A limit member 13 is also provided on one side of the suction cup. The limit member 13 is sleeve-shaped and fixedly provided on the connection seat. When the suction cup 11 absorbs the mold, the limit member 13 abuts against one side of the mold.

[0067] In some embodiments, reference Figures 1 to 7 The tape sealing device further includes a third driving mechanism 50 for driving the clamp mechanism 10 to rotate. In this embodiment, the third driving mechanism 50 includes a third motor disposed on one side of the main shaft 12 and a third transmission assembly 51 connecting the rotating shaft of the third motor and the main shaft 12. The third transmission assembly may be a gear transmission assembly, a pulley transmission assembly, a sprocket transmission assembly, etc.

[0068] In some embodiments, reference Figures 1 to 7 , the first driving mechanism 30 comprises:

[0069] A sliding assembly 32, a mounting seat 32a rotatably connected to the main shaft, a sliding member slidably connected to the mounting seat 32a, and the sealing member 21 is arranged on the sliding member;

[0070] an elastic member, connecting the mounting seat 32a and the sliding member, and used for applying an elastic force toward the mounting portion to the sliding member so that the sealing member 21 abuts against the outer peripheral wall of the mold;

[0071] The first driving member 33 is used for applying a first driving force to the sealing member 21 or the sliding member to drive the sealing member 21 away from the mounting portion.

[0072] The second driving mechanism 40 comprises:

[0073] A rotating member 41 is rotatably connected to the main shaft 12 and is used to install the sliding assembly 32;

[0074] A second motor is arranged on one side of the main shaft 12;

[0075] The second transmission assembly 42 connects the first motor and the rotating member 41 .

[0076] In this embodiment, the sliding assembly 32 can be directly connected to the main shaft 12 for rotation, or a rotating member 41 connected to the main shaft 12 for rotation can be set, and the sliding assembly 32 is set on the rotating member 41 to achieve an indirect connection between the sliding assembly 32 and the main shaft 12, and the sliding assembly 32 can rotate relative to the main shaft 12.

[0077] In this embodiment, the rotating member 41 is arranged in a sleeve shape, and the rotating member 41 is connected to the main shaft 12 through a bearing. The sliding assembly 32 includes a mounting seat 32a fixedly arranged on the rotating member 41, and two guide holes are arranged on the mounting seat 32a. The sliding member includes a guide column slidably connected to the guide hole, and a mounting member 32c arranged at both ends of the guide column for connecting the two guide columns. The sealing member 21 is arranged on one of the mounting members 32c. The elastic member is preferably a compression spring set on the outer periphery of the guide column, one end of the compression spring abuts against the mounting seat 32a, and the other end abuts against the mounting member 32c where the sealing member 21 is not arranged. Alternatively, a tension spring can be arranged between the mounting seat 32a and the mounting member 32c where the sealing member 21 is arranged, and the tension spring and the compression spring make the sealing member 21 abut against the outer periphery of the mold. The first driving member 33 is preferably arranged in the first cylinder on one side of the rotating member 41 and the rotating shaft. The push rod of the first cylinder is arranged toward the mounting member 32c where the sealing member 21 is not arranged. The push rod of the first cylinder extends to push the mounting member 32c to slide, so that the sealing member 21 is away from the mold.

[0078] In this embodiment, the mold is arranged in a round pancake shape. Theoretically, the mold is arranged coaxially with the main shaft 12. Specifically, the mold can be positioned before loading so that the mold is coaxial when placed on the suction cup 11. However, when there is a certain eccentricity between the main shaft 12 and the mold, or when the outer periphery of the mold is not a regular circle, the sliding assembly 32 and the elastic member will allow the sealing member 21 to abut against the mold, and there is still a certain error tolerance.

[0079] In this embodiment, the second drive mechanism 40 and the third drive mechanism 50 are both driven by pulleys, the second motor and the third motor are arranged side by side, a synchronous wheel is arranged at the end of the main shaft 12 away from the suction cup 11, and another synchronous wheel is arranged on the rotating member 41. The two synchronous wheels are arranged coaxially.

[0080] In addition, when tearing the tape, the sealing member 21 is driven away from the mold by the first driving mechanism 30, so that the tape can be torn off to expose the injection port. After the injection is completed, the first driving mechanism 30 drives the sealing member 21 to abut against the outer periphery of the mold, and the second driving mechanism 40 drives the sealing member 21 to rotate around the outer periphery of the mold, driving the tape to stick back to the outer periphery of the mold, thereby avoiding resin overflow caused by the rotation of the injection port.

[0081] In another embodiment of the present invention, referring to Figures 1 to 7 The automatic glue injection device also includes a centering mechanism 60 arranged on one side of the clamp mechanism 10, which is used to align the mold with the clamp mechanism 10, and a loading mechanism 70 arranged on the side of the centering mechanism 60 away from the clamp mechanism 10; the loading mechanism 70 is used to place the mold into the centering mechanism 60 and the clamp mechanism 10 in sequence.

