[0024] Example

[0025] Reference Figure 1 The utility model provides a PCB board turnover vehicle, including a frame 1, a support frame 2 and a support plate 3, wherein the support frame 2 is arranged on the frame 1, the support frame 2 includes a first inclined portion 21 and a second inclined portion 22, the first inclined portion 21 is connected to the second inclined portion 22 and is arranged at an angle α, the support plate 3 is arranged on the first inclined portion 21, the support plate 3 abuts against the board surface of the PCB board, the second inclined portion 22 abuts against the edge of the PCB board, a first avoidance opening 211 is opened on one side of the first inclined portion 21, and a second avoidance opening 221 corresponding to the first inclined portion 21 is opened on one side of the second inclined portion 22.

[0026] In the present application, since the first inclined portion 21 is inclined, the PCB board leans against the first inclined portion 21 to prevent the PCB board from tipping forward; in addition, since the first inclined portion 21 and the second inclined portion 22 are set at an angle α, the PCB board is stably stored between the two during transportation, which can withstand the inertia of acceleration or deceleration during transportation, and avoids mutual collision between PCB boards and causing damage to the PCB boards; at the same time, since the first avoidance opening 211 and the second avoidance opening 221 are provided, it is convenient for the clamp or the staff to grab the PCB board.

[0027] In actual use, the angle α can be 70°-100°.

[0028] Preferably, the angle between the first inclined portion 21 and the horizontal direction is 55°, and the angle between the second inclined portion 22 and the horizontal direction is 35°. Therefore, when the first inclined portion 21 and the second inclined portion 22 are set at an angle, the angle α between the two is 90°, so that the support frame 2 is an L-shaped structure. In addition, the length of the second inclined portion 22 is 200mm. According to the thickness of the PCB board of 1.6,mm, the temporary storage capacity of the PCB board in this application is 120 pieces, so the temporary storage capacity of the PCB board can be ensured. In addition, the support plate 3 can adopt a 15mm thick bakelite board to ensure the bearing capacity of the support plate 3. The frame 1 can be designed with two materials. When used in a clean room, brushed stainless steel is used to make the frame 1 to ensure that the dust content meets the standard. When used in a non-clean room, in order to reduce production costs, the frame 1 is made of carbon steel paint. The above only lists some relatively preferred embodiments of the PCB board turnover vehicle. Those skilled in the art can set various parameters of the PCB board turnover vehicle according to actual application conditions.

[0029] Reference Figure 1 , Figure 3 and Figure 5In a feasible embodiment, a height adjustment device 4 is provided at the bottom of the support frame 2, and the height adjustment device 4 is used to adjust the height of the support frame 2 on the frame 1. Since the support frame 2 can be adjusted by the height adjustment device 4, the PCB board turnover vehicle in this embodiment can be connected to the PCB collection and unloading machines with different conveying heights, or it is convenient for workers of different heights to collect boards.

[0030] Preferably, the height adjustment device 4 comprises a cross bar 41, a threaded rod 42, a first bolt 43 and a second bolt 44. A through hole 11 is provided on the vehicle frame 1 for the threaded rod 42 to pass through. The cross bar 41 is fixedly connected to the bottom of the support frame 2. One end of the threaded rod 42 is connected to the cross bar 41, and the other end passes through the through hole 11. The first bolt 43 and the second bolt 44 are both threadedly connected to the threaded rod 42 and are respectively located on both sides of the through hole 11. When the first bolt 43 and the second bolt 44 are screwed to the desired height, the first bolt 43 can prevent the support frame 2 from moving downward, and the second bolt 44 can prevent the support frame 2 from moving upward. With the cooperation of the first bolt 43 and the second bolt 44, the support frame 2 is fixed at the desired height.

[0031] Reference Figure 1 and Figure 3 In a feasible embodiment, a first positioning hole 23 is provided on the support frame 2, and a second positioning hole 34 corresponding to the first positioning hole 23 is provided on the support plate 3. In this embodiment, sensors can be provided corresponding to the first positioning hole 23 and the second positioning hole 34, and the sensors can sense whether the PCB boards on the first inclined portion 21 have been taken out through the first positioning hole 23 and the second positioning hole 34; or the first positioning hole 23 and the second positioning hole 34 can be detected by the mechanical arm of the board collecting machine. If the mechanical arm detects the first positioning hole 23 and the second positioning hole 34, it means that the PCB boards have been taken out. The above positioning method has a simple structure and strong practicality.

