Description

Technical Field

[0001] This utility model relates to the field of hot melt equipment technology, and specifically to a hot melt equipment. Background Technology

[0002] During the production of plastic products, hot-melt processing is generally required. Many plastic products often have several weld points. In the past, welding was mostly done manually, requiring workers to manually weld the components before applying the hot-melt weld. Only one point could be welded at a time, which was tedious, inefficient, labor-intensive, and prone to problems like incomplete welds. Later, manufacturers adopted hot-melt equipment for processing plastic products. This equipment is mainly used to achieve connections or seals by heating and melting materials, and it has gradually become widely used in plastic welding, hot-melt adhesive spraying, and other fields.

[0003] Currently available hot melt equipment can perform hot melt processing on plastic products. For example, Chinese invention patent application CN112700588A discloses an automatic hot melt equipment, which includes: a work frame, a temperature controller, a cylinder, a fixed plate, a hot melt head, and a template. The work frame is a double-layer structure including a top plate and a bottom plate, with a guide rail between the top plate and the bottom plate. The fixed plate is installed on the guide rail. The cylinder body is installed on the lower surface of the top plate, and the piston rod of the cylinder is connected to the fixed plate, driving the fixed plate to slide along the guide rail. The hot melt head is installed on the fixed plate, with its heating end extending downward through the fixed plate. The tail of the hot melt head is connected to the temperature controller. The template is set on the upper surface of the bottom plate, and a fixing groove is provided on the top surface of the template.

[0004] However, this existing automatic hot melt equipment uses a cylinder to push a fixed plate downward along a guide rail. After the hot melt head contacts the weld point, it begins to heat and pressurize to weld the weld point. However, this technical solution can only weld the product and cannot inspect the product after hot melt. Furthermore, the degree of automation is not high, and it cannot protect the product after hot melt by coating, which can easily affect the product processing quality. In addition, this technical solution uses the traditional hot air hot melt method, which has slow heat dissipation and is not suitable for mass production.

[0005] In view of the above, the inventors propose the following technical solution. Summary of the Invention

[0028] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0029] See Figures 1 to 10 The image shows a hot-melt equipment, comprising: a hot-melt mechanism 1 for hot-melt processing of products; a conveyor line 2 for moving a blister pack 10; a feeding mechanism 3 disposed on one side of the conveyor line 2 for feeding products to the hot-melt mechanism 1; a six-axis robot 5 disposed beside the conveyor line 2 for gripping and moving products for processing; an inspection mechanism 6 disposed beside the six-axis robot 5 for inspecting the hot-melt products; and a stacking and film-tearing mechanism 7 disposed on the conveyor line 2 for applying film to the blister pack 10 and for stacking and lifting it. After the hot-melt mechanism 1 completes the hot-melt processing of the product, the six-axis robot 5 grips the product and moves it to the inspection mechanism 6 for inspection.

[0030] In this invention, a six-axis robotic arm 5 picks up the product inspected by the feeding mechanism 3 and places it into the hot-melt mechanism 1 for hot-melt processing. After processing, the inspection mechanism 6 performs a quality inspection on the product. Simultaneously, the transmission line 2 moves the blister tray 10 to the stacking and tearing film mechanism 7, where the six-axis robotic arm 5 continues to pick up the processed product and place it into the stacking and tearing film mechanism 7 for film coating. This allows for quality inspection and film protection after hot-melt processing, significantly improving processing quality. Furthermore, the stacking and tearing film mechanism 7 drives the blister tray 10 to lift and stack, effectively improving processing efficiency. In addition, compared with existing structures, this invention changes the traditional cylinder-driven method to an electric cylinder-driven method, greatly improving processing accuracy. It also changes the traditional hot air hot-melt method to a pulse hot-melt method, where the welding head heats up rapidly, causing the hot-melt column to soften. This results in fast heating, high processing accuracy, and easy heat dissipation.

