The terms used in this specification are only for the purpose of describing specific embodiments and are not used to limit the present invention. The term "and / or" used in this specification includes any and all combinations of one or more related listed items.

[0020] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0021] Figure 1 A schematic diagram of an automatic weighing device provided in an embodiment of the present application, such as Figure 1 As shown, the automatic weighing device 10 includes: a hopper 11, a slide unit 12 and a material receiving assembly 13 which are connected in sequence.

[0022] The hopper 11 includes: a feed port 111, a discharge port 112, a baffle 113 and a bottom 114 having a slope shape. The baffle 113 is arranged around the bottom 114, the feed port 111 is formed above the bottom 114, and the discharge port 112 is formed in the downhill direction of the bottom 114.

[0023] In some embodiments, a transmission plate with baffles on both sides may be provided at the discharge port 112 to extend the discharge port 112 .

[0024] As an example but not limitation, the slope shape of the bottom 114 can be formed by cutting a cylindrical object, a rectangular object, or a cube object.

[0025] By disposing the baffle 113 around the bottom 114 , it can be ensured that only the discharge port 112 can discharge the material.

[0026] For example, assuming that the material is a chip capacitor, the chip capacitor falls from the feed port 111 into the bottom 114 . Under the slope of the bottom 114 , the chip capacitor slides down the slope of the bottom 114 to the discharge port 112 due to gravity.

[0027] The slide unit 12 includes a slide assembly 121 and a vibrator 122 , and the slide assembly 121 is placed on the vibrator 122 .

[0028] It should be noted that the vibrator 122 can vibrate the slide assembly 121 so that the material falling into the slide assembly 121 is vibrated and moves, thereby causing the material to fall into the material receiving assembly 13 .

[0029] It should be noted that the slideway assembly 121 is made of a hard material, such as aluminum oxide, so as to reduce wear.

[0030] The material receiving assembly 13 comprises: a material receiving cup 131 and a weighing sensor 132 , and the material receiving cup 131 is placed on the weighing sensor 132 .

[0031] It should be noted that the weighing sensor 132 can detect the weight of the material receiving cup 131 , including the weight of the material receiving cup 131 itself and the weight of the material in the material receiving cup 131 .

[0032] For example, the capacity of the receiving cup 131 may be 1000 milliliters (mL).

[0033] The weighing sensor 132 is electrically connected to the vibrator 122 , so that when the vibrator 122 learns from the weighing sensor 132 that the material in the receiving cup 131 has reached the target weight, the vibration is stopped.

[0034] As an example but not limitation, a preset target weight can be input into the weighing sensor 132. When the weighing sensor 132 detects that the material in the receiving cup 131 has reached the target weight, a control instruction is generated, and the control instruction is transmitted to the vibrator 122, so that the vibrator 122 stops vibrating according to the control instruction, so that the material falling into the slide assembly 121 stops moving.

[0035] At least one advantageous aspect of the automatic weighing equipment provided in the embodiment of the present application is that materials are loaded and unloaded through a hopper, the materials are transported to a receiving cup through a slide unit, and automatic weighing is achieved through a weighing sensor, thereby avoiding the problem of large errors caused by manual measurement and improving the accuracy of material weighing.

[0036] It should be noted that the embodiments of the present application are for the sake of simplicity and illustrative purposes only, showing the application scenario of the automatic weighing device for weighing chip capacitors. However, those skilled in the art will appreciate that, based on similar principles, the automatic weighing device provided in the embodiments of the present application can also be applied to weighing scenarios of other materials. The utility model ideas disclosed in the embodiments of the present application are not limited to Figure 1 The method is applied to the automatic weighing device shown, and can also be used in other similar weighing devices.

[0037] In some embodiments, Figure 1 As shown, the automatic weighing device 10 further includes a control unit 14 . The control unit 14 includes a display screen 141 , a three-color light 142 , and a scanning gun 143 .

[0038] The display screen 141 is electrically connected to the weighing sensor 132 , so that the weighing sensor 132 obtains the target weight corresponding to the material to be weighed from the display screen 141 .

[0039] It should be noted that the display screen 141 has a data input function and can input the target weight corresponding to the material to be weighed.

[0040] In some embodiments, the display screen 141 is a touch screen, and data input can be achieved by touching the display screen 141 .

[0041] In some embodiments, the display screen 141 is provided with a login level interface, which enables visualization of login data.

