Description

Technical Field

[0001] The present invention relates to the technical field of vacuum sintering, and in particular to a transfer device and system. Background Art

[0002] Metal Powder Injection Molding (MIM) is a novel near-net-shape powder metallurgy technology developed by integrating modern plastic injection molding techniques into the field of powder metallurgy. The MIM process flow is as follows: 1. Mixing metal powder and binder, 2. Molding, 3. Degreasing, 4. Sintering, 5. Post-processing, and 6. Finishing. MIM offers high production throughput and easily controlled molding. However, this high production volume results in the loading and unloading of the transported parts (which include graphite plates and the products they carry, including the products to be sintered or sintered products. Some of these products are supported by ceramic plates, which are then placed on the graphite plates). Manual loading and unloading not only requires considerable physical effort but also requires high lifting and handling requirements. There must be no shaking or wobbling to prevent the transported parts from tipping over and potentially becoming scrapped after sintering. The unloading process is equally complicated. In order to improve the utilization rate of the furnace, the furnace is generally not completely cooled before unloading. The high-temperature sintering of the furnace makes the parts to be transferred in a high-temperature state. Manual unloading will cause unnecessary burns.

[0003] When using a transfer device for loading and unloading, the existing transfer device usually has vertical lifting and rolling transmission (such as a roller rack) or belt transmission functions. By replacing some manual operations with mechanical transmission, manpower input can be reduced and transfer efficiency can be improved. For example, a lifting device is used to adjust the height to dock different workstations, and rolling or belt transmission is used to achieve horizontal movement of the parts to be transferred, which reduces the physical exertion of manual handling to a certain extent. However, the existing technology still has safety hazards in high-temperature environments. In the unloading link, the temperature of the furnace body is extremely high (above one hundred degrees Celsius) after high-temperature sintering, and the parts to be transferred are in a high-temperature state. The existing transfer device completes material transfer only through lifting and transmission functions, resulting in the risk of burns from high-temperature radiation or direct contact when docking close to the furnace body. For example, when using a traditional roller rack or belt to transport high-temperature materials, the operator needs to adjust the position of the material at close range, which is prone to safety accidents due to heat dissipation from the furnace body or accidental slipping of the parts to be transferred.

[0004] Therefore, how to provide a transfer device and system that can smoothly and safely transfer the items to be transferred is a technical problem that technical personnel in this field urgently need to solve. Summary of the Invention

[0005] The purpose of the present invention is to address the defects and shortcomings in the existing technology and provide a transfer device and system that can smoothly and safely transfer the parts to be transferred, avoid the products from tipping over during the transfer process and causing the sintered parts to be transferred to be scrapped; avoid being too close to the furnace body when discharging the material, and avoid burns when transferring the parts to be transferred that have just been taken out of the furnace and are in a high temperature state.

[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0046] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is 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 3113; the third direction Z is the vertical direction between the second support frame 320 and the first support frame 311, and 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, the present invention provides a transfer device, including a frame 100, a vertical displacement adjustment device 200 installed 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 in the vertical direction (i.e., the third direction Z); the horizontal displacement adjustment device 300 includes a horizontal platform 310, the horizontal platform 310 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 with a fixed support plate 312, and the other end is slidably connected with a movable support plate 313, the movable support plate 313 moves away from or approaches the fixed support plate 312 in the horizontal direction, and the fixed support plate 312 can be aligned with the workpiece placement station on the material vehicle (i.e., the placement position of the workpiece to be transferred, the workpiece placement station on the material vehicle is multi-layered, and is arranged at intervals along the third direction Z, and each layer can place the workpiece to be transferred, The aligned 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 be aligned with the workpiece placement station in the sintering furnace (that is, the placement position of the workpiece to be transferred, the workpiece placement stations in the sintering furnace are multi-layered, and are arranged at intervals along the third direction Z. Each layer can place the workpiece to be transferred, and the aligned position is the workpiece placement station where the workpiece to be transferred is about to be placed) to transfer the workpiece to be transferred between the material vehicle and the sintering furnace; the horizontal displacement adjustment device 300 also includes a limit assembly arranged on the horizontal platform 310, and the limit assembly is used to prevent the workpiece to be transferred from leaving the horizontal platform 310; it also includes a control device 400, the control device 400 is electrically connected to the vertical displacement adjustment device 200, and the control device 400 includes a control panel 410 and a combination control key 420 for inputting control instructions, such as the vertical displacement adjustment device 200 is used to drive the horizontal displacement adjustment device 300 to move up and down in the vertical direction (that is, the third direction Z).

