Abstract
Description
Technical Field
[0001] This invention relates to the field of egg beater technology, and more particularly to an egg beater assembly device. Background Technology
[0002] An egg beater is used to thoroughly mix egg whites and yolks into an egg liquid, or to beat egg whites and yolks separately until foamy. It can easily and quickly mix egg whites and yolks into an egg liquid. When preparing large quantities of egg liquid or foaming, using an egg beater can be faster and save manpower.
[0003] There are two common types of egg beaters: manual and electric. However, regardless of the type, all egg beaters need a mixing head, which is essentially a simple manual egg beater. Usually, for ease of gripping, a plastic or wooden handle is added. The mixing head is generally formed by bending multiple steel wires (stainless steel). To limit and fix the position of each wire, it usually includes a perforated plate and a spring. Both ends of the wires pass through the perforated plate to restrict their position, and the spring then tightens and fixes all the wire ends. See the simplified structural diagram of an egg beater. Figure 1 .
[0004] Currently, the assembly of egg beaters is mostly done by hand. Among them, the assembly of the spring is particularly difficult. Many manufacturers use wire wrapping and binding as an alternative to directly assembling the spring. However, the wire wrapping and binding method may result in the wire not being tied tightly. Moreover, after the wire is wrapped and bound, the handle of the beater head is prone to deformation to a certain extent, which requires correction. This is time-consuming, labor-intensive, and inefficient. Summary of the Invention

[0055] Egg beater 90, steel wire 91, perforated plate 92, spring 93. Detailed Implementation
[0056] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0057] like Figures 1-19 As shown, this invention discloses an assembly device for an egg beater 90, which includes a controller, a frame 10, a wire bending mechanism 20, an adjustment mechanism 30, a gripping mechanism 40, a first pushing mechanism 71, a perforated plate feeding mechanism 62, a spring feeding mechanism 61, an assembly mechanism 50, a second pushing mechanism 72, a material ejection mechanism 81, and a material unloading mechanism 82. Along the moving direction of the wire 91, the wire bending mechanism 20, the adjustment mechanism 30, the first pushing mechanism 71, the material ejection mechanism 81, the assembly mechanism 50, and the second pushing mechanism 72 are sequentially installed on the frame 10. The gripping mechanism 40 is mounted on the frame 10 and moves the wire 91, straightened by the adjustment mechanism 30, to the assembly mechanism 50. The perforated plate feeding mechanism 62 is located on one side of the assembly mechanism 50, and the material unloading mechanism 82 is located on the other side of the assembly mechanism 50. The spring feeding mechanism 61 is located on the side of the assembly mechanism 50 closest to the second pushing mechanism 72.
[0058] The wire bending mechanism 20 is used to bend the straight steel wire 91 fed onto it into a U-shape. An automatic wire feeding device can be set up to automatically feed the wire bending mechanism 20. The automatic wire feeding device can be a wire straightening and cutting machine, which is connected to a controller to control the output. The wire bending mechanism 20 includes a positioning channel 21, a wire pushing assembly, a first pressing die 23, a second pressing die 24, and a wire bending drive 25. The positioning channel 21 is used to position the fed steel wire 91, and a wire outlet 211 communicating with the outside is provided at the top of the positioning channel 21.
[0059] The wire pushing assembly is used to push the steel wire 91 out of the positioning channel 21. Two sets of the wire pushing assembly are provided, each including a wire pushing cylinder 221, a baffle 222, and two push blocks 223. The wire pushing cylinder 221 is connected to a controller. The wire pushing cylinder 221 drives the baffle 222 and push blocks 223 to move up and down synchronously. A clearance opening 212, which cooperates with the push blocks 223, is provided at the bottom of the positioning channel 21. Under normal conditions, the push rod of the wire pushing cylinder 221 is in a retracted state. At this time, the push blocks 223 are placed in the clearance opening 212, which does not interfere with the movement of the steel wire 91 in the positioning channel 21, facilitating the feeding of the steel wire 91. Simultaneously, the baffle 222 also covers the wire outlet 211 to prevent the steel wire 91 from falling out of the outlet 211. A detection sensor can be installed at the end of the positioning channel 21 to detect whether the steel wire 91 has been fed into the correct position. The detection sensor is connected to the controller. After the detection sensor detects the steel wire 91, the feeding of the steel wire 91 stops. Then, the push rod of the push cylinder 221 is pushed upward, the baffle 222 rises and no longer blocks the wire outlet 211, and the push block 223 rises to push the steel wire 91 in the positioning channel 21 out of the wire outlet 211. At this time, the push block 223 also supports the steel wire 91. In this case, four push blocks 223 are provided to ensure that the steel wire 91 is placed stably.
