Description

Technical Field

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

[0002] A crystal resonator is a frequency control element made using the piezoelectric effect of quartz crystals. It consists of a quartz crystal wafer, electrodes, a support, and a package. When a voltage is applied to the two poles of the quartz crystal wafer, the wafer will generate mechanical vibration, and the vibration will generate voltage. This electromechanical conversion has high stability and precision. It is widely used in communication base stations, smartphones, automotive electronics, Internet of Things devices and other fields. The crystal resonator pressing device is the core equipment for achieving precise crystal assembly. Through mechanical transmission and pressure control system, the crystal chip and the packaged components are tightly bonded together.

[0003] However, most existing pressing devices have clamps or contact surfaces that are not smooth enough and have sharp edges and corners. During the clamping process, they can cause scratches, indentations and other damage to the crystal resonator’s shell or wafer surface. These damages may destroy the structural integrity of the crystal and cause potential defects such as microcracks, making the crystal resonator prone to performance degradation or even failure in subsequent use. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in the existing technology, most pressing devices have insufficiently smooth surfaces or sharp edges on the clamps or contact parts, which cause scratches, indentations and other damage to the shell or wafer surface of the crystal resonator during the clamping process. These damages may destroy the structural integrity of the crystal, cause potential defects such as microcracks, and make the crystal resonator prone to performance degradation or even failure in subsequent use. Therefore, this invention proposes a pressing device for crystal resonators.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a crystal resonator pressing device, comprising a base and a protective device. A cylinder is fixedly connected to the upper surface of the base, and a pressure rod is fixedly installed at the driving end of the cylinder. The protective device is disposed on the surface of the base and includes a support rod, which is fixedly connected to the base. An assembly table is fixedly connected to the upper surface of the support rod. A rectangular groove is formed on the surface of the assembly table, and an air cavity is formed on the inner wall of the assembly table. An air compressor is fixedly connected to one side of the base, and an air pipe is fixedly connected to the driving end of the air compressor. The end of the air pipe away from the air compressor is fixedly connected to the assembly table. By setting up the protective device, dual fixing and buffer protection of the crystal resonator are achieved. The initial fixing of the magnetic plate can quickly position the crystal resonator and prevent it from moving randomly during placement. The expansion of the airbag, combined with the flexible clamping of the rubber pad, reduces rigid contact damage to the crystal and can adaptively adjust the clamping force according to the crystal size. During the pressing process, the pressure is effectively buffered, reducing crystal damage caused by external impact and ensuring pressing accuracy and crystal performance.

[0006] Preferably, the air tube is connected to the air chamber, and an airbag is fixedly connected to the inner wall of the rectangular groove. The airbag is connected to the air chamber. By setting the airbag, the air machine drives the airflow through the air tube into the air chamber and then into the airbag. The airbag expands and squeezes the rubber pad. The rubber pad contacts the crystal resonator and completes the clamping. This flexible clamping method can avoid damage to the crystal resonator caused by rigid clamping and reduce the risk of physical damage caused by excessive clamping force.

[0007] Preferably, a rubber pad is fixedly connected to the end of the airbag away from the assembly table, and there are two airbags arranged symmetrically.

[0008] Preferably, a magnetic suction plate is fixedly connected to the inner wall of the rectangular groove. The surface of the magnetic suction plate has a circular hole. By setting the magnetic suction plate, the crystal resonator placed in the rectangular groove is initially fixed by magnetic force. This allows the crystal resonator to be stabilized in a general position before the airbag expands and squeezes the rubber pad to further clamp the crystal resonator.

[0009] Preferably, one end of the assembly table is provided with a part-picking component, which includes a rod that is slidably connected to the assembly table. By setting up the part-picking component, the part-picking time is greatly shortened. The spring reset design allows the rod to automatically return to its original position, preparing for the next part-picking, realizing continuous and efficient operation, reducing labor intensity, reducing the risk of crystal collisions that may be caused by manual part-picking, and improving the smoothness of the overall production process and product yield.

[0010] Preferably, a push block is fixedly connected to one end of the rod, and the surface of the push block is provided with anti-slip texture.

[0011] Preferably, a spring is fitted on the surface of the rod, and the two ends of the spring are fixedly connected to the push block and the assembly table, respectively. By setting the spring, when the push block is pushed to drive the rod to push out the processed crystal resonator, the push block is released and the spring will generate elastic force to squeeze the rod back to its initial position so that the next part picking operation can be carried out smoothly. This realizes the recycling of the part picking component and improves the efficiency and convenience of part picking.

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

[0013] 1. In this utility model, by setting a protective device, when pressing the crystal resonator, the crystal resonator is placed in a rectangular slot, and the magnetic plate magnetically attracts the crystal resonator to initially fix it. Then, an air blower drives airflow through an air pipe into the air chamber, and then through the air chamber into the air bag. The air bag expands and squeezes the rubber pad to clamp the crystal resonator. Then, the cylinder drives the pressure rod to perform the pressing operation on the crystal resonator. By setting a protective device, the crystal resonator is double fixed and buffered. The initial fixation of the magnetic plate can quickly position the crystal resonator and prevent it from moving at will during placement. The expansion of the air bag, combined with the flexible clamping of the rubber pad, reduces rigid contact damage to the crystal and can adaptively adjust the clamping force according to the crystal size. During the pressing process, the pressure is effectively buffered, reducing crystal damage caused by external impact and ensuring pressing accuracy and crystal performance.

