Description

Technical Field

[0001] This utility model relates to the field of feeding equipment, and in particular to a tray conveying device for a disc feeder. Background Technology

[0002] The disc feeder is a device used in pick-and-place machines for the precise feeding of chip components. It features a compact structure and high efficiency and stability, and is mainly used in electronic manufacturing and process testing in research institutions. The tray conveyor is one of the important components of the disc feeder. A reliable and effective tray conveyor is a necessary component for the efficient operation of the disc feeder. In SMT production lines, pick-and-place machines typically employ a multi-layer structure design. The feeder needs to horizontally transport the trays carrying components a certain distance before lifting them upwards to a height accessible to the placement head. Existing devices only have unidirectional horizontal transport capabilities and lack convenient and reliable transfer structures, making it impossible to automate the entire process of transport and transfer. Furthermore, the clamping structure at the tray is not automatic or convenient enough, exhibiting a low degree of automation and failing to meet the requirements of high-speed pick-and-place machines. Therefore, we propose a tray transport device for a tray feeder. Utility Model Content

[0003] The technical problem this invention aims to solve is to overcome existing defects and provide a tray conveying device for a disc feeder. This device is equipped with horizontal and vertical moving modules, enabling efficient tray conveying. It also features a gripper mechanism for automatic tray loading, unloading, and return, effectively improving the automation level of the feeding process and meeting the needs of high-speed placement machines. Furthermore, this device has a detachable support plate and an automatic clamping mechanism, allowing the support plate with the tray to be easily connected to the conveying components, effectively solving the problems in the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a pallet conveying device for a disc feeder, comprising a conveying channel, a pallet conveying unit, and a gripper picking and placing unit; Conveying channel: It is set longitudinally and its vertical section is a U-shaped structure. The rear end of the conveying channel is a single plate and an inverted F-shaped mounting bracket is placed in the middle. The mounting bracket is fixed to the rear end of the conveying channel by bolts on the lower side. Pallet conveying unit: installed on the inner corner side of the conveying channel; The gripper unit includes a second ball screw, a motor bracket, a lifting plate, a hydraulic cylinder, grippers, pads, a pressure sensor, and an encoder. The vertical section of the mounting frame is hollow, and a second ball screw is installed vertically in the middle of the inner side. The drive motor of the second ball screw is located at the corresponding vertical position on the lower side of the mounting frame, and a motor bracket is fixedly mounted on the outer side. The motor bracket is fixedly connected to the lower end of the mounting frame. The lifting plate is embedded in the upper platform of the inverted F-shaped mounting frame. The nut component of the second ball screw is fixedly connected to the rear end of the lifting plate. Four mounting slots are opened on the front side of the lifting plate. A hydraulic cylinder is embedded in each slot. An encoder (410) is installed at each hydraulic cylinder. The telescopic ends of two corresponding hydraulic cylinders face away from each other. The telescopic ends of the hydraulic cylinders are fixedly connected to grippers, which extend upwards. Two strip-shaped pads are fixedly connected to the upper end of the lifting plate, and a pressure sensor is installed between the two pads. The pressure sensor includes upper and lower detection ends.

[0005] The conveyor channel is used for the installation of various components of the pallet conveying unit, thereby conveying the pallets. The mounting bracket is used for the installation of the second ball screw and the lifting pallet. The second ball screw drives the lifting pallet to move up and down. When the pallet moves to the end of the conveyor channel, the lifting pallet rises to lift the pallet upwards. When the pressure sensor located on the upper side detects contact with the bottom of the pallet assembly, the hydraulic cylinders are activated, causing the grippers to clamp onto the outer edge of the pallet assembly, thereby gripping the pallet assembly and achieving a locking effect to ensure stability during the lifting process. The encoder is used for real-time monitoring. The pressure value inside each hydraulic cylinder ensures that the extension and retraction length of each hydraulic cylinder rod is consistent, ensuring a stable clamping effect of the grippers. When the lifting pallet drives the push plate to descend, the insert rod installed at the lower end of the lifting pallet can be reset and inserted into the mounting socket of the pallet conveying unit. The pressure sensor located on the lower side contacts the bottom of the mounting frame, and the four grippers are released, allowing the pallet conveying unit to send the empty pallet back outward. The pad block can play a buffering and protective role when the lifting pallet initially contacts the pallet assembly. The motor bracket is used to fix the drive motor of the ball screw.

