Technical Field
[0001] This utility model relates to the field of vacuum sintering technology, and in particular to a transfer device and system. Background Technology
[0002] Metal Powder Injection Molding Technology (MIM) is a novel near-net-shape forming technology in powder metallurgy, formed by introducing modern plastic injection molding technology into the field of powder metallurgy. The MIM process flow is as follows: 1. Mixing metal powder and binder; 2. Molding; 3. Debinding; 4. Sintering; 5. Post-processing; 6. Finished product. MIM technology features high output and easy molding control. However, the high output results in the most complex step in the process being the loading and unloading of parts to be transferred (parts to be transferred include graphite plates and the products they support, including products to be sintered or sintered products; some products are supported by ceramic plates, and the ceramic plates and the products they support are placed on graphite plates). Manual loading and unloading require significant physical effort and precise handling to prevent shaking or swaying, which could cause the parts to tip over and become unusable after sintering. The unloading process is equally complex. In order to improve the utilization rate of the furnace, the furnace body is generally not allowed to cool down completely before unloading. The high-temperature sintering of the furnace body keeps the parts to be transferred in a high-temperature state. Manual unloading will cause unnecessary burns.
[0003] When using transfer devices for loading and unloading, existing transfer devices typically possess vertical lifting and rolling transmission (such as roller frames) or belt transmission functions. By replacing some manual operations with mechanical transmission, they can reduce manpower and improve transfer efficiency. For example, lifting devices can be used to adjust the height to connect different workstations, and rolling or belt transmission can be used to achieve horizontal movement of the parts to be transferred, reducing the physical exertion of manual handling to some extent. However, existing technologies still pose safety hazards in high-temperature environments. In the unloading stage, the furnace body reaches extremely high temperatures (above 100 degrees Celsius) after high-temperature sintering, and the parts to be transferred are in a high-temperature state. Existing transfer devices only complete material transfer through lifting and transmission functions, resulting in the risk of high-temperature radiation or direct contact burns when approaching the furnace body for docking. For example, when using traditional roller frames or belts to transport high-temperature materials, operators need to adjust the material position at close range, which can easily lead to safety accidents due to furnace heat dissipation or accidental slippage of the parts to be transferred.
[0004] Therefore, how to provide a transfer device and system that can smoothly and safely transfer the parts to be transferred is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0005] The purpose of this utility model is to address the defects and deficiencies in the existing technology by providing a transfer device and system that can smoothly and safely transfer the parts to be transferred, avoiding the product tipping over during the transfer process and causing the sintered parts to be transferred to be scrapped; and avoiding the material being too close to the furnace body during discharge, so as to prevent burns when transferring parts that have just come out of the furnace and are in a high-temperature state.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] This utility model provides a transfer device, including a frame, a vertical displacement adjustment device mounted on the frame, and a horizontal displacement adjustment device fixed on the vertical displacement adjustment device.

The displacement detection component is used to detect whether the part to be transferred has reached a preset transfer position. The displacement detection component is electrically connected to the control device. Based on the detection result of the displacement detection component, the control device controls the horizontal displacement adjustment device to move up and down in the vertical direction or controls the horizontal drive mechanism to push the moving support plate away from or towards the fixed support plate in the horizontal direction.
[0013] In one embodiment, the fixed support plate and the movable support plate are provided with spaced auxiliary moving parts, which are used to reduce the friction between the part to be transferred and the fixed support plate and the movable support plate.

The stopping electromagnets are electrically connected to the control device.
[0015] In one embodiment, the limiting component further includes a width limiting component, which includes a width limiting bar and a displacement adjusting device. The width limiting bar is disposed on both sides of the width direction of the first support frame, and the displacement adjusting device is connected to the first support frame and the width limiting bar, and is used to adjust the relative position between the width limiting bar and the first support frame to prevent the transfer parts of different widths from leaving the horizontal platform.
[0016] In one embodiment, the horizontal displacement adjustment device further includes a second support frame located below the first support frame. The second support frame and the first support frame are connected by a table leveling device, which is used to adjust the horizontal state of the first support frame.
[0017] The table leveling device includes a ball screw, a movable base, and two fixed bases fixed to the second support frame. The two ends of the ball screw are respectively connected to the two fixed bases. The movable base is sleeved on the part of the ball screw located between the two fixed bases.

[0018] In one embodiment, the horizontal displacement adjustment device further includes an anti-offset positioning component. The anti-offset positioning component includes a guide member disposed on the first support frame and a guide post disposed on the second support frame. The guide member is provided with a guide channel for passing through and restricting the movement direction of the guide post. The guide post passes through the guide channel and moves up and down in the vertical direction within the guide channel.

