Description

Technical Field

[0001] This application relates to the field of feeding devices, and more particularly to an automatic feeding device for a motor housing stamping machine. Background Technology

[0002] The material feeding process in the motor housing stamping production line is mostly done manually or semi-automatically. The manual laborer moves the sheet metal to the stamping station and uses a suction cup device to place the sheet metal onto the conveyor belt in sequence so that the stamping station can stamp the sheet metal into the corresponding housing shape.

[0003] The current feeding device mainly consists of a storage rack and a suction cup assembly. The storage rack is used to store the sheet metal to be processed, and the suction cup assembly is used to pick up the sheet metal. The storage rack contains a moving component, which controls the suction cup assembly. The suction cup assembly moves the sheet metal onto the conveyor belt, and the conveyor belt then transports the sheet metal to the stamping station for stamping, so as to process the sheet metal into a shell of the corresponding shape.

[0004] To facilitate storage of the boards, an oil film is usually present on the surface of the boards, preventing direct contact between adjacent boards. During the board loading process, the suction cup device picks up the boards, and due to the oil film, the suction cup device may pick up multiple boards at the same time, leading to loading errors and reducing the overall loading efficiency of the loading device. Summary of the Invention

[0005] To address the aforementioned issues, this application provides an automatic feeding device for a motor housing stamping machine.

[0006] This application provides an automatic feeding device for a motor housing stamping machine, which adopts the following technical solution: An automatic feeding device for a motor housing stamping machine includes a feeding rack and a transfer rack arranged opposite to each other. The feeding rack is provided with a feeding component and a distribution rack. The feeding component is used to transport the sheet metal to the distribution rack. The transfer rack is provided with a transfer component. The distribution rack is provided with a distribution component. The distribution component includes a support and a magnetic sheet separator. The support is disposed on the distribution rack, and the magnetic sheet separator is disposed on the support.

[0007] By adopting the above technical solution, the feeding component conveys the sheet to the powder rack. At this time, the magnetic separator is activated and magnetizes the sheet, so that the side near the magnetic separator generates the same magnetic pole, thereby generating a repulsive force between two adjacent sheets, realizing the function of separating two adjacent sheets, reducing the possibility of multiple sheets being fed at the same time, and thus improving the feeding efficiency of the feeding device.

[0008] Preferably, the feeding assembly includes a storage tray and several sets of guide components. The storage tray is rotatably connected to the feeding frame. Each set of guide components is evenly arranged on the storage tray along its circumference. The feeding frame includes several guide frames. A feeding plate is slidably connected to the feeding frame in the vertical direction. The storage tray has several feeding holes. Each set of guide components is correspondingly arranged at one feeding hole. The feeding frame is equipped with a first cylinder, and the output end of the first cylinder is connected to the feeding plate.

[0009] By adopting the above technical solution, when the sheet material needs to be conveyed to the sorting rack, the first cylinder is activated and controls the movement of the feeding plate. The feeding plate contacts the sheet material and drives it towards the sorting rack. At this time, the guide rack provides guidance for the sheet material, improving the stability of the sheet material during movement. When the sheet material moves to the magnetic separator, adjacent sheet materials are separated to improve the accuracy of subsequent sheet material transfer.

[0010] Preferably, the support is provided with a guide block on the side near the feeding rack, and the guide block is arranged opposite to the corresponding feeding rack.

[0011] By adopting the above technical solution, the guide block compensates for the gap between the guide frame and the material distribution frame, reducing the possibility of the sheet falling during the movement of the sheet, thereby improving the feeding efficiency of the feeding device.

[0012] Preferably, the material sorting rack is provided with a conveying assembly for conveying the sheet material. The conveying assembly includes a conveying frame, a second cylinder, a support plate, and a conveying plate. The conveying frame is disposed on the material sorting rack, the second cylinder is disposed on the conveying frame, the support plate is disposed on the output end of the second cylinder, the conveying plate is disposed on the side of the support plate away from the second cylinder, and the conveying plate is provided with an adsorption assembly.

