[0001] This utility model relates to the field of PCB board conveying equipment, and in particular to a sub-frame positioning mechanism for PCB boards. Background Technology

[0002] However, the conveying process of a PCB board (such as a thin board, a flexible board, or a board material whose edges need to be protected) includes a sub-frame and a mother frame. The PCB board is placed in the sub-frame, and then the sub-frame is inserted into the mother frame, thereby achieving the protection of the PCB board and convenient transportation.

[0003] Therefore, how to release the subframe from clamping and positioning the PCB board, and how to place the PCB board inside the subframe to protect the PCB board's perimeter and transport it, are key aspects of automated design. Utility Model Content

[0007] The positioning device and the support frame cooperate to confine the sub-frame between them;

[0008] The clamping device is used to drive the positioning clamping page to swing away from the rectangular frame.

[0009] The advantages of this application are:

[0010] 1. The same set of equipment can realize the board receiving or board placement process between the sub-frame and the board, which improves the applicability of the product. At the same time, by changing the size of the sub-frame, it can be used for boards of different sizes.

[0011] 2.

[0043] like Figures 1 to 14 As shown, a sub-frame positioning mechanism for a PCB board includes:

[0044] Rack 1,

[0045] AGV trolley 20 is used to transport mother frame 3. Mother frame 3 has multiple spaced sub-frames 30. Sub-frames 30 are used to attach and cover the outer periphery of the sheet material (the outer periphery can be completely covered or partially covered).

[0046] The conveyor belt 2 is used to drive the mother frame 3 to move along the length direction and position the sub-frame 30 in a predetermined clamping position;

[0047] The sub-frame 30 includes a rectangular frame and a positioning clamping page 32 disposed on the front wall of the rectangular frame. The positioning swing is disposed on the front wall of the rectangular frame and can swing at a position that is close to the rectangular frame and at a position that is far away from it.

[0048] The clamping device 40 is located above the clamping position and is mounted on the vertical moving frame 4. The vertical moving frame 4 can drive the clamping device 40 to switch between the position of extending into the mother frame 3 and the position of exiting the mother frame 3.

[0049] Depending on whether the plate is being retracted or released, when the plate is being retracted, the clamping device 40 moves the sub-frame 30 from the position where it exits the mother frame 3 to the position where it extends into the mother frame 3.

[0050] When the plate is placed, the clamping device 40 extends into the mother frame 3 to clamp the sub-frame 30, and then exits the mother frame 3.

[0051] The frame-unloading mechanism 5 is used to receive the sub-frame 30 of the clamping device 40. The frame-unloading mechanism 5 includes a vertically arranged base 50, a support frame 51 provided on the base 50, a positioning device 6 provided on the front wall of the support frame 51, and an opening clamping device 7 provided on the rear wall of the base 50.

[0052] The support frame 51 is distributed in a frame shape;

[0053] The positioning device 6 and the support frame 51 cooperate to confine the sub-frame 30 between them;

[0054] The clamping device 7 is used to drive the positioning clamping page 32 to swing away from the rectangular frame.

[0055] A multi-axis robotic arm 9 is provided with an adsorption component, which is used to clamp the sheet material and switch between vertical and horizontal positions.

[0056] Specifically, the support frame 51 is slidably mounted on the base 50.

[0057] The support frame 51 is provided with a first driving device for the sliding of the driving base 50.

[0058] The structure of the support frame 51 is movable, which avoids the sub-frame 30 from falling off due to the shaking of the clamping device 40 during movement, thus improving the stability of the operation. At the same time, the stroke between the two is shorter, reducing interference and improving the working efficiency.

[0059] Specifically, the first driving device includes guide rails disposed on both sides of the base 50 and sliders slidably mounted on the guide rails, the sliders being disposed on both sides of the support frame 51.

[0060] The front wall of the base 50 is provided with a first telescopic device 52, and the driving end of the first telescopic device 52 is connected to the middle of the support frame 51. The first telescopic device 52 can be a telescopic mechanism or a telescopic cylinder; other telescopic mechanisms, such as a lead screw structure, can also be used.

