[0002] PCBA board (Printed Circuit Board Assembly board) is a brushed circuit board. During the production process, an automatic screw tightening machine is needed to install the PCBA circuit board body on the base.

[0003] In the related art, the same conveyor production line needs to continuously convey multiple bases of different specifications, and their heights are inconsistent.

[0032] When the workpiece moves along the conveyor line to one side of the positioning mechanism, the driving assembly drives the adjusting block to approach the base so that the adjusting station contacts the workpiece, and then the adjusting block drives the driving assembly to rise along the adjusting station so that the pressing station rises to contact the upper surface of the workpiece, and then the linkage block contacts the base, and the base pushes the linkage block to drive the adjusting block to rotate downward around the hinge, so that the adjusting block presses the workpiece through the pressing station;

[0058] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0059] After research, it is found that in the related technology, the same conveyor production line needs to continuously convey multiple bases 10 of different specifications, and their heights are inconsistent. Therefore, when screwing, the above-mentioned bases 10 of different specifications need to be positioned at the same time, so it is necessary to design multiple positioning mechanisms 3 in different positions to correspond to bases 10 of various sizes. However, the control and adjustment of multiple positioning mechanisms 3 are extremely inconvenient, and if one fails, the entire positioning mechanism 3 may need to be completely disassembled for maintenance, affecting production efficiency.

[0060] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0061] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings. In addition, in the drawings, the thickness of the components may be exaggerated or reduced in order to effectively describe the technical content.

[0062] Based on the above research, the present disclosure provides a PCBA production feeder, referring to Figure 1, including: a conveyor line 1, a screw assembly mechanism 2, and a positioning mechanism 3. The conveyor line 1 is suitable for conveying a base 10, and the base 10 is suitable for placing workpieces. The screw assembly mechanism 2 is located above the conveyor line 1, and the positioning mechanism 3 is located on one side of the conveyor line 1. The movable end of the screw assembly mechanism 2 has a screw locking member 21, and the screw locking member 21 faces the conveyor line 1. The positioning mechanism 3 corresponds to the screw locking member 21. Specifically, when the base 10 carries the workpiece and moves to one side of the positioning mechanism 3, the positioning mechanism 3 presses the workpiece and the base 10 to position them, and then the screw locking member 21 can descend and align the workpiece with the corresponding hole on the base 10 through the screw to achieve assembly.

[0063] On the other hand, in order to adapt to the bases 10 of various specifications during transportation, the positioning mechanism 3 can adaptively adjust the clamping position to ensure that the workpiece is positioned with the base 10. The positioning mechanism 3 includes a driving assembly 31 and an adjusting block 32, and the adjusting block 32 is hinged to the movable end of the driving assembly 31. The adjusting block 32 has an adjusting station 321 and a clamping station 322, and the bottom of the adjusting block 32 has a linkage block 33. The driving assembly 31 drives the adjusting block 32 to approach the base 10 so that the adjusting station 321 abuts against the workpiece. As the driving assembly 31 continues to push, the adjusting block 32 is lifted along the side wall of the workpiece through the adjusting station 321, and the adjusting block 32 drives the driving assembly 31 to be lifted synchronously until the adjusting station 321 is separated from the side wall of the workpiece, and the clamping station 322 is in contact with the upper surface of the workpiece. Then the driving assembly 31 continues to push until the linkage block 33 abuts against the base 10, and the base 10 pushes the linkage block 33, so that the linkage block 33 drives the adjustment block 32 to rotate downward around the hinge, so that the clamping station 322 synchronously presses the workpiece and the base 10 from top to bottom, thereby achieving the effect of positioning the relative position of the workpiece and the base 10.

