Description

Technical Field

[0001] The invention relates to the technical field of mechanical equipment, in particular to a laminating machine used in shoe production. Background Art

[0002] It is known that some composite products need to be connected by glue. For example, when making shoes, the upper and the sole generally need to be glued together, as well as the midsole and the outsole, so the sole needs to be glued. Common sole gluing is mainly done by manual brushing, which has low gluing efficiency and unstable gluing quality. In addition, liquid glue is used. Most liquid glues are solvent glues with formaldehyde added. Formaldehyde has an impact on human health, which limits production. At the same time, liquid glues are double-sided glues, which need to be applied on both sides of the two objects to be bonded. The amount of glue used is large, which increases the cost of double-sided gluing for enterprises. With the development of science and technology, hot melt adhesive (solid glue) as an emerging and environmentally friendly colloid has better overcome the defects of liquid glue, so it has been widely used. When using hot melt adhesive, it needs to be heated first to melt it from a solid state into a liquid before it can be applied on the surface of the product. Therefore, it works at a certain temperature and there is a risk of burns when applying it manually. Then, gluing devices using hot melt adhesive have appeared, but after gluing, the two substrates to be bonded still need to be manually bonded together, resulting in low work efficiency, unstable alignment, and poor consistency.

[0035] The first activation device 5 is assembled on the frame 1, and is used to dry the first substrate and the second substrate, remove the corresponding liquids of the first substrate and the second substrate, and achieve the preheating effect on the substrate, which is beneficial to the subsequent bonding production. The gluing device 6 is assembled on the frame 1 and is located downstream of the first activation device 5. The gluing device 6 is used to apply glue to the first substrate. The gluing device 6 is a gluing device for hot melt adhesive. The gluing device 6 has a glue groove 61 and a glue roller 62. The glue roller 62 is partially immersed in the glue groove 61, and the glue groove 61 and the glue roller 62 are driven up and down by the lifting and adjustable mechanism 63.

The lifting and adjustable mechanism 63 can adjust the contact relationship between the glue roller 62 and the first substrate to ensure stable and uniform gluing quality. In this embodiment, there are two glue devices 6, arranged front and back, which can achieve two gluing. Of course, one of them can be selected as needed. In this embodiment, in order to cooperate with gluing, limit rollers 113 are also provided on both sides of the area of ​​the first assembly line 11 located at the gluing station. The limit rollers 113 are used to cooperate with the left and right sides of the first supporting plate 111 to ensure that the first supporting plate 111 stably carries the first substrate through the glue device 6 to ensure the gluing quality. The second activation device 7 is assembled on the frame 1 and is located downstream of the glue device 6.

The first activation channels 51 and the second activation channels 71 are in the form of tunnels, and the first assembly line 11 and the second assembly line 12 respectively pass through different first activation channels 51 and second activation channels 71 in sequence. In this embodiment, it can be designed that the two first activation channels 51 are independently controlled, and the two second activation channels 71 are also independently controlled, so that they can be selectively used, convenient to control and energy-saving. The specific activation process is a prior art, and the working principle and other internal structures are not repeated here.

[0036] The alignment and laminating device 8 is assembled on the frame 1 and is located downstream of the second activation device 7. The alignment and laminating device 8 is used to adjust the spatial position of the first substrate and the second substrate and to laminate the second substrate on the upper adhesive surface of the first substrate to achieve automatic alignment and laminating production. The unloading mechanism 9 is assembled on the frame 1 and is used to transfer the laminated first substrate and the second substrate to a laminating device (shown in the figure), further pressurize and maintain the pressure, so that the first substrate and the second substrate are firmly adhered together. In this embodiment, the unloading mechanism 9 is in the form of a manipulator with a simple structure, convenient for manufacture, assembly and control, and preferably adopts negative pressure adsorption to grasp and move the material to achieve automatic unloading.

[0037] See also Figure 1 , 3 As shown in Figure 5, in this embodiment, the alignment and bonding device 8 includes a first alignment component 81 arranged in a matching manner with the first assembly line 11, a second alignment component 82 arranged in a matching manner with the second assembly line 12, a bonding robot 83 arranged across the first assembly line 11 and the second assembly line 12, and a flipping component 84 arranged in a matching manner with the second assembly line 12; the first alignment component 81 is used to adjust the spatial position of the first substrate on the first supporting plate 111; the flipping component 84 is used to flip the second substrate on the second supporting plate 121, so that the upper and lower surfaces and the front and rear sides of the second substrate are swapped, that is, the second substrate is flipped 180 degrees, so that the adhesive surface of the second substrate faces downward, and the direction is changed by swapping the front and rear sides of the second substrate to match the subsequent bonding. The second alignment component 82 is used to adjust the flipped second substrate so that the second substrate is parked at the spatial position set on the second supporting plate 121; the bonding robot 83 moves the second substrate and bonds it to the upper adhesive surface of the first substrate when the spatial positions of the first substrate and the second substrate are adjusted, so that the second substrate and the first substrate are aligned and bonded together.

