A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0050] In the description of this article, it should be understood that the terms "upper", "lower", "left", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0051] In the description of this specification, the description with reference to the terms "an embodiment", "example", etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example.

[0052] In addition, it should be understood that although this specification is described according to implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.

[0053] Unless specifically stated or defined otherwise, the term “and / or” used in the present invention includes any and all combinations of one or more of the associated listed items.

[0054] For the convenience of description, unless otherwise specified, the up and down directions mentioned below are the same as Figure 1 The up and down directions of the same, the first rotation direction described below is Figure 6 The rotation direction of the middle rotating seat from left to right ( Figure 6 The second rotation direction described below is Figure 6 The rotation direction of the middle rotating seat from right to left ( Figure 6 counterclockwise direction).

[0055] In the related art, small parts such as boards and cards need to be inspected by testing equipment after processing to detect whether the solder joints and other parts of the parts are qualified. Among them, boards and cards are a kind of printed circuit boards. In the computer field, motherboards, sound cards, graphics cards, etc. can all be called boards and cards. When testing parts such as boards and cards, in the board and card production line, the boards and cards on the conveying channel are blocked and positioned by using a blocking device. The blocking device keeps the boards and cards at the current position until the testing equipment completes the testing of the boards and cards. There are two main schemes for the existing blocking devices. The first scheme is to use an upper and lower ejection blocking seat, and the blocking seat is driven up and down by a pen-shaped cylinder. When the blocking seat is at the top, the boards and cards on the conveying channel of the production line can be blocked by the blocking seat. In the first solution, since the height of the blocking seat needs to meet the requirement of 80mm, the cylinder stroke is relatively long, resulting in a large space for the installation of the blocking device in the vertical direction next to the conveying channel, and a large space for the blocking seat to move up and down to avoid air. When the height of the blocking plate card needs to be very high, the space below the plate card cannot be arranged with the blocking device. At the same time, in this blocking method, the distance between the position where the blocking device contacts the plate card and the position where the blocking device is fixedly installed is long, and the force arm is long, so that the blocking seat cannot withstand high impact force and the structure is unstable. The second solution of the blocking device adopts a horizontally extended blocking seat. Due to the frame position limitation of the production line, the horizontal arrangement space is also relatively small. It is necessary to set a horizontally extended blocking seat under the cylinder, and drive the blocking seat to extend the blocking plate card through the ultra-thin cylinder. In the second solution, the extension length of the blocking seat is fixed, and the blocking seat cannot block special-shaped and protruding plates and cards, and it is easy to collide with components such as light sources. In addition, since the conveyor belt of the conveyor of the production line is installed on the track plate, the track plate needs to be notched to facilitate the blocking seat to extend from above the belt. At this time, the notch position will cause a jam; at the same time, there is a gap between the blocking seat and the belt, and the thin plate card will easily cause a jam. The above two types of blocking seats can only be used in fixed positions. Due to structural size limitations, they are not universal and cannot be interchanged.

[0056] In order to solve the problems in the above-mentioned related technologies, the present application provides a blocking device, wherein the blocking seat of the blocking device can be driven by a rotating seat to move to the conveyor belt of the conveyor to block the board and card, and the track plate of the conveyor does not need to have a gap through which the blocking seat passes. The blocking seat is movably installed on the rotating seat, and the relative position of the blocking seat and the rotating seat can be adjusted, so as to adjust the extension length or position of the blocking seat, and adjust the distance between the blocking end of the blocking seat and the conveyor belt, which can meet a variety of blocking needs, not only can it block different types of boards and cards such as irregular shapes and protrusions, but also can prevent the blocking seat from colliding with the light source of the detection device or other devices on the production line, thereby improving the scope of application of the blocking device. The blocking device is mainly used in board and card production lines, and can also be used in other parts production lines that need to be detected.

[0057] like Figures 1 to 3 As shown, the blocking device 1 provided by the present application comprises a base 10, a rotating base 11 having a pivot end 115 and a movable end 116, a driver 12 drivingly connected to the rotating base 11 for driving the rotating base 11 to rotate, and a blocking base 13 having a connecting end 131 and a blocking end 132. The pivot end 115 of the rotating base 11 is rotatably mounted on the base 10, the base 10 is used to support the rotating base 11, the rotating axis of the rotating base 11 is horizontally arranged, and the movable end 116 of the rotating base 11 can rotate relative to the base 10.

