Description

Technical Field

[0001] The utility model relates to the technical field of circuit board processing, and particularly relates to a clamping and picking mechanism. Background Art

[0002] During the operation of a circuit board (PCB board), some components generate a large amount of heat. To ensure the functionality of the circuit board, a heat sink is usually installed on the circuit board to dissipate heat and ensure the stability of the circuit board operation.

[0003] In the assembly operation of the heat sink, the prior art is that an operator places the PCB board on a carrying vehicle and fixes it, and then manually visually places the heat sink in the middle of the heat dissipation glue in the silk screen frame. However, through the visual installation method, it is easy to have the situation that the heat sink and the silk screen frame are not aligned, and the screw holes are not in position, resulting in the locking screws on the heat sink being unable to be installed. Moreover, when the screwdriver is locking, it is easy to damage the heat sink or hit other surrounding components. In mass production, it is impossible to ensure the consistency of the installation position of the heat sink and the operation is inconvenient and the efficiency is not high. When defective components require the heat sink to be removed and replaced, since the heat dissipation glue between the heat sink and the PCB board is cured, it cannot be directly removed. It is necessary to use pliers or special pliers to remove the damaged heat sink, which is easy to scratch the PCB board or hit other surrounding components, resulting in the entire board being scrapped.

[0042] The present utility model provides a clamping and picking mechanism 100. Please refer to Figures 1 to 3 In this embodiment, the clamping and picking mechanism 100 includes a base 1, a clamping arm 2, and a clamping component 3. One end of the clamping arm 2 is rotatably arranged on the base 1. The clamping component 3 is arranged at the other end of the clamping arm 2. The clamping component 3 includes two clamping plates 31 arranged oppositely along the axial direction of the rotation axis of the clamping arm 2, and a driving member 32 arranged to rotate. Wherein, a contact portion is provided on the driving member 32, and a cooperation portion for abutting and cooperating with the contact portion is provided on each of the two clamping plates 31. The driving member 32 rotates relative to the clamping arm 2, driving the contact portion to simultaneously abut against the two cooperation portions, and driving the two clamping plates 31 to move relatively.

[0043] In this embodiment, by rotatably arranging the clamping arm 2 on the base 1, the clamping assembly 3 can be driven to rotate together under the rotation of the clamping arm 2. After the clamping assembly 3 clamps the product (such as a radiator), the radiator can be placed at the specified position on the circuit board through the rotation of the clamping arm 2, making the alignment more accurate and the installation position of the radiator more precise; or, the radiator can be pulled out from the circuit board through the rotation of the clamping arm 2. When removing the radiator, it is not easy to touch the components on the periphery of the radiator, and the circuit board can be better protected from damage; moreover, by adjusting the driving member 32 to act on the two clamping plates 31, the two clamping plates 31 can approach and separate from each other to clamp the product, and the two clamping plates 31 can be adjusted to move manually, with a simpler structure and more convenient control of the clamping force. Through the clamping and picking mechanism 100, the picking and placing operations of the radiator are more convenient, batch precision operations can be carried out, the operation efficiency is higher, and the circuit board can be better protected.

[0044] Among them, the base 1 can be a flat plate, a support, or a bracket formed by overlapping rod structures, etc., which is not specifically limited here, as long as the clamping assembly 3 can better clamp the radiator.

[0045] To make the synchronization of the two clamping plates 31 better, preferably, as shown in Figure 4 and Figure 5 , each clamping plate 31 has a clamping portion 311 and a connecting portion 312. The connecting portions 312 of the two clamping plates 31 are arranged in a stacked manner. Each matching portion includes a matching hole 3121 provided on each connecting portion 312; the driving member 32 passes through the two matching holes 3121, and the abutting portion is correspondingly arranged for the two matching holes 3121. Thus, the abutting portion can simultaneously abut and act on the two matching holes 3121 to drive the two clamping plates 31 to move synchronously, realizing approaching or separating from each other.

[0046] Furthermore, as shown in Figure 4 and Figure 7As shown, the driving member 32 includes a driving shaft 321, and the abutting portion includes an abutting protrusion 322 protruding from the outer peripheral side wall of the driving shaft 321; the driving shaft 321 rotates relative to the two clamping plates 31, so that the abutting protrusion 322 has a first working state of abutting against the two mating holes 3121 and a second working state of being misaligned with the two mating holes 3121. When the driving shaft 321 rotates relative to the clamping arm 2, when the two abutting protrusions 322 rotate to abut against the two mating holes 3121, the two abutting protrusions 322 can simultaneously abut against the hole walls of the two mating holes 3121, thereby pushing the two mating holes 3121 radially outward along the driving shaft 321, so that the two clamping plates 31 can move simultaneously.

[0047] Among them, as Figure 7 shown, the abutting protrusion 322 can be cam-shaped, so as to have a portion with a higher protruding height and a portion with a lower protruding height along the axial direction of the driving shaft 321. The whole abutting protrusion 322 is arranged in a smooth arc shape, so that the driving shaft 321 rotates more smoothly and the acting force can be smaller.

[0048] Flexible members, such as sponge or foam, etc., are provided on both sides of the two clamping portions 311 facing each other. When clamping the radiator, the radiator is contacted through the flexible members, which is not easy to damage the radiator and has a better protection effect on the radiator.

