Description

Technical Field

[0001] This utility model relates to the technical field of LED base shell production, and in particular to a rapid feeding device for parts used in LED base shell injection molding. Background Technology

[0002] LED back covers are widely used in various LED display scenarios, such as outdoor advertising screens and commercial display screens. Currently, there are LED back covers made of plastic, which are injection molded by the interaction of a concave mold and a convex mold.

[0003] Due to varying requirements for LED base housings, different specifications necessitate the integrated injection molding of various components. For instance, integrating the nut as a component with the base housing facilitates assembly with other devices. Furthermore, when the base housing requires thin-walled microchannels, directly using plastic injection-molded microchannels would result in insufficient structural strength. Therefore, high-strength metal microchannels are selected for integrated injection molding to ensure that the structural strength and precision requirements of the base housing are met.

[0004] Existing feeding devices, such as the utility model with patent publication number CN215039662U, involve a nut fixture for an LED base shell. This fixture includes a fixed plate, a movable plate parallel to the fixed plate, and a driving component for moving the fixed plate and the movable plate closer together or further apart. The movable plate has several receiving tubes for holding nuts at its end away from the fixed plate. Each receiving tube has a storage channel along its axis, and its sidewall has a clamping member that abuts against the nuts. The fixed plate has a push rod that pushes out the nuts from the corresponding receiving tubes. In use, the nuts are placed in the receiving tubes, the nut fixture is aligned with the mold, and the driving component drives the push rod to push out the nuts, completing the nut feeding process.

[0005] However, with the existing feeding device, each injection molding of the bottom shell requires manual placement of the shells into the receiving tube, which is time-consuming and labor-intensive, affecting the production efficiency of the bottom shells. Utility Model Content

[0006] To address the problems of time-consuming and labor-intensive production processes that affect the efficiency of LED bottom shell production, this invention provides a rapid feeding device for injection-molded parts for LED bottom shells.

[0007] This utility model provides a rapid feeding device for LED bottom shell injection molding parts, which adopts the following technical solution:

[0008] A rapid feeding device for LED bottom shell injection molding parts includes a worktable, a material conveying component for guiding the parts to be arranged in a queue, a driving component for driving the parts to move along the queue forward direction, a base disposed on the worktable, a main slider slidably disposed on the base, a material blocking component for blocking the queue movement of the parts, and a feeding component for picking up materials from the material conveying component and feeding them into the injection mold. The main slider slides and engages with the base along the direction of the material conveying component toward or away from the injection mold. The material blocking component and the feeding component are both connected to the main slider.

[0009] The material conveying assembly includes a material conveying seat set on the workbench and a material conveying pipe connected to the material conveying seat. The material conveying seat has a discharge port that allows parts to pass through. The material conveying pipe is detachably connected to the material conveying seat and communicates with the discharge port. The end of the material conveying pipe away from the material conveying seat is the loading end.

[0010] By adopting the above technical solution, during feeding, the parts are loaded into the conveying assembly, arranging them in a queue. The main slider is driven to slide away from the injection mold along the conveying assembly, and the drive assembly moves the parts along the queue's forward direction, allowing the foremost part to enter the feeding assembly. The parts can then be removed from the conveying assembly via the feeding assembly. Alternatively, the main slider is driven to slide towards the injection mold along the conveying assembly, causing the parts in the blocking assembly to move in a queue. This allows the feeding assembly to bring the parts closer to the injection mold, and then feed them into the mold, thus achieving automatic feeding of the parts. When the number of parts remaining in the conveying pipe is low, parts can be added from the loading end to replenish the pipe without affecting equipment operation, thereby improving the production efficiency of the bottom shell.

[0011] Preferably, the material conveying pipe is provided with a guide section at the loading end, the guide section being constricted in shape, and the guide section gradually narrowing from near the loading end to near the discharge port.

[0012] By adopting the above technical solution, the guide unit helps to guide the components into the material conveying pipeline in a smoother manner.

[0013] Preferably, the material conveying pipe is further provided with an elongated groove, which is distributed along the length of the material conveying pipe and is connected to the inside of the material conveying pipe.

