Description

Technical Field

[0001] This utility model relates to the field of remote control processing equipment technology, and in particular to a tooling fixture for a foam attaching equipment. Background Technology

[0002] In the field of modern consumer electronics manufacturing, remote controls, as an indispensable human-computer interaction device, face increasingly higher requirements for precision, efficiency, and reliability in their production process. The core internal component of a remote control is the printed circuit board assembly (PCBA). During subsequent PCBA assembly processes, foam is often attached to specific locations. This foam primarily serves crucial functions such as cushioning, shock absorption, insulation, and filling gaps, and is essential for ensuring the stability of the remote control's internal structure, the comfort of the buttons, and its long-term reliability.

[0003] Currently, in the process of attaching foam to remote control PCBAs, operators typically place the PCBA on a fixed, simple support platform, manually align it, cover the predetermined area of ​​the PCBA with foam, and then press to complete the attachment. However, the pressing method relies solely on downward pressure, which makes it difficult to ensure that the foam and the PCBA surface make full and uniform contact. Insufficient pressure can easily lead to poor foam adhesion, causing it to fall off or lift up in subsequent processes or during use.

[0004] Therefore, in order to ensure the adhesion stability of foam to PCBA, we propose a fixture for foam bonding equipment. Summary of the Invention

[0005] The purpose of this utility model is to solve the above-mentioned shortcomings in the existing technology and to propose a tooling fixture for foam bonding equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: Design a fixture for a foam bonding machine, including: Adjustable base and fixture seat mounted on the adjustable base; The front end of the fixture base is rotatably connected to a clamping component and slidably connected to a lifting component. The lifting component and the clamping component are positioned opposite each other to clamp the foam on the PCBA. The fixture base has multiple clearance openings at its upper end, and the clearance openings and the attachment positions of the foam are arranged opposite to each other. At least a portion of the lifting assembly slides in the clearance openings.

[0007] Furthermore, the adjustable base includes: It is equipped with a base plate with two lower upright plates; A lower guide rod is fixedly installed between the two lower upright plates.

[0008] Furthermore, the adjustable base also includes: Two upper plates are fixedly installed on the horizontal adjustment seat, and an upper guide rod is fixedly installed between the two upper plates. A longitudinal adjustment seat is slidably connected to the upper guide rod. A longitudinal adjustment screw that abuts against the longitudinal adjustment seat is threadedly connected to the side of the upper plate.

[0009] Furthermore, an adjusting column is rotatably connected above the longitudinal adjusting seat, and a connecting seat is fixedly installed at the upper end of the adjusting column; Two fixed seats are fixedly installed at the front end of the longitudinal adjustment seat, and an abutment seat located between the two fixed seats is fixedly installed at the front end of the adjustment column. A circumferential adjustment screw that abuts the abutment seat is threadedly connected to the end face of the fixed seat.

[0010] Furthermore, the clamping assembly includes connecting rods pinned to both sides of the fixture base; A flipping frame is pinned between the ends of the two connecting rods, and several clamping blocks are fixedly installed on the end face of the flipping frame.

[0011] Furthermore, a mounting base is fixedly installed on the side of the fixture base, and a push cylinder is fixedly connected to the mounting base. The shaft end of the push cylinder is pin-connected to the side of the tilting frame for rotation.

This allows for rapid and precise positioning based on the actual foam bonding position on the PCBA, greatly improving the fixture's versatility and operational flexibility. Simultaneously, the coordinated clamping and lifting components apply a bidirectional force of downward pressure and upward support to the PCBA, stably clamping and tightly bonding the PCBA and foam.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figure 1-5As an embodiment of this utility model, a jig tooling for a foam bonding equipment is disclosed. Specifically, the jig tooling includes an adjustable base 1 and a jig seat 2 mounted on the adjustable base 1. The adjustable base 1 is mounted on the machine platform and is used to adaptively adjust the horizontal, vertical and circumferential positions of the jig seat 2, so as to ensure that when placing PCBA5, the position of the entire jig seat 2 can be adjusted according to the bonding position. The front end of the fixture base 2 is rotatably connected to a clamping component 3 and slidably connected to a lifting component 4. The lifting component 4 and the clamping component 3 are opposite each other to clamp the foam 6 on the PCBA5. The fixture base 2 has multiple clearance openings 21 at its upper end. The clearance openings 21 and the attachment positions of the foam 6 are arranged opposite to each other. At least a portion of the lifting assembly 4 slides in the clearance openings 21.

