Abstract
Description
Technical Field
[0001] This utility model relates to the field of industrial production equipment technology, and in particular to an automatic sandblasting machine. Background Technology
[0002] In industrial production, many products require surface finishing, such as mobile phone cases, tablet cases, and laptop cases, which need sandblasting to achieve different colors and surface effects. Traditional sandblasting machines generally use a "workpiece conveying / oscillating sandblasting synchronization" method, creating numerous "W"-shaped patterns on the sandblasted surface, resulting in noticeable missed and repeated blasting areas. Therefore, traditional methods typically use a large number of spray guns for repeated sandblasting to achieve a relatively uniform surface effect. However, this not only wastes a lot of compressed air and abrasive, resulting in high costs, low efficiency, and long processing time, but also easily causes product deformation. In addition, existing sandblasting machines of this type usually have a complex structure, and the spray guns cannot easily and flexibly move automatically in three dimensions, requiring the workpiece to move in coordination, which also affects the sandblasting accuracy. Furthermore, the lack of obstruction between the spray gun and the moving mechanism (motor, screw, slide, etc.) means that the sprayed material may stick to the moving mechanism, potentially causing damage over time. For example, the automatic sandblasting machine for a coating machine baffle disclosed in Chinese Utility Model Patent CN202223185182.3 suffers from the above problems. Utility Model Content
[0003] This utility model addresses the shortcomings of existing technologies by providing a high-efficiency and energy-saving automatic sandblasting machine with a simpler structure, higher sandblasting efficiency and precision, more uniform sandblasting, and protective effect on the moving mechanism.

[0005] Furthermore, an X-axis motor and a lifting motor are installed on the X-axis moving base. The lifting motor drives the lifting rod to move up and down, and the X-axis motor drives the X-axis moving base to move horizontally along the X-axis mechanism. A Y-axis motor is installed on the Y-axis moving base, and the Y-axis motor drives the Y-axis moving base to carry the X-axis mechanism to move horizontally along the Y-axis mechanism.
[0006] Furthermore, both the X-axis mechanism and the Y-axis mechanism adopt a strip-shaped square beam, with X-axis slide rails provided on its top and side surfaces, and the X-axis moving seat is movably mounted on the X-axis slide rail; the Y-axis mechanism is provided with a Y-axis slide rail, and the Y-axis moving seat is movably mounted on the Y-axis slide rail.

[0008] Furthermore, the partition is horizontally installed on the bottom surface of the Y-axis mechanism, the sealing gasket covers the clearance hole of the partition, the edge of the sealing gasket is sealed to the partition, and the lifting rod passes through the middle of the sealing gasket.
[0009] Preferably, the sealing gasket is made of a rubber material, such as silicone.
[0010] Preferably, the X-axis moving base includes two units, each of which is equipped with at least one lifting rod. A fixed bracket is installed together at the lower part of each lifting rod, and several spray guns are fixedly mounted through the fixed bracket.
[0011] This invention utilizes a three-dimensional moving mechanism, primarily composed of an X-axis mechanism, a Y-axis mechanism, a lifting rod, and corresponding motors, to mount the spray gun. This allows the spray gun to precisely move and sandblast a stationary workpiece along a pre-programmed path. The design is not only simpler but also faster, more energy-efficient, more precise, more flexible in control, and provides better sandblasting uniformity. Furthermore, by incorporating partitions and sealing gaskets, the invention effectively prevents paint mist generated during sandblasting from adhering to the motor, track, rack, and other moving mechanisms without affecting the movement of the lifting rod, thus protecting the moving mechanism.

