[0039] This embodiment provides an automatic shell insertion mechanism, such as Figure 1-8 As shown, the automatic shell insertion mechanism includes a shell conveying component 1, a core conveying component 2, a guide mold component 3 and a pre-pressing component 4. The shell conveying component 1 is used to convey the shell 5 to the guide mold component 3, and the core conveying component 2 is used to convey the core 6 to the shell 5 at the guide mold component 3. The pre-pressing component 4 is located above the guide mold component 3, and it can move up and down to achieve the cooperation between the core 6 and the shell 5.

[0040] Specifically, first, the empty shell 5 is placed on the shell conveying assembly 1. After starting the shell conveying assembly 1, the shell 5 can be moved to the guide mold assembly 3; at the same time, the core 6 is also moved to the guide mold assembly 3 under the action of the core conveying assembly 2, and cooperates with the shell 5 at the guide mold assembly 3, and then the pre-pressing assembly 4 works to apply a downward force on the core 6 to achieve the compression of the core 6 and the shell 5.

[0041] This embodiment realizes automatic matching of the core 6 and the shell 5 through the cooperation of the shell conveying component 1, the core conveying component 2, the guide mold component 3 and the pre-pressing component 4. Compared with the traditional manual shell insertion method, this embodiment significantly reduces labor costs and improves work efficiency.

[0042] Of course, in order to achieve the coordination of the shell conveying assembly 1, the core conveying assembly 2, the guide mold assembly 3 and the pre-pressing assembly 4, the present embodiment also includes a bracket assembly 8. For example, a first support plate is provided under the shell conveying assembly 1, which is used to provide support for the shell conveying assembly 1; a second support plate is provided under the core conveying assembly 2, which is used to provide support for the core conveying assembly 2, and the pre-pressing assembly 4 is arranged directly above the guide mold assembly 3 through a third support plate.

[0043] In a specific embodiment, the shell conveying assembly 1 includes a transmission belt unit 11, a material blocking unit 12, a shell clamp unit 13, a mobile unit 14 and a fixed plate 15, wherein the fixed plate 15 and the transmission belt unit 11 are in the same horizontal plane, the material blocking unit 12 is arranged at the end of the transmission belt unit 11, and it can move so that the output end of the transmission belt unit 11 is connected or disconnected with the fixed plate 15, the shell clamp unit 13 is located above the mobile unit 14, and it can follow the mobile unit 14 to move along the fixed plate 15; the shell clamp unit 13 moves to clamp the shell 5 at the end of the transmission belt unit 11 and move it to the guide mold assembly 3.

[0044] Specifically, the transmission belt unit 11 is used to realize the loading of the shell 5; the material blocking unit 12 is used to move the shell 5 to the corresponding position one by one to avoid multiple shells 5 being crowded in the same position at the same time and causing mechanism failure; the shell clamp unit 13 is used to realize the clamping of the shell 5 and move it to the corresponding position; the moving unit 14 is used to provide driving force for the shell clamp unit 13 so that it can move horizontally along the fixed plate 15.

[0045] In this embodiment, when the shell 5 moves to the output end of the transmission belt unit 11, the moving unit 14 works, which drives the shell clamp unit 13 to move so that it clamps the shell at the output end of the transmission belt unit 11, and then the moving unit 14 continues to drive the shell clamp unit 13 to move so that it moves to the guide mold assembly 3.

[0046] In a specific embodiment, the shell conveying assembly 1 further comprises a shell correction position 16 , and along the moving direction of the shell 5 , the shell correction position 16 is located between the guide mold assembly 3 and the end of the transmission belt unit 11 .

[0047] The setting of the shell correction position 16 can avoid the movement distance being too long so that the various parts of the mechanism cause interference and affect the shell insertion quality.

[0048] In a specific embodiment, the transmission belt unit 11 includes a storage belt 111, a discharge belt 112, a first guide plate 113 and a second guide plate 114, the first guide plate 113 and the second guide plate 114 are arranged on the storage belt 111, and the first guide plate 113 and the second guide plate 114 are inclined so that one end of the two forms a larger space for storing the shell 5, and the other end forms a smaller space for allowing a single shell 5 to transition to the discharge belt 112.

[0049] Specifically, the storage belt 111 is mainly used to store multiple shells 5, and the unloading belt 112 is mainly used to realize the conveyance of a single shell 5, so the width of the storage belt 111 is greater than the unloading belt 112. In order to avoid problems with the arrangement of the shells 5 at the unloading belt 112, the width of the unloading belt 112 should be slightly greater than the outer diameter of one shell 5.

