Description

Technical Field

[0001] This utility model relates to the field of positioning device technology, specifically a positioning device for visual inspection. Background Technology

[0002] Visual inspection is a method of non-contact inspection and analysis of objects using optical imaging systems and image processing technology. In mold production, the mold needs to be fixed on a positioning device for subsequent visual inspection using an industrial camera. Visual inspection allows for precise measurement of the mold's critical dimensions, ensuring they are within the design tolerances and guaranteeing that the produced products meet dimensional specifications. Defects such as scratches, cracks, and pinholes on the mold surface will be replicated on the product surface, affecting its appearance and performance. Visual inspection can quickly detect these subtle defects, allowing for timely mold repair and preventing the production of defective products.

[0003] Based on the above, the inventors have discovered the following problems: Currently, when the mold to be inspected is fixed on the positioning device and then visually inspected using an industrial camera, the position of the mold is not easy to adjust. This means that the fixed-position industrial camera can only visually inspect one side of the mold. When it is necessary to inspect other sides of the mold, it may be necessary to manually remove the mold from the positioning device and reposition it. This process is time-consuming and labor-intensive, reducing the overall inspection efficiency.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings, and provide a positioning device for visual inspection in order to achieve a more practical value. Utility Model Content

[0005] The purpose of this invention is to provide a positioning device for visual inspection to solve the problems mentioned in the background art.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A positioning device for visual inspection includes an adjustment component and a positioning component. The positioning component is disposed above the adjustment component and is used to adjust the position of the positioning component. The positioning component is used to fix the mold to be inspected. The positioning component includes a base frame, and a positioning platform is installed on the upper end of the base frame. The adjustment component includes a fixed seat, and a rotating shaft is rotatably connected inside the fixed seat. The upper end of the rotating shaft extends through the fixed seat to the outside and is connected to the bottom end of the base frame. A gear is sleeved on the outside of the rotating shaft. An electric slide rail is installed on the bottom inside the fixed seat. An electric slider is slidably connected to the outside of one end of the electric slide rail. A rack is connected to the top surface of the electric slider, and the rack and the gear mesh with each other.

[0008] Furthermore, a first square hole and a second square hole are respectively provided on both sides of the outer wall of the fixing base. The inner wall of the second square hole is slidably engaged with the outer wall of the rack, and one end of the rack extends to the outside of the fixing base through the second square hole.

[0009] The beneficial effect of adopting the above-mentioned further solution is that by setting the first square hole and the second square hole, the rack can move continuously from the second square hole to the first square hole under the action of the electric slide rail and the electric slider until the left end of the rack is located in the first square hole under the action of movement.

[0010] Furthermore, the top surface of the positioning platform is provided with a horizontal groove, and a pair of vertical grooves are provided on both sides of the top surface of the positioning platform. A horizontal clamping seat is slidably connected at both ends of the horizontal groove, and a vertical clamping seat is slidably connected inside the two pairs of vertical grooves.

[0011] The beneficial effect of adopting the above-mentioned further solution is that the left and right sides of the mold are fixed by the cooperation of the horizontal groove and the horizontal clamping seat, and the front and rear sides of the mold are fixed by the cooperation of the vertical groove and the vertical clamping seat.

[0012] Furthermore, a square frame is connected to the bottom of the positioning platform, and a first bidirectional lead screw is rotatably connected inside the square frame. The first bidirectional lead screw has a pair of opposite threads on its exterior, and both ends of the first bidirectional lead screw are threadedly connected to first square seats. The outer walls of the two first square seats are slidably engaged with the inner walls of the square frame, and the top surfaces of the two first square seats are connected to the bottom surfaces of the two transverse clamping seats. The beneficial effect of this further solution is that, through the coordinated use of the square frame, the first bidirectional lead screw, and the first square seats, by rotating the first bidirectional lead screw, due to the pair of opposite threads on its exterior and the slidable engagement between the outer walls of the first square seats and the inner walls of the square frame, the two first square seats move in opposite directions, thereby driving the transverse clamping seats to move, automatically clamping or releasing the mold to be inspected in the transverse direction.

[0013] Furthermore, support plates are connected to both sides of the bottom surface of the frame, and a second bidirectional lead screw is rotatably connected between a pair of support plates. The second bidirectional lead screw has a pair of opposite threads on its outer side, and two slide blocks are connected to the outer threads of the second bidirectional lead screw. Each of the two slide blocks has a sliding groove at its upper end, and a slide bar is provided between a pair of sliding grooves. The top surface of the slide bar is connected to the bottom surface of the frame, and the inner wall of the sliding groove slides in slidable engagement with the outer wall of the slide bar. Connecting rods are hinged to both sides of the outer side of the two slide blocks, and a second square seat is hinged to the end of the connecting rod away from the slide block. The top surface of the second square seat is connected to the bottom surface of the vertical clamping seat.

