Description

Technical Field

[0001] This application relates to the field of material handling mechanisms, and in particular to a steel sheet handling mechanism. Background Technology

[0002] In related technologies, the steel sheet picking mechanism is set inside the steel sheet flipping device. The suction head in the steel sheet picking mechanism is used to pick up steel sheets from the vibratory plate of the steel sheet flipping device. The steel sheet picking mechanism drives the suction head to move close to the vibratory plate through the driving component, and the movement stroke of the suction head is a fixed preset stroke. Multiple steel sheets are placed in the vibratory plate. The steel sheets are flipped to a preset orientation by the vibration of the vibratory plate. However, during the vibration of the vibratory plate, multiple steel sheets are prone to overlap. When the steel sheets overlap, the suction head is prone to crushing the lower steel sheet during the movement close to the vibratory plate, resulting in the steel sheet being damaged and scrapped, thereby reducing the stability of the steel sheet picking mechanism. Utility Model Content

[0003] In order to avoid the suction head from crushing the steel sheet and to improve the stability of the steel sheet picking mechanism, this application provides a steel sheet picking mechanism.

[0004] The steel sheet feeding mechanism provided in this application adopts the following technical solution:

[0005] A steel sheet picking mechanism includes: a connecting plate and a driving member, the driving member being disposed on the connecting plate; and a suction assembly including a connecting bracket, a suction head, and an elastic member, the connecting bracket being connected to the driving member, the connecting bracket defining a sliding channel, the suction head being slidably disposed within the sliding channel, with the end of the suction head extending out of the sliding channel, the elastic member being sleeved on the outer peripheral wall of the suction head, the elastic member being elastically deformable and disposed between the end of the suction head away from the connecting bracket and the connecting bracket, the suction head being adapted to engage with a steel sheet, the driving member being used to drive the connecting bracket to move the suction head closer to or away from the steel sheet, the steel sheet being adapted to drive the suction head to extend into the sliding channel, the elastic member being used to drive the suction head to move out of the sliding channel, and the suction head being connected to an air pump.

[0006] By adopting the above technical solution, when the suction head abuts against the overlapping steel sheet, the steel sheet drives the suction head into the sliding channel to prevent the suction head from crushing the steel sheet. After the suction head picks up the steel sheet, an elastic element drives the suction head to move out of the sliding channel to reset the suction head. Compared with the prior art, this method effectively prevents the suction head from crushing the steel sheet due to continued downward pressure when the steel sheets overlap, thereby improving the stability of the steel sheet picking mechanism and reducing the occurrence of steel sheet damage.

[0007] Preferably, the connecting bracket has a limiting part on the end wall near the suction head, the sliding channel passes through the limiting part, the outer peripheral wall of the end of the suction head away from the connecting bracket has a stop part, the stop part has a limiting groove near the end wall of the connecting bracket, one end of the elastic member is sleeved on the outside of the limiting part and limited to the limiting part, and the other end of the elastic member extends into the limiting groove and limited to the limiting groove.

[0008] By adopting the above technical solution, the elastic element is limited and matched with the limiting part and the limiting groove. When the suction head extends into or moves out of the sliding channel, the elastic element always maintains a stable relative position, thereby preventing the elastic element from sliding axially or shifting radially. This ensures that the elastic element continuously provides a stable elastic restoring force to the suction head, improving the reliability of the suction head reset.

[0009] Preferably, the end of the connecting bracket near the suction head is fitted with a first limiting member, the first limiting member having an avoidance hole opposite to the sliding channel, the suction head and the limiting member both passing through the avoidance hole, and the avoidance hole engaging with the elastic member for limiting.

[0010] By adopting the above technical solution, the clearance hole plays a positioning and limiting role for the elastic element, which can prevent the elastic element from being deflected or misaligned during the process of the suction head extending into or moving out of the sliding channel. This ensures that the suction head can maintain the axial alignment with the sliding channel after each adsorption and release action, thereby improving the structural coordination and stable operation of the steel sheet picking mechanism in the state of overlapping steel sheets.

