Description

Technical Field

[0002] The quartz crystal resonator converts electrical energy into mechanical vibration through the piezoelectric effect, and resonates at a specific frequency to generate a stable oscillation signal. The stability and accuracy of its performance are crucial to the operation of the electronic circuit system. During the operation, it will produce certain resistance and capacitance effects. After the main production of the resonator components is completed, in order to ensure that the electrode pins are normally connected after welding and avoid quality problems caused by poor connection or disconnection, it is necessary to detect the resistance value of the pins to ensure that they can be used normally to avoid quality problems;

[0003] Due to the large number, manual inspection can only be carried out on a sampling basis, and the yield rate cannot be strictly and effectively controlled, and the efficiency is low. Automatic inspection of the resonator during inspection can significantly improve the efficiency, but according to the different needs of specific applications, the size and specifications of the quartz crystal resonator are also different. The size and packaging of the quartz crystal resonator are varied to meet the needs of various electronic products. The currently used detection instruments need to replace the corresponding detection ports when testing resonators of different specifications, which delays the detection process.

DETAILED DESCRIPTION

[0041] The following are specific embodiments of the present invention, and the technical solutions of the present invention are further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0042] like Figure 1-15As shown, the present invention provides an automatic detection device for computer quartz crystal resonators for electronic engineering research, comprising two belt conveyors 1 arranged correspondingly in front and back, and a quartz crystal resonator placed on the upper side of the belt conveyor 1 on the front side in the same placement state and equidistantly. The belt conveyor is used in conjunction with a feeding device, so that the quartz crystal resonator can be placed on the upper side of the belt conveyor 1 on the front side in the same placement state and equidistantly. A detection device is arranged on the right side between the two belt conveyors 1, and a grabbing device that reciprocates back and forth is installed on the lower side of the detection device. When the device is in use, the grabbing device and the detection device are alternately coordinated with each other to perform automatic detection on the quartz crystal resonator, thereby increasing the detection accuracy and improving the detection efficiency.

[0043] The detection device includes a shell 4, a lifting box 6 slidably connected to the inside of the shell 4 and capable of moving up and down, and a detection platform 3 located at the lower side of the lifting box 6. A support plate 5 is fixedly connected to the right end of the shell 4. The lower end of the support plate 5 is bent ninety degrees toward the lower side of the detection platform 3. The bent portion is used as a base of the detection device. The detection platform 3 is fixedly connected to the support plate 5. The support plate 5 is used to support the detection device. The detection platform 3 serves as a detection platform for the quartz crystal resonator, which is convenient for detecting the quartz crystal resonator. Detection heads with adjustable spacing are respectively arranged on the left and right sides of the lower end of the lifting box 6. The heights of the two detection heads are respectively staggered. An adjustment structure is installed inside the lifting box 6 to adjust the heights of the two detection heads during detection. When detecting the quartz crystal resonator, the lifting box 6 can be controlled to move downward, and the electrode pins of the quartz crystal resonator can be detected by contacting the detection head, and the two heights are set. Different detection heads can make the two detection heads contact the electrode pins one after another, reduce the influence of external interference on the detection, ensure the stability of the detection environment, and ensure the transmission of the detection signal, avoid signal distortion or attenuation, and improve the accuracy of the detection. The set adjustment structure can quickly drive the other detection head to detect the electrode pin after one detection head contacts the electrode pin, thereby ensuring the detection efficiency; the left and right sides of the surface of the detection platform 3 are respectively slidably connected with a fixed plate 39 that can move inward synchronously. The fixed plate 39 is used to detect and fix the quartz crystal resonator during detection. When the lifting box 6 moves downward, a structure in which the two fixed plates 39 move inward synchronously can be formed, so that after the detection head moves downward and contacts the electrode pin of the quartz crystal resonator, the fixed plate 39 can synchronously clamp and fix the quartz crystal resonator, thereby ensuring the stability of the quartz crystal resonator during detection and the accuracy of the detection data;

