[0018] Furthermore, both the No. 1 connecting rod 3 and the No. 2 connecting block 4 adopt a cylindrical rod structure, and the No. 1 connecting rod 3 and the No. 2 connecting block 4 have the same length.

[0019] In the present technical solution, the No. 1 connecting block 1, the No. 1 connecting rod 3, the No. 2 connecting block 4, the No. 2 connecting rod 6, the No. 3 connecting block 7 and the material picking claw 9 are connected to the robot arm through a robot arm connecting unit, the robot arm claw is controlled by the injection molding equipment program, and the material picking claw 9 is controlled by the M6 ​​pneumatic device.

In addition, while improving production efficiency, it frees up the limitations of manual labor and does not require dedicated personnel to perform the operation, thus avoiding employee safety risks and saving production time.

[0020] According to the preferred embodiment, the robot arm connection unit includes:

[0021] A quick-change connector 10, wherein the quick-change connector 10 comprises an integrally arranged flange mounting block 1001 and a bottom connecting block 1002, wherein the flange mounting block 1001 is connected to the robot arm, and the bottom connecting block 1002 is arranged on a side of the flange mounting block 1001 away from the robot arm;

[0022] The connecting plate 11 passes through a side of the connecting plate 11 away from the robot arm through a robot arm connecting bolt 12 and extends into the quick-change connecting piece 10 to be fastened to the quick-change connecting piece 10 .

[0023] Furthermore, the quick-change connector 10 and the connecting plate 11 are coaxially arranged.

[0024] Furthermore, the outer diameter of the flange mounting block 1001 is greater than the outer diameter of the bottom connecting block 1002 , the outer diameter of the bottom connecting block 1002 is greater than the outer diameter of the connecting plate 11 , and the height of the bottom connecting block 1002 is greater than the heights of the flange mounting block 1001 and the connecting plate 11 .

[0025] In the present technical solution, the robot arm connection unit serves as the connection basis between the No. 1 connection block 1, the No. 1 connection rod 3, the No. 2 connection block 4, the No. 2 connection rod 6, the No. 3 connection block 7 and the material picking clamp 9 and the robot arm, and its structural stability needs to be ensured. Therefore, a connection structure of a quick-change connector 10 and a connecting plate 11 is adopted. In this structure, since the structural dimensions on both sides of the robot arm connection unit are quite different, the outer diameter of the flange mounting block 1001 is larger than the outer diameter of the bottom connecting block 1002, and the outer diameter of the bottom connecting block 1002 is larger than the outer diameter of the connecting plate 11 for transition. The larger flange mounting block 1001 can ensure sufficient contact area with the robot arm, and thus can achieve sufficient connection strength.

[0026] According to a preferred embodiment, the connection plate 11 is connected to the quick-change connector 10 by means of multiple groups of robot arm connection bolts 12 .

[0027] Furthermore, four groups of robot arm connecting bolts 12 are arranged at equal intervals around the connecting plate 11 .

[0028] In the present technical solution, since the height of the bottom connecting block 1002 mentioned above is greater than the height of the flange mounting block 1001 and the connecting plate 11, sufficient connection space can be provided for the robot arm connecting bolts 12. At the same time, the connecting plate 11 is connected to the quick-change connector 10 through four groups of robot arm connecting bolts 12. The above structure can ensure the connection stability of the internal structure of the robot arm connecting unit, and provide sufficient stability for the connection between the lower No. 2 connecting rod 6 and the material picking clamp 9, even during the movement of the material picking clamp 9, to avoid the robot arm connecting unit from being separated from the lower structure.

[0029] According to the preferred embodiment, the first connection block 1 is arranged in a T-shape, including a first connection block horizontal end 101 and a first connection block vertical end 102;

[0030] The horizontal end 101 of the No. 1 connection block extends toward both ends of the vertical end 102 of the No. 1 connection block to form a No. 1 connection block mounting end 103, and the No. 1 connection block connecting bolt 104 passes through the side of the No. 1 connection block mounting end 103 away from the robot arm and extends into the robot arm connecting unit to be fastened to the connecting plate 11;

[0031] A No. 1 connection hole 2 parallel to the robot arm connection unit is formed on the No. 1 connection block vertical end 102, and a No. 1 connection rod 3 passes through the No. 1 connection hole 2;

[0032] A connecting rod fastening unit is also provided on the vertical end 102 of the No. 1 connecting block between the No. 1 connecting hole 2 and the horizontal end 101 of the No. 1 connecting block. The connecting rod fastening unit is vertical and abuts against the No. 1 connecting rod 3 .

[0033] Furthermore, the horizontal end 101 of the first connecting block and the vertical end 102 of the first connecting block are coaxially arranged.

