Description

Technical Field

[0001] The utility model relates to the field of battery baking equipment, in particular to a non-return mechanism and a baking device. Background Art

[0002] With the continuous development of the lithium battery industry, how to increase the energy density per unit volume of the battery has become a technical threshold that needs to be continuously broken through. In this context, the battery needs to be baked at high temperature in the bare cell state to remove moisture. The water content of lithium batteries has a great influence on the quality of the battery, and vacuum drying before liquid injection is an extremely critical link in controlling the water content of the battery. The battery cell in the vacuum oven is placed in a heating fixture for baking. The contacts of the heating fixture are in contact with the contacts in the oven for power and communication. The contacts of the heating fixture have springs, and the compression between the contacts of the heating fixture and the contacts of the vacuum oven in a high-temperature dry environment is very important. If the compression is too small, the contacts are prone to ignition, and if the compression is too large, it will affect the service life of the contacts.

[0003] In the prior art, the heating clamp is placed in a vacuum oven and relies on the vacuum oven to achieve positioning. Due to manufacturing and assembly errors, as well as the repulsive force between contacts, the relative position of the heating clamp and the vacuum oven is unstable, and the undesirable situation of excessive contact compression between the contacts of the heating clamp and the contacts of the vacuum oven is prone to occur. Utility Model Content

[0004] The purpose of the utility model is to provide a non-return mechanism and a baking device, which can improve the stability of the relative position of the heating clamp and the vacuum oven, more accurately position the heating clamp, so that the compression amount of the contact between the contact of the heating clamp and the contact of the vacuum oven is within a reasonable range, reduce the failure rate, and reduce the operating cost.

[0005] The embodiment of the utility model is achieved as follows:

[0006] In a first aspect, the utility model provides a non-return mechanism for use with a first component and a second component that are slidably connected, comprising:

[0007] A guide member, a check member and an elastic member, wherein the guide member is used to be connected to the second member; the check member and the guide member are slidably matched; the elastic member is connected to the guide member and the check member at the same time, and is used to make the check member have a tendency to contact the first member and drive the first member to approach the second member.

[0008] In an optional embodiment, the return stopper is provided with an abutment slope, and the abutment slope is used to contact the first component and push the first component to approach the second component.

[0009] Based on the above scheme, by setting the abutting inclined surface, the abutting inclined surface can abut against the first component under the action of the elastic member, thereby driving the first component to approach the second component. That is to say, in the initial state, the position of the check member can be controlled by the telescopic device, so that the check member overcomes the elastic force of the elastic member and retracts, the top of the check member leaves the position blocking the first component, and the first component can smoothly slide into the second component. When the first component slides into the position beyond the check member, the telescopic device is released, and under the elastic force of the elastic member, the check member slides relative to the guide member, the abutting inclined surface abuts against the first component, and can drive the first component to slide further into the second component, so that the first component and the second component are in reliable contact.

[0010] In an optional embodiment, a slider is slidably mounted on the guide member, the non-return member is connected to the slider, and the slider can drive the non-return member to slide back and forth relative to the guide member.

[0011] Based on the above scheme, the slider cooperates with the guide member, has low friction, flexible sliding, and stable and reliable sliding. When the slider slides, it can drive the check member to move, and the check member slides smoothly and reliably. In addition, the slider and the check member are processed separately, and the processing difficulty of each is low, which reduces the processing cost and improves the processing quality.

[0012] In an optional embodiment, a first limit member is installed on the guide member, and the first limit member is used to abut against the slider to prevent the slider from being separated from the guide member when sliding relative to the guide member along the first direction.

[0013] Based on the above scheme, in the process of the slider driving the check member to slide relative to the guide member, the slider can abut against the first limit member, and the first limit member can limit the sliding limit position of the slider in the first direction, thereby limiting the sliding limit position of the check member in the first direction, thereby preventing the check member from sliding off the guide member along with the slider, thereby reducing the failure rate.

[0014] In an optional embodiment, a second limit member is installed on the guide member, and the second limit member is used to abut against the slider to prevent the slider from disengaging from the guide member when the slider slides relative to the guide member in a second direction opposite to the first direction.

