Description

Technical Field

[0001] This utility model relates to a conveying trolley, specifically a double-layer orthogonal conveying trolley. Background Technology

[0002] During the processing, conveyor trolleys are often used to transport materials to the corresponding workstations for processing.

[0003] A conveyor trolley is a piece of equipment used in automated production lines and logistics transportation. It generally has a single-layer conveyor structure and can transport a precision board such as a circuit board substrate.

[0004] Some conveyor trolleys have a double-layer conveying structure. Since the boards occupy little longitudinal space, two boards can be conveyed at a time. In order to reduce the overall height and volume of the conveyor trolley, the space for placing boards on the conveyor trolley is usually small. After the conveyor trolley conveys the boards to the designated position, the boards need to be transferred to other conveyor lines. Manual transfer is time-consuming and labor-intensive, with low efficiency and increased labor costs. At the same time, it is easy to damage the circuit board due to errors, which also increases labor costs and is inconvenient. Utility Model Content

[0014] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0015] like Figure 1-2As shown, a double-layer orthogonal conveying trolley includes a base 1 with multiple automatically rotatable rollers 11 on the base 1. The rollers 11 are located at the bottom of the base 1, and a drive motor is installed on the side of the base 1 to drive the rollers 11 to rotate automatically, so as to drive the conveying trolley to move automatically and convey plates. A support frame 2 is provided above the base 1, and a first fixed frame 3 and a second fixed frame 4 are provided above the support frame 2. The support frame 2, the first fixed frame 3, and the second fixed frame 4 are all located above the base 1 and are arranged sequentially from bottom to top. The top of the first fixed frame 3 and the top of the second fixed frame 4 are respectively provided with multiple orderly arranged first rollers 31 and second rollers 41 arranged coaxially with the first rollers 31. All are driven by external geared motors to rotate. The first rollers 31 and the second rollers 41 are connected by chain or belt drives, respectively. The combined structures of the first rollers 31 and the first fixed frame 3, as well as the combined structures of the first rollers 31 and the first fixed frame 3, are existing technologies. These constitute a roller conveyor belt. A gap is provided between the top surface of the support frame 2 and the bottom surface of the first fixed frame 3, and a gap is provided between the top surface of the first fixed frame 3 and the bottom surface of the second fixed frame 4. The gap between the support frame 2 and the first fixed frame 3 is used for the vertical movement of the first chain conveyor belt 32, and the gap between the first fixed frame 3 and the second fixed frame 4 is used for the vertical movement of the second chain conveyor belt 42. Simultaneously, it accommodates plates and minimizes the longitudinal height of the conveyed trolley, thereby reducing... Due to its small size and weight, the first fixed frame 3 has multiple first chain conveyor belts 32, each located between two first rollers 31 and capable of automatic lifting, on its top. The second fixed frame 4 has multiple second chain conveyor belts 42, each located between two second rollers 41 and capable of automatic lifting, on its top. Both the first chain conveyor belts 32 and 42 are existing technologies and will not be described in detail here. The length directions of the first chain conveyor belts 32 and 42 are aligned with the axial directions of the first rollers 31 and 41, respectively. This allows the plates on the first rollers 31 and 41 to be automatically diverted and transported to other conveyor lines via the first chain conveyor belts 32 and 42. The plates are then transported to the first rollers 31 and 41... When the plates are on the two rollers 41, the top surfaces of the first and second chain conveyor belts 32 and 42 are lower than the top sides of the first and second rollers 31 and 41, respectively. When it is necessary to transfer the plates, both the first and second chain conveyor belts 32 and 42 are raised, so that the top surfaces of the first and second chain conveyor belts 32 and 42 are higher than the top sides of the first and second rollers 31 and 41, respectively. The plates are thus lifted by the first and second chain conveyor belts 32 and 42 and vertically reversed in the horizontal direction, transferring the two plates to other conveyor lines simultaneously without manual intervention in the reversal. This achieves automated reversal and transfer of the plates, avoiding damage caused by errors during plate reversal.This effectively improved the efficiency of sheet metal conveying and transfer while ensuring the stability of sheet metal conveying.

[0016] like Figure 1 As shown, the support frame 2 has multiple vertically arranged first support blocks 21 connected to the bottom edge of the first fixed frame 3 at its peripheral edge. These first support blocks 21 are fixed to the edge of the support frame 2 and connected to the first fixed frame 3, providing support to the edge of the first fixed frame 3, maintaining its stability, and increasing the gap between the support frame 2 and the first fixed frame 3. This facilitates the placement of plates and allows for the lifting and lowering of the first chain conveyor belt 32. The first fixed frame 3 also has multiple vertically arranged second support blocks 33 connected to the bottom edge of the second fixed frame 4 at its peripheral edge. These second support blocks 33 are fixed to the edge of the first fixed frame 3 and connected to the second fixed frame 4, providing support to the edge of the second fixed frame 4, maintaining its stability, and increasing the gap between the support frame 2 and the first fixed frame 3. The gap between the two fixed frames 4 facilitates the accommodation of the plates and the lifting and lowering of the second chain conveyor belt 42. Two horizontally rotatable first limiting cylinders 34 are provided on both sides of the top edge of the first fixed frame 3 corresponding to the width direction of the first chain conveyor belt 32. Two horizontally rotatable second limiting cylinders 43 are provided on both sides of the top edge of the second fixed frame 4 corresponding to the width direction of the second chain conveyor belt 42. Each first limiting cylinder 34 and each second limiting cylinder 43 are respectively located at the edge of the first fixed frame 3 and the edge of the second fixed frame 4. They can limit the plates during the conveying of the plates, prevent the plates from shifting significantly and falling out of the first fixed frame 3 and the second fixed frame 4, and ensure that the plates are always located on the first roller 3 and the second roller 4, thereby ensuring the stable and reliable conveying of the plates.

