DETAILED DESCRIPTION

[0038] The embodiments of the technical solutions of the present application will be described in detail below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present application, and therefore only serve as examples, and cannot limit the protection scope of the present application.

[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the present application.

[0040] In the description of the embodiments of the present application, the technical terms "first", "second", etc. are only used to distinguish different objects, and cannot be understood as indicating or implying relative importance or implicitly indicating the number, specific order or primary and secondary relationship of the indicated technical features. In the description of the embodiments of the present application, the meaning of "multiple" is two or more, unless otherwise explicitly specified.

[0041] Please refer to Figure 1 , Figure 1 A structural schematic diagram of a light emission detection device 01 provided by an embodiment of the present application is shown in the figure. The light emission detection device 01 is used to realize light emission detection of a to-be-detected laser head in cooperation with a light emission element, and includes a connecting piece 10 provided with a light channel 101 and a light blocking piece 20 provided with a light emission port 201.

[0042] One end of the connecting piece 10 is fixedly connected to the light blocking piece 20.

[0043] The connecting piece 10 is provided with a first fastener 30 on the periphery; the connecting piece 10 is configured to cooperate with a second fastener on the inner side of the to-be-detected laser head based on the first fastener 30, so as to realize fixed connection between the connecting piece 10 and the to-be-detected laser head.

[0044] The light emission element is configured to be arranged in the light channel 101, and the light path of the light emission element passes through the center of the light channel 101 and the center of the light emission port 201.

[0045] The material of the connecting piece 10 can include alloy or stainless steel, etc. The axial section of the light channel 101 can be circular, polygonal or other reasonable shape. The color of the light blocking piece 20 can be black. The shape of the light outlet 201 can be circular, and the specific size of the light outlet 201 can be adjusted according to the specific implementation of the light emitting element and other actual conditions. The first fastener 30 can be a threaded structure, a clamp structure or a latch structure. The specific implementation of the first fastener 30 can be adjusted according to the specific model of the laser head to be tested. Exemplarily, in the case that the second fastener inside the laser head to be tested is realized by a clamp structure, the first fastener 30 can be realized by a clamp structure capable of realizing fixed connection with the second fastener. The light emitting element can be arranged in the middle region of the light channel 101 or in the region close to the light blocking piece 20 in the light channel 101. Since the light path of the light emitting element passes through the center of the light channel 101 and the center of the light outlet 201, in the case that the light emission of the laser head to be tested is normal, the light path of the light emitting element will pass through the center of the light channel 101, the center of the light outlet 201 and the nozzle center of the laser head to be tested; in the case that the light emission of the laser head to be tested is abnormal, the light path of the light emitting element will change, for example, offset or shielding, etc. Therefore, based on the light emission detection device 01, the light emission of the laser head to be tested can be detected by cooperating with the light emitting element.

[0046] Therefore, the light emission detection device 01 provided by the embodiment of the present application can fix the laser head to be tested on the periphery of the connecting piece 10 by the first fastener 30 and the second fastener, that is, place the connecting piece 10 (part) in the laser channel of the laser head to be tested; since the light path of the light emitting element passes through the center of the light channel 101 and the center of the light outlet 201, the light emitting element arranged in the light channel 101 can be controlled to emit light, so as to realize the light emission detection of the laser head to be tested based on the light emitted by the light emitting element, thereby reducing the cost of laser head detection. The technical problem of high cost of existing laser head detection is solved. In addition, based on the light emission detection device 01 improved by the embodiment of the present application, the laser head to be tested can be fixed on the periphery of the connecting piece 10 by the first fastener 30 and the second fastener, and the light emission detection of the laser head to be tested can be conveniently realized by observing the light emission of the laser head to be tested. The operation complexity of the laser head light emission detection is reduced.

[0047] In some optional embodiments, one end of the connecting piece 10 is provided with a third fastener; the end of the light blocking piece 20 close to the connecting piece 10 is provided with a fourth fastener; the connecting piece 10 is configured to realize the fixed connection between one end of the connecting piece 10 and the light blocking piece 20 based on the cooperation of the third fastener and the fourth fastener.

[0048] The third or fourth fastener can be a threaded structure, a clamp-type structure, or a pin structure. For example, if the third fastener is a threaded structure, the fourth fastener can be a threaded structure that cooperates with the third fastener to achieve a fixed connection. The specific implementation of the third and fourth fasteners can be adjusted according to the actual application, and this application does not impose specific limitations on this. Since one end of the connector 10 and the end of the light-blocking member 20 near the connector 10 are respectively provided with a third fastener and a fourth fastener, a fixed connection between one end of the connector 10 and the light-blocking member 20 can be achieved based on the third fastener cooperating with the fourth fastener. This reduces the difficulty of the connection operation between the connector 10 and the light-blocking member 20.

