Description

Technical Field

[0001] This utility model relates to the field of automotive parts disassembly technology, and more specifically, to a positioning and separation device for non-destructive disassembly of automotive parts. Background Technology

[0002] With the surge in car ownership, the demand for recycling and reusing end-of-life vehicles has become prominent. Traditional dismantling methods are prone to damaging parts and reducing the reuse rate. To solve this problem, there is an urgent need for non-destructive dismantling technology, the core of which is to maintain the integrity of parts during dismantling. Existing technologies still have room for improvement in terms of positioning accuracy of complex structural parts and automated separation efficiency, so it is necessary to promote the optimization of technology in this field to adapt to the needs of the circular economy.

[0003] Utility model patent CN221809076U discloses a multi-functional press for disassembling automotive parts, including a work box, a hydraulic cylinder, and support seats. Support seats are fixedly installed on both sides of the lower surface of the work box. The hydraulic cylinder is fixedly installed on the top of the work box via a pressure sleeve. The lower end of the hydraulic cylinder's push rod extends into the work box and is fixedly installed with a first flange. A top cone is installed on the lower side of the first flange via a connector. A flow guide port is provided at the bottom of the work box, and a filter plate is installed inside the flow guide port. A worktable is placed on the lower inner surface of the work box, and a baffle is fixedly installed on the front side of the lower surface of the work box. A pair of guide plates are fixedly installed on the lower surface of the work box, and a solid-liquid separation box is installed between the guide plates. A collection bucket is placed below the solid-liquid separation box. This utility model allows for easy replacement of the top cone via the connector; it can perform solid-liquid separation of the liquid inside the parts, facilitating recycling and reuse; and it can also flip the parts.

[0004] Although this multi-functional automotive parts disassembly press facilitates the separation of disassembled parts and fluids, making subsequent recycling easier, the device still has the following problems in practical use: the disassembly process is destructive, which can damage the parts themselves, making it difficult to retain reusable complete components. Therefore, we propose a positioning and separation device for non-destructive disassembly of automotive parts. Utility Model Content

[0005] In view of the aforementioned shortcomings of the existing technology that easily cause damage to parts, it is desirable to provide a positioning and separation device for non-destructive disassembly of automotive parts.

[0006] In a first aspect, this application provides a positioning and separation device for non-destructive disassembly of automotive parts, including a base. A vertically arranged partition is fixedly connected to the top surface of the base. A positioning component and a disassembly component are respectively installed on both sides of the partition on the top surface of the base. The positioning component includes a lifting plate disposed above the base. An operating plate is rotatably connected to the top surface of the lifting plate. Two opposing clamping plates are slidably connected to the top surface of the operating plate. A bidirectional lead screw, threaded to both clamping plates, is rotatably engaged inside the side wall of the operating plate. The disassembly component includes a disassembly box with an opening near the partition and a disassembly motor with an output shaft slidably inserted into the vertical side wall of the disassembly box away from the partition. A turntable is rotatably engaged inside the open end of the disassembly box. Several screwdrivers of different types are slidably inserted into the turntable. An L-shaped plate for supporting the disassembly motor is fixedly installed on the outer side of the vertical side wall of the disassembly box.

[0007] According to the technical solution provided in the embodiments of this application, the positioning component further includes a hydraulic cylinder fixedly installed on the top surface of the base. The extension rod of the hydraulic cylinder is vertically upward and the end of the rod is fixedly connected to the bottom surface of the lifting plate at the center. A waterproof shell is fixedly installed on the bottom surface of the lifting plate. The top surface of the operating plate has two sliding grooves for accommodating the two clamping plates to slide together. Several water leakage holes are opened in the sliding grooves.

[0008] In this setup, precise height adjustment is achieved through hydraulic drive, adapting to the disassembly requirements of parts of different sizes and enhancing the flexibility and adaptability of the device.

[0009] According to the technical solution provided in the embodiments of this application, the bottom surface of the operation panel is coaxially connected to a gear that is rotatably connected to the top surface of the lifting plate, and a rotating motor is fixedly installed on the bottom surface of the lifting plate inside the waterproof shell. The output shaft of the rotating motor passes through the lifting plate and is coaxially connected to another gear, and the two gears mesh with each other.

