Description

Technical Field

[0001] The invention relates to the technical field of terminal injection molding processing, in particular to a feeding mechanism for terminal injection molding processing. Background Art

[0002] The terminal is a component that connects the external conductor to the battery. At the same time, the terminal can not only connect the circuit well, but also provide good power protection for electrical equipment. At present, a feeding mechanism is needed when the terminal is injection molded. The feeding device can be used to load the semi-finished terminal and the finished terminal can be transported and unloaded, thereby replacing the traditional manual loading and improving the efficiency of the terminal injection molding process;

[0003] The patent name disclosed in the prior art with application number "CN201910475242.9" is "A terminal embedding and removal device", which discloses that the terminal is placed on a terminal tray on one side of the terminal carrier. After installation, the first laser detection head senses the terminal, the turntable rotates, the terminal tray with the terminal is located on one side of the manipulator, the manipulator clamps the terminal, the terminal tray without the terminal rotates to the original position, and re-loads the material. The manipulator clamps the terminal and places it in the mold, and then performs injection molding in the injection molding mechanism. After the injection molding is completed, the manipulator clamps the terminal to the second laser detection head, and the second laser detection head detects the product. The manipulator includes a base fixed on the workbench, and a rotating rod is connected to the base through a universal ball. The rotating rod is connected to a clamping claw. Through the universal ball, the rotating rod can rotate at all angles to meet the clamping requirements;

[0004] The patent name disclosed in the prior art with application number "CN201921301533.8" is "A fully automatic feeding device for L-shaped special-shaped terminals", which discloses that the first positioning hole can cooperate with the first positioning column on the fixture body and the second positioning column on the injection mold. When using the feeding device, the feeding tray of the feeding tray feeding mechanism rotates to feed the terminal strip wrapped on the feeding tray and transmit it to the bending and cutting mechanism. The bending and cutting mechanism bends the terminal strip 90° into an L shape and then cuts it according to the set length of the terminal to form an L-shaped terminal. The conveying mechanism transports the cut terminals to the top of the carrier module and inserts the terminals into In the terminal slot of the terminal limit block of the carrier module, the six-axis manipulator clamps the carrier module with the terminal inserted by the fixture body. At this time, the first positioning column is inserted into the first positioning hole from one end of the positioning sleeve, and the carrier module is transferred to the injection mold, so that the second positioning column is inserted into the first positioning hole from the other end of the positioning sleeve to achieve positioning on the carrier body and the injection mold, and then the terminal in the terminal slot is pushed into the injection mold for injection molding to obtain a terminal injection molded product. Since the terminal slides in the terminal slot, the terminal slot can play a role in guiding the terminal to be inserted into the injection mold. The terminal cannot be deformed due to the limitation of the terminal slot, thereby improving the qualified rate of the terminal injection molded product;

[0005] When the feeding mechanism in the above prior art is used, the cut terminals are transported to the top of the carrier module through the transport mechanism, so as to facilitate the insertion of the terminals into the terminal slots of the terminal limit blocks of the carrier module at a later stage. However, since the structure of the transport mechanism is relatively simple, if a collision occurs during the transport process, the semi-finished terminals will fall, thereby affecting the later feeding operation.

[0006] Therefore, we propose a feeding mechanism for terminal injection molding to solve the above-mentioned problems. Summary of the invention

[0052] Embodiment 1: The feeding mechanism for terminal injection molding in this embodiment can improve the stability of the semi-finished terminal feeding process and prevent the semi-finished terminal from falling, thereby improving the production capacity and work efficiency.

The terminal material picking and pressing mechanisms 2 include a pressing plate 9 and a material picking plate 10. The upper parts of the front and rear sides of the material picking plate 10 are connected to the first support plate 7 through vertical plates 12. A pressing plate 9 is arranged above the material picking plate 10, and a terminal pressing cylinder 3 is installed through the upper surface of the first support plate 7. The lower end of the terminal pressing cylinder 3 is connected to the pressing cylinder 3. The upper surfaces of the clamping plates 9 are connected, and a terminal adsorption mechanism 15 made of a magnet block is installed in an internal groove on the side edge of the bottom surface of the feeding plate 10. A second support plate 8 is installed on the right side of the first support plate 7, and two groups of finished product feeding mechanisms 5 and a sprue head feeding mechanism 6 are installed below the second support plate 8. Each group consists of two finished product feeding mechanisms 5 and one sprue head feeding mechanism 6. The finished product feeding mechanisms 5 are arranged on the left and right sides of the sprue head feeding mechanism 6. An auxiliary block 14 is installed in an internal groove on the bottom surface of the feeding plate 10, and a regulating component for adjusting the rotation angle of the auxiliary block 14 is sleeved on the outer side of the four groups of terminal feeding and pressing mechanisms 2.