[0015] Based on the above scheme, through the cooperation of the first limit member and the second limit member, the sliding limit position of the slider in the first direction and the second direction can be limited, thereby preventing the slider from sliding off the guide member in the first direction and the second direction, improving the reliability of the slider during the sliding process relative to the guide member, and the cooperation between the check member and the guide member is more reliable.

[0016] In an optional embodiment, the non-return mechanism also includes a base plate, a first mounting plate and a fixed plate, the guide member and the first mounting plate are both fixedly connected to the base plate, the fixed plate is fixedly connected to the first mounting plate, one end of the elastic member is hooked to the fixed plate, and the other end is connected to the non-return member.

[0017] Based on the above scheme, by setting the base plate, the stability and strength of the overall structure can be improved, and the base plate is used to facilitate the matching of the entire non-return mechanism with the second component. The first mounting plate and the fixing plate are matched to facilitate fixing one end of the elastic member, and one end of the elastic member is hooked with the fixing plate. The connection method between the elastic member and the fixing plate is simple, and the assembly is convenient and efficient. At the same time, the elastic member and the fixing plate are easy to disassemble, which is conducive to maintenance or replacement.

[0018] In an optional embodiment, the non-return mechanism further includes a second mounting plate, the second mounting plate is fixedly connected to the non-return member, and one end of the elastic member away from the fixed plate is hooked to the second mounting plate.

[0019] Based on the above solution, one end of the elastic member is hooked with the second mounting plate, the elastic member and the second mounting plate are connected in a simple manner, the assembly is convenient, and the assembly efficiency is high. At the same time, the elastic member and the second mounting plate are easy to disassemble, which is conducive to maintenance or replacement.

[0020] In an optional embodiment, two elastic members are provided, the two elastic members are arranged in parallel and are respectively provided on two opposite sides of the fixing plate, and the two elastic members are both connected to the non-return member.

[0021] Based on the above scheme, two elastic members are symmetrically arranged on both sides of the fixed plate. The two elastic members provide elastic force at the same time to balance the force on the check member. The elastic force on the check member is consistent with the sliding direction of the check member and the guide member. The check member slides more smoothly, and the external force applied by the check member on the first component is more stable, thereby improving the accuracy and stability of the position of the first component relative to the second component, which is beneficial for the compression amount between the contact of the first component and the contact of the second component to always remain within an appropriate range.

[0022] In an optional embodiment, the check mechanism also includes a check shaft and a cam follower, the check shaft is mounted on the check member, the cam follower is rotatably mounted on the check shaft, and the cam follower is used to connect to the telescopic mechanism to overcome the elastic force of the elastic member through the telescopic mechanism and drive the guide member away from the first member.

[0025] In the second aspect, the utility model also provides a baking device, comprising a first component, a second component and the above-mentioned non-return mechanism, wherein the first component is configured as a clamp, and the clamp is provided with a first contact; the second component is configured as an oven, and the oven is provided with a second contact, and the clamp is slidably matched with the oven; the guide member is used to abut against the clamp so that the first contact has a movement tendency close to the second contact.

[0026] The beneficial effects of the embodiments of the utility model are:

[0027] In summary, the non-return mechanism provided in this embodiment, when used in conjunction with the first component and the second component, can prevent the first component from retreating relative to the second component, and improve the stability of the cooperation between the first component and the second component, wherein the first component can be a fixture, and the second component can be an oven.

The guide member of the non-return mechanism can be fixed on the oven, and when the fixture slides into the oven in a horizontal manner, the first contact on the fixture contacts the second contact in the oven. Since the first contact has elastic force, the fixture has a tendency to move outward away from the oven, that is, the first contact and the second contact have a tendency to separate. At this time, under the action of the non-return mechanism, the non-return member of the non-return mechanism abuts against the fixture under the elastic force of the elastic member, and can drive the fixture to slide into the oven, so that the first contact is close to the second contact, thereby fixing the position of the fixture, making the compression between the first contact and the second contact on the fixture moderate, and on the premise of ensuring the safety of power-on communication, extending the service life of the first contact and the second contact, and reducing the operating cost.

