Description

Technical Field

[0001] This utility model relates to the field of circuit board testing equipment, specifically to a submersible auxiliary device for a flying needle machine fixture and a flying needle machine fixture. Background Technology

[0002] When using a flying probe microanalyzer to inspect PCB boards, a clamp is needed to hold the PCB board in place. Traditional clamps often use a clamp-type airbag gripping device, which uses pneumatic drive to open and close the jaws. When the jaws are open, the upper and lower jaws are basically in close proximity on the same vertical plane. Since PCB boards are usually placed vertically downwards, this structure makes it difficult for the PCB board to fall accurately into the jaws, requiring repeated adjustments to its position. It may even damage the PCB board due to collisions with the jaws. Furthermore, the PCB board cannot be lifted up and removed directly when unloading. Utility Model Content

[0003] The purpose of this utility model is to provide a submersible auxiliary device for a flying needle machine clamp and a flying needle machine clamp, which solves the problem of inconvenient loading and unloading of existing clamps.

[0004] The present invention achieves the above objectives through the following technical solution: a submersible auxiliary device for a flying needle machine clamp, the clamp including a frame and two clamping components disposed on the frame, the auxiliary device being disposed at the bottom of the clamping components, the auxiliary device including a support member and a driving member for driving the support member to move.

[0005] The drive member is used to drive the support member to move out from the bottom of the clamping assembly, so as to support the PCB board between the two clamping assemblies before the PCB board is clamped.

[0006] Preferably, the auxiliary device further includes a fixed base located at the bottom of the clamping assembly, and the support member is hinged to the fixed base.

[0007] Preferably, a support block is hinged to the fixed base, and the support member is disposed on the support block.

[0008] Preferably, the fixing seat is stepped, and the fixing seat includes a high step portion and a low step portion, with the support block hinged to the high step portion.

[0009] Preferably, the height of the support member after flipping is higher than the height of the support surface of the clamping assembly, and the top wall of the end of the support member away from the drive member is inclined.

[0010] Preferably, the support member is elongated and extends along the edge of the clamping assembly, and there are two fixing seats and two support blocks, with the support member disposed between the two support blocks.

[0011] Preferably, the driving component is an electric push rod, the bottom of the clamping assembly is provided with a support, and the fixed end and the moving end of the electric push rod are respectively hinged to the support and the supporting component.

[0012] Preferably, the support block and the support member are connected by screws.

[0013] Preferably, a wear-resistant pad is provided between the support block and the fixed seat.

[0014] Preferably, a flying needle machine clamp includes: a frame, two clamping assemblies, and a diving auxiliary device for the flying needle machine clamp as described above.

[0015] The beneficial effects of this utility model are as follows: the driving component drives the support component to move out from the bottom of the clamping device to form an area for supporting the PCB board, which facilitates the vertical dropping of the PCB board. Furthermore, by moving the clamping component, the PCB board on the support component enters the clamping port of the clamping component and is clamped, which improves the convenience of loading the PCB board to the clamping port position and increases the loading efficiency. At the same time, the support component supports the PCB board that moves out of the clamping port of the clamping component, which also facilitates the unloading of the PCB board by the workers.

[0024] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0025] Example 1

[0026] Please see Figure 1 and Figure 2 A submersible auxiliary device for a flying needle machine clamp, the clamp includes a frame 1 and two clamping components 2 (clamp-type clamps), the two clamping components 2 are slidably mounted on the frame 1, the frame 1 is provided with a drive device (the drive device may consist of a motor, a positive and negative threaded screw and two threaded sleeves, the two threaded sleeves are respectively connected to the two clamping components 2, the motor drives the positive and negative threaded screws to rotate, so that the two threaded sleeves move horizontally, so as to move the two clamping components 2), for driving the two clamping components 2 to move towards each other on the frame 1 (towards or away from each other), the auxiliary device is provided at the bottom of the clamping components 2, and the bottom of both clamping components 2 is equipped with an auxiliary device.

[0027] Please see Figure 1 The auxiliary device includes a support member 4 and a driving member 3, with the driving member 3 used to drive the support member 4 to move.

