Description

Technical Field

[0001] This application relates to the field of material handling and transfer technology, and in particular to a material loading and unloading mechanism and a powder forming equipment. Background Technology

[0002] Powder molding equipment typically includes a powder molding press, a transfer trolley, and a feeding mechanism. The powder molding press presses powder material filled into the mold cavity of the die panel to form a pressed material. A robotic arm then grips the pressed material and places it into the mold slot of an empty graphite plate in the feeding mechanism. Once the graphite plate is full, it is transferred to the transfer trolley, and then the empty graphite plates on the transfer trolley are placed onto the feeding mechanism to continue the next pressing material placement operation, thus completing the loading and unloading operations between empty and full plates.

The bidirectional telescopic component can extend and retract along the length direction of the carrier to switch between a carrier position in which the first pick-and-place position is exposed and a non-carrier position in which the first pick-and-place position is hidden in the base.

[0016] In some embodiments, along the telescopic direction of the bidirectional telescopic assembly, the bidirectional telescopic assembly includes at least two opposing automatic telescopic structures, which can move toward each other to the load-bearing position or toward each other to the non-load-bearing position.

[0022] Secondly, embodiments of this application provide a loading and unloading mechanism, including a powder forming press and a loading and unloading mechanism.

[0023] The beneficial effects of this utility model are: This application provides a loading and unloading mechanism and a powder forming device. The loading and unloading mechanism includes a bidirectional plate-pulling mechanism, a plate-changing mechanism located on opposite sides of the bidirectional plate-pulling mechanism, and a transfer mechanism. The bidirectional plate-pulling mechanism has a bearing position for placing a carrier component, the plate-changing mechanism has a first pick-and-place position for placing the carrier component, and the transfer mechanism has a second pick-and-place position for placing the carrier component. In this embodiment, the following is provided: The drive system is in transmission cooperation with the bidirectional pull-out mechanism to drive at least part of the bidirectional pull-out mechanism to move, so that the bearing position can be moved to a position corresponding to either the first pick-up position or the second pick-up position. Under the drive of the drive system, the bearing member is lifted upward. Then, under the drive of the drive system, the bearing position is moved to a position corresponding to the other of the first pick-up position and the second pick-up position, and the bearing member is supported on the other of the first pick-up position and the second pick-up position. This realizes the automated transfer operation of the bearing member on the first pick-up position and the bearing member on the second pick-up position, that is, realizes the automated loading and unloading operation.

[0024] For example, when it is necessary to transfer an empty carrier from the second pick-up and place position to the first pick-up and place position for holding the pressure material, at least a part of the bidirectional pull plate mechanism can be moved towards the direction of the second pick-up and place position under the drive of the drive system, so that the carrier position moves to the position corresponding to the second pick-up and place position and then lifts upward to support the carrier. Then, the drive system drives at least a part of the bidirectional pull plate mechanism to move towards the direction of the first pick-up and place position, so that the carrier position moves to the position corresponding to the first pick-up and place position, so that the empty carrier can be placed on the first pick-up and place position for subsequent pressure material holding operations.

[0025] Once the carrier at the first pick-up and drop-off position is full, the drive system can drive at least a portion of the bidirectional pull-out mechanism to move toward the direction closer to the first pick-up and drop-off position, placing the full carrier at the position. Then, the drive system can drive at least a portion of the bidirectional pull-out mechanism to move toward the direction closer to the second pick-up and drop-off position, finally placing the full carrier at the second pick-up and drop-off position. This achieves automatic transfer between empty and full carriers, enabling seamless connection between loading and unloading. The entire operation is highly efficient and automated, effectively saving manpower and time. Attached Figure Description

[0029] In the embodiments of this application, the terms "first," "second," "third," "fourth," "fifth," and "sixth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," "third," "fourth," "fifth," and "sixth" may explicitly or implicitly include one or more of that feature.

[0030] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0031] Reference Figures 1 to 9 As shown, this application embodiment provides a loading and unloading mechanism, including a bidirectional plate-pulling mechanism 100, a plate-changing mechanism 200 located on opposite sides of the bidirectional plate-pulling mechanism 100, and a transfer mechanism 300.

[0032] The bidirectional pull-out mechanism 100 is provided with a bearing position 110 for placing the bearing 400, the plate changing mechanism 200 has a first pick-and-place position 210 for placing the bearing 400, and the transfer mechanism 300 has a second pick-and-place position 310 for placing the bearing 400.

[0033] The drive system is in transmission cooperation with the bidirectional drawer mechanism 100 to drive at least a portion of the bidirectional drawer mechanism 100 to move such that the bearing position 110 moves to a position corresponding to either the first pick-up position 210 or the second pick-up position 310 and lifts the bearing member 400 upwards, and then moves the bearing position 110 to a position corresponding to the other of the first pick-up position 210 and the second pick-up position 310, and supports the bearing member 400 on the other of the first pick-up position 210 and the second pick-up position 310. In specific implementation, the loading and unloading mechanism is partially housed within the outer casing 510 of the powder forming equipment 500. Specifically, the bidirectional plate-pulling mechanism 100 and the plate-changing mechanism 200 can be housed within the casing 510, while the transfer mechanism 300 is located outside the casing 510. The casing 510 has corresponding openings for transferring the load-bearing component 400 between the bidirectional plate-pulling mechanism 100 and the transfer mechanism 300. The plate-changing mechanism 200 and the transfer mechanism 300 are respectively located on both sides of the bidirectional plate-pulling mechanism 100, facilitating the transfer of the load-bearing component 400 between the bidirectional plate-pulling mechanism 100 and its respective transfer mechanism 300 and plate-changing mechanism 200.

