Referring to fig. 1, in a fixing device 200 according to an embodiment of the application, a placement area 211 is disposed on an upper surface 21 of a carrying platform 20. The carrying platform 20 is correspondingly provided with through hole groups, and each through hole group is sequentially arranged along the circumferential direction of the placement area 211, for example, each through hole group is correspondingly arranged at one side of one edge of the placement area 211. A plurality of bar-shaped through holes 23 are provided in the through hole group. It should be noted that, in the embodiment of the present application, the placement area 211 is rectangular, and four groups of through holes are correspondingly provided, but the present application is not limited thereto, and the placement area 211 may be regular polygon such as triangle, pentagon, etc., or irregular polygon, and in other embodiments, the strip-shaped through holes 23 may not be limited to be linear, the shape of the strip-shaped through holes 23 may be arc-shaped or circular, etc., and the number of the through holes is not limited to one group, and the number of the through holes may be greater than or equal to one group.

Referring to fig. 3, the fixing device 200 is further provided with more than one compression module 100, for example, four compression modules 100, wherein each compression module 100 is assembled with the carrying platform 20, for example, a portion of the compression modules 100 is assembled with the lower surface 22 of the carrying platform 20. The pressing module 100 is disposed corresponding to the position of the bearing platform 20 where the through hole set is disposed, so that when the pressing module 100 is assembled on the bearing platform 20, the pressing member 12 passes through the through hole set to penetrate through the bearing platform 20, so that the pressing member 12 in the pressing module 100 is located on the upper surface 21 side.

Referring to fig. 1, since the through-hole groups are arranged along the circumferential direction of the placement area 211, the pressing member 12 of the pressing module 100 forms a pressing area having a rectangular shape in the upper surface 21 of the loading platform 20 when the pressing module 100 is assembled to the loading platform 20. Further, since the pressing module 100 is configured to move in the extending direction of the bar-shaped through hole 23 with respect to the carrying platform 20, the pressing member 12 for pressing the workpiece to be processed can be moved in the extending direction of the bar-shaped through hole 23 toward the direction approaching the placing area 211, or the pressing member 12 can be moved in the extending direction of the bar-shaped through hole 23 toward the direction away from the placing area 211.

Based on this, the area of the pressing area formed into a rectangular shape by the pressing members 12 of each pressing module 100 can be changed, that is, according to the fixing device 200 of the present application, the pressing modules 100 are driven to move relative to the carrying platform 20 along the extending direction of the bar-shaped through holes 23, so that the area of the pressing area is changed, so that the pressing modules 100 in the fixing device 200 are suitable for pressing workpieces with different area sizes onto the upper surface 21 of the carrying platform 20, thereby improving the versatility of the fixing device 200.

In addition, the compression module and the carrying platform in the conventional fixing device are in a relatively static state, so that the fixing device can be used for fixing a workpiece with a larger area size, and the area of the placing area in the carrying platform is generally set to be larger. However, in this case, for example, the placement area of the carrying platform has a negative pressure form to adsorb and fix the workpiece to the carrying platform, so that when the area size of the workpiece to be machined is smaller than that of the placement area, that is, the portion of the workpiece to be machined cannot cover the placement area, so that for fixing the workpiece to the carrying platform by the negative pressure form, since the portion of the workpiece to be machined in the placement area can continuously suck gas from the environment, that is, the workpiece to be machined cannot be adsorbed and fixed to the carrying platform reliably due to the phenomenon of vacuum leakage which occurs when the portion of the workpiece to be machined cannot completely cover the placement area.

Based on this, the current fixing device needs to be equipped with a complete plate to cover the vacuum-leaking part of the carrying platform, so as to avoid the occurrence of vacuum-leaking. However, the sizes of the workpieces to be processed are different, so that a plurality of sized finished plates need to be prepared in a targeted manner in order to be able to adapt to the workpieces to be processed with different sizes. It follows that the use of the current fixing devices for the machining of the workpieces to be machined requires the preparation of finished plates of different dimensions.