[0014] The beneficial effect of adopting the above-mentioned further solution is that, through the coordinated use of the second bidirectional lead screw, slide block and slide bar, by rotating the second bidirectional lead screw, due to the pair of opposite threads on its exterior and the sliding connection between the second square block and the slide bar, the two first square blocks move in opposite directions. When the two slide blocks move in opposite directions to both sides, under the action of the connecting rod, the pair of second square blocks on the same side are pulled closer together, and the mold to be tested is automatically clamped in the vertical direction.

[0015] Furthermore, a first servo motor is installed on one side of the outer wall of the frame, and the output end of the first servo motor is connected to the first bidirectional lead screw.

[0016] The beneficial effect of adopting the above-mentioned further solution is that by setting a first servo motor, it is easier to realize the rotation of the first bidirectional lead screw when the first servo motor is working.

[0017] Furthermore, a second servo motor is installed on one side of the outer wall of one of the support plates, and the output end of the second servo motor is connected to a second bidirectional lead screw.

[0018] The advantage of adopting the above-mentioned further solution is that by setting a second servo motor, it is easier to realize the rotation of the second bidirectional lead screw when the second servo motor is working.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: When the first servo motor is started, it drives the first bidirectional lead screw to rotate. Because the first bidirectional lead screw has a pair of opposite threads on its outer side, and the outer wall of the first square seat slides against the inner wall of the frame, the two first square seats move towards the center, thereby driving the lateral clamping seat to move and automatically clamping the mold to be inspected in the lateral direction. When the second servo motor is started, it drives the second bidirectional lead screw to rotate. Because the second bidirectional lead screw has a pair of opposite threads on its outer side, and the second square seat is slidably connected to the slide bar, the two first square seats move towards each other. When the two slide bars move towards each other on both sides... During operation, the connecting rod pulls a pair of second seats on the same side closer together, automatically clamping the mold to be inspected vertically. This allows the industrial camera to visually inspect the side of the mold on the positioning table. During the inspection, the fixed position of the industrial camera allows only one side of the mold to be visually inspected. Through the cooperation of the electric slide rail and the electric slider, the rack moves to the left under the action of the electric slider. Due to the meshing of the rack and gear, the rotating shaft is rotated. Since the top surface of the rotating shaft is fixedly connected to the bottom surface of the base frame, the entire positioning assembly is rotated, allowing the industrial camera to visually inspect the other surfaces of the mold on the positioning table in sequence.

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.

[0026] Please see Figures 1-4This utility model provides a technical solution: a positioning device for visual inspection, including an adjustment component 1 and a positioning component 2. The positioning component 2 is disposed above the adjustment component 1. The adjustment component 1 is used to adjust the position of the positioning component 2, and the positioning component 2 is used to fix the mold to be inspected. The positioning component 2 includes a base frame 21, and a positioning platform 22 is installed on the upper end of the base frame 21. The adjustment component 1 includes a fixed seat 11, and a rotating shaft 12 is rotatably connected inside the fixed seat 11.

A gear 13 is sleeved on the outside of the rotating shaft 12. An electric slide rail 14 is installed on the bottom inside the fixed seat 11. An electric slider is slidably connected to one end of the electric slide rail 14. A rack 15 is connected to the top surface of the electric slider. The rack 15 and the gear 13 mesh with each other. The outer wall of the mold has a first square hole 16 and a second square hole on each side. The inner wall of the second square hole slides with the outer wall of the rack 15. One end of the rack 15 extends to the outside of the fixed base 11 through the second square hole. During the inspection, the fixed position of the industrial camera allows only one side of the mold to be visually inspected. Through the cooperation of the electric slide rail 14 and the electric slider, the rack 15 moves to the left under the action of the electric slider, so that the right end of the rack 15 separates from the second square hole. The left end of the rack 15 moves continuously and is located outside the fixed base 11 through the first square hole 16. Since the rack 15 and the gear 13 mesh, the rotating shaft 12 is rotated. Since the top surface of the rotating shaft 12 is fixedly connected to the bottom surface of the base frame 21, the entire positioning assembly 2 is rotated, so that the industrial camera can visually inspect the other surfaces of the mold on the positioning table 22 in sequence.

[0027] 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.

