The specific structure of the fixture is not described in detail here, and those skilled in the art should be able to design a variety of fixtures that meet this function.

[0054] In the disclosed embodiment, the base loading station b2 is used to load the base onto the fixture passing through; it should be noted that the base is generally placed on a special carrier, and the carrier is grabbed by a special robot and placed on the fixture.

[0055] Secondly, the transparent sheet loading station b3 is used to load the transparent sheet onto the base of the passing fixture; optionally, the transparent sheet is transported through a special vibration plate and a straight vibration track, and after being divided, it is grabbed by a special robot for assembly.

[0057] Secondly, the transmission shaft loading station b5 is used to load transmission shaft one, transmission shaft two and transmission shaft three onto the base of the fixture. The three transmission shafts are the same, so a special vibration plate and straight vibration track can be used for transportation, and then they are divided one by one through the dividing mechanism, and then grabbed one by one by a special robot and plugged into the base. Of course, the three transmission shafts are assembled at the same time. It should be understood that it is only necessary to use a positioning plate set with reference to the base, first install the three transmission shafts in the correct position through the robot, and then use another robot to grab the three accurately positioned transmission shafts at the same time and plug them into the base.

This station can refer to the transmission shaft loading station b5.

[0061] In this way, the automatic assembly of the reclosing module can be realized, which greatly improves the assembly efficiency and ensures the consistency of the product.

[0062] Embodiment 2:

[0063] Based on the first embodiment, in the assembly of the reclosing module, the assembly of the motor and the worm is very important, and it is the most difficult to realize automation. At the same time, if damage occurs, the loss caused is also great. Therefore, in the embodiment of the present disclosure, a motor and worm loading station b10 is specially designed.

[0064] like Figures 2 to 10 As shown, the motor worm feeding station b10 includes a motor carrier, a motor manipulator, a worm vibration plate 1, a worm straight vibration track 2, a worm material dividing mechanism 3, a worm detector 4, a worm manipulator 5, a fixed material channel 6, a rotating material channel 7, an alignment visual detection device 8, a push rod assembly 9, a positioning assembly 10, a worm clamping assembly 11, a worm alignment assembly 12 and a motor worm feeding manipulator; wherein, a plurality of positioning grooves adapted to the motor are arrayed on the motor carrier, and the motor of the motor carrier can be grasped by the motor manipulator.

[0065] Specifically, the worm material dividing mechanism 3 includes a worm material dividing seat 300 and a worm material dividing drive assembly 301. The worm material dividing seat 300 is provided with a first worm positioning groove 302 adapted to the worm. The worm material dividing drive assembly 301 is used to enable the worm material dividing seat 300 to move vertically to have a first position aligned with the worm straight vibration track 2 and a second position that can be grasped by the worm manipulator 5; the worm material dividing drive assembly 301 can adopt a mechanism for driving component translation commonly used in the field of automation technology, for example, a structure in which a driving cylinder cooperates with a guide rail slider, or a structure in which a driving motor cooperates with a screw slider, etc.

[0066] like Figure 3As shown, the worm dividing mechanism 3 also includes a first dividing plate 303 and a second dividing plate 304 which are arranged on one end of the worm direct vibration track 2 close to the worm dividing seat 300, the first dividing plate 303 includes an opening portion 3030 which is connected to the worm direct vibration track 2 and through which the worm can pass, and a first baffle portion 3031 which is located on the upper side of the opening portion 3030, the second dividing plate 304 is formed by a downward protrusion of one end of the worm dividing seat 300 close to the worm direct vibration track 2, and the second dividing plate 304 is connected to the worm direct vibration track 2. The worm material distributor seat 300 can also be detachably connected. When the worm material distributor seat 300 is in the first position, the opening portion 3030 connects the worm straight vibration track 2 and the first worm positioning groove 302. When the worm material distributor seat 300 is in the second position, the second material distributor plate 304 and the opening portion 3030 at least partially overlap. Preferably, the second material distributor plate 304 closes the opening portion 3030. Through this arrangement, one-to-one distribution of the worm is achieved. At the same time, the overall structure is simple and the manufacturing cost is low.

[0067] Secondly, a second baffle portion 305 is provided at one end of the first worm positioning groove 302 away from the opening portion 3030, and a grabbing opening 305 adapted to the worm manipulator 5 is provided on the first baffle portion 3031 and the second baffle portion 305. Through this arrangement, the first baffle portion 3031 and the second baffle portion 305 prevent the worm from moving axially, and the grabbing opening 305 avoids interfering with the grabbing of the worm manipulator 5.