Specific implementation mode
[0016] In this embodiment, referring to Figure 1 and Figure 2 , the high-efficiency energy-saving automatic sandblasting machine includes a three-dimensional (X-Y-Z) moving mechanism and a spray gun 1. The spray gun 1 is installed on the three-dimensional moving mechanism to achieve movement; the three-dimensional moving mechanism includes an X-axis mechanism 3, a Y-axis mechanism 5 and a lifting rod 22 that are perpendicular to each other in a three-dimensional space. Two parallel Y-axis mechanisms 5 are fixedly installed in the body of the sandblasting machine, so that the whole device forms a hanging structure, and the workpiece is fixed below for sandblasting; the X-axis mechanism 3 is erected on the Y-axis mechanism 5 through two Y-axis moving seats 4 so as to move along the Y-axis; an X-axis moving seat 2 that can move along the X-axis is provided on the X-axis mechanism 3, and the lifting rod 22 is movably installed on the X-axis moving seat 2 so as to perform lifting movement, and the spray gun 1 is installed at the lower part of the lifting rod 22; a partition board 6 is provided between the spray gun 1 and the Y-axis mechanism 5. The middle of the partition board 6 is a hollow structure to form an avoidance hole 61. An elastic stretchable sealing gasket (not shown) is provided in the avoidance hole 61. The sealing gasket is hermetically connected to both the lifting rod 22 and the partition board 6, and the structure and function are similar to the gear shift leather sleeve on an automobile gearbox; this can neither affect the lifting movement nor block the paint mist formed during sandblasting.
[0017] An X-axis motor 21 and a lifting motor (blocked inside) are provided on the X-axis moving seat 2. The lifting rod 22 is driven by the lifting motor to perform lifting movement, and the X-axis moving seat 2 is driven by the X-axis motor 21 to move horizontally along the X-axis mechanism 3; a Y-axis motor 41 is provided on the Y-axis moving seat 4. The Y-axis moving seat 4 is driven by the Y-axis motor 41 to carry the X-axis mechanism 3 to move horizontally along the Y-axis mechanism 5. In this way, the spray gun 1 can be conveniently and flexibly moved in a three-dimensional space according to the path trajectory set by the program. For example, Figure 3 and Figure 4 The two shown are two typical movement trajectories, and the path can be edited by a computer in a path document. Of course, this three-dimensional moving structure can be directly realized by the prior art.
[0018] Both the X-axis mechanism 3 and the Y-axis mechanism 5 adopt strip-shaped square beams, which can be aluminum profiles. X-axis slide rails 31 are provided on their top and side surfaces, and the X-axis moving seat 2 is movably mounted on the X-axis slide rails 31. Y-axis slide rails 51 are provided on the Y-axis mechanism 5, and the Y-axis moving seat 4 is movably mounted on the Y-axis slide rails 51.
[0019] An X-axis rack 32 is provided on the X-axis mechanism 3, and the X-axis motor 21 is connected to the X-axis rack 32 through a gear (not shown). A Y-axis rack 52 is provided on each of the two Y-axis mechanisms 5, and the Y-axis motor 41 is connected to the Y-axis rack 52 through a gear (not shown). Horizontal movement on the rack is achieved by driving the gears to rotate via the motors, as described in patent CN202223185182.3.
[0020] The partition 6 is horizontally installed on the bottom surface of the Y-axis mechanism 5. The sealing gasket covers the clearance hole 61 of the partition 6, and the edge of the sealing gasket is sealed to the partition 6. The lifting rod 22 passes through the middle of the sealing gasket.
[0021] The sealing gasket can be made of rubber materials, such as silicone.
[0022] The X-axis moving base 2 includes two units, each of which is equipped with at least one lifting rod 22. A fixed bracket 23 is installed together at the lower part of each lifting rod 22. Several spray guns 1 are fixed by the fixed bracket 23, so that multiple spray guns can perform sandblasting operations at the same time.
[0023] The table below compares the working parameters of this utility model with those of a traditional sandblasting machine:

[0025] As shown in the table above, this invention can achieve or even surpass the performance of traditional sandblasting machines while significantly reducing the number of spray guns. For example, 8 spray guns can achieve the sandblasting efficiency of 16-20 traditional guns, which is 200% of the efficiency of traditional sandblasting machines. This can save 50-60% of electricity consumption and 60-70% of blasting consumables. Furthermore, with the cooperation of computer programs, it can precisely guide and effectively blast sand, avoiding repeated blasting, missed blasting, and ineffective blasting that deviates from the target.

The above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of this application should still fall within the scope of the present invention.
