Description

Technical Field

[0001] This utility model relates to the field of grinding machine technology, and in particular to a power transmission and arrangement mechanism for a fully automatic four-axis thickness measuring grinding machine. Background Technology

[0002] A grinding machine is a mechanical device used for grinding the surface of workpieces. Its main function is to perform high-precision processing on workpieces using abrasive-coated or embedded grinding tools. Grinding machines are widely used for single-sided grinding and polishing of various materials, including sapphire substrates, optical glass wafers, quartz wafers, and silicon wafers. The working principle of a grinding machine is to place the workpiece on a flat grinding disc. As the grinding disc rotates, a correction wheel drives the workpiece to rotate, and pressure is applied to the workpiece by gravity or other means, causing relative friction between the workpiece and the grinding disc, thereby achieving the purpose of grinding and polishing. Because the dimensions of the workpieces vary along the width of the conveyor belt, problems can easily occur during the feeding process. For example, during the initial conveying process, workpieces may collide and become misaligned, leading to incorrect workpiece positioning. In severe cases, this can even damage the machine tool, affecting work efficiency and quality. Utility Model Content

[0027] The present invention will now be described in detail with reference to the accompanying drawings.

[0028] like Figs. 1 to 3 As shown, the power conveying arrangement mechanism of a fully automatic four-axis thickness measuring grinding machine of this utility model includes a frame 1, a frame body 2 disposed on the frame 1, a feeding guide assembly 3 disposed on the frame body 2, a feeding assembly 4 used in conjunction with the feeding guide assembly 3, and a servo motor 5 driven and connected to the feeding assembly 4. The feeding assembly 4 includes a feeding roller 41 and a driven sprocket 42 disposed on the feeding roller 41. Multiple feeding rollers 41 and multiple driven sprockets 42 are provided. The multiple driven sprockets 42 are arranged at intervals along the length direction of the frame body 2. A linkage sprocket 43 is provided on the outer side of the frame body 2. A linkage chain 44 is connected between the linkage sprocket 43 and the driven sprocket 42 and between two adjacent driven sprockets 42. The output end of the servo motor 5 is driven and connected to a drive sprocket 45. A transmission chain 46 is connected between the drive sprocket 45 and the driven sprocket 42.

[0029] During operation, the servo motor 5 intelligently adjusts its drive parameters according to actual work requirements under the control of the control system, causing the servo motor 5 to drive the drive sprocket 45 to rotate. The rotating drive sprocket 45 is connected to the driven sprocket 42 via a transmission chain 46. Multiple driven sprockets 42 are provided. Since multiple feeding rollers 41 are arranged at intervals along the length of the frame 2, each feeding roller 41 is connected to a multiple driven sprocket 42. Furthermore, a linkage chain 44 is connected between adjacent driven sprockets 42. A linkage sprocket 43 is provided on the outer side of the frame 2, and the linkage sprocket 43 is also connected to the driven sprockets 42 via a transmission chain 44. The linkage chain 44, through the setting of the linkage sprocket 43, enhances the linkage flexibility between multiple driven sprockets 42, improves the transmission efficiency between two adjacent driven sprockets 42, and thus causes multiple feeding rollers 41 to smoothly roll and transport the workpiece. Furthermore, the feeding guide assembly 3 is positioned above the multiple feeding rollers 41. By rolling and pressing against the upper surface of the workpiece, the feeding guide assembly 3 applies a certain force, thereby utilizing the supporting effect of the multiple feeding rollers 41 on the lower surface of the workpiece and the pressing effect of the feeding guide assembly 3 on the upper surface of the workpiece to better fix the position of the workpiece during the transport process and prevent the workpiece from becoming misaligned. This utility model, through the cooperative use of the feeding guide assembly 3 and the feeding assembly 4, can support and press against the workpiece from both above and below, effectively preventing workpiece misalignment and improving work efficiency and quality.

