Abstract
Description
Technical Field
[0001] This invention belongs to the field of automation equipment, specifically relating to an automatic material stamping and unloading tray device. Background Technology
[0002] like Figure 1 The material shown is a product processed by injection molding, stamping and other processes, including a sheet-shaped substrate 91 and a protrusion 92 protruding on one side of the substrate 91 in the thickness direction. One application of this material is as a positive electrode riveting block.
[0003] When used as metal parts, the above materials can be formed by stamping with a stamping press. Specifically, the flat base material is stamped and deformed to form protruding parts, and then the substrate is cut off from the base material by stamping and cutting, thereby completing the processing.
[0004] In addition, the processed materials fall onto the conveyor belt and are transported out and collected in the collection box. Then, the materials in the collection box are taken out one by one by manual means, and then the materials are flipped and adjusted by manual judgment so that the adjusted materials correspond to the placement slots in the pallet, thereby placing the materials in the pallet in an orderly manner.
[0005] The manual adjustment process usually involves two steps: first, flipping the plate so that the protrusion faces upward; and second, rotating it so that the circumferential orientation of the substrate corresponds to the circumferential orientation of the storage slot in the encoder, so that the material can be placed into the storage slot to complete the loading.
[0006] The problems with the above method are: 1. The high punching efficiency of the stamping machine requires a large number of people to screen and place the punched products on the pallet, which increases the cost. 2. The materials output from the conveyor belt will fall into the collection box under the action of gravity, and the materials will be worn and deformed due to collision and squeezing in the collection box, which increases the defect rate.

[0074] To enable those skilled in the art to better understand the present invention and to more clearly define the scope of protection of the present invention, the present invention will be described in detail below with reference to certain specific embodiments. It should be noted that the following are only some specific embodiments of the present invention, and are merely a part of the embodiments of the present invention. The specific and direct descriptions of related structures are only for the convenience of understanding the present invention, and the specific features do not necessarily or directly limit the scope of the present invention. Conventional choices and substitutions made by those skilled in the art under the guidance of the present invention should be considered within the scope of protection of the present invention.
[0075] Example 1:
[0076] like Figures 1-17 As shown, the present invention discloses an automatic material stamping and unloading tray device for stamping out material 9, sorting material 9, loading material 9 into a stacking tray 3, and loading stacking tray 3 into a material cart 8. The material 9 includes a square sheet-shaped substrate 91 and a protrusion 92 protruding on one side of the substrate 91 in the thickness direction. Among the four corners of the substrate 91, three are arc-shaped chamfers and one is inclined chamfer.
[0077] Specifically, the device includes:
[0078] A stamping press 1 is used to process materials 9 by stamping.
[0079] The forward and reverse feeding device 2 is used to organize the material 9 that is dropped from the stamping machine 1 during the transmission process so that the protrusion 92 is located above the substrate 91;
[0080] The code disk 3 is provided with a plurality of storage slots 31 for placing materials 9.
[0081] The frame 4 is provided with a first transfer station 41 and a second transfer station 42;
[0082] The switching turntable 5 is rotatably mounted on the frame 4. The switching turntable 5 is provided with two placement positions 51 for placing the code disk 3. The switching turntable 5 is used to switch each placement position 51 between the first transfer station 41 and the second transfer station 42.
[0083] The first transfer device 6 is used to transfer the material 9 that has been processed by the forward and reverse feeding device 2 to the storage slot 31 in the code disk 3 on the first transfer station 41, and to rotate and adjust the material 9 during the transfer process so that the circumferential orientation of the substrate 91 is adapted to the circumferential orientation of the storage slot 31.
[0084] Material cart 8, which is provided with 4 stacking positions 81 arranged in a matrix, for vertical stacking of pallets 3;
[0085] The second transfer device 7 is used to transfer the code disk 3 between the stacking position 81 and the second transfer station 42.
