Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, in particular to an SMT elastic gasket resilience detection device. Background Technique

[0002] The SMT elastic gasket is a component used in surface mount technology. SMT is a technology for installing electronic components. It directly installs components on the surface of a printed circuit board (PCB) instead of connecting circuits by inserting holes through the PCB. Nowadays, when the SMT elastic gasket is put into use, its resilience needs to be detected to ensure that its quality meets the standard and prevent inferior products from flowing out, which may affect product sales. When detecting the resilience of the SMT elastic gasket, usually, the SMT elastic gasket is pressured, and when the pressure reaches an appropriate level, the pressure application stops, and with the cooperation of a pressure sensor, the detection of the resilience of the SMT elastic gasket is completed.

[0003] However, common detection equipment has the problem of unstable pressure application during the detection process, resulting in uneven stress on the SMT elastic gasket during compression, thus affecting the detection results. And there is a risk of damage during the detection process, causing its fragments to fly around, which is likely to accidentally injure the detection personnel. In view of this, we propose an SMT elastic gasket resilience detection device. Content of the Utility Model

[0004] The purpose of the utility model is to propose an SMT elastic gasket resilience detection device aiming at the problems existing in the background technique.

A shielding component for closing the opening of the protective cover is installed at the opening of the front view wall of the protective cover. A first magnet block for positioning the shielding component is installed on one side wall of the protective cover. A centralized box for collecting debris is arranged inside the base.

[0006] Preferably, the detection component includes a first movable plate. A pressure sensor and a spring are connected to the bottom wall of the first movable plate. The bottom ends of a plurality of the springs are connected to a second movable plate.

[0007] Preferably, a T-shaped stabilizing rod is welded to the top of the second movable plate. Slide holes are opened on the top wall of the protective cover. A plurality of the T-shaped stabilizing rods are respectively arranged in the slide holes corresponding in position.

[0008] Preferably, the shielding component includes a baffle plate. A limiting strip and a limiting block are welded on the back wall of the baffle plate. First limiting chutes are formed on the front-facing walls of the shield and the base, and the limiting strip and the limiting block are respectively arranged in the first limiting chutes at corresponding positions.

[0009] Preferably, a lever is welded on the back wall of the baffle plate, and the cleaning surface of the lever is in close contact with the top wall of the base.

[0010] Preferably, a hidden groove is formed on the inner wall of one side of the shield, and the lever is arranged in the hidden groove.

[0012] Preferably, a second limiting chute is formed in the base, and the centralized box is arranged in the second limiting chute.

[0013] Compared with the prior art, the utility model has the following beneficial technical effects:

[0014] In the utility model, by placing the SMT elastic gasket on the base, pulling the baffle plate to close the front-facing opening of the base, starting the hydraulic cylinder to drive the first movable plate to descend, so that the second movable plate comes into contact with the SMT elastic gasket in advance, achieving the purpose of positioning it and preventing it from moving during the detection process. At the same time, under the elastic action of the spring, the first movable plate drives the pressure sensor and the spring to descend. When the pressure sensor contacts the second movable plate, the SMT elastic gasket can be pressed simultaneously, thereby completing the detection of its resilience. And under the guiding action of the T-shaped stabilizing rod, it is beneficial to prevent the second movable plate from moving during the pressing process and avoid affecting the accuracy of the detection result. If it is damaged during the detection process, under the protection of the shield and the shielding component, it can prevent the fragments from scattering around and hurting the staff, improving the safety during the detection. And during the process of pulling the baffle plate, the lever can be driven to move, completing the cleaning of the top of the base, facilitating the cleaning of the fragments into the centralized box, which is beneficial for subsequent processing and preventing it from affecting the subsequent detection work.

