Description

Technical Field

[0001] This utility model relates to the technical field of mobile power bank manufacturing, and in particular to a mobile power bank casing pressing device. Background Technology

[0002] With the rapid development of the power bank industry, consumers are increasingly demanding thinner, lighter, and more multifunctional products. This places higher demands on the assembly precision of power bank casings. The casing pressing must ensure a smooth, scratch-free surface and tight seams, while also taking into account production efficiency to meet the needs of large-scale manufacturing.

[0003] Currently, there are two main traditional methods for pressing the casing of power banks. One is manual pressing, which relies on operators to manually apply pressure to fasten the casing. This method has significant drawbacks: firstly, prolonged operation can easily lead to employee fatigue, resulting in uneven pressing force, incomplete pressing, large gaps, and poor product consistency; secondly, the pressing time for a single piece is long, resulting in extremely low production efficiency and making it unsuitable for mass production. The other method uses a simple pneumatic pressing device, employing a single pneumatic unit for pressing a single product. While this method solves the problem of uneven pressure in manual pressing, the equipment purchase cost is high, and multiple corresponding devices are required if multiple models of power banks need to be produced; secondly, equipment management and maintenance are difficult, as multiple devices need to be individually debugged and repaired, consuming more manpower and space resources; thirdly, the flexibility of adjusting pressing parameters (such as pressure and time) is poor, making it impossible to accurately adapt to casings of different thicknesses and materials, easily leading to casing deformation or scratches. Utility Model Content

[0004] This utility model aims to at least partially solve one of the problems in related technologies. Therefore, one of the objectives of this utility model is to provide a mobile power bank casing pressing device for achieving multi-station synchronous pressing, improving production efficiency, ensuring uniform pressing pressure and controllable time, and enhancing product consistency.

The pressing mechanism includes a plurality of independent pneumatic pressing units, each pneumatic pressing unit corresponding to one of the pressing acupoints, and each pneumatic pressing unit provides controllable downward pressure.

[0006] Furthermore, each of the aforementioned acupoints is equipped with a pressure head, which is made of silicone.

[0007] Furthermore, the pressure head has a partitioned design, which includes a central clearance zone and an edge pressing zone. The clearance zone is used to avoid the battery, and the pressing zone is used to press the edge of the outer casing.

[0009] Furthermore, each of the pneumatic pressing units includes a cylinder, a connecting rod, and a pressure plate.

[0011] Furthermore, the pneumatic pressing unit also includes a guide rod, one end of which is fixedly connected to the base and the other end is movably connected to the pressure plate.

[0012] Furthermore, the system also includes a control system electrically connected to the pressing mechanism for receiving signals and sending control commands. The control system individually adjusts and controls the downward pressure and pressing time of each pneumatic pressing unit.

[0013] Furthermore, each of the pneumatic pressing units also includes a pressure sensor, which is used to detect the actual downward pressure of the cylinder and feed the detection data back to the control system.

Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0022] like Figure 1 , Figure 2 As shown, this application provides a mobile power bank casing pressing device, comprising: Base 10; The pressing body 20 is disposed above the base 10. The pressing body 20 is provided with a plurality of pressing holes 21, which are used to place the mobile power supply shell assembly to be pressed. The pressing mechanism 30 is disposed above the pressing body 20 and corresponds to the plurality of pressing acupoints 21. The pressing mechanism 30 includes a plurality of independent pneumatic pressing units 31, each pneumatic pressing unit 31 corresponding to one pressing acupoint 21, and each pneumatic pressing unit 31 provides controllable downward pressure.

[0023] Multiple pressing slots 21 enable simultaneous pressing of multiple products without the need for repeated start-stop of the equipment, significantly reducing the waiting time for a single product and greatly improving overall production efficiency. At the same time, the independent pneumatic pressing unit 31 replaces manual pressure application, avoiding fluctuations in the force of manual operation and reducing problems such as poor sealing and shell deformation caused by uneven force from the source.

