Description

Technical Field

[0001] This utility model application belongs to the field of tantalum capacitor welding and assembly technology, specifically relating to a tantalum capacitor and a workpiece welding production line. Background Technology

[0002] Tantalum capacitors, as high-performance capacitors, are widely used in electronic devices. The manufacturing process typically involves soldering the tantalum capacitor core onto leads to form a complete tantalum capacitor assembly. Leads generally come in two types: common metal solderable parts and, more recently, circuit boards. The assembly and soldering speed of the tantalum capacitor core onto the leads is a crucial factor determining the manufacturing cost of tantalum capacitors, directly impacting the manufacturing efficiency and economic benefits of tantalum capacitor assemblies.

[0003] For tantalum capacitors using circuit boards as leads, various welding and assembly techniques have been proposed. For example, invention patent application CN115722845A discloses a process flow: In the production of tantalum capacitors, firstly, tantalum wires from multiple tantalum blocks are welded in rows onto stainless steel strips to form so-called process strips. After subsequent processes (such as anodizing), the tantalum blocks are transformed into tantalum capacitor cores; subsequently, the process strips enter the packaging process. In the packaging process, the tantalum capacitor core needs to be transferred from the stainless steel strip to the lead body (i.e., the circuit board). The process includes: welding the tantalum wire on the tantalum capacitor core to the positive lead end of the circuit board at a high temperature, welding the conductive layer on the outer surface of the tantalum capacitor core to the negative lead end of the circuit board, and finally encapsulating the entire core externally so that the positive and negative lead ends form positive and negative electrodes outside the package. This greatly facilitates the welding and assembly of the circuit board and the tantalum capacitor. However, the following technical problems still exist: (1) Tantalum capacitor core separation method: How to separate the capacitor core from the process strip to become an independent tantalum core; (2) Tantalum capacitor core transfer method: The tantalum core transfer process of transferring the independent tantalum core to the lead body PCB board usually adopts a single transfer method, which is difficult to achieve batch operation and limits the production speed and large-scale application.

[0004] For tantalum capacitor welding and assembly technology using metal workpieces as leads, existing welding and assembly processes still have bottlenecks. The current mainstream method is to use a turret device to place individual tantalum capacitor cores onto the metal workpieces one by one. The process involves placing the main body of the tantalum capacitor core on the negative electrode area of ​​the workpiece coated with silver paste, while simultaneously placing the tantalum wires on the capacitor core onto the positive electrode welding area of ​​the workpiece. The tantalum wires are then welded one by one to the positive electrode welding area using individual welding heads. However, this tantalum capacitor welding and assembly technology still has technical bottlenecks: because the operation of the tantalum capacitor cores is performed one by one, the welding and assembly speed of the tantalum capacitors and metal workpieces is greatly limited, making it difficult to achieve breakthroughs in higher speeds. This greatly restricts the large-scale market demand for tantalum capacitor assemblies and directly reduces the manufacturing efficiency and economic benefits of tantalum capacitor assemblies.

[0005] With the tantalum capacitor manufacturing industry continuously improving its efficiency, reducing costs, and meeting increasing demands, optimizing the assembly and welding technology of tantalum capacitor cores and components to be soldered (such as the two types of leads mentioned above) has become a focus of industry attention. Improving the assembly and welding speed of tantalum capacitor cores and components to be soldered (such as the two types of leads mentioned above) can not only reduce the manufacturing cost of tantalum capacitor assemblies but also increase their production efficiency to meet the large-scale market demand. Therefore, a new technical solution is urgently needed to partially or completely solve the technical problems of separating, transferring, and welding tantalum capacitor cores from the process strip, thereby improving the assembly and welding speed of tantalum capacitor cores and components to be soldered.

[0060] Tantalum capacitor and workpiece welding production line

[0061] like Figures 1 to 12 As shown, a tantalum capacitor welding production line to a workpiece includes:

[0062] Acquire workstations and acquire multiple tantalum capacitor cores with tantalum wires;

[0063] A conveying station that conveys multiple tantalum capacitor cores with tantalum wires to place their respective tantalum wires on a workpiece to be soldered; or, conveys multiple pre-assembled tantalum capacitor cores to a workpiece to be soldered, wherein the pre-assembled capacitor core includes: a tantalum capacitor core with tantalum wires and a pad, the pad being connected to the tantalum wires of the tantalum capacitor core.