[0060] The first die 23 is an arched punch, locked to the frame 10, and located on the side of the positioning channel 21 near the adjusting mechanism 30. The second die 24 is an arched die that cooperates with the first die 23. The bending drive 25 drives the second die 24 to move relative to the first die 23. The bending drive 25 is a cylinder connected to a controller. The moving direction of the second die 24 is perpendicular to the length direction of the positioning channel 21, and it is best if the line connecting the first die 23 and the second die 24 is aligned with the midpoint of the positioning channel 21 to ensure that the steel wire 91 is bent into a symmetrical U-shape. Under normal conditions, the second die 24 is located on the side of the positioning channel 21 away from the adjusting mechanism 30. The second die 24 can pass through the positioning channel 21. When the second die 24 passes through the positioning channel 21, it blocks the positioning channel 21 to prevent the steel wire 91 from being fed. Under the power of the bending drive 25, the first die 23 and the second die 24 work together to quickly bend the straight steel wire 91 into a U-shape. To ensure reliable bending of the steel wire 91, first rollers 26 are provided on both sides of the second die 24 for guiding and limiting the steel wire 91. The circumference of the first roller 26 is provided with a first groove 261. The bottom width of the first groove 261 is adapted to the diameter of the steel wire 91, and the groove wall of the first groove 261 is a guide slope for guiding the steel wire 91 to the bottom of the groove. When the second die 24 pushes the steel wire 91 to move towards the first die 23 and bends it, the steel wire 91 can be stuck into the first groove 261, which both guides and limits it. After the U-shaped steel wire 91 is formed, the first groove 261 can also play a certain limiting role to prevent the U-shaped steel wire 91 from falling off.
[0061] The U-shaped steel wire 91 has a relatively long end. After the U-shaped steel wire 91 is formed, its end may droop slightly under the action of gravity, which will affect the accuracy of the gripping mechanism 40 in gripping the end of the U-shaped steel wire 91, and thus cause misalignment between the end of the U-shaped steel wire 91 and the hole position on the perforated plate 92. In order to prevent this problem, an adjustment mechanism 30 is provided for straightening the end of the U-shaped steel wire 91 to ensure that the U-shaped steel wire 91 gripped by the gripping mechanism 40 is in a uniform posture. Specifically, the adjustment mechanism 30 includes a parallel platform 31 and leveling components placed on both sides of the parallel platform 31. The parallel platform 31 is set between the wire bending mechanism 20 and the first pushing mechanism 71 and is close to the first pressing mold 23. The first pressing mold 23 can be directly locked onto the parallel platform 31. The two side walls of the parallel platform 31 are parallel to each other and flush with the edge of the first pressing mold 23. Theoretically, the end of the bent steel wire 91 is abutting against the side wall of the parallel platform 31.
[0062] The leveling assembly includes a first linear movement module 32, a clearance module 34, and a second roller 33. The first linear movement module 32 is connected to a controller and is powered by a cylinder. Linear movement modules are existing mature technologies and will not be described in detail here. The first linear movement module 32 drives the clearance module 34 to move along the length of the parallel platform 31, while the clearance module 34 drives the second roller 33 to move toward the parallel platform 31. The second roller 33 can press against the side wall of the parallel platform 31. A second groove 331 is provided on the circumference of the second roller 33. The bottom width of the second groove 331 is adapted to the diameter of the steel wire 91, and the groove wall of the second groove 331 is a guide slope.
