Description

Technical Field

[0001] This utility model relates to the field of hardware processing technology, and in particular to a tool for disassembling and assembling hardware housings. Background Technology

[0002] Hardware housings, due to their excellent heat dissipation and stable mechanical structure, are widely used in fiber optic transceivers, switches, and various electrical enclosures, distribution boxes, and other equipment. To meet the needs of different application scenarios, hardware housings are typically equipped with various surface treatment processes, such as spray painting and powder coating. Among these, the surface treatment process of spraying the upper and lower rails together is widely used to ensure good overlap conductivity between the upper and lower covers, thereby meeting electrical performance and electromagnetic interference (EMC) requirements. However, this combined spraying process also brings significant problems in practical applications, especially in the separation of the upper and lower covers. Due to the interference bubble point between the upper and lower covers and the formation of paint accumulation during the spraying process, the bonding force between the upper and lower covers is significantly enhanced, making separation extremely difficult.

[0003] Currently, the disassembly of metal casings after painting primarily relies on traditional manual methods, such as hammering or prying open with pry bars. While these methods are simple, they have several drawbacks. First, the disassembly process is difficult, requiring strenuous work for workers and resulting in low efficiency, making it unsuitable for large-scale production. Second, forceful disassembly can easily deform the casing or scratch its surface, leading to structural or aesthetic defects and further increasing the risk of rework. Furthermore, the rate of defects caused by improper disassembly is relatively high, typically requiring a series of rework operations such as grinding, repainting, and drying. This not only wastes materials and labor costs but may also render the casing unusable due to severe deformation. These problems not only affect production efficiency and product quality but also indirectly exacerbate the environmental pollution caused by the painting process, hindering the sustainable development of industrial production.

[0004] Therefore, developing a specialized tool capable of efficiently and reliably disassembling and remanufacturing metal casings after spraying has become an urgent technical challenge. This tool must ensure disassembly efficiency while preventing casing deformation and surface damage, thereby improving turnaround time, reducing material waste and environmental pollution, and providing more reliable technical support for the disassembly and remanufacturing of metal casings. Summary of the Invention

[0005] This invention addresses the problems of difficulty, low efficiency, and easy deformation and surface damage in the disassembly of metal casings after spraying in existing technologies. It proposes a dedicated tool for disassembling and assembling metal casings after spraying. The tool uses negative pressure to adhere the casing to be disassembled and utilizes the inertial force generated by the ejector assembly to achieve efficient disassembly, thereby significantly improving work efficiency and first-pass yield.

[0006] To achieve the above objectives, this utility model is implemented according to the following technical solution:

[0007] This utility model provides a tool for disassembling and reassembling metal casings, comprising a casing fixing component, a connecting component, a ejection component, and a triggering mechanism. The casing fixing component detachably fixes the casing to be disassembled. One end of the connecting component is connected to the part of the casing to be disassembled, and the other end is connected to the ejection component. The triggering mechanism is mounted on the ejection component and controls its ejection. The casing fixing component stably fixes the casing to be disassembled, preventing displacement or deformation during disassembly. The connecting component transmits the force generated by the ejection component to the casing. The ejection component generates the required disassembly force. The triggering mechanism controls the activation and release of the ejection component.

[0008] The housing fixing assembly includes a base, a base air passage, a side plate, a side plate air passage, a suction cup, and a solenoid valve. The base air passage is located inside the base. One side plate is vertically fixed to the upper surface of the base. The side plate air passage is located inside the side plate. Multiple through holes are provided on the base and side plate at the locations of the base air passage and side plate air passage. Each through hole is fitted with a suction cup. The base air passage and side plate air passage are connected to a negative pressure device via the solenoid valve. The lower end and side of the housing to be disassembled are adhered to the base and side plate by the suction cup. When the solenoid valve is opened, the negative pressure device applies negative pressure to the suction cup through the base air passage and side plate air passage, causing the suction cup to firmly adhere to the housing to be disassembled, thereby fixing it between the base and the side plate. The suction cup is made of silicone material to ensure good sealing and durability, while avoiding damage to the surface of the housing to be disassembled.

