[0039] Reference Figure 1As shown, the upper surface 21 of the bearing platform 20 is provided with a placement area 211 in the fixing device 200 of an embodiment of the present application. The bearing platform 20 is correspondingly provided with a plurality of through hole groups, each of which is arranged along the circumference of the placement area 211, for example, each group of through holes is arranged on one side of an edge of the placement area 211. The through hole group is provided with a plurality of strip-shaped through holes 23. It should be noted that in an embodiment of the present application, the shape of the placement area 211 is rectangular, and four groups of through hole groups are correspondingly arranged. However, the present application is not limited to this, the shape of the placement area 211 can also be a regular polygon such as a triangle, a pentagon, or an irregular polygon. In other embodiments, the strip-shaped through holes 23 can not be limited to be straight, and the shape of the strip-shaped through holes 23 can also be arc-shaped or meander-shaped. In addition, the number of through hole groups is not limited to one group, and the number of through hole groups is greater than or equal to one group.

[0040] Referring to Figure 3 As shown, the fixing device 200 is also provided with one or more than one compression module 100, for example, the number of compression modules 100 is four. Each compression module 100 is assembled with the bearing platform 20, for example, part of the compression module 100 is assembled on the lower surface 22 of the bearing platform 20. The compression module 100 is correspondingly arranged with the position of the through hole group provided in the bearing platform 20, so that when the compression module 100 is assembled on the bearing platform 20, the compression piece 12 passes through the bearing platform 20 through the through hole group, and the compression piece 12 in the compression module 100 is located on one side of the upper surface 21.

[0041] Referring to Figure 1 As shown, since the through hole group is arranged along the circumference of the placement area 211, when the compression module 100 is assembled on the bearing platform 20, the compression piece 12 of the compression module 100 forms a rectangular compression area in the upper surface 21 of the bearing platform 20. Since the compression module 100 is configured to move relative to the bearing platform 20 along the extension direction of the strip-shaped through hole 23, the compression piece 12 for compressing the workpiece can move along the extension direction of the strip-shaped through hole 23 towards the placement area 211, or the compression piece 12 moves along the extension direction of the strip-shaped through hole 23 away from the placement area 211.

[0042] Therefore, the area of the rectangular compression area formed by the compression piece 12 of each compression module 100 can be changed, that is, according to the fixing device 200 of the present application, by driving the compression module 100 to move relative to the bearing platform 20 along the extension direction of the strip-shaped through hole 23, the area of the compression area is changed, so that the compression module 100 in the fixing device 200 is suitable for compressing workpieces of different area sizes on the upper surface 21 of the bearing platform 20, thereby improving the versatility of the fixing device 200.

[0043] In addition, the compression modules and the bearing platform in the current fixing device are in a relatively static state. In order to enable the fixing device to be used for fixing a workpiece with a large area size, the area of the placement region in the bearing platform is usually set to be large. However, in this case, for example, the placement region of the bearing platform has a negative pressure form to adsorb and fix the workpiece on the bearing platform. When the area size of the workpiece is smaller than the area size of the placement region, that is, the workpiece cannot cover the placement region, the part of the placement region that is not covered by the workpiece can continuously suck in gas from the environment, that is, the workpiece will leak vacuum in the case that the workpiece cannot completely cover the placement region, which also causes the workpiece to be unable to be reliably adsorbed and fixed on the bearing platform.

[0044] Therefore, the current fixing device needs to be equipped with a complete plate to cover the part of the bearing platform that leaks vacuum, so as to avoid the occurrence of the vacuum leakage. However, the size of the workpiece is different, and therefore, in order to enable the fixing device to adapt to workpieces with different sizes, multiple sizes of complete plates need to be prepared. Therefore, the current fixing device needs to be prepared with different sizes of complete plates for processing workpieces.

[0045] Compared with the current fixing device, the area size of the placement region 211 in the bearing platform 20 according to the present application is designed to be smaller than or equal to the minimum area size of the workpiece to be used, so as to ensure that the workpiece with the minimum area size will not leak vacuum when placed on the upper surface 21 of the bearing platform 20, and the compression modules 100 can be driven to move along the strip-shaped through hole 23 towards the direction close to the placement region 211, so that the compression members 12 of the compression modules 100 can compress the workpiece on the upper surface 21 of the bearing platform 20. For the workpiece with an area size larger than the placement region 211, the compression modules 100 can be driven to move along the strip-shaped through hole 23 towards the direction away from the placement region 211, so as to increase the area of the compression surface formed by the compression members 12 of the multiple compression modules 100, and the compression members 12 of the compression modules 100 can compress the workpiece with an area size larger than the placement region 211 on the upper surface 21 of the bearing platform 20.