[0086] Therefore, the stamping machine 1 processes the material 9 through stamping, and the material 9 falls onto the forward and reverse feeding device 2. The material 9 is then adjusted during the transfer process of the forward and reverse feeding device 2, ensuring that the output material 9 has its protrusions 92 facing upwards. The first transfer device 6 then transfers the material 9 output from the forward and reverse feeding device 2 to the first transfer station 41, adjusting the circumferential orientation of the substrate 91 during the transfer process. This ensures that the material 9 transferred to the stack 3 is properly positioned within the storage cavity. Once all the storage cavities on the stack 3 are filled with material 9, the turntable 5 is rotated to transfer the stack 3 from the first transfer station 41 to the second transfer station 42. Finally, the second transfer device 7 transfers the loaded stack 3 to the material cart 8 to complete the unloading. The entire process—production, adjustment, turntable operation, and stacking—is fully automated, requiring no manual intervention. This results in high efficiency and low cost. Furthermore, the material 9 processed by the stamping machine 1 does not require an intermediate collection (loading into a collection box) process, preventing damage to the material 9.
[0087] Specifically, the forward and reverse feeding device 2 includes:
[0088] The conveying device 21 includes a mounting frame 211 and a conveyor belt 212. The conveyor belt 212 is mounted on the mounting frame 211 and is driven by a motor or other means to transport materials from left to right. The conveyor belt 212 is provided with a material handling area 213, a screening area 214 and a discharge area 215 in sequence above it along the transmission direction, so that the material 9 in contact with the conveyor belt 212 is transported through the material handling area 213, the screening area 214 and the discharge area 215 in sequence.
[0089] The material handling component 22 is located in the material handling area 213. Specifically, the material handling component 22 consists of two corresponding guide plates 221. Each guide plate 221 is bent to form an upper guide ramp 2211 and a lower guide straight plate 2212. The two guide ramps 2211 are inclined vertically upwards, moving away from each other in the front-back direction. This allows the material handling component 22 to form a collecting guide rail 222, which is downwardly tapered, thus collecting the material 9 falling from above. The normal of plate 2212 is perpendicular to the front-back direction, and its length is along the left-right direction. The distance between the two guide plates 2212 is s1, and the overall thickness of material 9 is s2. s1 = (1.0-1.1)s2, that is, s1 is slightly larger than s2. This makes the material handling component 22 form a vertical guide rail 223 by the two guide plates 2212. The width of the vertical guide rail 223 is adapted to the thickness of material 9 so that the thickness direction of material 9 entering the vertical guide rail 223 is along the width direction of the vertical guide rail 223. That is, the protrusion 92 of material 9 entering the vertical guide rail 223 faces forward or backward.
[0090] The forward and reverse detection device 23 can be a laser sensor, fiber optic sensor, etc., which is used to detect the material 9 in the vertical guide rail 223 to confirm the relative position of the protrusion 92 and the substrate 91.
[0091] A screening device is used to drive the material 9, which is output from the vertical guide rail 223 and enters the screening zone 214, to tilt.
[0092] Therefore, the material 9 processed by the stamping machine 1 falls from top to bottom into the collecting guide rail 222. The material 9 moves downward along the guide inclined plate 2211 towards the vertical guide rail 223. When the thickness direction of the material 9 is aligned with the width direction of the vertical guide rail 223, the material 9 is vertically guided into the vertical guide rail 223. That is, the thickness direction of the material 9 is along the front-to-back direction. After it has completely fallen, the lower end of the material 9 contacts the conveyor belt 212 and is then transported along the vertical guide rail 223 under the drive of the conveyor belt 212. When the reverse detection device 23 detects the protrusion 92 to determine whether it is located on the front or rear side of the substrate 91, it continues to be transported and leaves the vertical guide rail 223 to enter the screening area 214. The screening device is driven to perform different commands (implemented by the control system) on the materials 9 with different orientations of the protrusion 92, thereby driving the materials 9 to tilt and sort them in the screening area 214. Finally, the two groups of materials 9 that have been screened enter the discharge area 215 for discharge under the action of the conveyor belt 212, so that the output materials 9 all have the protrusion 92 facing upwards.
[0093] The mounting frame 211 features a U-shaped bracket 2111, on which the forward / reverse detection device 23 is mounted and faces downwards. As the material 9 is conveyed by the conveyor belt 212, it passes through the sensing area of the forward / reverse detection device 23, generating different light detection signals to determine whether the protrusion 92 has been detected. More specifically, the detection light generated by the forward / reverse detection device 23 is positioned close to the front-to-back width side of the vertical guide rail. When the protrusion 92 is located on this side and passes the forward / reverse detection device 23, the light signal generated by the detection light is only the duration of the protrusion 92 passing through the detection light, which is shorter. Conversely, when the protrusion 92 is away from this side and passes the forward / reverse detection device 23, the light signal generated by the detection light is the duration of the substrate 91 passing through the detection light, which is longer, thus enabling the determination.
