[0002] The full name of quartz crystal oscillator is quartz crystal resonator, which is an electronic device that generates resonant frequency and is widely used in various electronic products. Quartz crystal oscillator mainly consists of three parts: base, crystal and shell. There are two pins 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 shell is covered outside the base to seal the crystal inside the shell.

[0003] At present, a combined carrier is used to position the crystal and the base. The combined carrier includes a base carrier and a crystal carrier. The base carrier is provided with a plurality of slots for inserting the pins on the base, and the crystal carrier is provided with a guide hole for positioning the crystal. During production, the crystal carrier is assembled onto the base carrier to form a combined carrier, and then the crystal is pushed into the guide hole so that one end of the crystal abuts against the base, and finally the crystal and the base are welded. The traditional method uses a pushing mechanism to horizontally push the crystal in a lying position. Since the crystal in a lying position has the problem of detaching from the base in the combined carrier, it is necessary to set a pushing mechanism that can vertically push the crystal in an upright position.

DETAILED DESCRIPTION

[0025] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the position or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0026] 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 a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0027] like Figure 1-4 As shown, the utility model discloses a crystal pushing mechanism 80, including a pushing driving device 81, at least one pushing seat 82 and a plurality of pushing members 83 arranged on the pushing seat 82 at intervals. Exemplarily, the number of the pushing seats 82 is two, and the two pushing seats 82 are distributed along the X-axis direction.

[0028] The push drive device 81 can drive the push seat 82 to move up and down, so that the push seat 82 drives the push member 83 to push the upright crystal 92 on the assembly carrier 90 vertically downward, and make the lower end of the pushed crystal 92 abut against the upper end of the base 91.

[0029] The pusher 83 is connected to the pusher seat 82 for sliding up and down. The pusher seat 82 is provided with a buffer spring 84 corresponding to the pusher 83. The buffer spring 84 makes the pusher 83 always have a tendency to move downward. The pusher seat 82 is provided with a detection device 85 for detecting whether the pusher 83 pushes the crystal 92 in place. By arranging the buffer spring 84 corresponding to the pusher 83 on the pusher seat 82 and the detection device 85, the buffer spring 84 makes the pusher 83 always have a tendency to move downward. There is a tendency to move downward, and the pushing seat 82 drives the pushing piece 83 to move downward so that the pushing piece 83 pushes the crystal 92 downward. When the pushing piece 83 pushes the crystal 92 normally, the pushing piece 83 and the pushing seat 82 are relatively stationary. When the pushing piece 83 pushes the crystal 92 abnormally (for example, the crystal 92 is stuck in the combined carrier 90 and cannot continue to move downward), the pushing piece 83 will move upward relative to the pushing seat 82 and produce displacement. The detection device 85 detects the upward displacement of the pushing piece 83 to determine that the crystal 92 is not pushed into place.

[0030] The detection device 85 comprises a first sensor 851 and a second sensor 852 cooperating with the first sensor 851. Exemplarily, both the first sensor 851 and the second sensor 852 are optical fiber sensors. A detection area 853 is formed between the first sensor 851 and the second sensor 852, into which the upper end of the pusher 83 can extend upward. The pusher 83 is arranged directly below the detection area 853. During operation, the pusher seat 82 drives the pusher 83 to move downward. If the crystal 92 is stuck on the combined carrier 90, the pusher 83 will be unable to push the crystal 92 downward. When the pusher seat 82 continues to move downward, the crystal 92 acts in the opposite direction on the pusher 83 to make the upper end of the pusher 83 extend upward into the detection area 853. At this time, if the detection device 85 detects the upper end of the pusher 83, it indicates that the pusher 83 is not in place to push the crystal 92; if the upper end of the pusher 83 does not extend into the detection area 853, it indicates that the pusher 83 is in place to push the crystal 92.

[0031] The pushing piece 83 is provided with an upwardly extending mounting rod 831 and a downwardly extending pushing rod 832. The mounting rod 831 is located in the pushing seat 82. The upper end of the pushing seat 82 is provided with a first avoidance hole 821 for the mounting rod 831 to pass upward and extend into the detection area 853. The buffer spring 84 is sleeved on the outer side of the mounting rod 831. The upper end of the buffer spring 84 abuts against the pushing seat 82. The lower end of the buffer spring 84 abuts against the pushing piece 83. The lower end of the pushing rod 832 passes through the pushing seat 82 and extends downward. When working, the pushing rod 832 is inserted into the guide hole 901 on the combined carrier 90 to push the crystal 92 in an upright position downward.

[0032] The crystal pushing mechanism 80 also includes at least one guide seat 86. Exemplarily, there are two guide seats 86, and the two guide seats 86 correspond to the pushing seats 82 one by one. The driving end of the pushing drive device 81 is connected to a guide column 811, and the guide column 811 is connected to the pushing seat 82. The guide column 811 can drive the pushing seat 82 to move up and down. The pushing seat 82 is slidably installed on the guide seat 86 by the guide column 811. The guide seat 86 is provided with a guide groove 861 corresponding to the pushing member 83 one by one. The pushing member 83 slides up and down and penetrates the corresponding guide groove 861. Specifically, the pushing member The rod 832 slides up and down and passes through the corresponding guide groove 861. The guide seat 86 is provided with a guide sleeve 862 corresponding to the guide column 811. The guide column 811 is slidably sleeved in the guide sleeve 862. The upper end of the guide column 811 is connected with a lifting seat 812, and the lifting seat 812 is connected to the driving end of the pushing drive device 81. By setting the guide seat 86, the pushing seat 82 is slidably installed on the guide seat 86 by using the guide rod, and the pushing piece 83 slides up and down and passes through the guide groove 861 on the guide seat 86, so that the pushing seat 82 and the pushing piece 83 remain stable when moving up and down, thereby improving the pushing effect of the crystal 92.

