Description

Technical Field

[0001] This application relates to the field of electronic device storage management, specifically to an electronic device tray loading device and system. Background Technology

[0002] In existing technologies, small plug-in electronic components such as capacitors and resistors, as well as SMT electronic components, are mainly packaged using trays. The electronic components are evenly spaced within a long strip of packaging film, which is then wound onto the tray. These trays are stored on warehouse shelves with multiple layers. Each shelf has a support rail for suspending the electronic component trays, and two or more trays can be arranged within a single support rail.

[0003] Furthermore, in existing technologies, conveyor belts are installed within the storage space for electronic components. When electronic component trays are loaded or unloaded, the conveyor belt transports the removed trays outside the storage space, or transports trays outside the storage space to the corresponding shelves, where they are then placed by a mechanical picking mechanism. These conveyor belts are large and occupy a significant amount of storage space. Moreover, for each tray loaded, the mechanical picking mechanism needs to reciprocate between the loading point and the storage location, resulting in low efficiency, especially when the distance between the storage location and the loading point is long, leading to even longer loading times. Summary of the Invention

[0004] In view of the above problems, this application provides an electronic component tray feeding device and system to solve the technical problem of low electronic component tray feeding efficiency.

[0005] To achieve the above objectives, the inventors provide an electronic component tray loading device, which is located at one end of an electronic component storage space, wherein the storage space is provided with two or more shelves for storing electronic component trays.

[0006] The electronic device tray loading device includes: a first conveying mechanism, a second conveying mechanism, and a material frame exchange mechanism. The first conveying mechanism is close to the storage space, the second conveying mechanism is far away from the storage space relative to the first conveying mechanism, and the material frame exchange mechanism is connected to the first conveying mechanism and the second conveying mechanism respectively.

[0007] The material frame exchange mechanism includes an inlet end and an outlet end. The first conveying mechanism is used to transfer the first material frame containing the electronic device tray to the inlet end, and then to the second conveying mechanism by the material frame exchange mechanism.

[0008] The second conveying mechanism is used to convey the first material frame to the storage space and to convey the second material frame removed from the storage space to the infeed end. The material frame exchange mechanism conveys the second material frame to the discharge end and transfers it to the first conveying mechanism.

[0009] In some technical solutions, the electronic device tray loading device further includes a loading platform and a loading gripper;

[0010] The loading platform is used to place the material string to be loaded, which is formed by stacking multiple electronic device trays in a vertical direction; the loading gripper slides along the horizontal beam to grab the electronic device trays on the loading platform and place them into the second material frame on the first conveying mechanism.

[0011] In some technical solutions, the loading gripper includes two or more gripper blades and a gripper blade driving device. The gripper blades include a protrusion for inserting into a central hole in the middle of the electronic device tray. The gripper blade driving device is used to drive the gripper blades to spread outward to clamp the electronic device tray.

[0012] In some technical solutions, the electronic component tray loading device further includes an identification device, which is used to identify the information of the electronic component tray;

[0013] The electronic device tray that has passed the identification process is picked up by the feeding gripper and placed into the second material frame on the first conveying mechanism.

[0014] In some technical solutions, the electronic component tray loading device further includes a tray placement platform, and the identification device identifies the electronic component trays that fail to pass and places them on the tray placement platform for removal.

[0015] In some technical solutions, the first conveying mechanism and the material frame exchange mechanism are arranged horizontally side by side, end to end, and the second conveying mechanism is located at the feeding end; the first conveying mechanism, the second conveying mechanism, and the material frame exchange mechanism are all provided with two or more conveying rollers or conveying wheels that drive the material frame to convey.

[0016] In some technical solutions, the first conveying mechanism is provided with a first lifting mechanism, the second conveying mechanism is provided with a second lifting mechanism, the material frame exchange mechanism is provided with a third lifting mechanism at the inlet end and a fourth lifting mechanism at the outlet end. The first lifting mechanism is used to lift and transfer the first material frame into the inlet end, the second lifting mechanism is used to lift and transfer the second material frame into the inlet end, the third lifting mechanism is used to lift and transfer the first material frame to the second conveying mechanism, and the fourth lifting mechanism is used to lift and transfer the second material frame to the first conveying mechanism.

