Description

Technical Field

[0001] This utility model relates to the field of vibration feeding technology, and in particular to a feeding device for a quartz crystal resonator. Background Technology

[0002] A quartz crystal resonator is an electronic component that utilizes the inverse piezoelectric effect of quartz crystal material to generate high-precision oscillation frequencies. Quartz crystal resonators are widely used in electronic devices such as oscillators, timers, clock circuits, and wireless communication systems to ensure accurate timing and frequency stability.

[0003] Before quartz crystal resonators can enter the testing, marking, inspection, and packaging processes, they need to be transported to the corresponding work areas using a feeding device. However, existing feeding devices struggle to accurately directionally transport quartz crystal resonators with their faces facing up. This results in some quartz crystal resonators with their faces facing down being mixed into subsequent processes, negatively impacting the accuracy of testing, the standardization of marking, the reliability of inspection, and the efficiency of packaging, thus reducing overall production efficiency and the stability of product quality. Utility Model Content

[0004] To address the aforementioned shortcomings, this invention proposes a feeding device for a quartz crystal resonator.

[0005] The technical solution adopted in this utility model is a feeding device for a quartz crystal resonator, comprising:

[0006] hopper;

[0007] A spiral feed rail is provided on the inner wall of the hopper. The spiral feed rail includes an air blowing section, and the bottom width of the air blowing section is smaller than the bottom width of the other sections of the spiral feed rail.

[0008] Air nozzle one, the air nozzle one is directly facing the air blowing section towards the inner bottom of the hopper and continuously blows air, the quartz crystal resonator facing down is blown down to the inner bottom of the hopper by the air nozzle one in the air blowing section.

[0009] The optical fiber for detecting front and back sides is used to detect the front and back sides of the quartz crystal resonator on the spiral rail. When the quartz crystal resonator facing down is detected, the optical fiber for detecting front and back sides sends out an air blowing command.

[0010] Air nozzle two is located downstream of the front and back detection optical fiber. Air nozzle two blows air towards the inner bottom of the hopper from the spiral feed rail according to the air blowing command.

[0011] Furthermore, the air blowing section can be replaced and installed on the hopper.

[0012] Furthermore, the bottom surface of the spiral feed rail, in the portion not of the air blowing section, is provided with anti-slip texture.

[0013] Furthermore, it also includes:

[0014] An air regulating valve is connected to air nozzle one and air nozzle two respectively, and is used to regulate the on / off and magnitude of the airflow of air nozzle one and air nozzle two;

[0015] An amplifying optical fiber is connected to the front and back detection optical fibers and is used to amplify the signals transmitted by the front and back detection optical fibers.

[0016] Furthermore, it also includes a cleaning structure, wherein the hopper has a discharge port, and the cleaning structure includes a baffle and a driving component, wherein the driving component drives the baffle to open or close the discharge port.

[0017] Furthermore, the cleaning structure also includes a suction nozzle, an air pipe, and a material box disposed on the outside of the hopper. The suction nozzle is directly facing the discharge port to draw air, and the material box is connected to the material box through the air pipe.

[0018] Furthermore, it also includes a linear flat rail, one end of which is connected to the output end of the spiral feed rail, and the other end is the output end of the feeding device. The flat rail conveys the quartz crystal resonator through vibration. An acceleration mechanism is also provided in the middle section of the flat rail. The acceleration mechanism provides airflow to impact the quartz crystal resonator to accelerate the conveying of the quartz crystal resonator.

[0019] Furthermore, a positioning detection fiber is provided at the end of the flat rail away from the spiral material rail. The positioning detection fiber is used to detect whether the quartz crystal resonator is on the end of the flat rail away from the spiral material rail.

[0020] Furthermore, the flat rail is also equipped with a material separation and acceleration air blowing device, which is located between the acceleration mechanism and the positioning detection fiber, and close to the positioning detection fiber. The material separation and acceleration air blowing device can drive the quartz crystal resonator upstream of the positioning detection fiber to be transported quickly.

