[0002] Material handling robots are specialized robots used in industrial automation for material handling. Through robotic arms and end effectors, they automatically complete the entire process from picking up raw materials from the feeding point, clamping them onto processing equipment (such as machine tools), and then unloading the finished products to a designated location. These robots can efficiently replace manual labor, enabling automated and continuous material handling on production lines, significantly improving production efficiency and stability, and are one of the core pieces of equipment in smart factories.

[0010] Preferably, four mounting blocks are fixedly installed on the outer surface of the material box, and several rollers are rotatably installed in the inner cavity of each mounting block. A steel cable is installed between two adjacent rollers for transmission. A first motor is fixedly installed on one side of each mounting block, and a connecting shaft is fixedly connected to the output shaft of the first motor. The connecting shaft is fixedly connected to the rollers.

[0011] Preferably, a second mounting bracket is fixedly installed on one side of the material box, and transmission rollers are rotatably installed on both the second mounting bracket and the inner cavity of the material box, and the conveyor belt is wound and installed on the outer surface of the two transmission rollers.

[0012] Preferably, a sixth motor is fixedly mounted on one side of the second mounting bracket, and the output shaft of the sixth motor is fixedly connected to the transmission roller.

[0013] Preferably, a first support plate is fixedly installed in the inner cavity of the material box. The first support plate and the second support plate are located in the inner cavity and bottom of the conveyor belt, respectively. A plurality of second electric telescopic rods are fixedly installed in the inner cavity of the material box. The plurality of second electric telescopic rods are divided into two groups, and the output ends of the two groups of second electric telescopic rods are fixedly connected to two bearing plates, respectively.

[0014] Preferably, the inner cavity of the material box has two second grooves, the mounting plate is slidably installed in the inner cavity of the second groove, a threaded rod is rotatably installed in the inner cavity of the second groove, the threaded rod is threadedly connected to the mounting plate, one end of the threaded rod is fixedly connected to a fourth motor, and the fourth motor is fixedly installed on one side of the material box.

[0015] Preferably, the inner cavity of the second groove has two third grooves, and a limiting block is slidably installed in the inner cavity of the third groove. Both limiting blocks are fixedly connected to the mounting plate.

[0016] Preferably, the bottom of the mounting plate is fixedly mounted on the guide rail, a linear motor is slidably mounted inside the guide rail, a fifth motor is fixedly mounted at the bottom of the linear motor, and the output shaft of the fifth motor is fixedly connected to the lever.

[0017] The advantages of this invention are: 1. This invention uses a multi-axis robotic arm to move a first mounting frame to the top of the material. A second motor output shaft drives a bidirectional threaded rod to rotate, which, in conjunction with a sliding rod, limits the first clamping plate, causing the two clamping plates to move closer together and clamp the material. During the material transfer process, a third motor output shaft drives a gear to rotate, which further drives a gear ring to rotate within the limiting sleeve cavity. As the gear ring rotates, it also drives a detection rod to rotate. At this time, the material is within the rotation range of the detection rod. By making the gear ring rotate around the detection rod, the detection rod can detect the entire exterior of the material. Then, the multi-axis robotic arm transfers the material to the top of the conveyor belt. For qualified and unqualified materials, a lever is used to move them to the top of the two bearing plates respectively, thereby classifying the materials. Unqualified materials are collected for further processing, while qualified materials can be taken out from the material box cavity by the multi-axis robotic arm for the next process.

[0018] 2. This invention allows the second electric telescopic rod to extend and move the support plate upwards, bringing the top of the support plate to the same horizontal plane as the top of the conveyor belt. This facilitates the lever to move the material from the top of the conveyor belt to the top of the support plate, and also facilitates the movement of material from the top of the support plate to the top of the conveyor belt. During use, the first support plate supports the conveyor belt, preventing the material from being unable to slide between the conveyor belt and the support plate due to the belt's elasticity after it is placed on top. The second support plate divides the inner cavity of the material box into two parts, thus clearly separating qualified and unqualified materials.

