Description

Technical Field

[0001] This utility model relates to the technical field of motorcycle parts production equipment, specifically to a precision quantitative filler and quantitative sand feeding device applied to the motorcycle ignition assembly process. Background Technology

[0002] In the production process of motorcycle igniters, it is necessary to fill the igniter container with fillers such as quartz sand to meet its performance requirements. Traditional filling methods mostly rely on manual operation, with workers manually filling each container one by one. This is not only labor-intensive and inefficient, but also makes it difficult to ensure that the amount of filler is accurate and consistent each time, easily resulting in too much or too little filler, affecting the quality stability of the igniter and consequently the overall performance of the motorcycle. Bulk feeding is prone to dust pollution; multiple workstations require repeated positioning. Existing technology uses a vibratory feeding method, but it suffers from problems such as uneven particle size sorting and poor positioning accuracy (±2mm). With the rapid development of the motorcycle industry, the demand for igniters is increasing day by day, urgently requiring a high-efficiency and precise quantitative sand feeding device to meet production needs. Utility Model Content

[0003] The purpose of this utility model is to address the aforementioned problems and deficiencies by providing a quantitative sand dispensing device for motorcycle ignition fillers, thereby solving the problems of low efficiency and inaccurate quantitative dispensing in the existing technology, achieving automated and accurate quantitative feeding, and improving production efficiency and product quality.

[0004] The technical solution adopted in this utility model is as follows:

[0005] A device for metering and distributing sand for motorcycle ignition filler includes:

[0006] A frame and a worktable; an X-axis moving mechanism mounted on the frame, the X-axis moving mechanism including an X-axis track, an X-axis moving gantry, an X-axis drive motor and a transmission mechanism, the X-axis moving gantry being able to reciprocate linearly along the X-axis direction;

[0007] The Y-axis moving mechanism is installed on the crossbeam of the X-axis moving gantry. The Y-axis moving mechanism includes a Y-axis track, a Y-axis moving slider, a Y-axis motor and a transmission mechanism.

[0008] A Z-axis lifting mechanism connected to the Y-axis moving slider, the Z-axis lifting mechanism includes a motor and a transmission mechanism, and can lift vertically;

[0009] At least one set of matrix positioning fixtures is placed on the workbench. The matrix positioning fixtures include a tray and several cell sub-containers arranged in a matrix in the tray for placing quartz sand.

[0010] The Z-axis lifting mechanism includes a lifting motor, a Z-axis lifting rail, and a Z-axis lifting slide plate mounted on the Z-axis lifting rail. The Z-axis lifting rail is mounted on the slide plate. The lifting motor drives the Z-axis lifting slide plate to move up and down on the Z-axis lifting rail via a transmission mechanism, thereby achieving vertical lifting motion and driving the unloading mechanism to complete the filling operation.

[0011] The feeding mechanism is mounted on the Z-axis lifting mechanism. The feeding mechanism includes a storage hopper, a solenoid valve, and a feeding hopper. The opening degree and opening time of the solenoid valve are programmable and controllable. The storage hopper is fixedly mounted on the slider and is used to store quartz sand. The solenoid valve is installed at the bottom outlet of the storage hopper and is electrically connected to the controller system. Under the control of the controller, the solenoid valve opens and closes precisely to control the feeding of quartz sand. The feeding hopper is mounted on the Z-axis lifting slide plate, located below the storage hopper.

[0012] Priority is given to the controller system that controls the operation of the motor and the opening and closing of the feeding control valve. The controller system includes a PLC, displacement sensors, and solenoid valve controllers, and triggers the feeding sequence through a positioning signal. As the control core of the entire device, the controller system is electrically connected to the motors driving the X, Y, and Z axes, as well as the solenoid valves. Each time the Z-axis lifting rail descends to its designated position, it triggers the displacement sensor mounted on it. The displacement sensor sends a signal to the controller system, which, upon receiving the signal, controls the solenoid valve to open, starting the feeding into the corresponding cell sub-container below. When the preset feeding time or weight, or other quantitative conditions, is reached, the controller system controls the solenoid valve to close, stopping the feeding, and sends a signal to the motor to drive the shifting mechanism, moving the feeding mechanism to the next filling position. This cycle repeats, achieving automated quantitative sand feeding.

[0013] Preferably, the transmission mechanism is one or more combinations of a lead screw and nut pair, a gear and rack pair, or a synchronous belt transmission mechanism.

[0014] Preferably, the controller system is connected to a weight sensor or timer for monitoring the amount of material fed.

[0015] Preferably, the workbench is equipped with pads, and at least two sets of frames for placing matrix positioning fixtures are installed on the pads.

[0016] Preferably, the feeding mechanism includes a storage hopper, a solenoid valve, and a feeding hopper, wherein the opening degree and opening time of the solenoid valve are programmable and controllable.

[0018] Preferably, the top of the hopper is equipped with a dust cover to prevent dust and impurities from falling into the hopper and affecting the quality of the quartz sand. An electrostatic eliminator is installed on the frame.

