Description

Technical Field

[0001] This invention belongs to the technical field of electronic component mounting equipment, and in particular relates to a chip component mounting machine feeder. Background Technology

[0002] Surface Mount Technology (SMT) is a core process in the modern electronics assembly industry. Among its components, the pick-and-place machine, as a key piece of equipment, directly determines the efficiency and flexibility of the entire production line through the performance of its feeding system. Components are typically packaged and transported in reel tape. The pick-and-place machine's feeder pulls and positions the tape on the reel, peels off the surface covering film, and precisely exposes the components in predetermined positions for the pick-and-place machine's nozzles to pick them up. Therefore, an efficient, stable, and adaptable feeder is crucial for increasing placement capacity and adapting to multi-variety, small-batch production models.

[0003] While the development of feeders in existing technologies is mature, many limitations still exist. For example, Chinese patent application CN 116017968 A discloses a feeder for a pick-and-place machine to prevent material ejection. This feeder includes a housing with a tape clamping block installed inside, located below a push rod. A clamping spring is located at the lower end of the tape clamping block. The housing contains an inlet, a guide rail, and an outlet. A pick-up port is located above the guide rail and communicates with it. A groove is provided at the bottom of the housing, and a power control mechanism is installed within the groove. This feeder can automatically feed and peel off tape from surface mount components. However, it still has the following drawbacks in practical use: 1. Most existing traditional feeders can only install a single specification of tape and feed material in a fixed direction. The feeding mode is simple and lacks flexibility. When different sizes of components need to be switched on the production line, or when both sides of the PCB board need to be fed on one machine at the same time, the machine must be stopped and the feeder must be replaced and readjusted manually, which seriously affects production efficiency and cannot meet the needs of flexible manufacturing. 2. Existing feeders are usually open or fixed exposed structures. Their outlets cannot be stored, resulting in low space utilization and poor integration. When multiple feeders are installed side by side on a pick-and-place machine, they occupy a lot of valuable production line space. Unused workstations cannot be hidden, making the entire placement platform look cluttered and not conducive to the miniaturization and high-density layout of the equipment. 3. Currently, when it is necessary to adjust the tape path or replace the take-up roller, it is often necessary to manually disassemble and install multiple parts. The positioning of the separator also relies on manual calibration, which is cumbersome and prone to errors. This not only increases the labor intensity of operators, but also brings the risk of material supply failure due to human error. Summary of the Invention

[0004] The purpose of this invention is to provide a chip mounter feeder for surface mount components. By setting up a flexibly adjustable feeding mechanism, a liftable ejector seat that can be stored in a cabinet, and an automatically linked separator, it solves the problems of existing feeders having a single mode that cannot adapt to feeding multi-size components, low space utilization, and cumbersome operation and maintenance.

[0015] The present invention has the following beneficial effects: 1. This invention, by setting up a movable separator and an adjustable feeding mechanism, allows the equipment to drive the separator via a screw assembly, synchronously moving each separator plate. This enables rapid switching between single feeding channel (compatible with large and small-sized tape and reel) and dual feeding channel (suitable for two small-sized tape and reel) modes, achieving flexible switching of feeding modes and "one machine for multiple uses." At the same time, combined with the independently liftable and movable discharge seats on both sides, it can be flexibly configured for unidirectional or bidirectional feeding, perfectly adapting to the production needs of mounting various components and PCB board side layouts, greatly enhancing the adaptability and flexibility of the production line.

[0016] 2. This invention employs a highly efficient, retractable cabinet design. Two feeder trays are integrated into the cabinet, working in conjunction with a hydraulic lifting mechanism and an electric sliding door assembly. In non-working mode, the feeder trays can be lowered and stored inside the cabinet, with the electric door automatically closing, creating a compact overall appearance. During operation, they can be moved out and raised to the working position as needed. This design completely changes the traditional fixed and exposed feeder model, saving valuable longitudinal and transverse space on the production line. It enables high-density, modular mounting layouts, significantly improving equipment integration and production line space utilization.