[0031] Since a protective film needs to be covered on the product surface after the hot melt processing is completed, this utility model uses a stacking and tearing film mechanism 7 to coat and lift the product, which can complete the coating while improving production efficiency and greatly improving product quality. Specifically, the stacking and tearing film mechanism 7 includes a stacking housing 71, a lifting device 72 that is vertically movable and installed inside the stacking housing 71 to drive the blister trays 10 to be lifted and stacked, a protective film holder 73 installed on the stacking housing 71 for placing the protective film, a film clamping roller 74 installed on the stacking housing 71 for clamping the protective film for movement, a film coating linear module 78 horizontally installed on the stacking housing 71, a film coating clamping arm 75 that is slidably installed on the film coating linear module 78 for driving the protective film to move and cover the blister trays 10, a fusing clamping arm 76 installed between the film clamping roller 74 and the film coating clamping arm 75 for fusing the protective film, and a blister tray handling robot 77 installed on the stacking housing 71 for transferring the blister trays 10 on the transmission line 2 to the lifting device 72 for stacking. Here, the roll of protective film is placed on the protective film holder 73. The first section of protective film is pulled through the clamping roller 74 and the fusion clamping arm 76 and then pulled onto the covering clamping arm 75. During the covering process, the covering clamping arm 75 moves linearly through the covering linear module 78 to pull the protective film and cover the blister tray 10 after the product is loaded. After the covering is completed, the lifting device 72 lowers the blister tray 10. At the same time, the covering clamping arm 75 slides back to the side of the fusion clamping arm 76 along the covering linear module 78. Then, the blister tray handling robot 77 moves the blister tray 10 above the transmission line 2 and stacks it on top of the previous blister tray 10 to increase storage capacity. After the blister tray 10 is loaded with products, the above actions are repeated.

[0032] The lifting device 72 includes a lifting slide rail 721 arranged vertically in the stacking housing 71, a lifting slider 722 slidably arranged on the lifting slide rail 721, a lifting frame 723 fixed on the lifting slider 722 and capable of being raised and lowered accordingly, a lifting linear module 724 arranged in the stacking housing 71 and capable of being driven to lift the lifting frame 723 to drive the lifting frame 723 to be raised and lowered, and a lifting conveyor belt 725 arranged on the lifting frame 723 for placing the blister tray 10. Here, the lifting linear module 724 drives the lifting frame 723 to rise and fall along the lifting slide rail 721, so that multiple blister trays 10 can be stacked at one time, thereby enhancing processing efficiency and saving space. Preferably, five blister trays 10 loaded with products can be stacked at one time. When the number of stacks reaches five, the lifting linear module 724 drives the lifting frame 723 to rise along the lifting slide rail 721. After rising to be flush with the transmission line 2, the five stacked blister trays 10 are transferred to the transmission line 2 by the lifting conveyor belt 725, and are driven by the transmission line 2 to flow.

[0033] The hot-melting mechanism 1 includes a hot-melting worktable 11, a hot-melting positioning fixture 12 disposed on the hot-melting worktable 11 for positioning the product, a lifting guide column 13 vertically disposed on the hot-melting worktable 11, a top plate 14 mounted on the upper end of the lifting guide column 13, a hot-melting lifting plate 15 disposed on the lifting guide column 13 and located above the hot-melting positioning fixture 12 in a liftable manner, a hot-melting electric cylinder 16 disposed on the top plate 14 and tractably connected to the hot-melting lifting plate 15, a hot-riveting assembly 17 disposed on the hot-melting lifting plate 15 for hot-melting processing of the product, and a hot-melting outer cover 18 disposed on the hot-melting worktable 11 for enhanced protection. Here, the hot-melting mechanism 1 of this utility model changes the traditional cylinder-driven method to an electric cylinder-driven method, significantly improving processing accuracy. It also changes the traditional hot air hot-melting method to a pulse hot-melting method, rapidly heating the hot-melting column to soften it through the rapid heating of the welding head, resulting in fast heating speed, high processing accuracy, and easy heat dissipation.

[0034] The testing mechanism 6 includes a testing bracket 61 mounted on the hot melt cover 18, a testing lens 62 mounted on the testing bracket 61, a light source plate 63 mounted on the testing bracket 61 for supplementing light to the testing lens 62, and a barcode scanner 64 mounted on one end of the testing bracket 61 for scanning and identifying the product.

