The toggle lever is rotatably connected to the first clamping member. One end of the toggle lever is connected to the output end of the second driving member, and the other end of the toggle lever is connected to the second clamping member. The second driving member drives the toggle lever to rotate, thereby causing the second clamping member to reciprocate along a second direction to clamp the material plate between the first clamping member and the second clamping member or to release the material plate.

[0007] The first direction and the second direction are not parallel and do not coincide.

[0008] Optionally, the actuating lever includes a rotating part, a first rod body, and a second rod body. The first clamping member is provided with a first mounting groove. The rotating part is disposed in the first mounting groove and is rotatably connected to the first clamping member.

[0011] When the lever is rotated, the second clamping member moves in the second mounting groove along the second direction.

[0012] Optionally, the second clamping member includes a jaw connecting portion and a jaw, the jaw connecting portion passing through the second mounting groove, and the jaw connected to the end of the jaw connecting portion away from the first clamping member;

[0013] When the second clamping member reciprocates along the second direction, the gripper can move closer to or further away from the first clamping member.

[0014] Optionally, the first clamping member is provided with an anti-slip pad, which is used to adhere to the material plate when the first clamping member and the second clamping member clamp the material plate.

[0015] Optionally, the clamping mechanism further includes a connector and a guide block. The connector is connected between the output end of the second driving member and the actuating rod. The guide block is installed on the first clamping member and has a guide groove. The connector passes through the guide groove, and the guide groove is used to guide the movement of the connector when the second driving member drives the actuating rod to rotate.

[0016] Optionally, the clamping mechanism further includes an infeed sensor and an outfeed sensor, which are mounted on the first clamping member; the infeed sensor is used to detect the position of the material plate when it enters the hopper, and the outfeed sensor is used to detect the position of the material plate when it leaves the hopper.

[0017] Optionally, the hopper includes a frame and a plurality of support frames disposed on the frame, the plurality of support frames being spaced apart along the second direction, and each support frame being provided with a plurality of workstations;

[0022] The transfer device provided in this embodiment of the utility model, under the drive of the second driving member, moves one end of the toggle lever with the output end of the second driving member, so that the toggle lever can rotate around its connection point with the first clamping member, thereby driving the second clamping member to reciprocate along the second direction, so that the second clamping member can approach or move away from the first clamping member in the second direction, thereby realizing the clamping or releasing operation of the material plate.

[0023] By mounting the clamping mechanism on the connecting frame, the clamping mechanism can grab or release the material plate. When the connecting frame reciprocates along the first direction under the drive of the first driving component, the clamping mechanism mounted on the connecting frame will also move synchronously with the connecting frame, thereby driving the material plate to move in the first direction. That is, as long as the smooth movement of the connecting frame and the reliable operation of the clamping mechanism are ensured, the material plate movement operation can be completed. This eliminates the need to arrange many additional dispersed moving parts inside the hopper, fundamentally reducing the number of moving parts in the hopper, making the structure of the transfer device simpler, simplifying the assembly process and reducing production costs.

[0033] 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.

[0034] like Figures 1 to 4 As shown, an embodiment of this utility model provides a transfer device including a hopper 1, a conveying mechanism 2, and a clamping mechanism 3. The hopper 1 is used to store material plates. The conveying mechanism 2 includes a first driving member 21 and a connecting frame 22. The clamping mechanism 3 is mounted on the connecting frame 22. The first driving member 21 can drive the connecting frame 22 and the clamping mechanism 3 to move along a first direction a, so as to drive the material plates to enter and exit the hopper 1 along the first direction a.

[0035] The clamping mechanism 3 is mounted on the connecting frame 22. After the clamping mechanism 3 clamps the material plate, when the first driving member 21 drives the connecting frame 22 to move, the clamping mechanism 3 on the connecting frame 22 moves together, thereby moving the material plate in the hopper 1. The clamping mechanism 3 can reliably clamp the material plate, ensuring that the material plate will not slip or deviate when moving in and out of the hopper 1 with the connecting frame 22. The connecting frame 22 extends along a third direction c and is mounted on the hopper 1.

