Description

Technical Field

[0001] This utility model relates to the field of electronic component processing technology, and in particular to a sorting structure for electronic component processing. Background Technology

[0002] Electronic component fabrication refers to the process of transforming various basic electronic materials into electronic components with specific functions through a series of technological processes. It encompasses everything from raw material preparation, such as cutting and shaping materials like metals, plastics, and ceramics, to the precision machining of components.

[0003] In the later stages of electronic component processing, the finished components need to be sorted. A two-dimensional linear motion mechanism drives a negative pressure assembly to move precisely along the X and Y axes in a plane, ensuring the negative pressure nozzle accurately reaches the location of the electronic component. Once activated, the negative pressure assembly generates negative pressure to attract the electronic component, moving it to the inside of the testing equipment. The testing equipment then checks various parameters of the component, such as dimensions and electrical performance. Based on the test results, the two-dimensional linear motion mechanism moves again, transporting the component to a tray in the corresponding sorting area, thus completing the entire testing and sorting process. Each tray has a capacity limit, and the number of components is monitored in real time by a controller. Once a tray is full, the controller triggers a signal, and the conveyor belt immediately starts, transporting the full tray to the next assembly process. Simultaneously, the system schedules a robotic arm to automatically grab an empty tray and place it back into its original sorting area.

[0004] The shortcomings of the existing technical solutions are: the conveyor belt has a speed limit, and it takes time for the pallets to be completely removed from the sorting area. Meanwhile, the robotic arm must wait until the fully loaded pallets have been completely removed before it can operate. This waiting process creates idle periods for the equipment, slowing down the overall production pace and reducing sorting efficiency. Utility Model Content

[0005] This invention provides a sorting structure for electronic component processing, which can solve the problem in the prior art where, when a conveyor belt is transporting a fully loaded pallet, the robotic arm must wait until the fully loaded pallet has been completely removed before it can operate, thus reducing sorting efficiency.

[0006] A sorting structure for electronic component processing includes a feeding platform. A two-dimensional linear motion mechanism is arranged above the feeding platform. An electric telescopic device is provided at the output end of the two-dimensional linear motion mechanism. A vacuum nozzle is fixedly provided at the end of the electric telescopic device. An electronic component testing device is arranged at the rear of the feeding platform. Multiple sets of conveying devices for conveying pallets are arranged parallel to the rear of the feeding platform. Each set of conveying devices has a lifting platform for supporting the pallets at one end near the feeding platform. Each set of conveying devices has a pallet lifting mechanism for lifting the pallets to the receiving position fixedly provided at one end near the feeding platform. The pallet lifting mechanism is located above the lifting platform.

[0007] As a further embodiment of this utility model: each set of pallet lifting mechanisms includes an outer frame fixedly connected to the end of the conveying device, and conveyor belt assemblies are longitudinally distributed on both sides inside the outer frame. The conveyor belt assembly includes a conveyor belt and a driving component for driving the conveyor belt to move. Multiple sets of pallets are fixedly arranged at equal intervals on the surface of the conveyor belt.

[0008] As a further embodiment of this utility model, the upper surface of the lifting platform is provided with a positioning groove for placing the pallet assembly.

[0009] As a further embodiment of this utility model: both the electric telescopic device and the vacuum nozzle are provided in two sets, and each set of vacuum nozzles is configured to be installed on the output end of the corresponding electric telescopic device.

[0010] As a further embodiment of this utility model: a laser sensor for detecting the position of the tray is fixedly installed on the front side of the outer frame.

[0011] As a further embodiment of this utility model: a housing for protecting the two-dimensional linear motion mechanism and the feeding platform is fixedly provided on the outside of the feeding platform.

[0012] As a further embodiment of this utility model, the front, rear, left, and right sides of the outer casing are all provided with closed doors.

[0013] As a further embodiment of this utility model, the electronic component testing device is arranged in multiple groups horizontally.

[0014] As a further embodiment of this utility model: a gantry support is provided on the inner side of the outer shell, and the two-dimensional linear motion mechanism is disposed on the gantry support.

