[0001] The utility model relates to the technical field of electronic product screen positioning, in particular to a positioning platform. Background Art

[0002] During the production process of screens for electronic products such as mobile phones and tablets, the flat screens need to be positioned to facilitate processing or testing. Prior art positioning platforms for positioning screens typically include two sets of positioning modules, each consisting of two opposing positioning blocks. The two positioning blocks in one set are arranged perpendicularly to the two positioning blocks in the other set. Within either set of positioning modules, the two positioning blocks can move relative to each other, thereby clamping and positioning the screen.

[0003] As described above, since there is only one positioning block on one side of the screen during the positioning process, when the positioning block contacts the screen, there is only one force point on one side of the screen, which makes the screen extremely easy to deflect, and thus makes it impossible to accurately process or inspect it subsequently. In addition, after the screen deflects, the clamping force applied by the positioning block to the screen will increase, which makes the screen easy to be damaged due to edge collapse.

Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0030] See also Figures 1 to 3 , this embodiment provides a positioning platform, which includes a carrier 1, a first positioning module and a second positioning module, wherein the carrier 1 is configured to carry a product. In this embodiment, the product is a screen. The first positioning module includes a first positioning component 21 and a second positioning component 22 arranged at intervals along a first direction, the first positioning component 21 includes two first positioning blocks 211, the second positioning component 22 includes two second positioning blocks 221, the two first positioning blocks 211 correspond one-to-one with the two second positioning blocks 221, the first positioning component 21 and the second positioning component 22 can move relative to or away from each other, and the second positioning module includes a third positioning component 31 and a fourth positioning component 32 arranged at intervals along a second direction, the second direction is perpendicular to the first direction, the third positioning component 31 includes two third positioning blocks 311, the fourth positioning component 32 includes two fourth positioning blocks 321, the two third positioning blocks 311 correspond one-to-one with the two fourth positioning blocks 321, and the third positioning component 31 and the fourth positioning component 32 can move relative to or away from each other.

[0031] Of course, in other optional embodiments, the first positioning component 21 may also include three or more first positioning blocks 211, and accordingly, the second positioning component 22 may also include three or more second positioning blocks 221, and the third positioning component 31 may also include three or more third positioning blocks 311, and accordingly, the fourth positioning component 32 may also include three or more fourth positioning blocks 321. This embodiment does not impose any specific restrictions on this.

[0032] Based on the above, in this embodiment, the two first positioning blocks 211 are arranged along the second direction, the two second positioning blocks 221 are arranged along the second direction, the two third positioning blocks 311 are arranged along the first direction, and the two fourth positioning blocks 321 are arranged along the first direction. The first positioning component 21, the second positioning component 22, the third positioning component 31 and the fourth positioning component 32 jointly form a loading area. When the first positioning component 21 and the second positioning component 22 move away from each other and the third positioning component 31 and the fourth positioning component 32 move away from each other, the loading area increases so that the screen can be placed in the loading area. Exemplarily, the screen is placed in the loading area with its long side parallel to the second direction and its short side parallel to the first direction. After the screen is placed in the loading area, the first positioning component 21 and the second positioning component 22 move relative to each other, the first positioning component 21 presses against one of the two long sides of the screen, and the second positioning component 22 presses against the other of the two long sides of the screen. The third positioning component 31 and the fourth positioning component 32 move relative to each other, the third positioning component 31 presses against one of the two short sides of the screen, and the fourth positioning component 32 presses against the other of the two short sides of the screen, thereby clamping and positioning the screen.

[0033] From the above, since at least two positioning blocks are provided on either side of the screen during the positioning process, after positioning, there are at least two force points on either side of the screen, which can prevent the screen from deflecting, thereby ensuring that the screen can be accurately processed or inspected subsequently, and at the same time avoid increasing the clamping force applied to the screen, thereby avoiding the problem of edge collapse of the screen and thus avoiding damage to the screen.

[0034] In addition, a perforation 12 is provided on the carrier 1, and the positioning platform also includes a photoelectric sensor 6, which is exposed to the carrier 1 through the perforation 12. The photoelectric sensor 6 can detect whether a screen is placed on the carrier 1, thereby enabling the first positioning component 21 and the second positioning component 22 as well as the third positioning component 31 and the fourth positioning component 32 to move relative to each other after the screen is placed on the carrier 1.

