Description

Technical Field

[0001] This application relates to the field of battery manufacturing equipment technology, and in particular to a switch cover device and an oven. Background Technology

[0002] In precision industrial fields such as lithium battery manufacturing, clamshell ovens are widely used due to their strong sealing and stable temperature control. These ovens typically employ a pivot-connected upper and lower chamber structure, requiring frequent opening for maintenance and material handling.

[0003] In related technologies, when opening the lid of a clamshell oven, the operator needs to manually complete the unlocking, driving, and locking processes step by step, which is inefficient and prone to errors. The lack of safety verification when opening and closing the lid results in weak safety protection during the opening and closing process, leading to low operating efficiency and reliability of the oven. Utility Model Content

[0004] To address or partially address the problems existing in related technologies, this application provides a lid opening and closing device and an oven, which can perform multiple safety verifications during the opening or closing process of the oven lid, thereby improving the operating efficiency, safety and reliability of the oven.

[0005] The first aspect of this application provides a cover opening and closing device, comprising: An actuator, the fixed end of which is connected to the lower chamber and the upper chamber of the oven respectively, is used to drive the upper chamber to move relative to the lower chamber. A locking mechanism is connected between the lower housing and the upper housing to lock the upper housing and the lower housing in an open or closed state. A sensing component is used to sense the position signals of the actuator and the locking mechanism; A control component, electrically connected to the sensing component, the actuator, and the locking mechanism, is used to control the operation of the actuator and the locking mechanism based on the sensing signal from the sensing component.

[0006] In one embodiment, the actuator includes a drive body and a telescopic rod that extends and retracts relative to the drive body, with the fixed end located on the drive body and the movable end located on the telescopic rod; the drive body is fixed to the lower housing, and the telescopic rod is connected to the upper housing.

[0007] In one embodiment, the locking mechanism includes a locking body and a support rod movable relative to the locking body, the locking body being disposed in the lower housing and the support rod being connected to the upper housing; The locking body is provided with a locking drive and a first locking member, and the support rod is provided with a first locking part and a second locking part. When the box is in the closed state, the locking drive drives the first locking member to lock with the first locking part. When the box is in the open state, the locking drive drives the first locking member to lock with the second locking part.

[0008] In one embodiment, the sensing component includes a first sensor and a second sensor; the first sensor is used to sense the position signal of the telescopic rod, and the second sensor is used to sense the position signal of the first locking member. The control component is configured to: control the locking drive to operate based on the cover opening sensing signal of the first sensor, so that the first locking member locks with the second locking part; or control the locking drive to operate based on the cover closing sensing signal of the first sensor, so that the first locking member locks with the first locking part.

[0009] In one embodiment, the locking body is provided with a second locking member, and the support rod is provided with a third locking part and a fourth locking part; When the upper and lower housings are in the closed state, the second locking member is used to lock with the third locking part; when the upper and lower housings are in the open state, the second locking member is used to lock with the fourth locking part.

[0010] In one embodiment, the sensing component further includes a third sensor for sensing the position signal of the second locking member; the control component is configured to verify whether the upper housing is in a safe open or safe closed state based on the sensing signals of the first, second, and third sensors.

[0011] In one embodiment, the first locking member and the second locking member are pins, and the first locking part, the second locking part, the third locking part and the fourth locking part are locking holes formed in the support rod; the pins are inserted into the locking holes.

[0012] In one embodiment, the system further includes a control component electrically connected to the control component, which is disposed on the lower housing. The control component includes a first control unit and a second control unit. The first control unit is used to control the operation of the actuator after the locking mechanism is unlocked, and the second control unit is used to control the operation of the locking mechanism after the housing has completed opening or closing.

[0013] In one embodiment, the first control unit includes a speed control valve for controlling the opening speed of the upper box; the control unit also includes a display unit for displaying the running direction of the upper box when it is opened or closed.

[0014] A second aspect of this application provides an oven, comprising: The housing includes an upper housing and a lower housing that are pivotally connected; The upper housing and the lower housing are provided with the opening and closing cover device as described in the first aspect above.

