[0040] The specific structure of a clamping device provided by an embodiment of the utility model and the corresponding technical effects brought about by it are described in detail below with reference to the patent drawings.

[0041] Please refer to Figure 1-Figure 2 , a clamping device 1 provided in an embodiment of the present invention includes a bearing assembly 100 and a side pressure assembly 200 .

[0042] The bearing assembly 100 includes a bottom plate 110, a top plate 120, a limit member 140 and a first side plate 130. The bottom plate 110 and the top plate 120 are arranged opposite to each other, the limit member 140 is connected to the bottom plate 110, the limit member 140 and the first side plate 130 are arranged at intervals and are both located between the floor and the top plate 120. The bottom plate 110, the top plate 120, the limit member 140 and the first side plate 130 jointly define an installation space 150 for clamping the plate 2. The side pressure assembly 200 includes a first connecting member and a side pressure portion 210 connected thereto. The first connecting member is connected to the first side plate 130. One end of the side pressure portion 210 is located between the first side plate 130 and the limit member 140. The other end of the side pressure portion 210 passes through the first side plate 130 and is connected to the first connecting member. The first connecting member can drive the side pressure portion 210 to approach or move away from the limit member 140.

[0043] It should be noted that the above-mentioned plate 2 includes but is not limited to a PCB board, wherein the first side panel 130 and the top panel 120 are integrally formed and abut against the bottom panel 110, and the bottom panel 110 and the end of the first side panel 130 away from the top panel 120 are detachably connected, wherein a first boss 111 is protruding toward the top panel 120 on the side of the bottom panel 110 away from the first side panel 130, and the first boss 111 is located on the side of the limit member 140 away from the first side panel 130, and a second boss 121 is protruding toward the bottom panel 110 on the side of the top panel 120 away from the first side panel 130, and the first boss 111 and the second boss 121 are detachably connected and together form a second side panel opposite to the first side panel 130. Through the above-mentioned arrangement, it is convenient for users to disassemble and assemble the clamping device 1.

[0044] Of course, in some other optional embodiments, the above-mentioned supporting assembly 100 can also be of other structural forms, as long as it has a top plate 120, a bottom plate 110, a first side plate 130 and a limiting member 140 that define the installation space 150.

[0045] When the PCB is placed on the bottom plate 110 and located between the stopper 140 and the first side plate 130, the user can place one side of the PCB in contact with the stopper 140 and move the PCB away from the first side plate 130. The side pressure portion 210 is then driven by the first connector of the side pressure assembly 200 to approach the first stopper 140, so that the side pressure portion 210 presses the PCB onto the stopper 140.

[0046] It should be noted that the side pressure portion 210 and the limiting member 140 provided in this embodiment only clamp the space on the side of the PCB board, which can effectively reduce the space occupied by the PCB board and increase the layout space on the PCB board for hardware engineers.

[0047] The detailed first connecting member includes a first screw 220 and a first connecting portion 240. The first screw 220 is passed through the first connecting portion 240 and is threadedly connected to the first side plate 130. The first screw 220 can rotate along its own axis relative to the first connecting portion 240. The end of the side pressure portion 210 away from the limiting portion is connected to the first connecting portion 240. When the first screw 220 is rotated, the first connecting portion 240 can drive the side pressure portion 210 away from or close to the limiting member 140.

[0048] Existing methods of clamping PCBs using grippers or suction cups require power output devices such as cylinders, which can be costly for small-batch development or projects in the R&D phase. In this embodiment, when the PCB is placed on the base plate 110 and positioned between the stopper 140 and the first side plate 130, manually rotating the first screw 220 moves the side pressure portion 210 closer to or further from the stopper, thereby clamping or releasing the PCB. This significantly reduces costs for small-batch development or projects in the R&D phase.

[0049] In detail, the first screw 220 is provided with a first limiting portion 230, the first limiting portion 230 is in contact with the first connecting portion 240, and the first connecting portion 240 is located between the first limiting portion 230 and the first side plate 130. That is, when the first screw 220 rotates and approaches the limiting member 140 relative to the first side plate 130, the first connecting portion 240 can be driven by the first limiting portion 230 to move in the direction close to the limiting member 140.

[0050] It should be noted that the first limiting portion 230 in this embodiment is a rod coaxially arranged with the first screw 220 , and the radial dimension of the rod is larger than the radial dimension of the first screw 220 , and one end of the rod abuts against the first connecting portion 240 .

[0051] When the first screw 220 rotates and moves relative to the first side plate 130 in a direction away from the stopper 140, in order to facilitate the return of the first connecting portion 240, the side pressure portion 210 can also be driven to move away from the stopper 140. In this embodiment, the first connecting portion further includes a first elastic member 260. The two ends of the first elastic member 260 respectively abut against the first side plate 130 and the first connecting portion 240, and the first elastic member 260 is in a compressed state. In other words, when the first screw 220 rotates and moves relative to the first side plate 130 in a direction away from the stopper 140, the first elastic member 260 applies a force to the first connecting portion 240 away from the first side plate 130, so that the first connecting portion 240 drives the side pressure portion 210 to move away from the stopper 140.