[0017] 3. Through automated execution and linkage design, this invention enables fully automated operation of the entire process, from the removal of the discharge seat and the opening and closing of the door panel to the opening of the tape installation area. This significantly reduces the intensity of manual intervention and maintenance costs. The plug-in quick-release structure of the receiving roller and the elastic tension design of the receiving component further simplify the replacement and maintenance process, effectively reducing equipment downtime. In addition, the hydraulic telescopic rod in the feeding mechanism can automatically drive the discharge baffle to open or close, providing operators with convenient space for tape installation and replacement. More importantly, when the discharge seat is removed, the separator plate on it will automatically embed into the limiting groove of the separator frame, forming a linkage to ensure that all separator components move synchronously when switching modes, eliminating errors caused by manual adjustment.

[0036] This embodiment relates to the basic feeding operation of the feeder, which is mainly used to feed the surface-mount components on the tape and reel one by one to the pick-and-place machine. The detailed operation process is as follows: Step 1, Tape and reel installation and initial positioning: The operator removes the coiled tape containing the chip components from the inner cavity and places its core sleeve on the feeding roller 440 of the feeding mechanism 400; Step 2, guiding the tape path and initial tape threading: Pull the front guide of the tape from the feed roller 440 and let it hang down naturally. Guide the tape to wrap around the bottom area of ​​the first receiving roller 332 at a specific wrap angle (this path design uses the curvature of the roller to change the tape direction and provides a tension basis for the subsequent film peeling). At the bottom area of ​​the first receiving roller 332, the operator needs to manually separate the film (protective film) on the upper surface of the front end of the tape from the bottom carrier tape (base tape carrying components) by a small distance (i.e., tear off the film on the upper surface of the front end of the tape). Then, the peeled film end is smoothly wrapped and fixed on the cylinder of the second receiving roller 342. Then, the front end of the carrier tape with the film removed is passed through the material groove 211 on the top surface of the seat box 210, and then wrapped around the bottom of the guide roller 222 of the guide assembly 220. After that, it is wrapped and fixed on the cylinder of the first receiving roller 332.

[0037] Step 3: Start winding and simultaneous stripping: Simultaneously, drive motor 333 (number one) and drive motor 343 (number two) are activated. Both are typically controlled by a control system to maintain synchronized speeds or have tension coordination functions. At this time, take-up roller 342 rotates under the drive of drive motor 343, continuously winding up the film peeled from the tape. Meanwhile, take-up roller 332 rotates under the drive of drive motor 333, pulling the carrier belt forward. As the carrier belt is pulled from the tape roll, the film on it is wound up by take-up roller 342. With the assistance of force and the peeling roller 352, the components are completely peeled off, thus exposing the chip components in the inner cavity of the carrier belt. The carrier belt with the exposed components continues to be conveyed forward and enters the first discharge seat 200A. During continuous operation, the chip components on the carrier belt are conveyed sequentially and continuously to the loading area located outside the material trough 211 on the top surface of the seat box 210. Then, the pick-and-place machine's pick-and-place head (nozzle) is precisely positioned in this loading area and picks up the exposed chip components one by one to complete the subsequent placement operation. Example 2

The drive seat 130 is fixed in the middle part inside the cabinet body 110, and the two sides of the drive seat 130 are respectively connected to a first lifting seat 120A and a second lifting seat 120B. A set of symmetrically arranged bottom rails 114 are fixed on the inner bottom of the cabinet 110. The first lifting seat 120A and the second lifting seat 120B are the same lifting seats. The lifting seat includes a sliding seat plate 121 and a support seat plate 123. Each corner of the sliding seat plate 121 is connected to each corner of the support seat plate 123 through a hydraulic column 122. The sliding seat plates 121 of both lifting seats are slidably connected to a set of bottom rails 114. The drive base 130 includes a fixed base 131, which includes a horizontal top plate and a set of mirror-arranged L-shaped base plates. The two mirror-arranged L-shaped base plates are staggered. A first hydraulic cylinder 132A is fixed on one side of the L-shaped base plate, and a second hydraulic cylinder 132B is fixed on the other side of the L-shaped base plate. The two ends of the top plate of the fixed base 131 are respectively fixed to the two inner side walls of the cabinet 110.

