Description
Technical Field
[0001] This utility model relates to production equipment, specifically a bolt loading mechanism, a dual-purpose robotic arm, and injection molding equipment. Background Technology
[0002] In the production of some products, bolts need to be pre-installed on the components. Generally, the product is first injection molded, and then the bolts are installed on the product so that the product can be directly installed using the pre-installed bolts during subsequent assembly or to install other components. However, this method of installation is extremely burdensome in terms of production efficiency and labor costs. Therefore, it is possible to design a method that can pre-install bolts in the mold and then injection mold the product, directly molding the bolts onto the product. However, this poses a challenge to the bolt installation efficiency. Utility Model Content
[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a bolt loading mechanism, a dual-purpose robot and an injection molding equipment, which can facilitate the loading of bolts and improve production efficiency.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a bolt loading mechanism, including a bracket, a positioning plate mounted on the bracket, and an ejection mechanism mounted on the bracket. The positioning plate has grooves corresponding to the positions of each bolt, and the bottom of the grooves has through holes. The ejection mechanism includes a driving mechanism and a push rod corresponding to each through hole. The push rod is connected to the driving mechanism, and the driving mechanism is mounted on the bracket. The push rod is driven by the driving mechanism to insert into or disengage from the corresponding through hole. An anti-loosening mechanism for cooperating with the bolt is provided in the groove to form an interference fit or adsorption on the bolt, preventing the bolt from disengaging from the groove under gravity.
[0005] As a further improvement of this utility model, a magnetic attraction component is provided in the groove for adsorbing the bolt.
[0006] As a further improvement of this utility model, the magnetic suction component is ring-shaped, and the hollow position of the ring corresponds to the through hole so that the top rod can pass through.

[0008] As a further improvement of this utility model, when the magnetic component is installed in the assembly groove, the surface of the corresponding groove bottom is flush with or lower than the groove bottom.
[0009] As a further improvement of this utility model, the bracket is mounted on a movable mechanism, which drives the bracket to enter or leave the position of the mold.
[0010] A dual-purpose robotic arm is also provided, including a rotary drive mechanism and a bolt loading mechanism as described above.

[0013] The beneficial effects of this utility model are that the positioning plate can accurately position the bolt through the groove, and the anti-loosening mechanism can form an interference fit or adsorption effect on the bolt, effectively preventing the bolt from leaving the groove under the action of gravity and ensuring the stability of the bolt during the transfer process; the drive mechanism of the ejection mechanism drives the ejector rod to move, which can accurately push the bolt in the groove into the preset position of the mold, eliminating the need for subsequent manual filling operations, significantly improving production efficiency and reducing labor costs.

[0019] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.
[0020] Reference Figure 1-4As shown, this embodiment provides a bolt loading mechanism, including a bracket 1, a positioning plate 2 mounted on the bracket 1, and an ejection mechanism 3 mounted on the bracket 1. The positioning plate 2 is provided with grooves 21 corresponding to the positions of each bolt, and the bottom of the grooves 21 is provided with through holes 211. The ejection mechanism 3 includes a driving mechanism 31 and a push rod 32 corresponding to each through hole 211. The push rod 32 is connected to the driving mechanism 31, and the driving mechanism 31 is mounted on the bracket 1. The push rod 32 is driven by the driving mechanism 31 to insert into or disengage from the corresponding through hole 211. The grooves 21 are provided with anti-loosening mechanisms for cooperating with bolts to form interference or adsorption on the bolts, and to restrict the bolts from disengaging from the grooves 21 under the action of gravity.
