Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electric cleaning devices, for example to a crystal oscillator electric cleaning device. BACKGROUND

[0002] The description in this section merely provides background information related to the present disclosure and does not constitute prior art.

[0003] As a key component in electronic devices, the frequency stability, precision and reliability of crystal oscillators are crucial to the overall performance of the device. In the production process of crystal oscillators, the electric cleaning process is an important link to ensure its performance. Electric cleaning is mainly used to remove dirt, impurities and oxide layers on the surface of crystal oscillators, which may have a negative impact on the frequency stability, precision and electrical connection performance of crystal oscillators. Through electric cleaning, the reliability and stability of crystal oscillators can be effectively improved, and their electrical connection performance can be improved. However, the electric cleaning device in the prior art usually adopts a socket type side needle operation mode, which has the following problems in actual application: the existing socket type side needle operation mode is worn out during frequent use, and the socket needs to be replaced every 50,000 tests on average. Since the socket itself is expensive, frequent replacement not only increases the cost of equipment maintenance, but also reduces production efficiency. When using the side needle socket, PC (polycarbonate) dust is generated due to friction between the product and the socket. These dusts may adhere to the surface of the crystal oscillator, adversely affecting subsequent testing and operation. SUMMARY

[0004] The present application provides a crystal oscillator electric cleaning device, which directly uses a test probe to stimulate the product on the side, avoiding the friction between the product and the socket in the traditional socket type side needle operation mode. This design fundamentally eliminates the generation of PC (polycarbonate) dust, solving the adverse effects of dust pollution on the surface of the crystal oscillator and subsequent operations. The direct contact between the test probe and the product eliminates the need for a socket as an intermediary, reducing the wear and tear of contact components and further reducing the risk of pollution. The durability of the test probe is significantly better than that of the traditional socket, and its operation frequency can exceed 100,000 times, which is much higher than the 50,000 life of the socket type side needle operation mode. After 100,000 operations, the cost of replacing the probe is less than 10% of the socket, significantly reducing the cost of equipment maintenance. Through the synergistic effect of the three-dimensional adjuster, the X-axis linear drive guide rail, the Z-axis linear drive guide rail and the Y-axis linear drive guide rail, the device can realize accurate positioning and adjustment of the electric cleaning device and the workpiece. The three-dimensional adjuster drives the electric cleaning device to move towards or away from the side of the workpiece, ensuring that the contact position of the test probe and the product is accurately controllable.

[0095] The crystal oscillator electric cleaning device 35 provided by the embodiment of the present disclosure directly uses the test probe 36 to stimulate the product from the side, avoiding the friction between the product and the socket in the traditional socket side needle operation mode. This design fundamentally eliminates the generation of PC (polycarbonate) dust and solves the adverse effects of dust pollution on the surface of the crystal oscillator and subsequent operations. The direct contact between the test probe 36 and the product eliminates the need for a socket as an intermediary, reducing the wear of the contact components and further reducing the risk of pollution. The durability of the test probe 36 is significantly better than that of the traditional socket, and the operation frequency can exceed 100,000 times, which is much higher than the 50,000 times of the socket side needle operation mode. After 100,000 operations, the cost of replacing the probe 36 is less than 10% of the socket, greatly reducing the equipment maintenance cost. Through the coordinated action of the three-dimensional adjuster 32, the X-axis linear drive guide rail 21, the Z-axis linear drive guide rail 29 and the Y-axis linear drive guide rail 25, the device can realize accurate positioning and adjustment of the electric cleaning device 35 and the workpiece.

[0099] The electric cleaning plate 34 is connected to the probe 36 circuit board through a gold finger socket;

[0100] The probe 36 is arranged on the probe 36 circuit board. The probe 36 is provided with multiple groups, and four groups are taken as an example in the embodiment.

[0105] In some embodiments, the crystal oscillator electric cleaning device 35 further comprises: a button box 26, an electric control cabinet 31, and a controller;

[0106] A button box 26 is arranged on the workbench 23; buttons and upper parts are provided with emergency stop switches, button switches and other components.

[0108] A controller is arranged in the electric control cabinet 31 and is electrically connected with the workpiece clamp 28, the electric cleaning device 35, the three-dimensional adjuster 32, the X-axis linear drive guide rail 21, the Z-axis linear drive guide rail 29, the adsorption assembly 27, the Y-axis linear drive guide rail 25, the button box 26. The controller comprises a PLC, a relay and the like.

[0109] A man-machine interactive screen 311 is arranged on the cabinet door of the electric control cabinet 31 and is connected with the controller.

[0110] In some embodiments, the crystal oscillator electric cleaning device 35 further comprises an alarm lamp 22.

[0111] The alarm lamp 22 is arranged on the support frame or the workbench 23 and is connected with the controller.

[0112] In some embodiments, the workpiece clamp 28 comprises a clamping groove 12, a correction sheet 11 and a linear drive mechanism.

[0113] The clamping groove 12 comprises a bottom side 121 and a first side wall 122. The bottom side 121 supports and positions the bottom of the crystal oscillator, and the first side wall 122 supports and positions the first side of the crystal oscillator. The bottom side 121 and the first side wall 122 are inner side surfaces of the groove body of the clamping groove 12. The bottom side 121 is a plane, and the first side wall 122 is a plane perpendicular to the bottom side 121.