[0009] The ejection assembly includes a sleeve, a sliding hammer, and a compression spring. The sleeve is a cylindrical hollow structure that houses the sliding hammer and allows it to move up and down. The sliding hammer is located inside the sleeve and is movable. A limiting outer flange is provided at the lower end of the sliding hammer, and a limiting inner flange is provided at the upper end of the sleeve; both together limit the range of motion of the sliding hammer. The upper end of the sliding hammer passes through the upper end of the sleeve and is located outside the sleeve. The lower end of the sleeve is connected to one end of the connecting assembly. The compression spring is located between the lower end of the sliding hammer and the lower end inside the sleeve. The triggering mechanism is located between one side of the sliding hammer and the side wall of the sleeve. This mechanism stores elastic potential energy. When the sliding hammer is pressed to its lower limit, the compression spring is compressed, and the stored elastic potential energy, when released, propels the sliding hammer to move rapidly upward. Furthermore, the upper end of the sliding hammer passes through the upper end of the sleeve and extends to the outside, allowing for manual pressing by the operator. In addition, the contact surface between the outer limiting flange and the inner limiting flange is hardened to improve durability and impact resistance.

[0010] The triggering mechanism includes a button latch and a sliding hammer latch. The sliding hammer latch is disposed on the outer wall of the sliding hammer, and the button latch is disposed on the side wall of the sleeve. The sliding hammer latch and the button latch are engaged. This engagement locks and releases the sliding hammer. When the sliding hammer is pressed to its lower limit, the sliding hammer latch engages with the button latch, keeping the sliding hammer locked. When the button latch is pressed down, the sliding hammer latch disengages from the button latch, and the sliding hammer springs upward rapidly under the force of the compression spring. Notably, the button latch employs a dual-stage unlocking design; a certain pre-pressure is required during pressing to trigger the unlocking action, effectively preventing accidental operation.

[0011] The connecting assembly consists of multiple disassembly heads of different specifications. The lower end of the sleeve is detachably connected to the upper end of one of the disassembly heads, and the lower end of the disassembly head is connected to the disassembly portion of the housing to be disassembled. The design of the disassembly head is based on the specific structural characteristics of the housing to be disassembled, such as the differences in the fastening depth, width, and shape of different housing models. By replacing the disassembly head with different specifications, diverse needs can be met.

[0012] The working principle of this utility model is as follows:

[0013] S1, place the housing to be disassembled between the base and the side plate, start the solenoid valve to connect the negative pressure device, and use the suction cup to adsorb and fix the housing to be disassembled;

[0014] S2. Select a suitable disassembly head according to the structure of the machine housing to be disassembled, connect one end of the head to the lower end of the sleeve, and lock the other end in the disassembly position of the machine housing to be disassembled.

[0015] S3, manually press the sliding hammer to move it downwards and compress the compression spring until the sliding hammer block engages with the button latch;

[0016] S4, press the button latch to disengage the sliding hammer latch from the button latch, and the sliding hammer will quickly spring upward under the force of the compressed spring;

[0017] S5, the outer limiting flange of the sliding hammer collides with the inner limiting flange of the sleeve, generating an upward inertial force, which acts on the housing to be disassembled through the disassembly head, completing the disassembly. If disassembly fails on the first attempt, the above steps can be repeated until disassembly is completed.

[0018] The beneficial effects of this utility model are:

[0019] The synergistic effect of the negative pressure adsorption system and the ejector assembly enables highly efficient disassembly of metal casings after spraying. First, the negative pressure adsorption system firmly secures the casing to be disassembled using suction cups, avoiding disassembly failures caused by casing movement in traditional methods and improving process stability. Second, the ejector assembly stores energy through a compressed spring and releases it upon triggering, providing a strong instantaneous inertial force for the disassembly process, significantly improving efficiency. In particular, the multi-specification disassembly head design of the ejector assembly makes this tool suitable for disassembling casings of different structures, expanding its application range. Furthermore, the new disassembly method avoids situations where severely deformed casings cannot be reused for spraying, saving material and labor costs while reducing environmental pollution caused by spraying, thus contributing to the sustainable development of industrialization.

[0020] In summary, this utility model provides a highly efficient, stable, and environmentally friendly tool for disassembling and assembling metal casings through specific technical implementation methods. It is suitable for disassembling and assembling various metal casings after spraying and assembling, and has high practicality and widespread applicability. Attached Figure Description

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0029] This utility model provides a tool for disassembling and reassembling metal casings. It uses a negative pressure adsorption system to fix the casing to be disassembled and utilizes a catapult assembly to provide instantaneous inertial force to complete the disassembly. The following is in conjunction with the attached... Figure 1 To be continued Figure 5 The specific embodiments of this utility model are described in detail with reference to the component numbers marked in the accompanying drawings.

