Description

Technical Field

[0001] The utility model relates to equipment in a PCB board manufacturing process, in particular to a safety insurance device for collecting PCB boards, which is used to improve production safety and reduce potential safety hazards. Background Art

[0002] During the production process of PCB boards, they usually need to go through the following steps: cutting and grinding → drilling → outer layer graphics → (full board gold plating) → etching → inspection → silk screen solder mask → (hot air leveling) → silk screen characters → appearance processing → testing → inspection. Since the entire process involves multiple assembly line operations, the board needs to be transported from the previous process to the next process through a temporary storage rack.

[0003] Usually, the temporary storage rack adopts an electric lifting type, and the height of the temporary storage rack is adjusted according to the height of the assembly line (unloading conveyor line-plate collector) so that the trolley carrying the plate material (on the plate collector) can slide smoothly to the temporary storage rack. In actual operation, since the lifting of the temporary storage rack is not automatic and needs to be adjusted manually, it cannot be ensured that the temporary storage rack is flush with the plate collector. In this way, the trolley will roll over and slide back when retreating along the roller of the plate collector, posing a safety hazard. At this stage, without any fool-proofing and error-proofing mechanisms, it is impossible to prevent safety incidents caused by human negligence, improper operation and other problems. Summary of the invention

[0004] The utility model aims to provide a safety insurance device for PCB board collection. By installing this device, the board collection machine can be prevented from retreating in the event of level inconsistency, thereby greatly improving safety protection. No special experience or special training is required, the device is easy to use, and the occurrence of industrial accidents can be effectively prevented.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a safety insurance device for PCB board collection, including a limit mechanism, a fixing mechanism and a touch mechanism, the limit mechanism is located between the board collection machine and the temporary storage rack, the limit mechanism includes a seesaw structure, one end of the long plate of the seesaw structure is a baffle, and the other end is connected to the touch mechanism, the seesaw structure is installed on the unloading port of the board collection machine through the fixing mechanism, the touch mechanism includes a bracket and a touch head, the touch head is arranged on the bracket and is flush with the conveying plane of the board collection machine, when the platform surface of the temporary storage rack is against the touch head, the touch end of the seesaw structure is lifted up, and the baffle end falls down, which is lower than the conveying plane, and this is the passage mode; when the touch end falls and resets, the baffle end moves up under the action of the reset spring and is higher than the conveying plane, and this is the blocking mode.

[0006] In the above technical solution, the seesaw structure includes a pressure plate connected to the baffle, a rotating shaft located between the unloading port of the plate collector and the temporary storage rack, and a connecting plate fixed to the bracket, the connecting plate is located on one side of the temporary storage rack, the pressure plate is located on one side of the plate collector, and the reset spring is arranged under the pressure plate. When in the passing mode, the reset spring is compressed, and when in the blocking mode, the reset spring is reset, and the pressure plate is lifted and reset.

[0007] In the above technical scheme, the fixing mechanism includes an upper fixing plate and a lower fixing plate, and the upper and lower fixing plates are respectively composed of L-shaped steel plates. The fulcrum of the seesaw structure is a rotating shaft, which is welded to one side of the L-shape of the upper fixing plate, and the other side is riveted to the side plate of the plate collector; the lower fixing plate is fixed to the inner side of the side plate of the plate collector, and one end of the return spring is fixed to the lower fixing plate, and the other end is fixed to the pressure plate of the seesaw structure.

[0008] In the above technical solution, a vertically arranged slide groove is provided on the baffle plate, and an adjustment bolt fixed to the pressure plate is slidably connected in the slide groove, and the baffle plate has the freedom to adjust up and down along the extension direction of the slide groove.

[0010] Due to the application of the above technical solution, the utility model has the following advantages compared with the prior art:

[0011] 1. In the utility model, a limit mechanism is provided to prevent the PCB board from tipping over when the PCB board is collected. After the temporary storage rack is flush with the conveying roller of the PCB collecting machine, the limit mechanism is unlocked and descended, and the trolley carrying the PCB board can slide smoothly onto the temporary storage rack to complete the collection of the PCB board, thereby avoiding the safety problem caused by the temporary storage rack not adjusting the height, and improving production safety;

[0012] 2. A seesaw structure is used to form a limit mechanism. When the temporary storage rack is lifted up and hits the touch control mechanism, one end of the seesaw structure is lifted up and the other end must drop. The baffle is pulled down and is lower than the conveying roller. At this time, the PCB board trolley placed on the conveying roller can slide back. On the contrary, when the temporary storage rack does not hit the touch head, one end of the baffle is lifted up and reset under the action of the reset spring. At this time, the baffle is higher than the conveying roller, which blocks the PCB board trolley on the conveying roller from sliding. The structure is ingenious and easy to implement.

