Abstract
Description
Technical Field
[0001] The present application relates to the technical field of thermal transfer equipment, and in particular to a heat press. Background Art
[0002] A heat press is a device that can transfer or bake various colorful icons, landscape patterns, etc. onto substrates such as cotton, linen, porcelain plates or metal plates. However, in actual use, traditional heat presses still have some shortcomings. For example, during the heat pressing process, traditional heat presses use self-locking transmission mechanisms (such as screws, strip torsion springs, etc.) or mechanical locks (such as mechanical latch locks, electromagnetic latch locks, etc.) to achieve hard limit when pressing down, so as to limit the relative position of the heat press and the workbench, and improve the work efficiency and reliability of the heat pressing process. However, at the same time, when the heat press suddenly loses power for any reason (it can be manually shut down, it can also be a power outage, or it can be an error), the mechanical locks and other mechanisms in the heat press will also be completely locked and cannot be manually unlocked, making the safety of the heat press low. Utility Model Content
[0003] The utility model aims to provide a hot press machine, in which an electromagnet is arranged. The electromagnet can be used to limit the relative position of the hot pressing part and the workbench after power is turned on, and can also be automatically unlocked after power is turned off, so that the hot press machine has higher reliability and safety.
[0004] An embodiment of the present application provides a hot press, which includes a workbench, which is used to carry a workpiece to be processed; a hot pressing piece, which is arranged opposite to the workbench and is used to process the workpiece to be processed on the workbench; a supporting assembly, on which the workbench is arranged; a rotating assembly, on which the hot pressing piece is arranged, and the rotating assembly is rotatably connected to the supporting assembly; and an electromagnet, which is arranged on the supporting assembly and is used to adsorb the rotating assembly after being energized to limit the relative position of the hot pressing piece and the workbench.
[0005] In one possible implementation, the hot press also includes a retractable gas rod, the two ends of which are rotatably connected to the support assembly and the rotating assembly respectively. When the electromagnet does not generate adsorption force on the rotating assembly, the length of the gas rod is extended to drive the hot pressing part to move away from the workbench.
[0006] In a possible implementation, the support assembly includes a base and a support arm, the base is connected to one end of the support arm, and the workbench is disposed on the base, and the rotating assembly is rotatably connected to the other end of the support arm.
[0007] In one possible implementation, the rotating assembly includes a first movable arm, one end of which is rotatably connected to the support arm, and the hot pressing piece is arranged at the other end of the first movable arm; the rotating assembly also includes a second movable arm, one end of which is rotatably connected to the support arm, and the second movable arm is also transmission-connected to the first movable arm; the electromagnet is fixedly connected to the support arm and is arranged corresponding to the second movable arm. When the first current is passed through the electromagnet, the electromagnet is used to adsorb the second movable arm to limit the rotation of the second movable arm relative to the support arm, thereby limiting the rotation of the first movable arm relative to the support arm, so as to limit the relative position of the hot pressing piece and the workbench.
[0008] In one possible implementation, the first movable arm includes a protruding first locking portion, and the first locking portion has a locking surface; the second movable arm has a second locking portion at the end near the first movable arm; when the electromagnet is passed with a first current, the electromagnet and the second movable arm are magnetically attracted and contacted, and the second locking portion abuts the locking surface, so as to limit the rotation of the first movable arm relative to the support arm, thereby limiting the relative position of the hot pressing part and the workbench; when the first current is disconnected, the electromagnet is disengaged from the second movable arm, and the second locking portion is disengaged from the locking surface.
[0009] In a possible implementation, the second movable arm has a first end and a second end that are arranged opposite to each other, the first end of the second movable arm is close to the first movable arm and is rotatably connected to the support arm, and the electromagnet is arranged corresponding to the second end of the second movable arm.
[0010] In a possible implementation, the first movable arm is provided with a roller, the roller is mounted on the first clamping portion and is rotatably connected to the first clamping portion, and when the first current is disconnected, the roller rolls and connects to the second movable arm.
[0011] In a possible implementation manner, the roller protrudes relative to the first locking portion.
[0012] In a possible implementation, a side surface of the second locking portion forms a contact surface, and when the first current is disconnected, the roller contacts and rolls to connect the contact surface, and the contact surface is a concave curved surface.
