[0002] like Figure 1 The diagram shows the structure of a metal sheet 10, which has comb-like grooves 11. This metal sheet 10 is a semi-finished product and requires subsequent processing, such as laser marking. When the supplier delivers the materials, several metal sheets 10 are stacked together sequentially (e.g., ...). Figure 2 As shown, several stacked hardware panels 10 need to be separated one by one and transported to the target workstation. The aforementioned hardware panel 10 has a bent portion 12 in its middle. Due to the presence of this bent portion 12, gaps will appear between two adjacent hardware panels 10 after several hardware panels 10 are stacked together.

[0003] Based on the structural characteristics of the aforementioned hardware plate 10, the technical problem that needs to be solved is how to design and develop an integrated cutting and conveying device to cut out several sequentially stacked hardware plates 10 one by one and convey them to the target workstation in one step.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0045] like Figure 3As shown, the present invention discloses an integrated cutting and conveying device 20 for hardware sheet metal parts, including: a storage mechanism 100, a pushing mechanism 200, and a cutting mechanism 300.

[0046] like Figure 3 and Figure 4 As shown, the storage mechanism 100 includes a storage bin 110 and a linear vibrator 120 disposed within the storage bin 110. Further, the linear vibrator 120 has a locking limiting plate 121 (as shown). Figure 3 As shown, several stacked hardware plates 10 are placed in the storage bin 110. Some of the comb grooves 11 of the hardware plates 10 are engaged with the snap-fit ​​limiting plate 121. The snap-fit ​​limiting plate 121 plays a limiting role for the hardware plates 10, so that the several stacked hardware plates 10 can stably reach the outlet of the storage bin 110 under the action of the vibrator 120.

[0047] like Figure 5 As shown, the pushing mechanism 200 includes a support platform 210, a pushing rod 220, and a pushing drive unit 230. A material discharge groove 211 is provided on the support platform 210. The pushing drive unit 230 is drivenly connected to the pushing rod 220, causing one end of the pushing rod 220 to slide reciprocally along the material discharge groove 211. In this embodiment, the pushing drive unit 230 is a cylinder.

[0048] like Figure 5 As shown, the cutting mechanism 300 includes: a fixed base 310, a cutting shaft 320, and a cutting drive unit 330. (As shown...) Figure 6 As shown, the fixed base 310 includes: a sealing plate 311 disposed at the outlet of the storage bin 110, and a buffer ramp 312 connecting the outlet of the storage bin 110 and the discharge chute 211; the cutting shaft 320 is located above the buffer ramp 312, and the cutting drive unit 330 is used to drive the cutting shaft 320 to rotate. In this embodiment, the cutting drive unit 330 is a servo motor.

[0049] like Figure 6 As shown, the sealing plate 311 is provided with a number of clearance grooves 313 spaced apart along its extension line.

[0050] like Figure 5 and Figure 7 As shown, the shearing shaft 320 is provided with a plurality of first elastic rods 321 and a plurality of second elastic rods 322. The plurality of first elastic rods 321 are arranged at intervals along the axial direction of the shearing shaft, and the plurality of second elastic rods 322 are arranged at intervals along the axial direction of the shearing shaft. Figure 7As shown, in this embodiment, the tail of the first elastic rod 321 forms a first barb 3211, and the tail of the second elastic rod 322 forms a second barb 3221. By setting the first barb 3211 and the second elastic rod 322, the hardware plate 10 at the outlet of the storage bin 110 can be hooked out more effectively.

[0051] Preferably, both the first elastic rod 321 and the second elastic rod 322 are made of plastic. The plastic first elastic rod 321 and the second elastic rod 322 not only have elasticity but also are less likely to scratch the surface of the metal plate 10. In other embodiments, both the first elastic rod 321 and the second elastic rod 322 can be made of metal.

[0052] The working principle of the above-mentioned integrated cutting and conveying device 20 for metal sheet parts will be explained below:

[0053] like Figure 3 As shown, several stacked hardware plates 10 are placed in the storage bin 110, and some comb grooves 11 of the hardware plates 10 are engaged on the snap-fit ​​limiting plate 121.

[0054] Based on the linear vibration of the linear vibrator 120, several stacked metal plates 10 move towards the outlet of the storage bin 110; it should be noted that, in order to better see the structure in the attached drawings, Figure 3 and Figure 4 In the process, several hardware plates 10 are spaced apart, but in reality, the hardware plates 10 are tightly attached to each other.

[0055] The hardware plate 10 closest to the outlet of the storage bin 110 is defined as the foremost hardware plate. When the foremost hardware plate is removed, the adjacent hardware plate 10 is pushed to the outlet of the storage bin 110 and becomes the new foremost hardware plate.

[0056] like Figure 8 As shown, the cutting drive unit 330 drives the cutting shaft 320 to rotate forward, so that one end of several first elastic rods 321 passes through several clearance grooves 313 and enters the outlet of the storage bin 110, and one end of the first elastic rod 321 hooks the comb groove 11 of the foremost hardware plate 10.

