Abstract
Description
Technical Field
[0001] This invention relates to a feeding and arranging device, specifically a feeding and arranging device for multilayer ceramic chip capacitors, belonging to the field of manufacturing technology for multilayer ceramic chip capacitors. Background Technology
[0002] In the production of multilayer ceramic chip capacitors (MLCCs), end paste needs to be coated onto both ends of the exposed internal electrodes of the chip to connect the internal electrodes on the same side and form the external electrodes, a process called end sealing. Afterward, the ends need to be heated at high temperature in a firing furnace to solidify them and form a good connection with the ceramic body and internal electrodes; this process is called firing. Before firing, the sealed MLCC product is laid on a nickel mesh, which serves as a fixture. Then, the nickel mesh filled with the MLCC product is placed on the mesh chain of the firing furnace and sent into the furnace for firing.
[0003] In existing technologies, a fixed quantity of MLCC products is manually blown onto a nickel mesh to form a uniform layer. Since the equipment operates continuously during MLCC production, this manual blowing method requires workers to keep pace with the equipment, resulting in prolonged, high-intensity continuous labor. This inevitably affects the quality of the MLCC products, leading to increased bonding defects, insufficient coverage, uneven product arrangement, and unstable product quality.
[0004] Based on the above analysis, the research and development of a feeding and arranging device for multilayer ceramic capacitor (MLCC) products to replace the manual air blowing method and achieve uniform array arrangement of MLCC products on nickel grid is of great significance to this field. Summary of the Invention
[0005] Based on the above background, the purpose of this invention is to provide a feeding and arranging device for multilayer ceramic capacitor (MLCC) products, which replaces manual air blowing with an automated method to uniformly arrange MLCC products on a nickel grid, thereby improving the quality stability of MLCC products and reducing defective products with burnt ends.
[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solution:
[0007] A feeding and arranging device for multilayer ceramic chip capacitors includes:
[0008] A vibratory material spreading module includes a base, a first driving member, a second driving member, a lower screen assembly, and an upper screen assembly. The first driving member is mounted on the base, and the lower screen assembly is hinged to the base. The second driving member is mounted on the lower screen assembly, and the upper screen assembly is located above the lower screen assembly and slidably connected to it. The output end of the first driving member is connected to the end of the lower screen assembly, allowing the lower screen assembly to reciprocate relative to the base under the drive of the first driving member. The output end of the second driving member is connected to the upper screen assembly, allowing the upper screen assembly to reciprocate linearly relative to the lower screen assembly under the drive of the second driving member. The linear reciprocating sliding direction of the upper screen assembly is parallel to the hinge axis between the lower screen assembly and the base. The upper screen assembly is provided with a screen mesh having a plurality of arrayed screen holes.
[0009] The conveying module is used to transport the nickel mesh displacement to the position below the vibrating laying module;
[0010] The lifting module is used to lift the nickel mesh conveyed by the conveying module to the bottom of the screen and then lower it back to the conveying module.
[0011] The upper screen assembly carries the multilayer ceramic chip capacitor products, and the conveying module transports the nickel mesh. When the empty nickel mesh is moved to the position below the vibrating material laying module, the top of the lifting module lifts the empty nickel mesh on the conveying module to a position adjacent to the bottom of the screen. Under the driving action of the first and second driving components, the upper screen assembly exhibits a combination of left-right vibration and back-and-forth swinging motion, causing the multilayer ceramic chip capacitor products to fall into the array of screen holes of the screen, and then be evenly arranged on the empty nickel mesh through the array of screen holes. The top of the lifting module falls down, causing the nickel mesh with multilayer ceramic chip capacitor products to descend onto the conveying module, which continues to transport it forward to the subsequent firing process.
[0012] Preferably, the conveying module is located below the vibrating material spreading module. The conveying module includes multiple conveyor belt assemblies with conveying working surfaces, which are arranged side by side at intervals. The lifting module is located below the vibrating material spreading module, with its lower part below the conveying module. The top of the lifting module is configured to pass through the gap between adjacent conveyor belt assemblies. The top of the lifting module has a first position and a second position relative to the bottom of the vibrating material spreading module. When in the first position, the top of the lifting module is located below the conveying working surface of the conveyor belt assembly and away from the bottom of the screen. When in the second position, the top of the lifting module is located above the conveying working surface of the conveyor belt assembly and adjacent to the bottom of the screen.
[0013] Preferably, the lower screen assembly includes a lower screen frame, a first guide rail, and a first slider. The lower screen frame is a frame structure with a through-center. Two opposite sides of the lower screen frame are provided with rotary mounting holes, and the two rotary mounting holes are coaxially arranged.

