Description

Technical Field

[0001] The present invention relates to a cloth wrapping device, specifically to a device and an operation method for hot pressing a mesh cloth on the surface of a product and laser cutting the auxiliary mesh cloth. Background Art

[0002] The cloth wrapping process is a newly emerging appearance decoration process in recent years. Different from the previous processes where the product directly uses a plastic shell as the appearance surface, plastic shell painting, and plastic shell electroplating, the surface of these processes is prone to scratching and fingerprint marks. The cloth wrapping process has a comfortable hand feeling, is more upscale, delicate, and closer to the aesthetic of human-wearing fabrics visually, and there is no need to worry about scratching and fingerprint marks affecting the visual effect. It is mainly applied to the outer surfaces of Bluetooth smart speaker casings, VR glasses, VR game smart devices, mobile phone cases, home theater speaker casings, high-end tablet computer cases, as well as the hot pressing of the hems of high-end underwear and panties.

[0003] The traditional methods and their defects are as follows:

[0004] 1. The traditional method uses a simple cloth wrapping machine. After hot pressing the mesh cloth on the product surface with the simple cloth wrapping machine table, excess auxiliary fabric is generated. It is necessary to manually put the product into another specific tooling fixture, arrange the excess auxiliary fabric, cover it with a shaping fixture, and then use another laser cutting machine to cut off the excess auxiliary fabric, resulting in low production efficiency. In addition, the number of devices and toolings is large, the power consumption is high, and the floor area occupied is large, indirectly increasing the processing cost. After hot pressing, a conveyor belt or a blister box is required for transfer and caching.

[0005] 2. It is necessary to manually place the shell to be wrapped with the mesh cloth and the mesh cloth on the fixture, and full-automatic production cannot be achieved. The traditional method has numerous processes, and manual operation cannot ensure product uniformity, resulting in a low yield, and the mesh cloth must be manually arranged before cutting. Summary of the Invention

[0086] A first lifting power source 21 installed in the middle of the top end of the main structural frame 2;

[0087] A first lifting plate 31 sleeved on the guide posts at four corners. The two sides of the first lifting plate 31 are provided with avoidance notches, and a mounting hole is provided in the middle thereof;

[0088] The upper jig head assembly 43 fixed at the mounting hole. The upper end of the upper jig head assembly 43 is connected to the driving end of the first lifting power source 21 and includes an upper jig head provided at the lower end of the upper jig head assembly 43.

[0089] Preferably, the upper jig head assembly 43 further includes a heating part. The heating part is arranged at the upper jig head and heats the upper jig head by generating heat through electricity. The upper jig head is sleeved with a heat-conducting silica gel sleeve with a heat-conducting function.

[0090] Preferably, the cloth clamping mechanism 4 includes:

[0091] A second lifting plate 41 sleeved on the guide posts at four corners, and a first through hole for the lower end of the upper jig head assembly 43 to pass through is provided in the middle thereof;

[0092] Two sets of third power sources 42 and two sets of fourth power sources 22, wherein the two sets of third power sources 42 are symmetric with respect to the first through hole and are fixed on both sides of the upper plate surface of the second lifting plate 41;

The second lifting plate 41 is lifted and lowered by the pressure difference between the two sets of third power sources 42 and the two sets of fourth power sources 22.

[0094] The main function of the cloth clamping mechanism 4 is to use the reverse force of the cloth supporting mechanism to clamp the mesh cloth and continue to move downward to offset the reaction force of the cloth supporting layer, so as to tightly attach the mesh cloth to the outer surface of the product without wrinkles.

[0099] Embodiment 3:

[0100] The operation method of the device of the present invention, and the operation method includes the following steps:

[0101] Step 1, place the product to be processed with a mesh cloth on the lower tool head, and pre-spray hot melt adhesive on the surface of the product;

[0102] Step 2, lay the mesh cloth flat in the second through hole of the third lifting plate 51, and the mesh cloth covers the second through hole and extends to the outer periphery of the second through hole;

[0103] Step 3, utilize the pressure difference between the cloth clamping mechanism 4 and the cloth supporting mechanism 5, that is, the downward pressure of the cloth clamping mechanism 4 is greater than the supporting force of the cloth supporting mechanism 5, to clamp the mesh cloth and move it downward, and tension the mesh cloth and pre-press part of the mesh cloth on the surface of the product without wrinkles;

After the mesh cloth is heated, the mesh cloth is tightly attached to the surface of the product;

[0105] Step 5: The heat in step 4 causes the hot melt adhesive on the surface of the product to melt and adhere to the mesh and keep it in close contact for a period of time, maintaining a constant temperature. The period of time here refers to 12 to 17 seconds (the time required for the hot melt adhesive to activate), and the set temperature is 70 to 110°C (the temperature required for the hot melt adhesive to melt).

[0106] Step 6: Use the laser cutting board to shape the mesh into the specified shape required for cutting, and then set the interpolation trajectory according to the various shapes of the product. The XY axis drive mechanism drives the laser cutter 131 to move and cooperates with the synchronous rotation mechanism to cut off the excess auxiliary mesh waste. The synchronous rotation mechanism avoids the laser emitted by the laser cutter 131 by rotating the turntable.

