Description

Technical Field

[0001] The utility model relates to the technical field of ceramic capacitor production equipment, in particular to a quick-change suction cup mechanism for taking and placing ceramic capacitor blocks. Background Art

[0002] Ceramic capacitors are a general term for capacitors using ceramic materials as dielectric materials. Multilayer ceramic capacitors (MLCCs), also known as chip capacitors, multilayer capacitors, and stacked capacitors, are a type of ceramic capacitor. MLCCs are characterized by their small size, high capacitance, low loss at high frequencies, suitability for mass production, low price, and high stability.

[0003] The preparation of the internal electrodes of multilayer ceramic capacitors (MLCCs) uses the principle of screen printing. On the cast dielectric ceramic film, the internal electrodes are printed into internal electrode patterns of a certain shape and size, and the internal electrode structure is formed by the method of dislocation and lamination, that is, a block is obtained. After warm isostatic pressing (under a certain temperature and pressure), the bonding between the layers of the block is made tighter and tighter. The laminated blocks are then cut and glued, and the blocks are cut into capacitor chip green bodies of the designed size using cutting technology. The capacitor chip green body is debonded and sintered at high temperature to make the green body a porcelain body, and the ceramic dielectric and internal electrodes are sintered into a dense monolithic whole.

[0004] Typically, a vacuum suction cup device is used to hold the bar and then transport it to the gluing and cutting processes. When producing ceramic capacitors of different specifications, the thickness and surface area of ​​the bar vary, necessitating the use of different vacuum suction cup devices. Traditional vacuum suction cup devices use an integrally molded suction cup plate, which is difficult to remove individually. Bars are typically square, and there are four main types of bar types:

[0005] (1) When the produced block is thicker and the surface area of ​​the block is larger, such as Figure 1 As shown, a suction cup plate with a suction nozzle is used to suck the block for transportation, and the suction nozzle 55 is located on the outer surface of the suction cup plate 5; the first type of vacuum suction cup device is used here;

[0006] (2) When the produced block is thicker and the surface area of ​​the block is smaller, such as Figure 2 As shown, a suction cup plate with a suction nozzle is used to suck the block for transportation, and the suction nozzle 55 is located on the inner side of the surface of the suction cup plate 5. If the suction nozzle is on the outer side of the surface of the suction cup plate, it will easily exceed the edge of the block and thus fail to suck the block. Here, a second type of vacuum suction cup device is used;

[0007] (3) When the produced block is thin, such as one millimeter thick, and the surface area of ​​the block is large, if the block is sucked by the suction cup of the suction nozzle, it is easy to suck out concave and convex shapes on the surface of the block due to the strong suction force of a single suction nozzle, resulting in poor quality of the block, such as Figure 3 As shown, at this time, a suction cup plate with dense suction holes is used to suck the block for transportation, and the dense suction holes 56 are located on the outer surface of the suction cup plate 5; the third type of vacuum suction cup device is used here;

[0008] (4) When the produced blocks are thin and the surface area of ​​the blocks is small, such as Figure 4 As shown, a suction cup plate with dense suction holes is used to suck the block for transportation, and the dense suction holes 56 are located on the inner side of the surface of the suction cup plate 5; the fourth type of vacuum suction cup device is used here. A total of four types of vacuum suction cup devices are required

[0009] A total of four types of vacuum suction cup devices need to be prepared. When the production specifications of ceramic capacitor blocks change, the staff must replace the vacuum suction cup device of the ceramic capacitor production line in advance, select the vacuum suction cup device with the corresponding suction cup plate and manually re-install it to the ceramic capacitor production line. Such installation operation is cumbersome, time-consuming, and the replacement speed is slow. Utility Model Content

DETAILED DESCRIPTION

[0044] The embodiment of the present utility model provides a quick-change suction cup mechanism for picking up and placing ceramic capacitor blocks, which overcomes the shortcomings of the background technology that four vacuum suction cup devices need to be prepared, the installation operation of the vacuum suction cup is cumbersome and time-consuming, and the replacement speed is slow; it realizes that only two suction cup plates need to be prepared, the suction cup plates are detachable structures, and the inner and outer suction areas of the suction cup plates are selected by operating the pipeline switching valve, which is easy to operate, quick to replace, saves installation time, and improves production efficiency.

[0045] The overall idea of ​​the technical solution of the embodiment of the utility model is as follows:

[0046] (1) When the produced block is thicker and the surface area of ​​the block is larger, a suction cup plate with a suction nozzle is selected, and the suction cup plate is locked to the base plate by a buckle, and then the knob of the pipeline switching valve is operated to connect the air outlet of the pipeline switching valve with the first suction port, thereby generating negative pressure at the first vacuum pipe joint, and with the help of the first through hole, the first through hole and the first annular groove, the first suction nozzle located on the outer side of the lower surface of the suction cup plate generates suction, so that the block at this time is sucked, and the mounting base is connected to the moving device of the prior art to transport the block to the next process.