[0010] This setting solves the problem of disassembling screws in different directions of parts by adjusting the angle of the rotating control panel, eliminating the need for manual adjustment of the parts' positions and improving disassembly efficiency.

[0011] According to the technical solution provided in the embodiments of this application, the two clamping plates are respectively threaded to the two helical segments of the bidirectional lead screw with opposite helical directions, and the smooth section of one end of the bidirectional lead screw passes through the side wall of the operating plate and is coaxially connected to a rotating wheel;

[0012] In this setup, a rotating wheel drives a bidirectional lead screw to rotate, causing two clamping plates to slide in opposite directions, thereby clamping the parts to be disassembled.

[0013] According to the technical solution provided in the embodiments of this application, the number of the plurality of screwdrivers is at least three and they are distributed in a ring at equal intervals. The output shaft of the disassembly motor is located on the circular trajectory where the centers of the plurality of screwdrivers are located. A reducer for driving the turntable to rotate is installed in the disassembly box. The output shaft of the reducer is coaxially connected to the center of the turntable. An encoder and a microcontroller are also installed in the disassembly box. The microcontroller is connected to the reducer and the encoder via signal lines.

[0014] In this setup, the circular screwdriver design enables quick tool changing, reducing the time spent manually changing tools and improving disassembly efficiency; the combination of the reducer, encoder, and microcontroller can prevent positioning deviations caused by excessive rotation speed.

[0015] According to the technical solution provided in the embodiments of this application, the screwdriver has a snap-fit ​​groove at one end inside the disassembly box, and a magnetic block that matches the size of the snap-fit ​​groove is fixedly connected to the shaft end of the disassembly motor inside the disassembly box. A second limiting ring for preventing it from slipping out is fixedly connected to the outer side of the shaft end of the disassembly motor inside the disassembly box.

[0016] In this design, the magnetic connection simplifies the screwdriver and motor connection, making tool replacement easier. The second limit ring ensures the stability of power transmission and prevents tools from falling off during disassembly.

[0017] According to the technical solution provided in the embodiments of this application, the screwdriver is fixedly fitted with a first limiting ring on the outer side wall of the disassembly box. When the first limiting ring abuts against the side wall of the partition, the tip of the screwdriver passes through the partition and extends to the top of the operating plate. When the first limiting ring abuts against the outer side wall of the turntable, the screwdriver and the partition do not contact each other. A working hole for accommodating the screwdriver tip is opened on the partition at the same straight position corresponding to the output shaft of the disassembly motor.

[0018] This setting ensures the safety and accuracy of screwdriver operation through travel limit, preventing excessive extension that could damage parts or excessive retraction that could affect disassembly, while also providing sufficient space for the rotary dial to switch screwdrivers.

[0019] According to the technical solution provided by the embodiments of the present application, a slider is slidably connected to the top surface of the horizontal section of the L-shaped plate, the disassembly motor is fixedly connected to the slider, an electric push rod is fixedly installed on the side wall of the vertical section of the L-shaped plate away from the slider, the telescopic rod of the electric push rod horizontally penetrates the vertical section of the L-shaped plate and the rod end is fixedly connected to the slider. When the slider is pulled by the electric push rod to the position closest to the vertical section of the L-shaped plate, the second limit ring abuts against the inner side wall of the disassembly box, the tool bit of the screwdriver does not pass through the working hole of the partition plate, and when the first limit ring abuts against the outer side wall of the rotating disk, the magnetic attraction block is disengaged from the position of the clamping groove and a certain gap is left therebetween; when the slider is pushed by the electric push rod to the position farthest from the vertical section of the L-shaped plate, the first limit ring abuts against the partition plate, and the tool bit of the screwdriver passes through the working hole of the partition plate and the distance therebetween reaches the maximum;

[0020] In this arrangement, the sliding connection structure driven by the electric push rod not only ensures the stable cooperation between the motor and the screwdriver, but also simplifies the separation operation, makes the tool changing process more convenient, and improves the operational flexibility of the device.

