[0002] A pick-and-place machine, also known as a surface mount system, is a device that is placed on PCB pads by moving a placement head after a dispensing machine or screen printer in a production line.

[0003] Pick-and-place machines require a large amount of material during operation, and this is achieved by placing the material to be used in several feed slots for the machine to retrieve. In existing technology, movable nozzles or robotic arms are often used to place the material onto different feed slots. The position of the nozzle or arm is adjusted to place the material onto different discharge slots. However, this method requires high positioning accuracy from the robotic arm or nozzle, results in high equipment costs, and is not effective in improving feeding efficiency, thus hindering production efficiency.

[0031] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0032] The technical solutions of this application and their effects are described below through several exemplary embodiments. It should be noted that the following embodiments can be referenced, borrowed from, or combined with each other. Identical terms, similar features, and similar implementation steps in different embodiments will not be repeated.

[0033] The feeding assembly and bulk material feeder for the chip mounter provided in this application are intended to solve at least one technical problem existing in the prior art.

[0034] Optionally, such as Figures 1-4 As shown, the feeding assembly of this application includes a first drive module 71, a feeding plate 72, and a blowing plate 73. The top of the blowing plate 73 is provided with a first region and a second region. The first region is located at the bottom of the feeding plate 72, and the second region is opposite to the feeding end of the feeding plate 72. The side of the feeding plate 72 away from the first region is provided with a plurality of feeding grooves 86. The second region is provided with a plurality of discharge grooves 74 corresponding to the feeding grooves 86. The discharge grooves 74 are used to place materials. The first drive module 71 is connected to the bottom of the blowing plate 73 and is used to drive the blowing plate 73 to move in a direction perpendicular to the feeding grooves 86 so that the discharge grooves 74 containing materials are connected to the feeding grooves 86 to be fed. The groove wall of the discharge groove 74 opposite to the feeding plate 72 is provided with a first air hole 76 so as to blow materials into the feeding grooves 86 by the airflow blown out from the first air hole.

[0035] Alternatively, the material can be LED chips, IC chips, and other materials required for the operation of the pick-and-place machine.

[0036] Optionally, the first drive module 71 can be a linear module equipped with a motor, which drives the linear movement of the blowing plate 73. The motor can be a lead screw motor or other servo motors that can be precisely controlled. Through precise control of the motor, each movement of the blowing plate 73 ensures that a discharge trough 74 is located at the material placement area, thereby placing the material into the discharge trough 74.

[0037] Optionally, the first drive module 71 drives the blowing plate 73 to reciprocate. The discharge trough 74 and the feed trough 86 are equally spaced, and the distance between the discharge troughs 74 can be half the distance between the feed troughs 86.

[0038] Optionally, the number of feed troughs 86 and discharge troughs 74 can be the same, and their specific numbers can be determined according to production needs.

[0039] In one embodiment, the number of discharge troughs 74 and feed troughs 86 is 10 each. The discharge troughs 74 on the blowing plate 73 are numbered starting from 1. When the blowing plate 73 moves towards the feed plate 72, material is placed into the discharge trough 74 with an odd number, meaning there is a gap of one discharge trough 74 between adjacent materials. Conversely, when the blowing plate 73 moves towards the other side of the feed plate 72, material is placed into the discharge trough 74 with an even number. This method allows for continuous material discharge without needing to move the blowing plate 73 back to its original position, effectively improving discharge efficiency. Specifically, the feed troughs 86 can be divided into two groups. When the blowing plate 73 moves in one direction, material is discharged from the discharge trough 74 corresponding to one group of feed troughs 86 and blown into that group of feed troughs 86. When the blowing plate 73 moves in the other direction, material is discharged from the discharge trough 74 corresponding to the other group of feed troughs 86 and blown into that group of feed troughs 86.

