Description

Technical Field

[0001] This invention belongs to the field of mobile phone disassembly technology and relates to an auxiliary fixture for mobile phone disassembly. Background Technology

[0002] With technological advancements and improved living standards, the global smartphone industry is booming, with mobile phone upgrades accelerating rapidly. In 2019, global smartphone shipments reached 1.39 billion units, of which my country accounted for 370 million units. Along with the rapid increase in shipments, the number of discarded mobile phones each year has also risen sharply, reaching 499 million units in 2019. It is projected that this number will increase to 524 million units after the commercialization of 5G technology. The negative impacts of discarded mobile phones mainly include environmental pollution and resource waste. Untreated toxic and harmful metals in mobile phones can severely pollute soil and water resources, endangering human health and causing irreversible damage to the ecological environment. At the same time, mobile phones contain high-value materials, such as gold, silver, copper, and rare metals, which can be recycled and reused, significantly reducing raw material and production costs. Therefore, the dismantling and recycling of discarded mobile phones has economic, social, and environmental benefits, and is of great significance to promoting the sustainable development of my country's manufacturing industry.

[0003] Currently, most small workshops in China use manual crushing methods, dismantling only usable parts from discarded mobile phones, while other materials are directly incinerated or landfilled. Some legitimate companies manually dismantle discarded mobile phones and then use mechanical crushing and sorting equipment to recycle materials. At present, most dismantling processes in the recycling of used mobile phones are done manually, without mechanization or automation. Existing technologies include designing dismantling workbenches to provide workers with a good dismantling environment (CN107855998A), using lifting and moving devices to move dismantling tools (CN107695076A), and dismantling production lines using multi-layer conveyor belts to achieve automatic feeding and classified collection of dismantled products (CN205465107U). However, these technologies mainly revolve around traditional manual operations, providing a working environment to support manual dismantling. There are also technologies that target the individual recycling or repair of certain mobile phone components, mainly focusing on screen separation. Some technologies use cylinders and screen-suction components to achieve screen separation (CN104858829A), others utilize a base, phone tray, and screen top post mechanism (CN203738714U), and still others employ specialized pressure-holding clamps to assist in phone casing processing (CN206588853U). However, existing technologies do not directly address the optimization of clamping tools during the disassembly process.

[0004] Furthermore, robots are already widely used in manufacturing assembly, packaging, and logistics, showing great potential in improving product dismantling and recycling efficiency, and achieving the goals of reducing time and costs. Industrial robots, equipped with end effectors, can perform drilling, gripping, and cutting operations required in the dismantling process, enabling the disassembly and separation of target components and materials from discarded mobile phones. However, how to fix the discarded mobile phones to be dismantled and assist the robotic arm in completing various operations remains a pressing technical problem to be solved. Summary of the Invention

[0005] This invention provides an auxiliary clamp for mobile phone disassembly, aiming to overcome the shortcomings of existing technologies, such as long clamping time and low operating efficiency of discarded mobile phones. It provides an auxiliary device for manual or automated disassembly, utilizing a horizontal clamping mechanism and a flipping / rotating mechanism to clamp, fix, and flip discarded mobile phones, coordinating with various operations during manual or robotic arm disassembly. This invention features a simple process, high efficiency, and a reasonable and economical method.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A mobile phone disassembly auxiliary clamp includes a horizontal clamping mechanism;

[0008] The horizontal clamping mechanism includes a first baffle, a second baffle, a side clamping device, a surface clamping device, and a mobile phone support base;

[0009] The phone includes side a, side b, side c, front, and back, with side b and side c facing each other;

[0010] The first baffle is used to block the side a of the phone; the second baffle is used to block the side b of the phone; the side clamping device is used to clamp the side c of the phone; the surface clamping device is used to clamp the front or back of the phone; the phone support base is used to support the phone; generally, to achieve complete fixation of the phone, it is necessary to restrict the phone's six degrees of freedom, namely the translation and rotational degrees of freedom along the X, Y, and Z axes in space. The basic principle of the horizontal clamping mechanism is the six-point positioning principle. The phone has one and only one completely determined position within the horizontal clamping mechanism, which is called complete positioning.

[0011] As a preferred technical solution:

[0012] As described above, in a mobile phone disassembly auxiliary clamp, the first baffle and the second baffle are fixed on the mobile phone support base.

