[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model; that is, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The components of the embodiments of the present utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0034] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0035] The following is combined Figure 1-5 This invention describes a specific embodiment of a chip crystal oscillator detection and sorting machine, comprising:

[0036] Box 1 has a hollow interior to provide installation space for other parts;

[0037] The feeding device 2 is installed on the housing 1 and is used to store surface mount crystal oscillators and intermittently feed them to one side of the housing 1. The feeding device 2 is specifically a storage bin 21. The storage bin 21 loads and stores surface mount crystal oscillators and, at the same time, is intermittently fed downwards under the control of an electrical signal.

[0038] The conveying device 3 is installed and connected to the housing 1 for feeding and conveying the surface mount crystal oscillator. In this embodiment, the conveying device 3 is a vibratory feeder 31. The vibratory feeder 31 is a prior art technology. The vibration of the vibratory feeder 31 is used to move the track inside the surface mount crystal oscillator, so that the surface mount crystal oscillator is moved to the area to be picked up.

[0039] The gripping device 4 includes a gripping frame 42, which is movably connected to the housing 1. The gripping frame 42 has suction cups 43 at both ends. The two suction cups 43 are used simultaneously for loading the surface mount crystal oscillator before processing and unloading it after processing. Both ends of the gripping frame 42 are equipped with suction cups 43 capable of picking up surface mount crystal oscillators. The suction cups 43 are pneumatically controlled. While the gripping frame 42 picks up the surface mount crystal oscillator in the conveying device 3, the suction cup 43 at the other end picks up one of the surface mount crystal oscillators after welding. After picking up the crystal oscillator, the device moves to transfer unwelded workpieces to the welding area and welded workpieces to the unloading area for sorting. The gripping device 4 achieves fully automatic loading and unloading of surface mount crystal oscillators, and simultaneously unloads one processed surface mount crystal oscillator while loading one.

[0040] The welding device 5 includes a positioning disk 51, which is rotatably connected to the housing 1. The positioning disk 51 has several placement spaces 52. A laser welding head 54 is provided on one side of the positioning disk 51, which faces directly above the placement space 52. The gripping frame 42 picks up the surface mount crystal oscillator and loads it into the placement space 52 in the positioning disk 51. At the same time, the positioning disk 51 is rotatably connected to the housing 1. Every time the positioning disk 51 rotates a certain angle, the laser welding head 54 welds one of the surface mount crystal oscillators. The rotation of the positioning disk 51 is used to realize the welding of the surface mount crystal oscillators on the positioning disk 51 or the unloading and transfer of the welded crystal oscillators.

[0041] The storage device 6 includes a test disk 61 and a test material box 14. The test disk 61 is used to detect the resistance value of the surface mount crystal oscillators placed on it. The test material box 14 has multiple storage spaces 15. The test disk 61 is connected to the test material box 14. The soldered surface mount crystal oscillators are transferred to the top of the test disk 61 by the gripper 42. While briefly staying on the test disk 61, the test disk 61 detects the resistance value of the soldered crystal oscillators and transmits the value. The control device 7 analyzes the value and drops the soldered surface mount crystal oscillators into one of the corresponding storage spaces 15 to achieve the sorting of the soldered surface mount crystal oscillators.

[0042] Please refer to Figure 1-3 As shown in the figure, a slot is opened on one side of the housing 1, and a slide rail 12 is fixedly installed in the slot. A push plate 13 is slidably installed on the slide rail 12. The bottom of the test machine material box 14 is fixedly connected to the push plate 13. A slot is opened on one side of the housing 1, so that one side of the housing 1 is open. A slide rail 12 is installed in the slot, and a push plate 13 is slidably installed on the slide rail 12. The push plate 13 is used to support the test machine material box 14, so that the test machine material box 14 can be slidably pulled out into the housing 1 to facilitate the unloading of the surface mount crystal oscillator loaded in the test machine material box 14.

[0043] Please refer to Figures 1-3 As shown, the feeding device 2 is a storage bin 21, and the output end of the storage bin 21 extends to the conveying device 3. The storage bin 21 is equipped with a detection switch 22, which is used to control the feeding of the surface mount crystal oscillator in the feeding device 2. The detection switch 22 detects the amount of material in the vibrating plate 31 to determine whether the storage bin 21 needs to add a surface mount crystal oscillator to the vibrating plate 31.

[0044] Please refer to Figures 1-3 As shown, the conveying device 3 is a vibratory plate 31, which is a prior art device. A track is formed on the plate body of the vibratory plate 31. The track is used for the movement of the surface mount crystal oscillator on the plate body. Through the vibration of the plate body, the surface mount crystal oscillator in the plate body is transmitted and moved along a specific track.

[0045] Please refer to Figures 1-3 As shown, the gripping device 4 also includes a support frame 41, which is fixedly connected to the housing 1. The support frame 41 is equipped with a drive assembly, which is connected to the gripping frame 42 in a transmission manner. The support frame 41 is used to provide support for the gripping frame 42 and the drive assembly. The drive assembly includes at least two power modules and a limiting sliding rail for moving the gripping frame 42. The power modules can be cylinder-driven or motor-driven. The two power modules are used to drive the gripping frame 42 to move left and right and up and down, respectively. The left and right movement is used for the gripping frame 42 to pick up the chip crystal oscillator before welding and the chip crystal oscillator after welding, respectively. Before moving left and right, it moves up and down first so that the suction cup 43 avoids the positioning disk 51 and the test disk 61 to avoid collisions between them.