[0013] By adopting the above technical solution, the second cylinder is activated and drives the support plate and conveyor plate to move. The conveyor plate then drives the adsorption component to move, so that the adsorption component comes into contact with the sheet material. The adsorption component then adsorbs the sheet material after it has been separated by the magnetic separator, so as to transport the sheet material to the transfer component, so that the transfer component can transport the sheet material to the stamping station for stamping.

[0014] Preferably, the adsorption assembly includes a guide sleeve, a connecting tube, and a suction cup. The guide sleeve is disposed on the conveying plate, the connecting tube is slidably connected to the guide sleeve, the connecting tube is connected to the suction cup, an air source is connected to the connecting tube, the suction cup is disposed on the side of the connecting tube away from the conveying plate, and a spring is sleeved on the connecting tube, one end of the spring abutting against the conveying plate and the other end abutting against the suction cup.

[0015] By adopting the above technical solution, the conveyor plate drives the guide sleeve, connecting tube, and suction cup to move, causing the suction cup to come into contact with the material. Simultaneously, the material is adsorbed by the connecting tube and suction cup. When the suction cup contacts the material, the spring is compressed and absorbs some of the impact force, reducing the possibility of damage to the suction cup and the material. After the suction cup separates from the material, the suction cup and connecting tube automatically return to their original positions under the spring's rebound force, allowing for continued use.

[0016] Preferably, the material transfer assembly includes two material transfer seats and several material transfer plates arranged opposite each other. The two material transfer seats are arranged opposite each other on a material transfer frame. The material transfer frame is provided with a control component for controlling the movement of the two material transfer seats opposite each other. Each material transfer plate is arranged on a material transfer seat. Each material transfer plate is provided with a support plate. The support plate is provided with a limiting post for limiting the material plate. The support plate is provided with a clamping arc surface for clamping the material plate. The material transfer frame is provided with a temporary storage rack.

[0017] By employing the above technical solution, the suction cup moves the sheet metal to the transfer plate, at which point the control component drives the two transfer plates to move. When the sheet metal is opposite the support plate, the suction cup releases its grip, and the sheet metal falls onto the support plate under its own gravity. The limiting posts on the support plate then limit the sheet metal's movement. The transfer plate then resets, causing the sheet metal to fall onto the temporary storage rack for temporary storage. The transfer component repeats the above actions, this time with the clamping arc surface on the support plate contacting the sheet metal on the temporary storage rack to control its movement along the rack, thus moving the sheet metal towards the stamping station and achieving the function of conveying the sheet metal.

[0018] Preferably, the control component includes a bidirectional screw and several linear modules. The bidirectional screw is rotatably connected to a transfer frame, and a control motor is provided on the transfer frame. The output end of the control motor is connected to the bidirectional screw. A control plate is threadedly connected to each of the two threaded ends of the bidirectional screw. The control plate is slidably connected to the transfer frame, and a linear module is correspondingly provided on the control plate. The output end of the linear module is connected to the transfer seat at the corresponding position.

[0019] By adopting the above technical solution, a control motor drives a bidirectional screw to rotate, which in turn controls two control boards to move synchronously. The control boards then control the movement of linear modules at corresponding positions. The linear modules, in turn, control the movement of transfer seats at corresponding positions. The transfer seats, in turn, control the movement of transfer plates and support plates to transport the sheet material.

[0020] Preferably, the transfer rack is provided with a centering component for centering the plates on the temporary storage rack. The centering component includes a box and two centering plates arranged opposite each other. The box is slidably connected to the transfer rack in the vertical direction. The two centering plates arranged opposite each other are slidably connected in the box. The centering plates are provided with centering blocks. The box is provided with a drive component for controlling the two centering plates to move in opposite directions.

[0021] By adopting the above technical solution, after the sheet material falls onto the temporary storage rack, the box moves towards the rack, while the drive assembly drives and controls the movement of two alignment plates. The two alignment plates control the movement of the alignment blocks at corresponding positions, and the alignment blocks contact the sheet material on the temporary storage rack to center the sheet material. This reduces the possibility of the sheet material falling due to deviation between itself and the temporary storage rack, and improves the stability of the sheet material during transport.

