[0020] 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.

[0021] See also Figure 1-10 The present invention provides an automated laser aging test cabinet with rapid loading and unloading, comprising: a conveyor line 100 for conveying incoming lasers, at least three of which are arranged at intervals along a first direction (i.e., the F1 direction shown in the figure), and shift rods 101 are arranged at intervals on the conveyor line 100. Specifically, the shift rods 101 are fixed on the conveyor line 100; the drawings of the present invention show an embodiment of setting three conveyor lines 100 along the first direction, which can be increased or decreased according to actual usage requirements.

[0022] The incoming laser can be transported through a separately provided transport device or can be placed manually.

[0023] The test assembly 200 is arranged in parallel with the conveyor line 100. The test assembly 200 includes a base 201 that moves cyclically along a circulation line K. Specifically, the circulation line K is used to provide a movement path parallel to the conveyor line 100 and a path for the test assembly 200 to return to the initial waiting position. The circulation line K can be a waist-shaped guide rail; A test piece 202 is provided on the base 201. The test piece 202 may be a spring pin. Wires extending from the spring pin are connected to the positive and negative electrodes of a test power supply. A test current is applied, and the corresponding parameters to be tested are read out. The test data is fed back externally via wireless transmission technology. The test piece 202 is connected to a movable part 203. The conveyor line 100 drives the test assembly 200 to move synchronously via the lever 101, and the movable part 203 drives the test piece 202 to contact the laser. Multiple test pieces 202 may be provided for each conveyor line 100. A sensor is provided on the test piece 202 for real-time detection of whether the test piece 202 is in a test state. The feeding assembly 300 is provided at the feeding end of the conveyor line 100 and is used to continuously divert incoming lasers to the spaced conveyor lines 100; Unloading assembly 400, located at the discharge end of conveyor line 100, is used to transport tested lasers outward. Specifically, unloading assembly 400, similar to loading assembly 300, is used to divert incoming lasers to different levels of conveyor lines 100. Unloading assembly 400 is used to bring tested lasers from different levels of conveyor lines 100 back to the unloading position (the unloading position is located at the discharge end of the lowest conveyor line 100).

[0024] In this embodiment, the incoming laser is placed on the loading assembly 300. The loading assembly 300 efficiently diverts the laser to different layers of the conveyor line 100 according to the occupancy status of the test piece 202 on the conveyor line 100 fed back from different layers, so that the incoming laser can be quickly matched with the test piece 202. When the laser is conveyed to the conveyor line 100, the lever 101 synchronously drives the waiting base 201 to move, and causes the movable part 203 to drive the test piece 202 to dock with the laser. After docking, they continue to maintain contact and move synchronously along the direction of the conveyor line 100 to complete the testing operation. Subsequently, the lasers of different layers are conveyed to the same height position as the feed through the unloading assembly 400 for unloading. The present invention adopts a continuous flow loading and unloading method and performs testing operations synchronously during the conveying process, which reduces the waiting time during the testing process, makes full use of time redundancy, and greatly improves the testing efficiency. The layered loading and unloading method not only reduces the equipment occupation area, but also can meet the testing needs of more lasers in a limited space, meeting the needs of large-scale testing.

[0025] In this embodiment, a guide platform 500 is provided between the test assembly 200 and the conveyor line 100. The guide platform 500 has a first guide surface 501 that contacts the movable part 203. The first guide surface 501 has a two-stage stepped surface structure, and the transition position of the stepped surface is an arc surface. The movable part 203 slides along the first guide surface 501 to make the test piece 202 contact or separate from the laser.

[0026] Specifically, the movable member 203 may adopt a shaft-shaped structure or a spherical structure, and the movable member 203 and the guide platform 500 may have rolling friction or sliding friction.

[0027] This embodiment is configured such that after the laser is transferred to the conveyor line 100, as the conveyor line 100 operates, the lever 101 takes away a waiting base 201 and moves synchronously. At this time, the movable part 203 follows the base 201 to move on the first guide surface 501 on the guide platform 500. During the transition process of the step surface on the first guide surface 501, the movable part 203 will synchronously drive the test piece 202 to gradually approach the laser until it is connected to the laser. Then the movable part 203 continues to move along the step surface after the transition. During the process, the test piece 202 continues to maintain contact with the laser until the test operation is completed, and is reset along the circulation line K with the base 201, so that the test piece 202 is separated from the laser to facilitate subsequent unloading.