[0021] Furthermore, the flat rail is also equipped with a full-material detection fiber and a short-material detection fiber. The full-material detection fiber is located at one end of the flat rail near the spiral material rail and is used to detect whether the quartz crystal resonator is piled up. The short-material detection fiber is located between the acceleration mechanism and the material separation acceleration blowing device and is used to detect the presence or absence of the quartz crystal resonator.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] By using air nozzles one and two in combination, along with the precise detection of the optical fiber for front and back detection, quartz crystal resonators facing down can be effectively screened out. This ensures that the quartz crystal resonators sent to subsequent processes are facing up. During subsequent marking, testing, and packaging operations, the more standardized initial state of the materials (uniform front and back) reduces problems such as marking errors, test data deviations, and irregular packaging caused by inconsistencies in the front and back of the quartz crystal resonators. This improves the consistency of product quality and production efficiency throughout the entire production process. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0028] In one embodiment, a feeding device for a quartz crystal resonator is described in [reference needed]. Figure 1 The system includes a hopper 110, a spiral feed rail 120, and an air nozzle 112. The hopper 110 is used to store and initially disperse the quartz crystal resonator so that it can be conveyed to the spiral feed rail 120. The hopper 110 is designed as a funnel shape with a smooth inner wall to reduce blockage during vibration. At the same time, a disc vibration mechanism 115 is connected to its inner bottom. The disc vibration mechanism 115 can provide piezoelectric frequency vibration to drive the material movement in the hopper 110, thereby vibrating the quartz crystal resonator into the spiral feed rail 120. The hopper 110 is generally made of a metal material (such as stainless steel) with certain strength and wear resistance to withstand the friction of the quartz crystal resonator and the long-term vibration working environment.

[0029] The spiral feed rail 120 is used to transport quartz crystal resonators one by one. It is arranged close to the inner wall of the hopper 110 and spirals upward around the inner wall of the hopper 110 to gradually lift the quartz crystal resonators and move them in an orderly manner to a specific output position. The spiral feed rail 120 consists of a bottom surface and a side surface. The side surface supports one side of the quartz crystal resonator and carries and guides the quartz crystal resonator along the spiral trajectory. The angle between the side surface and the horizontal plane is obtuse, so that the quartz crystal resonator can lean more smoothly against the side of the spiral rail and be transported stably. The bottom surface of the spiral feed rail 120 is inclined at a 40-45 degree angle. The quartz crystal resonator is subjected to gravity on this inclined surface. Gravity can be decomposed into two components: one perpendicular to the bottom surface of the feed rail and the other parallel to it. The component parallel to the bottom surface provides a driving force for the quartz crystal resonator in the spiral upward direction, making it easier to move upward along the spiral feed rail 120 with the vibration assistance of the vibration mechanism. This natural gravity-driven method reduces dependence on vibration intensity, making material conveying more stable and smooth. The bottom width of the spiral feed rail 120 is designed according to the thickness of the quartz crystal resonator, for example, set to 0.6mm-0.7mm.

[0030] A section of the spiral feed rail 120 along its circumference is designated as an air-blowing section. Air nozzle 112 continuously blows air into this section towards the inner bottom of the hopper 110. The front of a quartz crystal resonator is typically flat, and may even be polished to ensure smoothness. The back of the quartz crystal resonator, however, contains other functional structures such as mounting brackets or additional electrodes, resulting in higher roughness. Therefore, when subjected to the same airflow, the force on the back of the quartz crystal resonator is greater than that on its front. By adjusting the airflow size of air nozzle 112, quartz crystal resonators facing upwards can pass smoothly through the air-blowing section of the spiral rail without being blown off. Quartz crystal resonators facing downwards fall from the air-blowing section into the inner bottom of the hopper 110 under the force of air from nozzle 112. This ensures, to a certain extent, that the quartz crystal resonators output by the self-feeding device are facing upwards, facilitating subsequent testing, marking, inspection, and packaging. Among them, the air nozzle 112 is usually connected to an external air source, which can provide a stable and adjustable airflow with adjustable pressure and flow rate to meet the screening requirements of quartz crystal resonators of different sizes, weights and other characteristics.

[0031] Furthermore, the bottom width of the air blowing section is smaller than the bottom width of other sections of the spiral feed rail 120, which reduces the support area of ​​the bottom surface of the quartz crystal resonator when it passes through the air blowing section, making it relatively weaker and more susceptible to the influence of external airflow. This creates favorable conditions for distinguishing the front and back of the quartz crystal resonator through the air nozzle 112.

