[0047] The features and exemplary embodiments of the various aspects of the present application will be described in detail below with reference to the figures. For the purpose of clarity, the description is divided into the following sections: technical field; background; summary; detailed description; and drawings. It is to be understood that the foregoing general description and the following detailed description are merely intended to illustrate the application and its best mode. The application can be practiced with the exact details being omitted or substituted for other specific details in order to avoid obscuring the application or adding unnecessary restrictions while preservingscope of the application.

[0048] It should be noted that the relational terms herein, such as first and second, and the like, are used solely to distinguish one from another entity or action without necessarily requiring or implying any actual relationship or order between such entities or actions. Moreover, the terms "comprises", "comprising", or any other variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus. An element proceeded by "comprises... a" does not, without more constraints, exclude the existence of additional identical elements in the process, method, article, or apparatus that comprises the element.

[0049] In the product manufacturing process, the mold plays a vital role, through which the designed product shape can be efficiently and accurately copied, and the batch production of the product can also be carried out, so as to ensure that the produced products have consistent size and shape precision, greatly improve the production efficiency and speed, and reduce the manufacturing cost of single product.

[0050] In actual production process, the performance and maintenance condition of the mold directly affect the quality and production efficiency of the product, and before each shift operation, the mold needs to be washed and lubricated by using the rubber strip. In the process of washing and lubricating the mold, how to stably and conveniently transfer the rubber strip is an important problem.

[0051] In the related art, the rubber strip is transferred and placed into the mold by the technical personnel manually, however, many production molds are in a high temperature environment, and the technical personnel need to wear high temperature gloves to operate, which causes inconvenient operation.

[0052] In view of this, please refer to Figures 1 to 3The embodiment of the present application provides a material transfer device, which has a first state and a second state. The material transfer device comprises a base 10, a blocking structure 20 and a transmission assembly 30. The base 10 comprises a first limiting piece 11, a discharging channel 12 and a movable space 13 located on both sides of the first limiting piece 11 in a first direction X. The discharging channel 12 and the movable space 13 are arranged through the base 10 in a second direction Y, and the first direction X intersects the second direction Y. The blocking structure 20 is movably connected to the base 10. The blocking structure 20 comprises a constraint piece 21 and a material blocking piece 22 which are connected in a bent mode. The constraint piece 21 is located inside the movable space 13, and the transmission assembly 30 is transmissionally connected to the constraint piece 21. In the process of changing from the first state to the second state, the transmission assembly 30 drives the constraint piece 21 to gradually approach the surface of the movable space 13 towards the first limiting piece 11, and the overlapping area of the material blocking piece 22 and the projection of the discharging channel 12 in the second direction Y gradually increases.

[0053] The material transfer device provided by the embodiment of the present application can be used for some auxiliary materials required in production of related products. Taking production of semiconductor device products as an example, various molds are required in the production process of the related products of the semiconductor device. In order to facilitate demolding of the related products in the semiconductor device and reduce the probability of sticking, a rubber strip needs to be placed on the mold before each shift operation to wash and lubricate the mold. The material transfer device provided by the embodiment of the present application can be used for transferring the rubber strip. The technician first places the required rubber strip in the material transfer device, and then places the rubber strip on the mold through the material transfer device. It can be understood that the material transfer device provided by the present application can also be applied to other fields, which is not limited herein. In order to ensure the strength of the material transfer device, the material transfer device provided by the embodiment of the present application is made of aluminum alloy.

[0054] The material transfer device has the first state and the second state. In the first state, the material transfer device can carry the material and move the material to transfer the material to a required position. In the second state, the material transfer device releases the material to separate the material from the material transfer device.

[0055] Specifically, the material transfer device includes a base 10, a blocking structure 20 movably connected to the base 10, and a transmission assembly 30 transmission-connected to the blocking structure 20. The base 10 serves as the basic framework of the material transfer device and is formed with a material placement area. The blocking structure 20 is movably disposed relative to the base 10. In a first state, the blocking structure 20 is in a first position, confining the material to the material placement area on the base 10. In a second state, the blocking structure 20 is in a second position, releasing the material from the material placement area on the base 10, and the material is separated from the base 10. The transmission assembly is used to drive the blocking structure 20 to move, so that the blocking structure 20 is in the first position or the second position, thereby enabling the material transfer and release of the material by the material transfer device.

