Description

Technical Field

[0001] The present application relates to the technical field of sharp edge detection devices, and more specifically, to a toy sharp edge detection device and a detection method. Background Art

[0002] Toys need to undergo various tests before leaving the factory, which is very important for the safety and health of children who will play with the toys later. Because during the process of playing with toys, various parts of a child's body may come into direct contact with the toys. If the toys have sharp edges, they may scratch the child's skin or cause more serious damage to the child's body. For this reason, toy sharp edge detection devices have been designed in the prior art to detect the sharp edges of toys. In the prior art, either a handheld sharp edge detection device is used to detect toys, which makes the detection operation inconvenient, or the toy is fixed on the detection device, and the sharp edge of the toy is made to abut against the self-adhesive tape on the rotating mandrel for detection. However, in the toy sharp edge detection devices in the prior art, after the toy is fixed on the corresponding fixture, its angle cannot be adjusted. In this way, when moving relatively close to the self-adhesive tape on the rotating mandrel, the self-adhesive tape may not be able to accurately abut against the sharp edge. Then, it is necessary to move the fixture for clamping the toy or move the rotating mandrel and loosen the toy, and then repeatedly adjust the toy to the appropriate orientation angle, which greatly reduces the test efficiency and difficulty of toy sharp edge detection.

[0051] See Figures 1 to 8 , according to one aspect of the present invention, a toy sharp edge detection device is provided. Among them, the toy sharp edge detection device includes: a base 100, which can specifically be in the form of a plate or a rack, serving as the support basis for the entire toy sharp edge detection device and can be placed on the ground, tabletop, or operating tabletop;

[0052] A first support ring plate 1, and the first support ring plate 1 is arranged on the base 100;

[0053] A second support ring plate 2, and the second support ring plate 2 is spaced on the inner ring side of the first support ring plate 1 and is rotatably connected to the first support ring plate 1 through a first rotating shaft 4;

[0054] A support plate 3, and the support plate 3 is spaced on the inner ring side of the second support ring plate 2 and is rotatably connected to the second support ring plate 2 through a second rotating shaft 5. The first rotating shaft 4 and the second rotating shaft 5 are arranged at an angle;

[0055] A rotating mandrel 6 rotatably passing through the support plate 3. The rotating mandrel 6 can fix a measuring tape. The commonly used measuring tape is a PTFE tape. The PTFE tape has a single-sided coating and is made of tetrafluoroethylene. Of course, tapes made of other suitable materials are also acceptable. Preferably, the rotating mandrel 6 has alignment lines, and the measuring tape is pasted on the rotating mandrel 6 along the alignment lines to prevent the measuring tape from being pasted unevenly;

[0056] A rotation driving mechanism arranged on the base 100. The rotation driving mechanism can be in transmission connection with the rotating mandrel 6 to drive the rotating mandrel 6 to rotate;

[0057] The first toy fixing and clamping mechanism 7 is movably arranged on the side of the support plate 3 facing away from the base 100, and is used for fixing and clamping a toy and pressing the sharp edge of the fixed and clamped toy against the measuring tape fixed on the rotating mandrel 6.

[0058] In the toy sharp edge detection device provided by the present invention, since the first toy fixing and clamping mechanism 7 is movably arranged on the side of the support plate 3 facing away from the base 100, the support plate 3 is rotatably connected to the second support ring plate 2, and the second support ring plate 2 is rotatably connected to the first support ring plate 1. Therefore, the distance and position between the toy fixed by the first toy fixing and clamping mechanism 7 and the rotating mandrel 6 can be changed by the movement (displacement) of the first toy fixing and clamping mechanism 7. The angle between the rotating mandrel 6 and the toy fixed by the first toy fixing and clamping mechanism 7 in one direction can be changed by the rotation of the support plate 3 relative to the second support ring plate 2, and the angle between the rotating mandrel 6 and the toy fixed by the first toy fixing and clamping mechanism 7 in another direction can be changed by the rotation of the second support ring plate 2 relative to the first support ring plate 1. Thus, the relative positional relationship between the sharp edge of the toy fixed by the first toy fixing and clamping mechanism 7 and the measuring tape on the rotating mandrel 6 can be accurately adjusted, so that the sharp edge of the toy can be accurately pressed against the measuring tape on the rotating mandrel 6 at the required angle and orientation, improving the test efficiency and convenience of toy sharp edge detection.