[0068] In the disclosed embodiment, a motor positioning groove 600 adapted to the motor is provided on the fixed material channel 6, and a support rod assembly 602 is provided at the rear end of the fixed material channel 6 toward the motor positioning groove 600. The support rod assembly 602 can position the motor in the motor positioning groove 600. The support rod assembly 602 includes a fixed rod and a positioning rod connected to the fixed material channel 6. The positioning rod is threadedly connected to the front end of the fixed rod. A positioning plate adapted to the motor is provided at the front end of the positioning rod. The positioning rod is adjustable relative to the fixed rod to avoid unstable positioning of the motor due to processing errors.

[0069] The rotating material channel 7 is provided with a second worm positioning groove 700 adapted to the worm, and the motor manipulator is used to grab the motors on the motor carrier one by one to the motor positioning groove 600. The worm detector 4 is arranged at one end of the first worm positioning groove 302, which is used to detect the direction of the worm. The worm detector 4 is arranged at one end of the first worm positioning groove 302 close to the rotating material channel 7. Optionally, the worm detector 4 adopts a photoelectric sensor, a CCD visual detection camera, etc.

[0070] Based on the structural characteristics of the worm, a conventional vibration plate cannot distinguish its front and rear ends. Therefore, the worm is grasped by the worm manipulator 5 and the worm is rotated forward to the second worm positioning groove 700 according to the detection result of the worm detector 4. This arrangement ensures that the worm is in the correct direction after loading, so as to facilitate rapid assembly with the motor.

[0071] Among them, the output shaft of the motor placed in the fixed material channel 6, the mounting hole of the worm placed in the rotating material channel 7 and the alignment visual detection device 8 are coaxially arranged, and the alignment visual detection device 8 is used to detect whether the output shaft of the motor and the mounting hole of the worm are aligned. The alignment visual detection device 8 includes a CCD visual camera 800 and an LED ring light source 801; wherein, based on the shape of the output shaft and the mounting hole, the angle between the straight edges in the cross section of the two can be calculated and then aligned.

[0072] In the embodiment of the present disclosure, the positioning assembly 10 is used to clamp and position the output shaft of the motor and the front bearing seat of the motor; Figure 5 and Figure 6 As shown, the positioning assembly 10 includes a first cylinder 100 and two first clamping blocks 101, and a clamping portion is provided on the side close to the two first clamping blocks 101, and the clamping portion includes a first clamping groove 102 and a second clamping groove 103.

The first clamping groove 102 and the second clamping groove 103 are both triangular, and this shape is conducive to clamping the axial workpiece. Through this arrangement, the output shaft of the motor and the motor are clamped and fixed to prevent them from rotating or deviating when assembled with the worm.

[0073] In the embodiment of the present disclosure, the worm clamping assembly 11 is arranged at the rear end of the rotating material channel 7, and is used to clamp and fix the worm when it is placed in. Specifically, the worm clamping assembly 11 includes two second clamping blocks 110, and a third clamping groove 111 is arranged on the side where the two second clamping blocks 110 are close to each other. The two third clamping grooves 111 are matched to form a third clamping opening 112 adapted to the rear end of the worm, and the third clamping groove 111 is triangular. A movable groove 700 is arranged at the rear end of the rotating material channel 7, and the two second clamping blocks 110 are arranged in the movable groove 700 for transverse sliding. A spring positioning rod 1100 is arranged on the side where the two second clamping blocks 110 are far away from each other, and a first spring 1101 is sleeved on the spring positioning rod 1100, and the first spring 1101 is pressed between the corresponding second clamping block 110 and the movable groove 700. The upper ends of the two second clamping blocks 110 are provided with guiding bevels 113, and the two guiding bevels 113 form a guiding opening 114 for the worm to be inserted, which is conducive to the rapid installation of the worm. The upper and lower sides of the guiding bevels 113 are both provided with arc surfaces 115 to reduce damage to the worm. Through this arrangement, when the worm manipulator 5 grabs the worm and installs it into the second worm positioning groove 700, the two second clamping blocks 110 are stretched open to allow the worm to be inserted. Then, under the action of the first spring 1101, the two second clamping blocks 110 clamp the worm, thus preventing the worm from rotating during assembly, and at the same time, it can drive the worm to rotate synchronously with the rotating material channel 7. Among them, the worm manipulator 5 preferably grabs the front and rear ends of the worm, which not only avoids damage to the worm, but also facilitates easy installation into the second worm positioning groove 700.

