Detailed implementation manners

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] In addition, the elements in the present invention are referred to as "fixed to" or "disposed on" another element, which can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation.

[0029] Please refer to Figures 1-10 , in the embodiment of the present invention, a lead welding device based on multi-station positioning includes a cabinet 31. Four stations are equidistantly arranged along the circumference inside the cabinet 31, which are a loading station, a welding station, an inspection station, and a unloading station in sequence. The lead welding device based on multi-station positioning further includes: a turntable 1 rotatably installed inside the cabinet 31. Four mounting seats 2 are fixedly arranged equidistantly along the circumference on the turntable 1. A supporting seat 3 for receiving the chip to be welded is fixed on the side of the mounting seat 2. A pushing mechanism is further provided on the mounting seat 2. The pushing mechanism works when it is located at the unloading station, and is used to push the chip that has completed welding and inspection off the supporting seat 3. The pushing mechanism cooperates with a pressing mechanism arranged on the top wall of the cabinet 31. A loading mechanism is installed inside the cabinet 31 and is located at the loading station. The loading mechanism is used to convey the chip to the supporting seat 3 and cooperate with the pressing mechanism. The loading mechanism is further connected with a one-way transmission mechanism, and the one-way transmission mechanism is triggered after the chip conveying is completed and prompts the turntable 1 to rotate 90°.

[0030] It should be added that, please refer to Figure 4 , the loading station is located on one side of the turntable 1 facing the bracket 9, and the welding station, the inspection station, and the unloading station are circularly distributed in sequence along the clockwise direction starting from the loading station.

[0031] Furthermore, the cabinet body 31 is also provided with a welding module and a detection module, which are respectively located at the welding station and the detection station. Specifically, the welding module is used to complete the lead welding work of the chip, and the detection module is used to detect the welding situation. Both adopt existing automation technologies, and this application will not elaborate on them here. During operation, the loading mechanism works to convey chips to the carrier 3 located at the loading station. At the same time, the chips located at the welding station complete the lead welding process, and the chips located at the detection station undergo welding detection. Moreover, the loading mechanism cooperates with the pressing mechanism, and the pressing mechanism prompts the pushing mechanism to trigger. The pushing mechanism pushes the chips in the carrier 3 located at the unloading station down. After the chip conveyance is completed, the unloading mechanism causes the turntable 1 to rotate by 90° through the one-way transmission mechanism, realizing the sequential conversion of the chips among the four stations.

[0032] In addition, it should be supplemented that a corresponding transfer manipulator is also provided inside the cabinet body 31. Whenever the unloading is completed, the transfer manipulator is used to transfer the chips that have completed welding and detection.

[0033] Please refer to Figures 4-8 again. The loading mechanism includes a bracket 9 fixed inside the cabinet body 31 and a storage box 10 provided on the bracket 9 for stacking and placing chips. Two strip-shaped through grooves 901 are provided on the bracket 9. The loading mechanism further includes a transverse moving plate 13 movably arranged at the lower part of the bracket 9 through two sets of screw driving components. Two vertical arms 16 adapted to the strip-shaped through grooves 901 are provided on the transverse moving plate 13 through two sets of elastic connection components, and the vertical arms 16 penetrate through the strip-shaped through grooves 901.

[0034] In detail, the threaded drive assembly includes a screw rod 12 rotatably installed at the bottom of the bracket 9 and a driving motor 11 installed at the bottom of the bracket 9, the screw rod 12 is connected to the output end of the driving motor 11, and the screw rod 12 passes through the transverse plate 13, and the transverse plate 13 is threadedly connected to the screw rod 12. When the driving motor 11 drives the screw rod 12 to rotate forward, the transverse plate 13 can be threadedly matched with the screw rod 12 and drive the two vertical arms 16 to move along the strip-shaped through groove 901 through the elastic connection assembly, and then the two vertical arms 16 can move the chip located at the bottom layer of the storage box 10, so that the chip moves toward the upper layer located at the upper layer. The vertical arm 16 moves on the supporting seat 3 on the material station, and finally the chip is transferred to the supporting seat 3 for subsequent welding and testing; in addition, after the vertical arm 16 reaches the end of the movement stroke, the elastic connection component is triggered, causing the vertical arm 16 to move downward, and the vertical arm 16 is withdrawn from the strip through groove 901. After the chips on the welding station and the chips on the testing station are processed accordingly, the drive motor 11 drives the screw rod 12 to rotate in the opposite direction, and the vertical arm 16 moves away from the turntable 1 and resets to the initial position. During this process, the one-way transmission mechanism is triggered, causing the turntable 1 to complete a 90° rotation, so that the chip can switch positions one by one among the four stations for different processing.

