Description

Technical Field

[0001] The present invention relates to the field of laser technology, and in particular to a laser auxiliary detection device and a laser detection method. Background Art

[0002] As the use of lasers becomes more and more widespread, the demand for lasers in various industries is also increasing. At the same time, more stringent requirements are placed on the reliability of lasers, requiring manufacturers to perform a series of tests on the lasers after they are manufactured, including tests on the laser life and anti-aging degree. Since laser testing requires a process and cannot be completed in a short time, the current detection devices generally have the problem of insufficient efficiency in single detection actions, failing to form an efficient detection process operation, resulting in a large amount of action redundancy in the detection process, greatly reducing the detection efficiency, and making it difficult to meet the detection needs of large quantities of lasers. Summary of the Invention

[0003] The main purpose of the present invention is to provide a laser auxiliary detection device and a laser detection method, aiming to solve the existing technical problems.

[0004] To achieve the above object, the present invention provides a laser-assisted detection device, comprising:

[0005] A central platform, a surface of which is provided with a first guide groove and a second guide groove that are interconnected, a detection member corresponding to the position of the second guide groove is provided on the central platform, the detection member is connected to one end of a rotating arm, and the other end of the rotating arm is connected to a driving member;

[0006] An outer ring seat is provided on the periphery of the central platform and rotates around the axis, the outer ring seat is provided with a plurality of supporting seats for placing lasers, and the supporting seats are provided with guide rods sliding in the first guide groove and the second guide groove;

[0007] The outer ring seat drives the guide rod to move from the first guide groove to the second guide groove, and the guide rod contacts the driving member, so that the rotating arm drives the detection member to rotate and contact the laser for detection.

[0008] Furthermore, the second guide groove and the first guide groove are arranged at different positions on the side of the center platform and remain parallel to each other, and the first guide groove and the second guide groove are smoothly transitioned and connected.

[0009] Furthermore, the driving member includes a missing gear provided on the central platform, and the convex teeth on the missing gear extend into the second guide groove, wherein the guide rod includes a first end and a second end, the end facing the central platform is the first end, and the end facing the supporting seat is the second end, and the first end of the guide rod has a tooth groove engaged with the convex teeth.

[0010] Furthermore, the driving member also includes a guide platform, which has a first surface and a second surface with different heights and a smooth transition, and the end of the rotating arm is movably abutted against the guide platform, wherein the end of the rotating arm follows the movement of the missing gear and transitions from the first surface to the second surface, causing the detection member to rotate and contact the laser on the support seat.

[0011] Furthermore, the second end of the guide rod is rotatably connected to the bearing seat.

[0012] Furthermore, it also includes a shift rod provided at the end of the first guide groove, and the shift rod moves intermittently to guide the passing guide rod from the first guide groove to the second guide groove.

[0013] Furthermore, it also includes a lower rack movably arranged in the first guide groove and the second guide groove and having the same length as the convex tooth section on the missing gear. The lower rack has convex teeth on two sides, one of which is meshed with the upper rack through a transmission gear, and the upper rack is fixedly connected to the missing gear, and the other convex tooth contacts the first end of the guide rod that moves into the first guide groove.

[0014] Furthermore, the first guide groove has a first guide surface and a second guide surface of different heights and a smooth transition, and when the first end of the guide rod transitions from the first guide surface to the second guide surface, the first end of the guide rod is disengaged from the lower rack.

[0015] Furthermore, the second guide groove includes a first groove section and a second groove section that are arranged in parallel, and both ends of the first groove section and the second groove section are smoothly transitionally connected to the first guide groove.

[0016] A laser detection method, using the laser-assisted detection device mentioned above, comprises the following steps:

[0017] Place the laser to be tested on the support base, and as the outer ring base rotates, the laser is moved to the testing position;

[0018] As the guide rod enters the second guide groove from the first guide groove, the missing gear is driven to rotate, and the rotating arm drives the detection part to move and contact with the laser for detection;

[0019] During the movement of the guide rod in the second guide groove, the detection member maintains continuous contact with the laser until the guide rod re-enters the first guide groove from the second guide groove, completing the detection operation of the laser.