[0015] As a further embodiment of this utility model: the two-dimensional linear motion mechanism includes longitudinal guide rails that are fixedly connected to the gantry bracket and distributed in the front and rear, and transverse guide rails that are distributed in the transverse direction and are arranged in conjunction with the longitudinal guide rails. Electric sliders are arranged in conjunction with the transverse guide rails, and both sets of electric telescopic devices are located on the electric sliders.

[0016] The beneficial effects of this utility model are: 1. In use, when the equipment is started, the lifting platform raises the pallet upwards. The laser sensor accurately detects the position and sends a signal, causing the lifting platform to stop in time. The pallet plates of the conveyor belt assemblies on both sides of the pallet lifting mechanism can support the pallet ear plates respectively, realizing the precise lifting of individual pallets. When the top pallet on the conveyor belt assembly is full, the two-dimensional linear motion mechanism drives the electric telescopic device to push the full pallet from the top of the pallet lifting mechanism to the conveying device. The conveying device outputs the pallet outwards, and the pallet lifting mechanism 6 quickly replenishes the next set of empty pallets. Each time an empty pallet is replenished, the top pallet on the top of the lifting platform is simultaneously taken away, forming a circular conveying. This coordination avoids the situation where the robotic arm waits for the full pallet to be removed, allowing empty pallets to be replenished in time, thus improving the overall sorting efficiency.

[0017] 2. In use, when a set of electronic component testing devices detects a quality issue, the two-dimensional linear motion mechanism drives two sets of vacuum nozzles to work in tandem. The electric telescopic device first causes the latter set of vacuum nozzles to pick up the component to be tested, while the former set picks up components that have already been tested. Then, the latter set of vacuum nozzles delivers new components for testing, while the former set sorts the tested components to their corresponding trays. The entire process involves the two sets of vacuum nozzles working alternately, making full use of equipment operating time, reducing idle waiting time, and improving overall production efficiency.

[0020] The specific embodiments of this utility model are described in detail below, but it should be understood that the scope of protection of this utility model is not limited to the specific embodiments.

[0021] like Figures 1 to 4 As shown in the figure, this utility model provides a sorting structure for electronic component processing, including a feeding platform 4. Multiple sets of trays are neatly placed on the feeding platform 4, and the positions of the trays are fixed, ensuring that each set of electronic components to be inspected is in a designated position for subsequent precise sorting. A two-dimensional linear motion mechanism 1 is provided above the feeding platform 4. Specifically, the two-dimensional linear motion mechanism 1 includes longitudinal guide rails fixedly connected to a gantry bracket 10 and distributed front-to-back, and transverse guide rails distributed laterally on the longitudinal guide rails. An electric slider is mounted on the transverse guide rails. The longitudinal guide rails control movement in the Y direction, and the transverse guide rails control movement in the X direction. This design allows the working area of ​​the electric slider to achieve full coverage on the feeding platform 4. An electric telescopic device 2 is mounted on the electric slider, and a vacuum nozzle 3 is fixedly mounted at the end of the electric telescopic device 2. The main function of the vacuum nozzle 3 is to adsorb electronic components, thereby realizing the gripping and placement of electronic components. An electronic component testing device 5 is installed on the rear side of the feeding platform 4 to test the quality of electronic components.

[0022] Multiple sets of conveying devices 7 for conveying pallets are arranged parallel to each other on the rear side of the unloading platform 4, such as... Figure 2 As shown, the conveyor device 7 is a double-track conveyor belt. Each conveyor device 7 has a lifting platform 8 for supporting pallets at one end near the unloading platform 4. Simultaneously, each conveyor device 7 also has a pallet lifting mechanism 6 fixedly installed at one end near the unloading platform 4 to lift the pallets to the receiving position, and the pallet lifting mechanism 6 is located above the lifting platform 8. The lower end of the electric telescopic device 2 has the function of pushing the pallets from the upper end of the pallet lifting mechanism 6 onto the conveyor device 7. In actual operation, when the pallet is full, the two-dimensional linear motion mechanism 1 drives the electric telescopic device 2 to push the pallets above the pallet lifting mechanism 6 onto the conveyor device 7. The lifting platform 8 is responsible for delivering the pallets to the bottom of the pallet lifting mechanism 6, which then lifts the pallets to a certain height to the sorting area. This operation process enables rapid pallet replenishment, avoids wasting time waiting for pallets to be moved out, and improves sorting efficiency.

