Description

Technical Field

[0001] This utility model relates to the field of shielding testing technology, specifically to a material feeding device for shielding testing. Background Technology

[0002] Shielding testing is a test method used to evaluate the shielding effect of specific areas of electronic devices and systems against electromagnetic interference and radio frequency interference. The shielding test chamber is a key piece of equipment for shielding testing these devices or systems. When testing in the shielding test chamber, materials need to be placed or removed in specific locations to facilitate material detection and unloading.

[0003] For example, patent CN221631467U discloses a signal shielding test box, including a clamping plate. A support plate is first pressed tightly against the side of the object. Then, by pushing the clamping plate, a directional slider slides inside the support plate. The directional slider drives a fixed block to move to one side of the base plate. By pushing a second telescopic rod to contact the base plate, the fixed block pushes the second telescopic rod into the inside of the base plate. The end of the second telescopic rod can extend and retract inside the fixed block. After the support plate is fixed by the second telescopic rod, the fixed block can move within a certain range. Combined with the sliding of the support plate at the top of the base plate, it can extend from multiple directions to fix test objects of different specifications, increasing the flexibility of use. After the test is completed, the materials placed on the track need to be removed manually. The staff needs to frequently operate beside the track to remove the materials one by one. The speed of manual operation is relatively slow and easily affected by human factors.

[0004] To address the aforementioned issues, there is an urgent need for innovative design based on the existing material feeding device for shielding testing. Utility Model Content

[0005] The purpose of this utility model is to provide a material unloading device for shielding testing, so as to solve the problem mentioned in the background art that after the test is completed, the materials placed on the track need to be removed manually. The staff needs to frequently operate next to the track to remove the materials one by one. The speed of manual operation is relatively slow and is easily affected by human factors.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a material feeding device for shielding testing, comprising a test box, a collection box disposed below the test box, a track disposed inside the test box, a side plate mounted on one end of the track, a clamping module mounted on the track, and a placement plate disposed between the two tracks; an abutment plate disposed below the placement plate, a base plate disposed below the abutment plate, and an inclined plate fixedly connected to one side of the abutment plate; and a lifting mechanism for raising and lowering the placement plate disposed on the base plate.

[0007] Furthermore, the lifting mechanism includes a drive motor, which is installed on one side of the top of the base plate. A threaded rod is installed at the output end of the drive motor. The outer wall of the threaded rod is rotatably connected to the abutment plate. Threaded blocks are installed on both sides of the placement plate. The threaded block on one side is threadedly connected to the outer wall of the threaded rod, and a guide rod is slidably connected inside the threaded block on the other side. The guide rod is fixedly connected to the abutment plate.

[0008] Furthermore, guide plates are installed on both sides of the top of the placement plate, an irregularly shaped push plate is slidably connected to one side of the top of the placement plate, sliding columns are fixedly connected to both sides of the irregularly shaped push plate, and guide grooves are opened inside the guide plates, with the sliding columns slidably connected inside the guide grooves.

[0009] Furthermore, the inclined plate is provided with an anti-clogging mechanism to prevent material blockage.

[0010] Furthermore, the anti-clogging mechanism includes a rotating column, which is rotatably connected to one side of the inclined plate. A push rod is installed on the outer wall of the rotating column, and the push rod is slidably connected to the inner bottom wall of the inclined plate. One end of the rotating column is connected to a fixed column via a universal joint. The top of the fixed column and the outer wall of the threaded rod are both fixedly connected to a synchronous pulley, and the two synchronous pulleys are driven by a synchronous belt.

[0011] Furthermore, a groove is provided on the placement plate, and sliding blocks are installed on both sides of the bottom of the irregular push plate, with the sliding blocks slidably connected to the groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This shielding test material feeding device allows the material to slide out and be accurately placed on the placement plate after the test chamber completes material testing. Then, the drive motor drives the threaded rod to rotate, realizing the automatic lifting and lowering of the placement plate, making the placement plate parallel to the inclined plate. During the descent of the placement plate, the cooperation between the sliding columns on both sides of the irregular push plate and the guide groove of the guide plate, as well as the cooperation between the bottom sliding block and the sliding groove of the placement plate, automatically drives the irregular push plate to slide on the placement plate when the sliding column moves to the bend of the guide groove, pushing the material towards the inclined plate, thus realizing the automatic feeding of the material.

[0014] Furthermore, through the transmission of the synchronous pulley and synchronous belt, the power of the drive motor driving the threaded rod to rotate is transmitted to the rotating column, which in turn drives the push rod to rotate on the inclined plate, thus timely pushing the material on the inclined plate and preventing the material from accumulating and blocking at the inclined plate.