[0015] The technical solution provided in this application may include the following beneficial effects: The opening and closing device provided in this application automatically opens and closes the oven lid by driving the upper chamber to rotate smoothly around a pivot axis via an actuator. The locking mechanism, through the cooperation of a support rod and a locking body, automatically locks when the lid is fully open or closed, preventing accidental movement or falling of the upper chamber. A sensing component monitors the actuator's stroke and locking status in real time and feeds signals back to the control component. The control component coordinates the timing of the opening and locking actions, ensuring that the locking mechanism is fully unlocked before opening and immediately locked after the lid is fully open, forming a closed-loop control. This design significantly improves operational safety, avoids the risk of accidental lid closure due to mechanical failure, improves the oven's operating efficiency and safety, and meets the protection requirements of lithium battery production.

[0016] Furthermore, in the technical solution of this application, the control component verifies whether the upper chamber is in a safe open or safe closed state based on the sensing signals of the first, second, and third sensors. By simultaneously collecting the three detection signals from the first, second, and third sensors, the controller performs logical judgment on the three signals. Only when automatic locking is completed and manual secondary locking is ready is it determined to be in a safe open state (or reverse verification of the closed state), thus forming a cross-verification of electrical, mechanical, and manual processes. This avoids the risk of misjudgment due to single sensor failure, mechanical jamming, or human error, further making the maintenance of the oven safer and more reliable.

[0026] In related technologies, when opening the lid of a clamshell oven, the operator needs to manually complete the unlocking, driving, and locking processes step by step, which is inefficient and prone to errors. Furthermore, the lack of safety verification during lid opening and closing results in weak safety protection during these processes, leading to low operating efficiency and reliability of the oven. To address these problems, this application provides a lid opening / closing device and an oven that can implement multiple safety verifications during the lid opening or closing process, thereby improving the oven's operating efficiency, safety, and reliability.

[0027] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0028] Figure 1 This is a schematic diagram of the structure of the opening and closing cover device installed in the oven, as shown in the embodiment of this application.

[0029] See Figure 1This application provides a cover opening and closing device 100, which includes an actuator 110, a locking mechanism 120, a sensing component, and a control component. The fixed end and the movable end of the actuator 110 are respectively connected to the lower chamber 210 and the upper chamber 220 of the oven 200, and are used to drive the upper chamber 220 to move relative to the lower chamber 210. The locking mechanism 120 is connected between the lower chamber 210 and the upper chamber 220, and is used to lock the upper chamber 220 and the lower chamber 210 to an open state or a closed state. The sensing component is used to sense the position signals of the actuator 110 and the locking mechanism 120. The control component is electrically connected to the sensing component, the actuator 110, and the locking mechanism 120, and is used to control the operation of the actuator 110 and the locking mechanism 120 based on the sensing signals of the sensing component.

[0030] The cover opening and closing device 100 provided in this application drives the upper chamber 220 to rotate smoothly around a pivot axis via the actuator 110, thereby automating the opening and closing of the oven 200 cover. The locking mechanism 120, through the cooperation of the support rod 122 and the locking body 121, automatically locks when the cover is opened or closed, preventing the upper chamber 220 from moving or falling accidentally. The sensing component monitors the stroke and locking status of the actuator 110 in real time and feeds the signal back to the control component. The control component coordinates the timing of the cover opening and locking actions, ensuring that the locking mechanism 120 is fully unlocked before the cover is opened and immediately locked after the cover is opened, forming a closed-loop control. This design significantly improves operational safety, avoids the risk of accidental cover closure due to insufficient air pressure or mechanical failure, improves the operating efficiency and safety of the oven 200, and meets the protection requirements of lithium battery production.

[0031] See Figure 1 and Figure 2 In some embodiments, the actuator 110 includes a drive body 111 and a telescopic rod 112 that extends and retracts relative to the drive body 111. The fixed end is located on the drive body 111, and the movable end is located on the telescopic rod 112. The drive body 111 is fixed to the lower housing 210, and the telescopic rod 112 is connected to the upper housing 220. In some embodiments, the actuator 110 may be a telescopic cylinder. The fixed end is located in the cylinder body of the telescopic cylinder. The cylinder body is fixed to the side of the lower housing 210 via a first lower mounting seat 1101. The end of the telescopic rod 112 away from the cylinder body is movably connected (e.g., hinged) to the side of the upper housing 220 via a first upper mounting seat. The telescopic cylinder pushes the upper housing 220 to rotate and open around a pivot axis through its telescopic movement.