[0032] Reference Figure 2 In a feasible embodiment, the frame 1 includes a support column 12 and a load-bearing frame 13. The support columns 12 are provided with four, and the load-bearing frame 13 is a rectangular structure. The four support columns 12 correspond to and are fixedly connected to the four corners of the load-bearing frame 13, respectively. The load-bearing frame 13 and the support columns 12 can provide sufficient support force for the frame 1 to ensure the stability of the frame 1. Furthermore, the end of the support column 12 is provided with a universal wheel 5. The universal wheel 5 makes it very convenient to move the turnover vehicle, avoids unnecessary loading and unloading and turnover, and saves time and effort.

[0033] Reference Figure 2In a feasible embodiment, an identification code 6 is provided on one side of the carrier 13. In this embodiment, the identification code 6 can be identified by an AGV (Automated Guided Vehicle). An AGV is an industrial vehicle that loads goods automatically or manually, automatically drives along a set route or pulls a cargo trolley to a designated location, and then loads and unloads goods automatically or manually. The AGV can be used to scan the identification code 6 to obtain the identification information of the frame 1. The identification code 6 can be a barcode or a QR code, etc. In this embodiment, by setting the identification code 6, the AGV can easily obtain the identification information of the frame 1 to be loaded. Specifically, a 100*100 square box is laser-marked on one side of the carrier 13 facing the ground, and a cross line is marked in the middle, with a line width of 0.5mm and a marking depth of 0.1mm. Its main function is to attach the AGV identification QR code and ensure that the QR code is completely consistent with the bottom and is not damaged.

[0034] Reference Figure 2 In a feasible embodiment, the frame 1 is provided with a handrail 7. The handrail 7 facilitates workers to transfer the frame 1 without using an AGV.

[0035] Reference Figure 4 In a feasible embodiment, the support plate 3 includes a first support plate 31, a second support plate 32 and a telescopic mechanism 33, wherein the first support plate 31 is fixed on the support frame 2, the telescopic mechanism 33 is respectively connected to the support frame 2 and the second support plate 32, and the telescopic mechanism 33 drives the second support plate 32 to move relative to the first support plate 31. In this embodiment, since the first support plate 31 can be displaced relative to the second support plate 32, when a PCB board with a larger area needs to be transported, the second support plate 32 can be moved out so that the board surfaces between the first support plate 31 and the second support plate 32 are flush, and the PCB board is placed on the two support plates 3. Exemplarily, a first slide rail is provided on the first support plate 31, and a second slide rail matching the first slide rail is provided on the second support plate 32. Under the guiding action of the first slide rail and the second slide rail, the second support plate 32 can be displaced relative to the first support plate 31.

[0036] Preferably, the telescopic mechanism 33 comprises a rotating disk 331, a curved rod 332 and a swing rod 333. The rotating disk 331 is rotatably arranged on the supporting frame 2, the swing rod 333 is fixedly connected to the rotating disk 331, one end of the curved rod 332 is rotatably connected to the swing rod 333, and the other end is fixedly connected to the second supporting plate 32. When the rotating disk 331 rotates, the swing rod 333 is driven to swing. Driven by the swing rod 333, the curved rod 332 drives the second supporting plate 32 to move relative to the first supporting plate 31, so that when the overall area of ​​the supporting plate 3 needs to be increased, the second supporting plate 32 moves out from behind the first supporting plate 31; when it is not necessary to save the space occupied by the supporting plate 3, the second supporting plate 32 moves into the back of the first supporting plate 31 to be hidden.

[0037] In order to achieve the purpose of hiding, the first support plate 31 is fixed on the first inclined portion 21 by a mounting column, and the second support plate 32 is provided with an open groove adapted to the mounting column. When there is no need to save the space occupied by the support plate 3, the mounting column enters the open groove. In addition, while the turntable 331 rotates relative to the support frame 2, it can also be extended and retracted along the axial direction of the turntable 331 relative to the support frame 2, so as to achieve the purpose of the second support plate 32 and the first support plate 31 being flush or the second support plate 32 being retracted behind the first support plate 31. The specific way to achieve the extension and retraction of the turntable 331 can be: a rotating shaft is set on the support frame 2, the turntable 331 is rotatably set on the rotating shaft, a spring is set between the rotating shaft and the turntable 331, and the extension and retraction between the two are controlled by the spring. In order to improve the stability when the second support plate 32 and the first support plate 31 are flush, a limit column extending along the axial direction of the turntable 331 can be set on the support frame 2, and the turntable is provided with a card hole adapted to the limit column. When the limiting column is engaged in the locking hole, the rotation of the rotating disk 331 is limited, thereby improving the stability when the second support plate 32 is flush with the first support plate 31. The above only lists some embodiments of the second support plate 32 being telescopic relative to the first support plate 31. Those skilled in the art can set the second support plate 32 in a telescopic manner in the prior art.