[0061] This enabled the overall movement of the support frame 51.

[0062] Specifically, the upper wall of the support frame 51 is provided with clearance areas 53 on both sides, which are used for the clamping device 40 to extend into. This ensures the cooperation between the clamping device 40 and the sub-frame 30. In actual movement, when the clamping device 40 drives the sub-frame 30 to cooperate with the support frame 51, the sub-frame 30 is just in contact with the front support strip 81 of the support frame 51.

[0063] Specifically, the front wall of the support frame 51 is provided with rectangularly distributed support bars 81, and the outer side of the support bars 81 is provided with positioning bars 82. The front wall of the positioning bars 82 protrudes beyond the predetermined thickness of the front wall of the support bars 81. The thickness is compatible with the thickness of the rectangular frame, that is, it clamps the sub-frame 30 and has no effect on the thickness of the PCB board. Therefore, only the size of the sub-frame 30 needs to be changed to accommodate different board materials, thereby improving the versatility of the equipment.

[0064] The support bars 81 located on both sides are equipped with multiple sets of guide wheels 54 arranged along the height direction.

[0065] The positioning device 6 includes a rotating device 60 disposed on the rear wall of the positioning strip 82 and a swing arm 61 disposed on the driving end of the rotating device 60. The swing arm 61 can swing between a position extending into the front wall of the support strip 81 and a position away from the support strip 81.

[0066] When the swing arm 61 is positioned on the front wall of the support bar 81, the swing arm 61 and the support bar 81 form a positioning area to clamp the rectangular frame. This reasonable positioning and layout of the support bar 81, positioning bar 82, and swing arm 61 achieves a compact device design while simultaneously meeting clamping requirements.

[0067] Specifically, the rectangular frame is provided with a through hole 33, which is disposed opposite to the clamping page 32. The rectangular frame and the clamping page 32 are pivotally connected by an elastic hinge 34, which can apply an elastic force to the clamping page 32 to fit against the rectangular frame.

[0068] In another embodiment of the flexible hinge, the rectangular frame and the clamping page are pivotally connected and attracted to each other by a magnetic structure, allowing for opening using...

[0069] The clamping device 7 is a second telescopic device provided on the support frame 51, and the driving end of the second telescopic device is provided with a push block 71.

[0070] The push block 71 is provided with elastic rollers on both sides.

[0071] The second telescopic device can drive the push block 71 through the through hole 33 and abut against the rear wall of the clamping page 32, which is used to move the clamping page 32 away from the positioning frame 31.

[0072] Structures such as limiting protrusions can be provided at the position of the clamping page 32 to prevent the periphery of the sheet metal from extending into the position of the through hole 33.

[0073] The main design feature of this application is that, through the cooperation of the through hole 33 and the second telescopic device 70, the sheet metal can be removed or placed into the sub-frame 30.

[0074] When the clamping page 32 needs to be opened, the adsorption component needs to be attached to the board material first, thus ensuring the placement of the board material.

[0075] When the board is being retracted, the clamping page 32 is in the open state. After the adsorption component brings the board material into contact with the support bar 81, the clamping device 7 moves away and then the clamping page 32 is closed, thereby achieving the positioning of the board material.

[0076] Specifically, the vertical moving frame 4 includes a vertical column (which is suspended inside the chassis), a vertical guide rail disposed on the vertical column, a vertical slider disposed on the vertical guide rail, and a vertical lead screw pair for driving the vertical slider to move.

[0077] The vertical slider extends horizontally with a horizontal frame.

[0078] The clamping device 40 has two sets respectively located on the lower wall of the horizontal frame.

[0079] The clamping device 40 includes a bidirectional clamping motor and two grippers 42 driven by the bidirectional clamping motor 41, thereby realizing the loading and unloading of the sub-frame 30.

[0080] Specifically, the adsorption assembly includes a cross 90, an adjusting rod located at one end of the cross 90, and a suction cup 92 located on the bottom wall of the adjusting rod.

[0081] The adjusting rods are provided in four parts and are arranged in a frame shape;

[0082] The adjusting rod can be adjusted to a predetermined position located on the cross 90.