[0036] like Figure 2As shown, the clamping mechanism 3 includes a second driving member 31, a toggle lever 32, a first clamping member 33, and a second clamping member 34. The second driving member 31 and the first clamping member 33 are mounted on the connecting frame 22. The toggle lever 32 is rotatably connected to the first clamping member 33. One end of the toggle lever 32 is connected to the output end of the second driving member 31, and the other end of the toggle lever 32 is connected to the second clamping member 34. The second driving member 31 drives the toggle lever 32 to rotate, which can drive the second clamping member 34 to reciprocate along the second direction b, so as to clamp the material plate between the first clamping member 33 and the second clamping member 34 or release the material plate. The first direction a and the second direction b are not parallel and do not coincide.

[0037] The actuating lever 32 connects the second driving member 31 with the first clamping member 33 and the second clamping member 34. One end of the actuating lever 32 is connected to the output end of the second driving member 31, and the other end is connected to the second clamping member 34, forming a lever-like structure. Driven by the second driving member 31, one end of the actuating lever 32 moves with the output end of the second driving member 31, allowing the actuating lever 32 to rotate around its connection point with the first clamping member 33. This causes the second clamping member 34 to reciprocate along the second direction b, allowing the second clamping member 34 to move closer to or further away from the first clamping member 33 in the second direction b, thereby achieving the clamping or releasing operation of the material plate.

[0038] There is a clamping space between the first clamping member 33 and the second clamping member 34. When the material plate enters the clamping space, the second clamping member 34 moves closer to the first clamping member 33 and clamps the material plate. When the second clamping member 34 moves away from the first clamping member 33, the material plate is released and can leave the clamping space.

[0039] Among them, the first direction a, the second direction b, and the third direction c are perpendicular to each other in each other. The first direction a is the direction in which the material plate enters and exits the material bin 1 on the horizontal plane. The second direction b is the vertical direction. The third direction c is the direction in which the material plate enters and exits the material bin 1 on the horizontal plane.

[0040] The second driving component 31 serves as the power source for the entire clamping mechanism 3, providing power support for the clamping and releasing actions of the material plate. It can employ various driving methods, commonly including electric drive and pneumatic drive. Preferably, the second driving component 31 is a cylinder or an electric push rod. The output end of the second driving component 31 can move along a third direction c. Through the rotational connection of the lever 32 on the first clamping component 33, the movement of the output end of the second driving component 31 in the third direction c is converted into the movement of the second clamping component 34 in the second direction b. This design, which converts movements in different directions, enables complex material plate clamping functions within a relatively limited space. It avoids the need for a separate linear drive mechanism for the movement of the second clamping component 34 in the second direction b, making the entire clamping mechanism 3 more compact and occupying less space in the transfer device, thus contributing to the overall miniaturization and layout optimization of the transfer device.

[0041] In this embodiment, by setting the clamping mechanism 3 on the connecting frame 22, the clamping mechanism 3 can grasp or release the material plate. When the connecting frame 22 moves back and forth along the first direction a under the drive of the first driving member 21, the clamping mechanism 3 installed on the connecting frame 22 will also move synchronously with the connecting frame 22, thereby driving the material plate to move in the first direction a. That is, as long as the smooth movement of the connecting frame 22 and the reliable operation of the clamping mechanism 3 are ensured, the material plate movement operation can be completed. This eliminates the need to arrange more dispersed moving parts inside the hopper 1, fundamentally reducing the number of moving parts inside the hopper 1, making the structure of the transfer device simpler, simplifying the assembly process and reducing production costs.

[0042] In one embodiment, such as Figure 2 , Figure 3 As shown, the actuating lever 32 includes a rotating part 321, a first lever body 322, and a second lever body 323. A first mounting groove 331 is provided on the first clamping member 33. The rotating part 321 is disposed in the first mounting groove 331 and rotatably connected to the first clamping member 33, thus confining the rotating part 321 in the first mounting groove 331. Under the drive of the second driving member 31, the rotating part 321 can rotate around an axis in the first mounting groove 331, providing a stable and defined rotation fulcrum for the movement of the entire actuating lever 32.