[0094] In other embodiments, the front and back detection device 23 may employ a vision system, which can photograph each material 9 from top to bottom to determine the relative position of the protrusion 92 and the substrate 91, or take pictures from the front and back sides (the material handling component 22 may be transparent).
[0095] The screening device includes a drive component 24.
[0096] The driving component 24 can be either an air-blowing structure or a pushing structure. In this embodiment, an air-blowing structure is used, which consists of an air valve and an air nozzle. The air valve connects to the air source and controls the air nozzle to blow air, thereby driving the material 9 to tilt using air pressure. The pushing structure can be composed of a cylinder and a push rod. The cylinder drives the push rod to slide, thereby driving the material 99 to tilt by pushing.
[0097] In addition, the screening device also includes a partition plate 25 located in the screening area 214. The partition plate 25 has a first sub-area 251 and a second sub-area 252 on both sides. The driving member 24 is located on the side of the partition plate 25 facing the first sub-area 251. The driving member 24 blows air to tilt the material 9 output from the vertical guide rail 223 with the protrusion 92 facing the driving member 24 toward the second sub-area 252. After tilting, the protrusion 92 faces upward. The partition plate 25 is located on the movement trajectory of the material 9 with the protrusion 92 facing away from the driving member 24. This allows the material 9 output from the vertical guide rail 223 with the protrusion 92 facing away from the driving member 24 to move under the drive of the conveyor belt 212. After the substrate 91 enters the first sub-area 251, the corresponding protrusion 92 contacts one side of the partition plate 25, causing the material 9 to become unstable and tilt toward the first sub-area 251. After tilting, the protrusion 92 faces upward.
[0098] Therefore, by setting only a single driving component 24, the structure is simple. The driving component 24 only drives the material 9 with the protrusion 92 facing the driving component 24 to pour into the second sub-region 252, while the material 9 with the protrusion 92 facing away from the driving component 24 is poured into the first sub-region 251 under the action of the partition plate 25. This achieves that the protrusion 92 of the material 9 in the first sub-region 251 and the second sub-region 252 are all facing upwards. Moreover, the partition plate is a flat plate, which makes the structure simple.
[0099] The position of the driving member 24 is determined by the area of the substrate 91 (which has a relatively large mass). If the area of the substrate 91 is sufficient, the blowing position of the driving member 24 is close to the upper side of the substrate 91, so that when the blowing force pushes the material 9 away from the driving member 24, the material 9 is deflected and tilted.
[0100] If the area of substrate 91 is small (and its mass is relatively small), then the following structural-assisted tilting is required:
[0101] The screening device also includes a second limiting member 263 (plate-shaped) located in the second sub-region 252. The second limiting member 263 has a second inclined surface 264 on the side facing the partition plate 25. The inclined direction of the second inclined surface 264 is upward along the direction away from the partition plate 25.
[0102] Therefore, the smaller substrate 91 will be fully covered by the air blown by the drive member 24, that is, the material 9 is blown away from the drive member 24, but its tilting and flipping is unstable. Thus, with the setting of the second limiting member 263, the material 9 blown by the drive member 24 can tilt onto the second inclined surface 264 so that the protrusion 92 faces upward, and the material 9 slides downward under the action of gravity, thereby correcting the front and rear position of the material 9, making the position of the output material 99 more uniform.
[0103] Similarly, in this embodiment, a first limiting member 261 (plate-shaped) is provided in the first sub-region 251. The first limiting member 261 is provided with a first inclined surface 262 on the side facing the partition plate 25. The inclined direction of the first inclined surface 262 is upward along the distance away from the partition plate 25.
[0104] Therefore, the setting of the first limiting member 261 causes the material 9 poured in the first sub-region 251 to pour onto the second inclined surface 264, and under the action of gravity, the material 9 slides downward, thereby correcting the position of the material 9 in the front and back directions, making the position of the output material 9 more uniform.
