Plate conveying and positioning device

Abstract

The utility model belongs to the field of plate machining, and particularly relates to a plate conveying and positioning device which is characterized in that a plurality of avoiding holes are formed in a plate positioning area on a supporting plate, and a conveying mechanism is driven by a lifting mechanism located below the supporting plate to move up and down so as to be close to or away from the supporting plate; the plate can enter the position above the plate positioning area under the driving of the rolling wheels on the conveying shaft, and due to the fact that the height of the first clamping blocks protruding out of the upper surface of the supporting plate is smaller than the height of the rolling wheels protruding out of the upper surface of the supporting plate in the conveying state, the first clamping blocks cannot hinder conveying of the plate on the rolling wheels; after a plate enters the position above the plate positioning area, the lifting mechanism drives the rolling wheels on the conveying shafts to retreat from the avoiding holes, so that the plate falls into the plate positioning area, and then the plate can be clamped and positioned in the first direction and the second direction through the first positioning assembly and the second positioning assembly correspondingly.

The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0037] It should also be noted that, in the embodiments of the present application, the same figure mark is used to represent the same component or the same part. For the same parts in the embodiments of the present application, the figure may only mark one of the parts or components as an example. It should be understood that the figure mark also applies to other identical parts or components.

[0038] The embodiment of the present application provides a plate conveying and positioning device, such as Figure 1-Figure 4 As shown, the plate conveying and positioning device includes a support plate 10, a lifting mechanism 20, a conveying mechanism 30, a first positioning component and a second positioning component.

[0039] The upper surface of the support plate 10 is provided with a plate positioning area 101, the lifting mechanism 20 is located below the support plate 10, the conveying mechanism 30 includes a plurality of conveying shafts 31, a plurality of rollers 32 and a driving assembly 33 for driving each conveying shaft 31 to rotate synchronously, the plurality of conveying shafts 31 are arranged on the lifting mechanism 20 in parallel and at intervals in a first direction (the direction where the X axis is located in the figure), and each conveying shaft 31 is provided with a plurality of rollers 32; the plate positioning area 101 is provided with a plurality of avoidance holes 1011 corresponding to each roller 32 in the vertical direction, and under the action of the lifting mechanism 20, the roller 32 can be in a conveying state (such as when the roller 32 is in a state of extending out of the avoidance hole 1011) Figure 1 The first positioning assembly is arranged on the support plate 10, and the first positioning assembly has two first clamping blocks 41 that can be relatively opened and closed in the first direction. The two first clamping blocks 41 are used to clamp and position the plate entering the plate positioning area 101 in the first direction; the first clamping blocks 41 are convexly arranged at a height ( Figure 3 The height of the roller 32 protruding from the upper surface of the support plate 10 in the conveying state (indicated by h) is less than the height of the roller 32 protruding from the upper surface of the support plate 10 in the conveying state ( Figure 3 The second positioning assembly is disposed on the support plate 10, and has two second clamping blocks 51 that can be relatively opened and closed in a second direction (the direction where the Y axis is located in the figure) perpendicular to the first direction. The two second clamping blocks 51 are used to clamp and position the plate entering the plate positioning area 101 in the second direction.

[0040] It can be understood that the size of the plate suitable for the plate conveying and positioning device is smaller than the size of the plate positioning area 101, so that the plate falling into the plate positioning area 101 can be clamped and positioned by the first positioning component and the second positioning component in the first direction and the second direction respectively.

[0041] In the embodiment of the present application, the sheet conveying and positioning device is provided with a plurality of avoidance holes 1011 in the sheet positioning area 101 on the support plate 10, and uses the lifting mechanism 20 located below the support plate 10 to drive the conveying mechanism 30 to move up and down to approach or move away from the support plate 10. When the roller 32 is in the conveying state (that is, the roller 32 on the conveying shaft 31 in the conveying mechanism 30 extends out of the avoidance hole 1011 on the sheet positioning area 101), the sheet can be driven by the roller 32 on the conveying shaft 31 to enter the upper part of the sheet positioning area 101. Due to the first clamp The height of the holding block 41 protruding from the upper surface of the support plate 10 is less than the height of the roller 32 protruding from the upper surface of the support plate 10 when the roller 32 is in the conveying state. Therefore, the first clamping block 41 will not hinder the conveying of the plate on the roller 32; when the plate enters above the plate positioning area 101, the lifting mechanism 20 drives the roller 32 on the conveying shaft 31 to withdraw from the avoidance hole 1011 (that is, switch to a hidden state), so that the plate falls into the plate positioning area 101, and then the first positioning component and the second positioning component can respectively clamp and position the plate in the first direction and the second direction.

[0042] In one embodiment, if Figure 1-Figure 2 As shown, the plate positioning area 101 is rectangular. Since the plate is usually rectangular, the plate positioning area 101 is designed to be rectangular, which can better adapt to the shape of the plate.

[0043] In one embodiment, if Figure 3 As shown, the lifting mechanism 20 includes a base 21, a lifting drive member 22 and a lifting frame 23. The base 21 is located below the support plate 10. The lifting drive member 22 is arranged on the base 21. The lifting frame 23 is arranged on the lifting drive member 22 and can move up and down under the action of the lifting drive member 22 to approach or move away from the support plate 10. A plurality of conveying shafts 31 are rotatably arranged on the lifting frame 23.

