When the second motor 59 drives the screw rod 510 to rotate, the screw rod 510 can drive the top plate 57 threadedly connected to it to move up and down, and the top plate 57 drives the push rod 56 to move up and down along the support plate 5101. Each push rod 56 corresponds to a group of two corresponding positioning rods 54. After the suction cup grabs the product parts, the motor drives the push rod 56 to move upward, and the product parts positioned in the positioning rod 54 group are pushed upward, making it easier for the suction cup to grab the parts.

[0102] The above-mentioned first guide rod 511 can guide and position the top plate 57 when the screw rod 510 rotates, so that the top plate 57 will not rotate with the screw rod 510, thereby realizing lifting and lowering when the screw rod 510 rotates, driving the top rod 56 to move upward through the bottom of the support plate 5101, and lifting the product parts between the two positioning plates 52 and the positioning rod 54 on the support plate 5101.

[0103] An air nozzle is installed on the positioning plate 52, and the air nozzle is connected to an external air source. The position of the air nozzle corresponds to the position of the positioning rod 54, and the nozzle of the air nozzle faces the product part from the upper side.

[0104] When the product is being grabbed, it will be blown with compressed air to prevent the product from grabbing double or multiple pieces.

[0105] The loading device 5 utilizes the characteristics of the product's shape and changes the positioning method to diagonal positioning. When the product's shape is different, the adjustment limit mechanism 55 on the positioning plate 52 is used to adjust the spacing between the two sides of the positioning plate 52 so that the product's diagonal force is tightened. This positioning will position the product in two directions to prevent the product from moving. At the same time, the silo adopts an independent external structure, using a square profile frame for positioning. The middle is divided into a group of positioning plates 52. The whole is positioned by the positioning plate 52. A screw 551 is installed at the upper and lower positions of the middle to fix it. When the spacing of the positioning plates 52 needs to be adjusted, the handwheel 552 on the end face of the screw 551 is turned to achieve diagonal adjustment of the product. A group of push rods 56 are installed at the bottom of the silo. When the product is grabbed, the lower push rod 56 will move upward, driving the product in the silo to move upward by 30mm. When the product is grabbed by the suction cup, the lower push rod 56 will drop to its original position. Using program control, as the products are grabbed one after another, the movement distance of the lower cover will gradually increase.

[0106] The front and rear positioning plates 52 are integrally formed, and cylindrical positioning rods 54 are mounted on them. The arc surface is used to adjust the product diagonally, so that the product can be adjusted in both directions. The two screws 551 can be used to fine-tune the positioning accurately.

The two clamping blocks 62 are close to each other and have a groove 63 that matches the shape of the mold.

[0108] A second driving mechanism for driving the clamping blocks 62 to drive the two clamping blocks 62 toward or away from each other;

[0109] The clamp assembly and the second drive mechanism are arranged on a rotating base 65, on which a lifting device 66 is provided for lifting and lowering the rotating base 65 and the clamp assembly. A third drive mechanism is provided on both sides of the rotating base 65 to drive the rotating base 65 to flip.

The sides of the two clamping blocks 62 close to each other are provided with a groove 63 adapted to the shape of the rolling abrasive tool.

[0113] A first driving mechanism for driving the clamping blocks 62 to drive the two clamping blocks 62 toward or away from each other;

[0114] The clamp assembly and the first driving mechanism are arranged on a rotating base 65, on which a lifting device 66 is provided for lifting the rotating base 65 and the clamp assembly. Second driving mechanisms are provided on both sides of the rotating base 65 to drive the rotating base 65 to flip.

[0115] In this embodiment, the bracket of the device body 1 is a direction frame, and the conveyor belt of the conveying device passes through the middle. The two clamping blocks 62 of the clamp assembly are arranged in the opposite direction of the conveying of the conveying device, that is, the clamping direction of the two clamping blocks 62 is consistent with the conveying direction of the conveying device;

[0116] The conveying device is arranged below the clamp assembly. When the conveying device conveys the rolling abrasive to the bottom of the clamp assembly, the clamp assembly is lowered to the two sides of the rolling abrasive by the lifting device 66. Then, the two clamping blocks 62 are driven to approach each other by the first driving mechanism to clamp the rolling abrasive and raise it to a certain height. Then, the rotating seat 65 is driven to flip by the second driving mechanism, which drives the rolling abrasive to flip.

[0117] The clamping block 62 is provided with an arc-shaped groove 63 that matches the shape of the rolling abrasive tool and can fit tightly against the side wall of the rolling abrasive tool. To improve stability, in some other preferred embodiments, a number of anti-slip protrusions can be provided on the side wall of the groove 63 to increase friction and prevent the rolling abrasive tool from slipping.