[0034] Specifically, the transfer mechanism 300 is mainly used to provide empty carriers 400 to the plate changing mechanism 200 and transport full carriers 400 on the plate changing mechanism 200 to a designated location. The bidirectional plate pulling mechanism 100, driven by the drive system, realizes the transfer operation between empty and full carriers 400.

[0035] For example, before the pressing operation, an empty carrier 400 needs to be placed on the first pick-up and place position 210 of the plate changing mechanism 200 to hold the pressed material formed by the powder forming press 520 of the powder forming equipment 500. That is, the empty carrier 400 on the second pick-up and place position 310 of the transfer mechanism 300 needs to be transferred to the first pick-up and place position 210. At this time, at least a part of the bidirectional plate pulling mechanism 100 can be moved by the drive system, so that at least a part of the bidirectional plate pulling mechanism 100 moves toward the direction closer to the second pick-up and place position 310, so that... The bearing position 110 can be moved to correspond to the position of the second pick-up and place position 310, and the empty bearing member 400 on the second pick-up and place position 310 is lifted upward to realize the bearing member 400 on the bearing position 110. Then, the drive system drives at least part of the bidirectional pull plate mechanism 100 to move towards the first pick-up and place position 210, so that the bearing position 110 moves to correspond to the position of the first pick-up and place position 210, and finally the empty bearing member 400 is placed on the first pick-up and place position 210 to facilitate the subsequent pressing and holding operation.

[0036] When the carrier 400 on the first pick-up and place position 210 is full, the bidirectional pull plate mechanism 100 can be driven by the drive system to move at least part towards the first pick-up and place position 210 until the position of the carrier 110 corresponds to the position of the first pick-up and place position 210. Then, it is lifted up to carry the full carrier 400 on the first pick-up and place position 210, and then moves towards the second pick-up and place position 310, and finally carries the full carrier 400 on the second pick-up and place position 310. By repeating the above process, the automatic transfer operation between the empty carrier 400 and the full carrier 400 can be realized an unlimited number of times, so as to achieve seamless connection of loading and unloading. The whole operation has high efficiency and automation, which can effectively save manpower and time.

[0037] For example, for the support member 400 placed at the first pick-up position 210 or the second pick-up position 310, the above-mentioned position can be that the support position 110 is located directly below or to the side of the first pick-up position 210 or the second pick-up position 310, or in the space between the two oppositely arranged support parts forming the first pick-up position 210 or the second pick-up position 310. In this case, after the support position 110 moves into place, it can be pushed upward to lift the support member 400 at the first pick-up position 210 or the second pick-up position 310, so as to realize the pick-up operation of the support member 400.

[0038] For the carrier 400 to be carried or placed at the first pick-up position 210 or the second pick-up position 310, the corresponding position can be that the carrier position 110 is located directly above or to the side of the first pick-up position 210 or the second pick-up position 310, or in the space between the two oppositely arranged support parts forming the first pick-up position 210 or the second pick-up position 310. At this time, after the carrier position 110 moves into place, it can fall down and place the carrier 400 on the first pick-up position 210 or the second pick-up position 310.

[0039] For example, the first pick-up and place position 210 and the second pick-up and place position 310 can both be pick-up and place positions formed by two oppositely arranged support parts. The space below the two support parts and the space between the two support parts can be inserted into the bidirectional pull-out mechanism 100 so that after the bearing position 110 is inserted into the space, the bearing member 400 on the first pick-up and place position 210 or the second pick-up and place position 310 can be just mounted on the bearing position 110. Then, as the bearing position 110 moves upward, the bearing member 400 on the first pick-up and place position 210 or the second pick-up and place position 310 can be supported on the bearing position 110 and transferred away with the movement of the bidirectional pull-out mechanism 100, thereby realizing the transfer and bearing operation of the bearing member 400 between different mechanisms.

[0040] For example, the bearing position 110, the first pick-up and place position 210 and the second pick-up and place position 310 are all used to place the bearing 400. The second pick-up and place position 310 can first place an empty bearing 400, and then drive at least part of the bidirectional pull plate mechanism 100 to move through the drive system, so that the empty bearing 400 is carried on the bearing position 110 and finally placed on the first pick-up and place position 210. After the bearing 400 on the first pick-up and place position 210 is full, the full bearing 400 is transferred back to the second pick-up and place position 310 after passing through the bearing position 110. At this time, the bearing 400 on the second pick-up and place position 310 is a full bearing 400, so as to realize one loading and unloading operation.

[0041] In practical use, the transfer mechanism 300 can be a transfer cart, which can be equipped with multiple second pick-up and drop-off positions 310. In the initial state, each second pick-up and drop-off position 310 is equipped with an empty carrier 400. After being transferred to the plate changing mechanism 200 to complete the loading operation, the carriers are returned to the second pick-up and drop-off positions 310. Once all the carriers 400 on the second pick-up and drop-off positions 310 are full, they can be transferred to a designated location by the transfer cart, and then a batch of empty carriers 400 can be placed to continue the above loading and unloading operations.

[0042] For example, the carrier 400 may be a graphite plate or other carrier capable of carrying materials.

