mates with the guide rod 16. The driven slider 173 is vertically provided with a first extension plate 174 near the air knife box 171, and the rear of the air knife box 171 is vertically provided with a second extension plate 175 near the driven slider 173. A fastening screw 176 is screwed into the first extension plate 174. The fastening screw 176 locks the position of the air knife box 171 relative to the rotating shaft by screwing it inward to abut against the second extension plate 175.

[0042] In this embodiment, the electrical box 8 is used to provide power to each electrical component, and the air pump box 9 is used to provide pulsed airflow to the two air knife boxes.

[0043] In this embodiment, a controller is also included, which is connected to the electric scissor lift frame 6, the drive screw 15, the dial motor 179, the electrical box 8, and the air pump box 9.

[0044] The first specific application of this embodiment is as follows: This embodiment provides a thin plate stacking rack with a separating feeding mechanism. The separating feeding mechanism 17 is reasonably designed. Based on the tilting of the thin plates, which causes a certain misalignment between the upper and lower thin plates, it is equipped with an air knife box 171 with adjustable air blowing direction and a dial wheel 178 with adjustable rotation direction on both the front and rear sides of the thin plates. For thin plates with harder materials, one end can be "blown upward + turned upward" and the other end can be "blown downward + turned downward" to make the uppermost thin plate "flipped" for easy suction cup picking. For thin plates with softer materials, one end can be "blown upward + turned upward" and the other end can be "blown upward + turned upward" to increase the probability of separation between the upper and lower thin plates, making it easier for the suction cup to pick up the material. This ensures that the suction cup gripper picks up only one thin plate workpiece at a time, avoiding scrap losses.

[0045] The second specific application of this embodiment is as follows: A laterally distributed electric scissor lift frame 6 is added between the moving platform 1 and the pallet 2. The electric scissor lift frame 6 drives the pallet 2 to rotate at a certain angle. This layout is reasonable, and the area on both sides of the bottom of the pallet 2, located on either side of the electric scissor lift frame 6, can serve as the installation area for the electrical box 8 and the air pump box 9. This eliminates the need for additional mobile equipment to load the electrical box 8 and the air pump box 9, improving ease of use. A buffer damping support rod 13 is added between the front ends of the moving platform 1 and the pallet 2. The design of the buffer damping support rod 13 ensures high stability of the pallet during rotation, preventing wear between the stacked thin plates and the corner rack 14 caused by rotation vibration.

[0046] The preferred embodiments of the present invention disclosed above are merely illustrative of the invention. These preferred embodiments do not exhaustively describe all details, nor do they limit the invention to specific implementations. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the invention, thereby enabling those skilled in the art to better understand and utilize the invention.
