The mounting plate is driven by the first linear drive device and can move along the second direction. The mounting plate is provided with a lifting drive device. The vacuum adsorption part is disposed at the power output end of the lifting drive device.

[0011] Furthermore, the mounting plate is equipped with the vacuum adsorption unit and the lifting drive device corresponding to the workstation platform and the preset position.

[0012] Furthermore, the workstation platform is equipped with an air blowing mechanism; the air blowing mechanism is used to blow away any excess explosion-proof valves on the vacuum adsorption section.

[0013] Furthermore, the storage bin assembly also includes a material detection component disposed on the workstation platform; the material detection component is used to detect whether there is material in the storage bin when it moves to the loading position, and / or, the material detection component is used to detect whether there is material in the preset position.

[0014] Furthermore, the workstation platform is provided with a placement slot for placing the explosion-proof valve, and the workstation platform is provided with a positioning mechanism for positioning the explosion-proof valve in the placement slot.

[0015] Furthermore, the placement slot has a first limiting stop and a second limiting stop; the positioning mechanism includes a first positioning block that can move closer to or further away from the first limiting stop, and a second positioning block that can move closer to or further away from the second stop; the first positioning block and the first limiting stop can abut against the side of the explosion-proof valve in the width direction to position the explosion-proof valve in the length direction, and the second positioning block and the second limiting stop can abut against the side of the explosion-proof valve in the length direction to position the explosion-proof valve in the width direction.

[0017] Furthermore, the suction and transplanting components are two sets arranged opposite to each other; the storage bin assembly includes a support plate that moves along the first direction, and multiple storage bins are arranged at intervals on the support plate, and the multiple storage bins move alternately to the feeding position in pairs.

[0018] Compared with the prior art, this utility model has the following advantages:

[0019] The explosion-proof valve feeding device of this utility model comprises a lifting assembly, a storage bin assembly, and a suction and transfer assembly. The storage bin assembly includes multiple storage bins that move alternately along the first direction of the workstation platform. The lifting component in the lifting assembly extends from the bottom of the storage bin at the feeding position into the storage bin, lifting multiple explosion-proof valves to a preset position. Then, the suction and transfer assembly sequentially picks up individual explosion-proof valves and transfers them to the workstation platform. This not only simplifies the structure of the explosion-proof valve feeding device, reducing manufacturing costs, but also allows for replenishment of storage bins other than the feeding position during the feeding process, enabling online feeding of explosion-proof valves without stopping the machine. This improves the feeding efficiency of explosion-proof valves and has excellent performance.

[0020] In addition, the suction and transfer assembly includes a connected vacuum suction unit and a drive assembly. The vacuum suction unit can reliably suction the explosion-proof valve, while the drive assembly can control the lifting and horizontal movement of the vacuum suction unit, making the suction and transfer of the explosion-proof valve more precise and reliable, thereby improving the accuracy and stability of the feeding process.

[0021] Secondly, the drive assembly includes a first linear drive device, a mounting plate located at the power output end of the first linear drive device, and a lifting drive device located on the mounting plate. This allows the vacuum adsorption unit to be positioned at the power output end of the lifting drive device. Under the drive of the lifting drive device, the vacuum adsorption unit can adsorb the explosion-proof valve at a preset position. Furthermore, driven by the first linear drive device, the mounting plate and the lifting drive device can move along a second direction, thereby transferring the explosion-proof valve sucked by the vacuum adsorption unit from the preset position to the workstation platform. Its structure is relatively simple and compact, which helps reduce the manufacturing cost of the explosion-proof valve feeding device and facilitates equipment maintenance and repair.

[0022] Furthermore, the mounting plate is equipped with vacuum adsorption units and lifting devices at both the corresponding workstation platform and the preset position. This allows the vacuum adsorption units at the two positions to move synchronously, adsorbing the explosion-proof valves on the workstation platform and the explosion-proof valves at the preset position simultaneously, and transferring them synchronously. This allows the explosion-proof valves at the preset position to be transferred to the workstation platform, and the explosion-proof valves on the workstation platform to be transferred to the next process, thereby further improving the feeding efficiency of the explosion-proof valves.

[0023] The air-blowing mechanism installed on the workstation platform can blow away excess explosion-proof valves on the vacuum adsorption section, ensuring that only one explosion-proof valve is used for each feeding, thus improving feeding accuracy. The material detection component can detect the presence or absence of material in the storage bin at the feeding position, promptly identifying whether the bin is empty for timely replenishment. Detecting the presence or absence of material at preset positions ensures that the preset position is accessible by the explosion-proof valve when the suction and transfer component is operating, avoiding errors such as empty suction, thereby improving the reliability and stability of equipment operation.