[0032] Furthermore, the feeding device for the quartz crystal resonator also includes a front / back detection fiber optic cable 111 and an air nozzle 2. The front / back detection fiber optic cable 111 is installed along the path of the spiral feed rail 120 and is used to detect the front and back of the quartz crystal resonator moving on the spiral feed rail 120. The front / back detection fiber optic cable 111 emits light of a specific wavelength and receives the light reflected back from the surface of the quartz crystal resonator. It can determine the front and back of the quartz crystal resonator by utilizing the difference in reflected light between the front (usually relatively smooth and flat) and the back (with functional structures and higher roughness). When a quartz crystal resonator facing down is detected, a blowing command is quickly issued, triggering the operation of the subsequent air nozzle 2, to further screen the quartz crystal resonators facing down that were not blown off during the blowing section. The front / back detection fiber optic cable 111 has high detection accuracy and fast response capability to ensure accurate judgment during the rapid movement of the quartz crystal resonator.

[0033] Air nozzle two is located downstream of the front / back detection fiber optic cable 111. It operates according to the air blowing command issued by the fiber optic cable 111. Once a command is received, air nozzle two blows air towards the bottom of the hopper 110 from the spiral feed rail 120, further screening the quartz crystal resonators that have passed through this area and are face down, blowing them down to the bottom of the hopper 110. This further increases the probability that all output quartz crystal resonators are face up, ensuring that the quartz crystal resonators sent to subsequent processes (such as marking, testing, packaging, etc.) meet the specific front / back requirements. Air nozzle two is also connected to an external air source, and its blowing intensity, angle, and other parameters can be adjusted appropriately according to actual production conditions.

[0034] In this feeding device, the airflow parameters (such as pressure and flow rate) of air nozzles 112 and 112, as well as the detection sensitivity of the front and back detection fiber optic cable 111, can be adjusted according to different models and specifications of quartz crystal resonators. This allows the device to adapt to the feeding needs of various types of quartz crystal resonators. When facing different production orders and product requirements, there is no need to replace the entire set of equipment; only simple parameter adjustments are required before it can be put into use, enhancing the applicability and flexibility of the equipment in actual production.

[0035] By combining air nozzles 112 and 112, and with the precise detection of the front and back detection fiber optic cable 111, quartz crystal resonators facing down can be effectively screened out, ensuring that the quartz crystal resonators sent to subsequent processes are facing up. During subsequent marking, testing, and packaging operations, the more standardized initial state of the materials (uniform front and back) reduces problems such as marking errors, test data deviations, and irregular packaging caused by inconsistencies in the front and back of the quartz crystal resonators, thus improving the consistency of product quality and production efficiency throughout the entire production process.

[0036] In other embodiments, there can be multiple air nozzles 112, front and back detection optical fiber 111, and air nozzle 2. The front and back of the quartz crystal resonator are detected multiple times, and the quartz crystal resonator with the back facing up is blown into the return hopper 110 multiple times to ensure that the quartz crystal resonator output from the output end of the feeding device is always front facing up.

[0037] In one embodiment, the air-blowing section is replaceably mounted on the hopper 110. The air-blowing section is a detachable part of the spiral feed rail 120, connected to its mounting position on the hopper 110 via a specific connection method. For example, the air-blowing section can use a slot-type connection; a slot is provided at a corresponding position on the hopper 110, and a locking block is provided on the edge of the air-blowing section. Inserting the locking block into the slot secures the section. This connection method facilitates the installation and removal of the air-blowing section. According to production requirements, a suitable air-blowing section is selected and installed on the hopper 110. During installation, the locking block of the air-blowing section is inserted into the corresponding slot on the hopper 110 to ensure a tight connection between the air-blowing section and the hopper 110. When it is necessary to replace quartz crystal resonators of different specifications or types, the air-blowing section is disassembled and removed from the hopper 110, and then a new air-blowing section is installed. This allows adjustment of the air-blowing section parameters, such as bottom width and blowing angle, according to the characteristics of different quartz crystal resonators, thereby improving the accuracy and efficiency of screening.

