Description

Technical Field

[0001] This invention relates to the field of rubber sealing strip manufacturing technology, and in particular to a feeding device for an automotive rubber sealing strip adhesive system. Background Technology

[0002] In the production of automotive rubber sealing strips, adhesive is required for the rubber strips. Adhesive backing involves attaching a strip of tape to the rubber strip, so that during subsequent installation, the protective layer on the tape can be peeled off, making it easy to install the rubber sealing strip onto the corresponding sealing parts such as car doors and windows.

[0003] For semi-rectangular automotive rubber sealing strips, during the adhesive application process, they need to be placed in a corresponding groove on the platform to ensure stability during the adhesive application. However, because automotive rubber sealing strips are flexible, quickly inserting them into the groove is not an easy task. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a feeding device for a semi-automatic adhesive backing system for automotive rubber sealing strips, so as to solve the technical problem that it is time-consuming to manually place the automotive rubber sealing strips into the limiting grooves on the platform plate during the adhesive backing process, which affects the efficiency of the adhesive backing operation of automotive rubber sealing strips.

[0005] The present invention relates to a semi-automatic adhesive backing system for automotive rubber sealing strips, which includes a workbench. The workbench includes a platform plate and a support for supporting the platform plate. The platform plate is provided with an inner limiting strip and an outer limiting strip. A semi-rectangular rubber strip limiting groove that defines the position of the automotive rubber sealing strip is formed between the inner limiting strip and the outer limiting strip. The feeding device of the semi-automatic adhesive backing system for automotive rubber sealing strips of the present invention also includes a belt conveyor mechanism, an end clamping mechanism, and a straightening mechanism.

[0006] The belt conveyor mechanism includes a synchronous belt located above the platform plate, an active synchronous pulley that cooperates with the synchronous belt and is driven by a stepper motor, a driven synchronous pulley that is set on the platform plate and cooperates with the synchronous belt, and a support rail that is set on the platform plate and arranged along the rubber strip limiting groove. The support rail is provided with a vertical limiting groove that cooperates with the synchronous belt.

[0007] The end clamping mechanism includes a connecting plate fixed on a timing belt, a cylinder vertically mounted on the connecting plate with its piston rod facing downward, a pressure plate mounted on the end of the cylinder piston rod, and an L-shaped bearing plate mounted on the lower end of the connecting plate and cooperating with the pressure plate. The pressure plate and the bearing plate constitute a clamp for clamping the end of the automotive rubber sealing strip. The upper end of the connecting plate is provided with a roller that rolls along the top surface of the support rail.

[0008] The straightening mechanism includes a vertical shaft that is set on the outer limiting strip and evenly arranged along the rubber strip limiting groove, a paddle set on the upper end of the vertical shaft for straightening the automotive rubber sealing strip, and a spring mechanism for driving the vertical shaft to return the paddle to its original position. The paddle is perpendicular to the rubber strip limiting groove in its natural state.

[0009] Furthermore, the spring mechanism includes a spring bar that passes radially through the lower end of the vertical shaft and a cylinder disposed on the bottom surface of the outer limit bar to prevent the spring bar from rotating. The platform plate is provided with a clearance hole for the clearance spring mechanism.

[0010] The beneficial effects of this invention are:

[0011] This invention relates to a semi-automatic adhesive backing system for automotive rubber sealing strips, which uses an end-clamping mechanism to hold one end of the automotive rubber sealing strip and pull it into a rubber strip retaining groove.

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] As shown in the figure, the feeding device of the semi-automatic adhesive backing system for automotive rubber sealing strips in this embodiment includes a workbench. The workbench includes a platform plate 1 and a support 2 for supporting the platform plate. The platform plate is provided with an inner limiting strip 3 and an outer limiting strip 4. A semi-rectangular rubber strip limiting groove 5 that limits the position of the automotive rubber sealing strip is formed between the inner limiting strip and the outer limiting strip. The feeding device of the semi-automatic adhesive backing system for automotive rubber sealing strips in this embodiment also includes a belt conveyor mechanism, an end clamping mechanism, and a straightening mechanism.