[0024] In addition, the placement slots for explosion-proof valves on the workstation platform provide an accurate placement position for the explosion-proof valves that are transferred to the workstation platform by the suction and transfer components. The positioning mechanism can position the explosion-proof valves in the placement slots to ensure the positional accuracy of the explosion-proof valves, thereby helping to ensure the manufacturing accuracy of subsequent processes.

[0025] The placement slot is equipped with a first limiting stop and a second limiting stop. The positioning mechanism includes a first positioning block and a second positioning block. When the explosion-proof valve is placed in the placement slot, the movement of the first positioning block and the second positioning block causes the first positioning block and the first limiting stop to abut against the side of the explosion-proof valve in the width direction, and the second positioning block and the second limiting stop to abut against the side of the explosion-proof valve in the length direction. This allows for better positioning of the explosion-proof valve in both the length and width directions.

[0026] In addition, the lifting assembly includes a through-shaft stepper motor and a guide structure, enabling bottom-up clip-on feeding of the explosion-proof valves and ensuring feeding accuracy. The suction and transfer assembly is arranged in two opposing groups, with multiple storage bins moving alternately to the feeding position in pairs, further improving the feeding efficiency of the explosion-proof valves.

Those skilled in the art can understand the specific meaning of the above terms in this utility model in light of the specific circumstances.

[0045] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0046] This embodiment relates to an explosion-proof valve feeding device, which can improve the feeding efficiency of explosion-proof valves.

[0047] In terms of overall structure, such as Figure 1 and Figure 2 As shown, the explosion-proof valve feeding device of this embodiment includes a work platform 1, a lifting component 3, a storage bin component 2 and a suction and transfer component 4 disposed on the work platform 1.

[0048] The storage silo assembly 2 includes multiple storage silos 23, which can alternately move along the first direction of the workstation platform 1 to the loading position. Each storage silo 23 is used to hold multiple explosion-proof valves arranged in layers. The lifting assembly 3 is located below the storage silo assembly 2 and includes a lifting member that can be raised and lowered. The lifting member can pass through the through hole 230 at the bottom of the storage silo 23 located at the loading position and extend into the storage silo 23 to lift the multiple explosion-proof valves to a preset position. The suction and transfer assembly 4 is used to sequentially suction a single explosion-proof valve at the preset position and sequentially transfer the suctioned single explosion-proof valve to the workstation platform 1.

[0049] In the above structure, by setting multiple storage bins 23 that move alternately along the first direction of the workstation platform 1, the lifting component in the lifting assembly 3 extends from the bottom of the storage bin 23 at the loading position into the storage bin 23, lifting multiple explosion-proof valves to a preset position. Then, the suction and transfer assembly 4 sequentially picks up individual explosion-proof valves and transfers them to the workstation platform 1. This not only simplifies the structure of the explosion-proof valve loading device and helps reduce the manufacturing cost of the equipment, but also allows for replenishment of storage bins 23 other than the loading position during the explosion-proof valve loading process, enabling online loading of explosion-proof valves without stopping the machine, thereby improving the loading efficiency of explosion-proof valves.

[0050] Based on the overall structure above, for more details please refer to [link / reference]. Figure 1 and Figure 2 and combined Figure 3 and Figure 4 As shown in the preferred embodiment, in this example, the storage bin assembly 2 includes a transverse drive device 21 mounted on the workstation platform 1, and a support plate 22 mounted on the power output end of the transverse drive device 21. The support plate 22 has multiple storage bins 23 arranged at intervals. Driven by the transverse drive device 21, the support plate 22 can move along the first direction of the workstation platform 1, and drive the multiple storage bins 23 to alternately move to the loading position for loading the explosion-proof valve.

[0051] In this embodiment, the explosion-proof valve is a sheet-like structure installed on the battery cover, and each storage bin 23 can only accommodate one row of explosion-proof valves stacked together. Figure 4 As shown, each storage bin 23 has a through hole 230 at the bottom for the lifting component to pass through, so that the lifting component can lift multiple explosion-proof valves to a preset position.