[0114] The correction sheet 11 is in sliding cooperation with the clamping groove 12, and a front end is provided with a positioning groove 13. The positioning groove 13 positions the adjacent surface and the opposite surface of the first side. The positioning groove 13 comprises two second side walls 132 and a third side wall 131 perpendicular to each other. The two side walls are arranged at an intersection, and an angle clearance groove is arranged at the intersection. The angle clearance groove leaves a position for the top corner of the crystal oscillator. The second side wall 132 and the third side wall 131 position the adjacent surface and the opposite surface of the first side.

[0115] The linear drive mechanism is connected with the correction sheet 11 and drives the correction sheet 11 to move in a direction at an included angle S with the first side wall 122. When the positioning groove 13 approaches the first side wall 122, the positioning groove 13 cooperates with the first side wall 122 to clamp and position three surfaces of the crystal oscillator. When the positioning groove 13 is away from the first side wall 122, the clamping and positioning are released. The included angle S is in the range of 0°<S<90°.

[0116] The workpiece clamp provided by the embodiment of the present disclosure can precisely clamp and position the three surfaces of the crystal oscillator by supporting and positioning the bottom and the first side surface of the crystal oscillator through the bottom side surface 121 and the first side wall 122 of the clamping groove 12, and positioning the adjacent surface and the opposite surface of the crystal oscillator through the positioning groove 13 at the front end of the correction sheet 11. The correction sheet 11 moves in the direction of the included angle S with the first side wall 122 under the driving of the linear driving mechanism, and the positioning groove 13 is first fitted with the two side surfaces of the crystal oscillator, and after the first side surface of the crystal oscillator is tightly fitted with the first side wall 122, the correction sheet 11 stops moving, the clamping and positioning are completed, and the positioning deviation problem caused by wear of the traditional positioning device is avoided. The clamping groove 12 and the correction sheet 11 can be made of high-hardness and wear-resistant materials (such as ceramics or special alloys), which significantly improves the wear resistance of the device and prolongs the service life.

[0117] In some embodiments, the bottom side surface 121 of the clamping groove 12 is provided with a blowing and sucking hole 123 connected with a blowing and sucking device. The blowing and sucking hole 123 is in a state of air suction, and the negative pressure provided by the state of air suction causes the crystal oscillator to be adsorbed at the bottom of the clamping groove 12, greatly increases the friction between the crystal oscillator and the bottom side surface 121, and prevents the crystal oscillator from being knocked away when the correction sheet 11 collides with the crystal oscillator. The blowing and sucking device is a negative pressure air suction device.

[0118] In some embodiments, the included angle S is in the range of 30°≤S≤60°. The included angle S can be 30°, 45° or 60°.

[0119] In some embodiments, the linear driving mechanism includes a mounting plate 2, an excitation tray 1, an elastic member 14, a fixing frame 5 and an opening mechanism.

[0120] The mounting plate 2 is connected with the correction sheet 11 at the front end, and the mounting plate 2 is a rectangular plate.

[0121] The excitation tray 1 is provided with a first recess and a first sliding groove 3 at the upper portion, the first sliding groove 3 is a rectangular sliding groove, and a plurality of first recesses and first sliding grooves 3 are provided, the first recess can accommodate and install the clamping groove 12, and the first sliding groove 3 is in sliding fit with the mounting plate 2.

[0122] The elastic member 14 is connected with the excitation tray 1 at one end and connected with the mounting plate 2 at the other end, and provides a force for moving the correction sheet 11 to the first side wall 122. The elastic member 14 is a spring. The traditional clamping device cannot adapt to the size tolerance between workpieces due to the fixed structure, and can usually only clamp the largest workpiece, while the remaining workpieces cannot be effectively clamped due to the small size. The device provides clamping force through the elastic member 14, which solves this problem. Each workpiece has a corresponding individual elastic member to provide clamping force, and the elastic member has a large stroke and can adapt to the tolerance of different workpieces, especially for the scene where the workpiece shape tolerance is in the range of 0-1 mm.

[0123] In some embodiments, the elastic member corresponds to the mounting plate one-to-one, and the mounting plate corresponds to the correction sheet one-to-one.

[0124] The fixed frame 5 is arranged below the excitation tray 1; the excitation tray is arranged on the fixed frame;

[0125] The opening mechanism is arranged on the fixed frame 5 and provides a force for moving the correction sheet 11 away from the first side wall 122.

[0126] In some embodiments, the opening mechanism includes a pneumatic cylinder, a hydraulic cylinder, or an electric telescopic rod.

[0127] In some embodiments, the linear driving mechanism further includes a first sliding rail 16.

[0128] The first sliding rail 16 is arranged on the fixed frame 5 and is in sliding cooperation with the mounting plate 2 to limit the movement of the mounting plate 2 in a direction at an included angle S with the first side wall 122. The first sliding rail 16 is provided with a sliding block connected with the mounting plate 2.

[0129] In some embodiments, the opening mechanism includes a limiting plate 10, a pneumatic cylinder 6, a second sliding rail 4, a limiting groove 101, and a vertical rod 15. The pneumatic cylinder 6 drives the opening of the correction sheet 11, and the elastic member 14 is positioned back to the crystal oscillator.

[0130] The limiting plate 10 is arranged below the excitation tray 1.