[0030] This metal casing disassembly and assembly tool mainly consists of a casing fixing component, a connecting component, an ejection component, and a triggering mechanism. The casing fixing component, used to firmly adhere the casing to be disassembled, includes a base 1, side plates 3, suction cups 5, and a negative pressure adsorption system. The base 1 and side plates 3 are respectively equipped with base air channels 2 and side plate air channels 4, through which suction cups 5 are installed. The base air channels 2 and side plate air channels 4 are connected to a negative pressure device via solenoid valves 6 to achieve negative pressure adsorption. The number and distribution of suction cups 5 are designed according to the size and shape of the casing 13 to be disassembled, ensuring uniform force during adsorption and avoiding localized stress concentration that could damage the casing surface. For example, when the casing 13 is rectangular, the suction cups 5 are distributed at the four corners and the central area of ​​the rectangle, forming a stable adsorption support surface; while when the casing 13 is irregularly shaped, the suction cups 5 are flexibly arranged according to the edge contour of the casing, ensuring sufficient adsorption force at each critical point.

[0031] The connecting assembly, which connects the ejection assembly to the disassembly portion of the housing 13 to be disassembled, includes multiple disassembly heads 12 of different specifications. One end of each disassembly head 12 is detachably connected to the lower end of the sleeve 7 of the ejection assembly, and the other end engages with the disassembly portion of the housing 13 to be disassembled. The design of the disassembly head 12 is based on the specific structural features of the housing 13 to be disassembled, such as the differences in the snap-fit ​​depth, width, and shape of different housing models. Different specifications of disassembly heads 12 are used to meet diverse needs. In particular, the engaging end of the disassembly head 12 can be provided with anti-slip teeth to enhance the bonding strength with the housing 13 to be disassembled and prevent slippage during ejection. Furthermore, the connection between the disassembly head 12 and the sleeve 7 uses a threaded fit or a quick-release mechanism, facilitating rapid replacement and adjustment by the operator. For example, when switching from one housing model to another, the operator only needs to rotate the disassembly head 12 to complete the replacement, with the entire process taking no more than 10 seconds.

[0032] The ejection assembly, used to generate instantaneous inertial force, includes a sleeve 7, a sliding hammer 8, and a compression spring 9. The sliding hammer 8 is located within the sleeve 7 and can move up and down. The lower end of the sliding hammer 8 has a limiting outer flange, and the upper end of the sleeve 7 has a limiting inner flange. The compression spring 9 is located between the lower ends of the sliding hammer 8 and the sleeve 7, storing and releasing the energy required for ejection. The trajectory of the sliding hammer 8 is limited by a guide groove on the inner wall of the sleeve 7, ensuring it maintains linear motion during pressing and ejection, avoiding energy loss or mechanical failure due to deviation. The contact surface between the limiting outer flange and the limiting inner flange is hardened to improve durability and impact resistance. The elastic coefficient of the compression spring 9 is matched according to the disassembly difficulty of the housing 13 to be disassembled, ensuring sufficient and controllable ejection force. For example, when the overlap interference of the housing 13 to be disassembled is large, a compression spring 9 with a high elastic coefficient is selected; conversely, a compression spring 9 with a low elastic coefficient is selected, thus adapting to the disassembly requirements of different housings.

[0033] The triggering mechanism controls the locking and releasing of the sliding hammer 8, and includes a button latch 10 and a sliding hammer latch 11. The sliding hammer latch 11 is located on the outer wall of the sliding hammer 8, and the button latch 10 is located on the side wall of the sleeve 7. The sliding hammer latch 11 and the button latch 10 are engaged. By pressing the button latch 10, the sliding hammer latch 11 is disengaged from the button latch 10, thereby releasing the sliding hammer 8. The button latch 10 adopts a two-stage unlocking design. A certain pre-pressure needs to be applied during the pressing process to trigger the unlocking action, effectively preventing accidental operation. For example, if the operator accidentally touches the button latch 10, the button latch 10 will not trigger unlocking because the pre-pressure value has not been reached, thus avoiding the risk of accidental activation.

[0034] The working principle of this hardware housing assembly and disassembly tool is as follows:

[0035] S1 secures the casing to be disassembled. The negative pressure device is activated via solenoid valve 6, creating negative pressure on the suction cups 5 on the base 1 and side plate 3. This firmly adheres the casing 13 to the base 1 and side plate 3, ensuring stability during disassembly. The pressure value of the negative pressure adsorption system can be adjusted according to the material and weight of the casing 13 to achieve optimal adsorption. For example, a lower negative pressure value is sufficient for stable adsorption on a lighter aluminum alloy casing, while a higher negative pressure value is needed for a heavier stainless steel casing to ensure a firm adsorption.