[0035] The elastic connection component includes a column 14 slidably arranged on the transverse plate 13, a second cylindrical spring 15 sleeved on the outer periphery of the column 14, the vertical arm 16 is fixed to the upper end of the column 14, and the lower end of the column 14 is fixedly connected to a cross column 17; wherein, the two ends of the cross column 17 are respectively connected to a group of limiting structures installed on the bracket 9, and a round table 1401 is also fixedly provided on the column 14, one end of the second cylindrical spring 15 is connected to the round table 1401, and the other end is connected to the transverse plate 13.

[0036] The limiting structure includes a limiting plate 19 fixedly mounted on the bracket 9, and a groove body adapted to the transverse column 17 is provided on the limiting plate 19, and the transverse column 17 extends into the groove body and is slidably connected with the limiting plate 19; the groove body includes a first groove 1901, a second groove 1902, a third groove 1903, a fourth groove 1904 and a fifth groove 1905 that are connected to each other, and the end of the fifth groove 1905 away from the fourth groove 1904 is connected to the connection between the first groove 1901 and the second groove 1902, and a movable part 20 is hinged in the end of the fifth groove 1905 away from the fourth groove 1904, and the rotating axis of the movable part 20 is connected to a torsion spring.

[0037] During loading, during the forward working process of the threaded drive assembly, the movable part 20 cannot deflect downward in the fifth groove 1905, so the cross column 17 moves along the first groove 1901 and the second groove 1902. At this time, the two vertical arms 16 can smoothly push the chips at the bottom layer in the storage box 10 into the supporting seat 3 located on the loading station. After this section of movement is completed, the cross column 17 reaches the connection between the second groove 1902 and the third groove 1903. At this time, the second cylindrical spring 15 in a compressed state rebounds, so that the cross column 17 switches to the connection between the third groove 1903 and the fourth groove 1904. Accordingly, the vertical column 14 drives the vertical arm 16 downward. When the screw drive assembly works in the reverse direction, the vertical arm 16 is pulled out from the strip through groove 901, so that the vertical arm 16 can be smoothly reset when the screw drive assembly works in the reverse direction. When the screw drive assembly works in the reverse direction, the horizontal column 17 moves along the fourth groove 1904 toward the fifth groove 1905. When the horizontal column 17 moves in the fifth groove 1905, it will slide with the limiting plate 19, and then the horizontal column 17 moves upward, and the horizontal column 17 causes the movable part 20 to deflect upward. The horizontal column 17 is reset to the end of the first groove 1901 away from the second groove 1902, and the vertical arm 16 is reinserted into the strip through groove 901, and the movable part 20 is deflected and reset under the action of the torsion spring.

[0038] Please refer again Figure 5 The one-way transmission mechanism includes a ratchet 21 fixedly mounted on the rotating shaft of the turntable 1 and a ratchet plate 18 fixedly connected to the transverse plate 13. When the transverse plate 13 moves away from the turntable 1, the ratchet on the ratchet plate 18 can cooperate with the ratchet 21 to cause the turntable 1 to rotate, and the rotating shaft of the turntable 1 is also connected to an elastic positioning structure.

