Description

Technical Field

[0001] This invention relates to the field of laminated glass manufacturing technology, specifically to a welding head assembly, a cloth-laying head, and a cloth-laying device. Background Technology

[0002] Currently, automotive windshields commonly use laminated glass, which consists of two layers of glass with a substrate such as PVB (polyvinyl butyral) sandwiched between them. To enable the windshield to defrost and receive radio signals, metal wires or strips need to be placed in the middle layer of the laminated glass. This is typically done by first uniformly welding the metal wires or strips onto a substrate made of insulating materials such as PVB using a fabrication machine, and then placing this substrate between the two glass layers for bonding.

[0003] Existing fabric weaving equipment typically employs ultrasonic welding heads or electric heating welding heads. Ultrasonic welding heads, due to their operating characteristics, suffer from uneven heating and unstable heating effects when used with thicker materials and complex curved surfaces. Furthermore, their complex structure makes their electronic components susceptible to vibration damage, resulting in a high failure rate. Electric heating welding heads, on the other hand, have fixed structures and dimensions, making them unsuitable for different types and sizes of metal wires or strips. This leads to suboptimal heating and welding results and can easily damage the substrate. In addition, existing fabric weaving equipment lacks real-time temperature monitoring and adjustment capabilities in its welding head assemblies. This results in insufficient melting temperature at the initial stage of fabric weaving, leading to insecure embedding of metal wires or strips, or excessively high temperatures during the weaving process, causing product scrap and increasing the product defect rate. Summary of the Invention

[0004] To address the technical problems of uncontrollable temperature, low product qualification rate, inability to replace welding heads, and poor welding effect in existing fabric feeding equipment welding head assemblies, this invention proposes a welding head assembly, a fabric feeding head, and a fabric feeding device. The heating core is equipped with a heating tube and a temperature sensor, which can monitor and adjust the temperature of the heating core and welding head in real time to ensure the required welding temperature.

[0039] Example 1:

[0040] like Figure 1-7As shown, this embodiment provides a welding head assembly 100 for hot-press welding materials 300 such as metal wires or metal strips onto a substrate. The welding head assembly 100 includes a heating core 1 and a welding head 2. The heating core 1 is the core body used for heating, and at least one heating tube 3 is fixedly mounted on it to convert electrical energy into heat energy to heat the heating core 1. The hot-welding method ensures stable heat output and uniform heating effect. The heating core 1 is also equipped with a temperature sensor 4 to monitor its temperature. The operation of the heating tube 3 can be adjusted based on the monitored temperature of the heating core 1, thereby maintaining the heating core 1 at the required temperature. Furthermore, the welding head 2 is detachably mounted to the heating core 1, optionally but not limited to, through a sleeve, threaded connection, or other methods. The temperature of the heating core 1 is transferred to the welding head 2, which can heat the material 300 such as metal wires or metal strips and press it into the substrate. The metal wire is a slender filament with a circular or nearly circular cross-section, the metal strip is a flat strip with a rectangular cross-section, the substrate can be, but is not limited to, PVB material, and both the heating core 1 and the welding head 2 are made of metal.

[0041] Thus, the welding head assembly 100 provided in this embodiment, compared with the prior art, has at least one heating tube 3 and a temperature sensor 4 fixedly installed on the heating core 1, thereby enabling real-time monitoring and adjustment of the temperature of the heating core 1 and the welding head 2. This ensures a suitable heating temperature throughout the entire material application process, guaranteeing reliable embedding of the metal wire or strip and preventing product scrap due to excessive temperature. Furthermore, the welding head assembly 100 of this embodiment features a detachable assembly structure for the heating core 1 and the welding head 2. The welding head 2 can be replaced according to the type and size of the material 300, such as the metal wire or metal strip. A welding head 2 suitable for the material 300 can be selected; for example, a welding head 2 with a smaller axial width can be selected for the metal wire, and a welding head 2 with a larger axial width can be selected for the metal strip. This ensures reliable thermoforming while preventing the welding head 2 from being too large, resulting in an excessively large contact area with the substrate during heating and thus overheating the substrate.

