[0023] The following will describe various embodiments of the present invention in detail with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0024] As attached Figure 1-11 As shown, a vertical sensor automatic assembly equipment includes a dispensing assembly station 1, a production line conveying platform 2, a copper foil soldering station 3, a wire welding and hot riveting station 4, and an automatic screwing station 5. The dispensing assembly station 1 is provided with a loading station 47, a dispensing station 48, a plastic sheath installation station 49, and a unloading station 50 in accordance with the action flow. The unloading station 50 is connected to the input end of the production line conveying platform 2. The copper foil soldering station 3 includes a loading mechanism, a grinding station, a copper foil pasting station, a soldering station, and an unloading mechanism. The input end of the mechanism is connected to the output end of the assembly line conveying platform 2. The welding wire and hot riveting station 4 includes a welding platform and a hot riveting platform arranged in sequence. The unloading mechanism is connected to the welding platform through a conveyor belt. The automatic screwing station 5 includes a shell conveyor line and a screwing platform that cooperate with each other. The welding wire and hot riveting station 4 and the automatic screwing station 5 are connected in series through a conveyor belt. This overall layout design makes the sensor assembly process highly automated, from loading raw materials to unloading finished products, which can greatly reduce manual intervention and greatly improve production efficiency and assembly accuracy.

[0025] The dispensing assembly station 1 includes a cylinder 6, a rotating disk 7 is rotatably installed inside the cylinder 6, and four placement plates 8 are fixedly embedded inside the rotating disk 7. The four placement plates 8 correspond to the loading position 47, the dispensing position 48, the plastic sheath installation position 49 and the unloading position 50 respectively. Each placement plate 8 is provided with a positioning mechanism, which includes four moving plates 9 slidably connected to the inside of the placement plate 8, and the four moving plates 9 are distributed in a circular array, two of which are symmetrical. The sides of the moving plates 9 close to the center of the placement plate 8 are fixedly connected to the first positioning rod 10, and the other two symmetrical moving plates 9 close to the center of the placement plate 8 are fixed. A second positioning rod 11 is fixedly connected, and the other ends of the two first positioning rods 10 and the two second positioning rods 11 are fixedly connected to a ball cover 12. A positioning ball 13 is rotatably installed inside the ball cover 12. When the four placement plates 8 rotate with the rotating disk 7, they can pass through four workstations in turn to form a periodic operation. The four movable plates 9 are distributed in a circular array and can simultaneously press against the U-shaped iron core from four directions to ensure that the center of the iron core is aligned with the center of the placement plate 8. The positioning ball 13 can only rotate horizontally in the ball cover 12 and cannot rotate up and down, which can not only avoid damage to the iron core caused by hard contact, but also prevent the iron core from shifting during processing.

[0026] A rectangular column 14 is fixedly connected to the center of the bottom surface of the placement plate 8, and four springs 15 are fixedly connected to the outer surface of the rectangular column 14. The other ends of the four springs 15 are fixedly connected to the four movable plates 9 respectively. When the springs 15 are in a natural state, the movable plate 9 drives the positioning ball 13 to be in the initial position, which is convenient for iron core loading; when the first wedge plate 21 squeezes the second wedge plate 22 to make the movable plate 9 slide inward, the spring 15 is compressed and stores elastic potential energy. When the external force is removed, the spring 15 releases the potential energy to push the movable plate 9 to reset, thereby realizing the automatic release of the positioning ball 13.

[0027] The interiors of the four movable plates 9 are all slidably connected with sliding rods 23, one end of the sliding rod 23 is fixedly connected to a circular plate, and the other end is fixedly connected to a second wedge plate 22. A lifting plate 16 is provided below the placement plate 8, and the upper surface of the lifting plate 16 is fixedly connected to four connecting rods 19 distributed in a circular array, and the other end of the connecting rod 19 is fixedly connected to a connecting block 20. A surface of the connecting block 20 close to the center of the placement plate 8 is fixedly connected to a first wedge plate 21 adapted to the second wedge plate 22. The inclined surfaces of the first wedge plate 21 and the second wedge plate 22 cooperate to convert the vertical movement of the lifting plate 16 into horizontal movement of the movable plate 9.

[0028] A counterweight ring 17 is fixedly connected to the edge of the bottom surface of the lifting plate 16, and a lifting rod 18 is fixedly connected to the center of the bottom surface of the lifting plate 16. The gravity of the counterweight ring 17 is much greater than the elastic force of the spring 15. Therefore, when the lifting rod 18 loses its blocking force, the counterweight ring 17 can overcome the elastic force and drive the lifting plate 16 to move downward.