[0064] In some embodiments, reference Figure 3 The PCBA production feeder also includes a matching component 4 and a positioning mechanism 3, which are respectively located on both sides of the conveyor line 1 and are arranged oppositely. The blocking component 5 is located in the middle of the conveyor line 1, and the blocking component 5 is suitable for lifting and lowering in the vertical direction. When the workpiece moves between the matching component 4 and the positioning mechanism 3, the blocking component 5 rises to block in front of the base 10, blocking the base 10 from continuing to be conveyed forward with the conveyor line 1, and then the positioning mechanism 3 and the matching component 4 clamp the two sides of the base 10 from both sides to position the base 10. Then, the workpiece and the base 10 can be positioned by the driving component 31 and the adjusting block 32, and finally the screw is locked by the screw locking member 21. In the above process, the workpiece and the base 10 are pressed from top to bottom by the pressing station 322, which can also avoid the problem of over-travel extrusion of the workpiece to ensure the pressing effect in the conventional design when the workpiece is pressed by the left and right sides, resulting in damage to the workpiece.

[0065] In at least one embodiment, reference Figure 1 Optionally, the adjusting block 32 has an inclined surface on one side facing the workpiece to form an adjusting station 321. The adjusting station 321 is inclined toward one side of the workpiece in the height direction. Through the above arrangement, when the driving component 31 drives the adjusting block 32 to approach the workpiece in the horizontal direction, the adjusting station 321 abuts against the side wall of the workpiece. As the driving component 31 continues to transport, the workpiece can apply a reaction force to the adjusting block 32 through the inclined surface where the adjusting station 321 is located, so that the adjusting block 32 is lifted along the adjusting station 321 until the pressing station 322 fits against the upper surface of the workpiece.

[0066] In some embodiments, reference Figure 1 For the size of the base 10 within the optional range, it is only necessary to keep the highest height of the adjustment station 321 higher than the upper surface of the workpiece, and the lowest height of the adjustment station 321 lower than the upper surface of the workpiece, so as to achieve the effect that when the drive assembly 31 drives the adjustment block 32 to approach the workpiece in the horizontal direction, the adjustment block 32 is lifted along the adjustment station 321. This avoids the problem of installing multiple sets of mechanisms to achieve positioning of bases 10 of different sizes.

[0067] In at least one embodiment, reference Figure 6 , a number of vents 323 are provided on the clamping station 322 and the adjusting station 321. The adjusting block 32 is hollow inside and can be connected to an external power device through an air pipe to achieve the effect of suction or blowing. The clamping station 322 is also provided with a proximity switch. It should be noted that in order to enhance the performance of the screw, a loose coating will be applied on the outer wall of the screw thread. After the screw locking member 21 tightens the screw, part of the coating will fall off and remain on the upper surface of the workpiece, affecting the appearance. Therefore, after the screw locking member 21 tightens the screw, the vents 323 on the adjusting station 321 blow air outward to remove debris on the upper surface of the workpiece. On the other hand, after the blowing is completed, the vent hole 323 on the pressing station 322 inhales air, and when the driving assembly 31 retreats, the adjusting block 32 is lifted. At this time, if the screw locking member 21 correctly drives the screw into the workpiece and the base 10, the workpiece connection is firm, and the vent hole 323 of the pressing station 322 cannot suck up the workpiece. If the screw locking member 21 does not correctly drive the screw into the workpiece and the base 10, the workpiece connection is loose and has a certain amount of room for movement. At this time, the pressing station 322 can suck up the workpiece through the vent hole 323. At this time, the proximity switch can be used to determine whether the workpiece is sucked up and whether the screw is firmly locked.

[0068] In order to achieve the effect of driving the adjusting block 32 to move horizontally by the driving component 31, refer to Figure 5The driving assembly 31 includes a driving cylinder 311 and a movable seat 312 installed at the movable end of the driving cylinder 311, and the adjusting block 32 is hinged to the movable seat 312. At the same time, a torsion spring is provided at the hinge between the adjusting block 32 and the movable seat 312, so that the adjusting block 32 can maintain a relatively fixed position with the movable seat 312 when no external force is applied.

[0069] In order to guide the effect of the driving assembly 31 rising and falling with the adjusting block 32, refer to Figure 5 The positioning mechanism 3 further includes a U-shaped cover 34, and the driving assembly 31 is slidably disposed in the U-shaped cover 34. When the adjustment block 32 is lifted, the driving assembly 31 can be lifted and lowered along the inner wall of the U-shaped cover 34.