[0038] In one embodiment, the bottom surface of the non-blowing section of the spiral feed rail 120 is provided with anti-slip textures. These textures can be regular stripes or a grid pattern, and are manufactured using laser etching or molding processes, tightly bonded to the bottom surface of the spiral feed rail 120. The depth and width of the anti-slip textures are designed according to the size and material characteristics of the quartz crystal resonator, ensuring that friction is effectively increased without affecting the normal operation of the feed rail. This prevents the quartz crystal resonator from sliding or rolling during vibration, allowing it to move smoothly along the spiral track, reducing collisions and damage caused by unstable material movement, minimizing material accumulation, reducing the possibility of blockage, and ensuring the continuity of the production process.

[0039] In one embodiment, the feeding device for the quartz crystal resonator further includes an air blowing regulating valve 113 and an amplifying optical fiber 114. The air blowing regulating valve 113 is connected to air nozzle 112 and air nozzle 2, respectively. The air blowing regulating valve 113 can adjust the airflow interruption and airflow magnitude of air nozzles 112 and 112 through manual or automatic control. This allows air nozzles 112 and 112 to blow air onto the quartz crystal resonator more effectively, improving the blowing effect and ensuring that the face-down quartz crystal resonator can be blown down to the bottom of the hopper 110.

[0040] The amplifying fiber 114 connects to the front / back detection fiber 111 and amplifies the signal transmitted by the front / back detection fiber 111. When the quartz crystal resonator moves on the spiral guide 120, the signal emitted by the front / back detection fiber 111 may be weak, making it difficult to accurately determine the front / back of the quartz crystal resonator. The amplifying fiber 114 amplifies the signal, increasing its intensity and thus improving the accuracy of the detection. The amplifying fiber 114 can adjust the signal amplification factor according to the characteristics of the quartz crystal resonator and the detection requirements. For example, for some small quartz crystal resonators, the amplifying fiber 114 can amplify the signal to a sufficient intensity for more accurate detection of its front / back.

[0041] In one embodiment, the feeding device for the quartz crystal resonator further includes a cleaning structure 137. The hopper 110 has a discharge port, which can be located on the side wall or bottom. The position, size, and shape of the discharge port can be designed according to actual production needs. The cleaning structure 137 includes a baffle and a driving component. The baffle is typically made of metal, such as stainless steel, to ensure its strength and durability. The edge of the baffle fits tightly against the edge of the discharge port of the hopper 110, ensuring effective prevention of material leakage when the discharge port is closed. The driving component drives the baffle to open or close the discharge port. The driving component can be an electric motor, a cylinder, or other power device. For example, the electric motor is connected to the baffle via a connecting shaft. When the electric motor starts, the shaft rotates, causing the baffle to rotate, thereby opening the discharge port. The driving component is connected to a control system, enabling control of the baffle's movement according to production needs.

[0042] When it is necessary to replace quartz crystal resonators with different parameters or from different batches, the drive unit receives a command from the control system to activate the drive baffle, opening the discharge port. The quartz crystal resonators in hopper 110 are then discharged through the discharge port. The baffle can open by rotation, translation, or other methods, depending on the design of the drive unit and the structure of hopper 110. During the cleaning process, the drive unit can control the degree of baffle opening to control the flow rate and speed of the material. After cleaning is complete, the drive unit receives a command from the control system to close the baffle, sealing the discharge port. Once the baffle is closed, the material in hopper 110 is sealed, preventing leakage.

[0043] In one embodiment, the cleaning structure further includes a suction nozzle, an air pipe, and a material box disposed on the outside of the hopper 110. The suction nozzle is positioned directly opposite the discharge port to draw air in. The suction nozzle has a relatively flat design to ensure a tight fit with the discharge port and to guarantee an effective seal during suction. The suction nozzle is typically made of rubber or plastic, possessing good flexibility and sealing properties to prevent air leakage. The air pipe connects the suction nozzle and the material box, providing a passage for air. The air pipe is generally made of rubber or plastic, possessing a certain degree of flexibility and strength, and capable of withstanding a certain negative pressure. Its inner diameter is selected based on the suction volume of the suction nozzle and the capacity of the material box, generally between 1 and 5 centimeters. The material box is used to collect the quartz crystal resonators drawn from the discharge port of the hopper 110. The material box is typically made of plastic or metal, possessing a certain degree of strength and corrosion resistance. The shape and size of the material box are designed according to actual needs, generally a cuboid or cylinder, capable of accommodating a certain number of quartz crystal resonators. The material box may be equipped with an openable and closable lid.