[0044] The rear sides of the two fixed plates 39 are respectively provided with swing plates 37 opposite to each other. The surface of the swing plate 37 is hinged to the inner wall of the shell 4. The upper ends of the two fixed plates 39 are respectively slidably matched with the corresponding surfaces of the swing plates 37. The upper ends of the fixed plates 39 are respectively fixedly connected with matching pins 41. The lower sides of the surfaces of the swing plates are respectively provided with oblique grooves 40. The matching pins 41 are slidably connected with the oblique grooves 40. A conical push plate 32 is provided on the inner sides of the upper ends of the two swing plates 37. When the conical plate rotates, the upper ends of the two swing plates 37 can be pushed to swing outward. Under the action of the swing plate 37 being hinged to the inner wall of the shell 4, the lower side of the swing plate 37 swings inward and drives the two fixed plates 39 to move inward under the sliding cooperation of the oblique grooves 40 and the matching pins 41. When the lifting box 6 is lifted or lowered, a structure in which the conical plate reciprocates can be formed; Figure 8-Figure 9 As shown, the width of the conical push plate 32 decreases from top to bottom. When the conical push plate 32 moves downward, the distance that the lower end of the swing plate 37 swings inward can be increased. When the two detection heads move inward, a structure for the conical push plate 32 to move downward can be formed, so that the distance that the two fixed plates 39 move inward can be adjusted synchronously with the change of the spacing between the two detection heads. When in use, in order to improve the applicability of the detection equipment and facilitate the detection of quartz crystal resonators of different sizes, the spacing between the detection heads can be adjusted according to the spacing between the electrode pins of the quartz crystal resonator. When the spacing between the two detection heads is adjusted, the distance that the two fixed plates 39 can move inward can also be adjusted, ensuring that after adjusting the two detection heads, the fixed plate 39 can still stably clamp and fix the new quartz crystal resonator to be detected, thereby fully improving the detection range.

[0045] like Figure 4-Figure 7As shown, the adjustment structure includes a transition gear 7 rotatably connected to the inner wall of the lifting box 6, and meshing racks 8 are respectively meshed on both sides of the transition gear 7. The meshing racks 8 are respectively slidably connected to the lower end of the lifting box 6, and the lower ends of the meshing racks 8 are respectively fixedly connected to mounting guide rails 9. When the lifting box 6 moves downward, when one of the detection heads contacts the electrode pin, the detection head will encounter resistance and drive the transition gear 7 to rotate through the meshing of the meshing rack 8 and the transition gear 7, and then drive the detection head on the other side to move downward quickly through the meshing of the transition gear 7 and the meshing rack 8 on the other side to detect with the other electrode pin, thereby ensuring the detection efficiency; the detection head includes a sliding block 11 slidably connected to the bottom of the mounting guide rail 9, and the sliding block The lower ends of the detection rods 11 are respectively fixedly connected with buffer cylinders 10, and the lower side of the buffer cylinder 10 is axially slidably connected with a detection rod 13, and the bottom of the detection rod 13 is fixedly connected with an electrode sheet 14, and the two electrode sheets 14 are divided into positive and negative electrodes, which are respectively electrically connected to the detector. After the electrode sheets 14 contact the electrode pins, the resistance value is detected by the detector to determine whether the quartz crystal resonator is damaged, and the upper end of the detection rod 13 is fixedly connected with a buffer spring 12, the buffer spring 12 is located inside the buffer cylinder 10 and the upper end of the buffer spring 12 is fixedly connected to the inner wall of the buffer cylinder 10, and the buffer spring 12 is used to provide a buffering effect to prevent the electrode sheet 14 and the electrode pin from being damaged due to excessive impact after the electrode sheet 14 contacts the electrode pins;

[0046] The support spring 85 is used to support the two detection cylinders by their own elastic force, and improve the stability of the two detection cylinders. Under the elastic force of the support spring 85, the support plate 5 can remain stable, so that the transition gear 7 remains stable, and can remain motionless when the detection head is not affected by external forces, thereby ensuring the stability of the two detection heads when not in use.

