Description

Technical Field

[0001] The utility model relates to the technical field of fixture structures, and more specifically, to a double-sided multi-station fixture assembly and an injection molded part blanking system. Background Art

[0002] After an injection molding machine injects multiple products at one time, it is necessary to blank the products and the sprue. However, the blanking space of some injection molding machines is relatively narrow, and the sprue and the products are respectively on opposite sides within the blanking space. Therefore, when blanking, the sprue and the products need to be blanked in sequence. For example, after all the products on one side are blanked using a product blanking fixture, the sprue blanking fixture is then switched to blank the sprue on the other side. This results in a longer blanking process and affects production efficiency. In addition, since the fixture structures for gripping the sprue and the products are different, two sets of fixtures need to be set up, and different fixtures need to be switched during the blanking process to blank the products and the sprue respectively. Summary of the Utility Model

[0003] The utility model discloses a double-sided multi-station fixture assembly, aiming to improve the low blanking efficiency of injection molded products in a narrow space.

[0004] The utility model adopts the following solutions:

[0005] A double-sided multi-station fixture assembly includes a fixture main body adapted to be connected to a robot arm. On one side of the fixture main body, there is at least one row of first jaw assemblies adapted to grip products, and on the other side of the fixture main body, there is at least one row of second jaw assemblies adapted to grip the sprue. The first jaw assemblies and the second jaw assemblies are staggeredly distributed in the insertion direction when the fixture main body is inserted into the injection molding machine, so as to reduce the installation width of the entire fixture assembly and thus adapt to the narrow blanking space of the injection molding machine.

[0006] Furthermore, a vision detection device is provided at the top of the fixture main body for positioning the product position.

[0007] Furthermore, a number of pneumatic connectors are respectively provided on both sides of the fixture main body, and each side of the pneumatic connectors is connected to the first jaw assemblies or the second jaw assemblies on the same side to drive the first jaw assemblies and the second jaw assemblies to work.

[0008] Furthermore, each row of the first jaw assemblies is provided with at least sixteen first jaws, and each row of the second jaw assemblies is provided with at least sixteen second jaws.

[0009] Furthermore, the pneumatic connectors are lower than the heights of the first jaws and the second jaws along the width direction of the fixture main body.

[0010] Further, one end of the fixture assembly is provided with a connecting through-hole, and a plurality of mounting holes are arranged around the circumference of the connecting through-hole. The connecting through-hole and the mounting holes are adapted to be connected to a manipulator.

[0011] The present utility model also provides an injection molding part blanking system, which includes a manipulator and an XY-axis module. The manipulator is connected with a double-sided multi-station fixture assembly as described in any one of the above. The XY-axis module is adapted to carry a material tray to transfer the material tray between the upper tray position, the feeding position and the lower tray position; the manipulator is configured to be able to drive the fixture assembly to extend into the blanking space of the injection molding machine, so as to clamp a whole row of products through the first jaw assembly, and continue to drive the fixture assembly to move after the first jaw assembly clamps the product so that the second jaw assembly clamps the material head; the manipulator is adapted to drive the first jaw assembly to move to the feeding position to place the products in the material tray and place the material head clamped by the second jaw assembly in the material discharging frame after the first jaw assembly and the second jaw assembly respectively clamp the products and the material head.

[0012] Beneficial effects:

[0013] Through the solution of the present utility model, when the fixture assembly extends into a narrow blanking space, the products and the material heads located on the opposite sides can be blanked respectively, and multiple products and material heads can be blanked at one time, greatly improving the blanking efficiency. By staggering the first jaw assembly and the second jaw assembly into two rows to face the opposite sides of the fixture body, the width of the clamping assembly can be reduced to adapt to the narrow blanking space, and the products and the material heads on both sides can be clamped and blanked at one time after extending into the blanking space, improving the blanking efficiency.

Detailed implementation mode

[0019] Combined with Figures 1 to 4 As shown in the figure, this embodiment provides an injection molded part blanking system, including a manipulator 2 and an XY-axis module 3. The manipulator 2 is connected with the double-sided multi-station fixture assembly described in any one of the above. The double-sided multi-station fixture assembly includes a fixture main body 51 adapted to be connected to the manipulator 2. On one side of the fixture main body 51, there is at least one row of multiple first jaw assemblies 52 adapted to clamp products, and on the other side of the fixture main body 51, there is at least one row of multiple second jaw assemblies 53 adapted to clamp the material heads; the first jaw assemblies 52 and the second jaw assemblies 53 are staggeredly distributed in the extending direction when the fixture main body 51 extends into the injection molding machine 1, so as to reduce the width of the entire fixture assembly 5 and thus adapt to the narrow blanking space 11 of the injection molding machine 1.

