[0077] In order to more clearly understand the purpose, features and advantages of the present application, the present application is described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features in the embodiments can be combined with each other. In the following description, many specific details are set forth to facilitate a full understanding of the present application, and the embodiments described are only a part of the embodiments of the present application, rather than all of the embodiments.

[0078] The embodiments of the present application are further described below in conjunction with the accompanying drawings.

[0079] See also Figure 1 , the present application embodiment provides a positioning device 100, which is used to position the second workpiece 300 to a preset position of the first workpiece 200. Figure 1 and Figure 2 The positioning device 100 includes a base 10, a driving assembly 20 connected to the base 10, a reference assembly 30 movably arranged on the base 10, a sliding assembly 40 movably arranged in the reference assembly 30 and engaged with the driving assembly 20, and a positioning assembly 50 slidably connected to the reference assembly 30. The first workpiece 200 is a straight-line product, such as a long frame of a mobile phone frame, and the second workpiece 300 is a BOSS column. It can be understood that Figure 1 A Cartesian three-dimensional coordinate system is established in the first direction. Figure 1 The X-axis direction shown is the width direction of the base 10, and the second direction is Figure 1 The Y-axis direction shown is the length direction of the base 10, and the third direction is Figure 1 The Z-axis direction shown is the direction in which the base 10 points to the reference assembly 30 .

[0080] See also Figure 3The base 10 includes a body 11 and a positioning body 12 connected to the body 11. The body 11 is generally plate-shaped, connected to the driving assembly 20 and carrying the reference assembly 30, and the body 11 is provided with a guide groove 111, which runs through the opposite sides of the body 11. The positioning body 12 is generally rod-shaped, and the number of the positioning bodies 12 is two. The two positioning bodies 12 are arranged on the opposite sides of the body 11 along the second direction and are respectively adjacent to the reference assembly 30, and the two positioning bodies 12 position the reference assembly 30 to the body 11.

[0081] In this way, by setting the above-mentioned positioning body 12, the reference component 30 set on the main body 11 can be positioned, so that the driving component 20 is stably engaged with the sliding component 40 accommodated in the reference component 30, which facilitates the driving component 20 to stably drive the sliding component 40 engaged with the driving component 20 to move.

[0082] The base 10 is also provided with a plurality of positioning stations 13, and the plurality of positioning stations 13 are arranged in sequence at intervals. The positioning device 100 includes a plurality of groups of drive components 20, a plurality of groups of reference components 30, a plurality of groups of sliding components 40 and a plurality of groups of positioning components 50. Each positioning station 13 is arranged in a one-to-one correspondence with each drive component 20, each reference component 30, each sliding component 40 and each positioning component 50. Each drive component 20 is respectively located at a corresponding positioning station 13 and connected to the base 10. Each reference component 30 and the corresponding drive component 20 are respectively located on opposite sides of the base 10 and at the corresponding positioning station 13, and each reference component 30 is movably arranged on the base 10. Each sliding component 40 is movably arranged in the corresponding reference component 30, and each positioning component 50 is respectively slidably connected to the corresponding reference component 30.

[0083] By arranging each positioning station 13 in one-to-one correspondence with each driving component 20, each reference component 30, each sliding component 40 and each positioning component 50, the positioning device 100 can simultaneously perform positioning operations on multiple first workpieces 200 and multiple second workpieces 300 adapted thereto, thereby improving positioning efficiency.

[0084] See also Figure 4The driving assembly 20 includes a driving member 21 connected to the base 10, a rotating member 22 connected to the driving member 21, and a linkage member 23 connected to the rotating member 22. The driving member 21 is connected to the side of the base 10 away from the reference assembly 30. The rotating member 22 is roughly in the shape of a ∘, and the rotating member 22 is rotatably connected to the base 10, and the two ends of the rotating member 22 are respectively connected to the driving member 21 and the linkage member 23. The rotating member 22 rotates under the drive of the driving member 21 and drives the linkage member 23 to move along the first direction. The linkage member 23 is roughly in the shape of a block, and the linkage member 23 is movably arranged in the guide groove 111 and is clamped with the sliding assembly 40. The linkage member 23 drives the sliding assembly 40 to move along the first direction under the guidance of the guide groove 111. Specifically, the rotating member 22 includes a first rotating portion 221, a second rotating portion 222 rotatably connected to the first rotating portion 221, and a third rotating portion 223 rotatably connected to the second rotating portion 222. The first rotating portion 221 is generally in the shape of an elongated strip. The first rotating portion 221 is disposed along the second direction on the side of the base 10 away from the pedestal 31. One end of the first rotating portion 221 is rotatably connected to the base 10, and the other end of the first rotating portion 221 is connected to the driving member 21. The second rotating portion 222 is generally in the shape of an elongated strip. The second rotating portion 222 is disposed along the first direction and is located on the same side as the first rotating portion 221. One end of the second rotating portion 222 is rotatably connected to the end of the first rotating portion 221 away from the driving member 21, and the other end of the second rotating portion 222 is rotatably connected to the base 10. The third rotating portion 223 is generally in the shape of an elongated strip. The third rotating portion 223 is disposed parallel to the first rotating portion 221 along the first direction. One end of the third rotating portion 223 is rotatably connected to the end of the second rotating portion 222 away from the first rotating portion 221, and the other end of the third rotating portion 223 is rotatably connected to the linkage member 23. The first rotating portion 221, the second rotating portion 222 and the third rotating portion 223 constitute a force-saving lever structure.