[0035] Furthermore, adsorption holes 11 are provided on the carrier 1 , and a negative pressure environment can be formed in the adsorption holes 11 , so that the screen can be stably placed on the carrier 1 , thereby further preventing the screen from being deflected and damaged.

[0036] Based on the content mentioned above, in this embodiment, the first positioning component 21 is fixed in position. Specifically, the first positioning component 21 is fixedly connected to the carrier 1, and the second positioning component 22 can move toward or away from the first positioning component 21, so that the screen can be placed between the first positioning component 21 and the second positioning component 22 and positioned.

[0037] Exemplarily, the first positioning module further includes a first driving member 23, a first mounting plate 24 and a first elastic member 25. The first driving member 23 is arranged on a side of the second positioning component 22 close to the first positioning component 21, and has a first working state in which the second positioning component 22 is pushed away from the first positioning component 21 to move, and a second working state in which the pushing is released. Specifically, in this embodiment, the movable end of the first driving member 23 is opposite to the adjacent area of the two second positioning blocks 221. When the movable end of the first driving member 23 moves toward the second positioning component 22, the second positioning component 22 moves away from the first positioning component 21. When the movable end of the first driving member 23 moves away from the second positioning component 22 During movement, the first driving member 23 releases the push on the second positioning assembly 22, and the first mounting plate 24 is arranged on the side of the second positioning assembly 22 away from the first positioning assembly 21. Moreover, a first elastic member 25 is provided between any second positioning block 221 and the first mounting plate 24. The first elastic member 25 can be elastically deformed when the first driving member 23 is in the first working state, and can recover the deformation when the first driving member 23 is in the second working state. That is, when the first driving member 23 releases the push on the second positioning assembly 22, the first elastic member 25 can drive the second positioning block 221 to move toward the first positioning block 211, thereby clamping and positioning the screen.

[0038] It can be understood that if the second positioning assembly 22 includes three or more second positioning blocks 221, the movable end of the first driving member 23 can be configured to include a plurality of rake teeth, and all second positioning blocks 221 are correspondingly provided with rake teeth for pushing them to move, so that the first driving member 23 can push the second positioning assembly 22 to move away from the first positioning assembly 21.

[0039] In addition, it is worth noting that in this embodiment, the first driving member 23 is a cylinder. Of course, in other optional embodiments, the first driving member 23 can also be other linear driving structures such as an electric cylinder or an electric push rod, and this embodiment does not impose specific restrictions on this.

[0040] Furthermore, in this embodiment, the position of the third positioning component 31 is fixed. Specifically, the third positioning component 31 is fixedly connected to the carrier 1, and the fourth positioning component 32 can move toward or away from the third positioning component 31, so that the screen can be placed between the third positioning component 31 and the fourth positioning component 32 and positioned.

[0041] Exemplarily, the second positioning module further includes a second driving member 33, a second mounting plate 34 and a second elastic member 35. The second driving member 33 is arranged on a side of the fourth positioning component 32 close to the third positioning component 31, and has a third working state in which the fourth positioning component 32 is pushed away from the third positioning component 31 to move, and a fourth working state in which the pushing is released. Specifically, in this embodiment, the movable end of the second driving member 33 is opposite to the adjacent area of the two fourth positioning blocks 321. When the movable end of the second driving member 33 moves toward the fourth positioning component 32, the fourth positioning component 32 moves away from the third positioning component 31, and the movable end of the second driving member 33 moves away from the fourth positioning component When the second driving member 33 moves, the second driving member 33 releases the push on the fourth positioning assembly 32, and the second mounting plate 34 is arranged on the side of the fourth positioning assembly 32 away from the third positioning assembly 31. A second elastic member 35 is provided between any fourth positioning block 321 and the second mounting plate 34. The second elastic member 35 can be elastically deformed when the second driving member 33 is in the third working state, and can recover the deformation when the second driving member 33 is in the fourth working state. That is, when the second driving member 33 releases the push on the fourth positioning assembly 32, the second elastic member 35 can drive the fourth positioning block 321 to move toward the third positioning block 311, thereby clamping and positioning the screen.

