DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0024] like Figure 1-Figure 6 As shown, a ceramic substrate testing mechanism proposed in an embodiment of the present application includes a frame 1, on which a detection component 2 is installed. The detection component 2 is a prior art, including a laser probe, a telescopic mechanism, a wire, etc. The distinguishing technical features of the present application are as follows: the frame 1 is provided with a bearing plate 3 which moves back and forth in a direction toward the detection component 2, the bearing plate 3 is connected to the frame 1 by the cooperation of a slide rail and a slider, so that the bearing plate 3 can slide on the frame 1, wherein the sliding power of the bearing plate 3 comes from a pneumatic push rod 8, the piston rod of the pneumatic push rod 8 is connected to the bearing plate 3, and is used to push the bearing plate 3 to reciprocate linearly, the bearing plate 3 is provided with a lever 7 which separates the ceramic substrate from the bearing plate 3 after detection, a loading frame 4 is installed on the frame 1, a storage rack 5 is detachably connected to the loading frame 4, a discharge channel is provided between the loading frame 4 and the storage rack 5, and a pushing component 6 is provided on the loading frame 4 for pushing the ceramic substrate in the storage rack 5 into the bearing plate 3 through the discharge channel;

[0025] Based on the above disclosed content, the position of the carrier plate 3 relative to the frame 1 has two key points. One is the detection station where the carrier plate 3 is located below the laser probe, and the other is the loading and unloading station where the loading frame 4 is located. That is to say, when the carrier plate 3 is in the loading and unloading station, the push component 6, the loading frame 4 and the storage rack 5 cooperate to push the single ceramic substrate from the discharge channel to the carrier plate 3 to complete the loading work. After the ceramic substrate is inspected, the unloading work of the ceramic substrate is completed by the lever 7 during the process from the inspection station to the loading and unloading station. Therefore, compared with the prior art, the present application can complete the loading and unloading work of the ceramic substrate, which is helpful for the batch inspection of the ceramic substrate. A conveying component 9 is installed on the carrier plate 3, and the conveying component 9 is a belt transport component for transporting the unloaded ceramic substrate to the corresponding position.

[0026] like Figure 2As shown, in some embodiments, the top of the loading frame 4 is constructed with two notch plates 10, and two parallel sides of the storage rack 5 are installed with plug blocks 11, which are inserted into the corresponding notch plates 10. A spring sheet 12 is embedded and installed inside the notch plates 10. The ceramic substrates in the storage rack 5 are stacked in a vertical direction. When the ceramic substrate at the bottom is pushed out of the discharge channel by the pushing component 6, the ceramic substrate will move down one position as a whole under the action of gravity, and when one After the inspection of the ceramic substrates in the storage rack 5 is completed, the storage rack 5 can be directly replaced. The storage rack 5 and the loading frame 4 are connected by inserting the plug block 11 into the slot plate 10. During the insertion of the plug block 11, the spring sheet 12 is squeezed to cause the spring sheet 12 to deform. When the plug block 11 is fully inserted, the spring sheet 12 is reset to form a restriction on the storage rack 5, thereby improving the stability of the storage rack 5. When the storage rack 5 needs to be separated from the loading frame 4, the storage rack 5 can be directly pulled out by applying force.

[0027] like Figure 5 and Figure 6 As shown, in some embodiments, two parallel sides of the material storage rack 5 are constructed with a discharge port 13, the bottom of the loading frame 4 is open and a plurality of shaft rods 14 are installed in an array, two parallel sides of the loading frame 4 are constructed with notches, and a discharge channel is formed by the notches and the discharge port 13, wherein the bottom of the material storage rack 5 is not a completely open structure, which is to prevent the ceramic substrate from falling directly through the bottom of the material storage rack 5, and the ceramic substrate is translated through the discharge port 13 on the material storage rack 5. Similarly, in order to meet the translational movement of the ceramic substrate, the loading frame 4 is also constructed with a notch structure, and the shaft rod 14 is used in the design considering that the ceramic substrate is usually thin, light and small in size, and in order to avoid the ceramic substrate from fitting against the bottom of the loading frame 4, the shaft rod 14 is used to reduce the contact area and facilitate the movement of the ceramic substrate.

[0028] like Figure 2 As shown, in some embodiments, the pushing component 6 includes a bracket 601 installed on the loading frame 4, the bracket 601 is elastically connected to a push plate 602 that slides with the bracket 601, the push plate 602 is installed with a mounting block 603, the mounting block 603 is installed with an iron block 604, and the loading frame 4 is installed with an electromagnet 605, wherein the opening and closing of the electromagnet 605 can be achieved by a travel switch and a relay. When the carrier plate 3 moves to the loading station, the travel switch is triggered to issue a start command, and the relay controls the electromagnet 605 to be energized to realize the iron block 604 approaching the electromagnet 605, completing the movement of the push plate 602, and the push plate 602 enters the discharge channel to complete the loading action of the ceramic substrate. Similarly, when the carrier plate 3 is away from the loading station, the travel switch issues a closing command to realize the power off of the electromagnet 605, and the push plate 602 will be reset.

[0029] like Figure 2 As shown, in some embodiments, a return spring 606 is connected between the mounting block 603 and the bracket 601 , and the purpose of the return spring 606 is to pull the push plate 602 to return to the initial position.

[0030] like Figure 2 As shown, in some embodiments, a pull rope 607 is installed on the mounting block 603, and the pull rope 607 passes through the reset spring 606 and the bracket 601. The end of the pull rope 607 is connected to a counterweight block 608, and the counterweight block 608 is a magnet. An iron block 2 609 is installed on the frame 1. In order to ensure the stability of the position of the push plate 602 after the push plate 602 is reset, the structure is further improved. Based on the counterweight block 608, a force can be generated to pull the push plate 602 away from the electromagnet 605, and when the counterweight block 608 moves to contact the iron block 2 609 to form a magnetic connection, the position of the push plate 602 can be locked.

[0031] like Figure 4 As shown, in some embodiments, the lever 7 is rotatably connected to the supporting plate 3 through a one-way bearing, and a gear 15 is connected to the rotating shaft of the lever 7 through a one-way bearing, and the two one-way bearings limit the directions in opposite directions. A rack 16 is arranged on the frame 1. Due to the cooperation of the two one-way bearings, when the supporting plate 3 moves from the detection station to the upper and lower loading and unloading station, the gear 15 cannot rotate relative to the rotating shaft under the action of the one-way bearing, but the gear 15 and the rotating shaft can rotate as a whole. At this time, the lever 7 rotates to complete unloading, and when the supporting plate 3 moves from the loading and unloading station to the detection station, the rotating shaft cannot rotate, but the gear 15 can rotate relative to the rotating shaft. At this time, the position of the lever 7 remains unchanged, and the lever 7 makes a complete circular motion each time it unloads.

[0032] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
