[0022] Reference Figure 1 This invention discloses a fully automatic double-sided grinding device, comprising a worktable 100, a feeding mechanism 200, a grinding mechanism 300, and a discharging mechanism 400. The worktable 100 is equipped with a first feeding station 101, a first storage and processing station 102, a first grinding station 103, a first discharge station 104, a second feeding station 105, a second storage and processing station 106, a second grinding station 107, and a second discharge station 108. There are two feeding mechanisms 200, with the first feeding station 101 corresponding to one of the feeding mechanisms 200, and the second feeding station 105 corresponding to the other feeding mechanism 200. There are also two grinding mechanisms 300, with the first grinding station 103 corresponding to one of the grinding mechanisms 300, and the second grinding station 107 corresponding to the other grinding mechanism 300. There are two feeding mechanisms 400. The position of the first discharge station 104 corresponds to one of the feeding mechanisms 400, and the position of the second discharge station 108 corresponds to the other grinding mechanism 300. The first material storage and processing station 102 is located between the first feeding station 101 and the first discharge station 104, and the second material storage and processing station 106 is located between the second feeding station 105 and the second grinding station 107.

[0023] The workflow of the fully automatic double-sided grinding equipment of this invention is as follows: A cutting tool 500 from one of the feeding mechanisms 200 is fed to the first feeding station 101, then transferred to the first storage and processing station 102 to wait, and then transferred to the first grinding station 103 where it is processed by one of the grinding mechanisms 300. After processing, the cutting tool 500 is transferred to the first unloading station 104, and finally transferred to one of the unloading mechanisms 400 for storage. Similarly, a cutting tool 500 from the other feeding mechanism 200 is fed to the second feeding station 105, then transferred to the second storage and processing station 106 to wait, then transferred to the second grinding station 107 where it is processed by another grinding mechanism 300. After processing, the cutting tool 500 is transferred to the second unloading station 108, and finally transferred to another unloading mechanism 400 for storage.

[0024] As can be seen, the fully automatic double-sided grinding equipment of this invention is equipped with two sets of feeding mechanisms 200, grinding mechanisms 300 and unloading mechanisms 400, and can process two sets of cutting tools 500 at the same time. It adopts a dual-station design to improve production efficiency and solve the problem of low production.

[0025] It is understood that in some other embodiments, only one set of feeding mechanism 200, grinding mechanism 300 and unloading mechanism 400 may be provided, or more than three sets may be provided.

[0026] Reference Figure 2 and Figure 3 The worktable 100 includes a base (not shown), a first drive mechanism (not shown), and a turntable 109. The turntable 109 is rotatably connected to the base. The first drive mechanism drives the turntable 109 to rotate. The turntable 109 is provided with a clamping mechanism 600 for clamping tools 500. The clamping mechanism 600 can clamp various types of tools 500. The turntable 109 is polygonal and is mounted on the base. In some embodiments, the first drive mechanism is a stepper motor. The stepper motor drives a small pulley to rotate. The turntable 109 is connected to a large pulley. A synchronous belt connects the large pulley and the small pulley, so that the turntable can be continuously fed by the stepper motor. As the turntable 109 rotates, the same clamping mechanism 600 sequentially reaches the first feeding station 101, the first storage and processing station 102, the first grinding station 103, the first unloading station 104, the second feeding station 105, the second storage and processing station 106, the second grinding station 107, and the second unloading station 108. The turntable 109 is equipped with eight clamping mechanisms 600, ensuring that each station has at least one clamping mechanism 600 when the turntable 109 rotates. This allows the loading mechanism 200, the grinding mechanism 300, and the unloading mechanism 400 to operate simultaneously, improving work efficiency.

[0027] Reference Figure 4 and Figure 5 The feeding mechanism 200 includes a feeding storage bin 201 and a feeding assembly. The feeding assembly is used to transfer the cutting tool 500 from the feeding storage bin 201 to the clamping mechanism 600. The feeding assembly includes a first conveying mechanism 202, a first flipping mechanism 203, a first feeding mechanism 204, a conveyor belt 205, and a second conveying mechanism 206.

