[0032] Printed circuit board assemblies (PCBAs) are a crucial component of modern electronic devices and are widely used in a wide range of electronic products, including smartphones, tablets, laptops, telecommunications cabinets, and medical equipment. PCBs typically require the use of foam for cushioning, shock absorption, and electrostatic protection. In related technologies, the foam is manually bonded to the PCB. However, the foam is relatively soft and prone to deformation and skew during installation.

[0033] The present application provides a fixture for assembling foam, which can control the position of the foam on the structure to be assembled, and can also correct the foam that is deformed and skewed during the assembly process and reshape the foam. The foam 3 is sleeved on the mounting portion 2 of the structure to be assembled 1.

[0034] Combine Figure 1 and Figure 2 As shown, the clamp provided in this application includes a base 100 , an upper cover plate 200 and a side cover plate 300 .

[0035] The base 100 has an upper surface 101 for supporting the structure 1 to be assembled.

[0036] The upper cover plate 200 is movably disposed on the base 100 . The upper cover plate 200 is used to cooperate with the upper surface 101 to clamp the structure to be assembled 1 . The mounting portion 2 is at least partially exposed to the sides of the base 100 and the upper cover plate 200 .

[0037] The side cover 300 is movably arranged on one side of the base 100. The side cover 300 is provided with a through hole 301 matching the shape of the mounting portion 2. The side cover 300 is used to be sleeved on the mounting portion 2 and cooperate with the base 100 and the upper cover 200 to clamp the foam 3.

[0038] Under the premise of adopting the above technical solution, combined with Figure 3As shown, the structure 1 to be assembled is first placed on the upper surface 101 of the base 100, and then the upper cover 200 is used to clamp the structure 1 to be assembled, thereby fixing and positioning the structure 1. The side cover 300 is provided with a through hole 301 that matches the shape of the mounting portion 2. Therefore, the side cover 300 can be sleeved onto the mounting portion 2 of the structure 1 to be assembled, and the side surfaces of the side cover 300, the base 100, and the upper cover 200 cooperate to clamp the foam 3 in place. This not only controls the position of the foam 3 on the structure 1 to be assembled, but also corrects and reshapes the foam 3 if it becomes deformed or skewed during assembly.

[0039] It is understandable that, combined with Figure 2 and Figure 3 As shown, the foam 3 can be installed on the mounting portion 2 of the structure 1 to be assembled before the structure 1 to be assembled is placed on the upper surface 101, or the foam 3 can be installed on the mounting portion 2 of the structure 1 to be assembled after the structure 1 to be assembled is clamped by the upper cover 200. The foam is located between the side of the upper cover 200 and the side cover 300.

[0040] In some embodiments, combined Figure 2 As shown, the upper surface 101 has a first end side, and the upper cover 200 includes a first pivot side, which is rotatably connected to the first end side. In this arrangement, the upper cover 200 is rotatably mounted on the base 100. By rotating the upper cover 200, the upper cover 200 rotates downward to engage with the upper surface 101 to clamp the structure to be assembled 1. The upper cover 200 is extended upward to release the structure to be assembled 1, making it easy to use.

[0041] In some embodiments, combined Figure 2 As shown, the first pivot side of the upper cover 200 is rotatably connected to the first end side via the first rotating shaft. In this way, it is convenient to realize the rotatable connection between the upper cover 200 and the base.

[0042] For example, a first bearing is provided on the first pivoting side of the upper cover plate 200, and a second bearing is provided on the first end side of the upper surface 101. The first rotating shaft passes through the first bearing and the second bearing in sequence to realize a rotational connection between the first pivoting side of the upper cover plate 200 and the first end side through the first rotating shaft.