[0059] According to a specific embodiment of the present application, the first rotating shaft 4 is perpendicular to the second rotating shaft 5, the support plate 3 is a circular plate, and the circular plate, the first support ring plate 1, and the second support ring plate 2 are arranged concentrically. One first rotating shaft 4 is fixedly connected to each of the radial two ends of the second support ring plate 2, and the axes of the first rotating shafts 4 are located on the same radial line of the second support ring plate 2. Each first rotating shaft 4 is rotatably connected to the inner ring side of the first support ring plate 1. One second rotating shaft 5 is fixedly connected to each of the radial two ends of the support plate 3, and the axes of the second rotating shafts 5 are located on the same radial line of the support plate 3. Each second rotating shaft 5 is rotatably connected to the inner ring side of the second support ring plate 2. The toy sharp edge detection device includes a first locking mechanism for fixing the first rotating shaft 4 to the first support ring plate 1 and a second locking mechanism for fixing the second rotating shaft 5 to the second support ring plate 2. Specifically, the first rotating shaft 4 has a section extending out of the outer ring side of the first support ring plate 1, and an external thread is formed on this section. The second rotating shaft 5 has a section extending out of the outer ring side of the second support ring plate 2, and an external thread is formed on this section. Both the first locking mechanism and the second locking mechanism can be locking nuts 8, and the locking nuts 8 are installed on the sections of the first rotating shaft 4 extending out of the outer ring side of the first support ring plate 1 and the sections of the second rotating shaft 5 extending out of the outer ring side of the second support ring plate 2 through thread fitting.

[0060] According to an embodiment of the present application, the toy sharp edge detection device includes an annular track 9 provided on the surface of the support plate 3 facing away from the base 100. The annular track 9 surrounds the rotating spindle 6, and the first toy fixing and clamping mechanism 7 is provided on the annular track 9 and can move along the annular track 9.

[0061] According to a preferred embodiment of the present application, the annular track 9 is a track portion of an electric guide rail. The electric guide rail mechanism further includes a slider portion 10 provided on the annular track 9. The first toy fixing and clamping mechanism 7 is detachably mounted on the slider portion 10. Of course, the annular track 9 can also be a pure mechanical structure. In this case, the first toy fixing and clamping mechanism 7 is manually operated to move along the annular track 9.

[0062] According to an embodiment of the present application, the number of rotating spindles 6 is multiple, for example, 4 rotating spindles 6 arranged at equal angular intervals such as 90°. The multiple rotating spindles 6 are parallel and spaced from each other. A driven gear 11 is provided on the section of the rotating spindle 6 located between the support plate 3 and the base 100. The heights of the driven gears 11 corresponding to the respective rotating spindles 6 are different. The rotation driving mechanism includes a motor 12 that is liftably provided on the base 100 and a driving gear 13 provided on the output shaft of the motor 12. When the motor 12 is lifted to different heights, it can be engaged with the driven gears 11 at different heights one by one. The output shaft of the motor 12 is parallel to the axis of the rotating spindle 6. The advantage of this embodiment is that by providing multiple rotating spindles 6 on the support plate 3, the measurement tapes are installed on the multiple rotating spindles 6 at one time, and there is no need to repeatedly clamp the toy to be tested and repeatedly replace the measurement tape. Only by moving the toy to be tested fixed by the first toy fixing and clamping mechanism 7 can the multiple sharp edges of the toy to be tested be quickly tested at one time. In addition, due to the different heights of the driven gears 11 corresponding to the respective rotating spindles 6, the corresponding rotating spindle 6 can be selectively driven to rotate by lifting the motor 12 to change the position height.