Compared with the prior fixing device, the area size of the placement area 211 in the carrying platform 20 is designed to be smaller than or equal to the applicable minimum area size of the workpiece to be processed, so that the workpiece to be processed with the minimum area size is ensured not to leak vacuum when being placed on the upper surface 21 of the carrying platform 20, and meanwhile, the compressing module 100 can be driven to move along the strip-shaped through hole 23 towards the direction approaching to the placement area 211, so that the compressing piece 12 of the compressing module 100 compresses the workpiece to be processed on the upper surface 21 of the carrying platform 20. For the workpiece to be processed with the area size larger than the placement area 211, the pressing piece 12 of the pressing module 100 presses the workpiece to be processed with the area size larger than the placement area 211 on the upper surface 21 of the carrying platform 20 by driving the pressing module 100 to move along the strip-shaped through hole 23 in a direction away from the placement area 211, so that the area of the pressing area constructed by the pressing pieces 12 of the plurality of pressing modules 100 is increased.

Therefore, the carrying platform 20 does not need to be provided with a complete plate, and no vacuum leakage exists, so that the adsorption stability of the workpiece to be processed on the upper surface 21 of the carrying platform 20 is improved, and the area size range of the workpiece to be processed, which can be fixed by the fixing device 200, is larger, so that the fixing device 200 has higher universality.

In view of the above, the fixing device 200 according to the present application can avoid occurrence of vacuum leakage, and the fixing device 200 can also be applied to workpieces to be processed having different area sizes. Therefore, the fixing device 200 according to the application not only can improve the adsorption stability of the workpiece to be processed on the carrying platform 20, but also has higher universality.

Referring to fig. 1 and 2, in some embodiments of the present application, a plurality of suction through holes 24 are provided in the placement area 211, and the suction through holes 24 are used for communicating with a negative pressure generator to form a negative pressure in the suction through holes 24, so that a workpiece to be processed placed on the placement area 211 is fixed on the upper surface 21 of the carrying platform 20 by suction.

In one embodiment, a negative pressure cavity is disposed in the carrying platform 20 and is communicated with each adsorption through hole 24, and the negative pressure cavity is also communicated with the negative pressure generator, which can be understood that the negative pressure cavity is used for converging the gases in the plurality of adsorption through holes 24, and meanwhile, the negative pressure cavity is also communicated with the negative pressure generator, so that the negative pressure cavity is in a negative pressure state under the action of the negative pressure cavity, and thus, each adsorption through hole 24 is in a negative pressure state, and the effect that the workpiece to be machined placed on the placement area 211 is adsorbed and fixed on the upper surface 21 of the carrying platform 20 is achieved. Referring to fig. 3, the fixing device 200 further includes an air suction pipe 25, wherein the air suction pipe 25 is assembled and fixed on the lower surface 22 of the carrying platform 20, and one interface of the air suction pipe 25 is communicated with the negative pressure cavity, and the other interface of the air suction pipe 25 is used for communicating with the negative pressure generator, so that the negative pressure generator communicates with the negative pressure cavity through the air suction pipe 25.

In another embodiment, the fixing device 200 further includes a plurality of air ducts, wherein one interface of the air ducts is installed in the adsorption through hole 24, and the other interface of the air ducts is used for communicating with a negative pressure generator, that is, the plurality of adsorption through holes 24 in the placement area 211 are respectively communicated with one negative pressure generator through the plurality of air ducts, and each adsorption through hole 24 is in a negative pressure state under the action of the negative pressure generator, so that the workpiece to be processed placed on the placement area 211 is adsorbed and fixed on the upper surface 21 of the carrying platform 20.

It should be noted that in some embodiments, the negative pressure generator may be a vacuum pump, the negative pressure cavity is a vacuum cavity, and the bearing platform corresponding to the vacuum pump and the vacuum cavity is a vacuum adsorption platform.

