[0058] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0059] like Figures 1 to 7 As shown, an embodiment of the present invention provides a connecting device 100, including a frame 1, a material box 6, a feeding mechanism 2 and a rotating mechanism 3; the rotating mechanism 3 and the feeding mechanism 2 are mounted on the material box support 11, the material box 6 is disposed on the rotating mechanism 3, and the rotating mechanism 3 is used to drive the material box to rotate.

[0060] The magazine 6 has an opening through which the material plate can enter or exit the magazine 6. The rotating mechanism 3 can drive the magazine 6 to rotate so as to switch the magazine 6 between the first position and the second position. When the magazine 6 is in the first position, the opening faces the feeding mechanism 2, and when the magazine 6 is in the second position, the opening faces away from the feeding mechanism 2. By driving the magazine 6 to rotate through the rotating mechanism 3, the opening of the magazine 6 can face the feeding mechanism 2 or face away from the feeding mechanism 2, so that the magazine 6 can be used as a connection point between different processes, and by changing the direction of the opening of the magazine 6, the direction of the material plate can be adjusted, ensuring that the direction of the material plate entering or exiting each process is consistent, which helps to realize the orderly flow of materials between different processes without manually adjusting the direction of the material plate.

[0061] In the first position, the feeding mechanism 2 can drive the material plate to move in the first direction a so that the material plate can enter or exit the magazine 6 through the opening, that is, in the first position, the feeding mechanism 2 can store the material plate in the magazine or send the material plate out of the magazine 6 through the opening. In the second position, the magazine 6 is configured to move into or out of the rack 1, and the magazine 6 can be transferred to the next process or from the previous process to the rack 1.

[0062] In the embodiment, when the rotating mechanism 3 drives the magazine 6 to rotate so that the opening of the magazine 6 faces the feeding mechanism 2, the feeding mechanism 2 can smoothly input or output the material plate into or out of the magazine 6 through the opening, which is conducive to realizing the automatic feeding and discharging operation of the magazine 6. When the opening of the magazine 6 faces away from the feeding mechanism 2, it is convenient to unload the magazine. By cooperating the feeding mechanism 2 with the rotating mechanism 3, the processes of feeding, material plate entering or exiting the magazine, and magazine loading and unloading can be realized, and thus the automatic connection between different processes can be realized.

[0063] In an embodiment, in the field of PCB production, the connection device 100 can be used in the upper PIN process and the lower PIN process. Specifically, in the upper PIN process, the connection device 100 is arranged between the upper PIN machine and a carrying device, such as a carrying robot. After the upper PIN operation of the material plate is completed, the rotating mechanism 3 drives the magazine 6 to rotate so that the opening of the magazine 6 faces the feeding mechanism 2, and the feeding mechanism 2 sends the material plate on which the upper PIN operation is completed into the magazine. After the magazine 6 is fully loaded, the rotating mechanism 3 drives the magazine 6 to rotate so that the opening of the magazine 6 faces away from the feeding mechanism 2, so as to adjust the direction of the material plate. At this time, the magazine 6 can be taken away by the carrying device, so that the magazine 6 leaves the rack 1. When the carrying device carries the magazine 6 to the next process, the material plate can enter the next process in the correct direction without the need for manual adjustment, thereby realizing the automatic connection between the upper PIN process and the carrying device.

[0064] When the next PIN process is performed, the connecting device 100 is arranged between the next PIN machine and the carrying device. The carrying device carries the box to the rack 1, and the box is rotated by the rotating mechanism 3 so that the opening of the box faces the feeding mechanism 2. The direction of the board is adjusted so that the feeding mechanism 2 can send the board in the box to the next PIN machine, and the next PIN machine performs the next PIN operation on the board. After the box is empty, the rotating mechanism 3 rotates the box so that the opening of the box faces away from the feeding mechanism 2. The empty box is taken away by the carrying device. After the box is fully loaded again, the above operation is repeated, thereby realizing the automatic connection between the next PIN machine and the carrying device.

[0065] In an embodiment, as shown in Figure 2 The feeding mechanism 2 includes a support frame 21, a first driving member 22, and a clamping member 23. One end of the support frame 21 is connected to the rack 1, and the other end of the support frame 21 extends away from the rack 1 along the first direction a. The support frame 21 is a cantilever structure, and the feeding mechanism 2 is connected to the rack 1 through the support frame 21. The clamping member 23 is used to clamp the board, and the first driving member 22 can drive the clamping member 23 to move along the first direction a to drive the board to move along the first direction a. The board is stably clamped by the clamping member 23, and the clamping member 23 is driven to move under the driving of the first driving member 22, thereby stably sending the board into or out of the box 6.

