Description

Technical Field

[0001] This application relates to the field of electrical component crushing, and in particular to a crushing device for electrical components. Background Technology

[0002] In the field of electrical component processing, crushing equipment has always been a crucial component. By crushing electrical components, sorting operations can be made more convenient, different types of electrical components can be separated, and resources can be effectively recycled and reused.

[0003] In existing crushing machinery, hydraulic equipment is commonly used to crush electrical components, achieving crushing by extending and retracting the piston rod of a hydraulic cylinder. However, in actual electrical component processing, traditional crushing equipment often struggles to achieve precise operation for components requiring localized processing. Since traditional crushing methods mostly employ overall pressure crushing, for electrical components requiring only localized crushing, this not only leads to energy waste but may also cause unnecessary damage to the un-crushable parts, thus affecting the subsequent reuse value of the electrical components. Utility Model Content

[0004] In order to improve the problem that traditional equipment is difficult to accurately crush electrical components locally, this application provides a crushing device for electrical components.

[0005] The technical solution of the crushing equipment for electrical components provided in this application is as follows: A crushing device for electrical components includes a base frame and a support frame fixed on the base frame. A worktable is fixed on the base frame, and a clamping assembly for fixing electrical components is provided on the worktable. The clamping assembly includes a first clamping part for laterally limiting the electrical components and a second clamping part for vertically limiting the electrical components. A claw assembly for partially crushing electrical components is also provided on the base frame. A placement platform is fixed on the base frame, and a pressing assembly for pressing down the electrical components is provided directly above the placement platform.

[0006] By adopting the above technical solution, the pressing component can apply pressure to the electrical components on the placement table, thereby achieving overall crushing of the electrical components. For electrical components that require partial crushing, the first clamping component and the second clamping component cooperate to limit and fix the electrical components, effectively preventing the electrical components from shifting or shaking during the crushing process. At the same time, the gripper assembly can perform localized clamping and crushing of the electrical components that are already fixed on the worktable.

[0007] Optionally, the first clamping component includes a fixing block, a lead screw, a first clamping plate, and a limiting plate. The fixing block is fixed on the worktable, the limiting plate is fixed on the first clamping plate, the first clamping plate and the limiting plate form a limiting space, the bottom of the first clamping plate is in contact with the worktable, one end of the lead screw passes through the fixing block and is threaded to the inner wall of the fixing block, and the other end of the lead screw is rotatably connected to the first clamping plate.

[0008] By adopting the above technical solution, when it is necessary to laterally limit the electrical components, the lead screw is rotated. Since the lead screw is threadedly connected to the fixed block, the lead screw will push the first clamping plate to slide on the worktable, so that the limiting space formed by the first clamping plate and the limiting plate gradually approaches the electrical components until the electrical components are tightly clamped in the limiting space, thereby achieving lateral limiting of the electrical components.

[0009] Optionally, the second clamping component includes a connecting plate, a quick clamp, and a second clamping plate. The connecting plate is fixed on the worktable, the bottom of the second clamping plate is in contact with the worktable, the quick clamp is mounted on the connecting plate, and the telescopic rod of the quick clamp is fixed on the second clamping plate.

[0010] By adopting the above technical solution, when vertical positioning of electrical components is required, the quick-release clamp is operated. The telescopic rod of the quick-release clamp drives the second clamping plate to slide on the worktable, tightly pressing the electrical component between the first clamping component and the second clamping plate, thus achieving vertical positioning of the electrical component. Through the cooperation of the first and second clamping components, the electrical component can be positioned in both the lateral and longitudinal directions, ensuring its stability during local crushing and breaking.

[0011] Optionally, the gripper assembly includes a first hydraulic cylinder, a mounting sleeve, a support plate, and at least a pair of symmetrically arranged gripping components. A bracket is fixed on the support frame. The first hydraulic cylinder and the mounting sleeve are both fixed on the bracket. The mounting sleeve is located between the first hydraulic cylinder and the support plate. The piston rod of the first hydraulic cylinder passes through the mounting sleeve and is fixedly connected to the support plate. The gripping components include a gripper and a connecting plate. The gripper is hinged to the mounting sleeve. Both ends of the connecting plate are respectively hinged to the gripper and the support plate. A controller is provided on the support frame. The first hydraulic cylinder is electrically connected to the controller.

[0012] By adopting the above technical solution, when it is necessary to control the gripping and pressing component to locally crush electrical components, the controller activates the piston rod of the first hydraulic cylinder to extend or retract. The movement of the piston rod of the first hydraulic cylinder drives the support plate to move, and the support plate pulls the gripper to rotate around the hinge point through the connecting plate, thereby realizing the opening or closing of the gripping and pressing component and completing the local gripping and crushing of the electrical components.