[0014] By adopting the above technical solution, the remaining condition of components inside the material conveying pipeline can be observed through the long trough.

[0015] Preferably, the driving assembly includes a connecting plate sleeved on the material conveying pipe, a connecting block detachably connected to the connecting plate, and a vibrating element for driving the connecting block to vibrate. The connecting block is sleeved on the material conveying pipe, the connecting plate is fixedly connected to the material conveying pipe, the connecting block is close to the loading end, and the vibrating end of the vibrating element abuts against the connecting block.

[0016] By adopting the above technical solution, when the drive component drives the parts, the vibration of the vibrating component drives the connecting block to vibrate, and the connecting block drives the vibration of multiple material conveying pipes, so that the parts in the multiple material conveying pipes can gradually move along the forward direction of the formation.

[0017] Preferably, the worktable is provided with a drive seat, and the drive seat is provided with a first drive component. The first drive component is used to drive the main slider to slide along the material conveying assembly toward or away from the injection mold. The drive end of the first drive component is connected to the main slider.

[0018] By adopting the above technical solution, during driving, the main slider can be easily driven to approach or move away from the injection mold through the first driving component.

[0019] Preferably, the baffle assembly includes a slide rod passing through the main slide, a drive plate slidably disposed on the main slide, and a pressure plate slidably disposed on the drive plate. The slide rod and the main slide slide in a direction of component alignment. One end of the slide rod is fixedly connected to the drive plate. A first reset guide is disposed between the pressure plate and the drive plate. The first reset guide includes a guide post disposed on the pressure plate, a limiting block disposed at one end of the guide post, and an elastic element connecting the pressure plate and the drive plate. One end of the guide post is fixedly connected to the pressure plate, and the end of the guide post facing away from the pressure plate passes through the drive plate. The limiting block is disposed at the end of the guide post facing away from the pressure plate, and the elastic element is sleeved on the guide post.

[0020] By adopting the above technical solution, the elastic force of the elastic element keeps the pressure plate abutting against the material conveyor seat, thereby preventing the movement of the parts. In addition, the elastic element helps to prevent the transmission of impacts and vibrations from the vibrating element.

[0021] Preferably, the feeding assembly includes a main clamping plate and a secondary clamping plate that are parallel to each other. The main clamping plate and the secondary clamping plate face each other along the direction of the component queuing. The main clamping plate is fixedly connected to the drive plate. A second reset guide is provided between the main clamping plate and the secondary clamping plate. A receiving groove is opened on the side of the secondary clamping plate away from the main clamping plate. The shape of the receiving groove is just enough to place a component. A ejector pin is provided on the main clamping plate. One end of the ejector pin is connected to the main clamping plate. The end of the ejector pin away from the main clamping plate passes through the secondary clamping plate and extends into the receiving groove. The ejector pin and the secondary clamping plate slide and cooperate along the direction of the component queuing.

[0022] When the main slider is driven to slide to the minimum distance along the material conveying assembly away from the injection mold, the receiving groove connects to the discharge port; when the main slider is driven to slide to the maximum distance along the material conveying assembly towards the injection mold, the pressure plate abuts against the material conveying seat and blocks the discharge port, and the receiving groove aligns with the component mounting position of the injection mold.

[0023] By adopting the above technical solution, when the main slide block is driven to slide to its minimum distance along the material conveying assembly away from the injection mold, the receiving groove connects to the discharge port. This allows the components within the material conveying pipe to move along the forward direction of the queue via a vibrating component, causing the foremost component to enter the receiving groove. When the main slide block is driven to slide to its maximum distance along the material conveying assembly towards the injection mold, the receiving groove aligns with the component mounting position on the injection mold. This allows the main clamping plate to move towards the secondary clamping plate, and the ejector pin pushes the component out of the receiving groove, thus positioning the component in the component mounting position on the injection mold.

[0024] Preferably, the second reset guide has the same structure as the first reset guide. One end of the guide post in the second reset guide is fixedly connected to the sub-clamping plate. The end of the guide post in the second reset guide that drives the guide post away from the pressure plate passes through the main clamping plate. The limiting block in the second reset guide is set at the end of the guide post that is away from the sub-clamping plate. One end of the elastic element in the second reset guide is connected to the main clamping plate, and the end of the elastic element that is away from the main clamping plate is connected to the sub-clamping plate.

