DETAILED DESCRIPTION

[0038] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention unless otherwise specifically stated.

[0039] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0040] Techniques and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the techniques and equipment should be considered part of the specification.

[0041] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0042] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0043] According to one embodiment of the present disclosure, a blanking feeder is provided, such as Figure 1-Figure 3 As shown, the punching and feeding machine comprises: a punching device 1 and a material shifting device 2.

[0044] The punching device 1 is provided with a first material trough and a punching knife 11 , and the punching knife 11 is used for punching the material strip 5 in the first material trough.

[0045] The material dispensing device 2 is provided with a second material trough, a material strip correction device 21 and a material dispensing device 22. The material dispensing device 22 is used to drive the material strip 5 in the second material trough to move. The feed end of the second material trough is arranged opposite to the discharge end of the first material trough. The material strip 5 enters the punching device through the feed end of the first material trough, and after being cut by the punching knife 11 and being moved by the material dispensing device 2, it is discharged from the material dispensing device through the discharge end of the second material trough. The material strip correction device 21 is used to correct the position of the material strip 5 relative to the punching knife 11.

[0046] When using the punching feeder for processing, the feed end of the first trough of the material strip 5 needs to be extended into the first trough, and then extended out of the first trough through the discharge end of the first trough. The material strip 5 extending out of the first trough enters the second trough through the feed end of the second trough, and the material tapper 22 taps the material strip 5 in the second trough to move the material strip 5 and discharge it from the second trough through the discharge end of the second trough. The material strip correction device 21 can correct the position of the material strip 5 after it enters the second trough from the first trough to ensure that the position of the material strip 5 in the first trough meets the position requirements when the punching knife 11 is cutting. In this way, the position of the material strip 5 to be cut can be more accurate relative to the cutting position of the punching knife 11. For example, the material tapper 22 can be a gear, and the teeth of the gear cooperate with the material strip 5, and rotating the gear can drive the material strip 5 to move.

[0047] In this embodiment, the material strip 5 in the first material trough is driven to move by the material tapper 22 on the material tapping device 2, and the material strip correction device 21 on the material tapping device 2 can correct the material strip 5 extending from the first material trough to the second material trough, so that the material strip 5 can correspond to the position of the punching knife 11 more accurately, thereby enabling the cutting process of the punching knife 11 to have higher accuracy, which can meet the accuracy of the workpiece obtained after cutting.

[0048] For example, a feeding trough 6 is provided at one side of the feeding end of the first trough, and the material strip 5 enters the first trough through the feeding trough 6. The material strip correction device 21 and the position of the coil of the material strip 5 are positioned on both sides of the punching device 1, and the material strip 5 passing through the first trough is corrected by the material strip correction device 21, so that the material strip 5 can maintain an accurate moving route, and the position of the material strip 5 to be punched can be kept accurately matched with the position of the punching knife 11, so that the cutting has a higher cutting accuracy, and the accuracy of the workpiece obtained after cutting is reduced.

[0049] The blanking feeder in this embodiment cuts the material strip 5, which does not require manual material feeding and swinging, and the material strip 5 allows the blanking device 1 to continuously feed materials, saving labor and improving cutting efficiency. The blanking feeder has a simpler structure, reduces the size of the equipment, and saves space. There are fewer processes for forming workpieces, reducing the steps of the blanking process.

[0050] For example, the material belt correction device 21 includes a positioning detection device and a correction device. The positioning detection device is used to detect whether the material belt 5 is accurately positioned on the preset conveying route. When the material belt deviates from the preset conveying route, the correction device is used to adjust the material belt 5 to the preset conveying route to ensure that the material belt 5 remains on the accurate conveying route, thereby ensuring that the punching knife 11 can maintain a high-precision punching process with the material belt 5, thereby improving the punching accuracy.

[0051] The positioning detection device may be, for example, a positioning sensor. The deflection correction device may be a deflection correction plate and / or a deflection correction roller. For example, the deflection correction plate is disposed on the side or bottom of the material belt 5, and the material belt 5 is corrected by the deflection correction plate. For example, the deflection correction roller forms an angle with respect to the direction of the material belt 5, and the deflection correction roller is disposed at the bottom of the material belt 5, and the material belt 5 is corrected by rolling the deflection correction roller.