[0013] In one possible implementation, the hot press also includes a retractable gas rod, both ends of which are rotatably connected to the first movable arm and the support arm respectively. When the electromagnet is passed with a first current, the length of the gas rod contracts; when the first current is disconnected, the length of the gas rod extends and pushes the first movable arm to rotate relative to the support arm, thereby driving the hot pressing part to move away from the workbench.
[0014] In one possible implementation, the hot press also includes a driving member connected to the support arm. After the electromagnet adsorbs the rotating component, the driving member is used to drive the support arm to move relative to the base in its height direction to drive the hot press part to move toward the workbench.
[0015] The embodiment of the present application arranges an electromagnet in the heat press. The electromagnet can be used to adsorb the rotating component after power is turned on to limit the rotation process of the rotating component relative to the supporting component, thereby limiting the relative position of the hot-pressed part and the workbench. The electromagnet can also release the rotating component and unlock the heat press when the heat press is pressed into place (or during pressing) due to power failure for any reason (it can be a manual shutdown, a power outage, or an error), thereby avoiding the problem of not being able to unlock in time when pressing on a person's hand or pressing on the hot-stamped object for a timeout, thereby improving the reliability and safety of the heat press.

[0029] See also Figure 1 and Figure 2 , Figure 1 1 is a schematic diagram of the structure of a heat press 100 in an open state provided in an embodiment of the present application. Figure 2 It is a schematic structural diagram of a hot press machine 100 in a closed state provided in an embodiment of the present application.
[0030] The hot press 100 may include a hot press 11, a workbench 12, a support assembly 20 and a rotating assembly 30. The hot press 11 may be arranged opposite to the workbench 12. The workbench 12 may be arranged on the support assembly 20. The hot press 11 may be arranged on the rotating assembly 30, and the rotating assembly 30 may be rotatably connected to the support assembly 20. The hot press 100 may be used to transfer or bake the pattern on the transfer paper onto the substrate. The workbench 12 may be used to carry workpieces such as substrates and transfer paper waiting to be processed. The hot press 11 may be used to process the workpieces to be processed on the workbench 12. For example, the hot press 11 may be used to contact the transfer paper and the substrate on the workbench 12, and apply pressure to the transfer paper and the substrate while heating them to process the substrate, so as to realize the hot pressing function of the hot press 100. It is understandable that in other embodiments, the processing process of the substrate by the hot press 100 may also be only one of heating or pressurizing, and the present application does not limit this. In other embodiments, the hot pressing member 11 may also be referred to as a hot pressing plate, etc., and this application does not limit this.
[0031] See also Figure 3 and Figure 6 , Figure 3 yes Figure 1 The partial structural diagram of the hot press 100 shown in FIG. Figure 6 yes Figure 2 The schematic diagram of the partial structure of the hot press 100 shown in FIG. Figure 3 yes Figure 1 The heat press machine 100 shown is a schematic structural diagram with the outer shell 13 removed. Figure 6 yes Figure 2 The heat press machine 100 shown is a schematic structural diagram with the housing 13 removed.
[0032] Exemplarily, the support assembly 20 may include a support arm 21 and a base 22, the base 22 is connected to one end of the support arm 21, and the workbench 12 may be disposed on the base 22, and the rotating assembly 30 may be rotatably connected to the other end of the support arm 21. The support assembly 20 may provide hardness support for the hot press 100, and the support arm 21 may be vertical or approximately vertical to the base 22. For example, the support arm 21 and the base 22 may be approximately L-shaped, which can improve the support force of the support arm 21 on the rotating assembly 30 and the base 22 on the workbench 12, and can also improve the overall compressive strength and impact strength of the hot press 100, effectively avoiding the phenomenon that the workbench 12 and the substrate slip when the hot press 11 applies force to the substrate, thereby improving the reliability of the hot press 100. In some examples, the support arm 21 may have a first end 211 and a second end 212 that are oppositely disposed, the base 22 may be connected to the first end 211 of the support arm 21 , and at least a portion of the rotating assembly 30 may be rotatably connected to the second end 212 of the support arm 21 .
[0033] In some embodiments, the rotating assembly 30 may include a first movable arm 31 , one end of which may be rotatably connected to the second end 212 of the support arm 21 , and the hot pressing piece 11 may be disposed at the other end of the first movable arm 31 .