[0058] The distance between the pivot end 115 and the movable end 116 is relatively fixed. The pivot end 115 and the movable end 116 are arranged at intervals along a first straight line direction perpendicular to the rotation axis of the rotating seat 11. The connection end 131 and the blocking end 132 are arranged at intervals along a second straight line direction perpendicular to the rotation axis of the rotating seat 11, that is, the first straight line direction, the second straight line direction, and the rotation axis of the rotating seat 11 are mutually perpendicular. The connection end 131 of the blocking seat 13 is movably mounted on the movable end 116 of the rotating seat 11 to adjust the distance between the blocking end 132 and the rotation axis of the rotating seat 11. The movable mounting includes sliding mounting and detachable mounting, thereby changing the distance between the blocking end 132 and the rotation axis of the rotating seat 11. After adjusting the distance between the blocking end 132 and the rotation axis of the rotating seat 11, the connection end 131 of the blocking seat 13 and the movable end 116 of the rotating seat 11 can be fixed relatively by fasteners, positioning clamps, etc., or the blocking seat 13 of different lengths can be replaced. By moving the blocking seat 13 along the second straight line direction to change the position on the rotating seat 11, the distance between the blocking end 132 of the blocking seat 13 and the rotation axis of the rotating seat 11 changes, so that the position of the blocking end 132 when blocking the board 3 changes, that is, the extension length of the blocking end 132 of the blocking seat 13 is changed. When the blocking device 1 is used, the installation position of the blocking seat 13 can be adjusted according to the types of detection equipment and boards 3 on the production line, thereby improving the application range of the blocking device 1. In addition, by changing the extension length of the blocking seat 13, the blocking seat 13 can withstand greater impacts, heavier boards 3 and higher impact speeds.

[0059] In one embodiment, the blocking device 1 further comprises a connecting member 14. The rotating seat is provided with a first mounting structure, and a plurality of second mounting structures are provided at the connecting end of the blocking seat along the rotating direction of the rotating seat, and any second mounting structure is connected to the first mounting structure through the connecting member.

[0060] and / or,

[0061] The rotating seat is provided with a plurality of first mounting structures along the rotating direction of the rotating seat, and a second mounting structure is provided at the connecting end of the blocking seat, and the second mounting structure is connected to any first mounting structure through a connecting member.

[0062] Specifically, the first mounting structure is a positioning hole 111 provided on the rotating seat 11, and the second mounting structure is a plurality of connecting holes 133 provided on the connecting end 131. The connecting member 14 passes through the positioning hole 111 and any connecting hole 133, and the connecting end 131 of the blocking seat 13 is connected to the movable end 116 of the rotating seat 11 through the connecting member 14. The connecting member 14 is a fastener such as a screw or a bolt, and the positioning hole 111 and the connecting hole 133 are threaded holes, and the locking and positioning of the blocking seat is achieved through the connecting member 14. When the blocking seat 13 needs a longer extension length, the connecting member 14 passes through the positioning hole 111 and the connecting hole 133 away from the blocking end 132. Similarly, when the blocking seat 13 needs a shorter extension length, the connecting member 14 passes through the positioning hole 111 and the connecting hole 133 close to the blocking end 132. In addition, a plurality of positioning holes 111 may also be provided.

[0063] It is understandable that in other embodiments, a strip-shaped groove may be provided on the connection end 131 to replace the plurality of connection holes 133 .

[0064] Furthermore, a slide groove 112 is provided on the rotating seat 11, and the slide groove 112 penetrates the rotating seat 11 along the second straight line direction. The positioning hole 111 is connected to the slide groove 112, and the connecting end 131 of the blocking seat 13 is slidably arranged in the slide groove 112, so that the position and extension length of the blocking seat 13 can be conveniently adjusted by sliding the blocking seat 13.