DETAILED DESCRIPTION

[0037] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0038] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0040] In the description of the present utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, or the orientation or position relationship in which the utility model product is usually placed when in use, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0041] In addition, the terms "horizontal", "vertical" and the like do not mean that the components are required to be absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0042] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] In the prior art, the heating clamp 007 is placed in the vacuum oven 008 and relies on the vacuum oven 008 to achieve positioning. Due to errors in manufacturing and assembly, as well as the repulsive force between contacts, the relative position of the heating clamp 007 and the vacuum oven 008 is unstable, and the undesirable situation of excessive compression between the contacts of the heating clamp 007 and the contacts of the vacuum oven 008 is prone to occur.

[0044] In view of this, the designer provides a check mechanism for use with the slidably connected clamp 007 and oven 008, which can improve the accuracy of the position of the clamp 007 relative to the oven 008, thereby reasonably controlling the compression amount of the contact between the first contact of the clamp 007 and the second contact of the oven 008, which not only meets the normal power-on and communication requirements, but also can extend the service life and reduce the cost of use.

[0045] It should be understood that the non-return mechanism can also be used in conjunction with other slidably connected first and second components, that is, the first component is not limited to a clamp, and the second component is not limited to an oven. In this way, the non-return mechanism can adapt to the use requirements of different scenarios and has a wide range of uses. In this embodiment, the non-return mechanism is used in conjunction with a clamp and an oven as an example for explanation.

[0046] Please combine Figure 1-Figure 5 In this embodiment, the non-return mechanism includes a guide member 100, a non-return member 200 and an elastic member 300. The guide member 100 is used to connect with the oven 008; the non-return member 200 and the guide member 100 are slidably matched; the elastic member 300 is connected to the guide member 100 and the non-return member 200 at the same time, and is used to make the non-return member 200 have a tendency to contact with the clamp 007 and drive the clamp 007 to approach the oven 008, so that the first contact on the clamp 007 maintains contact with the second contact on the oven 008.

[0047] Based on the above, the working principle of the non-return mechanism provided in this embodiment is as follows:

[0048] Please combine Figure 6 , it is assumed that the clamp 007 and the oven 008 are in a horizontal matching manner, that is, an operation port is provided on the side of the oven 008, and the clamp 007 can slide into or out of the oven 008 from the operation port. Correspondingly, a first contact is arranged on the right side of the clamp 007, and a second contact is arranged on the right inner wall of the oven 008. When the clamp 007 slides into the oven 008 from left to right, the first contact can contact the second contact to realize functions such as power supply and communication. The guide member 100 of the non-return mechanism can be fixed on the oven 008. When the clamp 007 slides into the oven 008 in a horizontal manner, the first contact on the clamp 007 contacts the second contact in the oven 008. Since the first contact has elastic force, the clamp 007 has a tendency to move outward from the oven 008, that is, the first contact and the second contact have a tendency to separate. At this time, under the action of the non-return mechanism, the non-return member 200 of the non-return mechanism abuts against the clamp 007 under the elastic force of the elastic member 300, and can drive the clamp 007 to slide into the oven 008, so that the first contact is close to the second contact. Since the elastic member 300 can continuously provide elastic force, when the elastic force of the first contact and the elastic force of the elastic member 300 are reasonably set, the clamp 007 can be prevented from retreating, thereby fixing the position of the clamp 007 in the oven 008, making the contact compression amount between the first contact and the second contact on the clamp 007 moderate, and on the premise of ensuring the safety of power-on communication, extending the service life of the first contact and the second contact and reducing the operating cost.

[0049] It should be noted that the non-return mechanism can be applicable to other assembly methods of the clamp 007 and the oven 008. For example, the non-return mechanism can also be applicable to the form in which the first contact and the second contact are in vertical contact, etc. The non-return mechanism can make the first contact on the clamp 007 tend to approach the second contact on the oven 008, and the position of the clamp 007 can be locked by the elastic member 300.