[0050] More specifically, the first guide plate 113 and the second guide plate 114 are both vertically arranged on the storage belt 111, but they do not move with the storage belt 111. The first guide plate 113 and the second guide plate 114 are inclined to form a V-shaped structure, in which the side with a larger opening faces the end of the storage belt 111 away from the unloading belt 112, and the other side of the structure has a smaller opening facing the unloading belt 112; in this way, after a plurality of shells 5 are gathered on the side with the larger opening, individual shells 5 can be moved one by one to the unloading belt 112 through the smaller opening.

[0051] In addition, in order to better match the outer diameter of the shell 5, or to match a shell 5 with a different outer diameter, a cylinder is provided on the second guide plate 114 near the unloading belt 112, which acts on the second guide plate 114 to adjust the size of the smaller opening on the other side of the V-shaped structure.

[0052] In a specific embodiment, the shell clamp unit 13 includes a first clamp 131, a second clamp 132 and a third clamp 133 which are horizontally arranged in parallel, and the first clamp 131, the second clamp 132 and the third clamp 133 are all connected to the driving member, the first clamp 131 is used to move the shell 5 from the end of the transmission belt unit 11 to the shell correction position 16, the second clamp 132 is used to move the shell from the shell correction position 16 to the guide mold assembly 3, and the third clamp 133 is used to move the core 6 and the shell 5 assembled at the guide mold assembly 3 to the discharge position 7.

[0053] Specifically, the shell conveying assembly 1 provided in this embodiment has four corresponding fixed positions during the process of conveying the shell, the first position is the end of the unloading belt 112, the second position is the shell correction position 16, the third position is directly below the guide mold assembly 3, and the fourth position is the discharge position 7. Among them, the first position, the second position and the third position are set on the fixed plate 15, and the fourth position is located on the discharge plate at the end of the fixed plate 15.

[0054] The housing clamp unit 13 includes a first clamp 131 , a second clamp 132 and a third clamp 133 which are arranged horizontally and in parallel. The first clamp 131 , the second clamp 132 and the third clamp 133 are driven by a driving member to achieve simultaneous actions.

[0055] The above four fixed positions and three fixtures correspond to two states:

[0056] The first state is to clamp an empty shell 5, specifically: when the first shell 5 moves to the end of the unloading belt 112, the shell clamp unit 13 is actuated, at which time the first clamp 131 corresponds to the end of the unloading belt 112, the second clamp 132 corresponds to the shell correction position 16, and the third clamp 133 is located directly below the guide mold assembly 3;

[0057] The second state is that the shell 5 and the core 6 are matched and then discharged. Specifically, the first clamp 131 corresponds to the shell correction position 16, the second clamp 132 is located directly below the guide mold assembly 3, and the third clamp 133 is located at the discharge position 7;

[0058] The first state and the second state are cycled alternately, so that the shell 5 and the core 6 are matched one by one and transported to the discharge position 7 one by one.

[0059] The moving unit 14 includes a track. The first clamp 131, the second clamp 132 and the third clamp 133 are arranged together on a slide, and the slide matches the track and can slide along the track. More specifically, the moving unit 14 and the shell clamp unit 13 are composed of a slide cylinder plus three clamping claw cylinders and mechanical structural parts. The specific method is that the slide cylinder is installed on the equipment panel, a connecting plate is installed on the moving part of the slide cylinder, and the three clamping claw cylinders are fixed at a specified interval. When the slide cylinder moves, it drives the clamping claw cylinder to move synchronously, and then a clamp block is installed on the clamping claw cylinder, and a plate is fixed in the middle space between the clamp block and the cylinder, so that when the clamp releases the aluminum shell, the aluminum shell does not move on the plate, and the clamp moves the aluminum shell once each time. The above three clamping claw cylinders correspond to the first clamp 131, the second clamp 132 and the third clamp 133.

[0060] In addition, the spacing between the first clamp 131 , the second clamp 132 and the third clamp 133 matches and corresponds to the spacing between the above four fixed positions.

[0061] In a specific embodiment, a detection component is provided at the material blocking unit 12 and / or the guiding mold assembly 3 for detecting whether there is a housing 5 at the material blocking unit 12 and / or the guiding mold assembly 3 .

