The embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0046] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0047] Example:

[0048] like Figure 1-9 As shown, this embodiment provides a modular sanding belt machine dedicated to robot grinding, including a frame 1, a drive assembly 2, a deviation correction assembly 3, a motor device 4, a pulley 5 and a belt body 6;

[0049] The driving assembly 2 includes a driving beam 201, an auxiliary wheel 202 and a driving wheel 203. The driving beam 201 is arranged on the frame 1, and the auxiliary wheel 202 and the driving wheel 203 are arranged on the driving beam 201;

[0050] The deflection correction component 3 is provided on the driving beam 201 and has a deflection correction wheel 301 that can move relative to the length direction of the driving beam 201;

[0051] The pulley 5 is provided at the driving end of the motor device 4, and the belt body 6 is sleeved on the pulley 5 and the driving wheel 203;

[0052] The abrasive belt body 7 is sleeved on the auxiliary wheel 202 , the deviation-correcting wheel 301 and the driving wheel 203 .

[0053] The modular sanding belt machine dedicated to robot polishing in this embodiment has a correction component 3 that can adjust the position of the correction wheel 301 relative to the drive component 2, so as to meet different polishing process requirements. In addition, the number of modular sanding belt machines in this embodiment can be used in combination. Specifically, two modular sanding belt machines are symmetrically arranged on the left and right to form a workstation for polishing. The sanding belt body 7 and the auxiliary wheel 202 and the driving wheel 203 on each modular sanding belt machine can also be made of different materials and sizes to realize polishing with different consumables and processes, thereby reducing the problems of high cost, large number and excessive space occupied by different equipment previously used.

[0054] In this embodiment, there are two driving components 2 which are relatively arranged one above the other on the frame 1 , namely an upper driving component 2 and a lower driving component 2 . Each driving component 2 is provided on a deviation correcting component 3 .

[0055] Regarding the above structure, in this embodiment, see Figure 7 , there are two symmetrically arranged modular belt sanders for robot grinding, and the industrial robot is set between the two modular belt sanders for robot grinding:

[0056] In the modular belt sander for robot polishing on the left, the upper drive assembly 2 has a left A01 station, a left A02 station, and a left A03 station, one end of which is connected to the driving wheel 203; the lower drive assembly 2 has a left B01 station, a left B02 station, and a left B03 station, one end of which is connected to the driving wheel 203;

[0057] In the modular belt sander dedicated to robot polishing on the right side, the upper drive assembly 2 has a right A01 station, a right A02 station, and a right A03 station, one end of which is connected to the driving wheel 203; the lower drive assembly 2 has a right B01 station, a right B02 station, and a right B03 station, one end of which is connected to the driving wheel 203;

[0058] Through the above structure, grinding with different consumables can be achieved. Therefore, the same belt sander can achieve belt sanding with different wheel diameters (selecting different auxiliary wheels 202 and driving wheels 203) and grinding with different consumables (selecting different belt bodies 7).

[0059] There are two ways to drive the driving wheel 203 in this embodiment:

[0060] See also Figures 1 to 3The first type: the number of motor devices 4 is one, the driving beam 201 is provided with a fixed block 2011 for connecting to the frame 1, the motor device 4 is provided with a motor mounting plate 401 for connecting to the frame 1, the pulley 5 is provided with two belt mounting positions 501, the number of belt bodies 6 is two, namely an upper belt body and a lower belt body, the upper belt body is sleeved on one belt mounting position 501 and the driving pulley 203 of the upper drive assembly 2, and the upper belt body is sleeved on the other belt mounting position 501 and the driving pulley 203 of the lower drive assembly 2.

[0061] In the above structure, the pulley 5 is driven to rotate by a motor device 4. At the same time, the pulley 5 has two belt mounting positions 501 that can act on the upper belt body and the lower belt body to realize the rotation of the upper drive component 2 and the lower drive component 2. At the same time, a sheet metal cover can be set to seal the pulley 5, the upper belt body and the lower belt body to avoid the influence of dust during the grinding process.

[0062] See also Figure 8 , the second type: the number of motor devices 4 is two, which are respectively provided in the upper drive component 2 and the lower drive component 2;

[0063] A slider 2012 is provided on the driving beam 201 , a track member 2013 slidably matched with the slider 2012 is provided on the frame 1 , and a motor mounting plate 401 for connecting to the driving beam 201 is provided on the motor device 4 .