[0047] (2) When the produced bar block is thicker and the surface area of ​​the bar block is smaller, a suction cup plate with a suction nozzle is used, and then the knob of the pipeline switching valve is operated to make the air outlet of the pipeline switching valve communicate with the second suction port, thereby generating negative pressure at the second vacuum pipe joint, and with the help of the second through hole, the second through hole and the second annular groove, the second suction nozzle located on the inner side of the lower surface of the suction cup plate generates suction, thereby sucking the bar block at this time; because the first suction nozzle located on the outer side of the lower surface of the suction cup plate has no suction at this time, the first suction nozzle does not contact the bar block, thus avoiding the waste of suction force at the first suction nozzle.

[0048] (3) When the produced block is thin and the surface area of ​​the block is large, a suction cup plate with dense suction holes is used, and the suction cup plate is locked to the substrate by a buckle, and then the knob of the pipeline switching valve is operated to make the air outlet of the pipeline switching valve become connected to the first suction port, thereby generating negative pressure at the first vacuum pipe joint, and with the help of the first through hole, the first through hole and the first annular groove, the first annular dense suction holes located on the outer side of the lower surface of the suction cup plate generate suction, so that the block at this time is sucked.

[0049] (4) When the produced block is thin and the surface area of ​​the block is small, a suction cup plate with dense suction holes is used, and then the knob of the pipeline switching valve is operated to make the air outlet of the pipeline switching valve communicate with the second suction port, thereby generating negative pressure at the second vacuum pipe joint, and with the help of the second through hole, the second through hole and the second annular groove, the second annular dense suction holes located on the inner side of the lower surface of the suction cup plate generate suction, so that the block at this time is sucked. Since the first annular dense suction holes located on the outer side of the lower surface of the suction cup plate have no suction at this time, the first annular dense suction holes do not contact the block, avoiding waste of suction in the first annular dense suction holes.

[0050] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0051] See Figures 1 to 18 , a preferred embodiment of the present utility model.

[0052] A quick-change suction cup mechanism for picking up and placing ceramic capacitor blocks, comprising:

[0053] Mounting base 1, guide rod 2, base plate 3, intermediate plate 4, suction cup plate 5, buckle 6, first vacuum pipe joint 7, second vacuum pipe joint 8 and pipeline switching valve 9;

[0054] The mounting base 1 is connected to the upper surface of the substrate 3 via the guide rod 2. A first through hole 31 is formed on the outer side of the upper surface of the substrate 3, and a second through hole 32 is formed on the inner side of the upper surface of the substrate 3. The first vacuum pipe joint 7 is installed in the first through hole 31, and the second vacuum pipe joint 8 is installed in the second through hole 32.

[0055] The intermediate plate 4 is fixedly arranged on the lower surface of the base plate 3, and the upper surface of the suction cup plate 5 is tightly attached to the lower surface of the intermediate plate 4. The base plate 3 and the suction cup plate 5 are connected by the buckle 6. The lower surface of the intermediate plate 4 is provided with a first annular groove 41 and a second annular groove 42. The first annular groove 41 is outside the second annular groove 42. The first annular groove 41 has a first through hole 43, which is aligned with the first through hole 31. The second annular groove 42 has a second through hole 44, which is aligned with the second through hole 32.

[0056] The pipeline switching valve 9 is fixedly arranged on the substrate 3, the first air intake port 91 of the pipeline switching valve 9 is connected to the first vacuum pipe joint 7, and the second air intake port 92 of the pipeline switching valve 9 is connected to the second vacuum pipe joint 8;

[0057] The lower surface of the suction cup plate 5 has a first suction nozzle 51 and a second suction nozzle 52. The first suction nozzle 51 is in communication with the first annular groove 41, and the second suction nozzle 52 is in communication with the second annular groove 42. The first suction nozzles 51 and the second suction nozzles 52 are distributed in an annular pattern, and the first suction nozzles 51 surround the second suction nozzles 52.

[0058] Alternatively, the lower surface of the suction cup plate 5 has a first annular dense suction hole 53 and a second annular dense suction hole 54, the first annular dense suction hole 53 is communicated with the first annular groove 41, the second annular dense suction hole 54 is communicated with the second annular groove 42, and the first annular dense suction hole 53 surrounds the second annular dense suction hole 54.

[0059] The beneficial effect of the above technical solution is that the suction cup plate 5 is a detachable structure. The staff can separate and assemble the suction cup plate 5 from the base plate 3 by operating the pull buckle 6, so as to quickly replace the suction cup plate 5. The suction cup plate with a suction nozzle and the suction cup plate with annular dense suction holes both have an inner suction area and an outer suction area. The staff can select the corresponding suction area by operating the pipeline switching valve 9, which is convenient to operate and can be replaced quickly. Only two types of suction cup plates 5 need to be prepared, matched with a pipeline switching valve 9 and its corresponding pipeline structure, to quickly respond to the four types of block situations recorded in the background technology, save installation time, and improve production efficiency.

