Description

Technical Field

[0001] The invention relates to the technical field of hard and brittle bar processing, in particular to a grinding machine. Background Art

[0002] In the prior art, the traditional processing methods for squaring, grinding and rounding of hard and brittle bars at home and abroad are three separate processes, that is, three different equipments are used to complete the whole processing of single crystal silicon bars. In actual operation, the wire squarer usually needs to use adhesive to square the hard and brittle bars at the same time, and then the squared hard and brittle bars are separately rounded by the cylindrical grinder, and finally sent to the surface grinder for surface grinding and polishing.

[0003] More information related to the above technical solution can also be found in the following documents:

[0004] In the Chinese utility model patent with the authorization publication number CN 206578672U, a fully automatic single crystal silicon grinding and rounding machine processing equipment is disclosed. The fully automatic single crystal silicon grinding and rounding machine processing equipment includes a base frame, a cutting and grinding workbench, a centering device, a rough grinding power head, a fine grinding power head, and a size detection unit. The utility model enables the grinding and rounding of the crystal rod to be fully automatically performed in one device, without the need for transfer between different devices, which can effectively shorten the process of crystal rod circulation; at the same time, the grinding power head adopts a symmetrical layout, and performs double-sided processing at the same time, which doubles the processing efficiency.

[0005] In the Chinese utility model patent with authorization publication number CN 212528283U, the utility model relates to an annular wire saw cutting operating mechanism, including a frame, an annular wire saw cutting unit and a lifting unit; the annular wire saw cutting unit includes a wire saw cutting assembly and a linkage frame, wherein the wire saw cutting assembly includes a main drive assembly, a tensioning assembly and an annular cutting wire, the main drive assembly includes a main drive motor and a main drive wheel, the main drive wheel is transmission-connected to the main drive motor, the tensioning assembly includes a tensioning wheel, a tensioning spindle, a tensioning bearing seat, a swing arm, a swing arm rotating shaft, a swing arm bearing seat, a tension arm and a tensioning motor, the tensioning wheel is sleeved on the side wall of the tensioning bearing seat, the tensioning bearing seat is sleeved outside the tensioning spindle, one end of the swing arm is fixed to the tensioning spindle, and the other end is fixed to the swing arm rotating shaft, the swing arm bearing seat is sleeved outside the swing arm rotating shaft, and the tensioning motor is connected to the swing arm rotating shaft through the tension arm.

[0006] In the process of implementing the present invention, the inventors found that the prior art has the following problems:

[0007] The existing feeding mechanism cannot ensure that the center position of the hard and brittle bar in the length direction is located at the specified position of the clamping assembly. When it comes to hard and brittle bars of different lengths, the subsequent clamping device cannot clamp the hard and brittle bar. One end of the hard and brittle bar may exceed the clamping range of the clamping device, while the other end is within the clamping range of the clamping device, which makes it inconvenient to use the clamping device. Summary of the invention

[0008] Therefore, it is necessary to provide a grinder to solve the technical problem that the existing feeding mechanism cannot ensure that the center position of the hard and brittle rod in the length direction is located at the specified position of the clamping assembly, which is inconvenient to use the clamping device.

[0009] To achieve the above object, the inventor provides a grinding machine for processing hard and brittle bars, comprising a frame, a feeding device, a clamping device and a grinding device.

[0010] The feeding device, the clamping device and the grinding device are all arranged on the frame, the feeding device is used to feed the hard and brittle bar material, the clamping device is used to clamp the hard and brittle bar material, and the grinding device is used to grind the hard and brittle bar material;

[0011] The feeding device comprises a feeding frame, a feeding mechanism, a material receiving mechanism and an adjusting mechanism;

[0012] The feeding mechanism and the receiving mechanism are movably arranged on the feeding frame, the feeding mechanism and the receiving mechanism can slide relatively along the extension direction of the feeding frame, the adjustment mechanism is arranged relative to the feeding mechanism, and the adjustment mechanism is arranged on the frame;

[0013] The feeding mechanism comprises a feeding base, a clamping assembly and a lifting assembly arranged on the feeding base, wherein the clamping assembly is arranged on the lifting assembly, the clamping assembly is used to clamp the hard and brittle bar material, and the lifting assembly is used to drive the clamping assembly to move in the vertical direction;

[0014] The adjustment mechanism is arranged above the clamping assembly, and is used to adjust the position of the hard and brittle rod so that the center position of the hard and brittle rod in the length direction is located at a specified position of the clamping assembly.

[0015] Different from the prior art, the above technical solution uses a feeding mechanism to feed hard and brittle bars, and a receiving mechanism to receive the hard and brittle bars after processing. The feeding mechanism and the receiving mechanism can slide relatively along the extension direction of the feeding frame, which is convenient for loading and receiving hard and brittle bars; the adjustment mechanism is arranged relative to the feeding mechanism, and the adjustment mechanism is arranged above the clamping assembly. The adjustment mechanism is used to adjust the position of the hard and brittle bars so that the center position of the hard and brittle bars in the length direction is located at the designated position of the clamping assembly. In this way, after each feeding, the center position of the hard and brittle bars in the length direction can be adjusted through the adjustment mechanism, so that the center position of the hard and brittle bars in the length direction is located at the designated position of the clamping assembly, which is convenient for the subsequent clamping of the clamping device.

[0016] As an embodiment of the present invention, the adjustment mechanism includes an adjustment transmission assembly, two clamping arms and an adjustment drive unit. The adjustment drive unit is respectively connected to the two clamping arms through the adjustment transmission assembly and simultaneously drives the two clamping arms to move closer to or away from each other.

[0017] In this way, the two clamping arms are driven closer to or farther away from each other by adjusting the driving unit at the same time. When the position of the hard and brittle bar needs to be adjusted, the loading mechanism transports the hard and brittle bar between the two clamping arms, and the two clamping arms clamp inward at the same time, which can ensure that the center position of the hard and brittle bar in the length direction is located at the specified position of the adjustment mechanism each time. The driving unit is adjusted to release the two clamping arms from the hard and brittle bar, and the loading mechanism continues to load the hard and brittle bar, which is convenient for the subsequent clamping device to clamp.