[0074] In the disclosed embodiment, the worm alignment assembly 12 is used to rotate the worm so that the mounting hole thereon is aligned with the output shaft of the motor according to the detection result of the alignment visual detection device 8; specifically, the worm alignment assembly 12 includes a base plate 120, a bracket 121 slidably disposed on the base plate 120, a gear plate 122 disposed at the front end of the rotating material channel 7, an alignment motor 123 and a driving gear 124, the gear plate 122 is rotatably disposed on the bracket 121, the alignment motor 123 is disposed on the bracket 121, the driving gear 124 is meshed with the gear plate 122, and a detection hole 125 is disposed in the middle of the gear plate 122, so that according to the detection result of the alignment visual detection device 8, the alignment motor 123 drives the driving gear 124 to rotate so that the mounting hole is aligned with the output shaft.

[0075] The diameter of the gear plate 122 is larger than the diameter of the driving gear 124 , and the diameter of the gear plate 122 is larger than the diameter of the rotating material channel 7 . By setting the transmission ratio between the gear plate 122 and the driving gear 124 , the alignment accuracy can be improved.

[0076] When the two are aligned, the push rod assembly 9 pushes the worm toward the motor to form an assembly, and the motor and worm feeding robot grabs the motor and the worm and moves them to the carrier, and at the same time the positioning assembly 10 and the worm clamping assembly 11 are opened.

[0077] In the embodiment of the present disclosure, the push rod assembly 9 includes a pushing cylinder 900, a guide rail 901 arranged on the bottom plate 120, and a first slide seat 902 and a second slide seat 903 that slide with the guide rail 901. The pushing cylinder 900 drives the first slide seat 902 to move along the slide rail. A first push rod 904 is arranged on the first slide seat 902 toward the second slide seat 903. An active cavity 905 is arranged on the second slide seat 903. A push plate 906 is arranged on the side of the active cavity 905 close to the first slide seat 902. A through hole 907 is arranged on the push plate 906 for the first push rod 904 to pass through. One end of the first push rod 904 passes through the through hole 907 and extends into the active cavity 905 and is provided with a convex plate 908. A number of magnetic parts 909 are evenly arranged along the circumference of the convex disc 908, the push plate 906 is made of a magnetically attracted material, and a second push rod 910 is arranged on the second slide 903 toward the bracket 121. Within a certain driving force, the pushing cylinder 900 can push the first slide 902 to move, and at the same time drive the second slide 903 to move synchronously. When an unexpected situation occurs, such as a processing error between the worm and the output shaft, the worm cannot be inserted into the output shaft. At this time, the movement resistance of the second push rod 910 is greater than the magnetic attraction between the convex disc 908 and the push plate 906, and the convex disc 908 and the push plate 906 will separate to avoid damage to the mechanism and the product due to forced pushing. In addition, the use of a magnetic attraction structure can improve the control accuracy of the movement of the second push rod 910.

[0078] Furthermore, a third spring 911 is provided between the convex disc 908 and the movable cavity 905. After the accident is resolved, the third spring 911 can enable the convex disc 908 to be quickly attracted to the push plate 906, and at the same time, the third spring 911 can prevent the convex disc 908 from moving forward too quickly.

[0079] A mounting frame 601 is provided at the bottom of the fixed material channel 6, and a second spring 912 is provided between the bracket 121 and the mounting frame 601. Under the action of the second spring 912, the bracket 121 is in the loading position, and the push rod assembly 9 pushes the bracket 121 to move to the assembly position; when the worm and the output shaft are assembled, under the action of the second spring 912, the bracket 121 can be automatically reset.

[0080] In the disclosed embodiment, a proximity switch 913 is provided on the second slide 903, and a trigger end of the proximity switch 913 is arranged toward the bracket 121. A trigger plate 914 is provided on the first slide 902, and one end of the trigger plate 914 extends to the front of the trigger end and contacts therewith. When the push rod assembly 9 is operating normally, the proximity switch 913 remains connected to the trigger plate 914. When the convex disc 908 is separated from the push plate 906, the proximity switch 913 is disconnected from the trigger plate 914. Such timely feedback is provided to facilitate timely elimination of faults.

[0081] Optionally, the guide opening 114 in the worm clamping assembly 11 is set to be vertically oriented as a loading and unloading position; at the same time, the two first clamping blocks 101 are each provided with an opening rod 106 facing the corresponding second clamping block 110. When the worm clamping assembly 11 is in the loading and unloading position, the opening rod 106 can be inserted into the third clamping groove 111 of the corresponding second clamping block 110. When the first cylinder 100 drives the two first clamping blocks 101 to open, the two second clamping blocks 110 are opened synchronously, which reasonably utilizes the existing clamping groove structure, saves the driving source, reduces the cost of the entire equipment, and improves the synchronization of the mechanism.

[0082] Furthermore, by setting the length of the opening rod 106, the distance between the front end surface of the front bearing seat a31 and the rear end surface of the worm a4 can also be controlled to meet the standard.