The limiting stop and the active adsorption component are fixed at intervals on the outer wall of the bushing. The passive adsorption component is fixed on the rotating shaft. The active adsorption component and the passive adsorption component are magnetically attracted to each other. The rotating shaft can drive the passive adsorption component to rotate within the range limited by the limiting stop and the active adsorption component, so that the auxiliary pusher rotates to the pushing state or returns to its original position. The two ends of the return spring are respectively fixed on the end faces of the passive adsorption component and the active adsorption component away from the bushing. The return spring is used to assist the passive adsorption component in returning to its original position.
[0021] In one embodiment, the vertical displacement adjustment device includes a first driving device, a transmission component axially connected to the first driving device, and a transmission component connected to the transmission component;
[0022] The transmission assembly includes a transmission chain, an inner connecting plate connected to the transmission chain, and an outer connecting plate fixed to the inner connecting plate. The horizontal displacement adjustment device is fixed to the outer connecting plate.
[0023] This utility model also provides a transfer system, including a material cart, a sintering furnace, and the aforementioned transfer device, wherein the transfer device is used to transfer the parts to be transferred between the material cart and the sintering furnace.
[0024] The present invention achieves the following technical advantages over the prior art:
[0025] This invention, through the inclusion of vertical and horizontal displacement adjustment devices, enables automated displacement adjustment of the parts to be transferred in both vertical and horizontal directions, reducing manual operation and labor intensity. It also improves the efficiency of loading, unloading, and transferring parts, mitigating problems caused by complex and time-consuming manual operations. A fixed support plate and a sliding movable support plate are installed on the first support frame of the horizontal platform. Driving the movable support plate along the first support frame allows for stable transfer of the parts from the material cart to the fixed support plate, then to the movable support plate, and finally into the sintering furnace, or vice versa. This prevents high-temperature burns to the furnace body during transfer. Limiting components prevent the parts from detaching from the transfer device due to shaking or wobbling caused by manual operation during the transfer process. Attached Figure Description

[0045] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0046] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0047] by Figure 8 For reference, the first direction X is the horizontal direction between the fixed support plate 312 and the movable support plate 313; the second direction Y is the horizontal direction between the outer connecting plate 260 and the first beam frame 3113; and the third direction Z is the vertical direction between the second support frame 320 and the first support frame 311. The first direction X, the second direction Y, and the third direction Z intersect each other perpendicularly.
[0048] like Figure 1-4 , Figure 8-9 As shown, this utility model provides a transfer device, including a frame 100, a vertical displacement adjustment device 200 mounted on the frame 100, and a horizontal displacement adjustment device 300 fixed on the vertical displacement adjustment device 200. The vertical displacement adjustment device 200 is used to drive the horizontal displacement adjustment device 300 to move up and down along the vertical direction (i.e., the third direction Z). The horizontal displacement adjustment device 300 includes a horizontal platform 310, which includes a first support frame 311, a fixed support plate 312, and a movable support plate 313. One end of the first support frame 311 is fixed to the fixed support plate 312, and the other end is slidably connected to the movable support plate 313. The movable support plate 313 moves away from or towards the fixed support plate 312 along the horizontal direction. The fixed support plate 312 can be aligned with the workpiece placement station on the material cart (i.e., the placement position of the workpiece to be transferred). The workpiece placement station on the material cart is multi-layered and spaced apart along the third direction Z. Each layer can place the workpiece to be transferred. The alignment position is the workpiece placement station where the workpiece to be transferred is placed. The movable support plate 313 can extend into the interior of the sintering furnace and align with the workpiece placement station inside the sintering furnace (i.e., the placement position of the workpiece to be transferred; the workpiece placement station inside the sintering furnace is multi-layered and spaced along the third direction Z; each layer can place the workpiece to be transferred, and the alignment position is the workpiece placement station where the workpiece to be transferred is placed), so as to transfer the workpiece to be transferred between the material cart and the sintering furnace; the horizontal displacement adjustment device 300 also includes a limiting component set on the horizontal platform 310, which is used to prevent the workpiece to be transferred from leaving the horizontal platform 310; it also includes a control device 400, which is electrically connected to the vertical displacement adjustment device 200. The control device 400 includes a control panel 410 and a combination control key 420 for inputting control commands, such as the vertical displacement adjustment device 200 being used to drive the horizontal displacement adjustment device 300 to move up and down in the vertical direction (i.e., the third direction Z).