[0018] As an embodiment of the present invention, the adjustment transmission assembly includes a gear and two racks, the adjustment drive unit is connected to the gear transmission, the two racks are respectively located at the upper and lower ends of the gear and are respectively meshed with the gear, and the two racks are respectively connected to two clamping arms.

[0019] In this way, through the cooperation of the gear and the two racks, the two clamping arms are respectively connected to the two racks. When the adjustment drive unit drives the gear to rotate, the two racks extend or retract from two directions respectively, and drive the two clamping arms to synchronously release or clamp the hard and brittle bars. At this time, no matter what position the hard and brittle bars are located during loading, when the adjustment mechanism adjusts the hard and brittle bars and releases them, it can ensure that the center position of the hard and brittle bars in the length direction is relative to the position of the gear, and each time it can ensure that the center position of the hard and brittle bars in the length direction is placed in the fixed position of the clamping assembly, thereby further facilitating the clamping of subsequent clamping devices.

[0020] As an embodiment of the present invention, the adjustment mechanism further comprises a truss, and the truss is provided with an adjustment slide rail, and the two clamping arms can move relatively along the extension direction of the truss through the adjustment slide rail respectively.

[0021] In this way, the two clamping arms are respectively arranged on the truss by adjusting the slide rails, so as to ensure the stability of the movement of the two clamping arms and prevent the displacement of the clamping arms in other directions.

[0022] As an embodiment of the present invention, the clamping assembly includes a clamping base plate, a limit pad and an adjustment unit. The limit pad is movably arranged on the clamping base plate, the limit pad is used to limit the displacement of the hard and brittle rod material, and the adjustment unit is transmission connected to the limit pad, and the adjustment unit is used to adjust the position of the limit pad on the clamping base plate.

[0023] In this way, the position of the limiting pad 21 can be adjusted during use through the adjustment unit, and can adapt to hard and brittle rods of various sizes, which is flexible to use.

[0024] As an embodiment of the present invention, the jacking assembly includes a fixed seat and a jacking drive unit, the clamping assembly is arranged on the fixed seat, the jacking drive unit is arranged on one side of the fixed seat, the jacking drive unit is connected to the fixed seat through a transmission assembly, and the transmission assembly is configured to convert the horizontal force output by the jacking drive unit into the vertical force, thereby driving the fixed seat to move in the vertical direction.

[0025] In this way, the upward driving method of the jacking cylinder is eliminated, and the vertical movement is changed to horizontal movement through the transmission assembly, thereby reducing the vertical length of the jacking drive unit. The jacking drive unit is arranged on one side of the fixed seat to facilitate maintenance and repair by maintenance personnel.

[0026] As an embodiment of the present invention, the clamping device includes a clamping frame, a front clamping assembly and a rear clamping rotating assembly.

[0027] The front clamping assembly and the rear clamping rotating assembly are arranged below the clamping frame, the front clamping assembly and the rear clamping rotating assembly are arranged opposite to each other, and a space for clamping the hard and brittle bar is reserved between the front clamping assembly and the rear clamping rotating assembly;

[0028] The rear clamping rotating assembly is configured to clamp the hard and brittle bar with the front clamping assembly, so that the hard and brittle bar is suspended and clamped below the clamping frame, and the hard and brittle bar can rotate around the axis.

[0029] In this way, the clamping frame is placed above the hard and brittle bar material, avoiding interference between the clamping frame and the rough grinding power head and the fine grinding power head, thereby facilitating the processing of the hard and brittle bar material by the rough grinding power head and the fine grinding power head.

[0030] As an embodiment of the present invention, a distance sensor is provided on the grinding device, and the distance sensor is arranged toward the side of the hard and brittle rod on the clamping device. The distance sensor is used to detect whether the side of the hard and brittle rod on the clamping device is parallel to the grinding surface of the grinding device. The distance sensor is arranged on the grinding device through a sliding mechanism.

[0031] In this embodiment, the grinding surface of the grinding device is perpendicular to the horizontal plane.

[0032] In this way, by means of the distance sensor arranged on the grinding device, any three points on the side of the hard and brittle bar can be detected, thereby forming a plane to determine whether the side of the hard and brittle bar is parallel to the grinding surface of the grinding device; since the grinding surface of the grinding device is perpendicular to the horizontal plane, when the side of the hard and brittle bar is parallel to the grinding surface of the grinding device, the amount of grinding at this time is the least, which is convenient for the processing of the grinding device. Secondly, since the distance sensor is arranged on the grinding device through a sliding mechanism, when the grinding device is grinding the side of the hard and brittle bar, the distance sensor can be retracted through the sliding mechanism, thereby protecting the distance sensor and preventing the grinding chips from causing the distance sensor to fail or damage the distance sensor.

[0033] As an embodiment of the present invention, the grinding device is provided with three or more distance sensors, the three or more distance sensors are arranged in a vertical direction, and the three or more distance sensors cooperate with each other to detect whether the side surface of the hard and brittle bar material is parallel to the grinding surface of the grinding device;

[0034] The grinding device also includes a controller, which is connected to and controls the rear clamping rotating assembly. The controller is used to receive signals from more than three distance sensors and control the rear clamping rotating assembly based on the signals transmitted by more than three distance sensors. The rear clamping rotating assembly is also used to rotate the hard and brittle bar.

[0035] In this way, by setting more than three distance sensors in the vertical direction, the three points form a surface, which can speed up the detection speed and obtain whether the side surface of the hard and brittle bar is parallel to the grinding surface of the grinding device. If the side surface of the hard and brittle bar is not parallel to the grinding surface of the grinding device, the controller controls the rear clamping rotating assembly to rotate the hard and brittle bar until the side surface of the hard and brittle bar is parallel to the grinding surface of the grinding device, or the side surface of the hard and brittle bar is close to being parallel to the grinding surface of the grinding device, which can effectively reduce the processing amount of the grinding device.

