Description

Technical Field

[0001] The invention relates to the technical field of process weighing, in particular to an electronic scale. Background Art

[0002] In the field of industrial manufacturing, electronic scales play an important role in production and processing. They are mainly used to accurately weigh raw materials and finished products to ensure product quality and production efficiency. At present, there are many electronic scales on the market that can automatically alarm. Their commonality is that they only use fixed three-color lights to alarm the upper and lower limits of quality. The existing solution uses a three-color alarm light composed of red, yellow and green connected to the back of the electronic scale. According to the relationship between the weighing mass and the set range (above, below and within the range), the corresponding lights (red, yellow and green) are displayed respectively.

[0003] In some industrial production processes, different raw materials need to be added to the production equipment one by one in a certain order according to the process requirements, and each raw material needs to be weighed by an electronic scale and can only be added to the production equipment after reaching the required quality. In order to prevent confusion in the addition of raw materials, it is usually added directly to the production equipment after weighing one raw material. The weighing order of the raw materials must be consistent with the order in which the raw materials are added to the production equipment.

[0004] When personnel do not follow the operating instructions, it is easy to cause the weighing sequence to be disordered, resulting in the disorder of the sequence of raw materials being put into the equipment, which further leads to product quality problems. However, the existing electronic scale alarm system is too simple, only alarming the upper and lower limits of the raw material weighing quality, and cannot meet the control needs of weighing raw materials in the production process.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0043] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides an electronic scale, which includes an electronic scale body 1, a source material determination module, a controller 8, and a plurality of source material alarm lights 2. The source material determination module, the controller 8, and the plurality of source material alarm lights 2 are all arranged on the electronic scale body 1. The source material determination module and the plurality of source material alarm lights 2 are all electrically connected to the controller 8. The source material determination module is used to feed back the type of the weighed source material to the controller 8. Each source material alarm light 2 corresponds to a source material. The controller 8 is preset with the weighing order of each source material, and the plurality of source material alarm lights 2 can display different colors according to the weighing order of the source material.

[0044] When weighing multiple source materials, the source material determination module will feed back the type of weighed source material to the controller 8. The controller 8 can determine whether the weighing of the source material is in a preset order based on the type of source material fed back. When the weighing is performed in a preset weighing order, the controller 8 will control the source material alarm light 2 to display a corresponding color to remind the operator. When the weighing is not performed in the preset weighing order, the controller 8 will control the source material alarm light 2 to display a different color. The operator can determine whether the weighing is performed in a preset order based on the different displayed colors, thereby achieving the purpose of reminding the operator and re-weighing afterwards. By adopting the source material determination module and the source material alarm light, the problem of disorder in the order of source material input equipment caused by disorder in the source material weighing order can be avoided, thereby ensuring product quality and meeting the control requirements for weighing source materials in the production process.

[0045] In some embodiments of the present invention, the electronic scale further includes a weighing module, which is used to weigh the mass of each source material. The weighing module is electrically connected to the controller 8. The controller 8 is preset with a mass range of each source material, and the multiple source material alarm lights 2 can also display different colors according to the weighed mass of the source material.

[0046] When the source material is weighed, the weighing mass of the source material can be obtained through the weighing module. The weighing module feeds back the weighing mass of the source material to the controller 8. The controller 8 retrieves the corresponding source material mass range according to the source material type fed back by the source material determination module, and judges whether the source material is within the preset mass range according to the fed-back source material weighing mass. When the weighing mass of the source material reaches the preset mass range, the source material alarm light 2 will display a corresponding color to remind the operator. When the weighing mass of the source material does not reach the preset mass range, the source material alarm light 2 will display a different color. The operator can judge whether the source material mass is within the preset mass range based on the different displayed colors, thereby achieving the purpose of reminding the operator, thereby ensuring the accuracy of the source material weighing and improving the quality of the product.

[0047] In some embodiments of the present invention, each source material alarm light 2 can sound an alarm. While the source material alarm light 2 alarms by displaying different colors, it also adds a sound alarm, so that the operator can more conveniently obtain the alarm signal and the alarm effect is more obvious. Optionally, the source material alarm light 2 has a built-in buzzer.