[0032] In this application, the telescopic cylinder, through the rigid fixation between the cylinder body and the lower housing 210 and the movable connection between the telescopic rod 112 and the upper housing 220, efficiently converts the linear telescopic motion into the rotational opening and closing action of the upper housing 220. The first lower mounting seat 1101 and the first upper mounting seat respectively resolve the lateral load on the cylinder caused by the deformation of the housing, ensuring that the cylinder only bears the axial force, which can improve the durability of the actuator 110. The overall structure is compactly integrated into the side of the housing, realizing stable and reliable drive force transmission in a limited space. It is especially suitable for frequent opening operations in the environment of high-temperature oven 200, significantly reducing the risk of mechanical failure and ensuring the stability of drive force transmission.

[0033] In some embodiments, the locking mechanism 120 includes a locking body 121 and a support rod 122 movable relative to the locking body 121. The locking body 121 is disposed in the lower housing 210, and the support rod 122 is connected to the upper housing 220. The locking body 121 is mounted to the lower housing 210 via a second lower mounting seat 1201, and one end of the support rod 122 away from the locking body 121 is movably connected to the side of the upper housing 220 via a second upper mounting seat 1202. The locking body 121 includes a locking drive member 1211 and a first locking member 1212. The support rod 122 has a first locking portion and a second locking portion. When the housing is in a closed state, the locking drive member 1211 drives the first locking member 1212 to lock with the first locking portion. When the housing is in an open state, the locking drive member 1211 drives the first locking member 1212 to lock with the second locking portion.

[0034] See Figure 2 and Figure 3 The first locking member 1212 can be a first plug-in member, such as a pin. The locking body 121 is provided with a first support part 1203. The first support part 1203 has a through hole along the radial direction of the support rod 122 for the first plug-in member to pass through. The locking drive member 1211 can be a cylinder or a motor. The first locking part and the second locking part are respectively the first locking hole and the second locking hole that are aligned with the first plug-in member when closing and opening. The cylinder or motor drives the first plug-in member to move horizontally in the through hole of the first support part 1203. When the through hole is aligned with the first locking hole, the first plug-in member can be plugged into the first locking hole. When the through hole is aligned with the second locking hole, the first plug-in member can be plugged into the second locking hole.

[0035] The locking mechanism 120 of this application achieves adaptive adjustment of the locking position through linkage between the support rod 122 and the upper housing 220, automatically aligning with the corresponding locking holes during the opening and closing of the housing. The locking drive component 1211 drives the pin to precisely insert into the locking holes at different positions of the support rod 122, forming a mechanical interlock that strictly corresponds to the state of the housing. The automatic horizontal movement locking mechanism of the first connector eliminates manual intervention, ensuring fast and reliable locking action and effectively preventing the housing cover from accidentally opening or closing due to vibration or load changes. The dual locking hole layout allows the support rod 122 to withstand the housing load in both open and closed states, significantly improving the stability of equipment operation and the safety of personnel operation. In addition, in the open state, after the first connector is inserted into the second locking hole, the support rod 122 can support the upper housing 220, and together with the telescopic rod 112 of the actuator 110, it achieves double support for the upper housing 220, effectively preventing the upper housing 220 from accidentally falling.

[0036] In some embodiments, the sensing component includes a first sensor 1111 and a second sensor 1214; the first sensor 1111 is used to sense the position signal of the telescopic rod 112, and the second sensor 1214 is used to sense the position signal of the first locking member 1212; the control component is configured to: control the locking drive 1211 to operate based on the cover opening sensing signal of the first sensor 1111, so that the first locking member 1212 is locked with the second locking part; or control the locking drive 1211 to operate based on the cover closing sensing signal of the first sensor 1111, so that the first locking member 1212 is locked with the first locking part.

[0037] See Figure 1 In this embodiment, the first sensing element 1111 can be a cylinder magnetic sensor, and there are two of them, namely cylinder magnetic sensor 1111a and cylinder magnetic sensor 1111b. Cylinder magnetic sensor 1111a and cylinder magnetic sensor 1111b are used to monitor the fully extended position and the fully retracted position of the telescopic rod 112, respectively. They can be set at the upper end and the lower end inside the cylinder, but are not limited thereto.

[0038] See Figure 2 The second sensing element 1214 can be a first pin position sensor, and there are two of them, namely the second sensing element 1214a and the second sensing element 1214b, which are used to monitor the position of the first pin inserted into the corresponding locking hole and the position of the first pin disengaged from the corresponding locking hole, respectively. Based on the cover opening signal of the cylinder magnetic sensor 1111a, the control component activates the locking drive 12311 to lock the first pin to the corresponding locking hole of the support rod 122.

