[0014] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0015] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present invention.

[0016] As Figures 1 - 5 shown, in some embodiments, a surface spraying device for a tool clamp includes a conveying assembly 1 and a surface treatment assembly, and the surface treatment assembly is arranged on one side of the conveying assembly 1. The tool clamp to be sprayed is conveyed to the surface treatment assembly by the conveying assembly 1, and after a series of treatments here, it is continuously conveyed out of the surface treatment assembly by the conveying assembly 1 to complete the surface spraying operation of the tool clamp. Through the cooperation between the conveying assembly 1 and the surface treatment assembly, while improving the surface spraying quality of the tool clamp, the spraying efficiency of the tool clamp is also improved.

[0017] Specifically, the conveying assembly 1 includes a guide rail 12, a suspension rod 13 and a conveying chain 14. The conveying chain 14 is arranged in the guide rail 12. The suspension rod 13 passes through the guide rail 12 and is connected to the tool clamp. The conveying chain 14 drives the suspension rod 13 to move along the guide rail 12, thereby realizing the conveyance of the tool clamp. This design not only improves the working efficiency, but also ensures the stability and safety of the tool clamp during the spraying process.

[0018] It should be noted that the surface treatment assembly sequentially includes a cleaning mechanism 2, a spraying mechanism and a drying mechanism 5 along the moving direction of the tool clamp. First, when the tool clamp passes through the cleaning mechanism 2, the cleaning mechanism 2 adsorbs residues such as dust or oil stains on its surface, thereby ensuring the cleanliness of the tool clamp surface and providing a good basis for subsequent spraying work. Secondly, the spraying mechanism 4 is responsible for spraying paint on the surface of the tool clamp to achieve the purpose of decoration or protection. Finally, the drying mechanism 5 is arranged on one side of the guide rail 12 and is used for drying the tool clamp after spraying to ensure that the paint can dry quickly.

[0019] Specifically, the drying mechanism 5 includes a baffle 52, and the baffle 52 is used to adjust the air volume output of the drying mechanism 5 to adapt to tool clamps of different sizes and shapes and ensure the drying effect. This design of the drying mechanism 5 not only improves the drying efficiency, but also can flexibly adjust the drying parameters according to the different requirements of the tool clamp, so as to achieve the best drying effect.

[0020] In this embodiment, the specific operation process includes: A discharge port and a loading port are provided at one end of the conveying assembly 1, and the two loading ports are close to each other. At the loading port, the tool tongs are suspended on the conveying assembly 1 through a hanging rod 13. As the conveying chain 14 rotates, the tool tongs are driven along the guide rail 12 to the surface treatment assembly.

[0021] After the tool pliers arrive at the surface treatment component, they first pass through the cleaning mechanism 2, which can absorb dust or oil stains and other residues on the surface of the tool pliers to ensure the cleanliness of the surface of the tool pliers. Subsequently, the spraying mechanism 4 sprays the paint on the surface of the tool pliers. During the spraying process, the impact force generated by the spray head will cause the tool pliers to rotate, thereby achieving uniform spraying on the surface of the tool pliers, and the notches of the tool pliers can also be evenly sprayed. Finally, the sprayed tool pliers continue to move to the drying mechanism 5. The drying mechanism 5 will adjust the position of the baffle 52 according to the size of the tool pliers to ensure that the hot air fully acts on the surface of the tool pliers and effectively dries the paint.

[0022] After spraying is completed, remove the tool pliers at the discharge port. At this point, the spraying operation of the tool pliers is completed.

[0023] In this series of processes, the cleaning mechanism 2 effectively removes dust or oil stains and other residues on the surface of the tool pliers, ensures the cleanliness of the surface, and effectively improves the adsorption of the paint on the surface of the tool pliers. The coordinated work of the spraying mechanism 4 and the drying mechanism 5 not only improves the spraying quality, but also improves the production efficiency of the spraying.

[0024] Furthermore, in some embodiments, the spraying device further comprises a housing 3, and the surface treatment component is disposed in the housing 3. The interior of the housing 3 is divided into three main areas, namely a cleaning chamber 31, a spraying chamber 33, and a drying chamber 34. In order to ensure the functional independence of the three areas, a partition 32 is provided between the spraying chamber 33 and the cleaning chamber 31 and the drying chamber 34, respectively.