[0028] Understandably, the feeding storage bin 201 contains multiple horizontally placed cutting tools 500. The side wall of the feeding storage bin 201 has a through groove, and a lifting box 207 is connected to it. A servo motor is installed on the lifting box 207, and a lead screw is installed inside the lifting box 207. The lead screw connects to a lifting plate, which passes through the through groove and enters the feeding storage bin 201. All the cutting tools 500 are placed on the lifting plate. The servo motor drives the lead screw to rotate, thereby causing the lifting plate to move up and down along the through groove. When one cutting tool 500 is removed from the feeding storage bin 201, the servo motor activates, causing the lifting plate to lift all the cutting tools 500, facilitating their retrieval.

[0029] The first conveying mechanism 202 can be configured as a first conveying cylinder, and the second conveying mechanism 206 can be configured as a second conveying cylinder. The first and second conveying cylinders are located at opposite ends of the conveyor belt 205. The first conveying cylinder can grab the cutting tool 500 from the feeding storage bin 201 and transport it onto the conveyor belt 205. The conveyor belt 205 then transports the tool to the second conveying cylinder, which grabs the cutting tool 500 from the conveyor belt 205 and places it in the first flipping mechanism 203. In some embodiments, both the first and second conveying cylinders use electromagnets to attract or release the cutting tool 500.

[0030] Reference Figure 6 and Figure 7 The first flipping mechanism 203 includes a flipping plate 208 and a second driving mechanism. The second driving mechanism is used to drive the flipping plate 208 to flip. The flipping plate 208 includes a flat plate portion 209 and a bent portion 210. The bent portion 210 is connected to one side of the flat plate portion 209 and extends toward the other side of the flat plate portion 209. A first limiting groove 211 is formed between the bent portion 210 and the flat plate portion 209. (Refer to...) Figure 4 The opening of the first limiting groove 211 faces the conveyor belt 205. The second handling cylinder horizontally places the tool 500 onto the tilting plate 208, and part of the tool 500 enters the first limiting groove 211. (Refer to...) Figure 5 The second drive mechanism drives the rotation by 90°, and the rotating plate 208 drives the tool 500 to rotate, so that the tool 500 is placed vertically.

[0031] Reference Figure 6The second drive mechanism includes a tilting cylinder 212, a gear 213 and a rack 214. The gear 213 and the rack 214 mesh, and the rack 214 is connected to the push rod of the tilting cylinder 212. The gear 213 is connected to the tilting plate 208. By extending and retracting the push rod of the tilting cylinder 212, the gear 213 rotates, thereby driving the tilting plate 208 to tilt, so that the tool 500 changes its posture.

[0032] Reference Figures 4 to 6 The first feeding mechanism 204 includes a transverse feeding guide module 215 and a longitudinal feeding guide module 216, which are connected. A feeding mechanical clamp 217 is mounted on the longitudinal feeding guide module 216, capable of clamping the tool 500. The longitudinal feeding guide module 216 drives the feeding mechanical clamp 217 upward to avoid the first flipping mechanism 203. The longitudinal feeding guide module 216 also drives the feeding mechanical clamp 217 downward to clamp the tool 500. The transverse feeding guide module 215 can move the feeding mechanical clamp 217 towards the clamping mechanism 600, causing the tool 500 to be clamped by the clamping mechanism 600.

[0033] Reference Figures 8 to 10 The clamping mechanism 600 includes a fixed base 601, a movable base 602, and a third drive mechanism 603. The third drive mechanism 603 drives the movable base 602 to move closer to or away from the fixed base 601 to clamp or release the tool 500. When the third drive mechanism 603 drives the movable base 602 away from the fixed base 601, the gap between the fixed base 601 and the movable base 602 increases, allowing the tool 500 to be placed between them. When the third drive mechanism 603 drives the movable base 602 closer to the fixed base 601, the gap between the fixed base 601 and the movable base 602 decreases, clamping the tool 500.

[0034] Reference Figure 11The top of the fixed base 601 is provided with a second limiting groove 604, which is used to accommodate part of the cutting tool 500. The bottom wall of the second limiting groove 604 supports the cutting tool 500 and positions the cutting tool 500 in the height direction. The width of the second limiting groove 604 is adapted to the thickness of the back of the cutting tool 500. The side wall of the second limiting groove 604 near the movable base 602 is lower, which can play a coarse positioning role and prevent the cutting tool 500 from tilting towards the movable base 602 (a small angle of tilt is allowed, but it will not fall over). The side wall of the second limiting groove 604 away from the movable base 602 is higher, which can play a limiting role and ensure that the cutting tool 500 remains vertical when it is pressed against the side wall of that side. When the first feeding mechanism 204 transfers the tool 500 to the clamping mechanism 600, the back of the tool is placed facing the second limiting groove 604. After the back of the tool is placed in the second limiting groove 604, the tool 500 can be restricted within the second limiting groove 604 and maintain a basically vertical state, thereby completing the pre-fixation of the tool 500, which facilitates the subsequent cooperation between the movable seat 602 and the fixed seat 601 to clamp the tool 500.