[0053] The bottom surface of the feeding plate 10 is provided with a feeding slot 101 for placing the semi-finished terminal. The lowest point of the rear side of the feeding plate 10 is higher than the lowest point of the front side of the feeding plate 10. A pressing block 91 and eight pressing columns 92 are installed on the bottom surface of the pressing plate 9. The pressing block 91 is arranged on the front side of the pressing column 92 in the middle position. The lower ends of the pressing block 91 and the pressing column 92 both penetrate the interior of the feeding plate 10. The pressing block 91 and the pressing column 92 form a lifting structure through the pressing plate 9. The auxiliary block One side of 14 is connected to the feeding plate 10 through a return spring 141, a rotating rod 13 is installed inside the auxiliary block 14, and the bottom end of the auxiliary block 14 passes through the inside of the feeding plate 10. A discharge trough 101 is correspondingly arranged below the pressing block 91, the pressing column 92 and the auxiliary block 14. After the pressing block 91 and the pressing column 92 are lowered, they are inserted into the discharge trough 101, and the lower end of the auxiliary block 14 is arranged in the discharge trough 101. The auxiliary block 14 forms a rotating structure through the rotating rod 13.

[0054] First, the entire feeding mechanism is connected to an external manipulator through a quick switching connector 1, and then the manipulator can control the entire feeding mechanism to move in multiple directions. When the feeding mechanism moves to the top of the semi-finished terminal, the manipulator drives the entire feeding mechanism to move downward. At this time, the terminal picking and pressing mechanism 2 drives the picking plate 10 to move downward. At this time, the semi-finished terminal enters the discharge groove 101 on the bottom surface of the picking plate 10. At this time, the side of the semi-finished terminal first applies an outward thrust to the auxiliary block 14, so that the auxiliary block 14 rotates with the rotating rod 13 as the center of the circle. At this time, the reset spring 141 is pulled and stored. When the semi-finished terminal is completely in After entering the discharge trough 101, the auxiliary block 14 will apply a squeezing force to the side of the semi-finished terminal through the stored force of the return spring 141, so that the auxiliary block 14 squeezes and clamps the semi-finished terminal. At the same time, the terminal adsorption mechanism 15 in the picking plate 10 applies an adsorption force to the semi-finished terminal. The terminal adsorption mechanism 15 is made of a magnet block, so the terminal adsorption mechanism 15 adsorbs the semi-finished terminal. Therefore, the coordinated use of the terminal adsorption mechanism 15 and the auxiliary block 14 can prevent the semi-finished terminal from falling during the loading and transportation process, thereby ensuring that the picking plate 10 can stably load and transport the semi-finished terminals.

[0055] Then, the entire loading mechanism is driven to move by the manipulator, so that the manipulator drives the material picking plate 10 to move the semi-finished terminal to the top of the injection mold. At this time, the manipulator drives the material picking plate 10 to descend again. At the same time, the terminal pressing cylinder 3 is started, and the output end of the terminal pressing cylinder 3 drives the pressing plate 9 to move downward, and then the pressing plate 9 drives the pressing block 91 below and the multiple groups of pressing columns 92 distributed at different positions to move downward together. At this time, the lower ends of the pressing blocks 91 and the pressing columns 92 penetrate the surface of the material picking plate 10 and then insert into the discharge trough 101, and then the pressing blocks 91 and the pressing columns 92 continue to descend to apply a downward thrust to the semi-finished terminals in the discharge trough 101, so that the semi-finished terminals are separated from the discharge trough 101, and then the pressing blocks 91 and the pressing columns 92 push and press the semi-finished terminals to a specific position in the injection mold, so that the semi-finished terminals are well embedded in the pre-set position in the injection mold, and then the material can be injected into the injection mold, and then the injection molding process can be carried out.

[0056] After the injection molding process is completed, the finished terminal is in the injection mold. Then the manipulator is started again, so that the manipulator drives the feeding mechanism to move. At this time, the finished product picking mechanism 5 and the sprue head picking mechanism 6 are directly above the injection mold. Then the finished terminal and the sprue head are picked up by the finished product picking mechanism 5 and the sprue head picking mechanism 6. In this way, the entire feeding mechanism can well transport and load the semi-finished terminals, as well as transport and unload the finished terminals, thereby replacing the traditional manual loading and improving the efficiency of the terminal injection molding process.

[0057] When it is necessary to switch the terminal picking and pressing mechanism 2, the motor in the manipulator can drive the quick switching connector 1 to rotate, and the quick switching connector 1 drives the first support plate 7 to rotate, so that the multiple terminal picking and pressing mechanisms 2 under the first support plate 7 can be switched to meet different usage requirements.