[0043] One end of the first rod 322 is connected to the rotating part 321, and the other end of the first rod 322 is connected to the output end of the second drive member 31. One end of the second rod 323 is connected to the rotating part 321, and the other end of the second rod 323 is connected to the second clamping member 34. The rotating part 321 connects the first rod 322 and the second rod 323 together. Through the rotational connection between the rotating part 321 and the first clamping member 33, a stable and reliable motion transmission is provided. The power output by the second drive member 31 can be accurately transmitted to the rotating part 321 through the first rod 322. Then, through the rotation of the rotating part 321, the second rod 323 stably converts the rotational motion into the linear motion of the second clamping member 34, thereby realizing the stable clamping and releasing operation of the material plate.

[0044] In the initial state, the output end of the second drive member 31 is in the extended state, the second clamping member 34 is in the lowered state, and the distance between the second clamping member 34 and the first clamping member 33 is large. After the material plate enters the clamping space, the output end of the second drive member 31 retracts, the second clamping member 34 retracts, the clamping space decreases, and the material plate is clamped.

[0045] In one embodiment, such as Figure 3 As shown, the lever 32 is rotatably connected to the first clamping member 33 via a rotating shaft. The rotating shaft extends along the first direction a and is located in the first mounting groove 331. The central axis of the rotating shaft coincides with the axis of rotation of the lever 32, so that under the drive of the second driving member 31, the lever 32 can only rotate around the rotating shaft.

[0046] In one embodiment, such as Figure 3 As shown, the extension directions of the first rod 322 and the second rod 323 are not on the same straight line, and the actuating rod 32 has a V-shaped structure. Preferably, the included angle between the first rod 322 and the second rod 323 is an acute angle.

[0047] In one embodiment, such as Figure 2 , Figure 3 As shown, the first clamping member 33 is also provided with a second mounting groove 332. The first mounting groove 331 and the second mounting groove 332 are interconnected. One end of the second clamping member 34 is disposed in the second mounting groove 332 and connected to the second rod body 323. When the actuating rod 32 rotates, the second clamping member 34 moves in the second mounting groove 332 along the second direction b.

[0048] The second mounting groove 332 extends through the first clamping member 33 along the second direction b. When the actuating lever 32 starts to rotate under the drive of the second driving member 31, the second rod 323 can rotate around the rotating part 321. Since one end of the second clamping member 34 is connected to the second rod 323 and is confined in the second mounting groove 332, the rotation of the second rod 323 can be converted into a linear reciprocating motion of the second clamping member 34 along the second direction b within the second mounting groove 332. In this embodiment, the second mounting groove 332 provides precise guidance for the movement of the second clamping member 34, preventing unnecessary lateral offset or swaying of the second clamping member 34 during movement.

[0049] In one embodiment, such as Figure 2 , Figure 3 As shown, the second clamping member 34 includes a jaw connecting part 341 and a jaw 342. The jaw connecting part 341 passes through the second mounting groove 332. The shape and size of the jaw connecting part 341 are adapted to the second mounting groove 332. The jaw 342 is connected to the end of the jaw connecting part 341 away from the first clamping member 33.

[0050] When the second clamping member 34 reciprocates along the second direction b, the gripper 342 can move closer to or further away from the first clamping member 33. Through the precise movement of the gripper connecting part 341 within the second mounting groove 332, the relative position between the gripper 342 and the first clamping member 33 can be precisely controlled, thereby achieving precise adjustment of the clamping force and position of the material plate. This effectively adapts to material plates of different thicknesses and materials, ensuring that the material plate can be stably clamped.