[0034] By setting the first movable arm 31 to be able to rotate relative to the support arm 21, it can be used to drive the movement of the hot press 11, so that the hot press 11 can rotate relative to the workbench 12, and the size of the space and angle between the hot press 11 and the workbench 12 can be adaptively adjusted according to different working states of the hot press 100. For example, when it is necessary to place a substrate on the workbench 12 or take a substrate out of the workbench 12, the first movable arm 31 can be rotated along the side away from the workbench 12 to drive the hot press 11 to move away from the workbench 12, so as to provide a larger operating space for placing and taking out the substrate; when the hot press 11 needs to contact the substrate to realize the hot pressing function of the hot press 100, the first movable arm 31 can also be rotated toward the side close to the workbench 12 to drive the hot press 11 to move toward the direction close to the workbench 12.
[0035] By setting the first movable arm 31 to have different positional relationships relative to the support arm 21 when the hot press machine 100 is in different working processes, the flexibility and convenience of using the hot press machine 100 can be effectively improved. In addition, by driving the hot press member 11 to move through the first movable arm 31, it is also possible to avoid problems such as users being easily burned when directly contacting the hot press member 11 to change its relative position with the workbench 12, and effectively improve the safety and reliability of using the hot press machine 100.
[0036] The heat press 100 may also include a telescopically arranged gas rod 40, and the two ends of the gas rod 40 may be rotatably connected to the support assembly 20 and the rotating assembly 30, respectively. In some examples, one end of the gas rod 40 may be rotatably connected to the first movable arm 31, and the other end of the gas rod 40 may be rotatably connected to the first end 211 of the support arm 21. It can be understood that the heat press 100 may include a pressing process, a hot pressing process, and a lifting process. For the gas rod 40, during the pressing process, the user can apply a certain force to press the first movable arm 31 to rotate it. At this time, the gas rod 40 is compressed, and the length of the gas rod 40 shrinks. It can be considered that the compression amount of the gas rod 40 is increasing. When the external force is evacuated, the potential energy of the compressed air can be converted into mechanical energy output in the gas rod 40 to push the first movable arm 31 upward. The first movable arm 31 will be compressed under the action of the gravity of the first movable arm 31 and the hot pressing piece 11 before the pressing process, and the first movable arm 31 will tend to move upward due to the restoring force of the gas rod 40, and one end of the first movable arm 31 is rotatably connected to the support arm 21. Therefore, when the gas rod 40, the first movable arm 31 and the hot pressing piece 11 are in a state of dynamic equilibrium, the hot pressing piece 11 and the workbench 12 will maintain a certain angle and remain relatively still, that is, the hot pressing piece 11 can tilt outward relative to the workbench 12. In the embodiment of the present application, the position of the first movable arm 31 relative to the support arm 21 before the pressing process when no external force is applied to the first movable arm 31 is recorded as the first position of the first movable arm 31 or the initial position of the first movable arm 31. At this time, it can also be recorded as the hot press 100 is in an open state. At this time, the space between the hot pressing piece 11 and the workbench 12 is the largest, which can provide a larger operating space for placing the substrate.
[0037] During the pressing process, after an external force is applied to the first movable arm 31 to offset the influence of the restoring force of the gas rod 40, the first movable arm 31 will move toward the side close to the workbench 12, and the compression of the gas rod 40 will further increase under the action of pressure. The rotation direction of the first movable arm 31 relative to the support arm 21 when it moves toward the side close to the workbench 12 can be recorded as the first rotation direction A1. During the rotation of the first movable arm 31 along the first rotation direction A1, the angle between the hot pressing part 11 and the workbench 12 gradually decreases until the hot pressing part 11 can be arranged relative to the workbench 12, which can also be approximately understood as the hot pressing part 11 and the workbench 12 are parallel to each other. At this time, it is beneficial to make the substrate more evenly heated and stressed in the subsequent hot pressing process, and the hot pressing effect is better. It can also avoid the problem that when the hot pressing part is tilted relative to the workbench 12 during the hot pressing process, the boundary of the printed or baked pattern on the substrate is blurred or the overall displacement relative to the target position, and can improve the reliability of the hot pressing process.
[0038] When the hot pressing piece 11 and the workbench 12 are arranged relative to each other in the embodiment of the present application, the position of the first movable arm 31 relative to the support arm 21 is recorded as the second position of the first movable arm 31 relative to the support arm 21. When the first movable arm 31 is at the second position, the hot press 100 can be regarded as being in a closed state. The pressing process can also be regarded as the process of the first movable arm 31 moving from the first position to the second position, and the lifting process can also be regarded as the process of the first movable arm 31 moving from the second position to the first position. During the hot pressing process, the first movable arm 31 is always at the second position relative to the support arm 21. In other words, the angle between the first movable arm 31 and the support arm 21 remains unchanged, and the relative position relationship between the hot pressing piece 11 and the workbench 12, such as the distance between the hot pressing piece 11 and the workbench 12, is not limited.