[0019] 3. In this invention, the output shaft of the fourth motor drives the threaded rod to rotate, which, in conjunction with the two limiting blocks, slides within the third groove cavity, thereby limiting the movement of the limiting blocks. The limiting blocks can only slide along the inner cavity of the third groove. When the mounting plate slides to the material side, the linear motor slides along the guide rail, driving the lever to the material side. The output shaft of the fifth motor drives the lever to rotate, increasing the contact area between the lever and the material. The linear motor then drives the lever to slide, which can move the material. When the linear motor moves the lever, the lever is in a horizontal state, which can prevent the material from affecting the sliding of the lever. Attached Figure Description

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figures 1 to 7 As shown, an intelligent loading and unloading robot includes a material bin 1, a conveyor belt 35 rotatably mounted inside the material bin 1, a multi-axis robotic arm 2 rotatably mounted on the top of the material bin 1, a second support plate 41 fixedly mounted inside the material bin 1, and bearing plates 43 slidably mounted on both sides of the second support plate 41; it also includes a sorting mechanism for sorting materials; the sorting mechanism includes a first mounting frame 21, which is fixedly mounted on one end of the multi-axis robotic arm 2, a slide rod 22 and a bidirectional threaded rod 221 rotatably mounted inside the first mounting frame 21, a second motor 222 fixedly connected to one end of the bidirectional threaded rod 221, two first clamping plates 23 threadedly connected to the outer surface of the bidirectional threaded rod 221, both of the first clamping plates 23 being slidably connected to the slide rod 22, a toothed ring 241 rotatably mounted inside the first mounting frame 21, a detection rod 242 fixedly mounted on one side of the toothed ring 241, an mounting plate 51 slidably mounted inside the material bin 1, and a lever 57 rotatably mounted on the bottom of the mounting plate 51; A limiting sleeve 24 is fixedly installed on one side of the first mounting bracket 21, and the gear ring 241 is rotatably installed in the inner cavity of the limiting sleeve 24. A third motor 244 is fixedly installed on one side of the first mounting bracket 21, and a gear 243 is fixedly connected to the output shaft of the third motor 244. The gear 243 meshes with the gear ring 241.

[0025] Existing loading and unloading robots cannot detect the quality of materials during the material handling process, which ultimately leads to qualified and unqualified materials being mixed together and difficult to separate.

[0026] In use, this invention first moves the first mounting bracket 21 to the top of the material via a multi-axis robotic arm 2. Then, the output shaft of the second motor 222 rotates the bidirectional threaded rod 221, which, in conjunction with the sliding rod 22, limits the movement of the first clamping plates 23, causing them to move closer together and clamp the material. During material transfer, the output shaft of the third motor 244 rotates the gear 243, which further drives the gear ring 241 to rotate within the limiting sleeve 24. As the gear ring 241 rotates, it also rotates the detection rod 242. At this point, the material is within the rotation range of the detection rod 242. By causing the gear ring 241 to rotate... The rotating detection rod 242 allows it to inspect the entire exterior of the material. Then, the multi-axis robotic arm 2 transfers the material to the top of the conveyor belt 35. For qualified and unqualified materials, the lever 57 moves them to the top of the two support plates 43 respectively, thus classifying the materials. Unqualified materials are collected for further processing, while qualified materials can be taken out from the inner cavity of the material box 1 by the multi-axis robotic arm 2 to enter the next process. The detection rod 242 is a rod with a detector installed on its outer surface. When the detection rod 242 rotates, the detector can scan and inspect the material.

[0027] Furthermore, such as Figure 4 As shown, the first clamping plate 23 has a first groove 231 at the bottom, a slide plate 233 is slidably installed in the inner cavity of the first groove 231, a second clamping plate 234 is fixedly connected to the bottom of the slide plate 233, a first electric telescopic rod 232 is fixedly installed in the inner cavity of the first groove 231, and the output end of the first electric telescopic rod 232 is fixedly connected to the slide plate 233.

