[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This utility model provides a surface adhesive spraying device for automotive plastic parts. The plastic parts to be sprayed are placed in a spraying tank. A vacuum pump is activated, creating negative pressure in the suction cups to adhere the plastic parts to the tank. A rodless cylinder moves back and forth, driving multiple spray heads on the lower side of a connecting plate to spray adhesive evenly onto the top of the plastic parts. Excess water-based adhesive drips into a collection tank for recycling into a storage tank, preventing waste.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3This application proposes an embodiment of an automotive plastic parts surface spraying device. The device includes a spraying box 1, which is the main working area of ​​the entire device. The top opening is used to place the automotive plastic parts to be sprayed. A suction cup 2 is provided in the middle of the spraying box 1. A vacuum pump 3 is connected to the bottom of the suction cup 2. By starting the vacuum pump 3, the suction cup 2 generates negative pressure, adsorbing the plastic parts into the spraying box 1, ensuring that they remain stable during the spraying process.

[0019] A rodless cylinder 4 is horizontally mounted on both the front and rear sides of the opening of the spray box 1. A connecting plate 5 is horizontally mounted between the two rodless cylinders 4. Multiple glue spraying heads 6 are evenly mounted on the lower side of the connecting plate 5 for spraying glue onto the plastic parts. The rodless cylinders 4 allow the connecting plate 5 to move back and forth along the front and rear direction of the spray box 1, thereby driving the multiple glue spraying heads 6 to spray glue evenly onto the top of the plastic parts. The synchronous movement of the two rodless cylinders 4 to drive the movement of the connecting plate 5 is a conventional technique in the prior art and will not be described in detail here. A support frame 7 is provided at the bottom of the spray box 1. A glue storage tank 8 with an upper opening is provided in the middle of the support frame 7 corresponding to the spray box 1. Multiple liquid outlets 9 are evenly opened at the bottom of the spray box 1 for dripping excess water-based glue into the collection tank 13 for recycling.

[0020] To further optimize the glue recycling function, a conical platform 12 is provided around the vacuum pump 3 inside the spray box 1. The bottom periphery of the conical platform 12 and the side wall of the spray box 1 form a liquid collection tank 13 with a conical longitudinal section. Multiple liquid outlets 9 are evenly distributed at the bottom of the liquid collection tank 13, so that excess water-based glue can drip smoothly into the liquid collection tank 13 and flow back to the glue storage tank 8 through the liquid outlets 9, avoiding waste.

[0021] The support frame 7 is equipped with a gear pump 10 on its side wall. The inlet end of the gear pump 10 is connected to the bottom of the glue storage tank 8, and the outlet end is connected to multiple glue spraying heads 6 at the bottom of the connecting plate 5 through the outlet pipe 11. The function of the gear pump 10 is to transport the water-based glue in the glue storage tank 8 to the glue spraying heads 6 through the outlet pipe 11, so as to realize the recycling of glue.

[0022] To ensure the purity and recycling efficiency of the water-based adhesive, a filter screen 16 is horizontally inserted near the top of the adhesive storage tank 8. One end of the filter screen 16 passes through the side wall of the adhesive storage tank 8 and extends to the outside, with a handle 17 at the end. Using the handle 17, operators can easily pull the filter screen 16 out of or push it into the adhesive storage tank 8, facilitating cleaning and replacement. The function of the filter screen 16 is to filter impurities in the water-based adhesive, ensuring the purity of the adhesive and thus improving the quality of the sprayed adhesive. This filter screen 16 can be replaced with other filtration equipment, and is not limited to this.

[0023] To improve the flexibility and ease of operation of the equipment, a multi-section electric push rod 14 is provided between the vacuum pump 3 and the suction cup 2. The multi-section electric push rod 14 can adjust the height of the suction cup 2 as needed, thereby raising the plastic parts after glue spraying, making it easier for workers to pick them up and improving work efficiency. In addition, multiple glue spraying heads 6 are connected to the liquid outlet pipe 11 through spring tubes 15. The design of the spring tubes 15 allows the glue spraying heads 6 to maintain a certain degree of flexibility during the glue spraying process, while avoiding uneven glue spraying or pipe damage caused by pipes that are too long or too short.

[0024] As described above, the automotive plastic parts surface spraying equipment of this utility model can effectively achieve high-efficiency spraying of automotive plastic parts, while also having glue recovery and filtration functions. During the spraying process, the rodless cylinder 4 drives the spraying head 6 to spray the plastic parts comprehensively, and excess water-based glue drips into the collection tank 13 for recycling, avoiding waste. The filter screen 16 in the glue storage tank 8 can filter impurities in the water-based glue, ensuring its recycling. At the same time, the design of the multi-section electric push rod 14 allows the sprayed plastic parts to be lifted up, making it easy for workers to pick them up and improving work efficiency. This spraying equipment has a reasonable structure and practical functions, and is particularly suitable for the spraying of automotive plastic parts.