[0025] By adopting the above technical solution, the elastic force of the elastic element in the second reset guide ensures that a certain distance is maintained between the sub-clamping plate and the main clamping plate in their natural state. Furthermore, the elastic element helps to further prevent the transmission of impacts and vibrations from the vibrating element.

[0026] Preferably, the main slider is provided with a drive frame, and the drive frame is provided with a second drive member. The second drive member is used to drive the main clamping plate to move in a direction close to or away from the secondary clamping plate, and the drive end of the second drive member is connected to the main clamping plate.

[0027] By adopting the above technical solution, the main clamping plate is moved by the second driving component, so that the secondary clamping plate extends into the injection mold, and the ejector pin pushes the parts in the receiving groove to the part mounting position of the injection mold.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] When there are few components left in the conveying pipe, components can be added from the loading end into the conveying pipe to replenish them at any time, so that the replenishment process does not affect the operation of the equipment, thereby improving the production efficiency of the bottom shell.

[0030] The elastic force of the elastic element in the first reset guide and the second reset guide helps to prevent the auxiliary clamping plate from being impacted and vibrated by the vibrating element. Attached Figure Description

[0041] The following will refer to the appendix in the embodiments of this utility model. Figures 1 to 8 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0042] A rapid feeding device for LED bottom shell injection molding parts, referring to Figure 1 It includes a rectangular worktable 1, a material conveying mechanism and a material loading mechanism. The material conveying mechanism is used to transport the parts 16 arranged in a row, and the material loading mechanism is used to take the parts 16 from the material conveying mechanism and load them into the injection mold.

[0043] In this embodiment, refer to Figure 2 and Figure 3 Component 16 is a nut, which is cylindrical in shape and has a threaded hole at one end. Component 16 needs to be installed into the cavity mold 12 of the injection mold. Specifically, the cavity mold 12 is cuboid in shape and is distributed along the height direction of the worktable 1, with one end of the cavity mold 12 closest to the worktable 1. The cavity mold 12 has a molding groove 13, which is rectangular in shape and corresponds to the LED bottom shell to be injected. The molding groove 13 has molding patterns that are adapted to the shape of the LED bottom shell.

[0044] In addition, refer to Figure 2 and Figure 3 The die 12 also has a mounting groove 14 for placing the component 16. The mounting groove 14 is circular in shape corresponding to the cross-section of the component 16 and serves as the mounting position for the component 16 in the injection mold. A core 15 is also provided on the die 12. The cores 15 are distributed along the axial direction of the mounting groove 14, and their distribution direction is the same as the width direction of the worktable 1. One end of the core 15 extends into the mounting groove 14, and the other end of the core 15 is used for screw hole fitting. Multiple mounting grooves 14 are provided according to the needs of the component 16, and multiple cores 15 are provided corresponding to the mounting grooves 14. Multiple cores 15 extend one-to-one from multiple mounting grooves 14. Thus, by fitting multiple components 16 one-to-one onto multiple cores 15 and performing injection molding through the cooperation of the punch and die 12, the required LED base shell can be obtained.

[0045] Specifically, refer to Figure 1 and Figure 4The material handling mechanism includes a material handling assembly 2 for guiding the parts 16 into a line arrangement and a drive assembly 3 for driving the parts 16 to move along the line forward direction. The loading mechanism is located in front of the line of parts 16. By placing the parts 16 in the material handling assembly 2, the parts 16 are arranged in a line within the material handling assembly 2. The drive assembly 3 drives the parts 16 along the line forward direction to the loading mechanism, which then removes the parts 16 from the material handling mechanism and loads them into the injection mold.

