Technical Field
[0001] This utility model relates to the field of substrate packaging technology, and specifically to a sampling fixture for improving substrate damage during the sampling inspection process. Background Technology
[0002] Substrate sampling inspection is a crucial step in ensuring product quality in electronics manufacturing. Therefore, substrate sampling inspection fixtures are widely used in the electronics industry to ensure that substrate quality meets standard requirements and prevent defective products from entering the production line or market. However, current substrate sampling inspection fixtures have some problems in practical applications, affecting their effectiveness and stability.

The embodiments will be described below according to the overall structure of the utility model.
[0029] As Figs. 1 to 4 The utility model discloses a kind of for improving base loss in sampling process sampling fixture, for sampling and placing substrate in magazine 1, the magazine 1 has multiple placement grooves 11 on two inner side walls, corresponding placement groove 11 on the two inner side walls of the magazine 1 is located at the same height, the substrate is stored in the placement groove 11 one by one, and the sampling fixture includes:
[0030] Jig main body 2, the jig main body 2 includes bottom plate 21 and the first side plate 22 being located at the both sides of bottom plate 21 and being arranged along the length direction of bottom plate 21, the outer side of first side plate 22 is equipped with outer sliding groove 23;
[0031] Sliding cover mechanism, the sliding cover mechanism includes panel 31 with cavity and second side plate 32 located at the both sides of panel 31, the sliding cover mechanism is slidably connected with outer sliding groove 23 by second side plate 32, so that the sliding cover mechanism can move along the length direction of jig main body 2;
[0032] Clamping mechanism, the clamping mechanism includes two symmetrically arranged clamping parts 4, the clamping part 4 includes L-shaped control part 41 located in the cavity of panel 31, connecting plate 42 and pressing part 44 located below panel 31, and clamping jaw assembly connected below panel 31;
[0033] The connecting plate 42 is parallelly connected below the face plate 31, the middle position of the pressing part 44 is rotationally connected with the connecting plate 42, the pressing part 44 has a first end and a second end, the first end of the pressing part 44 is connected with the control part 41 through the first connecting rod 43, the first connecting rod 43 is rotationally connected with the control part 41 and the pressing part 44 respectively, the first end of the pressing part 44 is connected with the connecting plate 42 through the first spring 45; the clamp jaw assembly includes a lower clamp jaw 47 arranged below the face plate 31 through a second connecting rod 46 and an upper clamp jaw 48 connected below the face plate 31 through a second spring 49, the upper clamp jaw 48 is arranged outside the second connecting rod 46, and the second spring 49 is sleeved outside the second connecting rod 46; the second end of the pressing part 44 is in contact with the upper end surface of the upper clamp jaw 48.
[0034] Through the above structure, after the bottom plate 21 of the sampling jig is aligned with the placing groove 11 on the magazine 1, the sliding cover mechanism moves along the outer sliding groove 23 arranged on the first side plate 22 of the sliding cover body to approach the magazine 1 placing the substrate, the clamp jaw assembly of the clamping mechanism clamps the substrate, and then the sliding cover mechanism moves along the outer sliding groove 23 away from the magazine 1 to take out the substrate from the magazine 1.
[0035] Specifically, the bottom plate 21 serves as a support surface to provide stability for the entire sampling jig, the first side plate 22 is arranged on both sides of the bottom plate 21 and along the length direction of the bottom plate 21, and the first side plate 22 is used to support and guide the movement of the sliding cover mechanism. The outer sliding groove 23 is arranged outside the first side plate 22 for sliding of the sliding cover mechanism. The sliding cover mechanism is slidingly connected with the outer sliding groove 23 through the second side plate 32 arranged on both sides of the face plate 31.
