Referring to fig. 1 and 2 with additional reference to fig. 8, a blocking device 100 according to an embodiment of the first aspect of the present invention may be mounted on a mobile carrier 200, and includes: a mounting base 110, a blocking member 120, a driving member 130, a connecting member 140, and an elastic member 150. Wherein, the blocking member 120 is swingably mounted to the mounting base 110, and the first end 121 of the blocking member 120 extends out of the mounting base 110 and is switchable between the blocking position 101 (refer to fig. 3 and 4) and the releasing position 102 (refer to fig. 6) along with the swing of the blocking member 120; the driving member 130 is swingably mounted to the mounting base 110, and a second end 131 of the driving member 130 extends out of the mounting base 110; the connecting member 140 connects the blocking member 120 and the driving member 130, respectively, and at least one of the first connecting position 103 where the connecting member 140 is connected to the blocking member 120 and the second connecting position 104 (refer to fig. 5) where the connecting member 140 is connected to the driving member 130 can be changed; the resilient member 150 is arranged to drive the driving member 130 to bring the blocking member 120 into the blocking position 101.

In the embodiment, since the connecting member 140 connects the blocking member 120 and the driving member 130, respectively, when the driving member 130 is driven, the connecting member 140 drives the blocking member 120 to switch between the blocking position 101 and the releasing position 102 in a linkage manner, and further, since the elastic member 150 is provided to drive the driving member 130 so that the blocking member 120 is located at the blocking position 101, the material 210 carried by the mobile carrier 200 can be blocked even if the mobile carrier 200 has no power system.

It is contemplated that the blocking device 100 of the present embodiment may be applied to a mobile vehicle 200 having a power system, for example, a power source or an air source is disposed on the mobile vehicle 200, which can allow a driving device, such as a motor or an air cylinder, disposed on the mobile vehicle 200 to directly drive the second end 131 of the driving member 130, so as to swing the blocking member 120 to the release position 102. In addition, the blocking device 100 can also be applied to a mobile carrier 200 without a power system, that is, the mobile carrier 200 does not have a power source or an air source, in this case, when the mobile carrier 200 is transported to a device to be docked by a transport robot such as an AGV vehicle or a walking six-axis robot, the second end 131 of the driving element 130 of the blocking device 100 only needs to be abutted to the device to be docked and driven, that is, the blocking member 120 can be swung from the blocking position 101 to the release position 102 through the linkage of the connecting element 140, so that the transfer of the material 210 blocked by the blocking device 100 on the mobile carrier 200 is very convenient.

In addition, although the blocking device 100 is applied to the mobile carrier 200 in the embodiment, the blocking device is not limited thereto, and those skilled in the art can apply the blocking device to various apparatuses such as a logistics line according to the requirement.

It is conceivable that, referring to fig. 3, 4, the blocking position 101 refers to a position where the blocking member 120 restricts passage of, for example, the material 210, the tool, or the tray, etc. blocked by it; referring to fig. 6, the release position 102 refers to a position where the blocking member 120 allows passage of, for example, a material 210, a tool, a pallet, or the like, blocked by the blocking member.

It is contemplated that mounting base 110 may be a single component that is integrally formed or may be formed by assembling multiple sub-components.

It is conceivable that, in the above description, although the first end 121 of the blocking member 120 is described as extending out of the mounting base 110, a person skilled in the art should understand that: the fact that the first end portion 121 extends out of the mounting base 110 is not limited to the fact that the first end portion 121 must extend out of the mounting base 110 as a whole, but means that the first end portion 121 extends to a position where the mounting base 110 does not interfere with, for example, the material 210, the tool or the tray, and the like, and for example, when the mounting base 110 has a U-shaped groove shape, and the material 210, the tool or the tray, and the like, passes through the U-shaped groove of the mounting base 110, the first end portion 121 extends into the U-shaped groove, that is, the first end portion 121 extends out of the mounting base 110.

Also, while the second end 131 of the driver 130 is illustrated as extending out of the mounting base 110, those skilled in the art should understand broadly that: the fact that the second end 131 extends out of the mounting base 110 is not limited to the fact that the second end 131 must extend entirely out of the mounting base 110, but means that the second end 131 extends out of the mounting base 110 as long as the second end 131 extends to a position where the mounting base 110 does not interfere with, for example, a docking device, for example, when the mounting base 110 has a U-shaped groove and the docking device partially extends into the U-shaped groove of the mounting base 110, that means that the second end 131 extends out of the mounting base 110 as long as the second end 131 extends into the U-shaped groove.

