Description

Technical Field

[0001] The present application relates to a parts picking device, belonging to the technical field of mechanical parts processing. Background Art

[0002] At present, in the mechanical processing industry, after the stamping process, the stamped parts need to be moved to the next process through a conveyor belt. During this process, the parts are often flipped. Since the front and back sides of the parts are different, the front side of the parts needs to be processed in the next process. However, after the stamping, the parts are flipped with the front side facing down, and the parts need to be flipped manually, which is time-consuming and labor-intensive, and has low production efficiency.

[0003] It should be noted that the above contents belong to the technical knowledge of the inventor and do not necessarily constitute prior art. Summary of the invention

[0004] In order to solve the above problems, the present application proposes a parts picking device, which moves the parts from the storage mechanism to the conveyor belt, preventing the parts from flipping over, saving the cost of manual flipping, saving time and effort, and improving the processing efficiency of the parts.

[0005] The present application provides a parts picking device, comprising:

[0006] A material storage structure, wherein a plurality of material storage openings are provided on the top of the material storage structure, and a top piece is provided in each of the material storage openings;

[0007] A material taking piece, wherein a material taking hole is provided on the material taking piece;

[0008] A fixed frame, wherein the fixed frame is provided with a guide structure for the material to perform linear motion;

[0009] The conveying structure includes a conveying belt, which is arranged in the fixed frame and adjacent to the material storage structure, and the conveying structure is used to convey the parts that fall off from the material taking part;

[0010] A driving structure, which is mounted on a fixed frame and connected to the material taking member, and is used to drive the material taking member to perform reciprocating linear motion along the guide structure above the material storage mechanism and the conveyor belt;

[0011] Among them, when the material picking piece moves to the top of the material storage structure, the material picking hole corresponds to the material storage port one by one, and the distance from the material picking piece to the material storage structure is less than the thickness of the component, and the distance from the material picking piece to the conveyor belt is greater than the thickness of the component.

[0012] Furthermore, the bottom of the material taking piece is gap-matched with the top of the material storage structure.

[0013] When the material picking piece moves to the top of the material storage structure, the material storage port pushes the components into the material picking hole through the internal pushing piece. The material picking piece drives the components to move horizontally to the top of the conveyor belt under the drive of the driving structure. The components fall off onto the conveyor belt under the action of gravity, and the conveyor belt moves the components to the next process.

[0014] Optionally, a limiting cover is provided on the top of the material taking hole, and a sleeve shaft for parts to be sleeved is provided in a material taking trough formed by the limiting cover and the material taking hole, and the sleeve shaft is fixed on the limiting cover.

[0015] The setting of the limit cover can prevent the parts from being ejected from the feeding hole. During the feeding process, when the feeding plate drives the parts to move horizontally from the stamping die to the conveyor belt, due to the height difference between the conveyor belt and the bottom of the feeding plate, the front end of the moving parts will fall on the conveyor belt first, and the feeding plate will continue to move forward, causing the rear end of the moving parts to flip 180 degrees in the feeding trough, facing down. Therefore, the sleeve shaft can limit the rear end of the moving parts from flipping 180 degrees in the feeding trough, further playing an anti-turnover role.

[0016] In one embodiment, the component is a columnar structure with an axial hole in the middle. The sleeve shaft has the same shape as the component axial hole and is clearance-matched to reduce the collision of the component with the inner wall of the material trough during the material picking and movement process. At the same time, the cylindrical structure can decompose the force applied to the component during transportation, thereby reducing the damage to the component caused by collision.

[0017] Optionally, the sleeve shaft does not protrude from the material extraction hole.

[0018] If the length of the sleeve protrudes too much from the bottom of the feeding plate, the parts may be restrained by the sleeve, and the feeding piece will continue to drive the parts to move on the conveyor belt, or affect the feeding plate from moving to the top of the storage structure; if the length of the sleeve is too short, it may not prevent the parts from tipping over in the feeding trough.

[0019] Furthermore, a weight-reducing shaft hole is provided in the sleeve shaft to reduce the overall weight of the material-retrieving component, reduce the load on the driving structure, and reduce energy consumption.