[0020] The beneficial effects of the present invention are embodied in:

[0021] The present invention continuously drives the laser to be detected to the detection position on the central platform by rotating the outer ring seat around the central platform. After the laser enters the detection position, the guide rod drives the detection part to automatically contact the laser for detection, and maintains contact during the movement of the laser until the entire detection process is completed. As the outer ring seat continues to rotate, the detection part is driven to contact the laser for detection in turn, which reduces the action redundancy in the laser detection process and improves the detection efficiency.

[0022] The present invention cooperates with the lower rack and the upper rack so that when the guide rod enters the first guide groove from the second guide groove, it contacts the lower rack. As the guide rod moves, it pushes the missing gear to reset, so that the detection part is reset, thereby coping with the subsequent laser detection operation.

[0023] The present invention drives the guide rod to move on the middle platform through the outer ring seat, and automatically realizes the connection and separation of the detection part during the movement, which is simple and fast to operate and highly reliable.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0036] See also Figure 1 、 2 , 3, 6. The present invention provides a laser auxiliary detection device, including: a central platform 100, a surface of which is provided with a first guide groove 101 and a second guide groove 102 which are interconnected, a detection member 200 corresponding to the position of the second guide groove 102 is provided on the central platform 100, specifically, the detection member is a spring needle, the wires led out of the spring needle are connected to the positive and negative poles of the test power supply, a test current is applied, and the parameters to be tested are read accordingly; the detection member 200 is connected to one end of a rotating arm 201, and the other end of the rotating arm 201 is connected to a driving member 202; specifically, the rotating arm 201 is slidably connected to the central platform 100 through a slider 203.

[0037] The outer ring seat 300 is provided on the periphery of the central platform 100 and rotates around the axis. Specifically, the outer ring seat 300 is driven by a stepping motor and is provided with multiple supporting seats 301 for placing lasers. Specifically, two supporting seats are preferably provided to ensure efficient transmission of the lasers and to allow sufficient time for detection. The supporting seats 301 are provided with guide rods 302 that slide in the first guide groove 101 and the second guide groove 102.

[0038] In this embodiment, the laser to be tested is placed on the supporting seat 301, and the outer ring seat 300 is driven to rotate around the central platform 100. During the process, the guide rod 302 moves synchronously in the first guide groove 101. When the guide rod 302 continues to move and enters the second guide groove 102 from the first guide groove 101, the end of the guide rod 302 contacts the driving member 202, and the driving arm 201 drives the detection member 200 to rotate, so that the detection member 200 contacts the laser on the supporting seat 301 for detection operation. The detection process is carried out during the continuous rotation of the outer ring seat 300 until the guide rod 302 transitions from the second guide groove 102 to the first guide groove 101, so that the guide rod 302 is separated from the driving member 202, and the detection operation is completed. Under the continuous rotation of the outer ring seat 300, the laser moves to the unloading position, completing the entire detection process of the laser.

[0039] In this embodiment, the outer ring seat 300 rotates around the central table 100 to continuously drive the laser to be detected to the detection position on the central table 100, and after the laser enters the detection position, the guide rod 302 drives the detection member 200 to automatically contact the laser for detection, and maintains contact during the movement of the laser until the entire detection process is completed. As the outer ring seat 300 continues to rotate, the detection member 200 is driven in turn to contact the laser for detection, which reduces the action redundancy in the laser detection process and improves the detection efficiency.

[0040] In one embodiment, see Figure 3 The second guide groove 102 and the first guide groove 101 are arranged at different positions on the side of the center platform 100 and remain parallel to each other, and the first guide groove 101 and the second guide groove 102 are smoothly transitioned and connected; specifically, the smooth transition connection means that the corners where the first guide groove 101 and the second guide groove 102 are connected are rounded to ensure that the guide rod 302 can smoothly transition from the first guide groove 101 to the second guide groove 102.

[0041] In this embodiment, the first guide groove 101 and the second guide groove 102 are located at different positions, which can directly accommodate subsequent functional expansion.