[0022] Preferably, the driving assembly includes a first rack, a first gear, a second gear, and a driving gear. The first rack is vertically mounted on the transfer frame. The housing is slidably connected to the first rack. Both the first gear and the second gear are rotatably connected in the housing. The first gear meshes with the first rack. The side of the first gear away from the first rack meshes with the second gear. The driving gear is mounted on the shaft of the second gear. Two opposing centering plates each have a second rack on their opposite sides. The driving gear meshes with both second racks simultaneously. The transfer frame has a third cylinder, the output end of which is connected to the housing. The transfer frame has several guide rods, and the housing is slidably connected to each guide rod.

[0023] By adopting the above technical solution, the third cylinder controls the movement of the box body, at which time the guide rod provides guidance for the box body. Simultaneously, under the action of the first rack, the first gear rotates. The first gear then sequentially controls the rotation of the second gear and the drive gear. The drive gear simultaneously contacts the two second racks and drives them to move in opposite directions. The second racks control the movement of the corresponding centering plate, which in turn drives the movement of the corresponding centering block, so that the two opposing centering blocks can center the plate material.

[0024] In summary, this application includes at least one of the following beneficial technical effects: By setting up a magnetic separator, the sheet metal is magnetized, which separates two adjacent sheets, reducing the possibility of multiple sheets being fed at the same time, thereby improving the feeding efficiency of the feeding device. By setting guide blocks, the distance between the guide frame and the material distribution frame is compensated, reducing the possibility of the sheet falling during the conveying process, thereby improving the stability of the feeding device during use; By setting up a centering component to center the boards on the temporary storage rack, the possibility of the boards falling off the rack is reduced, thereby further improving the feeding efficiency of the feeding device.

[0027] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail. Example

[0028] Embodiment 1 of this application discloses an automatic feeding device for a motor housing stamping machine. (Refer to...) Figure 1 and Figure 2An automatic feeding device for a motor housing stamping machine includes a feeding rack 1 and a transferring rack 2 arranged opposite to each other. The feeding rack 1 is equipped with a feeding assembly 11 and a separating rack 12. The separating rack 12 is equipped with a separating assembly 3, which includes a support 31 and a magnetic separator 32. The support 31 is mounted on the separating rack 12, and the magnetic separator 32 is fixed to the support 31. The feeding assembly 11 is used to transport the sheet metal to the magnetic separator 32. The magnetic separator 32 magnetizes the sheet metal, causing a repulsive force between adjacent sheets, thus separating them and reducing the possibility of multiple sheets being fed simultaneously, thereby improving the feeding efficiency of the feeding device.

[0029] Reference Figure 1 The feeding assembly 11 includes a storage tray 111 and several sets of guide components. The storage tray 111 is rotatably connected to the feeding frame 1, and each set of guide components is evenly arranged on the storage tray 111 along the circumference of the storage tray 111. A drive motor 13 is provided on the feeding frame 1, and the output end of the drive motor 13 is connected to the storage tray 111.

[0030] The material guiding components include several material guide frames 112, which are evenly arranged in a circumferential direction, forming a material guiding space for storing the sheet metal. A feeding plate 14 is slidably connected to the feeding rack 1 in the vertical direction. Several feeding holes 113 are opened on the storage tray 111, and each set of material guiding components is correspondingly positioned at one feeding hole 113. A first cylinder 15 is also provided on the feeding rack 1, and the output end of the first cylinder 15 is connected to the feeding plate 14.

[0031] Workers place the sheets to be processed in the guide spaces between the various guide racks 112. The drive motor 13 controls the rotation of the storage tray 111, aligning the guide space containing the sheets with the loading plate 14. The first cylinder 15 starts and moves the loading plate 14, which in turn moves each sheet towards the separating rack 12. When the sheet moves to the magnetic separator 32, the magnetic separator 32 magnetizes the sheet, creating a repulsive force between adjacent sheets, thus automatically separating them for more precise transfer to the stamping station.