[0046] Please refer to Figures 2-3 As shown, the welding device 5 also includes a welding frame 53, which is fixedly installed on the housing 1. The laser welding head 54 is fixedly installed on the welding frame 53. The welding frame 53 provides support for the laser welding head 54, so that the laser welding head 54 faces one of the placement spaces 52. In some embodiments, the number of laser welding heads 54 can be several. In this embodiment, the number of laser welding heads 54 is two that are spaced apart, which improves the welding efficiency of the chip crystal oscillator while taking into account the rotation angle of the positioning disk 51 each time.

[0047] Please refer to Figures 2-5 As shown, the storage device 6 further includes:

[0048] The feeding cylinder 62 is connected to the test disk 61 at its top. Multiple feeding spaces 63 are formed inside the feeding cylinder 62, each corresponding to a storage space 15. Multiple feeding spaces 63 extend through the upper and lower ends of the feeding cylinder 62, and each feeding space 63 corresponds to a storage space 15. The multiple feeding spaces 63 are used for feeding and storing surface mount crystal oscillators of different sizes and specifications.

[0049] The unloading slide 64 is rotatably connected to the bottom of the test disk 61. One end of the unloading slide 64 is connected to the test disk 61, and the other end is connected to one of the unloading spaces 63. The unloading slide 64 is rotatably connected inside the unloading cylinder 62, and its two ends respectively support the test disk 61 and the unloading space 63. By detecting and analyzing the resistance value of the test disk 61, the rotation of the drive motor 65 is controlled by the resistance value, so that the unloading slide 64 rotates to the unloading space 63 corresponding to the detection value of the chip crystal oscillator being tested, so that the lower end of the unloading slide 64 is connected to the upper end of the unloading space 63 corresponding to the chip crystal oscillator being tested, so that the suction cup 43 contacts and grabs the chip crystal oscillator and drops it into the storage space 15, realizing the sorting and storage of chip crystal oscillators according to different specifications after soldering.

[0050] A drive motor 65 is fixedly connected inside the feeding cylinder 62. The output end of the drive motor 65 is fixedly connected to the feeding slide 64. The drive motor 65 is used to drive the rotation of the feeding slide 64.

[0051] Please refer to Figures 1-3 As shown, it also includes a control device 7, which includes:

[0052] The control screen 71 is installed on one side of the gripping device 4 and is electrically connected to the test disk 61. The control screen 71 is used to display the amount of different specifications of surface mount crystal oscillators stored in the test machine material box 14, and to display the resistance value of the surface mount crystal oscillator being tested in real time.

[0053] The measuring box 72 is installed on one side of the control screen 71 and is used to receive the values ​​measured by the test disk 61. The measuring box 72 detects the resistance of the chip crystal oscillator and analyzes the detected values ​​in order to control the rotation of the feeding slide 64.

[0054] A control button 73 is installed on the housing 1. The control button 73 includes a main switch button, a computer connection interface, and a stop knob. A fan filter assembly 11 is provided on the side adjacent to the control button 73. The fan filter assembly 11 is provided on the two side circumferences of the housing 1 for heat dissipation inside the housing 1.

[0055] Working principle of this utility model:

[0056] The surface mount crystal oscillator is loaded in the storage bin 21. The storage bin 21 intermittently feeds the surface mount crystal oscillator into the vibratory feeder 31 according to the welding speed. The surface mount crystal oscillator passes through the storage bin 21 for feeding the surface mount crystal oscillator, the conveying device 3 for transmitting the surface mount crystal oscillator, the gripping device 4 for feeding the surface mount crystal oscillator on the vibratory feeder 31 and unloading the surface mount crystal oscillator after welding on the positioning disc 51, the welding device 5 for welding the surface mount crystal oscillator on the positioning disc 51, and the storage device 6 for storing the surface mount crystal oscillator according to specifications after welding.

[0057] In the feeding device 2, the storage bin 21 is used to feed the chip crystal oscillators. At the same time, the feeding trough of the feeding device 2 is equipped with a detection switch 22. The detection switch 22 controls the opening state of the storage bin 21 feeding the vibratory feeder 31 by detecting the number of chip crystal oscillators in the vibratory feeder 31.

[0058] In the conveying device 3, the vibratory plate 31 vibrates the chip crystal oscillator on it to convey the chip crystal oscillator to the soldering and gripping area.

[0059] In the gripping device 4, suction cups 43 are provided at the left and right ends of the gripping frame 42 respectively. The left suction cup 43 corresponds to the gripping before the surface mount crystal oscillator is soldered, and the right suction cup 43 corresponds to the gripping after the surface mount crystal oscillator is unloaded. The air in the suction cup 43 is extracted by the pneumatic component to realize the gripping of the surface mount crystal oscillator.

[0060] In the welding device 5, the positioning disk 51 rotates on the housing 1, and several placement spaces 52 are formed on the positioning disk 51. The positioning disk 51 remains stationary when it is gripped by the gripping frame 42 and when it is unloaded after gripping. When the gripping frame 42 moves upward away from the positioning disk 51, the welding device 5 welds the chip crystal oscillator on the placement space 52. At the same time, after the welding is completed, it rotates a certain angle and waits for the gripping frame 42 to load material into the placement space 52 and unload one of the welded chip crystal oscillators.

[0061] In the storage device 6, the right end of the gripper 42 picks up the surface mount crystal oscillator and moves it into the test disk 61, where it stays for a few seconds. During this time, the test disk 61 detects the resistance value of the surface mount crystal oscillator located on it and transmits the data. By analyzing the data, it determines which storage space 15 the surface mount crystal oscillator belongs to, and accordingly rotates the unloading slide 64, so that the corresponding storage space 15 is connected to the lower end of the corresponding unloading cylinder 62 and the unloading slide 64. After connection, the suction cup 43 contacts and picks up the surface mount crystal oscillator, and the surface mount crystal oscillator finally slides down and is placed into the corresponding storage space 15, realizing the sorting and storage of surface mount crystal oscillators according to their different specifications after soldering.