[0036] As an embodiment of the present invention, the grinding device includes a fixed frame, a lifting assembly, a first grinding assembly and a second grinding assembly.

[0037] The first grinding assembly and the second grinding assembly are arranged in the fixed frame, and the first grinding assembly and the second grinding assembly are arranged along a processing direction;

[0038] Wherein, the lifting assembly is used to drive the first grinding assembly and the second grinding assembly to move in the vertical direction.

[0039] In this way, the first grinding assembly and the second grinding assembly are driven to move upward and downward at the same time by the lifting assembly, which can be suitable for hard and brittle bars of different sizes and is easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0119] In order to explain the technical content, structural features, achieved objectives and effects of the technical solution in detail, the following is a detailed description in conjunction with specific embodiments and accompanying drawings.

[0120] In the description of this application, unless otherwise clearly specified and limited, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance; unless otherwise specified or explained, the term "plurality" refers to two or more; the terms "connected" and "fixed" should be understood in a broad sense, for example, "connected" can be a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0121] In the description of this specification, it should be understood that the directional words such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described at the angles shown in the accompanying drawings and should not be understood as limitations on the embodiments of the present application. In addition, in the context, it should also be understood that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.

[0122] In the prior art, the traditional processing methods for squaring, grinding and rounding of hard and brittle bars at home and abroad are three separate processes, that is, three different equipments are used to complete the whole processing of single crystal silicon bars. In actual operation, the wire squarer usually needs to use adhesive to square the hard and brittle bars at the same time, and then the squared hard and brittle bars are separately rounded by the cylindrical grinder, and finally sent to the surface grinder for surface grinding and polishing.

[0123] The inventor found that the existing feeding mechanism cannot ensure that the center position of the hard and brittle bar in the length direction is located at the specified position of the clamping assembly. When it comes to hard and brittle bars of different lengths, the subsequent clamping device cannot clamp the hard and brittle bar. One end of the hard and brittle bar may exceed the clamping range of the clamping device, while the other end is within the clamping range of the clamping device, which makes it inconvenient to use the clamping device.

[0124] In this embodiment, the direction indicated by the arrow x in the figure is the movement direction of the feeding mechanism 42, the receiving mechanism 41 or the width direction of the hard and brittle rod, and the direction indicated by the arrow y in the figure is the length direction of the hard and brittle rod, wherein the direction indicated by the arrow x and the direction indicated by the arrow y can be collectively referred to as the horizontal direction; the direction indicated by the arrow z is the vertical direction.

[0125] See also Figure 1 and Figure 2 This embodiment relates to a grinding device, including a frame 5, a feeding device 4, a clamping device 6 and a grinding device 7. The frame 5 can be implemented in the form of a base, a bracket, etc. The feeding device 4 is arranged on the frame 5, and the feeding device 4 is used to feed and unload hard and brittle bars; the clamping device 6 is arranged on the frame 5, and the clamping device 6 is used to clamp the hard and brittle bars; the hard and brittle bars are arranged on the frame 5; and the grinding device 7 is used to process the hard and brittle bars and grind the surface of the hard and brittle bars.

[0126] In this embodiment, the feeding device 4 includes a feeding mechanism 42 and a receiving mechanism 41. The feeding mechanism 42 is used to feed hard and brittle bars; the receiving mechanism 41 is used to receive hard and brittle bars after processing. The feeding mechanism 42 and the receiving mechanism 41 can slide relative to each other in the horizontal direction through the slide rails.

[0127] See also Figure 1 , Figure 2 , Figure 3 In this embodiment, the feeding device 4 includes a feeding frame 43, a feeding mechanism 42, a receiving mechanism 41 and an adjusting mechanism 44; the feeding mechanism 42 and the receiving mechanism 41 are movably arranged on the feeding frame 43, the feeding mechanism 42 and the receiving mechanism 41 can slide relative to each other along the extension direction of the feeding frame 43, and the adjusting mechanism 44 is arranged relative to the feeding mechanism; the feeding mechanism 42 includes a feeding base 1 and a clamping assembly 2 and a lifting assembly 3 arranged on the feeding base 1, the clamping assembly 2 is arranged on the lifting assembly 3, the clamping assembly 2 is used to clamp hard and brittle rods, and the lifting assembly 3 is used to drive the clamping assembly 2 to move in the vertical direction; the adjusting mechanism 44 is arranged above the clamping assembly 2, and the adjusting mechanism 44 is used to adjust the position of the hard and brittle rod so that the center position of the hard and brittle rod in the length direction is located at the specified position of the clamping assembly 2.

[0128] In actual use, the adjustment mechanism 44 is not limited to adjusting the center position of the hard and brittle rod in the length direction or the center position of the hard and brittle rod in the width direction, both of which are within the protection scope of this embodiment.

[0129] Different from the prior art, the above technical solution uses a feeding mechanism to feed hard and brittle bars, and a receiving mechanism to receive the hard and brittle bars after processing. The feeding mechanism 42 and the receiving mechanism 41 can slide relatively along the extension direction of the feeding frame 43, which is convenient for feeding and receiving hard and brittle bars. The adjustment mechanism 44 is arranged relative to the feeding mechanism, and the adjustment mechanism 44 is arranged above the clamping assembly 2. The adjustment mechanism 44 is used to adjust the position of the hard and brittle bars so that the center position of the hard and brittle bars in the length direction is located at the designated position of the clamping assembly 2. In this way, after each feeding, the center position of the hard and brittle bars in the length direction can be adjusted by the adjustment mechanism 44, so that the center position of the hard and brittle bars in the length direction is located at the designated position of the clamping assembly 2, which is convenient for the subsequent clamping device to clamp.

[0130] In some embodiments, see Figure 4 The adjustment mechanism 44 includes an adjustment transmission assembly 441, two clamping arms 442 and an adjustment drive unit 443. The adjustment drive unit 443 is respectively connected to the two clamping arms 442 through the adjustment transmission assembly 441, and simultaneously drives the two clamping arms 442 to move closer to or away from each other.

