Abstract
Description
A parts picking operation navigation system Technical Field
[0001] This utility model relates to the field of material quality inspection and control, and in particular to a parts picking operation navigation system. Background Technology
[0002] In the industrial manufacturing and warehousing logistics sectors, existing parts picking systems typically employ an indicator light-based operating mode. This involves configuring indicator lights on each storage unit of the shelf, and controlling the illumination of these lights to direct operators to pick the target parts from the corresponding storage unit. During this process, operators must visually identify the illuminated storage unit, move to the corresponding unit, grab the part, and press the light to turn it off, thus marking the retrieved part. This method not only carries the risk of mispicking due to reliance on manual visual judgment but also fails to provide part picking path planning, resulting in low picking efficiency. Furthermore, the additional manual step of pressing the light to turn it off adds unnecessary operations and affects the overall operational smoothness. Summary of the Invention
[0003] The purpose of this invention is to propose a parts picking operation navigation system to solve one or more technical problems existing in the background art.
[0004] To achieve this objective, the present invention adopts the following technical solution:
[0005] A parts picking operation navigation system includes a shelf, multiple identification modules, identification wristbands, and a control module. The shelf has multiple storage units. The identification modules are respectively located on the front of the storage units. Each identification unit includes a directional reader and a status indicator light. The reading range of the directional reader covers the front of the storage unit, forming an identification plane. The identification wristband has a built-in RFID tag with a unique ID. The directional reader and the status indicator light are both connected to the control module, and both are connected to a WMS system through the control module. When the identification wristband passes through the identification plane, the directional reader reads the ID information of the RFID tag.
[0006] Preferably, the system also includes a lighting controller, with multiple status indicator lights connected to the lighting controller, which is connected to the control module.
[0007] Preferably, the status indicator light has two indication states.
[0008] Preferably, the identification unit further includes a buzzer, which is connected to the control module.
[0009] Preferably, the shelf includes multiple sets of shelves and support frames, with the multiple sets of shelves arranged alternately on the support frames, and the identification unit fixed alternately on the front side of the shelves.
[0010] Preferably, the shelf further includes multiple storage boxes, which are arranged on the shelf to form multiple storage units, and each storage box corresponds to one of the identification units.
[0011] Preferably, the identification module further includes an information display surface, and the status indicator light is located on one side of the information display surface.
[0012] Preferably, it also includes a display device, which is connected to the control module and is located on the shelf.
[0013] The beneficial effects of this invention are as follows: By placing the directional reader / writer on the front side of the storage unit of the shelf and forming an identification plane, when an operator wearing an identification wristband reaches into the storage unit to retrieve an item, the directional reader / writer corresponding to the storage unit can verify the ID information of the identification wristband, thereby recording each retrieval action of the operator. This achieves identification and management of the operator, retrieval time, and retrieved item. After recording, the status indicator light can be automatically turned off, reducing redundant actions and improving work efficiency. Furthermore, it can promptly remind operators of any mis-picking, ensuring correct retrieval operations. Compared to traditional picking systems that rely solely on visual judgment, this invention effectively avoids mis-picking by combining the indication of the status indicator light with the reading and writing of the identification wristband by the directional reader / writer. It transforms the operation from one based on human subjective or experience-based judgment into an environment with system prompts and error prevention, reducing the reliance on skilled personnel in the work position and expanding the company's flexible employment opportunities.

[0016] Figure 2 is a structural schematic diagram of a shelf according to one embodiment of the present invention.
[0017] The components include: shelf 1, storage unit 111, identification module 2, identification wristband 3, control module 4, directional reader 21, identification plane 211, status indicator light 22, shelf 11, support frame 12, storage box 13, information display surface 23, display device 5, and WMS system 6. Detailed Implementation
[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0019] This embodiment of a parts picking operation navigation system, referring to Figure 1, includes a shelf 1, multiple identification modules 2, identification wristbands 3, and a control module 4. The shelf 1 has multiple storage units 111. The identification modules 2 are respectively located on the front side of the multiple storage units 111. Each identification unit includes a directional reader 21 and a status indicator light 22. The reading / writing range of the directional reader 21 covers the front side of the storage unit 111, forming an identification plane 211. The identification wristband 3 has a built-in RFID tag with a unique ID. Both the directional reader 21 and the status indicator light 22 are connected to the control module 4, and both are connected to the WMS system 6 through the control module 4. When the identification wristband 3 passes through the identification plane 211, the directional reader 21 reads the ID information of the RFID tag.