[0011] Preferably, the outer peripheral wall of the end of the suction head that extends into the sliding channel is provided with an oblong hole, the oblong hole extending along the sliding direction of the suction head, and the outer peripheral wall of the connecting bracket is provided with a second limiting member, the second limiting member extending into the oblong hole and engaging with the oblong hole for limiting.

[0012] By adopting the above technical solution, when the steel sheet drives the suction head to extend into the sliding channel and the suction head extends into the sliding channel to the maximum stroke, the second limiting member abuts and limits the lower end wall of the waist-shaped hole, thereby preventing the suction head from extending too far into the sliding channel, preventing the steel sheet from colliding with the connecting bracket, and thus improving the working reliability of the steel sheet picking mechanism.

[0013] Preferably, the driving component includes a motor, a driving wheel, a driven wheel, and a transmission belt. The motor is mounted on the connecting plate. The driving wheel and the driven wheel are both pivotally mounted on the connecting plate. The motor is connected to the driving wheel. The transmission belt is driven to both the driving wheel and the driven wheel. The connecting bracket is connected to the transmission belt. The motor drives the driving wheel to rotate the transmission belt, so that the transmission belt drives the connecting bracket to move closer to or away from the steel plate.

[0014] By adopting the above technical solution, the motor drives the drive wheel to rotate, which in turn drives the transmission belt to rotate. The transmission belt pulls the connecting bracket to move the suction head closer to or away from the vibratory plate, so that the suction head can sequentially complete the entire material picking process of approaching the vibratory plate to pick up the steel sheet and moving away from the vibratory plate to complete the material picking process under the drive of the connecting bracket. This enables automatic gripping operation of the steel sheet in the flipped state, improving the action accuracy and reliability of the steel sheet picking mechanism in reciprocating operation.

[0015] Preferably, the connecting bracket includes a bracket body and a clamping part, the bracket body and the clamping part are connected and cooperate, and the transmission belt is clamped between the bracket body and the clamping part.

[0016] By adopting the above technical solution, the transmission belt is stably fixed by the bracket body and the clamping part together, so as to ensure that there will be no loosening or displacement between the connecting bracket and the transmission belt when the transmission belt drives the connecting bracket to move closer to or away from the steel sheet, thereby ensuring the accuracy of the transmission path of the connecting bracket and the stability of the steel sheet picking action.

[0017] Preferably, both the driving wheel and the driven wheel are configured as synchronous pulleys, and the transmission belt is configured as a synchronous belt.

[0018] By adopting the above technical solution, when the drive wheel rotates, the drive wheel can drive the transmission belt to move stably through synchronous meshing, so that the connecting bracket can move smoothly along the preset motion path. The connecting bracket drives the suction head to move closer to or away from the steel sheet, thereby achieving accurate picking of the steel sheet.

[0019] Preferably, there are multiple driving components and multiple suction components, and the multiple driving components and multiple suction components are spaced apart along the first direction of the connecting plate.

[0020] By adopting the above technical solution, multiple driving components drive the corresponding suction heads to move close to the vibratory plate. Multiple suction heads simultaneously adsorb multiple steel sheets in the vibratory plate, thereby achieving the technical effect of multiple suction heads picking up materials synchronously, which can improve the material picking efficiency of the steel sheet picking mechanism.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. When the suction head abuts against an overlapping steel sheet, the steel sheet drives the suction head into the sliding channel to prevent the suction head from crushing the steel sheet. After the suction head picks up the steel sheet, an elastic element drives the suction head out of the sliding channel to reset the suction head. Compared with the prior art, this method effectively prevents the suction head from crushing the steel sheet due to continued downward pressure when steel sheets overlap, thereby improving the stability of the steel sheet picking mechanism and reducing the occurrence of steel sheet damage.