[0042] It can be understood that if the fourth positioning assembly 32 includes three or more fourth positioning blocks 321, the movable end of the second driving member 33 can also be configured to include a plurality of rake teeth, and all fourth positioning blocks 321 are correspondingly provided with rake teeth for pushing them to move, so that the second driving member 33 can push the fourth positioning assembly 32 to move away from the third positioning assembly 31.

[0043] In addition, it is worth noting that in this embodiment, the second driving member 33 is a cylinder. Of course, in other optional embodiments, the second driving member 33 can also be other linear driving structures such as an electric cylinder or an electric push rod, and this embodiment does not impose specific restrictions on this.

[0044] Furthermore, the positioning platform also includes a first slide rail 41 and a second slide rail 42, the first slide rail 41 extends along the first direction, the second positioning block 221 is slidably connected to the first slide rail 41, the second slide rail 42 extends along the second direction, and the fourth positioning block 321 is slidably connected to the second slide rail 42, so that the second positioning block 221 and the fourth positioning block 321 can be guided when the second positioning block 221 and the fourth positioning block 321 move, thereby further preventing the screen from deflecting and being damaged.

[0045] In addition, the positioning platform also includes a third mounting plate 51 and a fourth mounting plate 52. The carrier 1, the first positioning module and the second positioning module are all mounted on the third mounting plate 51. The third mounting plate 51 is detachably mounted on the fourth mounting plate 52. The first positioning module, the second positioning module and the third mounting plate 51 constitute a positioning module. For different types of screens, this embodiment can be equipped with different positioning modules. During the production process, when the screen is changed, the staff directly removes the third mounting plate 51 from the fourth mounting plate 52 and replaces it with a positioning module corresponding to the changed screen. Compared with disassembling and assembling the first positioning module and the second positioning module, this embodiment can shorten the disassembly and replacement cycle, thereby improving production efficiency.

[0046] Based on the above, in this embodiment, the first slide rail 41 , the second slide rail 42 and the photoelectric sensor 6 are all mounted on the third mounting plate 51 .

[0047] It should also be noted that the fourth mounting plate 52 is provided with a gas socket 521 and an electric socket 522, and the third mounting plate 51 is provided with a gas plug 511 and an electric plug 512. When the third mounting plate 51 is installed on the fourth mounting plate 52, the gas plug 511 is plugged into the gas socket 521, and the electric plug 512 is plugged into the electric socket 522. That is, in this embodiment, when the screen is changed, the staff directly removes the third mounting plate 51 from the fourth mounting plate 52 and replaces it with a positioning module corresponding to the changed screen. On the one hand, the staff does not need to disassemble and install the first positioning module and the second positioning module. On the other hand, the staff also does not need to disassemble and install the gas circuit for supplying gas to the structure installed on the third mounting plate 51 and the circuit for supplying power to the structure installed on the third mounting plate 51, thereby further shortening the disassembly and replacement cycle, and further improving production efficiency.

[0048] Of course, in other optional embodiments, the gas plug 511 may be set on the fourth mounting plate 52, and correspondingly, the gas socket 521 may be set on the third mounting plate 51. Similarly, in other optional embodiments, the electric plug 512 may be set on the fourth mounting plate 52, and correspondingly, the electric socket 522 may be set on the third mounting plate 51. This embodiment does not impose any specific restrictions on this.

[0049] Based on the content mentioned above, after the third mounting plate 51 is installed on the fourth mounting plate 52, the air plug 511 is connected to the air socket 521, so that on the one hand it can supply air to the first driving member 23 and the second driving member 33, and on the other hand it can also form a negative pressure environment in the adsorption hole 11, and the electric plug 512 is connected to the electric socket 522, so that it can supply power to the photoelectric sensor 6.

[0050] It is understandable that if the first driving member 23 and / or the second driving member 33 is an electric cylinder or an electric push rod, the connected electric plug 512 and the electric socket 522 can be used to supply power to the first driving member 23 and / or the second driving member 33.

[0051] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