[0046] Therefore, the bearing platform 20 according to the present application does not need to be equipped with a complete plate, and there is no vacuum leakage, so as to improve the adsorption stability of the workpiece on the upper surface 21 of the bearing platform 20, and the area size range of the workpiece that can be fixed by the fixing device 200 is large, so that the fixing device 200 has high versatility.

[0047] In summary, the fixing device 200 according to the present application can avoid the occurrence of the vacuum leakage, and the fixing device 200 can also be applied to different sizes of workpieces to be processed. Therefore, the fixing device 200 according to the present application can not only improve the adsorption stability of the workpiece on the bearing platform 20, but also has high versatility.

[0048] Referring to Figure 1 and Figure 2 In some embodiments of the present application, a plurality of adsorption holes 24 are arranged in the placement area 211, and the adsorption holes 24 are used in communication with the negative pressure generator to form a negative pressure in the adsorption holes 24, so that the workpiece placed on the placement area 211 is adsorbed and fixed to the upper surface 21 of the bearing platform 20.

[0049] In an embodiment, the bearing platform 20 is provided with a negative pressure cavity, the negative pressure cavity is in communication with each adsorption hole 24, and the negative pressure cavity is also in communication with the negative pressure generator. It can also be understood that the negative pressure cavity is used to converge the gas in the plurality of adsorption holes 24, and at the same time, due to the communication between the negative pressure cavity and the negative pressure generator, the negative pressure cavity is in a negative pressure state under the action of the negative pressure cavity. In this way, each adsorption hole 24 is in a negative pressure state, thereby achieving the effect that the workpiece placed on the placement area 211 is adsorbed and fixed to the upper surface 21 of the bearing platform 20. Referring to Figure 3 As shown in the figure, the fixing device 200 further comprises a suction pipe 25, the suction pipe 25 is fixed to the lower surface 22 of the bearing platform 20, and one end of the suction pipe 25 is in communication with the negative pressure cavity, and the other end of the suction pipe 25 is used in communication with the negative pressure generator, so that the negative pressure generator communicates with the negative pressure cavity through the suction pipe 25.

[0050] In another embodiment, the fixing device 200 further comprises a plurality of air guide pipes, one end of the air guide pipe is arranged in the adsorption hole 24, and the other end of the air guide pipe is used in communication with the negative pressure generator. That is, the plurality of adsorption holes 24 in the placement area 211 are respectively communicated with one negative pressure generator through the plurality of air guide pipes, so that each adsorption hole 24 is in a negative pressure state under the action of the negative pressure generator, so that the workpiece placed on the placement area 211 is adsorbed and fixed to the upper surface 21 of the bearing platform 20.

[0051] It should be noted that in some of the above embodiments, the negative pressure generator can be a vacuum pump, and the negative pressure cavity can be a vacuum cavity. The bearing platform corresponding to the vacuum pump and the vacuum cavity is a vacuum adsorption platform.

[0052] Referring to Figure 1As shown, in some embodiments of the present application, since the compression module 100 is arranged to pass through the through hole group to the bearing platform 20, the compression piece 12 in the compression module 100 is located on one side of the upper surface 21 of the bearing platform 20. By arranging each group of through holes to be perpendicular to one edge of the placement area 211, it can also be understood that the perpendicular line of the arrangement direction of the plurality of strip-shaped through holes 23 in each group of through holes is arranged to be perpendicular to one edge of the placement area 211, that is, the arrangement direction of the plurality of strip-shaped through holes 23 in each group of through holes is arranged to be parallel to one edge of the placement area 211, so that the compression piece 12 is arranged to be parallel to the edge of the placement area 211.

[0053] In combination Figures 3 to 6 As shown, in some embodiments of the present application, the compression module 100 includes a compression assembly 1 and an assembly base 2. The compression assembly 1 includes a moving piece 11 and a compression piece 12, and the compression piece 12 is detachably assembled to the moving piece 11 to facilitate replacement of different types of compression pieces 12. The moving piece 11 is assembled to the assembly base 2, and the assembly base 2 is assembled to the lower surface 22 of the bearing platform 20. It should be noted that in some embodiments, the fixing device 200 further includes at least one group of sliding assemblies 6, and the assembly base 2 is reciprocally movably assembled to the lower surface 22 through the sliding assembly 6, that is, the assembly base 2 is indirectly assembled to the lower surface 22 of the bearing platform 20.