[0018] Specifically, the present invention employs a pressing component 3 and a lifting component 4, which can be used to tightly attach the foam 6 to the PCBA5 to ensure the stability of the attachment. The specific operation method will be described in detail later, and will not be elaborated here.

[0019] In some embodiments, the adjustable base 1 of this invention includes: A base plate 12 is configured with two lower upright plates 11, and the two lower upright plates 11 are fixed above the base plate 12 at a horizontal interval; A lower guide rod 13 is fixedly installed between the two lower upright plates 11. A lateral adjustment seat 14 is slidably connected to the lower guide rod 13. A lateral adjustment screw 15 is threadedly connected to the side of the lower upright plate 11, which abuts against the lateral adjustment seat 14.

[0020] In this embodiment, the position of the horizontal adjustment seat 14 is adjusted by adjusting the position of the two horizontal adjustment screws 15 on both sides, thereby changing the horizontal position of the entire jig seat 2. Specifically, in this embodiment, there are two lower guide rods 13. The two ends of the lower guide rods 13 can be connected and fixed to the lower upright plate 11 by fasteners such as bolts to ensure the easy assembly capability of the entire device.

[0021] Based on the above embodiments, the adjustable base 1 in this embodiment further includes: Two upper plates 16 are fixedly installed on the horizontal adjustment seat 14, and an upper guide rod 17 is fixedly installed between the two upper plates 16. A longitudinal adjustment seat 18 is slidably connected to the upper guide rod 17. A longitudinal adjustment screw 19 is threadedly connected to the side of the upper plate 16 to abut against the longitudinal adjustment seat 18.

[0022] Similarly, in this embodiment, the design of two longitudinal adjusting screws 19 can be used to adjust the longitudinal position of the longitudinal adjusting seat 18, thereby achieving adaptive adjustment of the longitudinal position of the jig seat 2. Of course, the upper guide rod 17 mentioned in this embodiment can also be adaptively set to two to ensure the sliding stability of the longitudinal adjusting seat 18.

[0023] Furthermore, in this embodiment, an adjusting column 110 is rotatably connected above the longitudinal adjusting seat 18, and a connecting seat 111 is fixedly installed at the upper end of the adjusting column 110. Two fixed seats 112 are fixedly installed at the front end of the longitudinal adjustment seat 18, and an abutment seat 113 located between the two fixed seats 112 is fixedly installed at the front end of the adjustment column 110. A circumferential adjustment screw 114 that abuts against the abutment seat 113 is threadedly connected to the end face of the fixed seat 112.

[0024] In this embodiment, since the adjusting column 110 and the longitudinal adjusting seat 18 adopt a rotating connection structure design, when adjusting and controlling the circumferential adjusting screws 114 on the two fixed seats 112, the circumferential position of the entire adjusting column 110 can be adjusted by contacting the abutment seat 113. In conjunction with the aforementioned transverse adjusting seat 14 and longitudinal adjusting seat 18, a small range of adjustment of the transverse, longitudinal and circumferential positions of the entire jig seat 2 can be completed to ensure the accuracy of the PCBA5 position positioning.

[0025] Preferably, the clamping assembly 3 in this embodiment includes connecting rods 31 pinned to both sides of the fixture base 2. Of course, there are two connecting rods 31. A flipping frame 32 is pinned between the ends of the two connecting rods 31, and several clamping blocks 33 are fixedly installed on the end face of the flipping frame 32.

