[0004] However, for small-sized circuit boards, after completing the anti-oxidation operation according to the conventional receiving steps, they are moved to the receiving position. Since the receiving area is much larger than that of small-sized circuit boards, after a row of small-sized circuit boards is fully loaded at the receiving area, there are still many empty positions in the receiving area. If the operator is required to empty each full row, it will lead to frequent operations by the operator and the receiving area cannot be fully utilized.

[0037] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. The described implementation is a part of the implementation of the utility model, not all of the implementations.

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

[0039] Embodiment 1:

[0040] Please refer to the attached Figure 1-3The large-capacity material receiving structure of the utility model includes a shell 1, a material placing mechanism 2 and a material separating mechanism 3. The material placing mechanism 2 and the material separating mechanism 3 are both connected to the shell 1, and the material separating mechanism 3 is arranged at the upper end of the material placing mechanism 2; wherein the material placing mechanism 2 includes a driving body 21 and a conveyor belt 22, and the driving body 21 is drivingly connected to the conveyor belt 22; the material separating mechanism 3 includes a plurality of material separating components 31, a storage plate component 32 and a shifting plate component 33, and the shifting plate component 33 is connected to the storage plate component 32 and arranged in parallel, and the material separating component 31 moves between the storage plate component 32 and the shifting plate component 33, and the shifting plate component 33 is arranged corresponding to the material placing mechanism 2, and the storage plate component 32 is arranged at the material input end of the material placing mechanism 2. wherein the material input end of the material placing mechanism 2 is the end where the circuit board enters the material receiving structure. The driving body 21 can be realized by an existing motor. preferably, three material separating components 31 are arranged.

[0041] The placing mechanism 2 is used to place the circuit boards that have completed the anti-oxidation operation. The material separation component 31 is used to separate each row of circuit boards. The board storage component 32 is used to place unused partition components. The board moving component 33 is used to move the material separation component 31 to the transmission belt at the corresponding position.

[0042] The operation process of the material receiving structure in this embodiment is as follows: when the anti-oxidation operation is performed on the small-sized circuit board, the material placing mechanism 2 and the material separation mechanism 3 start to operate. First, the material separation mechanism 3 is started, the material separation component 31 is moved out of the board storage component 32, and moves along the plate shifting component 33 to the corresponding position of the conveyor belt 22 and then stops, wherein the moving distance of the material separation component 31 is flexibly adjusted according to the size of the circuit board, waiting for the circuit board to be loaded between the conveyor belt 22 and the material separation component 31 until the circuit board is fully loaded. After the first row of loaded circuit boards is completed, the material separation mechanism 3 is started again, the material separation component 31 is moved out of the board storage component 32, and when the material separation component 31 moves to the junction of the plate shifting component 33 and the board storage component 32, the plate shifting component 33 and the driving body 21 move synchronously, so that the partition component and the circuit board located on the conveyor belt 22 are synchronously moved to a position away from the board storage component 32, thereby providing storage space for the loading of the next circuit board, and then waiting for the circuit board to be loaded between the conveyor belt 22 and the material separation component 31 again until the circuit board is fully loaded. The above operation is repeated until all the space on the conveyor belt 22 is used up to ensure that the conveyor belt 22 is fully loaded with circuit boards. When the operator clears the conveyor belt 22 full of circuit boards, the plate moving component 33 pushes the material separation component 31 back to the board storage component 32. The board storage component 32 starts after sensing the material separation component 31, and stops after retracting the material separation component 31. The plate moving component 33 continues to rotate and successively sends multiple equidistant partition components back to the board storage component 32, and the board storage component 32 stores the partition components 31 in turn. It can be understood that the operation process of the material collection structure can be realized by using the existing PLC program and sensor to cooperate with control.

[0043] Through the arrangement of the above-mentioned structure, the material placement mechanism 2 is adopted to fully utilize the material receiving area, that is, the conveyor belt 22 in the idle area is moved to the discharging end, so that the idle area is used to place small-sized circuit boards that have completed the antioxidant operation, and each row of circuit boards is separated by the material separation mechanism 3 to ensure the neatness of the material receiving. This arrangement can effectively increase the material receiving capacity, improve the utilization rate of the material receiving area, and greatly reduce the number of operations by the operator.

[0044] For details, please refer to the attached Figure 4 The material separation component 31 includes a first partition plate 311, a first connector 312 and a first gear 313. The first connector 312 is symmetrically connected to both sides of the first partition plate 311, and the other end of the first connector 312 is movably connected to the first gear 313. The first partition plate 311 serves to separate the circuit boards, ensuring that the circuit boards placed in each row are neat and clear, and not messy. The first gear 313 is used to drive the first partition plate 311 to move.

[0045] Please refer to the attached Figure 5 The shift plate component 33 includes a first toothed belt 331, a second toothed belt 332, a first motor 333 that drives the first toothed belt 331 to rotate, and a second motor 334 that drives the second toothed belt 332 to rotate; the first toothed belt 331 and the second toothed belt 332 are symmetrically arranged with the first gear 313 as the center, and the first toothed belt 331 and the second toothed belt 332 are both meshed and connected with the first gear 313.