[0049] Moreover, rotating handles are further extended on both sides of the rotating shaft of the clamping arm 2, and a person can hold the rotating handles to drive the clamping arm 2 to rotate.

[0050] Preferably, when in the first working state, the two clamping plates 31 are in a released state of moving away from each other to release the radiator; when in the second working state, the two clamping plates 31 are in a clamping state of approaching each other to clamp the radiator. That is, when the two abutting protrusions 322 simultaneously abut against the two mating holes 3121, the two clamping plates 31 move away from each other, and when the two abutting protrusions 322 are separated from the two mating holes 3121, the two clamping plates 31 approach each other.

[0051] Preferably, as Figure 5As shown, the clamping portion 311 and the connecting portion 312 of the clamping plate 31 are both substantially flat and are perpendicularly arranged. Among them, the clamping assembly 3 further includes a first fixing block 33 and a second fixing block 34. The first fixing block 33 is connected to the clamping arm 2. The second fixing block 34 is connected to the first fixing block 33 and a receiving cavity is formed between the second fixing block 34 and the first fixing block 33. The receiving cavity is provided with openings on both sides along the transverse direction of the rotation axis. The two connecting portions 312 can respectively extend into the receiving cavity from the two openings, and the connecting portions 312 of the two clamping plates 31 are relatively slidably sleeved in the receiving cavity. The driving shaft 321 is rotatably sleeved on the first fixing block 33 and the second fixing block 34 and at least part of it is exposed from the second fixing block 34. By the two connecting portions 312 approaching or separating from each other, the two clamping portions 311 are driven to approach or separate from each other.

[0052] Specifically, a first sliding groove and a second sliding groove provided in the first sliding groove are provided on the first fixing block 33. The second sliding groove is recessed at the bottom of the first sliding groove. The second fixing block 34 covers the opening of the first sliding groove to form a wrapping around the connection between the clamping plate 31 and the driving shaft 321, providing better protection. The two clamping plates 31 are respectively slidably arranged in the first sliding groove and the second sliding groove along the axial direction of the rotation axis. Through the guiding action of the first sliding groove and the second sliding groove, the two clamping plates 31 move more stably.

[0053] Further, in combination with Figure 4 and Figure 6As shown, each of the connecting portions 312 has two first side walls 3122 extending along the axial direction of the rotation axis. The two first side walls 3122 are oppositely arranged along the radial direction of the rotation axis. The first chute has two first guiding walls 331 extending along the axial direction of the rotation axis. The two first guiding walls 331 are oppositely spaced along the radial direction of the rotation axis. The second chute has two second guiding walls 332 extending along the axial direction of the rotation axis. The two second guiding walls 332 are oppositely spaced along the radial direction of the rotation axis. The connecting portion 312 of one of the clamping plates 31 is located between the two first guiding walls 331, and the two first side walls 3122 are in sliding contact with the two first guiding walls 331 one by one. The connecting portion 312 of the other clamping plate 31 is located between the two second guiding walls 332, and the two first side walls 3122 are in sliding contact with the two second guiding walls 332 one by one. Through the two first guiding walls 331 and the two second guiding walls 332, the two first side walls 3122 of the clamping plate 31 are respectively guided to form surface-to-surface contact, which can better ensure that the clamping plate 31 does not shake, so as to clamp the radiator more stably.

[0054] Moreover, in combination with Figure 1 and Figure 3 As shown, the clamping assembly 3 further includes a third fixing block 35. The third fixing block 35 is connected to the second fixing block 34 and is located on the side of the second fixing block 34 facing away from the first fixing block 33. A clamping groove 351 extending along the radial direction of the rotation axis is formed on the third fixing block 35. At least a part of the driving shaft 321 exposed outside the second fixing block 34 is clamped in the clamping groove 351. The driving shaft 321 can be limited and guided through the clamping groove 351, so that the driving shaft 321 is more stable during rotation and is easier to adjust.

[0055] In an embodiment, in combination with Figures 1 to 4 As shown, the clamping and picking mechanism 100 further includes a mounting seat 4 slidably disposed on the base 1 and a seat driving structure 5 connected to the mounting seat 4. The clamping arm 2 is rotatably disposed on the mounting seat 4. By driving the mounting seat 4 to move through the seat driving structure 5, the clamping arm 2 and the clamping assembly 3 can be driven to move together, so as to better adjust the relative position between the clamping assembly 3 and the radiator, and can be better aligned during the picking and placing of different radiators, with a wider application range.

[0056] Preferably, the mounting base 4 has a moving stroke along the transverse direction of the base 1. The seat body driving structure 5 includes a mounting block 51 provided on the base 1 and a screw rod 52 with one end screwed onto the mounting block 51. The screw rod 52 extends along the transverse direction of the base 1 and the other end is screwed onto the mounting base 4. By adjusting the rotation of the screw rod 52, the movement of the mounting base 4 along the transverse direction of the base 1 can be adjusted. The structure is simple and the adjustment is convenient. The movement of the entire clamping and picking mechanism 100 can be manually driven by an operator without the need to set a driving motor. Therefore, the manufacturing cost is lower.

[0057] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structures made by using the description and drawings of the present invention, or directly or indirectly applied to other related technical fields, are equally included in the patent protection scope of the present invention.