[0042] The three-color light 142 includes a yellow light, a red light, and a green light. When the yellow light is on, it indicates that the automatic weighing device 10 stops running; or when the red light is on, it indicates that the automatic weighing device 10 is abnormal; or when the green light is on, it indicates that the automatic weighing device 10 is running normally.

[0043] As an example but not limitation, the positions of the yellow light, the red light and the green light can be arranged horizontally or vertically, and the sorting order of the three-color lights 142 is not limited.

[0044] The scanner 143 is used to collect relevant data corresponding to the material to be weighed. It should be noted that the scanner 143 is electrically connected to the display screen 141 so that the scanner 143 transmits the collected data to the display screen 141.

[0045] It should be noted that the relevant data corresponding to the material to be weighed includes but is not limited to the target weight corresponding to the material.

[0046] As an example but not limitation, the scanner 143 can scan a QR code or a barcode. For example, a bill of materials corresponding to a material is attached with a QR code, and the QR code records the required weight of the material, so that the QR code of the bill of materials is scanned by the scanner 143 to obtain the target weight corresponding to the material to be weighed, and then the target weight information is transmitted to the display screen 141.

[0047] In the existing chamfering process, the weight of the chip capacitors is manually entered, which is prone to manual entry errors or artificial falsification of data, resulting in the quantity of subsequent processes not matching, which in turn requires subsequent processes to spend more manpower and material resources to trace the whereabouts of the lost chip capacitors, resulting in an extension of the chamfering process cycle of the chip capacitors.

[0048] Therefore, the embodiment of the present application adds a weighing unit to the automatic weighing device 10 to solve at least part of the defects existing in the prior art.

[0049] In some embodiments, Figure 1 As shown, the automatic weighing device 10 further includes a weighing unit 15 .

[0052] In some embodiments, the weighing unit 15 is an electronic scale, the weighing range of the electronic scale is 0.0 to 10.0 kilograms, and the accuracy of the electronic scale is 0.1 grams.

[0055] In some embodiments, Figure 1 As shown, the automatic weighing device 10 further includes a gas vibrator 16 .

[0056] The hopper 11 is placed on the gas vibrator 16 so that all materials in the hopper 11 are shaken off to the slide unit 12 by the vibration of the gas vibrator 16 .

[0057] In some embodiments, the interior of the hopper 11 is treated with anti-static spraying to prevent the material from being affected by static electricity.

[0058] In some embodiments, the receiving cup 131 is provided with a cup spout, so that when pouring out the material in the receiving cup 131, all the material in the receiving cup 131 is poured out from the cup spout. This prevents the material in the receiving cup 131 from falling to the ground due to the interaction between the materials, thereby damaging the material.

[0059] In some embodiments, Figure 1 As shown, the slide assembly 121 includes: a starting end 1211 located below the discharge port 112 of the hopper 11 , an end 1212 located above the receiving cup 131 , a transmission plate 1213 between the starting end 1211 and the end 1212 , and baffles 1214 on both sides of the transmission plate 1213 .

[0060] The starting end 1211 is provided with a baffle plate so that the materials falling from the discharge port 112 all fall onto the transmission plate 1213 .

[0061] The end 1212 is set as an inclined surface, and the width of the end 1212 is smaller than the width of the receiving cup 131, so that the material falling on the transmission plate 1213 falls into the receiving cup 131 through the end 1212 through the vibration of the slide assembly 121 by the vibrator 122.

[0062] In some embodiments, Figure 1As shown, the transmission plate 1213 includes: a first transmission plate 12131 and a second transmission plate 12132 .

[0063] The first transmission plate 12131 is in a rectangular shape and is disposed between the starting end 1211 and the ending end 1212 . Baffles are disposed on both sides of the first transmission plate 12131 .

[0064] The end 1212 includes a second transmission plate 12132 and baffles on both sides of the second transmission plate 12132 .

[0065] Among them, the shape of the second transmission plate 12132 is an isosceles trapezoid, the lower bottom of the second transmission plate 12132 is connected to the first transmission plate 12131, the upper bottom of the second transmission plate 12132 is located above the material receiving cup 131, and the width of the upper bottom of the second transmission plate 12132 is smaller than the width of the material receiving cup 131, and the lower bottom is higher than the upper bottom to form an inclined surface, so that through the vibration of the slide assembly 121 by the vibrator 122, the material falling on the first transmission plate 12131 will pass through the lower bottom and the upper bottom in turn and fall into the material receiving cup 131.

[0066] In some embodiments, the slide unit 12 further includes a protective cover, wherein the protective cover is placed above the slide assembly 121 to prevent foreign objects from falling into the slide assembly 121 .
