Description

Technical Field

[0001] The utility model relates to the field of printed circuit board production and manufacturing, and particularly relates to an insertion auxiliary jig. Background Art

[0002] A printed circuit board is a carrier for electronic components. During the assembly production process of the printed circuit board, electronic components need to be inserted into the circuit board one by one. There is a type of electronic component inserted into a to-be-inserted position on the side of the circuit board. The electronic component has a slot that is inserted and matched with the side of the circuit board, and there are multiple metal feet arranged at intervals on one side wall of the slot. This electronic component is generally manually inserted into the to-be-inserted position on one side of the circuit board. After insertion, the contact points between the metal feet and the surface of the circuit board are in contact, thereby electrically connecting the electronic component to the circuit board.

[0003] In order to ensure good contact between the electronic component and the circuit board, it is necessary to ensure that the contact points between the metal feet and the surface of the circuit board are in close contact. Therefore, the width of the slot of this electronic component is designed to be relatively narrow, only slightly larger than the thickness of the circuit board, to reduce the gap between the contact points of the metal feet and the surface of the circuit board. This makes it difficult to quickly align the slot of the electronic component with the to-be-inserted position on one side of the circuit board purely by hand during the insertion process, resulting in a low installation efficiency of the circuit board. Moreover, if the slot of the electronic component is not aligned with the to-be-inserted position on one side of the circuit board, it may also cause the circuit board to hit the metal feet on the slot wall during the insertion process, resulting in problems such as deformation and loosening of the metal feet, affecting the installation quality of the circuit board.

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0032] The present invention provides an insertion auxiliary jig for assisting a worker to manually insert an electronic component 6 into a to-be-inserted position on the side of a circuit board 5 and solve the problem of how to improve the installation efficiency and quality of the circuit board 5. The electronic component 6 has a slot 61 that is inserted and matched with the side of the circuit board 5, and a plurality of metal pins 62 arranged at intervals are provided on one side wall of the slot 61. The metal pins 62 are used to contact the contact points on the surface of the circuit board 5, so as to electrically connect the electronic component 6 to the circuit board 5.

[0033] Refer to Figure 1 and Figure 3 as shown, Figure 1 is a perspective view of the insertion auxiliary jig in the embodiment, Figure 3 is a perspective view of the usage state of the insertion auxiliary jig in the embodiment. The insertion auxiliary jig includes a base 1, a flat plate 2, and a pushing assembly 3.

[0034] The flat plate 2 is located on the base 1, and the flat plate 2 has a circuit board slot 21 and a plug-in slot 22. The circuit board slot 21 is used to accommodate and position the circuit board 5. The plug-in slot 22 is located on one side of the circuit board slot 21 and is communicated with the circuit board slot 21. The plug-in slot 22 is used to accommodate the to-be-inserted electronic component 6 and make the electronic component 6 opposite to the to-be-inserted position on one side of the circuit board 5.

[0035] The pushing assembly 3 includes a push block 32 and a driving member 31. The driving member 31 is installed on the base 1 and is connected to the push block 32. The driving member 31 is used to push the push block 32 to slide towards the plug-in slot 22 to push the electronic component 6 in the plug-in slot 22 onto the to-be-inserted position of the circuit board 5.

[0036] When the plug-in auxiliary jig provided by the above technical solution is used, first, the circuit board 5 is placed in the circuit board slot 21, and the position of the circuit board 5 is fixed through the circuit board slot 21. Then, the electronic component 6 to be plugged is placed in the plug-in slot 22, so that the electronic component 6 is opposite to the plug-in position on one side of the circuit board 5. Finally, the driving member 31 is used to push the push block 32 to slide towards the plug-in slot 22, and the electronic component 6 in the plug-in slot 22 is plugged onto the plug-in position on one side of the circuit board 5. It can be seen that for this plug-in auxiliary jig, only by placing the circuit board 5 and the electronic component 6 to be plugged into the corresponding slots respectively, can it assist the staff to quickly align the plug slot 61 of the electronic component 6 with the plug-in position on one side of the circuit board 5, ensuring that the electronic component 6 can be accurately plugged onto the plug-in position on one side of the circuit board 5 under the thrust of the pushing component 3, effectively improving the installation efficiency of the circuit board 5, and effectively avoiding the situation that the circuit board 5 hits the metal pin 62 of the electronic component 6 due to the misalignment with the electronic component 6, thereby ensuring the installation quality of the circuit board 5; and the circuit board slot 21 on the flat plate 2 can not only fix the position of the circuit board 5, avoiding the displacement of the circuit board 5 during the plugging process, but also helps to keep the circuit board 5 flat, greatly reducing the possibility of the circuit board 5 being bent and deformed under force during the plugging process, further effectively avoiding the circuit board 5 hitting the metal pin 62 of the electronic component 6 during the plugging process, thereby further improving the installation quality of the circuit board 5.

[0037] The above circuit board slot 21 is adapted to the circuit board 5 to be produced, and the above plug-in slot 22 is adapted to the electronic component 6 to be plugged.