[0013] Optionally, the pressing assembly includes a second hydraulic cylinder, a mounting plate, a pressure block, and a protective cover. The second hydraulic cylinder is fixed on the support frame, and the piston rod of the second hydraulic cylinder is fixed to the mounting plate. The pressure block is fixed on the mounting plate, and the protective cover is fixed on the mounting plate. A limiting groove is provided on the placement platform, and the shape of the limiting groove is adapted to the shape of the bottom of the pressure block. The second hydraulic cylinder is electrically connected to the controller.

[0014] By adopting the above technical solution, when it is necessary to control the pressing component to crush electrical components, the controller activates the piston rod of the second hydraulic cylinder to extend or retract. The movement of the piston rod of the second hydraulic cylinder drives the mounting plate to move, and the mounting plate drives the pressure block and protective cover to move downward together. When the pressure block enters the limiting groove on the placement platform, it crushes the electrical components placed in the limiting groove. The protective cover protects and prevents the electrical components from splashing.

[0015] Optionally, a limiting component is connected between the mounting plate and the support frame. The limiting component is used to prevent the piston rod of the second hydraulic cylinder from deflecting. The limiting component includes a connecting column and a limiting sleeve. The connecting column is fixed on the mounting plate, and the limiting sleeve is fixed on the support frame. When the piston rod of the second hydraulic cylinder moves, it drives the connecting column to slide in the limiting sleeve.

[0016] By adopting the above technical solution, when the piston rod of the second hydraulic cylinder extends or retracts, the connecting column is slidably connected in the limiting sleeve, and the limiting sleeve can provide a stable guiding effect for the connecting column, thereby effectively preventing the deflection of the piston rod of the second hydraulic cylinder and ensuring that the pressure block can accurately press down and crush the electrical components placed in the limiting groove.

[0017] Optionally, a handle is provided at the end of the lead screw away from the first clamping plate.

[0018] By adopting the above technical solution, the operator can rotate the screw by turning the handle to adjust the distance between the first clamping plate and the second clamping plate, thereby meeting the clamping requirements of electrical components of different sizes and improving the applicability and ease of operation of the crushing equipment.

[0019] Optionally, the bottom of the base frame is equipped with several wheels, all of which are omnidirectional brake wheels, to facilitate the movement and braking of the crushing equipment.

[0020] By adopting the above technical solution, when the crushing equipment needs to be moved, the operator only needs to push the equipment, and the omnidirectional brake wheels can easily move the equipment to the designated position. Once the equipment has moved to the appropriate position, the wheels are locked by the braking function to prevent the equipment from slipping during use, thus ensuring the stability and safety of the crushing equipment during operation.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. The clamping assembly includes a first clamping component for lateral limiting and a second clamping component for vertical limiting, which can accurately fix electrical components in multiple directions, ensuring the stability of electrical components during crushing and improving the crushing effect; 2. The clamping assembly and the gripper assembly work together. The clamping assembly fixes the electrical components that need to be locally crushed, and the controller controls the gripper assembly to work, so as to crush the electrical components that need to be locally crushed. 3. The controller controls the pressing component to work, driving the pressing block to move and crush the electrical components placed in the limit groove, thus achieving the overall crushing of the electrical components; 4. The limiting components and the limiting groove work together to effectively limit the displacement of electrical components during the crushing process, thereby further improving the crushing quality.

[0025] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0026] This application discloses a crushing device for electrical components.

[0027] Reference Figure 1 A crushing device for electrical components includes a controller 11 and a base frame 1. Four wheels 15, all of which are omnidirectional brake wheels, are mounted around the bottom of the base frame 1. When the crushing device needs to be moved, the operator simply pushes the device, and the omnidirectional brake wheels allow the device to be easily moved to the designated position. Once the device is in the appropriate position, the wheels 15 are locked by the braking function to prevent slippage during use, ensuring the stability and safety of the crushing device during operation.

[0028] Reference Figure 1 The base frame 1 serves as the supporting foundation for the entire equipment, and a support frame 2 and a placement platform 8 are fixed on the base frame 1. The placement platform 8 is used to support the electrical components to be crushed. A pressing assembly 9 for crushing the electrical components as a whole is set on the support frame 2, and the pressing assembly 9 is directly above the placement platform 8. A controller 11 is installed on the support frame 2, and the controller 11 can control the operation of the pressing assembly 9.