[0020] The XY-axis module 3 is adapted to carry the material tray 4 to transfer the material tray 4 between the upper tray position, the feeding position and the lower tray position; the manipulator 2 is configured to be able to drive the fixture assembly 5 to extend into the blanking space 11 of the injection molding machine 1, so as to clamp a whole row of products through the first jaw assemblies 52, and continue to drive the fixture assembly 5 to move after the first jaw assemblies 52 clamp the products so that the second jaw assemblies 53 clamp the material heads; the manipulator 2 is adapted to drive the first jaw assemblies 52 to move to the feeding position to place the products in the material tray 4 and place the material heads clamped by the second jaw assemblies 53 in the discharging frame after the first jaw assemblies 52 and the second jaw assemblies 53 clamp the products and the material heads respectively. Through the first jaw assemblies 52 arranged in a whole row, the products can be placed in the material tray 4 row by row, which is convenient for arranging the trays.

[0021] Combined with Figure 4 As shown in the figure, in this embodiment, after the injection molding machine 1 finishes injection molding and opens the mold, a narrow blanking space 11 is formed. A whole row of material heads is exposed on one side of the blanking space 11, and products are exposed on the opposite side. After the manipulator 2 drives the fixture assembly 5 into the blanking space 11, it first locates one side of the product, clamps all the products, and then pulls out a certain distance in the direction of the material head to pull out the products from the mold; then positions the second jaw assemblies 53 at the material heads and pulls out the material heads. After the material heads and the products are pulled out, the manipulator 2 drives the fixture assembly 5 to move to the material tray 4, places the products in the material grooves of the material tray 4; finally, places the material heads in the discharging frame. By entering the blanking space 11 once, the material heads and the products can be pulled out at the same time and placed in the corresponding positions, improving the blanking efficiency. When arranging the trays, since the first jaw assemblies 52 are arranged in rows, they are also placed in the material tray 4 row by row, with high tray arranging efficiency.

[0022] Combined with Figures 1 to 3As shown, the fixture body 51 can be set in a T shape, and at least one row of first jaw assemblies 52 is provided at its topmost end. The first jaw assemblies 52 include a plurality of first jaws for gripping products, and all the first jaws face the same side and are neatly arranged. The main body parts of the first jaws can be retracted into the fixture body 51 to reduce the width of the entire fixture assembly 5, so as to be suitable for extending into the narrow blanking space 11.

[0023] The second jaw assembly 53 is arranged at a position below the first jaw assembly 52 and is parallel to the arrangement direction of the first jaw assembly 52. The second jaw assembly 53 includes a plurality of second jaws, and the orientation of the clamping parts of the second jaws is opposite to that of the first jaws, so that the material heads on the other side can be clamped. The main body parts of the second jaws are also retracted into the fixture body 51 to reduce the width of the entire fixture assembly 5.

[0024] On both sides of the fixture body 51, a number of pneumatic connectors 54 are respectively provided. Each side of the pneumatic connectors 54 is connected to the first jaw assembly 52 or the second jaw assembly 53 on the same side to drive the first jaw assembly 52 and the second jaw assembly 53 to work. The position where the pneumatic connectors 54 are located is lower than the height of the first jaws and the second jaws along the width direction of the fixture body 51. This setting can prevent the pneumatic connectors 54 from affecting the width range of the entire fixture assembly 5 and restricting the movement range of the fixture assembly 5 in the blanking space 11.

[0025] In this embodiment, each row of the first jaw assemblies 52 is provided with at least sixteen first jaws, and each row of the second jaw assemblies 53 is provided with at least sixteen second jaws. It should be noted that in other embodiments, multiple groups of parallel first jaw assemblies 52 and second jaw assemblies 53 can be provided, and the number of jaws in each jaw assembly is not limited to sixteen. The first jaws and the second jaws are both driven in a pneumatic manner.

[0026] It should be noted that in this embodiment, the width of the fixture assembly 5 refers to the distance between the clamping plane where the clamping ends of the first jaw assembly 52 are located and the clamping plane where the clamping ends of the second jaw assembly 53 are located.

[0027] In this embodiment, one end of the fixture assembly 5 is provided with a connection through hole 55, and a number of mounting holes 56 are arranged around the circumference of the connection through hole 55. The connection through hole 55 and the mounting holes 56 are suitable for connecting with the manipulator 2. The manipulator 2 is supported through the connection through hole 55 and is used for positioning through the mounting holes 56. Adjusting the connection positions of different mounting holes 56 can adjust the connection angle between the manipulator 2 and the fixture body 51.

[0028] In a preferred embodiment, a vision detection device 57 is provided at the top of the fixture body 51 for positioning the product. The vision detection device 57 can be used to detect the position of the product, thereby improving the accuracy of picking up the product.

[0029] Through the solution of this embodiment, the product and the blank can be unloaded at one time, improving the unloading efficiency.

[0030] It should be understood that the above are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention.
