Description

Technical Field

[0001] The utility model relates to the technical field of quartz crystal oscillator production equipment, and particularly relates to an online crystal welding positioning fixture cleaning mechanism. Background Art

[0002] The full name of a quartz crystal oscillator is a quartz crystal resonator, which is an electronic device that generates a resonant frequency and is widely used in various electronic products. A quartz crystal oscillator mainly includes three parts: a base, a crystal, and a housing. Two pins are arranged side by side on the base. One end of the crystal is welded to the base so that the crystal is electrically connected to the two pins. The housing is sleeved outside the base so that the crystal is sealed inside the housing.

[0003] Currently, a combined carrier is used to position the crystal and the base. The combined carrier includes a base carrier and a crystal carrier. Among them, a plurality of slots for the pins on the base to be inserted are provided on the base carrier, and a guiding hole for positioning the crystal is provided on the crystal carrier. During production, the crystal carrier is first assembled to the base carrier to form a combined carrier, then the crystal is pushed into the guiding hole so that one end of the crystal abuts against the base, and then the combined carrier is transferred to a welding device to weld the crystal and the base. Finally, the crystal carrier is separated from the base carrier. There is residual crystal in the guiding hole of the separated crystal carrier. However, since the traditional method uses manual labor to remove the residual crystal in the guiding hole, the cleaning efficiency is low and the production cost of the enterprise is high.

Detailed implementation mode

[0029] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the invention and simplifying the description, rather than indicating or implying that the indicated position or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0030] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0031] As Figure 1-8 shown, the present invention discloses an online crystal 50 welding positioning fixture cleaning mechanism, which includes a machine base 10, and a conveyor trough 11, a positioning assembly 20, and a cleaning assembly 30 provided on the machine base 10.

[0032] The conveying trough 11 is used to convey the crystal carrier 40. The positioning assembly 20 and the cleaning assembly 30 are relatively arranged on both sides of the conveying trough 11. The positioning assembly 20 is used to position the crystal carrier 40 in the conveying trough 11, and the cleaning assembly 30 is used to clean the guiding holes 41 on the crystal carrier 40 to remove the residual crystals 50 in the guiding holes 41. The crystal carrier 40 after cleaning can be output by the conveying trough 11. It can be understood that the crystal carrier 40 after cleaning can also be taken away from the conveying trough 11 by a manipulator. Since there are cases where individual crystals 50 are poorly welded during welding, the poorly welded crystals 50 will remain in the guiding holes 41. To prevent the residual crystals 50 from affecting the reuse of the crystal carrier 40, it is necessary to clean the guiding holes 41.

[0033] The positioning assembly 20 has a first driving unit 21, a first movable seat 22, and a positioning member 23 provided on the first movable seat 22. The first driving unit 21 can adopt a cylinder or a linear motor. The first driving unit 21 drives the first movable seat 22 to move closer to or away from the conveying trough 11, so that the first movable seat 22 drives the positioning member 23 to extend into the conveying trough 11 to position the crystal carrier 40. By providing the positioning assembly 20 composed of the first driving unit 21, the first movable seat 22, and the positioning member 23 provided on the first movable seat 22, and using the first driving unit 21 to drive the first movable seat 22 to move closer to the conveying trough 11, the positioning member 23 can be extended into the conveying trough 11 to position the crystal carrier 40, thereby realizing the automatic positioning of the crystal carrier 40 with high positioning efficiency.

[0034] The positioning member 23 is two positioning rods 24 spaced on the first movable seat 22. A pin hole 241 is provided at the end of the positioning rod 24. The pin hole 241 can be inserted into the positioning pin 42 on the crystal carrier 40 to limit the movement of the crystal carrier 40 along the conveying direction of the conveying trough 11. Specifically, the central axis of the positioning rod 24 extends horizontally, and a first avoidance groove 13 for the telescopic movement of the positioning pin 42 is communicated with one side of the conveying trough 11. By providing the positioning member 23 composed of two positioning rods 24 and providing the pin hole 241 at the end of the positioning rod 24, when the positioning rod 24 moves closer to the crystal carrier 40, the positioning pin 42 on the crystal carrier 40 is inserted into the pin hole 241 to limit the movement of the crystal carrier 40 along the conveying direction of the conveying trough 11, realizing the positioning of the crystal carrier 40 along the conveying direction of the conveying trough 11.