[0046] Among them, reference Figure 1 and Figure 4 The material conveying assembly 2 includes a material conveying seat 21 disposed on the workbench 1 and a material conveying pipe 22 connected to the material conveying seat 21. The material conveying seat 21 is rectangular in shape and is distributed along the height direction of the workbench 1, with the material conveying seat 21 located near one long side of the workbench 1. The material conveying seat 21 has a discharge port 23, which is circular and extends through the front and rear surfaces of the material conveying seat 21, allowing the parts 16 to pass through. The material conveying pipe 22 is a hollow circular pipe, distributed along the width of the workbench 1. The inner diameter of the material conveying pipe 22 is the same as the diameter of the discharge port 23. One end of the material conveying pipe 22 is bolted to the material conveying base 21, meaning the material conveying pipe 22 is detachably connected to the material conveying base 21 and communicates with the discharge port 23. The end of the material conveying pipe 22 away from the material conveying base 21 is the loading end 24. By loading the components 16 into the material conveying pipe 22 from the loading end 24, the components 16 inside the material conveying pipe 22 can be arranged in a row, and the direction of movement of the row along the material conveying pipe 22 towards the discharge port 23 is the direction of movement of the row. In this embodiment, a single material conveying pipe 22 can accommodate a maximum of 50 components 16 (nuts).

[0047] Continue to refer to Figure 1 and Figure 4 The material conveying pipe 22 has a guide section 25 at its loading end 24. The guide section 25 is tapered and gradually narrows from near the loading end 24 towards the discharge port 23, thus facilitating the smooth entry of the component 16 into the material conveying pipe 22. Furthermore, the material conveying pipe 22 is also provided with a long groove 26, which is distributed along the length of the material conveying pipe 22 and communicates with the inside of the material conveying pipe 22. The remaining status of the component 16 within the material conveying pipe 22 can be observed through the long groove 26.

[0048] Reference Figure 1 and Figure 4Multiple discharge ports 23 are provided corresponding to the number of mounting slots 14. The distribution of multiple discharge ports 23 to multiple mounting slots 14 is consistent, that is, the positional distribution of multiple discharge ports 23 is consistent with the positional distribution of multiple mounting slots 14. Multiple material conveying pipes 22 are provided corresponding to the number of discharge ports 23. Multiple material conveying pipes 22 are connected one-to-one to multiple discharge ports 23, so as to facilitate the simultaneous feeding of multiple required components 16 according to the current needs of the LED base shell.

[0049] During feeding, components 16 are loaded into the conveying pipe 22 from the loading end 24, causing the components 16 in the conveying pipe 22 to be arranged in a queue. Driven by the drive assembly 3, the components 16 in the conveying pipe 22 are moved along the forward direction of the queue, thus conveying the material to the feeding mechanism. In addition, when there are few components 16 remaining in the conveying pipe 22, components 16 can be loaded into the conveying pipe 22 from the loading end 24 at any time to replenish it, so that the replenishment process does not affect the operation of the equipment.

[0050] Specifically, refer to Figure 4 and Figure 5 The driving assembly 3 includes a connecting plate 31 sleeved on the material conveying pipe 22, a connecting block 32 detachably connected to the connecting plate 31, and a vibrating element 33 for driving the connecting block 32 to vibrate. The connecting plate 31 is circular and fixedly connected to the material conveying pipe 22. Multiple connecting plates 31 are provided corresponding to the number of material conveying pipes 22, and multiple connecting plates 31 are sleeved on multiple material conveying pipes 22 one by one. The connecting blocks 32 are rectangular and distributed along the length direction of the material conveying seat 21. The connecting blocks 32 are sleeved on multiple material conveying pipes 22 and are close to the loading end 24. The connecting plates 31 are detachably connected to the connecting blocks 32 by bolts, thereby connecting multiple material conveying pipes 22 to the connecting blocks 32 through multiple connecting plates 31.

[0051] Reference Figure 4 and Figure 5 The vibrating element 33 is an electromagnetic vibrator, which is a relatively mature technology in the prior art and will not be described in detail here. The vibrating end of the vibrating element 33 abuts against the connecting block 32, so that the vibration of the vibrating element 33 drives the connecting block 32 to vibrate, and the connecting block 32 drives the multiple material conveying pipes 22 to vibrate, so that the components 16 in the multiple material conveying pipes 22 can gradually move along the forward direction of the formation.