[0042] For the detachable mounting structure of welding head 2, such as Figure 1-2As shown, the heating core 1 in this embodiment is generally hollow cylindrical. A sleeve portion 11 is recessed on the outer wall of the heating core 1. A limiting step 12 is formed on one side of the sleeve portion 11, and several threaded holes 13 are provided on the other side of the sleeve portion 11, which can be threadedly connected to several clamping screws 14. The number of threaded holes 13 and clamping screws 14 is optional, but not limited to, two. The welding head 2 is generally annular. The welding head 2 can be sleeved on the sleeve portion 11. After sleeved, one end of the welding head 2 is limited and abutted by the limiting step 12, and the other end is pressed by the edge of the head of the tightened clamping screw 14, thereby fixing the welding head 2 to the heating core 1. The welding head 2 and the heating core 1 can move synchronously, for example, heating the material 300 such as metal wire or metal strip by rolling. The corresponding part of the substrate below the material 300 is heated and melted, and the material 300 can be embedded in the substrate. The installation structure of the welding head 2 and the heating core 1 makes disassembly and assembly convenient, and the contact area between the two is also large. The inner wall of the welding head 2 and the outer wall of the sleeve part 11 of the heating core 1 can preferably be fitted with a small clearance or a transition fit as needed. If necessary, protrusions and grooves can be provided on the side walls of the two to facilitate synchronous rotation of the two.

[0043] Furthermore, in this embodiment, a plurality of pressure grooves 15 are formed on the outer edge of the other end of the sleeve portion 11. Each pressure groove 15 has a corresponding threaded hole 13 on its bottom surface, and the threaded hole 13 does not protrude from the outer wall of the sleeve portion 11. The shank of the clamping screw 14 is connected to the threaded hole 13, and a portion of the head of the clamping screw 14 can be placed in the pressure groove 15. The protruding edge of the head of the clamping screw 14 from the outer wall of the sleeve portion 11 is used to clamp the welding head 2. By providing this pressure groove 15, this embodiment allows the head of the clamping screw 14 to be axially adjusted within the pressure groove 15 according to the axial dimension of the welding head 2, thus effectively clamping various welding heads 2 and ensuring a large contact area between the welding head 2 and the heating core 1.

[0044] For the installation of the heating tube 3 and the temperature sensor 4, this embodiment provides at least one first mounting hole 16 on the heating core 1, preferably multiple holes, and the specific number is optional but not limited to three. These first mounting holes 16 are evenly spaced along the circumferential direction, and each first mounting hole 16 corresponds to the installation of one heating tube 3. The heating tube 3 can be installed by snap-fit, adhesive, interference fit, etc. The heating core 1 also provides a second mounting hole 17, which is used to install the temperature sensor 4. The temperature sensor 4 can be, but is not limited to, a thermocouple, and can be installed by snap-fit, adhesive, interference fit, etc. The first mounting hole 16 and the second mounting hole 17 need to avoid the aforementioned pressure groove 15, and are preferably through-holes. This method embeds the heating tube 3 and the temperature sensor 4 inside the heating core 1, which can better heat the heating core 1 and monitor the temperature.

[0045] The welding head assembly 100 in this embodiment further includes an adapter plate 5, a fixed shaft 51, and bearings. One end of the fixed shaft 51 is fixed to the adapter plate 5, for example, by means of a screw connection. The other end of the fixed shaft 51 is connected to the heating core 1 via a bearing, so that the heating core 1 and the welding head 2 can rotate synchronously relative to the fixed shaft 51. Specifically, the bearings include a first bearing 52 and a second bearing 53. One end of the fixed shaft 51 is fixed to the adapter plate 5, and the other end is sequentially fitted with the first bearing 52, the heating core 1, and the second bearing 53. One end of the first bearing 52 is limited by a shoulder 511 provided on the fixed shaft 51, and the other end of the first bearing 52 is limited by one end of a flange 18 provided in the inner hole of the heating core 1. One end of the second bearing 53 is limited by the other end of the flange 18, and the other end of the second bearing 53 is limited by a retaining spring or other retaining element 54 that is inserted into the fixed shaft 51. This structure facilitates the installation of the heating core 1, and the force can be shared by two bearings, making the movement of the heating core 1 and the welding head 2 more stable.

