Description

Technical Field

[0001] This invention relates to the field of automated storage and retrieval system conveyor technology, specifically a conveyor for testing injection molded finished products. Background Technology

[0002] Injection molding is a method of industrial product manufacturing, typically using rubber injection molding and plastic injection molding. Injection molding can also be divided into compression molding and die casting based on the molding method. An automated storage and retrieval system (AS / RS) is an automated warehousing system composed of high-rise automated racking, stacker cranes, various types of forklifts, inbound and outbound systems, automated guided vehicles (AGVs), control systems, and peripheral equipment.

[0003] When storing packaged injection-molded finished products in an automated storage and retrieval system, existing warehousing systems typically use conveyor equipment to store or retrieve products one by one, which is relatively inefficient. When inspecting injection-molded finished products, it is inconvenient to directly transport and inspect multiple stacked products via conveyor belts. Summary of the Invention

[0038] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0039] like Figure 1 , Figure 6 , Figure 8 , Figure 14 As shown, the present invention provides a conveyor for testing injection molded finished products, including a testing table 1, a conveying structure 2 on the side of the testing table 1, a transmission structure 3 at the end of the testing table 1, an automated three-dimensional warehouse structure 5 on one side of the conveying structure 2, a connecting structure 4 on the inner side of the conveying structure 2, a supporting structure 6 on the side of the conveying structure 2, and a blocking structure 7 on the side of the automated three-dimensional warehouse structure 5.

[0040] Specifically, such as Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8As shown, the transmission structure 2 includes a transmission frame 201. The side of the detection table 1 is provided with the transmission frame 201. A first pulley 203 is rotatably connected to each side of the transmission frame 201. A second pulley 205 is rotatably connected to each side of the top of the transmission frame 201. A lifting belt 204 is sleeved between the first pulley 203 and the second pulley 205. A plurality of bearing blocks 206 are fixedly connected to the side of the lifting belt 204 at equal intervals. A receiving groove 210 is opened on each side of the transmission frame 201. A top plate 202 is fixedly connected to the top side of the transmission frame 201. A limiting plate 207 is fixedly connected between the lifting belts 204 on both sides. A contact plate 209 is abutted on the top side of the limiting plate 207. A first spring 208 is fixedly connected between the contact plate 209 and the top plate 202.

[0041] When the lifting belt 204 rotates, the bearing blocks 206 on the side of the lifting belt 204 can support the packaged injection molded products. The lifting belt 204 is provided with multiple sets of bearing blocks 206, so that the transfer frame 201 can transport multiple injection molded products at the same time. On the other hand, when the lifting belt 204 rotates, the injection molded products can be released or lifted one by one, which facilitates the loading and unloading of products. A top plate 202 is provided at the top of the transfer frame 201. The rotation range of the lifting belt 204 can be limited by the contact between the limiting plate 207 provided between the two lifting belts 204 and the top plate 202. A contact plate 209 is provided on the bottom side of the top plate 202. The first spring 208 provided on the contact plate 209 can play a buffering role during the lifting process of the loaded injection molded products.

[0042] Specifically, such as Figure 1 , Figure 2 , Figure 3 As shown, the transmission structure 3 includes a first conveyor belt 301, which is installed in the middle of the detection platform 1. A second conveyor belt 302 is installed at the end of the first conveyor belt 301 on the detection platform 1. The width of the first conveyor belt 301 is greater than the width of the second conveyor belt 302. The second conveyor belt 302 is located in the middle of the detection platform 1. A first rotating shaft 303 is fixedly connected to the end of the first conveyor belt 301. A second rotating shaft 307 is fixedly connected to the end of the second conveyor belt 302 adjacent to the end of the first conveyor belt 301. A first gear 304 is fixedly connected to the end of the first rotating shaft 303. A second gear 306 is fixedly connected to the end of the second rotating shaft 307. A reversing gear 305 meshes between the first gear 304 and the second gear 306. The reversing gear 305 is rotatably connected to the detection platform 1.

