Description

Technical Field

[0001] This utility model relates to the technical field of chip capacitor production equipment, and in particular to a cooling and storage mechanism for sealing chip capacitor terminals. 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 existing technologies, due to the heavy weight of the thick plastic sheet, the handling between each step of the sealing process is generally done manually. Furthermore, to facilitate maintenance of the corresponding equipment in each step, a certain distance is usually maintained between each step. Therefore, the cooling air blown out during the end-cooling process of the surface mount capacitor generally does not affect the internal temperature of the oven in the end-drying process.

[0005] Shortening the transfer distance between processes is a simple and effective measure to improve the sealing efficiency of surface mount capacitors. However, if the distance between the cooling process and the drying process is too short, the cooling air blown out by the cooling process at the end of the surface mount capacitor can easily enter the oven directly from the discharge end, thus affecting the temperature profile of the drying process and reducing the drying efficiency and quality of the surface mount capacitor ends.

[0013] The inner conveying sections of the conveyor belts of the two conveying assemblies have the same conveying direction and are synchronized, and the pallets of the two conveying assemblies are used together to support the thick rubber sheet.

[0014] Preferably, the conveying assembly further includes a driving wheel and a driven wheel, both of which are rotatably mounted on the same side of the vertical conveyor frame, with the driving wheel protruding from the lower part of the vertical conveyor frame and the driven wheel protruding from the upper part of the vertical conveyor frame;

It can also make the cold air effectively gather inside the cooling hood, thereby improving the cooling efficiency of the chip capacitor end. Attached Figure Description

[0030] Thick rubber sheet 93. Detailed Implementation

[0031] 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.

[0032] This technical solution provides a cooling storage mechanism for sealing the terminals of surface mount capacitors, including a cooling cover 61, a lifting device 62, a cold air conveying head 63, and a circulating fan 64; the cooling cover 61 has openings at both the bottom and the top, the lifting device 62 is disposed inside the cooling cover 61, and the inlet of the lifting device 62 protrudes from the bottom of the cooling cover 61, the lifting device 62 is used to convey the thick plastic plate 93 upward in the vertical direction;

[0033] The cold air conveying head 63 is connected to the cooling cover 61, and the air inlet of the cold air conveying head 63 is connected to the cold air source.

[0034] The circulating fan 64 is installed between the cooling cover 61 and the lifting device 62, and the circulating fan 64 is located below the cold air delivery head 63.

[0035] In existing technologies, due to the heavy weight of the thick plastic sheet, the handling between each step of the sealing process is generally done manually. Furthermore, to facilitate maintenance of the corresponding equipment in each step, a certain distance is usually maintained between each step. Therefore, the cooling air blown out during the end-cooling process of the surface mount capacitor generally does not affect the internal temperature of the oven in the end-drying process.

[0036] Shortening the transfer distance between processes is a simple and effective measure to improve the sealing efficiency of surface mount capacitors. However, if the distance between the cooling process and the drying process is too short, the cooling air blown out by the cooling process at the end of the surface mount capacitor can easily enter the oven directly from the discharge end, thus affecting the temperature profile of the drying process and reducing the drying efficiency and quality of the surface mount capacitor ends.

[0037] Therefore, in order to solve the above-mentioned technical problems, this technical solution proposes a cooling storage mechanism, such as... Figure 1-5As shown, it includes a cooling shroud 61, a lifting device 62, a cold air conveyor head 63, and a circulating fan 64. The gas flow direction within the cooling storage mechanism is as follows: Figure 4 As shown, the cold air conveyor head 63 is used to convey cold air into the interior of the cooling shroud 61 (indicated by the hollow arrow), thereby cooling the thick plastic plate 93 that is conveyed vertically upward inside the cooling shroud 61; the circulating fan 64 is used to form a circulating airflow at the bottom of the cooling shroud 61 (indicated by the solid arrow), and this circulating airflow can act as an air curtain to prevent the cold air conveyed by the cold air conveyor head 63 from sinking into the interior of the cooling shroud 61 and thus being lost through the bottom opening of the cooling shroud 61, or even affecting the drying process in the previous step. It can also make the cold air effectively gather inside the cooling shroud 61, thereby improving the cooling efficiency of the chip capacitor end.

[0038] Specifically, the operation process of the cooling storage mechanism in this solution includes the following steps:

[0039] (1) The thick plastic plate 93 with embedded chip capacitors enters the cooling storage mechanism from the bottom of the lifting device 62, and is driven upward by the lifting device 62 into the interior of the cooling cover 61.

[0040] (2) Cold air is delivered to the interior of the cooling cover 61 via the cold air conveyor head 63, so that the thick plastic plate 93 with embedded chip capacitors is effectively cooled as it is lifted upward by the lifting device 62.

