Description

Technical Field

[0001] This utility model relates to the field of CNC machining technology, and in particular to an automatic material handling device. Background Technology

[0002] In the CNC (Computer Numerical Control) machining of 3C products, the substrate is a bar stock. The 3C product is machined at the top of the bar stock. After machining, there is a connection point between the workpiece and the bar stock, which needs to be manually broken to separate the workpiece and the bar stock, allowing for workpiece unloading and facilitating continuous bar stock machining. However, each workpiece requires manual unloading, resulting in low unloading efficiency. Furthermore, after machining all the bar stock on a worktable, the CNC machine tool must be stopped, and the machine door opened for manual unloading. Frequent opening and closing of the machine door leads to very low machine tool uptime and an excessively high human-machine ratio. Utility Model Content

[0044] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0045] Reference Figures 1 to 5 As shown, an automatic material handling device according to an embodiment of the present invention includes: a material platform 100 and a material handling rack 200.

[0046] The feed table 100 is used to fix the bar stock 120, which has been formed with workpiece 110 and connected to workpiece 110 by a connecting part. Specifically, the top surface of the feed table 100 is a processing plane. The part of the bar stock 120 that extends out of the processing plane will be processed by the machine tool into workpiece 110. There is a connection part with low connection strength between workpiece 110 and bar stock 120. The processing plane has multiple placement through holes for placing bar stock 120, so that the machine tool can process multiple workpieces 110 at a time, improving the production efficiency of the machine tool. When all the workpieces 110 on the top of all bar stock 120 have been removed, the feed table 100 pushes the bar stock 120 out and rises again, so that the distance of the bar stock 120 extending out of the processing plane is a preset distance, so that the machine tool can process it again until the bar stock 120 is consumed.

[0047] The material picker 200 is mounted on the material platform 100 and can move relative to the material platform 100. The material picker 200 includes a main frame 210, a bearing channel 220 located on the bottom surface of the main frame 210, and a bearing part 230 connected to the main frame 210. The bearing channel 220 defines a feeding channel 221 along a first direction. The bearing part 230 is located at the opening of the bearing channel 220 and defines a clearance channel 231 along the first direction. The clearance channel 231 connects the bearing channel 220 to the outside. The bearing part 230 is used to carry the workpiece 110.

[0048] In this embodiment, the through groove refers to a groove in which one pair of opposite sidewalls is machined into a through hole. In this embodiment, the supporting through groove 220 is rectangular, with one pair of opposite sidewalls being empty. The empty sidewalls and the space within the supporting through groove 220 form a feeding channel 221 along the first direction. In this embodiment, the feeding channel 221 can precisely accommodate the workpiece 110.

[0049] The support portion 230 is located at the slot opening to form a stop, preventing the workpiece 110 from exiting the support groove 220 along the slot opening. Instead, the workpiece moves relative to the support groove 220 in the first direction. Simultaneously, when the workpiece 110 is connected to the rod 120 via the connecting portion, the clearance channel 231 defined by the support portion 230 avoids the connecting portion. This allows the connecting portion to enter the clearance channel 231 when the workpiece 110 enters the support groove 220, and the connecting portion is stopped by the support portion 230. In this embodiment, the support portion 230 includes a first portion and a second portion, which are positioned opposite each other and spaced apart along the second direction, with the clearance channel 231 defined between them. Alternatively, one end of the support portion 230 may be connected to the main frame 210, and the other end may form the clearance channel 231 with a gap between it and the side wall of the support groove 220.

[0050] The material handling rack 200 includes a feeding action and a material handling action. The material handling rack 200 is configured such that: during the feeding action, the feeding channel 221 is aligned with the workpiece 110 along a first direction, the clearance channel 231 is aligned with the connecting portion along a first direction, and the material handling rack 200 moves along the first direction so that the workpiece 110 enters the bearing channel 220 along the first direction; during the material handling action, the workpiece 110 is located in the bearing channel 220, and the material handling rack 200 moves along a second direction perpendicular to the first direction to separate the workpiece 110 from the bar 120.

[0051] In this embodiment, the picking rack 200 is moved by a separate drive component. The drive component can be a robotic arm, a three-axis moving device, a two-axis moving device, or other moving devices that have at least two axes of movement. This structure and the connection method with the picking rack 200 are conventional technologies in the art and will not be described in detail here.

