Description

Technical Field

[0001] This utility model relates to the field of capacitor manufacturing technology, and in particular to a vertical drying oven and capacitor production line. Background Technology

[0002] During the manufacturing process of capacitors, the leads and other components need to be potted with glue. To ensure a stronger bond, high-temperature baking is required to increase stability. For batch baking of capacitors, as shown in the figure, an oven is typically used. A tray 81 is placed inside the oven, and capacitors 82 are placed within the tray 81 for batch baking.

[0003] An existing oven includes a baking zone and a cooling zone. The baking zone includes a first loading zone for conveying a tray to be heated to a high-temperature zone and a first unloading zone for receiving trays that have finished baking. To increase heating time and reduce floor space, a first tray rising zone and a second tray descending zone are vertically arranged within the baking zone. The two zones are spaced apart and adjacent to each other. The tray is lifted by the first tray rising zone until it reaches the top of the first tray rising zone. Then, a first tray transfer mechanism transfers the tray from the top of the first tray rising zone to the top of the first tray descending zone. As the first tray descends, the tray is transported to the bottom and finally proceeds to other processes for further processing.

[0004] However, in the above technical solution, the trays in the first tray rising area and the first tray falling area are stacked vertically. The top surface of each tray has upward-extending bosses, and the bottom surface has grooves that fit these bosses. This means the upper and lower trays are mutually restrained in the horizontal direction, preventing them from coming off during transport. However, this method also requires that the tray be lifted first to release the restraints between the upper and lower trays before it can be transferred laterally. To facilitate tray lifting, the first tray transfer mechanism also includes grippers and guide rails for lifting the tray. In other words, the tray must be lifted during horizontal transfer, increasing both the time cost and the mechanism setup cost.

[0005] Secondly, in the above technical solution, because the material trays are stacked one on top of the other, the space between the material trays is relatively closed. The heating process is essentially about allowing hot air to fully contact the material in the tray. This stacking arrangement increases the difficulty for the material in the tray to come into contact with the hot air, making it difficult for the material to be fully heated. This may result in the material at the edge of the tray having a higher temperature and the material in the middle of the tray having a lower temperature, causing uneven product quality and affecting quality control. Utility Model Content

[0006] In view of this, the present invention provides a vertical drying oven to solve the problem of high difficulty in horizontal transfer and uneven heating caused by the stacking of material trays at the upper and lower limits in the prior art; the present invention also proposes a capacitor production line to solve the above-mentioned technical problems.

[0007] A vertical drying oven includes an ascending zone for lifting a tray and a descending zone for lowering the tray. The ascending and descending zones are arranged alternately. A transfer mechanism for transferring the trays within the ascending and descending zones is also provided between the ascending and descending zones. An ascending transmission assembly with circular rotation is provided in the ascending zone, and a descending transmission assembly with circular rotation is provided in the descending zone. Each transmission assembly includes a first flexible transmission ring and a second flexible transmission ring arranged in pairs and opposite to each other. Support brackets for supporting the trays are provided on the outer circumference of the two flexible transmission rings. The support brackets are arranged at intervals to form a hot air channel between two adjacent trays. The two sets of flexible transmission rings in the ascending zone are used to drive the trays to rise on one side opposite to each other, and the two sets of flexible transmission rings in the descending zone are used to drive the trays to fall on one side opposite to each other. Both the ascending and descending transmission assemblies include a detection module for detecting the rotational speed of the flexible transmission rings.

[0008] Furthermore, the ascending transmission assembly includes an ascending transmission shaft for driving the flexible transmission ring within its group to rotate, and the descending transmission assembly includes a descending transmission shaft for driving the flexible transmission ring within its group to rotate, with the ascending transmission shaft and the descending transmission shaft arranged coaxially.

[0009] Furthermore, the detection module includes a driven drive shaft for the upward or downward drive shaft of the leveling process, and the end of the driven drive shaft is provided with a photoelectric signal disk that can be driven by the driven drive shaft.

[0010] Furthermore, the transfer mechanism includes a guide rod disposed above the rising zone and the falling zone, the guide rod extending from the rising zone to the falling zone, a toggle structure slidably disposed on the guide rod, and the transfer mechanism also includes a direct drive power source for driving the toggle structure to move directly.