[0023] Specifically, each pallet lifting mechanism 6 includes an outer frame 601 fixedly connected to the end of the conveying device 7. Conveyor belt assemblies 602 are longitudinally distributed on both sides of the inner side of the outer frame 601. Each conveyor belt assembly 602 includes a conveyor belt and a drive unit for moving the conveyor belt. Multiple sets of pallets 603 are equidistantly fixed on the surface of the conveyor belt. Each pallet has ear plates extending to both sides, and the pallets 603 on the conveyor belts on both sides support the ear plates on both sides of the pallet. During operation, the conveyor belts on both sides simultaneously drive the pallets 603 on the surface to move, thereby slowly lifting the pallet and completing the replenishment of empty pallets.

[0024] The upper surface of the lifting platform 8 has positioning slots for placing pallet sets, the shape of which matches the bottom shape of the pallet. During operation, multiple pallets are stacked together, and the bottom pallet is placed in the positioning slot. The positioning slots ensure that the pallets do not shift, guaranteeing stability during transport. Furthermore, pads are installed on both sides inside the pallet. When two pallets are stacked, their ear plates separate, preventing adjacent pallets from nesting and facilitating the separation of adjacent pallets by the pallet plate 603, enabling precise lifting of individual pallets.

[0025] Multiple sets of laser sensors 604 for detecting the position of the pallet are fixedly installed on the front side of the outer frame 601. When the lifting platform 8 raises the uppermost pallet to the position corresponding to the laser sensor 604, the laser sensor 604 will send a signal, and the lifting platform 8 will stop moving after receiving the signal. At this time, the pallet 603 on the conveyor belt assembly 602 starts to move, which can lift the uppermost pallet, thereby realizing a precise feeding operation and ensuring that the pallet can be lifted and transported accurately.

[0026] In one specific embodiment, a housing 9 is fixedly installed on the outer side of the unloading platform 4 to protect the two-dimensional linear motion mechanism 1 and the unloading platform 4. The housing 9 has closed doors on its front, rear, left, and right sides. The front closed door is mainly used to place a tray full of electronic components to be tested; while the rear, left, and right closed doors are mainly used for device maintenance and also facilitate the placement of empty trays on the lifting platform 8 by workers. During the preparation phase, workers place a certain number of empty trays on the lifting platform 8, and the conveyor belt assembly 602 lifts the empty trays sequentially until the support positions on the conveyor belt assembly 602 are full. Then, the lifting platform 8 is driven to retract, thus making room for adding more empty trays and maximizing the number of empty trays stored. Each time the conveyor belt assembly 602 moves to replenish a group of empty trays at the top, it simultaneously carries away the topmost tray on the top of the lifting platform 8 to the bottommost storage position between the conveyor belt assembly 602 and the topmost storage position. Through this cyclical operation, a continuous conveying effect is achieved, ensuring that empty trays are supplied efficiently and promptly.

[0027] In another specific embodiment, both the electric telescopic device 2 and the vacuum nozzles 3 are provided in two sets, with each set of vacuum nozzles 3 positioned on the output end of the corresponding electric telescopic device 2. When a set of electronic component testing devices 5 detects the quality of an electronic component, the two-dimensional linear motion mechanism 1 can drive the two sets of vacuum nozzles 3 to move. During the movement, the electric telescopic device 2 first causes the latter set of vacuum nozzles 3 to adsorb a set of electronic components to be tested. Then, the two-dimensional linear motion mechanism 1 drives the former set of vacuum nozzles 3 to move above the set of electronic component testing devices 5, adsorbing the electronic components that have already been tested on the electronic component testing devices 5. Next, it drives the latter set of vacuum nozzles 3 to align with the electronic component testing devices 5, sending the adsorbed set of electronic components to be tested into the electronic component testing devices 5 for testing. Finally, the two-dimensional linear motion mechanism 1 sends the electronic components on the former set of vacuum nozzles 3 to the tray corresponding to the quality, and the electric telescopic device 2 extends to send the electronic components to a fixed position, completing the sorting operation of the electronic components. This dual vacuum nozzle design can further improve sorting efficiency and reduce operation time.