The first slider is disposed on the first guide rail, and the first slider can slide relative to the first guide rail along the extension direction of the first guide rail.
[0014] Preferably, the upper screen assembly includes an upper screen frame, a screen frame, and a baffle. Both the upper screen frame and the screen frame are frame structures with a through-center.

[0016] Preferably, the bottom of the outer edge of the top of the lifting module is provided with an inclined surface. The straight-line distance between the inclined surface and the top surface of the lifting module gradually decreases from the center of the top of the lifting module towards the outer edge. The top of the lifting module also has a third position relative to the bottom of the vibratory laying module, which is between the first and second positions. When the top of the lifting module is in the second position, the top of the guide wheel abuts against the inclined surface, and the inclined surface is pressed tightly against the lifting module by displacement along the inclined surface from the outer edge of the top of the lifting module towards the center of the top of the lifting module. The top of the lifting module then shifts from the second position to the third position. The lowering of the top of the lifting module to the third position provides space for the vibration movement of the vibratory laying module, especially its back-and-forth swinging movement, avoiding interference and serving a positioning avoidance function.
[0017] Preferably, the first driving component includes a first motor, a reducer, a bearing housing, and a rotating shaft. There are two bases.

[0020] Preferably, the conveying module further includes a conveying support, a second motor, and a transmission belt component. The second motor is fixedly connected to the conveying support, and the output end of the second motor is connected to the conveying belt assembly through the transmission belt component. The conveying belt assemblies are arranged side-by-side and spaced apart on the conveying support. Each conveying belt assembly includes a driving pulley, a driven pulley, and a belt. The top portion of the belt located between the driving pulley and the driven pulley is configured as a conveying working surface. The number of conveying belt assemblies is at least four. At least two conveying belt assemblies have a first gap between their driving pulleys and driven pulleys, and at least two conveying belt assemblies have a second gap between their driving pulleys and driven pulleys.

It should be understood that the implementation of the present invention is not limited to the following embodiments, and any modifications and / or alterations made to the present invention will fall within the protection scope of the present invention.
[0037] In this invention, unless otherwise specified, all parts and percentages are by weight, and the equipment and raw materials used are commercially available or commonly used in the art. Unless otherwise specified, the methods in the following embodiments are conventional methods in the art. Unless otherwise specified, the components or equipment in the following embodiments are general standard parts or components known to those skilled in the art, and their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.
[0038] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. In this detailed description, numerous specific details are set forth to facilitate explanation and provide a thorough understanding of the embodiments of the present invention. However, one or more embodiments may be practiced by those skilled in the art without these specific details.
[0039] refer to Figure 1-3This invention discloses a feeding and arranging device for multilayer ceramic chip capacitors, comprising a vibratory feeding module 1, a conveying module 2, and a lifting module 3. The conveying module 2 is located below the vibratory feeding module 1, and the lifting module 3 is located below the vibratory feeding module 1, with the lower part of the lifting module 3 located below the conveying module 2.
[0040] refer to Figure 4-5 The vibratory material spreading module 1 includes a base 110, a first drive member 120, a second drive member 130, a lower screen assembly 140, and an upper screen assembly 150. The first drive member 120 is disposed on the base 110, the lower screen assembly 140 is hinged to the base 110, the second drive member 130 is disposed on the lower screen assembly 140, and the upper screen assembly 150 is located above the lower screen assembly 140 and slidably connected to it. The output end of the first drive member 120 is connected to the end of the lower screen assembly 140, and the lower screen assembly 140 can be driven by the first drive member 120 to reciprocate relative to the base 110. The output end of the second drive member 130 is connected to the upper screen assembly 150, and the upper screen assembly 150 can be driven by the second drive member 130 to linearly reciprocate relative to the lower screen assembly 140. The linear reciprocating sliding direction of the upper screen assembly 150 is parallel to the hinge axis between the lower screen assembly 140 and the base 110. The upper sieve assembly 150 carries the multilayer ceramic chip capacitor product. The upper sieve assembly 150 is provided with a screen 1510, which has a plurality of arrayed screen holes 1511. Under the driving action of the first driving member 120 and the second driving member 130, the upper sieve assembly 150 can exhibit a combination of left-right vibration and back-and-forth swinging motion, so that the multilayer ceramic chip capacitor product located in the upper sieve assembly 150 falls into the arrayed screen holes 1511 of the screen 1510, thereby allowing the multilayer ceramic chip capacitor product to pass through the arrayed screen holes 1511 and be evenly arranged on the empty nickel grid.