[0052] During feeding, by loading the parts 16 from the loading end 24 into the conveying pipe 22, the parts 16 in the conveying pipe 22 can be arranged in a row. By vibrating the vibrating element 33, the parts 16 in the multiple conveying pipes 22 gradually move along the forward direction of the row. The feeding mechanism takes out the parts 16 from the discharge port 23 and puts the parts 16 into the core 15.

[0053] Specifically, refer to Figure 1 and Figure 5 The feeding mechanism includes a base 4 mounted on the worktable 1, a main slider 5 slidably mounted on the base 4, a baffle assembly 6 for preventing the movement of the parts 16 in a queue, and a feeding assembly 7 for picking up materials from the discharge port 23 and feeding them into the mounting slot 14. The base 4 is a long strip-shaped block, distributed along the length of the worktable 1, and has an L-shaped cross-section. The main slider 5 is an L-shaped block, sliding and engaging with the base 4 along the length of the base 4, with its long side distributed along the length of the base 4. Both the baffle assembly 6 and the feeding assembly 7 are connected to the main slider 5. By driving the main slider 5 to slide along the length of the base 4, the baffle assembly 6 and the feeding assembly 7 slide along the material conveying assembly 2 towards or away from the die 12. When the feeding component 7 takes material from the discharge port 23, it drives the main slider 5 to slide along the length of the base 4, thereby moving the baffle component 6 and the feeding component 7, so that the feeding component 7 approaches the die 12 and feeds the material into the mounting slot 14 through the feeding component 7. At the same time, the baffle component 6 blocks the movement of the component 16.

[0054] Reference Figure 1 and Figure 5 A drive base 8 is provided on the worktable 1, located at one end of the base 4 and close to the end of the worktable 1. A first drive component 9 is provided on the drive base 8. The first drive component 9 is used to drive the main slider 5 to slide along the length direction of the base 4. The first drive component 9 is a cylinder, and its driving end is connected to the main slider 5. Thus, the main slider 5 can be easily driven to slide along the length direction of the base 4 via the first drive component 9.

[0055] Specifically, refer to Figure 5 and Figure 6 The baffle assembly 6 includes a slide rod 61 passing through the long side of the main slide block 5, a drive plate 62 slidably disposed on the main slide block 5, and a pressure plate 63 slidably disposed on the drive plate 62.

[0056] Reference Figure 5 and Figure 6 The slide rods 61 are distributed along the width direction of the base 4, that is, along the direction of the alignment of the components 16. The slide rods 61 and the main slider 5 slide and cooperate with each other along the length direction of the slide rods 61. The drive plate 62 is rectangular and is also distributed along the length direction of the base 4. One end of the slide rod 61 is fixedly connected to the drive plate 62, so that when the drive plate 62 is driven, the slide rod 61 restricts the drive plate 62 from sliding along the length direction of the slide rod 61. There are six slide rods 61, which are arranged in an array. The multiple slide rods 61 help to make the sliding process of the drive plate 62 more stable.

[0057] Reference Figure 5 and Figure 6 The pressure plate 63 is also rectangular, and it is located away from the long side of the main slider 5. The pressure plate 63 is distributed along the length of the drive plate 62. A first reset guide 64 is provided between the pressure plate 63 and the drive plate 62. Multiple first reset guides 64 are provided and arranged in an array. When the first drive member 9 drives the main slider 5 to slide along the length of the base 4, the main slider 5 drives the slide rod 61 and the drive plate 62 to move, and the drive plate 62 drives the first reset guides 64 and the pressure plate 63 to move.

[0058] Reference Figure 5 and Figure 6 The first reset guide 64 includes a guide post 641 disposed on the pressure plate 63, a limiting block 642 disposed at one end of the guide post 641, and an elastic member 643 connecting the pressure plate 63 and the drive plate 62. The guide post 641 is also distributed along the width direction of the base 4. One end of the guide post 641 is fixedly connected to the pressure plate 63, and the end of the guide post 641 facing away from the pressure plate 63 passes through the drive plate 62. The limiting block 642 is disposed at the end of the guide post 641 facing away from the pressure plate 63, so that when the pressure plate 63 is driven, the guide post 641 restricts the drive plate 62 from sliding along the length direction of the guide post 641. The elastic element 643 is a spring, sleeved on the guide post 641. One end of the elastic element 643 is connected to the pressure plate 63, and the other end of the elastic element 643, away from the pressure plate 63, is connected to the drive plate 62. The elastic force of the elastic element 643 keeps the pressure plate 63 pressed against the conveyor seat 21, thereby preventing the component 16 from moving. Furthermore, the elastic element 643 helps prevent impact and vibration transmission from the vibrating element 33, and the multiple first reset guides 64 help make the sliding of the pressure plate 63 more stable, preventing the pressure plate 63 from shifting and effectively reducing vibration.

