Description

Technical Field

[0001] This invention relates to the field of automatic splitting equipment technology, and in particular to a device for separating the upper and lower casings of waste electricity meters. Background Technology

[0002] With the continuous advancement of smart grid construction and the accelerated pace of electricity meter replacement, a large number of obsolete electricity meters are being centrally recycled and processed. Electricity meters typically consist of an upper and lower casing tightly connected by clips, screws, or ultrasonic welding, and contain recyclable resources such as metal terminals, circuit boards, and metering modules. During the resource recycling process, the upper and lower casings must first be effectively separated to allow for the classification, disassembly, and material recovery of the internal components.

[0003] At present, the separation of the casing of waste electricity meters mainly relies on manual operation, such as using screwdrivers, pry bars and other tools to forcibly pry it open, which has the following prominent problems: (1) Low efficiency: manual disassembly is slow and it is difficult to meet the needs of large-scale recycling and processing; (2) Poor safety: hands are easily scratched during operation, and improper force may cause short circuits of internal live parts or discharge of residual capacitors, which poses safety hazards; (3) Weak adaptability: the structure of electricity meters of different brands and models varies greatly, and it is difficult to standardize manual operation, resulting in low automation. Summary of the Invention

[0004] The present invention provides a device for separating the upper and lower casings of waste electricity meters, so as to at least solve one of the above-mentioned technical problems.

[0005] To solve the above-mentioned technical problems, one or more embodiments of the present invention provide a waste electricity meter upper and lower shell separation device, including a base frame, a feeding conveyor line, a transfer and positioning component, a whole meter feeding component, a cutting execution mechanism, a lifting and protection component, and an upper shell picking component.

[0006] The feeding conveyor line is used to transport used electricity meters along a first direction. The feeding conveyor line is supported by a base frame. The width direction of the feeding conveyor line is a second direction. A lifting and lowering blocking and positioning component is provided in the middle of the feeding conveyor line to intercept, position, and lift the electricity meters. A transfer and positioning component is located on one side of the feeding conveyor line along the second direction. It can support and position the electricity meters transferred from the feeding conveyor line. The meter loading assembly can grab and transfer the electricity meter from the blocking positioning assembly to the transfer positioning assembly, or transfer the electricity meter from the transfer positioning assembly to the blocking positioning assembly; the cutting execution mechanism is located above the transfer positioning assembly, and includes a horizontal motion assembly and a vertical cutting assembly mounted thereon; the vertical cutting assembly, driven by the horizontal motion assembly, can move along a first direction and a second direction, and the cutter of the vertical cutting assembly can be raised and lowered vertically so that the cutter can cut around the seam between the upper and lower shells of the electricity meter; the lifting protection assembly is located between the loading conveyor line and the transfer positioning assembly, and the lifting protection assembly includes at least a door panel that can be raised and lowered to connect or separate the space between the loading conveyor line and the transfer positioning assembly; the upper shell picking assembly is located at the end of the loading conveyor line to pick up the separated upper shell from the electricity meter.

[0007] Furthermore, the transfer positioning assembly includes a base plate, a transfer cylinder, and a meter clamping and positioning assembly driven by the transfer cylinder; the meter clamping and positioning assembly includes a lower mounting plate, a side clamping mechanism disposed on the lower mounting plate, and an upper pressing mechanism; the side clamping mechanism includes a side clamping cylinder and a side clamping plate driven therefrom, for clamping the energy meter from the side; the upper pressing mechanism includes a pressing cylinder and a pressing rod driven therefrom, for pressing the energy meter from above.

[0008] Furthermore, the meter clamping and positioning assembly also includes a lifting limit block for limiting different models of electricity meters. The lifting limit block is located in the middle of the lower mounting plate and can be lifted vertically.

[0009] The beneficial effects of one or more of the above technical solutions are as follows: (1) This invention integrates a feeding conveyor line, a meter feeding assembly, a transfer and positioning assembly, a cutting actuator, and a casing removal assembly to construct a complete automated production line. This changes the traditional manual prying and dismantling operation mode and realizes fully automated operation of the electricity meter from feeding, positioning, cutting and separation to casing removal. This device can operate continuously, greatly increasing the processing capacity per unit time, effectively meeting the efficiency requirements of large-scale waste electricity meter recycling and processing, and also significantly reducing the labor intensity of operators.