[0015] Furthermore, the irregularly shaped pusher plate, through the dual cooperation of sliding column and guide groove, sliding block and chute, can maintain a stable sliding trajectory during the process of the placement plate descending and pushing the material, ensuring the stability and accuracy of the movement of the irregularly shaped pusher plate, so that the material can be smoothly discharged from the placement plate to the inclined plate.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1: Please refer to Figures 1-6This utility model provides the following technical solution: a material feeding device for shielding testing, including a test box 1, a collection box 4 arranged below the test box 1, a track 5 arranged inside the test box 1, a side plate 2 installed at one end of the track 5, a clamping module 6 installed on the track 5, and a placement plate 9 arranged between the two tracks 5; an abutment plate 7 arranged below the placement plate 9, a base plate 3 arranged below the abutment plate 7, and an inclined plate 8 fixedly connected to one side of the abutment plate 7; a lifting mechanism for lifting the placement plate 9 is provided on the base plate 3; the lifting mechanism includes a drive motor 10, and the drive motor 10 is installed on a top of the base plate 3. On one side, a threaded rod 11 is installed at the output end of the drive motor 10. The outer wall of the threaded rod 11 is rotatably connected to the abutment plate 7. Threaded blocks are installed on both sides of the placement plate 9. One threaded block is threadedly connected to the outer wall of the threaded rod 11, and the guide rod 12 is slidably connected inside the threaded block on the other side. The guide rod 12 is fixedly connected to the abutment plate 7. Guide plates 14 are installed on both sides of the top of the placement plate 9. A shaped push plate 13 is slidably connected to one side of the top of the placement plate 9. Sliding columns are fixedly connected to both sides of the shaped push plate 13. A guide groove 19 is opened inside the guide plate 14, and the sliding column is slidably connected inside the guide groove 19.

[0025] A collection box 4 is installed below the test chamber 1 to collect the tested material. After the test chamber 1 completes the material testing, the track 5 and side plate 2 slide out of the test chamber 1. When the material moves into the range of the placement plate 9, the clamping module 6 is released, and the material is placed on the placement plate 9. At this time, the drive motor 10 can be started, and the output end of the drive motor 10 drives the threaded rod 11 to rotate. Threaded blocks are installed on both sides of the placement plate 9. One threaded block is threadedly connected to the outer wall of the threaded rod 11, and the other threaded block is slidably connected to the guide rod 12 fixed on the abutment plate 7. Therefore, when the threaded rod 11 rotates, the threaded rod 11 engages with the threaded block on the placement plate 9, causing the threaded block to move downwards on the threaded rod 11 and simultaneously drive the placement plate 9 downwards. The other threaded block is slidably connected to the guide rod 12 fixed on the abutment plate 7. The rod 12 slides downwards along its outer wall, limiting the vertical movement of the placement plate 9 until it comes into contact with the abutment plate 7. This allows the placement plate 9 to be parallel to the inclined surface of the inclined plate 8. When the placement plate 9 moves downwards, it drives the irregularly shaped push plate 13, which is slidably connected to it, to move downwards. The sliding columns on both sides of the irregularly shaped push plate 13 are slidably connected to the guide groove 19 inside the guide plate 14. At the same time, the sliding blocks 20 on both sides of the bottom of the irregularly shaped push plate 13 are slidably connected to the sliding groove on the placement plate 9. Therefore, when material needs to be discharged, the placement plate 9 moves downwards, driving the irregularly shaped push plate 13 downwards, causing the sliding columns to slide inside the guide groove 19. When the sliding columns move to the bend of the guide groove 19, they drive the irregularly shaped push plate 13 to slide on the placement plate 9, thereby pushing the material toward the inclined plate 8 and achieving rapid material discharge.

[0026] Example 2: Based on Example 1, an anti-clogging mechanism is also disclosed, the specific structure of which is as follows:

[0027] The anti-clogging mechanism includes a rotating column 17, which is rotatably connected to one side of the inclined plate 8. A push rod 18 is installed on the outer wall of the rotating column 17 and is slidably connected to the inner bottom wall of the inclined plate 8. One end of the rotating column 17 is connected to a fixed column 15 via a universal joint. The top of the fixed column 15 and the outer wall of the threaded rod 11 are both fixedly connected to a synchronous wheel 16. The two synchronous wheels 16 are driven by a synchronous belt. A groove is provided on the placement plate 9. Sliding blocks 20 are installed on both sides of the bottom of the irregular push plate 13 and are slidably connected to the groove.

[0028] When the drive motor 10 starts, it drives the threaded rod 11 to rotate. The threaded rod 11 drives the synchronous pulley 16 fixed on it to rotate synchronously. Under the transmission of the synchronous belt, it drives another synchronous pulley 16 to rotate, which in turn drives the fixed column 15 to rotate. The fixed column 15 is connected to the rotating column 17 through a universal joint. Therefore, when the fixed column 15 rotates, it drives the rotating column 17 to rotate synchronously. The rotating column 17 drives the push rod 18 to rotate on the inclined plate 8, thereby pushing the material on the inclined plate 8 and preventing material accumulation and blockage. The groove opened on the placement plate 9 cooperates with the sliding blocks 20 on both sides of the bottom of the irregular push plate 13, providing stable guidance for the sliding of the irregular push plate 13. During the process of the irregular push plate 13 pushing the material, the sliding blocks 20 slide in the groove, ensuring the stability and accuracy of the movement of the irregular push plate 13, so that the material can be smoothly discharged from the placement plate 9 onto the inclined plate 8.