[0063] The obstacle avoidance module 34 includes an obstacle avoidance cylinder 341, a first hinge seat 342, a second hinge seat 343, a third hinge seat 344, a first swing arm 345, a second swing arm 346, and a third swing arm 347. The obstacle avoidance cylinder 341 is connected to a controller. The first hinge seat 342 is fixed in position relative to the seat of the obstacle avoidance cylinder 341, and the obstacle avoidance cylinder 341 drives the second hinge seat 343 to move up and down. One end of the first swing arm 345 is hinged to the first hinge seat 342, and the other end of the first swing arm 345 is hinged to the middle of the third hinge seat 344. One end of the second swing arm 346 is hinged to the middle of the first swing arm 345, and the other end of the second swing arm 346 is hinged to one end of the second hinge seat 343. One end of the third swing arm 347 is hinged to the other end of the second hinge seat 343, and the other end of the third swing arm 347 is hinged to one end of the third hinge seat 344. The second roller 33 is rotatably connected to the other end of the third hinge seat 344. With this configuration, when the avoidance cylinder 341 is in the retracted state, the avoidance module 34 and the second roller 33 will not interfere with the bending of the steel wire 91 (during the bending process of the steel wire 91, its end moves from above the positioning channel 21 to the side of the parallel platform 31). After the steel wire 91 is bent, the push rod of the avoidance cylinder 341 extends, and at this time the second roller 33 will press against the side wall of the parallel platform 31.
[0064] Before the second roller 33 presses against the side wall of the parallel platform 31, the first linear movement module 32 positions the avoidance module 34 near the first pressing mold 23 on the parallel platform 31. At this point, the second roller 33 presses against the side wall of the parallel platform 31. Because the downward offset of the two ends of the U-shaped steel wire 91 is small at this point, it can be ensured that both ends of the U-shaped steel wire 91 fall into the second groove 331. Afterward, the first linear movement module 32 pushes the avoidance module 34 to move, and the second roller 33 travels on the parallel platform 31. Under the limiting and guiding action of the second groove 331, the two ends of the U-shaped steel wire 91 are flattened and can be in a uniform posture. It should be noted that the ends of the U-shaped steel wire 91 extend beyond the parallel platform 31 in the length direction to ensure that the gripping mechanism 40 can grip it.
[0065] The gripping mechanism 40 includes a second linear motion module 41, a first lifting cylinder 42, two first horizontal cylinders 43, two second horizontal cylinders 44, two first clamping plates 45, and two second clamping plates 46. The second linear motion module 41 is based on a motor and is a mature existing technology, so it will not be described in detail. The second linear motion module 41, the first lifting cylinder 42, the first horizontal cylinders 43, and the second horizontal cylinders 44 are all connected to a controller. The second linear motion module 41 drives the first lifting cylinder 42 to move back and forth between the wire bending mechanism 20 and the assembly mechanism 50. The first lifting cylinder 42 drives the two first horizontal cylinders 43 to move up and down synchronously. The first horizontal cylinders 43, the second horizontal cylinders 44, the first clamping plates 45, and the second clamping plates 46 correspond one-to-one. The first horizontal cylinders 43 drive the second horizontal cylinders 44 and the first clamping plates 45 to move horizontally synchronously. The two first horizontal cylinders 43 are arranged opposite each other and move synchronously. The second horizontal cylinder 44 drives the second clamping plate 46 to move relative to the first clamping plate 45. The two first clamping plates 45 are parallel to each other, and the first clamping plate 45 and the second clamping plate 46 are parallel to each other. The first clamping plate 45 and the second clamping plate 46 cooperate to clamp the end of the U-shaped steel wire 91. In order to prevent the clamped steel wire 91 from falling off, the first clamping plate 45 and / or the second clamping plate 46 are provided with a slot 47 for limiting the steel wire 91. Because the end of the steel wire 91 is straightened by the adjusting mechanism 30, it can be in a uniform posture for the gripping mechanism 40 to grip, thus ensuring that the end of the steel wire 91 falls into the slot 47.
