Technical Field

[0001] The present invention relates to the technical field of capacitor production, in particular to an automatic core arranging machine for capacitor production. Background Art

[0002] The automatic core arranging machine automatically arranges the cores neatly on the hot pressing plate to prepare for hot pressing and shaping. After searching, the Chinese invention patent with application number CN202211580016.5 discloses an efficient multi-row chip automatic tube loading device, which shortens the loading time of the material tube. At the same time, multiple material tubes are loaded with chips at the same time, which improves the efficiency of chip loading.

[0003] The parts of the above-mentioned device need to start and stop when moving to the work station, which can easily cause the core to shake during the startup process. This is mainly because the acceleration of the support structure at the bottom of the core changes greatly when starting and stopping. Dragging the bottom of the core to move can easily cause the core to slip or shake, reducing the neatness of the arranged cores. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the present invention provides an automatic core arranging machine for capacitor production, which solves the technical problem that the existing core arranging machine easily causes the core to shake during the start and stop of transportation, thereby reducing the neatness of the arranged cores.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: An automatic core arranging machine for capacitor production comprises a core arranging machine body, a belt conveying mechanism is installed on the top of the core arranging machine body, and a start-stop buffer assembly is installed on the core arranging machine body; The start-stop buffer assembly includes a hot press plate, a support frame, a spring, and a contact block assembly. The hot press plate is driven by a belt conveyor mechanism. The support frame is installed on the top of the core arrangement machine body. The contact block assembly is installed in the support frame and is slidably connected to the hot press plate. The spring is installed between the contact block assembly and the support frame.

[0006] Furthermore, the contact block assembly includes a slider slidably connected to the support frame, a cavity is provided inside the slider, an opening connected to the cavity is provided on the top of the slider, an exhaust pipe connected to the cavity is provided on one side of the slider, and a plurality of air holes corresponding to the openings are provided on the top of the hot pressing plate.

[0007] Furthermore, a longitudinal groove is provided on the top of the contact block assembly, a lifting block is slidably connected inside the longitudinal groove, and a rubber block is fixedly connected to the top of the lifting block.

[0008] Furthermore, a long slot communicating with the longitudinal slot is provided on one side of the contact block assembly, an extrusion plate is slidably connected to the inner wall of the long slot, and a bolt with one end movably extending into the interior of the long slot is provided on one side of the contact block assembly.

[0009] Further, one side of the contact block assembly is fixedly connected with an extension plate, a projection of the extension plate on a horizontal plane extends to the outside of a projection of the hot pressing plate on the horizontal plane, and the extension plate is fixedly connected with a limiting plate on the side away from the support frame.

[0010] Further, the limiting plate comprises straight plate segments and arc plate segments, and the distance between the two straight plate segments is the same as the width of the hot pressing plate.

[0011] Further, the top of the core arranging machine body is fixedly connected with an air cylinder, and the top of the air cylinder is fixedly connected with a feeding frame.

[0012] By the above technical solution, the application provides an automatic core arranging machine for capacitor production, which has at least the following beneficial effects: 1. The start-stop buffer assembly can slow down the acceleration of the hot pressing plate when it is driven to start moving by the belt conveying mechanism, so that the acceleration of the hot pressing plate when it is driven is reduced relative to the acceleration of the belt conveying mechanism, the acceleration of the hot pressing plate and the cores arranged above it is reduced, and the possibility of the cores shaking when being conveyed and started is reduced, thereby maintaining the neatness of the arranged cores.

[0013] 2. The limiting plate can guide the position of the hot pressing plate on the belt conveying mechanism, so that the hot pressing plate can always be in the middle of the belt conveying mechanism when it moves under the influence of the belt conveying mechanism and the contact block assembly, and the cores will not fall off when being placed on the hot pressing plate due to the movement of the hot pressing plate.

[0014] 3. The air extraction pipeline can use negative pressure to improve the firmness of the connection between the cores and the hot pressing plate, thereby reducing the possibility of the cores above the hot pressing plate shaking when the hot pressing plate moves.