[0039] Specifically, a push plate 1211 is fixed on the top surface of the sliding seat plate 121, the output shaft of the first hydraulic cylinder 132A is connected to the push plate 1211 of the first lifting seat 120A, and the output shaft of the second hydraulic cylinder 132B is connected to the push plate 1211 of the second lifting seat 120B.

[0040] Furthermore, door openings 111 are provided on both sides of the top surface of the cabinet 110, and a sliding groove 112 is provided on the top side of the internal side wall of the cabinet 110, arranged vertically. An electric sliding door assembly is fixed on the top side inside the cabinet 110. The electric sliding door assembly includes a first door panel 141A and a second door panel 141B. The first door panel 141A and the second door panel 141B are door panels of the same size, and the size of the door panels matches the size of the door openings 111. The first door panel 141A is slidably installed on the top. Inside the sliding groove 112, the second door panel 141B is slidably installed in the lower sliding groove 112. A first electric push rod 142A is fixed on one inner wall of the cabinet 110, and a second electric push rod 142B is fixed on the other inner wall of the cabinet 110. The output shaft of the first electric push rod 142A is connected to the first door panel 141A, and the output shaft of the second electric push rod 142B is connected to the second door panel 141B. The extension directions of the first electric push rod 142A and the second electric push rod 142B are opposite.

[0041] This embodiment involves the coordinated operation of the lifting seat and the electric sliding door assembly inside the cabinet 100, enabling flexible removal and storage of the material outlet seat, supporting single-station or dual-station material supply modes. The specific operation process is as follows: A unidirectional feeding method is adopted (for example, using only the No. 1 discharge seat 200A), as detailed below: Step 1: Perform a single door opening operation: The control system issues a command to activate the first electric push rod 142A, causing its output shaft to retract. The retraction action pulls the first door panel 141A, causing it to slide inward (i.e. towards the center of the cabinet 110) within the upper push-pull groove 112, thereby opening the door opening groove 111 on the corresponding side of the top surface of the cabinet 110. At this time, the door opening groove 111 on the other side remains closed, isolating the space on the other side.