[0047] like Figure 6As shown, the inner ends of the two sliding blocks 11 are respectively fixedly connected with a connecting rod 15, and the bottom of the lifting box 6 is respectively slidably connected with a mounting slide block 16 that can move left and right. The connecting rod 15 is respectively vertically slidably connected with the mounting slide block 16. Under the action of the sliding connection between the connecting rod 15 and the mounting slide block 16, it does not affect the vertical movement of the two detection heads relative to each other to realize the detection operation. The surfaces of the two mounting slide blocks 16 are respectively fixedly connected with a reversing rack 18, and a reversing gear 17 is meshed between the two reversing racks 18. A mounting sleeve 21 is fixedly connected to the middle part of the reversing gear 17, and a mounting rod 20 is rotatably connected to the middle part of the mounting sleeve 21. The upper end of the mounting rod 20 is fixedly connected to the bottom of the lifting box 6. When the two detection heads move, the two mounting slide blocks 16 can be driven to move synchronously relative to each other through the connecting rod 15, thereby driving the two reversing racks 18 to move, and the two detection heads can be synchronously moved relative to each other under the meshing of the reversing gear 17 and the reversing gear 17, so that the positions of the two detection heads can be adjusted simultaneously, which is convenient for operation.

[0048] like Figure 8-Figure 9 As shown, a spline groove is provided downwardly at the upper end of the conical push plate 32, and a second spline shaft 36 is splinedly connected to the inner side of the spline groove. Under the action of the spline connection between the second spline shaft 36 and the spline groove, when the conical push plate 32 moves downward, it does not affect the second spline shaft 36 driving the conical push plate 32 to rotate. The lower end of the conical push plate 32 is rotatably connected to a connecting frame 33, and a slide plate 35 is vertically slidably connected to the surface of the connecting frame 33. The slide plate 35 is fixedly connected to the inner wall of the shell 4. Under the sliding connection between the connecting frame 33 and the slide plate 35, the stability of the key-shaped push plate when it moves up and down can be ensured; a horizontally arranged The front end of the connecting frame 33 is provided with a lower pressing plate 30, one end of the lower pressing plate 30 is rotatably connected to the inner wall of the shell 4, and the other end of the lower pressing plate 30 is fixedly connected to a connecting pin 31, and the connecting pin 31 is slidably connected to the matching sliding groove 34. When the lower pressing plate 30 rotates downward, the sliding cooperation between the connecting pin 31 and the matching sliding groove 34 can push the conical push plate 32 to move downward. After the conical push plate 32 moves downward, when it rotates, due to the larger width of the upper side of the conical push plate 32, the greater the distance the lower side of the swing plate 37 is pushed to swing inward, the greater the distance the fixed plate 39 is pushed to move inward.

[0049] Furthermore, in order to synchronize the adjustment of the distance between the detection heads and the adjustment of the moving distance of the fixed plate 39, a second transmission bevel gear 29 is coaxially fixedly connected to one end of the lower pressure plate 30 that is rotatably connected to the outer shell 4, a first transmission bevel gear 28 is meshed on the upper side of the second transmission bevel gear 29, a first spline shaft 27 is fixedly connected to the middle part of the first transmission bevel gear 28, the first spline shaft 27 is rotatably connected to the inner wall of the outer shell 4, a first spline cylinder 26 is splined on the surface of the first spline shaft 27, the first spline cylinder 26 is rotatably connected to the lifting box 6, a second transmission pulley 25 is fixedly connected to the upper surface of the first spline cylinder 26, a first transmission pulley 19 is fixedly connected to the upper surface of the mounting sleeve 21, a first transmission belt is sleeved between the first transmission pulley 19 and the second transmission pulley 25, and when the two detection heads move inward, The reversing gear 17 is driven to rotate by the reversing rack 18, and the mounting sleeve 21 rotates synchronously. When the mounting sleeve 21 rotates, the first spline cylinder 26 can be driven to rotate under the transmission of the first transmission pulley 19, the second transmission pulley 25 and the first transmission belt. When the first spline cylinder 26 rotates, the first transmission bevel gear 28 is driven to rotate under the action of the spline connection with the first spline shaft 27, and the lower pressure plate 30 is driven to rotate under the meshing and transmission of the first transmission bevel gear 28 and the second transmission bevel gear 29. When the lower pressure plate 30 rotates, the conical push plate 32 can be driven to move downward under the sliding cooperation of the connecting pin shaft 31 and the matching slide groove 34, and the first spline cylinder 26 moves downward synchronously when the lifting box 6 moves downward, but the transmission effect on the first spline shaft 27 is not affected under the action of the spline connection between the first spline cylinder 26 and the first spline shaft 27.

