Description

Technical Field

[0001] The utility model relates to the field of manipulators, and more specifically, to a mechanical gripper mechanism. Background Art

[0002] When injection molding some products with inserts, in order to improve production efficiency, mechanical grippers are often used to put the inserts into the plastic mold and take the products out of the plastic mold after the products are formed.

[0003] The existing mechanical grippers need to first take out and place the products formed by the plastic mold, and then the mechanical grippers clamp the inserts from the station where the inserts are placed and put the inserts into the plastic mold for molding. The mechanical grippers cannot clamp the inserts and the formed products at the same time, so that the mechanical grippers cannot immediately put the inserts into the plastic mold for molding after taking out the products from the plastic mold. Summary of the Utility Model

[0004] Aiming at the above defects of the prior art, a mechanical gripper mechanism is provided.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a mechanical gripper mechanism, including a base. Two first grippers are arranged at the top end of the base. The two first grippers are arranged in the left-right direction. A telescopic cylinder with an output end facing the top end of the base is arranged on the right side wall of the base. The output end of the telescopic cylinder is connected with a horizontal plate. A support plate extending downward is arranged on the horizontal plate. One end of the support plate far away from the horizontal plate is provided with a mounting plate. The mounting plate is located at the rear lower part of the horizontal plate. Two second grippers are arranged at the top end of the mounting plate. The two second grippers are arranged in the left-right direction.

[0006] Preferably, two spaced convex blocks and a bracket supporting the two convex blocks are arranged at the top end of the base. The two first grippers are both located between the two convex blocks. The heights of the two convex blocks are the same as the height of the clamping parts of the first grippers. Two semi-cylindrical notches are arranged at the top end of each convex block. The two notches are in one-to-one correspondence with the clamping parts of the two first grippers. The two notches extend in the front-back direction.

[0007] Preferably, adsorption holes are arranged on the bottom surface of each notch of the convex block. A vacuum channel communicated with the adsorption holes is also arranged on the convex block. One end of the vacuum channel penetrates through the side wall of the convex block.

[0008] Preferably, the bracket includes a connecting plate, two support plates and two vertical plates. The connecting plate is disposed at the top end of the base. Two avoidance through holes for avoiding corresponding first clamping jaws are provided on the connecting plate. The two first clamping jaws pass through the corresponding avoidance through holes. The two vertical plates are correspondingly disposed at the front and rear ends of the connecting plate. The two support plates are horizontally disposed at the top ends of the two corresponding vertical plates. The two bumps are disposed at the top ends of the two corresponding support plates.

[0009] Preferably, the two first clamping jaws are arranged in a staggered manner in the left - right direction, and the two second clamping jaws are arranged in a staggered manner in the left - right direction.

[0010] Preferably, the base is a rectangular plate structure, and the upper part of the telescopic cylinder is connected to the right side wall of the base.

[0011] The beneficial effects of the present utility model are as follows: The insert is clamped by the two first clamping jaws. After the plastic mold forms a good product, the telescopic cylinder extends to push the two second clamping jaws, so that the two second clamping jaws approach the plastic mold, facilitating the two second clamping jaws to take out the product in the plastic mold. Then the two first clamping jaws immediately put the clamped insert into the injection mold. When the first clamping jaws put the insert into the injection mold, the telescopic cylinder contracts, so that the two second clamping jaws move away from the injection mold for avoidance, preventing the two second clamping jaws from interfering with the injection mold. Subsequently, when the injection mold forms a product, the two first clamping jaws clamp the insert again, saving the time for the mechanical clamping jaws to clamp the insert again and improving the production efficiency.

[0015] In order to make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model. Obviously, the described embodiments are partial embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. In addition, the directional terms mentioned in the present utility model, such as "upper", "lower", "front", "rear", "left", "right", "inner", "outer", etc., are only references to the directions in the attached drawings. The directional terms used are for better and clearer illustration and understanding of the present utility model, rather than indicating or implying the directions that the present utility model must have. Therefore, it should not be construed as a limitation to the present utility model.

