Description

Technical Field

[0001] The present invention relates to the technical field of lasers, and in particular to a laser-assisted detection device and a laser detection method. Background Art

[0002] With the increasingly wide use of lasers, the demand for lasers in all walks of life is also increasing. At the same time, more stringent requirements are put forward for the reliability of lasers, which makes manufacturers need to conduct a series of tests on lasers after they are manufactured, including the tests on the life and anti-aging degree of lasers. Since the detection of lasers requires a process and cannot be completed in a short time, the currently used detection devices generally have the problem that the single detection action is not efficient enough, and an efficient detection process operation cannot be formed, resulting in a large amount of redundant actions in the detection process, greatly reducing the detection efficiency and making it difficult to meet the detection requirements for a large number of lasers. Summary of the Invention

[0003] The main purpose of the present invention is to provide a laser-assisted 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, including: A central table, on the surface of which there are a first guide groove and a second guide groove that are communicated with each other. A detection member corresponding to the position of the second guide groove is provided on the central table. 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; An outer ring seat is provided around the central table and rotates around an axis. A plurality of bearing seats for placing lasers are provided on the outer ring seat. Guide rods that slide in the first guide groove and the second guide groove are provided on the bearing seats; 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.

[0005] Further, the second guide groove and the first guide groove are provided at different positions on the side surface of the central table and are kept parallel to each other. The first guide groove and the second guide groove are smoothly connected.

[0006] Further, the driving member includes a missing gear provided on the central table. The convex teeth on the missing gear extend into the second guide groove. Among them, the guide rod includes a first end and a second end. The end facing the central table is the first end, and the end facing the bearing seat is the second end. The first end of the guide rod has a tooth groove meshed with the convex teeth.

[0007] Further, the driving member further includes a guide table, on which there are a first surface and a second surface with different heights and smooth transitions. The end of the rotating arm is in movable contact with the guide table. During the process that the end of the rotating arm follows the movement of the missing gear and transitions from the first surface to the second surface, the detecting member is rotated to contact the laser on the bearing seat.

[0008] Further, the second end of the guide rod is rotatably connected to the bearing seat.

[0009] Further, it further includes a shifting rod arranged at the end of the first guide groove. The shifting rod moves intermittently and is used to guide the passing guide rod from the first guide groove into the second guide groove.

[0010] Further, it further 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 both sides. One side of the convex teeth is meshed and connected with the upper rack through a transmission gear, and the upper rack is fixedly connected with the missing gear. The other side of the convex teeth contacts the first end of the guide rod moving into the first guide groove.

[0011] Further, the first guide groove has a first guiding surface and a second guiding surface with different heights and smooth transitions. When the first end of the guide rod transitions from the first guiding surface to the second guiding surface, the first end of the guide rod is disengaged from the lower rack.

[0012] Further, the second guide groove includes a first section groove and a second section groove arranged in parallel, and both ends of the first section groove and the second section groove are smoothly transitionally connected to the first guide groove.

[0013] A laser detection method, using the laser-assisted detection device mentioned above, includes the following steps: Place the laser to be detected on the bearing seat. As the outer ring seat rotates, the laser is moved to the detection position. As the guide rod enters the second guide groove from the first guide groove, the missing gear is driven to rotate, and synchronously, the rotating arm drives the detecting member to move and contact the laser for detection. During the process that the guide rod moves in the second guide groove, the detecting member keeps in continuous contact with the laser until the guide rod re-enters the first guide groove from the second guide groove, and the detection operation of the laser is completed.

[0014] The beneficial effects of the present invention are embodied in: The present invention uses an outer ring base that rotates around a central platform to continuously drive a laser to be detected to a detection position at the central platform. After the laser enters the detection position, a detection member is automatically driven by a guide rod to contact the laser for detection, and the contact is maintained during the movement of the laser until the entire detection process is completed. As the outer ring base continues to rotate, the detection member is successively driven to contact the laser for detection, reducing the redundant actions during the laser detection process and improving the detection efficiency.

[0015] Through the cooperation of a lower rack and an upper rack, 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 deficient gear to reset, causing the detection member to reset, so as to handle the subsequent laser detection operations conveyed.

[0016] The present invention drives the guide rod to move on the central platform through the outer ring base, and automatically realizes the connection and disconnection of the detection member during the movement process, with simple and fast operation and high reliability.

Detailed implementation mode

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Without 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 those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0020] Please refer to Figure 1 , 2 , 3, 6, the present invention provides a laser-assisted detection device, including: a central table 100, on the surface of which there are a first guide groove 101 and a second guide groove 102 that communicate with each other. A detection piece 200 corresponding to the position of the second guide groove 102 is provided on the central table 100. Specifically, the detection piece is a spring needle, and the wires led out by the spring needle are connected to the positive and negative electrodes of a test power supply to apply a test current, and the parameters to be tested are read out correspondingly; the detection piece 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 piece 202; specifically, the rotating arm 201 is slidably connected to the central table 100 through a slide block 203.

