Description

Technical Field

[0001] The present invention relates to the technical field of sensors, in particular to a modular photoelectric sensor. Background Art

[0002] Photoelectric sensors use photoelectric devices as conversion elements. They can be used to detect non-electrical quantities that directly cause changes in light intensity, such as light intensity, illuminance, radiation temperature measurement, and gas composition analysis. They can also be used to detect other non-electrical quantities that can be converted into changes in light intensity, such as part diameter, surface roughness, strain, displacement, vibration, velocity, acceleration, and object shape and operating status. Due to their non-contact, fast response, and reliable performance, photoelectric sensors are widely used in industrial automation devices and robotics.

[0003] Most existing photoelectric sensors are of an integrated structure, so when they are damaged or malfunction, they can only be discarded and replaced as a whole, which increases the cost of use for users. Summary of the Invention

DETAILED DESCRIPTION

[0037] The following embodiments will be described in detail with reference to the accompanying drawings. Similar or identical parts are denoted by the same reference numerals in the drawings or description. In actual applications, the shape, thickness, or height of each component may be enlarged or reduced. The various embodiments listed in the present invention are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. Any obvious modifications or changes made to the present invention do not depart from the spirit and scope of the present invention.

[0038] See also Figure 1 In one embodiment of the present application, a modular photoelectric sensor includes:

[0039] Sensor body 2;

[0040] An outer shell 1, wherein the outer shell 1 is a shell with a single-side opening;

[0041] an end cover 8 detachably connected to the opening side of the outer shell 1;

[0042] A base 3 is provided in the outer shell 1 and is used to mount the sensor body 2. The base 3 is slidably provided in the outer shell 1 and can move along the length direction of the outer shell 1.

[0043] A first connecting assembly, used for detachably connecting the base 3 and the outer shell 1;

[0044] The first connecting component is used for detachably connecting the base 3 and the sensor body 2 .

[0045] It can be understood that during actual use of the photoelectric sensor of this embodiment, since the base 3 and the outer shell 1 as well as the base 3 and the sensor body 2 are detachably connected through a connecting assembly, when the sensor fails or is damaged, the end cover 8 can be opened, and the sensor body 2 together with the base 3 can be removed from the outer shell 1, and then the sensor body 2 can be removed from the base 3. In this way, the outer shell 1, the sensor body 2 and the base 3 can be inspected and repaired separately. If a component is damaged, it can be directly replaced without discarding the entire component, thereby reducing the cost of use.

[0046] In one case of this embodiment, a plurality of vertical plates 4 equidistantly arranged along the circumferential direction are fixed to the edge of the end face of the base 3 facing the opening of the outer shell 1, and a slide groove 51 is provided on the vertical plate 4. A plurality of slide bars 52 corresponding to the slide groove 51 are fixed on the inner wall of the outer shell 1, and the slide bars 52 are slidably connected to the slide groove 51, thereby realizing a sliding connection between the base 3 and the outer shell 1.

[0047] It should be noted that, in other cases, other sliding connection structures may be used between the base 3 and the outer shell 1 , which will not be described in detail here.

[0048] See also Figure 1-3 In one embodiment of the present application, the first connecting assembly includes a rotating seat 71, a hook 72 and a thrust spring 74;

[0049] The rotating seat 71 is a hollow structure with a single-sided opening. A flange 711 is provided on the open side of the rotating seat 71. The flange 711 has a plurality of notches 712. A plurality of hooks 72 are provided, each corresponding to the notches 712. The width of the hooks 72 is smaller than the width of the notches 712. A rotating shaft 75 is fixed to the side of the rotating seat 71 away from the base 3. The rotating shaft 75 extends out of the outer shell 1 and is rotatably connected to the outer shell 1. An operating handle 76 is fixed to the end of the rotating shaft 75.

[0050] Two ends of the thrust spring 74 are connected to the inner wall of the outer shell 1 and the outer wall of the base 3 respectively.

[0051] In one case of this embodiment, the contact surfaces between the rotating seat 71 and the hook 72 are evenly distributed with embedded holes, and balls 73 are arranged in the embedded holes.

[0052] When the locking cam 73 is in the unlock state, the locking cam 73 is in the unlock state, and the locking cam 73 is in the unlock state, so that the locking cam 73 is locked and the locking cam 73 is locked.

[0053] It should be noted that, in other embodiments, the first connecting component may also adopt other structures, as long as the base 3 and the outer shell 1 are detachably connected, which will not be elaborated here.

[0054] See also Figure 1 、 4 -5. In one embodiment of the present application, the second connecting assembly includes a fastening sleeve 61 and a connecting seat 62;

[0055] The connecting seat 62 is fixed on the side of the base 3 close to the sensor body 2, and the connecting seat 62 is composed of a threaded column 621 close to the base 3 and a plurality of elastic clips 622 away from the base 3; the fastening sleeve 61 is composed of a first cylinder 611 close to the base 3 and a second cylinder 612 away from the base 3. The inner wall of the first cylinder 611 is provided with an internal thread matching the threaded column 621, and the inner cavity surface of the second cylinder 612 is trumpet-shaped and its minimum inner diameter is smaller than the outer diameter of the sensor body 2.

