DETAILED DESCRIPTION

[0036] The present application will be further described below in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the present application and implement it. The embodiments are not intended to limit the present application.

[0037] Referring to Figure 1 , Figure 2 and Figure 3 , the present application discloses a locking and positioning device for positioning products on a carrier 10. Preferably, the carrier 10 comprises oppositely arranged first surface 11 and second surface 12, and the first surface 11 is provided with positioning holes 13 extending to the second surface 12; the products comprise first component 111 and second component 112 which need to be screwed and locked. The locking and positioning device comprises a positioning seat 20 and a locking piece 30.

[0038] The positioning seat 20 is used to mount components and contact the first surface 11 of the carrier 10 to realize the positioning of the products on the carrier 10. The positioning seat 20 is provided with a positioning and pressing component 21 to press the first component 111 and the second component 112 which are stacked together and not screwed and locked. Preferably, the positioning and pressing component 21 contacting the surface of the second component 112 is provided with a flexible part 211 such as rubber, so as to better position the products and prevent the products from being damaged.

[0039] The locking piece 30 is used to contact the second surface 12 of the carrier 10 to cooperate with the positioning seat 20 to realize the positioning of the products on the carrier 10. Specifically, the locking piece 30 comprises a guide piece 31 and a locking component 32. The guide piece 31 is movably connected to the positioning seat 20 and is configured to be able to switch between a first position and a second position relative to the positioning seat 20. Preferably, the positioning seat 20 is provided with a linear bearing, and the guide piece 31 can axially move through the linear bearing to realize the switching between the first position and the second position.

[0040] When the guide 31 is located at the first position and the second position and does not contact the carrier 10, the locking part 32 can rotate relative to the guide 31 between the first angle and the second angle. When the locking part 32 is located at the first angle, the locking part 32 prevents the locking piece 30 from exiting the positioning hole 13. When the locking part 32 is located at the second angle, the locking piece 30 can extend into or exit the positioning hole 13. When the guide 31 is located at the second position and penetrates the positioning hole 13, the locking part 32 maintains the first angle, and the locking part 32 abuts against the second face 12 of the carrier 10 and the positioning seat 20 abuts against the first face 11 of the carrier 10, so that the positioning and pressing part 21 positions the product. By arranging the structure, the two stations for assembling and locking screws for the product can be arranged, the time of the entire assembly process is reduced, the production efficiency is improved, the relative position between the two parts is prevented from deviating, the high position precision is ensured, and the product quality is guaranteed. Preferably, the guide 31 is in clearance fit with the positioning hole 13.

[0041] In actual use, the first part 111 is arranged on the first face 11 of the carrier 10, the second part 112 is placed on the first part 111, and then the locking piece 30 penetrates the positioning hole 13 of the carrier 10. After the assembly is completed, the angle of the locking part 32 is adjusted to the first angle, and the locking piece 30 is adjusted to the first position. At this time, the positioning seat 20 abuts against the first face 11 of the carrier 10, the locking part 32 abuts against the second face 12 of the carrier 10, and the positioning and pressing part 21 presses the positioned product, so that the relative displacement of the first part 111 and the second part 112 is prevented and the high position precision of the two parts is ensured. Then, the first part 111 and the second part 112 are screwed and locked. After the locking is completed, the locking piece 30 is adjusted to the second position, and the angle of the locking part 32 is adjusted to the second angle, so that the locking and positioning device is separated from the carrier 10.

[0042] The locking and positioning device disclosed by the application positions and presses the product on the carrier 10 by arranging the positioning seat 20 and the locking piece 30 to cooperate with the carrier 10, so that the assembly of the product is realized. The first part 111 and the second part 112 of the product can be assembled in two stations, the production efficiency is improved, and the demand for yield is met. At the same time, the positioning during the assembly of the product can be effectively realized, the position precision of the parts is high, the high product quality is effectively ensured, and the defective rate is reduced.