[0011] Furthermore, the direct drive power source includes a servo motor and a lead screw driven by the servo motor, and the actuation structure is provided with a threaded hole that mates with the lead screw.

[0012] Furthermore, the actuating structure includes a mounting plate guided on a guide rod and a toggle block fixedly mounted on the mounting plate, the toggle block having a claw protruding downward from the mounting plate.

[0013] Furthermore, the vertical oven includes a heating chamber body that forms a heating space for heating the tray and the material in the tray. An air inlet is provided on one side of the top of the heating chamber body, and an air outlet is provided on the other side of the top of the heating chamber body. An air inlet fan is provided at the air inlet to circulate the gas inside the heating chamber body.

[0014] Furthermore, the vertical oven also includes a heating compartment located at the top of the heating chamber, wherein a heater for heating the gas is provided in the heating compartment, and the heating compartment is connected to the air inlet and air outlet of the heating chamber, and the air inlet fan is located in the heating compartment.

[0015] Furthermore, the heater is located in the heating compartment at a position corresponding to the air outlet, and a filter structure for filtering the gas is also provided in the heating compartment between the heater and the air inlet fan.

[0016] The beneficial effects of the vertical drying oven in this invention are as follows: The vertical drying oven, by setting up rising and falling zones, facilitates extending the heating time of the trays. Furthermore, because the path is arranged vertically, it does not occupy excessive floor space. The transfer mechanism facilitates the transfer of trays within the rising and falling zones, enabling tray recycling. The rising and falling transmission components facilitate the rising and falling functions. The two relatively arranged flexible transmission rings in each zone facilitate continuous and smooth movement. The support brackets facilitate the support of the trays, allowing them to rise or fall with the transport of the flexible transmission rings. The trays are spaced apart, so after placing the trays, adjacent trays can maintain a distance from each other, which facilitates the entry of hot air between the trays and ensures sufficient heating of the material in the trays. Due to the use of a flexible transmission ring, the rising and falling of the trays no longer depends on their thickness, but on the rotational speed of the flexible transmission ring. By setting up a detection module, it is easy to monitor the conveying speed of the rising and falling areas in real time, so as to keep the speed of the rising and falling areas consistent. In other words, by setting up a new conveying method for the trays, it is easy to achieve the spaced arrangement of the trays, thereby solving the problem of high difficulty in horizontal transfer and uneven heating caused by the upper and lower limit stacking of trays in the prior art.

[0017] A capacitor production line includes a transmission line for transporting capacitors. Along the transmission line, from upstream to downstream, are a feeding machine, an energy-generating machine, a welding and assembly machine, an oven, a cooling machine, and a receiving machine. The oven includes an ascending zone for lifting trays and a descending zone for lowering trays. The ascending and descending zones are spaced apart. A transfer mechanism for transferring trays between the ascending and descending zones is provided. A circulating ascending transmission assembly is provided in the ascending zone, and a circulating descending transmission assembly is provided in the descending zone. Each transmission assembly includes a first flexible transmission ring and a second flexible transmission ring arranged in pairs and opposite to each other. Support brackets for supporting trays are provided on the outer circumference of the two flexible transmission rings. The support brackets are spaced apart to form a hot air channel between adjacent trays. The two sets of flexible transmission rings in the ascending zone are used to drive the trays upwards on one side, and the two sets of flexible transmission rings in the descending zone are used to drive the trays downwards on one side. Both the ascending and descending transmission assemblies include a detection module for detecting the rotational speed of the flexible transmission rings.

[0018] Furthermore, the ascending transmission assembly includes an ascending transmission shaft for driving the flexible transmission ring within its group to rotate, and the descending transmission assembly includes a descending transmission shaft for driving the flexible transmission ring within its group to rotate, with the ascending transmission shaft and the descending transmission shaft arranged coaxially.

[0019] Furthermore, the detection module includes a driven drive shaft for the upward or downward drive shaft of the leveling process, and the end of the driven drive shaft is provided with a photoelectric signal disk that can be driven by the driven drive shaft.

[0020] Furthermore, the transfer mechanism includes a guide rod disposed above the rising zone and the falling zone, the guide rod extending from the rising zone to the falling zone, a toggle structure slidably disposed on the guide rod, and the transfer mechanism also includes a direct drive power source for driving the toggle structure to move directly.

