Description

Technical Field

[0001] The utility model relates to the field of automobile carpet manufacturing, in particular to an automobile carpet forming device for automatically pre-embedded carpet accessories. Background Art

[0002] Finished automotive carpets include a main body and carpet accessories (such as floor mats). Manufacturing automotive carpets requires a pressing device (also known as an automotive carpet forming device). The pressing device comprises two mold bases, upper and lower. The upper mold base has an upper mold mounted in the center of its bottom wall, with multiple positioning posts installed around its perimeter. The lower mold base has a plurality of vertical sleeves mounted around its top wall, equal in number to the positioning posts. A lower mold is mounted in the center of its top wall, with a pre-embedded groove defined in its top wall. The manufacturing process for the finished automotive carpet is as follows: an operator manually places the carpet accessories into the pre-embedded grooves to embed them. The main body of the automotive carpet is then placed on the lower mold, covering the carpet accessories. The pressing device is activated, causing the upper mold to move downward, driving the multiple positioning posts downward and inserting them into the multiple vertical sleeves. These vertical sleeves, guided by the corresponding positioning posts, align the upper mold with the lower mold. The upper mold then moves downward, pressing the carpet body and carpet accessories onto the lower mold to form them. A drawback of the prior art is that both the pre-embedded carpet accessories and the placement of the main body require manual labor, which is labor-intensive for the operator. Utility Model Content

[0003] The inventors have secretly developed an automotive carpet forming device comprising a robotic arm and first and second conveyor belts. The first conveyor belt delivers multiple automotive carpet bodies to the robotic arm one by one, while the second conveyor belt delivers multiple carpet accessories to the robotic arm one by one. The robotic arm, replacing manual operation, picks up a carpet accessory from the second conveyor belt and places it into the pre-embedded groove for pre-embedded operation. It then picks up a carpet body from the first conveyor belt and places it on the lower mold, covering the carpet accessory. A pressing device automatically activates, causing the upper mold to press downward. While this automotive carpet forming device is automated, eliminating manual operation for both the pre-embedded carpet accessory and the placement of the automotive carpet body, the need for the first and second conveyor belts necessitates a large footprint.

[0004] The utility model aims to provide an automobile carpet forming device for automatically pre-embedding carpet accessories. The automobile carpet forming device not only eliminates the need for manual operation in the two steps of pre-embedding carpet accessories and placing the automobile carpet body, but also only requires one conveyor belt to reduce floor space.

[0005] An automotive carpet forming device for automatically pre-embedded carpet accessories comprises upper and lower die bases. An upper die is mounted in the center of the bottom wall of the upper die base, and a plurality of positioning posts are mounted on the periphery of the bottom wall. A plurality of vertical sleeves are mounted on the periphery of the top wall of the lower die base, and a lower die is mounted in the center of the top wall. A pre-embedded groove is formed on the top wall of the lower die base. The lower portion of the circumferential side wall of one vertical sleeve protrudes outward to form a limit block, which is used to fit the notches of a plurality of concave-shaped carpet accessories stacked vertically. A downward-facing suction cup is mounted on the side of the positioning post directly above the vertical sleeve, and the suction cup is mounted on the periphery of the bottom wall of the upper die base. A universal manipulator is mounted on the side wall of the upper die base.

[0006] The upper mold base moves downward, driving the upper mold, positioning posts, suction cups, and universal manipulator downward. The positioning posts move downward until they are inserted into multiple vertical sleeves, guiding the upper mold to fine-tune its alignment with the lower mold. The upper mold moves downward until it is pressed onto the lower mold, and the suction cups move downward until they contact the topmost carpet attachment and hold it in place.

[0007] When the upper mold has been moved up and reset, the universal robot grabs the carpet accessory on the suction cup that has been moved up and reset and then sends it to the embedded groove of the lower mold; the conveyor belt is included, and the conveyor belt sends multiple car carpet bodies one by one to the universal robot. The universal robot places the car carpet body at the front of the conveyor belt on the lower mold to cover the carpet accessory.

[0008] Furthermore, a vertical cylinder is provided on the side of the positioning column just above the limit block. The vertical cylinder is mounted on the peripheral edge of the bottom wall of the upper mold, and the vertical cylinder can extend a driving rod downward; the suction cup is mounted on the bottom of the driving rod.

[0009] Furthermore, a space of 5 cm is left between the limiting block and the lower mold.

[0010] Furthermore, the universal manipulator comprises two gripping fingers, which are horizontally arranged side by side up and down.

[0011] Furthermore, the number of the vertical sleeves and the positioning columns are the same and their positions correspond to each other.