[0064] The welding station is used to weld tantalum wires to multiple tantalum capacitor cores and the workpieces to be welded; or, to weld multiple pre-assembled tantalum capacitor cores and the workpieces to be welded.

[0065] In some embodiments, the conveying station may be equipped with an adsorption mechanism, which includes a vacuum adsorption unit and a robotic arm. The robotic arm may be a multi-axis robotic arm, with multiple vacuum suction cups (the number of vacuum suction cups may correspond to the number of tantalum capacitor cores, for example, 1-100) mounted at its end. Multiple tantalum capacitor cores or multiple pre-assembled tantalum capacitor cores are adsorbed by negative pressure. The vacuum suction cups may employ a micro-hole design to ensure uniform adsorption force. The robotic arm, controlled by a servo motor, can align the tantalum capacitor cores with tantalum wires or multiple pre-assembled tantalum capacitor cores to predetermined mounting positions on the workpiece to be soldered. The predetermined mounting positions may include positive and negative electrode areas.

[0066] In some embodiments, a conveyor belt can be used to transport the workpiece 200 to be welded. The workpiece 200 includes or is a lead frame. The lead frame includes a workpiece body 201 and a bent portion 202. The bent portion 202 is inverted L-shaped and includes a vertical portion and a flat portion. A tantalum wire contacts the bent portion 202. More specifically, the tantalum wire contacts the flat portion of the bent portion 202, and the tantalum wire is welded to the flat portion of the bent portion 202.

[0067] In some embodiments, multiple bends 202 are provided, and the multiple bends 202 are arranged along the length direction of the workpiece to be welded, or the multiple bends are arranged along both the length and width directions of the workpiece to be welded, that is, the layout of the multiple bends 202 is formed in a matrix. The length of the workpiece to be welded 200 (as the length direction of the workpiece to be welded) is greater than the width of the workpiece to be welded 200 (as the width direction of the workpiece to be welded).

[0068] In some embodiments, the lead frame may include multiple predetermined mounting positions. The robotic arm can place multiple tantalum capacitor cores with tantalum wires onto the lead frame at one time, for example, at multiple predetermined mounting positions on the lead frame. The predetermined mounting positions may include a positive electrode region and a negative electrode region. The tantalum capacitor cores are placed in the negative electrode region 204, and the tantalum wires are placed in the positive electrode region 203. The positive electrode region 203 is formed on the bending portion 202. More specifically, the positive electrode region 203 is formed on the planar portion of the bending portion 202. Multiple tantalum capacitor cores with tantalum wires are transported so that their respective tantalum wires are placed on the positive electrode region 203 of the lead frame.

[0069] In some embodiments, after a plurality of tantalum capacitor cores with tantalum wires have completed one placement of the lead frame, the lead frame carrying the plurality of capacitor cores with tantalum wires can be continuously moved by a conveyor belt. The conveyor belt moves the lead frame to the welding station, while the next set of lead frames enters the conveying station.

[0070] In some embodiments, the workpiece 200 to be soldered includes one or more pads. The workpiece 200 to be soldered can be transported using a conveying device such as a turntable. The tantalum wire of each tantalum capacitor core is placed on the pad. More specifically, the tantalum wire contacts the planar portion of the pad and is soldered to the planar portion of the pad.

[0071] In some embodiments, the welding station may be equipped with a laser welding device or a common resistance welding device. The laser welding device can generate multiple laser beams (the number of laser beams can correspond to the number of tantalum capacitor cores, for example, 1-100), and weld the tantalum wires of multiple tantalum capacitor cores to the positive electrode area of ​​the lead frame at one time, or weld the tantalum wires of multiple tantalum capacitor cores to multiple pads at one time (see invention patent application CN115722845A).

