[0035] In an embodiment of the present utility model, as Figures 1 to 4 shown, a conveying mechanism is provided, which includes a lifting and weighing assembly 10 and two conveying assemblies 20; the two conveying assemblies 20 are distributed parallel to each other;

[0036] The lifting and weighing assembly 10 includes a base 11, a lifting cylinder 12, a connecting member 13, a bearing member 14 and a weighing member 15; the base 11 is arranged between the two conveying assemblies 20, the lifting cylinder 12 is installed on the base 11, the connecting member 13 is fixedly connected to the lifting cylinder 12, the connecting member 13 is slidably connected to the base 11, the weighing member 15 is connected between the upper end of the connecting member 13 and the bottom surface of the bearing member 14, and a limiting column 16 is arranged on the bearing member 14.

[0037] Specifically, the two conveying assemblies 20 transfer the product to the lifting and weighing assembly 10. The lifting cylinder 12 drives the connecting member 13 to rise, and then drives the bearing member 14 to rise. The bearing member 14 lifts the product off the surfaces of the two conveying assemblies 20, and the limiting column 16 prevents the product from falling during the rising process. Since the weight of the product changes due to coating on the product surface, the weighing member 15 is used to sense the change in weight and cooperate with the vision detection device for detection. Further, if the vision detection device detects that the coating range is OK, the weighing member 15 is used to detect the change in weight to further determine whether the coating thickness meets the standard, improving the accuracy of coating detection.

[0038] Further, the weighing member 15 is a high-precision electronic scale, the structure of which belongs to the prior art and will not be elaborated here. In this embodiment, the high-precision electronic scale is used to sense the amount of glue coated, and then combined with the regional value detected by vision to judge the thickness value of the coating.

[0039] In another embodiment of the present invention, as Figures 1 to 4 shown, the connecting member 13 includes an upper cross plate 131, a lower cross plate 132 and a first vertical plate 133 connecting the upper cross plate 131 and the lower cross plate 132. The lower cross plate 132 is provided with an avoidance hole, and the lifting cylinder 12 passes through the avoidance hole and is connected to the base 11. The first vertical plate 133 is respectively slidably connected to the base 11. In this way, a frame structure is formed among the upper cross plate 131, the lower cross plate 132 and the first vertical plate 133, and the cylinder body of the lifting cylinder 12 is located inside the frame. Compared with the structure in which the cylinder body of the lifting cylinder 12 is installed on the base 11, this embodiment saves the installation space of the lifting cylinder 12 while satisfying the sliding connection between the first vertical plate 133 and the base 11, thereby reducing the overall height of the lifting and weighing assembly 10.

[0040] In another embodiment of the present invention, as Figures 1 to 4 shown, a second vertical plate 112 is provided on the base 11. The first vertical plate 133 and the second vertical plate 112 are distributed in parallel with each other. The first vertical plate 133 is provided with a slide rail, and the second vertical plate 112 is provided with a slider, and the slider is slidably connected to the slide rail. Specifically, a second vertical plate 112 parallel to the first vertical plate 133 is provided on the base 11. By providing a slide rail and a slider between the first vertical plate 133 and the second vertical plate 112, the connection member 13 is more stable when lifting and lowering.

[0041] In another embodiment of the present invention, as Figures 1 to 4 shown, the base 11 is further provided with a third vertical plate 113. A stop member 114 is provided at the upper end of the third vertical plate 113, and the upper end of the stop member 114 is higher than the upper end surface of the transfer assembly 20. Specifically, the provided stop member 114 is used to prevent the product from falling due to inertia after the transfer assembly 20 stops moving during transfer, which plays a role in protecting the product, and at the same time improves the position when stopping, ensuring the accuracy of processing.

[0042] In another embodiment of the present invention, as Figures 1 to 4 shown, a buffer member 115 is provided on a side surface of the stop member 114 close to the carrier member 14. Specifically, the provided buffer member 115 can further protect the product.

[0043] In another embodiment of the present invention, as Figures 1 to 4As shown, one end of the stopper 114 is provided with an installation groove 116, the buffer 115 is installed in the installation groove 116, and the side wall of a part of the buffer 115 protrudes outside the installation groove 116. Specifically, during assembly, the buffer 115 can be simply installed in the installation groove 116, which is convenient and fast.

[0044] In another embodiment of the present invention, as Figures 1 to 4 shown, the installation groove 116 is a cylindrical structure. Specifically, setting the installation groove 116 as a cylindrical structure is convenient for processing.

[0045] In another embodiment of the present invention, as Figures 1 to 4 shown, the buffer 115 and the installation groove 116 are in interference fit. Specifically, the buffer 115 and the installation groove 116 are in interference fit, preventing the buffer 115 from easily falling off and improving the stability of use.

[0046] In another embodiment of the present invention, as Figures 1 to 4 shown, there are two installation grooves 116, and the buffer 115 is arranged in each of the two installation grooves 116. Specifically, since the installation groove 116 adopts a cylindrical structure, setting two installation grooves 116 improves the stability of the buffer 115 in stopping the product, that is, increases the number of point-plane contacts between the buffer 115 and the product.

[0047] In another embodiment of the present invention, as Figures 1 to 4 shown, the stopper 114 is provided with a kidney-shaped hole 117, and the fixing member passes through the kidney-shaped hole 117 and is connected to the third vertical plate 113. Specifically, the provided kidney-shaped hole 117 can facilitate the adjustment of the stopper 114.

[0048] The present invention also provides a coating machine, including the above-mentioned conveying mechanism.

[0049] Specifically, due to the adoption of the above-mentioned conveying mechanism, two conveying components 20 transfer the product to be processed to the lifting and weighing component 10. The lifting cylinder 12 drives the connecting member 13 to rise, and then drives the bearing member 14 to rise. The bearing member 14 lifts the product off the surfaces of the two conveying components 20, and the limiting column 16 prevents the product from falling during the rising process. Since the surface of the product is coated and the weight of the product changes, the weighing member 15 is used to sense the change in weight and cooperate with the vision detection device for detection. Further, if the vision detection device detects that the coating range is OK, the weighing member 15 detects the change in weight to further determine whether the coating thickness meets the standard, improving the accuracy of coating detection.

[0050] As Figures 1 to 4As shown in the figure, the coating machine further includes a robotic arm 30, a coating assembly 40, a vision inspection group of 50 parts, and a mounting bracket 60; the mounting bracket 60 is installed above the two conveying assemblies 20, the robotic arm 30 is installed on the mounting bracket 60, and both the coating assembly 40 and the vision inspection group of 50 parts are installed on the robotic arm 30 for coating and inspecting the product. Specifically, the provided robotic arm 30 drives the coating assembly 40 to process the product, and after completion, the robotic arm 30 drives the vision inspection group of 50 parts to inspect the processed product.

[0051] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