[0036] S2 Selects and installs the disassembly head 12. Based on the specific structure of the housing 13 to be disassembled, selects a suitable disassembly head 12, connecting one end to the lower end of the sleeve 7, and locking the other end into the disassembly section of the housing 13. The installation of the disassembly head 12 is achieved through a threaded connection or quick-release mechanism, facilitating rapid replacement and adjustment. For example, when the latching depth of the housing 13 to be disassembled is 5 mm, a disassembly head 12 with a length of 5 mm is selected; when the latching depth is 8 mm, a disassembly head 12 with a length of 8 mm is selected, thus ensuring that the disassembly head 12 can accurately engage with the latching position.

[0037] S3 Press the sliding hammer 8. Manually press the sliding hammer 8 to move it downwards and compress the compression spring 9 until the sliding hammer latch 11 engages with the button latch 10, locking the sliding hammer 8. During this process, the elastic coefficient of the compression spring 9 is matched according to the disassembly difficulty of the housing 13 to be disassembled, to ensure sufficient and controllable ejection force. For example, when the overlap interference of the housing 13 to be disassembled is large, a compression spring 9 with a high elastic coefficient is selected; conversely, a compression spring 9 with a low elastic coefficient is selected, thus adapting to the disassembly requirements of different housings.

[0038] S4 triggers the ejection. Pressing the button latch 10 disengages the sliding hammer latch 11 from the button latch 10; the sliding hammer 8 is rapidly ejected upwards under the force of the compression spring 9 until the limiting outer flange of the sliding hammer 8 contacts and collides with the limiting inner flange of the sleeve 7; during the ejection process, the sliding hammer 8 applies an upward inertial force to the sleeve 7, which is transmitted to the housing 13 to be disassembled through the disassembly head 12, generating an upward inertial pull, thereby completing the disassembly of the housing. The magnitude of the inertial force during the ejection process can be precisely controlled by adjusting the initial compression of the compression spring 9 to adapt to the disassembly requirements of different housings. For example, when the overlap interference of the housing 13 to be disassembled is large, the initial compression of the compression spring 9 is increased to increase the ejection force; conversely, the initial compression is reduced, thereby achieving precise adjustment of the ejection force.

[0039] S5 repeat operation. If disassembly fails on the first attempt, press the sliding hammer 8 repeatedly to trigger the ejection until disassembly is complete.

[0040] The practical application scenario of this hardware housing disassembly and assembly tool is as follows: On a fiber optic transceiver production line, a batch of aluminum alloy housings with upper and lower rails using the combined spraying process needs to be disassembled. First, the housing 13 to be disassembled is placed between the base 1 and the side plate 3. The negative pressure device is activated by the solenoid valve 6, causing the suction cup 5 to generate negative pressure, firmly adhering the housing to the base 1 and side plate 3. Then, a suitable disassembly head 12 is selected based on the housing's locking depth and installed at the lower end of the sleeve 7. The snap-fit ​​end of the disassembly head 12 is accurately inserted into the housing's locking position. Next, the sliding hammer 8 is manually pressed, compressing the compression spring 9. Simultaneously, the sliding hammer latch 11 engages with the button latch 10, locking the sliding hammer 8. Finally, the button latch 10 is pressed, triggering the ejection action of the sliding hammer 8. The inertial pulling force generated by the disassembly head 12 separates the upper and lower covers of the housing. If the housing is not completely disassembled in one ejection, the above operation is repeated until the disassembly task is completed. The entire disassembly and assembly process takes less than 30 seconds, significantly improving work efficiency.

[0041] The advantage of this metal casing disassembly and assembly tool lies in its efficient disassembly after spraying, achieved through the synergistic effect of a negative pressure adsorption system and an ejector assembly. The negative pressure adsorption system firmly secures the casing 13 to be disassembled using suction cups 5, avoiding disassembly failures caused by casing movement in traditional methods and improving process stability. The ejector assembly stores energy through a compression spring 9 and releases it upon triggering, providing a strong instantaneous inertial force for the disassembly process, significantly improving efficiency. The multi-specification disassembly head 12 design of the ejector assembly makes the tool suitable for disassembling casings of different structures, expanding its application range. This new disassembly method avoids situations where severely deformed casings cannot be reused for spraying, saving material and labor costs while reducing environmental pollution caused by spraying, thus contributing to the sustainable development of industrialization.

[0042] In summary, this utility model provides a highly efficient, stable, and environmentally friendly tool for disassembling and assembling metal casings through specific technical implementation methods. It is suitable for disassembling and assembling various metal casings after spraying and assembling, and has high practicality and widespread applicability.