[0070] In order to achieve the effect of positioning the base 10, refer to Figure 4 and Figure 5 The positioning mechanism 3 further includes a bracket 35 and a positioning assembly 36 mounted on the bracket 35, and the positioning assembly 36 includes a positioning cylinder 361 and a positioning block 362 mounted on the movable end of the positioning cylinder 361. The positioning block 362 corresponds to the base 10. At the same time, the matching assembly 4 includes a matching cylinder 41 and a clamping block 42 mounted on the movable end of the matching cylinder 41. When the base 10 moves between the positioning assembly 36 and the matching assembly 4, the positioning cylinder 361 and the matching cylinder 41 respectively drive the positioning block 362 and the clamping block 42 to move toward each other, so as to clamp the base 10 from both sides.

[0071] In order to achieve the effect of blocking the base 10 from moving forward, refer to Figure 4 The blocking assembly 5 comprises a blocking cylinder 51 and a lifting block 52 installed at the movable end of the blocking cylinder 51. The blocking cylinder 51 is installed at the bottom of the conveying line 1, and the movable end of the blocking cylinder 51 is vertically arranged upward.

[0072] Reference Figure 2The screw assembly mechanism 2 includes an assembly frame 22, which has a horizontal slide rail 221, on which a translation seat 222 is slidably arranged, and a translation motor 223 is installed on one side of the assembly frame 22, and a screw rod is installed on the movable end of the translation motor 223, and the screw rod is threadedly connected with the translation seat 222. When the translation motor 223 is started, the translation seat 222 can be driven to slide along the horizontal slide rail 221 through the screw rod. The translation seat 222 has a vertical slide rail 224, on which a lifting seat 225 is slidably arranged, and a vertical cylinder 226 is installed on the translation seat 222, and the movable end of the vertical cylinder 226 is connected to the lifting seat 225. The lifting seat 225 is installed with an assembly motor 227, and the screw locking member 21 is installed on the movable end of the assembly motor 227. When the vertical cylinder 226 is started, the lifting seat 225 can be driven to rise and fall along the vertical slide rail 224. When the assembly motor 227 is started, the screw locking member 21 can be driven to rotate so that the screw locking member 21 can lock the screw.

[0073] At least one embodiment provides a PCBA production feeder, referring to Figure 1 , including: a conveyor line 1, a screw assembly mechanism 2, and a positioning mechanism 3. The conveyor line 1 is suitable for conveying a base 10, and the base 10 is suitable for placing workpieces. The screw assembly mechanism 2 is located above the conveyor line 1, and the positioning mechanism 3 is located on one side of the conveyor line 1. The movable end of the screw assembly mechanism 2 has a screw locking member 21, and the screw locking member 21 faces the conveyor line 1. The positioning mechanism 3 corresponds to the screw locking member 21. Specifically, when the base 10 carries the workpiece and moves to one side of the positioning mechanism 3, the positioning mechanism 3 presses the workpiece and the base 10 to position them, and then the screw locking member 21 can descend and align the workpiece with the corresponding hole on the base 10 through the screw to achieve assembly.

[0074] On the other hand, in order to adapt to the bases 10 of various specifications during transportation, the positioning mechanism 3 can adaptively adjust the clamping position to ensure that the workpiece is positioned with the base 10. The positioning mechanism 3 includes a driving assembly 31 and an adjusting block 32, and the adjusting block 32 is hinged to the movable end of the driving assembly 31. The adjusting block 32 has an adjusting station 321 and a clamping station 322, and the bottom of the adjusting block 32 has a linkage block 33. The driving assembly 31 drives the adjusting block 32 to approach the base 10 so that the adjusting station 321 abuts against the workpiece. As the driving assembly 31 continues to push, the adjusting block 32 is lifted along the side wall of the workpiece through the adjusting station 321, and the adjusting block 32 drives the driving assembly 31 to be lifted synchronously until the adjusting station 321 is separated from the side wall of the workpiece, and the clamping station 322 is in contact with the upper surface of the workpiece. Then the driving assembly 31 continues to push until the linkage block 33 abuts against the base 10, and the base 10 pushes the linkage block 33, so that the linkage block 33 drives the adjustment block 32 to rotate downward around the hinge, so that the clamping station 322 synchronously presses the workpiece and the base 10 from top to bottom, thereby achieving the effect of positioning the relative position of the workpiece and the base 10.