[0033] The guide seat 86 is slidably installed on the frame 100 up and down, and a limit piece 88 is connected between the guide seat 86 and the frame 100 to limit the downward movement of the guide seat 86. A return spring 87 and a clamping assembly 89 are provided between the guide seat 86 and the pushing seat 82. The upper end of the return spring 87 abuts against the pushing seat 82, and the lower end of the return spring 87 abuts against the guide seat 86. The pushing seat 82 can drive the guide seat 86 to move downward through the return spring 87, and the guide seat 86 drives the guide seat 86 to move upward through the clamping assembly 89; by setting the guide seat 86 and the frame 100 to be slidably connected up and down, a limit piece 88 is connected between the guide seat 86 and the frame 100, and the guide seat 86 and the pushing seat 82 are connected. A return spring 87 and a clamping assembly 89 are provided between the pushing seat 82, and the limit piece 88 limits the maximum downward travel of the guide seat 86. The return spring 87 enables the pushing seat 82 to drive the guide seat 86 to move downward, and the clamping assembly 89 enables the pushing seat 82 to drive the guide seat 86 to move upward. The downward movement of the guide seat 86 can lower the height of the guide groove 861, which can reach the upper end surface of the combined carrier 90 at the lowest. Therefore, when the pushing piece 83 passes through the guide groove 861 and is inserted downward into the combined carrier 90, the guide groove 861 keeps guiding the pushing piece 83, thereby enabling the pushing piece 83 to push the crystal 92 downward more smoothly and stably. In addition, the return spring 87 also has a buffering effect to prevent the pushing piece 83 from damaging the crystal 92.

[0034] The limiting member 88 has a limiting column 881 and a limiting block 882, the lower end of the limiting column 881 is connected to the guide seat 86, the limiting column 881 can move up and down with the guide seat 86, the upper end of the limiting column 881 passes through the second avoidance hole 101 on the frame 100 and extends upward to connect the limiting block 882, the limiting block 882 abuts against the upper edge of the second avoidance hole 101 to limit the downward movement of the guide seat 86, specifically, the limiting column 881 is a limiting bolt, the lower end of the limiting bolt is threadedly connected to the guide seat 86, and the limiting block 882 is a bolt head provided on the limiting bolt.

[0035] The clamping assembly 89 is composed of a clamping block 891 and a clamping slot 892. The clamping block 891 is arranged on the pushing seat 82, and the clamping slot 892 is arranged on the guide seat 86. The clamping block 891 is arranged in the clamping slot 892 for vertical movement. The clamping block 891 abuts against the inner top wall of the clamping slot 892 so that the pushing seat 82 drives the guide seat 86 to move upward. The clamping slot 892 passes through both sides of the guide seat 86 along the Y-axis direction to form a hollow groove.

[0036] The guide column 811 is inserted into the connecting hole 8911 on the clamping block 891, and the clamping block 891 is provided with a locking piece 8912 which extends into the connecting hole 8911 to lock the guide column 811. Specifically, the locking piece 8912 is a locking screw, and one end of the locking screw extends into the connecting hole 8911 and abuts against the outer wall of the guide column 811 to lock the guide column 811 with the pushing seat 82.

[0037] The guide seat 86 is provided with a limit pin 863 , the return spring 87 is sleeved on the outside of the limit pin 863 , and the pusher seat 82 is provided with a third avoidance hole (not shown) for the limit pin 863 to pass upward.

[0038] The lower end of the guide seat 86 is laterally protruded to form a stopper 864, and the stopper 864 is located directly below the material pushing seat 82. The stopper 864 limits the downward movement of the material pushing seat 82 relative to the guide seat 86, and the guide groove 861 passes through the stopper 864 downward.

[0039] The working principle of the utility model is as follows: the pushing drive device 81 drives the pushing seat 82 to move downward for the first time, the pushing seat 82 drives the pushing piece 83 to move downward, and the pushing seat 82 pushes the reset spring 87 so that the reset spring 87 pushes the guide seat 86 to move downward. When the limit member 88 abuts against the frame 100, the guide seat 86 stops moving downward, and the pushing drive device 81 drives the pushing seat 82 to move downward for the second time, the pushing seat 82 drives the pushing piece 83 to move downward, so that the pushing rod 832 on the pushing piece 83 passes through the guide slot 861 and downwardly inserts into the combined carrier 90 to push the crystal 92 in an upright posture, so that the lower end of the crystal 92 abuts against the base 91. When the lower surface of the pushing seat 82 abuts against the stop block 864, the pushing seat 82 stops moving downward. When the pushing drive device 81 drives the pushing seat 82 to move upward and reset, the pushing seat 82 first moves up a distance and then drives the guide seat 86 to move upward.

[0040] In summary, the utility model sets a crystal pushing mechanism 80 which is composed of a pushing drive device 81, a pushing seat 82 and a plurality of pushing pieces 83 which are spaced apart on the pushing seat 82. When working, the pushing drive device 81 drives the pushing seat 82 to move up and down, so that the pushing seat 82 drives the pushing piece 83 to push the crystal 92 in an upright position on the combination carrier 90 vertically downward, and makes the lower end of the pushed crystal 92 abut against the upper end of the base 91, so that the crystal pushing mechanism 80 can push the crystal 92 in an upright position on the combination carrier 90 vertically downward.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Therefore, any modification, equivalent replacement, improvement, etc. made to the above embodiment based on the technical practice of the present invention still falls within the scope of the technical solution of the present invention.