[0024] Secondly, this framework achieves adaptability to different types of power bank casings by individually adjusting pressure and time through a control system. In existing technologies, single-station pneumatic devices require adjustments to the entire device's parameters for different products, making product replacement cumbersome. However, the control system of this claim allows for individual parameter settings for each pneumatic unit. For example, pressure can be reduced and time shortened for ultra-thin power bank casings, while pressure can be increased and pressure holding time extended for multi-functional thick-cased power banks, eliminating the need for overall adjustments. This reduces changeover time and equipment downtime, avoiding the high cost of a dedicated device for each product. The control system receives signals and provides feedback for adjustments in real time, reserving interfaces for future additions such as pressure detection and abnormal alarms. Simultaneously, the layout of multiple acupoints and independent units facilitates the addition of safety protection structures (such as sensing areas around the acupoints), providing a fundamental support for the overall safety and stability of the device.

[0025] Furthermore, each of the aforementioned pressure points 21 is provided with a pressure head 22, which is made of silicone.

[0026] Each pressure plate 313 above the pressing point 21 is equipped with a pressing head 22 at its bottom. The pressing head 22 is made of food-grade silicone, which has good elasticity and wear resistance, and can prevent scratches on the outer shell surface during pressing. The silicone pressing head 22 has good elasticity and softness, and can fit tightly against the outer shell surface during pressing without generating rigid friction. Even if there is a slight displacement, the buffering effect of silicone can prevent scratches and significantly reduce the appearance defect rate.

[0027] Secondly, the elastic properties of the silicone pressure head 22 can help improve the consistency of pressing. During the injection molding process, there may be slight dimensional deviations in the power bank casing. Traditional rigid pressure heads 22 cannot accommodate these deviations, easily leading to excessive or insufficient local pressure (such as excessive pressure on protruding areas of the casing edge and insufficient pressure on recessed areas). The silicone pressure head 22, through its own elastic deformation, can conform to the slight undulations of the casing surface, allowing pressure to be evenly transmitted to the snap-fit ​​structure at the casing edge. This avoids localized gaps caused by casing dimensional deviations, further improving the sealing performance of the pressing.

[0028] Furthermore, the wear resistance and stability of silicone material extend the service life of the pressure head 22. Traditional hard pressure heads 22 are prone to surface wear after long-term use, leading to uneven pressure transmission and requiring frequent replacement. In contrast, silicone pressure heads 22 are not easily worn, and are resistant to high temperatures and aging. Even with prolonged contact with the outer plastic material, they will not stick or deteriorate due to chemical reactions, reducing the replacement frequency of the pressure head 22, lowering consumable costs and equipment downtime, and indirectly improving production efficiency.

[0029] Furthermore, the pressure head 22 has a partitioned design, which includes a central clearance area 221 and an edge pressing area 222. The clearance area 221 is used to avoid the battery, and the pressing area 222 is used to press the edge of the outer casing.

[0030] The pressure head 22 adopts a partitioned design: the center is a clearance area 221 (the diameter matches the size of the battery inside the power bank), which is used to avoid the battery area and prevent squeezing damage to the battery during pressing; the edge is a pressing area 222, which applies pressure only to the fastening structure of the shell edge to ensure a tight seal.

[0031] The 22-zone design of the pressure head effectively protects the internal battery of the power bank, avoiding the risk of battery damage during the pressing process. The battery is a core component of the power bank, and is mostly a lithium battery. If pressure is applied directly to the battery surface during pressing, it can easily cause deformation of the battery casing, damage to the internal cells, and even safety hazards. The central clearance zone 221 precisely avoids the battery area, ensuring that the pressure head 22 only contacts the edge of the casing, preventing pressure from being transmitted to the battery. Structurally, this eliminates the possibility of battery compression damage, making it particularly suitable for the production of ultra-thin power banks (with small gaps between the battery and the casing), thus improving product safety and reliability.

[0032] Secondly, this design enhances the sealing effect of the outer shell edges, solving the problem of poor sealing in traditional one-piece pressure heads 22. The sealing quality of the power bank shell directly affects the product's waterproofness and structural stability. Traditional pressure heads 22, needing to accommodate the battery area, cannot apply sufficient and uniform pressure to the edges, easily resulting in incomplete sealing and large gaps in the seams. The edge sealing area 222, however, concentrates the pressure from the pneumatic unit onto the snap-fit ​​structure at the edge of the shell, ensuring a tight fit and reducing gaps. Simultaneously, the silicone sealing area 222 can adapt to slight curvatures or protrusions on the edges, preventing localized pressure leakage and significantly improving the shell's sealing performance and structural strength.

[0033] Furthermore, each of the pressure heads 22 is detachably connected to the base 10.

[0034] In this embodiment, the pressure head 22 and the pressure plate 313 are connected by a snap-fit ​​and are detachable and replaceable. When different models of housings need to be adapted, only the pressure head 22 of the corresponding shape needs to be replaced, without adjusting the overall mechanism. The detachable pressure head 22 only requires replacing the corresponding partition pressure head 22 according to the size and shape of different models of housings (e.g., a circular pressure head 22 for a disc-shaped housing, and a rectangular pressure head 22 for a cuboid housing), without replacing core components such as the base 10 and the pressing mechanism 30. One device can meet the pressing needs of multiple models of products, significantly reducing equipment investment costs and space occupancy.

[0035] Secondly, this design significantly shortens product changeover time and improves equipment utilization. In existing technologies, replacing a dedicated pressing device requires disassembling and reassembling the entire machine, resulting in lengthy debugging times and potential production interruptions. However, the detachable pressing head 22, connected by snap-fit ​​or threads, allows operators to manually remove the old pressing head 22 and install the new one. The entire process requires no specialized tools and eliminates the need to readjust control system parameters (only preset parameters need to be called), greatly improving changeover efficiency. This is particularly important for small-batch, multi-batch power bank production, enabling rapid response to market order changes, reducing equipment downtime, and improving overall production efficiency.

[0036] Furthermore, the number of the compression acupoints 21 is four to eight.

[0037] In this embodiment, 4 to 8 acupoints can simultaneously press 4 to 8 products. Operators can place multiple products into the acupoints at the same time, and multiple products can be pressed in one start-up. There is no need to repeat the process of feeding, starting and unloading materials, which significantly reduces the number of times the equipment is started and stopped and the waiting time of operators. The overall production efficiency is greatly improved compared with traditional technology.

[0038] Secondly, this range of numbers balances production needs with equipment costs, making it widely applicable. If the number of acupoints is too small (e.g., 2), efficiency gains are limited and cannot meet the demands of mass production; if the number of acupoints is too large (e.g., more than 10), the base volume needs to be increased, and the number of pneumatic units increased, leading to higher equipment procurement costs and occupying more production space, making it unsuitable for small and medium-sized factories. A range of 4 to 8 acupoints can meet the mass production needs of most power bank manufacturers (e.g., daily production capacity of several thousand units) without excessively increasing equipment costs and space occupation. It also facilitates material loading and unloading by operators (the moderate number of acupoints reduces the likelihood of missed or incorrect placement), balancing efficiency and practicality.

[0039] Furthermore, each of the pneumatic pressing units 31 includes a cylinder 311, a connecting rod 312, and a pressure plate 313. The cylinder 311 drives the connecting rod 312 to reciprocate, and the connecting rod 312 drives the pressure plate 313 to press the mobile power supply housing assembly located in the pressing cavity 21.

[0040] The cylinder 311 is fixed to the mounting hole of the mounting plate 12, and its output end is connected to one end of the connecting rod 312. The other end of the connecting rod 312 is fixed to the pressure plate 313 (using a threaded connection, which is detachable). The cylinder 311 can drive the connecting rod 312 to drive the pressure plate 313 to reciprocate in the vertical direction, realizing the pressing and resetting action. In this application, through the rigid transmission path of the cylinder 311, the connecting rod 312, and the pressure plate 313, the pressure output by the cylinder 311 can be directly and losslessly transmitted to the pressure plate 313, and then transmitted to the edge of the outer shell through the pressure plate 313. The pressure transmission process is stable and traceable, and will not fluctuate due to the operation method or personnel status, thus ensuring the consistency of the pressing pressure from the structure.

[0041] Furthermore, the base 10 includes a base 11 and a mounting plate 12. The mounting plate 12 is connected above the base 11. The pressing body 20 is disposed on the base 11. The mounting plate 12 extends horizontally. A plurality of pneumatic pressing units 31 are spaced apart on the mounting plate 12.

[0042] The base 10 is divided into a base 11 and a mounting plate 12. The base 11 is made of high-strength material, providing stable bottom support and preventing the device from shaking. The mounting plate 12 is horizontally connected above the base 11, and its surface is precision machined (with small flatness error). Pneumatic units are installed on the mounting plate 12 at intervals, which can ensure that the axis of each pneumatic unit is precisely aligned with the center of the pressing cavity 21. Structurally, this eliminates pressing deviation caused by the instability of the base 10 and ensures pressing accuracy.

[0043] Secondly, this structural design makes the installation and adjustment of the pneumatic unit more convenient. The mounting plate 12 extends horizontally and has multiple mounting holes (which can be adjusted according to the number of acupoints). If it is necessary to add or remove pneumatic units (such as from 4 to 6), only the units need to be added or removed on the mounting plate 12, without modifying the base 11. At the same time, the horizontal design of the mounting plate 12 makes it easy for operators to observe and adjust the position of the pneumatic unit. If there is a slight misalignment, precise alignment can be achieved by fine-tuning the mounting bolts, without the need for professional equipment.

[0044] Furthermore, the pneumatic pressing unit 31 also includes a guide rod 314, one end of which is fixedly connected to the base 11 and the other end is movably connected to the pressure plate 313.

[0045] Specifically, two guide rods 314 are provided, symmetrically distributed on both sides of the cylinder 311. One end is fixed to the base 11, and the other end movably passes through the pressure plate 313 (the pressure plate 313 has a guide hole that is clearance-fitted with the guide rod 314). These guide rods are used to limit the movement direction of the pressure plate 313, prevent the pressure plate 313 from shifting when pressing down, and ensure pressing accuracy. The guide rod 314, with one end fixed to the base 11 and the other end movably passing through the pressure plate 313, forms a double guide structure. This structure can forcibly restrict the pressure plate 313 to move only in the vertical direction. Regardless of whether there is slight shaking of the output shaft of the cylinder 311, the pressure plate 313 will not shift horizontally and will always be precisely aligned with the center of the pressing position 21. This ensures that the pressure is evenly applied to every fastening structure on the edge of the outer shell, thus ensuring the consistency of pressing from the movement trajectory.

[0046] Furthermore, each of the pneumatic pressing units 31 also includes a pressure sensor, which is used to detect the actual downward pressure of the cylinder 311 and feed the detection data back to the control system.

[0047] A pressure sensor is installed at the connection between the connecting rod 312 and the pressure plate 313. It can detect the actual downward pressure applied by the pressure plate 313 in real time and convert the detection data into an electrical signal to feed back to the control system. The control system is electrically connected to the pressing mechanism 30 and the pressure sensor. The control system adopts a PLC controller and is equipped with a touch screen display. The control system can set the downward pressure of each pneumatic pressing unit 31 independently without interference; for example, a lower pressure can be set for ultra-thin shells, and a higher pressure can be set for thicker shells. Upon receiving the detection data from the pressure sensor, if the actual pressure exceeds the set range, an alarm signal is immediately issued and the operation of the corresponding pneumatic unit is stopped to avoid product damage. Furthermore, it can store 10-20 sets of pressing parameters for different products. When switching products, the preset parameters can be directly recalled without re-adjustment, shortening the changeover time.

[0048] Furthermore, the power bank housing pressing device also includes a safety protection device, which includes a two-hand start button 51 and an emergency stop switch 52.

[0049] The two-hand start button 51 is located on both sides of the base 10. The operator must press both buttons at the same time for the pressing mechanism 30 to start. If only one button is pressed or the hand is inserted into the pressing area 222, the device will not start, preventing hand injury due to misoperation. The emergency stop switch 52 is located in a conspicuous position on the front of the base 10. In case of emergency (such as product jamming or equipment malfunction), pressing the emergency stop switch 52 can immediately cut off the power and stop all mechanism operations.

[0050] It is understood that the above embodiments only illustrate preferred embodiments of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present utility model patent. It should be noted that for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present utility model, all of which fall within the protection scope of the present utility model. Therefore, all equivalent transformations and modifications made within the scope of the claims of the present utility model should fall within the coverage of the claims of the present utility model.