[0039] In some embodiments, the connection point between the gas rod 40 and the first movable arm 31 can be arranged close to the hot pressing part 11 relative to the support arm 21. The connection point between the gas rod 40 and the first movable arm 31 can also be understood as the force application point of the gas rod 40 on the first movable arm 31. By setting the force application point away from the rotation center of the first movable arm 31, it is beneficial to increase the length of the power arm, so that the pushing effect of the gas rod 40 on the first movable arm 31 is more effective, and the movement time of the first movable arm 31 returning to its original position during the lifting process can be shortened, thereby improving work efficiency.
[0040] In some embodiments, when the first movable arm 31 is located at the second position, the gas rod 40 contracts to the minimum length. By reasonably setting the range of the compression amount of the gas rod 40, when the first movable arm 31 is located at the second position, the restoring force of the gas rod 40 is relatively large, and the first movable arm 31 can be prevented from continuing to rotate along the first rotation direction A1 during the pressing process of the hot press 100, thereby driving the hot press 11 to further move toward the direction of the workbench 12, so as to ensure that the hot press 11 can maintain a mutually parallel positional relationship with the workbench 12. In other embodiments, the rotation range of the first movable arm 31 can also be limited by the interaction between other structures in the hot press 11, and this application does not limit this. In addition, during the lifting process of the hot press 100, the large restoring force of the gas rod 40 can give the first movable arm 31 a greater driving force, which is conducive to pushing the first movable arm 31 to rotate relative to the support arm 21 until it returns to the first position, reducing the difficulty of the lifting process of the hot press 100.
[0041] The first movable arm 31 may further include a protruding first locking portion 33, the first locking portion 33 having a locking surface 313, the rotating assembly 30 may further include a second movable arm 32, the second movable arm 32 may be rotatably connected to the support arm 21, and the second movable arm 32 may be transmission-connected to the first movable arm 31, the second movable arm 32 may have a first end 321 and a second end 322 arranged opposite to each other, the first end 321 of the second movable arm 32 may be close to the first movable arm 31 and have a second locking portion 34. The surface of the first movable arm 31 facing the second movable arm 32 may have a first connection surface 311 and a second connection surface 312, the second connection surface 312 may be the surface of the first locking portion 33 facing the second movable arm 32 when the first movable arm 31 is located at the first position, the first locking portion 33 may also have a locking surface 313, the locking surface 313 may connect the first connection surface 311 and the second connection surface 312. When the second locking portion 34 abuts against the locking surface 313, the second locking portion 34 can block the rotation process of the first movable arm 31 to fix the relative position of the first movable arm 31 and the support arm 21. When the second locking portion 34 loses contact with the locking surface 313, the first movable arm 31 can still rotate relative to the support arm 21.
[0042] When the first movable arm 31 moves from the first position to the second position, that is, when the hot press 100 is in the pressing process, the first movable arm 31 will rotate relative to the support arm 21, and the force acting on the first movable arm 31 will act on the second movable arm 32 through the contact portion of the first movable arm 31 and the second movable arm 32, so that the second movable arm 32 can also rotate relative to the support arm 21, and the rotation direction of the second movable arm 32 relative to the support arm 21 can be the same as the rotation direction of the first movable arm 31 relative to the support arm 21, and the rotation direction of the second movable arm 32 is also the first rotation direction A1. When the first movable arm 31 is installed on the support arm 21, the rotation trajectory and rotation center of the first movable arm 31 are certain. By setting the second locking portion 34 to abut the locking surface 313, it can also be considered that an obstacle is set within the trajectory range of the first movable arm 31. The second locking portion 34 will interfere with the locking surface 313, and can block the first movable arm 31 from rotating in the opposite direction of the first rotation direction A1, that is, it blocks the process of the first movable arm 31 opening in the opposite direction under the restoring force of the gas rod 40, so as to achieve the limitation of the position of the first movable arm 31.