[0059] During loading, the loading assembly 7 picks up the material from the discharge port 23, and drives the main slider 5 to slide along the length of the base 4, causing the pressure plate 63 to abut against the conveyor seat 21, thereby blocking the movement of the part 16. At the same time, the loading assembly 7 is driven to approach the die 12 and load the material into the die 12, thus completing one loading of the part 16.

[0060] Specifically, refer to Figure 7 and Figure 8 The feeding assembly 7 includes a main clamping plate 71 and a secondary clamping plate 72 that are parallel to each other. Both the main clamping plate 71 and the secondary clamping plate 72 are rectangular in shape and the same size. Both the main clamping plate 71 and the secondary clamping plate 72 are distributed along the length direction of the pressure plate 63. The main clamping plate 71 and the secondary clamping plate 72 face each other and are aligned. One long side of the main clamping plate 71 is fixedly connected to the drive plate 62.

[0061] Reference Figure 7 and Figure 8A second reset guide 73 is provided between the main clamping plate 71 and the auxiliary clamping plate 72. Multiple second reset guides 73 are provided, and their structures are identical to those of the first reset guide 64. In the second reset guide 73, guide posts 641 are distributed along the main clamping plate 71 and the auxiliary clamping plate 72, facing each other. One end of the guide post 641 is fixedly connected to the auxiliary clamping plate 72, and the end of the guide post 641 facing away from the pressure plate 63 passes through the main clamping plate 71. A limiting block 642 is provided at the end of the guide post 641 facing away from the auxiliary clamping plate 72. One end of the elastic element 643 in the second reset guide 73 is connected to the main clamping plate 71, and the end of the elastic element 643 facing away from the main clamping plate 71 is connected to the auxiliary clamping plate 72. Through the elastic force of the elastic element 643 in the second reset guide 73, a certain distance is maintained between the auxiliary clamping plate 72 and the main clamping plate 71 in a natural state. Furthermore, the elastic element 643 helps to further prevent the transmission of impact and vibration from the vibrating element 33.

[0062] Continue to refer to Figure 7 and Figure 8 The auxiliary clamping plate 72 has a receiving groove 74 on the side opposite to the main clamping plate 71. The shape of the receiving groove 74 is just right for placing a component 16. There are multiple receiving grooves 74, which are distributed one-to-one with the positions of multiple mounting slots 14. The main clamping plate 71 is provided with a ejector pin 75. The ejector pin 75 is distributed along the main clamping plate 71 and the auxiliary clamping plate 72 facing each other. One end of the ejector pin 75 is connected to the main clamping plate 71, and the end of the ejector pin 75 away from the main clamping plate 71 passes through the auxiliary clamping plate 72 and extends into the receiving groove 74. The ejector pin 75 and the auxiliary clamping plate 72 slide and cooperate with each other along the length direction of the ejector pin 75. When the main clamping plate 71 is driven to slide, the ejector pin 75 pushes the component 16 out of the receiving groove 74.