[0054] Referring to Figure 5 And Figure 6 As shown, the compression piece 12 arranged in the compression module 100 is a replaceable piece, and the type of the compression piece 12 can be divided into a point-shaped compression piece 121 and a strip-shaped compression piece 122. When the compression piece 12 is a point-shaped compression piece 121, a single compression piece 12 includes a plurality of point-shaped compression parts, and when the compression piece 12 is a strip-shaped compression piece 122, a single compression piece 12 includes at least one strip-shaped compression part. That is, the compression piece 12 includes one of a plurality of point-shaped compression parts and at least one strip-shaped compression part.

[0055] By replacing different types of compression pieces 12, the fixing device 200 can be suitable for workpieces made of different materials. It should be noted that, for example, the workpiece is a circuit board, and for the circuit board, the circuit board includes a hard circuit board and a flexible circuit board, and the flexible circuit board has excellent flexibility and bendability relative to the hard circuit board, that is, the flexible circuit board is more easily deformed relative to the hard circuit board.

[0056] For the rigid circuit board, the pressing member 12 in the pressing module 100 can be selected as having a point-like pressing portion or a strip-like pressing portion (i.e. can be selected as a point-like pressing member 121 or a strip-like pressing member 122), but for the flexible circuit board, the pressing member 12 in the pressing module 100 can only be selected as having a strip-like pressing portion, thus by setting the pressing member 12 in the pressing module 100 as a replaceable member, the fixing device 200 can be simultaneously applied to the rigid circuit board and the flexible circuit board, so that the fixing device 200 has higher versatility.

[0057] The pressing module 100 further comprises a driving assembly, which is used to drive the moving member 11 to reciprocate along the thickness direction of the bearing platform 20 relative to the assembly base 2, so as to drive the pressing member 12 assembled on the moving member 11 to ascend and descend along the thickness direction of the bearing platform 20, so that the pressing member 12 is used to press and fix the workpiece to be processed on the upper surface 21 of the bearing platform 20. The driving assembly is also used to drive the assembly base 2 to drive the moving member 11 to reciprocate along the extension direction of the strip-shaped through hole 23, so as to drive the pressing module 100 to move relative to the bearing platform 20 along the extension direction of the strip-shaped through hole 23, so as to change the area size of the pressing surface domain, so that the pressing module 100 in the fixing device 200 is suitable for pressing the workpiece to be processed with different area sizes on the upper surface 21 of the bearing platform 20.

[0058] In some embodiments of the present application, the moving member 11 comprises a plurality of assembly columns 111, which are arranged through the bearing platform 20 through the strip-shaped through hole 23, so that the pressing member 12 can be assembled on the top end of the assembly column 111 from the side of the upper surface 21 of the bearing platform 20, so as to realize that the pressing member 12 is assembled on the moving member 11 and located on the side of the upper surface 21 of the bearing platform 20, so that the pressing member 12 can be used to press the workpiece to be processed on the upper surface 21 of the bearing platform 20.

[0059] Referring to Figure 5 and Figure 6 , it is shown that the pressing member 12 comprises a plurality of point-like pressing portions, each of which is correspondingly assembled with each assembly column 111, or the pressing member 12 comprises at least one strip-like pressing portion, and a single strip-like pressing portion is assembled with a plurality of assembly columns 111. For example, referring to Figure 5 , it is shown that the pressing member 12 comprises a plurality of point-like pressing portions, each of which is correspondingly assembled with each assembly column 111, or the pressing member 12 comprises at least one strip-like pressing portion, and a single strip-like pressing portion is assembled with a plurality of assembly columns 111. For example, referring to Figure 5 , it is shown that the type of the pressing member 12 is the pressing module 100 comprising a plurality of point-like pressing portions, or referring to Figure 6 , it is shown that the type of the pressing member 12 is the pressing module 100 comprising a plurality of point-like pressing portions, or referring to Figure 6 , it is shown that the type of the pressing member 12 is the pressing module 100 comprising two strip-like pressing portions.

[0060] It should be noted that when the compression module 100 is assembled on the bearing platform 20, each assembly column 111 arranged in the moving piece 11 is respectively penetrated through a strip-shaped through hole 23, and in the process of moving the compression module 100 along the extension direction of the strip-shaped through hole 23, the strip-shaped through hole 23 and the assembly column 111 play a guiding cooperation role, which ensures the stability of the movement of the assembly column 111, and since the compression piece 12 is assembled on the assembly column 111, the stability of the compression piece 12 is also improved.

[0061] Referring to Figure 5 and Figure 6 In some embodiments of the present application, the moving piece 11 is provided with a first sliding piece 51, and the assembly base 2 is provided with a second sliding piece 52, and the first sliding piece 51 and the second sliding piece 52 are slidingly matched along the thickness direction of the bearing platform 20.

