Description

Technical Field

[0001] The utility model relates to the technical field of foam trimming, and particularly relates to a seat foam trimming device. Background Art

[0002] Seat foam is a key component for seat comfort and support. It is usually made of polyurethane (PU) material and produced through a foaming process, which can provide good cushioning effect and resilience. Before actual automotive seat assembly work, after the seat foam is foamed and formed, there are more or less irregular problems such as burrs on the seat foam. In order to ensure the effect after seat foam assembly, it is often necessary to remove the excess scraps to make its shape more precise for subsequent covering and assembly.

[0003] In the Chinese patent with the application number 202320656223.8, a trimming device for automotive seat foam is disclosed. In the disclosed trimming device, it is described that "by using the set integral cutting part in cooperation with the installation support part, auxiliary integral cutting and trimming can be realized, ensuring the overall trimming efficiency. At the same time, by using the set integral cutting upper die in cooperation with the lower die shell, the foam pad can be embedded, and auxiliary precise positioning can be realized, ensuring the cutting quality". Although this trimming device can ensure the trimming quality, the debris generated during trimming will remain in the sunken foam installation groove, which is not convenient for quick cleaning and mostly requires manual cleaning and collection from the foam installation groove, being rather troublesome and time-consuming.

Detailed Embodiment

[0032] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail with reference to the drawings.

[0033] Figure 1 and Figure 2These are schematic diagrams of the overall structure of the present utility model. As shown in the figure, the seat foam trimming device includes a workbench 1, two movable baffles 5, and a material receiving assembly 6. A cavity is recessed in the front side of the workbench 1. A PLC controller is installed on the side wall of the workbench 1, and a robotic arm 2 is installed near the rear side of the upper end surface of the workbench 1. A laser cutter 3 is installed at the end of the robotic arm 2. Waste holes 9 are opened at both ends of the upper end surface of the workbench 1. One movable baffle 5 penetrates through one waste hole 9. A telescopic member is provided inside the workbench 1, and the two movable baffles 5 are synchronously lifted and lowered by the telescopic member. After the two movable baffles 5 are lifted, the area between the two movable baffles 5 is the placement area for the foam to be trimmed. An arc-shaped guide surface 13 is integrally formed at the top of each of the two movable baffles 5. The arc-shaped guide surface 13 is provided to facilitate the sliding down of the trimming debris and reduce the occurrence of adhesion to the top of the movable baffle 5. The material receiving assembly 6 is provided at both ends inside the workbench 1, and the material receiving assembly 6 includes a material receiving part and a discharging part. The discharging part is detachably installed on the material receiving part.

[0034] Among them, referring to Figure 3 as shown, the telescopic member includes:

[0035] An electric telescopic rod 4, which is installed at the middle inside of the workbench 1;

[0036] A support plate 11, which is fixed to the top of the electric telescopic rod 4;

[0037] Two brackets 12, which are symmetrically fixed at both ends of the support plate 11, and the movable baffle 5 is fixed to the upper end surface of the bracket 12.

[0038] In the specific implementation manner of the present utility model, referring to Figure 1 and Figure 4 as shown, the material receiving part is a material receiving frame 61, and the top and front side of the material receiving frame 61 are open;

[0039] The discharging part includes a slot 62, a pulling plate 63, and a pulling bar 64. The slot 62 is opened along the length direction at the bottom inside the material receiving frame 61. The rear end of the pulling bar 64 is connected to the bottom end of the pulling plate 63, and the pulling bar 64 is inserted and matched with the slot 62.

[0040] A grip plate 65 is fixed to the front end of the pulling bar 64, and the length of the grip plate 65 is greater than the width of the slot 62.

[0041] Through the above technical solutions:

[0042] During specific use, the electric telescopic rod 4 can be started first to raise the supporting plate 11, so that the tops of the two movable baffles 5 on the bracket 12 rise above the upper end surface of the workbench 1. Then, the seat foam to be trimmed is placed between the two movable baffles 5. Subsequently, the mechanical arm 2 and the laser cutting machine 3 can be controlled by the plc controller to start, and the trimming of the seat foam can be completed by the laser cutting machine 3 according to the preset path.

[0043] After the trimming of the seat foam is completed, the electric telescopic rod 4 can be used to lower the tops of the movable baffles 5 below the upper end surface of the workbench 1. Then, the debris generated by trimming on the workbench 1 is cleaned, and the debris falls from the waste leakage hole 9 into the material receiving frame 61. After a certain amount of debris is collected in the material receiving frame 61, the handle plate 65 can be held by hand and pulled outwards. By using the pull bar 64 to pull the pull plate 63 forward, the debris in the material receiving frame 61 can be pulled out and collected at one time, which is more convenient and practical.

[0044] In addition, referring to Figure 1 As shown, a scraping plate 7 is also provided above the workbench 1. The scraping plate 7 can move along the length direction of the workbench 1 through a sliding structure. A handle can be installed at the top of the scraping plate 7 for easy hand-held application of force.

[0045] Referring to Figure 1 and Figure 5 As shown, the sliding structure includes:

[0046] A fixed baffle 10, which is fixed to the rear side of the upper end surface of the workbench 1. Chute 8 is provided on the front surface of the fixed baffle 10 and the front upper side of the workbench 1;

[0047] A convex block 71, which is fixed to the front end of the scraping plate 7, and the lower end of the convex block 71 extends to the front upper side of the workbench 1. Sliders 14 are fixed to both the convex block 71 and the rear end of the scraping plate 7, and the sliders 14 are slidably engaged with the chute 8.

[0048] Through the above, when it is necessary to clean the debris above the workbench 1, first lower the movable baffle 5, and then the staff can move the scraping plate 7. By using the linear sliding of the slider 14 in the chute 8, the scraping plate 7 can be moved orderly to send the debris above the workbench 1 to the waste leakage hole 9 to fall, without the need to take out the cleaning equipment, which is more convenient.

[0049] In addition, an automatic driving structure (which can be a cylinder or a telescopic rod) can be set to connect the scraping plate 7. At this time, when cleaning the debris above the workbench 1, automatic scraping and sending can be realized, which is more convenient.

[0050] Only some exemplary embodiments of the present utility model have been described by way of illustration. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present utility model. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present utility model.
