[0036] This embodiment discloses a positioning device, referring to Figure 1 and Figure 2 As shown, the positioning device comprises a supporting mechanism 1 , a locking mechanism 2 , a driving mechanism 3 and a vacuum mechanism 4 .

[0037] The bearing mechanism 1 includes a base 11 and a workbench 12, and the workbench 12 is arranged on the base 11. A cavity is arranged inside the base 11, and the workbench 12 is provided with a mounting position 120, a receiving hole 121 and an adsorption hole 122. The mounting position 120 is used to place the part to be positioned 5, and the part to be positioned 5 can be a frame. The receiving hole 121 is arranged on the side of the mounting position 120. There are a plurality of adsorption holes 122, and the plurality of adsorption holes 122 are respectively distributed at intervals along the circumference of the mounting position 120, and the cavity in the base 11 is respectively connected with the plurality of adsorption holes 122.

When the part to be positioned 5 is attached to the glass cover plate, the locking mechanism 2 is driven to move by the driving mechanism 3 so that the locking mechanism 2 releases the part to be positioned 5, and then the part to be positioned 5 is adsorbed and fixed on the workbench 12 by the vacuum mechanism 4, so that the locking mechanism 2 is prevented from colliding with the pressing mechanism when the glass cover plate is attached later, which facilitates the assembly of the part to be positioned 5 and improves the work efficiency.

[0043] Specifically, refer to Figure 2 , Figure 3 and Figure 4 As shown, the locking mechanism 2 includes a mounting seat 21, an oblique slider 22, a stopper 23, a vertical slider 24, a first spring 25 and a second spring 26. The pressing head 20 is arranged on the oblique slider 22, and the oblique slider 22 allows the pressing head 20 to move in the receiving hole 121 under the action of the vertical slider 24.

[0045] Reference Figure 5 and Figure 6As shown, the vertical slider 24 includes two symmetrically arranged columns 24a and a crossbeam 24b connecting the two. The crossbeam 24b is symmetrically provided with first limiting grooves 241 and extends to the inside of the corresponding columns 24a respectively. The first spring 25 is arranged between the first limiting groove 241 and the mounting seat 21, and one end of the first spring 25 abuts against the bottom wall of the first limiting groove 241, and the other end of the first spring 25 is used to abut against the inner wall of the mounting seat 21. The oblique slider 22 includes an oblique portion 22a and an extension portion 22b, the oblique portion 22a and the extension portion 22b intersect at a certain angle, and are staggered at the connection, so as to form a support platform 22c. The support platform 22c is provided with a second limiting groove 221, and the second spring 26 is arranged between the second limiting groove 221 and the limiting member 23, and one end of the second spring 26 abuts against the bottom wall of the second limiting groove 221, and the other end of the second spring 26 is connected to the limiting member 23. The oblique portion 22a is movably disposed in the second mounting cavity 211, and the oblique portion 22a extends along the second direction. One end of the extension portion 22b is connected to the oblique portion 22a, and the other end of the extension portion 22b passes through the mounting seat 21, and the extension portion 22b extends along the first direction to limit the oblique portion 22a when it moves along the second direction, so as to prevent the oblique slider 22 from detaching from the mounting seat 21. The pressure head 20 is disposed at one end of the extension portion 22b passing through the mounting seat 21. The first direction is Figure 4 The middle X direction, the second direction is Figure 4 Center Y direction.

[0046] In this embodiment, the vertical slider 24 is provided with a first limiting groove 241, and the first limiting groove 241 is used to limit the first spring 25 to ensure the stability of the first spring 25 when it is switched between the compressed state and the expanded state. It can be understood that in other embodiments, the first spring 25 can also be limited by other structures. For example, the vertical slider 24 is provided with a protrusion, and the first spring 25 is sleeved on the protrusion so as to limit the first spring 25 by the protrusion.