[0052] For example, the material belt correction device 21 may be an automatic return device disposed on both sides of the material belt 5. When the automatic return device is squeezed by the material belt 5 and deviates, it can automatically return to its original position, thereby driving the material belt 5 to return to its original position. For example, the automatic return device includes a sensing device for sensing the deviation and a return device for automatic return. The sensing device is used to sense the deviation of the material belt, and the return device is located on both sides of the material belt 5 and is used to drive the material belt 5 to return to its original position.

[0053] In one implementation, the punching and feeding machine further includes a transfer device disposed downstream of the material diverting device 2, and the transfer device includes:

[0054] The material taking and placing device comprises a first electric slide rail 31 and a suction nozzle device 32 , and the suction nozzle device 32 is slidably connected to the first electric slide rail 31 .

[0055] The transfer device includes a second electric slide rail 41 and a transfer platform 42, and the transfer platform 42 is slidably connected to the second electric slide rail 41. The suction nozzle device 32 is used to suck the workpiece formed after the punching device 1 is punched and place it on the transfer platform 42. After the suction nozzle device 32 sucks the workpiece above the punching device 1, it moves to the transfer platform 42 through the first electric slide rail 31 and places the workpiece on the transfer platform 42 through the suction nozzle device 32. The transfer platform 42 can move on the second electric slide rail 41, and can carry the workpiece to the position where the robot grasps the workpiece for the injection molding process, and the robot grasps the workpiece for injection molding.

[0056] In one embodiment, Figure 1-Figure 5 As shown, the punching device 1 includes a punching device body 12, an upper die plate 13, a lower die plate 14 and a lower die plate driving device.

[0057] The upper template 13 and the lower template driving device are arranged on the punching device body 12, and the lower template 14 is arranged on the lower template driving device. The upper template 13 is located above the lower template 14, and the lower template driving device can drive the lower template 14 to move toward or away from the upper template 13.

[0058] The first material trough is arranged on the upper template 13 , and the first material trough has a punching opening. When the material strip 5 is placed in the first material trough, the punching opening is located below the material strip 5 .

[0059] The punching blade 11 includes an upper punching blade and a lower punching blade. The upper punching blade is arranged on the upper template 13 and is located above the first material trough. The lower punching blade is arranged on the lower template 14 and is located below the first material trough. The lower punching blade can enter the first material trough through the punching opening. After the material strip 5 enters the first material trough, the material strip 5 is located between the upper punching blade and the lower punching blade.

[0060] In this implementation, the lower template 14 moves toward or away from the upper template 13 , which can drive the lower punch knife to approach or away from the upper punch knife, so as to realize the cutting function of the upper punch knife and the lower punch knife on the material strip 5 .

[0061] After the material strip 5 is corrected by the material strip correction device 21, the tape cutting portion on the material strip 5 can be accurately located in the cutting area of ​​the upper punch and the lower punch. For example, after the end of the coil is pulled out, it enters from the feed end of the first material trough through the feed trough 6, and passes through the discharge end of the first material trough and the feed end of the second material trough in turn to enter the second material trough. The position of the material strip 5 when entering through one side of the feed trough 6 remains stable, and the material strip correction device 21 corrects the material strip 5 on the other side of the punching device 1. This ensures that both ends of the material strip 5 entering and leaving the punching device 1 are accurately positioned, so that the tape cutting position of the material strip 5 is accurately positioned with the upper punch and the lower punch, thereby improving the cutting accuracy.

[0062] In one embodiment, Figure 5 As shown, the lower template driving device includes an upper cylinder 151 and a floating joint 152, the floating joint 152 is connected to the lower template 14, the upper cylinder 151 is connected to the punching device body 12, and the output end of the upper cylinder 151 is connected to the floating joint 152.

[0063] In this embodiment, the floating joint 152 is driven to move up and down by the upper cylinder 151 on the punching device body 12 , so that the lower mold plate 14 can approach or move away from the upper mold plate 13 .

