[0002] Industrial camera is a key component in machine vision system, and its most core function is to convert optical signal into orderly electrical signal. The lens of industrial camera cannot be easily contaminated, otherwise it will affect the observation accuracy, leading to misjudgment, so the industrial camera is often provided with shell for dustproof, waterproof and oil-proof protection. The shell serves as a protection mechanism and also as a fixing base for the industrial camera. The relative distance between the lens and the observed object needs to be considered for the industrial camera, so the relative position needs to be adjusted with the shell. However, the application of industrial camera may involve high temperature environment, such as in a hot press, and the industrial camera itself will also generate heat during operation. If the heat cannot be dissipated in advance, it will greatly affect the service life of the industrial camera.

[0023] The utility model will be further described in detail in combination with specific embodiments.

[0024] Embodiment:

[0025] As shown in Figure 1 and Figure 2 The utility model discloses an industrial camera installation protective cover suitable for high temperature occasions 100, including shell 1, adjusting seat 2, spring ring 3, a plurality of adjusting screw 4 and a plurality of fixed screw (not exposed).

[0026] As Figure 1 shown, the shell 1 comprises a front end cover 11, a sleeve 12 and a rear end cover 13 connected in sequence along the axial direction, the center of the front end cover 11 is provided with a light transmission lens 111 facing the lens 201 of the industrial camera 200, the front O-shaped sealing ring 14a is clamped between the front end cover 11 and the front end face of the sleeve 12, the center of the rear end cover 13 is provided with a cable locking head 131, the rear O-shaped sealing ring 14b is clamped between the rear end cover 13 and the rear end face of the sleeve 12, the front end cover 11, the sleeve 12 and the rear end cover 13 form a sealed space, and the adjusting seat 2 adjusts the position in the sealed space along the axial direction.

[0027] The shell 1 completely surrounds the industrial camera 200, and only the cable of the industrial camera 200 extends out from the cable locking head 131, so that the sealed space is separated from the outside, and therefore the shell 1 can provide waterproof, dustproof and oilproof protection for the industrial camera 200. The light transmission lens 111 can transmit the image of the observation direction to be received by the lens 201. The front end cover 11, the sleeve 12 and the rear end cover 13 are a kind of assembled structure, the front end cover 11 and the sleeve 12 are assembled together in advance, and the gap therebetween is sealed by the front O-shaped sealing ring 14a. After the industrial camera 200 is installed in the sleeve 12 and adjusted to the appropriate position, the rear end cover 13 is fixed to the rear of the sleeve 12, and the gap therebetween is sealed by the rear O-shaped sealing ring 14b. Then the cable locking head 131 is tightened to tightly hold the cable.

[0028] As Figures 2 to 4 shown, the adjusting seat 2 is cylindrical, has a hollow square hole 21 in the middle for fixing the industrial camera 200, has a ring groove 22 on the outer periphery for accommodating the spring ring 3, and has a plurality of rear threaded holes 23 on the rear part in the direction parallel to the axis of the adjusting seat 2, the inner end of the rear threaded hole 23 extends to the side wall of the ring groove 22, the outer diameter of the adjusting seat 2 matches the inner diameter of the sleeve 12 so that the adjusting seat 2 can move along the axial direction of the sleeve 12, the adjusting screw 4 penetrates into the rear threaded hole 23 and abuts against the spring ring 3 through the tip, and the spring ring 3 is forced to expand outwardly and abut against the inner wall of the sleeve 12. The adjusting seat 2 and the sleeve 12 are both made of aluminum alloy.

[0029] The adjusting seat 2 is first fixed as a whole with the industrial camera 200, and then the position relationship between the adjusting seat 2 and the sleeve 12 is adjusted. The spring ring 3 is elastic. When the adjusting screw 4 is loosened, the spring ring 3 will tightly embrace the inner wall of the ring groove 22, and the spring ring 3 is in a circular structure with an outer diameter smaller than that of the adjusting seat 2, at this time, the adjusting seat 2 is similar to a piston which can move axially in a sealed space; when the adjusting screw 4 is tightened, the adjusting screw 4 will press the spring ring 3, and the stressed part of the spring ring 3 will be flattened and widened, and then expand outward, but because the ring groove 22 faces the inner wall of the sleeve 12, the deformed part of the spring ring 3 will tightly adhere to the sleeve 12, thereby generating resistance to prevent the adjusting seat 2 from moving axially, so that the relative position between the industrial camera 200 and the sleeve 12 is fixed, and the installation and adjustment are convenient. In the embodiment, the rear threaded hole 23 is two, but can not be limited to two. The aluminum alloy has the advantages of low density and good thermal conductivity, there is a large contact area between the outer wall of the industrial camera 200 and the inner wall of the adjusting seat 2, and between the outer wall of the adjusting seat 2 and the inner wall of the sleeve 12, and the sleeve 12 in the shell 1 directly contacts with the adjusting seat 2, so only the easy heat dissipation of the adjusting seat 2 and the sleeve 12 is needed. The heat generated by the industrial camera 200 can be easily conducted to the sleeve 12 through the adjusting seat 2, and then dissipated to the outside through the sleeve 12, so that the rapid heat dissipation of the industrial camera 200 is ensured, and the damage of the industrial camera 200 caused by the heat accumulation in the sealed space is avoided, and the service life of the industrial camera 200 is ensured.

[0030] As shown in Figure 2 and Figure 3 , a plurality of threaded holes 24 are arranged on one side wall of the hollow square hole 21 of the adjusting seat 2, and the fixing screws pass through the threaded holes 24 and abut against the outer wall of the industrial camera 200 at the end.

[0031] The industrial camera 200 has a cuboid structure except the lens 201, and the cross section perpendicular to the optical axis direction is mostly square, so the adjusting seat 2 needs to accommodate the industrial camera 200 with the hollow square hole 21. However, it is difficult to avoid the gap between the industrial camera 200 and the hollow square hole 21, so that the industrial camera 200 can be easily put in. However, the industrial camera 200 needs to be fixed to avoid loosening, so the fixing screws passing through the threaded holes 24 are used to fix the adjusting seat 2 and the industrial camera 200. In the embodiment, the threaded holes 24 are three, but can not be limited to three. When the fixing screws are tightened, the end abuts against the outer wall of the industrial camera 200 (in the embodiment, the abutting surface is the lower surface of the outer wall of the industrial camera 200), so the opposite surface of the industrial camera 200 (in the embodiment, the upper surface of the outer wall of the industrial camera 200) will also abut against the hollow square hole 21. In this way, the heat generated on the industrial camera 200 can be more reliably conducted to the sleeve 12 through the side wall of the adjusting seat 2, and then dissipated. The fixing screws are embedded in the threaded holes 24, thereby avoiding interfering with the adjustment of the position of the adjusting seat 2 relative to the sleeve 12.

[0032] The above merely describes some embodiments of the present application. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are all within the protection scope of the present application.
