Description

Technical Field

[0001] This utility model relates to the technical field of chip capacitor production equipment, and in particular to a chip capacitor unloading mechanism based on a thick adhesive plate. Background Technology

[0002] Currently, fully automated end-sealing machines / production lines for surface mount capacitors typically use a stencil as the carrier for transferring the capacitors. Specifically, as detailed in Chinese Utility Model Patent CN218849426U, the end-sealing process involves first applying an adhesive film to one side of the stencil to seal one end of the mesh. After the film is smoothly adhered, the surface mount capacitors are inserted into the mesh, and the adhesive film adheres hundreds of miniature capacitors to the stencil, preventing them from falling off. Then, the other end of the capacitors without adhesive film is dipped in resin for end-sealing. During this insertion process, the ends of the surface mount capacitors are aligned by the adhesive film. However, due to potential manufacturing tolerances (such as varying lengths) in the surface mount capacitors themselves, the ends to be sealed within the same stencil are difficult to align perfectly after insertion, resulting in poor consistency in the resin dipping process and significantly affecting the end-sealing quality.

[0003] Therefore, to ensure the sealing quality of surface mount capacitors, some manufacturers have begun to use thick plastic plates instead of stencils as the transport carrier for surface mount capacitors. The thick plastic plate is a carrier that fixes the surface mount capacitor using silicone clamps. Therefore, to successfully implant the surface mount capacitor into the holes of the thick plastic plate, a guide plate needs to be placed on top of the thick plastic plate. First, the surface mount capacitor is implanted into the guide hole of the guide plate by vibration. Then, a bed of needles presses the surface mount capacitor located in the guide plate into the hole of the thick plastic plate, thus completing the implantation process of the surface mount capacitor into the thick plastic plate.

[0004] In the end-capsulation process of surface mount capacitor manufacturing, after the end-capsulation of the surface mount capacitors on the end-capsulation carrier board is completed, they need to be unloaded into a receiving box. In common production, only one receiving box is installed on the unloading machine. With this type of unloading machine, the receiving box can only be picked up and put in manually, and only one box can be replaced at a time, which may require 10-30 replacements. This single-box unloading method has the disadvantages of small box capacity, which cannot support long-term automatic large-capacity unloading. After a certain number of boxes are received, the machine needs to be stopped for processing. The full box needs to be removed manually and replaced with a new box before production can continue. This results in frequent manual operations, which are time-consuming and labor-intensive, seriously affecting the overall line efficiency and leading to low production efficiency.

[0036] Material box 95. Detailed Implementation

[0037] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0038] This technical solution provides a chip capacitor unloading mechanism based on a thick adhesive plate, including an unloading conveying device 81, a needle bed unloading device 82, a loading conveying device 83, a full material conveying device 84, an empty material box storage rack 85, a full material box storage rack 86, and a material box moving device 87.

[0039] The unloading conveying device 81 includes an unloading conveying frame 811 and an unloading platform 812. The unloading platform 812 is horizontally movably installed on the top of the unloading conveying frame 811 and is used to hold the thick rubber sheet to be unloaded. The bottom of the unloading platform 812 is provided with a discharge port 8121, and the middle of the unloading conveying frame 811 is provided with a discharge notch 8111. The discharge port 8121 and the discharge notch 8111 are matched with each other.

[0040] The needle bed unloading device 82 is mounted above the unloading conveyor frame 811, and the material conveying device 83 is located below the unloading conveyor frame 811. The unloading ends of the needle bed unloading device 82, the unloading notch 8111, and the material conveying device 83 are arranged sequentially from top to bottom. The needle bed unloading device 82 can move up and down relative to the unloading conveyor frame 811, and the needle bed unloading device 82 is used to press the patch capacitors away from the thick adhesive plate.

[0041] The material conveying device 83 and the full material conveying device 84 are arranged side by side, and the empty material box storage rack 85, the plate changing end of the material conveying device 83 and the loading end of the full material conveying device 84 are sequentially arranged within the transfer range of the material box moving device 87. The unloading end of the full material conveying device 84 is connected to the full material box storage rack 86.

[0042] The empty material box storage rack 85 is used to store multiple stacked material boxes 95. The material conveying device 83 and the full material conveying device 84 are both used to convey the material boxes 95. The full material conveying device 84 is also used to convey the material boxes 95 to the full material box storage rack 86. The material box moving device 87 is used to transfer the material boxes 95.

