Description

Technical Field

[0001] The utility model relates to the technical field of copper-clad ceramic substrate detection, and specifically to a copper-clad ceramic substrate positioning and measuring mechanism. Background Art

[0002] The measurement of copper-clad ceramic substrates is mainly divided into contact measurement and non-contact measurement. Among them, contact measurement requires the substrate to be fixed to ensure the accuracy of position and angle. An inductive displacement sensor is used to obtain contour data through the contact between the sensor and the surface of the copper substrate. The data is processed and analyzed by software to calculate whether the flatness of the copper substrate has deviations. It has higher accuracy and stability and is suitable for high-precision measurement; Non-contact measurement uses a laser ranging sensor or an optical image sensor. During the measurement process, the light source needs to be projected onto the positioned surface of the copper substrate. The reflected light is received by the sensor, and the actual position of each point is obtained accordingly, so as to calculate the flatness of the copper substrate. The measurement speed is faster and it is suitable for measuring high-speed moving objects, but it has high requirements on the surface of the object being measured and will be affected by surface quality and light.

[0003] Therefore, no matter which measurement method is used, the substrate needs to be accurately positioned first, and considering the different sizes and measurement requirements of the substrate, as well as its high brittleness, the positioning device must also match the different sizes, and the positioning process must be slow and stable to prevent damage to the substrate.

[0024] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-Figure 5 As shown, a copper-clad ceramic substrate positioning and measuring mechanism includes a sensing and measuring device and a positioning device, wherein the positioning device includes a workbench 10 for placing a substrate body 100, and the workbench 10 has four sequentially connected first side edges 101, a second side edge 102, a third side edge 103 and a fourth side edge 104, and the positioning device also includes a propulsion component 1, a propulsion component 2, a propulsion component 3 and a fixed baffle 4.

[0026] Among them, the propulsion component 1 includes a propulsion plate 11 and a propeller 12, and the propulsion plate 11 is located on the surface of the workbench 10; the propeller 12 is located below the workbench 10, and includes a propulsion rack 121 and a propulsion gear 122 meshing with the propulsion rack 121; a propulsion hole 123 is opened on the surface of the workbench 10, and the propulsion hole 123 is an oblong hole opened along the length direction of the second side 102, and a connecting rod is passed through the propulsion hole 123, and the connecting rod fixes the propulsion plate 11 and the propulsion rack 121; wherein the propulsion rack 121 is arranged along the length direction of the propulsion hole 123, and the propulsion gear 122 is driven to rotate by a driving motor 124.

[0027] By pushing the rack 121 and the pushing gear 122 meshing with it, the rotation of the gear drives the pushing rack to move back and forth, so that the pushing plate 11 fixed to the pushing rack will move evenly and stably. The gear transmission and slow pushing method are adopted to prevent the substrate body 100 from being damaged due to unstable thrust.

[0028] The propulsion assembly 2 2 and the propulsion assembly 3 3 are arranged at the second side 102 and the fourth side 104, respectively, and each includes a propulsion plate 2 21 and a propeller 2 22 capable of causing the propulsion plate 21 to make a reciprocating motion toward the center of the workbench 10; the fixed baffle 4 is fixed at the third side 103 above the workbench 10. Thus, the propulsion assembly 1 1, the propulsion assembly 2 2, the propulsion assembly 3 3 and the fixed baffle 4 surround the substrate body 100 in the middle, wherein the propulsion assembly 1 1, the propulsion assembly 2 2 and the propulsion assembly 3 3 can all be adjusted in position, and adjusting the positions of the three can change the size and position of the space in the middle of the four, so as to match the substrate body 100 of any size and position it.

[0029] During use of the positioning and measuring mechanism, the substrate body 100 is first placed on the surface of the workbench 10, and one edge of the substrate body 100 is brought into contact with the push plate 11. The driving motor 124 then drives the push gear 122 to rotate, so that the push rack 121 meshing with the push gear 122 moves toward the fixed baffle 4, so that the push plate 11 fixed to the push rack 121 moves accordingly, and pushes the substrate body 100 to move synchronously with it until the substrate body 100 contacts the fixed baffle 4 and stops. At this time, the push plate 11 and the fixed baffle 4 together fix the two opposite sides of the substrate body 100.

