DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. The embodiments in the present application and the features in the embodiments can be combined with each other without conflict. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0036] Please refer to Figures 1-10 The present application provides a kind of quick feeding and discharging of automatic laser aging test cabinet, comprising: conveying line 100, for conveying incoming laser, at least interval is provided with three along first direction (i.e. the F1 direction shown in figure), and its interval is provided with push rod 101, specifically, push rod 101 is fixed on conveying line 100;Three conveying lines 100 along the first direction are given in the drawings of the present application, and increase or decrease can be carried out according to actual use demand.

[0037] Incoming laser can be conveyed by additionally arranged conveying device, and can also be placed manually by artificial hand.

[0038] Test assembly 200 is arranged side by side with conveying line 100, and test assembly 200 includes base 201 moving along circulation line K, specifically, circulation line K is used to provide test assembly 200 with the moving path parallel to conveying line 100 and the path returning to initial waiting position, and circulation line K can be waist-shaped guide rail.

[0039] The base 201 is provided with a test piece 202, which can adopt a spring needle. The lead wire led out of the spring needle is connected to the positive and negative poles of a test power supply to apply a test current, and the corresponding read-out parameter to be tested is fed back to the outside through wireless transmission technology. The test piece 202 is connected with a movable piece 203, and the conveying line 100 drives the test assembly 200 to move synchronously through the lever 101, and the movable piece 203 drives the test piece 202 to contact with the laser. Each test piece 202 corresponding to each conveying line 100 can be provided with a plurality of test pieces 202. A sensor is arranged on the test piece 202 for real-time detection of whether the test piece 202 is in a test state.

[0040] The feeding assembly 300 is arranged at the feeding end of the conveying line 100, and is used for continuously distributing the incoming laser to the spaced conveying lines 100.

[0041] The discharging assembly 400 is arranged at the discharging end of the conveying line 100, and is used for conveying the tested laser to the outside. Specifically, the discharging assembly 400 is the same as the feeding assembly 300, and is used for distributing the incoming laser to different layers of conveying lines 100. The discharging assembly 400 is used for bringing the tested laser on the different layers of conveying lines 100 back to the discharging position (the discharging position is located at the position of the discharging end of the lowermost conveying line 100).

[0042] In the embodiment, the incoming laser is placed on the feeding assembly 300. The feeding assembly 300 distributes the laser to different layers of conveying lines 100 according to the occupied state of the test piece 202 on the conveying line 100 fed back by different layers, so that the incoming laser can be quickly matched with the test piece 202. When the laser is conveyed to the conveying line 100, the lever 101 synchronously drives the waiting base 201 to move, and the movable piece 203 drives the test piece 202 to be connected with the laser. After the connection, the test piece 202 continuously maintains the contact and moves synchronously along the conveying line 100, thereby completing the test work. Then, the discharging assembly 400 conveys the laser on different layers to the position with the same height as the feeding position for discharging. The present application uses the continuous feeding and discharging mode, and synchronously performs the test work during the conveying process, thereby reducing the waiting time in the test process, fully utilizing the time redundancy, and greatly improving the test efficiency. Through the layered feeding and discharging mode, the equipment occupation area is reduced, and more laser tests can be met in a limited space to meet the large batch test demand.

[0043] In the embodiment, a guide table 500 is arranged between the test assembly 200 and the conveying line 100. The guide table 500 has a first guide surface 501 in contact with the movable piece 203. The first guide surface 501 is a two-section stepped surface structure, and the transition position of the stepped surface is arc-shaped. The movable piece 203 slides along the first guide surface 501 to make the test piece 202 contact or separate from the laser.

[0044] Specifically, the movable part 203 can adopt a shaft structure or a spherical structure, and the movable part 203 and the guide table 500 can be in rolling friction or sliding friction.

[0045] In this embodiment, when the laser is conveyed onto the conveying line 100, the push rod 101 moves away from a waiting base 201 synchronously with the operation of the conveying line 100. At this time, the movable part 203 moves on the first guide surface 501 of the guide table 500 along with the base 201, and the movable part 203 drives the testing part 202 to gradually approach the laser during the transition of the stepped surface on the first guide surface 501, until the testing part 202 is connected with the laser. Then, the movable part 203 continuously moves along the stepped surface after the transition, and the testing part 202 continuously contacts with the laser during the process, until the testing operation is completed. Then, the base 201 is reset along the circulation line K, so that the testing part 202 is separated from the laser, facilitating the subsequent unloading.