[0052] It is understandable that the pick-up rack 200 moves along the first direction to place the workpiece 110 within the carrying channel. Then, by moving along the second direction, the pick-up rack 200 causes the workpiece 110 to move relative to the bar 120 in the second direction. The connection point between the workpiece 110 and the bar 120 is subjected to shearing action and breaks, thus separating the workpiece 110 from the bar 120. This achieves automated picking without manual intervention, improves picking efficiency and machine tool uptime, and reduces the human-machine ratio.

[0053] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in some specific embodiments of this utility model, the automatic material handling device further includes a feeding component 300 and a blocking component 400.

[0054] A feeding component 300 is disposed on one side of the material platform 100, and the top of the feeding component 300 has a feeding port 310. In this embodiment, the feeding component 300 includes a feeding cavity communicating with the feeding port 310. The workpiece 110 is collected into the feeding cavity through the feeding port 310 for temporary storage, facilitating subsequent centralized retrieval. As another embodiment, the feeding component 300 is bucket-shaped and includes a large end and a small end. The large end has a feeding port 310, and the small end has a discharge port 320. The feeding component 300 serves as a guide to guide the workpiece 110 to a preset position and collect the workpiece 110 at the preset position, facilitating the transfer of the workpiece 110, reducing manual collection, and improving production efficiency.

[0055] The baffle 400 is located on one side of the unloading member 300 or inside the unloading member 300. The baffle 400 includes a baffle portion 410 that can pass through the feed channel 221 in a first direction. The pick-up rack 200 also includes a unloading action. The pick-up rack 200 is configured such that, during the unloading action, the pick-up rack 200 is located above the unloading port 310, and the feed channel 221 is aligned with the baffle portion 410 in the first direction, so that the workpiece 110 located in the bearing groove 220 is pushed out through the baffle portion 410 to the unloading port 310.

[0056] It is understandable that, through the stop part 410 of the stop member 400, the workpiece 110 is pushed out from the bearing channel 220 during the movement of the pick-up rack 200 in the first direction, thereby realizing the unloading of the workpiece 110 in the pick-up rack 200 and achieving automated unloading. Then, the unloading member 300 collects the workpiece 110 in a centralized manner, which facilitates the subsequent transfer of the workpiece 110 and achieves automated unloading of the workpiece 110. At the same time, it is convenient for the pick-up rack 200 to repeat the feeding and picking actions, and the pick-up rack 200 can automatically pick up the next batch of workpieces 110, thereby improving the working efficiency of the pick-up rack 200.

[0057] In this embodiment, the material platform 100 and the unloading component 300 are arranged sequentially along the first direction. The stop component 400 can be located between the material platform 100 and the unloading component 300, or the material platform 100, the unloading component 300, and the stop component 400 can be arranged sequentially, or the stop component 400 and the unloading component 300 can overlap along the first direction, that is, the stop component 400 is located inside the unloading component 300. Because the material platform 100 and the unloading component 300 are arranged along the first direction, the material picker 200 can move along the first direction to transport the workpiece 110 to the position of the unloading component 300. In addition, it should be noted that the first direction is based on the direction of the feed channel 221 in the bearing channel 220. When the bearing channel 220 rotates, the first direction also rotates, which can be understood as the entire coordinate system rotating. In another implementation, the material platform 100 and the unloading part 300 are arranged sequentially along the second direction. The picking rack 200 picks up the workpiece 110 along the first direction and rotates around the direction perpendicular to the processing plane. At this time, the direction of the feeding channel 221 rotates to be in the same direction as the original second direction, and the first direction is the same as the original second direction, so that the feeding channel 221 of the picking rack 200 is aligned with the stop part 400 along the first direction after rotation (the original second direction before rotation), and can move along the first direction toward the unloading part 300.

[0058] Wherein, the material stop 400 is disposed within the discharge port 310, and the distance between the material stop 400 and the side of the discharge port 310 facing the material platform 100 in the first direction is sufficient for the workpiece 110 to pass through and enter the discharge port 310, or the material stop 400 is disposed on the side of the discharge port 310 away from the material platform 100, when the material picker 200 moves toward the material stop 300 in the first direction, and the material stop 410 is inserted into the feeding channel 221 in the space above the discharge port 310, the workpiece 110 in the feeding channel 221 will be directly pushed out into the discharge port 310 by the material stop 410, completing the separation of the workpiece 110 from the material picker 200; after that, the material picker 200 can move toward the material platform 100 in the first direction to carry out a new round of material picking.