[0017] To solve the above-mentioned technical problems, the present invention also provides another technical solution:

[0018] An electronic component tray loading system includes a loading device and a tray picking and placing device. The loading device is the electronic component tray loading device described in any of the above technical solutions. The tray picking and placing device is movable and installed in the storage space of the electronic components for placing the electronic component trays on the shelves.

[0019] The material tray picking and placing device is equipped with a material frame mechanism, and the material frame mechanism is equipped with a material frame picking and placing cylinder. The material frame picking and placing cylinder can transfer the first material frame on the feeding device to the material frame mechanism, and transfer the second material frame on the material frame mechanism to the feeding device.

[0020] In some technical solutions, the material frame pick-and-place cylinder is equipped with a platform for supporting the first material frame or the second material frame; the material frame pick-and-place cylinder drives the platform and the first material frame or the second material frame to descend vertically, so that the second material frame leaves the platform and is transferred to the loading device;

[0021] Alternatively, the material frame pick-and-place cylinder drives the platform to rise, so that the first material frame placed on the loading device is transferred to the platform.

[0022] In some technical solutions, the tray handling device also includes a tray gripper, which is used to place electronic component trays in the tray mechanism onto the shelf, or to place electronic component trays on the shelf onto the tray mechanism.

[0023] Unlike existing technologies, the above-mentioned electronic device tray loading device includes a first conveying mechanism, a second conveying mechanism, and a tray exchange mechanism. These mechanisms transport a first tray containing multiple stacked trays to the storage space for loading by the tray loading and unloading device. Furthermore, a second tray, after being loaded onto the shelf, can be transferred out for reuse. Therefore, this loading device improves the loading efficiency of the tray loading and unloading device. The tray loading and unloading device also includes a tray mechanism that can simultaneously carry multiple trays to different shelves for loading, reducing the number of round trips and the travel distance of the tray loading and unloading device, thereby further improving loading efficiency. Moreover, this invention eliminates the need for a tray conveyor belt within the storage space, improving the space utilization rate of the storage area.

[0053] Please see Figures 1 to 7 This embodiment provides an electronic component tray loading device and system. This electronic component tray loading device and system can be applied to scenarios requiring the storage and loading of electronic component trays by various electronic equipment manufacturers, electronic component manufacturers, or distributors. Figure 1 As shown, the storage space 1 is equipped with shelves 11, and the shelves have storage positions 111 for placing electronic component trays. The electronic components can be resistors, capacitors, transistors, diodes, and other electronic devices, and can be SMT (surface mount technology) packaged or through-hole packaged. The electronic component trays can be of different sizes, such as 7-inch, 13-inch, and 15-inch. The electronic component tray loading device 3 is used to transport external electronic component trays in a series via a tray frame to one end of the storage space (i.e., the loading end), and then the tray frame is handed over to the tray loading device 2, which loads the electronic component trays 4 into storage positions 111 on each shelf.

[0054] like Figure 1 and Figure 2 As shown, in this embodiment, an electronic component tray loading device 3 is disposed at one end of an electronic component storage space 1. The storage space 1 is provided with two or more shelves 11 for storing electronic component trays. The electronic component tray loading device 3 includes: a first conveying mechanism 31, a second conveying mechanism 32, and a tray exchange mechanism 33. The first conveying mechanism 31 is close to the storage space 1, and the second conveying mechanism 32 is away from the storage space 1 relative to the first conveying mechanism 31. The tray exchange mechanism 33 is connected to the first conveying mechanism 31 and the second conveying mechanism 32 respectively.

[0055] The material frame exchange mechanism 33 includes an inlet end and an outlet end. The first conveying mechanism 31 is used to transfer the first material frame containing the electronic device tray to the inlet end, and then the material frame exchange mechanism 33 transfers it to the second conveying mechanism 32. The second conveying mechanism 32 is used to convey the first material frame to the storage space 1, and to convey the second material frame removed from the storage space 1 to the inlet end. The material frame exchange mechanism 33 conveys the second material frame to the outlet end and transfers it to the first conveying mechanism 31.

