[0028] The purpose of the utility model is to provide a thickness measuring machine to solve the problems existing in the above-mentioned prior art, so as to realize the detection of the thickness of all products and prevent the outflow of defective products.

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0030] refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, the present invention provides a thickness gauge, comprising a mounting platform 1 of a plate-like structure, on which is disposed a conveying portion and a thickness measuring device. The conveying portion is capable of horizontally conveying products to be measured; the thickness measuring device includes a thickness gauge 3, located above the conveying portion, capable of measuring the thickness of products conveyed from the conveying portion to the bottom of the thickness gauge 3.

The sensor 17 can be a photoelectric sensor 17, which is used to detect the position of products whose thickness has been measured and transmit the detection information to the control device. The manipulator can receive instructions from the control device and grasp and reject products that do not meet the thickness requirements. The control device is a hardware and software system for operating and controlling the manipulator, which is known in the art and includes a controller, a central processing unit (CPU), a memory, an input / output interface, etc., all of which are known structures.

[0031] In order to facilitate the installation of the thickness gauge 3, a thickness measuring bracket 2 is fixedly provided on the installation platform 1 in this embodiment. The thickness measuring bracket 2 is a door-type frame structure, and its bottom ends are located on both sides of the conveying part and will not interfere with the operation of the conveying part. Its top is located above the conveying part, and a thickness gauge 3 is provided on its top, which can measure the thickness of the product transported on the conveying part in real time. In order to display the product thickness information more intuitively, a display 18 is electrically connected to the thickness gauge 3 in this embodiment.

[0032] In a preferred embodiment, in order to be able to adjust the distance between the thickness gauge 3 and the product to be measured according to the thickness of the product to be measured and to facilitate the installation of the thickness gauge 3, an instrument mounting plate 4 is provided on the top of the thickness measuring bracket 2, and a cylinder 5 is fixedly provided on one side of the instrument mounting plate 4. The output shaft of the cylinder 5 is connected to the thickness gauge 3 through a connecting plate, and the end of the connecting plate away from the thickness gauge 3 is passed through the instrument guide shaft 6. The output shaft of the cylinder 5 is retracted to drive the connecting plate and the thickness gauge 3 to move up and down, thereby realizing the change of the distance between the thickness gauge 3 and the product to be measured. When the size of the product to be measured is large, in order to enable more comprehensive measurement, a horizontal slide rail can be provided on the top of the thickness measuring bracket 2, and the instrument mounting plate 4 is slidably installed on the slide rail through a slider, and a driving hydraulic rod is provided to realize the left and right movement of the instrument mounting plate 4.

[0033] In this embodiment, a film picking platform is provided on the outside of one end of the conveying part. The film picking platform is located at the end of the product processing production line. The film picking platform includes a film picking platform top plate 19. The film picking platform top plate 19 is used to place the product to be tested. The processed products are conveyed to the film picking platform top plate 19. In this embodiment, a thickness measuring grabbing mechanism is provided at one end of the conveying part close to the film picking platform. The thickness measuring grabbing mechanism includes a supporting vertical plate 7, a horizontal cylinder mounting plate 8 is provided on the top of the supporting vertical plate 7, a horizontal guide rod and a rodless cylinder 9 are provided on the horizontal cylinder mounting plate 8, a movable frame is movably provided on the horizontal guide rod, the movable frame is transmission-connected with the rodless cylinder 9, and a short material picking fixing block 10 is provided at the bottom of the movable frame. The short material picking fixing block 10 can be moved up and down by a telescopic cylinder. The short material picking fixing block 10 is a device for fixing or positioning small-sized materials, which is usually used in automated production lines, assembly lines or material handling systems. It belongs to a known technology. It can achieve positioning, ensure that the product is accurately placed in the specified position, prevent the product from moving during transportation or processing, facilitate quick product placement, improve production efficiency, ensure the positioning accuracy of the product, and is suitable for high-precision processing or assembly, so that the product to be measured on the film picking platform can be transferred to the conveying part.

[0034] In order to realize the installation of the conveying part, in one embodiment, two rows of fixed plates 21 are symmetrically provided on the mounting platform 1, and the conveying part includes a plurality of conveying shafts 12 arranged side by side. The two ends of the conveying shaft 12 are connected to the fixed plates 21 on the corresponding side by bearings. A sprocket 11 is provided at one end of the conveying shaft 12, and the sprocket 11 is connected by a closed chain transmission. The other end of one of the conveying shafts 12 is connected to a synchronous wheel 16 through a closed synchronous belt transmission. The synchronous wheel 16 is installed on the output shaft of the stepper motor 15, so that the stepper motor 15 can drive the conveying shaft 12 to rotate through the synchronous belt, thereby realizing the conveying of the product. The distance between two adjacent conveying shafts 12 is less than the length of the product to be tested, so that the product will not fall from the gap between the conveying shafts 12 during the conveying process. In order to make the conveying process safer and smoother, a conveying plate can be provided on the conveying shaft 12 for placing the product to be tested, or a closed conveyor belt can be connected to the conveying shaft 12, which can also realize the conveying of the product to be tested.

[0035] In order to prevent the product to be tested from shifting left and right on the conveyor, thereby affecting the measurement results, in a preferred embodiment, two limit frames 20 made of aluminum profiles are arranged along the moving direction of the product to be tested. The conveyor shaft 12 moves through the limit frames 20 without contacting the limit frames 20, or the conveyor shaft 12 is located below the limit frames 20, so that the limit frames 20 do not affect the rotation of the conveyor shaft 12. When the product to be tested moves on the conveyor shaft 12, it is located between the two limit frames 20 and is thus limited in its left and right position by the two limit frames 20 to prevent it from deflecting left and right. In order to accommodate products to be tested of different widths, the two limit frames 20 can be adjusted left and right so that the width between the two limit frames 20 changes according to the product to be tested. The adjustment of the limit frame 20 can adopt a screw nut structure. A guide shaft 13 and a forward and reverse screw 14 are provided between the two rows of fixed plates. The guide shaft 13 and the forward and reverse screw 14 are arranged parallel to the conveying shaft 12, and the guide shaft 13 passes through the limit frame 20 to achieve a guiding effect on the limit frame 20. The screw nut of the forward and reverse screw 14 is fixedly connected to the limit frame 20. A screw motor is connected to one end of the forward and reverse screw 14. The screw motor drives the forward and reverse screw 14 to rotate, and then the screw nut drives the corresponding limit frame 20 to move left and right to adjust its position.