[0020] Optionally, the fixing frame includes two limiting plates arranged on both sides of the conveyor belt, and the guiding structure is arranged on the limiting plates.

[0021] Optionally, the material picking member is a material picking plate, the guiding structure is a guide rail arranged on the top of the limiting plate, the cross-section of the guide rail is two opposite L-shaped structures, and both sides of the material picking plate are provided with an inverted trapezoidal structure matching the L-shaped structure.

[0022] Optionally, a plurality of isolation strips are provided on the conveyor belt along the conveying direction, and the isolation strips divide the upper part of the conveyor belt into a plurality of conveying channels, and each conveying channel corresponds to at least one material taking hole;

[0023] The isolation strip does not contact the conveyor belt, and the isolation strip is fixed on the fixing frame.

[0024] It should be noted here that the setting of the isolation strip allows the parts ejected from the same material storage port to pass through the same conveying channel and enter the same next process, so as to facilitate marking, such as numbering, for later tracking. If a part with the same mark fails, the mark can be used to check whether the equipment of the production line producing the part has failed, so as to improve the efficiency of troubleshooting.

[0025] Optionally, the conveying channel corresponds to a material taking hole, and the material taking holes corresponding to adjacent conveying channels are staggeredly distributed on the material taking plate.

[0026] If the feeding holes or feeding slots are opened on the same straight line perpendicular to the movement direction of the feeding plate, the strength of the feeding plate at that straight line will inevitably be reduced. Long-term use will cause the feeding plate at that part to break, reducing the service life of the feeding plate. If the holes or feeding slots are opened in staggered distribution, the bearing capacity of the feeding plate can be properly balanced, thereby increasing the service life of the feeding plate.

[0027] Optionally, the driving structure is a rodless cylinder, a gantry is provided on the top of the fixed frame for the material picking piece to pass through, the rodless cylinder is installed at the bottom of the gantry, and a slider at the bottom of the rodless cylinder fixes the material picking piece.

[0028] Furthermore, reinforcing plates are provided on both sides of the rodless cylinder, and the reinforcing plates are fixed on the gantry. The provision of the reinforcing plates can further enhance the fixing strength of the rodless cylinder.

[0029] Optionally, a plurality of weight-reducing holes are provided on the material taking piece.

[0030] Optionally, the material storage structure is a bed mold, and the material storage port is a mold hole on a punch mold.

[0031] The beneficial effects of this application include but are not limited to:

[0032] 1. The parts picking device provided in the present application has a picking piece, when the picking piece moves to the top of the material storage structure, the material storage port pushes the parts into the picking hole, and the picking piece drives the parts to move horizontally to the top of the conveyor belt under the drive of the driving structure. The parts fall off onto the conveyor belt under the action of gravity, and the conveyor belt moves the parts to the next process. During the entire picking process, the parts only move horizontally without flipping, which saves the cost of manual flipping, saves time and effort, and improves the processing efficiency of parts.

[0033] 2. The component picking device provided in the present application has a limit cover in the picking hole to prevent the components from being ejected from the picking plate; the sleeve shaft is arranged to reduce the collision between the components and the inner wall of the picking hole during the picking process, and at the same time, the sleeve shaft with a cylindrical structure can decompose the force exerted on the components during transportation, thereby reducing the damage to the components caused by collision; the weight-reducing shaft hole opened in the sleeve shaft can reduce the weight of the limit member, thereby reducing the weight of the picking plate as a whole and reducing energy consumption.

[0054] In order to more clearly illustrate the overall concept of the present application, a detailed description is given below in an illustrative manner in conjunction with the accompanying drawings.

