Description

Technical Field

[0001] This invention relates to the field of automotive parts manufacturing technology, and in particular to a contact heating and bonding device. Background Technology

[0002] In recent years, with the advancement of clean energy transformation, new energy vehicles have become a major trend in the industry, and the demand for vehicle lightweighting has become increasingly urgent. At the same time, the public's aesthetic requirements for car appearance are constantly improving, which has led to the increasingly widespread application of aluminum alloy trim panels in the automotive field.

[0003] Research has found that during the assembly of aluminum alloy trim panels, clips are usually required to secure them to the vehicle. At this point, the bonding quality between the clips and the aluminum alloy trim panels using adhesive is a key factor affecting product performance and appearance. OEMs have imposed stringent requirements on the stability of the bonding performance and the flatness and flawlessness of the aluminum parts' surface.

[0004] Currently, the industry commonly uses a direct-heating method with a hot air gun to bond aluminum alloy trim clips. This method involves directly heating the clip's bonding area with a hot air gun nozzle, followed by applying adhesive to attach the clip directly to the aluminum alloy trim. While this achieves basic heating, it still has significant drawbacks: (1) The heat transfer efficiency is low, and the temperature transferred to the clip is significantly affected by the ambient temperature and the distance between the hot air gun and the clip, which directly leads to poor heating stability. (2) The heating process parameters for the clips need to be frequently adjusted according to the ambient temperature, which affects production efficiency; (3) The outer shell of the hot air gun is mostly made of plastic. Long-term use can easily cause the outer shell to soften and deform due to overheating, burn itself, and cause serious safety hazards. (4) The hot air gun heats with the rated power, and the temperature is uncontrollable. It is easy for the heating temperature to be too high or too low. If it is too high, the adhesive will fail to perform during the curing process. If it is too low, the adhesive cannot be effectively cured, thus affecting the assembly accuracy. In addition, under certain surface treatment processes, uneven heating or abnormal temperature may cause quality defects such as film marks on the product appearance.

[0005] Therefore, it is evident that, in response to the problems of unstable heating, low efficiency, significant safety hazards, and high quality risks in the existing hot air gun direct-blowing heating and bonding method, there is an urgent need to design a heating and bonding device that can achieve high-precision temperature control, improve heating efficiency, reduce safety risks, and ensure bonding quality. Summary of the Invention

[0006] The technical problem to be solved by the present invention is that the present invention discloses a contact heating and bonding device to solve the problems of unstable heating, low efficiency, great safety hazards and high quality risks that exist in the existing method of using a hot air gun to directly heat the clips to bond to aluminum alloy decorative panels.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a contact heating and bonding device, comprising a positioning component for installing and positioning a decorative panel to be installed, and a contact heating component disposed on the positioning component. The contact heating component includes a first heating component and a second heating component, which are respectively disposed on opposite sides of the decorative panel to be installed. The first heating component is provided with a clip, which drives the clip to move closer to or further away from one side of the decorative panel to be installed, and heats the clip in contact with the decorative panel. The second heating component is used to heat the decorative panel in contact on the other side of the decorative panel to be installed.

[0008] Furthermore, in the contact heating bonding device of the present invention, the first heating component includes a support base and a lifting platform.

[0010] Furthermore, in the contact heating and bonding device of the present invention, the first heating component further includes a lifting cylinder, which is disposed on the support base and the output end of the lifting cylinder is connected to the lifting platform to drive the lifting platform to move closer to or away from the side of the decorative panel to be installed.

[0011] Furthermore, in the contact heating and bonding device of the present invention, the second heating component includes a mounting base and a rotary cylinder disposed on the mounting base. The output shaft of the rotary cylinder is connected to a support arm, and one end of the support arm is connected to a second heating block. The rotary cylinder is used to drive the output shaft to rotate around its own axis and simultaneously drive the support arm and the second heating block to rotate, so that the second heating block is pressed onto the other side surface of the decorative panel to be installed.

[0012] Furthermore, in the contact heating bonding device of the present invention, at least one of the first heating component and the second heating component is also provided with a temperature sensor.

[0013] Furthermore, the contact heating bonding device of the present invention also includes a controller, which is electrically connected to the first heating component and the second heating component respectively; wherein, the controller is used to control the heating temperature and working status of the first heating component and the second heating component.