[0050] The following embodiments illustrate the details of the non-return mechanism provided in the present application by way of examples.

[0051] Please combine Figure 1-Figure 4 In this embodiment, the check mechanism includes a guide member 100, a check member 200, two elastic members 300, a slider 400, a first limit member 500, a second limit member 600, a base plate 700, a first mounting plate 800, a fixing plate 900, a second mounting plate 001, a check shaft 002, two cam followers 003, two retaining springs 004, a reinforcing rib 005 and a micro switch module 006.

[0052] The guide member 100 and the first mounting plate 800 are both fixed on the base plate 700, and the reinforcing rib 005 is connected to the first mounting plate 800 and the base plate 700 at the same time, so as to improve the stability of the first mounting plate 800. The check member 200 is installed on the slider 400, and the slider 400 is slidably matched with the guide member 100. The first limiter 500 and the second limiter 600 are both connected to the base plate 700 and arranged at intervals, and the slider 400 can slide relative to the guide member 100 between the first limiter 500 and the second limiter 600, and the first limiter 500 and the second limiter 600 cooperate to limit the sliding range of the slider 400, so as to prevent the slider 400 from sliding off the guide member 100. The fixing plate 900 is fixed on the first mounting plate 800, and one end of the elastic member 300 is hooked with the fixing plate 900. The second mounting plate 001 is connected to the check member 200, and the other end of the elastic member 300 is hooked to the second mounting plate 001. When the check member 200 abuts against the clamp 007, the elastic member 300 is in a stretched state, and has a movement tendency to make the check member 200 drive the clamp 007 to slide into the oven 008. The two elastic members 300 are respectively arranged on the opposite sides of the fixing plate 900, which can provide a stable elastic force to make the check member 200 more balanced. The check shaft 002 passes through the check member 200, and the two retaining springs 004 are both clamped outside the check shaft 002. The two retaining springs 004 clamp the check member 200 to limit the check shaft 002 from sliding relative to the check member 200. The two cam followers 003 can be rotatably mounted outside the check shaft 002 and are respectively located on both sides of the check member 200. The retractor is connected to the cam follower 003, and the elastic force of the elastic member 300 can be overcome to drive the check member 200 to slide in the opposite direction. The micro switch module 006 is installed on the slider 400 and the base plate 700. The micro switch module 006 can detect whether the check member 200 is in a normal working state, and can be adjusted in time when the check member 200 is in a stuck state.

[0053] In this embodiment, the base of the check mechanism can be fixed on the side of the oven 008, the guide member 100 extends vertically, the elastic member 300 extends vertically, and the elastic member 300 can drive the slider 400 to slide upward relative to the guide member 100, thereby driving the check member 200 to slide upward. When the check member 200 slides upward for a set distance, the micro switch module 006 is triggered, and the surface check member 200 is in a normal operating state. When the position of the check member 200 needs to be adjusted to facilitate the clamp 007 to enter and exit the oven 008, the telescope is used to engage with the two cam followers 003, and the telescope is contracted to drive the check member 200 to descend and leave the side of the passage for the clamp 007 to enter and exit the oven 008, so that there will be no interference with the clamp 007, which is conducive to the assembly of the clamp 007 and the oven 008.

[0054] In this embodiment, optionally, the substrate 700 is a rectangular plate, the guide member 100 can be fixed to a plate surface of the substrate 700 by fasteners such as screws, the guide member 100 can be set as a guide rail, and the guide rail has sliding grooves 101 on opposite sides. The slider 400 is slidably matched with the guide rail, and the slider 400 is snap-fitted with the sliding groove 101 to prevent the slider 400 from being separated from the guide rail when it moves away from the substrate 700 in a direction perpendicular to the substrate 700.