[0056] The base 10 is provided with a material discharge channel 12 that passes through the base 10 in a second direction Y. The blocking structure 20 includes a material blocking member 22. During the process of transitioning from the first state to the second state, the overlapping area of ​​the projection of the material blocking member 22 and the material discharge channel 12 in the second direction Y gradually increases. It can be understood that in the first state, the overlapping area of ​​the projection of the material blocking member 22 and the material discharge channel 12 in the second direction Y is the smallest. Optionally, the projection of the material blocking member 22 and the material discharge channel 12 in the second direction Y does not overlap. In the second state, the overlapping area of ​​the projection of the material blocking member 22 and the material discharge channel 12 in the second direction Y is the largest. Optionally, the projection of the material blocking member 22 and the material discharge channel 12 in the second direction Y completely overlaps.

[0057] When the material transfer device is in the second state, the material transfer device transfers the material, and the material is inside the discharge channel 12. The overlapping area between the material blocking member 22 and the projection of the discharge channel 12 in the second direction Y is the largest, and the material blocking member 22 carries the material in the second direction Y to confine the material inside the discharge channel 12. When the material transfer device changes from the second state to the first state, the overlapping area between the material blocking member 22 and the projection of the discharge channel 12 in the second direction Y gradually decreases, and the carrying area of ​​the material by the material blocking member 22 in the second direction Y also gradually decreases, but the material is still inside the discharge channel 12. When the material transfer device is in the first state, the overlapping area between the material blocking member 22 and the projection of the discharge channel 12 in the second direction Y is the smallest, and the material blocking member 22 cannot carry the material in the second direction Y, so that the material is separated from the material transfer device along the second direction Y from the discharge channel 12.

[0058] Further, the base 10 further comprises a first limiting piece 11 and a moving space 13 penetrating through the base 10 along the second direction Y, the moving space 13 is located at two sides of the first limiting piece 11 along the first direction X respectively. The blocking structure 20 further comprises a constraint piece 21 connected with the blocking piece 22 by bending, the constraint piece 21 is located inside the moving space 13, and the transmission assembly 30 is drivingly connected with the constraint piece 21. When the transmission assembly 30 drives the constraint piece 21 to move relative to the base 10, the blocking piece 22 will be driven to move relative to the base 10 as well. In the process of changing from the first state to the second state, the transmission assembly 30 drives the constraint piece 21 to gradually approach the surface of the first limiting piece 11 towards the moving space 13, and makes the projection overlap area of the blocking piece 22 and the discharging channel 12 in the second direction Y gradually increase.

[0059] In order to further optimize the arrangement position of the discharging channel 12 and the moving space 13, the first direction X and the second direction Y are preferably perpendicular. The first limiting piece 11 divides the discharging channel 12 and the moving space 13 in the first direction X, so that the discharging channel 12 and the moving space 13 do not interfere with each other. In the process of changing from the first state to the second state of the material transfer device, the material is always located inside the projection of the discharging channel 12 in the second direction Y, and the constraint piece 21 driving the blocking piece 22 to move is always located inside the projection of the moving space 13 in the second direction Y. The arrangement of the first limiting piece 11 can reduce the influence of the constraint piece 21 on the material, only the blocking piece 22 contacts the material, so as to ensure the position stability of the material on the material transfer device.

[0060] Meanwhile, in the process of changing from the second state to the first state, the first limiting piece 11 can limit the material inside the discharging channel 12, reduce the probability of the material moving with the blocking piece 22, so that the material can smoothly separate from the material transfer device. The bending connection between the constraint piece 21 and the blocking piece 22 can realize that the constraint piece 21 stably drives the blocking piece 22 to move, and on the other hand, in combination with the arrangement of the first limiting piece 11, the moving range of the blocking structure 20 can be limited by the cooperation of the first limiting piece 11 and the constraint piece 21, so as to adjust the relative position relationship of the blocking piece 22 relative to the discharging channel 12 in the second direction Y, and then stably load or conveniently separate the material.