[0082] In this embodiment, the centering mechanism 60 can be selected from two centering cylinders arranged opposite to each other, and two positioning blocks with V-shaped notches are respectively arranged at the free ends of the push rods of the two centering cylinders. The two centering cylinders extend out of the two V-shaped notches at the same time and move toward each other to clamp the mold. It is worth noting that when the positioning blocks clamp the mold, the push rods of the two centering cylinders are fully pushed out, and the mold is coaxial with the main shaft 12.

[0083] In this embodiment, the feeding mechanism 70 includes a feeding cylinder and a rotating cylinder whose rotating end is connected to the cylinder body of the feeding cylinder. The rotating cylinder drives the feeding cylinder to rotate and makes the push rod of the feeding cylinder face downward. The push rod of the feeding cylinder is provided with a suction plate for docking with the mold on the conveyor belt below. After the feeding cylinder completes the feeding, the rotating cylinder drives the feeding cylinder to rotate 90 degrees or 270 degrees so that the mold faces the centering mechanism 60.

[0084] In some embodiments, reference Figures 1 to 7 , the centering mechanism 60 comprises:

[0085] A centering clamp 61, used for grabbing the mold;

[0086] A fourth driving mechanism 62, used for driving the centering jaws 61 to open and close;

[0087] The seventh driving mechanism 63 is used to drive the mold on the centering clamp 61 to dock with the clamp mechanism 10. In this embodiment, the fourth driving mechanism 62 includes a mounting plate, a screw rod rotatably arranged above the mounting plate, two nut pairs arranged on the screw rod, and a fourth motor driving the screw rod to rotate. The lower end of the nut pair is slidably connected to the mounting plate. The screw rod includes two left and right sections, and the threads on the two sections are arranged in opposite directions. When the screw rod rotates, the two nut pairs move toward or away from each other. The centering clamp 61 includes positioning blocks respectively arranged on the two nut pairs, and the positioning blocks are provided with V-shaped notches. The V-shaped notches of the two positioning blocks are opposite to each other to clamp the mold. The seventh driving mechanism 63 includes an electric cylinder arranged below the mounting plate, the moving end of the electric cylinder is connected to the mounting plate, and the moving direction of the electric cylinder is parallel to the main shaft 12. By arranging the centering clamp 61, the fourth driving mechanism 62 and the seventh driving mechanism 63, the mold and the main shaft 12 are kept in a coaxial state.

[0088] In some embodiments, reference Figures 1 to 7 The automatic glue injection device further includes a glue peeling mechanism 80, and the glue peeling mechanism 80 includes:

[0089] The adhesive tearing jaw 81 is used to grab the adhesive head of the adhesive tape;

[0090] A fifth driving mechanism 82, used for driving the glue peeling jaw 81 to move closer to or away from the mold;

[0091] The glue head finding sensor is arranged on the glue tearing jaw 81 .

[0092] The automatic glue injection device further includes a mouth-finding mechanism 90, and the mouth-finding mechanism 90 includes:

[0093] Mouth-finding sensor 91;

[0094] The sixth driving mechanism 92 is used to drive the mouth-finding sensor to move closer to or away from the mold.

[0095] The glue peeling jaw 81 may be a pneumatic finger. In this embodiment, the glue peeling jaw 81 includes a mounting block 81a and a telescopic block 81b that are relatively arranged, and a clamping cylinder 81c that drives the telescopic block to dock with the mounting block 81a. The glue head sensor is arranged on the mounting block 81a or the telescopic block 81b. The glue peeling jaw 81 is preferably arranged above the suction cup 11, and the fifth driving mechanism 82 is preferably an electric cylinder. The mouth-finding mechanism 90 is arranged opposite to the glue peeling mechanism 80. The glue head sensor and the mouth-finding sensor 91 both use photoelectric sensors, and the sixth driving mechanism 92 is preferably a cylinder. The cylinder drives the mouth-finding sensor 91 to move to the top of the mold, and at the same time, the fifth driving mechanism 82 drives the glue-tearing jaw 81 to move to the top of the mold, and the third driving mechanism 50 drives the mold to rotate. When the tape head rotates to between the mounting block 81a and the telescopic block 81b, the glue-finding sensor detects the tape head, and the third driving mechanism 50 stops, and the glue-tearing jaw 81 clamps the tape head. Then the fifth driving mechanism 82 drives the glue-tearing jaw 81 away from the mold, and at the same time, the suction cup 11 and the mold rotate in coordination to tear the tape. When the glue injection port is exposed and rotates to the bottom of the mouth-finding sensor 91 and is detected, the mold stops, the mouth-finding mechanism 90 withdraws, and the upper glue injection nozzle 101 and the glue suction tube 102 synchronously descend to the glue filling port for glue filling. The lower end of the glue suction tube 102 is flush with the glue injection port, which is used to absorb the overflowed glue. After the glue injection is completed, the glue injection nozzle 101 and the glue suction tube 102 go up. The sealing member 21 is close to the outer peripheral wall of the mold and rotates along the outer peripheral wall. The glue tearing mechanism 80 replaces the tape and seals the glue injection port to prevent glue overflow caused by the rotation of the mold.