[0052] Of course, in some other optional embodiments, the first screw 220 is also provided with a second limiting portion, and the first limiting portion 230 and the second limiting portion are respectively located on both sides of the first connecting portion 240. That is to say, no matter how the first screw 220 rotates, when the first screw 220 approaches or moves away from the limiting member 140 relative to the first side plate 130, the first connecting portion 240 can be driven to move closer to or away from the limiting member 140 through the first limiting portion 230 or the second limiting portion.

[0053] Alternatively, in some other optional embodiments, one end of the first screw 220 can also be directly connected to the side pressure part 210, and the side pressure part 210 can be directly driven away from or close to the limit member 140 by the first screw 220. At this time, the side pressure part 210 can be a limit rod coaxial with the first screw 220.

[0054] In this embodiment, the side pressure portion 210 is mounted on the bottom plate 110 and can slide relative to the bottom plate 110. In order to ensure that the side pressure portion 210, driven by the first connecting portion 240, moves more stably toward or away from the limiting member 140, the first connecting member further includes a first guide rod 250. The first guide rod 250 is passed through the first connecting portion 240 and connected to the first side plate 130. The first connecting portion 240 can slide relative to the first guide rod 250. It is understandable that the first guide rod 250 cannot move relative to the first side plate 130. The first guide rod 250 can provide a certain support for the first connecting portion 240, so that the first connecting portion 240 can move more stably along the axial direction of the first guide rod 250 or the axial direction of the first screw 220.

[0055] In detail, in this embodiment, in the arrangement direction of the top plate 120 and the bottom plate 110, that is, Figure 1 In the height direction for reference, the first guide rod 250 is located between the first screw rod 220 and the side pressure portion 210. There are multiple first guide rods 250, and the multiple first guide rods 250 are arranged at intervals along a predetermined direction, wherein the predetermined direction, the arrangement direction of the bottom plate 110 and the top plate 120, and the arrangement direction of the first side plate 130 and the stopper 140 are perpendicular to each other.

[0056] In order to ensure that the first elastic member 260 can be more stably located between the first connecting portion 240 and the first side plate 130, in this embodiment, the first elastic member 260 is a spring, and the first elastic member 260 is sleeved on the first guide rod 250. In addition, the number of the first elastic members 260 is the same as the number of the first guide rods 250, and multiple first elastic members 260 are correspondingly sleeved on the first guide rod 250.

[0057] Optionally, in some other embodiments, the first elastic member 260 can also be sleeved on the first screw 220, or the first elastic member 260 can be sleeved on the side pressure portion 210. As long as it can be ensured that the two ends of the first elastic member 260 are respectively in contact with the first side plate 130 and the first connecting portion 240 and are in a compressed state, the first elastic member 260 can ensure the reset of the first connecting portion 240.

[0058] In this embodiment, in order to more stably clamp the PCB board located in the installation space 150, the clamping device 1 also includes a pressing assembly 300, which includes a second connecting member and a pressing portion 310 connected to each other. The second connecting member is connected to the top plate 120, and one end of the pressing portion 310 is located between the top plate 120 and the bottom plate 110. The other end of the pressing portion 310 is connected to the second connecting member, and the second connecting member can drive the pressing portion 310 to move closer to or away from the bottom plate 110.

[0059] In detail, the top pressing assembly 300 includes two groups of top pressing parts 310, and the two groups of top pressing parts 310 are arranged at intervals along the arrangement direction of the limiter 140 and the first side plate 130. One of the two groups of top pressing parts 310 at least partially overlaps with the limiter in a preset direction, and the preset direction is perpendicular to the arrangement direction of the limiter 140 and the first side plate 130. That is, the group of top pressing parts 310 that at least partially overlaps with the limiter in the preset direction is pressed on the edge of the PCB board during the pressing process. The two groups of top pressing parts 310 They are respectively used to press the two ends of the plate 2. That is to say, when pressing the PCB board, in the arrangement direction of the limit member 140 and the first side plate 130, the two groups of top pressing parts 310 are respectively used to press the two ends of the PCB board. That is to say, the two groups of top pressing parts 310 can improve the stability of clamping the PCB board and will not occupy too much space on the side of the PCB board close to the top plate 120. That is to say, more space can be placed on the PCB board for electronic components, which increases the layout space on the PCB board for hardware engineers.

[0060] In detail, in this embodiment, each group of pressing parts 310 has two pressing parts 310, and the two pressing parts 310 in each group are arranged at intervals along a preset direction, thereby effectively improving the clamping stability of the pressing assembly 300 on the PCB.

[0061] Furthermore, the second connecting member includes a second screw 320 and a second connecting portion 340. The end of the pressing portion 310 away from the bottom plate 110 is connected to the second connecting portion 340. The second screw 320 passes through the second connecting portion 340 and is threadedly connected to the top plate 120. That is, in the process of screwing the second screw 320, the second screw 320 can move relative to the top plate 120 along its own axis. The second screw 320 can rotate the second connecting portion 340 along its own axis. When the second screw 320 rotates, the second connecting portion 340 can drive the pressing portion 310 away from or close to the bottom plate 110.

