[0072] The present application provides an assembly tool, which solves the problem of high labor costs and improves assembly efficiency.

[0073] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

Specifically, the rotating mechanism 3 includes a turntable 31, on which a plurality of working grooves 32 are arranged. Through the rotation of the turntable 31, each working groove 32 can at least be switched in sequence among the base loading station A, the nut loading station B, and the unloading station C; the base loading mechanism 4 is located at the base loading station A, and is used to convey the base 1 to the working groove 32; the nut loading mechanism 5 is located at the nut loading station B, and is used to convey the nut 2 to the working groove 32, and can align the nut 2 on the protruding stud 11 of the base 1; the unloading mechanism 6 is located at the unloading station C, and the unloading mechanism 6 is used to unload the assembled base 1 and nut 2. In this way, automatic loading and unloading can be achieved at the base loading station A, the nut loading station B, and the unloading station C, thereby reducing labor costs and improving assembly efficiency.

[0075] Further, such as Figure 7 and Fig. 9 As shown, the bottom of each working groove 32 is provided with a telescopic component 7 that rotates synchronously with the working groove 32; when located at the base loading station A and the unloading station C, the telescopic component 7 does not protrude from the bottom of the working groove 32; when located at the nut loading station B, the telescopic component 7 can protrude from the bottom of the working groove 32 and pass through the stud 11 and extend into the nut 2. When located at the base loading station A, the base 1 needs to be transported to the working groove 32, and the telescopic component 7 does not protrude from the bottom of the working groove 32 to avoid the telescopic component 7 blocking the loading of the base 1. Correspondingly, when located at the unloading station C, the assembled base 1 and nut 2 need to be unloaded, and the telescopic component 7 does not protrude from the bottom of the working groove 32 to avoid the unloading being unable to be completed; when located at the nut loading station B, the telescopic component 7 needs to extend the stud 11 so as to extend into the nut 2 to take the nut 2. The telescopic assembly 7 rotates synchronously with the turntable 31 . The telescopic assembly 7 can extend to different lengths depending on the workstation, so as to adapt to different workstations.

[0076] Furthermore, Figure 5-Figure 7As shown, it also includes a first slide rail 8 arranged at the bottom of the turntable 31, and the telescopic component 7 includes a first telescopic component 71 that can slide along the first slide rail 8, and the first telescopic component 71 includes: a fixed pin 711, which is fixedly arranged at the bottom of the working groove 32; a first pin 712, including a sliding ball head 7121, a pin shaft 7122 connected to the sliding ball head 7121, the pin shaft 7122 is penetrated by the fixed pin 711 and can pass through the stud 11, the sliding ball head 7121 is located outside the bottom end of the fixed pin 711, and the pin shaft 7122 can be telescoped relative to the top end of the fixed pin 711; a first elastic member 713, which is engaged between the bottom end of the fixed pin 711 and the sliding ball head 7121, and the sliding ball head 7121 is pressed down by the first elastic member 713, so that the sliding ball head 7121 is always in contact with the first slide rail 8; wherein, when located at the base loading station A and the unloading station C, the first pin 712 does not protrude from the bottom of the working groove 32.

[0077] It should be noted that a first through hole is provided at the bottom of each working groove 32, a second through hole is provided in the axial direction of the stud 11, and a third through hole is provided in the axial direction of the fixed pin 711. The first through hole, the second through hole and the third through hole are aligned so that the pin shaft 7122 can pass through. Preferably, the first slide rail 8 is composed of a smoothly connected curved surface. When the turntable 31 rotates, the sliding ball head 7121 always abuts against the first slide rail 8, and the top of the pin shaft 7122 is extended and retracted relative to the fixed pin 711. When the sliding ball head 7121 is at different heights of the first slide rail 8, the length of the pin shaft 7122 extending from the top of the fixed pin 711 is different. When located at the loading station A and the unloading station C of the base, the first pin 712 does not protrude from the bottom of the working groove 32, so as to facilitate loading and unloading.

[0078] In a certain example, the height of the first slide rail 8 is lowest at the base loading station A and the unloading station C, and is highest at the nut loading station B.