[0063] According to a specific embodiment of the present application, the toy sharp edge detection device includes a lifting guide rail 14 provided on a base 100. The upper surface 141 of the lifting guide rail 14 spirally ascends along a first circular arc trajectory. A motor 12 is movably provided on the lifting guide rail 14 along the lifting guide rail 14. When the motor 12 moves on the lifting guide rail 14, a driving gear 13 can move upward or downward along a second circular arc trajectory. The projection of the second circular arc trajectory around the axis of the rotation spindle 6 surrounds each rotation spindle 6. Specifically, a lifting sliding block 15 is installed on the lifting guide rail 14, and the motor 12 is installed on the lifting sliding block 15. The lifting sliding block 15 can be fixed to the lifting guide rail 14 by a first knob-type locking screw 16. Specifically, clamping plates 19 that sandwich the lifting guide rail 14 are connected to both sides below the lifting sliding block 15. The first knob-type locking screw 16 is arranged on the clamping plates 19 so that the clamping plates 19 can abut and press against the outer side of the lifting guide rail 14. In this way, when the lifting sliding block 15 spirally ascends or descends along the first circular arc trajectory, the driving gear 13 can gradually engage with the driven gear 11 along the superposition direction of the vertical direction and the horizontal arc direction, avoiding the impact phenomenon when the tooth positions are incorrect during meshing.

[0064] As another embodiment, the motor 12 can also be installed on the base 100 through mechanisms such as a lifting cylinder. At this time, the central axis of the driving gear 13 is located on the center line surrounded by a plurality of driven gears 11.

[0065] According to an embodiment of the present application, a circular guide groove 101 is formed on the base 100. A plurality of columns 200 are connected below the first support ring plate 1. The lower ends of the columns 200 form sliding heads 201 that cooperate with the circular guide groove 101. The columns 200 can move along the circular guide groove 101 to enable the first support ring plate 1 to rotate relative to the base 100. A locking structure for locking and fixing the lower end of the column 200 to the base 100 is also connected to the column 200. A flange plate 202 can be provided at the lower end of the column 200. The locking structure can be a second knob-type locking screw 17 that passes through the flange plate 202. The screw part of the second knob-type locking screw 17 can be pressed against the base 100 after being tightened, so that the first support ring plate 1 is locked to the base 100. After loosening, the first support ring plate 1 can adjust its position by rotating through the cooperation between the lower end of the column 200 and the circular guide groove 101.

[0066] According to a specific embodiment of the present application, the toy sharp edge detection device further includes a second toy fixing and clamping mechanism 18 disposed on the base 100 and on one side of the first support ring plate 1. The second toy fixing and clamping mechanism 18 can move to a position adjacent to the measuring tape fixed on the rotating spindle 6. The present application employs two toy fixing and clamping mechanisms, and it is possible to select whether to use the first toy fixing and clamping mechanism 7 or the second toy fixing and clamping mechanism 18 according to the size of the toy and other requirements, which increases the ability of the toy sharp edge detection device to adapt to products of more sizes. Both the first toy fixing and clamping mechanism 7 and the second toy fixing and clamping mechanism 18 can be automated electric control manipulators. The automated electric control manipulator includes a main machine 300 and a jaw part 301 that is telescopically and rotatably connected to the main machine 300.

[0074] S6, repeating steps S3 to S5 and making the target rotating spindle different each time, until the measuring tapes on all rotating spindles 6 are cut by the sharp edge of the toy to be tested, then removing each measuring tape and recording the cut length of each measuring tape for toy sharp edge analysis, such as calculating the percentage of the measuring tape length cut during the test, if the value is greater than 50% of the contact length, the edge to be tested is a sharp edge;

[0075] The second detection method comprises the steps of:
