Description

Technical Field

[0001] This utility model relates to the field of fuel cell assembly technology, and in particular to an electrolytic stack assembly device. Background Technology

[0002] As the core energy conversion unit, the fuel cell electrolyzer stack typically consists of a bottom end plate, multiple stacked individual cells, and a top end plate, which are locked and sealed by a through screw and nut.

[0003] Currently, the automation level of mainstream fuel cell stack assembly equipment is generally low. The assembly process relies heavily on manual operation, mainly using a single press for stacking and pre-compression. Moving the stack components during assembly also depends heavily on manual handling. This model is not only cumbersome and involves many steps, but also struggles to adapt to the rapid switching requirements of different fuel cell stack specifications. The lack of automated equipment makes the entire assembly process inefficient, becoming a key bottleneck restricting capacity expansion.

[0004] Furthermore, the intervention of manual operations makes it difficult to guarantee the consistency and stability of assembly precision, directly affecting the performance and sealing reliability of the fuel cell stack, leading to fluctuations in product quality. Low production efficiency and a large investment of manpower also significantly increase manufacturing costs. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of low efficiency caused by insufficient automation in the assembly of electrolytic reactors in the prior art, and to provide an electrolytic reactor assembly device.

[0006] The present invention solves the above-mentioned technical problems through the following technical solution:

[0007] This utility model provides an electrolytic reactor assembly device, which includes: a material gripping mechanism, a sliding platform, a clamping mechanism, and a control device; the control device is electrically connected to the material gripping mechanism and is used to control the material gripping mechanism to sequentially grip and stack the bottom end plate, single cell, and top end plate onto the sliding platform; the control device is electrically connected to the sliding platform and is used to control the movement of the sliding platform so that the sliding platform moves below the clamping mechanism; the control device is electrically connected to the clamping mechanism and is used to control the clamping mechanism to apply pressure to the electrolytic reactor on the sliding platform.

[0008] In this solution, the electrolytic reactor assembly equipment, through the cooperation of the material grabbing mechanism, the sliding platform and the clamping mechanism, achieves automatic grabbing of electrolytic reactor parts under the control of the control equipment, and transports the assembled electrolytic reactor parts to the bottom of the clamping mechanism through the sliding platform. This avoids manual handling, achieving the effect of saving time and labor, realizing automated production of electrolytic reactors, and significantly improving production efficiency.

[0009] Preferably, the sliding platform includes a drive mechanism, a platform body, a slide rail, and a blocking component. The control device is electrically connected to the drive mechanism. The platform body is slidably disposed on the slide rail. The drive mechanism is connected to the platform body and is used to drive the sliding of the platform body. The blocking component is located at the end of the slide rail and is used to stop the platform body directly below the pressing mechanism.

[0010] In this solution, the above-mentioned settings allow for precise control of the platform's stopping position under the action of the blocking components, ensuring that the platform is positioned directly below the pressing mechanism and reducing the possibility of uneven pressure caused by positional deviation.

[0011] Preferably, the electrolytic reactor assembly equipment further includes a travel detection mechanism, which is disposed on the travel path of the platform body and is electrically connected to the control device for controlling the moving speed and / or stopping of the platform body.

[0012] In this solution, through the above settings, the travel detection mechanism can detect the position of the platform body. When the platform body passes through the preset position, the control device can decelerate or stop the platform body to prevent the platform body from being damaged by excessive speed when it comes into contact with the blocking component.

[0013] Preferably, the blocking component includes a stop plate disposed at the end of the slide and an abutment portion disposed on the stop plate. One end of the abutment portion is connected to the stop plate, and the other end of the abutment portion extends toward the platform body. A rubber head is provided at the end of the abutment portion toward the platform body.

[0014] In this solution, the rubber head of the blocking component can provide cushioning at the first moment of contact with the platform body, thereby reducing the impact force on the platform body and preventing damage to the equipment.

[0015] Preferably, the blocking component further includes a spring, which is sleeved on the abutment portion, and the abutment portion is capable of telescoping along the axial direction of the spring.

[0016] In this solution, the spring and the retractable abutment part, through the above-mentioned configuration, can provide further cushioning for the platform body and prevent damage to the equipment.

[0017] Preferably, the clamping mechanism includes a pressure head with a pressure plate, the pressure head being able to push the pressure plate downward, the pressure plate including a connecting plate, a connecting column and a contact plate, the connecting plate being used to connect with the pressure head, the connecting column being connected between the connecting plate and the contact plate, and the contact plate being used to apply pressure to the electrolytic reactor on the sliding platform.

[0018] In this scheme, the above-mentioned settings enable the clamping mechanism to clamp the assembled electrolytic reactor on the sliding platform more evenly through the pressure head and pressure plate, which facilitates the subsequent installation of fixing bolts under appropriate pressure.

[0019] Preferably, there are multiple pressure plates, the connecting column lengths of the multiple pressure plates are different, and the multiple pressure plates are replaceable.

[0020] In this solution, the above settings can provide a variety of pressure plate options for the pressure head, thereby adapting to electrolytic reactors of different heights (i.e., different numbers of single cells installed). If a single-height pressure plate is used, the requirements for the press are very high, requiring a large cylinder stroke, which increases the machine cost.

[0021] Preferably, the electrolytic reactor assembly equipment further includes an airtightness detection mechanism, which includes a leak detection cabinet, a detection head extending into the electrolytic reactor, and a pipeline connecting the detection head and the leak detection cabinet. The detection head extends into the electrolytic reactor to detect the internal airtightness of the electrolytic reactor, and the leak detection cabinet is electrically connected to the control device to transmit the detection results to the control device.

[0022] In this solution, the above-mentioned setup allows for leak detection of the electrolytic reactor using an airtightness testing mechanism. If the airtightness fails to meet the requirements, adjustments can be made immediately based on the leak point, followed by reassembly and airtightness testing. This avoids multiple disassembly and handling of the electrolytic reactor, saving production time and significantly improving assembly efficiency.

[0023] Preferably, the electrolytic reactor assembly equipment further includes multiple material placement platforms, which are used to place the bottom end plate, the single cell, and the top end plate, respectively.

[0024] In this solution, the bottom end plate, single battery, and top end plate are placed on different material placement platforms, which facilitates the material gripping mechanism to position each material placement platform to grip the required materials, thereby improving the efficiency of gripping and thus improving the efficiency of assembly.

[0025] Preferably, the material gripping mechanism is a robotic arm.

[0026] The positive and progressive effects of this utility model are as follows:

[0027] This utility model provides an electrolytic reactor assembly device. Through the cooperation of the material gripping mechanism, the sliding platform and the clamping mechanism, the electrolytic reactor parts are automatically gripped under the control of the control equipment. The assembled electrolytic reactor parts are transported to the bottom of the clamping mechanism through the sliding platform, avoiding manual handling and achieving the effect of saving time and labor. This realizes the automated production of electrolytic reactors and significantly improves production efficiency. Attached Figure Description

[0055] Electrolytic reactor 2000 Detailed Implementation

[0056] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.

[0057] like Figures 1 to 7 As shown, this embodiment provides an electrolytic reactor assembly device 1000, such as... Figure 1 As shown, the electrolytic reactor assembly equipment 1000 includes: a material gripping mechanism 1, a sliding platform 2, a clamping mechanism 3, and a control device. The control device is electrically connected to the material gripping mechanism 1 and controls it to sequentially grip and stack the bottom end plate, single cell, and top end plate onto the sliding platform 2. The material gripping mechanism 1 is a robotic arm. The control device is electrically connected to the sliding platform 2 and controls its movement, moving it below the clamping mechanism 3. The control device is also electrically connected to the clamping mechanism 3 and controls it to apply pressure to the electrolytic reactor 2000 on the sliding platform 2.

[0058] Thus, the electrolytic reactor assembly equipment 1000, through the cooperation between the material grabbing mechanism 1, the sliding platform 2, and the clamping mechanism 3, achieves automatic grabbing of electrolytic reactor 2000 parts under the control of the control equipment, and transports the assembled electrolytic reactor 2000 to the underside of the clamping mechanism 3 via the sliding platform 2. This avoids manual handling, achieving time and labor savings, realizing automated production of electrolytic reactor 2000, and significantly improving production efficiency.