[0013] As described above, the mobile phone disassembly auxiliary clamp also includes a main support base in the horizontal clamping mechanism; the mobile phone support base is fixed on the main support base, and half of the main support base is connected to the mobile phone support base. Considering that the sizes of mobile phones from different manufacturers are not exactly the same, the half here does not necessarily have to be exactly half of the main support base, but only about half of the main support base.

[0014] As described above, the mobile phone disassembly auxiliary fixture has a plate-shaped structure for both the mobile phone support base and the main support base. Generally, the plate-shaped structure is an exploratory mechanical design scheme when processing costs are not considered. In principle, the plate-shaped structure can be replaced by sheet metal structural parts. Sheet metal parts have a simple structure, are lightweight, and are reliable in processing and forming.

[0015] The mobile phone disassembly auxiliary clamp described above includes a side clamping device comprising a power source, a push rod connector, a connecting rod, a pin, and a washer.

[0016] The power source is a first cylinder or an electric push rod. The piston rod of the first cylinder or the motor push rod of the electric push rod moves in a direction parallel to the first baffle. The selection of the actuator mainly takes into account the applicable scenarios of pneumatic, electric and hydraulic transmission. Pneumatic and electric transmissions have high precision and rapid control action, making them suitable for occasions where speed regulation requirements are not high.

[0017] The push rod connector has a rod-shaped structure, and the push rod connector is connected to the connecting rod in an L-shape.

[0018] The pin is fixed to the main support seat;

[0019] The end of the push rod connector away from the connecting rod is connected to the piston rod of the first cylinder or the motor push rod of the electric push rod; the connecting rod is rotatably engaged with the pin, and the rotatable engagement position is close to the connection end of the connecting rod and the push rod connector; the gasket faces the second baffle, is installed on the connecting rod, and is away from the connection end of the connecting rod and the push rod connector.

[0020] The clamping process of the side clamping device is as follows: the piston rod of the first cylinder or the motor push rod of the electric push rod moves in a direction parallel to the first baffle, and drives the connecting rod to move through the push rod joint. At this time, the connecting rod rotates around the pin shaft. One end of the connecting rod (the end connected to the push rod joint) moves away from the phone to be disassembled, while the other end of the connecting rod moves closer to the phone to be disassembled. Since the gasket is installed near this end, the gasket moves closer to the phone to be disassembled until the side c of the phone is clamped.

[0021] The mobile phone disassembly auxiliary clamp described above includes a cylinder connecting plate as a side clamping device; the cylinder connecting plate is fixed on the main support base; and the power source is located between the mobile phone support base and the cylinder connecting plate.

[0022] As described above, a mobile phone disassembly auxiliary clamp has a surface clamping device comprising a second cylinder and a clamping block; the second cylinder is fixedly connected to the main support base; the clamping block is located above the mobile phone support base; and the piston rod of the second cylinder is fixedly connected to the clamping block.

[0023] The mobile phone disassembly auxiliary fixture described above further includes a flipping and rotating mechanism; the flipping and rotating mechanism is used to drive the mobile phone to flip over.

[0024] The mobile phone disassembly auxiliary fixture described above includes a flipping and rotating mechanism comprising a rotary motor, a rotary shaft, a cylinder support base, a third cylinder, two grippers, and two end clamping plates.

[0025] The output shaft, rotating shaft, cylinder support, and third cylinder of the rotary motor are fixedly connected in sequence.

[0026] The third cylinder and two grippers are connected to form a pneumatic clamp;

[0027] The ends of the two grippers furthest from the third cylinder are each connected to an end clamping plate;

[0028] The flipping and rotating mechanism has two main functions. One is to clamp the phone to be disassembled, which is mainly achieved through the cooperation of the third cylinder, the gripper, and the end clamping plate. One end of the gripper is mounted on the actuating rod and guide rail of the third cylinder, and the other end is firmly connected to the end clamping plate. The piston inside the third cylinder drives the main shaft and the actuating rod to move under the pressure of air, which can realize the relative movement of the actuating rod and ultimately the relative movement of the end clamping plate. The other function is to flip the phone to be disassembled. Since the rotary motor is fixedly connected to other components, the rotation of the rotary motor can ultimately realize the flipping movement of the phone to be disassembled held by the end clamping plate.

[0029] The mobile phone disassembly auxiliary clamp described above includes a flipping and rotating mechanism that further includes a rotary motor support base; the rotary motor is fixed on the rotary motor support base.