[0043] The hot press 100 may further include an electromagnet 50, which is disposed on the support assembly 20 and is used to absorb the rotating assembly 30. The electromagnet 50 can be used to absorb the rotating assembly 30 after being energized to limit the relative position of the hot press 11 and the workbench 12. In the embodiment of the present application, the electromagnet 50 may be fixedly connected to the support arm 21 and disposed corresponding to the second end 322 of the second movable arm 32. When the first current is passed through the electromagnet 50, the electromagnet 50 will generate an adsorption force, magnetically attracted to the second movable arm 32, so as to adsorb and fix the second movable arm 32. When the electromagnet 50 and the second movable arm 32 are completely adsorbed and fit together, the adsorption force generated by the electromagnet 50 will hinder the second movable arm 32 from rotating in the opposite direction of the first rotation direction A1. The electromagnet 50 is located on the rotation trajectory of the second movable arm 32, and it will also prevent the second movable arm 32 from continuing to rotate relative to the support arm 21 in the first rotation direction A1. That is, when the first current is passed through the electromagnet 50, the relative position relationship between the second locking portion 34 and the locking surface 313 can be fixed, thereby locking the position of the first movable arm 31, so that the first movable arm 31 stays at the second position.
[0044] When the first current is disconnected, the electromagnet 50 loses its adsorption force, the second end 322 of the second movable arm 32 can be separated from the lock of the electromagnet 50, the gas rod 40 will extend and give an upward force to the first movable arm 31, and the second movable arm 32 will also be affected by the interaction force of the first movable arm 31, and continue to rotate relative to the support arm 21 in the opposite direction of the first rotation direction A1, the position of the second clamping portion 34 will change accordingly, the second clamping portion 34 will be separated from the clamping surface 313, and the first movable arm 31 will rotate relative to the support arm 21 in the opposite direction of the first rotation direction A1, thereby unlocking the relative position of the first movable arm 31 and the support arm 21, and the first movable arm 31 can return to the first position relative to the support arm 21. Among them, the electromagnet 50 can be magnetically attracted to the second movable arm 32, which can be understood as that the part of the second movable arm 32 corresponding to the electromagnet 50, that is, the second end 322 of the second movable arm 32 is metal, or the second movable arm 32 is made of metal material, or metal is fixedly arranged on the second movable arm 32. This application does not impose any limitation on this.
[0045] In addition, by setting the electromagnet 50 corresponding to the second end 322 of the second movable arm 32, the distance between the first end 321 of the second movable arm 32 and the second end 322 of the second movable arm 32 can be enlarged and effectively act on the second movable arm 32, which is beneficial to improve the effect of the electromagnet 50 and reduce the requirements for the adsorption capacity of the electromagnet 50 during the process of locking the second movable arm 32, which is beneficial to reduce the manufacturing cost and difficulty of the hot press 100.
[0046] like Figure 3, Figure 4 , Figure 5 and Figure 6 As shown, Figure 4 It is a structural schematic diagram of a hot press machine 100 provided in an embodiment of the present application when the first movable arm 31 is located at the third position. Figure 5 It is a structural schematic diagram of a hot press machine 100 provided in an embodiment of the present application when the first movable arm 31 is located at the fourth position.
[0047] Exemplarily, the first movable arm 31 may also be provided with a roller 35, and the roller 35 may be installed on the first clamping portion 33, and rotatably connected to the first clamping portion 33, and when the first current is disconnected, the roller 35 rolls and connects to the second movable arm 32. The first current may be considered to be in an off state during both the pressing process and the lifting process. At this time, the roller 35 is located between the first movable arm 31 and the second movable arm 32. During the pressing process, when an external force presses the first movable arm 31 to rotate relative to the support arm 21 along the first rotation direction A1, or, during the lifting process, when the gas rod 40 pushes the first movable arm 31 to rotate relative to the support arm 21 in the opposite direction of the first rotation direction A1, by providing the roller 35, the roller 35 can be rotatably connected to the second movable arm 32, which can reduce the friction between the first movable arm 31 and the second movable arm 32 during rotation, and the rotation process of the first movable arm 31 is easier, smoother and more labor-saving.
[0048] In some embodiments, the roller 35 can protrude relative to the first locking portion 33, which is beneficial to reducing the contact area between the first locking portion 33 and the second movable arm 32 during the rotation of the first movable arm 31, so that the first movable arm 31 and the second movable arm 32 can be in contact with each other relying on the roller 35, which can reduce the friction between the first movable arm 31 and the second movable arm 32, making the rotation process of the first movable arm 31 easier, smoother and more labor-saving.