[0029] Reference Figure 2 A workbench 3 is fixed on the base frame 1. A clamping assembly 4 for holding and fixing electrical components requiring partial crushing is installed on the workbench 3. A bracket 10 is fixed on the support frame 2. A gripper assembly 7, which works in conjunction with the clamping assembly 4 for partial crushing of electrical components, is installed on the bracket 10. A controller 11 controls the operation of the gripper assembly 7. Under the command of the controller 11, the gripper assembly 7 can perform partial clamping and crushing of the electrical components fixed on the workbench 3 by the clamping assembly 4, further improving the crushing flexibility of the equipment.

[0030] Reference Figure 2 A support frame 16 is fixed on the carrier frame 2, a first oil pump 17 is fixed on the support frame 16, a second oil pump 18 is also fixed on the support frame 16, and an oil tank 19 is fixed on the base frame 1. The first oil pump 17 is connected to the oil tank 19 and the gripper assembly 7 via a pipeline, providing power support for the operation of the gripper assembly 7. The second oil pump 18 is connected to the oil tank 19 and the pressing assembly 9 via a pipeline, providing power support for the operation of the pressing assembly 9.

[0031] Reference Figure 3 The pressing assembly 9 includes a second hydraulic cylinder 91, a mounting plate 92, a pressing block 93, and a protective cover 94. The cylinder body of the second hydraulic cylinder 91 is fixed on the support frame 2, and its piston rod is fixed to the mounting plate 92. The pressing block 93 is fixed on the mounting plate 92. The protective cover 94 is fixed on the mounting plate 92 to prevent electrical components from splashing. A limiting groove 12 adapted to the bottom shape of the pressing block 93 is provided on the placement platform 8 to limit the electrical components and prevent them from shifting or sliding during the crushing process, further ensuring the accuracy of crushing.

[0032] Reference Figure 3 The second oil pump 18 is connected to the oil tank 19 and the second hydraulic cylinder 91 via pipelines and is controlled by the controller 11. When it is necessary to control the pressing component to crush electrical components, the controller 11 starts the second oil pump 18. The second oil pump 18 draws hydraulic oil from the oil tank 19 and delivers it to the second hydraulic cylinder 91 through pipelines, driving the piston rod to extend or retract, thereby moving the pressing block 93. When the pressing block 93 enters the limiting groove 12, the pressing block 93 applies uniform and strong pressure to the electrical components placed in the limiting groove 12, thereby achieving overall crushing of the electrical components.

[0033] Reference Figure 3 A limiting assembly 13 is connected between the mounting plate 92 and the support frame 2 to prevent the piston rod of the second hydraulic cylinder 91 from deflecting. The limiting assembly 13 includes a connecting post 131 and a limiting sleeve 132. The connecting post 131 is fixed to the mounting plate 92, and the limiting sleeve 132 is fixed to the support frame 2. The connecting post 131 slides in the limiting sleeve 132.

[0034] Reference Figure 3 When the piston rod of the second hydraulic cylinder 91 moves, it drives the connecting column 131 to slide in the limiting sleeve 132. The limiting sleeve 132 provides a stable guiding effect for the connecting column 131, effectively preventing the deflection of the piston rod of the second hydraulic cylinder 91, and ensuring that the pressure block 93 can accurately press down and crush the electrical components placed in the limiting groove 12.

[0035] Reference Figure 1 and Figure 4 The clamping assembly 4 consists of a first clamping component 5 for lateral limiting of electrical components and a second clamping component 6 for vertical limiting of electrical components. Through the coordinated action of the first clamping component 5 and the second clamping component 6, the electrical components that need to be partially crushed are firmly fixed on the worktable 3, effectively preventing the electrical components from shifting or shaking during the crushing process, ensuring that the position to be partially crushed is directly aligned with the gripper assembly 7, thereby facilitating the subsequent activation of the gripper assembly 7 to partially crush the electrical components.

[0036] Reference Figure 4 The first clamping component 5 includes a fixing block 51, a lead screw 52, ​​a first clamping plate 53, and a limiting plate 54. The fixing block 51 is fixed on the worktable 3, and the limiting plate 54 is fixed on the side of the first clamping plate 53 away from the second clamping component 6. The first clamping plate 53 and the limiting plate 54 form a limiting space, which is used to place electrical components and realize the lateral limiting of the electrical components.