[0107] Example 4:

It is convenient for equipment maintenance personnel to quickly find equipment with abnormal operation during the production process in a large workshop. Under normal circumstances, it will display a green light; the equipment will display a yellow light in the debugging state; and a red light will be displayed when the equipment is operated incorrectly or has an abnormal fault.

[0109] Example 5:

[0110] Since the loading and unloading ports of the cabinet of the present invention require manual loading and unloading, for safe operation, a through-beam safety grating 12 is installed on both sides of the loading and unloading ports. The main function of the through-beam safety grating 12 is to prevent operators from accidentally putting their hands or heads into the equipment during the production process and causing injuries. When the safety grating is accidentally triggered, the equipment will suspend all actions to ensure the safety of personnel and equipment.

[0111] Example 6:

[0112] An operation panel with a human-machine interface (HMI) is located on the upper front of cabinet 1. This HMI controls the entire machine and can also operate individual components. A precision pressure regulating valve adjusts the cylinder's output force. A temperature control switch and thermostat control the heating on and off, with the latter providing a digital display for temperature control.

[0113] A control box 7 is provided on the lower side of the loading and unloading port. The control box 7 has an emergency stop switch and a two-hand synchronization button. It is used for manual loading and unloading during semi-automatic production and serves as an input for human-machine interaction signals. In addition, there is an emergency stop button function in special circumstances or when an operation error occurs.

[0114] Example 7:

[0115] The lower part of the cabinet 1 is mainly used to support the overall machine structure and install control electrical and cylinder control components; the two-component unit is mainly used to adjust the air pressure and filter out moisture and oil mist in the air source; the casters are mainly used to facilitate normal handling and movement.

[0116] On one side of the lower part of the cabinet 1, a heat dissipation fan system 11 is provided. The heat dissipation fan system 11 dissipates heat to improve the service life of the equipment.

[0117] Embodiment 8:

[0118] The equipment process flow of the present invention is as follows:

[0119] 1. Place the product on the lower jig head: Place the product on the lower jig and check if it is properly placed.

[0120] 2. Press the start button with both hands for the first time. The cloth supporting layer places the mesh cloth. After pressing the start button with both hands for the first time, the cloth supporting layer moves upward to the limited position, and the mesh cloth is placed at the limited position.

[0121] 3. Press the start button with both hands for the second time - the cloth clamping layer presses down the cloth supporting layer. After pressing the start button with both hands for the second time, the cloth clamping layer moves downward to clamp the mesh cloth (using the reverse force of the cloth supporting layer to clamp the mesh cloth to the cloth clamping layer and continue to move downward to offset the reaction force of the cloth supporting layer to pre-paste the mesh cloth on the outer surface of the product without wrinkles).

[0122] 4. The cloth wrapping layer presses down to start hot-pressing the cloth and maintains the set time - the laser cutter 131 turns on the laser. After the cloth clamping layer cylinder detects in place, the cloth wrapping layer moves downward to start hot-pressing the cloth and maintains the set time and cuts the mesh cloth into the required shape by laser. The laser anvil, the cloth supporting layer, and the cloth clamping layer sort out the mesh cloth into the shape to be cut. The laser cutter runs to the position to be cut. According to the set interpolation trajectory, the laser on the XY platform is driven and cooperates with the synchronous rotation mechanism to cut off the redundant auxiliary mesh cloth waste, and a multi-angle air extraction structure is used to extract the smoke.

[0123] 5. The cloth wrapping layer resets upward.

[0124] 6. The cloth supporting layer resets downward.

[0125] 7 The cloth clamping layer resets upward.

[0126] 8. Take out the product and the redundant mesh cloth.

[0127] 9 The process is completed.

4. A method for operating a device for hot-pressing a mesh fabric on the surface of a product and laser-cutting the mesh fabric for assistance, characterized in that, It includes the device according to any one of claims 1-3.

5. The operating method according to claim 4, characterized in that, This operation method includes the following steps: Step 1, place the product to be processed with the overlaid mesh fabric on the lower jig head, and pre-spray hot melt adhesive on the surface of the product. Step 2, lay the mesh fabric flat in the second through hole of the third lifting plate (51). The mesh fabric covers the second through hole and extends to the outer periphery of the second through hole. Step 3, utilize the pressure difference between the cloth clamping mechanism (4) and the cloth supporting mechanism (5), that is, the downward pressure of the cloth clamping mechanism (4) is greater than the supporting force of the cloth supporting mechanism (5), clamp the mesh fabric and move it downward, and pre-press part of the mesh fabric tightly and wrinkle-free on the surface of the product. Step 4, the cloth wrapping mechanism (3) drives the upper jig head assembly (43) to press down on the product tightly. The heat generated by the upper jig head is transferred to the mesh fabric through the heat-conducting silica gel sleeve that has the function of protecting the mesh fabric. After the mesh fabric is heated, it is closely attached to the surface of the product. Step 5, the heat in Step 4 causes the hot melt adhesive on the surface of the product to melt and bond with the mesh fabric and remain in a closely attached state for a period of time, maintaining a constant temperature. Step 6, use the laser anvil to shape the mesh fabric into the specified shape required for cutting. Then, set the interpolation trajectory according to the various shapes of the product. The XY-axis driving mechanism drives the laser cutter (131) to move, and cooperate with the synchronous rotation mechanism to cut off the redundant auxiliary mesh fabric waste. The synchronous rotation mechanism rotates the turntable to avoid the laser emitted by the laser cutter (131).