[0059] Specifically, such as Figure 2As shown, the sliding platform 2 includes a drive mechanism, a platform body 201, a slide rail 202, and a blocking component 203. A control device is electrically connected to the drive mechanism; in this embodiment, the drive mechanism is a motor. The platform body 201 is slidably mounted on the slide rail 202. The motor is electrically connected to the platform body 201 and drives it to slide along the slide rail 202. The blocking component 203 is located at the end of the slide rail 202 and stops the platform body 201 directly below the clamping mechanism 3. "The blocking component 203 is located at the end of the slide rail 202" means that it is positioned at the end of the platform body 201's movement along the slide rail 202. Generally, the clamping mechanism 3 is assembled after the electrolytic reactor 2000 is clamped and the fixing screws are installed. Only the platform body 201 needs to be retracted and then hoisted out; that is, the slide rail 202 does not need to be installed after the clamping mechanism 3. The blocking component 203 at the end can stop the platform body 201. With the above settings, the stopping position of the platform body 201 can be precisely controlled under the action of the blocking component 203, so that the platform body 201 can stop directly below the pressing mechanism 3, reducing the possibility of uneven pressure caused by position deviation.

[0060] Furthermore, such as Figure 2 As shown, the electrolytic reactor assembly equipment 1000 also includes a travel detection mechanism 4. The travel detection mechanism 4 is disposed on the travel path of the platform body 201 and is electrically connected to the control device to control the moving speed of the platform body 201. The travel detection mechanism 4 is disposed on the slide rail 202 on the side near the blocking component 203. When the platform body 201 passes through the travel detection mechanism 4, the position of the platform body 201 can be converted into an electrical signal and transmitted to the control device. The control device controls the platform body 201 to decelerate or decelerate to zero to stop.

[0061] Thus, through the above settings, the travel detection mechanism 4 can detect the position of the platform body 201. When the platform body 201 passes through the preset position, the control device can decelerate or stop the platform body 201 to prevent the platform body 201 from being damaged by excessive speed when it comes into contact with the blocking component 203.

[0062] In this embodiment, the travel detection mechanism 4 is a photosensitive sensor. The photosensitive sensor is set on the slide 202 of the travel path of the platform body 201, and the vertical projection of the photosensitive sensor falls on the travel path of the platform body 201. That is, when the platform body 201 passes the photosensitive sensor, it can cover the photosensitive sensor, thereby changing the intensity of the light received by the photosensitive sensor, and thus realizing the conversion of the sensing position of the platform body 201 into an electrical signal and transmitting it to the control device.

[0063] Specifically, such as Figure 7As shown, the blocking component 203 includes a stop plate 2032 disposed at the end of the slide 202 and an abutment portion 2031 disposed on the stop plate 2032. One end of the abutment portion 2031 is connected to the stop plate 2032, and the other end of the abutment portion 2031 extends toward the platform body 201. A rubber head 2033 is disposed at the end of the abutment portion 2031 facing the platform body 201. Thus, through the above arrangement, the rubber head 2033 of the blocking component 203 can provide cushioning at the first moment when the abutment portion 2031 contacts the platform body 201, reducing the impact force on the platform body 201 and preventing damage to the equipment.

[0064] Furthermore, the blocking component 203 also includes a spring, which is sleeved on the abutment portion 2031, and the abutment portion 2031 can extend and retract along the axial direction of the spring. In this way, through the above arrangement, the spring and the extendable abutment portion 2031 can provide further cushioning for the platform body 201 and prevent damage to the equipment.

[0065] Specifically, such as Figure 5 and Figure 6 As shown, the clamping mechanism 3 includes a pressure head 301 with a pressure plate 302. The pressure head 301 is connected to a press, and the press provides power for the movement of the pressure head 301. The pressure head 301 can push the pressure plate 302 downward. Figure 4 As shown, the pressure plate 302 includes a connecting plate 3021, a connecting column 3022, and a contact plate 3023. The connecting plate 3021 is used to connect to the pressure head 301, the connecting column 3022 is connected between the connecting plate 3021 and the contact plate 3023, and the contact plate 3023 is used to apply pressure to the electrolytic reactor 2000 on the sliding platform 2.

[0066] Thus, through the above-mentioned arrangement, the clamping mechanism 3 can use the pressure head 301 and the pressure plate 302 to clamp the assembled electrolytic reactor 2000 on the sliding platform 2 more evenly, which facilitates the subsequent installation of fixing bolts under appropriate pressure.