[0021] The drive mechanism 31 is detachably fixed to the bracket 1 by bolts. The push rod 32 is fixed to the output end of the drive mechanism 31 by thread or welding to ensure the stability of the push rod 32 during movement. The positioning plate 2 is installed on the bracket 1 by screws, which facilitates subsequent maintenance or replacement of positioning plates 2 with different groove 21 specifications. In use, the operator places the bolts one by one into the groove 21 of the positioning plate 2 or pre-installs the bolts in the tooling. The moving mechanism drives the bracket 1 to move to the position of the tooling and moves the bracket 1 close to the tooling, so that the groove 21 on the positioning plate 2 is assembled with the corresponding bolt. The anti-dislodgement mechanism forms an interference fit or adsorption force on the bolt to prevent the bolt from falling off due to gravity during the movement of the bracket 1. When the bolt loading mechanism moves to the corresponding position of the mold, the drive mechanism 31 starts and drives the push rod 32 to move axially. After the push rod 32 passes through the through hole 211, it contacts the end face of the bolt and continues to push the bolt out of the groove 21 and into the preset installation position of the mold, completing the pre-loading of the bolt. This structure integrates bolt positioning, transfer, and loading through mechanical means, reducing manual intervention and improving loading efficiency. Simultaneously, the positioning function of the groove 21 improves bolt loading accuracy, reduces assembly errors, and ensures a secure connection between the bolt and the product after injection molding. The dimensions of the groove 21 are matched to the corresponding bolt size, preventing workers from manually placing bolts incorrectly into the groove. This fit also improves the product's yield rate, preventing the use of incorrectly sized bolts that could cause subsequent product malfunctions.
[0022] To facilitate the stable adsorption of bolts, in one alternative embodiment, a magnetic adsorption component 4 is provided in the groove 21 for adsorbing the bolts.
[0023] The magnetic suction component 4 is made of permanent magnet, and it is fixed to the positioning plate 2 by embedding or bonding. When the bolt is placed in the groove 21, the magnetic force generated by the magnetic suction component 4 can quickly attract the bolt, making the bolt stably attached to the bottom of the groove 21. Even if the bracket 1 tilts or moves slightly, the bolt will not fall off. Compared with the interference fit anti-loosening method, the magnetic suction structure does not require additional clamping operation, the bolt picking and putting resistance is smaller, the wear on the bolt surface can be reduced, and it is also easier for the subsequent push rod 32 to push the bolt out of the groove 21, further improving the smoothness of the filling process and improving the overall production efficiency.
[0024] Further optimization can be achieved by selecting the following method: the magnetic component 4 is ring-shaped, and the hollow position of the ring corresponds to the through hole 211 so that the top rod 32 can pass through.
[0025] The ring structure makes the magnetic attraction force of the bolt more evenly distributed, avoiding bolt displacement due to uneven attraction force, and further improving the positioning accuracy of the bolt in the groove 21. At the same time, the hollow design provides sufficient movement space for the push rod 32, avoiding interference of the magnetic attraction component 4 with the movement of the push rod 32, ensuring the normal operation of the ejection mechanism 3, making the connection between bolt attraction positioning and push loading action smoother, and improving the operational stability of the mechanism.
[0026] In some options, the bottom of the groove 21 is provided with an assembly groove 212 corresponding to the position of the magnetic component 4, for the magnetic component 4 to be inserted.
[0027] The dimensions of the mounting groove 212 match those of the magnetic component 4, and the depth of the mounting groove 212 matches the thickness of the magnetic component 4, facilitating the quick insertion and installation of the magnetic component 4. After the magnetic component 4 is inserted into the mounting groove 212, it can be fixed by adhesive bonding or interference fit.
[0028] To further optimize the structural rationality, in one optional embodiment, when the magnetic component 4 is installed in the assembly slot 212, the surface of the corresponding groove 21 bottom is flush with or lower than the groove 21 bottom.
[0029] When the surface of the magnetic component 4 is flush with or lower than the bottom of the groove 21, the bolt can make full contact with the magnetic component 4 and the bottom of the groove 21, resulting in greater stability.
[0030] In order to achieve position adjustment of the bracket 1, in some embodiments, the bracket 1 is mounted on a movable mechanism, which drives the bracket 1 into or out of the mold position.