[0061] In summary, in the material transfer device provided in the embodiments of the present application, the base 10 is formed with a position area for placing the material. The blocking structure 20 is movably arranged relative to the base 10. On the one hand, the blocking structure 20 can restrict the material to the position area of the base 10 for placing the material. On the other hand, the blocking structure 20 can release the restriction of the material to the position area of the base 10 for placing the material, so that the material is separated from the base 10. Specifically, the base 10 is provided with the discharging channel 12 in the second direction Y. When the blocking structure 20 is changed from the second state to the first state, the overlapping area between the blocking member 22 and the projection of the discharging channel 12 in the second direction Y gradually decreases, and the bearing area of the blocking member 22 for the material in the second direction Y also gradually decreases, so that the material is separated from the material transfer device by the discharging channel 12. At the same time, in order to facilitate the control of the movement of the blocking structure, the base 10 further comprises the first limiting member 11 and the movement space 13, and the discharging channel 12 is arranged on both sides of the first limiting member 11 in the first direction X. The first limiting member 11 divides the discharging channel 12 and the movement space 13 in the first direction X, so that the discharging channel 12 and the movement space 13 do not interfere with each other, the influence of the blocking member 21 on the material is reduced, and the material transfer device can stably bear and conveniently separate the material.

[0062] In some embodiments, the blocking structure 20 is arranged to slide relative to the first limiting member 11 in the first direction X. In the first state, the blocking member 21 is arranged to be spaced apart from the first limiting member 11 in the first direction X, and the blocking member 22 does not overlap with the projection of the discharging channel 12 in the second direction Y. In the second state, the blocking member 21 is arranged to abut against the first limiting member 11 in the first direction X, and the blocking member 22 at least partially overlaps with the projection of the discharging channel 12 in the second direction Y.

[0063] In the second state, the material is borne by the blocking member 22 in the second direction Y. During the change from the second state to the first state, the blocking structure 20 slides in the first direction X, the distance between the blocking member 21 and the first limiting member 11 in the first direction X gradually increases, and the projection area of the blocking member 22 in the second direction Y gradually decreases. During the sliding of the blocking structure 20 in the first direction X, the material is still inside the discharging channel 12 under the limiting action of the first limiting member 11. When the change is made to the first state, the blocking member 22 does not overlap with the projection of the discharging channel 12 in the second direction Y, and the material has no supporting structure in the second direction Y, so that the material is separated from the material transfer device.

[0064] In some embodiments, the first limiting member 11 is provided with a sliding hole 111 along the first direction X, and the blocking material 22 is at least partially inside the sliding hole 111 and is arranged to slide along the first direction X. Along the second direction Y, the two side surfaces of the blocking material 22 are respectively arranged in abutment with the two side hole walls of the sliding hole 111.

[0065] In order to limit the blocking structure 20 in the second direction Y and ensure the relative position relationship between the blocking structure 20 and the first limiting member 11 in the first direction X, the sliding hole 111 is arranged on the first limiting member 11, and the blocking material 22 is arranged inside the sliding hole 111, and the two side hole walls of the sliding hole 111 are used to limit the blocking material 22 in the second direction Y, so as to reduce the probability of position deviation of the blocking structure 20 in the second direction Y relative to the first limiting member 11. At the same time, the blocking material 22 is inside the sliding hole 111, which means that the position of the blocking material 22 in the second direction Y is inside the extension size of the first limiting member 11 in the second direction Y, so as to avoid the blocking material 22 protruding out of the first limiting member 11 in the second direction Y, and ensure the flatness of the one side surface of the first limiting member 11 and the base 10 in the second direction Y.

[0066] In some embodiments, along the third direction Z, the two side surfaces of the blocking material 22 are respectively arranged in abutment with the two side hole walls of the sliding hole 111, and the third direction Z, the second direction Y and the first direction X are all intersected with each other. Through the above arrangement, the sliding hole 111 can be used to limit the blocking material 22 in the third direction Z, so as to reduce the probability of sliding deviation of the blocking material 22 during the sliding process along the first direction X.

[0067] In some embodiments, referring to Figures 1 to 4 , the blocking structure 20 further comprises a stopper connected to the end of the blocking material 22 away from the constraint member 21, and the stopper is arranged to protrude away from the side of the blocking material 22 away from the constraint member 21 in the second direction Y. In the first state, the stopper is arranged in abutment with the first limiting member 11.