[0051] Specifically, when the second clamping member 34 moves towards the first clamping member 33 along the second direction b under the action of the actuating rod 32, the jaw connecting part 341 moves synchronously within the second mounting groove 332, causing the jaw 342 to gradually approach the first clamping member 33. During the continuous movement, the jaw 342 applies a suitable clamping force to the material plate, tightly clamping the material plate between the jaw 342 and the first clamping member 33, completing the clamping action of the material plate. When it is necessary to release the material plate, the second clamping member 34 moves away from the first clamping member 33 along the second direction b under the action of the actuating rod 32, and the jaw connecting part 341 moves in the opposite direction within the second mounting groove 332, causing the jaw 342 to gradually move away from the material plate, releasing the clamping force on the material plate.

[0052] In one embodiment, such as Figure 2 As shown, the gripper 342 includes a first gripping part and a second gripping part, which are disposed on opposite sides of the gripper connecting part 341 in a first direction a.

[0053] In the first direction a, the opposite two edges of the material plate are respectively designated as the first edge and the second edge. During feeding, the first driving member 21 drives the connecting frame 22 to move until the first edge of the material plate enters the clamping space. Then, the second driving member 31 drives the second clamping member 34 to move upward along the second direction b, causing the gripper 342 to gradually approach the first clamping member 33. The material plate is then clamped between the first clamping part and the lower surface of the first clamping member 33. Next, the first driving member 21 drives the connecting frame 22 to move in the opposite direction, pulling the material plate under the clamping of the first clamping part and the first clamping member 33, causing the material plate to enter the hopper 1.

[0054] When the material plate is discharged from the hopper 1, the second drive member 31 drives the second clamping member 34 to move upward along the second direction b, clamping the first edge of the material plate between the first clamping part and the lower surface of the first clamping member 33. Then, the first drive member 21 drives the connecting frame 22 to move, pulling a portion of the material plate out of the hopper 1. After that, the first drive member 21 drives the connecting frame 22 to move in the opposite direction, so that the connecting frame 22 moves to the other side of the material plate. When the second edge of the material plate enters the clamping space, after the material plate is clamped between the second clamping part and the lower surface of the first clamping member 33, the material plate can be moved during the movement of the connecting frame 22. Alternatively, after the second edge of the material plate enters the clamping space, the second edge of the material plate abuts against the jaw connecting part 341, so that as the connecting frame 22 moves, the jaw connecting part 341 pushes the material plate to move, sending the material plate out of the hopper 1.

[0055] In one embodiment, both the first clamping part and the second clamping part are provided with anti-slip teeth to increase the friction between the gripper 342 and the material plate and prevent the material plate from detaching from the gripper 342.

[0056] In one embodiment, such as Figure 2 , Figure 3 As shown, the first clamping member 33 is provided with an anti-slip pad 35. The anti-slip pad 35 is used to adhere to the material plate when the first clamping member 33 and the second clamping member 34 clamp the material plate. It can increase the friction between the first clamping member 33 and the material plate and improve the clamping stability of the material plate between the first clamping member 33 and the second clamping member 34.

[0057] In one embodiment, such as Figure 2 , Figure 3As shown, the clamping mechanism 3 also includes a connector 36 and a guide block 37. The connector 36 connects the output end of the second driving member 31 and the actuating lever 32, thus connecting the output end of the second driving member 31 to the actuating lever 32. The connector 36 and the actuating lever 32 are movably connected. The guide block 37 is mounted on the first clamping member 33 and has a guide groove 371. The connector 36 passes through the guide groove 371, which guides the movement of the connector 36 when the second driving member 31 drives the actuating lever 32 to rotate. When the second driving member 31 drives the actuating lever 32 to rotate via the connector 36, the guide groove 371 restricts the connector 36 to move only in its set direction, thus constraining and guiding the movement of the connector 36 and preventing unnecessary lateral displacement or swaying of the connector 36 due to various external forces.

[0058] In one embodiment, such as Figure 2 As shown, the clamping mechanism 3 also includes an infeed sensor 38 and an outfeed sensor 39, which are mounted on the first clamping member 33. The infeed sensor 38 is used to detect the position of the material plate when it enters the hopper 1, and the outfeed sensor 39 is used to detect the position of the material plate when it leaves the hopper 1. The infeed sensor 38 and the outfeed sensor 39 enable real-time monitoring of the material plate position, thereby allowing for precise control of the clamping mechanism 3 and the conveying mechanism 2.