[0055] Please combine Figure 4 Further, a mounting groove 701 is provided on the other opposite plate surface of the substrate 700, the first mounting plate 800 is a rectangular plate, one side of the first mounting plate 800 is inserted into the mounting groove 701 and is arranged perpendicular to the substrate 700, and the substrate 700 and the first mounting plate 800 can be fixedly connected by fasteners such as bolts. For example, the fastener penetrates the substrate 700 from the plate surface of the substrate 700 on which the guide member 100 is installed, and then is screwed and fixed to the first mounting plate 800. The reinforcing rib 005 can be a right-angled triangular plate, the reinforcing rib 005 is clamped between the first mounting plate 800 and the substrate 700, and is located below the first mounting plate 800, and the reinforcing rib 005 can be fixedly connected to the substrate 700 and the first mounting plate 800 by bolts. By providing the reinforcing rib 005, the connection strength between the first mounting plate 800 and the substrate 700 can be improved, the first mounting plate 800 can withstand greater external forces, and is safe and reliable to use.

[0056] Optionally, the fixing plate 900 is configured as a bent plate, and the fixing plate 900 can be fixed to the top surface of the first mounting plate 800 by fasteners such as bolts, and the opposite sides of the fixing plate 900 extend out of the corresponding sides of the first mounting plate 800, respectively, and the position where the fixing plate 900 extends out of the first mounting plate 800 is provided with a first hanging hole 901, that is, the fixing plate 900 is provided with two first hanging holes 901, and the two first hanging holes 901 are respectively located on both sides of the first mounting plate 800 and protrude from the first mounting plate 800, and one end of the two elastic members 300 is respectively hooked with the two first hanging holes 901, and since the first hanging buckle protrudes from the first mounting plate 800, the first mounting plate 800 will not interfere with the elastic member 300. The elastic member 300 is hooked with the first hanging hole 901, and the assembly method is simple, easy to disassemble and assemble, and efficient.

[0057] It should be understood that the fixing plate 900 can be formed by bending a metal plate. The processing method of the fixing plate 900 is simple, and the overall structural strength is high. It is not easy to deform during use and has a long service life.

[0058] Please combine Figure 4In this embodiment, the second mounting plate 001 is optionally a bent plate, and the second mounting plate 001 is roughly U-shaped. The second mounting plate 001 is fixed to the backstop 200 by fasteners such as bolts, and the backstop 200 is clamped in a groove formed by the second mounting plate 001. Specifically, the second mounting plate 001 includes a first plate body 011, a second plate body 012, and a third plate body 013 connected in sequence. The first plate body 011 and the third plate body 013 are relatively parallel. The second plate body 012 is attached to the side of the backstop 200 away from the slider 400, and the bolts fix the second plate body 012 to the backstop 200. The first plate 011 and the third plate 013 are located on opposite sides of the check member 200. The first plate 011 and the third plate 013 are both provided with second hanging holes 014. The ends of the two elastic members 300 away from the fixing plate 900 are respectively hooked with the two second hanging holes 014. The installation method of the elastic members 300 and the second mounting plate 001 is simple and the assembly efficiency is high. The two elastic members 300 are symmetrically arranged and provide elastic force at the same time. The elastic force is stable, and the direction of the elastic force is basically consistent with the sliding direction of the slider 400. The slider 400 slides smoothly, and the stop member 200 has a good limiting effect.

[0059] It should be understood that the second mounting plate 001 can be made of bent metal plates, which has high structural strength and long service life.

[0060] In this embodiment, optionally, the first limiter 500 may be a limiter block, the first limiter 500 may be fixedly connected to the guide member 100 by means of bolts or other structural members, the second limiter 600 may be a limiter sheet metal, the second limiter 600 may be fixedly connected to the guide member 100 by means of bolts or other structural members, and the first limiter 500 is located above the second limiter 600. The slider 400 is located between the first limiter 500 and the second limiter 600, and when the slider 400 slides relative to the guide member 100 in the first direction, that is, when the slider 400 slides upward to the first preset position, the slider 400 can abut against the first limiter 500, and the first limiter 500 limits the slider 400 to the extreme position of sliding upward, preventing the slider 400 from sliding off the guide member 100 in the first direction. Similarly, when the slider 400 slides relative to the guide member 100 in the second direction, that is, when the slider 400 slides downward to the second preset position, the slider 400 can abut against the second stopper 600, and the second stopper 600 limits the extreme position of the slider 400 sliding downward, preventing the slider 400 from sliding off the guide member 100 in the second direction. The first direction and the second direction are both vertical directions and opposite to each other. In this way, the slider 400 is limited by the first stopper 500 and the second stopper 600, which determines the sliding range of the slider 400, and also prevents the slider 400 from sliding off the guide member 100, thereby reducing the failure rate.