[0006] Furthermore, the gripper placement unit also includes guide rods and guide sleeves. Two vertical guide rods are fixedly connected to the inner side of the vertical section of the mounting frame, and two guide sleeves are fixedly connected to the tail of the lifting pallet. The two guide rods pass through the inside of one guide sleeve and maintain a slidable connection with it. The guide rods and guide sleeves cooperate to guide the lifting of the lifting pallet, and the auxiliary limiting effect of the two guide rods prevents the nut component and the lifting pallet from rotating horizontally during the operation of the ball screw, ensuring stable lifting of the lifting pallet.

[0007] Furthermore, the pallet conveying unit includes mounting rails, a ball screw, fixed feet, mounting sockets, elastic blocks, a bearing plate seat, and insert rods. A longitudinal mounting rail is fixedly connected to each of the two inner corners of the conveying channel. A ball screw is installed inside the mounting rail. The drive motor of the ball screw is located at the front of the mounting rail and is equipped with an encoder assembly. A fixed foot is fixedly connected to the side of the drive motor closest to the conveying channel, and the fixed foot is fixedly connected to the conveying channel by bolts. A rectangular mounting socket is fixedly connected to the upper side of the nut component of the ball screw. The upper end of the mounting socket has two mounting slots, one at the front and one at the back. The bearing plate seat is horizontally positioned, and a vertical insert rod is fixedly connected to each of the four corners at the lower end. The insert rods are respectively inserted into the interior of a mounting slot. A rectangular groove is formed at the upper end of the bearing plate seat, and folded elastic blocks are fixedly connected at equal intervals on the inner wall of the groove. The mounting rail is used for the installation of ball screw one, which drives the mounting socket to move. The groove at the upper end of the support plate is used for placing the tray. When the operator performs a single feeding operation, the tray filled with electronic components is first clamped to the detachable support plate. After the tray is placed, the elastic block on the inner wall of the groove can lock and fix the tray through the elastic force. Then, the support plate is connected to the conveying component. The support plate is inserted into the slot inside the mounting socket through the bottom plug rod. After the tray is installed, ball screw one starts and drives the tray to convey backward. The encoder assembly equipped with ball screw one can monitor the speed of the two drive motors in real time and make real-time feedback adjustments to achieve speed synchronization, thereby realizing the synchronous movement of the mounting sockets on the left and right sides.

[0008] Furthermore, the pallet conveying unit also includes a telescopic short shaft, clamping blocks, and springs. Each mounting slot at the upper end of the mounting socket has a set of clamping blocks installed inside. The two sets of clamping blocks on the rear side are arranged horizontally, and the two sets on the front side are arranged vertically. The upper ends of opposite sides of each set of clamping blocks have a chamfered structure. A telescopic short shaft is fixedly connected to the back of each set of clamping blocks, and the other end of the telescopic short shaft is fixedly connected to the inner wall of the mounting slot. A spring is fitted on the outer side of each telescopic short shaft. The telescopic short shaft is used for installing the clamping blocks and springs. The chamfered structure at the upper end of the clamping blocks facilitates the insertion of the insertion rod. Under the action of the springs, each set of clamping blocks clamps and fixes the insertion rod at the lower end of the support plate seat. The front and rear sets of clamping blocks are perpendicular to each other, providing clamping action in two directions for the insertion rod, thereby preventing horizontal displacement of the support plate seat and ensuring its installation stability.

