Referring to the invention patent with the application number CN202110081511.0, due to the design limitations of the rotary table structure, each mechanism can only start to perform actions after the product rotates to the corresponding station, and the waiting time of the product at the station is too long during the execution of the steps, and the coordination between processes cannot reach the optimum. Furthermore, the operation time of a single ceramic mold in the mold opening machine is as high as 25 s to 27 s, which has a great impact on the efficiency of the entire technological production line. Therefore, the present invention has developed a blank taking mechanism based on a ceramic multi-lobe mold to solve the problems existing in the prior art. Summary of the Invention

[0003] The object of the present invention is to provide a blank taking mechanism based on a ceramic multi-lobe mold to solve the problem that the coordination between each process in a rotary mold opening machine in the prior art cannot reach the optimum, resulting in low mold opening efficiency and affecting the technological process.

[0028] An inner die cleaning mechanism is arranged below the blank taking station. The inner die cleaning mechanism has a brush rotating axially. The axis of the brush is parallel to the mold closing line and realizes lifting through the drive of a cylinder.

[0029] Preferably, the rotating mechanism includes a rotating table and a rotating motor for driving the rotation of the rotating table; the mold is placed on the rotating table, and two second through holes are arranged at positions on the lower end face of the mold exposed from the end face of the rotating table in the radial direction of the lower end face of the mold.

[0030] The inductor adopts a laser ranging sensor and is arranged directly below any position point on the rotation path of the first through hole along with the rotating table;

[0031] The mold positioning unit further includes a lifting member for realizing precise positioning. The lifting member is arranged directly below any position point on the rotation path of the second through hole along with the rotating table; when the inductor is aligned with the first through hole, the lifting member is aligned with the second through hole, and precise positioning is realized by inserting the lifting member into the second through hole.

[0032] Preferably, the rotating mechanism is arranged at the hole searching station corresponding to the carrier table, positioning seats are arranged at the mold opening station and the reserved station corresponding to the carrier table, and a belt conveyor line A is arranged at the mold closing station corresponding to the carrier table;

[0038] Compared with the prior art, the advantages of the present invention are:

[0039] (1) The present invention is based on a mold linear transport unit and adopts two sets of inner mold grabbing mechanisms and clamping mechanisms to cooperate in executing actions, so that the average working time of a single ceramic mold is reduced to about 10 seconds, which greatly improves the work efficiency; the motion trajectories of the two sets of clamping mechanisms are symmetrically arranged, and there is no interference between their reciprocating motions, and the synergy is high, which makes it possible to shorten the working time.

[0040] (2) The inner mold needs to be transferred between the mold opening station and the mold closing station. Therefore, in order to ensure coordinated action, the movement trajectories of the two sets of clamping mechanisms must be different. The clamping mechanism needs to drive the inner mold to move to the side to complete the station transfer. Because the inner mold needs to be taken out and cleaned after it is taken out, the inner mold transferred to the side further facilitates the removal and cleaning operations, fully realizing the adaptation between the structural layout and the process execution.

[0041] (3) The clamping, opening, closing and cleaning of the inner mold must be based on the precise positioning of the mold. Therefore, a pair of limiters and a mold positioning unit are set at the front end of the mold opening machine. When the mold is positioned by a pair of limiters and placed on the turntable by a pair of clamps B, the axial positioning can be guaranteed; then based on the fixed axis rotation of the turntable, the positioning of the mold line can be met; during the latter adjustment process, the mold will not have an axial deviation. Compared with the traditional clamping rotation, the positioning accuracy is higher and the positioning convenience is better.

[0042] (4) The rotational positioning of the mold is achieved through a sensor that uses a laser rangefinder to achieve pre-positioning by identifying the first through hole. However, since there may be defects on the side of the first through hole or other defects on the bottom of the mold, there may be errors in the positioning. Therefore, the lifting member is inserted into the second through hole by lifting and lowering, and precise positioning is achieved based on the cooperation between the lifting member and the second through hole.

[0072] The following combines specific embodiments to further elaborate on the content of the present invention:

[0073] As Figure 1 shown, a blank taking mechanism based on a ceramic multi - petal mold includes a mold linear handling unit 1, a mold positioning unit 4, an inner and outer mold disassembly and assembly unit, and a mold opening and blank placing unit.