[0041] Refer again Figure 1 and Figure 3 The conveying module 2 is used to transfer the nickel mesh displacement to the position below the vibrating laying module 1. The conveying module 2 includes multiple conveyor belt assemblies 210 with conveying working surfaces 214, and the conveyor belt assemblies 210 are arranged side by side at intervals.
[0042] The top of the lifting module 3 is configured to pass through the gap between adjacent conveyor belt assemblies 210. The top of the lifting module 3 has a first position and a second position relative to the bottom of the vibrating spreading module 1. When in the first position, the top of the lifting module 3 is below the conveying working surface 214 of the conveyor belt assembly 210 and away from the bottom of the screen 1510; when in the second position, the top of the lifting module 3 is above the conveying working surface 214 of the conveyor belt assembly 210 and adjacent to the bottom of the screen 1510.
[0043] When the empty nickel mesh conveyed by the conveying module 2 is moved to a position below the vibrating material laying module 1, the top of the lifting module 3 rises from the first position to the second position, lifting the empty nickel mesh on the conveying working surface 214 to a position adjacent to the bottom of the screen 1510. In conjunction with the movement of the upper screen assembly 150, the chip multilayer ceramic capacitor products in the upper screen assembly 150 are evenly arranged on the empty nickel mesh. After that, the top of the lifting module 3 falls from the second position to the first position, causing the nickel mesh with the chip multilayer ceramic capacitor products to fall onto the conveying working surface 214, and then the conveying module 2 continues to convey it forward to the subsequent firing process.
[0044] The structure of the vibratory material laying module 1 is described in detail below.
[0045] refer to Figure 6 The lower screen assembly 140 includes a lower screen frame 141, a first guide rail 142, and a first slider 143. The lower screen frame 141 is a frame structure with a through-center. Two opposite sides of the lower screen frame 141 are provided with rotary mounting holes 144, and the two rotary mounting holes 144 are coaxially arranged. The first guide rail 142 is fixed to the top surface of the lower screen frame 141, and the extension direction of the first guide rail 142 is parallel to the extension direction of the rotary mounting holes 144. The first slider 143 is disposed on the first guide rail 142, and the first slider 143 can slide relative to the first guide rail 142 along the extension direction of the first guide rail 142.
[0046] The upper screen assembly 150 includes an upper screen frame 151, a screen frame 152, and a baffle. Both the upper screen frame 151 and the screen frame 152 are frame-shaped structures with a through-center. The upper screen frame 151 is located below the screen frame 152, and the bottom of the upper screen frame 151 is fixedly connected to the first slider 143, so that the upper screen frame 151 can slide linearly back and forth relative to the lower screen frame 141 along the first guide rail 142. The baffle is located on the top of the screen frame 152 and covers part of the top opening of the screen frame 152. The screen mesh 1510 is located between the bottom of the screen frame 152 and the top of the upper screen frame 151. Specifically, there are two baffles, namely a large baffle 153 and a small baffle 154. The feeding end of the screen frame 152 is fixedly connected to the small baffle, and the other end of the screen frame 152 is fixedly connected to the large baffle 153. The gap between the large baffle 153 and the small baffle forms the feeding port of the screen frame 152. The large baffle 153 and the small baffle can block debris and prevent debris from falling into the chip multilayer ceramic capacitor product of the screen frame 152.
[0047] refer to Figure 7 and combined Figure 9The upper screen assembly 150 also includes a clamping component for attaching the nickel mesh located at the top of the lifting module 3 to the bottom of the screen 1510. The clamping component is located at the bottom of the upper screen frame 151 and includes a cylinder 155, a second guide rail 156, a second slider 157, a guide wheel seat 158, and a guide wheel 159. The cylinder 155 and the second guide rail 156 are both fixedly connected to the bottom of the upper screen frame 151. The output end of the cylinder 155 is connected to the guide wheel seat 158 through a floating joint. The guide wheel seat 158 is fixedly connected to the second slider 157. The second slider 157 is located on the second guide rail 156 and can slide relative to the second guide rail 156 along the extension direction of the second guide rail 156. The guide wheel 159 is located on the side of the guide wheel seat 158.
[0048] The top of the lifting module 3 has an inclined surface 381 at its bottom outer edge. The straight-line distance between the inclined surface 381 and the top surface of the lifting module 3 gradually decreases from the center of the top towards the outer edge. The top of the lifting module 3 also has a third position relative to the bottom of the vibrating material spreading module 1, which is between the first and second positions. When the top of the lifting module 3 is in the second position, the top of the guide wheel 159 abuts against the inclined surface 381, and the inclined surface 381 is pressed tightly against the lifting module 3 from its outer edge towards the center. This causes the top of the lifting module 3 to shift from the second position to the third position.