[0028] In use, to prevent the material from affecting the circumferential movement of the detection rod 242 after the first clamping plate 23 clamps the material, the first electric telescopic rod 232 extends its output end to slide the slide plate 233 into the inner cavity of the first groove 231. The first groove 231 then moves the second clamping plate 234 to both sides of the material. Then, the two first clamping plates 23 approach each other to clamp the material. The output ends of the two first electric telescopic rods 232 then shorten synchronously to lift the material. This method can both clamp the material and prevent the material volume from being too large and affecting the detection rod 242's detection of the material. At the same time, the first clamping plate 23 and the first electric telescopic rod 232 will not affect the circumferential movement of the detection rod 242 to detect the material.

[0029] Furthermore, such as Figure 2 As shown, four mounting blocks 11 are fixedly installed on the outer surface of the material box 1. Several rollers 12 are rotatably installed in the inner cavity of the mounting block 11. A steel cable 13 is installed between two adjacent rollers 12 for transmission. A first motor 14 is fixedly installed on one side of the mounting block 11. The output shaft of the first motor 14 is fixedly connected to a connecting shaft 15. The connecting shaft 15 is fixedly connected to the rollers 12.

[0030] When in use, the material box 1 moves on the production line. The output shaft of the first motor 14 drives the connecting shaft 15 to rotate, and the connecting shaft 15 drives the two rollers 12 to rotate. The rollers 12 rub against the steel cable 13 to drive the material box 1.

[0031] Furthermore, such as Figure 5 and Figure 6 As shown, a second mounting bracket 3 is fixedly installed on one side of the material box 1. Both the second mounting bracket 3 and the inner cavity of the material box 1 are rotatably mounted with transmission rollers 31. The conveyor belt 35 is wound and installed on the outer surface of the two transmission rollers 31. A sixth motor 311 is fixedly installed on one side of the second mounting bracket 3, and the output shaft of the sixth motor 311 is fixedly connected to the transmission roller 31.

[0032] When the present invention is in use, after the material enters the inner cavity of the material box 1, it will fall to the top of the conveyor belt 35. In order to facilitate the transfer of the material at the top of the conveyor belt 35, the output shaft of the sixth motor 311 drives the transmission roller 31 to rotate, and the transmission roller 31 drives the conveyor belt 35 to rotate, thereby realizing the transfer of the material.

[0033] Furthermore, such as Figure 6 As shown, a first support plate 4 is fixedly installed in the inner cavity of the material box 1. The first support plate 4 and the second support plate 41 are located in the inner cavity and bottom of the conveyor belt 35, respectively. A plurality of second electric telescopic rods 42 are fixedly installed in the inner cavity of the material box 1. The plurality of second electric telescopic rods 42 are divided into two groups, and the output ends of the two groups of second electric telescopic rods 42 are fixedly connected to two bearing plates 43, respectively.

[0034] In use, the second electric telescopic rod 42 extends to move the support plate 43 upward, so that the top of the support plate 43 is at the same level as the top of the conveyor belt 35. This makes it easy for the lever 57 to move the material on the top of the conveyor belt 35 to the top of the support plate 43, and also makes it easy to move the material from the top of the support plate 43 to the top of the conveyor belt 35. In use, the first support plate 4 can support the conveyor belt 35 to prevent the material from bending due to the elasticity of the conveyor belt 35 after it is placed on top of the conveyor belt 35, which would prevent the material from sliding between the conveyor belt 35 and the support plate 43. The second support plate 41 can divide the inner cavity of the material box 1 into two parts, so that qualified materials and unqualified materials can be clearly separated.

[0035] Furthermore, such as Figure 7 As shown, the inner cavity of the material box 1 has two second grooves 5. The mounting plate 51 is slidably installed in the inner cavity of the second groove 5. A threaded rod 54 is rotatably installed in the inner cavity of the second groove 5. The threaded rod 54 is threadedly connected to the mounting plate 51. One end of the threaded rod 54 is fixedly connected to a fourth motor 55. The fourth motor 55 is fixedly installed on one side of the material box 1. The inner cavity of the second groove 5 has two third grooves 52, and the inner cavity of the third groove 52 is slidably installed with limit blocks 53. Both limit blocks 53 are fixedly connected to the mounting plate 51.