[0062] More specifically, the detection member at the blocking unit 12 is a photoelectric sensor, which can detect whether the empty shell 5 is moved to the end of the unloading belt 112. When the shell 5 is detected, the moving unit 14 controls the shell clamp unit 13 to start working. The detection member at the guide mold assembly 3 can be a photoelectric sensor or a height sensor, which can detect whether there is a shell 5 at the guide mold assembly 3, because when there is a shell 5, the shell 5 will be higher than the guide mold assembly 3, and the height sensor will receive a signal.

[0063] In addition, there are many kinds of specific structures of the material blocking unit 12, for example: the material blocking unit 12 may include a cylinder with a baffle at the end of the cylinder. When the cylinder works, the baffle can be extended and retracted. When the baffle is extended, it can just block the end of the unloading belt 112 to prevent congestion caused by more shells 5 being conveyed to the fixed plate 15. When the baffle is retracted, the end of the unloading belt 112 is released, so that the shells 5 can be conveyed.

[0064] The shell conveying assembly 1 provided in this embodiment is mainly used to realize the loading of the shell 5. The specific loading process is: first, manually take out the empty shell 5 from the material tray and put it on the storage belt 111, start the transmission belt unit 11 to run the shell 5 to automatically arrange it on the unloading belt 112, and the unloading belt 112 continues to transport the shell 5 to the tail end of the belt. The stopper unit 12 is installed at the tail end of the belt. The detection photoelectric is installed at the position of the stopper unit 12. When the shell 5 is detected, the moving unit 14 moves forward to drive the shell clamp unit 13 to move forward, and the first clamp 131 Align the shell 5 with the position of the blocking unit 12. After it is in place, the shell clamp unit 13 starts to clamp the shell 5 while the blocking unit 12 retracts. Then the shell 5 moves to the shell correction position 16. At the same time, the blocking unit 12 extends to block the next shell 5. The unloading belt 112 continues to deliver the next shell 5 to the tail of the belt. The moving unit 14 moves forward to the position of the blocking unit 12 again, and the action cycle is followed to convey the shell 5 to the bottom of the guide mold assembly 3. After the shell 5 is in place, the guide mold assembly 3 is pressed down to insert the shell 5, and then stops to wait for the core 6 to be put in.

[0065] In a specific embodiment, the core conveying assembly 2 includes a material unloading unit 21, a material picking moving unit 22, a core clamp unit 23 and a material discharging moving unit 24. The material picking moving unit 22 is connected to the core clamp unit 23, and can drive the core clamp unit 23 to move to the material unloading unit 21 to clamp the core 6. The material discharging moving unit 24 can drive the core clamp unit 23 to move so that the clamped core 6 moves into the guide mold assembly 3 and cooperates with the outer shell 5 in the guide mold assembly 3.

[0066] Specifically, the unloading unit 21 is mainly used to store the core 6; the material taking and moving unit 22 is mainly used to drive the core clamp unit 23 to move; the core clamp unit 23 is used to clamp the core 6; the material unloading and moving unit 24 is used to place the core 6 clamped by the core clamp unit 23 into the guide mold assembly 3. When the core 6 is matched with the shell 5, the third clamp 133 can clamp it and place it at the discharge position 7.

[0067] In a specific embodiment, the core conveying assembly 2 also includes a material unloading lifting unit 25 and a rotating unit 26, and the material unloading lifting unit 25 and the rotating unit 26 are both connected to the core clamp unit 23. The material unloading lifting unit 25 and the rotating unit 26 can rotate the core clamp unit 23 90° and lift or lower it in the vertical direction.

[0068] The material unloading and lifting unit 25 has many structures. For example, the material unloading and lifting unit 25 may include a slide cylinder, and the core clamp unit 23 is connected to the slide cylinder, and the slide cylinder can drive the core clamp unit 23 to move. The rotating unit 26 may include a rotating cylinder, and the rotating cylinder acts on the core clamp unit 23 to drive the core clamp unit 23 to rotate.