[0009] Furthermore, it also includes right-angle brackets, mounting holes, and diagonal supports. Two right-angle brackets are fixedly connected to the lower end and rearward side of the conveying channel. The horizontal ends of the right-angle brackets are fixedly connected to the bottom of the conveying channel by bolts. Mounting holes are provided in the vertical sections of the right-angle brackets. The two ends of the diagonal supports are fixedly connected to the two ends of the right-angle brackets, respectively. The horizontal ends of the right-angle brackets support the conveying channel, the mounting holes in the vertical sections of the right-angle brackets are used for bolt installation, thereby fixing the right-angle brackets to external equipment. The diagonal supports improve the structural stability of the right-angle brackets.

[0010] Furthermore, it also includes ribs, which are also right-angled triangular structures and are snapped onto the inside of the right-angle end of the right-angle bracket. The two ends of the ribs are fixedly connected to the right-angle bracket by hexagonal bolts. By snapping the ribs onto the inside of the right-angle end of the right-angle bracket, the load-bearing capacity of the right-angle bracket can be improved.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: The tray conveying device of this disc feeder has the following advantages: 1. This device is equipped with horizontal and vertical moving modules, which can effectively complete the transport of pallets. It is also equipped with a gripper mechanism, which can realize the automatic picking, placing and returning of pallets: During feeding, the pallet conveying unit transports the pallet assembly from front to back. When the pallet moves to the end of the conveying channel, the lifting pallet rises and lifts the pallet upward. When the pressure sensor detects contact with the bottom of the pallet assembly, each hydraulic cylinder is activated, which drives the gripper to clamp on the outside of the pallet assembly frame, realizing the gripping and locking of the pallet assembly. 2. It can effectively improve the automation level of the feeding process and adapt to the needs of high-speed chip mounters: After the feeding is completed, the lifting pallet drives the push plate to descend. The plug installed at the lower end of the lifting pallet can be reset and inserted into the mounting socket of the pallet conveying unit. When the pressure sensor located on the lower side contacts the bottom of the mounting frame, the four grippers are released, which allows the pallet conveying unit to send the empty pallet back outward. 3. It features a detachable support plate base and an automatic clamping mechanism, enabling easy connection between the support plate base containing the pallet and the conveying components: The groove at the top of the support plate base is for placing the pallet. During a single feeding operation, the operator first clamps the pallet filled with electronic components to the detachable support plate base. After the pallet is placed, the elastic block on the inner wall of the groove can clamp and fix the pallet through elastic force. Then, the support plate base is connected to the conveying components. The support plate base is inserted into the slot inside the mounting socket through the bottom insert rod. After the pallet is installed, the ball screw starts, driving the pallet to be conveyed backward. Attached Figure Description

The pressure sensor 47 includes upper and lower detection ends.

[0021] Conveying channel 1 is used for the installation of various components of pallet conveying unit 3, thereby conveying the pallet. Mounting bracket 2 is used for the installation of ball screw 41 and lifting pallet 43. Ball screw 41 drives lifting pallet 43 to move up and down. When the pallet moves to the end of conveying channel 1, lifting pallet 43 rises to lift the pallet. When the pressure sensor 47 on the upper side detects contact with the bottom of the pallet assembly, each hydraulic cylinder 44 is activated, driving the gripper 45 to clamp onto the outer edge of the pallet assembly, thereby gripping the pallet assembly and achieving a locking effect to ensure stability during the lifting process. Encoder 410 is used to monitor each hydraulic cylinder in real time. The pressure value inside cylinder 44 ensures that the extension and retraction lengths of the rods of each hydraulic cylinder 44 are consistent, ensuring a stable clamping effect of the grippers 45. When the lifting pallet 43 drives the push plate to descend, the insert rod 310 installed at the lower end of the lifting pallet 43 can be reset and inserted into the mounting socket 34 of the pallet conveying unit 3. The pressure sensor 47 located on the lower side contacts the bottom of the mounting bracket 2, and the four grippers 45 are released, thus allowing the pallet conveying unit 3 to send the empty pallet back outward. The pad block 46 can play a buffering and protective role when the lifting pallet 43 initially contacts the pallet assembly. The motor bracket 42 is used to fix the drive motor of the ball screw 41.