[0043] In some embodiments, combined Figure 1 and Figure 2As shown, the upper surface 101 has a second end side opposite the first end side. A limiting post 102 is provided on the second end side of the upper surface 101. The limiting post 102 is used to contact the upper cover plate 200 to define the minimum distance between the upper cover plate 200 and the upper surface 101. When the upper cover plate 200 is fastened, the lower surface of the upper cover plate 200 contacts the limiting post 102, and the upper cover plate 200 is prevented from approaching the upper surface 101 by the limiting post 102. In this way, the limiting post 102 can define the minimum distance between the upper cover plate 200 and the upper surface 101, thereby preventing the upper cover plate 200 from crushing the structure 1 to be assembled.

[0044] Optionally, combined Figure 1 As shown, two limiting posts 102 are provided on the second end side of the upper surface 101, and the two limiting posts 102 are respectively provided at two opposite ends of the second end side. This can further enhance the stability and safety of the support of the upper cover plate 200 and protect the structure 1 to be assembled from damage.

[0045] In some embodiments, combined Figure 1 As shown, the upper cover 200 also includes a first side panel 201, and the base 100 is provided with a second side panel 103 corresponding to the first side panel 201. The first side panel 201 and the second side panel 103 are respectively provided with a first avoidance notch 202 and a second avoidance notch 104 matching the shape of the mounting portion 2, and the first side panel 201 and the second side panel 103 are used to support the foam 3.

[0046] The first side panel 201 and the second side panel 103 are contoured according to the features of the foam and the mounting portion 2. When the upper cover 200 is buckled, the first side panel 201 and the second side panel 103 are clamped on the mounting portion 2. The mounting portion 2 passes through the first avoidance notch 202 and the second avoidance notch 104 and is exposed on one side of the base 100. The foam 3 is sleeved on the exposed portion of the mounting portion 2. The foam is located between the first side panel 201, the second side panel 103 and the side cover 300. The first side panel 201 and the second side panel 103 can resist the foam 3 and limit the foam 3 to prevent the foam 3 from continuing to move inward. The side cover 300 squeezes the foam 3, shapes the foam 3, and ensures that the foam 3 is installed to the expected position of the mounting portion 2.

[0047] In some embodiments, combined Figure 1 As shown, the side cover 300 includes a second pivoting side, which is rotatably disposed on the first side surface of the base 100. With this arrangement, the side cover 300 is rotatably disposed on the base 100. By rotating the side cover 300, the side cover 300 is snapped upward and can be sleeved onto the mounting portion 2. The side cover 300 is located on the side of the foam away from the first side panel 201. In this way, the side cover 300 can cooperate with the first side panel 201 and the second side panel 103 to clamp the foam 3, thereby reshaping the foam 3 that has been skewed or deformed during assembly.

[0048] In some embodiments, combined Figure 1 As shown, the side cover 300 also includes a free side opposite the second pivoting side. This free side is provided with a limit block 302, which protrudes toward the side closest to the upper cover 200. The limit block 302 is configured to contact the upper cover 200 to define the minimum distance between the upper cover 200 and the side cover 300. When the side cover 300 is engaged, the first side panel 201 contacts the limit block 302, preventing the side cover 300 from moving any closer to the first side panel 201. This limit block 302 defines the minimum distance between the first side panel 201 and the side cover 300, thereby pressing the foam 3 into place and preventing excessive compression of the foam 3.

[0049] Optionally, combined Figure 1 As shown, the free side of the side cover 300 is provided with a plurality of limit blocks 302, which are evenly distributed along the free side of the side cover 300. This can improve the stability and safety of the position limitation of the first side plate 201 and the side cover 300, and protect the foam 3 from damage.

[0050] In some embodiments, the limiting block further protrudes toward a side away from the upper cover plate 200. In this arrangement, the operator can hold the protruding portion of the limiting block with his hand to rotate the side cover plate 300, which is convenient for operation.

[0051] In some embodiments, the second pivoting side is rotatably connected to the first side surface via a second rotating shaft, thereby facilitating the rotatable connection between the side cover 300 and the base 100 .

