Description

Technical Field

[0001] This application relates to the field of adhesive application technology for automotive structural components, specifically a novel automated adhesive application mechanism for automotive structural components. Background Technology

[0002] The existing automated adhesive application for automotive structural components is mainly used to precisely apply adhesive to the connection and sealing parts of automotive structural components. Through automated operation, the adhesive layer is ensured to be uniform and the position is accurate, so as to realize the functions of sealing, fixing or preventing leakage of structural components, improve the stability and safety of automotive structures, and improve production efficiency.

[0003] However, due to the wide variety of automotive structural parts and the significant differences in positioning references and fixing requirements for different parts, the working platform of the automated glue dispensing mechanism is usually a fixed structure. For automotive structural parts of different shapes and sizes, a lot of adjustments need to be made to the positioning and clamping components on the platform, or even the entire working platform needs to be replaced. This is not only cumbersome to operate, but also consumes a lot of changeover time. Furthermore, some existing mechanisms have unreasonable part positioning blocks or poor clamping force and method of clamping components, which makes it easy for parts to move or shift during platform movement or glue application. Since the positioning blocks are not precisely designed according to the specific shape and size of the parts, they cannot provide reliable positioning. The structural defects of the clamping components may lead to insecure clamping, which in turn affects the accuracy of the glue application position and reduces the glue application quality. Utility Model Content

[0004] The purpose of this invention is to provide a novel automated glue application mechanism for automotive structural components to solve the problems mentioned in the background art.

[0005] The technical solution adopted by this application to solve its technical problem is: A novel automated glue-applying mechanism for automotive structural components includes a mechanism tooling body, on which a first working platform is slidably connected via a guide rail assembly. The first working platform moves linearly on the top surface of the mechanism tooling body via a drive assembly. A replacement platform is detachably installed on the first working platform. The replacement platform includes a support base and a second working platform. The bottom sides of the second working platform are fixedly installed to the support base, and the support base is inserted into the first working platform. Multiple part positioning blocks are fixedly installed on both the first and second working platforms. The first working platform has a first mounting slot, and the second working platform has a second mounting slot. Rotary clamping components are fixedly installed in both the first and second mounting slots.

[0006] Preferably, the guide rail assembly includes a linear guide rail and a slide block. The linear guide rail is fixedly installed on both sides of the top surface of the mechanism tooling body, and the slide block is slidably installed on the linear guide rail. The top surface of the slide block is fixedly installed on both sides of the bottom surface of the first working platform.

[0007] Preferably, a stop block is installed on the top surface of the tooling body at both ends of the linear guide rail, and a limiter is installed on the inner side of the stop block.

[0008] Preferably, the drive assembly includes a drive motor, a gear, and a rack. The drive motor is fixedly mounted on the bottom surface of the first working platform, the gear is keyed to the shaft of the drive motor, and the rack is fixedly mounted on the inner side wall of the mechanism tooling body. The gear and the rack are meshed together.

[0009] Preferably, the rotary clamping assembly includes a rotary clamping cylinder, a rotary pressure plate, and a pressure rod. The rotary clamping cylinder is fixedly installed in the first mounting groove and the second mounting groove, respectively. One end of the rotary pressure plate is fixedly installed to the shaft of the rotary clamping cylinder, and the other end of the rotary pressure plate is fixedly installed to the pressure rod.

[0010] Preferably, pins are fixedly installed on both sides of the bottom surface of the support base, and pin holes are opened on both sides of the top surface of the first working platform, and the pins are inserted into the pin holes.

[0011] Preferably, handles are fixedly installed on both sides of the second working platform.

[0012] The beneficial effects of this application are: 1. This technical solution uses the pin on the bottom of the support base to precisely connect with the pin hole on the top of the first working platform, combined with the handle to achieve quick disassembly and installation. When different types of structural parts need to be processed, there is no need to adjust the overall structure of the mechanism. Only the replacement platform that is compatible with the new parts needs to be replaced. The part positioning block and rotating clamping component on the new platform can be directly adapted to the new parts. This effectively solves the problem of poor adaptability to multiple products and long changeover time caused by the fixed platform in traditional mechanisms. It allows the mechanism to flexibly meet the glue application needs of different specifications of parts, thereby improving production efficiency.