Referring to fig. 1, in some embodiments of the present application, since the pressing module 100 passes through the through hole set to penetrate the carrying platform 20, the pressing member 12 in the pressing module 100 is located on the upper surface 21 side of the carrying platform 20. By arranging each set of through-holes perpendicular to one edge of the placement area 211, it is also understood that the perpendicular to the arrangement direction of the plurality of strip-shaped through-holes 23 in each set of through-holes is perpendicular to one edge of the placement area 211, i.e., the arrangement direction of the plurality of strip-shaped through-holes 23 in each set of through-holes is parallel to one edge of the placement area 211, so that the pressing member 12 is parallel to the edge of the placement area 211.

As shown in connection with fig. 3-6, in some embodiments of the application, a compression module 100 includes a compression assembly 1 and a mounting base 2. Wherein the compressing assembly 1 comprises a moving member 11 and a compressing member 12, and the compressing member 12 is detachably assembled to the moving member 11 so as to replace the compressing member 12 of a different type. And the moving member 11 is mounted to the mounting base 2, wherein the mounting base 2 is mounted to the lower surface 22 of the carrying platform 20. It should be added that, in some embodiments, the fixing device 200 further includes at least one set of sliding assemblies 6, and the mounting base 2 is reciprocally mounted on the lower surface 22 through the sliding assemblies 6, that is, the mounting base 2 is indirectly mounted on the lower surface 22 of the carrying platform 20.

Referring to fig. 5 and 6, the compressing members 12 provided in the compressing module 100 are replaceable, and the types of the compressing members 12 may be divided into a dot-shaped compressing member 121 and a bar-shaped compressing member 122, wherein when the compressing member 12 is the dot-shaped compressing member 121, the single compressing member 12 includes a plurality of dot-shaped compressing portions, and when the compressing member 12 is the bar-shaped compressing member 122, the single compressing member 12 includes at least one bar-shaped compressing portion. I.e. the compression member 12 comprises one of a plurality of spot-like compression portions and at least one strip-like compression portion.

By replacing the pressing members 12 of different types, the fixing device 200 can be adapted to work pieces made of different materials. It should be noted that, for example, the work piece is a circuit board, and for the circuit board, the circuit board includes a hard circuit board and a flexible circuit board, wherein the flexible circuit board has excellent flexibility and bendability with respect to the hard circuit board, and it is also understood that the flexible circuit board is more easily deformed with respect to the hard circuit board.

For the hard circuit board, the pressing member 12 in the pressing module 100 may be selected to have a point-shaped pressing portion or a strip-shaped pressing portion (i.e. the point-shaped pressing member 121 or the strip-shaped pressing member 122 may be selected), but for the flexible circuit board, the pressing member 12 in the pressing module 100 may be selected to have only a strip-shaped pressing portion, so that the fixing device 200 may be applied to both the hard circuit board and the flexible circuit board by setting the pressing member 12 in the pressing module 100 as a replaceable member, so that the fixing device 200 has high versatility.

The pressing module 100 further includes a driving assembly for driving the moving member 11 to reciprocate relative to the assembling base 2 along the thickness direction of the carrying platform 20, so that the pressing member 12 assembled to the moving member 11 is lifted along the thickness direction of the carrying platform 20, and the pressing member 12 is used for pressing and fixing the workpiece to be processed on the upper surface 21 of the carrying platform 20. The driving assembly is further used for driving the assembly substrate 2 to drive the moving member 11 to reciprocate along the extending direction of the strip-shaped through hole 23, so as to drive the pressing module 100 to move relative to the carrying platform 20 along the extending direction of the strip-shaped through hole 23, so as to change the area of the pressing area, and the pressing module 100 in the fixing device 200 is suitable for pressing workpieces with different area sizes on the upper surface 21 of the carrying platform 20.

In some embodiments of the present application, the moving member 11 includes a plurality of assembling posts 111, and the assembling posts 111 pass through the bar-shaped through holes 23 to penetrate through the carrying platform 20, so that the pressing member 12 can be assembled on the top end of the assembling posts 111 from the side of the upper surface 21 of the carrying platform 20, so that the pressing member 12 is assembled on the moving member 11 and located on the side of the upper surface 21 of the carrying 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 carrying platform 20.