[0085] In this embodiment, the driving member 21 is a cylinder, which provides a relatively small driving force, which makes it difficult to drive the linkage member 23 to drive the sliding component 40 to move. In this way, by setting the above-mentioned rotating member 22, the rotating member 22 can form a force-saving lever structure, so that the rotating member 22 adjusts the driving force of the driving member 21 to the preset driving force, so that the rotating member 22 can stably drive the sliding component 40 to move through the linkage member 23.

[0086] See also Figure 1The positioning device 100 further includes two groups of clamping assemblies 60 connected to the base 10. The two clamping assemblies 60 are symmetrically arranged on the base 10 along the second direction and are respectively connected to the base 10. The two groups of clamping assemblies 60 are respectively abutted against the two sides of the reference assembly 30 to clamp the reference assembly 30 to the base 10. In this embodiment, each group of clamping assemblies 60 includes a clamping drive member 61 and a clamping member 62. The clamping drive member 61 is arranged on the base 10. The clamping member 62 is roughly plate-shaped. The clamping member 62 is connected to the clamping drive member 61. The clamping drive member 61 can be a cylinder.

[0087] In this way, by setting the above-mentioned two groups of clamping components 60, when the reference component 30 is placed on the base 10, the two clamping driving components 61 respectively drive the two clamping components 62 to move relative to each other, so that the two clamping components 62 are both in contact with the two sides of the reference component 30 to press the reference component 30 to the base 10, thereby preventing the reference component 30 from shaking due to interference from the driving component 20 during operation, which is conducive to the positioning component 50 to smoothly perform the positioning operation.

[0088] See also Figure 2 and Figure 5 The reference assembly 30 includes a base 31 movably disposed on the base 10, a first reference member 32 connected to the base 31, a second reference member 33 spaced apart from the first reference member 32 and connected to the base 31, and a third reference member 34 connected to the base 31. The base 31 is movably disposed on the body 11 and is engaged with the positioning body 12. The base 31 carries the first workpiece 200 and the second workpiece 300. The base 31 is provided with a side facing the base 10 such as a receiving linkage member 23. Figure 6 The avoidance groove 3121 shown, the linkage member 23 passes through the avoidance groove 3121 and is engaged with the sliding assembly 40 movably provided on the base 31. The first reference member 32 is roughly block-shaped, the first reference member 32 is connected to the base 31, and the first reference member 32 positions the first workpiece 200 along the first direction. The second reference member 33 is roughly block-shaped, the second reference member 33 and the first reference member 32 are arranged on one side of the first reference member 32 along the second direction and are connected to the base 31, and the second reference member 33 positions the second workpiece 300 along the first direction. The third reference member 34 is roughly rectangular, the third reference member 34 and the second reference member 33 are located on opposite sides of the first reference member 32 along the second direction, and one end of the third reference member 34 is connected to the first reference member 32, and the third reference member 34 positions the second workpiece 300 to the first workpiece 200 along the second direction.

[0089] In this way, by setting the specific structure of the above-mentioned reference assembly 30, when the sliding assembly 40 drives the positioning assembly 50 to move close to the first reference member 32, the second reference member 33 and the third reference member 34 in the reference assembly 30, the three reference members can cooperate with each other to abut against different positions of the first workpiece 200 and the second workpiece 300 respectively, so as to position the second workpiece 300 to the preset position of the first workpiece 200.

[0090] In this embodiment, a plurality of second workpieces 300 are simultaneously positioned to different positions of the first workpiece 200, and a plurality of second reference members 33 are provided in the reference assembly 30, and the plurality of second reference members 33 are sequentially arranged at intervals along the first direction and are respectively connected to the base 31. In this way, by providing a plurality of second reference members 33, the reference assembly 30 can simultaneously position a plurality of second workpieces 300 to different preset positions of the first workpiece 200, without positioning a plurality of second workpieces 300 to the first workpiece 200 one by one, thereby improving the positioning efficiency.