[0028] In this embodiment, a positioning plate 102 is provided on the conveyor line 100, and the end of the positioning plate 102 has an arc surface, which is movably abutted against one end of a pushing member 103 provided on the conveyor line 100. Specifically, the pushing member 103 is movably connected to the conveyor line 100, and the other end of the pushing member 103 intermittently contacts the second guide surface 502 provided on the guide platform 500. The pushing member 103 slides on the second guide surface 502 to move the positioning plate 102, and cooperates with the lever 101 to clamp and fix the laser.

[0029] Specifically, the pushing member 103 may adopt a shaft-shaped structure or a spherical structure, and the pushing member 103 and the guide platform 500 may have rolling friction or sliding friction.

[0030] The conveyor line 100 is provided with a spring connected to the positioning plate 102 , for assisting the pushing member 103 in resetting after it is separated from the second guide surface 502 .

[0031] This embodiment is configured such that after the laser is conveyed to the conveyor line 100, the pusher 103 moves along the second guide surface 502 on the guide platform 500. During the transition of the pusher 103 to the stepped surface on the second guide surface 502, the pusher 103 moves toward the positioning plate 102, and will synchronously push the positioning plate 102 to move along the surface of the conveyor line 100 toward the lever 101. The position of the laser is fixed by the positioning plate 102 and the lever 101 to ensure the stability of the laser during subsequent testing.

[0032] Preferably, in this embodiment, the positioning plate 102 is provided with a guiding inclined plate for guiding the laser to the area between the positioning plate 102 and the shifting rod 101 .

[0033] In this embodiment, the transition position of the first guide surface 501 (the transition position refers to the connection between the stepped surfaces on the first guide surface 501) is located behind the transition position of the second guide surface 502 (the transition position refers to the connection between the stepped surfaces on the second guide surface 502).

[0034] This embodiment is configured such that the pushing member 103 moves before the movable member 203, ensuring that the laser is first fixed in position, and then the test member 202 is docked with the laser to ensure the stability of the connection.

[0035] In this embodiment, the test component 200 also includes a sleeve 204, one end of the sleeve 204 is connected to the base 201 through an elastic member 205, and the other end is movably abutted against the slide 206, and the slide 206 is provided with a stepped surface, and the stepped surface has a strip groove 207, and the strip groove 207 is provided with a power-carrying guide rail 208, wherein a contact head 209 is provided in the sleeve 204, and the contact head 209 extends out and contacts the power-carrying guide rail 208 when the sleeve 204 slides along the slide 206.

[0036] The contact timing between the sliding sleeve 204 and the sliding table 206 is before the pushing member 103 contacts the second guide surface 502 , between the pushing member 103 and the movable member 203 and the guide table 500 , or after the movable member 203 contacts the first guide surface 501 .

[0037] This embodiment is configured such that when the lever 101 drives the waiting test piece 202 to move, the sleeve 204 moves synchronously on the slide 206. When the sleeve 204 transitions to the stepped surface on the slide 206, the elastic member 205 is in a gradually compressed state. At this time, the contact head 209 located in the sleeve 204 will extend and contact the powered guide rail 208 provided in the strip groove 207, so that the entire test assembly 200 is in a power supply state, so that subsequent test operations can be carried out smoothly. Through intermittent power supply measures, multiple test pieces 202 can move in a cycle along the circulation line K without interfering with each other, thereby improving the testing capability and efficiency of the test assembly 200 supporting a single conveyor line 100.

[0038] In this embodiment, the loading assembly 300 includes a supporting plate 301 that moves linearly back and forth (the direction of the linear reciprocating movement is parallel to the conveying direction of the conveyor line 100) and a "mouth" shaped (i.e. Figure 9 The lifting plate 302 reciprocates in the direction of movement shown in the figure), and the supporting plate 301 and the lifting plate 302 alternately support the laser and lift the laser to the feeding end of the conveying line 100 spaced apart along the first direction.