[0049] Understandably, when transferring the part to be transferred from the material cart to the sintering furnace, firstly, the horizontal displacement adjusting device 300 is moved along the third direction Z by the control device 400 to be at the same height as the workpiece placement position on the material cart (when the part to be transferred is a graphite plate, due to the deformation of the graphite plate, the horizontal displacement adjusting device 300 needs to be slightly lower than the workpiece placement position on the material cart), transferring the part to be transferred from the material cart to the fixed support plate 312; then, after the part to be transferred is completely transferred to the fixed support plate 312, the horizontal displacement adjusting device 300 is moved along the third direction Z by the control device 400 to be at the same height as the workpiece placement position inside the sintering furnace (when the part to be transferred is a graphite plate, due to the deformation of the graphite plate, the horizontal displacement adjusting device 300 needs to be slightly higher than the workpiece placement position inside the sintering furnace). The height of the workstation is adjusted so that, when the workpiece to be transferred is subsequently moved into the sintering furnace, after the center of gravity of the workpiece is transferred into the sintering furnace, the horizontal displacement adjustment device 300 moves along the third direction Z to be at the same height as the workpiece placement station in the sintering furnace, thereby allowing the workpiece to be transferred to smoothly detach from the moving support plate 313; and pushes the workpiece to be transferred on the fixed support plate 312 towards the moving support plate 313 along the first direction X until the center of gravity of the workpiece to be transferred or the workpiece to be transferred is completely transferred onto the moving support plate 313; finally, it pushes the moving support plate 313 along the first direction X to move away from the fixed support plate 312 on the first support frame 311 and closer to the workpiece placement station in the sintering furnace where the workpiece to be transferred is placed, and then transfers the workpiece to be transferred on the moving support plate 313 to the workpiece placement station in the sintering furnace. During this transfer process, the limiting component set on the horizontal platform 310 is used to prevent the workpiece to be transferred from detaching from the horizontal platform 310. When transferring the workpiece to be transferred from the sintering furnace to the material cart, the process is reversed, and will not be described again here.
[0050] Reference Figures 8-9 In some specific embodiments, a horizontal drive mechanism 314 is provided on the first support frame 311. The moving end of the horizontal drive mechanism 314 is connected to the movable support plate 313, and the horizontal drive mechanism 314 is electrically connected to the control device 400. The first support frame 311 includes an outer frame 3112 and an inner frame 3111. The outer frame 3112 is a frame structure composed of a first beam frame 3113 and a second beam frame 3114. The first beam frame 3113 is parallel to the first direction X, and the second beam frame 3114 is parallel to the second direction Y. A displacement detection component 340 is provided on the first beam frame 3113. The displacement detection component 340 is used to detect whether the part to be transferred has reached the preset transfer position. The displacement detection component 340 is electrically connected to the control device 400. Based on the detection result of the displacement detection component 340, the control device 400 controls the horizontal displacement adjustment device 300 to move up and down in the vertical direction or controls the horizontal drive mechanism 314 to push the movable support plate 313 away from or towards the fixed support plate 312 in the horizontal direction.
[0051] Understandably, the horizontal drive mechanism 314 includes a slider 3144, a slide rail 3143, an electric push rod 3141, and a connector 3142. The slider 3144 is mounted on the movable support plate 313, and the slide rail 3143 is mounted on the first support frame 311. The slider 3144 is slidably connected to the slide rail 3143. The electric push rod 3141 is electrically connected to the control device 400. The fixed end of the electric push rod 3141 is fixed to the first support frame 311, and the moving end is fixed to the movable support plate 313 through the connector 3142. The movable support plate 313 is located above the inner frame 3111 and is slidably connected to the top surface of the inner frame 3111. The slide rail 3143 is arranged on the first support frame 311 along the first direction X. The slide rail 3143 provides linear motion guidance for the slider 3144. The control device 400 controls the electric push rod 3141 to extend and retract, thereby pushing the movable support plate 313 to move synchronously, so that the movable support plate 313 moves away from the fixed support plate 312 along the first direction X, so as to transport the parts to be transferred on the fixed support plate 312 into the sintering furnace through the movable support plate 313; or the movable support plate 313 moves closer to the fixed support plate 312 along the first direction X, so as to transport the parts to be transferred in the sintering furnace onto the fixed support plate 312.
[0052] The preset transfer positions include a first preset transfer position, a second preset transfer position, a third preset transfer position, and a fourth preset transfer position. The displacement detection component 340 includes a first displacement detection element 341 for detecting the first preset transfer position, a second displacement detection element 342 for detecting the second preset transfer position, a third displacement detection element 343 for detecting the third preset transfer position, and a fourth displacement detection element 344 for detecting the fourth preset transfer position. The first displacement detection element 341, the second displacement detection element 342, the third displacement detection element 343, and the fourth displacement detection element 344 are arranged at intervals along the first direction X on the first beam frame 3113.