[0014] Furthermore, in the contact heating bonding device of the present invention, the positioning component includes an end positioning member and a side positioning member. The end positioning member is used to lock and position the left and right ends of the decorative panel to be installed in the horizontal direction, and the side positioning member is used to lock and position the side edge of the decorative panel to be installed.

[0015] Furthermore, in the contact heating bonding device of the present invention, the end positioning member is also provided with an end positioning detector, which is used to detect whether the decorative panel to be installed is installed and positioned in a preset position.

[0016] Furthermore, in the contact heating and bonding device of the present invention, the side positioning member is provided with an elastic limiting mechanism.

[0020] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0021] like Figure 1 , Figure 2 and Figure 8As shown, this invention designs a novel contact heating and bonding device, which specifically includes: a positioning component 3 for installing and positioning the decorative panel 6 to be installed, and a contact heating component disposed on the positioning component 3. A key feature of this invention is that the contact heating component is specifically configured to include a first heating component 1 and a second heating component 2, so that the first heating component 1 and the second heating component 2 respectively perform contact heating on the clip and the decorative panel 6 to be installed, thereby optimizing the heating effect, improving the heating and bonding quality between the clip and the decorative panel 6 to be installed, and avoiding the problems of unstable heating, low efficiency, significant safety hazards, and high quality risks associated with traditional hot air gun heating and bonding methods.

[0022] See Figure 8 As shown, and in conjunction with references Figure 1 and Figure 2 In practical applications, the first heating component 1 and the second heating component 2 can be arranged one-to-one with each other and respectively on opposite sides of the decorative panel 6 to be installed, so that the first heating component 1 and the second heating component 2 can better perform contact heating, and the decorative panel 6 to be installed and the clip can be preheated evenly.

[0023] Specifically, the first heating component 1 is provided with a clip. The first heating component 1 can drive the clip to approach or move away from one side of the decorative panel 6 to be installed, such as the inner side of the decorative panel 6 to be installed. When the clip is driven to contact the decorative panel 6 to be installed, the first heating component 1 can perform contact heating on the clip.

[0024] Correspondingly, the second heating component 2 is used to heat the decorative panel 6 to be installed on the other side of the decorative panel 6 in contact. In actual application, it can specifically heat the outer side of the decorative panel 6 to be installed, that is, the outer surface of the decorative panel 6 to be installed.

[0025] See Figure 1 and Figure 2 As shown, in practical applications, considering that multiple clips may need to be installed on a single decorative panel 6 to facilitate the subsequent fixing of the decorative panel 6 to the vehicle; in the contact heating bonding device designed in this invention, multiple contact heating components can be specifically set on the above-mentioned positioning component 3 to speed up the production process and install multiple clips on the decorative panel 6 at one time.

[0026] like Figure 3 , Figure 4As shown, in this invention, in order to facilitate the control of the lifting and lowering of the aforementioned clip, the first heating component 1 of the contact heating bonding device includes a support base 11, a lifting platform 12, and a lifting cylinder 14. The lifting cylinder 14 is fixedly mounted on the support base 11, and the lifting platform 12 is slidably mounted on the linear guide rail 15 of the support base 11. The lifting platform 12 is provided with a first heating block 13, and the first heating block 13 is provided with the aforementioned clip. The output end of the lifting cylinder 14 is connected to the lifting platform 12 to drive the lifting platform 12 to slide along the extension direction of the linear guide rail 15 on the support base 11, thereby moving closer to or away from the side of the decorative panel 6 to be installed.

[0027] In other words, under the drive of the lifting cylinder 14, the lifting platform 12 can be driven to move together with the first heating block 13 and the clips set on the first heating block 13, and the clips can be made to contact one side of the decorative panel 6 to be installed, thereby triggering the first heating block 13 to heat the clips in contact, which facilitates the bonding of the clips.

[0028] It should be noted that, in practical applications, when installing the clip on the first heating block 13 of the first heating component 1, a limiting buckle and a magnet can be specifically provided on the lifting platform 12. The magnet is used to attract the clip, preventing displacement during the lifting process. Simultaneously, the limiting buckle is used to match and engage with the clip, thereby locking the clip's position and ensuring that the clip is subsequently accurately adhered to the designated position on the decorative panel 6 to be installed. Before installing and positioning the clip, adhesive needs to be applied to the clip to facilitate subsequent adhesion between the clip and the decorative panel 6.

