Description

Technical Field

[0001] This utility model relates to the field of crystal resonator technology, and in particular to a sieve machine for producing crystal resonators. Background Technology

[0002] A crystal resonator is an electronic component that utilizes the piezoelectric effect of quartz crystals to achieve frequency selection and stabilization. Under the action of an electric field, a quartz crystal can generate mechanical vibration, and conversely, mechanical vibration can also generate an electric field. When the frequency of the applied electric field matches the natural vibration frequency of the crystal, resonance occurs, and a stable frequency signal is output. The tableting process in the production of crystal resonators requires pressing granular raw materials into tablets. Due to uneven contact between the raw materials and the tableting machine, the pressed tablets often have problems such as fragments, micro-cracks that are easy to break, and residual edges, resulting in a large number of unqualified products.

[0003] However, in the existing crystal resonator pressing and screening process, due to the accumulation of a large number of pressed sheets, the screening operation is difficult to fully cover each pressed sheet, which easily leads to omissions. Insufficient screening makes it impossible to completely detect defective products, which are mixed with qualified products, affecting the overall quality of the product and its subsequent performance, increasing the difficulty of quality control and potential after-sales risks. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the existing crystal resonator pressing and screening process, where a large number of pressed sheets pile up, making it difficult to fully cover each pressed sheet during screening, easily leading to omissions. Insufficient screening results in defective products not being completely detected, thus mixing with qualified products, affecting the overall product quality and subsequent performance, increasing the difficulty of quality control and potential after-sales risks. Therefore, this invention proposes a crystal resonator pressing and screening machine.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a screening machine for producing crystal resonators, comprising a machine body, a filter plate fixedly connected to the upper surface of the machine body, a support fixedly connected to one side of the machine body, a motor fixedly connected to the surface of the support, a drive end of the motor passing through the machine body and fitted with a transmission belt, a frame fixedly connected to the upper surface of the support, a cylinder fixedly connected to the lower surface of the frame, a telescopic rod fixedly connected to the drive end of the cylinder passing through the frame, a baffle fixedly connected to the lower surface of the telescopic rod, the baffle being slidably connected to the frame, and a protrusion fixedly connected to one end of the support. By designing this utility model, the transmission belt guides, and the buffer plate and torsion spring work together to buffer, effectively reducing the impact force of the falling crystal resonator plates and minimizing damage caused by impact. The inclined design of the filter plate enables automatic separation of qualified and unqualified plates. The cylinder-driven telescopic rod squeezes the baffle to discharge materials in segments, reducing the accumulation of large amounts of plates and improving screening efficiency and accuracy.

[0006] Preferably, the surface of the protrusion has a through hole, and a rocker arm is rotatably connected to the surface of the protrusion. By setting the rocker arm, it is easy to drive the buffer plate to rotate, and cooperate with the torsion spring to buffer the impact force of the falling pressure plate.

[0007] Preferably, a buffer plate is fixedly connected to the surface of the rocker arm. The buffer plate is inclined. By setting the buffer plate, when the crystal resonator plate is guided to fall by the transmission belt, the elastic force generated by the torsion spring, together with its own structure, buffers the impact force generated by the falling plate, reducing the damage to the plate due to the large impact force. At the same time, it creates conditions for the plate to fall smoothly onto the filter plate, ensuring the smooth progress of the screening process.

[0008] Preferably, a torsion spring is fitted on the surface of the rocker arm, and the two ends of the torsion spring are fixedly connected to the protrusion and the buffer plate, respectively. By setting the torsion spring, when the crystal resonator plate falls onto the buffer plate, it is subjected to force to generate elastic force, which works with the buffer plate to buffer the impact force generated by the falling plate, thereby reducing the possibility of the plate being damaged by the falling impact and protecting the quality of the plate.

[0009] Preferably, the machine body is equipped with a recycling component, which includes a slide rod that is slidably connected to the machine body. A push plate is fixedly connected to one side of the slide rod. By setting up the recycling component, after screening, the slide rod and push plate can be pushed by pushing the pull rod to smoothly push out the unqualified tablets inside the machine body, which facilitates centralized recycling and processing, reduces manual operation, improves recycling efficiency, and reduces the accumulation of unqualified tablets that may affect subsequent production processes.