[0028] It should be noted that during loading, the drive unit 3 drives the support member 4 to move out from the bottom of the clamping assembly 2 to form a support area, placing the PCB board above the two support members 4; the clamping assembly 2 opens, and the drive unit drives the two clamping assemblies 2 to move closer together until the edge of the PCB board enters the clamping jaws of the clamping assembly 2, the clamping assembly 2 closes to clamp the PCB board, and at the same time, the drive unit 3 drives the support member 4 to move in the opposite direction and reset, moving the support member 4 below the clamping assembly 2 (hiding the support member 4 so that the clamping device is completely avoided). The test area of ​​the PCB board does not affect probe detection. During material handling, the clamping component 2 opens, and the driving component 3 drives the support component 4 to move out from the bottom of the clamping component 2. Then, the driving device drives the two clamping components 2 to move away from each other, so that the PCB board is removed from the clamping slot of the clamping component 2. At this time, the PCB board is supported by the two support components 4. The PCB board is removed from the support components 4 (the PCB board will not come into contact with the clamping component 2 when it moves up, reducing the interference caused by the close distance between the PCB board and the clamping slot of the clamping component 2, and improving the efficiency of material handling).

[0029] It should also be noted that the support member 4 can be pushed by the drive member 3 to slide horizontally out from the bottom of the clamping assembly 2, or the support member 4 can be pushed by the drive member 3 to rotate out from the bottom of the clamping assembly 2.

[0030] Example 2

[0031] The following is a detailed explanation using a specific embodiment where the support member 4 is pushed and rotated by the driving member 3 to move out from the bottom of the clamping assembly 2:

[0032] Please see Figure 1 and Figure 3 The auxiliary device also includes a fixed base 5 (which can be made of wear-resistant brass) located at the bottom of the clamping assembly 2, and the support member 4 is hinged to the fixed base 5; when the driving member 3 drives the support member 4 to move, the support member 4 rotates and moves out from the bottom of the clamping assembly 2 to support the PCB board. Figure 6 and Figure 7 The diagrams show the two states of support member 4: rotational contraction and extension.

[0033] In this embodiment, as a further optimization, please refer to... Figure 3 , Figure 4 and Figure 5 A support block 7 is hinged to the fixed base 5 (a shaft hole is provided on the side wall of the fixed base 5, and a rotating shaft is provided on the support block 7, with the rotating shaft located in the shaft hole), and the support member 4 is provided on the support block 7; the support block 7 is used to increase the path length of the support member 4 to rotate, ensuring that the support member 4 can be moved out from under the clamping assembly 2.

[0034] In this embodiment, as a further optimization, please refer to... Figure 3 and Figure 4 The fixing seat 5 is stepped, and the fixing seat 5 includes a high step and a low step. The support block 7 is hinged to the high step; it is used to increase the height of the support 4 after it is flipped, so as to ensure that the PCB board supported on the support 4 can enter the clamping mouth of the clamping assembly 2.

[0035] In this embodiment, as a further optimization, please refer to... Figure 7 The height of the support 4 after flipping is higher than the height of the support surface of the clamping component 2 (i.e., the height of the support 4 after flipping is higher than the height of the lower clamping plate of the clamping component 2), ensuring that the PCB board above the support 4 can be normally entered into the clamping mouth of the clamping component 2; the top wall of the end of the support 4 away from the drive component 3 is inclined, so that the flipped and retracted support 4 will not be exposed from the bottom of the clamping component 2.

[0036] In this embodiment, as a further optimization, please refer to... Figure 3 The support member 4 is long and extends along the edge of the clamping assembly 2. There are two fixing bases 5 and two support blocks 7. The support member 4 is located between the two support blocks 7. The length of the support member 4 is increased to increase the area it supports, ensuring that it supports the PCB board stably.

[0037] In this embodiment, as a further optimization, please refer to... Figure 3The driving component 3 is an electric push rod. The bottom of the clamping assembly 2 is provided with a support 6. The fixed end and the moving end of the electric push rod are respectively hinged to the support 6 and the support member 4. Wear-resistant pads are installed in the contact area between the electric push rod and the support 6 and the support member 4.

[0038] In this embodiment, as a further optimization, please refer to... Figure 3 The support block 7 and the support member 4 are connected by screws.

[0039] In this embodiment, as a further optimization, please refer to... Figure 3 A wear-resistant pad 8 is provided between the support block 7 and the fixed seat 5 to provide protection.

[0041] As a further optimization of Example 1, please refer to Figure 1 and Figure 2 A flying needle machine clamp includes: a frame 1, two clamping components 2 and the aforementioned auxiliary devices; the two clamping components 2 are slidably mounted on the frame 1, and the two auxiliary devices are respectively mounted on the bottom of the two clamping components 2.

[0042] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