[0056] like Figure 2 , Figure 3 and Figure 4 As shown, the feeding end of the material frame exchange mechanism 33 is the fifth position A5, which is close to the storage space 1. The discharging end of the material frame exchange mechanism 33 is the second position A2, which is far away from the storage space 1 relative to the feeding end.

[0057] In this embodiment, the first material frame with multiple stacked material trays can be conveyed to the storage space for the material tray picking and placing device to be placed on the shelf through the first conveying mechanism 31, the second conveying mechanism 32 and the material frame exchange mechanism 33. The second material frame after being placed on the shelf by the material tray picking and placing device can be transferred out for reuse. Therefore, the feeding device can improve the feeding efficiency of the material tray picking and placing device.

[0058] like Figure 2 and Figure 3 As shown, in some technical solutions, the electronic component tray loading device further includes a loading platform 34 and a loading gripper 35; the loading platform 34 is used to place the material strings to be loaded, the material strings being formed by stacking multiple electronic component trays 4 vertically; the loading gripper 35 slides along a horizontal beam 351, and the loading gripper 35 is used to grab the electronic component trays on the loading platform 34 into the second material frame on the first conveying mechanism 31, so that the electronic component trays are stacked in the second material frame.

[0059] It should be noted that the structures of the first and second material frames are identical, such as... Figure 7 As shown, both the first and second material frames include a base and guide posts 2334 on the base. In this embodiment, the use of a first and a second material frame is solely for better differentiation of whether a material frame 2333 contains a tray, and whether the material frame is being transferred from the outside into the storage space for loading, or from the storage space outwards. In this embodiment, the material frame transferred from the outside into the storage space 1 is called the first material frame, which typically contains multiple electronic component trays. The material frame transferred outwards from the storage space 1 is called the second material frame, which is typically empty. During the cyclic loading process, the first and second material frames can be switched.

[0060] like Figure 4 As shown, in some embodiments, the first conveying mechanism 31 and the material frame exchange mechanism 33 are arranged horizontally side by side, end to end, and the second conveying mechanism 32 is arranged at the feeding end; the first conveying mechanism 31, the second conveying mechanism 32 and the material frame exchange mechanism 33 are all provided with two or more conveying rollers or conveying wheels that drive the material frame to convey.

[0061] In some embodiments, the first conveying mechanism 31 is provided with a first lifting mechanism, the second conveying mechanism 32 is provided with a second lifting mechanism, the material frame exchange mechanism 33 is provided with a third lifting mechanism at the inlet end and a fourth lifting mechanism at the outlet end. The first lifting mechanism is used to lift and transfer the first material frame into the inlet end, the second lifting mechanism is used to lift and transfer the second material frame into the inlet end, the third lifting mechanism is used to lift and transfer the first material frame to the second conveying mechanism, and the fourth lifting mechanism is used to lift and transfer the second material frame to the first conveying mechanism.

[0062] In some embodiments, the electronic component tray loading device 3 further includes an identification device for identifying information about the electronic component tray; the identified electronic component tray is grasped by the loading gripper and placed into the second material frame on the first conveying mechanism. The identification device can be positioned above the loading platform 34, and the electronic component tray is lifted to a certain height by a lifting device for barcode scanning.

[0063] In some embodiments, a barcode or QR code is provided on the electronic component tray, and the identification device can be a photo scanning device. Alternatively, in some embodiments, other labels are provided on the electronic component tray, and the identification device is a scanning device corresponding to that label.

[0064] In some embodiments, the electronic component tray loading device further includes a tray placement platform, and the identification device identifies failed electronic component trays and places them on the tray placement platform for removal.

