Description

Technical Field

[0001] This utility model relates to the technical field of circuit board installation tools, specifically an automatic circuit board installation device. Background Technology

[0002] In conventional technology, plastic parts are usually installed on circuit boards using screws, which is inefficient and costly. Therefore, we considered using inverted plastic parts to install circuit boards. The existing installation method involves manually prying open the inverted structure and then manually inserting the circuit board for installation. Although this eliminates the need for screws, manual installation is inefficient and suffers from inconsistent prying open of the inverted structure and poor positioning accuracy when inserting the circuit board, which is not conducive to large-scale mass production.

[0003] Therefore, this application proposes an automatic circuit board mounting device that facilitates automatic circuit board mounting and has a compact structure. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and propose an automatic circuit board installation device that is conducive to realizing automatic circuit board installation and has a compact structure.

[0005] Compared with the prior art, this utility model proposes an automatic circuit board mounting device, including a frame and a control unit. Three structures are installed along the top, middle and bottom of the frame: an adsorption structure, a spreading structure and a support structure. The adsorption structure and the support structure can reciprocate in the vertical direction. The support structure is used to install inverted plastic parts. The spreading structure has a first support leg and a second support leg that can reciprocate laterally. The first support leg and the second support leg are located on the upper side of the support structure, and there is a gap between the first support leg and the second support leg. The suction port of the adsorption structure can deliver the circuit board to the inverted plastic parts on the support structure through the gap.

[0006] The control unit controls the upward movement of the support structure to connect the first and second support legs with the first and second clips of the clip-on plastic parts. Then, it controls the first and second support legs to move laterally in opposite directions to open the first and second clips and form an installation space. Next, it controls the suction structure to move downward to place the circuit board into the installation space. After the circuit board is placed or installed, it moves upward and retracts. After the circuit board is placed, the control unit controls the first and second support legs to move laterally towards each other to reset and close the first and second clips. The first and second clips press and fix the circuit board. Then, it controls the support structure to move downward to separate the first and second support legs from the first and second clips of the clip-on plastic parts, so that the clip-on plastic parts with the circuit board installed can be removed from the support structure.

[0007] Compared with the prior art, the present invention has the following advantages after adopting the above structure:

[0008] This disclosure, through improvements, facilitates the automatic installation of circuit boards. Furthermore, the adsorption structure, the spreading structure, and the support structure are installed along the upper, middle, and lower parts of the frame, and the structural arrangement of the adsorption structure, the spreading structure, and the support structure results in a compact structure. In summary, this disclosure facilitates the automatic installation of circuit boards and has a compact structure.

Detailed Implementation

[0028] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The embodiments described below are merely examples, and other obvious variations will arise for those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0029] Those skilled in the art should understand that, in the disclosure of this utility model, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0030] like Figures 1 to 9 As shown, this disclosure proposes an automatic circuit board mounting device, including a frame and a control unit. Three structures are installed along the top, middle and bottom of the frame, namely an adsorption structure 30, a spreading structure 31 and a support structure 32. The adsorption structure 30 and the support structure 32 can reciprocate in the vertical direction. The support structure 32 is used to install the inverted plastic part 1. The spreading structure 31 has a first support leg 2 and a second support leg 3 that can reciprocate laterally. The first support leg 2 and the second support leg 3 are located on the upper side of the support structure 32, and there is a gap between the first support leg 2 and the second support leg 3. The suction port 4 of the adsorption structure 30 can deliver the circuit board 5 to the inverted plastic part 1 on the support structure 32 through the gap.

[0031] The control unit controls the support structure 32 to move upward so that the first support leg 2 and the second support leg 3 connect with the first buckle 6 and the second buckle 7 of the buckle plastic part 1. Then, it controls the first support leg 2 and the second support leg 3 to move laterally in opposite directions to open the first buckle 6 and the second buckle 7 to form an installation space. Next, it controls the adsorption structure 30 to move downward so as to place the circuit board 5 into the installation space. After the circuit board 5 is placed or installed, it moves upward and retracts. After the circuit board 5 is placed, the control unit controls the first support leg 2 and the second support leg 3 to move laterally towards each other to reset and close the first buckle 6 and the second buckle 7. The first buckle 6 and the second buckle 7 press and fix the circuit board 5. Then, it controls the support structure 32 to move downward so that the first support leg 2 and the second support leg 3 separate from the first buckle 6 and the second buckle 7 of the buckle plastic part 1, so that the buckle plastic part 1 with the circuit board 5 installed can be removed from the support structure 32.