[0034] In the present technical solution, the No. 1 connecting block 1 needs to be used to realize the fastening and installation of the No. 1 connecting rod 3, and the No. 1 connecting block 1 also needs to be used to connect the No. 1 connecting rod 3 to the robot arm connection unit. Therefore, on the one hand, the No. 1 connecting block 1 is set to a T-shaped structure, and the No. 1 connecting block connecting bolt 104 is passed through the No. 1 connecting block horizontal end 101 to realize the connection with the upper structure, and the No. 1 connecting block horizontal end 101 is arranged on both sides, which can be conducive to achieving the stability and balance of the connection;

[0035] On the other hand, in actual use, it is necessary to take into account that the No. 1 connecting rod 3 is a cylindrical structure, and it is also necessary to adjust the installation length of the No. 1 connecting rod 3. Therefore, on the basis of realizing the fastening and installation of the cylindrical No. 1 connecting rod 3 through the connecting rod fastening unit, the No. 1 connecting rod 3 whose installation position can be adjusted front and back can be locked at any length through the connecting rod fastening unit vertically and against the No. 1 connecting rod 3.

[0036] According to a preferred embodiment, the connecting rod fastening unit comprises:

[0037] A fastening hole 13, wherein the fastening hole 13 and the corresponding connecting hole are arranged perpendicular to each other and cross and overlap each other, and the side surface of the connecting rod passing through the corresponding connecting hole is located in the fastening hole 13;

[0038] A fastening bolt 14, wherein the fastening bolt 14 is installed in the fastening hole 13;

[0039] A fastening nut 15, which is sleeved on one end of the fastening hole 13 away from the bolt head of the fastening bolt 14, and the fastening nut 15 is connected to the fastening bolt 14 by a thread, and a profile structure 16 is provided on the top side of the fastening nut 15 close to the bolt head of the fastening bolt 14, and the profile structure 16 is abutted against the side of the corresponding connecting rod;

[0040] The installation position of the fastening nut 15 is adjusted by the fastening bolt 14 to adjust the connection locking degree of the corresponding connecting rod.

[0041] Furthermore, the length of the fastening bolt 14 does not exceed the length of the fastening hole 13 .

[0042] In the present technical solution, the locking of the No. 1 connecting rod 3 is taken as an example. The connecting rod fastening unit can realize the fastening and locking of the No. 1 connecting rod 3. Therefore, in this structure, the fastening hole 13 in the connecting rod fastening unit can pass through the No. 1 connecting rod 3, and the fastening nut 15 for locking the No. 1 connecting rod 3 is provided with a profiling structure, which can effectively resist and adhere to the arc surface of the No. 1 connecting rod 3 when locking.

[0043] When in use, the driving member used in the connecting rod fastening unit is a fastening bolt 14 that can pass through the fastening hole 13 and the fastening nut 15. Matching threads are provided on the inner and outer surfaces of the fastening bolt 14 and the fastening nut 15. By tightening, the installation is convenient, the adjustment time is saved, the installation efficiency is improved, and the training requirements for operators are reduced.

[0044] According to a preferred embodiment, the fastening hole 13 is provided with a bolt head mounting hole 131 and a bolt rod mounting hole 132 in sequence along the axial direction, and the inner diameter of the bolt head mounting hole 131 is larger than the inner diameter of the bolt rod mounting hole 132;

[0045] A fastening nut mounting hole 133 is coaxially arranged on one side of the bolt rod mounting hole 132 away from the bolt head mounting hole 131, and the top of the fastening nut mounting hole 133 does not exceed the center height of the No. 1 connecting hole 2;

[0046] The top side of the fastening nut installation hole 133 is overlapped with the No. 1 connecting hole 2.

[0047] Furthermore, the height of the bolt head mounting hole 131 is not less than the height of the bolt head of the fastening bolt 14 .

[0048] In the present technical solution, in order to adapt to the purpose of locking the No. 1 connecting rod 3 with an adjusted installation position by the connecting rod fastening unit, and to achieve the effect of circumferentially abutting the side surface of the No. 1 connecting rod 3 to prevent rotation after locking, the fastening hole 13 is arranged to correspond to the fastening bolt 14, the fastening nut 15 and the No. 1 connecting rod 3, and the bolt head mounting hole 131 and the bolt rod mounting hole 132 are sequentially opened along the axial direction, and a fastening nut mounting hole 133 is coaxially opened on the outer side of the bolt rod mounting hole 132;

[0049] The fastening nut mounting hole 133 not only matches the fastening nut 15, but also needs to correspond to the arc-shaped outer side structure of the No. 1 connecting rod 3. Therefore, the top side of the fastening nut mounting hole 133 is overlapped with the No. 1 connecting hole 2. In addition, in order to avoid damage to the No. 1 connecting rod 3 after the fastening nut 15 is excessively installed and locked upward after rotating along the fastening bolt 14, the top of the fastening nut mounting hole 133 is set not to exceed the center height of the No. 1 connecting hole 2. In addition, since the outer diameter of the fastening nut mounting hole 133 is always larger than the bolt rod mounting hole 132, the bolt rod mounting hole 132 can also play an effective limiting role.