[0042] In one embodiment, see Figure 3-5 The driving member 202 includes a missing gear 2021 mounted on the intermediate platform 100. The protruding teeth on the missing gear 2021 extend into the second guide slot 102. The guide rod 302 includes a first end and a second end. The first end faces the intermediate platform 100, while the second end faces the support base 301. The first end of the guide rod 302 has a tooth groove that meshes with the protruding teeth. Specifically, the tooth groove is larger than the protruding teeth.

[0043] This embodiment is configured such that when the guide rod 302 follows the supporting seat 301 to move from the first guide groove 101 to the second guide groove 102, the tooth groove at its first end contacts the convex teeth on the missing gear 2021. As the outer ring seat 300 continues to rotate, the guide rod 302 drives the missing gear 2021 to rotate synchronously, thereby causing the detection part 200 to follow the movement, ensuring that the detection operation is continuously performed during the movement of the laser.

[0044] In one embodiment, see Figure 6 The driving member 202 further includes a guide platform 2022 having a first surface 2022a and a second surface 2022b of different heights and a smooth transition, and the end of the rotating arm 201 is in movable contact with the guide platform 2022;

[0045] The end of the rotating arm 201 follows the movement of the missing gear 2021 and transitions from the first surface 2022 a to the second surface 2022 b , causing the detection member 200 to rotate and contact the laser on the supporting seat 301 .

[0046] This embodiment is configured such that, in the initial state, the detection member 200 is in an inclined state. When the guide rod 302 enters the second guide groove 102 from the first guide groove 101, the guide rod 302 drives the missing gear 2021 to rotate, and the rotating arm 201 rotates synchronously with the missing gear 2021, so that the end of the rotating arm 201 transitions from the first surface 2022a to the second surface 2022b, and the detection member 200 is driven to rotate through the rotating arm 201, thereby making the detection member 200 contact with the laser.

[0047] In one embodiment, see Figure 8 The second end of the guide rod 302 is rotatably connected to the bearing seat 301.

[0048] This embodiment is configured such that the guide rod 302 is always in the first guide groove 101 or the second guide groove 102. Through the rotational connection between the guide rod 302 and the supporting seat 301, the guide rod 302 can alternately enter the first section groove 1021 or the second section groove 1022, thereby improving the connection effect of the detection and achieving the purpose of improving the detection efficiency.

[0049] In one embodiment, see Figure 3 , and also includes a shift rod 103 provided at the end of the first guide groove 101. The shift rod 103 moves intermittently to guide the passing guide rod 302 from the first guide groove 101 to the second guide groove 102.

[0050] This embodiment is configured such that when the guide rod 302 transitions from the first guide groove 101 to the second guide groove 102, the guide rod 302 is first pushed upward by the shift rod 103, so that the guide rod 302 can enter the second guide groove 102 more smoothly, avoiding the problem of the guide rod 302 being stuck due to poor cooperation with the guide groove, thereby improving the smoothness of detection.

[0051] Specifically, the shifting rod 103 may be driven by a cylinder.

[0052] Preferably, a sensor is provided at the shifting rod 103 for detecting the passing guide rod 302 and controlling the shifting rod 103 to push the guide rod 302 to rotate.

[0053] In one embodiment, see Figure 3 and Figure 4 , and also includes a lower rack 104 movably arranged in the first guide groove 101 and the second guide groove 102 and having the same length as the convex tooth segment on the missing gear 2021. The lower rack 104 has convex teeth on both sides. Specifically, the plane parallel to the top surface of the middle platform 100 is the first convex tooth surface, and the plane perpendicular to the top surface of the middle platform 100 is the second convex tooth surface. The convex teeth on one side (i.e., the first convex tooth surface) are meshed and connected with the upper rack 106 through the transmission gear 105. The upper rack 106 is fixedly connected to the missing gear 2021. The convex teeth on the other side (i.e., the second convex tooth surface) are in contact with the first end of the guide rod 302 that moves into the first guide groove 101.

[0054] This embodiment is configured such that when the laser completes the detection operation, the guide rod 302 transitions from the second guide groove 102 to the first guide groove 101, and contacts the convex teeth on the second convex tooth surface of the lower rack 104, and as the outer ring seat 300 rotates, it pushes the lower rack 104 to move, and synchronously pushes the upper rack 106 to move in the opposite direction through the transmission gear 105, thereby pushing the missing gear 2021 to reset, and finally resetting the detection component 200, continuously and uninterruptedly connecting to subsequent laser detection needs.

