Description

Technical Field

[0001] This disclosure relates to equipment for processing stamped long materials, and more particularly to a long material top breakage detection and packaging equipment. Background Technology

[0002] Currently, in the production process of precision electronic products, some long stamped products, such as long strips of steel, are formed on the production line. These long products also require the transfer of corresponding films or adhesive sheets. The long products need to be cut from the strip, and their flatness and overall appearance need to be inspected to determine if they are defective or not. Qualified long products are then packaged and stored. However, the traditional method involves manual inspection of bulk materials, manually judging whether products are defective or not, manually rejecting defective products, and placing qualified products on carrier belts for packaging. This process is labor-intensive, inefficient, inaccurate, has a high error rate, low product yield, requires a large workforce, and is costly. Existing equipment also suffers from inconvenient operation, low efficiency, low accuracy, and low stability and reliability, thus failing to meet increasingly demanding production requirements. Summary of the Invention

[0003] The purpose of this disclosure is to provide a long material breakage detection and packaging device, which can solve at least one of the above-mentioned technical problems. The technical solution of this disclosure is as follows:

[0008] In some embodiments, the material pulling device includes a first support, on which two first pressing components, a positioning pressing and pulling component, and a first driving mechanism are disposed. The two first pressing components and the positioning pressing and pulling component are disposed along the conveying direction of the material belt. The positioning pressing and pulling component is located between the two first pressing components. The two first pressing components can press the material belt to position it. After the positioning pressing and pulling component positions and presses the material belt, the two first pressing components release the material belt. The first driving mechanism can drive the positioning pressing and pulling component to reciprocate linearly to pull the material.

[0009] In some embodiments, the first picking and placing device includes a first robotic arm and a first variable-pitch suction assembly. The first robotic arm is connected to the first variable-pitch suction assembly, and the first robotic arm drives the first variable-pitch suction assembly to move so that the first variable-pitch suction assembly picks up and places products.

[0010] In some embodiments, the first variable-pitch suction assembly includes a second bracket, on which a first guide rod, a scissor fork mechanism, a second drive mechanism, and at least two first variable-pitch plates arranged sequentially along the first guide rod are mounted. One end of the first variable-pitch plate is fixed, while the remaining first variable-pitch plates are slidably connected to the first guide rod. The first variable-pitch plate at the end away from the fixed first variable-pitch plate is connected to the second drive mechanism. Each intersection of the scissor fork mechanism is connected to each of the first variable-pitch plates. The first variable-pitch plate is provided with a first suction nozzle for suctioning products. The second drive mechanism drives the first variable-pitch plate connected to it to slide along the first guide rod. The first variable-pitch plate connected to the second drive mechanism drives the remaining first variable-pitch plates to slide along the first guide rod to change pitch through the scissor fork mechanism.

[0011] In some embodiments, the first feeding plate is provided with an adjustable pressure roller assembly for cooperating with the material belt. The adjustable pressure roller assembly includes a first pressure roller, a first swing block, a first adjusting plate, and a first elastic element. The first pressure roller is mounted on the first swing block, which is hinged to the first feeding plate. The first adjusting plate is mounted on the first feeding plate and is located on one side of the first swing block. The position of the first adjusting plate can be adjusted and locked. The first swing block and the first adjusting plate are connected by the first elastic element. Under the action of the first elastic element, the first swing block elastically presses against the first adjusting plate. Adjusting the position of the first adjusting plate can drive the first swing block to rotate.

[0012] In some embodiments, a first screw post is provided at one end of the first swing block, and a first connecting shaft connected to the first pressure roller is provided at the other end of the first swing block. The first screw post is hinged to the first swing block and threadedly connected to the first feeding plate.