[0040] Optionally, the feeding assembly further includes a second drive module 84. The feeding plate 72 includes a first material plate 81 and a second material plate 85. The first material plate 81 is located above the first area, and the second material plate 85 is located on the side of the first material plate 81 away from the discharge trough 74. The feeding trough 86 is arranged on the same side of the first material plate 81 and the second material plate 85, and the feeding troughs 86 on the first material plate 81 and the second material plate 85 are connected one to one. The drive end of the second drive module 84 is connected to the bottom of the second material plate 85 and is used to drive the second material plate 85 to vibrate. By dividing the feeding plate 72 into two parts, the vibration of the feeding trough 86 is avoided when the material moves from the discharge trough 74 to the feeding trough 86.

[0041] Optionally, the second drive module 84 can be a linear vibration motor, which drives the second material plate 85 to vibrate linearly, thereby causing the material on the second material plate 85 to move within the feed trough 86.

[0042] Optionally, the first air hole 76 penetrates the blowing plate 73, and the blowing plate 73 is provided with an air nozzle that communicates with the first air hole 76. The air pump inputs compressed air into the first air hole 76 through the air nozzle, and uses the compressed air to blow the material in the discharge trough 74 into the feed trough 86 on the first material plate 81. Furthermore, by controlling the amount of compressed air, the material can be moved from the first material plate 81 to the second material plate 85.

[0043] Optionally, the feeding assembly further includes a cover plate 82, which is fixed to the first material plate 81 and covers the feeding slots 86 on the first material plate 81. The cover plate 82 can cover all the feeding slots 86 on the first material plate 81. The cover plate 82 may have through holes for fixing the cover plate 82, through which screws or other components for fixing the cover plate 82 are inserted into the first material plate 81, thereby preventing material from falling out of the feeding slots 86.

[0044] Optionally, to prevent material from detaching from the discharge trough 74, the cover plate 82 has a blocking part and a discharge port 83 on the side away from the second material plate 85. The blocking part covers the discharge trough 74, and the discharge port 83 is located on the blocking part. The position of the discharge port 83 corresponds to the position of the discharge trough 74, and the material is placed into the discharge trough 74 through the discharge port 83. The size of the discharge port 83 corresponds to the size of the discharge trough 74. Each time material is discharged, the first drive module 71 moves one of the discharge troughs 74 on the blowing plate 73 to below the discharge port 83, thereby placing the material into the discharge trough 74.

[0045] Optionally, the bottom of the discharge trough 74 is also provided with a second air hole 75, which is used to adsorb the material in the discharge trough 74. The second air hole 75 penetrates the blowing plate 73, and the blowing plate 73 is provided with an air nozzle corresponding to the second air hole 75. The air pump draws air through the air nozzle and the second air hole 75, thereby achieving the purpose of adsorbing material through the second air hole 75.

[0046] The feeding assembly provided in this application includes a first drive module 71, a blowing plate 73, and a feeding plate 72. The top of the blowing plate 73 has a first region and a second region. The first region is located at the bottom of the feeding plate 72, and the second region is opposite to the feeding end of the feeding plate 72. A plurality of feeding grooves 86 are provided on the side of the feeding plate 72 away from the first region, and a plurality of discharge grooves 74 corresponding to the feeding grooves 86 are provided in the second region. The discharge grooves 74 are used to place materials. The first drive module 71 is connected to the bottom of the blowing plate 73 and is used for… The blowing plate 73 is driven to move in a direction perpendicular to the feeding trough 86 so that the feeding trough 74 containing the material is connected to the feeding trough 86 to be fed; the wall of the feeding trough 74 opposite to the blowing plate 73 is provided with a first air hole 76 so that the material is blown into the feeding trough 86 by the airflow blown out from the first air hole 76. In this embodiment, the material can be transported to different feeding troughs 86 by moving the feeding trough 74, thereby effectively avoiding the movement of the feeding device, reducing the position accuracy requirements and equipment costs, and improving feeding efficiency and production efficiency.

[0047] Based on the same inventive concept, embodiments of this application also provide a bulk material feeder for a chip mounter, such as... Figures 1-6 As shown, the bulk material feeder of this application includes a feeding assembly as described in the above embodiments, which is used to supply materials to the chip mounter.