[0010] (2) The present invention designs a lifting and protective assembly, whose door panel descends during cutting operations to form a separated working space. This design effectively isolates the operator from the high-speed moving cutting components, fundamentally avoiding the risk of mechanical injury. At the same time, the separated environment also suppresses the splashing of debris that may be generated during cutting, helps to keep the working environment clean, and prevents the spread of harmful dust, making it more environmentally friendly.

[0011] (3) To address the differences in size and connection methods (such as clips, screws, welding) among different brands and models of electricity meters, the transfer positioning component of this device is equipped with an adjustable meter clamping positioning component. The cutting actuator consists of a precision horizontal motion component and a vertical cutting component, which can accurately control the path and depth of the cutter, thereby adaptively aligning and separating various types of upper and lower shell seams. This adaptability reduces the need for frequent replacement of special tooling for different specifications of electricity meters, and enhances the versatility and production efficiency of the equipment.

[0012] (4) Unlike traditional methods of manual prying or complete crushing, this device uses controlled mechanical cutting. The cutting actuator can make precise cuts along the seams, minimizing damage to the upper and lower shells and internal precision components (such as circuit boards and metering modules). This ensures the integrity of the shell material and avoids damage to valuable internal components, thereby improving the value and efficiency of resource recycling. Attached Figure Description

[0044] In this embodiment, the cutting actuator is configured such that the horizontal motion component drives the vertical cutting component to move along a direction parallel to the joint seam between the upper and lower shells of the energy meter, while the cutting tool of the vertical cutting component performs rotational cutting to complete the separation of the upper and lower shells.

[0045] Working principle: The scrap meter flows from the feeding conveyor line 13 to the blocking positioning component 4. After the photoelectric detection component 11 detects that the scrap meter is in place, the lifting cylinder 46 drives the lifting base plate 41 to lift the scrap meter. In the meter feeding component 3, the sliding cylinder 39 drives the pneumatic gripper cylinder 319 to descend. After it is in place, the gripper plate 317 and the polyurethane pad 318 clamp the scrap meter, and the sliding cylinder 39 rises to its position. The rodless feeding cylinder 33 extends to send the workpiece above the transfer positioning component 8. The sliding cylinder 39 descends to place the scrap meter on the meter clamping positioning component 85. The sliding cylinder 39 rises, and the rodless feeding cylinder 33 returns to its position. The guide rod type rodless cylinder 72 drives the door plate 74 to descend, and the door closes.

[0046] The side clamping cylinder 8514 of the meter clamping and positioning assembly 85 drives the side clamping plate 8515 and the side clamping polyurethane block 8516 to clamp the scrapped meter from the side. The pressing cylinder 8515 drives the pressing rod 8512 to press the meter from above. The transfer cylinder 82 drives the meter clamping and positioning assembly 85 to reach the meter cutting position.

[0047] The horizontal motion assembly 5 and the vertical cutting assembly 6, through the servo motor 511, the Y-axis motion assembly 515, and the brake servo motor 66, jointly start the cutting spindle assembly 614 to complete the cutting and separation of the upper casing of the scrapped table. During the cutting process, the chip collection box 16 is activated to collect the chips in the chip receiving tray 15.

[0048] The transfer positioning component 8 transports the scrapped form out, the lifting and protection component 7 opens the door, the form loading component 3 removes the scrapped form and places it at the blocking positioning component 4, the lifting cylinder 46 descends, and the blocking cylinder 42 descends. The scrapped form continues to flow along the loading conveyor line to the upper shell picking component 9, and the rotary cylinder 918 selects whether to rotate depending on whether the scrapped form is single-phase or three-phase. The slide cylinder 98 drives the extended pneumatic gripper cylinder 920 to descend. After reaching the position, the gripper plate 922 and the polyurethane pad 922 clamp the upper shell of the scrapped form, and the slide cylinder 98 rises to the position. The horizontal moving rodless cylinder 95 extends to send the workpiece above the upper shell unloading conveyor line 10, the slide cylinder 98 descends to place the upper shell of the scrapped form on the upper shell unloading conveyor 10, the slide cylinder 98 rises, the horizontal moving rodless cylinder 95 returns to the position, and the bottom shell of the scrapped form and the PCBA board flow to the next station.