[0105] Furthermore, in this embodiment, the discharge area 215 is provided with a first long strip 271, a second long strip 272, and a third long strip 273 along the front-back direction. The discharge area 215 is divided into a first discharge guide rail 2151 between the first long strip 271 and the second long strip 272, and a second discharge guide rail 2152 between the second long strip 272 and the third long strip 273. The first discharge guide rail 2151 corresponds to the first sub-area 251, and the second discharge guide rail 2152 corresponds to the second sub-area 252. The first discharge guide rail 2151 is used to receive material 9 from the first sub-area 251, so that the material 9 is laid flat and driven to be transported along the first discharge guide rail 2151. The second discharge guide rail 2152 is used to receive material 9 from the second sub-area 252, so that the material 9 is laid flat and driven to be transported along the second discharge guide rail 2152.
[0106] The attached structures are not shown in the figure. Only the suspended material handling component 22, partition plate 25, first limiting component 261, second limiting component 263, first long strip plate 271, second long strip plate 272 and third long strip plate 273 are shown. In fact, the aforementioned components are fixedly installed on the mounting frame 211, the stamping machine 1, the frame 4, or on other fixed structures using attached structures. The fixed material guiding structure on the conveying device 21 is a conventional technical means and will not be described in detail.
[0107] In addition, the frame 4 is equipped with a waste collector 281 and a waste collection frame 282. The waste collector 281 is located at the output end of the conveyor belt 212, so that the materials 9 produced when the machine is started do not need to be transferred through the first transfer device 6, but fall directly into the waste collector 281 and into the waste collection frame 282, so as to prevent defective products from being loaded into the pallet 3 among the materials 9 produced when the machine is started.
[0108] Specifically, the first transfer device 6 includes:
[0109] The vision device 61 is used to photograph the material 9 in the discharge area 215 and compare the photographed photo with the stored photo through the control system to determine the specific position of the three arc chamfers and one inclined chamfer to provide commands for subsequent rotation. The vision device 61 is a relatively mature technology, and the specific control method will not be described in detail.
[0110] The first pick-and-place component 62 is used to pick up and place material 9;
[0111] The first rotating component 63 is used to control the rotation of the first pick-up / placement component 62;
[0112] The first moving device 64 is used to control the movement of the first pick-and-place member 62 between the discharge area 215 and the storage trough 31.
[0113] Therefore, the first moving device 64 moves the first picking and placing member 62 to the discharge area 215 to pick up the corresponding material 9. The picked-up material 9 is photographed by the vision device 61. The internal judgment of the control system determines whether the material 9 needs to be rotated and how to rotate it. The command is executed by the first rotating member 63 so that the circumferential orientation of the adjusted material 9 is the same as the circumferential orientation of the storage trough 31, so that the material 9 can be smoothly placed into the storage trough 31.
[0114] Specifically, the number of the first pick-and-place components 62 is 5-10, and 9 are used in this embodiment. Each of the first pick-and-place components 62 is arranged in the left-right direction. Each of the first pick-and-place components 62 is equipped with a first rotating component 63 to achieve individual control. In addition, the first moving device 64 includes a first x-axis assembly 641, a first y-axis assembly 642, and a first z-axis assembly 643.
[0115] Specifically, the first x-axis assembly 641 includes a first x-axis sliding frame (left-right direction), a first x-axis sliding seat, and a first lead screw assembly (composed of a servo motor, a lead screw, and a nut). The first x-axis sliding frame is fixedly mounted on the frame 4, and the first x-axis sliding seat is slidably mounted on the first x-axis sliding frame. The first lead screw assembly is used to drive the first x-axis sliding seat to slide on the first x-axis sliding frame.
[0116] The first y-axis assembly 642 includes a first y-axis sliding frame (front-back direction), a first y-axis sliding seat, and a second lead screw assembly (composed of a servo motor, a lead screw, and a nut). The first y-axis sliding frame is disposed on the first x-axis sliding seat, and the first y-axis sliding seat is slidably mounted on the first y-axis sliding frame. The second lead screw assembly is used to drive the first y-axis sliding seat to slide on the first y-axis sliding frame.