[0048] Optionally, the bulk material feeder includes a body 1 and a control unit. The control unit is installed on the body 1, and the feeder also includes a feeding assembly 6 installed on the body 1 and electrically connected to the control unit. The body 1 serves as a mounting carrier for mounting the other components, and the control unit is used to control the operation of the other modules.

[0049] The feeding assembly 6 includes a material conveying module, a first straightening module, a detector 66, a waste pipe 67, a steering module, and a second straightening module. The material conveying module is used to transport materials, which can be loose LED beads. The following description uses loose LED beads as the material.

[0050] The feeding assembly 6 sequentially transports loose LED beads to the first straightening module, detector 66, waste pipe 67 or the steering module and the second straightening module. The feeding assembly 6 includes a cam divider 61, a turntable 62 and several suction nozzles 63. The cam divider 61 is fixedly installed on the machine body 1. The turntable 62 is mounted on the cam divider 61. The cam divider 61 can push the turntable 62 up and down while rotating the turntable 62 quantitatively. Several suction nozzles 63 are evenly installed on the turntable 62. The suction nozzles 63 are connected to corresponding vacuum equipment, so that negative pressure is generated at the suction nozzles 63, thereby sucking up the LED beads. The first straightening module, detector 66, waste pipe 67, steering module and the second straightening module are arranged in a circle and sequentially installed below the turntable 62, so that the suction nozzles 63 at the turntable 62 can sequentially transport the LED beads to the above modules.

[0051] The detector 66 is used to detect the performance of the corresponding LED beads to prevent faulty LED beads from entering the pick-and-place machine. The LED bead detector 66 is equipped with corresponding test electrodes. Several test electrodes are installed on the mounting base, and the position of the test electrodes is adapted to the LED beads. The nozzle 63 picks up the LED bead and places it at the detector 66, so that the test electrodes make contact with the contacts of the LED bead one by one, and then tests the LED bead. If the electrical signal detected after the test electrode contacts the pin of the LED bead is the preset electrical signal, it means that the LED bead is powered on and tested normally. At the same time, the pin direction of the LED bead is detected according to the detected electrical signal to verify whether the LED's posture is the preset posture (such as the pins of the LED bead facing the preset direction). If the LED bead is in the reverse state, or the LED bead is defective and does not emit light, the detected electrical signal is not the preset electrical signal. The LED bead is identified as unqualified material. When the unqualified material is moved by the corresponding nozzle 63 to the top of the waste tube 67, the corresponding nozzle 63 releases the LED bead into the waste tube 67.

[0052] Optionally, the control unit includes a controller and a control panel 2. The controller is installed inside the machine body 1. The controller can be a control host, a PLC programmable controller, or other control devices, which are existing mature products and will not be described in detail here. The control panel 2 is installed on the machine body 1 and is used to operate the device. The controller is electrically connected to the control panel 2, the feeding assembly 6, and other components on the bulk material feeder. The controller controls the operation of various electrical components of the device.

[0053] Optionally, the bulk material feeder also includes a hopper 3, a vibrating plate 4, and a feeding track 5. The hopper 3 is fixedly installed on the machine body 1, and the material output end at the bottom of the hopper 3 is connected to the vibrating plate 4, allowing the hopper 3 to convey bulk materials onto the vibrating plate 4. The material output end of the hopper 3 can also be equipped with a corresponding vibration device and a material transmission track 31. One end of the material transmission track 31 is opposite to the discharge port at the bottom of the hopper 3, and the other end extends above the vibrating plate 4. The vibration device is equipped with an electromagnet, which is connected to the material transmission track 31. When the controller detects that there is a lack of material on the vibrating plate 4, it controls the electromagnet to open and close rapidly, thereby driving the material transmission track 31 to vibrate, causing the material on the material transmission track 31 to fall into the vibrating plate 4. The vibrating plate 4 is connected to one end of the feeding track 5, and the other end of the feeding track 5 extends into the material picking range of the suction nozzle 63. The vibratory feeder 4 transports the LED beads to the feeding track 5. The LED beads are arranged in rows in the feeding track 5 and move towards the picking range, so that the suction nozzle 63 of the feeding component 6 can pick up the LED beads.