[0064] By controlling the movement of the upper cylinder 151 , the frequency at which the lower template 14 drives the lower punch to cooperate with the upper punch can be controlled, thereby coordinating the movement of the material strip 5 so that the blanking device 1 can cut the material strip 5 continuously and accurately.

[0065] For example, a support plate 141 is disposed on the lower template 14 , and the lower punch is disposed on the support plate 141 , and the support plate 141 moves along with the lower template 14 .

[0066] In one embodiment, two first material troughs are arranged on the upper template 13, and the two first material troughs are arranged in parallel. The two first material troughs can feed two material strips 5 into the punching device at the same time.

[0067] The upper punch includes a first upper punch 111, a second upper punch 112 and a third upper punch 113 located between the first upper punch 111 and the second upper punch 112. The third upper punch 113 is located between the two first material troughs. The first upper punch 111 and the second upper punch 112 are located on both sides of the two first material troughs.

[0068] The lower punch includes a first lower punch and a second lower punch;

[0069] The first lower punch is located below one of the first material slots, and the first lower punch, the first upper punch 111 and the third upper punch 113 are used to punch out the material strip in the first material slot;

[0070] The second lower punch is located below another first material trough, and the second lower punch, the second upper punch 112 and the third upper punch 113 are used to punch out the material strip in the first material trough.

[0071] The first upper punch 111, the second upper punch 112 and the third upper punch 113 are located above the two first material troughs, and the first lower punch and the second lower punch are located below the two first material troughs, so that the material strips 5 in the two first material troughs can be cut synchronously.

[0072] In this embodiment, two material strips 5 can be cut synchronously, which effectively improves the cutting efficiency and the processing efficiency of the workpiece.

[0073] For example, the suction nozzle device 32 simultaneously sucks the workpieces cut from the two material strips 5 and transfers them to the transfer platform 42 .

[0074] In one embodiment, the lower punch includes a plurality of lower punch portions, and the plurality of lower punch portions are distributed along the tape cutting area on the material tape 5 , and the upper punch includes a plurality of upper punch portions corresponding to the plurality of lower punch portions.

[0075] In this embodiment, the plurality of lower punching parts cooperate with the plurality of upper punching parts, and the lower punching parts move toward the upper punching parts to synchronously cut out a plurality of workpieces on the material strip 5. In this way, a plurality of workpieces can be processed each time the cutting is performed, thereby improving the processing efficiency.

[0076] For example, the two first material troughs are provided with synchronously running material belts 5 , and each material belt 5 can be synchronously cut into multiple workpieces. The suction nozzle device 32 sucks the synchronously cut multiple workpieces and transports them to the transfer platform 42 .

[0077] In one embodiment, the upper template 13 is provided with a guide column, and the lower template 14 is provided with a guide hole, and the guide column cooperates with the guide hole.

[0078] In this embodiment, the guide post and the guide hole cooperate so that the lower template 14 can move along the guide post during movement, thereby ensuring that the lower template 14 maintains sufficient accuracy when approaching or moving away from the upper template 13, thereby improving the cutting accuracy.

[0079] In one embodiment, a waste strip cutter 23 is provided at the discharge end of the second trough.

[0080] The waste tape left after the cut material tape 5 is sent out through the discharge end of the second material trough, and the discharge end of the second material trough is provided with a waste tape cutter 23 to cut the waste tape. By setting the cutting rate of the waste tape cutter 23 and matching the moving speed of the material tape 5, the waste tape can be cut into a predetermined size for easy collection.

[0081] In one embodiment, Figure 1-Figure 3 As shown, the nozzle device 32 includes a nozzle device body 321, a nozzle carrier plate 322 and a nozzle 323. The nozzle device body 321 is slidably connected to the first electric slide rail 31, the nozzle carrier plate 322 is slidably connected to the nozzle device body 321, the nozzle carrier plate 322 can slide up and down along the nozzle device body 321, and the nozzle 323 is connected to the nozzle carrier plate 322.

[0082] In this embodiment, the nozzle device body 321 is slidably connected to the first electric slide rail 31 so that the nozzle device 32 can move along the first electric slide rail 31 .