[0035] One side of the conveying trough 11 away from the positioning rod 24 has a positioning surface 14. The positioning rod 24 pushes against the crystal carrier 40 to make the crystal carrier 40 abut against the positioning surface 14, so as to limit the movement of the crystal carrier 40 in a direction perpendicular to the conveying direction of the conveying trough 11. By providing the positioning surface 14, the positioning rod 24 pushes the crystal carrier 40 to move, and when the positioning surface 14 abuts against the crystal carrier 40, the movement of the crystal carrier 40 in a direction perpendicular to the conveying direction of the conveying trough 11 can be limited, realizing the positioning of the crystal carrier 40 in a direction perpendicular to the conveying direction of the conveying trough 11.

[0036] The positioning assembly 20 further has a first mounting seat 25. The first mounting seat 25 is screwed to one side of the machine base 10. The first driving unit 21 is arranged on the first mounting seat 25, and the first movable seat 22 is slidably connected to the first mounting seat 25. By providing the first mounting seat 25, the first movable seat 22 and the first driving unit 21 can be assembled to the first mounting seat 25 first, and then the first mounting seat 25 can be installed on the machine base 10, making the installation and disassembly of the positioning assembly 20 more convenient.

[0037] The cleaning assembly 30 has a second driving unit 31, a second movable seat 32, and push pieces 33 arranged side by side on the second movable seat 32. The second driving unit 31 can be a cylinder or a linear motor. The second driving unit 31 drives the second movable seat 32 to move closer to or away from the conveying trough 11, so that the second movable seat 32 drives the push pieces 33 to extend into the guiding holes 41 to push the remaining crystals 50 outwards. Specifically, the other side of the conveying trough 11 is communicated with a second avoidance groove 15 for the push pieces 33 to telescopically move. By providing the cleaning assembly 30 composed of the second driving unit 31, the second movable seat 32, and the push pieces 33 arranged side by side on the second movable seat 32, the second driving unit 31 is used to drive the second movable seat 32 to move closer to the conveying trough 11, so that the push pieces 33 extend into the guiding holes 41 to push out the remaining crystals 50 in the guiding holes 41, thereby realizing the automatic cleaning of the crystal carrier 40 with high cleaning efficiency.

[0038] The pusher 33 extends downwardly and obliquely in a direction approaching the conveying groove 11. The moving direction of the second movable seat 32 is parallel to the extending direction of the pusher 33. The pusher 33 can be elastically bent and deformed. When the pusher 33 is obliquely inserted into the guiding hole 41, the end of the pusher 33 close to the conveying groove 11 is elastically bent upwardly so that the lower surface of the pusher 33 makes sliding contact with the lower surface in the guiding hole 41. Specifically, the pusher 33 is a thin metal sheet, enabling the pusher 33 to have the ability to be elastically bent upwardly or downwardly. By providing the elastically bendable pusher 33, when the pusher 33 is obliquely inserted into the guiding hole 41, the end of the pusher 33 close to the conveying groove 11 is elastically bent upwardly, making the lower surface of the pusher 33 make sliding contact with the lower surface in the guiding hole 41, so that the pusher 33 extends into the guiding hole 41 in a shoveling manner to push the remaining crystal 50 outwards, and the cleaning effect is better.

[0039] The included angle β between the pusher 33 and the horizontal plane is 1 degree - 5 degrees, and preferably the included angle β is 3 degrees.

[0040] The pusher 33 is slidably connected to the second movable seat 32. A buffer spring (not shown) corresponding to the pusher 33 is provided in the second movable seat 32. The buffer spring always makes the pusher 33 tend to move in a direction approaching the conveying groove 11. One end of the buffer spring abuts against the cleaning head, and the other end of the buffer spring abuts against the pusher 33. By providing the buffer spring, the pusher 33 has a buffering effect, preventing the pusher 33 from being deformed and damaged due to hard pushing.