[0059] The feed sensor 38 and the discharge sensor 39 typically use photoelectric induction, electromagnetic induction, or other sensing principles to detect the position of the material board. Taking photoelectric induction as an example, when the material board gradually approaches the clamping space between the first clamping member 33 and the second clamping member 34, it enters the detection area of ​​the feed sensor 38. Once the light is blocked, the feed sensor 38 sends a positioning signal, and the second driving member 31 drives the actuating rod 32 to rotate, thereby clamping the material board and pulling it into the hopper 1 under the action of the connecting frame 22. Similarly, during discharge, when the material board enters the detection area of ​​the discharge sensor 39, once the light is blocked, the discharge sensor 39 sends a positioning signal. After the first clamping member 33 and the second clamping member 34 clamp the material board, the connecting frame 22 begins to move, sending the material board out of the hopper 1.

[0060] In one embodiment, as shown in the figure, the hopper 1 includes a frame 11 and a plurality of support frames 12 disposed on the frame 11. The plurality of support frames 12 are spaced apart along the second direction b. Each support frame 12 is provided with a plurality of workstations, and each workstation can place a material plate.

[0061] Multiple clamping mechanisms 3 are provided, and the material plate at each station is clamped by at least two clamping mechanisms 3, which enhances the clamping stability of the material plate at each station, ensures the position accuracy of the material plate when entering and leaving the material bin 1 and when transferring between different processing equipment, provides reliable material plate status guarantee for subsequent processing processes, and helps to improve the processing quality and yield of products.

[0062] Specifically, when the feed sensor 38 of all clamping mechanisms 3 corresponding to each workstation senses the material plate, the second drive member 31 of all clamping mechanisms 3 is activated, causing the second clamping member 34 to approach the first clamping member 33 and clamp the material plate.

[0063] In one embodiment, in order to realize the conveying of the loading plate of each support frame 12, a lifting mechanism can be set up. After the clamping mechanism 3 and the conveying mechanism 2 have completed the conveying of the loading plate of the previous support frame 12, the connecting frame 22 is moved to the lifting mechanism. The lifting mechanism drives the connecting frame 22 to move up and down, so that the conveying mechanism 2 and the clamping mechanism 3 can be sent to the support frames 12 of different layers, thereby realizing the conveying of the loading plates of different support frames 12.

[0064] In one embodiment, such as Figure 1 , Figure 4 As shown, the first driving component 21 includes a motor 211, a first gear 212, a second gear, and a transmission rod 213. The motor 211 is mounted on the connecting frame 22, and the output end of the motor 211 is connected to the first gear 212. The first gear 212 and the second gear are mounted at both ends of the connecting frame 22 and connected by the transmission rod 213.

[0065] A first rack 111 and a second rack 112 are provided on the frame 11. A first gear 212 meshes with the first rack 111, and a second gear meshes with the second rack 112. The motor 211 can drive the first gear 212 and the second gear to rotate, so that the connecting frame 22 moves along the first direction a.

[0066] Due to the connection of the transmission rod 213, the first gear 212 and the second gear can rotate synchronously. The first gear 212 and the second gear at both ends of the connecting frame 22 mesh with the first rack 111 and the second rack 112 on the frame 11, respectively. As the gear set rotates, the teeth of the gears roll along the tooth grooves of the racks. Through the meshing transmission between the gears and the racks, the connecting frame 22 is driven to reciprocate in the first direction a.

[0067] It is understandable that a first rack 111 and a second rack 112 are provided on the frame 11 on both sides of each support frame 12, so that the connecting frame 22 can dock with different support frames 12 to realize the conveying of the material plate.

[0068] On the other hand, this utility model embodiment provides a PCB processing equipment, including a processing machine and a transfer device as described in the above embodiment, which enables the exchange of PCBs between the processing machine and the material bin 1.

[0069] The hopper 1 can transport the material plate to be processed to the processing machine, and the material plate that has been processed on the processing machine is transported to the hopper 1.

[0070] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