[0013] 2. This technical solution addresses two key issues. First, the positioning blocks on the first working platform and the replacement platform are precisely set according to the shape and size of the parts. Combined with the pressure rod driven by the rotary clamping cylinder in the rotary clamping assembly, this firmly clamps the parts, preventing them from shifting during platform movement or glue application, thus ensuring accurate glue application positioning. Second, the linear guide rail and slide block provide precise guidance for the first working platform. The drive motor, through gear and rack meshing, ensures smooth platform movement. Simultaneously, the stops and limiters at both ends of the linear guide rail provide double protection, preventing the platform from overtraveling and colliding. This solution solves the problems of unstable part positioning, insufficient platform movement accuracy, and lack of safety in traditional mechanisms, improving glue application quality while ensuring safe operation.

Detailed Implementation

[0017] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present application.

[0019] Please see Figure 1-4 The embodiments provided by this utility model are as follows: like Figure 1 and Figure 2 As shown, a novel automated glue-applying mechanism for automotive structural parts includes a mechanism fixture body 1. A first working platform 4 is slidably connected to the mechanism fixture body 1 via a guide rail assembly 2. The guide rail assembly 2 includes a linear guide rail 21 and a slide block 22. The linear guide rail 21 is fixedly installed on both sides of the top surface of the mechanism fixture body 1, and the slide block 22 is slidably installed on the linear guide rail 21. The top surface of the slide block 22 is fixedly installed on both sides of the bottom surface of the first working platform 4. The linear guide rail 21 is fixed on both sides of the top surface of the mechanism fixture body 1, providing a precise guide track for the slide block 22. The slide block 22 can reciprocate along the linear guide rail 21. Since the top surface of the slide block 22 is fixed to both sides of the bottom surface of the first working platform 4, when the slide block 22 slides, it will drive the first working platform 4 to move synchronously along the linear guide rail 21, thereby realizing the translation of the first working platform 4 on the mechanism fixture body 1, and transferring the parts through the first working platform 4 to the other side for robotic glue-applying operations. The first working platform 4 moves linearly on the top surface of the mechanism tooling body 1 via the drive assembly 5. The drive assembly 5 includes a drive motor 51, a gear 52 and a rack 53. The drive motor 51 is fixedly installed on the bottom surface of the first working platform 4. The gear 52 is keyed to the rotating shaft of the drive motor 51. The rack 53 is fixedly installed on the inner side wall of the mechanism tooling body 1. The gear 52 and the rack 53 are meshed together. When the drive motor 51 is working, its shaft will drive the gear 52 to rotate. The rotational motion of the gear 52 will be converted into the linear motion of the first working platform 4 along the linear guide rail 21. By controlling the forward and reverse rotation and speed of the drive motor 51, the reciprocating motion of the first working platform 4 and the adjustment of the motion speed can be realized. Furthermore, each of the two ends of the linear guide rail 21 has a stop 3 mounted on its top surface. Each stop 3 has a limiter 31 mounted on its inner side. When the first working platform 4 moves to the end of the linear guide rail 21, the stop 3 physically prevents the first working platform 4 from continuing to move, thus preventing it from detaching from the linear guide rail 21. The limiter 31 is mounted inside the stop 3. When the first working platform 4 approaches the end, the limiter 31 detects the platform's position and sends a signal to control the drive motor 51 to stop, preventing a violent collision between the first working platform 4 and the stop 3. like Figure 3 and Figure 4 As shown, a replacement platform 8 is detachably installed on the first working platform 4. The replacement platform 8 includes a support base 81 and a second working platform 83. Handles 84 are fixedly installed on both sides of the second working platform 83. The support base 81 is fixedly installed on both sides of the bottom surface of the second working platform 83. The support base 81 is inserted into the first working platform 4. The first working platform 4 and the replacement platform 8 are installed in a detachable manner, so that the replacement platform 8 can be easily removed from or installed on the first working platform 4. The handles 84 on both sides of the second working platform 83 facilitate the operator to move and replace the replacement platform 8. When different automotive structural parts need to be processed, the corresponding replacement platform 8 can be quickly replaced, realizing the rapid change of the mechanism and improving the adaptability of the mechanism to different automotive structural parts. Among them, pins 82 are fixedly installed on both sides of the bottom surface of the support base 81, and pin holes 42 are opened on both sides of the top surface of the first working platform 4. The pins 82 are inserted into the pin holes 42. The pins 82 on both sides of the bottom surface of the support base 81 and the pin holes 42 on both sides of the top surface of the first working platform 4 are matched in size. When the platform 8 is installed or replaced, the pins 82 are aligned with the pin holes 42 and inserted to achieve precise positioning and fixation of the support base 81 and the first working platform 4, ensuring that the position of the replaced platform 8 on the first working platform 4 is accurate. Multiple part positioning blocks 6 are fixedly installed on both the first working platform 4 and the second working platform 83. These blocks are designed according to the shape and size of the automotive structural parts and can position the parts to ensure that they are placed in the correct position. The first working platform 4 has a first mounting slot 41 and the second working platform 83 has a second mounting slot 85. Rotary clamping components 7 are fixedly installed in both the first mounting slot 41 and the second mounting slot 85. The first mounting slot 41 and the second mounting slot 85 provide mounting positions for the rotary clamping components 7, allowing them to be securely installed on the working platforms.