[0012] The beneficial effect is that after multiple concave-shaped carpet accessories are stacked, they are encased in a stop block through their notches. They are restrained front and rear by the stop block's front sidewall and the lower mold's rear sidewall, and left and right by the stop block's left and right sides, preventing them from accidentally falling off the stop block. The downward movement of the upper mold base not only drives the upper mold downward to lower and form a car carpet body and a carpet accessory on the lower mold, but also drives the suction cup downward, allowing it to absorb the next carpet accessory. The upper mold then moves upward and resets, and the suction cup moves upward with the next carpet accessory. The universal manipulator removes the finished car carpet from the lower mold, then grabs the carpet accessory from the suction cup and places it into a pre-embedded groove in the lower mold for pre-embedding. The front car carpet body on the conveyor belt is then placed on the lower mold, covering the carpet accessory. The lower mold base can then move downward again, simultaneously completing the pressing and removing of a new carpet accessory. In summary, the automobile carpet forming device of the present invention does not require manual operation for the two steps of pre-embedding carpet accessories and placing the automobile carpet body, and only requires one conveyor belt, without the need for a special conveyor belt for transporting carpet accessories, thereby reducing the floor space.

[0015] The present invention will be further described in detail below in conjunction with specific implementation methods.

[0016] like Figure 1As shown, an automotive carpet molding device for automatically pre-embedded carpet attachments 12 includes a lower mold base 7, with multiple vertical sleeves 9 mounted along the perimeter of the top wall of the lower mold base 7 and a lower mold 8 mounted in the center of the top wall. A concave-shaped pre-embedded groove (not shown) is defined in the top wall of the lower mold 8. The lower portions of the circumferential sidewalls of these vertical sleeves 9 protrude outward to form stoppers 11, with a 5 cm gap 13 between the stoppers 11 and the lower mold 8. Multiple concave-shaped carpet attachments 12 are stacked on the perimeter of the top wall of the lower mold base 7 and the gap 13, with their notches encasing a stopper 11 at the right rear. The carpet attachments 12 are restrained forward and backward by both the front sidewall of the stopper 11 and the rear sidewall of the lower mold 8, and left and right by the left and right sidewalls of the stopper 11, preventing them from accidentally falling off the stopper 11. An upper die base 1 is located directly above the lower die base 7. The upper die 2 is mounted in the center of the bottom wall of the upper die base 1. Multiple positioning posts 3 are installed around the perimeter of the bottom wall. The number of positioning posts 3 matches the number of vertical sleeves 9, and their positions correspond. A vertical cylinder 5 is located to the left of the right rear positioning post 3. The vertical cylinder 5 is mounted on the perimeter of the bottom wall of the upper die 2. The vertical cylinder 5 can extend a drive rod downward, and a suction cup 6 is installed on the bottom wall of the drive rod. A universal manipulator 4 is installed on the right side wall of the upper die base 1. The universal manipulator 4 includes two horizontal gripping fingers, which are arranged side by side. A front-to-back horizontal conveyor belt (not shown) is installed behind the universal manipulator 4. The conveyor belt transports multiple car carpet bodies to the universal manipulator 4 one by one.

[0017] The following details the operation process. The upper mold base 1 moves downward, driving the upper mold 2, positioning posts 3, suction cups 6, and universal manipulator 4 downward. The positioning posts 3 move downward until they are inserted into multiple vertical sleeves 9, guiding the upper mold 2 for fine-tuning of its lateral alignment with the lower mold 8. The upper mold 2 moves downward until it is pressed against the lower mold 8. The suction cups 6 move downward until they contact and secure the topmost carpet attachment 12. The upper mold base 1 then resets, driving this carpet attachment 12 upward and away from the other stacked carpet attachments 12. The universal manipulator 4 uses two gripping fingers to grasp this carpet attachment 12 and transport it to a pre-buried groove in the lower mold 8 for embedment. The gripping fingers then place the frontmost automotive carpet body on the lower mold 8, covering the carpet attachment 12, before resetting. The upper die base 1 moves downward again, allowing the upper die 2 to press and form the carpet attachments 12 and the main body of the car carpet. Simultaneously, the suction cup 6 descends onto the stacked carpet attachments 12, securing the topmost one. In other words, the single downward movement of the upper die base 1 both drives the upper die 2 to complete the current press and the suction cup 6 to retrieve the carpet attachment 12 needed for the next press. This eliminates the need for a dedicated conveyor belt to transport the carpet attachments 12, thus reducing floor space. By repeating these steps, multiple finished car carpets can be pressed one by one.

[0018] Preferably, the upper mold base 1 is further provided with a controller connected to the vertical cylinder 5. The controller records the number of times the mold 8 is pressed downward and controls the vertical cylinder 5 to extend downward according to the number of times the mold 8 is pressed downward, thereby adjusting the height of the suction cup 6 to fit the stacked carpet accessory 12, ensuring that the suction cup 6 can contact the stacked carpet accessory 12 each time it moves downward.

[0019] The above is only an embodiment of the present invention and does not limit the scope of patent protection. Those skilled in the art can make non-substantial changes or substitutions based on the present invention and still fall within the scope of patent protection.
