[0002] In order to achieve cost reduction and efficiency improvement and to ensure the labor intensity of workers and make full use of injection molding machines, automated production is a popular development direction. Regarding the manipulator used in the injection molding process, the existing public patent (publication number CN217622003 U) discloses a five-axis injection molding manipulator, including a support seat and a base, a base is fixedly installed on the top of the support seat, a No. 1 mounting frame is fixedly installed on the top of the base, a No. 1 linear guide is fixedly installed on the No. 1 mounting frame, a machine head is slidably installed on one end of the No. 1 linear guide, and a No. 1 mounting frame is arranged at the upper end of the base, and the machine head is slidably installed on the No. 1 mounting frame, and the No. 2 mounting frame is installed on one side of the machine head, and a No. 1 moving unit and a No. 2 moving unit are slidably installed on the No. 2 mounting frame, and a No. 1 lifting rod and a No. 2 lifting rod are respectively installed on the No. 1 moving unit and the No. 2 moving unit, and a flipper and a pneumatic clamp are respectively installed at the bottom of the No. 1 lifting rod and the No. 2 lifting rod, so that the workpiece is flipped and clamped during the injection molding process, and the two linear guides and the two moving units are used to realize the operation of the manipulator in three degrees of freedom X, Y, and Z.

[0003] In the above-mentioned manipulator, the movement of the head is achieved by the linear movement of the guide block along the guide rail, but the limit structure causes the friction damping of the head to be large, thereby increasing its corresponding driving energy consumption. To this end, we provide a five-axis injection molding manipulator to solve the above-mentioned problems. Utility Model Content

During this process, the roller supports the base plate and assists the movement of the base plate with its own rotation. The guide block is used to assist the movement balance of the base plate. Compared with the current linear drive structure, the addition of the roller can effectively reduce the movement damping of the base plate and reduce the energy consumption of the linear drive, making the linear movement of the transmission component more convenient and efficient.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example

[0024] See also Figure 1-5 The utility model is a five-axis injection molding robot, comprising a robot body 1; the robot body 1 comprises a machine platform 11, an electric control box 17 fixed to the side of the machine platform 11, a frame 13 fixed to the upper side of the machine platform 11, a guide rail 15 installed on the upper side of the frame 13, and a transmission component 12 movably matched with the guide rail 15; the transmission component 12 comprises a hood 121, a bottom plate 126 fixed to the bottom of the hood 121, a guide block 123 fixed at the bottom corner of the bottom plate 126, a roller 124 movably arranged in the middle position of the bottom plate 126, and a sheet metal part 125 fixed to the side of the bottom plate 126; the guide block 123 cooperates with the guide rail 15, and the circumference of the roller 124 rolls and fits with the upper side of the frame 13.

[0025] Specifically, in the five-axis injection molding robot proposed in the present application, by adding a roller 124 structure in the transmission component 12, the transmission component 12 moves linearly along the upper side of the frame 13 when it is linearly driven. During this process, the roller 124 supports the base plate 126 and assists the movement of the base plate 126 with its own rotation. The guide block 123 is used to assist the movement balance of the base plate 126. Compared with the current linear drive structure, the addition of the roller 124 can effectively reduce the movement damping of the base plate 126 and reduce the linear drive energy consumption, making the linear movement of the transmission component 12 more convenient and efficient.

[0026] Furthermore, a heat dissipation area is provided on the side of the hood 121, and a notch 122 is provided at the lower front corner of the hood 121, a transmission chain 16 is passed through the notch 122, and a side fixing member 14 is fixed to the other end of the transmission chain 16, and the side fixing member 14 is fixed to the side of the frame 13.

[0027] Specifically, the heat dissipation area opened on the side of the hood 121 is used for heat dissipation and ventilation of its built-in components. The notch 122 opened at the lower corner of the front side of the hood 121 is used for the installation of a transmission chain 16, which cooperates with the internal transmission elements of the hood 121. Under the connection action of the side fixing part 14, the transmission chain 16 forms a linear drive system of the transmission component 12. Specific embodiment 2

[0029] See also Figure 1 and Figure 2 On the basis of the first specific embodiment, one end of the linear rail 18 is fixed inside the hood 121, and the front of the linear rail 18 is movably provided with a support arm 112 and a support arm 2 113 through a connecting seat 110, and mounting ends are fixed at the bottom of the support arm 112 and the support arm 2 113.

[0030] Specifically, the linear rail 18 is used to guide the movement of the connecting seat 110. During the linear movement of the connecting seat 110, the linear movement of the corresponding supporting arm 1 112 and the supporting arm 2 113 is driven.

[0031] Furthermore, the support arm 1 112 is movably installed on the outside of the connecting seat 110 via the transmission chain 2 111, and the support arm 2 113 is movably installed on the outside of the connecting seat 110 via the transmission chain 3 114. The back of the connecting seat 110 is connected to the transmission chain 4 19, and the transmission chain 4 19 is arranged one-to-one with the connecting seat 110.

[0032] Specifically, two connecting seats 110 are arranged in parallel, wherein the support arm 112, the transmission chain 2 111 and the transmission chain 4 19 constitute an independent driving system, and the support arm 2 113, the transmission chain 3 114 and the transmission chain 4 19 constitute another independent driving system. Under the driving action of the two independent driving systems, the support arm 112 and the support arm 2 113 realize coordinate movement. The driving of the support arm in the five-axis injection molding machine is far more than the above structure. Since the driving of the support arm is not a necessary technical feature of the present application, no further restrictive description is made for its driving structure.