[0048] Optionally, a plurality of source material warning lights 2 are arranged vertically, and two adjacent source material warning lights 2 are fixedly connected. A connecting rod is fixedly connected to the source material warning light 2, and the source material warning light 2 is fixedly connected to the side wall of the electronic scale body 1 through the connecting rod. Of course, a plurality of source material warning lights 2 can also be arranged horizontally at intervals or individually arranged.

[0049] In some embodiments of the present invention, the weighing module includes a weighing panel 11 and a weighing sensor 7. The weighing panel 11 is horizontally arranged on the upper surface of the electronic scale body 1, and the weighing panel 11 is fixedly placed on the weighing sensor 7, and the weighing sensor 7 is electrically connected to the controller 8.

[0050] When the source material needs to be weighed, the source material is placed on the weighing panel 11. After the weighing sensor 7 senses the source material, the source material is weighed and the weighed mass is transmitted to the controller 8. The entire weighing module has a relatively simple structure and is easy to operate.

[0051] In some embodiments of the present invention, the source material determination module includes a plurality of selection buttons 3 , the selection buttons 3 are electrically connected to the controller 8 , and each selection button 3 corresponds to a source material.

[0052] When the source material is weighed, the source material to be weighed is first selected by selecting the button 3, and the controller 8 can obtain the type of the source material currently being weighed according to the signal fed back by the selection button 3, and call up the mass range corresponding to the source material. By using the selection button 3, when the type of the weighed source material is fed back to the controller 8, the structure is simpler and the operation is more convenient.

[0053] In some embodiments of the present invention, a plurality of source material boxes 4 are further provided on the side wall of the electronic scale body 1, and each source material box 4 corresponds to a source material. The source material box 4 is used to place the corresponding source material. When the source material needs to be taken out for weighing, the source material can be avoided from being mixed up, and there is no need to find an additional source material storage frame, which is more convenient.

[0054] Furthermore, the source material box 4 is detachably connected to the electronic scale body 1, so that it is convenient to add source material into the source material box 4, and the source material box 4 can be disassembled for cleaning.

[0055] Optionally, a hook is provided on the side wall of each source box 4, and a hanging ring is provided on the side wall of the corresponding electronic scale body 1. The source box 4 is hung on the hanging ring through the hook to achieve the connection between the source box 4 and the electronic scale body 1. The structure is simple and easy to disassemble.

[0056] Optionally, a plurality of source boxes 4 can be fixedly connected side by side to form a whole. In this case, only a hook and a hanging ring need to be provided to facilitate the overall disassembly of the source box 4.

[0057] Furthermore, labels of corresponding source materials are attached to the source material boxes 4, so that operators can more clearly determine the type of source materials in each source material box 4 to prevent source material confusion.

[0058] In some embodiments of the present invention, magnetic tweezers 5 are further provided on the side wall of the electronic scale body 1. The magnetic tweezers 5 are fixed to the electronic scale body 1 by magnetic adsorption, and the magnetic tweezers 5 are used to clamp the source material. By providing the magnetic tweezers 5, there is no need to find additional tweezers to clamp the source material, which is more convenient. In addition, the tweezers are fixed to the electronic scale housing by magnetic adsorption, which makes it more convenient to take and put the tweezers.

[0059] In some alternative embodiments of the present invention, a placement groove may be provided on the side wall of the electronic scale body 1, and the tweezers may be placed in the placement groove, which also facilitates the use of the tweezers.

[0060] In some embodiments of the present invention, the electronic scale further includes a display screen 6, which is disposed on the electronic scale body 1 and is electrically connected to the controller 8. The display screen 6 is used to display the weighing mass of each source material. When the source material is weighed, the mass of the source material will be displayed on the display screen 6, so that the operator can intuitively obtain the weighing mass of each source material.

[0061] Furthermore, the display screen 6 is an LED screen. Of course, the display screen 6 can also be a touch screen. The use of LED screens and touch screens has a relatively simple structure, relatively mature technology, and lower cost. When the display screen 6 is a touch screen, the selection button 3 can be integrated into the touch screen.

[0062] In the wafer gold evaporation process, the corresponding gold evaporation equipment uses fixed source materials including Al, Ti, Ni and Ag. Before each round of the process, it is necessary to manually weigh and record the quality of the source materials. When the quality of the source materials is not within the quality range required by the process, the source materials need to be added or removed. Then, according to the process requirements, the weighed source materials are added to the crucible of the gold evaporation machine in the order of Al-Ti-Ni-Ag. Therefore, the above electronic scale can be applied to the wafer gold evaporation process.