[0046] In this embodiment, the conveying line 100 is provided with a positioning plate 102, and the end of the positioning plate 102 has a curved surface part which is movably abutted with one end of a pushing part 103 provided on the conveying line 100. Specifically, the pushing part 103 is movably connected with the conveying line 100, and the other end of the pushing part 103 is intermittently contacted with a second guide surface 502 provided on the guide table 500. The pushing part 103 slides on the second guide surface 502 to move the positioning plate 102, and cooperates with the push rod 101 to clamp and fix the laser.

[0047] Specifically, the pushing part 103 can adopt a shaft structure or a spherical structure, and the pushing part 103 and the guide table 500 can be in rolling friction or sliding friction.

[0048] In this embodiment, the conveying line 100 is provided with a spring connected with the positioning plate 102, for assisting the resetting of the pushing part 103 after the pushing part 103 is separated from the second guide surface 502.

[0049] In this embodiment, when the laser is conveyed onto the conveying line 100, the pushing part 103 moves along the second guide surface 502 of the guide table 500. During the transition of the stepped surface on the second guide surface 502, the pushing part 103 moves towards the positioning plate 102, and synchronously pushes the positioning plate 102 to move along the surface of the conveying line 100 towards the push rod 101. The positioning plate 102 and the push rod 101 fix the position of the laser, to ensure the stability of the laser in the subsequent testing process.

[0050] Preferably, the positioning plate 102 has a guide inclined plate in this embodiment, for guiding the laser into the area between the positioning plate 102 and the push rod 101.

[0051] In the embodiment, the transition position (transition position refers to the connection position of the stepped surface) of the first guide surface 501 is located at the rear side of the transition position (transition position refers to the connection position of the stepped surface) of the second guide surface 502.

[0052] In the embodiment, the pusher 103 is arranged to move before the movable member 203, so that the position fixing action of the laser is completed first, and then the test member 202 is connected to the laser, thereby ensuring the stability of the connection.

[0053] In the embodiment, the test assembly 200 further comprises a sliding sleeve 204, one end of the sliding sleeve 204 is connected to the base 201 through an elastic member 205, and the other end is movably connected to a sliding table 206, the sliding table 206 is provided with a stepped surface, the stepped surface is provided with a strip-shaped groove 207, and the strip-shaped groove 207 is provided with a power supply rail 208, wherein the sliding sleeve 204 is provided with a contact head 209, and the contact head 209 is extended to contact the power supply rail 208 during the sliding of the sliding sleeve 204 along the sliding table 206.

[0054] The contact timing of the sliding sleeve 204 and the sliding table 206 is before the contact between the pusher 103 and the second guide surface 502, or between the contact between the pusher 103 and the movable member 203 and the guide table 500, or after the contact between the movable member 203 and the first guide surface 501.

[0055] In the embodiment, when the test member 202 is moved by the lever 101, the sliding sleeve 204 moves synchronously on the sliding table 206, when the sliding sleeve 204 moves on the stepped surface of the sliding table 206, the elastic member 205 is gradually compressed, at this time, the contact head 209 in the sliding sleeve 204 is extended and contacts the power supply rail 208 in the strip-shaped groove 207, so that the whole test assembly 200 is in a power supply state, so that the subsequent test operation can be smoothly carried out, and through the intermittent power supply measure, a plurality of test members 202 can move along the circulation line K and do not interfere with each other, thereby improving the test capacity and efficiency of the test assembly 200 matched with a single conveying line 100.

[0056] In the embodiment, the feeding assembly 300 comprises a supporting plate 301 moving linearly and reciprocally (the linear reciprocating direction is parallel to the conveying direction of the conveying line 100) and a lifting plate 302 moving reciprocally in a "mouth" shape (i.e. the movement direction as shown in the figure). Figure 9 The supporting plate 301 and the lifting plate 302 alternately receive the laser, and the laser is lifted to the feeding end of the conveying line 100 arranged along the first direction.

[0057] Specifically, the supporting 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, and the lifting plate 302 is arranged on another transverse guide rail which is in sliding cooperation with a vertical guide rail, and both are driven to move back and forth in a "mouth" shape by linear motors or linear cylinders.

