Technical Field
[0001] This utility model relates to the field of activation device technology, and in particular to a vacuum-assisted double-buffered activation device. Background Technology
[0002] The vacuum-assisted dual-buffered activation device creates a vacuum environment to reduce interference from external gases during the activation process. At the same time, it utilizes a dual-buffered structure to precisely control pressure changes during the activation process. Under vacuum conditions, the target substance can receive activation stimulation in a purer environment. The dual buffering effectively avoids the impact of sudden pressure changes on the substance's structure and reaction process, further optimizing the activation effect and improving the stability and consistency of product quality.
[0003] A search revealed Chinese patent publication number CN216550227U, which discloses an activation device. This activation device includes at least: a pressing body; and multiple movable pressure heads connected side-by-side to the same side of the pressing body, each capable of moving relative to the pressing body, used to press a first adhesive object to activate the adhesive between the first and second adhesive objects. The movable pressure heads move in a direction perpendicular to the plane of the adhesive. This disclosed embodiment uses a split-type pressing method, capable of pressing the first adhesive object using multiple movable pressure heads. However, in actual use, when the power supply device contacts the VFD board, it can cause deformation of the VFD board's pins, affecting subsequent spot welding processes and thus impacting yield. Utility Model Content
[0004] To overcome the above deficiencies, this utility model provides a vacuum-assisted dual-buffered activation device, which aims to improve the problem in the prior art where the pins of the VFD board deform when the energized device comes into contact with the VFD board.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a vacuum-assisted double-buffered activation device, comprising a frame, an activation mechanism at the top of the frame, a guide mechanism at the bottom of the activation mechanism for limiting the movement range of the activation mechanism, a lifting mechanism at the bottom of the frame, a drive mechanism at the front of the lifting mechanism for driving the device to operate, and a fixing mechanism on the right side of the frame.
[0006] The activation mechanism includes two support members. The bottoms of the two support members are slidably connected to the front and rear sides of the top of the frame, respectively. An energized moving rod is fixedly connected to the inner wall of the two support members. An L-shaped plate is fixedly connected to the opposite side of the two support members. A sliding rod is slidably connected to the inner wall of the two L-shaped plates. A fixing block three is fixedly connected to the right end of the two sliding rods. A spring one is slidably connected to the outer wall of the two sliding rods. A spring two is fixedly connected to the right end of the two energized moving rods. A contact pin is slidably connected to the inner wall of the two energized moving rods. A VFD plate is provided on the right side of the frame. Pin one is fixedly connected to the front and rear ends of the left side of the two VFD plates.
[0007] Through the above technical solution: the support component slides on the front and rear sides of the top of the frame. The movement of the support component drives the energized moving rod to approach the VFD board. During this process, the sliding rod slides inside the L-shaped plate and compresses the first spring. The first spring provides the first layer of buffer, slowing down the movement speed of the support component and reducing the impact force on the VFD board. At the same time, the contact pin slides inside the energized moving rod and compresses the second spring. The second spring provides the second layer of buffer. Finally, the contact pin is in contact with the first pin of the VFD board, the energized moving rod is energized, and the VFD board is activated. The double buffer effectively prevents the first pin from being deformed due to collision, ensuring the activation effect.
[0008] As a further description of the above technical solution:
[0009] The lifting mechanism includes two lifting columns. The tops of the two lifting columns are fixedly connected to the bottom left and right sides of the frame platform, respectively. The front sides of the two lifting columns are fixedly connected to toothed plates. The outer walls of the two lifting columns are slidably connected to support legs two. The bottoms of the two support legs two are fixedly connected to the same base plate.
[0010] With the above technical solution, two lifting columns are located on the left and right sides of the bottom of the frame platform respectively, and move synchronously, so that the frame platform can be raised and lowered smoothly. The second support leg plays a guiding role to ensure that the lifting columns move vertically, while the base plate firmly supports the entire device. In this way, the height of the frame platform can be flexibly adjusted according to different work requirements to adapt to various operating scenarios.
[0011] As a further description of the above technical solution:
[0012] The fixing mechanism includes multiple support legs, the bottom of which is fixedly connected to the top right side of the base plate. The top of each support leg is fixedly connected to the same worktable. The top of the worktable is slidably connected to the bottom of the pin. The top of the worktable has a groove. The inner wall of the groove is slidably connected to sliders on both the front and back sides. The top of each slider is fixedly connected to a clamping plate. The adjacent side of each clamping plate is fixedly connected to a clamping pad. A rotating assembly is provided inside the worktable.