[0035] The feeding mechanism 3 includes a feeding workbench 31, a feeding linear module 32 mounted on the feeding workbench 31 for moving the product, a linear pallet 33 mounted on the feeding linear module 32 for placing the product, a bracket 34 mounted on the feeding workbench 31, a feeding detection device 35 mounted on the bracket 34 for detecting and positioning the linear pallet 33, and a feeding outer cover 36 mounted on the feeding workbench 31 for enhanced protection.

[0036] The six-axis robotic arm 5 includes a drive base 51, a first rotating arm 52 rotatably mounted on the drive base 51, a second transmission arm 53 pivotally mounted on the first rotating arm 52, a third rotating arm 54 rotatably connected to the end of the second transmission arm 53, a fourth transmission arm 55 pivotally mounted on the third rotating arm 54, a fifth rotating arm 56 rotatably connected to the fourth transmission arm 55, and a sixth gripping arm 57 mounted on the fifth rotating arm 56 for gripping and moving a product. Preferably, the first rotating arm 52, the fifth rotating arm 56, and the third rotating arm 54 are capable of rotating 360°, and the second transmission arm 53 and the fourth transmission arm 55 are capable of pivoting at least 180°, providing a wide range of coverage and ensuring precise gripping and movement of the product.

[0037] The transmission line 2 includes a first transmission section 21 disposed on one side of the stacking and tearing film mechanism 7 for transmitting the blister pack 10, a second transmission section 22 disposed on the other side of the stacking and tearing film mechanism 7 for transmitting the stacked blister pack 10, and a transmission detection device 23 disposed on the first transmission section 21 for detecting whether the blister pack 10 is in position. Here, the transmission detection device 23 is disposed on the first transmission section 21 and close to the stacking and tearing film mechanism 7. When a blister pack 10 reaches below the transmission detection device 23, it will be picked up by the blister pack handling robot 77.

[0038] The six-axis robot arm 5 is provided with a flipping mechanism 500 for angle detection of the product; the hot melt mechanism 1 is provided with a light strip testing mechanism 4 for light strip testing of the product; and the blister tray 10 is provided with six placement positions 520 for placing the product.

[0039] The six-axis robot arm 5 is provided with a support base 50 for support, and the flipping mechanism 500 is disposed on the support base 50. The flipping mechanism 500 includes a flipping bracket 511 disposed on the support base 50, a first flipping fixture 512 and a second flipping fixture 513 disposed on the flipping bracket 511 for positioning the product, a first photoelectric switch 514 disposed next to the first flipping fixture 512, and a second photoelectric switch 515 disposed next to the first flipping fixture 512 for detecting the product angle by interacting with the first photoelectric switch 514. Here, by sensing the interaction between the first photoelectric switch 514 and the second photoelectric switch 515, it is possible to detect whether the product is at the correct angle, so that the six-axis robot arm 5 can handle it.

[0040] Preferably, a protective fence 210 is provided around the transmission line 2 to enhance protection and prevent accidental injury to operators.

[0041] In summary, in this invention, a six-axis robotic arm 5 picks up the product inspected by the feeding mechanism 3 and places it into the hot-melt mechanism 1 for hot-melt processing. After processing, the inspection mechanism 6 performs a quality inspection on the product. Simultaneously, the transmission line 2 moves the blister tray 10 to the stacking and tearing film mechanism 7, where the six-axis robotic arm 5 continues to pick up the processed product and place it into the stacking and tearing film mechanism 7 for film coating. This allows for quality inspection and film protection after hot-melt processing, significantly improving processing quality. Furthermore, the stacking and tearing film mechanism 7 drives the blister tray 10 to lift and stack, effectively improving processing efficiency. In addition, compared with existing structures, this invention changes the traditional cylinder-driven method to an electric cylinder-driven method, significantly improving processing accuracy. It also changes the traditional hot air hot-melt method to a pulse hot-melt method, where the welding head rapidly heats up, causing the hot-melt column to soften. This results in fast heating, high processing accuracy, and easy heat dissipation.