[0023] 2. When the steel sheet drives the suction head to extend into the sliding channel and the suction head extends into the sliding channel to the maximum stroke, the second limiting member abuts and limits the lower end wall of the waist-shaped hole, thereby preventing the suction head from extending too far into the sliding channel, preventing the steel sheet from colliding with the connecting bracket, and thus improving the working reliability of the steel sheet picking mechanism.

[0024] 3. Multiple driving components drive the corresponding suction heads to move close to the vibratory plate. Multiple suction heads simultaneously adsorb multiple steel sheets in the vibratory plate, thereby achieving the technical effect of multiple suction heads picking up materials synchronously, which can improve the material picking efficiency of the steel sheet picking mechanism.

[0034] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0035] This application discloses a steel sheet feeding mechanism 100.

[0036] Reference Figures 1-3 The steel sheet feeding mechanism 100 according to the embodiments of this application includes: a connecting plate 1, a driving component 2, and a suction assembly 3.

[0037] The driving component 2 is mounted on the connecting plate 1. The suction assembly 3 includes a connecting bracket 31, a suction head 32, and an elastic member 33. The connecting bracket 31 is connected and cooperates with the driving component 2, defining a sliding channel 311. The suction head 32 is slidably disposed within the sliding channel 311, with its end extending out of the sliding channel 311. Specifically, along the height direction of the connecting plate 1, the upper end of the suction head 32 extends into the sliding channel 311, and the lower end of the suction head 32 extends out of the sliding channel 311. The elastic member 33... Three sleeves are installed on the outer peripheral wall of the suction head 32. An elastic element 33 is elastically deformable and disposed between the end of the suction head 32 away from the connecting bracket 31 and the connecting bracket 31. The suction head 32 is adapted to engage with the steel plate for abutment. The driving element 2 is used to drive the connecting bracket 31 to move the suction head 32 closer to or away from the steel plate. The steel plate is adapted to drive the suction head 32 to extend into the sliding channel 311. The elastic element 33 is used to drive the suction head 32 out of the sliding channel 311. The suction head 32 is connected to the air pump. The height direction of the connecting plate 1 can be indicated. Figure 2 The up and down directions in the middle.

[0038] In some specific embodiments, the sliding channel 311 extends along the height direction of the connecting plate 1, while in other specific embodiments, the sliding channel 311 passes through the connecting bracket 31 along the height direction of the connecting plate 1.

[0039] In some specific embodiments, the drive element 2 can be a cylinder.

[0040] In some specific embodiments, the elastic element 33 is preferably a spring.

[0041] Specifically, when the vibratory plate rotates the steel sheet inside the vibratory plate to a preset orientation, the drive unit 2 drives the connecting bracket 31 to move the suction head 32 closer to the vibratory plate. The suction head 32 extends into the vibratory plate and abuts against the steel sheet. Then, the air pump draws air from the suction head 32 so that the suction head 32 can adsorb the steel sheet. The drive unit 2 drives the connecting bracket 31 to move the suction head 32 away from the vibratory plate to complete the steel sheet picking action.

[0042] Furthermore, when the steel sheets in the vibratory feeder overlap and the suction head 32 abuts against the overlapping steel sheets, the driving member 2 drives the suction head 32 to move closer to the steel sheets. The steel sheets drive the suction head 32 to extend into the sliding channel 311, thereby preventing the suction head 32 from crushing the steel sheets. After the suction head 32 has finished adsorbing the steel sheets, the driving member 2 drives the suction head 32 to move away from the vibratory feeder, and the elastic member 33 drives the suction head 32 to move out of the sliding channel 311 so that the suction head 32 can be reset.

[0043] Therefore, when the suction head 32 comes into contact with the overlapping steel sheet, the steel sheet drives the suction head 32 to extend into the sliding channel 311 to prevent the suction head 32 from crushing the steel sheet. After the suction head 32 picks up the steel sheet, the elastic element 33 drives the suction head 32 to move out of the sliding channel 311 so that the suction head 32 returns to its original position. Compared with the prior art, when the steel sheets overlap, the suction head 32 can be effectively prevented from crushing the steel sheet due to continued downward pressure, thereby improving the operational stability of the steel sheet picking mechanism 100 and reducing the occurrence of steel sheet damage.

