Description

Technical Field

[0001] This invention relates to the field of cushioning pad installation technology, and in particular to an automatic installation device for cover cushioning pads. Background Technology

[0002] As a crucial component of the car body, the quality of the connection and fit between the hood and the body directly impacts the vehicle's NVH performance and user experience. To cushion the rigid impact between the hood and the body panels when closed, and to adjust the surface difference between the hood and the fenders, cushioning pads (such as...) are typically installed at specific locations on the inner edge of the hood. Figure 6 (As shown).

[0003] Most existing buffer pads are made of rubber or thermoplastic elastomer materials. They utilize the elastic deformation characteristics of the material itself to achieve installation and locking. Their typical structure is conical or cylindrical, with a snap-fit ​​part at the bottom. During installation, the buffer pad is pressed into the pre-made boss inside the engine hood by external force. The boss is usually a hollow frustum structure with an opening on one side to accommodate the buffer pad.

[0004] Currently, the automated installation process for buffer pads generally adopts a push-rod method. The specific process is as follows: push rods are set at the corresponding boss positions on the installation platform, and the buffer pads are placed on each push rod in sequence by a mechanical device; after the buffer pads are in place, the robotic arm grabs the engine hood to the fixed platform and clamps it in position, while the pressure plate presses against the back of the corresponding buffer pad installation area on the outer panel of the engine hood as a force support; then, the push rods extend and push the buffer pads axially into the bosses of the engine hood, using the compression deformation and rebound characteristics of the rubber material to complete the snap-fit ​​locking.

[0005] However, the following problems exist in the current installation process of the buffer pad: 1. The boss structure is fragile and easily damaged. The boss has a hollow, open frustum structure, and its bottom area, where it connects to the inner panel of the engine hood, is the weakest point. Existing equipment uses a push rod to directly push the buffer pad, concentrating the axial thrust at the bottom of the boss. This causes the area to bear large bending stress, making it extremely prone to deformation or even cracking. Since the engine hood is expensive, such damage will cause significant economic losses and cannot be effectively avoided during installation.

[0006] 2. Rework and disassembly are highly destructive. When the installation of the buffer pad is found to be substandard or it needs to be replaced in subsequent repairs, the current common practice is to forcibly pry it out with tools such as pry bars. Due to the lack of a dedicated disassembly structure and force points, this method is very likely to cause the buffer pad to tear and leave behind fragments. More seriously, it may scratch the engine cover or damage the boss, turning a repairable defect into irreversible permanent damage, increasing rework costs and repair difficulty.

[0007] Therefore, the lack of guidance during installation, leading to cracks at the bottom of the boss due to stress, and the lack of a dedicated structure for rework and disassembly, resulting in severe secondary damage, are technical problems that need to be solved by those skilled in the art. Summary of the Invention

[0008] In view of the above problems, the present invention provides an automatic installation device for cover cushioning pads to solve the aforementioned technical problems.

[0009] To achieve the above objectives, the present invention provides the following technical solution: an automatic installation device for a cover buffer pad, comprising a device frame and a workbench fixedly installed thereon, a fixed seat fixedly installed on the workbench, and suction holes evenly opened at the upper end of the fixed seat; a plurality of bases are evenly installed at the upper end of the workbench, and an assembly mechanism is provided on the base.

[0010] The assembly mechanism includes a slide rod slidably mounted on a base, a suction cup fixedly installed at the upper end of the slide rod, a guide tube on the base with a tapered upper part, a drive unit on the base, and a lifting unit on the worktable.

[0011] The engine hood has a boss inside, and a limit hole is opened on the boss.

[0012] During installation, the suction cups adhere and fix the buffer pad. The drive unit drives the guide tube through the limiting hole of the boss, and the lifting unit drives the slide rod to move the suction cups and buffer pads towards the guide tube, so that the buffer pads are squeezed and contained within the guide tube. The installation thrust is borne by the guide tube. Subsequently, the drive unit drives the guide tube to move in the opposite direction to reset, and the buffer pads move to the installation position and then detach from the guide tube. The buffer pads regain their elasticity and are locked within the boss. During disassembly, the suction cups adhere and fix the buffer pads, and the drive unit drives the guide tube to squeeze the buffer pads and contain them within the guide tube. The guide tube then moves the buffer pads to detach from the boss without damage.

[0013] As a preferred embodiment, the lifting unit includes a connecting plate. The lower end of the slide rod slides through the base and the worktable and is fixedly installed on the connecting plate. A cylinder is fixedly installed at the lower end of the worktable through a fixing frame. The telescopic section of the cylinder slides through the fixing frame and is fixedly connected to the lower end of the connecting plate.