[0117] The first z-axis assembly 643 includes a first z-axis sliding frame (vertical direction), a first z-axis sliding seat, and a first cylinder. The first z-axis sliding frame is disposed on the first y-axis sliding seat, and the first z-axis sliding seat is slidably mounted on the first z-axis sliding frame. The first cylinder is used to drive the first z-axis sliding seat to slide on the first z-axis sliding frame.
[0118] The vision device 61 is mounted on the first y-axis sliding frame;
[0119] Each of the first pick-and-place components 62 is mounted on the first z-axis sliding seat.
[0120] Therefore, during the process of the first x-axis component 641 driving the first pick-and-place component 62 to move toward the discharge area 215, the vision device 61 will be driven synchronously, enabling the vision device 61 to capture the material 9 on the discharge area 215 more quickly. Then, driven by the first y-axis component 642 and the first z-axis component 643, each of the first pick-and-place components 62 will pick up the material 9 respectively, realizing the transfer of multiple materials 9 in a single operation to improve efficiency.
[0121] The first moving device 64 (three-dimensional truss) is a mature technology. Only the structure of the first moving device 64 is disclosed, without the explanation of the specific operation process.
[0122] The first rotating component 63 is a rotary motor (fixedly mounted on the first z-axis sliding seat), and the output shaft of the rotary motor is vertical and internally through-type. The first pick-and-place component 62 includes an air seat 621, a floating tube 622, a floating spring 623, a limiting pin 624, and a suction cup 625. The air seat 621 is inserted into the output shaft of the rotary motor to be driven by the rotation of the first rotating component. The air seat 621 has a vertically penetrating air channel 6211, allowing the upper end to connect to an air tube for suction or blowing air to the lower end. The floating tube 622 is inserted into the air channel 6211 from the lower end of the air channel 6211 and can slide within it, with the floating tube 622 extending downwards from the air channel 6211. In addition, the outer peripheral wall of the air seat 621 is provided with a positioning insertion hole 6212 that penetrates to the air channel 6211. The outer peripheral wall of the floating tube 622 is correspondingly provided with a positioning guide rail 6221 that extends along the axial direction of the floating tube 622. The positioning insertion hole 6212 and the positioning guide rail 6221 are inserted by the limiting pin 624 to limit the vertical sliding stroke of the floating tube 622 relative to the air seat 621. In addition, the suction cup 625 is provided below the floating tube 622 by snap-fitting. The center of the suction cup 625 is provided with a suction port 6251 that communicates with the channel inside the floating tube 622. The floating spring 623 is compressed and provided between the air seat 621 and the floating tube 622 to reset the floating tube 622 downward.
[0123] Therefore, when the first pick-up and drop-off member 62 moves above the material 9, the suction cup 625 presses onto the upper surface of the material 9, and the material 9 is stably sucked onto the suction cup 625 by suction. After moving to the position, the material 9 is blown away from the suction cup 625. In addition, the floating tube 622 and the floating spring 623 make the stroke elastically adaptable when picking up the material 9, improving the smoothness of picking up.
[0124] In this embodiment, the two placement positions 51 are one on the left and one on the right. The rotation of the switching turntable 5 can enable the placement positions 51 on the left and right sides to be interchanged, so as to switch between the first transfer station 41 (left side) and the second transfer station 42 (right side).
[0125] Preferably, each of the placement positions 51 is provided with two tray positions 511, and the four tray positions 511 on the switching turntable 5 are arranged in a matrix. Correspondingly, the stamping machine 1 can stamp two pieces of material 9 simultaneously, with a front-to-back interval. Similarly, the material handling component 22, the forward and reverse detection device 23, the screening device, the first Z-axis assembly 643, the first pick-and-place component 62, and the first rotating component 63 are all in two sets, so that two production lines can process material 9 to improve production efficiency. Each production line corresponds to one tray position 511, and each tray position 511 can be used to place the stacking tray 3. In addition, a rotary cylinder 52 (rotatable and height-adjustable) is provided between adjacent tray positions 511. The output shaft of the rotary cylinder 52 is vertically upward, and a horizontally extending linkage rod 53 is provided above the output shaft of each rotary cylinder 52. The middle of the linkage rod 53 is connected by a snap-fit method. Fixed to the output shaft of the rotary cylinder 52, each of the linkage rods 53 has a vertically downward extending locking rod 54 fixed at both ends. Correspondingly, each of the four corner ends of the encoder 3 is provided with a locking hole 32. Therefore, during the switching of the turntable 5 rotation or the placement of material 9 on the encoder 3, the locking rod 54 is inserted into the locking hole 32 for fixation, ensuring the stability of the encoder 3. Specifically, each encoder 3 is subject to the insertion of two locking rods 54. When the encoder 3 needs to be transferred, the output shaft of the rotary cylinder 52 moves upward to disengage the locking rod 54 from the locking hole 32, and then rotates 90 degrees so that the length direction of the linkage rod 53 is perpendicular to the direction of the corresponding two encoders 3. This allows the linkage rod 53, locking rod 54 and encoder 3 to be misaligned during the vertical lifting of the encoder 3, so that it can be smoothly lifted and put down.