[0066] The assembly mechanism 50 is equipped with a rotary positioning component 51, a gathering component 52, and a spring positioning station 53. The rotary positioning component 51 is used to position and place the perforated plate 92 and control its rotation. Specifically, the rotary positioning component 51 includes a rotary motor 511, a hollow rotating shaft 512, and a positioning table 513. The rotary motor 511 is connected to a controller. The hollow rotating shaft 512 is rotatably connected to the frame 10 and is limited, that is, the hollow rotating shaft 512 can only rotate on its own axis and cannot move. The rotary motor 511 drives the hollow rotating shaft 512 to rotate. The positioning platform 513 is located at one end of the hollow rotating shaft 512 near the first propulsion mechanism 71. The positioning platform 513 is provided with a positioning groove 514 that matches the shape of the perforated plate 92. Both the upper and lower walls of the positioning groove 514 are provided with elastic telescopic members 515 to prevent the perforated plate 92 from falling out of the positioning groove 514. The groove wall of the positioning groove 514 is provided with holes for installing the elastic telescopic members 515. The end of the elastic telescopic member 515 extending out of the hole is designed as a spherical surface. The elastic telescopic member 515 can be made of elastic rubber. With this configuration, when the perforated plate 92 is pushed into the positioning groove 514, the elastic telescopic member 515 is compressed by force, and the spherical surface retracts into the hole. The perforated plate 92 can be inserted into the positioning groove 514 to the bottom of the groove. After the external force pushing the perforated plate 92 is removed, the elastic telescopic member 515 springs back and extends, thereby preventing the perforated plate 92 from falling out.
[0067] A mounting platform 516 is provided in the middle section of the hollow rotating shaft 512. Two slide rails 517 are symmetrically arranged in the mounting platform 516, and the two slide rails 517 are on the same straight line. The slide rails 517 are connected to the inner cavity of the hollow rotating shaft 512. Two sets of gathering components 52 are provided, each corresponding to one of the slide rails 517. The gathering component 52 includes a gathering cylinder 521, a pusher 522, a connector 523, and a pressure block 524. The gathering cylinder 521 is connected to a controller. The gathering cylinder 521 is locked on the frame 10. The gathering cylinder 521 drives the pusher 522 to move relative to the mounting platform 516. An open-loop retainer 525 is provided on the pusher 522. The pressure block 524 is slidably connected in the slide rail 517. When the pressure blocks 524 corresponding to the two gathering components 52 abut against each other, a gathering opening 526 is formed between the two pressure blocks 524. The diameter of the gathering opening 526 decreases along the direction from the positioning table 513 to the mounting table 516, and the minimum diameter of the gathering opening 526 is not greater than the inner diameter of the spring 93, so as to ensure that the ends of all the steel wires 91 are gathered into a handle, and the handle can be inserted into the middle cavity of the spring 93. The connecting piece 523 is a screw, the threaded end of which is threadedly connected to the pressure block 524. The other end of the connecting piece 523 is provided with a collet 527 (i.e., the end cap of the screw), and the collet 527 extends out of the mounting table 516. Under normal conditions, the gathering cylinder 521 is in a retracted state, and the clamp 527 is positioned in the open-loop clamp 525. If the hollow shaft 512 rotates at this time, the clamp 527 can pass through the open-loop clamp 525, meaning the gathering cylinder 521 and the pusher 522 will not interfere with the rotation of the hollow shaft 512. When the hollow shaft 512 rotates 180°, it indicates that the perforated plate 92 and the steel wire 91 are connected. The clamp 527 is then positioned in the open-loop clamp 525 again. At this time, the gathering cylinder 521 can push the pressure block 524 to slide, forming the gathering opening 526, thus completing the gathering of all the ends of the steel wires 91. Furthermore, to facilitate gathering, the inner cavity in the hollow shaft 512 located between the positioning table 513 and the mounting table 516 is defined as the guide cavity 518. The diameter of the guide cavity 518 decreases along the direction from the positioning table 513 to the mounting table 516.