[0021] Furthermore, the direct drive power source includes a servo motor and a lead screw driven by the servo motor, and the actuation structure is provided with a threaded hole that mates with the lead screw.

[0022] Furthermore, the actuating structure includes a mounting plate guided on a guide rod and a toggle block fixedly mounted on the mounting plate, the toggle block having a claw protruding downward from the mounting plate.

[0023] Furthermore, the vertical oven includes a heating chamber body that forms a heating space for heating the tray and the material in the tray. An air inlet is provided on one side of the top of the heating chamber body, and an air outlet is provided on the other side of the top of the heating chamber body. An air inlet fan is provided at the air inlet to circulate the gas inside the heating chamber body.

[0024] Furthermore, the vertical oven also includes a heating compartment located at the top of the heating chamber, wherein a heater for heating the gas is provided in the heating compartment, and the heating compartment is connected to the air inlet and air outlet of the heating chamber, and the air inlet fan is located in the heating compartment.

[0025] Furthermore, the heater is located in the heating compartment at a position corresponding to the air outlet, and a filter structure for filtering the gas is also provided in the heating compartment between the heater and the air inlet fan.

[0026] The beneficial effects of the capacitor production line in this utility model are as follows: The capacitor production line facilitates capacitor production by setting up a transmission line and, on the transmission line, a feeding machine, an energy-generating machine, a welding and assembly machine, an oven, a cooling machine, and a receiving machine. The vertical oven, with its rising and falling zones, extends the heating time of the trays, and because the path is arranged vertically, it does not occupy excessive floor space. The transfer mechanism facilitates the transfer of trays within the rising and falling zones, enabling tray recycling. The rising and falling transmission components facilitate the rising and falling functions. The two relatively arranged flexible transmission rings in each area facilitate continuous and smooth movement. The support brackets provide convenient support for the trays. This facilitates the raising and lowering of the material trays along with the flexible transmission ring. Due to the spaced arrangement of the support brackets, adjacent trays can maintain a distance from each other after placement, allowing hot air to easily enter between the trays and fully heat the material inside. Because of the flexible transmission ring, the raising and lowering of the trays no longer depends on their thickness but on the rotational speed of the ring. A detection module allows for real-time monitoring of the rising and falling speeds, ensuring consistency between them. In other words, this new tray-carrying method facilitates spaced arrangement between trays, solving the problem of uneven heating and difficulty in horizontal transfer caused by the stacking of trays with upper and lower limits in existing technologies.

[0052] In the following description, the use of suffixes such as "module," "part," or "unit" to denote elements is solely for the purpose of illustrating this invention and has no specific meaning in itself. Therefore, "module" and "part" can be used interchangeably.

[0053] To better understand the technical solution of this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings.

[0054] In Embodiment 1 of the vertical drying oven of this utility model:

[0055] like Figure 2 and Figure 3As shown, in this embodiment, the vertical oven includes an ascending zone and a descending zone. The ascending zone is used to lift the material tray 81, and the descending zone is used to lower the material tray 81. A transfer mechanism is also provided between the ascending and descending zones to transfer the material tray 81 between them. In this embodiment, the ascending zone has a feed inlet, and the descending zone has a discharge outlet. That is, when the material tray 81 is heated, it is first lifted in the ascending zone, then transferred to the descending zone by the transfer mechanism, and then lowered. Of course, in other embodiments, the feed inlet can be located in the descending zone, and the discharge outlet can be located in the ascending zone. The material tray 81 enters the vertical oven, first descends, and then ascends. The vertical oven is used to heat incoming materials on the production line and transport the heated raw materials to the next stage for further processing. By setting up the ascending and descending zones, the floor space can be reduced, and the vertical space can be used to continuously heat the materials, extending the heating time.

[0056] like Figure 5 As shown, in order to realize the rising and falling of the material tray 81, a rising transmission component 2 with a circular rotation is provided in the rising area, and a falling transmission component 3 with a circular rotation is provided in the falling area. Both the rising transmission component 2 and the falling transmission component 3 include a first flexible transmission ring and a second flexible transmission ring arranged in a group and opposite to each other. The rising transmission component 2 and the falling transmission component 3 have the same structure and are arranged symmetrically to each other, only with different rotation directions. Therefore, the following description of the structure is based on the rising transmission component 2 as an example.