[0050] According to the preferred embodiment, a No. 2 connecting hole 17 and a No. 3 connecting hole 5 which are perpendicular to each other are provided in the No. 2 connecting block 4, and a pair of mutually perpendicular connecting rod fastening units are provided between the No. 2 connecting hole 17 and the No. 3 connecting hole 5, and the pair of connecting rod fastening units are respectively perpendicularly arranged with the adjacent No. 2 connecting hole 17 and No. 3 connecting hole 5.

[0051] Furthermore, the No. 2 connection hole 17 and its corresponding connection rod fastening unit, the No. 3 connection hole 5 and its corresponding connection rod fastening unit are respectively symmetrically arranged at the center of the No. 2 connection block 4 .

[0052] In the present technical solution, the other end of the No. 1 connecting rod 3 and the No. 2 connecting rod 6 are respectively installed on the No. 2 connecting block 4. Under the action of the No. 2 connecting block 4, it is necessary to ensure the locking effect of the No. 1 connecting rod 3 and the No. 2 connecting rod 6, and to achieve the purpose of adjusting the installation position, length and angle of the No. 1 connecting rod 3 and the No. 2 connecting rod 6. At the same time, considering avoiding cumbersome structure and increasing the difficulty of operator training, it is preferred that each No. 2 connecting hole 17 and No. 3 connecting hole 5 still adopts the same connecting rod fastening unit structure as the No. 1 connecting hole 2;

[0053] Since two sets of structure fixation need to be set on the same No. 2 connecting block 4, the structure distribution on the same No. 2 connecting block 4 must also meet the position requirements of the No. 1 connecting rod 3 and the No. 2 connecting rod 6. In addition, it is also necessary to consider that the strength of the overall structure will not be destroyed. Therefore, a pair of mutually perpendicular connecting rod fastening units are arranged between the No. 2 connecting hole 17 and the No. 3 connecting hole 5. At the same time, the No. 2 connecting hole 17 and its corresponding connecting rod fastening unit, the No. 3 connecting hole 5 and its corresponding connecting rod fastening unit also adopt a structure symmetrically arranged with respect to the center of the No. 2 connecting block 4, so that the structure of the No. 2 connecting block 4 is more compact and efficient.

[0054] According to a preferred embodiment, both ends of the second connecting block 4 are arranged to be arc-shaped structures 41 , and the arc-shaped structures 41 on both sides are arranged perpendicular to each other.

[0055] Furthermore, the center of the arc structure 41 on each side and the center of the correspondingly installed connecting rod are located on the same vertical center line.

[0056] In the technical solution, the second connecting block 4 acts as a connecting hub between the first connecting rod 3 and the second connecting rod 6, adjusting the horizontal direction to the vertical direction, so that the material removal clamp 9 installed at the bottom of the second connecting rod 6 can adjust its position in a direction suitable for the purpose of quickly removing the waste from the injection mold;

[0057] Since the directions of the forces acting on the No. 1 connecting rod 3 and the No. 2 connecting rod 6 are different and they are in a vertical structure, the arc structures 41 on both sides of the No. 2 connecting block 4 are arranged vertically to each other, which can more effectively resist the torque, improve the overall stability of the No. 2 connecting block 4 and the No. 1 connecting rod 3 and the No. 2 connecting rod 6, and enable the No. 2 connecting block 4 to disperse and transfer the load more evenly when subjected to external force, thereby avoiding stress concentration and damage;

[0058] Furthermore, the arrangement of the arc structure 41 is coaxial with the corresponding connecting rod, which can ensure that the force of the connecting rod is evenly distributed on the second connecting block 4, reduce stress concentration and reduce local pressure on the structure, avoid twisting and deformation, and help enhance the overall stability and durability of the structure of the second connecting block 4.