[0043] Reference Figures 3 to 7As shown, in some embodiments, the bidirectional drawer mechanism 100 includes a base 120, a first movable plate 130 and a second movable plate 140 that are driven by a drive system.

[0044] The first movable plate 130 is disposed on the base 120 and can be moved or reset relative to the base 120 toward one of the first pick-up and place positions 210 and 310 under the drive of the drive system. The second movable plate 140 is disposed on the first movable plate 130, and at least a portion of the second movable plate 140 can be moved or reset toward the other of the first pick-up and place positions 210 and 310 under the drive of the drive system. The bearing position 110 is disposed on the second movable plate 140.

[0045] In specific implementation, the first movable plate 130 is disposed on the base 120 and can move towards one of the first pick-up and place positions 210 and 310 or move away from one of the first pick-up and place positions 210 and 310 to a reset position under the drive of the drive system, thereby realizing the transfer operation of the carrier 400 on one of the first pick-up and place positions 210 and 310. At least a portion of the second movable plate 140 can move towards the other of the first pick-up and place positions 210 and 310 or move away from the other of the first pick-up and place positions 210 and 310 to a reset position under the drive of the drive system, thereby realizing the transfer operation of the carrier 400 on the other of the first pick-up and place positions 210 and 310.

[0046] It should be noted that since the second movable plate 140 is disposed on the first movable plate 130, the movement of the first movable plate 130 will drive the entire second movable plate 140 to move. Since the bearing position 110 is disposed on the second movable plate 140, when the first movable plate 130 moves, it will also drive the bearing member 400 on the bearing position 110 to move, thereby enabling the transfer of the bearing member 400 between the bearing member 400 and the first pick-and-place position 210 or the second pick-and-place position 310. Furthermore, when at least a part of the second movable plate 140 itself moves, it will also drive the bearing member 400 disposed on the bearing position 110 of the second movable plate 140 to move, thereby enabling the transfer of the bearing member 400 between the bearing member 400 and the first pick-and-place position 210 or the second pick-and-place position 310.

[0047] For example, in this embodiment, the first movable plate 130 is disposed on the base 120 and can be moved or reset relative to the base 120 toward the direction of approaching the second pick-up and put-down position 310, and at least a portion of the second movable plate 140 can be moved or reset toward the direction of approaching the first pick-up and put-down position 210.

[0048] For ease of description, the second pick-up and drop position 310 and the first pick-up and drop position 210 can be assumed to be set in a front-to-back direction.

[0049] When it is necessary to transfer the carrier 400 on the second pick-up and place position 310 to the first pick-up and place position 210 to realize the loading operation of the empty carrier 400, the first moving plate 130 moves relative to the base 120 toward the second pick-up and place position 310 (moves backward) under the drive of the drive system. For example, when it moves to the bottom of the second pick-up and place position 310 or is level with the height of the second pick-up and place position 310, it lifts upward to carry the empty carrier 400 on the second pick-up and place position 310. After the first moving plate 130 completes the extension operation, it moves in the opposite direction to the reset (moves forward to the initial position) under the drive of the drive system.

[0050] Subsequently, at least a portion of the second moving plate 140 moves forward towards the first pick-up and place position 210 under the drive of the drive system. For example, when it moves to the same height as or above the first pick-up and place position 210, as the bearing position 110 continues to move forward, the bearing member 400 can be moved horizontally to the first pick-up and place position 210 or moved above the first pick-up and place position 210. After falling a certain height, the bearing member 400 is lowered onto the first pick-up and place position 210 and then exits the first pick-up and place position 210. This achieves the operation of the empty bearing member 400 on the bearing position 110 supporting the first pick-up and place position 210. At this time, after the second moving plate 140 completes the forward extension operation, it moves backward to the reset position under the drive of the drive system. At this time, the empty bearing member 400 on the first pick-up and place position 210 can be used for subsequent material loading operations.

[0051] When the carrier 400 on the first pick-up and place position 210 is full, it is necessary to transfer the carrier 400 on the first pick-up and place position 210 to the second pick-up and place position 310 to realize the unloading operation of the full carrier 400. At this time, at least part of the second moving plate 140 moves towards the direction of the first pick-up and place position 210 (moves forward) under the drive of the drive system. For example, when it moves to the bottom of the first pick-up and place position 210 or is level with the height of the first pick-up and place position 210, it lifts up and carries the full carrier 400 on the first pick-up and place position 210 on the carrier position 110. After the second moving plate 140 completes the forward extension operation, it moves in the opposite direction to the reset (moves backward to the initial position) under the drive of the drive system. Then, the first moving plate 130 moves relative to the base 120 toward the second pick-up / placement position 310 (moves backward). For example, when it moves to the same height as or above the second pick-up / placement position 310, as the bearing position 110 continues to move backward, the bearing 400 can be moved horizontally onto the second pick-up / placement position 310 or moved above the second pick-up / placement position 310, and then lowered a certain height to place the bearing 400 onto the second pick-up / placement position 310 and then exit the second pick-up / placement position 310. This achieves the final transfer of the full bearing 400 on the bearing position 110 of the first moving plate 130 to the second pick-up / placement position 310, realizing the unloading operation. After the unloading is completed, the first moving plate 130 moves in the opposite direction to the reset position (moves forward to the initial position) under the drive of the drive system.

[0052] Reference Figures 3 to 7 As shown, in some embodiments, the drive system includes a first drive element and a first transmission component.

