Description

Technical Field

[0001] The utility model relates to the technical field of PCB board conveying, and more specifically, to a split PCB board conveying mechanism. Background Art

[0002] PCB boards, also known as printed circuit boards or printed circuit boards, are widely used in electronic products. During the processing of PCB boards, one of the more important processes is to transport the PCB boards into the oven for baking by using a pallet truck. The main purpose is to remove moisture and remove the moisture contained in the PCB boards or absorbed from the outside. In the existing PCB board conveying mechanism, the pallet truck and the board rack for placing PCB boards are integrally formed, which means that the pallet truck and the board rack need to enter the high-temperature oven together. The temperature in the oven is as high as 200 degrees Celsius. The pallet truck is easily damaged when placed in the high-temperature oven for a long time. It is common that the wheels of the pallet truck are very noisy or not sensitive to rotation after being damaged, which increases the cost of later maintenance or replacement of the PCB boards. Moreover, the pallet truck and the board rack are mutually restricted after being integrally formed. On the one hand, it requires at least two people to operate at the same time to send the entire car and the board rack into or out of the oven. On the other hand, the pallet truck also makes it difficult to clean the glue stains on the board rack, affecting the quality of the PCB board. Utility Model Content

[0025] The drawings of the present invention are only used for illustrative purposes and cannot be construed as limiting the present invention. In order to better illustrate the following embodiments, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0026] Example 1

[0027] like Figure 1 , Figure 2 and Figure 4 As shown, this embodiment discloses a split PCB board conveying mechanism, including a plug-in board rack 100 for placing PCB boards, a pallet transporter 200 for transporting the plug-in board rack 100, and a first roller device 300 arranged at the bottom of the oven for assisting in conveying the plug-in board rack 100, wherein the pallet transporter 200 includes a frame 210, wherein the frame 210 and the plug-in board rack 100 are preferably made of stainless steel. A pair of universal wheels 211 and a pair of directional wheels 212 are arranged at the bottom of the frame 210. A second roller device 220 and a pedal device 230 are arranged on the frame 210, and the second roller device 220 is used to carry the plug-in board rack 100. A wedge block 110 is arranged at a position corresponding to the pedal device 230 on the plug-in board rack 100, and the wedge block 110 and the pedal device 230 are detachably connected, thereby making the plug-in board rack 100 and the pallet transporter 200 detachably connected.

[0028] like Figure 3As shown, further, at least one layer of plug-in unit is provided on the plug-in rack 100, preferably two layers of plug-in unit, which is too high for operators to place PCB boards. Wherein, each layer of plug-in unit includes an upper wave plate 120, a lower wave plate 130 arranged up and down, and a side wave plate 140 arranged on at least one side. The upper wave plate 120, the lower wave plate 130 and the side wave plate 140 are all provided with wave-shaped grooves to facilitate fixing the PCB board. Wherein, a hollow square tube 150 is provided on the front and rear ends of the upper wave plate 120, and the hollow square tube 150 is sleeved on the plug-in rack 100 and movably connected with the plug-in rack 100, thereby making the upper wave plate 120 and the plug-in rack 100 movably connected; a bolt 160 is also provided on the hollow square tube 150, and the bolt 160 is used to fix the hollow square tube 150 on the plug-in rack 100, thereby fixing the upper wave plate 120 on the plug-in rack 100. When a PCB board needs to be placed, the upper wave plate 120 needs to be moved slightly upward to prevent the PCB board from colliding with the upper wave plate 120, wherein the hollow square tube 150 moves on the board rack 100, thereby driving the upper wave plate 120 to move; the setting of the bolt 160 can fix the position of the upper wave plate 120 to prevent the upper wave plate 120 from slipping during the placement of the PCB board; after the PCB board is placed, the upper wave plate 120 needs to be moved downward so that the upper wave plate 120 can limit and fix the PCB board to prevent the PCB board from being damaged by collision during movement.

[0029] like Figure 4 and Figure 5 As shown, specifically, the frame 210 includes side panels 213 arranged at the left and right ends of the second roller device 220, and the side panels 213 extend upward to a certain height for positioning the plug-in plate rack 100, and can also prevent the plug-in plate rack 100 from tipping over due to tilting left and right when the frame 210 moves.