[0013] The above technical solution involves placing the VFD plate on the worktable and rotating the bidirectional lead screw. Because the threads on the front and rear sides of the lead screw are connected to the threads on the inner walls of the corresponding sliders, the two sliders will move towards and away from each other along the slide groove. The sliders drive the clamping plates at the top to move synchronously. When the clamping plates move towards each other, the clamping pads gradually approach the sides of the VFD plate. Finally, the clamping pads contact the VFD plate and apply pressure, using friction to firmly fix the VFD plate on the worktable, ensuring the stability of the VFD plate in subsequent operations.
[0014] As a further description of the above technical solution:
[0015] The drive mechanism includes a servo motor, the bottom of which is fixedly connected to the top right side of the frame. The output end of the servo motor is fixedly connected to a rotating shaft. Both the left and right sides of the outer wall of the rotating shaft are fixedly connected to drive gears. A stabilizing column is rotatably connected to the left side of the outer wall of the rotating shaft. The bottom of the stabilizing column is fixedly connected to the top of the frame. Cylinders are fixedly connected to the front and rear sides of the top of the frame. The right ends of the two cylinders are respectively fixedly connected to the left side of the corresponding support.
[0016] Through the above technical solution: when the servo motor is powered on, its output end drives the rotating shaft to rotate, and the active gears on both sides of the rotating shaft rotate accordingly. They can cooperate with the gear plate of the lifting mechanism to drive the frame platform to rise and fall. The stabilizing column ensures the stability of the rotating shaft when it rotates. At the same time, the cylinder on the top of the frame platform is activated. When the cylinder extends, it pushes the support to move to the left, and when it retracts, it pulls the support back, thereby adjusting the position of the activation mechanism and providing power and position adjustment for the activation operation.
[0017] As a further description of the above technical solution:
[0018] The guiding mechanism includes multiple fixed blocks 1, the bottom of each fixed block 1 is fixedly connected to the top of the machine frame, the inner wall of each fixed block 1 is fixedly connected to a guide rod, the outer wall of each guide rod is slidably connected to the inner wall of the corresponding support member, the right side of the outer wall of each guide rod is fixedly connected to a fixed block 2, and the bottom of each fixed block 2 is fixedly connected to the top right side of the machine frame.
[0019] Through the above technical solution: the inner wall of the support component slides along the outer wall of the guide rod, the first fixing block stabilizes the guide rod on the top of the frame and provides support for the guide rod, the second fixing block further fixes the right side of the guide rod to prevent it from shaking, the guide rod limits the support component to move only along its axial direction, ensuring the precise movement path of the support component, thereby ensuring the smooth operation of the activation mechanism and improving the accuracy of the activation operation.
[0020] As a further description of the above technical solution:
[0021] The rotating assembly includes a bidirectional lead screw, the outer wall of which is threaded to the inner wall of the corresponding slider on its front and rear sides respectively. A turntable is fixedly connected to the front end of the bidirectional lead screw, and a handle is rotatably connected to the top front side of the turntable.
[0022] Through the above technical solution: the operator turns the handle, which drives the turntable to rotate, thereby causing the bidirectional lead screw to rotate. Since the front and rear threads of the bidirectional lead screw are opposite and are connected to the inner wall of the corresponding slider, the rotation will drive the two sliders to move towards and away from each other along the slide groove, thereby causing the clamping plate to move closer and further away, realizing the clamping and releasing action of the VFD plate.
[0023] As a further description of the above technical solution:
[0024] Limiting blocks are fixedly connected to the front and rear sides of the inner wall of the slide. Buffer pads are fixedly connected to adjacent sides of the two limiting blocks, and one side of each buffer pad is in contact with the other side of the corresponding slider.
[0025] Through the above technical solution: when the slider approaches the two ends of the slide, it will contact the buffer pad. The limiting block is fixed to the inner wall of the slide, limiting the movement range of the slider and preventing the slider from falling out of the slide. The buffer pad uses its own elasticity to buffer the impact force at the moment the slider contacts the limiting block, protecting the slider and the slide and ensuring the stable operation of the fixing mechanism.