[0021] According to the technical solution provided by the embodiments of the present application, a rust removal assembly and a water spray assembly are further installed on the partition plate. The rust removal assembly includes a rust removal box for storing rust removal agent, and the rust removal box is communicated with a rust removal nozzle installed on the side wall of the partition plate close to the positioning assembly via a liquid spray pipe; the water spray assembly includes a water storage box installed on the side wall of the partition plate close to the positioning assembly, the top surface of the water storage box is communicated with a water inlet pipe for connecting an external water source, the side wall of the water storage box away from the partition plate is communicated with a plurality of cleaning nozzles, and the water storage box, the rust removal nozzle and the working hole are vertically distributed in sequence from top to bottom;

[0022] In this arrangement, the integrated rust removal function reduces the difficulty of non-destructive disassembly, which is particularly suitable for the disassembly of old parts and protects the integrity of the parts.

[0023] According to the technical solution provided by the embodiments of the present application, a baffle shaped like a Chinese character "匚" is fixedly connected to the edge of the top surface of the base on the side where the positioning assembly is installed, a waste discharge pipe for discharging waste liquid is communicated with the bottom surface of the base on the side where the positioning assembly is installed, and a water-permeable net for preventing disassembled parts from being discharged is fixedly connected to the pipe end of the waste discharge pipe at the top surface of the base;

[0024] In this arrangement, the environmental protection and neatness of the device are improved, waste liquid is prevented from polluting the working environment, corrosion to other components of the device is reduced, and the service life of the equipment is prolonged.

[0025] In summary, this technical solution specifically discloses a positioning and separation device for non-destructive disassembly of automotive parts, which includes a screwdriver, a hydraulic cylinder, a clamping plate, and a rust-removing nozzle. The hydraulic cylinder and clamping plate enable precise positioning and multi-angle adjustment, and the device, in conjunction with interchangeable screwdrivers of different models and a rust-removing nozzle capable of spraying rust remover, can protect the parts by removing screws and performing other operations.

[0041] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0042] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0043] Please see Figures 1-7 A positioning and separation device for non-destructive disassembly of automotive parts includes a base 1. A vertically arranged partition 11 is fixedly connected to the top surface of the base 1. A positioning component 2 and a disassembly component 3 are respectively installed on both sides of the partition 11 on the top surface of the base 1. The positioning component 2 includes a lifting plate 21 set above the base 1. An operating plate 23 is rotatably connected to the top surface of the lifting plate 21. Two opposing clamping plates 26 are slidably connected to the top surface of the operating plate 23. A bidirectional lead screw 27, which is threaded to both clamping plates 26, is rotatably engaged inside the side wall of the operating plate 23. The disassembly component 3 includes a disassembly box 31 with an opening near the partition 11 and a disassembly motor 35 with its output shaft slidably inserted into the vertical side wall of the disassembly box 31 away from the partition 11. A turntable 32 is rotatably engaged inside the open end of the disassembly box 31. Several screwdrivers 33 of different types are slidably inserted into the turntable 32. An L-shaped plate 4 for supporting the disassembly motor 35 is fixedly installed on the outer side of the vertical side wall of the disassembly box 31.

[0044] In this embodiment, as Figure 4 As shown, the positioning component 2 also includes a hydraulic cylinder 22 fixedly installed on the top surface of the base 1. The extension rod of the hydraulic cylinder 22 extends vertically upward and is fixedly connected at the center of the bottom surface of the lifting plate 21. It drives the lifting plate 21 to move up and down, thereby adjusting the height of the operating plate 23 and the fixed parts on it, so that the parts are at a suitable disassembly height with the screwdriver 33 of the disassembly component 3. A waterproof shell 211 is fixedly installed on the bottom surface of the lifting plate 21. The top surface of the operating plate 23 has two grooves for accommodating the sliding connection of two clamping plates 26. Several drainage holes are opened in the grooves to guide the waste liquid deposited in the grooves of the operating plate 23 to the top surface of the base 1.

[0045] Furthermore, such as Figure 3 and Figure 4As shown, the bottom surface of the operating plate 23 is coaxially connected to a gear 24 that is rotatably connected to the top surface of the lifting plate 21. The bottom surface of the operating plate 23 is coaxially connected to the gear 24. The bottom surface of the lifting plate 21 is fixedly installed with a rotary motor 25 inside the waterproof shell 211. The output shaft of the rotary motor 25 passes through the lifting plate 21 and is coaxially connected to another gear 24. The two gears 24 mesh with each other. The rotary motor 25 drives the gears 24 to mesh and rotate, thereby rotating the operating plate 23. This allows for the adjustment of the horizontal angle of the parts, ensuring that the part to be disassembled is precisely aligned with the screwdriver 33. The waterproof shell 211 can prevent liquids such as rust remover, machine oil, and water that may come into contact with the parts during disassembly from damaging the rotary motor 25.