[0063] Specifically, the source material alarm light 2, the selection button 3 and the source material box 4 are all set to four and correspond to the source materials Al, Ti, Ni and Ag respectively. The source material alarm light 2 can display orange, green, red and purple colors respectively. According to the process requirements, the preset source material weighing sequence is Al-Ti-Ni-Ag. And according to the process requirements, the mass range of each of the four source materials is determined, and the mass range is set in the controller 8.

[0064] like Figure 3 and Figure 4 As shown, in the power-off state, the four source material warning lights 2 are all in a colorless state. When the machine is turned on, in the initial state, the four source material warning lights 2 are all in an orange state.

[0065] like Figure 5As shown, when weighing according to the preset weighing sequence, the source material Al is weighed first, then the source material Ti, then the source material Ni, and finally the source material Ag. Before weighing the source material Al, press the selection button 3 corresponding to the source material Al. When the weighed mass is within the preset mass range, the source material alarm light 2 corresponding to the source material Al turns from orange to green. When the weighed mass is outside the set mass range, the source material alarm light 2 corresponding to the source material Al turns from orange to red and sounds an alarm to remind the operator that the source material weighing mass is not within the mass range and to make corresponding adjustments. After the operator adjusts it to within the mass range, the source material alarm light 2 turns from red to green and stops the alarm. At this time, the operator can add the weighed source material Al to the crucible of the gold steaming machine. Similarly, the source materials Ti, Ni and Ag can be weighed successively, and when the corresponding source material alarm light 2 shows green, the weighed source materials Ti, Ni and Ag are added to the crucible of the gold steaming machine in sequence.

[0066] When weighing is not performed in accordance with the preset weighing sequence, the source material alarm light 2 corresponding to the skipped source material will be displayed in purple, and an audible alarm will be sounded. Figure 6 As shown, when the source material Al is skipped and the source material Ti is weighed directly, the source material alarm light 2 corresponding to the source material Al displays purple and a sound alarm is sounded. The source material alarm light 2 corresponding to the source material Ti displays green or red according to the weighed mass of the source material Ti. At this time, the operator observes that the source material alarm light 2 corresponding to the source material Al displays purple, and knows that the source material Al has not been weighed, so it is re-weighed, which serves to remind the operator to avoid confusion in the order of adding the source materials to the crucible of the gold steaming machine. Figure 7 As shown, when the source materials Al and Ti are skipped and the source material Ni is weighed directly, the source material alarm lights 2 corresponding to the source materials Al and Ti display purple, and a sound alarm is issued, and it can also be known that the source materials Al and Ti have not been weighed. At this time, the source material alarm light 2 corresponding to the source material Ni displays green or red according to the weighed mass of the source material Ni. Similarly, skip the source materials Al, Ti and Ni, and weigh the source material Ag first. The source material alarm lights 2 corresponding to the source materials Al, Ti and Ni display purple, and a sound alarm is issued. At this time, the source material alarm light 2 corresponding to the source material Ag displays green or red according to the weighed mass of the source material Ag. As shown Figure 8As shown, the source material Al is weighed first, the source material Ti is skipped and the source material Ni is weighed directly. The source material alarm light 2 corresponding to the source material Ti displays purple, and a sound alarm is issued. At this time, the source material alarm lights 2 corresponding to the source materials Al and Ni display green or red according to the weighed masses of the source materials Al and Ni. Similarly, the source materials Al and Ti are weighed first, the source material Ni is skipped and the source material Ag is weighed directly. The source material alarm light 2 corresponding to the source material Ni displays purple, and a sound alarm is issued. At this time, the source material alarm lights 2 corresponding to the source materials Al, Ti and Ag display green or red according to the weighed masses of the source materials Al, Ni and Ag.

[0067] To sum up, in the wafer gold vaporization process, according to the different colors displayed by the above-mentioned source material alarm lights 2, the operator can be reminded when the weighing is not carried out according to the preset order and when the weighing quality is not within the preset quality range, thereby meeting the control needs of weighing source materials in the wafer gold vaporization process.