[0059] According to the preferred solution, the third connection block 7 comprises:

[0060] A connecting rod connecting end 71, wherein a fourth connecting hole 72 is formed on the connecting rod connecting end 71 and passes through the second connecting rod 6;

[0061] A material taking clamping claw connection end 73, wherein the material taking clamping claw connection end 73 is integrally arranged on a side surface of the connecting rod connection end 71, and the material taking clamping claw connection end 73 is arranged parallel to the fourth connecting hole 72;

[0062] A vertical mounting plane 8, on the side of the material taking clamping claw connection end 73 away from the connecting rod connection end 71, a vertical mounting plane 8 for mounting the material taking clamping claw 9 is formed;

[0063] A connecting rod fastening unit is also provided between the connecting rod connecting end 71 and the material taking clamping claw connecting end 73 , and the second connecting rod 6 is locked and installed on the connecting rod connecting end 71 through the connecting rod fastening unit.

[0064] Furthermore, the connecting rod connection end 71 and the material taking clamp connection end 73 are arranged in a T-shaped structure.

[0065] In the present technical solution, the No. 3 connecting block 7 is required to achieve the purpose of connecting the No. 2 connecting rod 6 and the material taking clamp 9. The installation direction of the material taking clamp 9 needs to be adjusted in angle and height according to the injection mold gate position. Therefore, the structure of the connecting rod fastening unit can still be used in the No. 3 connecting block 7 to achieve locking;

[0066] When in use, the installation height of the No. 3 connecting block 7 on the No. 2 connecting rod 6 can be adjusted by adjusting the installation height, thereby achieving the purpose of adjusting the installation height of the material picking clamp 9. The installation angle of the No. 3 connecting block 7 can be adjusted by rotating the angle of the No. 3 connecting block 7 on the No. 2 connecting rod 6, thereby achieving the purpose of adjusting the installation angle of the material picking clamp 9.

[0067] According to the preferred solution, the material taking clamping jaw 9 is installed on the third connecting block 7 through the clamping jaw connecting bolt 18.

[0068] Furthermore, the width of the material taking clamping claw connection end 73 is greater than the width of the connecting rod connection end 71 , and the width of the material taking clamping claw connection end 73 is greater than the width of the material taking clamping claw 9 .

[0069] In the present technical solution, since the material taking clamp 9 can be controlled by a pneumatic device, the simpler the installation method of the material taking clamp 9 is, the better, which can avoid increasing the difficulty of operator training and reduce the impact on the working of the material taking clamp 9. Therefore, it is preferred to set the width of the material taking clamp connection end 73 to be greater than the width of the connecting rod connection end 71, and the extra position of the material taking clamp connection end 73 compared with the connecting rod connection end 71 provides an installation position for the clamp connection bolt 18;

[0070] At the same time, the width of the material picking jaw connecting end 73 is greater than the width of the material picking jaw 9. On the one hand, the wider material picking jaw connecting end 73 can better adapt to material picking jaws 9 of different sizes and types, improve the versatility and flexibility of the material picking jaw 9, and reduce the cost and time of replacing the jaws; on the other hand, the wider material picking jaw connecting end 73 can increase the contact area when connecting with the material picking jaw 9, thereby providing a more stable connection, which helps to prevent the material picking jaw 9 from falling off or loosening due to vibration or impact during operation, thereby ensuring the accuracy and stability of material picking.

[0071] The utility model realizes rapid docking on the mechanical arm through the mechanical arm connection unit, realizes adjustment of the installation height and angle of the material picking claw through multiple connecting rods and multiple connecting blocks, flexibly adapts to the material picking needs of different injection molds, and the injection molding equipment outputs an air source, and the claw performs the material picking action to realize the automatic operation of the equipment, replacing the operator's manual removal, while avoiding the safety risk of employees, saving time, and improving production efficiency.

[0104] The utility model proposes a mechanical claw device for taking materials from the runner of an injection mold, which is used in the injection mold taking material process. The utility model does not limit the type of injection mold, but the structure of the mechanical claw device for taking materials from the runner of an injection mold is particularly suitable for the need to take waste materials from the runner riser of an injection mold.

[0105] In general, the mechanical claw device for taking out materials from the injection mold runner proposed in the utility model mainly includes a mechanical arm connection unit, a No. 1 connection block 1, a No. 1 connection rod 3, a No. 2 connection block 4, a No. 2 connection rod 6, a No. 3 connection block 7 and a material taking claw 9. Among them, you can refer to Figure 1, which shows the arrangement relationship of the robot arm connection unit, the No. 1 connection block 1, the No. 1 connection rod 3, the No. 2 connection block 4, the No. 2 connection rod 6, the No. 3 connection block 7 and the material picking clamp 9.