[0026] As a further description of the above technical solution:
[0027] The left ends of both slide rods are fixedly connected to limit blocks two, and the right sides of the two limit blocks two are respectively attached to the left side of the corresponding L-shaped plate.
[0028] The above technical solution prevents the slide bar from sliding out of the L-shaped plate, ensures that the spring can play a normal buffering role, and maintains the stable operation of the activation mechanism.
[0029] This utility model has the following beneficial effects:
[0030] 1. In this utility model, when the device is running, the drive mechanism is started, the servo motor drives the rotating shaft to rotate, and the active gear and the toothed plate cooperate to drive the lifting mechanism, so that the frame platform is raised and lowered under the guidance of the support legs and the lifting column. At the same time, the cylinder pushes the support component to slide along the guide rod of the guide mechanism. The movement of the support component drives the energized moving rod to approach the VFD board. During the process, the slide rod compression spring provides the first layer of buffer, and the contact pin compresses the spring in the energized moving rod to provide the second layer of buffer, so as to avoid the deformation of the VFD board pin and improve the yield rate.
[0031] 2. In this utility model, when fixing the VFD plate, the operator turns the handle to drive the turntable to rotate the bidirectional lead screw. Since the front and rear threads of the bidirectional lead screw are in opposite directions, they are threadedly connected to the inner wall of the slider. When rotating, the slider moves towards and away from each other along the slide groove, which drives the top clamping plate to move. When moving towards each other, the distance between the clamping plates decreases, and the clamping pads contact both sides of the VFD plate and apply pressure to firmly clamp it, which not only prevents slippage but also avoids damage, ensuring the stability of the VFD plate during activation and improving the activation effect and yield.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0040] Reference Figure 2 , Figure 3 and Figure 5 This utility model provides an embodiment of a vacuum-assisted double-buffered activation device, including a frame 1, which provides an installation and support platform. An activation mechanism 2 is provided on the top of the frame 1, which is responsible for activating the VFD plate 209. A guide mechanism 6 is provided at the bottom of the activation mechanism 2, which limits the movement range of the activation mechanism 2 and ensures that the activation mechanism 2 moves on a predetermined path, thereby improving the accuracy of the operation. A lifting mechanism 4 is provided at the bottom of the frame 1, which can adjust the height of the frame 1 to adapt to different work requirements. A drive mechanism 5 is provided on the front side of the lifting mechanism 4, which is used to drive the device and provide a power source for the movement of each part of the device. A fixing mechanism 3 is provided on the right side of the frame 1, which is used to securely place and fix the VFD plate 209, ensuring that the position of the VFD plate 209 is stable during the activation process.
[0041] The activation mechanism 2 includes two support members 201, which provide support and connection points for other components of the activation mechanism 2. The bottoms of the two support members 201 are slidably connected to the front and rear sides of the top of the frame 1, respectively, allowing the support members 201 to move on the frame 1 and thus adjust the position of the activation mechanism 2. An energized moving rod 202 is fixedly connected to the inner wall of the two support members 201. The energized moving rod 202 is used to connect to the power supply and move the contact pin 208 closer to and further away from the VFD board 209. An L-shaped plate 203 is fixedly connected to the opposite side of each of the two support members 201. The L-shaped plate 203 provides mounting positions for the slide rod 204 and the spring 205. The inner wall of the L-shaped plate 203 is slidably connected with sliding rods 204. The sliding rods 204 slide within the L-shaped plate 203 and cooperate with spring 205 to provide a buffering effect. The right ends of the two sliding rods 204 are fixedly connected with fixing blocks 206. Fixing blocks 206 are used to fix the right end position of the sliding rods 204 to ensure that the sliding rods 204 slide within a specified range. The outer walls of the two sliding rods 204 are slidably connected with springs 205. Springs 205 provide the first layer of buffering to reduce the speed and impact force when the support 201 moves. The left ends of the two springs 205 are fixedly connected to the right side of the corresponding L-shaped plate 203 to ensure that the connection between the springs 205 and the L-shaped plate 203 is stable.