[0014] The beneficial effects of this disclosure are as follows: During use, after the long material product is processed on the conveyor belt, the pulling device pulls the conveyor belt through the first feeding plate and the breaking device in sequence. The lower detection device below the first feeding plate detects the lower surface of the product on the conveyor belt, and the upper detection device above the first feeding plate detects the upper surface of the product on the conveyor belt, checking for defects such as misalignment or missing parts. Then, the breaking device breaks the product off the conveyor belt after the appearance inspection. The first pick-and-place device then picks up the broken product from the breaking device and places it onto the flatness detection device, which checks whether the flatness of the product is qualified. Based on the test results, the first pick-and-place device picks up qualified products from the flatness detection device and places them onto the automatic tray changing device for packaging and stacking. Conversely, the first pick-and-place device picks up unqualified products from the flatness detection device and places them at the corresponding positions for collection. This process achieves the breaking, testing, and packaging of long products. The operation is simple and convenient, with low labor intensity, saving manpower and resources. It is highly efficient, precise, and less prone to misjudgment, thereby improving production efficiency, product quality, and yield. It also boasts high stability and reliability, facilitating production control and automated production lines, reducing costs, and meeting increasingly demanding production requirements.

[0031] See Figures 1-10 The diagram schematically illustrates a long material breakage detection and packaging equipment according to the present disclosure, including a frame 1. The frame 1 is equipped with a first feeding plate 11, a breakage detection device 12, a pulling device 2, an upper detection device 3, a lower detection device 4, a first pick-and-place device 5, a flatness detection device 6, and an automatic tray changing device 7. The upper detection device 3 is located above the first feeding plate 11, and the lower detection device 4 is located below the first feeding plate 11. The first feeding plate 11, the breakage detection device 12, and the pulling device 2 are typically arranged sequentially. The first pick-and-place device 5 corresponds and cooperates with the breakage detection device 12, the flatness detection device 6, and the automatic tray changing device 7, respectively. The pulling device... 2 is used to pull the conveyor belt through the first feeding plate 11 and the breaking device 12 in sequence. The breaking device 12 is used to break the product off the conveyor belt. The first picking and placing device 5 is used to pick up the broken product and place it on the flatness detection device 6. The first picking and placing device 5 can pick up qualified products from the flatness detection device 6 and place them on the automatic tray changing device 7 for packaging and stacking. The first picking and placing device 5 can also pick up unqualified products from the flatness detection device 6 and place them in the corresponding position for collection. The automatic tray changing device 7 can place empty trays one by one and can collect and stack trays full of products in sequence.

[0032] During use, after the long material product is processed on the conveyor belt, the pulling device 2 pulls the conveyor belt through the first feeding plate 11 and the breaking device 12 in sequence. The lower detection device 4 below the first feeding plate 11 detects the lower surface of the product on the conveyor belt, and the upper detection device 3 above the first feeding plate 11 detects the upper surface of the product on the conveyor belt, checking for defects such as misalignment or missing parts. Then, the breaking device 12 breaks the product off the conveyor belt after the appearance inspection. The first pick-up and drop device 5 then picks up the broken product from the breaking device 12 and places it onto the flatness detection device 6. The flatness detection device 6 checks whether the flatness of the product is qualified. Based on the test results, the first picking and placing device 5 picks up qualified products from the flatness detection device 6 and places them onto the automatic tray changing device 7 for packaging and stacking. The first picking and placing device 5 also picks up unqualified products from the flatness detection device 6 and places them into the corresponding positions for collection. The automatic tray changing device 7 places empty trays one by one and then collects and stacks trays full of products in sequence. This realizes the integrated production and processing of automatic cutting, detection and packaging of long products. The operation is simple and convenient, with low labor intensity, saving manpower and material resources, high efficiency, high precision, and less prone to misjudgment. It is also convenient for production control and automated production line production.

[0033] The upper surface of the first feeding plate 11 is provided with a first groove 111 for the material belt to pass through. The bottom surface of the first groove 111 is provided with a first clearance through hole 112 corresponding to the lower detection device 4, making the structure more compact and stable. Pressure plates that cooperate with the sides of the material belt can also be provided on the upper sides of the first groove 111, facilitating better conveying of the material belt along the first groove 111, making it more stable and reliable. The frame 1 is provided with a first support seat 17 that cooperates with the first feeding plate 11, making operation more convenient. The number and arrangement of the first support seats 17 depend on the specific situation.

