The creation system provides an assembly structure of an industrial camera, especially a separate structure of the lens holder and the housing, so that the housing does not need to develop different molds for different sensing elements of the camera module to replace different lenses. The lens holder of the hole size is assembled with the sensing element, thereby achieving the effects of stable structure, mass production, and lower cost.

According to the current trend of electronic technology, with the rapid development of software and hardware under the open architecture, the manufacturers have developed industrial computers suitable for various professional fields, mainly in applications such as Industrial control, industrial automation, metrology, network and communication equipment, machine vision and motion control, etc., can also be applied to applications requiring high reliability and stability in medical, defense, transportation and aerospace fields with important tasks. To meet the requirements of performing high-performance operations in specific specifications and harsh environments.

Furthermore, the application of machine vision in various industries has been in production for many years, and the use of machine vision to improve detection accuracy or accelerate production efficiency has gradually become an imaging device necessary for many production inspection equipment. With the continuous development of machine vision technology, it can also be applied to high-speed machine vision applications such as digital surveillance, video or 3D guided vision robots to meet the high resolution, high picture update rate and the transmission, processing and interpretation of large amounts of image data. Demand, and can increase the efficiency of testing output and reduce production costs.

The general machine vision inspection system includes an illumination source, a camera, an image processing device, a display screen, etc., wherein the industrial camera can be mainly divided into a face scan type and a line scan type, and the camera will project the lens through the lens. The image captured on the measuring component is transmitted to the image processing device for further interpretation, and then stored, analyzed or directly displayed on the screen, but the general camera is a detachable lens, and the lens is It is screwed into the lens mount of the housing. This can be used to remove the lens from the mounting hole of the lens mount for practical applications, and then replace the lens with different specifications to obtain higher resolution and best. Imaging quality, but because the size of the sensing component mounted on the internal circuit board of the camera is fixed with the lens hole of the lens holder, it cannot be replaced, and it is difficult to upgrade the hardware of the detection system or the entire camera must be replaced, so that the device The cost of updating and use becomes relatively high, and the lens mount and the housing are integrally formed, and if it is the lens hole of the lens mount In combination with different size sensing components, it is necessary to develop different molds for the housing to produce, resulting in a large number of molds and the cost can not be effectively reduced. Therefore, how to effectively solve the problem that the lens holder and the housing are integrally formed However, the problem that the number of molds derived from the assembly of sensing elements of different sizes is increased and the cost is high has been regarded as a problem to be solved by the industry, and it is yet to be redesigned to effectively solve the problem.

Therefore, in view of the above-mentioned problems and shortcomings, the new creators have collected and collected relevant materials through various evaluations and considerations, and have used the trial and modification of many years of R&D experience in this industry to design such industrial cameras.

The lens holder has a simple assembly structure and an easy mold design, and the assembly of the sensing element and the lens hole is facilitated after assembly, and the lens is assembled. The housing and the housing are separated from each other, so that the housing does not need to develop different molds for different sensing elements of the camera module, and only the lens holders with different lens hole sizes are required to be assembled with the sensing elements. Conducive to modular mass production, it can also simplify the process and the number of molds, so as to achieve structural stability, mass production and lower cost.

The secondary purpose of the present invention is that a plurality of heat conducting blocks positioned on the circuit board are disposed around the sensing component of the camera module. When the sensing component of the camera module is in operation, the sensing block can absorb the sensing through the heat conducting block. The heat generated by the component and the heat is transmitted to the housing through the lens holder to form a heat conduction path, and the heat conduction block is brought into contact with the sensing element to form a direct heat transfer function, and the lens holder and the shell are utilized. The body further increases its overall heat dissipation area to improve the heat dissipation efficiency of the sensing element and maintain the normal operation of the overall system.

Another object of the present invention is that a lens surface of the lens holder is formed with a blocking surface adjacent to the longitudinal surface of the mounting hole, and a light absorbing layer is formed on the blocking surface. When the sensing element of the camera module is in operation, The measuring component senses the predetermined lens combined in the mounting hole of the lens holder to focus the projected light, and in the process of sensing the sensing component, the light absorption layer can also absorb the non-image information light incident on the lens hole to effectively Suppressing the sensing element may sense the noise generated by the light, thereby ensuring the quality of the image capture.