[0083] Embodiment three:

[0084] Based on the first and second embodiments, this embodiment provides a method for assembling a reclosing module of a miniature circuit breaker, comprising the following steps:

[0085] Step S1: The motor on the motor carrier is grabbed by the motor manipulator and placed in the motor positioning slot 600. At this time, the first cylinder 100 drives the two first clamping blocks 101 to close and clamp the output shaft of the motor and the front bearing seat of the motor respectively;

[0086] Step S2: The worm is conveyed to the first worm positioning groove 302 through the worm vibrating plate 1 and the worm direct vibration track 2. At this time, the worm material distribution seat 300 is in the first position, and then the worm detector 4 detects the direction of the worm;

[0087] Step S3: The worm material distribution drive assembly 301 drives the worm material distribution seat 300 to move to the second position, and then the worm manipulator 5 grabs the worm and rotates the worm forward and forward according to the detection result of the worm detector 4 to place it in the second worm positioning groove 700. At this time, the two second clamping blocks 110 clamp and fix the rear end of the worm;

[0088] Step S4: The alignment visual detection device 8 detects the deflection angle of the output shaft of the motor and the mounting hole of the worm; then, it is calculated that the alignment motor 123 should drive the driving gear 124 to rotate forward or reverse to achieve the fastest alignment. Secondly, a memory comparison module is added to record the overlapping graphics of the cross section of the output shaft and the cross section of the mounting hole each time and the adjustment data corresponding to the overlapping graphics. The adjustment data includes the adjustment direction and the adjustment angle. After a certain number of records, the subsequent alignment only needs to compare the new overlapping graphics with the overlapping graphics in the record, and directly retrieve the closest adjustment data within the allowable deviation range, which is executed by the alignment motor 123.

[0089] Step S5: According to the detection result of the alignment visual detection device 8, the alignment motor 123 drives the driving gear 124 to rotate, drives the gear plate 122 to rotate, drives the rotating channel 7 to rotate, and makes the worm thereon rotate until the mounting hole of the worm is aligned with the output shaft of the motor;

[0090] Step S6: The first slide 902 is driven to move by pushing the air cylinder 900, which drives the second slide 903 to move, and drives the rotating material channel 7 to move, so that the worm is pushed into the output shaft of the motor to a certain distance. This distance is no more than half of the length of the motor output shaft, and generally only 1mm-2mm needs to be inserted. This avoids forced assembly of the incompatible output shaft and the mounting hole, which may cause damage to the parts.

[0091] Step S7: The first cylinder 100 drives the two first clamping blocks 101 to separate by a certain distance, and only needs to be slightly separated so that the worm can drive the output shaft to rotate;

[0092] Step S8: The worm clamping assembly 11 is rotated to the loading and unloading position through the worm alignment assembly 12. At this time, the worm drives the output shaft of the motor to rotate together. In this way, there is no need to rotate the worm clamping assembly 11 to the loading and unloading position when the motor worm loading robot is discharging materials. The subsequent motor worm loading robot can discharge materials quickly and minimize the number of rotations and the rotation amplitude of the gear plate 122.

[0093] Step S9: driving the two first clamping blocks 101 to close again by the first cylinder 100;

[0094] Step S10: The first slide 902 is driven to move by pushing the air cylinder 900, which drives the second slide 903 to move, and drives the rotating material channel 7 to move, so that the worm is pushed to continue to be inserted into the output shaft of the motor. At the same time, the two opening rods 106 are respectively extended into the corresponding third clamping grooves 111 until the opening rods 106 are in contact with the rotating material channel 7. At this time, the distance between the rear end face of the worm and the front end face of the front bearing seat of the motor just meets the assembly standard, thereby avoiding assembly errors and further improving the reliability of assembly.

[0095] Step S11: The first cylinder 100 drives the two first clamps 101 to open, and the opening rod 106 drives the two second clamps 110 to open synchronously. The motor worm feeding robot grabs the assembled motor worm and moves it to the carrier.

[0096] In the embodiment of the present disclosure, in step S6, if the worm gear cannot be inserted into the output shaft of the motor, the second push rod 910 is restricted from moving. At this time, the push cylinder 900 drives the first slide 902 to move, and the first push rod 904 drives the convex plate 908 to slide relative to the second slide 903, so that the convex plate 908 is separated from the push plate 906, and the proximity switch 913 is disconnected from the trigger plate 914, thereby reducing the probability of damage to the workpiece and the equipment; further, if this situation occurs, each mechanism is reset and then steps S4, S5 and S6 are executed. When the proximity switch 913 and the trigger plate 914 are disconnected in both alignments, a warning is issued, such as a warning sound, a warning light, etc., to inform the maintenance personnel to repair and troubleshoot in time.
