DETAILED DESCRIPTION

[0028] The following is combined with Figure 1-Figure 4 This application is described in further detail.

[0029] A crystal oscillator testing and packaging integrated machine, refer to Figure 1As shown, it includes a frame 1 and a workbench 2 arranged on the frame 1. A material transfer tray 3 is rotatably mounted on the workbench 2. A rotating shaft 4 is fixed to the center of the material transfer tray 3. The rotating shaft 4 is mounted on the workbench 2 through a bearing so that the material transfer tray 3 rotates on the workbench 2. The material transfer tray 3 is made of acrylic board. The lower surface of the material transfer tray 3 is in contact with the upper surface of the workbench 2. The material transfer tray 3 and the workbench 2 are both circular.

[0030] The frame 1 is provided with a feeding station, a test direction component 5, a crystal oscillator direction rotation component 6, at least one electrical testing component 7, at least one sorting and collecting bin 8, a discharging station and an unqualified rejection bin 9 in sequence along the rotation direction of the material transfer tray 3. A driving motor 10 for driving the material transfer tray 3 to rotate in steps is provided on the workbench 2. The driving motor 10 is connected to the rotating shaft 4 of the material transfer tray 3. It is worth noting that the feeding station, the test direction component 5, the crystal oscillator direction rotation component 6, the electrical testing component 7, the sorting and collecting bin 8 and the discharging station are arranged at equal intervals, and the step rotation distance of the driving motor 10 each time is the same as the spacing between the above-mentioned feeding station, the test direction component 5, the crystal oscillator direction rotation component 6, the electrical testing component 7, the sorting and collecting bin 8 and the discharging station.

[0031] The edge of the material transfer tray 3 is provided with a number of material loading slots 11 at equal intervals along the circumferential direction. The material loading slots 11 are used to accommodate crystal oscillators. When the driving motor 10 drives the material transfer tray 3 to rotate in steps, the material loading slots 11 of the material transfer tray 3 can stop at the feeding station, the test direction component 5, the crystal oscillator direction rotating component 6, the electrical test component 7, the sorting and collecting bin 8 and the discharging station one by one.

[0032] The frame 1 is provided with a feed vibrating plate 12, the output port of which is connected to a feed track 13, which faces the feed station. The frame 1 is provided with a transfer assembly 14 for transferring the crystal oscillator from the feed track 13 to the loading slot 11 of the transfer plate 3. The feed vibrating plate 12 is used to place the crystal oscillator. After the crystal oscillator passes through the feed vibrating plate 12, it enters the feed track 13 in the same direction.

[0033] Reference Figure 1 and Figure 2a As shown, the transfer assembly 14 includes a transfer frame 141 provided on the frame 1, and a transfer cylinder 142 provided on the transfer frame 141. A support frame 143 is mounted on the output rod of the transfer cylinder 142, and a transfer vacuum cylinder 144 is provided on the support frame 143. The transfer cylinder 142 moves the transfer vacuum cylinder 144 to above the feed track 13. The downward movement of the transfer vacuum cylinder 144 can adsorb the crystal oscillator in the feed track 13, and then the transfer cylinder 142 moves the crystal oscillator to above the material trough 11 of the transfer tray 3 and places the crystal oscillator in the material trough 11.

[0034] The transfer plate 3 rotates to move the crystal oscillator from the feeding station to the test direction component 5. The test direction component 5 includes two test electrodes and a test push cylinder that pushes the two test electrodes to move. Since there are two pins at each end of the crystal oscillator, the two pins at one end of the crystal oscillator are signal pins, and the two pins at the other end of the crystal oscillator are ground pins. The two test electrodes are used to contact the two pins at the end of the crystal oscillator to short-circuit the two pins at the end of the crystal oscillator, so as to determine whether the two pins of the crystal oscillator are signal pins or ground pins through the size of the resistance.

[0035] After passing through the test direction component 5, the material transfer tray 3 rotates the crystal oscillator into the crystal oscillator direction rotating component 6, and the two signal pins of the crystal oscillator are always facing outward through the crystal oscillator direction rotating component 6.

[0036] Reference Figure 1 and Figure 2b As shown, the crystal oscillator direction rotation assembly 6 includes a mounting bracket 61 and a lifting cylinder 62 disposed on the mounting bracket 61. A double-headed motor 63 is mounted on the output rod of the lifting cylinder 62. The motor shaft of the double-headed motor 63 is arranged in the vertical direction. The motor shaft of the double-headed motor 63 is penetrated by an air vent. An air suction pipe 2064 is mounted on the upper end of the motor shaft of the double-headed motor 63, and a material suction nozzle 65 is mounted on the lower end of the motor shaft of the double-headed motor 63. When the crystal oscillator direction rotation assembly 6 needs to rotate the crystal oscillator in the material trough 11, the lifting cylinder 62 drives the double-headed motor 63 to move downward, and the material suction nozzle 65 of the double-headed motor 63 absorbs the crystal oscillator. After the double-headed motor 63 drives the crystal oscillator to rotate 180 degrees, the crystal oscillator is placed back into the material trough 11.

[0037] The transfer tray 3 rotates to transfer the crystal oscillator from the crystal oscillator direction rotating component 6 to the electrical testing component 7 .