[0052] For example, the second pivoting side of the side cover 300 is provided with a third bearing, the base 100 is provided with a fourth bearing, and the second rotating shaft passes through the third bearing and the fourth bearing in sequence to achieve a rotatable connection between the side cover 300 and the base 100.

[0053] In some embodiments, the structure to be assembled 1 is provided with a plurality of matching structures, and the upper surface 101 is provided with a plurality of positioning structures 105 , and the positioning structures 105 correspond to the matching structures one by one.

[0054] When the structure to be assembled 1 is mounted on the upper surface 101 of the base 100, the mating structure is connected to the positioning structure 105 in a one-to-one correspondence. This reduces assembly errors of the structure to be assembled 1 and improves the accuracy of the positioning and shaping of the fixture's foam. Furthermore, the connection between the positioning and mating structures securely secures the structure to be assembled 1 on the upper surface of the base 100, preventing displacement of the structure 1 during use of the fixture, further improving the accuracy of the positioning and shaping of the foam. Furthermore, the positioning and mating structures provide a certain degree of foolproofing, allowing operators to simply and directly install the structure to be assembled on the base 100, making the operation easier and reducing the skill requirements.

[0055] Optionally, combined Figure 1 As shown, the positioning structure 105 is a protrusion, and the matching structure is a groove. When the structure to be assembled 1 is installed on the upper surface 101 of the base 100, the protrusions are inserted into the grooves in a one-to-one correspondence.

[0056] Optionally, the positioning structure 105 may be a cylinder, a cuboid or a truncated cone, and correspondingly, the groove may be a cylindrical groove, a cuboid groove or a truncated cone groove, which may be flexibly set according to requirements.

[0057] Optionally, the positioning structure 105 is asymmetrically arranged on the upper surface 101 of the base. Such an arrangement is conducive to preventing mistakes and avoiding installation errors of the structure 1 to be assembled.

[0058] One of the processes for assembling foam with the fixture provided in this application is as follows:

[0059] Step 1, combine Figure 3 As shown, the structure 1 to be assembled is assembled to the upper surface 101 of the base 100 .

[0060] Step 2, combine Figure 5 As shown, the upper cover plate 200 is buckled downwards, so that the upper cover plate 200 and the base 100 clamp the structure to be assembled 1 and expose the mounting portion 2 of the structure to be assembled 1.

[0061] Step 3: Install the foam 3 to the installation portion 2 of the structure to be assembled 1.

[0062] For example, the foam 3 may be installed to the installation portion 2 of the structure to be assembled 1 manually or by a robot.

[0063] Step 4, combine Figure 6 As shown, the side cover 300 is rotated and buckled, and the side cover 300, the base 100 and the upper cover 200 cooperate to clamp the foam 3 in place and shape the foam 3.

[0064] Step 5: Open the side cover 300 and the upper cover 200 in sequence and take out the structure 1 to be assembled with the foam 3 .

[0065] Another process of assembling foam with a fixture provided by this application is as follows:

[0066] Step 1, combine Figure 3 As shown, the structure 1 to be assembled is assembled to the upper surface 101 of the base 100 .

[0067] Step 2, combine Figure 4 As shown, the foam 3 is installed on the installation portion 2 of the structure to be assembled 1. For example, the foam 3 can be installed on the installation portion 2 of the structure to be assembled 1 manually or by a robot.

[0068] Step 3, combine Figure 5 As shown, the upper cover plate 200 is buckled downwards, so that the upper cover plate 200 and the base 100 clamp the structure to be assembled 1 and expose the mounting portion 2 of the structure to be assembled 1.

[0069] Step 4, combine Figure 6 As shown, the side cover 300 is rotated and buckled, and the side cover 300, the base 100 and the upper cover 200 cooperate to clamp the foam 3 in place and shape the foam 3.

[0070] Step 5: Open the side cover 300 and the upper cover 200 in sequence and take out the structure 1 to be assembled with the foam 3 .
