Description

Technical Field

[0001] The present application relates to the technical field of through-beam sensor testing, and in particular to a photoelectric sensor pairing test fixture. Background Art

[0002] With the rapid development of optoelectronic technology, photoelectric sensors are increasingly used in various industries. In the production process of photoelectric sensors, a pair of transmitting and receiving sensors need to be paired (core-aligned) for testing. If they cannot be paired, it means that the transmitter or receiver of the sensor is installed in an offset position.

[0003] At present, the paired sensors detected by the existing test fixtures cannot be applied to some devices that have strict requirements on the size of the emission spot. For example, if only a small hole with a diameter of 2mm is opened on the device, it will make it difficult to ensure the alignment of the transmitting and receiving sensors. Utility Model Content

[0004] In order to overcome at least some of the defects and shortcomings in the prior art, the present application provides a photoelectric sensor pairing test fixture, and the paired sensors can be suitable for devices with relatively strict requirements on the spot size to ensure the alignment of the transmitting and receiving sensors.

[0015] By adopting the above technical solution, the provision of the first magnetic attraction member can facilitate the magnetic attraction fixation of the first fixing frame and the second fixing frame, so as to facilitate the fixation and disassembly of the first fixing frame and the second fixing frame.

[0016] Optionally, a second magnetic component is further provided on the side surfaces of the first product component and the second product component, and the first fixing frame and the second fixing frame are magnetically fixed to the first product component and the second product component respectively via the second magnetic component.

[0040] See also Figure 3 The first test sensor 21 is provided with an emitting end 211 for emitting a light source, that is, the first test sensor 21 is used as an emitting sensor, and an emitting hole 31, that is, a through hole, is provided on the first fixing frame 30 and is located above the emitting end 211, so that the size of the emitted light spot can be changed.

[0041] See also Figure 2 and Figure 3 The second test sensor 51 has the same structure as the first test sensor 21, and is provided with a receiving end (not marked in the figure) for receiving the light source, that is, the second test sensor 51 is used as a receiving sensor, and is matched with a receiving hole 61 provided on the second fixing frame 60, and the receiving hole 61 is located above the receiving end. When the light emitted by the transmitting end 211 is irradiated on the receiving end through the receiving hole 61, the first test sensor 21 and the second test sensor 51 are received in alignment, that is, the pairing is successful. In practical applications, this structure can be applied to equipment with strict requirements on the size of the light spot to ensure the alignment of the transmitting and receiving sensors.

[0042] See also Figure 3 and Figure 4The first positioning column 70 is correspondingly provided on the first product part 20 and the second product part 50.

[0043] See also Figure 3 A first magnetic component 100, i.e., a small magnet, is provided on the side of the first product part 20 and the second product part 50. One end of the first fixing frame 30 and the second fixing frame 60 are magnetically fixed to the first product part 20 and the second product part 50 respectively through the first magnetic component 100, so as to respectively abut the first test sensor 21 and the second test sensor 51, thereby facilitating the installation and removal of the first test sensor 21 and the second test sensor 51.

[0044] See also Figure 1 In this embodiment, the test fixture also includes a moving member 120, which can be a slide rail style. The first baffle 10 is set at one end of the moving member 120, and the second baffle 40 can be slidably engaged on the moving member 120, so that the distance between the second baffle 40 and the first baffle 10 can be flexibly adjusted to meet the pairing test of different distances.

[0047] See also Figure 2 and Figure 4 , the second positioning posts 80 are both arranged on the sides of the first product part 20 and the second product part 50. In another embodiment, when the transmitting end 211 of the first test sensor 21 and the receiving end of the second test sensor 51 are arranged on the sides, the first test sensor 21 and the second test sensor 51 can be respectively hung on the first product part 20 and the second product part 50 via the second positioning posts 80 to facilitate the assembly of the first test sensor 21 and the second test sensor 51. In this way, it can be selected whether the first test sensor 21 and the second test sensor 51 are installed on the first positioning posts 70 or the second positioning posts 80 based on the positions of the transmitting end 211 and the receiving end of the sensor.

[0048] The second positioning posts 80 are provided in pairs, and the side surfaces of the first product part 20 and the second product part 50 are both provided with second magnetic attraction members 110 (see Figure 3 ), located between the two second positioning posts 80, when the first test sensor 21 and the second test sensor 51 are installed on the second positioning posts 80, the second magnetic attraction member 110 is used to magnetically fix the first fixing frame 30 and the second fixing frame 60. In this embodiment, the first fixing frame 30 and the second fixing frame 60 also abut against the first test sensor 21 and the second test sensor 51 respectively, the emitting hole 31 of the first fixing frame 30 corresponds to the emitting end 211 of the first test sensor 21, and the receiving hole 61 of the second fixing frame 60 corresponds to the receiving end of the second test sensor 51.

[0049] See also Figure 4 and Figure 5 The first product part 20 and the second product part 50 are both provided with third positioning posts 90.

[0050] In summary, an optoelectronic sensor pairing test fixture disclosed in an embodiment of the present application can control the size of the light spot emitted by the transmitting end 211 by setting an emitting hole 31 on the first fixing frame 30, corresponding to the transmitting end 211 of the first test sensor 21; by setting a receiving hole 61 on the second fixing frame 60, corresponding to the receiving end of the first test sensor 21, the size of the light spot emitted by the transmitting end 211 can be received by aligning the core, and the resulting paired sensor can be suitable for equipment with strict requirements on the light spot size to ensure the alignment of the transmitting and receiving sensors; by setting the first positioning hole, the second positioning hole and the third positioning hole, different positioning columns can be selected for fixation based on different sensor styles, thereby increasing the applicability of the test fixture; the setting of the first magnetic suction member 100 and the second magnetic suction member 110 can facilitate the magnetic fixation of the first fixing frame 30 and the second fixing frame 60 at different positions, so as to facilitate the fixation and disassembly of the first fixing frame 30 and the second fixing frame 60.
