[0041] Embodiment 1:
[0042] See also Figure 1-Figure 4 This embodiment provides a spraying system, including a roughness detection device, a spraying device 5 and a transport device 6, wherein the transport device 6 is arranged between the roughness detection device and the spraying device 5. The box 100 is first sandblasted at the spraying device 5, and then transported by the transport device 6 to the roughness detection device for roughness detection to determine whether the sandblasting on the box 100 is uniform and whether the sandblasting thickness meets the requirements. If it is detected that the sandblasting on the box 100 is insufficient, the transport device 6 transports the box 100 back to the spraying device 5 for secondary spraying. If it is detected that the sandblasting on the box 100 is too much, the box 100 needs to be reworked separately.
[0043] See also Figure 5 and Figure 6 The box 100 in this embodiment is generally a rectangular parallelepiped, and a cavity 101 is arranged inside the box 100. The cavity 101 extends to the bottom of the box 100. Correspondingly, the cavity 101 has a top wall and four side walls. The box 100 can be used as a shell of a cooking device such as an oven and a steamer.
[0044] Correspondingly, the spraying device 5 includes a housing 51 and a spray head 52, and a spraying chamber 53 is arranged inside the housing 51. Figure 2 and Figure 3 There are multiple nozzles 52 and they are located in the spraying chamber 53. The nozzles 52 can rotate to sandblast the entire top wall and all the side walls of the cavity 101 through the bottom opening of the cavity 101.
[0045] The operation mode of the nozzle 52 is prior art and will not be described in detail in this embodiment. Through research, it is found that in the process of sandblasting by the entire nozzle 52, the top wall of the cavity 101 will always remain opposite to some nozzles 52, while the side walls of the cavity 101 will be staggered with all nozzles 52 in individual time periods, which can easily lead to a relatively long sandblasting time at the top wall of the cavity 101, and easily lead to the sandblasting thickness at the top wall of the cavity 101 being greater than the sandblasting thickness at the side walls of the cavity 101, and the sandblasting thickness at the side walls of the cavity 101 being thin. When the box 100 finishes the first sandblasting and the above phenomenon is detected by the roughness detection device, it is necessary to transport the box 100 back to the inside of the spray chamber 53 through the conveying device 6 to perform a second sandblasting on the side walls of the box 100.
[0046] In order to enable the roughness detection device to identify the occurrence of the above phenomenon, the roughness detection device includes a base 1, a first telescopic device 2, a second telescopic device 3 and a third telescopic device 4. The first telescopic device 2, the second telescopic device 3 and the third telescopic device 4 can be electric or pneumatic telescopic devices.
[0047] See also Figure 7-Figure 10 The first telescopic device 2 is mounted on the base 1, and the axial direction of the first telescopic device 2 is perpendicular to the horizontal plane, so the first telescopic device 2 can be telescoped in the direction perpendicular to the horizontal plane. The second telescopic device 3 and the third telescopic device 4 are both mounted on the first telescopic device 2, so the first telescopic device 2 can drive the second telescopic device 3 and the third telescopic device 4 to move in the direction perpendicular to the horizontal plane during the telescopic process.
[0048] A supporting surface 11 is provided on the base 1, and an escape opening 12 is opened in the middle of the supporting surface 11. After the transport device 6 transports the box 100 to the base 1 and releases the box 100, the opening edge of the cavity 101 can be supported on the supporting surface 11, and the cavity 101 and the escape opening 12 are connected up and down, so that the second telescopic device 3 and the third telescopic device 4 can be moved to the top of the escape opening 12 through the first telescopic device 2 to enter the cavity 101, or moved to the bottom of the escape opening 12 through the first telescopic device 2 to exit the cavity 101.
[0049] The second telescopic device 3 is provided with a first roughness detector 31, and the third telescopic device 4 is provided with a second roughness detector 41. When the second telescopic device 3 and the third telescopic device 4 enter the cavity 101, the second telescopic device 3 and the third telescopic device 4 can be further extended, so that the first roughness detector 31 moves toward the top wall of the cavity 101, and the second roughness detector 41 moves toward the side wall of the cavity 101, and then is used to detect the roughness of the top wall of the cavity 101 and the side wall of the cavity 101 respectively.
[0050] Combined with the shape of the box 100, the second telescopic device 3 is parallel to the first telescopic device 2, and the third telescopic device 4 is perpendicular to the second telescopic device 3. Further, corresponding to the number of the side walls of the cavity 101, there are at least four third telescopic devices 4, and all the third telescopic devices 4 are sequentially arranged along the circumference of the first telescopic device 2, so that the four side walls of the cavity 101 can obtain the corresponding third telescopic devices 4, so as to use the second roughness detector 41 on the corresponding third telescopic device 4 to perform roughness detection.
[0051] In order to improve the stability of the roughness detection process, it is necessary to reduce some unnecessary shaking of the box 100 on the support surface 11, and for this purpose, a first stopper 13 can be provided on the support surface 11. The first stopper 13 can be a rib, and the shape of the first stopper 13 is adapted to the shape of the opening edge of the box 100, so when the opening edge of the box 100 is supported on the support surface 11, the first stopper 13 can limit the box 100, thereby limiting the horizontal shaking of the box 100.
[0052] In order to prevent the first telescopic device 2 from being over-extended and colliding with the top wall and / or side wall of the cavity 101, thereby damaging the sandblasting on the top wall and / or side wall of the cavity 101, see Fig.10 In this embodiment, preferably, a second stopper 21 is provided on the first telescopic device 2. Commonly, the second stopper 21 can be a flat plate, and the second stopper 21 is located below the avoidance opening 12. Among them, at least part of the projection of the second stopper 21 in the axial direction of the first telescopic device 2 is located outside the avoidance opening 12, so the second stopper 21 cannot move above the avoidance opening 12. Accordingly, under the cooperation of the second stopper 21 and the avoidance opening 12, the extension length of the first telescopic device 2 can be effectively limited.
[0053] See again Figure 1 , Figure 2 and Figure 4 In this embodiment, the transport device 6 includes a slide rail 61 and a manipulator 62 slidably arranged on the slide rail 61, wherein the slide rail 61 is mounted on the top of the casing 51, and a sliding opening 511 is arranged on the top of the casing 51, and the sliding opening 511 is connected to the spraying chamber 53. During the movement of the manipulator 62, the casing 51 avoids the manipulator 62 through the sliding opening 511 to allow the manipulator 62 to enter the spraying chamber 53, thereby allowing the manipulator 62 to lift the box 100 during the sandblasting process.
[0054] In addition, the projection of the slide rail 61 in the axial direction of the first telescopic device 2 falls on the first telescopic device 2, so the manipulator 62 can move to just above the first telescopic device 2, thereby ensuring that the first telescopic device 2 can enable the second telescopic device 3 and the third telescopic device 4 to enter the cavity 101.
[0055] Similarly, at least part of the projection of the nozzle 52 in the axial direction of the first telescopic device 2 falls on the slide rail 61, so the robot 62 can transfer the box 100 to just above the nozzle 52. At this time, the nozzle 52 can complete the sandblasting operation on the entire top wall and side walls of the cavity 101 only by rotating.
[0056] Further preferably, the manipulator 62 can not only slide on the slide rail 61, but also move axially along the first telescopic device 2. After the manipulator 62 transfers the box 100 to just above the spray head 52, the manipulator 62 can move downward to allow the spray head 52 to enter the cavity 101, so as to reduce the occurrence of mortar splashing outside the box 100.
[0057] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0058] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