[0052] Continue reading Figures 1 to 4 In this embodiment, preferably, the storage bin assembly 2 further includes a material detection assembly 24 disposed on the workstation platform 1. This material detection assembly 24 is used to detect the presence or absence of material in the storage bin 23 when it is moved to the loading position. Furthermore, the material detection assembly 24 is also used to detect the presence or absence of material at a preset position. By detecting the presence or absence of material in the storage bin 23 at the loading position, it is possible to promptly determine whether the material in the storage bin 23 is depleted, facilitating timely replenishment. Detecting the presence or absence of material at the preset position ensures that the preset position is accessible for suction by an explosion-proof valve when the suction and transfer assembly 4 is operating, avoiding errors such as dry suction, thereby improving the reliability and stability of the equipment operation.

[0053] Specifically, the material detection component 24 includes a first detection component 241 and a second detection component 242, with the first detection component 241 located below the second detection component 242. The first detection component 241 detects the presence or absence of material in the storage hopper 23 as it moves to the loading position, while the second detection component 242 detects the presence or absence of material at a preset position. In specific implementations, the first detection component 241 and the second detection component 242 can, for example, employ reflective photoelectric sensors as used in the prior art.

[0054] It should be noted that, in addition to all having a first detection component 241 and a second detection component 242, the aforementioned material detection component 24 may also have only the first detection component 241 or only the second detection component 242, which is also feasible. Furthermore, the aforementioned lateral drive device 21 preferably adopts a linear module, which is technically mature, widely used, and can ensure the movement accuracy of the storage bin 23. Of course, it is understood that the lateral drive device 21 may also adopt an electric cylinder, hydraulic cylinder, or pneumatic cylinder, etc.

[0055] As a preferred embodiment, such as Figure 2 and Figure 3 As shown, in this embodiment, the lifting assembly 3 includes a through-shaft stepper motor 31 fixed on the workstation platform 1 and a guide structure. The guide structure includes a guide rail 32 extending along the height direction of the workstation platform 1 and a sliding block 33 sliding on the guide rail 32. One end of the lead screw 311 of the through-shaft stepper motor 31 is connected to the sliding block 33, and the other end is connected to the lifting component. When the through-shaft stepper motor 31 is activated, the lead screw 311 drives the lifting component to move up and down along the height direction of the tooling platform. Under the pushing force of the lifting component, multiple explosion-proof valves are lifted to preset positions.

[0056] In this embodiment, by employing a through-shaft stepper motor 31 and a guiding structure, the explosion-proof valve can be fed from bottom to top using a clip-on method, ensuring the accuracy of the explosion-proof valve feeding. Furthermore, the lifting component can be formed by the upper end of the lead screw shaft 311, or it can be formed by a separate rod-shaped component, in which case the rod-shaped component is fixedly connected to the upper end of the lead screw shaft 311.

[0057] In a preferred embodiment, the suction and transfer assembly 4 includes a connected vacuum suction unit 43 and a drive assembly. The vacuum suction unit 43 is used to suction a single explosion-proof valve at a preset position. The drive assembly can move the vacuum suction unit 43 up and down to approach the preset position, and can also move the vacuum suction unit 43 along a second direction of the workstation platform 1 to transfer the suctioned single explosion-proof valve between the preset position and the workstation platform 1. The arrangement of the vacuum suction unit 43 and the drive assembly makes the suction and transfer of the explosion-proof valve more precise and reliable, facilitating the fulfillment of different positional requirements and improving the accuracy and stability of explosion-proof valve loading.

[0058] In terms of specific structure, combined Figure 5 and Figure 7 As shown, the drive assembly includes a first linear drive device 41 mounted on a tooling platform and a mounting plate 401 located at the power output end of the first linear drive device 41. The mounting plate 401 is driven by the first linear drive device 41 and can move in a second direction. A lifting drive device 42 is mounted on the mounting plate 401, and the aforementioned vacuum suction unit 43 is located at the power output end of the lifting drive device 42. In a specific implementation, the vacuum suction unit 43 includes several suction nozzles located at the power output end of the lifting drive device 42.

[0059] As a further preferred embodiment, in this embodiment, please continue to refer to... Figure 5 and Figure 7 As shown, a first movable plate 402 is provided on the mounting plate 401, and a second movable plate 403 is provided on the first movable plate 402. A first sliding structure is provided between the mounting plate 401 and the first movable plate 402, and a second sliding structure is provided between the first movable plate 402 and the second movable plate 403. An elastic element 400 is provided between the first movable plate 402 and the second movable plate 403. Simultaneously, the power output end of the lifting drive device 42 is connected to the first movable plate 402.