[0072] In some embodiments, such as Figure 10 , Figure 11 As shown, the pre-assembled capacitor core includes: a tantalum capacitor core 102 with tantalum wire 103 and a pad 104 (the same pad described in patent application CN115722845A). The pad 104 connects to the tantalum wire 103 of the tantalum capacitor core 102. The pre-assembled capacitor core can be the welded tantalum capacitor core as described in patent application CN115722845A. The assembly method of the pre-assembled capacitor core can refer to the welding assembly method of tantalum capacitor core and pad in the tantalum capacitor core assembly and welding production line of patent application CN115722845A to form the pre-assembled capacitor core. Specifically, the pad feeding station, tantalum capacitor core feeding station, welding station, and welded tantalum capacitor core unloading station can be arranged sequentially. Each station is connected by a conveying device, and the conveying device is equipped with a welding fixture plate 9. The welding fixture plate has a gasket positioning groove for inserting gaskets and a tantalum capacitor core positioning groove for inserting tantalum capacitor cores. After the loading station obtains multiple tantalum capacitor cores with tantalum wires, the gaskets and tantalum capacitor cores can be placed into the gasket positioning groove and the tantalum capacitor core positioning groove respectively. The tantalum wires of the tantalum capacitor cores are pressed onto the gaskets. After the loading is completed, the welding fixture plate is transferred to the welding station by a conveying device. The welding device at the welding station is equipped with a welding head. The welding head is used to weld the tantalum wires of the tantalum capacitor cores and the gaskets together at high temperature to form a welded tantalum capacitor core (i.e., a pre-assembled capacitor core). After welding, the welding fixture plate is transferred to the conveying station by a conveying device. These pre-assembled capacitor cores and the welding assembly method of the tantalum capacitor cores and gaskets are existing technologies. Accordingly, multiple pre-assembled tantalum capacitor cores are transferred to the conveying station.

[0073] In some embodiments, the workpiece 200 to be soldered includes a circuit board or a circuit board contact pad. Multiple pre-assembled tantalum capacitor cores and the workpiece to be soldered (e.g., the circuit board) are soldered. The soldering station can be equipped with a reflow soldering device. The circuit board turntable described in patent application CN115722845A can be used. Along the circumference of the circuit board turntable, a circuit board loading station, a solder paste printing station, a post-soldering tantalum capacitor core loading station (which can be used as the conveying station in this patent application), and a circuit board unloading station are arranged sequentially. The solder paste printing station is equipped with a printing head for printing solder paste onto the capacitor soldering positions on the circuit board. The post-soldering tantalum capacitor core loading station is equipped with the aforementioned adsorption mechanism for transferring the pre-assembled tantalum capacitor cores to the post-soldering tantalum capacitor core loading station. At the circuit board unloading station, a circuit board with pre-assembled tantalum capacitor cores attached is removed from the circuit board turntable and sent to the reflow soldering device for soldering, thereby completing the soldering of the pre-assembled capacitor cores and the circuit board.

[0074] In this utility model application, the workpiece to be welded supports continuous flow conveying operation. The conveying station can transport and place multiple tantalum capacitor cores at one time. The welding station can weld multiple tantalum capacitor cores with tantalum wires or multiple pre-assembled tantalum capacitor cores onto the workpiece to be welded at one time. Multiple tantalum capacitor cores can be separated from the process strip, transferred and welded to the workpiece to be welded (e.g., lead frame, multiple pads, circuit board), which greatly shortens the welding production cycle of tantalum capacitors and workpieces to be welded and improves the manufacturing efficiency and economic benefits of tantalum capacitor assemblies.

[0075] Optionally, the tantalum capacitor and soldering production line also includes:

[0076] The first loading station loads the process strips.

[0077] The process strip includes multiple tantalum capacitor cores and a carrier, with tantalum wires connecting the multiple tantalum capacitor cores to the carrier;

[0078] The positioning station is used to position multiple tantalum capacitor cores on the process strip;

[0079] The workstation is obtained, and multiple tantalum capacitor cores and carriers are separated and positioned to obtain multiple tantalum capacitor cores with tantalum wires.

[0080] In some embodiments, the process strip 100 includes a plurality of tantalum capacitor cores 102 and a carrier 101. The tantalum wires 103 of the plurality of tantalum capacitor cores are connected to the carrier 101. The carrier 101 can be a stainless steel strip or a strip of other materials. The carrier 101 is used to mount a plurality of tantalum capacitor cores 102 with tantalum wires 103.