[0010] Preferably, the push plate is located in the inner wall of the machine body and is slidably connected to the machine body. By setting the push plate, after the crystal resonator pressing and screening is completed, when the pull rod is pushed to make the slide rod slide, the slide rod drives the push plate to move. The push plate squeezes the unqualified pressing plates inside the machine body and makes them slide out of the machine body, so as to realize the recycling of unqualified pressing plates.

[0011] Preferably, a pull rod is fixedly connected to the upper surface of the slide bar, and the length of the push plate is consistent with the inner diameter of the machine body.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, during use, the crystal resonator pressing tablets are transported by a transmission belt. Guided by the transmission belt, the pressing tablets fall onto a buffer plate. The torsion spring generates elastic force, which, together with the buffer plate, buffers the impact force generated by the falling pressing tablets. Subsequently, the pressing tablets fall onto a filter plate after passing through the buffer plate. Because the filter plate is inclined, qualified pressing tablets pass through the filter plate, while unqualified pressing tablets fall into the machine body. When the transmission belt guides the pressing tablets, the cylinder drives the telescopic rod to squeeze the baffle to block the pressing tablets, which facilitates segmented feeding and reduces the accumulation of a large number of pressing tablets at the same time. By setting up this utility model, the transmission belt guides, and the buffer plate and torsion spring work together to effectively reduce the impact force of the falling crystal resonator pressing tablets and reduce the damage caused by the impact. The inclined design of the filter plate realizes the automatic separation of qualified and unqualified pressing tablets. The cylinder drives the telescopic rod to squeeze the baffle to feed the pressing tablets in segments, reducing the accumulation of a large number of pressing tablets and improving the screening efficiency and accuracy.

[0014] 2. In this utility model, by setting up a recycling component, after screening is completed, the pull rod is pushed, the pull rod squeezes the slide bar to slide, the slide bar moves and drives the push plate, the push plate squeezes the unqualified tablets inside the machine body to slide out, which is convenient for recycling. By setting up a recycling component, after screening is completed, by pushing the pull rod to drive the slide bar and push plate, the unqualified tablets inside the machine body can be smoothly pushed out, which is convenient for centralized recycling, reduces manual operation, improves recycling efficiency, and reduces the accumulation of unqualified tablets that affect subsequent production processes.

[0021] Please see Figures 1-5 This utility model provides a technical solution: a sieve machine for producing crystal resonators.

[0022] This implementation plan includes a machine body 1, a filter plate 2 fixedly connected to the upper surface of the machine body 1, a bracket 3 fixedly connected to one side of the machine body 1, a motor 5 fixedly connected to the surface of the bracket 3, the drive end of the motor 5 passing through the machine body 1 and fitted with a transmission belt 4, a frame 6 fixedly connected to the upper surface of the bracket 3, a cylinder 7 fixedly connected to the lower surface of the frame 6, a telescopic rod 9 fixedly connected to the drive end of the cylinder 7 passing through the frame 6, a baffle 8 fixedly connected to the lower surface of the telescopic rod 9, the baffle 8 being slidably connected to the frame 6, and a protrusion 11 fixedly connected to one end of the bracket 3. By setting up this utility model, the transmission belt 4 guides, the buffer plate 10 and the torsion spring 13 work together to buffer, effectively reducing the impact force of the crystal resonator pressing tablet falling, reducing damage caused by impact, the inclined design of the filter plate 2 realizes automatic separation of qualified and unqualified pressing tablets, and the cylinder 7 drives the telescopic rod 9 to squeeze the baffle 8 to discharge the material in sections, reducing the accumulation of a large number of pressing tablets and improving screening efficiency and accuracy.

[0023] Specifically, the surface of the protrusion 11 is provided with a through hole, and a rocker arm 12 is rotatably connected to the surface of the protrusion 11. By setting the rocker arm 12, it is easy to drive the buffer plate 10 to rotate, and cooperate with the torsion spring 13 to buffer the impact force of the pressure plate falling.