[0057] like Figure 9 As shown, the cutting drive unit 330 drives the cutting shaft 320 to reverse, and one end of the first elastic rod 321 cuts the foremost metal plate 10 out from the outlet of the storage bin 110; after the foremost metal plate 10 is completely cut out from the outlet of the storage bin 110, the metal plate 10 will slide along the first elastic rod 321 until it contacts the cutting shaft 320 (e.g., Figure 9As shown), the cutting-off shaft 320 forms a blockage on the hardware plate 10;

[0058] like Figure 10 and Figure 11 As shown, immediately afterwards, the cutting drive unit 330 drives the cutting shaft 320 to rotate clockwise. When it rotates to a certain position, under the action of gravity, the hardware plate 10 slides off the first elastic rod 321 onto the buffer ramp 312. It should be noted that during this process, one end of the first elastic rod 321 will come into contact with the sealing plate 311 and the buffer ramp 312 again. Because the first elastic rod 321 is elastic, it will bend and form an elastic deformation (such as...). Figure 10 As shown), therefore, the cut-off drive unit 330 can drive the cut-off shaft 320 to rotate smoothly in the forward direction without obstruction;

[0059] After the first elastic rod 321 has completely passed the sealing plate 311 and the buffer ramp 312, the first elastic rod 321 resumes its elastic deformation (as shown in the image). Figure 11 As shown), the cutting drive unit 330 will continue to drive the cutting shaft 320 to rotate forward, so that the second elastic rod 322 will eject the hardware plate 10 on the buffer ramp 312 into the drop chute 211 (as shown). Figure 12 As shown); it should be noted that, similarly to the first elastic rod 321, one end of the second elastic rod 322 bends upon contact with the sealing plate 311 and the buffer ramp 312. At this time, the second elastic rod 322 accumulates elastic potential energy. Since the second elastic rod 322 is located on the other side of the comb groove 11 (the hardware plate 10 blocks one end of the second elastic rod 322), after the second elastic rod 322 completely passes the sealing plate 311 and the buffer ramp 312, the second elastic rod 322 begins to release the accumulated elastic potential energy, ejecting the hardware plate 10 into the drop chute 211 (as shown). Figure 12 (as shown)

[0060] The push drive unit 230 drives the push rod 220 to push the metal plate 10 out of the discharge chute 211; after the metal plate 10 is ejected into the discharge chute 211, an impact occurs between the metal plate 10 and the side wall of the discharge chute 211, causing the metal plate 10 to not yet be accurately positioned. Therefore, as Figure 5 As shown, the pushing mechanism 200 also includes a guiding structure 240 located at one end of the dropping chute 211. The guiding structure 240 has a guiding groove 241. The guiding groove 241 and the sloping section of the dropping chute 211 form an inclined flared opening. It can be seen that even if the hardware plate 10 is not accurately in place, the hardware plate 10 can be adjusted in posture under the guidance of the guiding groove 241.

[0061] This completes the integrated operation of cutting and conveying a hardware panel 10.

[0062] like Figure 8 As shown, the cutting drive unit 330 continues to drive the cutting shaft 320 to rotate forward. As a result, one end of the first elastic rod 321 will pass through several clearance grooves 313 again and enter the outlet of the storage bin 110, forming a new cycle to cut off and transport the next hardware plate 10.

[0063] It should be emphasized that, for ease of description, the two sets of elastic rods in this invention are referred to as the first elastic rod 321 and the second elastic rod 322, respectively. In fact, the first elastic rod 321 and the second elastic rod 322 are interchangeable and can both achieve the same function.

[0064] In this invention, the cutting drive unit 330 only needs to drive the cutting shaft 320 to rotate forward or reverse to realize the integrated operation of quick cutting and ejection delivery of the hardware plate 10, which is convenient and fast.

[0065] The present invention also discloses a method for cutting and conveying metal sheets, based on the above-mentioned integrated cutting and conveying device 20 for metal sheets, comprising the following steps:

[0066] Step 1: Stack several metal plates in sequence and place them in the storage bin. The vibrator drives the metal plates toward the outlet of the storage bin.

[0067] Step 2: The cutting drive unit drives the cutting shaft to rotate forward, so that one end of several first elastic rods passes through several clearance grooves and enters the outlet of the storage bin, and one end of the first elastic rod hooks the comb groove of the foremost hardware plate.

[0068] Step 3: The cutting drive unit drives the cutting shaft to reverse, and one end of the first elastic rod cuts the foremost hardware piece out from the outlet of the storage bin.

[0069] Step four: The cutting drive unit drives the cutting shaft to rotate forward, and the hardware plate slides off the first elastic rod to the buffer ramp; in this step, one end of the first elastic rod contacts the sealing plate and the buffer ramp and bends.

[0070] Step 5: The cutting drive unit drives the cutting shaft to rotate forward, so that the second elastic rod ejects the hardware plate on the buffer ramp into the material drop chute; in this step, one end of the second elastic rod contacts the sealing plate and the buffer ramp and bends; when one end of the second elastic rod separates from the buffer ramp, the second elastic rod restores its elastic deformation, thereby ejecting the hardware plate on the buffer ramp into the material drop chute;

[0071] Step 6: The push drive unit drives the push rod to push out the metal sheet in the material chute;

[0072] Step 7: Repeat steps 2 through 6.

[0073] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
