For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0022] Reference Figure 1 This embodiment illustrates a ceramic capacitor weighing and dispensing device, including a machine base 1, a feeding mechanism 2, a vibratory feeder feeding mechanism 3, a conveyor line 4, a weighing mechanism 5, a PLC controller, an operation panel 6, a reminder device 7, an electronic scale 8, and a barcode scanner 9.

[0023] The machine platform 1 has three sections. The feeding mechanism 2, the vibratory feeder mechanism 3, and the conveyor line 4 are located on the highest section of platform 1. The weighing mechanism 5 and the control panel 6 are located on the other two sections of platform 1, which are at a lower height. The height difference between the different sections allows materials to be fed from the conveyor line 4 to the weighing mechanism 5 under gravity. A space is reserved on platform 1 for placing an electronic scale 8, which is placed on the lower section of platform 1. The electronic scale 8 is used to weigh the materials before dispensing.

[0024] Specifically, the aforementioned feeding mechanism 2 is used to store materials that need to be divided, and to supply the materials to the vibratory feeder feeding mechanism 3 at the appropriate time. The vibratory feeder feeding mechanism 3 realizes the automatic regular arrangement of materials through vibration and conveys the materials to the conveyor line 4. The conveyor line 4 is used to convey the materials to the weighing mechanism 5.

[0025] The weighing mechanism 5 is located below the outlet of the conveyor line 4. The weighing mechanism 5 includes a measuring cup 51 and a weighing sensor. The measuring cup is positioned above the weighing sensor, which detects the weight information of the measuring cup. Both the weighing sensor and the feeding mechanism are electrically connected to a PLC controller. The PLC controller has a preset material weight. When the measured value of the weighing sensor equals the set value, the PLC controller controls the feeding mechanism to pause feeding. The operation panel 6 is electrically connected to the PLC controller, allowing control commands or related parameters to be input to the PLC controller. In this embodiment, the weighing sensor is integrated into a small electronic scale 52, and the measuring cup 51 is placed on the sensing platform on the top surface of the small electronic scale 52.

[0026] The reminder device 7 is electrically connected to the PLC controller. When the measured value of the weighing sensor equals the set value, the PLC controller controls the reminder device to emit sound and / or light to notify the user. Additionally, when no material is detected, the reminder device 7 can also emit sound and / or light to notify the user.

[0027] The barcode scanner 9 is electrically connected to the PLC controller. By scanning the batch card or personnel QR code with the barcode scanner 9, the weight information required for the current material distribution can be obtained.

[0028] Reference Figure 2 The feeding mechanism 2 includes a vertical vibrator 21, a support, a hopper 22, and a feeding channel 23. The hopper 22 is fixed to the power output end of the vertical vibrator 21 and the top of the support. The bottom end of the hopper 22 is provided with a discharge port, and the feeding channel 23 is located below the discharge port. The material in the hopper 22 slides down the feeding channel 23 under the action of gravity. When the vertical vibrator 21 is working, it can drive the feeding channel 23 to vibrate, so that the material in the feeding channel 23 falls into the vibrating plate feeding mechanism 3.

[0029] The vibratory feeder feeding mechanism 3 includes a vibratory motor 31, a vibratory feeder 32, a material shortage sensor, and a transition feeding channel 33. The vibratory feeder 32 is used to load materials. The vibratory feeder 32 is fixedly installed on the power output end of the vibratory motor 31. When the vibratory motor 31 is working, it can make the vibratory feeder 32 vibrate at a directional frequency so that the materials are automatically arranged and enter the transition feeding channel 33, and finally conveyed to the conveyor line 4.

[0030] A material shortage sensor (not shown in the figure) is installed on the vibratory feeder 32 and is electrically connected to the PLC controller. When no material is detected, the PLC controller controls the feeding mechanism 2 to feed material. In practical applications, a photoelectric sensor can be used. The emitting end of the photoelectric sensor emits light towards the bottom of the vibratory feeder. Since the light transmission path is different when there is material and when there is no material, the PLC controller can determine whether there is material based on the time it takes for the receiving end to receive the returned light.

[0031] Furthermore, referring to Figure 3 The vibratory feeder 32 has a spirally ascending conveyor track 321 on its internal cavity wall. The width of the conveyor track 321 is designed to match the specifications of the material. In this embodiment, the width of the conveyor track 321 can simultaneously accommodate five types of materials: 0201, 0402, 0603, 0805, and 1206. Furthermore, the bottom surface of the conveyor track 321 slopes downwards, and the material, under the influence of gravity, also slopes and abuts against the wall of the conveyor track, preventing the material from accidentally falling to the bottom of the vibratory feeder. Furthermore, the outlet of the material channel 23 is provided with a downwardly inclined distribution trough 24 for guiding the material to the edge of the vibratory feeder 32. By setting the distribution trough 24, the material can fall directly to the two sides of the vibratory feeder 32, accelerating the material distribution speed.

[0032] Furthermore, referring to Figure 4 The conveyor line 4 includes a servo motor 41, a belt 42, a pulley 43, and limit bars 44. The belt 42 is wound around the pulley 43, which is connected to the servo motor 41. The servo motor 41 drives the pulley 43 to rotate, thereby driving the belt 42 to move. The belt 42 conveys the material forward through its static friction with the material. The limit bars 44 are located on both sides of the belt 42 to prevent the material from falling accidentally. Preferably, the speed of the belt 42 is positively correlated with the speed of the vibratory feeder 32, and the speed of the belt 42 is greater than the maximum circular speed of the vibratory feeder 32. In addition, through program control, a single operation is divided into three segments based on weight: the first segment (accounting for most of the total weight) is fed quickly, the middle segment (accounting for half of the remaining weight) is fed at a slower speed, and the last segment is fed slowly. When the weight of a single feeding exceeds the remaining weight, the operation stops to avoid the last feeding not meeting the demand.

[0033] Through the above design, the material dispensing and weighing equipment of this application realizes automatic material dispensing and weighing of ceramic capacitors, which improves the material dispensing efficiency and measurement accuracy of ceramic capacitors compared with the existing manual material dispensing method.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