[0091] The reference assembly 30 also includes four clamping members 35, each of which is roughly hook-shaped. The four clamping members 35 are divided into two groups. The two groups of clamping members 35 are respectively arranged on both sides of the base 31 along the first direction. Each group of two clamping members 35 are arranged in sequence and spaced apart in the first direction. The first reference member 32, the second reference member 33 and the third reference member 34 are located between the four clamping members 35.

[0092] See also Figure 5 and Figure 6 The base 31 includes a fixing member 311 connected to the first reference member 32, a connecting member 312 connected to the fixing member 311 and movably arranged on the base 10, and a limiting member 313 connected to the connecting member 312. The fixing member 311 is roughly plate-shaped, and the fixing member 311 is respectively connected to the first reference member 32, the second reference member 33 and the third reference member 34. The connecting member 312 is roughly concave, and the connecting member 312 is movably arranged on the base 10 and connected to the fixing member 311. The connecting member 312 is provided with a avoiding groove 3121 of the avoiding linkage member 23, and an active space 3122 for accommodating the movement of the sliding assembly 40 is formed between the connecting member 312 and the fixing member 311. The limiting member 313 is roughly rod-shaped, and the limiting member 313 is arranged on one side of the connecting member 312 adjacent to the fixing member 311 and movably penetrates the sliding assembly 40 accommodated in the active space 3122. The limiting member 313 is used to limit the movement distance of the sliding assembly 40.

[0093] In this way, by setting the above-mentioned limit member 313 to be movably installed in the sliding component 40, when the sliding component 40 slides in the activity space 3122, the limit member 313 can limit the movement distance of the sliding component 40 to prevent the sliding component 40 from moving too far and leaving the activity space 3122.

[0094] See also Figure 7 The sliding component 40 is roughly plate-shaped. The sliding component 40 is located in the active space 3122 and is movably arranged in the base 31. The sliding component 40 is clamped with the linkage member 23 received in the avoidance groove 3121. The sliding component 40 is provided with a first straight hole 41, a second straight hole 42 and an inclined hole 43. The first straight hole 41 and the second straight hole 42 are staggered along the first direction, and the inclined hole 43 is adjacent to the second straight hole 42. The driving member 21 drives the linkage member 23 to drive the sliding component 40 to move along the first direction.

[0095] In this way, by setting the specific structure of the above-mentioned sliding component 40, when the reference component 30 is placed on the base 10, the linkage member 23 passes through the avoidance groove 3121 and is engaged with the sliding component 40, so that the driving member 21 drives the sliding component 40 engaged with the linkage member 23 to move along the first direction through the linkage member 23, thereby realizing the function of the sliding component 40 moving along the first direction.

[0096] The sliding assembly 40 is provided with a limiting groove 44 , which passes through two opposite sides of the sliding assembly 40 . The cross-sectional area of ​​the limiting groove 44 is larger than the cross-sectional area of ​​the limiting member 313 , and the limiting groove 44 receives the limiting member 313 .

[0097] In this way, by setting the above-mentioned limit groove 44, the limit groove 44 can accommodate the limit member 313. When the sliding component 40 moves a preset distance under the drive of the linkage member 23, the groove wall of the limit groove 44 abuts against the limit member 313 to limit the movement distance of the sliding component 40, thereby preventing the sliding component 40 from moving too far and leaving the activity space 3122.

[0098] See also Figure 5 and Figure 8 The positioning assembly 50 includes a first positioning member 51 slidably connected to the base 31 , a second positioning member 52 corresponding to the second reference member 33 and slidably connected to the base 31 , and a third positioning member 53 corresponding to the third reference member 34 and slidably connected to the base 31 . The first positioning member 51 is arranged opposite to the first reference member 32 and includes a first shaft 511 inserted into the first straight hole 41, the first shaft 511 is roughly rod-shaped, and the first positioning member 51 positions the first workpiece 200 to the first reference member 32 under the drive of the sliding component 40. The second positioning member 52 is arranged opposite to the second reference member 33 and includes a second shaft 521 inserted into the second straight hole 42, the second shaft 521 is roughly rod-shaped, and the second positioning member 52 positions the second workpiece 300 to the second reference member 33 under the drive of the sliding component 40. The third positioning member 53 is arranged opposite to the third reference member 34 and includes a third shaft 531 inserted into the inclined hole 43, the third shaft 531 is roughly rod-shaped, and the third positioning member 53 positions the second workpiece 300 to the first workpiece 200 under the drive of the sliding component 40 and pushes the first workpiece 200 to be positioned to the third reference member 34.

[0099] In this way, by setting the specific structure of the above-mentioned positioning assembly 50, when the sliding assembly 40 moves along the first direction under the drive of the linkage member 23, each positioning member moves toward the corresponding reference member respectively under the cooperation of the corresponding axis and the corresponding hole, thereby realizing the function of the positioning assembly 50 to position the second workpiece 300 to the preset position of the first workpiece 200.