[0049] It can be understood that when the workpiece to be transferred is transferred from the material cart to the sintering furnace, first, the control device 400 is used to control 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 problem 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), and the workpiece to be transferred from the material cart to the fixed support plate 312; then, after the workpiece to be transferred is completely transferred to the fixed support plate 312, the control device 400 is used to control the horizontal displacement adjustment device 300 to move along the third direction Z to the same height as the workpiece placement station in the sintering furnace (when the workpiece to be transferred is a graphite plate, due to the deformation problem of the graphite plate, the horizontal displacement adjustment device 300 needs to be slightly higher than the workpiece placement station in the sintering furnace). The height of the workpiece placement station is adjusted so that when the workpiece to be transferred is subsequently transferred to the sintering furnace, after the center of gravity of the workpiece to be transferred is transferred to the sintering furnace, the horizontal displacement adjustment device 300 moves along the third direction Z to the same height as the workpiece placement station in the sintering furnace, so that the workpiece to be transferred can smoothly separate from the movable support plate 313); and pushes the workpiece to be transferred on the fixed support plate 312 to transfer to the movable 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 to the movable support plate 313; finally, pushes the movable support plate 313 along the first direction X on the first support frame 311 in the direction away from the fixed support plate 312, and approaches 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 movable support plate 313 to the workpiece placement station in the sintering furnace. During this transfer process, the limit assembly provided on the horizontal platform 310 is used to prevent the workpiece to be transferred from the horizontal platform 310. When transferring the workpiece to be transferred from the sintering furnace to the material vehicle, the above process is the opposite and will not be repeated here.

[0050] Reference Figure 8-Figure 9 In some specific embodiments, a horizontal driving mechanism 314 is provided on the first support frame 311, the moving end of the horizontal driving mechanism 314 is connected to the movable support plate 313, and the horizontal driving 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 3113 and a second beam 3114, the first beam 3113 is parallel to the first direction X, and the second beam 3114 is parallel to the second direction Y; a displacement detection component 340 is provided on the first beam 3113, the displacement detection component 340 is used to detect whether the to-be-transferred object has reached a preset transfer position, the displacement detection component 340 is electrically connected to the control device 400, and the control device 400 controls the horizontal displacement adjustment device 300 to move up and down in the vertical direction or controls the horizontal driving mechanism 314 to push the movable support plate 313 away from or toward the fixed support plate 312 in the horizontal direction based on the detection result of the displacement detection component 340.

[0051] It can be understood that the horizontal drive mechanism 314 includes a slider 3144, a slide rail 3143, an electric push rod 3141 and a connecting piece 3142. The slider 3144 is arranged on the movable support plate 313, and the slide rail 3143 is provided on the first support frame 311. The slider 3144 is slidingly connected to the slide rail 3143, and the electric push rod 3141 is electrically connected to the control device 400. The fixed end of the electric push rod 3141 is fixed on the first support frame 311, and the moving end is fixed to the movable support plate 313 through the connecting piece 3142; the movable support plate 313 is located above the inner frame 3111 and is slidingly 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 a linear motion guide 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 that the parts to be transferred on the fixed support plate 312 can be transported to the sintering furnace through the movable support plate 313; or the movable support plate 313 approaches the fixed support plate 312 along the first direction X, so as to transport the parts to be transferred in the sintering furnace to 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 assembly 340 includes a first displacement detection member 341 for detecting the first preset transfer position, a second displacement detection member 342 for detecting the second preset transfer position, a third displacement detection member 343 for detecting the third preset transfer position, and a fourth displacement detection member 344 for detecting the fourth preset transfer position. The first displacement detection member 341, the second displacement detection member 342, the third displacement detection member 343, and the fourth displacement detection member 344 are spaced apart on the first beam 3113 along the first direction X.

