Description

Technical Field

[0001] The utility model relates to the technical field of substrate detection, in particular to a ceramic substrate flatness detection device. Background Art

[0002] Ceramic substrate refers to a special process board in which copper foil is directly bonded to the surface of an alumina or aluminum nitride ceramic substrate at high temperature. Ceramic substrate has become the basic material for high-power power electronic circuit structure technology and interconnection technology. The flatness of the ceramic substrate needs to be ensured during use. In order to ensure the quality of the substrate, its flatness often needs to be tested.

[0003] For example, a substrate flatness detection device disclosed in publication number CN217210730U places the substrate on a pallet that can carry the substrate, pushes the push-pull rod down through a push-pull ring, and the push-pull rod can drive the detection plate to descend. The detection plate transfers gravity to the touch switch, which can make the touch switch apply pressure to the surface of the substrate. When the flatness of the substrate is good, the five touch switches are in contact with the surface of the substrate and can turn on the five lamp beads, thereby completing the flatness detection work.

[0004] However, when the flatness detection device is in use, the push-pull rod can drive the detection plate to descend, and the detection plate transmits gravity to the touch switch, and the lower end of the detection plate is in contact with the surface of the substrate through five touch switches. When the thickness of the substrate is different, the user may not be able to control the force when manually controlling the push-pull rod to drive the detection plate to descend, which may cause the contact switch to come into hard contact with the surface of the substrate and easily cause damage. In view of this, we propose a ceramic substrate flatness detection device. Summary of the invention

[0005] The purpose of the utility model is to provide a ceramic substrate flatness detection device to solve the problems raised in the above background technology.

[0006] To achieve the above purpose, the utility model provides the following technical solutions: a ceramic substrate flatness detection device, comprising a support plate and a top plate, wherein the four corners of the top of the support plate are fixedly connected to the four corners of the bottom of the top plate through columns, a push-pull rod runs through the middle of the support plate, and an adjustment structure is arranged above the support plate, and the adjustment structure comprises:

[0007] A fixing frame, the fixing frame is fixedly mounted at the lower end of the push-pull rod, a cavity is opened inside the fixing frame, a positioning cylinder is fixedly penetrated through the middle of the inner wall of the cavity, a positioning block is slidably connected to the inner wall of the positioning cylinder, a protective plate is fixedly mounted at the lower end of the positioning block, and a detection plate is arranged at the lower end of the protective plate;

[0008] A slider, the slider is slidably connected to the inner wall of the cavity, the side wall of the slider is rotatably connected to one end of a screw through a sleeve, the other end of the screw penetrates the side wall of the fixing frame, the side wall of the fixing frame is fixedly installed with a sleeve, the screw is connected to the internal thread of the sleeve, one end of a connecting rod is hinged on the side wall of the slider, the other end of the connecting rod is hinged to the upper end of the positioning block, and a protective structure is provided on the upper end of the detection plate.

[0009] Preferably, the protective structure includes a slot opened at the lower end of the protective plate, a damper is fixedly installed on the inner wall of the slot, a slide is fixedly installed on the lower end of the damper, a support rod is fixedly installed on the lower end of the slide, and the lower end of the support rod is fixedly connected to the upper end of the detection plate.

[0010] Preferably, L-shaped plates are fixedly mounted on both sides of the lower end of the fixing frame, the L-shaped plates are in contact with the surface of the detection plate, and the side walls of the detection plate are slidably connected to the inner walls of the L-shaped plates.

[0011] Preferably, the protective structure is provided in three groups, and the three groups of the protective structure are arranged in a linear array at the lower end of the protective plate.

[0012] Preferably, a handle is fixedly mounted on one end of the screw rod located outside the fixing frame.

[0013] Preferably, a pull ring is fixedly mounted on the upper end of the push-pull rod, and scale lines are provided on the side wall of the positioning block.

[0014] Compared with the prior art, the utility model provides a ceramic substrate flatness detection device, which has the following beneficial effects:

[0015] 1. The ceramic substrate flatness detection equipment is convenient for adjusting the height of the detection plate by setting an adjustment structure. There is no need for manual observation when placing the push-pull rod. When the thickness of the substrate detected at the upper end of the pallet is different, the user can drive the slider to move on the inner wall of the cavity by rotating the screw, and the positioning block is driven to move up and down inside the positioning cylinder by the movement of the slider, and the detection plate is driven to move by the movement of the positioning block. Then, when performing the detection, it is only necessary to completely lower the push-pull plate, so as to avoid the contact switch at the lower end of the detection plate from hard contact with the surface of the substrate, which may easily cause damage.

[0016] 2. The ceramic substrate flatness detection equipment is provided with a protective structure so as to provide a certain degree of buffering protection when the contact switch at the lower end of the detection plate contacts the substrate surface. When the lower end of the detection plate contacts the substrate surface, if the detection plate moves at a faster speed at this time, the detection plate will move upward to squeeze the support rod. At this time, the support rod can move upward to squeeze the damper in the inner cavity of the notch for buffering protection, thereby further improving the use effect of the device.