[0015] 4. The lifting block and the rubber block can adjust the resistance of the sliding block when the hot pressing plate is driven by the belt conveying mechanism, thereby changing the moving speed of the hot pressing plate when the start speed of the belt conveying mechanism is fixed, so that the cores above the hot pressing plate will not shake when the hot pressing plate moves.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Example 1 In order to reduce the possibility of the discharged core shaking during the start and stop of the conveying process, and reduce the acceleration of the core when it is driven, please refer to Figures 1-4 This embodiment proposes an automatic core arranging machine for capacitor production, including a core arranging machine body 1, a belt conveyor mechanism 2 is installed on the top of the core arranging machine body 1, a start-stop buffer assembly 3 is installed on the core arranging machine body 1, and the start-stop buffer assembly 3 includes a hot press plate 31, a support frame 32, a spring 33, and a contact block assembly 34. The hot press plate 31 is driven by the belt conveyor mechanism 2, the support frame 32 is installed on the top of the core arranging machine body 1, the contact block assembly 34 is installed in the support frame 32 and is slidably connected to the hot press plate 31, and the spring 33 is installed between the contact block assembly 34 and the support frame 32.

[0020] When in use, the belt conveyor mechanism 2 drives the hot pressing plate 31 to move. When the hot pressing plate 31 moves to the position for placing the cores, the belt conveyor mechanism 2 stops moving and arranges the cores in a row on the hot pressing plate 31. Then, the belt conveyor mechanism 2 drives the cores forward for a distance and stops moving again, and continues to arrange the cores in a row on the hot pressing plate 31. The above process is repeated until the hot pressing plate 31 is fully filled with cores. The belt conveyor mechanism 2 drives the hot pressing plate 31 to continue moving forward to the next processing station. In the process of the belt conveyor mechanism 2 driving the hot pressing plate 31 from stopping to moving, the start-stop buffer assembly 3 reduces the possibility of the cores arranged on the hot pressing plate 31 shaking. The specific process is as follows: When the belt conveyor mechanism 2 drives the hot press plate 31 to move, the hot press plate 31 overcomes the friction of the contact block assembly 34 on its bottom. On the one hand, the hot press plate 31 drags the contact block assembly 34 to move, causing the spring 33 to deform, and at the same time slides relative to the contact block assembly 34, sliding off the contact block assembly 34. On the other hand, the friction between the contact block assembly 34 and the hot press plate 31 prevents the hot press plate 31 from accelerating. The contact block assembly 34 applies an external force to the hot press plate 31, causing the hot press plate 31 to move relative to the belt conveyor mechanism 2, so that the moving speed of the hot press plate 31 is less than the moving speed of the belt conveyor mechanism 2. Then, the hot press plate 31 continues to be moved by the belt conveyor mechanism 2 to the position where the next row of cores is placed. This can slow down the acceleration of the hot press plate 31 when it starts to move driven by the belt conveyor mechanism 2, so that the acceleration of the hot press plate 31 when it is driven is reduced relative to the acceleration of the belt conveyor mechanism 2, thereby reducing the acceleration of the hot press plate 31 and the cores arranged above it, thereby reducing the possibility of the cores shaking when being transported and started, and maintaining the neatness of the arranged cores.

[0021] The automatic core arranging process of the core arranging machine body 1 is as follows: the core is loaded through the vibrating plate and conveyed to the hot pressing plate via the belt. At the same time, the equipment uses a vacuum suction cup to absorb the hot pressing plate and sends it to the bottom of the belt. When the cores are filled in a row, the whole row of cores is pushed out, and the hot pressing plate moves down one row of stations. The cores continue to be discharged until the whole plate is full, and then the belt conveys the hot pressing plate to the stacking area.

[0022] In order to adjust the position of the hot pressing plate 31 placed on the belt conveyor 2, which is not in the correct position, refer to Figure 4 An extension plate 8 is fixedly connected to one side of the contact block assembly 34, and the projection of the extension plate 8 on the horizontal plane extends to the outside of the projection of the hot pressing plate 31 on the horizontal plane. The side of the extension plate 8 away from the support frame 32 is fixedly connected to a limiting plate 9, and the limiting plate 9 includes a straight plate section 91 and an arc plate section 92. The distance between the two straight plate sections 91 is the same as the width of the hot pressing plate 31.