[0019] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0020] Example 1: See Figures 1 to 5 As shown, a safety insurance device for PCB board collection includes a limit mechanism, a fixing mechanism and a touch mechanism. The limit mechanism is located between a board collection machine 1 and a temporary storage rack 2. The limit mechanism includes a seesaw structure. One end of the long plate of the seesaw structure is a baffle 3, and the other end is connected to the touch mechanism. The seesaw structure is installed at the unloading port of the board collection machine 1 through the fixing mechanism. The touch mechanism includes a bracket 4 and a touch head 5. The touch head 5 is arranged on the bracket 4 and is flush with the conveying plane of the board collection machine 1. When the platform surface of the temporary storage rack 2 is against the touch head 5, the touch end of the seesaw structure is lifted up, and the baffle end falls down and is lower than the conveying plane. At this time, it is a passage mode; when the touch end falls and resets, the baffle end moves up under the action of the reset spring 6 and is higher than the conveying plane. At this time, it is a blocking mode.

[0021] Specific structure such as Figure 3 As shown, the seesaw structure includes a pressure plate 7 connected to the baffle 3, a rotating shaft 7 located between the unloading port of the plate collector 1 and the temporary storage rack 2, and a connecting plate fixed to the bracket 4, the connecting plate is located on one side of the temporary storage rack 2, the pressure plate 7 is located on one side of the plate collector 1, and the reset spring 6 is arranged under the pressure plate 7. When in the passing mode, the reset spring 6 is compressed, and when in the blocking mode, the reset spring 6 rebounds, and the pressure plate 7 is lifted and reset.

[0022] The fixing mechanism includes an upper fixing plate 8 and a lower fixing plate 9, and the upper and lower fixing plates are respectively composed of L-shaped steel plates. The fulcrum of the seesaw structure is a rotating shaft 10, which is welded to one side of the L-shape of the upper fixing plate 8 and riveted to the side plate of the plate collector 1 on the other side; the lower fixing plate 9 is fixed to the inner side of the side plate of the plate collector 1, and one end of the return spring 6 is fixed to the lower fixing plate 9, and the other end is fixed to the pressure plate 7 of the seesaw structure.

[0023] like Figure 1 As shown, the baffle plate 3 is provided with a vertically arranged slide groove 11, and an adjusting bolt 12 fixed to the pressing plate 7 is slidably connected in the slide groove 11, and the baffle plate 3 has the freedom of upward and downward adjustment along the extending direction of the slide groove 11. That is, according to the height of the conveying roller shaft 13 (conveying plane) on the actual board receiving machine 1, or the installation height of the lower fixed plate 9, the height of the baffle plate 3 is appropriately adjusted, so as to meet the matching of the height of the baffle plate 3 and the moving track of the PCB board trolley 14, and the use is flexible and variable.

[0024] In this embodiment, the touch head 5 includes a touch panel 15 and a screw 16. The touch panel 15 is fixed to both ends of the bracket 4. The screw 16 passes through the screw hole on the touch panel 15 and is fixed by a locking nut 17. The bottom end of the screw 16 is the contact point with the temporary storage rack 2. By adjusting the height position of the screw 16, it can better cooperate with the temporary storage rack 2 and be used more accurately and reliably.

[0025] During the production process, the PCB board trolley 14 is parked on the board collecting machine 1. After a certain number of PCB boards are collected, they are pulled to the temporary storage rack 2 at the rear. During this process, the height of the temporary storage rack 2 must match the height of the board collecting machine 1, otherwise the trolley will not be able to slide smoothly onto the temporary storage rack 2. Since the trolley carries multiple PCB boards and is heavy, once there is a drop in the horizontal plane of the slide, it is easy to cause a rollover, and the operator will subconsciously support the trolley, causing a safety accident. Therefore, the safety device in this embodiment, when the temporary storage rack 2 has not risen to a suitable height, the baffle 3 in the seesaw structure is higher than the conveying roller 13, blocking the slide of the PCB board trolley 14, such as Figure 5 Only when the operator readjusts the height of the temporary storage rack 2, and the platform surface of the temporary storage rack 2 is against the touch head 5, so that one end of the seesaw structure rises and the other end drops (that is, the baffle 3 drops), the PCB board trolley 14 can continue to retreat to the temporary storage rack 2, completing this process. Figure 4 shown.