[0131] In this way, by adjusting the driving unit 443, the two clamping arms 442 are driven to move closer to or away from each other at the same time. When the position of the hard and brittle bar needs to be adjusted, the loading mechanism transports the hard and brittle bar between the two clamping arms 442. The two clamping arms 442 clamp inward at the same time, which can ensure that the center position of the hard and brittle bar in the length direction is located at the specified position of the adjustment mechanism 44 each time. The driving unit 443 is adjusted to release the two clamping arms 442 from the hard and brittle bar, and the loading mechanism continues to load the hard and brittle bar, which is convenient for the subsequent clamping device to clamp.

[0132] In this embodiment, the two clamping arms 442 clamp the hard and brittle rods respectively through the clamping pads 445 , and the clamping pads 445 play the role of buffering and protecting the hard and brittle rods.

[0133] In some embodiments, the adjustment transmission assembly 441 includes a gear 4412 and two racks 4412, the adjustment drive unit 443 is transmission-connected to the gear 4412, the two racks 4412 are respectively located at the upper and lower ends of the gear 4412, and are respectively meshed with the gear 4412, and the two racks 4412 are respectively connected to the two clamping arms 442.

[0134] In this way, through the cooperation of the gear 4412 and the two racks 4412, the two clamping arms 442 are respectively connected to the two racks 4412. When the adjustment drive unit 443 drives the gear 4412 to rotate, the two racks 4412 extend or retract from two directions respectively, and drive the two clamping arms 442 to synchronously release the hard and brittle bars or clamp the hard and brittle bars; at this time, no matter what position the hard and brittle bars are located at when loading, when the adjustment mechanism 44 adjusts the hard and brittle bars and releases them, it can ensure that the center position of the hard and brittle bars in the length direction is relative to the position of the gear 4412, and each time it can ensure that the center position of the hard and brittle bars in the length direction is placed in the fixed position of the clamping assembly 2, thereby further facilitating the clamping of the subsequent clamping device 6.

[0135] In some embodiments, the adjustment mechanism 44 further includes a truss 444 , on which an adjustment slide rail 4441 is disposed, and the two clamping arms 442 can move relative to each other along the extension direction of the truss 444 through the adjustment slide rail 4441 .

[0136] In this way, the two clamping arms 442 are respectively set on the truss 444 by adjusting the slide rails 4441, so as to ensure the stability of the movement of the two clamping arms 442 and prevent the displacement of the clamping arms 442 in other directions.

[0137] In this embodiment, the principle of the adjustment mechanism 44 is to place the hard and brittle bars on the clamping assembly through a robot or manually, the clamping assembly clamps the hard and brittle bars, and transports the hard and brittle bars to the bottom of the adjustment mechanism 44 by driving the loading mechanism to move in the extension direction of the loading frame 43; then the hard and brittle bars are lifted to the position of the two clamping arms 442 of the adjustment mechanism 44 by the lifting assembly, and the clamping assembly releases the hard and brittle bars; the adjustment drive unit 443 drives the gear 4412 to rotate, thereby driving the two clamping arms 442 to clamp the hard and brittle bars inward synchronously, ensuring that the center position of the hard and brittle bars in the length direction is relative to the gear 4412; then the adjustment drive unit 443 drives the gear 4412 to rotate, the two clamping arms 442 release the hard and brittle bars, and the hard and brittle bars are now located at the specified position of the clamping assembly, the lifting assembly lowers the hard and brittle bars, and the loading mechanism moves along the extension direction of the loading frame 43, thereby transporting them to the position of the clamping device. In this way, after each loading, the center position of the hard and brittle rod in the length direction can be adjusted through the adjustment mechanism 44, so that the center position of the hard and brittle rod in the length direction is located at the specified position of the clamping assembly, which is convenient for subsequent clamping of the clamping device.

[0138] See also Figures 2 to 6 The feeding mechanism 42 in this embodiment includes a feeding base 1 and a clamping assembly 2 and a lifting assembly 3 arranged on the feeding base 1; the clamping assembly 2 is arranged on the lifting assembly 3, the clamping assembly 2 is used to clamp hard and brittle rods, and the lifting assembly 3 is used to drive the clamping assembly 2 to move in the vertical direction; wherein, the clamping assembly 2 includes a clamping base plate 24, a limiting pad 21 and an adjusting unit, the limiting pad 21 is movably arranged on the clamping base plate 24, the limiting pad 21 is used to limit the displacement of the hard and brittle rods, the adjusting unit is transmission-connected to the limiting pad 21, and the adjusting unit is used to adjust the position of the limiting pad 21 on the clamping base plate 24.

[0139] Thus, the technical solution of the present application includes a clamping base plate 24, a limiting pad 21 and an adjusting unit, wherein the limiting pad 21 is movably arranged on the clamping base plate 24, the limiting pad 21 is used to limit the displacement of the hard and brittle bar, the adjusting unit is in transmission connection with the limiting pad 21, and the adjusting unit is used to adjust the position of the limiting pad 21 on the clamping base plate 24. At this time, the position of the limiting pad 21 can be adjusted during use, and can adapt to hard and brittle bars of various sizes, and is flexible to use.

[0140] In some embodiments, see Figure 5 and Figure 6As shown, the clamping assembly 2 includes two limit pads 21, which are movably arranged at the two ends of the clamping bottom plate 24, and the adjustment unit is used to simultaneously adjust the positions of the two limit pads 21 on the clamping bottom plate 24. In this way, the two ends of the hard and brittle bar are limited by the two limit pads 21, and the adjustment unit is used to simultaneously adjust the positions of the two limit pads 21 on the clamping bottom plate 24; in this embodiment, the distance between the two limit pads 21 can be adjusted by the adjustment unit to be suitable for hard and brittle bars of various specifications and lengths.

