Description

Technical Field

[0001] The utility model relates to the field of PCB production equipment, in particular to a PCB conveying equipment used in a detection section. Background Art

[0002] In the production process of PCB boards, it is necessary to test the PCB boards after each process is completed to ensure the yield of the produced PCB boards.

[0003] At present, the inspection method for PCB boards is as follows: after the PCB boards have completed a process, they are stacked together and transported to the inspection section for inspection. During the inspection, the inspection personnel take out the PCB boards one by one from the stack of PCB boards for inspection. However, since the PCB boards are thin and have a smooth surface, it is difficult for the inspection personnel to take the PCB boards out of the stack of PCB boards, which will affect the inspection process and make it difficult to improve the inspection efficiency.

[0004] Based on this, the utility model provides a PCB conveying device for a testing section, which is used to convey PCB boards to testers one by one, so that it is convenient for testers to take the PCB boards, thereby achieving the purpose of improving the testing efficiency of PCB boards. Utility Model Content

[0005] Based on this, it is necessary to provide a PCB conveying equipment for a detection section, including a frame, a conveying mechanism is arranged on the frame, a horizontal conveying surface is formed on the conveying mechanism, and the conveying direction of the conveying surface is from left to right; a top plate mechanism is also arranged on the frame, and the top plate mechanism is located below the right side of the conveying surface, and the top plate mechanism includes a support portion fixed on the frame by a mounting frame, the upper end of the support portion extends upward over the conveying surface, and the upper end of the support portion is a plane with a lower left and a higher right side, forming an inclined surface, the left end of the inclined surface is located below the conveying surface, and the right end of the inclined surface is located above the conveying surface.

[0006] The utility model is used for conveying a PCB board to be inspected, specifically, for conveying a PCB board before completing an SMT process, wherein the left end of the conveying surface is used to connect with the conveying structure of an equipment of a previous process, and is used to receive the equipment of the previous process, so that after the equipment of the previous process completes the corresponding operation, the PCB board can be directly conveyed to the conveying surface for conveying, wherein, in the process of the conveying surface conveying the PCB board, after the PCB board is conveyed to the top plate mechanism, the right end of the PCB will be lifted up by the inclined surface extending above the conveying surface, so that the right end of the PCB board can be lifted up from the conveying surface, at this time, due to the gap between the PCB board and the conveying surface, the inspector can conveniently take the PCB board from the conveying surface, thereby effectively reducing the time spent by the inspector in the process of taking the board, and effectively improving the inspection efficiency of the inspector for the PCB board.

[0007] Furthermore, there are two support parts, which are arranged along the front-to-back direction.

[0008] In the utility model, the number of the supporting parts is two, and correspondingly, the number of the inclined surfaces is also two. In the process of the PCB board being transported by the conveying surface to its right end and climbing up the inclined surface, the existence of the two inclined surfaces can make the PCB board be supported by the inclined surfaces more stably, thereby effectively preventing the PCB board from sliding off the inclined surfaces during the climbing process of its right end, thereby ensuring that the PCB board can smoothly form a gap between it and the conveying surface at the top plate mechanism, thereby ensuring that the inspection personnel can easily pick up the PCB board transported in front of them.

[0009] Furthermore, the top plate mechanism also includes a photoelectric switch, which is fixed on the mounting frame of the support part through a connecting arm, the photoelectric switch is located between the two support parts, and the photoelectric switch is located below the inclined surface; the frame is also provided with a first driving device for driving the conveying mechanism to operate, and the first driving device is communicatively connected to the photoelectric switch.

[0010] In the utility model, the photoelectric switch is located between the two supporting parts and below the inclined surface. Therefore, when the PCB board climbs onto the inclined surface under the conveying of the conveying surface, if the PCB board climbs above the photoelectric switch, it can be detected by the photoelectric switch. At this time, the photoelectric switch will send a signal to the first driving device. After receiving the signal, the first driving device stops its driving of the conveying surface, so that the PCB board can stay on the conveying surface, which can effectively avoid the detection personnel from failing to take the PCB board in time and causing the PCB board to collide with the top plate mechanism.

[0011] Furthermore, the conveying mechanism includes two first transmission rollers arranged on the left and right, and three conveying belts mounted on the two first transmission rollers and drivingly connected to the two first transmission rollers, the three conveying belts are arranged in sequence in the front-to-back direction; the upper end surfaces of the three conveying belts are located on the same horizontal plane to form a conveying surface, and among the three conveying belts, gaps are formed between adjacent conveying belts, and the supporting portion extends through the gap to above the conveying belt; the photoelectric switch is also located above the conveying belt.

[0012] In the utility model, the first driving device can be a motor connected to one of the two first transmission rollers, used to drive the first transmission roller connected thereto to rotate, thereby driving the three conveying belts sleeved on the first transmission roller to move, thereby realizing the conveying of the PCB board by the conveying surface. The gap formed between the three conveying belts can be used for the support part to pass through, thereby realizing the purpose of extending the inclined surface on the support part to the upper side of the conveying surface.