DETAILED DESCRIPTION

[0023] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: a ceramic substrate flatness detection device, including a support plate 1 and a top plate 2, the four corners of the top of the support plate 1 are fixedly connected to the four corners of the bottom of the top plate 2 through columns 5, a push-pull rod 6 is passed through the middle of the support plate 1, an adjustment structure 3 is arranged above the support plate 1, and the adjustment structure 3 includes a fixing frame 31 fixedly installed at the lower end of the push-pull rod 6, a cavity 32 is opened inside the fixing frame 31, a positioning cylinder 33 is fixedly passed through the middle of the inner wall of the cavity 32, and a positioning block 34 is slidably connected to the inner wall of the positioning cylinder 33 A protective plate 35 is fixedly installed at the lower end of the positioning block 34, and a detection plate 36 is arranged at the lower end of the protective plate 35. A slider 37 is slidably connected to the inner wall of the cavity 32. The side wall of the slider 37 is rotatably connected to one end of a screw 38 through a shaft sleeve. The other end of the screw 38 penetrates the side wall of the fixing frame 31. A sleeve 39 is fixedly installed on the side wall of the fixing frame 31. The screw 38 is connected to the internal thread of the sleeve 39. One end of a connecting rod 310 is hinged to the side wall of the slider 37. The other end of the connecting rod 310 is hinged to the upper end of the positioning block 34. A protective structure 4 is arranged on the upper end of the detection plate 36.

[0024] Specifically, the adjustment structure 3 of the technical solution of the utility model includes: a fixing frame 31, a cavity 32, a positioning cylinder 33, a positioning block 34, a protective plate 35, a detection plate 36, a slider 37, a screw 38, a sleeve 39, and a connecting rod 310.

[0025] In one embodiment of the utility model, an adjustment structure 3 is provided to facilitate the adjustment of the height of the detection plate 36, thereby eliminating the need for manual observation when placing the push-pull rod 6, and by providing matching magnetic blocks at the lower end of the top plate 2 and the upper end of the fixing frame 31, the fixing frame 31 can be limited. When performing the detection work, the staff first places the substrate on the pallet 1, which can carry the substrate, and then the user can adjust the position of the detection plate 36 according to the different heights of the substrates in the same batch.

[0026] For example, when the thickness of the substrate to be detected this time is higher than the previous thickness, the user can turn the handle 8 to work, and the rotation of the handle 8 drives the screw 38 to rotate. At this time, the screw 38 rotates inside the sleeve 39 to move outward. The movement of the screw 38 outward will drive the slider 37 to move, and the movement of the slider 37 drives the connecting rod 310 of its side wall to move. The movement of the connecting rod 310 drives the positioning block 34 hinged thereto to move upward inside the positioning cylinder 33, so that the movement of the positioning block 34 drives the detection plate 36 at its lower end to move. The moving distance of the detection plate 36 is adapted to the height of the substrate. The height of the substrate can be detected by any detection ruler or other device. The moving height of the detection plate 36 can be adjusted by the scale line 9 on the side wall of the positioning block 34, thereby avoiding the contact switch at the lower end of the detection plate 36 from hard contact with the substrate surface, which is easy to cause damage.

[0027] Then, the push-pull rod 6 is pushed downward to move, and the push-pull rod 6 drives the fixing frame 31 and the detection plate 36 to descend, and the detection plate 36 transfers gravity to the touch switch, so that the touch switch can apply pressure to the surface of the substrate to complete the detection work.

[0028] By setting up the protective structure 4, it is convenient to provide a certain degree of buffering protection for the contact switch at the lower end of the detection plate 36 when it contacts the surface of the substrate. When the lower end of the detection plate 36 contacts the surface of the substrate, if the movement speed of the detection plate 36 is faster at this time, the detection plate 36 will move upward to squeeze the support rod 44. At this time, the support rod 44 can move upward to squeeze the damper 42 in the inner cavity of the notch 41 for buffering protection, thereby further improving the use effect of the device.

[0029] Please continue reading Figure 1-Figure 5The protective structure 4 includes a slot 41 opened at the lower end of the protective plate 35, a damper 42 is fixedly installed on the inner wall of the slot 41, a slide plate 43 is fixedly installed on the lower end of the damper 42, a support rod 44 is fixedly installed on the lower end of the slide plate 43, and the lower end of the support rod 44 is fixedly connected to the upper end of the detection plate 36.

The protective structure 4 is provided with three groups, and the three groups of protective structures 4 are arranged at the lower end of the protective plate 35 in a linear array form. A handle 8 is fixedly installed at one end of the screw 38 located on the outer side of the fixed frame 31, a pull ring is fixedly installed on the upper end of the push-pull rod 6, and a scale line 9 is provided on the side wall of the positioning block 34.

[0030] When working, first place the substrate on the support plate 1, then the user measures the height of the substrate by means of a measuring ruler or other device, and then the user can move the handle 8 to work, the rotation of the handle 8 drives the screw rod 38 to rotate, at this time the screw rod 38 rotates inside the sleeve 39 to move outward, the outward movement of the screw rod 38 drives the slider 37 to move, the movement of the slider 37 drives the connecting rod 310 of its side wall to move, the movement of the connecting rod 310 drives the positioning block 34 hinged thereto to move upward inside the positioning tube 33, thereby driving the detection plate 36 at the lower end thereof to move through the movement of the positioning block 34 Move, the moving distance of the detection plate 36 is adapted to the height of the substrate, and then the push-pull rod 6 is pushed to move. At this time, the push-pull rod 6 drives the fixing frame 31 and the detection plate 36 to descend, and the detection plate 36 transfers gravity to the touch switch, which can enable the touch switch to apply pressure to the surface of the substrate to complete the detection work, and when the lower end of the detection plate 36 contacts the surface of the substrate, if the movement speed of the detection plate 36 is faster at this time, the detection plate 36 will move upward to squeeze the support rod 44.