[0074] As Figure 2 shown, the mold linear handling unit 1 includes a carrier table 11 and a moving module 12.

[0075] As Figure 3 shown, the carrier table 11 is provided with a hole searching station 111, a mold opening station 112, a reserved station 113, and a mold clamping station 114 arranged in sequence along a preset first direction; As Figure 2 , Figure 4As shown, a mold positioning unit 4 is provided at the hole-finding station 111 corresponding to the carrier table 11, positioning seats 115 are provided at the mold-opening station 112 and the reserved station 113 corresponding thereto, and a belt conveyor line A116 is provided at the mold-closing station 114 corresponding thereto; the upper end surfaces of the mold positioning unit 4, the positioning seats 115, and the belt conveyor line A116 are at the same height, and this height is set as H.

[0076] The moving module 12 is provided corresponding to three adjacent stations and alternately transfers between the first three stations and the last three stations. Combining Figure 4 As shown, the moving module 12 includes three support seats 121 of the same height. The support seats 121 are composed of four square plates, and a "cross"-shaped space is formed in the middle for accommodating the corresponding mold positioning unit 4, positioning seats 115, and belt conveyor line A116; the support seats 121 are configured to move along the first direction and the vertical direction and are driven by cylinders; when the support seats 121 move upward to the extreme position, the height of their upper end surfaces is higher than H, and when the support seats 121 move downward to the extreme position, the height of their upper end surfaces is lower than H; the three support seats 121 are sequentially arranged corresponding to the hole-finding station 111, the mold-opening station 112, and the reserved station 113, or are sequentially arranged corresponding to the mold-opening station 112, the reserved station 113, and the mold-closing station 114; each action of the moving module 12 includes rising, translating, and descending, thereby realizing the synchronous movement of the molds at the first three stations by one station to the last three stations; after the movement is completed, the moving module 12 immediately resets horizontally to the first three stations and continues to perform the actions of rising, translating, and descending, and so on.

[0077] In this embodiment, as Figure 1 shown, a feeding table 2 is provided at the front end of the carrier table 11, and a discharging table 3 is provided at the end of the carrier table 11.

[0078] A handling mechanism is provided above the feeding table 2 and the hole-finding station 111 for handling the mold from the feeding table 2 to the rotating mechanism 41; as Figure 5 shown, the handling mechanism includes a pair of clamping jaws B21 distributed perpendicular to the first direction, a cylinder for driving the pair of clamping jaws B21 to move relatively, and a combination of a motor, a transmission wheel, and a conveyor belt for driving the pair of clamping jaws B21 to move synchronously along the first direction; a pair of limit members 22 are provided on one side of the feeding table 2 biased towards the carrier table 11, and the pair of limit members 22 can move relatively perpendicular to the first direction and are driven by a cylinder. When the pair of limit members 22 approach each other, they are used to abut against the outer wall of the mold to realize the positioning of the mold, and the mold is transferred to the rotating mechanism 41 by the clamping of the pair of clamping jaws B21, ensuring the position accuracy of the axis of the mold placed on the rotating mechanism 41; when the pair of limit members 22 move away from each other, an avoidance space is formed in the middle for the mold to pass through and reach the hole-finding station 111 from the feeding table 2.

[0079] The discharging table 3 includes a belt conveyor line B31, and the upper surface height of the belt conveyor line B31 is equal to that of the belt conveyor line A116, so that the mold at the mold closing station 114 can be moved out along the belt conveyor line A116 and the belt conveyor line B31.

[0080] The mold positioning unit 4 is correspondingly arranged at the hole searching station 111 and includes a rotating mechanism 41, a sensor (not shown in the figure), and a jacking member 42.