[0062] In some existing systems, when clamping PCBs with grippers or suction cups, power output devices such as cylinders are required, but this is costly for small-batch development or projects in the R&D stage.

[0063] In this embodiment, when clamping the PCB board, the PCB board is placed on the base plate 110 and located between the limiter 140 and the first side plate 130. By rotating the first screw 220, the side pressure portion 210 can be moved closer to or away from the limiter. The second screw 320 can be manually rotated to move the top pressure portion 310 closer to or away from the base plate 110, thereby clamping or releasing the PCB board. This can avoid the use of power output equipment such as cylinders, effectively saving costs for small-batch development or projects in the R&D stage.

[0064] The second screw 320 is provided with a third stopper 330. The third stopper 330 abuts against the second connection portion 340, and the second connection portion 340 is located between the third stopper 330 and the top plate 120. In other words, when the second screw 320 rotates and moves closer to the bottom plate 110 relative to the top plate 120, the third stopper 330 can drive the second connection portion 340 to move closer to the bottom plate 110.

[0065] It should be noted that the third limiting portion 330 in this embodiment is also a rod coaxially arranged with the second screw 320 , and the radial dimension of the rod is larger than the radial dimension of the second screw 320 , and one end of the rod abuts against the second connecting portion 340 .

[0066] When the second screw 320 rotates and moves relative to the top plate 120 in a direction away from the bottom plate 110, in order to facilitate the return of the second connecting portion 340, it can also drive the pressing portion 310 to move away from the bottom plate 110. In this embodiment, the second connecting member further includes a second elastic member 360. The two ends of the second elastic member 360 respectively abut against the top plate 120 and the second connecting portion 340, and the second elastic member 360 is in a compressed state. In other words, when the second screw 320 rotates and moves relative to the top plate 120 in a direction away from the bottom plate 110, the second elastic member 360 will apply a force to the second connecting portion 340 away from the top plate 120, so that the second connecting portion 340 drives the pressing portion 310 to move away from the bottom plate 110.

[0067] Of course, in some other optional embodiments, the second screw 320 is also provided with a fourth limiting portion, and the third limiting portion 330 and the fourth limiting portion are respectively located on both sides of the second connecting portion 340. That is to say, no matter how the second screw 320 rotates, when the second screw 320 is close to or away from the bottom plate 110 relative to the top plate 120, the second connecting portion 340 can be driven to move closer to or away from the bottom plate 110 through the third limiting portion 330 or the fourth limiting portion.

[0068] Alternatively, in some other optional embodiments, one end of the second screw 320 can also be directly connected to the pressing part 310, and the second screw 320 can directly drive the pressing part 310 away from or close to the limiting member 140. At this time, the pressing part 310 can be a limiting rod coaxial with the second screw 320.

[0069] In order to ensure that the top pressure part 310 moves more stably toward or away from the bottom plate 110 under the drive of the second connecting part 340, the second connecting member also includes a second guide rod 350, which is passed through the second connecting part 340 and is connected to the top plate 120. The second connecting part 340 can slide relative to the second guide rod 350. It can be understood that the second guide rod 350 cannot move relative to the top plate 120. The second guide rod 350 can play a certain supporting role for the second connecting part 340, so that the second connecting part 340 can move more stably along the axial direction of the second guide rod 350 or the axial direction of the second screw 320.

[0070] It should be noted that the second guide rod 350 is a linear bearing. Of course, in other optional embodiments, the second guide rod 350 can also be a common rod structure.

[0071] In detail, in this embodiment, in the arrangement direction of the limiting member 140 and the first side plate 130 , there are two second guide rods 350 , which are arranged at intervals.

[0072] In order to ensure that the second elastic member 360 can be more stably located between the second connecting portion 340 and the top plate 120, in this embodiment, the second elastic member 360 is a spring, and the second elastic member 360 is sleeved on the top pressing portion 310. In addition, the number of the second elastic members 360 is the same as the number of the top pressing portions 310, and multiple second elastic members 360 are correspondingly sleeved on the top pressing portions 310. It should be noted that the top pressing portion 310 is a rod structure.

[0073] Optionally, in some other embodiments, the second elastic member 360 can also be sleeved on the second screw 320, or the second elastic member 360 can be sleeved on the second guide rod 350. As long as it can be ensured that the two ends of the second elastic member 360 are respectively in contact with the top plate 120 and the second connecting portion 340 and are in a compressed state, the second elastic member 360 can ensure the reset of the second connecting portion 340.

[0074] It should be noted that in this embodiment, the first connecting portion 240 is a plate-shaped structure opposite to the first side plate 130, and the second connecting portion 340 is a plate-shaped structure opposite to the top plate 120. The limiting member 140 is a limiting column, and the number of the limiting columns is two and they are spaced apart and arranged on the bottom plate 110 along a preset direction.

[0075] In summary, the embodiment of the present invention provides a clamping device 1 including a bearing assembly 100 and a side pressure assembly 200 .