[0023] When in use, the two limit plates 9 are respectively on both sides of the hot pressing plate 31 on the belt conveyor mechanism 2. When the hot pressing plate 31 is blocked by the contact block assembly 34 and swings to both sides, it will be blocked by the straight plate segment 91, so that the hot pressing plate 31 is always in the center of the belt conveyor mechanism 2. Before the hot pressing plate 31 enters between the limit plates 9, it moves to both sides. When the hot pressing plate 31 is driven by the belt conveyor mechanism 2 and gradually approaches the limit plate 9, the hot pressing plate 31 first contacts with the arc plate segment 92 on one side, and then is blocked by the arc plate segment 92. After being blocked, it moves along the arc plate segment 92 toward the center position of the belt conveyor mechanism 2 until the hot pressing plate 31 moves between the two straight plate segments 91. At this time, the hot pressing plate 31 moves to the center of the belt conveyor mechanism 2, which can guide the position of the hot pressing plate 31 on the belt conveyor mechanism 2, so that the hot pressing plate 31 can always be in the center position of the belt conveyor mechanism 2 when moving under the influence of the belt conveyor mechanism 2 and the contact block assembly 34. When the core is placed on the hot pressing plate 31, the core will not fall due to the movement of the hot pressing plate 31.

[0024] In order to place the core on the hot press plate 31, refer to Figure 1 The top of the core arranging machine body 1 is fixedly connected to a cylinder 10, and the top of the cylinder 10 is fixedly connected to a loading frame 11. When in use, the loading frame 11 is located in one of the rows on the hot pressing plate 31. The vibrating plate on the core arranging machine body 1 is responsible for conveying the cores, and the cylinder 10 is responsible for sending the loading frame 11 to the core placement position. After the cores on the loading frame 11 are full, they are automatically sent to the top material position to lift the core plate and then proceed to the next round of core arranging.

[0025] Example 2 In order to improve the firmness of the connection between the core and the hot pressing plate 31, thereby reducing the possibility of the core above the hot pressing plate 31 shaking when the hot pressing plate 31 moves, refer to Figure 1-Figure 5 On the basis of the first embodiment, the contact block assembly 34 includes a slider 341 slidably connected to the support frame 32, a cavity is provided inside the slider 341, an opening 342 communicating with the cavity is provided on the top of the slider 341, an exhaust pipe 343 communicating with the cavity is provided on one side of the slider 341, and a plurality of air holes corresponding to the opening 342 are provided on the top of the hot pressing plate 31.

[0026] When in use, the exhaust pipe 343 is connected to the pipeline system to continuously extract the air in the cavity of the slider 341, so that negative pressure is formed inside the slider 341, and then the air above the hot pressing plate 31 is extracted through the air vents. When a core is placed above the air vents, the core will be adsorbed on the hot pressing plate 31 by the negative pressure inside the slider 341. The negative pressure can be used to improve the firmness of the connection between the core and the hot pressing plate 31, thereby reducing the possibility of the core above the hot pressing plate 31 shaking when the hot pressing plate 31 moves.

[0027] In order to adjust the blocking effect of the contact block assembly 34 on the moving hot plate 31, and thus adjust the degree to which the hot plate 31 driven by the belt conveyor mechanism 2 is decelerated by the contact block assembly 34, refer to Figure 5 A longitudinal groove is provided on the top of the contact block assembly 34, and a lifting block 4 is slidably connected inside the longitudinal groove. A rubber block 5 is fixedly connected to the top of the lifting block 4. A long groove connected to the longitudinal groove is provided on one side of the contact block assembly 34, and an extrusion plate 6 is slidably connected to the inner wall of the long groove. A bolt 7 is provided on one side of the contact block assembly 34, one end of which is movably extended into the interior of the long groove.

[0028] When in use, the lifting block 4 is slid up and down along the longitudinal groove to adjust the proportion of the rubber block 5 moving above the slider 341. When the volume of the rubber block 5 moving above the slider 341 is larger, the area of ​​contact between the rubber block 5 and the hot pressing plate 31 after being squeezed by the hot pressing plate 31 passing through is larger, so the friction between the rubber block 5 and the hot pressing plate 31 is greater, resulting in greater resistance to the hot pressing plate 31. Then, the bolt 7 is turned, and the bolt 7 pushes the extrusion plate 6 gradually closer to the lifting block 4, squeezing the lifting block 4 on the slider 341 and fixing it. The resistance of the hot pressing plate 31 to the slider 341 when the hot pressing plate 31 is driven by the belt conveyor mechanism 2 can be adjusted as needed, thereby changing the moving speed of the hot pressing plate 31 when the starting speed of the belt conveyor mechanism 2 is fixed, so that the hot pressing plate 31 will not cause the core above it to shake when it moves.