[0049] In some embodiments, the roller 35 is detachably connected to the first locking portion 33 . The roller 35 is easily worn during the rolling connection with the second movable arm 32 . By replacing the roller 35 alone, the service life of other structural parts of the hot press 100 can be extended.
[0050] In some embodiments, a contact surface 341 is formed on one side surface of the second clamping portion 34. When the first current is disconnected, the roller 35 contacts and rolls to connect the contact surface 341, and the contact surface 341 is a concave curved surface. The second clamping portion 34 may also have a limiting surface 342, which may be connected to the contact surface 341, and when the electromagnet 50 is supplied with the first current, the limiting surface 342 contacts the clamping surface 313. The first clamping portion 33 protrudes relative to the first movable arm 31, and the roller 35 protrudes relative to the first clamping portion 33. By setting the contact surface 341 as a concave curved surface, the roller 35 can be better accommodated and fit the shape of the roller 35, which is conducive to making the arrangement between the first movable arm 31 and the second movable arm 32 more compact.
[0051] Between the first position and the second position, the first movable arm 31 can also have a third position and a fourth position relative to the support arm 21. When the first movable arm 31 is at the third position relative to the support arm 21, the roller 35 can roll and connect the contact surface 341 and be located between the first clamping portion 33 and the contact surface 341. When the first movable arm 31 is at the fourth position relative to the support arm 21, the roller 35 can abut between the vertex formed by the connection between the contact surface 341 and the limiting surface 342 and the first clamping portion 33. For example, during the pressing process of the hot press 100, due to the action of external force, the first movable arm 31 will move from the first position to the third position, and then move from the third position to the fourth position, until the first movable arm 31 is at the second position, then the pressing process is considered to be over. During the lifting process, after the electromagnet 50 is powered off, the gas rod 40 will push the first movable arm 31 from the second position to the fourth position, and then move from the fourth position to the third position, until it returns to the initial position, that is, the first position, then the lifting process is considered to be over.
[0052] Please refer again Figure 1 and Figure 2 As shown, in some embodiments, the hot press 100 may further include a shell 13, which may be installed on the outer surface of the support arm 21 to shield and cover the surface of the support arm 21 to prevent external dust or liquid from accumulating in areas such as the connection between the first movable arm 31 and the support arm 21 or between the first movable arm 31 and the second movable arm 32, thereby affecting the service life of the internal structural parts of the hot press 100.
[0053] In some embodiments, the heat press 100 further includes a controller ( Figure 1 , Figure 2 , Figure 3 and Figure 6 The controller is the control center of the heat press 100, and uses various interfaces and lines to connect various parts of the entire heat press 100. It can receive and process information transmitted by various structural parts in the heat press 100 and output control signals to control different processes of the heat press 100.
[0054] Exemplarily, the hot press 100 may further include a position sensor ( Figure 1 , Figure 2 , Figure 3 and Figure 6 The position sensor is electrically connected to the controller, and the position sensor is fixedly connected to the support arm 21. The position sensor is used to send a detection signal to the controller when it detects that the hot pressing piece 11 is arranged parallel to the workbench 12, that is, when the first movable arm 31 is located at the second position. The detection signal is used to instruct the controller to pass the first current to the electromagnet 50. The position sensor can be an angle sensor, a distance sensor, etc., which is not limited in this application.
[0055] In other words, through the cooperation of the controller and the position sensor, when the first movable arm 31 is located at the second position, the first current can be automatically supplied to the electromagnet 50, so that the electromagnet 50 can adsorb the second end 322 of the second movable arm 32, thereby realizing the automatic locking process of the first movable arm 31, fixing the relative position of the first movable arm 31 and the support arm 21, and the hot press 100 ends the pressing process and enters the hot pressing process, thereby improving the degree of automation of the hot press 100.