[0081] As Figure 6 shown, the rotating mechanism 41 is used to carry the mold and includes a rotating table 411 and a rotating motor 412 for driving the rotating table 411 to rotate; the mold 01 includes an inner mold 012 and an outer mold 011. As Figure 3 shown, the lower end of the outer mold 011 has a first through hole 013 for positioning and a second through hole 014 for precise positioning; the inner mold 012 adopts two-piece molds and has a mold closing line 015, and the height of the inner mold 012 is higher than that of the outer mold 011; the mold is placed on the rotating table 411, and the first through hole 013 and the second through hole 014 are located at positions where the lower end face of the outer mold 011 is exposed outside the end face of the rotating table 411, and two second through holes 014 are arranged radially on the lower end face of the mold 01; the sensor adopts a laser distance measuring sensor and is arranged directly below any position point on the rotation path of the first through hole 013 along with the rotating table 411 to identify the first through hole 013 during the rotation of the mold and achieve hole searching alignment; the jacking member 42 is arranged directly below any position point on the rotation path of the second through hole 014 along with the rotating table 411; when the sensor is aligned with the first through hole 013, the jacking member 42 is aligned with the second through hole 014. However, due to possible defects on the side of the first through hole 013 or other defects at the bottom of the mold, the sensor may misidentify and cause positioning errors. Therefore, the jacking member 42 is provided to achieve precise positioning by inserting the jacking member 42 into the second through hole 014, which is convenient for subsequent mold opening and blank taking. As Figure 3 shown, after the mold is positioned, the mold closing line 015 is parallel or perpendicular to the first direction. In this embodiment, it is set that the mold closing line 015 is parallel to the first direction.

[0082] As Figure 1 、 Figure 2 shown, the inner and outer mold disassembly and assembly unit includes an outer mold pressing mechanism 5 and an inner mold grasping mechanism 6.

[0083] As Figure 2As shown in the figure, the outer mold clamping mechanism 5 is correspondingly arranged on both sides of the mold opening station 112 and is distributed perpendicular to the first direction. In this embodiment, the outer mold clamping mechanism 5 uses an elbow clamp driven by a cylinder to act on the edge of the upper end face of the outer mold 011 to realize the clamping of the outer mold 011, which is convenient for the subsequent removal of the inner mold 012. Of course, to ensure the accuracy of the elbow clamp action, a pair of positioning jaws 51 are also arranged on both sides of the mold opening station 112, distributed perpendicular to the first direction, driven by a cylinder and abutted against the outer wall of the outer mold 011 to prevent misalignment of the axis of the outer mold 011 and facilitate the outer mold clamping mechanism 5 to perform the clamping action.

[0084] As Figure 1 shown, two inner mold grasping mechanisms 6 are provided in total and are correspondingly arranged above the mold opening station 112 and the mold closing station 114. As Figure 7 、 9 shown, the inner mold grasping mechanism 6 has a pair of jaws A61, and the distribution direction of the pair of jaws A61 is parallel to the mold closing line 015. The pair of jaws A61 realize relative movement in the first direction and synchronous movement in the vertical direction, and are respectively driven by cylinders. During operation, the pair of jaws A61 are used to clamp the outer wall of the structure where the inner mold 012 protrudes from the outer mold 011. Each jaw A61 has two clamping points, and during the clamping process, it abuts against the outer walls of the two halves of the mold on both sides of the mold closing line 015 respectively.

[0085] Combined with Figure 10 shown, there are two groups of mold opening and blank placing units, including a clamping mechanism 7, a moving mechanism and a blank clamping and picking mechanism 9.

[0086] As Figure 11 、 Figure 12 shown, the clamping mechanism 7 clamps each half of the inner mold 012 to complete the opening and closing action. The clamping mechanism 7 has a pair of supporting claws 71, and the distribution direction of the pair of supporting claws 71 is perpendicular to the mold closing line 015. When clamping, each supporting claw 71 clamps the corresponding half of the mold respectively. In this embodiment, for the two-half mold structure of the inner mold 012, the distribution direction of the pair of jaws A61 is perpendicular to the distribution direction of the pair of supporting claws 71, which effectively ensures the subsequent mold opening operation. Combined with Figure 8 shown, a receiving space is formed between the pair of supporting claws 71 for the pair of jaws A61 to penetrate, realizing the transfer of the inner mold 012 between the pair of jaws A61 and the pair of supporting claws 71 during the installation and disassembly process. Above the mold opening station 112, the pair of jaws A61 clamp the inner mold 012 and transfer it between the pair of supporting claws 71. Above the mold closing station 114, the pair of supporting claws 71 clamp the inner mold 012 and transfer it between the pair of jaws A61. In this embodiment, the relative movement of the pair of supporting claws 71 in the direction perpendicular to the first direction is driven by a cylinder.