[0046] Furthermore, such as Figure 4 As shown, the two clamping plates 26 are threadedly connected to the two helical segments of the bidirectional lead screw 27 with opposite helical directions. The smooth section of one end of the bidirectional lead screw 27 passes through the side wall of the operating plate 23 and is coaxially connected to a rotating wheel 28. Rotating the rotating wheel 28 can drive the bidirectional lead screw 27 to rotate synchronously, thereby causing the two clamping plates 26, which are threadedly connected to the two helical segments of the bidirectional lead screw 27, to slide in opposite directions, so as to achieve the purpose of clamping the parts.

[0047] Furthermore, such as Figure 5 As shown, the number of screwdrivers 33 is at least three and they are distributed in a ring at equal intervals, which can quickly adapt to screws of different specifications on the parts. The output shaft of the disassembly motor 35 is located on the circular trajectory where the centers of the screwdrivers 33 are located. The disassembly box 31 is equipped with a reducer 34 for driving the turntable 32 to rotate. The output shaft of the reducer 34 is coaxially connected to the center of the turntable 32 to reduce the rotation speed of the turntable 32 and increase the torque. The disassembly box 31 is also equipped with an encoder 36 and a microcontroller 37. The microcontroller 37 is connected to the reducer 34 and the encoder 36 via signal lines. The encoder 36 can monitor the rotation angle of the turntable 32 in real time to confirm the position of each screwdriver 33 and transmit the signal to the microcontroller 37. The microcontroller controls the reducer 34 to rotate the required angle to ensure that the required screwdriver 33 can be rotated to the position corresponding to the output shaft of the disassembly motor 35, so as to facilitate the precise docking of the magnetic block 351 and the screwdriver's locking slot 331.

[0048] It is important to note that, such as Figure 5 As shown, the screwdriver 33 has a snap-fit ​​groove 331 at one end inside the disassembly box 31. The output shaft of the disassembly motor 35 is fixedly connected to the shaft end inside the disassembly box 31 with a magnetic block 351 that matches the size of the snap-fit ​​groove 331, so as to realize the quick connection and separation of the disassembly motor 35 and the screwdriver 33, and facilitate the switching of the screwdriver 33 with the turntable 32. The output shaft of the disassembly motor 35 is fixedly connected to the outer side of the shaft end inside the disassembly box 31 to prevent it from slipping out, thus limiting the sliding distance of the output shaft of the disassembly motor 35 inside the disassembly box 31 and avoiding excessive sliding that could lead to unstable connection.

[0049] In this embodiment, as Figure 1 and Figure 5 As shown, a first limiting ring 332 is fixedly sleeved on the outer side wall of the disassembly box 31. When the first limiting ring 332 abuts against the partition 11, the tip of the screwdriver 33 passes through the partition 11 and extends to the top of the operating plate 23, making it convenient for the screwdriver 33 to extend to the top of the operating plate 23 to contact the parts. When the first limiting ring 332 abuts against the outer side wall of the turntable 32, the screwdriver 33 and the partition 11 do not contact each other. A working hole for accommodating the tip of the screwdriver 33 is opened on the partition 11 at the same straight position corresponding to the output shaft of the disassembly motor 35, ensuring that the screwdriver 33 can be retracted to separate from the partition 11, avoiding interference with the placement of parts or the rotation of the turntable 32.