[0049] During operation, the lifting module 3 moves from the first position to the second position, the cylinder 155 actuates, and the piston rod, acting as the output end of the cylinder 155, pushes out, causing the floating joint to drive the guide wheel seat 158 to slide along the second guide rail 156, moving towards the top of the lifting module 3. The top of the guide wheel 159 abuts against the inclined surface 381 on the nickel mesh support plate 380, supporting the nickel mesh support plate 380 located at the top of the lifting module 3 (described later). The top of the lifting module 3 moves down, and since the nickel mesh support plate 380 is supported by the guide wheel 159, the top of the lifting module 3 separates from the nickel mesh support plate 380, and the lifting module 3 descends from the second position to the third position, providing a special vibration for the vibratory laying module. Its back-and-forth swinging motion provides space, avoids interference, and plays a role in positioning; the cylinder 155 continues to move, causing the guide wheel 159 to move from the outer edge of the top of the lifting module 3 towards the center of the top of the lifting module 3 along the inclined surface 381. As the guide wheel 159 moves along the inclined surface 381, the nickel mesh support plate 380 moves up a small distance, eliminating the gap between the screen 1510 and the nickel mesh on the nickel mesh support plate 380, so that the nickel mesh fits tightly against the screen 1510. At this time, the relative position of the nickel mesh and the screen 1510 is fixed, and the nickel mesh can move with the screen 1510, ensuring that the chip multilayer ceramic capacitor product falls evenly and stably onto the nickel mesh through the screen holes 1511 of the screen 1510. It should be noted that in order for the guide wheel 159 to smoothly support the nickel mesh support plate 380 by abutting the inclined surface 381, the clamping parts are arranged in pairs, that is, the two clamping parts are arranged opposite to each other on both sides of the bottom of the screen 1510, clamping the nickel mesh support plate 380 from opposite directions.
[0050] Refer again Figure 5 The first driving component 120 includes a first motor 121, a reducer 122, a bearing seat 123, and a rotating shaft 124. There are two bases 110. The first motor 121 and the reducer 122 are fixedly connected to one base 110. The output end of the first motor 121 is connected to one end of the lower screen assembly 140 through the reducer 122. The bearing seat 123 is fixedly connected to the other base 110. The rotating shaft 124 is sleeved in the bearing seat 123. The rotating shaft 124 is hinged to the other base 110 through the bearing seat 123. One end of the rotating shaft 124 is connected to the other end of the lower screen assembly 140 and is arranged opposite to the reducer 122. The rotating shaft 124 and the output end of the reducer 122 are coaxially arranged. The first motor 121 drives the lower screen assembly 140 to rotate clockwise or counterclockwise relative to the base 110 by a set angle through the reducer 122, forming a swing motion of the lower screen assembly 140. This causes the multilayer ceramic chip capacitor product in the upper screen assembly 150 located on the lower screen assembly 140 to move relative to the upper screen assembly 150, thereby falling into the screen holes 1511 of the screen 1510.
[0051] The base 110, connected to the bearing housing 123, is also equipped with a sensor 111 and a sensing plate 112. The sensing plate 112 is located at the end of the rotating shaft 124 away from the end of the lower screen assembly 140, and the sensor 111 is located below the sensing plate 112 and is fixedly connected to the base 110. The sensor 111 monitors the movement of the sensing plate 112 to obtain the rotation angle of the lower screen assembly 140, facilitating feedback control. Each base 110 has a vibration damping component at its bottom. This vibration damping component is existing technology and is used to reduce the vibration transmitted by the upper screen assembly 150 and the lower screen assembly 140 to the base 110.
[0052] The second driving component 130 includes a pneumatic tendon stretching actuator 131 and a transmission component 132. The pneumatic tendon stretching actuator 131 is disposed at the bottom of the lower screen frame 141. The output end of the pneumatic tendon stretching actuator 131 is fixedly connected to one end of the transmission component 132, and the other end of the transmission component 132 is fixedly connected to the bottom of the upper screen frame 151. The driving direction of the pneumatic tendon stretching actuator 131 is parallel to the extension direction of the first guide rail 142. To improve driving efficiency and driving effect, two pneumatic tendon stretching actuators 131 are provided in this embodiment and arranged opposite to each other. Of course, the number can be adjusted according to the actual application scenario.