[0079] In some other optional embodiments, the assembly tool may not include the first slide rail 8. Possibly, the extension length of the first pin 712 can be controlled by a switch, that is, two switches are set on the telescopic assembly 7, one of which is used to control the extension length of the first pin 712 located at the base loading station A and the unloading station C, and the other switch is used to control the extension length of the first pin 712 located at the nut loading station B.

[0080] Furthermore, Figure 5-Figure 7As shown, a second slide rail 9 is arranged between the turntable 31 and the first slide rail 8, the telescopic assembly 7 includes a second telescopic assembly 72 that can slide along the second slide rail 9, the circumferential wall of the fixing pin 711 is provided with a first strip hole along the axial direction, the circumferential wall of the first pin 712 is provided with a second strip hole along the axial direction, and the second telescopic assembly 72 includes: a second pin 721, which is arranged in the pin shaft 7122 and can be telescoped relative to the top end of the pin shaft 7122; a second elastic member 722, which is arranged in the pin shaft 7122 and is located between the sliding ball head 7121 and the bottom end of the second pin 721, so that the second The second pin 721 extends out of the top of the pin shaft 7122 under the drive of the second elastic member 722; the slider 723 is arranged on the circumferential wall of the second pin 721 and passes through the second strip hole and the first strip hole. The second elastic member 722 squeezes the second pin 721 so that the slider 723 always abuts against the bottom of the second slide rail 9; wherein, when located at the base loading station A and the unloading station C, the second pin 721 does not protrude from the top of the first pin 712, and when located at the nut loading station B, the second pin 721 extends out of the top of the first pin 712 and passes through the stud 11 and extends into the nut 2. It should be noted that the pin shaft 7122 is provided with a fourth through hole in the axial direction, the bottom end of the pin shaft 7122 is blocked by the sliding ball head 7121, and the second pin 721 extends into the pin shaft 7122 from the top of the pin shaft 7122 in the shape of a rod. Preferably in the present application, the second slide rail 9 located at the nut loading station B changes suddenly in the height direction, and the second slide rail 9 located at other stations is composed of smoothly connected curved surfaces, and as the turntable 31 rotates, the second pin 721 is lifted by the second elastic member 722, so that the slider 723 always abuts against the bottom of the second slide rail 9. In a certain example, the height of the second slide rail 9 has the lowest position at the base loading station A and the unloading station C, and has the highest position at the nut loading station B. Therefore, when located at the base loading station A and the unloading station C, the second pin 721 does not protrude from the top of the first pin 712, and when located at the nut loading station B, the second pin 721 extends out of the top of the first pin 712 and passes through the stud 11 and extends into the nut 2.

[0081] It should be noted that the second slide rail 9 is fixedly connected to the support member located at the bottom of the turntable 31 through a connecting member, so that the second slide rail 9 is fixedly arranged at the bottom of the turntable 31.

[0082] In some other optional embodiments, the assembly tool may not include the second slide rail 9, that is, the extension length of the second pin 721 can be controlled by a switch, that is, two switches are set on the telescopic component 7, one of which controls the extension length of the second pin 721 located at the loading station A and the unloading station C of the base, and the other switch is used to control the extension length of the second pin 721 located at the nut loading station B.

[0083] In some optional embodiments, such as Figure 1 and Figure 3As shown, the nut feeding mechanism 5 includes: a nut box 51, which is used to accommodate the nut 2 and is provided with an opening allowing the nut 2 to pass through; a nut conveying track 52, which is arranged below the opening and includes two tracks, and the nut 2 passing through the opening is supported by the two tracks and slides under the action of gravity; a blocking member 53, which is connected to the nut box 51 and is located at the ends of the two tracks so that the nut 2 can fall on the stud 11. It should be noted that the two tracks are arranged to be inclined downward. Through the above arrangement, the automatic feeding of the nut 2 is achieved, thereby reducing labor and labor costs.

