[0002] In the production of tuning fork crystals, the tuning fork crystals need to be frequency modulated to adjust the frequency of the tuning fork crystals to an appropriate range in preparation for the subsequent process of pressing and sealing to improve the yield.

[0039] The loading device 200 is used to provide carrier strips one by one;

[0040] The first laser frequency modulation device 310 and the second laser frequency modulation device 320 are arranged on both sides and are used to perform laser frequency modulation on the tuning fork crystal on the carrier bar;

[0041] The material distribution device 400 is connected between the loading device 200 and the first laser frequency modulation device 310 and the second laser frequency modulation device 320, and is used to receive the carrier strips and distribute them alternately to the first laser frequency modulation device 310 and the second laser frequency modulation device 320;

[0042] The receiving device 500 is connected to the discharge ends of the first laser frequency modulation device 310 and the second laser frequency modulation device 320, and is used to alternately receive the carrier strips after frequency modulation;

[0043] The unloading device 600 is connected to the discharge end of the receiving device 500 for conveying the carrier strips.

[0044] 1) Reference Figure 1-Figure 3 In some embodiments, the loading device 200 includes a pulley assembly 210, a first drive assembly 220, a first pushing assembly 230 and a second pushing assembly 240; the frame 100 is provided with a feed channel 110 that is docked with the dividing device 400; the pulley assembly 210 has a loading channel 250 whose end is connected to the feed channel 110, and the carrier bar is placed in the loading channel 250; the first drive assembly 220 is connected to the pulley assembly 210, and is used to drive the pulley assembly 210 to rotate; the first pushing assembly 230 is used to push the carrier bar in the loading channel 250 into the feed channel 110; the second pushing assembly 240 is used to push the carrier bar in the feed channel 110 into the dividing device 400.

[0045] When in use, multiple tuning fork crystals are loaded on the carrier bar and then transported to the loading device 200 manually or automatically. Specifically, they are placed in the loading channel 250 of the loading device 200. The loading channel 250 is composed of a pulley assembly 210 and a limit baffle on the frame 100. The first drive assembly 220 drives the pulley assembly 210 to rotate, so that the carrier bar moves close to the feed channel 110 under the drive of the pulley assembly 210, and is then pushed into the feed channel 110 by the first pushing assembly 230, and finally enters the distributing device 300 under the push of the second pushing assembly 240.

[0046] 2) Reference Figure 1-Figure 4 In some embodiments, the material distribution device 400 includes a second drive component 410, a rotating shaft 420, a first material receiving plate 430 and a second material receiving plate 440; the rotating shaft 420 is connected to the output end of the second drive component 410; the first material receiving plate 430 is connected to one side of the rotating shaft 420; the second material receiving plate 440 is connected to the other side of the rotating shaft 420; the second drive component 410 can drive the first material receiving plate 430 through the rotating shaft 420 to receive the carrier strip at the loading device 200 and distribute it to the first laser frequency modulation device 310, or drive the second material receiving plate 440 to receive the carrier strip at the loading device 200 and distribute it to the second laser frequency modulation device 320.

[0047] Furthermore, an alternating double-head laser frequency modulation machine also includes a third pushing assembly 260 for pushing the carrier strip on the dividing device 400 to the first laser frequency modulation device 310 and a fourth pushing assembly 270 for pushing the carrier strip on the dividing device 400 to the second laser frequency modulation device 320.

[0048] Specifically, in the first movement stroke, the second driving component 410 first drives the rotating shaft 420 to drive the first receiving plate 430 to rotate to be opposite to the discharge end of the loading device 200. At this time, the loading device 200 pushes the first carrier strip into the first receiving plate 430, and then drives the rotating shaft 420 to continue rotating until the first receiving plate 430 moves to be opposite to the first laser frequency modulation device 310, and then pushes the carrier strip on the first receiving plate 430 into the first laser frequency modulation device 310 through the third pushing component 260. The device 310 performs laser frequency modulation; at the same time, the second receiving plate 440 moves to be opposite to the discharge end of the loading device 200, and the loading device 200 pushes the second carrier strip into the second receiving plate 440; in the second movement stroke, the second drive assembly 410 drives the rotating shaft 420 to rotate in the opposite direction until the second receiving plate 440 is opposite to the second laser frequency modulation device 320 and the first receiving plate 430 is opposite to the discharge end of the loading device 200, and this cycle is repeated to realize the alternating distribution of the carrier strips.

[0049] Furthermore, an alternating double-head laser frequency modulation machine also includes a detection component 700 for detecting the position of the first material receiving plate 430 or the second material receiving plate 440; preferably, the detection component 700 includes a sensor 710 and an arc-shaped reflection plate 720, and the two ends of the arc-shaped reflection plate 720 are respectively connected to the first material receiving plate 430 and the second material receiving plate 440, and the signal transmitting end of the sensor 710 is opposite to the arc-shaped reflection plate 720, which can detect the position of the first material receiving plate 430 or the second material receiving plate 440, so as to facilitate the control of the movement state of the second driving component 410.

[0050] 3) It should be noted that the frequency modulator is also provided with a first clamping probe and a second clamping probe on both sides, as well as a first frequency analyzer 910 connected to the first clamping probe and a second frequency analyzer 920 connected to the second clamping probe. The first frequency analyzer 910 and the second frequency analyzer 920 perform frequency analysis on the tuning fork crystal, and control the first laser frequency modulation device 310 and the second laser frequency modulation device 320 to adjust the frequency of the tuning fork based on the analysis results. Specifically, the laser is emitted by the laser to change the thickness of the silver layer on the surface of the tuning fork, thereby changing the frequency of the tuning fork crystal to adjust the frequency to an acceptable range. This will not be described in detail here.

[0051] 4) An alternating double-head laser frequency modulation machine further includes a laser generator 810, a first beam splitter assembly 820, a second beam splitter assembly 830, a first laser head 840, and a second laser head 850. The laser generator 810 is connected to the first laser head 840 via the first beam splitter assembly 820 to form a first laser frequency modulation device 310; the laser generator 810 is connected to the second laser head 850 via the second beam splitter assembly 830 to form a second laser frequency modulation device 320.

[0052] Specifically, the laser generator 810 generates a high-energy laser beam, which enters and passes through two groups of light-splitting components respectively, and then performs laser frequency modulation on the tuning fork crystals on the two carriers through the first laser head 840 and the second laser head 850 respectively. Furthermore, since the tuning fork crystals need to be positioned, a first camera connected to the first light-splitting component 820 and a second camera connected to the second light-splitting component 830 are provided on the rack 100. The light path of the laser generator 810 and the light path of the camera are changed through the light-splitting component 820, thereby realizing the completion of video detection and laser frequency modulation through the laser head.

[0053] 5) The advantage of the present invention is that the above structure can provide carriers loaded with tuning fork crystals to two groups of laser frequency modulation devices in the form of alternating feeding, thereby achieving feeding speed matching, which not only reduces the complexity of the structure but also reduces the volume occupied by the equipment, and has very good practicality.