[0042] The right ends of the two springs 205 are respectively fixedly connected to the left side of the corresponding fixed block 206, so that the springs 205 have a stable support point on the slide bar 204. The bottom of the two fixed blocks 206 are fixedly connected to the top of the frame 1, further fixing the position of the slide bar 204 and the springs 205. The right ends of the two energized moving rods 202 are fixedly connected to the springs 207, which provide a second layer of buffer to reduce the impact force when the contact pin 208 contacts the pin 210 of the VFD board 209. The inner walls of the two energized moving rods 202 are slidably connected to the contact pins 208, which are used to contact the VFD board. Pin 210 of 209 contacts the contact pin to transmit the current required for activation. The outer walls of the two contact pins 208 are slidably connected to the inner walls of the corresponding springs 207 to ensure that the springs 207 can effectively buffer the movement of the contact pins 208. A VFD board 209 is set on the right side of the frame 1. The VFD board 209 is the object of the activation operation. Pin 210 is fixedly connected to the front and rear ends of the left side of the two VFD boards 209. Pin 210 is used to contact the contact pins 208 to receive the activation current. The left sides of the two pins 210 are respectively attached to the right sides of the corresponding contact pins 208 to realize electrical connection to activate the VFD board 209.
[0043] The lifting mechanism 4 includes two lifting columns 401, which provide guidance and support for the lifting of the frame platform 1. The tops of the two lifting columns 401 are fixedly connected to the bottom left and right sides of the frame platform 1, respectively, to ensure a stable connection between the frame platform 1 and the lifting columns 401. The front sides of the two lifting columns 401 are fixedly connected to toothed plates 402, which cooperate with the drive gear 503 in the drive mechanism 5 to realize the lifting movement of the frame platform 1. The outer walls of the two lifting columns 401 are slidably connected to support legs 403, which support the frame platform 1 and slide on the lifting columns 401 to ensure that the lifting of the frame platform 1 is stable. The bottoms of the two support legs 403 are fixedly connected to the same base plate 404, which provides a stable foundation for the entire device.
[0044] The drive mechanism 5 includes a servo motor 501, which serves as the power source for the drive mechanism 5, providing power for the operation of the drive device. The bottom of the servo motor 501 is fixedly connected to the top right side of the frame 1 to ensure stable installation. A rotating shaft 502 is fixedly connected to the output end of the servo motor 501, which transmits the power of the servo motor 501 to the drive gear 503. Drive gears 503 are fixedly connected to both the left and right sides of the outer wall of the rotating shaft 502. The drive gears 503 mesh with the gear plate 402, driving the lifting mechanism 4 to work and realize the lifting and lowering of the frame 1. A stabilizing column 504 is rotatably connected to the left side of the outer wall of the shaft 502. The stabilizing column 504 enhances the stability of the shaft 502 when it rotates. The bottom of the stabilizing column 504 is fixedly connected to the top of the frame 1 to ensure stable support of the shaft 502. Cylinders 505 are fixedly connected to the front and rear sides of the top of the frame 1. The cylinders 505 provide power for the movement of the support member 201, pushing the activation mechanism 2 to move closer to and away from the VFD plate 209. The right ends of the two cylinders 505 are fixedly connected to the left side of the corresponding support member 201 to ensure that the cylinders 505 can effectively drive the support member 201 to move.
[0045] The guiding mechanism 6 includes multiple fixing blocks 601, which are used to fix the position of the guide rods 602. The bottom of each fixing block 601 is fixedly connected to the top of the frame 1 to ensure a stable connection between the fixing blocks 601 and the frame 1. The inner walls of each fixing block 601 are fixedly connected to the guide rods 602, which provide guidance for the movement of the support member 201, allowing it to move in a predetermined direction. The outer walls of each guide rod 602 are slidably connected to the inner walls of the corresponding support members 201 to ensure that the support members 201 slide smoothly on the guide rods 602. The right side of the outer walls of each guide rod 602 is fixedly connected to a fixing block 603, which further fixes the right end of the guide rod 602 to enhance its stability. The bottom of each fixing block 603 is fixedly connected to the top right side of the frame 1 to ensure a firm connection between the fixing block 603 and the frame 1.