[0049] Please refer to Figure 2 , Figure 2 This is a schematic diagram of another light emission detection device 01 provided in an embodiment of this application.

[0050] In some optional embodiments, the light emission detection device 01 further includes: an end cap 40; the other end of the connector 10 is fixedly connected to the end cap 40; the other end of the connector 10 is provided with a fifth fastener, and the end cap 40 near the connector 10 is provided with a sixth fastener; the connector 10 is configured to achieve a fixed connection between the other end of the connector 10 and the end cap 40 based on the fifth fastener and the sixth fastener.

[0051] Specifically, the end cap 40 can be disposed at one end of the connector 10 away from the light-emitting element (e.g., Figure 2 (As shown). The fifth or sixth fastener can be a threaded structure, a clamp structure, or a pin structure. For example, if the fifth fastener is implemented using a pin structure, the sixth fastener can be implemented using a pin structure that cooperates with the fifth fastener to achieve a fixed connection. The specific implementation of the fifth and sixth fasteners can be adjusted according to the actual application, and this application does not impose specific limitations on this. Since the other end of the connector 10 and the end of the end cap 40 near the connector 10 are respectively provided with the fifth and sixth fasteners, a fixed connection between the other end of the connector 10 and the end of the end cap 40 near the connector 10 can be achieved based on the fifth fastener cooperating with the sixth fastener. This reduces the difficulty of the connection operation between the connector 10 and the end cap 40. Furthermore, in the case where "the connector 10 is fixedly connected to the light-blocking member 20 by the third fastener and the fourth fastener; and the connector 10 is configured to be fixedly connected to the end cap 40 by the fifth fastener and the sixth fastener", the difficulty of disassembling the connector 10 and the light-blocking member 20 and the connector 10 and the end cap 40 can be reduced, and it is easier to clean the light-emitting element inside the light channel 101 of the connector 10.

[0052] In some optional embodiments, the light emission detection device 01 further comprises a sealing member 50; the sealing member 50 is arranged at the connecting position of the connecting member 10 and the laser head to be detected.

[0053] The material of the sealing member 50 can include rubber or polytetrafluoroethylene, etc. The sealing member 50 can be annular, specifically circular. The shape and size parameters of the sealing member 50 can be adjusted according to the shape and size data of the connecting position of the connecting member 10 and the laser head to be detected. The sealing degree of the connecting position between the connecting member 10 and the laser head to be detected can be improved by the sealing member 50. The possibility that the external dust enters the light channel through the connecting position between the connecting member 10 and the laser head to be detected, thereby affecting the detection performance of the light emission detection device 01, is reduced.

[0055] The specific size and shape of the positioning channel can be adjusted according to the specific implementation form of the light emission element. By arranging the positioning member 60 at the target installation position in the connecting member 10, the light emission element can be more quickly and accurately installed at the corresponding installation position in the light channel based on the positioning channel provided by the positioning member 60, so as to ensure that the light path of the light emission element passes through the center of the positioning channel, and improve the reliability of the light emission detection of the laser head to be detected based on the light emission detection device 01.

[0056] In some optional embodiments, the shape of the light emission port 201 includes a circle.

[0057] The shape of the light emission port 201 is set to a circle, and there is no gap, so as to improve the light emission quality of the light emission detection device 01, and obtain better light emission detection effect.

The embodiment of the present application further provides a laser head detection device 02, which comprises a light emission element 021 and the light emission detection device 01 as described in any one of the first aspect.

[0063] The light emitting element 021 can further include a cable and a power supply, and the driving element 0211 can be electrically connected through the cable and the power supply, and the driving element 0211 is powered by the power supply.

[0065] The diameter of the light outlet is adjusted according to the divergence angle of the laser diode, so that the light blocking piece can avoid blocking the laser emitted by the laser diode, and better light detection effect can be obtained. The positive and negative pins of the laser diode are welded with the positive and negative pins of the driving piece 0211, and the driving piece 0211 is welded with the cable connected with the power supply, so as to drive the laser diode to emit laser through the driving piece 0211, and cooperate with the light detection device 01 to realize light detection of the laser head to be detected.
