Description

Technical Field

[0001] The utility model relates to the technical field of laser marking, in particular to a defrosting structure and a laser marking device. Background Art

[0002] Some products are stored in a low-temperature environment. When taken out of the low-temperature environment for marking, it is necessary to remove the frost formed by sublimation on the product, otherwise it will affect the marking. For example, when the product to be marked is a cryotube, since the cryotube stores gene samples, it can only be stored in an environment below -80 degrees Celsius. When the cryotube is taken from an environment of -80 degrees Celsius to a room temperature environment, due to the sublimation phenomenon, water molecules in the air will form a layer of white frost on the surface of the cryotube. This layer of white frost will affect the selection of the marking position of the cryotube. Due to the characteristics of the sample, the cryotube cannot be placed at a temperature above zero for a long time for natural defrosting, otherwise the sample will lose its activity. In the prior art, most of them are manually assisted to wipe off the white frost, but this method has a large workload and a very poor defrosting effect, affecting the production efficiency.

Detailed Embodiments

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figure 1 and Figure 2, an embodiment of the present utility model provides a defrosting structure, which includes a material taking component 1 that can grasp and rotate a product 6 and a blowing component 2 for blowing air towards the product 6, and the orientation of the air blowing port of the blowing component 2 is adjustable. In this embodiment, the material taking component 1 during laser marking is utilized to grasp and rotate the product 6, and then cooperate with the blowing component 2 to blow air towards the product 6. Since the orientation of the air blowing port is adjustable, the blown air can be directly aimed at the product 6, and the product 6 can complete the removal of white frost after rotating a few circles, improving the defrosting efficiency. Specifically, the main function of the material taking component 1 is used during the laser marking process to grasp and rotate the product 6 to facilitate the edge finding component 4 to find the marking position of the product 6. When used in the defrosting structure, its rotating function can be utilized to drive the product 6 to rotate, improving the defrosting efficiency of the blowing component 2. At the same time, since the orientation of the air blowing port is adjustable, when facing products 6 of different specifications, the position of the air blowing port can be adjusted to ensure that the blown air can be aligned with the product 6, further improving the defrosting efficiency. The product 6 described in this embodiment is a cryotube.

[0021] To refine the above blowing component 2, please refer to Figure 1 and Figure 2 , the blowing component 2 includes a blower 20 and a driving member 21 that drives the blower 20 to rotate to adjust the position of the air blowing port. In this embodiment, blowing is performed by the blower 20. The blower 20 can be selected as a cold air blower to blow high-speed cold air to improve the defrosting efficiency. The rotation speed of the blower 20 can be selected between 10000 and 12000 rpm, so that the white frost can be removed basically after rotating one or two circles. The driving member 21 that drives the air blowing port to adjust the position, such as a rotating motor, or other existing driving rotation methods can be used. This embodiment does not limit this. Preferably, the blowing component 2 further includes a bracket 22, and both the blower 20 and the driving member 21 are installed on the bracket 22. Through the designed bracket 22, the blower 20 and the driving member 21 can be erected. Usually, the product 6 taken out by the material taking component 1 is suspended in the air. Using the bracket 22 to erect the blower 20 can make the cold air blown out by the blower 20 closer to the product 6, improving the defrosting efficiency. When the clamping component clamps multiple products 6 at a time, or when it is desired to accelerate the defrosting efficiency, multiple blowers 20 can be used in combination. Multiple blowers 20 can be fixed together by a fixing frame 23 to form a module, and then the driving member 21 can be used to drive the fixing frame 23 to rotate to control the rotation of multiple blowers 20.

Through the edge finding component 4, the marking position of the product 6 can be found for marking. When used in combination with the above-mentioned defrosting structure, first, the jaw 10 grasps the product 6 and reaches the marking position, then the jaw 10 drives the product 6 to rotate. During the rotation, the defrosting structure defrosts the product 6. After defrosting, the camera 40 triggers to take a picture, and the jaw 10 continues to drive the product 6 to rotate for edge finding operation, where the light source 41 provides light to reduce the edge finding difficulty. How to find the edge is described in detail in the above-mentioned published document. The applicant has explained in detail before and will not repeat here.