[0029] A driving mechanism corresponding to the positioning mechanism is provided below the rotating disk 7. The driving mechanism includes a first curved plate 26, a second curved plate 27, a third curved plate 28 and a fourth curved plate 29 fixedly connected to the inner bottom wall of the cylinder 6. The first curved plate 26, the second curved plate 27, the third curved plate 28 and the fourth curved plate 29 are connected end to end to form a complete circle, and the first curved plate 26 corresponds to the loading position 47, the second curved plate 27 corresponds to the dispensing position 48, the third curved plate 28 corresponds to the plastic sheath installation position 49, and the fourth curved plate 29 corresponds to the unloading position 50. Correspondingly, the first curved plate 26, the second curved plate 27, the third curved plate 28 and the fourth curved plate 29 are all provided with track grooves adapted to the lifting rod 18, and the lifting rod 18 is slidably connected to the inside of the track groove. The annular track groove composed of the four curved plates matches the rotation trajectory of the rotating disk 7. When the rotating disk 7 drives the lifting rod 18 to rotate along the track groove, the height change of the track groove can drive the lifting rod 18 to move up and down, so that the positioning mechanism automatically executes the cycle of "loosening the loading → clamping the glue → keeping the installation sheath fixed → loosening the unloading" at different workstations.

[0030] When the second supporting plate 31 is rotated, the slope becomes higher and the lifting rod 18 rises, and the first wedge plate 21 moves away from the second wedge plate 22, and the spring 15 drives the positioning ball 13 to reset.

[0031] The driving mechanism also includes a first transmission shaft 39 rotatably mounted on the inner bottom wall of the cylinder 6. The top end of the first transmission shaft 39 is fixedly connected to the bottom surface of the rotating disk 7. The inner bottom wall of the cylinder 6 is mounted with a motor 33. The outer surface of the output end of the motor 33 is mounted with a first one-way bearing 34. The outer surfaces of the first one-way bearing 34 and the second transmission shaft 41 are both mounted with first synchronous wheels 35. The two first synchronous wheels 35 are connected by a first synchronous belt transmission. When the motor 33 rotates in the reverse direction, the first one-way bearing 34 is locked, and the first transmission shaft 39 is driven to rotate by the first synchronous wheel 35 and the first synchronous belt, so that the rotating disk 7 rotates in the set direction; when the motor 33 rotates in the forward direction, the first one-way bearing 34 is idling, and the rotating disk 7 remains stationary.

[0032] An adjusting mechanism corresponding to the positioning mechanism is provided below the rotating disk 7. The adjusting mechanism includes a right-angle plate 46 fixedly connected to the inner bottom wall of the cylinder 6, and a second transmission shaft 41 is rotatably installed between the right-angle plate 46 and the inner bottom wall of the cylinder 6. A second one-way bearing 44 is installed on the outer surface of the output end of the motor 33, and a second synchronous wheel 45 is installed on the outer surface of the second one-way bearing 44 and the second transmission shaft 41. The two second synchronous wheels 45 are connected by a second synchronous belt transmission. A reciprocating screw rod 42 is rotatably installed inside the right-angle plate 46, and the reciprocating screw rod 42 is fixedly connected to the end close to each other of the second transmission shaft 41. The outer surface of the reciprocating screw rod 42 is threadedly connected to a threaded plate 43, and the upper surface of the right-angle plate 46 is fixedly connected to a guide plate, and the threaded plate 43 is slidably connected to the guide plate. When it is necessary to adapt to different types of iron cores, the motor 33 is controlled to rotate forward, the second one-way bearing 44 is locked, and the second transmission is driven by the second synchronous wheel 45. The shaft 41 rotates, causing the reciprocating screw 42 to rotate. The threaded plate 43 is driven by the reciprocating screw 42 to move up and down along the guide plate, thereby driving the support block 40, the cross plate 24 and the second wedge plate 22 to move, and adjusting the initial distance between the second wedge plate 22 and the first wedge plate 21. For example, if the first wedge plate 21 and the second wedge plate 22 are in contact in the initial state, the first wedge plate 21 moves downward by ten centimeters, which can cause the second wedge plate 22 to move horizontally by ten centimeters. If the second wedge plate 22 is moved down by two centimeters through adjustment, the first wedge plate 21 needs to move downward by two centimeters to contact the second wedge plate 22, and then continue to move eight centimeters to reach the maximum stroke. At this time, the second wedge plate 22 only moves horizontally by eight centimeters, thereby reducing the movement range of the positioning ball 13 and adapting to small-sized iron cores. Conversely, if the second wedge plate 22 is moved upward, the movement range of the positioning ball 13 can be expanded to adapt to large-sized iron cores, thereby realizing universal adjustment of the equipment for iron cores of different models.

