These drawings and textual descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. Detailed implementation manners

[0055] Now, example embodiments will be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in various forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this application will be thorough and complete, and will fully convey the concept of the example embodiments to those skilled in the art. Like reference numerals in the figures denote like or similar parts, and thus their repeated description will be omitted.

[0056] In addition, the described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of the embodiments of the present application. However, those skilled in the art will realize that the technical solutions of the present application can be practiced without one or more of the specific details, or other methods, components, devices, steps, etc. can be adopted. In other cases, well-known methods, devices, implementations, or operations are not shown or described in detail to avoid obscuring aspects of the present application.

[0057] In a first aspect, an embodiment of the present application provides a workpiece conveying device for conveying columnar workpieces with an elongated shape. The cross-sectional shape of the workpiece can be arbitrary. In this embodiment, a workpiece with a hollow cylindrical shape is taken as an example to describe the workpiece conveying device in detail.

[0058] Refer to Figures 1 - 4, the workpiece conveying device 200 provided by the embodiment of the present application includes: a base 230, a conveying assembly 210, and a loading assembly 220. The conveying assembly 210 is disposed on the base 230 and has an inclined conveying surface 2100. The loading assembly 220 includes a lifting block 221, which is located on one side of the top end of the conveying surface and is movably connected to the base 230 to have a picking position higher than the top end of the conveying surface 2100 and a discharging position lower than the top end of the conveying surface 2100. The lifting block 221 is provided with an inclined guiding surface 2210, and the inclination direction of the guiding surface 2210 is the same as that of the conveying surface 2100. The projection position of the top end of the conveying surface 2100 on the guiding surface 2210 is located between the top end and the bottom end of the guiding surface 2210.

[0059] Among them, the workpiece conveying device 200 can be disposed between two processes to convey the workpiece 600 between the two processes. For example, the workpiece conveying device 200 is disposed between the loading process and the straightening process. The loading process is located on one side of the top end of the conveying surface 2100, and the straightening process is located on the low end side of the conveying surface 2100.

[0060] The guiding surface 2210 of the lifting block 221 can be arranged parallel to the conveying surface 2100. When the lifting block 221 is in the picking position, the guiding surface 2210 is higher than the conveying surface 2100. When the lifting block 221 is in the discharging position, the guiding surface 2210 is lower than the conveying surface 2100. During use, during the upward movement of the lifting block 221, the top part of the guiding surface 2210 can be used to lift the workpiece 600 from the previous process, and the lifted workpiece 600 will slide to the bottom part of the guiding surface 2210. Then, the lifting block 221 is lowered to the discharging position. During the downward movement of the lifting block 221, when the guiding surface 2210 is flush with the conveying surface 2100, the workpiece 600 will fall on the conveying surface, and at the same time, the lifting block 221 continues to descend and disengages from the workpiece 600, so that the workpiece 600 can be placed on the conveying surface and the workpiece 600 can slide downward along the conveying surface for conveying, realizing the automatic placement and conveying functions of the workpiece 600.

[0061] A driving component such as a cylinder, a hydraulic cylinder or an electric module can be set to be connected to the lifting block 221 to drive the lifting block 221 to perform a lifting action, so that the lifting block 221 moves between the picking position and the discharging position. The number of the lifting blocks 221 can be arbitrary. Exemplarily, the number of the lifting blocks 221 is two and they are arranged at intervals to jointly convey a longer workpiece 600 through the two lifting blocks 221.

[0062] In some embodiments, the loading assembly 220 further includes a first limiting portion 222, which is disposed at the bottom end of the guiding surface 2210.

[0063] Among them, the first limiting portion 222 can extend vertically upward relative to the lifting block 221. After the workpiece 600 is placed on the guiding surface 2210, when the workpiece 600 slides to the bottom end of the guiding surface 2210, it will abut against the first limiting portion 222, thereby preventing the workpiece 600 from falling off the lifting block 221. When the lifting block 221 is in the loading position, the height of the first limiting portion 222 is also lower than the conveying surface 2100 to avoid interfering with the movement of the workpiece 600.

[0064] In some embodiments, the lifting block 221 is further provided with a second limiting portion 223, and the second limiting portion 223 is located at the top end of the guiding surface 2210.