[0141] In some embodiments, the adjustment unit includes two wheel groups 251, a belt 252 and two pushing blocks 253. The two wheel groups 251 are respectively fixed at two ends of the clamping base plate 24. The belt 252 is wrapped around the two wheel groups 251 and is transmission-connected to the two wheel groups 251. One of the two pushing blocks 253 is arranged on the left side of a limiting pad 21, and the other pushing block 253 is arranged on the right side of the other limiting pad 21. The two pushing blocks 253 are respectively fixed on the belt 252. The belt 252 is configured so that when the belt 252 rotates around the wheel group 251, the two pushing blocks 253 respectively push the two limiting pads 21 closer to each other on the clamping base plate 24.

[0142] In this embodiment, the belt 252 rotates clockwise around the wheel set 251, and the two pushing blocks 253 respectively push the two limit pads 21 to approach each other on the clamping base plate 24. However, in other embodiments, the belt 252 can rotate counterclockwise around the wheel set 251, or the two pushing blocks 253 can respectively push the two limit pads 21 to approach each other on the clamping base plate 24, which is also within the protection scope of this embodiment.

[0143] The wheel set 251 may be a synchronous pulley, a sprocket, a V-type pulley, a flat pulley, etc., all of which are within the protection scope of this embodiment.

[0144] Thus, when the belt 252 rotates clockwise around the wheel set 251, the push block 253 on the left pushes the limit pad 21 on the left to the right, and the push block 253 on the right pushes the limit pad 21 on the right to the left, thereby reducing the distance between the two limit pads 21; at this time, it is convenient to control the distance between the two limit pads 21, and the positions of the two limit pads 21 can be adjusted simultaneously by rotating the belt 252. When the belt 252 rotates counterclockwise around the wheel set 251, the push block 253 on the left moves away from the limit pad 21 on the left, and the push block 253 on the right moves away from the limit pad 21 on the right, and the limit pad 21 needs to be reset manually.

[0145] In some embodiments, the adjustment unit further includes an adjustment handle 254, which is connected to any one of the wheel sets 251, and is used to drive the wheel set 251 to rotate, thereby driving the belt 252 to rotate. In this way, by connecting the adjustment handle 254 to any one of the wheel sets 251, when the adjustment handle 254 is rotated, the wheel set 251 can be rotated, which is convenient for the operator to use.

The clamping drive unit 23 is arranged on one side of the limiting pad 21, and the clamping block 22 is arranged on the output end of the clamping drive unit 23. The clamping drive unit 23 is used to drive the clamping block 22 to clamp the hard and brittle bars on the limiting pad 21. In this way, the hard and brittle bars to be processed can be placed on the limiting pad 21; at this time, the hard and brittle bars can be directly loaded manually or loaded by an external manipulator. The clamping drive unit 23 drives the clamping block 22 to clamp the hard and brittle bars to prevent the hard and brittle bars from moving during the loading process. In this embodiment, the hard and brittle bars are limited by the cooperation of the two limiting pads 21 and the clamping block 22 to limit the position of the hard and brittle bars during the loading process.

[0147] In some embodiments, a clamping slide rail 241 is provided on the clamping base plate 24, and the clamping slide rail 241 is provided along the extension direction of the clamping base plate 24, and the limiting pad 21 is provided on the clamping base plate 24 through the clamping slide rail 241. In this way, the position of the limiting pad 21 can be limited by the clamping slide rail 241 provided at the bottom of the clamping base plate 24, so that the limiting pad 21 can move smoothly along the extension direction of the clamping base plate 24.

[0148] In some embodiments, see Figure 6 As shown, the belt 252 includes an upper belt 2521 and a lower belt 2522, and two push blocks 253, one of which is fixed on the lower belt 2522, and the other push block 253 is fixed on the upper belt 2521. In this way, the belt 252 can be rotated well, and the two push blocks 253 can be brought close to each other for easy use.

[0149] In this embodiment, the use principle of the adjustment unit is that before use, according to the length of the hard and brittle bar, the handle 254 is adjusted to drive the belt 252 to rotate, thereby adjusting the distance between the two limit pads 21, and then the hard and brittle bar is placed on the two limit pads 21; the clamping drive unit 23 drives the clamping block 22 to clamp the hard and brittle bar. In other embodiments, a single limit pad 21 can also be used to clamp the hard and brittle bar. In this way, the position of the limit pad 21 can be adjusted during use, and it can adapt to hard and brittle bars of various sizes, and it is flexible to use.

[0150] In some embodiments, see Figure 7 As shown, the jacking assembly 3 includes a fixed seat 31 and a jacking drive unit 32, the clamping assembly 2 is arranged on the fixed seat 31, the jacking drive unit 32 is arranged on one side of the fixed seat 31, and the jacking drive unit 32 is connected to the fixed seat 31 through a transmission assembly. The transmission assembly is configured to convert the horizontal force output by the jacking drive unit 32 into a vertical force, thereby driving the fixed seat 31 to move in the vertical direction.

[0151] In this embodiment, the lifting drive unit 32 is arranged on one side of the fixing seat 31, and the lifting drive unit 32 is connected to the fixing seat 31 through a transmission assembly. The transmission assembly is configured to convert the horizontal force output by the lifting drive unit 32 into a vertical force, thereby driving the vertical movement of the fixing seat 31. In this way, the upward driving method of the lifting cylinder is cancelled, and the vertical movement is changed to the horizontal movement through the transmission assembly, which reduces the length of the lifting drive unit 32 in the vertical direction. The lifting drive unit 32 is arranged on one side of the fixing seat 31, which is convenient for maintenance personnel to maintain and repair.

[0152] In some embodiments, the transmission assembly is an oblique linear transmission assembly, and the transmission assembly includes a first slide rail 331 and a first slider 332. The first slide rail 331 is obliquely arranged on the fixed seat 31, and the first slider 332 cooperates with the first slide rail 331, and the first slider 332 can slide relatively along the extension direction of the first slide rail 331; wherein, the output end of the jacking drive unit 32 is connected to the first slider 332, and the jacking drive unit 32 is used to drive the first slider 332 to move relatively along the extension direction of the first slide rail 331.