[0044] In one implementation, the lifting drive member 22 includes a cylinder, the cylinder body of the cylinder is fixed on the base 21, the piston rod of the cylinder is vertically upward, and the lifting frame 23 is arranged on the piston rod of the cylinder. The lifting frame 23 is driven up and down by the cylinder to switch the roller 32 between the conveying state of extending out of the avoidance hole 1011 and the hidden state of withdrawing from the avoidance hole 1011.

[0045] It is understandable that in other implementations, the lifting drive member 22 may also be a linear drive member such as an electric cylinder, a flashlight push rod, or an oil cylinder.

[0046] In a specific embodiment, please continue to refer to Figure 3 The lifting mechanism 20 further includes a guide assembly 24 , which includes a guide rod 241 vertically disposed on the base 21 and a sliding sleeve 242 disposed on the lifting frame 23 and slidably connected to the guide rod 241 .

[0047] By arranging a guide assembly 24 composed of a guide rod 241 and a sliding sleeve 242 between the base 21 and the lifting frame 23, the stability of the lifting frame 23 during the lifting movement is improved.

[0048] Furthermore, a plurality of guide rods 241 may be provided, and a sliding sleeve 242 is slidably sleeved on each guide rod 241, and each sliding sleeve 242 is connected to the lifting frame 23. Specifically, four guide rods 241 are provided, and the four guide rods 241 are arranged in a matrix on the base 21, and the lifting drive member 22 is arranged at the center of a rectangle formed by the four guide rods 241. With this design, the lifting frame 23 and the conveying mechanism 30 located on the lifting frame 23 are uniformly stressed as a whole during the lifting process.

[0049] In a specific embodiment, the driving assembly 33 includes a rotating driving member, a worm and a plurality of turbines. The worm is rotatably arranged on the lifting frame 23 and extends along the first direction. The plurality of turbines are respectively arranged one by one on the plurality of conveying shafts 31, and the plurality of turbines are all engaged with the worm. The rotating driving member is arranged on the lifting frame 23 and is drivingly connected to the worm.

[0050] The rotating drive member may be a motor, the output shaft of which is directly or indirectly (through belt drive, chain drive, gear drive, etc.) connected to one end of the worm to drive the worm to rotate, and then drive the conveying shafts 31 to rotate synchronously through the turbine.

[0051] It is conceivable that in other implementations, the drive assembly 33 can also be implemented in other ways. For example, the drive assembly 33 includes multiple synchronous pulleys, a synchronous belt and a motor. The multiple synchronous pulleys are respectively arranged on multiple conveying shafts 31 in a one-to-one manner. The synchronous belt connects the synchronous pulleys. The motor drives one of the conveying shafts 31 to rotate, and drives the remaining conveying shafts 31 to rotate synchronously with the system's rotation direction through the synchronous belt.

[0052] In one embodiment, if Figure 1-Figure 3As shown, the first positioning assembly includes two first linear modules 42, and a first accommodating groove 1012 extending along the first direction is respectively provided at the opposite ends of the plate positioning area 101 in the first direction. The two first linear modules 42 are respectively embedded in the two first accommodating grooves 1012, and the two first clamping blocks 41 are respectively provided on the two first linear modules 42 and protrude from the upper surface of the support plate 10. The two first clamping blocks 41 can make relative opening and closing movements in the first direction under the drive of the two first linear modules 42.

[0053] Specifically, the first linear module 42 can be a ball screw type linear module, a synchronous belt type linear module, or even a linear drive component such as an electric push rod.

[0054] Preferably, in order to improve the centering positioning of the plate falling into the plate positioning area 101 in the first direction, two groups of first positioning components are provided, and accordingly, four first accommodating grooves 1012 are provided. The four first accommodating grooves 1012 are arranged in pairs at the opposite ends of the plate positioning area 101 in the first direction, and the two groups of first positioning components are arranged at intervals in the second direction.

[0055] In one embodiment, if Figure 1-Figure 2 and Figure 5 As shown, the second positioning assembly includes two second linear modules 52, and a second accommodating groove 1013 extending along the second direction is respectively provided at the opposite ends of the plate positioning area 101 in the second direction. The two second linear modules 52 are respectively embedded in the two second accommodating grooves 1013, and the two second clamping blocks 51 are respectively arranged on the two second linear modules 52 and protrude from the upper surface of the support plate 10. The two second clamping blocks 51 can make relative opening and closing movements in the second direction under the drive of the two second linear modules 52.

[0056] Specifically, the second linear module 52 may also be a ball screw type linear module, a synchronous belt type linear module, or even a linear drive component such as an electric push rod.

[0057] Preferably, in order to improve the centering positioning of the plate falling into the plate positioning area 101 in the second direction, two groups of second positioning components are provided, and accordingly, four second accommodating grooves 1013 are provided. The four second accommodating grooves 1013 are arranged in pairs at the opposite ends of the plate positioning area 101 in the second direction, and the two groups of second positioning components are arranged at intervals in the first direction.

[0058] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the attached claims.
