Description

Technical Field

[0001] This utility model relates to the field of material transportation technology, and in particular to a sheet material feeding device. Background Technology

[0002] Many workpieces are initially placed in plate-shaped trays upon arrival. In automated production, one step involves placing these trays, loaded with workpieces, onto the robotic arm's pick-up station. Currently, this is mainly done manually by workers. This method not only results in low feeding efficiency but also low positioning accuracy, significantly increasing the difficulty for the robotic arm to pick up the workpieces.

[0003] Therefore, it is necessary to develop a sheet material feeding device to realize the mechanized feeding operation of sheet material trays, thereby improving the feeding efficiency and feeding positioning accuracy of sheet material trays.

[0004] The information disclosed in this background section is included only to enhance the understanding of the context of this disclosure, and therefore may contain information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0005] One objective of this invention is to provide a sheet material feeding device that enables mechanized feeding of sheet material trays, thereby improving the feeding efficiency and positioning accuracy of sheet material trays.

[0006] To achieve the above objectives, this utility model provides a sheet metal feeding device, comprising:

[0007] A layered silo, wherein the layered silo is provided with a plurality of discharge slots spaced apart from top to bottom; wherein each discharge slot is used to insert a plate-shaped material tray;

[0008] A lifting platform is used to drive the layered silo to move up and down.

[0009] A feeding guide mechanism includes a first guide plate and a second guide plate disposed opposite to each other, and an elastic pushing component located on the first guide plate; wherein the elastic pushing component is used to push the plate-shaped tray to abut against the second guide plate to achieve pushing and positioning of the plate-shaped tray;

[0010] A material pulling mechanism is located between the two guide plates and is used to pull the plate-shaped material tray outward from the layered hopper along the material feeding guide mechanism.

[0011] Optionally, the discharge port of the layered silo is provided with an upper and lower plug-in setting to restrict each of the plate-shaped material trays from detaching from the baffle plate of the layered silo.

[0012] Optionally, the plate-shaped tray is provided with a T-shaped groove for the material stop plate to be inserted.

[0013] Optionally, the material pulling mechanism includes a hook cylinder for engaging with the T-slot, and a hook linear drive mechanism for driving the hook cylinder closer to and away from the layered hopper.

[0014] Optionally, the elastic pushing assembly includes a pushing slide seat slidably connected to the first guide plate, a pushing spring located on the side of the pushing slide seat away from the second guide plate and driving the pushing slide seat to slide toward the second guide plate, and a pushing roller rotatably mounted on the pushing slide seat to cooperate with the second guide plate to laterally clamp the plate-shaped material tray.

[0015] Optionally, both the first guide plate and the second guide plate are provided with a supporting horizontal surface that supports the plate-shaped material tray upwards. Each supporting horizontal surface is provided with a retaining boss on the side away from the other supporting horizontal surface to prevent the plate-shaped material tray from disengaging from the feeding guide mechanism. The pushing roller is used to cooperate with the retaining boss of the second guide plate to push and position the plate-shaped material tray.

[0016] Optionally, both the first guide plate and the second guide plate are provided with elastic pressing components for pressing the plate-shaped material tray downwards in conjunction with the corresponding supporting horizontal surface.

[0017] Optionally, the elastic pressing assembly includes a pressing sliding seat that is slidably connected to the corresponding guide plate, a tension spring that drives the pressing sliding seat to slide downward, and a pressing roller mounted on the pressing sliding seat and cooperating with the supporting horizontal surface to press the plate-shaped material tray downward.

[0018] Optionally, both the first guide plate and the second guide plate are provided with a linkage adsorption mechanism on the inner side of the end away from the layered silo for adsorbing and positioning the plate-shaped material tray.

[0019] Optionally, the linkage adsorption mechanism includes:

[0020] A vertical sliding arm is slidably connected to the corresponding guide plate; wherein, the bottom of the vertical sliding arm is provided with a guide slope.

[0021] A suction nozzle is mounted on the top surface of the vertical sliding arm;

[0022] A linkage roller is rotatably mounted on the hook-claw cylinder;

[0023] in,

[0024] When the linkage roller disengages from the guide slope, the top surface of the suction nozzle is lower than the bottom surface of the plate-shaped material tray;

[0025] When the linkage roller abuts against the guide slope and is driven away from the layered hopper by the hook linear drive mechanism, the top surface of the suction nozzle moves upward to be in close contact with the bottom surface of the plate-shaped material tray.