[0106] In order to realize the automatic removal of required items during production of injection molding equipment, thereby replacing the purpose of manual labor, the problem in the background technology is that after the injection mold is completed, there is still waste stuck to the gate of the mold, which needs to be cleaned. However, due to the safety considerations of the equipment, the mold that has just finished injection molding is usually cleaned manually, and the safety door needs to be stopped and opened each time. In the long run, it is not suitable for long-term use of automated equipment. In addition, due to space limitations, it is very inconvenient to manually remove waste, and because the equipment and safety door must be opened each time for manual removal, the production rhythm is disrupted and manpower is occupied. Moreover, there may be errors in manual operation, resulting in different ways and effects of waste treatment each time. Inconsistency affects the consistency of the product and has extremely low production efficiency. At the same time, the operating workers need to directly contact the high-temperature molds and sharp edges, which may lead to safety risks such as burns and scratches, and there are certain safety hazards. For this reason, in the technical solution provided in this embodiment, the mechanical arm is connected by a mechanical arm connection unit to achieve quick docking, and the installation height and angle of the material picking claw are adjusted by multiple connecting rods and multiple connecting blocks to flexibly adapt to the material picking needs of different injection molds. The injection molding equipment outputs an air source, and the claw performs the material picking action to realize the automatic operation of the equipment, instead of the operator manually taking out the material, while avoiding the safety risk of employees, saving time and improving production efficiency.

[0107] On the whole, if Figure 1 As shown, from top to bottom, a mounting plane of the lower structure is provided at the bottom of the robot arm through the robot arm connecting unit, and a No. 1 connecting block 1 is installed on the bottom mounting plane of the robot arm connecting unit, and then a No. 1 connecting hole 2 parallel to the robot arm connecting unit is opened on the No. 1 connecting block 1, and one end of the No. 1 connecting rod 3 is installed through the No. 1 connecting hole 2. At this time, the No. 1 connecting rod 3 is arranged parallel to the robot arm connecting unit, and a No. 2 connecting block 4 is installed on the other end of the No. 1 connecting rod 3. At the same time, a No. 2 connecting block 4 is also opened perpendicular to The No. 3 connecting hole 5 of the No. 1 connecting rod 3, one end of the No. 2 connecting rod 6 is installed through the No. 3 connecting hole 5, at this time, the No. 2 connecting rod 6 and the No. 1 connecting rod 3 are vertically arranged to realize the conversion of the connecting rod from the horizontal position to the vertical position; finally, the No. 3 connecting block 7 is installed on the other end of the No. 2 connecting rod 6, and the No. 3 connecting block 7 pre-provides a vertical mounting plane 8 for the material picking clamp 9 for installation, and the clamp air pipe structure 19 of the material picking clamp 9 for clamping the waste material out of the injection mold gate is connected to the M6 ​​pneumatic device to control the opening and closing of the material picking clamp 9.

[0108] When in use, the No. 1 connecting block 1, No. 1 connecting rod 3, No. 2 connecting block 4, No. 2 connecting rod 6, No. 3 connecting block 7 and the material picking claw 9 are connected to the robot arm through the robot arm connection unit, the robot arm claw is controlled by the injection molding equipment program, and the material picking claw 9 is controlled by the M6 ​​pneumatic device. By adjusting the installation length of the No. 1 connecting rod 3 and the No. 2 connecting rod 6, and the installation angle of the No. 2 connecting block 4 and the No. 3 connecting block 7, the effect of obtaining a suitable installation position can be achieved, which is suitable for the removal of waste materials from different mold gates. Therefore, when the injection molding equipment is in production and the required items need to be taken out, the material picking claw can be used instead of manual labor, thereby realizing an automated production process and avoiding product quality problems caused by its shutdown. In addition, while improving production efficiency, it frees up the limitations of manual labor and does not require dedicated personnel to perform the operation, thus avoiding safety risks for employees and saving production time.

[0109] like Figure 2 As shown, the robot arm connection unit serves as the connection basis between the No. 1 connection block 1, the No. 1 connection rod 3, the No. 2 connection block 4, the No. 2 connection rod 6, the No. 3 connection block 7 and the material picking clamp 9 and the robot arm, and its structural stability needs to be ensured. Therefore, a connection structure of a quick-change connector 10 and a connecting plate 11 is adopted, wherein the quick-change connector 10 includes an integrally arranged flange mounting block 1001 and a bottom connecting block 1002, the flange mounting block 1001 is connected to the robot arm, and the bottom connecting block 1002 is arranged on the side of the flange mounting block 1001 away from the robot arm, and correspondingly, the robot arm connecting bolt 12 is used on the connecting plate 11 to pass through the side of the connecting plate 11 away from the robot arm and extend into the quick-change connector 10 to be fastened to the quick-change connector 10.

[0110] In the above structure, due to the large difference in structural dimensions on both sides of the robot arm connection unit, a size structure in which the outer diameter of the flange mounting block 1001 is larger than the outer diameter of the bottom connecting block 1002 is adopted, and the outer diameter of the bottom connecting block 1002 is larger than the outer diameter of the connecting plate 11 for transition. The larger flange mounting block 1001 can ensure sufficient contact area with the robot arm, and thus can achieve sufficient connection strength.