[0038] Refer to Figure 2 and Figure 3 as shown, Figure 2 Fig. is a perspective view of the plug-in auxiliary jig in the open state of the pressing plate 4 in the embodiment. The plug-in auxiliary jig further includes a pressing plate 4. The pressing plate 4 is rotatably connected to the base 1 by means of hinge or rotating shaft, etc., and is used to cover the flat plate 2. The pressing plate 4 has a relief recess 41, and the relief recess 41 is used to expose the plug-in position of the circuit board 5. The depth of the circuit board slot 21 is less than or equal to the thickness of the circuit board 5. It can be seen that the pressing plate 4 has an open state and a closed state. Since the depth of the circuit board slot 21 is less than or equal to the thickness of the circuit board 5, when the pressing plate 4 is in the closed state, it can directly press on the circuit board 5 and cooperate with the flat plate 2 to flatten the circuit board 5, further keeping the circuit board 5 flat, thereby further avoiding the displacement or bending and deformation of the circuit board 5 under force during the plugging process. Among them, the relief recess 41 can expose the plug-in position of the circuit board 5, effectively avoiding the interference between the electronic component 6 and the pressing plate 4 during the plugging process. When the pressing plate 4 is in the open state, it can expose the circuit board slot 21, facilitating the removal or insertion of the circuit board 5.

[0039] Refer to Figure 1 、 Figure 2 and Figure 4As shown Figure 4 FIG. Figure 4 is an exploded view of the plugging auxiliary jig in the embodiment. In one embodiment of the driving member 31, the driving member 31 includes a crank 311, a first connecting rod 312 and a second connecting rod 315. The crank 311 is rotatably connected to the base 1 through a pin shaft. Two ends of the first connecting rod 312 are respectively rotatably connected to the crank 311 and one end of the second connecting rod 315 through pin shafts. The second connecting rod 315 and the pushing block 32 are both slidably connected to the base 1 toward the plugging slot 22 through a hole groove or a slide rail or the like. The other end of the second connecting rod 315 is connected to the pushing block 32 by welding or screwing or the like. The crank 311 drives the second connecting rod 315 to slide through the first connecting rod 312. Thus, when using this plugging auxiliary jig, only by swinging the crank 311, the second connecting rod 315 can be driven to slide, so as to drive the pushing block 32 to push the electronic component 6 to be plugged at the to-be-plugged position of the circuit board 5. This driving method is simple and easy to operate.

[0040] Refer to Figure 1 and Figure 2 As shown in FIGS. Figure 1 and Figure 2 , in one embodiment of the crank 311, the crank 311 includes a connecting end 313 and a stress end 314. The connecting end 313 and the stress end 314 are respectively located on both sides of the transition joint of the crank 311. The connecting end 313 extends downward and is rotatably connected to one end of the first connecting rod 312 through a pin shaft. The stress end 314 extends upward. The stress end 314 is used to drive the connecting end 313 to swing in a direction close to or away from the pushing block 32. Thus, with the connecting end 313 facing downward, the second connecting rod 315 can be driven to slide left and right through the first connecting rod 312, reducing the transmission dead point, and the upward extension of the stress end 314 can facilitate the staff to push the crank 311 to swing.

[0041] A handle can be arranged on the above-mentioned stress end 314 to facilitate the staff to push the crank 311 to swing.

[0042] Refer to Figure 1 and Figure 4 As shown in FIGS. Figure 1 and Figure 4 , in one embodiment of the flat plate 2, positioning posts 24 are arranged at the bottom of the circuit board slot 21 through integral connection or bonding or the like. The positioning posts 24 are used for clearance fit with the through holes 51 of the circuit board 5 and positioning the circuit board 5. Thus, when the circuit board 5 is placed into the circuit board slot 21, the positioning posts 24 in the circuit board slot 21 can be synchronously inserted into the through holes 51 of the circuit board 5, and position the circuit board 5 together with the circuit board slot 21, further ensuring that the circuit board 5 will not shift during the plugging process.

[0043] Refer to Figure 1 and Figure 4As shown, in one embodiment of the base 1, a number of limiting posts 11 are provided on the base 1 by means of welding or integral connection. A limiting space 13 is formed between the number of limiting posts 11. The limiting space 13 is used to accommodate and limit the position of the flat plate 2. In this way, it effectively prevents the flat plate 2 from moving during the insertion process, thereby avoiding the flat plate 2 driving the circuit board 5 to shift during the insertion process.

[0044] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in one embodiment of the flat plate 2, the flat plate 2 further has a sliding channel 23. The sliding channel 23 communicates with the plug-in slot 22. The sliding channel 23 is used for the push block 32 to be inserted and is in sliding fit with the push block 32. In this way, when the flat plate 2 is arranged on the base 1, the push block 32 is synchronously inserted into the sliding channel 23 and can slide along the sliding channel 23, so as to contact the electronic component 6 in the plug-in slot 22 and push the electronic component 6 in the plug-in slot 22. Among them, the sliding channel 23 can limit the direction of the push block 32 to push the electronic component 6.

[0045] Refer to Figure 1 and Figure 4 As shown, in one embodiment of the flat plate 2, the flat plate 2 has a relief opening 25. The relief opening 25 corresponds to and is adapted to the positions such as the protrusions or welding points on the surface of the circuit board 5, which can effectively prevent the flat plate 2 from damaging the important positions such as the protrusions or welding points on the surface of the circuit board 5 and ensure the quality of the circuit board 5.

[0046] Refer to Figure 1 , Figure 2 and Figure 4 As shown, in one embodiment of the flat plate 2, the notch of the circuit board slot 21 has an opening 26, which is convenient for taking out the circuit board 5 in the circuit board slot 21.

[0047] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in one embodiment of the base 1, the side surface of the base 1 has a recess 12 communicating with the limiting space 13, which is convenient for taking out the flat plate 2 placed in the limiting space 13 to replace the flat plate 2 adapted to other circuit boards 5.

[0048] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
