[0041] The present invention provides an electronic material loading and unloading method, which is operated on an electronic material replenishing device, and the electronic material replenishing device includes a replenishing electronic material rack, including:

[0042] Step S110: In response to the request to start the shelf mode, obtain the identification code on the electronic material 1, where the identification code includes the electronic material type code.

[0043] In an exemplary embodiment, the operator clicks a "put on shelf" button on the screen of the electronic material replenishing device to enter the shelf mode. In another exemplary embodiment, a button for controlling the start of the shelf mode is provided on the electronic material replenishing device, and the operator clicks the "put on shelf" button to enter the shelf mode. The way in which the electronic material replenishing device enters the shelf mode can be adjusted according to specific needs.

[0044] In an exemplary embodiment, in response to a request to start the shelf mode, obtaining an identification code on the electronic material 1, the identification code including the electronic material type code, includes steps S210 and S220:

[0045] Step S210: The identification code includes the work order number; based on the identification code, the work order number is obtained.

[0046] Step S220: If the work order number is consistent with the reference work order number, the placement location information is generated; if the work order number is inconsistent with the reference work order number, a prompt is given through a prompt device.

[0047] In an exemplary embodiment, an operator places the electronic material 1 from a material frame onto a supplementary electronic material rack, and the materials in the material frame are picked according to the part type and quantity required for the same work order.

[0048] In an exemplary embodiment, the reference work order number can be input by an external input device. In another exemplary embodiment, the identification code on the electronic material 1 is obtained by the barcode scanner 6. The reference work order is the work order number of the identification code of the first electronic material 1 after switching to the loading mode. The method for determining the reference work order number can be adjusted according to actual production and use needs.

[0049] In an exemplary embodiment, the prompt device is a display screen, which pops up a dialog box on the display screen to prompt that the work order number is inconsistent with the reference work order number. In other embodiments, the prompt device is an indicator light 3, which prompts by turning on or off the light, or by switching the color of the light. The type of prompt device can be adjusted according to actual usage needs.

[0050] Step S120: Based on the identification code, generate placement position information corresponding to the corresponding position of the supplementary electronic material rack, and generate a mapping relationship between the identification code and the placement position information, wherein the identification code is a unique identifier for each electronic material 1.

[0051] In an exemplary embodiment, the identification code of each electronic material 1 on the supplementary electronic material rack has corresponding placement position information, and the placement position information corresponds to an electronic material placement position 2 on the supplementary electronic material rack.

[0052] In an exemplary embodiment, based on the identification code, generating placement position information corresponding to the corresponding position of the supplementary electronic material rack, and generating a mapping relationship between the identification code and the placement position information, including step S310:

[0053] Step S310: Light up the location of the supplementary electronic material rack corresponding to the placement position information so as to place the electronic material 1 into the corresponding location of the supplementary electronic material rack.

[0054] In an exemplary embodiment, the supplementary electronic material rack has at least two layers of electronic material placement layers, each electronic material placement layer is provided with a plurality of electronic material placement positions 2, and each electronic material placement position 2 is provided with a corresponding position indicator light 3 of the electronic material placement position 2, and the position indicator light 3 is lit, and the color is purple. After the operator or the intelligent robot puts the electronic material 1 into the lighted electronic material placement position 2, the position indicator light 3 switches to green. Through the change of the color of the position indicator light 3, the operator can be conveniently prompted and instructed to perform the loading operation, which is simple and efficient.

[0055] Step S130: In response to completing the shelf request, obtaining the delivery address and delivering to the production line corresponding to the delivery address.

In another exemplary embodiment, the electronic material replenishing device is provided with a button for controlling the closing of the on-shelf mode, and the operator clicks the "Finish" button to exit the on-shelf mode. The way in which the electronic material replenishing device exits the on-shelf mode can be adjusted according to specific needs.

[0057] In an exemplary embodiment, an operator next to the production line selects the required work order number through a PDA (Personal Digital Assistant) and scans the line address code at the same time. The line address code includes the delivery address, and calls the electronic material replenishing device corresponding to the work order number. The electronic material replenishing device is sent to the production line corresponding to the delivery address by an automatic guided vehicle 5. Universal wheels 4 are also provided at the bottom of the electronic material replenishment rack to facilitate movement.

[0058] Step S140: in response to the request to start the off-shelf mode, the empty tray identification code on the empty tray electronic material 1 is obtained, and the empty tray electronic material type code is extracted.

[0059] In an exemplary embodiment, the operator clicks the "off-shelf" button on the screen of the electronic material replenishing device to enter the off-shelf mode. In another exemplary embodiment, the electronic material replenishing device is provided with a button for controlling the on-shelf mode, and the operator clicks the "off-shelf" button to enter the on-shelf mode. The way in which the electronic material replenishing device enters the off-shelf mode can be adjusted according to specific needs.