[0065] Among them, the second limiting portion 223 can also extend vertically upward relative to the lifting block 221. When the workpiece 600 moves upward and lifts the workpiece 600 in the previous process, the second limiting portion 223 can limit the reverse displacement of the workpiece 600 to ensure that the workpiece 600 accurately lands on the guiding surface 2210 of the lifting block 221.

[0066] In some embodiments, the conveying assembly 210 includes conveying rods 211. The number of the conveying rods 211 is at least two. The conveying rods 211 are inclined, and at least two conveying rods 211 are parallel to each other and arranged at intervals in the first direction. The conveying surface 2100 is the upper surface of the conveying rods 211.

[0067] Referring to Figure 2 , taking four conveying rods 211 as an example, the four conveying rods 211 are arranged at intervals along the axial direction of the workpiece 600 during conveying, and the distance between the two conveying rods 211 located on both sides is less than the length of the workpiece 600, so that the workpiece 600 can land on the four conveying rods 211 at the same time and slide downward along the upper surface of the conveying rods 211.

[0068] Among them, a support member can be provided at the position of the base 230 corresponding to the conveying rod 211, and the conveying rod 211 is fixed to the support member. The cross-sectional shape of the conveying rod 211 can be arbitrary. Exemplarily, the cross-sectional shape of the conveying rod 211 is circular, that is, the conveying surface 2100 is the part of the cylindrical surface of the conveying rod 211 facing upward, which can reduce the contact area with the workpiece 600 and make the sliding of the workpiece 600 smoother.

[0069] In the workpiece conveying device 200 according to the embodiment of the present application, the workpiece 600 is conveyed through the inclined conveying surface, and at the same time, the liftable lifting block 221 is used to grab and place the workpiece 600, so as to achieve the purpose of automatic feeding and conveying of the workpiece 600. The overall structure is simple, and the conveying speed of the workpiece 600 can be controlled by controlling the lifting frequency of the lifting block 221, which is easy to control and is suitable for conveying small-sized cylindrical workpieces 600, reducing the production cost.

[0070] In addition, referring to Figure 5 and Figure 6 , in actual use, multiple workpiece conveying devices 200 can be set up and arranged in sequence. Among them, when the lifting block 221 in the workpiece conveying device 200 located at the rear side is in the discharging position, it is simultaneously below the bottom end of the conveying rod 211 located at the front side, so as to be able to lift the workpiece 600 at the bottom end of the front-side conveying rod 211 during the process of the lifting block 221 moving upward to the discharging position, so as to be able to convey the workpiece 600 in sequence by using multiple workpiece conveying devices 200. A processing procedure can be set between every two adjacent workpiece conveying devices 200 to realize the automatic transfer and conveying function of the workpiece 600 in multiple procedures.

[0071] On the other hand, the embodiment of the present application further provides a workpiece straightening device, which includes at least one workpiece conveying device 200 provided in the first aspect embodiment, so as to convey the workpiece 600 through the workpiece conveying device 200 and straighten the workpiece 600 to ensure the straightness of the columnar workpiece 600.

[0072] Referring to Figure 7 and Figure 8 , in some embodiments, the workpiece straightening device further includes: a frame 100, a first cleaning device 300, a straightening device 400, and a second cleaning device 500. The frame 100 is provided with a feeding hopper 110 and a blanking box 120. The feeding hopper 110 has a storage cavity 1100 for placing the workpiece 600 and a blanking port communicating with the storage cavity 1100. The bottom surface of the storage cavity 1100 is inclined, and the blanking port is located at the lowest end of the bottom surface of the storage cavity 1100. The first cleaning device 300 is arranged on the frame 100 and is used for cleaning the workpiece 600 for the first time. The straightening device 400 is arranged on the frame 100 and is used for straightening the workpiece 600 after the first cleaning. The second cleaning device 500 is arranged on the frame 100 and is used for cleaning the workpiece 600 after straightening for the second time.

[0073] Among them, workpiece conveying devices 200 are arranged between the feeding hopper 110 and the first cleaning device 300, between the first cleaning device 300 and the straightening device 400, between the straightening device 400 and the second cleaning device 500, and between the second cleaning device 500 and the blanking box 120.