[0055] In one embodiment, see Figure 7 The first guide groove 101 has a first guide surface 101a and a second guide surface 101b of different heights and a smooth transition. When the first end of the guide rod 302 transitions from the first guide surface 101a to the second guide surface 101b, the first end of the guide rod 302 is disengaged from the lower rack 104.

[0056] Specifically, the length of the first guide surface 101 a is the same as that of the lower rack 104 .

[0057] This embodiment is configured such that when the guide rod 302 pushes the lower rack 104 to move, the guide rod 302 moves along the first guide surface 101a. When the guide rod 302 transitions from the first guide surface 101a to the second guide surface 101b, its first end portion disengages from the lower rack 104. At this time, the upper rack 106 has driven the missing gear 2021 to reset, so that the detection member 200 is reset. Subsequently, the guide rod 302 maintains this state until it enters the second guide groove 102 again.

[0058] It should be noted that the convex teeth of the first convex tooth surface on the lower rack 104 extend into the first guide surface 101 a , and the first guide surface 101 a is provided with an opening for the convex teeth to move.

[0059] Specifically, the guide rod 302 is composed of two sections of support rods that are sleeved on each other, and the support rods are connected by elastic members.

[0060] In one embodiment, see Figure 9 The second guide groove 102 includes a first groove section 1021 and a second groove section 1022 arranged in parallel. Both ends of the first groove section 1021 and the second groove section 1022 are smoothly connected to the first guide groove 101.

[0061] This embodiment is configured in such a way that since the detection part 200 moves synchronously with the laser during the laser detection process, the detection part 200 needs to be reset after the previous laser completes the detection operation. In order to enable the next laser to enter the detection process without waiting, this embodiment drives the guide rod 302 to alternately enter the two sections of the second guide groove 102, so that when the detection corresponding to one section of the groove moves with the previous laser for detection, it can quickly connect the detection operation of the next laser, reducing the reset waiting time of the detection part 200, improving the fluency of the detection, and further improving the detection efficiency.

[0062] Specifically, when the supporting seat 301 carrying the previous laser moves with the outer ring seat 300, the correspondingly connected guide rod 302 first enters the first section groove 1021 from the first guide groove 101 and completes the subsequent detection operation. The correspondingly connected guide rod 302 of the supporting seat 301 carrying the next laser enters the second section groove 1022 from the first guide groove 101 and completes the subsequent detection operation, thereby improving the detection connection effect of adjacent lasers and further improving the detection efficiency.

[0063] It should be noted that, in this embodiment, the corresponding detection members 200 and the structure for driving the detection members 200 to move and reset are symmetrically provided in two groups on the central platform 100. Figure 9 Only a schematic diagram of the second guide groove 102 is shown; at the same time, in this embodiment, the support base 301 adopts a structure in which lasers are placed on the top and bottom surfaces in sequence to perform detection operations on the detection member 200 located below.

[0064] In one embodiment, a fixing structure for fixing the laser is provided in the supporting base 301 .

[0065] Specifically, the fixing structure may be a magnetic structure or other structure that can achieve a fixing effect.

[0066] The present invention also provides a laser detection method, using the laser-assisted detection device as described above, comprising the following steps:

[0067] Place the laser to be tested on the support base 301. As the outer ring base 300 rotates, the laser is moved to the testing position.

[0068] As the guide rod 302 enters the second guide groove 102 from the first guide groove 101, the gear 2021 is driven to rotate, and the rotating arm 201 drives the detection member 200 to move and contact the laser for detection;

[0069] During the movement of the guide rod 302 in the second guide groove 102 , the detection member 200 maintains continuous contact with the laser until the guide rod 302 re-enters the first guide groove 101 from the second guide groove 102 , completing the detection operation of the laser.

[0070] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), such directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0071] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the meaning of "and / or" appearing throughout the text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or schemes in which A and B are satisfied at the same time. In addition, "multiple" refers to more than two. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist.

[0072] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