[0126] Specifically, the second transfer device 7 in this embodiment includes:
[0127] The second y-axis assembly 72 includes a second y-axis sliding frame (front-back direction), a second y-axis sliding seat, and a first rack assembly (composed of a servo motor, rack, and gear). The second y-axis sliding frame is fixedly mounted on the frame 4, and the second y-axis sliding seat is slidably mounted on the second y-axis sliding frame.

[0128] The second x-axis assembly 71 includes a second x-axis sliding frame (left-right direction), a second x-axis sliding seat, and a second rack assembly (composed of a servo motor, rack, and gear). The second x-axis sliding frame is disposed on the second y-axis sliding seat, and the second x-axis sliding seat is slidably mounted on the second x-axis sliding frame. The second rack assembly is used to drive the second x-axis sliding seat to slide on the second x-axis sliding frame.
[0129] The second z-axis assembly 73 includes a second z-axis slide frame and a third rack assembly (composed of a servo motor, rack, and gear). The second z-axis slide frame is slidably mounted on the second x-axis slide seat. The third rack assembly is used to drive the second z-axis slide frame to slide on the second x-axis slide frame.
[0130] The second pick-and-place component 74 is used to pick up and place the code disk 3, and the second pick-and-place component 74 is disposed below the second z-axis sliding frame.
[0131] Therefore, under the action of the second x-axis assembly 71, the second y-axis assembly 72, and the second z-axis assembly 73, the second pick-and-place component 74 is driven in three directions (x, y, z), and after it is in place, it performs a grabbing and releasing action to transfer the code disk 3.
[0132] The second x-axis assembly 71, the second y-axis assembly 72, and the second z-axis assembly 73 employ a driving and sliding method for unidirectional sliding drive, which is a mature technology. Only a simple structural description of the second x-axis assembly 71, the second y-axis assembly 72, and the second z-axis assembly 73 is disclosed, without a description of the specific operation process.
[0133] Specifically, in this embodiment, the second pick-and-place component 74 includes a gripper seat 741, a retractable sliding seat 742, and a retractable cylinder 743. A retractable slide rail 7411 extending laterally is provided below the gripper seat 741. There are two retractable sliding seats 742, each slidably mounted on the retractable slide rail 7411. Each retractable sliding seat 742 has two claw portions 7421 (L-shaped). There are two retractable cylinders 743, each mounted on the gripper seat 741. One of the retractable cylinders 743 has its output shaft facing left and is fixedly connected to the left-side retractable sliding seat 742 for sliding drive. The output shaft of a retractable cylinder 743 is fixedly connected to the right retractable sliding seat 742 for sliding drive. Two buffers 744 are respectively provided on the gripper seat 741 corresponding to each retractable sliding seat 742. The buffer 744 includes a buffer head 7441, which plays a buffering role when the corresponding retractable sliding seat 742 is retracted. Elastic members 745 are respectively provided on the front and rear sides of the gripper seat 741. The elastic members 745 are made of rubber and are vertically downward, so that when the second pick-up and put-down component 74 grips the code disk 3, the lower end of each elastic member 745 abuts against the upper end of the code disk 3 to tighten the code disk 3.
[0134] Preferably, there are two material carts 8, which are arranged front and back on both sides of the frame 4 to carry out the orderly stacking of a large number of pallets 3.