[0039] In this application, the first sensor 1111 accurately captures the opening / closing limit position of the telescopic rod 112 and triggers a signal to directly drive the locking mechanism 120 to respond; the second sensor 1214 provides real-time feedback on the locking / unlocking status of the first connector, achieving synchronization between execution and feedback. The controller uses the position of the telescopic rod 112 as the starting point command (activating the upper locking when the cover is fully open, and activating the lower locking when the cover is fully closed), and then uses the position of the first connector as the verification for action completion. The dual signal linkage can effectively avoid the risk of false triggering, ensuring that the upper housing 220 is locked only when fully open or closed, avoiding safety accidents caused by misalignment of the action sequence of the actuator 110 and the locking mechanism 120, thereby improving the safety of opening and closing the cover.

[0040] See Figure 3 and Figure 4 In some embodiments, the locking body 121 is provided with a second locking member 1213, and the locking body 121 is also provided with a second support portion 1204. The second support portion 1204 has a through hole along the radial direction of the support rod 122 for the second plug-in member to pass through. The support rod 122 is provided with a third locking portion and a fourth locking portion. When the upper box 220 and the lower box 210 are in the closed state, the second locking member 1213 is used to lock with the third locking portion. When the upper box 220 and the lower box 210 are in the open state, the second locking member 1213 is used to lock with the fourth locking portion. The second locking member 1213 can be a second plug-in member, such as a pin. The third locking part and the fourth locking part are the third locking hole and the fourth locking hole added to the middle of the support rod 122, respectively. The third locking hole is close to the upper housing 220 and the fourth locking hole is close to the lower housing 210. When the device is closed, the operator operates the second plug-in member to insert into the third locking part after passing through the through hole of the second support part 1204. When the device is open, it passes through the through hole of the second support part 1204 and is inserted into the fourth locking part, and then the locking is completed by manual operation.

[0041] In this application, the second connector serves as a redundant locking mechanism 120. After the upper housing 220 is fully opened or closed, manual intervention completes a secondary locking, forming a dual mechanical lock with the first connector, providing complementary safety protection for the first connector. The third and fourth locking holes are precisely matched to the force points in the open and closed states, ensuring that the second connector withstands pressure in the closed state and shear force in the open state, maximizing the mechanical locking strength. This embodiment avoids the risk of electrical system failure of the first connector through manual physical locking, making it particularly suitable for the extreme safety requirements under the high-temperature conditions of the 200°C oven, forming a safety protection mechanism that combines automatic and manual control.

[0042] In some embodiments, the sensing assembly further includes a third sensor 1215, which is used to sense the position signal of the second locking member 1213. The controller is configured to verify whether the upper housing 220 is in a safe open or safe closed state based on the sensing signals of the first sensor, the second sensor 1214, and the third sensor 1215. The third sensor 1215 can be a second connector position sensor, and there are two of them, namely third sensors 1215a and 1215b, which are used to monitor the position of the second connector inserted into the third locking hole or the fourth locking hole, and the position of it disengaged from the third locking hole or the fourth locking hole, respectively.

[0043] In this application, the specific positions of the first sensor 1111, the second sensor 1214, and the third sensor 1215 can be set according to actual needs, and this application does not limit this. This application synchronously collects three detection signals from the first sensor 1111, the second sensor 1214, and the third sensor 1215, requiring all locking levels to be physically in place before the safety alarm is released. The controller performs logical judgment on the three detection signals, determining a safe open state (or reverse verification of the closed state) only when automatic locking is complete and manual secondary locking is ready, thus forming a cross-verification of electrical, mechanical, and manual processes. This avoids the risk of misjudgment due to single sensor failure, mechanical jamming, or human error, making the maintenance of the oven 200 safer and more reliable.

[0044] See Figure 5 In some embodiments, the cover opening and closing device 100 further includes a control component 130 electrically connected to the control component, which is disposed in the lower housing 210. The control component 130 includes a first control part 131 and a second control part 132. The first control part 131 is used to control the operation of the actuator 110 after the locking mechanism 120 is unlocked, and the second control part 132 is used to control the operation of the locking mechanism 120 after the housing has completed opening or closing.