[0016] As shown in the embodiments of the present utility model Figures 1 to 2 a mechanical gripper mechanism includes a base 1. The base 1 is a rectangular plate structure. The bottom end of the base 1 is connected to a robotic arm. Two first grippers 2 are provided at the top end of the base 1. The two first grippers 2 are arranged in the left-right direction. A telescopic cylinder 3 with an output end facing upward is provided on the right side wall of the base 1. The upper part of the telescopic cylinder 3 is connected to the right side wall of the base 1. The telescopic cylinder 3 is located at a position on the right side wall of the base 1 close to the front side. The output end of the telescopic cylinder 3 is connected to a horizontal plate 30. A support plate 31 extending downward is provided at the front side of the bottom end of the horizontal plate 30. An installation plate 32 is provided at the end of the support plate 31 far from the horizontal plate 30, that is, an installation plate 32 is provided at the bottom end of the support plate 31. The installation plate 32 is located at the rear lower part of the horizontal plate 30. The front side of the top end of the installation plate 32 is connected to the bottom end of the support plate 31. The horizontal plate 30, the support plate 31, and the installation plate 32 are integrally formed. Two second grippers 4 are provided at the top end of the installation plate 32. The two second grippers 4 are arranged in the left-right direction.

[0017] The two first grippers 2 are used to grip the insert. After the plastic mold forms the product, the telescopic cylinder 3 extends to push the two second grippers 4, making the two second grippers 4 close to the plastic mold, facilitating the two second grippers 4 to take out the product in the plastic mold. Then, the two first grippers 2 put the gripped insert into the injection mold. When the first grippers 2 put the insert into the injection mold, the telescopic cylinder 3 contracts, making the two second grippers 4 move away from the injection mold for avoidance, preventing the two second grippers 4 from interfering with the injection mold. Subsequently, when the injection mold forms the product, the two first grippers 2 grip the insert again, saving the time for the mechanical gripper to grip the insert again and improving the production efficiency.

[0018] Further improvement, as shown in Figure 1 and Figure 2As shown in the figure, two bumps 5 arranged at intervals in the front-back direction are provided at the top of the base 1, and a bracket for supporting the two bumps 5. Both of the first jaws 2 are located between the two bumps 5. The bracket includes a connecting plate 6, two support plates 60 and two vertical plates 61. The connecting plate 6 is arranged at the center position of the top of the base 1. Two avoidance through holes for avoiding the corresponding first jaws 2 are provided on the connecting plate 6. Both of the first jaws 2 pass through the corresponding avoidance through holes. The two vertical plates 61 are correspondingly arranged at the front and rear ends of the connecting plate 6. The two support plates 60 are horizontally arranged at the tops of the two corresponding vertical plates 61. The rear side of the bottom end of the front support plate 60 is connected to the vertical plate 61, and the front side of the bottom end of the rear support plate 60 is connected to the vertical plate 61. The two bumps 5 are arranged at the tops of the two corresponding support plates 60. The bump 5 is of a cuboid structure. Both of the two bumps 5 extend in the left-right direction. The heights of the two bumps 5 are the same as the height of the clamping part of the first jaw 2. Two semi-cylindrical notches 50 are provided at the top of each bump 5. The two notches 50 are in one-to-one correspondence with the clamping parts of the two first jaws 2. The two notches 50 extend in the front-back direction. Through the notches 50 on the bump 5, the round bar-shaped inserts clamped by the first jaws 2 can be limited, preventing the inserts from shifting during movement, so that the round bar-shaped inserts can be accurately placed into the injection mold.

[0019] Further improvement, as Figure 1 and Figure 2 As shown in the figure, the bump 5 is provided with adsorption holes 51 on the bottom surface of each notch 50. A vacuum channel 52 communicating with the adsorption holes 51 is also provided on the bump 5. One end of the vacuum channel 52 penetrates the side wall of the bump 5. The vacuum channel 52 of the front bump 5 penetrates the front side wall of the corresponding bump 5, and the vacuum channel 52 of the rear bump 5 penetrates the rear side wall of the corresponding bump 5. The vacuum channel 52 is connected to a vacuum pump. The adsorption holes 51 perform vacuum adsorption when the mechanical jaw clamps the round bar-shaped insert, making the clamping of the round bar-shaped insert more stable.

[0020] Further improvement, as Figure 1 As shown in the figure, the two first jaws 2 are arranged in a staggered manner in the left-right direction and are also staggered in the front-back direction, so that the two first jaws 2 can be closer in the left-right direction and there will be no interference when clamping the insert. The two second jaws 2 are arranged in a staggered manner in the left-right direction and are also staggered in the front-back direction, so that the two second jaws 2 can be closer in the left-right direction and there will be no interference when clamping the product, making the structure of this mechanical jaw more compact.