[0053] The structure of the conveying module 2 is described in detail below.
[0054] refer to Figure 8 The conveying module 2 includes a conveying support 220, a second motor 230, a transmission belt assembly 240, and seven conveyor belt assemblies 210. The second motor 230 is fixedly connected to the conveying support 220, and the output end of the second motor 230 is connected to the conveyor belt assembly 210 through the transmission belt assembly 240. The conveyor belt assemblies 210 are arranged side by side at intervals on the conveying support 220. Each conveyor belt assembly 210 includes a driving pulley 211, a driven pulley 212, and a belt 213. The top portion of the belt 213 located between the driving pulley 211 and the driven pulley 212 is configured as a conveying working surface 214.
[0055] Three conveyor belt assemblies 210 have a relatively large first gap between the driving pulley 211 and the driven pulley 212, constituting a long conveyor belt assembly 210. Four conveyor belt assemblies 210 have a relatively small second gap between the driving pulley 211 and the driven pulley 212, constituting a short conveyor belt assembly 210. Specifically, the value of the first gap is greater than twice the value of the second gap. Of course, the number of conveyor belt assemblies 210 can be adjusted according to the needs of the actual application scenario, as long as the number of conveyor belt assemblies 210 is at least four, of which at least two are long conveyor belt assemblies 210 and at least two are short conveyor belt assemblies 210.
[0056] Three long conveyor belt assemblies 210 carry and transport the nickel mesh, and a short conveyor belt assembly 210 located between two adjacent long conveyor belt assemblies supports the middle of the nickel mesh to ensure that the nickel mesh does not deform due to uneven force. The distance between adjacent short conveyor belt assemblies 210 and long conveyor belt assemblies 210 is set to allow the top of the lifting module 3 (described later) to pass smoothly without interference.
[0057] The structure of the lifting module 3 is described in detail below.
[0058] refer to Figure 9-10 The lifting module 3 includes a lifting frame 310, a third motor 320, a lead screw nut 330, a ball screw 340, a lifting base plate 350, a guide shaft 360, a lifting support plate 370, and a nickel mesh support plate 380. The third motor 320 is fixedly connected to the lifting frame 310. The output end of the third motor 320 is connected to one end of the ball screw 340, which is fitted inside the lead screw nut 330. The lead screw nut 330 is fixedly connected to the lifting base plate 350, and the lifting base plate 350 is fixedly connected to the lifting support plate 370 via the guide shaft 360. The nickel mesh support plate 380 is positioned above the lifting support plate 370, with an inclined surface 381 located at the bottom edge of the nickel mesh support plate 380.
[0059] Specifically, the nickel mesh support plate 380 and the top of the lifting frame 310 are detachably connected. When the lifting support plate 370 is not in the lifting state, the nickel mesh support plate 380 is placed on the top of the four pins on the top of the lifting frame 310. When the lifting support plate 370 is in the lifting state, it supports the nickel mesh support plate 380, causing the nickel mesh support plate 380 to move away from the top of the lifting frame 310 and upwards, moving towards the bottom of the screen 1510. Since the nickel mesh support plate 380 and the lifting frame 310 are not fixedly connected, their relative positions are defined by the following: the nickel mesh support plate 380 has a positioning hole 382 at its bottom, and the lifting support plate 370 has a positioning pin 371 at its top, with the positioning pin 371 matching the positioning hole 382. Of course, the positions of the positioning hole 382 and the positioning pin 371 can be interchanged, that is, the positioning pin 371 is set at the bottom of the nickel mesh support plate 380, while the positioning hole 382 is set at the top of the lifting support plate 370.
[0060] The third motor 320 drives the ball screw 340 to rotate, and the screw nut 330 moves up and down linearly relative to the ball screw 340, causing the lifting base plate 350 to move up and down linearly relative to the lifting frame 310. Since the lifting base plate 350 is fixedly connected to the lifting support plate 370, the movement of the lifting base plate 350 is transmitted to the lifting support plate 370, causing the lifting support plate 370 to lift the nickel mesh support plate 380 or move down to move the nickel mesh support plate 380 down.
[0061] This multilayer ceramic capacitor (MLCC) product feeding and arrangement device uses the coordinated movement of the vibration feeding module 1, the conveying module 2, and the lifting module 3 to vibrate and evenly drop the multilayer ceramic capacitor products through the screen holes 1511 of the screen 1510 onto the nickel mesh and transport them to the subsequent process. This enables continuous and stable feeding to the subsequent firing furnace. The device reduces human error and human factors, improves the quality stability of MLCC products, and reduces defective products from firing.