[0062] In an embodiment, as shown in Figure 5 and Figure 6 The first sliding piece 51 is a sliding block, the second sliding piece 52 is a sliding rail, the sliding block is slidably assembled on the sliding rail (i.e., the first sliding piece 51 and the second sliding piece 52 are slidingly matched), and when the compression module 100 is assembled on the bearing platform 20, the extension direction of the sliding rail is arranged in parallel with the thickness direction of the bearing platform 20, so that the sliding block assembled on the sliding rail can slide along the thickness direction of the bearing platform 20, thereby realizing the sliding of the moving piece 11 along the thickness direction of the bearing platform 20 relative to the assembly base 2. It should be noted that in another embodiment of the present application, the first sliding piece 51 can be a sliding block, and the second sliding piece 52 is correspondingly arranged as a sliding rail.

[0063] It should be noted that in some embodiments described above, the first sliding piece 51 can be a component assembled on the moving piece 11, and the second sliding piece 52 can be a component assembled on the assembly base 2. However, the present application is not limited thereto, and the first sliding piece 51 can be part of the structure of the moving piece 11, and the second sliding piece 52 can be part of the structure of the assembly base 2. It can also be understood that the moving piece 11 is formed with the first sliding piece 51, and the assembly base 2 is formed with the second sliding piece 52.

[0064] In combination with Figures 3 to 5As shown in the drawings, in some embodiments of the present application, the fixing device 200 further comprises at least one set of sliding assembly 6, wherein the sliding assembly 6 comprises a guide rail 61 and a guide slider 62 in a guide fit, the guide rail 61 is assembled on the lower surface 22 and extends along the extension direction of the strip-shaped through hole 23, and the guide slider 62 is fixedly assembled on the assembly base 2. Since the guide rail 61 extends along the extension direction of the strip-shaped through hole 23, the movement track of the guide slider 62 during the movement along the guide rail 61 is consistent with the extension direction of the strip-shaped through hole 23, so that the movement track of the assembly base 2 to which the guide slider 62 is fixedly assembled is consistent with the extension direction of the strip-shaped through hole 23, so that the compression module 100 is adapted to move along the extension direction of the strip-shaped through hole 23 relative to the bearing platform 20.

[0065] It should be noted that, as shown in Figure 5 and Figure 6 In some embodiments of the compression module 100 of the present application, a plurality of sets of sliding assemblies 6 are arranged in parallel. By arranging a plurality of sets of sliding assemblies 6, the plurality of sliding assemblies 6 can restrict each other during the movement of the assembly base 2, so as to reduce the risk of deflection of the assembly base 2, thereby effectively improving the movement stability of the assembly base 2, so that the movement track of the compression member 12 is more accurate, and the movement accuracy of the compression member 12 is ensured, so that the fixing device 200 has high precision.

[0066] As shown in Figure 5 and Figure 6 In some embodiments of the present application, the driving assembly comprises a first driver 3 and a second driver 4. The first driver 3 is fixedly assembled on the assembly base 2, and the first driver 3 is further connected with the moving member 11, so that the first driver 3 is used to drive the moving member 11 to reciprocate along the thickness direction of the bearing platform 20 relative to the assembly base 2, that is, to realize the lifting movement of the compression member 12 assembled on the moving member 11, so that the compression member 12 can be used to compress the workpiece to be processed on the upper surface 21 of the bearing platform 20. The second driver 4 is fixedly assembled on the lower surface 22 of the bearing platform 20, and the second driver 4 is connected with the assembly base 2, so that the second driver 4 is used to drive the assembly base 2 to reciprocate along the extension direction of the strip-shaped through hole 23, that is, to realize the effect that the compression module 100 moves along the extension direction of the strip-shaped through hole 23 relative to the bearing platform 20.

[0067] In one embodiment, as shown in Figure 5 and Figure 6As shown, the first driver 3 can include a driving body 31 and a rod body (not shown in the figure), the driving body 31 is used to drive the rod body to move along the axial direction of the rod body. Wherein the driving body 31 is fixedly assembled to the assembly base 2, and the rod body is connected with the moving piece 11 at the end away from the driving body 31, so that the moving piece 11 can be moved relative to the assembly base 2 by driving the rod body to move through the driving body 31. It should be added that the axial direction of the rod body is parallel to the thickness direction of the bearing platform 20, so that the moving piece 11 can reciprocate relative to the assembly base 2 along the thickness direction of the bearing platform 20. In this embodiment, taking the first driver 3 as an example of a lifting cylinder, the driving body 31 is the cylinder body of the lifting cylinder, and the rod body is the piston rod. In addition, the first driver 3 can also be a hydraulic lifter.