[0065] In one embodiment, the driver 12 includes a cylinder 121 having a sliding rod 122 and a driving seat 123 installed on the sliding rod 122; a first pivot 15 is provided on the base 10, the driving seat 123 has a second pivot 124, and the rotating seat 11 is provided with a first axial hole 113 and a second axial hole 114. The first axial hole 113 is opened at the pivot end 115 of the rotating seat 11, and the axis of the first axial hole 113 and the axis of the second axial hole 114 are both horizontally arranged and parallel to each other. The pivot end 115 of the rotating seat 11 is sleeved on the first pivot 15 through the first axial hole 113, and the rotating seat 11 is sleeved on the second pivot 124 through the second axial hole 114, so that the driver 12 drives the rotating seat 11 to rotate.

[0066] Furthermore, a third pivot 104 is provided on the base 10, and the cylinder 121 is installed on the base 10 through the third pivot 104. The rotational power is provided by the cylinder 121. The cylinder 121 is installed on the base 10 through a machine base 125. The machine base 125 is installed on the base 10 through the third pivot 104. The third pivot 104 is a boss screw. When the cylinder 121 is actuated, it can slightly rotate around the boss screw to ensure non-interference in movement.

[0067] Optionally, the first pivot 15 is a shoulder screw, which passes through the first shaft hole 113 and is locked by a lock nut, and the drive seat 123 is a Y-type joint.

[0068] like Figures 3 to 9 As shown, in one embodiment, the blocking seat 13 includes a straight plate 134 and a bent plate 135. The connecting end 131 is located on the straight plate 134, and the blocking end 132 is located on the bent plate 135. One end of the bent plate 135 is connected to the straight plate 134, and the other end of the bent plate 135 is bent and extended along the rotation path of the rotating seat 11. The bent plate 135 can be bent at 90 degrees, in a circular arc trajectory, or in a broken line. When the blocking seat 13 rotates, the bent plate 135 can be rotated and pressed down to achieve blocking and positioning of the board 3.

[0069] In one embodiment, a limiting plate 16 is installed on the base 10, and the rotating seat 11 has an extension block 117, which is integrally formed with the rotating seat 11 body. The second shaft hole 114 is opened in the extension block 117, and the rotating seat 11 has a first rotation direction and a second rotation direction opposite to the first rotation direction. The rotating seat 11 and the blocking end 132 of the blocking seat 13 are arranged in sequence along the first rotation direction, and the limiting plate 16 is located on the rotation path of the extension block 117 of the rotating seat 11 along the second rotation direction. When the rotating seat 11 rotates along the first rotation direction, the blocking end 132 of the blocking seat 13 can block the board 3, and when the rotating seat 11 rotates along the second rotation direction, the blocking end 132 of the blocking seat 13 can release the board 3.

[0070] The rotating seat 11 of the present application has a pivot end 115 with a first shaft hole 113 and a movable end 116 with the blocking seat 13 installed, an extension block 117 is provided on the pivot end 115, a second shaft hole 114 is provided in the extension block 117, the pivot end 115 and the movable end 116 are arranged at intervals along the first straight line direction, the connection end 131 and the blocking end 132 are arranged at intervals along the second straight line direction, the first straight line direction, the second straight line direction, and the rotation axis direction of the rotating seat 11 are mutually perpendicular, the projection of the extension block 117, the pivot end 115, and the blocking end 132 along the first straight line direction are arranged in sequence along the second straight line direction, and the limiting plate 16 is located on the movement path of the extending block 117. The limiting plate 16 serves as an angle limiter when the rotating seat 11 rotates and retracts along the second rotation direction, limits the rotation angle of the rotating seat 11 when it retracts, and finally limits the height of the blocking seat 13.

[0071] like Figure 6 As shown in the figure: the first straight line direction is the vertical direction, the second straight line direction is the horizontal direction, and after the extension block 117, the pivot end 115, and the blocking end 132 are projected along the vertical direction, the projection points of the extension block 117, the pivot end 115, and the blocking end 132 are arranged in sequence along the second straight line direction, that is, the extension block 117, the pivot end 115, and the blocking end 132 are arranged in sequence from left to right in the figure, so that the limiting plate 16 is limited when the rotating seat 11 is retracted.