[0118] The clamp assembly is disposed on the rotating base 65 and can slide along the rotating base 65. The clamp assembly is driven by connecting to the first driving mechanism.

[0119] The lifting device 66 is arranged on the top of the device body 1 bracket, which can drive the rotating seat 65 to move up and down and drive the mounting seat to rotate to avoid interference with the device body 1 bracket and the conveying equipment during flipping.

[0120] like Figures 9-11 As shown, the first driving mechanism includes a bidirectional cylinder 64, the output shaft direction of the bidirectional cylinder 64 is parallel to the conveying direction of the rolling and polishing tool, and the two clamping blocks 62 are respectively installed at the two output ends of the bidirectional cylinder 64. The two clamping blocks 62 are driven to move closer or farther away by the bidirectional cylinder 64, and the bidirectional cylinder 64 is fixedly connected to the rotating seat 65.

[0121] The first driving mechanism is a bidirectional cylinder 64 having two output ends in opposite directions. Each output end is connected to a clamping block 62. The bidirectional cylinder 64 drives the two clamping blocks 62 to move closer to or away from each other, thereby achieving the clamping and loosening of the rolling abrasive.

[0122] In order to improve the efficiency of flipping, in this embodiment, two sets of clamp assemblies are provided, and the two sets of clamp assemblies are arranged side by side on the rolling abrasive conveying device and installed on the rotating seat 65;

[0123] Correspondingly, two bidirectional cylinders 64 are provided, which are respectively arranged on both sides of the bracket of the device body 1, and each bidirectional cylinder 64 corresponds to a set of clamp components.

[0124] Two sets of clamp assemblies are provided, and cooperate with the bidirectional cylinder 64 to realize the flipping of the two sets of rolling and throwing abrasive tools.

[0125] like Figures 9-11 As shown, the lifting device 66 includes two lifting seats 661, and the two lifting seats 661 are arranged on both sides of the bracket of the device body 1;

[0126] The two ends of the rotating seat 65 are respectively connected to the two lifting seats 661 for rotation. The second driving mechanism is installed on the outside of the lifting seat 661 to drive the rotating seat 65.

[0127] It also includes a lifting cylinder 662 and a fixed seat 663. The fixed seat 663 is fixedly connected to the top of the bracket of the device body 1. The lifting cylinder 662 is arranged on the top of the fixed seat 663 in the vertical direction, and the output end of the lifting cylinder 662 is fixedly connected to the fixed seat 663. A movable seat 664 is fixedly connected to the cylinder body of the lifting cylinder 662. Both sides of the bottom of the movable seat 664 are fixedly connected with a second slide rod 665. The second slide rod 665 passes through the fixed seat 663 and is fixedly connected to the lifting seat 661. The second slide rod 665 is slidably connected to the fixed seat 663.

[0128] The above-mentioned fixed seat 663 is fixedly connected to the top of the bracket of the device body 1, and the output end of the lifting cylinder 662 is fixed on the fixed seat 663. The cylinder body of the lifting cylinder 662 is movable. When the lifting cylinder 662 is extended, the output end of the lifting cylinder 662 is fixed, and its cylinder body drives the movable seat 664 to move upward, and through the movable seat 664, drives the second sliding rods 665 on both sides to move upward, and through the second sliding rods 665, drives the lifting seat 661 to move upward, thereby realizing the lifting of the rolling abrasive, which is convenient for flipping it.

[0129] The second driving mechanism is a servo motor 67 . The servo motor 67 is fixedly connected to the lifting seat 661 , and an output end thereof passes through the lifting seat 661 and is fixedly connected to the rotating seat 65 .

[0130] The second driving mechanism is a servo motor 67. When the rolling abrasive tool is turned over and placed back on the conveying device, the rotating base 65 needs to be lifted up again and reset.

[0131] Second guide rods 68 are provided on both sides of the lifting seat 661 , and the second guide rods 68 are fixedly connected to the bracket of the device body 1 .

[0132] In some other preferred embodiments, each clamping block 62 is provided with two grooves 63 .

[0133] Each clamping block 62 is provided with two grooves 63 , that is, each clamping block 62 can clamp two rolling abrasives at a time, thereby increasing the number of rolling abrasives that can be turned over each time, thereby improving work efficiency.

[0134] A position sensor is provided on the bracket of the device body 1 to sense the position of the rolling grinding tool corresponding to the position of the clamping assembly. The position sensor is electrically connected to the bidirectional cylinder 64, the servo motor 67 and the lifting cylinder 662.