[0035] Reference Figures 8 to 10 and Figure 12 The movable seat 602 is provided with a pressure block 605 on its top, which is used to restrict the upward movement of the tool holder of the tool 500. When the third drive mechanism 603 drives the movable seat 602 to approach the fixed seat 601 and clamp the tool 500, the bottom surface of the pressure block 605 abuts against the top surface of the tool holder, thereby completing the upper position limit of the tool 500 and preventing the tool 500 from flipping along the vertical plane when grinding the tool 500.

[0036] Refer to 10 to Figure 12 The cutting tool 500 is provided with a limiting hole 501, and the movable seat 602 is provided with a limiting shaft (not shown in the figure), which passes through the limiting hole 501. Through the cooperation between the limiting shaft and the limiting hole 501, the movement of the cutting tool 500 along the length direction of the second limiting groove 604 can be restricted, thereby ensuring that the cutting tool 500 will not affect the grinding accuracy due to movement during grinding.

[0037] Referring to 10, the clamping mechanism 600 includes a first mounting base 606 and a second mounting base 607. A fixed base 601 is fastened to the first mounting base 606 by screws 608. The first mounting base 606 is provided with a slide rail 609, and a movable base 602 is provided with a groove 610 that mates with the slide rail 609. That is, both the fixed base 601 and the movable base 602 are integrated into the first mounting base 606. A third drive mechanism 603 is mounted on the second mounting base 607. The first mounting base 606 is detachably connected to the second mounting base 607, facilitating quick replacement of different molds, improving the compatibility of the types of products processed by the tool 500, reducing assembly time, and increasing production efficiency.

[0038] Refer to 10 and Figure 12The second mounting base 607 is provided with a slot 611, and the first mounting base 606 is slidably disposed in the slot 611. The slot 611 has a closed end 612 and an open end 613. The first mounting base 606 enters from the open end 613 of the slot 611 and is limited by the closed end 612. The first mounting base 606 is provided with a wedge-shaped surface 614, and the second mounting base 607 is provided with a wedge-shaped locking device, which includes a wedge block 615 and a first adjusting screw 616. The second mounting base 607 is provided with a sliding seat 617, which is close to the open end 613. The wedge block 615 is slidably disposed in the sliding seat 617, and the first adjusting screw 616 is connected to the sliding seat 617 through a nut 620 to adjust the position of the wedge block 615. During installation, after the first mounting base 606 is inserted into the slot 611, the first adjusting screw 616 is rotated to push out the wedge block 615, so that the wedge block 615 is used to press against the wedge surface 614, thereby fixing both ends of the first mounting base 606, thus fixing the first mounting base 606 in the slot 611. During disassembly, the first adjusting screw 616 is rotated in the opposite direction, and the wedge block 615 is moved into the sliding seat 617 to avoid the first mounting base 606. Then, the first mounting base 606 is moved towards the open end 613, and finally the first mounting base 606 is disengaged from the slot 611 from the open end 613, completing the disassembly.

[0039] Reference Figures 8 to 10 and Figure 12 The second mounting base 607 is provided with an adjusting slide 618 and a second adjusting screw 619. The adjusting slide 618 is slidably connected to the second mounting base 607. A third drive mechanism 603 is mounted on the adjusting slide 618. The second adjusting screw 619 is connected to the second mounting base 607 and is used to adjust the position of the adjusting slide 618. The sliding direction of the adjusting slide 618 is the same as the sliding direction of the movable base 602. By providing an adjustable adjusting slide 618, adjustments can be made according to the cutting tool 500 of different thicknesses, ensuring the flexibility of the cutting tool 500 in machining. In some embodiments, the second mounting base 607 is provided with a guide groove 621, and the adjusting slide 618 is slidably disposed in the guide groove 621.