[0028] Please see Figures 1-4This utility model provides a technical solution: a horizontal groove 23 is provided on the top surface of the positioning platform 22, and a pair of vertical grooves 24 are provided on both sides of the horizontal groove 23 on the top surface of the positioning platform 22. A horizontal clamping seat 25 is slidably connected to both ends of the horizontal groove 23, and a vertical clamping seat 26 is slidably connected to the inside of the two pairs of vertical grooves 24. A square frame 27 is connected to the bottom end of the positioning platform 22, and a first bidirectional lead screw 28 is rotatably connected inside the square frame 27. A pair of opposite threads are provided on the outside of the first bidirectional lead screw 28, and a first square seat 29 is threaded to both ends of the first bidirectional lead screw 28. The outer walls of the two first square seats 29 are slidably engaged with the inner walls of the square frame 27, and the top surface of the two first square seats 29 is... The frame 27 is connected to the bottom surfaces of two transverse clamping seats 25 respectively. Support plates 211 are connected to both sides of the bottom surface of the frame 27. A second bidirectional lead screw 212 is rotatably connected between the pair of support plates 211. The second bidirectional lead screw 212 has a pair of opposite threads on its exterior. Two slide seats 214 are connected to the external threads of the second bidirectional lead screw 212. Each slide seat 214 has a groove at its upper end. A slide bar 213 is provided between the pair of grooves. The top surface of the slide bar 213 is connected to the bottom surface of the frame 27. The inner wall of the groove slides slides against the outer wall of the slide bar 213. Connecting rods 216 are hinged to both sides of the exterior of the two slide seats 214. A second square seat 215 is hinged to the end of the connecting rod 216 away from the slide seat 214. The top surface of the second square seat 215 is connected to the bottom surface of the vertical clamping seat 26. A first servo motor 210 is installed on one side of the outer wall of the frame 27. The output end of the first servo motor 210 is connected to the first bidirectional lead screw 28. A second servo motor 217 is installed on one side of the outer wall of one of the support plates 211. The output end of the second servo motor 217 is connected to the second bidirectional lead screw 212. By setting the first servo motor 210, when the first servo motor 210 is started, it drives the first bidirectional lead screw 28 to rotate. Since the first bidirectional lead screw 28 has a pair of opposite threads on its outer side, and the outer wall of the first square seat 29 slides against the inner wall of the frame 27, the two first square seats 29 face the center. The moving center moves in opposite directions, thereby moving the transverse clamping seat 25 to automatically clamp the mold to be inspected in the transverse direction. By setting a second servo motor 217, when the second servo motor 217 is started, it drives the second bidirectional lead screw 212 to rotate. Since the second bidirectional lead screw 212 has a pair of opposite threads on its outside and the second square seat 215 is slidably connected to the slide bar 213, the two first square seats 29 move in opposite directions. When the two slide seats 214 move in opposite directions to both sides, under the action of the connecting rod 216, the pair of second square seats 215 on the same side are pulled closer to automatically clamp the mold to be inspected in the vertical direction, so that the industrial camera can perform visual inspection of the side of the mold on the positioning stage 22.Specifically, the working principle of this visual inspection positioning device is as follows: When the first servo motor 210 is activated, it drives the first bidirectional lead screw 28 to rotate. The outer wall of the first square seat 29 slides against the inner wall of the frame 27, causing the two first square seats 29 to move towards the center, thereby moving the transverse clamping seat 25 to automatically clamp the mold to be inspected in the transverse direction. When the second servo motor 217 is activated, it drives the second bidirectional lead screw 212 to rotate. The second square seat 215 slides against the slide bar 213, causing the two first square seats 29 to move towards each other. When the two slide bars 214 move towards each other on both sides, under the action of the connecting rod 216, they pull the pair of second square seats 215 on the same side closer together, automatically clamping the mold to be inspected in the vertical direction. The machine is clamped to allow the industrial camera to visually inspect the side of the mold on the positioning stage 22. During the inspection, the fixed position of the industrial camera allows only one side of the mold to be visually inspected. Through the cooperation of the electric slide rail 14 and the electric slider, the rack 15 moves to the left under the action of the electric slider, causing the right end of the rack 15 to separate from the second square hole. The left end of the rack 15 moves continuously and passes through the first square hole 16 to the outside of the fixed base 11. Since the rack 15 and the gear 13 mesh, the rotating shaft 12 is rotated. Since the top surface of the rotating shaft 12 is fixedly connected to the bottom surface of the base frame 21, the entire positioning assembly 2 is rotated, so that the industrial camera can visually inspect the other sides of the mold on the positioning stage 22 in sequence.