Referring to fig. 2 and 4, in some embodiments, the connector 140 and the blocking member 120 are slidably coupled such that the first connection position 103 can be changed. Specifically, for example, the mounting base 110 is provided with a first mounting plate 112, a first rotating member 113 such as a rotating pin is mounted on the first mounting plate 112, and the first rotating member 113 extends in the front-rear direction, and correspondingly, the first intermediate portion 123 of the blocking member 120 is provided with a first rotating hole 124, and the first rotating hole 124 is fitted with the first rotating member 113 and rotates about the first rotating member 113. The first end portion 121 is disposed at an upper portion of the blocking member 120, is connected to an upper end of the first intermediate portion 123, and extends outward at an acute angle of, for example, approximately 60 ° with respect to the upper end of the first intermediate portion 123, for example, R1. The blocking member 120 is provided at a lower portion thereof with a third end portion 125, and the third end portion 125 is connected to a lower end of the first intermediate portion 123 and extends outward at an acute angle of, for example, approximately 60 ° with respect to the lower end of the first intermediate portion 123, for example, R2. Since the upper portion of the link 140 and the third end portion 125 are slidably connected to each other, the third end portion 125 of the stopper 120 slides with respect to the link 140 in conjunction with the driving of the link 140 by the driver 130, and the stopper 120 rotates about the first rotating member 113 so that the first end portion 121 of the stopper 120 swings in the vertical direction. When the first end 121 is swung down, the first end 121 is in the blocking position 101, enabling e.g. the material 210, the tool, the tray, etc. to be restrained, thereby preventing it from falling. When the first end portion 121 swings upwards, the first end portion 121 is in the release position 102, allowing for transfer of, for example, the material 210, a tool, a pallet, etc. By providing the link 140 and the stopper 120 to be slidably coupled so that the first coupling position 103 is changed, the link 140 and the stopper 120 can be prevented from being stuck, thereby smoothly swinging the stopper 120.

In some embodiments, one of the link 140 and the blocking member 120 is provided with the first guide portion 122, and the other is provided with the first slider 141, and the first slider 141 and the first guide portion 122 are fitted and slid along the first guide portion 122. This allows the connector 140 and the stopper 120 to be smoothly and slidably connected to each other. For example, a groove portion may be provided as the first guide portion 122 at the third end 125 of the blocking member 120, a sliding pin may be provided as the first slider 141 at the link 140, and the first slider 141 may be inserted into the first guide portion 122 in the front-rear direction and slid along the first guide portion 122. Thus, when the link 140 is driven, for example, in the up-down direction, the first slider 141 simultaneously pulls the blocking member 120 in the up-down direction, thereby swinging the blocking member 120.

Although the first guide portion 122 and the first slider 141 are described above as being provided to the stopper 120 and the link 140, the present invention is not limited thereto, and the first guide portion 122 and the first slider 141 may be provided to the link 140 and the stopper 120, respectively.

Referring to fig. 5 and 7, in some embodiments, the link 140 and the drive member 130 are slidably coupled such that the second connection position 104 can be changed. Specifically, for example, the mounting base 110 is provided with a second mounting plate 114, the second mounting plate 114 is substantially perpendicular to the first mounting plate 112, a second rotating member 115 such as a rotating pin is mounted on the second mounting plate 114, the second rotating member 115 extends in the left-right direction, i.e., the second rotating member 115 is substantially perpendicular to the first rotating member 113, and correspondingly, the second intermediate portion 133 of the driving member 130 is provided with a second rotating hole 134, and the second rotating hole 134 is fitted with the second rotating member 115 and rotates about the second rotating member 115. The second end portion 131 is provided at a lower portion of the driver 130, is connected to a lower end of the second intermediate portion 133, and extends outward at a substantially acute angle, for example, an angle of substantially 60 ° R3, with respect to the lower end of the second intermediate portion 133. The upper portion of the driving member 130 is provided with a fourth end portion 135, and the fourth end portion 135 is connected to the upper end of the second intermediate portion 133 and extends outwardly at a substantially acute angle, for example, at an angle of substantially 60 ° R4, with respect to the upper end of the second intermediate portion 133. The lower portion of the link member 140 and the fourth end portion 135 are slidably coupled, thereby enabling the link member 140 to be pulled as the driver 130 swings.