[0068] During the transition from the second state to the first state, the distance between the constraint member 21 and the first limiting member 11 in the first direction X gradually increases, and the blocking material 22 tends to slide out of the sliding hole 111. In order to reduce the probability of the blocking material 22 sliding out of the sliding hole 111, the stopper is arranged to protrude away from the side of the blocking material 22 away from the constraint member 21 in the second direction Y. In the first state, the distance between the constraint member 21 and the first limiting member 11 in the first direction X is the largest, and the stopper is in abutment with the first limiting member 11, so that at least part of the blocking material 22 is inside the sliding hole 111, thereby facilitating the transition from the first state to the second state.

[0069] In some embodiments, the blocking member 22 has a blocking surface in the second direction Y, and in the second state, the blocking surface and the side wall of the material passage 12 enclose a containing cavity, and the blocking surface is arranged in an inclined manner, and the size of the blocking member 22 in the second direction Y gradually decreases in a direction away from the first limiting member 11.

[0070] In the process of changing from the second state to the first state, the blocking member 22 tends to slide out of the sliding hole 111, and the material is inclined to the side of the second limiting member 14. Based on the above sliding tendency, the blocking surface is arranged in an inclined manner, which can reduce the degree of overturning of the material and make the blocking member 22 and the material gradually separate from each other.

[0071] In some embodiments, the first limiting member 11 is provided in plurality, and the plurality of first limiting members 11 are arranged at intervals in the first direction X, and the blocking structure 20 is also provided in plurality, and the blocking structure 20 is arranged in one-to-one correspondence with the first limiting member 11. The material transfer device further comprises a synchronization member 40, which extends in the first direction X and is connected with the plurality of blocking structures 20.

[0072] In order to improve the transfer efficiency, please refer to Figures 5 to 7 , a plurality of first limiting members 11 are arranged on the base 10, and a plurality of blocking structures 20 are arranged, and the blocking structure 20 is arranged in one-to-one correspondence with the first limiting member 11. A group of blocking structures 20 and first limiting members 11 can correspond to the transfer of one material. Specifically, a plurality of groups of blocking structures 20 and first limiting members 11 can be arranged at intervals in the first direction X, or a plurality of groups of blocking structures 20 and first limiting members 11 can be arranged at intervals in the second direction Y, or a plurality of groups of blocking structures 20 and first limiting members 11 can be arranged in a matrix distribution in the first direction X and the second direction Y to correspond to the interval and shape of the required placement position of the material. At the same time, in order to reduce the weight of the material transfer device, a through hole 15 is arranged in the plurality of groups of blocking structures 20 and first limiting members 11.

[0073] Further, in order to make a plurality of materials simultaneously separate from the material transfer device, a synchronization member 40 is arranged between the plurality of blocking structures 20 to connect the plurality of blocking structures 20 into one, so that the plurality of blocking structures 20 move synchronously relative to the base 10.

[0074] In some embodiments, the constraint member 21 protrudes the first limiting member 11 in the second direction Y, and the synchronization member 40 is connected with the plurality of constraint members 21 at the same time. In the second direction Y, the synchronization member 40 is arranged in abutment with the first limiting member 11. Through the above arrangement, on the basis of realizing that the synchronization member 40 is connected to the plurality of blocking structures 20, the abutment between the synchronization member 40 and the base 10 can also limit the relative positional relationship between the blocking structure 20 and the first limiting member 11 in the second direction Y.

[0075] In some embodiments, the base 10 further comprises a second limiting member 14, which is arranged in the first direction X away from the first limiting member 11, and the first limiting member 11 and the second limiting member 14 enclose the discharging channel 12 in the first direction X. In the second state, the surface of the blocking member 22 facing the second limiting member 14 is arranged away from the second limiting member 14 in the first direction X.

[0076] The two side walls of the first limiting member 11 and the second limiting member 14 facing each other in the first direction X form two side walls of the discharging channel 12, and the material is limited in the first direction X by the first limiting member 11 and the second limiting member 14 when the material is inside the discharging channel 12. At the same time, in the second state, the blocking member 22 bears the material in the second direction Y, and the material is limited by the blocking member 22, the first limiting member 11 and the second limiting member 14.