[0038] The electrical test component 7 is provided on at least one side. In one embodiment, three electrical test components 7 are provided, namely an insulation test component, an impedance test component and a resonant frequency test component. The structure of the electrical test component 7 is the same as that of the test direction component 5. The electrical test component 7 includes two test metal sheets and a test cylinder for pushing the two test metal sheets. The test cylinder pushes the two test metal sheets to contact the two signal pins on the crystal oscillator, and the test instrument connected through the test metal sheets completes the insulation test, impedance test and resonant frequency test of the crystal oscillator.

[0039] After the crystal oscillator completes the electrical test, the transfer plate 3 rotates to transfer the crystal oscillator from the electrical test component 7 to the sorting and collecting bin 8. In this embodiment, there are two sorting and collecting bins 8, and the two sorting and collecting bins 8 are arranged at intervals. Each sorting and collecting bin 8 is used to sort and collect crystal oscillators with corresponding electrical performance, but the crystal oscillator is still a qualified product. The opening of the sorting and collecting bin 8 faces the material trough 11, so that the crystal oscillator in the material trough 11 can be blown or moved into the sorting and collecting bin 8.

[0040] Reference Figure 1 and Figure 4 As shown, after the crystal oscillator passes through the sorting and collecting bin 8, the transfer tray 3 rotates to transfer the crystal oscillator from the sorting and collecting bin 8 to the discharge station. A discharge conveyor belt 15 is provided on the frame 1, and a packaging material belt 16 is provided on the discharge conveyor belt 15. A discharge assembly 17 for transferring the crystal oscillator from the material trough 11 to the packaging material belt 16 is provided on one side of the discharge station of the frame 1. The discharge assembly 17 includes a discharge bracket 171 and a discharge cylinder 172 provided on the discharge bracket 171. A fixing bracket 173 is installed on the output rod of the discharge cylinder 172, and a discharge vacuum cylinder 174 is provided on the fixing bracket 173.

[0041] The discharge vacuum cylinder 174 can adsorb the crystal oscillator in the trough 11, and after being moved by the discharge cylinder 172, it is placed in the packaging material belt 16 for subsequent packaging and packaging. Among them, the discharge component 17 only moves the crystal oscillator in the trough 11 that has passed the electrical test.

[0042] The unqualified crystal oscillators will rotate through the transfer plate 3 and enter the unqualified rejection bin 9, which is set toward the side of the material storage trough 11, and then the unqualified crystal oscillators will be removed from the material storage trough 11 and enter the unqualified rejection bin 9.

[0043] In this application, reference is made to Figure 1 and Figure 3 As shown, the workbench 2 is provided with a ventilation channel 18 at the test direction component 5, the electrical test component 7, the sorting and collecting bin 8, and the unqualified rejection bin 9, and a ventilation groove 19 is provided in the material transfer tray 3 along its radial direction, one end of the ventilation groove 19 is communicated with the material storage trough 11, and the other end of the ventilation groove 19 is communicated with the ventilation channel 18.

[0044] An air suction pipe 2064 is connected to the ventilation channel 18 of the test direction component 5 and the electrical test component 7, and an air suction solenoid valve 21 is installed on the air suction pipe 2064. An air blowing pipe 22 is connected to the ventilation channel 18 of the sorting and collecting bin 8 and the unqualified rejection bin 9, and an air blowing solenoid valve 23 is installed on the air blowing pipe 22.

[0045] After the suction solenoid valve 21 is triggered to open, the suction pipe 2064 sucks air, and the material trough 11 can have a certain suction force, thereby facilitating the test direction component 5 and the electrical test component 7 to test the crystal oscillator in the material trough 11. After the air blowing solenoid valve 23 is triggered to open, the air blowing pipe 22 blows air, thereby blowing the crystal oscillator out of the material trough 11 and into the sorting and collection bin 8 or the unqualified rejection bin 9.

[0046] It is worth noting that the frame 1 is provided with a discharge infrared detector 24 between the sorting and collecting bin 8 and the discharge station. The discharge infrared detector 24 is used to detect whether there is a crystal oscillator in the feeding trough 11. When it is detected that there is a crystal oscillator in the feeding trough 11, and the crystal oscillator is a qualified product and has not entered the sorting and collecting bin 8, the discharge infrared detector 24 will control the operation of the discharge component 17, and transfer the crystal oscillator from the feeding trough 11 to the packaging material belt 16 through the discharge component 17.

[0047] The frame 1 is provided with a rejection infrared detector 25 at the position of the unqualified rejection bin 9. The rejection infrared detector 25 is used to detect whether there is a crystal oscillator in the material trough 11. When the rejection infrared detector 25 detects that there is a crystal oscillator in the material trough 11 corresponding to the unqualified rejection bin 9, the rejection infrared detector 25 will control the unqualified rejection bin 9 to have a crystal oscillator, thereby blowing the crystal oscillator from the material trough 11 into the unqualified rejection bin 9.

[0048] In this application, the crystal oscillator is placed in the feeding slot 11 of the transfer tray 3 in the feeding station, and the transfer piece passes through the test direction component 5, the crystal oscillator direction rotation component 6, the electrical test component 7, the sorting and collection bin 8, the discharging station and the unqualified rejection bin 9 in turn through step rotation, thereby completing the electrical performance test, sorting, discharging and rejection of unqualified products of the crystal oscillator, with a high degree of automation, thereby effectively improving the test efficiency.

[0049] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