[0028] Working Principle: The operator opens the closed door on the rear, left, or right side of the outer casing 9, stacks a certain number of empty pallets together, and then places the bottom pallet into the positioning slot on the upper surface of the lifting platform 8. The equipment is started, and the lifting platform 8 lifts the pallets it carries upwards. Each time the top pallet is lifted to the position corresponding to the laser sensor 604 on the front side of the outer frame 601, the laser sensor 604 sends a signal, and the lifting platform 8 stops moving. The pallet plates 603 on the conveyor belt assemblies 602 on both sides of the pallet lifting mechanism 6 begin to move, supporting the ear plates on both sides of the pallet and slowly lifting the pallet, thus lifting the empty pallets one by one. As the support positions on the conveyor belt assembly 602 gradually fill with empty pallets, the lifting platform 8 retracts, making room for the addition of more empty pallets, maximizing the number of empty pallets stored.

[0029] The operator opens the front closed door of the outer casing 9 and places the tray full of electronic components to be tested on the loading platform 4. The two-dimensional linear motion mechanism 1 starts working, driving the electric slider to move to the appropriate position above the loading platform 4. The electric telescopic device 2 extends, causing the vacuum nozzle 3 at the end to descend and pick up the electronic components to be tested. The two-dimensional linear motion mechanism 1 moves the vacuum nozzle 3 with the electronic components to be picked up above the electronic component testing device 5, and feeds the electronic components into the testing device in sequence for quality inspection.

[0030] After the inspection is completed, according to the quality of the electronic components, the two-dimensional linear motion mechanism 1 drives the vacuum nozzle 3 to move above the tray of the corresponding quality, and the electric telescopic device 2 extends to place the electronic components in a fixed position, completing one sorting operation.

[0031] When a pallet is full, the two-dimensional linear motion mechanism 1 drives the electric telescopic device 2 to push the full pallet from the top of the pallet lifting mechanism 6 onto the conveyor device 7. The conveyor device 7 outputs the pallet outward, and the pallet lifting mechanism 6 quickly replenishes the next set of empty pallets. At the same time, each time the conveyor belt assembly 602 moves to replenish a set of empty pallets to the top, it simultaneously carries away the topmost pallet on the lifting platform 8 to the bottommost storage position between the conveyor belt assembly 602, completing continuous conveying.

[0032] In the embodiment of the dual vacuum nozzle 3, when a set of electronic component testing devices 5 detects the quality of electronic components, the two-dimensional linear motion mechanism 1 drives the two sets of vacuum nozzles 3 to move. The electric telescopic device 2 first causes the latter set of vacuum nozzles 3 to adsorb a set of electronic components to be tested. Then, it moves the former set of vacuum nozzles 3 above the set of electronic component testing devices 5, adsorbing the electronic components that have already been tested on the electronic component testing devices 5. Then, it drives the latter set of vacuum nozzles 3 to align with the electronic component testing devices 5, sending the adsorbed set of electronic components to be tested into the electronic component testing devices 5 for testing. Finally, the two-dimensional linear motion mechanism 1 sends the electronic components on the former set of vacuum nozzles 3 to the tray corresponding to the quality, and the electric telescopic device 2 extends to send the electronic components to a fixed position, completing the sorting operation of the electronic components. This embodiment of the dual vacuum nozzle 3 reduces operation waiting time and further improves sorting efficiency.

[0033] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