[0153] In this way, by using the transmission component as an oblique linear transmission component, when the jacking drive unit 32 drives the first slider 332 to slide along the inclined first slide rail 331, the fixed seat 31 can be driven to move upward, thereby realizing the conversion of vertical movement into horizontal movement. Its structure is simple and easy to operate.

[0154] In some embodiments, the transmission assembly further includes a second slide rail 333 and a second slider 334, and the lifting assembly 3 further includes a base plate 34, the second slide rail 333 is arranged on the base plate 34, the second slide rail 333 extends in the horizontal direction, the second slider 334 cooperates with the second slide rail 333, and the second slider 334 can slide relatively along the extension direction of the second slide rail 333; wherein the first slider 332 is connected to the second slider 334, so that when the first slider 332 slides relatively along the first slide rail 331, the second slider 334 slides relatively along the second slide rail 333. In this embodiment, the lifting drive unit 32 is arranged on the base plate 34, and the output end of the lifting drive unit 32 is connected to the second slider 334. In this way, by setting the second slide rail 333 on the base plate 34, the lifting drive unit 32 can drive the first slider 332 to slide on the first slide rail 331 as long as it drives the second slider 334 to slide on the second slide rail 333, and the structure is stable and convenient for processing.

[0155] In some embodiments, a set of first slide rails 331, first slider 332, second slide rails 333 and second slider 334 are disposed on both sides of the fixed seat 31, and the first slide rails 331, first slider 332, second slide rails 333 and second slider 334 on both sides of the fixed seat 31 are symmetrically disposed. In this way, by disposing two sets of first slide rails 331, first slider 332, second slide rails 333 and second slider 334 on both sides of the fixed seat 31, the transmission assembly is more stable, and the forces on both sides of the fixed seat 31 are stable, avoiding the problem of unilateral force and easy damage to parts.

[0156] In some embodiments, the transmission assembly further includes a connection block 35, which is respectively connected to the second sliders 334 on both sides of the fixing seat 31, and the output end of the lifting drive unit 32 is connected to the connection block 35. In this way, as long as the connection block 35 is driven to move, the two second sliders 334 can be driven to move simultaneously, thereby ensuring the synchronization of the second sliders 334 on both sides of the fixing seat 31.

[0157] In some embodiments, the transmission assembly further includes a screw rod 36 arranged in the horizontal direction, a threaded hole matching the screw rod 36 is arranged on the connection block 35, and the lifting drive unit 32 is a drive motor, which is used to drive the screw rod 36 to rotate, thereby driving the connection block 35 to move in the horizontal direction. In this embodiment, the lifting drive unit 32 is a drive motor, which can accurately control the rotation of the screw rod 36, thereby realizing accurate driving of the connection block 35 to move in the horizontal direction.

[0158] In some embodiments, the feeding mechanism 42 further includes a linear sliding assembly 37, and the lifting assembly 3 further includes a base plate 34. The linear sliding assembly 37 is disposed on the base plate 34, and the linear sliding assembly 37 is connected to the clamping assembly 2. In this embodiment, the feeding mechanism 42 includes four linear sliding assemblies 37, and the four linear sliding assemblies 37 are respectively disposed at the four corners of the base plate 34; the function of the linear sliding assembly 37 is to ensure the stability of the clamping assembly 2 when the lifting assembly 3 lifts the clamping assembly 2, and can effectively prevent the clamping assembly 2 from tilting.

[0159] In this embodiment, the principle of the loading mechanism 42 is: the hard and brittle rods to be processed are placed on the limiting pad 21, the clamping drive unit 23 drives the clamping block 22 to clamp the hard and brittle rods, and the lifting drive unit 32 drives the screw rod 36 to rotate, so that the connecting block 35 moves in the horizontal direction, thereby driving the first slider 332 and the second slider 334 to move along the first slide rail 331 and the second slide rail 333 respectively, and finally driving the fixed seat 31 to rise or fall, and driving the clamping assembly 2 to rise or fall.

[0160] See also Figures 8 to 12 A distance sensor 75 is provided on the grinding device 7. The distance sensor 75 is arranged toward the side of the hard and brittle rod 8 on the clamping device. The distance sensor 75 is used to detect whether the side of the hard and brittle rod 8 on the clamping device 6 is parallel to the grinding surface of the grinding device. The distance sensor 75 is arranged on the grinding device 7 through a sliding mechanism 76.

[0161] In this embodiment, it is mainly possible to ensure that the surface to be ground is parallel to the plane of the grinding head, or perpendicular to the axis of the grinding head. In this embodiment, the grinding surface of the grinding device is perpendicular to the horizontal plane, and the hard and brittle bar 8 is preferably perpendicular to the horizontal plane, or nearly perpendicular to the horizontal plane.

[0162] In this embodiment, the distance sensor 75 provided on the grinding device can detect any three points on the side of the hard and brittle bar 8, thereby forming a plane to obtain whether the side of the hard and brittle bar 8 is parallel to the grinding surface of the grinding device; since the grinding surface of the grinding device 7 is perpendicular to the horizontal plane, when the side of the hard and brittle bar 8 is parallel to the grinding surface of the grinding device, the grinding amount at this time is the least, which is convenient for the processing of the grinding device 7. Secondly, since the distance sensor 75 is provided on the grinding device 7 through the sliding mechanism 76, when the grinding device 7 performs grinding processing on the side of the hard and brittle bar 8, the distance sensor 75 can be retracted through the sliding mechanism 76, which protects the distance sensor 75 and prevents the grinding chips from causing the distance sensor 75 to fail or damage the distance sensor 75.

[0163] In some embodiments, more than three distance sensors 75 are disposed on the grinding device, and the more than three distance sensors 75 are disposed in the vertical direction. The more than three distance sensors 75 cooperate with each other to detect whether the side surface of the hard and brittle rod is parallel to the grinding surface of the grinding device.