[0111] In order to further achieve the strength of the structural connection within the robot arm connection unit, a plurality of groups of robot arm connection bolts 12 are provided on the connection plate 11 to achieve connection with the quick-change connection piece 10. Preferably, four groups of robot arm connection bolts 12 are evenly spaced around the connection plate 11. In addition, as mentioned above, the height of the bottom connection block 1002 is greater than the height of the flange mounting block 1001 and the connection plate 11, sufficient connection space can be provided for the robot arm connection bolts 12. At the same time, the connection plate 11 is connected to the quick-change connection piece 10 through the four groups of robot arm connection bolts 12. The above structure can ensure the connection stability of the internal structure of the robot arm connection unit, provide sufficient stability for the connection between the No. 2 connecting rod 6 and the material picking clamp 9 below, and even during the movement of the material picking clamp 9, to avoid the robot arm connection unit from being separated from the lower structure.

[0112] A No. 1 connecting block 1 is connected immediately below the robot arm connecting unit. The No. 1 connecting block 1 is required to realize the fastening and installation of the No. 1 connecting rod 3 and meet the adjustment requirements of the installation position and angle of the No. 1 connecting rod 3. In the present embodiment, the No. 1 connecting block 1 is arranged in a T-shape, including a horizontal end 101 of the No. 1 connecting block and a vertical end 102 of the No. 1 connecting block; wherein, the horizontal end 101 of the No. 1 connecting block is used to realize the connection with the robot arm connecting unit. For this purpose, the horizontal end 101 of the No. 1 connecting block extends toward both ends of the vertical end 102 of the No. 1 connecting block to form a No. 1 connecting block mounting end 103. When in use, the No. 1 connecting block connecting bolt 104 passes through the side of the No. 1 connecting block mounting end 103 away from the robot arm and extends into the robot arm connecting unit and is fastened to the connecting plate 11; and the No. 1 connecting block vertical end 102 is used to install the No. 1 connecting rod 3. For this purpose, a No. 1 connecting hole 2 parallel to the robot arm connecting unit is opened on the No. 1 connecting block vertical end 102. When in use, the No. 1 connecting rod 3 is passed through the No. 1 connecting hole 2 for installation.

[0113] As mentioned above, the No. 1 connecting block 1 is used to fasten and install the No. 1 connecting rod 3. At the same time, the No. 1 connecting block 1 is also needed to connect the No. 1 connecting rod 3 to the robot arm connection unit. Therefore, on the one hand, the No. 1 connecting block 1 is set to a T-shaped structure, and the No. 1 connecting block connecting bolt 104 is passed through the No. 1 connecting block horizontal end 101 to achieve the connection to the upper structure. Moreover, the No. 1 connecting block horizontal end 101 is arranged on both sides, which can help to achieve the stability and balance of the connection.

[0114] On the other hand, in actual use, it is necessary to take into account that the No. 1 connecting rod 3 is a cylindrical structure, and it is also necessary to adjust the installation length of the No. 1 connecting rod 3. Therefore, on the basis of realizing the fastening and installation of the cylindrical No. 1 connecting rod 3 through the connecting rod fastening unit, the No. 1 connecting rod 3 that can adjust the installation position front and rear can be locked at any length through the connecting rod fastening unit. Specifically, a connecting rod fastening unit is provided on the vertical end 102 of the No. 1 connecting block between the No. 1 connecting hole 2 and the horizontal end 101 of the No. 1 connecting block. When connected, the connecting rod fastening unit is vertical and against the No. 1 connecting rod 3.

[0115] like Figure 1 As shown, regarding the No. 2 connecting block 4, the difference between the No. 2 connecting block 4 and the No. 1 connecting block 1 is that the No. 1 connecting rod 3 and the No. 2 connecting rod 6 are installed in the No. 2 connecting block 4 at the same time, and the No. 2 connecting hole 17 and the No. 3 connecting hole 5 which are perpendicular to each other are opened in the No. 2 connecting block 4 accordingly. In order to realize the locking of the No. 1 connecting rod 3 and the No. 2 connecting rod 6 after adjusting the installation angle and length, a pair of mutually perpendicular connecting rod fastening units are arranged between the No. 2 connecting hole 17 and the No. 3 connecting hole 5, and the pair of connecting rod fastening units are respectively arranged perpendicularly to the adjacent No. 2 connecting hole 17 and the No. 3 connecting hole 5;