[0034] The first feeding plate 11 is provided with an adjustable pressure roller assembly 16 for cooperating with the material belt. The adjustable pressure roller assembly 16 includes a first pressure roller 161, a first swing block 162, a first adjusting plate 163, and a first elastic element 164. The first pressure roller 161 is mounted on the first swing block 162, and the first swing block 162 is hinged to the first feeding plate 11 so that the first swing block 162 can rotate. The first adjusting plate 163 is mounted on the first feeding plate 11 and is located on one side of the first swing block 162. The position of the first adjusting plate 163 can be adjusted and locked. The first swing block 162 and the first adjusting plate 163 are connected by the first elastic element 164. In operation, the first adjusting plate 163 remains stationary. Under the action of the first elastic element 164, the first swing block 162 elastically presses against the first adjusting plate 163. For example, the first swing block 162 can be tilted and pressed against one end of the first adjusting plate 163. The first pressure roller 161 elastically presses against the conveyor belt on the first feeding plate 11, ensuring that the conveyor belt adheres to the first feeding plate 11 for safer and more reliable conveying. When it is necessary to adjust the pressure of the first pressure roller 161 on the conveyor belt or to change to a conveyor belt of different specifications, the first adjusting plate 163 is moved first. Under the action of the first elastic element 164, as the first adjusting plate 163 moves, the first swing block 162 rotates against the first adjusting plate 163. After the first swing block 162 rotates to the appropriate position, the first adjusting plate 163 is locked with screws or other fasteners to ensure that the first pressure roller 161 better holds the conveyor belt. This method is convenient to operate and has a wide range of applications. The first pressure roller 161 can also be made of nylon or other materials to reduce damage to the conveyor belt.

[0035] One end of the first swing block 162 is provided with a first screw post 165, and the other end of the first swing block 162 is provided with a first connecting shaft 166 connected to the first pressure roller 161. The first screw post 165 is hinged to the first swing block 162 and threadedly connected to the first feeding plate 11. The first swing block 162 is provided with a connecting hole for connecting to the first screw post 165, making operation more convenient and the structure more stable.

[0036] The first adjusting plate 163 has a first elongated hole at one end away from the first swing block 162. The first adjusting plate 163 is moved to a suitable position, and then fasteners such as screws are used to pass through the first elongated hole and threadedly connect with the first feeding plate 11 to lock it, thereby adjusting the position of the first adjusting plate 163.

[0037] The first elastic element is a spring, such as a tension spring. The first adjusting plate 163 has a first connecting post at one end near the first swing block 162, which connects to one end of the first elastic element 164. The first swing block 162 has a second connecting post connecting to the other end of the first elastic element 164. Hooks can be provided at both ends of the tension spring, and grooves can be provided on the connecting posts to engage with the hooks, making operation simpler and more convenient. The first adjusting plate 163 has a first arc surface at one end near the first swing block 162, which engages with the first swing block 162, allowing the first swing block 162 to better elastically press against the first adjusting plate 163.

[0038] The frame 1 may also be equipped with a guide assembly that cooperates with the first feeding plate 11. The guide assembly can guide the material belt to ensure that the material belt is better conveyed along the first feeding plate 11 and prevent the material belt from running off-track. The guide assembly may include a guide roller with two side guards. The first material belt passes through the guide roller between the two side guards.