[0026] The beneficial effects of this utility model are as follows: It provides a sheet metal feeding device, the working process of which is as follows:

[0027] ① Feeding: Manually load the plate-shaped material trays into the feeding slots of each layer of the tiered silo, and then place the tiered silo on the lifting platform;

[0028] ② Lifting platform descends: Start the lifting platform to move the layered silo downwards until the bottom discharge chute is aligned with the feeding guide mechanism.

[0029] ③ Pulling material: The pulling mechanism starts and first pulls the plate-shaped material tray out of the layered silo, and then moves it along the feeding guide mechanism to the picking station of the picking robot for picking up the material;

[0030] It should be noted that during the material pulling process, the positioning (longitudinal positioning) of the plate-shaped material tray along the pulling direction is determined by the material pulling mechanism. When the longitudinal positioning of the plate-shaped material tray reaches the preset position, the material pulling mechanism stops pulling.

[0031] The positioning of the plate-shaped material tray perpendicular to the pulling direction (lateral positioning) is achieved by the second guide plate and the elastic pushing component. During the entire movement of the plate-shaped material tray, the elastic pushing component always pushes the plate-shaped material tray to abut against the second guide plate, thereby achieving the lateral positioning of the plate-shaped material tray.

[0032] ④ Lifting platform descends: After the material is picked up, the lifting platform descends one level to prepare for the next material release.

[0033] Therefore, the plate feeding device provided by this utility model can realize the mechanized feeding operation of plate-shaped material trays, thereby improving the feeding efficiency and feeding positioning accuracy of plate-shaped material trays. Attached Figure Description

[0056] See Figures 1-3 This utility model provides a sheet material feeding device, including a layered hopper 1, a lifting platform 2, a feeding guide mechanism 3, and a pulling mechanism 4.

[0057] The layered silo 1 is provided with a plurality of discharge slots 101 spaced apart from top to bottom; wherein each discharge slot 101 is used to insert a plate-shaped tray 100. The lifting platform 2 is used to drive the layered silo 1 to move up and down. The feeding guide mechanism 3 includes a first guide plate 3a and a second guide plate 3b arranged opposite to each other, and an elastic pushing component 5 located on the first guide plate 3a; wherein the elastic pushing component 5 is used to push the plate-shaped tray 100 to abut against the second guide plate 3b, so as to achieve pushing and positioning of the plate-shaped tray 100. The pulling mechanism 4 is located between the two guide plates and is used to pull the plate-shaped tray 100 outward from the layered silo 1 along the feeding guide mechanism 3.

[0058] The sheet metal feeding device provided in this embodiment operates as follows:

[0059] ① Feeding: The manual first loads the plate-shaped material tray 100 into the feeding slots 101 of each layer of the layered silo 1, and then places the layered silo 1 on the lifting platform 2.

[0060] ② Lifting platform 2 descends: Start lifting platform 2 to make the layered silo 1 move downward as a whole until the bottom material discharge trough 101 is aligned with the material feeding guide mechanism 3.

[0061] ③ Pulling material: The pulling mechanism 4 is started, first pulling the plate-shaped material tray 100 out of the layered silo 1, and then moving it along the feeding guide mechanism 3 to the picking station of the picking robot for picking up material;

[0062] It should be noted that during the material pulling process, the positioning (longitudinal positioning) of the plate-shaped material tray 100 along the material pulling direction is determined by the material pulling mechanism 4. When the longitudinal positioning of the plate-shaped material tray 100 reaches the preset position, the material pulling mechanism 4 stops pulling.

[0063] The positioning (lateral positioning) of the plate-shaped material tray 100 perpendicular to the material pulling direction is achieved by the second guide plate 3b and the elastic pushing component 5. During the entire movement of the plate-shaped material tray 100, the elastic pushing component 5 always pushes the plate-shaped material tray 100 to abut against the second guide plate 3b, thereby achieving the lateral positioning of the plate-shaped material tray 100.

[0064] ④ Lifting platform 2 descends: After the material is picked up, lifting platform 2 descends another level to prepare for the next material release.

[0065] Therefore, the plate feeding device provided by this utility model can realize the mechanized feeding operation of the plate-shaped material tray 100, thereby improving the feeding efficiency and feeding positioning accuracy of the plate-shaped material tray 100.

[0066] In this embodiment, the discharge port of the layered silo 1 is provided with an up-and-down insertion mechanism to prevent each of the plate-shaped trays 100 from detaching from the baffle plate 102 of the layered silo 1. The plate-shaped tray 100 is provided with a T-shaped groove 100a for the baffle plate 102 to be inserted. After the plate-shaped tray 100 is inserted into the discharge trough 101, the baffle plate 102 is then inserted into the T-shaped groove 100a, which can prevent the plate-shaped tray 100 from detaching from the layered silo 1, so as to facilitate the transportation and transfer of the layered silo 1.