[0014] As a preferred embodiment, the drive unit includes a support plate, the base has an L-shaped structure, the support plate is slidably installed on the upper end of the horizontal section of the base, a second cylinder is fixedly installed on the support plate, a fixing plate is fixedly installed on the telescopic section of the second cylinder, and the fixing plate is fixedly connected to the guide tube.

[0015] As a preferred embodiment, a cylinder three is fixedly installed at the upper end of the vertical section of the base, and the telescopic section of the cylinder three is fixedly connected to the support plate.

[0016] As a preferred embodiment, the upper end of the guide tube is connected to an air pipe connector.

[0017] As a preferred embodiment, a limiting ball is fixedly installed at the middle of the upper end of the suction cup.

[0018] As a preferred embodiment, the guide tube port is rounded.

[0019] The above-described one or more technical solutions in the embodiments of the present invention have at least one of the following technical effects: First, the present invention achieves automated installation and removal of the buffer pad through the coordinated operation of the guide tube, suction cup, drive unit, and lifting unit. During installation, after the guide tube passes through the boss limiting hole, the buffer pad is squeezed and contained within the guide tube, and the installation thrust is borne by the guide tube, effectively avoiding the problem of the boss bottom breaking under stress. During removal, the suction cup adsorbs and fixes the buffer pad, and the guide tube squeezes and contains it, driving it to detach from the boss, achieving non-destructive removal. This protects the engine hood body from damage and solves the problem of highly destructive rework disassembly.

[0020] Second, the present invention uses a guide tube to pass through the limiting hole of the boss to bear the installation thrust, so that the axial force generated by the buffer pad during the installation process is borne by the guide tube instead of being directly applied to the weak area at the bottom of the boss. This solves the problem that the boss is easily damaged due to the concentration of force at the bottom in the prior art, and significantly reduces the scrap risk and production cost of the engine hood.

[0021] Third, this invention achieves non-destructive disassembly of the buffer pad through the cooperation of a suction cup and a guide tube. During disassembly, the suction cup first adsorbs and fixes the buffer pad to form a reliable limit and resistance. The guide tube squeezes and contains the buffer pad inside the tube. Then, the guide tube drives the buffer pad to move, so that it can be smoothly removed from the boss. The whole process does not require the use of prying tools or other tools to forcibly pry it out, which completely avoids problems such as tearing of the buffer pad, fragment residue, scratches on the paint surface, and secondary damage to the boss. It provides a safe and reliable standardized operating method for rework and repair.

Detailed Implementation

[0031] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, an automatic installation device for a cover buffer pad includes a device frame 10 and a workbench 11 fixedly installed thereon. A fixed seat 12 is fixedly installed on the workbench 11, and suction holes are evenly opened on the upper end of the fixed seat 12. A plurality of bases 13 are evenly installed on the upper end of the workbench 11, and an assembly mechanism 2 is provided on the base 13.

[0033] like Figure 2 , Figure 3 and Figure 4 As shown, the assembly mechanism 2 includes a slide rod 20 slidably disposed on the base 13, a suction cup 21 fixedly installed on the upper end of the slide rod 20, a guide tube 22 disposed on the base 13, the upper part of the guide tube 22 having a conical structure, a drive unit 4 disposed on the base 13, and a lifting unit 3 disposed on the worktable.

[0034] A boss 5 is provided inside the engine hood, and a limit hole 6 is correspondingly provided on the boss 5.

[0035] like Figure 4 and Figure 5 As shown, a limiting ball 210 is fixedly installed at the middle of the upper end of the suction cup 21.

[0036] like Figure 4 and Figure 5 As shown, the port of the guide tube 22 is rounded.

[0037] like Figures 1 to 6 As shown, during the actual operation, the external robotic arm first places the buffer pads onto the corresponding suction cups 21 in sequence. The suction cups 21 use vacuum to adsorb and fix the buffer pads to be installed onto them. The limiting ball 210 is embedded in the center hole of the buffer pad to ensure that the buffer pad and the suction cup 21 are coaxially positioned. Then, the external robotic arm places the engine cover on the worktable 11. The adsorption holes on the fixing seat 12 use vacuum to adsorb and fix the engine cover.

[0038] The drive unit 4 drives the guide tube 22 to move towards the engine hood, so that the guide tube 22 moves into the boss on the engine hood and aligns with the limiting hole of the boss. The drive unit 4 continues to drive the guide tube 22 to move downward, so that the guide tube 22 passes through the limiting hole of the boss and the lower end of the guide tube 22 extends out to the bottom of the boss.