[0029] In addition, in practical applications, in order to prevent the temperature of the entire lifting platform 12 from rising due to its own heating when the first heating block 13 is placed on the lifting platform 12, thus affecting power consumption, a heat insulation block 16 can be specifically set between the installation position of the first heating block 13 and the lifting platform 12, so as to isolate the heat conduction process of the first heating block 13 to the lifting platform 12.

[0030] Accordingly, such as Figure 5 , Figure 6As shown, in this invention, in order to avoid affecting the installation and positioning of the decorative panel 6 to be installed on the positioning component 3, while simultaneously enabling contact heating of the other side of the decorative panel 6 to be installed using the second heating component 2, the second heating component 2 may specifically include: a mounting base 21 and a rotary cylinder 22 disposed on the mounting base 21. The output shaft 23 of the rotary cylinder 22 extends along the vertical height direction, and the output shaft 23 of the rotary cylinder 22 is connected to a support arm 24. One end of the support arm 24 is connected to a second heating block 25. The rotary cylinder 22 is used to drive the output shaft 23 to rotate around its own axis, and simultaneously drive the support arm 24 and the second heating block 25 to rotate, so that the second heating block 25 is pressed against the other side surface of the decorative panel 6 to be installed.

[0031] In other words, in practical applications, the rotary cylinder 22 can control the support arm 24 and the second heating block 25 to rotate, so that the support arm 24 and the second heating block 25 can switch between the avoidance position and the heating position. When it is necessary to install the positioning decorative panel 6 on the positioning component 3, the rotary cylinder 22 can control the support arm 24 and the second heating block 25 to rotate to the avoidance position to avoid the outer contour dimensions of the decorative panel 6. When it is necessary to heat the decorative panel 6, the rotary cylinder 22 can control the support arm 24 and the second heating block 25 to rotate to the heating position. At this time, the second heating block 25 is positioned opposite the first heating block 13 and is specifically located on the other side surface of the decorative panel 6 to perform contact heating of the decorative panel 6.

[0032] When the first heating block 13 and the second heating block 25 are used to heat the clip and the decorative panel 6 to be installed in contact, the lifting cylinder 14 of the first heating component 1 can output a continuous and stable pressure to drive the first heating block 13 and the clip provided on the first heating block 13 to press against the decorative panel 6 to be installed. The second heating block 25 on the other side surface of the decorative panel 6 to be installed can cooperate with the first heating block 13 to press the clip and the decorative panel 6 to be installed, so as to ensure that the lifting cylinder 14 can effectively pre-tighten the matching relationship between the clip and the decorative panel 6 to be installed when outputting stable pressure, and ensure the heating and bonding quality of the two.

[0033] Of course, in order to improve the safety of the entire contact heating and bonding device and avoid the problem of burns to operators that may occur when the second heating block 25 is rotated, a protective sleeve 26 can be provided on the second heating block 25 for protection.

[0034] It should be noted that, in order to further improve the user experience of this contact heating bonding device, at least one of the first heating component 1 and the second heating component 2 is also provided with a temperature sensor 4 to detect the corresponding heating temperature. For example, in practical applications, the temperature sensor 4 can be specifically installed on the first heating block 13 and the second heating block 25, and the temperature sensor 4 can be used to detect the heating temperature of the first heating block 13 and the second heating block 25. In this case, a controller can also be specifically provided on the contact heating bonding device, and the controller is electrically connected to the temperature sensors 4 on the first heating block 13, the second heating block 25, and the first heating block 13 and the second heating block 25, respectively. The external air source is used to supply air to the lifting cylinder 14 in the first heating component 1 and the rotating cylinder 22 in the second heating component 2, thereby controlling the heating temperature of the first heating component 1 and the second heating component 2 through the controller.

[0035] In other words, in practical applications, based on the actual temperature data of the first heating block 13 and the second heating block 25 detected and fed back by the temperature sensor 4, the controller can compare it with the preset temperature and specifically output a cooling command or a heating command to the first heating block 13 or the second heating block 25 to control the first heating block 13 or the second heating block 25 to heat up or cool down.

