Description

Technical Field

[0001] This utility model relates to the field of PCBA board processing technology, specifically to a PCBA universal suction cup fixture. Background Technology

[0002] As electronic products continue to evolve towards miniaturization and multifunctionality, the types, sizes, and arrangement densities of components on PCBAs (Printed Circuit Board Assemblies) are becoming increasingly diverse. Traditionally, during production testing, transportation, and rework, PCBAs typically require specialized suction cups or clamps to secure the board, ensuring board flatness, preventing component damage, and meeting the positioning accuracy requirements of automated equipment.

[0003] However, the suction cups in the existing technology use fixed hole positions, which require drilling or milling to avoid the components according to the specific PCBA component layout. This results in the need to replace or reprocess when facing different PCBA models or changing component positions, resulting in poor versatility and flexibility.

[0004] Therefore, it is necessary to improve the existing technology to overcome the aforementioned defects. Utility Model Content

Each holding member has a holding portion for holding against a target object, and the plurality of holding portions are located in the same horizontal plane. An adsorption assembly includes a plurality of adsorption elements, which are movably installed in the mounting groove. The adsorption elements are configured to be connected to a negative pressure source to adsorb and fix the target object after the plurality of abutting portions abut against the target object.

[0006] Optionally, in the above-mentioned PCBA universal suction cup fixture, the mounting bracket includes two horizontal supports and two cross supports. The cross supports are used to connect the first and last ends of the two horizontal supports.

[0022] To fully understand this application, detailed steps and structures will be presented in the following description to illustrate the technical solution of this application. Preferred embodiments of this application are described in detail below; however, in addition to these detailed descriptions, this application may have other implementation methods.

[0023] Please refer to Figures 1-6As shown in the preferred embodiment of this application, a universal suction cup fixture for PCBA is used to adsorb target PCBAs for adsorption and transfer. In this embodiment, the universal suction cup fixture for PCBAs (hereinafter referred to as the suction cup fixture) includes a mounting frame 1, a holding assembly 2, and an adsorption assembly 3. The mounting frame 1 has several mounting slots; the holding assembly 2 includes several holding members 21, which are movably installed in the mounting slots. Each holding member 21 has a holding portion for abutting against the target object, and the holding portions are located on the same horizontal plane; the adsorption assembly 3 includes several adsorption members 31, which are movably installed in the mounting slots. The adsorption members 31 are configured to be connected to a negative pressure source 4 to adsorb and fix the target object after the holding portions abut against it.

[0024] Understandably, by setting up several supporting members 21 and several adsorption members 31 that are movably connected in the mounting slot, the positions of the supporting members 21 and adsorption members 31 relative to the target PCBA can be changed arbitrarily. This allows for the sharing of PCBAs with different models or different component layouts, thereby reducing the cost of fixture manufacturing and replacement and improving flexibility and versatility.

[0025] Understandably, both the supporting part 21 and the adsorption part 31 can move flexibly along the mounting groove, which can accurately avoid high-density or high-component boards on the PCBA. At the same time, all supporting parts are kept on the same horizontal plane, so that the overall leveling of the PCBA is completed first, and then the adsorption part 31 adsorbs independently, which ensures that the board surface is flat and the adsorption is reliable.

[0026] In this embodiment, reference Figure 2 As shown, the mounting bracket 1 includes two horizontal supports 11 and two cross supports 12. The cross supports 12 are used to connect the first and last ends of the two horizontal supports 11. The horizontal supports 11 are provided with horizontal mounting grooves 111, and the cross supports 12 are provided with cross mounting grooves 121. A plurality of abutment members 21 and adsorption members 31 are installed in the horizontal mounting grooves 111 and cross mounting grooves 121, and can all be movably connected along the mounting grooves. This layout of the horizontal supports 11 and cross supports 12 can form a two-dimensional array, allowing the abutment members 21 and adsorption members 31 to move in different directions on the same horizontal plane, so as to achieve a uniform distribution of the abutment members 21 and adsorption members 31, ensuring that the abutment members 21 and adsorption members 31 can be almost uniformly distributed on the PCBA with multiple components, thereby ensuring the adsorption stability of the PCBA.

[0027] In this embodiment, each of the supporting members 21 includes a connecting rod 211 connected to the mounting groove and a supporting post 212 connected to the end of the connecting rod 211. The supporting part is located at the bottom of the supporting post 212 so that the position of the supporting post 212 can be adjusted by changing the position of the connecting rod 211.

[0028] Furthermore, the supporting part is tapered so that it makes point contact with the PCBA, reducing the occupied area, making it easier to avoid small pads or test points, and providing an automatic centering effect to improve positioning accuracy.

[0029] Furthermore, the supporting part is made of silicone. The reason for this design is that the silicone supporting part has both elasticity and friction, which can prevent hard contact from damaging the PCBA or components, and absorb slight warping of the board, ensuring that the board surface is completely flat before adsorption.

[0030] In this embodiment, each of the adsorption elements 31 includes a first connecting arm 311 movably connected to the mounting groove, a second connecting arm 312 movably connected to the other end of the first connecting arm 311, and an adsorption pipe 313 installed at the other end of the second connecting arm 312. The first connecting arm 311 can move along the mounting groove, and the second connecting arm 312 can rotate relative to the first connecting arm 311 on a horizontal plane.

[0031] Understandably, by providing a first connecting arm 311 and a second connecting arm 312, the first connecting arm 311 can slide along the mounting groove, while the second connecting arm 312 can rotate relative to the first connecting arm 311. This allows the adsorption pipe 313 to be adjusted to any angle and length in the horizontal plane, precisely positioning it to the optimal adsorption area of ​​the PCBA and avoiding adsorption at cutouts or component locations.

[0032] Furthermore, the second connecting arm 312 has a mounting hole 3121 and a fastener 3122. The mounting hole 3121 is adapted for the adsorption pipe 313 to pass through, and the fastener 3122 is used to fasten or loosen the adsorption pipe 313 and the second connecting arm 312, thereby enabling the adsorption pipe 313 to be quickly adjusted up and down and to be locked instantly according to different plate thicknesses or device heights, thus improving line changing efficiency.

[0033] Furthermore, the adsorption pipe 313 includes a pipe body 3131, a connection port 3132 disposed above the pipe body 3131, and an adsorption port 3133 disposed below the pipe body 3131. The connection port 3132 is connected to the negative pressure source 4, and the adsorption port 3133 is in contact with the target object.

[0034] Specifically, the adsorption port 3133 is a flexible pipe that adapts to local height differences in the PCBA, forming a soft seal to prevent air leakage. It can stably adsorb even if the PCBA has slight warping or solder joint protrusion.

[0035] Further, refer to Figure 6As shown, the adsorption member 31 has an adsorption state for adsorbing the target object and a separation state for separating from the target object; when in the separation state, in the horizontal direction, the lower end of the adsorption member 31 is lower than the lower end of the supporting member 21, so as to ensure that the supporting member 21 completes the positioning and leveling first during the jig descent process, and then the adsorption member 31 contacts the plate surface to perform adsorption; to avoid the adsorption member 31 touching the component in advance and causing interference.

[0036] The above is only one specific implementation of this application, and any other improvements made based on the concept of this application shall be considered within the scope of protection of this application.