[0039] The lifting unit 3 drives the slide bar 20 to move upward. The slide bar 20 drives the suction cup 21 and the buffer pad attached to it to rise together. During the rise, the buffer pad first contacts the lower end of the guide tube 22. The rounded corner treatment at the end of the end makes the buffer pad smoothly transition when it contacts the guide tube 22, avoiding sharp edges from scratching the surface of the buffer pad. At the same time, it guides the buffer pad to smoothly enter the guide tube 22 without getting stuck. As the suction cup 21 continues to rise, the buffer pad gradually enters the tube under the guidance of the port of the guide tube 22. When the buffer pad enters the guide tube 22, it undergoes elastic deformation and is compressed and contained in the guide tube 22. The suction cup 21 continues to rise until the part of the buffer pad pressed into the boss is completely inside the guide tube 22.

[0040] The drive unit 4 drives the guide tube 22 to move upward and reset. The guide tube 22, carrying the buffer pad inside, moves upward together with the slide rod 20 and the suction cup 21. When the guide tube 22 moves upward into the boss, the suction cup 21 remains stationary, and the guide tube 22 continues to move upward, causing the buffer pad to disengage from the guide tube 22. Due to the loss of the constraint of the guide tube 22, the buffer pad restores its shape under its own elasticity, and its locking part expands outward and fits tightly against the inner wall of the boss limiting hole, forming a reliable lock.

[0041] When it is necessary to remove the installed buffer pad, the suction cup 21 first adheres to the buffer pad to fix it in place and prevent it from shifting during the removal process. Then, the drive unit 4 drives the guide tube 22 to move into the boss on the engine hood and moves the guide tube 22 downward to squeeze the conical part of the buffer pad into the guide tube 22. Then, the guide tube 22 continues to move downward to bring the buffer pad inside out of the mounting boss. After that, the guide tube 22 remains stationary, and the suction cup 21 moves to remove the buffer pad from the guide tube 22. Then, the above operation is performed to replace the new buffer pad.

[0042] like Figure 2 and Figure 3 As shown, the lifting part 3 includes a connecting plate 30. The lower end of the slide rod 20 slides through the base 13 and the worktable 11 and is fixedly installed on the connecting plate 30. The lower end of the worktable 11 is fixedly installed with a cylinder 31 through a fixing frame. The telescopic section of the cylinder 31 slides through the fixing frame and is fixedly connected to the lower end of the connecting plate 30.

[0043] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the drive unit 4 includes a support plate 40, the base 13 has an L-shaped structure, the support plate 40 is slidably installed on the upper end of the horizontal section of the base 13, a second cylinder 41 is fixedly installed on the support plate 40, a fixing plate 42 is fixedly installed on the telescopic section of the second cylinder 41, and the fixing plate 42 is fixedly connected to the guide tube 22.

[0044] like Figure 3 and Figure 4 As shown, a cylinder 43 is fixedly installed on the upper end of the vertical section of the base 13, and the telescopic section of the cylinder 43 is fixedly connected to the support plate 40.

[0045] like Figure 4 and Figure 5 As shown, the upper end of the guide tube 22 is connected to an air pipe connector 220.

[0046] like Figures 1 to 6 As shown, during actual operation, cylinder 3 43 starts, driving support plate 40 to slide along the horizontal section of base 13, moving support plate 40 to the working position. At this time, guide tube 22 is located inside the boss and aligned with the limiting hole of the mounting boss. Cylinder 2 41 then starts, driving fixing plate 42 and guide tube 22 fixedly connected to fixing plate 42 to move towards the engine hood, so that the lower end of guide tube 22 moves to below the boss on the engine hood.

[0047] When cylinder 31 is activated, it drives connecting plate 30 to move upward. Connecting plate 30 drives slide rod 20, which is fixedly connected to it, to rise synchronously. Slide rod 20 drives suction cup 21 and the buffer pad adsorbed on it to rise together, so that the conical part of the buffer pad is squeezed into guide tube 22. During this process, air pipe connector 220 sucks air into guide tube 22, forming a negative pressure inside guide tube 22. This negative pressure acts on the buffer pad, generating an inward adsorption and traction force on the buffer pad that is being squeezed in, and assisting guide tube 22 in compressing and containing the buffer pad.

[0048] After the buffer pad moves into place with the guide tube 22, the movement of the guide tube 22 causes the buffer pad to gradually detach from the guide tube 22. At this time, air is blown into the guide tube 22 through the air pipe connector 220. Compressed air is blown out from the lower end of the guide tube 22, forming an auxiliary thrust at the moment the buffer pad detaches from the guide tube 22, helping the buffer pad to quickly separate from the guide tube 22 and be clamped onto the boss.