[0042] Step 2: Remove the discharge seat from one side: When the drive seat 130 receives the action signal, the first hydraulic cylinder 132A is started, and its output shaft extends outward. The output shaft directly pushes the push plate 1211 of the first lifting seat 120A. Since the sliding seat plate 121 cooperates with the bottom rail 114 through its bottom sliding structure, the entire first lifting seat 120A, together with the first discharge seat 200A fixed on its top surface, slides smoothly along the bottom rail 114 to the outside of the cabinet 110 and reaches the preset working position. Then, the hydraulic columns 122 at the four corners of the first lifting seat 120A are controlled to extend synchronously, driving the upper support seat plate 123 and the first discharge seat 200A on it to rise as a whole until they are completely removed from the cabinet 110. During the removal of the single-sided discharge seat, the No. 1 partition plate 223 will automatically move in tandem, specifically as follows: During the process of the No. 1 discharge seat 200A being moved out of the cabinet 110, its No. 1 partition plate 223 and No. 2 partition plate 230 will move accordingly. During this movement, the bottom of the No. 2 partition plate 230 and the No. 1 partition plate 223 will pass through the U-shaped through groove 314 on the side of the base 310 and finally be embedded in the limiting groove 323 on the side of the partition frame 320 corresponding to the No. 1 discharge seat 200A, forming a plug-in fit. This linkage mechanism ensures that when the position of the partition frame 320 is subsequently adjusted by the screw assembly 313, the No. 1 partition plate 223 and the No. 2 partition plate 230 on the No. 1 discharge seat 200A can move synchronously. If a bidirectional feeding method is adopted (when both feeders 200A and 200B are used simultaneously, in symmetrical double-roll mode, the two rolls of tape flow to opposite feeders, achieving bidirectional independent feeding. This is particularly suitable for production layouts where the same or different components need to be mounted on both sides of the PCB board): Step 1: Perform the double-sided door opening operation: The control system commands electric push rod 142A and electric push rod 142B to start simultaneously, opening door panel 141A and door panel 141B in sync, exposing both upper and lower door opening slots 111. Step 2: Remove the discharge seats from both sides: Hydraulic cylinder 132A and hydraulic cylinder 132B start synchronously, with their respective output shafts extending. Hydraulic cylinder 132A pushes lifting seat 120A to slide outward; hydraulic cylinder 132B pushes lifting seat 120B to slide outward in the opposite direction until it reaches the preset working position. Then, it controls each hydraulic column 122 in lifting seat 120A and lifting seat 120B to extend synchronously, driving the discharge seat 200A and discharge seat 200B to rise as a whole until they are completely removed from cabinet 110. During the removal of the discharge seats on both sides, the No. 1 partition plates 223 on both sides will automatically move in tandem simultaneously, specifically as follows: During the removal process of the two discharge seats, the first partition plate 223 and the second partition plate 230 will be inserted into the limiting grooves 323 on both sides of the partition frame 320 respectively, forming a plug-in fit. This linkage mechanism ensures that when the position of the partition frame 320 is adjusted by the screw assembly 313, the first partition plate 223 and the second partition plate 230 on the first discharge seat 200A and the second discharge seat 200B can move synchronously.

A lead screw assembly 313 is fixed on the bottom side of the middle position of the base 310, and the lead screw assembly 313 is connected to the partition frame 320. The lead screw assembly 313 drives the partition frame 320. The first discharge baffle 430A and the second discharge baffle 430B are the same discharge baffle. The horizontal support base 410 includes a U-shaped support base 411, a connecting bent rod 412 and a hydraulic telescopic rod 413. The hydraulic telescopic rod 413 is fixed in the inner groove on both sides of the U-shaped support base 411.

[0044] Specifically, the first insertion hole 441 and the second insertion hole 442 are insertion holes with the same diameter. The circular partition plate 420 and the feeding roller 440 are limited by the pin 422 and the corresponding insertion hole. The through grooves on both sides of the circular partition plate 420 are slidably installed on the U-shaped support base 411 of the horizontal support base 410 on both sides.

[0045] Furthermore, the top of the middle position of the partition frame 320 is connected to the circular partition plate 420, and the tops of the two sides of the partition frame 320 are respectively fixed with screws to the first Y-shaped partition plate 3201, the second Y-shaped partition plate 3202 and the third partition plate 3203. The first Y-shaped divider 3201 is used to divide the first storage roller 332. The first Y-shaped divider 3201 has a U-shaped opening at the top. The first storage roller 332 is placed in the U-shaped opening of the first Y-shaped divider 3201. The first Y-shaped divider 3201 is fixed to the corresponding U-shaped groove 322 at the top of the divider frame 320 by bolts. The second Y-shaped divider 3202 is used to separate the second receiving roller 342. The second Y-shaped divider 3202 has a U-shaped opening at the top. The second receiving roller 342 is placed in the U-shaped opening of the second Y-shaped divider 3202. The second Y-shaped divider 3202 is fixed to the corresponding U-shaped groove 322 at the top of the divider frame 320 by bolts. The third partition plate 3203 is used to separate the peeling roller 352. The third partition plate 3203 is slidably connected to the peeling roller 352. The ring end of the third partition plate 3203 is sleeved on the peeling roller 352. The bottom connecting end of the third partition plate 3203 is fixed in the corresponding U-shaped groove 322 at the top of the partition frame 320 by bolts. A U-shaped base plate 423 is fixed to the bottom of the circular partition plate 420. The bottom connecting end of the U-shaped base plate 423 is fixed to the corresponding U-shaped groove 322 at the top of the partition frame 320 by bolts.