[0164] In this way, by setting more than three distance sensors 75 in the vertical direction, three points form a surface, which can speed up the detection speed. After the detection, through calculation, it can be obtained whether the side surface of the hard and brittle rod is parallel to the grinding surface of the grinding device, thereby improving efficiency.

[0165] In some embodiments, the sliding mechanism 76 includes a sliding slider 761 and a sliding drive unit 762. A sliding rail 763 is provided on the grinding device. Three or more distance sensors 75 are provided on the sliding slider 761. The sliding slider 761 is provided on the sliding rail 763 and can slide relatively along the extension direction of the sliding rail 763. The sliding drive unit 762 is used to drive the sliding slider 761 to slide relatively along the extension direction of the sliding rail 763.

[0166] In this way, more than three distance sensors 75 are arranged on the sliding slider 761, and the sliding drive unit 762 is used to drive the sliding slider 761 to slide relatively along the extension direction of the sliding rail 763; when measurement is required, more than three distance sensors 75 are extended, and before the grinding device performs grinding processing, more than three distance sensors 75 are retracted to protect the more than three distance sensors 75 to avoid or at least reduce the failure or damage of the distance sensors 75.

[0167] In some embodiments, see Fig.12 The grinding device also includes a controller 77, which is connected to and controls the rear clamping rotating assembly 63. The controller 77 is used to receive signals from more than three distance sensors 75, and control the rear clamping rotating assembly 63 according to the signals transmitted by more than three distance sensors 75. The rear clamping rotating assembly 63 is also used to rotate the hard and brittle rod 8.

[0168] In this way, the side position information of the hard and brittle rod is detected by more than three distance sensors 75 to obtain whether the side of the hard and brittle rod 8 is parallel to the grinding surface of the grinding device. If the side of the hard and brittle rod 8 is not parallel to the grinding surface of the grinding device, the controller 77 controls the rear clamping rotating assembly 63 to rotate the hard and brittle rod 8 until the side of the hard and brittle rod 8 is parallel to the grinding surface of the grinding device, or the side of the hard and brittle rod 8 is close to perpendicular to the horizontal plane, which can effectively reduce the processing amount of the grinding device 7.

[0169] In some embodiments, the sliding mechanism 76 also includes a position sensor 764, which is used to detect the position of the sliding slider 761 and send the position signal of the sliding slider 761 to the controller 77. The controller 77 is connected to and controls the sliding drive unit 762. The controller 77 is also used to receive the position signal transmitted by the position sensor 764 and control the sliding drive unit 762 according to the position signal transmitted by the position sensor 764.

[0170] In this way, the position of the sliding slider 761 can be detected by the position sensor 764 , and after the detection, the sliding drive unit 762 is controlled by the controller 77 to achieve precise control of the position of the sliding slider 761 .

[0171] In this embodiment, the principle of the distance sensor 75 is: during use, the loading device 4 loads the hard and brittle rod 8, and the clamping device 6 clamps the hard and brittle rod 8; before the grinding device 7 processes the hard and brittle rod 8, the distance sensor 75 extends through the sliding mechanism 76 to detect any three points on the side of the hard and brittle rod 8 to determine whether the side of the hard and brittle rod 8 is parallel to the grinding surface of the grinding device; if the side of the hard and brittle rod 75 is not perpendicular to the horizontal plane, the controller 77 controls the rear clamping rotating assembly to rotate the hard and brittle rod until the side of the hard and brittle rod is parallel to the grinding surface of the grinding device, or the side of the hard and brittle rod is close to being perpendicular to the horizontal plane. The distance sensor 75 is retracted through the sliding mechanism 76, and the grinding device 7 processes the hard and brittle rod 8. After the processing is completed, the hard and brittle rod is rotated by the clamping rotating component to process the other two surfaces of the hard and brittle rod 8. The distance sensor 75 is also required when processing two surfaces to detect any three points on the side of the hard and brittle rod 8. The above steps are repeated to finally complete the processing of the four surfaces of the hard and brittle rod 8.

[0172] Please continue reading Figures 8 to 11 The present embodiment relates to a grinding device 7 for processing hard and brittle rods, including a fixed frame 71, a lifting assembly 72, a first grinding assembly 73 and a second grinding assembly 74, wherein the first grinding assembly 73 and the second grinding assembly 74 are arranged in the fixed frame 71, and the first grinding assembly 73 and the second grinding assembly 74 are arranged along the processing direction, wherein the lifting assembly 72 is used to drive the first grinding assembly 73 and the second grinding assembly 74 to move in the vertical direction (as indicated by the z arrow in the figure).

[0173] In this embodiment, the first grinding assembly 73 and the second grinding assembly 74 are arranged along the processing direction, and the lifting assembly 72 is used to drive the first grinding assembly 73 and the second grinding assembly 74 to move in the vertical direction (the direction indicated by the z arrow in the figure). In this way, the lifting assembly 72 drives the first grinding assembly 73 and the second grinding assembly 74 to move upward and downward at the same time, which can be used for hard and brittle bars of different sizes and is easy to use.

[0174] In some embodiments, the processing accuracy of the first grinding assembly 73 is less than that of the second grinding assembly 74; in this way, the first grinding assembly 73 is for rough grinding, and the second grinding assembly 74 is for fine grinding, and fine grinding is performed after rough grinding to facilitate the processing of hard and brittle rods.

[0175] In some embodiments, Figure 8 and 9 As shown, the lifting assembly 72 includes a lifting drive unit 721 and a lifting platform 722. The first grinding assembly 73 and the second grinding assembly 74 are both arranged on the lifting platform 722. The lifting drive unit 721 is arranged on the fixed frame 71. The output end of the lifting drive unit 721 is connected to the lifting platform 722 in a transmission manner and is used to drive the lifting platform 722 to move relative to each other in a vertical direction (in the direction indicated by the arrow z in the figure). In this way, the lifting drive unit 721 can drive the lifting platform 722 to move up and down in a vertical direction (in the direction indicated by the arrow z in the figure), thereby driving the first grinding assembly 73 and the second grinding assembly 74 to move up and down, and realizing the stable lifting and lowering of the lifting assembly 72.