[0055] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0056] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0057] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0058] In this technical solution, if Figure 1-Figure 9 As shown, a component picking device is provided, which comprises: a material storage structure, a plurality of material storage ports are arranged on the top of the material storage structure; a picking piece, a picking hole 11 corresponding to the material storage port is opened on the picking piece; a fixed frame 2, a guide structure is arranged on the fixed frame 2, and the guide structure enables the picking piece to move linearly along it; a conveying structure comprises a conveyor belt 41, which is arranged inside the fixed frame, and the conveyor belt 41 is arranged adjacent to the material storage structure, and is used to convey the components 5 that fall off from the picking piece; the picking piece is fixedly connected to a driving structure The driving structure drives the material picking piece to make reciprocating linear motion along the guide structure above the material storage mechanism and the conveyor belt 41; when the material picking piece moves to the top of the material storage structure, the material picking hole 11 corresponds to the material storage port one by one, and the distance from the material picking piece to the material storage structure is not greater than the thickness of the component 5, so that the material picking hole 11 drives the component 5 to translate, and the distance from the material picking piece to the conveyor belt 41 is greater than the thickness of the component 5, so that the component 5 slides onto the conveyor belt 41 under the action of gravity, and is conveyed to the next processing procedure through the conveyor belt 41.

[0059] It should be noted that the material storage structure and how the material storage port ejects the components are not the technical points improved in this application and will not be described in detail here.

[0060] In one embodiment, reference Figure 4-Figure 6 A feeding hole 11 is provided on the feeding piece to prevent the component 5 from being ejected from the feeding hole 11. A limit cover 12 is installed on the upper part of the feeding hole 11. A mounting plate 121 is provided on the limit cover 12. The limit cover 12 is fixed to the feeding piece through the mounting plate 121. In another embodiment, the limit cover 12 is integrally arranged with the feeding hole 11. Furthermore, the limiting cover 12 and the feeding hole 11 form a feeding trough, and a sleeve shaft 13 for the component 5 to be sleeved is provided in the feeding trough, and the sleeve shaft 13 and the limiting cover 12 are integrally formed. During the feeding process, when the feeding member drives the component 5 to move horizontally from the stamping die 6 to the conveyor belt 41, due to a certain height difference between the conveyor belt 41 and the bottom of the feeding member, the front end of the moving component 5 will first fall onto the conveyor belt 41, and the feeding member will continue to move forward, causing the rear end of the moving component 5 to flip 180 degrees in the feeding trough, facing downward. Therefore, the sleeve shaft 13 can limit the rear end of the moving component from flipping 180 degrees in the feeding trough, thereby further playing an anti-turnover role.

[0061] Specifically, the parts punched out by the punch die 6 are as follows: Figure 6As shown, it includes a first columnar structure 51 and a second columnar structure 52, the first columnar structure 51 and the second columnar structure 52 are coaxially arranged, and the component 5 is provided with a component shaft hole 53. Correspondingly, the sleeve shaft 13 is also a cylindrical structure, so that the component shaft hole 53 is sleeved on the sleeve shaft 13 of the cylindrical structure. Further, the sleeve shaft 13, the limit cover 12 and the feeding hole 11 are coaxially arranged, and the component shaft hole 53 just contacts the outer wall of the sleeve shaft 13, which does not affect the component 5 from sliding onto the conveyor belt 4. Such an arrangement can reduce the collision between the component 5 and the inner wall of the feeding hole 11 during the feeding process. At the same time, the sleeve shaft 13 of the cylindrical structure can decompose the force applied to the component 5 during transportation, thereby reducing the damage to the component 5 caused by the collision.

[0062] The limit cover 12 is not limited to Figure 5 The structure shown may also be in other forms, as long as it can prevent the component 5 from being ejected and does not affect the reciprocating motion of the material taking plate 1.

[0063] Preferably, a weight-reducing shaft hole 131 is provided in the sleeve shaft 13, and a plurality of weight-reducing holes 14 are provided on the material picking member. Since the material picking member is made of a metal plate such as steel or aluminum, and is relatively heavy, the weight-reducing shaft hole 131 and the weight-reducing holes 14 can reduce the weight of the material picking member as a whole, that is, save the weight of the driving structure, save energy consumption, and save raw materials.

[0064] In a preferred embodiment, the sleeve shaft 13 does not protrude from the feeding hole 11. If the length of the sleeve shaft 13 protrudes from the bottom of the feeding plate 1, the component 5 may be restrained by the sleeve shaft 13, and the feeding plate 1 continues to drive the component 5 to move on the conveyor belt 41, or the feeding plate 1 is affected from moving to the top of the material storage structure; if the length of the sleeve shaft 13 is too short, it may not play a role in preventing the component 5 from turning over in the feeding trough.