[0067] Furthermore, there are multiple pressure plates 302, the connecting posts 3022 of the multiple pressure plates 302 have different lengths, and the multiple pressure plates 302 are replaceable. For example... Figure 5 and Figure 6 The figures shown are assembly diagrams of two pressure plates 302 of different lengths. There are two pressure plates 302, but this number is only illustrative and not limited in this embodiment. Thus, through the above arrangement, multiple pressure plates 302 can be selected for the pressure head 301, thereby adapting to electrolytic reactors 2000 of different heights (i.e., different numbers of single cells installed). If a single-height pressure plate 302 is used, the requirements for the press are very high, requiring a large cylinder stroke, leading to increased machine costs.

[0068] Specifically, such as Figure 1As shown, the electrolytic reactor assembly equipment 1000 also includes an airtightness detection mechanism 5. The airtightness detection mechanism 5 includes a leak detection cabinet, a detection head extending into the electrolytic reactor 2000, and a pipeline connecting the detection head and the leak detection cabinet. The detection head extends into the electrolytic reactor 2000 to detect the internal airtightness of the electrolytic reactor 2000. The leak detection cabinet is electrically connected to a control device to transmit the detection results to the control device. The leak detection cabinet includes internal high-pressure pipelines, connectors, and pressure gauges. An external screen is installed on the leak detection cabinet to control the leak detection action and parameter settings of the electrolytic reactor 2000. A storage disk is also provided to save backups of parameters of different specifications for direct retrieval during repeated use.

[0069] Thus, through the above setup, the airtightness testing mechanism 5 is used to detect leaks in the electrolytic reactor 2000. If the airtightness is not up to standard, adjustments can be made immediately based on the leak point, and the reactor can be reassembled and the airtightness tested again. This avoids multiple disassemblies and handling of the electrolytic reactor 2000, saving production time and greatly improving assembly efficiency.

[0070] In this embodiment, the control device has built-in control software that can issue an alarm when the airtightness fails to meet the requirements.

[0071] Specifically, such as Figure 1 As shown, the electrolytic reactor assembly equipment 1000 also includes multiple material placement platforms 6, which are used to place the bottom end plate, single cell, and top end plate respectively. Figure 1 and Figure 3 As shown, there are three material placement platforms 6, which, from left to right, hold a single battery, a bottom end plate, and a top end plate. The placement surface of the material placement platform 6 has positioning components, including but not limited to positioning posts, positioning blocks, and positioning holes.

[0072] Thus, through the above arrangement, the bottom end plate, single battery and top end plate are placed on different material placement platforms 6 respectively, which makes it easier for the material gripping mechanism 1 to position each material placement platform 6 to grip the required materials, thereby improving the efficiency of gripping and thus improving the efficiency of assembly.

[0073] Specifically, such as Figure 1 As shown, the electrolytic reactor assembly equipment 1000 also includes a gantry crane 7, which is used to move the entire reactor stack and features multi-stage speed regulation. The gantry crane 7 has four support columns, which are fixed to the ground using expansion bolts, ensuring safety and reliability. A transport vehicle can be provided at the assembly site.

[0074] The operation process of this electrolytic reactor assembly equipment 1000 is as follows: First, all materials are manually placed on the material placement platform 6. The robotic arm picks up and places the pre-assembled electrolytic reactor 2000 in the order of bottom end plate, multiple single cells, and top end plate, forming the pre-assembled electrolytic reactor 2000. Then, the fixing bolts are pre-tightened manually. After pre-tightening, the electrolytic reactor 2000 slides along the slide 202 to below the pressing mechanism 3. During this process, it decelerates and stops after contacting the blocking component 203 when passing through the forming detection mechanism. The pressure plate 302 applies pressure to the electrolytic reactor 2000 for pre-pressurization. After pre-pressurization reaches the predetermined pressure, the pressure is maintained. Then, the fixing bolts are tightened manually. The pressure holding time can be adjusted as needed. During the pressure holding period, a protective device is required to protect personnel safety. After the pressure holding is completed, the airtightness is tested using the airtightness testing mechanism 5. After the test is passed, the platform body 201 slides out from under the pressing mechanism 3, and the assembled electrolytic reactor 2000 is lifted out by the gantry crane 7.

[0075] While specific embodiments of this utility model have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