[0050] Furthermore, in order to improve the stability of the two detection heads when not in use and avoid displacement of the two detection heads when not in use, thereby affecting the detection accuracy, a sliding plate is fixedly connected to the lower end of the mounting rod 20, and a limit tooth block 22 is arranged on the lower side of the sliding plate. The upper end of the limit tooth block 22 is meshed with the reversing gear 17, and a limited motion groove is radially provided at the lower end of the sliding plate. A limit slider is fixedly connected to the surface of the limit tooth block 22, and the limit slider is slidably connected to the limit groove. A limit spring 23 is fixedly connected to the front end of the limit slider, and the other end of the limit spring 23 is fixedly connected to the inner wall of the connecting groove 24. Under the push of the limit spring 23, the limit tooth block 22 can brake the two detection heads by meshing with the reversing gear 17 to avoid the two detection heads from moving at will. Since the meshing surfaces of the limit tooth block 22 and the reversing gear 17 are both inclined surfaces, when used to move the two detection heads, the elastic force of the limit spring 23 can be overcome to drive the reversing gear 17 to rotate, thereby causing the two detection heads to move.

[0051] like Figure 10-11As shown, a control motor 44 is provided at the rear side of the lifting box 6, and the control motor 44 is fixedly connected to the housing 4. An incomplete bevel gear 56 and an active dial wheel 50 are fixedly connected to the output end of the lower side of the control motor 44. The incomplete bevel gear 56 and the active dial wheel 50 are coaxially arranged. A fixed tooth plate 42 is fixedly connected to the rear end of the lifting box 6. A driving gear 43 is meshed with one side of the fixed tooth plate 42. The driving gear 43 is rotatably connected to the inner wall of the housing 4. A matching bevel gear 55 is coaxially fixedly connected to the rear side of the driving gear 43. When the incomplete bevel gear 56 rotates, it can mesh with the matching bevel gear 55 to drive The driving gear 43 rotates, and when the driving gear 43 rotates, it can drive the lifting box 6 to move downward by meshing with the fixed tooth plate 42. The left and right ends of the lifting box 6 are respectively fixedly connected with lifting sliders, and the lifting sliders are respectively slidably connected to the inner walls of the shell 4. The lower ends of the lifting sliders are respectively fixedly connected with lifting springs, and the other ends of the lifting springs are respectively fixedly connected to the inner walls of the shell 4. The lifting springs are used to support the lifting box 6. When the lifting box 6 moves downward, the lifting springs will be squeezed. When the incomplete bevel gear 56 is disengaged from the matching bevel gear 55, the lifting box 6 can be pushed by the lifting springs to move upward to end the detection;