[0014] 2. In this utility model, by setting up a part-retrieving component, after the crystal resonator is pressed, the push block is pushed, and the push block drives the rod to push out the processed crystal resonator. The rod is then released, and the spring squeezes the rod to reset, which facilitates the quick removal of the crystal resonator from the rectangular slot. By setting up the part-retrieving component, the part-retrieving time is greatly shortened. The spring reset design allows the rod to automatically return to its original position, preparing for the next part-retrieving operation. This enables continuous and efficient operation, reduces labor intensity, reduces the risk of crystal collisions that may occur during manual part-retrieving, and improves the smoothness of the overall production process and the product yield.

[0021] Please see Figures 1-5 This utility model provides a technical solution: a pressing device for a crystal resonator, including a base 1 and a protective device 4. A cylinder 2 is fixedly connected to the upper surface of the base 1, and a pressure rod 3 is fixedly installed at the driving end of the cylinder 2. The protective device 4 is disposed on the surface of the base 1.

[0022] In this implementation scheme: the protective device 4 includes a support rod 43, which is fixedly connected to the base 1. An assembly table 44 is fixedly connected to the upper surface of the support rod 43. A rectangular groove 48 is opened on the surface of the assembly table 44, and an air cavity 410 is opened on the inner wall of the assembly table 44. An air machine 41 is fixedly connected to one side of the base 1. An air pipe 42 is fixedly connected to the drive end of the air machine 41. The end of the air pipe 42 away from the air machine 41 is fixedly connected to the assembly table 44. By setting the protective device 4, the crystal resonator is double fixed and buffered. The magnetic plate 47 initially fixes and can quickly position the crystal resonator to prevent it from moving randomly during placement. The airbag 45 expands and works with the flexible clamping of the rubber pad 46 to reduce rigid contact damage to the crystal. It can also adaptively adjust the clamping force according to the crystal size, effectively buffering the pressure during the pressing process, reducing crystal damage caused by external impact, and ensuring pressing accuracy and crystal performance.

[0023] Specifically, the trachea 42 is connected to the air chamber 410, and an airbag 45 is fixedly connected to the inner wall of the rectangular groove 48. The airbag 45 is connected to the air chamber 410. By setting the airbag 45, the air pump 41 drives the airflow through the trachea 42 into the air chamber 410 and then into the airbag 45. The airbag 45 expands and squeezes the rubber pad 46. The rubber pad 46 contacts the crystal resonator and completes the clamping. This flexible clamping method can avoid damage to the crystal resonator caused by rigid clamping and reduce the risk of physical damage caused by excessive clamping force.

[0024] Specifically, a rubber pad 46 is fixedly connected to the end of the airbag 45 away from the assembly table 44. There are two airbags 45, and the two airbags 45 are arranged symmetrically.

[0025] Specifically, a magnetic suction plate 47 is fixedly connected to the inner wall of the rectangular groove 48. The surface of the magnetic suction plate 47 has a round hole. By setting the magnetic suction plate 48, the crystal resonator placed in the rectangular groove 48 is initially fixed by magnetic force. This allows the crystal resonator to be stabilized in a general position before the airbag 45 expands and squeezes the rubber pad 46 to further clamp the crystal resonator.

[0026] Specifically, one end of the assembly table 44 is provided with a part picking assembly 49, which includes a rod 493 that is slidably connected to the assembly table 44.

[0027] In this embodiment: by setting up the picking component 49, the picking time is greatly shortened. The spring 492 reset design makes the rod 493 automatically return to its original position, preparing for the next picking, realizing continuous and efficient operation, reducing labor intensity, reducing the risk of crystal collision caused by manual picking, and improving the smoothness of the overall production process and product yield.

[0028] Specifically, a push block 491 is fixedly connected to one end of the rod 493, and the surface of the push block 491 is provided with anti-slip texture.

[0029] Specifically, a spring 492 is fitted onto the surface of the rod 493, and the two ends of the spring 492 are fixedly connected to the push block 491 and the assembly table 44, respectively.

[0030] In this embodiment: by setting a spring 492, when the push block 491 drives the rod 493 to push out the processed crystal resonator, the push block 491 is released, and the spring 492 will generate elastic force, squeezing the rod 3 to return it to its initial position, so that the next part picking operation can be carried out smoothly. This realizes the cyclic use of the part picking assembly 49 and improves the efficiency and convenience of part picking.

[0031] Working principle: By setting up the protective device 4, when pressing the crystal resonator, the crystal resonator is placed in the rectangular slot 48. The magnetic plate 47 magnetically attracts the crystal resonator to initially fix it. Then, the air blower 41 drives the airflow through the air pipe 42 into the air chamber 410, and then through the air chamber 410 into the air bag 45. The air bag 45 expands and squeezes the rubber pad 46 to clamp the crystal resonator. Then, the cylinder 2 drives the pressure rod 3 to perform the pressing operation on the crystal resonator. By setting up the protective device 4, the crystal resonator is double fixed and buffered. The initial fixation of the magnetic plate 47 can quickly position the crystal resonator and prevent it from moving at will during placement. The expansion of the air bag 45, combined with the flexible clamping of the rubber pad 46, reduces rigid contact damage to the crystal and can adaptively adjust the clamping force according to the crystal size. It effectively buffers the pressure during the pressing process, reduces crystal damage caused by external impact, and ensures pressing accuracy and crystal performance.

[0032] By setting up the part-retrieving component 49, after the crystal resonator is pressed, the push block 491 is pushed, and the push block 491 drives the rod 493 to push out the processed crystal resonator. The rod 493 is released, and the spring 492 squeezes the rod 3 to reset, which facilitates the quick removal of the crystal resonator from the rectangular slot 48. By setting up the part-retrieving component 49, the part-retrieving time is greatly shortened. The reset design of the spring 492 makes the rod 493 automatically return to its original position, preparing for the next part-retrieving operation, realizing continuous and efficient operation, reducing labor intensity, reducing the risk of crystal collision caused by manual part-retrieving, and improving the smoothness of the overall production process and product yield.