[0053] During the transfer of the workpiece from the material cart to the sintering furnace, when the center of gravity of the workpiece shifts from the material cart to the fixed support plate 312, the position where the end of the workpiece in the direction of movement covers the second displacement detector 342 and is detected by the second displacement detector 342 is considered to be the workpiece in the second preset transfer position. At this time, the control device 400 controls the horizontal displacement adjustment device 300 to move along the vertical direction (third direction Z) until it is at the same height as the workpiece placement station in the sintering furnace (when the workpiece to be transferred is a easily deformable workpiece such as a graphite plate, the horizontal displacement adjustment device 300 needs to be slightly higher than the workpiece placement station in the sintering furnace). When the center of gravity of the workpiece shifts from the fixed support plate 312 to the moving support plate 313, the position where the end of the workpiece in the direction of movement covers the third displacement detector 343 and is detected by the third displacement detector 343 is considered to be the workpiece in the third preset transfer position. At this time, the control device 400 controls the horizontal drive mechanism 314 to push the moving support plate 313 away from the fixed support plate 312 along the first direction X. When the workpiece to be transferred is a graphite plate or other easily deformable workpiece, when the center of gravity of the workpiece to be transferred is transferred from the moving support plate 313 to the sintering furnace, the end of the workpiece to be transferred in the opposite direction of the moving direction (i.e. the opposite direction of the first direction X) is no longer covered by the fourth displacement detection element 344 and is not detected by the fourth displacement detection element 344. This position is considered as the workpiece to be transferred being in the fourth preset transfer position. At this time, height compensation is performed, and the control device 400 controls the horizontal displacement adjustment device 300 to move along the vertical direction (the third direction Z) until it is at the same height as the workpiece placement position in the sintering furnace.
[0054] During the transfer of the workpiece from the sintering furnace to the material cart, when the center of gravity of the workpiece shifts from the sintering furnace to the movable support plate 313, the position where the end of the workpiece in the direction of movement covers the third displacement detector 343 and is detected by the third displacement detector 343 is considered as the workpiece being in the third preset transfer position. At this time, the control device 400 controls the horizontal drive mechanism 314 to push the movable support plate 313 towards the fixed support plate 312 in the opposite direction of the first direction X. When the workpiece is completely transferred to the movable support plate 313, the position where the end of the workpiece in the opposite direction of movement (i.e., the opposite direction of the first direction X) no longer covers the fourth displacement detector 344 and is no longer detected by the fourth displacement detector 344 is considered as the workpiece being in the fourth preset transfer position. At this time, the control device 400 controls the horizontal displacement adjustment device 300 to move in the vertical direction (the third direction Z) until it is at the same height as the workpiece placement device on the material cart (when the workpiece to be transferred is a easily deformable workpiece such as a graphite plate, the horizontal displacement adjustment device 300 needs to be slightly higher than the workpiece on the material cart). (Workpiece placement station height); When the workpiece to be transferred is a graphite plate or other easily deformable workpiece, when the center of gravity of the workpiece to be transferred is transferred from the fixed support plate 312 to the material cart, the end of the workpiece to be transferred in the opposite direction of movement (i.e., the first direction X) no longer covers the first displacement detection element 341, and the position not detected by the first displacement detection element 341 is regarded as the workpiece to be transferred being in the first preset transfer position. At this time, height compensation is performed, and the control device 400 controls the horizontal displacement adjustment device 300 to move along the vertical direction (the third direction Z) until it is at the same height as the workpiece placement station in the material cart.
[0055] It should be noted that the positions of the first displacement detection element 341, the second displacement detection element 342, the third displacement detection element 343, and the fourth displacement detection element 344 differ depending on the size of the parts to be transferred. The specific operational settings for the control device 400 to control the horizontal displacement adjustment device 300 to move vertically up and down or to control the horizontal drive mechanism 314 to push the moving support plate 313 horizontally away from or towards the fixed support plate 312 based on the detection results of the displacement detection component 340 are not unique; as long as the control function is achieved, it is acceptable.
[0056] Reference Figure 8 In some specific embodiments, at least two auxiliary moving parts 315 are provided on the fixed support plate 312 and the movable support plate 313 at intervals. The auxiliary moving parts 315 are used to reduce the friction between the part to be transferred and the fixed support plate 312 and the movable support plate 313. The auxiliary moving parts 315 can be rollers, universal bearings, etc. When the part to be transferred is large and it is in contact with the first beam frame 3113, the top surface of the first beam frame 3113 can also be provided with auxiliary moving parts 315 at intervals.