[0013] Furthermore, the surfaces of the two first transmission rollers are provided with annular grooves corresponding to the conveyor belts, and the conveyor belts are sleeved in the corresponding annular grooves.

[0014] In the utility model, the conveyor belt is sleeved in the corresponding annular groove, so that when the first transmission roller drives the conveyor belt to move, the conveyor belt can be prevented from moving relative to the first transmission roller in the front-rear direction, that is, the gap between the three conveyor belts can always exist. Preferably, the width of the annular groove is slightly larger than the width of the conveyor belt, for example, 3-7 mm wide, to ensure the smooth operation of the conveyor belt in the annular groove.

[0015] Furthermore, a guide mechanism is also provided on the frame, and the guide mechanism is located on the left side of the top plate mechanism, and includes a first guide plate and a second guide plate arranged front to back, and the first guide plate and the second guide plate are both arranged along the left and right directions, and the lower ends of the first guide plate and the second guide plate are both abutted against the conveying surface, and a guide channel is formed between the first guide plate, the second guide plate and the conveying surface, and the left ends of the first guide plate and the second guide plate are bent forward and backward respectively to form a first inclined section and a second inclined section.

[0016] In the utility model, the guide channel formed between the first guide plate and the second guide plate is used for the passage of the PCB board conveyed by the conveying surface, wherein the width of the guide channel needs to be slightly larger than the width of the PCB board, preferably 1-2 mm wider than the width of the PCB board, so that the position of the PCB board on the conveying surface can be adjusted, thereby ensuring that the position of the PCB board on the top plate mechanism remains consistent each time, which can further facilitate the inspection personnel to perform the PCB board on the top plate mechanism. Removal operation.

[0017] Furthermore, the support part includes two second transmission rollers rotatably arranged on the mounting frame, the two second transmission rollers are arranged along the front-to-back direction, and the height of the second transmission roller on the right side is higher than the height of the second transmission roller on the left side, and the two second transmission rollers are also sleeved with transmission belts drivingly connected to the second transmission rollers, and the upper end surface of the transmission belt forms an inclined surface; a second driving device drivingly connected to the second transmission roller is also arranged on the mounting frame corresponding to the second transmission roller, and the second driving device is drivingly connected to the photoelectric switch.

[0018] In the utility model, the second driving device can be a motor connected to one of the two second transmission rollers, used to drive the second transmission roller connected thereto to rotate, thereby driving the transmission belt to move, so as to realize the transmission belt to convey the PCB board that climbs onto the transmission belt, thereby ensuring that the PCB board can smoothly climb onto the inclined surface, and at the same time, can reduce the friction between the PCB board and the inclined surface. The second driving device is connected to the photoelectric switch in communication, and after the PCB board moves above the photoelectric switch, the second driving device will also stop driving the second transmission roller.

[0019] The principle and effect of the present invention are further described below in combination with the above technical solutions and the accompanying drawings:

[0020] In the utility model, the left end of the conveying surface is used to connect with the conveying structure of the equipment of the previous process, and is used to receive the equipment of the previous process, so that after the equipment of the previous process completes the corresponding operation, the PCB board can be directly conveyed to the conveying surface for conveying. In the process of the conveying surface conveying the PCB board, after the PCB board is conveyed to the top plate mechanism, the right end of the PCB will be lifted up by the inclined surface extending above the conveying surface, so that the right end of the PCB board can be lifted up from the conveying surface. At this time, due to the gap between the PCB board and the conveying surface, the inspection personnel can easily pick up the PCB board from the conveying surface, thereby effectively reducing the time spent by the inspection personnel in the board picking process, and effectively improving the inspection efficiency of the inspection personnel for the PCB board.

[0032] The utility model is used for conveying PCB boards to be inspected, specifically, for conveying PCB boards before completing an SMT process, wherein the left end of the conveying surface is used to connect with the conveying structure of the equipment of the previous process, and is used to receive the equipment of the previous process, so that after the equipment of the previous process completes the corresponding operation, the PCB board can be directly conveyed to the conveying surface for conveying, wherein, in the process of the conveying surface conveying the PCB board, after the PCB board is conveyed to the top plate mechanism, the right end of the PCB will be lifted up by the inclined surface 413 extending above the conveying surface, so that the right end of the PCB board can be lifted up from the conveying surface, at this time, due to the gap between the PCB board and the conveying surface, the inspector can easily pick up the PCB board from the conveying surface, thereby effectively reducing the time spent by the inspector in the process of taking the board, and effectively improving the inspection efficiency of the inspector for the PCB board.

[0033] In one embodiment, there are two support portions 41 , which are arranged along the front-to-back direction.

[0034] In this embodiment, there are two supporting parts 41, and correspondingly, there are also two inclined surfaces 413.

At this time, the photoelectric switch 512 will send a signal to the first driving device.

Among them, the gap formed between the three conveying belts 22 can be used for the support part 41 to pass through, so as to achieve the purpose of extending the inclined surface 413 on the support part to the upper side of the conveying surface.

Preferably, the width of the annular groove is slightly larger than the width of the conveyor belts 22, for example, 3-7 mm wide, to ensure the smooth operation of the conveyor belts 22 in the annular groove.