In this way, the lifting platform 722 can be stably provided on the lifting rail 7221 through the lifting slider 7222, and the lifting rail 7221 is used to limit the movement of the lifting platform 722 in other directions.

[0179] In some embodiments, a lifting rail 7221 is provided at both ends of the fixing frame 71. Thus, by providing a lifting rail 7221 at both ends of the fixing frame 71, the lifting platform 722 cooperates with the two lifting rails 7221 through the lifting sliders 7222 at both ends, thereby improving the stability of the lifting platform 722 moving up and down.

[0180] In some embodiments, the first grinding assembly 73 includes a first cutter disc 731, a grinding drive unit and a translation drive unit. The grinding drive unit is used to drive the first cutter disc 731 to rotate so as to grind the hard and brittle rod. A translation guide rail 734 is provided on the lifting platform 722. The grinding drive unit and the first cutter disc 731 are arranged on the translation guide rail 734 through a translation slider 735. The translation drive unit is used to drive the first cutter disc 731 to approach or move away from the hard and brittle rod in a horizontal direction.

[0181] In this way, the first cutter disc 731 is driven to rotate by the grinding drive unit, so as to grind the hard and brittle bar stock. Here, the first cutter disc 731 is for rough grinding. The grinding drive unit and the first cutter disc 731 are arranged on the translation guide rail 734 through the translation slider 735. The translation drive unit can drive the first cutter disc 731 and the grinding drive unit to advance or retract along the direction indicated by the arrow x in the figure, so as to realize the processing of hard and brittle bar stock.

[0182] In some embodiments, the second grinding assembly 74 includes a second cutter disc 741, a grinding drive unit and a translation drive unit. The grinding drive unit is used to drive the second cutter disc 741 to rotate so as to grind the hard and brittle rod. A translation guide rail 734 is provided on the lifting platform 722. The grinding drive unit and the second cutter disc 741 are arranged on the translation guide rail 734 through a translation slider 735. The translation drive unit is used to drive the second cutter disc 741 to approach or move away from the hard and brittle rod in the horizontal direction.

[0183] In this embodiment, the first cutter disc 731 and the second cutter disc 741 are respectively disposed on the lifting platform 722 through bearing seats.

[0184] In this way, the second cutter disc 741 is driven to rotate by the grinding drive unit, so as to grind the hard and brittle bar stock.

In this way, the clamping frame 61 is above the hard and brittle bar 8, avoiding interference between the clamping frame 61 and the rough grinding power head and the fine grinding power head, and facilitating the processing of the hard and brittle bar 8 by the rough grinding power head and the fine grinding power head.

[0192] In some embodiments, see Fig.13 , two parallel slide rails 652 are arranged on the upper frame 65, and the two sides of the clamping frame 61 are respectively arranged on the slide rails 652 through sliders. In this way, the two sides of the clamping frame 61 are respectively arranged on the slide rails 652 through two sliders, and can be relatively moved smoothly along the extension direction of the slide rails 652 on the clamping frame 61.

[0193] In some embodiments, see Fig.14 The clamping frame 61 is provided with more than two weight-reducing holes 611. Thus, the weight of the clamping frame 61 can be reduced through the weight-reducing holes 611.

[0194] In some embodiments, see Fig.15 , the front clamping assembly 62 contacts one end of the hard and brittle bar 8 through the rotating member 64, and the rear clamping rotating assembly 63 contacts the other end of the hard and brittle bar 8 through the rotating member 64. The rear clamping rotating assembly 63 is used to drive the hard and brittle bar 8 to rotate around the axial direction. In this way, when processing the hard and brittle bar 8, two grinding devices 7 are used to process the two sides of the hard and brittle bar 8 respectively. After processing the two sides of the hard and brittle bar 8, the hard and brittle bar 8 can be rotated 90° through the cooperation of the rear clamping rotating assembly 63 and the rotating member 64, so that the other two sides of the hard and brittle bar 8 can be processed. At this time, a total of four sides of the hard and brittle bar 8 can be processed.

[0195] In some embodiments, the front clamping assembly 62 and / or the rear clamping rotating assembly 63 can slide forward and backward along the bottom of the clamping frame 61. In this way, the hard and brittle bar 8 can be clamped by sliding the front clamping assembly 62 and / or the rear clamping rotating assembly 63 forward and backward at the bottom of the clamping frame 61.

[0196] In some embodiments, the rear clamping rotating assembly 63 includes a clamping end 631 and a clamping driving unit, and the clamping driving unit is used to drive the clamping end 631 to approach or move away from the front clamping assembly 62 to clamp the hard and brittle bar 8. In this way, in this embodiment, the front clamping assembly 62 and the rear clamping rotating assembly 63 are fixed to the bottom of the clamping frame 61 and are immovable. The clamping driving unit can drive the clamping end 631 to extend and retract, thereby clamping the hard and brittle bar 8.

[0197] In this embodiment, the principle of the clamping device 6 is: during use, the hard and brittle rod 8 is transported to the bottom of the clamping device 6 by the loading device 4, and the clamping device 6 clamps the hard and brittle rod 8 through the rear clamping rotating assembly 63. After the clamping is completed; the sliding drive unit 762 drives the clamping frame 61 to move on the upper frame 65, and the grinding device 7 processes the two surfaces of the hard and brittle rod 8; after the processing is completed, the sliding drive unit 762 drives the clamping frame 61 to retreat, and the rear clamping rotating assembly 63 drives the hard and brittle rod 8 to rotate 90° around the axis, and the clamping frame 61 continues to move forward, and the grinding device 7 processes the other two surfaces of the hard and brittle rod 8. After the processing is completed, the clamping device 6 places the hard and brittle rod 8 on the receiving mechanism of the loading device 4.