[0081] In some embodiments, the first loading station is provided with a loading mechanism, which may include a robot and a conveyor belt, to take out the process strip 100 from the process strip hopper and place it on the conveyor belt.

[0082] In some embodiments, the positioning station may include a positioning mechanism, which can be designed according to the shape and size of the process strip 100 and the tantalum capacitor core 102. The positioning mechanism may include a process strip mounting platform and a positioning unit. The positioning unit may be mounted on the process strip mounting platform. The positioning unit may include a vacuum adsorption mechanism, which can adsorb the process strip 100 onto the process strip mounting platform.

[0083] In some embodiments, a cutting mechanism may be provided at the acquisition station. The cutting mechanism may be a laser cutting mechanism or a cutting blade mechanism. After the positioning of multiple tantalum capacitor cores on the process strip is completed, the laser cutting mechanism or the cutting blade mechanism can cut and separate the tantalum capacitor core 102 from the carrier 101. After the tantalum capacitor core 102 is separated, the tantalum capacitor core 102 with tantalum wire 103 is transferred to the conveying station, and the carrier 101 can be recycled.

[0084] Optionally, the positioning station includes a position correction mechanism, which includes multiple positioning slots and multiple first pressure heads. The positioning slots correct the tantalum capacitor core, and the first pressure heads press the corrected tantalum capacitor core into the positioning slots.

[0085] In some embodiments, the positioning groove is a V-groove, etc., and the angle (e.g., 60°-120°, preferably 90°) and depth of the V-groove are optimized according to the size and shape of the tantalum capacitor core 102. The positioning grooves are arranged in a one-dimensional or two-dimensional matrix on the process strip mounting platform, and the number of positioning grooves matches the number of tantalum capacitor cores 102 on the process strip 100 (e.g., 1-100), which can realize the simultaneous correction of multiple tantalum capacitor cores.

[0086] In some embodiments, the positioning groove is used to correct the position of the tantalum capacitor core 102, ensuring that the position and orientation of the tantalum capacitor core on the process strip 100 meet the requirements. The positioning groove can be of other shapes, and its shape and size can be customized according to the specific specifications of the tantalum capacitor core 102 to meet the needs of different product models. Those skilled in the art do not place any particular limitations on this. Any positioning groove that can correct each tantalum capacitor core falls within the scope of protection of this utility model application.

[0087] In some embodiments, after the tantalum capacitor core has been calibrated, to prevent displacement in subsequent processes, multiple first pressure heads can be driven by cylinders to apply uniform clamping force (e.g., 0.5-10N), suitable for rapid batch operations. Each first pressure head can correspond to a positioning groove, and the bottom shape of the first pressure head matches the top of the tantalum capacitor core 102 (e.g., a plane) to ensure uniform contact. The first pressure heads support independent or group control, and a controller (e.g., a common PLC or microprocessor MCU) can be used in independent or group control, allowing multiple tantalum capacitor cores to be clamped simultaneously by applying clamping force through multiple first pressure heads. After the first pressure heads clamp and calibrate the tantalum capacitor cores in the positioning grooves, the positioning of multiple tantalum capacitor cores on the process strip is completed.

[0088] Optionally, the acquisition station includes a cutting mechanism that cuts off multiple tantalum capacitor cores and carriers after separation and positioning.

[0089] In some embodiments, the cutting mechanism includes a cutter, which may be made of a blade of high-hardness alloy steel (such as tungsten steel) suitable for cutting tantalum wires 103. The blade may be designed as a straight line, an arc, or a custom shape. The cutter may cut multiple tantalum wires 103 at once to obtain multiple tantalum capacitor cores with tantalum wires.