[0039] The material pulling device 2 includes a first support 21, on which two first pressing components 22, a positioning pressing and pulling component 23, and a first drive mechanism 24 are arranged. The two first pressing components 22 and the positioning pressing and pulling component 23 are arranged along the conveying direction of the material belt. The positioning pressing and pulling component 23 is located between the two first pressing components 22. The first drive mechanism 24 is connected to the positioning pressing and pulling component 23. The first drive mechanism 24 can drive the positioning pressing and pulling component 23 to reciprocate linear motion. The first drive mechanism 24 can be a cylinder, hydraulic cylinder, electric cylinder, screw mechanism, linear module, etc. For example, using a linear module is more precise and stable. During material pulling, the two first pressing components 22 first press the material strip to position it, and the positioning pressing and pulling component 23 then positions and presses the material strip again. Then, the two first pressing components 22 release the material strip, and the first drive mechanism 24 drives the positioning pressing and pulling component 23 to move linearly one station distance, so that the positioning pressing and pulling component 23 stably pulls the material strip forward one station. Then, the two first pressing components 22 press the material strip to position it again. After the positioning pressing and pulling component 23 releases the material strip, the first drive mechanism 24 drives the positioning pressing and pulling component 23 back to the initial position, and then the next material pulling is performed. This material pulling process is continuously repeated, thereby realizing automatic positioning and precise material pulling. The structure is simple, the material pulling accuracy is high, and it is not easy to cause problems such as material strip arching and shifting to the middle, material strip deformation and damage, and material strip movement and jamming during the material pulling process. It can better pull the material strip of large frame products.

[0040] The first material pressing assembly 22 includes a first material support plate for the material strip to pass through, a first pressure plate located above the first material support plate, and a first lifting mechanism that pushes the first pressure plate to move up and down. The material strip passes through the first material support plate from below the first pressure plate. The positioning and pressing assembly 23 includes a first support, and a first drive mechanism 24 that can drive the first support to reciprocate linearly. The first support is provided with a second material support plate for the material strip to pass through, a second pressure plate located above the second material support plate, and a second lifting mechanism that pushes the second pressure plate to move up and down. The material strip passes through the second material support plate from below the second pressure plate. The first and second lifting mechanisms can be made of cylinders, hydraulic cylinders, electric cylinders, lead screw mechanisms, linear modules, etc. For example, using a cylinder has a simple and compact structure, is easy to install and maintain, and is safe and environmentally friendly.

[0041] The first material handling device 5 includes a first robotic arm 51 and a first variable-pitch suction assembly 52. ​​The first robotic arm 51 can be a translational robotic arm, a fast cam transport robotic arm, a swing arm robotic arm, a six-axis robotic arm, etc. The first robotic arm 51 is connected to the first variable-pitch suction assembly 52. ​​The first robotic arm 51 drives the first variable-pitch suction assembly 52 to move, so that the first variable-pitch suction assembly 52 picks up and places products according to specific needs.

[0042] like Figure 8 , 9As shown, the first variable-pitch suction assembly 52 includes a second bracket 525. The second bracket 525 is equipped with a first guide rod 522 arranged side-by-side, a scissor fork mechanism 523, a second drive mechanism 524, and four first variable-pitch plates 521 arranged sequentially along the first guide rod 522. One end of the first variable-pitch plate 521 is fixed, while the other three first variable-pitch plates 521 are slidably connected to two first guide rods 522. The first variable-pitch plate 521 at the end furthest from the fixed first variable-pitch plate 521 is connected to the second drive mechanism 524. Each intersection of the scissor fork mechanism 523 is connected to a first variable-pitch plate 521. The first variable-pitch plate 521 is equipped with a first suction nozzle 526 for picking up products. The number and arrangement of the first suction nozzles 526 on the first variable-pitch plate 521 are determined according to specific circumstances, but there are at least two first variable-pitch plates 521. The number and arrangement of the first variable-pitch plates 521 and the first guide rods 522 can be appropriately increased or decreased depending on specific circumstances. The second drive mechanism can be a pneumatic cylinder, electric cylinder, hydraulic cylinder, linear module, etc. During use, the second drive mechanism 524 drives the first variable-pitch plate 521 connected to it to slide along the two first guide rods 522. The first variable-pitch plate 521 connected to the second drive mechanism 524 drives the other three first variable-pitch plates 521 to slide along the first guide rods 522 through the scissor fork mechanism 523, thereby changing the distance between the four first variable-pitch plates 521. This facilitates the adjustment of the distance between the four picked-up products according to actual needs, and then sequentially places them into the tray of the automatic tray changing device 7, making operation more convenient and efficient. The second support 525 is also provided with a first chuck 527 and a first connecting seat 528. The first chuck 527 is connected to the first robotic arm 51, and the first connecting seat 528 is connected to the output end of the first drive mechanism 24.