[0068] The spring feeding mechanism 61 is used to feed the springs 93 into the spring positioning station 53 in a uniform posture. The spring positioning station 53 is a groove. The spring feeding mechanism 61 includes a hopper 611, a baffle plate 612, a roller 613, and a feeding drive assembly 615. The roller 613 is located at the bottom outlet of the hopper 611. The roller 613 is rotatably connected to and limited by the hopper 611, meaning that the roller 613 can only rotate and cannot move. The feeding drive assembly 615 drives the roller 613 to rotate. The feeding drive assembly 615 can be a motor and a transmission pair, such as a gear set or a pulley set. The motor of the feeding drive assembly 615 is connected to a controller. Several material grooves 614 are evenly distributed on the circumference of the roller 613. The groove shape of the material grooves 614 is adapted to the shape of the springs 93. When the roller 613 rotates, the material grooves 614 pass over the spring positioning station 53 in sequence and circulate. When the material grooves 614 pass the spring positioning station 53, the groove openings of the material grooves 614 face the spring positioning station 53, and the springs 93 fall into the spring positioning station 53, realizing the positioning of the springs 93. The baffle plate 612 partially surrounds the circumference of the roller 613 to prevent the springs 93 from falling out of the material grooves 614.
[0069] The perforated plate feeding mechanism 62 is used to feed the perforated plate 92 into the positioning groove 514 on the rotary positioning assembly 51 in a uniform posture. The perforated plate feeding mechanism 62 includes a vibratory feeder 63, a perforated plate 92 positioning assembly, and a perforated plate 92 gripping assembly. The vibratory feeder 63 is used to output the perforated plate 92 in a uniform posture, which is prior art and will not be described in detail. The vibratory feeder 63 is connected to a controller to control the discharge. The perforated plate 92 positioning assembly is located at the discharge port of the vibratory feeder 63. The perforated plate 92 positioning assembly includes a second gripper cylinder 641 and two second grippers 642. The second gripper cylinder 641 is connected to the controller. The two second grippers 642 are respectively locked onto the two gripper arms of the second gripper cylinder 641. The second gripper cylinder 641 can drive the two second grippers 642 to move closer or further apart. Each of the two second clamping blocks 642 is provided with a first limiting groove 643 for restricting the perforated plate 92. The two first limiting grooves 643 cooperate to form a limiting channel through which the perforated plate 92 can pass. This limiting channel is connected to the discharge port of the vibratory feeder 63, so that the perforated plate 92 output by the vibratory feeder 63 can maintain its original posture when transitioning into the limiting channel. Each of the second clamping blocks 642 is provided with a baffle 644 to prevent the perforated plate 92 from falling out of the limiting channel.
[0070] The perforated plate 92 gripping assembly includes a third horizontal cylinder 651, a fourth horizontal cylinder 652, and a gripping or adsorption component 653 for gripping the perforated plate 92. The third horizontal cylinder 651 and the fourth horizontal cylinder 652 are connected to a controller. Whether the gripping component and the adsorption component 653 are connected to the controller depends on the actual product selected. For example, if the gripping component is an electric clamp and the adsorption component 653 is an electromagnet, then the gripping component and the adsorption component 653 need to be connected to the controller. Of course, the adsorption component 653 can also be a permanent magnet or other component that can adsorb the perforated plate 92 without control. The third horizontal cylinder 651 drives the fourth horizontal cylinder 652 to move back and forth between the perforated plate 92 positioning assembly and the rotary positioning assembly 51. The fourth horizontal cylinder 652 drives the gripping or adsorption component 653 to move relative to the perforated plate 92 positioning assembly.
