[0002] In the workpiece blanking process of the zinc alloy production line, after the zinc alloy block is formed through casting, cooling and other processes, it needs to be transferred to the blanking link through the conveyor for centralized stacking, so as to prepare for subsequent warehousing, transportation or deep processing. When the workpiece is blanked onto the conveyor, the workpiece may be turned over, so the workpiece needs to be turned over for easy handling. However, during the transportation of the workpiece on the conveyor, due to the vibration of the conveyor belt or the deviation of the initial feeding position of the workpiece, the workpiece is easy to collide and fall off from the conveyor, and it may also be unable to cooperate with the turnover mechanism due to the deviation of the alignment, affecting the subsequent handling and stacking.

The adaptive slope of the inner wall of the turnover mold can fit the outer contour of the workpiece, providing stable support for subsequent workpiece turnover. If the workpiece has been turned over, it cannot enter the turnover mold. The first sensor and the second sensor detect the positions of the workpieces on both sides of the turnover mechanism, and cooperate with the intercepting member to control the transmission rhythm of the workpieces. After the workpieces are intercepted by the intercepting member, the edges of the workpieces will gradually be flush with the intercepting member under the continuous driving of the conveying belt, which can reduce the positional deviation of the workpieces.

On the one hand, the symmetrical turnover molds can simultaneously apply force to the workpiece from both sides, which can more evenly fit the outer contour of the workpiece compared to a single-sided turnover mechanism, avoiding workpiece turnover deviation or deformation caused by single-sided force, and improving the stability and accuracy of workpiece turnover. On the other hand, the synchronous rotation of the two turnover molds can enhance the driving force of the turnover action, especially for heavy or irregular zinc alloy workpieces, which can effectively overcome the inertia of the workpiece and ensure smooth turnover.

When it is necessary to turn over zinc alloy workpieces of different thicknesses and heights, the lifting power member can drive the lifting platform to move the turnover mold up and down, flexibly adjusting the distance between the turnover mold and the conveyor belt.

[0012] Optionally, the positioning mechanism further comprises two second positioning assemblies, the two second positioning assemblies are arranged on the two sides of the discharge end of the conveyor, a second positioning plate is arranged on the second positioning assembly, the second positioning plate is located above the conveying belt, and the first positioning assembly drives the first positioning plate to be close to or away from the conveyor.

[0013] By adopting the technical scheme, the double second positioning assemblies and the second positioning plates are arranged on the two sides of the discharge end of the conveyor, the workpiece to be clamped after being turned over can be positioned again, the workpiece slightly deviated after being turned over can be returned to the best clamping position of the clamping jaw assembly, the mechanical arm can accurately align the workpiece when driving the clamping jaw assembly, the clamping failure or the workpiece falling off during clamping due to the deviation of the workpiece is avoided, and the stability of the clamping and transferring of the carrying mechanism is improved. Meanwhile, the uniformly positioned workpiece can also reduce the misalignment friction between the clamping jaw assembly and the workpiece, and reduce the risk of scratching the surface of the workpiece.

[0014] Optionally, the clamping jaw assembly comprises a mounting plate and two clamping piece groups symmetrically arranged, the clamping piece group is rotationally connected with the mounting plate, a clamping power element is arranged on the mounting plate, and an output end of the clamping power element is connected with a rotating shaft of the clamping piece group.

[0017] By adopting the technical scheme, the transverse assembly and the longitudinal assembly realize the ascending and descending of the pushing plate and the changing of the distance between the two pushing plates, so that after the zinc alloy blocks are stacked at the unloading point, the pushing plate clamps and stacks the zinc alloy block stack from the two sides of the zinc alloy block, and the subsequent carrying is facilitated.

[0021] By adopting the above technical scheme, when the workpiece falls into the receiving frame from the upstream process, it first contacts the buffer plate, the buffer plate is compressed by the top rod after being stressed, the deformation of the elastic element can absorb the impact force of the workpiece falling, the surface indentation, corner knocking and other damages caused by the direct impact of the workpiece on the receiving frame or the conveying belt are avoided, especially for the zinc alloy workpiece with large weight or high brittleness, the workpiece loss rate at the feeding end can be significantly reduced, and the quality qualified rate of the workpiece after discharging is improved.

[0022] The application also provides a working method of the automatic discharging device of the zinc alloy production line, adopts the automatic discharging device of the zinc alloy production line as described above, and the working method comprises the following steps: the workpiece falls into the conveying belt from the feeding end, the conveying belt drives the workpiece to move from the feeding end to the discharging end of the conveying machine, the workpiece moves to the intercepting element and passes through the intercepting element, the overturning power element drives the overturning die to be close to the conveying machine above the conveying belt; the workpiece with the front face upward passes through the first sensor and enters the overturning die, the workpiece is overturned by 180° by the overturning mechanism, the overturning power element drives the overturning die to be away from the conveying machine, the workpiece falls into the conveying belt again and starts to move, the intercepting element no longer blocks the next workpiece after the workpiece passes through the second sensor, and the workpiece is clamped and transferred by the carrying mechanism after moving to the discharging end of the conveying machine; the workpiece with the back face upward contacts the inclined surface of the overturning die and is blocked, the workpiece blocks the first sensor so that the first sensor continuously detects the signal, the overturning power element drives the overturning die to be away from the conveying machine, and the workpiece directly moves to the discharging end through the overturning mechanism and the second sensor.

[0023] In summary, the application has at least one of the following beneficial effects: 1. The flipping mechanism drives the rotation and displacement of the flipping mold through the flipping power component. Combined with the signal feedback from the first sensor, it can automatically complete the identification and flipping of the front and back of the workpiece. The whole process does not require manual judgment of the front and back of the workpiece. It relies entirely on the collaboration of the flipping mechanism and the sensor to complete the automated screening and flipping, avoiding errors caused by manual operation, ensuring that all workpieces entering the subsequent process have the same posture, and improving the automation accuracy of the material feeding process.

[0024] 2. The first positioning component of the positioning mechanism drives the first positioning plate to adjust the spacing, which can restrict the workpiece to the preset path of the conveyor belt before it reaches the interceptor, preventing the workpiece from being unable to accurately enter the flipping mold due to conveying deviation. The interceptor controls the passage rhythm of the workpiece through a hinged structure. In conjunction with the signal linkage of the first and second sensors, it blocks the next workpiece from entering before a single workpiece completes its flipping or passes through the flipping mechanism, preventing congestion in the flipping area. The coordinated action of the mechanisms on the conveyor ensures that the workpieces remain in an orderly state during the conveying process, reducing workpiece position deviation and problems such as jamming and falling during the conveying process, and improving the continuity of the unloading process.

[0025] 3. The buffer plate in the middle of the receiving rack is connected to the elastic element through the top rod. When the workpiece falls into the receiving rack from the upstream process, it first contacts the buffer plate. After the buffer plate is subjected to force, it compresses the elastic element. The deformation of the elastic element can effectively absorb the impact force of the workpiece falling, avoiding the workpiece from directly hitting the receiving rack or the conveyor belt. At the same time, the receiving rack can rotate relative to the conveyor frame, changing the height of the receiving rack to reduce the falling height of the workpiece from the feeding end into the conveyor belt, further reducing collisions and reducing the workpiece loss rate.
