[0002] The full name of a quartz crystal oscillator is a quartz crystal resonator, which is an electronic device that generates a resonant frequency and is widely used in various electronic products. A quartz crystal oscillator mainly includes three parts: a base, a crystal, and a housing. Two pins are 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 housing is sleeved outside the base so that the crystal is sealed inside the housing.

[0003] Currently, a combined carrier is used to position the crystal and the base. The combined carrier includes a base carrier and a crystal carrier. Among them, a plurality of slots for inserting the pins on the base are provided on the base carrier, and a guiding hole for positioning the crystal is provided on the crystal carrier. During production, the crystal carrier is first assembled to the base carrier to form a combined carrier, then the crystal is pushed into the guiding hole so that one end of the crystal abuts against the base, and then the combined carrier is transferred to welding equipment to weld the crystal and the base. Finally, the crystal carrier is separated from the base carrier. However, the traditional production method uses manual operation. Workers manually load the combined carrier onto the welding equipment and manually separate the crystal carrier from the base carrier after welding.

[0035] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the indicated position or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0036] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" 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 directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0037] AsFigure 1-14 As shown in the figure, the present utility model discloses a crystal welding machine, which includes a frame 10, and a carrier loading mechanism 20, a welding conveying mechanism 30, and a carrier separating and handling mechanism 40 that are sequentially arranged on the frame 10.

[0038] The carrier loading mechanism 20 can convey the combined carrier 80 to the welding conveying mechanism 30. The welding conveying mechanism 30 can weld the crystal 90 and the base 91 on the combined carrier 80, and convey the combined carrier 80 with the crystal 90 and the base 91 welded to the carrier separating and handling mechanism 40. Above the welding conveying mechanism 30, there is an air extraction hood 37, and the air extraction hood 37 is used to extract the waste gas and dust generated during the welding process. The carrier separating and handling mechanism 40 can pull out the crystal carrier 81 on the combined carrier 80 upward, so that the crystal carrier 81 on the combined carrier 80 is separated from the base carrier 82. After separation, the crystal carrier 81 carries the crystal 90 and the base 91 that have been welded.

[0039] A carrier return mechanism 50 and a carrier handling and cleaning mechanism 60 are also arranged on the frame 10. The carrier separating and handling mechanism 40 can transfer the separated crystal carrier 81 to the carrier return mechanism 50. The carrier handling and cleaning mechanism 60 is arranged on one side of the carrier loading mechanism 20. The carrier handling and cleaning mechanism 60 can move the crystal carrier 81 out of the carrier return mechanism 50 and clean the guide holes 811 on the crystal carrier 81 to remove the residual crystal 90 in the guide holes 811. Since there are individual crystals 90 with poor welding during welding, the poorly welded crystals 90 will remain in the guide holes 811. To prevent the residual crystals 90 from affecting the reuse of the crystal carrier 81, it is necessary to clean the guide holes 811.

[0040] The vehicle loading mechanism 20 has a first conveying groove 21 for conveying the combined vehicle 80. The welding conveying mechanism 30 has a second conveying groove 31 and a welding assembly 32. The input end of the second conveying groove 31 is communicated with the output end of the first conveying groove 21. The welding assembly 32 can weld the crystal 90 and the base 91 on the combined vehicle 80 in the second conveying groove 31. The vehicle separation and handling mechanism 40 has a third conveying groove 41 and a separation and handling manipulator 42. The input end of the third conveying groove 41 is communicated with the output end of the second conveying groove 31. The separation and handling manipulator 42 can pull out the crystal carrier 81 on the combined vehicle 80 in the third conveying groove 41 upward and transfer it to the vehicle return mechanism 50. Among them, conveyor belts 411 for driving the movement of the combined vehicle 80 are provided in the first conveying groove 21, the second conveying groove 31, and the third conveying groove 41. After the crystal carrier 81 is separated from the base carrier 82, the base carrier 82 is output from the third conveying groove 41 to the next working station. In addition, a material transfer mechanism can also be provided outside the first conveying groove 21, the second conveying groove 31, and the third conveying groove 41, and the material transfer mechanism drives the corresponding combined vehicle 80 in the first conveying groove 21, the second conveying groove 31, and the third conveying groove 41 to move.