[0046] Specifically, when drive mechanism 5 is activated, servo motor 501 drives rotating shaft 502 to rotate. Drive gear 503 mounted on rotating shaft 502 rotates accordingly, cooperating with gear plate 402 to drive lifting mechanism 4. This allows the frame platform 1 to rise and fall under the guidance of support leg 2 403 and lifting column 401, meeting different height requirements. Simultaneously, cylinder 505, as the direct power source for activating mechanism 2, pushes support member 201 to slide along guide rod 602 of guide mechanism 6. Guide rod 602 is securely mounted on frame platform 1 by fixing block 1 601 and fixing block 2 603, ensuring smooth movement of support member 201 and limiting its range of motion. When support member 201 moves, it drives energized moving rod 202 closer to VFD plate 209. During this process… In the process, the slide bar 204 slides within the L-shaped plate 203, compressing the first spring 205. The first spring 205 provides the first layer of buffer, slowing down the movement speed of the support 201 and reducing the impact force on the VFD plate 209. Furthermore, the contact pin 208 slides within the energized moving rod 202 and compresses the second spring 207, which provides the second layer of buffer. This greatly reduces the impact force at the moment of contact when the contact pin 208 contacts the first pin 210 of the VFD plate 209, effectively preventing the first pin 210 from deforming. This achieves double buffering of the contact action during the activation of the VFD plate, ensuring reliable contact between the energizing device and the first pin 210 in the VFD plate 209, and preventing pin deformation, thereby improving the yield rate of subsequent spot welding processes.
[0047] Reference Figure 1 , Figure 2 and Figure 4The fixing mechanism 3 includes multiple support legs 301, which support the worktable 302 at a suitable height. The bottoms of the multiple support legs 301 are fixedly connected to the top right side of the base plate 404, securing the worktable 302 to the base plate 404. The tops of the multiple support legs 301 are all fixedly connected to the same worktable 302, which serves as a platform for placing the VFD plate 209. The top of the worktable 302 is slidably connected to the bottom of the pin 210, facilitating the adjustment of the position of the VFD plate 209 on the worktable 302. The top of the worktable 302 has a slide groove 306, which provides a sliding track for the slider 303. The slider 303 is slidably connected to the front and rear sides of the inner wall of the slide groove 306, allowing it to move within the slide groove 306 and drive the clamping plate 304 to move. The tops of the two sliders 303 are fixedly connected to the clamping plate 304, which is used to clamp the VFD plate. 209. Clamping pads 305 are fixedly connected to adjacent sides of both clamping plates 304. The clamping pads 305 increase the friction with the VFD plate 209 and prevent damage to the VFD plate 209. A rotating assembly 307 is provided inside the worktable 302. The rotating assembly 307 drives the slider 303 to move. The rotating assembly 307 includes a bidirectional lead screw 3071. When the bidirectional lead screw 3071 rotates, it causes the slider 303, which is threaded to it, to move towards and away from each other. The outer and rear sides of the lead screw 3071 are respectively threaded to the inner walls of the corresponding sliders 303 to control the movement of the sliders 303. The front end of the bidirectional lead screw 3071 is fixedly connected to a turntable 3072, which is used to transmit the rotational force of the handle 3073 to the bidirectional lead screw 3071. The handle 3073 is rotatably connected to the top front side of the turntable 3072. The operator drives the turntable 3072 and the bidirectional lead screw 3071 to rotate by rotating the handle 3073.
[0048] Specifically, the operator rotates the handle 3073, which drives the turntable 3072 to rotate, thereby causing the bidirectional lead screw 3071 to rotate. Since the front and rear threads on the outer wall of the bidirectional lead screw 3071 are in opposite directions and are respectively threaded to the inner wall of the corresponding slider 303, when the bidirectional lead screw 3071 rotates, the two sliders 303 will move towards and away from each other along the slide groove 306. As the sliders 303 move, the clamping plates 304 fixed on the top of the sliders 303 also move. When they move towards each other, the distance between the two clamping plates 304 gradually decreases, and the clamping pads 305 contact the two sides of the VFD 209 and apply pressure to firmly clamp the VFD plate 209. The clamping pads 305 can increase the friction to prevent the VFD plate 209 from sliding and avoid damage to the surface of the VFD plate 209. In this way, the VFD plate 209 can maintain a stable position during the activation process, ensuring reliable contact between the pins and the power supply device, improving the activation effect and the yield of subsequent processes.