[0084] In some other optional embodiments, the nut feeding mechanism 5 may also use a robot to feed the nuts 2, or the nut feeding mechanism 5 may no longer be provided with a nut conveying track 52, that is, the opening of the nut box 51 is set directly above the stud 11, so that the nut 2 falls directly above the stud 11 after passing through the opening.

[0085] In some optional embodiments, such as Figure 1 , Figure 3 As shown, a positioning member 54 is provided at the bottom of the nut box 51, and the positioning member 54 is used to position the nut 2 at the nut loading station B to prevent the nut 2 from being separated from the base 1. When the telescopic assembly 7 is extended into the nut 2, the positioning member 54 can abut against the top of the nut 2 to prevent the telescopic assembly 7 from lifting the nut 2 and separating from the base 1.

[0086] In some optional embodiments, such as Figure 2 As shown, the base loading mechanism 4 includes: a conveying platform 41, in the conveying direction, the conveying platform 41 has a first side wall and a second side wall arranged opposite to each other, the first side wall is provided with a first opening, the second side wall is provided with a second opening, the first opening is used for the base 1 to enter the conveying platform 41, and the second opening is used for the base 1 to be conveyed to the working groove 32; an auxiliary conveying structure 42 is provided at the second opening, and conveys the base 1 to the working groove 32 aligned with the second opening by rotating. In this way, automatic loading of the base 1 is realized, labor costs are reduced, and efficiency is improved.

[0087] In the present application, preferably, along the conveying direction, the length of the first opening is greater than F (mentioned below), and the length of the second opening matches the width of the base 1 .

[0088] Further, such as Fig. 9 and Fig.12As shown, the conveying platform 41 includes a belt for conveying the base 1, a third side wall connected to the first side wall and the second side wall, and a fourth side wall arranged opposite to the third side wall, and the third side wall is arranged near the second opening; the base feeding mechanism 4 also includes a positioning component 43 to align the base 1, and the positioning component 43 includes: anti-skid patterns arranged on the belt, with an angle of 40°-50° with the conveying direction, and the base 1 is subjected to the friction of the anti-skid patterns; a first positioning member 431, which is composed of the first side wall; a second positioning member 432, which is parallel to the first positioning member 431 The third aligning member 433 is arranged in a row, and one end is connected to the fourth side wall of the conveying platform 41, and the other end is spaced from the third side wall to allow the base 1 to pass through and enter the working groove 32 through the second opening. The distance between the second aligning member 432 and the first aligning member 431 is D. Along the length direction of the base 1, the base 1 has a first arc edge and a second arc edge that are relatively arranged. The distance between the stud 11 and the first arc edge is E, and the distance between the stud 11 and the second arc edge is F, wherein E≤D<F; the third aligning member 433 is composed of the base 1 located downstream in the conveying direction.

[0089] It should be noted that the distance E between the stud 11 and the first arc edge refers to the distance between the stud 11 and the farthest point of the first arc edge.

[0090] For the sake of convenience of explanation, the part of the stud 11 away from the first arc edge is called the first part; the part of the stud 11 away from the second arc edge is called the second part; the second part first enters the base 1 of the belt and can be regarded as the aligned base 1 so that the first through hole opened on the working groove 32 is aligned with the second through hole on the stud 11 so as to cooperate with the telescopic component 7.

[0091] When the base 1 is placed on the belt, it is possible that the first part first enters the belt (the base 1 needs to be aligned at this time), wherein when the base 1 is transported along the conveying platform 41 through the first opening, the first alignment member 431 applies a force in a first direction to the base 1 that needs to be aligned (such as Fig.12 The base 1 is rotated around the first point until the length direction of the base 1 is consistent with the conveying direction, and the stud 11 is abutted by the second aligning member 432 and intersects with the base 1 to be aligned at a second point. The second aligning member 432 applies a force in a second direction to the base 1 to be aligned (not shown in the figure, it is applied in the direction of the stud 11 toward the first side wall). When the base 1 to be aligned contacts the third aligning member 433, the third aligning member 433 applies a reverse force to the base 1 in the opposite direction to the conveying direction (such as Fig.12 F3 shown in the figure, when the reverse force and the friction force (such as Fig.12 Under the joint action of F1) shown in FIG. 1 , the body 12 of the base 1 rotates around the second point to make the base 1 straight.