[0043] When the transfer frame 201 is loaded with injection-molded products, it is moved to the end of the inspection table 1. At this time, the second conveyor belt 302 on the inspection table 1 is located on the middle platform of the transfer frame 201. After the first conveyor belt 301 rotates under the drive of the motor, the first rotating shaft 303 at its end will drive the second rotating shaft 307 and the second conveyor belt 302 connected to the second rotating shaft 307 to rotate in the same direction through the transmission effect of the first gear 304, the second gear 306 and the reversing gear 305. At this time, the products located between the two lifting belts 204 will be rotated in the same direction. As the injection-molded products gradually descend, since the width of the second conveyor belt 302 is smaller than that of the first conveyor belt 301, the lifting belt 204 and the side-mounted support block 206 will turn to the other side through the receiving groove 210. At the same time, the injection-molded products currently placed on the support block 206 are placed on the surface of the second conveyor belt 302. As the second conveyor belt 302 rotates, the injection-molded products will continue to be transported to the first conveyor belt 301. Finally, the injection-molded products are transported to the inside of the testing equipment for testing. In this way, the stacked injection-molded products can be quickly unloaded and tested.

[0044] Specifically, such as Figure 1 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 As shown, the automated storage and retrieval system (AS / RS) structure 5 includes a storage rack 501. A storage rack 501 is located on one side of the transmission rack 201. Multiple third conveyor belts 502 are installed parallel to each other on the inner side of the storage rack 501. A lifting frame 506 is slidably connected to each side of the third conveyor belt 502. Multiple sliding sleeves 507 are rotatably connected to the side of the lifting frame 506. A lifting groove 508 is formed on the inner side of the lifting frame 506. A drive rod 509 is slidably connected to the lifting frame 506 through the lifting groove 508. The end of the drive rod 509 is slidably connected to the storage rack 501. A traction device is slidably connected to the end of the storage rack 501. A guide plate 505 is provided, and the side of the guide plate 505 is fixedly connected to the ends of multiple drive rods 509. A drive motor 503 is installed at the end of the storage rack 501. A drive screw 504 is fixedly connected to the output end of the drive motor 503. The end of the drive screw 504 is rotatably connected to the storage rack 501. The drive screw 504 is threadedly connected to the middle of the guide plate 505. Multiple buffer plates 510 are slidably connected to the inner side of the storage rack 501. The buffer plates 510 are respectively provided at the ends of the corresponding third conveyor belts 502. A third spring 511 is fixedly connected between the side of the buffer plate 510 and the storage rack 501.

[0045] The storage rack 501 for storing injection-molded products has a multi-layer structure. Each layer is equipped with a third conveyor belt 502 driven by a motor. The length of the third conveyor belt 502 is greater than the length of the storage rack 501. When the transfer rack 201 moves to the end of the storage rack 501, the extended portion of the third conveyor belt 502 moves to the inside of the storage rack 501. The width of the third conveyor belt 502 is smaller than the width of the injection-molded product packaging. During product storage, after the product is loaded by the lifting belt 204 on the transfer rack 201, the transfer rack 201 is moved to the end of the storage rack 501. To ensure the third conveyor belt 502 is positioned at the bottom of the corresponding injection-molded product, after the transfer frame 201 is in place, the product is transferred to the third conveyor belt 502 by rotating the lifting belt 204. Starting the third conveyor belt 502 moves the product towards the inside of the storage rack 501. Lifting frames 506 are located on both sides of the third conveyor belt 502. When the product moves to the sliding sleeve 507 on the side of the lifting frame 506, the height of the sliding sleeve 507 is slightly higher than the surface of the third conveyor belt 502, causing part of the product to move to the top of the sliding sleeve 507. As subsequent products are stored, [the product will move further down the sliding sleeve]. The previously stored products are pushed inwards towards the storage rack 501. The sliding sleeve 507 prevents continuous friction between the products and the third conveyor belt 502 during storage. A buffer plate 510 is located at the other end of the storage rack 501 on the third conveyor belt 502 to block and cushion the inserted products, reducing damage from collisions. Similarly, when removing products, the transfer rack 201 is moved to the end of the storage rack 501, and the limiting plate 207 on the lifting belt 204 is moved to the top. Since the products are supported by the sliding sleeve 507, it is necessary to start... The drive motor 503 drives the traction plate 505 to slide through the rotation of the drive screw 504. The traction plate 505 then pulls the drive rods 509 on the bottom side of all the lifting frames 506. Through the setting of the lifting groove 508, the lifting frame 506 will eventually lower its height, so that the product falls back to the surface of the third conveyor belt 502. At this time, multiple injection molded products can be stacked and transported to the inside of the transfer frame 201 by the rotation of the third conveyor belt 502 of each layer. Then, by slightly rotating the lifting belt 204 to the top, the selected product can be taken out from the storage rack 501 and transferred, improving storage and retrieval efficiency.