[0060] The first sliding structure includes a first slide rail 4011 disposed on the mounting plate 401 and a first slider disposed on the first moving plate 402. The length direction of the first slide rail 4011 extends along the height direction of the tooling platform, and the first slider is embedded and slides on the first slide rail 4011. The second sliding structure includes a second slide rail 4021 disposed on the first moving plate 402 and a second slider disposed on the second moving plate 403. The length direction of the second slide rail 4021 also extends along the height direction of the tooling platform, and the second slider is embedded and slides on the second slide rail 4021.

[0061] Thus, through the first sliding structure, the first moving plate 402 can smoothly move up and down along the height direction of the tooling platform under the drive of the lifting drive device 42. When the lifting drive device 42 suddenly stops, the elastic element 400 and the second sliding structure can buffer the movement of the second moving plate 403, that is, they can buffer the vacuum adsorption part 43, preventing the vacuum adsorption part 43 from damaging the explosion-proof valve at the preset position, and facilitating the reliable adsorption of the explosion-proof valve.

[0062] See also Figure 5 and Figure 7 As shown, in this embodiment, preferably, a vacuum adsorption unit 43 and a lifting drive device 42 are provided on the mounting plate 401 corresponding to the workstation platform 1 and the preset position. This allows the vacuum adsorption units at the two positions to move synchronously, meaning that the two vacuum adsorption units 43 can simultaneously adsorb the explosion-proof valve on the workstation platform 1 and the explosion-proof valve at the preset position. The movement of the mounting plate 401 enables the synchronous transfer of the two explosion-proof valves, allowing the explosion-proof valve at the preset position to be transferred to the workstation platform 1, and the explosion-proof valve on the workstation platform 1 to be transferred to the next process, thereby further improving the loading efficiency of the explosion-proof valves.

[0063] When the vacuum adsorption section 43 adsorbs a single explosion-proof valve, the explosion-proof valve located on the lower layer may stick to the explosion-proof valve to be adsorbed. In order to ensure that the vacuum adsorption section 43 only picks up a single explosion-proof valve each time, in this embodiment, preferably, an air blowing mechanism is provided on the workstation platform 1. The air blowing mechanism is used to blow away the excess explosion-proof valves on the vacuum adsorption section 43.

[0064] In practice, the air blowing mechanism may include, for example, an air source and an air nozzle, as well as an air pipe connecting the air source and the air nozzle. When the explosion-proof valve is sucked in, any excess explosion-proof valve adhering to its lower part can be blown away by the air nozzle, thereby ensuring that only one explosion-proof valve is used for each feeding, thus improving the accuracy of feeding.

[0065] It is worth noting that, in this embodiment, the first linear drive device 41, like the lateral drive device 21 described above, is preferably a linear module, and the lifting drive device 42 is preferably a cylinder. The elastic element 400 is preferably a spring.

[0066] Depend on Figure 5 Combination Figure 6 As shown, in this embodiment, the workstation platform 1 is provided with a placement slot 100 for placing the explosion-proof valve. The explosion-proof valve transferred by the suction and transfer assembly 4 is placed in this placement slot 100. In order to ensure the positional accuracy of the explosion-proof valve, in this embodiment, the workstation platform 1 is also provided with a positioning mechanism for positioning the explosion-proof valve in the placement slot 100.

[0067] Specifically, such asFigure 5 and Figure 6 As shown, in this embodiment, the placement slot 100 has a first limiting stop 101 and a second limiting stop 102. The positioning mechanism includes a first positioning block 11 that can move closer to or further away from the first limiting stop 101, and a second positioning block 13 that can move closer to or further away from the second stop. The first positioning block 11 and the first limiting stop 101 can abut against the side of the explosion-proof valve in the width direction to position the explosion-proof valve in the length direction, and the second positioning block 13 and the second limiting stop 102 can abut against the side of the explosion-proof valve in the length direction to position the explosion-proof valve in the width direction.

[0068] With this configuration, when the explosion-proof valve is placed in the placement slot 100, the movement of the first positioning block 11 and the second positioning block 13 can cause the first positioning block 11 and the first limiting stop 101 to abut against the side of the explosion-proof valve in the width direction, and the second positioning block 13 and the second limiting stop 102 to abut against the side of the explosion-proof valve in the length direction. This allows for better positioning of the explosion-proof valve in both the length and width directions.