[0045] In this application, the control component 130 is installed on the outer wall of the lower housing 210. The first control unit 131 includes a manual valve and a speed control valve. The manual valve is used to control the start of the actuator 110, and the speed control valve is used to control the operating speed of the actuator 110, such as the extension and retraction speed of the telescopic cylinder, thereby controlling the opening or closing speed of the upper housing 220. The speed control valve can be a pilot-operated speed control valve, connected in series in the air path of the telescopic cylinder of the actuator 110, and controls the opening speed by adjusting the airflow. The second control unit 132 is a first connector control button, used to control the locking or unlocking of the first connector.

[0046] The control unit 130 also includes a display unit, which is used to display the running direction of the upper housing 220 when it is opened or closed. Specifically, the display unit includes a lifting indicator panel, which can use dual-color LED indicators, such as a green light indicating that the lid is open and a red light indicating that the lid is closed; or it can use bidirectional arrow indicators, such as an upward arrow indicating that the lid is open and a downward arrow indicating that the lid is closed.

[0047] In this application, the opening actuator 110 can only be activated via a manual valve when the locking mechanism 120 is fully unlocked. The speed control valve infinitely adjusts the cylinder speed, simultaneously optimizing the smoothness of opening and impact protection. The second control unit 132 is designed to activate only after the housing is in position, ensuring that the locking command matches the physical state. The display unit provides real-time feedback on the direction of movement, converting the mechanical status into a visual signal. This simplifies the operation process while providing dual protection for work safety in high-risk environments through hardware interlocking and visual cues.

[0048] In this application, during the opening process, the first connector button is operated to unlock the cover. After the sensor confirms that the pin has been pulled out, the manual valve drives the telescopic cylinder to slowly lift the upper housing 220. The support rod 122 moves upward simultaneously. When the support rod 122 is in place, the sensor and the cylinder magnetic sensor jointly verify that the cover is in place, and automatically trigger the first connector to insert into the second locking hole above the support rod 122 to complete the first layer of locking. Then, the second connector is manually inserted into the locking hole in the middle of the support rod 122. After the sensor verifies, the cover opening alarm is deactivated, forming a double safety protection. During the closing process, the second connector is first pulled out, then the first pin button is operated to retract the first connector, and then the manual valve is operated to slowly pull back the upper housing 220 until it is closed. After the upper housing 220 is closed, the three signals of the second connector pull-out sensor, the first pin position sensor, and the cylinder magnetic sensor are verified simultaneously. After all the verifications are passed, the closing alarm is deactivated, realizing three-layer closed-loop verification. This application ensures the reliability of the opening / closing action and the safety of operation through timing control and human-machine interaction. The opening and closing cover device 100 of this application has been described above. Correspondingly, this application also provides an oven 200.

[0049] See Figure 1 The oven 200 includes a box body, which includes an upper box body 220 and a lower box body 210 that are pivotally connected. A switch cover device 100 as described in any of the above embodiments is provided between the upper box body 220 and the lower box body 210.

[0050] The oven 200 of this application can be a clamshell oven, which can be a gravure printing machine for producing lithium batteries. Specifically, the oven 200 includes a lower chamber 210 and an upper chamber 220. The lower chamber 210 is fixedly installed, and the upper chamber 220 and the lower chamber 210 are connected on one side by a pivot shaft. The upper chamber 220 can be flipped relative to the lower chamber 210, and the upper chamber 220 is also called a cover. A cover opening / closing device 100 is provided on the opening / closing side of the lower chamber 210 and the upper chamber 220. The fixed end of the actuator 110 is fixed to the side of the lower chamber 210 of the oven 200, and the moving end is connected to the upper chamber 220, driving the upper chamber 220 to flip around the pivot side. The locking body 121 is fixed to the side of the lower housing 210. The lower end of the support rod 122 is connected to the locking body 121, and the upper end is movably connected to the upper housing 220, moving with the upper housing 220.

[0051] The oven provided in this application drives the upper chamber 220 to rotate smoothly around a pivot axis through the actuator 110 of its opening device, thereby realizing the automatic opening and closing of the oven 200 lid. The locking mechanism 120 automatically locks when the lid is opened or closed in place through the cooperation of the support rod 122 and the locking body 121, preventing the upper chamber 220 from moving or falling accidentally. The sensing component monitors the stroke and locking status of the actuator 110 in real time and feeds the signal back to the control component. The control component coordinates the timing of the opening and locking actions to ensure that the locking mechanism 120 is fully unlocked before the lid is opened and immediately locked after the lid is opened in place, forming a closed-loop control. This can improve the operating efficiency and safety of the oven 200 and meet the protection requirements of lithium battery production.