[0116] Under the action of the No. 2 connecting block 4, the above structure not only ensures the locking effect of the No. 1 connecting rod 3 and the No. 2 connecting rod 6, but also achieves the purpose of adjusting the installation position, length and angle of the No. 1 connecting rod 3 and the No. 2 connecting rod 6. At the same time, considering avoiding cumbersome structure and increasing the difficulty of operator training, it is preferred that each No. 2 connecting hole 17 and No. 3 connecting hole 5 still adopts the same connecting rod fastening unit structure as the No. 1 connecting hole 2;

[0117] However, since two sets of structure fixation need to be set on the same No. 2 connecting block 4, the structure distribution on the same No. 2 connecting block 4 must also meet the position requirements of the No. 1 connecting rod 3 and the No. 2 connecting rod 6. In addition, it is also necessary to consider that the strength of the overall structure will not be destroyed. Therefore, a pair of mutually perpendicular connecting rod fastening units are arranged between the No. 2 connecting hole 17 and the No. 3 connecting hole 5. At the same time, the No. 2 connecting hole 17 and its corresponding connecting rod fastening unit, the No. 3 connecting hole 5 and its corresponding connecting rod fastening unit also adopt a structure symmetrically arranged with respect to the center of the No. 2 connecting block 4, so that the structure of the No. 2 connecting block 4 is more compact and efficient.

[0118] On this basis, the second connecting block 4 acts as a connecting hub between the first connecting rod 3 and the second connecting rod 6, adjusting the horizontal direction to the vertical direction, so that the material removal clamp 9 installed at the bottom of the second connecting rod 6 can adjust its position in a direction suitable for the purpose of quickly removing the waste from the injection mold;

[0119] Since the directions of the forces acting on the No. 1 connecting rod 3 and the No. 2 connecting rod 6 are different, they are in a vertical structure to avoid stress concentration and damage. Both ends of the No. 2 connecting block 4 are arranged in an arc structure 41. The arc structures 41 on both sides are arranged perpendicular to each other, which can more effectively resist torque, improve the overall stability of the No. 2 connecting block 4 and the No. 1 connecting rod 3 and the No. 2 connecting rod 6, and enable the No. 2 connecting block 4 to disperse and transfer the load more evenly when subjected to external force;

[0120] Furthermore, the center of the arc structure 41 on each side is located on the same vertical center line as the center of the corresponding installed connecting rod, which can ensure that the force of the connecting rod is evenly distributed on the No. 2 connecting block 4, reduce stress concentration and reduce local pressure on the structure, avoid twisting and deformation, and help enhance the overall stability and durability of the No. 2 connecting block 4 structure.

[0121] like Figure 1 As shown, regarding the No. 3 connecting block 7, in this embodiment, the No. 3 connecting block 7 needs to be used to achieve the purpose of connecting the No. 2 connecting rod 6 and the material picking clamp 9. Preferably, the No. 3 connecting block 7 corresponds to the above-mentioned setting and includes an integrally formed connecting rod connecting end 71 and a material picking clamp connecting end 73. The connecting rod connecting end 71 is provided with a No. 4 connecting hole 72 passing through the No. 2 connecting rod 6. The material picking clamp connecting end 73 is integrally arranged on a side surface of the connecting rod connecting end 71. The material picking clamp connecting end 73 is arranged parallel to the No. 4 connecting hole 72. The material picking clamp connecting end 73 is formed on the side away from the connecting rod connecting end 71 to form a vertical mounting plane 8 for mounting the material picking clamp 9.

[0122] Since the installation direction of the material taking clamp 9 needs to be adjusted in angle and height according to the injection mold gate position, the structure of the connecting rod fastening unit can still be used in the No. 3 connecting block 7 to achieve locking. A connecting rod fastening unit is also provided between the connecting rod connecting end 71 and the material taking clamp connecting end 73, and the No. 2 connecting rod 6 is locked and installed on the connecting rod connecting end 71 through the connecting rod fastening unit;

[0123] When in use, the installation height of the No. 3 connecting block 7 on the No. 2 connecting rod 6 can be adjusted by adjusting the installation height, thereby achieving the purpose of adjusting the installation height of the material picking clamp 9. The installation angle of the No. 3 connecting block 7 can be adjusted by rotating the angle of the No. 3 connecting block 7 on the No. 2 connecting rod 6, thereby achieving the purpose of adjusting the installation angle of the material picking clamp 9.