[0043] Reference Figure 4 and Figure 5As shown, the locking positioning device provided by the present application is provided with a receiving space 311 on the guide member 31 in some embodiments; preferably, the receiving space 311 is provided on the axial end of the guide member 31. At least part of the locking member 32 is arranged in the receiving space 311 and is rotationally connected to the guide member 31; preferably, the locking member 32 is provided with a hole, and the receiving space 311 of the guide member 31 is provided with a rotating shaft 36 matched with the hole, and the locking member 32 is rotationally connected to the rotating shaft 36 to realize the switching of the first angle and the second angle. The locking member 32 is provided with an abutting portion 321 to realize the abutting to the second surface 12 of the carrier 10. Preferably, the abutting portion 321 is provided in a triangular prism structure to improve the space utilization under the premise of abutting to the carrier 10 at the first angle and preventing the locking member 30 from exiting the positioning hole 13, and the locking member 32 can be fully retracted into the receiving space 311 at a smaller angle, so that the locking member 30 can exit the positioning hole 13 of the carrier 10. In addition, the triangular prism structure of the abutting portion 321 can also improve the production efficiency. Specifically, when the locking member 30 is separated from the carrier 10 and needs to be connected, the locking member 32 at the first angle can be quickly rotated to the second angle and retracted into the receiving space 311 when it contacts the carrier 10, thereby quickly realizing assembly and improving production efficiency.

[0044] One of the locking member 32 and the guide member 31 is provided with an arc-shaped groove 322, and the other is provided with a limiting portion 312, and the arc-shaped groove 322 extends along the circumferential direction of the rotating shaft 36 of the locking member 32. Preferably, the arc-shaped groove 322 is provided on the locking member 32, the limiting portion 312 is provided as a limiting pin, and is arranged on the guide member 31 for assembly. The arc-shaped groove 322 includes a first end 3221 corresponding to the first angle and a second end 3222 corresponding to the second angle, and the limiting portion 312 is slidingly connected to the arc-shaped groove 322. That is, when the first end 3221 of the arc-shaped groove 322 coincides with the axis of the guide member 31, the locking member 32 is at the first angle; when the second end 3222 of the arc-shaped groove 322 coincides with the axis of the guide member 31, the locking member 32 is at the second angle. By arranging the structure, not only the switching of the angle can be realized to realize the locking and unlocking actions, but also the limiting effect can be achieved to limit the rotating angle of the locking member 32 within a suitable range, so that the locking member 32 can rotate more smoothly, improve the production efficiency, and enhance the structural stability and reliability. In actual use, when the limiting portion 312 is located at the first end 3221, the abutting portion 321 extends out of the receiving space 311; when the locking member 30 is located in the positioning hole 13, the extended abutting portion 321 can cooperate with the positioning seat 20 and abut against the carrier 10 to realize the positioning of the product by the positioning and pressing member 21. When the limiting portion 312 is located at the second end 3222, the locking member 32 is retracted into the receiving space 311, so that the locking member 30 can extend into or exit the positioning hole 13 of the carrier 10.

[0045] The locking member 30 further comprises a first elastic component 33 arranged in the accommodating space 311. The first elastic component 33 is used to provide an elastic force for the locking component 32, so that the locking component 32 has a tendency to move along the extending direction of the arc-shaped groove 322 to the first end 3221. Preferably, the first elastic component 33 is arranged as a torsion spring, which comprises a first abutting end 331 and a second abutting end 332. The first abutting end 331 is used to abut against the inner wall of the accommodating space 311, and the second abutting end 332 is used to abut against the locking component 32. By arranging the first elastic component 33, the locking component 32 can be kept at the first angle without other forces, i.e. the limiting portion 312 is located at the first end 3221 of the arc-shaped groove 322, so that the abutting portion 321 extends out of the accommodating space 311. When the locking member 30 is located in the positioning hole 13, this structure can better realize the abutting and locking action on the carrier 10, so as to avoid accidental unlocking and the like. Preferably, a limiting shaft 314 is arranged in the accommodating space 311, and the torsion spring is sleeved on the limiting shaft 314.

[0046] Further, referring to Fig. 2, Figure 6 In some embodiments, the locking member 30 further comprises a limiting portion 312 arranged on the side of the locking component 32 away from the abutting portion 321. The limiting portion 312 is arranged to abut against the inner wall of the accommodating space 311. By arranging the limiting portion 312, the locking component 32 can be kept at the first angle without other forces, i.e. the limiting portion 312 is located at the first end 3221 of the arc-shaped groove 322, so that the abutting portion 321 extends out of the accommodating space 311. When the locking member 30 is located in the positioning hole 13, this structure can better realize the abutting and locking action on the carrier 10, so as to avoid accidental unlocking and the like. Preferably, the limiting portion 312 is arranged as a limiting protrusion.