[0018] The belt conveyor mechanism includes a synchronous belt 6 located above the platform plate, an active synchronous pulley 8 that cooperates with the synchronous belt and is driven by a stepper motor 7, a driven synchronous pulley 9 mounted on the platform plate that cooperates with the synchronous belt, and a support rail 10 mounted on the platform plate and arranged along a rubber strip limiting groove. The support rail has a vertical limiting groove that cooperates with the synchronous belt, which limits the synchronous belt's vertical position and ensures its stability. In this embodiment, a stepper motor drives the synchronous belt, enabling precise control of the conveying distance of the belt conveyor mechanism.

[0019] The end clamping mechanism includes a connecting plate 11 fixed to the timing belt, a cylinder 12 vertically mounted on the connecting plate with its piston rod pointing downwards, a pressure plate 13 mounted on the end of the cylinder piston rod, and an L-shaped bearing plate 14 mounted on the lower end of the connecting plate and cooperating with the pressure plate. The pressure plate and the bearing plate form a clamp for holding the end of the automotive rubber sealing strip. A roller 15 that rolls along the top surface of the support rail is provided at the upper end of the connecting plate. The weight of the end clamping mechanism is pressed onto the support rail by the roller, thereby avoiding the timing belt bearing the weight of the end clamping mechanism and ensuring the stability of the timing belt's vertical position.

[0020] The straightening mechanism includes a vertical shaft 16 disposed on the outer limiting strip and evenly arranged along the rubber strip limiting groove, a paddle 17 disposed at the upper end of the vertical shaft for straightening the automotive rubber sealing strip, and a spring mechanism for driving the vertical shaft to return the paddle to its original position. The paddle is perpendicular to the rubber strip limiting groove in its natural state.

[0021] In this embodiment, the spring mechanism includes a spring bar 18 that passes radially through the lower end of the vertical shaft and a cylinder 19 disposed on the bottom surface of the outer limiting bar to prevent the spring bar from rotating. The platform plate 1 is provided with a clearance hole to avoid the spring mechanism. Of course, in different embodiments, the spring mechanism may also take other forms.

[0022] In this embodiment, the feeding device of the semi-automatic adhesive backing system for automotive rubber sealing strips operates by first manually placing the end of the automotive rubber sealing strip into the clamp between the pressure plate and the bearing plate. Then, the piston rod of the cylinder is moved downward by a control switch or controller, clamping the end of the automotive rubber sealing strip in the clamp formed by the pressure plate and the bearing plate. Next, the stepper motor controller drives the active synchronous pulley to rotate, which in turn drives the synchronous belt to move, thereby moving the end clamping mechanism on it. As the end clamping mechanism moves along the rubber strip limiting groove, it pulls the automotive rubber sealing strip into the groove. During this movement, the end clamping mechanism pushes open the straightening mechanism's paddle. After the clamp disengages from the paddle, the spring bar 18 of the spring mechanism drives the paddle to reset. During the reset process, the paddle straightens and limits the automotive rubber sealing strip, ensuring it remains flat within the rubber strip limiting groove and preventing twisting. The feeding device used in this embodiment can improve the efficiency of installing automotive rubber sealing strips into the rubber strip limiting groove.

[0023] During the adhesive backing process, such as Figure 1 As shown, when the pusher 20 on the side of the pressure head of the adhesive backing mechanism 19 moves along the rubber strip limiting groove, it will also push open the straightening mechanism's paddle. The straightening mechanism will not affect the operation of the adhesive backing mechanism. After adhesive backing is completed, the rubber strip can be pulled out, or a discharge groove and discharge mechanism can be set on the platform plate 1 to allow the automotive rubber sealing strip to be discharged from below the platform plate.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