[0036] The face plate 31 of the sliding cover mechanism has a cavity in the middle for movement of the L-shaped control part 41 of the clamping assembly in the cavity, the control part 41 is composed of a vertical working part and a horizontal working part, wherein the horizontal working part is accommodated in the cavity, and when the vertical working part is moved, the horizontal working part is also dragged to move. The clamping mechanism includes two symmetrically arranged clamping parts 4. Each clamping part 4 includes a control part 41, a connecting plate 42, a first connecting rod 43, a pressing part 44 and a clamp jaw assembly, and the control part 41 is connected with the pressing part 44 through the first connecting rod 43. The first end of the pressing part 44 is rotationally connected with the control part 41, so that the pressing part 44 can control the action of the clamping part 4 through the first connecting rod 43. The connecting plate 42 is parallelly arranged below the face plate 31 of the sliding cover mechanism, and has a predetermined gap with the face plate 31, the pressing part 44 is rotationally connected on the plane where the thickness of the connecting plate 42 is located, and when the control part 41 pulls the first connecting rod 43, the pressing part 44 connected with the first connecting rod 43 rotates to a state that the second end of the pressing part 44 is pressed downward.
[0037] The pressing part 44 applies pressure to the gripper assembly, causing the upper gripper 48 to move downwards and engage with the lower gripper 47 to complete the clamping. The second end of the pressing part 44 contacts the upper gripper 48 of the gripper assembly, thereby pushing the upper gripper 48 to achieve the clamping function. The first connecting rod 43, connected to the first end of the pressing part 44, is also connected to the connecting plate 42 via the first spring 45, and can automatically reset when the gripping part 4 is released. The second connecting rod 46 connects the upper gripper 48 and the lower gripper 47 of the gripper assembly, and the second spring 49 is sleeved on the outside of the second connecting rod 46 to control the opening and closing of the grippers.
[0038] Once the sliding cover mechanism slides to the desired position, the clamping part 4 clamps or releases the substrate via the pressing part 44. The upper clamping jaw 48 works in coordination with the lower clamping jaw 47 through the action of the second connecting rod 46 and the spring to ensure that the substrate does not shift or fall when placed into the placement slot 11 in the material box 1.
[0039] The clamping mechanism of this utility model has at least a first working state and a second working state. When the clamping mechanism is in the first working state, both the first spring 45 and the second spring 49 of the clamping mechanism are in a non-stretched state, and the clamping mechanism is in a natural static state without external force. The pressing part 44 does not apply pressure to the upper jaw 48, so the upper jaw 48 and the lower jaw 47 do not contact each other, which facilitates the insertion or removal of the substrate. In the first working state, since no external force acts on the jaw assembly, the substrate is not clamped, and the jaw assembly remains in an open state.
[0040] When the clamping mechanism is in the second working state, the control unit 41 moves from both sides towards the middle, thereby dragging the first connecting rod 43 by the control unit 41. The first spring 45 connected to the first connecting rod 43 is stretched. At the same time, the first end of the first connecting rod 43 connected to the pressing part 44 rotates around the center of the pressing part 44. The second end of the pressing part 44 begins to press down on the upper jaw 48, applying pressure so that the upper jaw 48 and the lower jaw 47 can form the ability to clamp the substrate. In the second working state, the jaw assembly can firmly clamp the substrate, preventing it from loosening or slipping, thereby ensuring that the substrate is in a stable clamping state during operation.
[0041] When the upper clamping jaw 48 moves downward, the second spring 49 is also in a stretched state. When the external force applied to the control part 41 is removed, the first spring 45 and the second spring 49 in the stretched state need to be reset. The first spring 45 is reset to drive the first connecting rod 43 and the control part 41 to return to the natural static state, and the pressing part 44 also rotates to stop pressing the upper clamping jaw 48. Since the upper clamping jaw 48 is connected to the second spring 49 in the stretched state at this time, when the pressing force of the pressing part 44 on the upper clamping jaw 48 is lost, the second spring 49 is naturally reset to drive the upper clamping jaw 48 to move upward, and the clamping jaw assembly reenters the open state.
[0042] Through the state conversion of the first spring 45 and the second spring 49, the clamping mechanism can be flexibly switched between two working states, which can not only realize the insertion or removal of the substrate, but also provide sufficient clamping force when the substrate needs to be clamped, so as to ensure that the substrate is clamped stably.