[0046] Specifically, such as Figure 1 , Figure 3 , Figure 6 , Figure 7 , Figure 8 , Figure 13As shown, the connecting structure 4 includes a connecting plate 403. The connecting plate 403 is slidably connected to the inner side of the transmission frame 201. A slot 405 is opened at each end of the connecting plate 403. A first locking tooth 402 is fixedly connected to the end of the detection table 1 corresponding to the end of the connecting plate 403. A second locking tooth 406 is fixedly connected to the side of the storage rack 501 corresponding to the other end of the connecting plate 403. A release rod 401 is rotatably connected to the middle of the transmission frame 201. The release rod 401 and the connecting plate 403 are perpendicular to each other. A protruding structure is provided in the middle of the release rod 401. The release rod 401 abuts against the top side of the connecting plate 403 through the protruding structure in the middle. A second spring 404 is fixedly connected between the connecting plate 403 and the transmission frame 201.

[0047] To facilitate the connection and fixation between the transfer frame 201, the testing table 1, and the storage rack 501, a connecting plate 403 is provided on the inner side of the transfer frame 201. When the side of the transfer frame 201 abuts against the testing table 1 or the storage rack 501, the first locking tooth 402 and the second locking tooth 406 provided on the side of the testing table 1 and the storage rack 501 can engage with the connecting plate 403 through the slot 405, thereby ensuring the stability of the transfer frame 201 during product transfer. When the transport is completed, the user can rotate the release rod 401, and the protrusion provided on the side of the release rod 401 will press the connecting plate 403 downwards to release the engagement state of the slot 405, making it convenient to use.

[0048] Specifically, such as Figure 6 , Figure 8 As shown, the support structure 6 includes a support frame 601. Two support frames 601 are slidably connected to the inner side of the transmission frame 201. A fourth spring 602 is fixedly connected between the support frame 601 and the transmission frame 201. A cam 603 abuts between the two support frames 601. A shaft 604 is fixedly connected to the middle of the cam 603. The shaft 604 is rotatably connected to the storage rack 501. A third gear 605 is fixedly connected to each end of the shaft 604. A rack 606 meshes with the side of the third gear 605. The rack 606 is slidably connected to the inner side of the transmission frame 201. One end of the rack 606 abuts against the detection table 1.

[0049] When products are transported via the transfer frame 201, a support frame 601 is provided at the receiving groove 210 of the transfer frame 201 to improve stability. When the transfer frame 201 is in transport mode, the end of the support frame 601 will block the receiving groove 210. At this time, the bearing block 206 on the lifting belt 204 will abut against the end of the support frame 601 when it descends, thus ensuring stability during movement and keeping the product at the bottom at a certain height, thereby ensuring the connection between the transfer frame 201 and the inspection table 1 or the storage rack 501. When the transfer frame 201 is connected to the inspection table 1 or the storage rack 501, the extended part of the rack 606 on the corresponding side will be pushed to the other side. At this time, the rack 606 drives the third gear 605 to rotate, which in turn drives the cam 603 to rotate through the shaft 604. The cam 603 pushes the two support frames 601 on both sides to the sides, thereby pushing the end of the support frame 601 away from the receiving groove 210. At this time, the lifting belt 204 can rotate freely to pick up and put down products.