[0090] In some embodiments, a cylinder can be used to push the cutter downwards to apply a uniform cutting force. Before cutting, the process strip 100 is fixed to the worktable of the acquisition station by a vacuum adsorption platform or fixture to prevent movement. After the tantalum capacitor core 102 is positioned by correcting the positions of multiple tantalum capacitor cores at the positioning station and being pressed by multiple first pressure heads, the cutter needs to be aligned with one side of the tantalum wire 103, which is close to the connection point between the tantalum wire 103 and the carrier 101. The cutter does not cause cutting damage to the carrier 101 during cutting, and multiple or all of the tantalum wires 103 can be cut at once. After the cutting and separation are completed, the tantalum capacitor core 102 is separated from the carrier 101. The tantalum capacitor core 102 retains most of the tantalum wires 103 before separation, thereby obtaining multiple tantalum capacitor cores 102 with tantalum wires.

[0091] Optionally, the tantalum capacitor and soldering production line also includes:

[0092] The first unloading station unloads the separated carrier.

[0093] In some embodiments, after the tantalum capacitor core 102 and the carrier 101 are separated at the acquisition station, the carrier 101 with a small portion of tantalum wire can be gripped or sucked up by a clamp with a robotic arm or a vacuum suction cup, and the carrier 101 with a small portion of tantalum wire can be placed in a collection box or recycling box.

[0094] Optionally, the conveying station includes an adsorption mechanism that adsorbs multiple tantalum capacitor cores with tantalum wires; and / or a displacement adsorption mechanism that adsorbs multiple tantalum capacitor cores with tantalum wires and changes the position of at least some of the tantalum capacitor cores with tantalum wires to correspond to the position of the workpiece to be welded.

[0095] In some embodiments, the adsorption mechanism 300 includes multiple vacuum suction cups S, such as a 1×100 array (100 suction cups in total) or a 10×10 array (100 suction cups in total), which can simultaneously adsorb 100 cores. The vacuum suction cups can generate negative pressure through a vacuum pump.

The robotic arm moves the adsorption mechanism above the acquisition station, aligns it with multiple tantalum capacitor cores with tantalum wires, the vacuum pump is started, the robotic arm moves down, and the vacuum suction cups adsorb multiple tantalum capacitor cores with tantalum wires through the negative pressure. The robotic arm transfers the adsorbed multiple tantalum capacitor cores 102 with tantalum wires to correspond to the position of the workpiece to be welded. The tantalum wires of each of the multiple tantalum capacitor cores 102 correspond to the predetermined installation positions of the tantalum wires on the workpiece to be welded, and the tantalum wires of the multiple tantalum capacitor cores with tantalum wires are placed on the workpiece to be welded.

[0098] In some embodiments, the suction cup rotation mechanism can be motor-driven, with the motor driving the vacuum suction cup to rotate within a rotation angle range of 0° to 360°. The suction cup lateral and longitudinal translation mechanism adjusts the lateral position (e.g., X-axis) and / or longitudinal position (e.g., Y-axis) of the vacuum suction cup to match the spacing and layout of the mounting positions on the workpiece to be welded. The suction cup lateral and longitudinal translation mechanism can employ a linear guide and slider system, driven by a servo motor or linear motor, providing high-precision translation (accuracy ±0.01mm).

An adsorption mechanism or a displacement adsorption mechanism adsorbs multiple tantalum capacitor cores with tantalum wires and places them in the positioning groove (it should be noted that the displacement adsorption mechanism adsorbs multiple tantalum capacitor cores with tantalum wires and can change the position of at least some of the tantalum capacitor cores with tantalum wires to correspond to the positioning groove). Multiple pushers can be pneumatically or electrically driven, and each pusher pushes the tantalum capacitor core with tantalum wires placed at the entrance of the three-sided positioning groove into the bottom of the positioning groove. The three-sided positioning groove with V-shaped openings positions the tantalum capacitor core with tantalum wires. The suction head mechanism includes multiple suction heads, and the multiple suction heads can form a suction head array. The multiple suction heads pick up the multiple tantalum capacitor cores with tantalum wires positioned in the positioning template and place their respective tantalum wires on the workpiece to be welded. For example, the suction head can be a suction nozzle, and the push head can be a push block. The workpiece to be soldered is a lead frame or multiple pads. For the lead frame, multiple suction heads pick up multiple tantalum capacitor cores with tantalum wires positioned in the positioning template, and place the tantalum capacitor cores in the negative terminal area and the tantalum wires in the positive terminal area.