[0047] Further, referring to Fig. 2, Figure 7As shown, in some embodiments, the locking positioning device provided by the present application is provided with two locking components 32, and the abutting portions 321 of the two locking components 32 are respectively located on the two radial sides of the guide 31. Compared with the case of providing only one locking component 32 or more locking components 32, by providing two locking components 32, the locking component 30 can form an arrow-like structure when the locking component 32 maintains the first angle, so as to abut against the carrier 10 through the two abutting portions 321 of the two locking components 32, improve the reliability and stability of the locking, and take into account the simple structure and convenient production and assembly.

[0048] Further, referring to Figure 8 As shown, in some embodiments, when the limiting portion 312 is located at the first end 3221, the distance H1 from the edge of the abutting portion 321 to the axis of the guide 31 and the radial dimension H2 of the guide 31 satisfy the relationship H1=k*H2, k∈[1.2, 1.5]. The person skilled in the art can set the specific value of k according to the actual needs, for example, 1.2, 1.25, 1.3, 1.35, 1.4, 1.45, 1.5, etc. Preferably, taking the radial dimension H2 of the guide 31 as 3.8mm, the distance H1 from the edge of the abutting portion 321 to the axis of the guide 31 can be set as 4.8 or 5.5mm. When the value of k is less than 1.2, the relative size of the abutting portion 321 is too small, and it is difficult to effectively realize the locking of the carrier 10, and the reliability is low. When the value of k is greater than 1.5, although the abutting portion 321 can effectively realize the locking of the carrier 10, the relative size is too large, the space utilization rate is low, and it is easy to increase the volume or cause interference problems with other components during the rotation of the locking component 32. When k is located between 1.2 and 1.5, the good space utilization rate and reliability can be taken into account, and the locking component 30 can effectively realize the locking of the carrier 10 under the premise of small volume.

[0049] Preferably, the length of the first abutting end 331 of the torsion spring is set to 2.5-4 mm, when it is less than 2.5 mm, the torsion spring is at risk of failure; when it is greater than 4 mm, the torsion spring is easy to extend out of the accommodation space 311 and interfere with other components. When the length of the first abutting end 331 is set to 2.5-4 mm, the elastic force can be stably provided, and the interference problem is not easy to occur. The length of the first abutting end 331 of the torsion spring is set to 3.6-5.6 mm, when it is less than 3.6 mm, the torsion spring is at risk of failure; when it is greater than 5.6 mm, the torsion spring is easy to extend out of the accommodation space 311 and interfere with other components. When the length of the second abutting end 332 is set to 3.6-5.6 mm, the elastic force can be stably provided, and the interference problem is not easy to occur. Preferably, the first end 3221 and the second end 3222 of the arc-shaped groove 322 are 18.5°-19.5° compared to the central angle α1 of the rotating shaft 36, when it exceeds the range, the locking component 32 runs smoothly, and affects the locking of the product; preferably, it is set to 19°.

[0050] Referring to Figure 8 The locking positioning device described in the present application is provided with two locking members 30 in some embodiments, and the guide members 31 of the two locking members 30 are connected to the connecting members 34 at the end away from the locking component 32. Through the arrangement of the structure, the positioning failure caused by the rotation problem can be effectively prevented; preferably, the positioning and pressing component 21 is arranged at the middle position of the positioning seat 20 between the two guide members 31. In the actual use process, the control action for the two locking members 30 can also be synchronously realized through the connecting member 34.

[0051] In some embodiments, the locking member 30 is provided with only one, and the positioning seat 20 is provided with a positioning component for preventing the positioning and pressing component 21 from rotating relative to the carrier 10, and the structure can also prevent the positioning failure caused by the rotation problem. The positioning component is not shown in the figure; preferably, the positioning component is set to a pin, and the carrier 10 is provided with a hole corresponding to the positioning component.

