The second drive unit 32 is arranged on the main frame 1, and by connecting the second support member 31 with the drive end of the second drive unit 32, the second support member 31 can be driven to move under the action of the second drive unit 32, so that the second support member 31 can be moved away from or close to the edge of the shell 8 along the second direction, thereby conveniently realizing the position alternation of the first positioning component 2 and the second positioning component 3, making the use of the second positioning component 3 more convenient.

[0040] Among them, a positioning structure is also provided on the second support member 31, and the positioning structure can be a groove structure whose shape is adapted to the shape of the edge of the shell 8.

[0041] like Figure 6As shown, in order to facilitate the connection between the second driving unit 32 and the second support member 31, a cooling mounting frame may be further provided between the second driving unit 32 and the second support member 31. The cooling mounting frame refers to a frame member having a certain shape, and the installation area of ​​the second support member 31 may be increased by providing the cooling mounting frame, so that the installation of the second support member 31 may be more stable and firm.

[0042] In one embodiment, Figure 6 As shown, the second drive unit 32 is slidably connected with the main frame 1, and a translation drive unit 33 is provided on the main frame 1, and the translation drive unit 33 is used to drive the second drive unit 32 and the second support member 31 to move along the first direction.

The second drive unit 32 is slidably connected with the main frame 1, so that the second drive unit 32 can slide along the first direction under the action of the translation drive unit 33. After the second drive unit 32 moves the second support member 31 to a certain position along the second direction, the second drive unit 32 and the second support member 31 can be pushed by the translation drive unit 33 to slide along the first direction as a whole, so that the second support member 31 is closer to the edge of the housing 8 more conveniently, and at the same time, the second support member 31 can be prevented from interfering with the first support member 22 during the movement, so that the movement of the second support member 31 is safer.

[0043] In an optional embodiment, if Figure 6 As shown, a slide rail assembly 7 is also provided between the second drive unit 32 and the main frame 1, wherein the slide rail assembly 7 generally includes a slide rail and a slider that can slide along the length direction of the slide rail. When the second drive unit 32 is connected and installed with the main frame 1, the slide rail can be set on the main frame 1, and the second drive unit 32 is connected with the slider to realize the sliding connection between the mobile bracket 21 and the main frame 1, making the sliding of the second drive unit 32 more convenient.

[0044] Among them, in order to facilitate the installation of the second drive unit 32, a drive bracket can also be arranged between the second drive unit 32 and the main frame 1. The drive bracket is slidably connected to the main frame 1 through the slide rail assembly 7, and the second drive unit 32 is then arranged on the drive bracket.

By arranging the clamping fixture 41 at the driving end of the clamping drive unit 42, the clamping drive unit 42 can drive the clamping fixture 41 to move, so that the clamping fixture 41 can cooperate with the positioning structure on the first support member 22 or the second support member 31 to clamp and fix the edge of the shell 8, which can make the use of the clamping assembly 4 more convenient and make the positioning of the shell more secure.

[0046] The movement direction of the clamping fixture 41 is generally along the vertical direction, so that the movement path of the clamping fixture 41 is the shortest when the clamping fixture 41 is clamping the edge of the housing 8.

Both the hot pressing end 411 and the cold pressing end 412 can move in the vertical direction under the action of the clamping drive unit 42. By dividing the clamping fixture 41 into the hot pressing end 411 and the cold pressing end 412, mutual interference between the hot pressing end 411 and the cold pressing end 412 is avoided.

[0048] In one embodiment, Figure 2 As shown, the first positioning assembly 2, the second positioning assembly 3 and the pressing assembly 4 constitute an edge positioning structure, and the number of edge positioning structures is two, and the two edge positioning structures are relatively arranged on the main frame 1. Specifically, the two sets of edge positioning structures can be arranged at intervals along the first direction, and the housing 8 can be placed between the two sets of edge positioning structures. By positioning both sides of the housing 8 at the same time through the two sets of edge positioning structures, the positioning of the housing 8 can be made more secure and more accurate.