[0057] Reference Figure 8 , Figure 9 In some specific embodiments, the limiting component includes two stopping electromagnets 330 disposed on the platform of the second beam frame 3114. The stopping electromagnets 330 are spaced apart on the platform of the second beam frame 3114, and the distance between adjacent stopping electromagnets 330 is less than the width of the component to be transferred. The stopping electromagnets 330 include a blocking state for blocking the component to be transferred from passing through and a passing state for allowing the component to be transferred to pass through. The stopping electromagnets 330 are electrically connected to the control device 400.
[0058] Understandably, during the process of transferring the workpiece from the material cart to the sintering furnace, when the horizontal displacement adjusting device 300 moves vertically (in the third direction Z) to the same height as the workpiece placement position on the material cart, the vertical displacement adjusting device 200 stops moving. The stopping electromagnet 330 on the second beam 3114 near the material cart is in a passing state, while the stopping electromagnet 330 on the second beam 3114 near the sintering furnace is in a blocking state. After the workpiece is completely transferred to the horizontal platform 310, both the stopping electromagnets 330 on the second beam 3114 near the material cart and the stopping electromagnets 330 on the second beam 3114 near the sintering furnace are in a blocking state to prevent… The workpiece to be transferred slides off the horizontal platform 310 in the first direction X; when the horizontal displacement adjustment device 300 moves along the vertical direction (the third direction Z) to the same height as the workpiece placement station inside the sintering furnace (if the workpiece to be transferred is a easily deformable workpiece such as a graphite plate, the horizontal displacement adjustment device 300 is slightly higher than the height of the workpiece placement station inside the sintering furnace), the vertical displacement adjustment device 200 stops moving, the stopping electromagnet 330 on the second beam 3114 near the material cart is in a blocking state, and the stopping electromagnet 330 on the second beam 3114 near the sintering furnace is in a passing state, facilitating the smooth transfer of the workpiece to be transferred from the horizontal platform 310 to the sintering furnace (the workpiece placement station inside the sintering furnace). During the process of transferring the workpiece to be transferred from the sintering furnace to the material cart, the state of the stopping electromagnet 330 is the reverse of the above process, which will not be described again here.
[0059] Reference Figures 8 to 10 In some specific embodiments, the limiting component further includes a width limiting component, which includes a width limiting bar 350 and a displacement adjusting device. The width limiting bar 350 is disposed on both sides of the width direction of the first support frame 311. The displacement adjusting device connects the first support frame 311 and the width limiting bar 350 and is used to adjust the relative position between the width limiting bar 350 and the first support frame 311 to prevent parts of different widths from leaving the horizontal platform 310.
[0060] Understandably, the width-limiting baffle 350 is placed on the extension bracket 316 of the first support frame 311. The displacement adjustment device can be a bolt and a nut. The bolt passes through the adjustment elongated hole 351 opened on the width-limiting baffle 350 and the screw hole 352 on the extension bracket 316 in sequence, and is connected to the nut to fix the width-limiting baffle 350 on the extension bracket 316 of the first support frame 311. The length of the adjustment elongated hole 351 is the adjustment range of the width-limiting baffle 350 relative to the first support frame 311.
[0061] When the displacement adjustment device can achieve automatic adjustment, the displacement adjustment device (which can be an electric push rod, an electric slide, a stepper motor + lead screw, etc.) is electrically connected to the control device 400. The fixed end of the displacement adjustment device is connected to the first support frame 311, and the moving end of the displacement adjustment device is connected to the width limiting bar 350. When it is necessary to adjust the relative position between the width limiting bar 350 and the first support frame 311, the control device 400 controls the movement of the moving end of the displacement adjustment device to push the width limiting bar 350 to move synchronously, so as to adjust the relative position between the width limiting bar 350 and the first support frame 311 and prevent the parts to be transferred of different widths from falling off the horizontal platform 310.
[0062] In extreme cases where the factory floor is uneven, the entire transfer device (including the horizontal platform 310 for transporting the parts to be transferred) may tilt. When the parts to be transferred are transported via the horizontal platform 310, they may tip over, causing the sintered parts to become unusable. (Refer to...) Figures 8-10 In some specific embodiments, the horizontal displacement adjustment device 300 further includes a second support frame 320, which is located below the first support frame 311. The second support frame 320 and the first support frame 311 are connected by a table leveling device 360, which is used to adjust the horizontal state of the first support frame 311.
