Description

Technical Field

[0001] The utility model belongs to the field of surface detection, and in particular relates to a light source device for surface detection. Background Art

[0002] After the toys are produced, the surface of the toys needs to be inspected for quality and unqualified products need to be eliminated. Currently, there are manual quality inspection and machine quality inspection. In some smaller toy factories, manual quality inspection is more often used to inspect the quality of toys. When inspecting toys, a detection light source device is required (to facilitate the observation of surface defects of the toys).

[0003] The existing detection light source device has only one light source, and when inspecting toys of different colors, light sources of different colors need to be used (using corresponding light sources of different colors can enhance the characteristics of the object surface and improve the contrast, thereby making it easier to detect surface defects. For example, for a blue object, a yellow light source should be selected for detection, and for a red object, a green light source should be selected for detection). Under the existing technology, in order to obtain different light sources, the light bulb needs to be replaced. On the one hand, it takes more time to replace the light bulb back and forth, which reduces production efficiency. On the other hand, the light bulb is fragile. When replacing it back and forth, it is easy for the light bulb to fall or collide, which can easily cause damage to the light bulb. Therefore, a technical measure is proposed to solve the problem that in order to obtain different light sources under the existing technology, the light bulb needs to be replaced. It takes more time to replace the light bulb back and forth, which reduces production efficiency. The light bulb is fragile. When replacing it back and forth, it is easy for the light bulb to fall or collide, which can easily cause damage to the light bulb. Utility Model Content

The bulbs are fragile and can easily fall or collide when replaced, which can easily cause damage to the bulbs.

[0006] (2) Technical solution

[0007] In order to solve the above technical problems, the utility model provides a light source device for surface detection, including a workbench and a vertical plate, a connecting plate is connected to the middle position of the side of the workbench, the end of the connecting plate away from the workbench is fixedly connected to the lower end of the vertical plate, a limiting groove is provided in the vertical plate, the limiting groove is close to the upper part of the vertical plate, the limiting groove is slidably connected to a lifting plate, and a rotating assembly is installed inside the end of the lifting plate away from the vertical plate. Thanks to the arrangement of the rotating assembly and multiple groups of lamp holders, when surface detection is performed on toys of different colors, the lamp holder is driven to rotate by the rotating assembly to achieve switching of different light sources, and there is no need to replace the bulbs back and forth.

The threaded connection between the screw rod and the vertical plate has a limiting effect on the screw rod, thereby ensuring that the lifting plate will not move downward, and rotating the rotating plate drives the lamp holder and the light bulb to move up and down.

[0017] By setting up a rotating component and multiple groups of lamp holders, when performing surface inspection on toys of different colors, the lamp holders are driven to rotate by the rotating component to switch between different light sources, and there is no need to replace the bulbs back and forth.

A lampshade 14 is movably installed on the lower surface of the lamp holder 8 through a thread, and a light bulb is movably installed inside the lampshade 14. The light sources of the light bulbs are different. When actually detecting surface defects on toys, the device is placed next to the conveyor belt, and then the distance between the lamp holder 8 and the workbench 1 is adjusted according to the size of the toy, and the rotating plate 10 is rotated. The rotation of the rotating plate 10 drives the screw 11 to rotate, and the screw 11 rotates and moves up and down along the vertical plate 6. The up and down movement of the screw 11 drives the lifting plate 13 to slide up and down along the limiting groove 12. When the lifting plate 13 moves up and down, it drives the rotating component 2, the connecting rod 7, the lamp holder 8 and the light bulb to move up and down. When the height of the light bulb and the toy is appropriate, stop rotating the rotating plate 10, and then use the rotating component 2 to adjust to the corresponding lamp holder 8 according to the color of the toy produced.

[0027] Working principle: When actually inspecting the surface defects of toys, place the device next to the conveyor belt (the conveyor belt is used to transport the toys that have been produced), and then adjust the distance between the lamp holder 8 and the toy according to the size of the toy (usually when toys are produced, the toys produced in a batch are the same, that is, only one type of toy needs to be inspected within a period of time). The specific method is to rotate the rotating plate 10, and the rotating plate 10 rotates to drive the screw 11 to rotate, and the screw 11 rotates and moves up and down along the vertical plate 6. The screw 11 moves up and down and drives the lifting plate 13 to slide up and down along the limiting groove 12. When the lifting plate 13 moves up and down, it drives the rotating component 2, the connecting rod 7, the lamp holder 8 and the light bulb to move up and down. When the height of the light bulb and the toy is appropriate, stop rotating the rotating plate 10. Through the arrangement of the rotating plate 10, the screw 11 and the lifting plate 13, it is convenient to adjust the distance between the light bulb and the toy according to the size of the toy, so that the light source can better illuminate the surface of the toy, so as to better perform surface inspection on the toy, and the screw 11 is threadedly connected to the vertical plate 6, which has a limiting effect on the screw 11, thereby ensuring that the lifting plate 13 will not move down;

[0028] Then, according to the color of the toy produced, the rotating assembly 2 is used to adjust to the corresponding lamp holder 8 (such as Figure 1There are four groups of lamp holders 8, which can be set to more or less lamp holders 8 as needed in practice), and the specific method is to rotate the knob 201, the knob 201 rotates to drive the round rod 202 to rotate, the round rod 202 rotates to drive the worm 203 to rotate, the worm 203 rotates to drive the limit rod 204 to rotate, the worm 203 rotates to drive the gear 205 to rotate, the gear 205 rotates to drive the vertical rod 206 to rotate, the vertical rod 206 rotates to drive the mounting plate 3 to rotate, the mounting plate 3 rotates to drive the connecting rod 7 to rotate, the connecting rod 7 rotates to drive the lamp holder 8 to rotate, and when the lamp holder 8 rotates, it drives the bulb to move to the upper surface of the workbench 1, and when it rotates to the bulb that matches the color of the toy, the knob 201 is stopped. By setting the rotating component 2 and multiple groups of lamp holders 8, when surface inspection is performed on toys of different colors, the lamp holder 8 is driven to rotate by the rotating component 2 to achieve switching of different light sources, and there is no need to replace the bulb back and forth.