[0100] It can be understood that when the first workpiece 200 and the second workpiece 300 are arranged on the base 31, the distance between the first positioning member 51 and the first workpiece 200 along the first direction is a first preset distance, the distance between the second positioning member 52 and the second workpiece 300 along the first direction is a second preset distance, and the distance between the third positioning member 53 and the second workpiece 300 along the second direction is a third preset distance. The first preset spacing, the second preset spacing and the third preset spacing increase in sequence. In this way, when the positioning assembly 50 positions the second workpiece 300 to the preset position of the first workpiece 200, the first positioning member 51 first positions the first workpiece 200 to the first reference member 32 along the first direction, and then the second positioning member 52 positions the second workpiece 300 to the second reference member 33 along the first direction. Finally, the third positioning member 53 pushes the first workpiece 200 to the third reference member 34 through the second workpiece 300 along the second direction, so as to position the second workpiece 300 to the preset position of the first workpiece 200 along the second direction, so that the first positioning member 51, the second positioning member 52 and the third positioning member 53 complete the positioning operation in sequence, and avoid the poor synchronization of the positioning members when the three positioning members move synchronously to position the second workpiece 300 on the first workpiece 200, which causes a position offset between the first workpiece 200 and the second workpiece 300, thereby improving the positioning accuracy.

[0101] In this embodiment, there are multiple second positioning members 52, and the multiple second positioning members 52 are sequentially arranged at intervals along the first direction and are respectively arranged one-to-one with the multiple second reference members 33. In this way, by arranging multiple second positioning members 52 and respectively corresponding to the multiple second reference members 33, the positioning device 100 can simultaneously position multiple second workpieces 300 to different preset positions of the first workpiece 200.

[0102] See also Figure 8The first positioning member 51 includes a positioning portion 512 slidably connected to the base 31, and a first elastic portion 513 abutting against the positioning portion 512. The positioning portion 512 is generally block-shaped, and the positioning portion 512 is arranged opposite to the first reference member 32 and slidably connected to the base 31. The positioning portion 512 is connected to the first shaft 511 on the side facing the base 31, and the first shaft 511 and the first straight hole 41 cooperate to drive the positioning portion 512 to move close to the first reference member 32.

In this embodiment, there are multiple first pressure members 72 and second pressure members 73, and the multiple first pressure members 72 are arranged in sequence and at intervals along the first direction and connected to the cover member 71. The multiple second pressure members 73 are staggered with the multiple first pressure members 72 along the second direction, and the multiple second pressure members 73 are arranged in sequence and at intervals on the cover member 71 along the first direction and are arranged one by one with the multiple second workpieces 300.

[0111] In the present embodiment, the second pressing member 73 is similar to the first pressing member 72 in that it also includes a pressing portion 721 and a second elastic portion 722.

In this way, by setting the above-mentioned locking member 74 and the clamping member 35 to cooperate with each other, it is possible to lock the cover member 71 to the base 31, so that the first pressing member 72 and the second pressing member 73 can stably press the corresponding first workpiece 200 and the second workpiece 300 to the base 31.

[0114] The working process of the positioning device 100 is roughly as follows:

[0115] First, the robot or operator places the base 31 on the body 11, and the positioning body 12 positions the base 31 on the body 11, so that the linkage member 23 passes through the avoidance groove 3121 and is accurately engaged with the sliding assembly 40, and then the robot or operator places the first workpiece 200 and the second workpiece 300 on the base 31;

[0116] Then, the driving member 21 drives the linkage member 23 to drive the sliding assembly 40 engaged with the linkage member 23 to move in the first direction, and the sliding assembly 40 drives the first axis 511, the second axis 521 and the third axis 531 to move close to the corresponding reference member through the first straight hole 41, the second straight hole 42 and the inclined hole 43, so that the first positioning member 51, the second positioning member 52 and the third positioning member 53 successively position the first workpiece 200 and the second workpiece 300 to the corresponding reference member, so as to position the second workpiece 300 to the preset position of the first workpiece 200, realize the mechanized positioning operation, and improve the positioning efficiency and positioning accuracy;

[0117] Finally, the locking member 74 moves along the first direction to connect the receiving groove 741 with the avoidance groove 711, and then the cover member 71 is moved to the base 31, and the connected receiving groove 741 and the avoidance groove 711 avoid the clamping member 35, and then the locking member 74 is reset to the initial position, so that the receiving groove 741 and the avoidance groove 711 are misaligned, and the clamping member 35 abuts against the upper surface of the locking member 74 and is mutually clamped with the locking member 74, so that the clamping member 35 and the locking member 74 cooperate to lock the cover member 71 to the base 31, so that the first pressing member 72 and the second pressing member 73 respectively press the first workpiece 200 and the second workpiece 300 to the base 31 along the third direction, so as to facilitate the subsequent process operations of the first workpiece 200 and the second workpiece 300.