[0025] Specifically, in the cleaning chamber 31 , the cleaning mechanism 2 is correspondingly arranged therein so as to clean the tool pliers, thereby ensuring that the tool pliers are in a clean state before entering the spray chamber 33 .

[0026] In particular, the spray chamber 33 is equipped with a fixing plate 331 and a signal receiver. The spray mechanism 4 is connected to the fixing plate 331 to ensure the stability and reliability of the spray mechanism 4 during the spraying process. In addition, the fixing plate 331 and the housing 3 are designed to be movably connected, which is convenient for maintenance and repair of the spray mechanism 4 and the spray chamber 33.

[0027] The signal receiver is electrically connected to the spraying mechanism 4. The main function of the signal receiver is to detect the position of the suspension rod 13. When the suspension member 13 carrying the tool clamp reaches here, the spraying mechanism 4 receives the signal and starts the spraying operation on the tool clamp, which can avoid waste of paint and make the whole spraying process more efficient and accurate. Through the above design, the spraying mechanism 4 can maintain precise positioning when performing its function, thus ensuring the uniformity and consistency of spraying.

[0028] Finally, the drying mechanism 5 is correspondingly arranged with the drying chamber 34. After the tool clamp is sprayed, it will enter the drying chamber 34 for drying treatment. The drying mechanism 5 is responsible for providing the necessary heat source to accelerate the drying process of the coating, ensuring that the coating can be cured quickly and evenly, so as to achieve the ideal surface effect.

[0029] Furthermore, in some embodiments, there are multiple cleaning mechanisms 2, and these cleaning mechanisms 2 are arranged in sequence along the guide rail 12. Each cleaning mechanism 2 includes a second driving motor 21, a rotating shaft 22 and an adsorption brush 23.

[0030] Among them, the second driving motor 21 is fixedly connected to the outer wall of the housing 3. One end of the rotating shaft 22 is in transmission connection with the second driving motor 21, and the adsorption brush 23 is arranged on the rotating shaft 22. Driven by the second driving motor 21, the rotating shaft 22 and the adsorption brush 23 can rotate, so as to realize the cleaning of the surface of the tool clamp. This design enables each cleaning mechanism 2 to independently clean the tool clamp. At the same time, since the cleaning mechanisms 2 are arranged along the guide rail 12, the position of each cleaning mechanism 2 can be flexibly adjusted to adapt to tool clamps of different sizes and shapes.

[0031] Furthermore, in some embodiments, the spraying mechanism includes multiple nozzles, and these nozzles are vertically arranged in sequence along the fixed plate 331. Each nozzle can be independently controlled. In particular, each nozzle is provided with two oppositely arranged spraying ports, and these spraying ports are designed to spray paint onto the surface of the tool clamp. This design makes the spraying process more flexible and precise, because each nozzle can be individually adjusted and operated according to the specific needs of the tool clamp. In addition, the opposite arrangement of the spraying ports ensures that the paint can evenly cover all parts of the tool clamp, thus improving the quality and efficiency of spraying.

[0032] Furthermore, in some embodiments, the drying mechanism 5 further includes a drying frame 51 and a wedge 53. Specifically, one side of the drying frame 51 is tightly connected to one side of the drying chamber 34 to ensure the stability of the drying frame 51. Inside the drying frame 51, a slide groove structure is specially designed so that the baffle 52 can slide smoothly therein. In order to ensure the hot air circulation during the drying process, a plurality of vents 511 are provided on the other side of the drying frame 51. These vents 511 are carefully arranged in an array to achieve the best ventilation effect, so as to ensure that the air can evenly pass through the drying frame 51, thereby providing a uniform drying environment for the surface of the tool pliers.

[0033] It is worth noting that the drying frame 51 is located in the central area of the drying chamber. When the sprayed tool pliers first enter the drying chamber, the temperature is relatively low. As the tool pliers move forward, it gradually approaches the vent hole 511, and the temperature gradually increases. As the tool pliers continue to move, the temperature will gradually decrease. This temperature change ensures that the temperature of the entire drying process is not constant, thereby avoiding the potential negative impact of direct high temperature on the drying quality.