[0053] During the transfer process of the workpiece to be transferred from the material cart to the sintering furnace, when the center of gravity of the workpiece to be transferred is transferred from the material cart to the fixed support plate 312, the position where the end of the workpiece to be transferred in the moving direction covers the second displacement detection member 342 and is detected by the second displacement detection member 342 is considered to be the second preset transfer position. At this time, the control device 400 controls the horizontal displacement adjustment device 300 to move in 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 workpiece that is easily deformed, such as a graphite plate, 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 center of gravity of the workpiece to be transferred is transferred from the fixed support plate 312 to the movable support plate 313, the position where the end of the workpiece to be transferred in the moving direction covers the third displacement detection member 343 and is detected by the third displacement detection member 343 is considered to be 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 along the first direction X away from the fixed support plate 312. When the workpiece to be transferred is a workpiece that is easily deformed, such as a graphite plate, when the center of gravity of the workpiece to be transferred is transferred from the movable support plate 313 to the sintering furnace, the end of the workpiece to be transferred in the opposite direction of the moving direction (that is, the opposite direction of the first direction X) no longer covers the fourth displacement detection member 344 and the position not detected by the fourth displacement detection member 344 is deemed to be that the workpiece to be transferred is 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 in the vertical direction (the third direction Z) until it is at the same height as the workpiece placement station in the sintering furnace.

[0054] During the transfer process of the workpiece to be transferred from the sintering furnace to the material cart, when the center of gravity of the workpiece to be transferred is transferred from the sintering furnace to the movable support plate 313, the position where the end of the workpiece to be transferred in the moving direction covers the third displacement detection member 343 and is detected by the third displacement detection member 343 is considered to be 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 in the direction opposite to the first direction X toward the fixed support plate 312. When the workpiece to be transferred is completely transferred to the movable support plate 313, the position where the end of the workpiece to be transferred in the direction opposite to the moving direction (i.e., the direction opposite to the first direction X) no longer covers the fourth displacement detection member 344 and is not detected by the fourth displacement detection member 344 is considered to be 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 (third direction Z) until it is at the same height as the workpiece placement station on the material cart (when the workpiece to be transferred is a deformable workpiece such as a graphite plate, the horizontal displacement adjustment device 300 needs to be slightly higher than the workpiece placement station on the material cart). the height of the workpiece placement station); when the workpiece to be transferred is a workpiece that is easily deformed, such as a graphite plate, 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 the moving direction (i.e., the first direction X) no longer covers the first displacement detection member 341, and the position that is not detected by the first displacement detection member 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 in 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 first, second, third, and fourth displacement detection members 341, 342, 343, and 344 may be positioned differently depending on the size of the object being transported. The specific operational configuration of the control device 400, based on the detection results of the displacement detection assembly 340, for controlling the horizontal displacement adjustment device 300 to move vertically up and down, or for controlling the horizontal drive mechanism 314 to push the movable support plate 313 horizontally away from or toward the fixed support plate 312, is not limited; it is sufficient that the control function is achieved.

[0056] Reference Figure 8 In some specific embodiments, at least two auxiliary moving members 315 are spaced apart on the fixed support plate 312 and the movable support plate 313. The auxiliary moving members 315 are used to reduce friction between the object to be transferred and the fixed support plate 312 and the movable support plate 313. The auxiliary moving members 315 may be rollers, universal bearings, etc. If the object to be transferred is large and fits closely with the first beam 3113, the top surface of the first beam 3113 may also be provided with spaced apart auxiliary moving members 315.

[0057] Reference Figure 8 、 Figure 9 In some specific embodiments, the limiting assembly includes two stopping electromagnets 330 arranged on the surface of the second beam 3114. The stopping electromagnets 330 are arranged at intervals on the surface of the second beam 3114. The interval distance between adjacent stopping electromagnets 330 is less than the width of the object to be transferred. The stopping electromagnet 330 includes a blocking state for blocking the object to be transferred from passing through and a passing state for allowing the object to be transferred to pass through. The stopping electromagnet 330 is electrically connected to the control device 400.