[0049] Reference Figure 3 and Figure 4 Limiting blocks 7 are fixedly connected to the front and rear sides of the inner wall of the slide groove 306. Limiting blocks 7 restrict the movement range of the slider 303 within the slide groove 306, preventing the slider 303 from detaching from the slide groove 306. Buffer pads 8 are fixedly connected to adjacent sides of the two limiting blocks 7. The buffer pads 8 buffer the slider 303 when it contacts the limiting blocks 7, reducing the impact force and protecting the slider 303 and the limiting blocks 7 from damage. One side of each buffer pad 8 is respectively connected to the corresponding slider 303. The other side is in contact with each other to ensure that the buffer pad 8 can effectively buffer the impact force when the slider 303 moves to the limit position. The left ends of the two sliders 204 are fixedly connected to the limit block 2 9. The limit block 2 9 is used to limit the distance of the slider 204 to the left to prevent the slider 204 from sliding out of the L-shaped plate 203. The right side of the two limit blocks 2 9 is in contact with the left side of the corresponding L-shaped plate 203 to ensure that the limit block 2 9 can accurately limit the movement of the slider 204 and work together with the L-shaped plate 203.
[0050] Specifically, limit block 7 is fixed to the inner wall of slide groove 306 to limit the movement range of slider 303, buffer pad 8 reduces the impact of collision between slider 303 and limit block 7, and limit block 9 is connected to the left end of slide rod 204 to prevent L-shaped plate 203 from sliding off slide rod 204. Through these structures, the L-shaped plate 203 and slide rod 204 are ensured to move within the specified range, improving the stability and reliability of device operation and ensuring the smooth fixing and activation of VFD plate 209.
[0051] Working principle: When the device is running, the drive mechanism 5 is activated, and the servo motor 501 drives the rotating shaft 502 to rotate. The drive gear 503 mounted on the rotating shaft 502 rotates accordingly, cooperating with the gear plate 402 to drive the lifting mechanism 4 to work. This allows the frame platform 1 to be raised and lowered under the guidance of the second support leg 403 and the lifting column 401, meeting different height requirements. At the same time, the cylinder 505, as the direct power source for activating the movement of the mechanism 2, pushes the support member 201 to slide along the guide rod 602 of the guide mechanism 6. The guide rod 602 is securely mounted on the frame platform 1 by the first fixing block 601 and the second fixing block 603, ensuring that the support member 201 moves smoothly and limiting its range of movement. When the support member 201 moves, it drives the energized moving rod 202 to approach the VFD plate 209. During this process, the slide bar 204 slides within the L-shaped plate 203, compressing the first spring 205. The first spring 205 provides the first layer of buffer, slowing down the movement speed of the support 201 and reducing the impact force on the VFD plate 209. Furthermore, the contact pin 208 slides within the energized moving rod 202 and compresses the second spring 207, which provides the second layer of buffer. This greatly reduces the impact force at the moment of contact when the contact pin 208 contacts the first pin 210 of the VFD plate 209, effectively preventing the first pin 210 from deforming. This achieves double buffering of the contact action during the activation of the VFD plate, ensuring reliable contact between the energizing device and the first pin 210 in the VFD plate 209, and preventing pin deformation, thereby improving the yield rate of subsequent spot welding processes.
[0052] Furthermore, when it is necessary to fix the VFD plate 209, the operator turns the handle 3073, which drives the turntable 3072 to rotate, thereby causing the double-acting lead screw 3071 to rotate. Since the front and rear threads on the outer wall of the double-acting lead screw 3071 are in opposite directions and are respectively threaded to the inner wall of the corresponding slider 303, when the double-acting lead screw 3071 rotates, the two sliders 303 will move towards and away from each other along the slide groove 306. As the sliders 303 move, the clamping plate 304 fixed on the top of the slider 303 also... As the plates move towards each other, the distance between the two clamping plates 304 gradually decreases. The clamping pads 305 contact the sides of the VFD 209 and apply pressure to firmly clamp the VFD 209. The clamping pads 305 can increase friction to prevent the VFD 209 from sliding and avoid damage to the surface of the VFD 209. In this way, the VFD 209 can maintain a stable position during the activation process, ensuring reliable contact between the pins and the power supply device, improving the activation effect and the yield of subsequent processes.