[0063] Reference Figure 1 and Figure 7When the first driving member 9 drives the main slider 5 to slide along the length direction of the base 4 to the minimum distance, the pressure plate 63 moves away from the material conveying seat 21. The driving plate 62 drives the main clamping plate 71 to move. The main clamping plate 71 drives the second reset guide 73 and the auxiliary clamping plate 72 to move. The auxiliary clamping plate 72 abuts against the material conveying seat 21, and the multiple receiving slots 74 are connected to the multiple discharge ports 23 one by one. Thus, the vibrating member 33 drives the parts 16 in the material conveying pipe 22 to move along the forward direction of the queue, so that the foremost part 16 enters the receiving slot 74. When the first driving member 9 drives the main slider 5 to slide to the maximum distance along the length direction of the base 4, the pressure plate 63 abuts against the material conveying seat 21 and blocks the discharge port 23, and the secondary clamping plate 72 is aligned with the forming groove 13, and the multiple receiving grooves 74 are aligned one-to-one with the multiple mounting grooves 14. Thus, by driving the main clamping plate 71 to move in the direction close to the secondary clamping plate 72, the secondary clamping plate 72 can be extended into and abut against the bottom of the forming groove 13, and the multiple receiving grooves 74 are connected one-to-one with the multiple mounting grooves 14. The pressure plate 63 abuts against the die 12. At the same time, by moving the main clamping plate 71, the driving plate 62 and the sliding rod 61 are driven to move, so that the elastic element 643 in the first reset guide 64 is compressed, thereby avoiding direct collision between the pressure plate 63 and the groove. In addition, by continuously moving the main clamping plate 71 in the direction close to the secondary clamping plate 72, the ejector pin 75 pushes the part 16 in the receiving groove 74 to the mounting groove 14, so that the part 16 can be loaded.

[0064] Reference Figure 1 and Figure 7 A drive frame 10 is mounted on the main slider 5, and the drive frame 10 is positioned away from the drive plate 62. A second drive component 11, which is also a cylinder, is mounted on the drive frame 10. The second drive component 11 is used to drive the main clamping plate 71 to move in a direction closer to or further away from the auxiliary clamping plate 72. The drive end of the second drive component 11 is connected to the main clamping plate 71. Thus, the second drive component 11 drives the main clamping plate 71 to move, causing the auxiliary clamping plate 72 to extend into and abut against the bottom of the forming groove 13, and drives the ejector pin 75 to push the component 16 in the receiving groove 74 to the mounting groove 14. At the same time, the main clamping plate 71 drives the drive plate 62 and the slide rod 61 to move, avoiding direct collision between the pressure plate 63 and the groove.

[0065] The implementation principle of this application is as follows: during material feeding, by loading the parts 16 from the loading end 24 into the conveying pipe 22, the parts 16 in the conveying pipe 22 can be arranged in a row.

[0066] The first driving component 9 drives the main slider 5 to slide along the length of the base 4 to the minimum distance, so that the pressure plate 63 moves away from the material conveying seat 21, the auxiliary clamping plate 72 abuts against the material conveying seat 21, and the multiple receiving slots 74 are connected to the multiple discharge ports 23 one by one. Thus, the vibrating component 33 drives the parts 16 in the material conveying pipe 22 to move along the forward direction of the formation, so that the foremost part 16 enters the receiving slot 74.

[0067] Next, the main slider 5 is driven by the first driving component 9 to slide along the length of the base 4 to the maximum distance, so that the pressure plate 63 abuts against the material conveyor seat 21, the secondary clamping plate 72 is aligned with the forming groove 13, and the multiple receiving grooves 74 are aligned one-to-one with the multiple mounting grooves 14. The main clamping plate 71 is driven by the second driving component 11 to move along the direction close to the secondary clamping plate 72, so that the secondary clamping plate 72 extends into and abuts against the bottom of the forming groove 13. The multiple receiving grooves 74 are connected one-to-one with the multiple mounting grooves 14. As the main clamping plate 71 continues to move along the direction close to the secondary clamping plate 72, the ejector pin 75 pushes the part 16 in the receiving groove 74 into the mounting groove 14, so that the part 16 can be automatically fed.

[0068] Meanwhile, part of the pressure plate 63 abuts against the die 12. The movement of the main clamping plate 71 drives the drive plate 62 and the slide rod 61 to move, compressing the elastic element 643 in the first reset guide 64, thereby preventing the pressure plate 63 from directly colliding with the groove.

[0069] When there are few components 16 remaining in the material conveying pipe 22, components 16 can be loaded into the material conveying pipe 22 from the loading end 24 at any time to replenish them, so that the replenishment process does not affect the operation of the equipment, thereby improving the production efficiency of the bottom shell.

Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