[0066] In an embodiment, as shown in Figure 2 The support frame 21 includes two frame bodies 211, and the clamping member 23 is slidingly connected between the two frame bodies 211. The first driving member 22 is installed on at least one of the two frame bodies 211, and the first driving member 22 can drive the clamping member 23 to move along the first direction a between the two frame bodies 211. When the clamping member 23 drives the board to move, the two frame bodies 211 jointly bear the weight of the clamping member 23 and the board. The first driving member 22 can be provided with one or two. When the first driving member 22 is provided with one, the first driving member 22 is installed on one of the frame bodies 211, and one first driving member 22 drives the clamping member 23. When the first driving member 22 is provided with two, one first driving member 22 is installed on each frame body 211, and the two first driving members 22 jointly drive the clamping member 23.

[0067] Preferably, the size of the frame body 211 in the vertical direction gradually increases along the direction of the first direction a toward the rack 1, thereby forming stable support.

[0068] In an embodiment, as shown in Figure 3As shown, the first driving member 22 comprises a driving motor 221, a driving wheel 222, a driven wheel 223 and a synchronous belt 224, the driving motor 221 is fixedly installed on the frame body 211, the output end of the driving motor 221 is connected with the driving wheel 222, the driven wheel 223 is installed on the frame body 211 of the support frame 21, and the synchronous belt 224 is wound on the driving wheel 222 and the driven wheel 223. The driving motor 221 can drive the driving wheel 222 to rotate and drive the synchronous belt 224 to transmit power. The synchronous belt 224 is connected with the clamping member 23, and the clamping member 23 is slidably connected between the two frame bodies 211. Under the driving of the driving motor 221, the clamping member 23 can move in the first direction a.

[0069] In an embodiment, as shown in Figure 3 , Figure 4 As shown, the clamping member 23 comprises a transition plate 231, a second driving member 232 and a clamping jaw 233, the transition plate 231 is slidably connected to the support frame 21, and the output end of the first driving member 22 is connected to the transition plate 231. The transition plate 231 is slidably connected between the two frame bodies 211 through a linear guide rail, and the first driving member 22 directly drives the transition plate 231 to slide relative to the two frame bodies 211, thereby realizing the sliding of the clamping member 23 relative to the two frame bodies 211.

[0070] The second driving member 232 is connected with the transition plate 231, and the second driving member 232 can drive the clamping jaw 233 to release or clamp the material plate. The second driving member 232 can drive the clamping jaw 233 to open or close, and the clamping jaw 233 can release the material plate when it is open, and clamp the material plate when it is closed.

[0071] In an embodiment, as shown in Figure 3 , Figure 4 As shown, the clamping jaw 233 comprises a first clamping jaw 2331 and a second clamping jaw 2332, the first clamping jaw 2331 is rotatably connected with the second clamping jaw 2332, the output end of the second driving member 232 is connected with the first clamping jaw 2331, and the second clamping jaw 2332 is fixedly arranged relative to the transition plate 231. Through the driving of the second driving member 232 on the first clamping jaw 2331, the first clamping jaw 2331 can be driven to rotate relative to the second clamping jaw 2332, the opening and closing degree of the clamping jaw 233 is accurately controlled, and the clamping jaw 233 releases or clamps the material plate.

[0072] Specifically, when the second driving member 232 drives the first jaw 2331 to rotate, the included angle between the first jaw 2331 and the second jaw 2332 changes. When the included angle between the first jaw 2331 and the second jaw 2332 gradually decreases, the jaw 233 gradually closes, thereby generating a clamping force on the material plate between the first jaw 2331 and the second jaw 2332, forming a stable clamping of the material plate. When the included angle between the first jaw 2331 and the second jaw 2332 gradually increases, the jaw 233 gradually opens, thereby releasing the clamping of the material plate.

[0073] In other alternative embodiments, the output end of the second driving member 232 is connected with the second jaw 2332, and through the driving of the second jaw 2332 by the second driving member 232, the relative rotation between the first jaw 2331 and the second jaw 2332 can be driven, or the second driving member 232 includes two sub-driving members, one of which is connected with the first jaw 2331, and the other of which is connected with the second jaw 2332, and through the driving of the two sub-driving members, the relative rotation between the first jaw 2331 and the second jaw 2332 can be realized.