[0063] The table leveling device 360 includes a ball screw 362, a movable base, and two fixed bases 361 fixed on the second support frame 320. The two ends of the ball screw 362 are respectively connected to the two fixed bases 361. The movable base is sleeved on the part of the ball screw 362 located between the two fixed bases 361. A first wedge block 363 is fixed on the movable base. A second wedge block 364 is fixedly connected to the first support frame 311. The sliding surface of the first wedge block 363 is adapted to the sliding surface of the second wedge block 364.
[0064] The input end of the ball screw 362 is fixed with a second drive device 365 (which can be a manually adjustable leveling handwheel or an automatically adjustable drive motor, etc.), and a locking member 366 is connected to a fixed base 361. The locking member 366 is used to limit the rotation of the ball screw 362 within the fixed base 361.
[0065] It is understandable that uneven factory floors cause the horizontal platform 310 for transporting parts to be transferred to be tilted. In this case, the first support frame 311 and the second support frame 320 are connected by four sets (usually in a rectangular distribution) of platform leveling devices 360. The slope angle of the first wedge block 363 and the second wedge block 364 can be designed to be 15° to 30° to form a self-locking structure. An electromagnetic or mechanical locking part 366 is provided on the outside of the fixed base 361 to lock the ball screw 362 after leveling to prevent rotation.
[0066] In use, the required leveling displacement is determined, and the second leveling drive device 365 drives the ball screw 362 to rotate. The moving base translates relative to the plane of the second support frame 320 along the second direction Y or the opposite direction of the second direction Y. Through the inclined plane conversion of the wedge block, the displacement in the second direction Y is converted into the third direction Z-axis height adjustment (the displacement amplification ratio is about 1:3 to 1:5). Through the coordinated action of multiple sets of table leveling devices 360, the flatness of the first support frame 311 is precisely adjusted. After the target levelness is achieved, the ball screw 362 is locked by the locking member 366. At this time, the first support frame 311 is in a horizontal state, thereby ensuring that the fixed support plate 312 and the moving support plate 313 on the first support frame 311 are in a horizontal state, preventing the parts to be transferred from tipping over when transported through the horizontal platform 310.
[0067] Reference Figures 8 to 10 In some specific embodiments, the horizontal displacement adjustment device 300 further includes an anti-offset positioning component 370. The anti-offset positioning component 370 includes a guide member 371 disposed on the first support frame 311 and a guide post 372 disposed on the second support frame 320. The guide member 371 is provided with a guide channel 373 for passing through and restricting the movement direction of the guide post 372. The guide post 372 passes through the guide channel 373 and moves up and down in the vertical direction within the guide channel 373.
[0068] Understandably, the guide post 372 and the guide channel 373 form a sliding pair, allowing only the first support frame 311 to move relative to the plane of the second support frame 320 along the third direction Z (vertical direction). The four sets of anti-offset positioning components 370 can completely constrain the translational degrees of freedom in the first direction X / second direction Y and the rotational degrees of freedom around the Z axis. When the platform leveling device 360 adjusts the levelness, the guide post 372 slides up and down synchronously within the guide channel 373. When the platform leveling device 360 adjusts the levelness of the first support frame 311, the anti-offset positioning components 370 ensure the relative positional accuracy of the two frames during the adjustment process.
[0069] In order to achieve the positional movement of the entire transfer device, refer to Figures 1-3 , Figures 11-12In some specific embodiments, the frame 100 is fixed on a movable base. The bottom of the movable base is equipped with two large and two small self-locking casters, including two large casters 502 and two small casters 501. An auxiliary pushing device 600 is fixed on the frame 100 to assist in pushing the entire transfer device. The auxiliary pushing device 600 includes a bushing 610, a rotating shaft 620, an auxiliary pusher 630, and a limit return assembly. The bushing 610 is fixed on the frame 100, the rotating shaft 620 is rotatably connected to the bushing 610, the auxiliary pusher 630 is fixed at the end of the rotating shaft 620 away from the bushing 610, and the limit return assembly is used to limit the rotation angle of the rotating shaft 620 and can drive the rotating shaft 620 back to its original position. For dust prevention, a matching dustproof shell is provided outside the bushing 610, the rotating shaft 620, and the limit return assembly, and the auxiliary pusher 630 is located outside the dustproof shell.
[0070] The limit return assembly includes a limit stop 640, a passive adsorption component 650, an active adsorption component 660, and a return spring 670. The limit stop 640 and the active adsorption component 660 are fixed at intervals on the outer wall of the bushing 610. The passive adsorption component 650 is fixed on the rotating shaft 620. The active adsorption component 660 and the passive adsorption component 650 are magnetically attracted. The rotating shaft 620 can drive the passive adsorption component 650 to rotate within the range limited by the limit stop 640 and the active adsorption component 660, so that the auxiliary pusher 630 rotates to the pushing state or returns to its original position. The two ends of the return spring 670 are respectively fixed on the end faces of the passive adsorption component 650 and the active adsorption component 660 away from the bushing 610. The return spring 670 is used to assist the passive adsorption component 650 in returning to its original position.