[0071] A clearance groove 645 is provided on the limiting channel to avoid the gripping or adsorption component 653. When gripping the perforated plate 92, the third horizontal cylinder 651 retracts, so that the gripping or adsorption component 653 is directly facing the clearance groove 645. Then, the fourth horizontal cylinder 652 extends, and the gripping or adsorption component 653 extends into the clearance groove 645 and grips the perforated plate 92. After that, the second gripper cylinder 641 opens, so that the second gripper block 642 will not interfere with the movement of the perforated plate 92. Subsequently, the fourth horizontal cylinder 652 retracts, the third horizontal cylinder 651 extends, and the fourth horizontal cylinder 652 extends again. The perforated plate 92 on the gripping or adsorption component 653 overcomes the resistance of the elastic telescopic component 515 and is inserted into the positioning groove 514. The gripping or adsorption component 653 releases the perforated plate 92, and the fourth horizontal cylinder 652 retracts, thus completing the loading of the perforated plate 92. Of course, when the adsorption element 653 does not need to be controlled, the adsorption force between the perforated plate 92 and the adsorption element 653 is less than the resistance of the elastic telescopic element 515. When the fourth horizontal cylinder 652 retracts, the perforated plate 92 can detach and remain in the positioning groove 514, thereby realizing the feeding of the perforated plate 92.
[0072] The first propulsion mechanism 71 includes a third linear motion module 711, a second lifting cylinder 712, a first gripper cylinder 713, a support plate 714, and two first clamping blocks 715. The third linear motion module 711 is based on a motor and is existing technology, so it will not be described in detail here. The third linear motion module 711, the second lifting cylinder 712, and the first gripper cylinder 713 are all connected to a controller. The third linear motion module 711 drives the second lifting cylinder 712 to move back and forth between the parallel platform 31 and the positioning platform 513. The second lifting cylinder 712 drives the support plate 714 and the first gripper cylinder 713 to move up and down synchronously. The two first clamping blocks 715 are respectively locked on the two gripping arms of the first gripper cylinder 713. The first gripper cylinder 713 drives the two first clamping blocks 715 to move closer or further apart synchronously. A guide groove 716 is provided on the first clamping block 715, and the slots of the guide grooves 716 on the two first clamping blocks 715 are arranged opposite each other.
[0073] The second propulsion mechanism 72 includes a fourth linear motion module 721 and a push tube 722. The fourth linear motion module 721 is based on a motor and is existing technology, so it will not be described in detail here. The fourth linear motion module 721 is connected to a controller. The fourth linear motion module 721 drives the push tube 722 to move relative to the spring positioning station 53. The outer diameter of the push tube 722 is adapted to the outer diameter of the spring 93 to facilitate pushing the spring 93. The inner diameter of the push tube 722 is adapted to the inner diameter of the spring 93 to avoid the handle. The handle can be inserted into the inner cavity of the push tube 722 to avoid the handle. To facilitate the assembly of spring 93, the inner cavity of hollow shaft 512 located on the side of mounting platform 516 away from positioning platform 513 is defined as limiting cavity 519. The diameter of limiting cavity 519 is matched with the outer diameter of spring 93. This setting makes it easy to push spring 93 towards handle without deforming or twisting, maintaining a relatively straight state, which is conducive to spring 93 being fitted and clamped on the outer circumference of handle.
[0074] After the steel wire 91 is bent and straightened, the gripping mechanism 40 grips both ends of the U-shaped steel wire 91. Then, the adjusting mechanism 30 and the bending mechanism 20 are reset, and the U-shaped steel wire 91 can be taken out. Then, the two first horizontal cylinders 43 also act synchronously, so that the two ends of the U-shaped steel wire 91 are brought closer to each other, ready to be inserted into the hole on the perforated plate 92. After the gripping mechanism 40 moves the taken-out U-shaped steel wire 91 a certain distance towards the positioning table 513, that is, after the U-shaped steel wire 91 is placed above the first pushing mechanism 71, the support plate 714 rises and clamps the U-shaped steel wire 91. The two ends of the U-shaped steel wire 91 can be inserted into the guide groove 716. In this way, the included angle between the two ends of the U-shaped steel wire 91 can be adjusted, thereby ensuring that the ends of the steel wire 91 can be smoothly inserted into the hole. The gripping mechanism 40 and the first propulsion mechanism 71 operate synchronously. The two ends of the U-shaped steel wire 91 pass sequentially through the perforated plate 92, the guide cavity 518, and the open convergence port 526. At this point, even if the gripping mechanism 40 and the first propulsion mechanism 71 release, the U-shaped steel wire 91 will not fall. During the movement of the U-shaped steel wire 91, its arched top can abut against the support plate 714, thus preventing it from falling back.