[0030] The feed guide assembly 3 in this embodiment includes a frame 31, a sleeve 32 disposed on the frame 31, a connecting rod 33 slidably connected to the sleeve 32, a guide wheel 34 disposed on the connecting rod 33, and a thickness sensor 35 disposed on the frame 31. The guide wheel 34 is slidably connected to the sleeve 32 through the connecting rod 33, so that the guide wheel 34 abuts against the thickness sensor 35. Specifically, when the guide wheel 34 rolls against the upper surface of the workpiece, the guide wheel 34 is slidably connected to the sleeve 32 through the connecting rod 33, thereby causing the guide wheel 34 to abut against the thickness sensor 35. Since the thickness sensor 35 is a mechanical thickness gauge, it typically includes a retractable measuring probe. The thickness of the workpiece is calculated by measuring the mechanical displacement generated by the probe when it contacts the guide wheel 34. Therefore, it has the characteristics of fast response, high sensitivity, and high measurement accuracy, and can respond to the input signal in a very short time and accurately record the change in thickness value.

[0031] In this embodiment, the frame 31 is provided with a mounting base 36. Both sides of the mounting base 36 are provided with mounting grooves 37 and mounting screws 38 disposed in the mounting grooves 37. A connecting hole 39 is provided on the outer side of the frame 31, and a through groove 310 is formed at the bottom of the frame 31. The mounting screws 38 pass through the mounting grooves 37 and connect to the connecting hole 39. The thickness sensor 35 is mounted on the mounting base 36, so that the measuring end of the thickness sensor 35 passes through the through groove 310 and protrudes outside the frame 31. Specifically, the mounting screws 38 pass through the mounting grooves 37 and are fixed to the connecting hole 39, thereby achieving a connection and fixation between the mounting base 36 and the frame 31. The thickness sensor 35 is mounted on the mounting base 36, and the measuring end of the thickness sensor 35 passes through the through groove 310 and protrudes outside the frame 31, so that the measuring end of the thickness sensor 35 abuts against the guide wheel 34, resulting in good structural stability.

[0032] This embodiment also includes a U-shaped frame 311, the guide wheel 34 is rotatably connected to the U-shaped frame 311, one end of the connecting rod 33 is connected to the U-shaped frame 311, a spring 312 is provided between the sleeve 32 and the U-shaped frame 311, the spring 312 is sleeved on the outside of the connecting rod 33, and a limit block 313 is provided at the other end of the connecting rod 33, the limit block 313 stops contact with the top end of the sleeve 32. Specifically, the guide wheel 34 is rotatably connected to the U-shaped frame 311. Both ends of the U-shaped frame 311 are provided with connecting rods 33, and the sleeve 32 is connected and fixed to the frame 31. The connecting rods 33 and the sleeve 32 are slidably connected. The spring 312 is sleeved on the outside of the connecting rods 33. The spring 312 is located between the sleeve 32 and the U-shaped frame 311, which helps the U-shaped frame 311 to quickly reset. When the limiting block 313 stops and abuts the top of the sleeve 32, it limits the up and down movement of the connecting rod 33 along the sleeve 32, thus providing a good limiting effect.

[0033] In this embodiment, a sensing block 314 is provided on the top of the U-shaped frame 311, and the sensing block 314 is disposed opposite to the thickness sensor 35. Specifically, the opposite disposal of the sensing block 314 and the thickness sensor 35 facilitates the accurate contact of the measuring end of the thickness sensor 35 with the sensing block 314, thereby improving the accuracy of thickness measurement.

[0034] In this embodiment, the bottom of the frame 1 is provided with a support assembly 6. The support assembly 6 includes a threaded sleeve 61, a screw 62 threadedly connected to the threaded sleeve 61, a fastening nut 63 screwed onto the outside of the screw 62, and a support leg 64 provided on the screw 62. Specifically, the screw 62 is threadedly connected to the threaded sleeve 61, and the screw 62 is connected to the support leg 64, allowing the support leg 64 to be adjusted in height relative to the threaded sleeve 61. The fastening nut 63 is screwed onto the outside of the screw 62, thereby fixing the position of the support leg 64 after the height adjustment, making the operation simple and efficient.

For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