[0053] The first driving component is in transmission cooperation with the first transmission assembly, the first transmission assembly is connected to the first moving plate 130, the first driving component is used to drive the first transmission assembly to move and link the first moving plate 130 to move; the second moving plate 140 is disposed on the first moving plate 130.

[0054] For example, when the first moving plate 130 needs to move toward the direction of approaching the second pick-up and place position 310 to carry the empty carrier 400 on the second pick-up and place position 310, the first driving member drives the first transmission assembly to move, and drives the first moving plate 130 to move toward the direction of approaching the second pick-up and place position 310. This, in turn, drives the second moving plate 140 set on the first moving plate 130 to move toward the direction of approaching the second pick-up and place position 310. Finally, the carrier position 110 moves to the position corresponding to the second pick-up and place position 310 and then lifts upward, so that the empty carrier 400 on the second pick-up and place position 310 is supported on the carrier position 110. The specific support process can be referred to the description above.

[0055] For example, the first driving component can be a drive motor or a drive cylinder.

[0056] Reference Figure 6 As shown, in some embodiments, the first transmission assembly includes a transmission screw and a transmission nut connected to the transmission screw, the first driving member is connected to the transmission screw, and the transmission nut is connected to the first moving plate 130.

[0057] In specific implementation, when the first moving plate 130 needs to move toward the direction of approaching the second pick-up and place position 310 to carry the empty carrier 400 on the second pick-up and place position 310, the first driving member can be set to rotate forward to drive the transmission screw to rotate. The rotation of the transmission screw drives the transmission nut on it to move. The movement of the transmission nut drives the first moving plate 130 to move toward the direction of approaching the second pick-up and place position 310, thereby driving the second moving plate 140 set on the first moving plate 130 to move toward the direction of approaching the second pick-up and place position 310 as a whole. Finally, the carrier position 110 moves to the position corresponding to the second pick-up and place position 310 and then lifts upward to support the empty carrier 400 on the second pick-up and place position 310 onto the carrier position 110.

[0058] When a reset is required, the first driving component can be reversed to drive the transmission screw to rotate. The rotation of the transmission screw causes the transmission nut on it to move away from the second pick-up and put-down position 310, and finally causes the first moving plate 130 to move away from the second pick-up and put-down position 310 to the reset position.

[0059] Alternatively, in other implementations, the first transmission component can also be a synchronous belt pulley transmission structure.

[0060] Reference Figures 3 to 7 As shown, in some embodiments, the drive system includes a second drive element 141 and a second transmission assembly 142.

[0061] The second driving member 141 is in transmission cooperation with the second transmission assembly 142. The second transmission assembly 142 is connected to the second moving plate 140. The second driving member 141 is used to drive the second transmission assembly 142 to move and move the second moving plate 140 in conjunction with it.

[0062] For example, when at least a portion of the second moving plate 140 needs to move toward the direction of the first pick-up and place position 210 to carry the full-loaded carrier 400 on the first pick-up and place position 210, the second driving member 141 drives the second transmission assembly 142 to move, and drives the second moving plate 140 to move toward the direction of the first pick-up and place position 210, thereby driving the carrier position 110 set thereon to move to the position corresponding to the first pick-up and place position 210 and then lift it upward, so that the full-loaded carrier 400 on the first pick-up and place position 210 can be supported on the carrier position 110.

[0063] For example, the second driving component 141 can be a drive motor or a drive cylinder.

[0064] Reference Figures 3 to 7 As shown, in some embodiments, the second transmission assembly 142 includes a main transmission wheel 144, a secondary transmission wheel 145, and a transmission belt 146 disposed on the main transmission wheel 144 and the secondary transmission wheel 145, and the second moving plate 140 is disposed on the transmission belt 146.

[0065] In specific implementation, when the second moving plate 140 needs to move towards the direction of the first pick-up and place position 210 to carry the full-loaded carrier 400 on the first pick-up and place position 210, the second driving member 141 can be set to rotate forward to drive the main drive wheel 144 to rotate. The rotation of the main drive wheel 144 drives the secondary drive wheel 145 to rotate through the transmission belt 146. The second moving plate 140 is set on the transmission belt 146. Therefore, when the transmission belt 146 rotates, it will drive the second moving plate 140 to move towards the direction of the first pick-up and place position 210, thereby driving the carrier position 110 set on it to move to the position corresponding to the first pick-up and place position 210 and then lift it upward, so that the full-loaded carrier 400 on the first pick-up and place position 210 can be supported on the carrier position 110.

[0066] When a reset is required, the second drive unit 141 can be reversed to drive the main drive wheel 144 to rotate. The rotation of the main drive wheel 144 drives the secondary drive wheel 145 to rotate through the drive belt 146. The second moving plate 140 is set on the drive belt 146. Therefore, when the drive belt 146 rotates, it will drive the second moving plate 140 to move away from the first pick-up and put-down position 210 to the reset position.

[0067] Reference Figure 6 As shown, in some embodiments, a limiting structure 150 is provided on one side of the opposite sides of the second moving plate 140 along the moving direction of the second moving plate 140, and a first moving limiting component 160 is provided on the other side of the opposite sides of the second moving plate 140.

[0068] The first movable limiting component 160 can move toward the limiting structure 150 to clamp the carrier 400 between the limiting structure 150 and the first movable limiting component 160, or move away from the limiting structure 150 to release the clamping limitation on the carrier 400.