[0022] The gripper placement unit 4 also includes guide rods 48 and guide sleeves 49. Two vertical guide rods 48 are fixedly connected to the inner side of the vertical section of the mounting frame 2, and two guide sleeves 49 are fixedly connected to the tail of the lifting pallet 43. The two guide rods 48 pass through the interior of one guide sleeve 49 and maintain a sliding connection with it. The guide rods 48 and guide sleeves 49 cooperate to guide the lifting of the lifting pallet 43. Furthermore, the auxiliary limiting effect of the two guide rods 48 prevents the nut component of the ball screw 41 from rotating horizontally during operation, ensuring stable lifting of the lifting pallet 43.

[0023] The pallet conveying unit 3 includes a mounting rail 31, a ball screw 32, a fixing foot 33, a mounting socket 34, an elastic block 36, a bearing plate seat 35, and a plug rod 310. A longitudinal mounting rail 31 is fixedly connected to each of the two inner corners of the conveying channel 1. A ball screw 32 is installed inside the mounting rail 31. The drive motor of the ball screw 32 is located at the front of the mounting rail 31 and is equipped with an encoder assembly.

A rectangular mounting socket 34 is fixedly connected to the upper side of the nut component of the ball screw 32. The upper end of the mounting socket 34 has two mounting slots, one in the front and one in the back. The bearing plate base 35 is arranged horizontally, and a vertical insertion rod 310 is fixedly connected to each of the four corners at the lower end. The insertion rod 310 is inserted into the interior of a mounting slot respectively. A rectangular groove is opened at the upper end of the bearing plate base 35, and folded elastic blocks 36 are fixedly connected at equal intervals on the inner wall of the groove. Mounting rail 31 is used for mounting ball screw 32, which drives mounting socket 34 to move. The groove at the upper end of the bearing plate base 35 is used for placing the tray. When the operator performs a single feeding operation, the tray filled with electronic components is first clamped to the detachable bearing plate base 35. After the tray is placed, the elastic block 36 on the inner wall of the groove can clamp and fix the tray through the elastic force. Then, the bearing plate base 35 is connected to the conveying component. The bearing plate base 35 is inserted into the slot inside the mounting socket 34 through the bottom insertion rod 310. After the tray is installed, the ball screw 32 starts and drives the tray to move backward. The encoder assembly equipped with the ball screw 32 can monitor the speed of the two drive motors in real time and adjust them in real time to achieve speed synchronization, thereby realizing the synchronous movement of the mounting sockets 34 on the left and right sides.

[0024] The pallet conveying unit 3 also includes a telescopic short shaft 37, clamping blocks 38, and springs 39. Each mounting slot at the upper end of the mounting socket 34 has a set of clamping blocks 38 installed inside. The two sets of clamping blocks 38 located on the rear side are arranged horizontally, and the two sets of clamping blocks 38 located on the front side are arranged vertically. The upper end of the opposite side of each set of clamping blocks 38 has a chamfered structure. A telescopic short shaft 37 is fixedly connected to the back of each set of clamping blocks 38. The other end of the telescopic short shaft 37 is fixedly connected to the inner wall of the mounting slot. A spring 39 is sleeved on the outer side of each telescopic short shaft 37. The telescopic short shaft 37 is used for the installation of the clamping block 38 and the spring 39.

The two ends of the diagonal supports 6 are fixedly connected to the two ends of the right-angle brackets 5, respectively. The horizontal ends of the right-angle brackets 5 support the conveying channel 1, the mounting holes 7 in the vertical sections of the right-angle brackets 5 are used for bolt installation, thus fixing the right-angle brackets 5 to external equipment. The diagonal supports 6 improve the structural stability of the right-angle brackets 5.

[0026] It also includes ribs 8, which are also right-angled triangular structures and are snapped onto the inside of the right-angle end of the right-angle bracket 5. The two ends of ribs 8 are fixedly connected to the right-angle bracket 5 by hexagonal socket head cap screws. By snapping and fixing ribs 8 onto the inside of the right-angle end of the right-angle bracket 5, the load-bearing capacity of the right-angle bracket 5 can be improved.