[0065] In the above embodiment, in the electronic component tray loading device 3, the electronic component trays 4 to be loaded are stacked to form a loading string, which is placed at the first position A1 of the loading platform 34, and loaded from the first position A1. After positioning, the electronic component tray 4 is lifted by a servo to a certain height. The identification device above the first position A1 performs identification (e.g., camera photo scanning identification). The loading gripper 35 grabs the electronic component tray. The tray with incorrect identification result is placed on the tray placement platform 36 above the second position A2 for manual removal. The electronic component tray with successful identification is grabbed by the loading gripper and stacked in the first material frame at the third position A3 on the first conveying mechanism 31. The full first material frame is conveyed by the small roller below to the fourth position A4 to wait for exchange with the second material frame on the tray picking and placing device.

[0066] The material frame exchange process is as follows: The material tray picking and placing device 2 in the storage space 1 moves to the sixth position A6 on the second conveying mechanism and lowers the second material frame it carries to the sixth position A6. The lifting mechanism below the sixth position A6 lifts and transports the second material frame to the material frame exchange mechanism inlet end, i.e., the fifth position A5. It is then conveyed to the second position A2 by the roller on the material frame exchange mechanism. The electronic device material tray loading device 3 determines whether the third position A3 is vacant. If so, the lifting mechanism below can transport it to the third position A3 for loading the material frame. At this time, the lifting mechanism below the fourth position A4 lifts the second material frame and moves it to the fifth position A5. The lifting mechanism below the fifth position A5 lifts and transports it to the sixth position A6. The material frame mechanism of the material tray picking and placing device 2 lifts the material frame to complete the material frame exchange operation.

[0067] In some technical solutions, the loading gripper includes two or more gripper blades and a gripper blade driving device. The gripper blades include a protrusion for inserting into a central hole in the middle of the electronic device tray. The gripper blade driving device is used to drive the gripper blades to spread outward to clamp the electronic device tray.

[0068] The electronic component tray is circular and includes two opposing panels. A groove between the two panels is used to wind the electronic component. A central hole is provided in the middle of the panels to securely connect the two panels. In the above embodiment, the gripper of the loading hand can be an insertable gripper, which includes multiple claw pieces that can converge towards the center and expand outwards. The gripper is inserted into the central hole and expands outwards to hold the tray. In other embodiments, the gripper of the loading hand can also be a suction cup gripper, or a clamping body similar to the above-described clamping mechanism. In this embodiment, the gripper of the loading hand uses an insertable gripper, which can reduce the size of the gripper and improve the stability of the tray clamping.

[0069] To solve the above-mentioned technical problems, the present invention also provides another technical solution:

[0070] like Figure 1 As shown, an electronic component tray loading system includes a loading device and a tray picking and placing device 2. The loading device is the electronic component tray loading device 3 described in any of the above technical solutions. The tray picking and placing device 2 is mobilely installed within the electronic component storage space 1 and is used to place electronic component trays on shelves 11. A traveling track 113 is provided on the floor of the storage space for the tray picking and placing device 2 to travel on.

[0071] The material tray picking and placing device 2 is provided with a material frame mechanism 233, and the material frame mechanism 233 is provided with a material frame picking and placing cylinder 2336. The material frame picking and placing cylinder 2336 can transfer the first material frame on the feeding device 3 to the material frame mechanism, and transfer the second material frame on the material frame mechanism to the feeding device 3.

[0072] In some embodiments, the material frame pick-and-place cylinder 2336 is provided with a platform 2337 for supporting the first material frame or the second material frame; the material frame pick-and-place cylinder 2336 drives the platform 2337 and the first material frame or the second material frame to descend vertically, so that the second material frame leaves the platform and is transferred to the loading device.

[0073] Alternatively, the material frame pick-and-place cylinder drives the platform to rise, so that the first material frame placed on the loading device is transferred to the platform.

[0074] like Figure 5 and Figure 6 As shown, in some embodiments, the tray handling device 2 further includes a tray gripper 232, which is used to place electronic component trays in the tray mechanism onto the shelf, or to place electronic component trays on the shelf onto the tray mechanism.

[0075] The base 21 of the tray loading and unloading device 2 is equipped with a traveling mechanism 211 and a support 22. A lifting rail 221 is mounted on the support 22. The lifting vehicle 23 is connected to the lifting rail 221 and can be driven to move up and down along the lifting rail by a lifting drive device 222. The lifting vehicle 23 and the lifting drive device 222 can be connected by gears, racks, belts, chains, or other transmission methods. The lifting drive device 222 can be a servo motor drive, a lifting cylinder drive, etc.