[0075] Reference Figure 1 Optionally, the adjustment block 32 has an inclined surface on one side facing the workpiece to form an adjustment station 321. The adjustment station 321 is inclined toward one side of the workpiece in the height direction. The inclination angle is 40°-55°, wherein when the inclination angle is 40°, it is suitable for a drive assembly 31 with a larger torque and a shorter stroke, and when the inclination angle is 55°, it is suitable for a drive assembly 31 with a smaller torque and a longer stroke. Through the above arrangement, when the drive assembly 31 drives the adjustment block 32 to approach the workpiece in the horizontal direction, the adjustment station 321 abuts against the side wall of the workpiece, and as the drive assembly 31 continues to be transported, the workpiece can apply a reaction force to the adjustment block 32 through the inclined surface where the adjustment station 321 is located, so that the adjustment block 32 is lifted along the adjustment station 321 until the pressing station 322 fits against the upper surface of the workpiece.

[0076] Reference Figure 1 For the size of the base 10 within the optional range, the two ends of the adjustment station 321 are respectively located at the upper and lower sides of the workpiece, so that the effect of the adjustment block 32 being lifted along the adjustment station 321 when the driving assembly 31 drives the adjustment block 32 to approach the workpiece in the horizontal direction can be achieved. This avoids the problem of installing multiple sets of mechanisms to achieve positioning of bases 10 of different sizes.

[0077] Reference Figure 6, a number of vents 323 are provided on the clamping station 322 and the adjusting station 321. The adjusting block 32 is hollow inside and can be connected to an external power device through an air pipe to achieve the effect of suction or blowing. The clamping station 322 is also provided with a proximity switch. It should be noted that in order to enhance the performance of the screw, a loose coating will be applied on the outer wall of the screw thread. After the screw locking member 21 tightens the screw, part of the coating will fall off and remain on the upper surface of the workpiece, affecting the appearance. Therefore, after the screw locking member 21 tightens the screw, the vents 323 on the adjusting station 321 blow air outward to remove debris on the upper surface of the workpiece. On the other hand, after the blowing is completed, the vent hole 323 on the pressing station 322 inhales air, and when the driving assembly 31 retreats, the adjusting block 32 is lifted. At this time, if the screw locking member 21 correctly drives the screw into the workpiece and the base 10, the workpiece connection is firm, and the vent hole 323 of the pressing station 322 cannot suck up the workpiece. If the screw locking member 21 does not correctly drive the screw into the workpiece and the base 10, the workpiece connection is loose and has a certain amount of room for movement. At this time, the pressing station 322 can suck up the workpiece through the vent hole 323. At this time, the proximity switch can be used to determine whether the workpiece is sucked up and whether the screw is firmly locked.

[0078] In addition, at least one embodiment further provides a PCBA production process, which uses the PCBA production feeder as described above for production, including the following steps:

[0079] Step S1, the workpiece moves along the conveyor line 1 to one side of the positioning mechanism 3;

[0080] Step S2, the driving assembly 31 drives the adjusting block 32 to approach the base 10, so that the adjusting station 321 abuts against the workpiece;

[0081] Step S3, the adjusting block 32 drives the driving assembly 31 to rise along the adjusting station 321, so that the pressing station 322 rises to fit the upper surface of the workpiece;

[0082] In step S4 , the linkage block 33 abuts against the base 10 , and the base 10 pushes the linkage block 33 to drive the adjustment block 32 to rotate downward around the hinge, so that the adjustment block 32 passes through the pressing station 322 to press the workpiece.