[0052] The front side of the active dial wheel 50 is meshed with a first groove wheel 51, and the first groove wheel 51 is rotatably connected to the inner wall of the shell 4. Under the meshing of the active dial wheel 50 and the first groove wheel 51, the first groove wheel 51 can be driven to rotate intermittently. The lower side of the first groove wheel 51 is coaxially fixedly connected with a gear ring 48, the inner side of the gear ring 48 is meshed with a connecting gear 49, and the lower side of the connecting gear 49 is coaxially fixedly connected with a rotating disk 45, the rotating disk 45 is rotatably connected to the inner wall of the shell 4, and the lower side of the surface of the rotating disk 45 is hinged at a non-center position A hinged rod 47 is connected, and a connecting plate 46 is fixedly connected to the upper end of the second spline shaft 36. The hinged rod 47 is hinged to the other end of the connecting plate 46. When the first groove wheel 51 rotates, the gear ring 48 is synchronously driven to rotate, and then the rotating disk 45 is driven to rotate through the meshing of the gear ring 48 and the connecting gear 49. When the rotating disk 45 rotates, the connecting plate 46 is pulled to swing toward the active dial wheel 50 through the transmission of the hinged rod 47, and then the conical push plate 32 is driven to rotate through the second spline shaft 36, which drives the two fixed plates 3 9 synchronously moves inward; further, when the rotating disk 45 rotates 180 degrees each time, the conical push plate 32 can be driven to rotate 90 degrees by the hinge rod 47. When the rotating disk 45 rotates 180 degrees again, the conical push plate 32 can be pushed to reset by the hinge rod 47, forming an effect that the conical push plate 32 reciprocates once after the lifting box 6 moves up and down once, and the active dial 50 and the first groove wheel 51 provided in the device form a groove wheel mechanism as a 90-degree groove wheel mechanism. The first groove wheel 51 rotates 90 degrees intermittently each time. In order to make up for the difference in the rotation angle during transmission, the number of teeth of the ring gear 48 is twice the number of teeth of the connecting gear 49. When the ring gear 48 rotates 90 degrees, it can drive the connecting gear 49 to rotate 180 degrees. Then, after the connecting gear 49 rotates, it can drive the rotating disk 45 to rotate 180 degrees, ensuring that after the active dial 50 rotates, not only the lifting box 6 can be driven to move up and down once, but also the conical push plate 32 can be driven to reciprocate once, thereby realizing the simultaneous fixing and detection of the quartz crystal resonator.

[0053] like Figure 12-Figure 15As shown, the grabbing device includes a frame-shaped box 68 and two groups of grabbing frames located on the front and rear sides of the frame-shaped box 68. The grabbing frame includes a horizontally arranged cross plate 87 and an adjusting block 69 slidably connected to the front and rear sides of the lower end of the cross plate 87. The lower end of the adjusting block 69 is vertically slidably connected to a clamping block 70. When the two adjusting blocks 69 move inward synchronously, the two clamping blocks 70 can be driven to move inward synchronously. The quartz crystal resonator is detected and fixed by the two clamping blocks 70. The upper ends of the two clamping blocks 70 are respectively fixedly connected to sliding rods 71, and the upper ends of the sliding rods 71 ​​are respectively slidably connected to the adjusting blocks 69. Then, the length of the sliding rod 71 is used as the distance that the clamping block 70 can move upward, providing a buffer for the clamping block 70 when clamping the quartz crystal resonator; the upper ends of the two horizontal plates 87 are fixedly connected to a stabilizing plate, and the front and rear sides of the surface of the stabilizing plate are respectively fixedly connected with support pins 66, and the surface of the frame-shaped box 68 is provided with a track groove 67, and the support pin 66 is slidably connected with the track groove 67. A push structure that can swing back and forth is installed on the left side of the frame-shaped box 68. When the push structure swings back and forth, the support pin 66 and the track groove 67 are slidably matched to drive the grab frame to move back and forth along the track groove 67;

[0054] A synchronous rack 72 is fixedly connected between the two corresponding adjustment blocks 69, and a synchronous gear 73 is meshed between the synchronous racks 72. The synchronous gear 73 is rotatably connected to the corresponding cross plate 87. Under the action of the synchronous gear 73, the synchronous racks 72 on the upper and lower sides can move synchronously, and the corresponding synchronous racks 72 on the front and rear sides of the lower side are fixedly connected to each other, so that the synchronous racks 72 on the front and rear sides can move synchronously, thereby driving the synchronous gears 73 on the front and rear sides to rotate synchronously. A driven plate 79 is fixedly connected to the right end of the synchronous gear 73 coaxially, and a connecting block 80 is slidably connected to the upper side of the driven plate 79 along the length direction. A tension spring 81 is fixedly connected to the surface of the linkage block, and the other end of the tension spring 81 is fixedly connected to the surface of the driven plate 79; a limit plate 77 is provided on the upper side of the driven plate 79, and the limit plate 77 is fixed to the cross plate 87 The locking cam 76 is engaged with the locking cam 78 by the spring 81, and the locking cam 76 engages with the locking cam 78 to lock the locking cam 78.