[0072] In one embodiment, an anti-collision rubber pad 17 is provided on the rotating seat 11, and the rotation axis of the rotating seat 11 and the anti-collision rubber pad 17 are arranged in sequence along the first rotation direction. When the rotating seat 11 rotates along the first rotation direction, the blocking end 132 of the blocking seat 13 extends to block the board 3. The rotation axis of the rotating seat 11 and the anti-collision rubber pad 17 are arranged in sequence along the first rotation direction, and the anti-collision pad is located in front of the first rotation direction, and the anti-collision pad abuts against the back of the track before the rotating seat 11. The anti-collision rubber pad 17 is fixed to the rotating seat 11 through the mounting hole. When the rotating seat 11 moves close to the board 3, the rotating seat 11 will stick to the back of the track, so the anti-collision rubber pad 17 abuts against the back of the track to play a buffering role.

[0073] Furthermore, the blocking device 1 further includes a bushing 18. The bushing 18 is installed in the first shaft hole 113 and sleeved on the first pivot 15. The oil-free bushing 18 has the characteristics of low friction coefficient, high wear resistance, low cost, strong low-speed load-bearing capacity and small size and space requirements, and is very suitable for use in scenes with low speed and slight impact. The installation size and space requirements of the bushing 18 are not high, which facilitates the miniaturization of parts. An oil-free bushing 18 is press-fitted at both ends of the first shaft hole 113.

[0074] Optionally, the base 10 is provided with an escape groove 102 and a third shaft hole 103 connected to the escape groove 102, and the pivot end 115 of the rotating seat 11 is installed in the escape groove 102 through the first pivot 15 passing through the first shaft hole 113 and the third shaft hole 103. The first pivot 15 passes through two oil-free bushings 18 and is installed in the first shaft hole 113. The first pivot 15 is a shoulder screw, and the threaded end of the first pivot 15 is fixed by a locking nut 19, which has a simple and reliable structure and low parts cost. The two oil-free bushings 18 serve as rotating bearings to reduce the rotational friction and reduce the wear of parts.

[0075] Key References Figures 6 to 9 As shown, the blocking seat 13 can be installed and adjusted to have different extension positions to meet the compatibility of production lines of different models. In this embodiment, two different extension position distances are used, so the connecting end 131 can be opened with two connecting holes 133.

[0076] The first extended position is a short extended position. When the blocking seat 13 is installed in the short extended position, the extended length A in the blocking state is 16 mm. When retracted, the highest point of the blocking seat 13 is 14.5 mm from the upper surface of the track plate. The extended position of the blocking seat 13 is used in production lines where the minimum height of the light source is above 15 mm, which can meet the requirement that the blocking seat 13 is not higher than 15 mm, preventing the risk of hitting the light source in abnormal situations.

[0077] In the second extended position, the limit plate 16 may not be installed. The extended length C of the blocking seat 13 is 16mm or 26mm, and the height D of the highest point of the blocking seat 13 from the upper surface of the track plate does not exceed 22.4mm when retracted. The blocking seat 13 is used in the production of light sources with a minimum height of more than 25mm, and has a wider range of use scenarios, and different blocking positions can be selected according to customer needs.

[0078] like Figure 10 to Figure 11 As shown, at the same time, the embodiment of the present application also provides a board production line, including a board production line, including a conveying device 2 with a conveying channel 21 and the above-mentioned blocking device 1. The conveying channel 21 is located on the rotation path of the blocking end 132 of the blocking seat 13. Specifically, the conveying device 2 includes a frame 22 with a track plate, a belt or a conveyor belt installed on the frame 22, the conveying channel 21 is located on the conveyor belt, and the conveying channel 21 is located in the rotation path of the blocking end 132. When the blocking end 132 of the blocking seat 13 rotates, it will move into the conveying channel 21 to achieve blocking of the board 3 in the conveying channel 21. After the detection is completed, the blocking end 132 of the blocking seat 13 can leave the conveying channel 21, and the conveyor belt will transport the board 3 away.

[0079] The production line adopts the above-mentioned blocking device 1 and utilizes a blocking seat with an adjustable extension length, thereby avoiding collision between the blocking seat and detection equipment and other equipment on the production line, and is suitable for the production of different types of boards.

[0080] In one embodiment, the base 10 is provided with a first positioning portion, and the conveying device 2 is provided with a second positioning portion, and the first positioning portion is engaged with the second positioning portion to achieve the installation of the blocking device 1 on the conveying device 2.