[0069] In specific implementation, when the carrier 400 on the first pick-up position 210 or the second pick-up position 310 is placed on the carrier position 110, the carrier 400 can be moved and pushed by the first moving limiting component 160, so that the carrier 400 moves toward the limiting structure 150 and is finally clamped between the limiting structure 150 and the first moving limiting structure 150, so as to clamp and limit the carrier 400 and prevent the carrier 400 from falling.

[0070] When it is necessary to transfer the carrier 400 on the carrier position 110 to the first pick-up position 210 or the second pick-up position 310, the first moving limit assembly 160 can move away from the limit structure 150 to release the clamping of the carrier 400. At this time, the carrier 400 can be placed at the corresponding first pick-up position 210 or second pick-up position 310 when the carrier position 110 moves to the first pick-up position 210 or the second pick-up position 310.

[0071] For example, the limiting structure 150 may be at least two limiting plates spaced apart along a direction of movement perpendicular to the bearing position 110. The limiting structure 150 may be screwed onto the second moving plate 140 or snapped onto the first moving plate 130.

[0072] Reference Figure 6 and Figure 7 As shown, in some embodiments, the first moving limiting assembly 160 includes a third driving member 161 and a first stop portion 162 that is pulsatorically engaged with the third driving member 161. The third driving member 161 is disposed on the second moving plate 140, and the first stop portion 162 is located on the side of the third driving member 161 near the limiting structure 150, and can move towards or away from the limiting structure 150 under the drive of the third driving member 161.

[0073] In specific implementation, when the carrier 400 on the first pick-up position 210 or the second pick-up position 310 is placed on the carrier position 110, the third drive member 161 can drive the first stop 162 to move toward the direction of the limiting structure 150 to move and push against the carrier 400, so that the carrier 400 moves toward the limiting structure 150 and is finally clamped between the limiting structure 150 and the first stop 162, so as to clamp and limit the carrier 400 and prevent the carrier 400 from falling.

[0074] When it is necessary to transfer the carrier 400 on the carrier position 110 to the first pick-up position 210 or the second pick-up position 310, the third drive member 161 can drive the first stop 162 to move away from the limiting structure 150 to release the clamping of the carrier 400. At this time, when the carrier 400 moves from the carrier position 110 to the first pick-up position 210 or the second pick-up position 310, it can be placed at the corresponding first pick-up position 210 and second pick-up position 310.

[0075] For example, the third drive component 161 can be a linear motor or a cylinder. The first stop part 162 can be a stop plate, a stop disc, or a stop base, etc.

[0076] Reference Figures 3 to 7As shown, in some embodiments, the drive system further includes a lifting drive mechanism 170, which is disposed between the bidirectional drawing plate mechanism 100 and the inner wall of the housing 510 of the powder forming equipment 500, and is used to drive the bidirectional drawing plate mechanism 100 to lift.

[0077] This configuration allows the bidirectional pull-out mechanism 100 to adapt to the height of the first pick-up position 210 or the second pick-up position 310, so as to facilitate the transfer operation of the carrier 400 between the first pick-up position 210 and the second pick-up position 310.

[0078] Furthermore, when it is necessary to pick up or support the carrier 400 at the first pick-up position 210 or the second pick-up position 310, the lifting drive mechanism 170 can drive the carrier position 110 to descend below the first pick-up position 210 or the second pick-up position 310 and be directly opposite the carrier 400 on the first pick-up position 210 or the second pick-up position 310. Then, the carrier position 110 can be driven to move upward, thereby lifting the carrier 400 on the first pick-up position 210 or the second pick-up position 310. The carrier position 110 can also move the carrier 400 synchronously when it moves back and forth, thus realizing the picking operation of the carrier 400.

[0079] When it is necessary to place the carrier 400 on the first pick-up position 210 or the second pick-up position 310, the lifting drive mechanism 170 can drive the carrier position 110 to move upward above the first pick-up position 210 or the second pick-up position 310 and be directly opposite the carrier 400 on the first pick-up position 210 or the second pick-up position 310, and then drive the carrier position 110 to move downward, so that the carrier 400 can be lowered onto the first pick-up position 210 or the second pick-up position 310 to realize the placement operation of the carrier 400.

[0080] Reference Figures 3 to 9 As shown, in some embodiments, the first pick-up and / or the second pick-up and / or the second pick-up and / or the second pick-up and / or the second pick-up and / or the third pick-up and / or the fourth pick-up and the fifth pick-up and the sixth pick-up and the seventh pick-up and the eighth pick-up and the ninth pick-up and the tenon joint can be moved under the drive of the lifting drive mechanism 170 to correspond to any one of the first pick-up and the sixth pick-up and the seventh pick-up and the eighth pick-up and the ninth ...

[0081] Specifically, the second pick-up and place position 310 can be set to two, three, or four, etc., along the lifting direction. The first pick-up and place position 210 can be set to two, three, or four, etc., along the lifting direction. At this time, in order to enable the bearing position 110 to perform the transfer operation of the bearing 400 with the bearings 400 at the first pick-up and place positions 210 and 310 at different heights, thereby achieving seamless connection between loading and unloading, a lifting drive mechanism 170 can be set to drive the bidirectional pull plate mechanism 100 to lift as a whole, so as to facilitate the transfer operation of the bearings 400 placed at each of the first pick-up and place positions 210 and each of the second pick-up and place positions 310.

