DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] The object of the present invention is to provide an angle adjustment device to solve the problems existing in the above-mentioned prior art, which can realize the angle adjustment of materials with high adjustment accuracy and avoid curling and piling of materials.

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] like Figure 1-5As shown, the present invention provides an angle adjustment device, including a vacuum negative pressure workbench 2, an angle adjustment table 3 and a push rod assembly 4. The material to be integrated is placed on the vacuum negative pressure workbench 2, the angle adjustment table 3 is slidably arranged on the top surface of the vacuum negative pressure workbench 3 and is located on the side of the material to be integrated, and the push rod assembly 4 is used to push the material to be integrated to make it horizontal; the vacuum negative pressure workbench 3 is arranged on a frame 1, and a foot 11 is installed on the bottom side of the frame 1, and the foot 11 is a fixed foot or a roller foot.

[0026] The material to be adjusted is placed on a vacuum negative pressure workbench 2, which provides vacuum negative pressure for the material so that the material can be tightly attached to the workbench. The push rod mechanism 4 pushes the material to one side of the workbench, and then starts the angle adjustment table 3 to adjust the angle of the material. While adjusting the angle of the material and ensuring the adjustment accuracy, it can also avoid curling and piling of the material.

[0027] In order to prevent the material from curling, the vacuum negative pressure workbench 2 includes a workbench and a hollow chamber. The workbench for placing the material to be integrated is integrally arranged on the top of the hollow chamber. A number of air holes are evenly opened on the workbench. The hollow chamber is connected to the vacuum pump through a pipeline. The vacuum pump evacuates the hollow chamber, so that the workbench with air holes is in a vacuum negative pressure state, and the material to be integrated is sucked tightly on the workbench, ensuring that all corners and edges of the material are adsorbed on the workbench.

[0028] For the integration of materials, gapless assembly is first performed. Specifically, the push rod mechanism 4 includes an electric cylinder 42 driven by a motor 41, a guide shaft 45 and a push rod 46. A vertical plate 43 for supporting and fixing the electric cylinder 42 and the guide shaft 45 is provided on the vacuum negative pressure workbench 2. The guide shaft 45 is fixed to the vertical plate 43 through a bearing 44. The electric cylinder 42 and the guide shaft 45 are arranged in parallel and the ends of both are fixedly connected to the push rod 46. A spring steel sheet 47 for contacting the material is installed on the outer side of the push rod 46. The guide shaft 45 and the electric cylinder 42 cooperate so that the push rod 46 can horizontally push multiple materials to one side of the workbench without gaps. Under the premise of zero gaps between multiple materials, the angle is adjusted.

[0029] Belt drive group 1 and belt drive group 2 are installed on both sides of the vacuum negative pressure workbench 2 to drive the left angle adjustment platform and the right angle adjustment platform respectively; belt drive group 1 includes two groups of driving wheels and driven wheels symmetrically installed on both sides of the vacuum negative pressure workbench 2, and the driving wheel driven by the motor is connected to the driven wheel through the belt 12. A vertical support column 31 is fixedly connected to the belt 12, and the vertical support columns 31 on the belts 12 on both sides are symmetrically arranged. The vertical support columns 31 are used to support the left angle adjustment platform to move with the belt; the belt drive group 2 has the same structure as the belt drive group 1, and the belt drive group 2 is used to support and drive the right angle adjustment platform to move. Among them, the driving mode of the angle adjustment platform 3 is not limited, and other driving forms can be adopted according to actual use conditions, as long as the corresponding movement requirements can be met.

[0030] The vertical support column 31 includes a fixed block 311, a column 312 and a clamping block 313 fixed in sequence from top to bottom. The fixed block 311 is fixedly connected to the angle adjustment platform 3. The clamping block 313 includes an upper clamping block and a lower clamping block fastened by bolts. The belt 12 is clamped between the upper clamping block and the lower clamping block. The lower surface of the upper clamping block and the upper surface of the lower clamping block are toothed or wavy contact surfaces, ensuring that there is sufficient friction between the support column and the belt 12, thereby driving the angle adjustment platform 3 to move through the support column.