[0027] The working principle of the pallet conveying device for a disc feeder provided by this utility model is as follows: This device is equipped with horizontal and vertical moving modules, which can effectively complete the conveying of pallets. It is also equipped with a gripper mechanism, which can realize the automatic picking, placing and returning of pallets. During feeding, the pallet conveying unit 3 conveys the pallet assembly from front to back. The mounting rail 31 is used for the installation of the ball screw 32. The ball screw 32 is used to drive the mounting socket 34 to move. The groove at the upper end of the bearing plate 35 is used for placing the pallet. After the pallet is installed, the ball screw 32 starts and drives the pallet to be conveyed backward. The encoder assembly equipped with the ball screw 32 can monitor the speed of the two drive motors in real time. The system provides real-time feedback and adjustments to achieve synchronized rotation speed, thereby enabling synchronized movement of the mounting sockets 34 on both sides. When the pallet moves to the end of the conveyor channel 1, the ball screw 41 drives the lifting pallet 43 to rise and fall. The lifting pallet 43 lifts the pallet upwards. When the pressure sensor 47 on the upper side detects contact with the bottom of the pallet assembly, each hydraulic cylinder 44 is activated, driving the gripper 45 to clamp onto the outer edge of the pallet assembly, thereby gripping the pallet assembly and achieving a locking effect to ensure stability during the lifting process. The encoder 410 is used to monitor the pressure value inside each hydraulic cylinder 44 in real time, thereby ensuring that the extension and retraction length of each hydraulic cylinder 44 rod is consistent, and ensuring a stable clamping effect of the gripper 45. This device can also effectively improve the automation level of the feeding process and adapt to the needs of high-speed placement machines: after feeding is completed, the lifting pallet 43 drives the pusher plate to descend, and the insertion rod 310 installed at the lower end of the lifting pallet 43 can be reset and inserted into the mounting socket 34 of the pallet conveying unit 3. When the pressure sensor 47 located on the lower side contacts the bottom of the mounting bracket 2, the four grippers 45 are released, thereby allowing the pallet conveying unit 3 to return the empty pallet outward; it also has a detachable carrier plate base 35 and an automatic clamping mechanism, so that the carrier plate base 35 with the pallet can be easily and conveniently installed. Connection with the conveying component: The groove at the upper end of the bearing plate seat 35 is used for placing the pallet. When the operator performs a single feeding operation, the pallet filled with electronic components is first clamped to the detachable bearing plate seat 35. After the pallet is placed, the elastic block 36 on the inner wall of the groove can clamp and fix the pallet through the elastic force. Then the bearing plate seat 35 is connected to the conveying component. The bearing plate seat 35 is inserted into the slot inside the mounting socket 34 through the bottom insertion rod 310. After the pallet is installed, the ball screw 32 starts and drives the pallet to be conveyed backward.Furthermore, the guide rod 48 and guide sleeve 49 cooperate to guide the lifting of the lifting pallet 43. The auxiliary limiting effect of the two guide rods 48 prevents the nut component and the lifting pallet 43 from rotating horizontally during the operation of the ball screw 41, ensuring stable lifting of the lifting pallet 43. The telescopic short shaft 37 is used for the installation of the clamping block 38 and the spring 39. The chamfered structure at the upper end of the clamping block 38 facilitates the insertion of the insertion rod 310. Under the action of the spring 39, each set of clamping blocks 38 clamps and fixes the insertion rod 310 at the lower end of the bearing plate seat 35, and the front and rear... The two sets of clamping blocks 38 are perpendicular to each other, which can clamp the insertion rod 310 in two directions, thereby preventing the bearing plate seat 35 from horizontal displacement and ensuring its installation stability; the horizontal end of the right-angle bracket 5 is used to support the conveying channel 1, and the mounting hole 7 of the vertical section of the right-angle bracket 5 is used for bolt installation, thereby fixing the right-angle bracket 5 to the external equipment; the diagonal support rod 6 can improve the structural stability of the right-angle bracket 5; and by fixing the rib 8 to the inside of the right-angle end of the right-angle bracket 5, the load-bearing capacity of the right-angle bracket 5 can be improved.