[0030] Then, after the positioning of the two opposite sides is completed, the propulsion assembly 2 2 and the propulsion assembly 3 3 located on the other two sides are started synchronously, and the propeller 2 22 pushes the propulsion plate 2 21 to move toward the center of the workbench 10 until it contacts the other two opposite sides of the substrate body 100 and stops. At this time, the positioning and measuring mechanism completely positions the central substrate body 100, and starts the sensing and measuring device to detect the substrate body 100. Since the position of the fixed baffle 4 remains unchanged, the sensing and measuring device can set the coordinate parameters for measurement based on the position of the fixed baffle 4. After the measurement is completed, the propeller 12 and the propeller 2 22 both work in the reverse direction to reset the propulsion plate 11 and the two propulsion plates 21, and then remove the detected substrate body 100 and place it in the specified position.

[0031] like Figure 3 As shown, the second pusher plate 21 is a bent plate, including a flat plate 1 211 and a flat plate 212 at a certain angle, the flat plate 1 211 is parallel to the surface of the workbench 10, the flat plate 212 is connected to the propeller 22, and the propeller 22 is a telescopic oil cylinder. A horizontal slide 213 is fixed to the bottom of the flat plate 212, a guide slide 214 and a guide rail 215 matching the guide slide 214 are fixed to the bottom of the horizontal slide 213, the guide rail 215 is arranged along the length direction of the first side 101, and the propeller 22 is connected to the horizontal slide 213.

[0032] Therefore, when the thruster 22 needs to move forward or backward toward the workbench 10, the telescopic cylinder can drive the horizontal slide 213 to move back and forth along the guide rail 215. The flat plate 1 211 is used to contact and fix the substrate body 100. The flat plate 212 is connected to the thruster 22, which avoids the driving force directly acting on the flat plate 1 211, resulting in excessive force to damage the substrate body 100. The guide slide block 214 and the guide rail 215 are also used to further ensure the smooth operation of the thruster plate 21.

[0033] like Figure 4 As shown, the propulsion rack 121 is also connected to the workbench 10 through a guide rail 1211, thereby ensuring smoother operation between the propulsion rack 121 and the workbench 10. In addition, the propulsion gear 122 is rotatably connected to the workbench 10, thereby ensuring the stability of the gear operation.

[0034] like Figure 5As shown, a crash strip 216 is fixed on the horizontal slide 213, and the crash strip 216 is arranged along the length direction of the first side 101, and an adjustment hole 2160 arranged in the same direction is opened in the middle thereof, and the crash strip 216 is fixed to the horizontal slide 213 by a bolt 2161 inserted in the adjustment hole 2160. The crash strip 216 can adjust the length of its extension toward the outside of the horizontal slide 213 through the bolt 2161 and the adjustment hole 2160, and the length is changed according to different substrate sizes to ensure that when the positioning is completed and the push plate 21 is relatively fixed to the substrate body 100, the crash strip 216 just contacts and abuts against the flat plate 212 on the other side thereof, thereby preventing the push plate 21 from damaging the substrate body 100 when it rushes forward due to inertia. In order to facilitate the adjustment of the length of the crash strip 216, a receiving hole 217 is opened on the flat plate 212 to allow one end of the crash strip 216 extending out of the workbench 10 to pass through.

[0035] Among them, in order to prevent mutual interference between the pushing plate 11 and the pushing plate 2 21, the pushing plate 2 21 should be higher than the pushing plate 11. However, since the thickness of the substrate body 100 is relatively thin, the pushing plate 1 11 and the pushing plate 2 21 should be as close as possible to the workbench 10, so as to ensure that the working height of the two can match the thickness of the substrate body 100.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