[0057] Specifically, such as Figure 3 and Figure 5As shown, the vertical oven has a box-type frame, with a heating chamber 11 and a door 12 arranged around the outer periphery of the frame, forming a closed box-type space. The ascending transmission assembly 2 and the descending transmission assembly 3 are both housed within this box-type space. The temperature inside the heating chamber 11 is high, therefore the transmission mechanism also needs to maintain good high-temperature resistance. The first flexible transmission ring consists of two spaced-apart first transmission chains 26, both driven by the same transmission shaft. The second flexible transmission ring consists of two spaced-apart second transmission chains 27, both driven by the same transmission shaft. The metal transmission chains can maintain good operation in high-temperature environments. Support brackets 261 are evenly spaced on the outer periphery of the first transmission chains 26, and correspondingly, support brackets 261 are also arranged on the outer periphery of the second transmission chains 27. The support brackets 261 are L-shaped, with one side welded to the transmission chain and the other side used to support the material tray 81. The height difference between two adjacent support brackets 261 is greater than the height of the tray 81, thus creating a channel for hot airflow between the two adjacent trays 81 after placement. The support brackets 261 on the first transmission chain 26 and the second transmission chain 27 are arranged correspondingly to facilitate support of the tray 81. During rotation, both the first transmission chain 26 and the second transmission chain 27 rotate cyclically, with the inner portion between them rising and the outer portion falling, allowing the tray 81 located between the two sets of transmission chains to continuously rise. Alternatively, in other embodiments, only one first transmission chain can be provided on one side and only one second transmission chain on the other, lengthening the first and second transmission chains to accommodate the support brackets. Or, in other embodiments, the support brackets can be configured as support blocks or other support forms.

[0058] To facilitate the rotation of the first transmission chain 26 and the second transmission chain 27, the lifting transmission assembly 2 includes a power source capable of driving the first transmission chain 26 and the second transmission chain 27, and the necessary transmission mechanism connected to the power source. For example... Figure 7 and Figure 8As shown, in this embodiment, the power source is a lifting drive motor 21. A lifting reducer 22 is connected to the output end of the lifting drive motor 21 to reduce the output torque of the lifting drive motor 21. The lifting reducer 22 is mounted on a bearing seat 29 via a bearing 28. The first transmission chain 26 contains a drive shaft for driving the first transmission chain 26 and another driven shaft. In this embodiment, the drive shaft is a lifting transmission shaft 25. A sprocket for driving the first transmission chain 26 is mounted on the lifting transmission shaft 25. A lifting worm gear 24 is also provided at one end of the lifting transmission shaft 25. The lifting reducer 22 is connected to a lifting worm 23 via a chain or other transmission mechanism. The rotation of the first transmission chain 26 is achieved through the cooperation of the worm gear and worm wheel. To facilitate the upward movement of the second transmission chain 27, a transmission rod is provided between the upward transmission shaft 25 of the first transmission chain 26 and the upward transmission shaft 25 of the second transmission chain 27. A single power source can simultaneously drive the movement of both transmission chains, saving on the arrangement of power sources and facilitating synchronization of the first and second transmission chains 26 through the transmission mechanism. Alternatively, in other embodiments, separate power sources can be provided for the first and second transmission chains 26 and 27. The transmission mechanism between the power source and the upward transmission shaft 25 can also be a gear set or other transmission method.

[0059] The descending transmission assembly 3 in the descending zone has the same structure as the ascending transmission assembly 2 in the ascending zone, with the ascending transmission shaft 25 and the descending transmission shaft arranged coaxially for easy alignment of the ascending and descending zones. Furthermore, the ascending transmission assembly 2 and the descending transmission assembly 3 are arranged symmetrically, allowing their respective power sources to be located close together for easy adjustment and installation. Of course, to maintain normal operation, the worm gears in the ascending transmission assembly 2 and the descending transmission assembly 3 rotate in opposite directions. In other embodiments, the ascending and descending transmission shafts can be arranged alternately, but their rotational speeds must still be kept the same. To achieve synchronization of the material trays 81 in the ascending and descending zones, the rotational speed of the motor in the ascending transmission assembly 2 is adjusted to match the rotational speed of the motor in the descending transmission assembly 3. In addition, their rotational speeds need to be detected to ensure that the transmission speeds are consistent, preventing material accumulation in the ascending zone or material shortage in the descending zone. Specifically, both the ascending transmission assembly 2 and the descending transmission assembly 3 are equipped with detection modules for detecting the rotational speeds of the first transmission chain 26 and the second transmission chain 27. The two detection modules have the same structure; this embodiment uses the detection module in the ascending transmission assembly 2 as an example for structural description.

