Description

Technical Field

[0001] This utility model relates to the field of robotic arm technology, and in particular to a robotic arm end-effector gripping device for manufacturing electronic product casings. Background Technology

[0002] In the injection molding process of electronic products (such as walkie-talkies), it is often necessary to pre-fix metal inserts such as charging contacts and connecting pieces in the mold cavity, and then close the mold for injection molding, so that the plastic covers the metal inserts to form an integrated structure.

[0003] Currently, most installations in the industry are done manually, which can lead to low efficiency. Some companies use small pneumatic grippers to pick up the inserts. However, due to the small size of these inserts, it is difficult to control the gripping force precisely when they are picked up by the grippers. This can easily cause the metal inserts to deform or scratch their surfaces. The inserts are also prone to deflection within the grippers, making it impossible to ensure that they are accurately placed into the corresponding slots in the mold. This results in lower product quality. Furthermore, the gripper structure is relatively complex and lacks flexibility in confined spaces. Utility Model Content

[0004] This utility model discloses a robotic arm end-effector gripping device for the production of electronic product casings. It mainly solves the problem that in the existing injection molding process of electronic products, the insertion of small metal inserts such as charging contacts or connecting pieces into the mold is mostly done manually, resulting in low efficiency, or the use of pneumatic grippers results in unstable injection molding quality.

[0005] To achieve the aforementioned objective, the technical solution of this utility model is implemented as follows: This utility model provides a robotic arm end-effector gripping device for manufacturing electronic product casings, including a connecting plate, a movable plate, and a base plate mounted on the movable plate for connecting to the end of the robotic arm. The movable plate is connected to the connecting plate through a buffer assembly. The substrate has at least one groove for accommodating a metal insert on the side away from the connecting plate. The inner contour of the groove matches the outer contour of the metal insert. The substrate has at least one negative pressure channel for connecting to an external negative pressure machine inside. One end of the negative pressure channel is connected to a negative pressure pipe, and the other end is connected to the groove.

[0006] In one embodiment, the negative pressure channel includes at least one negative pressure interface for connecting to a negative pressure pipe, at least one negative pressure air inlet for communicating with a corresponding groove, and a connecting channel. The negative pressure interface and the negative pressure air inlet are connected by the connecting channel, and the number of negative pressure air inlets corresponds to the number of grooves.

[0007] In one embodiment, when the number of grooves is two or more, the negative pressure channel further includes an air inlet connecting pipe, and the connecting channel is connected to multiple negative pressure air inlets through the air inlet connecting pipe.

[0008] In one embodiment, the buffer assembly includes at least one guide rod, a guide sleeve mounted on a connecting plate and slidably engaged with the guide rod, and an elastic element sleeved on the guide rod, wherein the two ends of the elastic element abut against or are connected to the guide sleeve and the movable plate, respectively.

[0009] In one embodiment, the connecting plate has a through hole corresponding to the position of the guide rod, the end of the guide rod away from the movable plate passes through the through hole, and a limiting plate is installed on the end of the guide rod away from the movable plate, the outer diameter of the limiting plate being larger than the diameter of the through hole.

[0010] In one embodiment, the plurality of grooves are arranged in a straight line or in a circular pattern.

[0011] In one embodiment, the movable plate is provided with at least two locating pins on the side away from the connecting plate.

[0012] The advantages or beneficial effects of the above technical solution include at least the following: When gripping metal inserts, due to the arrangement of the connecting plate, movable plate, buffer assembly, and base plate, the groove on the base plate and the negative pressure channel connected to it, during operation, the external negative pressure machine can draw air into the groove through the negative pressure channel, creating a negative pressure in the groove, so as to adsorb the corresponding metal insert into the groove, and then accurately place the metal insert into the preset insert slot in the mold cavity. After the negative pressure is turned off, the metal part naturally detaches, the robotic arm retracts, and one insert is loaded, thereby improving installation efficiency and minimizing damage to the metal insert to ensure the quality of the finished product; at the same time, the buffer assembly can change the hard contact when the robotic arm drives the gripping device to contact the mold to a soft contact, avoiding damage from hard contact.