[0067] In this embodiment, the material pulling mechanism 4 includes a hook cylinder 401 for engaging with the T-shaped groove 100a, and a hook linear drive mechanism 402 for driving the hook cylinder 401 to approach and move away from the layered hopper 1.

[0068] The elastic pushing assembly 5 includes a pushing slide seat 501 slidably connected to the first guide plate 3a, a pushing spring located on the side of the pushing slide seat 501 away from the second guide plate 3b and driving the pushing slide seat 501 to slide toward the second guide plate 3b, and a pushing roller 502 rotatably mounted on the pushing slide seat 501 to cooperate with the second guide plate 3b to laterally clamp the plate-shaped tray 100.

[0069] Both the first guide plate 3a and the second guide plate 3b are provided with a supporting horizontal surface 301 that supports the plate-shaped material tray 100 upwards. Each of the supporting horizontal surfaces 301 is provided with a blocking boss 302 on the side away from the other supporting horizontal surface 301 to prevent the plate-shaped material tray 100 from disengaging from the feeding guide mechanism 3. The pushing roller 502 is used to cooperate with the blocking boss 302 of the second guide plate 3b to push and position the plate-shaped material tray 100.

[0070] In this embodiment, both the first guide plate 3a and the second guide plate 3b are provided with elastic pressing components 6 for pressing the plate-shaped material tray 100 downward in conjunction with the corresponding supporting horizontal surface 301.

[0071] The elastic pressing assembly 6 includes a pressing sliding seat 601 that is slidably connected to the corresponding guide plate, a tension spring 602 that drives the pressing sliding seat 601 to slide downward, and a pressing roller 603 that is installed on the pressing sliding seat 601 and cooperates with the supporting horizontal surface 301 to press the plate-shaped material tray 100 downward.

[0072] During the feeding process, the tension spring 602 drives the downward pressing roller 603 to cooperate with the supporting horizontal surface 301 to press the plate-shaped material tray 100 downward, thereby preventing the plate-shaped material tray 100 from moving upward away from the feeding guide mechanism 3, thus achieving precise positioning of the plate-shaped material tray 100 in the vertical direction.

[0073] In this embodiment, both the first guide plate 3a and the second guide plate 3b are provided with a linkage adsorption mechanism 7 on the inner side of the end away from the layered silo 1 for adsorbing and positioning the plate-shaped material tray 100.

[0074] The linkage adsorption mechanism 7 includes a vertical sliding arm 701, a suction nozzle 702, and a linkage roller 703.

[0075] The vertical sliding arm 701 is slidably connected to the corresponding guide plate; wherein, the bottom of the vertical sliding arm 701 is provided with a guide slope 7011; the suction nozzle 702 is installed on the top surface of the vertical sliding arm 701; the linkage roller 703 is rotatably installed on the hook cylinder 401.

[0076] in,

[0077] When the linkage roller 703 disengages from the guide slope 7011, the top surface of the suction nozzle 702 is lower than the bottom surface of the plate-shaped material tray 100;

[0078] When the linkage roller 703 abuts against the guide inclined surface 7011 and is driven away from the layered hopper 1 by the hook linear drive mechanism 402, the top surface of the suction nozzle 702 moves upward to be close to the bottom surface of the plate-shaped material tray 100.

[0079] When the linkage roller 703 has not moved to the position of the guide slope 7011, the top surface of the suction nozzle 702 is lower than the bottom surface of the plate-shaped material tray 100, so the plate-shaped material tray 100 can be pulled forward smoothly.

[0080] As the linkage roller 703 gradually moves forward, under the action of the guide inclined surface 7011, the vertical sliding arm 701 gradually slides upward. Finally, when the plate-shaped material tray 100 is pulled to the designated position, the top surface of the suction nozzle 702 moves upward to be close to the bottom surface of the plate-shaped material tray 100, so as to adsorb and fix the plate-shaped material tray 100, prevent the plate-shaped material tray 100 from moving, and further improve the positioning reliability of the plate-shaped material tray 100.

[0081] Optionally, a hand crank screw assembly 8 is also provided for adjusting the distance between the two guide plates.

[0082] It should be noted that the linear drive mechanism mentioned in this utility model can be a cylinder, hydraulic cylinder, electric cylinder, or motor lead screw linear module, etc., and the rotary drive mechanism mentioned can be a brushed motor, brushless motor, or rotary cylinder, etc. This utility model does not limit the specific structural form of the linear drive mechanism and the rotary drive mechanism.

[0083] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