[0059] Alternatively, when the material picker 200 moves above the discharge port 310, the stop member 400 may align with the feed channel 221 in the first direction and move toward the feed channel 221 to push out the workpiece 110 within the carrying slot 220.

[0060] Reference Figure 2 , Figure 4 and Figure 5 As shown, in some specific embodiments of this utility model, the material stop 400 further includes a clearance portion 420 connected to the material stop portion 410; the material picker 200 is configured such that: during the material feeding action, the clearance channel 231 is aligned with the clearance portion 420 along the first direction; or the bearing portion 230 is aligned with the clearance portion 420 along the first direction, and the bearing portion 230 can be inserted into the clearance portion 420.

[0061] In this embodiment, when the clearance part 420 is a solid, the clearance part 420 is aligned with the clearance channel 231 along the first direction, and the blocking part 410 is aligned with the feeding channel 221 along the first direction, so that the blocking part 400 is located within the space formed by the feeding channel 221 and the clearance channel 231. During the process of the picking rack 200 passing through the blocking part 400 along the first direction, the blocking part 410 passes through the feeding channel 221 and pushes out the workpiece 110 in the feeding channel 221; the clearance part 420 passes through the clearance channel 231 to avoid the picking rack 200, so that the blocking part 400 will not affect the movement of the picking rack 200 along the first direction.

[0062] As another implementation, when the clearance part 420 is a virtual body, for example, when one end of the stop part 410 extends out along the first direction, a virtual clearance part 420 is formed around the end of the stop part 410. The stop member 400 will align only the stop part 410 with the feed channel 221 along the first direction, and can push out the workpiece 110 within the feed channel 221 during the movement of the pick-up rack 200 along the first direction. Specifically, the stop 400 includes a base plate, which is disposed on the side of the unloading member 300 away from the table 100 along a first direction. The stop part 410 is connected to the side of the base plate facing the table 100 and extends into the space above the unloading port 310 along the first direction. When the picking rack 200 moves toward the unloading member 300 along the first direction, and the stop part 410 is inserted into the feeding channel 221 in the space above the unloading port 310, the workpiece 110 in the feeding channel 221 will be directly pushed out into the unloading port 310 by the stop part 410, completing the separation of the workpiece 110 from the picking rack 200. Afterward, the picking rack 200 can move toward the table 100 along the first direction to perform a new round of picking. In this embodiment, the avoidance part 420 is a virtual body, and only the stop part 410 is inserted into the feeding channel 221. The stop 400 will not affect the normal movement of the picking rack 200.

[0063] In some specific embodiments of this utility model, the material stop 400 is disposed between the material feeder 300 and the material platform 100. The material stop 400 has a first position and a second position. The material stop 400 is configured to: in the first position, allow the material picker 200 and the bearing through groove 220 to move in a first direction so that the material picker 200 can move to align with the material feed port 310; in the second position, stop the workpiece 110 in the bearing through groove 220 so as to push out the workpiece 110.

[0064] It should be noted that the stop 400 is located between the unloading component 300 and the material platform 100. If the picking rack 200 moves directly toward the unloading component 300 along the first direction, the workpiece 110 inside the picking rack 200 will fall onto the material platform 100 instead of into the unloading port 310. In order to ensure that the workpiece 110 of the picking rack 200 can fall smoothly into the unloading port 310, the stop 400, through its own movement, avoids the movement of the picking rack 200 along the first direction during the process of the picking rack 200 moving from the material platform 100 to the unloading port 310; during the process of the picking rack 200 moving from the unloading port 310 to the material platform 100, it aligns with the feeding channel 221 along the first direction to push out the workpiece 110 inside the carrying slot 220.

[0065] In this embodiment, the movement process of the picking rack 200 and the avoidance process of the stop 400 are as follows: First, the picking rack 200 performs feeding and picking actions on the material platform 100; second, the picking rack 200 moves towards the unloading part 300 along the first direction, the stop 400 is in the first position, and the picking rack 200 moves directly to the unloading port 310 along the first direction; third, the stop 400 changes from the first position to the second position; finally, the picking rack 200 moves towards the material platform 100 along the first direction, and the picking rack 200 moves towards the stop 400 along the first direction on the unloading port 310, so that the workpiece 110 inside the picking rack 200 is pushed into the unloading port 310.

[0066] The stop component 400 can move along the second direction or along a third direction perpendicular to the first and second directions. The stop component 400 can switch between the first and second positions via a telescopic rod or a lead screw and slider structure.