[0047] In this embodiment, the oblique slider 22 is provided with a second limiting groove 221, and the second limiting groove 221 is used to limit the second spring 26 to ensure the stability of the second spring 26 when it is switched between the compressed state and the expanded state. It can be understood that in other embodiments, the second spring 26 can also be limited by other structures. For example, the oblique slider 22 is provided with a protrusion, and the second spring 26 is sleeved on the protrusion so that the second spring 26 is limited by the protrusion.

[0048] Reference Figure 5 and Figure 6 As shown, a clamping portion 240 is provided on the cross beam 24 b of the vertical slider 24 , and a groove 220 is provided on the oblique portion 22 a . The groove 220 cooperates with the clamping portion 240 to enable the vertical slider 24 to be clamped and connected with the oblique slider 22 .

[0049] During operation, the driving mechanism 3 is used to drive the column 24a to move along the first direction so that the engaging portion 240 on the beam 24b is disengaged from the groove 220. At this time, the elastic force of the second spring 26 causes the inclined portion 22a and the extending portion 22b to move along the second direction so as to hold the part to be positioned 5 through the pressure head 20. The driving mechanism 3 is also used to drive the inclined portion 22a to move along the second direction to release the part to be positioned 5. At this time, the elastic force of the first spring 25 causes the beam 24b to move along the first direction, and the engaging portion 240 engages with the groove 220 on the inclined portion 22a.

[0050] Reference Figure 7 As shown, the driving mechanism 3 includes a first driving assembly 31 and a second driving assembly 32. The first driving assembly 31 includes a first driving member 310, a first movable plate 311 and a plurality of first abutting members 312. The first movable plate 311 is arranged on the base 11 and is located on the side of the workbench 12 facing away from the mounting position 120. The first driving member 310 is arranged on the base 11, and the first driving member 310 is connected to the first movable plate 311. The plurality of first abutting members 312 are respectively connected to the first movable plate 311, and the position and number of each first abutting member 312 are arranged corresponding to the position and number of the vertical slider 24 of each locking mechanism 2. The first driving member 310 is used to drive the first movable plate 311 to move along the first direction, so that each first abutting member 312 respectively pushes the vertical slider 24 of each locking mechanism 2 to move along the first direction.

[0051] The second driving assembly 32 includes a second driving member 320, a second movable plate 321 and a plurality of second abutting members 322. The second movable plate 321 is arranged on the base 11 and is located on the side of the first movable plate 311 facing away from the workbench 12. The first driving member 310 is penetrated through the second movable plate 321, and the second movable plate 321 and the first movable plate 311 are arranged in a stacked manner. The second driving member 320 is arranged on the base 11, and the second driving member 320 is connected to the second movable plate 321. One end of each second abutting member 322 is respectively connected to the second movable plate 321, and the other end of each second abutting member 322 is respectively penetrated through the first movable plate 311, and the position and number of each second abutting member 322 are arranged correspondingly to the position and number of the oblique slider 22 of each locking mechanism 2. The second driving member 320 is used to drive the second movable plate 321 to move along the first direction, so that each second abutting member 322 pushes the oblique slider 22 of each locking mechanism 2 to move along the second direction.

[0052] In a specific application scenario, firstly, double-sided tape is attached to the part to be positioned 5, and then the part to be positioned 5 is adsorbed and fixed to the mounting position 120 by the vacuum mechanism 4, and then the first movable plate 311 is driven to move in the first direction by the first driving member 310, so that each first abutment member 312 respectively pushes each vertical slider 24 to move in the first direction, so that each vertical slider 24 is separated from each oblique slider 22. At this time, each oblique slider 22 respectively moves in the second direction to press the part to be positioned 5 through the pressure head 20. After fixing the part to be positioned 5, tear off the double-sided adhesive film, and then drive the second movable plate 321 to move along the first direction through the second driving member 320, so that each second abutment member 322 pushes each oblique slider 22 to move along the second direction, so that each oblique slider 22 releases the part to be positioned 5. At this time, the vertical slider 24 is moved in the first direction in the direction close to the oblique slider 22 by the elastic force of the second spring 26 to engage with the oblique slider 22. After the oblique slider 22 is moved away, the part to be positioned 5 is attached to the glass cover plate. After bonding, the bonded product is transported to the next process.