[0046] The welding head assembly 100 also includes a conductive slip ring 55. The stationary portion of the conductive slip ring 55 is fixed to the adapter plate 5. The conductive slip ring 55 is a through-hole conductive slip ring, and the fixed shaft 51 passes through the central through-hole of the conductive slip ring 55. The rotating portion of the conductive slip ring 55 is connected to the leads at the rear ends of the heating tube 3 and the temperature sensor 4. When the heating core 1 and the welding head 2 rotate, the heating tube 3 and the temperature sensor 4 will also rotate accordingly. By setting the conductive slip ring 55, the leads can be prevented from tangling and being damaged.

[0047] like Figure 4-6 As shown, the welding head assembly 100 also includes a guide wheel 61, a material clamping module 62, and a material clamping plate 63 located on the side of the welding head 2. A material tray 65 is positioned above the welding head 2, on which the metal wire or metal strip to be welded is wound. The material tray 65 is mounted on a mounting shaft 66 and its position can be adjusted axially to be as flush as possible with the welding head 2, for example, directly above it. The metal wire or metal strip on the material tray 65 is led to the outer periphery of the welding head 2 after passing through the guide wheel 61. The material tray 65 may have a certain rotational damping. The guide wheel 61 is used for guiding and tensioning. The heating core 1 and the welding head 2 can be connected... Figure 5-6 The view shown scrolls clockwise.

[0048] Furthermore, a boss 21 is formed in the middle of the outer periphery of the welding head 2, and a guide groove 631 is provided at the end of the pressure plate 63. Preferably, the guide groove 631 is approximately U-shaped to accommodate different types of materials 300. The pressure module 62 can drive the pressure plate 63 to extend outwards, with the end of the pressure plate 63 moving towards the lower right side of the welding head 2. The boss 21 extends into the guide groove 631, and the metal wire or metal strip is located between the outer surface of the boss 21 and the inner bottom surface of the guide groove 631. Through the guide groove 631 and the boss 21, the material 300 can be guided during the rolling forward of the welding head 2, thereby ensuring that the material 300 is accurately embedded into the substrate. The pressure plate 63 is detachably mounted on the moving part of the pressure module 62, so the appropriate pressure plate 63 can be selected and replaced according to the specific material 300. The welding head 2 can also be replaced to adapt to the material 300. The axial width of the boss 21 of the welding head 2 can be slightly larger than the width of the material 300 and slightly smaller than the groove width of the guide groove 631. While ensuring that the material 300 is reliably pressed into the substrate, it can also ensure a small contact area between the boss 21 of the welding head 2 and the substrate, preventing damage caused by overheating of the substrate. Preferably, the inner bottom surface of the guide groove 631 of the pressure plate 63 can press against the metal wire or metal strip, that is, the pressure module 62 can drive the pressure plate 63 to extend to adjust the degree of contact between the metal wire or metal strip and the outer periphery of the boss 21 of the welding head 2, thereby allowing the metal wire or metal strip to spread out, which is convenient for subsequent hot pressing welding. The pressure module 62 can be, but is not limited to, a pressure cylinder.

[0049] In other embodiments, a shallow groove (not shown in the figure) may be provided on the outer periphery of the welding head 2 to accommodate and guide the material 300 such as the metal wire or metal strip.

[0050] like Figure 1 , 3 As shown in Figure 4, the welding head assembly 100 in this embodiment also includes a pressing module 7, which can drive the adapter plate 5 to move up and down. The guide wheel 61 and the pressing module 62 are connected to the adapter plate 5 through the connecting plate 64 and move synchronously with the adapter plate 5. When the heating core 1 and the welding head 2 are heated to a suitable temperature, the pressing module 7 drives the adapter plate 5 and its components such as the heating core 1 and the welding head 2 to move downward, hot-pressing the metal wire or metal strip onto the substrate below. The pressing module 7 is preferably a pressing cylinder, controlled by an electro-proportional valve 92 to ensure the pressing force and position.