[0060] like Figure 6As shown, the detection module includes a detection drive sprocket 41 mounted on the ascending drive shaft 25. The detection drive sprocket 41 is connected to a detection driven sprocket 42 via a detection chain 45. A photoelectric signal sensing disk 44 is located at the end of the detection driven sprocket 42 for detecting its rotational speed. Since the detection driven sprocket 42 and the detection drive sprocket 41 rotate with a fixed transmission ratio, the rotational speed of the detection drive sprocket 41 can be determined by detecting the rotational speed of the driven sprocket 42, and thus the rotational speed of the ascending drive shaft 25. To ensure the detection chain 45 is always taut, the detection driven sprocket 42 is mounted on a tension adjustment seat 43. The tension adjustment seat 43 can be adjusted vertically on the base to facilitate tensioning of the detection chain 45. Specifically, this can be achieved using a set screw or a screw installed vertically. Similarly, this method can also be used to detect the rotational speed of the descending drive shaft, allowing for easy determination of whether the two speeds are the same. If the speeds are different, timely adjustment is required. Of course, in other implementations, the detection module may be omitted, and the motor may be subject to more stringent control and regular maintenance.

[0061] like Figure 9 and Figure 10 As shown, to facilitate the transfer of the material tray 81 between the rising and falling zones, a transfer mechanism is provided at the top of both zones. The transfer mechanism includes a mounting base 57 on a box-type frame. Two guide rods 52 are spaced apart on the mounting base 57, extending from the rising zone to the falling zone. A mounting plate 54 is guided on the guide rod 52, and a lever 55 for actuating the material tray 81 is provided on the mounting plate 54. To avoid interference between the lever 55 and the box body, a gap naturally exists between the guide rod 52 and the box body, and the ends of the guide rods 52 are fixed to the box body. Two guide rods 52 are provided, arranged parallel and spaced apart. The lever 55 has a claw protruding downwards from the mounting plate 54, which facilitates the actuation of the material tray 81. To achieve the movement of the pawl, the transfer mechanism also includes a servo motor 56 and a lead screw 51 driven by the servo motor 56. A nut 53 is fixedly mounted on the mounting plate 54. The nut 53 cooperates with the lead screw 51 to convert the rotation of the lead screw 51 into the horizontal movement of the mounting plate 54, thereby driving the pawl to move horizontally. Since the material trays 81 are arranged vertically at intervals, the material trays 81 are only supported on the support bracket 261, and the movement of the material trays 81 can be achieved by horizontal tossing. The servo motor 56 makes the control more precise, avoiding overtravel or undertravel of the pawl 55, which would cause the material trays 81 to fail to transfer.

[0062] Of course, in other embodiments, the transfer mechanism may omit the pry block 55 and instead use an L-shaped mounting plate 54 with one side vertically downward. This downward-facing side of the mounting plate 54 can be used to pry the tray 81, facilitating its transfer. Alternatively, in other embodiments, the drive for the mounting plate 54 can be configured in other ways, such as using an electric actuator or cylinder, with the pushing mechanism located at the end of the actuator or cylinder. Or, in other embodiments, the guide rod 52 is omitted, and instead, a guide rail and grippers on the guide rail are provided between the rising and falling zones. The grippers clamp and lift the tray 81, thereby transferring it between the rising and falling zones.

[0063] like Figure 3 and Figure 4 As shown, the vertical drying oven is installed on the production line, naturally needing to receive the material trays 81 on the production line and place the heated material trays 81 back onto the production line at the discharge port. A feed inlet is provided in the rising zone, and a discharge port is provided in the descending zone; the feed inlet and discharge port are arranged at the same height for easy coordination with the same production line. A feed lifting door 14 is also provided at the feed inlet. Specifically, a feed lifting cylinder 141 is provided at the bottom of the feed lifting door 14, and a feed linear guide rail 142 is provided at the top of the feed lifting door 14, thus enabling the feed lifting door 14 to move only in the vertical direction. Correspondingly, a similar discharge lifting door is provided at the discharge port, which will not be described again here.