[0049] In one embodiment, Figure 1As shown, the main frame 1 is provided with a first clamping claw 51, a second clamping claw 52 and a clamping drive unit 53, at least one of the first clamping claw 51 and the second clamping claw 52 is movably arranged on the main frame 1, and the two are used to cooperate with each other to clamp the shell 8, and the clamping drive unit 53 is used to drive the first clamping claw 51 and the second clamping claw 52 to move closer to or farther from each other.

Only one of the first clamping claw 51 and the second clamping claw 52 can move, or both can move. The first clamping claw 51 and the second clamping claw 52 can move closer to or farther from each other under the action of the clamping drive unit 53, and when the shell 8 needs to be positioned, the two sides of the shell 8 can be clamped and fixed along the third direction, which can further improve the accuracy of the positioning of the shell 8 and make the shell 8 more firmly and reliably fixed.

[0050] The number of the first clamping claws 51 and the number of the second clamping claws 52 can be multiple, and the multiple first clamping claws 51 can be arranged in sequence along the edge of the shell 8. The multiple second clamping claws 52 can also be arranged in sequence along the edge of the shell 8, so that the clamping and fixing of the shell 8 can be more stable.

[0051] In an optional embodiment, the clamping drive unit 53 generally refers to a component that can drive other components to reciprocate, and the clamping drive unit 53 can be a cylinder, an electric push rod, or a hydraulic push rod, etc. The first clamping jaw 51 and the second clamping jaw 52 can share a clamping drive unit 53, so that the first clamping jaw 51 and the second clamping jaw 52 can be driven to move by the two clamping drive units 53, respectively, so that the first clamping jaw 51 and the second clamping jaw 52 can clamp and fix the housing 8 more conveniently.

The buffer unit 54 can play a certain buffering role when the first clamping jaw 51 and the second clamping jaw 52 clamp the housing 8, thereby avoiding deformation of the housing 8 due to excessive clamping force of the first clamping jaw 51 and the second clamping jaw 52, ​​thereby making the clamping and fixing of the housing 8 safer and more reliable.

[0053] When positioning the shell 8 along the third direction, the first clamping claw 51 is used as the reference side, and the second clamping claw 52 provided with the buffer unit 54 is only used as the auxiliary side, so that the clamping of the shell 8 is more convenient and the positioning of the shell 8 along the third direction is more accurate.

When the shell 8 is clamped, the movable member 541 can slide along the sliding rod 542 to adjust the position of the movable member 541, and the elastic member 543 is arranged between the movable member 541 and the second clamping claw 52 to achieve the buffering effect, so that the installation of the entire buffer unit 54 can be more stable and firm, and the structure of the buffer unit 54 can also be made simpler.

[0055] In one embodiment, Figure 2 As shown, the positioning device also includes a vacuum unit 6, and the vacuum unit 6 is arranged on the support surface, and the vacuum unit 6 is arranged on the support surface, and the vacuum unit 6 is located between the two edge positioning structures, and the vacuum unit 6 is used to adsorb the shell 8 on the support surface. Specifically, the vacuum unit 6 refers to a component that can adsorb the shell 8 by generating negative pressure. Through the setting of the vacuum unit 6, when the first clamping claw 51 and the second clamping claw 52 loosen the shell 8, and at the same time, the first positioning component 2 and the second positioning component 3 both loosen the shell 8, the shell 8 can still be kept fixed under the action of the vacuum unit 6, which can prevent the shell 8 from moving at the moment when the two positioning components are loosened, so that the positioning of the shell 8 can be made safer and more firm, and the positioning of the shell 8 can also be made more accurate.

[0056] Among them, the vacuum unit 6 may include a support block and a certain number of adsorption holes arranged on the support block, and the adsorption holes are all connected to the vacuum generating device. The support block can support the shell 8 and adsorb the shell 8 through the adsorption holes at the same time, thereby making the use of the vacuum unit 6 more convenient.