[0058] It can be understood that, in the process of transferring the workpiece to be transferred from the material cart to the sintering furnace, when the horizontal displacement adjustment device 300 moves in the vertical direction (third direction Z) to the same height as the workpiece placement station on the material cart, the vertical displacement adjustment device 200 stops moving, and the stopping electromagnet 330 on the second beam 3114 close to the material cart is in a passing state, and the stopping electromagnet 330 on the second beam 3114 close to the sintering furnace is in a blocking state; after the transfer workpiece is completely transferred to the horizontal platform 310, the stopping electromagnet 330 on the second beam 3114 close to the material cart and the stopping electromagnet 330 on the second beam 3114 close to the sintering furnace are both in a blocking state, preventing The part to be transferred slides out of the horizontal platform 310 in the first direction X; when the horizontal displacement adjustment device 300 moves in the vertical direction (third direction Z) to the same height as the workpiece placement station in the sintering furnace (when the part to be transferred is a workpiece that is easily deformed, such as a graphite plate, the horizontal displacement adjustment device 300 is slightly higher than the height of the workpiece placement station in the sintering furnace), the vertical displacement adjustment device 200 stops moving, and the stopping electromagnet 330 on the second beam 3114 close to the material vehicle is in a blocking state, and the stopping electromagnet 330 on the second beam 3114 close to the sintering furnace is in a passing state, which facilitates the smooth transfer of the part to be transferred from the horizontal platform 310 to the sintering furnace (the workpiece placement station in the sintering furnace). In the process of transferring the part to be transferred from the sintering furnace to the material vehicle, the state of the stopping electromagnet 330 is opposite to the above process, which will not be repeated here.

[0059] Reference Figures 8 to 10 In some specific embodiments, the position limiting assembly also includes a width limiting assembly, which includes a width limiting bar 350 and a displacement adjustment device. The width limiting bar 350 is arranged on both sides of the width direction of the first support frame 311. The displacement adjustment 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 the transfer objects of different widths from leaving the horizontal platform 310.

[0060] It can be understood that the width limiting baffle 350 is placed on the protruding frame 316 of the first support frame 311, and the displacement adjustment device can be a bolt and a nut. The bolt passes through the adjustment long hole 351 opened on the width limiting baffle 350 and the screw hole 352 on the protruding frame 316 in turn, and is connected to the nut to fix the width limiting baffle 350 on the protruding frame 316 of the first support frame 311. The length of the adjustment long 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 realize automatic adjustment, the displacement adjustment device (which can be an electric push rod, an electric slide, a stepping motor + a 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 movable end of the displacement adjustment device is connected to the width limiting baffle 350. When the relative position between the width limiting baffle 350 and the first support frame 311 needs to be adjusted, the control device 400 controls the movement of the movable end of the displacement adjustment device and then pushes the width limiting baffle 350 to move synchronously to adjust the relative position between the width limiting baffle 350 and the first support frame 311 to prevent the transported parts of different widths from leaving 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 become tilted, and the parts to be transferred may fall over when being transported through the horizontal platform 310, causing the sintered parts to be transferred to be scrapped. 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 via 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 part of the ball screw 362 located between the two fixed bases 361 is sleeved with a movable base. 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] A second drive device 365 (which can be a manually adjustable leveling handwheel or an automatically adjustable drive motor, etc.) is fixed to the input end of the ball screw 362, and a locking member 366 is connected to a fixed base 361, which is used to limit the rotation of the ball screw 362 in the fixed base 361.

[0065] It is understandable that the uneven factory floor causes the horizontal platform 310 for transporting the parts to be transferred to be skewed. In this case, the first support frame 311 and the second support frame 320 are connected by four groups (usually rectangularly distributed) of table leveling devices 360. The bevel angles of the first wedge block 363 and the second wedge block 364 can be designed to be 15°~30° to form a self-locking structure; an electromagnetic or mechanical locking part 366 is set on the outside of the fixed base 361, and the ball screw 362 is locked after leveling to prevent rotation.

[0066] During use, the displacement amount that needs to be leveled is determined, and the second driving device 365 for leveling drives the ball screw 362 to rotate, and the mobile base is translated 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 surface conversion of the wedge block, the displacement in the second direction Y is converted into the third direction Z 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 precise adjustment of the flatness of the first support frame 311 is achieved; after reaching the target horizontality, 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 movable support plate 313 on the first support frame 311 are in a horizontal state, thereby preventing the transfer parts from tipping over when being transported through the horizontal platform 310.

[0067] Reference Figures 8 to 10 In some specific embodiments, the horizontal displacement adjustment device 300 also includes an anti-deviation positioning assembly 370. The anti-deviation positioning assembly 370 includes a guide member 371 provided on the first support frame 311 and a guide column 372 provided on the second support frame 320. The guide member 371 is provided with a guide channel 373 for passing through and limiting the moving direction of the guide column 372. The guide column 372 is inserted into the guide channel 373 and moves up and down in the vertical direction within the guide channel 373.