[0026] In addition, a mounting base 34 is fixedly installed on the side of the fixture base 2, and a push cylinder 35 is fixedly connected to the mounting base 34. The shaft end of the push cylinder 35 is pin-connected to the side of the flipping frame 32 for rotation.

[0027] In this embodiment, a push cylinder 35 is used to control the entire flipping frame 32 to flip, so that the flipping frame 32 drives the pressing block 33 to abut against the top of the foam 6. In the actual application of foam, the application mechanism first picks up the foam and places it on top of PCBA5. Then, the cylinder 35 is pushed to rotate the flipping frame 32. At this time, the pressing block 33 on the flipping frame 32 presses against the foam 6. Then, the lifting component 4 lifts the entire PCBA5 upward by a small distance to ensure that the foam 6 can be tightly adhered and fixed to the PCBA5.

[0028] Of course, the pressing block 33 described in this embodiment can be set as a rubber block, the number and spacing of which are adapted to the design of the clearance opening 21 described above, so as to ensure the pressing of the foam 6.

[0029] In some embodiments, the lifting assembly 4 of this utility model includes a slide 41 slidably connected to the lower part of the fixture base 2. A plurality of wheel frames 42 are fixedly installed at the front of the slide 41. Rollers 43 are rotatably connected to the ends of the wheel frames 42. The rollers 43 are slidably connected to the clearance opening 21. Specifically, in this embodiment, the wheel frame 42 is set as an L-shaped structure, and the above-mentioned at least part is the upper bent part of the wheel frame 42. Of course, those skilled in the art know that in the initial state, the rollers 43 are housed in the clearance opening 21. In addition, the height of the rollers 43 should protrude from the upper surface of the fixture base 2 by a certain distance. In this way, when the rollers 43 move, they will abut against the lower surface of the PCBA5 and move upward a small distance.

[0030] Of course, in order to control the forward and backward displacement of the slide 41, a displacement cylinder 44 connected to the slide 41 is fixedly installed below the fixture seat 2 in this embodiment. Preferably, the shaft end of the displacement cylinder 44 in this embodiment can be connected to the slide 41 through a floating joint.

[0031] Based on the above embodiments, the jig base 2 in this utility model has a side positioning edge 22 formed on its upper part, and a front positioning plate 23 is also fixedly installed on the upper part of the jig base 2. The end face of the front positioning plate 23 is provided with an inwardly recessed opening 24 that is adapted to the clearance opening 21.

[0032] After the foam 6 is attached, when the clamping block 33 is against the top of the foam 6, the displacement cylinder 44 can be activated. The displacement cylinder 44 drives the slide 41 to move forward. At this time, the upper side of the roller 43 will be against the lower side of the PCBA5. The upward contact force of the roller 43 on the PCBA5 and the downward clamping force of the clamping block 33 can stably combine the foam 6 and the PCBA5 to ensure the attachment stability of the foam 6.

[0033] In addition, the combination of the side positioning edge 22 and the front positioning plate 23 can be used to position the PCBA5 to ensure the accuracy of the mounting operation.

[0034] In summary, the tooling of this utility model, through the design of its adjustable base 1, achieves multi-directional adaptive adjustment of the horizontal, vertical, and circumferential positions of the tooling base 2. This allows for rapid and precise positioning based on the actual attachment position of the foam 6 on the PCBA5, greatly improving the tooling's versatility and operational flexibility. Simultaneously, through the coordinated clamping component 3 and lifting component 4, a bidirectional force of downward clamping and upward support can be applied to the PCBA5, stably clamping and tightly adhering the PCBA5 and the foam 6. This effectively avoids problems such as offset, warping, or air bubbles that are prone to occur during the attachment process, significantly improving the attachment accuracy, bonding strength, and final product quality reliability of the foam.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