[0033] The threaded plate 43 is fixedly connected to the support block 40 on one side away from the guide plate, and a support ring 37 is rotatably installed inside the support block 40. The round seat 36 is fixedly connected to the inside of the support ring 37, and a through hole is opened inside the round seat 36 for the first transmission shaft 39 to pass through. The outer surface of the round seat 36 is fixedly connected to the Z-shaped plate 38, and the other side of the Z-shaped plate 38 is fixedly connected to the cross plate 24. The cross plate 24 is slidingly connected to the second wedge plate 22 through the L-shaped plate 25. The L-shaped plate 25 is slidably connected to the inside of the cross plate 24 and fixedly connected to the second wedge plate 22. Through the cooperation between the support block 40, the support ring 37, the round seat 36, the Z-shaped plate 38, the cross plate 24 and the L-shaped plate 25, the second wedge plate 22 can be driven to move up and down without affecting the rotation and horizontal movement of the second wedge plate 22.

[0034] Working principle: When assembling the sensor, first adjust the distance between the first wedge plate 21 and the second wedge plate 22 according to the model of the U-shaped iron core, and control the motor 33 to rotate forward. The forward rotation of the motor 33 can drive the second one-way bearing 44 and the second synchronous wheel 45 to rotate as a whole. At this time, the first one-way bearing 34 will only idle, and the second synchronous wheel 45 can drive the second transmission shaft 41 and the reciprocating screw 42 to rotate. The rotation of the reciprocating screw 42 can drive the threaded plate 43 to move up and down along the reciprocating screw 42. The movement of the threaded plate 43 can drive the support block 40, the round seat 36, the cross plate 24 and the second wedge plate 22 to move accordingly, so that the distance between the second wedge plate 22 and the first wedge plate 21 can be adjusted.

[0035] After the adjustment is completed, the iron core is placed on the placement plate 8 corresponding to the loading position 47 and the iron core is located between the four positioning balls 13. The length direction of the iron core corresponds to the second positioning rod 11, and the width direction corresponds to the first positioning rod 10. Then the motor 33 is controlled to rotate in the opposite direction. The reverse rotation of the motor 33 can drive the first one-way bearing 34 and the first synchronous wheel 35 to rotate as a whole. At this time, the second one-way bearing 44 will only rotate idly, and the rotation of the first synchronous wheel 35 can drive the first transmission shaft 39, the rotating disk 7, the placement plate 8, the lifting disk 16 and the lifting rod 18 to rotate as a whole. When the lifting rod 18 rotates along the first push rod plate 30, and since the slope of the first push rod plate 30 gradually becomes lower along the direction of rotation of the placement plate 8, under the action of the counterweight ring 17, the lifting plate 16 and the connecting block 20 will gradually move downward. When the first wedge plate 21 moves to contact the second wedge plate 22, it continues to move downward to squeeze the second wedge plate 22 to slide inward and compress the spring 15. The inward sliding of the second wedge plate 22 can drive the four positioning balls 13 to move inward at the same time, so that the iron core can be positioned at the center of the placement plate 8 and clamped and fixed.

[0036] After that, the rotary disk 7 continues to rotate to transport the placement plate 8 to the dispensing position 48. After the dispensing is completed, the rotary disk 7 continues to rotate to transport the placement plate 8 to the plastic sheath installation position 49. After the installation is completed, the rotary disk 7 continues to rotate to drive the lifting rod 18 to rotate along the second support plate 31. Since the slope of the second support plate 31 gradually becomes higher along the direction of rotation of the placement plate 8, the second support plate 31 can squeeze the lifting rod 18 and the first wedge plate 21 to move upward. At this time, under the action of the spring 15, the second wedge plate 22 will drive the positioning ball 13 to gradually move outward to reset. When the placement plate 8 moves to the unloading position 50, the placement plate 8 can be completely released. The fixation of the placement plate 8 can be transferred to the input end of the assembly line conveying platform 2 by the manipulator. Then the rotary disk 7 continues to rotate to drive the lifting rod 18 to rotate along the arc support plate 32, so that when it rotates to the loading position 47, the positioning ball 13 is in the initial state, which is more convenient for loading.