In some embodiments, one of the connecting member 140 and the driving member 130 is provided with the second guide portion 132, and the other is provided with the second sliding member 142, and the second sliding member 142 and the second guide portion 132 are fitted and slid along the second guide portion 132. This allows the connector 140 and the driver 130 to be smoothly slidably connected to each other. For example, a groove portion may be provided as the second guide portion 132 at the fourth end portion 135 of the driving member 130, a slide pin may be provided as the second slider 142 at the link 140, and the second slider 142 may be inserted into the second guide portion 132 in the left-right direction (the direction perpendicular to the paper surface in fig. 5 and 7) and slid along the second guide portion 132. Thus, when the driving member 130 is driven in the front-rear direction, the driving member 130 rotates about the second rotating member 115, the fourth end portion 135 swings and pulls the link member 140, thereby swinging the blocking member 120.

It is conceivable that the second guide 132 and the second slider 142 are provided to the driving member 130 and the connecting member 140, respectively, but the present invention is not limited thereto, and the second guide 132 and the second slider 142 may be provided to the connecting member 140 and the driving member 130, respectively.

It is conceivable that the above though in terms of: the example in which the connecting member 140 is slidably connected to the blocking member 120 and the driving member 130 to change the first connection position 103 at which the connecting member 140 is connected to the blocking member 120 and the second connection position 104 at which the connecting member 140 is connected to the driving member 130, thereby achieving the mutual linkage of the driving member 130, the blocking member 120 and the connecting member 140 has been described, but the invention is not limited thereto. For example, the connecting member 140 may be slidably connected to only the blocking member 120 (i.e., the first connection position 103 may be changed), and the connecting member 140 is hinged to the driving member 130 via a link member (not shown), so that the driving member 130, the blocking member 120 and the connecting member 140 are linked to each other. Alternatively, the connecting member 140 may be slidably connected to the driving member 130 only (i.e., the second connection position 104 may be changed), and the connecting member 140 is hinged to the blocking member 120 through a link member (not shown), so that the driving member 130, the blocking member 120 and the connecting member 140 are linked to each other. In addition, the connecting member 140 may be directly used as a link member, one end of which is slidably connected to one of the blocking member 120 and the driving member 130, and the other end of which is hinged to the other of the blocking member 120 and the driving member 130.

With continued reference to fig. 2, in some embodiments, the connecting member 140 is slidably mounted to the mounting base 110, one of the connecting member 140 and the mounting base 110 is provided with the third guide portion 111, the other is provided with the third slider 143, and the third slider 143 and the third guide portion 111 are fitted and slid along the third guide portion 111. Specifically, for example, on the inner side of the second mounting plate 114, a groove portion extending in the up-down direction is provided as the third guide portion 111, the link 140 has a plate shape, an edge of the link 140 serves as the third slider 143, and is inserted into the third guide portion 111, and when the driving member 130 is driven, the link 140 is pulled to slide up and down in the third guide portion 111, thereby driving the blocking member 120 to swing.

With continued reference to fig. 4 to 7, the blocking device 100 can thereby realize that the blocking member 120 swings in a plane composed of the up-down direction and the left-right direction when the driving member 130 is driven in the front-rear direction. Such a stopper device 100 is suitable for use in a mobile carrier 200 without driving power, for example, the mobile carrier 200 is transported in the front-rear direction by a transport robot, a protruding piece 211 is provided on an apparatus 300 to be docked with the mobile carrier 200, and the protruding piece 211 abuts against the second end 131 of the driving member 130 from the front direction when the mobile carrier 200 is docked with the apparatus 300, the fourth end 135 of the driving member 130 swings clockwise and forward around the second rotating member 115, and at the same time, the connecting member 140 is pulled to slide downward, and thereby the first end 121 of the stopper 120 is pulled to swing upward, so that the stopper 120 is switched from the stopping position 101 to the releasing position 102.

