Description

Technical Field

[0001] This utility model relates to the field of visual inspection technology, specifically a rotating tray-type multi-faceted appearance inspection device. Background Technology

[0002] Visual inspection uses machines to replace human eyes for measurement and judgment. Machine vision products, i.e., image acquisition devices, convert the captured target into image signals and transmit them to a dedicated image processing system. Based on pixel distribution and information such as brightness and color, the signals are converted into digital signals. The image system performs various operations on these signals to extract the target's features and then controls the on-site equipment based on the judgment results.

[0003] Currently, most inspection methods rely on mechanical transmission or manual operation. Since the dimensions of the workpieces to be inspected vary, excessively high rotation speeds can affect the accuracy of appearance inspection, easily causing positional deviations and failing to meet the demands of high-precision scenarios. Furthermore, the inspection equipment is generally fixed, making it difficult to adjust its position according to the workpiece's dimensions. Utility Model Content

[0004] The purpose of this invention is to provide a rotating tray-type multi-faceted appearance inspection device to solve the problems raised in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rotating tray-type multi-faceted appearance inspection device, comprising a base, a transverse guide rail, a servo motor, and a bevel gear. A turntable is arranged directly above the base, and a shifting mechanism is arranged directly below the turntable. The shifting mechanism drives the bottom end of the turntable to rotate through a toothed ring disc, thereby adjusting the inspection position on the turntable. A positioning mechanism is arranged on one side of the base. The positioning mechanism adjusts the distance between the inspection equipment and the base according to the usage requirements, accommodating workpieces of corresponding heights. Simultaneously, the longitudinal guide rail adjusts the height of the inspection equipment.

[0006] As a preferred technical solution, the positioning mechanism includes a transverse guide rail, an internal thread slider, a side positioning plate, a ball screw, a longitudinal guide rail, bevel gears, a drive shaft, and a flange. The inner end of the transverse guide rail is connected to the internal thread slider, the outer side of the internal thread slider is connected to the ball screw, the outer side of the ball screw is connected to the flange, the bevel gears are engaged with another set of bevel gears, the outer side of the bevel gears is connected to the drive shaft, the top end of the internal thread slider is connected to the side positioning plate, and the inner end of the side positioning plate is welded to one side of the longitudinal guide rail.

[0007] As a preferred technical solution, the transverse guide rail is connected to the outer side of the ball screw through an internally configured internal thread slider, and both the ball screw and the drive shaft are provided with flanges on their outer sides.

[0008] As a preferred technical solution, the drive shaft is bolted to the other side of the ball screw via a flange located on the outer side.

[0009] As a preferred technical solution, the shifting mechanism includes a servo motor, a toothed ring disk, a drive shaft, and gears. The outer side of the drive shaft is keyed with bevel teeth. The servo motor is installed inside the base and is connected to the gears via a coupling. The toothed ring disk is located inside the base, and the outer side of the toothed ring disk is connected to the drive shaft. The top end of the drive shaft is connected to the bottom end of the turntable.

[0010] As a preferred technical solution, the servo motor meshes with the outer side of the toothed ring disk via a gear connected by a coupling, and the outer end of the toothed ring disk is connected to the base via a rolling bearing.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model uses a servo motor to mesh with a gear and toothed ring disc, combined with bevel gear transmission, to achieve precise position control and low-error motion transmission, thereby improving detection and positioning accuracy. By changing the control gear with different numbers of teeth, the rotation speed of the turntable can be flexibly adjusted to meet the processing requirements of different workpieces. The rolling bearing connects the toothed ring disc and the base, reducing friction and vibration and ensuring the stability of the equipment during long-term operation.

[0013] 2. This utility model uses a transverse ball screw drive to move the internal thread slider and the side positioning plate. The side positioning plate is connected to the longitudinal guide rail, which provides the basis for subsequent possible longitudinal positioning or movement. Under the drive of the ball screw, the internal thread slider can move accurately to the specified transverse position. Combined with the side positioning plate and the longitudinal guide rail, precise positioning in a two-dimensional plane is achieved. The transverse guide rail provides precise guidance for the linear movement of the internal thread slider, ensuring the accuracy of its displacement. Attached Figure Description

[0021] 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.