[0052] Further, referring to Figure 8As shown, the locking positioning device of the present application, in some embodiments, the locking member 30 further comprises a second elastic component 35, which is used to provide an elastic force for the guide member 31, so that the guide member 31 has a tendency to move to the second position. Preferably, the second elastic component 35 is provided as a spring. Taking the structure provided with two locking members 30 and a connecting member 34 as an example, the second elastic component 35 is sleeved on the guide member 31, and one end thereof abuts against the connecting member 34, and the other end thereof abuts against the positioning seat 20. In use, the connecting member 34 is pressed to overcome the elastic force of the second elastic component 35, so that the relative position of the guide member 31 and the positioning seat 20 is changed, and the locking member 30 extends into the positioning hole 13 of the carrier 10. Subsequently, the action of the connecting member 34 is removed, and under the elastic force of the second elastic component 35, the guide member 31 moves to the second position, and the locking member 32 and the positioning seat 20 abut against the carrier 10 to realize positioning of the product through the positioning and pressing member 21.

[0053] Referring to Figure 9 As shown, the present application discloses an unlocking device for unlocking the locking positioning device as described in any one of the above embodiments. The unlocking device comprises an unlocking member 40, which is provided with a first open cavity 41, and when the guide member 31 is located at the first position and is sleeved in the first open cavity 41, the cavity wall of the first open cavity 41 abuts against the locking member 32, so that the locking member 32 maintains the second angle. Preferably, the first open cavity 41 is in clearance fit with the guide member 31. Through the arrangement of the structure, efficient unlocking can be realized to improve the production efficiency; and the device structure is simple, small in size, and high in space utilization.

[0054] Specifically, in use, the unlocking member 40 is arranged on the second side 12 of the carrier 10. The connecting member 34 is pressed to overcome the elastic force of the second elastic component 35, so that the relative position of the guide member 31 and the positioning seat 20 is changed, and the guide member 31 extends into the first open cavity 41. In the process of extending, the abutting portion 321 of the locking member 32 is separated from the second side 12 of the carrier 10, and is subjected to the force of the cavity wall of the first open cavity 41, so as to rotate and retract into the accommodating space 311 of the guide member 31. Subsequently, the action of the connecting member 34 is removed, so that the locking member 30 sequentially exits the first open cavity 41 and the positioning hole 13 under the elastic force of the second elastic component 35, so as to separate the locking positioning device and the carrier 10.

[0055] Referring to Figure 9 and Figure 10As shown, the unlocking device of the present application further comprises an unlocking seat 50 and a third elastic component 511 in some embodiments. The unlocking seat 50 is provided with a second opening cavity 51, at least part of the unlocking component 40 is movably arranged in the second opening cavity 51, and the opening directions of the first opening cavity 41 and the second opening cavity 51 are the same. The third elastic component 511 is arranged in the second opening cavity 51, and the third elastic component 511 is used to provide an elastic force for the unlocking component 40, so that the unlocking component 40 has a tendency to extend out of the second opening cavity 51. Preferably, at least part of the unlocking component 40 extends out of the second opening cavity 51 without other forces.

[0056] By setting this structure, the floating and avoiding actions of the unlocking component 40 can be realized to prevent the unlocking component 40 from being damaged by hard contact with the locking part 30, thereby prolonging the service life of the device. When the locking part 30 exits the first opening cavity 41, this floating structure can also prevent the locking part 32 from being rotated in advance to open, thereby ensuring smooth unlocking and improving production efficiency. Preferably, the unlocking device further comprises an unlocking driving part 52 to realize the action of the unlocking seat 50 relative to the locking positioning device. Preferably, the unlocking driving part 52 is set as a pneumatic sliding table.

[0057] In use, after the carrier 10 and the locking positioning device are in place, the unlocking driving part 52 drives the unlocking seat 50 to move relative to the carrier 10, so that the unlocking component 40 contacts the locking part 30. The unlocking component 40 is subjected to the force of the locking part 30 to overcome the force of the third elastic component 511, so as to float and avoid the locking part 30 within a certain range and avoid hard contact. Subsequently, the guide part 31 extends into the first opening cavity 41, exits the first opening cavity 41, and exits the positioning hole 13 in sequence, so as to realize unlocking. After unlocking is completed, the unlocking driving part 52 drives the unlocking seat 50 to move away from the carrier 10, so as to wait for the next unlocking.

