[0023] See also Figure 1 and Figure 2 , surface treatment grinding equipment includes: A frame 10, wherein the frame 10 has a conveyor belt 11, and the conveyor belt 11 is provided with a feed end 11a and a discharge end 11b; The grinding assembly 20 includes a grinding wheel 21 and a back pressure wheel 22. The back pressure wheel 22 is arranged in alignment with the grinding wheel 21 and is located below the grinding wheel 21. The grinding wheel 21 and the back pressure wheel 22 are both rotatably arranged on the frame 10 and are located between the feed end 11a and the discharge end 11b. A lifting motion assembly 30, the lifting motion assembly 30 includes a lifting seat 31 and a lifting drive member 32, the lifting drive member 32 is fixedly disposed on the frame 10, and the lifting seat 31 is movably disposed on the frame 10 and connected to a lifting output shaft of the lifting seat 31; and An axial motion assembly 40, the axial motion assembly 40 comprises a moving seat 41 and an axial motion mechanism 42, the moving seat 41 is movably connected to the lifting seat 31, the moving end of the axial motion mechanism 42 is connected to the moving seat 41, and the connecting end of the grinding wheel 21 is connected to the moving seat 41; The lifting seat 31 is provided with a limiting hole, the output shaft of the grinding wheel 21 passes through the limiting hole and has a movable gap with the inner wall of the limiting hole, and the output shaft of the grinding wheel 21 is fixedly connected to the moving seat 41 .

[0024] In the technical solution of the present invention, the surface treatment grinding equipment can be used for surface grinding of structures such as circuit boards, lenses and grinding tools. The material to be processed passes through the feed end 11a of the conveyor belt 11 to reach the space between the grinding wheel 21 and the back pressure wheel 22 for surface grinding treatment. In order to ensure the uniformity of the thickness of the material to be processed, during the grinding process, the lifting motion component 30 and the axial motion component 40 can respectively drive or synchronously drive the grinding wheel 21 to move up and down close to or away from the back pressure wheel 22 and to move back and forth in a straight line along its own axial direction, thereby performing full-range grinding on the surface of the material to be processed to ensure the surface grinding quality of the material to be processed.

[0025] Specifically, the frame 10 includes a base body, a conveyor belt 11, a casing, a master control system and other structures, wherein the base body provides an installation base for the conveyor belt 11, and the conveyor belt 11 includes at least four drive rollers, which can be connected by transmission structures such as chains and belts, and realize synchronous movement under the drive of a motor; the casing is installed around the base body to achieve a protective effect; it can be understood that the master control system can control all electronic control devices of the surface treatment grinding equipment, and a human-computer interaction panel is provided on the outer surface of the casing. The user can issue corresponding instructions through the human-computer interaction panel, or input the required control program in advance, thereby realizing automatic surface grinding, such as inputting the plate thickness of the material to be processed in advance, and then the master control system can control the lifting height of the lifting drive 32 to make the grinding wheel 21 reach the required plate thickness position, thereby realizing surface grinding.

[0026] The grinding assembly 20 includes a grinding wheel 21 and a back pressure wheel 22. Both the grinding wheel 21 and the back pressure wheel 22 are rotatably arranged on the frame 10. Under the control of the driving member connected to them, they realize rotation along the axial direction. Specifically, the two ends of the rotating shaft of the grinding wheel 21 pass through the lifting seat 31 and the moving seat 41 to form two connecting ends. One connecting end is connected to the casing through a bearing, and the other connecting end is provided with a fixedly installed synchronous wheel. The synchronous wheel is connected to a servo motor through a toothed V-belt. In this way, under the control of the general control system, the servo motor can drive the grinding wheel 21 to rotate; the back pressure wheel 22 is connected to the driving roller of the conveyor belt 11 through a transmission structure such as a chain and a belt, thereby realizing synchronous transmission with the conveyor belt 11. When the material to be processed is transported between the grinding wheel 21 and the back pressure wheel 22, the back pressure wheel 22 can support the back side of the material to be processed so that the grinding wheel 21 can grind the surface to be processed of the material to be processed, thereby improving the grinding quality.