[0124] Next, in this embodiment, the material taking clamp 9 can be controlled by a pneumatic device, so the installation method of the material taking clamp 9 is as simple as possible, which can avoid increasing the difficulty of operator training and reduce the impact on the working of the material taking clamp 9. The material taking clamp 9 is installed on the No. 3 connecting block 7 through the clamp connecting bolt 18, and the width of the material taking clamp connection end 73 is preferably set to be greater than the width of the connecting rod connection end 71. The extra position of the material taking clamp connection end 73 compared with the connecting rod connection end 71 provides an installation position for the clamp connection bolt 18;

[0125] At the same time, the width of the material picking jaw connecting end 73 is greater than the width of the material picking jaw 9. On the one hand, the wider material picking jaw connecting end 73 can better adapt to material picking jaws 9 of different sizes and types, improve the versatility and flexibility of the material picking jaw 9, and reduce the cost and time of replacing the jaws; on the other hand, the wider material picking jaw connecting end 73 can increase the contact area when connecting with the material picking jaw 9, thereby providing a more stable connection, which helps to prevent the material picking jaw 9 from falling off or loosening due to vibration or impact during operation, thereby ensuring the accuracy and stability of material picking.

[0126] It should be specifically explained that the structure of the connecting rod fastening unit used in the No. 1 connecting block 1, the No. 2 connecting block 4 and the No. 3 connecting block 7, the connecting rod fastening unit includes a fastening hole 13, a fastening nut 15 installed in the fastening hole 13, and a fastening bolt 14 connecting the fastening hole 13 and the fastening nut 15. Structurally, the fastening hole 13 and the corresponding connecting hole of the connecting rod are arranged perpendicular to each other and cross-overlap with each other, the side surface of the connecting rod passing through the corresponding connecting hole is located in the fastening hole 13, the fastening bolt 14 is installed in the fastening hole 13, the fastening nut 15 is sleeved on the end of the fastening hole 13 away from the bolt head of the fastening bolt 14, the fastening nut 15 and the fastening bolt 14 are connected by threads, and a profiling structure 16 is provided on the top side of the fastening nut 15 near the bolt head of the fastening bolt 14, the installation position of the fastening nut 15 is adjusted by the fastening bolt 14, and the profiling structure 16 is abutted against the side surface of the corresponding connecting rod to achieve the effect of adjusting the connection locking degree of the corresponding connecting rod.

[0127] In this embodiment, the locking of the No. 1 connecting rod 3 is taken as an example. The connecting rod fastening unit can realize the fastening and locking of the No. 1 connecting rod 3. Therefore, in this structure, the fastening hole 13 in the connecting rod fastening unit can pass through the No. 1 connecting rod 3, and the fastening nut 15 for locking the No. 1 connecting rod 3 is provided with a profiling structure, which can effectively resist and adhere to the arc surface of the No. 1 connecting rod 3 when locking.

[0128] When in use, the driving member used in the connecting rod fastening unit is a fastening bolt 14 that can pass through the fastening hole 13 and the fastening nut 15. Matching threads are provided on the inner and outer surfaces of the fastening bolt 14 and the fastening nut 15. By tightening, the installation is convenient, the adjustment time is saved, the installation efficiency is improved, and the training requirements for operators are reduced.

[0129] Preferably, in order to adapt to the purpose of locking the No. 1 connecting rod 3 with an adjusted installation position by the connecting rod fastening unit, and to achieve the effect of circumferentially abutting the side surface of the No. 1 connecting rod 3 to avoid rotation after locking, the fastening hole 13 is provided with a bolt head mounting hole 131 and a bolt rod mounting hole 132 sequentially opened along the axial direction corresponding to the fastening bolt 14, the fastening nut 15 and the No. 1 connecting rod 3, and a fastening nut mounting hole 133 is coaxially opened outside the bolt rod mounting hole 132;

[0130] The inner diameter of the bolt head mounting hole 131 is larger than the inner diameter of the bolt rod mounting hole 132, and the bolt head mounting hole 131 defines the movable range of the bolt head of the fastening bolt 14, and the height of the bolt head mounting hole 131 is not less than the height of the bolt head of the fastening bolt 14, so as to avoid the fastening bolt 14 extending out of the corresponding mounting block after installation and damaging other components;

[0131] The fastening nut mounting hole 133 not only matches the fastening nut 15, but also needs to correspond to the arc-shaped outer side structure of the No. 1 connecting rod 3. Therefore, the top side of the fastening nut mounting hole 133 is overlapped with the No. 1 connecting hole 2. In addition, in order to avoid damage to the No. 1 connecting rod 3 after the fastening nut 15 is excessively installed and locked upward after rotating along the fastening bolt 14, the top of the fastening nut mounting hole 133 is set not to exceed the center height of the No. 1 connecting hole 2. In addition, since the outer diameter of the fastening nut mounting hole 133 is always larger than the bolt rod mounting hole 132, the bolt rod mounting hole 132 can also play an effective limiting role.

[0132] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