[0031] The moving mechanism can be a cylinder, linear module, or robotic arm, etc. The fixed end of the moving mechanism is bolted to the frame of the injection molding equipment, and the moving end is fixedly connected to the bracket 1 via a flange or bolts to ensure a secure connection. The moving mechanism can drive the bracket 1 to move along a straight or curved trajectory according to a preset program, achieving precise alignment between the bolt loading mechanism and the mold. When bolt loading is required, the moving mechanism drives the bracket 1 closer to the mold; after loading is completed, the moving mechanism drives the bracket 1 away from the mold, avoiding interference with subsequent injection molding processes, making the entire production process more seamless, and further improving production efficiency.
[0032] This embodiment also provides a dual-purpose manipulator, including a rotary drive mechanism 31 and the bolt loading mechanism described above. The bracket 1 is connected to the rotary drive mechanism 31 to drive the bracket 1 to rotate. The bracket 1 is also provided with a clamp 5 for clamping the product formed in the mold.
[0033] The rotary drive mechanism 31 can be a rotary cylinder or a servo motor. The fixed end of the rotary drive mechanism 31 is mounted on the equipment frame, and the output end of the rotary drive mechanism 31 is fixedly connected to the bracket 1 via a coupling or flange. The clamp 5 is mounted on one side of the bracket 1 or the other end of the corresponding bolt loading mechanism via bolts, and is located on different sides of the bracket 1 from the positioning plate 2. In use, the movable mechanism drives the bracket 1 to move to the bolt feeding position. After the groove 21 of the positioning plate 2 absorbs the bolt, the movable mechanism drives the bracket 1 to move to the mold position, and the ejection mechanism 3 pushes the bolt into the mold. After the bolt loading is completed, the rotary drive mechanism 31 drives the bracket 1 to flip, so that the clamp 5 faces the molded product in the mold. After the clamp 5 clamps the product, the rotary drive mechanism 31 drives the bracket 1 to flip and reset again, and the movable mechanism drives the bracket 1 to move to the product unloading position. The clamp 5 releases to complete the product unloading. This dual-purpose robot integrates bolt loading and product clamping functions, eliminating the need for a separate material handling mechanism, simplifying the equipment structure, reducing the space occupied by the equipment, and enabling rapid switching between the two functions through the rotary drive mechanism 31, thereby improving the continuity of the production process and further enhancing production efficiency.
[0034] This embodiment also provides an injection molding equipment, including a frame, a mold mounted on the frame, and an injection mechanism connected and cooperating with the mold. The aforementioned bolt loading mechanism is mounted on the frame.
[0035] The mold is bolted to the worktable of the machine frame. The injection port of the injection molding mechanism is connected to the feed port of the mold. The movable mechanism of the bolt loading mechanism is fixed to the machine frame with bolts, and the bolt loading mechanism is set to correspond to the preset loading position of the mold. During production, the bolt loading mechanism first pre-loads the bolts into the mold. Then, the injection molding mechanism injects molten raw material into the mold. The raw material is formed in the mold and firmly bonded to the bolts. After cooling, the mold is opened to obtain the pre-loaded bolted product. This injection molding equipment realizes the integrated production of bolt pre-loading and injection molding, eliminating the need for subsequent manual bolt loading, significantly improving production efficiency, reducing labor costs, and achieving higher bolt loading accuracy and more stable product quality.
[0036] This embodiment also provides another injection molding equipment, including a frame, a mold mounted on the frame, and an injection mechanism connected and cooperating with the mold. The aforementioned dual-purpose robot is mounted on the frame.
[0037] Both the mold and the injection molding mechanism are mounted on the frame. The rotary drive mechanism 31 of the dual-purpose robot is fixedly mounted on the frame, and the movement trajectory of the dual-purpose robot covers the filling and unloading positions of the mold. During production, the dual-purpose robot first fills the bolts into the mold, and the injection molding mechanism performs injection molding. After the product is formed, the dual-purpose robot uses the clamp 5 to pick up the formed product and transfer it to the unloading position, realizing the integrated operation of bolt filling, injection molding, and product unloading. The production process is more streamlined, the equipment is more automated, and it can further improve production efficiency, reduce manual intervention, and is suitable for mass production scenarios.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