(It should be noted that the displacement adsorption mechanism adsorbs multiple tantalum capacitor cores with tantalum wires and can change the position of at least some of the tantalum capacitor cores with tantalum wires to correspond with the positioning part.) Multiple pushers can be pneumatically or electrically driven. Each pusher pushes a tantalum capacitor core with tantalum wires placed near the positioning part towards its two right-angled sides, which position the tantalum capacitor core with tantalum wires. The suction head mechanism includes multiple suction heads, which can form a suction head array. The multiple suction heads pick up the multiple tantalum capacitor cores with tantalum wires positioned in the positioning template and place their respective tantalum wires onto the workpiece to be welded. Specifically, the suction head can be a nozzle, and the pusher can be a pusher block. The workpiece to be soldered is a lead frame or multiple pads.

The pre-assembled capacitor core can be the welded tantalum capacitor core in patent application CN115722845A. The assembly method of the pre-assembled capacitor core can refer to the welding assembly method of tantalum capacitor core and pad in the tantalum capacitor core assembly and welding production line in patent application CN115722845A to form the pre-assembled capacitor core. Specifically, it may include a pad feeding station, a tantalum capacitor core feeding station, a welding station, and a welded tantalum capacitor core unloading station arranged sequentially. Each station is connected by a conveying device. The conveying device is provided with a welding fixture plate 9, and the welding fixture plate has a pad positioning groove for inserting the pad. The process involves a tantalum capacitor core positioning groove for inserting tantalum capacitor cores. After multiple tantalum capacitor cores with tantalum wires are obtained at the receiving station, the spacer and the tantalum capacitor core can be placed into the spacer positioning groove and the tantalum capacitor core positioning groove, respectively. The tantalum wire of the tantalum capacitor core is pressed onto the spacer. After the material loading is completed, the welding fixture plate is transferred to the welding station by the conveying device. The welding device at the welding station is equipped with a welding head. The welding head is used to weld the tantalum wire of the tantalum capacitor core and the spacer together at high temperature to form a welded tantalum capacitor core (i.e., a pre-assembled capacitor core). After welding, the welding fixture plate is transferred to the conveying station by the conveying device. The welding assembly method of these pre-assembled capacitor cores and the tantalum capacitor core and spacer is existing technology. Accordingly, multiple pre-assembled tantalum capacitor cores are transferred to the conveying station, and the conveying station can then transport multiple pre-assembled tantalum capacitor cores to the workpiece to be welded.

[0195] In the working method of the tantalum capacitor and soldering workpiece production line of this utility model application, firstly, the tantalum capacitor and soldering workpiece welding production line completes the process of obtaining (separating) and transferring multiple tantalum capacitor cores with tantalum wires to the welding process. Step S100 can obtain (separate) multiple tantalum capacitor cores with tantalum wires at one time. Step S200 can use an adsorption or displacement adsorption mechanism to realize the transfer of multiple tantalum capacitor cores with tantalum wires or multiple pre-assembled tantalum capacitor cores. Step S300 realizes the connection between multiple tantalum capacitor cores with tantalum wires and the soldering workpiece (e.g., lead frame, multiple pads) through laser / resistance welding, or realizes the connection between multiple pre-assembled tantalum capacitor cores and the soldering workpiece (e.g., lead frame, multiple pads) through reflow soldering. The connection of tantalum capacitors (such as circuit boards) allows for seamless integration of the entire process, making it suitable for mass production. Steps S100, S200, and S201 can be operated continuously in a production line, optimizing the welding and assembly speed of tantalum capacitors and components to be soldered, and improving the manufacturing efficiency and economic benefits of tantalum capacitor assemblies. In addition, step S200 can utilize a displacement adsorption mechanism (including translation and rotation functions) to accurately place the tantalum capacitor core of the tantalum wire in the positive and negative electrode areas of the component to be soldered (lead frame), supporting the processing of tantalum capacitor cores of different quantities and sizes. The stainless steel strip carrier separated in step S100 can be recycled and reused, reducing material waste and lowering the production cost of tantalum capacitor assembly manufacturing.
