Description

Technical Field

[0001] The utility model relates to the technical field of automated production equipment, in particular to a bottom camera alignment mechanism of a dispensing device. Background Art

[0002] In automatic dispensing equipment, in order to meet the requirements of fast and accurate positioning and identification of products, a visual alignment mechanism is generally used to obtain the image of the product, and the returned image information is identified through the control system, so that the dispensing head can perform dispensing processing on the product. However, the relevant product alignment mechanisms in the equipment currently on the market are generally fixed above or below the product, and the product is identified and judged from a fixed distance. In this way, in the process of identifying products of different specifications and sizes, due to the different specifications and sizes of the products, when the image of the product is acquired, due to the differences in some features on each product, in order to ensure the acquisition of clear and recognizable images, it is generally necessary to adjust the focal length of the alignment mechanism. Different CCD cameras have different adjustable focal length ranges. In the dispensing machine equipment, in order to save the setting space, avoid interference with the dispensing position, and avoid collision with other mechanisms, a relatively small CCD camera is generally selected as the alignment mechanism. However, the adjustable focal length range of small-sized CCD cameras is small, and it is not well adapted to the characteristics of different products and the focal length is effectively adjusted to obtain a clear image, which is inconvenient.

[0003] Therefore, the prior art has defects and needs to be improved. Utility Model Content

[0004] The utility model aims to overcome the deficiencies of the prior art and provide a bottom camera alignment mechanism for a dispensing device.

[0005] The technical solution of the utility model is as follows: a bottom camera alignment mechanism of a dispensing device is provided, comprising: a loading platform, a Z-axis moving module arranged below the loading platform, a motion bracket arranged on the moving end of the Z-axis moving module, a CCD bracket arranged on the motion bracket, and a CCD camera arranged on the CCD bracket, wherein a plurality of mounting holes are arranged on the side of the CCD camera, and a plurality of strip holes are arranged corresponding to the mounting holes of the CCD camera, and the strip holes are arranged along an up and down direction.

[0006] Furthermore, a sub-plate is arranged on the side of the CCD bracket, and the sub-plate and the CCD bracket are at right angles to surround the outside of the CCD camera. A plurality of holes are arranged on the sub-plate corresponding to the CCD camera.

[0007] Furthermore, a light source is arranged on the top of the CCD bracket corresponding to the lens direction of the CCD camera.

[0008] Furthermore, a glue gun head is arranged on the moving bracket.

[0009] Furthermore, a vacuum generator is provided on the loading platform, and adsorption holes are provided on the surface of the loading platform.

[0010] Furthermore, an FPC support plate is provided at one end of the loading platform.

[0011] Furthermore, an observation port is provided between the loading platform and the FPC support plate.

[0012] By adopting the above scheme, the utility model directly adjusts the Z-axis position of the CCD camera through the Z-axis moving module, or changes the position of the CCD camera on the Z-axis by adjusting the relative position of the CCD camera locked on the bar hole, thereby adjusting the focusing position of the CCD camera to meet the focusing requirements of different products, thereby obtaining a clear image, and facilitating the control system to quickly identify and locate the position status of the product.

[0015] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0016] See also Figure 1 , Figure 2 The utility model provides a bottom camera alignment mechanism of a dispensing device, comprising: a loading platform 1, a Z-axis moving module 2 arranged below the loading platform 1, a moving bracket 21 arranged on the moving end of the Z-axis moving module 2, a CCD bracket 3 arranged on the moving bracket 21, and a CCD camera 4 arranged on the CCD bracket 3, wherein a plurality of mounting holes are arranged on the side of the CCD camera 4, and a plurality of strip holes 31 are arranged corresponding to the mounting holes of the CCD camera 4, and the strip holes 31 are arranged along the up and down direction.

[0017] During operation, a locking member, such as a screw, is passed through the bar hole and locked in the mounting hole on the side of the CCD camera 4, thereby fixing the CCD camera 4 on the CCD bracket 3. When it is necessary to adjust the focal length of the CCD camera 4 according to the product to be dispensed, the Z-axis position of the CCD camera 4 can be directly adjusted through the Z-axis moving module 2, or the relative position of the CCD camera 4 locked on the bar hole 31 can be adjusted to change the position of the CCD camera 4 on the Z-axis, thereby adjusting the focus position of the CCD camera 4 to meet the focus requirements of different products, thereby obtaining a clear image, and facilitating the control system to quickly identify and locate the position status of the product.

[0018] In some embodiments, a sub-plate 32 is provided on the side of the CCD bracket 3, and the sub-plate 32 and the CCD bracket 3 are at right angles to surround the outside of the CCD camera 4, and a plurality of holes are provided on the sub-plate corresponding to the CCD camera 4. The sub-plate 32 and the CCD bracket 3 provide support and connection for the CCD camera 4 from both sides at the same time, thereby facilitating the improvement of the stability of the CCD camera 4 when adjusting through the holes 31, and ensuring that the recording center line of the camera head of the CCD camera 4 is located on the vertical line after being locked and fixed, thereby ensuring the effect of the CCD camera 4 shooting the product on the loading platform 1.

[0019] In some embodiments, a light source 5 is provided on the top of the CCD bracket 3 corresponding to the lens direction of the CCD camera 4. The light source 5 illuminates the product, so that the image captured by the CCD camera 4 is clearer, which facilitates the CCD camera 4 to capture product features and ensures the CCD camera 4 captures the product image effectively.

[0020] In some embodiments, a glue gun head 6 is provided on the motion bracket 21, which facilitates the movement of the glue gun head in the Z-axis direction through the Z-axis moving module 2 to meet the needs of the glue dispensing work, and the CCD camera 4 is integrated with the Z-axis moving drive of the glue gun head 6 to reduce the number of mechanisms in the overall equipment, thereby reducing the space occupied.

[0021] In some embodiments, a vacuum generator 11 is provided on the carrier platform 1, and adsorption holes 12 are provided on the surface of the carrier platform 1. The vacuum generator 11 and the adsorption holes 12 are connected through a pipeline. When the vacuum generator 11 is started, negative pressure suction is generated at the adsorption holes 12, thereby adsorbing the product on the carrier platform 1, which is convenient for processing operations such as gluing on the product.

[0022] In some embodiments, an FPC support plate 13 is provided at one end of the loading platform 1 to support the FPC in front of the product. An observation port 14 is provided between the loading platform 1 and the FPC support plate 13 to facilitate the CCD camera 4 to obtain a characteristic image of the product through the observation port 14 while supporting the FPC.