[0041] (3) After cooling, the thick plastic plate 93 with embedded chip capacitors is unloaded from the top of the cooling cover 61 and moved to the next process by conventional transfer mechanisms such as transfer grippers (not shown in the figure).

[0042] To further explain, the lifting device 62 includes two conveying components 621 arranged opposite each other in the vertical direction, and a conveying gap is left between the two conveying components 621;

[0043] The conveying assembly 621 includes a vertical conveyor frame 6211, a conveyor belt 6212, and pallets 6213. The conveyor belt 6212 rotates relative to the vertical conveyor frame 6211. Multiple pallets 6213 are provided and are spaced apart on the outer side of the conveyor belt 6212. The pallets 6213 rotate with the conveyor belt 6212.

[0044] The inner conveying sections of the conveyor belts 6212 of the two conveying assemblies 621 have the same conveying direction and are synchronized. The pallets 6213 of the two conveying assemblies 621 are used together to support the thick rubber plate 93.

[0045] In a preferred embodiment of this technical solution, the lifting device 62 includes two vertically oriented conveying components 621 arranged opposite each other, with a conveying gap between the two conveying components 621 to allow the thick rubber sheet 93 to rise within the conveying gap. Specifically, the conveying component 621 of this solution includes a vertical conveyor frame 6211, a conveyor belt 6212, and a support plate 6213, and the support plate 6213 for supporting the thick rubber sheet 93 rotates along with the rotation of the conveyor belt 6212. When the inner conveying sections of the conveyor belts 6212 of the two conveying components 621 are conveyed synchronously upward, and the thick rubber sheet 93 is placed on the support plate 6213 of the two conveying components 621, the thick rubber sheet 93 can rise vertically within the conveying gap.

[0046] The lifting device 62 in this design has a simple structure and reliable performance, and can stably lift the thick rubber plate 93 in the vertical direction. Furthermore, the lifting device 62 consists of two symmetrical conveying components 621, which helps to reduce the design cost of the lifting device 62 while ensuring stable performance.

[0047] Furthermore, the conveying assembly 621 also includes a driving wheel 6214 and a driven wheel 6215. The driving wheel 6214 and the driven wheel 6215 are rotatably mounted on the same side of the vertical conveyor frame 6211, with the driving wheel 6214 protruding from the lower part of the vertical conveyor frame 6211 and the driven wheel 6215 protruding from the upper part of the vertical conveyor frame 6211.

[0048] The conveyor belt 6212 surrounds the outside of the drive wheel 6214 and the driven wheel 6215, and the rotation of the drive wheel 6214 drives the rotation of the conveyor belt 6212.

[0049] To further explain, the driving wheel 6214, the driven wheel 6215 and the conveyor belt 6212 are a set of lifting members, and the conveying assembly 621 includes two sets of lifting members, and the two sets of lifting members are respectively arranged on opposite sides of the vertical conveyor frame 6211.

[0050] The support plates 6213 of the two sets of lifting components are used together to support one side of the thick rubber plate 93.

[0051] This provides the thick rubber plate 93 with four support points during its upward movement, which is more conducive to the stable ascent of the thick rubber plate 93.

[0052] To further clarify, both the driving wheel 6214 and the driven wheel 6215 are sprockets, and the conveyor belt 6212 is a chain.

[0053] In a more preferred embodiment of this technical solution, the transmission method of the conveying component 621 is preferably chain drive. On the one hand, since chain drive has no elastic slippage or slippage, it is beneficial to improve its transmission efficiency. On the other hand, it can transmit greater power and has strong overload capacity, thus effectively improving the support capacity of the conveying component 621 for the heavy thick rubber plate 93.

[0054] To further explain, the tray 6213 includes a connecting piece 62131 and a supporting piece 62132, and the connecting piece 62131 and the supporting piece 62132 are perpendicular to each other;

[0055] The connecting piece 62131 is connected to the outer side of the conveyor belt 6212, and the long side of the supporting piece 62132 is integrally formed with the long side of the connecting piece 62131.

[0056] When the pallet 6213 is located inside the conveying gap, the support piece 62132 is located on top of the connecting piece 62131.

[0057] In another preferred embodiment of this technical solution, the pallet 6213 includes a connecting piece 62131 and a supporting piece 62132. The connecting piece 62131 is used to connect with the conveyor belt 6212, and the supporting piece 62132 is used to support the thick rubber plate 93 so as to achieve stable conveying of the thick rubber plate 93.

[0058] In addition, since the support plate 62132 is located on top of the connecting plate 62131 when the pallet 6213 is inside the conveying gap, the support plate 62132 can effectively prevent the obstruction of the feeding action during the feeding process of the thick rubber plate 93, so as to achieve smooth feeding of the thick rubber plate 93.