[0041] The welding assembly 32 includes a first heating assembly 321 and a second heating assembly 322 that are oppositely arranged on both sides of the second conveying groove 31. The first heating assembly 321 and the second heating assembly 322 are each provided with a plurality of hot air heating tubes 323 that are spaced apart along the conveying direction of the second conveying groove 31. Each of the hot air heating tubes 323 can work independently. One end of the hot air heating tube 323 close to the second conveying groove 31 is provided with an air outlet 324, and the air outlet 324 is arranged in a flat shape. The end of the hot air heating tube 323 far from the second conveying groove 31 is connected to an air source device. Exemplarily, there are twelve hot air heating tubes 323 on both the first heating assembly 321 and the second heating assembly 322. The air outlet 324 blows hot air onto the combined carrier 80 in the second conveying groove 31, so that the crystal 90 on the combined carrier 80 is welded to the base 91. Among them, before the carrier loading mechanism 20 conveys the combined carrier 80, solder paste has been pre-attached to the connection between the crystal 90 and the base 91 on the combined carrier 80. When the first heating assembly 321 and the second heating assembly 322 blow hot air onto the combined carrier 80 in the second conveying groove 31, the solder paste is heated and melted to weld the base 91 and the crystal 90. It can be understood that the welding assembly 32 can also adopt a soldering gun, and the soldering gun welds the crystal 90 and the base 91 through solder wire. When using the soldering gun method, it is not necessary to pre-attach the solder paste to the connection between the crystal 90 and the base 91; by arranging the hot air heating tubes 323 that are spaced apart along the conveying direction of the second conveying groove 31, and each hot air heating tube 323 can work independently, each hot air heating tube 323 heats its own heating area, and the temperature of the air output by the hot air heating tube 323 can be adjusted as needed to achieve the best welding effect between the crystal 90 and the base 91.

[0042] The hot air heating tube 323 is rotatably adjusted and installed on the mounting shaft 34 on the frame 10 through a rotary adjustment seat 33 to adjust the angle of the air outlet 324 of the hot air heating tube 323. The central axis of the mounting shaft 34 is parallel to the extending direction of the second conveying groove 31. A support seat 35 is provided on the frame 10, and the mounting shaft 34 can be adjusted up and down and installed on the support seat 35 to adjust the height of the hot air heating tube 323.

[0043] An insulation cover 36 is provided above the second conveying groove 31. The insulation cover 36 is arranged in an arc shape. The air outlet 324 of the hot air heating tube 323 extends into the insulation cover 36, and the insulation cover 36 is a high-temperature resistant asbestos cover.

[0044] The separation and handling manipulator 42 has a first driving device 421 and at least one first material taking module 422. The first driving device 421 drives the first material taking module 422 to move closer to or away from the third conveying trough 41, so that the first material taking module 422 pulls out the crystal carrier 81 on the combined carrier 80 in the third conveying trough 41 upward.

[0045] There are two first material taking modules 422. The two first material taking modules 422 are arranged side by side in the Y-axis direction at the driving end of the first driving device 421. The carrier separation and handling mechanism 40 further has a transfer platform 43. The first driving device 421 drives the two first material taking modules 422 to move synchronously. After one of the first material taking modules 422 pulls out the crystal carrier 81 in the third conveying trough 41, it transfers it to the transfer platform 43, and the other first material taking module 422 transfers the crystal carrier 81 on the transfer platform 43 to the carrier return mechanism 50; by setting two material taking modules and a transfer platform 43, one material taking module pulls out the crystal carrier 81 in the first conveying trough 21 and transfers it to the transfer platform 43, and the other material taking module transfers the crystal carrier 81 on the transfer platform 43 to the carrier return mechanism 50. Compared with a single material taking module, the use of a double material taking module can reduce the movement stroke and has higher efficiency.

[0046] The first material taking module 422 is a clamping module. The clamping module has clamping jaws (not shown) that can clamp the crystal carrier 81 and a clamping driving unit (not shown) that drives the clamping jaws to open and close. The clamping driving unit can use a cylinder. The clamping module has two clamping jaws, so that the clamping module can simultaneously grab two crystal carriers 81; by using a clamping module with double clamping jaws, the clamping module can simultaneously grab two crystal carriers 81, and the efficiency is higher. It can be understood that the first material taking module 422 can also be a suction module, and the suction module has a suction cup that can suck the crystal carrier 81.

[0047] The first driving device 421 has a first Y-axis driving device 4211 and a first Z-axis driving device 4212. The first Y-axis driving device 4211 is arranged on the frame 10. The driving end of the first Y-axis driving device 4211 is connected to the first Z-axis driving device 4212. The driving end of the first Z-axis driving device 4212 is connected to the first material taking module 422. It can be understood that the first Y-axis driving device 4211 and the first Z-axis driving device 4212 can adopt one of the driving methods of cylinder, linear motor, screw + motor, and gear rack, and the positions of the first Y-axis driving device 4211 and the first Z-axis driving device 4212 can be interchanged.

[0048] Below the third conveying trough 41, there is a jacking assembly 44 for jacking up the combined carrier 80. On one side of the third conveying trough 41, there is a positioning assembly 45 for positioning the base 91 on the combined carrier 80. When the jacking assembly 44 jacks up the combined carrier 80, the positioning assembly 45 abuts downward against the base 91 on the combined carrier 80. By providing the jacking assembly 44 and the positioning assembly 45, the jacking assembly 44 jacks up the combined carrier 80 upward so that the positioning assembly 45 abuts downward against the base 91 on the combined carrier 80. When the separation handling manipulator 42 pulls out the crystal carrier 81 upward, it can prevent the base 91 from moving upward with the crystal carrier 81 and detaching from the base carrier 82.