[0051] As can be seen from the above, the welding head assembly provided in this embodiment can monitor and adjust the temperature of the heating core and welding head in real time, ensuring stable welding effect and reducing product defect rate. In addition, it also has the characteristics of good adaptability, convenient disassembly and assembly, and reliable operation.

[0052] Example 2:

[0053] like Figure 3-9 As shown, this embodiment provides a fabric feeding head 200, which includes a welding head assembly 100 as described in Embodiment 1.

[0054] The fabric feeding head 200 also includes a first support 8 and a second support 9. The first support 8 is equipped with the aforementioned welding head assembly 100 and a cutting assembly 81. The cutting assembly 81 is used to cut the material 300 when the current welding is completed, and includes a cutting cylinder and a cutting blade. The second support 9 is equipped with a temperature controller 91, preferably an intelligent PID temperature controller. The aforementioned temperature sensor 4 monitors the temperature of the heating core 1 and feeds it back to the temperature controller 91. The temperature controller 91 controls at least one of the aforementioned heating tubes 3 to heat the heating core 1 to the required set temperature. The second support 9 is also equipped with the aforementioned electro-proportional valve 92.

[0055] Furthermore, the second support 9 is also equipped with a vertical linear module 93, which can drive the second support 9 and the first support 8 to move vertically together. The second support 9 is also equipped with a rotating module 94, which includes a servo motor 941 and a hollow rotating platform 942. The hollow rotating platform 942 allows the first support 8 to rotate horizontally relative to the second support 9, and allows the air pipe of the pressing cylinder, the cable of the stationary portion of the conductive slip ring 55, and the air pipes and cables of the solenoid valves 82 of the cutting cylinder and the pressing cylinder to pass through. A slip ring 95 is also provided on the second support 9, corresponding to the hollow rotating platform 942. The rotating portion of the slip ring 95 is connected to the air pipes and cables, and the stationary portion is connected to the electro-proportional valve 92, the temperature controller 91, the main controller, etc. The second support 9 is also equipped with a cover 96 to protect the temperature controller 91, the electro-proportional valve 92, the rotating module 94, and the slip ring 95.

[0056] Example 3:

[0057] This embodiment provides a fabric laying device, which includes a fabric laying head 200 as described in Embodiment 2. The fabric laying device also includes a processing platform (not shown in the figure) and an XY horizontal linear module (not shown in the figure). The processing platform is used to lay the substrate, and the XY horizontal linear module is equipped with the fabric laying head 200. The XY horizontal linear module can drive the fabric laying head 200 to move horizontally along the X and Y directions. Since the vertical linear module 93 in the fabric laying head 200 can drive the welding head 2 to move vertically (i.e., along the Z-axis), and the rotation module 94 in the fabric laying head 200 can drive the welding head 2 to rotate along the Z-axis, this embodiment enables the welding head 2 to move along the X, Y, and Z axes, and also to rotate along the Z-axis. This is suitable for substrates with complex curved surfaces and different thicknesses, allowing for free fabric laying trajectories and meeting the needs of different fabric patterns.

[0058] In this embodiment, the material feeding device first selects and assembles the appropriate welding head 2 and pressure plate 63 according to the current material 300, such as metal wire or metal strip. Then, the heating tube 3 heats the heating core 1 and welding head 2, and the temperature signal is converted into an electrical signal by the temperature sensor 4, which is fed back to the temperature controller 91 for temperature monitoring and adjustment. Material feeding can begin when the heating core 1 and welding head 2 reach the set temperature. Next, the electric proportional valve 92 controls the downward pressure of the pressing cylinder to ensure appropriate downward pressure on the welding head 2, using high temperature to press the material 300 into the substrate. During the feeding process, the welding head 2 moves along the feeding trajectory under the action of the XY horizontal linear module, the vertical linear module 93, and the rotating module 94. When it reaches the end position of the feeding, the welding head 2 lifts up, the cutting component 81 cuts the material 300, and then lifts up again. This cycle repeats, achieving automatic material feeding.

[0059] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