[0032] Reference Figure 2 In order to improve the stability of the plate when it moves, a guide block 311 is fixed on the side of the support 31 near the feeding rack 1. The guide block 311 is set opposite to the guide rack 112 at the corresponding position.

[0033] The guide block 311 compensates for the gap between the guide frame 112 and the feeding frame 1, reducing the possibility of the board falling when the feeding plate 14 moves the board, so that the board can move more stably to the magnetic separator 32.

[0034] Reference Figure 3 and Figure 4 The material distribution rack 12 is equipped with a conveying assembly 4 for conveying sheet metal. The conveying assembly 4 includes a conveying frame 41, a second cylinder 42, a support plate 43, and a conveying plate 44. The conveying frame 41 is fixed on the material distribution rack 12, and the second cylinder 42 is fixed vertically on the conveying frame 41. The support plate 43 is located on the output end of the second cylinder 42, and the conveying plate 44 is located on the side of the support plate 43 away from the second cylinder 42.

[0035] Furthermore, an adsorption assembly 45 is provided on the conveyor plate 44. The adsorption assembly 45 includes a guide sleeve 451, a connecting pipe 452, and a suction cup 453. The guide sleeve 451 is fixed on the conveyor plate 44, and the connecting plate is slidably connected to the guide sleeve 451. The connecting pipe 452 is connected to the suction cup 453, and an air source is connected to the connecting pipe 452. The suction cup 453 is located on the side of the connecting pipe 452 away from the conveyor plate 44. A spring 454 is sleeved on the connecting pipe 452. One end of the spring 454 is connected to the conveyor plate 44, and the other end abuts against the suction cup 453.

[0036] The second cylinder 42 controls the movement of the support plate 43 and the conveying plate 44, which in turn moves the suction assembly 45 toward the sheet metal. After the suction cup 453 comes into contact with the sheet metal, it adheres to the sheet metal under the action of the connecting pipe 452 and the air source, allowing it to be transferred to the stamping station later. Furthermore, when the suction cup 453 contacts the sheet metal, the spring 454 absorbs some of the impact force, reducing the possibility of damage to both the suction cup 453 and the sheet metal, thus further improving the stability of the feeding device during operation.

[0037] Reference Figure 3 and Figure 4 The transfer rack 2 is equipped with a transfer component 21, which is used to gradually transfer the sheet material on the sheet suction cup 453 to the stamping station.

[0038] The material transfer assembly 21 includes two material transfer seats 211 and several material transfer plates 212 arranged opposite to each other. The two material transfer seats 211 are slidably connected to the material transfer frame 2, and several material transfer plates 212 are provided on each of the two material transfer seats 211. Each material transfer plate 212 is evenly arranged on the material transfer seat 211 at a corresponding position along the length direction of the material transfer seat 211. Each material transfer plate 212 is fixed with a support plate 213, and a limiting post 214 for limiting the material is fixed on the support plate 213.

[0039] Reference Figure 1 and Figure 3The transfer rack 2 is equipped with a control component 5 for controlling the movement of the transfer seats 211. The control component 5 includes a bidirectional screw 51 and several linear modules 52. The bidirectional screw 51 is rotatably connected to the transfer rack 2. A control motor 22 is fixed on the transfer rack 2, and the output end of the control motor 22 is connected to the bidirectional screw 51. A control plate 53 is threadedly connected to each of the two threaded ends of the bidirectional screw 51, and the control plate 53 is slidably connected to the transfer rack 2. A linear module 52 is correspondingly set on the control plate 53, and each transfer seat 211 corresponds to a linear module 52. The output end of the linear module 52 is connected to the transfer seat 211 at the corresponding position, and the linear module 52 is driven by a motor.

[0040] Reference Figure 3 and Figure 4 The transfer rack 2 is fixed with a temporary storage rack 6 for storing the board, and the support plate 213 is provided with a clamping arc surface 215 for clamping the board.