[0027] In order to achieve the height change and position change of the grinding wheel 21 along its own axis direction, under the control of the lifting motion component 30 and the axial motion component 40, the grinding wheel 21 can reach the required grinding position. Specifically, the lifting motion component 30 includes a lifting seat 31 and a lifting drive member 32. The lifting drive member 32 is fixedly arranged on the frame 10. The lifting drive member 32 is preferably a servo motor to ensure accuracy. A screw mechanism is provided on the output shaft of the servo motor. The lifting seat 31 is fixedly connected to the moving end of the screw mechanism. In this way, the height of the lifting seat 31 can be changed by driving the servo motor to rotate forward or reverse. At the same time, the moving seat 41 of the axial motion component 40 is connected to the lifting seat 31, and the output shaft of the grinding wheel 21 passes through the lifting seat 31 and is fixedly connected to the moving seat 41 through structures such as bearings. In this way, when the lifting drive member 32 is actuated, the lifting seat 31, the moving seat 41 and the grinding wheel 21 are lifted and lowered synchronously, thereby achieving height change. Further, in order to achieve the position change of the grinding wheel 21 along its own axis direction The axial motion component 40 has an axial motion mechanism 42, and the axial motion mechanism 42 has a moving end that can reciprocate along the axial direction of the grinding wheel 21. The moving end is fixedly connected to the moving seat 41. At the same time, the output shaft of the grinding wheel 21 is fixedly connected to the moving seat 41. In this way, when the axial motion component 40 is working, it can drive the grinding wheel 21 to make a linear reciprocating motion along its own axial direction, so that the surface to be processed of the material to be processed can be ground multiple times to improve the grinding quality. It can be understood that after the user inputs the thickness value of the material to be processed, the lifting motion component 30 can enter the working state to make the grinding wheel 21 reach the required grinding height. When the material to be processed is about to reach between the grinding wheel 21 and the pressed wheel, the axial motion component 40 can enter the working state to make the grinding wheel 21 make a linear reciprocating motion along its own axial direction. Of course, the relationship between the start time of the axial motion component 40 and the position of the material to be processed can be set by changing the design parameters of the master control system, which is not limited here.

[0028] See also Figure 2 and Figure 3 , the axial motion mechanism 42 comprises: An axial driving member 421, the axial driving member 421 is fixedly connected to the lifting seat 31; A transmission shaft 422, the transmission shaft 422 is disposed on the lifting seat 31, one end of the transmission shaft 422 is rotatably connected to the output end of the axial driving member 421, and the other end of the transmission shaft 422 is provided with an eccentric wheel 424; A first axial moving member 423, one end of which is connected to an eccentric wheel 424; and The second axial moving member 425 connects one end of the first axial moving member 423 away from the eccentric wheel 424 and the moving seat 41 .

[0029] Specifically, the axial driving member 421 is a servo motor, and a connecting plate is fixedly provided on the shell of the axial driving member 421, and the other end of the connecting plate is fixedly connected to the lifting seat 31, so as to realize synchronous lifting with the lifting seat 31; a transmission wheel is provided at the output end of the axial driving member 421, and another transmission wheel is provided at one end of the transmission shaft 422, and transmission is realized between the two transmission wheels through structures such as belts and chains. In this way, when the output end of the axial driving member 421 rotates, the transmission shaft 422 rotates synchronously; in order to convert the rotational motion of the axial driving member 421 into the linear motion of the grinding wheel 21, an eccentric wheel 424 is fixedly provided at one end of the transmission shaft 422 away from the axial driving member 421, and one end of the first axial moving member 423 is fixedly connected to the eccentric wheel 424 through structures such as bearings. At this time, the extension direction of the first axial moving member 423 is consistent with the axial direction of the grinding wheel 21, and the extension direction of the first axial moving member 423 is perpendicular to the extension direction of the transmission shaft 422. In this way, under the eccentric motion of the eccentric wheel 424, the first The moving end of the axial moving member 423 away from the transmission shaft 422 can move closer to or away from the axial driving member 421. At the same time, a second axial moving member 425 is fixedly provided at the moving end of the first axial movement, and the second axial moving member 425 is fixedly connected to the moving seat 41. In this way, when the axial driving member 421 rotates, the axial driving member 421 drives the transmission shaft 422 to rotate through structures such as belts and chains. The rotation of the transmission shaft 422 is converted into a linear reciprocating motion of the second axial moving member 425 through the eccentric wheel 424 and the first axial moving member 423, thereby driving the moving seat 41 to move closer to or away from the lifting seat 31 along the axial direction of the grinding wheel 21. The moving seat 41 is fixedly connected to the output shaft of the grinding wheel 21. Therefore, when the moving seat 41 performs a linear reciprocating motion, it can synchronously drive the grinding wheel 21 to move, because the output shaft of the grinding wheel 21 and the limiting hole of the lifting seat 31 have an active gap. At this time, the grinding wheel 21 will not drive the lifting seat 31 to move synchronously when performing a linear reciprocating motion, thereby reducing the load of the moving seat 41.