[0056] It can be understood that during actual use of the photoelectric sensor in this embodiment, the fastening sleeve 61 is sleeved on the periphery of the connecting seat 62 and then the fastening sleeve 61 is rotated. Under the action of the threaded connection, the first cylinder 611 is screwed in the direction close to the base 3. After being screwed in to a certain position, the inner wall of the second cylinder 612 contacts the elastic clip 622, thereby pressing the elastic clip 622 against the periphery of the sensor body 2, and then fixing the sensor body 2 on the base 3. When the sensor body 2 needs to be removed from the base 3, it is only necessary to rotate the fastening sleeve 61 in the opposite direction to disengage the elastic clip 622 from the sensor body 2. The operation is also very convenient.

[0057] It should be noted that, in other embodiments, the second connecting component may also adopt other structures, as long as it satisfies the detachable connection relationship between the sensor body 2 and the base 3, which will not be elaborated here.

[0058] See also Figure 1 and Figure 6 In one embodiment of the present application, the end cover 8 has a protrusion, which extends into the inner cavity of the outer shell 1, and is provided with symmetrically distributed slots 81;

[0059] An installation groove 87 is provided on the inner wall of the outer shell 1 at a position corresponding to the card slot 81. The bottom of the installation groove 87 is connected to a card block 82 that cooperates with the card slot 81 through a connecting spring 83. The card block 82 is made of magnetic material. An electromagnetic block 84 is also installed at the bottom of the installation groove 87. When the electromagnetic block 84 is energized, the card block 82 is adsorbed by the electromagnetic block 84 and exits the card slot 81.

[0060] In one case of this embodiment, a touch switch 85 connected to the electromagnetic block 84 with wires is installed on the outer wall of the outer shell 1, and a touch rod 86 is fixed to the periphery of the operating handle 76. When the operating handle 76 is rotated to a position where the notch 712 is aligned with the hook 72, the touch rod 86 contacts the touch switch 85.

[0061] It can be understood that during actual use of the photoelectric sensor in this embodiment, under normal circumstances, the card block 82 is inserted into the card slot 81 under the resistance of the connecting spring 83, thereby completing the connection between the end cover 8 and the outer shell 1. When the end cover 8 needs to be opened, it is only necessary to energize the electromagnetic block 84. When the first connecting component in the above embodiment is adopted, when the operating handle 76 is rotated to the position where the notch 712 is aligned with the hook 72, the touch rod 86 contacts the touch switch 85, thereby energizing the electromagnetic block 84, so that the fixed relationship between the outer shell 1 and the base 3 and the outer shell 1 and the end cover 8 is released at the same time, which is more convenient to operate.

[0062] See also Figure 1 and Figure 7 , in one embodiment of the present application, the photoelectric sensor further comprises a bracket assembly for mounting the sensor on a device;

[0063] The bracket assembly includes a first support 91 fixed to the outer shell 1 and a second support 92 fixed to the device. The first support 91 and the second support 92 are connected by a locking mechanism.

[0064] In one aspect of this embodiment, the locking mechanism includes a connecting groove 911 formed in the first support 91 and a connecting rod 93 matched with the connecting groove 911;

[0065] A first slide 94 is fixed to the end of the connecting rod 93, and the first slide 94 is slidably clamped in an inverted T-shaped hole 921 opened in the second support 92; a fastening sleeve 95 is fixed on the inner wall of the inverted T-shaped hole 921, which is spaced apart from the first slide 94, and the fastening sleeve 95 and the first slide 94 are connected by a reset spring 96; a second slide 98 is slidably clamped in the horizontal hole body of the inverted T-shaped hole 921, and the second slide 98 and the first slide 94 are connected by a traction rope 97; an operating screw 99 is rotatably connected to the outer side of the second slide 98, and the operating screw 99 extends out of the second support 92 and is threadedly connected to the second support 92, and a turntable 991 is also fixed to the end of the operating screw 99.

[0066] It can be understood that during actual use of the photoelectric sensor in this embodiment, under normal circumstances, the connecting rod 93 is stuck in the connecting groove 911 under the resistance of the return spring 96, thereby completing the fixation between the first support 91 and the second support 92. When the entire sensor needs to be disassembled, the turntable 991 is used to drive the operating screw 99 to rotate, and the operating screw 99 drives the second slide 98 to move toward the outside under the action of the threaded connection. During the movement, the second slide 98 drives the first slide 94 to move through the traction rope 97, so that the connecting rod 93 moves in the direction away from the connecting groove 911 and finally disengages from the connecting groove 911, releasing the fixation between the first support 91 and the second support 92.

[0067] Of course, in other embodiments, the locking mechanism may also have other structures, which will not be described here.

[0068] In summary, the modular photoelectric sensor provided in the embodiment of the present application realizes a detachable connection between the outer shell 1 and the base 3, as well as between the base 3 and the sensor body 2, by setting a first connecting component and a second connecting component, thereby modularizing the overall photoelectric sensor. In this way, when the sensor fails, the outer shell 1, the sensor body 2 and the base 3 can be inspected and repaired separately. If a component is damaged, the component can be directly replaced without discarding the entire component, thereby reducing the cost of use. At the same time, the embodiment of the present application also provides a first connecting component and a first connecting component with an optimized structure, making the entire disassembly operation simple and quick.