[0044] Reference Figure 2 and Figure 3 In some embodiments of this application, the end wall of the connecting bracket 31 near the suction head 32 is provided with a limiting part 312, the sliding channel 311 passes through the limiting part 312, the outer peripheral wall of the end of the suction head 32 away from the connecting bracket 31 is provided with a stop part 321, the stop part 321 is provided with a limiting groove 322 near the end wall of the connecting bracket 31, one end of the elastic member 33 is sleeved on the outside of the limiting part 312 and is limited and engaged with the limiting part 312, and the other end of the elastic member 33 extends into the limiting groove 322 and is limited and engaged with the limiting groove 322. Specifically, along the height direction of the connecting plate 1, the upper end of the elastic member 33 is sleeved on the outside of the limiting part 312, and the lower end of the elastic member 33 extends into the limiting groove 322.

[0045] In some specific embodiments, the limiting groove 322 can be configured as an annular shape.

[0046] With the elastic element 33 in a limiting fit with both the limiting part 312 and the limiting groove 322, the elastic element 33 always maintains a stable relative position when the suction head 32 extends into or moves out of the sliding channel 311. This prevents the elastic element 33 from sliding axially or shifting radially, thereby ensuring that the elastic element 33 continuously provides a stable elastic restoring force to the suction head 32 and improving the reliability of the suction head 32's reset.

[0047] Reference Figure 2 and Figure 3In some embodiments of this application, a first limiting member 313 is sleeved on the end of the connecting bracket 31 near the suction head 32. The first limiting member 313 is provided with a clearance hole 314, and the clearance hole 314 is constructed as a through hole. The clearance hole 314 is opposite to the sliding channel 311. Along the height direction of the connecting plate 1, the sliding channel 311 is located above the clearance hole 314, and the stop part 321 is located on the side of the clearance hole 314 away from the sliding channel 311. The suction head 32 and the limiting member both pass through the clearance hole 314. Specifically, the end of the suction head 32 away from the sliding channel 311 passes through the clearance hole 314, and the clearance hole 314 is limited and engaged with the elastic member 33.

[0048] The clearance hole 314 plays a positioning and limiting role for the elastic element 33, which can prevent the elastic element 33 from being deflected or misaligned during the process of the suction head 32 extending into or moving out of the sliding channel 311. This ensures that the suction head 32 can maintain the axial alignment with the sliding channel 311 after each adsorption and release action, thereby improving the structural coordination and stable operation of the steel sheet picking mechanism 100 in the state of overlapping steel sheets.

[0049] Reference Figure 2 and Figure 3 In some embodiments of this application, the outer peripheral wall of the end of the suction head 32 that extends into the sliding channel 311 is provided with a waist-shaped hole 323. The waist-shaped hole 323 extends along the sliding direction of the suction head 32. Specifically, the waist-shaped hole 323 extends along the height direction of the connecting plate 1. The outer peripheral wall of the connecting bracket 31 is provided with a second limiting member 315. The second limiting member 315 extends into the waist-shaped hole 323 and is limited and cooperates with the waist-shaped hole 323.

[0050] Specifically, when the steel sheet drives the suction head 32 to extend into the sliding channel 311 and the suction head 32 extends into the sliding channel 311 to the maximum stroke, the second limiting member 315 abuts and limits the lower end wall of the waist-shaped hole 323, thereby preventing the suction head 32 from extending excessively into the sliding channel 311, preventing the steel sheet from colliding with the connecting bracket 31, and thus improving the working reliability of the steel sheet picking mechanism 100.

[0051] Furthermore, when the elastic member 33 drives the suction head 32 to move out of the sliding channel 311 to the maximum stroke, the second limiting member 315 abuts and limits the upper end wall of the waist-shaped hole 323, thereby preventing the suction head 32 from disengaging from the sliding channel 311 and thus improving the working reliability of the steel sheet picking mechanism 100.