[0030] In one embodiment of the present invention, see Figure 3 and Figure 4 The lifting seat 31 includes a first connecting plate 311, a second connecting plate 312 and a third connecting plate 313. The second connecting plate 312 and the third connecting plate 313 are arranged at both ends of the first connecting plate 311 and are both located on the side of the first connecting plate 311 facing away from the frame 10; wherein, the first connecting plate 311 is provided with a limiting hole, the second connecting plate 312 is connected to the lifting output shaft of the lifting drive member 32, and the third connecting plate 313 is provided with two limiting blocks 314 on the side facing the transmission shaft 422, and a limiting block 314 is fixedly passed through each end of the transmission shaft 422.

[0031] In this embodiment, the lifting seat 31 includes a first connecting plate 311, a second connecting plate 312 and a third connecting plate 313. The first connecting plate 311 can be movably connected to the frame 10 through structures such as guide rails and linear moving modules. The second connecting plate 312 arranged below the first connecting plate 311 is fixedly connected to the lifting output shaft of the lifting drive member 32. At this time, the lifting output shaft is an extended structure connected to the output shaft of the lifting drive member 32. Specifically, the lifting drive member 32 is placed flat on the bottom of the frame 10, and a gear is provided at its output end. The gear meshes with the first bevel gear. At the same time, the conical surface of the first bevel gear abuts against the conical surface of the second bevel gear, and a screw rod is inserted in the center of the second bevel gear. The lifting output shaft of the mechanism is extended in the vertical direction and connected to the second connecting plate 312. In this way, the output shaft of the lifting drive member 32 is prevented from directly bearing the load of the lifting motion component 30 and the axial motion component 40 through structural change, and deformation and other problems are prevented from occurring on the output shaft of the lifting drive member 32. In order to realize the rotation constraint of the transmission shaft 422, two limit blocks 314 are provided on the side of the third connecting plate 313 facing the transmission shaft 422, and a limit block 314 is fixedly provided at both ends of the transmission shaft 422. In this way, the transmission shaft 422 will not deviate from its position while rotating on the lifting seat 31, thereby avoiding the second axial motion member 425 from moving in a biased direction.

[0032] For further information, see Figure 4 In order to save installation space, the first connecting plate 311, the second connecting plate 312 and the third connecting plate 313 are enclosed to form an installation cavity, and the movable seat 41 is located in the installation cavity. Specifically, the first connecting plate 311, the second connecting plate 312 and the third connecting plate 313 are enclosed to form a lifting seat 31 with an opening on one side, and the movable seat 41 can be placed in the installation cavity through the opening. At the same time, the movable seat 41 is connected to the third connecting plate 313 through the second axial moving part 425, and there is a moving gap between the movable seat 41 and the first connecting plate 311. In this way, when the movable seat 41 realizes linear reciprocating motion, it will not fall on the second connecting plate 312.

[0033] In one embodiment of the present invention, see Figure 3 A directional slider 315 is also provided on the side of the third connecting plate 313 facing the transmission shaft 422, and a directional slide rail 411 is provided on the side of the moving seat 41 facing the third connecting plate 313. The directional slider 315 is slidably connected to the directional slide rail 411. In this way, when the moving seat 41 drives the grinding wheel 21 to move, the restraining effect between the directional slide rail 411 and the directional slider 315 can avoid the skew movement caused by excessive load on the moving seat 41.

[0034] In one embodiment of the present invention, see Figure 1The surface treatment grinding equipment also includes a spray head 60, which is fixed to the frame 10 and located above the grinding wheel 21. The spray head 60 is arranged to be inclined toward the grinding wheel 21. Specifically, the spray head 60 can be connected to a water pump and other structures through a water pipe, so as to remove dust and cool the product being ground. At the same time, in order to avoid dust and water vapor splashing, a protective cover is provided around the grinding wheel 21. The protective cover is provided on the grinding wheel 21, the back pressure wheel 22 and the spray head 60 to achieve isolation treatment.