[0060] Step S150: Based on the mapping relationship between the empty tray electronic material type code, the electronic material type code and the identification code and the placement position information, the supplementary electronic material position is obtained to replace the empty tray electronic material 1 by the electronic material 1 at the supplementary electronic material position, thereby supplementing the empty tray electronic material 1.

[0061] By obtaining the empty tray identification code on the empty tray electronic material 1, the empty tray electronic material type code corresponding to the current empty tray can be known, so that the required electronic material type code can be searched on the corresponding supplementary electronic material shelf through the empty tray electronic material type code, thereby finding the identification code of the electronic material placed on the supplementary electronic material shelf. It should be noted here that if there are multiple electronic material type codes that are the same as the empty tray electronic material type code on the supplementary electronic material shelf, the time point of placing them on the supplementary electronic material shelf is used as the order of extracting electronic materials with the same electronic material type code. In an exemplary embodiment, if there are multiple electronic materials 1 with the same electronic material type code as the empty tray on the supplementary electronic material shelf, the electronic material 1 that is first placed on the supplementary electronic material shelf is extracted. In another exemplary embodiment, if there are multiple electronic materials 1 with the same electronic material type code as the empty tray on the supplementary electronic material shelf, the electronic material 1 that is last placed on the supplementary electronic material shelf is extracted. The above extraction rules can be adjusted according to actual needs.

[0062] In an exemplary embodiment, based on the mapping relationship between the empty tray electronic material type code, the electronic material type code and the identification code and the placement position information, the supplementary electronic material position is obtained, including step S410 and step S420:

[0063] Step S410: extract the electronic material type code in the identification code, search for the empty disk electronic material type code in the electronic material type code, obtain the target electronic material type code, and obtain the supplementary electronic material position based on the identification code of the target electronic material type code and the mapping relationship between the identification code and the placement position information.

[0064] Step S420: Light up the position of the electronic material replenishment shelf corresponding to the electronic material replenishment position to provide a prompt.

[0065] The position of the electronic material 1 on the electronic material replenishment rack is indicated by lighting a light, which is intuitive and convenient for the operator to operate.

[0066] In an exemplary embodiment, after lighting a light at a location of the replenished electronic material shelf corresponding to the replenished electronic material for prompting, the method further includes step S510:

[0067] Step S510: Obtain the identification code of the electronic material 1 placed at the replenishment electronic material position, extract the electronic material type code, and turn off the light based on the electronic material type code and the empty tray electronic material type code to provide a prompt.

[0068] After the operator extracts the electronic material 1 at the lighted position on the supplementary electronic material rack, the operator obtains the identification code of the electronic material 1 by scanning the code. Since the identification code includes the electronic material type code, the electronic material type code of the electronic material 1 can be obtained. The electronic material type code of the electronic material 1 is compared with the electronic material type code of the empty tray to determine that the electronic material type code is the same as the electronic material type code of the empty tray, so as to verify the correctness of the extracted electronic material 1 and avoid the situation where the electronic material type code is different from the electronic material type code of the empty tray, and unnecessary electronic material 1 is extracted from the supplementary electronic material rack.

[0069] The present invention provides an electronic material replenishing device, using the electronic material loading and unloading method as described above, comprising:

[0073] In an exemplary embodiment, the electronic material replenishment rack is provided with universal wheels 4 for sliding and an automatic guided vehicle 5, and the automatic guided vehicle 5 is used to move the electronic material replenishment device back and forth between the production line and the warehouse.

[0074] By transporting the replenished electronic material racks through the automatic guided vehicle 5, the manual labor of the operators can be reduced and the efficiency of loading and unloading materials can be improved.

[0075] In an exemplary embodiment, the electronic material rack body has at least two layers of electronic material placement layers, each electronic material placement layer is provided with a plurality of electronic material placement positions 2, the electronic material placement positions 2 are arranged in sequence along a first direction, adjacent electronic material placement positions 2 are staggered in a second direction, and the first direction is perpendicular to the second direction.

[0076] By arranging adjacent electronic material placement positions 2 in a staggered manner in the second direction, it is convenient for operators or intelligent robots to take and place electronic materials 1.

[0077] In an exemplary embodiment, the indicator is a position indicator light 3, which is arranged corresponding to the electronic material placement position 2. In another exemplary embodiment, the indicator may be an indicator rod that can be raised and lowered, and when the indicator rod is raised, the electronic material placement position 2 is exposed, which is convenient for operators or intelligent robots to place electronic materials 1, and when the indicator rod is lowered, the electronic material placement position 2 is covered to prompt that the electronic material 1 should not be placed there.