[0064] like Figure 11 As shown, a double-speed chain channel mechanism 6 is also provided to facilitate the transportation of materials from the production line to the support bracket 261. The double-speed chain channel mechanism 6 is located at the bottom of the rising and falling zones. It includes support legs 61 for placement on the ground and double-speed chains 62 arranged along the transmission direction. Two double-speed chains 62 are respectively arranged on opposite sides of the material tray 81. During transportation, the double-speed chains 62 can be transported between the first drive chain 26 and the second drive chain 27. When the first drive chain 26 and the second drive chain 27 rotate, the material tray 81 on the double-speed chains 62 is lifted by the support bracket 261. To drive the movement of the double-speed chains 62, a geared motor 63 is also provided. The geared motor 63 is located on one side and transmits power evenly to the double-speed chains 62 on both sides via a motor drive mechanism.

[0065] like Figure 12As shown, the basic function of the vertical oven is to heat the tray 81 and the items on it. Therefore, a heating structure is also required to heat the tray 81. In this embodiment, the heating space inside the heating chamber 11 is heated uniformly, creating a high-temperature environment within the heating chamber 11. This ensures that the tray 81 is continuously heated as soon as it enters through the inlet until it is discharged from the outlet. The top of the heating chamber 11 has spaced-apart air inlets and outlets, located on the left and right sides respectively. The top of the heating chamber 11 also has a heating compartment 13 for heating air, which is connected to the air inlets and outlets of the heating chamber 11. Hot air in the heating compartment 13 enters the heating chamber 11 through the air inlet, circulates within the heating chamber 11, and then returns to the heating compartment 13 through the air outlet.

[0066] To drive directional airflow, an intake fan is installed within the heating chamber 13. The intake fan blows air towards the air inlet of the heating box 11, creating positive pressure at the inlet. The airflow from the intake fan is vertically downwards, reaching the bottom of the heating box 11. On the other side, due to the positive pressure within the heating box 11, the pressure compresses the air, transporting it to the outlet. A heater 73 is installed near the outlet in the heating chamber 13 to reheat the air flowing out of the heating box 11, maintaining a constant temperature. Positioning the heater 73 at the outlet ensures better and more uniform mixing of the heated air before it enters the heating box 11, resulting in more even heating of the material on the tray 81. Since the air may be contaminated during circulation, a filter structure 72 is installed between the heater 73 and the intake fan in the heating chamber 13 to filter the air and maintain its cleanliness. Of course, in other embodiments, the filter structure 72 can be placed in other locations, such as at the air inlet, or the filter structure 72 can be omitted altogether. Alternatively, in other embodiments, the air intake fan and the heater 73 can be placed in one location. Alternatively, in other embodiments, the heating compartment 13 can be omitted, and the heater 73 can be placed at the air inlet inside the heating box 11.

[0067] When it is necessary to heat the material tray 81 and the material inside the material tray 81, the material tray 81 filled with material is placed on the production line, and the material tray 81 is transported to the double speed chain 62 channel through the feed port, and enters the heating box 11 through the feed port. Then, with the rotation of the first transmission chain 26 and the second transmission chain 27, the material tray 81 is lifted, and then enters the descending area through the transfer mechanism. Finally, it is sent out at the discharge port as it descends.

[0068] In an embodiment of the capacitor production line of this utility model:

[0069] Capacitor 82 includes a component that performs the main function. The component is connected to other components via pins, and a plastic shell is disposed around the component. To secure the component within the shell, glue is typically poured inside the shell to cure the component. In this embodiment, the capacitor production line mainly automates the assembly of capacitor 82. Figure 13 As shown, the capacitor production line includes a transmission line. Upstream and downstream of the transmission line are a feeding machine for loading capacitor elements, an energizing machine 92 for testing the functionality of the elements, and a welding assembly machine 93 for welding the leads of the elements. After welding, the leads need to be tidied, so a lead aligner 95 is provided. Finally, a receiving machine 97 is located below the transmission line to collect the assembled capacitors 82. To facilitate the installation of the elements within the plastic casing, a glue injection machine 942 and an oven located downstream of the glue injection machine 942 are also provided. The glue injection process involves multiple injections. The first injection is performed at the welding assembly machine 93. Additionally, a glue injection machine 942 is also located at the lead aligner 95. Between the welding assembly machine 93 and the lead aligner 95, a glue injection machine 942 and a vacuum machine 94 are also provided. An oven is located downstream of each glue injection machine 942 to ensure a tight bond between the glue and the elements after injection. The oven in this embodiment is the vertical oven 1 in the aforementioned vertical oven 1 embodiment.