[0021] An outer ring seat 300 is provided outside the central table 100 and rotates around the axis. Specifically, the outer ring seat 300 is driven by a stepping motor. A plurality of bearing seats 301 for placing lasers are provided on the outer ring seat 300. Specifically, it is preferably set with 2 bearing seats, which can not only ensure the efficient transmission of the laser, but also leave enough time for detection; guide rods 302 that slide in the first guide groove 101 and the second guide groove 102 are provided on the bearing seats 301; In this embodiment, the laser to be detected is placed on the carrier seat 301, and the outer ring seat 300 is driven to rotate around the central table 100. During the process, the guide rod 302 moves synchronously in the first guide groove 101. When the guide rod 302 continuously moves 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 swing arm 201 drives the detecting member 200 to rotate, so that the detecting member 200 contacts the laser on the carrier 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, separating the guide rod 302 from the driving member 202 to complete the detection operation. Under the continuous rotation of the outer ring seat 300, the laser moves to the blanking position, completing the entire detection process of the laser.

[0022] In this embodiment, the outer ring seat 300 that rotates around the central table 100 continuously drives the laser to be detected to move to the detection position at the central table 100. After the laser enters the detection position, the guide rod 302 drives the detecting member 200 to automatically contact the laser for detection, and keeps in contact during the movement of the laser until the entire detection process is completed. With the continuous rotation of the outer ring seat 300, the detecting member 200 is successively driven to contact the laser for detection, reducing the action redundancy during the laser detection process and improving the detection efficiency.

[0023] In one embodiment, please refer to Figure 3 , the second guide groove 102 and the first guide groove 101 are arranged at different positions on the side of the central table 100 and are kept parallel to each other, and the first guide groove 101 and the second guide groove 102 are smoothly transitionally connected; specifically, the smooth transitional connection means that the connecting corner of the first guide groove 101 and the second guide groove 102 is rounded to ensure that the guide rod 302 can smoothly transition from the first guide groove 101 to the second guide groove 102.

[0024] With such a setting in this embodiment, the first guide groove 101 and the second guide groove 102 being located at different positions can directly accommodate subsequent functional expansions.

[0025] In one embodiment, please refer to Figure 3-5 , the driving member 202 includes a missing gear 2021 arranged on the central table 100, and the convex teeth on the missing gear 2021 extend into the second guide groove 102. Among them, the guide rod 302 includes a first end and a second end. The end facing the central table 100 is the first end, and the end facing the carrier seat 301 is the second end. The first end of the guide rod 302 has a tooth groove meshingly connected with the convex teeth. Specifically, the size of the tooth groove is larger than the size of the convex teeth.

[0026] In this embodiment, when the guide rod 302 follows the carrier 301 and moves 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, so that the detection member 200 follows the movement, ensuring that the detection operation continues during the movement of the laser.

[0027] In one embodiment, please refer to Figure 6 , the driving member 202 further includes a guide table 2022. The guide table 2022 has a first surface 2022a and a second surface 2022b with different heights and smooth transitions. The end of the rotating arm 201 is in movable contact with the guide table 2022; During the process that the end of the rotating arm 201 moves from the first surface 2022a to the second surface 2022b following the movement of the missing gear 2021, the detection member 200 is rotated to contact the laser on the carrier 301.

[0028] In this embodiment, it is arranged as follows. In the initial state, the detection member 200 is in an inclined state. When the guide rod 302 enters from the first guide groove 101 into the second guide groove 102, 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. The detection member 200 is driven by the rotating arm 201 to rotate, and then the detection member 200 contacts the laser.

[0029] In one embodiment, please refer to Figure 8 , the second end of the guide rod 302 is rotatably connected to the carrier 301.

[0030] In this embodiment, it is arranged as follows. 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 carrier 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.

[0031] In one embodiment, please refer to Figure 3 , it further includes a shift lever 103 arranged at the end of the first guide groove 101. The shift lever 103 moves intermittently and is used to guide the passing guide rod 302 from the first guide groove 101 to the second guide groove 102.

[0032] In this embodiment, it is arranged as follows. When the guide rod 302 transitions from the first guide groove 101 to the second guide groove 102, the shift lever 103 first pushes the guide rod 302 upward, so that the guide rod 302 can enter the second guide groove 102 more smoothly, avoiding the problem of jamming caused by poor cooperation between the guide rod 302 and the guide groove, and improving the smoothness of the detection.

[0033] Specifically, the lever 103 can be driven by a cylinder.