[0077] In the second state, the surface of the blocking member 22 facing the second limiting member 14 is arranged away from the second limiting member 14 in the first direction X. Through the above arrangement, the material can be separated by a shorter sliding distance under the premise of being made stable.

[0078] In some embodiments, the transmission assembly 30 comprises an input member 31, a transmission member 32 and an output member 33 connected to each other, the input member 31 is rotatably connected to the base 10, the output member 33 is fixedly connected to the constraint member 21, the input member 31 and the transmission assembly 30 are rotatably connected, the transmission member 32 and the output member 33 are rotatably connected, and the transmission assembly 30 forms a rigid transmission.

[0079] Specifically, the input member 31 has a fixed part 311 rotatably connected to the base 10, and a first movable part 312 and a second movable part 313 connected to the fixed part 311, the first movable part 312 and the second movable part 313 are connected by bending, the first movable part 312 is configured as a power input, and the second movable part 313 is rotatably connected to the transmission member 32. The power is input by the first movable part 312, the first movable part 312 drives the fixed part 311 and the second movable part 313 to rotate relative to the base 10, and at the same time, the input member 31 and the transmission member 32 are relatively rotated, and the transmission member 32 and the output member 33 are relatively rotated to drive the constraint member 21 to slide relative to the first limiting member 11.

[0080] Further, the base 10 is fixedly provided with a handle structure 60, which is arranged corresponding to the first movable part 312 to facilitate the technician to hold. In order to reduce the influence of high temperature on the handle structure 60 and the first movable part 312, the handle structure 60 and the first movable part 312 can be arranged as a wooden structure.

[0081] Further, the input member 31, the transmission member 32 and the output member 33 are rigid structures, and rigid transmission is formed inside the transmission assembly 30, i.e. the input member 31 and the constraint member 21 move synchronously. When the input member 31 starts to move, the constraint member 21 starts to move; when the input member 31 stops moving, the constraint member 21 stops moving.

[0082] In some embodiments, the material transfer device further comprises a reset member 50, one end of the reset member 50 is connected to the transmission assembly 30, and the other end is connected to the base 10, and the reset member 50 drives the material transfer device to be in the second state. Specifically, the reset member 50 is connected between the base 10 and the input member 31, when an external force acts, the input member 31 overcomes the force of the reset member 50, and drives the constraint member 21 to move, when the external force disappears, under the action of the reset member 50, the constraint member 21 is in the second position, i.e. the material transfer device is in the second state.

[0083] In one embodiment, the reset member 50 can be provided as a spring structure, the spring structure is connected between the base 10 and the input member 31, and the spring structure is used to reset the constraint member 21 by the elastic force. In another embodiment, the reset member 50 can be provided as a magnetic attraction structure, the magnetic attraction structure is connected between the base 10 and the input member 31, and the magnetic attraction structure is used to reset the constraint member 21 by the repulsive force or the attractive force.

[0084] In some embodiments, the constraint member 21 is rotatably arranged relative to the first limiting member 11 in the first direction X. In the first state, the constraint member 21 is arranged at an angle with the first limiting member 11, and the blocking member 22 and the discharging channel 12 do not overlap in the second direction Y. In the second state, the constraint member 21 is arranged in abutment with the first limiting member 11, and the blocking member 22 and the discharging channel 12 at least partially overlap in the second direction Y.

[0085] In the second state, the material is carried by the blocking member 22 in the second direction Y. In the process of changing from the second state to the first state, the constraint member 21 rotates in the first direction X, and the distance between the constraint member 21 and the first limiting member 11 in the first direction X gradually increases, and the projection area of the blocking member 22 and the discharging channel 12 in the second direction Y gradually decreases. In the process of rotating the constraint member 21 in the first direction X, the material is still inside the discharging channel 12 under the limiting action of the first limiting member 11, and when the change is made to the first state, the blocking member 22 and the discharging channel 12 do not overlap in the second direction Y, and the material has no supporting structure in the second direction Y, and the material is separated from the material transfer device.

[0086] Although the utility model has been described with reference to the preferred embodiments, various modifications can be made to it without departing from the scope of the utility model and equivalent replacements can be made to the components therein. In particular, the technical features mentioned in each embodiment can be combined in any manner as long as there is no structural conflict. The utility model is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