[0021] 2. Precise Quantification: Under the precise control of the controller system, the solenoid valve opens and closes precisely according to the set feeding parameters, and the timing of feeding is controlled by the Z-axis positioning signal, ensuring that the amount of quartz sand injected into the cell sub-container is accurate and consistent each time, which effectively improves the stability of product quality and reduces the scrap rate;

[0022] 3. High positioning accuracy: The three-axis linkage positioning system adopts a ball screw and linear guide structure, and the X / Y axis repeatability positioning accuracy reaches ±0.05mm;

[0023] 4. Intelligent feeding control: Integrating weighing feedback and time-pressure composite algorithm to achieve a quantitative accuracy of ±0.5%;

The Y-axis moving slider 31 can reciprocate linearly along the Y-axis direction. A Z-axis lifting mechanism connected to the Y-axis moving slider 31 includes a motor and a transmission mechanism and can lift vertically.

[0034] At least one set of matrix positioning fixtures is placed on workbench 1. One, two, three, or four sets of matrix positioning fixtures may be placed, but typically two sets are placed. Figure 3 As shown, in some embodiments, four sets of matrix positioning fixtures are placed. The matrix positioning fixture includes a tray 41 and a plurality of cell sub-containers 42 arranged in a matrix in the tray 41 for placing quartz sand. The number of cell sub-containers 42 is configured according to the specific situation.

[0035] The feeding mechanism, installed on the Z-axis lifting mechanism, includes a storage hopper 51, a solenoid valve 52, and a feeding hopper 53. The opening degree and opening time of the solenoid valve 52 are programmable and controllable.

[0036] The system includes a controller system for controlling the operation of the motor and the opening and closing of the solenoid valve 52. The controller system includes a PLC, a displacement sensor and a solenoid valve controller, which triggers the feeding sequence through the arrival signal.

[0037] In this embodiment, the Z-axis lifting mechanism includes a lifting motor 61, a Z-axis lifting rail, and a Z-axis lifting slide plate 62 mounted on the Z-axis lifting rail. The Z-axis lifting rail is mounted on the Y-axis moving slider 31. The lifting motor 61 drives the Z-axis lifting slide plate 62 to move up and down on the Z-axis lifting rail via a transmission mechanism, achieving vertical lifting motion and driving the feeding mechanism to complete the filling operation. The storage hopper 51 is fixedly mounted on the Y-axis moving slider and is used to store quartz sand. The solenoid valve 52 is installed at the bottom outlet of the storage hopper 51. The solenoid valve 52 is electrically connected to the controller system and opens and closes precisely under the control of the controller to control the feeding of quartz sand. The feeding hopper 53 is mounted on the Z-axis lifting slide plate 62 and is located below the storage hopper 51.

[0038] In this embodiment, the transmission mechanism is one or more combinations of a lead screw and nut pair, a gear and rack pair, or a synchronous belt transmission mechanism.

[0039] In this embodiment, a pad strip 11 is installed on the workbench 1, and at least two sets of frames 12 for placing matrix positioning fixtures are installed on the pad strip 11.

[0040] In some embodiments, the controller system is connected to a weight sensor or timer for monitoring the amount of material fed.

[0041] In some embodiments, the top of the storage hopper 51 is provided with a dust cover, and an electrostatic eliminator is provided on the frame.

[0042] In some embodiments, the matrix positioning fixture adopts a quick-change design and is equipped with a reference positioning hole and a vacuum adsorption device, with a reference positioning hole spacing error of ≤0.1mm.

[0043] The working principle of this utility model:

[0044] After the device is started, the controller system initializes various parameters, such as the starting positions of the X and Y axes, the lifting height of the Z axis, and quantitative parameters such as feeding time or weight. First, the Z-axis lifting track rises to its initial high position under the drive of the motor, away from the worktable. At this time, the X and Y axis moving tracks move the worktable to the position of the first cell sub-container 42 to be filled, located directly below the feeding hopper 53, according to the preset program. Then, the Z-axis lifting slide plate 62 descends. When it descends to the correct position and triggers the position sensor, the sensor sends a signal to the controller. The controller immediately controls the solenoid valve 52 to open, and the quartz sand in the storage hopper 51 begins to fall, passing through the feeding hopper 53 and being injected into the cell sub-container 42 below the feeding hopper 53. The controller system monitors the feeding situation through a built-in timer or a connected weight sensor. When the preset quantitative condition is reached, it controls the solenoid valve 52 to close, stopping the feeding. Subsequently, the Z-axis lifting rail rises a certain distance, and the X and Y-axis moving rails move again, moving the worktable to the next filling position. The above steps are repeated, and this cycle continues until the filling work of all igniter containers is completed.

[0045] Parameter adjustment of this utility model:

[0046] During production, if it is necessary to change to a different specification of igniter or adjust the amount of filling material, the operator can input new parameters through the human-machine interface of the controller system, such as the movement step distance of the X and Y axes, the lifting height of the Z axis, the feeding time or weight threshold, etc. The controller system will automatically adjust the operation of the device according to the new parameters, which can easily and quickly adapt to changes in production.

[0047] In some embodiments, the X-axis travel is 800mm, the Y-axis travel is 600mm, and the Z-axis travel is 200mm; it is driven by a stepper motor and equipped with an encoder to achieve closed-loop control. The worktable is equipped with a matrix positioning slot, and a single cycle includes: origin reset → coordinate positioning → Z-axis pressing down → valve opening (0.5-2 seconds) → weighing verification → Z-axis lifting → coordinate stepping.

[0048] The above embodiments are merely one implementation of this utility model and do not constitute a limitation. Any simple modifications, alterations, substitutions, combinations, or simplifications made without departing from the spirit and essence of this utility model are equivalent substitutions and should be within the protection scope of this utility model.