[0055] When the driven plate 79 swings, it can drive the synchronous gear 73 to rotate. When the synchronous gear 73 rotates, it drives the adjusting block 69 to move synchronously inwards by meshing with the synchronous racks 72 on both sides, and then uses the clamping block 70 to clamp and fix the quartz crystal resonator. When the grab frame moves to the front side to the upper side of the front belt conveyor 1, it moves downward so that the two clamping blocks 70 are located at the front and rear sides of the quartz crystal resonator. At this time, the grab frame continues to move downward and the driven plate 79 is synchronously swung to the rear side under the obstruction of the first gear rod 75, and drives the synchronous gear 73 to rotate. The meshing of the synchronous gear 73 and the synchronous rack 72 drives the clamping block 70 to move inwards to clamp and fix the quartz crystal resonator, and when the driven plate 79 swings, the sliding cooperation between the limit groove 78 and the linkage pin 82 will drive the connecting block 80 to move upward and stretch the tension spring 81, and then when the driven plate 79 swings to the rear side, the linkage pin 82 is pulled by the tension spring 81 to move to The other end of the limit groove 78 provides resistance for the swing of the driven plate 79 through the tension of the tension spring 81, thereby improving the stability of the driven plate 79 and the firmness of the clamping block 70 clamping the quartz crystal resonator; when the grabbing frame on the front side moves to the rear side to the top of the detection table 3 and then moves downward again, the grabbing frame on the rear side returns to the top of the belt conveyor on the rear side, and then when the grabbing frame moves downward, the two driven plates 79 are synchronously swung to the rear side under the blockage of the second gear rod 76, thereby driving the synchronous gear 73 to rotate to move the two clamping blocks 70 outward, so that the quartz crystal resonator stays on the detection table 3 for detection, and the buffer distance between the clamping block 70 and the adjusting block 69 makes up for the distance that the grabbing frame continues to move downward after the clamping block 70 contacts the belt conveyor 1, so that the two clamping blocks 70 can be located at the front and rear sides of the quartz crystal resonator and then clamp and fix the quartz crystal resonator, thereby ensuring the stability of the quartz crystal resonator clamping;

[0056] When the two grabbing frames move forward and backward synchronously, they can correspond to the belt conveyors and the testing table 3 on the front and rear sides respectively. When the grabbing frames move toward the front side, the grabbing frame on the front side grabs the quartz crystal resonator on the upper side of the belt conveyor on the front side, and the grabbing frame on the rear side grabs the quartz crystal resonator on the upper side of the testing table 3 that has been tested. Then, when the grabbing frames move toward the rear side synchronously, the grabbing frame on the rear side places the tested quartz crystal resonator on the belt conveyor frame on the rear side for transportation, and the grabbing frame on the front side places the quartz crystal resonator to be tested on the testing table 3 for testing. This achieves that when the two grabbing frames move forward and backward synchronously, the grabbing frame on the front side can continuously transfer the quartz crystal resonator to be tested on the upper side of the belt conveyor on the front side to the testing table 3 for testing, and the grabbing frame on the rear side can continuously transfer the quartz crystal resonator tested on the testing table 3 to the belt conveyor on the rear side, thereby achieving the effect of automatic grabbing and testing.