[0020] By placing the directional reader 21 on the front side of the storage unit 111 of the shelf 1 to form an identification plane 211, when the operator wearing the identification wristband 3 reaches into the storage unit 111 to retrieve an item, the directional reader 21 corresponding to the storage unit 111 can verify the ID information of the identification wristband 3, thereby recording each item retrieval action of the operator. This enables identification and management of the operator, retrieval time, and retrieved item. After recording, the status indicator light 22 can be automatically turned off, reducing redundant actions and improving work efficiency. Furthermore, it can promptly remind the operator in case of mis-picking, ensuring correct item retrieval. Compared with traditional picking systems that rely solely on visual judgment, this invention effectively avoids mis-picking by combining the indication of the status indicator light 22 with the reading and writing of the identification wristband 3 by the directional reader 21.
[0021] The directional reader 21 and status indicator 22 communicate with the WMS system 6 to exchange information and use the WMS system 6 to realize material management.
[0022] Preferably, the system also includes a lighting controller, to which multiple status indicator lights 22 are connected. The lighting controller is connected to the control module 4. By setting the lighting controller, the optimal path plan automatically generated based on the picking task data obtained in real time by the WMS system 6 can be used to control the lighting sequence of the status indicator lights 22 corresponding to multiple target storage units 111, thereby guiding operators to work in the shortest route sequence and further improving work efficiency.
[0023] Preferably, the status indicator 22 has two indication states: green and red. Using the status indicator 22 with two indication states, before picking, the indicator light corresponding to the next target storage unit 111 is kept constantly green by the lighting controller to guide the operator to retrieve the item from the corresponding storage unit 111. When the operator, wearing the identification wristband 3, retrieves the item from the storage unit 111, the directional reader 21 verifies the ID of the identification wristband 3. If the action is correct, the status indicator 22 flashes for a few seconds and then turns off, and the indicator light corresponding to the next target storage unit 111 is lit. If a picking error occurs, the status indicator 22 corresponding to the error location lights up red, and an error log is sent to the WMS via the control module 4 to remind the operator.
[0024] Preferably, the identification unit also includes a buzzer connected to the control module 4. By setting the buzzer, it is triggered to sound when a wrong item is picked up, thus reminding the operator of the incorrect action. The buzzer sounding and the red light on the status indicator 22 form a differentiated sound and light combination to achieve a strong reminder.
[0025] Preferably, referring to Figure 2, the shelf 1 includes multiple sets of shelves 11 and support frames 12. The multiple sets of shelves 11 are arranged vertically on the support frames 12, and the identification units are fixed horizontally on the front side of the shelves 11. By fixing the identification units horizontally on the front side of the shelves 11, the identification plane 211 formed by the reading range of the directional reader 21 in each identification unit can longitudinally cover the space between adjacent shelves 11, while the lateral range can be adjusted according to the actual situation to adjust the distance between two identification units. This ensures that when the operator wears the identification wristband 3 and reaches into the shelf 1 to retrieve items, the directional reader 21 corresponding to the storage unit 111 can verify the ID information of the identification wristband 3, ensuring the correct identification of the retrieval status.
[0026] Furthermore, the shelf 1 also includes multiple storage boxes 13, which are arranged on the shelf 11 to form multiple storage units 111. Each storage box 13 corresponds to a recognition unit. By setting up the storage boxes 13, the storage capacity of the storage units is increased.
[0027] Preferably, the identification module 2 further includes an information display surface 23, with a status indicator light 22 located on one side of the information display surface 23. The information display surface 23 is used to display the component information of the corresponding storage unit 111.
[0028] Preferably, it also includes a display device 5, which is connected to the control module 4 and is mounted on the shelf 1. By setting up the display device 5, the operator's current task information and whether the picking is correct can be displayed.
[0029] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