[0083] The cross 90 has a through hole 93 in the middle, which is used for the tube to be inserted.

[0084] The adjusting rod is provided with a vacuum channel 94, and the inner wall of the adjusting rod is provided with a connecting hole 95. The suction cup 92 is connected to the vacuum channel 94.

[0085] Compared with the existing multi-axis robot 9, the tube is inserted through the through hole 93 in the middle of the cross 90 and then connected directly or through the connection hole 95 of the adjusting rod, which effectively avoids the problem of tube winding, improves the stability of the equipment, and makes the assembly process simpler and more stable.

[0086] Furthermore, a telescopic device or a manual adjustment device is used to adjust the relative position between the adjustment rods, thus making it suitable for different sheet sizes.

[0087] A conveying method for a three-axis take-up and untake-down plate machine with a mother-daughter frame.

[0088] The above-mentioned multi-axis take-up and untake-down board machine with three parent and child frames includes:

[0089] Step 1:

[0090] The conveyor belt 2 drives the mother frame 3 to move step by step, and aligns the slots of the mother frame 3 with the clamping positions of the clamping device 40.

[0091] The clamping device 40 is driven by the vertical moving frame 4 to penetrate the mother frame 3 and clamp the child frame 30.

[0092] Step Two:

[0093] When the plate is released, the clamping device 40 rises to the same horizontal position as the frame release mechanism 5, and the first driving device drives the support frame 51 to move toward a position that fits against the sub-frame 30, and positions the clamping devices 40 on both sides in the avoidance area 53 of the support frame 51.

[0094] At this point, the sub-frame 30 is in contact with the support strip 81.

[0095] Step 3:

[0096] The rotating device 60 drives the swing arm 61 to rotate, and the swing arm 61 and the support bar 81 form a positioning range, thereby achieving the limitation of the four sides of the sub-frame 30.

[0097] Step 4: The multi-axis robotic arm 9 drives the adsorption component to adhere to the board material and perform vacuum adsorption for positioning;

[0098] Step 5: The second telescopic device 70 drives the push block 71 through the through hole 33, moves the clamping page 32 and moves the clamping page 32 away from the edge of the board;

[0099] Step Six: The multi-axis robot 9 drives the adsorption component to move horizontally to exit the unpacking mechanism 5, and then drives the sheet material to the horizontal buffer stage and releases it for predetermined testing (such as CCD photography, scratch detection, processing, etc.).

[0100] A conveying method for a three-axis receiver with a mother-daughter frame.

[0101] The above-mentioned multi-axis take-up and untake-down board machine with three parent and child frames includes:

[0102] Step 1: The multi-axis robot 9 picks up the board material of the horizontal buffer table through the adsorption component, and after vertically rising a predetermined stroke, it swings to the vertically placed position and rises a predetermined height before moving towards the unpacking mechanism 5.

[0103] Step 2: At this time, the swing arm 61 clamps the positioning frame 31, the push block 71 abuts against the clamping page 32 and makes the clamping page 32 open, the multi-axis robot 9 moves horizontally and places the sheet material into the positioning frame 31 and fits it;

[0104] Step 3: The second telescopic device 70 retracts, and the clamping page 32 clamps the sheet material between the positioning frame 31 and the clamping page 32;

[0105] Step 4: The vacuum adsorption pressure of the adsorption component comes into contact, and the multi-axis robot 9 moves the adsorption component away;

[0106] Step 5: The vertical moving frame 4 drives the clamping device 40 to rise to the clamping position;

[0107] Step 6: The first driving device drives the base 50 to slide and positions the clamping device 40 in the clearance area 53. Then, the clamping device 40 descends to a predetermined position and clamps the upper end of the sub-frame 30.

[0108] Step 7: The rotating device 60 drives the swing arm 61 to rotate, and then the first driving device drives the base 50 away from the sheet material;

[0109] Step 8: The vertical moving frame 4 drives the sub-frame 30 to be vertically inserted into the slot of the mother frame 3, wherein the upper end of the sub-frame 30 is provided with extended limiting parts on both sides for limiting.