[0070] Specifically, such as Figure 14 As shown, the feeding machine is a vision-based feeding machine 91, equipped with a spider arm 915. A hopper 912 is also provided on the feeding machine, containing elements with leads to be soldered. A feeding channel 913 transports these elements. Between the hopper 912 and the feeding channel 913, a lifting channel 911 is provided for transferring elements. The lifting channel 911 is angled to transport elements from the bottom hopper 912 to the feeding channel 913. Afterward, the elements are inspected by a detection box 914 located on the feeding channel 913. Then, the spider arm 915 picks up the elements and transfers them to the power-enhancing machine 92. During the transfer process, obviously defective elements are screened out by the spider arm 915, meaning that some defective elements have already been eliminated before being transferred to the power-enhancing machine 92. Meanwhile, a return channel 916 is also set on the feeder. The rising speed of the element in the feeder is not necessarily the same as the energizing and welding speed behind it. When the element is fed too fast, it can be transported back to the hopper 912 through the return channel 916 for easy feeding next time.

[0071] The main function of the power generator 92 is to perform power generator testing on the elements, including removing defective products, testing the element's capacity, and testing its withstand voltage. It removes elements that do not meet the requirements and retains only the qualified ones, so that only the elements that meet the requirements (capacitor 82) can be processed, avoiding the waste of resources and time caused by processing unqualified elements.

[0072] like Figure 15 As shown, the pins of the capacitor 82 need to be soldered to fulfill its basic function. The soldering assembly machine 93 includes a main body 931, a water cooler 932, a core feeding channel 913, a wire feeder, an inverter power supply 935, a plastic shell feeding channel 936, and a wide belt feeder 937. The soldering of the core pins, the dispensing of the plastic shell, and the insertion of the core shell all take place on the main body 931. The water cooler 932 primarily cools the capacitor 82 during pin soldering to prevent overheating and damage. The core feeding channel 913 transports the core to the soldering station. The wire feeder ensures stable and unobstructed lead wire flow and allows for the replacement of the wire in tubs as needed; the fed wire also forms the pins of the capacitor 82. The inverter power supply 935 provides high-voltage power for lead wire soldering, acting on the core pin soldering points. The wide belt conveyor 937 and the plastic shell feeding channel 936 work together to deliver the plastic shells to the assembly tray of the welding assembly machine 93. The plastic shell feeding channel 936 can be integrated with the wide belt conveyor 937 or with the multi-lead welding assembly machine 93. Furthermore, the welding assembly machine 93 is equipped with a glue injection machine 942 (not shown in the figure) to facilitate the injection of glue into the plastic shell, thus facilitating the fixation of the elements within the shell.

[0073] The capacitor 82 with its soldered pins is then transported to the vertical oven 1 via the double-speed chain channel mechanism 6 on the transmission line. The vertical oven 1 heats the capacitor 82, facilitating the bonding of the capacitor and the plastic shell with adhesive. It is worth noting that the vertical oven 1 used in this embodiment has the same structure as the vertical oven 1 in the above-described embodiment, and will not be described again here.

[0074] During the assembly of the substrate and the plastic shell using adhesive injection, the substrate needs to be completely surrounded by adhesive, with only the leads exposed. Since the adhesive is liquid before solidification, injecting all the adhesive at once would make it difficult to control the substrate's position within the shell. Therefore, the welding assembly machine 93 does not inject all the adhesive at once, but in multiple stages. First, the bottom of the shell is filled with adhesive, fixing the substrate inside. Then, after the adhesive at the bottom of the shell solidifies, another injection is performed to fill the area around the substrate. After the second injection solidifies, a third injection is performed, filling the surface of the substrate with adhesive. After solidification, this secures the substrate. To improve the adhesive bonding effect, heating is required after each injection; therefore, a vertical drying oven 1 is installed downstream of each adhesive injection machine 942.

