Description

Technical Field

[0001] This utility model relates to the field of MLCC block testing technology, specifically to an MLCC block multi-point synchronous testing device. Background Technology

[0002] MLCC, also known as multilayer ceramic chip capacitor, is made by stacking ceramic dielectric films with printed electrodes (internal electrodes) in a staggered manner, sintering them at high temperature in one go to form a ceramic chip, and then sealing the two ends of the chip with metal layers (external electrodes), thus forming a monolithic structure, hence the name monolithic capacitor. There are many types of MLCC, which can be classified into three main categories: temperature characteristics, materials, and manufacturing processes.

[0003] In the existing technology, when testing MLCC blocks, several MLCC blocks need to be glued to the top of a tray, and then the tray and MLCC blocks are sent to the testing equipment for testing. However, the tray is not fixed during testing, and the tray moves during testing, resulting in a decrease in testing accuracy.

[0004] Therefore, a multi-point synchronous testing device for MLCC blocks is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a multi-point synchronous testing device for MLCC blocks, which solves the problem of decreased testing accuracy caused by the movement of the tray during testing due to the lack of fixation of the tray.

[0006] To achieve the above objectives, the present invention provides the following technical solution: including a base, wherein a limiting mechanism is assembled at the bottom of the base, and a bar block body is assembled on the base;

[0007] The limiting mechanism includes a linear motor, a slider, a threaded rod, a limiting rod, a baffle, a knob, a moving plate, a first hydraulic chamber, a first hydraulic rod, and a limiting block. The linear motor is mounted on the upper surface of the external operating platform. The slider is threadedly connected to the outer wall of the output end of the linear motor and is fixedly connected to the lower surface of the base. The threaded rod is rotatably connected to the side of the base via a bearing. The limiting rod is fixedly connected to the side of the base. The baffle is fixedly connected to the side of the limiting rod. The knob is fixedly connected to the side of the threaded rod. The moving plate is threadedly connected to the outer wall of the threaded rod. The first hydraulic chamber is fixedly connected to the upper surface of the moving plate. The first hydraulic rod is slidably connected to one end inside the first hydraulic chamber via a piston. The limiting block is fixedly connected to the side of the first hydraulic rod. A drive assembly for moving the first hydraulic rod is assembled at the bottom of the base.

[0008] Preferably, the drive assembly includes a connecting hose, a second hydraulic chamber, a second hydraulic rod, and a limiting plate. The connecting hose is fixedly connected to the side of the first hydraulic chamber, the second hydraulic chamber is fixedly connected to the lower surface of the base, the second hydraulic rod is slidably connected to one end inside the second hydraulic chamber via a piston, and the limiting plate is fixedly connected to the front of the linear motor.

[0009] Preferably, the end of the connecting hose away from the first hydraulic chamber is fixedly connected to the side of the second hydraulic chamber, the threaded rod movably passes through the baffle, and the outer wall of the limiting rod is provided with a scale for easy adjustment of the distance of the moving plate.

[0010] Preferably, the limiting plate includes an inclined surface and a straight surface, the inclined surface being formed on the front side of the limiting plate, and the straight surface being formed on the front side of the limiting plate.

[0011] Preferably, the second hydraulic rod is slidably connected to the front of the limiting plate, and a spring is movably sleeved on the outer wall of the second hydraulic rod.

[0012] Preferably, one end of the spring is fixedly connected to the front of the second hydraulic chamber, and the end of the spring away from the second hydraulic chamber is fixedly connected to the outer wall of the second hydraulic rod.

[0013] Preferably, the top of the base is equipped with a detection mechanism, which includes a connecting plate, a contact displacement sensor, and a pulley. The connecting plate is fixedly connected to the side of the external operating table, the contact displacement sensor is fixedly connected to the upper surface of the connecting plate, and the pulley is fixedly connected to the bottom of the output end of the contact displacement sensor.

[0014] Compared with the prior art, this utility model provides a multi-point synchronous testing device for MLCC blocks, which has the following beneficial effects:

[0015] 1. When the linear motor drives the base to move, the second hydraulic rod automatically slides along the inclined and straight surfaces of the limiting plate, squeezing the second hydraulic rod to push the limiting block to mechanically clamp the bar block body simultaneously, preventing the pallet from shifting during the detection process and causing a decrease in detection accuracy.

[0016] 2. By rotating the knob to drive the threaded rod, the lateral position of the moving plate can be precisely adjusted. Combined with the flexible drive of the hydraulic components, it can adapt to the different sizes and arrangement densities of the bars, and achieve precise adjustment of the scale.

[0017] Third, during the base movement, multiple sets of contact displacement sensors scan the flatness of the block surface in real time through pulleys, completing multi-point data acquisition at one time, which improves the detection efficiency by several times compared with single-point sensors.

[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

[0025] See Figure 1 - Figure 4 This embodiment provides a multi-point synchronous testing device for MLCC blocks, including a base 1, a limit mechanism 2 mounted on the bottom of the base 1, and a block body 4 mounted on the base 1.