[0044] When the cleaning mechanism is activated, the suction nozzle begins to draw in air, creating a negative pressure at the outlet of hopper 110. Due to the pressure difference between the quartz crystal resonator inside hopper 110 and the outside atmosphere, the quartz crystal resonator is drawn out of hopper 110 under the action of negative pressure. The suction nozzle draws the quartz crystal resonator into the air pipe, and then transports it to the material box through the air pipe. A certain shock absorption device can be installed inside the material box to prevent damage to the quartz crystal resonator during the suction process.

[0045] In other embodiments, the cleaning structure 137 may also be configured with other structures.

[0046] In one embodiment, the feeding device for the quartz crystal resonator further includes a flat rail 130. One end of the flat rail 130 is connected to the output end of the spiral feed rail 120, and the other end is the output end of the feeding device. The flat rail 130 conveys the quartz crystal resonator through vibration. The flat rail 130 is configured as a straight line to ensure that the quartz crystal resonator can be conveyed stably and orderly. The portion of the flat rail 130 that connects to the spiral feed rail 120 gradually becomes level along the output end of the spiral feed rail 120 until it is horizontal. The flat rail 130 is driven by piezoelectric frequency vibration provided by the flat rail vibration mechanism 136 to move the material within the flat rail 130.

[0047] Furthermore, an acceleration mechanism 135 is installed in the middle section of the flat rail 130. When the material movement within the flat rail 130 is not smooth or slow, the acceleration mechanism 135 can be activated to blow air onto the flat rail 130. The jet of air propels the material, enabling it to move faster on the flat rail 130, thereby solving the problem of material accumulation or slow movement. The airflow speed ejected by the acceleration mechanism 135 can be adjusted according to the size of the quartz crystal resonator and the conveying requirements, generally between 5 and 20 meters per second.

[0048] In one embodiment, a positioning detection fiber optic cable 131 is installed at the end of the flat rail 130 away from the spiral feed rail 120. The positioning detection fiber optic cable 131 is used to detect whether a quartz crystal resonator is present on the end of the flat rail 130 away from the spiral feed rail 120. When the positioning detection fiber optic cable 131 detects a quartz crystal resonator on the flat rail 130, subsequent testing stations begin to remove the quartz crystal resonator from the flat rail 130; when the positioning detection fiber optic cable 131 does not detect any material, subsequent testing stations stop working and enter a waiting state. The positioning detection fiber optic cable 131 can determine whether the material has accurately reached the designated position, providing important information for subsequent production processes.

[0049] In one embodiment, a material separation and acceleration air blowing device 132 is also provided on the flat rail 130. The material separation and acceleration air blowing device 132 is located between the acceleration mechanism 135 and the positioning detection fiber optic cable 131, and is positioned close to the positioning detection fiber optic cable 131. The material separation and acceleration air blowing device 132 can drive the quartz crystal resonator upstream of the positioning detection fiber optic cable 131 to transport the material quickly. When the material reaches the designated position on the flat rail 130, the material separation and acceleration air blowing device 132 is activated to quickly position the material so that the positioning detection fiber optic cable 131 can detect the material, ensuring that subsequent workstations can operate continuously and without interruption, thereby improving production efficiency.

[0050] In one embodiment, the flat rail 130 may also be equipped with a full-material detection fiber optic cable 133 and a short-material detection fiber optic cable 134. The full-material detection fiber optic cable 133 is located at one end of the flat rail 130 near the spiral feed rail 120 and is used to detect whether the quartz crystal resonators are piled up. The short-material detection fiber optic cable 134 is located between the acceleration mechanism 135 and the material separation acceleration blowing device 132 and is used to detect the presence or absence of quartz crystal resonators. When the full-material detection fiber optic cable 133 detects that the flat rail 130 is full of quartz crystal resonators, the spiral feed rail 120 stops conveying material to the flat rail 130, and the flat rail 130 continues to convey material to the subsequent station. When the short-material detection fiber optic cable 134 detects that the material in the flat rail 130 is sparse, the spiral feed rail 120 and the flat rail 130 accelerate until the full-material fiber optic cable detects material. The full material detection fiber 133 and the short material detection fiber 134 can detect the full material and short material status of the flat rail 130 in a timely manner, preventing excessive accumulation of materials on the flat rail 130 or collisions and wear caused by material shortage, thus ensuring product quality.