[0135] By setting a position sensor, which is electrically connected to the switch control system of the conveying equipment, the position of the rolling and throwing abrasive tool can be sensed in real time;

[0136] 1. When the roller-throwing abrasive is transported to the position corresponding to the fixture assembly by the conveying equipment, the sensor sends a signal to the control system to control the conveying equipment to stop conveying;

[0137] Second, the lifting cylinder 662 is controlled to operate (retract), driving the lifting seat 661, the rotating seat 65 and the clamp assembly to move downward until the two clamping blocks 62 of the clamp assembly are located on both sides of the rolling polishing tool;

[0138] 3. Then, the bidirectional cylinder 64 is controlled to operate (contract), driving the clamping blocks 62 on both sides to clamp the rolling and polishing tool;

[0139] 4. After clamping, the lifting cylinder 662 operates (extends), driving the clamp assembly, the rotating seat 65 and the lifting seat 661 to move up to a certain height (as long as they do not interfere with the conveying equipment);

[0140] 5. Then control the servo motor 67 to operate, driving the rotating seat 65 and the clamp assembly to flip, causing the rolling abrasive to flip accordingly;

[0141] 6. Then the lifting cylinder 662 operates (contracts), driving the rotating seat 65 and the clamp assembly back to their original positions;

[0142] 7. At this time, the bidirectional cylinder 64 is controlled to extend, driving the clamping block 62 to release the rolling and polishing tool;

[0143] 8. Repeat the process, reset the device, and wait for the next action.

[0144] During the machining process, the roller-throwing abrasives are loaded onto the conveyor belt (they have two open sides, the top and the bottom, and require separate loading). Once transported to the bottom of the turnover area, a sensor signals the abrasive and pallet to pause, then separate from the conveyor belt and secure the pallet beneath the flip mechanism. The flip mechanism is then designed to position and clamp the circular jaws around the perimeter, separate from the pallet, rise to approximately the height of two abrasives, flip, and then descend until it is positioned and positioned with the pallet. Finally, it lands on the conveyor belt along with the pallet for delivery. The entire process is controlled by pneumatic cylinders and motors, each operating step.

[0145] Emergency stop switches are provided at positions on the device body 1 corresponding to the liquid adding device 7, the film loading device 5, the feeding device 4 and the turning mechanism. The emergency stop switches are electrically connected to the main control mechanism.

[0146] Position sensors are provided on the device body 1 at positions corresponding to the liquid adding device 7, the film loading device 5, the feeding device 4 and the flipping mechanism. The position sensors are electrically connected to the main control mechanism. The position of the mold tray 3 is sensed by the position sensors, and the corresponding operation is controlled by the main control mechanism.

[0147] Turnover boxes 8 are provided on both sides of the transmission direction of the transmission mechanism 2 for storing the grinding tools.

[0148] The process utilizes a linear transfer design, enabling automatic loading, liquid addition, and sheet removal throughout the entire conveyor belt process, with subsequent automatic flipping. The machine moves repeatedly at the same workstation, performing, for example, 10 loading cycles, followed by 10 cycles of loading, liquid addition, and valve removal. After loading, the machine moves to the next step, where the lid is manually installed. In the next step, the automatic flip mechanism activates, using a pneumatic cylinder to tighten the mold, raising the mold by two levels. The rotary cylinder then rotates the mold 180°, lowering the mold by two levels, releasing the clamping cylinder, and moving to the next process to load the abrasive and product on the other side of the mold. This reduces the cycle time for repeated steps.

[0149] 1. The production line adopts linear and chain drive design, and the molds are placed as a whole. 10 molds can be loaded at the same time. After turning over, it is equivalent to loading 20 molds at the same time, which improves efficiency.

[0150] 2. Automatically flip the mold, eliminating manual handling and reducing workers' labor intensity;

[0151] 3. Aluminum alloy square steel is used as a fixed bracket, and turnover boxes 8 are used at both ends to alternately rotate the mold positioning plate up and down. It has good versatility for molds of different dimensions.

[0152] 4. Furthermore, the tray above the chain is designed to connect two sets of molds in parallel, with socket positioning blocks 35 installed on top for positioning. The upper opening is large, and the lower opening is small. When the molds and mold holder 33 vary in size, the positioning blocks 35 decrease in size as they move downwards, ensuring precise positioning. This prevents positioning deviations due to mold size variations, which could affect the quality of subsequent rolling and polishing.

[0153] 1. The support plate positioning mold structure is simple and practical, which can solve the positioning error of different mold sizes.

[0154] 2. At the same process position, the operation is performed 10 times to reduce the step turnover time and improve the product assembly efficiency.

[0155] 3. Each process on the entire assembly line is equipped with an emergency stop device to prevent equipment operation deviations caused by signal failures in machine tool operation, and to stop the machine in time to reduce equipment damage accidents.