[0036] Meanwhile, it should be noted that, in order to facilitate the control of the working state of each cylinder in the first heating component 1 and the second heating component 2, a speed regulating valve 5 can be provided on the lifting cylinder 14 of the first heating component 1 and the rotating cylinder 22 of the second heating component 2. The controller can further control the speed regulating valve 5 to control the working state of the first heating component 1 and the second heating component 2, thereby simplifying the operation difficulty for the operator.

[0037] Correspondingly, in the contact heating and bonding device designed in this invention, the positioning component 3 is also crucial for the installation and positioning process of the decorative panel 6 to be installed, as it directly affects the installation accuracy of the subsequent clips and the bonding effect of the subsequent clips.

[0038] In addition, such as Figure 1 As shown, in order to ensure excellent installation and positioning effect of the decorative panel 6 to be installed, in practical application, the positioning component 3 is specifically set to include a base plate 31 and two end positioning members 32 and multiple side positioning members 33 provided on the base plate 31. The two end positioning members 32 are respectively provided at the left and right ends of the decorative panel 6 to be installed, so as to lock and position the left and right ends of the decorative panel 6 to be installed in the horizontal direction; while the multiple side positioning members 33 can be arranged sequentially to match the outer contour of the side of the decorative panel 6 to be installed, so as to lock and position the side edge of the decorative panel 6 to be installed.

[0039] To ensure accurate installation positioning, an end positioning detector can be provided on the end positioning component 32. The end positioning detector is used to detect whether the decorative panel 6 to be installed is installed and positioned in the preset position. For example, in some embodiments, the end positioning detector is only triggered when the decorative panel 6 to be installed comes into contact with the end positioning detector, thereby determining that the decorative panel 6 to be installed is installed and positioned in the preset position. At this time, the controller can control the first heating component 1 and the second heating component 2 to carry out the subsequent process.

[0040] It is important to note that, such as Figure 7 As shown, in order to ensure that the positioning of the side of the decorative panel 6 to be installed can be pressed to the reference point each time, and to ensure consistent accuracy in each placement, an elastic limiting mechanism 331 is specifically provided on the side positioning component 33 in actual application. The elastic limiting mechanism 331 includes a positioning seat 332 and a positioning post 333 telescopically provided on the positioning seat 332. A spring 334 is wound on the positioning post 333, and one end of the spring 334 abuts against the positioning post 333, and the other end of the spring 334 abuts against the positioning seat 332. By increasing the limiting of the spring 334 and the positioning post 333, the locking and positioning effect of the side of the decorative panel 6 to be installed is improved, and the positioning accuracy is ensured.

[0041] Therefore, using the contact heating bonding device designed in this invention to perform contact heating bonding of clips and aluminum alloy decorative panels has at least the following advantages: (1) Optimize the heating method by changing the direct blowing heating of the hot air gun to contact heating, reducing the heat loss caused by distance and air temperature, so that the heat transferred to the clip is stable each time. The heating temperature of the first heating block 13 and the second heating block 25 measured by the thermometer can be controlled to fluctuate within ±5℃ of the preset temperature, thereby obtaining more accurate heating process parameters and ensuring the heating effect.

[0042] (2) Reduce the frequency of switching process parameters, unify process parameters, and reduce quality problems caused by omissions in the field from the root.

[0043] (3) Eliminate safety hazards and material loss caused by overheating or aging of hot air guns.

[0044] (4) The first heating component 1 and the second heating component 2 heat the clip and the decorative panel 6 to be installed respectively to improve the performance stability of the glue after curing and improve the film imprint phenomenon on the product surface.

[0045] In summary, the contact heating and bonding device designed in this invention, by adding a contact heating component, utilizes the cooperation of the first heating component 1 and the second heating component 2 to press the clip and the decorative panel 6 to be installed onto opposite sides, and respectively heats the clip and the decorative panel 6 through contact heating, and precisely controls the heating temperature of each heating component to reduce appearance defects of the finished product, thereby effectively reducing heat loss, improving heating efficiency, and accurately controlling temperature. It can avoid the safety hazards and material loss of traditional heating with a hot air gun, effectively prevent film imprinting on the decorative panel, and ensure that the heated clip and aluminum alloy decorative panel are stably bonded by adhesive, thereby improving assembly accuracy and appearance quality. It has good prospects for promotion and application value.