[0065] In one embodiment, reference Figure 1-Figure 3 , Figure 7 The fixed frame 2 includes a limit plate 21 fixed on both sides of the conveyor belt 41, and the guide structure is two parallel guide rails 22 arranged on the top of the limit plate 21. The cross section of the guide rail 22 is two opposite L-shaped structures. The material picking piece is a material picking plate 1. The side of the material picking plate 1 is an inverted trapezoidal structure used in conjunction with the L-shaped structure, so that the material picking plate 1 is placed between the two parallel guide rails 22. The guide structure is not limited to the above-mentioned guide rail form, and can also be other forms of guide structures, as long as the material picking plate 1 can be linearly moved between the stamping die 6 and the conveyor belt 41. In addition, the fixed frame 2 also includes a reinforcing rib or a reinforcing plate connecting the two limit plates 21 to enhance the fixing strength of the fixed frame 2.

[0066] In one embodiment, reference Figure 1 , Figure 7 and Fig. 9The conveying structure 4 is a conveyor, which includes a conveyor belt 41 and a conveying motor 42. The conveyor belt 42 is provided with a plurality of parallel isolation strips 23. The isolation strips 23 divide the upper part of the conveyor belt into a plurality of parallel conveying channels along the transmission direction, so that the parts 5 in the same material taking hole 11 can be placed in the same conveying channel. The isolation strips 23 are fixed on the reinforcing ribs of the fixed frame 2, and the isolation strips 23 and the conveyor belt 41 are gap-matched.

[0067] It should be noted here that the setting of the isolation strip 23 allows the parts 5 produced by the same punch die hole 61 to pass through the same conveying channel and enter the same next process, so as to facilitate marking, such as numbering, for later tracking. If a part with the same mark fails, the mark can be used to check whether the equipment of the production line producing the part has failed, so as to improve the efficiency of troubleshooting.

[0068] refer to Fig.10 The punch die holes 61 on the punch die 6 correspond one-to-one to the material taking holes 11 on the material taking plate 1 . In order to improve the production efficiency of the parts 5 , each conveying channel can correspond to a plurality of material taking holes 11 .

[0069] In a preferred embodiment, in order to balance the bearing capacity of the feeding plate 1 and increase the service life of the feeding plate 1, the feeding holes 11 corresponding to adjacent conveying channels are staggered. If the feeding holes 11 are opened on the same straight line perpendicular to the movement direction of the feeding plate 1, the strength of the part of the feeding plate where the straight line is located will inevitably be reduced. Long-term use will cause this part of the feeding plate to break, reducing the service life of the feeding plate. Therefore, in this embodiment, the feeding holes or feeding troughs corresponding to adjacent conveying channels are staggered.

[0070] In one embodiment, reference Figure 1 , Figure 2 and Figure 8 The driving structure is a rodless cylinder 3, a gantry 24 is installed on the top of the fixed frame 2, and the bottoms of the two sides of the gantry 24 are respectively fixed to the outside of the two limit plates 21, and the rodless cylinder 3 is installed at the bottom of the gantry 24. The slider 31 at the bottom of the rodless cylinder 3 fixes the material-retrieving plate 1, and the material-retrieving plate 1 performs reciprocating linear motion under the gantry 24 under the drive of the rodless cylinder 3. Further, reinforcing plates 25 are provided on both sides of the rodless cylinder 3, and the reinforcing plates 25 are fixed on the gantry. The setting of the reinforcing plates 25 can further strengthen the fixing strength of the rodless cylinder 3.

[0071] The driving structure may also be other forms of air cylinders or oil cylinders, as long as they can drive the feeding plate 1 to move horizontally.

[0072] Each embodiment in this specification is described in a progressive manner, and the same or similar parts between the embodiments can be referred to each other, and each embodiment focuses on the differences from other embodiments. In particular, for the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiment.

[0073] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