[0058] The present application discloses an assembly method for assembling a product, the product comprising a first component 111 and a second component 112. The assembly method comprises the following steps:

[0059] S1, moving the carrier 10 carrying the first component 111 into a first station; wherein the carrier 10 is provided with a through positioning hole 13;

[0060] S2, placing the second component 112 on the first component 111;

[0061] S3, positioning the first component 111 and the second component 112 on the carrier 10 by the locking positioning device as described in any one of the above embodiments;

[0062] S4, moving the carrier 10 into a second station;

[0063] S5, fixedly connecting the first component 111 and the second component 112;

[0064] S6, unlocking the locking positioning device through the unlocking device in any one of the above embodiments;

[0065] S7, separating the locking positioning device and the carrier 10.

[0066] Working principle:

[0067] Taking the streamline operation as an example, the first station and the second station are respectively arranged, and the streamline is used to connect the two stations. The carrier 10 carrying the first component 111 flows into the first station, and the second component 112 is placed on the first component 111 through the mechanical arm. Subsequently, the locking positioning device is positioned on the product through the mechanical arm.

[0068] Specifically, the guide piece 31 is aligned with the positioning hole 13 and the locking positioning device is placed on the carrier 10, and the connecting piece 34 is applied with a force to overcome the elastic force of the second elastic component 35. The positions of the guide piece 31 and the positioning seat 20 are changed, and the guide piece 31 is inserted into the positioning hole 13 of the carrier 10. During the insertion process, the locking component 32 is first subjected to the force of the positioning hole 13 and overcomes the elastic force of the first elastic component 33 and is retracted into the containing space 311; when it extends out of the positioning hole 13, the locking component 32 is affected by the elastic force of the first elastic component 33, and the abutting portion 321 extends out of the containing space 311. After the force on the connecting piece 34 is removed, the second elastic component 35 drives the guide piece 31 to move, so that the abutting portion 321 of the locking component 32 abuts against the second face 12 of the carrier 10, and the positioning seat 20 abuts against the first face 11 of the carrier 10, to realize locking. At this time, the positioning and pressing component 21 presses the first component 111 and the second component 112 to prevent relative movement between them.

[0069] Then, the carrier 10 is transported to the second station through the streamline, and the mechanical arm is used to complete the screwing and fixing connection of the first component 111 and the second component 112. Subsequently, the locking positioning device is unlocked through the unlocking device. Specifically, under the driving of the unlocking driving piece 52, the unlocking seat 50 is relatively close to the carrier 10, so that the unlocking component 40 contacts the locking piece 30. At the time of contact, the unlocking component 40 will be forced to overcome the force of the third elastic component 511 to achieve floating avoidance and avoid hard contact.

[0070] The connecting member 34 is subjected to a force to overcome the elastic force of the second elastic member 35. The position of the guide member 31 and the positioning seat 20 changes, and the guide member 31 is inserted into the first opening cavity 41. In the process of insertion, the abutting portion 321 of the locking member 32 is separated from the second face 12 of the carrier 10, and is subjected to the force of the cavity wall of the first opening cavity 41, so as to rotate and retract into the accommodating space 311 of the guide member 31. After the guide member 31 is inserted into the first opening cavity 41, the unlocking member 40 is floated and reset under the action of the third elastic member 511, so as to prevent the locking member 32 from rotating in advance to open in the process of the locking member 30 exiting. After the force on the connecting member 34 is removed, the guide member 31 is moved by the second elastic member 35, so that the locking member 30 exits the first opening cavity 41 and the positioning hole 13 in turn under the elastic force of the second elastic member 35, and is taken away from the carrier 10 by the mechanical arm.

[0071] Finally, the carrier 10 carrying the assembled product flows into the subsequent work operation, and the subsequent carrier 10 repeats the corresponding operation to realize continuous production.

[0072] Obviously, the above embodiments are only examples for clear illustration, and are not intended to limit the embodiments. Based on the above description, other different forms of changes or variations can be made by those skilled in the art. Here, it is not necessary and impossible to enumerate all the embodiments. The obvious changes or variations derived therefrom are still within the protection scope of the present application.