[0082] For example, taking the second pick-up and place position 310 as having two positions, one above the other, when it is necessary to transfer the carrier 400 placed in the upper second pick-up and place position 310, the lifting drive mechanism 170 can drive the bidirectional pull plate mechanism 100 to move so that the carrier position 110 moves to the bottom of the upper second pick-up and place position 310 and then lifts upwards, so as to support the empty carrier 400 in the upper second pick-up and place position 310 onto the carrier position 110.

[0083] When it is necessary to transfer the carrier 400 to the second pick-up and place position 310 below, the lifting drive mechanism 170 can drive the bidirectional pull plate mechanism 100 to move downward to the bottom of the second pick-up and place position 310 below the carrier position 110 and then lift it upward to support the empty carrier 400 at the second pick-up and place position 310 below onto the carrier position 110.

[0084] Reference Figures 3 to 5 As shown, in some embodiments, the lifting drive mechanism 170 includes a fourth drive member, which is connected to the bidirectional pull-out mechanism 100 and is used to drive the bidirectional pull-out mechanism 100 to lift.

[0085] For example, the fourth drive component can be a linear motor or a cylinder.

[0086] Reference Figures 3 to 5 As shown, in some embodiments, one of the bidirectional pull-out mechanism 100 and the housing 510 is provided with a first guide sliding part 171 extending along the lifting direction of the bidirectional pull-out mechanism 100, and the other of the bidirectional pull-out mechanism 100 and the housing 510 is provided with a second guide sliding part 511 that slides with the first guide sliding part 171, thereby realizing the sliding connection between the bidirectional pull-out mechanism 100 and the housing 510, and guiding the movement of the bidirectional pull-out mechanism 100 when it is lifted or lowered.

[0087] For example, one of the first guide sliding parts 171 is a groove, and the other is a slider that is slidably disposed within the groove. For instance, a groove can be provided on the inner wall of the housing 510, and a slider can be provided on the bidirectional drawer mechanism 100.

[0088] In addition, a receiving base plate 180 can be provided on the side of the bidirectional pull plate mechanism 100 facing the slide groove. The receiving base plate 180 is in transmission cooperation with the fourth driving member so that when the fourth driving member drives the receiving base plate 180 to rise and fall, it drives the entire bidirectional pull plate mechanism 100 to rise and fall.

[0089] Furthermore, a fixing plate 512 can be provided on the side of the housing 510 facing the lifting drive mechanism 170, and the lifting drive mechanism 170 can be slidably mounted on the fixing plate 512.

[0090] Reference Figures 3 to 5 , Figure 8 and Figure 9 As shown, in some embodiments, the plate changing mechanism 200 includes a base 220 and a bidirectional telescopic assembly 230.

[0091] The bidirectional telescopic assembly 230 is disposed on the base 220 and a first pick-up / placement position 210 is formed on the bidirectional telescopic assembly 230. The bidirectional telescopic assembly 230 can move along the length direction of the carrier 400 (refer to...). Figure 9 The device can be extended (in the x direction as shown) to switch between a load-bearing position in which the first pick-up and place position 210 is exposed and a non-load-bearing position in which the first pick-up and place position 210 is hidden within the base 220.

[0092] In practice, when it is necessary to place the carrier 400 on the first pick-up and place position 210 of the bidirectional telescopic assembly 230, the bidirectional telescopic assembly 230 can be extended to expose the first pick-up and place position 210 so that the carrier 400 can be placed on the first pick-up and place position 210.

[0093] When it is not necessary to place the carrier 400 on the first pick-up and place position 210 of the bidirectional telescopic assembly 230, the bidirectional telescopic assembly 230 can be retracted and the first pick-up and place position 210 can be hidden inside the base 220. At this time, the space between the bidirectional telescopic assemblies 230 can be used for other components to pass through without being disturbed by the first pick-up and place position 210 of the bidirectional telescopic assembly 230.

[0094] Reference Figure 8 and Figure 9As shown, in some embodiments, along the telescopic direction of the bidirectional telescopic assembly 230, the bidirectional telescopic assembly 230 includes at least two opposing automatic telescopic structures 231, which can move toward each other to a bearing position or toward each other to a non-bearing position; a portion of the top surface of all the automatic telescopic structures 231 together forms a first pick-and-place position 210.

[0095] In other words, when it is necessary to place the carrier 400 on the first pick-up and place position 210 of the bidirectional telescopic assembly 230, at least two oppositely arranged automatic telescopic structures 231 move and extend toward each other. At this time, parts of the two automatic telescopic structures 231 are exposed, and the top surfaces of all the automatic telescopic structures 231 can jointly form the first pick-up and place position 210 so as to place the carrier 400 on the first pick-up and place position 210.

[0096] When it is not necessary to place the carrier 400 on the first pick-up and put-down position 210 of the bidirectional telescopic assembly 230, at least two oppositely arranged automatic telescopic structures 231 move and retract in the direction away from each other. At this time, the two automatic telescopic structures 231 are hidden in the base 220. At this time, the space between the bidirectional telescopic assemblies 230 can be passed through by other components without being disturbed by the first pick-up and put-down position 210 of the bidirectional telescopic assembly 230.

[0097] For example, the automatic retractable structure 231 can be configured as two.

[0098] Reference Figure 8 and Figure 9 As shown, in some embodiments, the automatic telescopic structure 231 includes a fifth drive member 232 and a support plate 233 that is driven to cooperate with the fifth drive member 232. The fifth drive member 232 can drive the support plate 233 to move toward the support plate 233 on the other side to a bearing position or to move toward the support plate 233 on the other side away to a non-bearing position. The top surface of the support plate 233 forms a first pick-up and drop position 210.