[0092] The setting of the alignment component 43 avoids manual identification of whether the orientation of the base 1 placed on the belt is correct, thereby improving the conveying efficiency. With the help of the side wall of the conveying platform 41 and the base 1 downstream of the conveying, the base 1 that needs to be aligned is positioned, making full use of existing components and simplifying the structure.

[0093] Further, such as Figure 2 As shown, the second alignment member 432 is a rod-shaped structure, and the alignment component 43 further includes a support member 434, one end of which is connected to the second side wall, and the other end is connected to the second alignment member 432. As the belt transmits the base 1, the first part of the base 1 is located between the first side wall and the second alignment member 432, and the studs 11 of the base 1 are all abutted against one side of the second alignment member 432. The base 1 that needs to be aligned can also rotate around the intersection of the studs 11 and the rod-shaped structure, and a force toward the second side wall is applied to the rod-shaped structure. The setting of the support member 434 applies a force toward the first side wall to the rod-shaped structure, and in this way, the second alignment member 432 is prevented from being squeezed by the base 1 in the direction close to the second side wall, causing the second alignment member 432 to lose its alignment function.

[0094] In some other optional embodiments, the second aligning member 432 is a planar structure, one side of the planar structure is connected to the second side wall, and the other side of the planar structure is used to abut against the stud 11.

[0095] In some optional embodiments, the unloading mechanism 6 includes a paddle, which is rotated to unload the assembled base 1 and nut 2. It can be seen that the unloading mechanism is simple in composition, and the unloading method is simple and fast, thus reducing the cost of assembly tooling and the occupied area.

[0096] In some optional embodiments, a limiter 321 is provided on the working groove 32 to prevent the telescopic assembly 7 from lifting the base 1 when extending, so that it is separated from the working groove 32. In this way, the base 1 is always located in the working groove 32, which facilitates the smooth assembly work.

[0097] In some optional embodiments, such as Figure 1 and Fig. 9As shown, a preparatory station G is provided between the base loading station A and the nut loading station B. The preparatory station G is used to make the telescopic assembly 7 perform telescopic conversion to prevent the telescopic assembly from suddenly changing, thereby improving the service life of the telescopic assembly; an assembly station H is provided between the nut loading station B and the unloading station C. The assembly station H is used to assemble the base 1 and the nut 2. When located at the assembly station H, the first pin 712 extends into the base 1 and positions the base 1. The top end of the second pin 721 is located in the first pin 712, so that the nut 2 can be assembled on the stud 11. That is, when the turntable 31 rotates, each working slot 32 can be switched in turn between the base loading station A, the preparatory station G, the nut loading station B, the assembly station H and the unloading station C. In this way, a complete assembly process is formed to realize the assembly of the base 1 and the nut 2, reduce labor costs, and improve assembly efficiency.

[0098] In some examples, the nut 2 includes a first part having an external texture and a second part located at the bottom of the first part. The inner diameter of the first part is larger, and the inner diameter of the second part is smaller. In actual engineering, the first part is screwed on the outside of the stud 11, and the second pin 721 can extend out of the nut 2, thereby improving the grasping efficiency of the nut 2 and preventing the nut 2 from detaching from the base 1 when the turntable 312 drives the nut to rotate.

[0099] In some optional embodiments, the nut feeding mechanism 5 includes a vibrating member that drives the nut box 51 to vibrate, so that the nuts 2 enter the nut conveying track 52 under the action of the vibration force and are conveyed by the nut conveying track 52. The nuts 2 exist in various states in the nut box 51, such as Figure 4 As shown, for example, vertical, horizontal, inclined, etc., since the opening of the nut box 51 allows the nut 2 in a vertical state to pass through, the nut 2 passing through the opening is vibrated to a vertical state through the vibration of the vibration box and enters the nut conveying track 52. In this way, the conveying efficiency of the nut 2 is improved.