[0043] In the end-capsulation process of surface mount capacitor manufacturing, after the end-capsulation of the surface mount capacitors on the end-capsulation carrier board is completed, they need to be unloaded into a receiving box. In common production, only one receiving box is installed on the unloading machine. With this type of unloading machine, the receiving box can only be picked up and put in manually, and only one box can be replaced at a time, which may require 10-30 replacements. This single-box unloading method has the disadvantages of small box capacity, which cannot support long-term automatic large-capacity unloading. After a certain number of boxes are received, the machine needs to be stopped for processing. The full box needs to be removed manually and replaced with a new box before production can continue. This results in frequent manual operations, which are time-consuming and labor-intensive, seriously affecting the overall line efficiency and leading to low production efficiency.

[0044] Therefore, in order to achieve continuous unloading of surface mount capacitors with large capacitance without shutdown, this technical solution proposes an unloading mechanism, such as... Figure 1-5 As shown, the device includes an unloading conveyor 81, a needle bed unloading device 82, a loading conveyor 83, a full material conveyor 84, an empty material box storage rack 85, a full material box storage rack 86, and a material box moving device 87. The empty material boxes 95 can be transferred sequentially between the empty material box storage rack 85, the loading conveyor 83, the full material conveyor 84, and the full material box storage rack 86. This allows the unloading mechanism of this solution to automatically load empty material boxes and automatically unload full material boxes filled with chip capacitors. This overcomes the technical defects of the existing single material box unloading method, which has a small material box capacity and cannot support long-term automatic large-capacity unloading.

[0045] Specifically, the unloading process of the unloading mechanism in this solution includes the following steps:

[0046] (1) The thick plastic plate to be unloaded (not shown in the figure) is rotated from the previous process to the top of the unloading platform 812, and at this time the end of the chip capacitor embedded in the thick plastic plate protrudes from its lower surface, and the unloading port 8121 is used to avoid the chip capacitor.

[0047] (2) The thick rubber sheet to be unloaded is moved to the underside of the needle bed unloading device 82 using the unloading platform 812; at the same time, the empty material box 95 is moved from the empty material box storage rack 85 to the changing end of the material conveying device 83 using the material box moving device 87, and the empty material box is conveyed to its unloading end by the material conveying device 83.

[0048] (3) The needle bed unloading device 82 moves downward relative to the unloading conveyor frame 811 and presses the chip capacitor away from the thick rubber plate. The unloaded chip capacitor passes through the unloading notch 8111 and falls into the empty material box at the unloading end of the loading conveyor device 83.

[0049] (4) After the empty material box at the unloading end of the above-mentioned material conveying device 83 is filled with chip capacitors (hereinafter referred to as "full material box"), it is conveyed by the material conveying device 83 to its changing plate end.

[0050] (5) The full material box is moved from the tray changing end of the material conveying device 83 to the full material conveying device 84 using the material box moving device 87, and then conveyed by the full material conveying device 84 to the full material box storage rack 86 for storage; at the same time, the new empty material box is moved from the empty material box storage rack 85 to the tray changing end of the material conveying device 83 using the material box moving device 87 for the next round of unloading and receiving, and so on.

[0051] Furthermore, the unloading conveying device 81 also includes a limiting frame 813, which is installed in the middle of the unloading conveying frame 811, and the unloading notch 8111 is provided in the middle of the limiting frame 813.

[0052] The material conveying device 83 includes a material conveying frame 831, a material carrying platform 832, and a material box lifting seat 833. The material carrying platform 832 is horizontally movably installed on the top of the material conveying frame 831 and is used to hold the material box 95. The material box lifting seat 833 is vertically movably installed on the unloading end of the material conveying frame 831 and is located directly below the unloading notch 8111.

[0053] The material box lifting seat 833 is used to lift the material box 95 and make the material box 95 abut against the limiting frame 813.

[0054] In a preferred embodiment of this technical solution, the unloading conveying device 81 is further provided with a limiting frame 813, and the loading conveying device 83 is provided with a material box lifting seat 833 for realizing the vertical movement of the material box 95. Specifically, when the material box 95 is conveyed to the unloading end by the loading platform 832 of the loading conveying device 83 for unloading and receiving, the material box 95 can be lifted by the material box lifting seat 833 to abut against the bottom of the limiting frame 813, thereby effectively shortening the unloading drop distance of the chip capacitor and avoiding adverse effects on the sealing quality of the chip capacitor during the unloading process.

[0055] To further explain, the full material conveying device 84 includes a full material conveying frame 841 and a material unloading pusher 842;

[0056] The top two sides of the full material conveying frame 841 are provided with a plurality of rotating conveying wheels 8411, and the rotation axis of the conveying wheels 8411 is perpendicular to the conveying direction of the full material conveying device 84.