[0038] In this embodiment, the first alignment component 81 drives the alignment adjustment of the first substrate by squeezing. The first alignment component 81 has a first alignment block 811, a second alignment block 812, a third alignment block 813 and a fourth alignment block 814 arranged around the first supporting plate 111. The first alignment block 811 and the fourth alignment block 814 form a front-to-back relationship, and the first alignment block 811 and the fourth alignment block 814 can both be raised and lowered, and at least one of the first alignment block 811 and the fourth alignment block 814 can move forward and backward. In the figure, the first alignment block 811 is driven by a series cylinder system to achieve up and down and forward and backward movement, wherein the upward movement of the first alignment block 811 is to lift up in order to provide a space for escape, so as to facilitate the first support plate 111 to carry the first substrate to move, and the downward movement of the first alignment block 811 is used for adjustment, and in conjunction with the forward and backward movement, to achieve the alignment of the first substrate and the backward movement of the first alignment block 814; the fourth alignment block 814 is driven up and down by a cylinder, and similarly, the upward movement of the fourth alignment block 814 is to lift up in order to provide a space for escape, and the downward movement of the fourth alignment block 814 is used to intercept and stop the front end of the first substrate to provide an alignment reference. The second alignment block 812 and the third alignment block 813 form a left-right relationship, and at least one of the second alignment block 812 and the third alignment block 813 can move left-right. As shown in the figure, the second alignment block 812 and the third alignment block 813 are driven by cylinders to move left and right, and by pushing the left and right sides of the first substrate, cooperating with the front and rear alignment adjustment of the first alignment block 811 and the fourth alignment block 814, the spatial position of the first substrate is adjusted to facilitate subsequent automatic bonding, which is accurate and stable.

[0039] In this embodiment, since the second substrate is first activated before bonding, the bonding surface of the second substrate is facing upward when the material is initially loaded. Therefore, in order to facilitate subsequent bonding, the second substrate needs to be flipped, that is, the second substrate is flipped 180 degrees by the flipping component 84 so that the adhesive surface of the second substrate faces downward. In this embodiment, the flipping component 84 includes a flipping shaft 841 spanning the upper side of the second assembly line 12 and a clamping claw 842 following the flipping shaft 841. The clamping claw 842 grabs the second substrate by left and right clamping, and then the flipping shaft 841 is driven to rotate by a motor or other mechanism, and the clamping claw 842 clamps the second substrate and follows the flipping. At the same time, the second supporting plate 121 continues to move forward from the lower side of the flipping shaft 841. After the second substrate is flipped, it happens to be located above the second supporting plate 121. At this time, the clamping claw 842 is released, and the second substrate falls on the second supporting plate 121 to achieve the flipping work. Subsequently, the second supporting plate 121 carries the flipped second substrate to the alignment adjustment station, and enters the second alignment component 82 to adjust the spatial position of the second substrate for subsequent bonding needs.

[0040] In this embodiment, the second alignment component 82 drives the alignment adjustment of the second substrate by squeezing. The second alignment component 82 has a first stop plate 821, a second stop plate 822 and a fifth alignment block 823 arranged around the second support plate 121. The first stop plate 821 is arranged at the front side of the moving direction of the second support plate 121, and a gap is left between the lower side of the first stop plate 821 and the upper side of the second support plate 121 so that the second support plate 121 can pass through, but at the same time, the second substrate can be stopped to provide a reference alignment. The second stop plate 822 and the fifth alignment block 823 are relatively arranged on the left and right sides of the moving direction of the second support plate 121, and the fifth alignment block 823 can move left and right through the cylinder drive, so that the fifth alignment block 823 is close to or away from the second stop plate 822. When the second substrate moves following the second support plate 121, the front end of the second substrate is stopped by the first stop plate 821, and the fifth alignment block 823 pushes the second substrate toward the second stop plate 822 from one side, thereby achieving the spatial position adjustment of the second substrate, which can facilitate the accurate grasping of the bonding manipulator 83 for bonding connection with the first substrate. The bonding manipulator 83 has a sliding seat 831, a bonding cylinder 832 and a material taking head 833. The sliding seat 831 is assembled on the gantry preset on the frame 1 through a linear slide structure and driven to slide back and forth between the first assembly line 11 and the second assembly line 12. The bonding cylinder 832 is installed on the sliding seat 831, and the bonding cylinder 832 is used to drive the material taking head 833 to move up and down to achieve material taking and bonding downward pressing. Preferably, in the figure, the material taking head 833 obtains the second substrate through negative pressure adsorption, and then moves with the sliding seat 831 to move the second substrate from the second assembly line 12 to the first assembly line 11, and is driven by the bonding cylinder 832 to bond the second substrate to the adhesive coating surface of the first substrate under a certain pressure, so as to achieve automatic alignment and bonding production. Finally, the bonded first and second substrates are output from the first assembly line 11. In this embodiment, the first and second substrates bonded together are further transferred to the laminating device through the unloading mechanism 9, and further pressurized and maintained to make the first and second substrates firmly bonded together.

[0041] The present invention realizes the automation of gluing and laminating, and can be operated in a continuous flow, which greatly improves the production efficiency and quality. The hot melt adhesive is a single-sided adhesive, and only one side of the substrate needs to be coated with the adhesive for laminating, which greatly saves labor and is a development trend of completely changing the process to save costs in the future, which is in line with industrial utilization and promotion. The present invention has a simple structure, low production cost, and is easy to use. The mechanical gluing and laminating greatly reduce the labor intensity of workers, which is in line with industrial promotion and application.

For those skilled in the art, many equivalent improvements and changes can be made to the above embodiments through logical analysis, reasoning or limited experiments without exceeding the concept and scope of the present invention, but these improvements and changes should all fall within the scope of protection required by the present invention.