[0076] When it is necessary to retrieve the electronic component tray on the tray 112, the tray retrieval and placement device 2 first pulls the tray 112 out of the storage position along the depth direction using the tray gripper 231, and then retrieves the electronic component tray from the storage slot 1121 using the tray gripper 232, and then places the retrieved electronic component tray into the material frame mechanism 233.

[0077] like Figure 5 and Figure 6 As shown, the material frame mechanism 233 includes a material frame 2333, which includes a base plate and multiple guide posts 2334 disposed on the base plate; the multiple guide posts 2334 are distributed along the same circumference and cooperate with the base plate to form a space that constrains the electronic device trays to be stacked vertically.

[0078] The material frame pick-and-place cylinder 2336 can be two in number, symmetrically arranged on the lifting unit. The space between the two cylinders is used to accommodate the material frame 2333 and the platform 2337. Figure 6As shown, the platform 2337 is a hollow platform, comprising four support points. The middle portion of each support point is hollow, and the four support points correspond to the four corners of the base. Two of the four support points are mounted on one of the material frame pick-and-place cylinders 2336, and the other two support points are mounted on the other material frame pick-and-place cylinder. When the material frame pick-and-place cylinder 2336 drives the platform and the material frame to descend, the platform can pass through the gap of the second conveying mechanism 32 on the material tray loading device 3, causing the material frame 2333 to be transferred to the sixth position A6 of the second conveying mechanism 32.

[0079] When the material frame pick-and-place cylinder 2336 drives the platform and the material frame to rise, the platform can rise from below the second conveying mechanism 32 on the material tray loading device 3 and transfer the material frame placed on the conveying platform to the platform.

[0080] In this embodiment, the tray picking and placing device 2 can carry multiple electronic component trays and move them within the storage space via the material frame mechanism 233. When discharging, it can grab multiple electronic component trays and temporarily place them in the material frame mechanism, then carry multiple electronic component trays at once to the discharge end of the storage space 1 for discharge. When feeding electronic component trays, the tray picking and placing device 2 can carry multiple trays at once to the corresponding shelf for feeding via the material frame mechanism. Therefore, the material frame mechanism can greatly reduce the number of times the tray picking and placing device 2 travels back and forth within the storage space during feeding and unloading, thus improving the efficiency of tray feeding and unloading.

[0081] like Figure 5 and Figure 6 As shown, in one embodiment, the material frame mechanism 233 further includes a top material mechanism 2331; a hollow part 2335 is provided in the middle of the base plate, and the top material mechanism 2331 can pass through the hollow part 2335 to lift the electronic device tray upward.

[0082] The hollowed-out portion 2335 is a U-shaped groove; the top material mechanism 2331 includes a slider 2332 and an upper top plate disposed on the slider. The slider 2332 is disposed on the lifting vehicle 23 via a slide rail. The upper top plate is disposed on the slider 2332. The slider 2332 drives the upper top plate to pass through the hollowed-out portion 2335 and lift the electronic device tray upward.

[0083] The slider 2332 can be driven by a servo motor to slide vertically. During the process of placing the electronic component trays in the material frame mechanism onto the shelf, the top material mechanism 2331 can lift the trays upwards, and then the tray gripper 232 picks up the trays and places them onto the pallet 112 of the shelf 11 storage location. Then, the process is repeated until all the trays in the material frame are placed onto their corresponding pallets.

[0084] When placing the electronic component tray from pallet 112 on the shelf into the material frame, the upper plate of the top-feeding mechanism can be raised to the height of the tray gripper 232. The tray, lowered by the tray gripper 232, is supported by the upper plate. Then, the upper plate is lowered to ensure the electronic component tray is stably placed into the material frame. In this embodiment, the cooperation between the top-feeding mechanism and the tray gripper enhances the stability of removing or placing the tray from the material frame.

[0085] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