[0036] The mounting plate 51 is fixedly mounted on the guide rail at the bottom. A linear motor 58 is slidably mounted in the inner cavity of the guide rail. A fifth motor 56 is fixedly mounted on the bottom of the linear motor 58. The output shaft of the fifth motor 56 is fixedly connected to the lever 57.

[0037] In use, when it is necessary to move the material, the fourth motor 55 first drives the threaded rod 54 to rotate via its output shaft. This, in conjunction with the two limiting blocks 53, allows the rod to slide within the third groove 52, thus limiting the movement of the limiting blocks 53. The limiting blocks 53 can only slide along the inner cavity of the third groove 52. When the mounting plate 51 slides to the material side, the linear motor 58 slides along the guide rail, moving the lever 57 to the material side. The fifth motor 56 then drives the lever 57 to rotate via its output shaft, increasing the contact area between the lever 57 and the material. The linear motor 58 then drives the lever 57 to slide, thus moving the material. When the linear motor 58 moves the lever 57, the lever 57 is in a horizontal position, which prevents the material from affecting the sliding of the lever 57.

[0038] Working principle: The multi-axis robotic arm 2 moves the first mounting bracket 21 to the top of the material. The output shaft of the second motor 222 drives the bidirectional threaded rod 221 to rotate. This, combined with the sliding rod 22 limiting the first clamping plate 23, brings the two clamping plates 23 closer together to clamp the material. During the material transfer process, the output shaft of the third motor 244 drives the gear 243 to rotate. The gear 243 further drives the gear ring 241 to rotate within the limiting sleeve 24. As the gear ring 241 rotates, it also drives the detection rod 242 to rotate. At this point, the material is in... Within the rotation range of the detection rod 242, the detection rod 242 can be rotated in a circle by the toothed ring 241, enabling the detection rod 242 to inspect the entire exterior of the material. Then, the material is transferred to the top of the conveyor belt 35 by the multi-axis robotic arm 2. For qualified and unqualified materials, the lever 57 is used to move them to the top of the two bearing plates 43 respectively, thereby classifying the materials. Unqualified materials are collected and further processed, while qualified materials can be taken out from the inner cavity of the material box 1 by the multi-axis robotic arm 2 to enter the next process.

[0039] The extension of the output end of the second electric telescopic rod 42 allows the support plate 43 to move upwards, bringing the top of the support plate 43 to the same horizontal plane as the top of the conveyor belt 35. This facilitates the lever 57 to move material from the top of the conveyor belt 35 to the top of the support plate 43, and also facilitates the movement of material from the top of the support plate 43 to the top of the conveyor belt 35. During use, the first support plate 4 supports the conveyor belt 35, preventing material from bending due to the elasticity of the conveyor belt 35 after it is placed on top, thus preventing the material from sliding between the conveyor belt 35 and the support plate 43. The second support plate 41 divides the inner cavity of the material box 1 into two parts, allowing for clear separation of qualified material from... Defective materials are separated. The output shaft of the fourth motor 55 drives the threaded rod 54 to rotate, which, together with the two limit blocks 53, slides in the inner cavity of the third groove 52, thereby limiting the limit blocks 53. The limit blocks 53 can only slide along the inner cavity of the third groove 52. When the mounting plate 51 slides to the material side, the linear motor 58 slides along the guide rail, driving the lever 57 to the material side. The output shaft of the fifth motor 56 drives the lever 57 to rotate, increasing the contact area between the lever 57 and the material. The linear motor 58 then drives the lever 57 to slide, which can move the material. When the linear motor 58 moves the lever 57, the lever 57 is in a horizontal state, which can prevent the material from affecting the sliding of the lever 57.

[0040] Since the structure of the linear motor 58 is existing technology, it is not described in this invention document. The detection rod 242 is connected to a controller, which can control the start and stop of the fourth motor 55 and the linear motor 58 according to the detection results.