[0087] A pair of supporting claws 71 move synchronously along a direction perpendicular to the first direction and along the first direction, and are driven by a moving mechanism, so as to drive the clamping mechanism 7 to move along a U-shaped trajectory, and the clamping mechanism 7 drives the inner mold 012 to transfer between above the mold opening station 112 and above the mold clamping station 114, specifically as Figure 10 shown; in this embodiment, the synchronous movement of a pair of supporting claws 71 along a direction perpendicular to the first direction is driven by a cylinder, and the synchronous movement along the first direction is driven by a cylinder, or a combination of a servo motor and a lead screw, or a combination of a motor, a transmission wheel and a conveyor belt.

[0088] As Figure 10 shown, the movement trajectories 8 of a pair of clamping mechanisms 7 are symmetrically arranged, and the two movement trajectories 8 respectively correspond to the thin solid line part (X1) and the thick solid line part (X2) in the figure; each movement trajectory 8 includes a first path 81, a second path 82 and a third path 83; the first path 81 and the third path 83 are perpendicular to the first direction, and the second path 82 is parallel to the first direction; a pair of clamping mechanisms 7 always move in opposite directions synchronously on the corresponding second path 82. The first path 81 is on the side of the mold opening station 112, and the third path 83 is on the side of the mold clamping station 114; as Figure 13 shown, there is a blank taking station at the intersection of the first path 81 and the second path 82, that is, the positions corresponding to A1 and A2; there is a waiting station at the intersection of the second path 82 and the third path 83, that is, the positions corresponding to B1 and B2; the starting end of the first path 81 is above the mold opening station 112, that is, at the C1 position; the end of the second path 82 is above the mold clamping station 114, that is, at the C2 position; when any clamping mechanism 7 is at the waiting station, the other clamping mechanism 7 shuttles between above the mold opening station 112 and the blank taking station; when any clamping mechanism 7 is at the blank taking station, the other clamping mechanism 7 shuttles between above the mold clamping station 114 and the waiting station.

[0089] Furthermore, during the process of the clamping mechanism 7 transferring from the mold opening station 112 to the mold clamping station 114, it stops at the blank taking station and the waiting station in sequence; when the clamping mechanism 7 stops at the blank taking station, the lower moving module 12 moves one station, and when the clamping mechanism 7 stops at the waiting station, the lower moving module 12 moves one more station. Thus, after the inner mold 012 is taken out, it can be smoothly placed into the corresponding outer mold 011 after moving two stations; during the process of the clamping mechanism 7 transferring from the mold clamping station 114 to the mold opening station 112, it does not stop and moves along the third path 83, the second path 82 and the first path 81 in sequence.

[0090] Set two groups of clamping mechanisms 7 as the first clamping mechanism and the second clamping mechanism. The first clamping mechanism moves along the movement trajectory X1, and the second clamping mechanism moves along the movement trajectory X2. The specific principle of their coordinated actions is as follows:

[0091] (1) When the first clamping mechanism moves back along the second path 82 of the movement trajectory X1 to A1, the second clamping mechanism moves along the second path 82 of the movement trajectory X2 to B2. The above two actions are executed synchronously, and the first clamping mechanism is unloaded while the second clamping mechanism is fully loaded. At this time, the first clamping mechanism directly moves to C1, and the second clamping mechanism waits at B2.

[0092] (2) After the first clamping mechanism picks up the inner mold 012 at C1 and then moves to A1, the second clamping mechanism continues to wait at B2 during this process. Wait for the moving module 12 to synchronously transfer the molds on the hole-finding station 111, mold-opening station 112, and reserved station 113 to the mold-opening station 112, reserved station 113, and mold-closing station 114.

[0093] (3) When the first clamping mechanism holds the inner mold 012 and stays at A1, the inner mold 012 performs the operations of blank taking and cleaning. At this time, the second clamping mechanism shuttles between B2 and C2, places the held inner mold 012 in the outer mold 011 at C2. Then the first clamping mechanism is at A1 and the second clamping mechanism is at B2, and the first clamping mechanism is fully loaded while the second clamping mechanism is unloaded.