[0041] The control motor 22 drives the bidirectional screw 51 to rotate, which in turn drives two control plates 53 to move in opposite directions. The control plates 53 then control the linear module 52 at the corresponding position to move, which in turn controls the transfer seat 211 to move, and the transfer seat 211 controls the transfer plate 212 at the corresponding position to move. The transfer plate 212 then controls the support plate 213 and the limiting post 214 at the corresponding position to move. At this time, a limiting space for storing the sheet material is formed between the limiting posts 214 on the two opposing support plates 213. The suction cup 453 releases its grip on the sheet material, allowing it to fall onto the support plate 213 under its own gravity. The linear module 52 then controls the transfer seat 211 and the transfer plate 212 to reset, so that the sheet material is aligned with the temporary storage rack 6. Simultaneously, the two control plates 53 reset, allowing the sheet material to fall onto the temporary storage rack 6. The transfer assembly 21 then repeats the above actions to move new sheet materials onto the temporary storage rack 6. At the same time, the sheet material on the temporary storage rack 6 comes into contact with the clamping arc surface 215. At this time, the transfer seat 211 can control the sheet material on the temporary storage rack 6 to gradually move to the stamping station, realizing the function of automatic sheet material feeding.

[0042] The implementation principle of Embodiment 1 of this application is as follows: During the feeding process of the sheet material, the feeding component 11 conveys the sheet material to the separating rack 12. When the sheet material is opposite to the magnetic separator 32, the magnetic separator 32 is activated and magnetizes the sheet material, so that a repulsive force is generated between two adjacent sheets material, realizing the function of automatically separating the sheet material, reducing the possibility of feeding multiple sheets material at the same time, thereby improving the feeding efficiency of the feeding device. Example

[0043] Reference Figure 5 and Figure 6The difference from Embodiment 1 of this application is that, in order to improve the stability of the material moving on the temporary storage rack 6, the transfer rack 2 is provided with a centering component 7 for centering the material on the temporary storage rack 6. The centering component 7 includes a housing 71 and two opposing centering plates 72. The housing 71 is slidably connected to the transfer rack 2 in the vertical direction, and the two opposing centering plates 72 are slidably connected in the housing 71. Centering blocks 73 are provided on the centering plates 72, and a drive component 8 for controlling the two centering plates 72 to move in opposite directions is provided in the housing 71.

[0044] Reference Figure 5 and Figure 6 The drive assembly 8 includes a first rack 81, a first gear 82, a second gear 83, and a drive gear 84. The first rack 81 is vertically mounted on the transfer frame 2, and the housing 71 is slidably connected to the first rack 81. The first gear 82 and the second gear 83 are both rotatably connected in the housing 71, and the first gear 82 meshes with the first rack 81. The side of the first gear 82 away from the first rack 81 meshes with the second gear 83, and the drive gear 84 is mounted on the shaft of the second gear 83.

[0045] Each of the two opposing centering plates 72 has a second rack 85 on one side, and the drive gear 84 meshes with both second racks 85 simultaneously. A third cylinder 23 is fixed on the transfer frame 2, and the output end of the third cylinder 23 is connected to the box body 71. The transfer frame 2 is also provided with several guide rods 24, and the box body 71 is slidably connected to each guide rod 24.

[0046] The implementation principle of Embodiment 2 of this application is as follows: After the board falls onto the temporary storage rack 6, the third cylinder 23 controls the movement of the box 71, at which time the guide rod 24 provides guidance for the box 71. Simultaneously, under the action of the first rack 81, the first gear 82 rotates. The first gear 82 then sequentially controls the rotation of the second gear 83 and the drive gear 84. The drive gear 84 simultaneously contacts the two second racks 85 and drives the two second racks 85 to move in opposite directions. The second racks 85 control the movement of the corresponding centering plate 72, and the centering plate 72 then drives the movement of the corresponding centering block 73. The two centering blocks 73 simultaneously contact the board and control the movement of the board 53, so that the two opposing centering blocks 73 can perform centering processing on the board.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