[0050] Specifically, such as Figure 9 , Figure 12 , Figure 13 , Figure 14 , Figure 15 As shown, the blocking structure 7 includes a limiting rotating rod 701. Multiple limiting rotating rods 701 are rotatably connected to the side of the storage rack 501. A lifting column 703 is vertically slidably connected to the inner side of the storage rack 501. A fifth spring 704 is fixedly connected between the top of the lifting column 703 and the storage rack 501. Multiple horizontal grooves 705 are opened on the side of the lifting column 703. The end of the limiting rotating rod 701 is slidably connected to the lifting column 703 through the horizontal grooves 705. An inclined groove 706 is opened at the bottom of the lifting column 703. A pushing block 702 is slidably connected to the side of the storage rack 501. The pushing block 702 is slidably connected to the lifting column 703 through the inclined groove 706.

[0051] Since the product is supported inside the storage rack 501 by the sliding sleeve 507, in order to prevent the product from sliding off, a limiting screw rod 701 is provided on the side of the storage rack 501 to block the stored injection molded product and prevent it from falling off. When the transfer rack 201 is connected to the storage rack 501, the side of the transfer rack 201 will push the bottom push block 702. The push block 702 will push the lifting column 703 to the top through the inclined groove 706. At this time, the end of the limiting screw rod 701 will slide in the corresponding transverse groove 705 on the side of the lifting column 703, thereby causing the limiting screw rod 701 to rotate to one side and release the blocking state of the stored injection molded product.