[0083] The nozzle carrier plate 322 can slide up and down along the nozzle device body 321, so that the nozzle 323 can approach or move away from the punching device 1, so that it can approach the punching device 1 to suck the workpiece and move away from the punching device 1, and the nozzle device body 321 slides on the first electric slide rail 31 to drive the nozzle 323 on the nozzle carrier plate 322 to move toward the transfer platform 42. After the nozzle device 32 moves to the top of the transfer platform 42, the nozzle carrier plate 322 is moved downward to make the nozzle 323 approach the transfer platform 42 and place the workpiece on the nozzle 323 on the transfer platform 42.

[0084] For example, a vacuum pressure switch is provided on the suction nozzle device body 321, and the vacuum pressure switch is used to detect the pressure inside the suction nozzle to detect whether the suction nozzle sucks the workpiece.

[0085] In one embodiment, Figure 1-Figure 3 As shown, a distance adjusting device 324 and a plurality of the suction nozzles 323 are provided on the suction nozzle carrier plate 322 , and the distance adjusting device 324 is used to adjust the distance between the plurality of the suction nozzles 323 .

[0086] In this embodiment, the distance adjustment device 324 can adjust the distance between the multiple suction nozzles 323 used to suck the workpieces, so that after the multiple suction nozzles 323 suck the workpieces, the preset distance between the workpieces can be maintained to facilitate subsequent processes.

[0087] For example, the spacing between the multiple suction nozzles 323 is set to the spacing between the workpieces during injection molding, and the workpieces are placed on the transfer platform 42 at the spacing required for injection molding through the multiple suction nozzles 323, and the transfer platform 42 is moved to the position where the robot arm picks up the workpieces in the injection molding process through the second electric slide rail 41. In this way, the robot arm can directly grab multiple workpieces with spacing that meets the requirements without having to re-place them, saving processes and improving processing efficiency.

[0088] For example, in an embodiment with two first material troughs, each material strip 5 is cut into multiple workpieces synchronously, and multiple suction nozzles 323 suck the workpieces and adjust the distance between them through the distance adjustment device 324 before placing them on the transfer platform 42. The transfer platform 42 is provided with multiple transfer stations corresponding to the multiple workpieces, and each workpiece suction nozzle 323 is placed on the corresponding transfer station 421.

[0089] In one embodiment, the punching knife 11 includes a plurality of punching parts, and the plurality of punching parts correspond to the plurality of suction nozzles 323 . The plurality of punching parts can punch synchronously to form a plurality of workpieces.

[0090] The nozzle carrier plate 322 is provided with a positioning column 3221 , and the punching device 1 is provided with a positioning hole 131 .

[0091] In this embodiment, multiple blanking parts can cut out multiple workpieces at the same time, and multiple suction nozzles 323 suck the workpieces and transfer them to the transfer platform 42. Before being transferred to the transfer platform 42, the distance between the suction nozzles 323 is adjusted by the distance adjustment device 324, so that the distance between the workpieces placed on the transfer platform 42 meets the process requirements of subsequent injection molding.

[0092] The positioning column 3221 cooperates with the positioning hole 131 to ensure that the suction nozzle 323 is accurately positioned at the tape cutting position corresponding to the material tape 5 when the suction nozzle carrier plate 322 moves toward the punching device 1, so as to accurately suck the workpiece.

[0093] For example, the positioning hole 131 is provided on the upper template 13, the upper template 13 is located on the upper side of the punching device 1, and the first material slot is located on the upper template 13. The positioning hole 131 is provided on the upper template 13 so that it is easier to cooperate with the positioning column 3221.

[0094] For example, when the nozzle carrier plate 322 moves toward the blanking device 1, the positioning column 3221 extends into the positioning hole 131. The nozzle carrier plate 322 continues to move downward, and the positioning column 3221 moves along the positioning hole 131, ensuring that when the nozzle carrier plate 322 moves downward, the nozzle 323 is aligned with the position of the workpiece, ensuring the accuracy of the nozzle 323 when it reaches the position to suck the workpiece.

[0095] The above embodiments focus on the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. Considering the simplicity of the text, they will not be repeated here.