[0099] When it is necessary to place the carrier 400 on the first pick-up and place position 210 of the bidirectional telescopic assembly 230, the fifth drive member 232 of each automatic telescopic structure 231 drives the carrier plate 233 to move toward the carrier plate 233 on the other side. At this time, at least two portions of the carrier plates 233 move into the space between the two oppositely arranged automatic telescopic structures 231 and are exposed. The first pick-up and place position 210 formed by the top surface of all the carrier plates 233 can be used to place the carrier 400.

[0100] Conversely, the support plate 233 can be moved to a non-load-bearing position, thus achieving concealment, allowing other components to pass through the space between the bidirectional telescopic components 230 without being disturbed by the first pick-up and put-down position 210 of the bidirectional telescopic components 230.

[0101] For example, the fifth drive component 232 can be a motor or a cylinder.

[0102] Reference Figure 8 and Figure 9 As shown, in some embodiments, at least two second movement limiting components 240 are also provided on the base 220. The at least two second movement limiting components 240 are respectively disposed on opposite sides of the first pick-up and place position 210, and can move toward each other and abut against opposite sides of the carrier 400 on the first pick-up and place position 210, or move away from each other to release the abutment against the carrier 400.

[0103] In practice, after the carrier 400 is placed on the first pick-up and put-down position 210, one side of the carrier 400 can be abutted against one of the second moving limit components 240, so that the other second moving limit component 240 moves toward the carrier 400 and finally the two second moving limit components 240 clamp and limit the carrier 400.

[0104] Alternatively, when the carrier 400 is placed in the first pick-up and drop position 210, at least two second movement limiting components 240 located on both sides of the carrier 400 can move toward the carrier 400 and eventually clamp the carrier 400 therein.

[0105] That is, in specific operation, only one of the second movement limiting components 240 on one side of the carrier 400 can be moved, while the second movement limiting component 240 on the other side can remain stationary. Alternatively, both the second movement limiting components 240 on both sides of the carrier 400 can be moved.

[0106] Conversely, the clamping operation on the carrier 400 can be released, which will not be elaborated here.

[0107] For example, there may be two second movement limiting components 240, that is, one second movement limiting component 240 is provided on each of the opposite sides of the bidirectional telescopic component 230.

[0108] Alternatively, in other implementations, a fixed limiting component can be provided on one side of the carrier 400, and a movable second moving limiting component 240 can be provided on the other side. When limiting and clamping, the carrier 400 can be pushed against the limiting component by the second moving limiting component 240, and then the carrier 400 can be clamped between the second moving limiting component 240 and the limiting component.

[0109] Specifically, the second moving limit assembly 240 includes a sixth driving member 241 and a second stop portion 242 that is in transmission cooperation with the sixth driving member 241. The sixth driving member 241 is disposed on the base 220, and the second stop portion 242 is located on one side of the sixth driving member 241 that is closer to the other side of the second stop portion 242. It can move towards or away from the other side of the second stop portion 242 under the drive of the sixth driving member 241 to realize the clamping or unclamping operation of the carrier 400.

[0110] For example, the sixth drive unit 241 can be a motor or a cylinder.

[0111] Reference Figures 3 to 5 , Figure 8 and Figure 9 As shown, in some embodiments, the plate changing mechanism 200 further includes a lifting assembly 250 located below the bidirectional telescopic assembly 230, and a first pick-and-place position 210 is formed on the side of the lifting assembly 250 near the bidirectional telescopic assembly 230.

[0112] When the bidirectional telescopic assembly 230 is retracted to a non-load-bearing position, the lifting assembly 250 can move toward the direction close to the bidirectional telescopic assembly 230 so that the second pick-up and put-down position 310 of the lifting assembly 250 is above the bidirectional telescopic assembly 230. The bidirectional telescopic assembly 230 is used to extend to a load-bearing position when the second pick-up and put-down position 310 of the lifting assembly 250 is above the bidirectional telescopic assembly 230 to support the load member 400 on the second pick-up and put-down position 310 of the lifting assembly 250.

[0113] In other words, the bidirectional telescopic component 230 of the plate changing mechanism 200 can be provided with a first pick-up and place position 210, and the side of the lifting component 250 facing the bidirectional telescopic component 230 can also be provided with a first pick-up and place position 210, that is, the plate changing mechanism 200 can be provided with two first pick-up and place positions 210. When the transfer mechanism 300 is also provided with at least two second pick-up and place positions 310, the bidirectional plate pulling mechanism 100 can realize the cyclic switching operation between the carrier 400 on different first pick-up and place positions 210 and the carrier 400 on different second pick-up and place positions 310, that is, the transfer operation between full and empty plates can be realized without interruption, so as to achieve seamless connection of loading and unloading. That is, the empty carrier 400 on the second pick-up and place position 310 is transferred to the first pick-up and place position 210, and the full carrier 400 on the first pick-up and place position 210 is transferred to the second pick-up and place position 310, and the above process is repeated to achieve seamless connection of loading and unloading.