[0026] The limiting mechanism 2 includes a linear motor 21, a slider 22, a threaded rod 23, a limiting rod 24, a baffle 25, a knob 26, a moving plate 27, a first hydraulic chamber 28, a first hydraulic rod 29, and a limiting block 210. The linear motor 21 is fixedly connected to the upper surface of the external operating platform. The slider 22 is threadedly connected to the outer wall of the output end of the linear motor 21 and fixedly connected to the lower surface of the base 1. The threaded rod 23 is rotatably connected to the side of the base 1 via a bearing. The limiting rod 24 is fixedly connected to the side of the base 1. The baffle 25 is fixedly connected to the side of the limiting rod 24. The knob 26 is fixedly connected to the side of the threaded rod 23. The moving plate 27 is threadedly connected to the outer wall of the threaded rod 23. The first hydraulic chamber 28 is fixedly connected to the upper surface of the moving plate 27. The first hydraulic rod 29 is slidably connected to one end inside the first hydraulic chamber 28 via a piston. The limiting block 210 is fixedly connected to the side of the first hydraulic rod 29. The bottom of the base 1 is equipped with a drive assembly for moving the first hydraulic rod 29.

[0027] By rotating the knob 26, the knob 26 drives the threaded rod 23 to rotate, and the threaded rod 23 drives the moving plate 27 to move to the right. Since the distance the first hydraulic rod 29 moves is fixed, the movement of the moving plate 27 is used to deal with the bar blocks of different sizes. The drive assembly drives the first hydraulic rod 29 to move to the right, and the first hydraulic rod 29 drives the limit block 210 to limit the bar block body 4.

[0028] See Figure 2 The drive assembly includes a connecting hose 211, a second hydraulic chamber 212, a second hydraulic rod 213, and a limiting plate 214. The connecting hose 211 is fixedly connected to the side of the first hydraulic chamber 28, the second hydraulic chamber 212 is fixedly connected to the lower surface of the base 1, the second hydraulic rod 213 is slidably connected to one end inside the second hydraulic chamber 212 via a piston, the limiting plate 214 is fixedly connected to the front of the linear motor 21, and the end of the connecting hose 211 away from the first hydraulic chamber 28 is fixedly connected to the side of the second hydraulic chamber 212. The guide rod 23 moves through the baffle 25. The outer wall of the limiting rod 24 is provided with a scale for easy adjustment of the distance of the moving plate 27. The scale allows the worker to adjust the distance of the moving plate 27 more accurately. The limiting plate 214 includes an inclined surface 2141 and a flat surface 2142. The inclined surface 2141 is opened on the front of the limiting plate 214, and the flat surface 2142 is opened on the front of the limiting plate 214. The second hydraulic rod 213 is slidably connected to the front of the limiting plate 214, and a spring is movably sleeved on the outer wall of the second hydraulic rod 213.

[0029] The linear motor 21 is started, which drives the slider 22 to move from right to left. The slider 22 drives the second hydraulic chamber 212 and the second hydraulic rod 213 to move to the left. The second hydraulic rod 213 slides on the front of the inclined surface 2141 of the limiting plate 214. As the slider 22 continues to move to the left, the second hydraulic rod 213 will slide to the front of the flat surface 2142. The flat surface 2142 will squeeze the second hydraulic rod 213, and the spring will be squeezed. The second hydraulic rod 213 drives the piston to move forward. The piston squeezes the hydraulic oil to converge at the connecting hose 211 and the first hydraulic chamber 28, thereby driving the first hydraulic rod 29 to move to the right. The first hydraulic rod 29 drives the limiting block 210 to limit the bar block body 4.

[0030] One end of the spring is fixedly connected to the front of the second hydraulic chamber 212, and the other end of the spring away from the second hydraulic chamber 212 is fixedly connected to the outer wall of the second hydraulic rod 213.

[0031] See Figure 1 and Figure 3 The base 1 is equipped with a detection mechanism 3 on its top. The detection mechanism 3 includes a connecting plate 31, a contact displacement sensor 32, and a pulley 33. The connecting plate 31 is fixedly connected to the side of the external operating table, the contact displacement sensor 32 is fixedly connected to the upper surface of the connecting plate 31, and the pulley 33 is fixedly connected to the bottom of the output end of the contact displacement sensor 32.

[0032] When the base 1 drives the bar block body 4 to move to the left, it slides on the top of the bar block body 4 via the pulley 33. If the bar block body 4 is uneven, regardless of whether the pulley 33 is going down or up, the data of going down and going up will be transmitted to the contact displacement sensor 32. The detection efficiency of the bar block body 4 is improved by using multiple sets of contact displacement sensors 32 to detect the bar block body 4. The output of the contact displacement sensor 32 and the displacement of the pulley 33 are converted into electrical signals by internal inductance or optical encoder. This technology is existing technology and will not be described in detail.

[0033] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
