TECHNICAL FIELD

[0001] The application relates to the technical field of a scribe line detection device, in particular to a full-automatic da Vinci pen scribe line detection device. BACKGROUND

[0002] The existing da Vinci pen available on the market is mainly used for surface tension test of a coating, paint or plastic surface, and the surface tension test pen is vertically placed on the surface of the material to be tested, and a straight line is formed on the surface, if the straight line can be maintained continuously within 2s-4s without shrinkage, the surface tension of the object reaches the tension value of the test pen, if the straight line is discontinuous within 2s-4s and condenses into small water droplets, the product does not reach the tension value of the test pen.

[0003] Because the effective time for judgment is short (2s-4s), and the scribe force and other factors are greatly affected by human factors, the judgment result is different for different people, and misjudgment may occur, thereby affecting the detection result, and improvement is needed. CONTENT OF THE UTILITY MODEL

[0004] The application aims to provide a full-automatic da Vinci pen scribe line detection device to improve the detection result of the surface tension of a product.

[0007] By adopting the above technical scheme, the product to be tested is placed on the placing plate, the driving mechanism drives the da Vinci pen to slide, the contact end of the da Vinci pen scribes a line on the surface of the product, after scribing the line, the camera completes the first photographing within 30ms, the camera completes the second photographing within 2s-4s, and the external device automatically compares the area proportion of the scribe line area in the first photo and the second photo, so as to judge whether the product is qualified. The driving mechanism can make the da Vinci pen move at the same speed, and the scribe force of the da Vinci pen on the product to be tested is also equal, thereby improving the detection result of the surface tension of the product.

[0008] Optionally, the placing plate is provided with a placing groove used for cooperating with the product.

[0009] By adopting the technical scheme, the product is placed in the placing groove, and the outer surface of the product is attached to the inner wall of the placing groove. When the daubing pen moves, the daubing pen exerts force on the product, and the inner wall of the placing groove limits the movement of the product, thereby improving the stability of the product placed on the placing plate.

[0010] Optionally, the bottom plate is slidably connected with a carrier plate and a sliding assembly, the sliding assembly is used to drive the carrier plate to slide towards the direction of approaching or moving away from the daubing pen, and the placing plate is connected with the carrier plate.

[0011] By adopting the technical scheme, the sliding assembly drives the carrier plate to slide towards the direction of moving away from the daubing pen, that is, the placing plate slides towards the direction of moving away from the daubing pen, so that the placing plate moves to the open area, and the product is convenient to take and place.

[0014] Optionally, the bottom plate is detachably connected with a mounting plate, the bottom plate is threadedly connected with a locking piece, the mounting plate is provided with a waist-shaped hole for the locking piece to pass through, and the pen cap is connected to the mounting plate.

[0020] Optionally, the rotating plate is threadedly connected with a first fixing member, and the lifting plate is provided with a first arc-shaped slot for rotationally cooperating with the first fixing member.

[0021] By adopting the above technical scheme, when the rotating plate rotates, the rotation of the first fixing member and the first arc-shaped slot serves as a guide and a position limiter for the rotation of the rotating plate, thereby improving the stability of the rotation of the rotating plate. When the rotating plate rotates to a corresponding position, the first fixing member is rotated towards the direction close to the lifting plate, so that the first fixing member abuts against the lifting plate, thereby improving the stability of the fixing of the rotating plate on the lifting plate.

[0022] Optionally, the rotating plate is provided with a through hole for the daoyin pen to pass through, and the rotating plate is connected with a clamping assembly for limiting the movement of the daoyin pen.

[0023] By adopting the above technical scheme, the daoyin pen slides along the through hole to adjust the height of the daoyin pen, so that the daoyin pen is suitable for products of different thicknesses.

[0024] Optionally, the clamping assembly comprises a driving member and two clamping blocks which are spaced apart on the rotating plate, a gap is formed between the two clamping blocks, the through hole is formed between the two clamping blocks, the gap is in communication with the through hole, and the driving member is connected to the clamping blocks, and the driving member is used to drive the two clamping blocks to move towards each other away from one end of the rotating plate.

[0025] By adopting the above technical scheme, when the daoyin pen moves to a corresponding height, the driving member drives the two clamping blocks to move towards each other away from one end of the rotating plate, so that the inner wall of the through hole clamps the daoyin pen, and the daoyin pen is fixed between the two clamping blocks.

[0027] 1. The driving mechanism can make the daoyin pen move at the same speed, and the daoyin pen has the same line drawing force on the product to be tested, thereby improving the result of the product surface tension detection.