[0068] It will be appreciated that the guide posts 372 and guide channels 373 form a sliding pair, allowing the first support frame 311 to move only in the third direction Z (vertical) relative to the plane of the second support frame 320. The four sets of anti-drift positioning assemblies 370 fully constrain translational freedom in the first direction X / second direction Y and rotational freedom about the Z axis. When the table leveling device 360 adjusts the horizontality, the guide posts 372 slide synchronously up and down within the guide channels 373. When the table leveling device 360 adjusts the horizontality of the first support frame 311, the anti-drift positioning assemblies 370 ensure the relative positional accuracy of the two frames during the adjustment process.

[0069] In order to realize the position movement of the entire transfer device, refer to Figure 1-Figure 3 、 Figure 11-12In some specific embodiments, the frame 100 is fixed on a movable base, and the bottom of the movable base is provided with two large and two small self-locking universal wheels, including two large wheels 502 and two small wheels 501; an auxiliary pushing device 600 is fixed on the frame 100 for assisting in pushing the entire transfer device, and the auxiliary pushing device 600 includes a shaft sleeve 610, a rotating shaft 620, an auxiliary pusher 630 and a limit return assembly, the shaft sleeve 610 is fixed on the frame 100, the rotating shaft 620 is rotatably connected to the shaft sleeve 610, the auxiliary pusher 630 is fixed to the end of the rotating shaft 620 away from the shaft sleeve 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 to return; in order to prevent dust, a corresponding dustproof cover is provided outside the shaft sleeve 610, the rotating shaft 620 and the limit return assembly, and the auxiliary pusher 630 is located outside the dustproof cover;

[0070] The limit return assembly includes a limit stop 640, a passive adsorption component 650, an active adsorption component 660 and a return tension spring 670; the limit stop 640 and the active adsorption component 660 are fixed at intervals on the outer wall of the sleeve 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 to each other, and 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 push handle 630 rotates to the pushing state or returns; the end faces of the passive adsorption component 650 and the active adsorption component 660 away from the sleeve 610 are respectively fixed to the two ends of the return tension spring 670, and the return tension spring 670 is used to assist the passive adsorption component 650 to return.

[0071] When in use, the self-locking of the universal wheel is released and the entire transfer device is pushed to move. In order to facilitate pushing, an auxiliary pushing device 600 is provided for auxiliary pushing. When the auxiliary pushing device 600 is not in use, the auxiliary push handle 630 remains in a vertical state (i.e. Figure 1-Figure 3 When the auxiliary pushing device 600 is used, the auxiliary handle 630 is rotated to an angle that is convenient 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 along the rotating shaft 620 from the active adsorption component 660 to the limit stop component 640, and the return tension spring 670 is in a stretched state. During use, a force is continuously applied to the rotating shaft 620 to keep the auxiliary push handle 630 in a horizontal state or other angle state that is convenient for pushing. When the rotation assistance is stopped, the force acting on the rotating shaft 620 is canceled. Under the action of the magnetic attraction, the passive adsorption component 650 drives the rotating shaft 620 to return. At this time, the return tension spring 670 provides a pulling force to assist the rotating shaft 620 to return until the passive adsorption component 650 is attached to the active adsorption component 660. The rotating shaft 620 that fixes the passive adsorption component 650 also rotates accordingly, driving the auxiliary push handle 630 from the angle that is convenient for pushing to a vertical state.

[0072] The active attracting element 660 and the passive attracting element 650 can be passive magnetically attracted (non-electrically controlled). In this case, the active attracting element 660 is made of a permanent magnetic material (such as a neodymium iron boron permanent magnet) and can continuously generate a magnetic field without power. The passive attracting element 650 is made of a magnetically conductive material (such as iron, cobalt, nickel, and their alloys). It is non-magnetic but can be attracted by a permanent magnet. Alternatively, they can be active magnetically attracted (electrically controlled). In this case, the active attracting element 660 is an electromagnetic coil assembly that generates a magnetic field (electromagnet) when powered by the control device 400. The passive attracting element 650 is made of a magnetically conductive metal (such as mild steel) or a permanent magnet (matching the polarity of 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 on 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 a brake and a reducer, enabling functions such as power output, brake protection after power failure, and precise position control. The transmission assembly 220 includes couplings, gears, and a transmission gear chain. The transmission assembly comprises gears located at the top and bottom ends of the frame 100, a transmission chain 230 (two transmission chains 230 can be arranged side by side) mounted 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. 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 positioned opposite each other on the inner connecting plate 240 and are fixed to the links of the transmission chain 230. To prevent dust, a housing 110 is provided to cover the first drive unit 210 and the transmission assembly 220 axially connected to the first drive unit 210, as well as an accordion protective cover 120 covering the transmission assembly.

