Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without any creative work fall within the protection scope of the utility model.

[0020] Please refer to Figure 1 The utility model provides a kind of irregular UV printer with visual scanning positioning technical scheme: a kind of irregular UV printer with visual scanning positioning, including body 1, the upper end of body 1 two sides symmetry is equipped with Y axis linear module 3, two Y axis linear module 3 are jointly connected with X axis linear module 4, X axis linear module 4 is equipped with UV printing mechanism 5, two Y axis linear module 3 jointly drive X axis linear module 4 and UV printing mechanism 5 and visual inspection equipment 2 are moved in Y axis linear on body 1, and X axis linear module 4 can drive UV printing mechanism 5 and visual inspection equipment 2 are moved in X axis linear on body 1, so as to can adjust the position of UV printing mechanism 5 and visual inspection equipment 2 in X axis and Y axis direction.

[0021] As Figure 2 As shown in the figure, the upper end of body 1 is equipped with a plurality of positioning mechanisms 6 in parallel in the middle, and the positioning mechanism 6 includes a mounting seat 61 and a plurality of turnover seats 62 arranged inside the mounting seat 61. A turnover motor 63 is arranged on one side of the mounting seat 61 corresponding to each turnover seat 62. The output end of the turnover motor 63 is fixed to one end of the turnover seat 62 through the mounting seat 61. The turnover seat 62 and the mounting seat 61 are rotationally connected. By controlling the forward or reverse rotation of the turnover motor 63, the turnover seat 62 can be driven to rotate forward or reverse inside the mounting seat 61. For example, when the turnover motor 63 rotates forward, it can drive the turnover seat 62 to rotate forward by 90 degrees, so as to turn the side (i.e. the left side) of the model product on the turnover seat 62 upward (i.e. in the direction of the UV printing mechanism 5). Conversely, when it rotates in reverse, it can drive the turnover seat 62 to rotate reverse by 90 degrees, so as to turn the other side (i.e. the right side) of the model product upward.

[0022] A plurality of rotating rods 65 are equidistantly arranged on the turnover seat 62, each rotating rod 65 penetrates the top and bottom of the turnover seat 62, the top end of the rotating rod 65 is connected with a negative pressure suction cup 69, the bottom end of the rotating rod 65 is connected with a negative pressure suction pipe 68, the rotating rod 65 is a hollow structure, one end of the negative pressure suction pipe 68 is connected with the negative pressure suction cup 69 through the rotating rod 65, the other end of the plurality of negative pressure suction pipes 68 is commonly connected with a vacuum pump through a hose, when the model product to be printed is placed on the negative pressure suction cup 69, the vacuum pump is used to vacuum the inside of the negative pressure suction cup 69 to generate negative pressure, so that the negative pressure suction cup 69 can conveniently adsorb and fix the product, and the operation is simple, and the product can be quickly positioned. It should be noted that the plurality of negative pressure suction cups 69 on each mounting seat 61 can share one vacuum pump, and the connected hose has stretching and bending properties, which does not affect the vacuuming operation of the negative pressure suction pipe 68 when the turnover seat 62 is turned over.

[0023] The plurality of rotating rods 65 on each turnover seat 62 are connected through a transmission mechanism, the transmission mechanism includes two belt rollers 66 mounted at the lower end of each rotating rod 65, and each two rotating rods 65 are drivingly connected through a transmission belt 67 and the belt rollers 66. The rotating rod 65 is connected with the turnover seat 62 through a bearing. The transmission mechanism further includes a hollow shaft motor 64 mounted at the lower end of the turnover seat 62. The lower end of one of the rotating rods 65 on the turnover seat 62 penetrates the hollow shaft of the hollow shaft motor 64 and is fixedly connected with the hollow shaft. The hollow shaft motor 64 can drive one of the rotating rods 65 on the turnover seat 62 to rotate. In combination with the connection of the transmission mechanism, the plurality of rotating rods 65 on the turnover seat 62 can be synchronously rotated. In this way, the plurality of products on the turnover seat 62 can be synchronously rotated in the horizontal direction to adjust the angle of the product. In combination with the above-mentioned turnover motor 63 driving the turnover seat 62 to turn over, the front end face and the rear end face of the product can be turned over to face upwards and correspond to the UV printing mechanism 5, so as to facilitate the printing operation of the front end face and the rear end face of the product.

[0024] A visual detection device 2 is arranged at the side of the lower end of the UV printing mechanism 5 close to the printing head. The visual detection device 2 adopts an existing visual scanning system, which includes:

[0025] a CCD camera for capturing images or videos of workpieces;

[0026] a light source for illuminating the surface of the workpiece to ensure that the camera can obtain clear and uniform images;

[0027] an image processing unit for receiving image data collected by the camera and performing processing, analysis and judgment, which can specifically adopt an image processor;

[0028] Optical sensors, such as laser sensors or reflective sensors, for real-time monitoring of the height, inclination, surface defects, and other characteristics of the workpiece, helping to ensure accurate positioning of the workpiece during printing.

[0029] Control chips for managing and scheduling hardware devices such as cameras, sensors, and light sources.

[0030] The working principle of the utility model is as follows: in actual application, the products to be printed are placed on the negative pressure suction cups 69, and the negative pressure suction cups 69 generate negative pressure suction force to firmly adsorb the products.

[0032] Then, the UV printing mechanism 5 is controlled to print on the top of the product according to the product data information obtained by the vision detection device 2.

[0034] Further, the hollow shaft motor 64 can be controlled to rotate forward or backward, so that it can drive the multiple rotating rods 65 on the rotation seat 62 to rotate synchronously, thereby synchronously controlling the multiple products on the rotation seat 62 to rotate synchronously to adjust the angle of the product, facilitate the scanning and identification of the front and back surfaces of the product by the vision detection device 2, facilitate the acquisition of the data information of the front and back surfaces of the product, and facilitate the printing of the UV printing mechanism 5 on the front and back surfaces of the product.

[0035] The irregular objects such as mobile phone cases, toys, and models can be quickly fixed by negative pressure adsorption, and the multi-angle rotation adjustment can facilitate the vision detection device 2 to obtain the multi-surface data information of the product to be printed, ensure the accuracy of the UV printing mechanism 5, realize integrated synchronous printing, automatic identification, save printing time, save cost, improve efficiency, have a wide application range, and have high automation degree.