Referring to fig. 5 and 6, the compressing member 12 includes a plurality of dot-shaped compressing portions, each of which is assembled in one-to-one correspondence with each of the assembling posts 111, or alternatively, the compressing member 12 includes at least one bar-shaped compressing portion, and a single bar-shaped compressing portion is assembled in cooperation with a plurality of the assembling posts 111. For example, referring to fig. 5, fig. 5 shows a compression module 100 of the type having a plurality of dot-shaped compression parts, or referring to fig. 6, fig. 6 shows a compression module 100 of the type having two strip-shaped compression parts, of the compression member 12.

It should be noted that, when the compression module 100 is assembled on the carrying platform 20, each assembly post 111 disposed in the moving member 11 is respectively disposed through a bar-shaped through hole 23, and in the process that the compression module 100 moves along the extending direction of the bar-shaped through hole 23, the bar-shaped through hole 23 and the assembly post 111 play a guiding and matching role, so as to ensure the movement stability of the assembly post 111, and as the compression member 12 is assembled on the assembly post 111, the stability of the compression member 12 is improved.

Since the guide rail member 61 is arranged to extend in the extending direction of the bar-shaped through hole 23, the movement locus of the guide slider 62 during the movement along the guide rail member 61 coincides with the extending direction of the bar-shaped through hole 23, so that the movement locus of the fitting base 2 fixedly fitted with the guide slider 62 coincides with the extending direction of the bar-shaped through hole 23, so that the pressing module 100 is adapted to move in the extending direction of the bar-shaped through hole 23 with respect to the carrying platform 20.

It should be noted that, referring to fig. 5 and fig. 6, in some embodiments of the present application, a plurality of sets of sliding assemblies 6 are disposed in parallel in the compression module 100, and by disposing a plurality of sets of sliding assemblies 6, during the movement of the assembly substrate 2, the plurality of sliding assemblies 6 are mutually restrained, so as to reduce the risk of deflection of the assembly substrate 2, thereby effectively improving the movement stability of the assembly substrate 2, further making the movement track of the compression member 12 more accurate, and ensuring the movement accuracy of the compression member 12, so that the fixing device 200 has higher accuracy.

In one embodiment, referring to fig. 5 and 6, the first driver 3 may include a driving body 31 and a rod (not shown), where the driving body 31 is used to drive the rod to move along an axial direction of the rod. The driving body 31 is fixedly assembled on the assembling base 2, and one end of the rod body far away from the driving body 31 is connected with the moving member 11, so that the rod body is driven to move by the driving body 31, and the moving member 11 can move relative to the assembling base 2. It should be added that the axial direction of the rod body is parallel to the thickness direction of the carrying platform 20, so that the moving member 11 can reciprocate relative to the mounting base 2 in the thickness direction of the carrying platform 20. In this embodiment, taking the first driver 3 as an example of a lifting cylinder, the driving body 31 is a cylinder body of the lifting cylinder, and the rod body is a piston rod. The first actuator 3 may be a hydraulic lifter.

In this way, during the axial rotation of the screw rod 411 about the axial direction thereof, since the sliding fit piece 42 moves along the axial direction of the screw rod 411 and since the screw rod 411 is disposed along the extending direction of the bar-shaped through hole 23, the sliding fit piece 42 drives the assembly base 2 to move along the extending direction of the bar-shaped through hole 23, thereby achieving the effect that the compression module 100 moves along the extending direction of the bar-shaped through hole 23 with respect to the carrying platform 20.

It should be added that the driving manner of the screw 411 has advantages such as high positioning accuracy, stable movement, and small abrasion between the sliding fit piece 42 and the screw 411, so that the second driver 4 is composed of the screw motor 41 and the sliding fit piece 42, which not only enables the fixing device 200 to have high accuracy, but also facilitates the extension of the service life of the fixing device 200.