[0035] In one embodiment of the present invention, see Figure 6 The conveyor belt 11 includes a first conveying section 111 and a second conveying section 112 of synchronous transmission, the first conveying section 111 and the second conveying section 112 are arranged at intervals, and the back pressure wheel 22 is located between the first conveying section 111 and the second conveying section 112; the grinding assembly 20 also includes a first pressing wheel 23 and a second pressing wheel 24, the first pressing wheel 23 is movably arranged above the tail of the first conveying section 111 and close to the back pressure wheel 22, and the second pressing wheel 24 is movably arranged above the head of the second conveying section 112 and close to the back pressure wheel 22; The feeding end 11 a is located at the head of the first conveying section 111 , and the discharging end 11 b is located at the tail of the second conveying section 112 .

[0036] In this embodiment, in order to prevent the material to be processed from being deviated from its position due to the grinding force, water flow impact, etc. during the grinding process, a pressing wheel is provided on both sides of the back pressure wheel 22. Specifically, the conveyor belt 11 includes a first conveying section 111 and a second conveying section 112 of synchronous transmission. The first conveying section 111 and the second conveying section 112 are arranged at intervals. The back pressure wheel 22 is located between the first conveying section 111 and the second conveying section 112. A first pressing wheel 23 is provided above the tail of the first conveying section 111 and close to the back pressure wheel 22. A second pressing wheel 24 is provided above the head of the second conveying section 112 and close to the back pressure wheel 22. The first pressing wheel 23 and the second pressing wheel 24 can apply a force to the material to be processed in the vertical direction toward the conveyor belt 11. In this way, the problem of easy slipping caused by reducing the friction between the material to be processed and the conveyor belt 11 due to water stains on the conveyor belt 11 is avoided.

[0037] In one embodiment, see Figure 5The frame 10 is provided with two elastic mechanisms 50, each elastic mechanism 50 includes a pressing adjustment rod 51 and an elastic telescopic member 52 fixedly arranged on the frame 10, one end of the pressing adjustment rod 51 is connected to the elastic telescopic member 52, wherein one pressing adjustment rod 51 is tilted toward the first pressing wheel 23 and connected to the first pressing wheel 23, and the other pressing adjustment rod 51 is tilted toward the second pressing wheel 24 and connected to the second pressing wheel 24. Specifically, the elastic telescopic member 52 includes a fixed section and a telescopic end, the fixed section is fixed to the frame 10 by a locking structure such as a screw, a fixing plate and the like, the telescopic end is movably inserted in the fixed section and connected by an elastic member such as a spring or a rubber plunger, one end of the pressing adjustment rod 51 is connected to the telescopic end, and the other end is connected to the pressing wheel, so that under the elastic force adjustment of the elastic mechanism 50, the force applied to the material to be processed can be adaptively adjusted, thereby ensuring the transmission efficiency, and at the same time, each pressing adjustment rod 51 is tilted to avoid applying a vertical downward pressure directly to the material to be processed, thereby preventing the material from being deformed or even damaged.

[0038] In one embodiment of the present invention, see Figure 6 The frame 10 is rotatably provided with a plurality of auxiliary transport wheels 13, the auxiliary transport wheels 13 are located above the conveyor belt 11, and a material passing gap is provided between the auxiliary transport wheels 13 and the conveyor belt 11. It can be understood that the frame 10 will form a raised limiting structure on both sides of the conveyor belt 11, and the auxiliary transport wheels 13 are rotatably provided on the raised limiting structure. In this way, when the material is in and out, the pressing effect of the auxiliary transport wheels 13 can prevent the material from slipping due to water stains on the conveyor belt 11.

[0039] In one embodiment of the present invention, see Figure 6 The surface treatment grinding equipment also includes an over-material counter 14, which is arranged on the frame 10 and located at the feeding end 11a and the discharging end 11b of the conveyor belt 11, so as to avoid the problem of empty material. It can be understood that the over-material counter 14 can be a photoelectric sensor, an electromagnetic sensor or other device. When the material passes through the detection area of ​​the over-material counter 14, the counter will detect the passage of the material and record the quantity, so as to facilitate the verification of the material quantity and be recorded by the master control system, which is convenient for production management.