[0058] Embodiment 2: The feeding mechanism for terminal injection molding in this embodiment can ensure the stability of the semi-finished terminal feeding and avoid scratches on the surface of the semi-finished terminal, thereby ensuring the quality of the semi-finished terminal. For the specific structure, refer to the attached Figure 6-Figure 8 As shown, on the basis of Example 1, the regulating component includes a regulating frame 11, and the outer sides of the four groups of feeding plates 10 below the first support plate 7 are sleeved with a regulating frame 11 in a "U" shape, and a connecting rope 111 is installed below the regulating frame 11; a connecting block 112 in a "7" shape is installed above the regulating frame 11, and electric push rods 121 are installed in grooves on the outer side surfaces of the vertical plates 12 below the left and right sides of the first support plate 7, and the upper end of the connecting block 112 is slidably connected in the groove opened on the outer side surface of the vertical plate 12, and the lower end of the electric push rod 121 is connected to the upper surface of the connecting block 112, one end of the rotating rod 13 passes through the outer side surface of the feeding plate 10, and the outer end of the rotating rod 13 is wrapped with the connecting rope 111, and the rotating rod 13 forms a rotating structure through the regulating frame 11.

[0059] When the semi-finished terminal enters the discharge trough 101 in the bottom surface of the feeding plate 10, the electric push rod 121 in the outer vertical plate 12 is started at the same time, and the output end of the electric push rod 121 drives the connecting block 112 to move upward, and then the connecting block 112 drives the regulating frame 11 to move upward, and the regulating frame 11 in the shape of a "U" will simultaneously pull the upper ends of the multiple groups of connecting ropes 111 below, and then the multiple groups of pulled connecting ropes 111 will drive the multiple groups of rotating rods 13 to rotate, and the rotating rod 13 drives the outer auxiliary block 14 to rotate outward, and the reset spring 141 is pulled and stored, and the auxiliary block 14 is automatically rotated outward, so that the semi-finished terminal enters the discharge trough 101 in the bottom surface of the feeding plate 10. Inside, the auxiliary block 14 will not contact the side of the semi-finished terminal, thereby not causing scratches on the side of the semi-finished terminal, thereby protecting the semi-finished terminal well. When the semi-finished terminal enters the discharge trough 101 on the bottom surface of the material picking plate 10, the electric push rod 121 is started as described above, and the output end of the electric push rod 121 drives the connecting block 112 to move downward, and then the connecting block 112 drives the regulating frame 11 to move downward and reset. At this time, the auxiliary block 14 is reset by the reverse rotation of the reset spring 141, thereby making one side of the auxiliary block 14 closely fit and contact with the outer side of the semi-finished terminal, so that multiple groups of auxiliary blocks 14 cooperate with each other to clamp and fix the semi-finished terminal well.

[0060] Embodiment 3: The feeding mechanism for terminal injection molding in this embodiment can reduce the resistance of the pressing column 92 when applying a downward pressing force to the semi-finished terminal when pressing the semi-finished terminal, so as to facilitate the terminal material taking and pressing mechanism 2 to perform the material taking and pressing operation well. For the specific structure, refer to the attached Figure 9-12As shown, on the basis of Example 1, one side of the pressing column 92 in the middle position of the pressing plate 9 is connected to the control rope 152, and the other end of the control rope 152 is connected to one side of the terminal adsorption mechanism 15. A connecting spring 151 is installed on the side of the terminal adsorption mechanism 15 close to the feeding plate 10, and one end of the connecting spring 151 is connected to the inside of the feeding plate 10. The terminal adsorption mechanism 15 is arranged in a "T" shape. The terminal adsorption mechanism 15 forms a sliding structure with the feeding plate 10 through the control rope 152. When the output end of the terminal pressing cylinder 3 drives the pressing plate 9 to move downward, the pressing plate 9 drives the pressing block 91 below and the multiple groups of pressing columns 92 distributed at different positions to move downward together. At this time, the lower ends of the pressing block 91 and the pressing column 92 penetrate the feeding plate 10 surface is then inserted into the discharge trough 101, and then the pressing block 91 and the pressing column 92 continue to descend to apply a downward thrust to the semi-finished terminal in the discharge trough 101, and at the same time one of the pressing columns 92 will pull one end of the control rope 152, and at this time the other end of the control rope 152 pulls the terminal adsorption mechanism 15, so that the terminal adsorption mechanism 15 can enter the groove in the feeding plate 10, so that the terminal adsorption mechanism 15 is away from the semi-finished terminal under the feeding plate 10, thereby reducing the adsorption force of the terminal adsorption mechanism 15 on the semi-finished terminal, so that the pressing block 91 and the pressing column 92 can well push and press the semi-finished terminal to a specific position in the injection mold, so that the semi-finished terminal can be well separated from the discharge trough 101, thereby completing a series of tasks.