[0043] In the embodiment, the jig body 2 is provided with an inner sliding groove 51 inside the first side plate 22, and a horn opening outward is arranged at one end of the inner sliding groove 51 facing the magazine 1, thereby optimizing the path of substrate extraction. The inner sliding groove 51 provided inside the first side plate 22 of the jig body 2 provides a more stable extraction channel for the substrate extraction, so that the substrate can be smoothly taken out from the magazine 1 during the extraction, and the scratching or collision of the substrate during the extraction process is avoided, thereby reducing the substrate damage caused by improper operation. The inner sliding groove 51 is provided with a horn opening 52 connected thereto at one end close to the magazine 1, so that the substrate can be extracted from the magazine 1 without being stuck or violently collided, thereby protecting the substrate from being damaged.
[0044] In the embodiment, the bottom plate 21 of the jig body 2 is provided with a positioning plate 53 at one end close to the magazine 1, and the positioning plate 53 extends along the length direction of the bottom plate 21. The magazine 1 for storing the substrate has a plurality of placing grooves 11. When the substrate is extracted, the extraction jig is aligned with one placing groove 11, and the positioning plate 53 located at the front end of the bottom plate 21 can be inserted into the placing groove 11 adjacent to the lower placing groove 11, and the positioning plate 53 is in close contact with the upper end surface of the lower placing groove 11, so as to ensure that the jig body 2 is placed horizontally, and the possibility of damage to the substrate during extraction is reduced.
[0045] In the embodiment, the limiting blocks 54 are arranged at both ends of the outer side of the first side plate 22, which are used to limit the movement range of the sliding cover mechanism, prevent excessive displacement, and even slide out of the length range of the first side plate 22. By arranging the limiting blocks 54, the sliding cover mechanism of the extraction jig can be effectively guided during movement to avoid excessive displacement, and the accuracy of the operation steps when the extraction jig extracts the substrate is ensured, so that the extraction process is more stable and smooth, and the risk of substrate damage is reduced.
[0046] In this embodiment, the first side plate 22 of the jig body 2 towards the end face of the magazine 1 is a vertical plane that can be closely attached to the magazine 1, thereby enhancing the close fit between the jig body 2 and the magazine 1 to ensure the stability and accuracy of the substrate during the sampling process. The vertical plane can make the end face of the first side plate 22 completely fit the end face of the magazine 1, forming a stable support plane. During sampling, when the jig body 2 is docked with the magazine 1, the close contact can prevent the jig body 2 from shifting or tilting relative to the magazine 1 during operation, thereby avoiding the position deviation of the substrate during the taking out or putting in process.
[0047] The use mode of the sampling jig for improving substrate loss in the sampling process is as follows:
[0048] Step one, align the front end of the jig body 2 with the placing groove 11 of the magazine 1, thereby ensuring the accurate relative position of the jig body 2 and the magazine 1;
[0049] Step two, move the sliding cover mechanism so that it is located at one end close to the magazine 1, and the sliding cover mechanism moves along the length direction of the jig body 2, so that the sliding cover mechanism can accurately approach the position of the substrate;
[0050] Step three, when the substrate is located in the gap between the upper clamping jaw 48 and the lower clamping jaw 47, the control part 41 moves from both sides to the middle, and the control part 41 moves to drive the pressing part 44 to press downward, so that the upper clamping jaw 48 moves downward to clamp the substrate; the clamping jaw assembly stably clamps the substrate to ensure the stability of the substrate during the sampling process, avoiding the loosening or deviation of the substrate during the movement;
[0051] Step four, under the condition that the clamping mechanism successfully clamps the substrate, control the sliding cover mechanism to move away from one end of the magazine 1, through the movement of the sliding cover mechanism, the sampling jig takes out the substrate from the magazine 1, and the sliding of the sliding cover mechanism enables the sampling jig clamping the substrate to smoothly take out the substrate from the magazine 1, thereby completing the sampling.
[0052] The technical scheme of the present application has been described in combination with the preferred embodiments shown in the drawings, but those skilled in the art can easily understand that the protection scope of the present application is obviously not limited to these specific embodiments. Those skilled in the art can make equivalent changes or replacements to related technical features without deviating from the principles of the present application, and the technical schemes after these changes or replacements will fall within the protection scope of the present application.