[0058] In this embodiment, the laser is first placed on the lowermost supporting plate 301, and when there is a waiting test piece 202 on the conveying line 100 at the same layer, the laser is directly pushed to the conveying line 100 at this layer, and when all the test pieces 202 on the conveying line 100 at this layer are in a working state, the laser is lifted to the next layer by the lifting plate 302, and then the use state of the test piece 202 on the conveying line 100 at this layer is judged, and if there is still no waiting test piece 202 for use, the laser is lifted to the upper conveying line 100 again by the lifting plate 302 at the previous position. In this way, the laser can be quickly distributed to different layers of the conveying line 100, and through the layered feeding and discharging mode, not only the equipment occupation area is reduced, but also more lasers can be tested in a limited space, and the large batch testing demand can be met.

[0059] In this embodiment, the supporting plate 301 has a supporting surface capable of accommodating at least two lasers, and the supporting plate 301 has a first material pushing mechanism 303 for pushing the laser to the conveying line 100 and a second material pushing mechanism 304 for pushing the laser to the feeding position (when the supporting plate 301 carries multiple lasers, the position of the laser closest to the feeding end of the conveying line 100 is the feeding position).

[0060] Specifically, the first material pushing mechanism 303 includes an electric sliding rail, an electric sliding block is arranged on the electric sliding rail, and a material pushing plate is arranged on the electric sliding block; the second material pushing mechanism 304 has the same structure as the first material pushing mechanism 303.

[0061] In this embodiment, the supporting plate 301 has a supporting surface capable of accommodating at least two lasers, which can enable the lifting plate 302 to lift at least two lasers at a time, reducing the distance of the two lasers being continuously lifted to the third layer of the conveying line 100, and further improving the feeding efficiency.

[0062] Taking the lifting of two lasers at a time as an example, the lifting plate 302 first lifts the two lasers from the first layer to the second layer, the conveying line 100 at the second layer takes away one of the lasers, and the other laser is pushed to the second layer of the supporting plate 301 by the second material pushing mechanism 304, and then the lifting plate 302 at the upper layer lifts it to the third layer of the conveying line 100, avoiding the situation that the third layer of the conveying line 100 lacks continuous supply of lasers due to the fact that the first layer of the conveying line 100 receives the fed lasers, thereby improving the overall testing efficiency.

[0063] In an embodiment, the supporting plate 301 is provided with N, and the lifting plate 302 is provided with N-1, wherein N≥2.

[0064] In an embodiment, the supporting plate 301 has a gap for the lifting plate 302 to pass through, and the supporting plate 301 is provided with a blocking strip on both sides.

[0065] In this embodiment, the mutual penetration structure between the supporting plate 301 and the lifting plate 302 can not only better maintain the balance of supporting the laser during the alternating transmission of the laser, but also reduce the problem of excessive area occupation caused by structural accumulation.

[0066] In this embodiment, the reset block 600 is further included, the reset block 600 is provided with a clamping piece 601, and the reset block 600 is arranged on the guide rail 602. The reset block 600 can move back and forth along the path of the circulation line K, and is used for resetting the test piece 202 separated from the laser to the feeding end of the conveying line 100.

[0067] Specifically, the reset block 600 cooperates with the guide rail 602 through a sliding block, and the base 201 has a protruding part connected with the clamping piece 601.

[0068] In this embodiment, when the test piece 202 moves to the discharging position along the conveying line 100, the movable piece 203 and the sliding sleeve 204 are separated from the guide table 500 and the sliding table 206, respectively. At this time, the base 201 is connected with the clamping piece 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, which ensures the continuous use of the test piece 202 and does not interfere with the movement of the subsequent test piece 202, and ensures the test efficiency.

[0069] It should be noted that if the embodiment of the present application involves directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement condition, etc. between the components in a certain posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0070] In addition, if the description of the present application involves "first", "second" and the like, the description of "first", "second" and the like is only for the purpose of description, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features.

In addition, the meaning of "and / or" appearing throughout the text includes three parallel schemes. For example, "A and / or B" includes A scheme, or B scheme, or A and B scheme. In addition, "multiple" refers to more than two. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the realization of the ordinary skilled in the art, when the combination of technical solutions appears contradictory or cannot be realized, it should be considered that the combination of technical solutions does not exist.

[0071] The above is only the preferred embodiment of the present application, and is not used to limit the present application, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