[0037] Reference Figure 4 The first clamping plate 53 slides on the worktable 3, and its movement is guided by sliding. The lead screw 52 passes through the fixing block 51 and is threaded to the inner wall of the fixing block 51, and the end of the lead screw 52 near the second clamping component 6 is rotatably connected to the first clamping plate 53. A rotating handle 14 is provided at the end of the lead screw 52 away from the first clamping plate 53 to facilitate the operator to rotate the lead screw 52.

[0038] Reference Figure 4 In this embodiment, the handle 14 consists of a limiting ball and a connecting rod fixed to the limiting ball. The handle 14 is inserted into the end of the lead screw 52, ​​and under the limiting action of the limiting ball, the handle 14 is prevented from coming off the end of the lead screw 52.

[0039] When it is necessary to laterally limit the electrical components, the operator only needs to turn the handle 14 to drive the lead screw 52 to rotate. Due to the threaded connection between the lead screw 52 and the fixed block 51, the lead screw 52 will push the first clamping plate 53 to slide on the worktable 3, so that the limiting space gradually approaches the electrical components, thereby realizing the vertical limiting of the electrical components.

[0040] Reference Figure 4 The second clamping component 6 includes a connecting plate 61, a quick clamp 62, and a second clamping plate 63. The connecting plate 61 is fixed on the worktable 3, providing an installation position for the quick clamp 62 and the second clamping plate 63. The second clamping plate 63 slides on the worktable 3, the quick clamp 62 is mounted on the connecting plate 61, and the telescopic rod of the quick clamp 62 is fixed on the second clamping plate 63.

[0041] Reference Figure 4In this embodiment, the quick clamp 62 is a manual quick clamp 62. When it is necessary to longitudinally limit the electrical components, the quick clamp 62 is operated. The telescopic rod of the quick clamp 62 will drive the second clamping plate 63 to slide on the worktable 3, tightly pressing the electrical components between the first clamping component 5 and the second clamping plate 63, thereby achieving longitudinal limitation of the electrical components. With the cooperation of the first clamping component 5 and the second clamping component 6, the electrical components can be accurately limited in both the lateral and longitudinal directions, ensuring that the electrical components remain stable during local crushing and breaking.

[0042] Reference Figure 2 and Figure 5 The gripper assembly 7 includes a first hydraulic cylinder 71, a mounting sleeve 72, a support plate 73, and at least a pair of symmetrically arranged gripping and pressing components 74. The cylinder body of the first hydraulic cylinder 71 and the mounting sleeve 72 are both fixed to the bracket 10, with the mounting sleeve 72 located between the first hydraulic cylinder 71 and the support plate 73. The piston rod of the first hydraulic cylinder 71 passes through the mounting sleeve 72 and is fixedly connected to the support plate 73.

[0043] Reference Figure 5 In this embodiment, the gripping and pressing components 74 are configured as a pair, arranged symmetrically from top to bottom. The gripping and pressing components 74 include a gripper 741 and a connecting plate 742, wherein the gripper 741 is hinged to the mounting sleeve 72, and the two ends of the connecting plate 742 are respectively hinged to the gripper 741 and the bearing plate 73.

[0044] Reference Figure 2 and Figure 5 The first oil pump 17 is connected to the oil tank 19 and the first hydraulic cylinder 71 via pipelines and is controlled by the controller 11. When it is necessary to control the gripping component 74 to locally crush electrical components, the controller 11 starts the first oil pump 17. The first oil pump 17 draws hydraulic oil from the oil tank 19 and delivers it to the first hydraulic cylinder 71 through pipelines, driving the piston rod to extend or retract, thereby driving the support plate 73 to move. The support plate 73 pulls the gripper 741 to rotate around the hinge point through the connecting plate 742, realizing the opening or closing of the gripping component 74, and completing the local gripping and crushing of electrical components.

[0045] The implementation principle of a crushing device for electrical components according to an embodiment of this application is as follows: The crushing device controls the pressing component 9, the clamping component 4, and the gripper component 7 through a controller 11, realizing the coordinated operation of each component. The clamping component 4 uses a first clamping part 5 and a second clamping part 6 to limit and fix the electrical components, preventing displacement and shaking during crushing. The pressing component 9 uses a second hydraulic cylinder 91 and a pressure block 93 to press down on the electrical components, and the limiting component 13 ensures the stability and accuracy of the pressing. The gripper component 7 uses a first hydraulic cylinder 71 and a gripper 741 to perform clamping and disassembling operations on the electrical components. Compared with traditional crushing equipment, this equipment can not only achieve overall crushing of electrical components, but also perform partial crushing, and has stronger applicability and flexibility.