[0075] The present invention also provides a transfer system, including a material vehicle, a sintering furnace and a transfer device, wherein the transfer device is used to transfer the parts to be transferred between the material vehicle and the sintering furnace.

[0076] Working principle: When transferring the workpiece to be transferred from the material cart to the sintering furnace, first, 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 problem 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 stop electromagnet 330 on the second beam 3114 close to the material cart is in a passing state, and the stop electromagnet 330 on the second beam 3114 close to the sintering furnace is in a blocking state; the workpiece to be transferred from the material cart to the fixed support plate 312; secondly, when the second displacement detection member 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 workpiece that is easily deformed, such as a graphite plate, 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 detection member 343 detects that the part to be transferred is in the third preset transfer position, the control device 400 controls the horizontal drive mechanism 314 to push the mobile 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 close to the material vehicle is in a blocking state, and the stop electromagnet 330 on the second beam 3114 close to the sintering furnace is in a passing state. The part to be transferred on the mobile support plate 313 is transferred to the workpiece placement station in the sintering furnace. If the part to be transferred is a workpiece that is easily deformed, such as a graphite plate, the fourth displacement detection member 344 detects that the part to be transferred is in the fourth preset transfer position, and height compensation is performed. The control device 400 controls the horizontal displacement adjustment device 300 to move in 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 barrier 350 provided on the horizontal platform 310 is used to prevent the part to be transferred from the horizontal platform 310. When transferring the part to be transferred from the sintering furnace to the material vehicle, the above process is the opposite and will not be repeated here.

[0077] Advantages of the present invention:

[0078] 1. High-precision transfer guarantee: 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 accurately controlled. At the same time, the four sets of table leveling devices 360 can accurately control the horizontality accuracy of the adjustment, adapt to the extreme working conditions of the tilted ground, and effectively avoid the transfer parts to be transferred from being overturned and scrapped due to the tilt of the transfer device. It is particularly suitable for the transfer of easily deformable parts to be transferred, such as graphite plates, which have strict requirements on horizontality. The anti-drift positioning assembly 370 forms a sliding pair through the guide column 372 and the guide channel 373, which only allows the first support frame 311 to move in the vertical direction. The four sets of anti-drift positioning assemblies 370 completely constrain the horizontal translation and the rotational freedom around the vertical axis, ensuring the relative position accuracy of the two layers of the frame during the table leveling process and avoiding offset during the leveling process.

[0079] 2. Highly intelligent and automated: Four displacement detectors, spaced apart on the first beam 3113, correspond to four preset transfer positions, enabling real-time monitoring of the center of gravity shift of the transferred component between the material cart, the fixed support plate 312, the movable support plate 313, and the sintering furnace. Based on the detection results, the control device 400 automatically controls 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. This reduces manual intervention, minimizes human error, and significantly improves transfer efficiency.

[0080] 3. Reliable limit design: The stop electromagnet 330 in the limit assembly switches its state according to the situation. Combined with the adjustable width-limiting bar 350, it can effectively prevent the transfer parts of different specifications and widths from leaving the horizontal platform 310 during the transfer process, providing all-round limit protection for the transfer parts and ensuring the safety and stability of the transfer process.

[0081] 4. Excellent Environmental Adaptability and Durability: The universal wheels on the bottom of the movable base 500 are designed with two large and two small wheels, providing flexible steering and a self-locking function, allowing for flexible movement and positioning of the transfer device in different work areas. The limit return assembly of the auxiliary pusher 600 automatically resets the auxiliary push handle 630 to a vertical position after use, providing convenient and reliable operation. The design of the housing 110, accordion protective cover 120, and dust cover reduces mechanical wear caused by the intrusion of dust and other impurities, thereby extending the service life of the equipment.

[0082] 5. Wide Applicability and Compatibility: The distance between the two 350-degree width-limiting bars is adaptively adjusted within a certain range, accommodating a wide range of transfer requirements for parts of various sizes. Furthermore, the overall design of the transfer device fully considers the needs of diverse industrial scenarios. Whether it is 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 its broad application prospects.