[0069] In practical implementation, the workstation platform 1 is equipped with a second linear drive device 12 and a third linear drive device 14. A first positioning block 11 is connected to the power output end of the second linear drive device 12, and a second positioning block 13 is connected to the power output end of the third linear drive device 14. Driven by the second linear drive device 12, the first positioning block 11 moves along the length of the explosion-proof valve towards the first limiting stop 101, so that both the first positioning block 11 and the first limiting stop 101 abut against the side of the explosion-proof valve in the width direction. Driven by the third linear drive device 14, the second positioning block 13 moves along the width of the explosion-proof valve towards the second limiting stop 102, and both the second positioning block 13 and the second limiting stop 102 abut against the side of the explosion-proof valve in the length direction, thereby achieving precise positioning of the explosion-proof valve.

[0070] It is worth noting that the second linear drive device 12 and the third linear drive device 14 mentioned above preferably adopt a slide cylinder, which is technically mature, has a small size, and is conducive to the compact design of the equipment.

[0071] In addition, in this embodiment, a detection device for detecting defects in explosion-proof valves placed in the placement tank 100 is also provided on the tooling platform, and an NG (Not From Good) bin 15 is also provided on the tooling platform for collecting unqualified explosion-proof valves transferred to the tooling platform. The detection device can detect defects in the explosion-proof valves. When an unqualified explosion-proof valve is detected, the vacuum adsorption unit 43 above the corresponding placement tank 100 transfers the unqualified explosion-proof valve from the placement tank 100 to the NG bin 15.

[0072] It is worth noting that the aforementioned material detection and testing device may be, for example, a CCD camera or laser detection equipment, which are existing technologies.

[0073] As a preferred embodiment, in this embodiment, such as Figure 1 and Figure 7 As shown, the suction and transfer components 4 are arranged in two opposite groups, and the multiple storage bins 23 in the storage bin component 2 move alternately to the loading position in pairs. Correspondingly, the lifting components 3 are also provided for the two storage bins 23 at the corresponding loading positions. This arrangement further improves the loading efficiency of the explosion-proof valve.

[0074] In this embodiment, the explosion-proof valve feeding device is used in practice. The explosion-proof valves contained in multiple storage bins 23 are driven by the horizontal drive device 21, causing the multiple storage bins 23 to move alternately to the feeding position along the first direction. The lifting member located at the bottom of the storage bin 23 is driven by the lifting drive device to lift the multiple explosion-proof valves to the preset position.

[0075] Next, the two lifting drive devices 42 drive the corresponding vacuum adsorption units 43 to approach the preset positions. One vacuum adsorption unit 43 picks up the top-level explosion-proof valve among multiple explosion-proof valves, while the other vacuum adsorption unit 43 picks up the explosion-proof valve in the placement tank 100 (when the material is initially loaded, there are no explosion-proof valves in the placement tank 100; in this case, the corresponding vacuum adsorption unit 43 performs an air suction operation). Then, driven by the two lifting drive devices 42, both vacuum adsorption units 43 move upward to the designated positions.

[0076] Next, driven by the first linear drive device 41, the mounting plate 401 moves along the second direction, causing the vacuum adsorption unit 43 at the corresponding loading position and the vacuum adsorption unit 43 above the corresponding placement tank 100 to move synchronously. For ease of description, the two vacuum adsorption units 43 are referred to as the first vacuum adsorption unit and the second vacuum adsorption unit, respectively. That is, as the mounting plate 401 moves along the second direction, the first and second vacuum adsorption units move synchronously along the second direction. At this time, the explosion-proof valve picked up from the preset position is moved to the top of the placement tank 100 via the movement of the first vacuum adsorption unit, and the explosion-proof valve picked up from the placement tank is moved to the top of the designated position for the next process via the second vacuum adsorption unit.

[0077] Driven by two lifting drive devices 42, the corresponding two vacuum adsorption units 43 move downwards. At this time, the explosion-proof valve located above the placement slot 100 is placed in the placement slot 100, and the explosion-proof valve above the designated position is placed in the designated position. Then, the vacuum adsorption unit 43 moves upwards to reset, and the mounting plate 401 moves in the opposite direction to reset. This completes one feeding of the explosion-proof valve, and by repeating the above actions, continuous feeding of the explosion-proof valve can be achieved.

[0078] The explosion-proof valve feeding device of this embodiment not only has a simple structure, which helps reduce the manufacturing cost and maintenance of the equipment, but also has a compact structure, which helps reduce the space occupied by the equipment.