[0039] Please refer again Figure 3 and Figure 10 The elastic positioning structure includes a guide cylinder 24 fixed on the rotating shaft of the turntable 1, a telescopic rod 25 slidably fitted with the guide cylinder 24, and a roller 22 arranged at one end of the telescopic rod 25 located outside the guide cylinder 24, and the end of the telescopic rod 25 away from the roller 22 is fixed to a boss 2401 slidably arranged in the guide cylinder 24; a third cylindrical spring 23 is also provided inside the guide cylinder 24 and is sleeved on the outer periphery of the telescopic rod 25, and the two ends of the third cylindrical spring 23 are respectively connected to the inner wall of the guide cylinder 24 and the boss 2401, and a ring body 26 concentric with the turntable 1 is also fixed in the cabinet 31, and four limiting protrusions 2601 are equidistantly provided on the ring body 26 along the circumference, and the roller 22 abuts against the limiting protrusion 2601.

[0040] When the screw drive assembly works forward, the ratchet plate 18 moves together with the transverse movement plate 13. During this process, the ratchet wheel 21 does not rotate. On the contrary, when the screw drive assembly works in reverse, when the ratchets on the ratchet plate 18 pass through the ratchet wheel 21, they will cooperate with the ratchet wheel 21 to cause the ratchet wheel 21 to drive the turntable 1 to rotate by 90°. Further, the limiting protrusion 2601 is arranged in a shape similar to "U", with a notch adapted to the roller 22 formed in the middle part and inclined surfaces formed on both sides. Whenever the turntable 1 rotates, the roller 22 will switch to the notch in the middle part of an adjacent limiting protrusion 2601. Under the elastic action of the third cylindrical spring 23, it can effectively position the turntable 1 and ensure the accuracy of the deflection of the turntable 1.

[0041] Please refer to again Figure 4 、 Figure 5 and Figure 7 , the material pushing mechanism includes two guide columns 4 fixed on the mounting base 2, a lifting plate 5 slidably connected to the two guide columns 4, and a push plate 8 slidably fitted in the supporting base 3; a first cylindrical spring 6 is sleeved on the outer periphery of the guide column 4, and both ends of the first cylindrical spring 6 are respectively connected to the mounting base 2 and the lifting plate 5, and the lifting plate 5 is connected to the push plate 8 through a connecting rod 7. Both ends of the connecting rod 7 are rotatably connected to the lifting plate 5 and the push plate 8 respectively. A protruding plate member 501 cooperating with the pressing mechanism is also fixedly provided on the side of the lifting plate 5.

[0042] The pressing mechanism includes a guide plate 29 fixed on the top wall of the cabinet body 31 and a sleeve plate 30 slidably sleeved with the guide plate 29. The sleeve plate 30 is connected to the transverse movement plate 13 through a sliding fit structure, and a pressing arm 3001 cooperating with the protruding plate member 501 is fixedly provided on one side of the sleeve plate 30 facing the blanking station. The sliding fit structure includes a follower rod 27 fixedly connected to the transverse movement plate 13 and two driven plate members 28 fixedly installed on the sleeve plate 30. A driving column 2701 is fixed at one end of the follower rod 27 away from the transverse movement plate 13. A sliding groove adapted to the driving column 2701 is provided on the driven plate member 28. The driving column 2701 passes through the sliding groove and is slidably connected to the driven plate member 28. The sliding groove includes a connected straight through groove 2801 and an inclined through groove 2802.

[0043] During the forward operation of the screw drive assembly, the follower rod 27 moves together with the transverse movement plate 13. Then, the drive column 2701 slides successively in the flat through slot 2801 and the inclined through slot 2802. The drive column 2701 will be in sliding fit with the driven plate member 28 through the inclined through slot 2802. Thus, it prompts the driven plate member 28 to drive the sleeve plate 30 to move downward on the guide plate 29. Correspondingly, the pressing arm 3001 presses the lifting plate 5 downward through the protruding plate member 501. The lifting plate 5 slides up and down on the two guide columns 4, and pushes the push plate 8 to slide away from the mounting seat 2 in the supporting seat 3 through the connecting rod 7. The push plate 8 then pushes out the chip that has been welded and detected to complete the blanking.