[0046] Please refer to the attached Figure 6 and Figure 7 The plate storage component 32 includes a plate storage cavity 321, a third toothed belt 322 arranged in parallel with the first toothed belt 331, a fourth toothed belt 323 arranged in parallel with the second toothed belt 332, a third motor 324 driving the third toothed belt 322 to rotate, and a fourth motor 325 driving the fourth toothed belt 323 to rotate; wherein the third toothed belt 322 and the fourth toothed belt 323 are symmetrically arranged with the first gear 313 as the center, and the third toothed belt 322 and the fourth toothed belt 323 are both meshed and connected with the first gear 313. The lower end of the plate storage cavity 321 is arranged flush with the conveyor belt 22; the plate storage cavity 321 is formed by the shell 1 being recessed in the direction away from the conveyor belt 22. wherein the plate storage cavity 321 is used to place a plurality of material separation components 31.

[0047] It can be understood that the moving action of the material separation component 31 on the storage plate component 32 is: start the third motor 324 and the fourth motor 325, drive the third toothed belt 322 and the fourth toothed belt 323 to move, thereby driving the first gear 313 to translate, and the material separation component 31 enters and exits the storage plate component 32. The moving action of the material separation component 31 on the transfer plate component 33 is: start the first motor 333 and the second motor 334, drive the first toothed belt 331 and the second toothed belt 332 to move, thereby driving the first gear 313 to translate, and the material separation component 31 moves on the material separation component 31. By separately setting the storage plate component 32 and the material separation component 31, the storage plate component 32 and the material separation component 31 operate independently to ensure the realization of the function. And by setting the lower end of the storage plate cavity 321 to be flush with the conveyor belt 22, the smooth movement of the first partition 311 is achieved, which facilitates the first partition 311 to move between the storage plate component 32 and the transfer plate component 33. The overall structural design is ingenious. For large-sized circuit boards, there is no need to use the material receiving structure. It is only necessary to place the first partition plate 311 in the storage cavity. It is compact and practical, and the action process has a strong rhythmicity.

[0048] Embodiment 2:

[0049] The difference between this embodiment and embodiment 1 is that this embodiment further optimizes the structure of the material receiving structure of the utility model.

[0050] See also Figure 8 to Figure 10 The material separation component 31 of this embodiment includes a second partition plate 314, a second connecting body 315 and a second gear 316. The second connecting body 315 is provided with a first end 3151 and a second end 3152 opposite to each other. The first end 3151 is slidably connected to the second partition plate 314, and the second end 3152 is movably connected to the second gear 316. The second partition plate 314 is provided with a sliding groove 3141 corresponding to the second connecting body 315. The second end 3152 is provided with a moving groove 3153 and a pulley 3154 symmetrically arranged in the moving groove 3153; the pulley 3154 is embedded in the sliding groove 3141.

[0051] See also Figure 11-12 The material placement mechanism 2 also includes a material placement rack 23 and a lifting cylinder 24 . The lifting cylinder 24 is connected to the material placement rack 23 for driving and lifting. The driving body 21 is fixedly connected to the material placement rack 23 . The conveyor belt 22 is arranged in the material placement rack 23 .

[0052] The coordinated action of the material separation component 31 and the material placement component in this embodiment can utilize the upper and lower spaces of the material placement component, thereby further increasing the placement capacity of the circuit board, and can also ensure the neatness of the placement of multiple rows of circuit boards. In addition, during the material collection process of the material placement mechanism 2, the plane of the conveyor belt 22 can be close to the plane of the incoming material, so that the stability of the material collection process is improved, that is, each time a circuit board is received, the lifting cylinder 24 drives the material placement rack 23 to drop a certain distance, thereby maintaining the plane of the incoming material and the plane of the material placement within a range, ensuring that the collected material does not need to fall from a high place, and improving the stability of the material collection.

[0053] The specific action is as follows: during the up and down movement of the material placing mechanism 2, the second partition 314 can move up and down with the lifting and lowering of the conveyor belt 22, that is, the lower end of the second partition 314 is always in close contact with the conveyor belt 22. When the lifting cylinder 24 drives the material placing rack 23 to move downward, the conveyor belt 22 also moves downward, and the second partition 314 also moves downward due to the downward gravity. By setting the sliding groove 3141, the lifting and lowering of the second partition 314 is guided to ensure the verticality of the lifting and lowering direction of the second partition 314. By setting the pulley 3154, the lifting and lowering of the second partition 314 is prevented from being stuck, and the lifting and lowering of the second partition 314 is ensured to be smooth.

[0054] In addition, when the second partition board 314 needs to enter and exit the storage chamber, it is only necessary to raise and lower the conveyor belt 22 to be flush with the bottom of the storage board component 32. Each action can be realized by the existing PLC program control.