[0034] The bottom of the baffle 52 is designed with a horizontal plate 521, which is connected to the inner wall of the drying frame 51 by sliding. The horizontal plate 521 also plays the role of dividing the internal space of the drying frame 51, making the drying process more efficient. The addition of the horizontal plate 521 effectively divides the internal space of the drying frame 51 into two areas. The wind heat passes through the vent holes in the upper area of the horizontal plate 521 and blows hot air to the surface of the tool pliers. The positions of the baffle 52 and the horizontal plate 521 are adjusted according to the size of the tool pliers to reduce unnecessary energy loss.

[0035] In addition, a plurality of limit grooves are provided on both side edges of the baffle 52, and the function of these limit grooves is to be correspondingly connected with the wedge block 53. Through the precise cooperation of the wedge block 53, the accurate positioning of the baffle 52 in the slide groove can be ensured, thereby ensuring the stability of the baffle 52.

[0036] Furthermore, in some embodiments, the conveying assembly 1 further includes a first drive motor 11, which is in transmission connection with the conveying chain 14, so that the first drive motor 11 can drive the conveying chain 14 to rotate. In addition, the first drive motor 11 also has the function of adjusting the speed to meet the needs of different spraying operations and ensure the uniformity and consistency of the spraying quality.

[0037] In particular, a corresponding upper cover 121 is provided on the upper portion of the guide rail 12. The main function of the upper cover 121 is to seal the guide rail 12 to prevent dust and impurities from entering the guide rail 12 and affecting its normal operation. At the same time, the upper cover 121 is also fixedly connected to the guide rail 12 to support and fix the guide rail 12.

[0038] Between the guide rails 12, a support frame 122 is specially designed. The support frame 122 is fixedly connected to the guide rail 12 through a connecting buckle, which can effectively enhance the stability of the guide rail 12 and ensure its stability and reliability during operation. In addition, a chute is provided at the bottom of the guide rail 12, and the design of the chute enables the suspension rod 13 to rotate flexibly along the guide rail 12.

[0039] A plurality of stoppers 141 are provided on the conveyor chain 14. These stoppers 141 are arranged in sequence along the conveyor chain 14. Their main function is to connect with the suspension rod 13. When the conveyor chain 14 rotates, the stopper 141 can push the suspension rod 13 to move, so as to achieve precise control and positioning of the tool clamp and ensure the accuracy and consistency of the spraying process. Each stopper 141 is provided with a flexible pad on the side connected to the suspension rod 13. Through this design, the vibration and impact generated during movement can be absorbed, further improving the positioning accuracy of the tool clamp and the stability of the spraying operation.

[0040] As Figures 1 - 6 shown, in some embodiments, the suspension rod 13 includes a slider 131, a connecting rod 132, and a hanging hole 133. The slider 131 is designed to be slidably disposed inside the guide rail 12 for easy movement on the guide rail 12, and the outer wall of the connecting rod is slidably connected to the chute as the slider 131 moves.

[0041] A signaler is provided on the upper part of the slider 131. The signaler can emit a signal to the signal receiver to determine the position of the suspension rod 13. In this embodiment, the signaler can also detect whether the tool clamp is suspended on the suspension rod 13 and further judge the size or model of the tool clamp according to the weight of the tool clamp, so that the signal receiver can judge whether to activate the spraying mechanism and the number of nozzles to be opened according to its signal. Through this design, the tool clamp can be sprayed more effectively, and at the same time, the waste of paint can be effectively avoided.

[0042] A groove is provided at the lower part of the slider 131, and one end of the connecting rod 132 is pivotally connected to the groove on the slider 131. This connection method can ensure a stable connection between the connecting rod 132 and the slider 131, and at the same time provide a certain degree of rotational freedom. The hanging hole 133 is provided at the other end of the connecting rod 132. This design enables the suspension rod 13 to be connected to the hook through the hanging hole 133, thereby realizing the function of fixing the suspension rod 13 or suspending the tool clamp. Through such a structural design, the suspension rod 13 can be stably fixed on the guide rail 12 and can also be conveniently connected to other components, thus realizing the stable operation of the surface spraying device of the tool clamp.

[0043] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.

[0044] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