[0052] Reference Figure 1 , Figure 2 and Figure 4In some embodiments of this application, the driving component 2 includes a motor 21, a driving wheel 22, a driven wheel 23, and a transmission belt 24. The motor 21 is disposed on the connecting plate 1. The driving wheel 22 and the driven wheel 23 are both pivotally mounted on the connecting plate 1. The motor 21 is connected and cooperates with the driving wheel 22. The transmission belt 24 is wrapped around the outer peripheral wall of the driving wheel 22 and the outer peripheral wall of the driven wheel 23. The transmission belt 24 is connected and driven by both the driving wheel 22 and the driven wheel 23. The connecting bracket 31 is connected and cooperates with the transmission belt 24. The motor 21 is used to drive the driving wheel 22 to drive the transmission belt 24 to rotate, so that the transmission belt 24 drives the connecting bracket 31 to move closer to or away from the steel plate.

[0053] Furthermore, when the motor 21 drives the transmission belt 24 to rotate, the transmission belt 24 drives the driven wheel 23 to rotate.

[0054] The motor 21 drives the drive wheel 22 to rotate, which in turn drives the transmission belt 24 to rotate. The transmission belt 24 pulls the connecting bracket 31 to move the suction head 32 closer to or away from the vibrating plate, so that the suction head 32 can sequentially complete the entire material picking process under the drive of the connecting bracket 31, moving closer to the vibrating plate to pick up the steel sheet and moving away from the vibrating plate to complete the material picking. This enables automatic gripping operation of the steel sheet in the flipped state, improving the action accuracy and reliability of the steel sheet picking mechanism 100 in reciprocating operation.

[0055] Reference Figure 4 In some embodiments of this application, the connecting bracket 31 includes a bracket body 316 and a clamping part 317, the bracket body 316 and the clamping part 317 are connected and cooperated, and the transmission belt 24 is clamped between the bracket body 316 and the clamping part 317.

[0056] The transmission belt 24 is clamped between the bracket body 316 and the clamping part 317. The bracket body 316 and the clamping part 317 work together to stably fix the transmission belt 24, so as to ensure that the transmission belt 24 will not loosen or shift between the connecting bracket 31 and the transmission belt 24 when the transmission belt 24 drives the connecting bracket 31 to move closer to or away from the steel sheet. This ensures the accuracy of the transmission path of the connecting bracket 31 and the stability of the steel sheet picking action.

[0057] In some embodiments of this application, both the driving wheel 22 and the driven wheel 23 are configured as synchronous pulleys, and the transmission belt 24 is configured as a synchronous belt.

[0058] When the drive wheel 22 rotates, it can drive the transmission belt 24 to move stably through synchronous meshing, so that the connecting bracket 31 can move smoothly along the preset movement path. The connecting bracket 31 drives the suction head 32 to move closer to or away from the steel sheet, thereby achieving accurate picking of the steel sheet.

[0059] Reference Figure 1In some embodiments of this application, there are multiple driving components 2 and multiple suction components 3, and the multiple driving components 2 and multiple suction components 3 are all spaced apart along the first direction of the connecting plate 1. The first direction of the connecting plate 1 can refer to... Figure 1 The left and right directions in the middle.

[0060] Multiple driving components 2 drive the corresponding suction heads 32 to move close to the vibratory plate. The multiple suction heads 32 simultaneously adsorb multiple steel sheets in the vibratory plate, thereby achieving the technical effect of multiple suction heads 32 picking up materials synchronously, which can improve the picking efficiency of the steel sheet picking mechanism 100.

[0061] Furthermore, when some steel sheets overlap, the overlapping steel sheets drive the corresponding suction head 32 to extend into the sliding channel 311, thereby avoiding the problem of the steel sheet being crushed due to the suction head 32 continuing to press down. This enables the steel sheet picking mechanism 100 to pick up steel sheets from multiple stations in parallel and stably.

[0062] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