[0075] like Figure 16 As shown, after exiting the first vertical oven 1, a vacuum pump 94 is also installed on the production line. The vacuum pump 94 includes a vacuum feed channel 941 for connecting to the upstream capacitor 82, a vacuum chamber 943, and a vacuum discharge channel 944. Specifically, there are two vacuum chambers 943, arranged in parallel with the vacuum feed channel 941. A glue dispensing machine 942 is also installed on the vacuum chamber 943 to dispense glue onto the plastic shell of the capacitor 82 entering the vacuum chamber 943, thus completing the second glue dispensing. This glue dispensing involves a large amount of glue, and because it is distributed around the core components, it is quite important. To improve the versatility of the production line, two vacuum chambers 943 are installed, each with a different glue dispensing machine 942. To increase the types of glue dispensed, each vacuum chamber 943 corresponds to two glue dispensing machines 942, allowing for the simultaneous replacement of four types of glue. Two vacuum chambers 943 correspond to the same vacuum discharge channel 944. Regardless of the type of adhesive injected, it must flow out from a single outlet for convenient subsequent operations. A second vertical drying oven 1 is then located downstream of the vacuum pump 94 to heat the capacitor 82 exiting the vacuum pump 94, improving the adhesive's bonding effect. Alternatively, in other embodiments, one vacuum chamber 943 or three or more vacuum chambers 943 can be used. Furthermore, in other embodiments, a dispensing machine 942 can be provided for each vacuum chamber 943, or three or more vacuum chambers 943 can be used.

[0076] After the second gluing is completed, the substrate is fixed, with only the top surface and leads exposed. The leads are thin metal leads, which are easily bent under external force. During transfer or previous production processes, the leads may be bent by external force. Therefore, if... Figure 17As shown, this embodiment also includes a lead straightening machine 95 for tidying up the leads. The lead straightening machine 95 includes a lead straightening machine body 951, a conversion and layout device 952, and aluminum strips 953. After the capacitor 82 enters the lead straightening machine body 951, the internal structure of the lead straightening machine 95 will correct the leads of the capacitor 82. For the corrected capacitor 82, the aluminum strips 953 are used to neatly arrange the capacitor 82 onto the mold. Then the mold carries the capacitor 82 to the next stage. In addition, after the lead straightening, the capacitor 82 needs to be injected with glue for the third time. In this embodiment, a third glue injection machine 942 is also provided in the lead straightening machine 95. The glue injection machine 942 injects glue onto the upper surface of the capacitor 82 to complete the sealing of the lead. Correspondingly, a third vertical oven 1 is also provided below the lead straightening machine 95 to heat the capacitor 82 to achieve a good bonding effect. Of course, in other embodiments, the lead straightening machine 95 and the glue injection machine 942 can be set separately.

[0077] After passing through the third vertical oven 1, capacitor 82 has been assembled and needs to be transported downstream for processing or packaging. Since capacitor 82 is at a high temperature after being heated by the vertical oven 1, a cooling fan box 96 is also provided to cool it. In this embodiment, the structure of the cooling fan box 96 is similar to that of the vertical oven 1, the only difference being the reduction of the heating module in the vertical oven 1; therefore, the cooling fan box 96 will not be described again.

[0078] like Figure 18 As shown, the cooled capacitors 82 need to be collected and stored. Therefore, a receiving machine 97 is installed at the end of the production line. The receiving machine 97 includes a receiving frame 971, an aluminum strip receiving device 972, a discharge channel 973, and a lifting and translating device 974. The capacitors 82 flowing from the upstream to the downstream of the production line enter the receiving machine 97. The lifting and translating device 974 separates the capacitors 82, aluminum strips 953, and trays 81. The aluminum strips 953 are sent to the aluminum strip receiving device 972 to separate and collect the trays 81. The capacitors 82 on top are sent out of the receiving machine 97 through the discharge channel 973. The empty trays 81 are then lowered into the return channel 916 by the lifting and translating device 974 and sent back to the oven feed end for recycling.

[0079] It should be understood that the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