[0074] In an embodiment, as shown in Figure 3 , Figure 4 The first jaw 2331 includes a first connecting portion 23311 and a first clamping portion 23312, the first clamping portion 23312 is installed at one end of the first connecting portion 23311 away from the transition plate 231, the second jaw 2332 includes a second connecting portion 23321 and a second clamping portion 23322, the second connecting portion 23321 is installed on the transition plate 231, the second driving member 232 is installed on the second connecting portion 23321, and the second clamping portion 23322 is installed at one end of the second connecting portion 23321 away from the transition plate 231.

[0075] The first connecting portion 23311 and the second connecting portion 23321 are rotationally connected, the output end of the second driving member 232 is connected with one end of the first connecting portion 23311 close to the transition plate 231, and the second driving member 232 drives the first connecting portion 23311 to rotate relative to the second connecting portion 23321, thereby driving the first clamping portion 23312 to approach or move away from the second clamping portion 23322 to clamp or release the material plate.

[0076] When the second driving member 232 is activated, power is transmitted to the first connecting part 23311 near the end of the transition plate 231, so that the first connecting part 23311 rotates around the rotation connecting point with the second connecting part 23321, and the rotation of the first connecting part 23311 drives the first clamping part 23312 to move accordingly, so as to adjust the opening and closing range between the first clamping part 23312 and the second clamping part 23322. When the first clamping part 23312 is close to the second clamping part 23322, the material plate is clamped between the first clamping part 23312 and the second clamping part 23322. When the first clamping part 23312 is away from the second clamping part 23322, the material plate is released.

[0077] It can be understood that the output end of the second driving member 232 is rotationally connected with the first connecting part 23311.

[0078] Preferably, the second driving member 232 is a pneumatic cylinder, and the second driving member 232 can drive the first connecting part 23311 to move up and down near the end of the transition plate 231, and the rotation connecting point of the first connecting part 23311 and the second connecting part 23321 is equivalent to a fulcrum, so that the first clamping part 23312 away from the end of the transition plate 231 can also move up and down. When the second driving member 232 drives the first connecting part 23311 to move downward near the end of the transition plate 231, the first clamping part 23312 moves upward, so that the first clamping part 23312 is away from the second clamping part 23322, and the material plate is released. When the second driving member 232 drives the first connecting part 23311 to move upward near the end of the transition plate 231, the first clamping part 23312 moves downward, so that the first clamping part 23312 is close to the second clamping part 23322, and the clamping of the material plate is achieved.

[0079] The position of the rotation connecting point of the first connecting part 23311 and the second connecting part 23321 is determined according to the required opening and closing range between the first clamping part 23312 and the second clamping part 23322.

[0080] In an embodiment, the second connecting part 23321 has an L-shaped structure with a horizontal segment and a vertical segment connected with each other, the vertical segment is connected with the transition plate 231, and the second driving member 232 is installed on the vertical segment. The horizontal segment is rotationally connected with the first connecting part 23311.

[0081] In an embodiment, as shown in Figure 2 The feeding mechanism 2 further includes a material receiving assembly 24 installed on the support frame 21, and the material receiving assembly 24 is used to receive the material plate and drive the material plate to move along the first direction a towards the clamping member 23, so that the clamping member 23 can clamp the material plate. By driving the material plate to move through the material receiving assembly 24, the material plate can be moved to the clamping range of the clamping member 23, and the clamping member 23 can clamp the material plate.

[0082] As an example, the feeding mechanism 2 comprises a receiving assembly 24, a support frame 21, a first driving member 22 and a clamping member 23, the receiving assembly 24 is installed on the support frame 21. When the moving stroke of the first driving member 22 is insufficient or the clamping member 23 is inconvenient to clamp, the material plate is sent to the receiving assembly 24, the receiving assembly 24 can drive the material plate to move in the first direction a, so that the material plate moves to a position where the clamping member 23 can clamp, compensates for the insufficient stroke of the first driving member 22, and facilitates clamping by the clamping member 23. Then, the first driving member 22 drives the clamping member 23 to continue moving in the first direction a, and sends the material plate into or out of the hopper 6.

[0083] In an embodiment, as shown in Figure 3 、 Figure 4 The clamping member 23 further comprises a third driving member 234, the third driving member 234 is installed on the transition plate 231, and the third driving member 234 can drive the clamping jaw 233 to move in the second direction b to avoid collision when the receiving assembly 24 drives the material plate to move in the first direction a, so as to ensure that the material plate and the clamping jaw 233 will not collide and interfere with each other, reduce damage to the material, and ensure smooth operation of the material plate during conveying and clamping.