[0041] The cleaning assembly 30 further has a second mounting seat 34. The second mounting seat 34 is screwed to the other side of the machine base 10. The second driving unit 31 is provided on the second mounting seat 34. The second movable seat 32 is slidably connected to the second mounting seat 34.

[0042] On one side of the positioning assembly 20 away from the incoming material direction of the crystal carrier 40, a first material blocking assembly 16 for restricting the movement of the crystal carrier 40 in the conveying groove 11 is provided. The first material blocking assembly 16 has a first material blocking rod 161 and a third driving unit 162. The third driving unit 162 can drive the first material blocking rod 161 to extend into or withdraw from the conveying groove 11. Specifically, the first material blocking assembly 16 is provided above the conveying groove 11, and the third driving unit 162 can drive the first material blocking rod 161 to extend into or withdraw from the conveying groove 11 in the vertical direction.

[0043] On one side of the positioning assembly 20 close to the incoming material direction, a second material blocking assembly 18 for restricting the movement of the crystal carrier 40 in the conveying groove 11 is provided. The second material blocking assembly 18 has a second material blocking rod 181 and a fourth driving unit 182.

[0044] One side of the first material blocking rod 161 close to the incoming material direction of the crystal carrier 40 is provided with a sensor 17. The sensor 17 is located directly above the conveying groove 11. The sensor 17 can adopt an optical fiber sensor 17. When the sensor 17 detects the crystal carrier 40, the third driving unit 162 drives the first material blocking rod 161 to extend into the conveying groove 11 to limit the movement of the crystal carrier 40.

[0045] A conveyor belt 12 for driving the crystal carrier 40 to move is provided in the conveying groove 11. At least one waste material discharging port 19 is provided between one side of the conveyor belt 12 away from the cleaning assembly 30 and the inner wall of the conveying groove 11. Exemplarily, the number of the waste material discharging ports 19 is two or three. The multiple waste material discharging ports 19 are distributed along the conveying direction of the conveying groove 11. During operation, the pusher 33 on the cleaning assembly 30 pushes the residual crystal 50 in the guiding hole 41 out and drops it into the waste material discharging port 19, and flows out from the waste material discharging port 19. By providing the waste material discharging port 19, the residual crystal 50 in the guiding hole 41 is pushed out by the cleaning assembly 30 and flows out from the waste material discharging port 19 in time, avoiding accumulation in the conveying groove 11.

[0046] The working principle of the present utility model:

[0047] The conveyor belt 12 drives the crystal carrier 40 to be cleaned in the conveying groove 11 to move;

[0048] When the sensor 17 detects the frontmost crystal carrier 40, the fourth driving unit 182 drives the second material blocking rod 181 to extend into the conveying groove 11 to limit the movement of the subsequent crystal carrier 40;

[0049] The third driving unit 162 drives the first material blocking rod 161 to extend into the conveying groove 11 to limit the movement of the crystal carrier 40. The first driving unit 21 drives the first movable seat 22 to move close to the conveying groove 11. The first movable seat 22 drives the positioning member 23 to extend into the conveying groove 11. The two positioning rods 24 push the crystal carrier 40 to move in a direction perpendicular to the conveying direction of the conveying groove 11, so that the side wall of the crystal carrier 40 abuts against the positioning surface 14. At the same time, the two positioning pins 42 on the crystal carrier 40 are correspondingly inserted into the pin holes 241 on the positioning rods 24 to complete the positioning of the crystal carrier 40;

[0050] The second driving unit 31 drives the second movable seat 32 to move close to the conveying groove 11. The second movable seat 32 drives the pusher 33 to be obliquely inserted into the guiding hole 41. One end of the pusher 33 close to the conveying groove 11 is elastically bent upward, so that the pusher 33 pushes the residual crystal 50 in the guiding hole 41 out in a shoveling manner, and the pushed-out crystal 50 drops into the waste material discharging port 19.

[0051] In summary, the present utility model realizes an automatic cleaning process of carrier transportation, carrier positioning, and carrier cleaning with high efficiency and reduced production costs of enterprises by arranging a conveying groove 11, a positioning assembly 20, and a cleaning assembly 30 on a machine base 10.
