Detailed implementation manners

[0033] In order to further understand the invention content, features and effects of the present utility model, the following embodiments are hereby exemplified and described in detail in conjunction with the accompanying drawings as follows.

[0034] The structure of the present utility model will be described in detail below in conjunction with the accompanying drawings.

[0035] As Figures 1 to 4 shown, a PCB adsorption and grasping device provided by an embodiment of the present utility model includes:

[0036] Fixing plate 1;

[0037] Vacuum suction cup 2: The vacuum suction cup 2 is arranged on the outer surface of the fixing plate 1;

[0038] PCB board 3: The upper surface of the PCB board 3 is in contact with the lower surface of the vacuum suction cup 2;

[0039] Fixing component 4: The fixing component 4 is arranged on the upper surface of the fixing plate 1, and the fixing component 4 includes:

[0040] Fixing shell 401: The lower surface of the fixing shell 401 is fixedly connected to the upper surface of the fixing plate 1;

[0041] "L"-shaped fixing block 402: There are two "L"-shaped fixing blocks 402, and both of the two "L"-shaped fixing blocks 402 penetrate through the inner surface of the fixing shell 401;

[0042] Fixing groove 403: There are two fixing grooves 403, and both of the two fixing grooves 403 are opened on the outer surface of the vacuum suction cup 2, and the inner wall of the fixing groove 403 is in contact with the outer surface of the "L"-shaped fixing block 402.

[0043] Referring to Figure 3 shown, a rebound component 5 is arranged on the surface of the "L"-shaped fixing block 402. There are two rebound components 5, and the two rebound components 5 include:

[0044] Sliding rod 501: Both the left and right ends of the sliding rod 501 are fixedly connected to the inner wall of the fixing shell 401, and the sliding rod 501 penetrates through the surface of the "L"-shaped fixing block 402;

[0045] Telescopic spring 502: The telescopic spring 502 is sleeved on the outer surface of the sliding rod 501. One side of the telescopic spring 502 is fixedly connected to the outer surface of the "L"-shaped fixing block 402, and the opposite side of the telescopic spring 502 is fixedly connected to the inner wall of the fixing shell 401.

[0046] Adopt the above solution: First, the "L"-shaped fixing block 402 moves along the sliding rod 501 towards the opposite side. When the "L"-shaped fixing block 402 moves, it squeezes the telescopic spring 502, causing the telescopic spring 502 to generate elastic force. Place the vacuum suction cup 2 between the fixing plates 1. Then, release the elastic force of the telescopic spring 502 to push the "L"-shaped fixing block 402 towards the relative side until the "L"-shaped fixing block 402 enters the inside of the fixing groove 403, realizing the function of fixing the vacuum suction cup 2.

[0047] Reference Figure 4 As shown, two travel components 6 are provided on the front end face of the "L"-shaped fixing block 402. The two travel components 6 include:

[0048] Travel post 601: The rear end face of the travel post 601 is fixedly connected to the front end face of the "L"-shaped fixing block 402;

[0049] Travel groove 602: The inner wall of the travel groove 602 is in sliding connection with the outer surface of the travel post 601.

[0050] Adopt the above solution: In order to move the "L"-shaped fixing block 402 towards the opposite side, move downward through the travel groove 602. The inner wall of the travel groove 602 squeezes the outer surface of the travel post 601, causing the travel post 601 to be forced to move along the inner wall of the travel groove 602. The travel post 601 can drive the "L"-shaped fixing block 402 to move towards the opposite side.

[0051] Reference Figure 4 As shown, a support plate 7 is provided on the outer surface of the travel groove 602. The inner wall of the support plate 7 is fixedly connected to the outer surface of the travel groove 602, and a transmission component 8 is provided on the upper surface of the support plate 7.

[0052] Adopt the above solution: The support plate 7 mainly plays a role in supporting the travel groove 602.

[0053] Reference Figure 2 As shown, two transmission components 8 are provided. The two transmission components 8 include:

[0054] Tooth plate 801: The lower surface of the tooth plate 801 is fixedly connected to the upper surface of the support plate 7;

[0055] Gear 802: The outer surface of the gear 802 is in a meshing relationship with the outer surface of the tooth plate 801.

[0056] Adopt the above solution: In order to move the support plate 7 downward, rotate the gear 802. The gear 802 meshes with the tooth plate 801, causing the tooth plate 801 to be forced to move downward. The tooth plate 801 then pushes the support plate 7 downward.

[0057] Reference Figure 4As shown in the figure, an auxiliary component 9 is provided on the opposite side of the support plate 7. There are two auxiliary components 9, and the two auxiliary components 9 include:

[0058] Slider 901: One side of the slider 901 is fixedly connected to the opposite side of the support plate 7;

[0059] Support rod 902: Both the upper and lower ends of the support rod 902 are fixedly connected to the inner wall of the fixed shell 401, and the support rod 902 passes through the inside of the slider 901.

[0060] With the above solution: The auxiliary component 9 mainly plays a role in assisting the support plate 7 to move downward.

[0061] Reference Figure 1 As shown in the figure, a driving member 10 is provided on the surface of the gear 802. The driving member 10 passes through the surface of the gear 802 and the front surface of the fixed shell 401, and the rear end surface of the driving member 10 is rotatably connected to the inner wall of the fixed shell 401 through a rotating shaft.

[0062] With the above solution: In order to rotate the gear 802, by rotating the driving member 10, the driving member 10 can drive the gear 802 to rotate together.

[0063] During use, by rotating the driving member 10, the driving member 10 can drive the gear 802 to rotate together. The rotation of the gear 802 meshes with the toothed plate 801, so that the toothed plate 801 is forced to move downward along the outer surface of the support rod 902 through the slider 901. The downward movement of the toothed plate 801 then pushes the support plate 7 to move downward. The support plate 7 drives the travel groove 602 on its surface to move together. The inner wall of the travel groove 602 squeezes the outer surface of the travel column 601, so that the travel column 601 is forced to move along the inner wall of the travel groove 602. The travel column 601 can drive the "L"-shaped fixing block 402 to move in the opposite direction along the sliding rod 501. When the "L"-shaped fixing block 402 moves, it squeezes the telescopic spring 502, causing the telescopic spring 502 to generate elastic force. Then, the old vacuum suction cup 2 is taken out, and the new vacuum suction cup 2 is placed between the fixing plates 1. At this time, the rotation of the driving member 10 is stopped, and the telescopic spring 502 releases the elastic force, pushing the "L"-shaped fixing block 402 to move in the opposite direction until the "L"-shaped fixing block 402 enters the fixing groove 403, completing the installation of the centering vacuum suction cup 2.

[0064] In summary: For this PCB adsorption and grasping device, through the fixing plate 1, the vacuum suction cup 2, the PCB board 3, the fixing component 4, the elastic return component 5, the travel component 6, the support plate 7, the transmission component 8, the auxiliary component 9 and the driving member 10, it solves the problem that when replacing the vacuum suction cup, professional tools are required to disassemble the bolts to take out the vacuum suction cup, and the process is relatively cumbersome. If the bolts fall off and are lost during the disassembly of the bolts, it will cause the new vacuum suction cup to be unable to be installed.