[0050] Furthermore, such as Figure 6 As shown, a slider 41 is slidably connected to the top surface of the horizontal section of the L-shaped plate 4. A disassembly motor 35 is fixedly connected to the slider 41. An electric push rod 42 is fixedly installed on the side wall of the vertical section of the L-shaped plate 4 away from the slider 41. The telescopic rod of the electric push rod 42 horizontally passes through the vertical section of the L-shaped plate 4, and its end is fixedly connected to the slider 41. The telescopic rod of the electric push rod 42 pushes the slider 41 and the disassembly motor 35 towards or away from the disassembly box 31, causing the magnetic block 351 to be tightly connected to or separated from the screwdriver 33, facilitating the switching of the screwdriver 33. When the slider 41 is pulled by the electric push rod 42 to the position closest to the vertical section of the L-shaped plate 4, the second limiting ring 352 abuts against the inner side wall of the disassembly box 31, and the screwdriver... When the tip of the screwdriver 33 does not pass through the working hole of the partition 11, and when the first limiting ring 332 abuts against the outer wall of the turntable 32, the magnetic block 351 and the snap-fit ​​groove 331 are disengaged with a certain gap, ensuring that the magnetic block 351 and the snap-fit ​​groove 331 are separated, making it convenient to select the appropriate type of screwdriver 33 to snap-fit ​​again next time; when the slider 41 is pushed by the electric push rod 42 to the position furthest from the vertical section of the L-shaped plate 4, the first limiting ring 332 abuts against the partition 11, and at the same time, the tip of the screwdriver 33 passes through the working hole of the partition 11 and the distance between it and the partition reaches the maximum. The length of the screwdriver 33 after passing through the working hole can be controlled by the electric push rod 42, making it convenient to accurately align the parts to be disassembled.

[0051] Furthermore, such as Figure 2 and Figure 7As shown, a rust removal component 5 and a water spray component 6 are also installed on the partition 11. The rust removal component 5 includes a rust removal box 51 for storing rust remover. The rust removal box 51 is connected to a rust removal nozzle 53 installed on the side wall of the partition 11 near the positioning component 2 via a spray pipe 52. The water spray component 6 includes a water storage box 61 installed on the side wall of the partition 11 near the positioning component 2. The top surface of the water storage box 61 is connected to a water inlet pipe 63 for connecting to an external water source. Several cleaning nozzles 62 are connected to the side wall of the water storage box 61 away from the partition 11. The water storage box 61, the rust removal nozzles 53, and the working holes are vertically distributed from top to bottom. First, rust remover is sprayed on the parts on the operating plate 23 to soften the rusted screws or connectors, reduce the resistance during disassembly, and avoid damage to the parts due to forced disassembly. Then, clean water is sprayed to clean the parts and the device.

[0052] It is worth mentioning that, such as Figure 2 and Figure 3 As shown, a U-shaped baffle 12 is fixedly connected to the top edge of the side where the positioning component 2 is installed on the base 1 to prevent waste liquids such as rust remover residue and engine oil from splashing out during disassembly. A waste drain pipe 13 for discharging waste liquid is connected to the bottom surface of the side where the positioning component 2 is installed on the base 1, which facilitates the discharge of waste liquid generated during disassembly. A water filter is fixedly connected to the pipe end of the waste drain pipe 13 on the top surface of the base 1 to prevent the disassembled parts from being drained away. While discharging the waste liquid, the disassembled parts are retained for subsequent processing.

[0053] Finally, it should be noted that the hydraulic cylinder 22, rotating motor 25, reducer 34, disassembly motor 35, encoder 36, microcontroller 37, and other components involved in this utility model are all general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching controller and power supply, are connected by wires. The specific connection methods should refer to the working principle of this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0054] Working Principle: In this embodiment, the positioning and separation device for non-destructive disassembly of automotive parts first clamps and fixes the parts to be disassembled by the two clamping plates 26 of the operating plate 23 on the top surface of the lifting plate 21 in the positioning assembly 2. The hydraulic cylinder 22 can drive the lifting plate 21 to adjust the height of the parts. The rotating motor 25 drives the operating plate 23 to rotate through the meshing gear 24 to adjust the angle. In the disassembly assembly 3, the turntable 32 rotates slowly with the assistance of the reducer 34 to select the required type of screwdriver 33 from several screwdrivers 33. The disassembly motor 35 rotates in an L-shaped manner. Supported by plate 4, the magnetic block 351 of its output shaft can cooperate with the corresponding screwdriver 33's snap-fit ​​groove 331. Under the action of electric push rod 42, slider 41 pushes disassembly motor 35 to bring screwdriver 33 close to the parts, thereby achieving precise and non-destructive disassembly of the parts. At the same time, rust removal box 51 can spray rust remover on the parts through rust removal nozzle 53 to prevent old parts from being damaged by the rotation of screwdriver 33 after rusting. Then, the parts and device are cleaned through water storage box 61 and cleaning nozzle 62. Baffle 12 prevents waste liquid from splashing, and waste liquid is discharged through waste pipe 13.