[0064] See also Figure 9 Specifically, it also includes a floating adjustment mechanism 8, which includes a floating adjustment cylinder 801, a nylon block 802, a limit block 803 and a limit plate 804. The limit block 803 and the floating adjustment cylinder 801 are arranged on the frame 1, and the limit plate 804 is arranged on the driving beam 201. The limit block 803 is provided with a limit groove 8031 that cooperates with the limit plate 804. The nylon block 802 is arranged between the limit plate 804 and the floating adjustment cylinder 801, and the nylon block 802 is connected to the driving end of the floating adjustment cylinder 801.

[0065] In the above structure, the upper drive assembly 2 and the lower drive assembly 2 drive the driving wheel 203 in a separate driving manner, and also have a floating adjustment function. The floating adjustment cylinder 801 can cause the upper drive assembly 2 and the lower drive assembly 2 to slide relative to the frame 1, realizing the adjustment of the belt sander from a fixed to a floating position. Compared with the first fixed structure described above, the floating effect is mainly achieved by the floating adjustment cylinder 801 in conjunction with the track member 2013. At the same time, a precision pressure regulating valve can be provided to adjust the floating adjustment cylinder 801 to adjust the floating force. When the floating adjustment cylinder 801 is ventilated, the floating adjustment cylinder 801 acts on the limit plate 804 through the nylon block 802 to realize the movement of the drive assembly 2. When the front end of the drive assembly 2 is subjected to a force greater than the thrust of the floating adjustment cylinder 801, the floating adjustment cylinder 801 will compress and the drive assembly 2 will retreat as a whole until the internal pressure of the floating adjustment cylinder 801 is balanced with the external force, thereby achieving the floating effect of grinding.

[0066] Specifically, a cantilever bracket 2014 is provided on the driving beam 201 , and the auxiliary wheel 202 is provided on the cantilever bracket 2014 .

[0067] See also Figures 4 to 6 The specific structure of the correction component 3 of this embodiment is as follows:

[0070] The transition plate 305 is provided between the driving end of the guide cylinder 302 and the mounting bracket 303. The transition plate 305 is provided with an elongated hole 3051. A connecting bolt 3052 is provided in the elongated hole 3051. One end of the connecting bolt 3052 is threadedly engaged with the mounting bracket 303.

[0071] The first deviation correction adjustment mechanism includes a first adjustment block 306 and a first adjustment bolt 307. The first adjustment block 306 is provided at both ends of the transition plate 305. The first adjustment bolt 307 is threadedly engaged with the first adjustment block 306. One end of the first adjustment bolt 307 abuts against the mounting bracket 303.

[0072] The mounting bracket 303 has a first mounting portion 3031 and a second mounting portion 3032. The correcting wheel 301 is provided with a first mounting shaft 3011 and a second mounting shaft 3012. The first mounting shaft 3011 is in sliding engagement with the first mounting portion 3031, and the second mounting shaft 3012 is in sliding engagement with the second mounting portion 3032. The first mounting portion 3031 is provided with a shoulder screw 3013 connected to the first mounting shaft 3011.

[0073] The second correction adjustment mechanism includes a second adjustment block 308, a third adjustment block 309, a second adjustment bolt 310 and a third adjustment bolt 311. The second correction adjustment mechanism is arranged on the second mounting part 3032. The second adjustment block 308 and the third adjustment block 309 are respectively arranged on both sides of the second mounting shaft 3012. The second adjustment bolt 310 is threadedly engaged with the second adjustment block 308, and one end of the second adjustment bolt 310 is in contact with the second mounting shaft 3012. The third adjustment bolt 311 is threadedly engaged with the third adjustment block 309, and one end of the third adjustment bolt 311 is in contact with the second mounting shaft 3012.

[0074] Specifically, a sanding belt breakage sensor 312 is provided on the transition plate 305 .

[0075] In the above structure, through the first correction adjustment mechanism and in conjunction with the long hole 3051 structure of the transition plate 305, the relative position of the mounting bracket 303 and the transition plate 305 can be adjusted to meet the changes in the width of the sanding belt caused by different user needs. Through the second correction adjustment mechanism, the correction wheel 301 can be rotated and adjusted relative to the shoulder screw 3013 to meet the correction of the sanding belt.

[0076] At the same time, a bearing assembly is provided at the connection between the auxiliary wheel 202, the driving wheel 203 and the driving beam 201 of this embodiment, and a cover or a pressure cover is provided at the bearing assembly for sealing protection to meet the dust-proof requirements in the grinding environment.

When designing parts and structures, the versatility and rationality are taken into consideration. The same parts are used to assemble a bilaterally symmetrical sanding machine to solve the problem of space utilization. At the same time, one motor can be used to drive multiple sets of driving wheels 203, and modular design and universal design can be used to achieve fixed and floating sharing, thereby solving the equipment cost problem.

[0078] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Therefore, any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