[0071] In use, release the self-locking of the casters and push the entire transfer device to move its position. For easier pushing, an auxiliary pushing device 600 is provided. When the auxiliary pushing device 600 is not in use, the auxiliary pusher 630 remains in a vertical position (i.e., Figures 1-3 When using the auxiliary pushing device 600, rotate the auxiliary pusher 630 to a convenient pushing angle for pushing. At this time, the force applied to the rotating shaft 620 is greater than the magnetic attraction between the active adsorption component 660 and the passive adsorption component 650. The passive adsorption component 650 rotates with the rotating shaft 620 from the active adsorption component 660 towards the limit stop component 640, and the return spring 670 is in a stretched state. During use, a force is continuously applied to the rotating shaft 620 to keep the auxiliary pusher 630 in a horizontal state or other convenient pushing angle. When the rotation assistance is stopped, the force applied to the rotating shaft 620 is removed. Under the action of magnetic attraction, the passive adsorption component 650 drives the rotating shaft 620 to return to its position. At this time, the return spring 670 provides tension, and the auxiliary rotating shaft 620 returns to its position until the passive adsorption component 650 and the active adsorption component 660 are in contact. The rotating shaft 620 fixing the passive adsorption component 650 also rotates, causing the auxiliary pusher 630 to change from a convenient pushing angle to a vertical state.
[0072] The active adsorption component 660 and the passive adsorption component 650 can be passive magnetic attraction (non-electrically controlled). In this case, the active adsorption component 660 uses a permanent magnetic material (such as a neodymium iron boron permanent magnet) and can continuously generate a magnetic field without being energized. The passive adsorption component 650 uses a magnetically conductive material (such as iron, cobalt, nickel, and their alloys), which is non-magnetic but can be attracted by a permanent magnet. Alternatively, they can be active magnetic attraction (electrically controlled). In this case, the active adsorption component 660 is an electromagnetic coil assembly that generates a magnetic field (electromagnet) after being energized by the control device 400. The passive adsorption component 650 is made of a magnetically conductive metal (such as low-carbon steel) or a permanent magnet (with polarity compatible with the electromagnet).
[0073] Reference Figures 1 to 5 In some specific embodiments, the vertical displacement adjustment device 200 includes a first driving device 210, a transmission component 220 axially connected to the first driving device 210, and a transmission component connected to the transmission component 220; the transmission component includes a transmission chain 230, an inner connecting plate 240 connected to the transmission chain 230, and an outer connecting plate 260 fixed to the inner connecting plate 240, and the horizontal displacement adjustment device 300 is fixed on the outer connecting plate 260.
[0074] The first drive unit 210 includes a servo motor with brake and a reducer, which can realize functions such as output power, brake protection after power failure, and precise position control. The transmission component 220 includes a coupling, gears, and a transmission chain. The transmission component includes gears located at the top and bottom of the frame 100, a transmission chain 230 (which can be two parallel chains) sleeved on the gears, an inner connecting plate 240 connected to the transmission chain 230, and an outer connecting plate 260 fixed to the inner connecting plate 240. In order to adjust the tension of the transmission chain 230, a chain adjuster 250 is provided between the inner connecting plate 240 and the outer connecting plate 260. The two chain adjusters 250 are arranged opposite to each other on the inner connecting plate 240 and are respectively fixed to the links of the transmission chain 230. For dust protection, a housing 110 is provided covering the first drive unit 210 and the transmission component 220 shaft-connected to the first drive unit 210, and a bellows-shaped protective cover 120 is provided covering the transmission component.
[0075] This utility model also provides a transfer system, including a material cart, a sintering furnace, and a transfer device, the transfer device being used to transfer the parts to be transferred between the material cart and the sintering furnace.