[0032] As can be seen from the above, the adsorption structure 30 can move upward and retract after the circuit board 5 has been placed or installed. In this example, it moves upward and retracts after the circuit board 5 has been installed, because the adsorption structure 30 can maintain its positioning effect on the circuit board 5. The time when the circuit board 5 is installed is at least after the first inverted clip 6 and the second inverted clip 7 have pressed and fixed the circuit board 5.

[0033] Because of its compact structure, this disclosure allows for the setup of multiple workstations, such as... Figure 1 As shown, two workstation units are arranged side by side on the support platform 33, and each workstation unit has the same structure.

[0034] like Figure 2 , 3 As shown, for a workstation unit, its frame includes an upper L-shaped frame 8 and a lower L-shaped frame 9. The first horizontal portion 10 of the upper L-shaped frame 8 and the second horizontal portion 11 of the lower L-shaped frame 9 are arranged parallel to each other. The spreading structure 31 is clamped and fixed between the first horizontal portion 10 and the second horizontal portion 11. The first vertical portion 12 of the upper L-shaped frame 8 is equipped with an adsorption structure 30, and the second vertical portion 13 of the lower L-shaped frame 9 is equipped with a support structure 32. In this way, the structure is reliably supported and more compact.

[0035] In some embodiments, such as Figure 1 , 2 As shown in Figure 9, the adsorption structure 30 includes a suction head 14 with a suction port 4 at its lower end. It also includes a movable bracket connected to the first vertical portion 12. The movable bracket is detachably connected to the suction head 14, allowing the suction head 14 to be removed for replacement and / or cleaning. This facilitates maintenance of the suction head 14 and allows for the replacement of different suction heads 14 to adapt to different circuit boards 5, resulting in better adsorption performance.

[0036] The suction head 14 is connected to the air pump via a pipe.

[0037] Furthermore, such as Figure 1 , 2 As shown in Figure 9, the movable support includes a first linear moving part 15, the lower end of which is detachably mounted with a suction head 14. The first linear moving part 15 is used to drive the suction head 14 to reciprocate vertically. This facilitates the reliable and accurate delivery of the circuit board 5 to the installation space during mass production, i.e., during repetitive processes.

[0038] In this example, the first linear moving part 15 adopts a first cylinder, which includes a first telescopic rod 34 and a first connecting plate 35. The lower end of the first telescopic rod 34 is connected to the first connecting plate 35, and the front end of the first connecting plate 35 is detachably connected to the suction head 14.

[0039] In the initial position, the suction head 14 is located on the upper side of the interval. At this time, the circuit board 5 can be sent to the lower side of the suction port 4 by a robot or worker, so that the suction port 4 can hold the circuit board 5. Then, when the worker presses the start button, the first telescopic rod 34 can drive the circuit board 5 to be accurately placed into the installation space according to the assembly sequence. After the circuit board 5 is placed or installed, it moves upward and returns to the initial position.

[0040] In some embodiments, such as Figure 1 , 2 As shown in Figure 9, the support structure 32 includes a mounting portion 16 and a second linear moving portion 17 arranged vertically. The second linear moving portion 17 is connected to the second vertical portion 13, and its upper end is connected to the mounting portion 16. The second linear moving portion 17 drives the mounting portion 16 to reciprocate vertically relative to the supporting portion. In this way, the supporting portion does not need to reciprocate vertically, which helps to simplify the structure.

[0041] In this example, the second linear moving part 17 adopts a second cylinder, which includes a second telescopic rod 36 and a second connecting plate 37. The upper end of the second connecting plate 37 is connected to the mounting part 16, and the second telescopic rod 36 drives the mounting part 16 to move vertically up and down reciprocally.