[0034] Preferably, a sensor is provided at the lever 103 for detecting the passing guide rod 302 and controlling the lever 103 to push the guide rod 302 to rotate.

[0035] In one embodiment, please refer to Figure 3 and Figure 4 , it further 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 section on the deficient 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 a transmission gear 105, and the upper rack 106 is fixedly connected with the deficient 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.

[0036] With such a setting in this embodiment, when the laser completes the detection operation, the guide rod 302 transitions from the second guide groove 102 to the first guide groove 101, 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. Through the transmission gear 105, it synchronously pushes the upper rack 106 to move in the reverse direction, thereby pushing the deficient gear 2021 to reset, and finally enabling the detection piece 200 to reset, continuously and without interruption to meet the subsequent laser detection requirements.

[0037] In one embodiment, please refer to Figure 7 , the first guide groove 101 has a first guiding surface 101a and a second guiding surface 101b with different heights and smooth transitions. When the first end of the guide rod 302 transitions from the first guiding surface 101a to the second guiding surface 101b, the first end of the guide rod 302 is disengaged from the lower rack 104.

[0038] Specifically, the length of the first guiding surface 101a is the same as the length of the lower rack 104.

[0039] With such a setting in this embodiment, when the guide rod 302 pushes the lower rack 104 to move, the guide rod 302 moves along the first guiding surface 101a. When the guide rod 302 transitions from the first guiding surface 101a to the second guiding surface 101b, its first end is disengaged from the lower rack 104. At this time, the upper rack 106 has driven the deficient gear 2021 to reset, enabling the detection piece 200 to reset. Subsequently, the guide rod 302 maintains this state until it enters the second guide groove 102 again.

[0040] It should be noted that the convex teeth on the first convex tooth surface of the lower rack 104 extend to the first guiding surface 101a, and an opening for the movement of the convex teeth is formed on the first guiding surface 101a.

[0041] Specifically, the guide rod 302 is composed of two mutually sleeved support rods, and the support rods are connected by elastic members.

[0042] In one embodiment, please refer to Figure 9 , the second guide groove 102 includes a first section groove 1021 and a second section groove 1022 arranged in parallel, and both ends of the first section groove 1021 and the second section groove 1022 are smoothly and transitionally connected to the first guide groove 101.

[0043] In this embodiment, since the detection member 200 moves synchronously with the laser during the detection of the laser, when the previous laser completes the detection operation, the detection member 200 needs to be reset. In order to enable the subsequent laser to enter the detection process without waiting, in this embodiment, by driving the guide rod 302 to alternately enter the two section grooves of the second guide groove 102, when the detection corresponding to one of the section grooves is carried out following the movement of the previous laser, the detection operation of the subsequent laser can be quickly connected, reducing the reset waiting time of the detection member 200, improving the fluency of the detection, and further improving the detection efficiency.

[0044] Specifically, when the carrier seat 301 carrying the previous laser moves along with the outer ring seat 300, the corresponding guide rod 302 first enters the first section groove 1021 from the first guide groove 101 and completes the subsequent detection operation. The guide rod 302 corresponding to the carrier seat 301 carrying the subsequent laser enters the second section groove 1022 from the first guide groove 101 and completes the subsequent detection operation, improving the detection connection effect of adjacent lasers and further improving the detection efficiency.

[0045] It should be noted that in this embodiment, two sets of corresponding detection members 200 and the structures for driving the detection members 200 to move and reset are symmetrically arranged on the central platform 100. Figure 9 Only the schematic diagram of the second guide groove 102 is shown; at the same time, in this embodiment, the carrier seat 301 adopts a structure in which the lasers are placed in sequence on the top surface and the bottom surface to facilitate the detection operation of the detection member 200 located below.

[0046] In one embodiment, a fixing structure for fixing the laser is provided in the carrier seat 301.

[0047] Specifically, the fixing structure can adopt a magnetic attraction structure or other structures that can achieve a fixing effect.

[0048] The present invention also provides a laser detection method, which uses the laser auxiliary detection device as described above, and includes the following steps: Place the laser to be detected on the carrier 301. As the outer ring base 300 rotates, the laser is moved to the detection position; As the guide rod 302 enters the second guide groove 102 from the first guide groove 101, the driving missing gear 2021 rotates, and synchronously the swing arm 201 drives the detection member 200 to move and contact the laser for detection; During the movement of the guide rod 302 in the second guide groove 102, the detection member 200 remains in 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.

[0049] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present invention, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0050] In addition, if there are descriptions such as "first" and "second" involved 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 implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the meaning of "and / or" appearing throughout the text includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, or solution B, or the solution where A and B are satisfied simultaneously. In addition, "a plurality" means two or more. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those skilled in the art can implement it. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist.

[0051] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