[0020] Embodiment

[0021] As Figures 1-3 shown, an SMT elastic gasket resilience detection device proposed by the present utility model includes a base 1 and a controller 9. A shield 2 is fixedly installed on the top wall of the base 1. The base 1 is used to support the SMT elastic gasket, and the shield 2 plays a protective role for the SMT elastic gasket, which is beneficial to avoid the fragments flying around when the SMT elastic gasket is damaged during the detection process, thus accidentally injuring the staff; the controller 9 is fixedly installed on the other side wall of the shield 2; a centralized box 8 is arranged in the second limiting chute opened on the base 1, and the wall of the opening of the centralized box 8 is flush with the top wall of the base 1, which is convenient for collecting the debris on the base 1.

[0022] Furthermore, a detection component 3 for facilitating the detection of the SMT elastic gasket is arranged in the shield 2. The detection component 3 includes a first movable plate 31. A hydraulic cylinder 4 is fixedly installed on the top wall of the shield 2. The output end of the hydraulic cylinder 4 penetrates through the sliding hole in the middle position of the top wall of the shield 2 and is fixedly connected to the top wall of the first movable plate 31 arranged in the shield 2, which is convenient for driving the first movable plate 31 to move up and down; a pressure sensor 32 and a plurality of springs 33 are both fixedly installed on the bottom wall of the first movable plate 31, and the bottom ends of the plurality of springs 33 are fixedly connected to the top wall of the second movable plate 34, so that when the hydraulic cylinder 4 pushes the first movable plate 31 to press down, the SMT elastic gasket can be contacted in advance through the second movable plate 34 to complete its positioning, preventing the SMT elastic gasket from moving during the subsequent detection process and affecting the accuracy of the detection result. At the same time, with the arrangement of the springs 33, the first movable plate 31 can drive the pressure sensor 32 to continuously press down. When the pressure sensor 32 contacts the second movable plate 34, the pressure sensor 32 and the second movable plate 34 cooperate to achieve the resilience detection of the SMT elastic gasket; the bottom ends of a plurality of T-shaped stabilizer bars 35 respectively penetrate through the corresponding sliding holes and are fixedly connected to the top wall of the second movable plate 34. When the second movable plate 34 presses down, the cooperation of the plurality of T-shaped stabilizer bars 35 and the sliding holes can reduce the risk of shaking or tilting of the second movable plate 34 during the pressing process, so as to achieve the purpose of uniform pressure application and improve the accuracy of the detection result.

[0023] Furthermore, a shielding assembly 6 for facilitating the closing of the opening of the shield 2 is installed at the opening of the shield 2 facing the wall body. The shielding assembly 6 includes a baffle 61 which is arranged at the opening of the shield 2 facing the wall body to shield the opening, thereby preventing debris from splashing around through the opening of the shield 2; a first magnet block 7 is fixedly installed on one side wall of the shield 2, and a second magnet block 65 is fixedly installed on one side wall of the baffle 61. When the baffle 61 is in a state of closing the shield 2, the position of the second magnet block 65 corresponds to the position of the first magnet block 7, and the two are magnetically attracted to each other, so as to achieve the purpose of positioning the baffle 61 and prevent it from moving, reducing the protection effect; a limiting strip 62, a limiting block 63 and a lever 64 are all welded on the back wall of the baffle 61. The limiting strip 62 and the limiting block 63 are respectively arranged in the first limiting chutes opened on the base 1 and the wall body of the shield 2 facing forward. Through the cooperation of the two first limiting chutes with the limiting strip 62 and the limiting block 63, it plays a guiding role for the moving baffle 61. At the same time, with the setting of the limiting block 63, it is beneficial to prevent the baffle 61 from separating from the base 1 and the shield 2 during the moving process, avoiding affecting the subsequent reset use; the lever 64 is arranged in a hidden groove opened on the inner wall of one side of the shield 2. When the second magnet block 65 corresponds to the position of the first magnet block 7, the lever 64 is in the hidden groove. Through the shielding of the hidden groove, it avoids affecting the resilience detection of the SMT elastic gasket. When the baffle 61 is pulled, the lever 64 can drive the debris at the top of the base 1 to move and guide it into the collection box 8 for collection, avoiding the accumulation of debris at the top of the base 1 and affecting the subsequent resilience detection of the SMT elastic gasket.