[0076] Working Principle: When transferring the workpiece from the material cart to the sintering furnace, firstly, the control device 400 controls the horizontal displacement adjustment device 300 to move along the third direction (Z) to the same height as the workpiece placement station on the material cart (when the workpiece to be transferred is a graphite plate, due to the deformation of the graphite plate, the horizontal displacement adjustment device 300 needs to be slightly lower than the height of the workpiece placement station on the material cart). At this time, the stopping electromagnet 330 on the second beam frame 3114 near the material cart is in the pass state, and the stopping electromagnet 330 on the second beam frame 3114 near the sintering furnace is in the blocking state; the workpiece to be transferred is transferred from the material cart to the fixed support plate 312; secondly, when the second displacement detection device 342 detects that the workpiece to be transferred is in the second preset transfer position, the control device 400 controls the horizontal displacement adjustment device 300 to move along the vertical direction (third direction (Z)) until it is at the same height as the workpiece placement station in the sintering furnace (when the workpiece to be transferred is a graphite plate or other easily deformable workpiece, the horizontal displacement adjustment device 300 needs to be slightly higher than the height of the workpiece placement station in the sintering furnace). When the third displacement detector 343 detects that the workpiece to be transferred is in the third preset transfer position, the control device 400 controls the horizontal drive mechanism 314 to push the moving support plate 313 away from the fixed support plate 312 along the first direction X. At this time, the stop electromagnet 330 on the second beam 3114 near the material cart is in a blocking state, and the stop electromagnet 330 on the second beam 3114 near the sintering furnace is in a passing state. The workpiece to be transferred on the moving support plate 313 is transferred to the workpiece placement station in the sintering furnace. If the workpiece to be transferred is a easily deformable workpiece such as a graphite plate, when the fourth displacement detector 344 detects that the workpiece to be transferred is in the fourth preset transfer position, height compensation is performed, and the control device 400 controls the horizontal displacement adjustment device 300 to move along the vertical direction (third direction Z) until it is at the same height as the workpiece placement station in the sintering furnace. During this transfer process, the width limiting bar 350 set on the horizontal platform 310 is used to prevent the workpiece to be transferred from leaving the horizontal platform 310. When transferring the workpiece to be transferred from the sintering furnace to the material cart, the process is the reverse of the above, and will not be described again here.
[0077] Advantages of this utility model:
[0078] 1. High-precision transport assurance: Through the coordinated operation of the vertical displacement adjustment device 200 and the horizontal displacement adjustment device 300, the position of the horizontal platform 310 in three-dimensional space can be precisely controlled. Simultaneously, four sets of platform leveling devices 360 can precisely control the levelness of the adjustment, adapting to extreme working conditions with inclined ground, effectively preventing the transported parts from tipping over and being scrapped due to the tilting of the transport device. This is particularly suitable for transporting easily deformable transported parts such as graphite plates with strict levelness requirements. The anti-offset positioning component 370, through the sliding pair formed by the guide post 372 and the guide channel 373, only allows the first support frame 311 to move in the vertical direction. The four sets of anti-offset positioning components 370 completely constrain the horizontal translation and rotational freedom around the vertical axis, ensuring the relative positional accuracy of the two frames during platform leveling and preventing offset during the leveling process.
[0079] 2. High degree of intelligence and automation: Four displacement detection elements, spaced apart on the first beam frame 3113, correspond to four preset transfer positions, enabling real-time monitoring of the center of gravity transfer status of the parts to be transferred between the material cart, fixed support plate 312, movable support plate 313, and sintering furnace. Based on the detection results, the control device 400 automatically controls the lifting and lowering of the vertical displacement adjustment device 200 and the movement of the horizontal drive mechanism 314, automating the transfer process between the material cart and the sintering furnace, reducing manual intervention, minimizing human error, and significantly improving transfer efficiency.
[0080] 3. Reliable limit design: The stop electromagnet 330 in the limit component switches states as needed, and together with the adjustable width limiting bar 350, it can effectively prevent parts of different widths from falling off the horizontal platform 310 during the transfer process, providing all-round limit protection for the parts to be transferred and ensuring the safety and stability of the transfer process.
[0081] 4. Excellent environmental adaptability and durability: The movable base 500 features two large and two small casters at its bottom, allowing for flexible steering and a self-locking function, facilitating the easy movement and positioning of the transfer device in different work areas. The limit return component of the auxiliary pushing device 600 ensures that the auxiliary pusher 630 automatically returns to a vertical position after use, making operation convenient and reliable. The design of the outer shell 110, the accordion guard 120, and the dustproof shell reduces mechanical wear caused by the intrusion of dust and other impurities, extending the service life of the equipment.
[0082] 5. Wide Applicability and Compatibility: The distance between the two 350mm width-limiting barriers is adaptively adjustable within a certain range, accommodating the transfer needs of various specifications of parts to be transferred. Furthermore, the overall design of the transfer device fully considers the needs of different industrial scenarios. Whether it's precision sintered parts in the semiconductor and photovoltaic industries, or similar transfer scenarios in other industries, this transfer device can achieve efficient, accurate, and safe material transfer, demonstrating broad application prospects.