[0040] The clamping mechanism 600 consists of a fixed base 601, a movable base 602, a third drive mechanism 603, an adjusting slide 618, and a second adjusting screw 619. By employing a combination of a first mounting base 606 detachably connected to a second mounting base 607 and an adjusting slide 618 slidably connected to the second mounting base 607, it can quickly switch workpiece molds according to different workpiece processing requirements, improving adaptability and work efficiency. Adopting a modular design, the number and functions of workstations can be quickly adjusted, fixtures support rapid replacement, and changeover time can be shortened to minutes, enabling multi-variety, small-batch production.

[0041] Reference Figures 13 to 15The grinding mechanism 300 includes a support 301, a front-rear drive mechanism 302, a left-right drive mechanism 303, an up-down drive mechanism 304, a first grinding head assembly 305, and a second grinding head assembly 306. The first grinding head assembly 305 and the second grinding head assembly 306 are arranged horizontally side by side in the left-right direction. During grinding, the cutting tool 500 is located between the first grinding head assembly 305 and the second grinding head assembly 306, so that both sides of the cutting tool 500 can be processed simultaneously. The front-rear drive mechanism 302 is used to drive the first grinding head assembly 305 and the second grinding head assembly 306 to move in the front-rear direction, that is, the front-rear drive mechanism 302 causes the first grinding head assembly 305 and the second grinding head assembly 306 to grind the cutting tool 500 in the X-axis direction. The left-right drive mechanism 303 drives the first grinding head assembly 305 and the second grinding head assembly 306 to move in the left-right direction. The first grinding head assembly 305 and the second grinding head assembly 306 move independently, that is, the left-right drive mechanism 303 causes the first grinding head assembly 305 and the second grinding head assembly 306 to move in the Z-axis direction to adjust according to the different thicknesses of the cutting tool 500. The up-down drive mechanism 304 drives the first grinding head assembly 305 and the second grinding head assembly 306 to move in the up-down direction, that is, the up-down drive mechanism 304 causes the first grinding head assembly 305 and the second grinding head assembly 306 to grind the cutting tool 500 in the Y-axis direction.

[0042] Reference Figure 14 and Figure 15 The up-and-down drive mechanism 304 includes a counterweight 307. Guide rails 308, arranged vertically, are provided on both the front and rear sides of the support 301.

The counterweight 307 is connected to the first grinding head assembly 305 and the second grinding head assembly 306 via a rope 309. The grinding mechanism 300 uses a linear slide rail 609 as a guiding device to improve guiding accuracy and stability; it uses a servo motor as an actuator to improve transmission accuracy. The grinding mechanism 300 adopts a vertical grinding feed machining method, integrating four-axis linkage (X / Y / Z axis motion + grinding wheel rotation axis) combined with a double-sided disc grinding wheel synchronous grinding method.

[0043] Reference Figure 16The unloading mechanism 400 includes a lower storage bin 401 and an unloading assembly. The unloading assembly is used to move the cutting tool 500 from the clamping mechanism 600 to the lower storage bin. The unloading assembly includes a second feeding mechanism 402, a second flipping mechanism 403, and a third conveying mechanism 404. The second feeding mechanism 402 is used to remove the cutting tool 500 from the clamping mechanism 600 and place it into the second flipping mechanism 403. The third conveying mechanism 404 removes the cutting tool 500 from the second flipping mechanism 403 and places it into the lower storage bin. The structure of the second feeding mechanism 402 is similar to that of the first feeding mechanism 204, the structure of the second flipping mechanism 403 is similar to that of the first flipping mechanism 203, and the structure of the third conveying mechanism 404 is similar to that of the second conveying mechanism 206.

[0044] In this embodiment of the fully automatic double-sided grinding equipment, the cutting tool 500 is placed horizontally in the feeding hopper 201 and the lower hopper 401 to ensure its stability. However, in the clamping mechanism 600, the cutting tool 500 is placed vertically, facilitating the grinding mechanism 300 to process both sides of the tool 500 and improving processing efficiency. The first flipping mechanism 203 and the second flipping mechanism 403 enable the tool 500 to change its orientation, allowing it to meet the needs of different workstations. The clamping mechanism 600 can position the tool 500, ensuring processing accuracy, and can quickly release and clamp the tool 500, further improving processing efficiency.