[0074] Specifically, a first workpiece conveying device 200a is provided between the upper hopper 110 and the first cleaning device 300, and is used to grab the workpiece 600 from the drop opening of the upper hopper 110, and then convey the workpiece 600 to the first cleaning device 300, so as to perform the first cleaning on the workpiece 600. A second workpiece conveying device 200b is provided between the first cleaning device 300 and the temporary storage device, and is used to convey the workpiece 600 after the first cleaning to the side of the straightening device 400, and use the straightening device 400 to straighten the workpiece 600. A third workpiece conveying device 200c is provided between the straightening device 400 and the second cleaning device 500, and is used to convey the straightened workpiece 600 to the second cleaning device 500, and use the second cleaning device 500 to perform the second cleaning on the workpiece 600. A fourth workpiece conveying device 200d is provided between the second cleaning device 500 and the blanking box 120 for conveying the workpiece 600 after the second cleaning into the blanking box 120 to store the workpiece 600 that has been straightened and cleaned.

[0075] Reference Figure 9 and Figure 10 In some embodiments, the upper hopper 110 includes: a cross brace 111, a side baffle 112, and a support rod 113. There are two side baffles 112, which are respectively connected to the two ends of the cross brace 111, and a material storage cavity 1100 is formed between the two side baffles 112. There is at least one support rod 113, which is obliquely arranged between the two side baffles 112, and the upper surface of the support rod 113 is the bottom surface of the material storage cavity 1100. The side baffles 112 and the support rod 113 are both connected to the frame 100, and a material drop opening is formed on one side of the two side baffles 112 toward the bottom end of the support rod 113.

[0076] The cross brace 111 is arranged horizontally, and two side baffles 112 are arranged at both ends of the cross brace 111 respectively. One end of the side baffle 112 away from the cross brace 111 is connected and fixed to the frame 100. There are multiple support rods 113 and they are arranged at intervals along the extension direction of the cross brace 111. The top end of the inclined support rod 113 is connected to the cross brace 111 and the bottom end is connected to the frame 100, so that the workpiece 600 can be stored in the storage cavity 1100 between the two side baffles 112, and the workpiece 600 will slide down along the support rod 113. A blocking structure is arranged at the bottom end of the frame 100 and the support rod 113 to prevent the workpiece 600 from falling directly from the blanking port.

[0077] In the first workpiece conveying device 200a, the top end of the first conveying rod 211a is located above the support rod 113. When the first lifting block 221a is at the loading position, the first lifting block 221a is also located below the support rod 113, and the top end portion of the guiding surface of the first lifting block 221a is directly opposite to a single workpiece 600 at the blanking port position. When the first lifting block 221a rises, it will lift the single workpiece 600 at the blanking port onto the guiding surface, and then use the guiding surface to slide the workpiece 600 to a position where it abuts against the limiting portion. When the first lifting block 221a descends, the workpiece 600 can be placed on the first conveying rod 211a, so that the workpiece 600 can slide along the first conveying rod 211a into the first cleaning device 300.

[0078] Combined with Figure 11 As shown, in some embodiments, the first cleaning device 300 includes a drive shaft 310 and a cleaning nozzle 320. The drive shaft 310 is rotatably connected to the frame 100. The number of drive shafts 310 is two and they are arranged at intervals. At least one drive wheel 311 is provided on the drive shaft 310, and a cleaning position 3110 for placing the workpiece 600 is formed between the two drive shafts 310. The cleaning nozzle 320 is located above the drive shaft 310 and is movably connected to the frame 100 to slide axially along the drive shaft 310 relative to the frame 100, for outputting a cleaning air flow to the workpiece 600 at the cleaning position 3110.

[0079] Exemplarily, drive wheels 311 are provided at both ends of each drive shaft 310. The cleaning position 3110 between the two drive wheels 311 should be located below the bottom end of the first conveying rod 211, so that the workpiece 600 can directly slide into the cleaning position 3110, that is, the workpiece 600 is supported on the two drive wheels 311, and the synchronous rotation of the two drive shafts 310 can drive the workpiece 600 to rotate around its own axis.

[0080] Among them, the two drive shafts 310 can be driven to rotate synchronously by setting a drive motor and a transmission belt, etc. No specific limitation is made in this embodiment.