[0052] In use, the present invention firstly has casters installed on the bottom side of the conveyor frame 201 for transporting injection molded products, facilitating movement. A first pulley 203 driven by a motor is provided on each side of the conveyor frame 201. A lifting belt 204 is sleeved between the first pulley 203 and the second pulley 205 on the same side. When the lifting belt 204 rotates, the bearing blocks 206 on the side of the lifting belt 204 can support the packaged injection molded products. Multiple sets of bearing blocks 206 are provided on the lifting belt 204, allowing the conveyor frame 201 to transport multiple injection molded products simultaneously. Furthermore, when the lifting belt 204 rotates, the injection molded products can be released or lifted one by one, facilitating loading and unloading. A top plate 202 is located at the top of the conveyor frame 201, which is supported by lifting plates on both sides. The limiting plate 207 between the belts 204 and the top plate 202 restricts the rotation range of the lifting belt 204. The bottom side of the top plate 202 has an abutment plate 209. A first spring 208 on the abutment plate 209 provides a buffering effect during the lifting of the loaded injection-molded product. An injection-molded product testing device is installed on the testing platform 1. Through the conveying effect of the first conveyor belt 301, the injection-molded products placed on the first conveyor belt 301 can be conveyed and tested. When the transfer frame 201 is loaded with injection-molded products, it is moved to the end of the testing platform 1. At this time, the second conveyor belt 302 on the testing platform 1 is located on the middle platform of the transfer frame 201. After the first conveyor belt 301 rotates under the drive of the motor... The first rotating shaft 303 at its end drives the second rotating shaft 307 and the second conveyor belt 302 connected to the second rotating shaft 307 to rotate in the same direction through the transmission effect of the first gear 304, the second gear 306, and the reversing gear 305. At this time, the injection molded product located between the two lifting belts 204 is gradually lowered. Since the width of the second conveyor belt 302 is smaller than that of the first conveyor belt 301, the lifting belt 204 and the side support block 206 will turn to the other side through the receiving groove 210. At the same time, the injection molded product currently placed on the support block 206 is placed on the surface of the second conveyor belt 302. As the second conveyor belt 302 rotates, it will continue to transport the injection molded product to the first conveyor belt 301, and finally transport the injection molded product into the testing equipment. The stacked injection-molded products are inspected from the side, allowing for rapid unloading and inspection. The storage rack 501 for storing the injection-molded products has a multi-layer structure, with each layer equipped with a third conveyor belt 502 driven by a motor. The length of the third conveyor belt 502 is greater than the length of the storage rack 501. When the transfer rack 201 moves to the end of the storage rack 501, the extended portion of the third conveyor belt 502 moves to the inside of the storage rack 501. The width of the third conveyor belt 502 is smaller than the injection-molded product packaging. During product storage, after the product is loaded via the lifting belt 204 on the transfer rack 201, the transfer rack 201 is moved to the end of the storage rack 501, ensuring that the third conveyor belt 502 is located at the bottom side of the corresponding injection-molded product.After the transfer rack 201 is in place, the product is transferred to the third conveyor belt 502 by the rotation of the lifting belt 204. Activating the third conveyor belt 502 moves the product towards the inside of the storage rack 501. Lifting frames 506 are located on both sides of the third conveyor belt 502. When the product moves to the sliding sleeve 507 on the side of the lifting frame 506, the height of the sliding sleeve 507 is slightly higher than the surface of the third conveyor belt 502, causing part of the product to move to the top of the sliding sleeve 507. As subsequent products are stored, the previously stored products are pushed towards the inside of the storage rack 501. The sliding sleeve 507 prevents continuous friction between the product and the third conveyor belt 502 during storage. The storage rack 501 is located in the... The other end of the third conveyor belt 502 is equipped with a buffer plate 510, which can block and buffer the inserted products to reduce damage caused by collision. When removing the products, the same method is used: the transfer frame 201 is moved to the end of the storage rack 501, and the limiting plate 207 on the lifting belt 204 is moved to the top. At this time, since the products are supported by the sliding sleeve 507, the drive motor 503 needs to be started. The rotation of the drive screw 504 drives the traction plate 505 to slide. The traction plate 505 will then pull the drive rods 509 on the bottom side of all the lifting frames 506. Through the setting of the lifting groove 508, the lifting frame 506 will eventually be lowered, so that the products fall back to the surface of the third conveyor belt 502. At this time, the products can be transported through each layer of the third conveyor belt. The rotation of the conveyor belt 502 simultaneously transports multiple injection-molded products stacked to the inside of the transfer rack 201. Then, slightly rotating the lifting belt 204 upwards allows the selected product to be retrieved from the storage rack 501 for transfer, improving storage and retrieval efficiency. To facilitate the connection and fixation between the transfer rack 201, the inspection table 1, and the storage rack 501, a connecting plate 403 is provided on the inner side of the transfer rack 201. When the side of the transfer rack 201 abuts against the inspection table 1 or the storage rack 501, the first locking teeth 402 and the second locking teeth 406 on the sides of the inspection table 1 and the storage rack 501 can engage with the connecting plate 403 through the locking groove 405, thereby ensuring the stability of the transfer rack 201 during product transfer. Upon completion of transport, the user can... Rotating the release lever 401 causes the protruding structure on the side of the release lever 401 to press the connecting plate 403 downwards, thus releasing the locking state of the slot 405 for easy use. When the product is transported via the transfer frame 201, a support frame 601 is provided at the receiving slot 210 of the transfer frame 201 to improve stability. When the transfer frame 201 is in transport mode, the end of the support frame 601 blocks the receiving slot 210. At this time, the bearing block 206 on the lifting belt 204 will abut against the end of the support frame 601 when descending, thus ensuring stability during movement and maintaining the product at the bottom at a certain height, thereby ensuring the connection between the transfer frame 201 and the inspection table 1 or storage rack 501.When the transfer frame 201 is connected to the testing table 1 or the storage rack 501, the extended portion of the rack 606 on the corresponding side is pushed to the other side. At this time, the rack 606 drives the third gear 605 to rotate, which in turn drives the cam 603 to rotate through the shaft 604. The cam 603 pushes the two support frames 601 on both sides to the sides, thereby pushing the ends of the support frames 601 away from the receiving groove 210. At this time, the lifting belt 204 can rotate freely to pick up and put down the product. Since the product is supported inside the storage rack 501 by the sliding sleeve 507, it provides... To prevent products from sliding out, a limiting screw rod 701 is installed on the side of the storage rack 501 to block the stored injection-molded products and prevent them from falling out. When the transfer rack 201 is connected to the storage rack 501, the side of the transfer rack 201 pushes the bottom pushing block 702. The pushing block 702 pushes the lifting column 703 upward through the inclined groove 706. At this time, the end of the limiting screw rod 701 slides in the corresponding transverse groove 705 on the side of the lifting column 703, causing the limiting screw rod 701 to rotate to one side, releasing the obstruction of the stored injection-molded products.