[0043] like Figure 9 As shown, the scissor fork mechanism 523 includes eight variable-pitch long links, which are sequentially hinged to form four intersections. The four intersections can be connected to four first variable-pitch plates 521 respectively through connecting parts such as pins. By changing the size of the intersection angle, the distance between two adjacent intersections can be changed, thereby realizing variable pitch.

[0044] The flatness testing device 6 includes a first fixture plate 61 and a first detector 62 located below the first fixture plate 61. The first fixture plate 61 is provided with a first positioning groove 611 for placing the product. The first positioning groove 611 is provided with a second clearance through hole 612 corresponding to the first detector 62. The first detector 62 can be a 3D area array camera. The 3D area array camera scans the flatness of the product in the first positioning groove 611 to detect whether the flatness of the product is qualified, which is more accurate and reliable. The shape, number and arrangement of the first positioning groove 611 are determined according to the specific situation. Guide posts can also be provided around the first positioning groove 611 to facilitate the product to be placed in the first positioning groove 611 better. Support blocks for cooperating with the product can also be provided around the bottom of the second clearance through hole 612. The first detector 62 can also be a CCD camera, a line laser instrument, a 3D scanner, a three-dimensional intelligent sensor or other suitable testing mechanism.

[0045] The upper detection device 3 and the lower detection device 4 have basically the same structure. The upper detection device 3 and the lower detection device 4 are common mechanisms in the prior art. For example, they can be detected by taking pictures with a camera. The camera is mounted on a corresponding bracket. The camera can be a CCD camera, etc. The bracket can also be equipped with a light source that works with the camera, a slide table for adjusting the camera position, a linear module, etc. The camera can also be a line laser instrument, a 3D scanner, a 3D area array camera, a three-dimensional intelligent sensor, etc. The light source can be a coaxial light source, a ring light source, a strip light source, a lamp light source, a backlight source, a surface light source, etc.

[0046] To improve efficiency and ease of operation, the frame 1 is also equipped with a second material handling device 13, a waste material box 14, and a cutting die 15. The second material handling device 13 has a structure that is basically the same as the first material handling device 5. The second material handling device 13 is used to pick up and place the products that have been broken off from the breaking device 12 onto the flatness detection device 6. The first material handling device 5 is used to pick up and place qualified products from the flatness detection device 6 onto the automatic tray changing device 7, and to pick up unqualified products from the flatness detection device 6 into the waste material box 14. This makes the operation more convenient and the efficiency higher. The first feeding plate 11, the breaking device 12, the pulling device 2, and the cutting die 15 are arranged in sequence. The cutting die 15 is used to cut the waste strip according to requirements. The end of the cutting die 15 away from the pulling device 2 is provided with a first discharge chute 151. The first discharge chute 151 facilitates the discharge of the cut waste strip. The outlet of the first discharge chute 151 can also be connected to a collection box. The top-cutting device 12 and the cutting mold 15 are common mechanisms in the prior art. For example, the top-cutting device 12 and the cutting mold 15 are respectively equipped with a cutter and a drive mechanism for driving the cutter to move and cut. The drive mechanism can be a hydraulic cylinder, a pneumatic cylinder, etc.

[0047] The automatic tray changing device 7 is a common mechanism in the prior art and will not be described in detail here. Typically, the automatic tray changing device 7 includes a tray dropping assembly, a tray receiving assembly, a tray dispensing and transferring assembly, and a tray positioning assembly. The tray dropping assembly places empty trays one by one onto the tray dispensing and transferring assembly. The tray dispensing and transferring assembly first moves the empty trays to the tray packaging station. The tray positioning assembly positions the empty trays. After the first picking and placing device 5 fills the empty trays with qualified products, the tray dispensing and transferring assembly moves the trays filled with products to the position corresponding to the tray receiving assembly. The tray receiving assembly then stacks the trays filled with products together in sequence.

[0048] The frame 1 can be equipped with a protective cover 18, an electrical cabinet, an external vacuum pump 19, etc., all of which are located within the protective cover 18.