[0069] Specifically, when the core clamp unit 23 is running, it waits for the material to be delivered by the unloading unit 21. After the material is delivered, the material taking moving unit 22 drives the core clamp unit 23 to move forward to the unloading mechanism for cross docking. After the core clamp unit 23 is in place, it clamps the core 6, and then the material taking moving unit 22 returns to the original path. After returning to the position, the unloading lifting unit 25 and the rotating unit 26 act at the same time to rotate the core clamp unit 23 90°, and the core clamp unit 23 is lifted as a whole by the unloading lifting unit 25 and exceeds the upper plane of the guide mold assembly 3 by about 5mm to ensure that the core 6 does not interfere with the bottom of the core when it moves over. After rising into place, the material discharging moving unit 24 extends out to move the core 6 clamped by the core clamp unit 23 to the top of the guide mold assembly 3, and then releases the core clamp unit 23, and the core 6 It naturally descends and falls into the bell mouth 33 of the guide mold body 31, and automatically falls into the shell 5 below. At the same time, the pre-pressing assembly 4 just above the guide mold assembly 3 is pressed down to press the core 6 completely into the shell 5, and then the core clamp unit 23 returns to the waiting state for picking up the material and waits for the next core 6, and the guide mold assembly 3 rises synchronously. The shell clamp unit 13 cycles once, and the first clamp 131 grabs an empty shell 5 at the end of the transmission belt unit 11 and moves it to the shell correction position 16. The second clamp 132 moves the shell 5 at the shell correction position 16 to the bottom of the guide mold assembly 3, and the third clamp 133 moves the shelled product to the shell entry and discharge position 7, realizing the entire process of automatic shell entry and waiting for the next core shell entry action, and the action runs in a cycle.

[0070] In one of the embodiments, the core conveying assembly 2 includes two slide cylinders, a 90° rotating cylinder and a clamping claw cylinder, which are used to clamp the parallel core 6 on the disc, rotate it 90° and move it to the guide mold assembly 3. The main working process of this structure is that the unloading unit 21 is installed on the equipment disc to fix the core 6. When the disc drives the core to the designated workstation, the front and rear cylinders of the material picking moving unit 22 extend to move the core clamp unit 23 to the capacitor core unloading mechanism and clamp the core 6, and then the front and rear cylinders of the material picking are retracted. Next, the rotating cylinder of the rotating unit 26 rotates 90° so that the core 6 is in a vertical state and in the same direction as the outer shell 5. Then the front and rear cylinders of the material unloading moving unit 24 extend. After extending into place, the core 6 is just above the guide mold assembly 3. The core clamp unit 23 is released, and the core 6 falls freely into the bell mouth 33 to realize the shell entry function.

[0071] More specifically, the material taking moving unit 22, the core clamp unit 23 and the material discharging moving unit 24 are similar in structure to the moving unit 14 and the shell clamp unit 13, and are all composed of a slide cylinder and a corresponding clamping claw cylinder.

[0072] In a specific embodiment, the guide mold assembly 3 includes a guide mold body 31, the lower end of the guide mold body 31 has a circular hole 32 with a chamfer, the inner diameter of the circular hole 32 matches the outer diameter of the shell 5, and the upper end of the guide mold body 31 has a bell mouth 33 for cooperating with the core 6.

[0073] In a specific embodiment, the guide mold assembly 3 further includes a bracket 34 , a slide cylinder is disposed on the bracket 34 , the guide mold body 31 is fixed on the slide cylinder, and the slide cylinder can drive the guide mold body 31 to move up and down.

[0074] Specifically, the main feature of the guide mold assembly 3 is that the lower end is a circular hole 32 with the diameter of the shell 5 and has a chamfer, and the upper end is a bell mouth 33. Its main function is to be in the third fixed position mentioned above. A bracket 34 is installed on the outside of this position, and a slide cylinder is vertically installed on the bracket 34 to fix the guide mold body 31 on the slide cylinder. When the shell 5 moves to this position, the slide cylinder drives the guide mold body 31 to descend, and the lower end of the guide mold body 31 is inserted into the upper port of the shell 5. The upper end of the guide mold body 31 has a bell mouth 33. The core 6 automatically falls into the shell 5 through the bell mouth 33, and then the pre-pressing assembly 4 is pressed down to ensure reliable entry into the shell.

[0075] In a specific embodiment, there are many specific structures of the pre-pressing assembly 4. For example, the pre-pressing assembly 4 includes a fixed plate 41, a telescopic cylinder 42 and a pre-pressing head 43. The fixed plate 41 is fixed on the bracket assembly 8, the telescopic cylinder 42 is arranged on the fixed plate 41, and the pre-pressing head 43 is arranged at the output end of the telescopic cylinder 42; in this way, when the telescopic cylinder 42 works, it can drive the pre-pressing head 43 to move up and down to achieve compression. In addition, the material of the pre-pressing head 43 is preferably an elastic material to avoid damage to the core 6 caused by the material being too hard during the process of compressing the core 6 and the shell 5.

[0076] The automatic shell insertion mechanism provided in this embodiment realizes the automation of shell insertion, reduces labor costs, and improves work efficiency; at the same time, the shell insertion is carried out in the guide mold assembly 3, which prevents the core surface from being scratched when the core is inserted into the shell.