[0024] Specifically, a buffer plate 10 is fixedly connected to the surface of the rocker arm 12. The buffer plate 10 is set at an angle. By setting the buffer plate 10, when the crystal resonator plate is guided to fall by the transmission belt 4, the elastic force generated by the torsion spring 13, together with its own structure, buffers the impact force generated by the falling plate, reducing the damage to the plate due to the large impact force. At the same time, it creates conditions for the plate to fall smoothly to the filter plate 2, ensuring the smooth progress of the screening process.

[0025] Specifically, a torsion spring 13 is fitted on the surface of the rocker arm 12. The two ends of the torsion spring 13 are fixedly connected to the protrusion 11 and the buffer plate 10, respectively. By setting the torsion spring 13, when the crystal resonator plate falls onto the buffer plate 10, it generates elastic force under force, which works with the buffer plate 10 to buffer the impact force generated by the falling plate, thereby reducing the possibility of the plate being damaged by the falling impact and protecting the quality of the plate.

[0026] Specifically, the body 1 is equipped with a recovery assembly 14, which includes a slide bar 143. The slide bar 143 is slidably connected to the body 1, and a push plate 142 is fixedly connected to one side of the slide bar 143.

[0027] In this embodiment: by setting up the recycling component 14, after screening, by pushing the pull rod 141 to drive the slide rod 143 and the push plate 142, the unqualified tablets inside the machine body 1 can be smoothly pushed out, which facilitates centralized recycling and processing, reduces manual operation, improves recycling efficiency, and reduces the accumulation of unqualified tablets that affect subsequent production processes.

[0028] Specifically, the push plate 142 is located in the inner wall of the body 1, and the push plate 142 is slidably connected to the body 1.

[0029] In this embodiment: by setting a push plate 142, after the crystal resonator pressing and screening is completed, when the pull rod 141 is pushed to make the slide rod 143 slide, the slide rod 143 drives the push plate 142 to move, and the push plate 142 squeezes the unqualified pressing plates inside the machine body 1, so as to make them slide out of the machine body 1, so as to realize the recycling of unqualified pressing plates.

[0030] Specifically, a pull rod 141 is fixedly connected to the upper surface of the slide bar 143, and the length of the push plate 142 is consistent with the inner diameter of the body 1.

[0031] Working principle: During use, the crystal resonator tablets are transported by the transmission belt 4. Guided by the transmission belt 4, the tablets fall onto the buffer plate 10. The torsion spring 13 generates elastic force and works with the buffer plate 10 to buffer the impact force of the falling tablets. Subsequently, the tablets fall onto the filter plate 2 after passing through the buffer plate 10. Since the filter plate 2 is inclined, qualified tablets pass through the filter plate 2, while unqualified tablets fall into the machine body 1. When the transmission belt 4 guides the tablets, the cylinder 7 drives the telescopic rod 9 to squeeze the baffle 8 to block the tablets, which facilitates segmented feeding and reduces the accumulation of a large number of tablets at the same time. By setting up this utility model, the transmission belt 4 guides, and the buffer plate 10 and torsion spring 13 work together to buffer, effectively reducing the impact force of the falling crystal resonator tablets and reducing the damage caused by the impact. The inclined design of the filter plate 2 realizes the automatic separation of qualified and unqualified tablets. The cylinder 7 drives the telescopic rod 9 to squeeze the baffle 8 to feed the tablets in segments, reducing the accumulation of a large number of tablets and improving the screening efficiency and accuracy.

[0032] By setting up the recycling component 14, after screening, the pull rod 141 is pushed, and the pull rod 141 squeezes the slide rod 143 to slide. The slide rod 143 moves and drives the push plate 142. The push plate 142 squeezes the unqualified tablets inside the machine body 1 out, which is convenient for recycling. By setting up the recycling component 14, after screening, by pushing the pull rod 141 to drive the slide rod 143 and the push plate 142, the unqualified tablets inside the machine body 1 can be smoothly pushed out, which is convenient for centralized recycling, reduces manual operation, improves recycling efficiency, and reduces the accumulation of unqualified tablets that affect subsequent production processes.