[0056] When the hot press 100 completes the hot pressing process and is located at the second position again, the controller can control the disconnection of the first current, the electromagnet 50 loses power, the hot press 100 ends the hot pressing process and enters the lifting process, the second end 322 of the second movable arm 32 will be disengaged from the electromagnet 50, and the lock on the relative position between the first movable arm 31 and the support arm 21 is released. The first movable arm 31 can be driven by the gas rod 40 to rotate relative to the support arm 21 until it returns to the first position, realizing the automatic unlocking process, which is conducive to reducing the difficulty of the user to operate the hot press 100, and realizing the coherent progress of each process in the hot press 100, which is conducive to improving the working efficiency of the hot press 100. In addition, when encountering an emergency such as power failure or long hot pressing time, it is necessary to interrupt the work of the hot press 100, even if the hot pressing process has not been completed, only the first current needs to be disconnected, and the hot press 100 can enter the lifting process, so that the hot pressing piece 11 automatically pops up relative to the workbench 12, which is conducive to improving the reliability and safety of using the hot press 100.
[0057] In some embodiments, when a second current in the opposite direction of the first current is passed through the electromagnet 50, the electromagnet 50 will also repel the second movable arm 32, the electromagnet 50 will be disengaged from the second end 322 of the second movable arm 32, and the second locking portion 34 will be disengaged from the locking surface 313. During the lifting process, a reverse current can also be passed through the electromagnet 50, and the second movable arm 32 can be detached from the adsorption due to the magnetic repulsion with the electromagnet 50, and by passing the second current through the electromagnet 50, the second movable arm 32 will also be subjected to the reverse magnetic force of the electromagnet 50, which is conducive to pushing the second movable arm 32 to rotate in the opposite direction of the first rotation direction A1, and can improve the working efficiency of the process of releasing the locking of the second movable arm 32 by the electromagnet 50.
[0058] In some embodiments, the heat press 100 may further include a switch ( Figure 1 , Figure 2 , Figure 3 and Figure 6 (not shown in the figure), the controller can also be electrically connected to the electromagnet 50 and the switch, and the controller is used to pass a second current to the electromagnet 50 when the switch is triggered. It can be understood that when the operation of the heat press 100 needs to be interrupted urgently, the first power supply can be disconnected to realize the automatic lifting of the hot press 11; when the heat press 100 is in a normal process, if there is sufficient power around, the second current can also be passed to speed up the work efficiency of the lifting process of the heat press 100. By setting a switch, it is convenient for the user to control and select the working mode of the heat press 100, so that the heat press 100 can be adaptively applied to more scenarios, and the flexibility of using the heat press 100 is improved.
[0059] like Figure 7 and Figure 8 As shown, Figure 7 is a structural schematic diagram of a hot pressing machine 100 provided in an embodiment of the present application in a hot pressing process, Figure 8 yes Figure 7 The heat press machine 100 shown is a schematic structural diagram with the outer shell 13 removed.
[0060] In some embodiments, the hot press 100 further includes a driving member ( Figure 7 and Figure 8(not shown), the driving member can be connected to the support arm 21. After the electromagnet 50 absorbs the rotating assembly 30, the driving member is used to drive the support arm 21 to move relative to the base 22 in its height direction to drive the hot pressing member to move in the direction close to the workbench. It can be understood that since the support arm 21 is connected to the first movable arm 31, after the pressing process is completed, after the electromagnet 50 absorbs the rotating assembly 30, that is, when the first movable arm 31 is in the second position, there is generally a gap between the hot pressing member 11 and the workbench 12 to accommodate the substrate. By setting the driving member to drive the support arm 21 to move relative to the base 22, the hot pressing member 11 can be moved closer to the workbench 12 at the beginning of the hot pressing process, so that the contact between the hot pressing member 11 and the substrate can be closer, and the hot pressing effect is better. In this process, the first current is continuously passed to the electromagnet 50 so that the first movable arm 31 is kept in the second position relative to the support arm 21 to ensure the flatness of the hot pressing product.
[0061] like Fig. 9 As shown, Fig. 9 1 is a schematic diagram of the structure of another heat press 100 provided in an embodiment of the present application. Specifically, when the heat press 100 is in the process of heat pressing and the power supply to the heat press 100 is interrupted, the driving member will not be able to continue to drive the change of the position of the support arm 21 relative to the base 22, and the support arm 21 will remain in the position during the heat pressing process, and the electromagnet 50 can lose power, and the electromagnet 50 is disengaged from the second movable arm 32 to unlock the second movable arm 32 and the first movable arm 31, and the first movable arm 31 can rotate relative to the support arm 21, and the heat press 100 automatically enters the lifting process, and the first movable arm 31 can return to the first position, avoiding the interruption of the heat pressing process, such as power failure, the heat pressing part 11 stays on the workbench 12, is difficult to open, and causes the heat pressing time to be too long and damage the substrate.