[0017] like Figure 1-2As shown, support rods 22 are provided on both sides of the support frame 2 and the first fixed frame 3, parallel to the first roller 31. The support rods 22 are horizontally positioned between the support frame 2 and the first fixed frame 3. The bottom of the first fixed frame 3 is provided with a groove 35 that mates with the support rods 22. The groove 35 mates with the side wall of the support rods 22 to increase the movable space of the support rods 22 during lifting and lowering. The ends of the two support rods 22 are connected by connecting rods 23 that protrude from the outside of the support frame 2. The two support rods 22 and the two connecting rods 23 are vertically connected to form a rectangular structure. The top surfaces of the two connecting rods 23 are connected to the bottom surface of the first chain conveyor belt 32. The connecting rods 23 are located on the outer side of the gap between the support frame 2 and the first fixed frame 3. The top of the first fixed frame 3 and the top of the second fixed frame 4 are respectively provided with a means to accommodate the first roller 31. The receiving grooves of the first chain conveyor belt 32 and the second chain conveyor belt 42 are designed to reduce the longitudinal space occupied by the first chain conveyor belt 32 and the second chain conveyor belt 42, and to increase the longitudinal movable space of the first chain conveyor belt 32 and the second chain conveyor belt 42. A vertically arranged U-shaped bracket 24 is provided on the top surface of the connecting bar 23. The top surface of the U-shaped bracket 24 is connected to the bottom surface of the second chain conveyor belt 42. The U-shaped bracket 24 is located on the top of the connecting bar 23 on the outer side and is vertically arranged. The top of the U-shaped bracket 24 is close to the bottom of the second chain conveyor belt 42. The connecting bar 23 supports and fixes the bottom surfaces of both ends of the first chain conveyor belt 32, and the U-shaped bracket 24 supports and fixes the bottom surfaces of both ends of the second chain conveyor belt 42. At the same time, the supporting bar 22, the connecting bar 23 and the U-shaped bracket 24 are interconnected to form a whole.

[0018] like Figure 2 As shown, one of the U-shaped supports 24 is equipped with a first geared motor 25 and a second geared motor 26, which are respectively connected to the first chain conveyor belt 32 and the second chain conveyor belt 42. The first geared motor 25 and the second geared motor 26 are existing technologies and will not be described in detail here. Both the first geared motor 25 and the second geared motor 26 are connected to the side wall of the U-shaped support 24 and can respectively drive the first chain conveyor belt 32 and the second chain conveyor belt 42 to transport the plates. Fixing plates 27 are provided on the inner sides of multiple included angles between the support bar 22 and the connecting bar 23. Below the fixing plates 27, corresponding to the side wall of the support frame 2, are fixing members 28. The component 28 is equipped with a vertically arranged drive cylinder 281. The cylinder rod output end of the drive cylinder 281 is connected to the fixed plate 27. The bottom of the drive cylinder 281 is fixedly connected to the fixing component 28 on the side wall of the support frame 2. The connection between the cylinder rod output end of the drive cylinder 281 and the fixed plate 27 allows the drive cylinder 281 to drive the connecting rod 23 and the support rod 22 to move up and down synchronously. This, in turn, drives the first chain conveyor belt 32 and the second chain conveyor belt 42 to move up and down synchronously through the connecting rod 23 and the U-shaped bracket 24. This lifts the plate for reversing the conveying of the plate or moves it down to its original position so that the first roller 31 and the second roller 41 can convey the plate.

[0019] like Figure 1-2 As shown, the top surface of the peripheral edge of the base 1 is provided with multiple linear guide rails 12 that are connected to the bottom surface of the support frame 2 and are arranged along the conveying direction of the first roller 31. The linear guide rails 12 are existing technology and can support and guide the lateral movement of the support frame 2 and the first fixed frame 3 and the second fixed frame 4 above it. The base 1 is provided with an adjusting cylinder 13 arranged in the same direction as the linear guide rails 12. The bottom of the support frame 2 is provided with a connecting block 29 connected to the output end of the adjusting cylinder 13. The adjusting cylinder 13 is a conventional cylinder in the prior art. It can drive the support frame 2 to move laterally through the connecting block 29 to adjust the lateral position of the support frame 2 and the first fixed frame 3 and the second fixed frame 4 above it. Thus, when the conveying trolley is transferred to a designated position and docked, the lateral position of the support frame 2 and the first fixed frame 3 and the second fixed frame 4 above it can be finely adjusted by the adjusting cylinder 13 to accurately dock with other conveying lines and ensure that the plates can be accurately and stably conveyed to other conveying lines.

[0020] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