[0096] The present invention also proposes an automatic glue injection process, referring to Figures 1 to 7 , including the following steps:

[0097] Align the mold with the fixture mechanism 10 so that the center axis of the mold is coaxial with the rotation center of the fixture mechanism 10; in this step, the mold can be picked up from the conveyor belt by the robot and installed on the fixture mechanism 10. First, the coordinate values ​​of the robot and the fixture mechanism 10 are calculated according to their relative positions, and then the coordinate values ​​of the target mold on the conveyor belt are obtained by visual positioning. When the robot clamps the mold on the fixture mechanism 10, automatic centering is completed, so that the center axis of the mold is coaxial with the rotation center of the fixture mechanism 10.

[0098] The mold is clamped on the clamp mechanism 10, and the clamp mechanism 10 is driven to rotate to drive the mold to rotate; in this step, the clamp mechanism 10 includes a suction cup 11 docked with the mold and a main shaft 12 docked with the suction cup 11, and a negative pressure air path connected to the suction cup 11 is provided in the main shaft 12. The mold docks with the suction cup 11 and is clamped by the suction cup 11. The main shaft 12 is then driven to rotate by a motor. The motor and the main shaft 12 can be connected through a coupling. The two can also adopt a transmission method such as a pulley drive, a gear drive, and a sprocket drive. By rotating the mold, the tape head can be found later.

[0099] Detect the tape head of the tape on the outer periphery of the mold, and clamp the tape head to tear the tape to expose the glue injection port; in this step, a moving module or a swinging module can be set on one side of the clamp mechanism 10 to drive the glue tearing jaw 81 to approach or move away from the outer peripheral wall of the mold. The glue tearing jaw 81 is provided with a sensor to detect the tape head, which is named as the glue head finding sensor. When the mold rotates so that the tape head moves and enters the glue tearing jaw 81, the mold stops, the glue tearing jaw 81 clamps the tape head, and is driven away from the mold by the moving module or the swinging module, and the mold rotates again. At this time, the tape is torn to a certain length until the glue injection port is exposed.

[0100] The port-finding sensor 91 is driven to move to the top of the mold. After the port-finding sensor 91 detects the injection port, the clamp mechanism 10 and the mold are controlled to stop rotating. In this step, before the adhesive tape is torn off, the port-finding sensor 91 can be moved to the top of the mold by another moving module or swinging module, and its detection direction is set downward. When the adhesive is torn off, the injection port on the mold rotates together. When the injection port moves to the bottom of the port-finding sensor 91, the port-finding sensor 91 detects that the injection port moves to the set position, the mold stops rotating, and then the port-finding sensor 91 moves away from the injection port to make room for the injection area.

[0101] The glue injection nozzle 101 is driven to align with the glue injection port, and glue is injected into the mold; in this step, the glue injection nozzle 101 enters the glue injection area, and the glue injection nozzle 101 is aligned with the glue injection port, and the glue injection amount is controlled by the glue injection valve to achieve glue injection into the mold. In addition, a glue suction tube 102 can be set on one side of the glue injection nozzle 101 to absorb excess resin. After the glue injection is completed, the glue injection nozzle 101 is away from the mold to make room for the sealing member 21 to move.

[0102] The sealing member 21 is driven to approach the mold and press on the tape, and the sealing member 21 is driven to rotate around the periphery of the mold so that the tape is adhered to the periphery of the mold and the injection port is sealed. In this embodiment, the sealing member 21 is driven by the cylinder to approach and abut the mold, and then the sealing member 21 is driven to rotate around the periphery of the mold so that the torn tape is adhered to the peripheral wall of the mold. When the sealing member 21 rotates, the glue tearing jaw 81 moves toward the mold to return the tape.

[0103] Completing the above steps means that the mold has been automatically loaded, glued, injected, and sealed without the need for manual alignment. The method is also suitable for resins with higher fluidity. Compared with the original method of using resins with lower fluidity and sealing by rotating the mold, the automatic glue injection device and automatic glue injection process in the present invention have a wider range of applications.

[0104] The above description is only a partial or preferred embodiment of the present invention. Neither the text nor the drawings can limit the scope of protection of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the overall concept of the present invention, or direct / indirect application in other related technical fields are included in the scope of protection of the present invention.