[0030] Furthermore, the mobile phone disassembly auxiliary clamp of the present invention may also include a PLC control box and a contact sensor; the contact sensor is installed on the mobile phone support base and is connected to the PLC control box via signal. The mobile phone to be disassembled is placed on the horizontal clamping mechanism by manual or automatic unloading. After the contact sensor on the horizontal clamping mechanism obtains the gravity signal, it can indirectly control the first cylinder or electric push rod and the second cylinder on the horizontal clamping mechanism to perform actions through the PLC control box, thereby clamping the mobile phone; the PLC control box is connected to the first cylinder or electric push rod and the second cylinder to control the horizontal clamping mechanism to release or clamp the mobile phone; the PLC control box is connected to the third cylinder to control the opening or closing of the gripper of the flipping and rotating mechanism; the PLC control box is connected to the rotary motor to control the flipping and rotating mechanism to drive the mobile phone to rotate 180 degrees.

[0031] Beneficial effects:

[0032] (1) The mobile phone disassembly auxiliary clamp of the present invention can quickly, accurately and easily complete the clamping, reduce the clamping time in the disassembly process and improve the disassembly efficiency;

[0033] (2) This invention can be applied to waste mobile phones of different brands and models, improves the standardization and mechanization of clamping during disassembly, and reduces the loss of parts and materials due to improper clamping in traditional methods.

[0034] (3) This invention not only supports manual disassembly, but is also applicable to the operation and coordination with robotic arms during automated disassembly, providing strong support for the automation upgrade of disassembly and recycling. Attached Figure Description

[0047] The side clamping device includes a cylinder connecting plate 5, a power source, a push rod connector 7, a connecting rod 8, a pin, and a washer 9. The cylinder connecting plate 5 is fixed on the main support base 4. The power source is located between the mobile phone support base 2 and the cylinder connecting plate 5. The power source is a first cylinder 6 or an electric push rod. The piston rod of the first cylinder 6 or the motor push rod of the electric push rod moves in a direction parallel to the first baffle 3. The push rod connector 7 is a rod-shaped structure, and the push rod connector 7 is connected to the connecting rod 8 in an L-shape. The pin is fixed on the main support base 4.

[0050] Figures 4-6 This embodiment describes the process of a flipping and rotating mechanism rotating a mobile phone while the horizontal clamping mechanism holds the mobile phone 1 to be disassembled. Figure 4 This is a diagram illustrating how a mobile phone is held in place during disassembly. Figures 5-6 This is a diagram illustrating the flipping and rotating of the phone to be disassembled. The main steps are as follows:

[0051] (1) When the mobile phone 1 to be disassembled needs to be flipped, the horizontal clamping mechanism clamps the mobile phone 1 to be disassembled and transports it to the flipping waiting position by the conveying device. Then the rotary motor 13 of the flipping rotation mechanism rotates to make the end clamping plate 19 horizontal, and the third cylinder 17 pushes the jaw 18 to open, so that a clamping space is generated between the two end clamping plates 19. This position is recorded as the flipping clamping position.

[0052] (2) The horizontal clamping mechanism moves from the flipping waiting position to the flipping clamping position. At this time, the reversing piston in the third cylinder 17 moves to drive the gripper 18 to perform a closing motion until the two end clamping plates 19 clamp the mobile phone 1 to be disassembled. Figure 4 As shown;

[0053] (3) When the flipping and rotating mechanism is fixed to the mobile phone 1 to be disassembled, the first cylinder 6 (or electric push rod) and the second cylinder 10 in the horizontal clamping mechanism make a return motion, so that the connecting rod 8 and the clamping block 11 are released, and the horizontal clamping mechanism is transported to the flipping waiting position under the drive of the conveying device.

[0054] (4) At this time, the mobile phone 1 to be disassembled is flipped and rotated, and the rotating motor 13 rotates 180 degrees and holds.

[0055] (5) When the mobile phone 1 to be disassembled is flipped over, the horizontal clamping mechanism is transported to the flipping clamping position under the action of the conveying mechanism. The first cylinder 6 (or electric push rod) and the second cylinder 10 make a feeding movement to re-clamp the mobile phone 1 to be disassembled. Then the reversing piston in the third cylinder 17 drives the jaw 18 to open, and the clamping space is re-formed.

[0056] (6) The mobile phone 1 to be disassembled on the horizontal clamping mechanism is now in the flipped state. It will then be transported to other processing stations according to processing needs. If it needs to be flipped again, the above steps will be repeated.