[0054] Optionally, the first straightening module and the second straightening module have the same structure. The first straightening module includes a bracket, a first straightening chuck 64, and a first straightening motor 65. The first straightening chuck 64 is fixedly mounted on the machine body 1 by the bracket. The first straightening motor 65 is mounted on the machine body 1, and the output shaft of the first straightening motor 65 is connected to the first straightening chuck 64. The top of the first straightening chuck 64 is provided with multiple claws, which are used to correct the posture of the material adsorbed by the suction nozzle 63. When the suction nozzle 63 moves above the first straightening chuck 64, the turntable 62 descends, causing the LED beads adsorbed by the suction nozzle 63 to descend into the posture correction area in the claws. The first straightening motor 65 starts, causing the claws of the first straightening chuck 64 to tighten, thereby gripping the LED beads and correcting their posture to achieve positioning. After positioning, the first straightening motor 65 actuates again, causing the claws of the first straightening chuck 64 to loosen, thereby releasing the LED beads. Similarly, the second straightening module includes a bracket, a second straightening chuck 612, and a second straightening motor 613. The second straightening chuck 612 is fixedly mounted on the machine body 1 by the bracket. The second straightening motor 613 is mounted on the machine body 1 and its output shaft is connected to the second straightening chuck 612. When the second straightening motor 613 is started, it can drive the jaws of the second straightening chuck 612 to tighten or loosen, thereby causing the second straightening chuck to grip or loosen the LED beads and position them.

[0055] In one embodiment, both the first straightening chuck 64 and the second straightening chuck 612 are four-jaw chucks to accommodate materials of a specific shape (such as rectangular LED beads).

[0056] Optionally, the steering module includes a steering wheel 68, a steering motor 69, a mounting bracket 610, and a transmission mechanism 611. The steering wheel 68 is rotatably mounted on the mounting bracket 610 for steering the LED beads. The mounting bracket 610 is fixedly mounted on the body 1. The steering motor 69 is mounted on the body 1 and connected to the steering wheel 68 via the transmission mechanism 611, allowing the drive motor to rotate the steering wheel 68 through the transmission mechanism 611. The transmission mechanism 611 can be a belt drive mechanism, a sprocket and chain drive mechanism, or a gear drive mechanism, or other transmission-capable device. The steering wheel 68 has a placement slot for placing qualified LED beads. After the LED beads are tested using the detector 66, the suction nozzle 63 places the LED beads into the placement slot, and the transmission mechanism 611 rotates the steering wheel 68, thereby adjusting the LED beads to a preset posture.

[0057] Optionally, a plasma fan 9 is installed on the body 1. The plasma fan 9 is located above the vibratory plate 4. The plasma fan 9 blows air onto the vibratory plate 4 to prevent excessive static electricity in the LED beads in the vibratory plate 4 from affecting subsequent processing.

[0058] The following section will further explain the bulk material feeder through its specific working process.

[0059] In one embodiment, when using the bulk material feeder of this application to feed materials to a chip mounter, bulk LED beads are first placed in the hopper 3. The hopper 3 then conveys the LED beads to the vibratory feeder 4 via the material transfer track 31. The vibratory feeder 4 then vibrates to convey the LED beads to the feeding track 5. The vibration of the vibratory feeder 4 causes the LED beads to be vibrated so that their leads are facing down. Furthermore, when the vibratory feeder 4 conveys the LED beads to the feeding track 5 in a queue, it can also detect whether the LED beads are in a lead-down state. If not, the LED bead is removed from the queue to avoid affecting the subsequent processing of other LED beads.