[0061] Please combine Figure 5 and Figure 6 In this embodiment, the check member 200 is optionally configured as a check block, and one plate surface of the check block is in contact with the slider 400, and the two can be fixedly connected by bolts and other structural members. A contact slope 210 is provided on one side of the plate surface of the check block connected to the slider 400, and the contact slope 210 has an angle α with the vertical plane, and the value range of the angle α can be 15-21°, for example, the angle α can be 15°, 18° or 21°, etc. Further, the contact slope 210 is provided with anti-skid patterns 211, for example, the anti-skid patterns 211 of this embodiment are configured as a plurality of grooves arranged in an alternating manner. In actual operation, the stopper 200 is arranged vertically, and the contact slope 210 faces upward. Driven by the elastic member 300, the stopper 200 has a tendency to move upward, that is, the contact slope 210 has a tendency to move upward. When the contact slope 210 moves upward and contacts the clamp 007 on the right side, the contact slope 210 can drive the clamp 007 to move rightward, thereby controlling the position of the clamp 007. Since the angle α of the contact slope 210 is between 15-21°, the groove of the anti-slip pattern 211 on the contact slope 210 can cooperate with the guide rail of the clamp 007, so that the contact slope 210 has a self-locking function, and the stopper 200 will not automatically move downward and leave the clamp 007, thereby improving the stability of the position of the clamp 007.

[0062] It should be understood that due to the design of the abutment slope 210 on the check piece 200, when it is necessary to adjust the position of the clamp 007 relative to the oven 008, the telescope can be used to engage with the two cam followers 003. The contraction of the telescope drives the check piece 200 to move downward, so that the abutment slope 210 leaves the position of abutting against the clamp 007. The freedom of the clamp 007 to move to the left is not restricted by the check piece 200, and there will be no interference between the clamp 007 and the check piece 200, which is conducive to the adjustment of the position of the clamp 007.

[0063] It should be understood that the telescopic device can be a cylinder, a hydraulic cylinder, etc., which can overcome the elastic force of the elastic member 300 and drive the non-return member 200 to move.

[0064] It should be noted that the elastic member 300 may be a tension spring, which has a simple structure, is easy to obtain, has a low cost, can provide a stable and lasting elastic force, and has a long service life.

[0065] The non-return mechanism provided in this embodiment can drive the non-return member 200 to move upward through the elastic force provided by the elastic member 300, and the abutting inclined surface 210 on the non-return member 200 can abut against the left side of the clamp 007. The non-return member 200 moves upward and drives the clamp 007 to move rightward, so that the first contact point on the clamp 007 is in close contact with the second contact point on the oven 008, ensuring that the compression amount of the contact between the first contact point and the second contact point is within the set range, ensuring the stability and reliability of the operation. Since the angle of the abutting inclined surface 210 is between 15-21°, the abutting inclined surface 210 has a self-locking function after contacting the clamp 007, the non-return member 200 is not easy to automatically retreat, and the position of the clamp 007 is stable and reliable.

[0066] Please combine Figure 6 This embodiment also provides a baking device, including a clamp, an oven, and the non-return mechanism of the above embodiment. The clamp is provided with a first contact, the oven is provided with a second contact, the clamp is placed in the oven and slidably cooperates with the oven. The guide is connected to the oven, and the non-return member is used to abut against the clamp so that the first contact has a movement tendency close to the second contact, so that the first contact and the second contact can contact as required, so that the compression amount of the contact between the first contact and the second contact is within a reasonable range, thereby reducing the failure rate and reducing the operating cost.

[0067] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