[0057] The material feeding pusher 842 is horizontally movable and installed on the top of the full material conveyor 841. The material feeding pusher 842 is located near the feeding end of the full material conveyor 841. The material feeding pusher 842 is used to push the full material box 95 to the full material box storage rack 86.

[0058] In another preferred embodiment of this technical solution, the full material conveying device 84 includes a full material conveying frame 841 and a discharge pusher 842, and multiple rotating conveying wheels 8411 are provided on both sides of the top of the full material conveying frame 841. When the full material box is moved from the tray-changing end of the material conveying device 83 to the full material conveying device 84 by the material box moving device 87, the full material box can be easily and simply moved to the full material box storage rack 86 by the cooperation of the discharge pusher 842 and the conveying wheels 8411. The structure is simple and the performance is reliable.

[0059] To further explain, the material box moving device 87 includes a moving crossbeam 871, an empty material box loading gripper 872, and a full material box unloading gripper 873;

[0060] The movable crossbeam 871 is installed above the material conveying device 83 and the full material conveying device 84, and the extending direction of the movable crossbeam 871 is perpendicular to the conveying direction of the material conveying device 83.

[0061] The empty material box loading claw 872 and the full material box unloading claw 873 can both be horizontally mounted on the moving crossbeam 871, and the empty material box loading claw 872 and the full material box unloading claw 873 can both move up and down relative to the moving crossbeam 871.

[0062] The empty material box loading gripper 872 is used to transfer the material box 95 located in the empty material box storage rack 85 to the changing plate end of the material conveying device 83, and the full material box unloading gripper 873 is used to transfer the material box 95 located in the changing plate end of the material conveying device 83 to the loading end of the full material conveying device 84.

[0063] Specifically, the material box moving device 87 used to realize the material box 95 in this solution includes an empty material box loading gripper 872 for moving empty material boxes and a full material box unloading gripper 873 for moving full material boxes. The setting of the two grippers can effectively improve the moving speed of the material box 95, thereby improving the replacement efficiency of the material box 95.

[0064] It should be noted that the empty material box loading gripper 872 and the full material box unloading gripper 873 in this solution are conventional clamps in the field. The above clamps can clamp and release the clamped object. The specific structure of the clamps will not be described in detail here.

[0065] To further explain, the empty material box loading claw 872 and the full material box unloading claw 873 move synchronously, and the empty material box storage rack 85 moves up and down relative to the moving crossbeam 871.

[0066] As a further improvement of the above embodiment, in order to further improve the replacement efficiency of the material box 95, this solution optimizes the structure of the material box moving device 87 and the empty material box storage rack 85. That is, the empty material box storage rack 85 moves up and down relative to the moving crossbeam 871, and through its up and down movement, the material picking surface of the empty material box storage rack 85 is aligned with the conveying surfaces of the material conveying device 83 and the full material conveying device 84, so that the empty material box and the full material box can move synchronously, which greatly improves the replacement speed of the material box 95.

[0067] To further explain, the interior of the full material box storage rack 86 is provided with multiple storage positions along the vertical direction, and the full material box storage rack 86 can move up and down relative to the full material conveying rack 841.

[0068] In a preferred embodiment of this technical solution, the interior of the full-box storage rack 86 is provided with multiple storage positions along the vertical direction, and it can move up and down relative to the full-box conveyor rack 841. This effectively reduces the space occupied by the full-box storage rack 86 while achieving large-capacity storage of surface-mount capacitors. Furthermore, the up-and-down movement of the full-box storage rack 86 ensures that the conveying surface of the full-box conveyor 84 is always flush with the top of the corresponding storage position, facilitating the horizontal conveying of full-boxes to the full-box storage rack 86 for storage.

[0069] To further explain, multiple full-load storage racks 86 are provided, and multiple full-load storage racks 86 are arranged side by side;

[0070] The full material box storage rack 86 can move horizontally relative to the full material conveying rack 841, and the direction of movement of the full material box storage rack 86 is perpendicular to the extension direction of the full material conveying rack 841.

[0071] As a further improvement of the above embodiment, the full-box storage rack 86 is provided in multiple ways and can move horizontally relative to the full-box conveyor rack 841, which further increases the full-box storage capacity of the unloading mechanism.

[0072] To further explain, the needle bed unloading device 82 includes a needle bed unloading seat 821 and an unloading plate 822. The unloading plate 822 is installed below the needle bed unloading seat 821 by means of a spring. Multiple pressure needles are protruding from the lower surface of the needle bed unloading seat 821. Multiple through holes are opened on the surface of the unloading plate 822, and one pressure needle corresponds to one through hole. The through holes are used for the pressure needles to pass through the unloading plate 822.