[0049] The jacking assembly 44 has a jacking seat 441 and a jacking drive unit 442. The jacking drive unit 442 can adopt a cylinder. The jacking drive unit 442 can drive the jacking seat 441 to move up and down, so that the jacking seat 441 jacks up the third conveying trough 41 and the combined carrier 80.

[0050] The positioning assembly 45 has a positioning seat 451 and a first positioning drive unit 452. The first positioning drive unit 452 can adopt a cylinder. The positioning seat 451 is arranged above the third conveying trough 41. The first positioning drive unit 452 can drive the positioning seat 451 to move closer to or away from the third conveying trough 41, so that the side edge of the positioning seat 451 close to the third conveying trough 41 extends above the base 91.

[0051] On the side of the positioning assembly 45 away from the incoming material direction of the combined carrier 80, there is a material blocking assembly 46. The material blocking assembly 46 has a material blocking rod 461 and a material blocking drive unit 462. The material blocking drive unit 462 can adopt a cylinder. The material blocking drive unit 462 drives the material blocking rod 461 to move telescopically, so that the material blocking rod 461 restricts the movement of the combined carrier 80 / base carrier 82.

[0052] The carrier handling and cleaning mechanism 60 has a cleaning platform 61 and a handling and cleaning manipulator 62. On the handling and cleaning manipulator 62, there are a second drive device 621, a second material taking module 622, and a cleaning module 623. The second drive device 621 can drive the second material taking module 622 to reciprocate between the carrier return mechanism 50 and the cleaning platform 61, so that the second material taking module 622 transfers the crystal carrier 81 from the carrier return mechanism 50 to the cleaning platform 61. The cleaning module 623 is used to clean the guiding holes 811 on the crystal carrier 81. The carrier return mechanism 50 has a fourth conveying trough 51 for conveying the crystal carrier 81. The structure and principle of the second material taking module 622 are the same as those of the first material taking module 422, so they will not be elaborated here.

[0053] The second material taking module 622 and the cleaning module 623 are arranged side by side in the Y-axis direction at the driving end of the second driving device 621. The second driving device 621 can drive the second material taking module 622 and the cleaning module 623 to move synchronously. When the second material taking module 622 moves directly above the carrier return mechanism 50, the cleaning module 623 moves directly above the cleaning platform 61.

[0054] The second driving device 621 has a second Y-axis driving device 6211 and a second Z-axis driving device 6212. The second Y-axis driving device 6211 is arranged on the frame 10. The driving end of the second Y-axis driving device 6211 is connected to the second Z-axis driving device 6212. The driving end of the second Z-axis driving device 6212 is connected to the second material taking module 622 and the cleaning module 623. It can be understood that the positions of the second Y-axis driving device 6211 and the second Z-axis driving device 6212 can be interchanged.

[0055] The cleaning module 623 has a lifting driving unit 6231, a cleaning head 6232, and a plurality of insertion rods 6233 arranged side by side in the X-axis direction on the cleaning head 6232. The driving end of the second driving device 621 is connected to the lifting driving unit 6231. The lifting driving unit 6231 drives the cleaning head 6232 to move up and down, so that the cleaning head 6232 drives the insertion rods 6233 to insert downward into the corresponding guide holes 811 to push the remaining crystals 90 outwards. Specifically, the upper end of the insertion rod 6233 slides up and down in the cleaning head 6232. A buffer spring (not shown) corresponding to the insertion rod 6233 is arranged in the cleaning head 6232. The buffer spring makes the insertion rod 6233 always have a tendency to move downward. The upper end of the buffer spring abuts against the cleaning head 6232, and the lower end of the buffer spring abuts against the insertion rod 6233. The lifting driving unit 6231 is installed at the driving end of the second Z-axis driving device 6212. The cleaning head 6232 is connected to the driving end of the lifting driving unit 6231. The lifting driving unit 6231 can adopt a cylinder.

[0056] A receiving groove 611 for placing the crystal carrier 81 is arranged on the cleaning platform 61. A carrier discharging mechanism 70 is arranged at one end of the receiving groove 611 in the X-axis direction. A pushing driving unit 63 is arranged at the other end of the receiving groove 611 in the X-axis direction. The pushing driving unit is used to push the crystal carrier 81 that has been cleaned in the receiving groove 611 to the carrier discharging mechanism 70.