[0081] The cleaning nozzle 320 is located above the cleaning position 3110. It can be connected to the cleaning nozzle 320 through a driving component such as a cylinder, a hydraulic cylinder or an electric module, and drive the cleaning nozzle 320 to reciprocally slide axially above the cleaning position 3110 along the workpiece 600, and blow out a cleaning air flow to the workpiece 600 to clean the debris generated when the workpiece 600 is stamped.

[0082] In the second workpiece conveying device 200b, the top end of the second conveying rod 211b is located above the cleaning position 3110 in the first cleaning assembly, and the second lifting block 221b is located below the cleaning position 3110, so that the workpiece 600 after the first cleaning can be placed in the second conveying rod 211b through the second lifting block 221b, and the workpiece 600 can be conveyed to the side of the straightening device 400 by the second conveying rod 211b.

[0083] The structure of the second cleaning device 500 may be consistent with that of the first cleaning device 300 , and will not be described in detail in this embodiment.

[0084] Reference Figure 12 and Figure 13 In some embodiments, the straightening device 400 includes a support seat 410 and a straightening block 420. The support seat 410 is provided with a positioning groove 411 for placing the workpiece 600. The straightening block 420 is movably connected to the frame 100 and is used to move toward the workpiece 600 placed in the positioning groove 411 to apply pressure to the workpiece 600 and straighten the workpiece 600.

[0085] Among them, two support seats 410 can be provided and spaced apart, and each support seat 410 is provided with a positioning groove 411. When placing the workpiece 600, the two ends of the workpiece 600 are respectively embedded in the support seats 410 on both sides to suspend the middle part of the workpiece 600. The straightening block 420 is directly opposite to the middle part of the two support seats 410, and can be connected to the straightening block 420 by providing a driving component such as a cylinder, a hydraulic cylinder or an electric module to drive the straightening block 420 to slide.

[0086] When placing the workpiece 600, the side of the workpiece 600 where the punching hole is formed is oriented away from the straightening block 420. When the straightening block 420 moves toward the workpiece 600, pressure away from the punching direction is applied to the workpiece 600 to drive the workpiece 600 to bend and deform in the opposite direction, and the workpiece 600 is restored to its straightness by relying on its own elasticity, thereby realizing the straightening function of the workpiece 600.

[0087] Optionally, the side of the straightening block 420 facing the workpiece 600 may be disposed in a groove that matches the shape of the workpiece 600 to avoid deformation of the shape of the workpiece 600 when the straightening block 420 applies pressure to the workpiece 600 .

[0088] In some embodiments, the straightening assembly further includes a limit block 430 disposed on the frame 100 and spaced apart from the straightening block 420 , and the portion of the workpiece 600 placed in the positioning groove 411 is between the limit block 430 and the straightening block 420 .

[0089] Among them, the limiting block 430 is arranged opposite to the straightening block 420, and the limiting block 430 can be made of materials such as rubber and polyurethane. When the straightening block 420 presses the workpiece 600 to bend, the pressed part of the workpiece 600 will be restricted by the limiting block 430 to prevent the workpiece 600 from being bent too much under pressure and causing bending deformation on the other side.

[0090] It should be noted that the workpiece 600 after being first cleaned by the first cleaning assembly can directly slide from the conveying rod 211b of the second workpiece conveying device 200b into the positioning groove 411, realizing the automatic conveying and positioning of the workpiece 600, but the accurate punching direction of the workpiece 600 towards the limiting block 430 side cannot be determined.

[0091] End holes will be formed at the ends of the workpiece 600 during the processing. The positioning pins 610 can be inserted into the through holes in advance, and the positioning surfaces 412 are arranged on the support seat 410. The placement position of the workpiece 600 is positioned by the contact between the positioning pins 610 and the positioning surfaces 412.

[0092] Therefore, in some embodiments, the frame 100 is further provided with a temporary storage rack 130. The temporary storage rack 130 is located between the first cleaning device 300 and the straightening device 400. A workpiece 600 conveying assembly 210 is arranged between the temporary storage rack 130 and the first cleaning device 300 for temporarily placing the workpiece 600 after the first cleaning.

[0093] Among them, the temporary storage rack 130 includes a temporary storage plate 131 and a rear baffle 132.