[0020] Specifically, such as Figure 2As shown, the rotary clamping assembly 7 includes a rotary clamping cylinder 71, a rotary pressure plate 72, and a pressure rod 73. The rotary clamping cylinder 71 is fixedly installed in the first mounting groove 41 and the second mounting groove 85, respectively. One end of the rotary pressure plate 72 is fixedly installed with the shaft of the rotary clamping cylinder 71, and the other end of the rotary pressure plate 72 is fixedly installed with the pressure rod 73. When it is necessary to clamp the part, the shaft of the rotary clamping cylinder 71 extends and rotates, driving the rotary pressure plate 72 to rotate, and then retracts, causing the pressure rod 73 to move downward and clamp the part. When it is necessary to release the part, the shaft of the rotary clamping cylinder 71 extends and rotates again, driving the rotary pressure plate 72 to rotate in the opposite direction, and the pressure rod 73 is lifted accordingly, releasing the clamping of the part, ensuring that the part will not move or shake during the glue application process, and ensuring the accuracy and quality of the glue application.

[0021] Working principle: The main body of the mechanism fixture 1 is fixed to the side of the glue-applying robot. The main body of the mechanism fixture serves as a basic support. The linear guide rails 21 on both sides of its top surface cooperate with the slide block 22 on the bottom surface of the first working platform 4 to provide precise guidance for the first working platform 4. When the drive motor 51 is running, it drives the first working platform 4 to make reciprocating linear motion along the linear guide rail 21 through the meshing transmission of gear 52 and rack 53, realizing the transfer of parts between the glue-applying position and the loading and unloading position. The stops 3 and limiters 31 at both ends of the linear guide rail 21 form a double protection to prevent the platform from overtravel or colliding. During operation, the automotive structural parts to be glued are placed on the first working platform 4 or the replacement platform 8, and are precisely positioned by the part positioning block 6 on the platform. Subsequently, the rotary clamping cylinder 71 drives the rotary pressure plate 72 and the pressure rod 73 to firmly clamp the parts, preventing them from moving during platform movement or glue application. When different types of structural parts need to be processed, the pin 82 on the bottom surface of the support base 81 and the pin hole 42 on the top surface of the first working platform 4 are precisely connected. The replacement platform 8 can be quickly disassembled and replaced with a new part by means of the handle 84. The replaced platform can achieve the positioning and fixing of the new part through its own positioning block and rotating clamping assembly 7. It can adapt to the glue application requirements of different parts without adjusting the overall structure of the mechanism.

[0022] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