[0060] The feeding track 5 can arrange the LED beads in rows. Then the feeding assembly 6 is started. The cam divider 61 drives the turntable 62 to move up and down while rotating quantitatively. When the turntable 62 descends, the corresponding suction nozzle 63 moves to the suction position of the feeding track 5. The suction nozzle 63 can pick up the LED beads. The cam divider 61 continues to work, so that while the turntable 62 moves up and down in a cycle, each suction nozzle 63 picks up the LED beads in sequence and places them at the first straightening chuck 64, the detector 66, the steering wheel 68, the second straightening chuck 612 and the blowing plate 73.

[0061] When the suction nozzle 63 places the LED bead on the first straightening chuck 64, the suction nozzle 63 can maintain the state of adsorbing the LED bead. The first straightening motor 65 starts and drives the chuck on the first straightening chuck 64 to work, clamping the LED bead into the correct position and completing the positioning of the LED bead. When the suction nozzle 63 moves the LED bead, the first straightening chuck 64 resets and releases the LED bead, so that the suction nozzle 63 can move the LED bead smoothly.

[0062] Subsequently, the suction nozzle 63 places the LED bead on top of the detector 66. The detector 66 detects the performance of the LED bead through electrodes connected to the pins of the LED bead at its top. If the LED bead is defective or undetectable, it is released into the waste tube 67 by the suction nozzle 63 as it passes over the waste tube 67. If the LED bead is detected as qualified and its posture is a preset posture, it is released into the second straightening chuck 612 by the suction nozzle 63. If the detector 66 detects that the LED bead is a qualified product, but the LED bead's posture is not the preset posture (e.g., the orientation of each pin is not the preset orientation), then the suction nozzle 63 moves the LED bead to the steering wheel 68. The steering wheel 68 turns the LED bead according to the detection result of the detector 66, so that the LED bead's posture is the preset posture. The steering wheel 68 then rotates under the action of the steering motor 69 and the transmission mechanism 611, thereby causing the LED bead placed in the slot in the middle of the steering wheel 68 to rotate to the predetermined direction. The suction nozzle 63 moves the LED bead after the rotation is completed to the second straightening chuck 612. At this time, the suction nozzle 63 still adsorbs the LED bead. The working principle of the second straightening chuck 612 is the same as that of the first straightening chuck 64. After the second straightening chuck 612 repositions the LED beads, the suction nozzle 63 moves the LED beads to the top of the discharge port 83 of the cover plate 82. The suction nozzle 63 descends and places the LED beads into the discharge slots 74 of the blowing plate 73. Under the action of the first drive module 71, the blowing plate 73 moves gradually, so that the LED beads are placed in each discharge slot 74 of the blowing plate 73 in sequence. Under the action of the air pump, the second air hole 75 at the discharge slot 74 causes the LED beads to be adsorbed in the discharge slot 74. After the LED beads are placed (such as after a set of LED beads are placed), the second air hole 75 stops adsorbing the LED beads. Under the action of the air pump, the first air hole 76 at the blowing plate 73 generates a blowing airflow, which can blow the LED beads in the discharge slots 74 into the feed slot 86.

[0063] Subsequently, the LED beads are moved towards the second material plate 85 by the blowing airflow in the relatively closed channel formed by the feed groove 86 on the cover plate 82 and the first material plate 81, until the LED beads enter the feed groove 86 on the second material plate 85. Under the direct vibration of the second drive module 84, each LED bead is arranged in a row at the feed groove 86 on the second material plate 85, which makes it easier for the pick-and-place machine to pick up the loose LED beads.

[0064] This bulk material feeder can quickly arrange bulk materials into rows using a hopper 3, a vibrating plate 4, and a feeding track 5. Then, the feeding assembly 6 positions, tests, and transports the bulk materials, adjusting them to a predetermined orientation. The feeding assembly 6 then transports the oriented bulk materials to the feeding assembly, where the pick-and-place machine can quickly grab the bulk materials from the feeding trough 86. This device can efficiently and quickly discharge bulk materials, effectively improving the feeding efficiency of the pick-and-place machine and thus increasing its production efficiency.