[0075] In this case, the perforated plate 92 has ten holes, which means that five steel wires 91 need to be threaded through. After one steel wire 91 is threaded through, when the gripping mechanism 40 is gripping another steel wire 91, the support plate 714 can support the assembled steel wire 91 to a certain extent to prevent it from falling. At the same time, the positioning table 513 rotates to make way for other holes that have not yet been threaded with steel wires 91. Then, the steel wires 91 are assembled in the same way as above until all holes are threaded with steel wires 91. After all the steel wires 91 are assembled, the gathering opening 526 closes, and the ends of all the steel wires 91 are pressed together to form a handle. Then, the first pushing mechanism 71 presses against the top of the arch of the steel wires 91, and the second pushing mechanism 72 pushes the spring 93 on the spring positioning station 53 into the limiting cavity 519, so that the end of the handle is inserted into the inner cavity of the spring 93. After that, the gathering opening 526 opens, and the second pushing mechanism 72 continues to push until the handle passes out of the inner cavity of the spring 93, thus completing the assembly of the egg beater 90.
[0076] The ejection mechanism 81 operates after the whisk 90 is assembled, used to remove the perforated plate 92 from the positioning slot 514 to assist the whisk 90 in unloading material. The ejection mechanism 81 includes a fifth linear motion module 811, a third gripper cylinder 812, and two insert blocks 813. The fifth linear motion module 811 is based on a cylinder and is existing technology, so it will not be described in detail. The fifth linear motion module 811 and the third gripper cylinder 812 are connected to a controller. The fifth linear motion module 811 drives the third gripper cylinder 812 to move back and forth between the positioning table 513 and the first pushing mechanism. The two insert blocks 813 are respectively placed on both sides of the positioning table 513, and are respectively locked onto the two gripping arms of the third gripper cylinder 812. The third gripper cylinder 812 drives the two insert blocks 813 to move closer together or further apart. The positioning platform 513 has slots 541 that correspond one-to-one with the inserts 813. These slots 541 are connected to the positioning grooves 514, and a stepped surface 542 is formed between the slots 541 and the positioning grooves 514 to restrict the perforated plate 92, so as to prevent the perforated plate 92 from falling into the slots 541. After the whisk 90 is assembled, the first pushing mechanism 71 is reset, the inserts 813 are inserted into the slots 541, and then the fifth linear moving module 811 drives the inserts 813 to move toward the first pushing mechanism 71, so that the perforated plate 92 can be pried out of the positioning grooves 514. Then the unloading mechanism 81 is reset. At this time, the handle of the whisk 90 is partially retained in the inner cavity of the hollow rotating shaft 512, and the whisk 90 will not fall off, so that it can be grabbed by the unloading mechanism 82.
[0077] The unloading mechanism 82 is located near the rotary positioning assembly 51. It includes a fifth horizontal cylinder 821, a rotary cylinder 822, a telescopic cylinder 823, and a pneumatic clamp 824 for holding the whisk 90. All four cylinders are connected to a controller. The fifth horizontal cylinder 821 drives the rotary cylinder 822 to move horizontally, the rotary cylinder 822 drives the telescopic cylinder 823 to swing, and the telescopic cylinder 823 drives the pneumatic clamp 824 to extend and retract. After the whisk 90 is moved a certain distance from the positioning table 513 by the unloading mechanism 81, the rotary cylinder 822 actuates, causing the pneumatic clamp 824 to face the whisk 90. Then, the telescopic cylinder 823 extends, and the pneumatic clamp 824 clamps the whisk 90. Finally, the fifth horizontal cylinder 821 extends, and the whisk 90 is pulled out, leaving the rotary positioning assembly 51, thus completing the unloading process. A material frame can be set next to the unloading mechanism 82 to hold the unloaded egg beater 90. At this time, the action of the unloading mechanism 82 to put down the egg beater 90 is adaptively adjusted according to the placement position of the material frame.