[0039] Specifically, the support plate 301 is arranged on a transverse guide rail and is driven to move back and forth by a linear motor or a linear cylinder. The lifting plate 302 is arranged on another transverse guide rail, and the transverse guide rail slides with the vertical guide rail, and both are driven to move back and forth in a "mouth" shaped path by a linear motor or a linear cylinder.

[0040] This embodiment is configured such that the laser is first placed on the bottom support plate 301. When there is a waiting test piece 202 on the conveyor line 100 on the same layer, the laser is directly pushed to the conveyor line 100 on that layer. When the test pieces 202 on the conveyor line 100 on that layer are all in working condition, the laser is lifted up one layer by the lifting plate 302, and then the use status of the test piece 202 on the conveyor line 100 on that layer is judged. If there is still no waiting test piece 202 available for use, the lifting plate 302 at the previous position alternately lifts the laser again to the upper conveyor line 100. In this way, the laser can be quickly diverted to conveyor lines 100 on different layers. Through the layered loading and unloading method, not only the equipment occupation area is reduced, but also the testing needs of more lasers can be met in a limited space, meeting the needs of large-scale testing.

[0041] In this embodiment, the support plate 301 has a supporting surface that can accommodate at least two lasers, and the support plate 301 has a first material transfer mechanism 303 for transferring the laser to the conveyor line 100 and a second material transfer mechanism 304 for transferring the laser to the loading position (when the support plate 301 carries multiple lasers, the position of the laser closest to the feed end of the conveyor line 100 is the loading position).

[0042] Specifically, the first material shifting mechanism 303 includes an electric slide rail, an electric slider is provided on the electric slide rail, and a material shifting plate is provided on the electric slider; the second material shifting mechanism 304 has the same structure as the first material shifting mechanism 303 .

[0043] In this embodiment, the support plate 301 has a support surface that can accommodate at least two lasers, which allows the lifting plate 302 to lift at least two lasers at a time, reducing the distance that the two lasers need to be continuously lifted to the third-level conveyor line 100, further improving the loading efficiency. Taking the single lifting of two lasers as an example, the lifting plate 302 first lifts the two lasers from the first layer to the second layer, the conveyor line 100 on the second layer takes away one of the lasers, and the other laser is transferred to the support plate 301 on the second layer by the second material transfer mechanism 304, and then lifted to the conveyor line 100 on the third layer by the lifting plate 302 on the upper layer, avoiding the lack of continuous laser supply on the conveyor line 100 on the third layer due to the conveyor line 100 on the first layer taking over the loaded laser, thereby improving the overall testing efficiency.

[0044] In one embodiment, there are N supporting plates 301 and N-1 lifting plates 302 , where N≥2.

[0045] In one embodiment, the supporting plate 301 has a notch for the lifting plate 302 to pass through, and both sides of the supporting plate 301 are provided with blocking bars.

[0046] This embodiment is configured such that, through the interpenetrating structure between the support plate 301 and the lifting plate 302, it is not only possible to better maintain the support balance of the laser during the process of alternating laser transmission between the two, but also to reduce the problem of excessive occupied area caused by structural accumulation.

[0047] In this embodiment, a reset block 600 is further included. A clamping member 601 is provided on the reset block 600, and the reset block 600 is arranged on a guide rail 602. The reset block 600 can move back and forth along the path of the circulation line K, and is used to reset the test piece 202 separated from the laser to the loading end of the conveyor line 100.

[0048] Specifically, the reset block 600 cooperates with the guide rail 602 through a slider, and the base 201 has a protruding portion connected to the clamping member 601 .

[0049] This embodiment is configured such that when the test piece 202 follows the conveyor line 100 and moves to the unloading position, the movable part 203 and the sliding sleeve 204 are respectively disengaged from the guide table 500 and the slide 206. At this time, the base 201 is connected through the clamping part 601, and the reset block 600 is driven to move along the guide rail 602 along the circulation line K, so that the test piece 202 is reset to the waiting position, ensuring the continuous use of the test piece 202 without interfering with the subsequent movement of the test piece 202, thereby ensuring the test efficiency.

[0050] 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.

[0051] 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.

[0052] The above are only 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 should be included in the scope of protection of the present invention.