[0057] like Fig.13As shown, the pushing structure includes two pushing plates 65 which are rotatably connected to the left end of the frame box 68 and can swing back and forth synchronously. A pushing groove is provided on the surface of the pushing plate 65. The two ends of the track groove 67 are bent downward by ninety degrees respectively. The support pins 66 pass through the track grooves 67 respectively and the outer ends of the support pins 66 are slidably matched with the corresponding pushing grooves respectively. When the pushing plate 65 swings forward, it can drive the grabbing frame to move upward along the track groove 67 first, then swing forward, and then move downward to grab the quartz crystal resonator. When the pushing plate 65 swings backward, it can drive the grabbing frame to move upward along the track groove 67 first, then move backward, and then move downward. Release the quartz crystal resonator, and one end of the two push plates 65 rotatably connected to the frame box 68 is respectively coaxially fixedly connected with a linkage pulley 64, and a second transmission belt is sleeved between the two linkage pulleys 64. Under the transmission of the linkage pulley 64 and the second transmission belt, the two push plates 65 can swing synchronously, and the left end of one of the linkage pulleys 64 is coaxially fixedly connected with a reciprocating gear 60, and the upper side of the reciprocating gear 60 is meshed with a reciprocating rack 59 that can move back and forth, and the reciprocating rack 59 is slidably connected to the surface of the frame box 68. When the reciprocating rack 59 moves back and forth, it can drive the two push plates 65 to swing back and forth synchronously through the meshing with the reciprocating gear 60.

[0058] Figure 11-Figure 12 As shown, the upper end of the reciprocating rack 59 is fixedly connected to a vertical plate, a strip groove 63 is vertically opened on the surface of the vertical plate, a rotating rod 61 is arranged on the left side of the vertical plate, a second connecting pulley 58 is fixedly connected to the lower side of the surface of the rotating rod 61, and a push pin 62 is fixedly connected to the upper side of the surface of the rotating rod 61, and the push pin 62 is slidably matched with the strip groove 63. When the rotating rod 61 rotates around the axis of the second connecting pulley 58 as the center, the reciprocating rack 59 can be driven to reciprocate back and forth through the sliding cooperation between the push pin 62 and the strip groove 63;

[0059] A second paddle wheel is meshed on one side of the active paddle wheel 50 away from the first groove wheel 51, and the second paddle wheel is rotatably connected to the inner wall of the housing 4. A first output bevel gear 53 is coaxially fixedly connected to the lower side of the second paddle wheel, and a second output bevel gear 54 is meshed on the lower side of the first output bevel gear 53, and the second output bevel gear 54 is rotatably connected to the inner wall of the housing 4. A first connecting pulley 57 is coaxially fixedly connected to the left side of the second output bevel gear 54, and a third transmission belt is sleeved between the first connecting pulley 57 and the second connecting pulley 58. When the active paddle wheel 50 rotates, the first groove wheel 51 and the second groove wheel 52 can be driven to rotate alternately. When the second groove wheel 52 rotates, the first output bevel gear 53 can be driven to rotate. When the first output bevel gear 53 rotates ninety degrees with the second groove wheel 52, the second output bevel gear 54 can be driven to rotate three hundred and sixty degrees, and then the first output bevel gear 53 rotates ninety degrees along with the second groove wheel 52. The first connecting pulley 57, the second connecting pulley 58 and the third transmission belt drive the rotating rod 61 to rotate 360 ​​degrees. When the rotating rod 61 rotates 360 degrees, the reciprocating rack 59 can be driven to move back and forth once by pushing the sliding cooperation between the pin shaft 62 and the strip groove 63, and then the pushing plate 65 is driven to swing back and forth once under the meshing of the reciprocating rack 59 and the reciprocating gear 60, so that the grabbing frame can grab the quartz crystal resonator. Moreover, since the active dial wheel 50 can drive the first groove wheel 51 and the second groove wheel 52 to rotate alternately when rotating, the grabbing frame grabs the quartz crystal resonator and the detection equipment detects the quartz crystal resonator alternately, thereby automatically detecting the quartz crystal resonator and automatically removing the quartz crystal resonator after detection, which is convenient for continued detection, and can fully improve the detection accuracy, expand the scope of application, and improve the detection efficiency.