In some embodiments, the elastic member 150 is an inward contracting type elastic member 150, such as a tension spring, an elastic belt, etc., and has one end connected to the mounting base 110 and the other end connected to the driving member 130. Specifically, taking a tension spring as an example, one end of the tension spring is connected to the mounting base 110, for example, to the second mounting plate 114 of the mounting base 110, and the other end of the tension spring is connected to the driving member 130. More specifically, a tension spring is located at the rear side of the driving member 130, one end of the tension spring is connected to the second mounting plate 114 at the upper rear side with respect to the driving member 130, and the other end of the tension spring is connected to the driving member 130 above the second rotation hole 134, for example, the fourth end 135 of the driving member 130. Thereby, the driving member 130 can be reliably pulled in the rear direction, and thus the first end portion 121 of the blocking member 120 can be reliably placed in the blocking position 101.

Although the inwardly contracting elastic member 150 such as a tension spring has been described as the returning member, the returning member is not limited to this, and the returning member may be an outwardly expanding elastic member 150 such as a compression spring, a nitrogen spring, or a hydraulic shock absorber.

Further, although the above description has been made with the elastic member 150 having one end connected to the mounting base 110 and the other end connected to the driving member 130, the present invention is not limited thereto, and the elastic member 150 may have one end connected to the mounting base 110 and the other end connected to one of the connecting member 140 and the blocking member 120.

With continued reference to fig. 1 and 2, in some embodiments, the first end portion 121 is provided with a non-metallic blocking member 160. Specifically, the blocking member 160 may be directly locked to the rear of the first end portion 121 by a locking member (not shown) made of a non-metal material, such as a resin screw or a ceramic screw, so as to buffer the materials 210, tools, trays, etc. blocked by the blocking member 120 and prevent the metal material from contacting the materials 210, tools, trays, etc. The blocking member 160 may be made of a material having high compressibility, such as polyurethane, rubber, or silicone.

In some embodiments, the second end 131 is provided with a roller 170. Specifically, the rolling member 170 may be selected from rolling members 170 such as bearings, rollers, and the like, and is rollably mounted to the second end portion 131 through a rotating shaft, whereby abrasion of the second end portion 131 when struck can be reduced.

It is contemplated that, in the above embodiments, for example, the blocking member 120 may include two pieces respectively located at the left and right sides of the mounting base 110, the elastic member 150 may also include two pieces respectively located at the left and right sides of the mounting base 110, and correspondingly, the second mounting plate 114 may also include two pieces at the left and right sides, and the two elastic members 150 are respectively mounted at one end to one of the second mounting plates 114 and at the other end to respectively pull the driving member 130. This improves the left-right coordination and balance of the baffle device 100.

The blocking device 100 can be used in an automatic production line for manufacturing solar photovoltaic panels, and can mechanically block and limit the flower basket (i.e., the material 210) during the conveying process of the flower basket.

Referring to fig. 8, a mobile carrier 200 according to a second embodiment of the present invention, which can be carried by a transfer robot and is docked with a predetermined device, includes a carrier frame 220, and the mobile carrier 200 is provided with a blocking device 100 as described above.

In the present embodiment, since the blocking device 100 is provided, the mobile carrier 200 can block the material 210 placed on the mobile carrier 200 even if there is no power system. When the mobile carrier 200 is transported by, for example, a transport robot (not shown) to be docked with a predetermined device 300 (a device requiring docking), the stopper 120 can be switched from the stopping position 101 to the releasing position 102 only by driving the second end 131 of the driving member 130 by the predetermined device 300, that is, by driving the protruding block 211 provided in the device 300, so that the transfer of the material 210 can be performed.

It is conceivable that the transfer robot may be a transfer robot such as an AGV car or a walking six-axis robot.

It is contemplated that mobile carrier 200 may be, for example, a mobile carrier for storing material 210, a mobile carrier for transferring material 210, or the like.

It is conceivable that the mobile carrier 200 may be various forms of mobile carriers 200 such as a frame for profile welding, a frame for aluminum profile splicing, a frame for sheet metal welding, and the like.

Although the above-described stopper device 100 can be applied to a mobile carrier 200 without a control system or power, the present invention is not limited thereto, and the above-described stopper device 100 can be applied to a carrier having a control system or power, and in this case, the carrier can be regarded as any equipment, such as various press-fitting equipment, assembling equipment, a line, and the like.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention.