[0114] In practice, the lifting assembly 250 is located below the bidirectional telescopic assembly 230. When the carrier 400 on the first pick-up and place position 210 of the bidirectional telescopic assembly 230 is full and removed by the bidirectional pull-out mechanism 100, and it is necessary to replenish the carrier 400 on the first pick-up and place position 210 of the lifting assembly 250 to the first pick-up and place position 210 of the bidirectional telescopic assembly 230, the bidirectional telescopic assembly 230 can retract to a non-load-bearing position, i.e., be hidden, to provide space for the lifting assembly 250 to move upward. At this time, at least a portion of the lifting assembly 250 moves towards the direction closer to the bidirectional telescopic assembly 230. The lifting assembly 250 continues to move until the carrier 400 on the lifting assembly 250 is positioned on the bidirectional telescopic assembly 230. At this point, the bidirectional telescopic assembly 230 extends to its bearing position, and the first pick-up / placement position 210 of the bidirectional telescopic assembly 230 extends. At least a portion of the lifting assembly 250 can then descend, placing the empty carrier 400 on the first pick-up / placement position 210 of the lifting assembly 250 onto the first pick-up / placement position 210 of the bidirectional telescopic assembly 230, before continuing to descend to its reset position. This replenishes the carrier 400 on the lifting assembly 250 to the first pick-up / placement position 210 of the bidirectional telescopic assembly 230 for material loading. Furthermore, the first pick-up / placement position 210 of the lifting assembly 250 can continue to transfer empty carriers 400 from the second pick-up / placement position 310 to the first pick-up / placement position 210 of the lifting assembly 250 via the bidirectional pull-out mechanism 100, replenishing the carrier 400. Meanwhile, after the carrier 400 on the first pick-up and place position 210 of the bidirectional telescopic assembly 230 is full, the carrier 400 is removed by the bidirectional pull plate mechanism 100 and transported to the second pick-up and place position 310. Then the above operation is repeated to achieve uninterrupted loading and unloading operation.

[0115] In other words, the first pick-up and place position 210 of the lifting assembly 250 is used to provide a buffer position for placing the carrier 400 and for subsequent replenishment to the first pick-up and place position 210 of the bidirectional telescopic assembly 230. Since the bidirectional telescopic assembly 230 is located above the lifting assembly 250, the carrier 400 on the first pick-up and place position 210 of the bidirectional telescopic assembly 230 is more convenient for placement of the pressing material and is less likely to be interfered with by the position of other components. Therefore, the first pick-up and place position 210 of the bidirectional telescopic assembly 230 is used as the operating area and the first pick-up and place position 210 of the lifting assembly 250 is used as a buffer.

[0116] Reference Figures 3 to 5 , Figure 8 and Figure 9 As shown, in some embodiments, the lifting assembly 250 includes a seventh drive member 251 and a lifting support assembly 252. The seventh drive member 251 is tractively connected to the lifting support assembly 252 and is used to drive the lifting support assembly 252 to move toward or away from the bidirectional telescopic assembly 230.

[0117] The side of the lifting support assembly 252 facing the bidirectional telescopic assembly 230 forms a second pick-and-place position 310.

[0118] Specifically, when it is necessary to replenish the empty carrier 400 on the first pick-up and place position 210 of the lifting assembly 250 to the first pick-up and place position 210 of the bidirectional telescopic assembly 230, the seventh drive member 251 drives the lifting support assembly 252 to move upward above the bidirectional telescopic assembly 230. At this time, the bidirectional telescopic assembly 230 extends to the first pick-up and place position 210. Then, the seventh drive member 251 drives the lifting support assembly 252 to descend, so that the carrier 400 falls to the first pick-up and place position 210 of the bidirectional telescopic assembly 230, realizing the replenishment operation of the carrier 400. Subsequently, the seventh drive member 251 drives the lifting support assembly 252 to fall and reset, and then the bidirectional pull plate mechanism 100 continues to replenish the next empty carrier 400 on the first pick-up and place position 210 of the lifting assembly 250. The above operation is continuously repeated until the production needs are met.

[0119] For example, the lifting support assembly 252 includes a lifting base plate 253 and at least two circumferentially spaced pillars 254 disposed on one side of the lifting base plate 253 facing the bidirectional telescopic assembly 230, the side of the pillars 254 facing the bidirectional telescopic assembly 230 forming a second pick-and-place position 310.

[0120] In addition, the top surface of the support column 254 can be provided with an inclined guide angle, which can guide and limit the bearing member 400.

[0121] Reference Figures 1 to 9 As shown in the figure, this application embodiment provides a powder forming equipment 500, including a powder forming press 520 and a loading and unloading mechanism.

[0122] The specific structure and implementation principle of the loading and unloading mechanism in this embodiment are the same as those of the loading and unloading mechanism provided in the above embodiments, and can bring the same or similar technical effects. They will not be described in detail here, but can be referred to the description of the above embodiments.

[0123] Specifically, the powder forming equipment 500 may also include a robot arm 530, a weighing mechanism 540, etc. The powder forming press 520 is used to batch press the powder filling multiple cavities in the mold panel 521 to form multiple pressed materials. Then, the robot arm 530 grabs the multiple pressed materials of the same batch onto the weighing mechanism 540 for individual weighing. After weighing, the robot arm 530 places the same batch of pressed materials into the multiple cavities of the carrier 400 on the first pick-up and place position 210 of the plate changing mechanism 200. The carrier 400 on the first pick-up and place position 210 is transferred to the second pick-up and place position 310 of the transfer mechanism through the bidirectional plate pulling mechanism 100 to realize the subsequent transportation operation.

[0124] In the description of the embodiments of this application, specific features, structures, materials or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0125] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