[0094] (4) The first clamping mechanism moves along the second path 82 of the movement trajectory X1 to B1, and the second clamping mechanism moves along the second path 82 of the movement trajectory X2 to A2. The above two actions are executed synchronously. At this time, the first clamping mechanism waits at B1, and the second clamping mechanism directly moves to C1, picks up the inner mold 012 and then returns to A2. Thus, when the first clamping mechanism waits at B1, the second clamping mechanism shuttles between A2 and C1. This cycle repeats.

[0095] It should also be noted that in this embodiment, an outer mold cleaning mechanism can be set at the reserved station 113. After the inner mold 012 is taken out and the outer mold 011 moves to the reserved station 113, it can be cleaned by the outer mold cleaning mechanism, which is convenient for the subsequent placement of the inner mold 012. Furthermore, the setting of the reserved station 113 can, on the premise of meeting the setting of the outer mold cleaning mechanism, achieve the coordination of the above two groups of clamping mechanisms 7 during the movement process, ensure that the efficiency reaches the optimum, and reduce the average working time of a single-piece ceramic mold to about 10 s.

[0096] As Figure 14 shown, the blank clamping mechanism 9 is used to take out the blank from the inner mold 012. At this time, the inner mold 012 is at the blank-taking station and is separated by a pair of supporting claws 71. The blank clamping mechanism 9 includes a clamping head 91 and a robotic arm 92 that drives the clamping head 91 to move. The clamping head 91 tightly holds the blank from the inside, and then takes out and transfers the blank.

[0097] After the blank is taken out from the inner mold 012, the joint line 015 of each split mold needs to be cleaned. Therefore, in this embodiment, an inner mold cleaning mechanism 10 is provided below the blank taking station, as Figure 15 shown. The inner mold cleaning mechanism 10 has a brush 101 that rotates axially. The axial direction of the brush 101 is parallel to the joint line 015 and is lifted and lowered by the drive of a cylinder. After the blank is taken out, the brush 101 rises between a pair of opened split molds, and the joint line 015 is cleaned by the rotation of the brush 101.

[0098] Based on the movement process of a single mold, its working principle is as follows:

[0099] (1) The mold is placed on the feeding table 2 and limited by a pair of limiters 22; after the limiting is completed, the mold is clamped by a pair of clamping jaws B21 and transferred to the hole searching station 111; during the transfer process, the pair of limiters 22 move away from each other to form an avoidance space for the mold to pass through;

[0100] (2) When the mold reaches the hole searching station 111, it is placed on the rotating table 411 and rotates driven by the rotating motor 412. During the process, the first through hole 013 is identified by the sensor. When the sensor is aligned with the first through hole 013, the lifting member 42 is aligned with the second through hole 014; however, due to the error in sensor identification, the lifting member 42 moves upward and is inserted into the second through hole 014 to achieve precise positioning of the mold; after the positioning is completed, the mold is transferred to the mold opening station 112 by the moving module 12;

[0101] (3) When the mold reaches the mold opening station 112, it is positioned by a pair of positioning clamping jaws 51, and the upper end surface of the outer mold 011 is pressed by a pair of outer mold pressing mechanisms 5; then, a pair of clamping jaws A61 of the inner mold grasping mechanism 6 grasp the inner mold 012 and transfer it to the clamping mechanism 7; a pair of supporting claws 71 of the clamping mechanism 7 drive the inner mold 012 to move to the blank taking station and perform mold opening, blank taking, and cleaning operations;

[0102] (4) When the clamping mechanism 7 is at the blank taking station, the moving module 12 drives the mold to move one station from the mold opening station 112 to the reserved station 113; when the mold opening, blank taking, and cleaning are completed and the clamping mechanism 7 is at the waiting station, the moving module 12 moves one station again from the reserved station 113 to the mold closing station 114; at this time, the clamping mechanism 7 transfers the inner mold 012 to between a pair of clamping jaws A61 above the mold closing station 114 and places it into the outer mold 011. Thus, the mold opening, blank taking, cleaning, and mold closing operations of one mold are completed.