[0030] Furthermore, the rear end of the side plate 213 is connected to a fixing frame 214, and the pedal device 230 is arranged at the bottom of the fixing frame 214. The fixing frame 214 is also provided with an elastic buffer structure, a handle structure 215 and a gong card box 216. The elastic buffer structure is arranged on the side opposite to the plug-in board frame 100. When the plug-in board frame 100 is transferred to the pallet transport vehicle 200, the plug-in board frame 100 may collide with the fixing frame 214 due to inertia, and the elastic buffer structure can be used to prevent the plug-in board frame 100 from directly colliding with the fixing frame 214. The gong card box 216 and the handle structure 215 are arranged on the opposite side of the elastic buffer structure, and the gong card box 216 is arranged below the handle structure 215; the front end of the side plate 213 is a slope structure 2131 that gradually tilts outwards, and the slope structure 2131 is used to guide the plug-in board frame 100 to move to the middle of the two side plates 213.

[0031] like Figure 6As shown, in this embodiment, the pedal device 230 includes a support block 231, a fixing ring 232 and a linkage rod 233, wherein the support block 231 is fixedly connected to the fixing frame 214, the fixing ring 232 is fixed on the support block 231, and the linkage rod 233 passes through the fixing ring 232 and is movably connected to the fixing ring 232. One end of the linkage rod 233 serves as a snap-fit ​​structure for detachably connecting with the wedge block 110, and the other end serves as a pedal structure. When the linkage rod 233 is in a horizontal position, the snap-fit ​​structure of the linkage rod 233 is snap-fitted with the wedge block 110. When force is applied to the pedal structure to move downward, the snap-fit ​​structure of the linkage rod 233 moves upward with the support block 231 as a fulcrum, thereby releasing the connection with the wedge block 110. The relationship between the pedal structure, the support block 231 and the buckling structure can refer to the principle of the lever. When force is applied to the pedal structure to move it downward, the buckling structure moves upward as a force point, so that the wedge block 110 is loosened from the buckling structure, and the connection with the wedge block 110 can be released, so that the plug-in plate rack 100 can be transported to the oven alone.

[0032] Furthermore, the front side of the wedge block 110 is opposite to the PCB board, and the rear side is opposite to the pedal device 230, and the front side of the wedge block 110 is a straight surface, and the rear side is an inclined surface. When the wedge block 110 is buckled and connected with the pedal device 230, the front side of the wedge block 110 is in contact with the pedal device 230, so setting the front side of the wedge block 110 as a straight surface can better prevent the wedge block 110 from being loosened from the pedal device 230. And setting the rear side of the wedge block 110 as an inclined surface, when the wedge block 110 moves toward the pedal device 230 along with the plug-in board rack 100, the inclined surface is conducive to the wedge block 110 sliding into the buckling structure, thereby achieving a fixed connection with the pedal device 230.

[0033] like Figure 7 As shown, further, the second roller device 220 includes a plurality of second positioning rods 221 fixed on the side plate 213 and a second roller 222 sleeved on the positioning rod. The second roller 222 is movably mounted on the second positioning rod 221. The arc surface on the second roller 222 is conducive to the movement of the plug-in board rack 100. When the plug-in board rack 100 moves on the second roller 222 device 220, the second roller 222 rotates, thereby driving the plug-in board rack 100 to move, thereby reducing the work intensity of the operator. Preferably, the number of the second rollers 222 is 5 to 10.

[0034] like Figure 2As shown, further, the first roller device 300 includes a rolling frame 310 with a generally U-shaped structure design, a plurality of first positioning rods (not shown in the figure) fixed to the inner side of the U-shaped structure of the rolling frame 310, and a first roller 320 sleeved on the first positioning rod, and the first roller 320 is movably mounted on the first positioning rod. When the plug-in plate rack 100 is pushed to the entrance of the oven, the setting of the first roller 320 device 300 is conducive to the plug-in plate rack 100 to move quickly into the oven through inertia, thereby further reducing the work pressure of the staff. When the plug-in plate rack 100 is pulled out of the oven, the first roller 320 device 300 can also play a role in assisting the pulling out, which is more conducive to people's operation. Preferably, the number of the first rollers 320 is 6 to 12.

[0035] Furthermore, the U-shaped opening of the rolling frame 310 is arranged outward, and the two ends of the rolling frame 310 are inclined structures 2131 that gradually tilt outward, which are used to guide the plate rack 100 to move toward the middle of the two side plates 213. The bottom of the rolling frame 310 is provided with a support foot 330 that can be retracted and adjusted in height, and the first roller 320 and the second roller 222 are on the same horizontal plane, so that when the plate rack 100 is pushed into the oven from the pallet transporting vehicle 200 or when the plate rack 100 is pulled out of the oven onto the pallet transporting vehicle 200, the first roller 320 and the second roller 222 can be perfectly transitioned, without the need for the operator to lift the plate rack 100 for transfer.

[0036] Obviously, the above embodiments of the utility model are only examples for clearly explaining the technical solution of the utility model, and are not intended to limit the specific implementation methods of the utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the claims of the utility model shall be included in the protection scope of the claims of the utility model.