[0046] In this embodiment, the movable separator 320 switches between single-feed channel and dual-feed channel feeding. The specific operation process is as follows: When using a unidirectional feeding method, a single feeding channel can be used (a single feeding channel is suitable for both small and large-size tapes), or a dual feeding channel can be used (a dual feeding channel is suitable for small-size tapes), as detailed below: When using a single feeding channel, first start the drive motor of the lead screw assembly 313 to drive the separator 320 to move, causing the first Y-shaped separator 3201, the second Y-shaped separator 3202, the third separator 3203, the second separator 230, the first separator 223, and the circular separator 420 on one side to move inward (towards the side of the base 310) to the preset innermost side (i.e., the initial position), forming an independent feeding channel. Then, insert the pin 422. The second insertion hole 442, this independent feeding channel, when installing the tape, drives the first feeding baffle 430A to move outward by activating the hydraulic telescopic rod 413 on one side, automatically opening the tape installation area (i.e., the area between the first feeding baffle 430A and the outer end of the feeding roller 440). Then, the operator can directly install the tape from one end of the feeding roller 440 onto the feeding roller 440. This independent feeding channel can be configured with both large and small tapes. The pick and place machine picks up the material from the feeding area of ​​this feeding channel. When using a dual-feed channel, first start the drive motor of the lead screw assembly 313 to drive the separator frame 320 to move, which in turn moves the first Y-shaped separator 3201, the second Y-shaped separator 3202, the third separator 3203, the second separator 230, the first separator 223, and the circular separator 420 simultaneously. This separates the first receiving roller 332, the second receiving roller 342, the stripping roller 352, and the feeding roller 440, forming two completely independent feeding channels. Then, insert the pin 422 into the first insertion hole 441, so that the feeding roller 440 is located in the center of the circular separator 420. When installing the tape, the two feeding channels are connected. By activating the hydraulic telescopic rods 413 on both sides, the No. 1 feeding baffle 430A and the No. 2 feeding baffle 430B are driven to move outward, automatically opening the tape mounting areas on both sides (i.e., the area between the No. 1 feeding baffle 430A and the outer end of the feeding roller 440 and the area between the No. 2 feeding baffle 430B and the inner end of the feeding roller 440). Then, the operator can directly install the two tapes from both ends of the feeding roller 440 onto the feeding roller 440. The two feeding channels can be configured with two tapes of the same size or two tapes of different sizes (such as simultaneously mounting two different components) and feed materials to the same side at the same time. The pick-and-place machine can simultaneously pick up materials from the loading areas of the two feeding channels. When using a bidirectional feeding method, a dual feeding channel is used, as detailed below: The drive motor of the lead screw assembly 313 is started, which drives the separator frame 320 to move. This causes the first Y-shaped separator 3201, the second Y-shaped separator 3202, the third separator 3203, the second separator 230, the first separator 223, and the circular separator 420 to move synchronously. This simultaneously separates the first receiving roller 332, the second receiving roller 342, the stripping roller 352, and the feeding roller 440, forming two completely independent feeding channels. Then, the pin 422 is inserted into the first insertion hole 441, so that the feeding roller 440 is located in the center of the circular separator 420. The two feeding channels can be configured with two tapes of the same size or two tapes of different sizes (such as simultaneously mounting two different components), feeding materials to both sides respectively. The pick-and-place machine can simultaneously or alternately pick up materials from the feeding areas on both sides. Before moving the discharge seat back to the cabinet 110, the partition frame 320 needs to be moved first, which will cause the corresponding second partition plate 230 and the first partition plate 223 to move inward and return to the preset initial position (i.e., the position close to the side plate of the base 310).