[0031] The angle adjustment equipment of the present invention, the angle adjustment table 3 can adjust the angle of multiple materials within a range of greater than 0° and less than 180°, meeting the requirements of different material assembly angles, specifically: the angle adjustment table 3 is composed of a left angle adjustment table and a right angle adjustment table, the sliding range of the left angle adjustment table is to slide to the right from the left side of the vacuum negative pressure workbench 2, and the sliding range of the right angle adjustment table is to slide to the left from the right side of the vacuum negative pressure workbench 2; a plurality of positioning holes 32 are provided on the angle adjustment platform 2, specifically, a plurality of rows of positioning holes 1 are provided on the left angle adjustment table at an angle tilted, and a plurality of rows of positioning holes 2 are provided on the right angle adjustment table at an angle tilted, and the corresponding inclination angles of the positioning holes 1 and the positioning holes 2 are complementary to each other; a positioning pin is spirally installed in each positioning hole 32, and the positioning pin is used to adjust the inclination angle of the material.

[0032] The two angle adjustment platforms 3 have two action modes:

[0033] One is that the two angle adjustment platforms 3 move synchronously, and the left angle adjustment platform and the right angle adjustment platform move synchronously toward the material from the left and right sides of the material to be integrated respectively. The angle adjustment platforms 3 on the left and right sides provide two benchmarks for the angle adjustment of the material. When the angle adjustment platforms 3 on both sides are in contact with the material, the material angle is adjusted in place, and the two angle adjustment platforms 3 stop moving. The overall angle adjustment process is short in time and efficient, and can improve the integration accuracy.

[0034] Furthermore, another working mode is: the action selection sequence of the two angle adjustment platforms 3 is different, the angle adjustment platform 3 on one side moves first, and there is a time difference in the starting time of the action of the two angle adjustment platforms 3. When the angle adjustment platform 3 on one side moves into place, one side of the material is integrated and aligned, and then the angle adjustment platform 3 on the other side moves into place again to integrate and align the material again. The order in which the two angle adjustment platforms 3 move in succession is coordinated with the positioning holes on both sides that are inclined at complementary angles to each other, so that there are two benchmarks in the integration process of the material. The angle adjustment platform 3 of the previous action and the inclined positioning hole 1 are used as the preliminary integration benchmark, and the angle adjustment platform 3 of the latter action are accurately integrated with the positioning hole 2 benchmark (the inclination direction of positioning hole 1 and positioning hole 2 is the same, and the horizontal right side is used as the benchmark, and the inclination angles of the oblique lines where positioning hole 1 and positioning hole 2 are located are complementary angles), which can effectively reduce the angle tolerance value and improve the integration accuracy.

[0035] The above two working modes of the angle adjustment table 3 can be appropriately selected according to the needs of the specific production and processing process, and its working mode is not limited.

[0036] The positioning pin includes a bolt 322 and a push piece 323. The bolt 322 is threadedly screwed into the positioning hole 32. The bottom of the bolt 322 is fixedly connected with a push piece 323 for pushing the material. The push piece 323 is arranged parallel to the side of the material. The nut of the bolt 322 is symmetrically provided with two threaded holes 321. The angle adjustment platform 3 is provided with an auxiliary hole 33 corresponding to the threaded hole 321. The threaded hole 321 and the auxiliary hole 33 are fixedly connected by a screw. The setting of the auxiliary hole 33 can prevent the angle of the push piece 323 from being deflected when the bolt 322 rotates, thereby affecting the angle adjustment of the material. The auxiliary hole 33 and the threaded hole 321 are fixed to play a secondary positioning role for the positioning pin.

[0037] The angle adjustment device is provided with angle adjustment platforms 3 on both sides of the material. The sequential setting of the two angle adjustment platforms 3 and the positioning holes 32 on both sides inclined at complementary angles are matched, so that there are two benchmarks in the integration process of the material, which can effectively reduce the angle tolerance value and improve the integration accuracy.

[0038] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