[0042] Furthermore, such as Figure 7 , 8 As shown, a mounting limiting hole 18 is provided on the upper side of the mounting part 16. The mounting limiting hole 18 is used for the detachable mounting of the undercut plastic part 1. The peripheral wall 19 of the mounting limiting hole 18 is used to circumferentially cooperate with the lower protrusion of the undercut plastic part 1 to position the undercut plastic part 1. In this way, when the undercut plastic part 1 is placed into the mounting limiting hole 18, it can be positioned well, providing a reference for the subsequent assembly of the circuit board 5, which is conducive to the completion of the assembly.

[0043] Furthermore, such as Figure 7As shown, the bottom surface 20 of the mounting limiting hole 18 is set lower than the lower side surface of the circuit board 5 into which it is placed. This facilitates proper placement of the circuit board 5 when it is inserted into the mounting limiting hole 18, and also helps to avoid damage to the components on the lower side surface of the circuit board 5.

[0044] In some embodiments, such as Figure 1 , 2 As shown in Figure 6, both the first support leg 2 and the second support leg 3 of the spreading structure 31 include a support arm 21 and a spreading arm 22. The two support arms 21 are arranged side by side with a gap, and both spreading arms 22 are suspended. The two suspended ends 25 extend relative to the first inverted inclined surface 23 and the second inverted inclined surface 24, respectively. Both suspended ends 25 are provided with spreading fingers 26. The spreading fingers 26 corresponding to the first inverted inclined surface 23 are used to abut against the first inverted inclined surface 23 and spread the first invert 6. The spreading fingers 26 corresponding to the second inverted inclined surface 24 are used to abut against the second inverted inclined surface 24 and spread the second invert 7. In this way, the first support leg 2 and the second support leg 3 are connected / separated from the first invert 6 and the second invert 7 of the inverted plastic part 1 through abutment. The structure is extremely simple.

[0045] Furthermore, such as Figure 1 , 2 As shown in Figure 3, the spreading structure 31 also includes a thumb cylinder 27, which includes two relatively linearly opening and closing fingers, namely a first finger 28 and a second finger 29. The first finger 28 is connected to the first support leg 2, and the second finger 29 is connected to the second support leg 3. Thus, the thumb cylinder 27 is a prior art component, which is further connected to the first support leg 2 and the second support leg 3 to obtain the spreading structure 31, which is convenient to implement and has low cost.

[0046] Furthermore, such as Figure 1 , 2 As shown in Figure 3, the spreading structure 31 being clamped and fixed between the first transverse portion 10 and the second transverse portion 11 means that the thumb cylinder 27 is clamped and fixed between the first transverse portion 10 and the second transverse portion 11, while the first finger 28 and the second finger 29 extend forward. This design facilitates a simpler and more compact structure.

[0047] The control unit, such as a conventional PLC (Programmable Logic Controller) control unit, automatically assembles the first cylinder, the second cylinder, and the thumb cylinder 27 according to the assembly sequence. Since the control of the cylinders is a conventional technical means, it will not be described in detail here.

[0048] In this disclosure, workers can first place the inverted plastic parts 1 and circuit boards 5, and then press the start button. The control unit controls the first cylinder, the second cylinder, and the thumb cylinder 27 to operate according to the assembly sequence. One inverted plastic part 1 is installed within one control cycle. After installation, the worker can take out the inverted plastic part 1 with the circuit board 5 installed, and then put in the next set of inverted plastic parts 1 and circuit boards 5, and so on, to achieve continuous production.

[0049] Of course, further automation can be achieved by automatically inserting the inverted plastic part 1 and the circuit board 5, but the structure will become more complex and requires further research.

[0050] When understanding this disclosure, the above structure may be referred to other embodiments / appendices if necessary. Figure 1 And that's understood, so I won't go into details here.

[0051] The above description is merely an illustrative embodiment of this utility model. Therefore, all equivalent changes or modifications made to the structure, features, and principles described in the scope of protection of this utility model are included within the scope of protection of this utility model.