[0020] The names of the messages or information exchanged between the multiple devices in this embodiment of the invention are for illustrative purposes only and are not intended to limit the scope of these messages or information.

[0021] See Figures 2 to 5 The present invention provides a robotic arm end gripping device for manufacturing electronic product casings, including a connecting plate 1, a movable plate 2 and a base plate 4 mounted on the movable plate 2 for connecting to the end of the robotic arm. The movable plate 2 is connected to the connecting plate 1 through a buffer assembly 3. The substrate 4 has at least one groove 41 for accommodating a metal insert on the side away from the connecting plate 1. The inner contour of the groove 41 matches the outer contour of the metal insert. The substrate 4 has at least one negative pressure channel 42 for connecting to an external negative pressure machine. One end of the negative pressure channel 42 is connected to a negative pressure pipe 43, and the other end is connected to the groove 41.

[0022] Before the gripping device of this application grips, the direction and position of the metal insert can be adjusted by vibration of a vibratory feeder to facilitate gripping by the gripping device. The vibratory feeder is an existing device for adjusting the orientation of the workpiece, and will not be described in detail here.

[0023] With the above structure, when gripping metal inserts, the connection plate 1, movable plate 2, buffer assembly 3, and base plate 4 are used. The groove 41 on the base plate 4 and the negative pressure channel 42 connected to it allow the external negative pressure machine to draw air into the groove 41 through the negative pressure channel 42 during operation, creating a negative pressure in the groove 41. This facilitates the adsorption of the corresponding metal insert into the groove 41, and then the metal insert is accurately placed into the preset insert slot in the mold cavity. After the negative pressure is turned off, the metal part naturally detaches, the robotic arm retracts, and one insert is loaded, thereby improving installation efficiency and minimizing damage to the metal insert to ensure the quality of the finished product. At the same time, the buffer assembly 3 transforms the hard contact between the robotic arm and the gripping device and the mold into a soft contact, preventing damage from hard contact.

The negative pressure interface 421 and the negative pressure air inlet 422 are connected through the connecting channel 423, and the number of negative pressure air inlets 422 corresponds to the number of grooves 41.

[0025] When there are two or more grooves 41, the negative pressure channel 42 also includes an air intake connecting pipe 424, and the connecting channel 423 is connected to multiple negative pressure air inlets 422 through the air intake connecting pipe 424.

[0026] Multiple grooves 41 are arranged in a straight line or in a circle. This embodiment refers to... Figure 1 The grooves 41 are arranged in a straight line and multiple negative pressure channels 42 are adopted. Each negative pressure channel 42 can be provided with a connecting channel 423. The connecting channel 423 is used to connect multiple negative pressure air inlets 422 to each other. The negative pressure interface 421 is connected to the negative pressure air inlet 422, so that one negative pressure pipe 43 can connect multiple grooves 41.

[0027] In one embodiment, see Figure 2 , Figure 7 , Figure 8 and Figure 1 In order to buffer the substrate 4 when it contacts the mold, the buffer assembly 3 includes at least one guide rod 31, a guide sleeve 32 mounted on the connecting plate 1 and slidingly engaged with the guide rod 31, and an elastic member 33 sleeved on the guide rod 31. The two ends of the elastic member 33 abut against or connect to the guide sleeve 32 and the movable plate 2, respectively.

[0028] The connecting plate 1 has a through hole 11 at the position corresponding to the guide rod 31. The end of the guide rod 31 away from the movable plate 2 passes through the through hole 11. A limit plate 34 is installed at the end of the guide rod 31 away from the movable plate 2. The outer diameter of the limit plate 34 is larger than the diameter of the through hole 11.

[0029] In one embodiment, see Figure 2 , Figure 7 , Figure 8 , Figure 9 and ​ At least two positioning pins 5 are provided on the side of the movable plate 2 away from the connecting plate 1. A positioning groove 6 is provided at the corresponding position of the injection mold.