[0060] Mounting base 1 is connected to a conventional mobile device, and outlet 93 of pipeline switching valve 9 is connected to a conventional vacuum generator. Pull buckle 6, also known as a hasp, operates on the same principle as conventional hasps used in computer cases or wooden box accessories. The hasp allows the box lid to be securely fastened to the box, while also allowing for padlockable locking and convenient opening.

[0061] Two buckles 6 are provided on the left side of the substrate 3 and the suction cup plate 5, and two buckles 6 are provided on the right side of the substrate 3 and the suction cup plate 5. The beneficial effect of this technical solution is that the connection stability of the suction cup plate 5 and the substrate 3 is improved.

[0062] The mounting base 1 further includes a guide sleeve 21, a limit block 22, and a compression spring 23. The guide sleeve 21 is fixedly arranged on the upper surface of the mounting base 1, the guide rod 2 is slidably connected to the guide sleeve 21, the limit block 22 is fixedly connected to the upper end of the guide rod 2, the limit block 22 is located above the guide sleeve 21, the lower end of the guide rod 2 is fixedly connected to the base plate 3, and the compression spring 23 is sleeved on the guide rod 2 and located between the mounting base 1 and the base plate 3. The beneficial effect of this technical solution is that when the mounting base 1 moves downward and the lower surface of the suction cup plate 5 contacts the block 10, the suction cup plate 5 stops, and the mounting base 1 moves downward along the guide rod 2 at a reduced speed. At the same time, the compression spring 23 is in a compressed state, which plays a buffering role to avoid crushing the block 10. After the suction cup plate 5 sucks the block 10, the mounting base 1 moves upward, and the compression spring 23 is in a reset state. The suction cup plate 5 carries the block 10 to the next process.

[0063] The device further includes a heating tube 45 and a thermocouple 46. The substrate 3 is a heat-insulating substrate 3, and the intermediate plate 4 is a heating plate. Both the heating tube 45 and the thermocouple 46 are inserted into the heating plate. The beneficial effect of this technical solution is that the heating tube 45 generates heat, raising the temperature of the intermediate plate 4 and the suction cup plate 5 to a specified temperature. While the suction cup plate 5 is sucking the block 10, the block 10 is preheated in preparation for the subsequent high-temperature sintering process. The thermocouple 46 is used to detect the temperature of the intermediate plate 4. The thermocouple 46 is a commonly used temperature measuring element in temperature measuring instruments. It directly measures temperature and converts the temperature signal into a thermoelectromotive force signal, which is then converted into the temperature of the measured medium through an electrical instrument.

[0064] A first sealing gasket (not shown) is installed between the base plate 3 and the intermediate plate 4, and a second sealing gasket (not shown) is installed between the intermediate plate 4 and the suction cup plate 5. This technical solution has the beneficial effect of preventing vacuum leakage at the connection between the base plate 3 and the intermediate plate 4, and also preventing vacuum leakage at the connection between the intermediate plate 4 and the suction cup plate 5.

[0065] Working mode of this utility model:

[0066] (1) Combination Figure 14 When the produced block is thicker and the surface area of ​​the block is larger, a suction cup plate 5 with a suction nozzle is selected. The staff quickly installs this suction cup plate 5 through the pull buckle 6, and then operates the knob of the pipeline switching valve 9 to connect the first suction nozzle 51 to the vacuum generating device to generate suction and suck the block 10 at this time.

[0067] (2) Combination Figure 15 When the produced block is thicker and the surface area of ​​the block is smaller, select the suction cup plate 5 with a suction nozzle, and then operate the knob of the pipeline switching valve 9 to connect the second suction nozzle 52 to the vacuum generating device to generate suction and suck the block 10 at this time.

[0068] (3) Combination Figure 17 When the produced bar blocks are thin and the surface area of ​​the bar blocks is large, a suction cup plate 5 with dense suction holes is selected. The suction force of the dense suction holes is evenly distributed to avoid sucking out concave and convex shapes on the surface of the bar blocks; the staff quickly installs this suction cup plate 5 through the pull buckle 6, and then operates the knob of the pipeline switching valve 9 to connect the first annular dense suction hole 53 to the vacuum generating device to generate suction and suck the bar blocks 10 at this time.

[0069] (4) Combination Figure 18 When the produced block is thin and the surface area of ​​the block is small, select the suction cup plate 5 with dense suction holes, and then operate the knob of the pipeline switching valve 9 to connect the second annular dense suction holes 54 to the vacuum generating device to generate suction and suck the block 10 at this time.

[0070] By adopting the quick-change suction cup mechanism for taking and placing ceramic capacitor blocks of the present invention, when the production specifications of the ceramic capacitor blocks change, the staff can quickly replace the suction cup plate and operate the pipeline switching valve to adapt to the specifications of the blocks to be transported.