[0022] Example: Figure 1 and Figure 2 , Figure 6 As shown, this utility model provides the following technical solution: a rotating tray type multi-faceted appearance inspection device, including a base 1, a transverse guide rail 3, a servo motor 8, and a bevel gear 14. A turntable 2 is arranged directly above the base 1, and a shifting mechanism 7 is arranged directly below the turntable 2. The shifting mechanism 7 drives the bottom end of the turntable 2 to rotate through a toothed ring disc 9, thereby adjusting the inspection position on the turntable 2. A positioning mechanism 6 is arranged on one side of the base 1. The positioning mechanism 6 adjusts the distance between the inspection equipment and the base 1 according to the usage requirements to match the workpiece of corresponding height. At the same time, the longitudinal guide rail 13 adjusts the height of the inspection equipment.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 , Figure 5As shown, the positioning mechanism 6 includes a transverse guide rail 3, an internal thread slider 4, a side positioning plate 5, a ball screw 11, a longitudinal guide rail 13, a bevel gear 14, a drive shaft 15, and a flange 16. The inner end of the transverse guide rail 3 is connected to the internal thread slider 4, and the outer side of the internal thread slider 4 is connected to the ball screw 11. The outer side of the ball screw 11 is connected to the flange 16. The bevel gear 14 is meshed with another set of bevel gears 14, and the outer side of the bevel gear 14 is connected to the drive shaft 15. The top end of the internal thread slider 4 is connected to the side positioning plate 5, and the inner end of the side positioning plate 5 is welded to one side of the longitudinal guide rail 13. The transverse guide rail 3 is connected to the outer side of the ball screw 11 through the internally provided internal thread slider 4. Both the outer side of the ball screw 11 and the drive shaft 15 are provided with flanges 16. The drive shaft 15 is bolted to the other side of the ball screw 11 through the outer flange 16.

[0024] Among them, the transverse guide rail 3 is connected to the ball screw 11 through the internal thread slider 4. The ball screw 11 accurately converts the rotational motion into linear motion, which enables the internal thread slider 4 to drive the side positioning plate 5 and other components to move precisely laterally on the transverse guide rail 3.

[0025] like Figure 1 , Figure 2 and Figure 3 , Figure 6 As shown, the shifting mechanism 7 includes a servo motor 8, a toothed ring disk 9, a drive shaft 10, and a gear 12. The outer side of the drive shaft 10 is keyed with bevel gears 14. The servo motor 8 is installed inside the base 1 and is connected to the gear 12 via a coupling. The toothed ring disk 9 is located inside the base 1, and the outer side of the toothed ring disk 9 is connected through the drive shaft 10. The top end of the drive shaft 10 is connected to the bottom end of the turntable 2. The gear 12 connected to the servo motor 8 via the coupling meshes with the outer side of the toothed ring disk 9. The outer end of the toothed ring disk 9 is connected to the base 1 via a rolling bearing.

[0026] Among them, the drive shaft 10 can effectively transmit power to the turntable 2, while the use of rolling bearings reduces the friction between the toothed ring disk 9 and the base 1, improving the mechanical efficiency of the mechanism. Since the main components such as the servo motor 8 and the toothed ring disk 9 are located inside the base 1, these components can be relatively well protected.

[0027] The working principle of this utility model is as follows:

[0028] During use, first connect the back of the high-resolution camera to the outside of the longitudinal guide rail 13. Adjust the height of the camera by moving the high-resolution camera to the outside of the longitudinal guide rail 13. Position the back support of the camera through the positioning holes evenly spaced on the outside of the side positioning plate 5 so that the camera and the workpiece shooting angle are set parallel, or the shooting angle of the camera is higher than the workpiece to shoot the diameter or specifications of the top hole of the workpiece.

[0029] The bevel gear 14 on the drive shaft 15 meshes with another pair of bevel gear 14. The function of this pair of bevel gears 14 is to change the transmission direction. The second bevel gear 14 is fixed on one end of the drive shaft 15. Therefore, the drive shaft 15 is connected to another set of flanges 16 through a flange 16 set on one side. The other set of flanges 16 is connected to the tail end of the ball screw 11. The rotational motion of the drive shaft 15 is transmitted to the flanges 16 through the bevel gear 14, causing them to rotate. Through the hard connection of the two sets of flanges 16, the ball screw 11 is driven to rotate. The external thread groove of the ball screw 11 is embedded with balls, and the internal thread slider 4 has a nut structure that matches the ball screw 11.

[0030] When the ball screw 11 rotates, the balls circulate between the thread groove of the screw and the nut raceway of the internal thread slider 4. The rotational motion of the ball screw 11 is efficiently converted into the linear motion of the internal thread slider 4 along the axis of the ball screw 11. The force generated by the rotation forces the internal thread slider 4 and the side positioning plate 5 connected to the top to move, thereby adjusting the distance between the camera and the base 1 and adjusting the shooting position. The transmission part of the ball screw 11 can be disconnected by disassembling the two sets of flanges 16, so that the side positioning plate 5 will not be adjusted in position.

[0031] The operator activates the servo motor 8, which drives the gear 12 to rotate. The gear 12 engages with the toothed ring disk 9, which rotates via the transmission shaft 10 at its top. The toothed ring disk 9 then drives the transmission shaft 10 and the turntable 2 to rotate, which in turn rotates the workpiece. By controlling the gear ratio between the gear 12 and the toothed ring disk 9, the rotation speed of the toothed ring disk 9 is controlled. In conjunction with a camera, the product is photographed from multiple angles to record any defects in its appearance.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