[0057] The driving end of the material pushing driving unit 63 is connected with a material pushing block 631. The material pushing driving unit 63 drives the material pushing block 631 to move in the accommodating groove 611, so as to push the crystal carrier 81 that has been cleaned in the accommodating groove 611 out to the carrier discharging mechanism 70. Specifically, the carrier discharging mechanism 70 has a fifth conveying groove 71 communicated with the accommodating groove 611, and the material pushing driving unit 63 can adopt a cylinder.

[0058] On one side of the accommodating groove 611, there is a second positioning driving unit 64. The driving end of the second positioning driving unit 64 is connected with at least two positioning rods 641 that can extend into or withdraw from the accommodating groove 611. The two positioning rods 641 respectively abut against both ends of the crystal carrier 81 to limit the movement of the crystal carrier 81 in the accommodating groove 611. Specifically, the second positioning driving unit 64 can adopt a cylinder.

[0059] At the bottom inside the accommodating groove 611, there is a waste material discharging port (not shown), and a waste material collecting box 65 is arranged below the waste material discharging port.

[0060] The working principle of the present utility model:

[0061] The first conveying groove 21 conveys the combined carrier 80 to the second conveying groove 31, and the second conveying groove 31 conveys the combined carrier 80 to the third conveying groove 41. When the combined carrier 80 moves in the second conveying groove 31, the hot air heating tubes 323 on both sides of the second conveying groove 31 simultaneously blow hot air towards the crystal 90 and the base 91 on the combined carrier 80, so that the solder paste at the connection between the crystal 90 and the base 91 is heated and melted to weld the base 91 and the crystal 90.

[0062] The third conveying groove 41 conveys the combined carrier 80 after the crystal 90 and the base 91 are welded to the material blocking assembly 46. The material blocking driving unit 462 drives the material blocking rod 461 to extend into the third conveying groove 41 to limit the movement of the combined carrier 80. The first positioning driving unit 452 drives the positioning seat 451 to move close to the third conveying groove 41, so that the edge of the side of the positioning seat 451 close to the third conveying groove 41 extends above the base 91. The lifting driving unit 442 drives the lifting seat 441 to move upward, so that the lifting seat 441 lifts the combined carrier 80 in the third conveying groove 41, and the lower surface of the positioning seat 451 abuts against the upper surface of the base 91. The first driving device 421 drives the two first material taking modules 422 to move synchronously. One of the first material taking modules 422 pulls out the crystal carrier 81 in the third conveying groove 41 upward and transfers it to the transfer platform 43, and the other first material taking module 422 transfers the crystal carrier 81 on the transfer platform 43 to the fourth conveying groove 51 on the carrier return mechanism 50.

[0063] The fourth conveying trough 51 conveys the crystal carrier 81 to the carrier handling and cleaning mechanism 60. The second driving device 621 drives the second material taking module 622 and the cleaning module 623 to move synchronously along the Y-axis direction. The second material taking module 622 takes out the crystal carrier 81 in the fourth conveying trough 51 and places it into the accommodating groove 611. The second positioning driving unit 64 drives the positioning rod 641 to extend into the accommodating groove 611 to position the crystal carrier 81. The lifting driving unit 6231 drives the cleaning head 6232 to move downward. The cleaning head 6232 drives the inserting rod 6233 to insert downward into the corresponding guiding hole 811 to push the crystal 90 remaining in the guiding hole 811 outwards. The material pushing driving unit 63 pushes the cleaned crystal carrier 81 out of the accommodating groove 611 onto the fifth conveying trough 71 on the carrier discharging mechanism 70. The fifth conveying trough 71 outputs the cleaned crystal carrier 81 to the next working station, completing the automated production of carrier loading, product welding, carrier separation, carrier reflux, carrier cleaning, and carrier discharging.

[0064] In summary, the present utility model sequentially arranges a carrier loading mechanism 20, a welding conveying mechanism 30, and a carrier separation and handling mechanism 40 on the frame 10. During production, first, the combined carrier 80 is conveyed to the welding conveying mechanism 30 by the carrier loading mechanism 20. Then, the crystal 90 on the combined carrier 80 is welded to the base 91 by the welding conveying mechanism 30, and the combined carrier 80 with the crystal 90 and the base 91 welded is conveyed to the carrier separation and handling mechanism 40. Then, the crystal carrier 81 on the combined carrier 80 can be pulled out upwards by the carrier separation and handling mechanism 40 to separate the crystal carrier 81 from the base carrier 82, thereby realizing an automated production method of carrier loading, product welding, and carrier separation, improving production efficiency and reducing production costs. In addition, by adding a carrier reflux mechanism 50 and a carrier handling and cleaning mechanism 60, the reflux of the crystal carrier 81 and the cleaning of the carrier can be realized.

[0065] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Therefore, any modifications, equivalent replacements, improvements, etc. made to the above embodiments according to the technical reality of the present utility model still fall within the scope of the technical solution of the present utility model.