[0067] Reference Figure 5 As shown, in some other specific embodiments of this utility model, the stop 400 is disposed between the unloading member 300 and the material table 100, and the pick-up rack 200 has a third position and a fourth position; the pick-up rack 200 is configured such that: in the third position, it avoids the stop 400 and moves to align with the unloading port 310; in the fourth position, it aligns with the stop 400 along the first direction to push out the workpiece 110.

[0068] It should be noted that the stop 400 is located between the unloading component 300 and the material table 100. If the picking rack 200 moves directly toward the unloading component 300 in the first direction, the workpiece 110 inside the picking rack 200 will fall onto the material table 100 instead of into the unloading port 310. In order for the workpiece 110 inside the picking rack 200 to fall smoothly into the unloading port 310, the picking rack 200 needs to first bypass the stop 400 and move onto the unloading port 310, and then move toward the stop 400, so that the workpiece 110 inside the picking rack 200 is pushed out into the unloading port 310 by the stop 400.

[0069] In this embodiment, the movement process of the material picker 200 is as follows: First, the material picker 200 performs feeding and picking actions on the material platform 100; second, the material picker 200 moves along the second direction to be offset from the stop member 400 along the first direction; third, the material picker 200 moves along the first direction to be aligned with the space above the discharge port 310 along the second direction; then, the material picker 200 moves along the second direction to the discharge port 310, while simultaneously aligning with the stop member 400 along the first direction; finally, the material picker 200 moves along the first direction toward the stop member 400 above the discharge port 310, causing the workpiece 110 inside the material picker 200 to be pushed into the discharge port 310.

[0070] Reference Figure 2 As shown, in some specific embodiments of this utility model, the automatic material handling device further includes a collecting component 500. The bottom of the feeding component 300 has a discharge port 320 connected to the feeding port 310, and the collecting component 500 is connected to the discharge port 320 to collect the workpiece 110. In this embodiment, the feeding component 300 serves to concentrate the workpiece 110, and the dedicated collecting component 500 collects the workpiece 110, facilitating subsequent processing of the workpiece 110.

[0071] Reference Figure 2 As shown, in some specific embodiments of this utility model, the collecting component 500 includes a first compartment and a second compartment. The collecting component 500 can move relative to the unloading component 300 to switch the first compartment or the second compartment to be connected to the discharge port 320. The number of workpieces 110 is distinguished by the first compartment and the second compartment, so that the number of workpieces 110 in each compartment is basically the same, thereby realizing the distinction of the number of workpieces 110.

[0072] Reference Figure 1 As shown, in some specific embodiments of this utility model, the second direction is parallel to the top surface of the feed platform 100. Alternatively, the second direction may be perpendicular to the top surface of the feed platform 100.

[0073] In some specific embodiments of this utility model, the automatic material handling device further includes a feeding component 300. The feeding component 300 is disposed on one side of the material platform 100, and the top of the feeding component 300 has a feeding port 310; the top of the main frame 210 can rotate around a second direction; the material handling frame 200 also includes a feeding action, and the material handling frame 200 is configured such that: during the feeding action, the material handling frame 200 is located above the feeding port 310, and the top of the material handling frame 200 rotates around a second direction so that the workpiece 110 in the carrying through groove 220 falls into the feeding port 310.

[0074] In this embodiment, the second direction is parallel to the top surface of the material platform 100. It is worth understanding that the material picker 200 can also rotate around the rotation axis in the same direction as the second direction via the main frame 210, so that the first direction of the feeding channel 221 is perpendicular to the top surface of the discharge port 310, and the workpiece 110 in the feeding channel 221 will also fall freely into the discharge port 310 under the action of gravity, thereby realizing the separation of the workpiece 110 from the material picker 200.

[0075] Reference Figure 3 and Figure 4 As shown, in some specific embodiments of this utility model, the material picker 200 includes a plurality of bearing channels 220 and a plurality of bearing parts 230 distributed sequentially along the second direction, with the bearing parts 230 corresponding one-to-one with the bearing channels 220.

[0076] In this embodiment, the second direction is parallel to the top surface of the material platform 100. There are multiple bearing portions 230 and bearing channels 220, distributed sequentially along the second direction. This allows the material picker 200 to directly separate the workpiece 110 from the bar stock 120 within each bearing channel 220 during the material pick-up action along the second direction. The material picker 200 can also unload multiple workpieces 110 at once, improving the material pick-up efficiency of the workpieces 110 and thus increasing overall production efficiency.

[0077] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
